Description

Technical Field

[0001] This utility model relates to the field of electrical control wiring harness fixing technology, specifically to an integrated fixing bracket device for engine electrical control wiring harnesses. Background Technology

[0002] Engine electronic control wiring harnesses are a critical part of vehicle electrical systems, generally consisting of a main harness and multiple branch harnesses. The main harness is equipped with a main sleeve, and the roots of the branch harnesses are connected to the main harness, with connectors at their ends. The branch harnesses are also protected by sleeves. These sleeves isolate the harnesses from the external environment, protecting them from damage caused by high temperatures, oil, or corrosion. Existing patent CN206918396U discloses an integrated bracket for fixing automotive wiring harnesses, which is installed on an automotive transmission. It includes a mounting body with a first bracket and a second bracket extending from it. The mounting body has mounting holes through which the harness is installed at a predetermined position on the transmission. The first bracket has a first limiting hole, and the second bracket has a second limiting hole. This utility model discloses an integrated bracket for fixing automotive wiring harnesses, which can fix multiple different pipelines in the engine compartment and effectively separate them, avoiding interference.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In practical applications, the engine will vibrate during operation. If a simple positioning structure is used to position and tighten it, the threaded parts will loosen after long-term use, resulting in the bracket device not being firmly fixed to the wiring harness. This leads to the wiring harness becoming loose, which in turn affects the engine during operation. Therefore, we propose an integrated fixing bracket device for engine electronic control wiring harnesses to solve the above-mentioned problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: an integrated fixing bracket device for engine electronic control wiring harness, including a base 1, a snap-fit ​​limiting component 2 provided on one side of the upper surface of the base 1, an adjustment positioning component 3 provided inside the base 1, and an anti-loosening component 4 provided on the base 1.

[0030] The snap-fit ​​limiting assembly 2 includes a snap-fit ​​plate 200 fixedly installed on the base 1, and a snap-fit ​​limiting groove is provided on one side of the snap-fit ​​plate 200.

[0031] The locking and limiting component 2 facilitates the positioning and installation of the bracket during use, ensuring the stability of the bracket installation and preventing the bracket from becoming loose.

[0032] The adjusting positioning component 3 includes a cavity inside the base 1. A slide plate 300 is slidably connected inside the cavity. Slide rods 301 are fixedly installed on both sides of the slide plate 300. One end of the slide rod 301 passes through the base 1 and extends to the outside of the base 1. A threaded rod 302 is inserted into the slide plate 300. One end of the threaded rod 302 passes through the base 1 and extends to the outside of the base 1. A vertical rod 303 is fixedly installed on one end of the slide rod 301. A limiting groove is formed at the top of the vertical rod 303. A limiting block 304 is slidably connected inside the limiting groove. A return spring 305 is fixedly installed at the bottom of the limiting block 304. The bottom of the return spring 305 is fixedly connected to the inner bottom wall of the limiting groove. The two limiting blocks 304 are fixedly connected by a pressure plate 306. An arc-shaped clamping plate 307 is fixedly installed on one side of the pressure plate 306.

[0033] The anti-loosening component 4 includes a ratchet 400 fixedly mounted on the threaded rod 302, a pull rod 401 inserted into the base 1, an arc plate 402 fixedly mounted on the bottom of the pull rod 401, the arc plate 402 being engaged in the groove of the ratchet 400, and a reciprocating spring 403 surrounding the surface of the pull rod 401.

[0034] By using the adjustable positioning component 3 and the anti-loosening component 4 together, the wiring harness can be clamped and positioned during use, thereby preventing the wiring harness from loosening after long-term use due to vibration, maintaining the stability of the wiring harness connection, and preventing the loose wiring harness from affecting the engine during operation.

[0035] See Figure 1 Both sides of the top of the snap-fit ​​plate 200 are fitted with screws 201. A rotating block is fixedly installed on the top of the screw 201. A wrench is fixedly installed on the surface of the rotating block. The surface of the wrench has anti-slip texture. The screws 201 can be rotated to abut against the positioning parts in the snap-fit ​​groove on the snap-fit ​​plate 200, which facilitates the overall installation of the bracket. At the same time, the rotating block and the wrench can be rotated to easily tighten and loosen the screws 201, so that the bracket can be positioned and installed without the use of tools.

[0036] See Figure 1 The snap-fit ​​plate 200 has a screw hole for the screw 201 to pass through, and the screw hole is threadedly connected to the screw 201. An anti-slip ring 202 is fitted on the surface of the screw 201. The bottom of the anti-slip ring 202 is in contact with the top of the snap-fit ​​plate 200, and the top of the anti-slip ring 202 is in contact with the bottom of the rotating block. The anti-slip ring 202 can prevent the screw 201 from loosening during use and maintain the stability of the screw 201 tightening.

[0037] See Figure 3 and Figure 4Both sides of the base 1 are provided with rod grooves for the slide rod 301 to pass through, and the inner wall of the rod groove is slidably connected to the surface of the slide rod 301. One side of the vertical rod 303 is attached to one side of the base 1, and a limiting groove is provided on one side of the vertical rod 303 for the limiting block 304 to slide. The rod groove can limit the slide rod 301 during the movement of the slide rod 301, and also prevent it from shaking during the movement, so as to keep the slide rod 301 moving in a straight and stable manner.

[0038] See Figure 3 The slide plate 300 has a threaded hole for the threaded rod 302 to pass through, and the threaded hole is threadedly connected to the threaded rod 302. One end of the threaded rod 302 is fitted with a sleeve that is rotatably connected to the threaded rod 302. One end of the sleeve is fixedly connected to one side of the inner wall of the cavity. One side of the base 1 has a round hole for the threaded rod 302 to pass through, and the inner wall of the round hole is rotatably connected to the surface of the threaded rod 302. The sleeve can limit one end of the threaded rod 302 during use, thereby preventing the threaded rod 302 from shaking during rotation and maintaining the stability of the rotation of the threaded rod 302.

[0039] See Figure 2 and Figure 3 A rotating block is fixedly installed at one end of the threaded rod 302 outside the base 1. A hexagonal hole is opened on one side of the rotating block, and anti-slip texture is opened on the surface of the rotating block. The rotating block can rotate the threaded rod 302 during use, which is convenient for the operator.

[0040] See Figure 5 The top of the reciprocating spring 403 is fixedly connected to the inner top wall of the cavity of the base 1, and the bottom of the reciprocating spring 403 is fixedly connected to the upper surface of the arc plate 402. The top of the pull rod 401 is fixedly installed with a pull hole, and the base 1 is provided with a rod hole for the pull rod 401 to pass through. The reciprocating spring 403 can reset the arc plate 402 during use, keeping the arc plate 402 always in contact with the surface of the ratchet 400, and preventing the ratchet 400 from rotating in the opposite direction after being subjected to external force during use.

[0041] During operation, the snap-fit ​​slot on the snap-fit ​​plate 200 is snapped into the position that needs to be fixed, and then the screw 201 is tightened. The bottom of the screw 201 abuts against one side of the fixing component, thereby maintaining the installation stability of the snap-fit ​​plate 200 and the overall installation stability of the bracket device.

[0042] When it is necessary to limit and fix the wire harness, pull the lever 401 to separate the arc plate 402 on the lever 401 from the surface of the ratchet 400. Then, rotate the threaded rod 302 clockwise. The threaded rod 302 drives the slide bar 301 and the vertical bar 303 on the slide plate 300 to move to the left, thereby separating the arc-shaped clamping plate 307 from one side of the clamping plate 200. Then, place the wire harness through the gap between the arc-shaped clamping plate 307 and the clamping plate 200 into the curvature of the arc-shaped clamping plate 307. Then, rotate the threaded rod 302 in the opposite direction. The threaded rod 302 drives the slide bar 301 on the slide plate 300 to move, thereby causing the pressure plate 306 on the vertical bar 303 and the arc-shaped clamping plate 307 to move. Moving to the right, one side of the arc-shaped clamping plate 307 fits against one side of the clamping plate 200. During this process, the wire harness is prevented from detaching from the bracket. At the same time, the return spring 305 resets the pressure plate 306 on the limit block 304, causing the arc-shaped clamping plate 307 to press downwards and compress the wire harness. When the pull rod 401 is not under force, the reciprocating spring 403 resets the arc-shaped plate 402 on the pull rod 401, causing the arc-shaped plate 402 to fit against the surface of the ratchet 400. This prevents the threaded rod 302 on the ratchet 400 from rotating clockwise, thus preventing the threaded rod 302 from rotating and causing the slide bar 301 on the slide plate 300 to move to the left, thereby preventing the parts from becoming loose during use.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
