Description

Technical Field

[0001] This invention belongs to the field of road bicycle technology, specifically, it relates to an improvement in the structure of a bicycle operating device. Background Technology

[0002] Existing bicycle operating devices mainly include a handlebar assembly and a main housing part connected to the handlebar assembly for mounting the handlebar assembly to the bicycle handlebar. Since the handlebar assembly and the main housing part are relatively small in size, if corresponding functional module structures are to be installed on the handlebar assembly and the main housing, the size will limit the installation of multiple functional modules, and some functional module structures will inevitably be abandoned, resulting in a poor user experience.

[0003] Furthermore, bicycle operating mechanisms typically only have one type of braking structure, which is fixed to the handlebar assembly and main housing. If it needs to be replaced, the entire set of components needs to be replaced, resulting in high costs.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0035] In some embodiments of this application, the first brake main module includes:

[0036] First brake base;

[0037] The first brake piston rod is slidably disposed within the first brake body;

[0038] The first connecting member is hinged to the end of the first brake piston rod and is slidably disposed on the base member;

[0039] The first brake actuating element is assembled and fixed on the operating member, and includes a first end near the first connector and a second end away from the first connector. The first end abuts against the side of the first connector near the first brake base.

[0040] The first brake reset component is assembled on the base component, with one end abutting against the protrusion of the base component and the other end abutting against the side of the first connector away from the first brake base.

[0041] In some embodiments of this application, the following are also included:

[0045] In some embodiments of this application, a main oil reservoir is formed inside the first brake base;

[0046] A buffer component is arranged above the first brake base, and a secondary oil tank is formed between the buffer component and the first brake base, located above the main oil tank, and the secondary oil tank is connected to the main oil tank.

[0047] The cylinder head body is locked above the main cylinder body and the buffer component is pressed and fixed. An air chamber is formed between the cylinder head body and the buffer component, and the air chamber is connected to the external space.

[0048] A sealing assembly is disposed on the first brake piston rod, forming an oil supply area between the piston rod, the sealing assembly, and the first brake base.

[0049] Specifically, when the first brake piston rod slides outward relative to the first brake base, the oil supply area changes from a state connected to the auxiliary oil tank to a state disconnected from the auxiliary oil tank.

[0077] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0078] The present invention provides an embodiment of a bicycle operating device, comprising: a base component 100, specifically, which is mainly connected to the bicycle handlebars via the base component 100;

[0079] In some embodiments of this application, the base component 100 includes a main housing and a side cover connected to one side of the main housing, and a handlebar locking ring is mounted on the main housing.

[0080] The bicycle operating device is operatively connected to the bicycle component, which can be an electric device or an auxiliary device.

[0081] The bicycle control device can be operatively connected to at least one of the electrical device and the auxiliary device via wireless communication.

[0082] Examples of electrical devices include bicycle seatposts, bicycle suspensions, bicycle shifting mechanisms, bicycle electric brake actuators, or bicycle electric gear shifting actuators.

[0083] And an operating component 200, which is pivotally connected to the base component 100 via a pivot spindle 110, has a connecting end 210 connected to the base component 100 and a free end 220 disposed opposite to the connecting end 210;

[0084] Since the function of the pivot spindle 110 is to connect the operating member 200 and the base member 100, the pivot spindle 110 is set at the connecting part 523 at the head end of the operating member 200.

[0085] Specifically, the operating component 200 is a brake handle, which is rotatably connected to the base component 100 and can rotate relative to the base component 100 by a certain angle when subjected to a force.

[0086] A brake module is connected to the operating member 200 to operate the bicycle component in response to the operation of the operating member 200. In this embodiment, the bicycle component refers to the component that cooperates with the brake module to perform braking action on the bicycle.

[0087] It includes a first braking unit 300 and a second braking unit 400 that can realize two different braking methods;

[0088] The first braking unit 300 and the second braking unit 400 are interchangeably mounted on the base member 100 and the operating member 200.

[0089] In this embodiment, the operating device is arranged with two types of braking units, which can be interchangeably installed on the base component 100 and the operating component 200. When using the device, the user can choose to use the first braking unit 300 or the second braking unit 400, thus realizing the interchangeability of the two braking modes and meeting the user's needs for different braking modes.

[0090] In some embodiments of this application, the first braking unit 300 is a hydraulic braking unit.

[0091] The second braking unit 400 is a cable brake unit. The two braking units are modularized so that users can select the corresponding braking unit according to their actual braking needs.

[0092] The speed change operation module 500 is assembled inside the operation component 200, near the free end 220 of the operation component 200;

[0093] The speed control module 500 requires the user to touch it with their finger. To facilitate user operation and control, it is installed near the free end 220 of the operating component 200.

[0094] The gear shifting module 500 is mainly used to control the electric gear shifting components of a bicycle.

[0095] The main control module 600 is located at the bottom of the base component 100 and is connected to the gear shifting operation module 500. When it receives input signals from the gear shifting operation module 500 or other modules, it can output control signals to control the corresponding bicycle accessory actions.

[0096] The main control module 600 is the control part of the entire bicycle operating device, and it plays the main control role.

[0097] By placing the main control module 600 at the bottom of the entire base component 100, the user will not see the main control module 600 when the operating device is installed on the vehicle body and viewed from above. This achieves the hidden setting of the main control module 600 and enhances the overall aesthetics.

[0098] In addition, by placing the main control module 600 at the bottom, in the event of light rain or fog, rainwater will flow down along the top and sides of the base component 100 and will rarely flow into the main control module 600 located at the bottom, thus providing a certain degree of protection for the main control module 600.

[0099] In some embodiments of this application, the speed change operation module 500 can be connected to the main control module 600 to achieve line number transmission.

[0100] A wireless communication module is also arranged on the main control board module so that the main control module 600 can receive external input signals or send control signals to the outside wirelessly.

[0101] Compared with wired communication, wireless communication reduces structural clutter and space occupation caused by wiring harnesses.

[0102] The main control module 600 is mainly used to receive input signals sent by other modules, analyze and process the received signals, and output control signals to the corresponding parts of the bicycle to control the bicycle parts to move.

[0103] For example, the main control module 600 responds to the signal from the speed change operation module 500.

[0104] In some embodiments of this application, the speed change operation module 500 includes:

[0105] The speed control unit is used for input operations;

[0106] And the transmission control board 510, which responds to the input operation of the transmission operation unit and generates a signal to be transmitted to the main control module 600.

[0107] After receiving and analyzing the trigger signal from the gear shifting module 500, the system sends a control signal to the bicycle gear shifting actuator to perform the gear shifting action.

[0108] The power supply module 700 is electrically connected to the main control module and / or the speed control module, and is capable of supplying power to at least the speed operation module 500 and the main control module 600.

[0109] A power supply module is installed on the operating component 200 and / or the base component 100.

[0110] When it is assembled within the operating component 200, it is closer to the pivot spindle 110 than the transmission operating module 500.

[0111] Specifically, the power supply module 700 is positioned closer to the pivot spindle 110 than the gear shifting operation module 500. That is, the position of the power supply module 700 within the operating member 200 is between the pivot spindle 110 and the gear shifting operation module 500. The power supply module 700 is positioned close to the gear shifting operation module 500 to ensure that the power supply module 700 can conveniently supply power to the gear shifting operation module 500.

[0112] Furthermore, placing the power supply module 700 close to the speed control module within the installation space reduces unnecessary energy consumption and the risk of damage caused by the long power cable.

[0113] The entire power supply module 700 is clamped in the middle, making it less susceptible to damage from bumps and falls, thus ensuring the normal operation of the power supply.

[0114] In some embodiments of this application, the power supply module 700 is a battery module.

[0115] In order to ensure stable installation of the battery module, the operating component 200 is provided with a fixing groove; the battery module is placed in the fixing groove.

[0116] The battery module has a battery compartment for installing batteries, the battery compartment including an upper cover 710 and a lower cover 720; the upper cover 710 includes a hinge end 711 and a fixed end 712; the hinge end 711 is hinged to the lower cover 720, and the fixed end 712 is fixedly connected to the lower cover 720 by a fastener 730; the lower cover 720 is located in a fixing groove; the inner wall shape of the fixing groove is adapted to the outer shell shape of the lower cover 720;

[0117] The lower shell can also be fixedly connected to the mounting groove by means of adhesive or screws.

[0118] When the fixing member 730 is a screw, it passes through the upper cover 710 and the lower cover 720 and is fixedly connected to the operating member 200. The operating member 200 can be provided with mounting holes that cooperate with the fixing member 730. When the battery needs to be replaced, the fixing member 730 is first removed from the mounting hole, and then the upper cover 710 is lifted so that the upper cover 710 is rotated and opened relative to the lower cover 720, that is, opened at a certain angle relative to the lower cover 720, thereby exposing the battery that needs to be replaced.

[0119] In this embodiment, the bicycle operating device is provided with multiple modules. Each module is reasonably arranged on the base component 100 and the operating component 200 according to the actual function and working requirements, so as to make the overall structure of the operating device more compact.

[0120] The operating device is equipped with a first braking unit 300 and a second braking unit 400. The two braking units can be interchangeably mounted on the base component 100 and the operating component 200, realizing the interchangeability of the two braking units, realizing multiple braking methods, and meeting the diverse braking needs of users.

[0121] A speed change operation module 500 is set up, which communicates with the main control module 600. The main control module 600 can directly send signals to control the speed change actuator, making speed change operation more convenient.

[0122] In some embodiments of this application, the following are also included:

[0123] The button module 800 is mounted on the outer wall of the base component 100 and is electrically connected to the main control module 600. When viewed from a direction parallel to the pivot axis 110, the main control module 600 is closer to the pivot axis 110 than the button module 800.

[0124] The button module 800 is a custom button module 800, which can be used to implement some extended functions.

[0125] The button module 800 includes multiple buttons. In some embodiments, the buttons include a first button and a second button; both are located on the top of the base component 100. The first button and the second button are customizable buttons, and function keys on the training vehicle can be integrated into the first button or the second button according to user needs, thereby facilitating user adjustment and control.

[0126] During assembly, the button module 800 is positioned near the inner wall of the base component 100 when the operating device is mounted on the handlebars, so that the user can easily press it.

[0127] In some embodiments of this application, the button module 800 includes a button PCBA board, which is connected to the main control module 600 via wires.

[0128] In some embodiments of this application, the base component 100 is provided with a mounting part 120 at its bottom, and the main control module 600 is coated with rubber on its outside and is assembled at the mounting part 120 and fixed to the base component 100 by a locking member.

[0129] The mounting section 120 is a mounting slot. The main control module 600 includes a main control board, which is wrapped with soft rubber to achieve waterproof and dustproof effects. When fixing, the soft rubber is locked to the base component 100 by locking components.

[0130] Locking screws can be used as locking components.

[0131] In some embodiments of this application, the speed change operation module 500 includes:

[0132] A transmission control board 510 and a button component connected to the transmission control board 510, the button component including:

[0133] The paddle assembly 520 and the pressing assembly 530 are provided. The paddle assembly 520 is rotatably connected to the operating member 200. The paddle assembly 520 triggers the gear control board 510 to generate a gear shift signal through the pressing assembly 530.

[0134] The battery module is electrically connected to the transmission control board 510. The paddle assembly 520 includes a paddle panel 521, a hinge portion 522, and a connecting portion 523. The hinge portion 522 rotatably connects the paddle panel 521 to the side wall of the base member 100 via a pin. The paddle panel 521 has a cantilever structure. During use, the paddle panel 521 rotates relative to the base member 100 when flicked with a finger. The connecting portion 523 contacts the pressing assembly 530. There are two hinge portions 522, symmetrically arranged on one side of the paddle panel 521.

[0135] The pressing assembly 530 includes: a button plate fixing frame 531, a key post 532, and a reset component 533. The speed control plate 510 is provided with a DOM plate 534. The reset component 533 is a reset spring. The key post 532 is mounted on the button fixing frame and can move relative to the button fixing frame. The reset spring is sleeved on the key post 532, with one end abutting against the key post 532 and the other end abutting against the DOM plate 534. The key post 532 is in contact with the paddle panel 521.

[0136] Two pins are pre-inserted into the two round holes at the cantilever position of the paddle shifter panel 521. Each pin extends a certain length from both ends. The inner side of the operating component 200 has a groove that matches the pin. The protruding part of the pin on the paddle shifter panel 521 abuts against the groove of the brake lever, and the pin is engaged inside the operating component 200. The button plate mounting bracket 531 has another groove structure that matches the pin. After the button plate mounting bracket 531 is fastened, the other part of the pin is engaged into the groove of the button plate mounting bracket 531. The two ends of the pin are restricted from axial movement by the structure of the button plate mounting bracket 531 and are fastened to the operating component 200 with screws.

[0137] The signal lights are mounted on the transmission control board 510 inside the transmission operation module 500.

[0142] And the first / second brake actuation element connected to the first / second brake main module is mounted on the rotating main shaft and fixed to the operating member 200 by a fixing structure. Part of it is located in the second accommodating space, and part of it extends from the second accommodating space into the first accommodating space near the first / second brake main module.

[0143] When the first / second brake actuating element is activated, it drives the first / second brake main module to activate, which in turn drives the brake components connected to the first / second brake main module to activate and perform the braking operation.

[0144] When performing the braking action, the operating component 200 drives the first / second braking actuation element to rotate a certain angle relative to the base component 100. When the first / second braking actuation element rotates, it drives the first / second braking main module connected to it to move, which in turn drives the braking execution component connected to the first / second braking main module to move to perform braking.

[0145] The brake actuator uses a structure that is already available in the prior art.

[0146] In some embodiments of this application, the power supply module 700 is located below the first / second braking actuation element when viewed from a direction parallel to the pivot axis 110.

[0147] In some embodiments of this application, the base member 100 includes:

[0148] The first base component is installed on the bicycle handlebar and the second base component is connected to the first base component. The operating member 200 extends into the first base component and is rotatably connected to the base component 100. The first accommodating space includes an accommodating cavity 130 arranged in the second base component. The first / second brake main module is detachably assembled in the accommodating cavity 130.

[0149] A side opening is provided on the side of the receiving cavity 130, and a side cover component is provided at the side opening.

[0150] The side opening facilitates the assembly of the first brake main module 320 into the receiving cavity 130. The side cover component is used to lock and fix the first brake main module 320 onto the main housing after it is assembled in place, so as to press and fix the first brake main module 320.

[0151] In some embodiments of this application, the receiving cavity 130 is provided with an installation positioning structure, and the first brake main module 320 and the second brake main module 410 are both provided with positioning and mating structures that can be used to cooperate with the installation positioning structure.

[0152] By setting and installing positioning structures on both the first brake main module 320 and the second brake main module 410, the first brake main module 320 and the second brake main module 410 can be interchangeably assembled.

[0153] In some embodiments of this application, the mounting and positioning structure includes:

[0154] A limiting abutment 131 is formed within the receiving cavity 130 to limit the ends of the first brake main module 320 / second brake main module 410;

[0156] And an axial limiting part 132 that horizontally limits the first brake main module 320 / second brake main module 410;

[0157] The axial limiting part 132 includes a first protrusion and a first recess arranged sequentially along the horizontal axis of the first brake main module 320 / second brake main module 410.

[0158] The positioning and mating structure includes:

[0159] Abutting and mating parts 380 are arranged at the ends of the first brake main module 320 and the second brake main module 410;

[0160] The abutting part 380 is an end abutting surface, which can be used to abut against the end limiting rib.

[0161] And an axial positioning part 390 arranged on the first brake main module 320 and the second brake main module 410;

[0162] The axial positioning part 390 includes:

[0163] The second locking part is used to engage with the first protrusion.

[0164] The second protrusion is used to snap into the first recess.

[0165] The first brake main module 320 and the second brake main module 410 are assembled in the receiving cavity 130. They are limited in the vertical direction by the upper and lower walls of the receiving cavity 130, and in the horizontal direction by the side cover component and the side wall of the receiving cavity 130. The front end is limited by the limiting abutment part 131 and the abutment mating part 380. In the horizontal axis direction, there are also corresponding axial positioning parts 390 and axial limiting parts 132 that cooperate with each other. They are inserted and mated in the vertical horizontal axis direction to reinforce the axial limitation of the first brake main module 320, ensuring its firmness in installation and fixation inside the base body.

[0166] In some embodiments of this application, the first brake main module 320 includes:

[0167] First brake base 321;

[0168] The first brake piston rod 322 is slidably disposed within the first brake base 321;

[0169] The first connecting member 323 is hinged to the end of the first brake piston rod 322 and is slidably disposed on the base member 100;

[0170] The first brake actuation element 310 is mounted and fixed on the operating member 200, and includes a first end near the first connector 323 and a second end away from the first connector 323. The first end abuts against the side of the first connector 323 near the first brake base 321.

[0171] The first brake reset component 330 is assembled on the base component 100, with one end abutting against the protrusion of the base component 100 and the other end abutting against the side of the first connector 323 away from the first brake base 321.

[0172] The first brake base 321 is a hydraulic brake cylinder body, and the first brake piston rod 322 is located inside the first brake base 321 and can extend and retract relative to the first brake base 321.

[0173] The first connecting member 323 is a connecting shaft, which is hinged to the end of the first brake piston rod 322.

[0174] The positioning and fitting structure is arranged on the first brake base 321.

[0175] A sliding guide groove is formed within the main housing to limit and guide the sliding direction of the first connector 323. The sliding guide part is a sliding guide groove, and there are two of them, which are formed on the two side walls of the main housing. The two ends of the first connector 323 pass through the sliding guide groove of the main housing, so that the first connector 323 can only move along the axial direction of the first brake piston rod 322.

[0176] The first braking actuation element 310 is a shift fork component.

[0177] When the operating member 200 at the lower end of the pivot spindle 110 applies a force backward, the top of the shift fork component rotates around the pivot spindle 110 by an arc, and the shift fork component pushes the first connector 323 forward. The first connector 323, constrained by the sliding guide groove, decomposes the backward thrust applied to it by the shift fork component into an axial force along the first brake piston rod 322, pulling the first brake piston rod 322 forward along the axial direction and extending it.

[0178] In some embodiments of this application, to achieve positioning between the first / second braking actuation element and the operating member 200, the following is also provided:

[0179] A fixing structure for fixing the first brake actuating element 310 includes:

[0180] The position adjustment component 910 has one end screwed onto the second end of the first brake actuation element 310, and the other end abuts against the wall of the operating component 200, which is opposite to the second end position.

[0181] The position adjustment component 910 is a position adjustment screw, one end of which is screwed onto the first brake actuation element 310, and the other end abuts against the wall of the operating component 200.

[0182] The elastic tensioner 920 has one end abutting against the stopper on the operating member 200 and the other end abutting against the first end of the first brake actuating element 310, so that the first end sidewall of the first brake actuating element 310 is abutted and fixed against the sidewall of the second receiving cavity 130 opposite to it.

[0183] The blocking component is a blocking protrusion, and the elastic tensioning element 920 is an elastic tensioning torsion spring. A mounting pin is provided on the operating component 200, and the elastic tensioning torsion spring is sleeved on the mounting pin. One end of the spring abuts against the blocking protrusion, and the other end abuts against the first brake actuating element 310 to apply a tensioning force to the operating component 200 and the first brake actuating element 310.

[0184] The elastic tensioner 920 is arranged above the first brake actuating element 310, and the position adjustment member 910 is arranged below the first brake actuating element 310. Through the cooperation of the forces applied by the two components, the first sidewall at the first end of the first brake actuating element 310 and the second sidewall at the second end on the same side both abut against the wall of the operating member 200.

[0185] The second sidewall and the sidewall with the handle adjustment component 910 are arranged facing away from each other.

[0186] When adjusting the handlebar angle, the handlebar adjustment member 910 can be continuously turned so that it extends and retracts relative to the first brake base 321. Since the first brake base 321 is against the second side wall, its position will not change when it is turned for adjustment. Therefore, when the handlebar adjustment member extends and retracts, it will transmit a force to the operating member 200, causing the operating member 200 to rotate relative to the base member 100 and change the included angle between the two to achieve adjustment.

[0187] The first brake reset component 330 is assembled on the base component 100, with one end abutting against the first connector 323 and the other end abutting against the base component 100.

[0188] After the force on the operating member 200 is removed, it can apply a reverse force to the first brake actuating element 310, which in turn drives the operating member 200 to reset.

[0189] In some embodiments of this application, the first brake base 321 includes a main cylinder body and a cylinder head body 360, and a main oil reservoir is formed inside the main cylinder body;

[0190] A buffer component 340 is arranged above the main cylinder block, and a secondary oil tank 350 is formed between the buffer component and the main cylinder block, located above the main oil tank.

[0191] A recessed groove is formed on the main cylinder block, and a buffer component 340 is laid on the top of the main cylinder block to form an auxiliary oil tank 350 with the recessed groove.

[0192] The auxiliary oil tank 350 is connected to the main oil tank;

[0193] During setup, a first connecting hole and a second connecting hole are provided on the top wall of the main cylinder block to connect the main oil tank and the auxiliary oil tank 350.

[0194] One of the connecting holes can be used for oil injection, and the other connecting hole is used for venting air during oil injection.

[0195] The buffer component 340 is made of soft rubber, which is elastic and can deform under pressure. It forms the upper surface of the auxiliary oil tank and mainly absorbs and releases the pressure caused by the change in brake fluid volume due to the change in the temperature of the brake fluid inside the master cylinder through its deformation.

[0196] The buffer member 340 extends toward the recessed portion to form a buffer protrusion. The buffer protrusion facilitates the squeezing of the buffer member 340 to release pressure when there is an upward air pressure force.

[0197] The cylinder head body 360 is locked above the main cylinder body and presses and fixes the buffer component 340. An air chamber 361 is formed between the cylinder head body 360 and the buffer component 340, and the air chamber 361 communicates with the external space.

[0198] Specifically, during the setup, a gas chamber communication hole can be arranged on the cylinder head body 360 to achieve communication between the gas chamber and the external space.

[0199] A sealing assembly is disposed on the first brake piston rod 322.

[0200] In some embodiments of this application, the sealing assembly includes:

[0201] The first sealing component 371 and the second sealing component 372 are arranged sequentially along the axial direction of the first brake piston rod 322, and an extension port is provided on the main cylinder to facilitate the extension of the first brake piston rod 322.

[0202] The first sealing component 371 is closer to the protrusion than the second sealing component 372.

[0203] A high-pressure oil supply zone is formed between the first sealing component 371 and the main cylinder body, and a low-pressure oil storage zone is formed between the first sealing component 371 and the second sealing component 372.

[0204] The first brake piston rod 322 mainly compresses the hydraulic oil in the high-pressure oil supply area to perform braking operations.

[0205] In the initial state, the high-pressure oil supply zone is connected to the auxiliary chamber through the first connecting hole. At this time, the piston rod moves and the pressure is released through the auxiliary oil chamber 350 and the buffer component 340.

[0206] The low-pressure oil storage area can be connected to the auxiliary oil tank 350 through the second connecting hole.

[0207] In this state, oil can be injected through the oil filling hole.

[0208] Specifically, the oil injection hole is located on one side of the cylinder head 360 on the top surface of the main cylinder block, and the oil injection hole is connected to the auxiliary oil tank 350 through a connecting hole.

[0209] During oil filling, the oil enters the auxiliary oil chamber 350 through the oil filling hole, and then enters the high-pressure oil supply area and low-pressure oil storage area connected to the auxiliary oil chamber 350, so that the main cylinder is filled with hydraulic oil.

[0210] To achieve a seal on the oil filling hole, an oil filling hole screw is also provided, which can be screwed onto the oil filling hole to achieve a seal.

[0211] When braking is required, the first brake piston rod 322 extends outward through the extension port. As the first brake piston rod 322 extends outward, it compresses the hydraulic oil in the high-pressure oil supply zone, and the volume of the hydraulic oil changes. When the first brake piston rod 322 moves closer to the extension port than the first connecting hole, the high-pressure oil supply zone changes from being connected to the auxiliary oil chamber 350 to being disconnected. The first brake piston rod 322 moves to squeeze the hydraulic oil in the high-pressure oil supply zone to supply braking oil.

[0212] At this time, the low-temperature oil storage area and the auxiliary oil tank 350 remain connected, forming a constant-pressure oil storage area between them.

[0213] The first brake unit 300 of this utility model integrates the main cylinder body, the first piston rod, the auxiliary oil tank 350 and the main oil tank and the cylinder head body 360 that constitute the hydraulic brake into a unit module structure, which can be used independently. During installation and assembly, the entire module can be installed or disassembled directly, which facilitates installation and disassembly.

[0214] In terms of structural layout, the hydraulic brake unit forms a main oil chamber on the main cylinder body, and an auxiliary oil chamber 350 is formed between the main cylinder body and the buffer component 340 above it. It is locked and fixed by the cylinder head 360 covering it. The first brake piston rod 322 is set in the main oil chamber. The entire brake unit adopts a vertical arrangement, which is compact and occupies little space.

[0215] The auxiliary oil tank 350 can replenish the hydraulic oil in the main oil tank when it is insufficient, ensuring the hydraulic oil capacity in the main oil tank and thus guaranteeing normal braking operation.

[0216] When the volume expands within the entire brake fluid circuit, it is transmitted to the auxiliary oil chamber 350. The upper part of the buffer component 340 is in line with the external air pressure, and the lower part is the upper surface of the auxiliary oil chamber. The pressure is transmitted to the buffer component 340. Since the buffer component 340 is deformable, it deforms and moves towards the air chamber 361 after being subjected to pressure, so that the air chamber 361 between the cylinder head 360 and the buffer component 340 is reduced, and the volume of the auxiliary oil chamber is increased to release the pressure generated in the oil circuit due to the volume change.

[0217] In some embodiments of this application, the second brake main module 410 includes:

[0218] A second brake base is provided with a brake line, and the brake line has a limiting head;

[0219] A wire hole is provided on the second brake actuation element 420, through which the brake wire passes and is limited by a limiting head;

[0220] The second brake reset component is assembled on the base component 100 to reset the second brake actuating element 420. One end of the component abuts against the base component 100, and the other end abuts against the second brake actuating element 420.

[0221] The second brake base is the second brake seat, and the second brake actuating element 420 corresponds to the wire guide bracket.

[0222] The brake cable is mounted on the second brake base. The limiting head at its end is a mushroom head. After the brake cable passes through the cable hole, the limiting head at one end is locked on the cable guide bracket and limited. The other end is led out from the second brake base and passes through a brake cable mounting hole at the front end of the main housing to connect with the cable brake accessory used for cable braking of the bicycle.

[0223] The components for the cable brake can directly adopt the existing structure in the current technology, and will not be elaborated here.

[0224] The second brake base is provided with a positioning and positioning structure that mates with the mounting and positioning structure in the receiving cavity 130, so that it can be interchanged with the first brake base 321.

[0225] When a force is applied to the bottom of the operating component 200, the operating component 200 rotates around the pivot shaft 110 by a certain angle, and the head of the cable bracket pulls the head of the brake cable forward, which drives the cable brake accessory connected to the brake cable to perform cable brake operation on the bicycle.

[0226] The second brake reset component is a cable brake reset torsion spring, which passes through the pivot main shaft 110. Its fixed end 712 abuts against the cable bracket, and its movable end abuts against the stepped surface at the bottom of the main housing. Its function is to assist the operation component 200 in resetting after it loses force.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
