Description

Technical Field

[0001] This utility model relates to the field of brake handle technology, specifically an adjustable brake handle with a switch. Background Technology

[0002] The brake lever is a control component installed on the handlebars of electric vehicles, motorcycles, and other vehicles. It is a key brake lever structure for braking during riding. By squeezing the brake lever, the braking system transmits force, causing the brake lever structure to contact the wheel and generate friction, thereby reducing the speed or stopping the vehicle.

[0003] Current brake levers are often fixed to the handlebars of the vehicle, making it inconvenient for riders to adjust the angle of use according to their hand size and driving habits. Furthermore, they do not have a trigger switch, making it difficult to activate the vehicle's control system to optimize braking performance when the rider brakes. Based on this, we propose a new type of adjustable brake lever with a switch. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable brake handle with a switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable brake lever with a switch, comprising a lower lever body, an upper lever body mounted at the top of the lower lever body, an operating handle movably connected to one end of the upper lever body, a pressure sensing switch mounted at the bottom of the operating handle, a micro air pump and an outer adjusting cylinder sequentially mounted on one side of the lower lever body, an inner fixing cylinder rotatably connected inside the outer adjusting cylinder, side mounting plates evenly arranged at both ends of the inner fixing cylinder, fixing bolts threaded onto the side mounting plates, an annular reserved sliding cavity provided inside the side wall of the inner fixing cylinder, a reserved slider fixed on the outer adjusting cylinder and slidably connected to the annular reserved sliding cavity, a pressure-fixing airbag component provided on the inner side wall of the outer adjusting cylinder, and an air guide hose installed between the pressure-fixing airbag component and the micro air pump.

[0006] Preferably, the upper body of the handle, the operating handle, and the lower body of the handle are all made of carbon fiber, which improves the structural strength of the brake handle structure.

[0007] Preferably, the outer wall of the operating handle is provided with an anti-slip silicone layer, and locking screws are evenly arranged between the upper body and the lower body of the handle.

[0008] Preferably, the operating handle has a hollow structure, and the inside of the operating handle is provided with a wiring cavity that matches the pressure sensing switch.

[0009] Preferably, the top of the handle body is provided with a wire outlet hole that matches the pressure sensing switch, and the wire outlet hole is connected to the interior of the wiring cavity.

[0010] Preferably, a brake cable lead-out tube is provided on one side of the handle body.

[0011] Preferably, the output end of the micro air pump is provided with an air valve, and the air guide hose and the air valve are connected by a thread, so as to facilitate the disassembly and assembly of the air guide hose and the air valve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The adjustable brake lever with switch has an external adjustment cylinder installed, which optimizes the structure of the brake lever. First, the fixed connection structure consisting of the side mounting plate and the fixing bolt is used to fit the inner fixing cylinder into and fix it to the handle of the vehicle body. In specific operation, the rider can rotate the outer adjustment cylinder according to his hand size, strength and driving habits, through the sliding connection between the annular reserved sliding cavity on the inner fixing cylinder and the reserved slider on the outer adjustment cylinder, and change the use angle of the operating handle on the handle relative to the vehicle body, so that it is in a gripping state suitable for the rider. Then, turn on the micro air pump connected to the vehicle body power supply, and inflate the pressure-fixing airbag set in the inner wall of the outer adjustment cylinder through the air guide hose, so that it expands and presses into the gap of the annular reserved sliding cavity, thereby achieving the pressing and fixing of the inner fixing cylinder. Then, close the air valve to avoid air leakage, which improves the stability of the brake lever after the adjustment position is adjusted. In the future, when the position needs to be adjusted again, it is only necessary to use the threaded connection structure between the air guide hose and the air valve to remove the air guide hose to release the air.

[0014] (2) The adjustable brake lever with switch is equipped with a pressure sensor switch, so that when the brake lever is operated, the user's action of squeezing the operating handle will trigger the pressure sensor switch, which will transmit the brake signal to the vehicle's control system to realize functions such as cutting off the motor power and illuminating the brake lights, thus achieving efficient brake linkage function. On the other hand, the operating handle has a wiring cavity that matches the pressure sensor switch, and the top of the handle has a wire outlet hole that matches the pressure sensor switch, which facilitates the wiring of the pressure sensor switch. In addition, the anti-slip silicone layer on the outer wall of the operating handle improves the anti-slip effect when gripping. Attached Figure Description

The inner wall of the outer adjusting cylinder 12 is provided with a pressure-fixing airbag component 14. An air guide hose 9 is installed between the pressure-fixing airbag component 14 and the micro air pump 7.

[0028] The output end of the miniature air pump 7 is equipped with an air valve 8, and the air guide hose 9 and the air valve 8 are connected by a thread, which makes it easy to disassemble and assemble the air guide hose 9 and the air valve 8.

[0029] In use, firstly, using the fixed connection structure formed by the side mounting plate 10 and the fixing bolt 13, the inner fixing cylinder 11 is fitted into and fixed to the handlebar of the vehicle body. In specific operation, the rider, according to his own hand size, strength and driving habits, first rotates the outer adjusting cylinder 12 through the sliding connection between the annular reserved sliding cavity 15 on the inner fixing cylinder 11 and the reserved slider 16 on the outer adjusting cylinder 12, changing the usage angle of the operating handle 2 on the handlebar body 1 relative to the vehicle body, so that it is in a gripping state suitable for the rider.

This changes the angle of the operating handle 2 on the handlebar body 1 relative to the vehicle body, placing it in a gripping position suitable for the rider. Then, the miniature air pump 7 connected to the vehicle body's power supply is turned on, and air is inflated into the pressure-fixing airbag 14 located on the inner wall of the outer adjusting cylinder 12 through the air hose 9. This inflates the airbag and pushes it into the gap of the annular pre-reserved sliding cavity 15, achieving a tight fixation of the inner fixing cylinder 11. Finally, the air valve 8 is closed to prevent... The air leakage improves the stability of the brake lever after adjustment. When the position needs to be adjusted again, simply remove the air hose 9 to release the air by utilizing the threaded connection between the air hose 9 and the air valve 8. At the same time, the user's action of squeezing the operating handle 2 will trigger the pressure sensor switch 3, which transmits the brake signal to the vehicle's control system to achieve functions such as cutting off the motor power and illuminating the brake lights, thus realizing an efficient brake linkage function. In addition, by setting a wiring cavity inside the operating handle 2 that matches the pressure sensor switch 3, and setting a wiring hole 17 at the top of the handle body 1 that matches the pressure sensor switch 3, it is easy to wire the pressure sensor switch 3. Furthermore, the anti-slip silicone layer on the outer wall of the operating handle 2 improves the anti-slip effect when gripping.
