Description
The utility model relates to the fold mechanism of vehicle mirrors, especially electric foldable mechanism.
Automobile rearview mirror is to observe front vehicle in the process of moving for chaufeur, the automobile accessories parts of pedestrian's running state, it is the assurance of guaranteeing safe driving, by adjustment to the back mirror setting angle, can make the visual field of driver's observation to particular orientation, therefore, the importance of back mirror be everybody knows, but back mirror is installed in vehicle two side positions, when vehicle ' in narrower locus or the more complicated occasion of pedestrian, in order not make back mirror and other vehicle, the pedestrian collides and causes vehicle damage or unnecessary dispute, chaufeur is had to stop and with manual mode back mirror is pulled parallel car side position, treat that vehicle is by complicated occasion after, pull back mirror again and set back, like this, the driving time of just having incured loss through delay chaufeur, getting on the bus get off the operation pretty troublesome, the back vehicle is hindered.A kind of back mirror automatic folding machanism is abroad arranged, and it is by the motor outputting power, and the driven wheel speed reduction gearing is realized the auto-folder of back mirror, and its defective at first is: utilize gear drive bulky, noise is big, and transmission stability is relatively poor; Secondly after the mirror shell forwarded the final position to, mechanism lacked the measure of buffering slipping protection.
The purpose of this utility model is to overcome the defective of prior art and provides that a kind of mechanism to be had take up room rear-view mirror shell automatic folding machanism little, stable drive failure-free transmission device be first purpose; It is second purpose that driven rearview mirrors mirror shell automatic folding machanism with the protective effect of auto-folder friction slip is provided simultaneously.
According to above-mentioned purpose; embodiment of the present utility model is: this automatic folding mechanism for electric rear-view mirror; comprise the mirror shell that back mirror is installed; be fixed on the support on the car door body; be provided with motor between mirror shell and support by the master cock actuating; by motor-driven transmission device; it is characterized in that described transmission device is the secondary speed reduction gearing of second-stage worm gear; this speed reduction gearing is realized mirror shell auto-folder and slipping protection by the friction slip mechanism with the mutual drive connection of its formation, is somebody's turn to do and is regulated by the nut and the spring realization friction moment that are located on the screw rod.
The support friction wheel that described friction slip mechanism comprises the mirror shell friction wheel that friction wheel is arranged, be fixed with one with the mirror shell that is sleeved on successively on the screw rod that fixes with the mirror shell, is fixed with one with support, and mirror shell friction wheel is that smooth flat combines with the support friction wheel.
The utility model compared with prior art has following characteristics: it is the deceleration transmission element that (1) transmission device has adopted second-stage worm gear secondary, and its deceleration is effective, and it is little to take up room, and makes compact conformation reasonable, and stable drive is reliable; (2) in the transmission of torque process, adopted friction slip mechanism,, satisfied the needs of mirror shell auto-folder process by controlling their friction moment sizes each other, also make whole transmission device that the effect of buffering slipping protection has been arranged, thereby protected motor and transmission device; (3) the chaufeur operation of needn't getting off is the scalable field range by the actuating master cock as long as be sitting in the operator's compartment on demand like a cork.
Description of drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
To be described in detail again by the embodiment of above-mentioned accompanying drawing below the utility model.
Shown in Fig. 1-2, driven rearview mirrors mirror shell automatic folding machanism comprises the mirror shell (1) that back mirror is installed, and is fixed on the support (2) on the car door body, and the mutually noninterfere of the relative support rotation process of mirror holder is collided, and is only forwarding the final position to, and the mirror shell is just blocked by support.
Be provided with in the sealed chamber that forms by mirror shell (1) and face shield (19) and make mirror the shell auto-folder and the slipping protection mechanism of rotation automatically; entire mechanism is driven friction slip mechanism at last through the secondary speed reduction gearing of the second-stage worm gear of transmission device and is realized folding and slipping protection by motor (15) outputting power of master cock actuating.The one-level worm screw (14) of the secondary speed reduction gearing of second-stage worm gear links to each other with motor output shaft, after fixing, first-stage worm gear (18) and second-stage worm (16) be sleeved on the transmission shaft (17), transmission shaft two ends close-fitting is in the axis hole of face shield and mirror shell, second-stage worm gear (9) is sleeved on the screw rod (4), and screw rod and mirror shell fix.
The friction slip mechanism that forms mutual drive connection with the second-stage worm gear speed reduction gearing comprises being sleeved on has friction wheel (10), mirror shell friction wheel (12), a support friction wheel (13) on the screw rod (4), wherein second-stage worm gear is that flat department is connected with friction wheel, friction wheel is that circular conical surface combines with mirror shell friction wheel, mirror shell friction wheel is that smooth flat combines with the support friction wheel, and mirror shell friction wheel and mirror shell, support friction wheel and support are inserts and are fixed with one.
Friction wheel; mirror shell friction wheel; positive pressure between the support friction wheel provides by being located at the deformation force that nut (3) on the screw rod and spring (5) produce; also regulated the friction moment between them; the positive pressure of spring can be regulated as required within the specific limits; when regulating friction moment; suppose that motor output torque is M0; friction moment between friction wheel and the mirror shell friction wheel is M1; friction moment between border shell friction wheel and support friction wheel is M2; their threes' relation must meet: M0＞M1＞M2; like this when motor torque is delivered to friction wheel; because M0＞M1＞M2 so M2 is overcome earlier, makes mirror shell friction wheel rotate earlier relative to the support friction wheel; thereby make the relative support of mirror shell carry out auto-folder; rotational angle can change by motor and stop control, and when the mirror shell forwarded the final position of colliding with support to, the mirror shell was blocked; and motor is also remaining in operation this moment; at this moment M0 begins to overcome M1, makes between friction wheel and the mirror shell friction wheel to begin to skid, thereby has protected motor and transmission device.The mirror shell is resetted, reverse by motor and realize.
In order to reduce the loss of the drive torque that end-face friction caused between spring and the second-stage worm gear, therefore, be provided with the steel ball (8) and the packing ring (7) that reduce torque loss between them, a plurality of steel balls are embedded in the annular groove of second-stage worm gear end face, a similar plain thrust bearing.
The connecting wire (6) of the master cock that the motor of transmission device is other with being located at operator's saddle is introduced by support (2), passes screw rod (4) endoporus and is connected with motor, has effectively utilized the space.Assembly technology hole on the support is to stop up (11) sealing.
