[0028] In some embodiments of this application, a battery swapping cabinet is provided, which is applied in the field of battery swapping technology for electric vehicles. The battery swapping cabinet is configured to store fully charged batteries and depleted batteries. A battery rack 100 is provided inside the battery swapping cabinet for placing batteries. Figure 1 This is a structural diagram of the battery holder 100. Figure 2 This is a partial structural diagram of the battery holder 100.

[0029] The battery rack 100 includes a frame 180 and a charging socket 200. The frame 180 has multiple placement spaces 110 for placing batteries. For example, the multiple placement spaces 110 are arranged vertically. The charging socket 200 is disposed on the frame 180 and is used to connect to the charging port of the battery. Figure 3 This is a structural diagram of a charging socket 200.

[0030] A rechargeable battery has a charging port on its top. Correspondingly, the charging socket 200 of this application is located on top of the placement space 110. The charging socket 200 can move up and down to mate with or detach from the charging port, thus meeting the battery's top charging requirements.

[0031] The charging socket 200 includes a fixed frame 210, a movable frame 220, a drive unit 230, and a socket body 240. The movable frame 220 is slidably connected to the fixed frame 210. The drive unit 230 is configured to drive the movable frame 220 to move up and down. The socket body 240 is mounted on the movable frame 220 and is configured to move up and down to engage or disengage with the battery.

[0032] During charging, the depleted battery enters the placement space 110 of the battery holder 100. At this time, the socket body 240 is positioned above the battery, with a certain distance between it and the top of the battery. After the battery is fully inserted, the socket body 240 moves down to align with the charging port on the top of the battery, thus establishing a circuit connection. After charging is complete, the socket body 240 moves up to detach from the charging port, and the circuit is disconnected.

[0033] This application achieves compatibility with batteries using the top charging socket by placing the charging socket 200 at the top of the battery placement space 110 and configuring the drive unit 230 to drive the socket body 240 to move up and down. After the battery enters the placement space 110 and is in place, the socket body 240 can move down to connect with the top socket of the battery. After charging is completed, it moves up to separate, thus achieving compatibility with batteries using the top charging socket.

[0034] This application integrates the charging socket 200 directly into the frame 180 of the battery holder 100, and utilizes the unused top area of ​​the placement space 110, without occupying additional horizontal space, resulting in a compact structure.

[0035] In some embodiments of this application, reference is made to Figure 3 The drive unit 230 is an electric actuator. The drive motor of the electric actuator is fixedly connected to the fixed frame 210 by bolts or other means. The actuator rod is fixedly connected to the movable frame 220 by bolts or other means.

[0036] When the drive motor drives the push rod to rise, the push rod drives the movable frame 220 to rise, thereby raising the socket body 240 and separating the socket body 240 from the charging port on the top of the battery. When the drive motor drives the push rod to fall, the push rod drives the movable frame 220 to fall, thereby lowering the socket body 240 and connecting it with the charging port on the top of the battery.

[0037] In some other embodiments, the drive unit 230 may also adopt a structure such as a screw jack or a rack and pinion.

[0038] In some embodiments of this application, reference is made to Figure 3 The fixed frame 210 is equipped with a slide rail 261, and the movable frame 220 is equipped with a sliding part 262. The slide rail 261 and the sliding part 262 are slidably connected. For example, the sliding part 262 is a slider. Through the sliding connection between the slide rail 261 and the sliding part 262, the movable frame 220 is slidably positioned on the fixed frame 210, thereby improving the lifting reliability of the movable frame 220.

[0039] In some embodiments of this application, reference is made to Figure 3 The movable frame 220 includes a first sub-movable frame 221 and a second sub-movable frame 222 that are fixedly connected. The first sub-movable frame 221 is slidably connected to the fixed frame 210 and is connected to the drive unit 230. The second sub-movable frame 222 extends into the space where the battery is located and is connected to the socket body 240.

[0040] Specifically, the first sub-moving frame 221 is provided with a sliding part 262, and the first sub-moving frame 221 and the fixed frame 210 are slidably connected through the two sliding parts. The first sub-moving frame 221 is fixedly connected to the push rod. The first sub-moving frame 221 and the second sub-moving frame 222 have an L-shaped structure, the second sub-moving frame 222 extends in the horizontal direction, and the socket body 240 is fixedly installed on the second sub-moving frame 222.

[0041] In some embodiments of this application, a displacement detection unit is provided on the fixed frame 210. The displacement detection unit is configured to detect the vertical displacement of the movable frame 220 and monitor the vertical displacement data of the movable frame 220 in real time, so as to realize dynamic control and abnormal early warning of the movement process of the socket body 240.

[0042] In some embodiments of this application, the displacement detection unit includes an upper proximity switch 251 and a lower proximity switch 252, both of which are mounted on the fixed frame 210. An extension 223 is provided on the movable frame 220. For example, the first sub-moving frame 221 is provided with the extension 223, which is a protruding elongated strip-shaped structure. The upper proximity switch 251 and the lower proximity switch 252 are configured to detect the movement position of the extension 223.

[0043] When the movable frame 220 rises to the target position, the upper proximity switch 251 detects the position of the extension 223, the system control drive unit 230 stops working, and the movable frame 220 stops rising to prevent it from interfering with the placement of batteries on the upper layer. When the movable frame 220 descends to the target position, the lower proximity switch 252 detects the position of the extension 223, the system control drive unit 230 stops working, and the movable frame 220 stops descending to prevent it from crushing the batteries.

[0044] In some embodiments of this application, reference is made to Figure 1 and Figure 4 The side of the placement space 110 is provided with a side stop 120, which is configured to limit the lateral displacement of the battery, that is, the left and right displacement.

[0045] The side guard 120 includes a plurality of side guard wheels 121, which make rolling contact with the side of the battery, facilitating the battery to enter and exit the placement space 110 and reducing friction.

[0046] The side guard 120 also includes a guide member 122, which has a guide slope and is disposed on the end side of the placement space 110 to guide the battery in and out.

[0047] In some embodiments of this application, reference is made to Figure 1The bottom of the placement space 110 is provided with support wheels 130. The support wheels 130 make rolling contact with the bottom side of the battery, which facilitates the battery to enter and exit the placement space 110 and reduces friction.

[0048] In some embodiments of this application, reference is made to Figure 1 The frame 180 includes four columns 140, and each column 140 is provided with multiple crossbeams 150 arranged at intervals along the height direction. The four crossbeams 150 on the same plane constitute a support frame for carrying the battery. A support beam 160, a side wheel 121, and a side stop 120 are provided between two adjacent crossbeams 150 along the front-back direction of the battery entry and exit.

[0049] In some embodiments of this application, a rear stop 170 is provided on the rear crossbeam 150 to limit the rearward movement of the battery.

[0050] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
