Ring elastic parts 14 are equipped with, ring elastic parts 14 are sheathed on the outer arc spherical surface of lug boss 11 and support with the inner arc spherical surface of groove 31
It connects.Specifically, by adding ring elastic parts 14 between the outer arc spherical surface of lug boss 11 and the inner arc spherical surface of groove 31, in this way
It just will not directly contact between the outer arc spherical surface of lug boss 11 and the inner arc spherical surface of groove 31, but connect with ring elastic parts 14
It touches and then also achieves effective buffering during pivoting friction, so just avoid the outer arc spherical surface and groove of lug boss 11
31 inner arc spherical surface rigid contact and the abrasion occurred.
Further, ring elastic parts 14 are falope ring.So have benefited from the good elasticity of silica gel and wearability, annular elastomeric
Property part 14 just can also ensure that it possesses enough service life while maintaining enough resilient supports.
In the present embodiment, as shown in figure 3, mirror holder 30 offers assembly cavity 32, eyeglass 40 away from the side of lug boss 11
It is embedded in assembly cavity 32.Meanwhile the bottom of assembly cavity 32 is also provided with annular loss of weight chamber 33, annular loss of weight chamber 33, which encloses, to be set to be formed
There is mounting portion 34, groove 31 is opened in mounting portion 34 towards the side of lug boss 11.Specifically, by being offered on mirror holder 30
Assembly cavity 32 provides the region for stablizing installation just in this way for eyeglass 40, and is subtracted by opening up annular in the bottom of assembly cavity 32
Weight chamber 33 just significantly reduces the overall weight of mirror holder 30 in this way, thereby reduces the load burden of connecting rod 21.
In the present embodiment, as shown in Figure 3 and Figure 4, backsight blind angle auxiliary mirror provided by the embodiment of the utility model also wraps
Buffering spacer 35 is included, buffering spacer 35 is set between eyeglass 40 and the bottom of assembly cavity 32.Specifically, by eyeglass 40 and dress
Buffering spacer 35 is added between bottom with chamber 32, such buffering spacer 35, which is just filled between eyeglass 40 and assembly cavity 32, to be existed
Some fit-up gaps enable eyeglass 40 to be embedded in assembly cavity 32 more stablely, avoid eyeglass 40 in external force
The phenomenon that deviating from assembly cavity 32 by shake down occurs.
In the present embodiment, buffering spacer 35 is EVA (ethylene-vinyl acetate copolymer) gasket.So by that will buffer
Gasket 35 is set as EVA gasket, then having benefited from that EVA material flexibility is good, the good feature of impact resistant strength is set to 40 He of eyeglass
EVA gasket between 32 bottom of assembly cavity just can be filled in the gap between 32 bottom of eyeglass 40 and assembly cavity, and then be made
The chimeric compactness for obtaining 32 bottom of eyeglass 40 and assembly cavity is obviously improved.
In the present embodiment, as shown in Figures 1 to 3, backsight blind angle auxiliary mirror provided by the embodiment of the utility model further includes
Face ring part 50, face ring part 50 are installed on the outline border edge of mirror holder 30 and are covered in the outer edge of eyeglass 40.Specifically, by mirror
The outline border edge of frame 30 adds face ring part 50 again, and face ring is made just to like that you are covered in the outer edge of eyeglass 40, so on the one hand
Eyeglass 40 is further limited in the displacement freedom of assembly cavity 32, further improves installation of the eyeglass 40 in assembly cavity 32
Stability.On the other hand extraneous dust impurity is also prevented to enter by the gap between 32 inner wall of eyeglass 40 and assembly cavity
In assembly cavity 32, so ensure that backsight blind angle auxiliary mirror in complicated air environment (such as dust environment or wind sand environment),
Internal cleannes.
In the present embodiment, mirror holder 30, microscope base 10 and face ring part 50 are Al-alloy parts.Specifically, by by mirror holder 30,
Microscope base 10 and face ring part 50 are set as Al-alloy parts, firstly, having benefited from the good mechanical property of aluminium alloy, mirror holder 30, microscope base
10 and face ring part 50 be just hardly damaged in the long-term use.On the other hand, since aluminium alloy is more slim and graceful compared with other metals,
Also ensure that backsight blind angle auxiliary mirror under the premise of possessing better integral strength, also ensures its own weight in this way
It does not significantly rise.
In the present embodiment, shown in as shown in Figure 1, Figure 3 and Figure 4, microscope base 10 is sticked away from the side of lug boss 11 adhesive sheet
15.Specifically, adhesive sheet 15 can be 3M double coated film.In this way, film is set by gluing on microscope base 10, such backsight blind angle auxiliary
Mirror, which can steadily glue, to be set on rearview mirror.And by the way that adhesive sheet 15 is set as 3M double coated film, then having benefited from 3M film
Bonding reliability, microscope base 10 just can be bonded on rearview mirror relatively stablely.
In the present embodiment, connecting rod 21 is attachment screw, and the bottom of groove 31 offers threaded hole (not shown), even
Screw is connect across elastic component 22 and is adapted to connection with threaded hole.Specifically, by the way that connecting rod 21 is set as attachment screw, this
Sample has just been obviously improved the detachability energy of backsight blind angle auxiliary mirror.As, when need by microscope base 10 and mirror holder 30 combination assembly
When, attachment screw can be sent into inner cavity 12 and pass through elastic component 22 and through hole 13 and be inserted in what 31 bottom of groove was reserved
In threaded hole.When needing to dismantle lower mirror holder 30, it is only necessary to attachment screw be screwed out threaded hole, just make backsight in this way
The integral disassembly, assembly of blind angle auxiliary mirror becomes convenient and quick.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
