Description

Technical Field

[0001] This application relates to the field of bicycle braking devices, and in particular, to a braking system and a bicycle. Background Art

[0002] As a means of transportation, bicycles play an important role in people's daily lives. The braking mechanism is an essential component to ensure the reliable operation of bicycles and is widely used in bicycles.

[0003] Conventional bicycle brakes usually have a rotating seat provided on the frame, and the braking module is fixed by rotatably connecting the rotating shaft on the braking module with the rotating seat. At the same time, there is an adjusting screw on the brake block, and the angle of the brake block is adjusted by the adjusting screw. However, it is difficult to adjust the brake block to positions such as rotation, pitching, and front-back, resulting in poor braking effect and abnormal noises. Similarly, disc brakes also have similar problems, that is, the position of the brake caliper cannot be adjusted in any direction, angle, and position. Summary of the Utility Model

[0007] By adopting the above technical solution, the brake seat includes an installation part and a connection part, and is connected to the vehicle frame through the installation part, which is convenient for installation on the vehicle frame and can be adjusted in position at the same time. The brake module is connected to the brake seat through the connection part, which is convenient for adjusting the position of the brake module. Moreover, when the brake module is installed through the guiding base, the installation direction can be rotated, which is convenient for adjusting the braking part of the brake to the most suitable position and improving the braking effect. At the same time, pulling the brake cable reduces the distance between the transmission part and the guiding base, driving the driving part to drive the braking part to contact the surface of the wheel rim, playing a braking role. By reducing the distance between the transmission part and the guiding base, the braking stability can be improved; when not braking, the transmission part is far away from the guiding base, providing space for the rotation of the transmission part.

[0008] Preferably, the connection part is arranged on the installation part, and the connection part can freely rotate relative to the installation part along the vehicle moving direction, including: the installation part includes a first installation part and a second installation part, and the first installation part and the second installation part are arranged on the vehicle at intervals; both ends of the connection part are respectively arranged on the first installation part and the second installation part; first long slot holes are respectively arranged at the positions where both ends of the connection part are connected to the installation part, and the first long slot holes extend along the axial direction of the vehicle.

[0010] Preferably, the brake module further includes a mounting seat sleeved on the connecting rod. The mounting seat is located between the guiding base and the connection part. An arc-shaped circular groove is formed on one side of the mounting seat close to the guiding base, and an arc-shaped convex block adapted to the arc-shaped circular groove is arranged on one side of the guiding base in contact with the mounting seat.

[0011] By adopting the above technical solution, the mounting seat is arranged between the guiding base and the connection part. As an adjustable interface, it makes the angle and position adjustment of the brake structure more flexible, and can easily change the alignment and contact angle of the brake components to meet different usage requirements. Moreover, the diameter of the mounting hole is larger than the diameter of the screw rod, and there is an adjustment space for the screw rod in the mounting seat, which is convenient for better adjusting the brake structure to ensure that the brake structure is in the best working angle and position, thereby enhancing the braking effect. At the same time, the arc-shaped circular groove on the mounting seat cooperates with the arc-shaped convex block on the guiding base, increasing the contact area. After adjusting the position of the brake module, it is not easy to loosen or shift, enhancing the stability of the overall structure, and keeping the brake module in the best position to the greatest extent, further improving the braking effect.

[0012] Preferably, one end of the transmission part is provided with an installation part for fixing the brake wire, and the installation part fixes the brake wire at one end of the transmission part away from the driving part.

[0013] By adopting the above technical solution, an installation part for fixing the brake wire is provided at one end of the transmission part, aiming to provide a stable and efficient way to fix the brake wire, so as to ensure that the braking action can be accurately and quickly transmitted to the driving part, thereby achieving a reliable braking effect.

[0014] Preferably, a wire groove for the brake wire to pass through is opened on the guiding base, and the wire groove includes a fixing block for fixing the outer skin of the brake wire and an arc groove with the same diameter as the brake wire core.

[0015] By adopting the above technical solution, by opening a wire groove on the guiding base, it can play a guiding role in the movement of the brake wire, preventing the brake wire from moving to other positions during use and affecting other structures. Moreover, the wire groove is opened into an arc groove, with a simple structure, and when in use, only the brake wire needs to be placed in it.

[0016] Preferably, it further includes a reset part, and the reset part is used to reset the braking part from the braking position to the release position away from the surface of the wheel rim. The reset part is set as a torsion spring, one end of the torsion spring is clamped on the guiding base, and the other end is connected to the transmission part.

[0017] By adopting the above technical solution, when braking is completed and the acting force of the brake wire on the transmission part is removed, the reset part makes the braking part move away from the wheel rim and return to the release position, reducing the occurrence of the situation where the braking part is locked with the wheel rim, enabling the vehicle to continue moving forward. Setting the reset part as a torsion spring facilitates the transmission part to quickly and accurately return to the initial position after braking, and using a torsion spring has a compact design and a small volume, with a compact structure and convenient space saving.

The driving part drives the braking part to move, and the braking part moves along the guiding groove on the guiding base in a direction away from the guiding base and approaches the wheel rim. The gear teeth on the driving part cooperate with the rack on the braking part, and the braking part can be limited in the limiting groove of the guiding base to avoid the falling off of the braking part.

[0020] Preferably, the side of the driving part away from the gear teeth is set as a U-shaped plate, and the U-shaped plate is arranged on both sides of the guiding base and is rotatably connected to the guiding base.

[0021] By adopting the above technical solution, the position where the driving part is connected to the guiding base is set as a U-shaped plate structure and is arranged on both sides of the guiding base. When the driving mechanism is driven by the brake wire, the driving mechanism is more stable.

[0022] Preferably, mounting grooves are formed at the mounting positions of the guiding base and the U-shaped plate. The U-shaped plate is arranged in the mounting grooves. The mounting grooves are set as arc-shaped, and limiting plates for restricting the rotation of the U-shaped plate are arranged on both sides of the arc.

[0023] By adopting the above technical solution, by arranging the U-shaped plate in the arc-shaped mounting groove, the space can be utilized more efficiently. Limiting plates are arranged on both sides of the arc. When the U-shaped plate rotates around the rotating shaft, the gear teeth and the rack are not likely to fall off due to excessive rotation, improving the structural safety.

[0024] In a second aspect, the present application also provides a bicycle, which includes a braking system, a frame, wheels, and a seat. It is characterized in that the braking system includes a braking structure, and the braking structure is any one of the first aspect.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

At the same time, pulling the brake wire reduces the distance between the transmission part and the guiding base, driving the driving part to drive the braking member to contact the surface of the wheel rim, playing a braking role. By reducing the distance between the transmission part and the guiding base, the braking stability can be improved; when not braking, the transmission part is far from the guiding base, providing space for the rotation of the transmission part.

[0033] The following further describes this application in detail with reference to the attached Figures 1-6 drawings.

[0034] An embodiment of this application discloses a braking system. Referring to Figure 1 a schematic diagram of a braking system shown, the braking system includes a brake seat 11 and a brake module 12.

[0035] The brake seat 11 is fixedly connected to the vehicle frame 2. In this solution, the brake module 12 is installed through the brake seat 11, so as to flexibly adjust the position of the brake module 12 relative to the wheel 3 or the brake disc 4, and achieve a more relaxed / convenient braking purpose.

[0036] In an embodiment of this application, the brake seat 11 includes an installation part 111 and a connection part 112. The installation part 111 is connected to the vehicle frame 2. The connection part 112 is arranged on the installation part 111, and the connection part 112 can freely rotate relative to the installation part 111 along the vehicle moving direction. The brake module 12 is arranged on the connection part 112, and when the brake module 12 is connected to the connection part 112, it can freely rotate along the axial direction. Finally, the position of the brake module 12 relative to the wheel 3 or the brake disc 4 of the vehicle can be freely adjusted.

[0037] Specifically, the installation part 111 includes a first installation part 1111 and a second installation part 1112. The first installation part 1111 and the second installation part 1112 are arranged on the vehicle at intervals. Both ends of the connection part 112 are respectively arranged on the first installation part 1111 and the second installation part 1112; first long slot holes 1121 are respectively arranged at the positions where both ends of the connection part 112 are connected to the installation part 111. The first long slot holes 1121 extend along the axial direction of the vehicle.

[0038] In a specific embodiment, when the connection part 112 is provided with the first long slot holes 1121; the brake module 12 is connected to the brake seat 11 through the connection part 112. Due to the existence of the first long slot holes 1121, it can move freely along the vehicle moving direction and the vehicle axial direction.

[0039] Of course, setting the first long slot 1121 on the connecting portion 112 as described above is only one implementation manner in the specific embodiments of the present application. In another embodiment of the present application, the first long slot 1121 may also be set on the mounting base 111. That is, a hole similar to the current first long slot 1121 is respectively provided on the first mounting portion 1111 and the second mounting portion 1112. The connecting portion 112 is mounted through the first long slots 1121 on the two mounting portions 111. In addition, there are many structures that can achieve the above free movement as described above. What is given here in the present application is only an example of the present application. All the ways that can achieve the above free mounting structure are within the protection scope of the present application.

[0040] The brake module 12 includes a guiding base 121. A braking member 122 is provided at one end of the guiding base 121. The end of the guiding base 121 opposite to the braking member 122 is connected to the connecting portion 112, and the mounting position and direction of the guiding base 121 and the connecting portion 112 are adjustable.

[0041] Specifically, a connecting rod 123 is provided at the end of the guiding base 121 opposite to the braking member 122. A second long slot 1122 is formed in the middle of the connecting portion 112. The second long slot 1122 extends along the moving direction of the vehicle.

[0042] The end of the guiding base 121 opposite to the braking member 122 is connected to the connecting portion 112, and the mounting position and direction of the guiding base 121 and the connecting portion 112 are adjustable. Specifically, the connecting rod 123 is arranged through the long slot 1122.

[0043] Furthermore, a screw rod passing through the second long slot 1122 is provided at the position where the guiding base 121 is mounted to the connecting portion 112. The screw rod is used as the connecting rod 123 in the embodiment of the present application. And the screw rod is fixed to the connecting portion 112. The mounting position and direction of the screw rod and the second long slot 1122 are adjustable. The brake module 12 further includes a braking member 122 movably mounted on the guiding base 121 for braking the vehicle wheel hub, and a driving mechanism 125 movably mounted on the guiding base 121 for driving the braking member 122 to move towards the wheel hub. The driving mechanism 125 includes a transmission portion 1251 connected to the brake cable and a driving portion for driving the braking member 122. Through the optimization of the structural design and the cooperation relationship, the brake structure can be flexibly adjusted under different use conditions while maintaining stability and reliability.

[0044] Specifically, the position of the first long slot hole 1121 can be finely adjusted by adjusting screws. For example, the size of the first long slot hole 1121 is 10 mm × 2 mm (width × length), and the diameter of the screw is 4 mm. This long slot hole design makes it easier to adjust the position of the brake seat 11 on the frame 2. The material of the mounting portion 111 can be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance. For example, the high-strength steel material can be selected as 45# steel, and the aluminum alloy can be selected as 6061-T6 aluminum alloy. Both materials have good mechanical properties and corrosion resistance. The connecting portion 112 is used to connect the brake module, and a second long slot hole 1122 is provided at the position where the connecting portion 112 is connected to the brake module 12. The position of the second long slot hole 1122 is also adjusted by adjusting screws. For example, the size of the second long slot hole is 20 mm × 4 mm (width × length), and the diameter of the screw is 6 mm. This long slot hole design makes it more convenient to adjust the position of the brake module 12. The material of the connecting portion 112 can also be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance.

[0045] The guiding base 121 is fixed to the connecting portion 112 by a screw rod, and the position and direction are adjusted through the screw rod and the second long slot hole. Specifically, the length of the screw rod is 50 mm, and the thread diameter is 6 mm. The position and direction of the installation of the second long slot hole and the screw rod are adjustable, and this design makes the position adjustment of the brake module 12 more flexible. The material of the guiding base 121 can be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance. For example, the high-strength steel material can be selected as 45# steel, and the aluminum alloy can be selected as 6061-T6 aluminum alloy.

[0046] On one side of the guiding base 121 facing the braking member 122, a guiding slot 1221 matching the braking member 122 is provided. The main function of the guiding slot 1221 is to limit the sliding path of the braking member 122 on the guiding base 121 and prevent the braking member 122 from shifting or falling off during movement. For example, the size of the guiding slot can be designed as 10 mm × 20 mm (width × length). The guiding slot 1221 can be an integral structure with the guiding base 121, or the guiding slot 1221 and the guiding base 121 can be connected together as two different modules. When the guiding slot 1221 is an independent part, its material can be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance.

[0047] Although not shown in the figure, the brake system in the embodiment of the present application necessarily further includes a brake lever and a brake cable, so as to drive the brake cable through the brake lever to drive the braking member 122 in the brake module 12 to move.

[0048] Based on this, in the embodiments of the present application, a wire groove 126 for the brake wire to pass through may also be provided on the guiding base 121. The wire groove 126 may be composed of two parts, that is, it includes a fixing block (not shown in the figure) for fixing the outer skin of the brake wire and an arc groove 1261 having the same diameter as the brake wire core. The wire groove is set as the arc groove 1261. The design of the wire groove 126 enables the brake wire not to interfere with the guiding base 121 during use, ensuring the smooth movement of the brake wire.

[0049] In the embodiments of the present application, the structural feature of the braking member 122 is mainly that a rack 1222 is provided on the braking member 122. The main function of the rack 1222 is to cooperate with the gear teeth 1252 on the guiding base 121 to realize the movement of the braking member 122 on the guiding base 121. For example, the size of the rack 1222 can be designed as 2mm×5mm (width×length), and the material of the rack 1222 can be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance. Another feasible material is stainless steel.

[0050] The structural feature of the driving mechanism 125 is that it is rotatably connected to the guiding base 121. The driving mechanism 125 is provided with gear teeth 1252. The main function of the gear teeth 1252 is to mesh with the rack 1222 on the braking member 122 to realize the movement of the braking member on the guiding base 121. For example, the size of the gear teeth 1252 can be designed as 2mm×4mm (width×length), and the material of the gear teeth 1252 can be selected from high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance. Another feasible material is stainless steel.

[0051] The connection relationship between the driving mechanism 125 and the braking member 122 is mainly realized by the meshing of the gear teeth 1252 and the rack 1222. This structural design makes the movement of the braking member 122 on the guiding base 121 smoother. For example, the pitch of the gear teeth 1251 is 2mm, and the pitch of the rack 1222 is also 2mm. This meshing relationship makes the movement of the braking member on the guiding base 121 more accurate, improving the braking effect. At the same time, the cooperation between the gear teeth 1252 and the rack 122 can also achieve more precise positioning by adjusting the size of the land. The selection of the land size can ensure the good meshing of the gear teeth 1252 and the rack 122, ensuring the smooth movement of the braking member on the guiding base 121.

[0052] The structural feature of the transmission part 1251 is that an installation part for fixing the brake wire is provided at one end of the transmission part. The installation part fixes the brake wire at the end of the transmission part away from the driving part. The installation part can be set in various styles, including but not limited to a hook style, where the brake wire is fixed through the hook, or it can be set as a clamping part, and the brake wire is fixed through clamping, etc. In this embodiment, the installation part is set as an installation screw. The main function of the installation screw is to fix the brake wire and prevent the brake wire from shifting or loosening during use. For example, the diameter of the installation screw is 6 mm, and the diameter of the screw hole is 7 mm. The material of the installation screw can be selected as high-strength steel or aluminum alloy to ensure its sufficient strength and corrosion resistance. Another feasible material is stainless steel. The brake hole on the installation screw is used to fix the brake wire, and the diameter of the brake hole can be designed as 2 mm, and the diameter of the brake wire is 1.5 mm. The material of the brake wire can be selected as high-strength nylon or stainless steel to ensure its sufficient strength and wear resistance.

[0053] The driving part is rotatably connected to the guiding base 121. An installation groove is opened at the installation position of the guiding base 121 and the driving part. The installation groove is set in an arc shape, and the axis coincides with the axis of the gear teeth 1252. When connecting, the driving part can be arranged on one side of the guiding base 121, or the connection part can also be arranged on both sides of the guiding base 121. In one embodiment, the driving part is clamped on both sides of the guiding base 121 for connection, and the connection part is set in the shape of a U-shaped plate. One side of the U-shaped plate and the driving part are both located on the first side of the guiding base 121, and the other side of the U-shaped plate is located on the second side of the guiding base 121. The purpose of such a setting is that the U-shaped plate is not likely to fall off due to excessive rotation when rotating around the rotation axis, improving the structural safety.

[0054] The structural feature of the mounting seat 127 is that it is arranged between the guiding base 121 and the connecting part 112. As an adjustable interface, it makes the angle and position adjustment of the braking structure 12 more flexible. The mounting seat 127 is provided with a mounting hole 1271 for the screw to pass through. The diameter of the mounting hole 1271 is larger than the diameter of the screw to provide an adjustment space. For example, the diameter of the mounting hole is 8 mm. An arc-shaped circular groove is opened on the side of the mounting seat 127 close to the guiding base 121, and an arc-shaped convex block adapted to the arc-shaped circular groove is provided on the side of the guiding base 121 in contact with the mounting seat 127. The material of the mounting seat can be high-strength aluminum alloy or steel, such as 6061-T6 aluminum alloy.

[0055] In the embodiment of the present application, the brake module 12 further includes a module resetting part 128. The resetting part 128 is used to reset the braking part 122 from the braking position to the release position away from the surface of the wheel rim. The resetting part 128 is set as a torsion spring. One end of the torsion spring is clamped on the guiding base 121, and the other end is connected to the transmission part 1251.

[0056] After the vehicle completes braking, the elastic force of the torsion spring will drive the transmission part 1251 to move, causing the transmission part 1251 to return to its initial state.

[0057] The implementation principle of a braking structure in an embodiment of the present application is as follows: The brake seat 11 includes a mounting part 111 and a connecting part 112, and is connected to the vehicle frame 2 through the mounting part 111. The connecting part 112 is provided with a first long slot hole 1121, and at the same time, the brake module 12 can be adjusted in position within a certain range through the first long slot hole 1121. A second long slot hole 1122 is provided at the position where the connecting part 112 is connected to the brake module 12. The brake module 12 can be conveniently adjusted in position through the second long slot hole 1122, and when the brake module 12 is installed through the guiding base 121 and the second long slot hole 1122, the installation direction can be rotated, which is convenient to adjust the braking part 122 of the brake module 12 to the most suitable position, improving the braking effect. At the same time, pulling the brake wire reduces the distance between the transmission part 1251 and the guiding base 121, driving the braking part 122 to contact the surface of the wheel rim, playing a braking role. By reducing the distance between the transmission part 1251 and the guiding base 121, the braking stability can be improved; when not braking, the transmission part 1251 is far away from the guiding base 121, providing space for the rotation of the transmission part 1251.

[0058] As Figure 5 shown, the braking system in an embodiment of the present application can also be a disc brake system. Corresponding to Figures 1-4 the braking system shown, when the braking system is a disc brake system, only the position of the mounting seat on the vehicle frame needs to be adjusted.

[0059] In another embodiment of the present application, as Figure 6 shown, a bicycle is shown. The bicycle includes components such as a braking system 1 / vehicle frame 2 / wheels 3 or brake discs 4 / saddle, etc. Of course, the bicycle can also have some other components, and the specific forms of each component can be as shown in any other existing technologies. For the sake of simplicity of content, the present application will not give redundant descriptions. The braking system of the bicycle is as shown in the previous Figures 1-4 shown, and the present application will not repeat it here.

[0060] Those skilled in the art can know that the braking system in this solution can be used not only in the Figure 6 bicycle mentioned above, but also in the braking of any vehicle. The present application has no restrictions on this.

[0061] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
