Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, specifically a constraint device for automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses are a core component of automotive electrical systems, often referred to as the "nervous system" of a car. They consist of multiple wires, connectors, terminals, insulating sleeves, protective materials, etc. Through proper layout and connection, they transmit electrical energy, signals, and data to various electronic devices and systems in the car, ensuring the normal operation of the vehicle.

[0003] For example, patent application number 202420019323.4 published on the China Patent Network, entitled "A Bundling Device for Automotive Wiring Harnesses," includes a fixed arc plate. A fixing block is fixedly installed at the upper front end of the fixed arc plate. A first locking block is fixedly installed at the front end of the fixing block near the center of the fixed arc plate. A movable arc plate is rotatably connected to the upper rear end of the fixed arc plate via a hinge. Fixing slots are provided at both ends of the movable arc plate on the side away from the hinge. An adjusting block is movably installed in the middle of the side of the movable arc plate away from the hinge. This bundling device for automotive wiring harnesses uses rubber clips on the inner surfaces of the fixed and movable arc plates to gather the wiring harnesses together while maintaining a fixed position for fixation and limitation. This keeps the wiring harnesses neat while being bundled. Simultaneously, the cavities formed inside the fixed and movable arc plates provide space for heat dissipation during bundling, preventing high temperatures from affecting the lifespan of the wiring harnesses.

[0004] However, the existing fixing methods of the bundled devices are relatively simple, mainly relying on a large number of elastic clips for connection. During the connection process between the bundle and the clips, the clips are prone to breakage due to excessive compression. At the same time, the elasticity of the clips is prone to loss of performance after repeated compression, affecting the connection stability.

[0005] Therefore, it is necessary to redesign and modify the constraint device for automotive wiring harnesses. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a constraint device for automotive wiring harnesses, which has the advantage of improving connection stability. It solves the problem that the existing bundling devices have a relatively simple fixing method, mainly relying on a large number of elastic buckles for clamping. During the connection process between the wiring harness and the buckles, the buckles are prone to breakage due to excessive compression strength. At the same time, the elasticity of the buckles is prone to performance loss after repeated compression, affecting the connection stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a constraint device for automotive wiring harnesses, comprising an outer frame;

[0008] Connecting blocks are fixedly connected to both the front and back of the outer frame. An inner cylinder is fixedly connected to the inner side of the connecting block. There is a gap between the inner cylinder and the outer frame, which can accommodate the sliding of the wire harness. Several dividing plates are provided inside the inner cylinder. The outer ends of the dividing plates penetrate the inner cylinder and extend to the outside of the inner cylinder. The dividing plates can divide the gap between the inner cylinder and the outer frame.

[0009] As a preferred embodiment of this utility model, a bolt is provided on the outer side of the connecting block, both ends of the inner side of the dividing plate are set in an inclined shape, the inner end of the bolt passes through the connecting block and the inner cylinder in sequence and extends into the interior of the inner cylinder, the connecting block is threadedly connected to the bolt, and the outer surface of the bolt is in contact with the inner side of the dividing plate.

[0010] As a preferred embodiment of this utility model, a sleeve is fixedly connected to the outside of the connecting block, and the sleeve is fitted onto the surface of the bolt and threadedly connected to the bolt.

[0011] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the top of the outer frame, threaded holes are provided at the four corners of the mounting plate, and a Velcro component is fixedly connected to the top of the mounting plate, with an adhesive layer provided on the top of the Velcro component.

[0012] As a preferred embodiment of this utility model, the outer frame has openings on both the left and right sides, and the openings are connected to the spaces divided by the partition plate.

[0013] As a preferred embodiment of this utility model, the outer end of the dividing plate is fixedly connected to a limiting strip, and the inner surface of the inner cylinder is fixedly connected to an extension sleeve sleeved on the surface of the dividing plate, the extension sleeve being slidably connected to the dividing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model forms a wire harness accommodating space through the gap between the inner cylinder and the outer frame. The dividing plate divides the gap into multiple independent channels to avoid wire harness entanglement and realize the regional fixation of multiple wire harnesses. The rigid dividing plate replaces the traditional elastic buckle, eliminating the performance degradation problem caused by elastic fatigue and improving long-term stability.

[0016] 2. In this utility model, the bolt is pushed into the inclined end face of the inner side of the contact plate through the thread, and pushes the contact plate to slide outward, so as to realize the flexible adjustment of the channel width and adapt to different wire harness diameters.

[0017] 3. This utility model uses a sleeve to cover the surface of the bolt, preventing direct friction between the bolt and the connecting block, thus extending the service life of the bolt. The thread fit between the sleeve and the bolt enhances the connection stability and avoids repeated adjustments that could lead to thread stripping.

[0018] 4. This utility model supports standardized bolt fixing through the threaded holes at the four corners of the mounting plate, simplifying the vehicle body installation process, and the Velcro component enables multiple installation methods for the outer frame.

[0019] 5. This utility model connects the openings on the left and right sides of the outer frame with the channels formed by the partition plate, supporting the introduction of wire harnesses from both sides laterally, avoiding axial pulling damage to the wire harnesses, while improving the heat dissipation effect of the outer frame and reducing the structural weight of the outer frame.

[0020] 6. This utility model limits the sliding range of the dividing plate by the limiting strip at the outer end of the dividing plate, so as to prevent the dividing plate from completely detaching from the inner cylinder and causing structural failure. The extension sleeve wraps around the surface of the dividing plate to reduce the frictional resistance when the dividing plate moves and ensure smooth adjustment. Attached Figure Description

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.

[0027] like Figures 1 to 4 As shown, the present invention provides a constraint device for automotive wiring harnesses, including an outer frame 1;

[0028] Connecting blocks 2 are fixedly connected to both the front and back of the outer frame 1. An inner cylinder 3 is fixedly connected to the inner side of the connecting block 2. There is a gap between the inner cylinder 3 and the outer frame 1, which can accommodate the sliding of the wire harness. Several dividing plates 4 are provided inside the inner cylinder 3. The outer end of the dividing plate 4 passes through the inner cylinder 3 and extends to the outside of the inner cylinder 3. The dividing plate 4 can divide the gap between the inner cylinder 3 and the outer frame 1.

[0029] refer to Figure 3 Bolts 5 are provided on the outer side of the connecting block 2. Both ends of the inner side of the dividing plate 4 are inclined. The inner end of the bolt 5 passes through the connecting block 2 and the inner cylinder 3 in sequence and extends into the interior of the inner cylinder 3. The connecting block 2 and the bolt 5 are threadedly connected. The outer surface of the bolt 5 is in contact with the inner side of the dividing plate 4.

[0030] As a technical optimization of this utility model, the bolt 5 pushes the inclined end face of the inner side of the contact dividing plate 4 through the thread, and pushes the dividing plate 4 to slide outward, so as to realize the flexible adjustment of the channel width and adapt to different wire harness diameters.

[0031] refer to Figure 2 A sleeve 6 is fixedly connected to the outside of the connecting block 2. The sleeve 6 is fitted onto the surface of the bolt 5 and threadedly connected to the bolt 5.

[0032] As a technical optimization of this utility model, the sleeve 6 is fitted onto the surface of the bolt 5 to prevent the bolt 5 from directly rubbing against the connecting block 2, thereby extending the service life of the bolt 5. The thread fit between the sleeve 6 and the bolt 5 enhances the connection stability and avoids repeated adjustments that could lead to thread stripping.

[0033] refer to Figure 2 The top of the outer frame 1 is fixedly connected to a mounting plate 7. Threaded holes 8 are provided at the four corners of the mounting plate 7. A Velcro component 9 is fixedly connected to the top of the mounting plate 7. An adhesive layer 10 is provided on the top of the Velcro component 9.

[0034] As a technical optimization of this utility model, the standardized bolts 5 are fixed by the threaded holes 8 at the four corners of the mounting plate 7, which simplifies the vehicle body installation process, and the Velcro component 9 realizes multiple installation methods for the outer frame 1.

[0035] refer to Figure 1 The outer frame 1 has openings 11 on both the left and right sides, and the openings 11 are connected to the space divided by the partition plate 4.

[0036] As a technical optimization of this utility model, the channels formed by the openings 11 on the left and right sides of the outer frame 1 and the dividing plate 4 are connected to support the horizontal introduction of the wire harness from both sides, avoiding axial pulling damage to the wire harness, while improving the heat dissipation effect of the outer frame 1 and reducing the structural weight of the outer frame 1.

[0037] refer to Figure 4The outer end of the dividing plate 4 is fixedly connected to a limit strip 12, and the inner surface of the inner cylinder 3 is fixedly connected to an extension sleeve 13 sleeved on the surface of the dividing plate 4. The extension sleeve 13 is slidably connected to the dividing plate 4.

[0038] As a technical optimization of this utility model, the sliding range of the dividing plate 4 is limited by the limiting strip 12 at the outer end of the dividing plate 4 to prevent the dividing plate 4 from completely separating from the inner cylinder 3 and causing structural failure. The extension sleeve 13 wraps around the surface of the dividing plate 4 to reduce the frictional resistance when the dividing plate 4 moves and ensure smooth adjustment.

[0039] The working principle and usage process of this utility model are as follows: First, the device is fixed to the vehicle body at a preset position using bolts 5 through the threaded holes 8 on the top mounting plate 7 of the outer frame 1, ensuring the frame is stable. The openings 11 on the left and right sides of the outer frame 1 communicate with the space formed by the dividing plate 4, providing a channel for the lateral introduction of the wire harness. When the wire harness has been moved, the operator rotates the bolts 5 on the outside of the connecting block 2. The inner end of the bolt 5 is pushed inward due to the threaded connection, contacting the inclined end face on the inner side of the dividing plate 4, and pushing the dividing plate 4 to slide outward along the extension sleeve 13. The limiting strip 12 at the outer end of the dividing plate 4 prevents it from detaching from the inner cylinder 3, ensuring adjustment stability. The movement of the dividing plate 4 divides the gap between the inner cylinder 3 and the outer frame 1 into multiple independent channels to adapt to the independent storage needs of different wire harnesses. The wire harness is pushed into the corresponding dividing channel from the openings 11 on both sides of the outer frame 1. The isolation space formed by the dividing plate 4 can prevent the wire harness from tangling or rubbing.

[0040] In summary, this automotive wiring harness constraint device creates a wiring harness accommodating space through the gap between the inner cylinder 3 and the outer frame 1. The dividing plate 4 divides the gap into multiple independent channels, preventing the wiring harness from tangling and enabling multiple wiring harnesses to be fixed in different areas. The rigid dividing plate 4 replaces the traditional elastic buckle, eliminating the performance degradation problem caused by elastic fatigue and improving long-term stability.
