[0024] Beneficial effects: In the present invention, the combined projection lamp, through the second motor driving the card connection structure between the rotating disk and the base, realizes the horizontal rotation of the lamp body, greatly increasing the flexibility and coverage of the projection. At the same time, the first motor cooperates with the worm gear reducer to accurately control the rotation angle of the lamp body in the support plate, meeting various projection requirements and improving the accuracy and practicality of the projection. The design of the card connection makes the connection between the rotating disk and the base more stable, and through the coordinated use of studs, nut rings, guide seats, plugs and connecting rods, a quick and simple disassembly and assembly process is achieved, which is convenient for maintenance and replacement of parts. The opening of the rectangular hole ensures the plug-in stability of the plug-in block and the fixed column, further enhancing the reliability of the structure;

The connection bar can move smoothly through the threaded cooperation of the third motor driving screw and the inner screw sleeve rod, and the guiding effect of the first guide rod, thereby driving the opening and closing of the protective shell, which not only protects the lamp body from external damage, but also facilitates the quick hiding of the lamp body when projection is not needed, thereby improving the aesthetics and safety of the equipment.

[0026] In the present invention, the combined projection lamp realizes the automatic cleaning function of the lamp head through the design of the cleaning component. When the two protective shells are close to each other and wrap the lamp body, the wedge block drives the rack to move, and then drives the sponge block to rotate and clean the lamp head through the meshing action of the gear ring and the rotating ring. This design not only simplifies the cleaning process, but also improves the cleaning efficiency and quality. At the same time, the addition of components such as the one-way bearing, the first spring, the third spring and the second spring makes the cleaning component more stable and reliable, and easy to maintain and replace;

[0027] In the present invention, the combined projection lamp, through the design of the limiting groove and the support frame at the bottom of the rotating ring and the fixing effect of the outer screw ring, enables the sponge block to be firmly installed in the rotating ring and rotate with the rotation of the rotating ring, and the setting of the sliding rod and the cleaning plate enables the sponge block to maintain a certain elasticity and adaptability during the cleaning process, so as to better fit the lamp head and clean the dirt and dust on its surface;

[0028] In the present invention, the setting of the first motor and the second motor not only makes it highly flexible and accurate, but also realizes effective protection and automatic cleaning functions of the lamp body through the design of the protective shell and the cleaning component, which not only improves the projection effect and quality, but also simplifies the maintenance and cleaning process of the equipment, and reduces the use cost and maintenance difficulty.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1: Reference Figure 1-Figure 8A combined projection lamp is used in the field of projection equipment, comprising: a mounting base 1 and a lamp body 3. A base 11 is rotatably provided at the bottom of the mounting base 1, and two support plates 2 are fixedly connected to the bottom of the base 11. The lamp body 3 is rotatably provided between the two support plates 2, and such a design allows the lamp body 3 to rotate in multiple directions to achieve multi-angle projection.

[0040] In order to realize the rotation of the base 11, a second motor 9 is fixedly arranged at the bottom of the mounting base 1. A rotating disk 10 is fixedly connected to the output end of the second motor 9, and the rotating disk 10 is connected to the base 11 through a clamping piece. The design of the clamping piece is as follows: a plurality of fixed columns 14 are fixed to the bottom of the rotating disk 10, and a socket 16 corresponding to the fixed columns 14 is provided at the top of the base 11. When the fixed columns 14 are inserted into the socket 16, the initial positioning of the rotating disk 10 and the base 11 is realized. In order to be more stable, a stud 19 is rotatably arranged at the bottom of the base 11, and a nut ring 20 is threadedly sleeved on the stud 19. A guide seat 17 corresponding to the socket 16 is also fixed to the top of the base 11, and an insert block 18 is slidably arranged in the guide seat 17. A rotating seat 21 corresponding to the insert block 18 is fixed to the outer wall of the nut ring 20, and a connecting rod 22 is rotatably connected between the rotating seat 21 and the insert block 18. The outer wall of the fixing column 14 is also provided with a rectangular hole 15 for plugging with the plug block 18. When the rotating disk 10 and the base 11 need to be fixed, the stud 19 is simply rotated to drive the plug block 18 to be inserted into the rectangular hole 15 through the connecting rod 22, so that a stable connection can be achieved. The second motor 9 can drive the lamp body 3 to rotate horizontally through the plugging of the rotating disk 10 and the base 11.

[0041] In order to realize the rotation of the lamp body 3 between the two support plates 2, a first motor 5 is fixedly arranged on one of the support plates 2, and a worm gear reducer 6 is fixedly connected to the output end of the first motor 5. The output end of the worm gear reducer 6 is connected to the rotating shaft of the lamp body 3. This design allows the first motor 5 to drive the lamp body 3 to rotate in the support plate 2 through the worm gear reducer 6, so as to realize the adjustment of the lamp body 3 in the vertical direction.

[0042] Two connecting strips 8 are respectively arranged on the outer sides of the two supporting plates 2. A connecting block 13 is fixedly arranged on one side of the two connecting strips 8 close to each other, and a protective shell 4 is fixedly arranged on one side of the connecting block 13. The two protective shells 4 are provided with a receiving cavity 28 adapted to the lamp body 3. When the protective shell 4 wraps around the lamp body 3, the lamp body 3 can be well protected.

[0043] In order to drive the two connecting strips 8 to move relative to each other, a driving mechanism is provided on the support plate 2. This driving mechanism comprises a support plate 23 fixedly arranged between the two support plates 2, and a third motor 24 is fixedly arranged at the bottom of the support plate 23. Both output ends of the third motor 24 are fixedly provided with a screw rod 25, and the outer wall thread sleeve of the screw rod 25 is provided with an inner screw sleeve rod 26. The end of the inner screw sleeve rod 26 away from the third motor 24 penetrates the support plate 2 and is fixedly connected with the corresponding connecting strip 8. When the third motor 24 is started, the two screw rods 25 can be driven to rotate simultaneously, and then the two inner screw sleeve rods 26 are driven to move to both sides respectively, thereby driving the two connecting strips 8 to approach or move away from each other, and realizing the opening and closing control of the protective shell 4.

[0044] Finally, a cleaning component is also provided at the bottom of the protective shell 4. After the two protective shells 4 wrap the lamp body 3, the cleaning component can automatically clean the lamp head on the lamp body 3 to ensure the clarity of the projection effect. Specifically, it includes a mounting plate 12 fixedly provided at the bottom of one of the protective shells 4. A rotating ring 29 is provided through the bottom of the mounting plate 12 for rotation. A sponge block 42 for cleaning the lamp head on the lamp body 3 is provided in the rotating ring 29. Due to its softness and water absorption, the sponge block 42 can effectively remove dust and stains on the lamp head to ensure the clarity of the projection.

[0045] A mounting cavity 37 is provided inside the mounting plate 12. A toothed ring 38 is sleeved on the outer wall of the rotating ring 29 and is located in the mounting cavity 37. A sliding groove 33 is provided on the outer wall of the mounting plate 12, and a rack 31 is slidably provided in the sliding groove 33 and meshed with the toothed ring 38. When the rack 31 slides in the sliding groove 33, the toothed ring 38 is driven to rotate, thereby driving the rotating ring 29 and the sponge block 42 to rotate together.

[0046] In order to achieve the sliding of the rack 31, a wedge block 32 is provided at the bottom of the other protective shell 4 for use with the rack 31. A contact groove 45 corresponding to the rack 31 is provided at the bottom of the wedge block 32. When the two protective shells 4 approach each other, the wedge block 32 will first contact the rack 31 and push it into the slide groove 33, thereby driving the gear ring 38 and the rotating ring 29 to rotate. As the two protective shells 4 continue to approach each other, the sponge block 42 will contact the lamp head and clean it.

[0047] In order to ensure that the rack 31 can be smoothly reset, a second guide rod 34 is fixedly arranged in the slide groove 33. A sliding block 36 is slidably sleeved on the outer wall of the second guide rod 34, and the sliding block 36 is fixedly arranged on one side of the rack 31. A first spring 35 is also sleeved on the second guide rod 34, and the two ends of the first spring 35 are respectively fixedly connected to one side of the sliding block 36 and one side of the inner wall of the slide groove 33. This design allows the first spring 35 to drive the rack 31 to reset after the wedge block 32 leaves the rack 31, preparing for the next cleaning.

[0048] Similarly, in order to ensure that the sponge block 42 can clean the lamp head, a mounting groove 46 is provided at the bottom of the protective shell 4 away from the mounting plate 12. Two third guide rods 47 are fixedly arranged in the mounting groove 46, and the wedge block 32 is slidably sleeved on the two third guide rods 47. A third spring 48 is sleeved on the outer wall of the third guide rod 47, and the two ends of the third spring 48 are fixedly connected to the bottom of the wedge block 32 and the top wall of the mounting groove 46 respectively. This design allows the third spring 48 to drive the wedge block 32 to reset after the two protective shells 4 are separated, preparing for the next cleaning process. In the process of the two protective shells 4 approaching each other, the rack 31 can be driven to move in the slide groove 33. Since the gear ring 38 is mounted on the rotating ring 29 through a one-way bearing, the movement of the rack 31 at this time can only drive the gear ring 38 to rotate, but will not drive the rotating ring 29 to rotate. The two protective shells 4 continue to approach each other, allowing the sponge block 42 to contact the lamp holder. In the process of continued movement, the wedge block 32 can be squeezed into the mounting groove 46 through the mounting plate 12. At this time, the rack 31 can reset and move under the action of the first spring 35, and drive the gear ring 38 to rotate. At this time, the reverse rotation of the gear ring 38 can drive the sponge block 42 to rotate through the reverse bearing to clean the lamp holder.

[0049] Example 2: Reference Figure 1-Figure 8 , improved on the basis of Example 1: In addition, in order to guide the connecting strip 8, a first guide rod 27 is slidably provided on one side of the support plate 2, and the first guide rod 27 is fixedly connected to the corresponding connecting strip 8. This design can ensure that the connecting strip 8 remains stable during the movement without deviation or shaking.

[0050] Two protective covers 7 are also provided on the top of the two connecting strips 8. The two protective covers 7 are used in conjunction with the mounting seat 1 and the base 11, respectively, to limit the base 11 and to provide good protection for the clamping parts.

[0051] In addition, the rotating ring 29 is specially designed. A plurality of limit grooves 39 are provided at the bottom of the rotating ring 29, and a common support frame 30 is arranged in these limit grooves 39. An outer screw ring 44 is also threadedly arranged in the rotating ring 29 to interfere with the support frame 30. By rotating the outer screw ring 44, the support frame 30 can be fixed in the rotating ring 29. This design can make the sponge block 42 stable when cleaning the lamp head, and will not shake or fall off, and due to the setting of the support frame 30, the cleaned impurities can fall automatically.

[0052] In order to prevent the sponge block 42 from getting stuck with the lamp holder, a sliding rod 40 is slidably provided at the bottom of the support frame 30. A cleaning plate 41 is fixedly provided on the top of the sliding rod 40, and the sponge block 42 is fixedly provided on the top of the cleaning plate 41. A second spring 43 is also sleeved on the outer wall of the sliding rod 40, and the two ends of the second spring 43 are respectively fixedly connected to the supporting frame 30 and the side of the cleaning plate 41 close to each other. This design can ensure that when the sponge block 42 contacts the lamp holder, there is a certain elastic buffer to avoid damage to the lamp holder. At the same time, after cleaning, the second spring 43 can also drive the cleaning plate 41 and the sponge block 42 to reset, preparing for the next cleaning process.

[0053] A method for using a combined projection lamp comprises the following steps:

[0054] S1. First, the device is powered on, and then the third motor 24 is started to drive the two connecting strips 8 away from each other, and then the mounting base 1 is installed in the mounting area, and then the base 11 is plugged into the rotating disk 10;

[0055] S2. When the angle needs to be adjusted, the first motor 5 is started to drive the lamp body 3 to rotate between the two support plates 2, and the second motor 9 is started to drive the lamp body 3 to rotate horizontally until it is adjusted to the projection area;

[0056] S3, when the lamp body 3 is turned off during the day, the second motor 9 and the first motor 5 are started to drive the lamp body 3 to reset and rotate, and then the third motor 24 is started to drive the two connecting bars 8 to approach each other, and during the approaching process, the two protective covers 7 can be driven to wrap the mounting seat 1 and the base 11, and the two protective shells 4 can be driven to wrap the lamp body 3 to limit the position of the lamp body 3;

[0057] S4. After the two protective shells 4 are close to each other, they can drive the sponge block 42 to rotate to clean the lamp head, and the cleaned impurities can fall off automatically.

[0058] In the present application, first, the device is powered on, and then the third motor 24 is started to drive the two screw rods 25 to rotate. The rotation of the screw rod 25 can drive the inner screw sleeve rod 26 to move outward on the support plate 2, so that the two connecting strips 8 can be driven to move away from each other. During the movement of the connecting strip 8, the corresponding protective shell 4 and protective cover 7 can be driven to move at the same time, so that the lamp body 3 can be exposed. Then the mounting base 1 is installed in the mounting area, and then the position of the plug block 18 is checked. When the plug block 18 blocks the insertion hole 16, the stud 19 is rotated in the opposite direction to drive the nut ring 20 to move downward. The downward movement of the nut ring 20 can drive the plug block 18 to move on the base 11 through the rotating seat 21 until the plug block 18 is away from the insertion hole 16. Then the base 11 is placed on the rotating disk 10. After insertion, the stud 19 is rotated again to drive the nut ring 20 to move upward. The upward movement of the nut ring 20 can drive the plug block 18 to move through the corresponding rotating seat 21 until the plug block 18 is inserted into the corresponding rectangular hole 15. At this time, the installation of the base 11 is completed;

[0059] When the angle needs to be adjusted, the first motor 5 is started to drive the worm gear reducer 6 to rotate, and the rotation of the worm gear reducer 6 can drive the lamp body 3 to rotate between the two support plates 2, and the second motor 9 can be started to drive the rotating disk 10 to rotate. During the rotation of the rotating disk 10, the base 11 can be driven to rotate through the fixing column 14 and the socket 16, so that the lamp body 3 can be rotated in the horizontal direction until it is adjusted to the projection area;

[0060] When the lamp body 3 is turned off during the day, the second motor 9 and the first motor 5 are started to drive the lamp body 3 to reset and rotate, and then the third motor 24 is started to drive the two connecting bars 8 to approach each other. During the approaching process, the two protective covers 7 can be driven to wrap the mounting seat 1 and the base 11, and the two protective shells 4 can be driven to wrap the lamp body 3 to limit the position of the lamp body 3;

[0061] At the same time, when the two protective shells 4 approach each other, the rack 31 can move in the slide groove 33 through the interference groove 45. During the movement of the rack 31, the gear ring 38 can be driven to rotate. Due to the effect of the one-way bearing, the rotation of the gear ring 38 will not drive the rotating ring 29 to rotate. During the movement, the rack 31 can drive the sliding block 36 to move on the second guide rod 34 and compress the first spring 35. When the mounting plate 12 contacts the wedge block 32, the wedge block 32 can move upward under the thrust of the mounting plate 12. When the interference groove 45 is disengaged from the rack 31, the rack The rack 31 can be reset and moved under the action of the first spring 35, and the reset movement of the rack 31 drives the gear ring 38 to rotate. At this time, the rotation of the gear ring 38 can drive the rotating ring 29 to rotate through the one-way bearing, and the rotation of the rotating ring 29 can drive the support frame 30 to rotate through the limit groove 39. The rotation of the support frame 30 can drive the cleaning plate 41 to rotate through the sliding rod 40. During the rotation of the cleaning plate 41, the sponge block 42 can be driven to rotate on the lamp head, so as to clean the impurities on the lamp head. Since the protective shell 4 faces downward after installation, the cleaned impurities can be automatically discharged;

[0062] When the sponge block 42 needs to be replaced, the outer screw ring 44 is rotated to move the outer screw ring 44 in the rotating ring 29 until the outer screw ring 44 is separated from the rotating ring 29. At this time, the support frame 30 can be taken out from the limiting groove 39 and the sponge block 42 can be replaced.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the lamp body 3, the first motor 5, the second motor 9 and the third motor 24 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
