[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0077] Please refer to Figure 1 This application provides an infant care device, including a support component 100, a movable plate 200, a bed component 300, and a drive device 400.

[0078] The support assembly 100 has a first pivot portion 111 and a second pivot portion 112, which are spaced apart along a first axis L1. A movable plate 200 is rotatably connected to both the first pivot portion 111 and the second pivot portion 112, allowing the movable plate 200 to be rotatably mounted on the support assembly 100 about the first axis L1. A bed assembly 300 is mounted on the movable plate 200 and is used to support the infant. A drive device 400 is connected to the movable plate 200 and drives the movable plate 200 to rotate about the first axis L1, thereby causing the movable plate 200 to move the bed assembly 300. The bed assembly 300 is located on one side of the movable plate 200 in the thickness direction, while the first pivot portion 111, the second pivot portion 112, and the drive device 400 are located on different sides of the movable plate 200 in the circumferential direction.

[0079] Therefore, the side where the bed assembly 300 is located can be the upper surface of the movable plate 200. Thus, when the bed assembly 300 is installed on one side (i.e., the upper surface) of the movable plate 200 in the thickness direction, compared to having the first pivot 111, the second pivot 112, and the drive device 400 all located on the other side (i.e., the lower surface) of the movable plate 200 in the thickness direction, this embodiment of the application, by respectively locating the first pivot 111, the second pivot 112, and the drive device 400 on different sides of the movable plate 200 in the circumferential direction, can avoid the first pivot 111, the second pivot 112, and the drive device 400 obstructing the side of the movable plate 200 away from the bed assembly 300 (i.e., the lower surface), thereby making the lower surface of the movable plate 200 easier to clean and disinfect.

[0080] Please continue to refer to this. Figure 2 For example, the movable panel 200 includes a top wall 21, a bottom wall 22, and a connecting ring wall 23. The top walls 21 are arranged opposite to each other, and the connecting ring wall 23 surrounds and connects the top walls 21 and the bottom walls 22. The bed assembly 300 is installed on the top wall 21. The first pivot 111, the second pivot 112, and the drive device 400 are located on different sides of the connecting ring wall 23, thereby facilitating the cleaning and disinfection of the bottom wall 22 (lower surface) of the movable panel 200. In addition, by adopting a design with different sides, the fixed use space of the infant care equipment in the longitudinal direction can be saved, thereby increasing the flexible use space of the infant care equipment in the longitudinal direction, which is convenient for medical staff of different heights and for different care needs of medical staff.

[0081] The above is an overall description of the technical solutions of the embodiments of this application.

[0082] In some embodiments, the first axis L1 passes through the middle of the movable plate 200. At least one end of the bottom wall 22 is inclined toward the top wall 21 along a direction perpendicular to the first axis L1.

[0083] Taking the first axis L1 passing through the middle of the movable plate 200 along its length as an example, when both ends of the bottom wall 22 are inclined towards the top wall 21, it can also be understood that the bottom wall 22 has a structure that is low in the middle and high at both ends along the length of the movable plate 200. Therefore, given the limited space below the bottom wall 22, compared to the bottom wall 22 and top wall 21 being parallel, either end of the movable plate 200 in this embodiment can be rotated downwards at a larger angle. Thus, when the angle at which the movable plate 200 needs to rotate is determined, a smaller space needs to be reserved below the movable plate 200 in the support assembly 100 to facilitate the miniaturization of the infant care equipment.

[0084] In some embodiments, the outer surface of the connecting annular wall 23 includes a first side surface 231, a second side surface 232, and a third side surface 233. The first side surface 231 and the second side surface 232 are located on opposite sides of the movable plate 200, and the second side surface 232 and the third side surface 233 are located on adjacent sides of the movable plate 200. Specifically, the first side surface 231 faces the first pivot portion 111, the second side surface 232 faces the second pivot portion 112, and the third side surface 233 faces the drive device 400. Furthermore, the space at the first side surface 231, the second side surface 232, and the third side surface 233 of the movable plate 200 can be fully utilized to rationally arrange the first pivot portion 111, the second pivot portion 112, and the drive device 400.

[0085] Please refer to this as well. Figure 2 and Figure 3 In some embodiments, the drive unit 400 extends along the third side 233 in its longitudinal direction. Therefore, compared to the drive unit 400 being perpendicular to the third side 233, the overall length of the drive unit 400 and the movable plate 200 can be smaller in the direction perpendicular to the third side 233. Furthermore, the structure of the infant care device on the side of the movable plate 200 containing the third side 233 can be more compact, facilitating the miniaturization of the infant care device.

[0086] In some embodiments, the movable plate 200 is detachably rotatably connected to the first pivot 111 and detachably rotatably connected to the second pivot 112, so that the movable plate 200 is detachably mounted on the support assembly 100. Therefore, in actual use, the movable plate 200 can be disconnected from both the first pivot 111 and the second pivot 112, and then removed to facilitate cleaning and disinfection of its lower surface.

[0087] Please continue to refer to this. Figure 4 In some embodiments, one of the first pivot portion 111 and the first side surface 231 is provided with a first pivot shaft 24, and the other is provided with a first mounting hole 1111. The first pivot shaft 24 is telescopic or movable along the first axis L1. The first pivot shaft 24 can be inserted into the first mounting hole 1111 along the first axis L1 to rotatably connect the movable plate 200 with the first pivot portion 111, and the first pivot shaft 24 can be withdrawn from the first mounting hole 1111 along the first axis L1 to disconnect the first pivot portion 111 from the movable plate 200. Therefore, the assembly and disassembly of the movable plate 200 and the first pivot portion 111 can be easily completed by telescopic or movable first pivot shaft 24.

[0088] In some embodiments, one of the second pivot portion 112 and the second side surface 232 has a protruding second pivot shaft 25, and the other has a second mounting hole 1121. The second pivot shaft 25 is telescopic or movable along the first axis L1. The second pivot shaft 25 can be inserted into the second mounting hole 1121 along the first axis L1 to rotatably connect the movable plate 200 with the second pivot portion 112, and the second pivot shaft 25 can be withdrawn from the second mounting hole 1121 along the first axis L1 to disconnect the second pivot portion 112 from the movable plate 200. Therefore, the assembly and disassembly of the movable plate 200 from the first pivot portion 111 can be easily accomplished by telescopically extending or moving the second pivot shaft 25.

[0089] For example, in actual use, the first pivot portion 111 may be provided with a first mounting hole 1111, and the first pivot shaft 24 may be telescopically disposed on the movable plate 200 and protrude from the first side surface 231; and the second pivot portion 112 may be provided with a second mounting hole 1121, and the second pivot shaft 25 may be telescopically disposed on the movable plate 200 and protrude from the second side surface 232.

[0090] Therefore, when the movable plate 200 needs to be disassembled, the first pivot shaft 24 and the second pivot shaft 25 can be driven to retract inward toward the movable plate 200 at the same time, so that the first pivot shaft 24 exits the first mounting hole 1111, thereby releasing the rotational connection between the movable plate 200 and the first pivot part 111, and the second pivot shaft 25 exits the second mounting hole 1121, thereby releasing the rotational connection between the movable plate 200 and the second pivot part 112.

[0091] Conversely, when the movable plate 200 is installed between the first pivot portion 111 and the second pivot portion 112, the first pivot shaft 24 can extend to insert into the first mounting hole 1111, thereby enabling the movable plate 200 to be rotatably connected to the first pivot portion 111, and the second pivot shaft 25 can extend to insert into the second mounting hole 1121, thereby enabling the movable plate 200 to be rotatably connected to the second pivot portion 112.

[0092] The technical solution of the embodiments of this application will be described below in conjunction with the structure of the drive device 400 driving the movable plate 200.

[0093] Please continue to refer to this. Figure 5In some embodiments, the infant care device further includes a rotating arm 500, one end of which is movably mounted to a movable plate 200, and the other end of which is connected to a drive device 400. The drive device 400 drives the rotating arm 500 to rotate, so that the rotation of the rotating arm 500 can drive the movable plate 200 to rotate around a first axis L1. Furthermore, the drive device 400 can use the rotating arm 500 as a transmission component to drive the movable plate 200 to rotate around the first axis L1 from the outer periphery of the movable plate 200.

[0094] For example, the movable plate 200 is provided with a first connecting structure, and the rotating arm 500 is provided with a second connecting structure. One of the first connecting structure and the second connecting structure includes a slide groove 234, and the other includes a slider 51. The slide groove 234 extends in a direction parallel to the first axis L1, and the slider 51 is slidably connected to the slide groove 234.

[0095] Therefore, when the drive device 400 drives the rotating arm 500 to rotate, the second connecting structure of the rotating arm 500 can slide in a direction parallel to the first axis L1, so that the sliding of the second connecting structure drives the first connecting structure and the movable plate 200 to rotate around the first axis L1.

[0096] In some embodiments, the first connecting structure may include a slide 234, that is, the slide 234 may be provided on the movable plate 200, thereby utilizing the large space around the movable plate 200 to provide a sufficiently long slide 234 to meet the rotation angle requirements of the movable plate 200.

[0097] For example, a groove 234 is provided on the movable plate 200, and the opening of the groove 234 is located on the peripheral surface of the movable plate 200. Therefore, the rotating arm 500 can also be connected to the movable plate 200 from its outer peripheral side, so that both the drive device 400 and the rotating arm 500 are located on the outer peripheral side of the movable plate 200. Correspondingly, the lower surface of the movable plate 200 does not need to be provided with the rotating arm 500 and the structure connected to the rotating arm 500, thereby simplifying the structure of the lower surface of the movable plate 200 and facilitating cleaning and disinfection.

[0098] In some embodiments, the slider 51 is also detachably slidably connected to the groove 234. This allows the movable plate 200 to be easily removed and disinfected independently.

[0099] For example, the slider 51 is plugged into the slide groove 234 so that the slider 51 can be inserted into the slide groove 234 to form a sliding connection, and the slider 51 can be pulled out from the slide groove 234 to release the connection between the slider 51 and the slide groove 234, thereby contacting the connection between the rotating arm 500 and the movable plate 200.

[0100] Therefore, when the movable plate needs to be cleaned and disinfected, the first pivot shaft 24 and the second pivot shaft 25 can be driven to retract inward to release the connection between the movable plate 200 and the support assembly 100; then, the movable plate 200 can be moved away from the rotating arm 500 so that the sliding member 51 can be separated from the slide groove 234, and the movable plate 200 can be removed.

[0101] Please continue to refer to this. Figure 6 In some embodiments, the peripheral surface of the slider 51 includes a first annular surface 511, a second annular surface 512, and a third annular surface 513, which are arranged sequentially along the direction H1 in which the slider 51 is inserted into the groove 234. During the rotation of the rotating arm 500, the slider 51 can form a sliding connection by abutting against the groove wall of the groove 234 through at least one of the first annular surface 511, the second annular surface 512, and the third annular surface 513. The outer diameter of the first annular surface 511 and / or the third annular surface 513 gradually decreases along the direction away from the second annular surface 512.

[0102] For example, when the movable plate 200 is in a horizontal state, the groove opening of the slide 234 faces the horizontal direction. At this time, the slider 51 moves in the horizontal direction to insert into the slide 234, and then the second annular surface 512 simultaneously abuts against the upper and lower sidewalls of the slide 234 to form a sliding connection.

[0103] When the rotating arm 500 rotates to drive the end of the movable plate 200 with the groove 234 to flip upward from the horizontal state, the upper side wall of the groove 234 abuts against the third annular surface 513, and the lower side wall of the groove 234 abuts against the first annular surface 511 to form a sliding connection.

[0104] When the rotating arm 500 rotates to drive the movable plate 200 with the groove 234 to flip downward from the horizontal state, the lower side wall of the groove 234 abuts against the third annular surface 513, and the upper side wall of the groove 234 abuts against the first annular surface 511 to form a sliding connection.

[0105] Thus, by gradually reducing the outer diameter of the first annular surface 511 and / or the third annular surface 513, the sliding member 51 can form a stable and reliable sliding connection with the inner wall of the groove 234 during the rotation of the rotating arm 500, thereby improving the stability and reliability of the movement of the movable plate 200.

[0106] In some embodiments, the second annular surface 512 can be a cylindrical surface, so that when the movable plate 200 is in a horizontal state, the upper and lower groove walls of the slide groove 234 can form a large contact area between the second annular surface 512 to improve the stability of the sliding connection.

[0107] In some embodiments, the first annular surface 511 and the third annular surface 513 are conical surfaces. Thus, when the movable plate 200 is in an inclined state, the upper and lower groove walls of the slide groove 234 can form a large contact area with the first annular surface 511 and the third annular surface 513, respectively, to improve the stability of the sliding connection.

[0108] In some embodiments, the slope or taper of the first toroidal surface 511 and the third toroidal surface 513 may be the same.

[0109] Optionally, the generatrices of the first toroidal surface 511 and the third toroidal surface 513 can also be arc-shaped, and this embodiment of the application does not limit this.

[0110] Please refer to this as well. Figure 5 and Figure 7 In some embodiments, the rotating arm 500 may further include a rod 52. The rod 52 is driveably connected to the drive device 400 so that the drive device 400 can drive the rod 52 to rotate about a second axis L2, which is perpendicular to the first axis L1. A slider 51 is mounted on the rod 52 relative to the second axis L2, so that the drive device 400 can drive the rod 52 to rotate about the second axis L2. The rotation of the rod 52 about the second axis L2 can drive the slider 51 to perform a circular motion about the second axis L2. Finally, while the slider 51 is performing a circular motion about the second axis L2, it also slides in the slide groove 234 to drive the movable plate 200 to rotate about the first axis L1.

[0111] It should be noted that the second axis L2 is perpendicular to the first axis L1. This can be either the second axis L2 and the first axis L1 are coplanar and perpendicular, or the second axis L2 and the first axis L1 are non-coplanar and perpendicular. This application does not limit this.

[0112] For example, the rod 52 may include a first segment 521, a second segment 522, and a third segment 523. The first segment 521 extends along the second axis L2 and is connected to the output end of the drive device 400 so that the drive device 400 can drive the first segment 521 to rotate about the second axis L2. The second segment 522 is bent and connected to the first segment 521. The third segment 523 is bent adjacent to the second segment 522 so that the third segment 523 is eccentrically positioned relative to the second axis L2. A slider 51 is mounted on the end of the third segment 523 away from the second segment 522, thereby making the slider 51 eccentrically positioned relative to the second axis L2.

[0113] Therefore, the rotating arm 500 and the drive device 400 can both be located on the outer periphery of the movable plate 200 to avoid the rotating arm 500 obstructing the lower surface of the movable plate 200, thereby facilitating the cleaning and disinfection of the lower surface of the movable plate 200.

[0114] In some embodiments, the movable plate 200 is disposed with one side edge of the drive device 400 extending along the length direction of the drive device 400 in the circumferential direction.

[0115] For example, as mentioned above, the drive unit 400 extends along the third side 233 in its length direction. Therefore, compared to the drive unit 400 being perpendicular to the third side 233, this avoids the drive unit 400 protruding too far from the side of the movable plate 200 containing the third side 233, allowing for a more compact structure of the baby care device on the side of the movable plate 200 containing the third side 233, thus facilitating the miniaturization design of the baby care device.

[0116] In some embodiments, the rotation axis of the rotating arm 500 (i.e., the second axis L2) intersects the length direction of the drive device 400. Therefore, it can also be understood that the drive device 400 is not set perpendicular to the peripheral surface of the movable plate 200, so as to avoid the drive device 400 protruding too far from the peripheral surface of the movable plate 200, thereby facilitating the miniaturization design of the infant care equipment.

[0117] In some embodiments, the drive unit 400 includes a motor 41 and a reducer 42. The output end of the motor 41 is connected to the input end of the reducer 42, which is a reducer 42 with a self-locking structure to limit the rotation angle of the drive unit 400 driving the movable plate 200 to rotate about the first axis L1. Thus, the self-locking structure of the reducer 42 can prevent the movable plate 200 and the bed assembly 300 mounted on the movable plate 200 from having an excessively large tilt angle relative to the horizontal plane, which could cause the baby on the bed assembly 300 to slip off, thereby improving the integrity of the infant care equipment.

[0118] For example, the reducer 42 can be a worm gear reducer 42, which may include a worm gear reducer 42, so that the worm acts as a self-locking structure to limit the angle of rotation of the movable plate 200 driven by the drive device 400 around the first axis L1. Of course, the reducer 42 can also be any other reducer 42 with a brake self-locking structure, and this application embodiment does not limit it in this way.

[0119] In some embodiments, the drive unit 400 is configured to drive the movable plate 200 to rotate to a maximum tilt angle of 20° relative to the horizontal plane, thereby preventing the baby on the bed assembly 300 from slipping off due to excessive tilt of the movable plate 200 and the bed assembly 300 mounted on the movable plate 200 relative to the horizontal plane, thus improving the integrity of the baby care equipment.

[0120] Specifically, the drive unit 400 is configured to drive the movable plate 200 to rotate to a maximum tilt angle of 15° relative to the horizontal plane.

[0121] like Figure 4 As shown, the infant care equipment also includes a second sensor 61, which is mounted on the movable plate 200 or the bed assembly 300 to detect the tilt degree of the movable plate 200 or the bed assembly 300. This allows for accurate control of the drive device 400 based on the tilt degree of the movable plate 200 or the bed assembly 300, and prevents the movable plate 200 and the bed assembly 300 mounted on it from having an excessively large tilt angle relative to the horizontal plane, thus preventing the infant from slipping off the bed assembly 300 and improving the safety of the infant care equipment. The tilt degree here can refer to a tilt angle; or it can refer to a position or position range, which is not limited in this embodiment.

[0122] The second sensor 61 may include an angle sensor, a gyroscope, etc., and this application embodiment does not limit it.

[0123] Please continue to refer to this. Figure 8 In some embodiments, the infant care device further includes a first sensor 62. The first sensor 62 is used to detect the degree of rotation of the rotating arm 500.

[0124] Therefore, the first sensor 62 can detect the degree of rotation of the rotating arm 500, so as to accurately determine the degree of rotation of the movable plate 200 and the bed assembly 300 installed on the sliding part; of course, it can also facilitate the drive device 400 to accurately control the motion state of the rotating arm 500 based on the detection result of the first sensor 62.

[0125] It should be noted that the degree of rotation of the rotating arm 500 may include the angle of rotation of the rotating arm 500 (or the travel distance of the rotating arm 500), the position of the rotating arm 500 (or the current position of the rotating arm 500), etc., which are not limited in this embodiment.

[0126] It is also understood that the first sensor 62 may include a photoelectric sensor or a Hall sensor, but this application embodiment does not limit this.

[0127] Below, this application will use the first sensor 62 to detect the degree of rotation of the rotating arm 500 as an example to illustrate the technical solution of this application.

[0128] The infant care device may also include a detection element 700, which is mounted on the output shaft of the rotating arm 500 or the drive device 400, so that the detection element 700 can rotate synchronously with the rotating arm 500. The detection element 700 is provided with a trigger part 71, and multiple first sensors 62 are located on the rotation path of the trigger part 71. Furthermore, the angle and / or position of the rotation of the trigger part 71 can be detected by the multiple first sensors 62, so as to determine the degree of rotation of the rotating arm 500.

[0129] In some embodiments, the first sensor 62 is mounted on the drive unit 400, and the detection element 700 is located at one end of the rotating arm 500 near the drive unit 400. Thus, the first sensor 62 can be integrated into the drive unit 400, making the structure of the infant care device of the drive unit 400 more compact, while also avoiding the difficulty in cleaning and disinfecting the lower surface of the movable plate 200 caused by placing the first sensor 62 on the lower surface of the movable plate 200.

[0130] In some embodiments, the trigger portion 71 is arc-shaped. The detection element 700 may also include a connecting portion 72, one end of which is fixedly mounted to the output shaft of the rotating arm 500 or the drive device 400, and the other end of which is connected to the trigger portion 71, for example, the other end of which is connected to the middle of the trigger portion 71.

[0131] In some embodiments, at least three first sensors 62 are spaced apart on the rotation path of the trigger 71. Along the rotation direction of the rotating arm 500, the arc length of the trigger 71 is greater than or equal to the distance between any two adjacent first sensors 62, so that at least two adjacent first sensors 62 can detect the trigger 71 simultaneously.

[0132] For example, at least three first sensors 62 may include a first sub-sensor 621, a second sub-sensor 622, and a third sub-sensor 623. The first sub-sensor 621, the second sub-sensor 622, and the third sub-sensor 623 are arranged sequentially along the rotation path of the trigger 71.

[0133] When the movable plate 200 is in a horizontal state, the triggering part 71 can be located between the first sub-sensor 621 and the third sub-sensor 623, so that the triggering part 71 triggers the second sub-sensor 622, but does not trigger the first sub-sensor 621 and the third sub-sensor 623.

[0134] When the rotating arm 500 rotates forward to drive the movable plate 200 to flip upward near one end of the rotating arm 500, the triggering part 71 can move to trigger one of the first sub-sensor 621 and the third sub-sensor 623 as well as the second sub-sensor 622.

[0135] Conversely, when the rotating arm 500 reverses to drive the movable plate 200 to flip downwards near one end of the rotating arm 500, the triggering part 71 can move to trigger another of the first sub-sensor 621 and the third sub-sensor 623, as well as the second sub-sensor 622.

[0136] Furthermore, by moving the trigger unit 71 from a state that only triggers the second sub-sensor 622 to a state that simultaneously triggers the first sub-sensor 621 and the second sub-sensor 622, or switching to a state that simultaneously triggers the third sub-sensor 623 and the second sub-sensor 622, the rotation direction of the rotating arm 500 can be determined, so as to avoid the driving device 400 driving the rotating arm 500 to rotate in the wrong direction.

[0137] For example, the first sub-sensor 621, the second sub-sensor 622, and the third sub-sensor 623 are arranged in a clockwise direction:

[0138] In the initial state, the movable plate 200 and the bed assembly 300 mounted on the movable plate 200 are in a horizontal state, and at this time the triggering unit 71 only triggers the second sub-sensor 622.

[0139] When the movable plate 200 and the bed assembly 300 mounted on the movable plate 200 need to be rotated to an inclined state, the triggering part 71 can rotate counterclockwise so that the triggering part 71 simultaneously triggers the first sub-sensor 621 and the second sub-sensor 622, but does not trigger the third sub-sensor 623; then, the triggering part 71 can continue to rotate until only the first sub-sensor 621 is triggered, at which point the drive device 400 drives the rotating arm 500 and the triggering part 71 to the limit stroke position in the counterclockwise direction.

[0140] Of course, when the movable plate 200 and the bed assembly 300 mounted on the movable plate 200 need to be rotated to an inclined state, the triggering part 71 can also rotate clockwise so that the triggering part 71 triggers the third sub-sensor 623 and the second sub-sensor 622 at the same time, without triggering the first sub-sensor 621; then, the triggering part 71 can continue to rotate until only the third sub-sensor 623 is triggered, at which time the drive device 400 drives the rotating arm 500 and the triggering part 71 to the limit stroke position in the clockwise direction.

[0141] Please continue to refer to this. Figure 9 In some embodiments, the infant care device further includes a human-machine interface 82 and a processor 81. The human-machine interface 82 is used to receive user pressing operations, and the processor 81 is configured to control the drive device 400 based on the pressing operations. Thus, the user can conveniently control the drive device 400 through the human-machine interface 82 to adjust the tilt of the movable plate 200 and the bed assembly 300 mounted on the movable plate 200.

[0142] The human-computer interaction component 82 may include buttons for accepting user press operations. The buttons may be physical buttons or virtual buttons on a touchscreen; this embodiment does not limit the specific type of button used.

[0143] In some embodiments, the processor 81 is configured to: accept a first press operation by a user pressing the human-machine interface component 82, the first press operation being used to control the drive device 400 to drive the movable plate 200 to rotate in a target direction; if the movable plate 200 is located at the limit travel position in the target direction, then the drive device 400 is not controlled to drive the movable plate 200 to rotate.

[0144] Furthermore, this avoids situations where the drive unit 400 continues to work after the movable plate 200 is at its limit travel position in the target direction, resulting in excessive power consumption of the baby care equipment or damage caused by interference between the parts of the baby care equipment.

[0145] In some embodiments, the processor 81 is configured to: accept a second press operation by a user pressing the human-machine interface component 82, the second press operation being used to control the drive device 400 to drive the movable plate 200 to rotate toward a target angle; if the movable plate 200 is at the target angle, then the drive device 400 is not controlled to drive the movable plate 200 to rotate.

[0146] This avoids situations where the drive device 400 continues to work after the movable plate 200 is at the target angle, resulting in excessive power consumption of the baby care equipment or incorrect angle of the movable plate 200.

[0147] For example, the buttons of the human-computer interaction component 82 may include a clockwise rotation button, a counterclockwise rotation button, and a leveling button. The clockwise rotation button is used to control the drive device 400 to drive the movable plate 200 to rotate clockwise, the counterclockwise rotation button is used to control the drive device 400 to drive the movable plate 200 to rotate counterclockwise, and the leveling button is used to control the drive device 400 to drive the movable plate 200 to rotate to a horizontal position. Therefore, the first pressing operation can be the user pressing the clockwise or counterclockwise rotation button, and the second pressing operation can be pressing the leveling button.

[0148] Therefore, when the user presses and holds the clockwise rotation button, if the movable plate 200 is at its maximum clockwise rotation stroke, the drive device 400 will not operate; if the movable plate 200 is not at its maximum clockwise rotation stroke, the drive device 400 will drive the movable plate 200 to rotate clockwise to its maximum stroke stroke and then stop. During the rotation of the movable plate 200, the user can release the clockwise rotation button at any time to stop the drive device 400 from driving the movable plate 200 to rotate clockwise.

[0149] Similarly, when the user presses and holds the counter-clockwise rotation button, if the movable plate 200 is at its maximum counter-clockwise rotation position, the drive device 400 will not operate; if the movable plate 200 is not at its maximum counter-clockwise rotation position, the drive device 400 will drive the movable plate 200 to rotate counter-clockwise to its maximum position and then stop. During the rotation of the movable plate 200, the user can release the counter-clockwise rotation button at any time to stop the drive device 400 from driving the movable plate 200 to rotate counter-clockwise.

[0150] When the user presses the leveling button, if the movable plate 200 is in a horizontal state, the drive device 400 will not work; if the movable plate 200 is not in a horizontal state, the drive device 400 will be controlled to drive the movable plate 200 to rotate to a horizontal state.

[0151] In some embodiments, the processor 81 is configured to: receive a third press operation from the user pressing the human-machine interface component 82, control the drive device 400 to drive the movable plate 200 to rotate around the first axis L1; when the drive device 400 drives the movable plate 200 to rotate to a first preset angle according to the third press operation, control the drive device 400 to stop driving the movable plate 200 to rotate; when the drive device 400 stops driving the movable plate 200 to rotate to the first preset angle, if the user does not stop the third press operation within a first preset time period, or if the third press operation from the user is received again, control the drive device 400 to drive the movable plate 200 to rotate again.

[0152] It is understandable that the first preset angle can be a commonly used angle for the movable board 200 and the bed assembly 300 on the movable board 200 during the infant care process, so that the movable board 200 can be directly suspended at the first preset angle or suspended at the first preset angle for a first preset time during the user's control of the movement and rotation, thereby avoiding the user's inability to accurately control the movable board 200 to be suspended at the first preset angle.

[0153] For example, the first preset angle can be the angle at which the movable plate 200 is in a horizontal state, and the first preset duration can be 1-10 seconds. Correspondingly, the buttons of the human-machine interface component 82 can include clockwise rotation buttons and counterclockwise rotation buttons. The clockwise rotation button is used to control the drive device 400 to drive the movable plate 200 to rotate clockwise, and the counterclockwise rotation button is used to control the drive device 400 to drive the movable plate 200 to rotate counterclockwise. The third pressing operation is when the user presses either the clockwise or counterclockwise rotation button.

[0154] Therefore, during the process of the user pressing and holding the clockwise rotation button, firstly, the drive device 400 stops working after the movable plate 200 rotates to a horizontal state; then, if the user does not release the clockwise rotation button within the first preset time period, or when the user presses the clockwise rotation button again, the drive device 400 drives the movable plate 200 to continue rotating clockwise.

[0155] Similarly, during the process of the user pressing and holding the counterclockwise rotation button, firstly, when the movable plate 200 rotates to a horizontal position, the drive device 400 stops working; then, if the user does not release the counterclockwise rotation button within the first preset time period, or when the user presses the counterclockwise rotation button again, the drive device 400 drives the movable plate 200 to continue rotating counterclockwise.

[0156] Therefore, it can be seen that the movable plate 200 can be precisely hovered in a horizontal state by using two buttons: clockwise rotation button and counterclockwise rotation button, so there is no need to add a leveling button.

[0157] Of course, in some other implementations, the drive device 400 can start working when the user presses the button and stop working when the user stops pressing the button, so that the user can control the drive device 400 in real time based on the angle of the movable plate 200 and the bed assembly 300 on the movable plate 200.

[0158] Please continue to refer to this. Figure 10 In some embodiments, the support assembly 100 may include a housing 11. The inner wall of the housing 11 has a first pivot portion 111 and a second pivot portion 112, so that the movable plate 200 can be rotatably mounted on the housing 11.

[0159] In some embodiments, the support assembly 100 may further include a column 12, which is connected and fixed to the housing 11. The infant care equipment also includes a functional component 900 mounted on the column to be erected on the upper side of the housing 11 in the vertical direction. The functional component 900 may include a protective cover, a lighting assembly, a temperature control assembly, a physiological parameter detection assembly, etc. The temperature control assembly is used to regulate the temperature at the bed assembly, for example, the temperature control assembly may be used to radiate heat energy to the bed assembly assembly, etc. The physiological parameter detection assembly is used to detect the parameters of the infant carried by the bed assembly 300, such as the infant's body surface temperature, etc., which are not limited in this application embodiment.

[0160] The functional component 900 may include only one of the protective cover, lighting component, temperature control component and physiological parameter detection component, or it may include at least two of the protective cover, lighting component, temperature control component and physiological parameter detection component. This application embodiment does not limit this.

[0161] In some embodiments, the support assembly 100 may further include a base 13, a housing 11, and / or a column mounted on the base 13. The base 13 may be a movable base 13 to facilitate the movement of the baby care equipment on the base 13; for example, the base 13 may be equipped with casters, etc.
