Description

A kind of mounting structure of the electric foldable device of automobile outer rear-view mirror

Technical field

The utility model relates to automobile outer rear-view mirror technical field, in particular to a kind of electric foldable of automobile outer rear-view mirror The mounting structure of device.

Background technique

Automobile outer rear-view mirror is the automobile for observing front vehicle, pedestrian's operating status during running automobile for driver Accessory is the necessary guarantee of safe driving, by the adjustment to outside rear-view mirror setting angle, driver can be made to observe certain party Safe driving is convenient in the visual field of position.Therefore, the importance of outside rear-view mirror is known by everybody.And since outside rear-view mirror is installation In two side position of automobile, the outside rear-view mirror of automobile external is mounted on commonly using electrically-driven device, to avoid running car In relatively narrow spatial position or pedestrian, outside rear-view mirror collides with other vehicles, pedestrian and vehicle is caused to damage when more complicated occasion Bad or unnecessary dispute.

The electric folding device includes shell, is located at pin shaft of the casing center for connecting with housing into rotation, is located at shell The interior electric drive unit rotated for drive shell relative to pin shaft, the lower end of pin shaft and mounting rack circumferentially limit, and housing bottom is also Equipped with the pedestal connecting with housing into rotation, pedestal is threadably secured with mirror support, this kind of structure has the following deficiencies: that pin shaft is set In the base in the through-hole of the heart, the diameter of pin shaft is limited by pedestal can not do thick, elongated pin shaft lower end and mounting rack circumferentially limit When position, the stability after pin shaft insertion is inadequate, and pin shaft occurs axial float easily with respect to mounting rack and leads to the assembly of mirror substrate not Surely；It is again to consolidate pedestal and mirror support screw thread after axially being plugged together by pin shaft with mounting rack that electric folding device is connect with mirror support Fixed, pin shaft and pedestal are two parts without matching relationship, and the two cooperates with mirror support on mounting rack respectively, can not make jointly With support force is provided, cause electric folding device assembly rear stability poor, electric folding device entirety anti-jitter ability is poor；Pass through Screw thread connects pedestal with mirror support with by electric folding device axial limiting, on mirror support, when for a long time, use or vehicle are trembled Dynamic when leading to thread looseness, electric folding device is easy to happen axial float.

Summary of the invention

High, whole anti-jitter ability that the technical problem to be solved by the utility model is to provide a kind of assembly rear stabilities A kind of mounting structure of the electric foldable device of good automobile outer rear-view mirror.

A kind of the technical scheme in the invention for solving the above technical problem are as follows: electric foldable device of automobile outer rear-view mirror Mounting structure, including be fixedly installed on mirror substrate shell, be fixed on the pedestal of housing bottom, the base bottom is equipped with Pedestal for being rotatablely connected with pedestal, the pedestal lower end are additionally provided with connector, and the connector and pedestal lower end periphery are matched Close the position limiting structure being equipped with for circumferentially limiting mounting rack and pedestal and with shell axial limiting.

Compared with the prior art, the advantages of the utility model are: position limiting structure is located at pedestal lower end periphery, therefore limit knot The diameter and base diameter of structure are adapted, and the diameter of position limiting structure is bigger compared to the diameter of former pin shaft, electric folding device dress It is good with rear stability；Position limiting structure collective effect with both pedestal lower end periphery and connector lower end, to electric foldable Installation of the device on mirror support provides limit, so that electric folding device anti-jitter ability is strong, after electric folding device assembly Stability is more preferable.

As a kind of improvement of the utility model, the position limiting structure includes for by pedestal lower end periphery and mounting rack Hold the first position limiting structure circumferentially limited, for mounting rack to be pressed together on pedestal and circumferentially limit connector and pedestal Two position limiting structures, for passing through the improvement, three position limiting structures for the third position limiting structure of connector and shell axial limiting Cooperation, installation is erected between pedestal and connector, and pedestal and mounting rack circumferentially limit, connector and pedestal axial limiting and Mounting rack is pressed together on pedestal, and connector and shell axial limiting, the axial limit by pedestal and connector of mounting rack, The circumferential limit by pedestal, mounting rack integrally limits stabilization, whole to pacify when so that electric folding device being mounted on mirror support Dress is stablized, and anti-jitter ability is good.

As the utility model there are also a kind of improvement, first position-limit mechanism includes being located at pedestal lower end periphery along axis To protrusion multiple ratchets, be located at the spine slot for cooperating with ratchet of mounting rack upper end edge axial direction indent, by the improvement, Multiple ratchets and spine slot cooperate so that pedestal and mounting rack circumferentially limit, and circumferential good limit effect, ratchet is circumferentially distributed, stability It is good.

As the utility model there are also a kind of improvement, second position-limit mechanism includes being located at connector bottom circumferentially Protrusion is used to offset with mounting rack lower end surface mounting rack to be pressed together on to multiple briquettings on pedestal, and the connector is circumferentially Protrusion is equipped with multiple limited blocks, is concaved in pedestal lower end week for cooperating with limited block with connector and pedestal is all To the limiting slot of limit, by the improvement, mounting rack is pressed together on pedestal by briquetting, i.e., carries out axis after being inserted into spine slot to ratchet To limit, and pedestal and connector pass through the limited block being circumferentially arranged and limiting slot cooperation limits, circumferential good limit effect, limit Block is circumferentially distributed, and stability is good.

As a kind of also improvement of the utility model, the third position limiting structure includes the rotation axle portion for being located at connector Multiple convex blocks of upper and circumferentially spaced protrusion are located at enclosure interior for cooperating with convex block with the limit to connector axial limiting Position ring, by the improvement, connector by the convex block of rotation axle portion with can the cooperation of intracorporal stop collar carry out axial limiting, and Connector still can be with respect to housing into rotation, to meet the structure needs that shell can be rotated relative to mirror support.

As the utility model there are also a kind of improvement, the stop collar is up-narrow and down-wide truncated cone-shaped sheet body, described The internal diameter of body is greater than the outer diameter of connector rotation axle portion and is less than the diameter of a circle that multiple convex block outer walls are constituted, and is changed by described Into connector assembles upwards, the up-narrow and down-wide setting of stop collar, and convex block is squeezed upward into stop collar and is easy, by truncated cone-shaped piece after squeezing into The influence of body structure, boss deviate from downwards that stop collar is relatively difficult, and overall structure is simple, and the cooperation of convex block and stop collar efficiently may be used It leans on.
