Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle handlebar switch structure, and in particular to a switch structure and handlebar switch. Background Technology

[0002] In the field of personal electric vehicles such as electric bicycles, electric motorcycles, and electric scooters, the braking system is a core component ensuring user safety. The braking signal is usually triggered by a brake switch installed on the handlebars. When the user squeezes the brake lever, the brake lever will activate a push rod or slider mechanism, which will ultimately press the trigger end of the brake switch, changing the switch state and sending a braking signal to the vehicle controller.

[0003] When a user squeezes the brake lever for an extended period of time due to negligence or an emergency, the traditional switch will remain in the triggered state. If the user attempts to start the vehicle without fully releasing the brake lever, the switch may instantly deactivate if the brake is accidentally released, causing the vehicle to start suddenly. This can easily lead to collisions, falls, or other safety accidents, especially at low speeds or when the vehicle is parked. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a switch structure and handlebar switch, which solves the safety hazard that the vehicle may start unexpectedly due to negligence after continuous braking.

[0005] This utility model also provides a switch structure and a handlebar switch as described above, including: a starter handle and a switch assembly. A handle connecting rod is fixedly connected inside the starter handle. A brake handle is provided on one side of the starter handle. A connecting plate is fixedly connected to one side of the brake handle. A push rod is fixedly connected to one side of the connecting plate. The switch assembly is fixedly connected to one side of the connecting block. The switch assembly includes a mounting box, a push plate, and a mounting plate. The push plate is located at the top of a spring. The push plate is fixedly connected to the push rod. A guide rod is movably connected inside the push plate. A spring is sleeved on the guide rod. One end of the spring abuts against the push plate, and the other end abuts against the bottom of the mounting plate. The mounting plate is fixedly connected inside the mounting box. A control switch is fixedly connected to its top, providing a buffering effect to avoid instantaneous impact on the control switch and extend the switch's lifespan.

[0006] According to the switch structure described in this utility model, a connecting block is fixedly connected to the handle connecting rod, and a brake handle is rotatably connected to one side of the connecting block, which simplifies the overall structure.

[0007] According to the switch structure described in this utility model, an elastic block is fixedly connected to the bottom of the push plate, and the trigger end of the control switch is located below the movement trajectory of the elastic block, which effectively reduces the mechanical impact and wear on control switches such as micro switches.

[0008] According to the switch structure described in this utility model, a connecting shaft is fixedly connected inside the connecting block, and the brake handle is rotatably connected to the connecting block through the connecting shaft, ensuring that the brake handle rotates smoothly, stably, and durablely.

[0009] According to the switch structure described in this utility model, a limiting rod is fixedly connected to the top of the mounting plate, and a limiting groove adapted to the limiting rod is provided on the push plate to ensure that the elastic block can be accurately aligned with the control switch.

[0010] According to the switch structure described in this utility model, when the push plate moves along the guide rod to the maximum stroke position, the limiting rod is inserted into the limiting groove to prevent the push plate from being excessively pressed, thereby protecting the spring from excessive compression.

[0011] This includes the switch structure described above.

[0012] According to the present invention, a handlebar switch is provided, wherein the control switch is used to control the circuit on / off of the start handlebar, and a control board is fixedly connected to one side of the connecting block. The control board is electrically connected to the control switch, thereby improving the intelligence and reliability of the system.

[0013] Beneficial effects:

[0014] The switch structure and handlebar switch of this technical solution use the brake handle linkage push rod to drive the push plate to press down and trigger the control switch. With the help of spring reset, guide rod and limit groove, the operation is stable and reliable. At the same time, the control board actively cuts off the circuit when the brake handle is squeezed for a long time and can only be triggered again after being released and squeezed again. This effectively solves the safety hazard of traditional switches that may cause the vehicle to start unexpectedly due to negligence after continuous braking, and significantly improves the safety and reliability of braking operation.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a switch structure and a handlebar switch, including: a start handle 1 and a switch assembly 2. A handlebar connecting rod 101 is fixedly connected inside the start handle 1. A brake handle 102 is provided on one side of the start handle 1. A connecting plate 1021 is fixedly connected to one side of the brake handle 102. A push rod 1022 is fixedly connected to the other side of the connecting plate 1021. A connecting block 103 is also fixedly connected to the handle connecting rod 101. The connecting block 103 is located near the brake handle 102. A connecting shaft 1023 is fixedly connected inside the connecting block 103. The brake handle 102 is rotatably connected to the connecting block 103 through the connecting shaft 1023, so that the brake handle 102 can swing around the connecting shaft 1023 relative to the start handle 1 and the connecting block 103.

[0026] The switch assembly 2 is a single unit and is fixedly connected to one side of the connecting block 103. The switch assembly 2 mainly includes a mounting box 201 as the outer shell, in which a mounting plate 205 is fixedly installed. The push plate 202 is the core moving part of the switch assembly 2. It is located above the mounting plate 205. The push plate 202 is movably connected to the inside of the push plate 202. A spring 204 is fitted on the guide rod 203. One end of the spring 204 abuts against the bottom of the push plate 202, and the other end abuts against the top of the fixedly installed mounting plate 205. The function of the spring 204 is to push the push plate 202 upward away from the mounting plate 205 under normal conditions and to provide a restoring force after the push plate 202 is pressed down.

[0027] Specifically, the push plate 202 is fixedly connected to the push rod 1022 extending from the brake handle 102. Therefore, when the operator squeezes the brake handle 102, the brake handle 102 rotates around the connecting shaft 1023, which drives the push rod 1022 to move through the connecting plate 1021, thereby driving the push plate 202 to overcome the elastic force of the spring 204 and move downward along the guide rod 203.

[0028] A control switch 206 is fixedly installed on the top of the mounting plate 205. An elastic block 2022 is fixedly connected to the bottom of the push plate 202. The trigger end of the control switch 206 is located directly below the downward movement trajectory of the elastic block 2022. When the push plate 202 is driven downward by the push rod 1022 to a certain stroke, the elastic block 2022 at its bottom will press against the trigger end of the control switch 206, thereby triggering the control switch 206 to act.

[0029] Specifically, in order to ensure the accuracy of the movement trajectory of the push plate 202 and limit its maximum stroke, a limit rod 207 is fixedly connected to the top of the mounting plate 205, and a limit groove 2021 that matches the shape and size of the limit rod 207 is provided on the push plate 202. When the push plate 202 moves downward along the guide rod 203 to the maximum stroke position, the limit rod 207 is just inserted into the limit groove 2021 on the push plate 202, which plays the role of rigid limit and guiding stability.

[0030] The control switch 206 is used to control the on / off of the circuit related to the start handle 1. A control board 104 is fixedly connected to one side of the connecting block 103. The control board 104 is electrically connected to the control switch 206 through wires.

[0031] Working principle: When the user squeezes the brake lever 102 to brake, the push plate 202 moves down, and the elastic block 2022 triggers the control switch 206, connecting the circuit. If the user maintains the brake for a long time, the push plate 202 will remain at its maximum travel position. At this time, although the control switch 206 is continuously pressed, the control board 104 will actively cut off the circuit. After that, even if the brake lever 102 is still squeezed, the circuit remains disconnected. Only when the user releases the brake lever 102, allowing the push plate 202 to return to its original position under the action of the spring 204, causing the elastic block 2022 to leave the trigger end of the control switch 206, and then squeezes the brake lever 102 again to make the push plate 202 move down and the elastic block 2022 triggers the control switch 206 again, will the control board 104 reconnect the circuit. This design effectively prevents the risk of the vehicle starting unexpectedly due to negligence after a long period of braking.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
