Description

Technical Field

[0001] The present application relates to the field of bicycle brakes, and in particular to a hydraulic disc brake device with modulatable power. Background Art

[0002] Bicycles are a convenient means of transportation. According to different models, they are divided into road bikes, mountain bikes, etc. Brakes are one of the key structures for safe bicycle travel. Bicycles use mechanical disc brakes or hydraulic disc brakes, and hydraulic disc brakes are more commonly used in the field of road riding.

[0003] In the related technology, the hydraulic disc brake includes a brake handle, an oil pipe and a brake caliper. The brake handle is installed on the handlebar of the bicycle, and the brake caliper is installed on the frame near the wheel. The oil pipe connects the brake handle and the brake caliper respectively. When braking, the handle of the brake handle is pulled to make the pistons of the brake caliper approach each other through the pressure of the hydraulic oil, so that the brake pads on the brake caliper clamp the brake disc on the wheel, thereby achieving braking.

[0004] Regarding the above-mentioned related technologies, there is a defect that the contact area between the piston and the hydraulic oil in the brake caliper is fixed, and the force transmitted to the piston is also fixed, so the braking force of the brake pad on the brake disc is also fixed, which leads to the defect that the brake cannot adapt to various application scenarios. Summary of the invention

[0005] In order to change the braking force of a hydraulic disc brake when a brake handle is pressed at a fixed angle, the present application provides a hydraulic disc brake device with modulatable power.

[0006] The present application provides a hydraulic disc brake device with adjustable power, which adopts the following technical solution: A hydraulic disc brake device with modulatable power, comprising: Brake handle; An oil pipe, one end of which is connected to the brake handle A brake caliper, comprising a caliper body and a brake piston, wherein the caliper body is provided with a brake oil circuit, an input portion of the brake oil circuit is communicated with the oil pipe, and the brake piston is sealingly and slidably provided in an output portion of the brake oil circuit; The oil contact adjustment component is arranged at the output part of the brake oil circuit and is used to change the contact area between the brake piston and the oil.

[0007] By adopting the above technical solution, the force applied by the brake handle to the hydraulic oil is fixed. According to Pascal's law, the contact area between the brake piston and the oil can be changed by the oil contact adjustment component. Under the same pressure, the pressure applied to the brake piston can be changed, so the pressure of the brake piston on the brake disc can also change, thereby changing the braking force of the hydraulic disc brake when the brake handle is pressed at a fixed angle.

[0008] Preferably, the caliper body is provided with an installation cavity and a supplementary cavity at the output part near the brake oil circuit, the installation cavity and the supplementary cavity are both connected with the brake oil circuit, and the supplementary cavity is in the shape of an elastic storage bag; the oil contact adjustment component includes an oil contact valve core, a regulating valve and a working drive member, the oil contact valve core is arranged in the brake oil circuit, the oil contact valve core is often connected to the side of the brake piston close to the brake oil circuit, the oil contact valve core has a plurality of oil contact channels, the regulating valve is slidably arranged between the brake oil circuit and the installation cavity, the regulating valve is used to block the end of the oil contact channel away from the brake piston, and the working drive member is connected to the regulating valve.

[0009] By adopting the above technical solution, when the braking force needs to be changed, the regulating valve can be moved through the working drive member so that the regulating valve blocks different numbers of oil contact channels, so that different numbers of oil contact channels can be connected to the brake oil circuit, thereby changing the contact area between the brake piston and the oil. In addition, in this process, blocking the oil contact channels will reduce the space of the brake oil circuit. At this time, part of the oil can enter the supplementary chamber to normally accommodate the hydraulic oil. After the space of the brake oil circuit is restored, the supplementary chamber will shrink to allow the hydraulic oil to re-enter the brake oil circuit.

[0010] Preferably, the oil-contact valve core includes a mounting portion and a telescopic tube portion, the mounting portion is fixedly arranged in the brake oil circuit, and the mounting portion is provided with a plurality of oil-contact holes; one end of the telescopic tube portion is fixedly connected to a side of the mounting portion close to the brake piston, and the other end is connected to the brake piston, and the inner side of the telescopic tube portion and the oil-contact hole form the oil-contact channel.

[0011] By adopting the above technical solution, compared with the method in which the oil-contact valve core is made of elastic material as a whole and is always connected with the brake piston, in this design, during the movement of the brake piston, the brake piston can be stably connected to the oil-contact valve core so that the oil is always in the oil-contact channel, thereby maintaining the stability of the braking force in each gear while achieving a change in the braking force.

[0012] Preferably, a connecting magnet and a connecting adsorption plate are provided between the telescopic tube portion and the brake piston, the connecting magnet is provided on a side surface of the brake piston close to the mounting portion, the connecting adsorption plate is connected to an end surface of the telescopic tube portion away from the mounting portion, and the connecting adsorption plate is magnetically connected to the connecting magnet.

[0013] By adopting the above technical solution, the oil contact valve core and the brake piston are detachably connected, so the oil contact valve core with different oil contact channel diameters can be replaced, thereby changing the limit value of the braking force and adapting to more application scenarios.

[0014] Preferably, the working drive member includes a transmission rope and a return spring, one end of the transmission rope is connected to one end of the regulating valve away from the brake oil circuit, and the other end passes through the outside of the installation cavity to be subjected to external tension to allow the regulating valve to leave the brake oil circuit; the return spring is arranged in the installation cavity, the return spring is connected to one end of the regulating valve away from the brake oil circuit, and the return spring is used to apply a force to the regulating valve to enter the brake oil circuit.

[0015] By adopting the above technical solution, the cooperation between the transmission rope and the reset spring can realize the reciprocating motion of the regulating valve, and the power source is outside the caliper body, so it is also easy to install and set up.

[0016] Preferably, the working drive component also includes a winding wheel, a ratchet, a pawl and a wheel locking torsion spring, the winding wheel is rotatably arranged on the frame of the brake handle, the winding wheel is connected to the end of the transmission rope away from the regulating valve; the ratchet is coaxially connected to the winding wheel; one end of the pawl is rotatably arranged on the frame of the brake handle, and the other end is engaged with the ratchet; the wheel locking torsion spring is connected to the pawl, and is used to keep the pawl engaged with the ratchet in a non-deformed state.

[0017] By adopting the above technical solution, if the braking force needs to be reduced, the winding wheel can be rotated at the handle to gradually reel the transmission rope into the winding wheel. After the regulating valve moves to the predetermined position, the movement direction of the winding wheel can be limited by the cooperation between the ratchet and the pawl, so the braking force can be reduced at the handle. If the braking force needs to be increased, the pawl can be rotated to release the reverse restriction of the winding wheel, so that the regulating valve can be moved through the reset spring, and the winding wheel can be reversed at the same time. After the regulating valve moves to the predetermined position, the pawl is released to allow the pawl to engage with the ratchet to form a reverse restriction on the winding wheel, so that the braking force can be increased at the handle.

[0018] Preferably, the brake handle is provided with a handle swing detection component, the brake handle is provided with a unlocking wheel assembly, and the regulating valve is connected to an independent regulating component. After the handle swing detection component detects that the swing speed of the handle exceeds a predetermined value, the unlocking wheel assembly allows the pawl to disengage from the ratchet wheel, and the independent regulating component allows the regulating valve to reciprocate, so that the braking force of the brake piston changes in a wave shape.

[0019] By adopting the above technical solution, it is highly likely that a large braking force is required when the handle is pressed suddenly and quickly. If the brake piston has a small braking force at this time and people are unable to operate the working drive parts, the reverse restriction on the winding wheel is first released by releasing the wheel lock rent, and then the independent adjustment component allows the adjustment valve to move to increase the braking force rapidly. At the same time, the braking force is also in a wave shape, that is, the braking force can change from large to small, and then from small to large, and the two adjacent wave peaks can also be of different heights, so that while meeting the emergency braking requirements, there can also be protection after the emergency braking, which can make riding safer.

[0020] Preferably, the release lock wheel assembly includes a release slide, an engagement spring and a release magnet, the release slide is slidably arranged, and the release slide is rotatably arranged for the pawl; the engagement spring is connected to the release slide, and is used to apply a force to the release slide in the direction close to the ratchet; the release magnet is fixedly arranged, and the release magnet magnetically attracts the release slide, and is used to allow the release slide to gradually move away from the ratchet.

[0021] By adopting the above technical solution, with the help of the cooperation between the release magnet and the engagement spring, the reciprocating linear motion between the release slides can be realized, so the pawl can be engaged with and separated from the ratchet wheel.

[0022] Preferably, the independent adjustment component includes a telescopic cylinder and a driving magnet, the telescopic cylinder is fixedly arranged on the outside of the caliper body, the driving magnet is connected to the piston rod of the telescopic cylinder, and the driving magnet magnetically attracts the regulating valve.

[0023] By adopting the above technical solution, while realizing the reciprocating motion of the regulating valve, the independent regulating component is located outside the caliper body, so it can be installed as an independent module, which is convenient for completing the assembly of the hydraulic disc brake device and facilitating the matching and installation of the components in the device according to different application scenarios.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The force applied by the brake handle to the hydraulic oil is fixed. According to Pascal's law, the contact area between the brake piston and the oil can be changed by the oil contact adjustment component. Under the same pressure, the pressure applied to the brake piston can be changed, so the pressure of the brake piston on the brake disc can also change, thereby changing the braking force of the hydraulic disc brake when the brake handle is pressed at a fixed angle; 2. However, when the handle is pressed quickly, a large braking force is most likely required. If the brake piston has a small braking force at this time and people cannot operate the working drive parts, the reverse restriction on the winding wheel is first released by releasing the wheel lock rent, and then the independent adjustment component allows the regulating valve to move to increase the braking force rapidly. At the same time, the braking force is also in a wave shape, that is, the braking force can change from large to small, and then from small to large, and the two adjacent wave peaks can also be of different heights, so that while meeting the emergency braking requirements, there can also be protection after the emergency braking, which can make riding safer.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The present application embodiment discloses a hydraulic disc brake device with modulatable power. Figure 1 and Figure 2The hydraulic disc brake device includes a brake handle 1, an oil pipe 2, a brake caliper 3 and an oil contact adjustment component 4. The brake handle 1 is usually set on the handlebar of the bicycle; one end of the oil pipe 2 is connected to the brake handle 1; the brake caliper 3 includes a caliper body 31 and a brake piston 32. The caliper body 31 is usually installed on a frame near the wheel. The caliper body 31 is provided with a brake oil circuit 311. The input part of the brake oil circuit 311 is connected to the oil pipe 2, and the brake piston 32 is sealingly slidably arranged in the output part of the brake oil circuit 311; the oil contact adjustment component 4 is arranged at the output part of the brake oil circuit 311 to change the contact area between the brake piston 32 and the oil.

[0031] Reference Figure 1 and Figure 2 Because the force applied by the brake handle 1 to the hydraulic oil is fixed, according to Pascal's law, the contact area between the brake piston 32 and the oil can be changed by the oil contact adjustment component 4. Under the same pressure, the pressure applied to the brake piston 32 can be changed, so the pressure of the brake piston 32 on the brake disc can also change, thereby changing the braking force of the hydraulic disc brake when the handle of the brake handle 1 is pressed at a fixed angle.

[0032] Reference Figure 1 and Figure 2 In order to change the contact area between the brake piston 32 and the oil, the following implementations are correspondingly implemented: first, the caliper body 31 is provided with an installation cavity 312 and a supplementary cavity 313 at the output part close to the brake oil circuit 311, and the installation cavity 312 and the supplementary cavity 313 are both connected to the brake oil circuit 311, wherein the supplementary cavity 313 is in the shape of an elastic storage bag; second, the oil contact adjustment component 4 includes an oil contact valve core 41, a regulating valve 42 and a working drive member, the oil contact valve core 41 is arranged in the brake oil circuit 311, the oil contact valve core 41 is often connected to the side of the brake piston 32 close to the brake oil circuit 311, the oil contact valve core 41 has a plurality of oil contact channels 5, the regulating valve 42 is slidably arranged between the brake oil circuit 311 and the installation cavity 312, and the regulating valve 42 will block the end of the oil contact channel 5 away from the brake piston 32, so that different numbers of oil contact channels 5 are connected to the brake piston 32, and the working drive member is connected to the regulating valve 42.

[0033] Reference Figure 1 and Figure 2The working principle is as follows. When the braking force needs to be changed, the regulating valve 42 can be moved through the working drive member so that the regulating valve 42 blocks different numbers of oil contact channels 5, so that different numbers of oil contact channels 5 can be connected to the brake oil circuit 311, thereby changing the contact area between the brake piston 32 and the oil. In addition, in this process, blocking the oil contact channel 5 will reduce the space of the brake oil circuit 311. At this time, part of the oil can enter the replenishing chamber 313 to normally accommodate the hydraulic oil. After the space of the brake oil circuit 311 is restored, the replenishing chamber 313 will shrink to allow the hydraulic oil to re-enter the brake oil circuit 311.

[0034] Reference Figure 1 and Figure 2 In order to keep the oil contact valve core 41 always connected to the brake piston 32 and maintain the stability of the contact area between the brake piston 32 and the oil, the oil contact valve core 41 includes a mounting portion 411 and a telescopic tube portion 412. The mounting portion 411 is fixedly arranged in the brake oil circuit 311. The mounting portion 411 is provided with a plurality of oil contact holes 51, and the plurality of oil contact holes 51 are distributed in a rectangular array; the telescopic tube portion 412 is in the shape of a bellows, one end of the telescopic tube portion 412 is fixedly connected to a side of the mounting portion 411 close to the brake piston 32, and the other end is connected to the brake piston 32. The inner side of the telescopic tube portion 412 forms an oil contact channel 5 with the oil contact hole 51. During the movement of the brake piston 32, the brake piston 32 can be stably connected to the oil contact valve core 41 so that the oil is always in the oil contact channel 5, thereby maintaining the stability of the braking force in each gear position under the premise of achieving a change in the braking force.

[0035] Reference Figure 1 and Figure 2 In order to facilitate changing the working parameters of the device, that is, to change the limit value of the braking force of the device, the following settings are correspondingly arranged: a connecting magnet 6 and a connecting adsorption sheet 61 are arranged between the telescopic tube portion 412 and the brake piston 32; the connecting magnet 6 is arranged on the side surface of the brake piston 32 close to the mounting portion 411; the connecting adsorption sheet 61 is connected to the end surface of the telescopic tube portion 412 away from the mounting portion 411; the connecting adsorption sheet 61 is magnetically connected to the connecting magnet 6; the oil contact valve core 41 and the brake piston 32 are detachably connected; therefore, the oil contact valve core 41 with different diameters of the oil contact channel 5 can be replaced, thereby changing the limit value of the braking force and adapting to more application scenarios.

[0036] Reference Figure 1 and Figure 2In order to realize the reciprocating motion of the regulating valve 42 through a simple structure, the working driving part includes a transmission rope 43 and a return spring 44. One end of the transmission rope 43 is connected to the end of the regulating valve 42 away from the brake oil circuit 311, and the other end passes through the installation cavity 312 and will be subjected to external tension to make the regulating valve 42 leave the brake oil circuit 311; the return spring 44 is arranged in the installation cavity 312, and the return spring 44 is connected to the end of the regulating valve 42 away from the brake oil circuit 311. The return spring 44 will apply a force to the regulating valve 42 to enter the brake oil circuit 311. The reciprocating motion of the regulating valve 42 can be realized through the cooperation between the transmission rope 43 and the return spring 44, and the power source is outside the caliper body 31, so it is also convenient for installation and setting.

[0037] Reference Figure 2 and Figure 3 In order to adjust the braking force at the handle, the working drive member also includes a winding wheel 45, a ratchet 46, a pawl 47 and a wheel locking torsion spring 48. The winding wheel 45 is rotatably set on the frame of the brake handle 1, and the winding wheel 45 is connected to the end of the transmission rope 43 away from the regulating valve 42 to gradually wind up the transmission rope 43; the ratchet 46 is coaxially connected to the winding wheel 45; one end of the pawl 47 is rotatably set on the frame of the brake handle 1, and the other end is engaged with the ratchet 46. The pawl 47 limits the reverse rotation of the ratchet 46, that is, limits the winding wheel 45 from sending out the transmission rope 43; the wheel locking torsion spring 48 is connected to the pawl 47, and the pawl 47 and the ratchet 46 are kept engaged when there is no deformation.

[0038] Reference Figure 2 and Figure 3 If the braking force needs to be reduced, the winding wheel 45 can be rotated at the handle to gradually reel the transmission rope 43 into the winding wheel 45. After the regulating valve 42 moves to the predetermined position, the movement direction of the winding wheel 45 can be limited by the cooperation between the ratchet 46 and the pawl 47. Therefore, the braking force can be reduced at the handle. If the braking force needs to be increased, the pawl 47 can be rotated to release the reverse restriction of the winding wheel 45, so that the regulating valve 42 can be moved through the reset spring 44, and the winding wheel 45 can be reversed at the same time. After the regulating valve 42 moves to the predetermined position, the pawl 47 is released to allow the pawl 47 to engage with the ratchet 46 to form a reverse restriction on the winding wheel 45. Therefore, the braking force can be increased at the handle.

[0039] Reference Figure 2 and Figure 3If an emergency occurs during riding, people usually quickly press the handle portion of the brake handle 1 to obtain a larger braking force, and at the same time people cannot operate the working drive member. However, if the brake piston 32 is in the gear position with small braking force at this time, a safety accident may easily occur. Therefore, in order to solve this problem, the following settings are provided: a handle swing detection member is provided on the brake handle 1, a wheel unlocking assembly 7 is provided on the brake handle 1, and an independent adjusting assembly 8 is connected to the regulating valve 42. After the handle swing detection member detects that the swing speed of the handle exceeds a predetermined value, the wheel unlocking assembly 7 is released to allow the pawl 47 to disengage the meshing ratchet 46, and the independent adjusting assembly 8 allows the regulating valve 42 to reciprocate, and at the same time, the braking force of the brake piston 32 changes in a wave shape, that is, the braking force can change from large to small, and then from small to large, and the two adjacent wave peaks can also be of different heights, so that while meeting the emergency braking requirements, there can also be protection processing after the emergency braking, thereby making riding safer.

[0040] Reference Figure 3 The lock wheel release assembly 7 includes a release slide 71, an engagement spring 72 and a release magnet 73. The release slide 71 is slidably arranged, and the ratchet 47 is rotatably arranged on the release slide 71; the engagement spring 72 is connected to the release slide 71, and the engagement spring 72 exerts a force on the release slide 71 in the direction close to the ratchet 46; the release magnet 73 is fixedly arranged on the frame of the brake handle 1, and the release magnet 73 magnetically attracts the release slide 71 to gradually move the release slide 71 away from the ratchet 46. With the help of the cooperation between the release magnet 73 and the engagement spring 72, the reciprocating linear motion between the release slide 71 can be realized, so the ratchet 47 can be engaged with and separated from the ratchet 46.

[0041] Reference Figure 2 The independent adjustment component 8 includes a telescopic cylinder 81 and a driving magnet 82. The telescopic cylinder 81 is fixedly arranged on the outside of the caliper body 31. The driving magnet 82 is connected to the piston rod of the telescopic cylinder 81. The driving magnet 82 magnetically attracts the regulating valve 42. While realizing the reciprocating motion of the regulating valve 42, the independent adjustment component 8 is located outside the caliper body 31, so it can be installed as an independent module, which is convenient for completing the assembly of the hydraulic disc brake device and for matching and installing the components in the device according to different application scenarios.

[0042] The implementation principle of a hydraulic disc brake device with modulatable power in an embodiment of the present application is as follows: the force applied by the brake handle 1 to the hydraulic oil is fixed. According to Pascal's law, the contact area between the brake piston 32 and the oil can be changed by the oil contact adjustment component 4. Under the same pressure, the pressure applied to the brake piston 32 can be changed, so the pressure of the brake piston 32 on the brake disc can also change, thereby changing the braking force of the hydraulic disc brake.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
