Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a step-down locking mechanism and a storage bed. Background Technology

[0002] Storage beds, combining sleeping and storage functions, have become increasingly popular in the market in recent years. Storage beds typically consist of a bed frame and a slatted frame. The bed frame encloses the internal storage space, while the slatted frame is rotatably connected to the bed frame at one end, allowing the storage space to be opened or closed via a top opening. When closed, the slatted frame serves as the bed's support structure; when open, it facilitates the user's access to bedding, clothing, or other items.

[0003] To achieve stable closure and convenient opening of the slatted bed frame, existing storage beds generally incorporate a mechanical locking mechanism between the free end of the slatted bed frame and the bed frame itself. Currently, the mainstream locking method often employs a horizontal sliding operation, such as unlocking by sliding a hook-shaped plate left or right. While this type of mechanism is simple in structure and low in cost, it presents a significant problem of confusion regarding the direction of operation in actual use: users often misjudge the sliding direction due to poor memory or visibility, requiring multiple attempts to unlock successfully. This not only reduces efficiency but also affects the smoothness and intuitiveness of the user experience. Furthermore, frequent misoperations can accelerate wear and tear on the mechanism, even leading to jamming or damage, thus affecting the product's lifespan.

[0004] Therefore, the existing locking mechanism needs to be improved to solve the problem that the operation direction during unlocking is easily confused, resulting in a poor user experience.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a step-down locking mechanism and a storage bed that can solve the problem that the operation direction of the existing locking mechanism is easily confused when unlocking, resulting in a poor user experience.

[0007] To achieve the above objectives, this utility model provides a step-down locking mechanism, comprising:

[0008] The outer casing is used for mounting on the bed frame;

[0009] A rotating hook plate, which is rotatably connected to the outer casing;

[0010] A locking tension spring, which connects the outer casing and the rotating hook plate;

[0011] A step-down assembly is connected to the side of the rotating hook plate opposite to the locking spring and is slidably connected to the outer shell.

[0012] in,

[0013] The rotating hook plate has a locked state in which it rotates forward under the tension of the locking spring to clamp the frame and drives the stepping component to slide upward relative to the outer shell; and an unlocked state in which it rotates in the opposite direction to disengage from the frame when the stepping component is driven to slide downward relative to the outer shell.

[0014] Optionally, the upper part of the rotating hook plate protrudes above the outer casing and forms an opening facing away from the locking spring;

[0015] The middle part of the rotating hook plate is rotatably connected to the outer shell through the hook plate pivot.

[0016] Both the locking spring and the stepping assembly are connected to the lower end of the rotating hook plate.

[0017] Optionally, the step-down component includes:

[0018] An unlocking pedal, the upper end of which extends into the housing and slides vertically with the housing;

[0019] A reversing roller is located between the unlocking pedal and the rotating hook plate, and is positioned higher than the unlocking pedal.

[0020] A flexible connector, one end of which is connected to the rotating hook plate, and the other end of which is connected downward to the unlocking pedal after being reversed by the reversing roller.

[0021] Optionally, the flexible connector is a steel wire rope, a thin steel cable, or a tension spring.

[0022] Optionally, the unlocking pedal includes a vertical part that is slidably connected to the housing at its upper end, and a horizontal part that is fixed to the lower end of the vertical part.

[0023] Optionally, a safety rotating plate is rotatably connected to the lower part of the rotating hook plate;

[0024] The safety rotating plate has a limited rotation state in which it rotates towards the stepping assembly to a horizontal state and approaches the vertical part to restrict the reverse rotation of the rotating hook plate; and a released state in which it rotates away from the stepping assembly to a vertical state and moves away from the vertical part to release the restriction on the reverse rotation of the rotating hook plate.

[0025] Optionally, the safety turntable includes a long side and a short side disposed adjacent to the long side;

[0026] The intersection of the long side and the short side is hinged to the rotating hook plate via a rotating plate shaft;

[0027] When the safety rotating plate is in the limited rotation state, the bottom surface of the rotating hook plate near the stepping component is opposite to the long side surface and magnetically connected.

[0028] When the safety rotating plate is in the unlocked state, the bottom surface of the rotating hook plate away from the stepping component is opposite to the short side and magnetically connected.

[0029] Optionally, the rotating hook plate is made of iron, and magnets are provided on both the long side and the short side.

[0030] Optionally, the safety turntable also includes an outer side disposed opposite to the long side, and the outer side is fixedly provided with a handle.

[0031] On the other hand, a storage bed is provided, comprising:

[0032] A bed frame that encloses a storage space, and a step-down locking mechanism is installed on the inside of the bed frame;

[0033] The slatted frame has one end rotatably connected to the bed frame and the other end provided with a limiting post for engaging with the step-down locking mechanism.

[0034] The beneficial effects of this utility model are as follows: It provides a step-down locking mechanism and a storage bed. In its natural state, the tension of the locking spring acts on the rotating hook plate, causing it to rotate forward around the hinge point of the outer shell. This rotation, on the one hand, causes the upper part of the rotating hook plate to lock the bed frame, thus completing the locking; on the other hand, the rotating hook plate pulls the step-down component connected to it, causing it to slide upward relative to the outer shell and remain in a high position.

[0035] When the user steps down on the pressing component, causing it to overcome the tension of the locking spring and slide downwards relative to the outer casing, the pressing component pulls the lower part of the rotating hook plate, forcing it to rotate in the opposite direction. This rotation causes the upper part of the rotating hook plate to disengage from the frame, thus unlocking the device.

[0036] Stepping down is an intuitive, memory-free, and accident-prone action, greatly enhancing the user experience. Therefore, the step-down locking mechanism and storage bed provided by this utility model can solve the problem of confusion in the operation direction when unlocking existing locking mechanisms, resulting in a poor user experience.

[0057] See Figure 1 This embodiment provides a storage bed, including:

[0058] A bed frame 100 is provided, which encloses a storage space and has a step-down locking mechanism 300 installed on the inner side of the bed frame 100.

[0059] The slatted frame 200 has one end rotatably connected to the bed frame 100, and the other end is provided with a limiting post 200a for engaging with the step-down locking mechanism 300.

[0060] Furthermore, the step-down locking mechanism 300 includes:

[0061] Outer shell 1, mounted on bed frame 100;

[0062] Rotary hook plate 2, which is rotatably connected to the outer shell 1, is used to engage with the limiting post 200a;

[0063] A locking spring 3 connects the outer casing 1 and the rotating hook plate 2;

[0064] The step-down component 4 is connected to the side of the rotating hook plate 2 away from the locking spring 3 and is slidably connected to the outer shell 1.

[0065] Specifically, the upper part of the rotating hook plate 2 protrudes above the outer shell 1 and forms an opening facing away from the locking spring 3 in the slot 201;

[0066] The middle part of the rotating hook plate 2 is rotatably connected to the outer shell 1 through the hook plate rotating shaft 5;

[0067] The locking spring 3 and the stepping assembly 4 are both connected to the lower end of the rotating hook plate 2.

[0068] in,

[0069] The rotating hook plate 2 has a locked state in which it rotates forward under the tension of the locking spring 3 to clamp the frame 200 and drive the stepping component 4 to slide upward relative to the outer shell 1; and an unlocked state in which it rotates in the opposite direction to disengage from the frame 200 when the stepping component 4 is driven to slide downward relative to the outer shell 1.

[0070] In this embodiment, the step-down locking mechanism 300 and storage bed, in their natural state, have the tension of the locking spring 3 acting on the rotating hook plate 2, causing it to rotate forward around the hinge point of the outer shell 1. This rotation, on the one hand, causes the upper part of the rotating hook plate 2 to lock the bed frame 200, thus completing the locking; on the other hand, the rotating hook plate 2 pulls the step-down assembly 4 connected to it, causing it to slide upward relative to the outer shell 1 and remain in a high position.

[0071] When the user steps down on the pressing component 4, causing it to overcome the tension of the locking spring 3 and slide downward relative to the outer shell 1, the pressing component 4 pulls the lower part of the rotating hook plate 2, forcing the rotating hook plate 2 to rotate in the opposite direction. This rotation causes the upper part of the rotating hook plate 2 to disengage from the frame 200, thereby unlocking the device.

[0072] Stepping down is an intuitive, memory-free, and accident-prone action, greatly enhancing the user experience. The step-down locking mechanism 300 and storage bed provided in this embodiment change the unlocking operation from the traditional horizontal flick to a vertical step, perfectly solving the problem of easily confused operating directions. Furthermore, unlocking by foot utilizes the user's own weight, requiring less effort than horizontal flicking or kicking.

[0073] In this embodiment, the step-down component 4 includes:

[0074] Unlocking pedal 401, the upper end of which extends into the housing 1 and is slidably connected to the housing 1 vertically;

[0075] A reversing roller 402 is located between the unlocking pedal 401 and the rotating hook plate 2, and is positioned higher than the unlocking pedal 401.

[0076] The flexible connector 403 is connected at one end to the rotating hook plate 2, and at the other end is connected downward to the unlocking pedal 401 after being reversed by the reversing roller 402.

[0077] Optionally, the flexible connector 403 can be a steel wire rope, a thin steel cable, or a tension spring.

[0078] Furthermore, the unlocking pedal 401 includes a vertical portion 4011 whose upper end is slidably connected to the outer casing 1, and a horizontal portion 4012 fixed to the lower end of the vertical portion 4011.

[0079] When unlocking is required, a downward force is applied to the horizontal portion 4012, which in turn causes the vertical portion 4011 to slide downward. The vertical portion 4011 is connected to the rotating hook plate 2 via a flexible connector 403 and a reversing roller 402, transmitting the downward pulling force as a lateral or diagonal pulling force on the rotating hook plate 2, thereby pulling the rotating hook plate 2 to rotate in the opposite direction to unlock. The cooperation between the flexible connector 403 and the reversing roller 402 allows for a more flexible installation position of the unlocking pedal 401, eliminating the need for strict alignment with the rotating hook plate 2, thus facilitating the overall structural design.

[0080] In this embodiment, a safety rotating plate 6 is rotatably connected to the lower part of the rotating hook plate 2;

[0081] The safety rotating plate 6 has a rotation-limiting state (e.g., it rotates towards the stepping assembly 4 to a horizontal state and approaches the vertical part 4011 to restrict the reverse rotation of the rotating hook plate 2) to a limited state. Figure 1 As shown); and a release state (e.g., rotating away from the stepping assembly 4 to a vertical position and away from the vertical part 4011, thereby releasing the restriction on the reversal of the rotating hook plate 2). Figure 2 (As shown).

[0082] Furthermore, the safety turntable 6 includes a long side 601 and a short side 602 disposed adjacent to the long side 601;

[0083] The intersection of the long side 601 and the short side 602 is hinged to the rotating hook plate 2 via the rotating plate shaft 7.

[0084] When the safety rotating plate 6 is in the limited rotation state, the bottom surface of the rotating hook plate 2 near the stepping component 4 is opposite to the long side surface 601 and magnetically connected.

[0085] When the safety rotating plate 6 is in the unlocked state, the bottom surface of the rotating hook plate 2 away from the stepping component 4 is opposite to the short side 602 and magnetically connected.

[0086] In this embodiment, when the safety rotating plate 6 is in the limited rotation state, the short side 602 is arranged opposite to the vertical part 4011, and the distance between the short side 602 and the vertical part 4011 is small. At this time, if the unlocking pedal 401 is stepped down, before the rotating hook plate 2 has rotated to disengage from the limiting post 200a, the short side 602 will abut against the vertical part 4011, thereby limiting the safety rotating plate 6 from continuing to rotate, and thus preventing the unlocking operation caused by accidental touch.

[0087] When the safety rotating plate 6 is in the unlocked state, the long side 601 and the vertical part 4011 are positioned opposite each other, and the distance between the long side 601 and the vertical part 4011 is relatively large. At this time, if the unlocking pedal 401 is stepped down, the rotating hook plate 2 will have already rotated to disengage from the limiting post 200a before the long side 601 comes into contact with the vertical part 4011, thereby realizing the unlocking operation.

[0088] Optionally, the rotating hook plate 2 is made of iron, and magnets are provided on both the long side 601 and the short side 602. Magnetic attraction ensures the safety rotating plate 6 remains stably in both working positions, preventing accidental changes in state due to vibration or accidental contact, thus ensuring high reliability. Furthermore, the magnetic attraction provides a clear "positioning" feel, resulting in a better user experience.

[0089] In this embodiment, the safety rotating plate 6 further includes an outer side 603 disposed opposite to the long side 601, and the outer side 603 is fixedly provided with a handle portion 604.

[0090] When the safety turn plate 6 is in the vertical unlocked state, the safety turn plate 6 protrudes downward in a large amount, making it easy to see and operate. Therefore, when it is necessary to switch the safety turn plate 6 from the vertical unlocked state to the horizontal limited state, it is only necessary to move the lower part of the outer side 603 of the safety turn plate 6 toward the step-down component 4.

[0091] When the safety turn plate 6 is in the horizontal limited-rotation state, the overall position of the safety turn plate 6 is too high, making it difficult to see and operate. At this time, the handle 604 protrudes vertically downwards, making it easy to see and operate. Therefore, when it is necessary to switch the safety turn plate 6 from the horizontal limited-rotation state to the vertical unlocked state, the handle 604 can be moved away from the step-down component 4 to drive the safety turn plate 6 to rotate away from the step-down component 4 to the vertical unlocked state.

[0092] In summary, the step-locking mechanism 300 and storage bed provided in this embodiment have the following advantages:

[0093] ① By using a step-down unlocking design, the operation direction is changed from horizontal to vertical, which is intuitive and less confusing, thus improving the user experience.

[0094] ② The flexible connector 403 and the reversing roller 402 structure make the installation position of the unlocking pedal 401 flexible and facilitate the overall structural layout.

[0095] ③ A rotatable safety plate 6 is provided, which is magnetically secured to prevent accidental unlocking caused by accidental contact.

[0096] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
