Abstract
The utility model relates to a screw improved structure for vehicle central control door locks, which belongs to the technical field of locks, particularly to a screw improved structure for vehicle central control door locks applied to various vehicles such as cars, trucks, etc. The utility model has the technical scheme that the middle section of a screw is provided with screw threads, and both end parts form a columnar shape. The screw is provided with the screw threads only in the middle section, so after realizing the unlocking and locking control of door locks, the utility model does not continue to drive a slide block to move along the axial line of the screw, which causes the slide block to push the screw seat and break the screw seat or a casing by pushing and pressing. The utility model has the advantages of improved reliability and high durability.
Description
The utility model relates to the technical field of lock, refers in particular to a kind of screw rod that is used for the automobile centring control door lock of various vehicles such as car, truck and improves structure.
Automobile is development by leaps and bounds along with science and technology development; Through the times short by one, two a century, from initial very simple and crude four-wheeled, develop into nowadays, various, multiple functional automobile all can buy on market; Now, it is land transportation, transportation means as people, is used by increasing people.As the automobile centring control door lock of an automobile part,, wait the earthshaking effect of bringing into play for the safety of protecting automobile though its composition that occupies in the value of automobile is very little; But. there is structural defective in just all in the market automobile centring control door locks, as its screw rod in order to transmission, the one end is installed in the housing by screw bolt seat, motor in the housing rotates by the gear driven screw rod, when screw rod rotates, screw thread on it makes the slide block that cooperates with it move along screw axis, thereby the tapered end pole socket is also moved along screw axis, move and drive the tapered end bar that is attached thereto, realization is to the open and close control of door lock, after the open and close control that realizes door lock, the motor outage; Because the inertia of motor can not stop operating immediately, also can continue to drive screw rod and rotate, make slide block continue the pushing screw bolt seat; So, being easy to will be bad with screw bolt seat or housing pushing, and makes the control door lock lose its function; Like this, make troubles to the user on the one hand, also increased user's use cost on the other hand.
The purpose of this utility model provide a kind of screw rod only therebetween part threaded, can not with screw bolt seat and the housing pushing be bad, reliability is high, the screw rod of long-lived automobile centring control door lock improves structure.
The utility model is achieved by the following technical solution: screw bolt seat is fastened in the groove of housing, screw rod one end is fixed on the housing by screw bolt seat, its other end is captiveed joint with gear, supporting base in the circular hole of this end of screw rod and the draw-in groove that is installed in housing is connected, the tooth of gear is meshed with tooth on the motor output shaft that is fixed in the housing, slide block matches with thread segment on the screw rod, and the tapered end pole socket places in the guide groove of housing; The interlude of screw rod has screw thread, and two end portions is a column; Screw rod one end has the projection on a circular hole and the screw bolt seat to socket-connect, and the cylinder of the other end cooperates with circular hole on the screw bolt seat; There are two projections corresponding on the slide block with the projection on the tapered end pole socket.
The utility model, can not continue to drive slide block and move along screw axis, thereby make slide block withstand screw bolt seat after the open and close control that realizes door lock because of screw rod only partly has screw thread therebetween, and screw bolt seat or housing pushing is bad; Its reliability improves greatly, durable in use.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model exploded drawings
Accompanying drawing 2 is the utility model screw rod 1 local figure
Accompanying drawing 3 is the utility model screw bolt seat 3 block diagrams
See accompanying drawing 1,2,3,4, the utility model includes screw rod 1, supporting base 2, screw bolt seat 3, gear 4, motor 5, slide block 6, tapered end pole socket 7, housing 8 screw bolt seats 3 are fastened in the groove 82 of housing 8, screw rod 1 one ends are fixed on the housing 8 by screw bolt seat 3, its other end is captiveed joint with gear 4, supporting base 2 in the circular hole 11 of screw rod 1 this end and the draw-in groove that is installed in housing 83 is connected, the tooth of gear 4 be fixed on housing 8 in motor 5 output shafts on tooth be meshed, slide block 6 matches with thread segment on the screw rod 1, and tapered end pole socket 7 places in the guide groove 81 of housing 8; The interlude of screw rod 1 has screw thread, and two end portions is a column; Screw rod 1 one ends have a circular hole 11 and projection 21 on the screw bolt seat 2 to socket-connect, and the cylinder of the other end cooperates with circular hole 31 on the screw bolt seat 3; There are two projections 61 corresponding on the slide block 6 with the projection 71 on the tapered end pole socket 7.
When using the utility model, rotate by switch control motor 5, because the tooth on the tooth of gear 4 motor 5 output shafts interior with being fixed on housing 8 is meshed; Therefore, gear 4 is being driven by motor 5 and is rotating; Because screw rod 1 is captiveed joint with gear 4; So when gear 4 rotated, screw rod 1 also can be along with rotation, the slide block 6 that matches with thread segment on the screw rod 1 is along with the rotation of screw rod 1 is moved along screw rod 1 axis; Two projections 61 on the slide block 6 withstand the projection 71 on the tapered end pole socket 7, and tapered end pole socket 7 is moved thereupon; When motor 5 was just changeing, slide block 6 moved to the direction away from gear 4, and drove tapered end pole socket 7 and move thereupon, and when slide block 6 will move on to screw tip on the screw rod 1, the lateral margin of tapered end pole socket 7 was withstood no longer mobile by housing 8; At this moment, the tapered end bar that links to each other with tapered end pole socket 7 is opened lock; Projection 61 on the slide block 6 backs down the projection on the tapered end pole socket 7 71, and moves to the opposite side of the projection 71 on the tapered end pole socket 7; The switch of control motor 5 cuts out; But because the inertia of motor 5, slide block 6 continues to move to screw tip on the screw rod 1 along screw rod 1 axis by original direction; But because the interlude of screw rod 1 has screw thread, and two end portions is a column; Like this, although motor 5 may be rotated further, because slide block 6 has moved to the screw tip on the screw rod 1, screw rod 1 forms idle running, and slide block 6 is no longer mobile, can not cause slide block 6 to withstand screw bolt seat 3, and screw bolt seat 3 or housing 8 pushings is bad; When motor 5 counter-rotatings, slide block 6 also oppositely moves, because when motor 5 was just changeing, the projection 6 on the slide block 6 had moved to the opposite side of the projection 71 on the tapered end pole socket 7, makes slide block 6 drive tapered end pole socket 7 and also oppositely moves, thereby will pin.
