Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a cover assembly and energy storage device. Background Technology

[0002] The outer casing of an energy storage power supply is usually connected to a flip cover. The flip cover can expose or cover the interface of the energy storage power supply. The flip cover slides or rotates relative to the outer casing. When the flip cover is in the storage position and exposes the interface, the outer casing needs to be provided with a receiving space for storing the flip cover, which results in occupying too much space inside the energy storage power supply. Summary of the Invention

[0003] In view of this, it is necessary to provide a cover assembly that reduces the space occupied.

[0004] Some embodiments of this application provide a cover assembly, which includes a base and a flip cover. The base has a receiving cavity and an operating port. The flip cover includes a first cover and a second cover, which are configured to move from the receiving cavity to the operating port. The first cover and the second cover are stacked within the receiving cavity, and are stacked or at least partially offset at the operating port to cover part or all of the operating port area.

[0005] In the aforementioned cover assembly, the first and second covers are stacked, reducing the length of the receiving cavity compared to when the first and second covers are staggered or relatively unfolded. This reduces the internal space occupied by the receiving cavity, which is beneficial for the internal space layout of the device. Simultaneously, it ensures that the second cover, stacked or staggered with the first cover, covers the operating opening. The first and second covers can be at least partially staggered within the operating opening, thus flexibly changing the area of ​​the operating opening covered.

[0006] According to some embodiments of this application, the first cover has a receiving area, the second cover is accommodated in the receiving area when stacked with the first cover, and at least partially exits the receiving area when at least partially offset from the first cover.

[0007] When the second cover is stacked with the first cover, it is housed within the receiving area. The second cover does not occupy additional space in the receiving cavity, further reducing the volume of the first and second covers stacked together, which is more conducive to saving space inside the equipment.

[0008] According to some embodiments of this application, the first cover and the second cover are configured to lock within the receiving cavity and unlock within the operating port.

[0009] The aforementioned locked first and second covers can move simultaneously to ensure the stacked arrangement of the flip-top portion within the receiving cavity, thereby reducing the space occupied during the flip-top movement. The first and second covers can be unlocked at the access port and move relative to each other, facilitating the covering of the access port.

[0010] According to some embodiments of this application, the second cover includes a main body, a deformable portion, and a mating portion. The deformable portion is connected to the main body, and the mating portion is connected to the deformable portion. The first cover has a through hole. The mating portion is configured to be positioned within the through hole by being stopped by the hole wall when inserted into the through hole, thereby locking the first cover and the second cover. The deformable portion is configured to deform under force to disengage the mating portion from the through hole, thereby unlocking the first cover and the second cover.

[0011] The cooperation of the aforementioned mating parts and deformation parts enables the locking and unlocking of the first cover and the second cover.

[0012] According to some embodiments of this application, the second cover includes a main body, a deformable portion, and a mating portion. The mating portion is slidably connected to the main body, and the deformable portion abuts against the main body and the mating portion. The first cover has a through hole. The mating portion is configured to be stopped and positioned within the through hole by the hole wall when inserted into the through hole, thereby locking the first cover and the second cover. The deformable portion is configured to deform under force to disengage the mating portion from the through hole, thereby unlocking the first cover and the second cover.

[0013] The cooperation of the aforementioned mating parts and deformation parts enables the locking and unlocking of the first cover and the second cover.

[0014] According to some embodiments of this application, the base body has a protrusion located at the operating port; a through hole penetrates the side of the first cover body facing the base body when it rotates toward the operating port. At least a portion of the protrusion engages with the through hole when the first cover body rotates into the operating port, and at least a portion of the mating part is pushed out of the through hole.

[0015] In the above embodiments, the protrusion engages with the through hole, which helps to stabilize the first cover within the operating opening. The protrusion engaging with the through hole allows the mating part to be pushed out of the through hole, unlocking the first and second covers. This saves the user the effort required to push or pull the second cover to cover the operating opening, making the cover assembly easier to operate.

[0016] According to some embodiments of this application, when the protrusion is rotated into the operating port of the first cover, it is engaged in the through hole. The end of the mating part away from the deformable part is provided with a guide part. When the protrusion abuts against the mating part, the guide part is located in the through hole. The guide part moves along the hole wall of the through hole by the force of the second cover, so that the mating part is disengaged from the through hole.

[0017] In the above embodiments, the guide portion can easily slide along the wall of the through hole, reducing the unlocking force of the first cover and the second cover, making the cover assembly easy to operate.

[0018] According to some embodiments of this application, the deformable part is configured to elastically deform under the driving force of the movement of the second cover relative to the first cover when the first cover is positioned in the operating port, so that the mating part exits the through hole.

[0019] In the above embodiments, the elastic deformation caused by the movement of the second cover relative to the first cover allows the mating part to disengage from the unlocking method of the through hole, which helps to simplify the structure of the cover assembly.

[0020] According to some embodiments of this application, a guide portion is provided at the end of the mating part opposite to the deformable part. The seat body has a protrusion located at the operating port. The guide portion can protrude from the side of the first cover body opposite to the deformable part. The mating part is configured to move towards the protrusion under the action of the first cover body moving within the operating port, and is pressed by the protrusion to cause the deformable part to elastically deform, causing the guide portion to retract into the through hole. The guide portion located within the through hole moves along the hole wall of the through hole under the action of the force of the second cover body, causing the mating part to exit the through hole.

[0021] The aforementioned guide portion protrudes from the side of the first cover away from the deformation portion and does not contact the wall of the through hole, thereby reducing the risk of the first cover and the second cover separating due to the sliding of the guide portion against the wall of the through hole when they move in the receiving cavity, and thus improving the locking stability of the first cover and the second cover.

[0022] According to some embodiments of this application, the seat body has a first groove that connects the receiving cavity and the operating port. A mating portion protrudes from the side of the first cover body opposite to the deformable portion and is located within the first groove. The protrusion is configured such that the seat body is located on the outer periphery of the first groove and on the sidewall within the operating port.

[0023] The aforementioned guide portion is located within the first groove, and the mating portion does not interfere with the seat body, reducing frictional resistance and improving the smoothness of movement of the first cover and the second cover within the receiving cavity.

[0024] According to some embodiments of this application, the first cover is provided with a second groove, which communicates with a through hole. After the mating part exits the through hole, it enters the second groove and slides within the second groove.

[0025] The aforementioned mating part slides within the second groove without disengaging from it, thus ensuring that the second cover does not detach from the first cover and maintains the integrity of the cover assembly.

[0026] According to some embodiments of this application, the second cover is provided with an operating part, and when the first cover and the second cover are stacked in the receiving cavity, the operating part is located outside the receiving cavity.

[0027] The aforementioned operating part facilitates the push and pull of the cover assembly by the operator. When the first cover and the second cover are stacked, pulling the operating part will sequentially move the second cover and the first cover. Furthermore, when the first cover exits the receiving cavity, pulling the operating part will move the second cover relative to the first cover. The operating part is always located outside the receiving cavity, eliminating the need to provide separate operating parts on the first and second covers, thus simplifying the structure.

[0028] According to some embodiments of this application, the first cover is configured to rotate into the operating port after exiting the receiving cavity.

[0029] The first cover body drives the second cover body to rotate to the operating port, so that the cover assembly occupies space in two directions, minimizing the size in the same direction, which is conducive to the space utilization of the cover assembly when it is installed in the equipment.

[0030] According to some embodiments of this application, the base body is provided with a first groove and a first shaft hole. The first groove connects a receiving cavity and an operating port, and the first shaft hole is located at one end of the first groove that connects to the operating port. The first cover body includes a cover member and a cover shaft. The cover shaft is connected to the cover member and slides within the first groove. The cover shaft is at least partially elastically deformable to engage with the first shaft hole from the first groove and is rotatable within the first shaft hole.

[0031] The aforementioned cover shaft is engaged and confined within the first shaft hole, preventing the first cover from detaching from the base. The cover shaft rotates within the first shaft hole, allowing the first and second covers to rotate into the operating port without being stopped by the cavity wall after exiting the receiving cavity, thus effectively blocking the operating port.

[0032] According to some embodiments of this application, the cover shaft includes a connecting telescopic portion and a retaining shaft. The cover member is provided with a mounting portion, and the telescopic portion is mounted on the mounting portion. The telescopic portion extends in a wavy shape and is capable of elastically extending and retracting along the axial direction of the retaining shaft. The retaining shaft passes through the mounting portion and enters a first groove or a first shaft hole.

[0033] The aforementioned wavy extension of the telescopic part is highly elastic, which can easily improve the stability of the locking shaft in the first groove and the first shaft hole, thereby improving the stability of the first cover and the second cover moving in the receiving cavity and rotating in the operating port.

[0034] According to some embodiments of this application, a first cover is provided with a second groove, and a second cover is slidably connected to the second groove, and when stacked with the first cover to cover the operating opening, it is located on the side of the first cover facing the base. The second groove includes a first segment and a second segment arranged in sequence, with the second segment inclined relative to the first segment. When the second cover slides from the first segment to the second segment, it moves toward the side of the first cover away from the base when covering the operating opening.

[0035] The second segment is inclined relative to the first segment. The mating part moves sequentially along the first and second segments, causing the second cover to move away from the base when it slides from the first segment to the second segment and covers the operating opening with the first cover. The second cover and the first cover unfold relative to each other. The mating part moves sequentially along the second and first segments, causing the second cover to move towards the base when it covers the operating opening with the first cover, thereby gradually stacking the second cover with the first cover.

[0036] According to some embodiments of this application, a first cover has a first inclined surface, and a second cover has a second inclined surface. The first and second inclined surfaces are capable of sliding relative to each other and abut against each other when the first and second covers are unfolded relative to each other.

[0037] The abutment of the first and second inclined surfaces improves the overall strength of the cover assembly and enhances the continuity between the first and second covers, thereby improving the sealing of the operating port by the first and second covers and enhancing the protective effect of the cover assembly on the interface inside the operating port.

[0038] According to some embodiments of this application, the first cover is further provided with an abutting surface, and the second cover is provided with an abutting portion, which abuts against the abutting surface when the first cover and the second cover are unfolded relative to each other.

[0039] The contact between the aforementioned contact portion and the contact surface increases the strength of the first cover and the second cover.

[0040] According to some embodiments of this application, the second cover is provided with a pin, and the seat is provided with a third groove and a second shaft hole that communicate with the operating port. The second shaft hole is located at the end of the third groove away from the receiving cavity, and the end of the third groove facing the receiving cavity forms an opening.

[0041] The second cover is configured such that, when it moves relative to the first cover within the operating port, the pin enters the third groove from the opening and slides along the third groove until it engages with the second shaft hole.

[0042] The aforementioned pin can slide within the third groove to change the area of ​​the second cover covering the operating opening, and when engaged in the second shaft hole, it can stably maintain the entire area of ​​the operating opening covered by the first and second covers.

[0043] One embodiment of this application also provides a cover assembly, which includes a base and a flip cover. The flip cover includes a first cover and a second cover. The base has a receiving cavity and an operating opening. The first cover is configured to move from the receiving cavity to the operating opening and cover a portion of the operating opening. When the first cover is located at the operating opening, the second cover is configured to move relative to the first cover from an initial position to an unfolded position. When the second cover moves to the unfolded position, it covers another portion of the operating opening.

[0044] In the aforementioned cover assembly, the first cover and the second cover are stacked together. Compared to when the first cover and the second cover are staggered or unfolded relative to each other, the length of the receiving cavity is reduced. The receiving cavity occupies the internal space of the device. The length occupied by the flip cover in the receiving cavity is reduced, which is beneficial to the internal space layout of the device. At the same time, it ensures that the second cover and the first cover cover the operating port.

[0045] One embodiment of this application also proposes an energy storage device. The energy storage device includes an electrically connected battery pack and interface, a housing, and a cover assembly. The cover assembly includes a base and a flip cover. The base has a receiving cavity and an operating port. The flip cover includes a first cover and a second cover, configured to move from the receiving cavity to the operating port. The first and second covers are stacked within the receiving cavity, and at the operating port, they are stacked or at least partially offset to cover part or all of the operating port area. The battery pack is disposed within the housing, which has a mounting opening through which the interface protrudes. The base is connected to or formed into the housing.

[0046] In the aforementioned energy storage device, the first and second covers are stacked, reducing the length of the receiving cavity compared to when the first and second covers are staggered or relatively unfolded. This reduces the internal space occupied by the receiving cavity, which is beneficial for the internal space layout of the device. Simultaneously, it ensures that the second cover, stacked or staggered with the first cover, covers the operating opening. The first and second covers can be at least partially staggered within the operating opening, thus flexibly changing the area of ​​the operating opening covered. Attached Figure Description

[0060] The implementation of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0062] Some embodiments of this application disclose a cover assembly including a base and a flip cover. The base has a receiving cavity and an operating port. The flip cover includes a first cover and a second cover, which are configured to move from the receiving cavity to the operating port. The first cover and the second cover are stacked within the receiving cavity, and are stacked or at least partially offset at the operating port to cover part or all of the operating port area.

[0063] In the aforementioned cover assembly, the first and second covers are stacked, reducing the length of the receiving cavity compared to when the first and second covers are staggered or relatively unfolded. This reduces the internal space occupied by the receiving cavity, which is beneficial for the internal space layout of the device. Simultaneously, it ensures that the second cover, stacked or staggered with the first cover, covers the operating opening. The first and second covers can be at least partially staggered within the operating opening, thus flexibly changing the area of ​​the operating opening covered.

[0064] The following section, in conjunction with the accompanying drawings, provides a detailed description of some embodiments of this application. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0065] Please see Figure 1 and Figure 2 One embodiment of this application provides a cover assembly 100. The cover assembly 100 is used to cover or expose an interface 400 of a device (e.g., an energy storage device 500, a cleaning device, a medical device, a server, etc.), such as a power interface 400 or a signal transmission interface 400. The cover assembly 100 can protect the interface 400 when it is not in use and expose the interface 400 when it is in use.

[0066] This application also proposes an energy storage device 500. The energy storage device 500 includes a battery pack, an interface 400, a housing 300, and a cover assembly 100. The battery pack is installed inside the housing 300. The housing 300 has a mounting opening 301. The interface 400 protrudes from the mounting opening 301 and is electrically connected to the battery pack. The cover assembly 100 is installed in the mounting opening 301 and is used to cover or expose the interface 400.

[0067] The cover assembly 100 includes a base 10 and a flip cover 20. The base 10 is connected to the mounting port 301 of the housing 300. It is understood that in other embodiments, the base 10 may also be integrally formed with the housing 300. The base 10 is provided with a receiving cavity 101 and an operating port 102. The operating port 102 is at least partially opposite to the mounting port 301, thereby allowing the operating port 102 to also be exposed to the interface 400.

[0068] Please continue reading. Figure 3 The flip cover 20 includes a first cover 21 and a second cover 23. The first cover 21 and the second cover 23 are configured to be movable from the receiving cavity 101 to the operating port 102, and are stacked within the receiving cavity 101, and are stacked or at least partially offset within the operating port 102. The stacked first cover 21 and the second cover 23 are located at the portion of the operating port 102 that covers the operating port 102, such as... Figure 4 As shown, with the first cover 21 and the second cover 23 staggered, the area of ​​the flip cover 20 that can cover the operation opening 102 increases until the flip cover 20 completely covers the operation opening 102, as shown. Figure 5 As shown.

[0069] In one embodiment, the first cover 21 and the second cover 23 are partially offset to cover the entire operation opening 102. It can be understood that in other embodiments, the first cover 21 and the second cover 23 can also be completely offset to cover the entire operation opening 102. That is, when the second cover 23 moves from the initial position to the unfolded position relative to the first cover 21, the first cover 21 covers a part of the operation opening 102, and the second cover 23 covers another part of the operation opening 102.

[0070] The device (e.g., energy storage device 500) can have multiple interfaces 400 at the mounting port 301. The operating port 102 can selectively expose some of the interfaces 400. Correspondingly, the flip cover 20 only needs to cover the interfaces 400 that do not need to be exposed. It can be understood that when the device has only one interface 400 at the mounting port 301, the flip cover 20 can cover the entire operating port 102 by staggering the first cover 21 and the second cover 23.

[0071] The first cover 21 and the second cover 23 are stacked together. Compared with the first cover 21 and the second cover 23 being staggered or unfolded relative to each other, the length of the receiving cavity 101 occupied by the receiving cavity 101 is reduced. The receiving cavity 101 will occupy the internal space of the device. The length occupied by the flip cover 20 in the receiving cavity 101 is reduced, which is beneficial to the internal space layout of the device. At the same time, it ensures the purpose of covering the operation port 102 by stacking or staggering the second cover 23 and the first cover 21.

[0072] Please see Figure 6In one embodiment, the first cover 21 is provided with a receiving area 201. When the second cover 23 is stacked with the first cover 21, it is housed in the receiving area 201. The second cover 23 does not occupy additional space in the receiving cavity 101, further reducing the volume of the first cover 21 and the second cover 23 stacked, which is more conducive to saving space in the device.

[0073] It is understood that in other embodiments, the accommodating area 201 may also be omitted. For example, the first cover 21 and the second cover 23 may also be two plate-like structures, which are slidably connected by a slide rail and a slider structure between the first cover 21 and the second cover 23, thereby completing different states of stacking and staggered arrangement.

[0074] Please see Figures 2 to 4 The first cover 21 is configured to rotate into the operating port 102 after exiting the receiving cavity 101. In one embodiment, the base 10 includes a first body 11 and a second body 12. The second body 12 is generally perpendicularly connected to one side of the first body 11, making the base 10 generally L-shaped. One side of the second body 12 is recessed to form the operating port 102, and the operating port 102 extends through a portion of one side of the second body 12 so that the operating port 102 can expose the interface 400. The first body 11 is provided with the receiving cavity 101, and the receiving cavity 101 extends through one side of the first body 11 to communicate with the operating port 102. The first body 11 can isolate the flip cover 20 from other structures within the device. It is understood that in other embodiments, the first body 11 may also be a U-shaped plate structure, with the flip cover 20 exposed within the device.

[0075] The first cover 21 drives the second cover 23 to rotate to the operating port 102, so that the cover assembly 100 occupies space in two directions, minimizing the size in the same direction, which is beneficial to the space utilization of the cover assembly 100 when it is installed in the equipment.

[0076] Please see Figure 6 The base 10 is provided with a first groove 103 and a first shaft hole 104. The first groove 103 extends from the receiving cavity 101 to the operating port 102, thereby connecting the receiving cavity 101 and the operating port 102. The first shaft hole 104 is located at the end of the first groove 103 that connects to the operating port 102.

[0077] The first cover 21 includes a cover member 211 and a cover shaft 213. The cover shaft 213 is connected to the cover member 211 and slides within a first groove 103. The cover shaft 213 is at least partially elastically deformable to engage with a first shaft hole 104 from the first groove 103 and is rotatable within the first shaft hole 104.

[0078] In one embodiment, the bottom wall of the first shaft hole 104 is farther away from the bottom wall of the first groove 103 than the first cover 21. The cover shaft 213 is not stopped by the bottom wall of the first groove 103 and elastically engages in the first shaft hole 104, so that the cover shaft 213 is confined within the first shaft hole 104 and the first cover 21 will not detach from the seat 10. The cover shaft 213 rotates within the first shaft hole 104, so that after the first cover 21 and the second cover 23 exit the receiving cavity 101, they can rotate into the operating port 102 without the cavity wall of the receiving cavity 101 stopping them, thereby achieving the blocking of the operating port 102.

[0079] It is understood that in other embodiments, the cover shaft 213 is integrally formed with the cover member 211. For example, the cover shaft 213 includes an elastic arm protruding from the cover member 211 and a shaft portion (not shown) located at one end of the elastic arm.

[0080] It is understood that in other embodiments, the first cover 21 and the second cover 23 may also detach from the base 10 and separate from each other when exiting the receiving cavity 101, and then the first cover 21 and the second cover 23 may be respectively installed into the operation port 102. The first cover 21 does not need to be flipped relative to the base 10 to cover the operation port 102 with the second cover 23.

[0081] In one embodiment, please refer to Figure 6 The cover shaft 213 includes a connecting telescopic part 2131 and a retaining shaft 2133. The cover member 211 is provided with a mounting part 2113. The telescopic part 2131 is mounted on the mounting part 2113. The telescopic part 2131 extends in a wave shape and can elastically extend and retract along the axial direction of the retaining shaft 2133, which passes through the mounting part 2113 and enters the first groove 103 or the first shaft hole 104.

[0082] The aforementioned wavy extension telescopic portion 2131 is highly elastic, which can easily improve the stability of the retaining shaft 2133 in the first groove 103 and the first shaft hole 104, thereby improving the stability of the first cover 21 and the second cover 23 in the receiving cavity 101 and in the operation port 102.

[0083] In one embodiment, the first cover 21 and the second cover 23 are configured to lock within the receiving cavity 101 and unlock within the operating port 102. The locked first cover 21 and the second cover 23 facilitate simultaneous movement to ensure the flip cover 20 is stacked within the receiving cavity 101, thereby reducing the space occupied by the flip cover 20 during movement. The first cover 21 and the second cover 23 can be unlocked and move relative to each other at the point where they enter the operating port 102, facilitating the covering of the operating port 102.

[0084] Please see Figure 6 , Figure 7 and Figure 8The second cover 23 includes a main body 231 and a mating part 233. The main body 231 and the mating part 233 are indirectly connected. The second cover 23 also includes a deformable part 232. The deformable part 232 is connected to the main body 231, and the mating part 233 is connected to the deformable part 232. The first cover 21 is provided with a through hole 202. The mating part 233 extends into the through hole 202 and can be stopped by the radial force of the hole wall of the through hole 202, so that the first cover 21 and the second cover 23 are relatively positioned and locked. For example, the mating part 233 is generally cylindrical, and the through hole 202 is a circular hole. When the first cover 21 and the second cover 23 move radially along the through hole 202, the hole wall of the through hole 202 stops the mating part 233 radially, so that the mating part 233 cannot move radially relative to the through hole 202, and thus the second cover 23 cannot move radially relative to the first cover 21 along the through hole 202. Alternatively, the mating part 233 is roughly a square column structure, and the through hole 202 is a square hole. The mating part 233 is stopped by the hole wall of the through hole 202 along the radial direction of the through hole 202, so the second cover 23 cannot move relative to the first cover 21 along the radial direction of the through hole 202.

[0085] The elastic force of the deformable part 232 can drive the mating part 233 to be stably located in the through hole 202. When the deformable part 232 is subjected to an external force greater than the elastic force, it deforms. For example, when the second cover 23 is subjected to a force that separates it from the first cover 21, the deformable part 232 undergoes elastic deformation, and the mating part 233 moves with the deformable part 232 and exits the through hole 202. The first cover 21 and the second cover 23 are unlocked, and the second cover 23 can move relative to the first cover 21, thereby covering more of the operating port 102.

[0086] It is understood that in other embodiments, the deformable part 232, the mating part 233, and the main body 231 are independent structures. For example, the deformable part 232 is a spring, the mating part 233 is slidably connected to the main body 231, and the deformable part 232 abuts against the main body 231 and the mating part 233. The protrusion 123 abuts against the mating part 233, causing the deformable part 232 to deform under force and causing the mating part 233 to exit the through hole 202.

[0087] In one embodiment, the base 10 has a protrusion 123 located at the operation port 102. The through hole 202 passes through the side of the first cover 21 facing the base 10 when it rotates toward the operation port 102.

[0088] When the second cover 23 exits the receiving cavity 101 and rotates into the operating port 102, the protrusion 123 penetrates through the through hole 202 and engages with the side of the first cover 21 facing the seat 10. The protrusion 123 engaged with the through hole 202 can push against the mating part 233. The deformable part 232 is elastically deformed by the force exerted on the mating part 233, causing the mating part 233 to exit the through hole 202. Figure 9 As shown.

[0089] The protrusion 123 engages with the through hole 202, which helps to stabilize the first cover 21 within the operating opening 102. The engagement of the protrusion 123 with the through hole 202 allows the mating part 233 to be pushed out of the through hole 202, thereby unlocking the first cover 21 and the second cover 23. This helps the user save the effort required to push or pull the second cover 23 to cover the operating opening 102, making the cover assembly 100 easier to operate.

[0090] In addition, the protrusion 123 pushes against the mating part 233 only when the second cover 23 rotates into the operating port 102, so that the second cover 23 and the first cover 21 keep moving synchronously before the first cover 21 is stable in the operating port 102, which is beneficial to the stability of the flip cover 20 during the movement.

[0091] In one embodiment, please refer to Figure 6 , Figure 7 and Figure 11 The mating part 233 has a guide part 2331 at one end opposite to the deformation part 232. The guide part 2331 can be a sloping plane or an inclined curved surface. For example, the end of the mating part 233 can be chamfered or rounded, so that the guide part 2331 is located in the through hole 202 and can easily slide along the hole wall of the through hole 202 when subjected to force, thus making it easy for the mating part 233 to exit the through hole 202. The guide part 2331 can easily slide along the hole wall of the through hole 202, reducing the unlocking force of the first cover 21 and the second cover 23, making the cover assembly 100 easy to operate.

[0092] It is understood that in other embodiments, when the first cover 21 rotates into the operating port 102, a portion of the protrusion 123 engages with the through hole 202 and pushes a portion of the mating part 233 out of the through hole 202. The other portion of the mating part 233 is driven out of the through hole 202 by the movement of the second cover 23 relative to the first cover 21. For example, the guide part 2333 slides along the hole wall of the through hole 202, causing the mating part 233 to gradually exit the through hole 202.

[0093] It is understood that in other embodiments, the guide portion 2331 can protrude from the side of the first cover 21 opposite to the deformable portion 232. The mating portion 233 is configured to move toward the protrusion 123 under the action of the first cover 21 moving within the operating port 102, and is pressed by the protrusion 123, causing the deformable portion 232 to elastically deform, so that the guide portion 2331 retracts into the through hole 202. For example, the protrusion 123 is configured as a sidewall of the seat 10 located on the outer periphery of the first groove 103 and within the operating port 102. When the guide portion 2331 exits from the first groove 103, it is squeezed by the sidewall of the operating port 102 and moves into the through hole 202. The guide portion 2331 located in the through hole 202 moves along the hole wall of the through hole 202 under the action of the force on the second cover 23, so that the mating portion 233 exits the through hole 202. The guide portion 2331 protrudes from the side of the first cover 21 opposite to the deformable portion 232 and does not contact the wall of the through hole 202. This reduces the risk of the first cover 21 and the second cover 23 slipping off the wall of the through hole 202 when they move within the receiving cavity 101, thereby improving the locking stability of the first cover 21 and the second cover 23. One end of the guide portion 2331 protruding from the first cover 21 of the mating portion 233 is located within the first groove 103, but is not limited to this. For example, if there is a gap between the first cover 21 and the cavity wall of the receiving cavity 101, the end of the guide portion 2331 of the mating portion 233 can also be located within the gap between the first cover 21 and the cavity wall of the receiving cavity 101. This ensures that the mating portion 233 does not interfere with the seat 10, reduces frictional resistance, and improves the smoothness of movement of the first cover 21 and the second cover 23 within the receiving cavity 101. It is understood that in other embodiments, the end of the guide portion 2331 provided in the mating part 233 may also be located in another groove provided in the seat body 10.

[0094] It is understood that in other embodiments, the guide portion 2331 may also be omitted.

[0095] It is understandable that the protrusion 123 can also be omitted. The deformable part 232 is configured such that when the first cover 21 is positioned within the operating port 102, it elastically deforms under the driving force of the movement of the second cover 23 relative to the first cover 21, causing the mating part 233 to disengage from the through hole 202. When the first cover 21 is positioned relative to the seat 10, the force driving the second cover 23 to move relative to the first cover 21 is greater than the force that causes the mating part 233 to be held in the through hole 202, so that the first cover 21 and the second cover 23 are simultaneously relative to the seat 10. After the second cover 23 is positioned within the operating port 102, a force is applied to the second cover 23, causing the deformable part 232 to deform, thereby causing the mating part 233 to disengage from the through hole 202, and thus causing the second cover 23 to move relative to the first cover 21, simplifying the structure.

[0096] In one embodiment, the first cover 21 is further provided with a second groove 203. The second groove 203 connects to the through hole 202. After the mating part 233 exits the through hole 202, it enters the second groove 203 and slides along the second groove 203, causing the second cover 23 to slide relative to the first cover 21. The second cover 23 and the first cover 21 gradually shift away from each other, thereby gradually increasing the covering area at the operation opening 102. The mating part 233 slides within the second groove 203 without disengaging from it, thus ensuring that the second cover 23 and the first cover 21 remain connected, facilitating the integrity of the flip cover 20. The mating part 233 can both cooperate with the through hole 202 to lock and unlock the first cover 21 and the second cover 23, and cooperate with the second groove 203 to allow the second cover 23 to slide relative to the first cover 21, thus unfolding the flip cover 20. This integrated structure and function simplifies the structure.

[0097] In one embodiment, please refer to Figure 6 and Figure 10 The second cover 23 is provided with an operating part 237. When the first cover 21 and the second cover 23 are stacked in the receiving cavity 101, the operating part 237 is located outside the receiving cavity 101. The operating part 237 facilitates the operator to push and pull the flip cover 20. When the first cover 21 and the second cover 23 are stacked, pulling the operating part 237 will sequentially move the second cover 23 and the first cover 21. When the first cover 21 is removed from the receiving cavity 101, pulling the operating part 237 will move the second cover 23 relative to the first cover 21. The operating part 237 is always located outside the receiving cavity 101, so that the flip cover 20 does not need to have operating parts 237 on the first cover 21 and the second cover 23 respectively, which helps to simplify the structure.

[0098] In one embodiment, please refer to Figure 4 , Figure 11 and Figure 12 When the second cover 23 overlaps with the first cover 21 to cover the operating opening 102, it is located on the side of the first cover 21 facing the base 10. When the second cover 23 is offset relative to the first cover 21, it moves from the inside to the outside of the operating opening 102 relative to the first cover 21, thereby reducing or eliminating the distance between the surfaces of the first cover 21 and the second cover 23 facing the outside of the operating opening 102, for example, the surfaces of the first cover 21 and the second cover 23 facing the outside of the operating opening 102 are flush, but not limited to this.

[0099] The second groove 203 includes a first section 2031 and a second section 2032 arranged in sequence. The second section 2032 is inclined relative to the first section 2031. The mating part 233 moves along the first section 2031 and the second section 2032 in sequence, so that when the second cover 23 slides from the first section 2031 to the second section 2032, it moves towards the side away from the seat 10 when covering the operation opening 102 of the first cover 21, and the second cover 23 unfolds relative to the first cover 21. The mating part 233 moves along the second section 2032 and the first section 2031 in sequence, so that when the second cover 23 covers the operation opening 102 of the first cover 21, it moves towards the side of the seat 10, and then the second cover 23 gradually enters the receiving area 201 of the first cover 21, so as to be stacked with the first cover 21.

[0100] Please see Figure 10 and Figure 12 In one embodiment, the first cover 21 is provided with a first inclined surface 2111, and the second cover 23 is provided with a second inclined surface 2311. The first inclined surface 2111 and the second inclined surface 2311 can slide relative to each other and abut against each other when the first cover 21 and the second cover 23 are unfolded relative to each other. The abutment of the first inclined surface 2111 and the second inclined surface 2311 can improve the overall strength of the flip cover 20 and improve the continuity between the first cover 21 and the second cover 23, thereby improving the sealing performance of the first cover 21 and the second cover 23 in covering the operation opening 102, which is beneficial to improving the protective effect of the flip cover 20 on the interface 400 inside the operation opening 102.

[0101] The first inclined surface 2111 and the second inclined surface 2311 slide relative to each other, which has a guiding effect and helps to improve the stability of the second cover 23 sliding relative to the first cover 21.

[0102] In one embodiment, the first cover 21 further includes an abutment surface 2112. The second cover 23 includes a plurality of abutment portions 235, for example, two. The two abutment portions 235 abut against the abutment surface 2112 when the first cover 21 and the second cover 23 are unfolded relative to each other. The abutment portions 235 abut against the abutment surface 2112, thereby increasing the strength of the first cover 21 and the second cover 23.

[0103] It is understood that in other embodiments, the number of abutting portions 235 may also be one, three, or other quantities. The abutting portions 235 and the abutting surfaces 2112 may also be omitted.

[0104] In one embodiment, such as Figure 6 As shown, the first cover 21 is also provided with a reinforcing part 2114. The reinforcing part 2114 is located at the end of the first cover 21 that is away from the second cover 23 when it is unfolded relative to the second cover 23. The reinforcing part 2114 is spaced apart from the mounting part 2113 so that the abutting part 235 is accommodated between the mounting part 2113 and the reinforcing part 2114.

[0105] Please see Figure 5 and Figure 6 In one embodiment, the base 10 is further provided with a stop 121, which divides the operating part 237 into two areas. The first cover 21 and the second cover 23 are respectively installed in the two areas. The retaining pin 2133 of the first cover 21 rotates around the first shaft hole 104 into the operating opening 102. The stop 121 and the hole wall of the first shaft hole 104 simultaneously stop the movement of the first cover 21. When the first cover 21 covers the operating opening 102, it abuts against the side wall of the operating opening 102 and the stop 121, and the first cover 21 is firmly fixed in the operating opening 102 by the squeezing force or friction.

[0106] It is understood that in other embodiments, the stop portion 121 may also be omitted.

[0107] Please see Figure 10 The second cover 23 is provided with a pin 236. The base 10 is provided with a third groove 105 communicating with the operating port 102 and a second shaft hole 106. The second shaft hole 106 is located at the end of the third groove 105 away from the receiving cavity 101. The end of the third groove 105 facing the receiving cavity 101 forms an opening 1051. The second cover 23 is configured such that when it moves relative to the first cover 21 within the operating port 102, the pin 236 enters the third groove 105 from the opening 1051 and slides along the third groove 105 until it engages with the second shaft hole 106.

[0108] The pin 236 can slide within the third groove 105 to change the area of ​​the second cover 23 covering the operation port 102, and can be engaged in the second shaft hole 106 to stably maintain the entire area of ​​the first cover 21 and the second cover 23 covering the operation port 102.

[0109] The friction or squeezing force between the second cover 23 and the side wall of the operating port 102, or the friction between the pin 236 and the third groove 105, etc., can make the second cover 23 positioned at any position where the pin 236 slides to the third groove 105, thereby achieving the purpose of the second cover 23 and the first cover 21 covering part of the operating port 102.

[0110] The aforementioned flip cover 20, by stacking the first cover 21 and the second cover 23 within the receiving cavity 101, and by staggering or relatively unfolding the first cover 21 and the second cover 23 compared to when the first cover 21 and the second cover 23 are offset, and by reducing the length of the receiving cavity 101 occupied by a single cover structure, reduces the internal space occupied by the receiving cavity 101. This is beneficial for the internal space layout of the device, while ensuring that the second cover 23, stacked or staggered with the first cover 21, covers the operating opening 102. The first cover 21 and the second cover 23 can be at least partially staggered within the operating opening 102, thereby flexibly changing the area of ​​the operating opening 102 covered.

[0111] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
