Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a brake distributor. Background Art

[0002] In transportation, especially electric bicycles, an efficient braking system, namely the brake, is widely used. This system consists of two handlebar cables and two brake cables, which are closely connected to the brake handles on the left and right sides and the front and rear brake devices. This design allows the driver to achieve synchronous action of the front and rear brakes by operating any one of the brake handles, effectively improving the response speed and safety of the brakes. However, in order to deal with the problem of inconsistent wear of the front and rear brakes in long-term use, the brake system is also equipped with a brake force distribution balance block. The design purpose of this balance block is to ensure that the braking force is always balanced regardless of how the brake pad wear changes, so as to ensure the stability and effect of the brake. However, it is worth noting that the guide block for installing the balance block has a certain amount of activity space in the housing of the brake. Although this design helps to flexibly adjust the balance block, in actual use, when installing the brake cable on the brake, the balance block is often unstable and shakes, which increases the difficulty of installation. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a brake distributor which has the advantages of being more convenient and stable during installation.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A brake distributor comprises a shell, and a movable block and a balancing block movably connected in the shell, the balancing block is pivotally connected to the sliding block, the balancing block is provided with at least two connecting parts for connecting brake cables, the shell is provided with a handle cable passing hole and a brake cable passing hole, the handle cable passing hole and the brake cable passing hole are arranged on opposite sides of the balancing block, and an abutment part is provided on the shell near the brake cable passing hole, and when the brake cable is connected to the connecting part, the connecting part can abut against the corresponding abutment part.

[0006] By adopting the above-mentioned technical solution, it can be seen that since the connecting part can abut on the abutting part, it provides convenience for the installation of the brake cable. During installation, workers can align the connecting part directly with the abutting part for installation without complicated adjustment and calibration, thereby improving the installation efficiency. During installation, the connecting part will not be shifted due to the change in tension generated when installing one side of the brake cable, ensuring that the balance block can still maintain a balanced and stable state when the force is uneven, thereby making the installation more convenient.

[0007] Furthermore, the number of the connecting parts is two, the number of the abutting parts is two, and the two connecting parts are arranged on opposite sides of the pivot axis of the balancing weight.

[0008] By adopting the above-mentioned technical solution, it can be seen that since the connecting parts are symmetrically distributed on the balance block, and the two connecting parts are provided with corresponding abutting parts for support and limitation, the entire structure is more stable when subjected to force, and whether it is the tension from the brake cable or other external forces, it can be evenly distributed to the two connecting parts and the abutting parts, thereby reducing the possibility of deformation of the structure due to uneven force.

[0009] Furthermore, the distance between one of the connecting parts and the pivot axis is greater than the distance between the other connecting part and the pivot axis; or, the distances between the two connecting parts and the pivot axis are equal.

[0010] By adopting the above-mentioned technical solution, it can be known that when the distance between one of the connecting parts and the pivot axis is greater than the distance between the other connecting part and the pivot axis, according to the principle of lever, the farther connecting part will generate a greater torque on the balance block when subjected to the same pulling force, so that the braking force on the side of the farther connecting part will be smaller. By adjusting the distance between the two connecting parts and the pivot axis, the ratio of the braking force on both sides can be accurately controlled, thereby achieving different braking force distribution; when the distance between the two connecting parts and the pivot axis is equal, the two connecting parts will generate the same torque on the balance block when subjected to the same pulling force, so that the braking force on both sides is equal.

[0011] Furthermore, a line connecting the center of the connecting portion and the center of the pivot axis of the balancing weight is a first line, and when the connecting portion abuts against the abutting portion, the first line is perpendicular to the axis of the brake cable passing through the hole.

[0012] By adopting the above-mentioned technical solution, it can be known that when the first connecting line is perpendicular to the axis of the hole through which the brake cable passes, the pulling force applied by the brake cable to the connecting part mainly acts on the balance block in the vertical direction, and the vertical force can minimize the component force generated in the horizontal direction.

[0013] Furthermore, the distance between the axis of the hole through which the brake cable passes and the axis of the pivot axis of the balance weight is L1, and the distance between the center of the connecting portion and the axis of the pivot axis of the balance weight is L2, and L1≤L2.

[0014] By adopting the above-mentioned technical solution, it can be known that L1 is less than or equal to L2, the side of the brake cable passage hole close to the axis of the pivot axis of the balance block is position A, and the side of the axis of the pivot axis away from the balance block is position B. The brake cable passage hole is eccentrically arranged relative to the pivot axis of the balance block. Therefore, when the brake cable is not subjected to force, the brake cable deviates in the direction away from the axis of the balance block at the position where the brake cable passes through the hole, increasing the movable distance between the brake cable and the wall of the brake cable passage hole relative to the axis of the balance block when the brake cable is pulled, thereby reducing the risk of friction between the two when the brake cable is subjected to uneven force, which helps to extend the service life of the brake cable and the brake cable passage hole.

[0015] Furthermore, the movable block is slidably connected to the shell.

[0016] By adopting the above technical solution, it can be known that the sliding connection can reduce friction, and the low-friction sliding connection can reduce the wear between the movable block and the housing, thereby extending the service life of the brake distributor.

[0017] Furthermore, the shell is provided with a guide groove, and the movable block is slidably connected to the shell through the guide groove.

[0018] By adopting the above-mentioned technical solution, the guide groove provides a clear sliding path for the movable block, so that the guide groove has a limiting effect, and the movable block can maintain a relatively stable state during the sliding process, reducing the possibility of deviation or shaking, which helps to improve the overall stability and reliability of the brake distributor, and helps to improve the operating accuracy and response speed of the brake distributor.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2As shown, a brake distributor includes a shell 1, and a movable block 11 and a balancing block 12 movably connected in the shell 1, the balancing block 12 is pivotally connected to the sliding block, and the balancing block 12 is provided with at least two connecting parts 121 for connecting the brake cable 17, the shell 1 is provided with a handle cable passing hole 14 and a brake cable passing hole 15, the handle cable passing hole 14 and the brake cable passing hole 15 are arranged on opposite sides of the balancing block 12, and the shell 1 is provided with an abutting part 13 near the brake cable passing hole 15, and the connecting part 121 abuts against the corresponding abutting part 13.

[0024] It can be understood that since the connecting portion 121 can abut against the abutting portion 13, it provides convenience for the installation of the brake cable 17. During installation, workers can directly align the connecting portion 121 with the abutting portion 13 for installation without complicated adjustment and calibration, thereby improving the installation efficiency. During installation, the connecting portion 121 will not be displaced due to the change in tension generated when installing the brake cable 17 on one side, ensuring that the balance block 12 can still maintain a balanced and stable state when the force is uneven, thereby making the installation more convenient.

[0025] Preferably, the number of the abutting portions 13 is two, and the two connecting portions 121 are disposed on opposite sides of the pivot axis of the balancing weight 12 .

[0026] It can be understood that since the connecting parts 121 are symmetrically distributed on the balance block 12, and the two connecting parts 121 are provided with corresponding abutting parts 13 for support and limitation, the entire structure is more stable when subjected to force. Whether it is the tension from the brake cable 17 or other external forces, it can be evenly distributed to the two connecting parts 121 and the abutting parts 13, thereby reducing the possibility of deformation of the structure due to uneven force.

[0027] It can be further known that in this embodiment, the brake distributor is provided with two connecting parts 121, and each connecting part 121 is provided with an abutment part 13 for limiting, so that the two connecting parts 121 can be effectively fixed and supported. In this way, even when the brake cable 17 is subjected to force, the connecting part 121 can maintain a stable position and state, thereby improving the reliability and stability of braking.

[0028] Preferably, the connection portion 121 may be a hole-shaped structure, and the brake cable 17 may be connected to the connection portion 121 by means of a knot; or, the brake cable 17 may also be connected to the connection portion 121 by means of gluing or the like.

[0029] Preferably, the corners of the connecting portion 121 are configured to be arc-shaped.

[0030] Preferably, the movable block 11 is slidably connected to the shell 1 .

[0031] It can be understood that the dynamic connection can reduce friction, and the low-friction sliding connection can reduce the wear between the movable block 11 and the housing 1, thereby extending the service life of the brake distributor.

[0032] Preferably, a guide groove is provided on the housing 1, and the movable block 11 is slidably connected to the housing 1 through the guide groove.

[0033] It can be understood that the guide groove provides a clear sliding path for the movable block 11, so that the guide groove has a limiting effect, and the movable block 11 can maintain a relatively stable state during the sliding process, reducing the possibility of deviation or shaking, which helps to improve the overall stability and reliability of the brake distributor, and helps to improve the operating accuracy and response speed of the brake distributor.

[0034] In this embodiment, taking a tricycle as an example, a handle cable through hole 14 and a brake cable through hole 15 are provided on the housing 1 of the brake distributor. A handle cable 16 passes through the handle cable through hole 14, one end of which is connected to the handle of the tricycle, and the other end is connected to the balance block 12. A brake cable 17 passes through the brake cable through hole 15, one end of which is respectively connected to the two rear wheels, and the other end is connected to the two connecting parts 121 of the brake distributor. When braking is needed, the driver only needs to operate the handle, and pulling the handle cable 16 will quickly drive the balance block 12 in the brake distributor to move. As the balance block 12 moves, the connecting part 121 will also move synchronously, thereby causing the axial movement of the brake cable 17, thereby finally realizing the braking function of the tricycle and ensuring the safety and stability of driving.

[0035] Preferably, a line connecting the center of the connecting portion 121 and the center of the pivot axis of the balancing weight 12 is a first line, and when the connecting portion 121 abuts against the abutting portion 13 , the first line is perpendicular to the axis of the brake cable passing through the hole 15 .

[0036] In one embodiment, the distance between one of the connecting portions 121 and the pivot axis is greater than the distance between the other connecting portion 121 and the pivot axis.

[0037] It is understandable that when the distance between one of the connecting parts 121 and the pivot axis is greater than the distance between the other connecting part 121 and the pivot axis, according to the lever principle, the farther connecting part 121 will generate a greater torque on the balance block 12 when subjected to the same pulling force, so that the braking force on the side of the farther connecting part 121 will be smaller. By adjusting the distance between the two connecting parts 121 and the pivot axis, the ratio of the braking force on both sides can be accurately controlled, thereby achieving different braking force distribution.

[0038] In another embodiment, the distances between the two connection portions 121 and the pivot axis are equal.

[0039] It is understandable that when the distances between the two connecting portions 121 and the pivot axis are equal, the two connecting portions 121 will generate the same torque on the balancing weight 12 when subjected to the same pulling force, so that the braking forces on both sides are equal.

[0040] Preferably, a line connecting the center of the connecting portion 121 and the center of the pivot axis of the balancing weight 12 is a first line, and when the connecting portion 121 abuts against the abutting portion 13 , the first line is perpendicular to the axis of the brake cable passing through the hole 15 .

[0041] It can be understood that when the first connecting line is perpendicular to the axis of the brake cable passing through the hole 15, the tension applied by the brake cable 17 to the connecting portion 121 mainly acts on the balance block 12 in the vertical direction, and the vertical force can minimize the component force generated in the horizontal direction.

[0042] Preferably, the distance between the axis of the brake cable passing through the hole 15 and the axis of the pivot axis of the balance weight 12 is L1, and the distance between the center of the connecting portion 121 and the axis of the pivot axis of the balance weight 12 is L2, and L1≤L2.

[0043] It can be understood that L1 is less than or equal to L2, the side of the axis of the pivot axis of the balance weight 12 near the brake cable through hole 15 is position A, and the side of the axis of the pivot axis away from the balance weight 12 is position B. When the brake cable is not stressed, the brake cable is close to position B in the brake cable through hole. When the brake cable is unevenly stressed, the connection part 121 is stressed and deviates, thereby driving the brake cable to approach position A. Since L1 is less than or equal to L2, the brake cable 17 has a larger movable distance when it is close to position A. Without increasing the size of the through hole, the friction risk between the two is reduced when the brake cable is unevenly stressed, which helps to extend the service life of the brake cable 17 and the brake cable through hole 15. If the size of the through hole is increased, dust will easily enter and reduce the life of the brake.
