Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1 to 5 The utility model provides a kind of auxiliary standing device, including rack 1, seat pad 2, back pad 3, handrail 4, connecting rod 5 and first driving member 6, one side of the seat pad 2 is hinged with the rack 1 by first hinged point 11, other side is hinged with the back pad 3 by second hinged point 12, the seat pad 2 is used to support the hip and thigh of human body, the back pad 3 is used to support the back of human body, one end of the first driving member 6 is hinged with the rack 1, other end is hinged with the seat pad 2 by third hinged point 13, the third hinged point 13 is located between the first hinged point 11 and the second hinged point 12, the end of the connecting rod 5 is slidably connected with the rack 1, the rod body of the connecting rod 5 is arranged in the back pad 3 and is slidably connected with the back pad 3, the back pad 3 is fixedly connected with the handrail 4, the handrail 4 is used to support the hand of human body, the first driving member 6 is used to drive the seat pad 2 to overturn, so that the end of the connecting rod 5 is slid along horizontal direction on the rack 1 to be close to the first hinged point 11, while making the back pad 3 slide along vertical direction on the rod body of the connecting rod 5 and slide upwards.

[0022] The rack 1, seat pad 2, back pad 3, handrail 4 and connecting rod 5 in the application are made of firm aviation grade 6061-T6 aluminum alloy metal material. This material is known for its excellent strength-to-weight ratio, suitable for high-performance, lightweight design requirements. The first driving member 6 can adopt electric cylinder or air cylinder. When air cylinder is used, air cylinder takes compressed air as power source, and converts the energy of compressed air into linear reciprocating motion. When compressed air is supplied, the piston of air cylinder is subjected to gas pressure, slides along the cylinder to push the piston rod, realizes the piston rod extension or retraction action, and further drives the seat pad 2 to overturn. When electric cylinder is used, the piston rod of electric cylinder is directly hinged with the seat pad 2, and the seat pad 2 is driven to overturn by the piston rod extension or retraction action. The first driving member 6 is driven by the user himself, which is a conventional technology in the art, and will not be described here.

[0023] When the first driving member 6 drives the seat cushion 2 to flip, the seat cushion 2 provides an upward supporting force for the buttocks of the human body. Since the seat cushion 2 is connected with the back cushion 3 through the second hinge point 12, the seat cushion 2 lifts the back cushion 3, so that the back cushion 3 slides upward along the vertical direction on the rod body of the connecting rod 5. Since the end of the connecting rod 5 is slidingly connected with the frame 1, the end of the connecting rod 5 slides along the horizontal direction on the frame 1 to approach the first hinge point 11. The above process makes the back cushion 3 support the human body to move forward in the horizontal direction during the flipping of the seat cushion 2. Since the armrest 4 is fixedly connected with the back cushion 3, the armrest 4 moves forward along with the back cushion 3 during the flipping of the seat cushion 2, so that the armrest 4 and the back cushion 3 always provide a supporting force for the hands during the conversion of the disabled person or the old person from the sitting position to the standing position. The seat cushion 2 of the present application can be adjusted, and can assist the user to stand, guide the user to stand and protect the user to smoothly complete the conversion from the sitting position to the standing position.

[0024] When it is needed to restore the seat cushion 2 to the original position, the first driving member 6 drives the seat cushion 2 to flip downward, and correspondingly, the back cushion 3 slides downward along the vertical direction on the rod body of the connecting rod 5. Since the end of the connecting rod 5 is slidingly connected with the frame 1, the end of the connecting rod 5 slides along the horizontal direction on the frame 1 to move away from the first hinge point 11.

[0025] In addition, since the present application drives the seat cushion 2 to flip through the first driving member 6, the present application can adjust the supporting angle according to the daily use and work requirements of the user, so that the user can maintain the required standing posture.

[0026] In an available embodiment, a foot pad 7 and a second driving member 8 are further included, one side of the foot pad 7 is hingedly connected with the frame 1, the foot pad 7 is used for supporting the lower leg of the human body, one end of the second driving member 8 is hingedly connected with the foot pad 7, and the other end is hingedly connected with the frame 1, and the second driving member 8 is used for driving the foot pad 7 to flip. In the embodiment, the second driving member 8 can adopt an electric cylinder or a pneumatic cylinder. When the lower leg of the user is placed on the foot pad 7, the second driving member 8 drives the foot pad 7 to flip, the foot pad 7 drives the lower leg to rotate, and thus the angle of the lower leg is changed. In addition, when the second driving member 8 flips the foot pad 7 to the vertical direction, the user can be protected during the conversion from the sitting position to the standing position. Specifically, when the foot pad 7 is placed in the vertical direction, the lower leg of the user can be prevented from stretching backward into the lower part of the seat cushion 2, and the situation of falling down due to incorrect standing position can be avoided.

[0027] In an embodiment, a support assembly 9 is further included, which is connected with the frame 1 and arranged in a vertical direction in front of the seat cushion 2 and can be held by hands of a human body. During the process of converting from a sitting position to a standing position, the human body may fall forward due to the center of gravity. In this embodiment, the support assembly 9 is arranged in front of the seat cushion 2, so that when the human body falls forward during the process of converting from a sitting position to a standing position, the hands of the user can be supported on the support assembly 9 to avoid falling.

[0028] In an embodiment, the support assembly 9 includes a third driving member 91 arranged in a vertical direction and a holding portion 92 arranged at a power output end of the third driving member 91, which can be held by hands of a human body, and the third driving member 91 is used to drive the holding portion 92 to move in a vertical direction to adjust the height of the holding portion 92. The holding portion 92 can be arranged as a handle or a knob to be more convenient for the user to hold. In this embodiment, the third driving member 91 is a pneumatic cylinder and an electric cylinder. The third driving member 91 drives the holding portion 92 to move in a vertical direction, which is adjusted according to the height and body shape of the old person, so that the user can hold the handle or the knob to obtain stable support and assistance for standing. Further, in order to improve the application range of the support assembly 9, the third driving member 91 can be a multi-stage telescopic cylinder. The multi-stage telescopic cylinder is composed of a plurality of sleeves with gradually decreasing sizes. These sleeves are sequentially stretched during the telescopic process, so as to realize a longer telescopic stroke. When pressure is applied, the largest tube or main cylinder is first stretched, and once it is fully stretched, the next tube starts to stretch, and this process continues until all the sleeves are stretched.

[0029] Further, the support assembly 9 further comprises a first baffle 93, a second baffle 94 and a third baffle 95. The first baffle 93 is fixedly connected with the third driving member 91. The first baffle 93 is provided with a first slot 931. The second baffle 94 is inserted into the first slot 931. The second baffle 94 is provided with a second slot 941. The third baffle 95 is inserted into the second slot 941. The third baffle 95 is fixedly connected with the holding portion 92 at a side extending out of the second slot 941. The third baffle 95 is provided with a hanging column 951 at a side extending into the second slot 941. The second baffle 94 is provided with a hanging groove 952 matched with the hanging column 951. The holding portion 92 is used to drive the third baffle 95 to move out of the second slot 941. The hanging column 951 is used to abut against the top of the hanging groove 952 to drive the second baffle 94 to move out of the first slot 931. The present embodiment is applicable to the case that the third driving member 91 is a multi-stage telescopic cylinder. Specifically, when the first baffle 93, the second baffle 94 and the third baffle 95 are inserted into each other, the first baffle 93 is accommodated in the second slot 941, and the second baffle 94 is accommodated in the first slot 931. When the holding portion 92 is driven by the third driving member 91 to move upward, the first baffle 93 is driven to move upward due to the fixed connection between the holding portion 92 and the first baffle 93. At the same time, the hanging column 951 moves upward in the hanging groove 952 until abutting against the top of the hanging groove 952. When the holding portion 92 continuously moves upward, the second baffle 94 is driven to move upward by the hanging column 951, and the second baffle 94 moves out of the first slot 931. When the first baffle 93, the second baffle 94 and the third baffle 95 are inserted into each other, the occupied space can be reduced. When the first baffle 93, the second baffle 94 and the third baffle 95 are unfolded, a baffle with a large area can be formed to provide effective protection for the user.

[0030] In a feasible embodiment, a fourth driving member 10 is further included. The support assembly 9 is slidingly connected with the frame 1. The fourth driving member 10 is used to drive the support assembly 9 to slide on the frame 1 along the horizontal direction. In the present embodiment, the fourth driving member 10 can be an electric cylinder or a pneumatic cylinder. In the present embodiment, the support assembly 9 slides on the frame 1 along the horizontal direction. When the user does not need the support assembly 9, in order to avoid the support assembly 9 occupying the space in front of the seat cushion 2, the fourth driving member 10 can be used to recover the support assembly 9 to the lower side of the seat cushion 2.

[0031] Specifically, the support assembly 9 includes a sliding seat 96, the bottom surface of which is provided with a limiting protrusion 961, and the frame 1 is provided with a limiting groove 962 that matches the limiting protrusion 961. The limiting protrusion 961 is inserted into the limiting groove 962 to define the sliding path of the sliding seat 96. The side of the sliding seat 96 is provided with a connecting column 963, which is connected to the power output end of the fourth drive member 10. The connecting column 963 is rotatably connected to a roller 964. The frame 1 is provided with a guide rail 965 that cooperates with the roller 964. The fourth drive member 10 is used to drive the connecting column 963 so that the roller 964 rolls on the guide rail 965. In this embodiment, the limiting protrusion 961 and the limiting groove 962 define the sliding path of the sliding seat 96, preventing deviation during the sliding process. At the same time, the arrangement of the roller 964 and the guide rail 965 can reduce the resistance of the fourth driving member 10 when pushing the sliding seat 96 to move.
