Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a testing device for the moving section of an automotive door wiring harness. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and finally bundled together to form a connected circuit. Therefore, the reliability of wiring harnesses is crucial, requiring extensive testing to verify product reliability.

[0003] Automotive door wiring harnesses are wiring harnesses installed at the doors of a vehicle to control related components on the door. They need to be routed from the vehicle body to the door. Because car doors need to be closed and opened during use, the section of wiring harness between the door and the vehicle body needs to move frequently with the door's opening and closing, thus requiring high reliability from this section of wiring harness. Therefore, it is necessary to test the reliability of this section of wiring harness before it leaves the factory to ensure product performance. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a testing device for the moving segment of an automotive door wiring harness.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a testing device for the moving section of an automotive door wiring harness, comprising a base, a vertical plate fixedly mounted on the base, a horizontal plate protruding from the inner side of the vertical plate, a vertical rotating shaft rotatably mounted on the horizontal plate, a connecting block fixedly mounted on the upper end of the rotating shaft, a rotating plate fixedly mounted on the connecting block, both the vertical plate and the rotating plate having wiring harness fixing holes for installing automotive door wiring harnesses, and a driving mechanism for driving the rotating shaft to rotate on the base.

[0006] By adopting the above technical solution, a vertical plate, a horizontal plate, a rotating shaft, a connecting block, and a rotating plate are set on the base. The rotating plate and the vertical plate are rotatably connected by the rotating shaft to simulate the car body and car door. Then, wire harness fixing holes are opened on the vertical plate and the rotating plate for installing the car door wire harness. In this way, the rotating shaft is driven by the drive mechanism to rotate, thereby driving the rotating plate to rotate, thus simulating the opening and closing action of the car door, and performing motion testing on the car door wire harness to ensure product performance.

[0007] Furthermore, the drive mechanism includes a fixed seat mounted on the base, the lower end of the rotating shaft passing through the horizontal plate and rotatably connected to the fixed seat, a gear being mounted on the shaft located between the fixed seat and the horizontal plate, a mounting seat being mounted on the base, a drive cylinder being mounted on the mounting seat, and a rack being fixedly mounted on the piston rod end of the drive cylinder, the rack meshing with the gear.

[0008] By adopting the above technical solution, a gear, a rack, and a drive cylinder are set up. The drive cylinder drives the rack to move laterally, which in turn drives the gear to rotate, thereby driving the shaft to rotate.

[0009] Furthermore, a bearing is provided on the fixed base, and the lower end of the rotating shaft is rotatably disposed within the bearing.

[0010] By adopting the above technical solution, a bearing is installed on the fixed base to install the rotating shaft, ensuring the flexibility of the rotating shaft's rotation.

[0011] Furthermore, the base is also provided with a connecting seat, and the connecting seat is provided with a guide slide rail. The length direction of the guide slide rail is consistent with the extension direction of the piston rod of the drive cylinder. A sliding seat is slidably disposed on the guide slide rail, and the sliding seat is fixedly connected to the rack.

[0012] By adopting the above technical solution, a connecting seat, a guide rail, and a sliding seat are set up. The sliding seat slides on the guide rail to guide the movement of the piston rod of the drive cylinder.

[0013] Furthermore, a limit ring is provided on the mounting base on the piston rod side of the drive cylinder.

[0014] By adopting the above technical solution and setting a limit ring, the retraction stroke of the piston rod of the drive cylinder is limited, thereby ensuring that the rack and gear are always in a meshing state.

[0015] Furthermore, wire harness fixing brackets are provided on the opposite sides of both the vertical plate and the rotating plate.

[0016] By adopting the above technical solution, wiring harness fixing brackets are set on the opposite sides of both the vertical plate and the rotating plate to fix the car door wiring harness.

[0017] In summary, this utility model has the following beneficial effects: In this application, by setting a vertical plate, a horizontal plate, a rotating shaft, a connecting block, and a rotating plate on the base, and rotatably connecting the rotating plate and the vertical plate via the rotating shaft, it is used to simulate the car body and car door; then, wire harness fixing holes are opened on the vertical plate and the rotating plate for installing the car door wire harness. In this way, the rotating shaft is driven to rotate by the drive mechanism, thereby driving the rotating plate to rotate, thus simulating the opening and closing action of the car door, and performing motion testing on the car door wire harness to ensure product performance.

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-2 As shown in the illustration, this application discloses a testing device for the moving segment of an automotive door wiring harness, including a base 10. The base 10 is equipped with a vertical plate 20, a horizontal plate 21, a rotating shaft 30, a connecting block 31, a rotating plate 40, and a drive mechanism 60. The vertical plate 20 is fixedly mounted on the base 10 to simulate the A-pillar or B-pillar position of the vehicle body. The horizontal plate 21 protrudes from the inner side of the vertical plate 20. The rotating shaft 30 is vertically arranged and rotatably mounted on the horizontal plate 21. The connecting block 31 is fixedly mounted on the upper end of the rotating shaft 30, and the rotating plate 40 is fixedly mounted on the connecting block 31. The rotating plate 40 simulates a car door, rotating relative to the vertical plate 20 via the rotating shaft 30. The drive mechanism 60 drives the rotating shaft 30 to rotate, thereby causing the vertical plate 20 to rotate, simulating the opening and closing action of a car door. Both the vertical plate 20 and the rotating plate 40 have wiring harness fixing holes 50 for installing the automotive door wiring harness. The two ends of the moving section of the automotive door wiring harness are respectively installed in the two wiring harness fixing holes 50. This allows the drive mechanism 60 to drive the rotating shaft 30 to rotate, simulating the opening and closing action of a car door, thereby testing the reliability of the moving section of the automotive door wiring harness in the open and closed state of the door. Wiring harness fixing brackets 70 are provided on opposite sides of the vertical plate 20 and the rotating plate 40 to fix the branch wire connectors extending from both ends of the moving section of the automotive door wiring harness.

[0023] Specifically, the drive mechanism 60 includes a fixed seat 61 mounted on the base 10, with the lower end of the rotating shaft 30 passing through the horizontal plate 21 and rotatably connected to the fixed seat 61. To ensure the flexibility of the rotating shaft 30's rotation, a bearing 66 is provided on the fixed seat 61, and the lower end of the rotating shaft 30 is rotatably mounted within the bearing 66. A gear 62 is mounted on the shaft of the rotating shaft 30 located between the fixed seat 61 and the horizontal plate 21. A mounting seat 63 is provided on the base 10, and a drive cylinder 64 is mounted on the mounting seat 63. A rack 65 is fixedly mounted on the end of the piston rod of the drive cylinder 64, and the rack 65 meshes with the gear 62. By extending or retracting the piston rod of the drive cylinder 64, the rack 65 moves horizontally, thereby driving the gear 62 to rotate, causing the rotating shaft 30 to rotate synchronously.

[0024] To ensure that rack 65 and gear 62 are always in a meshed state, a limit ring 641 is provided on the mounting base 63 on the piston rod side of drive cylinder 64. The limit ring 641 restricts the retraction stroke of piston rod of drive cylinder 64. That is, when piston rod of drive cylinder 64 is fully extended and the piston rod end is shortened and in contact with limit ring 641, rack 65 and gear 62 are always in a meshed state, thereby preventing rack 65 from falling off and affecting equipment operation.

[0025] A further configuration includes a connecting seat 67 on the base 10, with a guide rail 68 mounted on the connecting seat 67. The length direction of the guide rail 68 is aligned with the extension direction of the piston rod of the drive cylinder 64. A sliding seat 69 is slidably mounted on the guide rail 68, and the sliding seat 69 is fixedly connected to the rack 65. When the piston rod of the drive cylinder 64 extends or retracts, causing the rack 65 to move horizontally, the rack 65 will slide along the guide rail 68 with the sliding seat 69. This sliding cooperation between the sliding seat 69 and the guide rail 68 guides the extension movement of the piston rod of the drive cylinder 64, ensuring smooth movement of the piston rod.

[0026] The operating principle of the testing device for the moving section of a car door wiring harness in this embodiment is as follows: The two ends of the moving section of the car door wiring harness are respectively installed in two wiring harness fixing holes 50, and the branch lines at both ends are fixed by wiring harness fixing brackets 70, thus completing the installation of the car door wiring harness; then, the drive cylinder 64 is activated to make its piston rod reciprocate, driving the rack 65 to reciprocate horizontally, thereby driving the gear 62 to rotate back and forth, causing the rotating plate 40 to rotate back and forth around the rotating shaft 30, simulating the opening and closing action of a car door, thereby testing the reliability of the car door wiring harness. The above description is only a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
