Detailed Description

The present application is described in further detail below with reference to figures 1-5.

Referring to fig. 1 and 2, the embodiment of the application discloses a waterproof storage battery car button, including button 1, return spring 2, dabbing switch 3, base 4 and hinge bar 5, button 1 is articulated through hinge bar 5 with base 4, dabs switch 3 and pegs graft in base 4 and is close to button 1 one side, and return spring 2 is located and dabs between switch 3 and the button 1. After a rider presses the key 1, the return spring 2 is compressed, and the key 1 is contacted with the light touch switch 3 to switch on a circuit; after the key 1 is released, the return spring 2 resets and pushes the key 1 to leave the tact switch 3, and the circuit is disconnected.

Referring to fig. 2 and 3, the tact switch 3 includes a base 32, a switch cap 31 mounted on a side of the base 32 close to the key 1, and four pins 33 mounted on a side of the base 32 away from the key 1. The base 32 is generally provided with a metal elastic sheet for conducting electricity, and is wrapped with a layer of waterproof silicone membrane. In other embodiments, the tact switch 3 may have any type of switch structure, and the function of turning on the circuit by pressing the switch cap 31 and turning off the circuit by resetting the switch cap 31 may be realized. After the key 1 contacts the switch cap 31, the switch cap 31 is pressed down, so that the metal elastic sheet in the base 32 is stressed and contacts the bottom pin 33 to connect the circuit.

Referring to fig. 3 and 4, the key 1 includes a pressing portion 11 for pressing the switch cap 31, a limiting block 12 fixedly connected to one side of the pressing portion 11 close to the base 4, and a hinge portion 13, wherein the hinge portion 13 is hinged to the base 4 through a hinge rod 5. The pressing portion 11 includes a housing 112, a pressing plate 111 fixedly connected to one side of the housing 112 far away from the base 4, and a pressing column 113, wherein the housing 112 is provided with a cavity near the light touch switch 3, and the pressing column 113 is fixedly connected to the inner bottom wall of the cavity.

Referring to fig. 2 and 3, one end of the pressing plate 111 away from the hinge portion 13 protrudes relative to the housing 112, so that a labor-saving lever can be formed for convenient pressing. The pressing plate 111 is provided with a pressing groove 1111 at a side far from the housing 112 and far from the hinge portion 13, and the length of the pressing groove 1111 exceeds half of the length of the pressing plate 111, so that the contact area between a human hand and the key 1 can be increased, and the pressing is facilitated.

Referring to fig. 3 and 4, the squeeze column 113 includes a fixing column 1131 and a squeeze rod 1132, the fixing column 1131 and the squeeze rod 1132 are fixedly connected, and the diameter of the fixing column 1131 is greater than that of the squeeze rod 1132, so that the end edge of the squeeze rod 1132 can be prevented from being clamped to the gap of the return spring 2 in the using process of the button, and the button can be used more smoothly.

Referring to fig. 3 and 4, one end of the return spring 2 is sleeved on the outer side of the squeeze rod 1132 and abuts against the inner bottom wall of the cavity, and the other end of the return spring is sleeved on the outer side of the switch cap 31 and abuts against one side of the base 32 close to the switch cap 31, so that the return spring 2 is convenient to mount and limit.

Referring to fig. 4, in the embodiment of the present application, two limit blocks 12 are provided and are respectively fixedly connected to a side of the housing 112 away from the hinge portion 13 and a side of the housing adjacent to the hinge portion 13. After the button is installed, the limiting block 12 is abutted against the inner cavity wall of the handlebar, and the button 1 is not pressed at the moment; when the key 1 is released, the return spring 2 pushes the key 1 to return to the position where the limiting block 12 is blocked by the inner cavity wall of the handlebar, so that the key 1 cannot rotate outwards.

Referring to fig. 3 and 5, two hinge seats 42 are fixedly connected to one side of the base 4 and are spaced apart from each other, and the hinge seats 42 and the hinge parts 13 are hinged through the hinge rod 5. In the embodiment of the present application, the hinge rod 5 is a half hollow rivet, and after the hinge rod 5 passes through the hinge seat 42, the end of the hinge rod 5 is punched, so that the end of the hinge rod 5 is expanded to be fixed relative to the hinge seat 42, and the hinge rod 5 is rotatably connected to the hinge portion 13. In other embodiments, the hinge rod 5 may be fixedly connected to the hinge portion 13 and rotatably connected to the hinge base 42, or the hinge rod 5 may be rotatably connected to both the hinge portion 13 and the hinge base 42.

Referring to fig. 3 and 5, a limiting table 421 is fixedly connected between the ends of the two hinge bases 42 close to the base 4, the limiting table 421 is fixedly connected with the base 4, a limiting strip 131 is arranged at one end of the hinge portion 13 close to the base 4, and the limiting strip 131 abuts against the limiting table 421 when the key 1 is not pressed. The side of the limit table 421 away from the tact switch 3 is set to be an inclined surface, so that the abutting area of the limit strip 131 and the limit table 421 can be increased, and the key 1 is prevented from rotating outwards to be separated from the handlebar. When the button is pressed, the push button 1 may be rotated to bring the pressing column 113 into contact with the switch cap 31, thereby completing the circuit.

Referring to fig. 5, the two sides of the base 4 are fixedly connected with fixing seats 41, the fixing seats 41 are provided with through holes 412 for screws to pass through, and therefore workers can conveniently install the waterproof battery car button on the car handle.

Referring to fig. 3 and 5, the bottom wall of the slot 43 is provided with four through holes 431 for the pins 33 to pass through, the slot 43 can increase the contact area between the base 4 and the base 32, so that the base 4 and the tact switch 3 are tightly connected, the return spring 2 always applies a force to the base 32 towards the direction of the pins 33, so that the tact switch 3 and the slot 43 are more tightly connected, and rainwater leaking into the button is not easy to flow to the wiring position of the pins 33, thereby playing a role in water proofing.

The working principle of a waterproof storage battery car button of this application embodiment is as follows:

when the electric bicycle is in work, a rider holds the bicycle handle, the rider presses down the pressing groove with the thumb, the key moves towards the tact switch, the extrusion column is in contact with the switch cap and presses down, and the metal elastic sheet in the base is stressed to connect the circuit. After the rider releases the thumb, the return spring is reset, so that the extrusion column is separated from the switch cap, and the circuit is disconnected.

In rainy days, rainwater enters from gaps between the buttons and the handlebar, part of rainwater entering the buttons can be blocked by the limiting blocks, and the rest parts continue to flow to the tact switch. The light touch switch is in plug-in fit with the base and is under the pressure of the return spring, so that rainwater permeating into the button is not easy to flow to the wiring part of the pin, and a good waterproof effect is achieved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
