Description

Technical Field

[0001] This utility model relates to the field of automotive brake pad backing plate technology, specifically an anti-deformation automotive brake pad backing plate. Background Technology

[0002] Brake pads are an important component of a car's braking system, and their performance directly affects braking effect and driving safety. When brake pads are installed on the brake assembly, the backing plate of traditional brake pads is usually made of metal. Although it has sufficient strength and wear resistance, the brake pads are prone to prolonged high temperatures during braking, which can cause the backing plate to deform and break due to thermal expansion, friction, or excessive load. This deformation can lead to uneven contact between the brake pads and the brake disc, thus affecting the braking effect.

[0003] Therefore, how to achieve brake pad backing plates that are not easily deformed and have better high-temperature resistance is a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant automotive brake pad backing plate. By adding a reinforcing layer, namely a metal mesh and metal corrugated sheets, to the material of the backing plate body, the mesh in the mesh increases the tension of the backing plate itself, and the arc structure in the metal corrugated sheets increases the support of the mesh, thus overcoming the possibility of deformation of the backing plate caused by high temperature and friction, making it less prone to bending, warping and other deformation phenomena. At the same time, the fastening components, limiting sleeves and reinforcing components play a certain limiting role in fixing the backing plate, limiting its displacement during daily use, and keeping it within a certain shape range, reducing and minimizing the deformation of the backing plate caused by thermal expansion. The multiple expansion grooves opened on the surface of the backing plate can, to a certain extent, overcome and release thermal stress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant automotive brake pad backplate, comprising a backplate body, and further comprising a reinforcing layer and a heat insulation layer provided inside the backplate body. The reinforcing layer is embedded with a deformation-resistant metal mesh, and the open portion of the metal mesh is provided with metal corrugated sheets. Multiple expansion grooves are provided on the front surface of the backplate body, and two sets of fastening components, a limiting sleeve, and a reinforcing component are provided on the rear surface of the backplate body. The fastening components include fasteners and fastening seats, and two symmetrically arranged sliding grooves are provided on the rear surface of the backplate body.

[0006] Preferably, an inner plate seat is fixedly installed on the rear surface of the back plate body, and a claw plate is connected to the front surface of the inner plate seat.

[0007] Preferably, the outer surface of the inner plate seat is provided with threads, and the limiting sleeve is provided with a sleeve hole, which is threadedly connected to the inner plate seat through the sleeve hole.

[0008] Preferably, the two slides are located below the limiting sleeve, and the fastening components are provided in two sets, which are respectively distributed in the slides, and the fasteners slide in conjunction with the slides.

[0009] Preferably, each groove has an opening, and multiple equidistant adjusting blocks are installed on the inner surface of each opening.

[0010] Preferably, the rear end of the fastener is movably connected to an extension rod, the end of which is fixedly connected to a fastening seat, and the fastening seat is movably connected to an adjusting block.

[0011] Preferably, the reinforcement assembly includes a support rod, a fastening nut, and two adjusting sleeves, with the two adjusting sleeves located on the left and right sides of the support rod, respectively, and the fastening nut located inside the support rod.

[0012] Preferably, a reinforcing strip is fixedly connected inside each of the two adjusting sleeves. The two reinforcing strips are arranged one after the other and have an overlapping part. The fastening nuts are movably connected to the reinforcing strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In the internal structure of the back panel, this utility model adds a reinforcing layer, namely a metal mesh in the strong layer, to the panel. The support between the meshes and the metal corrugated sheets added in the mesh are used to increase the tension of the back panel itself by using the arc structure in the corrugations. This overcomes the deformation caused by high temperature and friction, making the back panel less prone to bending, warping or breakage.

[0015] 2. In the external structure of the backplate, the present invention uses fastening components, limiting sleeves and reinforcing components to limit the backplate when it is fixed, restricting its displacement during daily use, and keeping it within a certain shape range, reducing the deformation of the backplate caused by thermal expansion. The multiple expansion grooves on the surface of the backplate can effectively release thermal stress to a certain extent and reduce the impact of heat generated by the backplate during the use of the brake pads.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the technical problem that existing brake pads easily reach high temperatures during braking, causing the backing plate to deform and break due to thermal expansion, friction, or excessive load, resulting in uneven contact between the brake pads and the brake disc and thus affecting braking performance, please refer to [link to relevant documentation]. Figures 1-7 The following technical solutions are provided:

[0026] This utility model discloses an anti-deformation automotive brake pad backplate, comprising a backplate body 1, and further comprising a reinforcing layer 11 and a heat insulation layer 12 within the backplate body 1. The reinforcing layer 11 is embedded with an anti-deformation metal mesh 13, and the open portion of the metal mesh 13 is provided with metal corrugated sheets 3. The backplate body 1 can be made of a material with higher hardness, such as magnesium alloy, to increase the hardness of the backplate body 1 itself. The front surface of the backplate body 1 has multiple expansion grooves 9, and the rear surface of the backplate body 1 is provided with two sets of fastening components 8, a limiting sleeve 4, and a reinforcing component 10. The fastening components 8 include fasteners 81 and fastening seats 83. The rear surface of the backplate body 1 has two symmetrically arranged sliding grooves 7. By adding the metal mesh 13 and metal corrugated sheets 3 in the reinforcing layer 11 within the backplate body 1, the tension of the backplate itself can be increased to overcome the deformation caused by high temperature and friction. Furthermore, the corrugated arc shape in the metal corrugated sheets 3 can increase its load-bearing capacity and anti-deformation capacity, making the backplate less prone to bending, warping, or breakage.

[0027] An inner plate seat 5 is fixedly installed on the rear surface of the back plate body 1. A claw plate 51 is connected to the front surface of the inner plate seat 5. The outer surface of the inner plate seat 5 is threaded. A sleeve hole 41 is opened in the limiting sleeve 41 and is threadedly connected to the inner plate seat 5 through the sleeve hole 41. The claw plate 51 is an existing fixing structure for fixing the back plate body 1. However, due to the elasticity of the material of the claw plate 51 itself, the stability of this structure is limited. Therefore, a limiting sleeve 4 is added at the bottom, and the limiting sleeve 4 and the inner plate seat are movable. When the back plate body 1 is installed, the limiting sleeve 4 is extended to the outside of the claw plate 51 by rotating the thread. Figure 5 It can be seen that the ring increases the stability of the tension of the limiting sleeve 4 itself, and at the same time, the limiting sleeve 4 can be locked at the connection of the claw piece 51, which to a certain extent prevents the back plate body 1 from bending.

[0028] Two sliding grooves 7 are located below the limiting sleeve 4. Two sets of fastening components 8 are provided, each distributed within a sliding groove 7. Fasteners 81 slide within the sliding grooves 7. Each sliding groove 7 has an opening 71, and multiple equidistantly distributed adjusting blocks 72 are installed on the inner surface of each opening 71. An extension rod 82 is movably connected to the rear end of each fastener 81. The end of the extension rod 82 is fixedly connected to a fastening seat 83, which is movably connected to the adjusting blocks 72. The two fasteners 81 in the fastening components 8 can be adjusted according to the distance between the backplate body 1 and the caliper at the outer end of the bicycle brake assembly during installation. Stability is increased by utilizing the connection point between the caliper and the backplate body 1. The adjustment range is within the sliding grooves 7. Figure 7 It can be seen that when the fastener 81 is adjusted, it is turned outward to disengage the end fastener 83 from the currently connected adjustment block 72, and moves through the space in the opening 71 until the appropriate position is reached. Then, the fastener 81 is turned in the opposite direction to connect the end fastener 83 with the corresponding adjustment block 72.

[0029] The reinforcement component 10 includes a support rod 101, a fastening nut 103, and two adjusting sleeves 102. The two adjusting sleeves 102 are located on the left and right sides of the support rod 101, respectively. The fastening nut 103 is located inside the support rod 101. A reinforcing strip 104 is fixedly connected to each of the two adjusting sleeves 102. The two reinforcing strips 104 are arranged one behind the other and have overlapping portions. The fastening nut 103 is movably connected to each reinforcing strip 104. Figure 6 It is known that the reinforcing component 10 works in conjunction with the fastening component 8 to increase stability. Both adjusting sleeves 102 have arc-shaped grooves on their outer sides for fitting the fastener 81. During adjustment, the overlapping area between the two reinforcing strips 104 is adjusted by pulling the adjusting sleeves 102 outward or moving them inward, thereby realizing the telescopic function of the reinforcing component 10, so that the structure can be adjusted according to the position of the fastening component 8 as needed.

[0030] Working principle: During the installation of the backplate body 1, the claw 51 is first inserted into the pre-drilled notch in the caliper of the brake assembly. Then, the limiting sleeve 4 is twisted to move it outward until the outer side of the claw 51 is also close to the inner side of the notch. Then, based on the distance between the caliper's inner notch and the two fasteners 81 of the backplate body 1, such as... Figure 7 As shown, when adjusting the fastener 81, turn it outward to disengage the end fastening seat 83 from the currently connected adjusting block 72, and move the fastener 81 through the space in the opening 71 until it fits the inner side of the caliper notch. Then, turn the fastener 81 in the opposite direction to connect the end fastening seat 83 with the corresponding adjusting block 72, which completes the fixing. Then, take out the reinforcement component 10, and fit the fastener 81 with the arc-shaped grooves on the outer side of the two adjusting sleeves 102. Adjust the length of the reinforcement component 10 according to the distance between the two fasteners 81, and finally fix the current length with the fastening nut 103.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
