Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, and in particular to a dust cover of a brake pad wear sensor. Background Art

[0002] The brake structure plays a very important role in automobile parts, ensuring the safe driving of the car. During the braking process, the friction pad of the brake pad and the brake disc rub and roll, causing the friction pad to be gradually worn. When the friction pad is worn to a certain thickness, it reaches the scrap standard, and the brake pad needs to be replaced. When replacing the brake pad, the entire brake pad is generally replaced, including the sensor used to detect the degree of wear of the friction pad. However, general sensors have long wiring harnesses, which can be damaged during transportation, causing the brake pad to fail. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a brake pad wear sensor with a dust cover that is easy to transport.

[0004] The purpose of the present invention can be achieved through the following technical solutions: a brake pad wear sensor with a dust cover, the sensor includes a sensor line, a plug and a plug, the middle part of the sensor line is sleeved on the plug, and the plug is provided with a detachable dust cover; the middle part of the sensor line is inserted into the friction plate of the brake pad through the plug, and during transportation, the plug is fixed to the brake pad through the dust cover. The present invention provides a detachable dust cover, which can prevent dust and other impurities from being introduced into the plug during transportation, and at the same time enhance the strength of the plug; on the other hand, the dust cover can be fixed on the brake pad, so that the plug can be relatively fixed during transportation, ensuring that the entire brake pad is relatively fixed during transportation, reducing the possibility of damage.

[0005] The plug comprises a plug-in portion and a protective cover fixed on the outer periphery of the plug-in portion, and a connecting hole is arranged on the side of the protective cover.

[0006] The dust cover includes a flat plate and a connecting part arranged at one end of the upper side of the flat plate, the connecting part matches the shape of the inner wall of the protective cover, and the side of the connecting part is provided with a buckle arranged outward, and the buckle matches the connecting hole. Through this arrangement, the connecting part and the protective cover can be fixed, and the disassembly and assembly are convenient, as follows: insert the connecting part inward along the inner wall of the protective cover until the buckle contacts the opening of the protective cover, and continue to insert it inward. Since the material of the dust cover is plastic, the buckle will be gradually flattened. When the connecting part is inserted into the bottom of the protective cover, the buckle just moves to the position of the connecting hole, and the buckle loses the pressure from the upper part and returns to its original state, so that it is stuck by the connecting hole, and the connecting part and the protective cover are fixed. When installation is required, manually press the buckle down, and then pull the connecting part out of the protective cover.

[0007] The other end of the plate has two semicircular claws that are oppositely arranged, the front ends of the two claws are separated, and the distance between the front ends of the two claws is less than the thickness of the brake pad, and the rear ends of the two claws are integrated with the plate. Since the dust cover is made of plastic, the above arrangement can make the plate tightly clamped on the brake pad.

[0008] The central side of the plate is symmetrically provided with wave-shaped placement grooves, and the width of each placement groove matches the diameter of the sensor line. The placement grooves can be arranged so that the sensor line can be wound on the plate during transportation, further reducing the volume of the entire brake pad and reducing the possibility of damage.

[0009] The latch is T-shaped, including a clamping part and a latch head integrally arranged in the middle of the clamping part. The clamping part is I-shaped, and has clamping grooves for clamping the sensor wire on both sides. The latch head has grooves for placing the sensor wire on both sides. The grooves and the clamping grooves are located in the same plane. The middle part of the sensor wire is clamped in the clamping grooves and the grooves to form a U-shaped bend. The middle part of the sensor wire is bent into a U-shape by the latch. On the one hand, the sensor wire is easily fixed so that it will not slip when worn; on the other hand, the sensor wire is inserted into the friction plate together with the latch, which makes installation more convenient.

[0010] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0011] (1) The sensor wire is inserted into the friction plate of the brake pad through a plug, and the plug is fixed to the brake pad through a dust cover. The sensor wire can also be wound around the dust cover, so that the entire brake pad requires less space during transportation, reducing the possibility of damage to the brake pad;

[0012] (2) The dust cover and plug are easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0019] Example 1

[0020] A brake pad wear sensor with a dust cover, the structure of which is as follows Figure 1 The invention comprises a sensor line 2, a plug 1 and a plug 4. The middle part of the sensor line 2 is sleeved on the plug 4, and the plug 1 is provided with a detachable dust cover 3. The middle part of the sensor line 2 is inserted into the friction plate of the brake pad through the plug 4. During transportation, the plug 1 is fixed to the brake pad through the dust cover 3. The present invention provides a detachable dust cover 3, which can prevent dust and other impurities from being introduced into the plug 1 during transportation and enhance the strength of the plug 1. On the other hand, the dust cover 3 can be fixed on the brake pad, so that the plug 1 can be relatively fixed during transportation, ensuring that the entire brake pad is relatively fixed during transportation and reducing the possibility of damage.

[0021] The structure of plug 1 is as follows Figure 2 As shown, it includes a plug-in portion 11 and a protective cover 12 fixed to the outer periphery of the plug-in portion 11, and a connecting hole 13 is provided on the side of the protective cover 12. An insulating sleeve 21 is provided on the outer side of the sensing line 2 to prevent the sensing line 2 from changing in resistance due to dust or other reasons.

[0022] The structure of the dust cover 3 is as follows Figure 3As shown, it includes a flat plate 32 and a connecting portion 31 arranged at one end of the upper side of the flat plate 32. The connecting portion 31 matches the shape of the inner wall of the protective cover 12. The side of the connecting portion 31 is provided with a buckle 33 arranged outward, and the buckle 33 matches the connecting hole 13. Through this arrangement, the connecting portion 31 and the protective cover 12 can be fixed, and the disassembly and assembly are convenient, as follows: insert the connecting portion 31 inward along the inner wall of the protective cover 12 until the buckle 33 contacts the opening of the protective cover 12, and continue to insert it inward. Since the material of the dust cover 3 is plastic, the buckle 33 will be gradually flattened. When the connecting portion 31 is inserted into the bottom of the protective cover 12, the buckle 33 just moves to the position of the connecting hole 13, and the buckle 33 loses the pressure from the upper part and returns to its original state, so that it is clamped by the connecting hole 13, and the connecting portion 31 and the protective cover 12 are fixed. When installation is required, the buckle 33 is manually pressed down, and then the connecting portion 31 is pulled out of the protective cover 12.

[0023] The other end of the flat plate 32 has two semicircular claws 34 that are arranged opposite to each other. The front ends of the two claws 34 are separated, and the distance between the front ends of the two claws 34 is less than the thickness of the brake pad. The rear ends of the two claws are integrated with the flat plate 32. Since the dust cover 3 is made of plastic, the above arrangement allows the flat plate 32 to be tightly clamped on the brake pad. Wave-shaped placement grooves 35 are symmetrically arranged on the sides of the middle part of the flat plate 32, and the width of each placement groove 35 matches the diameter of the sensor line 2. The placement grooves 35 can be arranged so that the sensor line 2 can be wound around the flat plate 32 during transportation, further reducing the volume of the entire brake pad and reducing the possibility of damage.

[0024] The structure of the latch 4 is as follows Figure 4 As shown, it is T-shaped, including a clamping part 41 and a plug head 42 integrally arranged in the middle of the clamping part 41.
