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] In current film and television shooting practices, most common camera support mobile vehicles are equipped with electric lifting functions. This function is mainly achieved through the coordinated operation of a storage platform and a lifting module. The storage platform is responsible for carrying camera equipment and related props, while the lifting module is the core component that enables the storage platform to lift and lower. However, in actual application scenarios of these camera support mobile vehicles, the connection structure design between the lifting module and the storage platform has certain flaws. When it is necessary to disassemble and install the two, the staff has to use multiple tools such as wrenches and screwdrivers, and the operation process is extremely complicated. Each connection part requires multiple tightening or loosening processes, which consumes a lot of time. This not only causes the equipment to be unable to be used normally for a long time, but may also delay the shooting schedule. Utility Model Content

[0004] The main purpose of this utility model is to propose a photography-assisted mobile vehicle, which aims to solve the technical problem that the disassembly and installation of the lifting module and the placement platform of the existing photography-assisted mobile vehicle requires tools and is complicated and time-consuming.

[0005] To achieve the above objectives, this utility model proposes a photography-assisted mobile vehicle, comprising:

[0006] First shelf;

[0007] The second shelf is arranged vertically opposite to the first shelf;

[0008] A lifting module is installed on the first storage platform;

[0009] The lifting module and the second storage platform are provided with a locking structure and a locking tongue, respectively. The lifting module is detachably connected to the second storage platform by locking the locking tongue and the locking structure, and can drive the second storage platform to rise or fall relative to the first storage platform.

[0010] In some embodiments, the locking tongue is disposed on the lifting module;

[0011] The locking structure includes:

[0012] A retaining member is provided on the second shelf, and the retaining member has a locking groove that is adapted to the locking tongue;

[0013] A retaining member is movably disposed on the second shelf, the retaining member being used to press against the latch to engage the latch in the locking groove or to release the latch so that the latch can be disengaged from the locking groove;

[0014] A reset member acts on the abutment member, and the reset member is used to provide a force to reset the abutment member.

[0015] In some embodiments, the locking groove is provided with a slot for the locking tongue to enter or exit the locking groove along its sliding direction;

[0016] The abutment is used to block the slot so that the bolt engages in the locking slot or to open the slot so that the bolt can disengage from the locking slot.

[0017] In some embodiments, the retaining member has a channel located on one side of the locking groove and communicating with the locking groove;

[0018] The abutment is housed in the channel and slides with the channel, and can enter the locking groove through the side wall of the locking groove to block the opening of the groove or exit from the locking groove to open the opening of the groove.

[0019] In some embodiments, the abutment has an abutment portion that can enter or exit the locking groove and a control portion that is at least partially exposed outside the channel, the abutment portion being used to block or open the groove, and the control portion being used to move the abutment portion.

[0020] In some embodiments, the channel includes a first sub-channel and a second sub-channel that are connected in a bent manner, and the second sub-channel is connected to the locking groove.

[0021] The abutment includes a first segment and a second segment that are bent and connected. The first segment is movably disposed in the first sub-channel, and the second segment is movably disposed in the second sub-channel. The abutment part is constructed at the end of the second segment away from the first segment, and the control part is constructed at the end of the first segment away from the second segment.

[0022] In some embodiments, the reset element is a reset spring, which is housed in the second sub-channel, with one end abutting against the groove sidewall of the second sub-channel and the other end abutting against the second segment.

[0023] In some embodiments, the control part is annular.

[0024] In some embodiments, the lifting module includes a drive assembly and a lifting member driven to move up and down by the drive assembly, wherein the locking tongue is fixedly connected to the lifting member; and / or,

[0025] The photography-assisted mobile vehicle also includes a guide structure, which includes a guide bracket and a guide sleeve. The guide bracket extends along the lifting direction of the second platform and is fixed to the first platform. The guide sleeve is fixed to the second platform and slides with the guide bracket.

[0026] In some embodiments, at least two locking structures are provided, spaced apart on the second shelf;

[0027] The locking tongue is provided with at least two, and each locking tongue is locked in engagement with one of the locking structures.

[0028] The camera auxiliary mobile cart provided in this application utilizes a locking mechanism between a latch and a buckle. When lifting is required, the lifting module activates, causing the second platform to rise or fall relative to the first platform. This adjusts the height of the camera equipment and props on the second platform to meet the needs of different shooting scenarios. When disassembling the second platform and the lifting module, simply releasing the locking mechanism allows for separation. Unlike traditional camera auxiliary mobile carts where connecting the lifting module and platform requires multiple tools such as wrenches and screwdrivers and involves complex procedures, this camera auxiliary mobile cart, through its locking mechanism, allows workers to quickly install and disassemble the second platform and the lifting module without tools. This significantly saves time and labor costs, contributing to improved efficiency and quality of the entire film and television shooting project. Attached Figure Description

[0041] Please refer to Figure 1One embodiment of this application proposes a photography-assisted mobile vehicle 100, including a first storage platform 10, a second storage platform 20, and a lifting module 30; the second storage platform 20 and the first storage platform 10 are arranged opposite each other in the vertical direction; the lifting module 30 is disposed on the first storage platform 10.

[0042] The lifting module 30 and the second storage platform 20 are provided with a locking structure 31 and a locking tongue 21. The lifting module 30 is detachably connected to the second storage platform 20 through the locking cooperation of the locking tongue 21 and the locking structure 31, and can drive the second storage platform 20 to rise or fall relative to the first storage platform 10.

[0043] The photography-assisted mobile vehicle 100 consists of a first platform 10, a second platform 20, and a lifting module 30. The second platform 20 is vertically opposite to the first platform 10, and the lifting module 30 is mounted on the first platform 10. This layout lays the foundation for realizing the lifting function of the second platform 20.

[0044] The first platform 10, as a crucial load-bearing component of the entire photography auxiliary moving vehicle 100, provides a stable placement surface for the lifting module 30 and some heavier, larger photographic equipment that does not require frequent position adjustments. It can withstand the forces generated by the lifting module 30 during operation and the weight of the placed equipment, ensuring that the equipment will not affect the shooting results due to shaking or instability during shooting.

[0045] The second platform 20 is mainly used to support photography equipment whose height needs to be adjusted according to the shooting scene, such as cameras and pan-tilt heads. Because it is connected to the lifting module 30, it can flexibly change its height under the action of the lifting module 30 to meet the needs of shooting objects or scenes at different heights.

[0046] The lifting module 30 is a key component for raising and lowering the second platform 20. It features height adjustment, allowing for precise and stable adjustment of the second platform 20's height according to different shooting scenarios. The lifting module 30 can employ common structures such as a screw-nut drive structure or a sprocket drive structure.

[0047] One component of the lifting module 30 and the second shelf 20 is equipped with a locking structure 31, while the other component is equipped with a locking tongue 21. The locking structure 31 is typically designed as a component with a specific shape and mechanical properties, and its core function is to cooperate with the locking tongue 21 to form a reliable locking connection. Through its internal mechanical structure, such as springs or slots, it can generate sufficient friction and restraint when the locking tongue 21 is inserted, thus tightly locking the locking tongue 21 and preventing the second shelf 20 from accidentally separating from the lifting module 30 during operation. When disassembly is required, specific operations (such as pressing a button or pulling a handle) overcome the resistance inside the locking mechanism, causing the locking mechanism to release the locking tongue 21 and achieving separation between the two.

[0048] The photography-assisted mobile vehicle 100 provided in this embodiment forms a driving connection between the lifting module 30 and the second platform 20 through the locking engagement of the locking tongue 21 and the locking structure 31. When a lifting operation is required, the lifting module 30 is activated, causing the second platform 20 to rise or fall relative to the first platform 10, thereby adjusting the height of the photography equipment and related props on the second platform 20 to meet the needs of different shooting scenarios. When it is necessary to disassemble the second platform 20 and the lifting module 30, simply release the locking connection between the locking tongue 21 and the locking structure 31 to cancel the driving connection and achieve separation of the two.

[0049] Unlike traditional camera support mobile carts where connecting the lifting module 30 and the storage platform requires multiple tools such as wrenches and screwdrivers and involves a complicated operation, the camera support mobile cart 100 of this application achieves a detachable connection through the locking cooperation of the locking tongue 21 and the locking structure 31, making operation simpler and faster. Workers can quickly install and disassemble the second storage platform 20 and the lifting module 30 without tools, greatly saving time and labor costs, and helping to improve the efficiency and quality of the entire film and television shooting project.

[0050] This detachable connection method allows for flexible establishment and cancellation of the drive connection between the second platform 20 and the lifting module 30 during actual shooting, depending on the specific shooting scene and needs, facilitating subsequent operations. For example, establishing the drive connection allows the second platform 20 to be raised and lowered, while canceling the drive connection allows the second platform 20 to be detached or the lifting module 30 to be folded and stored on the second platform 20 (e.g., the lifting module 30 has a foldable design), reducing the size of the photography auxiliary moving vehicle 100 and making it easier to operate in confined spaces.

[0051] Please refer to Figures 1 to 4 In some embodiments, the locking tongue 21 is provided on the lifting module 30;

[0052] The locking structure 31 includes a retaining member 311, a supporting member 312, and a resetting member 313. The retaining member 311 is disposed on the second shelf 20 and has a locking groove 3111 adapted to the locking tongue 21. The supporting member 312 is movably disposed on the second shelf 20 and is used to press against the locking tongue 21 to engage the locking tongue 21 in the locking groove 3111 or to release the locking tongue 21 so that the locking tongue 21 can be disengaged from the locking groove 3111. The resetting member 313 acts on the supporting member 312 and is used to provide a force for the supporting member 312 to reset.

[0053] The main function of the retaining member 311 is to provide precise positioning and accommodating space for the locking tongue 21. By opening a locking groove 3111 that is adapted to the locking tongue 21, the retaining member 311 can guide the locking tongue 21 to be accurately inserted. After the locking tongue 21 is inserted, it works together with the abutment member 312 to firmly lock the locking tongue 21 in the predetermined position, preventing it from shifting or coming out during operation, and ensuring the connection stability between the lifting module 30 and the second platform 20.

[0054] The main function of the abutment 312 is to apply a continuous clamping force to the locking tongue 21 after it is inserted into the locking groove 3111, ensuring that the locking tongue 21 is firmly engaged in the locking groove 3111. When it is necessary to unlock, the abutment 312 can release the clamping force on the locking tongue 21 under external force, allowing the locking tongue 21 to smoothly disengage from the locking groove 3111, thereby separating the lifting module 30 from the second shelf 20.

[0055] The reset member 313 provides a force to the abutment member 312 to reset it, ensuring that the abutment member 312 always maintains the tendency to move towards the bolt 21 when no external force is applied, thereby continuously applying a clamping force to the bolt 21 and maintaining the locked state of the latch structure 31.

[0056] For example, the reset member 313 is typically an elastic element such as a spring, with one end fixed to the retaining member 311 or the second shelf 20, and the other end connected to the abutment member 312. When the abutment member 312 is subjected to an external force and moves away from the locking groove 3111, the reset member 313 is stretched or compressed, storing elastic potential energy; when the external force disappears, the reset member 313 releases the elastic potential energy, pushing the abutment member 312 to move towards the locking groove 3111, returning to the initial position of the blocking groove 311a.

[0057] When it is necessary to connect the lifting module 30 and the second platform 20, the locking tongue 21 located on the lifting module 30 is aligned with the locking groove 3111 of the retaining member 311 on the second platform 20 and inserted. After insertion, the movable abutment 312 slides towards the locking tongue 21 under the continuous force of the reset member 313. After the abutment 312 contacts the locking tongue 21, it applies pressure to the locking tongue 21 by its own structure, tightly locking the locking tongue 21 into the locking groove 3111. At this time, the locking tongue 21, the abutment 312, and the retaining member 311 interact to form a stable connection, enabling the lifting module 30 to safely lift and lower the second platform 20, providing stable support for the photographic equipment.

[0058] When it is necessary to separate the lifting module 30 from the second shelf 20, the operator applies an external force to the holding member 312 that is opposite to the force exerted by the resetting member 313. This external force overcomes the elasticity of the resetting member 313, causing the holding member 312 to move away from the locking tongue 21. As the holding member 312 moves, its clamping force on the locking tongue 21 disappears, and the locking tongue 21 is no longer constrained. At this time, the locking tongue 21 can be easily pulled out of the locking groove 3111, thus separating the two.

[0059] In this embodiment, when the operator connects the lifting module 30 and the second platform 20, they only need to insert the locking tongue 21 into the locking groove 3111. Subsequently, the supporting member 312 and the resetting member 313 automatically complete the locking action, without the need for complicated operations or tools. When unlocking, simply apply force to move the supporting member 312, which greatly shortens the equipment installation and disassembly time.

[0060] In some embodiments, the locking groove 3111 is provided with a slot 311a, which is used for the locking tongue 21 to enter or exit the locking groove 3111 along its sliding direction;

[0061] The retaining member 312 is used to block the slot 311a so that the bolt 21 can be engaged in the locking slot 3111 or to open the slot 311a so that the bolt 21 can be disengaged from the locking slot 3111.

[0062] Among them, the slot 311a serves as the channel 3112 for the latch 21 to enter and exit the locking groove 3111. It is located at one end of the locking groove 3111 and its direction is consistent with the sliding direction of the latch 21. It provides a guiding path for the insertion and removal of the latch 21, greatly improving the convenience of installation.

[0063] During the connection between the lifting module 30 and the second shelf 20, the locking tongue 21 starts from the lifting module 30 and slides smoothly into the locking groove 3111 along the slot 311a of the retaining member 311 on the second shelf 20. After the locking tongue 21 enters the locking groove 3111, the movable abutment member 312 slides towards the slot 311a under the continuous drive of the reset member 313 until it blocks the slot 311a to prevent the locking tongue 21 from exiting from the slot 311a. Together with the inner wall of the locking groove 3111, the locking tongue 21 is firmly restricted in the locking groove 3111, so that the lifting module 30 and the second shelf 20 form a stable connection.

[0064] When it is necessary to separate the lifting module 30 from the second shelf 20, the operator applies an external force to the abutment 312 that is opposite to the force exerted by the reset member 313. After overcoming the elasticity of the reset member 313, the abutment 312 moves away from the slot 311a, allowing the slot 311a to open. With the slot 311a open, the locking tongue 21 is no longer obstructed by the abutment 312, and the operator can easily slide the locking tongue 21 along the slot 311a out of the locking groove 3111, thus separating the two.

[0065] In this embodiment, the slot 311a makes the insertion and withdrawal path of the locking tongue 21 clearer, reducing the difficulty of installation and disassembly. Operators can quickly slide the locking tongue 21 into or out of the locking slot 3111 without repeatedly adjusting its position. Simultaneously, the automatic blocking and opening of the slot 311a by the supporting member 312, combined with its simple operation, greatly improves the efficiency of equipment connection and disconnection.

[0066] Please continue to refer to this. Figure 3 and Figure 4 In some embodiments, the retaining member 311 is provided with a channel 3112, which is located on one side of the locking groove 3111 and is connected to the locking groove 3111.

[0067] The abutment 312 is accommodated in the channel 3112 and slides with the channel 3112. It can enter the locking groove 3111 through the groove side wall of the locking groove 3111 to block the groove opening 311a or exit from the locking groove 3111 to open the groove opening 311a.

[0068] The channel 3112 provides space and path for the abutment 312 to move, allowing it to smoothly enter and exit the locking groove 3111, thereby controlling the opening and closing of the slot 311a. Specifically, the channel 3112 is connected to and located on one side of the locking groove 3111. The abutment 312 slides within the channel 3112. When the abutment 312 enters the locking groove 3111 via the side wall of the groove, it can block the slot 311a, preventing the bolt 21 from exiting. When the abutment 312 exits from the locking groove 3111 and returns to the channel 3112, the slot 311a opens, and the bolt 21 can freely disengage.

[0069] In this embodiment, the retaining member 311 integrates the locking groove 3111 and the channel 3112 into one unit. The supporting member 312 is accommodated in the channel 3112 and can cooperate with the locking groove 3111. This design makes full use of space, enabling the entire locking structure 31 to achieve complex functions within a limited space without occupying too much space. This is beneficial for the miniaturization and lightweight design of equipment such as the photography-assisted mobile vehicle 100. Moreover, the channel 3112 provides a certain degree of protection for the supporting member 312, preventing it from being affected by external interference and damage during movement. This extends the service life of the supporting member 312, reduces maintenance costs, and also ensures the long-term stable operation of the locking structure 31.

[0070] In some embodiments, the abutment 312 has an abutment portion 3121 that can enter or exit the locking groove 3111 and a control portion 3122 that is at least partially exposed outside the channel 3112. The abutment portion 3121 is used to block or open the groove 311a, and the control portion 3122 is used to drive the abutment portion 3121 to move.

[0071] The main function of the abutment part 3121 is to block the opening 311a when it enters the locking groove 3111, preventing the bolt 21 from disengaging from the locking groove 3111 and thus locking the bolt 21. When unlocking is required, it exits the locking groove 3111, opens the opening 311a, and allows the bolt 21 to exit smoothly from the locking groove 3111. The control part 3122 facilitates the operation of the abutment part 312 by the operator. By applying external force to the control part 3122, the abutment part 3121 is moved between the channel 3112 and the locking groove 3111, thereby controlling the locking and unlocking of the bolt 21.

[0072] When the latch 21 needs to be locked, under the action of the reset member 313, the holding part 3121 slides within the channel 3112 and enters the locking groove 3111, blocking the opening 311a. At this time, the latch 21 is restricted within the locking groove 3111 and cannot be dislodged. When unlocking is required, the operator applies external force to the control part 3122 exposed outside the channel 3112, overcoming the force of the reset member 313, causing the holding part 3121 to exit from the locking groove 3111, opening the opening 311a, and allowing the latch 21 to dislodge from the locking groove 3111, completing the unlocking action.

[0073] In this embodiment, the control part 3122 is at least partially exposed outside the channel 3112, allowing the operator to directly access the control part 3122. Without the need for additional tools or complex operating methods, the operator can easily control the abutment 312 to lock and unlock the bolt 21, improving operational convenience and efficiency. Furthermore, the clear distinction between the abutment 3121 and the control part 3122 makes the function of the abutment 312 clearer and the structure more rational. The operator can apply force to the control part 3122 more accurately, thereby more precisely controlling the movement of the abutment 3121 and ensuring that the locking and unlocking actions of the bolt 21 are completed accurately and reliably.

[0074] Please continue to refer to this. Figure 4 In some embodiments, the channel 3112 includes a first sub-channel 311b and a second sub-channel 311c that are connected in a bent manner, and the second sub-channel 311c is connected to the locking groove 3111.

[0075] The abutment member 312 includes a first segment 312a and a second segment 312b that are bent and connected. The first segment 312a is movably disposed in the first sub-channel 311b, and the second segment 312b is movably disposed in the second sub-channel 311c. The abutment part 3121 is constructed at the end of the second segment 312b away from the first segment 312a, and the control part 3122 is constructed at the end of the first segment 312a away from the second segment 312b.

[0076] When it is necessary to lock the latch 21, under the action of the reset member 313, the first segment 312a of the abutment member 312 slides within the first sub-channel 311b, driving the connected second segment 312b to move within the second sub-channel 311c, so that the abutment part 3121 (located at the end of the second segment 312b away from the first segment 312a) enters the locking groove 3111, blocking the groove opening 311a. Because the channel 3112 is bent and connected, this structure guides the abutment member 312 to move along a specific path, ensuring that the abutment part 3121 can accurately reach the predetermined position within the locking groove 3111, thereby locking the latch 21. At this time, the latch 21 is restricted within the locking groove 3111 and cannot disengage from the groove opening 311a, thus completing the locking connection between the lifting module 30 and the second shelf 20.

[0077] When unlocking is required, the operator applies external force to the control unit 3122 (located at the end of the first segment 312a away from the second segment 312b) to overcome the force of the reset member 313. The external force is transmitted through the first segment 312a to the second segment 312b, causing the abutment 3121 to retract from the locking groove 3111 and open the slot 311a. The abutment 312 moves in the opposite direction along the bending path of the first sub-channel 311b and the second sub-channel 311c until the abutment 3121 completely leaves the locking groove 3111, at which point the locking tongue 21 can disengage from the locking groove 3111, thus separating the lifting module 30 from the second shelf 20.

[0078] In this embodiment, the channel 3112 adopts a bent and connected design. The first segment 312a and the second segment 312b of the abutment 312 are adapted to the corresponding sub-channel 3112 and are bent and connected. This structure makes the abutment 312 constrained by the channel 3112 during movement, reducing the possibility of shaking and displacement, and also reducing the possibility of the abutment 312 falling out of the channel 3112. In the locked state, the abutment part 3121 can more stably block the slot 311a, improving the locking effect of the latch 21, enhancing the stability of the entire latch structure 31, and ensuring reliable connection during equipment operation.

[0079] In some embodiments, the reset member 313 is a reset spring, which is housed in the second sub-channel 311c, with one end of the reset spring abutting against the groove sidewall of the second sub-channel 311c and the other end abutting against the second segment 312b.

[0080] The return spring, serving as the return element 313, has a simple structure and low cost. It can stably provide a return force, ensuring that the holding element 312 can automatically return to the locked position without external interference, thus guaranteeing the reliability and stability of the latch structure 31. During the use of the photography-assisted moving vehicle 100, even after prolonged vibration and bumps, the return spring can continue to function, maintaining the locked state of the latch 21.

[0081] In this embodiment, the reset spring is housed in the second sub-channel 311c, making full use of the space inside the channel 3112 without occupying too much extra space, which helps to achieve the miniaturization and lightweight design of the structure.

[0082] In some embodiments, the control part 3122 is annular.

[0083] The ring-shaped control part 3122 of the abutment member 312 is at least partially exposed outside the channel 3112, providing the operator with a clear point of force application. When it is necessary to move the abutment part 3121, the operator can use their fingers or tools to apply pulling or pushing force through the ring. Due to the shape of the ring, the force can be applied evenly to the abutment member 312, allowing the abutment part 3121 to slide smoothly within the channel 3112. When the applied external force overcomes the force of the reset member 313, the abutment part 3121 can retract from the locking groove 3111, opening the slot 311a to unlock; and when the external force disappears, the reset member 313 pushes the abutment part 3121 back into the locking groove 3111 to block the slot 311a, completing the locking.

[0084] In this embodiment, the circular control part 3122 is ergonomically designed, allowing the operator's fingers to naturally wrap around the ring and make full contact with it, increasing friction and preventing slippage. This comfortable operating feel reduces operator fatigue, especially in situations requiring frequent locking and unlocking operations, thus improving work efficiency.

[0085] In addition, the circular control unit 3122 has a distinctive appearance, making it easy for operators to identify and locate. In the complex environment of the shooting location, staff can quickly find and operate the control unit 3122 without spending time searching for or confirming its location, further improving the convenience and efficiency of operation.

[0086] It should be understood that the control unit 3122 can be not only circular, but also square, triangular or irregular in shape, etc., and the embodiments of this application are not limited here.

[0087] Please refer to Figure 1 and Figure 5 In some embodiments, the lifting module 30 includes a drive assembly 32 and a lifting member 33 driven to rise and fall by the drive assembly 32, with the locking tongue 21 fixedly connected to the lifting member 33; and / or,

[0088] The photography-assisted mobile vehicle 100 also includes a guide structure 40, which includes a guide bracket 41 and a guide sleeve 42. The guide bracket 41 extends along the lifting direction of the second platform 20 and is fixed on the first platform 10. The guide sleeve 42 is fixed on the second platform 20 and slides with the guide bracket 41.

[0089] When the drive assembly 32 is working, it outputs power to drive the lifting component 33 to move up and down. Since the locking tongue 21 is fixedly connected to the lifting component 33, the locking tongue 21 moves synchronously with the lifting component 33. The fixed connection between the locking tongue 21 and the lifting component 33 ensures that the locking tongue 21 will not loosen or fall off during the lifting process, so that the locking tongue 21 can stably cooperate with the locking groove 3111, which enhances the stability of the connection between the second platform 20 and the lifting module 30 and provides reliable support for the photography equipment.

[0090] Exemplarily, the drive assembly 32 can adopt a motor lead screw drive structure, while the lifting component 33 is a nut. When the motor runs, the lead screw rotates accordingly, and the nut and lead screw are threaded together. The rotation of the lead screw drives the nut to move linearly along the lead screw axis. The locking tongue 21 is fixed on the nut, and the raising and lowering of the nut drives the locking tongue 21 to rise and fall synchronously, realizing the precise docking of the locking tongue 21 and the locking groove 3111, and stably connecting or separating the second shelf 20. Of course, this is only an example, and the drive assembly 32 can also adopt common structures such as chain drive structure and belt drive structure. This application embodiment does not limit this.

[0091] In this embodiment, the guide bracket 41 extends along the lifting direction of the second platform 20 and is fixed on the first platform 10, serving a guiding function. The guide sleeve 42 is fixed on the second platform 20 and slides in cooperation with the guide bracket 41. When the second platform 20 moves up and down under the drive of the lifting module 30, the guide sleeve 42 slides along the direction of the guide bracket 41. Due to the restriction of the guide bracket 41, the second platform 20 can only move up and down in the vertical direction, ensuring the linearity and stability of its lifting movement and avoiding swaying or deviation during the lifting process.

[0092] In this embodiment, the lifting component 33 is slidably disposed within the guide bracket 41, which provides a clear directional constraint on the movement of the lifting component 33. Taking a motor screw drive structure as an example, the motor drives the screw to rotate, and the nut (i.e., the lifting component 33) that cooperates with the screw moves along the screw axis under the drive of the screw. The guide bracket 41 ensures that the nut can only move linearly in the vertical direction (or the preset lifting direction), avoiding the nut from deviating or rotating during the movement, thereby achieving stable lifting of the lifting component 33.

[0093] In some embodiments, at least two locking structures 31 are provided, spaced apart on the second shelf 20;

[0094] There are at least two locking tongues 21, and each locking tongue 21 is locked in place with a locking structure 31.

[0095] When connecting the second shelf 20 to the lifting module 30, multiple latches 21 engage with corresponding multiple locking structures 31. Each latch 21 inserts into the locking groove 3111 of the retaining member 311 in the corresponding locking structure 31, and then the retaining member 312 blocks the groove 311a under the action of the resetting member 313, locking the latch 21 in the locking groove 3111. Since multiple locking structures 31 are spaced apart on the second shelf 20, the second shelf 20 and the lifting module 30 are connected from multiple positions, forming a stable connection between them.

[0096] In this embodiment, at least two locking structures 31 and locking tongues 21 are provided to connect the second platform 20 and the lifting module 30 from multiple positions. Compared with a single locking structure 31 and locking tongue 21, the connection force can be distributed more evenly, effectively preventing the second platform 20 from tilting, shaking, or loosening during use. Furthermore, the multiple locking structures 31 and locking tongues 21 increase the redundancy of the connection. Even if one locking structure 31 or locking tongue 21 fails, the others can still maintain the connection's effectiveness, reducing the risk of equipment falling or being damaged due to the failure of a single component. This high-safety design can effectively avoid accidents and ensure the safety of equipment and personnel when filming important scenes.

[0097] In actual production, the number and position of the locking structure 31 and the locking tongue 21 can be flexibly adjusted according to the different load requirements, such as the weight and size of the photographic equipment carried by the second platform 20. For heavier or larger equipment, the number of locking structures 31 and locking tongues 21 can be increased to provide sufficient connection force; for lighter equipment, the number can be appropriately reduced to reduce cost and equipment weight while ensuring connection stability.

[0098] In some embodiments, two locking structures 31 are provided, spaced apart on the same side of the second shelf 20 and symmetrically arranged about the centerline in the width direction of the second shelf. The operating parts 3122 of the two locking structures 31 are arranged close to each other. Two locking tongues 21 are provided, and each locking tongue 21 cooperates with one locking structure 31.

[0099] The two locking structures 31 are symmetrically arranged on the same side of the second platform 20. When connected, they can evenly transmit the connecting force from both sides, effectively preventing the second platform 20 from tilting or swaying during use. For example, when the photography auxiliary moving vehicle 100 is moving or the lifting module 30 is working, the symmetrical locking structures 31 can better resist external forces, maintain the balance of the second platform 20, provide stable support for the photography equipment placed on it, and ensure the clarity and stability of the captured images.

[0100] The control parts 3122 of the two locking structures 31 are positioned close together, which greatly facilitates the operation by the operator. The operator can apply force to both control parts 3122 with one hand at the same time, or operate one control part 3122 and then quickly operate the other, without having to move the hand position significantly on the equipment, reducing operation time and effort, and improving the efficiency of installation and disassembly.

[0101] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
