Description

A kind of automobile rearview mirror deflector
Technical field:
The utility model relates to a kind of automobile rearview mirror deflector.
Background technology:
Disclosed Granted publication number mainly comprises the base and the shifting ring that are connected with bottom for the CN2568483Y name is called the utility model patent of automobile rearview mirror deflector on deflector of prior art automobile rearview mirror such as the China national intellectual property board web; Be provided with two motors in the described base, be connected with a motor loam cake with copper sheathing on the described motor, described motor by sun shell fragment and coupling link make its rotating shaft in full accord with two and independently drop-gear box be connected, described drop-gear box is made up of gear case lower cover, planetary wheel, center ratch and gear case loam cake, and described drop-gear box is the epicyclic gear transmission mode; The output shaft of described drop-gear box is provided with gear, and described wheel and rack is meshed; Bulb on the described tooth bar and the corresponding connection of fixed orifice on the shifting ring; Described shifting ring is movably arranged on by central stay bearing plate on the connecting element of base, and the point of connection of described shifting ring and connecting element is the fulcrum that shifting ring rotates, described central stay bearing plate be rotatably connected to shifting ring on; Described shifting ring and bottom are provided with dust protecting cap.
Though the deflector of the described prior art automobile rearview mirror of above-mentioned utility model has stable drive, advantage that noise is little, but still there is a weak point in it: the bottom of deflector and the distance between the base have determined the spendable length of deflector middle rack, owing to limit by the integral structure of deflector own, distance in the prior art deflector between bottom and the base is shorter, therefore the tooth bar that adopts is also shorter, thereby causes the defective that rotational angle is little and visual field setting range is narrow of prior art back mirror deflector.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of and can use longer tooth bar, thereby make the automobile rearview mirror deflector that rotational angle is bigger, visual field setting range is wideer.
Technical solution of the present utility model is that a kind of automobile rearview mirror deflector with following structure is provided: it comprises base, be connected bottom on the base, be located at two motors in the base, with the rotating shaft of described two motors two drop-gear boxs of bonded assembly and the shifting ring that is connected with the output shaft of drop-gear box by gear and tooth bar separately; Described shifting ring is movably arranged on the connecting element of base by central stay bearing plate; Corresponding section, bottom with tooth bar on the described bottom is provided with one or two groove.
After adopting above structure, compared with prior art, the utlity model has following advantage: after with the corresponding section, bottom of tooth bar one or two groove being set on the bottom, distance in the utility model between bottom surface one deck of bottom and the base has just increased, the increase of distance can make the utility model use longer tooth bar between bottom and the base, the growth of tooth bar can enlarge the up and down distance of shifting ring, thereby make the rotational angle of the utility model automobile rearview mirror deflector become bigger, it is wideer that visual field setting range also becomes.
The big I of above-mentioned two grooves equates.
The big I of above-mentioned two grooves is unequal.

Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the concrete structure of a kind of automobile rearview mirror deflector of prior art, and the deflector of the utility model automobile rearview mirror also comprises this concrete structure, promptly comprises the base 2 and the shifting ring 6 that are connected with bottom 2; Be provided with two motors 31,32 in the described base 1, be connected with a motor loam cake 11 with copper sheathing 10 on the described motor 31,32, described motor 31,32 by sun shell fragment 12 and coupling link 13 make its rotating shaft in full accord with two and independently drop-gear box be connected, described drop-gear box is made up of gear case lower cover 14, planetary wheel 15, center ratch 16 and gear case loam cake 17, and described drop-gear box is the epicyclic gear transmission mode; The output shaft of described drop-gear box is provided with gear 4, and described gear 4 is meshed with tooth bar 5; Fixed orifice 18 corresponding connections on bulb 20 on the described tooth bar 5 and the shifting ring 6; Described shifting ring 6 is movably arranged on by central stay bearing plate 7 on the connecting element 8 of base 1, and described shifting ring 6 is the fulcrum that shifting ring 6 rotates with the point of connection of connecting element 8, described central stay bearing plate 7 be rotatably connected to shifting ring 6 on; Described shifting ring 6 is provided with dust protecting cap 19 with bottom 2.In addition, also be provided with on the described bottom 2 and be used for and base 1 bonded assembly assembling post 21 and lead outlet 22.
As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the difference of the utility model and prior art automobile rearview mirror deflector maximum is that bottom 2 of the present utility model is provided with one or two groove 9 with the corresponding section, bottom of tooth bar 5.
