Description

Technical Field

[0001] The present invention relates to the technical field of living furniture, and in particular to an anti-collapse storage bed. Background Art

[0002] As a piece of furniture that combines sleeping and storage functions, a storage bed usually consists of a bed frame, a bed base, and a mattress support (bed board or slat frame):

[0003] The bed frame body encloses a storage cavity with upper and lower openings, and the cavity wall of the storage cavity is provided with a plurality of supporting angle brackets;

[0004] The bed bottom plate is fixed to the bottom of the bed frame body to close the lower end opening of the storage cavity;

[0005] The mattress support is movably mounted on each of the support corners to cover the upper opening of the storage cavity; specifically, the user can lift up the mattress support to store and retrieve items, which is convenient to operate.

[0006] However, the support structure of existing storage beds has obvious defects: the support angle brackets can only provide effective support for the edge area of the mattress support. The middle area of the mattress support lacks upward support force and is prone to collapse and deformation after long-term use, affecting comfort and service life.

[0007] If you add a support structure (such as a support post or bracket) to the center area of the mattress support, you need to secure the support post or bracket to the bed base.

[0008] However, the bottom of the bed frame is usually equipped with support feet to isolate the bed from moisture on the ground, which means that the bed base is usually suspended. As a result, the load-bearing capacity of the bed base (especially the middle area) is limited, and it cannot provide sufficient support for the support columns or brackets. If the support columns or brackets are directly fixed to the bed base, not only will they fail to provide effective support for the mattress support, but they may even cause the bed base to collapse downward, exacerbating structural damage.

[0009] Therefore, how to provide stable support for the middle area of the mattress support without relying on the bed base to bear the weight and prevent it from collapsing has become a technical problem that needs to be solved urgently in this field.

[0010] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Summary of the Invention

[0011] One purpose of the present invention is to provide a collapse-resistant storage bed that can provide stable support for the middle area of the mattress support without relying on the load-bearing capacity of the bed base, thereby solving the problem that the middle area of the mattress support is prone to collapse.

[0012] To achieve the above objectives, the present invention provides an anti-collapse storage bed, comprising:

[0013] A bed frame assembly, wherein the bed frame assembly encloses a storage cavity with an upper end opening, and a plurality of foot slots are provided at the bottom of the storage cavity;

[0014] a mattress support member, the mattress support member being movably mounted on the bed frame assembly and being used to open or close the upper opening of the storage cavity;

[0015] A plurality of movable support feet are provided corresponding to each of the foot slots, and each of the movable support feet is fixedly mounted on the bottom of the mattress support member;

[0016] in,

[0017] When the mattress support member is driven upward to open the upper end opening of the storage cavity, each of the movable supporting feet passes through the corresponding foot slot and moves upward along with the mattress support member;

[0018] When the mattress support member is driven downward to close the upper end opening of the storage cavity, each of the movable supporting feet passes through the corresponding foot slot and moves downward with the mattress support member, providing upward support for the mattress support member.

[0019] Optionally, also include:

[0020] A plurality of sealing components are provided corresponding to each of the foot slots, and the sealing components are installed at the corresponding foot slots, and are used to cover the gap between the foot slots and the movable supporting feet when the mattress support member closes the upper end opening of the storage cavity.

[0021] Optionally, the sealing assembly includes two movable door panel assemblies arranged opposite to each other;

[0022] The two movable door panel assemblies have an open door state in which they are pushed away from each other by the movable supporting feet during the downward movement of the mattress support member to allow the movable supporting feet to pass through; and a closed door state in which they are attached to each other and cover the gap between the foot slot and the movable supporting feet when the mattress support member closes the upper end opening of the storage cavity.

[0023] Optionally, the movable door panel assembly includes:

[0024] A rotating door panel, wherein a side of the rotating door panel close to the movable supporting foot is provided with a door panel profiling groove that fits with one side of the movable supporting foot;

[0025] A door panel torsion spring, wherein the two torsion arms of the door panel torsion spring are respectively connected to a side of the rotating door panel away from the movable supporting foot and an edge position of the foot slot, and are used to drive the rotating door panel to return to the closed state.

[0026] Optionally, the movable door panel assembly further includes:

[0027] An anti-pinch sleeve is sleeved on the outside of the door panel torsion spring and is provided with a strip-shaped avoidance groove for the torsion arm of the door panel torsion spring to extend outward.

[0028] Optionally, a pneumatic connecting rod assembly is also included;

[0029] The mattress support and the bed frame assembly are connected at one end close to the head of the bed by the pneumatic connecting rod assembly;

[0030] The foot groove is in the shape of a long strip extending from the head of the bed to the foot of the bed.

[0031] Optionally, the movable door panel assembly includes:

[0032] A fixed shell, the fixed shell being fixedly arranged at an edge of the foot slot, and a spring cavity being provided inside the fixed shell;

[0033] A sliding gate, one end of which is slidably inserted into the spring cavity, and the other end of which is provided with a gate profiling groove that fits with one side of the movable supporting foot;

[0034] The gate plate compression spring is located in the spring cavity and abuts against the sliding gate plate, and is used to drive the sliding gate plate to slide outward relative to the fixed shell until the gate plate profiling groove is in close contact with the movable supporting foot.

[0035] Optionally, the gate plate profiling groove includes a tapered portion that gradually closes from top to bottom, and a profiling portion located below the tapered portion and in close contact with the movable supporting foot.

[0036] Optionally, also include:

[0037] A plurality of linear drive mechanisms, each of which is mounted and fixed on the bed frame assembly, and a driving end of each linear drive mechanism is connected to the mattress support member, for driving the mattress support member to move up and down relative to the bed frame assembly.

[0038] Optionally, the bed frame assembly includes:

[0039] A bed frame body, the bed frame body enclosing the storage cavity with upper and lower openings;

[0040] a plurality of support angle brackets, each of which is mounted and fixed to a cavity wall of the storage cavity and is used to support the mattress support member when the mattress support member closes the upper end opening of the storage cavity;

[0041] A bed bottom plate, fixed to the bottom of the bed frame body to close the lower opening of the storage cavity and provided with the foot grooves;

[0042] A plurality of fixed support legs, each of which is mounted and fixed to the bottom of the bed frame body so that the bed bottom plate is suspended;

[0043] When the mattress support member closes the upper opening of the storage cavity, the bottom surface of each movable supporting foot is flush with the bottom surface of each fixed supporting foot.

[0044] The beneficial effect of the present invention is that it provides an anti-collapse storage bed. When the mattress support is closed, the movable support feet fixed at the bottom thereof pass through the foot slots at the bottom of the bed frame directly to the ground, forming a rigid support channel that does not pass through the bed bottom board, so that the weight of the mattress support can be directly transferred to the ground through the movable support feet.

[0045] The design of the movable support legs combined with the footwell cleverly avoids the inherent weakness of a suspended bed base, which suffers from its weak load-bearing capacity. The mechanical linkage between the movable support legs and the mattress support maintains the convenience of the storage function (the movable support legs can be raised and lowered synchronously with the mattress) while ensuring that when closed, the movable support legs automatically establish a direct load-bearing system from the ground to the bottom of the mattress. The design of the movable support legs combined with the footwell effectively eliminates the risk of center collapse without increasing the load on the bed base. This optimized mechanical path not only solves the core problem of insufficient support but also has the unexpected added benefit of extending the life of the bed base, as the base now only bears the weight of the stored items, rather than the pressure load from the mattress.

[0046] Therefore, the anti-collapse storage bed provided by the present invention can provide stable support for the middle area of the mattress support without relying on the load-bearing of the bed bottom plate, thereby solving the problem that the middle area of the mattress support is prone to collapse.

For those skilled in the art of the technology to which the present invention belongs, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0068] Through the unique design of movable supporting legs, the present invention transforms the traditional passive support mode that relies on the bed base to indirectly bear the weight into an active support system in which the movable supporting legs directly transmit force. This fundamentally reconstructs the mechanical conduction path of the storage bed. Therefore, it can provide stable support for the middle area of the mattress support without relying on the bed base to bear the weight, thereby solving the problem of the middle area of the mattress support being easily collapsed.

[0069] See also Figure 1 The anti-collapse storage bed provided in this embodiment includes:

[0070] The bed frame assembly 1 is enclosed to form a storage cavity with an upper end open, and the bottom of the storage cavity is provided with a plurality of foot slots 1041;

[0071] A mattress support 2, the mattress support 2 being movably mounted on the bed frame assembly 1 and used to open or close the upper opening of the storage cavity;

[0072] A plurality of movable supporting feet 3 are provided corresponding to each of the foot slots 1041 , and each of the movable supporting feet 3 is fixedly mounted on the bottom of the mattress support member 2 ;

[0073] in,

[0074] When the mattress support member 2 is driven upward to open the upper end opening of the storage cavity, each of the movable supporting feet 3 passes through the corresponding foot slot 1041 and moves upward along with the mattress support member 2;

[0075] When the mattress support 2 is driven downward to close the upper opening of the storage cavity, each of the movable supporting feet 3 passes through the corresponding foot slot 1041 and moves downward with the mattress support 2, providing upward support for the mattress support 2.

[0076] The anti-collapse storage bed provided by the present invention has the following working process:

[0077] (1) Initial state (storage chamber closed):

[0078] The mattress support 2 is placed flat on the bed frame assembly 1, covering the upper opening of the storage cavity.

[0079] The movable support foot 3 extends downward through the foot slot 1041 at the bottom of the bed frame, directly contacting the ground (or floor), and providing vertical upward support force for the mattress support member 2.

[0080] (2) Start the storage process:

[0081] When the user lifts up the mattress support 2 , the movable support foot 3 moves upward synchronously with the mattress support 2 through the foot slot 1041 and leaves the ground.

[0082] At this time, the storage cavity is completely exposed and items can be stored and retrieved freely.

[0083] (3) Close the storage process:

[0084] When the mattress support member 2 is lowered, the movable supporting foot 3 passes through the foot slot 1041 again to contact the ground.

[0085] The movable support legs 3 form a rigid support path from the ground to the bottom of the mattress support member 2 in the closed state.

[0086] Specifically, when the mattress support 2 is closed, the movable support foot 3 fixed at its bottom passes through the foot slot 1041 at the bottom of the bed frame directly to the ground, forming a rigid support channel that does not pass through the bed base 104, so that the weight of the mattress support 2 can be directly transferred to the ground through the movable support foot 3.

[0087] The design of the movable support legs 3 in conjunction with the foot slots 1041 cleverly avoids the inherent weakness of the suspended bed base 104 in its weak load-bearing capacity. Through the mechanical linkage between the movable support legs 3 and the mattress support 2, the convenient storage function is maintained (the movable support legs 3 can be raised and lowered synchronously with the mattress) while ensuring that, when closed, the movable support legs 3 automatically establish a direct load-bearing system from the ground to the bottom of the mattress. The design of the movable support legs 3 in conjunction with the foot slots 1041 effectively eliminates the risk of center collapse without increasing the load on the bed base 104. This optimized mechanical path not only solves the core issue of insufficient support but also unexpectedly provides the added benefit of extending the lifespan of the bed base 104, as the bed base 104 now only bears the weight of the stored items, rather than the pressure load from the mattress.

[0088] Therefore, the anti-collapse storage bed provided by the present invention can provide stable support for the middle area of the mattress support 2 without relying on the load-bearing of the bed base 104, thereby solving the problem that the middle area of the mattress support 2 is prone to collapse.

[0089] Optionally, the bed frame assembly 1 includes:

[0090] The bed frame body 101 is enclosed to form the storage cavity with upper and lower openings;

[0091] A plurality of support angle brackets 103, each of the support angle brackets 103 is mounted and fixed to the cavity wall of the storage cavity, and is used to support the mattress support member 2 when the mattress support member 2 closes the upper end opening of the storage cavity;

[0092] A bed bottom plate 104 , fixed to the bottom of the bed frame body 101 to close the lower opening of the storage cavity and provided with the foot slots 1041 ;

[0093] A plurality of fixed support legs 102, each of the fixed support legs 102 is mounted and fixed to the bottom of the bed frame body 101, so that the bed bottom plate 104 is suspended;

[0094] When the mattress support member 2 closes the upper opening of the storage cavity, the bottom surface of each movable supporting foot 3 is flush with the bottom surface of each fixed supporting foot 102 .

[0095] It is understood that the bed base 104 is suspended to isolate moisture, and the movable support legs 3 are coplanar with the fixed legs to ensure overall balance. Optionally, the fixed support legs 102 and / or the movable support legs 3 are adjustable support legs to facilitate leveling in different on-site environments.

[0096] In this embodiment, the anti-collapse storage bed also includes a plurality of sealing components 4 arranged in one-to-one correspondence with each of the foot grooves 1041. The sealing components 4 are installed at the corresponding foot grooves 1041 and are used to cover the gap between the foot grooves 1041 and the movable supporting feet 3 when the mattress support 2 closes the upper end opening of the storage cavity.

[0097] By adding a sealing assembly 4 corresponding to the foot slot 1041, the gap between the movable support foot 3 and the foot slot 1041 is automatically covered when the mattress support 2 is closed, effectively preventing foreign matter such as dust and insects from entering the storage cavity while improving the overall aesthetics. The linkage design of the sealing assembly 4 ensures the unity of functionality and sealing.

[0098] Furthermore, the sealing assembly 4 includes two opposing movable door panel assemblies 4a. The two movable door panel assemblies 4a can have an open state in which, when the mattress support member 2 moves downward, they are pushed away from each other by the movable support legs 3 to allow the movable support legs 3 to pass through; and a closed state in which, when the mattress support member 2 closes the upper opening of the storage cavity, they abut against each other and cover the gap between the foot slot 1041 and the movable support legs 3.

[0099] Generally, there are two ways to open and close the mattress support 2: one is rotational opening and closing, and the other is vertical opening and closing. In this embodiment, corresponding to the two different opening and closing motions of the mattress support 2, two sealing assemblies 4 are provided, namely rotational opening and closing and sliding opening and closing.

[0100] The following introduces two types of sealing components 4:

[0101] (1) Rotating opening and closing sealing component 4 (suitable for rotating opening and closing mattress support 2)

[0102] The rotary opening and closing sealing assembly 4 is suitable for the rotary opening and closing mattress support 2 (i.e., the mattress support 2 is fulcrum at the head of the bed and is opened or closed by rotating the pneumatic connecting rod assembly 5). Figure 1 The mattress support 2 and the bed frame assembly 1 are connected at one end close to the head of the bed through the pneumatic connecting rod assembly 5; the foot groove 1041 is in the shape of a long strip extending from the head of the bed to the foot of the bed.

[0103] It should be noted that the mattress support 2 and the bed frame assembly 1 are connected at one end near the head of the bed through the pneumatic connecting rod assembly 5 to realize the rotatable openable and closable structure of the mattress support 2, which belongs to the prior art. Pneumatic connecting rod assemblies 5 with different structures can realize the opening and closing states of different movement paths. The specific structure of the pneumatic connecting rod assembly 5 is not the focus of this embodiment, so it will not be elaborated on.

[0104] Furthermore, the movable door panel assembly 4a includes:

[0105] A rotating door panel 401, wherein a door panel profiling groove 4011 is provided on a side of the rotating door panel 401 close to the movable supporting foot 3 and is fitted with a side of the movable supporting foot 3;

[0106] A door panel torsion spring 402, wherein two torsion arms of the door panel torsion spring 402 are respectively connected to a side of the rotating door panel 401 away from the movable support foot 3 and an edge of the foot slot 1041, and are used to drive the rotating door panel 401 to return to the closed state;

[0107] The anti-pinch sleeve 403 is sleeved on the outside of the door panel torsion spring 402 and is provided with a strip-shaped avoidance groove 4031 for the torsion arm of the door panel torsion spring 402 to extend outward.

[0108] Generally, the mattress support 2 connected to the pneumatic connecting rod assembly 5 does not move straight up and down, but rotates open with the head end of the bed as a fulcrum. Therefore, the movable support foot 3 does not move straight up and down, but rotates through the foot slot 1041. The foot slot 1041 is set to be a long strip extending from the head to the foot of the bed instead of a circular structure, in order to leave enough space for the movable support to rotate through, so as to avoid the movable support foot 3 being unable to rotate up and down with the mattress support 2 due to hitting the bottom of the storage cavity.

[0109] Specifically, during the downward rotation of the movable supporting foot 3, the lower end of the movable supporting foot 3 is not directly aligned with the door panel contour groove 4011 at the beginning, but will first abut the area outside the door panel contour groove 4011, so that the two rotating door panels 401 are pressed downward to open. Only when the lower end of the movable supporting foot 3 contacts the bottom surface, the movable supporting foot 3 is just in a vertical state and is exactly aligned with the position of the door panel contour groove 4011. At this time, under the action of the door panel torsion spring 402, the rotating door panel 401 returns to a horizontal state, thereby perfectly covering the gap between the movable supporting foot 3 and the foot groove 1041.

[0110] See also Figure 2 The working process of the rotating opening and closing sealing component 4 is as follows:

[0111] S101: Initial state (mattress support 2 closed, storage cavity sealed)

[0112] (1) The mattress support 2 is placed flat on the bed frame assembly 1, completely covering the storage cavity.

[0113] (2) The movable support foot 3 passes through the long foot slot 1041, and the lower end contacts the ground to provide support.

[0114] (3) The sealing component 4 is in the closed state:

[0115] ① The two rotating door panels 401 remain horizontal and closely fitted under the action of the door panel torsion springs 402.

[0116] ② The door panel contoured groove 4011 of the rotating door panel 401 matches the shape of the movable supporting foot 3 and completely covers the gap of the foot groove 1041.

[0117] ③ The anti-pinch sleeve 403 wraps the door panel torsion spring 402 to prevent foreign objects from interfering or pinching the hands.

[0118] S102: Opening process (mattress support 2 rotates upward, storage cavity exposed)

[0119] (1) The user lifts up the mattress support 2, and the pneumatic connecting rod slowly pushes the mattress support 2 to rotate upward with the head end of the bed as the fulcrum.

[0120] (2) The movable supporting foot 3 moves upward synchronously:

[0121] ① Since the mattress support 2 is opened by rotation, the movement trajectory of the movable support foot 3 is arc-shaped rather than vertically rising.

[0122] ② The long foot slot 1041 (extending along the direction from the head to the foot of the bed) provides sufficient movement space for the movable support leg 3 to avoid getting stuck.

[0123] (3) The sealing component 4 opens upwards:

[0124] When the movable supporting foot 3 moves upward, it pushes the rotating door panel 401 upward and gradually separates from the door panel profiling groove 4011.

[0125] Optionally, in order to prevent the movable supporting foot 3 from getting stuck when moving upward, the movable supporting foot 3 and the door panel contour groove 4011 can be set to a gradually expanding conical structure that gradually expands from top to bottom. When the movable supporting foot 3 moves upward, the gradually expanding conical structure can automatically push the rotating panel door diagonally upward, so that the rotating panel door rotates upward and opens.

[0126] (4) When the mattress support 2 is fully opened, the storage cavity is fully exposed and the user can store and retrieve items.

[0127] S103: Closing process (mattress support 2 rotates downward, storage cavity sealed)

[0128] (1) The user lowers the mattress support 2, and the pneumatic connecting rod assembly 5 controls its slow closing.

[0129] (2) The movable supporting foot 3 moves downward:

[0130] Since the mattress support 2 is rotated and closed, the movement trajectory of the movable support foot 3 is still arc-shaped, first contacting the rotating door panel 401 obliquely, and then gradually falling vertically to the ground.

[0131] (3) Dynamic adjustment of sealing component 4:

[0132] ① Initial contact stage: The lower end of the movable supporting foot 3 first contacts the non-profiling area of the rotating door panel 401 (i.e., the door panel surface, not the profiling groove), applying downward pressure.

[0133] ② The door panel is forced to open: Under the pressure of the movable support foot 3, the two rotating door panels 401 rotate downward (overcoming the elastic force of the door panel torsion spring 402), forming an open door state, allowing the support foot to pass through.

[0134] ③Supporting foot landing stage: When the movable supporting foot 3 lands completely vertically, its position is exactly aligned with the door panel profiling groove 4011.

[0135] (4) Automatic sealing:

[0136] The door panel torsion spring 402 pushes the rotating door panel 401 to return to its original position, so that the contoured groove is in close contact with the movable supporting foot 3 and completely covers the gap of the foot groove 1041 .

[0137] The anti-pinch sleeve 403 ensures smooth movement of the torsion spring to avoid pinching or jamming.

[0138] The mattress support 2 completely closes the upper opening of the storage cavity, the storage cavity returns to a sealed state, and the movable support legs 3 provide the mattress support 2 with rigid support directly to the ground.

[0139] (2) Sliding opening and closing sealing component 4 (suitable for vertically opening and closing mattress support 2)

[0140] Optionally, the vertical up and down movement of the mattress support 2 is achieved by a linear drive mechanism. For example, the anti-collapse storage bed further includes a plurality of linear drive mechanisms, each of which is mounted and fixed on the bed frame assembly 1, and the driving end of each linear drive mechanism is connected to the mattress support 2, for driving the mattress support 2 to move up and down relative to the bed frame assembly 1.

[0141] At this time, see Figure 3 and Figure 4 , the movable door panel assembly 4a includes:

[0142] A fixed housing 404, wherein the fixed housing 404 is fixedly mounted at the edge of the foot slot 1041, and a spring chamber is provided inside the fixed housing 404;

[0143] A sliding gate 405, one end of which is slidably inserted into the spring cavity, and the other end of which is provided with a gate profiling groove 4051 that fits with one side of the movable support foot 3;

[0144] The gate plate compression spring 406 is located in the spring cavity and abuts against the sliding gate plate 405 , and is used to drive the sliding gate plate 405 to slide outward relative to the fixed housing 404 until the gate plate profiling groove 4051 is in close contact with the movable supporting foot 3 .

[0145] Furthermore, the gate plate profiling groove 4051 includes a tapered portion 4051a that gradually closes from top to bottom, and a profiling portion 4051b located below the tapered portion 4051a and in close contact with the movable supporting foot 3.

[0146] The sliding opening and closing sealing component 4 has the following working process:

[0147] S201: Initial closed state

[0148] When the mattress support 2 descends, the movable support foot 3 passes vertically through the foot slot 1041 and lands on the ground. The sliding gate 405 is fully extended under the action of the compression spring, and the contoured portion 4051b fits tightly against the support foot to achieve all-round seamless sealing.

[0149] S202: Opening process

[0150] After the linear drive mechanism is started, the mattress support 2 rises vertically, and the storage space is now completely exposed and available for use. Simultaneously, the movable support foot 3 gradually separates from the contoured portion 4051b upward.

[0151] S203: Closing process

[0152] When the mattress support 2 descends, the movable supporting foot 3 is automatically centered through the tapered conical portion 4051a of the gate (the tapered conical portion 4051a acts as an inclined guide). Finally, when the supporting foot is completely on the ground, the contoured portion 4051b is always in close contact with the outer wall of the movable supporting foot 3 under the pushing action of the gate compression spring 406, forming a long-lasting and stable closed state.

[0153] It is understood that the aforementioned sliding opening and closing sealing assembly 4 can also be applied to scenarios where the mattress support 2 is rotated to open and close. Specifically, when the mattress support 2 rotates downward, the movable support foot 3 first enters between the two gate plate profiling grooves 4051 in an inclined state. As the mattress support 2 gradually rotates downward, the depth of the movable support foot 3 inserted between the two gate plate profiling grooves 4051 gradually deepens, and then pushes the two sliding gates 405 outward. Finally, when the mattress support 2 rotates to a horizontal position, the movable support foot 3 is exactly in a vertical position, and the gate plate profiling groove 4051 is closely attached to the outer wall of the movable support foot 3.

[0154] It should be noted that the linear drive mechanism mentioned in the present invention may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a motor-screw linear module, and the rotary drive mechanism mentioned in the present invention may be a brushed motor, a brushless motor, or a rotary cylinder. The present invention does not limit the specific structural forms of the linear drive mechanism and the rotary drive mechanism.

[0155] In summary, the anti-collapse storage bed provided in this embodiment has the following advantages:

[0156] ① Reconstruction of the active support system: Through the direct force transmission design of the movable support feet 3, a rigid support path is established from the ground to the mattress support 2, which completely solves the problem of center collapse of traditional storage beds.

[0157] ② Mechanical path optimization: The movable supporting feet 3 cooperate with the foot slots 1041 to form an independent load-bearing system, so that the bed base 104 only bears the weight of the stored items, significantly extending the service life of the bed base 104.

[0158] ③ Dynamic sealing protection: The sealing component 4 automatically opens and closes with the movement of the movable support foot 3, effectively preventing dust / insects from entering the storage cavity, taking into account both functionality and aesthetics.

[0159] ④Dual-mode adaptability: The sealing component 4 is designed for rotational / vertical opening and closing modes respectively to ensure seamless sealing and smooth linkage under different movement forms.

[0160] ⑤Anti-pinch safety design: Optimized details such as the anti-pinch sleeve 403 and the tapered tapered structure avoid the risk of mechanical parts being pinched and improve safety in use.

[0161] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
