Referring to fig. 2 and 3, the disc brake 51 includes a brake base 511 and a brake body 512, the brake base 511 is fixedly connected to the fork 10, and the brake body 512 is connected to the brake base 511. The bicycle 100 further comprises a first fixing screw 60, and the brake holder 511 is fixedly connected with the fork blade 10 through the first fixing screw 60.

The disc brake 51 further includes a first brake block 513 and a second brake block 514 (see fig. 4), wherein the first brake block 513 and the second brake block 514 are disposed on the brake body 512 at an interval in the first direction, and a clamping gap is formed therebetween. Specifically, the second brake pad 514 is movable relative to the brake body 512 in a first direction toward or away from the first brake pad 513 to adjust the size of the clamping gap. When the clamping gap is small, the first brake pad 513 and the second brake pad 514 can clamp the disc brake disc 52 to brake the bicycle 100. When the clamping gap is large, the first brake pad 513 and the second brake pad 514 can release the disc brake disc 52 and the bicycle 100 will move freely.

In one embodiment, the disc brake 51 further includes a driving column 515 (see fig. 4), and the driving column 515 is movably connected to the brake body 512 and connected to the fastener of the bicycle 100. The user operates the zipper to move the driving post 515 relative to the brake body 512 in a first direction, and the driving post 515 drives the second brake pad 514 relative to the brake body 512 in a direction approaching the first brake pad 513 to reduce the clamping gap and brake the disc brake disc 52. I.e. the second brake pad 514, has a first surface for contacting the disc brake disc 52 and a second surface oppositely disposed in a first direction, and the drive post 515 is capable of contacting the second surface of the second brake pad 514 to drive the second brake pad 514 in a first direction relative to the brake body 512. Specifically, the disc brake 51 further includes a first reset member and a second reset member, when the user releases the zipper, the driving column 515 resets under the action of the first reset member, the second brake pad 514 resets under the action of the second reset member, the clamping gap increases, the disc brake 51 releases the disc brake 52, and the bicycle 100 moves freely.

In one embodiment, drive post 515 is threadably coupled to brake body 512, and when a user manipulates the zipper, the zipper causes drive post 515 to move helically within brake body 512, thereby causing second brake pad 514 to move in a first direction adjacent to first brake pad 513.

In another embodiment, the driving column 515 is slidably sleeved in the brake body 512, and an accommodating cavity for accommodating brake oil and communicating with the driving column 515 is formed in the brake body 512. When the brake handle is operated, the piston moves to transmit the pressure of the brake fluid in the receiving chamber to the driving post 515, and the driving post 515 moves relative to the brake body 512 to move the second brake pad 514 in a first direction adjacent to the first brake pad 513.

In one embodiment, the brake body 512 is movably connected to the brake base 511, and the brake body 512 can drive the first brake pad 513 to move toward the direction close to the disc brake disc 52. Thus, when braking is needed, the driving column 515 drives the second brake pad 514 to move relative to the brake body 512, and the brake body 512 can also drive the first brake pad 513 to move towards the direction close to the disc brake disc 52, so that the first brake pad 513 and the second brake pad 514 can act on the disc brake disc 52 with the same force in opposite directions, so as to achieve the braking function. Compared with the situation that the brake body 512 is fixed relative to the brake seat 511 in the prior art, the deformation of the disc brake disc 52 is reduced, and the service life of the disc brake disc 52 is prolonged.

Referring to fig. 2 and 4, the disc brake 51 further includes an elastic member 516, and the elastic member 516 is disposed between the brake body 512 and the brake base 511. When the brake body 512 drives the first brake pad 513 to move in a direction close to the disc brake disc 52, the elastic element 516 stores elastic force. Meanwhile, the elastic restoring force of the elastic element 516 can cause the brake body 512 to drive the first brake body 512 to move away from the disc brake disc 52 for resetting. Thus, under the action of elastic element 516, the resetting of brake body 512 relative to brake holder 511 is facilitated.

In one embodiment, the disc brake 51 includes two elastic members 516, and in a second direction intersecting the first direction, the two elastic members 516 are respectively disposed between two ends of the brake body 512 and the brake base 511 to ensure uniformity of force and smoothness of movement of the brake body 512 relative to the brake base 511.

Specifically, the first direction is an axial direction of the mounting shaft 20, and the second direction is perpendicular to the first direction. The first direction and the first direction are both parallel to a horizontal plane when the bicycle 100 is placed on the ground. Of course, in other embodiments, the first and second directions are not limited.

In an embodiment, referring to fig. 2 and 4, the disc brake 51 further includes an adjusting screw 517, and the adjusting screw 517 is threadedly connected to one of the brake base 511 and the brake body 512, so as to adjust the position of the brake body 512 relative to the brake base 511 in the first direction. That is, the initial position of the brake body 512 relative to the brake holder 511 can be adjusted by the adjusting screw 517. That is to say, when the bicycle is not braked, the position of the brake body 512 relative to the brake holder 511 can be adjusted through the adjusting screw 517, so as to ensure that a gap is formed between the two brake pads and the disc brake disc 52, and to avoid that the disc brake disc 52 interferes with the bicycle 100 during the free running of the bicycle 100, so as to reduce the running speed of the bicycle 100.

Specifically, the adjusting screw 517 can make the gap between the two brake pads and the disc brake disc 52 equal, so as to ensure that the disc brake disc 52 does not contact with any brake pad during the free running of the bicycle 100.

In order to better understand the technical solution of the present application, the present application is described in detail with two specific embodiments, but the two specific embodiments do not limit the present application, that is, there are other embodiments besides the two specific embodiments, which are included in the protection scope of the present application.

First embodiment:

referring to fig. 2 and 5, an elongated through hole 5121 extending in a first direction is formed through the brake body 512, an accommodating groove 5122 is formed on an inner wall of the through hole 5121, and a first threaded hole 5123 is formed through an inner wall of the through hole 5121 opposite to the accommodating groove 5122. The brake seat 511 comprises a first body 5111 and a penetrating piece 5112 fixedly connected with the first body 5111, the penetrating piece 5112 is penetrated in the penetrating hole 5121, one end of the elastic piece 516 is abutted against the bottom wall of the containing groove 5122, and the other end is abutted against the outer peripheral surface of the penetrating piece 5112; the adjusting screw 517 is inserted into the first threaded hole 5123 and abuts against the outer peripheral surface of the insertion member 5112. Wherein the penetration member 5112 is movable in the first direction within the penetration hole 5121.

In this embodiment, the through-hole 5112 is a screw, the screw is fixedly connected to the first body 5111 by a thread, the head of the screw passes through the brake body 512, and a gasket is disposed between the head of the screw and the brake body 512. The elastic member 516 is a spring. It should be understood that in other embodiments, the through-member 5112 and the elastic member 516 can be disposed in other manners, and are not limited thereto.

The principle is as follows:

referring to fig. 4, when the adjusting screw 517 is rotated, the brake body 512 is moved rightward against the elastic member 516 to adjust the gap between the two brake pads and the disc brake disc 52, so as to ensure that the gap between the two brake pads and the disc brake disc 52 is equal, thereby preventing the brake pads from contacting the disc brake disc 52 and interfering with the operation of the bicycle 100 during the free operation of the bicycle 100.

When the user drives the driving post 515 to the left by the zipper, the second brake pad 514 moves to the left in the first direction against the elastic force of the second restoring member. Referring to fig. 6, when the second brake pad 514 abuts against the disc brake disc 52, since the disc brake disc 52 is not moved, the second brake pad 514 cannot move leftward any more under the restriction of the disc brake disc 52, and the driving rod 515 for driving the second brake pad 514 to move also cannot move leftward. Since the driving column 515 is screwed with the braking body 512, the driving column 515 is not moved, and the driving column 515 is continuously applied with a rotational force for rotating relative to the braking body 512, so that the braking body 512 moves to the right relative to the through-member 5112 through the through-hole 5121 to compress the elastic members 516 at both ends of the braking body 512. The brake body 512 moves to the right to drive the first brake block 513 fixedly connected with the brake body to move to the right until the brake block abuts against the disc brake disc 52 (see fig. 7). Thus, the first brake pad 513 and the second brake pad 514 act on the disc brake disc 52 with opposite and equal forces to achieve the braking function. When the user releases the zipper, the brake body 512 is reset under the action of the elastic element 516, the driving column 515 is reset under the action of the first reset element, and the second brake pad 514 is reset under the action of the second reset element.

Through the setting, when the brake, two brake blocks can stop the 52 face contactings of dish to avoided the dish to stop the deformation of bending of dish 52, improved the dish under the prerequisite of guaranteeing the brake effect and stopped the life of dish 52.

It should be noted that, in some embodiments, the driving column 515 may also be disposed in the brake body 512 in a sleeved manner, and a receiving cavity for receiving brake oil is disposed in the brake body 512, and the receiving cavity is communicated with the driving column 515. When the user operates the brake handle, the piston moves, so that the pressure of the brake oil in the accommodating cavity is transmitted to the driving column 515, the driving column 515 moves relative to the brake body 512, and the second brake pad 514 moves leftwards in the first direction against the elastic force of the second resetting member. When the second brake pad 514 abuts against the disc brake disc 52, since the disc brake disc 52 is not moved, the second brake pad 514 cannot move leftwards any more under the restriction of the disc brake disc 52, and the driving column 515 for driving the second brake pad 514 to move cannot move leftwards. When the driving column 515 is not moved and the brake fluid in the receiving cavity continues to provide pressure, the brake body 512 will move to the right relative to the through-member 5112 through the through-hole 5121 to compress the elastic members 516 at both ends of the brake body 512. The brake body 512 moves to the right to drive the first brake pad 513 fixedly connected with the brake body to move to the right until the brake body abuts against the disc brake disc 52. When the user releases the zipper, the brake body 512 is reset under the action of the elastic element 516, the driving column 515 is reset under the action of the first reset element, and the second brake pad 514 is reset under the action of the second reset element.

Second embodiment:

referring to fig. 8-10, the brake body 512 includes a second body 5124 and a connecting rod 5125, wherein the connecting rod 5125 is disposed between the brake holder 511 and the second body 5124. The brake seat 511 includes a first body 5111 and a mounting seat 5113 connected to the first body 5111, the connecting rod 5125 is provided with a second threaded hole 5126 in the first direction, the adjusting screw 517 is disposed in the second threaded hole 5126 and penetrates out of the through hole 5114 (see fig. 11) of the mounting seat 5113, and the elastic element 516 abuts between the connecting rod 5125 and the mounting seat 5113. The link 5125 can drive the second body 5124 to rotate relative to the brake holder 511 about a first axis intersecting the first direction.

In this embodiment, the mounting seat 5113 is fixedly coupled to the first body 5111 by a second fixing screw 5115. The elastic member 516 is a conical spring. It should be understood that in other embodiments, the mounting seat 5113 is fixed on the brake seat 511 by other methods, and the arrangement of the elastic element 516 is not limited thereto.

Specifically, the link 5125 can rotate relative to the second body 5124 around a second axis that is spaced from and parallel to the first axis, so that the second body 5124 can rotate relative to the link 5125, the contact area between the first brake pad 513 and the disc brake disc 52 is increased, and the braking effect is ensured.

More specifically, the link 5125 and the first body 5111 are connected by the stepped screw 518, and the link 5125 and the second body 5124 are also connected by the stepped screw 518. Shaft sleeves 519 are arranged between the stepped screws 518 and the first body 5111 and the second body 5124, and the stepped screws 518 are rotatably connected with the first body 5111 and the second body 5124 through the shaft sleeves 519.

The principle is as follows:

referring to fig. 11, when the adjusting screw 517 is rotated, the brake body 512 is moved rightward against the elastic member 516 to adjust the gap between the two brake pads and the disc brake disc 52, so as to ensure that the gap between the two brake pads and the disc brake disc 52 is equal, thereby preventing the brake pads from contacting the disc brake disc 52 and interfering with the running of the bicycle 100 during the free running of the bicycle 100.

When the user drives the driving post 515 to the left by the zipper, the second brake pad 514 moves to the left in the first direction against the elastic force of the second restoring member. Referring to fig. 12, when the second brake pad 514 abuts against the disc brake disc 52, since the disc brake disc 52 is not moved, the second brake pad 514 is restricted by the disc brake disc 52 and can not move to the left, and the driving column 515 for driving the second brake pad 514 to move can not move to the left. Since the driving post 515 is threadedly coupled to the second body 5124, the driving post 515 is not moved, and the driving post 515 is continuously applied with a rotational force for rotating relative to the braking body 512, so that the braking body 512 moves to the right relative to the through-hole 5112 through the through-hole 5121 to compress the elastic members 516 at both ends of the braking body 512. The brake body 512 moves to the right to drive the first brake pad 513 fixedly connected to the brake body to move to the right until the brake body abuts against the disc brake disc 52 (see fig. 13). Thus, the first brake pad 513 and the second brake pad 514 act on the disc brake disc 52 with opposite and equal forces to achieve the braking function. When the user releases the zipper, the brake body 512 is reset under the action of the elastic element 516, the driving column 515 is reset under the action of the first reset element, and the second brake pad 514 is reset under the action of the second reset element.

Through the arrangement, when the brake is performed, the two brake blocks can be in surface contact with the disc brake disc 52, so that the bending deformation of the disc brake disc 52 is avoided, and the service life of the disc brake disc 52 is prolonged on the premise of ensuring the brake effect.

It should be noted that, in some embodiments, the driving column 515 may be disposed inside the brake body 512 in a sleeved manner, and an accommodating cavity for accommodating brake oil is disposed inside the second body 5124, and the accommodating cavity is communicated with the driving column 515. When the user operates the brake handle, the piston moves, so that the pressure of the brake oil in the accommodating cavity is transmitted to the driving column 515, the driving column 515 moves relative to the brake body 512, and the second brake pad 514 moves leftwards in the first direction against the elastic force of the second resetting member. When the second brake pad 514 abuts against the disc brake disc 52, since the disc brake disc 52 is not moved, the second brake pad 514 cannot move leftwards any more under the restriction of the disc brake disc 52, and the driving column 515 for driving the second brake pad 514 to move cannot move leftwards. When the driving column 515 is not moved and the brake fluid in the receiving cavity continues to provide pressure, the brake body 512 will move to the right relative to the through-member 5112 through the through-hole 5121 to compress the elastic members 516 at both ends of the brake body 512. The brake body 512 moves to the right to drive the first brake pad 513 fixedly connected with the brake body to move to the right until the brake body abuts against the disc brake disc 52. When the user releases the zipper, the brake body 512 is reset under the action of the elastic element 516, the driving column 515 is reset under the action of the first reset element, and the second brake pad 514 is reset under the action of the second reset element.

Another embodiment of the present invention further provides a disc brake mechanism 50 included in the bicycle 100 and a disc brake 51 included in the disc brake mechanism 50, and since the bicycle 100 has the beneficial effects, the disc brake mechanism 50 and the disc brake 51 have the same beneficial effects, and are not described herein again.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
