And the two limiting elements 122 realize positioning with the supporting frame 121 through the inserting match between the first positioning holes 124 and the second positioning pins 125 respectively, thereby effectively increasing the positioning precision and mounting reliability between the primary optical element 11 and the first support 12.
Further, to facilitate assembling and prevent over-positioning, preferably, the first positioning hole 124 on one of the two limiting elements 122 is a circular hole, and the first positioning hole 124 on the other limiting element 122 is a waist-shaped hole.

In the present embodiment, in order to match with the case that the two limiting elements 122 are respectively arranged on the left and right sides of the primary optical element 21 in the primary optical element assembly 1, two slots 221 are respectively arranged on the left and right sides of the second support 22. An assembling space is formed between the two slots 221 for the insertion of the primary optical element assembly 1. After the two limiting elements 122 are assembled into the corresponding limiting slots 123 on the supporting frame 121, the two limiting elements and the supporting frame 121 constitute an entirety and are inserted into the corresponding slots 221, thereby realizing the assembling of the first support 12 and the second support 22.

Therefore, the first support 12 can insert into the slots 221 from the rear end of the slots 221 and forward into the slots 221 along the direction shown by the arrow in
To ensure that the contact match between the positioning surfaces of the first support 12 and the inner side surfaces of the slots 221 can effectively define the relative position of the first support 12 and the second support 22, preferably, the inner side surfaces of the slots 221 include front surfaces 221a, upper surfaces 221b and lower surfaces 221c, and the positioning surfaces of the first support 12 include front positioning surfaces located on the front end face of the first support 12, upper positioning surfaces located on the upper surface of the first support 12 and a lower positioning surface on the lower surface of the first support 12.

In the present embodiment, the front end faces 121a of the supporting frame 121 located directly in front of the limiting slots 123 constitute the front positioning surfaces of the first support 12. After the limiting elements 122 are assembled into the limiting slots 123 on the supporting frame 121, the upper surfaces 122b of the limiting elements 122 are higher than that of the supporting frame 121, so that the upper surfaces 122b of the limiting elements 122 constitute the upper positioning surfaces of the first support 12. The lower surface 121b of the supporting frame 121 constitutes the lower positioning surface of the first support 12. Please refer to
Further, in the present embodiment, preferably, the slots 221 penetrate through the second support 22 in the left-right direction, and the left and right sides of the first support 12 are respectively provided with a clamping part 126. The opposite inner side surfaces 126a of the two clamping parts 126 are respectively in contact with the left side surface 22b and the right side surface 22c of the second support 22, to limit the left-right movement of the first support 12 relative to the second support 22. In a preferred embodiment, the two clamping parts 126 are respectively arranged on the left and right side surfaces of the supporting frame 121 and both extend forwards to the front of the front end face 121a of the supporting frame 121.

In summary, as to the vehicle lamp optical element assembly of the present embodiment, the primary optical element 11 and the secondary optical element 21 are assembled into an integral structure through matched connection of the first support 12 and the second support 22, thereby realizing direct determination of the relative position and direct positioning of the primary optical element 11 and the secondary optical element 21. Moreover, the forward movement of the first support 12 relative to the second support 22 is limited through contact between the front positioning surfaces of the first support 12 (front end faces 121a of the supporting frame 121) and the front surfaces 221a on the inner side of the slots 221 of the second support 22. The upward movement of the first support 12 relative to the second support 22 is limited through the contact between the upper positioning surfaces of the first support 12 (upper surfaces 122b of the limiting elements 122) and the upper surfaces 221b on the inner side of the slots 221. The downward movement of the first support 12 relative to the second support 22 is limited through the contact between the lower positioning surface of the first support 12 (lower surface 121b of the supporting frame 121) and the lower surfaces 221c of the inner side of the slots 221. The left and right movement of the first support 12 relative to the second support 22 is limited through the contact between the two opposite inner side surfaces 126a of the two clamping parts 126 of the first support 12 and the left side surface 22b and the right side surface 22c of the second support 22, respectively. And the backward movement of the first support 12 relative to the second support 22 is limited through the contact match between the rear positioning surface of the first support 22 (the rear end face 121c of the supporting frame 121) and the surface 3a of the circuit board 3 and through the connected match between the protruding parts 223 at the rear end of the second support 22 and the surface 3a of the circuit board 3. Consequently, relative fixation of the first support 12 and the second support 22 along the front-back, up-down and left-right directions are realized, and all-round positioning precision and mounting stability of the first support 12 and the second support 22 are ensured, that is, the positioning precision and mounting stability of the primary optical element 11 and the secondary optical element 21 are ensured. After the vehicle lamp optical element assembly is used for a long time, the relative position between the primary optical element 11 and the secondary optical element 21 can still be maintained unchanged, so as to ensure the accuracy and stability of the light shape of the vehicle lamp. In addition, after assembling the primary optical element assembly 1 and secondary optical element assembly 2 into an integral structure and determining the relative positions of the primary optical element 11 and the secondary optical element 21, the integral structure can be mounted on the circuit board 3 and the radiator 4 which can reduce the positioning precision requirements of the circuit board 3 and the radiator 4 and make the mounting process easier and more convenient.
