Description
Technical Field
[0001] The utility model relates to the technical field of brake assist mechanisms, in particular to a brake reducer. Background Art
[0002] Except for some vehicles that use electronic handbrakes, due to cost factors, sightseeing buses operating in scenic spots or schools generally use a mechanical handbrake structure. The effect of a mechanical handbrake is no different from that of an electronic handbrake. The only disadvantage is that it becomes more difficult to use the handbrake as the usage time increases or due to the driver's physical factors. The existing solution is generally to continue to use an external structure to extend the end of the handbrake. This solution is relatively simple and has better effects, but the disadvantage is that the handbrake extension structure can only be set at the front end. When there is insufficient space, this method cannot be applied. Utility Model Content
[0003] In order to solve the problem that some of the above-mentioned handbrake extension structures cannot be used due to space limitations, the utility model provides a brake reducer.
[0004] The technical solution of this utility model is as follows:
[0005] A brake force reducer comprises a reference frame detachably arranged on a vehicle armrest frame, wherein the reference frame is provided with a rotating seat, and the rotating seat can move along the length direction of the reference frame;
[0006] The rotating seat is rotatably connected to a power-assisting arm, and the rotation plane where the power-assisting arm is located is parallel to the rotation plane where the hand brake is located;
[0007] One end of the power-assisting arm is connected to the end of the handbrake through an adjusting member, and the power-assisting arm can rotate synchronously with the handbrake;
[0008] The adjusting member comprises a rotating slide rail and a rotating slider which can move on the rotating slide rail. The rotating slider and the rotating slide rail are respectively rotatably connected with the power-assisting arm and the hand brake.
[0009] It can be used on any vehicle structure that uses a handbrake. By using this device, the force can be reduced, so that the handbrake can be better controlled, and the above structure can be freely disassembled and assembled, so it can be freely increased or decreased according to the needs of the user.
[0010] In order to ensure the force reduction effect, the linear distance between the end of the power-assisting arm and the handbrake fixed end relative to the rotation axis is smaller than the linear distance between the other end of the power-assisting arm and the rotation axis.
[0011] In order to be applicable to different hand brakes, the reference frame can rotate, and the rotation plane is parallel to the rotation plane of the power-assisting arm. The position of the power-assisting arm can be adjusted by rotating the reference frame.
[0012] The method for realizing the rotation adjustment of the reference frame is that the reference frame is rotationally connected to the handrail frame through a fixed rotating shaft, and one end of the reference frame is fixed to the handrail frame through a positioning pin, and the other end is provided with an adjustment slot, and the rotating seat is provided in the adjustment slot. By changing the position of the positioning pin, the state of the reference frame can be changed at the position around the fixed rotating shaft.
[0013] The method for fixing the rotating seat is that one end of the rotating seat is an enlarged end, and a thread is arranged on the outside and the reference frame is clamped and fixed by a nut, and the booster arm is provided with a rotating shaft passing through the rotating seat. The above method can achieve fixing at any position of the adjusting slot.
[0014] As a preferred solution, a grip is provided at the end of the booster arm away from the handbrake, so as to facilitate the user to hold it.
[0015] In order to facilitate the disassembly and assembly of the above structure relative to the handbrake, the rotating slide rail is detachably connected to the end of the handbrake by bolts.
[0016] As a preferred solution, the booster arm is S-shaped, which is convenient for holding and using.
[0017] The specific structure of the booster arm is that the booster arm comprises a first C-shaped segment and a second C-shaped segment, and the rotation axis is arranged in the middle of the first C-shaped segment, so that the booster arm can achieve the effect of reducing force.
[0018] The beneficial effects of the utility model are as follows: the utility model is a brake reducer, which can reduce force through the power-assisting arm, thereby making the operation of tightening the handbrake more labor-saving, and the above-mentioned structure can be applied to different vehicles. According to the specific design requirements of the corresponding vehicle, the position and use angle of the power-assisting arm can be changed by adjusting the position of the long hole of the rotating seat and the angle of the reference frame. It is not limited to being set at the front end of the handbrake, but can also be set at the upper end or rear end. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example
[0029] like Figure 4 The brake reducer shown comprises a reference frame 4 detachably arranged on a vehicle armrest frame 2, wherein the reference frame 4 is used to provide support to ensure that a booster arm 6 rotatably connected thereto can tighten the handbrake with reference to the reference frame 4.
[0030] In order to be suitable for use in vehicles of different models and specifications, it should be noted that the base frame 4 is provided with a rotating seat 5, and the rotating seat 5 can move along the length direction of the base frame 4, that is, the rotating seat 5 used to set the power-assisting arm 6 can move in the vertical direction and the horizontal direction. In this way, the setting position of the power-assisting arm 6 relative to the handbrake can be changed, so that the setting position of the force reducer can be adjusted according to the actual space conditions of the vehicle, which is different from the setting method of the external extension structure of the handbrake, and it can be used for reducing the force of the handbrake at a position other than the front end of the handbrake.
[0031] Afterwards, if Figure 1-5 As shown, the rotating seat 5 is rotatably connected to the power-assisting arm 6 to ensure that the power-assisting arm 6 can drive the handbrake to rotate by rotating, and the rotating plane where the power-assisting arm 6 is located is parallel to the rotating plane where the handbrake 3 is located. The parallel rotating planes can ensure the driving effect.
[0032] It should be noted that in the above structure, one end of the power-assisting arm 6 is connected to the end of the handbrake 3 through the adjusting member 7, and the power-assisting arm 6 can rotate synchronously with the handbrake 3. Since the rotation axes of the power-assisting arm 6 and the handbrake 3 are not on the same straight line, it is necessary to set the adjusting member 7 to solve the above problem. The setting of the adjusting member 7 can ensure that while the end of the power-assisting arm 6 rotates around the rotation axis, it can also drive the end of the handbrake 3 to rotate synchronously around the rotation axis.
[0033] And in the above structure, the specific structure of the above-mentioned adjusting member 7 is that the above-mentioned adjusting member 7 includes a rotating slide rail 72 and a rotating slider 71 that can move on the rotating slide rail 72, and the rotating slider 71 and the rotating slide rail 72 are respectively rotatably connected to the power-assisting arm 6 and the handbrake 3. When the end of the above-mentioned power-assisting arm 6 rotates and moves, the above-mentioned rotating slider 71 can move synchronously, and in this process, it can move relative to the rotating slide rail 72 and drive it to rotate. Accordingly, the handbrake 3 can be driven to rotate in this way, and the displacement of the end can be adjusted and adapted by the movement of the rotating slider 71 relative to the rotating slide rail 72.
[0034] Since the present device adopts the lever principle by reducing force, in order to ensure the force reduction effect, the linear distance between the end of the power-assisting arm 6 and the handbrake 3 fixed relative to the rotation axis is smaller than the linear distance between the other end of the power-assisting arm 6 and the rotation axis. In other words, the distance between the end of the power-assisting arm 6 rotated by the driver and the rotation axis needs to be larger than the other end, and the larger the length difference, the better the force reduction effect, but the corresponding occupied space is larger, so the setting position of the rotation axis of the power-assisting arm 6 needs to be set according to the needs.
[0035] Generally, as a common choice, the booster arm 6 is S-shaped, which is convenient to hold and use. The specific structure of the booster arm 6 is that the booster arm 6 includes a first C-shaped segment and a second C-shaped segment, and the rotation axis is arranged in the middle of the first C-shaped segment, which can make the booster arm 6 achieve the effect of reducing force.
[0036] Afterwards, based on the above design, in order to facilitate holding, the end of the booster arm 6 away from the handbrake 3 is provided with a grip 61, which is convenient for users to hold. And after the grip 61 is anti-slip treated, it is more convenient to use.
[0037] The above structure can be used on any vehicle structure that uses the handbrake 3. By using this device, the force can be reduced, so that the handbrake 3 can be better controlled. The above structure can be freely disassembled and assembled, so that it can be freely increased or decreased according to the needs of the user. And it is not limited to the front setting, such as Figure 3 , 5 As shown, according to the needs of the user and the limitation of the vehicle space, the device can be set at different positions for application.
[0038] In the above structure, the method for adjusting the position is that, in order to be suitable for different handbrakes 3, the reference frame 4 can rotate, and the rotation plane is parallel to the rotation plane of the booster arm 6. The position of the booster arm 6 can be adjusted by rotating the reference frame 4.
[0039] Afterwards, based on the above structure, the reference frame 4 is further rotatably adjusted in the following manner: the reference frame 4 is rotatably connected to the handrail frame 2 via a fixed rotating shaft 41, and one end of the reference frame 4 is fixed to the handrail frame 2 via a positioning pin 42, and an adjustment slot 43 is provided at the other end, and the rotating seat 5 is provided in the adjustment slot 43. By changing the position of the positioning pin 42, the state of the reference frame 4 can be changed at a position around the fixed rotating shaft 41. And if the power-assisting arm 6 needs to be set at a different position, the position of the fixed rotating shaft 41 can also be adjusted as required, that is, Figure 3 , 5 As shown, after the position of the fixed shaft 41 is determined, the position of the positioning pin 42 can be determined.
[0040] In the above structure, the rotating seat 5 is fixed in such a way that one end of the rotating seat 5 is an enlarged end, and a thread is arranged on the outside and the reference frame 4 is clamped and fixed by a nut, and the booster arm 6 is provided with a rotating shaft passing through the rotating seat 5. The above method can achieve fixing at any position of the adjusting long hole 43.
[0041] Finally, in order to facilitate the disassembly and assembly of the above structure relative to the handbrake 3, the rotating slide rail 72 is detachably connected to the end of the handbrake 3 by bolts.
