Description

Technical Field

[0001] This utility model belongs to the field of electric furniture technology, specifically relating to electric beds, and more particularly to an electric adjustable bed frame. Background Technology

[0002] Traditional electric bed frames typically include a bed frame, head and neck panel, back panel, lumbar panel, at least one seat panel, leg panel, and foot panel, each panel being adjustable to different positions. For example, from... Figure 1 and Figure 2 As can be clearly seen, a conventional existing electric bed frame, as indicated by reference numeral 100, includes a sub-base frame 102, a sub-head and neck panel 104, and a sub-back panel 106. One end of the sub-back panel 106 is pivoted and hinged to one end of the sub-head and neck panel 104, and the other end is pivoted and hinged to one end of the sub-lumbar panel 108. At least one sub-seat panel 110 is fixed to the sub-base frame 102, and one end of it is pivoted and hinged to the other end of the sub-lumbar panel 108. One end of the sub-leg panel 112 is pivoted and hinged to the other end of at least one sub-seat panel 110, and one end of the sub-foot panel 114 is pivoted and hinged to the other end of the sub-leg panel 112. These structures... Figure 3-5 As can be seen more clearly, the secondary leg panel 114 can only pivot clockwise relative to the plane P where the secondary leg panel 112 is located, resulting in an angle α formed by the pivoting motion of the secondary leg panel 114 relative to the secondary leg panel 112. Although this movement allows the electric bed frame 100 to be used for leg elevation, the overall adjustable angle is still limited, and it cannot meet the needs for higher leg elevation such as stretching. To increase the adjustable angle, an electrically adjustable bed frame is proposed. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, this utility model proposes an electrically adjustable bed frame, which has the advantage of increasing the adjustable angle.

[0005] An electrically adjustable bed frame according to an embodiment of the present invention includes: a bottom frame, a seat panel, a back panel, a leg panel, a foot panel, and multiple drive components; the seat panel is fixed to the bottom frame; one end of the back panel is operably connected to one end of the seat panel; one end of the leg panel is operably connected to the other end of the seat panel; one end of the foot panel is operably connected to the other end of the leg panel; multiple drive components are operably connected to the back panel, leg panel, and foot panel; wherein at least one of the drive components can drive the foot panel to pivot in both forward and reverse directions relative to the leg panel in the plane of the leg panel.

[0006] According to one embodiment of the present invention, the foot panel pivots relative to the leg panel in the forward and reverse directions on the plane of the leg panel, and the pivoting motion forms an angle α and an angle β of up to 90° between the plane of the foot panel and the plane of the leg panel.

[0007] According to one embodiment of the present invention, the foot panel can be placed perpendicular to the bottom frame.

[0008] According to one embodiment of the present invention, when the leg panel is at a 45° angle to the bottom frame, the distance between the free distal end of the foot panel and the bottom frame is not less than 18 inches.

[0009] According to one embodiment of the present invention, a head and neck panel is further included, which is operably connected to the other end of the back panel.

[0010] According to one embodiment of the present invention, the head and neck panel can be placed perpendicular to the bottom frame.

[0011] According to one embodiment of the present invention, when the bottom frame of the head and neck panel and the foot panel are both vertically arranged, the head and neck panel and the foot panel are parallel to each other.

[0012] According to one embodiment of the present invention, when the head and neck panel and the foot panel are parallel to each other, the distance between the head and neck panel and the foot panel is less than 50 inches.

[0013] The beneficial effect of this utility model is that it uses a drive component to drive the foot panel to pivot in the forward and reverse directions relative to the leg panel on the plane of the leg panel. Therefore, while the leg panel can be angled, the adjustment angle of the foot panel is increased, thereby increasing the overall adjustment angle to make it suitable for applications such as leg stretching. The head and neck panel can pivot relative to the back panel to a vertical position or within a vertical plane, and the foot panel can pivot forward and backward relative to the plane P where the leg panel is located, or also within a vertical plane. This allows the feet and head to be placed vertically when a person lies on the electrically adjustable bed frame, facilitating the stretching of the hamstrings, back muscles, and neck muscles. At the same time, the core muscles of the torso can also perform beneficial abdominal exercises.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The electrically adjustable bed frame of this utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-13 As shown, the electrically adjustable bed frame according to an embodiment of the present invention includes: a bottom frame 202, a head and neck panel 204, a back panel 206, a lumbar panel 210, a seat panel 214, a leg panel 218, and a foot panel 222. One end of the back panel 206 is connected to one end of the head and neck panel 204 via a pivot and hinge at a first connection 208, and the other end is connected to one end of the lumbar panel 210 via a pivot and hinge at a second connection 212. At least one seat panel 214 is fixed to the bottom frame 202, and one end of it is connected to the other end of the lumbar panel 210 via a pivot and hinge at a third connection 216. One end of the leg panel 218 is connected to the other end of at least one seat panel 214 via a pivot and hinge at a fourth connection 220. One end of the foot panel 222 is connected to the other end of the leg panel 218 via a fifth connection 224 via a pivot and hinge.

[0022] The foot panel 222 can pivot in both forward and reverse directions relative to the plane P containing the leg panel 218, forming angles α and β of at least 90°. And as... Figure 5 As shown, in conventional bed frames 100, the secondary leg panel 114 can only move in the forward direction, forming only an included angle α. The leg panel 222 can be positioned in a vertical plane, such as... Figure 6 , Figure 8 and Figure 10 As shown, or perpendicular to the underlying frame 202. Therefore, as... Figure 7 As shown, in the conventional bed frame 100, when the secondary leg panel 112 is at a 45° angle, the height H1 of the distal free end portion of the secondary leg panel 114 relative to the secondary bottom frame 102 is less than 16 inches; while as... Figure 8 As shown, in the improved electrically adjustable bed frame 200 of this invention, the height H2 of the distal free end portion of the foot panel 222 is at least 18 inches relative to the bottom frame 202 when the leg panel 218 is at a 45° angle. When a person lies on the electrically adjustable bed frame 200 of this invention, their feet will be positioned vertically, facilitating stretching of the hamstrings and back muscles.

[0023] Reference Figure 9 and Figure 10 Unlike traditional bed frames 100, the head and neck panel 204 can not only pivot relative to the back panel 206, but more importantly, it can pivot relative to the back panel 206 to a vertical position or within a vertical plane, such as... Figure 10 As shown. When this movement of the head panel 204 is combined with the movement of the foot panel 222, since the foot panel 222 can pivot in both forward and reverse directions relative to the plane P where the leg panel 218 is located, forming angles α and β of at least 90°, it can also be in a vertical plane, such as... Figure 6 , Figure 8 and Figure 10 As shown, the head and neck panel 204 is positioned within a vertical plane P1, which is perpendicular to the bottom frame 202 and parallel to the vertical plane P2 containing the foot panel 222. Thus, the distance D1 between the head and neck panel 204 and the foot panel 222 is significantly less than 50 inches, while the distance D2 between the distal free end of the secondary head and neck panel 104 and the distal free end of the secondary foot panel 114 in a conventional bed frame 100 is significantly greater than 50 inches. Therefore, when a person lies on the electrically adjustable bed frame 200 of this invention, their feet and head will be vertically positioned, facilitating stretching of the hamstrings, back muscles, and neck muscles. Simultaneously, the core muscles of the torso can also undergo beneficial abdominal exercises.

[0024] The multiple drive components are a first linear actuator 226, a second linear actuator 228, a third linear actuator 232, and a fourth linear actuator 230.

[0025] Specifically, the leg panel 218 is provided with a first connector 2261, and the foot panel 222 is provided with a second connector 2262. The two ends of the first linear actuator 226 are pivotally connected to the first connector 2261 and the second connector 2262, respectively. The first linear actuator 226 is used to adjust the relative positional relationship between the foot panel 222 and the leg panel 218. The first linear actuator 226 has a preset position, an output position, and a retracted position. When the output end of the first linear actuator 226 is in the preset position, the foot panel 222 and the leg panel 218 are located on the same plane. When the output end of the first linear actuator 226 is adjusted from the preset position to the output position, the foot panel 222 rotates counterclockwise around the fifth connection 224. When the output end of the first linear actuator 226 is adjusted from the preset position to the retracted position, the foot panel 222 rotates clockwise around the fifth connection 224.

[0026] The leg panel 218 is provided with a third connector 2281, and the bottom frame 202 is provided with a fourth connector 2282. The two ends of the second linear actuator 228 are pivotally connected to the third connector 2281 and the fourth connector 2282 respectively. The second linear actuator 228 is used to adjust the angle between the leg panel 218 and the bottom frame 202 so that the leg panel 218 is in a parallel state or a raised state.

[0027] The bottom frame 202 is provided with a main spindle 2021 and a fifth connector 2022. The fifth connector 2022 is located at one end of the bottom frame 202. The main spindle 2021 is located below the back panel 206. The two ends of the main spindle 2021 are pivotally connected to the bottom frame 202. The two ends of the third linear actuator 232 are pivotally connected to the main spindle 2021 and the fifth connector 2022 respectively. The third linear actuator 232 is used to drive the main spindle 2021 to rotate around its circumference.

[0028] A set of support rods 20211 is fixed on the main spindle 2021, and a set of guide rails 2061 is fixed on the back panel 206. The guide rails 2061 are aligned with the length direction of the bottom frame 202. One end of the support rod 20211 is fixedly connected to the main spindle 2021, and the other end is slidably connected to the guide rail 2061. During the rotation of the main spindle 2021, the support rods 20211 drive the back panel 206 to move between a parallel state and a raised state. When the back panel 206 is raised, it can also raise the waist panel 210 by a certain angle.

[0029] The back panel 206 is provided with a sixth connector 2301, and the head and neck panel 204 is provided with a seventh connector 2302. The two ends of the fourth linear actuator 230 are pivotally connected to the sixth connector 2301 and the seventh connector 2302 respectively. The fourth linear actuator 230 is used to adjust the relative angle between the head and neck panel 204 and the back panel 206.
