[0074] Please refer to Figure 1 One embodiment of this application proposes a photography-assisted mobile vehicle 100, including a first platform 10, a second platform 20, and a first locking structure 40; the second platform 20 and the first platform 10 are arranged opposite each other in the vertical direction; a lifting module 30 is detachably arranged on the first platform 10 and connected to the second platform 20, the lifting module 30 supports the second platform 20 and can drive the second platform 20 to rise or fall relative to the first platform 10;

[0075] The first locking structure 40 is located between the first shelf 10 and the lifting module 30. The first locking structure 40 is used to lock or unlock the lifting module 30. In the locked state, the lifting module 30 is connected to the first shelf 10. In the unlocked state, the lifting module 30 can be separated from the first shelf 10.

[0076] The photography-aided mobile vehicle 100 mainly consists of a first storage platform 10, a second storage platform 20, a lifting module 30, and a first locking structure 40. The first storage platform 10 serves as the basic support component, providing stable bottom support for the entire device. The second storage platform 20 is vertically opposite to the first storage platform 10 and is used to place photographic equipment and other items. The lifting module 30 plays a crucial role in connecting the first storage platform 10 and the second storage platform 20. It is detachably mounted on the first storage platform 10 and simultaneously connected to the second storage platform 20, enabling the second storage platform 20 to move vertically. The first locking structure 40 controls the connection state between the lifting module 30 and the first storage platform 10.

[0077] The lifting module 30, through its own mechanical structure (such as common lifting structures like lead screws and hydraulic systems), drives the second platform 20 to rise or fall relative to the first platform 10 after receiving power (such as electric drive), so that the second platform 20 can be flexibly adjusted between different heights to adapt to the diverse needs of shooting height during the photography process.

[0078] When in operation, the first locking structure 40 securely fixes the lifting module 30 to the first platform 10 via mechanical means (such as clips, bolts, etc.), keeping the lifting module 30 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 30 is required, the first locking structure 40 is operated to unlock it. At this time, the connection between the lifting module 30 and the first platform 10 is released, and the lifting module 30 can be separated from the first platform 10 for subsequent operations.

[0079] In this embodiment, since the lifting module 30 and the first platform 10 are detachably connected and the connection status is controlled by the first locking structure 40, when the lifting module 30 malfunctions or needs maintenance, the lifting module 30 can be disassembled separately by simply unlocking the first locking structure 40. Unlike traditional photography auxiliary mobile vehicles, the entire lifting module and platform need to be replaced together, which greatly reduces maintenance costs and difficulties, saves maintenance time, and improves the efficiency of equipment use.

[0080] During use, the first locking structure 40 ensures the stability of the lifting module 30, providing reliable support for photography. When adjustments to the equipment structure or operations on the lifting module 30 are needed, it can be easily unlocked, allowing for separation and reinstallation of the lifting module 30. This meets the needs of different operating scenarios, making the photography-assisted mobile vehicle 100 more flexible and convenient to use.

[0081] Please refer to Figure 2 In some embodiments, the first locking structure 40 includes a lock hole 41 provided in the lifting module 30, a lock tongue 42 provided in the first shelf 10, and a drive mechanism 43.

[0082] The drive mechanism 43 is connected to the locking tongue 42 for driving the locking tongue 42 to insert into the lock hole 41 to lock the lifting module 30, or to drive the locking tongue 42 to exit from the lock hole 41 to unlock the lifting module 30.

[0083] The first locking structure 40 mainly consists of a lock hole 41 on the lifting module 30, a locking tongue 42 on the first shelf 10, and a drive mechanism 43. The drive mechanism 43 is the power source for the entire first locking structure 40, and it is connected to the locking tongue 42. When it is necessary to lock the lifting module 30, the drive mechanism 43 is activated, transmitting power to the locking tongue 42 through a transmission device, causing the locking tongue 42 to move towards the lock hole 41 and insert into the lock hole 41, thereby fixing the lifting module 30 to the first shelf 10 and locking the lifting module 30. At this time, the lifting module 30 cannot move relative to the first shelf 10. When it is necessary to unlock, the drive mechanism 43 operates in reverse, driving the locking tongue 42 to exit from the lock hole 41, releasing the locking connection between the lifting module 30 and the first shelf 10, allowing the lifting module 30 to be separated from the first shelf 10 for maintenance, replacement, or adjustment.

[0084] In this embodiment, the insertion and withdrawal of the locking tongue 42 are controlled by the drive mechanism 43. The locking and unlocking of the lifting module 30 can be achieved simply by operating the drive mechanism 43, without the need for a complicated disassembly process, thus improving the operating efficiency.

[0085] The locking mechanism of the latch 42 inserting into the lock hole 41 provides a relatively stable connection, ensuring that the lifting module 30 will not be accidentally unlocked due to external vibration 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. Moreover, the combination structure of the lock hole 41 and the latch 42 is relatively simple and compact, without occupying too much space. This helps maintain the simplicity and portability of the overall structure of the photography assistance mobile cart 100, facilitating the transportation and storage of the equipment.

[0086] It should be noted that the drive mechanism 43, as a key component of the first locking structure 40 of the photography-assisted moving vehicle 100, can be divided into two types: manual and electric. The manual drive mechanism 43 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 42 to insert or retract into the locking hole 41. This method is low-cost, not limited by power supply, and intuitive to operate. The electric drive mechanism 43 consists of a motor, controller, and transmission components. After receiving a command, the motor drives the locking tongue 42 to move, making it convenient, efficient, highly automated, and precise. The choice between these two types of drive mechanisms 43 can be made in actual use, and this application does not impose any limitations on their selection.

[0087] Please refer to Figures 2 to 4In some embodiments, the drive mechanism 43 includes a slide 431, a control component 432, and a reset component 433. The slide 431 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 42 is connected to the slide 431. The control component 432 is connected to the slide 431 and is used to drive the slide 431 to slide so that the locking tongue 42 can be inserted into or withdrawn from the lock hole 41. The reset component 433 acts on the slide 431 and is used to apply a force to the slide 431 to reset it.

[0088] The slide block 431 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 42. In the initial state, when the control component 432 applies force, the slide block 431 slides in a specific direction, causing the locking tongue 42 to insert into the lock hole 41, thus locking the lifting module 30.

[0089] The control component 432 is the interaction part between the operator and the drive mechanism 43. Its function is to translate the operator's operating intention into actual mechanical movement. It can apply force to the slide 431, drive the slide 431 to slide, thereby causing the locking tongue 42 to move as needed.

[0090] The reset component 433 mainly functions after the latch 42 is inserted into the lock hole 41. After the control component 432 completes the insertion of the latch 42, the reset component 433 starts to work, applying force to the slide 431, thereby providing continuous pressure to the latch 42, so that the latch 42 is firmly embedded in the lock hole 41, enhancing the reliability of locking, ensuring that the lifting module 30 can maintain the locked state in various environments, and also helping to maintain the overall stability of the equipment.

[0091] This embodiment features a drive mechanism 43 composed of a slide 431, a control component 432, and a reset component 433. The overall structure is relatively simple, lacking complex transmission parts and precision control elements, thus reducing the probability of malfunctions, improving the reliability of the mechanism, and lowering maintenance costs. Furthermore, the presence of the reset component 433 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.

[0092] Please refer to Figures 5 to 8 In some embodiments, the slide 431 is provided with a stop groove 4311;

[0093] The control component 432 includes a support 4321 and a rotating pusher 4322. The support 4321 is disposed on the first shelf 10. The rotating pusher 4322 is rotatably connected to the support 4321. The rotating pusher 4322 is constructed with a push rod 4323. The push rod 4323 is housed in a stop groove 4311 so that the slide 431 and the rotating pusher 4322 form a linkage. The rotating pusher 4322 is used to drive the push rod 4323 to rotate so as to push the slide 431 to slide.

[0094] The support 4321 is fixed to the first platform 10, providing a stable pivot point for the rotating push frame 4322. This ensures that the rotating push frame 4322 will not shift or shake when it rotates around it, thus guaranteeing the stability of the entire control assembly 432. This allows the force applied by the operator to be accurately and effectively transmitted to the rotating push frame 4322, which in turn pushes the slide 431 to drive the locking tongue 42 to perform corresponding actions.

[0095] The rotating pusher 4322 is rotatably connected to the support 4321 and is the direct operating component for the operator to control the drive mechanism 43. When the operator applies external force to the rotating pusher 4322, the rotating pusher 4322 begins to rotate around the support 4321. The push rod 4323 on the rotating pusher 4322 rotates together with the rotating pusher 4322. Since the push rod 4323 is housed in the stop groove 4311 of the slide 431, the circular motion generated by the rotation of the push rod 4323 is converted into the linear motion of the slide 431 through the stop groove 4311. This ingenious design efficiently converts the rotational force applied by the operator into the translational force of the slide 431 along the first platform 10, thereby driving the latch 42 connected to it to perform the corresponding insertion or withdrawal action of the lock hole 41.

[0096] In this embodiment, the cooperative design of the stop groove 4311 and the push rod 4323 achieves efficient power transmission. The rotation of the rotating push frame 4322 can be accurately and directly converted into the linear motion of the slide 431 without too many complex transmission links, reducing energy loss and the probability of mechanical failure. This allows the drive mechanism 43 to respond quickly during operation, enabling it to quickly complete locking and unlocking actions, thus improving the utilization efficiency of the photography-assisted mobile vehicle 100.

[0097] The design of the rotating pusher 4322 allows the operator to flexibly control the magnitude and direction of the applied force according to actual needs, and precisely control the movement of the slide 431 and the locking tongue 42, so as to meet the diverse requirements of the drive mechanism 43 operation in different shooting scenarios.

[0098] In some embodiments, the first shelf 10 is provided with a fixed seat 11, and a guide rail 111 is connected to the fixed seat 11. The slide 431 is connected to the fixed seat 11 by a slider 112 on the guide rail 111.

[0099] The fixed base 11 on the first platform 10 serves to support and position the guide rail 111. The guide rail 111 is securely connected to the fixed base 11, providing a precise guiding path for the movement of the slide 431. The slide 431 is connected to the slider 112 on the guide rail 111, and by utilizing the sliding characteristics of the slider 112 on the guide rail 111, the slide 431 achieves linear movement along the direction of the guide rail 111. This design ensures that the slide 431 is always constrained by the guide rail 111 during movement, and can only slide along the direction determined by the guide rail 111, effectively preventing the slide 431 from deviating or wobbling during movement, and ensuring the movement accuracy of the latch 42 during insertion or withdrawal from the lock hole 41.

[0100] When the control component 432 drives the rotating pusher 4322, thereby pushing the slide 431 to move, the slider 112 acts as an intermediate medium, smoothly transmitting the force applied to the slide 431 by the push rod 4323 to the guide rail 111. Simultaneously, the guide rail 111 and the slider 112 jointly bear the weight of the slide 431 and the locking tongue 42, providing stable support for their movement. When the reset component 433 pushes the slide 431 to slide in the opposite direction, this is also achieved through the sliding of the slider 112 on the guide rail 111, ensuring the smoothness and stability of the entire movement process.

[0101] In some embodiments, a first receiving groove 113 is provided on the side of the fixed base 11 facing the slide 431, and a second receiving groove 4312 is provided on the side of the slide 431 facing the fixed base 11, with the opening of the second receiving groove 4312 aligned with the opening of the first receiving groove 113.

[0102] The reset element 433 is a reset spring. One end of the reset spring is housed in the first receiving groove 113 and abuts against the fixed seat 11. The other end of the reset spring is housed in the second receiving groove 4312 and abuts against the slide 431.

[0103] The first receiving groove 113 and the second receiving groove 4312 not only provide installation space for the return spring, but also serve to position and stabilize the spring. During the operation of the return spring, the first receiving groove 113 restricts the position of one end of the spring, preventing it from moving freely on the fixed seat 11; the second receiving groove 4312 constrains the position of the other end of the spring on the slide 431. In this way, the return spring always maintains its predetermined position and direction during compression and extension, ensuring the stable and accurate transmission of the return force, and avoiding poor return effect or abnormal force affecting the normal movement of the slide 431 and the locking tongue 42 due to spring deviation.

[0104] In this embodiment, the stable installation of the return spring within the receiving groove ensures that it can always provide a stable and consistent reset force during operation. Whether the equipment is used frequently or left idle for extended periods, the return spring maintains good elasticity and reset performance, accurately pushing the slide 431 back to its initial position. This guarantees the reliability and repeatability of each unlocking and reset operation of the drive mechanism 43, providing stable and reliable equipment support for photographic work.

[0105] Please continue to refer to this. Figure 1 and Figure 2 In some embodiments, the lifting module 30 includes a mounting frame 31 and a lifting drive assembly 32 disposed on the mounting frame 31. The mounting frame 31 is detachably connected to the first shelf 10 and is provided with a lock hole 41. The lifting drive assembly 32 is connected to the second shelf 20 and is used to drive the second shelf 20 to rise or fall relative to the first shelf 10.

[0106] The mounting bracket 31 serves as the connecting hub between the lifting module 30 and the first platform 10, and is fixed to the first platform 10 via a detachable connection method (such as a snap-fit ​​connection). This detachable design allows the mounting bracket 31 to be easily separated from the first platform 10 when maintenance, replacement, or adjustment of the lifting module 30 is required. The locking hole 41 on the mounting bracket 31 engages with the locking tongue 42 on the first platform 10. When the locking tongue 42 is inserted into the locking hole 41, the mounting bracket 31 is securely locked to the first platform 10, ensuring the stability of the entire module during lifting.

[0107] The lifting drive assembly 32, mounted on the mounting bracket 31, is the power source for raising and lowering the second platform 20. Common lifting drive assemblies 32 include lead screw and nut mechanisms, hydraulic lifting mechanisms, or electric push rods 4323. Taking the lead screw and nut mechanism as an example, the motor drives the lead screw to rotate, and the nut that cooperates with the lead screw drives the second platform 20 connected to it to rise or fall vertically. By controlling the forward and reverse rotation and speed of the motor, the lifting height and speed of the second platform 20 can be precisely controlled to meet the diverse shooting height requirements of different shooting scenarios.

[0108] Please continue to refer to this. Figure 3 and Figure 6 In some embodiments, the latch 42 is located on the opposite side of the first shelf 10 from the second shelf 20;

[0109] The mounting bracket 31 has a locking part 311, and the locking part 311 has a locking hole 41.

[0110] The first shelf 10 has a first surface 101 facing the second shelf 20 and a second surface 102 facing away from the second shelf 20. The first shelf 10 is provided with a first through hole 103 and a second through hole 104 penetrating the first surface 101 and the second surface 102.

[0111] The slide block 431 is at least partially connected to the latch 42 through the second through hole 104, and the locking part 311 extends through the first through hole 103 to the other side of the first shelf 10 facing away from the second shelf 20, so that the lock hole 41 and the latch 42 are aligned.

[0112] The slide 431 is at least partially connected to the latch 42 through the second through hole 104, allowing the slide 431 and latch 42 located on both sides of the first shelf 10 to establish a connection. The slide 431 can move within the second through hole 104, thereby actuating the latch 42. The locking part 311 constructed on the mounting bracket 31 passes through the first through hole 103 of the first shelf 10, which extends through the first surface 101 and the second surface 102 of the first shelf 10. When the locking part 311 extends to the side of the first shelf 10 opposite to the second shelf 20, the locking hole 41 on the locking part 311 aligns with the latch 42 located on that side. At this time, the latch 42 is moved by the control component 432, causing it to insert into the locking hole 41, thereby securely locking the mounting bracket 31 onto the first shelf 10. In this process, the first through hole 103 plays the role of guiding the position of the locking part 311, ensuring that the locking hole 41 and the locking tongue 42 can be accurately aligned, achieving a stable locking connection, and providing a guarantee for the stable operation of the lifting module 30.

[0113] When maintenance or replacement of the lifting module 30 is required, i.e., when unlocking is needed, the locking tongue 42 is disengaged from the locking hole 41 by the control component 432. After unlocking, since there is no longer the constraint of the locking tongue 42 between the locking part 311 and the first through hole 103, the mounting bracket 31 can move relative to the first shelf 10, pulling the locking part 311 out of the first through hole 103, thereby separating the mounting bracket 31 from the first shelf 10, facilitating subsequent operations on the lifting module 30.

[0114] In this embodiment, the locking tongue 42 is located on the other side of the first platform 10 away from the second platform 20. During normal shooting, the operator is less likely to accidentally touch the locking tongue 42, which reduces the risk of unlocking due to accidental contact and causing the lifting module 30 to move unexpectedly, thus ensuring the stability of the equipment and the safety of the operator during shooting.

[0115] Please continue to refer to this. Figure 4 and Figure 5In some embodiments, the first shelf 10 is further provided with a clamping plate 12, which is disposed opposite to the slide 431, and a clamping space 13 for accommodating the mounting bracket 31 is formed between the slide 431 and the clamping plate 12.

[0116] The slide block 431 can slide toward the clamping plate 12 to cooperate with the clamping plate 12 to clamp the mounting bracket 31, or slide away from the clamping plate 12 to release the mounting bracket 31.

[0117] When it is necessary to fix the mounting bracket 31, the control component 432 drives the slide 431 to slide in the direction opposite to the clamping plate 12. The slide 431 and the clamping plate 12 are arranged opposite each other, and a clamping space 13 for accommodating the mounting bracket 31 is originally constructed between them. As the slide 431 slides, the distance between the slide 431 and the clamping plate 12 gradually decreases, and the mounting bracket 31 is clamped between them. At this time, under the combined action of the slide 431 and the clamping plate 12, the mounting bracket 31 is firmly clamped in the clamping space 13, thereby further stabilizing the connection between the mounting bracket 31 and the first platform 10, and providing additional protection for the stability of the lifting module 30 during operation.

[0118] When it is necessary to disassemble or adjust the mounting bracket 31, the control component 432 operates in reverse, driving the slide 431 to slide away from the clamping plate 12. As the slide 431 moves, the distance between the slide 431 and the clamping plate 12 increases, and the clamping force on the mounting bracket 31 gradually decreases until the mounting bracket 31 can be easily removed from the clamping space 13, thus releasing the mounting bracket 31 and facilitating subsequent maintenance, replacement, or reinstallation of the lifting module 30.

[0119] In this embodiment, the slide block 431 and the clamping plate 12 cooperate to clamp the mounting frame 31, providing an additional fixing method for the mounting frame 31. Compared with relying solely on the connection between the locking tongue 42 and the locking hole 41, this clamping structure can constrain the mounting frame 31 in multiple directions, effectively preventing the mounting frame 31 from shaking or shifting on the first platform 10. Especially when the photography auxiliary moving vehicle 100 moves or is subjected to external impact, it greatly enhances the overall stability of the lifting module 30, ensuring the smooth operation of the equipment during shooting.

[0120] In some embodiments, at least two mounting brackets 31 are provided, each mounting bracket 31 is provided with a locking part 311, and each locking part 311 is configured with a lock hole 41;

[0121] There are at least two locking tongues 42, and each locking tongue 42 is engaged with a locking hole 41.

[0122] In this embodiment, multiple mounting brackets 31 are respectively disposed on the first shelf 10. Each mounting bracket 31 is equipped with a locking part 311, and the locking part 311 has a corresponding lock hole 41. Simultaneously, the first shelf 10 is provided with at least two locking tongues 42 in matching numbers. When fixing the mounting brackets 31, the locking parts 311 of each mounting bracket 31 extend through the corresponding first through holes 103 on the first shelf 10 to the side facing away from the second shelf 20, ensuring accurate alignment between each lock hole 41 and the corresponding locking tongue 42. Subsequently, the control component 432 drives each locking tongue 42 to insert into the corresponding lock hole 41, thereby firmly locking each mounting bracket 31 onto the first shelf 10. This one-to-one insertion and engagement of the locking tongue 42 and lock hole 41 achieves a stable and independent connection between the multiple mounting brackets 31 and the first shelf 10.

[0123] During the operation of the lifting module 30, multiple mounting brackets 31 jointly bear the weight of the second platform 20 and photographic equipment. Since each mounting bracket 31 is connected to the locking hole 41 via an independent locking tongue 42, they can work together to evenly distribute the load from above. When the equipment is subjected to external forces, such as vibration or tilting during movement, each mounting bracket 31 can exert a reaction force on the first platform 10 through its respective connection point, cooperating to maintain the stability of the overall structure and ensuring the normal operation of the lifting module 30, thus guaranteeing the smooth lifting and lowering of the second platform 20.

[0124] Compared to the connection method of a single mounting bracket and locking tongue, in this embodiment, multiple mounting brackets 31 are connected to the lock hole 41 through their respective locking tongues 42, which greatly increases the number of connection points between the mounting brackets 31 and the first platform 10. This multi-connection-point design can more effectively distribute the various forces that the equipment is subjected to during use, including gravity, the impact force generated by vibration, and the lateral force generated by the tilt of the equipment. When the photography assistance mobile vehicle 100 is traveling on bumpy roads or performing complex shooting actions, the multiple mounting brackets 31 and locking tongues 42 work together to significantly enhance the stability of the connection between the entire lifting module 30 and the first platform 10, effectively reducing the risk of displacement, deformation, or even damage to the equipment due to uneven force, and providing more reliable equipment support for shooting work.

[0125] Please refer to Figures 1 to 3 In some embodiments, the lifting drive assembly 32 includes a drive member 321, a screw 322 and a nut 323, and is mounted on the mounting frame 31 or the first shelf; the screw 322 is rotatably mounted on the mounting frame 31 and is connected to the output end of the drive member 321; the nut 323 is threadedly engaged with the screw 322, and the second shelf is connected to the nut 323.

[0126] The drive unit 321 drives the screw 322 to rotate, thereby causing the nut 323 to move up and down along the axial direction of the screw 322, which in turn causes the second platform 20 to rise or fall relative to the first platform 10.

[0127] The driving component 321 (such as a motor) serves as the power source. When the driving component 321 is started, its output end begins to operate, transmitting power to the screw 322 via a transmission device (such as a belt or gear), causing the screw 322 to rotate around its own axis. Since the nut 323 and the screw 322 are threaded together, according to the principle of threaded transmission, when the screw 322 rotates, the nut 323 experiences a threaded force, thus moving linearly along the axial direction of the screw 322. Furthermore, because the second platform 20 is connected to the nut 323, the lifting and lowering movement of the nut 323 causes the second platform 20 to rise or fall relative to the first platform 10, achieving vertical position adjustment of the second platform 20 to meet the needs of different shooting heights during photography.

[0128] In this embodiment, the lifting drive assembly 32 mainly consists of a drive component 321, a screw 322, and a nut 323. 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 322 and the nut 323 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.

[0129] In some embodiments, the drive unit 321 is mounted on the side of the first shelf 10 facing away from the second shelf 20;

[0130] The first shelf 10 is provided with a third through hole 105. One end of the screw 322 extends through the third through hole 105 to the side of the first shelf 10 facing away from the second shelf 20, and is connected to the drive member 321 through the transmission mechanism 324.

[0131] The screw 322 is connected to the drive component 321 through the third through hole 105, and the transmission mechanism 324 is used for transmission. This ensures the stability and accuracy of power transmission, makes the rotation of the screw 322 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.

[0132] In this embodiment, the drive unit 321 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 321.

[0133] For example, the transmission mechanism 324 may include a transmission rod, one end of which is connected to the output end of the drive member 321, and the other end of the transmission rod is provided with a first helical gear. One end of the screw 322 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 321 to the screw 322, thereby driving the nut 323 on the screw 322 to move.

[0134] Please refer to Figure 1 In some embodiments, the photography-assisted mobile vehicle 100 further includes an auxiliary lifting module 50, which is disposed on the first platform 10 and spaced apart from the lifting module 30. The output end of the auxiliary lifting module 50 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.

[0135] In this embodiment, the photography-assisted mobile vehicle 100 is equipped with an auxiliary lifting module 50, which is horizontally spaced from the mounting frame 31. 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 50 and the lifting module 30, enhancing the stability and load-bearing capacity of the lifting function. The auxiliary lifting module 50 has an output end that can abut against the second platform 20, providing additional support points. Together with the lifting drive assembly 32 of the mounting frame 31, it shares the weight of the second platform 20 and the photographic equipment on it. The horizontal spacing increases the distribution range of support. When the second platform 20 carries heavy equipment, the auxiliary lifting module 50 shares the load of the lifting module 30, reducing the stress on components such as the screw 322.

[0136] The auxiliary lifting module 50 can move the second platform 20 closer to or further away from the first platform 10, and move synchronously with the lifting module 30. For example, when the screw 322 is driven to rotate, the output end of the auxiliary lifting module 50 moves simultaneously, pushing the second platform 20 to move in the same direction; conversely, it retracts synchronously when lowering.

[0137] In some embodiments, the auxiliary lifting module 50 may have an independent drive source (e.g., a hydraulic pump or a motor), but its operation is coordinated with the lifting module 30 to ensure the smooth lifting and lowering of the second platform 20.

[0138] Please refer to Figure 1 and Figure 9 In some embodiments, the auxiliary lifting module 50 includes a housing 51, a lifting chain 52, and a power assembly 53. The housing 51 is connected to the first platform 10. The lifting chain 52 is vertically mounted on the housing 51 and connected to the second platform 20. The power assembly 53 is located on the first platform 10 and is connected to the lifting chain 52 for driving the lifting chain 52 to rise or fall.

[0139] When the photography assistance moving vehicle 100 needs to adjust the height of the second platform 20, the power unit 53 is activated. Since the power unit 53 is connected to the lifting chain 52, it transmits its own power to the lifting chain 52. The pulling or pushing force generated by the operation of the power unit 53 causes the lifting chain 52 to move up and down along a predetermined track within the housing 51. Because the lifting chain 52 is connected to the second platform 20, the raising and lowering of the lifting chain 52 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 51 acts as a guide and protector during this process, ensuring that the lifting chain 52 moves along a stable path and preventing it from deviating or swaying during raising and lowering.

[0140] In this embodiment, the housing 51 is relatively small in size and will not occupy too much extra space after being connected to the first platform 10. The lifting chain 52 can be stored inside the housing 51, making the overall structure of the photography auxiliary 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 51 provides a stable track for the lifting chain 52, effectively limiting the direction of movement of the lifting chain 52 and reducing the risk of it deviating or derailing during lifting.

[0141] The lifting chain 52 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 the second platform 20 and greatly expanding the load range of the photographic auxiliary mobile vehicle 100.

[0142] In the design of the photography-assisted mobile vehicle 100, in order to simplify the structure and improve the system integration, the drive component 321 of the lifting module 30 can be used as the power component 53 of the auxiliary lifting module 50. That is to say, one drive component 321 can drive two modules to work together to meet the different lifting requirements of the second platform 20.

[0143] In this design architecture, the screw 322 of the lifting module 30 and the lifting chain 52 of the auxiliary lifting module 50 are both connected to the same drive unit 321. When the drive unit 321 is activated, its output power is synchronously transmitted to the lifting module 30 and the auxiliary lifting module 50 through a specific transmission mechanism 324.

[0144] During the rising phase of the second platform 20, the drive unit 321 drives the screw 322 to rotate. Due to the threaded action, the nut 323 rises along the axial direction of the screw 322, thereby raising the second platform 20. Simultaneously, power is transmitted via a transmission device to the auxiliary lifting module 50, driving the lifting chain 52 to move upwards within the housing 51, 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.

[0145] During the descent of the second platform 20, the drive unit 321 controls the screw 322 to rotate in the opposite direction, and the nut 323 drives the second platform 20 to descend slowly. On the auxiliary lifting module 50 side, the lifting chain 52 descends synchronously, working closely with the lifting module 30 to ensure the smooth descent of the second platform 20.

[0146] This shared power component 53 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 324 and control system, the two modules can work in close coordination, greatly enhancing the lifting performance and operational efficiency of the photography-assisted mobile vehicle 100, providing more stable and efficient equipment support for photography operations.

[0147] Please refer to Figure 1 , Figure 10 and Figure 11 In some embodiments, the photography-assisted mobile vehicle 100 further includes a rotating seat 60 and a second locking structure 70, the second locking structure 70 being rotatably connected to the second platform 20, and a lifting module 30 being connected to the rotating seat 60, the lifting module 30 being able to drive the rotating seat 60 to raise or lower the second platform 20.

[0148] The second locking structure 70 is located between the rotating seat 60 and the second shelf 20. The second locking structure 70 is used to lock or unlock the rotating seat 60.

[0149] In the locked state, the rotating base 60 is fixed relative to the second shelf 20; in the unlocked state, the rotating base 60 can move relative to the second shelf 20, driving the lifting module 30 to rotate so that the lifting module 30 can switch between the unfolded position and the folded position.

[0150] The lifting module 30 is installed on the first shelf 10 and connected to the rotating base 60. When the lifting module 30 is activated, it drives the rotating base 60 to control the lifting of the second shelf 2020. Since the second shelf 20 is rotatably connected to the rotating base 60, during the lifting process, the rotating base 60 will drive the second shelf 20 to rise or fall vertically.

[0151] The second locking structure 70 plays a crucial role in state switching. When locked, the rotating base 60 is fixed relative to the second platform 20, preventing the rotating base 60 from rotating relative to the platform 20. This ensures that when the lifting module 30 drives the second platform 20 to rise or fall, the rotating base 60 will not shift or wobble due to the lifting force, thus guaranteeing the stability of the second platform 20 and the photographic equipment placed on it. When unlocked, the rotating base 60 can move relative to the second platform 20, allowing the lifting module 30 to switch between unfolded and folded positions, meeting the needs of folding and storing the equipment after shooting and maximizing space utilization.

[0152] In this embodiment, the photography-assisted mobile vehicle 100 controls the state of the rotating seat 60 and the second storage platform 20 through the second locking structure 70. When locked, the rotating seat 60 is fixed relative to the second storage platform 20, ensuring that the lifting module 30 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 60 can move relative to the second storage platform 20, driving the lifting module 30 to switch between unfolded and folded positions, which is convenient for storage and transportation and improves space utilization efficiency.

[0153] Please refer to Figure 11 In some embodiments, the second locking structure 70 includes a locking groove 71, a locking hook 72, and an unlocking member 73. The locking groove 71 is disposed on one of the rotating seat 60 and the second shelf 20. The locking hook 72 is movably disposed on the other of the rotating seat 60 and the second shelf 20. The locking hook 72 is used to engage with the locking groove 71 to fix the rotating seat 60 relative to the second shelf 20, or to disengage from the locking groove 71 to allow the rotating seat 60 to rotate relative to the second shelf 20. The unlocking member 73 is movably disposed on the second shelf 20 and is used to drive the locking hook 72 out of the locking groove 71.

[0154] The second locking structure 70 operates based on the cooperation between mechanical structures. When the locking hook 72 engages with the locking groove 71, a mechanical connection is formed, restricting the relative rotation between the rotating seat 60 and the second shelf 20. At this time, the photography auxiliary moving carriage 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 seat 60 to rotate relative to the second shelf 20, an external force is applied to the locking hook 72, causing it to disengage from the locking groove 71, releasing the constraint on the rotating seat 60. The rotating seat 60 can then rotate flexibly, facilitating folding and storage operations.

[0155] The movement of the unlocking component 73 is crucial to 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 component 73, causing it to displace according to its predetermined movement path. This displacement is precisely transmitted to the locking hook 72 through mechanical transmission. With sufficient force, the hook 72 overcomes the engagement force between the locking hook 72 and the locking groove 71, thereby disengaging the locking hook 72 from the locking groove 71, releasing the locking restraint on the rotating seat 60, and allowing the rotating seat 60 to rotate freely relative to the second shelf 20.

[0156] In this embodiment, the second locking structure 70 consists of a locking groove 71 and a locking hook 72 as its core components. Its simple structure, compared to more complex locking devices, reduces the overall cost of the photography-assisted mobile vehicle 100 while maintaining functionality. It also facilitates later maintenance and replacement, reducing maintenance costs. Operators can simply hook the locking hook 72 into or pull it out of the locking groove 71, without requiring complex procedures or professional skills, enabling them to quickly complete locking and unlocking actions and improving work efficiency. Furthermore, the design of the unlocking component 73 allows operators to unlock in the most intuitive and convenient way, reducing operational difficulty and making it easy for even non-professionals to use.

[0157] 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.
