Description
Technical Field
The utility model relates to an electric actuator institutional advancement that vehicle rearview mirror used belongs to vehicle parts design field.
Background
At present, an electric rearview mirror adjusting mechanism used for a vehicle is generally connected to a rearview mirror supporting plate through a connecting plate by a driver. The motor outputs power to drive and change the positions of the connecting plate and the supporting plate in the transverse direction and the vertical direction, and finally the dynamic adjustment of the rearview mirror is realized.
The existing connecting plate connected with a driver only adopts two racks for supporting and driving. The two racks are not supported in the contraposition (opposite to the horizontal position). In the running process of the vehicle, the connecting plate is in a suspended state in the transverse direction and the vertical direction, so that large shaking can be generated correspondingly. During shaking, on one hand, the rack is pulled to drive the gear mechanism connected with the rack to abnormally operate, so that the service life of the gear is shortened, and the gear is damaged when the gear is serious; on the other hand, such a long time may even cause the mirror lens to fall off.
The defects of the prior art can directly improve the maintenance cost, can also send larger noise in the process of driving the vehicle, and can also lead the driver not to correctly judge the road condition at the side rear part of the vehicle by greatly shaking the rearview mirror, thereby increasing the occurrence probability of traffic accidents.
In view of this, the present patent application is specifically proposed.
SUMMERY OF THE UTILITY MODEL
Driver for vehicle rear-view mirror, design aim at solve the problem that above-mentioned prior art exists and propose four group's rack mechanism that is the cross and arranges to improve rear-view mirror drive and connection structure's whole steadiness, and then reach the improvement departure point that reduces cost of maintenance.
In order to achieve the above design purpose, the driver for the vehicle rearview mirror mainly comprises the following design:
the driver is connected with the rearview mirror supporting plate through a connecting plate, the driver comprises an upper shell and a lower shell which are connected into a whole and form an inner cavity, and two groups of first racks and second racks which are vertically arranged are arranged on the lower shell.
The main difference from the prior art is that a first auxiliary rack and a second auxiliary rack are arranged opposite to the first rack and the second rack;
the top ends of the first rack, the second rack, the first auxiliary rack and the second auxiliary rack are all provided with positioning columns assembled with the connecting plate;
the first auxiliary rack and the second auxiliary rack are respectively meshed with the gear driven by the auxiliary clutch.
According to the basic design scheme, the driver adopts a built-in and symmetrically arranged four-rack linkage mechanism, namely four racks in a cross arrangement structure are adopted between the connecting plate and the lower shell for supporting. Under first rack, second rack drive at its driving motor, at horizontal or vertical go up the adjustment in-process, provide effective support by the supplementary rack of counterpoint, consequently when the rear-view mirror rocks because of the automobile goes the production, all have the rack to support on four directions of driver to can reduce rocking, the noise reduction still of lens.
The connecting plate assembles the reference column at above-mentioned 4 rack tops simultaneously, and the reference column can act as the rotation center pin. For example, in the vertical adjustment process, no matter any rack rises or descends, the connecting plate rotates by taking the positioning column as a rotating shaft, so that the connecting plate cannot incline when rotating, and the connecting structure of the driver and the connecting plate is more stable.
Furthermore, the lower shell is respectively provided with a mounting groove for assembling the first rack, the second rack, the first auxiliary rack and the second auxiliary rack, and the mounting groove is provided with a transverse limiting mechanism and a vertical limiting mechanism.
The 4 racks are respectively arranged in the mounting grooves of the lower shell, and the limiting mechanism can effectively prevent the racks from shaking transversely. Particularly in the vertical adjustment, because the movement directions of the two racks in the alignment are just opposite, the lower limit of one rack in the alignment is alternatively used as the upper limit of the other rack, so that one-to-one synchronous limit is formed.
In order to effectively block the rack from violent movement, the auxiliary clutch is internally provided with a damping device.
In addition, two auxiliary clutches for driving the first and second auxiliary racks may be installed on the fixed plate on the lower case.
In conclusion, the application has the advantages and beneficial effects that:
1. the existing two-rack supporting structure is changed, four crossed racks are adopted to support the connecting plate, the racks are respectively meshed with the clutch with the built-in damping device, when the rearview mirror shakes due to automobile running, the racks are supported in four directions of the driver, the left direction, the right direction and the lower direction of the racks are limited, and the damping device inside the clutch can block the connecting plate to move, so that the shaking of the lenses can be reduced, and the noise can be reduced.
2. This application has optimized the product structure, can improve the structure steadiness of product by a wide margin, improves the quality qualification rate of rear-view mirror.
3. The application commonality is strong, and is few to original structural change, has high replaceability, and the cost is lower, is applicable to the upgrading and upgrading of multiple rear-view mirror product.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1, the driver for a rear view mirror of a vehicle includes an upper case 100 and a lower case 200 which are integrally connected and form an inner cavity.
As shown in fig. 2 and 3, two sets of first and second racks 11 and 12 are disposed on the lower housing 200, which are vertically arranged with respect to each other, a first auxiliary rack (13) is disposed on the first rack 11, and a second auxiliary rack 14 is disposed on the second rack 12;
the top ends of the first rack 11, the second rack 12, the first auxiliary rack 13 and the second auxiliary rack 14 are provided with positioning columns 1 assembled with the connecting plate 9.
The upper case 100 and the lower case 200 are assembled together by screws.
Taking the first rack 11 as an example, it is placed in the mounting groove of the lower housing 200, and the left, right, and lower directions of the mounting groove are all provided with a limiting mechanism to prevent the first rack 11 from shaking left and right. In particular, since the movement directions of the first rack 11 and the first auxiliary rack 13 in the alignment are opposite, the lower limit of one rack in the alignment is changed to serve as the upper limit of the other rack.
The first clutch 4 is fixedly connected with the first gear 2 through a central shaft of the first clutch 4, and a damping device is arranged inside the first clutch 4 so as to effectively block violent movement;
