Description

Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and particularly to a photographic auxiliary mobile vehicle and a storage method thereof. Background Art

[0002] In the field of film and television shooting, a photographic auxiliary mobile vehicle (also known as a director's vehicle), as an important mobile carrier, is usually used to place photographic equipment, such as cameras, matte boxes, tripods, spare batteries, etc., providing sufficient and convenient equipment support for the shooting process. Its function integration and portability directly affect the shooting efficiency.

[0003] In related technologies, a photographic auxiliary mobile vehicle with an automatic lifting function usually adopts a rigid drive module such as a lead screw or a hydraulic rod as the lifting structure of the placement platform, and drives the telescopic movement of the lead screw nut pair or the hydraulic cylinder through a motor to achieve the vertical lifting of the platform.

[0004] However, the drive module structure is relatively complex and occupies a large space. After shooting, even when the platform descends to the lowest position, the drive module still occupies the vertical space, resulting in difficulty in compressing the overall height of the vehicle body. It is difficult to achieve good storage in the non-working state, especially in a shooting site with limited space or during transportation, and this problem is particularly prominent, seriously affecting the storage convenience of the vehicle.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0093] In view of the deficiencies in the related technologies pointed out in the background art, the embodiments of the present invention propose a photography auxiliary mobile vehicle that is convenient for storage, improving the performance and practicality of the photography auxiliary mobile vehicle in actual shooting applications. Among them, the photography auxiliary mobile vehicle involved in this embodiment is not limited to the name of the photography auxiliary mobile vehicle, and appellations such as the director vehicle and the camera dolly are also applicable.

[0094] Refer to Figure 1 and Figure 2 , the photography auxiliary mobile vehicle includes:

[0095] The first storage platform 100;

[0096] The second storage platform 200, which is disposed opposite to the first storage platform 100 in the vertical direction;

[0097] The lifting module 300, which is detachably disposed on the first storage platform 100 and connected to the second storage platform 200. The lifting module 300 can rotate relative to the second storage platform 200 for horizontal folding or vertical unfolding;

[0098] The lifting chain module 400, which is disposed on the first storage platform 100 and arranged at an interval from the lifting module 300. The lifting chain module 400 is connected to the second storage platform 200;

[0099] Among them, the lifting module 300 and the lifting chain module 400 support the second storage platform 200 and can drive the second storage platform 200 to move up or down relative to the first storage platform 100.

[0100] Specifically, the photography assistant mobile vehicle mainly includes the first storage platform 100, the second storage platform 200, the lifting module 300 and the lifting chain module 400. The first storage platform 100 serves as the basic bearing platform of the entire photography assistant mobile vehicle, and is used to place some photography props and install other key components. In the vertical direction (the vertical direction of the mobile vehicle walking surface), the second storage platform 200 is disposed opposite to the first storage platform 100, and can be used to place different types of photographic equipment, and cooperate with the first storage platform 100 to increase the storage space of the vehicle. Among them, the first storage platform 100 and the second storage platform 200 can adopt structural forms such as frames, cabinets, boxes, etc., and are constructed with accommodation spaces for accommodating photography props / equipment. And, the first storage platform 100 is located below the second storage platform 200, and the second storage platform 200 is located above the first storage platform 100. In terms of their positional relationship, the first storage platform 100 can also be called the lower storage platform, and the second storage platform 200 can be called the upper storage platform.

[0101] The lifting module 300 is disposed above the first storage table 100 and connected to the second storage table 200. Among them, the lifting module 300 and the first storage table 100 are detachably connected, and the detachable connection form can include snap connection, buckle connection, etc., which is set according to actual needs. For example, a buckle structure is provided between the lifting module 300 and the first storage table 100, and the buckle structure can lock or unlock the lifting module 300. When the lifting module 300 is vertically installed on the first storage table 100, the lifting module 300 can be locked through the buckle structure so that the lifting module 300 is fixed on the first storage table 100. Or, the lifting module 300 can be unlocked through the buckle structure so that the lifting module 300 can be detached from the first storage table 100. This is only exemplary and not restrictive. The lifting module 300 and the second storage table 200 can be rotatably connected, and the lifting module 300 can rotate relative to the second storage table 200 with the rotating structure, and switch between the vertical state and the horizontal state; or, it can also be detachably connected, and the lifting module 300 and the second storage table 200 are split to be able to rotate relative to the second storage table 200, and switch between the vertical state and the horizontal state. The detachable connection method can refer to the foregoing example content and will not be repeated here. Whether it is a rotatable connection or a detachable connection, the lifting module 300 can rotate relative to the second storage table 200 to be vertically unfolded, which is convenient for the normal use of the vehicle. And when the vehicle is to be stored, the lifting module 300 can rotate relative to the second storage table 200 to be horizontally folded. That is, when the vehicle needs to be used, the lifting module 300 is vertically unfolded and cooperates with the first storage table 100 and the second storage table 200 to realize the lifting function of the second storage table 200; when the vehicle needs to be stored, the lifting module 300 can be horizontally folded to reduce the occupied space. Among them, the lifting module 300 can adopt a structural module that can realize linear drive such as a lead screw, a synchronous belt, a hydraulic cylinder, a linear motor, etc., which is selected according to actual needs, and this embodiment does not limit this. And the number of the lifting modules 300 can be set to one or more, which is set according to actual needs. For example, when the lifting module 300 is set to one, in the front-rear direction of the photography-assisted mobile vehicle (defined with reference to the forward and backward directions of the vehicle), the lifting module 300 is located at the front side position of the first storage table 100 (or it can also be the second storage table 200); or, when the lifting module 300 is set to two, in the front-rear direction of the photography-assisted mobile vehicle, one lifting module 300 is located at the front side position of the first storage table 100 (or it can also be the second storage table 200), and the other lifting module 300 is located at the rear side position of the first storage table 100 (or it can also be the second storage table 200). When the vehicle is to be stored, after the two lifting modules 300 are horizontally folded, they can be stacked along the height direction of the photography-assisted mobile vehicle, or can be placed side by side along the left-right direction of the photography-assisted mobile vehicle, and this is not limited.

[0102] The lifting chain module 400 works in cooperation with the lifting module 300 to jointly support the second storage table 200 and drive it to move up or down relative to the first storage table 100, realizing flexible adjustment of the height of the storage table. Among them, the lifting chain module 400 is a driving module mainly composed of a chain, which drives the second storage table 200 to move up and down by controlling the change of the extended length of the chain. Among them, only one lifting chain module 400 can be set. For example, in the front-back direction of the photographic auxiliary mobile vehicle, the lifting module 300 is located at the front side position of the first storage table 100 (or it can also be the second storage table 200), and the lifting chain module 400 is located at the rear side position of the first storage table 100 (or it can also be the second storage table 200); more than one can also be set, such as two. In the front-back direction of the photographic auxiliary mobile vehicle, the lifting module 300 is located at the front side position of the first storage table 100 (or it can also be the second storage table 200). In the left-right direction of the photographic auxiliary mobile vehicle, one lifting chain module 400 is located at the left side position of the first storage table 100 (or it can also be the second storage table 200), and the other lifting chain module 400 is located at the right side position of the first storage table 100 (or it can also be the second storage table 200), which is set according to actual needs.

[0103] Among them, the lifting module 300 and the lifting chain module 400 can each come with a driving part to output driving power to drive the corresponding module to operate when adjusting the height of the storage table; or, the vehicle is configured with a driving module corresponding to the lifting module 300 and the lifting chain module 400. The driving module is arranged on the first storage table 100 and is drivingly connected to the lifting module 300 and the lifting chain module 400. As a power output source, the driving module is used to drive the lifting module 300 and the lifting chain module 400 to operate and provide power support for the lifting of the second storage table 200. The driving module can include a driving motor and a transmission device. The output shaft of the driving motor is connected to the transmission device, and the transmission device is respectively connected to the lifting module 300 and the lifting chain module 400. The transmission device can adopt components such as gears, belts, and transmission rods. When the driving motor operates, power is transmitted to the lifting module 300 and the lifting chain module 400 through the transmission device, so that the lifting module 300 and the lifting chain module 400 operate.

[0104] The working principle of this photographic auxiliary mobile vehicle:

[0105] When the vehicle is working, the lifting module 300 and the lifting chain module 400 act simultaneously. Taking the lead screw as an example of the lifting module 300, when it is necessary to raise the second storage table 200, the driving motor starts, and drives the rotation of the lead screw of the lead screw through the transmission device. Since the nut seat on the lead screw is connected to the second storage table 200, the nut seat moves upward along the lead screw under the rotation of the lead screw, thereby driving the second storage table 200 to rise. At the same time, under the drive of the motor, the chain of the lifting chain module 400 starts to drive. The lifting chain module 400 provides auxiliary support force for the second storage table 200 through the elongation of the chain to ensure the stability of the second storage table 200 during the rising process. The descending process is the opposite. The driving motor rotates in reverse, the lead screw of the lead screw rotates in the reverse direction, the nut seat drives the second storage table 200 to descend, and the chain of the lifting chain module 400 shortens synchronously to provide auxiliary support for the descending process of the second storage table 200.

[0106] If other types of lifting modules 300 are adopted, such as synchronous belts, hydraulic cylinders or linear motors, etc., their working principles are similar. They all transfer power to the corresponding transmission structure through the driving device to realize the rise or fall of the second storage table 200, and at the same time, the lifting chain module 400 works together to ensure the stability of the lifting process.

[0107] When the vehicle needs to be stored, first, through the action of the lifting module 300 and the lifting chain module 400, the second storage table 200 is lowered to the lowest position and overlapped with the first storage table 100. At this time, the height of the vehicle is initially reduced. Then, the lifting module 300 is disassembled and separated from the first storage table 100, and then the lifting module 300 is rotated relative to the second storage table 200 to change it from the vertical unfolded state to the horizontal folded state. At this time, the occupied space of the entire photography auxiliary mobile vehicle is greatly reduced, and the storage process is completed.

[0108] When the vehicle needs to be used, first, the lifting module 300 in the horizontal folded state is rotated relative to the second storage table 200 to restore it to the vertical unfolded state. Then, the lifting module 300 is assembled and connected to the first storage table 100. Finally, through the simultaneous action of the lifting module 300 and the lifting chain, the second storage table 200 is raised to the required height, and the vehicle enters the working state.

[0109] In this embodiment, through the collaborative design of the modular lifting structure and the lifting chain, the photography-assisted mobile vehicle can achieve the rapid disassembly and folding storage of the lifting module 300 while ensuring the load-bearing capacity, significantly improving the space utilization rate. Exemplarily, in a certain film and television shooting site, when using the photography-assisted mobile vehicle of this embodiment, during the shooting process, according to different shooting angles and scene requirements, the second placement table 200 is adjusted to an appropriate height through the lifting module 300 and the lifting chain module 400, and various types of shots are successfully completed. After the shooting is completed, following the storage steps, first lower the second placement table 200 to the lowest position and stack it with the first placement table 100, then disassemble and separate the lifting module 300 and place it horizontally for folding, achieving flat storage. The photography-assisted mobile vehicle that originally occupied a large space has a significantly reduced volume after storage and can be easily placed in the corner of the shooting site without affecting the activities of other equipment and personnel. For another example, when transporting the photography-assisted mobile vehicle of the present invention, due to its convenient storage characteristics, multiple photography-assisted mobile vehicles can be loaded simultaneously within the limited space of the transport vehicle, improving the transport efficiency and reducing the transport cost.

[0110] In some embodiments, the lifting module 300 includes a mounting frame 310 and a lifting drive assembly 320 disposed on the mounting frame 310. The mounting frame 310 is detachably connected to the first placement table 100, and the lifting drive assembly 320 is connected to the second placement table 200.

[0111] Among them, the mounting frame 310 is a frame structure with a certain height, used to set other structural components of the lifting module 300 such as the lifting drive assembly 320. The lifting module 300 is detachably connected to the first placement table 100 through its mounting frame 310, so as to be detachably disposed on the first placement table 100. Specifically, the bottom of the mounting frame 310 is butted against the first placement table 100 and is detachably connected to the first placement table 100. The detachable connection method can adopt snap connection, lock connection, etc. exemplified in the foregoing embodiments. Moreover, the entire mounting frame 310 can be disposed through the second placement table 200, or can also be disposed at the outer side position of the second placement table 200.

[0112] The lifting drive assembly 320 is disposed on the mounting frame 310 and connected to the second storage table 200, and its function is to drive the second storage table 200 to rise or fall. Among them, the structural type of the lifting drive assembly 320 can be various. For example, the lifting drive assembly 320 includes a lead screw. The screw rod of the lead screw is rotatably disposed on the mounting frame 310, and the nut seat on the screw rod is connected to the second storage table 200. When the lead screw is driven by a motor to operate, the screw rod rotates accordingly, and the nut seat moves on the screw rod, thereby driving the second storage table 200 to move to rise or fall. Among them, the motor involved can be directly fixedly disposed on the mounting frame 310 to be connected to the screw rod of the lead screw, or the motor can also be mounted on the second storage table 200 and connected to the screw rod of the lead screw through an intermediate transmission structure (such as a transmission rod, bevel gear assembly, etc.).

[0113] In some embodiments, referring to Figures 3 to 5 , the first storage table 100 has a mounting position, the mounting frame 310 is placed on the mounting position, and a first locking module 510 is provided at the mounting position. The first locking module 510 is used to lock or unlock the mounting frame 310.

[0114] As an important part of the lifting module 300, after the mounting frame 310 is connected to the first storage table 100 through the first locking module 510, the lifting module 300 is stably disposed on the first storage table 100. Specifically, the mounting position provided on the first storage table 100 is adapted to the mounting frame 310 for placing the mounting frame 310. When the mounting frame 310 is placed on the mounting position, the mounting frame 310 can be locked by the first locking module 510 to realize the assembly of the mounting frame 310 and the first storage table 100. The lifting structure of the entire camera-assisted moving vehicle forms a stable whole, which can bear the weight of the photographic equipment and external forces such as vibrations that may occur during shooting; when the first locking module 510 unlocks the mounting frame 310, the lifting module 300 can be disassembled and folded from the first storage table 100, and combined with the storage design of other structures of the vehicle, the efficient storage of the vehicle can be realized.

[0115] The first locking module 510 may be abutted or clamped to lock the mounting frame 310; and when the first locking module 510 loosens the mounting frame 310, the mounting frame 310 is unlocked accordingly. For example, the first locking module 510 includes two clamping arms arranged at a relative interval and respectively connected with elastic elements, and a clamping space for clamping the mounting frame 310 is formed between the two clamping arms. During assembly, the mounting frame 310 is accommodated between the two clamping arms, and under the action of the elastic elements, the two clamping arms clamp the mounting frame 310 from opposite sides of the mounting frame 310, so that the mounting frame 310 is in a locked state. During disassembly, an external force is applied to the two clamping arms (such as prying the two clamping arms apart) so that the two clamping arms loosen the mounting frame 310 in opposite directions, so that the mounting frame 310 is switched from a locked state to an unlocked state, so that the mounting frame 310 is detached from the first storage platform 100.

[0116] In addition, the mounting frame 310 may be configured with a locking structure that cooperates with the first locking module 510 to lock, and the first locking module 510 locks or unlocks the mounting frame 310 by cooperating with the locking structure on the mounting frame 310 .

[0117] Specifically, in some embodiments, referring to Figure 6 and Figure 7 The mounting frame 310 is provided with a locking opening 310K, and the locking opening 310K is used to lock and cooperate with the first locking module 510 to complete the locking of the mounting frame 310.

[0118] The first locking module 510 includes:

[0119] The slide 511 is located on the side of the first storage platform 100 facing the second storage platform 200 and is slidably connected to the first storage platform 100; this sliding connection method can be achieved by setting a slide rail on the first storage platform 100, and setting a slider matching the slide rail at the bottom of the slide 511 to ensure that the slide 511 can slide smoothly on the first storage platform 100.

[0120] The locking pin 512 is connected to the slide 511. The locking pin 512 can slide with the slide 511 to be inserted into the lock hole 310K to lock the mounting frame 310 or withdraw from the lock hole 310K to unlock the mounting frame 310. The length and diameter of the locking pin 512 can be designed according to the size of the lock hole 310K of the mounting frame 310 to ensure that it can be smoothly inserted into the lock hole 310K to lock, or withdraw from the lock hole 310K to unlock. When the slide 511 slides, the locking pin 512 moves with the slide 511, thereby completing the locking and unlocking operations of the mounting frame 310.

[0121] The control component 513 is connected to the sliding seat 511 and is used to drive the sliding seat 511 to slide. The design of the control component 513 is intended to facilitate the operator to control the sliding of the sliding seat 511. The control component 513 may include a handle, which is connected to the sliding seat 511 through a linkage mechanism. The operator operates the handle to drive the linkage mechanism to move, thereby driving the sliding seat 511 to slide. This is only exemplary and not restrictive. In addition to being a manual structure, the control component 513 can also be set as an electric structure and adopt an electric unlocking method, which can be selected according to actual needs.

[0122] The first elastic member acts on the sliding seat 511 and is used to apply an elastic force to the sliding seat 511 to reset it. After the operator operates the control component 513 to make the sliding seat 511 slide and then releases the control component 513, the sliding seat 511 can automatically reset under the action of the first elastic member. Among them, the first elastic member can adopt a spring. In addition, the number of the first elastic members can be set to one or more, which is set according to actual needs.

[0123] Among them, on the moving path of the locking pin 512 of the first locking module 510, there are a locking position and an unlocking position. In the locked state, the locking pin 512 of the first locking module 510 is in the locking position and forms an insertion fit with the locking notch 310K on the mounting bracket 310, thereby restricting the disassembly of the mounting bracket 310.

[0124] When it is necessary to disassemble the lifting module 300 from the first storage table 100, the operator operates the control component 513 to drive the sliding seat 511 to slide so as to drive the locking pin 512 to withdraw from the locking notch 310K, that is, to move the locking pin 512 from the locking position to the unlocking position, thereby realizing the unlocking of the mounting bracket 310 and enabling the lifting module 300 to be disassembled from the first storage table 100. At the same time, the first elastic member is subjected to the action of the sliding seat 511 and stores elastic potential energy.

[0125] When it is necessary to fix the lifting module 300 to the first storage table 100, the operator can release the control component 513. The first elastic member releases elastic potential energy, drives the sliding seat 511 to slide so as to drive the locking pin 512 to insert into the locking notch 310K, that is, to move the locking pin 512 from the unlocking position to the locking position, thereby realizing the locking of the mounting bracket 310 and fixing the lifting module 300 to the first storage table 100. And under the elastic action of the first elastic member, the locking pin 512 remains in the locking position to stably insert into the locking notch 310K, thereby realizing the stable setting of the lifting module 300 on the first storage table 100.

[0126] The operator only needs to operate the control component 513 to easily slide the sliding seat 511, and then complete the locking and unlocking of the locking pin 512 on the mounting bracket 310. The entire operation process is simple and intuitive, without the need for additional tools, greatly saving operation time.

[0127] In some embodiments, referring to Figure 6 and Figure 7 , the locking pin 512 is located on the side of the first storage table 100 facing away from the second storage table 200;

[0128] The mounting bracket 310 is configured with a locking portion 311, and a locking opening 310K is formed in the locking portion 311;

[0129] The first storage table 100 is provided with a first opening 101, and the locking portion 311 passes through the first opening 101 and extends to the side of the first storage table 100 facing away from the second storage table 200, so that the locking opening 310K is arranged opposite to the locking pin 512.

[0130] Among them, the locking portion 311 is located at the bottom of the mounting bracket 310, and the shape and size of the locking portion 311 can be set according to the overall structure of the mounting bracket 310 and the connection requirements with the first storage table 100 to ensure its strength and stability. The size and shape of the first opening 101 on the first storage table 100 are adapted to the locking portion 311, which can not only ensure the smooth passing of the locking portion 311, but also provide a certain limiting effect on the mounting bracket 310 after locking, enhance the stability of the connection, and prevent the mounting bracket 310 from shaking and other situations.

[0131] The assembly process of the lifting module 300 can be as follows:

[0132] The operator operates the control component 513 to move the locking pin 512 from the locked position to the unlocked position, and then places the mounting bracket 310 at the mounting position of the first storage table 100, so that the locking portion 311 passes through the first opening 101 of the first storage table 100. On the side of the first storage table 100 facing away from the second storage table 200, the locking opening 310K on the locking portion 311 is aligned with the locking pin 512. Then, the operator releases the control component 513, and under the action of the first elastic member, the locking pin 512 moves from the unlocked position to the locked position to insert into the locking opening 310K, thereby locking the mounting bracket 310 and realizing the installation of the lifting module 300 on the first storage table 100.

[0133] And, the disassembly process of the lifting module 300 can be as follows:

[0134] The operator operates the control component 513 to move the locking pin 512 from the locked position to the unlocked position to withdraw from the locking port 310K, thereby unlocking the mounting bracket 310, and further the lifting module 300 can be detached. During the detachment of the lifting module 300, the locking portion 311 of the mounting bracket 310 is correspondingly withdrawn from the first opening 101.

[0135] In this embodiment, the locking cooperation between the locking pin 512 and the locking port 310K and the limiting effect of the locking portion 311 and the first opening 101 of the first placement table 100 enable the connection between the mounting bracket 310 and the first placement table 100 to effectively resist external forces such as vibration and bumps during vehicle movement.

[0136] In some embodiments, referring to Figure 3 、 Figure 5 and Figure 6 ,a vertical plate 110 is further provided at the installation position. The vertical plate 110 is disposed opposite to the sliding seat 511, and a receiving space for receiving the mounting bracket 310 is constructed between the sliding seat 511 and the vertical plate 110;

[0137] Wherein, the sliding seat 511 can slide towards the vertical plate 110 to cooperate with the vertical plate 110 to clamp the mounting bracket 310, or slide away from the vertical plate 110 to loosen the mounting bracket 310.

[0138] Specifically, when the mounting bracket 310 is placed at the installation position of the first placement table 100, the mounting bracket 310 is correspondingly located in the receiving space between the sliding seat 511 and the vertical plate 110. The sliding seat 511 can slide towards or away from the vertical plate 110. When the sliding seat 511 slides towards the vertical plate 110, the locking pin 512 is correspondingly driven to move towards the locking port 310K; when the sliding seat 511 slides away from the vertical plate 110, the locking pin 512 is correspondingly driven to move away from the locking port 310K. Correspondingly, when the sliding seat 511 drives the locking pin 512 to insert into the locking port 310K to lock the mounting bracket 310, the sliding seat 511 also cooperates with the vertical plate 110 to clamp the mounting bracket 310, so that the lifting module 300 is stably arranged on the first placement table 100. When the sliding seat 511 drives the locking pin 512 to withdraw from the locking port 310K to unlock the mounting bracket 310, the sliding seat 511 synchronously loosens the mounting bracket 310, so that the mounting bracket 310 can be disassembled and the lifting module 300 can be folded.

[0139] The setting of the vertical plate 110 further enhances the fixing effect on the mounting bracket 310. When the sliding seat 511 clamps the mounting bracket 310 with the vertical plate 110 and is combined with the locking of the locking pin 512 and the locking opening 310K, it can effectively resist the vibration and external force during vehicle driving, ensuring the stable connection between the mounting bracket 310 and the first storage table 100. The material of the vertical plate 110 can be selected as high-strength metal, such as stainless steel or aluminum alloy, to ensure its strength and durability. Moreover, the vertical plate 110 can be a plate body separately provided on the first storage table 100, or the first storage table 100 itself can be a frame structure with a border plate arranged at the edge position, and the vertical plate 110 is the border plate of the first storage table 100, which is set according to actual needs.

[0140] In some embodiments, referring to Figure 3 and Figure 5 , the sliding seat 511 is provided with a receiving groove, and the control assembly 513 includes:

[0141] A mounting seat 5131, which is arranged on the first storage table 100;

[0142] A rotating push frame 5132, which is rotatably connected to the mounting seat 5131. The rotating push frame 5132 is configured with a push rod 5132G, and the push rod 5132G is received in the receiving groove so that the sliding seat 511 and the rotating push frame 5132 form a linkage cooperation. The rotating push frame 5132 is used to rotate when subjected to an external force to push the sliding seat 511 to slide through its push rod 5132G.

[0143] The operator can operate the rotating push frame 5132 to rotate on the mounting seat 5131 so that the push rod 5132G pushes the sliding seat 511 to slide. The design of the rotating push frame 5132 of the control assembly 513 utilizes the lever principle, enabling the operator to apply a relatively small external force when operating, easily realizing the sliding of the sliding seat 511, and further completing the unlocking and locking operations of the mounting bracket 310, making the operation more labor-saving and convenient. In actual application scenarios, the operator can operate the rotating push frame 5132 by means such as stepping on it with the foot or pressing it with the hand, which is convenient to use.

[0144] In some embodiments, referring to Figure 1 , Figure 2 and Figure 8 , the second storage table 200 is connected with a rotating seat 600, and the lifting drive assembly 320 is connected with the rotating seat 600 and can drive the rotating seat 600 to drive the second storage table 200 to rise or fall;

[0145] The mounting bracket 310 is slidably connected with the rotating seat 600 and can rotate relative to the second storage table 200 through the rotating seat 600 to perform horizontal folding or vertical unfolding.

[0146] Among them, the rotating seat 600 can be in a semi-frame shape and sleeved on the mounting frame 310, forming a driving connection relationship with the lifting drive assembly 320 and a sliding connection relationship with the mounting frame 310. The design of the rotating seat 600 provides the basic support and movement mode for the lifting of the second storage table 200 and the rotation of the mounting frame 310. As the power source, when the lifting drive assembly 320 is started, it transmits power to the rotating seat 600 connected thereto. For example, if the lifting drive assembly 320 adopts a lead screw nut structure, the motor drives the lead screw to rotate, and the nut seat connected to the rotating seat 600 will move along the lead screw direction as the lead screw rotates. If a hydraulic drive structure is adopted, the hydraulic pump delivers high-pressure hydraulic fluid to the hydraulic cylinder to push the piston to drive the rotating seat 600 to move.

[0147] Driven by the lifting drive assembly 320, the rotating seat 600 generates a vertical displacement. Since the second storage table 200 is connected to the rotating seat 600, the vertical movement of the rotating seat 600 will drive the second storage table 200 to rise or fall synchronously. This connection method ensures that the second storage table 200 can be smoothly adjusted in height to meet the height requirements of the storage table in different shooting scenarios.

[0148] Among them, the mounting frame 310 and the rotating seat 600 can be connected through a specific sliding structure, such as the cooperation of a guide rail and a slider. When the mounting frame 310 needs to be folded or unfolded, the mounting frame 310 can slide on the rotating seat 600 along the sliding structure to adjust its own position, so as to prepare for subsequent rotation.

[0149] The mounting frame 310 and the rotating seat 600 not only have a sliding connection, but also have a rotating connection characteristic. After the mounting frame 310 slides to a suitable position, it can rotate relative to the second storage table 200 by means of the rotating seat 600. When the vehicle is working, the mounting frame 310 is in a vertically unfolded state and works together with the lifting drive assembly 320, the first storage table 100, and the second storage table 200 to support and drive the lifting of the second storage table 200. When the vehicle needs to be stored, the mounting frame 310 rotates relative to the second storage table 200 to a horizontally folded state through the rotating seat 600, thereby reducing the space occupied by the vehicle.

[0150] In some embodiments, referring to Figures 8 to 10 , a second locking module 520 is provided between the rotating seat 600 and the second storage table 200. A fixing frame 210 is provided on one side of the second storage table 200 facing the first storage table 100, and a hook groove 210C is provided on the fixing frame 210;

[0151] The second locking module 520 includes:

[0152] The locking hook 521 is rotatably connected to the rotating seat 600. The locking hook 521 is used to form a hooking fit with the hook groove 210C to lock the rotating seat 600 or cancel the hooking fit with the hook groove 210C to unlock the rotating seat 600;

[0153] The unlocking pressing member 522 is movably disposed through the second storage table 200 and is disposed opposite to the hook groove 210C. The unlocking pressing member 522 is used to move when subjected to an external force to push the hook member out of the hook groove 210C;

[0154] The second elastic member acts on the unlocking pressing member 522. The second elastic member is used to apply an elastic acting force to the unlocking pressing member 522 to reset it.

[0155] Specifically, the locking hook 521 is rotatably connected to the rotating seat 600. When the rotating seat 600 needs to drive the second storage table 200 to rise or fall, a hooking fit is formed between the locking hook 521 and the hook groove 210C on the fixing frame 210. Due to the mutually adapted shape designs of the locking hook 521 and the hook groove 210C, this hooking fit can prevent the rotating seat 600 from rotating, thereby realizing the locking of the rotating seat 600 and ensuring the stability of the second storage table 200 during operation. Moreover, in the normal locked state, the second elastic member is in a natural stretched state, and it applies an elastic acting force to the unlocking pressing member 522 to keep it in the initial position, ensuring that the unlocking pressing member 522 will not be accidentally triggered, thereby maintaining the stable hooking between the locking hook 521 and the hook groove 210C.

[0156] When it is necessary to unlock the rotating seat 600 for operations such as storage, the operator applies an external force to the unlocking pressing member 522. Since the unlocking pressing member 522 is movably disposed through the second storage table 200 and is disposed opposite to the hook groove 210C, the external force pushes the unlocking pressing member 522 to move in the direction close to the hook groove 210C. As the unlocking pressing member 522 moves, it contacts the locking hook 521 and pushes the locking hook 521 out of the hook groove 210C. At this time, the hooking fit between the locking hook 521 and the hook groove 210C is cancelled, and the locked state of the rotating seat 600 is released. Subsequently, the operator can perform the folding operation of the mounting bracket 310 to realize vehicle storage. When the operator releases the external force on the unlocking pressing member 522 (such as releasing the unlocking pressing member 522), the second elastic member begins to play a role. Since the external force compressed the second elastic member before, at this time it releases elastic potential energy and applies an elastic acting force to the unlocking pressing member 522 to reset it, pushing the unlocking pressing member 522 back to the initial position to prepare for the next unlocking operation. Among them, the unlocking pressing member 522 can be an unlocking button. The second storage table 200 is configured with a through hole, and the unlocking button is disposed through the through hole. One end of the unlocking button is a pressing end, and the other end is a pushing end for acting on the locking hook 521. The second elastic member can be a spring, and the spring is disposed in the through hole and sleeved on the unlocking button.

[0157] The locking hook 521 of the second locking module 520 engages with the hook groove 210C, providing additional stability for the second storage platform 200 in the working state. Even when the vehicle encounters bumpy roads or other vibrations during driving, it can effectively prevent the rotating seat 600 from accidentally rotating, ensuring that the photographic equipment placed on the second storage platform 200 always remains stable and avoiding affecting the shooting quality due to shaking or displacement.

[0158] By providing a movable unlocking pressing member 522, the operator can easily unlock the rotating seat 600 by simply applying an external force thereto. This operation method does not require additional tools, and the operation process is intuitive and easy to understand, greatly improving the operation efficiency. Moreover, the second elastic member can automatically reset the unlocking pressing member 522 after the unlocking operation is completed, eliminating the need for the operator to manually reset it, reducing the operation steps and further enhancing the operation convenience.

[0159] The second locking module 520 has good compatibility with the original lifting drive assembly 320, mounting bracket 310, etc. of the photographic auxiliary mobile vehicle, and can effectively improve the overall performance of the vehicle without affecting the functions of the original structures.

[0160] In some embodiments, referring to Figure 8 , the rotating seat 600 is sleeved on the mounting bracket 310, and the mounting bracket 310 is provided with a guide rail assembly. The rotating seat 600 is connected to the slider of the guide rail assembly to be slidably connected to the mounting bracket 310.

[0161] Specifically, two guide rail assemblies can be provided. The two guide rail assemblies are respectively arranged on opposite sides of the mounting bracket 310, and the rotating seat 600 is connected to the sliders of both guide rail assemblies. The guide rail assembly generally consists of a guide rail and a slider that cooperates with it. The shape and size of the guide rail are designed according to the structure of the mounting bracket 310 and the movement requirements of the rotating seat 600, and are generally linear guide rails with a smooth surface and high precision, which can provide a stable sliding track for the slider.

[0162] The rotating seat 600 is sleeved on the mounting bracket 310 and connected to the slider of the guide rail assembly. This connection method enables the rotating seat 600 to slide on the guide rail by means of the slider. When an external force acts on the rotating seat 600, the rotating seat 600 drives the slider to move on the guide rail, realizing the sliding of the rotating seat 600 relative to the mounting bracket 310. For example, when adjusting the position of the second storage platform 200, the lifting drive assembly 320 or other external forces act on the rotating seat 600, and the rotating seat 600 slides smoothly on the guide rail through the slider.

[0163] In some embodiments, referring to Figure 8 and Figure 9The second storage table 200 is provided with a second opening 201, the fixing frame 210 is located at one side of the second opening 201, and the mounting frame 310 is passed through the second opening 201; this design establishes a basic positional relationship between the mounting frame 310 and the second storage table 200, and the mounting frame 310 can be arranged at a specific position of the second storage table 200 through the second opening 201, and at the same time provides a spatial basis for the installation and movement of the rotating seat 600 and related components.

[0164] The rotating seat 600 is located in the second opening 201 and is rotatably connected to the edge of the second opening 201. The rotating seat 600 at least partially extends to the side of the second storage platform 200 facing the first storage platform 100 and is provided with a locking hook 521. This rotatable connection mode enables the rotating seat 600 to rotate around the edge of the second opening 201, providing a movement basis for subsequent folding, unfolding, and locking actions. The position and structural design of the locking hook 521 are adapted to the hook groove 210C on the fixing frame 210, preparing for the realization of the locking function.

[0165] Specifically, the cooperation between the second opening 201 of the second storage table 200 and the mounting bracket 310, and the rotational connection between the rotating seat 600 and the edge of the second opening 201, provide accurate positioning and a stable support basis for the entire structure. The mounting bracket 310 is inserted through the second opening 201, and its position on the second storage table 200 can be accurately determined to reduce shaking and deviation during operation. The connection method between the rotating seat 600 and the edge of the second opening 201 ensures rotation flexibility while also enhancing the stability of the structure.

[0166] In some embodiments, reference Figure 10 and Figure 11 A third locking module 530 is provided between the lifting drive assembly 320 and the rotating seat 600, and the rotating seat 600 is provided with a locking groove 600C. The third locking module 530 includes:

[0167] The locking tongue 531 is connected to the lifting drive assembly 320 and can move under the drive of the lifting drive assembly 320;

[0168] The abutment member 532 is movably disposed on the rotating base 600, and the abutment member 532 is used to press the locking tongue 531 to lock the locking tongue 531 into the locking groove 600C or to loosen the locking tongue 531 so that the locking tongue 531 can be removed from the locking groove 600C;

[0169] a third elastic member, acting on the resisting member 532, and the third elastic member is used to apply an elastic force to the resisting member 532 to reset it;

[0170] The lifting drive assembly 320 is detachably connected to the rotating seat 600 through the engagement between the locking tongue 531 and the locking groove 600C, and can transmit driving power to the rotating seat 600 .

[0171] When the lifting drive assembly 320 is started and in working state, it drives the locking tongue 531 to move. The rotating seat 600 is provided with a locking groove 600C. When it is necessary to lock the connection between the rotating seat 600 and the lifting drive assembly 320, the lifting drive assembly 320 pushes the locking tongue 531 to move toward the rotating seat 600 (such as descending) until the locking tongue 531 is inserted into the locking groove 600C to form a snap fit. This snap fit allows the lifting drive assembly 320 to be tightly connected to the rotating seat 600. The lifting drive assembly 320 can transmit driving power to the rotating seat 600 through the connection between the locking tongue 531 and the locking groove 600C, driving the rotating seat 600 and the second storage platform 200 connected thereto to perform lifting and other operations.

[0172] The abutting member 532 is movably disposed on the rotating seat 600, and its function is to abut the locking tongue 531 after the locking tongue 531 is inserted into the locking groove 600C. When the locking tongue 531 is inserted into the locking groove 600C, the abutting member 532 automatically moves to contact with the locking tongue 531 and applies pressure under the action of the third elastic member, and abuts the locking tongue 531 tightly in the locking groove 600C to prevent the locking tongue 531 from accidentally coming out, thereby ensuring the stable connection between the rotating seat 600 and the lifting drive assembly 320 and ensuring the reliability of power transmission. The third elastic member can be a spring.

[0173] When the locking connection between the rotating seat 600 and the lifting drive assembly 320 needs to be released, such as when the vehicle is stored or some special adjustments are made, the operator applies external force to the abutting member 532. Since the abutting member 532 is movably arranged, the external force overcomes the elastic force of the third elastic member, causing the abutting member 532 to move, thereby loosening the abutment on the locking tongue 531.

[0174] After the abutment 532 loosens the locking tongue 531, the lifting drive assembly 320 drives the locking tongue 531 to move in the opposite direction (e.g., upward) and escape from the locking groove 600C. At this time, the locking connection between the rotating seat 600 and the lifting drive assembly 320 is released, and the rotating seat 600 can move independently under the action of other external forces (e.g., manually pushed for folding operations, etc.), and is no longer restricted by the direct driving connection of the lifting drive assembly 320. When the operator releases the external force on the abutment 532, the third elastic member takes effect and pushes the abutment 532 back to the initial position, preparing for the next locking operation.

[0175] During the normal lifting and lowering operation, the third locking module 530 ensures the stable connection between the lifting drive assembly 320 and the rotating seat 600. The lifting drive assembly 320 transmits power to the rotating seat 600 through the engagement of the locking tongue 531 with the locking groove 600C, and the rotating seat 600 drives the second storage table 200 to rise or fall. At the same time, the rotational connection between the rotating seat 600 and the edge of the second opening 201 and the connection with the slider of the guide rail assembly ensure the smoothness and stability of the movement of the rotating seat 600 during the lifting process. Each structure works together to achieve the smooth lifting and lowering operation of the second storage table 200. When folding or unfolding the mounting frame 310, first apply an external force to the abutting member 532 to release the locking of the third locking module 530, so that the rotating seat 600 is separated from the lifting drive assembly 320. Then, the operator can push the rotating seat 600 to rotate it around the edge of the second opening 201, and at the same time slide the slider on the guide rail to complete the folding or unfolding operation of the mounting frame 310. After completing the folding or unfolding, if it is necessary to reconnect the lifting drive assembly 320 for subsequent work, start the lifting drive assembly 320 again, so that the locking tongue 531 is inserted into the locking groove 600C, and the abutting member 532 automatically abuts against the locking tongue 531 to restore the connection between the rotating seat 600 and the lifting drive assembly 320, preparing for the next lifting operation.

[0176] Through the engagement cooperation of the locking tongue 531 with the locking groove 600C and the abutting action of the abutting member 532, the third locking module 530 provides a reliable connection method between the lifting drive assembly 320 and the rotating seat 600. During the vehicle operation, it can effectively ensure that the power of the lifting drive assembly 320 is stably transmitted to the rotating seat 600, driving the second storage table 200 to perform the lifting and lowering operation. Moreover, under the action of the third elastic member, the abutting member 532 automatically abuts against the locking tongue 531 to prevent the locking tongue 531 from accidentally disengaging. The operator only needs to apply an external force to the abutting member 532 to easily release the locking connection between the rotating seat 600 and the lifting drive assembly 320, and the operation process is simple and intuitive. By setting the connection between the rotating seat 600 and the lifting drive assembly 320 to be releasable, it can avoid interference with the lifting module 300 when it is lifted and separated from the first storage table 100, thus facilitating the folding and storage of the lifting module 300.

[0177] In some embodiments, referring to Figure 10 and Figure 11 , the locking groove 600C is provided with a notch for the locking tongue 531 to enter or exit the locking groove 600C along its moving direction;

[0178] The abutting member 532 is used to block the notch by moving to make the locking tongue 531 engage with the locking groove 600C or open the notch to enable the locking tongue 531 to disengage from the locking groove 600C.

[0179] During the locking process, when the locking tongue 531 completely enters the locking groove 600C, under the action of the third elastic member, the abutting member 532 automatically moves to the notch position to block the notch. Due to the blocking of the abutting member 532, the locking tongue 531 is restricted within the locking groove 600C and cannot easily escape from the notch, ensuring the stability of the connection between the rotating seat 600 and the lifting drive assembly 320 and guaranteeing the reliability of power transmission.

[0180] During the unlocking process, the operator applies an external force to the abutting member 532. The external force overcomes the elastic force of the third elastic member, causing the abutting member 532 to move away from the notch position, thereby opening the notch. After the notch is opened, the lifting drive assembly 320 drives the locking tongue 531 to move in the reverse direction. The locking tongue 531 follows the path of entering the locking groove 600C and exits the locking groove 600C through the opened notch. At this time, the locking connection between the rotating seat 600 and the lifting drive assembly 320 is released, and the rotating seat 600 is no longer directly driven and connected by the lifting drive assembly 320 and can move independently under the action of other external forces (such as manual pushing for folding operations, etc.). When the operator removes the external force on the abutting member 532 (such as releasing the abutting member 532), the third elastic member comes into play and pushes the abutting member 532 back to the notch position to prepare for the next locking operation.

[0181] In some embodiments, referring to Figure 10 and Figure 11 , one end of the abutting member 532 is configured with an abutting portion 5321 that can enter or exit the locking groove 600C, and the other end of the abutting member 532 is configured with a control portion 5322. The abutting portion 5321 is used to block or open the notch, and the control portion 5322 is used to drive the abutting portion 5321 to move when subjected to an external force.

[0182] Specifically, by operating the control portion 5322, the operator can cause the abutting member 532 to slide horizontally to allow the abutting portion 5321 to enter the locking groove 600C to block the notch or exit the locking groove 600C to open the notch. Among them, the control portion 5322 can be in the shape of a pull ring for the convenience of the operator's operation.

[0183] When it is necessary to lock and connect the rotating seat 600 and the lifting drive assembly 320, for example, when the vehicle is unfolded for use, the lifting drive assembly 320 drives the locking tongue 531 to enter the locking groove 600C and cross over the abutting member 532. Subsequently, the abutting member 532 moves under the action of the third elastic member, causing the abutting portion 5321 to enter the locking groove 600C and block the notch. Due to the blocking of the abutting portion 5321, the locking tongue 531 is restricted within the locking groove 600C.

[0184] When it is necessary to release the locking connection between the rotating base 600 and the lifting drive assembly 320, for example, when the vehicle is being stowed or undergoing special adjustments, an operator applies an external force to the control portion 5322 of the abutting member 532. Since the control portion 5322 is connected to the abutting portion 5321, the external force is transmitted through the control portion 5322, driving the abutting portion 5321 to move. Under the action of the external force transmitted by the control portion 5322, the abutting portion 5321 moves away from the notch position, thus opening the notch.

[0185] In some embodiments, referring to Figure 12 , the lifting chain module 400 includes:

[0186] A box body 410, connected to the first storage table 100; wherein, the box body 410 provides protection and an installation basis for the internal components of the lifting chain module 400.

[0187] A lifting chain 420, disposed in the box body 410 in a liftable manner and connected to the second storage table 200; wherein, the lifting chain is the direct execution component for realizing the lifting of the second storage table 200.

[0188] A gear set 430, disposed in the box body 410 and in transmission connection with the lifting chain 420, the gear set 430 is used to receive driving power to drive the lifting chain 420, so that the lifting chain 420 drives the second storage table 200 to rise or fall. Among them, the function of the gear set 430 is to receive driving power (such as the driving power output by the driving module in the foregoing embodiments), and through its own gear transmission structure, convert the power into the driving force for the lifting chain 420 to rise or fall, so that the lifting chain 420 drives the second storage table 200 to rise or fall.

[0189] After the gear set 430 of the lifting chain module 400 receives the driving power, the driving gear in the gear set 430 starts to rotate under the action of the driving power. The driving gear transmits the rotational motion to a specific gear (such as the transmission gear in subsequent embodiments) connected to the lifting chain 420 through precise meshing with the driven gear. As the specific gear continues to rotate, the lifting chain 420 rises or falls in the box body 410 along a predetermined track, directly driving the second storage table 200 to move up or down relative to the first storage table 100. In this process, the precise transmission of the gear set 430 ensures the smoothness and accuracy of the movement of the lifting chain 420, and finally realizes the flexible and stable adjustment of the height of the storage table.

[0190] Optionally, as Figure 12 shown, a main channel 411 and two recovery channels 412 are constructed in the box body 410. The main channel 411 extends along the height direction of the box body 410. One end of the main channel 411 is provided with a channel outlet. The two recovery channels 412 are separately disposed on opposite sides of the main channel 411 and communicate with the other end of the main channel 411;

[0191] The lifting chain 420 includes two oppositely arranged chain bodies 421. One of the two chain bodies 421 is accommodated in one of the two recovery channels 412 and the main channel 411, and extends out from the channel outlet; the other of the two chain bodies 421 is accommodated in the other of the two recovery channels 412 and the main channel 411, and extends out from the channel outlet; the extending ends of the two chain bodies 421 are connected with a connecting seat 440, and are connected with the second placement table 200 through the connecting seat 440;

[0192] The gear set 430 includes two transmission gears 431. The two transmission gears 431 are respectively meshed with the two chain bodies 421, and are used for meshing and driving the chain bodies 421 to rise or fall by rotation; during the rising process of the two chain bodies 421, they move from the recovery channel 412 towards the main channel 411 to close towards each other, and during the falling process, they move from the main channel 411 towards the recovery channel 412 to separate away from each other.

[0193] When the height of the second placement table 200 needs to be adjusted, the gear set 430 of the lifting chain module 400 receives driving power. The two transmission gears 431 in the gear set 430 rotate in opposite directions under the action of the driving power. The two chain bodies 421 meshed with the transmission gears 431 start to move under the meshing drive of the transmission gears 431.

[0194] Specifically, during the rising process, with the rotation of the transmission gear 431, the chain body 421 receives an upward acting force, moves gradually from the recovery channel 412 towards the main channel 411, the two chain bodies 421 close towards each other, and can achieve mutual engagement. Since the two chain bodies 421 are connected with the second placement table 200 through the connecting seat 440, the rising of the chain body 421 drives the second placement table 200 to rise synchronously.

[0195] During the falling process, the driving module runs in reverse, the transmission gear 431 rotates in the reverse direction, the chain body 421 receives a downward acting force, moves from the main channel 411 towards the recovery channel 412, the two chain bodies 421 separate away from each other, and further drive the second placement table 200 to fall.

[0196] The setting of the recovery channel 412 in the box body 410 enables the chain body 421 to enter the recovery channel 412 from the main channel 411 orderly to achieve recovery when the lifting chain 420 is stored. The entire structure of the lifting chain module 400 is compact and does not occupy too much space.

[0197] The recovery channel 412 includes a first sub-recovery channel 4121 and a second sub-recovery channel 4122. The second sub-recovery channel 4122 is arranged in parallel with the first sub-recovery channel 4121 along the height direction of the box body 410. One end of the first sub-recovery channel 4121 is communicated with the main channel 411, and the second sub-recovery channel 4122 is communicated with the other end of the first sub-recovery channel 4121.

[0198] Among them, in the height direction of the box body 410, the first sub-recovery channel 4121 may be located below the second sub-recovery channel 4122, and the second sub-recovery channel 4122 may be located above the first sub-recovery channel 4121; or, the second sub-recovery channel 4122 may be located below the first sub-recovery channel 4121, and the first sub-recovery channel 4121 may be located above the second sub-recovery channel 4122.

[0199] During the ascending process of the lifting chain 420, as the chain body 421 continuously extends outward from the channel outlet of the main channel 411, the chain body 421 inside the box body 410 moves from the second sub-recovery channel 4122 towards the first sub-recovery channel 4121; while during the descending process of the lifting chain 420, as the chain body 421 continuously retracts inward from the channel outlet of the main channel 411, the chain body 421 inside the box body 410 moves from the first sub-recovery channel 4121 towards the second sub-recovery channel 4122.

[0200] The double sub-recovery channel design of the first sub-recovery channel 4121 and the second sub-recovery channel 4122 adopted by the recovery channel 412 enables the chain body 421 to be folded and accommodated in the height direction of the box body 410 during the recovery process, thereby avoiding occupying a large space in the length direction of the placing table and contributing to improving the structural compactness.

[0201] In some embodiments, referring to Figure 1 , the number of the lifting chain modules 400 is set to at least two, and the lifting module 300 and at least two lifting chain modules 400 are distributed on the peripheral side position of the first placing table 100.

[0202] Among them, the number of the lifting chain modules 400 can be two or more than two, which is set according to actual needs. The multiple lifting chain modules 400 work together, which can significantly improve the bearing capacity of the photographic auxiliary mobile vehicle for the second placing table 200 and the photographic equipment carried thereon. Each lifting chain module 400 can bear a part of the weight, so that the overall structure can bear a heavier load.

[0203] When the number of the lifting chain modules 400 is set to at least two and they are distributed around the circumference of the first placing table 100 together with the lifting module 300, more uniform supporting force can be provided for the second placing table 200. During the process of the second placing table 200 carrying photographic equipment and performing lifting operations, multiple lifting chain modules 400 work together to evenly disperse the weight around the circumference of the first placing table 100. For example, when heavier photographic equipment is placed on the second placing table 200, two or more lifting chain modules 400 can apply supporting forces to the second placing table 200 from different directions respectively, avoiding single-point stress or uneven local stress, and greatly reducing the possibility of the second placing table 200 shaking or tilting due to uneven stress. Moreover, by distributing the lifting chain modules 400 and the lifting module 300 around the circumference of the first placing table 100, the space of the vehicle can be utilized more reasonably. Compared with concentrating all the modules in one place, the circumferential distribution can avoid mutual interference between the modules and leave more space inside the first placing table 100 and other positions for placing other equipment such as photographic props and batteries. For example, a lifting chain module 400 is installed on one side of the first placing table 100, and a lifting module 300 is installed on the other side, and the middle area can be used to store items such as photographic tripods and lenses, improving the utilization rate of the vehicle space and enabling the photographic auxiliary mobile vehicle to carry more equipment within a limited space to meet the requirements of different shooting tasks.

[0204] In some embodiments, referring to Figure 1 and Figure 13 , the photographic auxiliary mobile vehicle further includes:

[0205] Multiple wheel assemblies 700, which are arranged on the first placing table 100, and the wheel assemblies 700 drive the first placing table 100 to move by moving on the walking surface.

[0206] Specifically, the wheel assemblies 700 are connected to the first placing table 100, and their power sources are usually motors or human power. When driven by a motor, the motor converts electrical energy into mechanical energy and transmits the power to the wheel shafts in the wheel assemblies 700 through a transmission device (such as gears, etc.) to drive the wheels to rotate. In the case of human power drive, the operator drives the photographic auxiliary mobile vehicle to make the wheels roll on the walking surface.

[0207] The wheel assembly 700 is disposed on the first storage platform 100. The first storage platform 100 carries equipment such as the lifting module 300, the lifting chain module 400, the second storage platform 200, and photographic equipment. The rotation of the wheel assembly 700 drives the first storage platform 100 to move, thereby realizing the movement of the entire photographic auxiliary mobile vehicle. During the movement, the wheel assembly 700 needs to bear the entire weight of the vehicle, including the weight of the first storage platform 100 itself and the weight of all the equipment and instruments placed thereon. At the same time, the smooth operation of the wheel assembly 700 also provides a guarantee for the normal operation of other components.

[0208] The photographic auxiliary mobile vehicle needs to have different moving capabilities in different shooting scenarios. The design of the wheel assembly 700 needs to cooperate with other components to adapt to various working scenarios. For example, in an indoor shooting scenario, the vehicle may need to have flexible steering capabilities and a small turning radius. The wheel assembly 700 can be achieved through special steering mechanisms (such as omnidirectional wheels or multi-axis steering systems). In an outdoor shooting scenario, the vehicle may need to have better passability. The wheel assembly 700 can adopt larger-sized wheels, a higher ground clearance, and tires with good grip to cope with rough roads.

[0209] In some embodiments, referring to Figure 13 , the wheel assembly 700 includes:

[0210] A wheel frame 710, rotatably connected to the first storage platform 100;

[0211] Wheels 720, rotatably disposed on the wheel frame 710. The wheels 720 can rotate with the wheel frame 710 relative to the first storage platform 100 to perform horizontal folding or vertical unfolding;

[0212] A fourth locking module 730, disposed on the first storage platform 100. The fourth locking module 730 is used to lock the wheel frame 710 to limit the rotation of the wheel frame 710 relative to the first storage platform 100 or unlock the wheel frame 710 to enable the wheel frame 710 to rotate relative to the first storage platform 100.

[0213] The wheel frame 710 is connected to the first storage platform 100 through a special rotational connection structure, such as a hinge or a rotatable pin connection. This connection method gives the wheel frame 710 the freedom to rotate around a specific axis relative to the first storage platform 100, just like a door rotates around a hinge. For example, when using a pin connection, the pin penetrates the corresponding installation parts of the wheel frame 710 and the first storage platform 100, and the wheel frame 710 can rotate around the pin within a range of about 0° to 90°, providing a physical basis for realizing the horizontal folding or vertical unfolding of the wheels 720.

[0214] The wheel 720 is rotatably disposed on the wheel frame 710. When the wheel frame 710 rotates relative to the first storage platform 100, the wheel 720 moves with the wheel frame 710. In the vertical unfolded state, the wheel 720 is in contact with the ground, and provides mobility for the photography auxiliary mobile vehicle through rotation. In the horizontal folded state, the wheel 720 is off the ground, reducing the floor space occupied by the vehicle during storage or transportation, and facilitating the storage and transportation of the vehicle.

[0215] The fourth locking module 730 may be composed of a lock buckle, a lock column, a spring and other components, and is installed at a position of the first storage platform 100 near the rotation connection point of the wheel frame 710. When it is necessary to limit the rotation of the wheel frame 710, the lock column is ejected and inserted into a preset slot or lock hole on the wheel frame 710 through manual operation or a specific control mechanism, and the wheel frame 710 is limited to rotate relative to the first storage platform 100 by mechanical locking, so as to ensure that the wheel 720 stably supports the vehicle in the vertical unfolded state, and prevent the wheel frame 710 from accidentally rotating during driving and causing the vehicle to lose control. When it is necessary to change the state of the wheel frame 710, the fourth locking module 730 is operated again to overcome the spring resistance to retract the lock column, release the lock on the wheel frame 710, and allow the wheel frame 710 to rotate freely, thereby realizing the folding or unfolding action of the wheel 720.

[0216] When the vehicle is working normally, the wheel 720 is in a vertically unfolded state, the fourth locking module 730 locks the wheel frame 710, and the wheel 720 contacts the ground and rolls on the walking surface, driving the first storage platform 100 and the entire vehicle to move. The wheel assembly 700 works in conjunction with other components of the first storage platform 100, such as the lifting module 300, the lifting chain module 400, etc., to provide support for the movement and shooting operations of the photography auxiliary mobile vehicle. For example, during the driving of the vehicle, the stable rotation of the wheel 720 provides a guarantee for the smooth operation of the lifting module 300 and the lifting chain module 400, ensuring that the photographic equipment on the second storage platform 200 will not be affected by the movement of the vehicle.

[0217] When the photography-assisted mobile vehicle needs to be stored or transported, the operator unlocks the wheel frame 710 through the fourth locking module 730, rotates the wheel frame 710 to a horizontal folded state, and then locks the wheel frame 710 in the folded position again through the fourth locking module 730. At this time, the wheels 720 are off the ground, and the overall height and footprint of the vehicle are reduced, which is convenient for storage or transportation in an environment with limited space. For example, when the photography-assisted mobile vehicle is placed in a small warehouse or a compartment of a transport vehicle, the folded wheel assembly 700 can make the vehicle more easily adapt to space limitations.

[0218] In some embodiments, reference Figure 6 , the photography auxiliary mobile vehicle also includes:

[0219] The driving module 800 is disposed on the first storage table 100 and is respectively drivingly connected to the lifting module 300 and the lifting chain module 400. The driving module 800 is used to drive the lifting module 300 and the lifting chain module 400 to operate;

[0220] The battery module 900 is disposed on the first storage table 100 and is electrically connected to the driving module 800. The battery module 900 is used to supply power to the driving module 800.

[0221] In this embodiment, the driving module 800 is installed on the first storage table 100 and is drivingly connected to the lifting module 300 and the lifting chain module 400. As a power output source, the driving module 800 is used to drive the lifting module 300 and the lifting chain module 400 to operate, providing power support for the lifting of the second storage table 200. The driving module 800 may include a driving motor and a transmission device. The output shaft of the driving motor is connected to the transmission device, and the transmission device is connected to the lifting module 300 and the lifting chain module 400. The transmission device may adopt components such as gears, belts, and rotating rods. When the driving motor operates, power is transmitted to the lifting module 300 and the lifting chain module 400 through the transmission device, so that the lifting module 300 and the lifting chain module 400 operate synchronously.

[0222] As an independent power supply unit, the battery module 900 provides stable power for the driving module. This design gets rid of the dependence on external power sources, enabling the photography assistant mobile vehicle to be flexibly used in various shooting environments. Whether it is an indoor photography studio with limited power interfaces or an outdoor shooting site without power supply, it can ensure the normal use of the vehicle's storage table lifting function.

[0223] In some embodiments, the battery module 900 is detachably connected to the first storage table 100. Specifically, the battery module 900 is physically connected to the bottom or side of the first storage table 100 through mechanical interfaces (such as buckles, guide rails, quick-release bolts, etc.) and is electrically connected to the driving module 800 through electrical interfaces. This design supports the quick disassembly of the battery module 900 while maintaining structural stability and electrical reliability. As an example, the first storage table 100 is provided with guide rails, and the bottom of the battery module 900 matches the guide rail chute. After insertion, it is locked by a spring buckle, supporting one-handed operation for unlocking. When the battery module 900 runs out of power, it can be directly replaced without stopping for charging, which helps to save time and improve efficiency.

[0224] The present invention also provides a storage method for a photography-assist mobile vehicle. The photography-assist mobile vehicle involved can be the one described above, and its specific structure refers to the foregoing embodiments. It is equipped with a lifting module 300 and a lifting chain module 400, which together serve as the power source for driving the lifting of the second storage platform 200. The common type of the lifting module 300 is a motor-driven lead screw and nut structure. When the motor operates, its output shaft drives the lead screw to rotate, and the nut seat rigidly connected to the second storage platform 200 will move along the axial direction of the lead screw due to the rotation of the lead screw, thereby realizing the lifting of the second storage platform 200. The lifting chain module 400 drives the chain through a motor, and the chain is reliably connected to the second storage platform 200. When the motor operates, the chain elongates or shortens under the drive of the sprocket, thereby assisting the lifting module 300 to ensure the stable lifting of the second storage platform 200. When the vehicle needs to be stored, a reverse instruction is sent to the motors of the lifting module 300 and the lifting chain module 400 through the control system. The reverse rotation of the motors generates a downward driving force, driving the second storage platform 200 to descend relative to the first storage platform 100.

[0225] A detachable connection structure is adopted between the lifting module 300 and the first storage platform 100. Common ones include bolt connection, snap connection or plug-and-play connection. During the normal operation of the vehicle, these connection structures can firmly connect the lifting module 300 and the first storage platform 100 by virtue of their own mechanical locking functions, ensuring that the entire structure has sufficient stability during the process of the lifting module 300 driving the second storage platform 200 to lift, and will not loosen or displace due to external forces. During storage, the operator can use simple tools, such as wrenches, screwdrivers, etc., or through manual operation, to release the locked state of these connection structures and realize the disassembly and separation of the lifting module 300 and the first storage platform 100. Disassembling and separating the lifting module 300 from the first storage platform 100 is mainly to be able to more flexibly adjust the positions of the vehicle components during storage, effectively reducing the overall occupied space. The separated lifting module 300 can be folded separately later, forming a relatively independent storage unit with the first storage platform 100 and the second storage platform 200, which is convenient for storage in a narrow space and greatly improves the space utilization efficiency.

[0226] The lifting module 300 is connected to the second storage platform 200 through a specific rotational connection structure, such as a hinge or a rotatable pin connection. This rotational connection method gives the lifting module 300 the freedom to rotate relative to the second storage platform 200 around a specific axis. After the lifting module 300 is disassembled and separated from the first storage platform 100, the operator manually applies force to push the lifting module 300 to rotate around the connection point, gradually changing it from the vertical working state to the horizontal folded state.

[0227] By horizontally folding the lifting module 300, the overall height of the vehicle will be significantly reduced, and the floor area will also be correspondingly decreased. For example, when storing the vehicle in the corner of a studio or in the carriage of a transport vehicle, the folded lifting module 300 enables the vehicle to better adapt to space limitations, improves space utilization, facilitates the storage and transportation of the vehicle, and effectively solves the problem of large space occupation during the storage of traditional camera-assisted mobile vehicles.

[0228] Referring to Figure 14 , the storage method includes:

[0229] Step S100: Control the lifting module 300 and the lifting chain module 400 to drive the second storage platform 200 to descend relative to the first storage platform 100, so that the second storage platform 200 coincides with the first storage platform 100; after the camera-assisted mobile vehicle completes the shooting task, the operator sends a command to the system by operating a control device (this control device has various forms, which can be either a button integrated on the vehicle control panel, a remote controller, or even a remote control through a mobile phone APP control terminal) to start the motors of the lifting module 300 and the lifting chain module 400. For example, pressing the clearly marked "descend" button on the control panel, the control signal will be transmitted to the motor controller through a circuit or wireless transmission. After receiving the signal, the motor controller will immediately drive the motors of the lifting module 300 and the lifting chain module 400 to reverse, providing power for the descent of the second storage platform 200. As the motors reverse, the lead screw of the lifting module 300 starts to rotate in the reverse direction, and the nut seat connected to the second storage platform 200 moves slowly downward along the axial direction of the lead screw under the drive of the lead screw. At the same time, the motor of the lifting chain module 400 drives the chain to shorten, assisting the second storage platform 200 to descend from the other side to ensure the smoothness of the descent process. During the descent, the operator can observe the descent speed and position of the second storage platform 200 in real time through the control device. For example, the control device is equipped with a special display screen that can intuitively display the real-time height value of the second storage platform 200. The operator can, according to the actual situation, adjust the speed adjustment button on the control device to change the input voltage or current of the motor, thereby precisely controlling the rotation speed of the motor and further adjusting the descent speed of the second storage platform 200. When the second storage platform 200 approaches the first storage platform 100, in order to ensure safe and smooth coincidence, the operator appropriately reduces the descent speed to avoid collisions due to excessive speed. After the second storage platform 200 completely coincides with the first storage platform 100, the operator operates the control device again to send a stop command. After receiving the command, the motor controller will quickly control the motors of the lifting module 300 and the lifting chain module 400 to stop running, and the second storage platform 200 will immediately stop descending.

[0230] Step S200: Operate to disassemble and separate the lifting module 300 from the first storage table 100; before performing the disassembly and separation operation of the lifting module 300 from the first storage table 100, the operator needs to determine the corresponding disassembly operation method according to the connection structure type of the lifting module 300 and the first storage table 100. For example, for the first locking module 510 in the above embodiment, the specific operation method is that the operator controls the first locking module 510 to release the fixing restriction of the lifting module on the first storage table 100, so that the lifting module 300 can be separated relative to the first storage table 100. After the connection structure disassembly is completed, the operator manually lifts or pulls up the lifting module 300 to separate it from the first storage table 100.

[0231] Step S300: Operate the lifting module 300 to rotate relative to the second storage table 200 for horizontal folding to achieve storage. Before folding the lifting module 300, the operator needs to confirm whether the rotational connection structure between the lifting module 300 and the second storage table 200 is in a rotatable state. If there is a locking device, such as the second locking module 520 in the above embodiment, the operator first needs to operate the locking device to unlock. The specific operation method is that the operator controls the second locking module 520 to release the restriction on the rotation of the lifting module 300, so that the lifting module 300 can rotate freely relative to the second storage table 200. After unlocking, the operator firmly holds the lifting module 300 with both hands and pushes the lifting module 300 to rotate around the rotation connection point. During the rotation process, the operator needs to always pay attention to observing the rotation direction of the lifting module 300 and the surrounding environment to avoid the lifting module 300 colliding with other vehicle components or surrounding objects, causing equipment damage. As the lifting module 300 rotates, it gradually changes from the vertical working state to the horizontal folded state. During the folding process, the operator can flexibly adjust the rotation speed and angle according to the actual space situation to ensure that the lifting module 300 is successfully folded to the appropriate position. For example, if the surrounding space is narrow, the operator can slow down the rotation speed and carefully adjust the angle to ensure the safe folding of the lifting module 300. At this time, the photographic auxiliary mobile vehicle completes the storage operation, and the overall occupied space of the vehicle is significantly reduced, facilitating storage or transportation.

[0232] In addition, when the lifting module 300 rotates to the horizontal folded state, if the rotational connection structure is provided with a locking device, the operator operates the locking device again to lock the lifting module 300 in the folded position. For example, for a hinge with a locking pin 512, the operator inserts the locking pin 512 into the corresponding hole of the hinge to prevent the lifting module 300 from accidentally rotating during storage or transportation, ensuring the stability of the vehicle in the stored state.

[0233] The operation process of this storage method is simple and easy to understand. Operators can master it proficiently after simple training. Whether it is to control the lowering of the second storage table 200, or to disassemble and separate the lifting module 300 and fold the lifting module 300, each step has clear operation guidelines and fewer operation steps. For example, when controlling the lowering of the second storage table 200, only one button on the control device needs to be operated to start the lowering process. Compared with the traditional complex storage operations, the operation difficulty is greatly reduced, the operation efficiency is improved, and the possibility of human operation errors is reduced.

[0234] In some embodiments, referring to Figure 15 , step S200 includes:

[0235] Step S210: Control the manipulation component 513 to drive the sliding seat 511 to slide, so that the locking pin 512 exits the locking port 310K to unlock the mounting bracket 310; the operator performs corresponding operations according to the type of the manipulation component 513. If it is the rotating push frame 5132 mentioned in the above embodiments, the operator can step on the rotating push frame 5132 and step on the rotating push frame 5132 in the preset operation direction. For example, if the clockwise rotation of the rotating push frame 5132 is the unlocking direction, the operator steps on the rotating push frame 5132 clockwise. During the rotation process, the operator can feel the resistance change of the rotating push frame 5132, and judge whether the sliding seat 511 slides normally through experience or operation feedback (such as the set damping feeling, etc.). With the operation of the manipulation component 513, the sliding seat 511 slides smoothly under the guidance of the guiding structure (such as a guide rail, a chute, etc.). Since the sliding seat 511 is rigidly connected to the locking pin 512, the locking pin 512 moves synchronously with the sliding seat 511. When the stepping is in place, the locking pin 512 completely exits the locking port 310K, and the locking connection between the mounting bracket 310 and the first storage table 100 is released, and the mounting bracket 310 is in a separable state.

[0236] Step S220: Separate the mounting bracket 310 from the first storage table 100. After confirming that the mounting bracket 310 has been unlocked, the operator checks whether there are other connection or obstruction factors that may affect the separation between the mounting bracket 310 and the first storage table 100, such as whether there is a residual cable connection or other component interference. If so, the operator first performs corresponding processing, such as untying the cable connection or removing the interfering component. The operator holds the mounting bracket 310 with both hands and lifts the mounting bracket 310 upward with force. Since the locking pin 512 has exited the locking port 310K, the connection resistance between the mounting bracket 310 and the first storage table 100 is greatly reduced, and the operator can relatively easily separate the mounting bracket 310 from the first storage table 100. During the separation process, the operator needs to pay attention to keeping the mounting bracket 310 balanced to avoid tilting or dropping of the mounting bracket 310 due to uneven force, causing equipment damage or personal injury.

[0237] In some embodiments, referring to Figure 16 , before step S300, the storage method further includes:

[0238] Step S400: Press the unlocking pressing member 522 to cancel the hooked engagement between the locking hook 521 and the hook groove 210C to unlock the rotating seat 600. The operator locates the position of the unlocking pressing member 522 on the photographic auxiliary moving vehicle. The unlocking pressing member 522 is usually arranged at an easily operable position, such as a position on the second storage table 200 close to the rotating seat 600. A circular pressing button with an obvious mark is set as the unlocking pressing member 522 to facilitate the operator to quickly locate. The operator presses the unlocking pressing member 522 with a finger or an operating tool. During the pressing process, the operator can feel the change in the pressing resistance. As the pressing action progresses, the unlocking pressing member 522 contacts the locking hook 521 and transmits the pressing force to the locking hook 521 to push the locking hook 521 out of the locking groove 600C. When the locking hook 521 completely disengages from the hook groove 210C, the rotating seat 600 can rotate freely under an external force, providing conditions for subsequent storage operations, such as rotating relative to the second storage table 200 for horizontal folding, etc.

[0239] In some embodiments, referring to Figure 17 , before step S300, the storage method further includes:

[0240] Step S500: Control the movement of the abutting member 532 to loosen the locking tongue 531 and make the locking tongue 531 disengage from the locking groove 600C to cancel the driving connection between the lifting drive assembly 320 and the rotating seat 600. The operator locates the position of the abutting member 532 on the photographic auxiliary moving vehicle and pulls the abutting member 532 with a finger or an operating tool. As the pulling action progresses, the abutting member 532 loosens the abutment on the locking tongue 531. After the abutting member 532 loosens the locking tongue 531, the lifting drive assembly 320 drives the locking tongue 531 to move and disengage from the locking groove 600C. At this time, the driving connection between the rotating seat 600 and the lifting drive assembly 320 is cancelled, and the rotating seat 600 can move independently under other external forces (such as manual pushing for folding operations, etc.) and is no longer restricted by the direct driving connection of the lifting drive assembly 320.
