The axle base is rotatably arranged on the sliding seat and used for connecting an electric control mounting platform of a camera. The axle base is provided with a conductive terminal used for forming conductive contact with the electric control mounting platform.

Description

[0001] This application is a divisional application of utility model patent application No. 202423105971.0, entitled "Photographic Sliding Rail Device", which was filed on December 16, 2024. Technical Field

[0002] This application relates to the field of camera equipment technology, and in particular to a camera slider device. Background Technology

[0003] A camera slider is a device used to assist in moving a camera, electronic pan / tilt head, or other related modules, allowing the camera to shoot from different positions to meet the photographer's requirements for shooting angles. A camera slider not only enables camera panning but also, when used in conjunction with an electronic pan / tilt head, allows the camera to rotate simultaneously around two different axes. In traditional technology, a camera slider generally consists of a base and a slide block slidably connected to the base. The slide block is used to move the camera relative to the base.

[0004] However, during the use of a camera slider, the slider often slides repeatedly relative to the base, resulting in sliding friction at the contact point between the slider and the base. Since the contact surface of the slider may have burrs or uneven areas, the base is prone to significant wear or noise when the slider's contact surface repeatedly slides against the base.

[0007] The aforementioned photographic slide rail device, because the wear-resistant parts move with the slide relative to the base, and the wear-resistant parts are spaced apart between the guide rod and the slide, avoids direct contact between the guide rod and the slide, thereby preventing wear on the slide or guide rod.

[0012] In one embodiment, the wear-resistant component is a bushing; the cross-section of the wear-resistant component is a circumferentially closed annulus, and the cross-section of the guide rod is circular.

[0013] In one embodiment, two wear-resistant components are provided for each guide rod, and the two wear-resistant components are arranged sequentially along the axial direction on the slide block, and the guide rod is slidably passed through the two wear-resistant components in sequence.

[0014] In one embodiment, the hardness of the wear-resistant component is lower than that of the guide rod.

[0015] In one embodiment, a shaft platform for connecting the electrical control mounting platform is further included; the shaft platform is rotatably mounted on the slide and is provided with conductive terminals for forming conductive contact with the electrical control mounting platform.

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

[0034] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0035] Figures 1 to 12 A photographic slide rail device 100 according to at least one embodiment of the present invention is shown. Combined with... Figure 1 As shown, this application provides a camera slide rail device 100 for mounting and connecting an electrically controlled mounting platform 900. The camera slide rail device 100 is capable of driving the electrically controlled mounting platform 900 to move along a straight path and rotate about a first axis.

[0036] Combination Figure 4 and Figure 5 As shown, the electrically controlled mounting platform 900 is used to mount or connect a camera and includes an electric control device. The electrically controlled mounting platform 900 can be a camera gimbal for driving 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 for eliminating camera shake.

[0037] Understandably, the camera slide rail device 100 is also used to mount a quick-release plate, which is used to directly fix a camera or other photographic equipment.

[0038] Specifically, in combination Figures 5 to 7 As shown, the camera slide rail device 100 includes: a base 20, a control component 21, a slide 30, a pivot 40, and a conductive slip ring 50. The control component 21 is installed within the base 20. The slide 30 is slidably mounted on the base 20, and an electrical module 31 is fixedly disposed within the slide 30, electrically connected to the control component 21. The pivot 40 is rotatably mounted on the slide 30 and is used to connect to the camera's electrical control mounting platform 900. The pivot 40 is provided with conductive terminals 41 for forming conductive contact with the electrical control mounting platform 900. The conductive slip ring 50 forms electrical connections with both the electrical module 31 and the conductive terminals 41 of the pivot 40.

[0039] Specifically, the electrical control mounting platform 900 has a contact terminal 901 for electrical connection with the conductive terminal 41. After the electrical control mounting platform 900 is mounted on the axis 40 of the photographic slide rail device 100 of this application, the contact terminal 901 of the electrical control mounting platform 900 and the electrical module 31 form a conductive contact through the conductive terminal 41 of the axis 40 and the conductive slip ring 50, thereby realizing electrical connection.

[0040] The conductive slip ring 50 includes a rotating part 52 and a fixed part 51. The rotating part 52 can rotate relative to the fixed part 51, slides in contact with the fixed part 51 and is electrically connected, thereby forming a stable electrical connection when rotating.

[0041] In this embodiment, the rotating part 52 of the conductive slip ring 50 is fixedly connected to the shaft platform 40 and rotates together with the shaft platform 40. The fixed part 51 is fixedly connected to the slide block 30. The fixed part 51 is electrically connected to the electrical module 31, and the rotating part 52 is electrically connected to the conductive terminal 41. Specifically, the rotating part 52 is electrically connected to the conductive terminal 41 of the shaft platform 40 through the lead wire 53, and thus forms an electrical connection with the control component 21. Therefore, the control component 21 and the electrical module 31 are electrically connected to the electrical control mounting platform 900 through the conductive slip ring 50 and the conductive terminal 41, so that the power supply current can be output to the electrical control mounting platform 900 through the conductive terminal 41, avoiding the need for the electrical control mounting platform 900 to be equipped with a separate battery, which helps to simplify the structure of the electrical control mounting platform 900. Meanwhile, the control component 21 and the electrical module 31 form a wired power supply and signal connection with the electrical control mounting platform 900 through the conductive terminal 41, which makes the motion coordination signal highly stable when transmitted between the electrical module 31 and the electrical control mounting platform 900. This avoids the insufficient precision of synchronous control between different actions caused by signal delay in wireless connections (such as Bluetooth connections), thus ensuring the user experience of the camera slider device 100.

[0042] Specifically, the motion coordination signal can be transmitted from the electrical module 31 to the electrical control mounting platform 900, or vice versa. The motion coordination signal is used to ensure that the translation and rotation of the axis table 40 maintain a certain synchronization with the motion mode controlled by the electrical control mounting platform 900.

[0043] In some embodiments, at least one interface end of the conductive slip ring 50 is constructed as 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. In some embodiments, combined with 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 fixing 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.

[0044] Specifically, the control component 21 can be connected to an external power source to provide power to the electrical module 31 and the electrical control mounting platform 900, enabling them to operate normally. The control component 21 may also include a built-in battery, particularly a rechargeable battery, to meet the camera's power supply requirements while also achieving portability.

[0045] In some embodiments, the control component 21 can also be used to control the linear movement of the slide 30 relative to the base 20. In some embodiments, the control component 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 execution result signals to the control component 21.

[0046] In some implementations, combined Figure 1 and Figure 2 As shown, a guide rod 22 is mounted on the base 20. A slide 30 is slidably fitted onto the outer periphery of the guide rod 22, thereby guiding the sliding direction of the slide 30 relative to the base 20. In some embodiments, two guide rods 22 are mounted parallel to each other on the base 20. Furthermore, the slide 30 is simultaneously defined by both guide rods 22, with the center of the slide 30 located between the two guide rods 22.

[0047] Combination Figures 5 to 7As shown, the shaft platform 40 includes a cover 42 rotatably disposed relative to the slide 30 and an insulating member 46 mounted on the cover 42. A plurality of conductive terminals 41 are spaced apart and inserted into the insulating member 46. Specifically, the plurality of conductive terminals 41 are fixedly inserted into the insulating member 46 at intervals, thereby ensuring the stable position of each conductive terminal 41. Because the insulating member 46 is insulating, short circuits between the conductive terminals 41 are prevented. Simultaneously, the insulating member 46 and the plurality of conductive terminals 41 can form a pre-assembled assembly; when the insulating member 46 is installed onto the cover 42, the plurality of conductive terminals 41 are simultaneously installed onto the cover 42, thereby improving the installation efficiency of the conductive terminals 41.

[0048] In some other embodiments, when the faceplate 42 is made of insulating material, the conductive terminal 41 may be directly mounted on the faceplate 42.

[0049] In some implementations, combined Figure 6 and Figure 7 As shown, the cover 42 has 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 separated from a portion of the surface of the cover 42 by a small distance. At the same time, the conductive terminal 41 can extend to the inside of the cover 42 through the slot 421.

[0050] In some embodiments, the insulating element 46 is at least partially exposed outside the faceplate 42, so that after the electrical control mounting platform 900 is mounted on the shaft base 40, the outer surface of the insulating element 46 can be opposite to the distribution area of ​​the contact terminals 901 of the electrical control mounting platform 900.

[0051] In some implementations, combined Figure 2 As shown, the outer end face of the conductive terminal 41 is flush with the outer surface of the insulating component 46, thereby keeping the outer surface of the insulating component 46 flat. When the contact terminal 901 of the electrical control mounting platform 900 adopts an elastic pin structure, it avoids the conductive terminal 41 from causing sliding obstruction to the contact terminal 901 of the electrical control mounting platform 900.

[0052] In some implementations, 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 faces of two adjacent conductive terminals 41. Specifically, the raised portion 461 can maintain a distance between other external metal parts and the outer surface of the insulating member 46, preventing external metal parts from simultaneously making conductive contact with the outer end faces of two conductive terminals 41, and preventing short circuits between two conductive terminals 41 with a potential difference. Specifically, depending on the intended use of the conductive terminals 41, it can be determined whether there is a potential difference between the conductive terminals 41. When arranging the conductive terminals 41, two conductive terminals 41 with a potential difference can be disposed on both sides of the raised portion 461.

[0053] In some implementations, combined Figure 5 As shown, the faceplate 42 is connected to two opposing limiting blocks 422. A directional groove 423 is formed between the two limiting blocks 422. Specifically, the electrical control mounting platform 900 is partially accommodated within the directional groove 423. Under the constraint of the limiting blocks 422, the electrical control mounting platform 900 can slide within the directional groove 423. Specifically, the directional groove 423 is shaped similarly to a dovetail groove. The electrical control mounting platform 900 has a structure similar to a dovetail block to mate with the directional groove 423. Specifically, the extending direction of the protrusion 461 corresponds to the sliding direction of the electrical control mounting platform 900 within the directional groove 423.

[0054] In some implementations, combined Figure 5 and Figure 6 As shown, the cover 42 has a first end 424 and a second end 425 facing each other. The first end 424 is used for the power control mounting platform 900 to enter the orientation groove 423. The outer surface of the insulating member 46 includes a mating surface 462 and a transition slope 463 arranged adjacently, with the mating surface 462 protruding relative to the bottom surface of the orientation groove 423. Conductive terminals 41 are distributed on the mating surface 462. The transition slope 463 is close to the first end 424 of the cover 42 relative to the mating surface 462. Along the direction from the second end 425 to the first end 424, the transition slope 463 is inclined in the direction close to the bottom surface of the orientation groove 423. Specifically, when the contact terminal 901 of the power control mounting platform 900 adopts a flexible pin structure, after the power control mounting platform 900 slides into the orientation groove 423 from the first end 424, the power control mounting platform 900 slides along the direction from the first end 424 to the second end 425, and the contact terminal 901 first contacts the transition slope 463. The transition slope 463 gradually compresses the contact terminal 901, preventing the end of the contact terminal 901 from getting stuck during sliding. Since the mating surface 462 protrudes relative to the bottom surface of the orientation groove 423, and the outer end face of the conductive terminal 41 is flush with the mating surface 462, the contact terminal 901 of the electrical control mounting platform 900 remains in a compressed state when it contacts the conductive terminal 41, thereby keeping the contact terminal 901 and the conductive terminal 41 in close contact and improving the stability of the electrical contact.

[0055] In some embodiments, the distance between the insulating member 46 and the second end 425 is less than the distance between the insulating member 46 and the first end 424.

[0056] In some implementations, combined Figure 5 and Figure 7As shown, the faceplate 42 is connected to a positioning assembly, which restricts the electrical control mounting platform 900 from retracting from the orientation groove 423, thereby confining the electrical control mounting platform 900 onto the axis stage 40. In this fixed position, a plurality of contact terminals 901 of the electrical control mounting platform 900 are precisely aligned with a plurality of conductive terminals 41 on the faceplate 42. In some embodiments, the positioning assembly includes a sliding pin 426. In the reset position, the sliding pin 426 can stop the electrical control mounting platform 900 from sliding towards the first section of the faceplate 42. In the unlocked position, the restriction of the electrical control mounting platform 900 by the sliding pin 426 is released.

[0057] In some implementations, combined Figure 4 and Figure 9 As shown, the slide 30 is equipped with a rotation drive 33. The rotation drive 33 is used to drive the shaft platform 40 to rotate circumferentially. Specifically, the rotation drive 33 drives the shaft platform 40 to rotate circumferentially under the control of the electrical module 31. The electrical module 31 can specifically be a circuit that can control the rotation drive 33 and form an electrical connection with the control component 21.

[0058] In some implementations, combined Figure 6 and Figure 7 As shown, the shaft platform 40 also includes a main shaft body 43. The main shaft body 43 includes a shaft sleeve portion 431 rotatably housed within the slide 30 and a collar portion 432 connected to the shaft sleeve portion 431. A cover 42 is connected to the collar portion 432. Specifically, the shaft sleeve portion 431 and the slide 30 form a rotational engagement, and the rotation drive member 33 transmits driving force to the shaft sleeve portion 431, causing the shaft platform 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 sleeve portion 431. Specifically, the shaft sleeve portion 431 is hollow.

[0059] Combination Figure 6 and Figure 7 As shown, in some embodiments, the slide 30 is further equipped with a first radial bearing 281, which is disposed on the outer peripheral side of the shaft sleeve portion 431 and on the inner peripheral side of the slide 30. Specifically, since the outer peripheral side of the shaft sleeve portion 431 and the slide 30 are provided with the first radial bearing 281, direct friction between the shaft sleeve portion 431 and the slide 30 is avoided, ensuring the smooth rotation of the main shaft body 43 and improving the service life of the main shaft body 43 and the slide 30. In some embodiments, the first radial bearing 281 is a deep groove ball bearing.

[0060] In some implementations, combined Figure 6 and Figure 7As shown, the camera slide 30 also includes an axial bearing 35, which is disposed on the outer periphery of the shaft sleeve portion 431 and between the lower side of the collar portion 432 and the slide 30. Specifically, the gravity of the electrical control mounting platform 900 is applied to the collar portion 432, which is located on the upper side of the slide 30. Because the axial bearing 35 is disposed between the lower side 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 the smooth rotation of the spindle body 43 and improving the service life of the spindle body 43 and the slide 30. In some embodiments, the axial bearing 35 is a thrust bearing.

[0061] In some implementations, combined Figure 6 and Figure 8 As shown, the rotating part 52 is fixedly disposed inside the shaft cylinder part 431, and the outer diameter of the rotating part 52 corresponds to the inner diameter of the shaft cylinder part 431. Specifically, by housing the rotating part 52 inside the shaft cylinder part 431, the conductive slip ring 50 can be prevented from occupying other space within the slide block 30. Since the outer diameter of the rotating part 52 corresponds to the inner diameter of the shaft cylinder part 431, the change in the axial position of the conductive slip ring 50 can be reduced during the rotation of the main shaft body 43 relative to the slide block 30.

[0062] In some implementations, combined Figure 6 and Figure 7 As shown, the camera slide rail device 100 also includes a circuit board 44. A conductive terminal 41 is 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 faceplate 42. An electrical connection is formed between the conductive terminal 41 and the interface socket 441 through 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 terminal 41.

[0063] In some implementations, combined Figure 6 and Figure 7 As shown, the collar portion 432 is provided with a receiving groove 433. The opening of the receiving groove 433 faces the cover 42, and the receiving groove 433 communicates with the inner cavity of the shaft cylinder portion 431, so that the receiving groove 433 can accommodate the interface socket 441 connected to the circuit board 44, and can accommodate the plug at the end of the cable. Since the receiving groove 433 communicates with the inner cavity of the shaft cylinder portion 431, the cable is prevented from passing through narrow positions, which helps to improve the assembly efficiency of the camera slide rail device 100. Specifically, the circuit board 44 is fixed to the collar portion 432 by fasteners. Specifically, the conductive terminal 41 is soldered and fixed to the circuit board 44.

[0064] In some implementations, combined Figure 8 and Figure 9As shown, the photographic slide rail device 100 also includes a wear-resistant component 36. The wear-resistant component 36 is fixedly installed on the slide block 30 and slidably sleeved on the outer periphery of the guide rod 22. Specifically, the wear-resistant component 36 moves with the slide block 30 relative to the base 20 and is spaced apart between the guide rod 22 and the slide block 30, avoiding direct contact between the guide rod 22 and the slide block 30, thereby preventing wear on the slide block 30 or the guide rod 22. In some embodiments, the wear-resistant component 36 is a bushing. Furthermore, the hardness of the wear-resistant component 36 is lower than the hardness of the guide rod 22, thereby effectively reducing wear on the guide rod 22.

[0065] In some embodiments, the slide 30 has a through-hole 37. The guide rod 22 passes through the through-hole 37. The inner diameter of the through-hole 37 is slightly larger than the outer diameter of the guide rod 22. In some embodiments, the wear-resistant component 36 is fixed in the through-hole 37 by an interference fit. The inner diameter of the wear-resistant component 36 is larger than the outer diameter of the guide rod 22, and the guide rod 22 slides through the wear-resistant component 36. In other embodiments, the wear-resistant component 36 can also be fixedly connected to the slide 30 by a flange and screws.

[0066] In some implementations, combined Figure 6 and Figure 9 As shown, the output shaft of the rotation drive 33 is connected to the second worm gear 331. A transmission fit is formed between the rotation drive 33 and the second worm gear 331, which can drive the second worm gear 331 to rotate along its own axis.

[0067] In some implementations, combined Figure 7 and Figure 9 As shown, a second worm gear 435 is fixedly connected to the outer periphery of the shaft cylinder 431, and the second worm 331 meshes with the second worm gear 435. Specifically, when the second worm 331 and the second worm gear 435 are meshed, under the transmission action of the worm gear, since the second worm gear 435 is fixedly connected to the shaft cylinder 431, the second worm gear 435 can drive the main shaft 43 to rotate relative to the slide 30. Since the cover 42 of the electronically controlled mounting platform 900 is mounted on the main shaft 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 drive member 33. Therefore, after the position of the slide 30 changes along the linear direction, by adjusting the angle of the main shaft 43 by rotating the drive member 33, the center of the shooting range of the electronically controlled mounting platform 900 can be kept aligned with the shooting target, ensuring the shooting effect. Furthermore, under the transmission action of the worm gear, the rotation speed of the shaft platform 40 can be much lower than the rotation speed of the output shaft of the rotation drive component 33, which is beneficial for accurately adjusting the angle of the electric control mounting platform 900.

[0068] In some embodiments, a second worm gear structure is formed on the outer periphery of the main shaft 43, and the second worm member 331 meshes with the second worm gear structure. Specifically, when the second worm member 331 meshes with the second worm gear structure formed on the outer periphery of the main shaft 43, the second worm member 331 directly drives the main shaft 43 to rotate relative to the slide block 30. In some embodiments, the shaft sleeve portion 431 has a plurality of worm gear teeth protruding outward on its outer peripheral side, and the worm gear teeth mesh with the second worm member 331. In some embodiments, the outer side of the shaft sleeve portion 431 is provided with grooves, and a plurality of grooves are distributed along the outer periphery of the shaft sleeve portion 431, and the shaft sleeve portion 431 meshes with the second worm member 331 at the portion between two adjacent grooves.

[0069] In some implementations, combined Figure 6 and Figure 7 As shown, the shaft base 40 is connected to a threaded component 45, which is threaded onto the outer periphery of the shaft cylinder portion 431, and the second worm gear component 435 is also threaded onto the outer periphery of the shaft cylinder portion 431. Specifically, the threaded component 45 and the second worm gear component 435 are respectively threaded onto the outer periphery of the shaft cylinder portion 431. By utilizing the threaded component 45 to abut against the second worm gear component 435 along the axial direction of the shaft cylinder portion 431, the second worm gear component 435 can be kept in a fixed position and angle relative to the shaft base 40, thus enabling the second worm gear component 435 to drive the shaft base 40 to rotate.

[0070] In some implementations, combined Figure 9 and Figure 10 As shown, the slide 30 is connected to a bracket 38. One end of the bracket 38 has a slot 381, which surrounds the outer periphery of the support bar 23. The elastic helical conductor 24 is partially embedded in the slot 381. Specifically, by partially embedding the elastic helical conductor 24 in the slot 381, the bracket 38 limits the elastic helical conductor 24. When the slide 30 moves relative to the base 20, the portion of the elastic helical conductor 24 between the bracket 38 and the base 20 can expand and contract, preventing the end of the elastic helical conductor 24 from becoming electrically detached from the slide 30. More specifically, the bracket 38 is connected to the slide 30. In one embodiment, one end of the elastic helical conductor 24 is embedded in the slot 381, and the other end is fixed to the base 20.

[0071] In some implementations, 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 slide 30. The elastic spiral conductor 24 is wound around the outer periphery 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 telescopic; when the position of the slide 30 relative to the base 20 changes, the slide 30 stretches the elastic spiral conductor 24, allowing the length of the elastic spiral conductor 24 to adapt to the position change of the slide 30, thereby maintaining the electrical connection between the control component 21 and the electrical module 31 regardless of the position of the slide 30. The extension direction of the support bar 23 is parallel or approximately parallel to the sliding direction of the slide 30. The support bar 23 supports the elastic spiral conductor 24, preventing it from sagging.

[0072] In one embodiment, the elastic helical conductor 24 may include a retractable spring and a flexible conductor, with the flexible conductor spirally attached to the retractable spring, and both the flexible conductor and the retractable spring enclosed within the same insulating sleeve. In another embodiment, the elastic helical conductor 24 may include an elastic conductor enclosed within an insulating sleeve. Specifically, the elastic conductor has a shape memory, meaning that when the tension applied to the elastic conductor is released, the elastic conductor can contract to its shape memory. Specifically, the elastic conductor may be an elastic helical metal wire.

[0073] In some embodiments, the support bar 23 is a taut nylon rope. Further, both ends of the support bar 23 are fixed to the base 20. In other embodiments, the support bar 23 can also be a metal rod.

[0074] In some implementations, combined Figures 10 to 12 As shown, the camera slide rail device 100 also includes a shifting drive 25 and a transmission assembly 26 mounted on the base 20. Specifically, the shifting drive 25 drives the slide 30 to slide linearly relative to the base 20 via the transmission assembly 26. Under the control of the control assembly 21, the shifting drive 25 drives the slide 30 to slide linearly. The control assembly 21 may specifically be a circuit or module capable of controlling the shifting drive 25 and forming an electrical connection with the electrical module 31. In some embodiments, the control assembly 21 includes a display screen to display status information.

[0075] In some implementations, combined Figure 11 and Figure 12As shown, the base 20 is connected to a first worm gear 27 and a drive shaft 28. The first worm gear 27 is rotatably mounted on the base 20. The drive shaft 28 is rotatably mounted on the base 20. In some embodiments, a first worm wheel 29 is fixedly connected to the outer periphery of the drive shaft 28, and the first worm gear 27 meshes with the first worm wheel 29. In other embodiments, a first worm wheel structure is formed on the outer periphery of the drive shaft 28, and the first worm gear 27 meshes with the first worm wheel structure. The output shaft of the shifting drive 25 is connected to the first worm gear 27. The transmission assembly 26 is connected between the drive shaft 28 and the slide 30. The drive shaft 28 forms a transmission engagement with the slide 30 through the transmission assembly 26, and the rotation of the drive shaft 28 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 electrically controlled mounting platform 900 to move in a straight line.

[0076] Specifically, the slide 30 is guided and can slide relative to the base 20 within a straight line. The output shaft of the shift drive 25 can drive the first worm gear 27 to rotate, causing the first worm gear 27 to rotate around its own axis. When the first worm gear 27 meshes with the first worm wheel 29, the first worm wheel 29 can drive the transmission shaft 28 to rotate relative to the base 20. Since the transmission shaft 28 forms a transmission engagement with the slide 30 through the transmission assembly 26, the rotation of the transmission shaft 28 can cause the slide 30 to slide relative to the base 20, thus enabling the shift drive 25 to adjust the position of the slide 30. Under the transmission action of the worm gear, the rotational speed of the transmission shaft 28 is much lower than the rotational speed of the first worm gear 27, thereby accurately controlling the moving speed and position of the slide 30, which is beneficial to improving the accuracy of the position control of the electronically controlled mounting platform 900. In some embodiments, the transmission shaft 28 has several worm gear teeth protruding outward on its outer peripheral side, and the worm gear teeth mesh with the first worm gear 27.

[0077] In some implementations, combined Figures 10 to 12As shown, the transmission assembly 26 includes a driving pulley 261, a driven pulley 262, and a timing belt 263. The driving pulley 261 and driven pulley 262 are rotatably mounted on the base 20. The transmission shaft 28 forms a transmission engagement with the driving pulley 261. The timing belt 263 is suspended on the outer periphery of the driving pulley 261 and driven pulley 262. A slide 30 is connected to the timing belt 263. Specifically, the slide 30 is connected to a short section of the timing belt 263. When the driving pulley 261 rotates, and the short section of the timing belt 263 moves linearly, the slide 30 moves linearly under the traction of the timing belt 263. In some embodiments, the slide 30 is connected to a clamping block 32, which is fixedly disposed to a section of the timing belt 263, thereby enabling the timing belt 263 to drive the slide 30 to move. More specifically, there may be one or more driven pulleys 262. In other embodiments, the transmission assembly 26 includes a lead screw, which is threadedly engaged with the slide 30. The drive shaft 28 can drive the lead screw to rotate. When the lead screw rotates, it drives the slide 30 to move in a straight line.

[0078] Furthermore, combined Figure 12 As shown, a second radial bearing 34 is mounted on the base 20. One end of the drive shaft 28 is inserted into the second radial bearing 34. The other end of the drive shaft 28 is connected to the drive wheel 261.

[0079] In some embodiments, the shifting drive 25 is a stepper motor or a servo motor. In some embodiments, the rotation drive 33 is a stepper motor or a servo motor.
