Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Application No. 202022124649.8 and Chinese Application No. 202022121226.0, both filed on September 24, 2020. TECHNICAL FIELD The present disclosure relates to protection of a flat panel detector, and in particular, to a detector box for protecting a flat panel detector, and/or a mobile X-ray device provided with the detector box. BACKGROUND A mobile X-ray device is usually equipped with a flat panel detector, which can meet the imaging needs of various occasions and is flexible in application. Conventionally, the flat panel detector may be protected by a detector box. The detector box may be a box-like structure made of plastic or rubber with certain elasticity. Under the action of an external force, the detector box may be deformed appropriately, so that the flat panel detector can be directly clamped in the detector box. However, the detector box is inconvenient to use. It is desirable to provide a convenient device for protecting a flat panel detector. EP2755558B1 discloses a mobile radiography apparatus including rechargeable capabilities for at least one portable radiographic detector. SUMMARY An aspect of the present disclosure provides a device. The device may include a housing including an accommodating cavity and an insertion opening configured to allow insertion of a detector into the accommodating cavity. The device may also include a locking mechanism configured to prevent the detector from leaving the accommodating cavity. The device may also include a charging assembly arranged on the housing. The charging assembly may include a charging head and an elastic element configured to drive the charging head away from a charging port of the detector. In some embodiments, the locking mechanism may be arranged on one end of the insertion opening. A locking block may be arranged on a first end of the locking mechanism close to the insertion opening, and a second end of the locking mechanism away from the insertion opening may be configured to be lockable, so that the locking block has a locked state that prevents the detector from leaving the accommodating cavity. In some embodiments, the locking mechanism may include a driving rod and a locking assembly. The driving rod may be rotatably connected to the housing via a rotating shaft. The locking block may be arranged on a first end of the driving rod, and a locking groove may be arranged on a second end of the driving rod. The locking assembly may have a locked state in which the locking groove is connected with the locking assembly and an unlocked state in which the locking assembly is separated from the locking groove. In some embodiments, the locking assembly may include a telescopic shaft and a driving component, and the driving component may be configured to drive the telescopic shaft to move close to or away from the locking groove. In some embodiments, the driving component may include: a magnetic element configured to drive the telescopic shaft to move away from the locking groove when the magnetic element is energized; and a first elastic member. One end of the first elastic member may be connected with the telescopic shaft. The first elastic member may be configured to drive the telescopic shaft to move close to the locking groove when the magnetic element is powered off. In some embodiments, the locking assembly may include a supporting frame. The supporting frame may be arranged on the housing. The second end of the driving rod may be located closer to the supporting frame than the first end of the driving rod. The magnetic element may be arranged inside the supporting frame. A hole may be arranged on a wall of the supporting frame. The telescopic shaft movably may go through the hole. A first end of the first elastic member may be connected to the wall, and a second end of the first elastic member may be connected to the telescopic shaft. In some embodiments, the locking mechanism may include a second elastic member, a first end of the second elastic member may be connected to the housing, and a second end of the second elastic member may be connected to the driving rod, so that the locking block has an initial state that allows the detector to leave the accommodating cavity. In some embodiments, the second end of the second elastic member may be connected to a portion of the driving rod between the rotating shaft and the locking groove to tighten the second end of the driving rod away from the locking block, so that the locking block is driven to move away from the detector. In some embodiments, the second end of the second elastic member may be connected to a portion of the driving rod between the rotating shaft and the locking block to drive the locking block to move away from the detector. In some embodiments, a limit component may be disposed in the accommodating cavity and configured to limit a distance between the locking block and the detector when
