[0029] In the related art, with the rapid development of the automotive industry, especially the upgrade and iteration of intelligent assisted driving vehicles, the communication between various in-vehicle controllers has become more and more complex. The wiring harness will naturally become thicker and more difficult to bend, and the perforation size needs to be increased. The wiring harness through-hole device generally consists of a flexible part and a support skeleton. The flexible part and the support skeleton are clamped and matched. During the transportation of the vehicle, the flexible part and the support skeleton are likely to be separated and fall off, thus affecting the reliability and safety of the wiring harness during vehicle operation.
[0030] Reference will be made below to Figures 1 - 4 describe a wiring harness through-hole device according to an embodiment of the present utility model.
[0031] The wiring harness through-hole device 100 for a vehicle according to the present utility model includes: a flexible part 11, a support skeleton 21, and a limiting member 31. The flexible part 11 is respectively formed with a first clamping surface and a first limiting surface on both sides in the thickness direction, and a first mounting hole 115 is formed on the first limiting surface; the support skeleton 21 is connected to the vehicle body, and a second clamping surface matching the first clamping surface is formed on one side of the support skeleton 21 in the thickness direction, and a second limiting surface is formed on the other side of the support skeleton 21 in the thickness direction, and a second mounting hole 212 disposed opposite to the first mounting hole 115 is formed on the second limiting surface; the limiting member 31 respectively passes through the first mounting hole 115 and the second mounting hole 212, and at least part of the outer circumference of the limiting member 31 is formed with a first matching part and a second matching part 313. The first matching part abuts against the first limiting surface, and the second matching part 313 abuts against the second limiting surface to limit the axial movement of the flexible part 11 relative to the support skeleton 21.
[0032] In some specific embodiments, the wire harness through-hole device 100 is composed of a flexible part 11, a support skeleton 21, and a limiting part 31. A first clamping surface is formed on one side of the flexible part 11 in the thickness direction, and a second clamping surface is formed on one side of the support skeleton 21 in the thickness direction. The first clamping surface cooperates with the second clamping surface, so that at least part of the support skeleton 21 is closely attached to at least part of the flexible part 11, realizing the connection between the support skeleton 21 and the flexible part 11. A first limiting surface is formed on the other side of the flexible part 11 in the thickness direction, and a second limiting surface is formed on the other side of the support skeleton 21 in the thickness direction. A first mounting hole 115 is formed on the first limiting surface, and a second mounting hole 212 which is arranged opposite to the first mounting hole 115 is formed on the second limiting surface. The first mounting hole 115 penetrates through the flexible part 11 in the thickness direction, and the second mounting hole 212 penetrates through the support skeleton 21 in the thickness direction. At least part of the limiting part 31 respectively passes through the first mounting hole 115 and the second mounting hole 212, and at least part of the outer periphery of the limiting part 31 forms a first matching part and a second matching part 313. The first matching part abuts against the first limiting surface, and the second matching part 313 abuts against the second limiting surface. When the flexible part 11 moves axially relative to the support skeleton 21, the flexible part 11 and the support skeleton 21 will be blocked by the first matching part and the second matching part 313 respectively, thereby restricting the axial movement of the flexible part 11 relative to the support skeleton 21, improving the stability and reliability of the connection between the flexible part 11 and the support skeleton 21 during the movement of the vehicle, and enhancing the stability and reliability of the wire harness located in the wire harness through-hole device 100.
[0033] According to the wire harness through-hole device 100 of the present invention, a first clamping surface is formed on one side of the flexible part 11 in the thickness direction, and a second clamping surface is formed on one side of the support skeleton 21 in the thickness direction. The first clamping surface cooperates with the second clamping surface to realize the connection between the support skeleton 21 and the flexible part 11. A first limiting surface is formed on the other side of the flexible part 11 in the thickness direction, and a second limiting surface is formed on the other side of the support skeleton 21 in the thickness direction. A first mounting hole 115 is formed on the first limiting surface, and a second mounting hole 212 which is arranged opposite to the first mounting hole 115 is formed on the second limiting surface. At least part of the limiting part 31 respectively passes through the first mounting hole 115 and the second mounting hole 212. A first matching part and a second matching part 313 are formed on the outer periphery of the limiting part 31. The first matching part abuts against the first limiting surface, and the second matching part 313 abuts against the second limiting surface to restrict the axial movement of the flexible part 11 relative to the support skeleton 21, improving the stability and reliability of the connection between the flexible part 11 and the support skeleton 21 during the movement of the vehicle, and enhancing the stability and reliability of the wire harness located in the wire harness through-hole device 100.
[0034] According to some embodiments of the present utility model, the limiting member 31 includes: a base 311 and a protruding portion 312. The base 311 is configured as a first mating portion, and at least a part of the outer periphery of the base 311 abuts against the first limiting surface; the protruding portion 312 is disposed on the base 311, and a second mating portion 313 protruding away from the protruding portion 312 is formed on the outer periphery of the protruding portion 312.
[0035] In some specific embodiments, the limiting member 31 is composed of the base 311 and the protruding portion 312. The first mating portion can be configured as the base 311. The protruding portion 312 is disposed on the base 311. One side of the base 311 facing the protruding portion 312 abuts against the first limiting surface to limit the movement of the flexible portion 11 in the direction away from the support skeleton 21. A second mating portion 313 protruding away from the protruding portion 312 is formed on the outer periphery of the protruding portion 312. The second mating portion 313 abuts against the second limiting surface to limit the movement of the support skeleton 21 in the direction away from the flexible portion 11, improving the stability and reliability of the connection between the flexible portion 11 and the support skeleton 21 during the movement of the vehicle, and enhancing the stability and reliability of the wire harness within the wire harness through-hole device 100.
[0036] According to some embodiments of the present utility model, a notch 101 extending axially is formed at the center of the end of the protruding portion 312 away from the base 311, enabling the protruding portion 312 to deform to a certain extent towards the notch 101. When the protruding portion 312 is inserted into the first mounting hole 115 and the second mounting hole 212, it can conform to the shape of the holes of the first mounting hole 115 and the second mounting hole 212 and deform moderately, thereby ensuring that the limiting member 31 can closely fit the hole wall, reducing the assembly difficulty of the limiting member 31, and improving the assembly efficiency of the wire harness through-hole device 100.
[0037] According to some embodiments of the present utility model, the first mounting holes 115 are configured as a plurality of spaced-apart ones, and the second mounting holes 212 are configured as a plurality corresponding one-to-one to the first mounting holes 115, increasing the connection points between the support skeleton 21 and the flexible portion 11, thereby improving the stability and reliability of the connection between the support skeleton 21 and the flexible portion 11. At the same time, the plurality of first mounting holes 115 and the plurality of second mounting holes 212 are evenly spaced on the flexible portion 11 and the support skeleton 21 respectively, which can effectively avoid stress concentration and thus reduce the risk of local overload.
[0038] According to some embodiments of the present utility model, the flexible portion 11 includes: an outer peripheral portion 111, a flexible connecting portion 112, and a tube portion 113. A first clamping surface is formed on one side of the outer peripheral portion 111 in the thickness direction and abuts against the support skeleton 21. The outer peripheral portion 111 is disposed in a surrounding manner; the flexible connecting portion 112 is disposed on the inner periphery of the outer peripheral portion 111; the tube portion 113 is connected to the flexible connecting portion 112 and forms a through wire harness through-hole.
[0039] In some specific embodiments, the flexible part 11 is composed of an outer peripheral part 111, a flexible connecting part 112 and a tube body part 113. The outer peripheral part 111 plays a role in supporting and positioning to a certain extent. A first clamping surface is formed on one side of the outer peripheral part 111 in the thickness direction. The first clamping surface can be used to cooperate with the second clamping surface formed on the support skeleton 21 to limit the movement of the flexible part 11 relative to the support skeleton 21. The outer peripheral part 111 is disposed around the outer periphery of the flexible connecting part 112. A tube body part 113 extending axially is formed inside the flexible connecting part 112. A wire harness through hole penetrating axially is formed inside the tube body part 113, and the wire harness is accommodated in the wire harness through hole, effectively preventing the wire harness from being worn, bent or interfered by the outside world, and improving the stability and reliability of the wire harness on the vehicle.
[0040] According to some embodiments of the present invention, reinforcing ribs 114 connecting the outer peripheral part 111 and the flexible connecting part 112 are formed on the outer periphery of the tube body part 113.
[0041] In some specific embodiments, a plurality of mutually staggered reinforcing ribs 114 are provided on the outer periphery of the tube body part 113. The reinforcing ribs 114 are connected to the outer peripheral part 111 and the flexible connecting part 112. The arrangement of the reinforcing ribs 114 can enhance the overall structural strength and stiffness of the flexible part 11. When the tube body part 113 is subjected to tensile, compressive or torsional deformation, the reinforcing ribs 114 can effectively disperse stress and prevent damage caused by local overload of the tube body part 113, ensuring the morphological stability of the tube body part 113 and the stability and safety of the wire harness inside the tube body part 113.
[0042] According to some embodiments of the present invention, the flexible part 11 is configured as a rubber part. The rubber part can be configured as EPDM (ethylene propylene diene monomer). EPDM has excellent ozone resistance, heat resistance and chemical corrosion resistance, and can maintain good performance even when exposed to the external environment for a long time, and is not easily degraded due to ultraviolet radiation, oxygen, high temperature or chemical action, ensuring the stability and reliability of the wire harness through hole device 100 for long-term use. At the same time, EPDM rubber has good wear resistance, electrical insulation performance and good resistance to water and water vapor, and can act as a sealing part to play a certain sealing role for the wire harness.
[0043] According to some embodiments of the present utility model, a positioning portion 211 is formed on the support frame 21. The positioning portion 211 is adapted to be positioned with the vehicle body. The positioning portion 211 is composed of a main positioning hole, an auxiliary positioning hole, and two mounting holes. The main positioning hole can be designed as a circular hole with precise dimensions to achieve precise docking with a positioning pin or fastener provided on the vehicle body, ensuring that the position of the entire support frame 21 in the vehicle body is correct. The auxiliary positioning hole can be configured as an oval hole. The existence of the oval hole allows for a certain amount of floating in a certain direction of the support frame 21 (usually along the long axis direction of the oval). This design can absorb displacements caused by manufacturing tolerances, assembly deviations, or material deformations, improving the flexibility and adaptability of the connection between the support frame 21 and the vehicle. The design of the two mounting holes increases the connection points between the support frame 21 and the vehicle body, further improving the stability and reliability of the connection between the vehicle body and the support frame 21.
[0044] According to some embodiments of the present utility model, an avoidance notch 102 for avoiding the positioning portion 211 is formed on the outer peripheral portion 111. The avoidance notch 102 can, on the premise of not affecting the overall structural strength and stability of the flexible portion 11, allow the positioning portion 211 on the support frame 21 (such as the main positioning hole, auxiliary positioning hole, or mounting hole mentioned above) to be connected to the corresponding vehicle body structure without obstruction, avoiding interference between the outer peripheral portion 111 of the flexible portion 11 and the positioning portion 211, thereby ensuring the precise positioning and smooth assembly between the positioning portion 211 and the vehicle body.
