Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a photographic auxiliary mobile vehicle. Background Technology

[0002] In the field of film and television production, camera support vehicles (also known as director's vehicles) play a crucial role. As a tool vehicle specifically designed for placing or moving camera props on set, they greatly facilitate the filming process. For example, directors can use monitors mounted on the camera support vehicle to monitor the shooting footage in real time and adjust shooting strategies accordingly. Simultaneously, the vehicle can also accommodate various camera equipment such as cameras, lens hoods, tripods, and spare batteries, providing ample and convenient equipment support for the filming process.

[0003] Currently, photography-assisted mobile carts in related technologies are mainly divided into two categories. One type is electrically adjustable photography-assisted mobile carts, whose platform typically relies on drive modules such as lead screws to achieve lifting. However, due to the complex structure of the drive module, it occupies a large space, making it difficult to store the cart after shooting, especially in space-constrained shooting locations or during transportation. This problem is particularly prominent, severely impacting the vehicle's storage convenience. The other type is manually adjustable photography-assisted mobile carts, which adjust the height of the platform manually. When storage is needed, its relatively simple structure allows for disassembly and storage without taking up too much space. However, the manual adjustment process is cumbersome, failing to meet the need for quick height adjustments on-site. Lacking the convenience and efficiency of electrically adjustable mechanisms, it significantly affects the efficiency of shooting work and the user experience.

[0004] Therefore, there is an urgent need to provide a new photography-assisted mobile vehicle to solve the above problems and improve the performance and practicality of the photography-assisted mobile vehicle in actual shooting applications. Utility Model Content

[0050] In view of the shortcomings of the related technologies pointed out in the background art, this utility model embodiment proposes a photography auxiliary mobile cart that combines electric lifting function with convenient storage, thereby improving the performance and practicality of the photography auxiliary mobile cart in actual shooting applications. It should be noted that the photography auxiliary mobile cart involved in this embodiment is not limited to the name "photography auxiliary mobile cart," and terms such as "director's cart" and "camera trolley" are also applicable.

[0051] Reference Figures 1 to 3 The photography-assisted mobile vehicle includes:

[0052] First shelf 100;

[0053] The second shelf 200 is arranged vertically opposite to the first shelf 100;

[0054] A support chain module 300 is disposed on the first shelf 100 and connected to the second shelf 200. The support chain module 300 is used to support the second shelf 200 and can drive the second shelf 200 to rise or fall relative to the first shelf 100.

[0055] A drive component 400 is disposed on the first platform 100 and connected to the support chain module 300. The drive component 400 is used to drive the support chain module 300 to operate.

[0056] like Figure 1 As shown, the first storage platform 100 serves as a basic support platform for placing some photography props and installing other key components. Vertically (perpendicular to the vehicle's travel surface), the second storage platform 200 is positioned opposite the first storage platform 100 and can be used to place different types of photography equipment, working in conjunction with the first storage platform 100 to increase the vehicle's storage space. Both the first and second storage platforms 100 can adopt structural forms such as frames, cabinets, or boxes, providing storage space for accommodating photography props / equipment.

[0057] A support chain module 300 is mounted on the first shelf 100, with one end securely connected to the first shelf 100 and the other end connected to the second shelf 200, providing crucial support for the second shelf 200. Besides this support function, the core function of the support chain module 300 is to drive the second shelf 200 to rise or fall relative to the first shelf 100, achieving flexible adjustment of the shelf height. Specifically, the support chain module 300 is a lifting module mainly composed of chains, which controls the change in the extension length of the chains to drive the movement of the second shelf 200, thus achieving lifting and lowering.

[0058] The drive assembly 400 is installed on the first shelf 100 and establishes a drive connection with the support chain module 300. The drive assembly 400 serves as a power output source, driving the support chain module 300 to provide power support for the lifting and lowering of the second shelf 200. The drive assembly 400 may include a drive motor and a transmission device. The output shaft of the drive motor is connected to the transmission device, which is connected to the support chain module 300. The transmission device can be, for example, a gear or belt. When the drive motor is running, it transmits power to the support chain module 300 through the transmission device, enabling the support chain module 300 to operate.

[0059] like Figure 1 and Figure 2As shown, in actual shooting scenarios, such as film and television shooting in an indoor studio, the director needs to frequently adjust the height of the camera platform according to the actors' positions and the composition requirements of the shot. At this time, the staff can control the drive component 400 of this camera auxiliary moving vehicle to start, thereby driving the support chain module 300 to run. The support chain module 300 drives the second platform 200 to rise or fall relative to the first platform 100, so as to adjust the second platform 200 to the required height.

[0060] like Figure 3 As shown, when the filming is finished and the vehicle needs to be stored, the drive assembly 400 can be controlled to drive the support chain module 300, causing the second storage platform 200 to descend to its lowest position and overlap with the first storage platform 100. At this time, the support chain module 300 is compactly stored within the area of ​​the first storage platform 100, without taking up much space. This easily handles storage in a cramped corner of a photography studio or during long-distance transportation.

[0061] This photography-assisted mobile vehicle automatically drives the support chain module 300 through the drive component 400, eliminating the cumbersome manual operation process and enabling rapid adjustment of the platform height. At the same time, the second platform 200 can be lowered to its lowest position along with the support chain module 300 and overlapped with the first platform 100 for storage. The support chain module 300 retracts accordingly during storage, without occupying a large space, making storage convenient and transportation flexible.

[0062] This utility model of a camera assistance mobile vehicle successfully balances the two key factors of electric lifting function and convenient storage through ingenious structural design and component configuration. In practical shooting applications, it can provide directors and shooting teams with convenient and efficient shooting assistance, and also demonstrates good space utilization characteristics during shooting breaks and transportation and storage. It comprehensively improves the performance and practicality of the camera assistance mobile vehicle in the entire film and television shooting process, bringing a higher quality and more efficient shooting equipment solution to the film and television shooting industry.

[0063] In some embodiments, refer to Figure 1 and Figure 2 The number of support chain modules 300 is set to one or more, and the one or more support chain modules 300 are distributed around the periphery of the first shelf 100.

[0064] The number of support chain modules 300 can be set to one or more. For example, the number of support chain modules 300 can be set to two. When the photography auxiliary mobile vehicle is equipped with two support chain modules 300, the two support chain modules 300 can be arranged opposite each other on the front and rear sides or left and right sides of the first platform 100. Alternatively, the number of support chain modules 300 can be set to two. When the photography auxiliary mobile vehicle is equipped with three support chain modules 300, two of the support chain modules 300 can be arranged opposite each other on the left and right sides of the first platform 100, and the third support chain module 300 can be arranged on the front or rear side of the first platform 100.

[0065] Based on one or more support chain modules 300, there may be one drive component 400, which provides driving power to one or more support chain modules 300 to drive them to run synchronously; or, there may be one or more drive components 400, each drive component 400 providing driving power to one support chain module 300 to drive the corresponding support chain module 300 to run. The configuration can be set according to actual needs, and this embodiment does not impose any restrictions on this.

[0066] In this embodiment, by setting multiple support chain modules 300 to work together, the stability of the second platform 200 during the lifting process can be ensured, and tilting or other situations can be avoided.

[0067] In some embodiments, refer to Figure 2 and Figure 4 Each support chain module 300 has a power input unit 301;

[0068] The drive assembly 400 is connected to the power input section 301 of each support chain module 300, and the power input section 301 is used to receive the drive power output by the drive assembly 400.

[0069] When the drive assembly 400 starts, it outputs drive power to the power input section 301 of each support chain module 300. After receiving the drive power, the power input section 301 of each support chain module 300 then operates synchronously to drive the second shelf 200 to rise or fall relative to the first shelf 100. The power input section 301 of the support chain module 300 can be a power input shaft, and the power input shaft is connected to the drive assembly for transmission.

[0070] Among them, the drive component 400 serves as the sole power source, providing driving power to each support chain module 300. This ensures the synchronization and consistency of the operation of each support chain module 300, helps improve the smoothness of the lifting and lowering action of the second platform 200, and enables precise and stable adjustment of the platform height.

[0071] In some embodiments, refer to Figure 2The driver component 400 includes:

[0072] A drive unit 410 is disposed on the first shelf 100;

[0073] A transmission rod assembly 420 is disposed on the first shelf 100. The transmission rod assembly 420 has a power input end 4201 and multiple power output ends 4202. The power input end 4201 of the transmission rod assembly 420 is connected to the power output part of the drive member 410. Each power output end 4202 of the transmission rod assembly 420 is connected to the power input part 301 of a support chain module 300.

[0074] The drive component 410, as the power source of the entire drive assembly 400, is responsible for converting electrical energy into power output that can be transmitted. The drive component 410 can be a drive motor. Corresponding to the drive component 410, the power input end 4201 of the transmission rod assembly 420 is connected to the power output part of the drive component 410, and corresponding to the multiple support chain modules 300, each power output end 4202 of the transmission rod assembly 420 is connected to the power output part of one support chain module 300.

[0075] As an example, the transmission rod assembly 420 may include a transmission rod that is connected to the drive member 410. The middle end of the transmission rod corresponds to the power input end 4201, and the two opposite ends of the transmission rod correspond to two power output ends 4202, which are respectively connected to the power input parts 301 of the two support chain modules 300. Alternatively, the transmission rod assembly 420 may include two transmission rods, namely a first transmission rod and a second transmission rod. The first transmission rod is connected to the drive member 410, the middle end of the first transmission rod corresponds to the power input end 4201, and the two opposite ends of the first transmission rod correspond to two power output ends 4202, which are respectively connected to the power input parts 301 of the two support chain modules 300. One end of the second transmission rod is connected to the first transmission rod, and the other end of the second transmission rod corresponds to a power output end 4202, which is connected to the power input part 301 of one support chain module 300.

[0076] When the drive component 410 is working, its power output section outputs driving power, which is transmitted to the transmission rod assembly 420 via the power input end 4201 of the transmission rod assembly 420, driving the transmission rod assembly 420 to run. At the same time, each power output end 4202 of the transmission rod assembly 420 transmits driving power to the power output section of the support chain module 300 connected to it, causing the support chain module 300 to run. In this embodiment, through the coordinated connection of the drive component 410, the transmission rod assembly 420 and the power input sections 301 of each support chain module 300, precise synchronous driving of multiple support chain modules 300 is achieved.

[0077] In some embodiments, refer to Figure 2 The first shelf 100 is provided with one or more openings 101, and the power input part 301 of each support chain module 300 passes through one opening 101 and extends to the side of the first shelf 100 facing away from the second shelf 200.

[0078] The drive unit 410 is installed on the side of the first shelf 100 facing away from the second shelf 200. The drive unit 410 includes a drive motor 411 and a worm gear reducer 412 connected to the output shaft of the drive motor 411. The transmission rod assembly 420 includes a transmission rod 421, which passes through and is connected to the worm gear reducer 412. The two opposite ends of the transmission rod 421 are respectively connected to the power input part 301 of a support chain module 300.

[0079] When the height of the second shelf 200 needs to be adjusted, the drive motor 411 starts running. The output shaft of the drive motor 411 rotates at high speed, generating initial power and transmitting it to the worm gear reducer 412 connected to it. The worm gear reducer 412 reduces and increases the torque of the high-speed, low-torque power output by the drive motor 411, making the output power more suitable for driving the operation of subsequent components.

[0080] The power processed by the worm gear reducer 412 is transmitted to the transmission rod 421, which drives the transmission rod 421 to rotate synchronously. As the transmission rod 421 rotates, the power is precisely transmitted to the power input section 301 of each support chain module 300, so that each support chain module 300 operates smoothly and precisely, driving the second shelf 200 to rise or fall relative to the first shelf 100, thus realizing flexible adjustment of the shelf height.

[0081] In this embodiment, the combination of the drive motor 411 and the worm gear reducer 412 enables precise control of the output power, ensuring the stability and continuity of power transmission. Furthermore, the transmission rod 421 evenly distributes power to each support chain module 300. The coordinated operation of multiple support chain modules 300 ensures that the second platform 200 experiences uniform force during lifting and lowering, maintaining a horizontal position and precisely meeting the stringent requirements of film and television shooting for the stability of platform height adjustment. Moreover, the design of the drive component 410 and the transmission rod assembly 420 being installed on the side of the first platform 100 facing away from the second platform 200, with an opening 101 through the first platform 100, allows the power input part 301 of the support chain module 300 to pass through the opening 101 and connect to the transmission rod assembly 420. This design optimizes the spatial layout, minimizing the storage space occupied by the first platform 100 and resulting in a compact structure.

[0082] In some embodiments, refer to Figure 2 The driver component 400 also includes:

[0083] A control board is disposed on the first platform 100 and electrically connected to the drive unit 410. The control board is used to control the operation of the drive unit 410.

[0084] The battery box 430 is located on the first shelf 100 and is electrically connected to the control board.

[0085] The control board (i.e., control circuit board) and battery box 430 can be located on the side of the first shelf 100 facing away from the second shelf 200, or they can be located on the peripheral surface of the first shelf 100, thus avoiding occupying the storage space of the first shelf 100. In practical applications, the staff can send commands to the control board by operating the control buttons on the mobile vehicle or through a mobile terminal (such as a mobile phone) APP / mini-program. After receiving the command, the control board quickly transmits the electrical signal to the drive component 410 that is electrically connected to it. The drive component 410 outputs driving power and transmits it through the transmission rod assembly 420, so that the support chain module 300 runs, thereby driving the second shelf 200 to rise or fall to the required height.

[0086] The battery box 430, as an independent power supply unit, provides stable power to the control board and drive unit 410. This design eliminates the dependence on external power sources, enabling the camera-assisted mobile vehicle to be used flexibly in various shooting environments, whether in indoor studios with limited power interfaces or outdoor shooting locations without power supply, ensuring the normal operation of the vehicle's platform lifting function.

[0087] In some embodiments, refer to Figure 4 and Figure 5 The support chain module 300 includes:

[0088] The housing 310 is connected to the first shelf 100; the housing 310 provides protection and a mounting base for the internal components.

[0089] The support chain 320 is vertically mounted on the box 310 and connected to the second shelf 200; wherein, the support chain 320 is the direct actuator for raising and lowering the second shelf 200.

[0090] A gear set 330 is disposed in the housing 310 and is connected to the support chain 320 for transmission. The gear set 330 is used to receive the driving power output by the drive assembly 400 and drive the support chain 320 to rise or fall. The function of the gear set 330 is to receive the driving power output by the drive assembly 400 and, through its own gear transmission structure, convert the power into the driving force for the support chain 320 to rise or fall.

[0091] When the drive assembly 400 is activated, its output drive power is transmitted to the gear set 330 of the support chain module 300. The driving gear in the gear set 330 begins to rotate under the action of the drive power. The driving gear, through precise meshing with the driven gear, transmits the rotational motion to a specific gear connected to the support chain 320 (such as the transmission gear 331 in a later embodiment). As this specific gear continues to rotate, the support chain 320 rises or falls along a predetermined track within the housing 310, directly driving the second shelf 200 to rise or fall relative to the first shelf 100. In this process, the precise transmission of the gear set 330 ensures the smoothness and accuracy of the movement of the support chain 320, ultimately achieving flexible and stable adjustment of the shelf height.

[0092] In some embodiments, refer to Figure 5 The box 310 has a main channel 311 and two recycling channels 312. The main channel 311 extends along the height of the box 310. One end of the main channel 311 has a channel outlet. The two recycling channels 312 are separately located on opposite sides of the main channel 311 and are connected to the other end of the main channel 311.

[0093] The support chain 320 includes two opposing chain bodies 321. One of the chain bodies 321 is housed in one of the two recycling channels 312 and the main channel 311, and extends out from the channel outlet. The other chain body 321 is housed in the other of the two recycling channels 312 and the main channel 311, and extends out from the channel outlet. The extended ends of the two chain bodies 321 are connected to a connecting seat 322, and are connected to the second shelf 200 through the connecting seat 322.

[0094] The gear set 330 includes two transmission gears 331, which are respectively meshed with two chains 321 and are used to engage the transmission chains 321 to rise or fall by rotation; during the rising process, the two chains 321 move from the recovery channel 312 toward the main channel 311 to close in opposite directions, and during the falling process, they move from the main channel 311 toward the recovery channel 312 to separate in opposite directions.

[0095] When the height of the second shelf 200 needs to be adjusted, the drive assembly 400 is activated and outputs drive power to the gear set 330 of the support chain module 300. The two transmission gears 331 in the gear set 330 rotate in opposite directions under the action of the drive power. The two chain bodies 321 that mesh with the transmission gears 331 begin to move under the meshing transmission of the transmission gears 331.

[0096] Specifically, during the ascent, as the transmission gear 331 rotates, the chain 321 is subjected to an upward force, gradually moving from the recovery channel 312 to the main channel 311. The two chains 321 approach each other and can interlock. Since the two chains 321 are connected to the second shelf 200 through the connecting seat 322, the ascent of the chains 321 drives the second shelf 200 to rise synchronously.

[0097] During the descent, the drive assembly 400 rotates in the opposite direction, the transmission gear 331 rotates in the opposite direction, the chain 321 is subjected to a downward force and moves from the main channel 311 to the recovery channel 312, the two chains 321 separate in opposite directions, thereby driving the second platform 200 to descend.

[0098] The design of the recycling channel 312 inside the box 310 allows the support chain 320 to be recycled in an orderly manner from the main channel 311 into the recycling channel 312 when it is stored. The entire support chain module 300 has a compact structure and does not take up too much space.

[0099] In some embodiments, refer to Figure 5 The recycling channel 312 includes a first sub-recycling channel 3121 and a second sub-recycling channel 3122. The second sub-recycling channel 3122 and the first sub-recycling channel 3121 are arranged side by side along the height direction of the box body 310. One end of the first sub-recycling channel 3121 is connected to the main channel 311, and the other end of the second sub-recycling channel 3122 is connected to the first sub-recycling channel 3121.

[0100] In the height direction of the box body 310, the first sub-recycling channel 3121 may be located below the second sub-recycling channel 3122, and the second sub-recycling channel 3122 may be located above the first sub-recycling channel 3121; or the second sub-recycling channel 3122 may be located below the first sub-recycling channel 3121, and the first sub-recycling channel 3121 may be located above the second sub-recycling channel 3122.

[0101] As the support chain 320 rises, the chain 321 extends outward from the outlet of the main channel 311, and the chain 321 inside the box 310 moves from the second sub-recycling channel 3122 toward the first sub-recycling channel 3121; while as the support chain 320 descends, the chain 321 retracts inward from the outlet of the main channel 311, and the chain 321 inside the box 310 moves from the first sub-recycling channel 3121 toward the second sub-recycling channel 3122.

[0102] In this embodiment, the dual-sub-recycling channel design of the first sub-recycling channel 3121 and the second sub-recycling channel 3122 adopted by the recycling channel 312 allows the chain 321 to be folded and accommodated along the height direction of the box 310 during the recycling process, thereby avoiding occupying a large space in the length direction of the shelf and helping to improve the structural compactness.

[0103] In some embodiments, refer to Figure 1 The photography-assisted mobile vehicle also includes:

[0104] Multiple wheel assemblies 500 are disposed on the first shelf 100, and the wheel assemblies 500 move on the walking surface to drive the first shelf 100 to move.

[0105] The number of wheel assemblies 500 can be set to two or more. For example, the number of wheel assemblies 500 can be set to three. When the photography-assisted mobile vehicle is equipped with three wheel assemblies 500, two of the wheel assemblies 500 are arranged opposite each other on the left and right sides of the first platform 100, and the third wheel assembly 500 can be arranged on the front side of the first platform 100. Alternatively, the number of wheel assemblies 500 can be set to four. When the photography-assisted mobile vehicle is equipped with four wheel assemblies 500, two of the wheel assemblies 500 are arranged on the left side of the first platform 100 and spaced apart in the front-back direction, and the other two wheel assemblies 500 are arranged on the right side of the first platform 100 and spaced apart in the front-back direction.

[0106] The wheel assembly 500 may include a wheel frame and wheels rotatably mounted on the wheel frame, the wheel frame being connected to the first shelf 100. Each wheel assembly may be equipped with an electric drive module to drive the wheel assembly and control the mobile vehicle to move automatically without manual pushing. Furthermore, the type of wheel may be a Mecanum wheel, including but not limited to this.

[0107] The multiple wheel assemblies (500 units) allow the camera assistance mobile vehicle to move easily across different shooting locations. Whether on a flat indoor studio floor or in complex outdoor shooting terrain, it can be quickly and flexibly repositioned to meet the needs of flexible equipment movement during film and television shooting, greatly improving the convenience of shooting work.

[0108] The second storage platform 200 can be equipped with a handle 800, which allows users to drag or push the photography auxiliary mobile vehicle by holding the handle 800, making it convenient to use.

[0109] In some embodiments, refer to Figure 6 The photography-assisted mobile vehicle also includes:

[0110] The mounting bracket 600 is located on the first shelf 100 and spaced apart from the support chain module 300.

[0111] The second shelf 200 and the mounting bracket 600 are slidably connected.

[0112] In this embodiment, the mounting frame 600 is mounted on the first platform 100 to construct the three-dimensional structure of the mobile vehicle and provide necessary structural support for the sliding of the second platform 200. The second platform 200 may be fitted onto the mounting frame 600, which is equipped with a guide rail assembly. The second platform 200 is connected to the mounting frame 600 via a slider of the guide rail assembly, allowing for slidable connection. The guide rail assembly typically consists of a guide rail and a corresponding slider. The shape and size of the guide rail are designed according to the structure of the mounting frame 600 and the movement requirements of the second platform 200. It is generally a linear guide rail with a smooth surface and high precision, providing a stable sliding track for the slider. The second platform 200 is fitted onto the mounting frame 600 and connected to the slider of the guide rail assembly. This connection allows the second platform 200 to slide on the guide rail with the aid of the slider. For example, when adjusting the position of the second platform 200, it slides smoothly on the guide rail via the slider.

[0113] In some embodiments, refer to Figure 6 and Figure 7 The photography-assisted mobile vehicle also includes:

[0114] The lifting module 700 is mounted on the mounting frame 600 and connected to the second storage platform 200. The lifting module 700 is used together with the support chain module 300 to drive the second storage platform 200 to rise or fall relative to the first storage platform 100.

[0115] The lifting module 700 can be a linearly driven structural module such as a lead screw, synchronous belt, hydraulic cylinder, or linear motor, selected according to actual needs; this embodiment does not impose any restrictions. The support chain module 300 works in conjunction with the lifting module 700 to support the second shelf 200 and can move the second shelf 200 toward or away from the first shelf 100, achieving flexible adjustment of the shelf height.

[0116] The lifting module 700 and the support chain module 300 can each have their own drive unit to output driving power to drive the modules when adjusting the height of the storage platform; alternatively, the vehicle is equipped with a drive assembly 400 corresponding to the lifting module 700 and the support chain module 300. The drive assembly 400 is located on the first storage platform and establishes a drive connection with the lifting module 700 and the support chain module 300. The drive assembly 400 serves as a power output source, driving the lifting module 700 and the support chain module 300 to provide power support for the lifting of the second storage platform. The specific implementation structure of the drive assembly 400 can be referred to in the aforementioned embodiments and will not be detailed here.

[0117] In some embodiments, refer to Figure 6 and Figure 7 The lifting module 700 includes at least one lead screw assembly 710, which includes a lead screw 711 and a nut seat 712 sleeved on the lead screw 711. The lead screw 711 is rotatably mounted on the mounting frame 600, and the nut seat 712 is connected to the second platform 200.

[0118] When the drive structure of the camera-assisted mobile cart is operational, power is transmitted to the lead screw 711 of the lead screw assembly 710, driving the lead screw 711 to rotate around its axis. Because the nut seat 712 is threadedly engaged with the lead screw 711 and connected to the second platform 200, the rotation of the lead screw 711 causes the nut seat 712 to move along the axial direction of the lead screw 711, thereby raising and lowering the second platform 200. Throughout the process, the lead screw assembly 710 and the support chain module 300 operate synchronously, ensuring the smooth and precise raising and lowering of the second platform 200. The lead screw assembly 710 maintains stable operation even under heavy loads, working in conjunction with the support chain module 300 to significantly enhance the camera-assisted mobile cart's load-bearing capacity for photographic equipment, meeting the needs of photographic equipment of different sizes and weights. Furthermore, the lead screw assembly 710 has a relatively simple structure; when a component malfunctions, technicians can quickly locate, repair, or replace it, reducing maintenance time and costs, improving equipment maintainability, shortening equipment downtime, and ensuring the smooth progress of shooting operations.

[0119] Among them, such as Figure 7 As shown, the number of lead screw assemblies 710 can be set to two, with the two lead screw assemblies 710 arranged side by side and spaced apart on the mounting frame 600. The dual lead screw assemblies 710, in conjunction with the support chain module 300, provide support to the second platform 200 from multiple support points. When the second platform 200 is raised or lowered, the two lead screw assemblies 710 operate synchronously, effectively preventing the second platform 200 from tilting due to uneven force distribution or malfunction of a single lead screw assembly 710. This greatly improves the stability of the second platform 200 during raising and lowering, providing a more reliable working platform for the photographic equipment and reducing deviations in the shooting image caused by platform shaking. Furthermore, the application of dual lead screw assemblies 710 distributes the weight of the second platform 200 and the photographic equipment it supports. Compared to a single lead screw assembly 710, two lead screw assemblies 710 can withstand a greater load, further enhancing the carrying capacity of the photographic auxiliary mobile vehicle for large and heavy photographic equipment and meeting diverse shooting needs.
