[0001] This disclosure relates to the field of vehicle technology, and in particular to a connector, an adjusting member, a brake adjusting device, a brake structure, and a vehicle. Background Technology

[0002] A vehicle's braking system uses brake cables to drive the brake mechanism into frictional contact with the wheel, thereby stopping the wheel's rotation. Typically, a brake adjustment device is needed to adjust the tightness of the brake cables and prevent them from loosening, ensuring that the brake cables reliably and accurately drive the braking system.

[0003] Among related technologies, the brake adjustment device is relatively inconvenient to operate. Utility Model Content

[0004] To address the related technical problems, the present disclosure aims to provide a connector, an adjusting member, a brake adjusting device, a brake structure, and a vehicle, so as to facilitate the operation of the brake adjusting device.

[0005] The technical solution of this disclosure embodiment is implemented as follows:

[0006] The first aspect of this disclosure provides a brake adjustment device, including:

[0007] A connector, including a connector base having a locking portion;

[0008] The adjusting member, when the locking part is in the unlocked state, can move relative to the connecting member to adjust the tightness of the brake cable. The direction in which the adjusting member moves to make the adjustment is the first direction. When the locking part is in the locked state, it contacts the adjusting member to restrict the movement of the adjusting member.

[0009] A fastener is disposed on the connector, and an adjusting member is located between the fastener and the locking part. The fastener and the locking part are arranged in a second direction, which is intersected with the first direction. The fastener is used to switch the adjusting member between the locked state and the unlocked state.

[0010] In some embodiments, the connector includes a connecting shaft connected to the connecting seat, and the fastener is sleeved on the connecting shaft.

[0011] In some embodiments, the adjusting member has a guide groove extending along the first direction, and the connecting shaft passes through the guide groove along the second direction.

[0012] In some embodiments, the locking portion is a first engaging portion, and the adjusting member has a second engaging portion on the side facing the locking portion along the second direction. The first engaging portion engages with the second engaging portion to restrict the movement of the adjusting member relative to the connecting member along the first direction.

[0013] In some embodiments, one end of the adjusting member along the first direction is a first end for setting a brake line, and the other end of the adjusting member arranged opposite to the first end is a second end. Along the direction from the first end to the second end, the thickness of the adjusting member gradually increases along the second direction, and the locking part fits against the adjusting member along the second direction in the locked state.

[0014] In some embodiments, the surface of the adjusting member facing the fastener along the second direction is perpendicular to the second direction, the surface of the adjusting member away from the fastener along the second direction is arranged intersecting the second direction, and the surface of the connecting seat facing the fastener along the second direction is arranged intersecting the second direction.

[0015] In some embodiments, the angle between the surface of the adjusting member away from the fastener along the second direction and the surface of the adjusting member towards the fastener along the second direction is a preset angle, which is 1° to 6°.

[0016] In some embodiments, the surface of the adjusting member facing the fastener along the second direction is perpendicular to the second direction, the surface of the adjusting member away from the fastener along the second direction is perpendicular to the second direction, and the surface of the connecting seat facing the fastener along the second direction is perpendicular to the second direction.

[0017] In some embodiments, the connecting seat has limiting portions on both sides along a third direction, the limiting portions protruding from the locking portion toward the adjusting member along the second direction, the adjusting member abutting against the limiting portions on both sides along the third direction, and the third direction being arranged intersecting the first direction and the second direction respectively.

[0018] In some embodiments, the connector is threadedly connected to the fastener, the fastener being used to prevent loosening between the fastener and the connector.

[0019] In some embodiments, the fastener includes a first nut fitted onto the connector and a second nut threadedly connected to the first nut. The first nut has a first thread connecting to the second nut, and the second nut has a second thread connecting to the first nut. The first thread and the second thread are eccentrically arranged. Alternatively, the fastener includes a third nut fitted onto the connector and a first washer and a second washer located between the third nut and the adjusting member. The first washer and the second washer are arranged along a second direction. The first washer has a first surface on the side facing the second washer, and the first washer has a second surface on the side facing the second washer that contacts the first surface. Both the first surface and the second surface are arranged intersecting the second direction. The first washer has at least two first surfaces along its circumference, and the second washer has at least two second surfaces along its circumference.

[0020] In some embodiments, the material of the connector is the same material used to manufacture bolts with a performance grade of 8.8; and / or, the material of the adjusting member is the same material used to manufacture bolts with a performance grade of 8.8.

[0021] A second aspect of this disclosure provides a braking structure, including:

[0022] Brake body;

[0023] The brake adjustment device described above is disposed on the brake body;

[0024] Brake cable, installed on the brake adjustment device.

[0025] In some embodiments, the brake body includes a swing arm, a reset member, and a brake. One end of the swing arm is rotatably connected to the brake, and the other end of the swing arm is rotatably connected to the connector. The brake cable can drive the brake adjustment device to rotate the swing arm to trigger the brake. One end of the reset member abuts against the brake, and the other end of the reset member abuts against the swing arm.

[0026] In some embodiments, when projected along the second direction, the projection area of ​​the end of the reset member that abuts against the swing arm is located outside the projection area of ​​the swing arm, and the end of the reset member that abuts against the swing arm is located on the side of the swing arm facing the brake line along the first direction.

[0027] In some embodiments, the brake cable includes an interconnected main line and a mounting portion protruding radially along the main line. The adjusting member has an interconnected mounting groove and a cable guide groove. The mounting portion is located within the mounting groove. The groove wall of the mounting groove facing the main line in the first direction is a first wall. The first wall abuts against the mounting portion to restrict the movement of the brake cable relative to the adjusting member in the first direction. The cable guide groove is located within the first wall and is used to avoid the main line.

[0028] In some embodiments, the brake adjustment device includes a stop member connected to the first wall. The stop member has a notch communicating with the cable tray, the notch being used to avoid the main line. The main line is partially located between the stop member and the first wall along the second direction. When the adjustment member is in the locked state, its projection along the second direction is such that the projection area of ​​the main line is partially located within the projection area of ​​the stop member, so that the stop member can restrict the main line from leaving the cable tray along the second direction.

[0029] In some embodiments, the first wall is arc-shaped, and the surface of the mounting portion that abuts against the first wall is arc-shaped.

[0030] A third aspect of this disclosure provides a vehicle, including:

[0035] This disclosure provides a brake adjustment device in which an adjusting member can move relative to a connecting member to adjust the tightness of the brake cable. The direction in which the adjusting member moves to make the adjustment is a first direction. The adjusting member is located between a fastener and a locking part. The arrangement direction of the fastener and the locking part is a second direction. The fastener and the locking part press the adjusting member together along the second direction to lock the adjusting member. The locking distance of the fastener is not limited by the distance the adjusting member moves along the first direction. During maintenance when the brake cable travel is large, the locking distance of the fastener can still be small, which facilitates quick locking after adjusting the brake cable.

[0050] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this disclosure.

[0051] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this disclosure will not be described separately.

[0052] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions in normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions in normal use.

[0053] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0054] In related technologies, one end of the brake cable is fixedly connected to a threaded post. The threaded post passes through the positioning part of the pin on the rocker arm and is threadedly connected to an adjusting nut. The adjusting nut is used to restrict the axial movement of the threaded post on the positioning part, thereby locking the position of the threaded post relative to the positioning part. When the threaded post is locked, the adjusting nut and the positioning part abut against each other along the axial direction of the threaded post to keep the brake cable taut. When it is necessary to adjust the tension of the brake cable, first use a tool to fix the threaded post to prevent it from twisting, then tighten or loosen the adjusting nut to allow the threaded post to move axially on the positioning part. As a structure for adjusting the tension of the brake cable, the direction of movement of the threaded post relative to the positioning part and the direction of movement of the adjusting nut to lock the threaded post and the positioning part are basically along the axial direction of the threaded post. The two directions are basically consistent. After the threaded post moves to the adjusted position relative to the positioning part, the adjusting nut needs to be rotated to abut against the positioning part to lock the position of the threaded post relative to the positioning part. Therefore, the adjusting nut moves from the position before adjustment to the position after adjustment to lock the position of the threaded post. The locking distance between the threaded post and the positioning part is roughly equivalent to the distance the threaded post moves relative to the positioning part. The distance the adjusting nut moves from the pre-adjustment position to the post-adjustment position to lock the threaded post and the positioning part is limited by the distance the threaded post moves relative to the positioning part. Due to the need to adjust the tightness of the brake cable, the threaded post is relatively long. During the process of installing the threaded post to the preset position of the positioning part and locking it with the adjusting nut, or when the brake cable is relatively loose and the adjustment stroke is long, the distance the adjusting nut moves along the axial direction of the threaded post during the process of moving the adjusting nut to abut against the positioning part to lock the threaded post and the positioning part is also relatively long, which is inconvenient for installation or maintenance operations.

[0055] This disclosure provides a braking structure; please refer to [link / reference]. Figures 1-4 The braking structure includes a brake body 30, a brake adjustment device 10, and a brake cable 20; the brake adjustment device 10 is disposed on the brake body 30; and the brake cable 20 is installed on the brake adjustment device 10.

[0056] In some embodiments, please refer to Figures 1-5 , Figure 8, Figure 11 and Figure 12 The brake body 30 includes a swing arm 302, and the brake adjustment device 10 is disposed on the swing arm 302.

[0057] This disclosure provides a vehicle, which includes a vehicle body and a braking structure; the braking structure is installed on the vehicle body, and the brake line 20 is connected to the vehicle body.

[0058] One end of the brake line 20 is set on the brake adjustment device 10, and the other end of the brake line 20 is connected to the vehicle body.

[0059] This disclosure provides a brake adjustment device 10. Please refer to [link / reference]. Figures 1-4 and Figure 8 The brake adjustment device 10 includes a connector 3, an adjustment member 2, and a fastener 1. The connector 3 includes a connecting seat 33, which has a locking part 31. When the locking part 31 is in the unlocked state, the adjustment member 2 can move relative to the connector 3 to adjust the tightness of the brake cable 20. The direction in which the adjustment member 2 moves to make the adjustment is a first direction R1. When the locking part 31 is in the locked state, it contacts the adjustment member 2 to restrict the movement of the adjustment member 2. The fastener 1 is disposed on the connector 3, and the adjustment member 2 is located between the fastener 1 and the locking part 31. The arrangement direction of the fastener 1 and the locking part 31 is a second direction R2. The second direction R2 is intersected with the first direction R1. The fastener 1 is used to switch the adjustment member 2 between the locked state and the unlocked state.

[0060] It should be noted that when the adjusting member 2 is in the unlocked state, the adjusting member 2 moves along the first direction R1 to adjust the tightness of the brake cable 20. When the adjusting member 2 is in the locked state, the adjusting member 2 can basically not move along the first direction R1.

[0061] For example, when the adjusting member 2 is in the unlocked state, the adjusting member 2 can move along the second direction R2. The effect of the adjusting member 2 moving along the second direction R2 on the tightness of the brake cable 20 is relatively small.

[0062] For example, the first direction R1 is perpendicular to the second direction R2.

[0063] For example, the fastener 1 can move along the second direction R2 to switch the adjusting member 2 between a locked state and an unlocked state.

[0064] For example, when the adjusting member 2 is in the locked state, the locking part 31 clamps the adjusting member 2 with the fastener 1, and the static friction between the adjusting member 2 and the locking part 31 and the fastener 1 restricts the adjusting member 2 from moving along the first direction R1; when the fastener 1 moves along the second direction R2 to make the adjusting member 2 in the unlocked state, the fastener 1 no longer applies pressure to the adjusting member 2, the friction between the adjusting member 2 and the locking part 31 and the fastener 1 is small, and the adjusting member 2 can overcome the friction to move along the first direction R1.

[0065] In this embodiment, the adjusting member 2 can move relative to the connecting member 3 to adjust the tightness of the brake cable 20. The direction in which the adjusting member 2 moves to make adjustment is the first direction R1. The adjusting member 2 is located between the fastener 1 and the locking part 31. The arrangement direction of the fastener 1 and the locking part 31 is the second direction R2. The fastener 1 and the locking part 31 press the adjusting member 2 along the second direction R2 to make the adjusting member 2 locked. The locking distance of the fastener 1 is not limited by the distance the adjusting member 2 moves along the first direction R1. During maintenance when the brake cable 20 has a large stroke, the locking distance of the fastener 1 can still be small, which is convenient for quick locking after adjusting the brake cable 20.

[0066] In some embodiments, please refer to Figures 1-4 and Figure 8 The connecting seat 33 has a stop flange 331 at one end away from the adjusting member 2 along the second direction R2. The stop flange 331 is used to limit the relative position of the connecting seat 33 and the brake body 30 along the second direction R2.

[0067] For example, the stop flange 331 is used to limit the relative position of the connecting seat 33 and the rocker arm 302 along the second direction R2.

[0068] For example, the swing arm 302 has a mounting hole, the connecting seat 33 is partially inserted through the mounting hole, the swing arm 302 is located between the stop flange 331 and the adjusting member 2 along the second direction R2, and the stop flange 331 abuts against the swing arm 302 on the side facing the adjusting member 2 along the second direction R2.

[0069] For example, the adjusting member 2 can restrict the connecting seat 33 from moving toward the swing arm 302 along the second direction R2.

[0070] For example, the diameter of the stop flange 331 is larger than the diameter of the mounting hole.

[0071] In this embodiment, the connecting seat 33 has a stop flange 331 at one end away from the adjusting member 2 along the second direction R2. The stop flange 331 is used to limit the relative position of the connecting seat 33 and the swing arm 302 along the second direction R2. The stop flange 331 can limit the connecting seat 33 from disengaging from the brake body 30 on one side along the second direction R2, which is beneficial to improving the installation stability of the brake adjusting device 10.

[0072] It is understood that the end of the connecting seat 33 away from the adjusting member 2 along the second direction R2 is not limited to having a stop flange 331. Exemplarily, the adjusting member 2 has a stop portion for limiting the relative position of the adjusting member 2 with the rocker arm 302 along the second direction R2.

[0073] In some embodiments, please refer to Figures 1-4 and Figure 8The connector 3 includes a connecting shaft 32 connected to the connecting seat 33, and a fastener 1 is sleeved on the connecting shaft 32.

[0074] For example, the connecting shaft 32 protrudes from the connecting seat 33 along the second direction R2 toward the fastener 1.

[0075] For example, the locking part 31 is disposed around the connecting shaft 32.

[0076] In this embodiment, the fastener 1 is sleeved on the connecting shaft 32. The fastener 1 and the connecting shaft 32 cooperate to lock or unlock the adjusting member 2, reducing the restriction on the fastener 1 caused by the locking part 31 and the adjusting member 2, and facilitating the cooperation between the connecting member 3 and the fastener 1.

[0077] It is understood that the connector 3 is not limited to including the connecting shaft 32. Exemplarily, the connector 33 is connected to the fastener 1 by bolts.

[0078] In some embodiments, please refer to Figure 2 , Figure 6 , Figure 10 and Figure 11 The adjusting member 2 has a guide groove 21 extending along the first direction R1, and the connecting shaft 32 passes through the guide groove 21 along the second direction R2.

[0079] For example, please refer to Figure 11 The connecting shaft 32 has a guide portion 321 at one end facing the connecting seat 33 along the second direction R2, and the guide portion 321 is located in the guide groove.

[0080] For example, please refer to Figure 11 Projecting along the second direction R2, the projection area of ​​the guide part 321 is rectangular.

[0081] For example, the groove walls on both sides of the guide groove 21 are in contact with the locking part 31.

[0082] In this embodiment of the present disclosure, the adjusting member 2 has a guide groove 21 extending along the first direction R1, and the connecting shaft 32 passes through the guide groove 21 along the second direction R2. The guide groove 21 guides the movement of the adjusting member 2 along the first direction R1, which can better control the movement direction of the adjusting member 2 and reduce the offset of the adjusting member 2.

[0083] It is understood that the adjusting member 2 may not have a guide groove 21 extending along the first direction R1. Exemplarily, the adjusting member 2 is located on one side of the connecting shaft 32 along the radial direction of the connecting shaft 32.

[0084] In some embodiments, please refer to Figures 2-9The locking part 31 is a first engaging part 34. The adjusting member 2 has a second engaging part 22 on the side facing the locking part 31 along the second direction R2. The first engaging part 34 engages with the second engaging part 22 to restrict the movement of the adjusting member 2 relative to the connecting member 3 along the first direction R1.

[0085] For example, please refer to Figure 9 The first engaging part 34 has at least two engaging teeth protruding toward the adjusting member 2 along the second direction R2. The angle between the tooth surface of the engaging tooth along the first direction R1 toward the brake line 20 and the second direction R2 is the first angle, and the angle between the tooth surface of the engaging tooth along the first direction R1 away from the brake line 20 and the second direction R2 is the second angle. The first angle is greater than the second angle.

[0086] The first included angle is shown in the figure with dimension m.

[0087] The second included angle is shown in the dimension n in the figure.

[0088] For example, the meshing teeth of the first meshing part 34 are involute teeth.

[0089] For example, the meshing teeth of the second meshing part 22 are involute teeth.

[0090] In this embodiment, the locking part 31 is a first engaging part 34, and the adjusting member 2 has a second engaging part 22 on the side facing the locking part 31 along the second direction R2. The first engaging part 34 and the second engaging part 22 engage to restrict the movement of the adjusting member 2 relative to the connecting member 3 along the first direction R1. When the adjusting member 2 is in the locked state, the engagement of the first engaging part 34 and the second engaging part 22 can reduce the sliding of the adjusting member 2 towards the brake line 20 along the first direction R1. The first engaging part 34 and the second engaging part 22 can reduce the sliding of the adjusting member 2 away from the brake line 20 along the first direction R1, reduce the positional movement of the adjusting member 2 in the locked state, make the position of the adjusting member 2 and the brake line 20 more stable and reliable, reduce the possibility of the brake adjusting device 10 loosening or moving, and reduce the possibility of the brake line 20 loosening. The first engagement part 34 and the second engagement part 22 engage, which allows the operator to judge the moving distance of the adjusting member 2 along the first direction R1 based on the first engagement part 34 and the second engagement part 22, and facilitates the adjustment of the tightness of the brake cable 20.

[0091] It is understood that the locking part 31 is not limited to the first engaging part 34, and the adjusting member 2 is not limited to having the second engaging part 22. Exemplarily, the locking part 31 is a limiting post protruding toward the adjusting member 2 along the second direction R2, and the adjusting member 2 has limiting holes arranged along the first direction R1. The limiting post can be located in the limiting holes, and the limiting holes can restrict the movement of the limiting post relative to the connecting member 3 along the first direction R1.

[0092] For example, the locking part 31 has a knurled surface.

[0093] For example, the surface of the adjusting member 2 facing the locking part 31 along the second direction R2 is knurled.

[0094] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 One end of the adjusting member 2 along the first direction R1 is the first end 23 for setting the brake line 20, and the other end of the adjusting member 2 arranged opposite to the first end 23 is the second end 24. Along the direction from the first end 23 to the second end 24, the thickness of the adjusting member 2 gradually increases along the second direction R2. The locking part 31 fits against the adjusting member 2 along the second direction R2 in the locked state.

[0095] For example, please refer to Figure 7 The second engagement portion 22 has at least two engagement teeth protruding toward the locking portion 31 along the second direction R2. The surface of the adjusting member 2 toward the fastener 1 along the second direction R2 is a preset surface 27. The thickness of the adjusting member 2 along the second direction R2 is the minimum distance from the preset surface 27 along the second direction R2 to the tip of the engagement tooth.

[0096] The thickness of the adjusting member 2 along the second direction R2 is shown in the figure with dimensions h1, h2 and h3.

[0097] For example, the thickness of the connector 33 gradually changes along the second direction from the first end 23 to the second end 24.

[0098] For example, please refer to Figure 7 In any two adjacent meshing teeth on the second meshing part 22, the meshing tooth that is directed toward the brake line 20 along the first direction R1 is the first meshing tooth 221, and the other meshing tooth is the second meshing tooth 222. The thickness of the adjusting member 2 gradually increases along the second direction R2, which means that the minimum distance from the preset surface 27 along the second direction R2 to the tip of the first meshing tooth 221 is less than the minimum distance from the preset surface 27 along the second direction R2 to the tip of the second meshing tooth 222.

[0099] In this embodiment, the thickness of the adjusting member 2 gradually increases along the second direction R2 in the direction from the first end 23 to the second end 24. The locking part 31 fits against the adjusting member 2 along the second direction R2 in the locked state. When the distance between the fastener 1 and the locking part 31 remains unchanged, the gradual increase in the thickness of the adjusting member 2 along the second direction R2 in the direction from the first end 23 to the second end 24 increases the difficulty of the adjusting member 2 moving towards the brake line 20 in the first direction R1. This is beneficial for the fastener 1 to lock the adjusting member 2, reduces the positional movement of the adjusting member 2 in the locked state, and makes the positions of the adjusting member 2 and the brake line 20 more stable and reliable. This reduces the possibility of the brake adjusting device 10 loosening or moving, and reduces the possibility of the brake line 20 loosening.

[0100] It is understood that the thickness of the adjusting member 2 along the second direction R2 in the direction from the first end 23 to the second end 24 is not limited to gradually increasing. For example, the thickness of the adjusting member 2 along the second direction R2 in the direction from the first end 23 to the second end 24 remains unchanged.

[0101] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2. The surface of the adjusting member 2 away from the fastener 1 along the second direction R2 is intersected with the second direction R2. The surface of the connecting seat 33 facing the fastener 1 along the second direction R2 is intersected with the second direction R2.

[0102] For example, the surface of the adjusting member 2 facing away from the fastener 1 along the second direction R2 is a plane.

[0103] For example, the surface of the connector 33 facing the fastener 1 along the second direction R2 is a plane.

[0104] For example, the surface of the adjusting member 2 facing away from the fastener 1 along the second direction R2 is parallel to the surface of the connecting seat 33 facing the fastener 1 along the second direction R2.

[0105] For example, please refer to Figure 7 When the second engaging part 22 has at least two engaging teeth protruding towards the locking part 31 along the second direction R2, one of which is the third engaging tooth and the other is the fourth engaging tooth, the plane in contact with the third engaging tooth and the fourth engaging tooth is the reference surface 28. The second engaging part 22 is located on the side of the reference surface 28 facing the fastener 1 along the second direction R2. The reference surface 28 is the surface of the adjusting member 2 away from the fastener 1 along the second direction R2. The reference surface 28 is arranged intersecting the second direction R2.

[0106] For example, please refer to Figure 3 When the locking part 31 is the first engaging part 34, the first engaging part 34 has at least two engaging teeth protruding towards the adjusting member 2 along the second direction R2, one of which is the fifth engaging tooth and the other is the sixth engaging tooth. The plane that contacts the fifth and sixth engaging teeth is the connecting surface. The first engaging part 34 is located on the side of the connecting surface away from the fastener 1 along the second direction R2. The connecting surface is the surface of the connecting seat 33 facing the fastener 1 along the second direction R2. The connecting surface is arranged intersecting the second direction R2.

[0107] For example, when the adjusting member 2 moves on the locking part 31, the direction of movement of the adjusting member 2 is parallel to the reference surface 28.

[0108] In this embodiment, the surface of the adjusting member 2 facing away from the fastener 1 along the second direction R2 is arranged intersecting the second direction R2, and the surface of the connecting seat 33 facing the fastener 1 along the second direction R2 is arranged intersecting the second direction R2. The surface of the adjusting member 2 facing away from the fastener 1 along the second direction R2 is inclined towards the side facing away from the fastener 1 along the second direction R2, which helps to reduce the sliding of the adjusting member 2 along the first direction R1 in the locked state, making the position of the adjusting member 2 and the brake line 20 more stable and reliable, reducing the possibility of the brake adjusting device 10 loosening or moving, and reducing the possibility of the brake line 20 loosening.

[0109] It is understood that the surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is not limited to being perpendicular to the second direction R2. Exemplarily, the minimum angle between the surface of the adjusting member 2 facing the fastener 1 along the second direction R2 and the second direction R2 is greater than 0° and less than 90°.

[0110] In some embodiments, when the locking part 31 is a first engaging part 34, the first engaging part 34 has at least two engaging teeth protruding towards the adjusting member 2 along the second direction R2. The angle between the tooth surface of the engaging tooth along the first direction R1 towards the brake line 20 and the second direction R2 is a first angle, and the angle between the tooth surface of the engaging tooth of the first engaging part 34 along the first direction R1 away from the brake line 20 and the second direction R2 is a second angle. The first angle is greater than the second angle. One of the engaging teeth of the first engaging part 34 is a fifth engaging tooth, and the other engaging tooth of the first engaging part 34 is a sixth engaging tooth. The plane in contact with the fifth and sixth engaging teeth is a connecting surface. The first engaging part 34 is located along the second direction R2 on the side of the connecting surface away from the fastener 1. The connecting surface is the connecting seat 33 along the second direction R2 towards the adjusting member 2. The connecting surface on the fastener 1 side is arranged intersecting the second direction R2; when the second engaging part 22 has at least two engaging teeth protruding towards the locking part 31 along the second direction R2, one of the engaging teeth of the second engaging part 22 is the third engaging tooth, and the other engaging tooth of the second engaging part 22 is the fourth engaging tooth, the plane in contact with the third engaging tooth and the fourth engaging tooth is the reference surface 28, the second engaging part 22 is located on the side of the reference surface 28 facing the fastener 1 along the second direction R2, the reference surface 28 is the surface of the adjusting member 2 away from the fastener 1 along the second direction R2, and the reference surface 28 is arranged intersecting the second direction R2; the engaging teeth of the first engaging part 34 engage with the engaging teeth of the second engaging part 22, and the surface of the adjusting member 2 on the side of the fastener 1 along the second direction R2 is perpendicular to the second direction R2.

[0111] For example, reference surface 28 is parallel to the connection surface.

[0112] In this embodiment, the meshing teeth of the first meshing part 34 and the meshing teeth of the second meshing part 22 mesh together. The connecting surface is arranged intersecting with the second direction R2, and the reference surface 28 is arranged intersecting with the second direction R2. The surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2, which increases the difficulty of moving the adjusting member 2 in the locked state. This helps to reduce the possibility of the adjusting member 2 moving in the locked state, making the position of the adjusting member 2 and the brake line 20 more stable and reliable, reducing the possibility of the brake adjusting device 10 loosening or moving in position, and reducing the possibility of the brake line 20 loosening.

[0113] In some embodiments, please refer to Figure 7 The angle between the surface of the adjusting member 2 away from the fastener 1 along the second direction R2 and the surface of the adjusting member 2 towards the fastener 1 along the second direction R2 is a preset angle, which is 1° to 6°.

[0114] For example, the adjusting member 2 includes an adjusting body and a connecting part, the connecting part being used to set the brake line 20, and the adjusting body being used to contact the locking part 31 to restrict the movement of the adjusting member 2.

[0115] For example, the second engagement portion 22 is disposed on the adjustment body.

[0116] It should be noted that the surface of the adjusting member 2 facing away from the fastener 1 along the second direction R2 refers to the surface of the adjusting body facing away from the fastener 1 along the second direction R2, and the surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is the surface of the adjusting body facing away from the fastener 1 along the second direction R2.

[0117] For example, the preset angle is the angle between the preset surface 27 and the reference surface 28.

[0118] The preset included angle is shown in the dimension L in the figure.

[0119] For example, the preset included angle is 1°, 2°, 3°, 4°, 5° or 6°.

[0120] In this embodiment, the angle between the surface of the adjusting member 2 away from the fastener 1 along the second direction R2 and the surface of the adjusting member 2 towards the fastener 1 along the second direction R2 is a preset angle, which is 1° to 6°. The preset angle is within a suitable range, and the thickness difference of the adjusting member 2 along the second direction R2 is within a suitable range. In order to reduce the movement of the adjusting member 2 along the first direction R1 in the locked state, the space required by the adjusting member 2 in the second direction R2 is within a suitable range.

[0121] It is understood that the preset included angle is not limited to 1° to 6°. For example, the preset included angle is 7°.

[0122] In some embodiments, please refer to Figures 8-10 The surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2, and the surface of the adjusting member 2 away from the fastener 1 along the second direction R2 is perpendicular to the second direction R2. The surface of the connecting seat 33 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2.

[0123] For example, the first direction R1 is perpendicular to the second direction R2.

[0124] For example, the surface of the connecting seat 33 facing the adjusting member 2 along the second direction R2 is a first plane, and the first plane is perpendicular to the second direction R2.

[0125] For example, reference plane 28 is perpendicular to the second direction R2.

[0126] For example, the surface of the connector 33 facing the fastener 1 along the second direction R2 is a second plane, and the second plane is perpendicular to the second direction R2.

[0127] For example, the connecting surface is perpendicular to the second direction R2.

[0128] In this embodiment, the surface of the adjusting member 2 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2, the surface of the adjusting member 2 facing the locking part 31 along the second direction R2 is perpendicular to the second direction R2, and the surface of the connecting seat 33 facing the fastener 1 along the second direction R2 is perpendicular to the second direction R2. The thickness of the adjusting member 2 along the second direction R2 remains approximately constant, and the thickness of the connecting seat 33 along the second direction R2 can also remain approximately constant, which facilitates the processing of the adjusting member 2 and the connecting seat 33.

[0129] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 8 and Figure 11 The connecting seat has limiting portions 35 on both sides along the third direction R3. The limiting portions 35 protrude from the locking portion 31 towards the adjusting member 2 along the second direction R2. The adjusting member 2 abuts against the limiting portions 35 on both sides along the third direction R3. The third direction R3 is arranged intersecting the first direction R1 and the second direction R2.

[0130] For example, the locking part 31 is located between the two limiting parts 35 along the third direction R3.

[0131] In this embodiment, the connector 3 has limiting portions 35 on both sides along the third direction R3. The limiting portions 35 protrude from the locking portion 31 towards the adjusting member 2 along the second direction R2. The adjusting member 2 abuts against the limiting portions 35 on both sides along the third direction R3. The third direction R3 is arranged intersecting the first direction R1 and the second direction R2. The limiting portions 35 can restrict the relative rotation between the adjusting member 2 and the connector 3. When the tightness of the brake cable 20 is adjusted, the operator operates the fastener 1. The adjusting member 2 can restrict the rotation of the connector 3. The operator does not need to use additional tools to fix the connector 3, which simplifies the steps of adjusting the brake cable 20 and improves the efficiency of the operator.

[0132] It is understood that the connecting member 3 may not have a limiting part 35. For example, the guide part 321 of the connecting shaft 32 abuts against the groove wall of the guide groove 21 of the adjusting member 2 along the third direction R3. The walls on both sides of the guide part 321 along the third direction R3 are flat, and the guide part 321 can restrict the relative rotation between the adjusting member 2 and the connecting member 3.

[0133] In some embodiments, the connector 3 is threadedly connected to the fastener 1, and the fastener 1 is used to restrict loosening between the fastener 1 and the connector 3.

[0134] In this embodiment of the disclosure, the connector 3 is threadedly connected to the fastener 1. The fastener 1 is used to restrict the loosening between the fastener 1 and the connector 3. When the adjusting member 2 is in the locked state, it reduces the possibility of the adjusting member 2 moving due to the loosening between the fastener 1 and the connector 3, and reduces the possibility of the brake line 20 loosening.

[0135] It is understood that the connector 3 is not limited to a threaded connection with the fastener 1. Exemplarily, the fastener 1 is snap-fitted to the connector 3.

[0136] In some embodiments, please refer to Figures 1-5 , Figure 8 and Figure 9 Fastener 1 includes a first nut 11 sleeved on the connector 3 and a second nut 12 threadedly connected to the first nut 11. The first nut 11 has a first thread 111 connected to the second nut 12, and the second nut 12 has a second thread 121 connected to the first nut 11. The first thread 111 and the second thread 121 are eccentrically arranged. Alternatively, fastener 1 includes a third nut 15 sleeved on the connector 3 and a first washer 13 and a second washer 14 located between the third nut 15 and the adjusting member 2. The first washer 1... 3 and the second washer 14 are arranged along the second direction R2. The first washer 13 has a first surface 131 on the side facing the second washer 14 and a second surface 141 on the side facing the second washer 14 that contacts the first surface 131. The first surface 131 and the second surface 141 are both arranged intersecting the second direction R2. The first washer 13 has at least two first surfaces 131 along its circumference and the second washer 14 has at least two second surfaces 141 along its circumference.

[0137] For example, fastener 1 is a HardLock eccentric locking nut.

[0138] For example, fastener 1 includes a NordLock wedge washer and a nut.

[0139] In this embodiment of the present disclosure, the fastener 1 includes a first nut 11 sleeved on the connector 3 and a second nut 12 threadedly connected to the first nut 11. The first nut 11 has a first thread 111 connected to the second nut 12, and the second nut 12 has a second thread 121 connected to the first nut 11. The first thread 111 and the second thread 121 are eccentrically arranged to reduce the possibility of the first nut 11 and the second nut 12 loosening, reduce the movement of the adjusting member 2 in the locked state, make the position of the adjusting member 2 and the brake line 20 more stable and reliable, reduce the possibility of the brake adjusting device 10 loosening or moving, and reduce the possibility of the brake line 20 loosening. The first washer 13 and the second washer 14 are arranged along the second direction R2. The first washer 13 has a first surface 131 on the side facing the second washer 14, and the first washer 13 has a second surface 141 that contacts the first surface 131 on the side facing the second washer 14. The first surface 131 and the second surface 141 are both arranged intersecting the second direction R2. The first washer 13 has at least two first surfaces 131 along its circumference, and the second washer 14 has at least two second surfaces 141 along its circumference. The first washer 13 and the second washer 14 prevent the third nut 15 from loosening with the connector 3, reduce the movement of the adjusting member 2 in the locked state, make the position of the adjusting member 2 and the brake cable 20 more stable and reliable, reduce the possibility of the brake adjusting device 10 loosening or moving, and reduce the possibility of the brake cable 20 loosening.

[0140] In some embodiments, the fastener 1 includes a double-layer washer and a wedge-toothed nut. The double-layer washer includes a tapered spring washer and a flat washer. The tapered spring washer is used to prevent loosening, and the flat washer is used for surface pressure to ensure that the double-layer washer is subjected to uniform force and to prevent the tapered spring washer from being crushed and deformed. The thread inside the wedge-toothed nut is a 30° wedge thread.

[0141] In some embodiments, the material of the connector 3 is the same material used to make bolts with a performance grade of 8.8; and / or, the material of the adjusting member 2 is the same material used to make bolts with a performance grade of 8.8.

[0142] It should be noted that the performance grade of a bolt indicates the nominal tensile strength and yield strength ratio of the bolt material. A performance grade of 8.8 means that the nominal tensile strength of the bolt material is 800 MPa, the yield strength ratio is 0.8, and the nominal yield strength is 800 × 0.8 = 640 MPa.

[0143] For example, the material of the adjusting member 2 is ML35 steel or 20MnTiB steel.

[0144] For example, the material of connector 3 is ML35 steel or 20MnTiB steel.

[0145] In this embodiment, the connector 3 is made of the same material used to manufacture bolts with a performance grade of 8.8, which improves the structural strength of the connector 3, facilitates its reuse, and enhances the durability of the brake adjustment device 10. The adjustment component 2 is also made of the same material used to manufacture bolts with a performance grade of 8.8, which improves its structural strength, facilitates its reuse, and enhances the durability of the brake adjustment device 10.

[0146] It is understood that the material of connector 3 is not limited to the material used to make bolts with a performance grade of 8.8. For example, connector 3 is made of steel with a grade of Q235.

[0147] It is understood that the material of the adjusting member 2 is not limited to the material used to manufacture bolts with a performance grade of 8.8. For example, the adjusting member 2 is made of steel with a grade of Q235.

[0148] In some embodiments, please refer to Figures 1-5 , Figure 8 , Figure 11 and Figure 12 The brake body 30 includes a swing arm 302, a reset member 303, and a brake 301. One end of the swing arm 302 is rotatably connected to the brake 301, and the other end of the swing arm 302 is rotatably connected to the connector 3. The brake cable 20 can drive the brake adjustment device 10 to rotate the swing arm 302 to trigger the brake 301 to brake. One end of the reset member 303 abuts against the brake 301, and the other end of the reset member 303 abuts against the swing arm 302.

[0149] For example, the reset member 303 is a torsion spring.

[0150] For example, the reset member 303 is a tension spring.

[0151] For example, brake 301 is a drum brake.

[0152] In this embodiment, the other end of the swing arm 302 is rotatably connected to the connector 3. The brake cable 20 can drive the brake adjustment device 10 to rotate the swing arm 302 to trigger the brake 301. One end of the reset member 303 abuts against the brake 301, and the other end of the reset member 303 abuts against the swing arm 302. When the brake cable 20 is tightened, the brake cable 20 drives the adjustment member 2 and the connector 3 to move, thereby driving the swing arm 302 to rotate to trigger the brake 301. When the brake cable 20 is released, the reset member 303 drives the swing arm 302 to rotate and reset, and the brake 301 stops braking. The reset member 303 is disposed between the swing arm 302 and the brake 301. When the tightness of the brake cable 20 is adjusted by the brake adjustment device 10, the reset member 303 will not affect the operator's operation, thus improving the adjustment efficiency of the brake cable 20.

[0153] It is understood that one end of the reset member 303 is not limited to abutting against the brake 301, and the other end of the reset member 303 is not limited to abutting against the swing arm 302. For example, a fixing bolt is provided on the brake 301, the brake cable 20 passes through the fixing bolt, and a spring is sleeved on the brake cable 20. One end of the spring abuts against the fixing bolt, and the other end of the spring abuts against the adjusting member 2.

[0154] In some embodiments, please refer to Figure 2 , Figure 11 and Figure 12 Projected along the second direction R2, the projection area of ​​the end of the reset member 303 that abuts against the swing arm 302 is outside the projection area of ​​the swing arm 302, and the end of the reset member 303 that abuts against the swing arm 302 is located on the side of the swing arm 302 along the first direction R1 toward the brake line 20.

[0155] For example, the swing arm 302 has a groove on the side facing the brake line 20 along the first direction R1, and the reset member 303 is located in the groove.

[0156] In this embodiment of the present disclosure, when projected along the second direction R2, the projection area of ​​the end of the reset member 303 that abuts against the swing arm 302 is located outside the projection area of ​​the swing arm 302. The end of the reset member 303 that abuts against the swing arm 302 is located on the side of the swing arm 302 along the first direction R1 toward the brake line 20. The end of the reset member 303 will not be blocked by the swing arm 302. The operator can see the end of the reset member 303 from the side of the second direction R2, which is convenient for installing the reset member 303.

[0157] It is understood that, when projected along the second direction R2, the projection area of ​​the end of the reset member 303 that abuts against the swing arm 302 is not limited to being located outside the projection area of ​​the swing arm 302. For example, when projected along the second direction R2, the projection area of ​​the end of the reset member 303 that abuts against the swing arm 302 is located within the projection area of ​​the swing arm 302.

[0158] In some embodiments, please refer to Figure 6 , Figure 7 , Figure 8 and Figure 10 The brake cable 20 includes a main cable 201 connected to each other and a mounting portion 202 protruding radially along the main cable 201. The adjusting member 2 has a mounting groove 25 and a wire passage groove 26 connected to each other. The mounting portion 202 is located in the mounting groove 25. The groove wall of the mounting groove 25 facing the main cable 201 along the first direction R1 is a first wall 251. The first wall 251 abuts against the mounting portion 202 to restrict the movement of the brake cable 20 relative to the adjusting member 2 along the first direction R1. The wire passage groove 26 is located in the first wall 251 and is used to avoid the main cable 201.

[0159] It should be noted that when the adjusting member 2 is in the locked state, there is tension in the brake cable 20. The tension of the brake cable 20 can make the mounting part 202 press tightly against the first wall 251 in the first direction R1. The friction between the brake cable 20 and the first wall 251 can prevent the mounting part 202 from moving in the second direction R2. The mounting part 202 is difficult to disengage from the mounting groove 25, thereby making the installation between the brake cable 20 and the adjusting member 2 secure.

[0160] In this embodiment, the mounting part 202 is located in the mounting groove 25. The groove wall of the mounting groove 25 facing the main line 201 along the first direction R1 is the first wall 251. The first wall 251 abuts against the mounting part 202 to restrict the movement of the brake cable 20 relative to the adjusting member 2 along the first direction R1. The wire passage groove 26 is located on the first wall 251. The abutment between the first wall 251 and the mounting part 202 facilitates the assembly of the adjusting member 2 and the brake cable 20. The brake cable 20 and the adjusting member 2 are two separate components, which facilitates the individual replacement of the brake cable 20 or the adjusting member 2, reducing the maintenance cost of the brake structure.

[0161] It is understood that the first wall 251 is not limited to abutting against the mounting portion 202. Exemplarily, the first wall 251 is bolted to the mounting portion 202.

[0162] In some embodiments, please refer to Figure 6 and Figure 7 The brake adjustment device 10 includes a stop 4 connected to the first wall 251. The stop 4 has a notch 41 communicating with the wire groove 26. The notch 41 is used to avoid the main line 201. The main line 201 is located between the stop 4 and the first wall 251 along the second direction R2. When the adjustment member 2 is in the locked state, it is projected along the second direction R2. The projection area of ​​the main line 201 is located within the projection area of ​​the stop 4, so that the stop 4 can restrict the main line 201 from leaving the wire groove 26 along the second direction R2.

[0163] In this embodiment, the main line 201 is located between the stop member 4 and the first wall 251 along the second direction R2. When the adjusting member 2 is in the locked state, it projects along the second direction R2. The projection area of ​​the main line 201 is located within the projection area of ​​the stop member 4, so that the stop member 4 can restrict the main line 201 from leaving the wire groove 26 along the second direction R2, thereby restricting the mounting part 202 from leaving the mounting groove 25 along the second direction R2, and increasing the assembly stability of the brake line 20 and the adjusting member 2.

[0164] It is understandable that the brake adjustment device 10 may not have a stop 4.

[0165] In some embodiments, the stop 4 and the adjusting member 2 are integrally formed.

[0166] In this embodiment, the stop 4 and the adjusting member 2 are integrally formed, which reduces the number of parts in the brake adjusting device 10 and simplifies the assembly steps of the brake adjusting device 10.

[0167] It is understood that the stop 4 is not limited to being integrally formed with the adjusting member 2. Exemplarily, the stop 4 and the adjusting member 2 are manufactured independently and then assembled.

[0168] In some embodiments, please refer to Figure 8 The first wall 251 is arc-shaped, and the surface of the mounting part 202 that abuts against the first wall 251 is also arc-shaped.

[0169] For example, please refer to Figure 8 The groove walls on opposite sides of the mounting groove 25 along the second direction R2 are the second walls 252. The mounting part 202 is located between the two second walls 252 along the second direction R2 so that the two second walls 252 restrict the movement of the mounting part 202 along the second direction.

[0170] In this embodiment, the first wall 251 is arc-shaped, and the surface of the mounting part 202 that abuts against the first wall 251 is arc-shaped, thereby reducing stress concentration between the first wall 251 and the mounting part 202.

[0171] It is understood that the first wall 251 is not limited to being an arc shape. For example, the first wall 251 is rectangular.

[0172] In some embodiments, the braking structure includes a dust sleeve that is fitted over a portion of the brake line 20.

[0173] In some embodiments, when it is necessary to adjust the tension of the brake cable 20, the fastener 1 is loosened or turned to unlock the adjusting member 2. The adjusting member 2 is then pulled along the first direction R1 to bring the brake cable 20 to a suitable tension. The fastener 1 is then tightened or turned to lock the adjusting member 2. The connecting member 3 has limiting portions 35 on both sides along the third direction R3. The limiting portions abut against the adjusting member 2. When the fastener 1 is tightened or turned, the adjusting member 2 can restrict the rotation of the connecting member 3, eliminating the need for additional tools to fix the connecting member 3. The operator can complete the tensioning and locking of the brake cable 20 with a single tool for tightening or turning the fastener 1. The operator does not need to use multiple tools when adjusting the tension of the brake cable 20, which can improve the operator's efficiency by 50%.

[0174] This disclosure provides an adjusting member 2; please refer to [the relevant documentation]. Figures 1-3 ,as well as Figures 6-8 The adjusting member 2 has a guide groove 21. The direction in which the adjusting member 2 moves to make adjustments is a first direction R1. The guide groove 21 extends along the first direction R1.

[0175] In this embodiment, the adjusting member 2 has a guide groove 21. The direction in which the adjusting member 2 moves to make adjustments is a first direction R1. The guide groove 21 extends along the first direction R1, so that the guide groove 21 can cooperate with the connecting member 3 to better control the moving direction of the adjusting member 2.

[0176] This disclosure provides a connector 3, please refer to... Figures 1-4 , Figure 8 and Figure 11 The connector 3 includes a connector 33, which has a locking part 31 for restricting the movement of the adjuster 2 in the locked state.

[0177] In this embodiment of the present disclosure, the connector 3 includes a connector 33, which has a locking part 31.
