[0052] At present, in battery swap stations, battery swap devices such as RGV (Rail Guided Vehicle) carts are usually used to carry batteries to the bottom of the vehicle, and the top of the battery is fixed to the bottom of the vehicle with a lock. Since the frame that fixes the battery is located at the bottom of the vehicle, if the load on the vehicle is uneven, the bottom battery frame will tilt. If the posture tilts too much, the battery will fail to lock, causing the battery swap to be interrupted, and reducing the battery swap efficiency of the battery swap station.

[0053] In order to solve the above technical problems, an embodiment of the present application provides a battery swap device, which includes a base plate and a support mechanism. The support mechanism is arranged on the base plate, and the support mechanism includes a driving member, a limiting member, an elastic member and a support member.

In the above scheme, if the battery swap device cannot lock the battery to the vehicle during battery swap, it means that the frame of the vehicle is tilted and deformed, and the limiting member can be driven to move by the driving member of the support mechanism to lift the support member, and the elastic member cannot be compressed. The battery is lifted up at this position of the support member, which is conducive to adapting to the deformed vehicle frame, so that the battery can be successfully locked on the vehicle, thereby improving the battery swap efficiency of the battery swap station.

[0054] The embodiment of the present application provides an electric device using a battery as a power source, and the electric device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0055] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0058] Please refer to Figure 2 , Figure 2An exploded view of a battery provided for some embodiments of the present application. The battery 100 includes a battery box and a battery cell 20. In some embodiments, the battery box may include an upper cover 10 and a box body 30, the upper cover 10 and the box body 30 cover each other, and the upper cover 10 and the box body 30 jointly define a receiving cavity for accommodating the battery cell 20. The box body 30 may be a hollow structure with one end open, and the upper cover 10 may be a plate-like structure, and the upper cover 10 covers the open side of the box body 30, so that the upper cover 10 and the box body 30 jointly define a receiving cavity; the upper cover 10 and the box body 30 may also be hollow structures with one side open, and the open side of the upper cover 10 covers the open side of the box body 30. Of course, the battery box formed by the upper cover 10 and the box body 30 may be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0059] like Figure 3 As shown, Figure 3 A schematic diagram of a partial structure of a battery provided for some embodiments of the present application. In the battery 100, there may be a plurality of battery cells 20, and the plurality of battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the plurality of battery cells 20 are both connected in series and in parallel.

[0061] Figure 4 A schematic diagram of the structure of a battery replacement device provided in some embodiments of the present application; Figure 5 A schematic diagram of the structure of a support mechanism provided in some embodiments of the present application.

[0062] Please refer to Figure 4 and Figure 5In the first aspect, an embodiment of the present application provides a battery exchange device 400, which includes a base plate 50 and a support mechanism 60. The support mechanism 60 is arranged on the base plate 50, and the support mechanism 60 includes a driving member 61, a limiting member 62, an elastic member 63 and a support member 64. The driving member 61 is connected to the limiting member 62, and is used to drive the limiting member 62 to move so that the limiting member 62 supports the support member 64 or stays away from the support member 64; the elastic member 63 is arranged on the side of the support member 64 close to the base plate 50, and the support member 64 is used to support the battery 100.

[0063] The battery exchange device 400 may be an RGV vehicle, or may also be an AGV (Automated Guided Vehicle) vehicle.

[0064] The battery 100 is placed on the bottom plate 50 of the vehicle 1000, and the support mechanism 60 supports the battery 100. The elastic member 63 may be a spring, rubber or other elastic member. Since the support mechanism 60 has the elastic member 63, when the battery 100 is lifted up and installed on the frame of the vehicle 1000, the elastic member 63 is compressed, which has a buffering effect and reduces the risk of damage to the battery 100.

[0065] The driving member 61 of the support mechanism 60 may include a motor, a cylinder or a hydraulic cylinder, etc. The driving member 61 may drive the limiting member 62 to move in the horizontal direction, so that the limiting member 62 can move horizontally to the bottom of the support member 64. Alternatively, the driving member 61 may also drive the limiting member 62 to move in the vertical direction, so that the limiting member 62 moves upward to contact the bottom of the support member 64.

[0066] In the above scheme, if the battery exchange device 400 cannot lock the battery 100 to the vehicle 1000 during battery exchange, it means that the frame of the vehicle 1000 is deformed, and the driving member 61 of the support mechanism 60 can drive the limiting member 62 to move, so as to lift the support member 64, and the elastic member 63 cannot be compressed. The battery 100 is lifted up at this position of the support member 64, which is conducive to adapting to the deformed frame of the vehicle 1000, so that the battery 100 can be successfully locked on the vehicle 1000, thereby improving the battery exchange efficiency of the battery exchange station.

[0067] In some embodiments, there are multiple supporting mechanisms 60 , and the multiple supporting mechanisms 60 are respectively located at different positions of the bottom plate 50 .

[0068] The support mechanisms 60 may be respectively disposed at the corner regions of the bottom plate 50 , or may also be disposed at the side edges of the bottom plate 50 .

[0069] In the above solution, by arranging the support mechanisms 60 at different positions, the heights of the bottom plate 50 at different positions can be adjusted, and the batteries 100 at different positions can be locked to the vehicle 1000 .

[0070] In some embodiments, a plurality of support mechanisms 60 are respectively disposed at corner regions of the bottom plate 50 .

[0071] Exemplarily, the bottom plate 50 is rectangular or square, and a support mechanism 60 is provided at each of the four corner regions of the bottom plate 50. If the bottom plate 50 is lifted up and the battery 100 is installed on the vehicle 1000, if it is found that a certain position of the battery 100 corresponding to the four support mechanisms 60 cannot be locked to the vehicle 1000 frame, it means that the vehicle 1000 frame at that location is deformed and twisted, and the corresponding position of the battery 100 needs to be lifted up separately to be locked successfully, then the corresponding support mechanism 60 can be adjusted separately.

[0072] In the above solution, by respectively arranging the support mechanisms 60 at the corner regions of the bottom plate 50 , the height of the corner regions can be adjusted so that each corner region of the battery 100 can be successfully locked on the vehicle 1000 .

[0073] Figure 6 A schematic structural diagram of a support mechanism from another angle provided for some embodiments of the present application.

[0074] like Figure 6 As shown, in some embodiments, the limiting member 62 includes a moving part 621 and a limiting block 622, and the moving part 621 is connected to the driving member 61; the limiting block 622 is arranged on the moving part 621, and the limiting block 622 is used to support the supporting member 64; the driving member 61 includes a driving body 611 and a pushing rod 612; the pushing rod 612 is connected to the driving body 611, and the pushing rod 612 is connected to the moving part 621.

[0075] The driving body 611 can be a motor, a cylinder or a hydraulic cylinder. The driving body 611 can drive the push rod 612 to extend and retract in the horizontal direction, thereby pushing the moving part 621 to move forward or backward. The limit block 622 can be arranged on the moving part 621 in a vertical state. When the driving body 611 drives the push rod 612 to move forward, the limit block 622 reaches the bottom of the support member 64, and the support member 64 is supported by the limit block 622, and the elastic member 63 cannot be compressed. When the driving body 611 drives the push rod 612 to move backward, the limit block 622 is separated from the support member 64, and the elastic member 63 can continue to be compressed.

[0076] In the above solution, the driving body 611 drives the push rod 612 to move, thereby driving the moving part 621 to move, so that the limit block 622 can lift the bottom plate 50 when the battery 100 cannot be locked successfully, which has a simple structure and reduces costs.

[0077] In some embodiments, the moving part 621 includes a connecting plate 623 and a moving plate 624, the connecting plate 623 is provided with a limiting groove 625, the moving plate 624 is connected to the connecting plate 623, and the limiting block 622 is provided on the moving plate 624; a sliding block 613 is provided on the pushing rod 612, and the sliding block 613 can be slidably connected to the limiting groove 625.

[0078] The connecting plate 623 can be connected to the movable plate 624 by bolts, buckles, etc. The connecting plate 623 can be L-shaped or U-shaped, and the push rod 612 and the connecting plate 623 are slidably connected.

[0079] The limiting groove 625 may be a strip groove, and the extending direction is the telescopic direction of the push rod 612. The limiting groove 625 may be a through hole, and one end of the slider 613 is connected to the push rod 612, and the other end abuts against the connecting plate 623 after passing through the strip groove.

[0080] In the above solution, by slidingly connecting the slider 613 of the push rod 612 with the limit groove 625 of the connecting plate 623 , the purpose of making the moving stroke of the moving plate 624 smaller than the minimum stroke of the push rod 612 can be achieved.

[0081] In some embodiments, a guide groove 626 is provided on the moving portion 621 , and the elastic member 63 passes through the guide groove 626 .

[0082] The guide groove 626 may also be a strip groove, and the extending direction is the moving direction of the moving plate 624. By setting the guide groove 626, the moving part 621 can be prevented from deflecting during the moving process.

[0083] In some embodiments, the support mechanism 60 further includes a base 65 , the base 65 is fixed to the bottom plate 50 , the elastic member 63 is connected between the base 65 and the support member 64 ; and the limiting member 62 is located on the base 65 .

[0084] The base 65 can be connected to the bottom plate 50 by means of bolts, pins or buckles. By providing the base 65, the position limiting member 62 can be better supported, and the position limiting member 62 is more stable when moving.

[0085] In some embodiments, there are multiple elastic members 63 , and the multiple elastic members 63 are respectively arranged at intervals.

[0086] In the above solution, by providing a plurality of elastic members 63 , the stability of the support member 64 can be improved.

[0087] In some embodiments, the battery exchange device 400 further includes a lifting mechanism, which is disposed on a side of the base plate 50 away from the supporting mechanism 60 .

[0088] The lifting mechanism may include a motor, a cylinder or a hydraulic cylinder, etc., to drive the base plate 50 to move up and down.

[0089] In the above scheme, the lifting mechanism drives the bottom plate 50 up and down, which can further improve the battery replacement efficiency.

[0090] Figure 7 A schematic diagram of the structure of the support mechanism provided in other embodiments of the present application.

[0091] like Figure 7 As shown, in some embodiments, the battery exchange device 400 also includes a first sensor 81, which is disposed beside the support member 64 and is used to detect the position of the support member 64.

[0092] The first sensor 81 may be a contact sensor or a proximity sensor, which is a sensor that can sense the position of the object to be measured and convert it into a usable output signal.
