Description

Rearview mirror assemblies

The present invention relates to a kind of rearview mirror assemblies, thereby thereby it comprise a mirror outer cover, one be contained in be used in the outer cover relative outer cover rotational angle mirror, be used for regulating mirror with respect to the direction location mirror of mirror outer cover so that provide the main regulation device of one first visual field and one to be used for causing the direction of mirror to change the location mirror so that the auxiliary conditioning unit of one second visual field to be provided.

Such rearview mirror assemblies obtains explanation in European patent A-0463563.The main regulation device comprises a pair of and mirror around pivotal joint and the actuation plunger that engages with driving cylinder on being installed in base, and auxiliary conditioning unit comprises the device that is used to change one of driving cylinder and the relative position of base.This relates to and uses specially designed main regulation device.

The another kind of rearview mirror assemblies of the above-mentioned type is announced in French Patent (FRP) A-2659051.At this, auxiliary conditioning unit is provided to change the direction of mirror outer cover in-to-in main regulation device.Thereby in fact auxiliary conditioning unit should change the position of the device of Duoing than independent mirror recuperation, so just increased danger, and promptly when the vehicle that this back mirror is housed is kept in motion, mirror will stand unacceptable vibration.

According to the present invention, in the rearview mirror assemblies of the above-mentioned type, the main regulation device is provided for changing the direction of attaching parts with respect to the mirror outer cover, auxiliary conditioning unit is provided for changing the direction of mirror with respect to attaching parts, the actuating device of auxiliary conditioning unit and attaching parts and mirror are installed separately, and described actuating device is connected with auxiliary conditioning unit by a soft drive wirerope.

In a kind of form of the present invention, the actuating device of auxiliary conditioning unit is contained in the mirror outer cover, selects as another kind, if there are not enough spaces in the mirror outer cover, this actuating device can be installed in the car body.In both cases, actuating device does not exert an influence to the weight and the mirror that axle mounting supports that drive of interconnecting piece, thereby can not increase the tendency of mirror vibration.

To with reference to accompanying drawing embodiments of the invention be discussed by example below:

Fig. 1 is the front view (being back view when being installed on the vehicle) of looking from observed ray according to the vehicle doorn mirror assembly of the first embodiment of the present invention, has removed mirror in the drawings, and has partly cut main regulating mechanism;

Fig. 2 is the planar view of mirror shown in Figure 1, cut-away housing parts;

Fig. 3 is the cutaway view of being done along Fig. 1 cutting line 3-3;

The local diagrammatic sketch of the part body that Fig. 4 is on the another location to be done, Fig. 3 is shown;

Fig. 5 to Fig. 8 be second embodiment with the corresponding figure of Fig. 1 to Fig. 4, the cutaway view of Fig. 7 is that the cutting line 7-7 along Fig. 5 does; And

Fig. 9 be mounted on the vehicle doorn according to the back mirror of third embodiment of the invention with the similar view of Fig. 1, partial cut-out mirror and main regulation mechanism.

Fig. 1 to Fig. 4 illustrates an external mirror having indicator light assembly, and this assembly comprises an outer cover 10 that is installed on the base 12, has on the base 12 it is fastened on double-screw bolt 14 on the automotive door.

Comprise a retainer 16 in the outer cover 10, the electronic main regulation of the double motor mechanism of a prior art is housed on it, the direction that is used to regulate attaching parts 20, the mirror holder 22 that looking glass 24 is housed is installed on the attaching parts 20.

As shown in Figure 3 and Figure 4, along the lower edge of attaching parts 20 pivot structure 26 is arranged, this pivot structure is meshed with complementary structure 28 on the mirror holder 22.For the rotation mirror holder of controlling around pivot structure 26 22 has one to comprise the back to flange 30 of a skewed slot 32.Slide block 34 is slidably mounted on the guide rail of stretching on the vertical edge above the attaching parts 20 36, and have an ingear pin 38 in the groove 20 on flange 30, slide block 34 along moving of guide rail 36 make mirror holder 22 from the inclined position that is parallel to attaching parts 20 shown in Figure 4 to downward-sloping position shown in Figure 3.As shown in Figure 3, when mirror holder was downward-sloping, mirror 24 was directed, thereby made the user can see corresponding automobile back wheel, so that can see the situation of trailing wheel near curb or other obstacles.

Slide block 36 links to each other with the core wire 40 of backguy 42.The other end of backguy 42 links to each other with the actuating device 44 that comprises an electrical motor 46.The back will be described in detail the operation of actuating device 44, at present, only it is also noted that electrical motor 46 actions, do straight-line motion to cause steel wire 40 with respect to the outer tube of backguy 42, thereby make mirror 24 motion between Fig. 3 and position shown in Figure 4 also just much of that.A compression spring 48 oppositely acts on the slide block 36 with backguy 42, to keep the tension force of core wire 40.

Multicable 50 stretches out from the base 12 of mirror assembly, and has a joint 52 that is used to connect the electrical wiring system of vehicle.This joint is connected on the electrical wiring system, so that provide power to the various electric operation parts in mirror outer cover 10.

Fig. 5 to Fig. 8 illustrates an alternative embodiment of the invention with illustrating, and the most of parts identical with the corresponding component of Fig. 1 to Fig. 4 mark with same parts number, will not describe in detail at this.But the electric operation mechanism 18 that is used to regulate the mirror direction will be substituted by electric operation mechanism 60.There are 3

backguys

62,64 and 66 that link to each other with lever operated controller 68 shown in Figure 5 in mechanism 60.

Fig. 9 illustrates another embodiment of the present invention with illustrating, and in ratio, base is installed on the door 72.The mirror outer cover 10 of Fig. 1 to Fig. 8 is replaced by mirror outer cover 70, and outer cover 70 does not have enough spaces to hold actuating device 44, so this routine actuating device 44 is contained in the door 72.The wirerope 74 that backguy among Fig. 1 to Fig. 8 is more grown replaces, and this wirerope has its center steel wire 76, and an end of steel wire 76 is connected on the slide block 34, and its other end is connected on the nut 78 on the actuating device 82 in-to-in screw rods 80.Screw rod 80 has a bigger miniature gears 84, and this miniature gears is arranged to be driven by the less miniature gears on the output shaft that is installed in electrical motor 88 86.

In inside, the actuating device 44 of Fig. 1 to Fig. 8 is identical with the actuating device of Fig. 9.
