To address this, vehicles are equipped with an anti-lock braking system (ABS). The ABS releases hydraulic pressure when the wheel is about to lock up. Typically, the ABS is located within the brake system's hydraulic lines, making it inconvenient to install, remove, and maintain. Utility Model Content

[0003] To address the problems of inconvenient disassembly and installation and difficult maintenance of anti-lock braking systems (ABS), this application provides a vehicle handle with an external ABS.

[0004] The vehicle handlebar with an external anti-lock braking system provided by this utility model adopts the following technical solution:

The ABS device includes a drive member and a cam connected to the drive member. The first brake lever is hinged to the mounting base, and the second brake lever is hinged to the first brake lever. The drive member of the ABS device is fixed to the first brake lever. One side of the second brake lever is hinged to a push rod for controlling the brake, and the other side of the second brake lever abuts against the far rest point of the cam.

[0006] Preferably, the fixing seat includes a main body, a fixing part, a hinge part, and an oil receiving part; the main body has a cavity, and a first interface and a second interface are respectively provided at opposite ends of the cavity. The first interface is connected to the external environment and allows the push rod to pass through, and the second interface is connected to the brake oil circuit. A piston is provided in the main body, and the piston divides the cavity into an air chamber and an oil chamber. The piston is hinged to the push rod.

[0007] Preferably, the hinge portion is disposed at one end of the main body portion, and the hinge portion and the first interface are located at the same end. The hinge portion includes a first hinge plate, a second hinge plate, and a base plate connecting the two. A clearance space is formed between the first hinge plate, the second hinge plate, and the base plate. The first brake lever is hinged in the clearance space through a hinge shaft.

[0008] Preferably, the fixing part has a docking hole for docking with the handlebars of the vehicle. The fixing part also has a seam that extends from the outside to the inside into the docking hole. The fixing part is divided into a first seam end and a second seam end at the seam. The first seam end is connected to the hinge part, and a screw is threaded between the first seam end and the second seam end.

[0009] Preferably, the oil receiving part is disposed at one end of the main body, the oil receiving part and the second interface are located at the same end, the oil receiving part is provided with an oil hole, one end of the oil hole is connected to the second interface, and the other end of the oil hole is connected to the brake oil circuit.

[0015] The beneficial effects of this utility model are as follows:

[0016] The first brake lever, when rotated, uses a cam and the second brake lever to push the push rod forward. The force of the push rod is then transmitted to the brake pads of the wheel through the brake fluid, achieving braking. When the wheel is about to lock up, the drive component of the anti-lock braking system (ABS) drives the cam to rotate. Under the action of the cam and hydraulic pressure, the second brake lever repeatedly abuts against the far and near rest points of the cam, thereby achieving high-frequency intermittent braking and preventing lock-up. Compared with the existing technology where the ABS is usually located in the hydraulic circuit of the braking system, this utility model places the ABS externally on the vehicle handlebars, achieving the anti-lock effect while also making the ABS easy to install, remove, and maintain.

[0023] The following will combine Figures 1-5 The present invention will be further described in conjunction with the embodiments.

[0024] This embodiment discloses a vehicle handle with an external anti-lock braking system.

[0025] Reference Figures 1 to 3 Taking the handlebar on the left side of the vehicle as an example, the vehicle handlebar includes a mounting base 4, a first brake lever 1, a second brake lever 2, and an anti-lock braking system. The vehicle handlebar is fixed to the handlebar of the vehicle via the mounting base 4.

[0026] Reference Figure 3 and Figure 4The mounting base 4 includes an integrally formed main body 41, a fixing part 42, a hinge part 43, and an oil receiving part 44. The main body 41 has a cavity 410. A first interface 411 and a second interface 412 are respectively located at opposite ends of the cavity 410. The cavity 410 is connected to an open air environment through the first interface 411 and to a closed brake fluid circuit through the second interface 412, thus containing both air and brake fluid. A piston 413 is disposed within the main body 41. The shape of the piston 413 corresponds to the cross-sectional shape of the cavity 410, thereby isolating the air and brake fluid within the cavity 410 to form an air chamber and an oil chamber, respectively. In this embodiment, both the cavity 410 and the piston 413 have circular cross-sections.

[0027] Reference Figure 3 and Figure 4 The hinge portion 43 is connected to one end of the main body portion 41, and the oil receiving portion 44 is connected to the other end of the main body portion 41. The hinge portion 43 is provided with a first interface 411 adjacent to the cavity 410, and the oil receiving portion 44 is provided with a second interface 412 adjacent to the cavity 410.

[0028] Reference Figure 3 and Figure 4 An oil hole 441 is provided in the oil receiving part 44. The oil hole 441 passes through the opposite ends of the oil receiving part 44. The oil receiving part 44 is connected to the second interface 412 of the main body part 41 through one end of the oil hole 441, and connected to the brake oil circuit through the other end of the oil hole 441.

[0029] Reference Figures 2 to 4 The hinge portion 43 is used to install the first brake lever 1. The hinge portion 43 includes a first hinge plate 431 and a second hinge plate 432 symmetrically arranged, and a base plate 433 connected between the bottoms of the first hinge plate 431 and the second hinge plate 432. A U-shaped clearance space is formed between the first hinge plate 431, the second hinge plate 432 and the base plate 433. The hinge portion 43 is connected to one end of the main body portion 41 through the first hinge plate 431 and the second hinge plate 432, so that the clearance space of the hinge portion 43 is connected to the first interface 411 of the main body portion 41. The first hinge plate 431 has a through-hole 434, and the second hinge plate 432 has a second hinge hole 435 on the side facing the clearance space. The axis of the first hinge hole 434 and the axis of the second hinge hole 435 are collinear, and the diameter of the first hinge hole 434 is the same as the diameter of the second hinge hole 435.

[0030] Reference Figure 1 and Figure 4The fixing part 42 is connected to the base plate 433 of the hinge part 43. The fixing part 42 has a mating hole 421. The shape of the mating hole 421 is designed according to the shape of the vehicle handlebar. In this embodiment, the shape of the mating hole 421 is circular. The fixing part 42 has a seam 422, which extends from the outside to the inside into the mating hole 421. The fixing part 42 is divided into a first seam end 423 and a second seam end 424 at the seam 422. The first seam end 423 is the thick end and the second seam end 424 is the thin end. The fixing part 42 is connected to the hinge part 43 through the first seam end 423. The first joint end 423 has a threaded hole on the side facing the joint 422, and the second joint end 424 has a through hole. The axis of the through hole is collinear with the axis of the threaded hole. The diameter of the through hole is larger than the diameter of the threaded hole. A screw with threads connected to the threaded hole passes through the through hole. The screw can tighten the first joint end 423 and the second joint end 424, so that the joint 422 is narrowed, thereby making the mating hole 421 clamp the handlebar of the vehicle, and realizing the fixation of the fixing seat 4 on the handlebar of the vehicle.

[0031] Reference Figure 2 and Figure 3 A hinge shaft 436 is provided between the first hinge hole 434 and the second hinge hole 435 of the hinge portion 43. The first brake lever 1 is hinged to the hinge portion 43 of the fixed base 4 via the hinge shaft 436. A push rod 5 is movably connected between the first brake lever 1 and the piston 413, and both ends of the push rod 5 are hinged ends. The clearance space of the hinge portion 43 is used to allow the first brake lever 1 and the push rod 5 to pass each other.

[0032] Reference Figure 3 When the first brake lever 1 is squeezed, it pushes the piston 413 via the push rod 5. The thrust is then transmitted to the brake pads of the wheel through the brake fluid, braking the wheel. When the first brake lever 1 is released, the restoring force of the brake pads is transmitted back to the piston 413 through the brake fluid, causing the piston 413, push rod 5, and first brake lever 1 to return to their original positions. During the above process, the cavity 410 maintains internal air pressure balance through an air chamber that communicates with the outside air.

[0033] Reference Figure 3 It should be noted that the diameter of the first interface 411 must be larger than the diameter of the push rod 5. This is to ensure that the first interface 411 can still connect the air chamber with the outside air after the push rod 5 passes through it, and also to ensure that the first interface 411 can avoid the push rod 5 from swinging during the movement and avoid jamming.

[0034] Reference Figures 2 to 4The second brake lever 2 and the anti-lock braking device (ABS) are mounted on the first brake lever 1. Specifically, the first brake lever 1 includes an integrally formed mounting part 11 and an operating part 12. The first brake lever 1 is hinged to the fixed base 4 via the mounting part 11. The operating part 12 is in the shape of a long handle to facilitate the user's squeezing of the first brake lever 1. The mounting part 11 includes a symmetrically arranged first mounting plate 111, a second mounting plate 112, and a top plate 113 connecting the first mounting plate 111 and the second mounting plate 112. A U-shaped mounting space is formed between the first mounting plate 111, the second mounting plate 112, and the top plate 113. The first mounting plate 111 is connected to the first hinge plate 431 via a hinge shaft 436, and the second mounting plate 112 is connected to the second hinge plate 432 via a hinge shaft 436. The ABS includes a drive member 31 and a cam 32. The cam 32 and the second brake lever 2 are mounted within the mounting space of the first brake lever 1.

[0035] Reference Figure 2 and Figure 3 One end of the second brake lever 2 is coaxially hinged to the first brake lever 1, and the other end of the second brake lever 2 is hinged to the push rod 5. The cam 32 is rotatably mounted within the mounting space, with its far repose point abutting the second brake lever 2. The cam 32 and the push rod 5 are respectively located on both sides of the second brake lever 2. The drive unit 31 is a motor, fixedly mounted outside the mounting space. The output shaft of the drive unit is coaxially connected to the cam 32 to drive the cam 32 to rotate. With the above configuration, when the first brake lever 1 is engaged, it drives the anti-lock braking system (ABS) and the second brake lever 2 to rotate around the hinge shaft 436. During rotation, the second brake lever 2 pushes the push rod 5 forward, thus achieving braking. When the wheel is about to lock up, the drive component 31 of the ABS starts to drive the cam 32 to rotate. During rotation, the second brake lever 2 can actively move backward towards the near rest point of the cam 32 under hydraulic pressure, and can also be pushed forward by the far rest point of the cam 32, causing the second brake lever 2 to swing repeatedly, ultimately achieving high-frequency intermittent braking and realizing the anti-lock braking effect. Furthermore, by placing the ABS externally on the vehicle handlebars, it achieves the anti-lock braking effect while also providing convenient disassembly and maintenance of the ABS.

[0036] In order for the drive unit 31 of the anti-lock braking system to be activated at the critical moment of wheel lock-up, a wheel speed sensor is usually installed at the wheel. The wheel speed sensor is then connected to the motor of the anti-lock braking system through a controller. This is existing technology, so it will not be described in detail.

[0037] Reference Figure 3In this embodiment, the cam 32 is a three-action cam 32, meaning it has three far-end points and three near-end points, so that the second brake lever 2 can respond with three oscillations for every one rotation of the cam 32. In other embodiments, the far-end points and near-end points of the cam 32 can be adjusted according to actual needs. If it is necessary to reduce the frequency of intermittent braking in anti-lock braking mode, the number of far-end points and near-end points is reduced; if it is necessary to increase the frequency of intermittent braking in anti-lock braking mode, the number of far-end points and near-end points is increased. In some embodiments, the cam 32 can also be replaced by an eccentric wheel, which is eccentrically connected to the output shaft of the drive member 31.

[0038] Reference Figure 2 and Figure 3 The fixing seat 4 has a cover plate 6 on the outside of the first hinge plate 431 of the main body 41 and the hinge part 43. The cover plate 6 covers the first hinge hole 434, thereby axially limiting the hinge shaft 436, so that the hinge shaft 436 is stably set between the first hinge shaft 436 and the second hinge shaft 436.

[0039] The implementation principle of the vehicle handlebar with an external anti-lock braking system in this embodiment is as follows: When braking, the user squeezes the first brake lever 1 on the vehicle handlebar. The first brake lever 1 pushes the push rod 5 through the anti-lock braking system and the second brake lever 2 inside it. The force of the push rod 5 is transmitted to the brake pads of the wheel through the brake fluid to achieve braking. When the wheel is in a critical lock-up state, the drive component 31 of the anti-lock braking system drives the cam 32 to rotate. Under the action of the cam 32 and the hydraulic pressure, the second brake lever 2 repeatedly abuts against the far rest point and near rest point of the cam 32, thereby achieving high-frequency intermittent braking and avoiding lock-up.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
