Description

Technical Field

[0001] This invention relates to the field of wire harness installation technology, specifically to an expandable modular splicing structure for wire harness installation. Background Technology

[0002] As a key component for power and signal transmission in electrical systems, wire harnesses are traditionally designed with fixed specifications, resulting in weak adaptability and scalability. This leads to insufficient flexibility in wiring under different scenarios. To adapt to diverse wiring needs and improve the adaptability and scalability of wire harness installation, modular splicing structures have become the industry trend. Through detachable and combinable modular units, the installation path and specifications of wire harnesses can be flexibly adjusted to meet different installation space and wiring quantity requirements, thereby improving the standardization and convenience of wire harness layout.

[0003] A search revealed a Chinese patent for a wire harness unit and its mounting structure, with application publication number CN113574284B. This patent describes a wire harness unit mounted on a housing, comprising a wire harness and a retainer. The wire harness has multiple covered wires fixed to a sheet-like substrate. The retainer has: a pair of clamping portions that hold a portion of the substrate that is different from the portion where the multiple covered wires are fixed; and a fitting portion that fits into the fitting portion in the left-right direction relative to the fitting portion disposed on the housing, thereby locking it in the front-back direction.

[0004] During the installation of wire harnesses, installation structures are used to install them according to the current condition of the wire harnesses. The problem with existing technology is that it lacks an expandable modular splicing structure for the parallel installation of multiple wire harnesses. Therefore, it cannot adapt to the situation where multiple wire harnesses are installed in parallel in some areas, which reduces the flexibility of installing multiple parallel wire harnesses. Furthermore, it lacks an installation structure that is adaptable to wire harnesses of different shapes, so it cannot adapt to the installation of wire harnesses of different shapes, thus reducing the flexibility of installing wire harnesses of different shapes. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an expandable modular splicing structure for wire harness installation. This structure allows for the expansion of multiple wire harnesses for parallel installation, thus accommodating multiple parallel, expandable installation limits in certain areas. This improves the flexibility of installing multiple parallel wire harnesses. Furthermore, it possesses an adaptable installation structure for wire harnesses of different shapes, further enhancing the flexibility of installing wire harnesses of varying shapes.

[0006] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: an expandable modular splicing structure for wire harness installation, comprising a guiding mechanism and a positioning mechanism, wherein the positioning mechanism is disposed inside the guiding mechanism, the guiding mechanism comprises a splicing component, an adjusting component, a fixing component and a limiting component, the adjusting component is disposed on the top of the splicing component, the fixing component is disposed on the front side of the top of the adjusting component, the limiting component is disposed on the top of the adjusting component, the positioning mechanism comprises a flow guiding component, a guiding component, a clamping component, a guiding component and a wire fixing component, the flow guiding component is disposed on the top of the splicing component, the guiding component is disposed on the front and rear sides of the top of the flow guiding component, the clamping component is disposed inside the guiding component, the guiding component is disposed on the top of the flow guiding component, and the wire fixing component is disposed on the surface of the guiding component.

[0007] By adopting the above technical solution, and by setting up a guiding mechanism and a positioning mechanism, the guiding mechanism can provide installation limits for the wire harness, and can be spliced ​​with multiple guiding mechanisms to achieve modular expansion. The positioning mechanism can adaptively limit the wire harness according to its shape, increasing the stability of the wire harness during installation.

[0008] The present invention is further configured such that: the splicing assembly includes a mounting base plate, a splicing plate, and connecting holes, the splicing plate is bolted to the front and rear sides of the inner side of the mounting base plate, and the connecting holes are formed on the surface of the splicing plate.

[0009] By adopting the above technical solution, by setting up splicing components, the mounting base plate, the assembly plate, and the connecting holes form an assembly structure that can be assembled into a modular and expandable structure, thereby providing support for multiple guide mechanisms. By using the mounting base plate to support the assembly plate, the mounting base plate can be installed at the required installation position by external bolts. The assembly plate can be connected to the connecting holes on another set of splicing components by bolts through the connecting holes, forming a modular expansion connection.

[0010] The present invention is further configured such that: the adjusting assembly includes a guide frame, a limiting plate and a cover plate, the guide frame is bolted to both sides of the mounting base plate, the limiting plate is bolted to the bottom of the inner side of the guide frame, and the cover plate is rotatably connected between opposite sides of the guide frame.

[0011] By adopting the above technical solution, the wire guide structure composed of the wire frame, the limiting plate, and the cover plate, formed by setting the adjustment component, can guide the wire harness and limit the wire harness within the positioning mechanism. The wire harness limiting and guiding structure composed of the wire frame and the limiting plate can provide guidance on both sides when the wire harness is installed in the positioning mechanism, and the cover plate can limit the wire harness within the positioning mechanism.

[0012] The present invention is further configured such that: the fixing component includes a slide rod, a limiting plug, and a return spring; the slide rod is slidably connected to the front side of the top of the guide frame; the limiting plug is welded to the opposite side of the slide rod; the return spring is installed on the inner side of the front side of the top of the guide frame; and the opposite side of the return spring contacts both sides of the slide rod.

[0013] By adopting the above technical solution, and by setting a fixed component, the slide bar can form a structure for limiting the cover plate with the limiting rod and the return spring. It can limit the cover plate when it is closed. By pulling the limiting rod to both sides, the slide bar can be moved within the guide frame, allowing the slide bar to be temporarily removed from the cover plate. When it is necessary to limit the cover plate, the return spring can use its own elasticity to push the limiting rod, thereby limiting the slide bar to the cover plate.

[0014] The present invention is further configured such that: the limiting component includes a nut sleeve, a screw, and an adjusting head; the nut sleeve is welded to the top of the cover plate; the screw is threaded to the inner side of the nut sleeve; and the adjusting head is welded to the top of the screw.

[0015] By adopting the above technical solution, and by setting a limiting component, the nut sleeve can form a structure with the screw and the adjusting head to adjust the internal pressure of the guide component. By changing the internal pressure of the guide component, the stability of limiting wire harnesses of different shapes can be further adapted. By limiting the screw with the nut sleeve, the user can rotate the adjusting head to drive the screw to rotate, allowing the screw to move up and down in the nut sleeve, thereby maintaining the current position after changing the pressure of the guide component.

[0016] The present invention is further configured such that: the flow guiding assembly includes a flow divider plate, a flow guiding hole and an inlet hole, the flow divider plate is bolted to the top of the inner side of the mounting base plate, the flow guiding hole is opened on the front and rear sides of the top of the flow divider plate, and the inlet hole is opened on the top of the flow divider plate.

[0017] By adopting the above technical solution, the air pressure guiding structure composed of the flow guiding component, the flow divider plate, the flow guiding hole, and the inlet hole can connect the air pressure in the clamping component with the guiding component. Thus, the air pressure in the clamping component can be changed at the same time as the air pressure in the guiding component changes. Through the cavity of the flow divider plate itself, the air pressure in the guiding component and the guiding component can be interconnected through the flow guiding hole and the inlet hole, which facilitates the subsequent adaptation to wire harnesses of different shapes.

[0018] The present invention is further configured such that: the guiding component includes a limiting cylinder, a buffer groove and a guiding groove, the limiting cylinder is connected to the top of the guide hole, the buffer groove is opened on the inner side of the limiting cylinder, and the guiding groove is opened on the opposite side of the inner side of the limiting cylinder.

[0019] By adopting the above technical solution, the guide component, the limiting cylinder, the buffer groove, and the guide groove together form a guide structure for the movement of the clamping component. This structure can guide the deformation direction of the clamping component caused by changes in internal air pressure. The limiting cylinder itself is cylindrical, which can adapt to the shape of the clamping component. The guide groove can guide the deformation direction of the clamping component and guide its position relative to the guide component. The buffer groove can provide a buffer space for the deformation of the clamping component when it is squeezed after contacting the wire harness, thus preventing it from rupturing due to unstable internal air pressure.

[0020] The present invention is further configured such that: the clamping assembly includes a one-way airbag, a corrugated pipe section and a contact plate, the one-way airbag is connected to the top of the guide hole, the corrugated pipe section is connected to the side opposite to the one-way airbag, and the contact plate is installed on the side opposite to the corrugated pipe section.

[0021] By adopting the above technical solution, the clamping structure for wire harnesses, consisting of a one-way airbag, a corrugated section, and a contact plate, can work in conjunction with the wire fixing assembly to clamp the wire harnesses. Simultaneously, the wire harnesses are clamped in a corrugated shape, increasing stability during installation. When the internal air pressure of the one-way airbag increases, the air pressure is delivered to the corrugated section. Guided by the guide groove, the corrugated section moves the contact plate towards the wire harness, thereby clamping it.

[0022] The present invention is further configured such that: the guiding component includes an expansion airbag, a cross groove frame and a guide port, the expansion airbag is connected to the top of the inlet hole, the cross groove frame is bolted to the top of the diverter plate, the guide port is opened at the top of the cross groove frame, and the expansion airbag is located inside the cross groove frame.

[0023] By adopting the above technical solution, the guide structure composed of the expanding airbag, the cross-groove frame, and the guide port, provided guidance for the displacement of the wire-fixing assembly, can change its internal air pressure as the wire-fixing assembly moves. This changes the air pressure inside the unidirectional airbag through the flow guide component, thereby clamping the wire harness. As the wire harness pushes the wire-fixing assembly along the cross-groove frame toward the expanding airbag, the air pressure inside the expanding airbag changes. This changes the air pressure inside the unidirectional airbag through the flow guide component, allowing the clamping assembly to clamp the wire harness. Furthermore, the guide port allows the screw to extend, further compressing the expanding airbag, thereby increasing the air pressure inside the expanding airbag, the flow guide component, and the unidirectional airbag, thus further increasing the stability of the wire harness clamping.

[0024] The present invention is further configured such that: the wire fixing assembly includes a pressing plate, a guide plate and a push plate, the pressing plate is disposed on the surface of the expansion airbag, the guide plate is welded to the side of the pressing plate away from the expansion airbag, the surface of the guide plate is slidably connected to the inner side of the cross groove frame, and the push plate is welded to the side of the guide plate away from the expansion airbag.

[0025] By adopting the above technical solution, the wire harness limiting structure composed of a wire fixing component, a pressing plate, a guide plate, and a push plate can cooperate with the clamping component to clamp the wire harness. It can also adapt to wire harnesses of different shapes and change the air pressure inside the expansion airbag. Through the I-shaped structure composed of the pressing plate, the guide plate, and the push plate, after the push plate contacts the wire harness, the guide plate drives the pressing plate to squeeze the expansion airbag along the cross groove frame, thereby changing the air pressure inside the expansion airbag. At the same time, after the air pressure inside the expansion airbag, the flow guiding component, and the one-way airbag is balanced, it adapts to the shape of the wire harness, realizes the clamping of the wire harness, and completes the installation of the wire harness.

[0026] (III) Beneficial Effects Compared with the prior art, the present invention provides an expandable modular splicing structure for wire harness installation, which has the following advantages: This is an expandable modular splicing structure for wire harness installation. It includes a wire harness installation and limiting structure composed of a guide mechanism, splicing components, adjustment components, fixing components, and limiting components. It can be spliced ​​with multiple guide mechanisms to achieve modular expansion. A mounting base plate, splicing plate, and connecting holes form an assembly structure that can be assembled into a modular expandable structure, providing support for multiple guide mechanisms. A wire guiding structure composed of a wire frame, limiting plate, and cover plate guides the wire harness and limits it within the positioning mechanism. A sliding rod, limiting rod, and return spring form a structure to limit the cover plate when it is closed. A nut sleeve, screw, and adjusting head form a structure to adjust the internal pressure of the guide component, allowing for better stability in limiting wire harnesses of different shapes by changing the internal pressure. This is an expandable modular splicing structure for wire harness installation. Through a positioning mechanism, the flow guiding component can be combined with a guiding component, clamping component, guide component, and wire fixing component to form an adaptive installation structure for wire harnesses. It can adaptively limit movement as the shape of the wire harness changes, increasing stability during installation. A pneumatic guiding structure composed of a flow divider, flow guiding holes, and inlet holes allows the air pressure inside the clamping component to communicate with the guide component, thus changing the air pressure inside the clamping component simultaneously with changes in the air pressure inside the guide component. A guiding structure composed of a limiting cylinder, buffer groove, and guide groove guides the direction of deformation of the clamping component due to internal air pressure changes. The wire harness clamping structure, composed of a one-way airbag, corrugated section, and contact plate, can work in conjunction with the wire fixing assembly to clamp the wire harness. It clamps the wire harness in a corrugated shape, increasing stability during installation. The guide structure, composed of an expanded airbag, cross-groove frame, and guide port, guides the displacement of the wire fixing assembly. It also changes its internal air pressure as the assembly moves, thereby altering the air pressure within the one-way airbag via a flow guide assembly, thus clamping the wire harness. The wire harness limiting structure, composed of a pressing plate, guide plate, and push plate, works in conjunction with the clamping assembly to clamp the wire harness. It can adapt to wire harnesses of different shapes and adjust the air pressure within the expanded airbag. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1 Please see Figures 1-5 An expandable modular splicing structure for wire harness installation includes a guide mechanism 1. The guide mechanism 1 includes a splicing component 11, an adjusting component 12, a fixing component 13, and a limiting component 14. The adjusting component 12 is located on top of the splicing component 11, the fixing component 13 is located on the front side of the top of the adjusting component 12, and the limiting component 14 is located on top of the adjusting component 12. By setting the guide mechanism 1, the wire harness installation limiting structure composed of the splicing component 11, the adjusting component 12, the fixing component 13, and the limiting component 14 can be spliced ​​with multiple guide mechanisms 1 to achieve modular expansion. The splicing structure is formed by the mounting base plate 111, the splicing plate 112, and the connecting holes 113. They can be assembled into a modular and expandable structure to support multiple guide mechanisms 1. The wire guide structure composed of wire frame 121, limiting plate 122 and cover plate 123 can guide the wire harness and limit the wire harness within the positioning mechanism 2. The slide rod 131 can form a structure to limit the cover plate 123 with the limiting rod 132 and the return spring 133, which can limit the cover plate 123 when it is closed. The nut sleeve 141 can form a structure to adjust the internal pressure of the guide assembly 24 with the screw 142 and the adjusting head 143, which can further adapt to the stability of limiting wire harnesses of different shapes by changing the internal pressure of the guide assembly 24.

[0031] The splicing assembly 11 includes a mounting base plate 111, an assembly plate 112, and connecting holes 113. The assembly plate 112 is bolted to the front and rear sides of the inner side of the mounting base plate 111. The connecting holes 113 are formed on the surface of the assembly plate 112. By setting the splicing assembly 11, the mounting base plate 111, the assembly plate 112, and the connecting holes 113 form an assembly structure that can be assembled into a modular and expandable structure, thereby providing support for multiple guide mechanisms 1. The mounting base plate 111 provides support for the assembly plate 112, allowing the mounting base plate 111 to be installed at the required position by external bolts. The assembly plate 112 can be connected to the connecting holes 113 on another set of splicing assemblies 11 by bolts through the connecting holes 113, forming a modular expansion connection.

[0032] The adjustment assembly 12 includes a wire frame 121, a limiting plate 122, and a cover plate 123. The wire frame 121 is bolted to both sides of the mounting base plate 111, the limiting plate 122 is bolted to the bottom of the inner side of the wire frame 121, and the cover plate 123 is rotatably connected between the opposite sides of the wire frame 121. By setting the adjustment assembly 12, the wire guide structure composed of the wire frame 121, the limiting plate 122, and the cover plate 123 can guide the wire harness and limit the wire harness within the positioning mechanism 2. The wire harness limiting and guiding structure composed of the wire frame 121 and the limiting plate 122 can provide guidance on both sides when the wire harness is installed in the positioning mechanism 2, and the cover plate 123 can limit the wire harness within the positioning mechanism 2.

[0033] The fixing component 13 includes a slide rod 131, a limiting rod 132, and a return spring 133. The slide rod 131 is slidably connected to the front side of the top of the guide frame 121. The limiting rod 132 is welded to the opposite side of the slide rod 131. The return spring 133 is installed on the inner side of the front side of the top of the guide frame 121. The opposite side of the return spring 133 contacts both sides of the slide rod 131. By setting the fixing component 13, the slide rod 131, the limiting rod 132, and the return spring 133 can form a structure to limit the cover plate 123. It can limit the cover plate 123 when it is closed. By pulling the limiting rod 132 to both sides, the slide rod 131 can be moved within the guide frame 121, allowing the slide rod 131 to be temporarily removed from the cover plate 123. When it is necessary to limit the cover plate 123, the return spring 133 uses its own elasticity to push the limiting rod 132, thereby limiting the slide rod 131 to the cover plate 123.

[0034] The limiting component 14 includes a nut sleeve 141, a screw 142, and an adjusting head 143. The nut sleeve 141 is welded to the top of the cover plate 123, the screw 142 is threaded to the inside of the nut sleeve 141, and the adjusting head 143 is welded to the top of the screw 142. By setting the limiting component 14, the nut sleeve 141, the screw 142, and the adjusting head 143 can form a structure for adjusting the internal pressure of the guide component 24. By changing the internal pressure of the guide component 24, the stability of limiting wire harnesses of different shapes can be further adapted. By limiting the screw 142 with the nut sleeve 141, the user can rotate the adjusting head 143 to drive the screw 142 to rotate, allowing the screw 142 to move up and down within the nut sleeve 141, thereby maintaining the current position after changing the pressure of the guide component 24.

[0035] The working principle of this embodiment is as follows: First, the wire harness is placed on the limiting plate 122 along the wire frame 121. Then, the wire harness is laid on the limiting plate 122 at the other end along the positioning mechanism 2. Then, the cover plate 123 is closed. At this time, the limiting rod 132 is pulled to both sides. The limiting rod 132 will drive the sliding rod 131 to move away from the cover plate 123. When the cover plate 123 is closed on the mounting base plate 111, the limiting rod 132 is released. The return spring 133 will use its elasticity to reset the sliding rod 131. The sliding rod 131 will limit the cover plate 123 to complete the installation of the wire harness. Then, other guide mechanisms 1 that need to be expanded and assembled with the wire harness are put into contact with the current guide mechanism 1 until each connecting hole 113 corresponds to each other. Then, the connecting holes 113 are connected to each other with bolts to complete the assembly. Finally, the assembled guide mechanism 1 is installed at the position where the current wire harness needs to be installed through the mounting base plate 111.

[0036] Example 2 refer to Figures 6-8An expandable modular splicing structure for wire harness installation also includes a positioning mechanism 2. The positioning mechanism 2 includes a flow guiding component 21, a guiding component 22, a clamping component 23, a guiding component 24, and a wire fixing component 25. The flow guiding component 21 is located on top of the splicing component 11. The guiding component 22 is located on the front and rear sides of the top of the flow guiding component 21. The clamping component 23 is located inside the guiding component 22. The guiding component 24 is located on top of the flow guiding component 21. The wire fixing component 25 is located on the surface of the guiding component 24. The positioning mechanism is used to... Structure 2: The flow guiding component 21, together with the guiding component 22, clamping component 23, guiding component 24, and wire fixing component 25, forms an adaptive installation structure for wire harnesses. It can adaptively limit movement as the shape of the wire harness changes, increasing stability during installation. Through the air pressure guiding structure formed by the diverter plate 211, the flow guiding hole 212, and the inlet hole 213, the air pressure inside the clamping component 23 can be interconnected with the guiding component 24. This allows for changes in air pressure within the clamping component 23 simultaneously with changes in air pressure within the guiding component 24. The air pressure, through the guiding structure composed of the limiting cylinder 221, buffer groove 222, and guide groove 223, can guide the deformation direction of the clamping assembly 23 caused by internal air pressure changes. The wire harness clamping structure composed of the one-way airbag 231, corrugated pipe section 232, and contact plate 233 can cooperate with the wire fixing assembly 25 to clamp the wire harness, simultaneously clamping it in a corrugated shape to increase stability during installation. The expanding airbag 241 and the cross-groove frame 24... The guiding structure composed of 2 and guide port 243 can guide the displacement of the wire fixing assembly 25. At the same time, it can change the internal air pressure of the wire fixing assembly 25 as it moves, thereby changing the air pressure in the one-way airbag 231 through the flow guiding assembly 21 to achieve clamping of the wire harness. The wire harness limiting structure composed of pressing plate 251, guide plate 252 and push plate 253 can cooperate with clamping assembly 23 to clamp the wire harness. It can also adapt to wire harnesses of different shapes and change the air pressure in the expansion airbag 241.

[0037] The flow guiding component 21 includes a flow divider plate 211, a flow guiding hole 212, and an inlet hole 213. The flow divider plate 211 is bolted to the top of the inner side of the mounting base plate 111. The flow guiding hole 212 is opened on the front and rear sides of the top of the flow divider plate 211, and the inlet hole 213 is opened on the top of the flow divider plate 211. By setting the flow guiding component 21, the air pressure guiding structure formed by the flow divider plate 211, the flow guiding hole 212, and the inlet hole 213 can connect the air pressure in the clamping component 23 with the guiding component 24. Thus, the air pressure in the clamping component 23 can be changed at the same time as the air pressure in the guiding component 24 changes. Through the cavity of the flow divider plate 211 itself, the air pressure in the guiding component 22 and the guiding component 24 can be interconnected through the flow guiding hole 212 and the inlet hole 213, which facilitates the subsequent adaptation to wire harnesses of different shapes.

[0038] The guide component 22 includes a limiting cylinder 221, a buffer groove 222, and a guide groove 223. The limiting cylinder 221 is connected to the top of the guide hole 212. The buffer groove 222 is opened on the inner side of the limiting cylinder 221, and the guide groove 223 is opened on the opposite side of the inner side of the limiting cylinder 221. By setting the guide component 22, the limiting cylinder 221, the buffer groove 222, and the guide groove 223 form a guide structure for the movement of the clamping component 23. This structure can guide the deformation direction of the clamping component 23 due to changes in internal air pressure. Since the limiting cylinder 221 is cylindrical, it can adapt to the shape of the clamping component 23. The guide groove 223 can guide the deformation direction of the clamping component 23, guiding its position relative to the guide component 24. The buffer groove 222 can provide a buffer space for the deformation of the clamping component 23 when it is squeezed after contacting the wire harness, preventing it from rupturing due to unstable internal air pressure.

[0039] The clamping assembly 23 includes a one-way airbag 231, a corrugated pipe section 232, and a contact plate 233. The one-way airbag 231 is connected to the top of the guide hole 212, the corrugated pipe section 232 is connected to the opposite side of the one-way airbag 231, and the contact plate 233 is installed on the opposite side of the corrugated pipe section 232. By setting the clamping assembly 23, the wire harness clamping structure formed by the one-way airbag 231, the corrugated pipe section 232, and the contact plate 233 can cooperate with the wire fixing assembly 25 to clamp the wire harness. At the same time, the wire harness is clamped in a corrugated shape, which increases the stability of the wire harness during installation. When the air pressure inside the one-way airbag 231 increases, the air pressure can be delivered to the corrugated pipe section 232. Under the guidance of the guide groove 223, the corrugated pipe section 232 can drive the contact plate 233 to move towards the wire harness, thereby clamping the wire harness.

[0040] The guide assembly 24 includes an expansion airbag 241, a cross-groove frame 242, and a guide port 243. The expansion airbag 241 is connected to the top of the inlet hole 213. The cross-groove frame 242 is bolted to the top of the diverter plate 211. The guide port 243 is located on the top of the cross-groove frame 242. The expansion airbag 241 is located inside the cross-groove frame 242. By setting the guide assembly 24, the guide structure formed by the expansion airbag 241, the cross-groove frame 242, and the guide port 243 can guide the displacement of the fixed assembly 25. At the same time, it can change its internal air pressure as the fixed assembly 25 moves, thereby changing the unidirectional flow through the guide assembly 21. The air pressure inside the airbag 231 clamps the wire harness. The wire harness pushes the wire fixing assembly 25 along the cross groove frame 242 toward the expanding airbag 241, which changes the air pressure inside the expanding airbag 241. This changes the air pressure inside the one-way airbag 231 through the flow guiding assembly 21, thus allowing the clamping assembly 23 to clamp the wire harness. Furthermore, the guide port 243 allows the screw 142 to extend, further compressing the expanding airbag 241. This further increases the air pressure inside the expanding airbag 241, the flow guiding assembly 21, and the one-way airbag 231, thereby further increasing the stability of the wire harness clamping.

[0041] The wire securing assembly 25 includes a pressing plate 251, a guide plate 252, and a push plate 253. The pressing plate 251 is disposed on the surface of the expansion airbag 241. The guide plate 252 is welded to the side of the pressing plate 251 away from the expansion airbag 241, and the surface of the guide plate 252 is slidably connected to the inner side of the cross-groove frame 242. The push plate 253 is welded to the side of the guide plate 252 away from the expansion airbag 241. By setting the wire securing assembly 25, the wire harness limiting structure formed by the pressing plate 251, the guide plate 252, and the push plate 253 can cooperate with the clamping assembly 23 to clamp the wire harness. It can hold and adapt to wire harnesses of different shapes, and change the air pressure in the expansion airbag 241. Through the I-shaped structure formed by the pressing plate 251, the guide plate 252 and the push plate 253, after the push plate 253 contacts the wire harness, the guide plate 252 drives the pressing plate 251 to squeeze the expansion airbag 241 along the cross groove frame 242, thereby changing the air pressure in the expansion airbag 241. At the same time, after the air pressure in the expansion airbag 241, the flow guiding component 21 and the one-way airbag 231 is balanced, it adapts to the shape of the wire harness, realizes the clamping of the wire harness, and completes the installation of the wire harness.

[0042] The working principle of this embodiment is as follows: When the wire harness is installed in the positioning mechanism 2, the wire harness first contacts the push plate 253. The push plate 253 is squeezed to adapt to the shape of the wire harness. It waits for other components to fill the expansion airbag 241, which then pushes the push plate 253 to limit the wire harness. The guide plate 252 pushes the pressing plate 251 along the cross-groove frame 242 towards the expansion airbag 241, thereby squeezing the expansion airbag 241. The air pressure inside the expansion airbag 241 enters the diverter plate 211 through the inlet hole 213, and then flows into the one-way airbag 231 through the guide hole 212. The one-way airbag 231 expands as the air pressure increases, causing the corrugated section 232 to expand. The expansion will cause the wire harness to deform along the guide groove 223, while simultaneously moving the contact plate 233 toward the wire harness. The contact plate 233 and the push plate 253 will clamp the wire harness together, causing the wire harness to gradually form a wave shape. When it is necessary to further increase the installation stability of the wire harness, the user can rotate the adjustment head 143, causing the adjustment head 143 to drive the screw 142 to move downward along the nut sleeve 141. The screw 142 will push the expansion airbag 241 downward along the guide port 243, further increasing the air pressure in the expansion airbag 241, the flow guide component 21 and the one-way airbag 231, thereby causing the push plate 253 and the contact plate 233 to be further pushed to clamp the wire harness.
