[0003] In order to solve the above technical problems, one of the objectives of the present invention is to provide a movable reclining chair with a simple structure and a high degree of automation.

[0004] To achieve the above objective, the technical solution of the present invention is as follows: A movable reclining chair includes a first traveling mechanism and a reclining board assembly. The reclining board assembly includes a first board body, a second board body, and a third board body that are horizontally arranged and distributed in sequence. Both ends of the second board body are rotatably connected to the first board body and the third board body respectively. A first electric driving member is provided at the rotational connection between the second board body and the first board body, and the first electric driving member is used to drive the first board body to rotate downward to face downward or upward to be horizontal. A second electric driving member is provided at the rotational connection between the second board body and the third board body, and the second electric driving member is used to drive the third board body to rotate upward to face upward or downward to be horizontal. The first traveling mechanism is installed at the lower end of the second board body, and it is used to drive the reclining board assembly to move.

[0005] The beneficial effect of the above technical solution is that: Through the first electric driving member and the second electric driving member, the first board body, the second board body, and the third board body can all be horizontal. In this way, the three can be combined together to form a horizontal bed board, and a person can lie on it. When the second electric driving member drives the third board body to rotate upward to be vertically upward, at this time, the third board body can be used as a backrest, the second board body can be used as a seat board, and the first board body is used to rest the legs. At this time, if the first electric driving member drives the first board body to rotate to be vertically downward, at this time, the person's calves can droop, and the person is in a sitting position as a whole. And the first traveling mechanism can flexibly drive the person on the reclining board assembly to move. At this time, the person can lie or sit on the reclining board assembly.

[0006] In the above technical solution, an electric rotary driving member is further provided at the upper end of the first traveling mechanism, and it is connected to the lower end of the second board body through the electric rotary driving member. The electric rotary driving member is used to drive the reclining board assembly to rotate in the horizontal plane.

[0007] The beneficial effect of the above technical solution is that: In this way, the reclining board assembly can rotate flexibly on the first traveling mechanism to adjust its direction.

[0008] In the above technical solution, the first traveling mechanism is an electric crawler chassis.

[0009] The beneficial effects of the above technical solution are as follows: It has good stability, can adapt to complex road conditions, is not prone to slipping when braking, and can turn in place.

[0010] The above technical solution further includes a first power module and a first control module. The first electric drive member, the second electric drive member, the electric rotary drive member, the first traveling mechanism, and the first power module are all electrically connected to the first control module.

[0011] The beneficial effects of the above technical solution are as follows: It has a high degree of intelligence, good integration, and is flexible to adapt.

[0012] The second object of the present invention is to provide a split wheelchair with a simple structure and diverse functions.

[0013] To achieve the above object, the technical solution of the present invention is as follows: A split multifunctional wheelchair includes a moving platform and the movable reclining chair as described above. The movable reclining chair can be placed on the moving platform and is driven by the moving platform to move.

[0014] The beneficial effects of the above technical solution are that its structure is simple, the movable reclining chair is placed on the moving platform, and the third plate body is tilted upward while the first plate body rotates downward, so that the two are combined to form a wheelchair.

[0015] In the above technical solution, the moving platform includes a second traveling mechanism and two brackets. The two brackets are respectively vertically arranged on both sides of the upper end of the second traveling mechanism, and the mutually close sides of the two brackets respectively have horizontally arranged supporting plates. The two supporting plates are used to jointly support the movable reclining chair.

[0016] The beneficial effects of the above technical solution are as follows: In this way, the movable reclining chair is placed on the bed and the moving platform is on the ground. At this time, it can be directly driven so that its two crawlers are placed and braked on the two supporting plates, or the moving platform can directly move so that its two supporting plates are located below both sides of the second plate body to lift the second plate body, thereby the two are combined to form a wheelchair.

[0017] In the above technical solution, the brackets are both electric telescopic brackets. The two electric telescopic brackets are respectively installed at the front ends of both sides of the second traveling mechanism, and their telescopic ends face upward. The front end of each supporting plate is fixedly connected to the telescopic end of the corresponding electric telescopic bracket.

Detailed implementation manners

[0035] The principles and features of the present invention will be described below in conjunction with the accompanying drawings and embodiments. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0036] Embodiment 1

[0037] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides a movable recliner, which includes a first traveling mechanism 11 and a reclining board assembly 12. The reclining board assembly 12 includes a first board body 121, a second board body 122, and a third board body 123 that are horizontally arranged and distributed in sequence. Both ends of the second board body 122 are rotatably connected to the first board body 121 and the third board body 123 respectively. A first electric driving member is provided at the rotational connection between the second board body 122 and the first board body 121. The first electric driving member is used to drive the first board body 121 to rotate downward to face downward or upward to be horizontal. A second electric driving member is provided at the rotational connection between the second board body 122 and the third board body 123. The second electric driving member is used to drive the third board body 123 to rotate upward to face upward or downward to be horizontal. The first traveling mechanism 11 is installed in the middle of the lower end of the second board body 122, and it is used to drive the reclining board assembly 12 to move. By means of the first electric driving member and the second electric driving member, the first board body, the second board body, and the third board body can all be horizontal. In this way, the three can be combined together to form a horizontal bed board, and a person can lie on it. When the second electric driving member drives the third board body to rotate upward to be vertically upward, at this time, the third board body can be used as a backrest, the second board body can be used as a seat board, and the first board body is used to rest the legs. At this time, if the first electric driving member drives the first board body to rotate to be vertically downward, at this time, the person's calves can droop, and at this time, the person is in a sitting position as a whole. And the first traveling mechanism can flexibly drive the person on the reclining board assembly to move. At this time, the person can lie or recline on the reclining board assembly. Among them, the horizontal height of the first traveling mechanism should not be too high. Preferably, it can be set between 5 - 15 cm. The lengths of the first board body and the second board body can both be set between 30 - 50 cm, and the length of the third body can be set between 50 - 100 cm. Among them, the rotational connection between the second board body and the third board body and the second electric driving member can refer to the connection method between the seat board and the backrest in an electric adjustable car seat, which belongs to the prior art and will not be elaborated here. The same applies to the first board body, the second board body, and the first electric driving member, so it will not be elaborated here.

[0038] Among them, an electric rotary driving member 13 is further provided at the upper end of the first traveling mechanism 11 described in the above technical solution, and the electric rotary driving member 13 is connected to the middle of the lower end of the second board body 122. The electric rotary driving member 13 is used to drive the reclining board assembly 12 to rotate in the horizontal plane. In this way, the reclining board assembly can flexibly rotate on the first traveling mechanism to adjust its direction. Among them, the electric rotary driving member can adopt an electric turntable, which has a thin thickness and good stability.

[0039] In the above technical solution, the first traveling mechanism 11 is an electric tracked chassis, which has good stability, can adapt to complex road conditions, is not easy to slip when braking, and can turn in place.

[0040] Such as Figure 3As shown, the above technical solution further includes a first power module and a first control module. The first electric drive member, the second electric drive member, the electric rotary drive member 13, the first traveling mechanism 11 and the first power module are all electrically connected to the first control module, which has a high degree of intelligence, good integration, and is flexible to adapt to.

[0041] In this way, the entire movable recliner can be placed on the bed platform without laying cotton wadding on the bed platform, and people can directly use the reclining board assembly as the bed board. At this time, the movable recliner can move flexibly on the bed platform. Among them, preferably, soft cushion layers are provided at the upper ends of the first board body, the second board body and the third board body, so that its comfort is better.

[0042] Among them, the first power module is a storage battery, which can be integrated in the first traveling mechanism. And preferably, the rotation angle of the electric rotary drive member needs to be limited within the range of 360°, that is, its rotation range cannot exceed one circle. The first control module can be arranged on one side of the upper end of the second board body, and it has at least five buttons. Two of the buttons respectively control the operation of the first electric drive member and the second electric drive member, one button controls the operation of the electric rotary drive member, and at least two buttons control the first traveling mechanism to move forward, backward or turn.

[0043] Embodiment 2

[0044] As Figures 4 - 6 As shown, this embodiment provides a split-type multifunctional wheelchair, including a moving platform 2 and the movable recliner 1 as described in Embodiment 1. The movable recliner can be placed on the moving platform and is driven by the moving platform to move. Its structure is simple. The movable recliner is placed on the moving platform, and the third board body is tilted upward, while the first board body rotates downward, so that the two are combined to form a wheelchair.

[0045] Among them, in the above technical solution, the mobile platform 2 includes a second traveling mechanism 21 and two brackets 22. The two brackets are vertically arranged on both sides of the upper end of the second traveling mechanism, and on one side of the two brackets 22 close to each other, there are horizontally arranged supporting plates 23 (at this time, the two brackets are distributed at intervals). The two supporting plates 23 are used to jointly support the movable reclining chair 1. In this way, the movable reclining chair can be driven to place and brake its two crawlers on the two supporting plates, so that the second traveling mechanism and the movable reclining chair jointly form an electric wheelchair. For example, the movable reclining chair can be placed on the bed, and the first plate body, the second plate body and the third plate body are all kept horizontal. At this time, people can directly sleep on the reclining plate assembly. When people need to combine the movable reclining chair with the mobile platform into a wheelchair, people can control the mobile platform to move to the edge of the bed, and the rear ends of its two supporting plates are perpendicular to the edge of the bed. Then, the first electric driving member drives the first plate body to rotate downward to make people sit upright, and then the first traveling mechanism moves to place its two crawlers on the two supporting plates. At this time, the two form a wheelchair, and the second traveling mechanism drives the movable reclining chair to move flexibly. For details, please refer to Figure 8 。

[0046] In the above technical solution, the brackets 22 are all electric telescopic brackets. The two electric telescopic brackets are respectively installed at the front ends of both sides of the second traveling mechanism 21, and their telescopic ends face upward. The front end of each supporting plate 23 is fixedly connected to the telescopic end of the corresponding electric telescopic bracket. The two electric telescopic brackets expand and contract synchronously to synchronously adjust the horizontal height of the two supporting plates 23. In this way, the horizontal height of the supporting plates can be adjusted flexibly to adapt to different bed edge heights.

[0047] In the above technical solution, the second traveling mechanism 21 is an electric wheeled chassis, which is flexible in turning, convenient to operate and has good comfort.

[0048] As Figure 7 shown, in the above technical solution, the mobile platform 2 further includes a second power module, a second control module and a signal receiving module. The movable reclining chair further includes a remote control module. The second traveling mechanism 21, the second power module, the signal receiving module and the two brackets 22 are all electrically connected to the second control module. The remote control module is installed on the movable reclining chair 1 and is electrically connected to the first power module. The signal receiving module is used to receive the remote control information of the remote control module and control the working states of the second traveling mechanism 21 and the two electric telescopic brackets through the second control module. In this way, the integration of the mobile platform is higher, and at the same time, the remote control module is set on the movable reclining chair, so that the people on the movable reclining chair can flexibly remotely control the movement of the mobile platform.

[0049] Among them, the second power module is a storage battery, and the second power module, the second control module, and the signal receiving module can all be integrated into the second traveling mechanism. Among them, the remote control module can be arranged on one side of the upper end of the second plate body, and it has at least three buttons. One button is used to synchronously extend and retract the two electric telescopic brackets, and the remaining at least two buttons are used to control the second traveling mechanism to move forward, backward, or turn.

[0050] Preferably, first engaging portions are respectively provided at the front ends of the upper ends of the two pallets, and two second engaging portions that cooperate with and correspond to the first engaging portions one by one are provided at the front end of the first traveling mechanism. When the movable reclining chair moves onto the pallet, the first engaging portion and the corresponding second engaging portion are engaged to prevent the movable reclining chair from falling off the moving platform. When the movable reclining chair needs to be separated from the moving platform, only the first engaging portion and the second engaging portion need to be separated.

[0051] Among them, the first engaging portion can be a hanging ring, and the second engaging portion can be a hanging buckle. When the movable reclining chair is placed on the two pallets, the hanging buckle is hooked onto the hanging ring to limit the movable reclining chair on the two pallets.

[0052] Among them, preferably, armrests are respectively provided vertically on the sides of the two pallets away from each other, and the distance between the two armrests is slightly greater than the width of the second plate body, so that the movable reclining chair can be laterally limited by the two armrests.

[0053] Embodiment 3

[0054] Same as Embodiment 2, the difference is that, as Figures 9 - 10 shown, the telescopic end of each electric telescopic bracket is fixedly connected to the front end of the corresponding pallet, and both sides of the second plate body protrude from both sides of the first traveling mechanism. At this time, the person can control the movable reclining chair to move to the edge of the bed, and the person faces the edge of the bed. Then, control the moving platform to move closer to the edge of the bed, and adjust the height of the two pallets to be higher than the height of the bed but lower than the height of the second plate body. At this time, control the moving platform to continue moving towards the edge of the bed until the two pallets are respectively located below both sides of the second plate body and above the bed. At this time, control the bracket to extend again and the second plate body is lifted by the two pallets. At this time, the entire movable reclining chair is separated from the bed. Finally, control the moving platform to drive the movable reclining chair away from the edge of the bed, and then the bracket contracts to reduce the horizontal height of the movable reclining chair. The two are combined to form a reclining chair. When the two need to be separated, the actions are just the opposite of when they are combined.

[0055] Among them, the width of the first plate body is smaller than the width of the second plate body, and both sides of the second plate body protrude from both sides of the first plate body, and the distance between the two pallets is greater than the width of the first plate body.

[0056] Embodiment 4

[0057] Same as Embodiment 3, the difference is that, as Figure 11 shown, on the sides of the pallet that are close to each other, sliding grooves 231 are respectively recessed, and the rear ends of the sliding grooves 231 penetrate through the pallet. When the moving platform is combined with the movable recliner, the bracket of the moving platform extends to adjust the horizontal height of the two sliding grooves 231 to be exactly the same as that of the second plate body. When the moving platform continues to move closer to the movable recliner, both sides of the second plate body are respectively inserted into the two sliding grooves 231, thus completing their combination. When they need to be separated, the operation is just the opposite of their combination.

[0058] Among them, the groove width of the two sliding grooves needs to be 2-5 mm larger than the thickness of the second plate body, so as to facilitate their docking. Preferably, the front ends of the two sliding grooves are blocked, and at the same time, the groove width at the rear ends of the two sliding grooves is enlarged, so as to further facilitate the insertion of the second plate body into the sliding grooves.

[0059] Among them, the second control module, the signal receiving module and the remote control module all belong to the prior art (the principle is similar to that of the existing remote control toy car), so they will not be elaborated here. The first control module can adopt a single-chip microcomputer of the ARM series.

[0060] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
