Description

Technical Field

[0001] The invention belongs to the technical field of connection between tubular bodies, and in particular relates to a locking mechanism for connecting a wiring harness of a new energy vehicle. Background Art

[0002] New energy vehicles, especially those based on pure electric platforms, require electricity to drive their main power source and the operation of the electronic control mechanisms in the vehicle. Therefore, the wiring harness connection mechanism used is different from that of conventional fuel vehicles and needs to meet the connection requirements of high-voltage current.

[0003] With the rapid development of society, the types and numbers of cars are growing rapidly. In recent years, people have begun to advocate the concept of energy conservation and emission reduction. A large number of new energy vehicles are used in our lives. Most of the new energy vehicles are now electric or mainly powered by electricity. Such a structured car requires a large number of wiring harness connections to transmit kinetic energy or signals through the wiring harness.

[0004] Existing connection harnesses are mostly connected by snap-fitting, and new energy vehicles often need to travel long distances and on bumpy roads. At this time, the vibrations encountered by new energy vehicles can easily cause the harnesses to separate. In new energy vehicles, these connection harnesses are very important. Once separated, it is likely that the acceleration, braking, power and other directions of the vehicle will be abnormal. When the vehicle is driving at high speed, once there is a little abnormality, it will cause a greater safety hazard; At the same time, after the existing wiring harness is connected, it is mostly exposed to the outside. When there is heavy rain, some water droplets from the outside are likely to enter the wiring harness connection along the line, or some dust will gather at the wiring harness connection, which will greatly affect the connection and normal use of the wiring harness. If this continues for a long time, it will also cause certain safety hazards. For this reason, we propose a locking mechanism for the wiring harness of new energy vehicles.

[0005] To solve the existing problem, we propose a locking mechanism for connecting the wiring harness of a new energy vehicle. Summary of the invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 10 The present invention provides a technical solution: a locking mechanism for connecting a wiring harness of a new energy vehicle, comprising a first wiring harness box 11 and a second wiring harness box 21, wherein the end of the first wiring harness box 11 is connected to a first integrated wire layer 13 through a protective thickening layer 12, and the end of the second wiring harness box 21 is provided with a second integrated wire 22, and further comprising: The locking mechanism is used to lock the first harness box 11 and the second harness box 21, and includes a locking seat 32 and a locking buckle column 34, which are used in conjunction with each other; The tubular body connection mechanism includes a sealing sleeve 51, and the sealing sleeve 51 wraps the connected first wire harness box 11 and the second wire harness box 21.

[0024] The present invention can lock the connecting wire harness, reduce and improve the stability of the wire harness when it is connected. After the wire harness is connected, the wire harness can be further fixed by the locking structure. The locking structure itself needs to be manually opened and closed by the staff. It is difficult to open the locking structure at a specific angle and force only by the vibration of the car. The safety of the wire harness is improved, the situation of easy separation of the wire harness is reduced, and the safety of new energy vehicles is improved.

[0025] In this embodiment, preferably, Figure 1 , Figure 2 The locking seats 32 are symmetrically distributed on both sides of the second wiring harness box 21, and each locking seat 32 is rotatably connected to the second wiring harness box 21 through two locking shafts 33. A locking ring buckle 35 is formed at the end of the locking seat 32, and a buffer convex ring 37 is provided at the end of the locking ring buckle 35. At least one deformation groove 36 is opened between the locking ring buckle 35 and the buffer convex ring 37.

[0026] The locking seat 32 can be rotated by the locking shaft 33 so that the locking seat 32 is rotated to Figure 2 At this time, the groove formed by the locking seat 32 and the locking ring buckle 35 just engages the locking buckle column 34, thereby achieving the effect of locking the first wiring harness box 11 and the second wiring harness box 21.

[0027] In this embodiment, preferably, Figure 1 , Figure 2 The locking buckle column 34 is symmetrically distributed on both sides of the outer wall of the first wiring harness box 11, and the locking buckle column 34 is used in conjunction with the locking ring buckle 35. When the locking ring buckle 35 is connected to the locking buckle column 34, the locking buckle column 34 is engaged in the groove formed by the locking ring buckle 35 and the locking seat 32; Locking handles 31 are symmetrically provided on both sides of the locking seat 32 .

[0028] The deformation groove 36 can deform the buffer convex ring 37. When the locking ring buckle 35 and the buffer convex ring 37 come into contact with the locking buckle column 34, the deformation groove 36 will shrink under the pressure of the force, so that the buffer convex ring 37 just fits with the locking buckle column 34. When the force is lost, the deformation groove 36 returns to its original size. At this time, the locking buckle column 34 and the buffer convex ring 37 cannot separate by themselves.

[0029] In this embodiment, preferably, Figure 3 , Figure 4 , Figure 5 The locking mechanism further includes a first limiting convex plate 41 and a second limiting convex plate 44. The first limiting convex plate 41 is symmetrically distributed on both sides of the first wiring harness box 11. A limiting top buckle seat 42 is provided on the top of the first limiting convex plate 41. A limiting inclined pad 43 is provided on the surface of the limiting top buckle seat 42 close to the first wiring harness box 11. The second limiting protrusions 44 are symmetrically distributed on both sides of the second wiring harness box 21 . A rotating cylinder 45 is provided on the second limiting protrusions 44 . A buckle hoop 46 is rotatably connected to the rotating cylinder 45 . A buckle area 47 is formed in the middle of the buckle hoop 46 , and the buckle area 47 is used in conjunction with the limiting tilt pad 43 .

[0030] The locking mechanism and Figure 1 , Figure 2 The locking structures adopt different structural modes, but all of them play the role of locking the first wiring harness box 11 and the second wiring harness box 21 when they are connected, and all of them play the role of further enhancing the stability when the first wiring harness box 11 and the second wiring harness box 21 are connected.

[0031] In this embodiment, preferably, a locking rotating rod 48 is provided on both sides of the bottom end of the clamping hoop 46, and the locking rotating rod 48 is placed inside the rotating cylinder 45, and the two rotate relative to each other; when the clamping hoop 46 is connected to the limiting top buckle seat 42, the surface of the clamping hoop 46 and the limiting inclined pad 43 fit each other.

[0032] When in use, it is only necessary to rotate the buckle hoop 46 through the locking rotating rod 48, so that the buckle hoop 46 and the buckle area 47 are moved to the position of the limiting top buckle seat 42, so that the limiting inclined pad 43 is tightly fitted with the buckle area 47, that is, the first wiring harness box 11 and the second wiring harness box 21 are connected to achieve a further limiting effect.

[0033] In this embodiment, preferably, the sealing sleeve 51 is a symmetrical structure, one side of the sealing sleeve 51 is rotatably connected to the second rotating ring 64, one side of the second rotating ring 64 is fixedly connected to the first rotating outer ring 53, a plurality of arcuate threaded rails 65 are provided on the surface of the second rotating ring 64, a plurality of limiting buckle caps 66 are provided at the end of the sealing sleeve 51, and the limiting buckle caps 66 pass through the arcuate threaded rails 65 to be connected to the second rotating ring 64, and the second rotating ring 64 is rotatably connected to the end face of the sealing sleeve 51 through the limiting buckle caps 66 and the arcuate threaded rails 65.

[0034] By setting the sealing sleeve 51, the safety of the wiring harness is further improved, and it has a splash-proof effect. The sealing sleeve 51 completely wraps the wiring harness connection and can also fix the two ends of the wiring harness, greatly reducing the gap after the first wiring harness box 11 and the second wiring harness box 21 are connected, reducing the entry of dust and water into the wiring harness connection, having a dust-proof and splash-proof effect, reducing the abnormality of the wiring harness connection, and further reducing the self-separation of the wiring harness, achieving a double fixing effect, and being more convenient to use.

[0035] In this embodiment, preferably, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 The middle part of the second rotating ring 64 is movably connected with multiple arc-shaped limit blocks 61, and the middle parts of the multiple arc-shaped limit blocks 61 form a cylindrical structure. Each arc-shaped limit block 61 is connected to the second rotating ring 64 through an arc-shaped linkage column 62, and the end of the arc-shaped linkage column 62 is rotatably connected to the second rotating ring 64 through a limited rotating axis 63.

[0036] A plurality of arc-shaped limit blocks 61 can be used to fix and limit the first integrated line layer 13 and the second integrated line 22 of different sizes. The arc-shaped limit blocks 61 can be opened according to usage requirements. The arc-shaped limit blocks 61 are composed of a plurality of arc-shaped blocks, and the distance between each arc-shaped limit block 61 can also be adjusted according to requirements. This allows the arc-shaped limit blocks 61 to fix the first integrated line layer 13 and the second integrated line 22 of different diameters more firmly. The arc-shaped limit blocks 61 are also wrapped in the flexible sealing rubber sleeve 52, so that when the arc-shaped limit blocks 61 contact the first integrated line layer 13, the first integrated line layer 13 will not be damaged.

[0037] In this embodiment, preferably, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 The end surface of the sealing sleeve 51 is provided with a linkage groove 57, and a plurality of first adjustment column rings 67 are provided on the curved side wall of the linkage groove 57, and the plurality of first adjustment column rings 67 are located on the outer side of the arc-shaped linkage column 62. When the plurality of arc-shaped limit blocks 61 and the arc-shaped linkage column 62 are in the closing process, the outer side of the arc-shaped linkage column 62 will contact with the plurality of first adjustment column rings 67, so that the plurality of arc-shaped limit blocks 61 are in the closed state; The end face of the sealing sleeve 51 is provided with a plurality of second adjustment column rings 68, and the plurality of second adjustment column rings 68 are located on the inner side of the arc-shaped linkage column 62. When the plurality of arc-shaped limit blocks 61 and the arc-shaped linkage column 62 are in the opening process, the second adjustment column rings 68 will press against the inner side of the arc-shaped linkage column 62, thereby making the plurality of arc-shaped limit blocks 61 in an open state.

[0038] When multiple arc-shaped limit blocks 61 need to be opened, the first rotating outer ring 53 can be rotated. The first rotating outer ring 53 is connected to the second rotating ring 64, so the second rotating ring 64 is driven to rotate together, and the limiting buckle cap 66 is in the arc-shaped threaded slide rail 65, so when the second rotating ring 64 rotates, it will not separate from the sealing sleeve 51. When the second rotating ring 64 rotates, it will drive the arc-shaped linkage column 62 and the arc-shaped limit block 61 to rotate together. When the arc-shaped linkage column 62 contacts the second adjustment column ring 68, the arc-shaped linkage column 62 is subjected to resistance from the second adjustment column ring 68 during its rotation, that is, the arc-shaped linkage column 62 and the arc-shaped limit block 61 rotate with the limiting rotation axis 63 as the center, thereby putting multiple arc-shaped limit blocks 61 in an open state; When the multiple arc-shaped limit blocks 61 are closed, similarly to the above, the first rotating outer ring 53 is rotated, and the first rotating outer ring 53 drives the second rotating ring 64, the arc-shaped linkage column 62, and the arc-shaped limit blocks 61 to rotate. When the arc-shaped linkage column 62 contacts the second adjustment column ring 68, the arc-shaped linkage column 62 is subjected to resistance from the first adjustment column ring 67 during its rotation, that is, the arc-shaped linkage column 62 and the arc-shaped limit blocks 61 rotate with the limited rotation axis 63 as the center, thereby putting the multiple arc-shaped limit blocks 61 in a closed state. That is, it has the effect of opening or clamping and fixing the first integrated line layer 13 and the second integrated line 22.

[0039] In this embodiment, preferably, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10A flexible sealing rubber sleeve 52 is provided on the outer wall of the first rotating outer ring 53, and the other side of the flexible sealing rubber sleeve 52 is fixed on the inner wall of the second rotating ring 64. The flexible sealing rubber sleeve 52 is made of a flexible sealing material and has an overall annular structure, and wraps the arc limit block 61 inside. When the arc limit block 61 is in an open state, the flexible sealing rubber sleeve 52 is in an open state together with the arc limit block 61; when the arc limit block 61 is in a closed state, the flexible sealing rubber sleeve 52 is in a closed state together with the arc limit block 61.

[0040] The connection between the flexible sealing rubber sleeve 52 and the first rotating outer ring 53 and the second rotating ring 64 is a sealed connection. At the same time, the flexible sealing rubber sleeve 52 wraps the plurality of arc-shaped limit blocks 61 so that the arc-shaped limit blocks 61 will not directly contact the outside world, so that the arc-shaped limit blocks 61 can be protected by the flexible sealing rubber sleeve 52 when fixing the first integrated line layer 13 and the second integrated line 22. At the same time, it can also play a dustproof and water splashing effect, so that the dust and water splashing from the outside are blocked by the sealing sleeve 51 and the flexible sealing rubber sleeve 52, and it is difficult to enter the connection between the first wiring harness box 11 and the second wiring harness box 21.

[0041] It is very simple to use, and the opening or closing of the plurality of arc-shaped limit blocks 61 can be achieved by simply rotating the first rotating outer ring 53 .

[0042] In this embodiment, preferably, Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 An adjusting circular groove 55 for use with the arc-shaped limit block 61 is opened in the middle of the first rotating outer ring 53 , and limiting screw holes 56 are opened on both sides of the first rotating outer ring 53 , and the limiting screw holes 56 are located directly above the arc-shaped threaded slide rail 65 .

[0043] The limiting screw hole 56 and the arc-shaped threaded slide rail 65 can be used in conjunction with each other, thereby achieving a limiting effect on the first rotating outer ring 53 and the second rotating ring 64. When the second rotating ring 64 moves and drives the arc-shaped limiting block 61 to change its state, the bolt can be inserted through the limiting screw hole 56 and pass through the arc-shaped threaded slide rail 65 to press against the end surface of the sealing sleeve 51, thereby achieving a fixing effect on the second rotating ring 64 and the first rotating outer ring 53 and reducing the situation where the two separate on their own.

[0044] Working principle and use process: When in use, the sealing sleeve 51 is installed at the connection between the first wiring harness box 11 and the second wiring harness box 21, so that the sealing sleeve 51 wraps the first wiring harness box 11 and the second wiring harness box 21. First, the sealing sleeve 51 is installed on the first wiring harness box 11 or the second wiring harness box 21, and then the first wiring harness box 11 is connected to the second wiring harness box 21; Then, the buckle hoop 46 is rotated by the clamping rotating rod 48, so that the buckle hoop 46 and the buckle area 47 are moved to the position of the limit top buckle seat 42, so that the limit inclined pad 43 is closely fitted with the buckle area 47, that is, the first wiring harness box 11 and the second wiring harness box 21 are connected to achieve a further limit effect; Then, the other side of the sealing sleeve 51 is installed on the second wiring harness box 21; By rotating the adjusting circular groove 55, the arc-shaped limit block 61 is driven to be in a closed state, so that the two ends of the sealing sleeve 51 are fixed to the first integrated wire layer 13 and the second integrated wire 22; When multiple arc-shaped limit blocks 61 need to be opened, the first rotating outer ring 53 can be rotated, and the first rotating outer ring 53 is connected to the second rotating ring 64, so the second rotating ring 64 is driven to rotate together, and the limiting buckle cap 66 is in the arc-shaped threaded slide rail 65, so when the second rotating ring 64 rotates, it will not separate from the sealing sleeve 51, and when the second rotating ring 64 rotates, it will drive the arc-shaped linkage column 62 and the arc-shaped limit block 61 to rotate together, and when the arc-shaped linkage column 62 contacts the second adjusting column ring 68, the arc-shaped linkage column 62 is subjected to resistance from the second adjusting column ring 68 during its rotation, that is, the arc-shaped linkage column 62 and the arc-shaped limit block 61 are centered around the limited rotation axis 63. When the arc stop blocks 61 are closed, the first rotating outer ring 53 is rotated, and the first rotating outer ring 53 drives the second rotating ring 64, the arc linkage column 62, and the arc stop blocks 61 to rotate. When the arc linkage column 62 contacts the second adjusting column ring 68, the arc linkage column 62 is subjected to resistance from the first adjusting column ring 67 during its rotation, so that the arc linkage column 62 and the arc stop blocks 61 rotate with the limited rotation axis 63 as the center, thereby putting the multiple arc stop blocks 61 in a closed state; that is, the first integrated line layer 13 and the second integrated line 22 are opened or clamped and fixed. At the same time, the connection between the flexible sealing rubber sleeve 52 and the first rotating outer ring 53 and the second rotating ring 64 are all sealed connections. At the same time, the flexible sealing rubber sleeve 52 wraps multiple arc limit blocks 61 inside, so that the arc limit blocks 61 will not directly contact the outside world, so that when the arc limit blocks 61 are fixing the first integrated line layer 13 and the second integrated line 22, they can be protected by the flexible sealing rubber sleeve 52, and can also play a dust-proof and water-splashing effect, so that external dust and water splashes are blocked by the sealing sleeve 51 and the flexible sealing rubber sleeve 52, and it is difficult to enter the connection between the first wiring harness box 11 and the second wiring harness box 21.

[0045] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
