Description

Technical Field

[0001] This invention belongs to the field of home technology, specifically relating to a control method for a height-adjustable and tiltable bed frame. Background Technology

[0002] Traditional electric beds typically include an adjustable bed frame composed of multiple pivotally connected bed panels, such as a headboard, neck support, lumbar support, seat, thigh support, and leg support. This arrangement provides users with a variety of support options, allowing them to effectively adjust the electric bed configuration to achieve a desired position and level of comfort. While these traditional electric beds achieve their specific goals, sometimes there is a desire for an electric bed where the entire bed platform can be set at a specific height, or adjusted to any of several heights. Furthermore, there is sometimes a desire for an electric bed where the entire bed platform can be tilted, i.e., the head of the bed platform raised and the foot of the bed lowered, or vice versa. To meet customer needs, a control method for a height-adjustable tilting bed frame is proposed. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, this invention proposes a control method for a height-adjustable tilting bed frame, which has the advantage of realizing multiple movement modes of the bed frame.

[0005] A control method for a height-adjustable tilting bed frame according to an embodiment of the present invention is used to control the movement of the height-adjustable tilting bed frame, characterized by comprising the following steps: Step S1. Using at least one driver, drive the upper frame component to place the upper frame component in an intermediate raised position between the fully lowered position and the fully raised position relative to the lower frame component. Step S2. Move the head end and foot end of the upper frame component so that they move up or down respectively; Step S3. Repeat step S2 multiple times to achieve periodic motion, resulting in wave-like or swaying motion; During wave-like operation, in step S2, the head end and foot end of the upper frame component move sequentially to the fully raised position at predetermined times, then sequentially reach the middle raised position, then sequentially reach the fully lowered position, and finally sequentially reach the middle raised position. During the swing-like operation, in step S2, the head end and foot end of the upper frame component move simultaneously in opposite directions at a predetermined time, so that the head end of the upper frame component moves from the middle raised position to the fully raised position, while the foot end moves from the middle raised position to the fully lowered position. Then the foot end rises from the fully lowered position, passes the middle raised position, and reaches the fully raised position, while the head end falls from the fully raised position, passes the middle raised position, and reaches the fully lowered position. Subsequently, the foot end moves from the fully raised position to the middle raised position, while the head end moves from the fully lowered position to the middle raised position.

[0006] By controlling the head and tail ends of the upper frame component with a drive, the upper frame component bed platform can move in the same direction or move in opposite directions in sequence, thus realizing different movement modes of the upper frame component bed platform and achieving a wave-like or swaying running effect.

[0007] According to one embodiment of the present invention, the number of the drivers is at least two.

[0008] According to one embodiment of the present invention, each of the drivers includes a linear actuator.

[0009] According to one embodiment of the present invention, the driver is connected to a lifting arm, the lifting arm is operably connected to an upper frame component, and the driver is capable of driving the lifting arm to move the upper frame component relative to the lower frame component.

[0010] According to one embodiment of the present invention, the driver is connected to a controller, the controller being used to control the driver so that the driver drives the lifting arm.

[0011] According to one embodiment of the present invention, the controller is a programmable logic controller.

[0012] According to one embodiment of the present invention, the controller is a central processing unit.

[0013] The beneficial effect of this invention is that it uses a driver to control the head end and foot end of the upper frame component to move in the same direction or move in opposite directions in sequence, thereby realizing different movement modes of the upper frame component bed platform and achieving a wave-like or swaying running effect.

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

[0038] The control method of the height-adjustable tilting bed frame according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1: like Figure 1-9As shown, the control method for a height-adjustable tilting bed frame includes: a height-adjustable tilting bed frame 100, which includes an upper frame component 102, a lower frame component 104, two pairs of opposing lifting arms 106, and two pairs of opposing first alignment links 108. The upper frame component 102 can hold or install a conventional mattress. The lower frame component 104 is a rectangular frame component, including a first transverse lower frame assembly 110 located at the foot of the height-adjustable tilting bed frame 100, a second transverse lower frame assembly 112 located at the head of the height-adjustable tilting bed frame 100, and a pair of opposing longitudinally extending lower frame assemblies 114. The upper frame component 102 is also a rectangular frame component, including a first transverse upper frame assembly 116 located at the foot of the height-adjustable tilting bed frame 100, a second transverse upper frame assembly 118 located at the head of the height-adjustable tilting bed frame 100, and a pair of opposing longitudinally extending upper frame assemblies 120.

[0040] The lower ends of two pairs of opposing first alignment links 108 are pivotally connected to a pair of opposing longitudinally extending lower frame assemblies 114 of the lower frame component 104 at longitudinally spaced positions, which are located at... Figure 2 The first connection point 122 is located near the first transverse lower frame assembly 110 and the second transverse lower frame assembly 112 of the lower frame component 104; while the upper ends of the two pairs of opposing first alignment links 108 are pivotally connected to a pair of opposing longitudinally extending upper frame assemblies 120 of the upper frame component 102 at longitudinally spaced positions, which are located at... Figure 2 The second connection point 124 is located near the first transverse upper frame assembly 116 and the second transverse upper frame assembly 118 of the upper frame component 102. A second alignment link 126 is provided between the two first alignment links 108 on the lower frame assembly 114. The lower end of the second alignment link 126 is pivotally connected to a location near the center of the lower frame assembly 114, and the upper end of the second alignment link 126 is pivotally connected to a location near the center of the upper frame assembly 120.

[0041] like Figure 1 , Figure 7-9 The lower ends of the two pairs of oppositely arranged lifting arms 106 are respectively pivotally mounted in the two pairs of oppositely arranged first mounting brackets 132, which is the third connection point 134. The first mounting brackets 132 are fixedly connected to the lower frame assembly 114. The upper ends of the two pairs of oppositely arranged lifting arms 106 are each provided with rollers 136, which are adapted to roll into the two pairs of oppositely arranged longitudinally extended second mounting brackets 138. The second mounting brackets 138 are fixedly connected to a pair of oppositely arranged longitudinally extended upper frame assemblies 120 of the upper frame component 102.

[0042] Furthermore, it can be seen that, in order to actuate the two pairs of opposing lifting arms 106, causing the upper frame component 102 to rise, lower, or tilt relative to the lower frame component 104, each pair of opposing lifting arms 106 is equipped with a linear actuator 140. More specifically, each linear actuator 140 includes a motor end 142, a cylinder housing 144, and a telescopic rod component 146. The motor end 142 is pivotally connected via a suitable U-shaped clamp connector 148 to one of a pair of opposing longitudinally extending lower frame assemblies 114 of the lower frame component 104, while the free distal portion of the telescopic rod component 146 is pivotally connected via a first end portion of an L-shaped connecting bracket 150, at a fourth connection point 152. Further, as... Figure 9 As shown, a pair of crossbeams 154 are fixedly connected to the first mounting bracket 132, which is arranged opposite to each other. The lower ends of the two pairs of oppositely arranged lifting arms 106 are pivotally mounted within the first mounting bracket 132; and a pair of C-shaped mounting brackets 156 are mounted on the approximate center portion of the pair of crossbeams 154. Figure 1 As shown, each C-shaped mounting bracket 156 includes an integral cylindrical bushing 158. The upright or shaft of the first bell-shaped crank 160 is rotatably disposed within the cylindrical bushing 158. Figure 7 As shown, the first end portion of the first bell-shaped crank 160 is pivotally connected to the distal free end portion of the L-shaped connecting bracket 150 at the fifth connection point 162. The opposite second end of the first bell-shaped crank 160 is pivotally connected to the first end portion of the first connecting rod 164 at the sixth connection point 166. Furthermore, the opposite second end portion of the first connecting rod 164 is pivotally connected to the first end portion of the first of a pair of opposing second bell-shaped cranks 168 at the seventh connection point 170. Figure 8 As shown, the opposite second end portion of each second bell-shaped crank 168 is pivotally connected to the first end portion of a pair of opposing C-shaped connectors 172 at the eighth connection point 174. The opposite second end portion of each C-shaped connector 172 actually forms a first bushing 176, within which the pivot shaft 178 of the lifting arm 106 corresponding to the first bushing 176 is pivotally disposed. The upright of the second bell-shaped crank 168 is rotatably disposed within a second bushing 180, which is integrally connected to a third mounting bracket 182, which in turn is fixedly connected to a first mounting bracket 132. The first end portion of the second connecting rod 184 is pivotally connected to the first bell-shaped crank 160 at the ninth connection point 186, while the opposite second end portion of the second connecting rod 184 is pivotally connected to the second of the pair of opposing second bell-shaped cranks 168 at the seventh connection point 170.

[0043] Working principle: When either linear actuator 140 is activated and the telescopic rod component 146 retracts, the first bell-shaped crank 160 will move along... Figure 7 The counterclockwise rotation, as shown, causes the first connecting rod 164 to move to the left, thereby causing the first of the pair of opposing second bell-shaped cranks 168 to rotate along... Figure 7 Rotate clockwise as shown. Therefore, from Figure 7 and Figure 8 As can be understood, when the first of a pair of opposing second bell-shaped cranks 168 rotates clockwise, the first of a pair of opposing C-shaped connectors 172 will move in the direction shown by arrow A, thereby causing the lower end of the first of a pair of opposing lifting arms 106 to rotate in the direction shown by arrow B, thus raising the upper frame component 102. Simultaneously, the second connecting rod 184 will move along... Figure 7 The movement to the right causes the second of a pair of opposing second bell-shaped cranks 168 to rotate counterclockwise, which in turn moves the second of a pair of opposing C-shaped connectors 172, causing the lower end of the second of a pair of opposing lifting arms 106 to rotate, thus raising the upper frame component 102. It should be understood that activation of the linear actuator 140 will cause the upper frame component 102 of the height-adjustable tilting bed frame 100 to rise relative to the lower frame component 104, while activation of the linear actuator 140 in the opposite direction or mode will cause the upper frame component 102 of the height-adjustable tilting bed frame 100 to descend relative to the lower frame component 104.

[0044] Therefore, it can be implemented as needed. Figure 2-5 The various relative positions of the upper frame component 102 of the height-adjustable tilting bed 100 relative to the lower frame component 104 are shown. Furthermore, the pair of linear actuators 140 are operatively connected to a suitable controller 187, such as a programmable logic controller (PLC) or a central processing unit (CPU). The PLC or CPU is adapted to control the pair of linear actuators 140, thereby controlling the two pairs of opposing lifting arms 106, causing the upper frame component 102 of the height-adjustable tilting bed 100 to rise and fall relative to the lower frame component 104, to achieve… Figure 2-5 Various positions, modes, or states are shown. Furthermore, a programmable logic controller (PLC) or central processing unit (CPU) can control the linear actuator 140 to continuously raise and lower the opposite ends of the upper frame component 102 of the liftable tilting bed 100 relative to the lower frame component 104 in a predetermined periodic manner, thereby effectively simulating a "wave-floating" or swaying operating mode, which will be described in more detail below.

[0045] Regarding the first alignment link 108 and the second alignment link 126, each first alignment link 108 includes a first link component 188 and a second link component 190 pivotally connected at an eleventh connection point 192, while each intermediate second alignment link 126 includes a third link component 194 and a fourth link component 196 pivotally connected at a twelfth connection point 198. Furthermore, the first link component 188, the second link component 190, the third link component 194, and the fourth link component 196 are pivotally connected at the eleventh connection point 192 and the twelfth connection point 198, respectively, such that even when the upper frame component 102 of the height-adjustable tilting bed frame 100 is in the fully raised position relative to the lower frame component 104, the first link component 188, the second link component 190, the third link component 194, and the fourth link component 196 will never be positioned 180° apart. This effectively prevents the first link component 188, the second link component 190, the third link component 194, and the fourth link component 196 from locking together, thereby preventing these link components from being unable to fold or retract together when it is necessary to lower the upper frame component 102 of the height-adjustable tilting bed frame 100 relative to the lower frame component 104.

[0046] Example 2: like Figure 10 As shown, the difference from Embodiment 1 is that the height-adjustable tilting bed frame 100 is equipped with an adjustable bed frame assembly. This adjustable bed frame assembly includes a bed frame component 202 adapted to and fixedly connected to the top of the upper frame component 102 of the height-adjustable tilting bed frame 100; at least one seat plate component 204 fixedly connected to the bed frame frame component 202; a thigh plate component 206 whose first end is pivotally connected to the first end of the at least one seat plate component 204; and a lower leg plate component 208 whose first end is pivotally connected to the second end of the thigh plate component 206. Furthermore, the adjustable bed frame assembly also includes a lumbar support component 210 whose first end is pivotally connected to the second end of the at least one seat plate component 204; a backrest component 212 whose first end is pivotally connected to the second end of the lumbar support component 210; and a neck support component 214 pivotally connected to the second end of the backrest component 212.

[0047] Example 3: like Figure 11 As shown, the difference from Embodiment 2 is that the adjustable bed frame assembly is adapted to be directly fixed to the upper frame component 102 of the height-adjustable and tiltable bed frame 100. More specifically, the adjustable bed frame assembly includes a bed frame component 202, which is integrated with the upper frame component 102; it can also be understood that the bed frame component 202 is the same as the upper frame component 102. The seat plate component 204 is fixedly connected to the upper frame component 102.

[0048] The control steps for wave operation mode are as follows: like Figure 12-19 As shown, the height-adjustable tilt bed frame 100 is mounted on multiple upright legs 101, allowing the legs 101 to support it on the floor or other platform. Additionally, a cushion 103 is installed on the height-adjustable tilt bed frame 100. The cushion 103 surrounds the perimeter of the height-adjustable tilt bed frame 100, providing protection by shielding the side walls of the height-adjustable tilt bed frame 100. To achieve the wave-like operation mode of the height-adjustable tilt bed frame 100, the upper frame component 102 is first moved relative to the lower frame component 104 to a fully lowered state, at which point both the upper frame component 102 and the lower frame component 104 are horizontal and parallel to each other; then, the upper frame component 102 is moved to an intermediate raised position between the fully raised and fully lowered states, at which point the upper frame component 102 and the lower frame component 104 are again horizontally aligned and parallel. Then, the head end of the upper frame component 102 rises within a predetermined time period (e.g., 1 second), and then the foot end of the upper frame component 102 rises within another predetermined time period (e.g., 1 second).

[0049] Subsequently, the head end of the upper frame component 102 descends within a predetermined time period (e.g., 1 second), followed by the tail end of the upper frame component 102 descending within another predetermined time period (e.g., 1 second). Therefore, it is easy to understand that the cycle of the upper frame component 102's rising and falling at both ends to form a wave-like motion is 2 seconds, and the entire wave cycle is, for example, 4 seconds. After the initial 4-second cycle, the wave operation pattern can be repeated a predetermined number of times, or the two linear actuators 140 can be deactivated by a specific computer program programmed in a programmable logic controller (PLC) or central processing unit (CPU). Furthermore, the PLC or CPU can be programmed to deactivate the linear actuators 140 within a predetermined time period to prevent overheating of the motor end 142. Further, the PLC or CPU will automatically put the linear actuators 140 into a "timeout" state after a predetermined time period (e.g., 5 minutes), thereby moving the upper frame component 102 to... Figure 12 and Figure 16 At the fully descending or folding position shown, all wave operation modes cease execution. The linear actuator 140 automatically enters the "timeout" state, meaning that after a preset time is reached, the linear actuator 140 automatically stops operating to prevent damage from prolonged operation.

[0050] The control steps for the swing operation mode are as follows: First, the upper frame component 102 is moved relative to the lower frame component 104 to a fully lowered or folded state, at which point both the upper frame component 102 and the lower frame component 104 are horizontally oriented and parallel to each other. Then, the upper frame component 102 is moved to an intermediate raised position between the fully raised and fully lowered states, at which point the upper frame component 102 and the lower frame component 104 are again horizontally oriented and parallel. Upon reaching this intermediate position, the height-adjustable tilting bed frame 100 can begin its rocking operation mode. Therefore, the headboard end of the upper frame component 102 rises to the fully raised position within a predetermined time period (e.g., 2 seconds), while the footboard end of the upper frame component 102 lowers to the fully lowered position; subsequently, the movement of the headboard and footboard ends of the upper frame component 102 stops for a predetermined time period (e.g., 2 seconds).

[0051] Subsequently, the head and foot ends of the upper frame component 102 move in opposite directions; that is, the foot end of the upper frame component 102 rises to its fully raised position within a predetermined time period (e.g., 4 seconds), while the head end of the upper frame component 102 descends within the same predetermined time period (e.g., 4 seconds). Afterward, the movement of the head and foot ends of the upper frame component 102 stops again for a predetermined time period (e.g., 2 seconds). The additional time interval is because in the second cycle of the rocking motion, both the head and foot ends of the upper frame component 102 must pass through the initial horizontal intermediate raised position. The complete cycle can be repeated, with a total cycle of 5 minutes, after which the upper frame component 102 will move to... Figure 12 and Figure 16 When the position is fully lowered or folded as shown, all swing operation modes cease to execute.

[0052] Based on the above teachings, many variations and modifications of the present invention are possible. For example, in addition to the wave or rocking operating mode, other different periodic operating modes can be implemented. Furthermore, a larger-amplitude wave operating mode can be achieved by setting the operating time of each head and foot drive to a period longer than the aforementioned 2 seconds (e.g., 3 seconds); similarly, a longer-wavelength wave operating mode can be achieved by extending the time interval between each operation of each head and foot drive. Similar different time periods can also be used to start or stop the rocking operating mode. Therefore, it should be understood that the present invention may be practiced in ways other than those specifically described herein within the scope of the appended claims.
