[0002] Existing toy cars generally have an electric travel function, and can also be controlled by a remote control to achieve forward, backward, and turning. However, the body of such existing toy cars can only rotate and deflect, and cannot move up and down or swing left and right relative to the body. Therefore, when turning, the body overcomes the centrifugal force and balances itself, so when the speed is fast, the toy car is prone to rollover. That is, the existing toy cars have the problem of unstable steering. Therefore, in order to reduce the occurrence of rollover when turning, the existing toy cars generally limit the speed of the toy cars, resulting in the speed of the existing toy cars being not fast.

Furthermore, in order to ensure that the steering of the two front wheels 2 is synchronous and consistent, in some embodiments, the connecting member 3 further includes a steering linkage 33, such as Figure 3 As shown, strip grooves 331 are provided at both ends of the steering linkage 33, and the steering linkage 33 can be movably installed in the shell 31 along the width direction of the vehicle body 1; the rotating connection member 32 is correspondingly provided with a first convex shaft 323 and a second convex shaft 324 with the same direction, and the first convex shaft 323 is rotatably connected to the shell 31, so that the rotating connection member 32 can rotate around the first convex shaft 323, that is, the front wheel 2 can turn around the first convex shaft 323; the second convex shaft 324 extends into the strip groove 331 to realize that the two rotating connections 32 are respectively connected to the steering linkage 33, so when one of the front wheels 2 turns, the front wheel 2 will pull / push the steering linkage 33, causing the steering linkage 33 to be displaced, thereby driving the other front wheel 2 to turn synchronously.

[0050] The connection between the rear wheel 4 and the vehicle body 1 of the utility model can be a connection between a slide groove and a slider, or a connection between the rear wheel 4 and the vehicle body 1 through a pin 5, one end of the pin 5 is provided with a rear shaft 51 protruding in its radial direction, the rear wheel 4 is connected to the rear shaft 51 so that the rear wheel 4 can rotate around the axis of the rear shaft 51, and the specific connection method between the rear wheel 4 and the rear shaft 51 can refer to the connection method between the front wheel 2 and the front shaft 321; correspondingly, the vehicle body 1 is provided with a socket 16 extending from the bottom to the top for the pin 5 to be inserted, and the pin 5 can move along the depth direction of the socket 16 after being inserted into the socket 16.

[0051] In order to prevent the rear wheel 4 from rotating randomly with the latch 5, thereby affecting the normal running of the toy car, Figure 4 In the example shown, the latch 5 of the example is provided with a convex wing 52 along its radial direction and perpendicular to the axial direction of the rear shaft 51, and the socket 16 is provided with a groove 17 at a corresponding position. After the latch 5 is inserted into the socket 16, the convex wing 52 cooperates with the groove 17. At this time, the latch 5 cannot rotate in the socket 16 and can only move up and down. Therefore, the rear wheel 4 is fixed in the front and rear direction of the toy car and will not deviate from the direction at will.

[0052] In order to prevent the latch 5 from falling out of the socket 16, thereby causing the rear wheel 4 to detach from the vehicle body 1, the latch 5 of the utility model can be designed as a T-shaped pin 313, or it can be: an opening is correspondingly provided at the bottom of the socket 16, and the part of the latch 5 extending into the socket 16 passes through the opening; a screw hole is opened in the middle of the end face of the part of the latch 5 extending out of the opening, and a bolt with a nut and a nut with a diameter larger than the opening diameter is screwed into the screw hole, so that the latch 5 will be restricted by the nut and will not fall out of the socket 16.

The multi-directional wheel set 6 drives the vehicle body 1 to move and / or turn under the drive of the driving device 7. The multi-directional wheel set 6 includes a pair of rollers 61 and a steering wheel 62 connected to the rollers 61. The rotation of the rollers 61 can drive the vehicle body 1 to move, and the front wheels 2 and the rear wheels 4 of the toy car are both driven wheels; the steering wheel 62 deflects and the rollers 61 rotate to drive the vehicle body 1 to turn. When turning, the front wheel 2 will also be driven to deflect around the first convex shaft 323, thereby assisting the steering wheel 62 to achieve smooth turning of the toy car. The driving device 7 of the example can control the rotation of the rollers 61 and the deflection of the steering wheel 62 respectively.

[0054] Specifically, the driving device 7 includes two motors, wherein the first motor 701 is used to drive the roller 61 to rotate, and the second motor 702 is used to drive the steering wheel 62 to deflect. The shaft gear of the first motor 701 is meshed with the first gear plate 703, the bottom of the first gear plate 703 is integrally connected with a first gear 704, the first gear 704 is meshed with a second gear 705, the upper end of the axle of the second gear 705 is connected with a third gear 706, the third gear 706 is meshed with a second gear plate 707 sleeved on the roller shaft 63, so through a series of gear transmission, the first motor 701 finally drives the roller 61 to rotate.

[0058] The front wheel group of this embodiment includes two front wheels 2 and a connecting member 3 connected between the two front wheels 2. The middle part of the connecting member 3 is rotatably connected to the bottom of the vehicle body 1, and the direction of its rotation axis is consistent with the length direction of the vehicle body 1, thereby realizing that the two front wheels 2 of the front wheel group can swing up and down, that is, when the left front wheel 2 rotates downward around the axis, the right front wheel 2 rotates upward around the axis relatively, and when the left front wheel 2 rotates upward around the axis, the right front wheel 2 rotates downward around the axis relatively. The connecting member 3 includes a shell 31, a rotating connecting member 32 and a steering linkage 33.

A through hole 21 is opened in the middle of the front wheel 2. After the front shaft 321 is inserted into the through hole 21 of the front wheel 2, the edge of the threaded hole 322 is flush with the edge of the through hole 21, and then a bolt (not shown in the figure) passes through the through hole 21 and is screwed into the threaded hole 322, thereby realizing a rotatable connection between the front shaft 321 and the front wheel 2. Figure 2 As shown, a circular through groove 311 is formed on the shell 31, and the circular through groove 311 runs through the middle of the shell 31, and a countersunk hole 312 with a diameter larger than the circular through groove 311 is formed on one side of the shell 31; a recess 14 is formed at the bottom of the car body 1 for the shell 31 to be placed, and a pin hole 15 is coaxially formed at the other side of the bottom of the car body 1 away from the side where the countersunk hole 312 is located, corresponding to the circular through groove 311.

After installation, the nail head of the pin 313 is just in the countersunk hole 312. After connection, the shell 31 can swing up and down around the two ends of the pin 313 in the recess 14, thereby driving the front wheel 2 to swing up and down.

[0059] The rear wheel assembly of this embodiment includes two independent rear wheels 4, each of which is movably connected to the vehicle body 1, and its moving direction is consistent with the height direction of the vehicle body 1, that is, the rear wheel assembly can move up and down, so the vehicle body 1 can swing up and down and fine-tune its position up and down relative to the wheel. Specifically, the rear wheel 4 is connected to the vehicle body 1 through a latch 5, and one end of the latch 5 is provided with a rear shaft 51 protruding in its radial direction. The rear wheel 4 is connected to the rear shaft 51 so that the rear wheel 4 can rotate around the axis of the rear shaft 51. The specific connection method between the rear wheel 4 and the rear shaft 51 can refer to the connection method between the front wheel 2 and the front shaft 321; correspondingly, the vehicle body 1 is provided with a socket 16 extending from the bottom to the top for the latch 5 to be inserted into, and the latch 5 can move along the depth direction of the socket 16 after being inserted into the socket 16. As shown Figure 4 As shown, the bolt 5 is provided with a convex wing 52 along its radial direction which is perpendicular to the axial direction of the rear shaft 51, and the socket 16 is provided with a groove 17 at a corresponding position. After the bolt 5 is inserted into the socket 16, the convex wing 52 matches with the groove 17, and the bolt 5 cannot rotate in the socket 16, and can only move up and down, so the rear wheel 4 is fixed to face the front and rear direction of the toy car, and will not deflect in any direction, so it will not affect the normal running of the toy car.

The upper end of the axle of the second gear 705 is connected to the third gear 706, and the third gear 706 meshes with the second gear plate 707 sleeved on the roller shaft 63. Therefore, through a series of gear transmission, the first motor 701 finally drives the roller 61 to rotate.

A light-emitting device is provided inside the car shell 12, and the light-emitting device of this embodiment is a color light-emitting light strip (not shown in the figure), which is installed on the inner side of the transparent or translucent piece 8. When the light-emitting device is powered on, the light is transmitted from the transparent or translucent piece 8, thereby making the toy car cooler and more attractive.

[0062] The front wheel group of this embodiment can swing up and down, and the rear wheel group can move up and down, so the body 1 can swing up and down and fine-tune the position up and down relative to the wheel. Therefore, when the toy car turns, the toy car will balance itself under the action of centrifugal force, that is, at this time, the body 1 will tilt relative to the wheel, and its tilting direction is the inner side direction of the arc of the turn, similar to the tilting of the body when turning in a motorcycle racing competition. By tilting the body 1, the center of gravity can be better lowered, and better grip can be obtained, ensuring that the toy car will not roll over when turning sharply, effectively solving the problem of unstable steering in existing toy cars and the problem that the speed of the toy car cannot be set too fast. Moreover, after the turning action is completed, the centrifugal force disappears, so the body 1 can return to a normal horizontal state. In addition, the car shell 12 is provided with a cool light effect, so that the toy car can be favored and loved by more children.
