[0015] The present application will be further described in detail by the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become more apparent.

[0016] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. Unless specifically indicated otherwise, the drawings are not necessarily to scale.

[0017] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0018] For the convenience of understanding the battery carrier provided by the embodiment of the present application, the application scenario of the battery carrier is first described. The battery carrier provided by the embodiment of the present application is used for assembling batteries into a battery pack. When the batteries are assembled into a pack, the batteries need to be arranged in a row. Referring to Figure 1 , the battery 100 is in a long strip structure, and the main structure of the battery 100 includes a shell and a battery cell in the shell. The shell has a flange in the width and length directions, and the pole of the battery is arranged on the surface of the shell in the thickness direction. For Figure 1 , there is no suitable battery carrier for assembling the battery 100 into a pack. Therefore, the embodiment of the present application provides a battery carrier to facilitate the positioning and assembly of the battery. The specific drawings and embodiments will be described in detail below.

[0019] For the convenience of understanding the battery carrier provided by the embodiment of the present application, the long side wall 102 and the short side wall 101 of the battery 100 are defined. The long side wall 102 of the battery 100 is the side wall with a larger size among the side walls of the battery 100, and the short side wall 101 of the battery 100 is the side wall with a smaller size among the side walls of the battery 100. In the embodiment of the present application, the short side wall 101 of the battery 100 is also referred to as the end of the battery 100. When the battery 100 is assembled into a pack, the large side surface of the battery (the surface with the largest area in the battery) is arranged oppositely, and the adhesive 200 is arranged on the large side surface, and the batteries 100 are fixed by the adhesive 200.

[0020] In the embodiments of the present application, the thickness of the shell of the battery 100 is between 0.2-0.4mm, and the thickness of the shell is 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, etc. The length of the shell is more than 60mm, such as 600mm, 610mm, 620mm, 650mm, 700mm, etc. The material of the shell is aluminum material, and when the above-mentioned size is used, deformation is easy to occur. Therefore, the traditional direct stacking by the push plate will cause the battery to deform, and the busbar of the battery pack is welded from the side, so the distance between the adjacent batteries needs to be guaranteed, and therefore accurate distance setting and more accurate in-situ holding are required to avoid deformation and displacement of the battery during stacking.

[0021] Reference Figure 2 and Figure 3 , Figure 2 a side view of a battery carrier provided by the embodiments of the present application is shown, Figure 3 a schematic view of the overall structure of the battery carrier is shown. The main structure of the battery carrier includes a carrier 10 and a functional assembly for grouping batteries arranged on the carrier 10. When assembled, the functional assembly is used to carry the batteries and stack the carried batteries into groups through the carrier 10. In addition, in the embodiments of the present application, a support table 20 can also be included, which serves as a support structure to support the above-mentioned carrier 10. It should be understood that 30 can be an optional structure in the embodiments of the present application. The structure of the battery carrier will be described one by one as follows.

[0022] Reference Figure 4 , Figure 4 a schematic view of the structure of the carrier is shown. The carrier 10 provided by the embodiments of the present application is a cuboid frame structure, which serves as a support structure to carry the functional assembly of the battery carrier. Illustratively, the carrier 10 can include two horizontal frames arranged in parallel along the height direction, which are named as a first horizontal frame 11 and a second horizontal frame 12 for convenience of description. In addition, a vertical frame 13 is used to connect the two horizontal frames. The horizontal frame is fixedly connected with the vertical frame 13 to form a cuboid structure.

[0023] The first horizontal frame 11 includes two first frames and two second frames arranged oppositely, and the first frame and the second frame are fixedly connected to form a rectangular structure. The first horizontal frame 11 and the second horizontal frame 12 are both used to support the functional assembly.

[0024] For convenience of description, an XYZ coordinate system is constructed, in which the O point is located at one vertex of the carrier 10, the X direction is along the length direction of the first frame, the Y direction is along the length direction of the second frame, and the Z direction is parallel to the vertical frame of the carrier 10.

[0025] It should be understood that the carrier provided in the embodiments of the present application is not limited to the cuboid frame structure as the above examples, and other structural forms can also be adopted, which will not be described in detail herein.

[0026] With reference to Figure 4 , Figure 5 and Figure 6 , Figure 5 a partial enlarged view at A in the present application Figure 4 is shown, Figure 6 a schematic view of the cooperation between the carrier and the side clamping mechanism provided in the embodiments of the present application is shown. It should be understood that in Figure 6 for the convenience of showing the structure of the carrier, the second horizontal frame and the vertical frame in the carrier are removed, and only the first horizontal frame is reserved.

[0027] The functional assembly provided in the embodiments of the present application can include components with different functions. For example, the functional assembly can include components such as the bearing seat 14, the locking mechanism 16, and the unlocking mechanism 18. The bearing seat 14 is used to bear the battery, the locking mechanism 16 is used to lock the battery, and the unlocking mechanism 18 is used to unlock the bearing seat 14. Through the cooperation of the bearing seat 14, the locking mechanism 16, and the unlocking mechanism 18, the battery stack is realized.

[0028] In the embodiments of the present application, the number of the bearing seats 14 is multiple, and the number of the bearing seats 14 is not less than the number of the battery stack. For example, the number of the bearing seats 14 is M, and the number of the batteries is N, wherein M≥3, N≥3, and M≥N, and M and N are positive integers. It should be understood that in Figure 6 for the convenience of understanding, only part of the bearing seats 14 is shown.

[0029] The plurality of bearing seats 14 are arranged along a first direction, and the first direction is the direction of the battery stack. In the constructed coordinate system, the first direction can be the X direction or the Y direction. When the first direction is different, only the difference in the stacking direction is different, and other stacking modes are the same, so in the embodiments of the present application, the first direction is taken as the X direction as an example.

[0030] Each bearing seat 14 is in sliding connection with the carrier 10 and can slide along the first direction. When the direction of the battery stack is along the X direction, the length direction of the bearing seat 14 is along the Y direction. The two ends of the bearing seat 14 are in sliding connection with the two first frame bodies of the first horizontal frame, respectively. Specifically, when slidingly connecting, a slide rail can be arranged on the first frame body, and the bearing seat 14 is provided with a slide groove matched with the slide rail. Alternatively, a slide groove can be arranged on the first frame body, and the bearing seat 14 is provided with a slide rail matched with the slide groove. Regardless of which way is adopted, the sliding connection can be realized through the cooperation of the slide rail and the slide groove. Of course, in addition to the above example of the sliding connection mode, other sliding connection modes can also be adopted to realize the sliding connection between the bearing seat 14 and the carrier 10.

[0031] When the battery is carried, the carrier 14 is provided with a receiving groove for carrying the battery, the length direction of the receiving groove is along the second direction, and the receiving groove can pass through the carrier 14. When assembled, the battery can be placed in the receiving groove and limited by the side wall of the receiving groove. As an optional solution, when the carrier 14 carries the battery, the long side wall of the carrier 14 carries the battery, thereby improving the stability of the carrier 14 when carrying the battery.

[0032] For the convenience of description, a first end and a second end of the carrier 10 are defined, wherein the first end and the second end are two ends of the carrier 10 along the first direction.

[0033] Before the battery is stacked, a plurality of carriers 14 are close to the first end of the carrier 10, and the plurality of carriers 14 are arranged along the first direction.

[0034] Referring to Figure 3 When the battery is placed into the outermost carrier 14 by the external clamping mechanism, the battery and the carrier 14 are pushed to slide along the first direction by the driving mechanism 19 and moved to the second end of the carrier 10. After the battery and the carrier 14 are moved to the second end of the carrier 10, the adjacent batteries are fixed by the adhesive. The driving mechanism 19 is reset, and the clamping mechanism places the battery into the outermost carrier 14 again. The battery is pushed in the above-mentioned manner one by one until the battery is stacked.

[0035] The above-mentioned clamping mechanism can be a common mechanism for moving the battery, such as a mechanical arm or a robot. The driving mechanism 19 is a reciprocating linear driving mechanism, such as a driving cylinder, a driving hydraulic cylinder or a linear motor. When arranged, the driving mechanism 19 is located at the first end of the carrier 10. The driving mechanism 19 presses the battery and pushes the battery to drive the carrier 14 to slide along the first direction to the second end. The driving mechanism 19 that presses one end of the battery can be provided with a push plate.

[0036] From Figure 3 As can be seen, the driving mechanism 19 is inserted between the adjacent carriers 14 from below the carrier 10, so that when the driving mechanism 19 is arranged, the driving mechanism 19 can be correspondingly arranged with a lifting mechanism to drive the driving mechanism 19 to lift along the Z direction. Illustratively, the lifting mechanism is connected with the support table 20, and the driving mechanism 19 is connected with the lifting mechanism. In use, the lifting mechanism is lowered, and the push plate of the driving mechanism 19 is withdrawn from the gap between the carriers 14, and when the lifting mechanism is raised, the push plate of the driving mechanism 19 can be inserted into the gap between the carriers 14.

[0037] In use, when the telescopic part is extended to the lower side of the carrier seat 14 to be pushed, the lifting mechanism is raised, the push plate connected by the driving mechanism 19 is located at one side of the carrier seat 14, the driving mechanism 19 is extended, and the carrier seat 14 is pushed to move. After the battery stack is placed in place, the lifting mechanism is lowered, and the driving mechanism 19 is retracted. The above process is repeated to sequentially complete the stacking of the battery. It should be understood that the lifting mechanism described above can be a common mechanism that can realize lifting, such as a driving cylinder or a driving hydraulic cylinder.

[0038] With reference to the foregoing Figure 5 As an optional solution, the battery carrier provided by the embodiment of the present application can further include a limiting member 15 arranged between any two adjacent carrier seats 14 and used for limiting the spacing between the carrier seats 14. The limiting member 15 is used to limit the spacing between the carrier seats 14 when the carrier seats 14 are not carrying batteries. As an example, the limiting member 15 includes a limiting rod 151 and an elastic member 152 arranged on the limiting rod 151. The two ends of the limiting rod 151 are provided with shoulders, and the shoulders are used to limit the maximum spacing between the carrier seats 14.

[0039] For example, the limiting rod 151 is arranged between two adjacent carrier seats 14, and the carrier seats 14 are provided with through holes matched with the limiting rod 151. The diameter of the through holes is greater than the diameter of the limiting rod 151 and less than the diameter of the shoulder. The shoulders at the two ends of the limiting rod 151 are used to abut against the opposite sides of the two adjacent carrier seats 14, respectively, and the two ends of the elastic member 152 are used to abut against the two carrier seats 14, respectively. Under the elastic force of the elastic member 152, the two adjacent carrier seats 14 are pushed to slide away from each other and abut against the corresponding shoulders, so as to limit the spacing between the two carrier seats 14 by the two shoulders. It should be understood that the elastic member 152 provided by the embodiment of the present application can be a compression spring or a rubber sleeve with elastic properties.

[0040] When the plurality of carrier seats 14 are connected in series by the limiting rod 151, only one limiting rod 151 is arranged in the carrier seat 14 at the end, and the remaining carrier seats 14 are arranged with two limiting rods 151. When the carrier seat 14 is arranged with two limiting rods 151, the two limiting rods 151 are arranged staggered. Thus, each carrier seat 14 can be pushed away by the elastic member 152, so that the carrier seats 14 without carrying batteries can form a stable spacing.

[0041] As a deformable solution, the limiting member 15 of the present application can also be an elastic column, such as an elastic rubber column or an elastic silica gel column. The two ends of the elastic rubber column are fixedly connected with two adjacent carrier seats 14, respectively. When the carrier seats 14 are not carrying batteries, the two carrier seats 14 can be pushed away by the elastic deformation of the elastic rubber column.

[0042] It should be understood that when the spacing between the bearing seats 14 is limited by the limiting members 15, sufficient space should be reserved between the bearing seats 14 to ensure that the batteries can be placed. For example, the length of the limiting rod 151 is greater than the thickness of one battery and less than the thickness of two batteries.

[0043] With reference to Figure 6 、 Figure 7 and Figure 8 , Figure 7 A cooperation schematic diagram of the locking mechanism and the bearing seat provided in the embodiment of the application is shown, Figure 8 A structural schematic diagram of the locking mechanism is shown. When the bearing seat 14 carrying the batteries moves to the second end of the carrier 10, the batteries need to be locked and fixed. Therefore, the battery carrier provided in the embodiment of the application further comprises a locking mechanism 16, which is used to lock the bearing seat 14 to ensure the stability of the stacked batteries.

[0044] To ensure that the batteries can maintain a stable stacking state when stacked at the second end of the carrier 10, the battery carrier provided in the embodiment of the application further comprises a locking mechanism 16, which is used to lock the bearing seat 14. For example, when the bearing seat 14 moves to the second end of the carrier 10, that is, when the batteries are stacked, to ensure that the batteries can be stacked stably, the bearing seat 14 is locked and fixed by the locking mechanism 16, so that the batteries can maintain a stable state after being stacked.

[0045] The locking mechanism 16 corresponds to the bearing seat 14. For example, each bearing seat 14 corresponds to two locking mechanisms 16, and the two locking mechanisms 16 are arranged on the outside of the two ends of the corresponding bearing seat 14. Among them, the two ends of the bearing seat 14 refer to the two end portions in the length direction along the second direction. In the embodiment of the application, the locking mechanism 16 is arranged at both ends of the bearing seat 14 to ensure the stability of the stacked batteries.

[0046] Taking the locking mechanism 16 on one side as an example, the number of the locking mechanisms 16 is multiple and matches the number of the bearing seats 14. The multiple locking mechanisms 16 are arranged close to the second end of the carrier 10, and the arrangement direction is along the first direction. When the bearing seat 14 moves from the first end to the second end of the carrier 10, the locking mechanisms 16 are sequentially locked to the bearing seats 14 in the order of arrangement. When the subsequent bearing seats 14 move to the second end of the carrier 10, the locking mechanisms 16 are sequentially locked to the bearing seats 14 to ensure that the position of each bearing seat 14 is fixed, thereby ensuring the stability of all the batteries.

[0047] It should be understood that when the locking mechanism 16 is arranged, the adjacent locking mechanisms 16 define the spacing between the batteries, and therefore when the locking mechanism 16 is arranged, it should be ensured that the batteries are not excessively squeezed, and it should be ensured that the batteries can be fixed by the adhesive.

[0048] The specific structure of the locking mechanism 16 can include a base 161, a plug rod 162, and a first lever 163. The base 161 is a support structure for carrying the plug rod 162 and the first lever 163; the plug rod 162 is a functional component of the locking mechanism 16 for locking the carrier seat 14; and the first lever 163 is a driving mechanism for pushing the plug rod 162 out of the base 161 to lock, so that the plug rod 162 can lock the carrier seat 14.

[0049] In an implementable scheme, the overall structure of the base 161 is a U-shaped structure, and the opening direction of the U-shaped structure is away from the carrier 10. For the convenience of description, several side walls of the base 161 are defined, and the side walls of the base 161 include a horizontal side wall and two vertical side walls; wherein the horizontal side wall is toward the carrier 10, the two vertical side walls are arranged along the first direction, and the length direction of each vertical side wall is parallel to the second direction.

[0050] The plug rod 162 is a functional component of the locking mechanism 16, which is used to lock the carrier seat 14. In a specific arrangement, the plug rod 162 is slidingly assembled on the base 161. For example, the horizontal side wall of the base 161 is provided with a through hole extending along the second direction, and the plug rod 162 is arranged in the through hole and can move along the second direction relative to the base 161. The length direction of the plug rod 162 is along the second direction, the first end of the plug rod 162 is located in the base 161, and the second end of the plug rod 162 is located outside the base 161. The first end of the plug rod 162 is used to cooperate with the first lever 163, and the second end of the plug rod 162 is used to abut against the carrier seat 14. When it is necessary to lock the carrier seat 14, the plug rod 162 slides out of the base 161, and the second end of the plug rod 162 abuts against the carrier seat 14 to achieve the locking of the carrier seat 14.

[0051] When the plug rod 162 abuts against the carrier seat 14, the second end of the plug rod 162 abuts against one side of the second end of the carrier seat 14 away from the carrier 10, so as to provide a supporting force for abutting the carrier seat 14 against the second end of the carrier 10 by the plug rod 162.

[0052] As an optional solution, the end of each carrier 14 is provided with a notch which is engaged with the insertion rod 162 of the corresponding locking mechanism 16. When the locking mechanism 16 locks the carrier 14, the insertion rod 162 is inserted into the notch to lock and fix the carrier 14. For example, the end of the carrier 14 is provided with a notch on the side away from the second end of the carrier 10, so as to form a stepped structure on the side of the carrier 14 away from the second end of the carrier 10. When the insertion rod 162 is in abutting engagement with the carrier 14, the insertion rod 162 abuts against the stepped surface of the stepped structure to abut the carrier 14 against the second end of the carrier 10. As a specific implementation, the stepped surface of the stepped structure which is used to engage with the insertion rod 162 is provided with a chamfer, so as to facilitate the insertion of the insertion rod 162 into the notch in the second direction.

[0053] The first lever 163 is in the shape of a rod, and is rotatably connected with the base 161 when connected with the base 161. For example, the first lever 163 is rotatably connected with the base 161 through a rotating shaft, and the length direction of the rotating shaft is parallel to the first direction, i.e., the first lever 163 rotates around an axis which is parallel to the first direction. The rotating shaft is located between the two ends of the length direction of the first lever 163. The first end of the first lever 163 is exposed outside the base 161 and serves as an operation end for driving the first lever 163. The second end of the first lever 163 is located inside the base 161 and serves as a driving end for driving the first end of the insertion rod 162. When the first lever 163 rotates around the axis, the second end of the first lever 163 can be used to push the insertion rod 162 out of the base 161, like a lever. When the rotating shaft is specifically arranged, the rotating shaft is close to the second end of the first lever 163, so that the first lever 163 can be rotated by a smaller force.

[0054] When the base 161 adopts the above-mentioned U-shaped structure, the first lever 163 is located between the two vertical side walls, and the two vertical side walls are respectively provided with a through hole which is engaged with the rotating shaft of the first lever 163. The rotating shaft is respectively arranged in the two through holes and supports the first lever 163. When the first lever 163 rotates relative to the base 161, the first lever 163 can be fixedly connected with the rotating shaft, and the rotating shaft is rotatably connected with the vertical side wall; or the first lever 163 can be rotatably connected with the rotating shaft, and the rotating shaft is fixedly connected with the vertical side wall.

[0055] When the first lever 163 is engaged with the insertion rod 162, the locking mechanism 16 further comprises a connecting rod 164, one end of the connecting rod 164 is rotatably connected with the second end of the first lever 163, and the other end of the connecting rod 164 is rotatably connected with the first end of the insertion rod 162, so as to form a crank slider mechanism; wherein the first lever 163 serves as a crank, and the insertion rod 162 can be equivalent to a slider.

[0056] When the first lever 163 rotates relative to the base 161, the insertion lever 162 can be pushed or pulled to slide relative to the base 161. For example, when the carrier seat 14 needs to be locked, the first lever 163 is counterclockwise rotated to push the insertion lever 162 to slide out of the base 161 and press against the end of the carrier seat 14; when the carrier seat 14 needs to be unlocked, the first lever 163 is clockwise rotated to pull the insertion lever 162 to slide into the base 161 to unlock the carrier seat 14. Of course, the insertion lever 162 can be pulled to slide into the base 161 when the first lever 163 is counterclockwise rotated, and the insertion lever 162 can be pushed to slide out of the base 161 when the first lever 163 is clockwise rotated.

[0057] When the insertion lever 162 is locked, the force between the insertion lever 162 and the carrier seat 14 is along the first direction when the insertion lever 162 locks the carrier seat 14, and the sliding direction of the insertion lever 162 is along the second direction, so that the force between the insertion lever 162 and the carrier seat 14 does not push the insertion lever 162 to slide when the insertion lever 162 presses against the carrier seat 14, and the insertion lever 162 can be kept at the position.

[0058] Referring to Figure 9 After the batteries are grouped, the carrier seat 14 needs to be unlocked so that the carrier seat 14 can be moved from the second end of the carrier 10 to the first end of the carrier 10. Therefore, the battery carrier provided by the embodiments of the present application further comprises an unlocking mechanism 18 for synchronously unlocking the carrier seat 14 locked by each locking mechanism 16. When the unlocking mechanism 18 is specifically arranged, the unlocking mechanism 18 can correspond to the locking mechanism 16.

[0059] When the locking mechanism 16 is arranged on both sides of the carrier seat 14, the unlocking mechanism 18 is correspondingly arranged on both sides of the carrier 10, and the two unlocking mechanisms 18 are symmetrically arranged, so that the unlocking mechanism 18 on one side is taken as an example for description.

[0060] In a specific embodiment, the unlocking mechanism 18 comprises a support plate 181 for carrying the locking mechanism 16 on the same side of the carrier 10. The support plate 181 is a long strip-shaped plate structure, and the length direction of the support plate 181 is along the first direction. When the locking mechanism 16 is specifically carried, the plurality of locking mechanisms 16 are arranged at intervals along the length direction of the support plate 181.

[0061] The support plate 181 is arranged in sliding connection with the carrier 10 and can slide along the second direction. For example, the first horizontal frame 11 of the carrier 10 is provided with a sliding rail, the length direction of the sliding rail is along the second direction, the support plate 181 is slidingly assembled on the sliding rail and can slide back and forth along the second direction, as shown by the direction of the double-headed arrow in Figure 9 .

[0062] The unlocking mechanism 18 further comprises an unlocking assembly 182 for driving the support plate 181 to slide and lock at a first set position. For example, as shown in the left side of the locking mechanism 18 in Figure 9 When the unlocking assembly 182 drives the support plate 181 to lock at the first set position, the locking mechanism 16 can lock the carrier 14. That is, when the unlocking assembly 182 drives the support plate 181 to lock at the first set position, the insertion rod 162 of the locking mechanism 16 can lock the carrier 14 under the driving of the first lever 163. For example, as shown in the right side of the locking mechanism 18 in Figure 9 When the unlocking assembly 182 drives the support plate 181 to move to the second set position, the locking mechanism 16 can unlock the carrier 14. That is, when the support plate 181 is at the second set position, even if the first lever 163 drives the insertion rod 162 to slide out of the base 161 to the outermost end, the insertion rod 162 cannot lock the carrier 14. Here, the first set position is closer to the carrier 10 than the second set position. And when the insertion rod 162 locks the carrier 14 in the second direction, the overlapping distance of the insertion rod 162 and the carrier 14 is less than the distance between the first set position and the second set position.

[0063] Referring to Figure 8 and Figure 9 For the convenience of understanding the unlocking assembly 182 provided in the embodiments of the present application, the cooperation between the locking mechanism 16 and the unlocking mechanism 18 is introduced as follows. Before the batteries are stacked, the unlocking assembly 182 drives the support plate 181 to slide to the first set position close to the carrier 10, at which time the locking mechanism 16 can be at the working position, that is, the position at which the locking mechanism 16 can lock the carrier 14. After the driving mechanism 19 drives the carrier 14 with the batteries to move to the second end of the carrier 10, the first lever 163 of the locking mechanism 16 drives the insertion rod 162 to be exposed and abut against the carrier 14 to complete the locking of the carrier 14. The driving mechanism 19 retreats and drives the next carrier 14 with the batteries, and the corresponding locking mechanism 16 locks the carrier 14. The above-mentioned operations are repeated to sequentially lock all the carriers 10 with the batteries. When all the batteries are stacked and adhesively fixed, the stacked battery pack is removed. Or after the batteries are adhesively fixed, the batteries are removed. Before the removal, the unlocking assembly 182 drives the support plate 181 to slide to the second set position away from the carrier 10, at which time, although the insertion rod 162 is still at the maximum exposed position, the movement of the support plate 181 can make the locking mechanism 16 unlock the carrier 14.

[0064] As an example, the unlocking assembly 182 provided by the embodiments of the present application can include a driving member 1821 and a connecting rod 1822. In assembly, the driving member 1821 is rotationally connected with the carrier 10, one end of the connecting rod 1822 is hingedly connected with the driving member 1821, and the other end is hingedly connected with a fixing block 1811 provided on the support plate 181; wherein the other end of the connecting rod 1822 refers to the end of the connecting rod 1822 away from the driving member 1821.

[0065] In the present application, the unlocking assembly 182 constitutes a connecting rod assembly, and the rotation of the driving member 1821 is converted into the sliding of the support plate 181 through the connecting rod assembly. Alternatively, the driving member 1821, the connecting rod 1822 and the support plate 181 can also be regarded as a crank slider assembly. In this case, the driving member 1821 serves as a crank, and the support plate 181 serves as a slider.

[0066] The driving member 1821 is specifically a horizontally arranged L-shaped rod structure. The horizontal end of the driving member 1821 is hingedly connected with the first horizontal frame 11. Illustratively, the first horizontal frame 11 is provided with a notch for accommodating the driving member 1821 and the connecting rod 1822, which is located below the support plate 181.

[0067] For the convenience of connecting the unlocking assembly 182 provided by the embodiments of the present application, the working principle of the unlocking assembly 182 is described in combination with the structure of the unlocking assembly 182.

[0068] When the driving member 1821 is rotated to the third set position relative to the carrier 10, the driving member 1821 is locked relative to the carrier 10, and the connecting rod 1822 drives the support plate 181 to slide to the first set position and lock. Specifically, in the process of rotation, the driving member 1821 drives the connecting rod 1822 to move towards the carrier 10, thereby driving the support plate 181 to slide to the first set position and lock. The locking of the support plate 181 is achieved by locking the driving member 1821 relative to the carrier 10.

[0069] When the driving member 1821 is rotated to the fourth set position relative to the carrier 10, the connecting rod 1822 drives the support plate 181 to slide to the second set position. That is, the driving member 1821 is rotated counterclockwise, and in the process of rotation, the connecting rod 1822 is driven to move away from the carrier 10, thereby driving the support plate 181 to slide away from the carrier 10 to the second set position. As described above, the locking mechanism 16 will release the locking of the carrier seat 14 even when it is in the locked state (the insertion rod 162 is exposed) at this position.

[0070] As an optional solution, the unlocking mechanism 18 provided by the embodiment of the present application further comprises a second lever 40, which is used to cooperate with the locking mechanism 16 to release the locking of the insertion rod 162 by the first lever 163 when the support plate 181 slides. For example, the second lever 40 is fixed relative to the carrier 10. The second lever 40 is used to drive the first lever 163 to reset the insertion rod 162 when each support plate 181 slides to the second setting position. As shown in the cooperation of the right locking mechanism and unlocking mechanism in FIG. 8B. Figure 9 The second lever 40 is fixedly connected with the carrier 10. During the sliding of the locking mechanism following the support plate 181, the second lever 40 can push the first lever 163 to reset.

[0071] For example, the length direction of the second lever 40 is along the first direction, and in the second direction between the first setting position and the second setting position, and the setting height (Z direction) of the second lever 40 is lower than the height of the first lever 163. During the movement of the support plate 181 from the first setting position to the second setting position, the first lever 163 moves away from the carrier 10 following the support plate 181, and when it moves to the position of the second lever 40, the second lever 40 is in contact with the first lever 163, and during the continuous movement of the first lever 163, the second lever 40 drives the first lever 163 to rotate clockwise, thereby pulling the insertion rod 162 to reset through the first lever 163. The reset position of the insertion rod 162 is the position where the insertion rod 162 is not locked to the carrier seat 14 when the support plate 181 is in the first setting position.

[0072] As can be seen from the above description, the battery carrier provided by the embodiment of the present application fixes each carrier seat carrying the battery through the locking mechanism, so that the battery can be kept stable after stacking, improves the effect of stacking the battery, and improves the safety of the battery. In addition, the unlocking mechanism releases the locking state of the locking mechanism, which facilitates the disassembly of the battery.

[0073] Reference Figure 3 As an optional solution, the battery carrier provided by the embodiment of the present application further comprises a top pressing plate 17, which is used to cooperate with the carrier seat 14 to press against the other side wall of the battery relative to the carrier seat 14. For example, the number of top pressing plates is multiple, and the number of top pressing plates 17 can correspond to the number of carrier seats 14.

[0074] The plurality of top pressing plates 17 are located on one side of the second end of the carrier 10 and are arranged along the first direction. The arrangement interval corresponds to the interval when the carrier seat 14 is fixed, so that each carrier seat 14 corresponding to the top pressing plate 17 can press and fix the side wall of the battery when the battery is stacked in place.

[0075] The support beam is arranged on the second horizontal frame, the top pressing plate is parallel to the support beam and is movable along the Z direction relative to the support beam. Exemplarily, the top pressing plate 17 is connected with the support beam through elastic members, and the top pressing plate is pushed to move downward through the elastic members; or the top pressing plate is connected with the support plate through bolts or screws, and the top pressing plate is pushed to move downward by rotating the bolts or screws. Alternatively, the top pressing plate 17 can be driven to move downward through other manners.

[0076] When the battery is clamped, first, the driving mechanism 19 moves the carrier seat 14 and the battery to the second end of the carrier 10, and after the carrier seat 14 is moved to the position, the carrier seat 14 is locked through the locking mechanism. The top pressing plate 17 is pressed downward to clamp and fix the battery.

[0077] As can be seen from the above description, after the battery is stacked, the two opposite long side walls of the battery are fixed through the cooperation of the top pressing plate 17 and the carrier seat 14, thereby improving the stability of the battery during stacking. The top pressing plate 17 can be pressed tightly by screwing.

[0078] As an optional solution, one side of the top pressing plate 17 facing the battery is provided with a clamping groove corresponding to the side wall of the battery. When the top pressing plate 17 is pressed against the battery, the clamping groove is clamped on the side wall of the battery, thereby improving the stability of the battery.
