Description

Interior door lock function verification device

Technical Field

The invention belongs to the technical field of automobile detection, and in particular relates to a device for verifying the function of an interior door lock of a vehicle.

Background technique

New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, etc.

In recent years, electric vehicles have developed rapidly and have been widely promoted and applied. With this, there have been frequent safety accidents, especially electric vehicle fire accidents, and most of them are related to the power batteries carried. Therefore, the fire resistance of electric vehicles is directly related to the personal and property safety of drivers and passengers. At present, the detection of new energy vehicles is not perfect enough, and there is a lack of detection equipment for whether the vehicle doors can be opened from the inside. Therefore, in the whole vehicle fire test of new energy vehicles, it is impossible to simulate the driver and passengers manually opening the door from the inside of the vehicle, and it is impossible to verify the functionality of the door lock inside the vehicle.

Summary of the invention

The present invention aims to solve the technical problems existing in the prior art, and the purpose of the present invention is to provide a device for verifying the function of an interior door lock.

To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a vehicle interior door lock function verification device, comprising a pushing mechanism and an unlocking mechanism; the pushing mechanism comprises a front housing that can be fixedly installed on the inner side of the vehicle door, a push plate that can abut against the vehicle operation panel, a connecting rod, and a thrust device and a slider installed in the front housing, the slider is slidably installed in the front housing along the front and rear directions of the vehicle door and is connected to the front end of the thrust device, the push plate is hinged at the front end of the front housing, and the two ends of the connecting rod are respectively rotatably connected with the push plate and the slider to form a planar rocker slider mechanism; the unlocking mechanism comprises a rear end fixedly connected to the front housing The invention also comprises a rear housing fixedly installed on the inner side of the vehicle door, a push rod installed in the rear housing, and a swing arm rotatably installed on the outside of the rear housing through a first vertical rotating shaft fixed thereto; the push rod is slidably installed in the rear housing along the front-rear direction of the vehicle door and extends into the front housing to be fixedly connected to the rear end of the thrust device; the thrust device can generate a thrust to make the slider slide forward and the push rod slide forward or backward; a clamping block capable of being clamped with the handle inside the vehicle door is connected to one end of the swing arm away from the first vertical rotating shaft; the push rod and the first vertical rotating shaft are connected through a transmission assembly so that the swing arm is driven by the push rod to swing.

In the above technical scheme, before the whole vehicle fire test, the verification device is installed on the inner side of the vehicle door. During the whole vehicle fire test, the thrust device is started, and the thrust generated by it acts on the slider and the push rod, and then the push rod drives the swing arm to swing, so that the card block drives the handle inside the door to move and open, thereby unlocking the door lock; at the same time, the slider tends to slide forward due to the thrust of the thrust device. If the door can be opened, the slider slides forward, and the angle between the push plate and the front shell body is opened through the force of the connecting rod to open the door; if the door cannot be opened, the slider is stuck and cannot slide, and the door cannot be opened.

The verification device of the present invention can simulate the action of a driver or passenger manually opening a door in a vehicle to meet the need of detecting whether the door of the vehicle can be opened from the inside, so as to verify whether the function of the door lock in the vehicle is normal.

In a preferred embodiment of the present invention, the thrust device includes an outer sleeve, an inner sleeve, a first spring, a bayonet and a push-pull electromagnet. The outer sleeve and the inner sleeve are buckled together and slidably cooperate with each other to form a thrust frame. The slider and the push rod are respectively connected to the front end and the rear end of the thrust frame. The first spring is pressed into the thrust frame formed by the outer sleeve and the inner sleeve. The side walls of the outer sleeve and the inner sleeve are each provided with a pin hole. The two pin holes can be aligned and inserted into the bayonet to lock after the first spring is compressed. The push-pull electromagnet is fixedly installed on the front shell body and connected to the bayonet pin, which is used to control the bayonet pin to enter or exit the pin hole of the inner sleeve.

In the above technical solution, during the detection process, the push-pull electromagnet is controlled outside the vehicle to operate, so that it drives the bayonet pin to withdraw from the pin hole of the inner sleeve, thereby releasing the elastic force of the first spring, thereby generating a forward thrust on the slider and a backward thrust on the push rod; after the test, the push plate and the push rod can be pressed back to the initial position (reset) and the pin holes of the outer sleeve and the inner sleeve can be clamped again with the bayonet pin, so that the verification device can be reused.

In a preferred embodiment of the present invention, the outer sleeve is located at the rear side of the inner sleeve, the outer sleeve is a cylindrical structure with an opening at the front end, and the inner sleeve is a cylindrical structure with an opening at the rear end, and slideways are respectively provided in the front shell body corresponding to the outer sleeve and the inner sleeve.

In the above technical solution, the slideway has a limiting and guiding effect on the sliding of the outer sleeve and the inner sleeve, which facilitates the movement and resetting of the slider and the push rod.

In a preferred embodiment of the present invention, a second spring sleeved outside the push rod is also installed in the slideway of the outer sleeve, and the thrust frame is elastically connected to the outer shell through the second spring, and the elastic coefficient of the second spring is smaller than the elastic coefficient of the first spring.

In the above technical solution, by providing a second spring, the entire thrust device can be pushed to the front side by the elastic force of the second spring before the elastic force of the first spring is released, so as to keep the push rod in the initial position, and drive the swing arm to have a sufficient swing amplitude during subsequent tests, so as to ensure that the door is effectively unlocked; and the elastic coefficient of the second spring is smaller than the elastic coefficient of the first spring, so as to ensure that the second spring can be compressed and drive the push rod to move backward after the elastic force of the first spring is released.

In a preferred embodiment of the present invention, the transmission assembly includes a first gear set, a first rack extending along the length direction of the push rod is fixedly connected to one side of the push rod, the first gear set includes a driven gear meshing with the first rack, and a linkage gear coaxially arranged with the driven gear and capable of rotating therewith, the first vertical rotating shaft is fixedly connected to an output gear capable of meshing with the outside of the linkage gear, and the driven gear, the linkage gear and the output gear can all be rotatably installed in the rear housing.

In the above technical solution, the linear motion of the push rod in the front-to-rear direction is converted into the horizontal rotational motion of the driven gear through the gear rack pair of the first rack and the driven gear, the height position is changed by the coaxially arranged driven gear and the linkage gear, and the horizontal position is changed by the linkage gear and the output gear, so that the rocker arm finally has a sufficient swing amplitude to ensure the effective unlocking of the door.

In another preferred embodiment of the present invention, the transmission assembly also includes a non-circular connecting shaft and a second gear set with the same structure as the first gear set. The push rod is located on the opposite side of the first rack and is fixedly connected to the second rack. The driven gear of the second gear set is meshed with the second rack, and the linkage gear of the second gear set is also meshed with the output gear. The centers of the driven gears and linkage gears of the two gear sets are provided with non-circular holes that can be plugged and matched with the non-circular connecting shaft. The driven gears and linkage gears are respectively installed in the rear housing with a single degree of freedom for rotation. The non-circular connecting shaft can be selectively inserted into the non-circular holes of the driven gear and the linkage gear of one of the gear sets through the through hole on the top of the rear housing.

In the above technical solution, two gear sets are provided, and the two gears of each gear set can rotate with a single degree of freedom respectively. The non-circular connecting shaft is inserted into different gear sets. Under the action of the thrust device, the push rod drives the swing arm to swing in different directions (forward or backward). Since the orientation of the inner door handles of different models is not completely consistent, some are forward and some are backward, the structural design of the above transmission assembly can select the non-circular connecting shaft to be inserted into the corresponding gear set according to the orientation of the inner door handle, thereby improving the versatility of the verification device.

In another preferred embodiment of the present invention, the connecting rod comprises a front rod and a rear rod, and the front rod and the rear rod are coaxially slidably matched and fastened by a locking screw.

In the above technical solution, the length of the connecting rod is adjustable. Therefore, for different vehicle models, after the front shell and the rear shell are fixed on the inside of the door, the push plate can be close to the car operation panel by adjusting the length of the connecting rod, thereby further improving the versatility of the verification device.

In another preferred embodiment of the present invention, the clamping block is a U-shaped block with an open lower end that can be clamped on the inner door handle, or the clamping block is an annular block that can be sleeved on the inner door handle.

In the above technical solution, both the U-shaped block and the annular block can be quickly connected to the inner door handle of the vehicle, and the swing of the swing arm drives the inner door handle to move and unlock the door lock.

In another preferred embodiment of the present invention, the clamping block is rotationally connected to the swing arm via a second vertical rotating shaft.

In the above technical scheme, since there is a certain horizontal distance between the first vertical rotation axis of the swing arm and the rotation axis of the inner door handle, a certain degree of relative position change occurs between the swing arm and the inner door handle during the swinging process. If the clamping block is fixedly connected to the swing arm, it is necessary to increase the inner space width of the clamping block, so that the matching accuracy between the clamping block and the inner door handle decreases and the stability becomes worse. The clamping block of this scheme is installed on the swing arm through the second vertical rotation axis, which can make the clamping block freely rotate around the second vertical rotation axis, thereby adapting to the above-mentioned relative position change, and can relatively reduce the inner space width of the clamping block and maintain effective engagement with the inner door handle.

In another preferred embodiment of the present invention, both the front shell and the rear shell are provided with connecting ears for fixed connection with the inner side of the vehicle door.

In the above technical solution, by providing the connecting ears, people can use screws to pass through the connecting ears to fix the front shell and the rear shell on the inner side of the door, which is convenient for installation.

Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

The present invention provides a vehicle interior door lock function verification device (referred to as verification device). In a preferred embodiment of the present invention, the verification device includes a pushing mechanism and an unlocking mechanism.

As shown in Fig. 1 and Fig. 2, the pushing mechanism includes a front housing 10 that can be fixedly installed on the inner side of the vehicle door 26, a push plate 18 that can abut against the vehicle operation panel 27, a connecting rod 29, and a thrust device 29 and a slider 8 installed in the front housing 10. The slider 8 is slidably installed in the front housing 10 along the front and rear direction of the vehicle door 26 and connected to the front end of the thrust device 29, the push plate 17 is hinged to the front end of the front housing 10 through a link, and the two ends of the connecting rod 29 are respectively connected to the push plate 18 and the slider 8 through a pin to form a plane rocker slider mechanism.

As shown in Fig. 1, Fig. 2 and Fig. 4, the unlocking mechanism includes a rear housing 3 fixedly connected to the rear end of the front housing 10 and capable of being fixedly installed on the inner side of the vehicle door 26, a push rod 2 installed in the rear housing 3, and a swing arm 22 rotatably installed outside the rear housing 3 through a first vertical rotating shaft 21 fixed thereto, for example, the swing arm 22 is installed on the bottom surface of the rear housing 3. The push rod 2 is slidably installed in the rear housing 3 along the front-rear direction of the vehicle door 26 and extends into the front housing 10 and is fixedly connected to the rear end of the thrust device 28. The thrust device 28 can generate a forward force on the slider 8 and can generate a forward or backward force on the push rod 2. The thrust device 28 refers to a device that can provide thrust along a straight line, such as a hydraulic cylinder, a pneumatic cylinder, a linear motor, etc., which can meet its functions.

One end of the swing arm 22 is rotatably mounted on the bottom surface of the rear housing 3 via the first vertical shaft 21, and the other end of the swing arm 22 is connected to a clamping block 24 that can be clamped with the inner door handle. The push rod 2 and the first vertical shaft 21 are connected by a transmission assembly 30, so that the swing arm 22 is driven by the push rod 2 to swing. In the present invention, the clamping block 24 is a U-shaped block with an opening at the lower end that can be clamped on the inner door handle, or the clamping block 24 is an annular block that can be sleeved on the inner door handle.

Before the whole vehicle fire test of the new energy vehicle, the front housing 10 and the rear housing 3 of the verification device are fixedly installed on the inner side of the door 26, the block 24 is clamped on the inner handle of the door, and the front end surface of the push plate 17 is placed against the vehicle operation panel 27. During the whole vehicle fire test, by starting the thrust device 28, the thrust generated by the thrust device 28 acts on the slider 8 and the push rod 2, and then the push rod 2 drives the swing arm 22 to swing, so that the block 24 drives the inner handle of the door to move to open and unlock the door lock. The slider 8 has a tendency to slide forward due to the thrust of the thrust device 28. If the door 26 can be opened, the slider 8 slides forward, and the angle between the push plate 17 and the front housing 10 is opened by the force of the connecting rod 29, so that the door 26 is opened; if the door 26 cannot be opened, the slider 8 is stuck and cannot slide, and the door 26 cannot be opened.

As shown in Figures 2 and 3, in another preferred embodiment, the thrust device 28 includes an outer sleeve 5, an inner sleeve 7, a first spring 6, a bayonet 12 and a push-pull electromagnet 13. The outer sleeve 5 and the inner sleeve 7 are buckled together and slidably matched with each other to form a thrust frame, and the slider 8 and the push rod 2 are respectively connected to the front and rear ends of the thrust frame. The first spring 6 is pressed into the cavity formed between the outer sleeve 5 and the inner sleeve 7 (that is, the first spring 6 is located in the thrust frame). The side walls of the outer sleeve 5 and the inner sleeve 7 are each provided with a pin hole, and the two pin holes are aligned after the first spring 6 is compressed and inserted into the bayonet 12 to lock. The push-pull electromagnet 13 is fixedly mounted on the front housing 10 and connected to the bayonet 12, and is used to control the bayonet 12 to enter or exit the pin hole of the inner sleeve 7.

As shown in FIG2 , the first spring 6 of the present embodiment is pre-compressed between the outer sleeve 5 and the inner sleeve 7, and the bayonet 12 is inserted into the pin holes of the outer sleeve 5 and the inner sleeve 7 to lock the two. As shown in FIG3 , during the detection process, by controlling the push-pull electromagnet 13 to act outside the vehicle, the push-pull electromagnet 13 drives the bayonet 12 to withdraw from the pin hole of the inner sleeve 7, and the elastic force of the first spring 6 can be released, so that the inner sleeve 7 slides forward and the outer sleeve 5 slides backward, thereby making the inner sleeve 7 push the slider 8 to slide forward, and the inner sleeve 7 pushes the push rod 2 to slide backward. By reasonably setting the length of the outer sleeve 5 and the inner sleeve 7, the two can be kept in contact without separation. After the test, the push plate 17 and the push rod 2 can be pressed back to the initial position (reset) and the bayonet 12 can be used to clamp the pin holes of the outer sleeve 5 and the inner sleeve 7 again.

As shown in Figures 2 and 3, in another preferred embodiment, the outer sleeve 5 is located on the rear side of the inner sleeve 7, the outer sleeve 5 is a cylindrical structure with an opening at the front end, and the inner sleeve 7 is a cylindrical structure with an opening at the rear end, and slideways 9 are respectively provided in the front shell body 10 corresponding to the outer sleeve 5 and the inner sleeve 7.

As shown in Fig. 2 and Fig. 3, in another preferred embodiment, a second spring 4 is installed in the slideway 9 of the outer sleeve 5 and is sleeved outside the push rod. The second spring 4 is a tower spring. The outer sleeve 5 of the thrust frame is elastically connected to the outer shell 10 through the second spring. The second spring 4 is used to provide a forward thrust for the outer sleeve 5. The elastic coefficient of the second spring 4 is smaller than the elastic coefficient of the first spring 6, ensuring that the second spring 4 can be compressed and drive the push rod 2 to move after the elastic force of the first spring 6 is released; at the same time, the second spring 4 is set, and before the elastic force of the first spring 6 is released, the elastic force of the second spring 4 can push the entire thrust device 29 to the front side, thereby keeping the push rod 2 in the initial position, and driving the swing arm 22 to have a sufficient swing amplitude in the subsequent test process, ensuring that the door 26 is effectively unlocked.

As shown in FIG. 2 , in another preferred embodiment, the connecting rod 29 includes a front rod 16 and a rear rod 15, which are coaxially slidably matched and fastened by a locking screw 14. Thus, the length of the connecting rod 29 can be changed by adjusting the locking screw 14. For different vehicle models, after the front housing 10 and the rear housing 3 are fixed to the inner side of the vehicle door 26, the push plate 17 can be closely abutted against the vehicle operation panel 27 by adjusting the length of the connecting rod 29.

As shown in FIG4 , in another preferred embodiment, the block 24 is rotatably connected to the swing arm 22 via the second vertical rotating shaft 23. Since there is a certain distance between the first vertical rotating shaft 21 of the swing arm 22 and the rotating shaft of the inner door handle, a certain degree of relative position change occurs between the swing arm 22 and the inner door handle during the swinging process. If the block 24 is fixed to the swing arm 22, it is necessary to increase the inner space width of the block 24 (referring to the U-shaped opening width of the U-shaped block or the inner space width of the annular block), thereby reducing the matching accuracy between the block 24 and the inner door handle and deteriorating the stability; installing the block 24 on the swing arm 22 via the second vertical rotating shaft 23 can make the block 24 rotate freely around the second vertical rotating shaft 23, thereby adapting to the above-mentioned relative position change, and relatively reducing the inner space width of the block 24, and maintaining effective engagement with the inner door handle.

As shown in FIG. 2 and FIG. 4 , in one embodiment of the present invention, the transmission assembly 30 includes a first gear set, for example, the first gear set is arranged on the right side of the push rod 2 shown in FIG. 4 . A first rack extending along the length direction of the push rod 2 is fixedly connected to the right side of the push rod 2, and the first gear set includes a driven gear 11 meshing with the first rack, and a linkage gear 19 coaxially arranged with the driven gear 11 and capable of rotating therewith, for example, the driven gear 11 and the linkage gear 19 are connected by a transmission shaft or the two are fixedly connected. An output gear 20 capable of externally meshing with the linkage gear 19 is fixedly connected to the upper end of the first vertical shaft 21, and the output gear 20 is located directly below the push rod 2, and the driven gear 11, the linkage gear 19 and the output gear 20 can all be rotatably mounted in the rear housing 3.

As shown in Figure 1, for the purpose of explanation, with the direction of the inner door handle facing backward, it can be seen from Figures 2 to 4 that the elastic force released by the first spring 6 causes the outer sleeve 5 to slide backward, the outer sleeve 5 causes the push rod 2 to slide backward, the first rack on the push rod 2 causes the driven gear 11 on the right to rotate counterclockwise (looking down at the driven gear), the linkage gear 19 rotates counterclockwise with the driven gear 11, the linkage gear 19 causes the output gear 20 to rotate clockwise, and the output gear 20 causes the swing arm 22 to swing backward through the first vertical shaft 21 to pull open the inner door handle.

As shown in Figures 2 and 5, it is further preferred that the transmission assembly 30 also includes a non-circular connecting shaft 1 and a second gear set with the same structure as the first gear set. The second gear set is arranged on the left side of the push rod 2, and the two gear sets are symmetrically arranged. The non-circular connecting shaft 1 can be an elliptical shaft, a square shaft, a trapezoidal shaft, a triangular shaft, etc., as long as it is not a circular shaft and can transmit torque. A second rack is fixedly connected to the left side of the push rod 2, and the driven gear 11 of the second gear set is meshed with the second rack, and the linkage gear 19 of the second gear set is also meshed with the output gear 20.

The centers of the driven gears 11 and the linkage gears 19 of the two gear sets are both provided with non-circular holes 18 that can be plugged and matched with the non-circular connecting shaft 1. For example, if the non-circular connecting shaft 1 is a square shaft, the non-circular hole 18 is a square hole. The driven gears 11 and the linkage gears 19 of each gear set are respectively installed in the rear housing 3 with a single degree of freedom for rotation. The non-circular connecting shaft 1 can be selectively inserted into the non-circular hole 18 of the driven gear 11 and the linkage gear 19 of one of the gear sets through the through hole at the top of the rear housing 3.

By adopting the above technical solution, if the non-circular connecting shaft 1 is inserted into the non-circular hole 19 of the right driven gear 11 and the linkage gear 19, when the push rod 2 slides backward, only the linkage gear 19 on the right side rotates counterclockwise with the right driven gear 11, so that the swing arm 22 swings backward to pull the door handle facing backward, the left driven gear 11 and the linkage gear 19 on the left side slip, and the linkage gear 19 on the left side does not rotate with the left driven gear 11. On the contrary, if the non-circular connecting shaft 1 is inserted into the non-circular hole 19 of the left driven gear 11 and the linkage gear 19, when the push rod 2 slides backward, only the linkage gear 19 on the left side rotates clockwise and counterclockwise with the left driven gear 11, so that the swing arm 22 swings forward to pull the door handle facing forward, the right driven gear 11 and the linkage gear 19 on the right side slip, and the linkage gear 19 on the right side does not rotate with the right driven gear 11.

As shown in FIG1 , in another preferred embodiment, the front housing 10 and the rear housing 3 are respectively provided with connecting ears 25 for fixing with the vehicle door 26. During installation, holes can be drilled in advance on the vehicle door interior panel, and then screws are passed through the connecting ears 25 to fix the front housing 10 and the rear housing 3 to the inner side of the vehicle door 26, which is convenient for installation; and in order to adapt to the curved surface structure of the vehicle door interior panel, a support sleeve of a suitable length can be put on the part where the screw passes through the connecting ears 25 to ensure the stability of the fixed installation of the front housing 10 and the rear housing 3.
