[0002] As one of the essential tools in people's daily life, folding beds can reduce the labor intensity during handling and can be folded and stored to save space. Therefore, folding beds are currently widely used in daily homes, hospital care, hotels, and other places where lying is required. However, manual folding beds are rather troublesome and time-consuming and laborious.

[0003] Based on this, electric folding beds have emerged on the market to solve the problems of manual folding beds being troublesome and time-consuming and laborious. However, in existing electric folding beds, the middle push rod motor is used for lifting, and when one side of the folding bed is subjected to unilateral force, situations such as swinging and abnormal noises are likely to occur.

[0004] Based on this, the inventor proposes a one-key electric folding bed to solve the above technical problems. Summary of the Invention

[0009] The technical effect after adopting this technical solution is that the first mattress is relatively rotatably connected to the first bed body, and the second mattress is relatively rotatably connected to the second bed body, ensuring that when the folding bed is folded, it can be stored to reduce the occupied space. The first mattress and the second mattress are relatively soft, and it is more comfortable for users to lie on them.

[0010] In this embodiment, the folding bed further includes: a fixed seat, a first rotating shaft is installed on the fixed seat; a first hinged rod, one end of the first hinged rod is rotatably connected to the fixed seat; the other end of the first hinged rod is hinged to a third fixing rod, and the third fixing rod is fixedly connected to the first mattress; a second hinged rod, the first hinged rod and the second hinged rod are arranged in a cross shape, one end of the second hinged rod is rotatably connected to the fixed seat; the other end of the second hinged rod is hinged to a fourth fixing rod, and the fourth fixing rod is fixedly connected to the second mattress.

[0012] In this embodiment, limiting stop rods for limiting the first mattress and the second mattress are provided on both the first bed body and the second bed body.

[0013] The technical effect after adopting this technical solution is that when the first bed body and the second bed body are unfolded, limiting stop rods are provided on one side of the first bed body and the second bed body, so that the first mattress and the second mattress do not slide under the action of the limiting stop rods.

[0014] In this embodiment, the first bed body includes a first bed body main body arranged in a net shape and a first main frame body, and the first bed body main body and the first main frame body are fixedly connected by fasteners; the second bed body includes a second bed body main body arranged in a net shape and a second main frame body, and the second bed body main body and the second main frame body are fixedly connected by fasteners.

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is given.

[0033]

First Embodiment

[0034] In this embodiment, the first linear actuator 3 is a stepping motor, the output shaft of the first linear actuator 3 is pivotally connected to a first connecting member 5, one end of the first connecting member 5 is rotatably connected to a first main shaft 6, and the rotation of the first linear actuator 3 drives the first main shaft 6 to rotate, so that the rotation of the first rotating shaft 14 drives the first bed body 1 to rotate along the first rotating shaft 14. In addition, the first flipping mechanism includes the first main shaft 6, a push rod 31 is fixedly connected to the side wall of the first main shaft 6, a roller 32 is provided at the end of the push rod 31 away from the first main shaft 6, and the surface of the roller 32 abuts against one side of the first bed body 1, so that a thrust is applied to the first bed body 1 while the first main shaft 6 rotates, ensuring the stability of the rotation of the first bed body 1 during folding.

[0035] Similarly, the output shaft of the second linear actuator 4 is pivotally connected to a second connecting member 7, one end of the second connecting member 7 is rotatably connected to a second main shaft 8, and the rotation of the second linear actuator 4 drives the second main shaft 8 to rotate, so that the rotation of the second main shaft 8 drives the first bed body 1 to rotate along the first rotating shaft 14. In addition, the second flipping mechanism includes the second main shaft 8, a push rod 31 is fixedly connected to the side wall of the second main shaft 8, a roller 32 is provided at the end of the push rod 31 away from the second main shaft 8, and the surface of the roller 32 abuts against one side of the first bed body 2, so that a thrust is applied to the first bed body 2 while the second main shaft 8 rotates, ensuring the stability of the rotation of the second bed body 2 during folding.

[0036] When the folding bed needs to be folded, the first bed body 1 and the second bed body 2 move closer to each other.

[0037] The first bed body 1 and the second bed body 2 can be wire beds, wooden beds, etc. The first bed body 1 and the second bed body 2 are specifically connected by a pivotal connection method, so that the rotation directions of the first bed body 1 and the second bed body 2 are opposite.

[0038] The button can be installed at any position on the folding bed, mainly controlling the opening and closing of the first linear actuator 3 and the second linear actuator 4. The first linear actuator 3 and the second linear actuator 4 can use stepping motors of the same specification. Since the installation directions of the first linear actuator 3 and the second linear actuator 4 are opposite, when the button is activated to start the first linear actuator 3 and the second linear actuator 4, the first linear actuator 3 drives the first bed body 1 to rotate clockwise, while the second linear actuator 4 drives the second bed body 2 to rotate counterclockwise, so as to achieve the purpose that the first bed body 1 and the second bed body 2 move closer to each other and fold together.

[0039] The button can be set as a contact button and is connected to a controller (not shown in the figure).
