[0002] Children's electric vehicles mainly refer to a type of toy car driven by an electric motor that children can drive and sit in, such as electric cars, electric motorcycles, and electric engineering vehicles. These simulated children's toys are very popular with children of the appropriate age and their parents, allowing them to imitate adults driving various vehicles, comprehensively exercising children's control and thinking abilities, and broadening their horizons.

[0003] Most children's cars on the market do not have speed control. Some children's cars with speed control usually use a gear switch to control the speed, which results in a noticeable jerk when the car accelerates or decelerates. They cannot imitate the speed adjustment of adult cars or motorcycles.

[0004] Therefore, it is necessary to improve upon the above-mentioned issues. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable speed handle and children's vehicle with a simpler structure, more reasonable design, increased simulation effect and playability of children's vehicles, and more fun for children.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example:

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, an adjustable speed handle, mounted on a stroller, includes a positioning seat 2 fixed to a handle frame 1. A positioning rod 3 is mounted on one side of the positioning seat 2, and a rotating handle 4 is sleeved on the positioning rod 3. An elastic element 5, looped around the positioning rod 3, connects the positioning seat 2 and the rotating handle 4. The elastic element 5 undergoes elastic deformation as the rotating handle 4 rotates. A potentiometer 6 is mounted inside the positioning seat 2. The potentiometer 6 is connected to the electric system via a wire 7 and is used to adjust the input power of the electric system. This utility model has a simple structure. By connecting the positioning seat and the rotating handle with an elastic element looped around the positioning rod, the elastic element moves freely without jamming or delay. Its structure is sturdy and durable, reasonable, and highly safe, making it easier to handle and operate than traditional strollers, providing a safer feel, and reducing costs.

[0030] The positioning seat 2 has a positioning cavity 20 and a receiving cavity 21, which are connected. The elastic element 5 is partially housed in the positioning cavity 20, and the potentiometer 6 is located in the receiving cavity 21. The potentiometer 6 is connected to the rotating handle 4 and rotates synchronously.

[0031] The elastic element 5 is a torsion spring; the torsion spring surrounds the outer wall of the handlebar frame 1, and the torsion spring undergoes elastic deformation as the handlebar 4 rotates. When the handlebar 4 rotates, the connection and fixing relationship between the various parts causes the torsion spring to undergo elastic deformation, applying a force to the rotation of the handlebar 4 in the opposite direction to the rotation direction. The larger the angle of rotation of the handlebar 4, the greater the force, mimicking the damping effect produced by the acceleration of an adult motorcycle. It can also allow the handlebar 4 to return to its original position after it is no longer rotated, specifically by resetting the potentiometer.

[0032] like Figure 2 and Figure 3 As shown, a limiting groove 40 is installed on the inner side of the rotating handle 4, and a positioning pin 41 for fastening one end of the elastic element 5 is inserted into the limiting groove 40; a through hole 23 for the handle frame 1 to pass through is provided in the positioning seat 2, and a limiting cylinder 24 is provided in the positioning seat 2 and coaxially arranged with the through hole 23, and the elastic element 5 abuts against the limiting cylinder 24; by setting the limiting cylinder 24, the elastic element 5 can be prevented from shifting and shaking, so that the rotating handle 4 is more stable and safe when it undergoes elastic deformation during rotation.

[0033] The positioning seat 2 is also provided with a positioning block 22 for fastening one end of the elastic member 5. The positioning block 22 is located in the limiting cylinder 24 near the through hole 23. In this embodiment, the two ends of the elastic member 5 are fastened by the positioning pin 41 and the positioning block 22, so that the positioning seat 2 and the rotating handle 4 are in the initial state and the stroller will not move.

[0034] The height of the limiting cylinder 24 is 1 / 4 to 1 / 2 of the height of the positioning seat 2. In this embodiment, the height of the limiting cylinder 24 is 1 / 4 of the height of the positioning seat 2, and it is only necessary to limit the elastic element 5 within the limiting cylinder 24.

[0035] A non-slip sleeve 42 is fitted onto the outer wall of the rotating handle 4; this makes it easy to grip the handle and accurately control the speed changes of the child vehicle.

[0036] like Figure 2As shown, an end cap 8 is fixed at the end of the positioning rod 3 away from the positioning seat 2. There is a gap between the end cap 8 and the rotating handle 4. By adopting the above technical solution, the rotation of the rotating handle 4 is more flexible. At the same time, the operating environment of the rotating handle 4 is safer. The outer end face of the end cap 8 is on the same horizontal plane as the rotating handle 4. While ensuring the safety of the entire adjustable speed handle, the overall aesthetics are further improved.

[0037] The outer side of the end cap 8 has a guide inclined surface 9, which increases the contact area with the user during use, thereby ensuring the safety of use.

[0038] Reference Figure 5 The invention discloses a children's stroller, including a stroller body 100, a handle frame 1 mounted on the stroller body 100, and a fixed handle 101 and an adjustable speed handle 102 mounted at both ends of the handle frame 1.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0040] Although this document uses numerous reference numerals from the accompanying drawings—handle bracket 1, positioning seat 2, positioning rod 3, rotating handle 4, elastic element 5, potentiometer 6, wire 7, end cap 8, guide inclined surface 9, positioning cavity 20, receiving cavity 21, positioning block 22, through hole 23, limiting cylinder 24, limiting groove 40, positioning pin 41, anti-slip sleeve 42, stroller body 100, fixed handle 101, adjustable speed handle 102, etc.—the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
