Below in conjunction with the accompanying drawings 6 and accompanying drawing 7 the specific works process of car door auxiliary door lock device of the present invention is described, described car door assists
Door lock assembly is as described above by installing lower block block assembly the 2, first pull bar 3, countershaft assembly 4 on car door assembly 1, second drawing
Bar 5, upper rear side block assembly the 6, the 3rd pull bar 7 and side block block assembly 8 of going forward are constituted, by lower block block assembly the 2, first pull bar 3, in
Between axle assembly the 4, second pull bar 5, upper rear side block assembly the 6, the 3rd pull bar 7 and side block block assembly 8 of going forward constitute one group of connecting rod locking
Mechanism realizes the auxiliary locking to car door, and reaches to newly increase three connection lock points at car door and gusset doorframe when locking, with existing
Body hinge and common door lock act on jointly, further strengthen the locking intensity of car door, make driver's cabin when by greater impact, can have
Prevent car door from deforming to effect.Concrete, when car door auxiliary door lock device lockup state to be in, it is rotated down clockwise and pulls institute
State the Internal handle 12 on countershaft assembly 4, drive the rotating disk 10 on countershaft assembly 4 to rotate clockwise, thus to being connected to rotating disk 10
First pull bar 3 at rear portion provides thrust, the first pull bar 3 promote lower block block assembly 2 to be turned out (counterclockwise) and make its locking rod outside
Stretching out, second pull bar 5 to being connected to rotating disk 10 front portion that rotates clockwise of rotating disk 10 provides thrust simultaneously, the second pull bar 5 promote
Upper rear side block assembly 6 is rotated up (clockwise) makes its locking rod protrude upward, go up simultaneously rear side block assembly 6 be rotated up will
There is provided pulling force backward to the 3rd pull bar 7, the 3rd pull bar 7 pull side block block assembly 8 of going forward to be rotated up (clockwise) and make its locking
Bar protrudes upward, so when Internal handle 12 rotate clockwise downwards carry out car door locking time, described lower block block assembly 2, upper rear side block
Assembly 6 and the locking rod gone forward on side block block assembly 8 simultaneously the lower rear side of car door, on rear side and upper forward position stretch out in door frame
Locking hole in, thus add at car door and gusset doorframe, increased three locked points newly, improve the anticollision deformation intensity of car door,
As shown in Figure 6.
Same reason, when car door auxiliary door lock device opening to be in, rotates up counterclockwise and pulls described countershaft assembly
Internal handle 12 on 4, drives the rotating disk 10 on countershaft assembly 4 to rotate counterclockwise, thus draws to be connected to rotating disk 10 rear portion first
Bar 3 provides pulling force, the first pull bar 3 pull lower block block assembly 2 inwardly to rotate (clockwise) and make its locking rod to contract, turn simultaneously
Second pull bar 5 to being connected to rotating disk 10 front portion that rotates counterclockwise of dish 10 provides pulling force, the second pull bar 5 pull upper rear side block total
Become 6 rotate down (counterclockwise) make its locking rod to contract, go up simultaneously on rear side of rotating down of block assembly 6 will be to the 3rd pull bar 7
Thrust backward is provided, by the 3rd pull bar 7 promote side block block assembly 8 of going forward rotate down (counterclockwise) make its locking rod to contract,
So when Internal handle 12 upwards rotate counterclockwise carry out car door opening time, described lower block block assembly 2, upper rear side block assembly 6 and go forward
Locking rod on side block block assembly 8 is contracted in the inside of car door assembly simultaneously, it is ensured that car door normally-open, as shown in Figure 7.
Below it is only that the preferred embodiment of the present invention is described, technical scheme is not limited to this, this area
Any known deformation that technical staff is made on the basis of the major technique of the present invention is conceived broadly falls into the present invention claimed technology model
