[0050] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0051] Embodiment 1

[0052] like Figure 1-Figure 10As shown, in this embodiment, a controller harness anti-detachment structure is provided, including an inner fixing plate 1, which is fixed on the front side wall of the controller, and the inner fixing plate 1 penetrates the front side wall along the thickness direction of the front side wall and extends to the outside; a center hole 101 is opened in the center of the inner fixing plate 1 for passing the harness in the controller out; a plurality of wire clamping grooves 102 are evenly distributed on the side wall of the center hole 101 in a circumferential direction; a center block 2 is inserted into the center of the center hole 101; a slider 3 is slidably connected to the inside of the center block 2 through a first spring 4, and the center block 2 There are multiple clamping blocks 5 distributed circumferentially. When the center block 2 is installed in the center hole 101, the multiple clamping blocks 5 correspond to the multiple wire clamping grooves 102 one by one. A push rod 6 is arranged between each clamping block 5 and the slider 3. One end of the push rod 6 is hinged to the slider 3, and the other end of the push rod 6 is hinged to the connecting block 501 on the clamping block 5. One end of the push rod 6 hinged to the connecting block 501 is lower than the end hinged to the slider 3. When the slider 3 slides downward in the center block 2, the push rod 6 presses the clamping block 5 to slide toward the corresponding wire clamping groove 102.

[0053] Wire clamping process: fix the inner fixing plate 1 on the front side wall of the controller, then pass each wire harness through the center hole 101, and place each wire harness one by one in the wire clamping groove 102, and then put the center block 2 into the center hole 101. At this time, the multiple clamping blocks 5 on the center block 2 correspond to the wire clamping groove 102 one by one, that is, each clamping block 5 faces a wire clamping groove 102 at one end away from the center block 2. Press the slider 3 downward, and the slider 3 presses the clamping block 5 through the push rod 6, causing the clamping block 5 to slide toward the corresponding wire clamping groove 102. At this time, the end of the clamping block 5 presses the wire harness in the wire clamping groove 102. Through the cooperation of the clamping block 5 and the wire clamping groove 102, the wire harness is firmly fixed inside the controller, effectively preventing the risk of the wire harness falling off due to vibration or external force.

[0054] The anti-drop structure can make the installation and removal of the wire harness very simple, and the wire harness can be easily fixed and released simply by pressing or releasing the slider 3.

[0055] An outer fixing plate 15 is provided on the front side wall of the controller, and the outer fixing plate 15 is sleeved on the inner fixing plate 1. A plurality of bolts are provided on the outer fixing plate 15, and the threaded ends of the plurality of bolts sequentially penetrate the outer fixing plate 15, the front side wall of the controller and the inner fixing plate 1, and mesh with the inner fixing plate 1, so that the outer fixing plate 15 and the inner fixing plate 1 are fixed by bolts, and a top fixing plate 16 for crimping the slider 3 is provided on the outer end surface of the inner fixing plate 1, and a plurality of make way grooves 1601 are provided on the side wall of the top fixing plate 16, and a hollow nut 17 for fixing the top fixing plate 16 on the outer wall of the inner fixing plate 1 is meshed on the outer fixing plate 15, and the outer side of the hollow nut 17 is evenly distributed with anti-slip patterns.

[0056] When the center block 2 is placed into the center hole 101, the top fixing plate 16 is placed on the outer end face of the inner fixing plate 1, and the wiring harness in the wire clamping groove 102 corresponds one by one to the inside of the make way groove 1601. At this time, the hollow nut 17 is sleeved on the outer fixing plate 15, and the hollow nut 17 is pressed on the side of the top fixing plate 16. As the hollow nut 17 rotates to feed the wire, the top fixing plate 16 is continuously crimped toward the outer end face of the inner fixing plate 1 by the hollow nut 17. Finally, the top fixing plate 16 fixes the slider 3 in the crimped state, and the wiring harness is fixed at this time.

[0057] Embodiment 2

[0058] like Figure 3-Figure 5 as well as Figure 8 As shown, on the basis of the first embodiment, in order to firmly clamp the wire harness in the wire clamping groove 102 and further prevent the wire harness from falling off, each wire clamping groove 102 includes an upper clamping groove 1021 and a lower clamping groove 1022, and the groove walls of the upper clamping groove 1021 and the lower clamping groove 1022 relative to the center hole 101 are vertically arranged, and the distance between the groove wall of the upper clamping groove 1021 relative to the center hole 101 and the center hole 101 is greater than the distance between the lower clamping groove 1022 and the center hole The distance between a groove wall of 101 and the center hole 101 is such that a horizontal platform 1023 is formed between the upper groove 1021 and the lower groove 1022; wherein, the upper and lower parts of the clamping block 5 are respectively clamped on the upper groove 1021 and the lower groove 1022, and the upper part of the corresponding clamping block 5 is longer than the lower part of the clamping block 5. When the slider 3 slides downward, the upper part of the clamping block 5 and the lower part of the clamping block 5 are simultaneously clamped on the upper groove 1021 and the lower groove 1022.

[0059] like Figure 8 As shown, during the process of placing the center block 2 in the center hole 101, affected by the length of the upper part of the clamping block 5, the wiring harness corresponding to the upper slot 1021 will bend toward the upper slot 1021. When the upper part of the clamping block 5 and the lower part of the clamping block 5 are simultaneously clamped on the upper slot 1021 and the lower slot 1022, the wiring harness inside the wire clamping slot 102 will be clamped to the upper slot 1021 and the lower slot 1022 by the clamping block 5. At the same time, the wiring harness between the upper slot 1021 and the lower slot 1022 will be placed horizontally on the horizontal platform 1023 to form a Z-shaped fixed structure.

[0060] Through the coordinated action of the upper clamping groove 1021 , the lower clamping groove 1022 and the abutting block 5 , the wire harness is firmly clamped in the wire clamping groove 102 , effectively preventing the wire harness from falling off.

[0061] The Z-shaped fixing structure further enhances the stability of the wire harness and maintains a good fixing effect even in harsh environments such as vibration or impact.

[0062] Embodiment 3

[0063] like Figure 4-Figure 9 As shown, on the basis of the second embodiment, this embodiment not only helps to prevent the wiring harness from escaping from the upper slot 1021, but also provides an additional sealing effect to prevent the intrusion of foreign substances such as moisture and dust. A first sealing gasket 7 is arranged inside the upper slot 1021, and a second sealing gasket 8 is arranged on the upper part of the clamping block 5; when the upper part of the clamping block 5 is pressed against the wiring harness in the upper slot 1021, the first sealing gasket 7 and the second sealing gasket 8 are wrapped around the side wall of the wiring harness in a ring shape; a third sealing gasket 9 is arranged inside the lower slot 1022, and a fourth sealing gasket 10 is arranged at the lower part of the clamping block 5; when the lower part of the clamping block 5 is pressed against the wiring harness in the lower slot 1022, the third sealing gasket 9 and the fourth sealing gasket 10 are wrapped around the side wall of the wiring harness in a ring shape.

[0064] Upper card slot 1021 and first and second sealing gaskets:

[0065] When the pressing block 5 is operated to press against the wire harness in the upper slot 1021, the first sealing pad 7 and the second sealing pad 8 work together to form a ring shape wrapped around the side wall of the wire harness, which not only helps to prevent the wire harness from escaping from the upper slot 1021, but also provides an additional sealing effect to prevent the intrusion of foreign substances such as moisture and dust.

[0066] Lower card slot 1022 and third and fourth sealing gaskets:

[0067] Similarly, when the lower part of the abutting block 5 abuts against the wire harness in the lower slot 1022, the third sealing pad 9 and the fourth sealing pad 10 also form a ring shape and wrap around the side wall of the wire harness, which further enhances the fixation and sealing of the wire harness in the lower slot 1022.

[0068] Overall anti-slip and sealing effect:

[0069] By arranging sealing pads on the upper and lower clamping grooves and the abutting block 5 respectively, the structure can provide fixation and sealing protection for the wiring harness at multiple levels.

[0070] This design not only effectively prevents the wiring harness from loosening and falling off, but also greatly improves the overall sealing performance, helping to extend the service life of the wiring harness and the entire controller.

[0071] A plurality of protrusions 11 with arc-shaped cross sections are provided on the side walls of the first sealing gasket 7 and the second sealing gasket 8 that are in close contact with the wiring harness.

[0072] Arc shape protrusion 11:

[0073] The arc-shaped protrusion 11 can fit the outer surface of the wiring harness more closely, increase the contact area and friction between the sealing pad and the wiring harness, and thus more effectively prevent the wiring harness from loosening and falling off.

[0074] At the same time, the arc-shaped protrusion 11 can also provide a certain elastic buffering effect, reducing the impact and wear of the wiring harness when it is subjected to external forces.

[0075] The side of the horizontal platform 1023 away from the center hole 101 is inclined downward, and the connecting block 501 is slidably connected to the clamping block 5 through the second spring 13; a pressure plate 14 is also provided inside the clamping block 5, and the pressure plate 14 is rotatably connected to the clamping block 5, and is used to press the wiring harness onto the horizontal platform 1023; wherein, a pushing block 502 is fixedly connected to the side wall of the connecting block 501, and a guide groove 1401 is opened on the side wall of the pressure plate 14, and the lower end of the pushing block 502 is slidably connected to the inside of the guide groove 1401.

[0076] The entire harness crimping process is:

[0077] When the slider 3 is slid downward, the push rod 6 pushes the abutment block 5 through the connecting block 501 to move in a certain direction. Figure 8 When sliding in the direction of the arrow shown, first, under the pressure of the second spring 13, the connecting block 501 slides synchronously with the clamping block 5. At this time, the end line of the clamping block 5 presses the wiring harness against the inside of the upper groove 1021 and the lower groove 1022. Since the side of the horizontal platform 1023 away from the center hole 101 is tilted downward, there is a gap between the wiring harness above the horizontal platform 1023 and the horizontal platform 1023. Then, after continuing to slide the slider 3, the connecting block 501 compresses the second spring 13 to slide, and the lower end of the pushing block 502 slides along the guide groove 1401. Therefore, with the cooperation of the pushing block 502 and the guide groove 1401, the pressure plate 14 rotates downward, and then presses the wiring harness onto the horizontal platform 1023.

[0078] Since the pressing point of the pressure plate 14 on the wire harness is concentrated at the connection position between the upper slot 1021 and the horizontal platform 1023, when the pressure plate 14 presses the wire harness, the wire harness in the upper slot 1021 will be pressed downward by the pressure plate 14, causing the wire harness to generate a downward force on the first and second sealing pads. The first and second sealing pads are deformed by the force, so that they can fit more closely to the outer surface of the wire harness, increasing the contact area and friction between the sealing pad and the wire harness, thereby more effectively preventing the wire harness from loosening and falling off.

[0079] A cavity is disposed inside the first sealing gasket 7 and the second sealing gasket 8 . A plurality of spacer plates 12 are evenly disposed in the cavity in a transverse direction. The spacer plates 12 are inclined upward at a side close to the protrusion 11 .

[0080] Cavity and spacer 12:

[0081] A plurality of partition plates 12 are evenly arranged in the cavity in a transverse direction, and the partition plates 12 divide the cavity into a plurality of small chambers.

[0082] The presence of the spacer plate 12 enhances the structural strength of the sealing gasket, enabling it to maintain better shape stability and anti-deformation capability when facing external forces.

[0083] In addition, since the side of the spacer 12 close to the protrusion 11 is inclined upward, when the wiring harness in the upper slot 1021 is displaced downward, the cavity can also enable the first and second sealing pads to deform better, and the side of the spacer 12 close to the protrusion 11 will tilt downward toward a horizontal state. At this time, the spacer 12 can exert a certain top pressure on the protrusion 11, so that it can fit more closely to the outer surface of the wiring harness, increase the contact area and friction between the sealing pad and the wiring harness, and thus more effectively prevent the wiring harness from loosening and falling off.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
