Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle accessories, and particularly relates to a handle. Background Art

[0002] An electric vehicle, that is, an electric drive vehicle, also known as an electric car. Generally speaking, an electric vehicle uses a battery as an energy source, and through components such as a controller and a motor, it converts electrical energy into mechanical energy to move, and controls the vehicle speed by changing the magnitude of the current.

[0003] An electric vehicle is usually controlled by a handle. The handle of an existing children's entertainment electric vehicle has more connecting parts, resulting in a larger volume, which is not convenient for children to hold and control, and affects its use comfort. Content of the Utility Model

[0004] Based on the above problems, the purpose of the utility model is to provide a handle with a small volume and comfortable for children to hold.

[0005] For the above problems, the following technical solution is provided: A handle includes a mounting seat connected to a handlebar tube, a fastening ring for locking the handlebar tube, a locking bolt cooperating with the fastening ring, and a grip connected to the mounting seat. A fixed tube seat is connected to the mounting seat. An installation hole is axially formed in the fixed tube seat. The grip is rotatably connected to the fixed tube seat through the installation hole. An installation box is provided on the fixed tube seat. A circuit board is provided in the installation box. A Hall sensor is provided on the circuit board. A magnet cooperating with the Hall sensor is installed on the grip.

[0006] In the above structure, by connecting the grip to the fixed tube seat, the number of components can be reduced, thereby reducing the diameter of the grip and shortening the length of the grip, and further reducing the overall volume of the utility model, which is convenient for children to hold and improves the comfort of children's holding. By driving the magnet to rotate relative to the Hall sensor through the grip, the speed of the children's vehicle is adjusted.

[0007] The utility model is further provided that the grip includes a grip tube connected to the fixed tube seat and a retaining ring integrally formed therewith. The grip tube protrudes towards the mounting seat and is provided with a clamping block. The clamping block passes through the installation hole and is clamped at one end facing the mounting seat. The magnet is installed on the retaining ring.

[0008] In the above structure, through the clamping cooperation between the clamping block and the installation hole of the fixed tube seat, the installation of the grip can be facilitated, thereby improving the assembly convenience of the utility model. By providing a retaining ring, the limit after the clamping block is clamped on the fixed tube seat can be facilitated, and further the stability after the grip is installed is improved.

[0009] The utility model is further provided that three clamping blocks are circumferentially spaced relative to the grip tube.

[0010] With the above structure, the connection strength between the grip and the fixed socket can be improved, thereby enhancing the stability of the grip and the reliability of the present utility model.

[0011] The present utility model is further configured such that a relief opening is provided on the outer side of the snap ring opposite to the snap block.

[0012] In the above structure, by providing the relief opening, it is convenient for the snap block to undergo a certain amount of elastic deformation, and thus it is convenient for the snap block to penetrate through the mounting hole and be engaged with the fixed socket, improving the assembly convenience of the present utility model.

[0013] The present utility model is further configured such that an arc-shaped block is provided at one end of the snap ring facing the fixed socket. The arc-shaped block is arranged in the rotation direction of the grip, and a mounting groove for mounting a magnet is provided on the side of the arc-shaped block facing the Hall sensor.

[0014] In the above structure, by providing the arc-shaped block, it is convenient for the installation of the magnet and for cooperation with the Hall sensor to adjust the vehicle speed, with more stable signal transmission, thereby enhancing the reliability of the present utility model.

[0015] The present utility model is further configured such that a groove is provided on the fixed socket facing the snap ring. A first limiting block that abuts against one end of the arc-shaped block is provided in the groove, and a second limiting block is provided in the groove in the rotation direction of the arc-shaped block.

[0016] In the above structure, by providing the first limiting block and the second limiting block, the rotation stroke of the grip can be limited, thereby enhancing the reliability of the present utility model. By providing the groove, it can cooperate more closely with the grip, thereby improving the compactness of the structure of the present utility model and enhancing the structural strength of the present utility model.

[0017] The present utility model is further configured such that the mounting box includes a box body integrally provided with the fixed socket and a box cover snap-fitted with the box body. An opening groove for the box cover to pass through is provided on the outer circumference of the mounting seat.

[0018] In the above structure, by providing the box body and the box cover, it is convenient for the installation of the circuit board, and thus it is convenient for the production and assembly of the present utility model. By providing the opening groove, it is convenient for the mounting seat to provide an installation space for the mounting box, and thus the overall volume of the present utility model can be correspondingly reduced, improving the comfort of a child's grip.

[0019] The present utility model is further configured such that a fixing post is provided at one end of the fixed socket facing the mounting seat. A fixing hole is provided on the fixing post, and a connection hole corresponding to the fixing hole is provided on the mounting seat.
