The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Shown in Fig. 3 to 5, door latch structure comprises button 10, rod assembly and first, second runner assembly 31,32.As shown in Figure 2, be fixed with button cover 11 on the vehicle backplate (not shown), button 10 is set in the button cover 11.Rod assembly comprises first pull bar 21, second pull bar 22 and the 3rd pull bar 23.First pull bar 21 is a vertical connecting rod, and an end of button 10 is threaded with first pull bar 21, along with carrying or press down on the button 10, drives first pull bar 21 and moves up and down.First runner assembly 31 comprises first tumbler 311 and first fixture 312, and the second turning discreteness 32 comprises that second tumbler 321 and second fixture, 322, the first fixtures 312 all are fixedly connected with inner plate of car door with second fixture 322.First tumbler 311 with in first fixture 312 through vertical relatively turnable connection of bearing pin (not shown) of running through both stack faces.Second tumbler 321 and second fixture 322 are through vertical relatively turnable connection of bearing pin (not shown) of running through both stack faces.Wherein, the lower end of first pull bar 21 is connected in an end of first tumbler 311.The other end of first tumbler 311 is connected in the right-hand member of second pull bar 22, and second pull bar 22 is a drag link.The left end of second pull bar 22 is connected in an end of second tumbler 321, and the other end of second tumbler 321 is connected in the upper end of the 3rd pull bar 23, and the 3rd pull bar 23 is a vertical connecting rod, and the lower end of the 3rd pull bar 23 is connected in the lockable mechanism (not shown).Wherein, on first tumbler 311 and second tumbler 321, be welded with first limiting section 313 and second limiting section 323 respectively towards a side of first fixture 312 and second fixture 322.First limiting section 313 and second limiting section 323 can be square prominent piece.First limiting section 313 and second limiting section 323 make this door lock have limit function, and the concrete course of work is following.
Solid line is that door lock is in the lock state among the figure, and dotted line is that door lock is in released state.During release,, move on first pull bar 21 carrying on the button 10; First tumbler 311 of first runner assembly 31 is rotated counterclockwise; Spur second pull bar 22 simultaneously and move to right, under the drive of second pull bar 22, second tumbler 321 of the second turning discreteness 32 turns clockwise; When second limiting section 323 on second tumbler 321 turns to the position with the EDGE CONTACT of second fixture 322; Second tumbler 321 is by backstop (as shown in Figure 5), thereby stops operating, and carries button 10 on the user can't continue.In the rotation process of second tumbler 321, move on the 3rd pull bar 23, the lockable mechanism (not shown) that links to each other with the 3rd pull bar 23 breaks away from the lock position, realizes release.
Locking process and releasing process are opposite, that is, push button 10, the motion process of rod assembly 20 and first, second runner assembly 31,32 is opposite with the motion process of releasing process, is that the dotted line position from figure moves to solid line position.Wherein, As shown in Figure 4; First tumbler 311 of first runner assembly 31 turns clockwise, and when first limiting section 313 on first tumbler 311 turned to the position with the EDGE CONTACT of first fixture 312, first tumbler 311 was by backstop; Thereby stop operating, the user can't continue push button 10.In the rotation process of first tumbler 311, the 3rd pull bar 23 moves down, and the lockable mechanism (not shown) that links to each other with the 3rd pull bar 23 reaches the lock position, realizes locking.
Limiting section on each runner assembly can carry out spacing in release and locking process respectively to the rotation of runner assembly, make button in restricted portion, to move, and is too high or low excessively when pressing when the position of button is unlikely to mention, thereby easy to use.
Can change the position that is provided with of limiting section according to the difference of the movement travel of button.Shown in Fig. 6 to 8, suppose that the latched position of button is constant, unlocked position changes.To be respectively runner assembly corresponding button stroke be the position of the button of 11mm and 19mm for position B, position C among the figure.Wherein, among Fig. 7,, be locked in all the time on the A of position, therefore, need not the position of first limiting section 313 of first runner assembly 31 on right side is adjusted because the latched position of button is constant.Among Fig. 8, when carrying out release, second tumbler 321 clockwise rotates from latched position A.If the button stroke is 11mm, then second tumbler 321 finally moves on the B of position, and second limiting section 323 that indicates with hollow pot on second tumbler 321 is blocked by second fixture 322.If the button stroke is 19mm, then second tumbler 321 finally moves on the C of position, and second limiting section 323 that indicates with solid slug on second tumbler 321 is blocked by second fixture 322.Can be when door lock be installed, confirm the position of limiting section according to the button of particular type, and the scene is provided with limiting section.
Certainly, the structure of limiting section and position are not limited thereto.For example, limiting section is not limited to square prominent piece, also can be structures such as sheet or strip, also can limiting section be located at the edge of tumbler or fixture, for example is arranged on the flanging structure at edge, as long as can be spacing to it when tumbler rotates.Limiting section can be one-body molded with tumbler or fixture.
Preferably, the height of limiting section is more than or equal to the dry and astringent fixture or the thickness of tumbler, to improve the backstop effect.
Preferably; When tumbler is limited; The contact surface of limiting section and fixture or tumbler is fitted fully, thereby the wearing and tearing that contact surface receives when reducing limiting section as far as possible and repeatedly contacting with fixture or tumbler also can coat the buffer layer of similar PVC layer on the contact surface of limiting section and fixture or tumbler; Not only can reduce wear the abnormal sound that produces in the time of also can eliminating collision.
In addition; Also can be only on the appropriate location of the fixture of rod-pulling type car door lock structure one side or tumbler, two limiting sections be set; Or on the appropriate location of the fixture of rod-pulling type car door lock structure one side and tumbler, a limiting section is being set respectively; The structure of opposite side is constant, can in release or locking process, the motion to button limit equally.Also can on the fixture of a side and tumbler, limiting section and limit sliding chutes be set respectively, in release or the locking process, limiting section moves in limit sliding chutes; The limit point of corresponding release in the two ends of limit sliding chutes and latched position; Therefore, when limiting section moves to the end of limit sliding chutes, limited chute backstop; Stop motion, thus realize spacing to button.
The utility model is through being provided with limiting section on rod-pulling type car door lock structure, thereby the door lock button is spacing, breaks away from from the button cover with the button of avoiding door lock, ease of use is provided, and keeps the door lock good looking appearance.
Though described the utility model with reference to above-mentioned exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.Because the utility model practical implementation and do not break away from the spirit or the essence of utility model in a variety of forms; So be to be understood that; The foregoing description is not limited to any aforesaid details; And should in enclose spirit that claim limited and scope, explain widely, therefore fall into whole variations and remodeling in claim or its equivalent scope and all should be the claim of enclosing and contain.
