Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing technology, and in particular to a millimeter-wave radar wire harness wiring fixing device. Background Technology

[0002] In the fields of intelligent driving and industrial automation, millimeter-wave radar harness fixing faces problems such as insufficient compatibility with traditional technologies, poor shock resistance, and cumbersome installation and maintenance. For example, the need for multiple models to adapt to a single specification slot leads to high costs, rigid connections are prone to harness wear and loosening, and the reliance on tools results in low efficiency. It is difficult to effectively solve the existing technical bottlenecks and meet the high reliability and efficient maintenance requirements of harness fixing in complex environments such as vehicles and industries.

[0003] However, existing millimeter-wave radar harness wiring fixers have the following drawbacks:

[0004] (1) In autonomous vehicles, a single millimeter-wave radar may need to connect 5-8 wire harnesses of different specifications at the same time. Traditional fasteners are difficult to be compatible with wire harnesses of different diameters, which can easily lead to wire harness tangling, mutual interference, or even signal attenuation due to compression.

[0005] (2) Traditional fasteners usually require tools such as screwdrivers and wrenches for fixing, which makes it difficult to operate in narrow spaces such as car chassis and dashboard.

[0006] Therefore, this utility model provides a millimeter-wave radar harness wiring fixer. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical millimeter-wave radar wiring harness fixing device, which solves the problems mentioned in the background art of traditional fixing devices being difficult to be compatible with wiring harnesses of different diameters and difficult to operate in confined spaces such as car chassis and dashboards.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a millimeter-wave radar harness wiring fixer, comprising a lower clamping plate, an upper clamping plate rotatably connected to one side of the top of the lower clamping plate, multiple rectangular slots being provided on the opposite side of the lower clamping plate and the upper clamping plate, a U-shaped plate being provided on the inner sidewall of each rectangular slot, an installation groove being provided on the inner top wall of the rectangular slot, a connecting component being provided inside the installation groove, and a fixing component being provided between the lower clamping plate and the upper clamping plate;

[0011] The connecting assembly includes a cylindrical clip fixedly connected to the top of the U-shaped plate, an installation rod installed on the inner top wall of the mounting groove, and arc-shaped clamps adapted to the cylindrical clips rotatably connected to both sides of the bottom of the installation rod. A connecting block is fixedly connected to one side of the arc-shaped clamps, and a compression spring is connected between the top of the connecting block and the inner top wall of the mounting groove.

[0012] The fixing assembly includes a mounting block fixedly connected to the other side of the lower clamping plate. The mounting block has a cavity inside. A telescopic rod is movably connected to the inner wall of the cavity. A tension spring is connected between the bottom of the telescopic rod and the inner bottom wall of the cavity. A sector plate is fixedly connected to the top of the telescopic rod. A plug rod is fixedly connected to the bottom of the sector plate. A slot that matches the plug rod is provided on the other side of the top of the upper clamping plate.

[0013] Optionally, each of the U-shaped plates is equipped with a clamping block adapted to wire harnesses of different diameters. The clamping block is made of rubber, which allows it to fit tightly to wire harnesses of different diameters through deformation, thus avoiding insecure fixing or damage due to wire harness diameter deviation.

[0014] Optionally, a fixing seat is fixedly connected to the top of the upper clamping plate, and a nameplate is provided on the top of the fixing seat. Screws are provided at the four corners of the nameplate. The nameplate can mark the function, specifications or installation date of the wiring harness, so that it is not necessary to check each one during maintenance.

[0015] Optionally, a limiting ring is fitted onto the surface of the telescopic rod, and a limiting groove adapted to the limiting ring is provided on the inner side wall of the cavity. The limiting ring prevents the rod from being pulled out excessively, causing fixation failure, or from being pressed in excessively, damaging the upper clamp slot.

[0016] Optionally, a rubber pad is fixedly connected to the side opposite to the upper clamping plate of the lower clamping plate. The surface of the rubber pad is provided with V-shaped anti-slip texture. The rubber pad can absorb the impact force when the clamping plates are closed, avoid the wire harness skin indentation caused by rigid contact, and protect the precision wire harness.

[0017] Optionally, the bottom of the lower clamp is fixedly connected to a mounting base, and the top of the mounting base is provided with multiple countersunk holes. The countersunk hole design makes the head of the mounting screw flush with the surface of the mounting base, avoiding the protruding part from scratching the wire harness or other components.

[0018] (III) Beneficial Effects

[0019] This utility model provides a millimeter-wave radar harness wiring fixer, which has the following advantages:

[0020] 1. This millimeter-wave radar wiring harness fixing device allows for compatibility with wiring harnesses of different diameters by replacing the clamps and connecting components. This reduces the types of fixing devices used in vehicle development, lowers mold costs and inventory pressure. At the same time, wiring harnesses with different functions, such as power lines, signal lines and grounding lines, can be fixed in different sections by different clamps, facilitating quick identification and repair during later maintenance and improving after-sales efficiency.

[0021] 2. The millimeter-wave radar harness wiring fixture uses a "plug-in" locking mechanism between the fan-shaped plate and the plug rod. When the upper clamp rotates around the rotating shaft to a near-closed position, the inclined surface of the fan-shaped plate contacts the inner wall of the mounting block, automatically guiding the plug rod to align with the slot without manual alignment. After releasing the handle, the tension spring returns to its original position, and the plug rod quickly snaps into the slot, completing the locking process. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a millimeter-wave radar harness wiring fixer, including a lower clamping plate 1, an upper clamping plate 101 rotatably connected to one side of the top of the lower clamping plate 1, multiple rectangular slots are provided on the opposite side of the lower clamping plate 1 and the upper clamping plate 101, a U-shaped plate 102 is provided on the inner side wall of each rectangular slot, an installation slot is provided on the inner top wall of the rectangular slot, a connecting component 2 is provided inside the installation slot, and a fixing component 3 is provided between the lower clamping plate 1 and the upper clamping plate 101;

[0029] The connecting component 2 includes a cylindrical clamping block 201 fixedly connected to the top of the U-shaped plate 102. An installation rod 202 is installed on the inner top wall of the mounting groove. Both sides of the bottom of the installation rod 202 are rotatably connected to arc-shaped clamping plates 203 that are adapted to the cylindrical clamping block 201. The inner arc surface is in contact with the cylindrical clamping block 201, and the outer side is linked to the compression spring 205 through the connecting block 204. The connecting block 204 is fixedly connected to one side of the arc-shaped clamping plate 203. The top of the connecting block 204 and the inner top wall of the mounting groove are connected together by the compression spring 205, which provides a downward elastic force to ensure that the U-shaped plate 102 and the clamping plate are in close contact. The compression spring 205 has an elastic coefficient of k1 = 5 N / mm, a free length of 20 mm, and a maximum compression of 10 mm. The cylindrical clamping block 201 has a diameter of 8 mm.

[0030] The fixing component 3 includes a mounting block 301 fixedly connected to the other side of the lower clamping plate 1. The mounting block 301 has a cavity inside. A telescopic rod 302 is movably connected to the inner wall of the cavity. A tension spring 303 is connected between the bottom of the telescopic rod 302 and the inner bottom wall of the cavity. A fan-shaped plate 304 is fixedly connected to the top of the telescopic rod 302. It can be operated with one hand and is suitable for industrial scenarios where gloves are worn. A plug rod 305 is fixedly connected to the bottom of the fan-shaped plate 304. A slot that matches the plug rod 305 is opened on the other side of the top of the upper clamping plate 101. The tension spring 303 has an elastic coefficient of k2 = 8 N / mm, a free length of 30 mm, and a maximum tension of 15 mm.

[0031] Each U-shaped plate 102 has a clamping block 4 installed inside, which is adapted to wire harnesses of different diameters. The clamping block 4 is made of rubber, so that the clamping block 4 can be deformed to fit tightly to wire harnesses of different diameters, avoiding insecure fixing or crushing damage caused by wire harness diameter deviation.

[0032] The top of the upper clamping plate 101 is fixedly connected to a fixing seat, and a nameplate 5 is provided on the top of the fixing seat. Screws 6 are provided at the four corners of the nameplate 5. The nameplate 5 can mark the function, specifications or installation date of the wire harness, so that it is not necessary to check them one by one during maintenance.

[0033] A limiting ring 7 is sleeved on the surface of the telescopic rod 302. A limiting groove adapted to the limiting ring 7 is opened on the inner side wall of the cavity. The limiting ring 7 prevents the insertion rod 305 from being pulled out excessively, causing fixation failure, or from being pressed in excessively, damaging the slot of the upper clamping plate 101.

[0034] Rubber pads 8 are fixedly connected to the opposite side of the lower clamping plate 1 and the upper clamping plate 101. The surface of the rubber pads 8 is provided with V-shaped anti-slip texture. The rubber pads 8 can absorb the impact force when the clamping plates are closed, avoid the wire harness skin indentation caused by rigid contact, and protect the precision wire harness.

[0035] The bottom of the lower clamping plate 1 is fixedly connected to the mounting base 9. The top of the mounting base 9 has multiple countersunk holes. The countersunk hole design makes the head of the mounting screw flush with the surface of the mounting base 9, so as to avoid the protruding part scratching the wire harness or other components.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When installing the new clamping block 4, first align the cylindrical clamping block 201 of the U-shaped plate 102 with the mounting groove and insert it. The top of the cylindrical clamping block 201 pushes the arc-shaped clamping plate 203 to rotate outward, and the compression spring 205 stores force. When the cylindrical clamping block 201 is fully inserted, the compression spring 205 returns to its original position, and the arc-shaped clamping plate 203 clamps the cylindrical clamping block 201 with elastic force to complete the fixation.

[0038] Second step: When the upper clamping plate 101 rotates and closes around the rotating shaft, the slot on the other side of the upper clamping plate 101 aligns with the insertion rod 305 in the mounting block 301. At this time, the sector plate 304 moves downward with the telescopic rod 302, the insertion rod 305 is inserted into the slot, and the tension spring 303 applies a downward pulling force through the telescopic rod 302, so that the sector plate 304 is tightly pressed against the upper clamping plate 101, ensuring that the insertion rod 305 is locked with the slot.
