[0037] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0038] In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, top, and bottom" are defined based on the orientation of the spreader tooling. "Inside" and "outside" are defined based on the inherent contours of the corresponding component. Terms such as "first" and "second" used in this disclosure are intended to distinguish one element from another and do not convey sequential or significant meanings. Furthermore, when the following description refers to the accompanying drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements.

[0039] See also Figure 1 、 Figure 2 、 Figure 9 and Figure 10 , the embodiment of the present disclosure provides a lifting fixture for a battery box, the battery box 10 may be provided with a plurality of slots 11, and the plurality of slots 11 may be symmetrically arranged on the opposite side walls of the battery box 10. The battery box 10 is a prior art and will not be described in detail here. In this embodiment, the battery box 10 may be a battery box 10 for a pure electric vehicle. Of course, in other embodiments, the battery box 10 may be a battery box 10 for a hybrid vehicle. The lifting fixture may include a beam 100 and a suspension member 200. Among them, the beam 100 can be used to be hung with a hook of a crane. The number of the suspension member 200 may be multiple, and may be arranged one-to-one corresponding to the plurality of slots 11. One end of the suspension member 200 may be configured with a detachable mortise and tenon connection with the beam 100, and the other end is used to be rotatably inserted into the slot 11.

[0040] It can be understood that when the battery box 10 needs to be hoisted and transported, one end of the suspender 200 is inserted into the slot hole 11, and the insertion of the two is easy to achieve, relatively simple, convenient for the transportation of the battery box 10, reduces the labor intensity of workers in the transportation process of the battery box 10, and improves the production efficiency. The setting of multiple groups of slot holes 11 and suspenders 200 can improve the stability and reliability of the transportation process of the battery box 10, and ensure that the battery box 10 can be hoisted and transported more easily. After the end of the suspender 200 is inserted into the slot hole 11, the crane moves the beam frame 100 to the suspender 200, and the end of the suspender 200 away from the slot hole 11 is connected with the beam frame 100 in a mortise and tenon joint, which ensures that the suspenders 200 located on the opposite two side walls of the battery box 10 can be connected with the beam frame 100 and inserted into the slot hole 11, thereby ensuring that each suspender 200 can provide stable support force for the upper hole wall of the slot hole 11.

[0041] In an embodiment, referring to Figures 3 to 5 , the beam frame 100 can include a first cross beam 120 and a longitudinal beam 130. The first cross beam 120 can be provided with a hanging hole 110 for hanging connection of a lifting hook. The number of longitudinal beams 130 can be half of the number of suspenders 200, and the plurality of longitudinal beams 130 can be arranged at intervals along the length extension direction of the first cross beam 120, and are respectively detachably connected with the suspender 200 and the first cross beam 120 in a mortise and tenon joint. The mortise and tenon joint can make the connection of the longitudinal beam 130 with the suspender 200 and the first cross beam 120 more firm.

[0042] It can be understood that, for example, the number of slot holes 11 can be four, and therefore the number of suspenders 200 can be four, and the number of longitudinal beams 130 can be two. The user inserts one end of the first suspender 200 into the first slot hole 11, rotates the first suspender 200 to make it stand upright, and when the crane drives the beam frame 100 to the suspender 200, the end of the suspender 200 away from the slot hole 11 is connected with one side of the first longitudinal beam 130 in a mortise and tenon joint. Then, the second suspender 200 located on the opposite side of the first suspender 200 is inserted into the second slot hole 11, the second suspender 200 is rotated to make it stand upright, and the second suspender 200 is connected with the side of the first longitudinal beam 130 away from the first suspender 200 in a mortise and tenon joint, that is, the opposite two suspenders 200 share one longitudinal beam 130. Similarly, the third suspender 200 and the fourth suspender 200 are connected with the second longitudinal beam 130 in a mortise and tenon joint. Of course, in other embodiments, the number of slot holes 11 can be six, and therefore the number of suspenders 200 is also six, and the number of longitudinal beams 130 is three.

[0043] In an embodiment, referring to Figure 3 and Figure 4The number of the longitudinal beams 130 can be two, the middle part of the longitudinal beam 130 can be provided with a first tenon groove 132, and the two ends of the first cross beam 120 can be formed with first tenon heads 121 which are inserted into the first tenon groove 132. Because the first tenon groove 132 is arranged in the middle part of the longitudinal beam 130, the first cross beam 120 can drive the two ends of the longitudinal beam 130 to move synchronously, so that the two suspension members 200 located on both sides of the longitudinal beam 130 can move synchronously, thereby ensuring the stability of the battery box 10 during the transfer process.

[0044] In an embodiment, referring to Figure 2 and Figure 4 , the upper end of the suspension member 200 can be provided with a insertion hole 210, and the longitudinal beam 130 can be provided with a limiting groove 131 which is open upward, and the end of the longitudinal beam 130 can pass through the insertion hole 210, so that the suspension member 200 is hung on the limiting groove 131 through the insertion hole 210.

[0045] It can be understood that the crane transfers the cross beam to the insertion hole 210 of the suspension member 200, the user pushes the suspension member 200 inward, so that the end of the longitudinal beam 130 can pass through the insertion hole 210, and then the end of the suspension member 200 can reach the limiting groove 131, the crane can lift the cross beam upward, so that the end of the suspension member 200 away from the slot hole 11 is clamped with the limiting groove 131, avoiding the suspension member 200 sliding relative to the cross beam during the movement of the battery box 10, thereby ensuring the stability and reliability of the battery box 10 during the transfer process.

[0046] In an embodiment, referring to Figure 2 , the opening of the limiting groove 131 can be designed as a trumpet shape which is gradually expanded from bottom to top. If the end of the suspension member 200 away from the slot hole 11 is not aligned with the opening of the limiting groove 131, the inclined surface of the trumpet shape can give the suspension member 200 an inward or outward force during the upward lifting of the longitudinal beam 130, so that the end of the suspension member 200 away from the slot hole 11 corresponds to the opening of the limiting groove 131 in the height direction, thereby ensuring that the suspension member 200 can be quickly clamped with the limiting groove 131, and improving the lifting efficiency of the battery box 10.

[0047] In an embodiment, referring to Figure 2 and Figure 4 , the number of the limiting grooves 131 can be multiple, and can be arranged at intervals along the length direction of the longitudinal beam 130. The user can select one of the multiple limiting grooves 131 to clamp the end of the suspension member 200 according to the size of the battery box 10, and by arranging multiple limiting grooves 131 on the longitudinal beam 130, the lifting tool can be used to lift and transfer different models of battery boxes 10.

[0048] In an embodiment, referring to Figure 3The beam frame 100 can further include a second cross beam 140 arranged inside the limiting groove 131, so as to avoid the second cross beam 140 interfering with the clamping of the limiting groove 131 and the suspension piece 200. Here, the inside is relative to the edge, and specifically refers to the limiting groove 131 being closer to the edge than the second cross beam 140, and the second cross beam 140 being closer to the inside than the limiting groove 131. The number of the second cross beam 140 can be two, and the two second cross beams 140 are arranged at two sides of the first cross beam 120 along the extending direction of the longitudinal beam 130. The two ends of the second cross beam 140 can be tenon-and-mortise connected with the two longitudinal beams 130 respectively, and the two ends of the second cross beam 140 can support the two ends of the longitudinal beam 130, so as to avoid the two ends of the longitudinal beam 130 being bent and deformed during the lifting of the suspension piece 200 and the battery box 10, and ensure the stability and reliability of the lifting of the battery box 10.

[0049] In an embodiment, referring to Figure 4 and Figure 6 , the longitudinal beam 130 can further be provided with a second mortise groove 133 arranged inside the limiting groove 131. Here, the inside is also relative to the edge as described above. The two ends of the second cross beam 140 can be formed with second tenon heads 141 inserted into the second mortise groove 133, so that the tenon-and-mortise connection can make the connection between the longitudinal beam 130 and the second cross beam 140 more stable.

[0050] In an embodiment, referring to Figure 4 , the limiting groove 131 and the second mortise groove 133 can be arranged at the end of the longitudinal beam 130, so that a longer longitudinal beam 130 is not needed, and the use of raw materials of the longitudinal beam 130 is saved. Of course, in other embodiments, the limiting groove 131 and the second mortise groove 133 can be arranged at a position close to the middle of the cross beam.

[0051] In an embodiment, referring to Figure 2 , Figure 4 , Figure 7 and Figure 8 , Figure 11 and Figure 12 , the suspension piece 200 can include a hanging piece 220 and a plug-in piece 230 connected to an end of the hanging piece 220 away from the beam frame 100. The hanging piece 220 and the plug-in piece 230 are arranged vertically, i.e., the hanging piece 220 is in a vertical state and the plug-in piece 230 is in a horizontal state during the working process. Of course, in other embodiments, the hanging piece 220 and the plug-in piece 230 can be arranged at an acute angle. An end of the plug-in piece 230 away from the hanging piece 220 can be provided with a strip-shaped protrusion 231, as shown in Figure 8 , the cross section of the strip-shaped protrusion 231 can be configured as a waist type. The slot hole 11 can include a first long slot hole 111 extending horizontally and a second long slot hole 112 communicating with the first long slot hole 111, referring to Figure 11 and Figure 12The second long hole 112 is formed from the outer wall of the battery box 10 inwardly, and the first long hole 111 extends inwardly from the side of the second long hole 112 away from the outer wall of the battery box 10, as shown in Figure 11 The cross section of the second long hole 112 can be configured as a waist-shaped hole shape, so that the strip-shaped protrusion 231 can be shape-fittingly inserted into the second long hole 112. In addition, the cross section of the first long hole 111 can be configured as a circular hole shape, and the hole diameter thereof can be configured to be not less than the maximum outer profile of the strip-shaped protrusion 231, so that after the strip-shaped protrusion 231 passes through the second long hole 112 into the first long hole 111, the strip-shaped protrusion 231 can be rotated to be arranged out of position with the hole opening of the second long hole 112 in the first long hole 111, so as to prevent it from being pulled out of the second long hole 112. In the embodiment of the present disclosure, the hole diameter of the first long hole 111 can be configured to match the maximum outer profile of the strip-shaped protrusion 231, so that after rotation, the strip-shaped protrusion 231 tightly abuts the inner wall of the first long hole 111, thereby providing a lifting force for the battery box 10. The user can manufacture a plurality of suspension pieces 200 according to the size of the slot hole 11 of different battery boxes 10 to meet the insertion requirements of the strip-shaped protrusion 231 to different slot holes 11.

[0052] The end of the hanging piece 220 close to the slot hole 11 can be provided with a through hole, and the insertion piece 230 can pass through the through hole, and the outer periphery of the insertion piece 230 is welded to the hole wall of the through hole.

[0053] In the embodiment, the second long hole 112 extends in the horizontal direction, so the strip-shaped protrusion 231 needs to pass through the second long hole 112 horizontally and then rotate 90 degrees to contact the top wall of the first long hole 111. Of course, in other embodiments, the second long hole 112 is arranged at an angle with the horizontal direction, and at this time, the strip-shaped protrusion 231 can contact the top wall of the first long hole 111 after passing through the second long hole 112 and rotating a small angle (less than 90 degrees).

[0054] In the embodiment, please refer to Figure 2 and Figure 3 The longitudinal beam 130, the hanging piece 220, the first transverse beam 120 and the second transverse beam 140 are all cut by a laser cutting machine from a steel plate. Therefore, the hanging piece 220 has a certain structural strength and rigidity, which ensures that external objects cannot directly impact the battery box 10, avoids the battery box 10 shell from being knocked and damaged, thereby avoiding causing damage to the battery cells in the battery box 10. The tenon and mortise structure is simple and has low cutting cost. After the tenon and mortise are connected, the stability of the beam frame 100 can be improved. After the longitudinal beam 130, the first transverse beam 120 and the second transverse beam 140 are connected by the tenon and mortise, the user can weld each connection point respectively to strengthen the stability of the connection.

[0055] Please refer to Figures 1 to 12The steps of using the lifting tool can include:

[0056] After the strip-shaped protrusion 231 passes through the second long slot hole 112 and reaches the first long slot hole 111, the suspension piece 200 is horizontally placed as shown in FIG. 6. Figure 9

[0057] The strip-shaped protrusion 231 is rotated by 90 degrees so that the strip-shaped protrusion 231 is in contact with the top wall of the first long slot hole 111, and the suspension piece 200 is vertically placed as shown in FIG. 7. Figure 10

[0058] The crane drives the beam frame 100 to the suspension piece 200, pushes the suspension piece 200 so that the end of the longitudinal beam 130 can pass through the insertion hole 210, until the end of the suspension piece 200 away from the slot hole 11 reaches the limiting slot 131, the crane slowly lifts the beam frame 100 upwards so that the end of the suspension piece 200 away from the slot hole 11 can be clamped with the limiting slot 131, and the state is as shown in FIG. 8, thereby completing the lifting process of the lifting tool on the battery box 10.
