Description

Vehicle rearview mirror

The present invention relates to a rearview mirror, and in particular to a rearview mirror assembled on a vehicle handle.

Two-wheeled vehicles such as bicycles and motorcycles are very popular means of transportation for modern people. These vehicles are equipped with a rearview mirror on each side of the handlebars so that the driver can use the rearview mirror to view the rear situation when driving on the road, especially when changing lanes or turning, thereby improving driving safety and reducing the incidence of accidents.

Since vehicles may occasionally change drivers, the rearview mirrors often have to adjust their angles according to the height and habits of the drivers, or even if the drivers have not changed, the angles may change due to changes in the viewing angles required. To solve this problem, many innovative rearview mirror structures have been proposed, such as the bicycle rearview mirror of No. M485844, the vehicle rearview mirror folding structure of No. M556222, and the bicycle combined rearview mirror structure of No. M640615. The rearview mirror structures of these patents are all designed on the extension column of the mirror seat, and a spherical universal joint is provided at the end of the extension column. Through this universal joint, the rearview mirror can freely adjust the viewing angle according to the needs of the driver.

However, these conventional vehicle rearview mirror structures still have some problems. Since the extension column and the universal joint are integrally molded with the mirror base, the difficulty of injection molding is relatively high, and the manufacturing cost is also increased. In addition, since the mirror base is generally made of plastic material, the extension column and the universal joint are also made of plastic material, resulting in poor structural strength and easy to break during use. This situation leads to poor durability of the rearview mirror and a short service life.

The inventor of the present invention has come up with the idea of creating a vehicle rearview mirror in view of the above-mentioned shortcomings of the known vehicle rearview mirror structure. After much discussion and trial production of samples, as well as many revisions and improvements, the present invention is launched.

The present invention discloses a vehicle rearview mirror, comprising: a bracket, one end of which is provided with a fixing portion, and the other end of which is provided with an arc groove and an internal threaded portion connected thereto; a pivot piece, one end of which is provided with a sleeve portion, and the other end of which is provided with a spherical universal joint, the universal joint being sleeved on the arc groove, the sleeve portion passing through the outer side of the arc groove, the sleeve portion being provided with a sleeve hole toward the universal joint, the universal joint being provided with a fixing hole toward the sleeve portion, the fixing hole being communicated with the sleeve hole; a mirror body; , a mirror surface is provided on the front side, a fitting column is provided on the back side, a screw hole is provided in the fitting column, and the fitting column is fitted with the fitting hole of the pivot piece; a locking screw is passed through the fixing hole of the pivot piece and is screwed and fixed with the screw hole of the mirror body; and a cover is provided with a pressing part at one end, and an external threaded part is provided on the outer peripheral surface, and the external threaded part is screwed with the internal threaded part of the bracket, so that the universal joint of the pivot piece can be pivotally sandwiched between the arc groove of the bracket and the pressing part of the cover.

The main purpose of the vehicle rearview mirror of the present invention is that its hinge is an independent component, which is locked to the mirror body by a locking screw. The difficulty of injection molding is relatively low, and the manufacturing cost is also reduced. In addition, the structural strength of the hinge can be improved to avoid the hinge from breaking during use, and the durability is good and the service life is long.

The following is a further description of the preferred embodiments of the present invention in conjunction with the drawings, so that those familiar with the relevant technology of the present invention can implement it according to the description of this specification.

First, please refer to the first to fourth figures, the vehicle rearview mirror of the present invention includes: a bracket 10, a hinge 20, a mirror body 30, a locking screw 40 and a cover 50.

The bracket 10 has a fixing portion 11 at one end and an arc groove 12, an internal threaded portion 13 and an interlocking groove 14 at the other end. The internal threaded portion 13 is disposed between the arc groove 12 and the interlocking groove 14. In this embodiment, the bracket 10 is L-shaped and the fixing portion 11 is a plunger.

The hinge 20 is made of plastic material, with a hexagonal cone-shaped sleeve portion 21 at one end and a spherical universal joint 22 at the other end. The universal joint 22 is sleeved on the arc groove 12 of the bracket 10. The sleeve portion 21 passes through the outer side of the arc groove 12. The sleeve portion 21 is provided with a sleeve hole 211 toward the universal joint 22. The universal joint 22 is provided with a fixing hole 221 toward the sleeve portion 21. The fixing hole 221 is communicated with the sleeve hole 211.

The mirror body 30 has a mirror surface 31 on the front side and a hexagonal cone-shaped socket groove 32 on the eccentric side of the back side. A socket column 33 is provided in the socket groove 32. A screw hole 34 is provided in the socket column 33. The socket groove 32 is used for socketing and positioning the socket portion 21 of the hinge 20. The socket column 33 is socketed with the socket hole 211 of the hinge 20.

The locking screw 40 is made of metal, passes through the fixing hole 221 of the hinge 20 , and is screwed and fixed with the screw hole 34 of the lens body 30 .

The cover 50 has a pressing portion 51 at one end and an enlarged end portion 52 at the other end. The outer circumference of the cover 50 has an external threaded portion 53. The outer circumference of the cover 50 has an engaging portion 54 near the end portion 52. The external threaded portion 53 is screwed with the internal threaded portion 13 of the bracket 10, so that the universal joint 22 of the pivot 20 can be pivotally clamped on the bracket 10. Between the arc groove 12 and the pressing portion 51 of the cover 50, the engaging portion 54 of the cover 50 is embedded in the engaging groove 14 of the bracket 10, and the end portion 52 covers the outer side of the engaging groove 14 of the bracket 10. A rotatable operating portion 521 is provided on the end portion 52. In this embodiment, the pressing portion 51 is a spherical groove, and the operating portion 521 is a hexagonal groove.

When the vehicle rearview mirror of the present invention is assembled on a vehicle (such as a bicycle or motorcycle), the fixing portion 11 of the bracket 10 is inserted into the vehicle handle and fixed, so that the mirror body 30 is located outside the vehicle handle. The mirror body 30 can be used to clearly reflect the rear situation without being blocked by the driver himself, so that the driver can directly or with the corner of his eye observe the mirror surface 31 of the mirror body 30, thereby improving driving safety and reducing the incidence of accidents. When the viewing angle of the mirror surface 31 is not good, since the mirror body 30 is pivotally clamped between the arc groove 12 of the bracket 10 and the pressing portion 51 of the cover 50 by the universal joint 22 of the hinge 20, the mirror body 30 can be universally rotated with the universal joint 22 of the hinge 20 as the axis to adjust the elevation angle or rotation angle of the mirror body 30, so that the mirror surface 31 forms the best viewing angle, avoids the visual blind spot, and further improves driving safety.

The structure of the above specific embodiment can obtain the following benefits:

1. In the vehicle rearview mirror of the present invention, the hinge 20 is an independent component and is molded separately from the mirror body 30. Therefore, the difficulty of injection molding the hinge 20 is low, and the manufacturing cost is also reduced accordingly.

2. The vehicle rearview mirror of the present invention has a hinge 20 that is locked to the mirror body 30 by a locking screw 40, thereby improving the structural strength of the hinge 20 and preventing the hinge 20 from breaking during use, thereby improving durability and extending service life.
