Description

Technical Field

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

[0002] A storage bed, a type of home furnishing product that combines sleeping and storage functions, typically consists of a bed frame and a slatted frame. The bed frame encloses and forms a storage space with an opening at the top, while the slatted frame is hinged to the bed frame at the head end, forming an opening mechanism that can rotate around the hinge axis to cover or open the storage space. Users can easily access items in the storage space underneath by lifting the foot end of the bed and rotating the slatted frame around the hinge axis.

[0003] To ensure safety and prevent accidental opening of the storage bed frame due to misoperation or unexpected force, some storage beds are equipped with a locking mechanism at the foot of the bed. This locking mechanism is typically installed inside the bed frame and uses a mechanical structure such as a pin, latch, or knob to lock the foot of the storage bed frame, keeping it closed when not in use. Users must first unlock the locking mechanism to release the constraint on the storage bed frame before lifting it to open the storage space.

[0004] However, the locking mechanism is usually located on the side or low of the bed frame, requiring users to bend over or squat to locate it. Furthermore, the locking mechanism is often in a blind spot, making it difficult to observe directly and hindering unlocking operations (such as finding the unlock button, moving the latch, or rotating the knob). This results in a poor user experience, especially for those with mobility issues or in poor lighting conditions.

[0005] This inconvenience reduces the ease and efficiency of using the storage bed. Therefore, it is necessary to improve the existing locking mechanism to solve the problem of its inconvenient unlocking operation.

[0006] 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

[0007] One objective of this invention is to provide an electrically controlled locking mechanism and storage bed that can effectively solve the problem of inconvenient unlocking operation of existing locking mechanisms, resulting in a poor user experience.

[0008] To achieve the above objectives, this utility model provides an electrically controlled locking mechanism, comprising:

[0009] Locking mechanism housing for mounting on the bed frame;

[0010] The hook plate assembly is rotatably mounted on the housing of the locking mechanism and is used to engage the frame;

[0011] A tension spring is located on one side of the hook plate assembly and connects the hook plate assembly to the locking mechanism housing;

[0012] An electromagnetic actuator is located on the other side of the hook plate assembly and is disposed at a distance from the hook plate assembly.

[0013] The controller is communicatively connected to the electromagnetic actuator and is used to control the power supply to and from the electromagnetic actuator.

[0014] in,

[0015] The hook plate assembly has a snap-fit ​​state where it is pulled forward by the tension of the tension spring and engages with the frame; and an unlocked state where it is pulled backward by the magnetic attraction of the electromagnetic actuator and disengages from the frame.

[0016] Optionally, the hook plate assembly includes:

[0017] A rotating hook plate, the upper end of which protrudes above the locking mechanism housing and has a slot with an opening facing away from the tension spring; the middle part of the rotating hook plate is rotatably connected to the locking mechanism housing via a rotating shaft;

[0018] A magnetic attraction unit is connected to the lower end of the rotating hook plate. When the electromagnetic actuator is energized, the magnetic attraction unit is used to drive the rotating hook plate to reverse.

[0019] Optionally, the magnetic attraction unit includes:

[0020] A rotating connecting plate, the middle part of which is hinged to the lower end of the rotating hook plate;

[0021] An armature is attached to one end of the rotating connecting plate near the electromagnetic actuator.

[0022] Optionally, the tension spring is connected to the end of the rotating connecting plate away from the electromagnetic actuator, and is used to apply tension to the rotating connecting plate so that when the electromagnetic actuator is de-energized, the armature is held in a position that is spaced apart from the electromagnetic actuator.

[0023] Optionally, the electromagnetic actuator is an electromagnetic chuck.

[0024] Optionally, the controller includes at least one of the following: a remote control wirelessly connected to the electromagnetic actuator, a control panel wiredly connected to the electromagnetic actuator, and a mobile terminal wirelessly connected to the electromagnetic actuator and equipped with a specified APP.

[0025] Optionally, the controller has a built-in microphone for receiving voice commands.

[0026] Optional, also includes:

[0027] A limiting post is installed on the housing of the locking mechanism, and the limiting post and the tension spring are located on the same side of the hook plate assembly. The limiting post is used to abut against the hook plate assembly when the tension spring drives the hook plate assembly to rotate forward to the locking state, so as to limit the hook plate assembly from continuing to rotate forward.

[0028] Optionally, the limiting post is threadedly connected to the housing of the locking mechanism, making the distance between the limiting post and the hook plate assembly adjustable.

[0029] On the other hand, a storage bed is provided, comprising:

[0030] A bed frame, wherein any of the aforementioned electrically controlled locking mechanisms are installed on the bed frame;

[0031] The slatted frame has one end rotatably connected to the bed frame and the other end provided with a locking post for engaging with the electrically controlled locking mechanism.

[0032] The beneficial effects of this utility model are as follows: It provides an electrically controlled locking mechanism and a storage bed. S10: Snap-fit ​​(locked) state: Under normal conditions (i.e., when the electromagnetic actuator is de-energized), the tension spring continuously applies tension to the hook plate assembly. This tension drives the hook plate assembly to rotate forward around its pivot point until its snap-fit ​​part is firmly snapped into the frame (usually a snap-fit ​​post on the frame). At this time, the end of the frame is locked and cannot be lifted, and the storage bed is in a closed state.

[0033] S20: Unlocking Process: When the user needs to open the storage bed, the controller sends a command to the electromagnetic actuator, energizing it. The energized actuator generates a strong electromagnetic force. This force acts on the hook plate assembly located opposite it. This magnetic force overcomes the tension spring applied to the hook plate assembly, causing it to rotate in the opposite direction, disengaging its locking part from the frame, thus entering the unlocked state. At this point, the user can lift the foot of the bed frame to open the storage space.

[0034] During the above process, users do not need to bend over or squat down to find the mechanical lock. They can remotely unlock the lock using the controller. The operation is simple and labor-saving, greatly improving the user experience. Attached Figure Description

[0055] This utility model provides an electrically controlled locking mechanism and a storage bed, which can effectively solve the problem that the unlocking operation of existing locking mechanisms is inconvenient, resulting in a poor user experience.

[0056] See Figure 1 This embodiment provides a storage bed, including:

[0057] A bed frame 100, on which an electrically controlled locking mechanism 300 is installed;

[0058] The slatted frame 200 has one end rotatably connected to the bed frame 100, and the other end is provided with a locking post 200a for engaging with the electronically controlled locking mechanism 300.

[0059] Specifically, see Figure 2 and Figure 3 The electronically controlled locking mechanism 300 includes:

[0060] Locking mechanism housing 1, for mounting on bed frame 100;

[0061] Hook plate assembly 2 is rotatably mounted on the locking mechanism housing 1 and is used to engage the frame 200;

[0062] A tension spring 3 is located on one side of the hook plate assembly 2 and connects the hook plate assembly 2 to the locking mechanism housing 1;

[0063] Electromagnetic actuator 4 is located on the other side of hook plate assembly 2 and is disposed at a distance from hook plate assembly 2;

[0064] The controller is communicatively connected to the electromagnetic actuator 4 and is used to control the power supply to and from the electromagnetic actuator 4.

[0065] in,

[0066] The hook plate assembly 2 is subjected to the tension of the tension spring 3 and rotates forward to a snap-fit ​​state with the frame 200 (e.g., Figure 2 As shown); and having an unlocked state where it is magnetically attracted by the electromagnetic actuator 4 and rotates in the opposite direction to disengage from the frame 200 (as shown). Figure 3 (As shown).

[0067] In this embodiment, the electromagnetic actuator 4 is a device such as an electromagnetic chuck that generates a magnetic field when energized and the magnetic field disappears when the power is turned off.

[0068] The working process of the electrically controlled locking mechanism 300 and the storage bed provided in this embodiment is as follows:

[0069] S10: Locked-in state: Under normal conditions (i.e., when the electromagnetic actuator 4 is de-energized), the tension spring 3 continuously applies tension to the hook plate assembly 2. This tension drives the hook plate assembly 2 to rotate forward about its pivot point until its locking part is firmly locked into the slat frame 200 (usually the locking post 200a on the slat frame 200). At this time, the tail end of the slat frame 200 is locked and cannot be lifted, and the storage bed is in the closed state.

[0070] S20: Unlocking Process: When the user needs to open the storage bed, the controller sends a command to the electromagnetic actuator 4 to energize it. The energized electromagnetic actuator 4 generates a strong electromagnetic attraction. This attraction acts on the hook plate assembly 2 located opposite it. This magnetic attraction overcomes the tension exerted on the hook plate assembly 2 by the tension spring 3, causing the hook plate assembly 2 to rotate in the opposite direction, disengaging its locking part from the slat frame 200, thus entering the unlocked state. At this time, the user can lift the foot of the bed of the slat frame 200 to open the storage space.

[0071] During the above process, users do not need to bend over or squat down to find the mechanical lock. They can remotely unlock the lock using a remote control, mobile APP, or control panel. The operation is simple and labor-saving, greatly improving the user experience.

[0072] In this embodiment, the hook plate assembly 2 includes:

[0073] A rotating hook plate 201 is provided, the upper end of which protrudes above the locking mechanism housing 1 and has a slot 2011 with an opening facing away from the tension spring 3; the middle part of the rotating hook plate 201 is rotatably connected to the locking mechanism housing 1 through a rotating shaft 2012.

[0074] The magnetic attraction unit 202 is connected to the lower end of the rotating hook plate 201. When the electromagnetic actuator 4 is energized, the magnetic attraction of the electromagnetic actuator 4 causes the rotating hook plate 201 to reverse.

[0075] Furthermore, the magnetic attraction unit 202 includes:

[0076] A rotating connecting plate 2021, the middle part of which is hinged to the lower end of the rotating hook plate 201;

[0077] An armature 2022 is connected to one end of the rotating connecting plate 2021 near the electromagnetic actuator 4.

[0078] When the electromagnetic actuator 4 is energized, it directly attracts the magnetic attraction unit 202, thereby providing a reverse rotational force to the lower end of the rotating hook plate 201 to overcome the tension force exerted by the tension spring 3 on the upper end of the rotating hook plate 201, thus unlocking the device. Specifically, the working process of the magnetic attraction unit 202 is as follows:

[0079] (1) Initial state: The rotating connecting plate 2021 is connected to the lower end of the rotating hook plate 201 through the hinge point in its middle, forming a rotating pair that can rotate relative to each other. The armature 2022 is fixed to the end of the rotating connecting plate 2021 near the electromagnetic actuator 4.

[0080] (2) Composite motion during unlocking: When the electromagnetic actuator 4 is energized and generates a magnetic force, it will attract the armature 2022. This attraction force can be decomposed into motion in two directions:

[0081] Lateral movement: The attraction forces the armature 2022 and the rotating connecting plate 2021 to move laterally toward the electromagnetic actuator 4.

[0082] Adaptive Rotation: Since the rotating connecting plate 2021 and the rotating hook plate 201 are hinged rather than rigidly fixed, the rotating connecting plate 2021 can undergo a slight adaptive rotation around its central hinge point while moving laterally. This rotation ensures that regardless of the angle of the rotating hook plate 201, the armature 2022 at the front end of the rotating connecting plate 2021 can automatically adjust its posture so that its adsorption surface always remains parallel and directly opposite the surface of the electromagnetic actuator 4, thereby achieving efficient and stable magnetic attraction.

[0083] (3) Linkage unlocking: The lateral movement and adaptive rotation of the rotating connecting plate 2021 are transmitted to the rotating hook plate 201 through the hinge point in its middle, which is converted into a clear torque that forces the rotating hook plate 201 to rotate in the opposite direction around its own rotation axis 2012, thereby overcoming the tension of the tension spring 3 and realizing unlocking.

[0084] Understandably, the rotating connecting plate 2021 provides degree-of-freedom compensation. By introducing a rotational degree of freedom, it solves the motion interference problem between linear magnetic attraction and rotational unlocking motion. The rotatable design of the rotating connecting plate 2021 allows the magnetic attraction unit 202 (armature 2022) to adaptively adjust its angle during movement, ensuring full contact with the electromagnetic actuator 4's attraction surface. This avoids problems such as edge contact or inclined attraction between the armature 2022 and the electromagnetic actuator 4 due to machining, installation errors, or deviations in the motion trajectory, greatly reducing the risk of jamming and making the attraction action smooth and reliable.

[0085] In this embodiment, the tension spring 3 is connected to the end of the rotating connecting plate 2021 away from the electromagnetic actuator 4, and is used to apply tension to the rotating connecting plate 2021 so that when the electromagnetic actuator 4 is de-energized, the armature 2022 remains at a position that is spaced apart from the electromagnetic actuator 4.

[0086] Without the tension of spring 3, relying solely on the hinge between the lower end of the rotating connecting plate 2021 and the rotating hook plate 201, the entire rotating connecting plate 2021 (along with the armature 2022) will naturally droop like a pendulum under its own weight, eventually rotating to a vertically suspended state with the armature 2022 facing downwards. Once in this state, even if the electromagnetic actuator 4 is energized again, the horizontal magnetic attraction it generates will be completely misaligned with the vertical armature 2022, making it unable to effectively attract the armature 2022, resulting in complete failure of the mechanism and inability to unlock.

[0087] A lateral tension is applied by connecting the tension spring 3 to the end of the rotating connecting plate 2021 away from the electromagnetic actuator 4. This tension generates a torque that continuously counteracts the clockwise gravitational torque generated by the weight of the rotating connecting plate 2021 and the armature 2022, causing them to droop. In the normal state where the electromagnetic actuator 4 is de-energized, the torque of the tension spring 3 balances the gravitational torque of the moving parts, thus forcibly maintaining the rotating connecting plate 2021 in a roughly horizontal position. This ensures that the armature 2022, fixed to its front end, is always held in an accurate position, directly opposite and at a certain distance from the horizontally mounted electromagnetic actuator 4, forming a stable "standby" state.

[0088] Because this "standby" position is precisely maintained, once the electromagnetic actuator 4 is powered on, its magnetic lines of force can act vertically and efficiently on the armature 2022 directly opposite, generating the maximum magnetic attraction force and ensuring that every unlocking action can be reliably completed.

[0089] In this embodiment, the controller includes at least one of the following: a remote control wirelessly connected to the electromagnetic actuator 4; a control panel (installed on the side of the headboard or bed frame 100) wiredly connected to the electromagnetic actuator 4; and a mobile terminal wirelessly connected to the electromagnetic actuator 4 and equipped with a specified APP.

[0090] Users can control the device wirelessly via a remote control, wired via a control panel on the bed, or wirelessly via a smartphone or other mobile terminal with a designated app installed, sending power signals to the electromagnetic actuator 4. This variety of control methods caters to the usage habits and needs of different user groups, greatly enhancing the product's versatility and user experience. For example, younger users may use a mobile app, while older users may prefer a simpler remote control.

[0091] Optionally, the controller has a built-in microphone to receive user voice commands (such as "open the bed box"), which are then recognized by the internal circuitry and used to control the electromagnetic actuator 4. Voice control enables the unlocking process to be extremely convenient, requiring only voice commands, and is highly intelligent, making it particularly suitable for smart home scenarios or situations where users have limited hands.

[0092] In this embodiment, the electrically controlled locking mechanism 300 further includes a limiting post 5. The limiting post 5 is installed on the locking mechanism housing 1, and the limiting post 5 and the tension spring 3 are located on the same side of the hook plate assembly 2. When the tension spring 3 drives the hook plate assembly 2 to rotate forward to the engaging state, the limiting post 5 abuts against the hook plate assembly 2 to limit the hook plate assembly 2 from continuing to rotate forward.

[0093] The limiting post 5 is positioned on the forward rotation path of the hook plate assembly 2. When the tension spring 3 pulls the hook plate assembly 2 to the locking state, the hook plate assembly 2 (or a part thereof) will abut against the limiting post 5, preventing it from continuing to rotate. The limiting post 5 provides precise mechanical limiting, ensuring that the position of the hook plate assembly 2 (rotating hook plate 201) remains consistent and accurate in each locked state, thereby guaranteeing the reliability and consistency of the locking and preventing damage to the mechanism or loose locking due to over-rotation.

[0094] Furthermore, the limiting post 5 is threadedly connected to the locking mechanism housing 1, making the distance between the limiting post 5 and the hook plate assembly 2 adjustable. By rotating the limiting post 5, the depth to which it is screwed into the locking mechanism housing 1 can be adjusted, thereby changing the relative distance between its end and the hook plate assembly 2. The screw connection provides adjustability, allowing for fine-tuning of the final position of the rotating hook plate 201 in the locked state to compensate for manufacturing and installation errors of different bed frames 100 and slatted frame 200, ensuring the accuracy and reliability of the snap-fit, and enhancing the product's adaptability and fault tolerance.

[0095] In summary, the electrically controlled locking mechanism 300 and storage bed provided in this embodiment have the following advantages:

[0096] ①The remote electronic unlocking of the storage bed locking mechanism is achieved through the coordinated control of the electromagnetic actuator 4 and the tension spring 3, making the operation convenient and labor-saving.

[0097] ② By setting up an adaptively rotatable magnetic suction unit 202, the interference problem between linear magnetic suction and rotary unlocking motion is solved, ensuring smooth and reliable suction action.

[0098] ③ A lateral tension is applied to the rotating connecting plate 2021 by the tension spring 3, so that the armature 2022 remains in the standby position facing the electromagnetic actuator 4 when the power is off, ensuring the reliability of the unlocking action.

[0099] ④ By setting an adjustable threaded limit post 5, the snap-fit ​​position of the hook plate assembly 2 is precisely controlled, which improves the accuracy of locking and adaptability to different installation errors.

[0100] 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.
