[0042] Figure 1 It is a schematic diagram of the axial side structure of the battery-changing hanger provided in an embodiment of the utility model; Figure 2It is a schematic diagram of the axial structure of the battery swapping hoist provided by an embodiment of the utility model from another perspective (a schematic diagram of an unlocked state, i.e., a state where the battery swapping hoist is placed in or taken out of a battery box); Figure 3 It is a top view of the battery-exchanging hanger provided in an embodiment of the utility model.

[0043] See also Figure 1 , Figure 2 and Figure 3 According to a first aspect of an embodiment of the utility model, a battery swapping hanger is provided, which includes a supporting assembly 100, a locking hook assembly 200 and a driving assembly 300, wherein the locking hook assembly 200 includes a first locking hook 210 and a second locking hook 220, the first locking hook 210 is arranged on one side of the supporting assembly 100, and the second locking hook 220 is relatively arranged on the other side of the supporting assembly 100, the first locking hook 210 is rotatably connected to the supporting assembly 100, and the second locking hook 220 is also rotatably connected to the supporting assembly 100; the driving assembly 300 is arranged on the upper side of the supporting assembly 100, the driving assembly 300 is connected to the first locking hook 210, the first locking hook 210 can be rotated to a first preset position under the drive of the driving assembly 300, the driving assembly 300 is also connected to the second locking hook 220, and the second locking hook 220 can be rotated to a second preset position under the drive of the driving assembly 300.

[0044] Specifically, when it is necessary to transport battery boxes of different models, the first lock hook 210 can be rotated to a suitable position relative to the battery box to ensure that the first lock hook 210 can hook the crossbeam or longitudinal beam of the battery box. In this case, the position of the first lock hook 210 is the first preset position. It is easy to understand that different types of battery boxes correspond to different first preset positions. In other words, the first preset position needs to be pre-set according to different types of battery boxes.

[0045] The second preset position is set in a similar manner to the first preset position, and can be set with reference to the setting of the first preset position. It should be noted that the first preset position matches the second preset position. Specifically, after the second lock hook 220 reaches the second preset position, the first lock hook 210 and the second lock hook 220 need to hook the battery box evenly, for example, symmetrically distributed on both sides of the center of gravity of the battery box to ensure the stability of the battery box during transportation. The specific first preset position and the second preset position can be adaptively adjusted according to the actual situation of the battery box.

[0046] Figure 4 It is a structural schematic diagram of an A-type battery box provided by an embodiment of the utility model; Figure 5 It is a structural schematic diagram of a B-type battery box provided by an embodiment of the utility model; Figure 6 It is a schematic diagram of the structure of a C-type battery box provided by an embodiment of the utility model; Figure 7It is a structural diagram of a D-type battery box provided in an embodiment of the utility model. It should be noted that the aforementioned A, B, C, and D only refer to four different types and specifications of battery boxes provided in an embodiment of the utility model, and are not specific models of battery boxes.

[0047] See also Figures 4 to 7 The battery-changing lifting device provided in the embodiment of the utility model is a universal lifting device, which can be used to carry battery boxes of different models and specifications. Figures 4 to 7 This is a top view of several representative battery boxes given for explanation of the embodiments of the utility model. It can be easily seen that the positions of the cross beams or longitudinal beams on the upper sides of the several battery boxes for being hooked are different. For the existing lifting tools, since the position of the hooks is fixed, different types of battery boxes can only be designed with corresponding lifting tools. If the battery boxes to be transported front and back are of different models, the lifting tools need to be replaced, which makes the entire transportation process time-consuming and labor-intensive.

[0048] See also Figures 1 to 7 It can be understood that the battery swapping hanger provided in the embodiment of the utility model drives the first lock hook 210 to rotate to the first preset position through the drive assembly 300, and drives the second lock hook 220 to rotate to the second preset position through the drive assembly 300. In this way, when facing different types of battery boxes, it is only necessary to match and adjust the first preset position and the second preset position corresponding to the battery box to move the first lock hook 210 and the second lock hook 220 to a suitable position relative to the current battery box to be transported, so that the battery swapping hanger can meet the versatility of transporting battery boxes of different models. Compared with the prior art, the battery swapping hanger provided in the embodiment of the utility model changes the position of the first lock hook 210 and the second lock hook 220 by rotation, so that the battery swapping hanger can meet the needs of transporting different types of battery boxes, break the limitation of the one-to-one correspondence between the existing battery box and the battery swapping hanger, improve the transportation efficiency of the battery box, and save transportation costs.

[0049] Figure 8 It is a structural schematic diagram of the battery-exchanging hanger provided by an embodiment of the utility model in one state; Fig. 9 It is a structural schematic diagram of the battery-exchanging hanger provided by an embodiment of the utility model in another state; Fig.10 It is a structural schematic diagram of the battery-exchanging hanger provided in an embodiment of the utility model in another state.

[0050] See also Figures 1 to 3 as well as Figures 8 to 10In an optional embodiment of the present invention, the lock hook assembly 200 further includes a third lock hook 230 and a fourth lock hook 240. The first lock hook 210 and the third lock hook 230 are relatively arranged on one side of the support assembly 100, and the third lock hook 230 is rotatably connected to the support assembly 100. Correspondingly, the second lock hook 220 and the fourth lock hook 240 are relatively arranged on the other side of the support assembly 100, and the fourth lock hook 240 is also rotatably connected to the support assembly 100; the third lock hook 230 is connected to the driving assembly 300, and the third lock hook 230 can be rotated to the third preset position under the drive of the driving assembly 300; the fourth lock hook 240 is also connected to the driving assembly 300, and the fourth lock hook 240 can be rotated to the fourth preset position under the drive of the driving assembly 300. The setting method of the third preset position and the fourth preset position is similar to the setting method of the aforementioned first preset position. Specifically, the setting of the first preset position described above can be referred to. It can be understood that by providing four locking hooks, the contact points between the battery swapping hoist and the battery box can be increased, and the battery box can be more stable during transportation.

[0051] It should be noted that the first locking hook 210, the second locking hook 220, the third locking hook 230 and the fourth locking hook 240 can all perform 360° circumferential rotation along their own axes, and the specific rotation process and direction can be adaptively set according to actual conditions.

[0052] The following provides examples of the first preset position, the second preset position, the third preset position and the fourth preset position in the embodiment of the present invention relative to four different types of battery boxes: A, B, C and D.

[0053] See also Figure 2 , Figure 4 and Figure 8, taking the A-type battery box as an example, the A-type battery box is a sheet metal structure, the inner spacing between the two lifting beams is 1650mm, and there is no longitudinal beam. In the actual handling process, the first lock hook 210 can be rotated so that the lock tongue of the first lock hook 210 faces the direction a (first preset position) shown in the figure; the third lock hook 230 can be rotated so that the lock tongue of the third lock hook 230 faces the direction a (third preset position) shown in the figure; the second lock hook 220 can be rotated so that the lock tongue of the second lock hook 220 faces the direction b direction (second preset position); the fourth lock hook 240 can be rotated so that the lock tongue of the fourth lock hook 240 faces the b direction (fourth preset position) shown in the figure; taking type A battery box as an example, during use, the lock tongue rotates to the bottom of the corresponding lifting beam and is perpendicular to the lifting beam, which is the grasping state. The battery box can be lifted together with the battery swap hanger by the lifting device. In other words, each hook can hook the lifting beam from the inside to the outside of the lifting beam, thereby realizing the transportation of this type of battery box. When the battery box is transported to the target position, the battery swap hanger is lowered by the lifting device, and the two lock tongues on the same side are rotated to face each other, that is, Figure 2 The battery box is in the state shown in the figure (when it is parallel to the beam, the lock tongue is in the unlocked state at this time), and the battery swap hanger is raised to complete the transportation and placement of the battery box.

[0054] See also Figure 3 , Figure 5 and Fig. 9 Taking the B-type battery box as an example, the B-type battery box is a sheet metal structure, the outer spacing of the cross beam is 1250mm, and there is no longitudinal beam. During the actual transportation process, the first lock hook 210 can be rotated so that the lock tongue of the first lock hook 210 faces the direction b (first preset position) shown in the figure; the third lock hook 230 can be rotated so that the lock tongue of the third lock hook 230 faces the direction b (third preset position) shown in the figure; the second lock hook 220 can be rotated so that the lock tongue of the second lock hook 220 faces the direction a (second preset position) shown in the figure; the fourth lock hook 240 can be rotated so that the lock tongue of the fourth lock hook 240 faces the direction a (fourth preset position) shown in the figure. Based on this, each hook can hook the cross beam from the outside to the inside, thereby realizing the transportation of this type of battery box.

[0055] See also Figure 3 , Figure 6 and Fig. 9Taking the C-type battery box as an example, the C-type battery box is a frame structure, and the outer spacing between the two lifting beams is 1250mm. During the actual transportation process, the first lock hook 210 can be rotated so that the lock tongue of the first lock hook 210 faces the direction b (first preset position) shown in the figure; the third lock hook 230 can be rotated so that the lock tongue of the third lock hook 230 faces the direction b (third preset position) shown in the figure; the second lock hook 220 can be rotated so that the lock tongue of the second lock hook 220 faces the direction a (second preset position) shown in the figure; the fourth lock hook 240 can be rotated so that the lock tongue of the fourth lock hook 240 faces the direction a (fourth preset position) shown in the figure. Based on this, each hook can hook the beam from the outside to the inside of the beam, thereby realizing the transportation of this type of battery box.

[0056] See also Figure 3 , Figure 7 and Fig.10 Taking the D-type battery box as an example, the D-type battery box is a frame structure, the horizontal beam spacing is 850mm, the inner side spacing of the longitudinal beam is 720mm, and the lifting position is the longitudinal beam. During the actual transportation process, the first lock hook 210 can be rotated so that the lock tongue of the first lock hook 210 faces the d direction shown in the figure (the first preset position); the third lock hook 230 can be rotated so that the lock tongue of the third lock hook 230 faces the c direction shown in the figure (the third preset position); the second lock hook 220 can be rotated so that the lock tongue of the second lock hook 220 faces the d direction shown in the figure (the second preset position); the fourth lock hook 240 can be rotated so that the lock tongue of the fourth lock hook 240 faces the c direction shown in the figure (the fourth preset position). Based on this, each hook can hook the longitudinal beam from the inside to the outside of the longitudinal beam, thereby realizing the transportation of this type of battery box.

[0057] It should be noted that the above examples are only specific examples given for the convenience of explanation of the present invention and are not intended to be specific limitations of the embodiments of the present invention. Figures 4 to 7 Project on the same projection plane and make the centers of each figure coincide with each other. With this as a reference, the positions of the first lock hook 210, the second lock hook 220, the third lock hook 230 and the fourth lock hook 240 need to be set in the middle of the crossbeam of the A-type battery box and the crossbeam of the B-type battery box, and be set close to the longitudinal beam of the D-type battery box. The specific position can be adaptively set based on this reference to meet the transportation requirements of battery boxes of different types.

[0058] It should also be noted that, there are four locking hooks, each of which is arranged near the center of the inscribed circle of the beam to be grasped. Specifically, the distance between the first locking hook 210 and the second locking hook 220 needs to be set between 1.4m and 1.5m, that is, the distance between the third locking hook 230 and the fourth locking hook 240 also needs to be set between 1.4m and 1.5m; the distance between the first locking hook 210 and the third locking hook 230 needs to be set between 550mm and 600mm, that is, the distance between the second locking hook 220 and the fourth locking hook 240 also needs to be set between 550mm and 600mm; the setting range of the above spacing is a reference given in the embodiment of the utility model. It can be understood that by limiting the spacing between each locking hook within the above range, it can be ensured that the battery swap hoist can meet the handling requirements of various different models, avoiding the problem of incompatibility with various battery boxes due to inappropriate spacing between the locking hooks. The above value range and reference are only an example given in the utility model.

[0059] It should also be noted that when the battery swap hoist is for different models of battery boxes, or some types of battery boxes, the specific positions of the first hook, the second hook, the third hook and the fourth hook can be adaptively set according to the actual situation. It should also be noted that the spacing between the above-mentioned hooks can be complementary to the length of the lock tongue. For example, the spacing between the first lock hook 210 and the second lock hook 220 can be set slightly larger, and the lock tongues of the first lock hook 210 and the second lock hook 220 can be set longer accordingly to avoid the problem that the spacing between the first lock hook 210 and the second lock hook 220 is too large and the battery box cannot be hooked. Specifically, it can be adaptively adjusted, and the embodiments of the utility model will not be repeated here.

[0060] Fig.11 It is a side sectional view of the battery swap hanger provided in an embodiment of the utility model.

[0061] See also Figures 1 to 3 as well as Fig.11 In an optional embodiment of the utility model, four cylindrical bearing seats can be arranged on the support assembly 100, and the bearing seats can be fixed on the support assembly 100 by welding.

[0064] The rotating shaft 212 is rotatably connected in the bearing seat of the support assembly 100 through the upper bearing 215 and the lower bearing 216. The upper bearing 215 mainly bears the battery gravity load and the load eccentric bending moment. A bearing or bearing group that can withstand radial force and axial force at the same time can be used. This can not only withstand the load of lifting the battery box, but also withstand the reverse load during guiding; the lower bearing 216 mainly bears the eccentric bending moment. A bearing that only withstands radial force or a bearing used in pair with the upper bearing 215 can be used.

[0065] The drive seat 214 is mounted on the top of the bearing seat of the support assembly 100. A mounting plate for mounting the induction switch is provided on the drive seat 214. The central positioning hole of the induction plate 213 is mounted on the rotating shaft 212.

It should be noted that the bearing locking thread section is only required when the lower bearing 216 and the upper bearing 215 are tapered roller bearings or angular contact ball bearings arranged in pairs.

[0067] Fig.13 This is the second schematic diagram of partial details of the lock hook provided in the embodiment of the utility model.

[0068] See also Fig.13 The lock hook 211 is mainly composed of a supporting part and a connecting part. The connecting part is used to connect with the rotating shaft 212.
