Abstract
The invention discloses a door closing-opening indication device of an automobile door lock. The door closing-opening indication device comprises a claw support (1), a ratchet wheel (2) and a button microswitch (3), wherein a ratchet wheel pawl meshing transmission chamber (4) and an electric member chamber (5) which are isolated are arranged on the claw support (1); the ratchet wheel (2) is arranged inside the ratchet wheel pawl meshing transmission chamber (4); the button microswitch (3) is arranged inside the electric member chamber (5); and the ratchet wheel (2) is linked with the button microswitch (3) through a power transmission mechanism arranged inside the electric member chamber (5). As the ratchet wheel pawl meshing transmission chamber and the electric member chamber are independent and are not communicated mutually, the button microswitch can work in a relatively independent area, thereby being beneficial to meeting the working environment required highly by the electric member; the electric member can work smoothly in a comfortable environment, the dust or the greasy area where the ratchet wheel is meshed with the pawl is avoided; the working reliability of the electric member is improved sufficiently; and the assurance in safe running of the automobile is provided.
Description
Technical field
The present invention relates to a kind of automobile door lock, particularly a kind of switch door indicating device of automobile door lock.
Background technology
Automobile door lock can be used for opening or closing of arrangements for automotive doors, and the deixis of door lock can illustrate the state that opens or closes of arrangements for automotive doors, and existing door lock indicating device comprises electrical appliance part and mechanical part; Electrical appliance part and the mechanical part same working region that coexists, this regional work environment is more abominable, and long-term work is in this zone; Dust or greasy when big; The switch indicating device is easy to lose efficacy, and can't indicate arrangements for automotive doors and open, and still closes.If arrangements for automotive doors closes when not in place, there is potential safety hazard in the driving process.
Summary of the invention
The present invention is in order to solve weak point of the prior art, a kind of good reliability is provided, is not vulnerable to dust or the greasy and switch door indicating device automobile door lock that damages.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of switch door indicating device of automobile door lock; Comprise pawl bearing 1, ratchet 2 and button microswitch 3, said pawl bearing 1 is provided with separated click engaged transmission chamber 4 and electric component chamber 5, and ratchet 2 is positioned at click engaged transmission chamber 4; Button microswitch 3 is positioned at electric component chamber 5, and ratchet 2 is through being located at power drive mechanism and 3 interlocks of button microswitch in the electric component chamber 5.
Said power drive mechanism comprises first spline 6 and sleeve pipe 7 that is positioned at electric component chamber 5 that the centre of gyration place of ratchet 2 is provided with; One end of sleeve pipe 7 is provided with second spline 8 that is in transmission connection with first spline 6; Sleeve pipe 7 sidepieces are provided with cam 9, contact button 10 contact matching on the arc surface of cam 9 and the button microswitch 3.
Because the regional dust of ratchet and pawl engaged transmission or greasy bigger; So the present invention becomes separate, disconnected two chambers with the click engaged transmission chamber on the pawl bearing with the electric component chamber design; Make the button microswitch in relatively independent zone, work; Help satisfying the bad border of work that electrical appliance is had relatively high expectations, assurance electrical equipment is worked in the environment of easiness smoothly, avoids dust or greasy bigger ratchet, ratchet mesh regional; Fully improve the reliability of electric component work, for the safety traffic of automobile provides safeguard.
Power drive mechanism in the electric component chamber adopts the mode of spline transmission and cam mechanism, is easy to processing and manufacturing and good reliability, and car door is in opening or closing process; Snap close on the car body drives ratchet and rotates, first spline on the ratchet and second spline on the sleeve pipe coaxial rotation transfer torque that is meshing with each other, and the cam of cover tube side part is rotation thereupon also; Arc surface on the cam is the contact button on the pressing button microswitch in rotation process; Contact button is under action of cam, and the retraction state when free state when existence is stretched out and pressurized has had this two states; Two kinds of electrical signals of button microswitch output switching; Utilize the switching of this electrical signal, indicating arrangements for automotive doors is to open, and still closes.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an A-A sectional view in the middle of Fig. 1;
Fig. 3 is the sketch mapes of component of the present invention under disassembled form.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The switch door indicating device of a kind of automobile door lock of the present invention; Comprise pawl bearing 1, ratchet 2 and button microswitch 3, pawl bearing 1 is provided with separated click engaged transmission chamber 4 and electric component chamber 5, and ratchet 2 is positioned at click engaged transmission chamber 4; Button microswitch 3 is positioned at electric component chamber 5, and ratchet 2 is through being located at power drive mechanism and 3 interlocks of button microswitch in the electric component chamber 5.
Power drive mechanism comprises first spline 6 and sleeve pipe 7 that is positioned at electric component chamber 5 that the centre of gyration place of ratchet 2 is provided with; One end of sleeve pipe 7 is provided with second spline 8 that is in transmission connection with first spline 6; Sleeve pipe 7 sidepieces are provided with cam 9, contact button 10 contact matching on the arc surface of cam 9 and the button microswitch 3.
Because the regional dust of ratchet 2 and ratchet (not shown) engaged transmission or greasy bigger; Click engaged transmission chamber 4 on the pawl bearing 1 is separate, disconnected with electric component chamber 5; Make button microswitch 3 in relatively independent zone, work; Help satisfying the bad border of work that electrical appliance is had relatively high expectations, assurance button microswitch 3 is worked in the environment of easiness smoothly, avoids dust or greasy bigger ratchet 2, ratchet mesh regional; Fully improve the reliability of electric component work, for the safety traffic of automobile provides safeguard.
Car door is in opening or closing process, and snap close on the car body drives ratchet 2 and rotates, first spline 6 on the ratchet 2 and second spline 8 on the sleeve pipe 7 coaxial rotation transfer torque that is meshing with each other; The cam 9 of sleeve pipe 7 sidepieces also rotates thereupon, and the arc surface on the cam 9 is the contact button on the pressing button microswitch 3 10 in rotation process, and contact button 10 is under the effect of cam 9; Retraction state when free state when existence is stretched out and pressurized; This two states has been arranged, and two kinds of electrical signals of button microswitch 3 output switchings utilize the switching of this electrical signal; Indicating arrangements for automotive doors is to open, and still closes.
