For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0022] As Figures 1 to 3 Indicated, a kind of power supply wire harness fixing structure of vehicle camera of the utility model, including upper cover 1, base 2, waterproof sealing assembly;

[0023] Upper cover 1 and base 2 are openable and closeable connection, upper cover 1 and base 2 are connected by the side press type lock 3, press type lock 3 is built-in spring, base 2 is internally provided with arc line groove 4, arc line groove 4 is used to install wire harness 6, arc line groove 4 is provided with U-shaped spring 5 to hold wire harness 6, waterproof sealing assembly is arranged at the entrance and exit of arc line groove 4, and waterproof sealing assembly includes conical silica gel sealing ring 7 and the rotating locking ring matched with it.

[0024] Specifically, in the embodiment, by setting the power supply wire harness 6 structure to include the split type structure of upper cover 1 and base 2, and using press type lock 3 connection, while press type lock 3 is built-in spring to provide bidirectional locking force, when needing to disassemble upper cover 1 and base 2 and take out wire harness 6 and U-shaped spring 5 in the arc line groove 4 in the inside of base 2, only need to press press type lock 3, so that upper cover 1 and base 2 are released from fixed. Therefore, in the embodiment, without the aid of tool, the power supply wire harness fixing structure can be quickly disassembled and replaced. Among them, camera can be arranged on the other side opposite wire harness 6. Figure 1

[0025] ​By setting the arc-shaped wire slot 4 inside the base 2 to install the wire harness 6, and setting the U-shaped spring 5 inside the arc-shaped wire slot 4, the U-shaped spring 5 can exert a radial clamping force on the wire harness 6 to clamp and fix the wire harness 6, thereby effectively reducing the vibration amplitude of the wire harness 6, thereby enhancing the fixing effect of the wire harness 6.

[0026] Specifically, as shown in Figure 3 the opening end of the U-shaped spring 5 faces the bottom of the arc-shaped wire slot 4, and the closed end is fixed to the side wall of the base 2 or the bottom of the upper cover 1 in a detachable manner such as buckling. The U-shaped spring 5 can be provided with multiple to enhance the fixing effect. The distance between the left and right side springs of the U-shaped spring 5 is slightly smaller than the diameter of the wire harness 6, ensuring that the spring is pre-deformed when the wire harness 6 is inserted. The bottom of the U-shaped spring 5 abuts the bottom of the arc-shaped wire slot 4, and the height of the inner surface of the spring from the bottom of the slot is 1.2-1.5 times the radius of the wire harness 6, to ensure that the wire harness 6 is clamped in the center of the slot.

[0027] When the wire harness 6 is inserted, the free end is pushed outward to expand, and the root of the spring is bent and deformed. The U-shaped spring 5 made of a memory alloy material can provide elastic restoring force. When the wire harness 6 is pushed along the arc-shaped wire slot 4, it contacts the free end of the spring and is pressed to both sides, and the spring is opened outward to the maximum opening angle. At this time, the spring produces energy storage deformation, and the super-elasticity of the memory alloy avoids plastic deformation. At the same time, since the U-shaped spring 5 can be adjusted relatively freely, it can be adapted to wire harnesses 6 of different diameters, thereby improving versatility.

[0028] A waterproof sealing assembly including a tapered silica gel sealing ring 7 and a rotating locking ring matched therewith is provided at the inlet and outlet of the arc-shaped wire slot 4, wherein the tapered silica gel sealing ring 7 can be compressed in the radial direction and matched with the outer diameter gap of the wire harness 6, and the inner wall of the rotating locking ring is provided with a spiral groove matched with the spiral groove provided on the tapered outer wall of the silica gel sealing ring 7. By tightening the rotating locking ring, the tapered silica gel sealing ring 7 and the wire harness 6 can be clamped and compressed from the outside to achieve a sealing effect. Therefore, the present embodiment can enhance the waterproof sealing effect of the wire harness 6, so that the wire harness 6 can still maintain sealing when the vehicle is jolted, and the inner diameter of the tapered silica gel sealing ring 7 is compressed and reduced by rotating the rotating locking ring, thereby achieving dynamic sealing.

[0029] In an alternative embodiment, a silica gel buffer layer 8 is provided at the bottom of the arc-shaped wire slot 4.

[0030] Specifically, by setting the silica gel buffer layer 8 at the bottom of the arc-shaped wire slot 4, three-way constraint can be achieved with the U-shaped spring 5, wherein the two side springs exert radial pressure, and the bottom silica gel buffer layer 8 provides axial friction. Therefore, the present embodiment can achieve locking of the wire harness 6, thereby enhancing the fixing effect of the wire harness 6.

[0031] In an alternative embodiment, the inner side of the end of the U-shaped spring 5 is provided with anti-slip teeth.

[0032] Specifically, by setting the anti-skid tooth pattern inside the end of the U-shaped elastic sheet 5, the clamping force of the U-shaped elastic sheet 5 can be decomposed into radial pressure and tangential anti-skid force through the sawtooth inclined surface of the anti-skid tooth pattern, and the tooth pattern is staggered to uniformly transmit the pressure to the skin of the wire harness 6.

[0033] After the wire harness 6 completely enters the wire slot, the free end of the U-shaped elastic sheet 5 rebounds inward under the action of the elastic restoring force, the anti-skid tooth pattern can be embedded to clamp the skin of the wire harness 6, and the vibration amplitude of the wire harness 6 can be effectively reduced through the cooperation of the U-shaped elastic sheet 5 and the silica gel buffer layer 8, so that the fixing and clamping effect of the wire harness 6 is further enhanced.

[0034] The distance between the lowest point of the anti-skid tooth pattern arranged inside the end of the U-shaped elastic sheet 5 and the surface of the silica gel buffer layer 8 is 0.2-0.5mm, so as to prevent the wire harness 6 from being hard contacted with the buffer layer.

[0035] In an alternative embodiment, the bottom of the base 2 is provided with a magnetic adsorption base plate, and the magnetic adsorption base plate comprises a permanent magnet layer and a bolt mounting hole.

[0036] Specifically, by simultaneously arranging the magnetic adsorption base plate comprising the permanent magnet layer and the bolt mounting hole at the bottom of the base 2, the dual-mode compatible installation of magnetic adsorption and bolt fixing can be realized, so that the base 2 can be conveniently fixed and installed.

[0037] In an alternative embodiment, a temperature-sensitive color-changing layer is embedded in the inside of the U-shaped elastic sheet 5.

[0038] Specifically, by embedding the temperature-sensitive color-changing layer in the inside of the U-shaped elastic sheet 5, color development can be prompted when overheating is detected, the working temperature of the wire harness 6 can be monitored in real time through the temperature-sensitive layer to prevent the overheating risk of the wire harness 6, and intelligent monitoring is realized.

[0039] In an alternative embodiment, the bottom of the arc-shaped wire slot 4 is provided with a heat dissipation through hole with a waterproof and breathable film.

[0040] Specifically, the heat dissipation through hole with a waterproof and breathable film is arranged at the bottom of the arc-shaped wire slot 4, so that the surface of the wire harness 6 can be cooled to prevent the wire harness 6 from overheating and malfunctioning.

[0041] The installation and disassembly process of the utility model:

[0042] During installation, the pressing type lock buckle 3 is pressed, the upper cover 1 is opened, the wire harness 6 is loaded into the arc-shaped wire slot 4 in the base 2, the conical silica gel sealing ring 7 is adjusted to the appropriate position, the upper cover 1 is reloaded, the U-shaped elastic sheet 5 can clamp and fix the wire harness 6, then the pressing type lock buckle 3 is locked, and the rotation locking ring is rotated to complete the sealing.

[0043] When disassembling, the press type lock 3 is pressed to release the fixing of the upper cover 1 and the base 2, the wire harness 6 can be taken out after the upper cover 1 is taken off.

The skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
