Description

Technical Field

[0001] The present application relates to the technical field of camera equipment, and in particular to a photographic slide device. Background Art

[0002] A camera slide is a device used to assist in the movement of a camera, electronically controlled pan / tilt head, or other related modules. It allows the camera to shoot from a variety of positions, satisfying the photographer's desired angles. A camera slide not only allows for horizontal movement of the camera but also, in conjunction with the electronically controlled pan / tilt head, allows the camera to rotate simultaneously around two different axes.

[0003] However, in order for an electronically controlled gimbal to rotate the camera around an independent axis, traditional camera slides require separate batteries for each rotation drive module and separate control. Furthermore, the rotation control of different axes relies on a Bluetooth connection for coordination. However, Bluetooth connections are unstable and prone to signal delays, resulting in inaccurate synchronization between different axes and a poor user experience. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0038] Figures 1 to 12 FIG. 1 shows a photographic slide rail device 100 according to at least one embodiment of the present invention. Figure 1 As shown, the present application provides a photographic slide device 100 for mounting and connecting an electric control mounting platform 900. The photographic slide device 100 can drive the electric control mounting platform 900 to move along a straight path and rotate around a first axis.

[0039] Combine Figure 4 and Figure 5 As shown, the electrically controlled mounting platform 900 is used to mount or connect a camera and includes an electrically controlled device. The electrically controlled mounting platform 900 can be a camera electronically controlled gimbal, configured to drive the camera to rotate about one or more axes different from the first axis. The electrically controlled mounting platform 900 can also be a stabilizer, configured to eliminate camera shake.

[0040] It can be understood that the photographic slide rail device 100 is also used to install a quick release plate, which is used to directly fix a camera or other photographic equipment.

[0041] Specifically, combined Figures 5 to 7As shown, the photographic slide device 100 includes: a base 20, a control assembly 21, a slide 30, a shaft platform 40, and a conductive slip ring 50. The control assembly 21 is installed in the base 20. The slide 30 is slidably mounted on the base 20. The electrical module 31 is fixedly installed in the slide 30 and is electrically connected to the control assembly 21. The shaft platform 40 is rotatably mounted on the slide 30. The shaft platform 40 is used to connect to the electronic control mounting platform 900 of the camera. The shaft platform 40 is provided with a conductive terminal 41 for forming an electrically conductive contact with the electronic control mounting platform 900. The conductive slip ring 50 is electrically connected to the conductive terminals 41 of the electrical module 31 and the shaft platform 40 respectively.

[0042] Specifically, the electric control mounting platform 900 has contact terminals 901 for electrically connecting to the conductive terminals 41. After the electric control mounting platform 900 is mounted on the pillow block 40 of the photographic slide device 100 of the present application, the contact terminals 901 of the electric control mounting platform 900 and the electrical module 31 form conductive contact via the conductive terminals 41 of the pillow block 40 and the conductive slip ring 50, thereby achieving electrical connection.

[0043] The conductive slip ring 50 includes a rotating portion 52 and a fixed portion 51 . The rotating portion 52 can rotate relative to the fixed portion 51 , and is in sliding contact with and electrically connected to the fixed portion 51 , thereby forming a stable electrical connection during rotation.

[0044] In this embodiment, the rotating portion 52 of the conductive slip ring 50 is fixedly connected to the pillow block 40 and rotates with the pillow block 40. The fixed portion 51 is fixedly connected to the slide 30. The fixed portion 51 is electrically connected to the electrical module 31, and the rotating portion 52 is electrically connected to the conductive terminal 41. Specifically, the rotating portion 52 is electrically connected to the conductive terminal 41 of the pillow block 40 via the lead 53, and then electrically connected to the control component 21. Therefore, the control component 21 and the electrical module 31 are electrically connected to the electric control installation platform 900 via the conductive slip ring 50 and the conductive terminal 41, so that the power supply current can be output to the electric control installation platform 900 through the conductive terminal 41, avoiding the need for the electric control installation platform 900 to be equipped with a separate battery, which is conducive to simplifying the structure of the electric control installation platform 900. At the same time, the control component 21 and the electrical module 31 form a wired power supply and signal connection with the electronically controlled mounting platform 900 through the conductive terminal 41, so that the motion coordination signal has high stability when transmitted between the electrical module 31 and the electronically controlled mounting platform 900, thereby avoiding the lack of precise synchronization control between different actions due to signal delay in wireless connection (such as Bluetooth connection), and ensuring the user experience of the photographic slide device 100.

[0045] Specifically, the motion coordination signal can be transmitted from the electrical module 31 to the electronically controlled mounting platform 900, or from the electronically controlled mounting platform 900 to the electrical module 31. The motion coordination signal is used to synchronize the translation and rotation of the pillow block 40 with the motion pattern controlled by the electronically controlled mounting platform 900.

[0046] In some embodiments, at least one interface end of the conductive slip ring 50 is in the form of a lead. Specifically, the conductive slip ring 50 is electrically connected to the conductive terminal 41 or the electrical module 31 via the lead 53. Figure 8 As shown, the rotating portion 52 of the conductive slip ring 50 includes a lead 53 and is electrically connected to the conductive terminal 41 via the lead 53. In some embodiments, the fixed portion 51 of the conductive slip ring 50 includes a lead 53 and is electrically connected to the electrical module 31 via the lead 53.

[0047] Specifically, the control assembly 21 can be connected to an external power source to provide power to the electrical module 31 and the electrical control mounting platform 900, allowing the electrical module 31 and the electrical control mounting platform 900 to operate normally. The control assembly 21 can also include a built-in battery, particularly a rechargeable battery, to meet the power supply requirements while achieving portability.

[0048] In some embodiments, the control assembly 21 can also be used to control the linear movement of the slide 30 relative to the base 20. In some embodiments, the control assembly 21 can also send motion coordination signals to the electrical module 31 and the electrical control mounting platform 900. The electrical module 31 and the electrical control mounting platform 900 can provide feedback to the control assembly 21 on the execution result signals.

[0049] In some embodiments, combined Figure 1 and Figure 2 As shown, the base 20 is mounted with a guide rod 22. A slide 30 is slidably mounted on the outer periphery of the guide rod 22, so that the guide rod 22 guides the sliding direction of the slide 30 relative to the base 20. In some embodiments, two guide rods 22 are mounted parallel to the base 20. Furthermore, the slide 30 is simultaneously restrained by the two guide rods 22, with the center of the slide 30 located between the two guide rods 22.

[0050] Combine Figures 5 to 7As shown, the pillow block 40 includes a cover 42 rotatably mounted relative to the slide 30 and an insulating member 46 mounted on the cover 42. A plurality of conductive terminals 41 are inserted into the insulating member 46 at intervals. Specifically, the plurality of conductive terminals 41 are fixedly inserted into the insulating member 46 at intervals, thereby maintaining a stable position between the conductive terminals 41. Since the insulating member 46 is insulating, short circuits of the conductive terminals 41 are avoided. Furthermore, the insulating member 46 and the plurality of conductive terminals 41 can form a pre-assembled body. When the insulating member 46 is mounted on the cover 42, the plurality of conductive terminals 41 are simultaneously mounted on the cover 42, thereby improving the installation efficiency of the conductive terminals 41.

[0051] In some other embodiments, when the cover 42 is made of insulating material, the conductive terminals 41 may also be directly mounted on the cover 42 .

[0052] In some embodiments, combined Figure 6 and Figure 7 As shown, the cover 42 is formed with a slot 421, and the insulating member 46 is installed in the slot 421, so that the outer surface of the insulating member 46 coincides with or is slightly spaced from a portion of the surface of the cover 42. At the same time, the conductive terminal 41 can extend through the slot 421 to the inner side of the cover 42.

[0053] In some embodiments, the insulating member 46 is at least partially exposed from the cover 42 , so that after the electrical control mounting platform 900 is mounted on the pillow block 40 , the outer surface of the insulating member 46 can face the distribution area of ​​the contact terminals 901 of the electrical control mounting platform 900 .

[0054] In some embodiments, combined Figure 2 As shown, the outer end surface of the conductive terminal 41 is flush with the outer surface of the insulating member 46, thereby maintaining the outer surface of the insulating member 46 flat. When the contact terminal 901 of the electric control mounting platform 900 adopts an elastic ejector structure, the conductive terminal 41 is prevented from causing sliding obstruction to the contact terminal 901 of the electric control mounting platform 900.

[0055] In some embodiments, combined Figure 2 As shown, the insulating member 46 is provided with a raised portion 461. The raised portion 461 protrudes relative to the outer surface of the insulating member 46 and is disposed between the outer end surfaces of two adjacent conductive terminals 41. Specifically, the raised portion 461 maintains a distance between other external metal components and the outer surface of the insulating member 46, preventing external metal components from simultaneously making conductive contact with the outer end surfaces of both conductive terminals 41, thereby preventing a short circuit between two conductive terminals 41 with a potential difference. Specifically, the intended use of the conductive terminals 41 can determine whether a potential difference exists between the conductive terminals 41. When arranging the conductive terminals 41, two conductive terminals 41 with a potential difference can be positioned on either side of the raised portion 461.

[0056] In some embodiments, combined Figure 5 As shown, the face cover 42 is connected to two oppositely arranged limit blocks 422. An orientation groove 423 is formed between the two limit blocks 422. Specifically, the electric control installation platform 900 is partially accommodated in the orientation groove 423. Under the limitation of the limit blocks 422, the electric control installation platform 900 can be slidably arranged in the orientation groove 423. Specifically, the orientation groove 423 is close to a dovetail groove in shape. A structure close to a dovetail block is formed on the electric control installation platform 900 to cooperate with the orientation groove 423. Specifically, the extension direction of the convex portion 461 corresponds to the sliding direction of the electric control installation platform 900 in the orientation groove 423.

[0057] In some embodiments, combined Figure 5 and Figure 6 As shown, the cover 42 has opposing first and second ends 424, 425. The first end 424 is used to allow the electric control mounting platform 900 to enter the orientation slot 423. The outer surface of the insulating member 46 includes adjacent mating surfaces 462 and a transition slope 463. The mating surface 462 is positioned to protrude relative to the bottom surface of the orientation slot 423. The conductive terminals 41 are located on the mating surface 462. The transition slope 463 is positioned relative to the mating surface 462, closer to the first end 424 of the cover 42. The transition slope 463 is inclined toward the bottom surface of the orientation slot 423, extending from the second end 425 toward the first end 424. Specifically, if the contact terminals 901 of the electric control mounting platform 900 utilize an elastic ejector pin structure, after the electric control mounting platform 900 slides from the first end 424 into the orientation slot 423, it then slides in a direction from the first end 424 to the second end 425, with the contact terminals 901 first contacting the transition slope 463. The transition slope 463 gradually compresses the contact terminal 901, preventing the end of the contact terminal 901 from being stuck during sliding. Because the mating surface 462 is raised relative to the bottom surface of the orientation slot 423 and the outer end surface of the conductive terminal 41 is flush with the mating surface 462, when the contact terminal 901 contacts the conductive terminal 41, the contact terminal 901 of the electrical control mounting platform 900 remains in a compressed state, thereby maintaining close contact between the contact terminal 901 and the conductive terminal 41 and improving the stability of the electrical contact.

[0058] In some embodiments, the distance between the insulating member 46 and the second end 425 is smaller than the distance between the insulating member 46 and the first end 424 .

[0059] In some embodiments, combined Figure 5 and Figure 7As shown, the cover 42 is connected to a positioning assembly that is used to restrict the electrical control mounting platform 900 from exiting the orientation slot 423, thereby confining the electrical control mounting platform 900 on the pillow block 40. In this fixed position, the contact terminals 901 of the electrical control mounting platform 900 precisely correspond in position with the conductive terminals 41 on the cover 42. In some embodiments, the positioning assembly includes a sliding pin 426. In the reset position, the sliding pin 426 can prevent the electrical control mounting platform 900 from sliding toward the first section of the cover 42. In the unlocked position, the sliding pin 426 releases the restraint on the electrical control mounting platform 900.

[0060] In some embodiments, combined Figure 4 and Figure 9 As shown, the slide 30 is mounted with a rotary drive 33. The rotary drive 33 is used to drive the axial platform 40 in circumferential rotation. Specifically, the rotary drive 33 drives the axial platform 40 in circumferential rotation under the control of an electrical module 31. The electrical module 31 may be a circuit capable of controlling the rotary drive 33 and electrically cooperating with the control assembly 21.

[0061] In some embodiments, combined Figure 6 and Figure 7 As shown, the pillow block 40 also includes a main shaft body 43. The main shaft body 43 includes a shaft barrel portion 431 rotatably received within the slide 30 and a collar portion 432 connected to the shaft barrel portion 431. The face cover 42 is connected to the collar portion 432. Specifically, the shaft barrel portion 431 forms a rotational fit with the slide 30, and the rotating drive member 33 transmits a driving force to the shaft barrel portion 431, causing the pillow block 40 to rotate relative to the slide 30. The outer diameter of the collar portion 432 is larger than the outer diameter of the shaft barrel portion 431. Specifically, the shaft barrel portion 431 is hollow.

[0062] Combine Figure 6 and Figure 7 As shown, in some embodiments, the slide 30 is further mounted with a first radial bearing 281, which is disposed on the outer circumference of the shaft cylinder portion 431 and the inner circumference of the slide 30. Specifically, the presence of the first radial bearing 281 on the outer circumference of the shaft cylinder portion 431 and the slide 30 prevents direct friction between the shaft cylinder portion 431 and the slide 30, ensuring smooth rotation of the main shaft 43 and facilitating improved service life of the main shaft 43 and the slide 30. In some embodiments, the first radial bearing 281 is a deep groove ball bearing.

[0063] In some embodiments, combined Figure 6 and Figure 7As shown, the photographic slide 30 further includes an axial bearing member 35 disposed on the outer periphery of the shaft tube portion 431 and between the underside of the collar portion 432 and the slide 30. Specifically, the gravity of the electronically controlled mounting platform 900 is applied to the collar portion 432, which is located above the slide 30. Because the axial bearing member 35 is disposed between the underside of the collar portion 432 and the slide 30, direct friction between the collar portion 432 and the upper surface of the slide 30 is avoided, ensuring smooth rotation of the main shaft 43 and facilitating the improvement of the service life of the main shaft 43 and the slide 30. In some embodiments, the axial bearing member 35 is a thrust bearing.

[0064] In some embodiments, combined Figure 6 and Figure 8 As shown, the rotating portion 52 is fixedly disposed within the shaft cylinder portion 431, and the outer diameter of the rotating portion 52 corresponds to the inner diameter of the shaft cylinder portion 431. Specifically, by accommodating the rotating portion 52 within the shaft cylinder portion 431, the conductive slip ring 50 is prevented from occupying other space within the slide 30. Because the outer diameter of the rotating portion 52 corresponds to the inner diameter of the shaft cylinder portion 431, the change in the axial center position of the conductive slip ring 50 is reduced during the rotation of the main shaft body 43 relative to the slide 30.

[0065] In some embodiments, combined Figure 6 and Figure 7 As shown, the photographic slide device 100 further includes a circuit board 44. Conductive terminals 41 are fixedly connected to the circuit board 44. An interface socket 441 is fixed to the side of the circuit board 44 facing away from the cover 42. The conductive terminals 41 and the interface socket 441 are electrically connected via the circuit board 44. A cable electrically connected to one interface end of the conductive slip ring 50 is mated to the interface socket 441 via a plug, thereby establishing an electrical connection between the interface end of the conductive slip ring 50 and the conductive terminals 41.

[0066] In some embodiments, combined Figure 6 and Figure 7 As shown, the collar portion 432 is provided with a receiving slot 433. The opening of the receiving slot 433 faces the cover 42 and is connected to the inner cavity of the shaft barrel portion 431. This allows the receiving slot 433 to accommodate the interface socket 441 connected to the circuit board 44 and the plug at the end of the cable. Since the receiving slot 433 is connected to the inner cavity of the shaft barrel portion 431, the cable does not need to pass through narrow spaces, which helps improve the assembly efficiency of the camera slide device 100. Specifically, the circuit board 44 is secured to the collar portion 432 via fasteners. Specifically, the conductive terminal 41 is secured to the circuit board 44 by welding.

[0067] In some embodiments, combined Figure 8 and Figure 9As shown, the photographic slide assembly 100 further includes a wear-resistant member 36. The wear-resistant member 36 is fixedly mounted to the slide 30 and slidably sleeved around the outer periphery of the guide rod 22. Specifically, the wear-resistant member 36 moves with the slide 30 relative to the base 20 and is spaced apart between the guide rod 22 and the slide 30, preventing direct contact between the guide rod 22 and the slide 30, thereby protecting the slide 30 or the guide rod 22 from wear. In some embodiments, the wear-resistant member 36 is a bushing. Furthermore, the hardness of the wear-resistant member 36 is lower than that of the guide rod 22, thereby effectively reducing wear on the guide rod 22.

[0068] In some embodiments, the slide 30 is provided with a rod-through hole 37. The guide rod 22 is inserted into the rod-through hole 37. The inner diameter of the rod-through hole 37 is slightly larger than the outer diameter of the guide rod 22. In some embodiments, a wear-resistant member 36 is secured within the rod-through hole 37 by an interference fit. The inner diameter of the wear-resistant member 36 is larger than the outer diameter of the guide rod 22, and the guide rod 22 slides through the wear-resistant member 36. In other embodiments, the wear-resistant member 36 may be fixedly connected to the slide 30 via a flange and screws.

[0069] In some embodiments, combined Figure 6 and Figure 9 As shown, the output shaft of the rotary drive member 33 is connected to the second worm member 331. A transmission fit is formed between the rotary drive member 33 and the second worm member 331, which can drive the second worm member 331 to rotate along its own axis.

[0070] In some embodiments, combined Figure 7 and Figure 9 As shown, a second worm gear 435 is fixedly connected to the outer periphery of the shaft barrel portion 431, and the second worm member 331 meshes with the second worm gear 435. Specifically, when the second worm member 331 meshes with the second worm gear 435, due to the transmission effect of the worm gear, the second worm gear 435, fixedly connected to the shaft barrel portion 431, can drive the main shaft body 43 to rotate relative to the slide 30. Because the electronically controlled mounting platform 900 is mounted on the cover 42 on the main shaft body 43, the angle of the electronically controlled mounting platform 900 relative to the slide 30 can be adjusted by rotating the output shaft of the driving member 33. Therefore, after the position of the slide 30 changes along a linear direction, the angle of the main shaft body 43 can be adjusted by rotating the driving member 33 to ensure that the center of the electronically controlled mounting platform 900's shooting range remains aligned with the target, ensuring effective shooting. Furthermore, under the transmission effect of the worm gear, the rotation speed of the pillow block 40 can be much lower than the rotation speed of the output shaft of the rotary drive member 33, which is conducive to accurately adjusting the angle of the electronically controlled mounting platform 900.

[0071] In some other embodiments, a second worm gear structure is formed on the outer periphery of the main shaft body 43, and the second worm member 331 is engaged with the second worm gear structure. Specifically, when the second worm member 331 is engaged with the second worm gear structure formed on the outer periphery of the main shaft body 43, the second worm member 331 directly drives the main shaft body 43 to rotate relative to the slide 30. In some embodiments, the shaft barrel portion 431 is formed with a plurality of worm gear teeth protruding outwardly on the outer periphery, and the worm gear teeth are engaged with the second worm member 331. In some other embodiments, a groove is provided on the outer side of the shaft barrel portion 431, and the plurality of grooves are distributed along the outer periphery of the shaft barrel portion 431, and the shaft barrel portion 431 is engaged with the second worm member 331 at the position between two adjacent grooves.

[0072] In some embodiments, combined Figure 6 and Figure 7 As shown, the pillow block 40 is connected to a threaded member 45, which is threadedly mounted on the outer circumference of the shaft cylinder portion 431. The second worm gear 435 is also threadedly mounted on the outer circumference of the shaft cylinder portion 431. Specifically, the threaded member 45 and the second worm gear 435 are respectively threadedly mounted on the outer circumference of the shaft cylinder portion 431. By utilizing the threaded member 45 to abut against the second worm gear 435 along the axial direction of the shaft cylinder portion 431, the second worm gear 435 is maintained at a fixed position and angle relative to the pillow block 40, thereby enabling the second worm gear 435 to drive the pillow block 40 to rotate.

[0073] In some embodiments, combined Figure 9 and Figure 10 As shown, the slide 30 is connected to a bracket 38. A slot 381 is provided at one end of the bracket 38, and the slot 381 surrounds the outer circumference of the support bar 23. The elastic spiral conductor 24 is partially embedded in the slot 381. Specifically, by partially embedding the elastic spiral conductor 24 in the slot 381, the bracket 38 limits the elastic spiral conductor 24. When the slide 30 moves relative to the base 20, the portion of the elastic spiral conductor 24 between the bracket 38 and the base 20 can be expanded and contracted, and the end of the elastic spiral conductor 24 can be prevented from being electrically loosened relative to the slide 30. More specifically, the bracket 38 is connected to the slide 30. In one embodiment, one end of the elastic spiral conductor 24 is embedded in the slot 381, and the other end is fixed to the base 20.

[0074] In some embodiments, combined Figure 11 and Figure 12As shown, the base 20 is equipped with a support bar 23 and an elastic spiral conductor 24. The extension direction of the support bar 23 corresponds to the sliding direction of the slider 30. The elastic spiral conductor 24 is wound around the outer circumference of the support bar 23. The elastic spiral conductor 24 is electrically connected between the control component 21 and the electrical module 31. Specifically, the elastic spiral conductor 24 is retractable. When the position of the slider 30 relative to the base 20 changes, the slider 30 stretches the elastic spiral conductor 24 so that the length of the elastic spiral conductor 24 can adapt to the position change of the slider 30, thereby maintaining an electrical connection between the control component 21 and the electrical module 31 when the slider 30 is in different positions. The extension direction of the support bar 23 is parallel or approximately parallel to the sliding direction of the slider 30. The support bar 23 supports the elastic spiral conductor 24 and prevents it from sagging.

[0075] In one embodiment, the elastic spiral conductor 24 may include a retractable spring and a flexible conductor, with the flexible conductor being spirally attached to the retractable spring, and the flexible conductor and the retractable spring being enclosed within the same insulating sleeve. In another embodiment, the elastic spiral conductor 24 may include an elastic conductor, which is enclosed within the insulating sleeve. Specifically, the elastic conductor has a memory shape, and when the tension acting on the elastic conductor is removed, the elastic conductor can contract to the memory shape. Specifically, the elastic conductor can be an elastically coiled metal wire.

[0076] In some embodiments, the support bar 23 is a nylon rope in a straight state. Further, the two ends of the support bar 23 are respectively fixed to the base 20. In other embodiments, the support bar 23 can also be a metal rod.

[0077] In some embodiments, combined Figures 10 to 12 As shown, the photographic slide device 100 further includes a shift driver 25 and a transmission assembly 26 mounted on the base 20. Specifically, the shift driver 25 drives the slide 30 to slide linearly relative to the base 20 via the transmission assembly 26. The shift driver 25 drives the slide 30 to slide linearly under the control of the control assembly 21. The control assembly 21 can specifically be a circuit or module capable of controlling the shift driver 25 and electrically cooperating with the electrical module 31. In some embodiments, the control assembly 21 includes a display screen to display status information.

[0078] In some embodiments, combined Figure 11 and Figure 12As shown, the base 20 is connected to a first worm member 27 and a transmission shaft 28. The first worm member 27 is rotatably mounted on the base 20. The transmission shaft 28 is rotatably mounted on the base 20. In some embodiments, a first worm gear 29 is fixedly connected to the outer periphery of the transmission shaft 28, and the first worm member 27 meshes with the first worm gear 29. In other embodiments, a first worm gear structure is formed on the outer periphery of the transmission shaft 28, and the first worm member 27 meshes with the first worm gear structure. The output shaft of the displacement drive 25 is connected to the first worm member 27. The transmission assembly 26 is connected between the transmission shaft 28 and the slide 30. The transmission shaft 28 forms a transmission connection with the slide 30 through the transmission assembly 26. When the transmission shaft 28 rotates, it can cause the slide 30 to slide relative to the base 20. Specifically, when the slide 30 moves relative to the base 20, the slide 30 can drive the electronic control mounting platform 900 to move linearly.

[0079] Specifically, the slide 30 is guided and can slide within a straight line relative to the base 20. The output shaft of the shift driver 25 can drive the first worm 27 to rotate, causing the first worm 27 to rotate about its own axis. When the first worm 27 is engaged with the first worm wheel 29, the first worm wheel 29 can drive the drive shaft 28 to rotate relative to the base 20. Because the drive shaft 28 forms a transmission connection with the slide 30 through the transmission assembly 26, the rotation of the drive shaft 28 causes the slide 30 to slide relative to the base 20, thereby enabling the shift driver 25 to adjust the position of the slide 30. Due to the worm-gear transmission mechanism, the speed of the drive shaft 28 is much lower than that of the first worm 27, allowing for precise control of the movement speed and position of the slide 30, thereby improving the accuracy of the position control of the electronically controlled mounting platform 900. In some embodiments, the drive shaft 28 has a plurality of worm gear teeth formed on its outer circumference, which mesh with the first worm 27.

[0080] In some embodiments, combined Figures 10 to 12As shown, the transmission assembly 26 includes a driving pulley 261, a driven pulley 262, and a synchronous belt 263. The driving pulley 261 and the driven pulley 262 are rotatably mounted on the base 20. The transmission shaft 28 forms a transmission connection with the driving pulley 261. The synchronous belt 263 is extended around the outer periphery of the driving pulley 261 and the driven pulley 262. The slide 30 is connected to the synchronous belt 263. Specifically, the slide 30 is connected to a small section of the synchronous belt 263. When the driving pulley 261 rotates and the small section of the synchronous belt 263 moves linearly, the slide 30 moves linearly under the traction of the synchronous belt 263. In some embodiments, the slide 30 is connected to a clamping block 32, which is fixedly mounted to a section of the synchronous belt 263, so that the synchronous belt 263 can drive the slide 30 to move. More specifically, there can be one or more driven pulleys 262. In other embodiments, the transmission assembly 26 includes a screw that is threadedly engaged with the slide 30. The transmission shaft 28 can drive the screw to rotate. When the screw rotates, it drives the slide 30 to move along a straight line.

[0081] Further, combined with Figure 12 As shown, the base 20 is mounted with a second radial bearing 34. One end of the transmission shaft 28 is inserted into the second radial bearing 34. The other end of the transmission shaft 28 is connected to the driving wheel 261.

[0082] In some embodiments, the displacement driver 25 is a stepper motor or a servo motor. In some embodiments, the rotation driver 33 is a stepper motor or a servo motor.
