Universal type mounting structure for car lamp bulb and method for assembling universal type mounting structure for car lamp bulb with bulb

A universal type mounting structure for a car lamp bulb is used for mounting the car lamp bulb by being cooperated with a bulb base, which comprises a first contact piece (1), a reflecting mirror mounting part (2) and a supporting seat (3), wherein the supporting seat (3) is arranged in the reflecting mirror mounting part (2);

• the universal type mounting structure for a car lamp bulb is characterized in that
• the first contact piece (1), which is cooperated with the supporting seat (3), comprises a clamping foot (4), a semi-circular pressing sheet (5) and a row of pressing sheet (6);
• the row of pressing sheet (6) is arranged on the first contact piece (1) in manner of extending towards the two sides by taking a position opposite to the clamping foot (4) as a datum point;
• the reflecting mirror mounting part (2) comprises a first cylindrical hole (7), a first supporting plane (8), a second cylindrical hole (9), a second supporting plane (10), three fan-shaped lug bosses, a lug boss (12), a pair of guide surfaces (13) and two V-shaped locating surfaces (14);
• wherein
• the first supporting plane (8) is arranged between the first cylindrical hole (7) and the second cylindrical hole (9) and extends from a radial periphery outside the first cylindrical hole (7) to an inner diameter of the second cylindrical hole (9);
• the second supporting plane (10) is arranged in manner of extending from the radial periphery outside the second cylindrical hole (9);
• the three fan-shaped lug bosses comprising a fan-shaped lug boss 1 (11-1), a fan-shaped lug boss 2 (11-2) and a fan-shaped lug boss 3 (11-3) respectively are distributed on the first supporting plane (8) and an inner wall of the second cylindrical hole (9), and an area formed by the three fan-shaped lug bosses is in the shape of a waist-shaped slot;
• the first contact piece (1) is arranged on the second supporting plane (10);
• the supporting seat (3) is arranged in the waist-shaped slot formed by the three fan-shaped lug bosses, a square lug boss (12) is arranged on the supporting seat (3), and the square lug boss (12) is located just below the clamping foot (4) in an axial direction, so that the supporting seat (3) cannot drop out of the reflecting mirror mounting part (2);
• the pair of guide surfaces (13) which are axially arranged are symmetrically arranged on the wall of the second cylindrical hole (9), and the two V-shaped locating surfaces (14) at an angle of 90 degrees are arranged on the wall of the second cylindrical hole (9) along the axial direction.
