Description
Technical field
The utility model is related to a kind of locking devices, particularly a kind of vehicle door locking device.
Background technology
Existing vehicle door locking device is divided to active and passive two major class, and active locking device is simple in structure but high failure rate,
Therefore frequently with the folding of passive locking device control car door, but passive locking apparatus structure is relative complex, multi-party for vehicle
It is poor to impact vibration environmental suitability.
The existing passive locking device of car door is in addition to vibrationproof difference, and also there are overall dimensions are long, matching relationship is multiple
The shortcomings that miscellaneous, and locking process is not smooth.
Utility model content
Purpose of utility model：The utility model provides a kind of passive locking of car door, which can be with dimensional structure
It is relatively small, can in the environment of the multi-direction impact vibration of vehicle effective locking car door, avoid the occurrence of the accident surprisingly opened the door.
Utility model content：A kind of car door locking device, latching slot are fixed on the beam mechanism of car door load carrier
On；Gear frame is mounted on guide post, can be slided along guide post, and band folder is fastenedly connected compression transmission belt with gear frame；Latch hook is hinged
On door frame is taken, connected between gear frame and latch hook by connecting plate；Transmission belt moves, and drives band folder and gear frame, gear frame
Latch hook is promoted by connecting plate, in no arrival locking groove location, door frame is taken in latch hook drive, realizes the action of open and close door, reaches
During shutdown position, transmission belt movement gear frame promotes connecting plate, and the hook on latch hook is transferred to latching slot, while connecting plate is translatable
To close to vertical position, resetting spring pushes down gear frame, realizes locking.
Locking in place after, latch hook lateral displacement is blocked slot limitation, and vertical deviation is connected plate limitation, and resetting spring pushes down
Door frame is taken, mechanism is not influenced be subject to each side's impact vibration, realizes that the more degree of freedom limits.
During unlocking motion, transmission belt movement drives band folder and gear frame, and gear frame pulls latch hook to produce lock by connecting plate
After locked groove, latch hook promotion takes door frame and realizes door opening action.After connecting plate pulls latch hook to produce certain angle downwards, under latch hook
Side is against on the vertical plate of guide post one side, and latch hook holds connecting plate, and connecting plate limitation gear frame slides to prevent on guide post multiple
Position spring overvoltage.
Advantageous effect：Car door locking device provided by the utility model only constrains longitudinal movement compared with original door lock
Without situation about constraining catenary motion, can in the environment of vehicular impact all directions impact vibration effective locking vehicle doorn, keep away
Exempt from the accident surprisingly opened the door occur；And it is smaller that whole device length direction occupies size

Specific embodiment
As shown in Fig. 1~5, a kind of car door locking device, latching slot 1 is fixed on beam mechanism, and latch hook 2, which is hinged on, to be taken
On door frame 5；The card slot 22 opened up on latch hook 2 is stretched into 3 one end of connecting plate, is rotatably connected on latch hook 2, the other end is rotatably connected on
On gear frame 4；Gear frame 4 is mounted on guide post 7 and can be slided along guide post 7, and guide post 7, which is fixed on, to be taken on door frame 5；Resetting spring
6 are socketed on gear frame 4 on the guide post 7 of one side at door closing, and band folder 8 is fastenedly connected with gear frame 4 compresses transmission belt 9.
As shown in Figure 4 and Figure 5, the one end of latch hook 2 at door closing is equipped with hook 21 upward, is provided in hook 21
Idler wheel 211,2 other end of latch hook, which is hinged on, to be taken on door frame 5, card slot 22 be located at hook 21 and latch hook 2 and take 5 junction of door frame it
Between.
During closing of the door, transmission belt 9 drives gear frame 4, and toward movement at door closing, gear frame 4 is promoted by connecting plate 3
Latch hook 2 moves, and latch hook 2 is further driven to take door frame 5 toward moving at door closing, when reaching locked position, idler wheel 211 along
1 side wall of latching slot rolls so that the hook 21 of latch hook 2 is transferred to latching slot 1；At this point, as shown in fig. 7, since the side of card slot 22 limits
It rotates and stops when system, connecting plate 3 turn to vertical position, 4 one side of the gear frame spring 6 that is reset pushes down opposite side by connecting plate 3
Limiting it follows transmission belt 9 to continue to slide, and entire locking process terminates at this time；When connecting plate unlocks, transmission belt 9 drives gear frame
4 move to car door opening direction, and gear frame 4 is further driven to connecting plate 3 and pulls latch hook 2 so that the hook 21 of latch hook 2 departs from lock
Locked groove 1；The drive of latch hook 2 is taken door frame 5 and is moved toward car door opening direction；As shown in Figure 2 and Figure 5, pulled when latch hook 2 is connected plate 3
Its downside props up the vertical plate 71 that one side of the guide post 7 at door closing is set when being swung down to certain position, locks at this time
Hook 2 is moved and limited, and can not be rotated down again, and latch hook 2 holds connecting plate 3, and connecting plate 3 further limits the slip of gear frame 4,
So as to prevent gear frame 4 excessive to the pressure of resetting spring 6, resetting spring 6 is caused to be damaged due to overvoltage.
