Abstract

This utility model relates to the field of brake technology, specifically to a brake with a temperature alarm function, including brake pads and a brake caliper bracket. A through-hole is provided on one upper side of the brake caliper bracket, and a fixing frame block is fixedly installed at one end of the through-hole. Through the locking pin, compression spring, and mounting plate of the locking assembly, different types of temperature sensors and alarm modules can be easily adjusted or disassembled. The operation is simple and efficient, and it can adapt to the installation, fixing, and replacement of temperature sensor modules and alarm modules of different models and sizes. This avoids the problem of incompatibility between the pre-fabricated fixing position on the brake caliper and the module installation interface, preventing the original pre-fabricated fixing position on the brake caliper from being unable to adapt to the installation interfaces of different types of temperature sensors and alarm modules, which would make it difficult to stably fix different types of temperature sensors and alarm modules and affect the normal realization of the temperature monitoring and alarm function.

Description

Technical Field

[0001] This utility model relates to the field of brake technology, specifically to a brake with a temperature alarm function. Background Technology

[0002] When heavy vehicles are in motion, especially on long downhill sections, continuous braking can cause the brake temperature to rise sharply, which can easily lead to brake fade. Braking systems for heavy vehicles use temperature sensors installed in the brake pads or brake shoes. When an abnormal temperature is detected, the safety device will issue an alarm to prevent brake failure due to overheating.

[0003] In existing technology, when the driver presses the brake pedal, the master cylinder pushes the brake fluid, causing the piston of the brake caliper to squeeze the friction pads. The friction pads then contact the rotating brake disc, and the vehicle decelerates through friction. At the same time, a temperature sensor installed near the brake caliper or brake disc continuously collects the temperature of the friction pads or brake disc and transmits the signal to the vehicle control unit (ECU) in real time. The ECU monitors the temperature of the brake pad components in real time through temperature detection elements. When the temperature exceeds a preset safety threshold, an audible and visual alarm or an electrical signal is triggered to remind the operator to stop the machine and check it in time.

[0004] However, there are some shortcomings: the temperature monitoring module sensor and alarm module of the existing brake are usually fixed to the brake caliper of the brake with bolts. The installation method of temperature sensor and alarm module is mainly bolt fixing. The fixing points of traditional brake calipers and the fixing structure of the sensor and alarm module are all pre-made fixed specifications. When it is necessary to replace different models or sizes of temperature sensor modules or alarm modules in actual applications, the original pre-made fixing positions on the brake caliper cannot be adapted to the installation interface of different types of temperature sensors and alarm modules. This makes it difficult to fix different types of temperature sensors and alarm modules stably, affecting the normal realization of temperature monitoring function. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a brake with a temperature alarm function, which can effectively solve the problems mentioned in the background art.

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

[0007] This utility model provides a brake with a temperature alarm function, including a brake pad and a brake caliper bracket. The brake caliper bracket has a through opening on one side near the upper part. A fixing frame block is fixedly installed at one end of the through opening. The inner wall of the fixing frame block has sliding slots at both the upper and lower ends. The upper and lower ends of the fixing frame block are provided with locking components. The locking components are used to facilitate the disassembly, installation and maintenance of the temperature sensor and the audible and visual alarm.

[0008] The locking assembly includes a fixed cylinder, and the upper and lower inner walls of the fixed frame block are provided with fixed holes. The outer wall of the fixed cylinder is fixedly sleeved inside the fixed holes of the fixed frame block. A movable piece is slidably sleeved inside the fixed cylinder. A compression spring is fixedly installed at one end of the movable piece, and the upper end of the compression spring is fixedly installed on the upper part of the inner wall of the fixed cylinder.

[0009] Furthermore, a locking pin is fixedly sleeved inside the movable piece near its center. The locking pin is slidably sleeved inside the fixed cylinder. A handle is fixedly installed at the upper end of the locking pin, and an installation piece is fixedly installed at the lower end of the fixed cylinder.

[0010] Furthermore, the locking pin slides through the interior of the mounting plate, one end of the locking pin slides through the upper and lower ends of the fixing frame, one end of the locking pin is inserted and connected to the fixing plate, and the locking pin is located inside the fixing plate.

[0011] Furthermore, an audible and visual alarm assembly is fixedly installed at the upper and lower ends of the fixing plate, and sliding blocks are fixedly connected to both sides of the upper end of the fixing plate.

[0012] Furthermore, the sliding block is slidably fitted inside the sliding slot of the fixed frame block, and a temperature sensor assembly is fixedly installed at one end of the audible and visual alarm assembly, with one end of the temperature sensor assembly close to the brake pad.

[0013] Furthermore, a sealing plate is fixedly sleeved at one end of the fixed frame block, and an elastic gasket is fixedly pasted on one side of the sealing plate, with the elastic gasket in close contact with one end of the audible and visual alarm assembly.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. This utility model, through the locking pin, compression spring, and mounting plate of the locking component, facilitates the position adjustment or disassembly of different types of temperature sensors and alarm modules. The operation is simple and efficient, and it can adapt to the installation, fixing, and replacement of temperature sensor modules and alarm modules of different models and sizes. It avoids the problem of incompatibility between the pre-made fixing position on the brake caliper and the module installation interface, and avoids the problem of the original pre-made fixing position on the brake caliper not being compatible with the installation interface of different types of temperature sensors and alarm modules, which would make it difficult to fix different types of temperature sensors and alarm modules stably and affect the normal realization of temperature monitoring and alarm functions.

[0016] 2. At the same time, by sliding the fixing plate left and right through the cooperation of the sliding block and the sliding slot, the temperature sensor detection end can be accurately oriented and close to the brake pad, and the elastic pad can be pressed tightly onto the sound and light alarm component by the help of the sealing plate.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] Reference Figures 1 to 3This first embodiment of the present invention discloses a brake with a temperature alarm function, including a brake pad 1 and a brake caliper bracket 2. A through-hole 6 is provided inside the upper part of one side of the brake caliper bracket 2. A fixing frame block 3 is fixedly installed at one end of the through-hole 6. Sliding grooves 31 are provided on the upper and lower ends of the inner wall of the fixing frame block 3. Locking components 5 are provided at the upper and lower ends of the fixing frame block 3. The locking components 5 are used to facilitate the adaptive installation of a temperature sensor and an audible and visual alarm on the brake. When the brake is working, the friction between the brake pad 1 and the brake disc continuously generates heat, which is conducted to the brake caliper bracket 2. This invention, by installing a temperature sensor at the through-hole 6 of the brake caliper bracket 2 using the fixing frame block 3 and the locking components 5, allows the sensor to directly capture the temperature changes of the brake pad 1 or the caliper. The sensor converts the temperature signal into an electrical signal and transmits it to the control module of the audible and visual alarm. The module then... The system measures the temperature against a preset safety threshold. Once the temperature exceeds the threshold, an alarm is immediately triggered, emitting sound and light to alert personnel and prevent brake failure due to high temperatures. Both the temperature sensor component and the audible and visual alarm component 7 are common implementation methods in existing technologies and will not be described in detail here. Common models of temperature sensor components include those adapted to brakes, which need to meet the requirements of high temperature resistance and vibration resistance. For example, the WRN-01K thermocouple has a measurement range covering -200℃ to 1300℃, is resistant to high temperatures and has strong vibration resistance, making it very suitable for high-temperature braking environments. There are also PT100 series such as the WZP-035 platinum resistance thermometer, which has a measurement range of -200℃ to 850℃ and high accuracy (error of only ±0.1℃). Common models of the audible and visual alarm component 7 include the AD16-22SM, which is adapted to AC220V or DC24V voltage, is small in size, supports embedded installation, and is suitable for integration into brakes or vehicle equipment.

[0027] The locking assembly 5 includes a fixed cylinder 51. The upper and lower inner walls of the fixed frame block 3 are provided with fixing holes 57. The outer wall of the fixed cylinder 51 is fixedly sleeved inside the fixing holes 57 of the fixed frame block 3. A movable piece 54 is slidably sleeved inside the fixed cylinder 51. A compression spring 55 is fixedly installed at one end of the movable piece 54. The upper end of the compression spring 55 is fixedly installed at the upper part of the inner wall of the fixed cylinder 51. A locking pin 53 is fixedly sleeved at the center of the movable piece 54. The locking pin 53 is slidably sleeved inside the fixed cylinder 51. A handle 56 is fixedly installed at the upper end of the locking pin 53. An installation piece 52 is fixedly installed at the lower end of the fixed cylinder 51.

[0028] The locking pin 53 slides through the interior of the mounting plate 52. One end of the locking pin 53 slides through the interior of the upper and lower ends of the fixing frame block 3. One end of the locking pin 53 is inserted and connected to the fixing plate 33, and the locking pin 53 is located inside the fixing plate 33.

[0029] In use, firstly, in the locked state, the compression spring 55 is in its naturally extended state, and its elastic force pushes the movable piece 54 downward. The movable piece 54 drives the locking pin 53 to move downward simultaneously. The locking pin 53 slides along the guide structure of the mounting piece 52, passing through the upper and lower ends of the fixing block 3 in sequence, and finally inserts into the fixing piece 33. At this time, the fixing cylinder 51 is connected to the fixing block 3 through the fixing hole 57, and the locking pin 53 connects the fixing block 3 and the fixing piece 33 in series, so that the entire assembly forms a stable connection, completing the installation and fixing of the sensor and alarm. When unlocking is required, by pressing the handle 56 upward, the handle 56 drives the locking pin 53 upward, and the movable piece 54 presses the compression spring 55 upward, causing the spring to contract and store force. As the locking pin 53 gradually moves from the fixing piece 33... The fixed frame 3 is pulled out, and the connection between the fixed frame 3 and the fixed piece 33 is released. At this time, the temperature sensor and alarm can be moved to adjust or disassemble their positions. After releasing the handle 56, the compression spring 55 returns to its extension, pushing the movable piece 54 and the locking pin 53 to move down again and re-inserting into the corresponding hole to complete the locking. Compared with the fixed points, temperature sensors and alarm modules of traditional brake calipers, which are all pre-made fixed specifications, this design can adapt to the installation, fixing and replacing of different models and sizes of temperature sensor modules or alarm modules. This avoids the problem that the original pre-made fixed positions on the brake caliper cannot be adapted to the installation interfaces of different types of temperature sensors and alarm modules, making it difficult to fix different types of temperature sensors and alarm modules stably and affecting the normal realization of temperature monitoring and alarm functions.

[0030] Example 2:

[0031] Reference Figures 2 to 4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: an audible and visual alarm assembly 7 is fixedly installed at the upper and lower ends of the fixing plate 33; sliding blocks 32 are fixedly connected to both sides of the upper end of the fixing plate 33, and the sliding blocks 32 are slidably fitted into the sliding slots 31 of the fixing frame block 3; a temperature sensor assembly 8 is fixedly installed at one end of the audible and visual alarm assembly 7, with one end close to the brake pad 1. The temperature sensor assembly 8 is directly close to the brake pad 1 and can detect the temperature change generated by the brake pad during friction in real time, converting the temperature signal into an electrical signal; a sealing plate 4 is fixedly fitted to one end of the fixing frame block 3, and an elastic gasket is fixedly pasted to one side of the sealing plate 4, and the elastic gasket is in close contact with one end of the audible and visual alarm assembly 7; the temperature sensor assembly 8 transmits the electrical signal to the audible and visual alarm assembly 7; when the temperature of the brake pad 1 exceeds the threshold, the control module of the audible and visual alarm assembly 7 will immediately activate, issuing both an audible alarm (such as a buzzer) and a visual alarm (such as a flashing red light) to remind staff to check for problems such as jamming or excessive wear in the brake.

[0032] In use, fix the audible and visual alarm assembly 7 to the upper and lower ends of the fixing plate 33 (e.g., by screwing it in). Then install the temperature sensor assembly 8 to one end of the audible and visual alarm assembly 7, ensuring that the sensing end of the sensor 8 faces the brake pad 1. Next, align the sliding block 32 of the fixing plate 33 with the sliding slot 31 of the fixing frame block 3, insert it, and slide the fixing plate 33 left and right until the temperature sensor 8 is just close to the brake pad 1. Place the sealing plate 4 on one end of the fixing frame block 3, push the sealing plate 4 to make the elastic gasket press tightly against the audible and visual alarm assembly 7, and then fix the sealing plate 4 to the fixing frame block 3. The position of the fixing plate 33 is locked by the pressure of the elastic gasket, thus completing the installation of the entire device.

[0033] The remaining structure is the same as that in Example 1.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
