Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle brake pad technology, specifically to a green photoluminescent coating self-luminous brake pad structure. Background Technology

[0002] As a core component of the braking system, the performance of brake pads in electric motorcycles directly affects riding safety. They typically consist of a steel plate (backplate), a heat insulation layer, and friction blocks, generating braking force through friction with the rotating brake disc. With the increasing speed of electric motorcycles, higher demands are placed on the braking efficiency, stability, and additional safety features of brake pads. Currently, mainstream friction materials mostly employ semi-metallic, low-metallic, or ceramic composite materials to ensure braking performance at high temperatures. However, even with upgraded calipers or brake discs, functional deficiencies in the brake pads themselves can still pose safety hazards.

[0003] For example, a motorcycle brake pad assembly with application number CN201720824357.0 and authorization announcement date of 20180316 includes a steel shoe welded component and a brake pad. The steel shoe welded component is formed by welding a brake pad and a frame. The brake pad is bonded to the outer arc surface of the brake pad. The frame has an arc-shaped opening on the side away from the brake pad. The frame has several spaced reinforcing ribs, one end of each reinforcing rib extending towards the brake pad and the other end extending towards the arc-shaped opening. Each reinforcing rib has a chip removal guide surface that extends obliquely from the brake pad towards the arc-shaped opening. The advantages of this utility model are: good structural strength and good chip removal effect.

[0004] Traditional brake pads do not have any light-emitting or warning functions. In nighttime, tunnels, or low-light environments, it is difficult for people to visually recognize the braking action, increasing the risk of rear-end collisions. Furthermore, conventional brake pads need to overcome the initial gap between themselves and the brake disc during the initial braking process, resulting in a slight free travel. This may lead to insufficient braking response and affect braking efficiency in emergency situations. Therefore, there is an urgent need to design a green photoluminescent coating self-luminous brake pad structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a green photoluminescent coating self-luminous brake pad structure to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A green photoluminescent coating self-luminous brake pad structure includes a housing assembly and a brake pad assembly. The brake pad assembly is disposed inside the housing assembly. The brake pad assembly includes a photoluminescent sandwich layer. A frosted layer is bonded to one side of the photoluminescent sandwich layer with an adhesive, and a base layer is bonded to the other side of the photoluminescent sandwich layer with an adhesive. One side of the frosted layer has a frosted surface, and a through groove is formed on the frosted layer. The through groove passes through the photoluminescent sandwich layer and the base layer. The housing assembly includes a shell, and a mounting groove is formed on one side of the shell. The brake pad assembly is mounted inside the mounting groove by a combination of the photoluminescent sandwich layer, the frosted layer, and the base layer.

[0008] Furthermore, the outer wall of the top side of the housing is integrally formed with two ear plates, and a through hole is provided on one side of the outer wall of the ear plates.

[0009] Furthermore, two piston cylinders are bolted to one side of the inner wall of the mounting groove, and a piston rod is slidably inserted into one end of each piston cylinder.

[0010] Furthermore, an installation cylinder is integrally formed at the center of one side of the inner wall of the installation groove, and the installation cylinder is slidably connected to the brake pad assembly through a through groove. A liquid storage cylinder is bolted to the outer wall of one side of the housing, and the liquid storage cylinder and the installation cylinder are interconnected.

[0011] Furthermore, infusion pipes are bolted to both outer walls of the liquid storage cylinder, and the infusion pipes are connected to the piston cylinder.

[0012] Furthermore, the reservoir contains hydraulic oil, which can flow into the piston cylinder through two infusion pipes.

[0013] Furthermore, a piston plate is slidably inserted inside the mounting cylinder and the liquid storage cylinder, and a spring is bolted to the outer wall of one side of the piston plate, and the piston plate is in contact with the hydraulic oil.

[0014] Furthermore, the housing assembly also includes a piston brake block, which is slidably inserted into the mounting cylinder, and one end of the piston brake block is mounted to one end of a spring by a bolt.

[0015] In the above technical solution, the green photoluminescent coating self-luminous brake pad structure provided by this utility model has the following beneficial effects:

[0016] (1) The photoluminescent sandwich layer of this utility model can continuously emit green fluorescence in the dark environment after absorbing natural light or artificial light source, thereby providing obvious visual warning during braking, so that people on the side and rear of the vehicle can identify the braking action in time, effectively reducing the risk of rear-end collision and improving riding safety. The frosted surface of the frosted layer enhances the light scattering effect, making the light emission more uniform and eye-catching, effectively solving the defect of traditional brake pads without warning function. Vehicles or pedestrians on the side and rear can intuitively identify the braking status, greatly reducing the risk of rear-end collision. It is especially suitable for high-speed riding scenarios of electric motorcycles. At the same time, the frosted surface on the frosted layer can enhance the friction efficiency with the brake disc, and the through groove design helps to optimize the structural layout and improve heat dissipation performance.

[0017] (2) This utility model effectively eliminates the initial free stroke of traditional brake pads through a linkage system consisting of piston brake block, spring, piston plate and hydraulic oil. When braking, the piston brake block contacts the brake disc first and is pressed. The spring pushes the piston plate to squeeze the hydraulic oil. The hydraulic oil quickly transmits the pressure to the piston rod in the piston cylinder through the infusion pipe, thereby instantly pushing the brake pad assembly towards the brake disc. This design achieves a braking response with almost zero delay, which is particularly beneficial for rapid braking in emergency situations and improves the efficiency and reliability of the braking system.

[0018] (3) The design of the frosted surface and the through groove of the frosted layer of this utility model can achieve both light emission and rapid braking while also taking into account basic performance. The frosted surface increases the friction coefficient with the brake disc, ensuring braking force. The through groove not only provides sliding space for the mounting cylinder, but also plays a role in heat dissipation and chip removal, which helps to timely remove the high heat and wear debris generated during braking, prevent performance thermal decay, reduce abnormal wear, and thus extend the service life of the brake pads.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown in the figure, the green photoluminescent coating self-luminous brake pad structure provided by this utility model embodiment includes a housing assembly 1 and a brake pad assembly 2. The brake pad assembly 2 is disposed inside the housing assembly 1. The brake pad assembly 2 includes a photoluminescent sandwich layer 16. A frosted layer 17 is bonded to one side of the photoluminescent sandwich layer 16 by an adhesive, and a base layer 18 is bonded to the other side of the photoluminescent sandwich layer 16 by an adhesive. One side of the frosted layer 17 has a frosted surface 20, and a through groove 19 is formed on the frosted layer 17. The through groove 19 passes through the photoluminescent sandwich layer 16 and the base layer 18. The housing assembly 1 includes a housing 3. A mounting groove 6 is formed on one side of the housing 3. The brake pad assembly 2 is mounted inside the mounting groove 6 by the combination of the photoluminescent sandwich layer 16, the frosted layer 17 and the base layer 18.

[0028] Specifically, in this embodiment, it includes a housing assembly 1 and a brake pad assembly 2. The brake pad assembly 2 is disposed inside the housing assembly 1. The brake pad assembly 2 includes a light-gathering sandwich layer 16, which is made of a long afterglow material such as rare earth aluminate. During the day, it absorbs natural light or is irradiated by vehicle headlights and stores energy. At night, it emits green fluorescence by releasing photons. The light is scattered by the frosted surface 20 on the surface of the frosted layer 17, enhancing the visibility range. The frosted layer 17 is bonded to one side of the light-gathering sandwich layer 16 with an adhesive. The frosted layer 17 is made of a ceramic matrix composite material. The base layer 18 is bonded to the other side of the light-gathering sandwich layer 16 with an adhesive. 8. A steel back plate is selected; one side of the frosted layer 17 has a frosted surface 20, and a through groove 19 is provided on the frosted layer 17. The through groove 19 passes through the photoluminescent sandwich layer 16, the frosted layer 17 and the base layer 18, providing a sliding channel for the mounting cylinder 7, and assisting in heat dissipation and chip removal; the through groove 19 passes through the photoluminescent sandwich layer 16 and the base layer 18. The outer shell assembly 1 includes a shell 3, which serves as the main support structure. The mounting groove 6 provided inside the shell 3 is used to accommodate the brake pad assembly 2; the mounting groove 6 is provided on one side of the shell 3, and the brake pad assembly 2 is installed inside the mounting groove 6 through the combination of the photoluminescent sandwich layer 16, the frosted layer 17 and the base layer 18.

[0029] This invention provides a green photoluminescent coating self-luminous brake pad structure. The photoluminescent sandwich layer 16 can continuously emit green fluorescence in the dark after absorbing natural light or artificial light sources, thus providing a clear visual warning during braking. This allows people to the side and rear of the vehicle to recognize the braking action in time, effectively reducing the risk of rear-end collisions and improving riding safety. The frosted surface 20 on the surface of the frosted layer 17 enhances the light scattering effect, making the light emission more uniform and eye-catching. This effectively solves the defect of traditional brake pads without warning function. Vehicles or pedestrians to the side and rear can intuitively recognize the braking status, greatly reducing the risk of rear-end collisions. It is especially suitable for high-speed riding scenarios of electric motorcycles. At the same time, the frosted surface 20 on the frosted layer 17 can enhance the friction efficiency with the brake disc, while the through groove design helps to optimize the structural layout and improve heat dissipation performance.

[0030] In one embodiment provided by this utility model, such as Figure 2-3 As shown, two ear plates 4 are integrally formed on one side of the top outer wall of the housing 3, and a through hole 5 is provided on one side of the outer wall of the ear plate 4. The ear plates 4 integrally formed on the top of the housing 3 are connected to the vehicle body by bolts, and the through hole 5 provides a fixing support point to ensure the overall installation stability.

[0031] In another embodiment provided by this utility model, such as Figure 2-3As shown, two piston cylinders 11 are bolted to one side of the inner wall of the mounting groove 6, and a piston rod 12 is slidably inserted into one end of the piston cylinder 11. An mounting cylinder 7 is integrally formed at the center of one side of the inner wall of the mounting groove 6. The mounting cylinder 7 serves as a guide structure for the piston brake block 10, ensuring axial movement accuracy. Its sliding connection design with the through groove 19 avoids uneven wear. The mounting cylinder 7 is slidably connected to the brake pad assembly 2 through the through groove 19. A liquid storage cylinder 13 is bolted to one side of the outer wall of the housing 3, and the liquid storage cylinder 13 is interconnected with the mounting cylinder 7. Infusion pipes 14 are bolted to both sides of the outer wall of the liquid storage cylinder 13, and the infusion pipes 14 are interconnected with the piston cylinder 11. The liquid storage cylinder 13 stores hydraulic oil 15, which can flow into the piston cylinder 11 through the two infusion pipes 14. A piston plate 8 is slidably inserted into the mounting cylinder 7 and the liquid storage cylinder 13. Pressurized hydraulic oil 15 enters the piston cylinder 11 through the infusion pipe 14, pushing the piston rod 12 outward and forcing the brake pad assembly 2 to press against the brake disc, achieving rapid braking. A spring 9 is bolted to one side of the outer wall of the piston plate 8. After braking, the spring 9 releases its stored energy, pushing the piston plate 8 to reset, and the hydraulic oil 15 flows back to the reservoir 13. The piston rod 12 retracts into the piston cylinder 11, and the brake pad assembly 2 disengages from the brake disc, eliminating drag friction. The piston plate 8 contacts the hydraulic oil 15. The outer shell assembly 1 also includes a piston brake block 10. When braking, the piston brake block 10 contacts the brake disc first and is compressed, pushing the spring 9 to compress, which in turn causes the piston plate 8 to squeeze the hydraulic oil 15 in the reservoir 13. The piston brake block 10 is slidably inserted into the mounting cylinder 7, and one end of the piston brake block 10 is bolted to one end of the spring 9.

[0032] Working principle: During the day or in any well-lit environment, the light-gathering sandwich layer 16 in the brake pad assembly 2 continuously absorbs and stores light energy. This process is a passive process that prepares for visual warnings at night or in low-light environments, requiring no active operation. When braking is needed, the entire brake pad structure moves towards the brake disc under the action of the caliper. During this process, the piston brake block 10, located at the front end of the mounting cylinder 7, contacts the rotating brake disc before the abrasive surface 20 of the brake pad assembly 2. After being squeezed by the brake disc, the piston brake block 10 retracts into the mounting cylinder 7. Moving backward, the spring 9 is compressed via bolts. When compressed, the spring 9 pushes the piston plate 8, bolted to its other end, to slide within the mounting cylinder 7 and the reservoir 13. The movement of the piston plate 8 begins to compress the hydraulic oil 15 in front of it. The pressurized hydraulic oil 15 is rapidly forced from the reservoir 13 through the inlet pipes 14 on both sides into the two piston cylinders 11. The hydraulic oil 15 flowing into the piston cylinders 11 generates pressure, pushing the piston rod 12 inside to extend outward. At this time, the brake pad assembly 2 is still moving forward, and the extended piston rod 12 forcefully presses against the back of the brake pad assembly 2. The combined force of the hydraulic thrust and the caliper's braking force instantly presses the abrasive surface 20 of the brake pad assembly 2 tightly against the brake disc, generating a powerful braking force. The mounting cylinder 7 passes through the through slot 19 on the brake pad assembly 2, ensuring smooth sliding and structural integrity of the entire assembly. When braking ends and the caliper's clamping force is released, the compressed spring 9 begins to recover its deformation, pushing the piston plate 8 to move in the opposite direction, resetting it within the mounting cylinder 7 and the reservoir 13. The resetting motion of the piston plate 8 generates a backflow force in the hydraulic oil 15, causing the hydraulic oil 15 in the piston cylinder 11 to flow back to the reservoir through the infusion pipe 14. 13. The return flow of hydraulic oil 15 causes the piston rod 12 to retract into the piston cylinder 11. At the same time, the piston brake block 10 is also pushed back to its original protruding position by the spring 9, preparing for the next braking. The brake pad assembly 2 separates from the brake disc under the action of the overall mechanism, and the braking process ends. During the braking process and in the dark environment after braking, the light-gathering sandwich layer 16 will release its stored light energy and emit green cold light. The light shines through the translucent frosted layer 17, and its frosted surface 20 makes the light soft and uniform, forming a conspicuous luminous area to continuously warn vehicles and pedestrians behind.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
