Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle brake pad technology, specifically to an electric motorcycle safety warning brake pad based on friction-generated light. Background Technology

[0002] Electric motorcycle brake pads are a core safety component in the braking system of electric motorcycles, achieving vehicle deceleration or stopping through friction. They typically consist of a metal backing plate and friction material, mounted on the brake disc or brake drum. During braking, they generate braking force through friction with their mating parts, and their performance directly affects the overall braking effect and riding safety of the vehicle.

[0003] A novel safety and wear-resistant brake pad, as described in application number CN201810640937.3 and publication date 20181113, includes a metal backplate. A retaining spring is fixedly connected to the bottom center of the metal backplate. An adhesive layer is fixedly connected to the top surface of the metal backplate. A sound-insulating sheet is fixedly connected to the top surface of the adhesive layer. A heat-insulating layer is fixedly connected to the top surface of the sound-insulating sheet. A friction block is fixedly connected to the top surface of the heat-insulating layer. A protrusion is fixedly connected to the top surface of the friction block. Rivet holes are provided on both sides of the top of the metal backplate near the adhesive layer, and a fixing rod is threaded into the rivet holes. This invention relates to the field of automotive parts technology. This novel safety and wear-resistant brake pad device achieves the purpose of improving brake pad safety, facilitating the observation of brake pad usage, and improving the stability of the brake pad during use through the fixing device. Furthermore, the friction block and protrusion improve the wear resistance of the brake pad.

[0004] Traditional electric motorcycle brake pads lack active optical warning functions during braking, making it difficult to provide clear braking signals to surrounding vehicles and pedestrians under low light conditions. Furthermore, they cannot provide real-time feedback on brake pad wear status, making it difficult for users to perceive when to replace them, thus posing potential safety hazards. Therefore, there is an urgent need to design an electric motorcycle safety warning brake pad based on friction-generated light to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a safety warning brake pad for electric motorcycles based on frictional light generation, so as to solve the above-mentioned shortcomings in the prior art.

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

[0007] A safety warning brake pad for electric motorcycles based on triboluminescence includes a housing assembly and a brake assembly. The brake assembly is disposed inside the housing assembly and includes a base plate. Multiple brake blocks are disposed on one outer wall of the base plate, and a spacer groove is formed between the multiple brake blocks. Multiple through holes are opened on the outer wall of the brake blocks away from the base plate. A light-generating rod is slidably inserted into the through holes. A guide rail is bolted to the outer wall of the base plate near the brake blocks. Several support springs are bolted to the guide rail. One end of the support spring extends into the through hole and is fixedly connected to one end of the light-generating rod.

[0008] Furthermore, each of the brake blocks has a groove on one side of its outer wall, and the brake block is slidably mounted on the guide rail through the groove, with the groove communicating with the through hole.

[0009] Furthermore, a pressure sensor is bolted at the center of the bottom of the inner wall of the through hole, and one end of the pressure sensor is in contact with one end of the light-generating rod.

[0010] Furthermore, the housing assembly includes a housing, and a mounting groove is formed on one outer wall of the housing, into which the base plate is slidably inserted.

[0011] Furthermore, several connecting springs are bolted to one side of the inner wall of the mounting groove, and one end of each connecting spring is connected to the base plate via bolts.

[0012] Furthermore, the outer wall of the base plate facing away from the brake block is integrally formed with multiple heat dissipation fins, and the multiple heat dissipation fins and the multiple connecting springs are distributed alternately.

[0013] Furthermore, ventilation openings are provided on both sides of the outer wall of the housing, and filter screens are bolted into the ventilation openings.

[0014] Furthermore, a support plate is integrally formed on one side of the top of the housing, and two mounting holes are provided on the support plate.

[0015] In the above technical solution, the electric motorcycle safety warning brake pad based on frictional light provided by this utility model has the following beneficial effects:

[0016] (1) The light-generating rod embedded in the brake pad of this utility model generates visible light by rubbing against the brake disc during braking. It radiates outward through the through hole. At the same time, the supporting spring ensures that the light-generating rod always maintains contact pressure with the brake disc, which solves the defect of traditional brake pads without active optical warning. Moreover, in low visibility scenarios such as at night or in fog and haze, the friction light generation can provide intuitive braking signals to surrounding vehicles and pedestrians, reducing the risk of rear-end collisions.

[0017] (2) This utility model installs brake blocks by setting a sliding groove and a guide rail to cooperate, and installs a pressure sensor at the bottom of the through hole. After the brake block wears out, the light-generating rod extends outward under the action of the spring. The pressure sensor can detect the change in the position of the light-generating rod in real time, thereby accurately feeding back the wear state of the brake pads. This design realizes real-time monitoring of the wear degree of the brake pads, reminds users to replace them in time, and avoids safety hazards caused by excessive wear of the brake pads.

[0018] (3) This utility model slides the base plate into the mounting groove of the housing and sets a connecting spring to achieve buffering. At the same time, heat dissipation fins are integrally formed on the back of the base plate and ventilation filters are opened on both sides of the housing, which together form a high-efficiency heat dissipation system. This structure greatly improves the heat dissipation efficiency of the brake pads, effectively suppresses the thermal decay phenomenon during continuous braking, and ensures the stability and reliability of braking performance.

Detailed Implementation

[0029] 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.

[0030] like Figure 1-7 As shown, the present invention provides a safety warning brake pad for electric motorcycles based on frictional light generation, comprising a housing assembly 1 and a brake assembly 2. The brake assembly 2 is disposed inside the housing assembly 1 and includes a base plate 10. Multiple brake blocks 11 are provided on one outer wall of the base plate 10, and a spacer groove 12 is formed between the multiple brake blocks 11. Multiple through holes 13 are opened on the outer wall of the brake blocks 11 away from the base plate 10. A light-generating rod 14 is slidably inserted into the through hole 13. A guide rail 18 is bolted to the outer wall of the base plate 10 near the brake blocks 11. A number of support springs 16 are bolted to the guide rail 18. One end of the support spring 16 extends into the through hole 13 and is fixedly connected to one end of the light-generating rod 14.

[0031] Specifically, in this embodiment, a housing assembly 1 and a brake assembly 2 are included. The brake assembly 2 is disposed inside the housing assembly 1. The brake assembly 2 includes a base plate 10. Multiple brake blocks 11 are provided on one outer wall of the base plate 10. The friction material of the brake blocks 11 is a semi-metallic composite material. Spacing grooves 12 are formed between the multiple brake blocks 11. Multiple through holes 13 are opened on the outer wall of the brake blocks 11 away from the base plate 10. A light-generating rod 14 is slidably inserted into the through hole 13. The light-generating rod 14 is made of zinc sulfide ZnS-based triboluminescent material. The brake blocks 11 are slidably mounted on the guide rail 18 through the sliding groove 19. When worn, the thickness of the brake blocks 11 decreases, and the light-generating rod 14 supports the spring. The spring 16 extends outward under the action of the spring; a guide rail 18 is bolted on the outer wall of the base plate 10 near the brake block 11, and several support springs 16 are bolted on the guide rail 18. When the electric motorcycle brakes, the brake block 11 of the brake assembly 2 contacts and rubs against the brake disc, and the light-generating rod 14 slides in the through hole 13 and rubs against the brake disc. Visible light is generated due to the frictional light-generating effect. One end of the support spring 16 is fixed to the guide rail 18, and the other end pushes the light-generating rod 14 to ensure that it is always in close contact with the brake disc and maintains the light intensity. The light radiates outward through the through hole 13 to form an active optical warning signal; one end of the support spring 16 extends into the through hole 13 and is fixedly connected to one end of the light-generating rod 14.

[0032] This utility model provides a safety warning brake pad for electric motorcycles based on friction-generated light. The light-generating rod 14 embedded in the brake block 11 generates visible light by rubbing against the brake disc during braking. The light radiates outward through the through hole 13. At the same time, the support spring 16 ensures that the light-generating rod 14 always maintains contact pressure with the brake disc. This solves the defect of traditional brake pads that do not have active optical warnings. Moreover, in low visibility scenarios such as at night or in fog and haze, the friction-generated light can provide intuitive braking signals to surrounding vehicles and pedestrians, reducing the risk of rear-end collisions.

[0033] In one embodiment provided by this utility model, such as Figure 3-5 and Figure 7 As shown, each of the multiple brake pads 11 has a groove 19 on one side of its outer wall. The brake pads 11 are slidably mounted on the guide rail 18 through the groove 19. The groove 19 is interconnected with the through hole 13. A pressure sensor 17 is bolted to the center of the bottom of the inner wall of the through hole 13. The pressure sensor 17 is a Honeywell FSS series miniature piezoresistive sensor. The pressure sensor 17 is installed at the bottom of the through hole 13 to detect the rebound pressure of the light-generating rod 14 in real time. When the pressure value decreases, the sensor feeds back wear data to prompt the user to replace the brake pads. One end of the pressure sensor 17 is in contact with one end of the light-generating rod 14.

[0034] In another embodiment provided by this utility model, such as Figure 2As shown, the housing assembly 1 includes a housing 3. A mounting groove 6 is provided on one outer wall of the housing 3. A base plate 10 is slidably inserted into the mounting groove 6. Several connecting springs 7 are bolted to one side of the inner wall of the mounting groove 6. The braking impact force is buffered by the connecting springs 7. The base plate 10 slides in the mounting groove 6 to disperse stress. One end of the connecting spring 7 is connected to the base plate 10 by bolts. Multiple heat dissipation fins 15 are integrally formed on the outer wall of the side of the base plate 10 facing away from the brake block 11. The heat dissipation fins 15 and the connecting springs 7 are staggered to accelerate the dissipation of heat from the back of the base plate 10. Multiple heat dissipation fins 15 and multiple connecting springs 7 are staggered. Ventilation openings 8 are provided on both outer walls of the housing 3. Filters 9 are bolted into the ventilation openings 8. The ventilation openings 8 and filters 9 on both sides of the housing 3 form a forced air cooling channel to suppress the thermal decay of the friction material. A support plate 4 is integrally formed on one side of the top of the housing 3. Two mounting holes 5 are provided on the support plate 4. The mounting holes 5 of the support plate 4 provide a standardized interface. The base plate 10 is slidably inserted into the mounting groove 6 to achieve quick assembly and disassembly.

[0035] Working principle: During braking, the brake caliper pushes the entire housing assembly 1 and the brake assembly 2 installed inside it toward the brake disc. The friction surface of the brake pad 11 first contacts the high-speed rotating brake disc, generating braking force through friction to decelerate the vehicle. While rubbing against the brake disc, the end of the light-generating rod 14 embedded in the through hole 13 of the brake pad 11 also rubs violently against the brake disc. The light-generating rod 14 is made of a special triboluminescent material, which excites visible light under friction. The generated light radiates directly outward through the through hole 13, forming a high-brightness point light source. Multiple light-generating rods 14 form an array of light sources on the surface of the brake pads. In nighttime or low-visibility conditions, it can emit clear and obvious braking warning light signals to the rear and sides of the vehicle, effectively alerting vehicles and pedestrians behind, greatly improving safety. Furthermore, during this friction braking process, when the brake pad 11 is not worn, the support spring 16 is in a pre-compressed state, providing continuous pressure to the light-generating rod 14, ensuring that its end is slightly higher than or flush with the friction surface of the brake pad 11, guaranteeing effective contact and friction with the brake disc. Simultaneously, as the brake pad 11 wears down, its overall thickness decreases, and the light-generating rod 14 also wears down. At this point, the elasticity of the support spring 16 is released, pushing the light-generating rod 14 along the through hole 13 towards... The light-emitting rod 14 extends outwards to automatically compensate for wear, ensuring that it maintains effective contact with the brake disc throughout the brake pad's lifespan and provides a stable luminous warning effect. When the inward end of the light-emitting rod 14 contacts the pressure sensor 17 installed at the bottom of the through hole 13, and when the brake pad 11 and the light-emitting rod 14 wear to their maximum thickness, the outward displacement of the light-emitting rod 14, pushed by the support spring 16, reaches its maximum. This inward displacement causes a significant change in the pressure acting on the pressure sensor 17. The pressure sensor 17 converts this pressure signal into an electrical signal, which can be transmitted to the warning indicator light on the vehicle's dashboard or intelligent display. The terminal system can monitor the wear status of brake pads in real time and accurately, and issue timely replacement warnings to users to avoid safety hazards. During braking, a large amount of heat generated by braking is conducted to the base plate 10 through the brake pad 11. The integrated heat dissipation fins 15 on the back of the base plate 10 greatly increase the heat dissipation area. At the same time, the ventilation openings 8 on both sides of the housing 3 form an air convection channel. The natural wind during vehicle operation can carry away the heat on the heat dissipation fins 15. The filter screen 9 can prevent dust and foreign objects from entering the housing and ensure the long-term effective operation of the heat dissipation system. The staggered distribution of the heat dissipation fins 15 and the connecting spring 7 realizes the optimized utilization of structural space.

[0036] 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.
