Description

TECHNICAL FIELD

[0002] The main power source and the operation of the in-vehicle electric control mechanism of a new energy automobile, especially a new energy automobile based on a pure electric platform, need to be driven by electricity, so the wire harness connection mechanism used is different from that of a conventional fuel vehicle and needs to meet the connection requirements of high-voltage current.

[0003] With the rapid development of society, the types and quantities of automobiles are increasing dramatically, and in recent years, people have begun to advocate the concept of energy saving and emission reduction. A large number of new energy automobiles are used in our lives, and most of the new energy automobiles at present are electric or mainly use electricity with fuel as an auxiliary. Such automobiles need to use a large number of wire harness connections to transmit kinetic energy or signals through wire harnesses.

[0004] The existing connection wire harness is mostly connected through clamping, but new energy automobiles often need to travel a long distance and also travel on some land that is relatively bumpy. At this time, the vibration encountered by the new energy automobile can easily cause the wire harness to separate. In a new energy automobile, these connection wire harnesses are very important, and once separation occurs, the automobile acceleration, braking, power, etc. may be abnormal. When an automobile is traveling at high speed, any abnormality can cause a large safety hazard.

[0005] At the same time, after the existing wire harness is connected, it is mostly exposed to the outside. When a rainstorm occurs, some water droplets in the outside world can enter the wire harness connection place along the line, or some dust can accumulate in the wire harness connection place, which can affect the connection and normal use of the wire harness. Long-term use can also cause certain safety hazards. Therefore, we propose a locking mechanism of a new energy automobile connection wire harness.

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0046] Please refer to Figures 1 to 10 The present application provides a technical solution: a locking mechanism of a new energy automobile connecting wire harness, comprising a first wire harness box 11 and a second wire harness box 21, the end of the first wire harness box 11 is connected with a first comprehensive wire layer 13 through a protective thickening layer 12, the end of the second wire harness box 21 is provided with a second comprehensive wire 22, and further comprising:

[0047] The locking mechanism is used for locking the first wire harness box 11 and the second wire harness box 21, and comprises a locking seat 32 and a locking buckle column 34, which are used in cooperation;

[0048] The tubular body connecting mechanism comprises a sealing sleeve 51, which wraps the connected first wire harness box 11 and second wire harness box 21.

[0049] The application can realize locking of the connected wire harness, reduce the stability of the wire harness connection, and further fix the wire harness through the locking structure after the wire harness is connected. The locking structure needs to be manually opened and closed by the staff, and it is difficult to open the locking structure at a special angle and force only by the vibration of the automobile, thereby improving the safety of the wire harness, reducing the easy separation of the wire harness, and improving the safety of the new energy automobile.

[0050] In the embodiment, preferably, as Figure 1 、 Figure 2 The locking seats 32 are symmetrically distributed on both sides of the second wire harness box 21, and each locking seat 32 is rotationally connected to the second wire harness box 21 through two locking shafts 33. The end of the locking seat 32 forms a locking ring buckle 35, the end of the locking ring buckle 35 is provided with a buffer boss 37, and at least one deformation slot 36 is arranged between the locking ring buckle 35 and the buffer boss 37.

[0051] The locking seat 32 can be rotated through 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 is just clamped with the locking buckle column 34, thereby achieving the effect of locking the first wire harness box 11 and the second wire harness box 21.

[0053] The two sides of the locking seat 32 are symmetrically provided with a locking handle 31.

[0054] The deformation slot 36 can deform the buffer boss 37. When the locking ring buckle 35, the buffer boss 37 and the locking buckle column 34 are in contact and are extruded by the action force, the deformation slot 36 will shrink, so that the buffer boss 37 is just clamped with the locking buckle column 34. When the action force is lost, the deformation slot 36 returns to the original size, and at this time the locking buckle column 34 and the buffer boss 37 cannot be separated.

[0055] In the embodiment, preferably, as Figure 3 、 Figure 4 、 Figure 5The locking mechanism further includes a first limiting convex plate 41 and a second limiting convex plate 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.

[0057] The locking mechanism and Figure 1 、 Figure 2 The locking structures adopt different structural methods, 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 of the first wiring harness box 11 and the second wiring harness box 21 when they are connected.

[0058] 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 with 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.

[0059] When in use, it is only necessary to rotate the buckle hoop 46 through the locking 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.

[0060] In this embodiment, preferably, the sealing sleeve 51 has 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 arc-shaped threaded slide 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 arc-shaped threaded slide rails 65 and are 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 arc-shaped threaded slide rails 65.

[0061] The sealing sleeve 51 is arranged, the safety of the wire harness is further improved, and the water splash effect is achieved. The sealing sleeve 51 completely wraps the wire harness connection, and can also fix the two ends of the wire harness. The gap after the first wire harness box 11 is connected with the second wire harness box 21 is greatly reduced, the dust and water source entering the wire harness connection are reduced, the dust and water splash effects are achieved, the abnormal situation of the wire harness connection is reduced, the self-separation of the wire harness is further reduced, the double fixing effect is achieved, and the wire harness is convenient to use.

[0062] In the embodiment, preferably, as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The middle part of the second rotating ring 64 is movably connected with a plurality of arc-shaped limiting blocks 61, the middle parts of the plurality of arc-shaped limiting blocks 61 form a cylindrical structure, each arc-shaped limiting block 61 is connected with the second rotating ring 64 through an arc-shaped linkage column 62, and the end part of the arc-shaped linkage column 62 is rotationally connected with the second rotating ring 64 through a limiting rotation shaft 63.

[0063] The plurality of arc-shaped limiting blocks 61 can be used to fix and limit the first comprehensive wire layer 13 and the second comprehensive wire 22 with different sizes. The arc-shaped limiting blocks 61 can be opened according to the use requirement, the arc-shaped limiting blocks 61 are composed of a plurality of arc-shaped blocks, and the distance between each arc-shaped limiting block 61 can also be adjusted according to the requirement. Therefore, the arc-shaped limiting blocks 61 can be used to fix the first comprehensive wire layer 13 and the second comprehensive wire 22 with different diameters, and the arc-shaped limiting blocks 61 are wrapped in the flexible sealing rubber sleeve 52, so that the arc-shaped limiting blocks 61 will not damage the first comprehensive wire layer 13 when the arc-shaped limiting blocks 61 contact the first comprehensive wire layer 13.

[0064] In the embodiment, preferably, as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The end surface of the sealing sleeve 51 is provided with a linkage groove 57, a plurality of first adjusting column rings 67 are arranged on the curved side wall of the linkage groove 57, and the plurality of first adjusting column rings 67 are located outside the arc-shaped linkage column 62. When the plurality of arc-shaped limiting blocks 61 and the arc-shaped linkage column 62 are in the closing process, the outside of the arc-shaped linkage column 62 will contact the plurality of first adjusting column rings 67, so that the plurality of arc-shaped limiting blocks 61 are in the closed state.

[0065] The end surface of the sealing sleeve 51 is provided with a plurality of second adjusting column rings 68 which are located on the inner side of the arc-shaped linkage column 62. When the plurality of arc-shaped limiting blocks 61 and the arc-shaped linkage column 62 are in the opening process, the second adjusting column rings 68 abut against the inner side of the arc-shaped linkage column 62, so that the plurality of arc-shaped limiting blocks 61 are in the open state.

[0066] When the plurality of arc-shaped limiting blocks 61 need to be opened, the first rotating outer ring 53 can be rotated. The first rotating outer ring 53 is connected with the second rotating ring 64, so as to drive the second rotating ring 64 to rotate together. The limiting buckle 66 is in the arc-shaped threaded slide rail 65, so that the second rotating ring 64 does not separate from the sealing sleeve 51 when it rotates. When the second rotating ring 64 rotates, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 rotate together. When the arc-shaped linkage column 62 contacts the second adjusting column ring 68, the arc-shaped linkage column 62 is resisted in the rotating process, so that the arc-shaped linkage column 62 and the arc-shaped limiting block 61 rotate with the limited rotating shaft 63 as the center, so that the plurality of arc-shaped limiting blocks 61 are in the open state.

[0067] When the plurality of arc-shaped limiting blocks 61 are closed, the first rotating outer ring 53 is rotated, which drives the second rotating ring 64, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 to rotate. When the arc-shaped linkage column 62 contacts the second adjusting column ring 68, the arc-shaped linkage column 62 is resisted in the rotating process, so that the arc-shaped linkage column 62 and the arc-shaped limiting block 61 rotate with the limited rotating shaft 63 as the center, so that the plurality of arc-shaped limiting blocks 61 are in the closed state.

[0068] That is, it has the effect of opening or clamping and fixing the first comprehensive wire layer 13 and the second comprehensive wire layer 22.

[0069] In this embodiment, preferably, as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The outer wall of the first rotating outer ring 53 is provided with a flexible sealing rubber sleeve 52, and the other side of the flexible sealing rubber sleeve 52 is fixed to the inner wall of the second rotating ring 64. The flexible sealing rubber sleeve 52 is made of flexible sealing material and has a ring-shaped arrangement structure, and the arc-shaped limiting block 61 is wrapped therein. When the arc-shaped limiting block 61 is in the open state, the flexible sealing rubber sleeve 52 is in the open state together with the arc-shaped limiting block 61. When the arc-shaped limiting block 61 is in the closed state, the flexible sealing rubber sleeve 52 is in the closed state together with the arc-shaped limiting block 61.

[0070] The connection between the flexible sealing sleeve 52 and the first rotating outer ring 53 and the second rotating ring 64 is a sealed connection, and meanwhile, the flexible sealing sleeve 52 wraps the plurality of arc-shaped limiting blocks 61, so that the arc-shaped limiting blocks 61 cannot be directly contacted with the outside, and the arc-shaped limiting blocks 61 can be protected by the flexible sealing sleeve 52 when fixing the first comprehensive wire layer 13 and the second comprehensive wire 22. Meanwhile, the flexible sealing sleeve 52 can also play the effects of dustproof and water splash prevention, so that the dust and water splash in the outside are blocked by the sealing sleeve 51 and the flexible sealing sleeve 52, and it is difficult to enter the connection between the first wire harness box 11 and the second wire harness box 21.

[0071] When used, it is very simple, only need to rotate the first rotating outer ring 53, so that the plurality of arc-shaped limiting blocks 61 can be opened or closed.

[0072] In the embodiment, preferably, as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The middle part of the first rotating outer ring 53 is provided with an adjusting circular groove 55 matched with the arc-shaped limiting block 61, and the two sides of the first rotating outer ring 53 are provided with limiting screw holes 56, and the limiting screw holes 56 are located directly above the arc-shaped screw thread sliding rails 65.

[0073] The limiting screw holes 56 and the arc-shaped screw thread sliding rails 65 can be matched and used, so that the limiting effect is played on the first rotating outer ring 53 and the second rotating ring 64. When the second rotating ring 64 moves to drive the arc-shaped limiting block 61 to change the state, the bolt can be inserted through the limiting screw hole 56 and passes through the arc-shaped screw thread sliding rail 65 to abut against the end face of the sealing sleeve 51, so that the fixing effect is played on the second rotating ring 64 and the first rotating outer ring 53, and the separation of the two is reduced.

[0074] Working principle and use process: when used, the sealing sleeve 51 is installed at the connection between the first wire harness box 11 and the second wire harness box 21, so that the sealing sleeve 51 wraps the first wire harness box 11 and the second wire harness box 21, the sealing sleeve 51 is first installed on the first wire harness box 11 or the second wire harness box 21, and then the first wire harness box 11 is connected with the second wire harness box 21.

[0075] Then the buckle hoop 46 is rotated through the carding rotating rod 48, so that the buckle hoop 46 and the buckle area 47 move to the position of the limiting top buckle seat 42, so that the limiting inclined pad 43 is tightly attached to the buckle area 47, that is, the first wire harness box 11 and the second wire harness box 21 are connected to play a further limiting effect;

[0076] Then the other side of the sealing sleeve 51 is installed on the second wire harness box 21.

[0077] And by rotating the adjusting circular groove 55, the arc-shaped limiting blocks 61 are in the closed state, thereby fixing the two ends of the sealing sleeve 51 to the first comprehensive wire layer 13 and the second comprehensive wire 22;

[0078] When multiple arc-shaped limiting blocks 61 need to be opened, the first rotating outer ring 53 can be rotated, the first rotating outer ring 53 is connected with the second rotating ring 64, so as to drive the second rotating ring 64 to rotate together, and the limiting buckle 66 is in the arc-shaped threaded slide rail 65, so that the second rotating ring 64 cannot be separated from the sealing sleeve 51 when the second rotating ring 64 rotates, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 are driven 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 resisted in the process of rotation by the second adjusting column ring 68, that is, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 rotate around the limited rotation shaft 63, so that multiple arc-shaped limiting blocks 61 are in the open state; when multiple arc-shaped limiting blocks 61 are closed, the first rotating outer ring 53 is rotated, the first rotating outer ring 53 drives the second rotating ring 64, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 to rotate, and when the arc-shaped linkage column 62 contacts the first adjusting column ring 67, the arc-shaped linkage column 62 is resisted in the process of rotation by the first adjusting column ring 67, that is, the arc-shaped linkage column 62 and the arc-shaped limiting block 61 rotate around the limited rotation shaft 63, so that multiple arc-shaped limiting blocks 61 are in the closed state; that is, the effect of opening or clamping and fixing the first comprehensive wire layer 13 and the second comprehensive wire 22 is achieved;

[0079] Meanwhile, 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, and the flexible sealing rubber sleeve 52 wraps multiple arc-shaped limiting blocks 61, so that the arc-shaped limiting blocks 61 cannot directly contact the outside, and the flexible sealing rubber sleeve 52 can protect the arc-shaped limiting blocks 61 when fixing the first comprehensive wire layer 13 and the second comprehensive wire 22, and can also prevent dust and water splashing, so that dust and water splashing from the outside are blocked by the sealing sleeve 51 and the flexible sealing rubber sleeve 52 and are difficult to enter the connection between the first wire harness box 11 and the second wire harness box 21.
