[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a vehicle-mounted projector.

[0023] Reference Figure 1 and Figure 2The vehicle-mounted projector includes a housing 1 mounted on the roof of the vehicle, with a mounting shell 2 connected to the housing 1. The projector is installed inside the mounting shell 2, which has a projection port corresponding to the projection end of the projector. The housing 1 contains a lifting device for raising and lowering the mounting shell 2 relative to the housing 1, and a rotating device for rotating the mounting shell 2. Therefore, activating the lifting device raises and lowers the mounting shell 2 relative to the housing 1, and activating the rotating device rotates the mounting shell 2, enabling both linear and rotational movement of the mounting shell 2 and the projector. Passengers can adjust the position of the projector according to their needs, offering high flexibility and allowing projection from different angles. The integrated vertical and rotational movement of the projector results in a compact structure, meeting the needs of limited vehicle space while expanding the functional range of the vehicle-mounted projector.

[0024] Reference Figure 2 and Figure 3 The lifting device includes a card plate 3 mounted on the mounting shell 2. The outer edge of the mounting shell 2 is provided with an annular groove 32 that matches the size of the card plate 3. The card plate 3 is partially inserted into the annular groove 32, and the end face of the card plate 3 contacts the groove wall of the annular groove 32. The annular groove 32 limits the position of the card plate 3 and reduces the possibility of the card plate 3 moving around.

[0025] Reference Figure 2 and Figure 3 A first lead screw 4 is rotatably connected to the housing 1. A first bushing 38 and a second bushing 39 are provided on the housing 1. The two ends of the first lead screw 4 are rotatably connected to the inner edges of the first bushing 38 and the second bushing 39, respectively. The first bushing 38 and the second bushing 39 can be made of copper alloy material. Under the condition of lack of lubricant, copper bushings still have good sliding and self-lubricating properties. The first bushing 38 and the second bushing 39 provide support for the first lead screw 4 and reduce the direct friction between the first lead screw 4 and the housing 1, reduce the wear of the first lead screw 4, and help maintain the stability of the first lead screw 4 during rotation. The outer edge of the first lead screw 4 is threaded with a first nut 5 that matches the size of the first lead screw 4. The first nut 5 is bolted to the clamping plate 3. A first drive unit for driving the rotation of the first lead screw 4 is provided on the housing 1. The first drive unit includes a first drive motor 6 provided on the housing 1. A lifting gear 7 is fixedly sleeved on one end of the first lead screw 4. The output end of the first drive motor 6 is connected to the lifting gear 7 through a transmission assembly.

[0026] Reference Figure 2 and Figure 3The transmission assembly includes a first worm 8 disposed at the output end of the first drive motor 6, a first mounting shaft 9 mounted on the housing 1, a first connecting sleeve 10 rotatably connected to the outer edge of the first mounting shaft 9, and a first gear 11 whose size matches that of the lifting gear 7 fixedly connected to the outer edge of the first connecting sleeve 10. In this embodiment, the first gear 11 and the first connecting sleeve 10 are integrally formed and mesh with each other. The outer edge of the first connecting sleeve 10 is fixedly sleeved with a first worm wheel 12 whose size matches that of the first worm 8, and the first worm 8 and the first worm wheel 12 mesh with each other.

[0027] Therefore, starting the first drive motor 6 drives the first worm 8 at the output end of the first drive motor 6 to rotate. Since the first worm 8 and the first worm wheel 12 mesh with each other, the first worm 8 drives the first worm wheel 12 to rotate. The first worm wheel 12 drives the first connecting sleeve 10 and the first gear 11 to rotate synchronously. Since the first gear 11 and the lifting gear 7 mesh with each other, the first gear 11 drives the lifting gear 7 to rotate. The lifting gear 7 drives the first lead screw 4 to rotate, causing the first nut 5 to move along the length direction of the first lead screw 4. The first nut 5 drives the clamping plate 3 and the mounting shell 2 to rise and fall synchronously, realizing the adjustable raising and lowering of the vertical position of the projector inside the mounting shell 2.

[0028] Reference Figure 2 and Figure 3 The housing 1 is also rotatably connected to a second lead screw 13 and a third lead screw 14. In this embodiment, the first lead screw 4, the second lead screw 13 and the third lead screw 14 are the same size and their center lines are parallel to each other. The housing 1 can also be provided with bushings corresponding to the assembly positions of the second lead screw 13 and the third lead screw 13, with reference to the setting of the first lead screw 4. The outer edge of the second lead screw 13 is threaded with a second nut 15 that matches the size of the second lead screw 13. The outer edge of the third lead screw 14 is threaded with a third nut 16 that matches the size of the third lead screw 14. The second nut 15 and the third nut 16 are both bolted to the clamping plate 3. The housing 1 is provided with a connecting unit for driving the second lead screw 13 and the third lead screw 14 to rotate synchronously with the first lead screw 4. The connecting unit includes a first synchronous wheel 17 coaxially arranged on the first lead screw 4. In this embodiment, the lifting gear 7 is located between the first synchronous wheel 17 and the first nut 5. The second synchronous wheel 18 is coaxially fixedly sleeved on the second lead screw 13. The third synchronous wheel 19 is coaxially fixedly sleeved on the third lead screw 14. A synchronous belt 20 is tautly wound between the first synchronous wheel 17, the second synchronous wheel 18 and the third synchronous wheel 19.

[0029] Therefore, the rotation of the first lead screw 4 drives the rotation of the first synchronous pulley 17. The first synchronous pulley 17 drives the second synchronous pulley 18 and the third synchronous pulley 19 to rotate synchronously via the synchronous belt 20. The second synchronous pulley 18 drives the second lead screw 13 to rotate, and the third synchronous pulley 19 drives the third lead screw 14 to rotate, causing the second nut 15 to move along the length direction of the second lead screw 13 and the third nut 16 to move along the length direction of the third lead screw 14. The first nut 5, the second nut 15, and the third nut 16 move the clamping plate 3 up and down synchronously via the synchronous belt 20. From multiple positions on the outer edge of the mounting shell 2, they jointly drive the mounting shell 2 to move up and down relative to the shell 1, improving the stability of the mounting shell 2 during the movement process.

[0030] Reference Figure 2 and Figure 3 A support column 40 is installed on the housing 1. The support column 40 passes through the clamping plate 3. A first tensioning wheel 21 is rotatably connected to the support column 30. The first tensioning wheel 21 is located between the synchronous belt 20 and the projector and is pressed against the synchronous belt 20. The position of the synchronous belt 20 is limited by the first tensioning wheel 21, thereby restricting the layout of the synchronous belt 20 and facilitating the operator's convenience when assembling the projector into the housing 2.

[0031] Reference Figure 2 and Figure 3 A movable block 22 is slidably connected to the housing 1. Two opposing sliders 30 are fixedly connected to the surface of the housing 1 facing the movable block 22. A groove matching the size of the two sliders 30 is opened on the surface of the movable block 22 facing the sliders 30. The sliders 30 are slidably connected in the groove and limit the groove, thereby limiting the sliding direction of the movable block 22, so that the movable block 22 can only move along the setting of the sliders 30, reducing the possibility of position deviation during the movement of the movable block 22.

[0032] Reference Figure 2 and Figure 3 A fixing bolt 26 is installed on the housing 1. A waist-shaped hole 27 matching the size of the fixing bolt 26 is provided on the movable block 22. A waist-shaped groove is formed on the wall of the waist-shaped hole 27. In this embodiment, the waist-shaped hole 27 is located on the end face of the sliding block facing the adjusting block 24. The extension direction of the waist-shaped groove is consistent with the extension direction of the waist-shaped hole 27. A fixing nut matching the size of the waist-shaped groove is slidably connected inside the waist-shaped groove. The end of the fixing bolt 26 facing the fixing nut is threadedly connected to the fixing nut. The fixing bolt 26 and the fixing nut reduce the possibility of lateral rotation of the movable block 22, further improving the stability of the movable block 22 during movement.

[0033] Reference Figure 2 and Figure 3A second tensioning wheel 23 is rotatably connected to the movable block 22. The height of the second tensioning wheel 23 and the first tensioning wheel 21 is the same as the height of the synchronous belt 20. The second tensioning wheel 23 is located on one side of the synchronous belt 20 and abuts against the synchronous belt 20. The housing 1 is provided with a moving unit for driving the movable block 22 to slide. The moving unit includes an adjusting block 24 fixedly connected to the housing 1. The adjusting block 24 and the housing 1 are integrally formed. An adjusting screw 25 is threaded through and connected to the adjusting block 24. The end of the adjusting screw 25 facing the movable block 22 contacts the movable block 22. Therefore, when the synchronous belt 20 becomes loose, the operator rotates the adjusting screw 25. The end of the adjusting screw 25 pushes the movable block 22 to slide along the slider 30. During the movement of the movable block 22, it drives the second tensioning wheel 23 to move towards the mounting housing 2, thereby adjusting the tightness between the second tensioning wheel 23 and the synchronous belt 20.

[0034] Reference Figure 2 and Figure 3 The rotating device includes a gear ring 34 mounted on the outer edge of the mounting shell 2. A mounting block 35 is bolted to the clamping plate 3. A second connecting shaft 36 is mounted on the mounting block 35. A rotating gear 37 matching the size of the gear ring 34 is rotatably connected to the outer edge of the second connecting shaft 36. The rotating gear 37 meshes with the gear ring 34. A second driving unit for driving the rotating gear 37 to rotate is provided on the mounting block 35. The second driving unit includes a second driving motor 33 mounted on the mounting block 35. A second worm gear 31 is mounted on the output end of the second driving motor 33. A second connecting sleeve 29 is rotatably connected to the outer edge of the second connecting shaft 36. The rotating gear 37 is mounted on the second connecting sleeve 29. In this embodiment, the second connecting sleeve 29 and the rotating gear 37 can be integrally formed. A second worm wheel 28 matching the size of the second worm gear 31 is fixedly sleeved on the outer edge of the second connecting sleeve 29. The second worm wheel 28 and the second worm gear 31 mesh with each other.

[0035] Therefore, the second drive motor 33 is started, which drives the second worm 31 at the output end of the second drive motor 33 to rotate. Since the second worm 31 and the second worm wheel 28 mesh with each other, the second worm wheel 28 drives the rotating gear 37 to rotate during rotation. Since the rotating gear 37 meshes with the gear ring 34, the rotating gear 37 drives the gear ring 34 to rotate. During the rotation of the gear ring 34, the mounting shell 2 rotates synchronously, thereby realizing the rotation of the projector inside the mounting shell 2.

[0036] The implementation principle of this application embodiment is as follows: the first drive motor 6 is started, which drives the first worm 8 at the output end of the first drive motor 6 to rotate. Since the first worm 8 and the first worm wheel 12 are meshed with each other, the first worm 8 drives the first worm wheel 12 to rotate. The first worm wheel 12 drives the first connecting sleeve 10 and the first gear 11 to rotate synchronously. Since the first gear 11 and the lifting gear 7 are meshed with each other, the first gear 11 drives the lifting gear 7 to rotate. The lifting gear 7 drives the first lead screw 4 to rotate, so that the first nut 5 moves along the length direction of the first lead screw 4. The first nut 5 drives the clamping plate 3 and the mounting shell 2 to rise and fall synchronously, so as to realize the adjustable rise and fall of the vertical position of the projector in the mounting shell 2.

[0037] The rotation of the first lead screw 4 drives the first synchronous pulley 17 to rotate. The first synchronous pulley 17 drives the second synchronous pulley 18 and the third synchronous pulley 19 to rotate synchronously via the synchronous belt 20. The second synchronous pulley 18 drives the second lead screw 13 to rotate, and the third synchronous pulley 19 drives the third lead screw 14 to rotate, causing the second nut 15 to move along the length direction of the second lead screw 13 and the third nut 16 to move along the length direction of the third lead screw 14. The first nut 5, the second nut 15, and the third nut 16 move the clamping plate 3 up and down synchronously via the synchronous belt 20. From multiple positions on the outer edge of the mounting shell 2, they jointly drive the mounting shell 2 to move up and down relative to the shell 1, which improves the stability of the mounting shell 2 during the movement process.

[0038] The second drive motor 33 is started, which drives the second worm 31 at the output end of the second drive motor 33 to rotate. Since the second worm 31 and the second worm wheel 28 mesh with each other, the second worm wheel 28 drives the rotating gear 37 to rotate during rotation. Since the rotating gear 37 meshes with the gear ring 34, the rotating gear 37 drives the gear ring 34 to rotate. During the rotation of the gear ring 34, the mounting shell 2 rotates synchronously, thereby realizing the rotation of the mounting shell 2 and the projector.

[0039] The lifting and rotating devices enable the vertical linear and rotational movement of the mounting housing 2 and the projector. Passengers can adjust the position of the projector in the vehicle according to their actual needs, which is highly flexible and allows the projector to project from different directions. The integrated vertical and vertical movement and rotation of the projector results in a compact structure that meets the needs of use in small vehicle spaces while increasing the functional range of the vehicle projector.
