In some embodiments, the first side baffle 210 and the second side baffle 310 may be located on opposite sides of the base plate 100 along its width direction.

[0030] The top baffle 320 has a plate-like structure. The top baffle 320 is connected to the free end of the second side baffle 310. In some embodiments, the top baffle 320 and the second side baffle 310 may form an L-shaped plate-like structure.

[0031] In some embodiments, the movable baffle includes an open state and a closed state.

[0032] When the movable baffle is in the closed state, the fixed baffle and the movable baffle form a closed receiving space, with the top baffle 320 located above the fixed baffle.

[0039] In some embodiments, at least one container 400 may be detachably connected to the base plate 100.

[0040] By employing a rotatable movable baffle, the top and one side of the carriage can be easily opened, facilitating the installation or removal of the container and providing sufficient space for container movement, thereby improving the efficiency of container installation or removal.

[0041] In some embodiments, a sealing strip may be provided between the fixed baffle and the movable baffle. When the movable baffle is in the closed state, the sealing strength between the fixed baffle and the movable baffle can be increased.

[0042] In some embodiments, at least one locking structure may be provided between the fixed baffle and the movable baffle.

[0043] When the movable baffle is in the closed state, the locking structure connects the fixed baffle and the movable baffle, thereby restricting the rotation of the movable baffle.

[0044] In some embodiments, when the drive structure stops running, the transmission chain can be locked, thereby locking the movable baffle.

[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, a support part 110 is provided on the side of the base plate 100 near the movable baffle.

[0046] When the movable baffle is in the open state, the support portion 110 can be used to support the second side baffle 310. The support portion 110 can limit the second side baffle 310, restricting the extreme angle of downward rotation of the second side baffle 310. In some embodiments, the support portion 110 may include various shapes, such as at least one of the following: strip-shaped, plate-shaped, cylindrical, etc.

[0047] By providing the support part 110, when the movable baffle is in the open state, the support part 110 provides support for the second side baffle 310, which can improve the stability and load-bearing capacity of the second side baffle 310.

[0048] In some embodiments, the support portion 110 is slidably disposed within the base plate 100. In some embodiments, the support portion 110 can be controlled to extend and retract via various structures, such as at least one of a hydraulic cylinder, a motor, an electric actuator, or a pneumatic cylinder. In some embodiments, multiple support portions 110 can be provided, and the multiple support portions 110 can be evenly distributed along the length direction of the base plate 100. In some embodiments, the multiple support portions 100 can be controlled individually. In some embodiments, the structure controlling the extension and retraction of the support portion 110 can be communicatively connected to a processor, thereby enabling remote and automated control of the support portion 110 using the processor.

[0049] By controlling the extension and retraction of the support part 110, the contact area between the support part 110 and the second side baffle 310 can be controlled, thereby changing the strength of the second side baffle 310 under support to meet various practical needs and improve the applicability of the support part 110.

[0050] In some embodiments, a support rod 321 is provided within the top baffle 320, and the support rod 321 is a telescopic structure.

When the movable baffle is in the open state, the support rod 321 can extend outward to contact the ground, providing support for the free end of the second side baffle 310, preventing the second side baffle 310 from forming a cantilever structure, and further improving the stability and load-bearing capacity of the second side baffle 310. In some embodiments, the support rod 321 can adopt various structures, such as at least one of the following: a piston rod of a hydraulic cylinder, a rack meshing with a gear, or a jack. In some embodiments, multiple support rods 321 can be provided, and the multiple support rods 321 can be evenly distributed along the length direction of the base plate 100.

[0051] Figure 3 This is a structural schematic diagram of the second side baffle according to some embodiments of this specification.

[0052] In some embodiments, such as Figure 2 , Figure 3 As shown, multiple guide rails 311 are provided on the inner side of the second side baffle 310.

[0053] The guide rail 311 is used to guide and restrict the movement direction of other structures. In some embodiments, the length direction of the guide rail 311 is perpendicular to the length direction of the base plate 100. In some embodiments, when the movable baffle is in the open state, the transport system can transport the container 400 above the second side baffle 310 and place the container 400 on the second side baffle 310. The transport system can then move the container 400 along the length direction of the guide rail 311 until it enters the receiving space. The guide rail 311 can be used to guide the movement of the container 400. In some embodiments, the distance between two adjacent guide rails can be greater than or equal to the width of the container 400 along the length direction of the base plate 100. In some embodiments, the distance between two adjacent guide rails 311 can be gradually varied. For example, along the direction of entering the receiving space, the distance between two adjacent guide rails 311 can gradually decrease, and the minimum distance between two adjacent guide rails 311 can be equal to the width of the container 400 along the length direction of the base plate 100, thereby enhancing the guiding effect of the guide rail 311 on the container 400.

[0054] The guide rail 311 can be used to position and guide the movement of the container 400, preventing the container 400 from colliding with the interior of the vehicle during installation. Keeping the movable baffle open increases the range of options for positioning the container 400, improving the flexibility of installation, reducing collisions, and increasing positioning efficiency.

[0055] In some embodiments, a plurality of rollers 312 are provided on the inner side surface of the second side baffle 310.

[0056] The roller 312 can convert sliding friction into rolling friction, thereby reducing the frictional force between the two structures. In some embodiments, the axis of the roller 312 is parallel to the length direction of the base plate 100. When the container 400 is placed on the second side baffle 310, the transport system continues to move the container 400, and the roller 312 can be used to reduce the resistance and wear of the container 400 during movement. In some embodiments, the roller 312 can be located inside the second side baffle 310. At least a portion of the roller 312 can extend beyond the side of the second side baffle 310, and the thickness of the portion of the roller 312 extending beyond the second side baffle 310 can be a preset value, such as 0.5 cm, 1 cm, or other values, and the specific value can be set according to actual needs. In some embodiments, the roller 312 can be made of steel to ensure its strength and prevent it from being crushed.

[0057] In some embodiments, the inner surface of the second side baffle 310 is provided with a plurality of first magnetic structures, and the bottom of the container 400 is provided with a plurality of second magnetic structures. The first magnetic structures 110 and the second magnetic structures can be connected by magnetic attraction.

[0058] In some embodiments, the first magnetic attraction structure 110 may include a permanent magnet. In some embodiments, the first magnetic attraction structure 110 may include an electromagnet. In some embodiments, the first magnetic attraction structure 110 may be communicatively connected to a processor, which may remotely and automatically control the first magnetic attraction structure 110 to generate or stop generating magnetic force. When the first magnetic attraction structure 110 generates magnetic force, it can attract a second magnetic attraction structure. Thus, when the transport system transports the container 400 to the area above the inner side of the second side baffle 310, the first magnetic attraction structure 110 can position and guide the container 400 by attracting the corresponding second magnetic attraction structure, avoiding the safety risks associated with manually adjusting the position of the container 400. Using the first magnetic attraction structure 110 to guide the positioning of the container 400 can also improve the positioning accuracy of the container 400 and the subsequent installation accuracy. In some embodiments, multiple first magnetic attraction structures 110 may be provided, for example, four, six, or other quantities, the specific number depending on actual needs. Multiple first magnetic attraction structures 110 may be evenly distributed in an array on the inner side of the second side baffle 310. The number of second magnetic structures is the same as that of the first magnetic structure 110, and their distribution can be the same.

[0059] In some embodiments, the second magnetic structure may include a permanent magnet or a magnetic metal, such as iron, nickel, etc.

[0060] In some embodiments, a plurality of first pressure sensors may be provided on the inner surface of the second side baffle 310, and the first pressure sensors can be used to detect pressure data. In some embodiments, the first pressure sensors can be communicatively connected to a processor. When the container 400 contacts the inner surface of the second side baffle 310, the first pressure sensors can detect pressure changes, and the processor can determine whether the container 400 is in contact with the second side baffle 310 based on the pressure changes detected by the first pressure sensors. In some embodiments, by providing a plurality of first pressure sensors, the processor can determine whether the container 400 is in stable contact with the second side baffle 310 based on whether the pressures detected by the plurality of first pressure sensors are uniform. After the container 400 is in stable contact with the second side baffle 310, the transport system then controls the container 400 to move into the receiving space. This ensures the accuracy and stability of the container installation.

[0061] Figure 4 This is a schematic diagram of the structure of the first positioning part and the second positioning part according to some embodiments of this specification.

[0062] In some embodiments, such as Figure 3 , Figure 4 As shown, the base plate 100 is provided with at least one first positioning part 120. The container 400 is provided with at least one second positioning part 410. The first positioning part 120 and the second positioning part 410 are adapted to each other.

[0063] The first positioning part 120 is used to limit the extreme positions of the movable container 400. In some embodiments, the first positioning part 120 may include at least one of various structures, such as a strip structure, a plate structure, a protruding structure, etc. In some embodiments, the first positioning part 120 may be connected to the base plate 100 in various ways, such as at least one of welding, snap-fit, threaded connection, integral molding, etc. In some embodiments, multiple first positioning parts 120 may be provided, and the multiple first positioning parts 120 may be evenly distributed along the length direction of the base plate 100.

[0064] The second positioning part 410 is installed in conjunction with the first positioning part 120 to improve the connection strength between the container 400 and the base plate 100, and to limit the relative movement and rotation of the container 400 and the base plate 100. In some embodiments, the first positioning part 120 and the second positioning part 410 can be engaged. In some embodiments, the second positioning part 410 may include a variety of structures, such as at least one of a protrusion, a groove, or a slot. In some embodiments, the first positioning part 120 may include an L-shaped protrusion, the vertical portion of which is connected to the base plate 100, and the horizontal portion which can be engaged with the second positioning part 120. In some embodiments, an elastic gasket may be provided between the first positioning part 120 and the second positioning part 120.

[0065] In some embodiments, a second pressure sensor may be provided on the first positioning part 120 and / or the second positioning part 120, and the second pressure sensor is communicatively connected to the processor. The processor can determine whether the container 400 is installed in place based on the pressure detected by the second pressure sensor. In some embodiments, one container 400 may correspond to multiple second pressure sensors, and the processor can determine whether the container 400 is installed in place based on whether the pressure detected by the multiple second pressure sensors is uniform. Whether the pressure detected by the multiple second pressure sensors is uniform means that the pressure detected by the multiple second pressure sensors is the same or the maximum difference in pressure is less than a difference threshold. The difference threshold is a preset value and can be set according to actual needs.

[0066] In some embodiments, such as Figure 3 As shown, the inner side of the top baffle 320 is provided with at least one pressing structure 322.

[0067] When the movable baffle is closed, the clamping structure 322 can be used to apply pressure to the container 400, improving the stability of the container 400. In some embodiments, the clamping structure 322 and the top baffle 320 can be connected in various ways, such as at least one of snap-fit, welding, threaded connection, and integral molding. In some embodiments, the clamping structure 322 can include various structures, such as at least one of a strip structure, a plate structure, and a protruding structure. In some embodiments, the clamping structure 322 can adopt an elastic structure, such as a spring, to avoid rigid contact between the clamping structure 322 and the container 400, which could damage the container 400. In some embodiments, the clamping structure 322 can include a telescopic structure, such as at least one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder, to adjust the pressure applied to the container 400 by controlling the extension and retraction of the clamping structure 322 as needed.

[0068] In some embodiments, when the movable baffle is in the closed state, the guide rail 311 can be used to press the container 400. This allows pressure to be applied to the container 400 from different directions, thereby further improving the stability of the container 400. In some embodiments, the portion of the guide rail 311 that contacts the container 400 can be elastic; for example, the portion of the guide rail 311 that contacts the container 400 can be provided with an elastic pad to prevent rigid contact between the guide rail 311 and the container 400, which could damage the container 400.
