Description

Technical Field

[0001] The utility model belongs to the field of electric vehicles, and in particular relates to a waterproof electric vehicle handlebar. Background Art

[0002] The electric vehicle's handlebar, also known as the speed controller, is a key component for controlling the vehicle's speed. Its operating principle is primarily based on the Hall effect. Inside the handlebar, a linear Hall element is installed that senses the strength of magnetic lines of force. This Hall element is connected to three wires—typically red, black, and green—representing the positive, negative, and signal lines, respectively. Inside the handlebar, a magnet rotates as the handlebar is turned. The Hall element senses the changes in the magnetic force and transmits this signal to the controller. The controller then controls the motor's speed based on the strength of the signal.

[0003] The current electric vehicle handlebar structure is prone to water ingress on rainy days. If rainwater enters the connection between the Hall element and the wire, it will cause a short circuit at the connection point, which will cause the handlebar of the electric vehicle to malfunction and be unable to accurately accelerate, decelerate or switch, thus posing a certain safety hazard. Summary of the Invention

[0004] In view of the problems in the related art, the utility model proposes a waterproof electric vehicle handlebar to overcome the above technical problems existing in the existing related art.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a waterproof electric vehicle handlebar, comprising a handlebar head, wherein a card slot is provided inside the handlebar head, and a waterproof connector is mounted inside the card slot;

[0007] The waterproof connector includes a connector body and a cover plate that are engaged with each other. A wiring cavity is provided inside the connector body. One side of the connector body and the cover plate are both provided with corresponding wire grooves that are connected to the wiring cavity inside the connector body.

[0008] Furthermore, a partition plate located between adjacent wiring troughs is provided in the connector body, and a groove located between adjacent wiring troughs is provided on the inner side surface of the cover plate.

[0009] Furthermore, side card slots are provided on both sides of the connector body, and side card blocks capable of being engaged with the side card slots are provided on both sides of the cover plate.

[0010] Furthermore, a front card slot is provided on the front side of the connector body, and a front card block capable of being engaged with the front card slot is provided on the front side of the cover plate.

[0011] Furthermore, a glue injection hole communicating with the wiring cavity in the connector body is provided on the cover plate.

[0012] Furthermore, a guide hole communicating with the bottom of the slot is provided inside the turning handle.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, a waterproof joint is installed in the handlebar head of the electric vehicle, and the wiring part of the electric vehicle speed control circuit is sealed in the waterproof joint, so that the wiring part can be sealed and protected to prevent the wiring part from malfunctioning due to water infiltration on rainy days, which may cause electric vehicle malfunction and improve the stability and safety of electric vehicle riding; and a diversion hole connected to the bottom of the card slot is opened inside the handlebar head. When rainwater penetrates into the handlebar of the electric vehicle on rainy days, the rainwater inside the card slot where the waterproof joint is installed can be quickly diverted and discharged through the diversion hole, preventing rainwater from staying and gathering in the card slot, thereby preventing rainwater from seeping into the waterproof joint, and further improving the waterproof performance of the wiring part.

[0024] See also Figure 1-Figure 5 As shown, the utility model is a waterproof electric vehicle throttle, comprising a throttle head 1, a card slot 2 is provided inside the throttle head 1, and a waterproof connector 3 is clamped inside the card slot 2; the waterproof connector 3 includes a connector body 31 and a cover plate 32 that are engaged with each other, the connector body 31 is provided with a wiring cavity inside, and one side of the connector body 31 and the cover plate 32 are provided with corresponding wire grooves 33 that are connected to the wiring cavity inside the connector body 31;

[0025] During wiring, the Hall element in the electric vehicle's handlebar speed control circuit is clamped in the wiring cavity inside the connector body 31, and then the three wires to be connected to the Hall element are respectively extended into the wiring cavity inside the connector body 31 through the three wire grooves 33 on the side of the connector body 31 to connect to the Hall element. When the wiring is completed, the cover plate 32 is sealed and clamped with the connector body 31, thereby sealing the Hall element and the wiring point in the waterproof connector 3, so that the wiring point can be sealed and protected to prevent the wiring point from malfunctioning due to water ingress on rainy days, which may cause electric vehicle malfunction and improve the stability and safety of electric vehicle riding.

[0026] Specifically, a partition 37 located between adjacent wire grooves 33 is provided in the connector body 31, and a groove 38 located between adjacent wiring grooves 33 is provided on the inner side of the cover plate 32. The partition 37 can separate multiple wires in the wire group so that the wires do not interfere with each other to prevent short circuits at the wire joints. At the same time, when the cover plate 32 is sealed and engaged with the connector body 31, the partition 37 is engaged in the corresponding groove 38 to improve the firmness of the engagement between the cover plate 32 and the connector body 31.
