[0026] The specific settings and functions of this embodiment are described in detail below. When the bed 1 is in use, its top is matched with an airbag mattress, and the patient lies on the top of the bed 1. When the patient is heavy, it is very difficult for the medical staff to push the bed 1. By setting a motor 310, a gear 2 36, a gear 1 35 and a connecting rod 34, the motor 310 is started to drive the gear 2 36 and the gear 1 35 to rotate, and then the gear 1 35 drives the connecting rod 34 and the two sets of wheels 1 33 to rotate. The wheel 1 33 is located on the patient's foot side of the bed 1.

By setting the threaded rod 37, the hand turntable 38 and the support seat 39, when the bed body 1 is pushed, the support seat 39 is adjusted to move up, so that the bed body 1 can be driven to move when the wheel 33 rotates. When the bed body 1 stops at a certain position, the support seat 39 is adjusted to move down so that the bottom of the support seat 39 contacts the ground. Due to the large friction between the bottom of the support seat 39 and the ground, the bed body 1 and the fixed frame 2 are kept in this position.
[0027] Embodiment 2
[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the front wheel drive 4 includes a second fixing seat 41 and a second wheel 45. The top of the second fixing seat 41 is fixedly connected to the bottom of the fixing frame 2. The bottom of the second fixing seat 41 is rotatably connected with two groups of connecting plates 42. One side of the connecting plate 42 is rotatably connected with a mounting plate 43. A second connecting shell 44 is rotatably connected between the two groups of mounting plates 43. Both sides of the second wheel 45 are rotatably connected to the inner wall of the second connecting shell 44. A damper 46 is fixedly installed on the top of the second connecting shell 44. One end of the damper 46 is fixedly connected to the bottom of the second fixing seat 41.
[0029] The effect achieved by the entire embodiment is that during the movement of the bed 1, when the bottom of the second wheel 45 rolls over some unstable impurities, the impurities push the second wheel 45 and the second connecting shell 44 upward, and the connecting piece 42 and the mounting piece 43 cooperate with the movement of the second connecting shell 44 to deflect. By setting the second connecting shell 44 and the damper 46, the damper 46 absorbs the energy of the second connecting shell 44 and the second wheel 45 moving upward, absorbs and reduces the impact and vibration of the bed 1 during the movement, increases the stability of the bed 1 during the movement, and helps the patient's comfort and safety on the bed 1.
[0030] The use method and working principle of this device: when the bed 1 is in use, its top is matched with an airbag mattress, and the patient lies on the top of the bed 1. When the patient is heavy, it is very difficult for the medical staff to push the bed 1. The motor 310 is started to drive the gear 2 36 and the gear 1 35 to rotate, and then the gear 1 35 drives the connecting rod 34 and the two sets of wheels 1 33 to rotate. The wheel 1 33 is located on the patient's foot side of the bed 1. Through the operation of the motor 310, the medical staff is helped to push the bed 1. The setting of the connecting rod 34 makes the rotation and deflection direction of the wheel 1 33 synchronized. The connecting shell 1 32 and the wheel 1 33 deflect at the bottom of the fixed seat 1 31, so as to realize the silky rotation and movement of the wheel 1 33 in all directions, and the rotation of the wheel 1 33 is more synchronized, and the hand turntable is rotated. 38, drives the threaded rod 37 to rotate inside the connecting shell 32, and the threaded rod 37 will drive the support seat 39 to move up and down when rotating. When the bed body 1 is pushed, the support seat 39 is adjusted to move up, so that the wheel 33 can drive the bed body 1 to move when rotating. When the bed body 1 stops at a certain position, the support seat 39 is adjusted to move down so that the bottom of the support seat 39 contacts the ground. During the movement of the bed body 1, when the bottom of the wheel 2 45 rolls over some unstable impurities, the impurities push the wheel 2 45 and the connecting shell 2 44 upward, and the connecting plate 42 and the mounting plate 43 cooperate with the movement of the connecting shell 2 44 to deflect, and the damper 46 absorbs the energy of the connecting shell 2 44 and the wheel 2 45 moving upward, so as to absorb and reduce the impact and vibration of the bed body 1 during the movement.
