Description

Technical Field

[0001] This utility model relates to the field of scooter structure technology, and in particular to a scooter with hydraulic brakes. Background Technology

[0002] Hydraulic brakes on scooters transmit power through incompressible brake fluid with minimal power loss, achieving powerful and reliable braking with minimal hand force, making them particularly suitable for high-speed riding or when carrying heavy loads. Hydraulic brakes provide a smooth feel, with a linear ratio between pinch force and braking force, facilitating precise control such as slight deceleration or intermittent braking, preventing wheel lock-up and skidding due to sudden braking. Scooters require riders to stand; during emergency braking, inertia can cause the body to lean forward violently, easily leading to a front flip or a skid due to wheel lock-up. Hydraulic brakes allow for precise control of braking force, reducing the risk of forward falls due to excessive braking.

[0003] The paper CN217125039U, entitled "An Integrated DIY Mini Hydraulic Brake," addresses the issue that existing hydraulic brake pads are not durable, inconvenient to replace, and time-consuming to replace. It proposes a solution by incorporating a detachable lower pump assembly that allows for easy replacement of the brake pads.

[0004] However, in actual use, the steering column of the scooter can be extended to adjust the height of the scooter so that it can be used by riders of different heights, especially children. People of different heights have relatively large differences in the size of their hands. Therefore, when squeezing the hydraulic brake, it is not comfortable to hook the brake lever with your fingers. You may need to use your whole palm to "reach" or even "move" your hand to touch the brake lever. This will seriously sacrifice the grip on the handlebars and easily lead to instability of the hands when riding or turning. Utility Model Content

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a scooter with hydraulic brake, including a frame, a handlebar mounted on the frame, and a brake part fixed to the handlebar, the brake part including: The brake lever is L-shaped. One end is fitted with a limit ring by bolts. The size of the limit ring can be adjusted by bolts to fix it to the handlebars. The other end has an integral transmission pipe for transmitting hydraulic oil. A brake lever is hinged to the brake handle; pressing the brake lever applies the brakes. The adjustment unit, installed inside the brake handle, is used to squeeze and reset the brake fluid; The reset unit is located between the brake lever and the brake handle, and is used to reset the brake lever after it is pressed.

[0007] A further preferred embodiment of this utility model is: an oil reservoir is fixed to the outside of the transmission pipe, and the oil reservoir is connected to the inside of the transmission pipe through a pipe hole.

[0008] A further preferred embodiment of this utility model is: the adjustment unit includes a limiting layer, a threaded rod, a pressure plate, a shaft plug, a sealing ring, and a return spring. The limiting layer is rotated and clamped inside the brake lever end. The shaft plug is sleeved inside the transmission tube. The sealing ring is embedded in the outer wall of the shaft plug to seal between the shaft plug and the transmission tube. The return spring is sleeved inside the transmission tube to push the shaft plug back to its original position. The threaded rod passes through the limiting layer and is threadedly connected to the limiting layer. The pressure plate is fixed to the end of the threaded rod and is used to abut against the end of the shaft plug.

[0009] A further preferred embodiment of this utility model is: the outer wall of the return spring contacts the inner wall of the transmission tube, and the outer wall of the shaft plug near one end of the return spring has a cavity, which is used to prevent the pipe hole of the oil can from being covered.

[0010] A further preferred embodiment of this utility model is: the brake lever is L-shaped, and its hinge position with the brake handle is located at the bent part of the brake lever. By moving the long axis part of the brake lever, the short axis part is squeezed inward to press the adjustment unit.

[0013] A further preferred embodiment of this utility model is: the brake handle has an upward through-hole, the through-hole being located at the lower end of bolt one, and the brake handle also has an upward threaded opening, with bolt two threadedly connected inside the threaded opening.

[0014] Compared with the prior art, the advantages of this utility model are: 1. By rotating the threaded rod, the initial position of the brake lever relative to the handlebar can be continuously adjusted, allowing users with different hand sizes and grip habits to easily hook their fingers onto the brake lever without changing their grip posture or moving their hands significantly, thus improving overall control of the handlebar while riding.

[0015] 2. The return spring always applies a slight tension to the brake lever to ensure that the pressure plate and the axle plug remain in contact, eliminating the gap caused by adjustment, and preventing the brake lever from shaking and generating noise due to vibration during riding. At the same time, the brake lever is squeezed when braking to achieve the braking effect.

[0016] 3. The return spring has a hook-shaped design at both ends, which allows for quick disassembly and assembly, making it convenient to replace fatigued springs after long-term use and extending the overall lifespan. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0022] This embodiment mainly describes a scooter with hydraulic brakes. Please refer to [link / reference]. Figures 1-6 Specifically, as follows: In actual use, the steering column of the scooter can be extended or retracted to adjust the height of the scooter to suit riders of different heights. When manually squeezing the hydraulic brake, it may not be comfortable to hook the brake lever with one's fingers; one may need to use the entire palm to "reach" or even "move" the hand to touch the brake lever. To address this problem, a hydraulic brake scooter is proposed, comprising a frame 1, a handlebar 2 mounted on the frame 1, and a brake unit 3 fixed to the handlebar 2. The brake unit 3 includes: The brake lever 31 is L-shaped. One end of it is fitted with a limit ring 32 by bolts. The size of the limit ring 32 can be adjusted by bolts and is used to fix it to the handlebar 2. The other end of it has an integral transmission pipe 33 for transmitting hydraulic oil. Brake lever 35 is hinged to brake handle 31. Pressing brake lever 35 applies the brake. The adjustment unit 36 ​​is installed inside the brake handle 31 and is used to squeeze and reset the brake fluid; The reset unit 37 is disposed between the brake lever 35 and the brake handle 31 and is used to reset the brake lever 35 after it is pressed.

[0023] Specifically, the brake handle 31 is an existing structure, and the limiting ring 32 at one end can be split into two and assembled by bolts so that the limiting ring 32 can be fixed to the handlebar 2. The brake lever 35 is an L-shaped rod structure. When in use, the brake lever 35 is manually squeezed to compress the adjusting unit 36. The hydraulic oil moves in the transmission pipe 33 to achieve the braking effect. It should be noted that how the hydraulic oil moves and how braking is performed are existing technologies.

[0024] like Figure 2 As shown, an oil reservoir 34 is fixed to the outside of the transmission pipe 33, and the oil reservoir 34 is connected to the inside of the transmission pipe 33 through a pipe hole.

[0025] Specifically, the oil reservoir 34 is existing technology. The oil reservoir 34 is usually placed directly above the transmission pipe 33, and the two are connected by a channel. When the regulating unit 36 ​​squeezes, it will squeeze and close the channel to provide backup brake fluid for the brake structure and automatically compensate for changes in the amount of oil in the system caused by brake pad wear or temperature changes, while preventing air from entering.

[0026] like Figures 3-4As shown, the adjustment unit 36 ​​includes a limiting layer 361, a threaded rod 362, a pressure plate 363, a shaft plug 364, a sealing ring 365, and a return spring 367. The limiting layer 361 is rotated and clamped on the inner side of the end of the brake lever 35. The shaft plug 364 is sleeved inside the transmission tube 33. The sealing ring 365 is embedded in the outer wall of the shaft plug 364 to seal the shaft plug 364 and the transmission tube 33. The return spring 367 is sleeved inside the transmission tube 33 to push the shaft plug 364 back to its original position. The threaded rod 362 passes through the limiting layer 361 and is threadedly connected to the limiting layer 361. The pressure plate 363 is fixed to the end of the threaded rod 362 and is used to abut against the end of the shaft plug 364.

[0027] Specifically, when the piston 364 and its outer sealing ring 365 slide inside the transmission pipe 33, they can squeeze the hydraulic oil, causing the hydraulic oil to move along the transmission pipe 33. The return spring 367 generates a reverse force after the piston 364 moves, pushing the piston 364 back. It should be noted that when the piston 364 is pushed back, it is pushed back to the very end, and the oil reservoir 34 is in a state of communication with the inside of the transmission pipe 33.

[0028] The position of the threaded rod 362 can be changed by rotating it with the help of an external tool. It should be noted that the position of the outwardly extending end of the piston 364 remains unchanged. After the extension and retraction of the pressure plate 363 changes, the brake lever 35 has a gap that allows for reciprocating movement. Squeezing the brake lever 35 within this gap will not compress the piston 364. Therefore, through the reset unit 37, even if the threaded rod 362 is adjusted, the pressure plate 363 can still maintain a slight compression on the outwardly extending end of the piston 364. During slight compression, the position of the piston 364 remains unchanged. It should also be noted that the limiting layer 361 is rotatable. During the process of the brake lever 35 being squeezed, since the brake lever 35 is in a hinged state, the brake lever 35 rotates along the hinge position. The rotatability of the limiting layer 361 reduces the distance between the threaded rod 362 and the pressure plate 363 as the brake lever 35 rotates, allowing the pressure plate 363 to push the shaft plug 364 as straight as possible. It should be noted that even if the threaded rod 362 and the pressure plate 363 rotate with the brake lever 35, the pressure plate 363 can still push the shaft plug 364 because it increases the contact area. It should also be noted that because the pressure plate 363 has a relatively large area, it is located in the inward recessed part of the brake handle 31. During riding, the position of the threaded rod 362 and the pressure plate 363 will not deviate. Even if deviate, it will still be located in the inward recessed part of the brake handle 31.

[0029] like Figure 4As shown, the outer wall of the return spring 367 contacts the inner wall of the transmission tube 33, and the outer wall of the plug 364 near one end of the return spring 367 has a cavity 366, which is used to prevent the tube hole of the oil can 34 from being covered.

[0030] Specifically, the function of the cavity 366 is to prevent the pipe hole of the oil can 34 from being covered, while the shaft plug 364 will cover the pipe hole of the oil can 34 when it moves. This is the existing technology for installing the oil can 34.

[0031] like Figures 3-5 As shown, the brake lever 35 is L-shaped, and its hinge position with the brake handle 31 is located at the bent part of the brake lever 35. By moving the long axis of the brake lever 35, the short axis of the brake lever 35 is pressed inward to squeeze the adjusting unit 36.

[0032] Specifically, the brake lever 35 forms a lever structure through the hinge position. When in use, its long axis is the part that is manually pinched, and the short axis part squeezes the adjustment unit 36. Thus, only a relatively small force is needed to drive the adjustment unit 36 ​​to work.

[0033] like Figures 5-6 As shown, the reset unit 37 includes bolt 371, bolt 373, and reset spring 375. Bolt 371 is threaded to the short shaft of brake lever 35, and bolt 373 is threaded to brake handle 31. Return spring 375 is installed between bolt 371 and bolt 373 to generate tension on brake lever 35.

[0034] Specifically, the main function of the reset unit 37 is to use the reset spring 375 to make the pressure plate 363 abut against the shaft plug 364, thereby generating a pulling force on the brake lever 35 and ensuring that the pressure plate 363 abuts against the shaft plug 364 when adjusting the threaded rod 362.

[0035] like Figure 6 As shown, a notch 372 is formed on the outer wall of bolt 371, and a notch 374 is formed on the outer wall of bolt 373. The two ends of the return spring 375 are hook-shaped structures, which are hooked into the notch 372 and the notch 374 respectively. The return spring 375 is always in a stretched state.

[0036] The hook-shaped structures at both ends of the second return spring 375 can be directly hooked into the first recess 372 and the second recess 374, which makes it easy to fix the second return spring 375 and also easy to disassemble and replace.

[0037] like Figure 5 As shown, the brake handle 31 has a through-hole 311 extending upwards, which is located at the lower end of bolt 371. The brake handle 31 also has a threaded opening 312 extending upwards, and bolt 373 is threaded into the threaded opening 312.

[0038] Specifically, the through-hole 311 is used for the insertion of bolt 371 through the through-hole 311 and for threading with the brake lever 35, which facilitates installation. Bolt 373 can be directly connected from bottom to top into the threaded opening 312.

[0039] Working principle: By hooking the brake lever 35 with a finger, the pressure plate 363 pushes the shaft plug 364, compressing the return spring 367, causing hydraulic oil to move along the transmission pipe 33, thus activating the brake. It should be noted that the brake activation is existing technology. The oil reservoir 34 is also existing technology, providing backup brake fluid and automatically compensating for changes in system fluid levels due to brake pad wear or temperature variations, while preventing air from entering; this is also existing technology.

[0040] By rotating the threaded rod 362, the position of the brake lever 35 can be adjusted, changing the distance between it and the handlebar 2. This allows the rider to comfortably hook the brake lever 35 with their fingers, thereby relatively improving the grip on the handlebar 2.

[0041] It should be noted that, under the action of the reset unit 37, the pressure plate 363 and the shaft plug 364 are always kept in contact, preventing the brake lever 35 from being loosened after adjusting the threaded rod 362, thus reducing vibrations that could cause the brake lever 35 to vibrate during riding. It should also be noted that the bolts 371 and 373, along with the reset spring 375 between them, can be replaced simply by rotating them. The reset spring 375 has a hook-shaped structure at both ends, and is a commonly used spring, making it easy to replace. Timely replacement prevents elastic fatigue from occurring during prolonged use, which could lead to vibrations causing the brake lever 35 to vibrate during riding.
