Description

suspended gyro

technical field

The invention relates to the field of toy tops, in particular to a suspended top.

Background technique

A rigid body that rotates at a high speed around a fulcrum is called a top, and the top is one of the earliest entertainment tools in China. The upper part of the shape is round and the lower part is sharp. In the past, they were mostly made of wood, but in modern times they are mostly made of plastic or iron. When playing, it can be wrapped with a rope, and the rope can be pulled hard to make it rotate upright. Or use the elastic force of the mainspring to rotate. The traditional ancient spinning top is roughly in the shape of an inverted cone made of wood or iron, and is played with a whip.

However, the top has the following disadvantages: the tip of the top is relatively sharp. If the tip of the top touches the skin of a child when it rotates at high speed, it may scratch the skin and there is a certain danger. Therefore, this traditional top is not suitable for younger children to play with. .

Secondly, the existing spinning top playing method is also relatively single, which does not solve the single problem of playing method. At present, the Chinese patent application number CN95233271.X discloses a flying top. On the basis of the existing gyroscope, add a paddle disc with propeller blades. There is an opening on the paddle disc, and the flying gyro will fly off the ground when it rotates. It is very entertaining and interesting. The problem of spinning without being able to fly off the ground. The utility model has the effects of simple structure, beautiful appearance and practicality, and is a good tool for fitness and entertainment.

There is following defect in above-mentioned gyroscope:

1. The power input is manually input. When the gyro is out of the hand, there is no longer a steady stream of power input. Immediately after the gyro flies, the speed becomes low due to the lack of power, and it starts to fall. It is difficult to continue to rotate, and the user needs to frequently turn.

2. The gyro is integral, and it rotates at high speed and flies in the air, which can easily cause the head or face of children to be accidentally injured by the high-speed gyro tip.

The object of the present invention is to provide a suspended gyroscope, the flywheel of the counterweight is arranged in the housing, the housing and the blades are light, and the gyroscope can be stopped quickly after it touches the child's skin, reducing further damage and improving safety; secondly, the gyroscope With a drive and power supply, it can be turned all the time; the blades can realize gyroscopic flight and add fun.

In order to achieve the purpose of the above invention, the present invention adopts the following technical solutions: a suspended gyroscope, including a housing and a flywheel rotatable in the housing, the bottom of the housing is provided with a top for supporting the rotation of the gyroscope, and the housing covers On the outer surface of the flywheel, the housing is provided with an opening for insertion of the rack, and the flywheel is provided with a first gear that cooperates with the rack to pull the flywheel to rotate horizontally, and a supporting plate is fixed inside the housing. The flywheel is placed above the supporting plate, and the flywheel is attached to the upper surface of the supporting plate with gravity, and the supporting plate and the housing rotate synchronously; the housing is also provided with blades that rotate to make the gyroscope fly, and the blades rotate synchronously with the housing.

The suspended gyroscope also includes a power supply, a centrifugal trigger switch and a driver for continuously rotating the flywheel. The centrifugal trigger switch is connected to the driver and the power supply. By adding a power supply, a driver and a centrifugal trigger switch, the flywheel can continuously obtain the kinetic energy of the driver. The gyroscope can rotate all the time. The centrifugal trigger switch mentioned in the present invention is triggered according to the size of the centrifugal force. When the rotating speed is high, the switch is connected, and when the rotating speed is low, the switch is disconnected. The centrifugal trigger switch includes:

- fixed contacts for connecting the power supply and the driver;

- The movable contact can contact the fixed contact to energize the driver when the centrifugal force increases, and the movable contact is a conductive part;

- a return element that separates the movable contact from the fixed contact when the centrifugal force is low;

-Movable cavity for the movable contact to move and contact or move away from the fixed contact.

The above-mentioned supporting plate can be integrated with the housing, as long as the supporting plate and the housing are fixed to drive the housing to rotate. For the convenience of manufacturing the present invention, the housing includes an upper cover and a base, and the supporting plate is sandwiched and fixed. Between the upper cover and the base, the flywheel is arranged between the supporting plate and the upper cover, and the opening is located on the base.

Preferably, the blades are arranged inside the casing, and the outside of the blades includes a rotating shaft, the rotating shaft is pivotally connected to the inside of the casing close to the outer circumference of the gyroscope, and the casing is provided with slots for the blades to rotate out of the casing with the centrifugal rotation of the gyro , the addition of slots allows the blades to be stored in the housing without occupying a volume, reducing the space, and secondly improving the activities of the gyroscope and increasing the fun.

Preferably, the rotating shaft is provided with a torsion spring for the blades to be reset and folded to the inside of the casing, through the torsion spring.

Preferably, both the blade and the flywheel are located in the upper cover, and the blade includes an outer part, a transition part and an inner part, the outer part is located at the outer edge of the housing, the inner part is located inside the housing, and the transition part is The outer part and the inner part are connected, the transition part is located on the outer peripheral side of the flywheel, and the inner part is located on the upper surface of the flywheel with a gap left. The transition part and the inner part together constitute a housing chamber for accommodating the flywheel.

Preferably, the transition portion is arranged obliquely, and the inclination direction of the transition portion is the same as the inclination direction of the outer sheet portion and the inner sheet portion.

The above-mentioned reset member can use springs, rubber and other elastic members, but the above-mentioned elastic members have certain aging and rust phenomena, and are relatively large in size. Therefore, it is preferred that the reset member is a permanent magnet that attracts the movable contact. The movable contact is a conductive magnetic attraction matched with a permanent magnet, which has no aging phenomenon and is small in size, so that the centrifugal trigger switch can be further reduced in size.

Since the attractive force between the magnetic parts produces an exponential change according to the distance, the suction force is the largest when fully sucked and is difficult to control. Therefore, it is preferred in the present invention that an increase of two The distance between them is used to reduce the partition wall of attraction.

Preferably, the fixed contact is divided into a first contact and a second contact, the movable cavity is a channel for the movable contact to move linearly, and the movable cavity faces the middle of the first contact and the second contact.

Compared with the prior art, the suspended gyroscope adopting the above technical solution has the following beneficial effects:

1. Drive the flywheel to rotate at high speed through the rack, use the gravity of the flywheel to generate friction with the supporting plate, and then indirectly drive the rotation of the entire gyroscope shell. Since the entire high-speed rotating flywheel is set inside the shell, the shell wraps the flywheel , It can effectively prevent the high-speed rotating flywheel from scratching or scratching children, and plays a good protective role.

2. The flywheel in the casing is used as a counterweight. After being pulled by the rack, the flywheel is still in the state of high-speed rotation. Even after the casing is fixed, the flywheel is still in the state of rotation. Rotate, and finally achieve the synchronous rotation of the housing and the flywheel; therefore, the gyroscope in the present invention will not directly fall to the ground and stop rotating like a traditional gyroscope when it hits an obstacle.

3. Due to the power supply and driving device, when the centrifugal trigger switch is triggered by the high-speed rotating shell, the driving device is energized to make the flywheel rotate rapidly, and the top can rotate until the user manually stops it.

4. Blades are added outside the casing. When the rotation speed of the casing is large enough, the upward driving force can be generated through the blades to lift the entire gyro off the ground or reduce the gravity of the gyro through the lifting force, reducing the distance between the gyro and the ground. The friction, the resistance to be overcome by turning the gyroscope is reduced, and the driver load is reduced.

5. The shell and blades are much lighter than the flywheel, so it is easier to stop the shell of the gyro in an emergency. When the gyro flies off the ground, even if the tip of the gyro touches the skin, the shell will stop rotating quickly, and the flywheel will not affect it. harm the user.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

Example 1:

The suspended gyroscope shown in FIGS. 1 to 3 includes, from top to bottom, a cover 7 , an upper cover 1 , blades 9 , a flywheel 4 , a supporting plate 3 and a base 2 .

In this embodiment, the entire flywheel 4 and blades 9 are inside the upper cover 1, and the flywheel 4 is driven to rotate by the rack, and then the friction contact between the flywheel 4 and the supporting plate 3 is used to drive the top shell to rotate.

Wherein the quantity of speed-up gear 5 can be single, also can be multiple.

A centrifugal trigger switch 6, a driver and a power supply are added to the top of the upper cover 1, and the centrifugal trigger switch 6 is triggered by the high-speed rotating gyroscope, so that the driver 8 is energized, and the driver 8 further keeps the flywheel 4 in a rotating state, and the whole gyroscope keeps rotating until the centrifugal Trigger switch 6 is disconnected, and the top just stops rotating.

The supporting plate 3 is interposed and fixed between the upper cover 1 and the base 2 , the base 2 is provided with an opening 20 , and the rack can go deep into the opening 20 and be pulled to rotate the acceleration gear 5 .

Flywheel 4 middle part is provided with a rotating shaft, and rotating shaft and flywheel 4 are fixed and synchronously rotated, and the bottom of flywheel 4 is provided with first gear 40, and first gear 40 cooperates with acceleration gear 5, can drive the rotation of whole flywheel fast. The inner wall surface of the base 2 is provided with a rotating shaft seat for the rotating shaft of the flywheel 4 to be fixed and rotated, and the rotating shaft seat reduces the friction of the rotating shaft.

As shown in Figure 8, the top of flywheel 4 is provided with second gear 41, and second gear 41 is fixed with the end of rotating shaft, and rotating shaft penetrates loam cake 1, and second gear 41 is positioned at the top of loam cake 1.

The top of the upper cover is provided with a centrifugal trigger switch 6, a battery holder 11 and a motor holder 8, a battery 9 is installed in the battery holder, a driver 8 is fixed in the motor holder, the driver 8 is driven by a micro motor, and the driver 8 is provided with a drive gear 80, The driving gear 80 cooperates with the second gear 41 .

As shown in FIG. 9 , the centrifugal trigger switch 6 includes a fixed contact 64 , a movable contact 61 , a magnet 60 , a partition wall 63 and a movable cavity 62 .

The fixed contact 64 is divided into a first contact 640 and a second contact 641. The movable cavity 62 is a channel for the linear reciprocating movement of the movable contact 61. One end of the channel is located between the first contact and the second contact. One end is located on the magnet 60 .

The movable contact 61 adopts a steel ball or a cylindrical steel block, and the partition wall 63 is used to reduce the attraction force of the magnet 60 to the movable contact 61 to facilitate centrifugal triggering.

When the top rotates, the centrifugal force is large enough to make the movable contact 61 break away from the attraction of the magnet 60, and the movable contact 61 is thrown between the first contact 640 and the second contact 641 by the centrifugal inertia, so that the two contacts are connected. form a loop. And when the rotating speed of the gyroscope decreased, the suction force of the magnet 60 was greater than the centrifugal force, the movable contact 61 was sucked back to its original position, and the fixed contact 64 was in the disconnected state.

The blade 9 is arranged on the inside of the housing, and the outside of the blade 9 includes a rotating shaft 90. The rotating shaft 90 is provided with a torsion spring for the blade 9 to be reset and folded to the inside of the housing. There is a slot 12 for the blade 9 to turn out from the housing with the centrifugal rotation of the gyroscope.

When the gyro rotates at low speed, the blade 9 cannot overcome the elastic force of the torsion spring due to the small centrifugal force, so the blade 9 stays in the upper cover 1, and when the gyro rotates at a high speed, the blade 9 is thrown from the inside of the upper cover 1 due to the centrifugal force. Then, due to the inclined setting of the blades 9, the blades 9 are subjected to the resistance of the wind all the time, so that the blades 9 are firmly against the groove bottom of the slot 12, maintaining an unfolded state.

As shown in Figures 4 to 7, both the blade 9 and the flywheel are located in the upper cover, and the blade 9 includes an outer part 91, a transition part 92 and an inner part 93, the outer part 91 is located at the outer edge of the housing, and the inner part The part 93 is located inside the housing, the transition part 92 connects the outer part 91 and the inner part 93, the transition part 92 is located on the outer peripheral side of the flywheel, the inner part 93 is located on the upper surface of the flywheel and leaves a gap, the outer part 91 and the inner The angles of inclination of the blades 93 are kept the same, the purpose is that the upward force generated when the blade 9 cuts the air is uniform, and if the angles are different, the generated force is not uniform, which may easily cause the blade to vibrate.

As shown in Fig. 7, the transition part 92 and the inner piece part 93 jointly constitute a housing cavity 94 for accommodating the flywheel, the housing cavity 94 is located below the inner piece part 93, and the outer piece part 91 and the inner piece part 93 have the same inclination direction and angle The transition portion 92 is arranged obliquely, and the inclination direction of the transition portion 92 is the same as the inclination direction of the outer sheet portion 91 and the inner sheet portion 93 .

One of the functions of the transition portion 92 is to raise the inner sheet portion 93 so that the inner sheet portion 93 can be inserted into the space of the upper cover 1 on the top of the flywheel 4; 93 is the same, in order not to disturb the airflow, and can not produce reverse resistance; moreover, the angle of inclination of the transition part 92 is smaller than the other two, the purpose is to slightly increase the resistance of the blade, to overcome the elastic force of the torsion spring, and to avoid The rebound of the torsion spring.

Therefore, the process used in this embodiment is as follows:

1. Manual rotation of the flywheel: insert the rack into the opening 20 of the base 2, pull the rack to drive the acceleration gear 5 to rotate, and then the first gear 40 follows the rotation, and the flywheel 4 starts to rotate at high speed;

2. Housing rotation: the rotation of the flywheel 4 drives the supporting plate 3 to rotate, and then the housing also rotates accordingly;

3. Switch trigger: when the rotation speed of the housing reaches a certain value, the centrifugal force of the movable contact 61 is greater than the attraction force of the magnet 60, so that the movable contact 61 moves to the end of the fixed contact 64 through the movable cavity 62, so that the first contact 640—the movable contact 61—the second contact 641 is connected, and the power supply 9 is connected with the micro motor 8.

4. Electric rotation: the micro-motor 8 is supplied with power and rotates rapidly, drives the flywheel 4 to continuously rotate rapidly through the driving gear 80 and the second gear 41, and keeps the movable contact 61 pressed against the first contact 640 and the second contact 641 In between, keep the motor powered.

6. Blade unfolding: the rotational speed of the gyro is high enough, so that the blade 9 is thrown out from the slot 12 by the centrifugal force inside the upper cover 1, and the blade 9 overcomes the spring force of the torsion spring and rotates out of the slot 12 along the rotating shaft 90, and leans against the slot 12 groove bottom. During the subsequent rotation, since the blade 9 is subjected to air resistance, the resistance is mainly generated by the transition portion 92, so that the blade 9 is firmly fixed at the bottom of the slot.

7. Gyro suspension: Since the inner piece 93 and the outer piece 91 of the blade 9 rotate with the gyro at high speed, the flowing air flow will generate upward buoyancy to the blade, lifting the whole gyro upward, which can reduce the gravity of the whole gyro or even Make the top fly off the ground.

5. Stall: By reducing the rotational speed of the gyro shell, the centrifugal force received by the movable contact 61 in the centrifugal trigger switch 6 is less than the attraction force of the magnet 60, and the movable contact 61 is sucked back to its original position by the magnet 60, so that the fixed contact The micromotor 8 loses power supply, and the flywheel stops after a period of rotation by inertia (or a delay switch is added to automatically disconnect the driver and power supply within a period of time after the centrifugal trigger switch 6 is started, so that the gyro stops rotating) .

This embodiment has the following advantages:

1. The gyro can rotate continuously through the battery and motor without frequent power supply.

2. In addition to being connected with the motor, the centrifugal trigger switch 6 can be opened to add some light-emitting components and sound-generating components, so that it can emit sound effects and light after being connected to the power supply, so as to improve the interest of the toy top.

3. The flywheel for the counterweight is placed inside the lightweight shell, and when the gyro touches the child's skin or other objects, it can stop quickly and reduce the risk.

4. The gyro is lifted by the blades, the gravity becomes lower, the frictional resistance becomes smaller, and the motor load is smaller.

Example 2:

As shown in Figure 10 and Figure 11, it is a simplified version of Embodiment 1, wherein the blade 9 is directly fixed on the shell of the gyroscope, the shell is divided into an upper cover 1 and a base 2, and the supporting plate 3 is separately arranged. The plate 3 can be fixed in front of the upper cover 1 and the base 2 by means of bolts, glue, etc., the flywheel 4 is placed in the upper cover, and the bottom of the flywheel contacts the supporting plate 3 .

The top of loam cake 1 is also provided with battery holder 11 and motor holder 10, batteries are placed in the battery holder 11, and micromotor is fixed in the motor holder 10. The output shaft of the motor is directly connected with the rotating shaft of the flywheel, and the top of the loam cake 1 is also provided with the same centrifugal trigger switch 6 as in the first embodiment.

Compared with Embodiment 1, this embodiment has the advantages of: while realizing automatic power supply and self-rotating flight of the gyro, its safety is guaranteed, and the activities of the blades are reduced to reduce the manufacturing cost.

The above description makes the preferred implementation of the present invention, for those skilled in the art, without departing from the principle of the present invention, some modifications and improvements can be made, which should also be regarded as the protection scope of the present invention.
