Abstract

This invention provides a slide rail device for photography that can reduce wear and noise. [Solution] A guide rod 22 is attached to the base 20. The slide sheet 30 is slidably fitted to the outer circumference of the guide rod. The wear-resistant member is fixedly attached to the slide sheet. The wear-resistant member is slidably fitted to the outer circumference of the guide rod and is provided between the guide rod and the slide sheet.

[0005] ,

[0001] The present invention relates to the technical field of imaging equipment, and particularly to a photographing device and its slide rail device for photographing.

Background Art

[0002] A slide rail for photographing is a device used to assist the movement of a camera, an electric control pan-tilt, or other related modules, thereby enabling the camera to take pictures from different positions and meeting the various camera angle requirements of photographers. The slide rail for photographing can not only realize the translational movement of the camera, but also enable the camera to rotate around two different axes simultaneously by cooperating with an electric control pan-tilt. In the prior art, a slide rail for photographing generally includes a base and a slide sheet slidably connected to the base. The slide sheet is used to drive the camera to move relative to the base.

[0003] However, in the process of using the slide rail for photographing, the slide sheet often slides repeatedly relative to the base, and there is sliding friction at the sliding contact part between the slide sheet and the base. Since there may be burrs or non-flat areas on the contact surface of the slide sheet, when the contact surface of the slide sheet repeatedly slides in contact with the base, the base is likely to be severely worn or a large amount of noise is likely to occur.

[0037] The technical proposal provided by the embodiments of this application is described below with reference to the attached drawings.

[0038] Figures 1 to 12 show a photographic slide rail device 100 according to at least one embodiment of the present invention. As shown in Figure 1, the present application provides a photographic slide rail device 100 to which an electrically controlled mounting platform 900 is attached and connected. The photographic slide rail device 100 can drive the electrically controlled mounting platform 900 to move along a straight path and rotate about a first axis.

[0039] As shown in Figures 4 and 5, the electrically controlled mounting platform 900 is used to mount or connect the camera and is equipped with an electric control device. The electrically controlled mounting platform 900 may also be an electrically controlled pan-tilt for the camera and is used to rotate the camera around one or more axes different from the first axis. The electrically controlled mounting platform 900 may also be a stabilizer and is used to eliminate camera shake.

[0040] To make it clear, the photographic slide rail device 100 is also used to attach a quick-release plate, which is used to directly secure a camera or other photographic equipment.

[0041] Specifically, as shown in Figures 5 to 7, the photographic slide rail device 100 comprises a base 20, a control component 21, a slide sheet 30, a pivot 40, and conductive slip rings 50. The control component 21 is mounted inside the base 20. The slide sheet 30 is slidably mounted on the base 20, and an electrical module 31 is fixed inside the slide sheet 30, which is electrically connected to the control component 21. The pivot 40 is rotatably mounted on the slide sheet 30, and the pivot 40 is used to connect the camera's electrical control mounting platform 900, and the pivot 40 is provided with conductive terminals 41 for conductive contact with the electrical control mounting platform 900. The conductive slip rings 50 are electrically connected to the electrical module 31 and the conductive terminals 41 of the pivot 40, respectively.

[0042] Specifically, the electrical control installation platform 900 has a conductive terminal 41 and a contact terminal 901 for electrical connection. After the electrical control installation platform 900 is attached to the axle head 40 of the photographic slide rail device 100 of the present invention, the contact terminal 901 of the electrical control installation platform 900 and the electrical module 31 are electrically connected via the conductive terminal 41 and conductive slip ring 50 of the axle head 40, thereby achieving an electrical connection.

[0043] The conductive slip ring 50 comprises a rotating portion 52 and a fixed portion 51. The rotating portion 52 is rotatable 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 shaft 40 and rotates together with the shaft 40. The fixed portion 51 is fixedly connected to the slide sheet 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 shaft 40 via lead wires 53, and thereby electrically connected to the control component 21. Therefore, the control component 21 and the electrical module 31 are electrically connected to the electrical control installation platform 900 via the conductive slip ring 50 and the conductive terminal 41, thereby being able to output power supply current to the electrical control installation platform 900 via the conductive terminal 41, eliminating the need for the electrical control installation platform 900 to have a separate battery, and contributing to the simplification of the structure of the electrical 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 electrical control installation platform 900 via the conductive terminal 41, thereby increasing the stability of the transmission of motion coordination signals between the electrical module 31 and the electrical control installation platform 900, and thereby avoiding insufficient accuracy of synchronous control between different operations due to signal delays caused by wireless connections (e.g., Bluetooth connections), and ensuring a good user experience with the shooting slide rail device 100.

[0045] Specifically, the motion coordination signal may be transmitted from the electrical module 31 to the electrical control installation platform 900, or from the electrical control installation platform 900 to the electrical module 31. The motion coordination signal is used to maintain a constant synchronization relationship between the translational movement and rotation of the axle head 40 and the motion modes controlled by the electrical control installation platform 900.

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

[0047] Specifically, the control component 21 can be connected to an external power supply and provides power to the electrical module 31 and the electrical control installation platform 900, enabling them to operate normally. The control component 21 may also be equipped with a built-in battery, particularly a rechargeable battery, to meet the power supply requirements for shooting while simultaneously achieving portability.

[0048] In some embodiments, the control component 21 is also used to control the linear movement of the slide sheet 30 relative to the base 20. In some embodiments, the control component 21 can also transmit motion coordination signals to the electrical module 31 and the electrical control installation platform 900. The electrical module 31 and the electrical control installation platform 900 can feed back execution result signals to the control component 21.

[0049] In some embodiments, guide rods 22 are attached to the base 20, as shown in Figures 1 and 2. The slide sheet 30 is slidably fitted in a sleeve-like manner to the outer circumference of the guide rods 22, thereby guiding the slide sheet 30 in the sliding direction relative to the base 20. In some embodiments, two guide rods 22 are mounted on the base 20 parallel to each other. Furthermore, the slide sheet 30 is simultaneously restricted by the two guide rods 22, and the center of the slide sheet 30 is located between the two guide rods 22.

[0050] As shown in Figures 5 to 7, the shaft base 40 includes a face cover 42 rotatably mounted on the slide sheet 30, and an insulating member 46 attached to the face cover 42. Multiple conductive terminals 41 are inserted into the insulating member 46 at intervals. Specifically, the multiple conductive terminals 41 are fixedly inserted into the insulating member 46 at intervals, thereby maintaining a stable position between each conductive terminal 41. Since the insulating member 46 has insulating properties, it prevents short circuits of the conductive terminals 41. At the same time, the insulating member 46 and the multiple conductive terminals 41 can form a pre-assembled unit, and when attaching the insulating member 46 to the face cover 42, the multiple conductive terminals 41 can be attached to the face cover 42 simultaneously, thereby improving the efficiency of attaching the conductive terminals 41.

[0051] In some other embodiments, if the face cover 42 is made of an insulating material, the conductive terminal 41 may be directly attached to the face cover 42.

[0052] In some embodiments, as shown in Figures 6 and 7, a groove 421 is formed in the face cover 42, and an insulating member 46 is mounted within the groove 421, so that the outer surface of the insulating member 46 overlaps with a portion of the surface of the face cover 42 or is separated by a very small distance. At the same time, the conductive terminal 41 can extend into the inside of the face cover 42 through the groove 421.

[0053] In some embodiments, the insulating member 46 is at least partially exposed from the face cover 42 so that, after the electrical control installation platform 900 is mounted to the shaft base 40, the outer surface of the insulating member 46 faces the distribution area of ​​the contact terminals 901 of the electrical control installation platform 900.

[0054] In some embodiments, as shown in Figure 2, the outer end surface of the conductive terminal 41 is coplanar with the outer surface of the insulating member 46, thereby keeping the outer surface of the insulating member 46 flat. When the contact terminals 901 of the electrical control installation platform 900 employ an elastic pogo pin structure, the conductive terminal 41 avoids causing snagging on the contact terminals 901 of the electrical control installation platform 900 during sliding.

[0055] In some embodiments, as shown in Figure 2, the insulating member 46 is provided with a columnar projection 461. The columnar projection 461 protrudes from the outer surface of the insulating member 46 and is provided between the outer end faces of two adjacent conductive terminals 41. Specifically, the columnar projection 461 can maintain a distance between other external metal parts and the outer surface of the insulating member 46, preventing the external metal parts from simultaneously making conductive contact with the outer end faces of the two conductive terminals 41 and preventing a short circuit from occurring between two conductive terminals 41 with a potential difference. Specifically, depending on the predetermined application of the conductive terminals 41, it can be determined whether a potential difference exists between the conductive terminals 41, and when arranging the conductive terminals 41, two conductive terminals 41 with a potential difference can be provided on both sides of the columnar projection 461.

[0056] In some embodiments, as shown in Figure 5, the face cover 42 is connected to two opposing position-limiting blocks 422. A directional groove 423 is formed between the two position-limiting blocks 422. Specifically, the electrical control installation platform 900 is partially housed in the directional groove 423. Under the constraints of the position-limiting blocks 422, the electrical control installation platform 900 is slidably installed within the directional groove 423. Specifically, the directional groove 423 has a shape similar to a dovetail groove. A structure similar to a dovetail block is formed on the electrical control installation platform 900 to align with the dovetail groove. Specifically, the direction of extension of the columnar projection 461 corresponds to the direction in which the electrical control installation platform 900 can slide within the directional groove 423.

[0057] In some embodiments, as shown in Figures 5 and 6, the face cover 42 is provided with opposing first end 424 and second end 425. The first end 424 is used for the electrical control installation platform 900 to enter the directional groove 423. The outer surface of the insulating member 46 is provided with adjacent mating surfaces 462 and transition inclined surfaces 463, the mating surfaces 462 being convex with respect to the bottom surface of the directional groove 423. The conductive terminals 41 are distributed on the mating surfaces 462. The transition inclined surfaces 463 are closer to the first end 424 of the face cover 42 relative to the mating surfaces 462. Along the direction from the second end 425 to the first end 424, the transition inclined surfaces 463 are inclined in a direction toward the bottom surface of the directional groove 423. Specifically, when the contact terminal 901 of the electrical control installation platform 900 employs an elastic pogo pin structure, after the electrical control installation platform 900 slides into the directional groove 423 from the first end 424, the electrical control installation platform 900 slides along the direction from the first end 424 to the second end 425, and the contact terminal 901 first comes into contact with the transition inclined surface 463. The transition inclined surface 463 gradually compresses the contact terminal 901, preventing the end of the contact terminal 901 from getting caught during sliding. The mating surface 462 is provided in a convex shape with respect to the bottom surface of the directional groove 423, and the outer end surface of the conductive terminal 41 is on the same plane as the mating surface 462. Therefore, when the contact terminal 901 comes into contact with the conductive terminal 41, the contact terminal 901 of the electrical control installation platform 900 is kept 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, a positioning component is connected to the face cover 42, as shown in Figures 5 and 7. The positioning component restricts the electrical control mounting platform 900 from disengaging from the directional groove 423, thereby confining the electrical control mounting platform 900 to the axle base 40. In this fixed position, the multiple contact terminals 901 of the electrical control mounting platform 900 correspond positionally precisely to the multiple conductive terminals 41 on the face cover 42. In some embodiments, the positioning component includes a slide pin 426. In the return position, the slide pin 426 can prevent the electrical control mounting platform 900 from sliding toward the first end of the face cover 42. In the unlocked position, the restriction of the electrical control mounting platform 900 by the slide pin 426 is released.

[0060] In some embodiments, as shown in Figures 4 and 9, a rotary drive member 33 is attached to the slide sheet 30. The rotary drive member 33 is used to rotate the axle head 40 along the circumferential direction. Specifically, the rotary drive member 33 rotates the axle head 40 along the circumferential direction under the control of an electrical module 31. The electrical module 31 may specifically be a circuit that can control the rotary drive member 33 and form an electrical connection with a control component 21.

[0061] In some embodiments, as shown in Figures 6 and 7, the headstock 40 further includes a spindle body 43. The spindle body 43 includes a shaft cylinder portion 431 rotatably housed within the slide sheet 30 and a shaft ring portion 432 connected to the shaft cylinder portion 431. A face cover 42 is connected to the shaft ring portion 432. Specifically, the shaft cylinder portion 431 forms rotational cooperation with the slide sheet 30, and a rotational drive member 33 transmits driving force to the shaft cylinder portion 431, causing the headstock 40 to rotate relative to the slide sheet 30. The outer diameter of the shaft ring portion 432 is larger than the outer diameter of the shaft cylinder portion 431. Specifically, the shaft cylinder portion 431 is hollow.

[0062] As shown in Figures 6 and 7, in some embodiments, a first radial bearing member 281 is further attached to the slide sheet 30, and the first radial bearing member 281 is provided on the outer circumference of the shaft cylinder portion 431 and on the inner circumference of the slide sheet 30. Specifically, since the first radial bearing member 281 is provided between the outer circumference of the shaft cylinder portion 431 and the slide sheet 30, direct friction between the shaft cylinder portion 431 and the slide sheet 30 is avoided, ensuring smooth rotation of the main shaft body 43 and is advantageous in improving the service life of the main shaft body 43 and the slide sheet 30. In some embodiments, the first radial bearing member 281 is a deep groove ball bearing.

[0063] In some embodiments, as shown in Figures 6 and 7, the slide sheet 30 further includes an axial bearing member 35, which is provided on the outer circumference of the shaft cylinder portion 431 and is located between the lower side of the shaft ring portion 432 and the slide sheet 30. Specifically, gravity from the electronically controlled installation platform 900 is applied to the shaft ring portion 432, and the shaft ring portion 432 is located above the slide sheet 30. Because the axial bearing member 35 is provided between the lower side of the shaft ring portion 432 and the slide sheet 30, direct friction between the shaft ring portion 432 and the upper surface of the slide sheet 30 is avoided, ensuring smooth rotation of the main shaft body 43 and contributing to improved service life of the main shaft body 43 and the slide sheet 30. In some embodiments, the axial bearing member 35 is a thrust bearing.

[0064] In some embodiments, as shown in Figures 6 and 8, the rotating part 52 is fixedly provided within the shaft cylinder 431, and the outer diameter of the rotating part 52 corresponds to the inner diameter of the shaft cylinder 431. Specifically, by housing the rotating part 52 within the shaft cylinder 431, it is possible to avoid the conductive slip ring 50 occupying other space within the slide sheet 30. Because the outer diameter of the rotating part 52 corresponds to the inner diameter of the shaft cylinder 431, the change in the axial position of the conductive slip ring 50 can be reduced during the rotation of the main shaft 43 relative to the slide sheet 30.

[0065] In some embodiments, as shown in Figures 6 and 7, the photographic slide rail 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 circuit board 44 on the side opposite the face cover 42. An electrical connection is formed between the conductive terminals 41 and the interface socket 441 via the circuit board 44. A cable electrically connected to one interface end of the conductive slip ring 50 is connected to the interface socket 441 via a plug, thereby forming an electrical connection between one interface end of the conductive slip ring 50 and the conductive terminals 41.

[0066] In some embodiments, as shown in Figures 6 and 7, a housing groove 433 is provided in the shaft ring portion 432. The opening of the housing groove 433 faces the direction of the face cover 42, and the housing groove 433 communicates with the lumen of the shaft cylinder portion 431, thereby allowing the housing groove 433 to accommodate the interface socket 441 connected to the circuit board 44 and the plug at the end of the cable. Because the housing groove 433 communicates with the lumen of the shaft cylinder portion 431, the cable does not need to pass through a narrow space, which is advantageous in improving the assembly efficiency of the photographic slide rail device 100. Specifically, the circuit board 44 is fixed to the shaft ring portion 432 via fasteners. Specifically, the conductive terminals 41 are soldered to the circuit board 44.

[0067] In some embodiments, as shown in Figures 8 and 9, the photographic slide rail device 100 further includes a wear-resistant member 36. The wear-resistant member 36 is fixedly attached to the slide sheet 30 and is slidably fitted to the outer circumference of the guide rod 22. Specifically, the wear-resistant member 36 moves with the slide sheet 30 relative to the base 20 and is provided with a gap between the guide rod 22 and the slide sheet 30 to avoid direct contact between the guide rod 22 and the slide sheet 30, thereby preventing wear on the slide sheet 30 or the guide rod 22. 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 sheet 30 is provided with a rod through hole 37. The guide rod 22 is provided passing through 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 fixed within the rod through hole 37 by 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 is provided slidingly through the wear-resistant member 36. In some other embodiments, the wear-resistant member 36 may be fixedly connected to the slide sheet 30 via flanges and screws.

[0069] In some embodiments, as shown in Figures 6 and 9, a second worm member 331 is connected to the output shaft of the rotary drive member 33. A transmission cooperation is formed between the rotary drive member 33 and the second worm member 331, which allows the second worm member 331 to rotate around its own axis.

[0070] In some embodiments, as shown in Figures 7 and 9, a second worm gear member 435 is fixedly connected to the outer circumference of the shaft cylinder portion 431, and the second worm member 331 meshes with the second worm gear member 435. Specifically, when the second worm member 331 and the second worm gear member 435 mesh, under the transmission action of a worm and worm gear type, the second worm gear member 435 is fixedly connected to the shaft cylinder portion 431, and therefore the second worm gear member 435 can drive the main shaft body 43 to rotate relative to the slide sheet 30. Since the electronically controlled mounting platform 900 is mounted on the face cover 42 on the main shaft body 43, the angle of the electronically controlled mounting platform 900 relative to the slide sheet 30 can be adjusted by rotating the output shaft of the rotary drive member 33. Therefore, after the linear position of the slide sheet 30 changes, the angle adjustment of the main shaft body 43 by the rotary drive member 33 can keep the center of the shooting range of the electronically controlled mounting platform 900 aligned with the target, thereby ensuring the shooting effect. Furthermore, under the transmission operation of worm and worm gear types, the rotational speed of the shaft head 40 can be made much lower than the rotational speed of the output shaft of the rotary drive member 33, thereby advantageous for precisely 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 circumference of the main shaft 43, and the second worm member 331 meshes with the formed second worm gear structure. Specifically, when the second worm member 331 meshes with the second worm gear structure formed on the outer circumference of the main shaft 43, the second worm member 331 directly drives the main shaft 43 to rotate relative to the slide seat 30. In some embodiments, the shaft cylinder portion 431 has a plurality of worm gear teeth that protrude outward on the outer circumference, and the worm gear teeth mesh and fit with the second worm member 331. In some other embodiments, grooves are provided on the outside of the shaft cylinder portion 431, and a plurality of grooves are distributed in the direction of the outer circumference of the shaft cylinder portion 431, and the portion between two adjacent grooves of the shaft cylinder portion 431 meshes and fits with the second worm member 331.

[0072] In some embodiments, as shown in Figures 6 and 7, a threaded member 45 is connected to the shaft head 40, the threaded member 45 is screw-fitted to the outer circumference of the shaft cylinder portion 431, and the second worm gear member 435 is screw-fitted to the outer circumference of the shaft cylinder portion 431. Specifically, the threaded member 45 and the second worm gear member 435 are screw-fitted to the outer circumference of the shaft cylinder portion 431, and by using the threaded member 45 to bring the second worm gear member 435 into contact with the shaft cylinder portion 431 along the axial direction, the second worm gear member 435 can be kept in a fixed position and angle relative to the shaft head 40, and therefore the second worm gear member 435 can drive the shaft head 40 to rotate.

[0073] In some embodiments, as shown in Figures 9 and 10, a bracket 38 is connected to the slide sheet 30. A locking groove 381 is provided at one end of the bracket 38, and the locking groove 381 surrounds the outer circumference of the support bar 23. The elastic helical conductor 24 is partially fitted into the locking groove 381. Specifically, by partially fitting the elastic helical conductor 24 into the locking groove 381, the bracket 38 performs a position-limiting effect on the elastic helical conductor 24. When the slide sheet 30 moves relative to the base 20, the elastic helical conductor 24 can expand and contract in the portion between the bracket 38 and the base 20, and the end of the elastic helical conductor 24 is prevented from electrically loosening relative to the slide sheet 30. More specifically, the bracket 38 is connected to the slide sheet 30. In one embodiment, one end of the elastic helical conductor 24 is fitted into the locking groove 381, and the other end is fixed to the base 20.

[0074] In some embodiments, as shown in Figures 11 and 12, a support bar 23 and an elastic helical conductor 24 are attached to the base 20. The direction of extension of the support bar 23 corresponds to the sliding direction of the slide sheet 30. The elastic helical conductor 24 is wrapped around the outer circumference of the support bar 23. The elastic helical conductor 24 is electrically connected between the control component 21 and the electrical module 31. Specifically, the elastic helical conductor 24 is expandable and contractible, and as the position of the slide sheet 30 relative to the base 20 changes, the slide sheet 30 pulls on the elastic helical conductor 24, allowing the length of the elastic helical conductor 24 to change in response to the change in the position of the slide sheet 30, thereby maintaining the electrical connection between the control component 21 and the electrical module 31 at all times when the slide sheet 30 is in a different position. The direction of extension of the support bar 23 is parallel or nearly parallel to the sliding direction of the slide sheet 30. The support bar 23 provides support for the elastic helical conductor 24, preventing it from sagging.

[0075] In one embodiment, the elastic helical conductor 24 may include a retractable spring and a flexible conductor, the flexible conductor being helically attached to the retractable spring, and the flexible conductor and the retractable spring being enclosed within the same insulating tube. In another embodiment, the elastic helical conductor 24 may include an elastic conductor, the elastic conductor being enclosed within the insulating tube. Specifically, the elastic conductor has shape memory, and when the attractive force acting on the elastic conductor is removed, the elastic conductor can contract into a shape-memory form. Specifically, the elastic conductor may be an elastic helical metal wire.

[0076] In some embodiments, the support bar 23 is a taut nylon rope. Furthermore, both ends of the support bar 23 are fixed to the base 20. In some other embodiments, the support bar 23 may be a metal rod.

[0077] In some embodiments, as shown in Figures 10 to 12, the photographic slide rail device 100 further includes a movable drive member 25 and a transmission component 26 mounted on a base 20. Specifically, the movable drive member 25 drives the slide sheet 30 via the transmission component 26, causing it to slide linearly relative to the base 20. The movable drive member 25 slides the slide sheet 30 linearly under the control of a control component 21. The control component 21 may specifically be a circuit or module that controls the movable drive member 25 and can be electrically coupled with an electrical module 31. In some embodiments, the control component 21 includes a display screen for displaying status information.

[0078] In some embodiments, as shown in Figures 11 and 12, a first worm member 27 and a transmission shaft rod 28 are connected to the base 20. The first worm member 27 is rotatably mounted to the base 20. The transmission shaft rod 28 is rotatably mounted to the base 20. In some embodiments, a first worm gear member 29 is fixedly connected to the outer circumference of the transmission shaft rod 28, and the first worm member 27 meshes with the first worm gear member 29. In some other embodiments, a first worm gear structure is formed on the outer circumference of the transmission shaft rod 28, and the first worm member 27 meshes with the first worm gear structure. The output shaft of the moving drive member 25 is connected to the first worm member 27. A transmission component 26 is connected between the transmission shaft rod 28 and the slide seat 30. The transmission shaft rod 28 forms a transmission cooperation with the slide seat 30 via the transmission component 26, and the transmission shaft rod 28 can cause the slide seat 30 to slide relative to the base 20 when rotating. Specifically, when the slide sheet 30 moves relative to the base 20, the slide sheet 30 can be driven by the electronically controlled installation platform 900 to move in a straight line.

[0079] Specifically, the slide sheet 30 is guided and can slide relative to the base 20 within a linear range. The output shaft of the moving drive member 25 can rotate the first worm member 27, causing the first worm member 27 to rotate around its own axis. When the first worm member 27 and the first worm gear member 29 mesh, the first worm gear member 29 can drive the transmission shaft rod 28 to rotate relative to the base 20. Since the transmission shaft rod 28 forms a transmission cooperation with the slide sheet 30 via the transmission component 26, when the transmission shaft rod 28 rotates, the slide sheet 30 can slide relative to the base 20, and thus the moving drive member 25 can adjust the position of the slide sheet 30. Under the transmission action of the worm and worm gear type, the rotational speed of the transmission shaft rod 28 is much lower than the rotational speed of the first worm member 27, thereby allowing for precise control of the moving speed and moving position of the slide sheet 30, which is advantageous for improving the accuracy of position control of the electronically controlled installation platform 900. In some embodiments, the transmission shaft rod 28 has a plurality of worm gear teeth that protrude outward on its outer circumference, and the worm gear teeth mesh and fit with the first worm member 27.

[0080] In some embodiments, as shown in Figures 10 to 12, the transmission component 26 includes a drive wheel 261, a driven wheel 262, and a synchronous belt 263. The drive wheel 261 and the driven wheel 262 are each rotatably mounted to a base 20. A transmission shaft rod 28 forms a transmission cooperation with the drive wheel 261. The synchronous belt 263 is stretched around the outer circumference of the drive wheel 261 and the driven wheel 262. A slide sheet 30 is connected to the synchronous belt 263. Specifically, the slide sheet 30 is connected to a portion of the synchronous belt 263. As the drive wheel 261 rotates and a portion of the synchronous belt 263 moves linearly, the slide sheet 30 moves linearly under the traction of the synchronous belt 263. In some embodiments, a clamp block 32 is connected to the slide sheet 30 and is fixed to a portion of the synchronous belt 263 so that the synchronous belt 263 can drive the slide sheet 30 to move it. More specifically, there may be one or more driven wheels 262. In some other embodiments, the transmission component 26 includes a lead screw, which is screw-fitted to the slide seat 30. A transmission shaft rod 28 can rotate the lead screw. When the lead screw rotates, it drives the slide seat 30 to move linearly.

[0081] Furthermore, as shown in Figure 12, a second radial bearing member 34 is attached to the base 20. One end of the transmission shaft rod 28 is inserted into the second radial bearing member 34. The other end of the transmission shaft rod 28 is connected to the drive wheel 261.

[0082] In some embodiments, the moving drive member 25 is a stepping motor or a servo motor. In some embodiments, the rotating drive member 33 is a stepping motor or a servo motor.
