Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harness installation, and in particular to a rubber sheath for a new energy automobile wiring harness. Background Art

[0002] The wiring harness of new energy vehicles is an important part of the electrical system of new energy vehicles. It is responsible for connecting and transmitting electrical energy and signal data between various electrical devices inside the vehicle to ensure the normal operation and performance of new energy vehicles. At present, rubber sheaths are used when the wiring harness of new energy vehicles passes through the sheet metal holes on the sheet metal parts to prevent the sheet metal parts from damaging the wiring harness. The general structure of the existing rubber sheath is: a round hole is opened in the middle of the rubber sheath to allow the wiring harness to pass through, and a sleeve or tail is designed on one or both sides of the through hole of the rubber sheath to facilitate the use of tape to bundle the wiring harness and the rubber sheath so that the rubber sheath and the wiring harness do not move relative to each other.

[0003] However, in actual use, especially when the vehicle is in a non-uniform speed state (such as when the vehicle is driving on a bumpy road or braking suddenly), or when the angle of the wire harness coming out of the sheath hole is large, since the sheath is fixed on the sheet metal, a certain impact force will be generated between the rubber sheath and the sheet metal hole on the sheet metal, thereby increasing the fatigue strength of the rubber sheath and reducing the life of the rubber sheath. At the same time, the tape fixing method is not reliable enough. Long-term or frequent impact will cause the tape to fail, resulting in the separation of the wire harness from the rubber sheath, the wire harness loses the protection of the rubber sheath, and even causes the wire harness to be separated from the wire hole due to excessive movement, which in turn affects the performance of the entire vehicle.

[0004] Therefore, the present invention provides a rubber sheath for a new energy vehicle wiring harness to solve the above problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a rubber sheath for new energy vehicle wiring harness to solve the problems that the above-mentioned existing rubber sheath has poor impact resistance and the wire harness is not firmly fixed by the tape.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] A rubber sheath for wiring harness of new energy vehicles, as shown in the following Figures 1 to 13 As shown, it comprises a rubber sleeve 1, wherein both the upper and lower parts of the rubber sleeve 1 are provided with an inner cylinder 2 in the upper and lower axial direction, a plurality of connecting rods 3 are provided between the two inner cylinders 2 and are evenly distributed along the circumferential direction of the rubber sleeve 1, a groove 4 corresponding to the inner cylinder 2 and the plurality of connecting rods 3 is provided on the rubber sleeve 1, an outer cylinder 5 in the upper and lower axial direction is sleeved on the two inner cylinders 2, a stopper 6 located between the two inner cylinders 2 is provided in the outer cylinder 5, a reset mechanism is provided between the stopper 6 and the two inner cylinders 2, a first stop ring 7 is provided on the upper part of the outer cylinder 5, a second stop ring 8 in the upper and lower axial direction is threadedly connected to the lower part of the outer cylinder 5, and a tightening mechanism is threadedly connected to the upper and lower inner cylinders 2;

[0037] The tightening mechanism includes an upper and lower axial ring 9, which is threadedly connected to the inner cylinder 2 on the corresponding side, and the lower ring 9 is vertically slidably connected to the second retaining ring 8. The front end of the ring 9 is rotatably connected to two upper and lower axial and left and right opposite rotating shafts 10, and the rotation directions of the two rotating shafts 10 are opposite. A winding wheel 11 is provided at one end of the rotating shaft 10, and a plurality of tightening grooves 12 that are evenly distributed along its circumferential direction and penetrate inside and outside are provided at both upper and lower ends of the rubber sleeve 1. An arc-shaped clamping block 13 is provided between every two tightening grooves 12 on the rubber sleeve 1, and an arc-shaped clamping groove 14 is provided on the arc-shaped clamping block 13. A pull rope 15 is provided between the two left and right opposite winding wheels 11, and the pull rope 15 can be rolled up on the winding wheel 11, and the pull rope 15 can be clamped in multiple arc-shaped clamping grooves 14 on the same side.

[0038] The reset mechanism includes a reset spring 16 in the upper and lower axial directions. The reset spring 16 always drives the stopper 6 to be close to the center between the two inner cylinders 2. When the outer cylinder 5 is subjected to an external force and slides up and down along the inner cylinder 2, the outer cylinder 5 drives the stopper 6 to squeeze the reset spring 16. After the external force disappears, the reset spring 16 returns to its initial length, and the reset spring 16 drives the stopper 6 to move to the center between the two inner cylinders 2.

[0039] As attached Figure 1 , Figure 6 and Figure 7 As shown, the upper end of the lower circular ring 9 is provided with a plurality of L-shaped rods 17 evenly distributed along its circumferential direction, the vertical portion of the L-shaped rod 17 is vertically slidingly connected to the second retaining ring 8, and the horizontal portion of the L-shaped rod 17 can prevent the lower circular ring 9 from being separated from the second retaining ring 8. When the lower circular ring 9 is moved up and down by external force, the circular ring 9 drives the plurality of L-shaped rods 17 to slide up and down along the second retaining ring 8, and the plurality of L-shaped rods 17 are used to realize a vertical sliding connection between the lower circular ring 9 and the second retaining ring 8 without contact.

[0040] As attached Figure 1 , Figure 6 , Figure 8 and Fig.11 As shown, a driven gear 18 is provided on the end of the rotating shaft 10 away from the winding wheel 11, and the two driven gears 18 are meshed with each other. When one of the rotating shafts 10 rotates, the other rotating shaft 10 will be driven to rotate in the opposite direction through the two driven gears 18, thereby achieving opposite rotation directions of the two rotating shafts 10.

[0041] As attached Figure 1 , Fig. 9 and Fig.10 As shown, the circular ring 9 is rotatably connected with a T-shaped shaft 19 located on the right side of the two rotating shafts 10 and in the upper and lower axial directions. The vertical portion of the T-shaped shaft 19 is provided with a driving gear 20, and the driving gear 20 is meshed with the driven gear 18 on the right side. The horizontal portion of the T-shaped shaft 19 is vertically slidably connected with a handwheel 21, and the end of the handwheel 21 can be stuck on the circular ring 9. When the handwheel 21 rotates, the handwheel 21 drives the T-shaped shaft 19 to rotate, the T-shaped shaft 19 drives the driving gear 20 to rotate, and the driving gear 20 drives the driven gear 18 to rotate, so that the staff can operate the two rotating shafts 10 to rotate conveniently.

[0042] As attached Fig. 9 , Fig.10 As shown, the vertical portion of the T-shaped shaft 19 is provided with a plurality of guide grooves 22 which are evenly distributed along its circumferential direction and penetrate vertically, and a plurality of guide rails 23 which correspond one-to-one to the guide grooves 22 and are in the vertical direction are provided in the handwheel 21, and the guide rails 23 are vertically slidably connected with the guide grooves 22 on the corresponding side. When the handwheel 21 slides up and down along the T-shaped shaft 19, the handwheel 21 drives the plurality of guide rails 23 to move up and down, and the guide rails 23 slide up and down along the guide grooves 22 on the corresponding side, thereby realizing the vertical sliding connection between the handwheel 21 and the horizontal portion of the T-shaped shaft 19, and the guide rails 23 and the guide grooves 22 can prevent relative rotation between the handwheel 21 and the T-shaped shaft 19.

[0043] As attached Fig.12 and Fig.13As shown, the handwheel 21 is provided with a plurality of limit blocks 25 evenly distributed along the circumferential direction of the T-shaped shaft 19, and the ring 9 is provided with a plurality of limit grooves 24 corresponding to the limit blocks 25 one by one. The limit blocks 25 can be inserted into the limit grooves 24 on the corresponding side, so that the end of the handwheel 21 can be clamped on the ring 9.

[0044] As attached Fig.10 As shown, the vertical portion of the T-shaped shaft 19 is provided with a compression spring 26 located between its horizontal portion and the hand wheel 21. The compression spring 26 always drives the hand wheel 21 to be close to the ring 9. When the staff pulls the hand wheel 21, the hand wheel 21 will squeeze the compression spring 26 between the horizontal portion of the T-shaped shaft 19. When the staff releases the hand wheel 21, the compression spring 26 returns to its initial length, and the compression spring 26 drives the hand wheel 21 back to its initial position.

[0045] As attached Figures 1 to 4 As shown, the upper and lower ends of the rubber sleeve 1 are both set to be L-shaped, and the end of the arc-shaped clamping block 13 is fixedly connected to the horizontal end of the rubber sleeve 1, and the arc-shaped clamping block 13 is prevented from separating from the rubber sleeve 1 by increasing the contact area between the arc-shaped clamping block 13 and the rubber sleeve 1.

[0046] When the present invention is in use, in the initial state, the second retaining ring 8 is threadedly connected to the outer cylinder 5, and the lower ring 9 is threadedly connected to the lower inner cylinder 2. The staff needs to rotate the second retaining ring 8 counterclockwise, and the second retaining ring 8 gradually separates from the lower inner cylinder 2. At the same time, the second retaining ring 8 drives the multiple L-shaped rods 17 to rotate counterclockwise, and the multiple L-shaped rods 17 jointly drive the lower ring 9 to rotate counterclockwise, and the lower ring 9 gradually separates from the lower inner cylinder 2. At this time, the staff can remove the second retaining ring 8 and the lower ring 9;

[0047] The staff passes the outer cylinder 5 through the sheet metal hole of the new energy vehicle, and makes the first retaining ring 7 contact with the end face of one end of the sheet metal, and the end with thread on the outer cylinder 5 is located at the other end of the sheet metal, so that the second retaining ring 8 contacts with the threaded end of the outer cylinder 5, and makes the lower ring 9 contact with the lower inner cylinder 2, and then rotates the second retaining ring 8 clockwise, and the second retaining ring 8 is gradually threadedly connected with the outer cylinder 5. At the same time, the second retaining ring 8 drives the multiple L-shaped rods 17 to rotate clockwise, and the multiple L-shaped rods 17 jointly drive the lower ring 9 to rotate clockwise, and the lower ring 9 is gradually threadedly connected with the lower inner cylinder 2. Continue to rotate the second retaining ring 8 clockwise until the end face of the second retaining ring 8 contacts the end face of the other end of the sheet metal. At this time, stop rotating the second retaining ring 8, the first retaining ring 7 and the second retaining ring 8 tighten the sheet metal, and the outer cylinder 5 is fixed on the sheet metal hole of the sheet metal;

[0048] The staff passes the wiring harness through the inside of the rubber sleeve 1, and after completing the connection of the corresponding circuit of the wiring harness, the pull rope 15 is clamped in the arc-shaped card slot 14 on the multiple arc-shaped card blocks 13. The staff first pulls the hand wheel 21, and the hand wheel 21 drives the multiple guide rails 23 to slide along the guide slot 22. At the same time, the hand wheel 21 drives the multiple limit blocks 25 to leave the limit slot 24 on the corresponding side. At this time, the hand wheel 21 can rotate freely. The staff needs to keep pulling the hand wheel 21 while turning the hand wheel 21 clockwise. The hand wheel 21 drives the T-shaped shaft 19 to rotate clockwise through the guide rail 23 and the guide slot 22. The T-shaped shaft 19 drives the driving gear 20 to rotate clockwise. The driving gear 20 drives the driven gear 18 on the right side to rotate counterclockwise. The driven gear 18 on the right side drives the driven gear 18 on the left side to rotate counterclockwise. The two driven gears 18 drive the two rotating shafts 10 to rotate in opposite directions.

[0049] The right rotating shaft 10 drives the right winding wheel 11 to rotate counterclockwise, and the right winding wheel 11 reels up the right end of the draw rope 15. At the same time, the left rotating shaft 10 drives the left winding wheel 11 to rotate clockwise, and the left winding wheel 11 reels up the left end of the draw rope 15. The draw rope 15 is gradually tightened as a whole, and the draw rope 15 pulls the multiple arc-shaped blocks 13 to swing toward the center of the rubber sleeve 1. The end of the rubber sleeve 1 is provided with multiple give way grooves. The arc-shaped blocks 13 drive the end of the rubber sleeve 1 to swing toward the center of the rubber sleeve 1, and the end of the rubber sleeve 1 is retracted. Tighten, the end of the rubber sleeve 1 gradually contacts the wire harness. When the rubber sleeve 1 is tightly fitted with the wire harness, the wire harness is fixed on the rubber sleeve 1. Then the hand wheel 21 is moved toward the ring 9. The hand wheel 21 drives the multiple limit blocks 25 to be reinserted into the limit groove 24. At this time, the hand wheel 21 cannot rotate freely. The staff can take the upper step to rotate another hand wheel 21, so as to tighten the other end of the rubber sleeve 1 and complete the fixation of the automobile wire harness. The wire harness is bound to the rubber sleeve 1 by fixing at two positions, and the fixation is more secure.

[0050] When the wire harness is subjected to impact force, the wire harness pulls the rubber sleeve 1 to move, and the rubber sleeve 1 drives the two inner cylinders 2 and the connecting rod 3 in the groove 4 to move, and the inner cylinder 2 squeezes the return spring 16 between the stopper 6, and the return spring 16 can offset part of the impact force, thereby reducing the pulling of the wire harness and preventing the impact force from pulling the rubber sleeve 1 out of the sheet metal. Another return spring 16 can offset part of the impact force in another direction;

[0051] When the staff needs to repair the wiring harness, they can first pull the hand wheel 21, and then rotate the hand wheel 21 counterclockwise while keeping the hand wheel 21 pulled. The hand wheel 21 drives the driving gear 20 to rotate counterclockwise through the T-shaped shaft 19, and the driving gear 20 drives the two driven gears 18 to rotate in opposite directions. The two driven gears 18 drive the two rotating shafts 10 to rotate in opposite directions. The two rotating shafts 10 drive the two winding wheels 11 opposite to each other on the left and right to rotate in opposite directions. The pull rope 15 on the winding wheel 11 gradually unfolds, and the end of the rubber sleeve 1 gradually loosens. At this time, the staff can easily take the wiring harness out of the rubber sleeve 1, and the staff can also rotate the second retaining ring 8 counterclockwise to remove the second retaining ring 8 from the outer cylinder 5, and then take the outer cylinder 5 out of the sheet metal hole, so as to repair the wiring harness.
