The position of the vehicle door plug-in component 32 is taken as an example below: the vehicle door plug-in base 3211 is fixed to the vehicle door 1 through the vehicle door plug-in basic sleeve 321, and the handheld wiring harness plug-in sleeve 322 is moved toward the side of the vehicle door plug-in basic sleeve 321. During the movement of the movable clamping block 5, the inclined surface of the inclined wedge block 1 51 conflicts with the lower inclined surface of the inclined wedge block 2 53. Affected by the structure of the inclined wedge block 1 51, the movable clamping block 5 and the inclined wedge block 1 51 are gradually pulled down.

When the locking cam 531 is in the locked state, the locking cam 532 is in the locked state, and the locking cam 532 is in the locked state.

[0025] Embodiment 4, refer to the attached Figure 1-16, on the basis of Embodiment 3, in order to achieve external strengthening protection after the initial limit of the door plug-in base sleeve 321 and the wire harness plug-in socket 322, this embodiment further proposes: The first edge guard 6 is fixedly installed on both side surfaces of the door plug-in base sleeve 321. A horizontal groove is formed on the inner wall of the first edge guard 6, and limit grooves 60 are respectively formed on both inner side walls of the horizontal groove. The limit grooves 60 form an "L"-shaped empty groove structure. A limit slider 6111 is movably installed on the inner surface of the limit groove 60, and an abutting push plate 611 is fixedly connected to the inner surface of the limit slider 6111; An elastic abutting block 61 is fixedly installed on the side of the abutting push plate 611 away from the second edge guard 7, and a movable locking plate 612 is fixedly connected to the other side of the abutting push plate 611. There are two groups of movable locking plates 612, and a pull rod 6121 is fixedly welded to the upper ends of the two groups of movable locking plates 612; The second edge guard 7 has a "C"-shaped plate structure and is fixedly installed on both outer surfaces of the wire harness plug-in socket 322. A docking convex plate 71 is fixedly installed on the inner surface of the second edge guard 7, and the outer surface of the docking convex plate 71 is movably connected to the inner bottom surface of the horizontal groove; A locking hole 711 is formed on the outer surface of the docking convex plate 71, and the inner surface of the locking hole 711 is adaptively connected to the movable locking plate 612; The movable locking plate 612 is of an elastic structure, and a locking convex block is fixedly added to the lower surface of the movable locking plate 612. The outer surface of the locking convex block is adaptively embedded in the inner wall of the locking hole 711; In the present embodiment, by installing the side guard plate 1 6 and the side guard plate 2 7 on both sides of the vehicle door plug-in basic sleeve 321 and the wiring harness plug-in sleeve seat 322 respectively, it is possible to achieve matching installation of the sides of the two, and play a role in protecting the sides of the vehicle door plug-in basic sleeve 321 and the wiring harness plug-in sleeve seat 322; specifically, when the wiring harness plug-in sleeve seat 322 approaches the vehicle door plug-in basic sleeve 321, the docking protrusion 71 is inserted into the horizontal groove on the inner side of the side guard plate 1 6, and after the wiring harness plug-in sleeve seat 322 and the vehicle door plug-in basic sleeve 321 are completely pressed against each other, the side guard plate 1 6 and the side guard plate 2 7 are tightly attached, the operator holds the pull rod 6121 and pulls the abutting push plate 611 horizontally to move it close to the side of the side guard plate 2 7, and then pulls the pull rod 6121 outward to bend the movable locking plate 612, and then releases the pull rod 612. 1, so that the movable lock plate 612 returns to its initial position under the reverse elastic force. At this time, the locking protrusion on the inner side of the movable lock plate 612 enters the lock hole 711 for staggered locking, thereby achieving double locking of the door plug-in basic cover 321 and the wiring harness plug-in cover seat 322, and will not cause the plug-in wiring harness 4 to fall off at will. The reason why the elastic abutment block 61 is connected to the back side of the abutment push plate 611 is to rely on the elastic abutment of the elastic abutment block 61 to prevent the abutment push plate 611 from moving at will; it should be noted that the limit groove 60 is designed as an "L"-shaped groove structure. When the door plug-in basic cover 321 is in an unplugged state, the abutment push plate 611 and the limit slider 6111 are moved to the short groove position of the limit groove 60. When in use, it is only necessary to move the limit slider 6111 to the long groove position of the limit groove 60 to achieve unlocking.

[0026] Embodiment 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, in order to realize the arrangement of the wiring harness 4, the present embodiment further proposes that: a wiring harness assembly 324 is fixedly installed on the inner surface of the side of the wiring harness plug-in socket 322 away from the vehicle door plug-in basic socket 321, and the wiring harness assembly 324 includes a soft elastic wiring harness plate 3241, and the soft elastic wiring harness plate 3241 is provided with two groups, and the two groups of soft elastic wiring harness plates 3241 are symmetrically distributed about the longitudinal center axis of the wiring harness plug-in socket 322; the outer surfaces of the soft elastic wiring harness plates 3241 are respectively provided with arc grooves , and both ends of the soft elastic cable tie plate 3241 are connected to electromagnets respectively; the inner surface of the soft elastic cable tie plate 3241 is fixedly installed with a separation side piece 3242 and an elastic cable protection silicon sleeve 3243, the separation side piece 3242 is symmetrically distributed about the elastic cable protection silicon sleeve 3243, and a deformation groove is opened on the inner wall of the elastic cable protection silicon sleeve 3243. The elastic cable protection silicon sleeve 3243 is deformed by the thrust of the separation side pieces 3242 on both sides and forms a "C"-shaped groove structure, and the opening position of the "C"-shaped groove is movably connected with an anti-dropping piece 3244; In this embodiment, the patch cord 4 and the connecting cord are passed through the threading hole 3230, and the cord assembly 324 provided in the inner protective cover 323 can flexibly process the connection between the cord and the patch cord 4 to avoid the breakage of the cord caused by repeated opening and closing of the door 1, and the electromagnets at both ends of the flexible elastic cord plate 3241 are controlled to open. Under the action of mutual attraction, the ends of the two sets of flexible elastic cord plates 3241 are connected, and the flexible elastic cord plates 3241 that were originally in a parallel state are transformed into an O-shaped structure, so that the inner cord is wrapped, and the outer side of the flexible elastic cord plate 3241 is evenly opened. The arc groove can provide space for the deformation and stretching of the soft elastic cable bundle plate 3241. When the two sets of soft elastic cable bundle plates 3241 are connected end to end, the separating side pieces 3242 on both sides resist the elastic cable protection silicon sleeve 3243, and the wrapped cable bundle is tightly abutted through the anti-slip sheet 3244. At the same time, the cable bundle is prevented from repeatedly rubbing against the inner wall of the inner protective cover 323 to avoid damage to the outer skin of the cable bundle. The C-shaped structure formed by the elastic cable protection silicon sleeve 3243 can protect the bent and twisted cable bundle, extend the service life of the cable bundle, and avoid failure of the connecting lines between modules.

[0027] The working principle and use process of the present invention are as follows: First, the integrated millimeter wave radar sensing module, the control unit processing module and the adjustable response module are installed on the inner side of the door sealing plate 11, and the four are electrically connected. The modules are connected through the interface connection line, and pass through the threading groove 21 to the door plug-in basic sleeve 321. Then, the handheld wire harness plug-in sleeve seat 322 is moved to one side of the door plug-in basic sleeve 321. During the movement of the active card block 5, the inclined surface of the inclined wedge block 1 51 conflicts with the lower inclined surface of the inclined wedge block 2 53, and the inclined wedge is affected by the inclined wedge. Due to the influence of the structure of the block 51, the movable card block 5 and the inclined wedge block 51 are gradually pulled down. At this time, the reverse pull spring 521 is subjected to the downward force of the upper flange of the movable card block 5, and elastic compression is generated. At this time, the middle partition 511 is adapted to penetrate the inner side of the dividing groove 530. When the wiring harness plug-in socket 322 completely reaches the assembly position, the side of the wiring harness plug-in socket 322 close to the door plug-in basic socket 321 is in close contact with the sealing ring 3212. In this way, the sealing of the two is increased through the sealing ring 3212, which has a better sealing and waterproof effect. It needs to be explained When the inclined wedge block 1 51 arrives at the position, the movable clamping block 5 and the inclined wedge block 1 51 are elastically charged by the reverse pulling spring 521, and the movable clamping block 5 and the inclined wedge block 1 51 will always be in close contact with the lower inclined surface of the inclined wedge block 2 53, thereby realizing the automatic locking between the door plug-in basic sleeve 321 and the wiring harness plug-in sleeve seat 322; in addition, the operator holds the pull rod 6121 and pulls the abutting push plate 611 horizontally to move it close to the side of the sleeve edge guard plate 2 7, and then pulls the pull rod 6121 outward to make the movable locking plate 612 bend, and the movable locking plate 612 is bent. After that, the pull rod 6121 is loosened, so that the movable lock plate 612 returns to its initial position under the reverse elastic force. At this time, the locking protrusion on the inner side of the movable lock plate 612 enters the lock hole 711 for staggered locking, thereby achieving double locking of the door plug-in basic cover 321 and the wiring harness plug-in cover seat 322, and will not cause the plug-in wiring harness 4 to fall off at will. The wiring harness protection cover 3 is connected to the position close to the door 1 and the vehicle body in turn to ensure the stability of the line connection, ensure accurate monitoring of the coordinates of obstacles beside the vehicle, and ensure that the door 1 can avoid obstacles and collisions in time, thereby improving the obstacle avoidance performance of the entire vehicle.
