Among them, the automotive wiring harness distribution rack is a component for assisting in positioning the internal wiring harnesses of the vehicle. Therefore, the quality of the automotive wiring harness distribution rack determines the laying quality of the circuits; For example, the patent automotive wiring harness distribution rack with the publication number CN219371907U includes a distribution rack; the distribution rack is used for combing and fixing automotive wiring harnesses; it includes a bottom plate, and a detachable and hollow shell is installed above the bottom plate. A plurality of card slots are provided on the shell; cross plates are installed at the centers of the card slots, and clamping blocks that can move up and down and are used for clamping automotive wiring harnesses are installed above the cross plates; fixing frames are installed above the clamping blocks, and clamping blocks are installed at the bottom ends of both side walls of the fixing frames. The fixing frames pass through the card slots and are clamped with the card slots through the clamping blocks; that is, the automotive wiring harness is placed on the clamping grooves at the top ends of the clamping blocks, and the fixing frames pass through the card slots. Under the action of the clamping blocks, the automotive wiring harness can be clamped between the fixing frames and the clamping blocks without passing one end of the automotive wiring harness through between the fixing frame and the clamping block; this design is convenient to operate and is convenient for quickly fixing the automotive wiring harness; Another example is the patent automotive wiring harness distribution rack with the publication number CN221508989U, which includes two distribution racks. No less than two wiring grooves are provided on the two distribution racks, and a plurality of wire conduits corresponding to the positions of the wiring grooves are fixedly connected between the two distribution racks. The two ends of the wire conduit are fixedly communicated with the wiring grooves, and the wire conduit is a telescopic flexible tube. Positioning plates are provided on the inner walls of the plurality of wiring grooves, and movable rods are fixedly connected to one side of the positioning plates. According to the requirements of the actual bending angle, the two distribution racks are fixed on the vehicle body. The wire conduit can be bent along with the positions of the two distribution racks, can adapt to various angles, and can meet the different bending angle requirements of automotive wiring harnesses. At the same time, the wire conduit can separate the automotive wiring harnesses when they are bent, preventing the automotive wiring harnesses from being wound around each other at the bending points and affecting each other; A wiring harness distribution rack for an automobile, such as the one with the publication number CN218275870U, includes a wiring harness distribution rack body used in conjunction with an automobile frame. The wiring harness distribution rack body is fixedly connected to a mounting block, and the mounting block is detachably connected to the automobile frame. Among them, an installation groove is opened on the automobile frame, a clamping groove is provided on the inner wall of the installation groove, and a roller group is elastically positioned in the clamping groove; a square rod is provided on the mounting block, a tapered block is fixedly connected to the end of the square rod, and guide rails cooperating with the roller group are opened on both sides of the tapered block; a first limiting groove is opened on the side of the square rod, and the first limiting groove cooperates with an L-shaped block on the mounting block for limiting; a round rod is movably arranged on the second through groove, the middle of the round rod penetrates through the first through groove, and limiting discs are arranged at both ends of the round rod; the first through groove and the second through groove are perpendicular to each other. Most of the above-mentioned prior arts improve their overall structures. During the operation of the existing wiring harness distribution rack for automobiles, when the wiring harness of the automobile is wound due to vibration or the like, it is very likely to have problems such as excessive bending curvature or wire winding, resulting in the inability to ensure the support stability of the wiring harness. Moreover, the existing wiring harness needs to be repeatedly pressed and positioned during docking, and the subsequent disassembly and replacement are cumbersome, with certain limitations in use. Summary of the Invention

[0003] The purpose of the present invention is to provide a wiring harness distribution rack for an automobile with a wiring harness protection structure and its operation method, so as to solve the problems proposed in the above background technology, that is, when the wiring harness of the automobile is wound due to vibration or the like, it is very likely to have problems such as excessive bending curvature or wire winding, resulting in the inability to ensure the support stability of the wiring harness, and the existing wiring harness needs to be repeatedly pressed and positioned during docking, and the subsequent disassembly and replacement are cumbersome.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A wiring harness distribution rack for an automobile with a wiring harness protection structure and its operation method, including a reserved base and an auxiliary support member. An auxiliary support member is installed at the upper end of the reserved base to position the wiring harness to be installed through the auxiliary support member; a nested docking member is fixedly connected to the lower end of the auxiliary support member, and the nested docking member is docked with the inner end of the reserved base. A bottom support liquid bag is adhesively connected to the lower end of the auxiliary support member, and the bottom support liquid bag is mutually docked with the upper end of the reserved base. An auxiliary support structure is arranged inside the auxiliary support member to adaptively support the contacted wiring harness through the auxiliary support structure; a receiving and guiding groove is opened at the inner end of the auxiliary support member, and an auxiliary wire management structure is arranged between the receiving and guiding groove and the auxiliary support member to prevent the contacted wiring harness from being wound through the auxiliary wire management structure.

[0005] Further preferably, the auxiliary support structure is provided with a supply hose, and the supply hose is docked inside the bottom support liquid sac, and the supply hose penetrates along the inside of the auxiliary support member. An internal limiting liquid sac is adhesively connected inside the edge of the auxiliary support member, and the internal limiting liquid sac is connected to the end of the supply hose; A contact limiting component is nested and installed inside the auxiliary support member, and the lower end of the contact limiting component is docked with a lower end guiding support member, and the lower end guiding support member is docked with the inside of the auxiliary support member.

[0006] Further preferably, a reserved docking rod is docked inside the reserved base, and a torsion spring is fixedly connected between the outer side of the reserved docking rod and the inner side of the reserved base. A reserved docking rope assembly is wound around the outer side of the reserved docking rod, and the end of the reserved docking rope assembly is docked with the end of the nested docking member.

[0007] Further preferably, the auxiliary support member forms a multi-directional movable structure along the upper end of the reserved base through a spherical nested docking member, and the spherical nested docking member cooperates with the reserved docking rope assembly, the reserved docking rod and the torsion spring to form a traction and reset support structure.

[0008] Further preferably, during the process of the auxiliary support member moving through the spherical nested docking member, the bottom support liquid sac in contact is synchronously pressed, and the bottom support liquid sac supplies the internal limiting liquid sac through the supply hose. The deformed internal limiting liquid sac pushes the contact limiting component to form a lateral movement work.

[0009] Further preferably, the auxiliary wire management structure is provided with a receiving and guiding groove, and the receiving and guiding groove is opened inside the auxiliary support member. A reserved guiding support member is nested and installed inside the receiving and guiding groove, and a reset spring is fixedly connected to the lower end of the reserved guiding support member; An auxiliary wire management block is nested and installed at the upper end of the reserved guiding support member, and a torsion spring docking shaft is docked between the auxiliary wire management block and the reserved guiding support member. A reserved magnet piece is fixedly connected to the outer side of the auxiliary wire management block, and an external protruding magnetic piece is fixedly connected to the inside of the auxiliary support member, and the external protruding magnetic piece and the reserved magnet piece are like-named magnetic poles.

[0010] Further preferably, during the process of the contact limiting component driving the lower end guiding support member to move along the inside of the receiving and guiding groove, the lower end guiding support member synchronously presses the contact inclined surface reserved guiding support member, and the reserved guiding support member moves upward along the inside of the auxiliary support member under the force.

[0011] Further preferably, during the process of the reserved guiding support member moving upward, it pushes the auxiliary wire management block to move upward synchronously. When the auxiliary wire management block moves upward to contact the external protruding magnetic piece, it moves at an angle along the surface of the reserved guiding support member through the like-named repulsive force.

[0012] Further preferably, an automotive wiring harness distribution frame with a wiring harness protection structure, and an operating method of the automotive wiring harness distribution frame are disclosed, and the specific method steps are as follows: S1: The auxiliary support member moves along the upper end of the reserved base through the spherical nested docking member, so as to meet the line movement requirements in different situations and prevent the rigid positioning state from causing excessive damage to the bound wire harness; S2: During the movement of the auxiliary support, the bottom support liquid bag in contact is pre-pressurized synchronously, so that the bottom support liquid bag can supply the internal limit liquid bag through the supply hose, and the internal limit liquid bag pushes the contact limit component to form a lateral movement through the deformation of the internal limit liquid bag, so that as long as the equipment shakes, the protection and positioning of the wire harness can be adaptively performed; S3: The resistance limit assembly drives the lower guide support to simultaneously apply pressure to the contacting inclined reserved guide support, thereby pushing the reserved guide support and the auxiliary wire management block to move upward along the inner side of the auxiliary support. When the auxiliary wire management block moves upward to contact the external raised magnetic part, it moves along the surface of the reserved guide support through the repulsive forces of the same name, thereby effectively dispersing the contacting multi-strand wire management.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The automotive wiring harness distribution frame with a wiring harness protection structure and the operation method thereof are provided with an auxiliary support structure, and the contacting wiring harness is adaptively supported by the auxiliary support structure. After the wiring harness to be placed is placed inside the auxiliary support member, the basic positioning work of the wiring harness can be performed by the protruding structures on both sides of the upper end of the auxiliary support member, and the user does not need to perform various binding processes later. When the equipment vibrates or the line is bent, the pre-stressed auxiliary support member will move along the upper end of the reserved base through the spherical nested docking member, thereby meeting the line activity requirements in different situations and preventing the rigid positioning state from causing excessive damage to the bound wiring harness. Furthermore, during the movement of the auxiliary support member, the bottom support liquid bag in contact will be pre-pressurized synchronously, so that the bottom support liquid bag can supply the internal part of the built-in limit liquid bag through the supply hose, and the built-in limit liquid bag can push the resistance limit component to form a lateral movement. Therefore, as long as the equipment shakes or other conditions occur, the protection and positioning of the wire harness can be adaptively performed without additional positioning operation steps. When the automobile wire harness is wound due to vibration, the support stability of the wire harness is guaranteed, and at the same time, the wire harness can avoid repeated pressing and positioning operations during the docking process, which makes the later disassembly and replacement cumbersome, thereby improving the practicality of the device. Furthermore, an auxiliary wire-managing structure is provided, through which the contacting wire harness is prevented from being entangled. In the process that the resistance limit component drives the lower end guide support to move along the inside of the auxiliary support, the guide support at its lower end will simultaneously apply pressure to the contacting inclined surface reserved guide support, thereby pushing the reserved guide support and the auxiliary wire-managing block to move upward along the inner side of the auxiliary support under force, and when the auxiliary wire-managing block moves upward to contact the external raised magnetic part, it moves at an angle along the surface of the reserved guide support through the repulsive forces of the same name, thereby effectively dispersing the contacting multi-strand wire management, and cooperating with the inwardly moving resistance limit component to perform adaptive positioning and synchronization on the wire-managing state, thereby improving the adaptive effect of the device.

The lower end of the auxiliary support member 3 is adhesively connected to a bottom support liquid sac 4, and the bottom support liquid sac 4 is docked with the upper end of the reserved base 1. An auxiliary support structure is arranged inside the auxiliary support member 3 to adaptively support the contacted wire harness; the auxiliary support structure is provided with a supply hose 5, and the supply hose 5 is docked inside the bottom support liquid sac 4 and penetrates along the inside of the auxiliary support member 3. An internal limit liquid sac 6 is adhesively connected to the inner side of the edge of the auxiliary support member 3, and the internal limit liquid sac 6 is connected to the end of the supply hose 5; a contact limit component 7 is nested and installed inside the auxiliary support member 3, and the lower end of the contact limit component 7 is docked with a lower end guiding support member 8, and the lower end guiding support member 8 is docked with the inside of the auxiliary support member 3.

[0018] A reserved docking rod 16 is docked inside the reserved base 1, and a torsion spring 18 is fixedly connected between the outer side of the reserved docking rod 16 and the inner side of the reserved base 1. A reserved docking rope assembly 17 is wound around the outer side of the reserved docking rod 16, and the end of the reserved docking rope assembly 17 is docked with the end of the nested docking member 2. The auxiliary support member 3 forms a multi-directional movable structure along the upper end of the reserved base 1 through the spherical nested docking member 2, and the spherical nested docking member 2 cooperates with the reserved docking rope assembly 17, the reserved docking rod 16, and the torsion spring 18 to form a traction and reset support structure.

[0019] During the movement of the auxiliary support member 3 through the spherical nested docking member 2, the bottom support liquid sac 4 in contact is synchronously pressurized, and the bottom support liquid sac 4 supplies the inside of the built-in limit liquid sac 6 through the supply hose 5. The deformed built-in limit liquid sac 6 pushes the contact limit component 7 to form a lateral movement. When the device vibrates or the circuit is bent, etc., the pre-loaded auxiliary support member 3 will move along the upper end of the reserved base 1 through the spherical nested docking member 2, so as to meet the circuit movement requirements in different situations and prevent the hard positioning state from causing excessive damage to the bundled wire harness.

The deformed built-in limit liquid sac 6 pushes the contact limit component 7 to form a lateral movement. As long as the device shakes, etc., the wire harness can be adaptively protected and positioned without additional positioning operation steps. When the automotive wire harness is wound due to vibration, etc., the support stability of the wire harness is ensured, and at the same time, it is avoided that the wire harness needs to be repeatedly pressed and positioned during docking.

[0022] During the upward movement of the reserved guiding support member 10, the auxiliary wire arranging block 11 is pushed to move upward synchronously. When the auxiliary wire arranging block 11 moves upward to contact the external protruding magnetic member 14, it performs angular movement along the surface of the reserved guiding support member 10 through the like-name repulsive force. During the process that the contact limiting component 7 drives the lower-end guiding support member 8 to move inside the auxiliary support member 3, the lower-end guiding support member 8 at its lower end will simultaneously press on the contact inclined surface reserved guiding support member 10, thereby pushing the reserved guiding support member 10 and the auxiliary wire arranging block 11 to move upward along the inner side of the auxiliary support member 3 under force.

The deformed built-in limiting liquid sac 6 is used to push the contact limiting component 7 to form a lateral movement operation. Thus, as long as the device shakes or the like, the wire harness is adaptively protected and positioned. S3: When the contact limiting component 7 drives the lower-end guiding support member 8 to simultaneously press on the contact inclined surface reserved guiding support member 10, the reserved guiding support member 10 and the auxiliary wire arranging block 11 are pushed to move upward along the inner side of the auxiliary support member 3 under force. When the auxiliary wire arranging block 11 moves upward to contact the external protruding magnetic member 14, it performs angular movement along the surface of the reserved guiding support member 10 through the like-name repulsive force, thereby effectively performing a dispersion wire arranging process on the contacted multi-strand wires.
