DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] The terms "first", "second", etc. in the specification of the utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The utility model provides a battery swap station to solve the problem that the existing battery swap stations can only be compatible with one type of battery unlocking mechanism and are not compatible with different types of battery unlocking mechanisms.

[0046] like Figures 1 to 3 As shown, the embodiment of the utility model provides a battery swap station, comprising:

[0047] A grasping device 1 and a storage device 2, wherein the storage device 2 is arranged to semi-surround the grasping device 1, wherein the number of the storage devices 2 can be one or more, for example, three storage devices 2 are arranged, and the grasping device 1 is rectangular in shape when viewed from above, and the three storage devices 2 are respectively surrounded on three sides of the grasping device 1 to facilitate the grasping device 1 to grasp in the storage device 2.

[0048] Among them, the storage device 2 stores different types of locking and unlocking mechanisms 3 and different types of power batteries 4. Specifically, the storage device 2 is formed into a frame structure and has different layers of storage brackets. Each layer of storage brackets stores the locking and unlocking mechanisms 3 or power batteries 4 and has good compatibility, so that when different types of locking and unlocking mechanisms 3 or power batteries 4 are added later, storage brackets can be directly added.

[0049] The storage device 2 may be in the form of a shelf.

[0050] Among them, the locking and unlocking mechanism 3 (or called the locking and unlocking platform) includes a locking and unlocking rod and a driving member connected to the locking and unlocking rod, the driving member is used to drive the locking and unlocking rod to move, and the locking and unlocking rod is used to lock the power battery in the storage device to the battery swap vehicle (i.e., install and lock) or unlock the power battery on the battery swap vehicle (i.e., unlock and disassemble).

[0051] It should also be noted that the locking and unlocking mechanism 3 also has the ability to carry and position the power battery.

[0052] By making different types of locking and unlocking mechanisms 3 and different types of power batteries 4 compatible in the storage device 2, if other types of locking and unlocking mechanisms 3 or power batteries 4 need to be added later, it is only necessary to add a storage bracket to the storage device 2, which has better compatibility and integration, and the locking and unlocking mechanisms 3 and power batteries 4 are stored separately, which increases adaptability and reduces the cost of the battery swap station. Among them, different types of locking and unlocking mechanisms can also be understood as locking and unlocking mechanisms of different specifications, and different types of power batteries can also be understood as power batteries of different specifications.

[0053] A controller (or control device) and an identification sensor, the controller is connected to the identification sensor and the gripping device 1 respectively, wherein the identification sensor is arranged at the battery installation position, which is the position where the battery-swapping vehicle performs battery swapping, and the identification sensor is used to send an identification signal to the controller for indicating the model of the power battery on the battery-swapping vehicle. Specifically, after the battery-swapping vehicle stops at the battery installation position, the identification sensor can identify the model of the battery-swapping vehicle and then determine the model of the power battery on the battery-swapping vehicle, and then send an identification signal to the controller.

[0054] Alternatively, the identification sensor can also be installed in front of the battery swap station, or installed on the driving path of the battery swap vehicle at the battery swap station. Before the battery swap vehicle enters the battery swap station, the identification sensor can identify the model of the battery swap vehicle and then determine the model of the power battery on the battery swap vehicle. Alternatively, during the driving of the battery swap vehicle, the identification sensor can identify the model of the battery swap vehicle and then determine the model of the power battery on the battery swap vehicle.

[0055] The controller is used to receive the identification signal and send a grabbing signal to the grabbing device 1, and the grabbing signal is used to instruct the grabbing device 1 to grab the locking and unlocking mechanism 3 corresponding to the model of the power battery 4 on the battery swap vehicle and grab the power battery 3 in the storage device 2 that is the same model as the power battery 3 on the battery swap vehicle (which can be understood as a fully charged power battery).

[0056] After the controller receives the identification signal sent by the identification sensor, the model of the power battery 4 on the battery swap vehicle is determined according to the identification signal, and a grabbing signal is sent to the grabbing device 1 according to the model of the power battery 4 on the battery swap vehicle. The grabbing device 1 searches for the locking and unlocking mechanism 3 corresponding to the model of the power battery 4 on the battery swap vehicle in the storage device 2 and grabs it according to the grabbing signal, and searches for the power battery 4 with the same model as the power battery 4 on the battery swap vehicle in the storage device 2 and grabs it. Among them, the locking and unlocking mechanism 3 corresponding to the model of the power battery 4 on the battery swap vehicle can be understood as the locking and unlocking mechanism 3 being able to unlock the power battery 4 on the battery swap vehicle.

[0057] The transfer device 5 is arranged on the side of the grasping device 1 that is not surrounded by the storage device 2.

[0058] Specifically, after the controller sends a grabbing signal to the grabbing device 1, the grabbing device 1 grabs the locking and unlocking mechanism 3 corresponding to the model of the power battery 4 on the battery-swap vehicle according to the grabbing signal and places it on the transfer device 5. The transfer device 5 transports the locking and unlocking mechanism 3 to the battery installation position. After that, the locking and unlocking mechanism 3 unlocks the power battery 4 on the battery-swap vehicle. After that, the transfer device 5 transports the locking and unlocking mechanism 3 out of the battery installation position to the initial position (the initial position is the position of the transfer device 1 when the grabbing device 1 grabs the locking and unlocking mechanism 3 and the power battery 4 in the storage device 1 and can be placed in the transfer device 1), so that the grabbing device 1 The structure grabs the locking and unlocking mechanism 3 and puts it back to its original position, and the transfer device 5 sends the power battery 4 on the battery swapping vehicle to the initial position at the battery installation position, so that the grabbing mechanism grabs the power battery 4 on the battery swapping vehicle and puts it into the vacant position in the storage device 2 for charging. After that, the grabbing device 1 grabs the power battery 4 of the same model as the power battery 4 on the battery swapping vehicle according to the grabbing signal and places it on the transfer device 5, and the transfer device 5 transports the power battery 4 to the battery installation position. After that, the transfer device 5 transports the previous locking and unlocking mechanism 3 to the battery installation position, so that the locking and unlocking mechanism 3 locks the power battery 4 in the storage device to the battery swapping vehicle.

[0092] By replacing the locking and unlocking mechanisms with different requirements, the battery of electric vehicles with different battery locks can be replaced, thereby achieving the purpose of compatibility. Since the same platform is used separately at the same time, the integration of the locking and unlocking stations is reduced, and the failure rate and maintenance cost and difficulty are effectively reduced. Because the locking and unlocking mechanisms are relatively independent structures, the types of locking and unlocking mechanisms can be increased at any time, further increasing adaptability and reducing overall costs.

[0093] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary personnel in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention.
