Abstract

A vehicular side view minor includes a minor seat having an engagement portion. A light-impermeable first annular wall protrudes rearwards from an inner periphery of a through-hole in the engagement portion. A minor is mounted in front of the minor seat and includes a reflective layer. A light-permeable housing is mounted to the engagement portion and has a second annular wall extending through the first annular wall. A front wall of the second annular wall includes an optical lens portion. A circuit board is received in the housing and has a lighting element. The circuit board includes a periphery abutting an abutment portion of the second annular wall. A gluing material is filled in a gluing space behind the circuit board and sealingly covers a rear surface of the circuit board, front sections of two wires, and a portion of the second annular wall to form a sealing portion.

Claims

1. A vehicular side view minor comprising:

a mirror seat including a front side and a rear side, with an engagement portion mounted on the rear side and including a through-hole having an inner periphery, with a first annular wall protruding rearwards from the inner periphery of the through-hole, and with the first annular wall not permeable to light;

a minor mounted in front of the minor seat, with the minor including a front face and a rear face, and with the rear face of the minor including a reflective layer;

an illumination device including a housing and a circuit board, with the housing permeable to light and including a second annular wall extending through the first annular wall, with the second annular wall including a front wall at a front end thereof, with the second annular wall further including a rear end having an opening, with the second annular wall further including an intermediate portion having a compartment, with the second annular wall further including an abutment portion on an inner face of the intermediate portion thereof, with the front wall including an optical lens portion protruding from an inner face of the front wall, with the housing mounted to the engagement portion of the minor seat, with the front wall facing the rear face of the minor, with the circuit board including a front surface and a rear surface, with the circuit board further including at least one lighting element and two wires, with the at least one lighting element mounted on the front surface of the circuit board, and with an emitting direction of the at least one lighting element being towards the optical lens portion of the housing, with the circuit board received in the compartment of the housing, with the circuit board including a periphery abutting the abutment portion, with the second annular wall further including a gluing space located behind the rear surface of the circuit board, with a gluing material filled in the gluing space and sealingly covering the rear surface of the circuit board, front sections of the two wires, and a portion of the second annular wall of the housing to form a sealing portion; and

a rear cover mounted behind the mirror seat and enclosing the illumination device.

2. The vehicular side view mirror as claimed in claim 1, wherein the abutment portion of the housing is an annular stepped portion, and wherein the front surface of the circuit board abuts the annular stepped portion.

3. The vehicular side view mirror as claimed in claim 1, with the first annular wall of the mirror seat including a coupling groove, with the second annular wall of the housing including a coupling member, and with the coupling member assembled in the coupling groove.

4. The vehicular side view mirror as claimed in claim 1, wherein the rear face of the mirror has a portion aligned with the engagement portion of the mirror seat, and wherein the portion of the rear face is a light-permeable section not covered by the reflective layer.

5. The vehicular side view mirror as claimed in claim 1, wherein the inner face of the front wall of the housing and the rear face of the mirror are glued together by a gluing element.

6. The vehicular side view mirror as claimed in claim 1, with the rear face of the minor having a portion aligned with the engagement portion of the minor seat, with the portion of the rear face being a light-permeable section not covered by the reflective layer, with the inner face of the front wall of the housing and the rear face of the minor glued together by a gluing element, with the gluing element being a double-sided tape including a hollow portion aligned with the optical lens portion.

7. The vehicular side view mirror as claimed in claim 2, with the circuit board received in the compartment of the housing, with the periphery of the circuit board abutting the annular stepped portion, wherein the gluing material in a liquid state is filled into the gluing space, and wherein the sealing portion is formed after the gluing material cures and engages with the rear surface of the circuit board, the front sections of the two wires, and the portion of the second annular wall of the housing.

8. The vehicular side view mirror as claimed in claim 5, wherein the gluing element is a double-sided tape including a hollow portion aligned with the optical lens portion.
