DETAILED DESCRIPTION OF THE INVENTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0030] Embodiment

[0031] Combined with Figures 1 to 9 , this embodiment provides a new type of rhythmic bed, including a base 1 and a bed frame 2. The base 1 is provided with a driving device 3, the bed frame 2 is arranged on the base 1, and the driving device 3 is used to provide power so that the bed frame 2 can linearly displace reciprocally relative to the base 1.

[0032] Among them, the bed frame 2 includes a backrest part 4, a seat cushion part 5, and a leg board part 6. The seat cushion part 5 is rotatably arranged on the base 1 and can be freely switched between a horizontal placement state and an upward inclination state under the drive of a first actuator 7. The leg board part 6 is pivotally connected to one end of the seat cushion part 5 and can freely swing relative to the seat cushion part 5 under the drive of a second actuator 8. The backrest part 4 is pivotally connected to the other end of the seat cushion part 5 and can freely swing relative to the seat cushion part 5 under the drive of a third actuator 9.

[0033] In the prior art, the rhythmic exercise equipment on the market is generally vertical. When in use, the user stands on the rhythmic exercise equipment, and the rhythmic exercise equipment drives the human body to vibrate in the vertical direction to achieve the exercise effect. However, the bed frame 2 of the rhythmic bed is usually set as an integral bed board or frame body, which is difficult to effectively adapt and adjust the sitting and lying postures of the user, especially when sitting, it cannot ensure the comfortable use of the user.

[0034] In response to this, for the above-mentioned new type of rhythmic bed, through the relatively independent adjustment of the seat cushion part 5, the backrest part 4, and the leg board part 6 of the bed frame 2, the user can adjust the use position according to personal needs, so as to adapt to different sitting and lying postures, greatly improving the comfort and experience. In particular, the seat cushion part 5 can be freely switched between horizontal placement and upward inclination, and the backrest part 4 and the leg board part 6 can also swing independently, significantly improving the flexible adjustment of the entire bed frame 2 and meeting diverse use requirements.

[0035] Among them, the cooperation between the driving device 3 and multiple actuators enables the bed frame 2 to easily perform reciprocating displacement and angle adjustment of each independent part without manual force, which is convenient to use, reduces the complexity of operation, is not limited to the traditional lying function, and can be adjusted to an angle suitable for sitting according to needs, providing a flexible use experience for activities such as reading, watching TV, and recovering and resting, and can provide personalized adjustment for different users. Especially for the elderly, patients in the recovery period or patients who have been bedridden for a long time, it can bring better comfort and health support.

[0036] Moreover, through the rhythmic displacement and angle adjustment, it helps to reduce the pressure points of the body during static sleep and promote blood circulation, which is especially beneficial to people who have been bedridden or sitting still for a long time.

[0037] As Figure 2 and Figure 3 shown, in this embodiment, the base 1 is provided with a hinge frame 10, and the seat part 5 and the backrest part 4 are coaxially pivotally connected to the hinge frame 10 correspondingly. On the one hand, by coaxially pivotally connecting the seat part 5 and the backrest part 4 to the hinge frame 10, it can ensure that the two components remain balanced and stable during movement, avoiding unnecessary shaking or offset, thereby improving the overall reliability of the bed frame 2. On the other hand, the coaxial pivotal connection makes the angle adjustment of the seat part 5 and the backrest part 4 smoother and more natural, reduces mechanical friction, and improves the use experience. When the user adjusts the posture of the bed frame 2, they will not feel stuck or unsmooth, and the operation is more fluent.

[0038] In addition, combining the seat part 5 and the backrest part 4 with the hinge frame 10 in a coaxial pivotal connection manner helps to simplify the overall structure of the bed frame 2, avoid complex structural connections, make the occupied space of the rhythmic bed smaller, and the overall design more concise and compact.

[0039] Furthermore, a support frame 11 is correspondingly provided on the base 1, and the rotation axis defined by the support frame 11 and the hinge frame 10 are horizontally opposed to each other to stably limit the seat part 5 in a horizontal placement state. Thus, through the support frame 11, the situation that the seat part 5 tilts or becomes unstable during use is further effectively avoided, improving the stability and safety of the bed frame 2. And the connection between the seat part 5 and the support frame 11 is more firm and stable, which can effectively share the gravity of the seat part 5 after angle adjustment, prevent the bed frame 2 from deforming or loosening due to uneven load, and extend the service life.

[0040] In this embodiment, a limiting member is correspondingly provided on the base 1, and the limiting member is configured such that the backrest portion 4 in an inclined state can be quickly limited to its horizontal state after swinging. Thus, through the limiting member, it is possible to ensure that the backrest portion 4 can be accurately and quickly switched between the inclined state and the horizontal state. When the backrest portion 4 rotates from the inclined state to the horizontal state, the limiting member can quickly position and stabilize the position of the backrest portion 4, ensuring that any conversion can be accurately in place, and avoiding the problems of inaccurate angles or position offsets that may exist when the traditional hospital bed converts angles.

[0041] Specifically, the limiting member includes a support tray 12 (as Figure 3 shown). The support tray 12 is used to abut against the backrest portion 4 rotated to the horizontal state. When the backrest portion 4 rotates to the horizontal state, the support tray 12 provides precise contact and support for it, which can not only ensure that the angle of the backrest portion 4 is stably fixed in the horizontal state, but also prevent the backrest portion 4 from accidentally moving or swinging due to external forces or its own weight, etc. Moreover, the support tray 12 effectively avoids the situation where the backrest portion 4 is not fully fixed, thereby ensuring the stability of the bed frame 2.

[0042] In addition, the support tray 12 realizes limit locking by contacting the backrest portion 4. Compared with the traditional mechanical locking device, this way of contact support makes the limiting process simpler and more efficient, and at the same time achieves the purpose of efficient support.

[0043] Furthermore, at least two support trays 12 are provided, which are respectively used to abut against the back edge of the backrest portion 4. Thus, the two support trays 12 respectively abut against the back edge of the backrest portion 4, which can provide more balanced support force. Compared with a single support tray 12, the two trays are distributed on both sides of the backrest portion 4, which can effectively disperse the gravity load of the backrest portion 4, avoid tilting or instability caused by concentration on one side, and thus further improve the stability of the entire bed frame 2.

[0044] Preferably, rubber pads 13 are provided on the end faces of the support trays 12. The rubber pads 13 can effectively reduce the wear or damage to the surface of the backrest portion 4 when the support trays 12 contact the backrest portion 4. And it provides a certain amount of friction to prevent the support trays 12 from sliding or shifting when contacting the backrest portion 4. It also has a certain shock-absorbing effect. When the support trays 12 contact the backrest portion 4, it can effectively absorb part of the impact force and reduce the vibration or noise generated during the adjustment process. Preferably, the rubber pads 13 are soft, which can provide a softer and milder support for the backrest portion 4, avoiding the discomfort caused by direct contact of hard materials with the back.

[0045] In this embodiment, the first actuator 7 is configured as an inclined push rod. The inclined push rod is obliquely arranged on the base 1 and connected to the seat portion 5 near the leg plate portion 6, and its output shaft is hinged on the seat portion 5 to flexibly switch states. Specifically, one end of the inclined push rod is fastened to the base 1, and the other end is hinged to the seat portion 5, and it has an inclined angle relative to the base 1, so that the seat portion 5 can be smoothly and flexibly switched between the horizontal placement state and the upward inclined state. Due to the inclined setting of the inclined push rod, a large angle range and adjustment flexibility are provided, meeting the needs of different users in various activities. Preferably, the inclined angle of the inclined push rod is between 30° and 60°.

[0046] In this embodiment, the second actuator 8 is configured as a straight push rod. The straight push rod is horizontally arranged on the base 1, and its output shaft is hinged to the leg plate portion 6. Obviously, the straight push rod is used to provide a stable linear driving force, so that the leg plate portion 6 can swing freely within a preset range according to the user's needs, ensuring the smoothness and comfort of the adjustment process.

[0047] In this embodiment, the third actuator 9 includes a rotating member 14 and a piston rod 15. The rotating member 14 is arranged on the base 1, the output shaft of the piston rod 15 is hinged to the backrest portion 4, and the rotating member 14 drives the piston rod 15 to rotate for free telescopic movement. Among them, by driving the piston rod 15 to rotate through the rotating member 14, the backrest portion 4 can be flexibly adjusted in angle, and the piston rod 15 can telescopically move freely, so as to realize the effective adjustment of the backrest portion 4, thereby providing greater flexibility and adjustment range, so that the backrest portion 4 can smoothly transition from one position in the inclined state to another position in the inclined state, or to the position in the horizontal state, avoiding excessive violent displacement and improving the comfort of the user.

[0048] As Figures 4 to 9 shown, in this embodiment, the backrest portion 4 swings within an acute angle range, and it has a lower limit threshold for swinging downward to the horizontal state. The seat portion 5 swings within an acute angle range, and it has a lower limit threshold for swinging downward to the horizontal state. The leg plate portion 6 swings within an acute angle range, and it has an upper limit threshold for swinging upward to the horizontal state. Thus, by defining the lower limit threshold or the upper limit threshold, the swing is prevented from exceeding a reasonable adjustment range. In particular, the swing within the acute angle range can ensure that the movement range of each component does not exceed the safe load range, not only avoiding structural overload, but also maintaining the balance and stability of each component.

[0049] Furthermore, the bed frame 2 has a normal use position, a flat use position, and a folded use position.

[0050] When in the normal use position, the seat cushion is in a horizontal placement state, the backrest portion 4 is in an inclined state, and the leg rest portion 6 is in an inclined state or a horizontal state. At this time, it is more conducive to the user's sitting and standing use in the normal use position, and the leg rest portion 6 can be selectively lifted to the horizontal or inclined and lowered.

[0051] When in the flat use position, the backrest portion 4 is in a horizontal state, the seat cushion portion 5 is in a horizontal placement state or an upwardly inclined state, and the leg rest portion 6 is in an inclined state or a horizontal state. Among them, when the backrest portion 4, the seat cushion portion 5, and the leg rest portion 6 are all in a horizontal state, it is conducive to the user lying straight directly for use. In particular, when the backrest portion 4 is in a horizontal state, the seat cushion portion 5 is in an inclined state, and the leg rest portion 6 is in a horizontal state, the frame at this time can place the user in a zero-gravity use state, greatly improving the user experience.

[0052] When in the reclined use position, the backrest portion 4 is in an inclined state, the seat cushion portion 5 is in an upwardly inclined state, and the leg rest portion 6 is in an inclined state. Thus, when the backrest portion 4, the seat cushion portion 5, and the leg rest portion 6 are all in an inclined state, the user can use it in a reclined state, making the use more diverse.

[0053] It should be noted that the driving device 3 is a rhythm mechanism. The base 1 includes a bracket 16 and a rhythm frame 17. The rhythm mechanism is power-connected to the rhythm frame 17 and is used to drive the rhythm frame 17 to reciprocate in the vertical direction relative to the support frame 11. The cooperation of the rhythm mechanism and its rhythm frame 17 are all structures of rhythm instruments in the prior art, so no further description will be given here.

[0054] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention.
