Description

Technical Field

[0001] This utility model relates to the field of toy vehicles, and more particularly to a toy stunt vehicle. Background Technology

[0002] Toy cars are a popular category of toys. Ordinary toy cars mostly attract users' attention with their vehicle design, but their fun factor is relatively average. To enhance the fun of playing, toy stunt cars have appeared on the market, which can achieve functions such as standing up and walking, and rotating, attracting consumers' attention. When ordinary stunt cars stand up (two front wheels or two rear wheels lift up), they usually maintain the stability of standing up through pulleys on the vehicle body, allowing the toy car to move forward / backward in an upright position. However, when stunt cars rotate in an upright position, traditional pulleys can only provide forward and backward sliding support and cannot be well adapted to the upright rotation of stunt cars, making the vehicles prone to tipping over. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a toy stunt vehicle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A toy stunt car, comprising a body, a drive unit, and a support part, wherein the support part is disposed on the front side and / or rear side of the body, the support part comprising a support frame, a swing frame, and a ball bearing, wherein the swing frame is provided with a ball bearing mounting cavity and a ball bearing opening, the ball bearing is placed in the ball bearing mounting cavity, the ball bearing opening is located on the side of the ball bearing mounting cavity away from the body, the diameter of the ball bearing opening is smaller than the diameter of the ball bearing, and a portion of the ball bearing passes through the ball bearing opening and is located outside the swing frame.

[0005] Furthermore, a spring is provided in the ball bearing mounting cavity, and the spring is located on the side of the ball bearing away from the ball bearing opening.

[0006] Furthermore, the swing frame is rotatably mounted on the support frame, and the swing frame has a through mounting port in the middle. A swing shaft is provided in the middle of the mounting port, and the swing frame is mounted on the mounting port. A swing shaft channel is provided in the middle of the swing frame, and the swing shaft passes through the swing shaft channel. The swing frame has two ball bearing mounting cavities, which are symmetrically arranged on both sides of the swing shaft channel.

[0007] Furthermore, the swing frame consists of a front swing frame and a rear swing frame, with the ball bearing port located on the front swing frame.

[0008] Furthermore, a limit plate is installed on the support frame on the rear side of the swing frame.

[0009] Furthermore, the swing frame is tilted from the upper outer side to the lower inner side.

[0010] Furthermore, the drive device includes two drive motors and two sets of gears. The output shaft of one drive motor faces the left side of the vehicle body, and the output shaft of the other drive motor faces the right side of the vehicle body. The two sets of gears are respectively located on the left and right sides of the vehicle body. The output shaft of the drive motor is provided with teeth, and each of the two sets of gears meshes with the teeth on the output shaft of the adjacent drive motor.

[0011] Furthermore, the vehicle body is also equipped with four wheels, and wheel axles are provided on the inner side of each wheel, with the wheel axles fixed to the end gear of the gear set.

[0012] Furthermore, the gear set consists of an odd number of symmetrically arranged gears, with the middle gear meshing with the teeth on the output shaft of the drive motor.

[0013] The beneficial effects of this invention are as follows: The support section contains freely rolling ball bearings. When the stunt vehicle is in an upright rotating state, the ball bearings roll synchronously with the vehicle's rotation direction, forming continuous dynamic support. Rolling friction replaces sliding friction, ensuring that the support point always maintains the optimal contact angle with the rotation trajectory, significantly reducing the risk of rollover. Furthermore, the swing frame is symmetrically equipped with two ball bearing mounting cavities and ball bearings. During upright rotation, the inner ball bearing, being closer to the center of rotation, forms the main support, while the outer ball bearing plays an auxiliary stabilizing role, enabling the stunt vehicle to maintain excellent anti-rollover capability during rotation, further improving stability.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Example 1: A toy stunt car includes a body 1, a drive unit, and a support 2. The support 2 is located on the front and rear sides of the body 1, enabling the stunt car to lift its front wheels and stand upright, as well as lift its rear wheels. The support 2 includes a support frame 21, a swing frame 22, and ball bearings 3. The swing frame 22 is provided with a ball bearing mounting cavity 223 and a ball bearing opening 224. The ball bearings 3 are placed in the ball bearing mounting cavity 223. The ball bearing opening 224 is located on the side of the ball bearing mounting cavity 223 away from the body 1. The diameter of the ball bearing opening 224 is smaller than the diameter of the ball bearings 3. A portion of the ball bearings 3 passes through the ball bearing opening 224 and is located outside the swing frame 22. When the stunt car is in an upright rotating state, the ball bearings 3 located outside the ball bearing opening 224 can roll synchronously with the direction of vehicle rotation, forming continuous dynamic support and significantly reducing the risk of tipping over. When the stunt car is in a three-dimensional forward or backward state, the ball bearings can also provide forward and backward rolling support capabilities no less than those of a pulley.

[0022] Furthermore, a spring 5 is provided in the ball bearing mounting cavity 223. The spring 5 is located on the side of the ball bearing 3 away from the ball bearing opening 2. The spring 5 can provide cushioning when the stunt vehicle stands up, walks, and rotates.
