Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to a backrest structure and a bed. Background Technology

[0002] Currently, users often place soft bedding such as blankets and pillows under their lower backs in daily life to achieve a more comfortable leaning posture when reading, using electronic devices, or resting in bed. However, this kind of temporarily stacked bedding structure has poor stability and is prone to sliding or collapsing, resulting in insufficient support. Users need to frequently adjust or rearrange the bedding, leading to a poor user experience. Furthermore, because soft materials are inherently fluffy and easily deformed, they cannot provide even and effective support to the lower back, potentially causing localized pressure concentration, increasing the burden on the spine, and long-term use can easily lead to lower back discomfort or even pain, posing a risk to spinal health.

[0003] To address the aforementioned issues, some beds on the market already employ an integrated adjustable electric or mechanical structure, enabling the backrest to be raised. However, this type of design typically requires integration with a specific bed frame, necessitating the replacement of the entire bed to obtain this function. This not only incurs high costs but also results in the existing bed becoming idle and wasted. Utility Model Content

[0027] Reference Figure 1 , Figure 3The first aspect of this application provides a backrest structure, including a support frame 100, a backrest panel 200, and an adjustment assembly 300. The support frame 100 includes a support rod 110 and a mounting plate 120. The support rod 110 is connected to the mounting plate 120, and a mounting position is formed between the support rod 110 and the mounting plate 120 for accommodating at least a portion of the headboard 500. The backrest panel 200 is hinged to the mounting plate 120. The adjustment assembly 300 is disposed on the mounting plate 120, and the output end of the adjustment assembly 300 is connected to the backrest panel 200 to adjust the angle between the backrest panel 200 and the headboard 500.

[0028] Specifically, at least a portion of the headboard 500 is accommodated in the mounting position formed between the support rod 110 and the mounting plate 120, enabling direct installation with a standard bed frame 700 without integration with a specific bed frame 700. Furthermore, the backrest panel 200 is hinged to the mounting plate 120, and the angle between the backrest panel 200 and the headboard 500 is adjusted via an adjustment component 300 on the mounting plate 120. This allows a standard bed to have an adjustable backrest without replacing the existing bed frame 700, avoiding the need for users to replace the entire bed frame 700 to achieve this feature, reducing operating costs, and preventing existing beds from becoming idle and wasted due to upgrade requirements. Additionally, the backrest structure of this application is simple, easy to install, and improves user comfort while reducing spinal support pressure.

[0029] Reference Figure 1 In some embodiments, a base plate 130 is provided at the bottom of the support rod 110. The base plate 130 is perpendicular to the support rod 110 and is used to connect to the bottom of the headboard 500. Specifically, the support rod 110 is arranged along the height direction of the headboard 500, and the base plate 130 is arranged along the length direction of the headboard 500, so that the headboard 500 can press down on the base plate 130, thereby installing the support rod 110 on the side of the headboard 500. In addition, the base plate 130 and the support rod 110 are fixedly connected as an integral structure, which improves the structural strength of the connection between the base plate 130 and the support rod 110, avoids relative displacement due to force during installation and use, and enhances the stability and load-bearing capacity of the overall structure. In addition, the support rod 110 can be tied to the bed leg with ropes. The bottom plate 130 is positioned at the bottom by the pressure of the headboard 500, and the ropes provide auxiliary reinforcement from the side. Through the synergistic effect of the bottom plate 130 and the ropes, convenient installation is achieved while ensuring connection stability, providing structural support for the stable realization of the backrest 200 angle adjustment function.

[0030] Reference Figure 1 , Figure 2In some embodiments, the support rod 110 includes a first rod 111 and a second rod 112. The first rod 111 is connected to the mounting plate 120. The second rod 112 is provided with a first electric actuator 140, which is connected to a first drive member 150. The first drive member 150 controls the length of the first rod 111 extending into the second rod 112 through the first electric actuator 140 to adjust the height of the support rod 110, thereby adjusting the height of the mounting plate 120 so that the bottom of the mounting plate 120 can be flush with mattresses 600 of different thicknesses, thus adapting to mattresses 600 of different thicknesses. By adjusting the bottom of the mounting plate 120 to be flush with the mattress 600 on the bed frame 700, the height difference between the mounting plate 120 and the mattress 600 due to the difference in mattress thickness is avoided, thereby reducing the gap or protrusion at the connection between the user's back and the mattress 600 and the mounting plate 120 when leaning back, improving the continuity and fit of back support, and further reducing the stress on the spine.

[0031] Specifically, the second rod 112 has a mounting cavity arranged along its axial direction, and the first electric actuator 140 is disposed in the mounting cavity. The first electric actuator 140 has a first thread arranged circumferentially, and the first rod 111 has an adjustment cavity. The side wall of the adjustment cavity has a second thread, and the first thread and the second thread cooperate with each other. The first driving member 150 drives the first electric actuator 140 to rotate, so that the first rod 111 moves along the axial direction of the first electric actuator 140, thereby adjusting the length of the first rod 111 extending into the second rod 112, and thus supporting the height of the rod 110.

[0032] In some embodiments, the first drive element 150 is a motor. The motor controls the length of the first rod 111 extending into the second rod 112, thereby adjusting the first rod 111 and subsequently adjusting the mounting plate 120 up and down. The motor, as a drive source, provides power output, allowing for height adjustment of the mounting plate 120 according to the thickness of different mattresses 600, ensuring the bottom of the mounting plate 120 remains flush with the mattress 600. Furthermore, the motor-driven method eliminates the need for significant manual force, making operation convenient and labor-saving, and suitable for users of different ages. Of course, in actual design, the structure of the first drive element 150 can be customized according to specific needs.

[0033] Reference Figure 1 , Figure 3In some embodiments, the adjustment component 300 includes a second drive member 310 and a second electric actuator 320. The second drive member 310 is connected to the mounting plate 120, and the second electric actuator 320 is connected to the drive end of the second drive member 310. The end of the second electric actuator 320 away from the second drive member 310 is connected to the backrest panel 200. By controlling the extension and retraction of the second electric actuator 320, the second drive member 310 can drive the backrest panel 200 to rise or fall around the hinge point with the mounting plate 120, thereby adjusting the angle between the backrest panel 200 and the headboard 500. This adapts to the user's back support needs in different scenarios such as reading, resting, and watching movies, fully satisfying personalized comfort requirements.

[0034] In some embodiments, the second electric actuator 320 is arranged along the length of the headboard 500, and the second drive unit 310 is a motor. The second electric actuator 320 can convert the power output by the second drive unit 310 into torque to drive the backrest 200 to rotate, reducing power transmission losses and ensuring that the backrest 200 responds more quickly when raised or lowered, further improving the timeliness and stability of angle adjustment. In addition, as a drive source, the motor can adjust the angle between the backrest 200 and the headboard 500 by controlling the extension and retraction stroke of the second electric actuator 320, adapting to different posture needs of users, such as lying down or standing up for reading. The motor drive can ensure uniform speed and stable force during adjustment, avoiding problems such as jamming and sudden angle changes that may occur with manual adjustment or other drive methods, enhancing the user's safety and comfort.

[0035] In some embodiments, the surface of the backrest 200 is covered with a soft material, which improves the fit and softness between the user's back and shoulders and the contact surface of the backrest 200. The deformation properties of the soft material adapt to the different body curves of users, dispersing local contact pressure. Combined with the multi-angle support provided by the adjustment component 300, this further enhances the spinal protection effect. Simultaneously, the frictional properties of the soft material increase the friction between the user's body and the backrest 200, preventing slippage and detachment during adjustments such as raising or lowering the backrest 200 or while leaning against it, thus providing safety for use in different postures.

[0036] Reference Figure 1 , Figure 3In some embodiments, the adjustment assembly 300 further includes a push rod 330, one end of which is hinged to the mounting plate 120, and the other end of which abuts against the backrest panel 200. A second electric actuator 320 is connected to the push rod 330. By pushing the push rod 330 with the second electric actuator 320, the push rod 330 abuts against the backrest panel 200 at different positions, allowing the backrest panel 200 to be raised or lowered at the required angle. The abutment between the push rod 330 and the backrest panel 200 can be adapted to the force point of the backrest panel 200 according to the adjustment requirements, allowing the user to obtain the required support angle.

[0037] Reference Figure 1 , Figure 3 In some embodiments, a roller 331 is provided at the end of the push rod 330 that abuts against the backrest panel 200, so that the sliding friction between the push rod 330 and the backrest panel 200 is converted into rolling friction, reducing frictional resistance and wear loss during relative movement, reducing power consumption during adjustment, reducing the demand on the output power of the second electric push rod 320, and extending the service life of the push rod 330 and the backrest panel 200. In addition, the rolling characteristics of the roller 331 make the push rod 330 more flexible in rotating around the hinge point of the mounting plate 120 and abutting against the backrest panel 200 at different positions, avoiding adjustment jamming or uneven resistance caused by excessive sliding friction, making the lifting and lowering of the backrest panel 200 at different angles more continuous. Combined with the motor's control of the second electric push rod 320, the smoothness and accuracy of angle adjustment are further improved.

[0038] Reference Figure 3 , Figure 4 In some embodiments, a reinforcing plate 210 is provided on the side of the backrest 200 that abuts against the push rod 330. The roller 331 abuts against the reinforcing plate 210, forming a contact between the roller 331 and the reinforcing plate 210. This transfers the contact force between the roller 331 and the backrest 200 to the reinforcing plate 210, preventing direct friction between the roller 331 and the backrest 200 body during rolling adjustment and extending the overall service life of the backrest 200. Furthermore, the reinforcing plate 210 is made of metal, giving it stronger structural strength and wear resistance. The rolling contact with the roller 331 further optimizes the frictional environment between them, converting sliding friction into rolling friction, thus reducing frictional losses during adjustment.

[0039] Reference Figure 3In some embodiments, the adjustment assembly 300 further includes a control panel 340 connected to the second drive component 310. The control panel 340 is used to send commands to control the operation of the second drive component 310. Specifically, the user can control the control panel 340 via a remote control to send adjustment commands, thereby controlling the operating state of the second drive component 310. This drives the second electric actuator 320 to push the push rod 330 to lift, causing the roller 331 at one end of the push rod 330 to move smoothly on the reinforcing plate 210, ultimately completing the lifting or lowering of the backrest 200 at the desired angle. Furthermore, the command transmission from the control panel 340 is instantaneous and precise. Combined with the second drive component 310, it can translate user needs into extension / retraction control of the second electric actuator 320, ensuring that the movement trajectory of the roller 331 on the reinforcing plate 210 more closely matches the expected angle, avoiding over- or under-adjustment, and further guaranteeing the accuracy of the backrest 200 angle adjustment.

[0040] It should be noted that the control panel 340 sending commands to control the operation of the second drive unit 310 is existing technology, and this application has not made any improvements to this part, so its principle and process will not be described in detail.

[0041] In some embodiments, two support rods 110 are provided, spaced apart. The mounting plate 120 is also spaced apart from the support rods 110. The upper end of each support rod 110 is connected to the mounting plate 120 via a connector 400. The headboard 500 is located below the connector 400. The support rods 110 strengthen the connection between the support rods 110 and the mounting plate 120, ensuring that the support rods 110 and the mounting plate 120 maintain a stable relative position during long-term stress and adjustment, preventing loosening or displacement. The symmetrical layout of the two support rods 110 also prevents the backrest 200 from shifting due to unbalanced support, further ensuring adjustment accuracy.

[0042] Reference Figure 1 , Figure 5 In some embodiments, the connector 400 includes a threaded rod 410 and a nut 420. The mounting plate 120 has a first connecting hole, and the support rod 110 has a second connecting hole. The threaded rod 410 passes through the first connecting hole and the second connecting hole sequentially and connects to the nut 420. By adjusting the exposed length of the threaded rod 410 passing between the mounting plate 120 and the support rod 110 and tightening the nut 420, the distance between the support rod 110 and the mounting plate 120 can be adjusted, thereby adjusting the width of the mounting position to accommodate headboards 500 of different widths. Simultaneously, the threaded connection between the threaded rod 410 and the nut 420 forms a lock after the width of the mounting position is adjusted, preventing loosening due to force during use. Combined with the spaced arrangement of the two support rods 110, this provides support for the angle adjustment of the backrest 200, ensuring adjustment accuracy.

[0043] In some embodiments, the distance between the two support rods 110 is greater than the width of the headboard 500. Each support rod 110 is connected to the mounting plate 120 via two connectors 400, and the two connectors 400 on the same support rod 110 are spaced apart vertically. Specifically, along the height direction of the headboard 500, the upper side of the mounting plate 120 is connected to the corresponding support rod 110 via two connectors 400, and the headboard 500 is located below the two connectors 400 during installation. At the same time, the lower side of the mounting plate 120 is connected to the corresponding support rod 110 via two connectors 400, so that the support rod 110 and the mounting plate 120 form a multi-point support structure. With the threaded self-locking characteristics of the threaded rod 410 and the nut 420 in the connector 400, the tilting and shaking of the support rod 110 during use can be prevented.

[0044] In some embodiments, the upper end of the backrest panel 200 is connected to the mounting plate 120 via a hinge structure. This hinge structure allows for a small-clearance rotational fit, enabling the backrest panel 200 to rotate around the hinge axis under the drive of the push rod 330. This prevents wobbling or angular displacement caused by excessive clearance at the hinge joint, further ensuring the positional stability of the backrest panel 200 at different lifting angles. Of course, in actual design, the hinge structure between the backrest panel 200 and the mounting plate 120 can be designed according to specific needs.

[0045] In some embodiments, the push rod 330 and the mounting plate 120 are connected by a hinge structure, which makes the rotation of the push rod 330 around the mounting plate 120 smoother and can accurately transmit the thrust of the second electric push rod 320. Combined with the rolling of the roller 331 at the end of the push rod 330 on the reinforcing plate 210, the mechanical resistance during adjustment is reduced, making the lifting and lowering of the backrest 200 more continuous and smooth. Of course, in actual design, the hinge structure between the push rod 330 and the mounting plate 120 can be designed according to actual needs.

[0046] The second aspect of this application provides a bed that uses the backrest structure of the first aspect of this application, allowing users to obtain a backrest lifting function while retaining the original bed. This reduces the purchase cost for users to obtain the backrest lifting function, avoids the waste of resources caused by replacing the original bed in pursuit of functions, and improves the functionality and economy of the bed.

[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
