Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle brake pad technology, specifically to an electric motorcycle safety warning optical fiber brake pad. 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 lack effective real-time wear limit monitoring and warning functions. Users often rely solely on experience, abnormal noises, or periodic inspections to determine when to replace them, posing a safety hazard. Secondly, their functions are limited, failing to provide active safety warnings such as lights and sounds to alert pedestrians or vehicles during braking. Thirdly, their status information feedback is insufficient, failing to convert the brake pad's working status into electrical signals for interaction with the vehicle's electronic control system. Therefore, there is an urgent need to design a safety warning fiber optic brake pad for electric motorcycles to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric motorcycle safety warning optical fiber brake pad 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 safety warning fiber optic brake pad for electric motorcycles includes an installation assembly and a brake pad assembly. The brake pad assembly is disposed inside the installation assembly. The brake pad assembly includes a base plate and a brake plate. Two sets of grooves are formed on one outer wall of the brake plate, with three grooves in each set. Two sets of conductive coated fiber sheets are welded to one outer wall of the base plate, with three conductive coated fiber sheets in each set. The brake plate is bolted to one outer wall of the base plate, and the conductive coated fiber sheets are inserted into the grooves. Two sets of contact pieces are provided on one outer wall of the base plate, with three contact pieces in each set. The contact pieces are electrically connected to the conductive coated fiber sheets. Two buzzers are bolted to one outer wall of the base plate. The installation assembly includes a housing. A monitoring module is bolted to one side of the inner wall of the housing, and the monitoring module is electrically connected to the buzzers and contact pieces via wires.

[0008] Furthermore, two ventilation openings are provided on both sides of the outer wall of the outer shell, and a dustproof mesh is glued to the inside of the ventilation opening with adhesive.

[0009] Furthermore, an ear plate is integrally formed on one side of the outer wall of the top of the outer shell, and two through holes are opened on one side of the outer wall of the ear plate.

[0010] Furthermore, a stepped block is integrally formed on one side of the inner wall of the outer shell, and the structure composed of the base plate and the brake plate is slidably inserted into the inside of the outer shell. When the structure composed of the base plate and the brake plate encounters the stepped block, it stops moving.

[0011] Furthermore, an electronic control module is bolted to one side of the inner wall of the outer casing, and the electronic control module is electrically connected to the monitoring module and the buzzer via wires.

[0012] Furthermore, three piston cylinders are bolted to one side of the inner wall of the outer casing, and a piston rod is slidably inserted into one end of each piston cylinder, with one end of the piston rod being fixedly connected to the base plate.

[0013] Furthermore, a spring is bolted to one side of the inner wall of the piston cylinder, and one end of the spring is bolted to one end of the piston rod.

[0014] Furthermore, a cold spark friction block is bolted to the center of the outer wall on one side of the substrate, and an opening groove is provided at the center of the outer wall on one side of the brake plate, and the cold spark friction block is slidably inserted into the opening groove.

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

[0016] (1) This utility model achieves real-time monitoring of the wear degree of brake pads by electrically connecting the conductive coated fiber sheet set on the brake pad assembly with the contact sheet on the substrate and cooperating with the monitoring module in the assembly. When the brake pad wears to the preset limit, it will break the conductive coated fiber sheet in the groove, causing the circuit to break. The monitoring module can then trigger the buzzer to sound an alarm, thus completely changing the traditional lagging method that relies on manual inspection, realizing proactive and accurate safety warning, and greatly eliminating the safety hazards caused by excessive wear of brake pads.

[0017] (2) By adding a cold spark friction block, the present invention generates a cold spark when rubbing against the brake disc during braking. Combined with the sound warning of the buzzer, it forms an active safety warning system integrating sound and light. This system can effectively remind pedestrians and vehicles around when braking, significantly improving riding safety at night or in low visibility environments. At the same time, the combination of ventilation holes on both sides of the shell and dustproof nets can effectively prevent dust and debris from entering the internal precision mechanism while ensuring braking heat dissipation efficiency, ensuring the long-term reliability of the monitoring and execution components.

[0018] (3) The structural design of the mounting component of this utility model is scientific and reasonable. On the one hand, the stepped block integrally formed inside the shell provides a precise mechanical stop point for the brake pad assembly, ensuring the stability and consistency of the braking stroke. On the other hand, the reset mechanism composed of piston cylinder, piston rod and spring can automatically and smoothly reset the brake pad assembly after the brake is released, reducing residual drag friction. This not only ensures braking sensitivity, but also helps to reduce unnecessary wear and energy consumption. Attached Figure Description

[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 electric motorcycle safety warning optical fiber brake pad provided in this embodiment of the utility model includes an installation assembly 1 and a brake pad assembly 2. The brake pad assembly 2 is disposed inside the installation assembly 1. The brake pad assembly 2 includes a base plate 14 and a brake plate 17. Two sets of grooves 18 are formed on one side of the outer wall of the brake plate 17, and each set of grooves 18 has three grooves. Two sets of conductive coated fiber sheets 15 are welded to one side of the outer wall of the base plate 14, and each set of conductive coated fiber sheets 15 has three conductive coated fiber sheets. The brake plate 17 is bolted to one side of the outer wall of the base plate 14. The conductive coated fiber sheets 15 are inserted into the grooves 18. Two sets of contact sheets 20 are provided on one side of the outer wall of the base plate 14, and each set of contact sheets 20 has three contact sheets. The contact sheets 20 are electrically connected to the conductive coated fiber sheets 15. Two buzzers 21 are bolted to one side of the outer wall of the base plate 14. The installation assembly 1 includes a housing 3. A monitoring module 7 is bolted to one side of the inner wall of the housing 3, and the monitoring module 7 is electrically connected to the buzzers 21 and the contact sheets 20 through wires.

[0028] Specifically, in this embodiment, the assembly includes a mounting component 1 and a brake pad assembly 2. The brake pad assembly 2 is disposed inside the mounting component 1. The brake pad assembly 2 includes a base plate 14 and a brake plate 17. Two sets of grooves 18 are formed on one side of the outer wall of the brake plate 17, and each set of grooves 18 has three grooves. Two sets of conductive coated fiber sheets 15 are welded to one side of the outer wall of the base plate 14. The three sets of conductive coated fiber sheets 15 are embedded in the grooves 18 of the brake plate 17, forming a closed circuit with the three sets of contact sheets 20 on the base plate 14. When the brake plate 17 wears down to the bottom of the grooves 18, the conductive coated fiber sheets 15 are worn off, and the circuit is broken. The quantity is three. The brake plate 17 is bolted to the outer wall of one side of the base plate 14. The conductive coated fiber sheet 15 is inserted into the groove 18. Two sets of contact pieces 20 are provided on the outer wall of one side of the base plate 14, and each set of contact pieces 20 has three pieces. The contact pieces 20 are electrically connected to the conductive coated fiber sheet 15. Two buzzers 21 are bolted on the outer wall of one side of the base plate 14. The mounting assembly 1 includes a housing 3. A monitoring module 7 is bolted on one side of the inner wall of the housing 3. After the buzzer 21 receives the circuit breaker signal from the monitoring module 7, it emits an audible alarm, which, together with the cold spark, forms a dual sound and light warning system. The monitoring module 7 is electrically connected to the buzzer 21 and the contact pieces 20 through wires.

[0029] This utility model provides an electric motorcycle safety warning optical fiber brake pad. The conductive coated fiber sheet 15 on the brake pad assembly 2 is electrically connected to the contact sheet 20 on the substrate 14. With the cooperation of the monitoring module 7 in the mounting assembly 1, the wear degree of the brake pad is effectively monitored in real time. When the brake plate 17 wears to the preset limit, the conductive coated fiber sheet 15 in the groove 18 will break, causing the circuit to break. The monitoring module 7 can then trigger the buzzer 21 to sound an alarm. This completely changes the traditional lagging method that relies on manual inspection, realizes active and accurate safety warning, and greatly eliminates the safety hazards caused by excessive wear of the brake pad.

[0030] In one embodiment provided by this utility model, such as Figure 2 As shown, two ventilation openings 5 ​​are opened on both sides of the outer wall of the outer shell 3. The ventilation openings 5 ​​have a dual-channel convection design to accelerate heat dissipation, and a dustproof mesh 6 is glued to the inside of the ventilation openings 5 ​​with adhesive to filter dust.

[0031] In another embodiment provided by this utility model, such as Figure 2As shown, an ear plate 12 is integrally formed on one side of the outer wall of the top of the outer casing 3, and two through holes 13 are opened on one side of the outer wall of the ear plate 12. A stepped block 4 is integrally formed on one side of the inner wall of the outer casing 3. The stepped block 4 restricts the sliding stroke of the base plate 14 and the brake plate 17 to ensure that the braking pressure is stable at a preset threshold. The structure formed by the base plate 14 and the brake plate 17 is slidably inserted into the inside of the outer casing 3. When the structure formed by the base plate 14 and the brake plate 17 stops braking, it encounters the stepped block 4 and stops moving. An electronic control module 8 is bolted to one side of the inner wall of the outer casing 3. The monitoring module 7 detects the circuit status of the contact piece 20 in real time. When any fiber piece breaks and causes the circuit to be disconnected, it immediately sends a signal to the electronic control module 8. After processing the monitoring data, the electronic control module 8 performs two operations simultaneously:

[0032] Activate buzzer 21 local alarm

[0033] The brake pad wear status is converted into a standard electrical signal and transmitted to the vehicle ECU or instrument panel. The electronic control module 8 is electrically connected to the monitoring module 7 and the buzzer 21 via wires. Three piston cylinders 9 are bolted to one side of the inner wall of the housing 3, and a piston rod 11 is slidably inserted into one end of the piston cylinder 9. One end of the piston rod 11 is fixedly connected to the base plate 14. A spring 10 is bolted to one side of the inner wall of the piston cylinder 9. When the brake is released, the spring 10 pushes the piston rod 11 to drive the base plate 14 to reset, reducing residual friction and ensuring that the initial position is restored after each braking action. One end of the spring 10 is bolted to one end of the piston rod 11.

[0034] In another embodiment provided by this utility model, such as Figure 3 As shown, a cold spark friction block 16 is bolted to the center of the outer wall on one side of the substrate 14. The cold spark friction block 16 is installed at the center of the substrate 14 and generates a low-temperature spark when it rubs against the brake disc. It is exposed through the opening groove 19 to achieve visible light warning. An opening groove 19 is opened at the center of the outer wall on one side of the brake plate 17, and the cold spark friction block 16 is slidably inserted into the opening groove 19.

[0035] Working principle: When the brake pad 17 has a normal thickness, the conductive coated fiber sheet 15, pre-welded to the substrate 14, is completely embedded in the groove 18 of the brake pad 17 and protected. The end of the conductive coated fiber sheet 15 maintains a reliable electrical connection with the contact piece 20 on the substrate 14, thus forming a closed circuit. The signal of this circuit is monitored in real time by the monitoring module 7, and the system determines that it is in a normal state. As the number of braking cycles increases, the friction material of the brake pad 17 is continuously consumed, and the thickness gradually decreases. When the wear reaches the preset safety limit thickness, the material at the bottom of the groove 18 is worn through, causing the conductive coated fiber sheet 15 embedded therein to be exposed and come into contact with the brake pad. The brake disc wears down due to friction, and the breakage of the conductive coated fiber sheet 15 breaks the circuit. The monitoring module 7 immediately detects this open circuit signal and identifies it as a "wear limit" state. Subsequently, the monitoring module 7 sends a command directly or through the electronic control module 8 to the buzzer 21, triggering the buzzer 21 to emit a continuous or specific frequency audible alarm, reminding the driver to replace the brake pads immediately. When a braking command is issued, such as squeezing the brake lever, hydraulic or mechanical force pushes the entire brake pad assembly 2, which is fixed to the base plate 14 and the brake plate 17, to slide inward along the housing 3, causing the brake plate 17 to press against the rotating brake disc, generating braking force. During this process, the piston rod 11... The piston retracts into the piston cylinder 9, compressing the spring 10. At the end of the sliding stroke, the combined structure of the base plate 14 and brake plate 17 contacts and stops with the stepped block 4 integrally formed on the inner wall of the outer casing 3. This stepped block 4 acts as a mechanical stop, preventing excessive displacement of the brake pads and ensuring consistency in each braking stroke. When the brake is released, the compressed spring 10 releases its elastic potential energy, pushing the piston rod 11 out, which in turn pushes the base plate 14 and brake plate 17 away from the brake disc, returning them to the waiting braking position. This reset mechanism, composed of the piston cylinder 9, piston rod 11, and spring 10, effectively avoids residual drag and ensures flexible wheel operation. During braking, in addition to... In addition to sounding warnings under set conditions such as wear alarms or nighttime braking, the buzzer 21 can also provide sound warnings. The cold spark friction block 16, installed at the center of the base plate 14, will slightly protrude from the opening slot 19 of the brake plate 17 and generate cold sparks by rubbing against the brake disc. The combination of sound and sparks forms an effective sound and light warning, which can significantly alert pedestrians and vehicles in the vicinity, especially at night. The high heat generated during braking can be dissipated through the ventilation openings 5 ​​on both sides of the housing 3 to form convection, preventing internal components from failing due to high temperature. The dustproof net 6 bonded inside the ventilation openings 5 ​​can effectively block dust, mud, water and other debris from entering the housing 3, protecting the monitoring module 7, the electronic control module 8 and the reset mechanism from contamination.

[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.
