With reference to fig. 1 and 2, the present embodiment provides a bed-tail assistant bunk bed, which includes a front bed leg 1, a rear bed leg 2, a bed frame 3 and a bed board 4, wherein the front bed leg 1 and the rear bed leg 2 are connected together through the bed frame 3, preferably, the bed frame 3 is two parallel and opposite parts which are respectively connected to two sides of the front bed leg 1 and the rear bed leg 2, the front bed leg 1 and the rear bed leg 2 can be vertically supported through the connection support of the bed frame 3, and the bed board 4 is placed on the bed frame 3, so as to form a stable bed which can be used for rest. In this embodiment, in order to omit the step of turning the elderly around in bed and fundamentally solve the problem that the waist of the elderly may be injured due to the turning of the upper body, the bed frame 3 is sleeved with the sliding table 31, sliding grooves sleeved with the bed frame 3 are formed on both sides of the sliding table 31, and the length of the sliding table 31 is smaller than that of the bed frame 3, so that the sliding table 31 can reciprocate along the bed frame 3. A first push rod 5 is arranged in the middle of the front bed leg 1, and the first push rod 5 is connected with the sliding table 31 and provides power to push the sliding table 31 to reciprocate along the bed frame 3. The bed board 4 is divided into an upper body board 41, a thigh board 42 and a shank board 43, the upper body board 41 is connected with the thigh board 42 through hinges, the thigh board 42 is connected with the shank board 43 through hinges, and the sliding table 31 is hinged with a pneumatic spring 6 and a second push rod 7 which can push the upper body board 41 and the thigh board 42 to turn over, so that the upper body board 41, the thigh board 42 and the shank board 43 are separated, bending in different degrees can be performed according to needs, and the damage to the knee of the old is reduced. In order to prevent the upper body plate 41 and the thigh plate 42 from being displaced when the pneumatic spring 6 and the second push rod 7 push the upper body plate 41 and the thigh plate 42, a pivot shaft hinged to the slide table 31 is provided at one end of the thigh plate 42 connected to the thigh plate 43, and the thigh plate 42 is fixed to the slide table 31 and can be rotated by external force. The bed plate 4 is in a state of slightly bending knees from a horizontal state to a state of slightly bending knees at the upper part through the cooperation of the telescopic motions of the first push rod 5, the pneumatic spring 6 and the second push rod 7, so that the old people can finish the action of getting off the bed from the state of lying down to the state of slightly bending knees, or the bed plate 4 is in a state of slightly bending knees at the upper part to the horizontal state, so that the old people can finish the action of getting on the bed from the state of slightly bending knees to the state of lying down.

Referring to fig. 2, preferably, the first push rod 5 may be fixed to the front legs 1 by riveting, and when the first push rod 5 is retracted to a minimum, the sliding table 31 has a certain gap from the front legs 1, so that the length of the upper body panel 41 needs to be extended forward, and the upper body panel 41 can cover the gap between the two when viewed from the top, thereby making the whole body more beautiful. Of course, it may be fixed by bolting. In another embodiment, the first pushing rod 5 can also be fixed on the sliding table 31, and the other end of the first pushing rod 5 is fixedly connected to the front bed leg 1, so that the sliding table 31 can be driven to reciprocate while the first pushing rod 5 extends and contracts.

Further, the pneumatic spring 6 and the second push rod 7 are hinged on the middle platform of the sliding table 31, and preferably, the pneumatic spring 6 and the second push rod 7 are hinged on the middle centering position of the sliding table 31, so that the overturning stress is better. The pneumatic spring 6 is connected with the upper body plate 41, the second push rod 7 is connected with the thigh plate 42, when the upper body plate 41 and the thigh plate 42 are in a horizontal state, the pneumatic spring 6 and the second push rod 7 are in a vertical state, and certainly, the pneumatic spring 6 and the second push rod 7 are not higher than the height of the pneumatic spring 6 and the second push rod 7 in the minimum state of retraction, so that the upper body plate 41 and the thigh plate 42 can be horizontally abutted against the sliding table 31, and the pneumatic spring 6 and the second push rod 7 are not supported in a horizontal state, and therefore safety of the old can be guaranteed when the old lies down. When the thigh plate 42 is pushed to turn over by the second push rod 7, the pneumatic spring 6 is driven to push the upper body plate 41 to turn over, and the pneumatic spring 6 and the second push rod 7 incline along with the connecting point of the upper body plate 41 and the thigh plate 42, so that the two are in a balanced state. Preferably, the connection point of the pneumatic spring 6 and the upper body plate 41 should be close to the front end of the upper body plate 41, and the same connection point of the second push rod 7 and the thigh plate 42 should be close to the front end of the thigh plate 42, so that the pneumatic spring 6 and the second push rod 7 can be overturned more slowly when being extended and retracted, and cannot be overturned too much to cause damage to the waist of the elderly.

Referring to fig. 2, the sliding table 31 is pushed by the first push rod 5 to slide towards the bed tail, the sliding groove of the sliding table 31 can not slide after contacting the rear bed leg 2, on the other hand, if the connection between the thigh plate 42 and the shank plate 43 is located on the sliding table 31, the shank plate 43 cannot be located in the vertical direction, which will affect the standing of the shank, and the knee of the elderly will bend somewhat, which will cause excessive stress and pain to the knee, therefore, a supporting surface 311 extending towards the bed tail is arranged at the top of the sliding table 31, the length of the supporting surface 311 is larger than the thickness of the back bed leg 2, the hinge point of the thigh plate 42 and the sliding table 31 is positioned on the supporting surface 311, the length from the sliding table 31 is larger than the thickness of the back bed leg 2, when the sliding table 31 is abutted against the back bed leg 2, the position of the hinge point is located outside the rear bed leg 2, and the lower leg plate 43 can be completely vertically downward under the action of gravity, so that the lower leg can completely step on the floor.

It should be noted that when the first push rod 5 pushes the sliding table 31 to slide towards the bed tail, the sliding table 31 drives the bed plate 4 hinged on the sliding table 31 through the thigh plate 42 to slide to the bed tail together, since the rear portion of the thigh plate 42 is hinged on the supporting surface 311 extended from the rear portion of the slide table 31, the shank plate 43 can be supported only on the frame 3, it can be seen that if the thickness of the thigh plate 42 is the same as that of the shank plate 43, the thigh plate 42 is inclined downward to the frame 3 for support when the thigh plate 42 is in a horizontal position, so that the knees of the elderly are bent at rest, and stress is applied for a long time, and for this reason, the thickness of the shank plate 43 is set to the sum of the thickness of the shank plate 42 and the thickness of the top of the slide table 31 so that the shank plate 43 is supported on the frame 3 in a horizontal state, the front end of the lower leg plate 43 needs to be provided with a relief portion of the support surface 311 of the slide table 31 so that the support surface 311 has sufficient strength to support the inversion of the upper body plate 41 and the lower leg plate 42. In order to move the bed plate 4 outward and prevent the height of the rear bed leg 2 from exceeding the height of the sliding table 31 from the ground, in the embodiment, the height of the rear bed leg 2 is flush with the height of the bed frame 3, so that the calf plate 43 of the bed plate 4 can move outward without any obstacle, when the first push rod 5 pushes the sliding table 31 to slide toward the tailstock, the calf plate 43 extends out of the bed frame 3 and the rear bed leg 2 and inclines downward under the action of gravity, and after the calf plate 43 completely extends out of the rear bed leg 2, the calf plate is in a vertical state under the action of gravity, so as to buffer the falling of the calf plate 43 and reduce the pain caused by the bending of the old people to the maximum extent, an arc-shaped chamfer is arranged on the outer side of the rear bed leg 2, the knee can be moved downward around the axis, so that the calf on the calf plate is gradually bent, thereby achieving the purpose of. Preferably, the lower leg plate 43 can be divided into an upper lower leg plate 431 and a lower leg plate 432, which are connected by a hinge, so that the cushioning can be performed in a segmented manner, which is more beneficial to reducing more pressure borne by the knee in bending. Of course, the lower leg plate 43 can be divided into more small plates hinged together.

In this embodiment, in order to reduce the friction force of the first push rod 5 pushing the slide table 31, a slide wheel may be provided in the slide table 31, the slide wheel may be in contact with the frame 3, the slide table 31 may be supported by the slide wheel to reciprocate on the frame 3, and the slide wheel may rotate when the slide table 31 is pushed, thereby reducing the pushing force pushing the slide table 31.

In this embodiment, the pneumatic spring 6 supports the upper body panel 41 by its own property, and does not serve as an electrically controlled power source to completely support the upper body panel 41 by pushing force, and only depends on the magnitude relation between the user's own weight and the working force of the pneumatic spring 6 to assist the second push rod 7 to lift and lower the upper body panel 41. Because the damper is arranged in the pneumatic spring 6, the resistance of the damper changes along with the running speed, the damper can obviously play a role in buffering the speed of a connected mechanism, and the requirement that the old people need to get up slowly is met. Therefore, the phenomenon that the pneumatic spring 6 is interfered and clamped is prevented, so that normal rotation is influenced, the preset position cannot be reached, and materials with high precision and good sealing performance need to be selected.

In the embodiment, the first push rod 5 and the second push rod 7 are electric push rods with self-locking devices, and the static stability of the upper body plate 41, the thigh plate 42 and the lower leg plate 43 is kept when the push rods do not work through self-locking, so that the use safety is improved. It should be noted that, the first push rod 5 and the second push rod 7 are electrically connected to a control system, and the control system controls the first push rod 5 and the second push rod 7 to extend and retract to achieve auxiliary getting on and off of the bed at the end of the bed, and how to connect and control the two push rods is a conventional means, and will not be described herein again.

In this embodiment, the rotation shaft provided on the thigh plate 42 may be provided integrally with the thigh plate 42, the rotation shaft may be fixed to the slide table 31 by a fixing member 9, and a bearing for engaging with the rotation shaft may be provided in the fixing member 9, so that the rotation shaft may be rotated with the axis of the rotation shaft as the rotation shaft when the second push rod 7 applies a pushing force to turn the thigh plate 42. In another embodiment, the rotation shaft provided on the thigh plate 42 may transversely penetrate the thigh plate 42, and has a gap with a through hole for penetrating the thigh plate 42, the rotation shaft is fixed on the sliding table 31 through the fixing member 9, when the second push rod 7 applies a pushing force to turn over the thigh plate 42, the thigh plate 42 will turn over around the axis of the rotation shaft, and the rotation shaft is fixed and will not turn over together with the thigh plate 42.
