Description
Technical Field
[0001] This utility model relates to the field of home furnishing technology, and more specifically to an adjustable-angle lift bed backrest. Background Technology
[0002] The primary purpose of a bed is for sleeping and resting, and it is one of the most important pieces of furniture in the bedroom. The headboard is an important component of the bed, providing comfortable support and helping to maintain correct posture, thereby relieving pressure on the lower back and neck caused by prolonged leaning. It not only fills the gap between the back and the bed board, maintaining the natural physiological curve of the spine, but also enhances the aesthetics and overall comfort of the bedroom.
[0003] Insufficient technology: However, most existing bed backrests are fixed structures, which cannot adjust the height and angle of the backrest according to usage needs, affecting the user's comfort. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable angle lifting bed backrest to solve the problems existing in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle liftable bed backrest, including a base assembly, and further including a bed board assembly and a starting assembly. The bottom end of the bed board assembly is movably connected to the top end of the base assembly, and the side of the starting assembly is fixedly connected to the side of the base assembly. The base assembly includes a base plate, and the bed board assembly includes a bed board body. The inner wall of the top end of the bed board body is movably connected to the top end of the base plate. A caster wheel is fixedly connected to the bottom end of the bed board body, and a support frame is fixedly connected to the top end of the bed board body. A hinge is fixedly connected to the side of the support frame, and a backrest is movably connected to the top end of the support frame via the hinge. A side plate is fixedly connected to the side of the base plate, and the side of the side plate is movably connected to the side of the backrest.
[0006] Furthermore, a support plate is fixedly connected to the side of the backrest, and the support plate has an arc-shaped structure. Support wheels are movably sleeved on the side of the side plate corresponding to the position of the support plate.
[0007] Furthermore, the hinge is located on the side of the support frame near the side plate, which is used to limit the backrest and effectively prevent the backrest from tilting towards the main body of the bed board.
[0008] Furthermore, the starting component includes a connecting frame, the top of which is fixedly connected to the inner wall of the top of the bed board body, a linear motor is fixedly connected to the bottom of the connecting frame, a linear guide rail is driven to the side of the linear motor, and the side of the linear guide rail is fixedly connected to the inner wall of the side of the bottom plate.
[0009] Furthermore, a slide rail is fixedly connected to the top of the base plate, and a roller is movably sleeved on the side of the connecting frame, with the bottom end of the roller movably connected to the bottom end of the slide rail.
[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a linear motor to move laterally along a linear guide rail, which in turn pushes the bed board body to move laterally along the top of the base plate. The backrest rotates along the hinge under the action of gravity, and the support wheels roll along the support plate to support the backrest, reducing the friction between the backrest and the side plate and reducing wear. This allows the backrest to maintain a suitable angle and height, ensuring the user's comfort. Attached Figure Description

Detailed Implementation
[0013] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adjustable angle lifting bed backrest involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0014] Reference Figures 1 to 4This utility model provides an adjustable-angle height-adjustable bed backrest, including a base assembly 1, a bed board assembly 2, and an activation assembly 3. The bottom end of the bed board assembly 2 is movably connected to the top end of the base assembly 1, and the side of the activation assembly 3 is fixedly connected to the side of the base assembly 1. The base assembly 1 includes a base plate 102, and the bed board assembly 2 includes a bed board body 201. The inner wall of the top end of the bed board body 201 is movably connected to the top end of the base plate 102. A caster wheel 202 is fixedly connected to the bottom end of the bed board body 201, and a support frame 205 is fixedly connected to the top end of the bed board body 201. A hinge 206 is fixedly connected to the side of the support frame 205. The top of the support frame 205 is movably connected to the backrest 204 via a hinge 206. The side of the base plate 102 is fixedly connected to the side plate 101. The side of the side plate 101 is movably connected to the side of the backrest 204. During use, the backrest 204 can rotate along the hinge 206. Under the action of gravity, the backrest 204 is pressed tightly against the side of the side plate 101. During use, the starting component 3 drives the bed board body 201 to move to the left at the top of the base plate 102 to adjust the length of the bed. At the same time, the backrest 204 rotates downward under the action of gravity, thereby adjusting the height and angle of the backrest 204 to ensure the comfort of the user when leaning against the backrest 204.
[0015] The backrest 204 is fixedly connected to a support plate 203, which has an arc-shaped structure. The side of the side plate 101 is movably fitted with a support wheel 103 corresponding to the position of the support plate 203. The support wheel 103 rolls along the support plate 203 to support the backrest 204. When the bed board body 201 moves to the right, the support wheel 103 pushes the support plate 203 to make the backrest 204 rotate upward.
[0016] The hinge 206 is located on the side of the support frame 205 near the side plate 101. It is used to limit the backrest 204 and effectively prevent the backrest 204 from tilting towards the bed board body 201, thus preventing injury to people when the backrest 204 is upright.
[0017] The starting component 3 includes a connecting frame 301. The top of the connecting frame 301 is fixedly connected to the inner wall of the top of the bed board body 201. A linear motor 304 is fixedly connected to the bottom of the connecting frame 301. A linear guide rail 302 is connected to the side of the linear motor 304. The side of the linear guide rail 302 is fixedly connected to the inner wall of the side of the base plate 102. The linear motor 304 moves laterally along the linear guide rail 302, pushing the bed board body 201 to move laterally along the top of the base plate 102, thereby realizing the retraction of the bed and the angle adjustment of the backrest 204.
[0018] The top of the base plate 102 is fixedly connected to a slide rail 303, and the side of the connecting frame 301 is movably fitted with a roller 305. The bottom end of the roller 305 is movably connected to the bottom end of the slide rail 303. When the bed board body 201 moves laterally, the roller 305 slides along the slide rail 303, reducing the friction between the base plate 102 and the bed board body 201 and supporting the bed board body 201.
[0019] The working principle of this utility model is as follows: The linear motor 304 moves laterally along the linear guide rail 302, pushing the bed board body 201 to move laterally along the top of the base plate 102. The backrest 204 rotates along the hinge 206 under the action of gravity, and the support wheel 103 rolls along the support plate 203 to support the backrest 204, reducing the friction between the backrest 204 and the side plate 101, reducing wear, so that the backrest 204 maintains a suitable angle and height, ensuring the comfort of the user.
[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
