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 film and television production, camera support vehicles (also known as director's vehicles) play a crucial role. Their primary function is to place and move various camera props, greatly facilitating the filming process. With the equipment on board, the director can monitor the footage in real time, adjusting shooting strategies as needed to ensure the content meets expectations. Simultaneously, the vehicle boasts a large storage capacity, accommodating a variety of camera equipment, providing ample and convenient equipment support for the filming process, significantly improving the overall efficiency and smoothness of the shooting workflow.

[0003] Currently, most common photography auxiliary mobile carts are equipped with electric lifting functions. Relying on the coordinated operation of the platform and the lifting module, they can meet the needs of different heights during shooting to a certain extent, bringing convenience to the shooting work. In order to achieve convenient storage and transportation after shooting, some photography auxiliary mobile carts are designed with lifting modules that can rotate flexibly relative to the platform, so as to achieve folding and storage of equipment and improve space utilization efficiency.

[0004] However, this design has introduced new problems. Due to the presence of the rotating structure, the platform is extremely unstable during lifting and lowering. When the lifting module operates, driving the platform to rise or fall, the rotating structure will be displaced or shaken due to the lifting force, making it difficult for the photographic equipment on the platform to maintain a stable state. It may even accidentally slip off during lifting and lowering, causing damage to the equipment and resulting in significant losses to the photographic work. Utility Model Content

[0071] Please refer to Figure 1One embodiment of this application proposes a photography-assisted mobile vehicle 100, including a first platform 10, a second platform 20, a rotating seat 30, a lifting module 40, and a first locking component 50; the second platform 20 and the first platform 10 are arranged opposite each other in a vertical direction; the rotating seat 30 is rotatably connected to the second platform 20; the lifting module 40 is disposed on the first platform 10 and connected to the rotating seat 30, and the lifting module 40 can drive the rotating seat 30 to raise or lower the second platform 20; the first locking component 50 is disposed between the rotating seat 30 and the second platform 20, and the first locking component 50 is used to lock or unlock the rotating seat 30.

[0072] In the locked state, the rotating base 30 is fixed relative to the second shelf 20; in the unlocked state, the rotating base 30 can move relative to the second shelf 20, driving the lifting module 40 to rotate so that the lifting module 40 switches between the unfolded position and the folded position.

[0073] In this embodiment, the first platform 10 serves as one of the basic support structures of the entire photography-assisted mobile vehicle 100. It is mainly used to support the lifting module 40 and provide it with a stable installation position. At the same time, it can also place some relatively heavy or large photography equipment that is not convenient to place on the second platform 20, thus sharing the overall load and ensuring the stability of the center of gravity of the photography-assisted mobile vehicle 100.

[0074] The second shelf 20 is vertically opposite to the first shelf 10 and can hold photographic equipment. Its height can be adjusted by the lifting module 40 to meet the needs of different shooting angles and heights.

[0075] The lifting module 40 is installed on the first platform 10 and connected to the rotating base 30. When the lifting module 40 is activated, it drives the rotating base 30 to control the lifting of the second platform 20. Since the second platform 20 is rotatably connected to the rotating base 30, during the lifting process, the rotating base 30 will drive the second platform 20 to rise or fall vertically.

[0076] The lifting module 40 can be composed of a drive component 421 and a transmission assembly, such as a motor, a lead screw, and a nut. The motor drives the lead screw to rotate, and the nut moves axially along the lead screw, thereby driving the connected components (such as the rotating seat 30 and the second shelf 20) to perform lifting movements. Of course, this is only an example; the lifting module 40 can also adopt common structures such as a sprocket-type lifting structure, and this embodiment of the application is not limited thereto.

[0077] The first locking component 50 plays a crucial role in state switching. When locked, the rotating base 30 is fixed relative to the second platform 20, preventing the rotating base 30 from rotating relative to the second platform 20. This ensures that when the lifting module 40 drives the second platform 20 to rise or fall, the rotating base 30 will not shift or wobble due to the lifting force, thus ensuring the stability of the second platform 20 and the photographic equipment placed on it. When unlocked, the rotating base 30 can move relative to the second platform 20, allowing the lifting module 40 to switch between unfolded and folded positions, meeting the needs of folding and storing the equipment after shooting and maximizing space utilization.

[0078] In this embodiment, the photography-assisted mobile vehicle 100 controls the state of the rotating seat 30 and the second storage platform 20 through the first locking component 50. When locked, the rotating seat 30 is fixed relative to the second storage platform 20, ensuring that the lifting module 40 provides a stable platform for the photography equipment during the lifting and lowering of the second storage platform 20, effectively avoiding the risk of the photography equipment accidentally slipping during lifting and lowering, and greatly ensuring the safety of the equipment. When unlocked, the rotating seat 30 can move relative to the second storage platform 20, driving the lifting module 40 to switch between unfolded and folded positions, which is convenient for storage and transportation and improves space utilization efficiency.

[0079] Please refer to Figures 1 to 4 In some embodiments, the first locking component 50 includes a locking groove 51 and a locking hook 52. The locking groove 51 is disposed on one of the rotating seat 30 and the second shelf 20. The locking hook 52 is movably disposed on the other of the rotating seat 30 and the second shelf 20. The locking hook 52 is used to engage with the locking groove 51 to fix the rotating seat 30 relative to the second shelf 20, or to disengage from the locking groove 51 to allow the rotating seat 30 to rotate relative to the second shelf 20.

[0080] The first locking component 50 operates based on the cooperation between mechanical structures. When the locking hook 52 engages with the locking groove 51, a mechanical connection is formed, restricting the relative rotation between the rotating base 30 and the second shelf 20. At this time, the photography auxiliary moving cart 100 is in a stable locked state and will not be displaced due to rotation, ensuring stability during use. When it is necessary for the rotating base 30 to rotate relative to the second shelf 20, an external force is applied to the locking hook 52, causing it to disengage from the locking groove 51, releasing the constraint on the rotating base 30. The rotating base 30 can then rotate flexibly, facilitating operations such as folding and storage.

[0081] In this embodiment, the first locking component 50 consists of a locking groove 51 and a locking hook 52 as its core parts. Its simple structure, compared to complex locking devices, reduces the overall cost of the photography-assisted mobile vehicle 100 while ensuring functionality. It also facilitates later maintenance and replacement, reducing maintenance costs. Operators can simply hook the locking hook 52 into or out of the locking groove 51 without complex procedures or professional skills, enabling them to quickly complete locking and unlocking actions and improving work efficiency.

[0082] In some embodiments, the first locking component 50 further includes an unlocking member 53 and a first resetting member. The unlocking member 53 is movably disposed on the second shelf 20 and is used to drive the lock hook 52 out of the lock groove 51. The first resetting member acts on the unlocking member 53 and is used to apply a force to the unlocking member 53 to reset it.

[0083] In the first locking assembly 50, the movement of the unlocking element 53 is crucial for the unlocking operation. It can be movably mounted on the second shelf 20 via mechanical connections such as sliding rails and hinged links. When the operator needs to unlock, an external force is applied to the unlocking element 53, causing it to displace according to its predetermined movement path. This displacement is precisely transmitted to the locking hook 52 via mechanical transmission. With sufficient force, the hook 52 overcomes the engagement force between the locking hook 52 and the locking groove 51, thereby disengaging the locking hook 52 from the locking groove 51, releasing the locking constraint on the rotating seat 30, and allowing the rotating seat 30 to rotate freely relative to the second shelf 20.

[0084] The first reset element intervenes after the unlocking action is completed. The first reset element is typically an elastic component, such as a coil spring or rubber sheet, with one end securely connected to the unlocking element 53 and the other end fixed to the second shelf 20. During the unlocking process, the first reset element undergoes elastic deformation due to the displacement of the unlocking element 53, storing elastic potential energy. Once the unlocking operation is complete and the external force removes the unlocking element 53, the first reset element releases its stored elastic potential energy, converting its own restoring force into a reset driving force on the unlocking element 53, pushing it to move in the opposite direction of its unlocking path until it returns to its initial position, preparing for the next locking operation.

[0085] In this embodiment, the design of the unlocking component 53 allows operators to unlock the device in the most intuitive and convenient way, reducing the difficulty of operation and making it easy for even non-professionals to use. Meanwhile, the automatic reset function of the first reset component eliminates the tedious manual repositioning step, improving the smoothness and comfort of operation and meeting the fast-paced, high-efficiency work requirements of the shooting location. The coordinated work of the unlocking component 53 and the first reset component ensures a smooth transition between the locked and unlocked states of the first locking component 50. The first reset component promptly resets the unlocking component 53, preventing accidental locking due to random shaking or contact, further enhancing the stability of the connection between the rotating base 30 and the second platform 20 in the locked state, providing reliable support for the photographic equipment.

[0086] Please refer to Figure 5 and Figure 6 In some embodiments, the second shelf 20 includes a support plate 21 and a bracket 22 connected to the support plate 21 on the side facing the first shelf 10, and a locking groove 51 is provided on the bracket 22.

[0087] The unlocking component 53 is movably inserted through the support plate 21 and aligned with the lock groove 51.

[0088] The unlocking component 53 is inserted through the support plate 21 and aligned with the locking groove 51 on the bracket 22, forming an efficient force transmission path. When an external force is applied to the unlocking component 53, the unlocking component 53, guided by the movable channel on the support plate 21, accurately and centrally transmits the force to the position corresponding to the locking groove 51, thereby overcoming the hooking force between the locking hook 52 and the locking groove 51, allowing the locking hook 52 to smoothly exit from the locking groove 51, and releasing the lock on the rotating seat 30.

[0089] In this embodiment, the unlocking component 53 is inserted through the support plate 21 and partially exposed on the support plate 21. It cleverly utilizes the space between the support plate 21 and the bracket 22, eliminating the need to create additional space to install the unlocking device. This makes the structure of the second shelf 20 compact and reasonable. Moreover, the operator can easily access the unlocking component 53 above the support plate 21, thereby controlling the locking and unlocking of the lock hook 52 and the lock groove 51.

[0090] Furthermore, the support plate 21, serving as the mounting carrier for the unlocking element 53, is designed to form a stable mechanical connection with the bracket 22. When the locking hook 52 is locked with the locking groove 51, the support plate 21, bracket 22, unlocking element 53, and related connecting components together constitute a stable mechanical structure, enhancing the support strength of the entire second platform 20 on the rotating seat 30, reducing stress concentration points caused by additional structures, and enabling the photography auxiliary moving vehicle 100 to maintain better structural integrity when bearing the weight of the photography equipment and vibrations during shooting, thus reducing the risk of equipment damage.

[0091] In some embodiments, the bracket 22 is further provided with an expansion slot 511 communicating with the locking slot 51, and the unlocking member 53 is partially aligned with the expansion slot 511.

[0092] Some tolerances are unavoidable during the manufacturing process, and long-term use of the equipment may also cause slight displacement of components. However, the expansion slot 511 in this embodiment provides additional space for the unlocking component 53 to move, ensuring that even if the unlocking component 53 deviates to a certain extent, it can still interact normally with the locking hook 52 to unlock. This structural fault tolerance greatly improves the reliability of the first locking assembly 50, reduces the probability of unlocking failure due to minor component deviations, lowers the maintenance frequency and repair costs, and ensures stable operation of the photography-assisted mobile vehicle 100 in various environments.

[0093] Please continue to refer to this. Figure 3 In some embodiments, the rotating seat 30 includes a rotating connecting part 31 and a mounting part 32 connected to each other. The rotating connecting part 31 is rotatably connected to the support plate 21. The mounting part 32 extends toward the first shelf 10 on the side opposite to the rotating connecting part 31. The locking hook 52 is provided on the mounting part 32.

[0094] The rotating base 30 forms a rotating pair with the support plate 21 via the rotating connecting part 31 (such as a hinge connection), allowing the rotating base 30 to rotate flexibly relative to the support plate 21, providing a basis for folding and storing the equipment and adjusting different shooting angles. When it is necessary to change the state of the equipment, the rotating base 30 rotates around the rotation axis of the rotating connecting part 31, driving the mounting part 32 connected to it to move together.

[0095] The mounting part 32 extends towards the first shelf 10 from the side opposite to the rotating connection part 31. This extension design allows the mounting part 32 to span a certain space, precisely positioning the locking hook 52 at the position corresponding to the locking groove 51 on the bracket 22. During locking, after the rotating seat 30 rotates to the appropriate position, the locking hook 52, supported by the mounting part 32, can smoothly engage with the locking groove 51 of the bracket 22, achieving a fixed connection between the rotating seat 30 and the second shelf 20. During unlocking, the unlocking member 53 drives the locking hook 52 to disengage from the locking groove 51, and the rotating seat 30 can then freely rotate to the desired position based on the rotational characteristics of the rotating connection part 31.

[0096] The locking hook 52 is installed on the mounting part 32, which can obtain a stable mounting base. When the locking hook 52 engages with the locking groove 51, the mounting part 32 can evenly distribute the force borne by the locking hook 52 to the overall structure of the rotating seat 30, which enhances the stability of locking and can better resist external forces such as vibration and shaking that may occur during shooting, ensuring that the photography equipment remains stable in the locked state.

[0097] In this embodiment, the mounting part 32 extends towards the first shelf 10, cleverly utilizing the internal space of the equipment and avoiding space waste or structural interference caused by unreasonable installation position of the locking hook 52. This layout makes the entire mobile vehicle structure more compact and reasonable, achieving the integration of more functions within a limited space and improving the space utilization efficiency of the equipment.

[0098] Please refer to Figure 7 In some embodiments, the mounting part 32 is provided with a mounting groove 321;

[0099] The locking hook 52 includes a hinge portion 521 and a hook portion 522 that are bent. The hinge portion 521 is located in the mounting groove 321 and is rotatably connected to the mounting portion 32 via a hinge shaft 523. The hook portion 522 is used to form a hook engagement with the locking groove 51 or to cancel the hook engagement.

[0100] The mounting groove 321 in the mounting part 32 provides a precise mounting and positioning space for the hinge part 521 of the lock hook 52. The hinge part 521 of the lock hook 52 is bent and cleverly placed in the mounting groove 321, and is rotatably connected to the mounting part 32 through the hinge shaft 523, allowing the lock hook 52 to rotate flexibly around the hinge shaft 523. When unlocking is required, the unlocking member 53 applies a force to the lock hook 52, overcoming the hooking force between the hook part 522 and the lock groove 51, causing the lock hook 52 to rotate around the hinge shaft 523, the hook part 522 to disengage from the lock groove 51, the hooking engagement is released, and the rotating seat 30 returns to its rotatable state.

[0101] In this embodiment, the mounting groove 321 serves to limit and protect the hinge portion 521, preventing the locking hook 52 from shifting or wobbling during rotation, and ensuring precise engagement between the hook portion 522 and the locking groove 51. Simultaneously, the hinge shaft 523 connects the locking hook 52, allowing the force to be evenly distributed to the mounting portion 32 when subjected to hooking force, thus enhancing the stability of the entire structure.

[0102] Please continue to refer to this. Figure 7 In some embodiments, the mounting part 32 is provided with a limiting groove 322 that communicates with the mounting groove 321;

[0103] The locking hook 52 also includes a limiting part 524 connected to the hinge part 521. The limiting part 524 is used to abut against the groove wall of the limiting groove 322 to fix the hook part 522 relative to the mounting part 32 or to release the abutment against the groove wall of the limiting groove 322 so that the hook part 522 can rotate relative to the mounting part 32.

[0104] The design of the limiting groove 322 communicating with the mounting groove 321 provides the limiting part 524 of the locking hook 52 with both movement space and constraint mechanism. When the hooking part 522 of the locking hook 52 engages with the locking groove 51 on the bracket 22, locking the rotating seat 30 and the second shelf 20, the limiting part 524 will tightly abut against the groove wall of the limiting groove 322. At this time, the abutting force between the limiting part 524 and the groove wall of the limiting groove 322 prevents the locking hook 52 from rotating unexpectedly around the hinge axis 523, thus strengthening the locking state of the locking hook 52 from another dimension and ensuring that the hooking part 522 stably maintains engagement with the locking groove 51. When unlocking is required, the operator applies external force to drive the unlocking component 53, which in turn drives the locking hook 52 to rotate. During this process, the limiting part 524 gradually releases its abutment against the wall of the limiting groove 322, thereby removing the additional restriction on the rotation of the locking hook 52. This allows the locking hook 52 to rotate smoothly around the hinge axis 523, enabling the hook part 522 to disengage from the locking groove 51 and completing the unlocking operation.

[0105] In this embodiment, the abutting cooperation between the limiting part 524 and the groove wall of the limiting groove 322 further prevents the locking hook 52 from loosening or being accidentally unlocked due to external force vibration, bumps and other unexpected situations. This greatly improves the reliability of the photography-assisted mobile vehicle 100 in the locked state and provides a more solid guarantee for the stability of the equipment during the shooting process. It is especially suitable for shooting scenarios in complex road conditions or vibration environments.

[0106] Furthermore, through the cooperation of the limiting part 524 and the limiting groove 322, the rotation of the locking hook 52 is limited to a reasonable range during normal use, reducing wear on the hinge shaft 523, mounting groove 321, and the locking hook 52 itself caused by excessive or accidental rotation. For example, in frequent locking and unlocking operations, without a limiting structure, the locking hook 52 may collide and rub against surrounding components due to excessive rotation angle or loss of direction, accelerating component damage. The existence of the limiting structure effectively avoids such situations, extends the service life of the locking hook 52 and related components, and reduces equipment maintenance costs.

[0107] Please continue to refer to this. Figure 2 and Figure 4 In some embodiments, the second shelf 20 has a first surface 201 facing the first shelf 10 and a second surface 202 facing away from the first shelf 10. The second shelf 20 is provided with a through hole 203 penetrating the first surface 201 and the second surface 202. A rotating seat 30 is located in the through hole 203 and is rotatably connected to the edge of the through hole 203. One end of the rotating seat 30 extends at least partially to the side of the second shelf 20 facing the first shelf 10 and is provided with a locking hook 52.

[0108] The second shelf 20 has a through hole 203 penetrating the first surface 201 and the second surface 202. The rotating seat 30 is placed in the through hole 203, and its edge forms a rotatable connection with the edge of the through hole 203. This connection method forms the basis for the rotation of the rotating seat 30 relative to the second shelf 20. One end of the rotating seat 30 extends at least partially to the side of the second shelf 20 facing the first shelf 10, so that the locking hook 52 installed at this end can precisely interact with the locking groove 51 on the bracket 22. When locking is required, the rotating seat 30 rotates around the rotatable connection point with the edge of the through hole 203 to a suitable position, and the locking hook 52 engages with the locking groove 51, thus fixing the rotating seat 30 to the second shelf 20; when unlocking, the rotating seat 30 rotates in the opposite direction, and the locking hook 52 disengages from the locking groove 51. During this process, the through hole 203 provides space for the rotation of the rotating seat 30, while constraining its rotation trajectory and ensuring the stability of the rotation.

[0109] In this embodiment, the design of the rotating base 30 located within the through hole 203 greatly optimizes the space utilization of the photography-assisted mobile vehicle 100. It eliminates the need for additional complex rotating connection structures on the surface of the second platform 20, allowing full utilization of the upper and lower surface space of the second platform 20. For example, more photography equipment can be placed flat on the second surface 202 of the second platform 20, while the connection between the first surface 201 and the rotating base 30 and related components is compact and orderly. This achieves the integration of more functions within a limited space, improving the overall compactness and rationality of the photography-assisted mobile vehicle 100.

[0110] Please continue to refer to this. Figure 1 In some embodiments, the lifting module 40 includes:

[0111] Mounting bracket 41 is connected to the first shelf 10. Mounting bracket 41 is slidably connected to the rotating seat 30 and can rotate relative to the second shelf 20 with the rotating seat 30.

[0112] The lifting drive assembly 42 is mounted on the mounting bracket 41 and is connected to the rotating seat 30. When the rotating seat 30 is fixed relative to the second shelf 20, the rotating seat 30 drives the second shelf 20 to rise or fall.

[0113] The mounting frame 41 is securely connected to the first platform 10 and slidably connected to the rotating base 30, providing basic support for the lifting and rotation of the rotating base 30. Once the rotating base 30 is fixed relative to the second platform 20 via the first locking assembly 50, the lifting drive assembly 42 begins to function. The lifting drive assembly 42 is mounted on the mounting frame 41 and connected to the rotating base 30 via a mechanical transmission structure (such as a lead screw nut 423 or a chain and sprocket). When the lifting drive assembly 42 is activated, its internal power source (such as a motor) generates power, which is converted into a force acting on the rotating base 30 through the transmission structure. Since the rotating base 30 is fixed to the second platform 20, this force drives the rotating base 30 to move the second platform 20 up or down along the sliding track of the mounting frame 41, thus adjusting the height of the platform of the photography auxiliary mobile vehicle 100.

[0114] In this embodiment, the mounting frame 41's connection to the first platform 10 and its sliding connection to the rotating base 30 provide a stable support structure for the entire lifting process. During lifting, the mounting frame 41 effectively distributes the weight of the rotating base 30 and the second platform 20, reducing swaying and instability caused by center of gravity shift. Even when supporting heavy photographic equipment, it ensures a smooth lifting process, providing a reliable working platform for the shooting equipment.

[0115] In some embodiments, the rotating seat 30 is sleeved on the mounting frame 41, and the mounting frame 41 has guide rails 411 on opposite sides. The rotating seat 30 is connected to the mounting frame 41 by a slider 412 on the guide rail 411 to slide in connection with the mounting frame 41.

[0116] When the lifting drive assembly 42 operates, the power it generates is transmitted to the rotating seat 30. Since the rotating seat 30 is fixedly connected to the slider 412, and the slider 412 can slide on the guide rail 411, the power is converted into linear motion of the rotating seat 30 along the direction of the guide rail 411. In this process, the guide rail 411 plays a guiding role, constraining the slider 412 and the rotating seat 30 to slide only along a predetermined linear direction, ensuring the accuracy of the lifting motion of the rotating seat 30. At the same time, the design of the rotating seat 30 being fitted onto the mounting bracket 41 allows the rotating seat 30 to rotate stably around its own axis with the mounting bracket 41 as the center, without affecting its sliding connection with the guide rail 411-slider 412 system. When the first locking component 50 is unlocked, the rotating seat 30 can rotate relative to the second shelf 20, causing the mounting bracket 41 and the guide rail 411 to rotate together, thus meeting the needs of multi-angle adjustment of the equipment. After the first locking component 50 is locked, the rotating seat 30 is fixed to the second shelf 20, and the lifting drive component 42 drives the rotating seat 30 to rise and fall along the guide rail 411, thereby adjusting the height of the second shelf 20.

[0117] In this embodiment, the cooperation between the guide rail 411 and the slider 412 has high precision, which can effectively reduce the swaying and offset of the rotating seat 30 during the lifting process. The slider 412 slides smoothly on the guide rail 411, making the lifting process of the rotating seat 30 driving the second platform 20 more stable and precise. Moreover, the rotating seat 30 is sleeved on the mounting frame 41, and the connection between the guide rails 411 on both sides and the slider 412 forms a stable mechanical structure. During the lifting process, the guide rails 411 on both sides of the mounting frame 41 can evenly distribute the weight of the rotating seat 30 and the second platform 20, enhancing the rigidity of the entire structure, improving the stability of the lifting movement of the rotating seat 30, and providing reliable support for the photographic equipment.

[0118] Please refer to Figure 8 In some embodiments, the lifting drive assembly 42 includes a drive member 421, a screw 422, and a nut 423. The drive member 421 is mounted on the mounting frame 41 or the first platform 10. The screw 422 is rotatably mounted on the mounting frame 41 and is connected to the output end of the drive member 421. The nut 423 is threadedly engaged with the screw 422, and the rotating seat 30 is connected to the nut 423.

[0119] The drive unit 421 drives the screw 422 to rotate, thereby causing the nut 423 to move up and down along the axial direction of the screw 422, which in turn causes the second platform 20 to rise or fall relative to the first platform 10.

[0120] The driving component 421 (such as a motor) serves as the power source. When the driving component 421 is started, its output end begins to operate, transmitting power to the screw 422 through a transmission device (such as a belt or gear), causing the screw 422 to rotate around its own axis. Since the nut 423 and the screw 422 are engaged by threads, according to the principle of threaded transmission, when the screw 422 rotates, the nut 423 will be subjected to the force of the threads, thus moving linearly along the axial direction of the screw 422. Furthermore, because the second platform 20 is connected to the nut 423, the lifting and lowering movement of the nut 423 will drive the second platform 20 to rise or fall relative to the first platform 10 through the rotating seat 30, realizing the vertical position adjustment of the second platform 20 to meet the needs of different shooting heights during photography.

[0121] In this embodiment, the lifting drive assembly 42 mainly consists of a drive component 421, a screw 422, and a nut 423. Its structure is relatively simple, with fewer parts, reducing the probability of malfunctions caused by an excessive number of components. Simultaneously, the threaded connection between the screw 422 and the nut 423 has high stability and reliability, capable of withstanding a certain load. During the use of the photography-assisted mobile vehicle 100, it ensures the smooth lifting of the second platform 20, preventing shaking or jamming.

[0122] In some embodiments, the drive unit 421 is mounted on the side of the first shelf 10 facing away from the second shelf 20;

[0123] The first shelf 10 is provided with a through hole 101. One end of the screw 422 extends through the through hole 101 to the side of the first shelf 10 facing away from the second shelf 20, and is connected to the drive member 421 through the transmission mechanism 424.

[0124] The screw 422 is connected to the drive component 421 through the through hole 101, and the transmission mechanism 424 is used for transmission. This ensures the stability and accuracy of power transmission, makes the rotation of the screw 422 more stable, and drives the second platform 20 to rise and fall smoothly, reducing shaking and vibration, and improving the reliability and safety of the lifting process.

[0125] In this embodiment, the drive unit 421 is installed on the side of the first shelf 10 facing away from the second shelf 20, which avoids occupying space between the first shelf 10 and the second shelf 20, making the overall structure more compact. This is beneficial for realizing the lifting function in a limited space, and also makes it convenient to place items on the first shelf 10 without being interfered with by the drive unit 421.

[0126] For example, the transmission mechanism 424 may include a transmission rod, one end of which is connected to the output end of the drive member 421, and the other end of the transmission rod is provided with a first helical gear. One end of the screw 422 is provided with a second helical gear. The first helical gear and the second helical gear can be meshed to transmit the rotational power of the drive member 421 to the screw 422, thereby driving the nut 423 on the screw 422 to move.

[0127] Please refer to Figure 1 In some embodiments, the photography-assisted mobile vehicle 100 further includes an auxiliary lifting module 60, which is disposed on the first platform 10 and spaced apart from the lifting module 40. The output end of the auxiliary lifting module 60 is connected to the second platform 20 to provide support for the second platform 20 and to drive the second platform 20 to rise or fall relative to the first platform 10.

[0128] In this embodiment, the photography-assisted mobile vehicle 100 is equipped with an auxiliary lifting module 60, which is horizontally spaced from the mounting frame 41. Its output end is connected to the second platform 20, supporting and driving the lifting of the second platform 20. Its working principle is based on the coordinated operation of the auxiliary lifting module 60 and the lifting module 40, enhancing the stability and load-bearing capacity of the lifting function. The auxiliary lifting module 60 has an output end that can abut against the second platform 20, providing additional support points. Together with the lifting drive assembly 42 of the mounting frame 41, it shares the weight of the second platform 20 and the photographic equipment on it. The horizontal spacing increases the support distribution range. When the second platform 20 carries heavy equipment, the auxiliary lifting module 60 shares the load of the lifting module 40, reducing the stress on components such as the screw 422.

[0129] The auxiliary lifting module 60 can move the second platform 20 closer to or further away from the first platform 10, and move synchronously with the lifting module 40. For example, when the screw 422 is driven to rotate, the output end of the auxiliary lifting module 60 moves simultaneously, pushing the second platform 20 to move in the same direction; conversely, it retracts synchronously when lowering.

[0130] In some embodiments, the auxiliary lifting module 60 may have an independent drive source (e.g., a hydraulic pump or a motor), but its operation is coordinated with the lifting module 40 to ensure the smooth lifting and lowering of the second platform 20.

[0131] Please refer to Figure 1 and Figure 9 In some embodiments, the auxiliary lifting module 60 includes a housing 61, a lifting chain 62, and a power assembly 63. The housing 61 is connected to the first platform 10. The lifting chain 62 is vertically mounted on the housing 61 and connected to the second platform 20. The power assembly 63 is located on the first platform 10 and is connected to the lifting chain 62 for driving the lifting chain 62 to rise or fall.

[0132] When the photography assistance moving vehicle 100 needs to adjust the height of the second platform 20, the power unit 63 is activated. Since the power unit 63 is connected to the lifting chain 62, it transmits its own power to the lifting chain 62. The pulling or pushing force generated by the operation of the power unit 63 causes the lifting chain 62 to move up and down along a predetermined track within the housing 61. Because the lifting chain 62 is connected to the second platform 20, the raising and lowering of the lifting chain 62 directly moves the second platform 20 closer to or further away from the first platform 10, thereby adjusting the height of the second platform 20. Simultaneously, the housing 61 acts as a guide and protector during this process, ensuring that the lifting chain 62 moves along a stable path and preventing it from deviating or swaying during raising and lowering.

[0133] In this embodiment, the housing 61 is relatively small in size and will not occupy too much extra space after being connected to the first platform 10. The lifting chain 62 can be stored inside the housing 61, making the overall structure of the photography-assisted mobile vehicle 100 more compact without affecting the lifting function. This is especially suitable for shooting scenarios with limited space, such as small indoor spaces or occasions where frequent movement of equipment is required. Moreover, the housing 61 provides a stable track for the lifting chain 62, effectively limiting the direction of movement of the lifting chain 62 and reducing the risk of it deviating or derailing during lifting.

[0134] The lifting chain 62 has high strength and toughness, and can withstand large tensile forces. When sharing the weight of the second platform 20 and photographic equipment, it can operate stably even when carrying heavy equipment, ensuring the safety of lifting and lowering the second platform 20, and greatly expanding the load range of the photographic auxiliary mobile vehicle 100.

[0135] In the design of the photography-assisted mobile vehicle 100, in order to simplify the structure and improve the system integration, the drive component 421 of the lifting module 40 can be used as the power component 63 of the auxiliary lifting module 60. That is to say, one drive component 421 can drive two modules to work together to meet the different lifting requirements of the second platform 20.

[0136] In this design architecture, the screw 422 of the lifting module 40 and the lifting chain 62 of the auxiliary lifting module 60 are both connected to the same drive unit 421. When the drive unit 421 is activated, its output power is synchronously transmitted to the lifting module 40 and the auxiliary lifting module 60 through a specific transmission mechanism 424.

[0137] During the rising phase of the second platform 20, the drive unit 421 drives the screw 422 to rotate. Due to the threaded action, the nut 423 rises along the axial direction of the screw 422, thereby raising the second platform 20 via the rotating seat 30. Simultaneously, power is transmitted via a transmission device to the auxiliary lifting module 60, driving the lifting chain 62 to move upwards within the housing 61, providing additional lifting force to the second platform 20. This collaborative working mode not only shares the load pressure of a single module but also allows the second platform 20 to maintain high stability during the rising process, preventing tilting or swaying.

[0138] During the descent of the second platform 20, the drive unit 421 controls the screw 422 to rotate in the opposite direction, and the nut 423 drives the second platform 20 to descend slowly. On the auxiliary lifting module 60 side, the lifting chain 62 descends synchronously, working closely with the lifting module 40 to ensure the smooth descent of the second platform 20.

[0139] This shared power component 63 design offers numerous advantages. Firstly, it significantly reduces the number of parts in the equipment, lowering overall manufacturing and maintenance costs. Secondly, it simplifies system complexity, improves equipment reliability and stability, and reduces potential failure points caused by multiple power sources. Simultaneously, by optimizing the transmission mechanism 424 and control system, the two modules can work in a highly coordinated manner, greatly enhancing the lifting performance and working efficiency of the photography-assisted mobile vehicle 100, providing more stable and efficient equipment support for photography operations.

[0140] Please refer to Figure 1 In some embodiments, the photography-assisted mobile vehicle 100 further includes a second locking component 70 disposed between the first platform 10 and the lifting module 40. The second locking component 70 is used to lock or unlock the lifting module 40. In the locked state, the lifting module 40 is connected to the first platform 10. In the unlocked state, the lifting module 40 can be separated from the first platform 10.

[0141] When in operation, the second locking component 70 securely fixes the lifting module 40 to the first platform 10 via mechanical structures (such as clips, bolts, etc.), keeping the lifting module 40 in a fixed state relative to the first platform 10 and ensuring the stability of the equipment during shooting. When maintenance, replacement, or adjustment of the lifting module 40 is required, the second locking component 70 is operated to unlock it. At this time, the connection between the lifting module 40 and the first platform 10 is released, and the lifting module 40 can be separated from the first platform 10 for subsequent operations.

[0142] In this embodiment, since the lifting module 40 and the first platform 10 are detachably connected and the connection status is controlled by the second locking component 70, when the lifting module 40 malfunctions or needs maintenance, the lifting module 40 can be disassembled separately by simply unlocking the second locking component 70. Unlike the traditional photography auxiliary mobile vehicle 100, which requires replacing the entire lifting module 40 along with the platform, this greatly reduces maintenance costs and difficulties, saves maintenance time, and improves the efficiency of equipment use.

[0143] During use, the second locking component 70 ensures the stability of the lifting module 40, providing reliable support for photography. When adjustments to the equipment structure or operations on the lifting module 40 are needed, it can be easily unlocked, allowing for separation and reinstallation of the lifting module 40. This meets the needs of different operating scenarios, making the photography-assisted mobile vehicle 100 more flexible and convenient to use.

[0144] Please refer to Figure 10 and Figure 11In some embodiments, the second locking component 70 includes a lock hole 71 provided in the lifting module 40 and a lock tongue 72 and a drive mechanism 73 provided in the first shelf 10.

[0145] The drive mechanism 73 is connected to the locking tongue 72 and is used to drive the locking tongue 72 to insert into the lock hole 71 to lock the lifting module 40, or to drive the locking tongue 72 to exit from the lock hole 71 to unlock the lifting module 40.

[0146] The second locking assembly 70 mainly consists of a lock hole 71 on the lifting module 40, a locking tongue 72 on the first shelf 10, and a drive mechanism 73. The drive mechanism 73 is the power source for the entire second locking assembly 70 and is connected to the locking tongue 72. When it is necessary to lock the lifting module 40, the drive mechanism 73 is activated, transmitting power to the locking tongue 72 through a transmission device. This causes the locking tongue 72 to move towards the lock hole 71 and insert into the lock hole 71, thereby fixing the lifting module 40 to the first shelf 10 and locking the lifting module 40. At this time, the lifting module 40 cannot move relative to the first shelf 10. When it is necessary to unlock, the drive mechanism 73 operates in reverse, driving the locking tongue 72 to exit from the lock hole 71, releasing the locking connection between the lifting module 40 and the first shelf 10, allowing the lifting module 40 to be separated from the first shelf 10 for maintenance, replacement, or adjustment.

[0147] In this embodiment, the insertion and withdrawal of the locking tongue 72 are controlled by the drive mechanism 73. The locking and unlocking of the lifting module 40 can be achieved simply by operating the drive mechanism 73, without the need for a complicated disassembly process, thus improving the operating efficiency.

[0148] The locking mechanism, where the latch 72 inserts into the lock hole 71, provides a relatively stable connection, ensuring that the lifting module 40 will not be accidentally unlocked due to external vibrations or other factors during the use of the photography assistance mobile cart 100. This guarantees the stability and safety of the equipment, thereby ensuring the smooth progress of shooting operations. Furthermore, the combination of the lock hole 71 and the latch 72 is relatively simple and compact, occupying minimal space and contributing to the overall simplicity and portability of the photography assistance mobile cart 100, facilitating equipment transport and storage.

[0149] It should be noted that the drive mechanism 73, as a key component of the second locking assembly 70 of the photography-aided moving vehicle 100, can be divided into two types: manual and electric. The manual drive mechanism 73 relies on components such as knobs and handles, which are manually rotated or operated by the operator to drive the transmission components, causing the locking tongue 72 to insert or retract into the locking hole 71. This method is low-cost, not limited by power supply, and intuitive to operate. The electric drive mechanism 73 consists of a motor, controller, and transmission components. After receiving a command, the motor drives the locking tongue 72 to move, making it convenient, efficient, highly automated, and precise. The choice between these two types of drive mechanisms 73 can be made in actual use, and this application does not impose any limitations on their selection.

[0150] Please refer to Figure 10 and Figure 11 In some embodiments, the drive mechanism 73 includes a slide 731, a control component 732, and a second reset component 733. The slide 731 is located on the side of the first shelf 10 facing the second shelf 20 and is slidably connected to the first shelf 10. The locking tongue 72 is connected to the slide 731. The control component 732 is connected to the slide 731 and is used to drive the slide 731 to slide so that the locking tongue 72 can be inserted into or withdrawn from the lock hole 71. The second reset component 733 acts on the slide 731 and is used to apply a force to the slide 731 to reset it.

[0151] The slide block 731 plays a crucial role in connecting and transmitting motion. It is installed on the side of the first platform 10 facing the second platform 20 and is slidably connected to the first platform 10, serving as the moving carrier for the locking tongue 72. In the initial state, when the control component 732 applies force, the slide block 731 slides in a specific direction, causing the locking tongue 72 to insert into the lock hole 71, thus locking the lifting module 40.

[0152] The control component 732 is the interaction part between the operator and the drive mechanism 73. Its function is to translate the operator's operating intentions into actual mechanical movements. It can apply force to the slide 731, drive the slide 731 to slide, thereby causing the locking tongue 72 to move as needed.

[0153] The second reset member 733 mainly functions after the locking tongue 72 is inserted into the lock hole 71. After the control component 732 completes the insertion of the locking tongue 72, the second reset member 733 starts to work, applying force to the slide block 731, thereby providing continuous pressure to the locking tongue 72, so that the locking tongue 72 is firmly embedded in the lock hole 71, enhancing the reliability of locking, ensuring that the lifting module 40 can maintain the locked state in various environments, and also helping to maintain the overall stability of the equipment.

[0154] This embodiment's drive mechanism 73, composed of a slide 731, a control component 732, and a second reset component 733, has a relatively simple overall structure. It lacks complex transmission components and precision control elements, reducing the probability of malfunctions, improving the mechanism's reliability, and lowering maintenance costs. Furthermore, the presence of the second reset component 733 not only saves operators time and effort in manually resetting the device but also ensures that the equipment returns to its initial state after each operation, improving the consistency and stability of the equipment's state and laying a reliable foundation for the next locking or unlocking operation.

[0155] 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.
