[0059] This utility model proposes a photography-assisted mobile vehicle, which is mainly used in photography and video equipment.

[0060] Reference Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the photography-assisted mobile vehicle includes:

[0061] First shelf 10;

[0062] The second shelf 20 is arranged vertically opposite to the first shelf 10;

[0063] A lifting device 30 is provided on the first shelf 10 and connected to the second shelf 20. The lifting device 30 is used to drive the second shelf 20 to rise or fall relative to the first shelf 10.

[0064] The battery module 40 is detachably mounted on the first shelf 10. The battery module 40 is electrically connected to the lifting device 30 and is used to supply power to the lifting device 30.

[0065] In this embodiment, the camera support mobile cart is a tool cart used to place and move camera equipment on the shooting location. The first platform 10 and the second platform 20 are mainly used to support camera-related equipment, and can simultaneously hold camera-related accessories, improving space utilization. These include spare lenses, tripod mounts, and small fill lights. For example, it could be a monitor for the director to watch the footage, or a camera for shooting. The first platform 10, as the main component of the camera support mobile cart, is thicker and larger than the second platform 20. Its function is to provide stable bottom support for the entire equipment. In actual use, the first platform 10 ensures that the equipment remains highly stable in various complex environments, guaranteeing the smooth progress of shooting.

[0066] In this embodiment, the lifting device 30 can be a hydraulic lifting platform. By installing hydraulic cylinders, mechanical pumps, and piping systems, the platform can be raised and lowered under the drive of the hydraulic cylinders. It can also be an electric screw type, a pneumatic lifting column type, or a scissor lift type. The structural form of the lifting device 30 can be selected according to actual needs and will not be elaborated further here. The lifting device 30 is located on the first storage platform 10 and connected to the second storage platform 20. Its main function is to drive the second storage platform 20 to rise or fall smoothly relative to the first storage platform 10, thereby adjusting the height of the second storage platform 20 to accommodate users of different heights taking and placing items from it. Simultaneously, the height between the first storage platform 10 and the second storage platform 20 can be adjusted according to the size of the photographic equipment placed on it, making full use of space while ensuring the overall stability of the photographic auxiliary mobile vehicle during movement. When not in use, the second storage platform 20 can be lowered to overlap with the first storage platform 10, thereby reducing the overall volume of the photographic auxiliary mobile vehicle for easy storage.

[0067] In this embodiment, the battery module 40 is detachably mounted on the first platform 10, providing power to the lifting device 30. It can independently power the lifting device 30 of the photography mobile auxiliary vehicle, supports quick replacement of the battery module 40, allowing users to easily replace batteries with insufficient power at any time. This ensures the continuous and stable operation of the lifting device 30 during shooting, preventing interruptions due to power problems and providing reliable power for photography work. Simultaneously, it allows the photography mobile auxiliary vehicle to operate continuously in outdoor locations or other places where charging is inconvenient, effectively improving the user experience.

[0068] In this embodiment, to ensure the movement of the camera-assisted mobile vehicle, the application further includes at least three wheels, which are rotatably mounted on the first platform 10. It is understood that the at least three wheels are rotatably arranged in a triangular array at the bottom of the first platform 10 to ensure the stability of the camera-assisted mobile vehicle. The wheels can be pushed to roll, thereby achieving manual movement of the camera-assisted mobile vehicle. Alternatively, the wheels can adopt a wheel structure with a motor hub to achieve automatic movement of the camera-assisted mobile vehicle under the action of electrical energy. The drive method of the wheels can be selected according to actual needs and will not be elaborated further here.

[0069] Reference Figure 3 and Figure 6 As shown, in one embodiment, the first shelf 10 is provided with a connecting seat 41;

[0070] The connector 41 has a connector groove 42;

[0071] The battery module 40 is provided with a connecting block 43, and the battery module 40 is inserted into the connecting slot 42 through the connecting block 43 to be detachably connected to the connecting seat 41.

[0072] In this embodiment, the first shelf 10 is provided with a connecting seat 41, which protrudes from the first shelf 10. The protruding surface has a connecting groove 42. The connecting seat 41 can be made of aluminum alloy and can be circular, rectangular, or similar in shape. For example, the connecting seat 41 is rectangular. The connecting seat 41 has two beveled corners on the edge side where the battery module 40 is inserted into the connecting seat 41, to prevent the battery module 40 from colliding with the corners and damaging it during installation, and to facilitate initial alignment during insertion. The connecting seat 41 has multiple hollowed-out openings on the surface avoiding the connecting groove 42, reducing its weight without affecting its strength. The connecting seat 41 also has protruding limiting parts 411, which are symmetrically arranged on both sides of the connecting seat 41 along the direction in which the battery module 40 is inserted into the connecting seat 41. These limiting parts can limit the horizontal insertion direction of the battery module 40 after it enters the connecting seat 41, preventing displacement of the battery module 40 in other horizontal directions.

[0073] In this embodiment, the connecting block 43 is detachably mounted on the battery module 40 via a threaded connection. It protrudes from the surface of the battery module 40 and engages with the connecting groove 42 to allow the connecting block 43 to slide within the groove. During insertion, the connecting block 43 on the battery module 40 is aligned with the connecting groove 42, and the battery module 40 is pushed horizontally into place along the groove 42. At this point, the battery module 40 is positioned between the two limiting portions 411, preventing it from shifting in any other horizontal direction.

[0074] Reference Figure 3 and Figure 4 As shown, in one embodiment, the connecting groove 42 is a wedge-shaped groove, and the connecting block 43 is a wedge-shaped block adapted to the wedge-shaped groove.

[0075] In this embodiment, the connecting groove 42 can be a wedge-shaped groove with a symmetrically inclined wedge structure. The inclination angle on both sides is 10 to 15 degrees, and the cross-section of the wedge-shaped groove is trapezoidal. The width of the groove bottom is slightly larger than the width of the groove opening, forming a self-locking inclined surface. The connecting block 43 is a wedge-shaped block that perfectly matches the wedge-shaped groove so that when the wedge-shaped block is inserted into the wedge-shaped groove, it can form a self-locking mechanism through the inclined surfaces on both sides of the wedge-shaped groove, restricting the movement of the battery module 40 in the vertical direction.

[0076] Reference Figure 4 and Figure 5 As shown, in one embodiment, the connector 41 is provided with a locking component 44 for locking the battery module 40, the groove wall of the connector 42 is provided with a clearance opening 45, the connector 43 is provided with a locking port 46, and the locking component 44 includes:

[0077] The unlocking operation component 47 is slidably connected to the connecting base 41. One end of the unlocking operation component 47 is provided with a locking part 48, and the other end of the unlocking operation component 47 is exposed outside the connecting base 41.

[0078] The elastic element 49 acts on the unlocking operation element 47, and the elastic element 49 is used to apply an elastic force to the unlocking operation element 47 to reset it.

[0079] The locking part 48 can move with the unlocking operation member 47 to enter the connecting groove 42 through the clearance opening 45 to form a snap-fit ​​with the locking port 46, or to release the locking fit with the locking port 46 and exit from the connecting groove 42 through the clearance opening 45.

[0080] In this embodiment, the unlocking operation member 47 is a metal rod-shaped structure that is slidably connected to the connecting seat 41. A slide rail adapted to the unlocking operation member 47 is formed on the surface of the connecting seat 41, allowing the unlocking operation member 47 to slide smoothly within the slide rail. One end of the unlocking operation member 47 has a locking part 48, which is a wedge-shaped protrusion. The other end of the unlocking operation member 47 passes through the side of the connecting seat 41 and protrudes outside the connecting seat 41, facilitating operation by the operator. The elastic member 49 can be a compression spring, with one end abutting against the end of the slide rail inside the connecting seat 41 and the other end abutting against the portion of the unlocking operation member 47 located inside the connecting seat 41. When the unlocking operation member 47 is pushed, the elastic member 49 is compressed, storing elastic potential energy; when the external force is removed, the elastic member 49 releases the elastic potential energy, pushing the unlocking operation member 47 to reset. An obstruction opening 45 is provided on the wall of the connecting groove 42. The size and position of the opening are adapted to the locking part 48 to ensure that the locking part 48 can pass smoothly. A corresponding locking opening 46 is provided on the connecting block 43. The locking opening 46 is a groove adapted to the wedge-shaped protrusion of the locking part 48.

[0081] In this embodiment, when the battery module 40 needs to be installed, the connecting block 43 on the battery module 40 is aligned with the connecting groove 42 on the connecting seat 41, and then the battery module 40 is pushed so that the connecting block 43 is inserted into the connecting groove 42. During the insertion process, the connecting block 43 will first contact the locking part 48 of the unlocking operation member 47. Since the locking part 48 is a wedge-shaped protrusion, the connecting block 43 will generate a lateral pushing force on the locking part 48, pushing the unlocking operation member 47 to slide into the connecting seat 41 against the elastic force of the elastic member 49, while the elastic member 49 is compressed. When the connecting block 43 is fully inserted into the connecting groove 42, the locking part 48 is aligned with the locking opening 46. At this time, the elastic member 49 releases its elastic potential energy, pushing the unlocking operation member 47 to reset, so that the locking part 48 enters the connecting groove 42 through the clearance opening 45 and forms a snap-fit ​​engagement with the locking opening 46, thereby firmly locking the battery module 40 onto the connecting seat 41. When the battery module 40 needs to be removed, the operator simply presses the end of the unlocking operation member 47 exposed outside the connector 41 towards the connector 41. Under the pressing action, the unlocking operation member 47 overcomes the elastic force of the elastic member 49 and slides into the connector 41. The locking part 48 then exits from the locking port 46 and moves out of the connecting groove 42 through the clearance opening 45, releasing the locking engagement with the locking port 46. At this time, the battery module 40 can be easily removed from the connector 41. When the hand is released, under the force of the elastic member 49, the locking part 48 moves back to the initial position, ready for the next locking. The locking assembly 44 described above enables convenient and quick installation and removal of the battery module 40, while ensuring that the battery module 40 does not shift horizontally, thus ensuring the stability and reliability of the battery module 40 during the operation of the photography-assisted mobile vehicle.

[0082] Reference Figure 5 As shown, in one embodiment, the connecting seat 41 includes a seat body 412 and a cover plate 413;

[0083] The seat 412 is provided with a sliding groove 414 that slides in cooperation with the unlocking operation member 47. The elastic member 49 is accommodated in the sliding groove 414, with one end of the elastic member 49 abutting against the groove wall of the sliding groove 414 and the other end abutting against the unlocking operation member 47.

[0084] The surface of the cover plate 413 away from the seat 412 has a connecting groove 42. The cover plate 413 is detachably connected to the seat 412 and covers the sliding groove 414.

[0085] In this embodiment, the surface of the seat 412 is provided with a horizontal groove 414, which has an open end and a closed end. The open end of the groove 414 is transitionally connected to the edge of the seat 412, allowing the unlocking operation member 47 to extend out of the connecting seat 41. The closed end of the groove 414 is located in the middle of the seat 412. The width and depth of the groove 414 are perfectly matched to the unlocking operation member 47, allowing the unlocking operation member 47 to move along it. One end of the elastic member 49 abuts against the closed end of the groove 414, and the other end abuts against the unlocking operation member 47. The cover plate 413 is detachably connected to the seat 412 by multiple evenly distributed bolts, and can completely cover the groove 414 on the seat 412, thus protecting the internal structure of the groove 414 and preventing dust and debris from entering.

[0086] Reference Figure 4 and Figure 5 As shown, in one embodiment, the width of the connecting groove 42 gradually decreases from large to small along the insertion direction of the connecting block 43.

[0087] In this embodiment, the width of the connecting slot 42 gradually decreases from large to small along the insertion direction of the connecting block 43. The wider inlet facilitates the initial alignment and insertion of the connecting block 43, reducing the alignment difficulty and time consumption during the installation process; the gradually decreasing slot width can effectively guide the connecting block 43, ensuring that the connecting block 43 is accurately inserted into the predetermined position, thus improving the success rate of installation. At the same time, it makes the removal of the battery module 40 smoother during disassembly.

[0088] Reference Figure 4 As shown, in one embodiment, the connecting seat 41 is detachably connected to the first shelf 10.

[0089] In this embodiment, the connecting seat 41 is provided with multiple countersunk bolt holes, evenly arranged on the surface of the connecting seat, and is detachably connected to the first platform 10 by bolts. Different models of connecting seats 41 can be replaced to accommodate battery modules 40 with different battery capacities. Furthermore, multiple connecting seats 41 can be provided to accommodate multiple battery modules 40. The multiple battery modules 40 are connected in parallel to power the lifting device. When one battery is low on power, it can be replaced individually without disconnecting the power supply to the lifting device 60, thus ensuring the stable operation of the photography-assisted mobile vehicle.

[0090] Reference Figure 2 As shown, in one embodiment, the battery module 40 is located on the side of the first shelf 10 away from the second shelf 20.

[0091] In this embodiment, the battery module 40 is suspended and fixed to the bottom of the first shelf 10 via the connecting base 41, making full use of the space at the bottom of the first shelf 10 and leaving storage space on the top surface of the first shelf 10. Simultaneously, the wedge-shaped groove design prevents the battery module 40 from moving vertically; the locking component 44 prevents it from moving horizontally; and the tapered connecting slot 42 shortens replacement time. This achieves efficient, convenient, and stable installation and fixing of the battery module 40, providing reliable protection for photographic work.

[0092] Reference Figure 2 As shown, in one embodiment, the lifting device 30 includes:

[0093] The lifting assembly 31 is installed on the first shelf 10 and connected to the second shelf 20;

[0094] The drive assembly 32 is disposed on the first shelf 10 and connected to the lifting assembly 31. The drive assembly 32 is used to drive the lifting assembly 31 to operate, so that the second shelf 20 rises or falls.

[0095] In this embodiment, the lifting assembly 31 can be composed of a lead screw, guide rod, and other structures. The lead screw is vertically mounted on the first platform 10 and fixed by bearings. The second platform 20 is sleeved on the lead screw, and the guide rod is set parallel to the lead screw and passes through the guide groove on the second platform 20. The drive assembly 32 can be composed of a motor, transmission assembly, and other structures. The motor drives the lead screw to rotate through the transmission assembly, causing the second platform to move in a straight line along the vertical direction, thereby driving the second platform 20 to rise or fall. Of course, the lifting assembly 31 can also be selected as a scissor-type lifting structure, which is composed of multiple sets of cross-hinged connecting rods. The bottom connecting rod is connected to the first platform 10 through a pivot, and the top connecting rod is connected to the second platform 20. A rotatable joint is provided at the intersection of each set of connecting rods to ensure that the connecting rods can move relative to each other. The drive assembly 32 can also be a hydraulic cylinder. When hydraulic oil is injected into the cylinder, the piston extends, pushing the scissor mechanism to unfold, causing the second platform 20 to rise; when the hydraulic oil is discharged, the piston retracts, the scissor mechanism contracts, and the second platform 20 descends. The drive form of the lifting assembly and drive assembly can be selected according to actual needs, and will not be elaborated further here.

[0096] Reference Figure 7 As shown, in one embodiment, the lifting assembly 31 includes:

[0097] The first lifting component 311 is detachably mounted on the first shelf 10 and connected to the second shelf 20. The first lifting component 311 can rotate relative to the second shelf 20 to perform horizontal folding or vertical unfolding.

[0098] The second lifting component 312 is disposed on the first shelf 10 and arranged at a distance from the first lifting component 311. The second lifting component 312 is connected to the second shelf 20.

[0099] In this embodiment, the first lifting component 311 is mounted above the first shelf 10 and connected to the second shelf 20. It is detachably connected to the first shelf 10, and the connection method includes, but is not limited to, snap-fit ​​connection and locking connection, which can be selected according to actual needs. For example, a locking device is provided between the two to lock and unlock the first lifting component 311. When the first lifting component 311 is vertically installed on the first shelf 10, it is locked by the locking device to ensure its stable fixation; after unlocking, the first lifting component 311 can be detached from the first shelf 10.

[0100] The first lifting component 311 and the second storage platform 20 can be rotatably connected or detachably connected. The first lifting component 311 rotates around the second storage platform 20 via a rotating structure to switch between vertical and horizontal states. For detachable connection, refer to the example of connection with the first storage platform 10, which will not be detailed here. Regardless of whether a rotatable or detachable connection is used, the first lifting component 311 can rotate relative to the second storage platform 20. When the vehicle is in use, it unfolds vertically to cooperate with the first storage platform 10 and the second storage platform 20 to realize the lifting function of the second storage platform 20. When the vehicle is stored, it folds horizontally to reduce space occupation. The first lifting component 311 can be a structural module with linear drive capability, such as a lead screw, synchronous belt, hydraulic cylinder, or linear motor. The specific selection depends on the actual needs, and this embodiment has no specific restrictions. Its quantity can be set to one or more according to the actual situation. If one is set, it is on one side of the front-rear direction of the photography-assisted mobile vehicle; if two are set, they are on both sides of the front-rear direction of the photography-assisted mobile vehicle. For example, one is located in front of the first storage platform 10, and the other is located in the rear. When the vehicle is stored, the two first lifting components 311 can be folded horizontally and stacked along the height of the photography-assisted mobile vehicle, or placed side by side along the left and right directions. The placement method is not limited.

[0101] The second lifting assembly 312 works in conjunction with the first lifting assembly 311 to support the second platform 20 and raise or lower it relative to the first platform 10, thus achieving flexible adjustment of the platform's height. For example, the second lifting assembly 312 is a drive component mainly composed of a chain, which controls the change in the chain's extension length to move the second platform 20 and achieve lifting. At least one second lifting assembly 312 is required; it can be individually installed on the edge of the photography-assisted mobile vehicle or spaced apart from the first lifting assembly 311, without affecting the central storage capacity while making the lifting of the second platform 20 more stable.

[0102] In one embodiment, the first lifting assembly 311 includes:

[0103] The mounting bracket is connected to the first shelf 10;

[0104] A lifting drive assembly is mounted on the mounting frame and connected to the second shelf 20;

[0105] The lifting drive assembly supports the second shelf 20 and can drive the second shelf 20 to rise or fall relative to the first shelf 10.

[0106] In this embodiment, the mounting frame is a frame structure with a certain height, used to support other components of the first lifting assembly 311, such as the lifting drive assembly. The first lifting assembly 311 is detachably connected to the first shelf 10 via its mounting frame, and is detachably mounted on the first shelf 10. For example, the bottom of the mounting frame abuts against the first shelf 10 and is detachably connected to the first shelf 10. The detachable connection method can be a snap-fit ​​connection, a locking connection, etc., as exemplified in the previous embodiments. Furthermore, the mounting frame as a whole can be inserted through the second shelf 20, or it can be located on the outside of the second shelf 20.

[0107] The lifting drive assembly is mounted on the mounting frame and connected to the second platform 20, and its function is to drive the second platform 20 to rise or fall. The lifting drive assembly can be a lifting device, a hydraulic cylinder, or a lead screw, etc. For example, the lifting drive assembly includes a lead screw, the lead of which is rotatably mounted on the mounting frame. A nut seat on the lead screw is connected to the second platform 20. When the lead screw is driven by a motor, the lead screw rotates accordingly, the nut seat moves on the lead screw, and thus drives the second platform 20 to move to rise or fall. The motor involved can be directly fixed to the mounting frame to connect with the lead screw, or the motor can be mounted on the second platform 20 and connected to the lead screw via an intermediate transmission structure (such as a transmission rod, bevel gear assembly, etc.).

[0108] In one embodiment, the second lifting assembly 312 includes:

[0109] The box body is connected to the first shelf 10;

[0110] A lifting chain is mounted on the box body and connected to the second shelf 20;

[0111] The gear set is located in the housing and is connected to the lifting chain drive. The gear set is used to receive driving power to drive the lifting chain, so that the lifting chain drives the second platform 20 to rise or fall.

[0112] In this embodiment, the gear set receives driving power and, through its own gear transmission structure, converts the power into a driving force for the lifting chain to rise or fall, thereby causing the lifting chain to raise or lower the second platform 20. For example, after receiving driving power, the driving gear in the gear set begins to rotate under the action of the driving power. The driving gear, through precise meshing with the driven gear, transmits the rotational motion to the transmission gear connected to the lifting chain. As this transmission gear continues to rotate, the lifting chain rises or falls along a predetermined track within the housing, directly driving the second platform 20 to rise or fall relative to the first platform. During this process, the precise transmission of the gear set ensures the smoothness and accuracy of the lifting chain's movement, ultimately achieving flexible and stable adjustment of the platform height.

[0113] In this embodiment, the box is used to accommodate the lifting chain, so that the chain can enter the box in an orderly manner when it is stored, so as to achieve recycling. The entire second lifting assembly 312 has a compact structure and does not occupy too much space.

[0114] Reference Figure 7 As shown, in one embodiment, the driving component 32 includes:

[0115] A drive motor 321 is installed on the first shelf 10;

[0116] A transmission component 322 is disposed on the first shelf 10. The transmission component 322 has a power input end and multiple power output ends.

[0117] The power input end is connected to the power output part of the drive motor 321, and the power output end is connected to the power input part of the lifting assembly 31.

[0118] In this embodiment, a drive motor 321 is disposed on the first shelf 10 and is connected to the lifting assembly 31. The drive motor 321 serves as a power output source, driving the lifting assembly 31 to provide power support for the lifting of the second shelf 20. The output shaft of the drive motor 321 is connected to a transmission assembly 322, which is connected to the lifting assembly 31. The transmission assembly 322 can be a gear, belt, or similar component. Corresponding to the drive motor 321, the power input end of the transmission assembly 322 is connected to the power output end of the drive motor 321. Similarly, corresponding to the first lifting assembly 311 and the second lifting assembly 312, each power output end of the transmission assembly 322 is connected to the power input end of the first lifting assembly 311 and the second lifting assembly 312. When the drive motor 321 is running, its power output section outputs driving power, which is transmitted to the transmission component 322 via the power input end of the transmission component 322, driving the transmission component 322 to run. At the same time, each power output end of the transmission component 322 transmits driving power to the power output section of the first lifting component 311 or the second lifting component 312 connected to it, causing the lifting component 31 to run. This achieves precise and synchronous driving of the first lifting component 311 and the second lifting component 312.

[0119] In one embodiment, the transmission assembly 322 includes:

[0120] The transmission rod passes through and is connected to the power output section of the drive motor 321; the opposite ends of the transmission rod are respectively connected to the second lifting assembly 312.

[0121] The driven rod is connected at one end to the transmission rod and at the other end to the first lifting assembly 311.

[0122] In this embodiment, a single transmission rod can be configured, which is connected to the drive motor 321. The middle end of the transmission rod corresponds to the power input end, and the two opposite ends of the transmission rod correspond to the two power output ends, respectively connected to the power input parts of the two second lifting components 312. Two driven rods can be configured, symmetrically arranged on both sides of the power output part of the drive motor 321. One end of the driven rod is connected to the transmission rod via a bevel gear transmission, and the other end is connected to the power input part of the first lifting component 311 via a bevel gear transmission.

[0123] When the drive motor 321 is working, its power output section outputs driving power, which is transmitted through the power input end of the transmission rod, driving the transmission rod to move. The power output end of the transmission rod correspondingly transmits the driving power to the power input section of the second lifting assembly 312 connected to it, causing the second lifting assembly 312 to move. At the same time, the transmission rod transmits power to the driven rod through the bevel teeth, driving the driven rod to rotate. The power output end of the driven rod transmits the driving power to the power input section of the first lifting assembly 311 connected to it. In this embodiment, through the coordinated connection of the transmission rod and the driven rod with each assembly, precise synchronous driving of the first lifting assembly 311 and the second lifting assembly 312 is achieved.

[0124] In one embodiment, the lifting device 30 further includes: a connecting wire body connected to the drive component 32, the connecting wire body having a power connection end for plugging into the battery module 40 so that the battery module 40 supplies power to the drive component 32.

[0125] In this embodiment, the connecting wire is used to connect the battery module 40 and the drive assembly 32. It possesses a certain degree of flexibility, allowing it to adapt to different bending angles without damaging the internal wires due to bending. This ensures the stable operation of the drive assembly 32. For example, when shooting in confined spaces, the moving vehicle needs to frequently turn or adjust its angle; the flexibility of the connecting wire allows it to bend freely with the movement of the moving vehicle, maintaining smooth power transmission. Furthermore, the connecting wire is wear-resistant, reducing the risk of leakage or open circuit due to wear, thus ensuring the normal power supply to the lifting device 30. For example, when shooting outdoors, the connecting wire may be dragged in environments such as grass; a wear-resistant connecting wire can prevent damage from such friction. Various types of existing insulated cables can be used for the connecting wire; for example, rubber-insulated wire can be used, selected according to actual needs, which will not be elaborated further here.

[0126] In this embodiment, the power connector of the connecting cable is designed as a plug that is compatible with the battery module 40, improving portability and allowing photographers to quickly plug and unplug the connector when changing the battery module 40. Different battery modules 40 may have different interface specifications, and the compatible plug design ensures that the connecting cable can be accurately connected to various battery modules 40 to achieve power transmission.
