Description

Technical Field

[0001] The present invention relates to the technical field of temperature monitoring, and in particular to a brake temperature monitoring device. Background Art

[0002] As technology advances with each passing day, vehicle horsepower increases rapidly, and the speed performance leap effectively improves transportation efficiency, but relatively speaking, a high-clamp braking system is required to maintain vehicle driving safety. The vehicle braking system is naturally one of the important mechanisms for controlling vehicle power, and can ensure the driving safety of motorcycles, cars and other public transportation vehicles.

[0003] When the vehicle's brake system is used to brake continuously to reduce speed, the brake pads and brake discs, the brake pads and brake drums, or the brake pads and electromagnetic brake discs will generate resistance through friction between the brake pads and brake discs or between the brake pads and brake drums to slow down or stop the vehicle. Of course, when the vehicle is traveling at high speed, if you want to reduce the speed quickly in a short time, it is inevitable to generate greater friction between the brake pads and brake discs or between the brake pads and brake drums, but this will generate more heat and increase the temperature of the brake system. At this high temperature, it is very easy to reduce the friction coefficient of the brake pads and cause the brakes to be ineffective.

[0004] In addition, excessively high brake temperature will cause the brake oil to vaporize, resulting in the brake oil being unable to transmit braking force, thereby increasing the probability of traffic accidents, leading to the tragedy of major vehicle accidents, and the driver's life safety cannot be guaranteed. Therefore, there are still certain bottlenecks in the existing technical means for the brake safety management system, and there is room and necessity for improvement in this technology.

[0040] In order to make the technical content, purpose of the invention and the effects achieved by the present invention more complete and clear, please refer to the disclosed drawings and figure numbers, and the detailed description is as follows:

[0041] First, see Figure 1 , Figure 2 , Figure 4 , Figure 6 ,as well as Fig. 9 , as shown in the three-dimensional exploded schematic diagram of the brake temperature monitoring device of the present invention, it comprises:

[0042] A plurality of temperature sensing modules 1, each of which is composed of a temperature sensing line 11 and a connector unit 12, wherein the connector unit 12 is connected to an end of the temperature sensing line 11 and installed in the brake system 2 of the vehicle, and the connector unit 12 transmits temperature data of the brake system 2 through the temperature sensing line 11;

[0043] At least one signal transmitter 3 is connected to the temperature sensing line 11, and receives the brake temperature data monitored by the temperature sensing module 1 and transmits the brake temperature signal wirelessly;

[0044] A display unit 4 wirelessly receives the brake temperature signal sent by the signal transmitter 3 and displays multiple groups of brake temperature values ​​monitored by the temperature sensing module 1 on the display unit 4 .

[0045] Further explanation: the brake system 2 of the vehicle is divided into drum type and disc type. The drum brake mainly pivots the shoe 22 with the brake pad 21 on the brake disc 23. When braking, the shoe 22 is thrown outward and rubs against the wheel drum to achieve the braking effect. The disc brake system includes a brake disc 24, a brake caliper 25, a brake pad 21 and brake oil, wherein the brake disc 24 is a rotating disc that rotates with the wheel, and the brake disc 24 can prevent the wheel belt from continuing to rotate and convert kinetic energy into heat energy; the brake caliper 25 is a component attached to the front and / or rear end of the brake disc 23, and the brake pad 21 is a wear-resistant component in contact with the brake disc 24. The brake pad 21 is connected to a back plate 26 and is installed in the brake caliper 25 by connecting with a shaft 27 penetrating the back plate 26. The brake caliper 25 has one or more internal pistons for applying pressure to the brake pad. When the brake pedal is depressed, pressure is generated, forcing the brake fluid to push the piston, causing the brake pad 21 to clamp the brake disc 24, slowing down the vehicle and generating heat.

[0046] See also Figures 1 to 12As shown, when the brake temperature monitoring device of the present invention is actually used and installed, the brake system 2 and the joint unit 12 have several feasible embodiments. The following embodiments are all equipped with temperature sensing modules 1 on four wheel groups of the vehicle, and each temperature sensing module 1 corresponds to a signal transmitter 3. The detailed installation instructions are as follows:

[0047] For example, see Figures 1 to 3 As shown, when the brake temperature monitoring device of the present invention is used in a drum brake system 2, the connector unit 12 at the end of the temperature sensing line 11 has a circular ring portion 121, and the circular ring portion 121 is correspondingly sleeved on the screw member 28 of the pivot shoe 22, so that the screw member 28 is installed and locked together when it is installed on the shoe 22. When the brake system 2 is working, the heat generated by the friction of the brake pad 21 on the shoe 22 can be transferred to the connector unit 12 of the circular ring portion 121, and the connector unit 12 transmits the monitored brake temperature data to the signal transmitter 3 through the temperature sensing line 11. Each group of signal transmitters 3 provides the required power through the built-in power supply unit 31 (using a rechargeable battery), and then transmits the brake temperature signal to the display unit 4 through wireless transmission, and the brake temperature values ​​and power (such as ) monitored by multiple groups of temperature sensing modules 1 are displayed on the display unit 4. Fig.12 As shown). Furthermore, a warning light 41 for generating a warning light signal and an alarm unit 42 for generating a warning sound are provided in the display unit 4. When the brake temperature is too high (exceeding a set value) or abnormal, the warning light 41 and the alarm unit 42 can remind the driver to pay attention to the brake temperature to ensure driving safety.

[0048] For example 2, please refer to Figure 4 and Figure 5 As shown, when the brake temperature monitoring device of the present invention is used in a drum brake system 2, the connector unit 12 at the end of the temperature sensing line 11 has a U-shaped portion 122, and the U-shaped portion 122 is correspondingly inserted into the screw member 28 of the pivot shoe 22, so that the screw member 28 is installed and locked together when it is installed on the shoe 22. When the brake system is working, the heat generated by the friction of the brake pad 21 on the shoe 22 can be transferred to the connector unit 12 of the U-shaped portion 122, and the connector unit 12 transmits the monitored brake temperature data to the signal transmitter 3 through the temperature sensing line 11. Each group of signal transmitters 3 provides the required power through the built-in power supply unit 31 (using a rechargeable battery), and then transmits the brake temperature signal to the display unit 4 through wireless transmission, and the brake temperature values ​​and power (such as the temperature of the brakes) monitored by the multiple groups of temperature sensing modules 1 are displayed on the display unit 4. Fig.12As shown). Furthermore, a warning light 41 for generating a warning light signal and an alarm unit 42 for generating a warning sound are provided in the display unit 4. When the brake temperature is too high (exceeding a set value) or abnormal, the warning light 41 and the alarm unit 42 can remind the driver to pay attention to the brake temperature to ensure driving safety.

[0049] For example 3, please refer to Figures 6 to 8 As shown, when the brake temperature monitoring device of the present invention is used in a disc brake system 2, the connector unit 12 at the end of the temperature sensing line 11 includes an embedded socket 123 and a sensor sheet 124, one end of the embedded socket 123 is correspondingly connected to the temperature sensing line 11, and the other end of the embedded socket 123 is correspondingly inserted and contacted with the sensor sheet 124, and the sensor sheet 124 is correspondingly fixed between the brake pad 21 and the back plate 26. When the brake system is working, the piston is pushed by oil pressure to allow the brake pad 21 to clamp the brake disc 24. The heat generated at this time can be transmitted through the sensor sheet 124 and the embedded socket 123. The temperature sensing line 11 transmits the brake temperature data to the signal transmitter 3. Each group of signal transmitters 3 provides the required power through the built-in power supply unit 31 (using a rechargeable battery), and then transmits the brake temperature signal to the display unit 4 through wireless transmission, and the brake temperature values ​​and power (such as ) monitored by multiple groups of temperature sensing modules 1 are displayed on the display unit 4. Fig.12 As shown). Furthermore, a warning light 41 for generating a warning light signal and an alarm unit 42 for generating a warning sound are provided in the display unit 4. When the brake temperature is too high (exceeding a set value) or abnormal, the warning light 41 and the alarm unit 42 can remind the driver to pay attention to the brake temperature to ensure driving safety.

[0050] Example 4, please refer to Figures 9 to 11 As shown, when the brake temperature monitoring device of the present invention is used in a disc brake system 2, the connector unit 12 at the end of the temperature sensing line 11 includes a socket 123 and a clamp 125. One end of the socket 123 is connected to the temperature sensing line 11, and the other end of the socket 123 is connected to the clamp 125. The clamp 125 is clamped on the shaft 27 connected to the back plate 26 of the brake pad 21 and the brake caliper 25. When the brake system 2 is working, the piston is pushed by oil pressure to make the brake pad 21 clamp the brake disc 24. The heat generated at this time can be transferred through the clamp 125 and the socket 123. The temperature sensing line 11 transmits the brake temperature data to the signal transmitter 3. Each group of signal transmitters 3 provides the required power through the built-in power supply unit (using a rechargeable battery), and then transmits the brake temperature signal to the display unit through wireless transmission. The brake temperature values ​​and power (such as ) monitored by multiple groups of temperature sensing modules 1 are displayed on the display unit 4. Fig.12 As shown). Furthermore, a warning light 41 for generating a warning light signal and an alarm unit 42 for generating a warning sound are provided in the display unit 4. When the brake temperature is too high (exceeding a set value) or abnormal, the warning light 41 and the alarm unit 42 can remind the driver to pay attention to the brake temperature to ensure driving safety.

[0051] Furthermore, the clamp 125 is a U-shaped clamp or a C-shaped clamp.
