[0047] As can be seen from the above description, the setting of the elastic locking component 42 can reduce the risk of the first pin 41 accidentally dislodging from the first pin hole 311, thereby ensuring the locking effect of the first pin 41 on the telescopic arm 2 and the bracket 31.

[0048] Furthermore, a sleeve 25 is provided at the first through hole 21 for the first pin 41 to pass through.

[0049] As can be seen from the above description, the sleeve 25 can improve the phenomenon of the first pin 41 being scratched, and when the area of ​​the telescopic arm 2 with the first through hole 21 is made of hollow tube, the presence of the sleeve 25 can allow the first pin 41 to pass through the hollow tube more smoothly.

The end of the telescopic rod 23 away from the sleeve 22 is the distal end, and the connection position between the sleeve 22 and the main body 1 is the proximal end. The end of the telescopic rod 23 near the proximal end is slidably sleeved inside the sleeve 22. The second locking component 24 is used to lock the sleeve 22 and the telescopic rod 23.

[0051] As can be seen from the above description, the telescopic outrigger 2 has a simple structure and is easy to operate.

[0052] Furthermore, the second locking component 24 includes a spring and a locking head. The locking head is slidably disposed on the telescopic rod 23.

The locking holes 221 cooperate with the locking head.

[0053] As can be seen from the above description, the second locking component 24 has a simple structure and is easy for users to operate.

[0054] Furthermore, the second locking component 24 includes a second pin, the sleeve 22 is provided with a second through hole, the telescopic rod 23 is provided with a second pin hole, and one end of the second pin passes through the second through hole and is inserted into the second pin hole.

[0055] As can be seen from the above description, there are various specific structures for the second locking component 24, which can be selected and set according to actual needs.

[0056] Furthermore, the sleeve 22 is provided with telescopic rods 23 at both ends, and each telescopic rod 23 is connected to the wheel assembly 3.

[0057] As can be seen from the above description, a sleeve 22 connecting two telescopic rods 23 can simplify the structure of the electric toy car and facilitate the assembly and production of the electric toy car.

[0058] Furthermore, when the telescopic rods 23 at both ends of the sleeve 22 are in the retracted state, the distance between the rotating shafts 7 on the two telescopic rods 23 is A, and when the telescopic rods 23 at both ends of the sleeve 22 are in the extended state, the distance between the rotating shafts 7 on the two telescopic rods 23 is B, where 1.5A≤B≤2A.

[0059] As can be seen from the above description, selecting an appropriate telescopic rod extension ratio range can simultaneously ensure the stability and structural strength of the toy car.

[0060] Please refer to Figures 1 to 4One embodiment of this utility model is as follows: an electric toy car, including a main body 1, a telescopic support arm 2, a wheel assembly 3, and a first locking assembly 4. The front part of the main body 1 is provided with a front wheel 5 and a steering wheel 6; the telescopic support arm 2 has a proximal end and a distal end, the proximal end is connected to the rear part of the main body 1, and the distal end is provided with a rotating shaft 7. The distance between the proximal end and the distal end is adjustable; the wheel assembly 3 includes a bracket 31 and a rear wheel 32 rotatably connected to the bracket 31. The bracket 31 is rotatably connected to the distal end through the rotating shaft 7; the first locking assembly 4 is detachably connected to the telescopic support arm 2 and the bracket 31.

[0061] The first locking component 4 includes a first pin 41, with a first through hole 21 at the distal end and a first pin hole 311 on the bracket 31. One end of the first pin 41 passes through the first through hole 21 and is inserted into the first pin hole 311. When one end of the first pin 41 is inserted into the first pin hole 311, the telescopic arm 2 and the bracket 31 are locked together, and the bracket 31 can no longer rotate around the pivot 7. When the first pin 41 is removed, the bracket 31 can rotate around the pivot 7. At this time, the pivot 7 and the wheel assembly 3 form a universal wheel mechanism.

[0062] To facilitate user operation, a handle 43 is provided at the other end of the first pin 41. In this embodiment, the handle 43 is rotatably connected to the first pin 41. Specifically, the handle 43 is ring-shaped, sheet-shaped, or block-shaped.

[0063] In a preferred embodiment, the insertion end of the first pin 41 is provided with an elastic locking component 42. The elastic locking component 42 includes an elastic element and a ball. The elastic element contacts both the ball and the first pin 41. The ball is slidable radially along the first pin 41. The first pin hole 311 has a mating position that engages with the ball. When the ball engages with the mating position, a large pulling force needs to be applied to the first pin 41 to pull it out of the first pin hole 311. This reduces the risk of the first pin 41 accidentally dislodging from the first pin hole 311. The elastic element can be a spring pad, a compression spring, etc.

[0064] Optionally, a sleeve 25 is provided at the first through hole 21 for the first pin 41 to pass through. In one or more embodiments, the sleeve 22 is made of a hard material, such as Teflon.

[0065] The telescopic arm 2 includes a sleeve 22, a telescopic rod 23, and a second locking component 24. The end of the telescopic rod 23 away from the sleeve 22 is the distal end, and the connection position between the sleeve 22 and the main body 1 is the proximal end. The end of the telescopic rod 23 near the proximal end is slidably sleeved inside the sleeve 22. The second locking component 24 is used to lock the sleeve 22 and the telescopic rod 23.

[0066] In this embodiment, the second locking component 24 includes a spring and a locking head. The locking head is slidably mounted on the telescopic rod 23. The spring abuts against both the locking head and the telescopic rod 23. The sleeve 22 has multiple locking holes 221 spaced apart along its length, and the locking holes 221 engage with the locking head. When the locking head engages with locking holes 221 at different positions, the relative positional relationship between the telescopic rod 23 and the sleeve 22 is different. Optionally, the number of locking holes 221 engaging with the same locking head is two. When the locking head engages with one of the locking holes 221, the telescopic arm 2 is in a retracted state; when the locking head engages with the other locking hole 221, the telescopic arm 2 is in an extended state. Furthermore, it should be noted that the spring and locking head essentially constitute the core structure of a spring plunger. That is, in practical applications, it is also feasible to directly use a spring plunger for the second locking component 24.

[0067] Furthermore, the second locking component 24 includes a second pin, the sleeve 22 is provided with a second through hole, and the telescopic rod 23 is provided with a second pin hole. One end of the second pin passes through the second through hole and is inserted into the second pin hole. That is, the telescopic rod 23 and the sleeve 22 can also be locked by a pin structure.

[0068] In a preferred embodiment, the sleeve 22 is provided with telescopic rods 23 at both ends, and each telescopic rod 23 is connected to the wheel assembly 3.

[0069] When the telescopic rods 23 at both ends of the sleeve 22 are in the retracted state, the distance between the pivots 7 on the two telescopic rods 23 is A. When the telescopic rods 23 at both ends of the sleeve 22 are in the extended state, the distance between the pivots 7 on the two telescopic rods 23 is B, where 1.5A ≤ B ≤ 2A. When B < 1.5A, the extension and retraction of the telescopic arm 2 does not significantly improve the stability of the toy car. When B > 2A, the telescopic arm 2 needs to be made of higher strength materials, increasing the manufacturing cost of the toy car and severely affecting its passability. Therefore, choosing 1.5A ≤ B ≤ 2A better meets the user's needs.

[0070] In one or more embodiments, the main body 1 is provided with a power supply assembly (not shown) for driving the front wheel 5. The power supply assembly includes an electrically connected drive motor and a battery. The drive motor drives the front wheel 5 to rotate, thereby providing forward power for the electric toy car.

[0071] In summary, the electric toy car provided by this utility model has a novel structure and can be adjusted between normal driving mode and drift driving mode, which is convenient for users and enhances the user experience.

[0072] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
