Description

Technical Field

[0001] The utility model relates to the technical field of automobile floors, in particular to an automobile floor harness protection device. Background Art

[0002] The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and wiring harness capacity. Therefore, wiring harness is an important basic concept in traffic theory.

[0003] The inventor discovered during the process of implementing the utility model:

[0004] A patent document with announcement number CN217642479U discloses a car floor wiring harness fixer. The second clamp can be opened by pushing the paddle block upwards, and multiple wiring harnesses can be placed between the first clamp and the second clamp. The second clamp can be closed by loosening the paddle block, so that multiple wiring harnesses can be quickly fixed. The elastic force of the torsion spring can prevent the second clamp from moving, thereby improving stability.

[0005] In the technical solution of the above patent, although the wiring harness can be placed between the first clip and the second clip for fixation, there is still space between the wiring harness and the clips. For example, when the vehicle is driving, vibrations and shaking are generated due to factors such as uneven roads, acceleration or deceleration of the vehicle, and these vibrations and shaking will cause the wiring harness to continuously contact and rub against the clips. This continuous friction will gradually weaken the protective layer on the outside of the wiring harness, causing its insulating material to be worn. As time goes by, the internal conductive cable will eventually be exposed, affecting its use. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the utility model proposes an automobile floor wiring harness protection device.

[0007] To this end, the technical solution of the utility model is: an automobile floor harness protection device, comprising a mounting plate, an inverted U-shaped plate is fixed to the upper surface of the mounting plate, two moving plates are slidably connected between the upper surface of the mounting plate and the U-shaped plate, and a clamping assembly for driving the moving plate to move is arranged on the side of the U-shaped plate;

[0008] A fixing shell is fixed on one side of the two movable plates which are away from each other. The fixing shell penetrates the movable plates and is provided with a protection component for fixing the wire harness.

[0009] Furthermore, the clamping assembly includes a threaded rod rotatably connected to one side of the movable plate, and one end of the threaded rod away from the movable plate passes through the outside of the U-shaped plate and is threadedly connected to the U-shaped plate, and a handle is fixed to one end of the threaded rod located outside the U-shaped plate.

[0010] Furthermore, the clamping assembly also includes a limiting rod fixed on one side of the movable plate, and the end of the limiting rod away from the movable plate passes through the outside of the U-shaped plate and is slidably connected to the U-shaped plate, which can further guide and limit the movement of the U-shaped plate.

[0012] Furthermore, a slide plate is fixed to one end of the slide rod located inside the fixed shell, and the outer surface of the slide plate is slidably connected to the inner wall of the fixed shell, and a telescopic spring is arranged inside the fixed shell.

[0013] Furthermore, the mounting plate is provided with mounting holes, and the mounting holes are located at the four corners of the mounting plate, so that the device can be installed on the car floor.

[0023] Figure 1 As shown, in this embodiment, the clamping assembly 3 includes a threaded rod 301 rotatably connected to one side of the moving plate 6, and one end of the threaded rod 301 away from the moving plate 6 penetrates to the outside of the U-shaped plate 4 and is threadedly connected to the U-shaped plate 4, and one end of the threaded rod 301 located outside the U-shaped plate 4 is fixed with a handle 302.

[0024] The clamping assembly 3 further includes a limiting rod 303 fixed to one side of the moving plate 6, and one end of the limiting rod 303 away from the moving plate 6 penetrates the outside of the U-shaped plate 4 and is slidably connected to the U-shaped plate 4, which can further guide and limit the movement of the U-shaped plate 4;

[0025] In this embodiment, the threaded rod 301 can be driven to rotate by turning the handle 302, and the rotation of the threaded rod 301 can drive the movable plate 6 to move. The movement of the movable plate 6 will follow the limiting rod 303, so that wire harnesses of different diameters can be fixed.

[0026] like Figure 1 As shown, in this embodiment, a fixed shell 5 is fixed on the side of the two moving plates 6 that are away from each other, and the fixed shell 5 penetrates the moving plate and is provided with a protective component 2 for fixing the wire harness.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the protection component 2 includes a slide bar 201 slidably connected to the inner wall of the hole of the movable plate 6, and one end of the slide bar 201 is located inside the fixed shell 5. The slide bar 201 is square in shape, and the movement of the slide bar 201 can be limited to avoid rotation. The outer surface of the slide bar 201 is slidably connected to an arc plate 202, and the arc plate 202 is provided with a through hole adapted to the slide bar 201. Both ends of the arc plate 202 are hinged to a limit plate 203, and one end of the limit plate 203 is hinged to an elastic band 204. A moving rod 205 is fixed to the end of the slide bar 201 away from the fixed shell 5, and the moving rod 205 is located between the elastic band 204 and the arc plate 202, and the material of the elastic band 204 is a retractable material;

Then, the threaded rod 301 can be driven to rotate by turning the turning handle 302. The rotation of the threaded rod 301 can drive the movable plate 6 to move. The movement of the movable plate 6 will follow the limiting rod 303, so that wiring harnesses of different diameters can be fixed. When the wiring harness shakes due to the driving of the vehicle, the wiring harness will squeeze the elastic band 204, and the contraction of the elastic band 204 will tighten the limiting plate 203, so that the limiting plate 203 fits on the wiring harness to keep it stable. If the shaking is too large, the moving rod 205 will continue to be pushed. The moving rod 205 squeezes the telescopic spring 207 through the sliding rod 201 and the sliding plate 206. Under the action of the telescopic spring 207, the force is offset, so that the wiring harness is kept stable and fixed, avoiding the friction caused by the shaking of the wiring harness, which may cause the internal conductive cable to be exposed, affecting its use.
