[0070] In view of the shortcomings of the related technologies pointed out in the background art, this utility model embodiment proposes a photography auxiliary mobile cart that combines electric lifting function with convenient storage, thereby improving the storage convenience and practicality of the photography auxiliary mobile cart in actual shooting applications. It should be noted that the photography auxiliary mobile cart involved in this embodiment is not limited to the name "photography auxiliary mobile cart," and terms such as "director's cart" and "camera trolley" are also applicable.

[0071] Reference Figure 1 and Figure 2This application proposes a photography-assisted mobile vehicle, comprising:

[0072] First shelf 1;

[0073] The second shelf 2 is arranged at a vertical interval from the first shelf 1;

[0074] The lifting mechanism 3 is detachably mounted on the first shelf 1 and its output end is connected to the second shelf 2. The lifting mechanism 3 is used to drive the second shelf 2 to move closer to or further away from the first shelf 1.

[0075] The lifting mechanism 3, the first storage platform 1, and the second storage platform 2 can be configured as follows:

[0076] The lifting mechanism 3 is connected to the first shelf 1, and the lifting mechanism 3 is in a vertical unfolded state relative to the first shelf 1 and the second shelf 2; or, the lifting mechanism 3 is separated from the first shelf 1, and the lifting mechanism 3 is in a horizontal stacked state relative to the second shelf 2.

[0077] In this embodiment, the first platform 1 serves as the mounting base for the photography-assisted mobile vehicle and is typically located at the bottom of the vehicle. Wheels can be installed on its underside to enable the vehicle's mobility. The first platform 1 can hold photographic equipment. The second platform 2 is vertically spaced above the first platform 1 and can also be used to hold photographic equipment. The lifting mechanism 3 is detachably mounted on the first platform 1, and its output end is connected to the second platform 2, allowing the second platform 2 to move vertically closer to or away from the first platform 1.

[0078] Based on the following two configuration states, the working principle of the photography-assisted mobile vehicle of this application can be briefly described as follows:

[0079] Operating state: The lifting mechanism 3 is connected to the first shelf 1 and is in a vertically unfolded state. At this time, the lifting mechanism 3 is set in the vertical direction, supports the second shelf 2, and can adjust its height relative to the first shelf 1 by driving the second shelf 2 to meet the usage requirements.

[0080] Storage state: The second platform 2 can be driven by the lifting mechanism 3 to move towards the first platform 1. When the second platform 2 moves to the lowest position of the lifting mechanism 3, the lifting mechanism 3 can be separated from the first platform 1. At this time, the lifting mechanism 3 and the second platform 2 can be stacked together, so that the lifting mechanism 3, the second platform 2 and the first platform 1 are in a horizontal stacked state, which greatly reduces the overall height of the photography auxiliary mobile vehicle of this application and makes the structure more compact.

[0081] Compared to the rigid lifting structure using fixed lead screws or hydraulic rods in the prior art, this embodiment overcomes the problem of traditional designs being difficult to compress during storage by using a detachable lifting mechanism 3, thus achieving a dual optimization of functionality and portability.

[0082] The storage process of the photography-aided mobile cart in this application can be briefly described as follows:

[0083] First, when storage is needed, the lifting mechanism 3 lowers the second shelf 2 to its lowest position.

[0084] Then, the lifting mechanism 3 is separated from the first storage platform 1.

[0085] Finally, the lifting mechanism 3 is placed horizontally so that it is stacked horizontally with the second shelf 2.

[0086] The photographic auxiliary mobile vehicle of this application achieves the following beneficial effects through the above structural design:

[0087] Firstly, the height adjustment is convenient: the lifting mechanism 3 can drive the second shelf 2 to move up and down, allowing photographers to quickly adjust the height according to different shooting scenarios (such as shooting from high or low angles), thus improving work efficiency.

[0088] Secondly, by disassembling and separating the lifting mechanism 3 from the second storage platform 2, and placing the lifting mechanism 3 horizontally on the second storage platform 2, the height of the photography auxiliary mobile vehicle of this application is greatly reduced when not in use, achieving flat storage. This solves the problem of difficult storage of lifting structures such as lead screws and hydraulic rods in traditional designs, and significantly improves storage convenience.

[0089] In summary, the photography-aided mobile cart of this application, through the coordinated design of the first storage platform 1, the second storage platform 2, and the detachable lifting mechanism 3, successfully solves the problem of poor storage convenience in the prior art. Its working principle is based on the dual-state configuration of the lifting mechanism 3: it is vertically unfolded to adjust the height when in use, and horizontally stacked to compress space when stored, thus improving the storage convenience of the photography-aided mobile cart.

[0090] Reference Figures 1 to 3 In some embodiments, the lifting mechanism 3 proposed in this application includes a mounting frame 31, a lifting transmission assembly 32 disposed on the mounting frame 31, and a lifting drive assembly 33 disposed on the first storage platform 1.

[0091] The mounting bracket 31 is detachably connected to the first shelf 1, the lifting transmission assembly 32 is connected to the second shelf 2, and the lifting drive assembly 33 is used to drive the lifting transmission assembly 32 to move the second shelf 2 closer to or away from the first shelf 1.

[0092] In this embodiment, the lifting mechanism 3 of the photography-assisted mobile vehicle is further subdivided into three main components: a mounting frame 31, a lifting transmission assembly 32, and a lifting drive assembly 33. These components work together to achieve the height adjustment of the second platform 2 and the detachable storage function of the equipment. Its working principle is as follows:

[0093] Mounting bracket 31 serves as the basic frame of lifting mechanism 3 and is detachably connected to the first storage platform 1, providing support and positioning functions.

[0094] The lifting transmission assembly 32 is mounted on the mounting frame 31 and is directly connected to the second platform 2. It is responsible for transmitting the driving force to the second platform 2 so that it can move up and down.

[0095] The lifting drive assembly 33 is mounted on the first shelf 1 and serves as a power source to control the lifting of the second shelf 2 by driving the lifting transmission assembly 32.

[0096] Based on the following two configuration states, the working principle of the lifting mechanism 3 in this embodiment is as follows:

[0097] Operating state: When the mounting bracket 31 is fixedly connected to the first shelf 1, the lifting drive assembly 33 (e.g., a motor or manual crank) is activated, driving the lifting transmission assembly 32 (which may be a mechanical structure such as a gear set 133, a lead screw, or a chain) to operate. The lifting transmission assembly 32 transmits the driving force to the second shelf 2, causing it to move vertically closer to or away from the first shelf 1, thereby achieving height adjustment.

[0098] Storage state: When storage is required, the lifting drive assembly 33 drives the second shelf 2 to its lowest position. Subsequently, the mounting bracket 31 can be separated from the first shelf 1, and the lifting transmission assembly 32 together with the mounting bracket 31 can be horizontally stacked on the second shelf 2, reducing the overall height of the device.

[0099] Reference Figures 4 to 6 In some embodiments, the second shelf 2 proposed in this application is connected to a rotating seat 4, and the lifting drive assembly 33 is connected to the rotating seat 4 and can drive the rotating seat 4 to make the rotating seat 4 move the second shelf 2 closer to or away from the first shelf 1.

[0100] The mounting bracket 31 is slidably connected to the rotating seat 4 and can rotate relative to the second shelf 2 through the rotating seat 4, so that the lifting mechanism 3 is vertically unfolded or horizontally stacked relative to the second shelf 2.

[0101] In this embodiment, the lifting mechanism 3 of the photography-assisted mobile vehicle incorporates a rotating base 4 as an intermediate connecting component between the second storage platform 2 and the lifting mechanism 3, further optimizing the storage function. The working principle of the rotating base 4 is based on its coordinated operation with the lifting drive assembly 33, the second storage platform 2, and the mounting bracket 31, specifically:

[0102] The rotating base 4 is connected to the second shelf 2, and the lifting drive assembly 33 is connected to the rotating base 4. The lifting drive assembly 33 drives the rotating base 4 to move the second shelf 2 closer to or further away from the first shelf 1 to achieve the lifting function.

[0103] The mounting bracket 31 is slidably connected to the rotating seat 4, and the rotating seat 4 can rotate relative to the second shelf 2, thereby changing the posture of the lifting mechanism 3 relative to the second shelf 2.

[0104] Based on the following two configuration states, the working principle of this embodiment can be briefly described as follows:

[0105] Operating state: The lifting drive assembly 33 is activated, driving the rotating seat 4 to move. Since the rotating seat 4 is connected to the second shelf 2, it slides on the mounting bracket 31, thereby causing the second shelf 2 to move vertically closer to or further away from the first shelf 1, achieving height adjustment. It should be noted that in operating state, the rotating seat 4 slides linearly during lifting and lowering and does not rotate relative to the second shelf 2.

[0106] In the stowed state: The lifting drive assembly 33 drives the rotating seat 4 to move, causing the second shelf 2 to descend to its lowest position and then stop working. At this time, the mounting frame 31 can be separated from the first shelf 1, and then the rotating seat 4 can be driven to rotate relative to the second shelf 2 (for example, via a hinge or rotating shaft 81), so that the mounting frame 31 and the lifting mechanism 3 as a whole change from a vertical state to a horizontal state, that is, they are horizontally stacked with the second shelf 2. It should be noted that in the stowed state, the rotating seat 4 does not slide linearly relative to the mounting frame 31 during rotation.

[0107] In summary, the rotating seat 4 proposed in this embodiment is both a supporting component for the lifting drive and a key part for posture conversion. The second shelf 2 is raised and lowered through its connection with the lifting drive assembly 33, and the lifting mechanism 3 can switch from vertical to horizontal orientation through its rotational connection with the second shelf 2, thus balancing height adjustment functionality during use with compactness during storage.

[0108] Reference Figures 4 to 7 In some embodiments, the photography-assisted mobile vehicle proposed in this application further includes a first mating component 5 and a first locking mechanism 6. The first mating component 5 is disposed on the side of the second platform 2 facing the first platform 1, and the first locking mechanism 6 includes:

[0109] The second mating member 61 is movably connected to the rotating seat 4. The second mating member 61 is used to connect the first mating member 5 so that the rotating seat 4 is fixed relative to the second platform 2, or the second mating member 61 is used to separate from the first mating member 5 so that the rotating seat 4 is rotatable relative to the second platform 2.

[0110] In this embodiment, the first mating member 5 is disposed on the side (i.e., the lower side) of the second shelf 2 facing the first shelf 1, serving as a fixing or connection point. The first locking mechanism 6 includes a second mating member 61, which is movably connected to the rotating seat 4 and can be connected or separated from the first mating member 5.

[0111] The rotating seat 4 serves as an intermediate connecting component between the lifting mechanism 3 and the second platform 2, and its movement state (fixed or rotatable) is controlled by the first locking mechanism 6.

[0112] In the fixed state (usage state): the second mating component 61 is connected to the first mating component 5 (e.g., by means of a snap, pin, or magnetism), keeping the rotating seat 4 fixed relative to the second shelf 2. At this time, the rotating seat 4 cannot rotate, but can only slide along the mounting frame 31, cooperating with the lifting drive assembly 33 to drive the second shelf 2 to move vertically closer to or away from the first shelf 1, thereby achieving height adjustment.

[0113] In the rotatable state (storage state): the second mating component 61 separates from the first mating component 5, making the rotating seat 4 rotatable relative to the second shelf 2. At this time, after the mounting frame 31 separates from the first shelf 1, the rotating seat 4 can rotate, switching the mounting frame 31 and the lifting transmission assembly 32 from the vertical unfolded state to the horizontal stacked state, fitting against the second shelf 2.

[0114] Based on the above structural configuration, the first mating component 5 and the first locking mechanism 6 in this embodiment bring the following beneficial effects:

[0115] Stability in use: When the second mating component 61 is connected to the first mating component 5, the rotating seat 4 is locked in a fixed state and cannot rotate relative to the second platform 2. This locking mechanism ensures that the movement of the second platform 2 during lifting is limited to linear sliding in the vertical direction, avoiding instability or displacement caused by accidental rotation of the rotating seat 4, thereby ensuring the safety of the photographic equipment and the accuracy of shooting.

[0116] Flexibility in the stored state: When the second mating component 61 separates from the first mating component 5, the rotating seat 4 becomes rotatable, allowing the lifting mechanism 3 to change from a vertical to a horizontal position through the rotation of the rotating seat 4. This flexibility allows the device to quickly switch postures when stored, fitting snugly against the second shelf 2, achieving compact stacking and significantly reducing the overall height.

[0117] Please continue to refer to Figures 4 to 7 In some embodiments, the first mating component 5 proposed in this application includes a fixing frame 51, the fixing frame 51 having a hook groove 510, and the second mating component 61 includes a locking hook, the locking hook being rotatably connected to the rotating seat 4, the locking hook being used to form a hook engagement with the hook groove 510 to fix the rotating seat 4 relative to the second shelf 2 or to release the hook engagement with the hook groove 510 to allow the rotating seat 4 to rotate relative to the second shelf 2.

[0118] In this embodiment, the first mating component 5 (fixed frame 51) is disposed on the side of the second shelf 2 facing the first shelf 1, and has a hook groove 510. The hook groove 510 serves as a fixed force-bearing point and is used to form a mechanical connection with the locking hook.

[0119] The second mating component 61 (locking hook) is rotatably connected to the rotating seat 4 (which can be connected by a pin or hinge) and can rotate about the connection point. The design of the locking hook allows it to form a hook engagement or disengagement with the hook groove 510.

[0120] In the fixed state (usage state): The locking hook rotates until it aligns with and engages with the hook groove 510, forming a hook-holding engagement. At this time, the locking hook is restricted by the hook groove 510, and the rotating seat 4 cannot rotate relative to the second shelf 2; the rotating seat 4 can only slide along the mounting bracket 31. The rotating seat 4 is driven by the lifting drive assembly 33, causing the second shelf 2 to move vertically closer to or further away from the first shelf 1, thereby achieving height adjustment.

[0121] Rotatable state (storage state): The locking hook disengages from the hook groove 510, releasing the hook engagement (for example, the locking hook can be disengaged from the hook groove 510 by manually rotating the locking hook). At this time, the rotating base 4 loses its fixed constraint with the second shelf 2 and can rotate relative to the second shelf 2 via the hinge or rotating shaft 81. When the mounting bracket 31 separates from the first shelf 1, the rotating base 4 drives the lifting mechanism 3 to switch from the vertical unfolded state to the horizontal stacked state, fitting snugly against the second shelf 2.

[0122] Reference Figure 5 and Figure 7 In some embodiments, the photography-assisted mobile vehicle proposed in this application further includes an unlocking mechanism 7, which includes:

[0123] The unlocking press 71 is movably inserted into the second shelf 2 and aligned with the hook groove 510. The unlocking press 71 is used to move when subjected to external force to push the lock hook out of the hook groove 510.

[0124] The first elastic element has one end abutting against the second shelf 2 and the other end abutting against the unlocking press 71. The first elastic element is used to apply an elastic force to the unlocking press 71 to reset it.

[0125] In this embodiment, the unlocking press 71 is movably inserted into the second shelf 2 (exemplarily, it can be inserted into the second shelf 2 through a guide hole provided on the second shelf 2), and its position is aligned with the hook groove 510 to ensure that it can directly act on the lock hook in the hook groove 510. The design of the unlocking press 71 allows it to be displaced under external force (such as manual pressing), pushing the lock hook away from the hook groove 510. A first elastic member acts on the unlocking press 71, which may be a spring, elastic washer, etc., providing an elastic force to reset the unlocking press 71. At the same time, the first elastic member ensures that the unlocking press 71 maintains its initial position when no external force is applied, avoiding misoperation or accidental unlocking.

[0126] When it is necessary to switch the rotating seat 4 from a fixed state to a rotatable state, an external force (such as manual pressing by the photographer) is applied to the unlocking press 71. Upon receiving this external force, the unlocking press 71 moves along the movement path of the second shelf 2 (which may be perpendicular to the hook groove 510), applying a pushing force to the locking hook within the hook groove 510. This pushing force causes the locking hook to overcome the restriction of the hook groove 510 and be pushed out, thus releasing the hook engagement. At this point, the locking hook rotates and disengages due to the characteristics of the rotational connection, releasing the fixed constraint between the rotating seat 4 and the second shelf 2. The rotating seat 4 then becomes rotatable, allowing the lifting mechanism 3 to switch from a vertically unfolded state to a horizontally stacked state through the rotation of the rotating seat 4.

[0127] After the external force is removed, the first elastic element applies an elastic force to the unlocking press 71, causing it to move in the opposite direction and return to its initial position. The reset unlocking press 71 no longer exerts a pushing force on the lock hook, and the lock hook can be re-engaged with the hook groove 510 as needed (e.g., the photographer manually adjusts the lock hook to fit into the hook groove 510 during the next use).

[0128] Reference Figure 5 In some embodiments, the second shelf 2 proposed in this application embodiment has a clearance hole 20, the fixing frame 51 is located on one side of the clearance hole 20, and the mounting frame 31 can be inserted through the clearance hole;

[0129] The rotating seat 4 is rotatably connected to the second shelf 2 via a hinge 8. The hinge 8 includes a pivot 81 and a first page 82 and a second page 83 connected via the pivot 81. The first page 82 and the second page 83 are respectively connected to the second shelf 2 and the rotating seat 4. The pivot 81 is located in the clearance hole, and the diameter of the pivot 81 is greater than the depth of the clearance hole.

[0130] In this embodiment, the clearance hole 20 is formed in the second shelf 2, serving as a through hole to provide space for the rotation of the rotating seat 4 and the insertion of the mounting bracket 31. The fixing bracket 51 is located on one side of the clearance hole 20 (it can be near the edge or at a fixed position) and has a hook groove 510 for engaging with the locking hook to lock the rotating seat 4. The mounting bracket 31 can be inserted through the clearance hole 20 and slidably connected to the rotating seat 4, serving as a support structure for the lifting transmission assembly 32 and guiding the linear movement of the rotating seat 4 during lifting. It should be noted that when the mounting bracket 31 is horizontally stacked on the second shelf 2, the mounting bracket 31 is detached from the clearance hole 20. It is understood that the mounting bracket 31 only rotates relative to the second shelf 2 when the second shelf 2 is driven down to its lowest position; otherwise, the mounting bracket 31 may interfere with the clearance hole 20.

[0131] The hinge 8 includes a pivot 81 and a first page 82 and a second page 83 connected by the pivot 81: the first page 82 is fixedly connected to the second shelf 2. The second page 83 is fixedly connected to the rotating base 4. The pivot 81 is located inside the clearance hole 20, serving as the rotation axis 81 between the rotating base 4 and the second shelf 2. Its diameter is greater than the depth of the clearance hole 20 to ensure that when the mounting frame 31 and the lifting transmission assembly 32 rotate relative to the second shelf 2, the mounting frame 31 and the lifting transmission assembly 32 can be almost completely parallel to the second shelf 2 and stacked horizontally.

[0132] Reference Figure 5 In some embodiments, the rotating seat 4 proposed in this application is sleeved on the mounting frame 31, the mounting frame 31 is provided with a guide rail assembly 9, and the rotating seat 4 is connected to the slider of the guide rail assembly 9 so as to slide with the mounting frame 31.

[0133] In this embodiment, the guide rail assembly 9 typically includes a slide rail and a slider. The slide rail is disposed on the opposite side walls of the mounting frame 31. The adapter is sleeved on the mounting frame 31 and the slider is connected to the slide rail to achieve a sliding connection between the adapter and the mounting frame 31, so that the rotating seat 4 can slide along the guide rail on the mounting frame 31.

[0134] Reference Figure 5 and Figure 6 In some embodiments, a second locking mechanism 10 is provided between the lifting transmission assembly 32 and the rotating seat 4, the rotating seat 4 having a slot 401, and the second locking mechanism 10 including:

[0135] The locking tongue 1001 is connected to the lifting transmission assembly 32 and can move under the drive of the lifting transmission assembly 32 to enter or move away from the slot 401.

[0136] The abutment 1002 is movably disposed on the rotating seat 4. The abutment 1002 is used to drive the locking tongue 1001 to extend into or away from the slot 401, so as to restrict the locking tongue 1001 within the slot 401 or to separate the locking tongue 1001 so that the locking tongue 1001 can be dislodged from the slot 401.

[0137] The second elastic element 1003 acts on the abutment 1002, and the second elastic element 1003 is used to apply an elastic force to the abutment 1002 to reset it.

[0138] The lifting transmission assembly 32 is detachably connected to the rotating seat 4 by the locking tongue 1001 engaging with the slot 401, and can transmit driving power to the rotating seat 4.

[0139] In this embodiment, the rotating seat 4 is provided with a slot 401, which serves as the engagement point for the locking tongue 1001 and is used to connect with the lifting transmission assembly 32. The second locking mechanism 10 includes a locking tongue 1001, a holding member 1002, and a second elastic member 1003. The locking tongue 1001 is connected to the lifting transmission assembly 32 and can move (extend or move) under the drive of the lifting transmission assembly 32, entering or moving away from the slot 401 of the rotating seat 4. The holding member 1002 is movably disposed on the rotating seat 4 (possibly via a slide or hinge) to control the position of the locking tongue 1001, allowing it to extend into the slot 401 and lock, or to push it away from the slot 401 to unlock. The second elastic member 1003 acts on the holding member 1002 (possibly a spring, etc.), providing an elastic force to reset it.

[0140] The lifting transmission assembly 32 is engaged with the slot 401 of the rotating seat 4 via the locking tongue 1001, thereby achieving a detachable connection with the rotating seat 4 and transmitting lifting drive power to the rotating seat 4.

[0141] The working principle of the second locking mechanism 10 can be divided into the following two states:

[0142] In the locked state, the latch 1001 enters the slot 401: the lifting transmission assembly 32 drives the latch 1001 to move, causing it to extend into the slot 401 of the rotating seat 4. Under the elastic force of the second elastic member 1003, the holding member 1002 is in the initial position (reset state), which can apply a holding force to the latch 1001, restricting the latch 1001 within the slot 401 and preventing the latch 1001 from disengaging.

[0143] The locking tongue 1001 and the slot 401 engage to form a stable connection between the lifting transmission assembly 32 and the rotating seat 4. The driving force of the lifting transmission assembly 32 (which may be a lead screw, gear, or chain) is transmitted to the rotating seat 4 through the locking tongue 1001, causing the rotating seat 4 to slide along the mounting frame 31, thereby driving the second shelf 2 to rise and fall.

[0144] In the unlocked state, the latch 1001 can disengage from the slot 401: an external operation (such as manual pressing or pulling) acts on the abutment 1002, overcoming the resistance of the second elastic member 1003, causing the abutment 1002 to move (possibly by sliding or rotating). The abutment 1002 then moves the latch 1001 out of the slot 401. At this point, the latch 1001 can be disengaged from the slot 401, or it can be completely disengaged by manual adjustment.

[0145] After the locking tongue 1001 disengages from the slot 401, the connection between the lifting transmission assembly 32 and the rotating seat 4 is released, and the rotating seat 4 can move independently of the lifting transmission assembly 32 (for example, the rotation described above to achieve storage).

[0146] After the external operation is removed, the second elastic element 1003 drives the supporting element 1002 to reset to the initial position.

[0147] In summary, the working principle of the second locking mechanism 10 in this embodiment is based on the cooperation of the locking tongue 1001, the abutment 1002, and the second elastic element 1003. Driven by the lifting transmission assembly 32, the locking tongue 1001 enters the slot 401 of the rotating seat 4, engaging with the abutment 1002 to lock, thus achieving power transmission and connection. By operating the abutment 1002, the locking tongue 1001 disengages from the slot 401, releasing the connection, while the second elastic element 1003 ensures reset. This mechanism, through controllable engagement and disengagement, achieves a detachable connection and efficient power transmission between the lifting transmission assembly 32 and the rotating seat 4, providing reliable support for the lifting function and flexible posture transformation of the photography-assisted mobile vehicle.

[0148] Reference Figure 3 In some embodiments, the first shelf 1 proposed in this application has a first opening; the lifting transmission assembly 32 includes:

[0149] The screw 321 is fitted with a locking tongue 1001 and screwed to the screw 321. The screw 321 is rotatably connected to the mounting bracket 31, and one end of the screw 321 is exposed outside the mounting bracket 31 and extends through the first opening to the side of the first shelf 1 facing away from the second shelf 2 so as to be connected to the lifting drive assembly 33 for transmission.

[0150] In this embodiment, the first platform 1 has a first opening, which provides a path for the screw 321 to pass through, so that one end of the screw 321 can extend to the lower side of the first platform 1 and connect with the lifting drive assembly 33, ensuring the effective transmission of driving force while maintaining a compact structure.

[0151] The screw 321 is rotatably connected to the mounting bracket 31 (possibly via a bearing or a fixed seat) and is capable of rotating about its own axis. One end of the screw protrudes from the mounting bracket 31 and extends through a first opening to the side of the first shelf 1 facing away from the second shelf 2 (i.e., the bottom or lower side), and is drivenly connected to the lifting drive assembly 33 (e.g., a motor or handle).

[0152] The locking tongue 1001 is sleeved and screwed onto the screw 321, forming a threaded engagement with the screw 321, and can move axially along the screw 321. At the same time, it engages with the slot 401 of the rotating seat 4 (in conjunction with the aforementioned second locking mechanism 10) to transmit driving force.

[0153] Mounting bracket 31 provides a base for mounting and rotating screw 321.

[0154] The lifting drive assembly 33 (located below the first shelf 1) is connected to one end of the screw 321 via a first opening (possibly through gears, belts, or direct coupling), driving the screw 321 to rotate around its own axis. The locking tongue 1001 is screwed onto the screw 321 and, as the screw 321 rotates, moves axially along the screw 321 due to the thread action (up or down, depending on the direction of rotation). The locking tongue 1001 is fitted onto the screw 321 and engages with the slot 401 of the rotating seat 4 (through the cooperation of the second locking mechanism 10), converting the rotational motion of the screw 321 into the linear motion of the rotating seat 4. The rotating seat 4 slides along the mounting bracket 31 (in conjunction with the guide rail assembly 9), causing the second shelf 2 connected to it to move closer to or further away from the first shelf 1, thus achieving height adjustment.

[0155] Reference Figure 3 In some embodiments, the screw 321 provided in this application has a first helical gear 11 at one end exposed on the mounting bracket 31. The lifting drive assembly 33 is located on the side of the first shelf 1 facing away from the second shelf 2. The lifting drive assembly 33 includes a drive member 331, a first transmission rod 332 connected to the output end of the drive member 331, and a second helical gear 333 connected to the first transmission rod 332. The first helical gear 11 and the second helical gear 333 can be meshed.

[0156] In this embodiment, the screw 321 is rotatably connected to the mounting bracket 31, with one end exposed outside the mounting bracket 31 and passing through the first opening of the first shelf 1, extending to the side (i.e., the lower side) of the first shelf 1 facing away from the second shelf 2. The exposed end is provided with a first helical gear 11, which serves as the power input end.

[0157] The lifting drive assembly 33 is disposed on the side (lower side) of the first shelf 1 facing away from the second shelf 2, and includes:

[0158] Drive component 331: may be a motor, manual crank, or other power source that provides initial driving force.

[0159] First transmission rod 332: connected to the output end of drive component 331, transmitting driving force to gear.

[0160] The second helical gear 333 is connected to the first transmission rod 332 and can mesh with the first helical gear 11 to transmit rotational power.

[0161] When the drive unit 331 is activated, it (e.g., a drive motor or worm gear motor) operates, outputting rotational power to the first transmission rod 332. The two can be directly connected or connected via an intermediate transmission mechanism; this is only an example. The first transmission rod 332, driven by the drive, rotates the second helical gear 333. The second helical gear 333 meshes with the first helical gear 11, transmitting rotational power to the screw 321. The first helical gear 11 drives the screw 321 to rotate around its own axis. The rotation direction of the screw 321 depends on the output direction of the drive unit 331. When the screw 321 rotates, the locking tongue 1001, screwed to the screw 321, moves axially along the screw 321 due to the thread action (up or down, depending on the rotation direction). The locking tongue 1001 engages with the slot 401 of the rotating seat 4 (locked by the second locking mechanism 10), pushing the rotating seat 4 to slide along the guide rail assembly 9 of the mounting bracket 31. The rotating seat 4 drives the second shelf 2 to move closer to or further away from the first shelf 1, achieving height adjustment.

[0162] The meshing connection between the first helical gear 11 and the second helical gear 333 allows them to be separated when needed. When the mounting bracket 31 is separated from the first shelf 1, the screw 321 and its first helical gear 11 can be moved away with the lifting transmission assembly 32, and the second helical gear 333 is no longer engaged, thus achieving disassembly. For example, the mounting bracket 31 can be vertically pulled so that the screw 321 and the first helical gear 11 disengage from the first opening. At this time, the mounting bracket 31 and the lifting transmission assembly 32 can be rotated to be horizontally stacked on the second shelf 2.

[0163] Reference Figure 1 and Figure 8 In some embodiments, the photography-assisted mobile vehicle proposed in this application also includes an auxiliary lifting mechanism 13 that is horizontally spaced from the mounting frame 31. The output end of the auxiliary lifting mechanism 13 is connected to the second platform 2, which supports the second platform 2 and can move the second platform 2 closer to or away from the first platform 1.

[0164] In this embodiment, the photography-assisted mobile vehicle is equipped with an auxiliary lifting mechanism 13, which is horizontally spaced from the mounting frame 31. Its output end is connected to the second platform 2, supporting and driving the lifting and lowering of the second platform 2. Its working principle is based on the coordinated operation of the auxiliary lifting mechanism and the main lifting mechanism (driven by the screw 321 to rotate the seat 4), enhancing the stability and load-bearing capacity of the lifting function. The auxiliary lifting mechanism 13 has an output end that can abut against the second platform 2, providing additional support points. Together with the lifting transmission assembly 32 of the mounting frame 31, it shares the weight of the second platform and the photographic equipment on it. The horizontal spacing increases the distribution range of support. When the second platform carries heavy equipment, the auxiliary lifting mechanism shares the load of the main lifting mechanism (driven by the screw 321 to rotate the seat 4), reducing the stress on components such as the screw and rotating seat.

[0165] The auxiliary lifting mechanism 13 can move the second platform 2 closer to or further away from the first platform 1, and move synchronously with the main lifting mechanism (which drives the rotating seat 4 through the screw 321).

[0166] For example, when the screw 321 is driven to rotate, causing the locking tongue 1001 to move and drive the rotating seat 4 away from the first platform 1, the output end of the auxiliary lifting mechanism will move simultaneously, pushing the second platform 2 to move in the same direction; conversely, it will retract synchronously when descending.

[0167] In some embodiments, the auxiliary lifting mechanism may have an independent drive source (e.g., a hydraulic pump or a motor), but its operation is coordinated with the main lifting mechanism (which drives the rotating seat 4 via the screw 321) to ensure the smooth lifting and lowering of the second platform 2.

[0168] Reference Figure 3 , Figure 8 and Figure 9 In some embodiments, the first shelf proposed in this application has a through hole 103, and the auxiliary lifting mechanism 13 includes:

[0169] Box 131 is located on the first shelf 1;

[0170] The lifting chain 132 is vertically mounted on the box body 131 and connected to the second shelf 2;

[0171] Gear set 133 is provided in housing 131 and includes a first driven gear 1331 and a second driven gear 1332 that mesh with each other. The first driven gear 1331 is connected to the lifting chain 132. A portion of the second driven gear 1332 extends through the through hole 103 to the side of the first shelf 1 facing away from the second shelf 2.

[0172] The second transmission rod 134 has one end connected to the output end of the drive member 331 and the other end connected to the second driven gear 1332, so as to receive the driving power of the drive member 331 to drive the lifting chain 132, so that the lifting chain 132 drives the second platform 2 to move closer to or away from the first platform 1.

[0173] In this embodiment, the auxiliary lifting mechanism 13 is specifically defined as a structure including a housing 131, a lifting chain 132, a gear set 133, and a second transmission rod 134. It achieves lifting and lowering support for the second storage platform 2 through chain transmission and gear engagement. Its working principle is based on the cooperation of mechanical transmission and chain lifting, as detailed below:

[0174] The first shelf 1 has a through hole 103, serving as a channel for the second driven gear 1332 to pass through. The housing 131 is fixed to the first shelf 1, serving as a support and housing structure for the lifting chain and gear set. The lifting chain 132 is vertically mounted on the housing 131 and connected to the second shelf 2, responsible for transmitting lifting force. The gear set 133 includes a first driven gear 1331 and a second driven gear 1332 that mesh with each other. The first driven gear 1331 is driven by the lifting chain 132, pushing it to move. The second driven gear 1332 partially passes through the through hole 103 and extends to the underside of the first shelf 1. One end of the second transmission rod 134 is connected to the output end of the drive member 331, and the other end is driven by the second driven gear 1332 to transmit driving power. The drive member 331 outputs rotational power, which is transmitted to the second driven gear 1332 through the second transmission rod 134. The second driven gear 1332 rotates, driving the first driven gear 1331 to rotate in the same or opposite direction (depending on the gear design) through meshing. The first driven gear 1331 drives the lifting chain 132, causing the chain to rise and fall within the housing 131 (through meshing with a sprocket). The lifting chain 132 is connected to the second shelf 2, and its rising and falling causes the second shelf to move closer to or away from the first shelf 1.

[0175] Reference Figure 3 and Figure 8 In some embodiments, the photography-assisted mobile vehicle proposed in this application further includes a transmission mechanism 14, comprising:

[0176] The third helical gear 141 is disposed at a distance from the second helical gear 333 on the first transmission rod 332;

[0177] The fourth helical gear 142 is located on the second transmission rod 134 and meshes with the third helical gear 141;

[0178] The driving gear 143 is spaced apart from the fourth helical gear 142 on the second transmission rod 134 and meshes with the second driven gear 1332;

[0179] The first transmission rod 332 is connected to the output end of the drive member 331 via the third helical gear 141, the fourth helical gear 142, and the second transmission rod 134; the gear set is connected to the second transmission rod 134 via the drive gear 143 to the output end of the drive member 331.

[0180] In this embodiment, the transmission mechanism 14 includes a third helical gear 141, a fourth helical gear 142, and a driving gear 143. The transmission mechanism 14 transmits the power of the driving component 331 to the main lifting mechanism (lifting transmission assembly 32) and the auxiliary lifting mechanism 13 via the first transmission rod 332 and the second transmission rod 134, enabling the two to work together to drive the lifting of the second platform 2. Its operating principle is based on multi-stage gear transmission and power distribution, as detailed below:

[0181] The third helical gear 141 is spaced apart from the second helical gear 333 on the first transmission rod 332, receiving power from the drive member 331. The fourth helical gear 142 is located on the second transmission rod 134, meshing with the third helical gear 141 and transmitting power to the second transmission rod. The driving gear 143 and the fourth helical gear 142 are spaced apart on the second transmission rod 134, meshing with the second driven gear 1332 of the auxiliary lifting mechanism. The first transmission rod 332 is connected to the output end of the drive member 331 and has the second helical gear 333 (drive screw 321) and the third helical gear 141. The second transmission rod 134 is connected to the auxiliary lifting mechanism and has the fourth helical gear 142 and the driving gear 143. The drive member 331 provides a power source (such as a drive motor or worm gear motor). The second driven gear 1332 extends to the underside of the first platform through the through hole 103. The screw 321 is connected to the second helical gear 333 through the first helical gear 11.

[0182] The output end of the drive unit 331 drives the first transmission rod 332 to rotate. The second helical gear 333 on the first transmission rod 332 meshes with the first helical gear 11 on the screw 321, driving the screw 321 to move the locking tongue 1001 on it. The third helical gear 141 meshes with the fourth helical gear 142 on the second transmission rod 134, transmitting power to the second transmission rod 134. The second transmission rod 134 rotates, and its driving gear 143 meshes with the second driven gear 1332, driving the gear set 133 and the lifting chain 132 of the auxiliary lifting mechanism. The main lifting mechanism and the auxiliary lifting mechanism 13 synchronously drive the second platform 2 to rise and fall, which is stable and efficient.

[0183] Reference Figure 3 , Figure 9 and Figure 10 In some embodiments, the first shelf 1 proposed in this application embodiment is provided with a third locking mechanism 12 corresponding to the mounting frame 31. The third locking mechanism 12 is used to configure the mounting frame 31 and the first shelf 1 to be in a relatively fixed state or in a relatively movable state.

[0184] In this embodiment, the working principle of the third locking mechanism 12 is based on the switching of the following two states:

[0185] In a relatively fixed state (usage state): the third locking mechanism 12 is activated (e.g., by inserting a pin, tightening a bolt, or engaging a clip), fixing the mounting bracket 31 relatively to the first shelf 1. The mounting bracket 31 cannot move relative to the first shelf 1 (including translation or rotation), remaining stable. The lifting drive assembly 33 drives the rotating seat 4 to slide via the screw 321, causing the second shelf 2 to rise and fall. The third locking mechanism 12 ensures the structural rigidity throughout the process.

[0186] In a relatively movable state (storage or disassembly state): the third locking mechanism 12 is released (e.g., by pulling out the pin, loosening the bolt, or releasing the latch), thus releasing the fixed constraint between the mounting bracket 31 and the first shelf 1. The mounting bracket 31 becomes movable relative to the first shelf 1, and can be separated or its position adjusted. In this state, the mounting bracket 31 can be detached from the first shelf 1 and rotated or moved together with the lifting mechanism 3 (including the screw 321, the rotating seat 4, etc.), ultimately stacked horizontally with the second shelf 2 for storage.

[0187] Reference Figure 3 and Figure 10 In some embodiments, the mounting bracket 31 proposed in this application is provided with a locking slot 310, and the third locking mechanism 12 includes:

[0188] The slide 121 is located on the side of the first shelf 1 facing the second shelf 2 and is slidably connected to the first shelf 1;

[0189] The pin 122 is connected to the slide 121 and can be inserted into the lock 310 or separated from the lock 310.

[0190] The control component 123 is connected to the slide 121;

[0191] The control component is used to drive the slide 121 to slide, thereby driving the pin 122 to insert into the lock 310 or driving the pin 122 to separate from the lock 310, so that the mounting bracket 31 and the first shelf 1 are in a relatively fixed state or a relatively movable state.

[0192] In this embodiment, the third locking mechanism 12 of the photography-assisted mobile vehicle specifically includes a slide 121, a pin 122 and a control component 123. The mounting bracket 31 is provided with a locking slot 310, which serves as a fixed point for receiving the pin 122 to lock the mounting bracket 31.

[0193] The slide 121 is located on the side of the first shelf 1 facing the second shelf 2 (i.e., the upper side), and is slidably connected to the first shelf 1 (possibly via a slide rail or guide groove). A pin 122 is fixedly connected to the slide 121, moves with the slide 121, and can be inserted into or detached from the locking slot 310 of the mounting bracket 31. An operating component 123 is connected to the slide 121 and serves as a drive component; it may be a handle, lever, knob, or spring mechanism, used to drive the slide 121 to slide.

[0194] The third locking mechanism 12 operates based on the switching between the following two states:

[0195] In a relatively fixed state (usage state): the control component 123 drives the slide 121 to slide along the first shelf 1 (e.g., move towards the locking slot 310). The slide 121 drives the pin 122 to move, causing the pin 122 to insert into the locking slot 310 of the mounting bracket 31. The pin 122 and the locking slot 310 form a mechanical constraint, restricting the movement (including translation or rotation) of the mounting bracket 31 relative to the first shelf 1, thus achieving relative fixation between the two.

[0196] Relatively movable state (storage or disassembly state): The control component 123 drives the slide 121 to slide in the opposite direction (e.g., away from the lock 310). The slide 121 drives the pin 122 to move, causing the pin 122 to disengage from the lock 310 and separate from it. After the pin 122 disengages, the mounting bracket 31 loses its fixed constraint with the first shelf 1 and becomes relatively movable. The mounting bracket 31 can be separated from the first shelf 1 and rotate or move together with the lifting mechanism 3 (including the screw 321, rotating seat 4, etc.), and finally be stacked horizontally with the second shelf 2 to achieve storage.

[0197] In summary, the working principle of the third locking mechanism 12 in this embodiment is based on the cooperation of the slide 121, the pin 122, and the control component 123: the control component 123 drives the slide 121 to slide, causing the pin 122 to insert into the locking slot 310 of the mounting bracket 31 to lock the mounting bracket 31 to the first shelf 1, or to separate the pin 122 from the locking slot 310 to release the mounting bracket 31. The mechanical cooperation between the pin 122 and the locking slot 310 ensures stability during use, while the sliding design of the slide 121 provides operational flexibility.

[0198] Please continue to refer to Figure 3 and Figure 10 In some embodiments, the latch 122 proposed in this application is located on the side of the first shelf 1 facing away from the second shelf 2; the mounting bracket 31 is constructed with a locking part 311, and a lock 310 is formed in the locking part 311; the first shelf 1 is provided with a second opening 101, and the locking part 311 can pass through the second opening 101 and extend to the side of the first shelf 1 facing away from the second shelf 2;

[0199] The first shelf 1 is provided with a third opening 102 spaced apart from the second opening 101. The slide 121 includes a sliding part 1211 and an extension part 1212 connected to each other. The sliding part 1211 is located on the side of the first shelf 1 facing the second shelf 2 and is slidably connected to the first shelf 1. The extension part 1212 passes through the third opening 102 and extends to the side of the first shelf 1 facing away from the second shelf 2. The pin 122 is provided on the extension part 1212 to be aligned with the lock 310.

[0200] In this embodiment, the third locking mechanism 12 of the photography-assisted mobile vehicle further refines the structure and positional relationship of the pin 122, the slide 121, and the mounting bracket 31. Locking and releasing between the mounting bracket 31 and the first shelf 1 is achieved through the second opening 101 and the third opening 102. Its working principle is based on the mechanical cooperation of spatial layout and sliding locking, specifically as follows: The second opening 101 of the first shelf 1 allows the locking part 311 of the mounting bracket 31 to pass through, connecting the upper and lower sides. The third opening 102 of the first shelf 1 is spaced apart from the second opening 101, allowing the extension 1212 of the slide 121 to pass through. The mounting bracket 31 is constructed with a locking part 311, and a locking slot 310 is formed in the locking part 311. The locking part 311 can pass through the second opening 101 and extend to the lower side of the first shelf 1. The slide block 121 includes a sliding portion 1211 and an extension portion 1212. The sliding portion 1211 is located on the upper side of the first shelf 1 and is slidably connected to the first shelf 1 (possibly via a slide rail or guide groove). The extension portion 1212 passes through the third opening 102 and extends to the lower side of the first shelf 1. A pin 122 is disposed on the extension portion 1212, located on the lower side of the first shelf 1, and aligned with the locking slot 310 for inserting or disengaging the locking slot 310.

[0201] The third locking mechanism 12 operates based on the switching between the following two states:

[0202] In a relatively fixed state (usage state): The locking part 311 of the mounting bracket 31 passes through the second opening 101 of the first shelf 1 and extends to the lower side, with the locking port 310 aligned with the pin 122. The control component 123 drives the slide 121 to slide, for example, causing the pin 122 to move towards the locking port 310. At this time, the sliding part 1211 slides along the upper side of the first shelf 1. The extension part 1212 moves with the sliding part 1211, and through the third opening 102, it drives the lower pin 122 to insert into the locking port 310. The pin 122 enters the locking port 310, forming a mechanical constraint and restricting the movement of the locking part 311 (and the mounting bracket 31) relative to the first shelf 1.

[0203] In a relatively active state (storage or disassembly): the control component 123 drives the slide 121 to slide in the opposite direction, for example, away from the locking slot 310; the sliding part 1211 moves along the upper side of the first shelf 1. The extension part 1212 drives the pin 122 to exit the locking slot 310 through the third opening 102, separating from the locking slot 310. After the pin 122 disengages from the locking slot 310, the locking part 311 is unrestrained, and the mounting bracket 31 can move relative to the first shelf 1. The mounting bracket 31 can be separated from the first shelf 1, the locking part 311 exits through the second opening 101, and the rotating seat 4 rotates to drive the mounting bracket 31 and the lifting transmission component 32 to stack with the second shelf 2, achieving storage.

[0204] In summary, the working principle of the third locking mechanism 12 in this embodiment is based on the cooperation of the slide block 121, the pin 122 and the mounting bracket 31: the sliding part 1211 of the slide block 121 slides on the upper side, and drives the extension part 1212 through the third opening 102, which drives the lower pin 122 to insert or exit the lock 310; the locking part 311 of the mounting bracket 31 is aligned with the pin 122 through the second opening 101. When the pin 122 is inserted, it fixes the mounting bracket 31, and when it is separated, it releases the mounting bracket 31.

[0205] Please continue to refer to Figure 3 and Figure 10 In some embodiments, the slide 121 proposed in this application is provided with a receiving groove 1210, and the control component 123 includes:

[0206] Mounting base 1231 is set on the first shelf 1;

[0207] The rotating pusher 1232 is rotatably connected to the mounting base 1231. The rotating pusher 1232 is equipped with a push rod 1233, which is housed in the receiving groove 1210 so that the slide 121 and the rotating pusher 1232 form a linkage. The rotating pusher 1232 is used to rotate relative to the mounting base 1231 when subjected to external force so as to push the slide 121 to slide through its push rod 1233.

[0208] In this embodiment, the control component 123 in the third locking mechanism 12 of the photography-assisted mobile vehicle includes a mounting base 1231 and a rotating pusher 1232. By cooperating with the receiving groove 1210 of the slide block 121, it drives the slide block 121 to slide, thereby controlling the connection state between the pin 122 and the lock 310. Its working principle is based on the mechanical linkage conversion between rotation and sliding, as detailed below:

[0209] The slide 121 has a receiving groove 1210, which serves as a force-bearing groove and a semi-restrictive structure for connecting and accommodating the push rod 1233 of the rotating push frame 1232 and forming a linkage. The control assembly 123 includes a mounting base 1231 and a rotating push frame 1232. The mounting base 1231 is fixedly disposed on the side of the first shelf 1 facing the second shelf 2, serving as the rotation fulcrum of the rotating push frame 1232. The rotating push frame 1232 is rotatably connected to the mounting base 1231 (e.g., via a hinge or pivot 81), enabling it to rotate under external force, and is equipped with a push rod 1233. The push rod 1233 is accommodated in the receiving groove 1210 of the slide 121, forming a linkage with the slide 121.

[0210] The operating principle of the control component 123 is based on the process of the rotating pusher 1232 driving the slide block 121 to slide, thereby realizing the locking or disengagement of the latch 122 and the lock 310:

[0211] Locked State (Pin 122 inserted into lock slot 310): An external force (e.g., manual pressing or pulling) acts on the rotating pusher 1232, causing it to rotate relative to the mounting base 1231 (e.g., clockwise). As the rotating pusher 1232 rotates, the push rod 1233 moves within the receiving groove 1210, pushing the groove wall and causing the slide 121 to slide along the first shelf 1 (e.g., towards lock slot 310). The shape and size of the receiving groove 1210 limit the movement path of the push rod 1233, ensuring that the sliding direction of the slide 121 is controllable. The sliding of the slide 121 causes the pin 122 to insert into the lock slot 310 of the mounting bracket 31, fixing the mounting bracket 31 to the first shelf 1.

[0212] Unlocked state (pin 122 separated from lock 310): An external force causes the rotating pusher 1232 to rotate in the opposite direction (e.g., counterclockwise). The push rod 1233 moves in the opposite direction within the receiving groove 1210, pushing or pulling the slide 121 to slide along the first shelf 1 (e.g., away from the lock 310). The sliding of the slide 121 causes the pin 122 to disengage from the lock 310, and the mounting bracket 31 becomes movable relative to the first shelf 1. The mounting bracket 31 and the lifting transmission assembly 32 can be horizontally stacked with the second shelf 2.
