Referring to fig. 1 to 6, the pop-up buffer structure of the back door of the vehicle of the present invention includes a sleeve 1, a telescopic driving portion 2, an adjusting ring 3 and a buffer block 4. The sleeve 1 comprises a first sleeve 11 and a second sleeve 12, the second sleeve 12 being inserted inside the first sleeve 11 and being able to slide axially along the first sleeve 11. The flexible drive division 2 is located sleeve 1, and flexible drive division 2 in this embodiment is the spring, and the both ends of this spring respectively with the top of first sleeve 11 and the bottom of second sleeve 12 offset, and buffer block 4 inlays locates sleeve 1's bottom, and outside sleeve 1 was located to adjusting ring 3, and adjusting ring 3 can offset with buffer block 4 axial. In this embodiment, the sleeve 1 and the adjusting ring 3 are both plastic members, and the buffer block 4 is a rubber elastic member.
Further, the sleeve 1 further comprises an adaptive portion 1a, an installation portion 1d, a limiting portion 1c and a buffer block combining portion 1b, the adaptive portion 1a, the installation portion 1d, the limiting portion 1c and the buffer block combining portion 1b are all integrally formed with the sleeve 1, the adaptive portion 1a, the installation portion 1d and the limiting portion 1c are located on one of the first sleeve 11 and the second sleeve 12, and the buffer block combining portion 1b is located on the other of the first sleeve 11 and the second sleeve 12.
The limiting part 1c comprises a disc-shaped flange formed by extending outwards from the middle part of the cylinder wall of the sleeve 1 along the radial direction, the mounting part 1d and the self-adapting part 1a are respectively positioned at the upper side and the lower side of the limiting part 1c and are respectively used for being connected with the back door inner plate and the adjusting ring 3, and the buffer block combining part 1b is positioned below the self-adapting part 1a and is used for being connected with the buffer block 4.
In this embodiment, the mounting portion 1d is a threaded structure formed on the outer wall of the sleeve 1, the sleeve 1 is mounted below the inner panel of the back door in a threaded fit manner, and when the back door is closed, the pop-up buffer structure of the present invention is perpendicular to the doorsill of the back door.
Referring to fig. 7, the adaptive portion 1a includes two sets of external convex threads 6 disposed on the outer wall of the sleeve 1, the two sets of external convex threads 6 are symmetrically disposed along the radial direction of the sleeve 1, the arrangement included angle of the external convex threads 6 in the circumferential direction of the sleeve 1 (the included angle between the connection line of the two ends of the external convex threads 6 in the circumferential direction and the center of the corresponding portion of the sleeve 1) is greater than 80 ° and less than 90 °, and the other sleeve wall surfaces in the circumferential direction on the adaptive portion 1a are smooth surfaces. Referring to fig. 8, corresponding to the adaptive portion 1a, two sets of radially symmetrically disposed concave threads 5 are disposed on the inner wall of the adjusting ring 3, the arrangement angle of the concave threads 5 is 90 °, and other circumferential ring surfaces of the adjusting ring 3 are smooth surfaces. Referring to fig. 9, in the present embodiment, the inner diameter (the diameter of the smooth surface portion) of the adjusting ring 3 is larger than the inner diameter of the female screw 5 and smaller than the outer diameter of the female screw 5, and the outer diameter of the male screw 6 of the adaptive portion 1a is smaller than the outer diameter of the female screw 5 and larger than the inner diameter of the female screw 5, so that the male screw 6 can be smoothly inserted into the female screw 5 and has a certain radial movement space in the female screw 5. When the outer convex thread 6 of the self-adaptive part 1a is in contact with the smooth surface of the adjusting ring 3, the self-adaptive part 1a can generate interference with the smooth surface of the adjusting ring 3, the axial positioning of the adjusting ring 3 on the self-adaptive part 1a is assisted, and when the outer convex thread 6 is in threaded fit with the inner concave thread 5, the outer convex thread 6 can be clamped into the corresponding inner concave thread 5 because the thread included angle of the inner concave thread 5 is larger than that of the outer convex thread 6, and a certain circumferential motion space is formed in the inner concave thread 5.

Referring to fig. 3 to 6, when the pop-up buffer structure of the present invention is used for the first time, before the back door is closed, the position of the adjusting ring 3 is adjusted to a lower position on the adaptive portion 1a, and the smooth surface of the adjusting ring 3 is aligned with the external convex thread 6 on the adaptive portion 1 a. When the backdoor is closed, the buffer block 4 at the lower part of the bounce buffer structure is contacted with the backdoor threshold and is axially compressed, the telescopic driving part 2, the first sleeve 11 and the second sleeve 12 in the sleeve 1 move oppositely, the length of the sleeve 1 is shortened, and the bounce buffer structure is supported between the backdoor and the backdoor threshold by the supporting force of the telescopic driving part 2. Along with the further closing of the backdoor, the telescopic driving part 2 is further compressed, the lower part of the adjusting ring 3 is abutted against the upper part of the buffer block 4, the adjusting ring 3 moves relatively from bottom to top on the self-adaptive part 1a, the outer convex screw thread 6 on the self-adaptive part 1a is interfered with the smooth surface on the adjusting ring 3, and the bounce type buffer structure of the invention is supported between the backdoor and a backdoor threshold by the supporting force of the telescopic driving part 2 and the supporting force generated among the adjusting ring 3, the buffer block 4 and the self-adaptive part 1 a. After the backdoor is completely closed, the adjusting ring 3 is finally positioned at the highest position to which the adjusting ring can move due to the interference of the light surfaces, and the relative position self-adaptation of the adjusting ring 3 on the self-adaptation part 1a is completed. When the backdoor is opened, the backdoor is unlocked, the bounce type buffer structure enables the backdoor to bounce for a certain height by the restoring force of the telescopic driving part force 2, further a certain space is generated between the backdoor and a backdoor threshold, and then the backdoor is opened by hand operation. Particularly, after the vehicle door is opened again, due to the interference effect of the smooth surface, the adjusting ring 3 is still located at the highest position to which the adjusting ring can move, at the moment, the adjusting ring 3 only needs to be twisted by a certain angle according to the included angle of the threads, so that the concave threads 5 on the adjusting ring 3 are matched with the convex threads 6 on the self-adaptive part 1a, the adjusting ring 3 is fixed at the position more firmly, the relative position of the self-adaptive part 1a and the adjusting ring 3 is ensured not to change relatively after being adjusted, and more stable supporting force is provided for the later opening and closing of the backdoor. In the present embodiment, the torsion angle of the adjustment ring 3 is 90 °.
