Description

Technical Field

[0001] This utility model relates to the field of electric vehicle tooling technology, and in particular to a tooling for ensuring the braking stroke of a rear brake. Background Technology

[0002] Electric vehicle manufacturers are required to strictly adhere to national standards for production and testing to ensure the quality and safety of braking systems. In the current domestic market, the application of rear braking systems in electric vehicles is relatively widespread. With the continuous expansion of the electric vehicle market and consumers' increasing focus on safety, the market demand for rear braking systems in electric vehicles is also constantly increasing.

[0003] One of the challenges in the production and assembly process is ensuring consistent rear brake travel across all batches of electric vehicles to prevent defective products. This is especially true when installing the rear brake system, where precise positioning and angle are crucial to ensure even contact between the brake pads and the wheel hub. However, in most finished products, the braking effect varies even for the same displacement of the brake lever. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a rear brake stroke guarantee fixture with a reasonable structure, which can accurately adjust the brake stroke by measuring the displacement of each brake handle to control the brake stroke.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A rear brake travel assurance fixture is clamped onto the vehicle handlebars and, using the handlebars as a reference, measures the swing displacement of the brake lever.

[0007] The structure includes:

[0008] The clamping part connects to the handlebar clamp of the vehicle.

[0009] The measuring unit is located on the swing displacement path of the brake handle and measures the displacement of the brake handle.

[0010] As a further improvement to the above technical solution:

[0011] When the clamping part is connected to the handlebar of the vehicle, the relative position of the measuring part remains constant during the measurement process.

[0012] The measuring part contacts the brake handle, and the brake handle swings along the measuring part.

[0013] The clamping and measuring parts are integrally formed into a single-sided clamping arm, and the tooling is assembled from two single-sided clamping arms.

[0014] A space is formed between the two measuring sections to allow the brake handle to move.

[0015] In the clamped state, the two measuring parts are parallel.

[0016] The units of measurement on the two measuring sections may be the same or different.

[0017] The inner wall of the clamping part is a non-slip arc-shaped surface.

[0018] The beneficial effects of this utility model are as follows:

[0019] This application designs and manufactures a mechanism capable of precisely adjusting the brake stroke, ensuring that the braking system provides stable braking performance under different road conditions and load conditions. It features ease of operation, accurate adjustment, and high durability.

[0020] The tooling provided in this application facilitates the precision machining and assembly of brake components, ensuring that the dimensional accuracy and surface quality of the brake components meet design requirements. This optimizes the assembly process, reduces assembly errors, and improves the overall performance and stability of the braking system.

[0021] By using tooling, we ensure that the braking system's brake stroke is precisely adjustable and that braking performance is stable and reliable. This improves the braking system's response speed and braking force, shortens braking distance, and enhances driving safety.

[0022] This application can also improve the machining accuracy and assembly quality of brake components, reducing maintenance costs caused by component wear or loosening. It extends the service life of the braking system and reduces the frequency and cost of replacing brake components.

[0023] In summary, this application aims to enhance the image and reputation of electric vehicle brands by providing high-quality braking systems and a superior riding experience during vehicle assembly. This, in turn, strengthens consumer trust and satisfaction with the electric vehicle brand, thereby improving market competitiveness. Attached Figure Description

[0024] Figure 1 This is a front view of the overall structure of this utility model.

[0025] Figure 2 This is a three-dimensional view of the overall structure of this utility model.

[0026] The components include: 1. clamping part; 2. measuring part; 3. assembly hole. Detailed Implementation

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the rear brake travel assurance fixture in this embodiment is clamped onto the vehicle handlebars. Using the vehicle handlebars as a reference, the swing displacement of the brake lever is measured.

[0029] The structure includes:

[0030] Clamping part 1 is connected to the handlebar clamp of the vehicle.

[0031] Measurement unit 2 is located on the swing displacement path of the brake handle and measures the displacement of the brake handle.

[0032] When the clamping part 1 is connected to the vehicle handlebar clamp, the relative position of the measuring part 2 remains constant during the measurement process.

[0033] The measuring part 2 contacts the brake handle, and the brake handle swings along the measuring part 2.

[0034] The clamping part 1 and the measuring part 2 are integrally formed as a single-sided clamping arm, and the tooling is formed by assembling two single-sided clamping arms.

[0035] A space is formed between the two measuring sections 2 on both sides, allowing the brake handle to move.

[0036] In the clamped state, the two measuring parts 2 are parallel.

[0037] The scale units on the two measuring sections 2 may be the same or different.

[0038] The inner wall of the clamping part 1 is a non-slip arc-shaped surface.

[0039] The specific structure and working principle of this utility model are as follows:

[0040] like Figure 1 and Figure 2 As shown, the tooling provided in this application is essentially a graduated clamping tool. By clamping this graduated clamping tool onto the vehicle handlebar as a test reference, the movement distance of the brake lever is measured by the measuring unit 2, thereby realizing the control of the brake stroke.

[0041] A fixture consists of two clamping arms, each of which includes a curved clamping part 1 and a straight measuring part 2.

[0042] The clamping parts 1 of the two clamping arms can form an open or closed arc, which can fit perfectly with the vehicle handlebars, making surface contact and close fit with the handlebars, increasing the contact area, thereby ensuring that the relative position of the tooling remains unchanged and the measurement results are accurate during the measurement process.

[0043] To accommodate a wider range of handlebars, as a preferred embodiment, the diameter of the clamping arm can be made slightly larger. By attaching an anti-slip layer, such as a rubber layer, to the inner wall of the clamping part 1, the inner diameter of the clamping part 1 can be reduced, thus accommodating smaller diameter handlebars for women's bicycles, children's bicycles, etc. If it is necessary to accommodate thicker handlebars such as those for men's bicycles, off-road bicycles, or long-distance bicycles, the anti-slip layer can be removed, thereby increasing the inner diameter of the clamping part 1.

[0044] The measuring section 2 is equipped with a scale for precisely controlling the travel of the brake lever. The scales on both measuring sections 2 can use the same unit, allowing readings to be taken from either side of the measuring section 2 where the brake lever is located. Alternatively, two different units can be used, such as domestic centimeters and international inches, facilitating export sales documentation.

[0045] The clamping part 1 and the measuring part 2 adopt an integral molding structure. The clamping arm formed by them has an assembly hole 3 at the inflection point of the clamping part 1 and the measuring part 2. The two clamping arms are connected by pins or bolts in the assembly hole 3 to form a clamp structure.

[0046] This application provides two assembly methods:

[0047] The first type involves a pin penetrating the assembly hole 3 and a spring added between the two clamping arms, so that the two clamping arms and the spring form a spring-loaded clamp. By holding the measuring part 2 and pressing or releasing the measuring part 2, the clamping part 1 can be opened and reset.

[0048] The second type uses threaded holes for mounting holes 3 and screws for connecting parts. When in use, the screws need to be tightened to limit the relative position between the two measuring arms and the vehicle handlebars.

[0049] This application preferably uses the first type of flexible clip assembly structure, which is easier to operate.

[0050] During measurement, the fixture is first clamped onto the vehicle's handlebars, and the angle is adjusted so that the brake lever falls precisely within the space between the two measuring sections 2. The brake lever swings within this space, landing at the corresponding scale mark. During assembly, for different vehicle models, appropriate braking requirements are set. The brake is adjusted to the designated handbrake position to precisely control the braking effect.

[0051] To improve the accuracy of the scale measurement, after clamping, the two measuring parts 2 in this application are required to be parallel to each other to reduce measurement deviation. Alternatively, one of the measuring arms can be directly brought into contact with the brake handle, so that the brake handle moves along the measuring arm.

[0052] The advantage of this application is that it is easy to disassemble and assemble, and will not interfere with other parts during the assembly process. It can quickly adjust the brake to the specified position of the handbrake.

[0053] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
