DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, and provides a sealing mechanism, including a clamping assembly 100, including a first clamping plate 101, a second clamping plate 102 opposite to the first clamping plate 101, and a fixing frame 103 arranged around the first clamping plate 101 and the second clamping plate 102;

[0035] The airbag assembly 300 includes a harness airbag 301 disposed between the first clamping plate 101 and the second clamping plate 102 , and a top cover airbag 302 disposed on one side of the first clamping plate 101 and the second clamping plate 102 close to the pressing block 204 .

[0036] Furthermore, one side of the first clamping plate 101 is provided with an array of positioning pins 101a, the first clamping plate 101 is provided with first clamping inclined surfaces 101b on both sides of the side opposite to the positioning pins 101a, and the first clamping plate 101 is provided with a first notch 101c on one side close to the positioning pins 101a.

[0037] Furthermore, a positioning hole 102a is formed on one side of the second clamping plate 102 opposite to the positioning pin 101a, second clamping inclined surfaces 102b are formed on both sides of the second clamping plate 102 opposite to the positioning hole 102a, and a second notch 102c is formed on one side of the second clamping plate 102 close to the positioning hole 102a.

[0038] It should be noted that the fixing frame 103 is a square embedded structure, and its size is adapted to the wire harness slot that needs to be sealed. The fixing frame 103 can sink into the slot and fit with the side wall of the slot. The four sides of the fixing frame 103 are arranged with push block slots 103a in an array, and the push block slots 103a are arranged with a ball hole 103a-1 at one end facing the slot. The push block slots 103a at both ends of the opposite sides of the fixing frame 103, away from the ball hole 103a-1, penetrate the fixing frame 103a to the inside, and are the transmission slots 103a-2 for the push block 201 to move to the inside through the push block slots 103a.

[0039] A baffle 103b parallel to the fixing frame 103 is arranged in the fixing frame 103, and the baffle 103b can limit the positions of the first clamping plate 101 and the second clamping plate 102, so that the first clamping plate 101 and the second clamping plate 102 can only translate along the fixing frame 103 and will not fall off.

[0040] Preferably, the first clamping plate 101 is provided with a first notch 101c, and the second clamping plate 102 is provided with a second notch 102c. The first notch 101c and the second notch 102c can form a harness hole 104, and the harness hole 104 can allow the harness to pass through and connect the inverter part and the high-voltage box. The inner side of the first clamping plate 101 is provided with a positioning pin 101a, and the inner side of the second clamping plate 102 is provided with a positioning hole 102a.

[0041] Further, the positioning pin 101a includes a receiving groove 101a-1 disposed at its end, a ball rod 101a-2 symmetrically disposed on the side wall of the receiving groove 101a-1, a reset block 101a-3 disposed between the ball rod 101a-2, and a reset spring 101a-4 disposed between the reset block 101a-3 and the bottom of the receiving groove 101a-1;

[0042] The positioning hole 102a includes an extrusion groove 102a-1 arranged at an end thereof, a sliding key 102a-2 symmetrically arranged in the extrusion groove 102a-1, and a clamping groove 102a-3 radially arranged in the extrusion groove 102a-1.

[0043] Preferably, a countersunk hole is provided deep in the accommodating groove 101a-1 to cooperate with the reset block 101a-3, so that the reset block 101a-3 can be completely pressed into the accommodating groove 101a-1, and the cross-section of the reset block 101a-3 is an isosceles trapezoid. The angle of the inclined surface at the end of the ball rod 101a-2 away from the ball head is the same as the angle of the waist of the cross-section of the reset block 101a-3, and the distance that the ball head of the ball rod 101a-2 extends out of the side wall of the positioning pin 101a is less than the radius of the ball head, ensuring that the ball head can be extended but cannot fall off.

[0044] When the first clamping plate 101 and the second clamping plate 102 move toward each other, the positioning pin 101a is aligned with the positioning hole 102a, and the ball rod 101a-2 in the receiving groove 101a-1 at the end of the positioning pin 101a is first squeezed by the side wall of the positioning hole 102a. The first clamping plate 101 and the second clamping plate 102 continue to move, and the ball rod 101a-2 will retract inward and squeeze the reset block 101a-3, and the reset block 101a-3 squeezes the reset spring 101a-4. At the same time, the ball rod 101a-2 pushes the sliding key 102a-2 toward the second clamping plate 102, and the sliding key 102a-2 acts on the squeezing groove 102a-1. The ball rod 101a-2 is tightened inward along the arc curve of the extrusion groove 102a-1 and approaches the inclined surface of the reset block 101a-3 until the ball rod 101a-2 is also tightened toward the middle along the arc curve of the extrusion groove 102a-1 and is stuck in the slot 102a-3 opened on the extrusion groove 102a-1. At this time, the first notch 101c of the first clamp plate 101 and the second notch 102c of the second clamp plate 102 just form a complete wiring harness hole 104, and the wiring harness airbag 301 surrounding the wiring harness hole 104 is squeezed and deformed by the wiring harness and the wiring harness hole 104, filling the gap of the wiring harness hole 104, thereby achieving the sealing of the wiring harness hole 104.

[0045] Preferably, the material of the wire harness airbag 301 and the top cover airbag 302 is polyester fiber, and the inside of the airbag is filled with nitrogen.

[0046] In summary, this design uses the separation design of the splint to form a wiring harness hole when combined, and at the same time squeeze the airbag to seal the wiring harness hole, and at the same time clamp the clamping component to fix the wiring harness softly without damaging it. When replacement is needed, just deflate the airbag and the clamping component can be easily separated.

[0047] Example 2

[0048] Reference Figure 1 and Figure 4 , which is a second embodiment of the utility model, comprises a clamping assembly 100, including a first clamping plate 101, a second clamping plate 102 opposite to the first clamping plate 101, and a fixing frame 103 disposed around the first clamping plate 101 and the second clamping plate 102;

[0049] The resistance assembly 200 includes push blocks 201 disposed on both sides of the clamping assembly 100, a force spring 202 disposed on one side of the push block 201, a force ball 203 disposed on the side of the force spring 202 away from the push block 201, and a pressure block 204 disposed perpendicularly to the push block 201;

[0050] The airbag assembly 300 includes a harness airbag 301 disposed between the first clamping plate 101 and the second clamping plate 102 , and a top cover airbag 302 disposed on one side of the first clamping plate 101 and the second clamping plate 102 close to the pressing block 204 .

[0051] Furthermore, one side of the first clamping plate 101 is provided with an array of positioning pins 101a, and the first clamping plate 101 is provided with first clamping inclined surfaces 101b on both sides of the side opposite to the positioning pins 101a. The second clamping plate 102 is provided with a positioning hole 102a on the side opposite to the positioning pins 101a, and the second clamping inclined surfaces 102b are provided on both sides of the side opposite to the positioning hole 102a.

[0052] Furthermore, a push block groove 103 a is arranged in an array inside the fixing frame 103 , and a baffle 103 b is arranged on the inner side of the fixing frame 103 close to the clamping assembly 100 .

[0053] Furthermore, a ball hole 103a-1 is provided at one end of the push block groove 103a, and a transmission groove 103a-2 is provided at the push block groove 103a near the first clamping inclined surface 101b and the second clamping inclined surface 102b.

[0054] Furthermore, the push block 201 includes a spring groove 201a disposed at one end thereof, an inner push inclined surface 201b disposed at an end opposite to the spring groove 201a, and a pressing inclined surface 201c disposed at one end of the inner push inclined surface 201b.

[0055] Furthermore, the top cover airbag 302 surrounds the fixing frame 103 .

[0056] It should be noted that the first clamping plate 101 and the second clamping plate 102 are rectangular as a whole, and the four corners of the rectangle formed by the first clamping plate 101 and the second clamping plate 102 are respectively cut with the first clamping bevel 101b and the second clamping bevel 102b, and the end of the push block groove 103a close to the first clamping bevel 101b and the second clamping bevel 102b away from the ball mouth 103a-1 passes through the interior of the fixed frame 103, so that the push block 201 can pass through the transmission groove 103a-2.

[0057] Preferably, a force spring 202 is provided at one end of the push block 201 close to the ball opening 103a - 1 , one end of the force spring 202 abuts in the spring slot 201a of the push block 201 , and the other end abuts on the force ball 203 .

[0058] Preferably, one end of the force-bearing ball 203 extends out of the ball opening 103a-1, and the circumference of the ball opening 103a-1 is smaller than the diameter of the force-bearing ball 203, ensuring that the force-bearing ball 203 will not pop out along the ball opening 103a-1, while the force-bearing ball 203 can be pressed against the ball opening 103a-1 by the force-bearing spring 202.

[0059] Preferably, an inward push bevel 201b is provided at one end of the push block 201 away from the force spring 202, and the angle of the inward push bevel 201b is the same as the angle of the first clamping bevel 101b and the second clamping bevel 102b, that is, the inward push bevel 201b is parallel to the first clamping bevel 101b, and the inward push bevel 201b is also parallel to the second clamping bevel 102b. When the push block 201 moves away from the ball mouth 103a-1, the inward push bevel 201b can push the first clamping bevel 101b and the second clamping bevel 102b to cause the first clamping plate 101 and the second clamping plate 102 to approach the wiring harness to form the wiring harness hole 104, and the strokes of the first clamping plate 101 and the second clamping plate 102 are equal.

[0060] Preferably, the push block 201 is further provided with a pressing slope 201c at one end close to the inner push slope 201b, and the pressing slope 201c is parallel to the slope provided on the pressing block 204, that is, when the push block 201 moves, it can push the first clamping plate 101 and the second clamping plate 102 to move, and can also push the pressing block 204 to move.

[0061] Preferably, a top cover airbag 302 is provided on the side of the fixing frame 103 facing the pressing block 204, and the top cover airbag 302 can be pressed by the pressing block 204, and the top cover airbag 302 will be deformed and block the gap between the fixing frame 103 and the wire harness slot. At the same time, because the top cover airbag 302 is deformed, the internal pressure increases, which will have a reaction force on the pressing block 204, and then give the push block 201 a force to move toward the ball port 103a-1. The force spring 202 applies pressure to the force-bearing ball 203, and the force-bearing ball 203 is tightly pressed against the ball slot opened on the side wall of the wire harness slot, thereby enhancing the firmness of the top cover. If the top cover needs to be disassembled, it is only necessary to deflate the airbag, and the pressure of the airbag on the pressing block 204 is reduced, and the maintenance personnel can easily remove the top cover.

[0062] Example 3

[0064] Furthermore, a handle 401 a is provided on a side of the sheet metal cover 401 away from the fixing frame 103 .

[0065] It should be noted that the sheet metal cover 401 is fixedly connected to the fixing frame 103 and is arranged on one side of the fixing frame 103. The sheet metal cover 401 and the baffle 103b on the fixing frame 103 jointly limit the first clamping plate 101 and the second clamping plate 102 to prevent the clamping plates from falling off. The sheet metal cover 401 is simultaneously provided with a completed hole larger than the wiring harness hole 104 at the wiring harness hole 104 formed after the first clamping plate 101 and the second clamping plate 102 are attached, which can improve the fault tolerance of wiring harness replacement.

[0066] Preferably, a handle 401a is provided on the side of the sheet metal cover 401 away from the fixing frame 103 to facilitate force application during assembly and disassembly.

[0067] Preferably, a sealing foam strip is further provided between the sheet metal cover 401 and the wiring harness notch to further seal the top cover and improve the sealing performance of the top cover.

[0068] In summary, this design retains the original foam strips to further improve the sealing of the wiring harness.
