Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness fixing technology, and more specifically to a wiring harness fixing device for automotive production. Background Technology

[0002] The modernization of the automotive industry increasingly emphasizes the reliability, safety, and intelligence of vehicles. As the power and control nerve center of a vehicle, the stability of the vehicle's electrical system directly determines the overall vehicle performance. In the complex operating environment of a vehicle, wiring harnesses, as the carrier of the electrical system, undertake the critical tasks of signal transmission and power delivery. With the continuous improvement of automotive electronics, the number and types of on-board wiring harnesses have increased significantly, and their arrangement has become increasingly complex, placing higher demands on fixing and protection technologies.

[0003] In the technical field of automotive wiring harness fixing devices, traditional fixing structures are typically designed for wiring harnesses of a specific diameter or number, lacking flexibility. For example, utility model patent CN222136673U discloses an integrated fixing structure for two wiring harnesses, which uses a combination of plastic plugs and rubber sleeves to fix two wiring harnesses. Although the structure is relatively simple and reduces costs, its limiting channel is mainly suitable for a fixed number of wiring harnesses (such as two), making it difficult to flexibly adapt to significant changes in wiring harness diameter or scenarios where the number of wiring harnesses needs to be dynamically added or removed after the wiring harness layout is completed. In practical applications, if it is necessary to add or remove wiring harnesses, or if the wiring harness diameter exceeds the preset range, it is often necessary to disassemble or replace the entire fixing structure. This not only increases the complexity and time cost of maintenance, but may also lead to a decrease in the reliability or damage of the fixing structure due to repeated disassembly. Therefore, we propose a wiring harness fixing device for automotive production. Summary of the Invention

[0004] In view of this, the present invention provides a wiring harness fixing device for automobile production, which aims to solve the above-mentioned technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A wiring harness fixing device for automobile production includes a mounting frame and a fixing plate. The mounting frame is provided with an adjusting belt and an adjusting mechanism for adjusting the tension of the adjusting belt. The adjusting mechanism includes a winding rod rotatably mounted on the left side of the mounting frame. The left end of the adjusting belt is wound around the winding rod, and a locking rod is fixedly mounted on the right end of the adjusting belt. A retaining ring is fixedly mounted on the right side of the mounting frame, and the locking rod and the retaining ring are movably engaged.

[0006] In some embodiments, both ends of the winding rod pass through the mounting frame and are rotatably connected to the mounting frame via rolling bearings. Both ends of the winding rod are fitted with disc springs, and the inner and outer ends of the two sets of disc springs are fixedly connected to the winding rod and the mounting frame, respectively.

[0007] In some embodiments, a positioning sleeve is fixedly installed on the mounting bracket, the upper end of the winding rod passes through the positioning sleeve and is rotatably connected to the positioning sleeve, and four sets of symmetrically distributed rubber locking blocks are fixedly installed on the positioning sleeve, with all four sets of rubber locking blocks being fitted against the winding rod.

[0008] In some embodiments, the positioning sleeve is threaded with a tapered locking sleeve, and the tapered locking sleeve is movably engaged with a rubber locking block.

[0009] In some embodiments, the fixed plate is provided with a vibration damping protection mechanism, which includes a mounting plate fixedly bonded to the mounting bracket. Two sets of cross-distributed brackets are provided between the mounting plate and the fixed plate. The right ends of the two sets of brackets are rotatably mounted on the mounting plate via a rotating shaft, and the left ends of the two sets of brackets are rotatably mounted with sliders. A sliding rod is fixedly installed inside the fixed plate.

[0010] In some embodiments, the slider is slidably connected to the fixed plate, and a damper is fixedly installed between the slider and the fixed plate, with a first spring fitted on the damper.

[0011] In some embodiments, the slider is slidably sleeved with the slide rod, and two sets of symmetrically distributed second springs are sleeved on the slide rod, with the two ends of the two sets of second springs respectively fixedly connected to the slider and the fixing plate.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a wiring harness fixing device for automobile production, which has the following beneficial effects: 1. This invention effectively solves the problem of poor adaptability of traditional fixing structures by setting an adjustable wire harness fixing device. The device adopts a design combining an adjusting belt and an adjusting mechanism. Users can flexibly adjust the length and tension of the adjusting belt by operating the winding rod, thereby adapting to wire harness groups of different diameters or numbers. The quick-release structure of the locking rod and locking ring further simplifies the installation and disassembly process, significantly improving the ease of operation. In addition, the configuration of the coil spring ensures that the adjusting belt remains taut in its natural state, avoiding loosening due to vibration and enhancing the reliability of the fixation. After adjusting the extension length of the adjusting belt, rotating the conical locking sleeve downwards simultaneously squeezes four sets of rubber locking blocks to fix the winding rod, preventing the wire harness fixation from loosening due to the loosening of the adjusting belt during use.

[0013] 2. This invention, through the synergistic action of cross brackets, sliders, dampers, and multiple sets of springs, effectively buffers and absorbs vibrations and impacts from external equipment, robotic arms, or conveyor systems during wire harness installation and production transfer, preventing wear or displacement of the wire harness due to vibrations and collisions during production. This design not only improves the safety and stability of the wire harness during production assembly but also ensures the reliable application of the fixing device in dynamic production environments, demonstrating strong practicality and wide applicability.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: Please see Figure 1-3This invention provides a technical solution: a wire harness fixing device for automobile production, comprising a mounting frame 1 and a fixing plate 3, characterized in that: the mounting frame 1 is provided with an adjusting band 2, and the mounting frame 1 is provided with an adjusting mechanism 4 for adjusting the tension of the adjusting band 2. The adjusting mechanism 4 includes a winding rod 401 rotatably mounted on the left side of the mounting frame 1, the left end of the adjusting band 2 is wound around the winding rod 401, the right end of the adjusting band 2 is fixedly mounted with a locking rod 403, and the right side of the mounting frame 1 is fixedly mounted with a retaining ring 404, the locking rod 403 and the retaining ring 404 being movably engaged. This wire harness fixing device achieves flexible adaptation to different wire harness sizes through the adjusting mechanism 4. The user inserts the locking rod 403 at the right end of the adjusting band 2 into the retaining ring 404 on the right side of the mounting frame 1 to complete the initial fixing, and then rotates the winding rod 401 to wind or release the adjusting band 2, thereby adjusting its effective length and tension to adapt to wire harnesses of different diameters or numbers.

[0019] Both ends of the winding rod 401 pass through the mounting frame 1 and are rotatably connected to the mounting frame 1 via rolling bearings. Both ends of the winding rod 401 are fitted with disc springs 402. The inner and outer ends of the two sets of disc springs 402 are fixedly connected to the winding rod 401 and the mounting frame 1, respectively. The disc springs 402 always provide a reverse torque to the winding rod 401, so that the adjusting belt 2 remains taut in its natural state, effectively preventing loosening caused by slight vibration.

[0020] A positioning sleeve 405 is fixedly installed on the mounting bracket 1. The upper end of the winding rod 401 passes through the positioning sleeve 405 and is rotatably connected to the positioning sleeve 405. Four sets of symmetrically distributed rubber locking blocks 406 are fixedly installed on the positioning sleeve 405. All four sets of rubber locking blocks 406 are fitted against the winding rod 401. A conical locking sleeve 407 is threaded onto the positioning sleeve 405. The conical locking sleeve 407 is movably engaged with the rubber locking blocks 406. After adjustment, tightening the conical locking sleeve 407 downwards can simultaneously squeeze the four sets of rubber locking blocks 406, making them tightly hug the winding rod 401 to achieve mechanical locking. This completely eliminates the problem of the adjustment belt 2 loosening due to the rotation of the winding rod 401 during use, ensuring that the wire harness is continuously and reliably fixed.

[0021] Example 2: Please see Figure 4 , Figure 5The fixed plate 3 is equipped with a vibration damping protection mechanism 5. The vibration damping protection mechanism 5 includes a mounting plate 501 fixedly bonded to the mounting frame 1. There are two sets of cross-distributed brackets 502 between the mounting plate 501 and the fixed plate 3. The right ends of the two sets of brackets 502 are rotatably mounted on the mounting plate 501 through a rotating shaft. The left ends of the two sets of brackets 502 are rotatably mounted with sliders 503. A sliding rod 506 is fixedly installed inside the fixed plate 3. The slider 503 is slidably connected to the fixed plate 3. A damper 504 is fixedly installed between the slider 503 and the fixed plate 3. A first spring 505 is fitted on the damper 504. The slider 503 is slidably sleeved with the sliding rod 506. Two sets of symmetrically distributed second springs 507 are sleeved on the sliding rod 506. The two ends of the two sets of second springs 507 are fixedly connected to the slider 503 and the fixed plate 3, respectively. The vibration damping protection mechanism 5 of this device plays a key role in the production process. When the mounting frame 1 is subjected to external vibration or impact from production equipment, robotic arms, or conveying systems, the force is transmitted through the mounting plate 501 to two sets of cross-distributed supports 502. The supports 502 push the slider 503 to slide along the slide bar 506. During this process, the damper 504 and the first spring 505 work together to absorb and dissipate energy, while the second springs 507 symmetrically distributed on the slide bar 506 further buffer the vibration, jointly transforming the instantaneous impact into a gentle reciprocating motion. This greatly reduces the amplitude and acceleration transmitted to the wire harness, thereby effectively preventing wear, displacement, or damage to the wire harness caused by vibration and collision during production, handling, and installation.
