[0002] Fixing parts are suitable for fixing two parts of an object. In a car, fixing parts are used for both wiring harnesses and exhaust pipes. The exhaust pipe of a car is generally fixed to the bottom of the car by clamps and bolts.

[0003] However, in practice, people have noticed that with frequent use of the car or after collision with debris on the ground, the clamps and threads that fix the exhaust pipe are prone to loosening, causing the exhaust pipe to hang in the air, damaging the connection between the exhaust pipe and the engine, and after one end of the exhaust pipe is suspended in the air, the car host will not display vehicle abnormalities, which may lead to failure to discover the abnormality in time and cause the entire exhaust pipe to be damaged. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing part for connecting an automobile structure, which is applied to a pressure sensor through a pressure plate by the reaction force of a spring. When the connection of the exhaust pipe is loosened and suspended in the air, the pressure on the pressure sensor disappears, and the signal originally transmitted to the vehicle computer system disappears, so that the vehicle computer issues a prompt, which facilitates timely discovery when the exhaust pipe falls off.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixing member for connecting an automobile frame, comprising

[0007] A fixing assembly, wherein the fixing assembly comprises a base, and a groove is arranged on the base, and a bolt hole for positioning is also opened on the inner side of the fixing assembly;

[0008] A spring and a pressure plate are placed on the fixing assembly, and the spring is located between the fixing assembly and the pressure plate, wherein a pressure sensor for detecting whether the exhaust pipe is loose is also arranged on the pressure plate.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the embodiment of the utility model provides a fixing member for connecting an automobile frame, comprising

[0027] A fixing assembly 1, wherein the fixing assembly 1 comprises a base 11, and a groove 12 is provided on the base 11, and a bolt hole 14 for positioning is also provided on the inner side of the fixing assembly 1;

[0028] A spring 2 and a pressure plate 3 are placed on the fixing component 1, and the spring 2 is located between the fixing component 1 and the pressure plate 3, and can push the pressure plate 3 to interact up and down, wherein the pressure plate 3 is also provided with a pressure sensor 4 for detecting whether the exhaust pipe is loose.

[0029] The end of the spring 2 is located inside the positioning groove 13 , and the other end of the spring 2 is fixed to the pressure plate 3 to position the end of the spring 2 .

[0030] As a further technical solution of the utility model, a connecting seat 5 and a clamping piece 6 are further provided on the fixing assembly 1, and the two ends of the clamping piece 6 are close to each other after passing through the inner side of the connecting seat 5, and the exhaust pipe can be fixed with bolts after passing through the inner side of the clamping piece 6. Two connecting seats 5 and two clamping pieces 6 are respectively provided to delay the falling-off time of the connection, and through holes for passing bolts are opened at both ends of the clamping piece 6.

[0031] As a further technical solution of the utility model, both ends of the pressing plate 3 are provided with concave sliding grooves, so that the pressing plate 3 can slide in the up and down directions, and the sliding grooves are slidably connected to the connecting seats 5 on the left and right sides of the pressing plate 3.

[0032] As a further technical solution of the utility model, an arc groove is provided on the connecting seat 5 , the connecting seat 5 is fixed to both ends of the upper part of the base 11 , and the end surface of the connecting seat 5 is aligned with the end surface of the groove 12 .

[0033] As a further technical solution of the present invention, a rectangular boss is integrally provided at the bottom of the base 11, and the rectangular boss is located below the bolt hole 14, and the bolt hole 14 is through-through from top to bottom.

[0034] By adopting the above technical solution, the exhaust pipe is pushed to move in the direction of the spring 2 and then fixed. At this time, the surface of the pressure sensor 4 fits with the surface of the exhaust pipe, and the reaction force of the spring 2 after being stressed will be applied to the pressure sensor 4 through the pressure plate 3. When the exhaust pipe falls off, the pressure acting on the pressure sensor 4 disappears, and the vehicle system will detect the abnormality and remind the owner, so that the owner can find the abnormality in time.

[0035] In this embodiment, the pressure sensor 4 is mainly composed of a pressure sensitive element for sensing pressure and a signal processing unit. The pressure sensitive element will generate an electrical signal when subjected to pressure. The signal processing unit converts the generated electrical signal and then transmits the converted signal to the vehicle system through a wire to realize monitoring of the connection point.

[0036] In this embodiment, the bolt holes 14 are respectively located at the four corners of the base 11, and the grooves 12 are symmetrically arranged on the left and right sides of the positioning groove 13 to prevent the bottom of the spring 2 from moving after being compressed.

[0037] In this embodiment, the upper portion of the pressure sensor 4 is higher than the upper portion of the connecting seat 5 , so that after the exhaust pipe is fixed, downward pressure is applied to the pressure sensor 4 .

[0038] The working principle of the utility model is as follows: when in use, the exhaust pipe is passed through the inner side of the hoop plate 6, and the exhaust pipe is pushed to move in the direction of the spring 2. At this time, the surface of the pressure sensor 4 is in contact with the surface of the exhaust pipe, and the reaction force of the spring 2 after being stressed will be applied to the pressure sensor 4 through the pressure plate 3. The pressure sensitive element inside the pressure sensor 4 will generate an electrical signal after being stressed, and the electrical signal is sent to the vehicle system after being converted by the signal processing unit through the wire. After receiving the signal, the vehicle system determines that the exhaust pipe connection is firmly connected, and then the bolt is passed through the through holes at both ends of the hoop plate 6 and locked with a nut, and then the bolt is inserted into the inner side of the bolt hole 14, and the end of the bolt is fixed to the bottom of the automobile component. When the connection between the hoop plate 6 and the exhaust pipe is loosened, the exhaust pipe is separated from the surface of the pressure sensor 4. At this time, the spring 2 is fully expanded and will not apply any pressure to the pressure sensor 4, so that the electrical signal disappears. The vehicle system cannot receive the signal and will issue an alarm to remind the owner that the exhaust pipe fixing position has fallen off, so that it can be discovered in time; the structure is simple, the operation is very convenient, and the labor intensity is effectively reduced.
