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 gate indicating device of automobile door lock.
Background technology
Automobile door lock can be used for opening or closing of arrangements for automotive doors, the deixis of door lock can illustrate the state that opens or closes of arrangements for automotive doors, 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 severe, and long-term work is in this region, dust or greasy when larger, switch indicating device is easy to lose efficacy, and cannot indicate arrangements for automotive doors and open, and still closes.If arrangements for automotive doors closes time not in place, in driving process, there is potential safety hazard.
Summary of the invention
The present invention is in order to solve weak point of the prior art, provides a kind of reliability by force, not to be vulnerable to dust or switch gate the indicating device greasy and 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 gate indicating device of automobile door lock, comprise pawl bearing 1, ratchet 2 and button microswitch 3, described pawl bearing 1 is provided with separated click engaged transmission chamber 4 and electric component chamber 5, ratchet 2 is positioned at click engaged transmission chamber 4, button microswitch 3 is positioned at electric component chamber 5, and ratchet 2 links by the power drive mechanism and the button microswitch 3 that are located in electric component chamber 5.
Described power drive mechanism comprises the first spline 6 and the sleeve pipe 7 that are positioned at electric component chamber 5 that the centre of gyration place of ratchet 2 arranges, one end of sleeve pipe 7 is provided with the second spline 8 being in transmission connection with the first spline 6, sleeve pipe 7 sidepieces are provided with cam 9, and the arc surface of cam 9 contacts cooperation with the contact button 10 on button microswitch 3.
Due to the region dust of ratchet and pawl engaged transmission or greasy larger, so the click engaged transmission chamber on pawl bearing is become separate, disconnected two chambers with electric component chamber design by the present invention, button microswitch is worked in relatively independent region, be conducive to meet the bad border of work that electrical appliance is had relatively high expectations, guarantee electrical equipment is worked smoothly in easy environment, avoid dust or greasy larger ratchet, ratchet mesh regional, fully improve the reliability of electric component work, for the safety traffic of automobile provides safeguard.
Power drive mechanism in electric component chamber adopts the mode of spline drived and cam mechanism, be easy to processing and manufacturing and reliability is strong, car door is opening or closing in process, snap close on car body drives ratchet to rotate, the intermeshing coaxial rotation transmitting torque of the second spline on the first spline on ratchet and sleeve pipe, the cam of cover tube side part also rotates thereupon, arc surface on cam is pressed the contact button on button microswitch in rotation process, contact button is under the effect of cam, retraction state when free state when existence is stretched out and pressurized, there is this two states, button microswitch output is logical, disconnected two kinds of electrical signals, utilize the logical of this electrical signal, disconnected, indicating arrangements for automotive doors is to open, still close.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A sectional view in the middle of Fig. 1;
Fig. 3 is the schematic diagrames of component of the present invention under disassembled form.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the switch gate 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, ratchet 2 is positioned at click engaged transmission chamber 4, button microswitch 3 is positioned at electric component chamber 5, and ratchet 2 links by the power drive mechanism and the button microswitch 3 that are located in electric component chamber 5.
Power drive mechanism comprises the first spline 6 and the sleeve pipe 7 that are positioned at electric component chamber 5 that the centre of gyration place of ratchet 2 arranges, one end of sleeve pipe 7 is provided with the second spline 8 being in transmission connection with the first spline 6, sleeve pipe 7 sidepieces are provided with cam 9, and the arc surface of cam 9 contacts cooperation with the contact button 10 on button microswitch 3.
The first spline 6 and sleeve pipe 7 all adopt plastic coatings to make, and material selection Hytrel 5526 (Dupont of E.I.Du Pont Company) allows to use suitable material substitution.
Due to the region dust of ratchet 2 and ratchet (not shown) engaged transmission or greasy larger, click engaged transmission chamber 4 and electric component chamber 5 on pawl bearing 1 are separate, disconnected, button microswitch 3 is worked in relatively independent region, be conducive to meet the bad border of work that electrical appliance is had relatively high expectations, guarantee button microswitch 3 is worked smoothly in easy environment, avoid dust or greasy larger ratchet 2, ratchet mesh regional, fully improve the reliability of electric component work, for the safety traffic of automobile provides safeguard.
Car door is opening or closing in process, snap close on car body drives ratchet 2 to rotate, the intermeshing coaxial rotation transmitting torque of the second spline 8 on the first spline 6 and sleeve pipe 7 on ratchet 2, the cam 9 of sleeve pipe 7 sidepieces also rotates thereupon, arc surface on cam 9 is pressed the contact button 10 on button microswitch 3 in rotation process, contact button 10 is under the effect of cam 9, retraction state when free state when existence is stretched out and pressurized, there is this two states, button microswitch 3 outputs are logical, disconnected two kinds of electrical signals, utilize the logical of this electrical signal, disconnected, indicating arrangements for automotive doors is to open, still close.
