A mattress support is then installed between the structure formed by the bed rails, footrests and bed screens. The mattress support is connected to the bed rails, footrests and bed screens on all sides. A mattress can be placed on the mattress support, but the thickness of mattresses is not consistent nowadays. In order to make the mattress fully support the person and avoid direct contact between the lower side of the person's legs and the bed rails and footrests, in order to improve the comfort of sitting on the edge of the bed, the position of the mattress support needs to be adjusted to a suitable height so that the upper edge of the mattress is higher than the upper edge of the bed rails and footrests by a certain distance.

[0003] Under the existing technology, the mattress support part is installed on the L-shaped corner brackets on the bed frame, the foot of the bed and the side of the bed screen. A mattress is placed on the mattress support part, and a mattress sheet is wrapped around the outer side of the mattress. The mattress sheet needs to be replaced and cleaned regularly. Since the lower bottom surface of an ordinary mattress is lower than the upper edge of the bed frame and the foot of the bed, if the lower mattress sheet is taken out, the entire mattress needs to be manually removed from the mattress support part, and then the mattress sheet can be removed from around the mattress. After cleaning and drying the mattress sheet, it needs to be wrapped on the mattress, and then the mattress is placed on the mattress support part. The whole replacement process is relatively laborious. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0027] Under the existing technology, the corner brackets are installed on the bed body by fastening with screws, which causes the bottom surface of the mattress to be lower than the upper edges of the bed frame and the foot of the bed. To replace the fitted sheet, the mattress needs to be removed, and then the mattress can be put on the mattress after the fitted sheet is completed. The replacement process is relatively laborious. In addition, the mattress and the mattress support part need to be taken out for each adjustment, and then the corner brackets need to be removed manually with a screwdriver, and the height needs to be readjusted before installation. There are multiple sets of corner brackets, and disassembly and assembly are relatively time-consuming. At the same time, since the screw holes for fixing the corner brackets on the bed body are vertically distributed at equal intervals, the corner brackets can only provide a few sets of fixed heights for the mattress support part, and cannot adapt to mattresses of different thicknesses.

[0028] In order to solve the above problems, Figures 1 to 7 As shown, the utility model provides a height-adjustable bed, which includes a bed body 1, a lifting component 2, and a mattress support part. The bed body 1 includes a bed frame 11, a bed foot 12 and a bed screen 13. The bed foot 12 and the bed screen 13 are placed in parallel, and the bed foot 12 and the bed screen 13 are connected by the bed frame 11. The bed frame 11, the bed foot 12 and the bed screen 13 form an installation area 3. The installation area 3 is rectangular and can adapt to a rectangular mattress and a mattress support part. The bed frame 11, the bed foot 12 and the bed screen 13 are located on one side of the installation area 3 as an installation surface 14, and the lifting component 2 is fixed on the installation surface 14. The lifting component 2 of the utility model includes eight groups, and two groups of lifting components 2 are installed on the installation surface 14 on each side. The mattress support part is overlapped on the lifting component 2, so that the mattress support part can move stably in the height direction without shaking. The mattress support part is usually a slat frame or a bed board, and the mattress can be placed directly on the slat frame.

[0029] The lifting component 2 includes a motor 21 and an angle code 22. The motor 21 drives the lead screw 23 to rotate. A nut 24 is sleeved on the lead screw 23. A connecting block 25 is installed on the nut 24. One side of the connecting block 25 abuts against the mounting surface 14. When the lead screw 23 rotates, the nut 24 drives the connecting block 25 to move along the axis of the lead screw 23. An angle code 22 is installed on the connecting block 25, and the mattress support part is overlapped on the angle code 22.

[0030] Since the mounting surface 14 limits the connection block 25, the connection block 25 and the internal nut 24 cannot rotate. When the lead screw 23 rotates, the connection block 25 and the nut 24 will rotate along the axis of the lead screw 23, thereby enabling the angle code 22 to move up and down along the axis of the lead screw 23. The angle code 22 can be moved up or down by the forward and reverse rotation of the motor 21. The movement relationship between the lead screw 23 and the connection block 25 is a prior art and will not be described in detail here. By the rotation of the lead screw 23, the angle code 22 can be stopped at any height on the lead screw 23, achieving stepless adjustment, so that the mattress support part can adapt to mattresses of different thicknesses, so that the mattress can be adjusted to the height required by the consumer, and can be flexibly adjusted so that the height-adjustable bed can be installed with mattresses of different thicknesses.

[0031] When the fitted sheet needs to be replaced, the lifting member 2 is started to drive the rib frame on the corner bracket 22 to rise, so that the bottom surface of the mattress is higher than the upper edge of the bed frame and the foot of the bed, and the fitted sheet can be directly pulled out from the side of the mattress. When laying the fitted sheet, the fitted sheet can be directly inserted into the gap between the mattress and the rib frame to complete the replacement of the fitted sheet without moving the mattress, making the process of replacing the fitted sheet more labor-saving.

[0032] At the same time, the corner bracket 22 is raised to the highest position, so that sundries can be placed in the space below the mattress support part in the installation area 3. At the same time, the corner bracket 22 is raised to the highest position, so that the lower side of the mattress is exposed to the installation area 3, which is convenient for consumers to replace the fitted sheet. During daily cleaning and replacement, the mattress support part on the corner bracket 22 can be freely controlled by the remote control 4 to move up and down.

[0033] The upper end of the screw 23 of the utility model is equipped with a first abutment block 231, and the lower end of the screw 23 is equipped with a second abutment block 232. The first abutment block 231 and the second abutment block 232 are fixed to the mounting surface 14 by screws, and the screw 23 can be replaced later by screw fixation.

[0034] The lead screw 23 can be fixed on the mounting surface 14 by the first abutting block 231 and the second abutting block 232 . Meanwhile, the first abutting block 231 and the second abutting block 232 can also limit the connection block 25 to prevent the connection block 25 from being separated from the lead screw 23 .

[0035] The lifting component 2 also includes a first guide rail 26, which is installed on the installation surface 14. A slider 27 is slidably installed on the first guide rail 26. The angle code 22 is fixed to the slider 27 by screws for easy replacement. The angle code 22 can be replaced by a screwdriver.

[0036] Since the cross section of the angle bracket 22 is L-shaped, the angle bracket 22 is also sleeved on the first guide rail 26 through the slider 27 in the length direction of the angle bracket 22. The first rail increases the contact points between the angle bracket 22 and the mounting surface 14, which can improve the stability of the angle bracket 22 during the up and down movement.

[0037] First guide rails 26 are respectively installed on both symmetrical sides of the lead screw 23, and the sliders 27 on both sides can further fix the angle code 22 so that the angle code 22 can maintain a stable state during the movement.

[0038] A slide groove is installed on one side of the first guide rail 26 close to the mounting surface 14, and a second guide rail 28 is inserted in the slide groove. The second guide rail 28 is fixed to the mounting surface 14 by screws, and a limit block 282 is installed at the bottom end of the second guide rail 28. The first guide rail 26 abuts against the limit block 282, and a paddle 281 is rotatably installed on the upper end of the second guide rail 28, and the paddle 281 can be rotated to the upper side of the first guide rail 26.

[0039] By rotating the paddle 281 so that it does not block the first guide rail 26, the first guide rail 26 can be pulled out from the second guide rail 28, making it easier for maintenance personnel to remove it. Then, the first guide rail 26 is inserted into the second guide groove along its own slide groove, and the paddle 281 is continued to be rotated so that the paddle 281 and the limit block 282 fix the first guide rail 26, so that the angle code 22 remains stable during the lifting process.

[0040] The upper cover of the lifting member 2 is connected with an upper elastic cloth 5 and a lower elastic cloth 6, which are fixed on the mounting surface 14, the upper elastic cloth 5 is bonded to the side of the slider 27 and the upper side of the angle code 22, and the lower elastic cloth 6 is bonded to the side of the slider 27 and the lower side of the angle code 22.

[0041] A gap is formed between the upper elastic cloth 5 and the lower elastic cloth 6, and the corner bracket 22 can be exposed from the gap, so that the mattress support part can be overlapped on the side of the corner bracket 22, and the upper elastic cloth 5 and the lower elastic cloth 6 can cover the lifting member 2, thereby preventing the intrusion of dust or foreign objects from the outside, and preventing the screw 23 from driving the connecting block 25 to move and causing the connecting block 25 to jam. The lifting member 2 of the utility model can be covered by a whole piece of elastic cloth, and the screws on the corner bracket 22 pass through the elastic cloth and are fixed to the slider 27 and the connecting block 25.

[0042] Zippers are provided on the upper elastic cloth 5 and the lower elastic cloth 6. When an abnormal noise occurs during the lifting process of the corner code 22, the zippers can be opened and lubricating oil can be applied to the first slide rail and the lead screw 23, so that consumers can easily maintain the lifting component 2 and can easily inspect and replace the lifting component 2 at a later time; at the same time, the elastic cloth has a certain anti-noise function.

[0043] A remote controller 4 is installed on the bed screen 13. The remote controller 4 is provided with up, down, pause and switch buttons. The switch button can energize the motor 21 in the lifting component 2. The key instructions of the remote controller 4 are distributed and sent to the motors 21 in all the lifting components 2 through the controller. The power supply 7 inside the bed screen 13 provides power for the motor 21. Then, the up can control the motor 21 to rotate forward, the down can control the motor 21 to rotate reversely, and the pause can stop the motor 21 from rotating. The remote controller 4 is electrically connected to the motor 21 through wires. The wires are laid inside the bed 11, the bed foot 12 and the bed screen 13. The eight groups of lifting components 2 can move synchronously under the control of the remote controller 4. The wires are laid inside the bed 11, the bed foot 12 and the bed screen 13, so that all motors 21 can work. The wires are arranged inside to make the height-adjustable bed more beautiful as a whole.
