The motor 310 is connected to the projector 200, with the gear 311 being connected to the rotating shaft 312 of the motor 310, and the toothed structure 112 being arranged on the support structure 100. The motor 310 rotates through the gear 311 along the toothed structure 112 to drive the projector 200 to rotate.

[0026] As in Fig. 2 and Fig. 3, the drive structure 300 may, for example, include a motor 310, a gear 311, and a toothed structure 112 meshing with the gear 311. In one possible embodiment, the motor 310 may be connected to the projector 200 as a power source to provide a driving force for rotating the projector 200. The gear 311 is connected to the rotating shaft 312 of the motor 310, and when the motor 310 is operating, the rotating shaft 312 of the motor 310 drives the gear 311 to rotate. The rotation of the projector 200 connected to the motor 310 along the toothed structure 112 is achieved by the toothed structure 112 meshing with the gear 311. It should be understood that the motor 310 is connected to the projector 200 when the motor 310 is operating.The motor 310 drives the gear 311 connected to the rotating shaft 312 to rotate, whereby the gear 311 rotates along the tooth structure 112 on the first bracket 110 to achieve rotation of the projector 200.

When the motor 310 drives the gear 311 to rotate along the tooth structure 112 on the first support 110 through the rotating shaft 312, the projector 200, which is fixedly connected to the motor 310, is driven to rotate.

[0029] With further reference to Fig. 1 and Fig. 2, the first bracket 110 may further be provided with a first opening 113. A connecting element 313 provided with a positioning hole is arranged at a position of the motor 310 corresponding to the first opening 113. A plurality of connecting portions 214 are arranged at a position of the projector 200 corresponding to the first opening 113, wherein the connecting element 313 of the motor 310 is connected to the connecting portions 214 of the projector 200 via a first fastening element 410. In one possible embodiment, the connecting portions 214 of the projector 200 may be provided in any number, and the present application does not limit the number of connecting portions 214 of the projector 200.In one example of the present application, the connecting portions 214 of the projector 200 are exemplified in three, with the first connecting portion 2141 passing through the first opening 113. The first opening 113 can achieve a positioning function to ensure that the gear 311 of the motor 310 engages with the tooth structure 112 of the first bracket 110 to realize that the projector 200 is driven to rotate. The first opening 113 can further reduce the weight of the bracket structure 100 to reduce the overall weight of the vehicle.

[0032] As in Fig. 2, the third connecting portion 2143 is located at a bottom of the second connecting portion 2142. It should be understood that the adjustment position of the connecting portion 214 must be adjusted to the position of the positioning hole of the connecting member 313 on the motor 310. It should be noted that the number of connecting portions 214 on the projector 200 and the number of positioning holes of the connecting member 313 on the motor 310 must also be consistent.

[0033] In some embodiments of the present application, as in Fig. As shown in Figure 3, a side of the first bracket 110 facing the motor 310 has an arcuate edge 111 on which the tooth structure 112 is formed. It should be noted that the arcuate edge 111 provided on the first bracket 110 contributes to reducing stress concentration, and the movement of the gear 311 of the motor 310 along the tooth structure 112 is smoother and more efficient at the arcuate edge 111.

[0034] It should be noted that, as in Fig. 2 and Fig. 3, the tooth structure 112 is provided on a part of the edge of the first bracket 110, but it is not limited to being provided only on a part of the edge of the first bracket 110, for example, the size of the tooth structure 112 on the edge of the first bracket 110 can also be expanded, and the size of the tooth structure 112 can be adjusted according to actual needs.

[0035] As in Fig. 2, a mounting portion 213 is further disposed on the projector 200, and the connecting portion 214 is connected to the mounting portion 213. The connecting portion 214 is connected to the connecting member 313 of the motor 310 via the mounting member. It should be understood that the mounting portion 213 is provided on the housing 210 of the projector 200 to increase the range of force exerted by the motor 310 on the rotation of the projector 200, improve the stability of the projector 200 during rotation, and reduce damage to the projector 200 due to uneven force.

[0036] With further reference to Fig. 1 and Fig. 2, a rotating shaft 212 is further arranged on the projector 200, which is connected to the support structure 100, wherein the projector 200 can rotate along the rotating shaft 212. The projector 200 is rotatably connected to the support structure 100 via the rotating shaft 212, wherein the rotating shaft 212 represents a stable center of rotation for the projector 200. When the motor 310 drives the gear 311 to move along the tooth structure 112 on the first support 110, the projector 200 can be driven to rotate along the rotating shaft 212, thereby realizing the need for the projector 200 to project at different angles. In one possible embodiment, symmetrical rotating columns are provided at both ends of the housing 210 of the projector 200, and the rotating shaft 212 is formed by two symmetrical rotating columns.The symmetrical pivot columns allow the projector 200 to be subjected to equal force on both sides during rotation to achieve smooth rotation.

[0037] It should be noted that in the embodiment of the present application, along the vertical direction of the rotary shaft 212, the rotation angle amplitude of the projector 200 in a direction facing the support structure 100 is 0 to 20°, and the rotation angle amplitude of the projector 200 in a direction away from the support structure 100 may be 0 to 5°. However, the rotation angle of the projector 200 along the rotary shaft 212 is not limited to the values ​​described above. For example, the rotation angle amplitude of the projector 200 in a direction facing the support structure 100 may also be 0 to 30°, and the rotation angle amplitude of the projector 200 in a direction away from the support structure 100 may be 0 to 15°, and the range of the rotation amplitude can be adjusted according to actual needs.

[0038] In some embodiments of the present application, the support structure 100 may further comprise a second support 120 connected to the first support 110.

[0039] As in Fig. 2, the second mount 120 is connected to the first mount 110, wherein the second mount 120 may comprise a first mounting frame 121 and a second mounting frame 122. The first mounting frame 121 is provided with two third openings 124, wherein the two third openings 124 of the first mounting frame 121 are used for connection to the rotary shaft 212 of the projector 200. The second mounting frame 122 is provided with two fourth openings 125, wherein the second mounting frame 122 may be fastened to the vehicle body by a third fastening element 430 passing through the fourth openings 125. In one possible embodiment, the two fourth openings 125 may be arranged offset, and the area of ​​the second mounting frame 122 is further reduced.This ensures that the support structure 100 is stably connected to the vehicle body and reduces the overall weight of the vehicle-mounted projector 200. It should be noted that the number of fourth openings 125 on the second mounting frame 122 may be two, but is not limited to two, but may also be three or four, for example. In one possible embodiment, the two ends of the first mounting frame 121 may also be provided with reinforcing members 126. The second fastening member 420 and the reinforcing members 126 connect the first mounting frame 121 to the vehicle body, thereby improving the stability of the connection between the support structure 100 and the vehicle body and preventing the support structure 100 from shaking or shifting during vehicle operation.

[0040] With further reference to Fig. 2 and Fig. 3, the first mounting frame 121 is connected to the second mounting frame 122. In one possible embodiment, the first mounting frame 121 and the second mounting frame 122 are provided with a plurality of triangular elements 123 toward the light-emitting side of the projector 200, whereby the triangular elements 123 can improve the supporting effect of the support structure 100 on the projector 200.
