Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a waterproof handle switch assembly. Background Art

[0002] A switch assembly is provided at the handlebars of electric vehicles and motorcycles. By pressing the buttons on the upper parts, the corresponding switches are controlled to be turned on and off. The existing switch assembly structure is relatively simple. The circuit board is directly placed in the shell, and the buttons directly act on the switches of the circuit board to perform the switch operation.

[0003] However, since electric vehicles and motorcycles are exposed to the air, they will inevitably be exposed to rain or run in the rain, causing rainwater to enter the switch assembly through the buttons or connection gaps, directly causing a short circuit on the circuit board, posing a safety hazard. To this end, a waterproof handle switch assembly is proposed. Utility Model Content

[0004] The utility model aims to solve the problem of poor waterproofness of the handle switch assembly in the prior art and proposes a waterproof handle switch assembly.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A waterproof handle switch assembly includes a shell and a switch button. The top of the shell is provided with a button opening for the switch button to pass through. A pressing plate is fixedly provided at the bottom of the switch button. Elastic mechanisms are provided on the top inner wall of the shell and on both sides of the pressing plate. An annular sealing ring is fixedly provided at the edge of the upper surface of the pressing plate. The top inner wall of the shell is provided with an annular sealing groove matching the annular sealing ring. A soft waterproof cover is fixedly provided on the side wall of the switch button and on the top of the shell.

[0007] Preferably, the elastic mechanism includes a slider, a slide rod and a spring, the slider is fixedly arranged on the side wall of the pressing plate, the slide rod is fixedly arranged on the top inner wall of the shell, the slider is slidably connected to the rod wall of the slide rod, the spring is sleeved on the rod wall of the slide rod, and the two ends of the spring are respectively fixedly connected to the slider and the shell.

[0008] Preferably, the slide bar is a T-shaped bar, and the protrusion at the lower end of the slide bar can limit the position of the slider.

[0009] Preferably, one side of the soft waterproof cover has a large diameter, and the other side of the soft waterproof cover has a small diameter, and the soft waterproof cover is made of a polyurethane soft cover.

[0010] Preferably, the soft waterproof cover and the switch button as well as the soft waterproof cover and the housing are fixedly bonded by glue.

[0011] Preferably, a switch body is provided below the pressing plate.

[0012] Compared with the prior art, the utility model provides a waterproof handle switch assembly, which has the following beneficial effects:

[0013] 1. The waterproof handle switch assembly is provided with a pressing plate and an annular sealing ring. The pressing plate bounces upward due to the action of the elastic mechanism, so that the annular sealing ring cooperates with the annular sealing groove on the top inner wall of the shell. At this time, the pressing plate and the shell can be sealed. At the same time, a soft waterproof cover is provided on the side wall of the switch button, which can seal the switch button and the shell, thereby preventing rainwater from entering the interior of the shell through the gap of the switch button and preventing the circuit from short-circuiting.

[0014] 2. The waterproof handle switch assembly is provided with a slider, a slide bar and a spring. Both sides of the pressing plate can move on the slide bar through the slider. At the same time, the spring applies an upward elastic force to the slider, so that the switch button can automatically bounce upward.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts a double sealing structure between the switch button and the shell to prevent rainwater from entering the interior of the shell through the gap and causing a short circuit, thereby improving the safety of use.
