Detailed Description

Referring to fig. 1 to 5, a specific structure of a preferred embodiment of the present utility model is shown, the back door is composed of a housing 100 and a sealing plate covering one side of the housing 100, one side of the housing 100 contains an inner recess 200 integrally formed on the housing 100, a door handle 300 is movably connected in the inner recess 200 for opening the back door, the door handle 300 is a planar slat, an opening corresponding to the size of a first plate 401 is formed in the middle of the door handle 300, a through hole 402 is formed in the middle of the first plate 401, a limiting rod 403 is inserted in the through hole 402, the limiting rod 403 is fixed to the opening on the door handle 300, so that the first plate 401 can rotate around the limiting rod 403, and an external pedestrian can easily see the first plate 401 through the movement of the first plate 401, and avoid approaching the back door;

However, the first plate 401 cannot be opened later, so that the transverse direction is changed into the longitudinal direction, and then the back door is closed, so that the longitudinal direction is changed into the transverse direction, for this purpose, the first pull rope 507 is fixed on the warning member 400 formed by the first plate 401, the first pull rope 507 extends to the back of the shell 100 and is connected with the box 501 at the back of the shell 100, the box 501 contains a cavity 502, the middle part of the cavity 502 is connected with a rotating rod 503 through a bearing, the rotating rod 503 is sleeved with a second torsion spring 504, two ends of the second torsion spring 504 are respectively fixed with the rotating rod 503 and the cavity 502, and after the first pull rope 507 is connected with the rotating rod 503, the rotating rod 503 can enable the first plate 401 to be in the longitudinal or transverse state, but still not be changed later due to the change of the state of the back door;

Therefore, a second pull rope 509 is sleeved and fixed on the rotating rod 503 in the opposite direction to the first pull rope 507, the second pull rope 509 penetrates through the shell 100 and is connected with the automobile interior, namely, when the back door is opened through the joint of the hinge and the automobile shell, the second pull rope 509 then pulls the rotating rod 503 to rotate when the back door is opened, the rotating direction of the rotating rod 503 is opposite to the winding direction of the first pull rope 507, namely, the first pull rope 507 is loosened, the first plate 401 is changed from transverse direction to longitudinal direction due to the loosening of the first pull rope 507, namely, the first plate 401 is changed to protrude from the parallel direction of the door handle 300, so that the opening of the back door is prompted for a user, when the back door is closed, the second torsion spring 504 drives the rotating rod 503 to reset, and the rotating rod 503 winds the first pull rope 507 again, so that the first plate 401 is changed from protruding to parallel to the door handle 300.

However, when the rotating rod 503 rotates, if the first pull rope 507 and the second pull rope 509 are not separated, the two ropes are easy to wind mutually, therefore, the coil collecting disc 505 is fixed at one end of the rotating rod 503, the placing groove 506 is formed in the middle of the coil collecting disc 505, the first pull rope 507 is wound and fixed in the placing groove 506, so that the two ropes are prevented from winding mutually, the partition 508 is fixed between the coil collecting disc 505 and the second torsion spring 504, and the rotating rod 503 penetrates through the partition 508, so that the situation that the two ropes wind mutually is further avoided.

At this time, the first plate 401 can be opened to protrude outside, then the back door is closed and parallel to the door handle 300, but for the aesthetic problem when the back door is used on the automobile, the size and the length of the first plate 401 are smaller than those of the door handle 300, so that the prompt for pedestrians is limited, and when the pedestrians are too close to the back door and cannot stop or pause to form immediately, excessive extrusion is easily caused to the first plate 401, so that the painted surface of the back door is damaged by friction between the first plate 401 and the inner wall of the inner notch 200;

Therefore, the two ends of the first plate 401 are provided with the sockets 405, the springs 406 are fixed in the sockets 405, one ends of the springs 406 are fixed on the second plate 407, and the second plate 407 protrudes from the inside of the sockets 405 to the outside, at this time, when the first plate 401 is excessively rotated due to external extrusion, the second plate 407 can move into the sockets 405 through the extrusion of the springs 406, so as to reduce the damage to the paint surface in the inner recess 200, in order to further reduce the damage to the paint surface in the inner recess 200, the buffer pads 408 are fixed at the opposite ends of the second plate 407, and the buffer pads 408 can be made of rubber.

In summary, the design of the present utility model is focused on that by fixing the wire collecting disc 505 at one end of the rotating rod 503, fixing the first pull rope 507 in the placement groove 506 of the wire collecting disc 505, and fixing the partition 508 between the wire collecting disc 505 and the second torsion spring 504, the two ropes can be effectively prevented from winding each other, and by opening the socket 405 at two ends of the first plate 401, fixing the spring 406, and fixing the second plate 407 on the spring 406, the second plate 407 can move into the socket 405 when the first plate 401 is excessively extruded, thereby reducing the damage to the paint surface in the inner recess 200, and simultaneously, fixing the buffer 408 at the opposite end of the second plate 407, further reducing the damage to the paint surface in the inner recess 200 when the second plate 407 is excessively extruded.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model are still within the scope of the technical solutions of the present utility model.
