Brand power and technological strength have become the core of competition. The children's electric toy cars, electric engineering vehicles, electric excavators, electric loaders, and electric forklifts sold on the market, especially the toy cars that children can drive, require continuous technological innovation as the market continues to expand.

[0003] However, most existing children's toy cars use linkage suspension, which not only tilts and sways from side to side when driving, but is also bumpy and difficult to control, making it difficult to meet people's demand for high-end toys. In order to avoid the above-mentioned technical problems, it is indeed necessary to provide an independent suspension for children's toy cars to overcome the defects mentioned in the prior art. Utility Model Content

[0004] This utility model provides an independent suspension for children's toy cars, which can effectively solve the problem mentioned in the background art that most existing children's toy cars are linked suspensions, which not only tilt and sway from side to side when driving, but are also bumpy and difficult to control, making it difficult to meet people's demand for high-end toys.

[0016] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0017] 1. Equipped with a suspension system, when the toy car travels to uneven ground, the up-and-down movement of the wheels causes the main suspension to move up and down. At this time, the main suspension compresses the rotating block, telescopic damper, and shock absorber spring, thereby absorbing the shock of the car and preventing excessive bumps during driving. On remote-controlled toy cars, the car's driving posture can be controlled more stably. Furthermore, when the suspension system is used on medium-sized drivable toy cars, the driving experience can be improved through suspension shock absorption.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-4 As shown, this utility model provides a technical solution: an independent suspension for a children's toy car, including a main suspension 1, with a suspension assembly 2 installed at the top of the main suspension 1;

[0030] The suspension assembly 2 includes a chassis connecting ring 201, a wheel connecting ring 202, a mounting groove 203, a rotating rod 204, a rotating block 205, a telescopic damper 206, a shock absorber spring 207, a connecting block 208, a fixing rod 209, a sub-suspension 210, a through groove 211, and a positioning block 212.

[0031] A chassis connecting ring 201 is welded to one end of the main suspension 1, and a wheel connecting ring 202 is welded to the other end face of the main suspension 1. There are two chassis connecting rings 201 and two wheel connecting rings 202. The two chassis connecting rings 201 and two wheel connecting rings 202 are symmetrically installed on both sides of the main suspension 1 and the sub-suspension 210 to facilitate driving stability. An installation groove 203 is opened at the middle of the top of the main suspension 1. A rotating rod 204 is embedded in the inner side of the installation groove 203. A rotating block 205 is rotatably sleeved on the outer side of the rotating rod 204. A movable groove is opened on the inner side of the rotating block 205. The rotating block 205 is rotatably connected to the rotating rod 204 through the movable groove, which is conducive to rotation.

[0032] A telescopic damper 206 is installed at the top of the rotating block 205. A shock-absorbing spring 207 is sleeved on the outside of the telescopic damper 206. The two ends of the telescopic damper 206 are connected to the rotating block 205 and the connecting block 208 respectively. The two ends of the shock-absorbing spring 207 are spot-welded to the rotating block 205 and the connecting block 208 respectively for easy shock absorption. A connecting block 208 is welded to the top of the telescopic damper 206. A fixing rod 209 is welded to the inner side of the connecting block 208. A sub-suspension 210 is provided on the outside of the shock-absorbing spring 207. A through groove 211 is opened on the inner side of the sub-suspension 210 at the position corresponding to the shock-absorbing spring 207. A positioning block 212 is rotatably sleeved on the outside of the fixing rod 209.

[0033] A connecting component 3 is installed on the inner side of the wheel connecting ring 202;

[0034] The connecting assembly 3 includes a limiting rod 301, a threaded rod 302, an extended limiting rod 303, an extended threaded hole 304, a limiting nut 305, and a limiting bracket 306;

[0035] A limiting rod 301 is slidably installed on the inner side of a wheel connecting ring 202. A threaded rod 302 is threadedly connected to the inner side of the limiting rod 301. An extended limiting rod 303 is welded to one end of the threaded rod 302. The outer diameter of the limiting rod 301 is equal to the outer diameter of the extended limiting rod 303. The outer diameter of the limiting rod 301 is equal to the inner diameter of the wheel connecting ring 202, which is beneficial for accommodating tires of different sizes. An extended threaded hole 304 is opened on the inner side of the limiting rod 301 at the corresponding position of the threaded rod 302. A limiting nut 305 is threadedly connected to the outer side of the extended limiting rod 303. A limiting bracket 306 is threadedly connected to the outer side of the limiting rod 301.

[0036] The working principle and usage process of this utility model are as follows: First, connect the positioning block 212 to the chassis, connect the chassis connecting ring 201 to the car chassis, connect the wheel connecting ring 202 to the wheel, and connect the fixing rod 209 and the positioning block 212 to the car chassis.

[0037] By setting two parallel suspensions, the main suspension 1 and the secondary suspension 210, the chassis and wheels of the toy car can be connected at multiple points. When driving, the range of wheel sway will be limited to a certain range to prevent excessive swaying and body bumps. When driving on uneven ground, the up-and-down movement of the wheels will cause the main suspension 1 to move up and down. At this time, the main suspension 1 will compress the rotating block 205, the telescopic damper 206 and the shock absorber 207. When the main suspension 1 sways, the rotating block 205 will rotate on the inner side of the mounting groove 203 on the outer side of the rotating rod 204, thereby absorbing the shock of the car and preventing excessive bumps when driving. In remote-controlled toy cars, the car's driving posture can be controlled more stably. When the suspension system is used in a medium-sized toy car that can be driven, the driving experience can be improved through suspension shock absorption.

[0038] Next, the toy car tires come in different sizes. When installed on the side of the smaller tire, the extension limiting rod 303 can be rotated to move the threaded rod 302 inward toward the extension threaded hole 304. At this time, the distance between the limiting rod 301 and the extension limiting rod 303 can be reduced, thereby connecting the main suspension 1 and the sub-suspension 210 to the wheel. When the wheel is larger, the extension limiting rod 303 can be rotated in the opposite direction to increase the distance between the limiting rod 301 and the wheel to accommodate larger tires. Depending on the connection of the car, the limiting nut 305 or the limiting bracket 306 can be selected to connect the main suspension 1 to the car, further improving the applicability of the suspension.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
