Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, and in particular to a toy car. Background Technology

[0002] Traditional toy cars are small in size, with limited space for shock absorption mechanisms, making it difficult to implement complex buffer structures (such as dampers), thus sacrificing stability. Furthermore, most use simple springs or rubber pads, resulting in poor performance under high-frequency vibrations or large impacts. They also cannot dynamically adjust according to steering speed or road surface bumps, and are prone to overshoot or rebound during high-speed turns. Therefore, we propose a new type of toy car. Utility Model Content

[0003] The main purpose of this utility model is to provide a toy car.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A toy car includes a main frame, with a multi-axis synchronous motion assembly, a sub-frame, a middle frame, and a front wheel steering stabilization assembly mounted on the bottom of the main frame. The multi-axis synchronous motion assembly comprises four sets. The sub-frame is rotatably connected to both ends of the main frame, and the middle frame is fixedly connected to the bottom of the main frame. Front wheel steering stabilization assemblies are provided on both sides of the sub-frame. Each multi-axis synchronous motion assembly includes an end axle connecting rod and a rotating column. The rotating column is fixedly connected to both ends of the end axle connecting rod. One rotating column is rotatably connected to the middle frame, and the other rotating column is rotatably connected to the sub-frame.

[0005] A further improvement of this utility model is that the intermediate frame is rotatably connected to a main universal joint shaft, one end of which is fixedly connected to one of the rotating columns, and the main universal joint shaft is used for universal transmission between one of the rotating columns and the intermediate frame.

[0006] A further improvement of this utility model is that the sub-frame is rotatably connected to a sub-universal adapter shaft, the sub-universal adapter shaft is fixedly connected to another rotating column head, and the sub-universal adapter shaft is used for universal transmission between the other rotating column head and the sub-frame.

[0007] A further improvement of this utility model is that the front wheel steering stability assembly includes a transmission bracket, a front axle connecting rod, and a lateral movable shaft. The transmission bracket is rotatably connected to the sub-frame, the front axle connecting rod is rotatably connected to the transmission bracket, the lateral movable shaft is rotatably connected to the front axle connecting rod, and the lateral movable shaft is slidably connected to the sub-frame.

[0008] A further improvement of this utility model is that the main vehicle frame is provided with a drive motor, and the drive motor is fixedly connected to the outer wall of the sub-frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating column head achieves bidirectional transmission through the main universal joint shaft, the auxiliary universal joint shaft, and the main universal joint shaft. During the process of driving the main vehicle frame tires through the drive motor, the end shaft connecting rod provides support for the tires when the ground slope fluctuates. Without affecting the shock absorption effect, it can maintain support during high-frequency vibration or large impact. At the same time, in the state of front wheel steering, the end shaft connecting rod can be synchronously transmitted with the lateral movement of the lateral moving shaft through the cooperation of the lateral moving shaft. Thus, the shock absorption support effect on the sub-frame and the middle frame is maintained during the steering process, thereby further reducing overshoot or rebound during high-speed steering.

[0013] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Example Please see Figures 1-2A toy car includes a main frame 1. The bottom of the main frame 1 is equipped with a multi-axis co-movement assembly 2, a sub-frame 3, a middle frame 4, and a front wheel steering stabilization assembly 5. The multi-axis co-movement assembly 2 consists of four sets. The sub-frame 3 is rotatably connected to both ends of the main frame 1, and the middle frame 4 is fixedly connected to the bottom of the main frame 1. The front wheel steering stabilization assembly 5 is provided on both sides of the sub-frame 3. The multi-axis co-movement assembly 2 includes an end shaft connecting rod 21 and a rotating column head 22. The end shaft connecting rod 21 is fixedly connected to both ends of the rotating column head 22. One rotating column head 22 is rotatably connected to the middle frame 4, and the other rotating column head 22 is rotatably connected to the sub-frame 3.

[0015] To address the problems of existing toy cars using simple springs or rubber pads, which result in poor performance under high-frequency vibrations or large impacts, an inability to dynamically adjust to steering speeds or road bumps, and a tendency for overshoot or rebound during high-speed steering, this invention proposes a toy car that uses an end axle connecting rod 21 to support the tires as the ground slopes undulate. This maintains support under high-frequency vibrations or large impacts without affecting the shock absorption effect. Furthermore, when the front wheels are steering, the end axle connecting rod 21 can be synchronously driven with the lateral movement of the lateral moving axle 53 through the cooperation of the lateral movable axle 53, thus maintaining the shock absorption support effect on the subframe 3 and the middle frame 4 during steering.

[0016] In this embodiment, the intermediate frame 4 is rotatably connected to a main universal joint shaft 41. One end of the main universal joint shaft 41 is fixedly connected to one of the rotating column heads 22. The main universal joint shaft 41 is used for universal transmission between one of the rotating column heads 22 and the intermediate frame 4. The main universal joint shaft 41 serves as an axial connection between the rotating column head 22 and the intermediate frame 4. At the same time, the main universal joint shaft 41 is a universal joint, which prevents the end shaft connecting rod 21 from being affected by the left and right rotation of the wheel during rotation.

[0017] In this embodiment, the sub-frame 3 is rotatably connected to a sub-universal adapter shaft 31, which is fixedly connected to another rotating column head 22. The sub-universal adapter shaft 31 is used for universal transmission between the other rotating column head 22 and the sub-frame 3. The sub-universal adapter shaft 31 serves as an axial connection between the rotating column head 22 and the sub-frame 3, ensuring that the end shaft connecting rod 21 is not affected by the up-and-down movement of the wheel during rotation.

[0018] In this embodiment, the front wheel steering stabilization assembly 5 includes a transmission bracket 51, a front axle connecting rod 52, and a lateral movable shaft 53. The transmission bracket 51 is rotatably connected to the sub-frame 3, the front axle connecting rod 52 is rotatably connected to the transmission bracket 51, the lateral movable shaft 53 is rotatably connected to the front axle connecting rod 52, and the lateral movable shaft 53 is slidably connected to the sub-frame 3.

[0019] In this embodiment, the main vehicle frame 1 is provided with a drive motor 11, which is fixedly connected to the outer wall of the sub-frame 3.

[0020] In this embodiment, the wheel drive shaft is connected to the front axle connecting rod 52. During wheel steering, the front axle connecting rod 52 rotates along the inner side of the transmission bracket 51 as the wheel moves, while the lateral movable axle 53 moves laterally along the inner side of the sub-frame 3 as the front axle connecting rod 52 moves. At this time, the end axle connecting rod 21 is pulled by the lateral movable axle 53 and adapts to the direction of movement of the lateral movable axle 53 to ensure that the end axle connecting rod 21 remains stable during the buffer support process.

[0021] In this embodiment, it should be noted that the improvement of this utility model lies in providing support for the shock-absorbing part, solving the problem that existing toy cars cannot dynamically adjust according to steering speed or road bumps, and are prone to overshoot or rebound when steering at high speeds, without changing its drive structure or four-wheel structure.

[0022] The working principle of this invention is as follows: By setting the rotating column head 22, bidirectional transmission is achieved through the main universal joint shaft 41, the auxiliary universal joint shaft 31, and the main universal joint shaft 41. During the process of driving the tires of the main vehicle frame 1 through the drive motor 11, the end shaft connecting rod 21 provides support for the tires when the ground slope fluctuates. The end shaft connecting rod 21 can move synchronously with the front and rear ends of the tires when the ground slope fluctuates, thus maintaining support during high-frequency vibration or large impact without affecting the shock absorption effect. At the same time, when the front wheels are turning, the end shaft connecting rod 21 can be synchronously transmitted with the lateral movement of the lateral moving shaft 53 through the cooperation of the lateral moving shaft 53, the front axle connecting rod 52, and the transmission bracket 51. Thus, the shock absorption support effect for the sub-frame 3 and the middle frame 4 is maintained during the turning process, thereby further reducing overshoot or rebound during high-speed turning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
