Protective cover, battery, power consuming device, and method for manufacturing protective cover

A protective cover, comprising:

• a first cover to be fixed to a frame of a battery, the first cover being provided with an accommodating cavity for accommodating a high-voltage lead-out structure, and the accommodating cavity having an opening for exposing the high-voltage lead-out structure;
• a second cover rotatably arranged on the first cover and the opening and respectively closing the opening when rotated relative to the first cover in a first direction of rotation and a second direction of rotation;
• and
• a cover closing structure connected to the first cover and the second cover, and causing the second cover to rotate in the second direction of rotation after the second cover is opened and an external force for opening the second cover is removed,
• wherein the cover closing structure comprises an elastic structure, the elastic structure is connected to the first cover and the second cover, and an elastic restoring force of the elastic structure drives the second cover to rotate in the second direction of rotation after the external force for opening the second cover is removed, and
• wherein the elastic structure comprises connecting pieces, and the second cover is rotatably connected to the first cover by means of the connecting pieces, such that the elastic restoring forces of the connecting pieces drive the second cover to rotate in the second direction of rotation after the external force for opening the second cover is removed.

• and
• a speed reducer,
• wherein the cover closing structure comprises an elastic structure, the elastic structure is connected to the first cover and the second cover, and an elastic restoring force of the elastic structure drives the second cover to rotate in the second direction of rotation after the external force for opening the second cover is removed,
• wherein the elastic structure comprises a spring, with a first end of the spring being connected to the first cover, and a second end of the spring being connected to the second cover, such that the second cover is rotated in the second direction of rotation in response to the elastic restoring force of the spring after the external force for opening the second cover is removed, and
• wherein the speed reducer is connected to the first cover and the second cover, and applies, when the cover closing structure causes the second cover to rotate in the second direction of rotation, an acting force to the second cover in the first direction of rotation to reduce a closing speed of the second cover.
