[0031] Reference Figure 1-4 A zipper for a trunk lid of an automobile comprises a bottom plate 1, a boss 2 is fixedly arranged symmetrically on the top of the bottom plate 1, a fixing plate 3 is arranged on the top of the bottom plate 1, a groove 4 corresponding to the boss 2 is provided at the bottom of the bottom plate 1, a limiting hole 6 is provided on one side of the fixing plate 3, a latch 7 is movably connected to one side of the limiting hole 6, a support platform 9 is fixedly connected to the top of the bottom plate 1, a limiting slide groove 11 is provided on the side wall of the fixing frame 10, a driving motor 13 is fixedly connected to the top of the supporting platform 9, and the output end of the driving motor 13 is connected to the output end of the driving motor 13 through a coupling A screw rod 12 is fixedly connected, one end of the screw rod 12 passes through and is rotatably connected to a fixing frame 10, one end of the fixing frame 10 is fixedly connected to a fixing plate 3, a slider 14 is threadedly connected to the surface of the screw rod 12, one end of the slider 14 is fixedly connected to a connecting rod 15, one side of the connecting rod 15 is fixedly connected to a pushing rod 8, one end of the pushing rod 8 is fixedly connected to one end of a latch 7, a shock absorbing cylinder 18 is fixedly connected to the top of the fixing plate 3, a mounting opening 21 is opened at the top of the shock absorbing cylinder 18, and a gasket 22 is fixedly installed on the outer side of the mounting opening 21.
[0032] Specifically, the base plate 1 is riveted to the fixing plate 3, and the riveted surface is located inside the groove 4. This structure can achieve a firm rigid connection, ensuring the stability and reliability of the zipper during use, while making the riveted portion difficult to be observed by the outside world, thereby improving the aesthetics and overall decorative effect of the zipper, effectively reducing the probability of damage to the riveted surface, and improving the durability and service life of the zipper.
[0033] Specifically, a plurality of groups of threaded holes 5 are provided at both ends of the base plate 1. The arrangement of the threaded holes 5 makes it convenient for people to inspect or replace the automatic lock. The threaded holes 5 are symmetrically distributed about the central axis of the base plate 1. This structure can ensure uniform force during installation, reduce deformation or instability caused by improper assembly or eccentricity, and improve the reliability and stability of the product.
[0034] Specifically, two limit plates 16 are fixedly connected to one end of the fixing plate 3 facing the driving motor 13, and the two limit plates 16 are tightly fitted with the sides of the latch 7 respectively. This structure can effectively increase the stability and firmness of the latch 7, ensuring that the latch 7 can be accurately positioned in the correct position when opening or closing, avoiding the problem of incomplete locking or poor opening due to position deviation, and at the same time can reduce the friction between components, reduce energy loss, and improve the efficiency of the structure.
[0035] Specifically, a shock-absorbing spring 19 is fixedly installed on the inner bottom surface of the shock-absorbing cylinder 18. This structure can effectively reduce the impact and vibration generated when the trunk lid is closed, protect the trunk lid and related components, and improve the comfort of the car during driving. The number of shock-absorbing springs 19 is four groups, and the shock-absorbing springs 19 are arranged symmetrically about the center of the shock-absorbing cylinder 18. This structure can ensure that the trunk lid is subjected to balanced force during the closing process, avoid instability caused by eccentricity, and improve the stability of the system. The top of the shock-absorbing spring 19 is fixedly connected with a movable plate 20. This structure ensures that the shock-absorbing spring 19 can increase support during operation, better adapt to the deformation and position adjustment when the trunk lid is closed, and improve the shock absorption effect and reliability.
[0036] Specifically, reinforcing ribs 17 are fixedly connected between the limiting plate 16 and the fixing plate 3, and the number of the reinforcing ribs 17 is two groups. This structure can effectively reinforce the connection point between the limiting plate 16 and the fixing plate 3 to avoid loosening or breaking, thereby effectively improving the durability and stability of the entire zipper system during use.
[0037] Specifically, a docking lock block 23 that cooperates with each other is movably arranged between the two fixing plates 3, and a fixing hole 24 for the latch 7 to pass through is arranged on one side of the docking lock block 23. This structure allows the two fixing plates 3 to be firmly docked with the docking lock block 23 when closed, ensuring that the trunk lid is firmly closed, and can effectively prevent the trunk lid from being accidentally opened due to bumps during driving, thereby increasing the safety of the locking structure.
[0038] Specifically, the top of the docking lock block 23 is fixedly connected to a connecting plate 25, and the bottom of the connecting plate 25 is fixedly connected to a guide rod 26. The arrangement of the connecting plate 25 and the guide rod 26 can increase the connection stability between the docking lock block 23 and the fixing plate 3, so that the trunk lid can be firmly fixed on the vehicle body when closed. The diameter of the guide rod 26 is matched with the diameter of the mounting opening 21, so that the docking lock block 23 can move along a predetermined trajectory during the closing process, ensuring the smooth closure of the trunk lid, avoiding misalignment or jamming, and improving the convenience and safety of use.
[0039] Working principle: When using the device, first fix the fixed plate 3 to the middle of the bottom plate 1, then fix the shock-absorbing cylinder 18 to both sides of the fixed plate 3, then install the shock-absorbing spring 19 and the movable plate 20 inside the shock-absorbing cylinder 18, and then fix the washer 22 to the outside of the installation port 21, so as to complete the installation of the shock-absorbing assembly. By arranging the shock-absorbing cylinder 18 on both sides of the fixed plate 3, when the docking lock block 23 collides with the fixed plate 3 and is locked, the shock-absorbing cylinder 18 will absorb the impact and then slowly release it, thereby alleviating the impact force generated when the docking lock block 23 collides with the fixed plate 3, which is beneficial In order to reduce noise and extend the service life of the lock, the stability of the zipper structure is improved by the gasket 22, and the driving motor 13 is controlled by the external button. The driving motor 13 drives the screw rod 12 to operate through the coupling, thereby driving the slider 14 to move inside the limiting slide groove 11, and the slider 14 drives the connecting rod 15 to move, and the connecting rod 15 drives the pushing rod 8 to move, and finally the pushing rod 8 drives the latch 7 to move. When the trunk is closed, the latch 7 passes through the fixed plate 3 and the docking lock block 23, thereby realizing the function of automatic locking, which is very simple and efficient.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
