The utility model can greatly improve the shock absorption performance of the toy car and the stability of the steering structure itself, so that the toy car can smoothly complete the driving work.

[0004] However, this device cannot be applied to toy cars with different steering wheel positions during actual use, and the applicability of the device is relatively low. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a steering mechanism for toy cars, which can effectively solve the problem of relatively low applicability of the device.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A steering mechanism for toy cars includes a U-shaped frame. Swing arm assemblies are provided at both the left and right ends of the U-shaped frame. The swing arm assembly is jointly composed of an upper swing arm and a lower swing arm. A support frame is rotatably installed between the upper swing arm and the lower swing arm on the same side. A shock absorber is also rotatably installed between the upper swing arm and the U-shaped frame. A steering assembly is provided at the rear end of the U-shaped frame.

[0008] Preferably, the support frame includes a rotating shaft rotatably connected to the upper swing arm and the lower swing arm. A connecting shaft is further fixed on the outer surface of the rotating shaft on the side far from the U-shaped frame, and a connecting plate is further fixed on the rear side of the outer surface of the rotating shaft.

[0009] Preferably, the steering assembly includes a mounting plate fixed to the middle of the rear end of the U-shaped frame. A U-shaped groove is formed at the upper end of the mounting plate. A sliding shaft is slidably mounted in the inner cavity of the U-shaped groove. A connecting rod is fixed to the upper end of the sliding shaft. Two arc-shaped springs are provided in the inner cavity of the U-shaped groove. The upper end of the connecting rod is fixed with an inverted U-shaped bracket. A lever is movably mounted in the inner cavity of the inverted U-shaped bracket. A steering shaft is also fixed to the front side of the upper end of the lever.

[0010] Preferably, the connecting rod is rotatably connected to the two connecting plates, and the two arc-shaped springs are respectively located on the left and right sides of the sliding shaft.

[0011] Preferably, a plurality of rotating wheels are rotatably mounted at both the left and right ends of the lever.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0022] As Figure 1 shown, a steering mechanism for a toy car includes a U-shaped frame 1. The U-shaped frame 1 is used to connect with the vehicle body. Swing arm assemblies 11 are provided at both the left and right ends of the U-shaped frame 1. The swing arm assembly 11 is jointly composed of an upper swing arm 12 and a lower swing arm 13. A support frame 14 for connecting the tires is rotatably installed between the upper swing arm 12 and the lower swing arm 13 on the same side. A shock absorber 15 is also rotatably installed between the upper swing arm 12 and the U-shaped frame 1. Among them, the swing arm assembly 11 and the shock absorber 15 jointly form a double-wishbone suspension, which can enable the toy car to be shock-absorbed when driving. A steering assembly 2 is provided at the rear end of the U-shaped frame 1.

[0023] As Figure 2 shown, the support frame 14 includes a rotating shaft 141 rotatably connected to the upper swing arm 12 and the lower swing arm 13. The rotating shaft 141 is rotatably connected between the upper swing arm 12 and the lower swing arm 13, which can enable the rotating shaft 141 to rotate between the upper swing arm 12 and the lower swing arm 13. At the same time, when the upper swing arm 12 and the lower swing arm 13 rotate on the outer surface of the U-shaped frame 1, the rotating shaft 141 can move along with the upper swing arm 12 and the lower swing arm 13. And due to the design of the shock absorber 15, the vibration received by the tire is offset by the shock absorber 15. A connecting shaft 142 for connecting the tire is also fixed on the side of the outer surface of the rotating shaft 141 away from the U-shaped frame 1. The fixed connection between the connecting shaft 142 and the rotating shaft 141 enables the tire to rotate around the rotating shaft 141. At the same time, by rotating the two tires, the purpose of steering is achieved. A connecting plate 143 is also fixed on the rear side of the outer surface of the rotating shaft 141.

[0024] As Figure 3 - Figure 5As shown in the figure, the steering assembly 2 includes a mounting plate 21 fixed to the middle of the rear end of the U-shaped frame 1. An upper end of the mounting plate 21 is provided with a U-shaped groove 22. A sliding shaft 23 is slidably mounted in the inner cavity of the U-shaped groove 22. An upper end of the sliding shaft 23 is fixed with a connecting rod 24. The connecting rod 24 is rotatably connected to two connecting plates 143. Due to the design that the rotating shaft 141 is rotatably connected to the upper swing arm 12 and the lower swing arm 13, when the connecting rod 24 moves left or right, the rotating shaft 141 can rotate clockwise or counterclockwise, so as to achieve the purpose of tire steering. Two arc-shaped springs 25 are arranged in the inner cavity of the U-shaped groove 22, and the two arc-shaped springs 25 are respectively located on the left and right sides of the sliding shaft 23. The two arc-shaped springs 25 can facilitate the reset of the sliding shaft 23. Due to the elastic design of the arc-shaped spring 25, the sliding shaft 23 can always be located in the middle of the U-shaped groove 22.

[0025] In addition, an inverted U-shaped bracket 26 is fixed to the upper end of the connecting rod 24. When the inverted U-shaped bracket 26 is connected to the connecting rod 24, a bolt connection design is adopted, so that the position of the inverted U-shaped bracket 26 above the connecting rod 24 can be changed during the design of the device. Further, the device can be applied to toy cars with different steering wheel positions (for example: the steering wheel of the toy car is located in the middle, on the right, etc.), increasing the applicability of the device during use. A lever 27 is movably mounted in the inner cavity of the inverted U-shaped bracket 26. A plurality of rotating wheels 28 are rotatably mounted at both the left and right ends of the lever 27.

[0026] Among them, the plurality of rotating wheels 28 can facilitate the movable connection between the lever 27 and the inverted U-shaped bracket 26. Further, when the lever 27 rotates around the steering shaft 29 (that is, when the driver rotates the steering wheel), it can drive the inverted U-shaped bracket 26 to slide. At the same time, through the movable connection between the sliding shaft 23 and the U-shaped groove 22, the connecting rod 24 can be moved. Then, through the rotational connection between the connecting rod 24 and the two connecting plates 143, the purpose of turning the toy car is achieved. A steering shaft 29 is also fixed to the front side of the upper end of the lever 27. Among them, the steering shaft 29 is used to be connected to the steering wheel, and during the design of the toy car, the steering shaft 29 is rotatably connected to the vehicle body, and the rotational connection part can serve as a support frame for the steering shaft 29.

[0027] The specific implementation manner of this embodiment is as follows: When the device is used, the U-shaped frame 1 is connected to the vehicle body of the toy car by bolts, and then the steering shaft 29 is rotatably connected to the vehicle body. And because the toy car is designed with a single seat or a double seat during design, the device can adjust the position of the inverted U-shaped bracket 26 at the upper end of the connecting rod 24 according to different toy cars. And due to the design of the U-shaped groove 22, no matter where the inverted U-shaped bracket 26 is located above the connecting rod 24, the rotation of the steering shaft 29 will not affect the steering of the toy car.

[0028] It should be noted that the specific installation methods and control methods of the swing arm, shock absorber 15, arc spring 25, etc. in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
