Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic brake products, specifically to a multifunctional universal brake lever. Background Technology

[0002] In vehicles such as bicycles, the device used to control the braking system is called a brake (commonly known as a brake lever). A brake lever is a handle used when braking. Brake levers are used in bicycle brake handles, children's bicycle brake handles, electric vehicle brake handles, motorcycle brake handles, etc.

[0003] With the continuous improvement of technology, the brakes used in bicycles and other vehicles on the market have gradually replaced the traditional brakes that relied on solid media such as steel wires for transmission, and have been replaced by hydraulic brakes that use liquid media such as oil as the transmission medium. The most representative of these is the hydraulic brake.

[0004] The principle of a hydraulic brake is to connect one end of the brake hose to the output end of the internal oil circuit of the brake lever seat, while the other end of the brake hose is connected to the disc brake disc. Pressing the lever will activate and push the internal oil circuit piston rod, so that the pressure in the oil circuit will act on the disc brake disc through the brake hose, thus forming the operation of disc braking.

[0005] Furthermore, existing hydraulic brakes on the market undergo structural modifications to enhance their versatility, enabling compatibility with various vehicle types, including bicycles, electric bikes, and motorcycles. These modifications include making the brake lever travel adjustable.

[0006] Chinese patent application ZL202422671325.4 discloses: "A hydraulic brake with adjustable stroke, comprising a brake body, a piston rod, a handle, and a transmission rod; further comprising a cylinder liner and an adjusting member; the cylinder liner is movably disposed within a pressure cylinder, the cylinder liner having at least a first position state and a second position state relative to the pressure cylinder, and the movement of the cylinder liner can cause the piston rod to move relative to the pressure cylinder, thereby changing the set starting position of the piston rod; the adjusting member is movably connected to the brake body, the adjusting member comprising an operating end and an actuating end, the actuating end of the adjusting member abutting against the cylinder liner; this utility model achieves the purpose of adjusting the brake's idle stroke by adjusting the cylinder liner to move it, thereby causing the transmission rod and piston rod that cooperate with the cylinder liner to move accordingly, thereby changing the set starting position of the piston rod, and thus achieving the purpose of adjusting the brake's idle stroke, and since the cylinder liner and piston rod move together, the cooperation relationship between the two will not change."

[0007] However, including the solutions described in the aforementioned patents, existing general-purpose hydraulic brakes all have a problem: the handlebars of existing bicycles are generally quite simple, and there is no interference with the installation of the brake lever. However, on electric bikes and motorcycles, the handlebars themselves have many accessories installed. The presence of these accessories will compress the installation space of the brake lever, causing the brake lever to interfere with these accessories during installation. Summary of the Invention

[0008] In order to overcome the shortcomings of existing universal brake levers that interfere with handlebar accessories when installed on electric vehicles and motorcycles, making installation impossible, this utility model provides a multifunctional universal brake lever.

[0009] The technical solution of this utility model to solve its technical problem is: a multifunctional universal brake lever, comprising:

[0018] Furthermore, a first groove is recessed on the rear side of the front seat, a second groove is formed on the front side of the rear seat, and a third groove is formed on the pad.

[0019] When the pad is in the detached position relative to the mounting base, the handlebar mounting space is formed by the first groove and the second groove;

[0020] When the pad is in the assembled position relative to the mounting base, the handlebar mounting space is formed by the combination of the third groove and the second groove.

[0021] Furthermore, the pad includes a mating part, and the third groove is formed on the rear side of the mating part. The front side of the mating part is also provided with a mating protrusion. When the pad is in the assembled state relative to the mounting base, the mating protrusion can be engaged and mated into the first groove of the front seat body.

[0022] Furthermore, the front seat body is provided with a first wing plate protruding from the upper and lower sides, the rear seat body is provided with a second wing plate protruding from the upper and lower sides, and the pad is provided with a third wing plate protruding from the upper and lower sides. The first wing plate is provided with a first threaded hole, and the second and third wing plates are provided with through holes. It also includes connecting bolts.

[0023] When the pad is in the disassembled state, the connecting bolt passes through the through hole on the second wing and is threaded into the first threaded hole of the first wing;

[0024] When the pad is in the assembled state, the connecting bolt passes through the through holes on the second wing plate and the third wing plate in sequence and then is threaded into the first threaded hole of the first wing plate.

[0025] Furthermore, the top of the pad is provided with an accessory mounting post, and the accessory mounting post is provided with a mounting hole, the accessory mounting post extending above the mounting base.

These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0049] Example 1

[0050] Combination Figures 1 to 7 A multifunctional universal brake lever is shown, comprising a brake body 1, a grip 2, a mounting base, and a pad 6. The grip 2 is rotatably connected to the brake body 1. The mounting base includes a front seat 3 and a rear seat 4, wherein the front seat 3 is connected to the brake body 1, and the front seat 3 and the rear seat 4 are connected to form a handlebar mounting space 5 through which a handlebar 100 passes. The pad 6 is disposed between the front seat 3 and the rear seat 4, and the pad 6 has at least a detached state and an assembled state relative to the mounting base. When the mounting base is assembled on the handlebar 100 and the pad 6 is in the detached state, a first gap 7 is formed between the brake body 1 and the handlebar 100. When the mounting base is assembled on the handlebar 100 and the pad 6 is in the assembled state, the pad 6 can be placed between the front seat 3 and the handlebar 100, and a second gap 8 is formed between the brake body 1 and the handlebar 100. The width of the second gap 8 is greater than the width of the first gap 7.

[0051] Combination Figures 1 to 3 As shown, in this embodiment, the front seat 3 has a first groove 9 recessed on its rear side, the rear seat 4 has a second groove 10 on its front side, and the pad 6 has a third groove 11. When the pad 6 is in a disassembled position relative to the mounting base, the first groove 9 and the second groove 10 are combined to form the handlebar mounting space 5. When the pad 6 is in an assembled position relative to the mounting base, the third groove 11 and the second groove 10 are combined to form the handlebar mounting space 5.

[0052] Combination Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the pad 6 includes a mating part 12, and the third groove 11 is opened on the rear side of the mating part 12. The front side of the mating part 12 is also provided with a mating protrusion 13. When the pad 6 is in the assembled state relative to the mounting base, the mating protrusion 13 can be fitted into the first groove 9 of the front seat body 3.

[0053] Combination Figure 2 and Figure 5 As shown, in this embodiment, the front seat 3 has a first wing plate 14 protruding from its upper and lower sides, the rear seat 4 has a second wing plate 15 protruding from its upper and lower sides, and the pad 6 has a third wing plate 16 protruding from its upper and lower sides. The first wing plate 14 has a first threaded hole 17, and the second wing plate 15 and the third wing plate 16 have through holes 18. A connecting bolt 19 is also included. When the pad 6 is in a disassembled state, the connecting bolt 19 passes through the through hole 18 on the second wing plate 15 and is threaded into the first threaded hole 17 on the first wing plate 14. When the pad 6 is in an assembled state, the connecting bolt 19 passes through the through holes 18 on the second wing plate 15 and the third wing plate 16 in sequence and is threaded into the first threaded hole 17 on the first wing plate 14.

[0054] Among them, such as Figure 5 As shown in the figure, in this embodiment, the top of the pad 6 is also provided with an accessory mounting post 20, and the accessory mounting post 20 is also provided with a mounting hole 21, and the accessory mounting post 20 extends out from above the mounting base.

[0055] Combination Figures 1 to 4 As shown, in this embodiment, the front seat 3 is integrally formed on the brake body 1.

[0056] Among them, such as Figure 6 As shown in the figure, a pressure cylinder 22 is provided inside the brake body 1 in this embodiment. A piston rod 23 is movably inserted inside the pressure cylinder 22. A transmission rod 24 is provided between the grip 2 and the piston rod 23. The front end of the transmission rod 24 is connected to the grip 2, and the rear end of the transmission rod 24 is connected to the piston rod 23. By pressing the grip 2, the transmission rod 24 can be moved, thereby pushing the piston rod 23 to move inside the pressure cylinder 22.

[0057] Among them, such as Figure 7 As shown in the figure, in this embodiment, a connecting post 25 is rotatably connected to the grip 2. The connecting post 25 is provided with a second threaded hole 26. The transmission rod 24 is also provided with a threaded part 27. The connection between the grip 2 and the transmission rod 24 is realized through the threaded engagement of the threaded part 27 and the second threaded hole 26.

[0058] Among them, such as Figure 7As shown in the figure, an adjustment knob 28 is also provided on the front end of the transmission rod 24 in this embodiment. By rotating the adjustment knob 28, the transmission rod 24 can be driven to rotate, and the transmission rod 24 can be moved relative to the handle 2.

[0059] In this embodiment, the gap between the brake body 1 and the handlebar 100 varies depending on the state of the pad 6 relative to the mounting base. When operating the handlebar, the operator typically covers the handlebar 100 and the grip 2 of the brake lever with their hand, using one or more fingers to hold the handlebar 100 and then pressing the grip 2 with the remaining fingers. Since the brake lever causes a change in the positional relationship between the grip 2 and the handlebar 100, the user can adjust the position of the grip 2 relative to the handlebar 100 after adjusting the position of the brake body 1 relative to the handlebar 100. During adjustment, the adjustment knob 28 on the transmission rod 24 is rotated to move the transmission rod 24 relative to the grip 2. Since the grip 2 is rotatably connected to the brake body 1, the movement of the transmission rod 24 causes the grip 2 to rotate, thereby adjusting the positional relationship between the grip 2 and the handlebar 100.

[0060] This embodiment presents two installation methods:

[0061] When the brake lever of the embodiment is installed on the handlebar 100 without other accessories, the front seat 3 on the brake body 1 is directly aligned with the front side of the handlebar 100, and the first groove 9 on the front seat 3 is fitted to the surface of the handlebar 100. Then the rear seat 4 is fastened to the handlebar 100 from the rear side, so that the second groove 10 on the rear seat 4 is fitted to the surface of the handlebar 100. Finally, the connecting bolt 19 is passed through the through hole 18 on the rear seat 4 and tightened into the threaded hole on the front seat 3. At this point, the brake body 1 is installed on the handlebar 100, and at this time, a first gap 7 is formed between the brake body 1 and the handlebar 100.

[0062] When the brake lever of this embodiment is installed on the handlebar 100 with other accessories, firstly, align the mating part 12 of the pad 6 with the front seat 3 on the brake body 1, then fit the mating protrusion 13 on the mating part 12 into the first groove 9 of the front seat 3, and then fasten the brake body 1 together with the pad 6 on it to the front side of the handlebar 100, so that the third groove 11 on the pad 6 fits against the surface of the handlebar 100. Next, fasten the rear seat 4 from the rear side of the handlebar 100 to the handlebar 100, so that the second groove 10 on the rear seat 4 fits against the handlebar 100. The surfaces are fitted together, and finally the connecting bolt 19 is passed through the through hole 18 on the rear seat body 4 and the pad 6 and tightened into the threaded hole on the front seat body 3. At this point, the brake body 1 is installed on the handlebar 100. At this time, the pad 6 is placed between the handlebar 100 and the front seat body 3 to increase the distance between the brake body 1 and the handlebar 100, so that a second gap 8 is formed between the brake body 1 and the handlebar 100. This second gap 8 can provide enough space to accommodate other accessories on the handlebar 100 to avoid interference between the brake body 1 and other accessories.

[0063] The advantage of this embodiment is that, thanks to the removable pad, the brake lever can be installed on the handlebar in two different ways, thus making it compatible with various vehicle types such as bicycles, electric vehicles, and motorcycles.

[0064] Example 2

[0065] Reference Figure 8 As shown, this embodiment illustrates the positional relationship between the brake body and other accessories when the brake lever is actually installed on a handlebar with other accessories in Embodiment 1 above.

[0066] In this embodiment, since the pad 6 is in the assembled position, when the mounting seat is connected to the handlebar 100, the pad 6 is placed between the front seat 3 and the handlebar 100, which increases the distance between the brake body 1 and the handlebar 100 and forms a second gap 8. As shown in the figure, the second gap 8 can accommodate other accessories on the handlebar 100, so that there is no interference between the brake body 1 and other accessories on the handlebar 100.

[0067] The remaining structures, methods, and advantages of this embodiment are consistent with those of Embodiment 1 above, and will not be repeated here.

[0068] The above specific embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
