Description

Technical Field

[0001] This utility model relates to the field of tooling technology for two-wheeled vehicles, and in particular to a brake lever angle positioning device. Background Technology

[0002] Simple electric bicycles lack a positioning mechanism for the brake lever angle. During assembly, the operator relies on feel to control the up-and-down tilt angle of the brake lever. This often results in problems such as the brake lever tilting angle being too high, too low, or inconsistent tilt angles between the left and right brake levers, affecting the rider's driving experience.

[0003] When the brake lever angle is too low, people with small hands will have difficulty squeezing the brake lever, affecting the braking effect and causing safety hazards; if the angle is too high or inconsistent from left to right, it will affect driving comfort. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured brake lever angle positioning device to standardize the brake lever angle of simple electric bicycles and ensure the consistency of brake lever assembly.

[0005] The technical solution adopted in this utility model is as follows: A brake lever angle positioning device includes a base plate, wherein the base plate is provided with: Fix the positioning component to the base plate. The lateral positioning components are symmetrically positioned on both sides of the stem positioning components. Angle positioning components are symmetrically arranged on both sides of the stem positioning component, and are located on the side of the handlebar positioning component opposite to the stem positioning component. The stem positioning assembly, handlebar positioning assembly, and angle positioning assembly are all provided with recessed positions for accommodating the handlebar to be assembled, and the handlebar to be assembled is completely limited by the stem positioning assembly, handlebar positioning assembly, and angle positioning assembly.

[0006] As a further improvement to the above technical solution: The stem positioning component has a stem positioning recess, the handlebar positioning component has a handlebar positioning recess, and the angle positioning component has an angle positioning recess. The openings of the upright positioning recess, the horizontal positioning recess, and the angular positioning recess have different orientations.

[0007] The stand positioning component includes: The support frame is fixedly mounted on the base plate. A stem positioning plate is located at the top of the stem bracket; the stem positioning recess is located on one side edge of the stem positioning plate.

[0008] The single-unit horizontal positioning component includes: The horizontal base is fixedly mounted on the base plate. The horizontal positioning block is located on the horizontal base, and the horizontal positioning recess is formed at the top edge of the horizontal positioning block.

[0009] The open side of the handlebar positioning recess is located on the side of the handlebar positioning block opposite to the handlebar positioning assembly.

[0010] The horizontal positioning block is recessed into the wall on the side opposite to the handlebar positioning component, forming a space to accommodate the handlebar in the direction to be assembled.

[0011] The single-group angle positioning component uses an angle positioning module, and the angle positioning recess is located on the top wall of the angle positioning module.

[0012] The angle positioning recess uses a stepped surface, and the sleeve should contact the stepped surface in the direction to be assembled.

[0013] The gradient change direction of the stepped surface is set radially along the direction to be assembled.

[0014] The direction to be assembled is to place the inverted limit on the brake lever angle positioning device.

[0015] The beneficial effects of this utility model are as follows: This utility model designs a tooling system that first completely limits the handlebar to be assembled by the handlebar stem positioning component and the handlebar cross positioning component, preventing the handlebar from moving in any direction. Then, the left and right brake lever sleeves are assembled. During the assembly process, the brake lever sleeves are limited by the special structure of the top wall of the angle positioning component. When the brake lever sleeves are in contact with the top wall of the angle positioning module, the relative angle between the left and right brake lever sleeves and the handlebar to be assembled is unique, ensuring the accuracy of the assembled product.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the brake lever angle positioning device of this embodiment includes a base plate 1, on which: Fix the positioning component 2 onto the base plate 1. The horizontal positioning component 3 is symmetrically positioned on both sides of the stem positioning component 2. Angle positioning components 4 are symmetrically arranged on both sides of stem positioning components 2, and are located on the side of handlebar positioning components 3 opposite to stem positioning components 2. The handlebar positioning component 2, handlebar lateral positioning component 3, and angle positioning component 4 are all provided with recessed positions for accommodating the handlebar to be assembled, and the handlebar to be assembled is completely limited by the handlebar positioning component 2, handlebar lateral positioning component 3, and angle positioning component 4.

[0022] The handlebar positioning component 2 has a handlebar positioning recess 201, the handlebar positioning component 3 has a handlebar positioning recess 301, and the angle positioning component 4 has an angle positioning recess 401. The openings of the upright positioning recess 201, the horizontal positioning recess 301, and the angular positioning recess 401 have different orientations.

[0023] The stand positioning component 2 includes: The support bracket 202 is fixedly mounted on the base plate 1. The stem positioning plate 203 is located at the top of the stem bracket 202; the stem positioning recess 201 is located at one edge of the stem positioning plate 203.

[0024] The single-unit horizontal positioning component 3 includes: The horizontal base 302 is fixedly mounted on the base plate 1. The horizontal positioning block 303 is placed on the horizontal base 302, and the horizontal positioning recess 301 is formed at the top edge of the horizontal positioning block 303.

[0025] The open side of the horizontal positioning recess 301 is located on the side of the horizontal positioning block 303 that is away from the handlebar positioning assembly 2.

[0026] The horizontal positioning block 303 is recessed into the wall on the side opposite to the handlebar positioning component 2, forming a receiving space 304 that avoids the direction of the handlebar to be assembled.

[0027] The single-group angle positioning component 4 adopts the angle positioning module 402, and the angle positioning recess 401 is located on the top wall of the angle positioning module 402.

[0028] The angular positioning recess 401 uses a stepped surface, and the sleeve will contact the stepped surface in the direction to be assembled.

[0029] The gradient change direction of the stepped surface is set radially along the direction to be assembled.

[0030] The direction to be assembled is to place the inverted limit on the brake lever angle positioning device.

[0031] The specific structure and working principle of this utility model are as follows: like Figure 1 As shown, the tooling of this utility model has a base plate 1, on which five sets of positioning structures are provided: a handlebar positioning component 2 located in the middle, handlebar cross positioning components 3 located on both sides of the handlebar positioning component 2, and angle positioning components 4 located on both sides of the handlebar cross positioning component 3.

[0032] The stem positioning assembly 2 includes a stem bracket 202 that is perpendicular to the base plate 1. The stem bracket 202 adopts a T-shaped structure with ribs. This T-shaped structure is both stable and occupies a small volume in space, making it suitable for limiting irregularly shaped parts such as brake levers.

[0033] A stem positioning plate 203 is provided on the top of the stem bracket 202. For ease of assembly, the stem positioning plate 203 can be designed to be parallel to the base plate 1. Theoretically, there are no special requirements for the stem positioning plate 203; it is sufficient that the stem positioning plate 203 has a stem positioning recess 201 on the side facing the direction to be assembled. The stem of the handlebar in the direction to be assembled is inserted into the stem positioning recess 201.

[0034] Two sets of handlebar positioning components 3 are symmetrically arranged with the handlebar positioning component 2 as the reference. Each set of handlebar positioning components 3 includes a handlebar base 302 and a handlebar positioning block 303 disposed on the handlebar base 302. The handlebar positioning block 303 is waist-shaped on the side away from the handlebar positioning component 2, that is, the handlebar positioning block 303 is recessed inward on one side wall perpendicular to the base plate 1 to avoid the arc corner position of the handlebar to be assembled. A handlebar positioning recess 301 is provided on the top edge of the handlebar positioning block 303. The handlebar positioning recess 301 is located on the side of the handlebar positioning block 303 away from the handlebar positioning component 2. This allows the handlebar to be assembled to be inserted into the handlebar positioning recess 201 and the handlebar positioning recess 301, and then be subject to the limiting force of the handlebar positioning plate 203 and the limiting force of the handlebar positioning recess 301. The two limiting forces are opposite in direction. Ideally, the two forces are perpendicular to each other in space to ensure that the handlebar to be assembled is completely limited.

[0035] When the handlebar to be assembled is first placed upside down on the fixture, the angle positioning component 4 does not contact the handlebar to be assembled. The brake lever sleeve only comes into contact with the top wall of the angle positioning module 402 when the brake lever sleeve is installed. The brake lever sleeve has a glove-like portion and a brake portion, as shown... Figure 2As shown, the top wall of the angle positioning module 402 is set as a stepped surface, wherein the second stepped surface 404 has a recess that fits into the cylindrical glove part; the first stepped surface 403 is a plane that fits into the brake part. The axial installation of the brake lever sleeve is limited by the size of the brake lever sleeve itself, so the angle positioning module 402 only needs to provide a stepped gradient change in the radial direction.

[0036] like Figure 3 As shown, another angle positioning module 402 that can be used in this application is the second step surface 404, which is an arc surface that fits the glove part of the brake lever cover. This structure is more compact.

[0037] The advantage of this application is that by using the stem positioning component 2, the lateral positioning component 3, and the angle positioning component 4, the steering handle and brake lever are positioned, avoiding assembly errors of the left and right brake lever angles and ensuring assembly consistency.
