Description

Technical Field

[0001] This application relates to the field of folding concealed bed technology, and more particularly to an automatic folding concealed bed. Background Technology

[0002] With people's pursuit of quality home life and emphasis on space utilization, the market for foldable concealed beds is rapidly emerging. When not in use, concealed beds can be completely folded away, freeing up valuable floor space so that the room can be used for other purposes, without disrupting the overall design style of the room, maintaining a clean appearance, and adding a modern and stylish touch.

[0003] The process of folding and unfolding a concealed bed typically involves manually lifting one end to fold it up and hide it within a cabinet or wall, achieving the effect of invisibility. However, manual folding can be very strenuous when the bed is heavy, making it inconvenient to use. Electric folding, on the other hand, can cause the bed to jam and become unfoldable in the event of a power outage, thus losing its concealing function and reducing its reliability.

[0004] It is evident that ensuring that a concealed bed can be lifted, folded, and lowered for use even in the event of a power outage is a pressing technical problem that needs to be solved. Utility Model Content

[0005] This application provides an automatic folding concealed bed, which aims to solve the technical problem in the prior art of how to ensure that the concealed bed can be lifted, folded and put down for use even when the power is off.

[0006] This application provides an automatic folding concealed bed, comprising:

[0007] Base assembly;

[0008] A bed frame assembly, which is rotatably connected to the base assembly;

[0009] A motor assembly for driving the bed frame assembly to rotate relative to the base assembly;

[0010] A clutch assembly for engaging or disengaging the motor assembly and the bed frame assembly;

[0011] In the event of a power outage, the clutch assembly separates the motor assembly from the bed frame assembly, allowing the bed frame assembly to rotate freely relative to the base assembly.

[0012] Optionally, the automatic folding concealed bed further includes a connecting assembly, the connecting assembly comprising:

[0013] A connecting shaft, which is fixedly connected to the bed frame assembly;

[0014] A bearing assembly, wherein the outer ring of the bearing assembly is fixedly connected to the base assembly, and the inner ring of the bearing assembly is fixedly connected to the connecting shaft;

[0015] The motor assembly drives the connecting shaft to rotate during operation.

[0016] Optionally, the connecting assembly further includes an adapter, which is fixedly connected to the connecting shaft and detachably connected to the bed frame assembly.

[0017] Optionally, the automatic folding concealed bed further includes a guide assembly, the guide assembly comprising:

[0018] A guide rail component is fixedly installed on the base assembly. The guide rail component is provided with an arc-shaped guide groove, the center of which is located on the rotation center axis of the connecting shaft.

[0019] A guide rod is fixedly connected to the bed frame assembly, and the guide rail guides the guide rod.

[0020] Optionally, the guide assembly further includes a guide roller, which is rotatably mounted on the guide rod and is adapted to the guide groove.

[0021] Optionally, the guide components are disposed on both sides of the bed frame assembly, and the guide components and the connecting components are disposed on both sides of the bed frame assembly.

[0022] Optionally, the automatic folding concealed bed also includes a limit sensing component. After the bed frame assembly rotates to the first stop position or the second stop position, the limit sensing component is triggered, thereby stopping the motor assembly from operating.

[0023] Optionally, the limit sensing component includes:

[0024] A sensor, which is fixedly installed on the bed frame assembly;

[0025] A first sensor is fixedly mounted on the base assembly, and the mounting position of the first sensor corresponds to the first stop position.

[0026] The second sensor is fixedly mounted on the base assembly, and the mounting position of the second sensor is the same as the second stop position;

[0027] Wherein, after the bed frame assembly rotates to the first stop position, the sensing element triggers the first sensor;

[0028] After the bed frame assembly rotates to the second stop position, the sensing element triggers the second sensor.

[0029] Optionally, both the first sensor and the second sensor include a proximity switch.

[0030] The beneficial effects achieved by this application are as follows: During the lifting, folding, or lowering of the automatic folding concealed bed, the clutch assembly is energized, thereby engaging the motor assembly with the bed frame assembly, allowing the motor assembly to drive the bed frame assembly to rotate relative to the base assembly. When a power outage occurs, the clutch assembly loses power, disengaging the motor assembly from the bed frame assembly, allowing the bed frame assembly to rotate freely relative to the base assembly. This enables the automatic folding concealed bed to be manually lifted, folded, or lowered even in the event of a power outage. Thus, when power is available, the motor assembly provides driving force, enabling the automatic folding concealed bed to rotate automatically, thereby lifting, folding, and lowering the bed frame assembly. When the motor assembly cannot operate due to a power outage, the clutch assembly also disengages from the bed frame assembly, preventing the rotation of the bed frame assembly from being obstructed by the motor assembly, allowing the bed frame assembly to rotate freely relative to the base assembly. This enables the automatic folding concealed bed to be manually lifted, folded, or lowered even in the event of a power outage, thus achieving an automatic switch from automatic to manual mode in the event of a power outage. This ensures that the automatic folding concealed bed can still be lifted, folded, and lowered for use even in the event of a power outage. Attached Figure Description

[0045] Please see Figures 1 to 2 In some embodiments of this application, an automatic folding concealed bed 10 is provided, including: a base assembly 20, a bed frame assembly 30, a motor assembly 40, and a clutch assembly 50. The bed frame assembly 30 is rotatably connected to the base assembly 20. The motor assembly 40 drives the bed frame assembly 30 to rotate relative to the base assembly 20. The clutch assembly 50 engages and disengages between the motor assembly 40 and the bed frame assembly 30. Specifically, in the event of a power outage, the clutch assembly 50 disengages the motor assembly 40 from the bed frame assembly 30, allowing the bed frame assembly 30 to rotate freely relative to the base assembly 20.

[0046] During the lifting, folding, or lowering of the automatic folding concealed bed 10, the clutch assembly 50 is energized, which engages the motor assembly 40 with the bed frame assembly 30, allowing the motor assembly 40 to drive the bed frame assembly 30 to rotate relative to the base assembly 20. In the event of a power outage, the clutch assembly 50 loses power, disengaging the motor assembly 40 from the bed frame assembly 30. This allows the bed frame assembly 30 to rotate freely relative to the base assembly 20, enabling the automatic folding concealed bed 10 to be manually lifted, folded, or lowered even in the event of a power outage.

[0047] It can be understood that, when power is available, the motor assembly 40 provides driving force, enabling the automatic folding concealed bed 10 to automatically lift, fold, and lower the bed frame assembly 30 for use. When the motor assembly 40 cannot operate due to power failure, the clutch assembly 50 also disengages due to power failure, thereby separating the motor assembly 40 from the bed frame assembly 30. This prevents the rotation of the bed frame assembly 30 from being blocked by the motor assembly 40, allowing the bed frame assembly 30 to rotate freely relative to the base assembly 20. This allows the automatic folding concealed bed 10 to be manually lifted, folded, or lowered for use even in the event of a power outage, thus automatically switching from automatic to manual mode in the event of a power outage. In this way, the automatic folding concealed bed 10 can still be lifted, folded, and lowered for use even in the event of a power outage.

[0048] Please see Figure 1 and Figure 6 In some embodiments of this application, the automatic folding concealed bed 10 further includes an assist mechanism 90, which includes: a guide slide 91, an abutment slider 92, an abutment fixing block 93, an assist spring 94, a traction member 95, and a rotating member 96. The guide slide 91 is fixedly installed on the base assembly 20. The abutment fixing block 93 is fixedly connected to the guide slide 91, and the abutment slider 92 is slidably connected to the guide slide 91. The assist spring 94 is disposed between the abutment slider 92 and the abutment fixing block 93, with one end of the assist spring 94 abutting against the abutment slider 92 and the other end abutting against the abutment fixing block 93. When the abutment slider 92 slides relative to the guide slide 91, the assist spring 94 undergoes elastic deformation. One end of the traction member 95 is connected to the abutment slider 92, and the other end of the traction member 95 is connected to the rotating member 96. The rotating member 96 is rotatably installed on the base assembly 20, and rotates when the bed frame assembly 30 rotates. The connection point between the traction component 95 and the rotating component 96 is not located at the rotation center of the rotating component 96.

[0049] Understandably, when the automatic folding concealed bed 10 is in manual mode, the weight of the bed frame assembly 30 can make manual lifting and folding or manual directional adjustment of the bed frame assembly 30 for use difficult. The assist mechanism 90 makes lifting, folding, and lowering the bed frame assembly 30 easier and less strenuous.

[0050] Specifically, during the lowering of the bed frame assembly 30, the bed frame assembly 30 is manually pulled, causing it to rotate relative to the base assembly 20, which in turn drives the rotating component 96 to rotate. Since the connection point between the traction component 95 and the rotating component 96 is not located at the rotation center of the rotating component 96, the rotating component 96 pulls the traction component 95 during its rotation. This, in turn, pulls the abutment slider 92, which moves under the guidance of the guide rod 91, causing the assist spring 94 to undergo elastic deformation. Without the assist mechanism 90, it would be quite strenuous to support the bed frame assembly 30 with both hands to ensure its smooth rotation during the lowering process. However, with the assistance mechanism 90, the rotation of the bed frame assembly 30 causes the assist spring 94 to undergo elastic deformation, thus balancing the weight of the bed frame assembly 30 with its elastic force, making the rotation of the bed frame assembly 30 smoother and less strenuous.

[0051] When the bed frame assembly 30 is lowered for use, the gravitational potential energy of the bed frame assembly 30 is converted into the elastic potential energy of the assist spring 94.

[0052] During the process of lifting and folding the bed frame assembly 30, the bed frame assembly 30 is manually lifted, causing it to rotate relative to the base assembly 20. Since the assist spring 94 stores elastic potential energy, the bed frame assembly 30 can be pulled by the elastic force of the assist spring 94 through the traction member 95 during the lifting process, thus making the lifting process of the bed frame assembly 30 easier.

[0053] Please see Figures 2 to 4 In some embodiments of this application, the automatic folding concealed bed 10 further includes a connecting assembly 60, which comprises a connecting shaft 61 and a bearing assembly 62. The connecting shaft 61 is fixedly connected to the bed frame assembly 30. The outer ring of the bearing assembly 62 is fixedly connected to the base assembly 20, and the inner ring of the bearing assembly 62 is fixedly connected to the connecting shaft 61. The motor assembly 40 drives the connecting shaft 61 to rotate during operation.

[0054] With the bearing assembly 62 in place, the structural strength and reliability of the bed frame assembly 30 and the base assembly 20 are ensured, allowing the bed frame assembly 30 and the base assembly 20 to rotate flexibly. In the event of a power outage, even when manually lifting, folding, or lowering the bed frame assembly 30, the process is not too strenuous, making it easier and less strenuous to lift, fold, or lower the bed frame assembly 30.

[0055] Please see Figures 3 to 5 In some embodiments of this application, the connecting component 60 further includes an adapter 63, which is fixedly connected to the connecting shaft 61 and detachably connected to the bed frame assembly 30.

[0056] The connecting shaft 61 is detachably connected to the bed frame assembly 30 via the adapter 63. Thus, when the bed frame assembly 30 needs to be changed, only the bed frame assembly 30 needs to be replaced, without replacing other parts of the automatic folding concealed bed 10. This improves the versatility of the automatic folding concealed bed 10 and allows it to adapt to bed frame assemblies 30 of different sizes.

[0057] Please see Figures 3 to 5 In some embodiments of this application, the automatic folding concealed bed 10 further includes a guide assembly 70, which includes a guide rail 71 and a guide rod 73. The guide rail 71 is fixedly installed on the base assembly 20, and the guide rail 71 is provided with an arc-shaped guide groove 72, the center of which is located on the rotation center axis of the connecting shaft 61. The guide rod 73 is fixedly connected to the bed frame assembly 30, and the guide rail 71 guides the guide rod 73.

[0058] When the bed frame assembly 30 rotates around the central axis of the connecting shaft 61, the force is mainly borne by the bearing assembly 62. During the rotation of the bed frame assembly 30 relative to the base assembly 20, the guide rail 71 guides the guide rod 73, so that the guide rail 71 bears the force of the bed frame assembly 30 in the direction perpendicular to its rotation direction, thereby reducing the force on the bearing assembly 62, reducing the failure rate of the bearing assembly 62, and improving the reliability of the automatic folding concealed bed 10.

[0059] Please see Figures 4 to 5 In some embodiments of this application, the guide assembly 70 further includes a guide roller 74, which is rotatably mounted on the guide rod 73 and is adapted to the guide groove 72.

[0060] During the rotation of the bed frame assembly 30, the guide roller 74 rolls in the guide groove 72 under the drive of the bed frame assembly 30. As a result, when the guide component is subjected to the force from the bed frame assembly 30, the friction force on the inner wall of the guide groove 72 is rolling friction force. On the one hand, this makes the rotation of the bed frame assembly 30 more flexible and reliable, and on the other hand, it reduces the failure rate of the guide assembly 70 and improves the service life of the guide assembly 70.

[0061] In some embodiments of this application, guide components 70 are disposed on both sides of bed frame assembly 30, and guide components 70 and connecting components 60 are disposed on both sides of bed frame assembly 30.

[0062] By providing guide components 70 and connecting components 60 on both sides of the bed frame assembly 30, the force on the bed frame assembly 30 is made more even, thus preventing the bed frame assembly 30 from getting stuck during rotation.

[0063] Please see Figures 4 to 5 In some embodiments of this application, the automatic folding concealed bed 10 also includes a limit sensing component 80. After the bed frame assembly 30 rotates to the first stop position or the second stop position, the limit sensing component 80 is triggered, thereby causing the motor assembly 40 to stop operating.

[0064] When the bed frame assembly 30 rotates to the first stop position or the second stop position, the limit sensor component 80 is triggered, which in turn causes the motor assembly 40 to stop operating, thereby achieving automatic stopping of the motor assembly 40 and preventing the rotation range of the bed frame assembly 30 from exceeding the set range.

[0065] It is understandable that the first stop position corresponds to the position where the bed frame assembly 30 is rotated and lifted and folded into place; the second stop position corresponds to the position where the bed frame assembly 30 is placed stably when it is used in the opposite direction, that is, the position of the bed frame assembly 30 when the bed legs contact the bottom surface.

[0066] In some embodiments of this application, the limit sensing component 80 includes: a sensing element 81, a first sensor 82, and a second sensor 83. The sensing element 81 is fixedly mounted on the bed frame assembly 30. The first sensor 82 is fixedly mounted on the base assembly 20, and its mounting position corresponds to a first stop position. The second sensor 83 is fixedly mounted on the base assembly 20, and its mounting position corresponds to a second stop position. When the bed frame assembly 30 rotates to the first stop position, the sensing element 81 triggers the first sensor 82. When the bed frame assembly 30 rotates to the second stop position, the sensing element 81 triggers the second sensor 83.

[0067] During the rotation of the bed frame assembly 30 driven by the motor assembly 40, the bed frame assembly 30 moves the sensor 81. When the bed frame assembly 30 rotates to the first stop position, the sensor 81 enters the sensing range of the first sensor 82, thereby triggering the first sensor 82. When the first sensor 82 is triggered, the motor assembly 40 stops operating to prevent the bed frame assembly 30 from exceeding its rotation range or to prevent the motor assembly 40 from being overloaded and damaged. Similarly, when the bed frame assembly 30 rotates to the second stop position, the sensor 81 enters the sensing range of the second sensor 83, thereby triggering the second sensor 83. When the second sensor 83 is triggered, the motor assembly 40 stops operating to prevent the bed frame assembly 30 from exceeding its rotation range or to prevent the motor assembly 40 from being overloaded and damaged.

[0068] In some embodiments of this application, both the first sensor 82 and the second sensor 83 include a proximity switch.
