Description

Wire connection mechanism and wiring structure for two-wheeled electric vehicle

technical field

The invention relates to an electric vehicle, in particular to a foldable two-wheel electric vehicle.

Background technique

With the increasingly severe traffic conditions in modern cities, electric vehicles are more and more accepted by the public due to their convenience, environmental protection and other advantages. Traditional electric vehicles are usually bulky, heavy, and inconvenient to carry, which is not conducive to the conversion between public transportation and road driving. At this time, portable folding electric vehicles appear as alternatives that can be carried on public transportation such as subways.

Most of the existing folding electric vehicles directly fold the handlebar and the vehicle body together, but there are some defects in the traditional folding method. For example, the folded vehicle body needs to be carried by one end of the wheel to move the electric vehicle. However, because the electric vehicle is equipped with battery packs and other equipment, it is too heavy and inconvenient to carry. Furthermore, in the traditional folding method, the length of the folded body remains unchanged, and it needs to occupy a lot of space in transportation means such as subways. Therefore, if there is dirt on the wheels, it is easy to stain other people's clothes. In addition, the layout of the transmission lines used to transmit signals/power on the folded body of a traditional electric vehicle is unreasonable, so that the folded body occupies a large space, and the transmission line is easily damaged when it is carried.

Therefore, there is a need for a folding electric vehicle with an improved folding mechanism to overcome the defects of traditional folding electric vehicles.

For the charging and discharging signal of the power supply 223, the cruising mode control signal of the motor 224, the deceleration signal of the braking device 225, etc., the second control circuit 222 arranged inside the platform type rear frame 115 of the rear vehicle body 102 carries out these signals. processing and sending. The first control circuit 203 and the second control circuit 222 are integrated circuit boards with functions of digital-to-analog conversion, data calculation, and data sending and receiving. The second control circuit 222 processes and sends the charging and discharging signals, cruise mode control signals, deceleration signals, etc. to the first control circuit 203, so that the first control circuit 203 processes the above signals and sends them to the display device 204, so that the display device 204 displays Battery information, cruise mode information, speed information, etc. The first control circuit 203 processes the control signal sent by the control mechanism 205 and sends it to the second control circuit 222, so that the second control circuit 222 processes and controls the action of corresponding components (such as the motor 224 and the braking device 225).

As an example, there are four front wires 211 inside the front body 101, which are positive power wires 211.1, negative power wires 211.2, and two signal wires 211.3 and 211.4. The positive and negative power wires 211.1 and 211.2 are used for operating voltage For transmission, the signal lines 211.3 and 211.4 are used for signal transmission. One end of the four front wires 211 is connected to the first control circuit 203 , and the other end is connected to the front body wire connecting device 201 arranged in the front body cover 107 .

In this embodiment, four rear wires 231 are arranged in the rear body 102 in cooperation with the front wires 211, which are respectively positive power wires 231.1, negative power wires 231.2 and two signal wires 231.3, 231.4. The rear wires 231 The function is exactly the same as the front wire 211. One end of the signal lines 231.3, 231.4 of the two rear conductors 231 is connected to the second control circuit 222, and the other end is connected to the rear vehicle body conductor connection device 221 arranged in the rear vehicle body cover 108; the signal lines of the two rear conductors 231 are positive power supplies One end of the line 231.1 and the negative power line 231.2 are connected to the power supply 223, and the other end is connected to the rear vehicle body wire connection device 221.

In fact, if the battery 227 for independent power supply is provided in the front body 101, the working voltage of the components and circuits in the front body 101 can be independently supplied by the battery 227 instead of the power supply 223 in the rear body 102. Therefore, the positive power line and the negative power line used to transmit power in the front wire 211 and the rear wire 231 are no longer needed.

In addition, in the wiring structure according to the first embodiment of the present invention as shown in FIG. 2A, the front wire 211 and the rear wire 231 use two signal wires 211.3, 211.4, 231.3 and 231.4 as connecting wires for signal transmission, but In fact, the transmission of signals can also be realized by using a wire.

Therefore, in the wiring structure according to the second embodiment of the present invention as shown in FIG. 2D, an independent battery 227 is provided in the front body 101, and the battery 227 is connected to the first control circuit 203, and the first control circuit 203 is connected to the control circuit.

The first control circuit 203 is connected to the front vehicle body wire connection device 201 through a front wire 211 . In the rear vehicle body 102, the second control circuit 222 is connected to the rear vehicle body wire connection device 221 through a rear wire 231.1. Other wiring structures in the rear vehicle body 102 are the same as those in FIG. 2A , and will not be repeated here.

At this time, at least one contact point needs to be set on the front vehicle body wire connecting device 201, and at least one contact pin only needs to be set on the rear vehicle body wire connecting device 221, and the front vehicle body wire connecting device 201 and the rear vehicle body wire are connected. When the devices 221 are in close contact with each other, one contact pin and one contact point contact each other, so that one front wire 211 communicates with one rear wire 231, thereby realizing signal communication between the front body 101 and the rear body 102 .

In fact, a plurality of redundant contacts and contact pins are provided on the front vehicle body wire connection device 201 and the rear vehicle body wire connection device 221 to ensure the reliability of the contact connection.

Furthermore, Figures 2A and 2D merely show two embodiments of the present invention, as illustrative examples. No matter how many signal lines are used, no matter whether the front body is provided with a power line, or any combination thereof, these are all within the protection scope of the present invention.

Moreover, the locking mechanism 320 can also realize the connection and separation of the front vehicle body wire connection device 201 and the rear vehicle body wire connection device 221 . As can be seen from FIG. 3A-1, the triggering mechanism 130 for controlling the locking and releasing of the locking mechanism 320 faces the horizontal direction (same as FIG. 1E ) at this time to release the locking mechanism 320, while the triggering mechanism 130 is shown in FIG. 3A- 2, it faces the vertical direction (same as FIG. 1D ), so as to realize the locking of the locking mechanism 320 .

3B-1 is a sectional view of FIG. 3A-1 along line A-A, and FIG. 3B-2 is a sectional view of FIG. 3A-2 along line B-B. FIGS. 3B-1 and 3B-2 are mainly used to show the locking mechanism 320 The difference between the locked position and the released position. As shown in Figures 3B-1 and 3B-2, the locking mechanism 320 mainly includes a locking pressure block 314, a locking slider 324 (see Figures 3D-1 to 3D-3 for details) and a drive shaft 330 (see Figure 3E-1 for details). ~ Figure 3E-3). The locking pressure piece 314 can be pushed through the first engaging window 318 on the front engaging plane 308, thereby pressing against the rear engaging plane 311 of the front body cover 107 located in the rear body cover 108 (hereinafter 3I-1 to 3I-4 will be described in detail), and the locking slider 324 can be pushed through the second engaging window 322 on the front engaging plane 308, so as to be engaged in the rear body cover 108 The rear side of the front body cover 107 is engaged in the groove 313 on the plane 311 (see Figure 3I-1 for details), so that the front body cover 107 and the rear body cover 108 are locked, so that the front body cover 107 and rear vehicle body cover 108 are fixed completely, can not move up and down relatively between the two. Simultaneously, the locking slider 324 is engaged in the groove 313 and can also realize the connection of the front vehicle body wire connection device 201 and the rear vehicle body wire connection device 221, thereby realizing the electrical connection between the front vehicle body 101 and the rear vehicle body 102. One point will be detailed later.

The drive shaft 330 passes through the window cover plate 150 of the locking mechanism accommodation cavity 310 and is connected with the trigger mechanism 130, and the drive shaft 330 is driven to rotate by the trigger mechanism 130 to drive the locking pressing block 314 and the locking slider 324 to lock and release The front vehicle body cover 107, and the connection and separation of the front vehicle body wire connection device 201 and the rear vehicle body wire connection device 221.

A cam mechanism is provided on the driving shaft 330 for driving the locking pressing block 314 and the locking sliding block 324 to move. 3E-1 to 3E-3 are multi-angle stereoscopic structural views of the drive shaft 330 . As shown in FIGS. 3E-1 to 3E-3 , the cam mechanism includes a driving surface 332 and a claw 331 . The driving surface 332 cooperates with the locking pressing block 314, and is used to drive the locking pressing block 314 to move with the rotation of the drive shaft 330; The movement of the slider 324 will be described in detail below.

The distal end 305 of the drive shaft 330 is inserted into the hole (not shown) on the inner wall of the locking mechanism cavity 310, the proximal end 307 of the drive shaft 330 passes through the through hole 152 (as shown in Figure 3G) on the window cover plate 150 and It is connected with the pull mechanism 130, so that when the pull mechanism 130 is pulled to rotate, the drive shaft 330 rotates with the pull mechanism 130.

The locking pressing block 314 and the locking slider 324 are described below in conjunction with the accompanying drawings 3B-1, 3B-2, 3D-1, 3D-2, 3D-3 and 3G. Among them, Fig. 3D-1 is a three-dimensional structure diagram of the locking slider of the present invention, Fig. 3D-2 is a sectional view of the internal structure of the locking slider of the present invention, Fig. 3D-3 is an exploded structural diagram of the locking slider of the present invention, and Fig. 3G is an exploded view of the structure of the support rod shown in FIG. 3B-1 of the present invention.

As shown in the figure (especially Fig. 3G), the locking pressing block 314 is a cubic pendulum block, the top 315 of the locking pressing block 314 is rotatably sleeved on a fixed shaft 317, and the two ends of the fixed shaft 317 are fixed On the inner wall of the cavity 310 of the locking mechanism, the locking pressing block 314 can swing around the fixed shaft 317 at a certain angle. The side of the locking pressure block 314 facing the rear body cover 108 is a locking plane 316, and the back side of the locking plane 316 is in contact with the driving surface 332 (see Figs. When the rotation direction (such as clockwise) turns, a clockwise rotation thrust is provided to the locking pressing block 314 to push the locking pressing block 314 toward the rear engaging plane of the front body cover 107 located in the rear body cover 108 311 swings and passes through the first engaging window 318 to the locked position (as shown in Figure 3B-2), thereby pressing the rear side engaging plane 311 through the locking pressing block 314 to prevent the front body cover 107 and Relative up and down movement between the rear body covers 108 and/or sideways sway between the front body covers 107 and the rear body covers 108 . And when the driving shaft 330 rotates in the second rotation direction (eg, counterclockwise), the locking pressing piece 314 is released, so that the locking pressing piece 314 can withdraw from the first engaging window 318 .

The fixed shaft 317 is also sleeved with a return spring 319 (see FIG. 3G ). The return spring 319 is a torsion spring, one end is fixed on the inner wall of the cavity 310 of the locking mechanism, and the other end is fixed on the locking pressure block 314 . The return spring 319 is used to provide a torque that makes the locking pressure piece 314 swing counterclockwise, so that the locking pressure piece 314 swings away from the rear engaging plane 311 of the front body cover 107 to the release position ( As shown in Figure 3B-1). In addition, when the drive shaft 330 is at the release position, the torsion of the return spring 319 prevents the locking pressing piece 314 from swinging freely, thereby avoiding interference with other components.

The locking slider 324 is a slidable contact block, which can move between a locked position and a released position along the left and right directions in the figure. As shown in FIG. 3D-1 to FIG. 3D-3 , the locking slider 324 has a roughly cubic structure and is hollow inside.

When the drive shaft 330 rotates in the first rotation direction (such as clockwise), the claw 331 pushes the locking slider 324 through the second engaging window 322 on the front engaging plane 308 to engage on the front body The rear side of the sleeve 107 engages with the groove 313 on the plane 311 (see FIG. 3I-1 for details), so that the front body cover 107 and the rear body cover 108 cannot move up and down relative to each other. And when the driving shaft 330 rotates in the second rotation direction (eg, counterclockwise), the claw 331 shifts the locking slider 324 to the release position, so that the locking pressing block 314 can exit from the second engaging window 322 .

As shown in FIG. 3D-3 , the head of the locking slider 324 accommodates a pulley terminal block 385 in which a plurality of front contact pins 386 are integrated, and the pulley terminal block 385 has a rear contact plane 390 . Front contact pins 386 are resiliently mounted to ensure effective electrical contact. The front end of the front contact pin 386 protrudes outside the rear vehicle contact plane 390 . The rear ends of the front contact pins 386 are connected to bundles of rear wires 231, as shown in FIG. 3D-2. The trolley terminal block 385 with the front contact pins 386 constitutes the rear body wire connecting means 221 described above. The rear vehicle body wire connecting device 221 is accommodated by the locking slider 324 and moves with the locking slider 324 , so as to realize the connection and separation of the rear vehicle body wire connecting device 221 and the front vehicle body wire connecting device 201 . The two sides of the locking slider 324 are also provided with the same guide ribs 327, 329, as shown in FIG. 3D-2. The guide rib 327 is inserted into the inner wall of the locking mechanism cavity 310 and the guide groove 337 provided on the window cover plate 150 (see the guide groove 337 on the window cover plate 150 shown in FIG. 3G, the guide groove on the inner wall is not shown), The locking slider 324 can be smoothly and accurately inserted into the groove of the connection plate 361 when sliding, so as to realize the contact connection between the rear vehicle body wire connection device 221 and the front vehicle body wire connection device 201 .

According to the embodiment of the present invention, a bushing is also provided between the front body cover 107 and the rear car body cover 108 , and FIG. 3F shows a three-dimensional structural view of the bushing of the present invention.
