[0043] To facilitate understanding of the solution of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.

[0044] See also Figure 1 , Figure 1 : is a structural schematic diagram of a lifting structure 001 provided in an embodiment of the present application. An embodiment of the present application provides a lifting structure 001. The lifting structure 001 includes a lifting block 011. The lifting block 011 has an inner cavity 113, a first opening 111 and a second opening 112. The first opening 111 and the second opening 112 both connect the inner cavity 113 with the outside world. The first opening 111 and the second opening 112 are arranged at an angle, and one side of the first opening 111 is connected to one side of the second opening 112. The first opening 111 and / or the second opening 112 are configured to allow the mating head of the lifting tool to pass through the inner cavity 113, and the inner cavity 113 is configured to accommodate the mating head of the lifting tool. The cavity wall of the inner cavity is configured to cooperate with the end stop of the lifting tool 021 along a first direction. The first direction is parallel to the direction in which the first opening 111 is connected to the inner cavity 113.

[0045] During lifting, the first direction can be perpendicular to the horizontal plane. Accordingly, the first opening 111 is located on the side of the lifting block 011 facing away from the direction of gravity. In this case, the wall of the inner cavity 113 penetrated by the first opening 111 serves as the gravity-bearing portion. Alternatively, during lifting, the first direction can be parallel to the horizontal plane. Accordingly, the second opening 112 is located on the side of the lifting block 011 facing the direction of gravity. In this case, the lifting tool abuts the wall of the inner cavity 113 away from the second opening 112, serving as the gravity-bearing portion. Specifically, during lifting, the first direction is parallel to the horizontal plane.

[0046] It is understood that the lifting tool can be a hook, which can be a U-shaped or hook-shaped structure, with one end being a mating head that engages with the wall of the inner cavity 113, and the other end being connected to the lifting device, with the middle portion of the lifting tool near the mating head engaging with the first opening 111. In this case, the end of the lifting tool can enter the inner cavity 113 from the first opening 111, or from the second opening 112, or part of the lifting tool can enter the inner cavity 113 from the first opening 111 and the other part from the second opening 112. After the mating head enters the inner cavity 113, the lifting tool moves in a direction away from the second opening 112 until the mating head of the lifting tool engages with the wall of the inner cavity 113 along the first direction.

[0047] In addition, when the lifting structure 001 is applied to the box, it can be welded to the box, embedded in the box, or integrally formed with the box.

[0048] In this embodiment, the lifting structure 001 is provided for lifting, so that the lifting tool can be directly hung in the inner cavity 113, and the movement of the lifting tool in the first direction can be restricted by the cavity wall of the inner cavity 113, thereby improving the stability of the position of the lifting tool in the inner cavity 113 and avoiding unhooking; in this way, the lifting operation is simple and the coordination is reliable, thereby improving the lifting efficiency.

[0049] In addition, the provision of the first opening 111 and the second opening 112 connected thereto can increase the size of the entrance of the lifting tool into the inner cavity 113, thereby reducing the difficulty of installing the lifting tool into the inner cavity 113. In this way, the ease of lifting can be improved, thereby improving the lifting efficiency.

[0050] See also Figure 2 , Figure 2 It is a structural schematic diagram of another lifting structure 001 provided in an embodiment of the present application. In one embodiment, a third opening 114 is further provided on the lifting block 011 for connecting the inner cavity 113 with the outside world. The third opening 114 and the first opening 111 are arranged on the same side panel of the lifting block 011. The third opening 114 is located on the side of the first opening 111 away from the second opening 112. One side of the third opening 114 is connected to the first opening 111. Along the second direction, the first opening 111 has a first length dimension, and the third opening 114 has a third length dimension, and the third length dimension is smaller than the first length dimension. The second direction is perpendicular to the plane where the angle is located. The lifting tool includes a mating head and an arm body connected in sequence, and the third opening 114 is configured to mate with an end of the arm body close to the mating head.

[0051] It can be understood that, along the second direction, the third opening 114 is clearance-fitted with an end of the arm body close to the mating head.

[0052] Optionally, the lifting tool 021 is Figure 4The structure shown has an L-shaped main body, and a mating head 212 extending in a direction perpendicular to the L-shaped surface is provided at the end. The mating head 212 serves as a mating end, which is located in the inner cavity 113 and cooperates with the limit plate. The other end of the lifting tool 021 passes through the first opening 111 and is connected to the lifting device.

[0053] In which, along the second direction, the third opening 114 can be connected to the portion of the first opening 111 located at one end in the second direction, or to the middle portion of the first opening 111 located in the second direction, or to the portion of the first opening 111 located at the other end in the second direction.

[0054] In this embodiment, by providing the third opening 114 , the matching height between the lifting tool 021 and the lifting structure 001 can be reduced, thereby reducing the space requirement of the lifting structure 001 for the use environment, thereby improving the adaptability of the lifting structure 001 .

[0055] See also Figure 2 In one embodiment, along the second direction, the third opening 114 is connected to the middle portion of the first opening 111 .

[0056] In this way, the cavity walls on both sides of the inner cavity along the second direction cooperate with the lifting tool 021 to stop, so that the interaction points between the lifting tool 021 and the lifting structure 001 can be dispersed and the force can be more uniform, thereby improving its stress state and improving its structural reliability.

[0057] See also Figure 2 In one embodiment, at least one of the edges of the first opening 111 , the second opening 112 , and the third opening 114 is rounded.

[0058] Specifically, the edges of the first opening 111 , the second opening 112 , and the third opening 114 are all rounded.

[0059] In this embodiment, through the above-mentioned settings, on the one hand, stress concentration can be reduced, thereby improving the durability and reliability of the lifting structure 001; on the other hand, when the lifting structure 001 cooperates with the lifting tool 021, the movement of the lifting tool 021 can be guided, thereby improving the coordination between the lifting tool 021 and the lifting structure 001.

[0060] In one embodiment, the first opening 111 is configured to allow a mating head of the lifting tool 021 to penetrate into the inner cavity 113 or exit from the inner cavity 113 along a first direction.

[0061] It is understood that the end of the lifting tool 021 can be moved along the first direction through the first opening 111 to the inner cavity 113, and then moved upward in a direction away from the second opening 112 until the end of the lifting tool 021 is stopped and engaged with the wall of the inner cavity 113 along the first direction. The end of the lifting tool 021 away from the inner cavity 113 is connected to the lifting equipment.

[0062] In addition, the end of the lifting tool 021 can move toward the second opening 112 until the end of the lifting tool 021 moves to a height position opposite to the first opening 111, and then moves along the first direction through the first opening 111 to the outside of the inner cavity 113, thereby exiting from the inner cavity 113.

[0063] Compared to the arrangement in which the end of the lifting tool 021 enters the inner cavity 113 through the second opening 112, this embodiment allows the lifting tool 021 to enter or exit the inner cavity 113 through the first opening 111. This reduces the height required for the lifting tool 021 to move during installation and removal, thereby preventing interference between the lifting tool 021 and components at the bottom of the lifting structure 001, which could restrict its use. This expands the applicable scenarios of the lifting structure 001 and improves the smoothness of the installation.

[0064] In one embodiment, along the second direction, the first opening 111 has a first length dimension, and the second opening 112 has a second length dimension. The first length dimension is consistent with the second length dimension. The second direction is perpendicular to the plane where the angle is located.

[0065] In this embodiment, the above arrangement makes the surface of the hanging structure 001 regular, which can avoid stress concentration areas in the hanging structure 001 and improve the manufacturability of the hanging structure 001 and reduce its molding difficulty.

[0066] In one embodiment, the lifting block 011 is an integrally formed part.

[0067] Specifically, the hoisting structure 001 is formed by casting.

[0068] In this embodiment, by configuring the hoisting block 011 as an integrally formed part, the quality consistency of the hoisting structure 001 can be improved, thereby reducing residual stress after molding, thereby helping to improve the durability and reliability of the hoisting structure 001.

[0069] See also Figure 3 , Figure 3: is a structural diagram of a lifting assembly 002 provided in an embodiment of the present application. Accordingly, an embodiment of the present application provides a lifting assembly 002, which includes a lifting tool 021 and the aforementioned lifting structure 001. The lifting tool 021 includes an arm 211 and a mating head 212 connected in sequence. The arm 211 is L-shaped, and one end of the arm 211 is connected to the mating head 212. The mating head 212 is the end of the lifting tool 021. Figure 4 As shown, Figure 4 2 is a schematic diagram of the structure of the lifting tool 021 provided in an embodiment of the present application. The mating head 212 is installed in the inner cavity 113 and is engaged with the cavity wall of the inner cavity along a first direction.

[0070] In this embodiment, by adopting the aforementioned lifting structure 001, the lifting tool 021 can be directly hung in the inner cavity 113, and the movement of the lifting tool 021 in the first direction can be limited by the cavity wall of the inner cavity and the matching head 212, thereby improving the stability of the position of the lifting tool 021 in the inner cavity 113 and avoiding unhooking; in this way, the lifting operation is simple and the matching is reliable, thereby improving the lifting efficiency.

[0071] See also Figure 4 In one embodiment, along the second direction, the width of the mating head 212 is greater than the width of the arm 211. The second direction is perpendicular to the plane where the angle is located.

[0072] Specifically, one side of the arm 211 close to the mating head 212 is mated with the third opening 114 . The mating head 212 is located in the inner cavity 113 , and both sides of the end of the mating head extending beyond the arm 211 are in contact with two opposite walls of the inner cavity 113 .

[0073] In this embodiment, through the above arrangement, the lifting tool 021 has a portion that cooperates with the cavity wall of the inner cavity, and the overall structure is simple and easy to manufacture.

[0074] Specifically, the arm body 211 is provided with a matching hole 2111, and the arm body 211 is connected to the lifting equipment through the matching hole 2111. The matching hole 2111 is a mounting hole or a threaded hole.

[0075] See also Figure 5 , Figure 5 Schematic diagram of the structure of a box assembly 003 provided in an embodiment of the present application. Accordingly, an embodiment of the present application provides a box assembly 003, which includes a box body 031 and the aforementioned hanging structure 001. Box body 031 has a mounting cavity; there are multiple hanging structures 001, and multiple hanging structures 001 are arranged on the outer wall of box body 031.

[0076] It can be understood that the box can be a box for installing a battery module, or a box for thermal management of the battery 005, for example, the shell of a liquid cooling plate.

[0077] In this embodiment, by adopting the aforementioned lifting structure 001, the lifting tool 021 can be directly hung in the inner cavity 113, and the cavity wall of the inner cavity 113 and the matching head 212 can be used to stop and cooperate to limit the movement of the lifting tool 021 in the first direction, thereby improving the stability of the position of the lifting tool 021 in the inner cavity 113 and avoiding unhooking; in this way, the lifting operation of the box body is simple and the cooperation is reliable, thereby improving the lifting efficiency.

[0078] See also Figure 6 , Figure 6 yes Figure 5 In the enlarged view of point A, in one embodiment, a plurality of mounting grooves 311 are provided on the outer wall of the box body 031 , and a plurality of hoisting structures 001 are respectively provided in the plurality of mounting grooves 311 .

[0079] In this embodiment, by setting the lifting structure 001 in the installation groove 311, the external structure of the box can be made regular, which not only makes the appearance of the box component 003 neat and improves the overall aesthetics of the product, but also facilitates the arrangement of other components around the box component 003, thereby improving the space utilization around the box component 003.

[0080] See also Figure 6 In one embodiment, the outer wall of the box body includes a top wall, a bottom wall, and a plurality of peripheral side walls connected between the top and bottom walls. The mounting groove 311 is provided on the peripheral side wall of the box body. Along the third direction, the mounting groove 311 extends through the bottom wall on a side opposite the second opening.

[0081] In addition, a hanging structure 001 is provided on at least a pair of opposite peripheral side walls of the box body 031 , and there are multiple hanging structures 001 on each peripheral side wall.

[0082] In this embodiment, by passing the installation groove 311 through the bottom wall, on the one hand, more operating space can be provided for installing the lifting structure 001 to the installation groove 311 or maintaining the lifting block 011, thereby improving the flexibility of installation and maintenance of the lifting structure 001; on the other hand, the installation groove 311 can have a larger space to install a larger lifting structure 001, so that the material thickness of the lifting structure 001 is increased, thereby improving the strength of the lifting structure 001.

[0083] See also Figure 7 , Figure 73 is a side view of the cooperation between the hanging structure 001 and the mounting slot 311 provided in an embodiment of the present application. In one embodiment, along the third direction, the side of the hanging block 011 close to the bottom wall is arranged coplanar with the bottom wall.

[0084] In this embodiment, by arranging the lifting block 011 on one side close to the bottom wall and coplanar with the bottom wall, the lifting block 011 can also serve as the load-bearing part of the box assembly 003, so that the bottom of the box assembly 003 has a larger area, thereby reducing the gravity borne by the bottom wall of the box assembly 003, and further improving the stress state of the box assembly 003.
