The specific implementation process is as follows:
taking the left back door of the automobile as an example, the stud penetrates through the second mounting hole 7, the second mounting plate 5 is fixedly arranged on the automobile body, the stud penetrates through the first mounting hole 6, the left back door of the automobile is fixedly arranged on the first mounting hole 6, at the moment, the left back door is in a closed state, the locking gear 27 is attracted to the second magnet 30, the spring 26 is in a compressed state, and the locking gear 27 is meshed with the second gear 18; the outer rings of the first one-way bearing 13 and the fourth one-way bearing 20 can only rotate anticlockwise relative to the inner rings, the outer rings of the second one-way bearing 19 and the third one-way bearing 14 can only rotate clockwise relative to the inner rings, and when the adjusting column rotates anticlockwise, the adjusting rod 24 moves upwards.
When the door is opened, the locking gear 27 is meshed with the second gear 18, the locking gear 27 cannot rotate, the second gear 18 is fixedly connected with the second pin shaft 17, the second pin shaft 17 is fixedly connected with the third hinge 3, the third hinge 3 is fixedly connected with the vehicle body, so that the second gear 18 cannot rotate, and the second hinge 2 is fixed on the third hinge 3. The first hinge 1 is rotatable on the second hinge 2, so that the vehicle body can rotate along with the first hinge 1. When the first hinge 1 rotates, the first pin shaft 10 is driven to rotate clockwise, the first pin shaft 10 drives the first friction wheel 15 to rotate clockwise, the third friction wheel 16 idles clockwise, the first friction wheel 15 drives the upper friction wheel 33 to rotate clockwise under the action of friction force, the upper friction wheel 33 drives the adjusting column to rotate anticlockwise, the upper friction wheel 33 can also drive the second friction wheel 21 to idle clockwise, the adjusting rod 24 gradually moves upwards, and the locking gear 27 on the adjusting rod 24 is gradually separated from the second gear 18 until the locking gear 27 is contacted with the first gear 11; since the external thread 28 of the adjusting rod 24 has elasticity, the external thread 28 can be elastically deformed when passing through the lower adjusting post 34, so that the external thread 28 cannot be jammed. The locking gear 27 is close to the first magnet 29 and attracted to the first magnet 29, and in the process, if the teeth of the locking gear 27 and the first gear 11 are not completely staggered, the wedges on the two will push each other until the locking gear 27 and the first gear 11 can be meshed, and since the first gear 11 is provided with the first annular groove 38, the outer wall of the first pin shaft 10 is provided with the first arc key 37, the first gear 11 can rotate on the first pin shaft 10 by a small amplitude, so that the first gear 11 and the locking gear 27 are meshed.
After the locking gear 27 is attracted by the first magnet 29 and meshed with the first gear 11, the first gear 11 cannot rotate, and the first pin shaft 10 cannot rotate, so that the first hinge 1 cannot rotate relative to the second hinge 2, at this time, only the second hinge 2 can rotate relative to the third hinge 3, and the second hinge 2 can drive the first hinge 1 and the vehicle door to continue to rotate until the vehicle door rotates 270 degrees and abuts against the vehicle body. When the second hinge 2 rotates, because the friction force between the upper friction wheel 33 and the second friction wheel 21 is greater than the friction force between the upper friction wheel 33 and the first friction wheel 15, the upper friction wheel 33 rotates clockwise around the second friction wheel 21, and the upper friction wheel 33 slips on the first friction wheel 15, the upper friction wheel 33 drives the upper adjusting column 32 to rotate clockwise, the adjusting rod 24 starts to move downwards, the locking gear 27 gradually separates from the first gear 11 and approaches the second gear 18 until the locking gear 27 contacts the second gear 18, the locking gear 27 is attracted by the second magnet 30 and completely meshes with the second gear 18, at this time, the second hinge 2 and the third hinge 3 are locked and fixed again, and the vehicle door is opened to just 270 °.
When the vehicle door is closed, the second hinge 2 is locked with the third hinge 3, only the first hinge 1 can rotate, the vehicle door drives the first hinge 1 to rotate anticlockwise, the first hinge 1 drives the first pin shaft 10 and the third friction wheel 16 to rotate, the third friction wheel 16 drives the lower friction wheel 35 and the lower adjusting column 34 to rotate clockwise, the lower friction wheel 35 drives the fourth friction wheel 22 to idle anticlockwise, the adjusting rod 24 continues to move downwards, the locking gear 27 is gradually separated from the second gear 18 and close to the third gear 12, the third magnet 31 attracts the locking gear 27 and enables the locking gear 27 to be meshed with the third gear 12, and the first hinge 1 and the second hinge 2 are locked and fixed;
after the first hinge 1 and the second hinge 2 are locked and fixed, the second hinge 2 can rotate on the third hinge 3, at this time, the vehicle door is continuously closed, because the friction force between the lower friction wheel 35 and the fourth friction wheel 22 is greater than the friction force between the lower friction wheel 35 and the second friction wheel 21, the lower friction wheel 35 rotates counterclockwise relative to the second friction wheel 21, and the lower friction wheel 35 slips on the second friction wheel 21. The lower friction wheel 35 also drives the lower adjustment post 34 to rotate counterclockwise, the lower adjustment post 34 drives the adjustment rod 24 to move upward, the locking gear 27 gradually separates from the third gear 12 and approaches the second gear 18, and the second magnet 30 attracts the locking gear 27 and causes the locking gear 27 to engage with the second gear 18, so that the door is completely closed.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
