Description

Technical Field

[0001] The utility model relates to the technical field of beds, in particular to an electric bed. Background Art

[0002] Electric beds are of course well-known and are ubiquitous in hospitals and have been used for a long time to provide more comfort for bedridden users. However, in addition to hospital use, electric beds are becoming increasingly common and popular in residences and apartments. In particular, people are using such beds to further enjoy their in-bed experiences (such as sleeping, reading, watching TV, etc.). Specifically, the back and headrest parts of the bed can usually be raised to different heights, so that when lying or sitting on the bed, a specific height can be selected during experiences such as sleeping, reading, or watching TV activities to improve the user's comfort. However, such a traditional bed has a problem: although the leg mechanism of the bed can be raised to a certain extent to keep the user's legs elevated for medical reasons (such as alleviating or preventing swelling of the user's legs or ankles), the leg mechanism of the bed cannot be lowered and cannot contact the floor (that is, when the user is lying flat, the legs cannot be bent naturally). The user does not always lie flat on the bed, and the user's legs are always placed horizontally, resulting in poor comfort. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: to solve the technical problem that the leg mechanism of the existing electric bed cannot be lowered and cannot contact the floor, which affects the comfort of the user. The utility model provides an electric bed. By improving the structure of the electric bed, the leg mechanism of the electric bed can be lowered to contact the floor to improve the comfort of the user's legs.

[0004] The technical solution adopted by the utility model to solve its technical problem is: an electric bed, comprising: a back plate, a thigh plate, a calf plate, a thigh frame, a calf frame, and a pivot pin mechanism. The thigh frame is connected to the thigh plate, the calf frame is connected to the calf plate. The pivot pin mechanism includes: a pivot pin and a locking pin. The thigh frame is connected to the calf frame through the pivot pin, and the thigh frame is connected to the calf frame through the locking pin. Wherein: when the locking pin is inserted into the thigh frame and the calf frame, the thigh plate and the calf plate are arranged in the same plane, the calf frame cannot rotate relative to the thigh frame, and the calf frame does not contact the floor; when the locking pin is removed from the thigh frame and the calf frame, the calf frame can rotate relative to the thigh frame, and the calf frame contacts the floor.

[0005] Thus, through the mutual cooperation of the pivot pin and the lock pin, the state of the calf plate relative to the thigh plate is adjusted, so that the calf plate can be switched back and forth between the horizontal state and the state of obliquely contacting the floor, and further, the placement state of the user's leg can be changed with the change of the state of the calf plate, which can improve the comfort of the user's leg.

[0006] Further, it further includes: a driving member, which is connected to the calf plate and is used to drive the calf plate to move up and down.

[0007] Further, it further includes: a head plate.

[0008] Further, it further includes: a backrest frame, the back plate is connected to the backrest frame, and the head plate is connected to the backrest frame.

[0009] Further, it further includes: a lumbar plate, which is located between the back plate and the thigh plate, and the lumbar plate is connected to the backrest frame.

[0010] Compared with the prior art, the beneficial effects of the present utility model are:

[0011] Through the mutual cooperation of the pivot pin and the lock pin, the state of the calf plate relative to the thigh plate is adjusted, so that the calf plate can be switched back and forth between the horizontal state and the state of obliquely contacting the floor, and further, the placement state of the user's leg can be changed with the change of the state of the calf plate, which can improve the comfort of the user's leg.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] Such as Figures 1 to 5As shown, this is the optimal embodiment of the present utility model. The electric bed 100 of this embodiment includes: a backrest plate 104, a thigh plate 112, a calf plate 114, a thigh frame 118, a calf frame 120, and a pivot pin mechanism. The thigh frame 118 is connected to the thigh plate 112, and the calf frame 120 is connected to the calf plate 114. The pivot pin mechanism includes: a pivot pin 140 and a locking pin 142. The thigh frame 118 is connected to the calf frame 120 through the pivot pin 140, and the thigh frame 118 is connected to the calf frame 120 through the locking pin 142. Wherein: when the locking pin 142 is inserted into the thigh frame 118 and the calf frame 120, the thigh plate 112 and the calf plate 114 are arranged in the same plane, the calf frame 120 cannot rotate relative to the thigh frame 118, and the calf frame 120 does not contact the floor; when the locking pin 142 is removed from the thigh frame 118 and the calf frame 120, the calf frame 120 can rotate relative to the thigh frame 118, and the calf frame 120 contacts the floor. Thus, through the mutual cooperation of the pivot pin 140 and the locking pin 142, the state of the calf plate 114 relative to the thigh plate 112 is adjusted, so that the calf plate 114 is in a horizontal state (i.e., the first state as shown in Figure 2 ), and the state of tilting and contacting the floor (i.e., the second state as shown in Figure 4 ) are switched back and forth, thereby enabling the placement state of the user's leg to change with the change of the state of the calf plate 114, and improving the comfort of the user's leg.

[0023] Specifically, the pivot pin 140 mechanism further includes: a first connecting plate 132 and a second connecting plate 134. The first connecting plate 132 is installed on the thigh frame 118, and the second connecting plate 134 is installed on the calf frame 120. First through holes 136 and second through holes 138 are formed on both the first connecting plate 132 and the second connecting plate 134. The first through hole 136 is used to install the pivot pin 140, and the second through hole 138 is used to install the locking pin 142. When the pivot pin 140 is installed in the first through hole 136 and the locking pin 142 is installed in the second through hole 138, the calf frame 120 cannot rotate relative to the thigh frame 118, and the calf plate 114 is always arranged in the same plane as the thigh plate 112. When the pivot pin 140 is installed in the first through hole 136 and the locking pin 142 is not installed in the second through hole 138, the calf frame 120 can rotate relative to the thigh frame 118 (i.e., the calf frame 120 rotates relative to the pivot pin 140), and the calf frame 120 contacts the floor.

[0024] Specifically, the first state refers to the state where the thigh plate 112 and the calf plate 114 are in the same plane; the second state refers to the state where the calf plate 114 is inclined relative to the thigh plate 112.

[0025] In this embodiment, it further includes: a driving member 150, which is connected to the calf plate 114 and is used to drive the calf plate 114 to move up and down. Specifically, the driving member 150 is rotatably connected to the thigh plate 112, and the driving end of the driving member 150 is rotatably connected to the calf plate 114. Thus, when the locking pin 142 is not installed in the second through hole 138 (that is, when the locking pin 142 cannot restrict the thigh frame 118 and the calf frame 120), the driving member 150 is activated, and the driving member 150 can control the lifting of the calf plate 114.

[0026] It should be noted that: the driving member 150 can control the inclination degree of the calf plate 114 relative to the thigh plate 112, that is, by controlling the telescopic degree of the driving member 150, the calf plate 114 can be controlled to stay in any state between the first state and the second state.

[0027] Specifically, a second support leg 128 is installed on the thigh frame 118.

[0028] For example, the driving member 150 is a push rod motor.

[0029] In this embodiment, it further includes: a head plate 102, a waist plate 106, and a backrest frame 116. The back plate 104 is connected to the backrest frame 116, the head plate 102 is connected to the backrest frame 116, the waist plate 106 is located between the back plate 104 and the thigh plate 112, and the waist plate 106 is connected to the backrest frame 116. Specifically, it further includes: a first seat plate 108 and a second seat plate 110. The first seat plate 108 is connected to the backrest frame 116, and the first seat plate 108 is located on the side of the waist plate 106 close to the second seat plate 110. The second seat plate 110 is connected to the thigh frame 118, and the second seat plate 110 is located on the side of the thigh plate 112 close to the waist plate 106.

[0030] Specifically, a first support leg 126 is installed on the backrest frame 116.

[0031] The rotation process of the calf plate 114 of the present utility model is as follows: 1. When the pivot pin 140 is installed in the first through hole 136 and the locking pin 142 is installed in the second through hole 138, the calf frame 120 cannot rotate relative to the thigh frame 118, and the calf plate 114 is always coplanar with the thigh plate 112;

[0032] 2. When the pivot pin 140 is installed in the first through hole 136 and the locking pin 142 is not installed in the second through hole 138, at this time, the driving member 150 is activated, and the driving member 150 is controlled to contract. Under the action of gravity, the calf frame 120 will rotate relative to the pivot pin 140 and rotate towards the side close to the floor, and finally contact the floor.

[0033] In summary, through the mutual cooperation of the pivot pin 140 and the locking pin 142, the present utility model adjusts the state of the lower leg plate 114 relative to the upper leg plate 112, enabling the lower leg plate 114 to switch back and forth between a horizontal state and a state of being inclined to contact the floor. Furthermore, the placement state of the user's leg can change with the change of the state of the lower leg plate 114, thereby improving the comfort of the user's leg.

[0034] The above is based on the ideal embodiments of the present utility model as inspiration. Through the above description, relevant staff can, without departing from the technical idea of this utility model, make various changes and modifications. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
