Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a rear oxygen sensor wiring harness fixing bracket. Background Technology

[0002] To meet emission regulations, most modern cars are equipped with a rear oxygen sensor. Located after the three-way catalytic converter, the rear oxygen sensor detects the oxygen content in the exhaust gas to enable closed-loop control of the air-fuel mixture. The rear oxygen sensor signal needs to be connected to the Engine Management System (EMS), and the signal harness must pass through the transmission and firewall to reach the engine compartment.

[0003] Currently, the rear oxygen sensor bracket has a single function, is inconvenient to install, and has poor clamping effect on the wiring harness, resulting in large gaps between the wiring harnesses. This can easily cause excessive friction between the wiring harnesses and damage to the wiring harness sheath. Utility Model Content

[0004] The purpose of this utility model is to provide a mounting bracket for the rear oxygen sensor harness to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A rear oxygen sensor wiring harness fixing bracket includes a middle plate, both ends of which are rotatably connected to mounting plates. A vertical plate is provided on one side of the upper surface of the middle plate, and a movable plate is provided on the other side of the upper surface of the middle plate, which is distributed opposite to the vertical plate and can reciprocate along the length of the middle plate. A screw is fixedly installed at the top of the movable plate on one side of the vertical plate, and the end of the screw passes through the vertical plate and is threaded with a nut. A lower fixing block is provided on one side of the bottom of the movable plate, and an upper fixing block is provided on the side wall of the movable plate below the screw.

[0006] Preferably, one end of the mounting plate is provided with a U-shaped opening, the size of which matches the size of the end of the intermediate plate, and both ends of the intermediate plate are rotatably connected to the U-shaped opening via connecting shafts.

[0007] Preferably, the upper surface of the mounting plate away from the U-shaped opening is provided with mounting holes.

[0008] Preferably, the top sidewall of the upright plate is provided with through holes corresponding to the screw, and the diameter of the through holes is equal to the diameter of the screw.

[0009] Preferably, the movable plate forms an inverted "F" shape with the lower and upper fixed blocks, and a fixing opening is formed between the lower and upper fixed blocks.

[0010] Preferably, a limiting opening is provided in the middle part of the upper surface of the intermediate plate along its length direction, and a limiting block is provided in the middle part of the bottom of the movable plate, which is distributed corresponding to the limiting opening, and the limiting block is slidably connected to the limiting opening.

[0011] The rear oxygen sensor wiring harness fixing bracket of this utility model has the following advantages:

[0012] 1. Because the middle plate is rotatably connected to the two mounting plates, the angle of the middle plate and the mounting plates can be easily adjusted according to the installation environment and requirements, thereby reducing the requirements for the installation position and making the installation more convenient.

[0013] 2. This utility model can clamp and fix the rear oxygen sensor wiring harness by cooperating with the movable plate, the fixing port and the upright plate, so that the wiring harness is firmly inside the fixing port, reducing the gap between the wiring harnesses, thereby effectively reducing the problem of friction between the wiring harnesses and damage to the wiring harness skin.

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a rear oxygen sensor harness fixing bracket according to this utility model.

[0025] like Figure 1-3As shown, this utility model discloses a rear oxygen sensor wiring harness fixing bracket, including a middle plate 2. Mounting plates 1 are rotatably connected to both ends of the middle plate 2. One end of the mounting plate 1 has a U-shaped opening 3, the size of which matches the size of the end of the middle plate 2. Both ends of the middle plate 2 are rotatably connected to the U-shaped opening 3 via connecting shafts 4. The cooperation between the U-shaped opening 3 and the middle plate 2 increases the friction between the middle plate 2 and the mounting plates 1, thus providing damping for the rotation of the middle plate 2 and the mounting plates 1. Furthermore, the rotatable connection between the middle plate 2 and the two mounting plates 1 facilitates adjustment of the angles of the middle plate 2 and the mounting plates 1 according to the installation environment and requirements, thereby reducing the requirements for the installation position and making installation more convenient. Mounting holes 5 are provided on the upper surface of the mounting plate 1 at the end away from the U-shaped opening 3, allowing for easy fixing of the mounting plate 1 with screws.

[0026] A vertical plate 6 is provided on one side of the upper surface of the intermediate plate 2, and a movable plate 7 is provided on the other side of the upper surface of the intermediate plate 2, which is opposite to the vertical plate 6 and can reciprocate along the length of the intermediate plate 2. A screw 8 is fixedly installed on the top of the movable plate 7 on one side of the vertical plate 6. The end of the screw 8 passes through the vertical plate 6 and is threaded with a nut 9. The top side wall of the vertical plate 6 is provided with through holes 15 corresponding to the screw 8. The diameter of the through holes 15 is equal to the diameter of the screw 8. The through holes 15 allow the end of the screw 8 to pass through the vertical plate 6. When the rear oxygen sensor wiring harness is placed into the fixing port 12, the movable plate 7 is pushed, causing the movable plate 7 to move closer to the vertical plate 6. This causes the movable plate 7 to move the wiring harness closer to the vertical plate 6, so that the wiring harness contacts the side wall of the vertical plate 6. Finally, the nut 9 is tightened, so that the movable plate 7 and the vertical plate 6 clamp and fix the wiring harness, making the wiring harness firmly inside the fixing port 12. The installation is simple and convenient.

[0027] A lower fixing block 11 is provided on one side of the bottom of the movable plate 7, and an upper fixing block 10 is provided on the side wall of the movable plate 7 below the screw 8. The movable plate 7, the lower fixing block 11, and the upper fixing block 10 form an inverted "F" shape structure, and a fixing opening 12 is formed between the lower fixing block 11 and the upper fixing block 10, so that the rear oxygen sensor wiring harness is placed in the fixing opening 12 during installation, which plays a good role in limiting the rear oxygen sensor wiring harness. A limiting opening 14 is provided in the middle part of the upper surface of the intermediate plate 2 along its length direction. A limiting block 13 is provided in the middle part of the bottom of the movable plate 7, which is distributed corresponding to the limiting opening 14. The limiting block 13 is slidably connected to the limiting opening 14. Through the cooperation between the limiting block 13 and the limiting opening 14, the movable plate 7 plays a good limiting role, so that during the tightening of the nut 9, the movable plate 7 can move closer to the vertical plate 6 along the length direction of the intermediate plate 2, thereby cooperating with the vertical plate 6 to clamp and fix the rear oxygen sensor wiring harness, reducing the gap between the wiring harnesses, and thus effectively reducing the problem of friction between the wiring harnesses and damage to the wiring harness skin.

[0028] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
