This design not only ensures the overall rigidity of the support frame and the frame body, but also reduces the vibration transmission. BRIEF DESCRIPTION OF THE DRAWINGS

The second rotating part 21 is rotatably connected to the first rotating part 11, so that the projector body 2 can rotate relative to the first rotating part 11, thereby adapting to changes in projection position and angle, thereby ensuring picture clarity.

[0041] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, it also includes a first connecting member 5 and a second connecting member 6, the end of the second transmission rod 32 connected to the first transmission rod 31 is provided with a first rotating hole 321, the first connecting member 5 is connected to the first transmission rod 31 through the first rotating hole 321, the end of the second transmission rod 32 connected to the projector body 2 is provided with a second rotating hole 322, and the second connecting member 6 is connected to the projector body 2 through the second rotating hole 322.

[0044] like Figure 1-Figure 4As shown, on the basis of the above embodiment, one end of the first connecting member 5 is provided with a first anti-detachment member 51, the second connecting member 6 is provided with a second anti-detachment member 61, one end of the second transmission rod 32 is located between the first transmission rod 31 and the first anti-detachment member 51, and the other end of the second transmission rod 32 is located between the projector body 2 and the second anti-detachment member 61.

[0046] Specifically, the second anti-slipping member 61 may be a nut, the second connecting member 6 may be a screw, and the second anti-slipping member 61 is threadedly connected to the second connecting member 6 .

[0047] In this embodiment, the first anti-detachment member 51 contacts the two transmission rods to prevent the first transmission rod 31 and the second transmission rod 32 from detaching during the mutual rotation movement of the first transmission rod 31 and the second transmission rod 32, and the second anti-detachment member 61 contacts the second transmission rod 32 to prevent the projector body 2 and the second transmission rod 32 from detaching during the mutual rotation movement of the second transmission rod 32 and the projector body 2.

[0048] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, the driving assembly 4 includes a motor 41, a lead screw 42 and a linkage block 43, the motor 41 is connected to the support frame 1, the lead screw 42 is connected to the output shaft of the motor 41, the linkage block 43 is provided with an internal thread, the linkage block 43 is threadedly connected to the lead screw 42, and the first transmission rod 31 is connected to the linkage block 43.

[0049] Specifically, the linkage block 43 is configured as a lead screw seat, and the motor 41 drives the lead screw 42 to perform rotational motion relative to the linkage block 43 .

[0050] In this embodiment, the motor 41 drives the lead screw 42 to rotate relative to the linkage block 43 . Since the linkage block 43 is connected to the first transmission rod 31 , the rotation of the linkage block 43 is restricted, thereby enabling the linkage block 43 to move along the lead screw 42 .

[0051] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, it also includes a fastener 7, the linkage block 43 is also provided with a first connecting hole 431, the first transmission rod 31 is provided with a second connecting hole 311, the fastener 7 passes through the second connecting hole 311 and is connected to the first connecting hole 431, thereby connecting the first transmission rod 31 with the linkage block 43.

[0052] In this embodiment, after the fastener 7 passes through the second connection hole 311 and enters the first connection hole 431 , the first transmission rod 31 and the linkage block 43 are fixed together by tightening or other locking mechanisms.

[0053] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, the number of the first connecting holes 431 is at least two, the number of the second connecting holes 311 is the same as the number of the first connecting holes 431, the number of the fasteners 7 is the same as the number of the first connecting holes 431, and each of the fasteners 7 passes through each of the second connecting holes 311 and is connected to each of the first connecting holes 431, thereby limiting the rotation of the first transmission rod 31 relative to the linkage block 43.

[0054] In this embodiment, each of the fasteners 7 passes through each of the second connecting holes 311 and is connected to each of the first connecting holes 431. Since the number of the first connecting holes 431, the second connecting holes 311 and the fasteners 7 is the same and is at least two, the position of the rotation center of the first transmission rod 31 can be fixed, thereby limiting its rotation relative to the linkage block 43.

[0055] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, the support frame 1 is provided with at least two positioning holes 12, and the motor 41 is provided with positioning members 411 whose number is the same as the number of the positioning holes 12, and the positioning members 411 are connected to the positioning holes 12, thereby limiting the rotation of the motor 41 relative to the support frame 1.

[0056] In this embodiment, the positioning member 411 is connected to the positioning hole 12, and the number of the positioning holes 12 and the positioning member 411 is the same and at least two, thereby limiting the rotation of the motor 41 relative to the support frame 1, and thereby enabling the screw driven by the output shaft of the motor 41 to rotate relative to the support frame 1.

[0057] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, the support frame 1 is further provided with a mounting hole 13, and the mounting hole 13 is used to be connected to the frame body.

[0058] Specifically, the mounting hole 13 is in the shape of an elongated strip.

[0059] In this embodiment, a mounting hole 13 is provided on the support frame 1. The design of the mounting hole 13 reserves adjustment room for the connection between the support frame 1 and the frame body, allowing the position of the support frame 1 to be fine-tuned within a certain range.

[0060] like Figure 1-Figure 4 As shown, based on the above embodiment, the support frame 1 is bent to form a mounting portion 14 , and the mounting hole 13 is located at the mounting portion 14 .

[0061] In this embodiment, the support frame 1 is bent to form a mounting portion 14, which ensures that the support frame 1 can maintain the necessary strength while being able to adapt to the structure of the frame body, and can more conveniently install the support frame 1 to the frame body without being affected by obstruction of other components.

[0062] like Figure 1-Figure 4 As shown, on the basis of the above embodiment, the mounting portion 14 is protruded to form a shock absorbing protrusion 141, the mounting hole 13 is arranged on the shock absorbing protrusion 141, and the shock absorbing protrusion 141 is used to contact the frame body.

[0063] Specifically, after the support frame 1 is installed with the frame body through the installation hole 13 , the shock-absorbing protrusion 141 contacts with the frame body.

[0064] In this embodiment, after the shock-absorbing protrusion 141 is installed in contact with the frame body, a circle of buffer zone (not shown in the figure) is formed around the shock-absorbing protrusion 141. When the vehicle is traveling on a bumpy road, the vibration generated by the frame body will be preferentially transmitted to the buffer zone through the shock-absorbing protrusion 141. After passing through the buffer zone, the vibration transmitted to the projector body 2 has been reduced a lot accordingly. Such a design not only ensures the overall rigidity of the support frame 1 and the frame body, but also reduces the vibration transmission.
