As shown in fig. 1 to 4, the present utility model provides a bed frame 100 including a base 5, a first frame 1, a second frame 2, a third frame 3, a fourth frame 4, and further including a first swing arm 6 and a second swing arm 7 which are selectively used.

The first frame 1 is used for supporting buttocks of a human body, the first frame 1 is connected with the base 5 and is positioned below the base 5, the second frame 2 is used for supporting the back of the human body, the second frame 2 is movably connected with the first end 101 of the first frame 1, the third frame 3 is used for supporting thighs of the human body, the third frame 3 is movably connected with the second end 102 of the first frame 1, the fourth frame 4 is used for supporting the thighs of the human body, one end of the fourth frame 4 is hinged with the third frame 3, and the other end of the fourth frame 4 is a suspension end 403.

The bed frame 100 has a first use state in which the first swing arm 6 is used and a second use state in which the second swing arm 7 is used.

In the first use state, as shown in fig. 1 and 2, the first rocker arm 6 is connected between the first frame 1 and the fourth frame 4, and two ends of the first rocker arm 6 are rotatably connected with the first frame 1 and the fourth frame 4 respectively. When the third frame 3 and the fourth frame 4 are deformed relative to the base 5 and the first frame 1, the first swing arm 6 swings with the change of the position of the fourth frame 4, thereby restricting the change of the angle of the fourth frame 4 and playing a certain supporting role.

In the second use state, as shown in fig. 3 and 4, the base 5 of the bed frame 100 is fixedly connected to the base 200, the second swing arm 7 is connected between the base 200 and the fourth frame 4, and two ends of the second swing arm 7 are rotatably connected with the base 200 and the fourth frame 4, respectively. Similarly, when the third frame 3 and the fourth frame 4 are deformed relative to the base 5 and the first frame 1, the second swing arm 7 swings with the change of the position of the fourth frame 4, thereby restricting the change of the angle of the fourth frame 4 and playing a certain supporting role. It will be appreciated that by designing the parameters such as the position, length, etc. of the first rocker arm 6 and the second rocker arm 7, the deformation of the fourth frame 4 in the two states can be the same or nearly the same, alternatively, when the inclination angle of the third frame 3 is the same, the difference of the inclination angles of the fourth frame 4 in the two using states is not more than 5 °, and the height difference of the suspending end 403 is not more than 30mm, so that the bed frame has almost uniform using experience when used in different using states.

The frame 100 includes a first swing arm 6 and a second swing arm 7 that are selectively used, and has a first use state in which the first swing arm 6 is used and a second use state in which the second swing arm 7 is used, it being understood that the second swing arm 7 may not be installed when the first swing arm 6 is used, and the first swing arm 6 may not be installed when the second swing arm 7 is used. When the bed frame 100 is in the first use state, the base 5 can be fixed or placed on a horizontal bed board, and the fourth frame 4 can be lifted to a limited extent, so that daily use can be satisfied. Since the second swing arm 7 is supported between the base 200 and the fourth frame 4 when the frame 100 is in the second use state, the supporting effect of the fourth frame 4 can be improved, so that the frame 100 can be reliably used on the base 200 having a smaller floor space, and generally, the length of the base 200 is smaller than that of the frame 100. By selectively using the first rocker arm 6 and the second rocker arm 7, the bed frame 100 can be used on the bed board or the base 200 as required, and the application range is wider.

As shown in fig. 1 to 4, the fourth frame 4 includes a first connection portion 401 for connecting the first swing arm 6 and a second connection portion 402 for connecting the second swing arm 7, wherein the first connection portion 401 is closer to the third frame 3 than the second connection portion 402, and the second connection portion 402 is closer to a suspension end 403 of the fourth frame 4, and it can be understood that the suspension end 403 is located at the tail of the bedframe 100. Since the second connection part 402 is closer to the suspended end of the fourth frame 4 than the first connection part 402, the second swing arm 7 has a better supporting effect on the fourth frame 4, and can have a good supporting effect when the frame 100 is mounted on the base 200, and does not cause damage to the frame 100 even if sitting on the fourth frame 4.

The first frame 1 comprises a third connection 501 for connection to the first swing arm 6, the third connection 501 extending towards the side of the base 5 (i.e. below), preferably below the third frame 3, such that the first swing arm 6 is located below the third frame 3. The base 200 includes a fourth connection portion 2003 for connection with the second swing arm 7, the fourth connection portion 2003 being located directly under the fourth frame 4 to further enhance the supporting strength of the second swing arm 7 to the fourth frame 4. Along the length direction of the frame 100, the first connection part 401 is located between the third connection part 501 and the fourth connection part 2003.

Optionally, as shown in fig. 3 and 4, the bed frame 100 further includes a transition plate 8 detachably connected to the third connecting portion 501, and the second swing arm 7 is selectively connected to the transition plate 8, or the transition plate 8 is detached to be connected to the third connecting portion 501, so as to adjust the position change of the fourth frame 4 when the bed frame 100 is deformed.

As shown in fig. 2, the bed frame further includes a rotation shaft assembly 9, and the first swing arm 6 is connected to the first connecting portion 401 and the third connecting portion 501, and the second swing arm 7 is connected to the second connecting portion 402 and the fourth connecting portion 801 through the rotation shaft assembly 9, so that two ends of the first swing arm 6 and the second swing arm 7 form a revolute pair through the rotation shaft assembly 9, and can swing along with the position change of the fourth frame 4 when the bed frame 100 is deformed.

Taking the example of connecting the first connecting portion 401 and the first rocker arm 6 by using the rotating shaft assembly 9 as an example, in some embodiments, as shown in fig. 5 and 6, the rotating shaft assembly 9 includes a rotating shaft 901 penetrating between the first rocker arm 6 and the first connecting portion 401 and a fixing member 902 detachably connected to the rotating shaft 901, and the rotating shaft 901 enables relatively smooth rotation between the first rocker arm 6 and the first connecting portion 401. The rotating shaft 901 is provided with a first limiting boss 903, and the fixing member 902 and the first limiting boss 903 are respectively located at both sides of the first rocker arm 6 and the first connecting portion 401, so that the rotating shaft 901 can be reliably held in the first limiting boss 903 and the first rocker arm 6. In the embodiment shown in fig. 5 to 7, the rotating shaft 901 is provided with a threaded hole 905, the fixing piece 902 is connected with the threaded hole 905, the fixing piece 902 is provided with a second limiting boss 904 located outside the threaded hole 905, and the first limiting boss 903 and the second limiting boss 904 are located on two sides of the first rocker arm 6 and the first connecting portion 401, respectively. In other embodiments, as shown in fig. 8, the rotating shaft 901 may be provided with external threads, and the fixing member 902 may be, for example, a nut, which is screwed to the outside of the rotating shaft 901, and may also define the positions of the first rocker arm 6 and the first connecting portion 401.

In some embodiments, the first frame 1 and the base 5 are movably connected, as shown in fig. 1 and 3, the bed frame 100 further includes a linkage mechanism 10, the base 5, the first frame 1, the second frame 2, the third frame 3 and the fourth frame 4 are movably connected with the linkage mechanism 10, and when one of the first frame 1, the second frame 2, the third frame 3 and the fourth frame 4 is driven to move, the other frames move under the driving of the linkage mechanism 10, so that the linkage of the actions among the frames is realized through the linkage mechanism 10. The specific structure of the linkage 10 can be referred to the structure of the linkage in chinese patent CN115005630a, which is incorporated herein by reference in its entirety, so that the specific structure and connection relationship of the linkage 10 are not described herein. In other embodiments, the first frame 1 and the base 5 may be fixedly connected, and the third frame 3 and the fourth frame 4 and the second frame 2 are driven to move by two independent driving devices.

As shown in fig. 1 to 4, the bed frame 100 further includes a linear driving device 11, the linear driving device 11 is connected between the base 5 and the second frame 2, the linear driving device 11 is used for driving one frame of the first frame 2, the second frame 3 and the third frame 4 to move, and then the other two frames are driven to move through the linkage mechanism 10 to realize the change of the first use state and the second use state. In the figure, a linear driving device 11 is connected between the base 5 and the second frame 2, and drives the second frame 2 to move so as to drive other frames to move. The linear drive 11 can be operated in a telescopic manner in a linear direction, and the linear drive 11 is controlled in an electric (e.g. electric ram, electric cylinder), hydraulic (e.g. hydraulic cylinder), pneumatic (e.g. air cylinder) or manual (e.g. manual ram). Preferably, the linear driving device 11 is electric, and can work only by a power supply, so that the linear driving device is more convenient to use and has low noise.

Because the linkage mechanism 10 is adopted, the linkage of the frames can be realized by only one linear driving device 11, the number of the linear driving devices 11 is small, the total cost is greatly reduced, and meanwhile, the installation is more convenient because the space can be selected to be installed at a proper position. In addition, the reduction of the number of the linear driving devices 11 can reduce the weight of the bed frame and even the whole electric bed, and is more convenient to carry and install.

As shown in fig. 3, the base 200 includes two opposite supporting legs 2001, the two supporting legs 2001 are connected by a supporting bar 2002, and the base 5 is connected to the upper surfaces of the two supporting legs 2001. The length of the base 200 is smaller than that of the frame 100 to reduce the floor space and make full use of the space under the frame 100.

The utility model also proposes an electric bed comprising a bed frame 100 as described above. The electric bed also comprises a base 200, and the base 5 can be selectively and fixedly connected with the base 200.

The foregoing is merely exemplary of the utility model and other modifications can be made without departing from the scope of the utility model.
