Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive brake temperature detection technology, and in particular to a vehicle temperature detection structure. Background Technology
[0002] Brake temperature monitoring is a core component for ensuring driving safety. During braking, the brake pads inside the brake caliper clamp the brake disc under hydraulic pressure, generating tremendous braking force through friction, while also producing a large amount of heat. A sharp rise in brake temperature can directly lead to brake performance degradation or even brake failure. Therefore, real-time and accurate monitoring of the temperature of the brake caliper or its surrounding area is of great significance for assessing the operating status of the braking system, warning of potential risks, and improving vehicle active safety.
[0003] To monitor brake temperature, installing temperature sensors inside the brake caliper housing has become a common technique. Currently, existing technologies primarily employ two methods to mount temperature sensors on brake calipers (especially the caliper housing): The first method involves direct bonding with adhesives (such as adhesive backing). This method suffers from poor stability and low reliability, and the adhesive is prone to aging and detachment at high temperatures, potentially interfering with other vehicle components or posing safety hazards. The second method involves threading the temperature sensor onto the brake caliper housing. While this method improves connection strength, drilling additional threaded holes in the caliper housing directly disrupts its original structural continuity, creating stress concentration points and potentially causing safety hazards.
[0004] Therefore, this utility model provides a vehicle temperature detection structure, thereby enabling the temperature sensor to be reliably installed inside the brake caliper housing without requiring destructive processing of the caliper housing. Utility Model Content

[0029] The present invention will be further described in detail below with reference to specific embodiments:
[0030] like Figures 1 to 9 As shown, a vehicle temperature detection structure is configured on a vehicle braking mechanism and includes a mounting frame 4. The mounting frame 4 includes a first frame 41 and a second frame 42, and a temperature sensor 6 is fixedly mounted on the mounting frame 4.
[0031] The braking mechanism includes a brake caliper housing 2 and a braking unit inside it. A mounting bracket 4 is fixedly installed on the brake caliper housing 2 in a non-destructive installation manner. By firmly installing the mounting bracket 4 on the brake caliper housing 2 and placing the temperature sensor 6 in the braking temperature detection area inside the brake caliper housing 2, the temperature change during the braking process can be monitored in real time and accurately.
[0032] The brake caliper housing 2 includes an inherent hole 21, which is preferably a brake fluid hole or other process hole opened on the brake caliper housing 2.
[0033] like Figure 6 As shown, mounting bracket 4 includes:
[0034] The first frame 41 is detachably connected to the brake caliper housing 2 through the hole 21;
[0035] The second frame 42 is detachably connected to one end of the brake caliper housing 2.
[0036] Both ends of the first frame 41 and the second frame 42, which are far apart, are snapped into the inside of the brake caliper housing 2. The mounting bracket 4 adopts a segmented splicing structure composed of the first frame 41 and the second frame 42. This design allows the mounting bracket 4 to flexibly adapt to the complex internal space and external contour of the brake caliper housing 2, significantly reducing the assembly difficulty and improving the installation efficiency and maintainability.
[0037] Furthermore, the mounting bracket 4 is detachably connected and installed by utilizing the inherent holes 21 on the brake caliper housing 2. This installation method does not require additional drilling or welding or other destructive processing of the brake caliper housing 2, thus completely preserving the original structural strength and sealing of the brake caliper housing 2.
[0038] The first frame 41 and / or the second frame 42 are provided with built-in wiring structures for the wiring of the temperature sensor 6. The connection line of the temperature sensor 6 passes through the wiring structure, thereby protecting the line of the temperature sensor 6 within the wiring structure channel. After passing through, it is connected to the external signal processing unit, which greatly improves the signal transmission stability.
[0039] The first frame 41 has a first wiring channel 411 inside, and a first wire hole 412 is provided on a section of the first frame 41 above the brake caliper housing 2. The first wiring channel 411 and the first wire hole 412 are connected.
[0040] The second frame 42 has a second wiring channel 421 inside, and a second wire hole 422 is provided on a section of the second frame 42 above the brake caliper housing 2. The second wiring channel 421 and the second wire hole 422 are connected.
[0041] like Figure 7As shown, connecting brackets 43 are provided at positions close to the first frame 41 and the second frame 42. The first frame 41 and the second frame 42 are spliced and fixed by bolts connecting the connecting brackets 43. After the first frame 41 and the second frame 42 are installed in place, the connecting brackets 43 on them will be aligned with each other. Each connecting bracket 43 has through holes for connection. Screws can be passed through the through holes of two adjacent connecting brackets 43 and tightened with nuts to fix them.
[0042] like Figure 3 , Figure 8 and Figure 9 As shown, at least one limiting rod 44 is provided on one side of the first frame 41 located within the hole 21. Both ends of the limiting rod 44 abut against one side of the first frame 41 and the other side of the hole 21. One end of the limiting rod 44 is fixedly connected to or integrally formed with the body of the first frame 41, while the other end elastically or rigidly abuts against the inner wall of the hole 21. In this way, the limiting rod 44 forms a radial support between the first frame 41 and the hole 21, effectively filling the assembly gap between them.
[0043] The second frame 42 is provided with at least one limiting rod 44 on one side of the inner cavity of the brake caliper housing 2. Both ends of the limiting rod 44 abut against one side of the second frame 42 and the inner side of the brake caliper housing 2. One end of the limiting rod 44 is fixedly connected to or integrally formed with the body of the second frame 42, while the other end elastically or rigidly abuts against the inner wall of the brake caliper housing 2. In this way, the limiting rod 44 forms a radial support between the second frame 42 and the brake caliper housing 2, effectively filling the assembly gap between them.
[0044] By positioning the first frame 41 and the second frame 42 respectively through all the limit rods 44, the overall positioning of the mounting frame 4 is achieved, preventing the entire mounting frame 4 from radially shaking in the vibration environment of vehicle travel. This helps the temperature sensor 6 to remain stable in the vibration environment, thereby ensuring the accuracy of temperature readings.
[0045] like Figure 2 and Figure 3 As shown, the braking mechanism includes a drive mechanism and a pair of brake pads 3. A brake disc 1 is disposed between the two brake pads 3. A wheel hub 5 is inserted through the center of the brake disc 1. The drive mechanism is connected to the brake pads 3 and can drive the brake pads 3 to move inward relative to each other along the axial direction until they come into frictional contact with the two side surfaces of the brake disc 1, thereby generating braking force.
[0046] At least one end of the mounting bracket 4 is provided with a placement bracket 45 for mounting the temperature sensor 6. After installation, the detection probe of the temperature sensor 6 is close to the surface of the brake disc 1. This helps to minimize the delay and attenuation caused by heat conduction through the air and brake caliper housing 2, thereby ensuring the real-time performance and accuracy of temperature measurement.
[0047] Working principle:
[0048] The mounting bracket 4 is installed using the pre-existing holes 21 on the brake caliper housing 2. The first bracket 41 passes through the holes 21 and is radially positioned and stabilized by a limiting rod 44. The second bracket 42 is installed at the end of the brake caliper housing 2. The two are joined together by a connecting bracket 43 and bolts to form a stable platform spanning and fixed to the brake caliper housing 2. At least one end of the mounting bracket 4 extending into the brake caliper housing 2 is provided with a placement bracket 45 for a temperature sensor 6. Simultaneously, the wiring of the temperature sensor 6 is connected to an external signal processing unit through a wiring structure. The entire wiring path is completely enclosed and protected, effectively preventing the wiring from being worn, directly baked by high temperatures, or contaminated by oil, greatly improving the system's reliability and service life. This preserves the structural integrity and original strength of the brake caliper housing 2.
[0049] During braking, the drive mechanism drives the two brake pads 3 to move inward relative to each other along the axial direction of the brake disc 1. Intense friction occurs between the brake pads 3 and the brake disc 1, efficiently converting the kinetic energy of the vehicle into heat energy, thereby slowing down or stopping the vehicle. Simultaneously, a temperature sensor 6 located near the surface of the brake disc 1 directly and quickly senses the heat radiated by the brake disc 1 after frictional heating.
