Abstract
The utility model relates to a waterproof electric lock of a vehicle door, which comprises a lower cover with an upepr cover, wherein, the bottom of the lower cover is provided with a containing chamber. A motor is arranged in the containing chamber, the output terminal of the motor is connected with a transmission gear set, and an output gear of the gear set is engaged with a rack bar of a sliding rod. The lower end of the containing chamber is provided with more than one small hole. When accumulated water is stored in the electric door lock, the accumulated water in the door lock is extruded from the small holes through the telescopic actions of the sliding rod, which assures the dryness in the door lock at any moment in order to assure the normal using of the appliance components of the electric door lock.
Description
The utility model relates to a kind of electric door lock for vehicle, is meant a kind of electric door lock with water-proof function especially.
The structure of the electric door lock for vehicle that uses as shown in Figure 3 at present, it includes a loam cake, be provided with a room in the bottom of lower cover, be equiped with a motor in the room, the output of this motor connects a driving gear set, the output gear of this gear train is engaged in the tooth bar of slide bar, and it is flexible to drive slide bar with this, the action of unblanking or shutting.This kind electric door lock for vehicle in use finds to exist following defective, because the structure of arrangements for automotive doors is not a complete closed, at rainy weather, when the driver scrubs vehicle body and automobile when in darker water, travelling, what the capital had that water prolongs car door does not seal the place, as door and window, enter in the interlayer of car door, and enter in the door lock along with the slide bar action of door lock.Exist in the car door interlayer and behind rainwater access door locker layer, also assemble sometimes, though general car door is considered this kind situation when design, thereunder be provided with drain hole, but this drain hole is got rid of not smooth because of long-term unclean use sometimes even is stopped up, all can there be the phenomenon of ponding to take place in use for some time at car door in such cases, this ponding also can enter in the electric door lock when the action of above-mentioned electric door lock slide bar.Because the motor of above-mentioned electric door lock is provided in a side of in the room of lower cover, and this room below is a closed state, so the water that enters in the door lock is to discharge automatically, therefore have influence on the operate as normal of electric elements in the electric door lock widely, cause latch failure to take place, and even have influence on the normal keying of car door.
The purpose of this utility model is to be to provide a kind of electric door lock for vehicle, makes it to have water-proof function, when entering ponding in the door lock, this ponding can be discharged automatically, to guarantee the operate as normal of door lock electric elements.
The purpose of this utility model is achieved in that a kind of electric door lock for vehicle with water-proof function, include a loam cake and lower cover, be provided with a room in the bottom of lower cover, be equiped with a motor in the room, the output of this motor connects a driving gear set, the output gear of this gear train is engaged in the tooth bar of slide bar, it is characterized in that the lower end of described room is provided with more than one aperture.
The purpose of this utility model also can be realized that by following measure described hole diameter be the best for 1.5～3 millimeters, and an end of motor can be provided with temperature-sensitive element.
Operating principle of the present utility model and effect are, owing to be provided with a small through hole in the lower end of room, when having ponding in the electric door lock, expanding-contracting action by slide bar, ponding in the door lock is gone out from this small through hole extruding, so can very fast discharge with the ponding in the door lock, guarantee the drying in the door lock at any time, to guarantee the normal use of electric door lock electric component.
In sum, the utility model has been realized the automatic discharge of ponding in the electric door lock with the simplest a kind of structure, thereby makes electric door lock have a kind of function of waterproof, guarantees the operate as normal of the electric elements in the door lock, and prolongs the application life of door lock.
The explanation of accompanying drawing drawing
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the structural representation of existing electric door lock.
Face directly will be in conjunction with the embodiments and accompanying drawing to describe the utility model in detail as follows;
See also shown in Figure 1ly, the utility model includes a loam cake and lower cover 1, and the bottom of lower cover 1 then is provided with a room 10, is equiped with a motor 2 in the room 10, as the driven by power source of door lock.This motor 2 connects a control device with lead, and just changeing or reversing by this control device control motor 2, this motor 2 just change or reverse flip flop equipment can be by a microswitch 4 control, this microswitch 4 is located in the alcove 11 of lower cover 1 upper end, and microswitch 4 is connected on the control device by lead.
The output of this motor 2 connects a driving gear set 5, this gear train 5 be by the gear wheel 51 that is connected in motor 2 and one and these gear wheel 51 pinion mates 52 constitute, pinion 52 is connected in the tooth bar 61 of slide bar 6, when motor 2 driven gears are made forward or backwards rotation, by pinion 52 drive slide bars 6 do overhanging or in contract, finish opening or closing of door lock.
Most important characteristic of the present utility model is to be provided with more than one aperture 7 in the lower end of the room 10 of lower cover 1, these little and above-mentioned room 10 conductings, and diameter the best of this aperture 7 is 1.5～3 millimeters.Excessive as aperture 7 diameters, the ponding in the car door is as easy as rolling off a log to be entered from here.In the present embodiment, the diameter of aperture is 2 millimeters, and this aperture 7 preferably is arranged at opposite one side of stretching out direction with slide bar 6.
The utility model electric door lock is when being assembled on the car door, is door lock is fixed on the wallboard in the car door Sandwiched door band.If ponding or rainwater that water in the inflow car door interlayer or collection are stored in the car door interlayer enter in the door lock, expanding-contracting action along with door lock slide bar 6, driving the slide bar 6 outer resilient dust boot that are arranged with shrinks, make the air in the lock be compressed, and then the aperture 7 of ponding from room 10 lower ends of loam cake 1 is extruded.And because the aperture of this aperture 7 is less, under the effect that does not have external pressure, ponding is difficult to again be entered in the door lock by aperture.And along with door lock opens or closes continuous motion, the ponding in the door lock can be discharged automatically again, make and remain drying in the door lock.
In addition,, can establish a temperature protection switch or current protection switch, make motor under situation about meeting accident, realize power-off protection at the terminals of room 10 inner motors 2.
In sum, the utility model adopts the simplest structure, make to the utlity model has a kind of water-proof function, and then can not only guarantee the door lock operate as normal, but and the earth prolong application life of the present utility model.
