Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.

Referring to fig. 1 and 2, a flip cover 100 is provided in the embodiment of the present application, and is applied to an inverter module 200, where the inverter module 200 is used for converting dc power and ac power. The inverter module 200 can be matched with the battery pack 300 to form the energy storage device 400, the inverter module 200 is electrically connected with the battery pack 300, and the inverter module 200 can convert direct current of the battery pack 300 into alternating current for use by an electric appliance. As an exemplary example, the energy storage device 400 is a mobile power source, and is applied to a home stand-by field or an outdoor operation and entertainment field, etc., the energy storage device 400 can also be used in other fields where alternating current and direct current need to be converted, and the inverter module 200 and the battery pack 300 can be separately arranged or integrally arranged.

As shown in fig. 3 to 6, the inverter module 200 has a housing 210 and a socket 220, and the housing 210 is provided with an opening 230 for exposing the socket 220. The flip cover 100 includes a first cover part 10 and a second cover part 20 connected to each other, the first cover part 10 and the second cover part 20 are slidably connected to the housing 210 along the X direction, the second cover part 20 is located in the opening 230, the first cover part 10 can extend out of or retract into the opening 230 along the X direction, the first cover part 10 extending out of the opening 230 can rotate relative to the second cover part 20 along the axis of the Y direction, and the first cover part 10 retracting into the opening 230 is fixed relative to the second cover part 20. The flip cover 100 is configured to switch between a storage position and a covering position relative to the housing 210, when the flip cover 100 is in the covering position, as shown in fig. 5, the first cover portion 10 extends out of the opening 230 and rotates relative to the second cover portion 20 until the first cover portion 10 covers the opening 230, so that the first cover portion 10 covers the socket 220, thereby playing a role in dust-proof and water-proof for the socket 220; when the flip cover 100 is in the storage position, as shown in fig. 4, the first cover part 10 is retracted into the opening 230 to open the opening 230, thereby exposing the socket 220 for plugging a plug.

In the flip 100 provided by the application, the first cover portion 10 and the second cover portion 20 are slidably connected to the housing 210, and the first cover portion 10 can rotate relative to the second cover portion 20, so that not only can the first cover portion 10 be switched between the storage position and the covering position to prevent dust and water of the socket 220, but also the contact area between the flip 100 and the housing 210 is increased because the second cover portion 20 is always reserved in the opening 230, so that the second cover portion 20 plays a limiting role on the first cover portion 10, shaking of the first cover portion 10 in the telescopic process can be reduced, shaking of the first cover portion 10 in the external rotating process of the opening 230 can be reduced, and therefore stability of the first cover portion 10 and overall use feel of the flip 100 are improved. For example, if the second cover 20 is not provided, the first cover 10 extending out of the opening 230 is easy to rotate along the axis of the Z direction during operation, and slightly moves along the Z direction or the Y direction, so that the first cover 10 swings and cannot smoothly turn over or stretch, however, the existence of the second cover 20 can greatly reduce the swinging of the first cover 10, thereby improving stability and feel. Wherein the X direction, the Y direction and the Z direction are mutually perpendicular.

As shown in fig. 7-9, in some embodiments, flip cover 100 further includes a pin member 30, where pin member 30 passes through the overlap of first cover portion 10 and second cover portion 20 in the Y-direction to enable axial rotation of first cover portion 10 relative to second cover portion 20 about pin member 30.

As shown in fig. 7 to 10, in some embodiments, the pin member 30 rotates synchronously with the first cover part 10, and the peripheral side of the pin member 30 has two parallel flat surfaces 31, an arc surface 32 is connected between the two flat surfaces 31, and the diameter of the arc surface 32 is larger than the vertical distance between the two flat surfaces 31. The housing 210 is provided with a chute 240 and a circular groove 250 in the opening 230, the chute 240 extends along the X direction, the circular groove 250 is communicated with one end of the chute 240 near the opening 230, and the end of the pin member 30 is located in the chute 240 or the circular groove 250, i.e. the end of the pin member 30 can slide into the circular groove 250 from the chute 240 or slide into the chute 240 from the circular groove 250. The width of the chute 240 is greater than or equal to the distance between the two planes 31, the diameter of the circular groove 250 is the same as the diameter of the circular arc surface 32, and the diameter of the circular groove 250 is greater than the width of the connection between the chute 240 and the circular groove 250.

When the pin 30 slides into the circular groove 250 from the sliding groove 240, the circular groove 250 and the circular arc surface 32 have the same diameter, the circular arc surface 32 fully contacts the groove wall of the circular groove 250, the groove wall of the circular groove 250 plays a limiting role on the circular arc surface 32, so that the pin 30 can stably rotate in the circular groove 250, and the width of the sliding groove 240 is smaller than the diameter of the circular groove 250, so that the first cover 10 cannot accidentally slide into the sliding groove 240 during rotation, and the first cover 10 is limited in the circular groove 250, so that the first cover 10 can stably rotate after extending out of the opening 230, the shaking of the first cover 10 during rotation is avoided, and the using hand feel of the first cover 10 during rotation is further improved;

when the pin member 30 slides into the chute 240 from the circular groove 250, since the width of the connection between the chute 240 and the circular groove 250 is smaller than the diameter of the circular groove 250, the first cover 10 needs to be turned to be flush with the second cover 20 so that the two planes 31 are turned to be aligned with the walls of the chute 240, so that the pin member 30 can be pushed into the chute 240, and the first cover 10 is pushed into the opening 230 to expose the socket 220, thus avoiding the first cover 10 from accidentally entering the opening 230, so that the first cover 10 cannot accidentally retract into the opening 230 after extending out of the opening 230, and the first cover 10 can be switched to the storage position only when the first cover 10 is turned to be flush with the second cover 20, thereby improving the use feel of the first cover 10 in the covering position.

In some embodiments, the width of the sliding slot 240 is the same as the distance between the two planes 31, and when the pin member 30 slides along the sliding slot 240, the two planes 31 can fully contact the slot wall of the sliding slot 240 to play a limiting role, so that the first cover 10 is more stable when extending or retracting the opening 230 along the X direction, shaking of the first cover 10 is avoided, and thus the use feel of the first cover 10 is improved when the first cover 10 is pushed or pulled.

In other embodiments, the width of the sliding slot 240 gradually decreases along the direction from inside to outside of the opening 230, and the width of the connection between the sliding slot 240 and the circular slot 250 is equal to the distance between the two planes 31, so that after the pin member 30 enters the sliding slot 240, the pin member 30 can slide along the sliding slot 240 more smoothly, and the contact between the pin member 30 and the slot wall of the sliding slot 240 is reduced to reduce friction, so that the first cover 10 extends or retracts from the opening 230 to Cheng Gengjia smoothly along the X direction, and the use feel of the first cover 10 is improved when the first cover 10 is pushed or pulled.

In some embodiments, the pin member 30 includes a pin portion 33, the plane 31 and the circular arc surface 32 are disposed on the pin portion 33, the first cover portion 10 is provided with a first through hole 11, the second cover portion 20 is provided with a second through hole 21, the pin portion 33 passes through the first through hole 11 and the second through hole 21, the cross section of the first through hole 11 is the same as the cross section of the pin portion 33 so that the pin portion 33 rotates synchronously with the first cover portion 10, and the cross section of the second through hole 21 is circular and has the same diameter as the circular arc surface 32 so that the pin member 30 can rotate with the first cover portion 10 relative to the second cover portion 20.

In some embodiments, the pin member 30 further includes a stop portion 34, the first cover portion 10 is provided with the accommodating space 12, the stop portion 34 is located in the accommodating space 12, one end of the pin portion 33 is connected to the stop portion 34, and the other end of the pin portion 33 sequentially passes through the first through hole 11 and the second through hole 21. The flip 100 further includes an elastic member 40, the elastic member 40 is located in the accommodating space 12, the elastic member 40 abuts against the stop portion 34 towards the outside of the accommodating space 12, so that the pin member 30 can stretch and retract relative to the first cover portion 10 and the second cover portion 20, when the first cover portion 10 moves or rotates, the pin member 30 may generate vibration along the Y direction in the chute 240 or the circular groove 250, at this time, the pin member 30 can stretch and retract to a certain extent under the action of the elastic member 40, so that the elastic member 40 can absorb the vibration to play a role of buffering, and hard contact between the pin member 30 and the housing 210 is avoided, thereby further improving the hand feeling, and after the pin member 30 is retracted into the flip 100, the first cover portion 10 and the second cover portion 20 can be conveniently installed into the opening 230, so as to improve the installation efficiency.

In some embodiments, the housing 210 is provided with a protrusion 260 within the opening 230, the protrusion 260 extending in the X-direction. The second cover 20 is provided with a second groove 22 along the X direction, the protrusion 260 is inserted into the second groove 22, and the protrusion 260 guides the second cover 20 through the second groove 22, guiding the second cover 20 to slide along the length direction (X direction) of the protrusion 260. The first cover part 10 is provided with a first groove 13, when the first cover part 10 is rotated to the first groove 13 to align with the projection 260, the projection 260 can be inserted into the first groove 13, so that the first cover part 10 slides into the opening 230 along the length direction (X direction) of the projection 260, and the projection 260 also plays a guiding role on the first cover part 10 through the first groove 13, so that the first cover part 10 is guided to slide along the X direction.

In some embodiments, the first groove 13 is provided with a first expansion groove 131 at an end of the first cover part 10 facing the second cover part 20, and the first expansion groove 131 communicates with the first groove 13. The second groove 22 is provided with a second expansion groove 221 at an end of the second cover part 20 away from the first cover part 10, and the second expansion groove 221 communicates with the second groove 22. The width of the first expansion groove 131 gradually increases toward the second cover part 20, the width of the second expansion groove 221 gradually increases toward the direction facing away from the first cover part 10, the second expansion groove 221 makes it easier for the projection 260 to be inserted into the second groove 22 when the second cover part 20 is mounted to the opening 230, the first expansion groove 131 makes it easier for the projection 260 to be inserted into the first groove 13 when the first cover part 10 is retracted into the opening 230, i.e., the first expansion groove 131 guides the projection 260 into the first groove 13, and the second expansion groove 221 guides the projection 260 into the second groove 22.

In some embodiments, when the first cover 10 is fully extended out of the opening 230, the second recess 22 partially receives the protrusion 260, i.e., the end of the second recess 22 adjacent to the first cover 10 does not receive the protrusion 260, the second through hole 21 communicates with the end of the second recess 22 adjacent to the first cover 10, and only when the first cover 10 is turned flush with the second cover 20, one of the flat surfaces 31 of the pin member 30 is flush with the groove wall of the second recess 22 to allow the protrusion 260 to be inserted into the second recess 22, thereby allowing the first cover 10 to be shifted to the receiving position, otherwise the circular arc surface 32 of the pin member 30 would enter the second recess 22 to prevent the protrusion 260 from being inserted into the second recess 22, thereby avoiding the situation that the first cover 10 accidentally enters the opening 230, so that the first cover 10 would not accidentally retract into the opening 230 after extending out of the opening 230, and only when the first cover 10 is turned flush with the second cover 20 would the first cover 10 be shifted to the receiving position, thereby improving the feel of the first cover 10 in the covering position.

In some embodiments, the width of the protrusion 260 gradually increases along the direction from inside to outside of the opening 230, and the width of the end of the protrusion 260 near the outside of the opening 230 is the same as the width of the first groove 13 and the second groove 22, so that during the process of retracting the first cover 10 into the opening 230, the end of the protrusion 260 near the outside of the opening 230 can always guide the movement of the first cover 10 through the groove wall of the first groove 13, so as to avoid the shake of the first cover 10 along the Z direction, and the contact between the second cover 20 and the protrusion 260 gradually decreases, thereby gradually reducing friction and further making the movement of the first cover 10 smoother; in the process of extending the opening 230 from the first cover portion 10, the contact between the second cover portion 20 and the protrusion 260 is gradually increased, so that the friction is gradually increased until one end of the protrusion 260, which is close to the outer side of the opening 230, limits the second cover portion 20 through the groove wall of the second groove 22, so that the movement of the first cover portion 10 is more stable, and the hand feeling of pushing and pulling the first cover portion 10 is improved.
