Description

Technical Field

[0001] This utility model relates to household furniture, and more particularly to an electric bed. Background Technology

[0002] With rising living standards and advancements in medical technology, people have increasingly higher demands for the functionality of beds. Existing beds, especially medical beds, are often equipped with a headrest function to accommodate different users' needs. However, in most beds on the market today, the operating component for the headrest function (usually a rocker handle) is located at the foot of the bed. This design forces users to get out of bed and manually turn the rocker handle when they need to raise the headboard.

[0003] For some patients or elderly people with limited mobility, this method of operation presents numerous inconveniences. First, they may be unable to get out of bed due to physical reasons; second, they may lack the strength to manually turn the lever handle to complete the lifting operation. Therefore, in most cases, they still need to rely on the assistance of others to complete the lifting operation. This not only increases the burden on others but may also take a long time while waiting for assistance. Furthermore, manually turning the handle is often time-consuming and strenuous, which further increases physical discomfort for those who are weak or suffering from illness.

[0004] Therefore, developing a bed that can automatically raise the headboard, is easy to operate, and can flexibly adjust the angle according to the user's needs has become an urgent need in the current market.

[0005] 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

[0052] See Figure 1 In this embodiment, the electric bed includes a bed frame 1, a bed board assembly 2, a support rotating plate 3, and an electric drive unit 4.

[0053] The bed board assembly 2 includes a fixed bed board 201 fixed on the bed frame 1 and a movable bed board 202 rotatably connected to the fixed bed board 201; the upper end of the support rotating plate 3 is rotatably connected to the movable bed board 202, and the lower end is slidably connected to the bed frame 1 in the horizontal direction; the electric drive unit 4 is installed on the bed frame 1 and connected to the middle part of the support rotating plate 3.

[0054] The electric drive unit 4 is used to drive the lower end of the support plate 3 to slide relative to the bed frame 1, so that the upper end of the support plate 3 drives the movable bed board 202 to rotate up and down.

[0055] The electric bed provided in this embodiment operates as follows:

[0056] ① Initial state: Both the movable bed board 202 and the fixed bed board 201 are in a horizontal state.

[0057] ② Start electric drive unit 4: The user starts electric drive unit 4 through the remote control or control buttons on the bedside.

[0058] ③ Sliding of the support plate 3: Driven by the electric drive unit 4, the lower end of the support plate 3 slides horizontally relative to the bed frame 1.

[0059] ④ Rotation of movable bed board 202: Since the upper end of the support rotating plate 3 is rotatably connected to the movable bed board 202, when the lower end of the support rotating plate 3 slides, the upper end of the support rotating plate 3 will drive the movable bed board 202 to rotate up and down around the edge of the fixed bed board 201.

[0060] ⑤ Headboard lifting: As the movable bed board 202 rotates, the headboard gradually rises until it reaches the angle or position set by the user.

[0061] ⑥ Stop electric drive unit 4: After the head of the bed reaches the required height, the user operates the control unit again to stop the operation of electric drive unit 4.

[0062] ⑦ Maintaining the status: After the electric drive unit 4 stops, the support plate 3 and the movable bed board 202 remain in their current positions, and the headboard remains raised for user use.

[0063] The electric bed provided in this embodiment achieves automatic head lifting through the electric drive unit 4 and the support rotating plate 3. Users do not need to manually turn the rocker handle at the foot of the bed, which solves the problem of time-consuming and laborious manual operation.

[0064] In this embodiment, the bed frame 1 includes a bed frame 101 and an electric drive fixing bracket 102. The bed board assembly 2 is installed above the bed frame 101; the electric drive fixing bracket 102 is fixed to the bottom of the bed frame 101 and surrounds to form an electric drive receiving cavity for accommodating the electric drive unit 4.

[0065] Furthermore, an electric drive base 103 is fixedly installed inside the electric drive receiving cavity, the electric drive base 103 is provided with a fixed limiting shaft 1031, and the support rotating plate 3 is provided with a movable strip groove 301 for the fixed limiting shaft 1031 to be inserted.

[0066] The electric drive mounting bracket 102 is provided with a fixed strip groove 1021 extending in the horizontal direction, and the lower end of the support rotating plate 3 is provided with a sliding limiting wheel 303 that is inserted into the fixed strip groove 1021 and slides along the fixed strip groove 1021.

[0067] When the electric drive unit 4 drives the support plate 3 to slide, the lower end of the support plate 3 will move relative to the bed frame 1 along the horizontal sliding limit wheel 303. During this movement, the support plate 3 will not only slide, but also rotate around the fixed limit shaft 1031. The fixed limit shaft 1031 is inserted into the movable strip groove 301, which serves to limit and provide a fulcrum, ensuring that the movement trajectory of the support plate 3 is stable and accurate.

[0068] The electric drive unit 4 includes a rotary drive mechanism 401 mounted on the electric drive base 103 and a drive gear 402 mounted on the drive end of the rotary drive mechanism 401. The side of the support plate 3 near the drive gear 402 is provided with a rack portion 302 that meshes with the drive gear 402.

[0069] If the rotary drive mechanism 401 drives the drive gear 402 to rotate in the forward direction, the support plate 3 gradually tends to a vertical state under the cooperation of the fixed limit shaft 1031 and the movable strip groove 301 (the included angle between the support plate 3 and the bed frame 101 gradually increases). During this process, the lifting height of the movable bed board 202 gradually increases.

[0070] Conversely, if the rotary drive mechanism 401 drives the drive gear 402 to rotate in the opposite direction, the support plate 3 gradually tends to a horizontal state under the combined action of the fixed limit shaft 1031 and the movable strip groove 301 (the included angle between the support plate 3 and the bed frame 101 gradually decreases). During this process, the lifting height of the movable bed board 202 gradually decreases.

[0071] In this embodiment, the electric drive unit 4 further includes a control component that is communicatively connected to the rotary drive mechanism 401 and is used to control the working state of the rotary drive mechanism 401.

[0072] Optionally, the control component includes control buttons fixed to the side of the bed frame 101 and electrically connected to the rotary drive mechanism 401, and / or a remote control wirelessly connected to the rotary drive mechanism 401. Further, the control buttons include a lift button 403 for momentarily controlling the rotary drive mechanism 401 to rotate forward, and a lower button 404 for momentarily controlling the rotary drive mechanism 401 to rotate backward.

[0073] The control buttons and remote control offer multiple control methods, increasing user convenience. In particular, the wireless communication connection of the remote control allows users to remotely control the bed without leaving the bed.

[0074] In this embodiment, the electric drive unit 4 further includes a distance sensor 405 installed on the inner side of the bed frame 101 and electrically connected to the rotary drive mechanism 401; the distance sensor 405 is used to detect the lifting height of the movable bed board 202.

[0075] The addition of distance sensor 405 enables real-time detection of the lifting height of movable bed board 202. When the lifting height of movable bed board 202 reaches the preset maximum value, the lifting button 403 is automatically disabled; conversely, when the lifting height of movable bed board 202 reaches the preset minimum value, the lowering button 404 is automatically disabled, thereby avoiding damage to the electric bed due to over-adjustment.

[0076] In summary, the electric bed provided in this embodiment has the following advantages:

[0077] ①Automated operation: Users can easily control the headboard lifting via remote control or bedside buttons. The electric drive unit 4 responds precisely, eliminating the hassle of manual adjustment and improving ease of use.

[0078] ② The structure is stable. The supporting rotating plate 3 is connected to the bed frame 1 through the sliding limit wheel 303 and the fixed strip groove 1021, which ensures that the head of the bed is stable and does not shake during the lifting process, thus enhancing the sense of safety in use.

[0079] ③ Safety protection: The built-in distance sensor 405 monitors the headboard height in real time and automatically disables the buttons when the preset limit is reached to prevent over-adjustment and effectively protect the bed structure and user safety.

[0080] ④ Precise adjustment: The electric drive unit 4 drives the gear 402 and rack to precisely match, enabling fine adjustments to the headboard height, meeting users' personalized needs for different heights and improving comfort.
