Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Embodiment 1
[0028] Reference Figure 1-4 As shown, a rollover-proof bed of the utility model comprises a main bed frame 1, on which a pad group 2 is installed, and also comprises a lifting mechanism 3, wherein the lifting mechanism 3 comprises a driving assembly hingedly installed below the main bed frame 1, a push rod of the driving assembly hingedly connected to a swing arm 31, and the swing arm 31 is also hingedly connected to the main bed frame 1 and a first fence rod 33, the first fence rod 33 is hingedly connected to a connecting rod 34, the connecting rod 34 is hingedly connected to a second fence rod 36, the second fence rod 36 is hingedly connected to a rotating arm 35, the rotating arm 35 is hinged to the main bed frame 1, and both ends of the connecting rod 34 are also hingedly connected to the main bed frame 1, so that the rotational movement of the swing arm 31 can be transmitted to the second fence rod 36 and the rotating arm 35 through the first fence rod 33 and the connecting rod 34, the first fence rod 33 and the second fence rod 36 are respectively arranged on both sides of the main bed frame 1, and an elastic belt 32 is also sleeved therebetween, and the elastic belt 32 is a cloth belt with good telescopic performance.
[0029] The main bed frame 1 can be used alone as an outdoor bed or stretcher. The two fence rods of the lifting mechanism 3 are synchronously lowered or raised under the push of the driving assembly, and the elastic belt 32 is assisted by the flattening or upward lifting, which can facilitate the patient to be lifted onto the main bed frame 1 or elastically restrain the patient's body to prevent the patient from tipping over and falling. In addition, the main bed frame 1 can also be used as a movable bed in combination with the bottom support structure. Casters and brake components are set at the bottom of the support structure to assist in movement or brake stopping. A height adjustment mechanism can also be set on the support structure to adjust the overall height of the main bed frame 1, so that the bed can be used in various occasions.
[0030] Embodiment 2
[0031] Reference Figure 1-4 As shown, based on the technical solution of the first embodiment, a rollover-proof bed, for the structural design of the power transmission component of the lifting mechanism 3, four extension plates are fixed below the main bed frame 1, and one end of the swing arm 31 and the rotating arm 35 and the two ends of the connecting rod 34 are respectively hinged to a single extension plate. The four extension plates have the same structure and are symmetrically arranged on the main bed frame 1. Specifically, the two extension plates on one side of the main bed frame 1 are symmetrically positioned, and the extension plates on both sides of the main bed frame 1 are also symmetrically arranged. The extension plate is a right-angle plate, that is, formed by a piece of cardboard through a 90-degree bend, and one bent surface of the extension plate is welded to the bottom of the main bed frame 1, and a through hole is processed on the other bent surface of the extension plate and connected to one end of the swing arm 31 or the rotating arm 35 or the two ends of the connecting rod 34 through a bare rod bolt.
[0032] Furthermore, both ends of the first fence rod 33 are at the same height as the hinges of the swing arm 31 and one end of the connecting rod 34, and both ends of the second fence rod 36 are at the same height as the hinges of the rotating arm 35 and the other end of the connecting rod 34. In addition, the first fence rod 33 and the second fence rod 36 are symmetrically arranged.
[0033] The first fence rod 33, the two extension plates on one side of the main bed frame 1, one end of the connecting rod 34 and the swing arm 31 form a parallelogram structure, wherein the four hinged parts of the above components are the four connection points of the parallelogram. In this way, the swing arm 31 rotates to drive the lifting movement of the first fence rod 33, and the swing arm 31 is just hinged with a push rod, which pushes outward or retracts inward through a driving component hinged under the main bed frame 1. In addition, the two ends of the connecting rod 34 are respectively hinged to the two extension plates on the main bed frame 1 and the two fence plates. When the first fence rod 33 is lifted or lowered, the second fence plate can be lifted and lowered synchronously. Combined with the two ends of the rotating arm 35, which are respectively hinged to the extension plate and the second fence rod 36 on the main bed frame 1, the connecting parts of the second fence rod 36 can also form a parallelogram structure. The specific analysis is the same as above and will not be repeated here. When the push rod extends outward, it drives the swing arm 31 to rotate around the hinge of the extension plate, causing the first fence rod 33 to descend, and drives the connecting rod 34 to rotate synchronously with the hinge of the extension plate, causing the second fence rod 36 to descend synchronously, and at the same time, the elastic belt 32 descends to flatten the patient so that the patient can move parallel to the bed; when the push rod retracts inward, it drives the swing arm 31 to rotate around the hinge of the extension plate, driving the first fence rod 33 to rise, and drives the connecting rod 34 to rotate synchronously with the hinge of the extension plate, causing the second fence rod 36 to rise synchronously, and at the same time, the elastic belt 32 rises to protect the patient from sliding when he rolls over on the bed.

Specifically, the swing arm 31 is equivalent to being a lever, and the hinged part of the swing arm 31 and the extension plate on the main bed frame 1 is used as the fulcrum of the lever. The push rod is located at one end of the lever to apply a force, driving the first fence rod 33 located at the other end of the lever to change its height accordingly. In order to ensure the stroke size and smooth operation, both ends of the lever are connected by a hinged connection.
[0036] As for the specific structural design of the connecting rod 34 of the lifting mechanism 3, the connecting rod 34 includes a crossbar and two vertical plates, the vertical plates are symmetrically fixed at the two ends of the crossbar, the two ends of one vertical plate are respectively hinged to the main bed frame 1 and the first fence rod 33, and the two ends of the other vertical plate are respectively hinged to the main bed frame 1 and the second fence rod 36. Generally, a vertical plate is welded to each end of the crossbar, and the vertical plates are convenient for processing through holes and installing rotating shafts. The two ends of one vertical plate are rotatably connected to the extension plate on the main bed frame 1 and the first fence rod 33 through the rotating shaft, and the two ends of the other vertical plate are rotatably connected to the extension plate on the main bed frame 1 and the second fence rod 36 through the rotating shaft.
[0037] Furthermore, the driving assembly further comprises a lifting motor 37, the end of which is hingedly mounted on the fixed plate 11 below the main bed frame 1, and the end of the push rod is hingedly connected to the swing arm 31. The lifting motor 37 and the internal screw mechanism are used to drive the push rod to move linearly, and the two ends of the driving assembly are respectively hingedly connected to other components, so that the push rod can change the angle to push outward or retract inward, and the overall power transmission is balanced and stable.
[0038] Furthermore, the main bed frame 1 comprises a first bed frame 12 which is fixedly installed, and the second bed frame 13 and the third bed frame 14 are respectively hinged on both sides of the first bed frame 12, and the third bed frame 14 is hinged on the fourth bed frame 15. The first bed frame 12, the second bed frame 13, the third bed frame 14 and the fourth bed frame 15 are respectively covered with pads of the pad group 2. When the main bed frame 1 is installed together with the supporting structure at the bottom, other lifting components can be arranged under the main bed frame 1 to realize the lifting and lowering of each bed frame, such as lifting or lowering the position of the bed frame where the patient's backrest or thighs and calves are located, which will not be described in detail here.
[0039] The drive assembly uses an electric push rod, also known as a linear drive, which is a new type of linear actuator mainly composed of a motor, a push rod, a control device, etc. The electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. After the motor is reduced by gears or worm gears, it drives a pair of screw nuts to work, thereby converting the rotational motion of the motor into linear motion, and the push rod action is completed by the forward and reverse rotation of the motor.
[0040] The standard parts used in the device of the utility model can all be purchased from the market. The assembly and matching relationship of the various components involved, the lifting motor 37, the electric push rod and its supporting control software are existing technologies or materials. The relevant technical personnel can directly purchase or customize them from the market according to the required product models and specifications.
[0041] The electrical components mentioned in the text are all connected to an external main controller and 220V mains or industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.
[0042] The above is only a preferred specific embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned embodiment, and the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive.
