[0036] The number of gear mounting portions 120 is substantially the same as the number of gears 310 included in the transmission mechanism 30, or the number of gear mounting portions 120 is greater than or equal to the number of gears 310, in order to facilitate the expansion of the number of gear transmission stages in the transmission mechanism 30. The distance between any two gear mounting portions 120 is approximately equal to the center distance of the gears 310 mounted on the two gear mounting portions 120 respectively.

[0037] Optionally, the first substrate 110 further includes at least one first support connecting portion 130. The first support connecting portion 130 is used to fixably connect the first support 10 and the second support 20. The number of first support connecting portions 130 can be one or more, for example, the number of first support connecting portions 130 can be determined according to the fixing strength requirements of the first substrate 110. Specifically, in this embodiment, the first substrate 110 is provided with a plurality of first support connecting portions 130, which are distributed at intervals on one side of the first substrate 110 facing the second substrate 210.

[0040] Please see Figure 3 In this embodiment, the second support 20 includes a second base plate 210, which is generally plate-shaped and is used to cooperate with the first base plate 110 to achieve unified assembly of the multiple gears 310 included in the transmission mechanism 30. The size of the second base plate 210 is determined according to the number of gears 310 included in the transmission mechanism 30 and the size of the gear body 3110 of each gear 310.

Figure 1 as well as Figure 5 The first substrate 110 and the second substrate 210 are arranged at intervals to form an assembly space 200, and the first substrate 110 and the second substrate 210 are fixedly connected. In this embodiment, the second substrate 210 is provided with a plurality of gear connecting portions 220, and the plurality of gear connecting portions 220 correspond one-to-one with the plurality of gear mounting portions 120 and are arranged opposite to each other.

[0042] The gear connecting part 220 is used to connect the corresponding gear 310, thereby realizing the assembly of the gear 310. The gear connecting part 220 and the corresponding gear mounting part 120 are designed to be approximately coaxial.

[0043] The gear connecting portion 220 is a shaft hole or groove structure formed on the second substrate 210 that mates with the shaft 3120 of the corresponding gear 310. Specifically, in this embodiment, the gear connecting portion 220 is generally cylindrical, which is generally perpendicular to the second substrate 210 and protrudes toward the first substrate 110. This cylindrical structure has a shaft hole or groove structure that mates with the shaft 3120 of the corresponding gear 310.

[0044] Furthermore, when the gear 310 corresponding to the gear connecting part 220 is an output gear, the gear connecting part 220 is a through hole penetrating the second substrate 210 so that the shaft of the output gear can be exposed on the second substrate 210, which is beneficial for mounting optical devices.

[0045] The number of gear connecting parts 220 is basically the same as the number of gear mounting parts 120. The distance between any two gear connecting parts 220 is approximately equal to the center distance of the gears 310 connected to the two gear connecting parts 220 respectively.

[0046] Furthermore, the second substrate 210 is also provided with at least one second bracket connecting portion 230. The second bracket connecting portion 230 is used to cooperate with the first bracket connecting portion 130 to achieve a fixed connection between the first bracket 10 and the second bracket 20. The number of second bracket connecting portions 230 is substantially equal to the number of first bracket connecting portions 130. Specifically, in this embodiment, the second substrate 210 is provided with a plurality of second bracket connecting portions 230, which are distributed at intervals on the side of the second substrate 210 facing the first substrate 110.

[0047] Specifically, in this embodiment, the second bracket connecting portion 230 is generally a protruding column structure, protruding along the surface of the second substrate 210 toward the first substrate 110. The second bracket connecting portion 230 has a second connecting cavity, which is adapted to house a connector for fixing the first bracket 10 and the second bracket 20. The second connecting cavity can be a threaded through hole, and the second bracket connecting portion 230 is a threaded column with a threaded through hole. In other possible embodiments, the second bracket connecting portion 230 is a connecting hole formed on the second substrate 210, or the second bracket connecting portion 230 is a hollow column.

[0048] At least one first bracket connecting part 130 and at least one second bracket connecting part 230 are provided in a one-to-one correspondence, and each first bracket connecting part 130 is fixedly connected to the corresponding second bracket connecting part 230. The connection structure between the first bracket connecting part 130 and the second bracket connecting part 230 includes any of the following structures: threaded fastening connection, hole-shaft interference fit connection, and snap-fit ​​connection.

[0049] Optionally, at least one of the first bracket connecting portion 130 and the second bracket connecting portion 230 is a protruding column structure. Specifically, in this embodiment, both the first bracket connecting portion 130 and the second bracket connecting portion 230 are protruding column structures, and their end faces abut and support each other between the first substrate 110 and the second substrate 210.

[0050] Further, please refer to Figure 4 The transmission device 100 further includes at least one second connector 40, which is provided in a one-to-one correspondence with at least one first bracket connection portion 130 and at least one second bracket connection portion 230; each second connector 40 is connected between the corresponding second bracket connection portion 230 and the corresponding first bracket connection portion 130.

[0051] Specifically, in this embodiment, the second connector 40 is the first bolt. The end face of the first bracket connecting portion 130 is provided with a first threaded inner hole. The contact position between the second bracket connecting portion 230 and the second substrate 210, and the second bracket connecting portion 230 is provided with a first threaded through hole that mates with the aforementioned first threaded inner hole. The first bolt passes through this first threaded through hole and connects to the first threaded inner hole. In other possible embodiments, the second bracket connecting portion 230 is sleeved on the first bracket connecting portion 130. The side of the first bracket connecting portion 130 is provided with a second threaded inner hole. The second bracket connecting portion 230 is provided with a second threaded through hole that mates with the second threaded inner hole. The first bolt passes through this second threaded through hole and connects to the second threaded inner hole.

[0052] In other possible implementations, one of the first bracket connecting portion 130 and the second bracket connecting portion 230 is a protruding pillar structure. For example, the second bracket connecting portion 230 is a protruding pillar structure, the first bracket connecting portion 130 is a connecting hole formed on the first substrate 110, the second bracket connecting portion 230 passes through the first bracket connecting portion 130, and the first bracket connecting portion 130 and the second bracket connecting portion 230 are fixedly connected by an interference fit between the hole and the shaft. As another example, the second bracket connecting portion 230 is a protruding pillar structure, the first bracket connecting portion 130 is a hollow pillar that mates with the protruding pillar structure, and the first bracket connecting portion 130 is sleeved on the second bracket connecting portion 230 to achieve a fixed connection between the first bracket connecting portion 130 and the second bracket connecting portion 230. For example, the first bracket connecting portion 130 is a protruding column structure, and the second bracket connecting portion 230 is a connecting hole formed on the second substrate 210. The first bracket connecting portion 130 passes through the second bracket connecting portion 230, and the first bracket connecting portion 130 and the second bracket connecting portion 230 are fixedly connected by an interference fit between the hole and the shaft. Alternatively, the first bracket connecting portion 130 is a protruding column structure, and the second bracket connecting portion 230 is a hollow column that mates with the protruding column structure. The second bracket connecting portion 230 is sleeved on the first bracket connecting portion 130 to achieve a fixed connection between the first bracket connecting portion 130 and the second bracket connecting portion 230.

[0053] Furthermore, please refer to again Figure 1 as well as Figure 3 The second substrate 210 is also provided with a plurality of limiting portions 240, which are respectively provided with a plurality of gear bodies 3110; the limiting portions 240 abut against the end face of the corresponding gear body 3110. The limiting portions 240 are used to limit the corresponding gear body 3110, so as to prevent the corresponding gear body 3110 from moving back and forth along the length direction of the shaft 3120 during rotation, thereby improving the working stability of the gear 310.

[0054] For details in this embodiment, please refer to Figure 1 , Figure 6 , Figure 7The limiting part 240 includes a limiting protrusion 2410 surrounding the outer periphery of the corresponding rotating shaft 3120. The end face of the gear body 3110 is provided with a mating protrusion 3111 corresponding to the limiting protrusion 2410. The end face of the limiting protrusion 2410 abuts against the corresponding mating protrusion 3111.

[0055] Please see Figure 1 , Figures 4-7 The transmission mechanism 30 includes multiple gears 310. A gear 310 is a mechanical structure with teeth on its rim, capable of continuous meshing to transmit motion and power. In this embodiment, the gears 310 are used to drive optical devices to rotate along a designated axis. In this embodiment, the multiple gears 310 are divided into at least two groups, and each group of gears 310 may include one or more gears 310. Gears 310 in different groups are used to drive different optical devices respectively, thereby forming different light effects with different motion patterns, making the light effects of the lamp equipped with the transmission device 100 more diverse. Further, each group of gears 310 has at least one output gear, which is used to mount and drive the optical device to rotate. Therefore, there may be at least two output gears among the multiple gears 310, which are used to drive at least two optical devices to rotate respectively. As an example, the transmission device 100 also includes at least two optical devices 50. The output gears in the at least two groups of gears 310 correspond one-to-one with the at least two optical devices 50.

[0056] Furthermore, in some embodiments, the plurality of gears 310 may include one or more driving gears, which drive the output gear to rotate. As an example, at least two sets of gears 310 may have one driving gear, with the other gears driven by this driving gear. As another example, each set of gears 310 may have at least one output gear and one driving gear, with the remainder being intermediate transmission gears or excluding intermediate transmission gears. The driving gear, intermediate rotating gears (if any), and output gear mesh sequentially. The driving gear is typically directly driven by a motor or other power source, responsible for transmitting power to the output gear through the intermediate transmission gears. The intermediate transmission gears change the torque and direction of motion, and their power source is the rotation of the driving gear. Each gear 310 includes a gear body 3110 and a shaft 3120 connected to the gear body 3110. Multiple gear bodies 3110 of gears 310 located in the same set mesh sequentially, thereby enabling the driving gear to drive the other gears to rotate. One end of the rotating shaft 3120 is rotatably connected to the corresponding gear mounting part 120, and the other end of the rotating shaft 3120 is rotatably connected to the corresponding gear connecting part 220. In this way, the rotating shaft 3120 can rotate freely to drive other structures mounted on the rotating shaft 3120 to rotate.

[0057] In addition, please refer to Figure 7In this embodiment, among the multiple gears 310, there are at least two output gears 311. The output gears 311 are used to mount and drive the optical device to rotate. The rotating shaft 3120 of each output gear 311 includes a first shaft portion (not shown in the figure) and a second shaft portion 3122 connected to each other. The first shaft portion is connected to the corresponding gear body 3110 and rotatably connected to the corresponding gear mounting portion 120. The second shaft portion 3122 passes through the through hole and is exposed on the side of the second substrate 210 opposite to the first substrate 110.

[0058] Please refer to Figure 6 This diagram illustrates the structure of a transmission device 100 according to an embodiment of this application. Specifically, in this embodiment, the transmission device 100 further includes at least two optical components 50. The optical components 50 are used to relay light and project it onto a projection screen, for example, to adjust the projection angle, the projection pattern, or the projection light effect. Each of the at least two optical components 50 corresponds one-to-one with the aforementioned at least two output gears 311. Please refer to... Figure 7 Each optical element 50 is connected to the second shaft 3122 of the corresponding output gear 311. In this way, the rotation of the output gear 311 can drive the corresponding optical element 50 to rotate around the second shaft 3122, thereby adjusting the projection angle and imaging effect.

[0059] Furthermore, the optical device 50 includes a texture sheet 510 and a connecting shaft portion 520. The texture sheet 510 is used to project light onto a projection screen to form a specific lighting effect, such as a starry sky effect or a specific pattern lighting effect. The texture sheet 510 in the plurality of optical devices 50 includes at least one of the following structures: a film projection sheet, a grating projection sheet. The connecting shaft portion 520 is used to fix and connect the texture sheet 510 and the second shaft portion 3122.

[0060] Specifically, the connecting shaft portion 520 is disposed on one side of the texture sheet 510, and the texture sheet 510 is sleeved on the end of the second shaft portion 3122 via the connecting shaft portion 520. Compared with the related technology, which uses drilling holes in the texture sheet body to achieve a fixed connection between the texture sheet and the rotating shaft via bolts, the technical solution provided in this application embodiment can avoid the potential danger of damage to the texture sheet body caused by drilling, and improve the service life of the texture sheet.

[0061] Furthermore, please refer to again Figure 6The transmission device 100 further includes a first connecting member 60, which passes radially through the connecting shaft portion 520 along the second shaft portion 3122 and connects the second shaft portion 3122 and the connecting shaft portion 520. The first connecting member 60 is used to fix the second shaft portion 3122 and the connecting shaft portion 520. The first connecting member 60 may be a second bolt. Optionally, the second shaft portion 3122 has a threaded inner hole in the radial direction, and the connecting shaft portion 520 has a threaded through hole that mates with the threaded inner hole. The second bolt passes through the threaded through hole and connects to the threaded inner hole, thereby achieving a fixed connection between the second shaft portion 3122 and the connecting shaft portion 520.

[0062] The transmission device 100 provided in this application embodiment may further include a driving member (not shown in the figure). The driving member is driven to the drive gear and is used to drive the drive gear to rotate. The number of driving members is approximately the same as the number of drive gears. For example, when there is one drive gear in multiple sets of gears 310, the number of driving members can be one, and one driving member is connected to the corresponding drive gear, thereby simultaneously driving at least two output gears 311 to rotate, which is beneficial to forming synchronous changes (e.g., synchronous rotation, synchronous forward rotation and reverse rotation) light effects; as another example, when each set of multiple sets of gears 310 has a drive gear, the number of driving members can be multiple, and each driving member is connected to the corresponding drive gear and drives the output gear in that set of gears 310 to rotate, which is beneficial to make the optical device 50 corresponding to each set of gears 310 form different light effects, and also facilitates the independent control of these light effects. Further, the driving member may include a driving circuit and a driving motor electrically connected to the driving circuit, and the driving motor is driven to the corresponding drive gear. The driving member is disposed on the side of the first substrate 110 opposite to the second substrate 210.
