Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1

[0034] Please refer to Figures 1-6 As shown, an adjustable metal casting for a car spoiler includes a main wing plate 1. Sliding grooves 10 are provided on both end faces of the main wing plate 1 along the length direction; auxiliary wing plates 2 are slidably installed at both sliding grooves 10. A plurality of fixing grooves 20 are provided on the bottoms of the two auxiliary wing plates 2 along the length direction; wing side plates 3 are fixed to the ends of the two auxiliary wing plates 2 away from each other; fixing parts 4 are fixed to both ends at the bottom of the main wing plate 1. The fixing part 4 includes two brackets 40 fixedly connected to both ends at the bottom of the main wing plate 1. Fixing seats 42 are fixed to the opposite side faces of the two brackets 40. A sliding cavity 420 is provided inside each fixing seat 42. A movable frame 45 is slidably installed at the top inside the sliding cavity 420. Two guide rods 43 are fixed to the bottom inside the sliding cavity 420. The top ends of the guide rods 43 penetrate through the bottom of the movable frame 45 and are slidably connected to the movable frame 45. A spring 44 for pressing against the movable frame 45 is sleeved on each guide rod 43 and located outside the bottom of the movable frame 45; a fixing plate 48 is fixed to the top of the movable frame 45. The top end of the fixing plate 48 sequentially slides through the top of the fixing seat 42 and the top of the bracket 40, and the top end of the fixing plate 48 can slide through the bottom of the main wing plate 1 and is inserted and matched with the corresponding fixing groove 20. Among them, one end of the spring 44 is connected to the bottom of the movable frame 45, and the other end is connected to the inner bottom wall of the sliding cavity 420.

[0035] In this embodiment, the cross-sectional shape of the movable frame 45 is in a square shape, and the size of the movable frame 45 is adapted to the size of the sliding cavity 420. The square shape design facilitates the installation and fixation of the movable frame 45 and the fixing plate 48, and the adapted size ensures the smoothness and stability of the lifting of the movable frame 45.

[0036] In this embodiment, a connection groove 421 communicating with the sliding cavity 420 is provided on the side face of the fixing seat 42 away from the bracket 40. An opening is provided on the side face of the movable frame 45 away from the bracket 40. A connecting plate 46 is fixed inside the movable frame 45. A slider 47 is slidably provided in the connection groove 421. One end of the slider 47 passes through the opening of the movable frame 45 and is fixedly connected to the top side face of the connecting plate 46. A dial groove 470 is provided on the other end face of the slider 47. The lifting of the movable frame 45 is facilitated through the dial groove 470, meeting the requirement for adjusting the auxiliary wing plate 2.

[0037] In this embodiment, a limit block 430 is coaxially fixed at the top end inside the movable frame 45 of the guide rod 43, and the diameter of the guide rod 43 is smaller than that of the limit block 430. The setting of the limit block 430 plays a role in limiting the movable frame 45, preventing the movable frame 45 from disengaging from the limit of the guide rod 43.

[0038] In this embodiment, mounting edges 402 are fixed on both sides of the top of the bracket 40. The two mounting edges 402 are symmetrically arranged, and fixing bolts 41 are inserted through both ends of each mounting edge 402, and the fixing bolts 41 are threadedly connected to the bottom of the main wing plate 1. This bolt - fixing method ensures the reliable installation of the bracket 40 and the main wing plate 1, and has the advantage of being easy to disassemble and assemble.

[0039] In this embodiment, two through - mounting grooves 401 are formed at the bottom of the bracket 40, and the cross - sectional shapes of the two mounting grooves 401 are rectangular. The setting of the mounting grooves 401 facilitates the insertion of bolts, and thus facilitates the fixation to the vehicle tail through bolts.

[0040] In this embodiment, the auxiliary wing plate 2 is perpendicular to the side wing plate 3, and the auxiliary wing plate 2 and the side wing plate 3 are fixedly connected by bolts. The bolt - fixing method ensures the reliable installation of the auxiliary wing plate 2 and the side wing plate 3, and ensures the use stability of the auxiliary wing plate 2 and the side wing plate 3.

[0041] When adjusting the auxiliary wing plate 2, the user first inserts a finger into the dial groove 470 and pushes downward. The slider 47 drives the connecting plate 46 and the movable frame 45 to move downward. The movable frame 45 drives the fixing plate 48 to move downward, so that the fixing plate 48 disengages from the fixing groove 20. At the same time, the spring 44 is compressed by the movable frame 45. At this time, the end of the fixing plate 48 disengages from the fixing groove 20, so that the restriction of the fixing plate 48 on the auxiliary wing plate 2 is released. Then the user pulls the auxiliary wing plate 2 to both sides, and the auxiliary wing plate 2 slides along the sliding groove 10. When the auxiliary wing plate 2 is adjusted to the appropriate position, the user releases the slider 47. Under the elastic action of the spring 44, the spring 44 pushes the movable frame 45 upward, and the movable frame 45 drives the fixing plate 48 to insert into the corresponding fixing groove 20. At this time, the auxiliary wing plate 2 is fixed. Repeat the above steps and adjust the auxiliary wing plate 2 on the other side.

[0042] Embodiment 2

[0043] Please refer to Figure 7 As shown, on the basis of Embodiment 1, this embodiment provides the following technical solution: A limit bolt 422 is threadedly connected to the outer wall of the side of the fixed seat 42 away from the bracket 40. The end of the limit bolt 422 threadedly penetrates and extends into the sliding cavity 420 and protrudes below the movable frame 45.

[0044] It should be added that since the end of the limit bolt 422 protrudes below the movable frame 45, when the vehicle causes the movable frame 45 to tend to move downward due to bumps or other reasons, the movable frame 45 is blocked by the limit bolt 422 and will not move up and down. Therefore, the fixed plate 48 fixed to the movable frame 45 remains stable. This design ensures the connection stability between the fixed plate 48 and the fixed groove 20, and further ensures the connection stability between the auxiliary wing plate 2 and the main wing plate 1.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
