[0021] By adopting the above technical solution, when the height of the bed frame 2 needs to be adjusted, the second motor 14 is started, and the bed frame 2 is driven to slide up and down along the support 1 through the lifting component; when the auxiliary support leg 4 needs to be extended, the first motor 6 is started, the main gear 7 drives the secondary gear 8 and the rotating shaft 3 to rotate, and the auxiliary support leg 4 rotates out of the mounting cavity to support the bed frame 2; the positioning component is used to fix the position of the table 9, which facilitates the use of the table 9 and meets the needs of flexible space utilization and multi-functional use.

[0022] In this embodiment, the lifting assembly includes a first screw 13 rotatably installed in the bracket 1, a second motor 14 connected to the upper end of the first screw 13 is provided on the top of the bracket 1, a lifting frame 15 is screwed onto the first screw 13, a pair of longitudinally arranged guide grooves 16 are provided on the side wall of the bracket 1, a pair of guide blocks 17 are slidably provided in the pair of guide grooves 16, one end of the guide block 17 is fixedly connected to the lifting frame 15, and the other end is fixedly connected to the bed frame 2.

[0023] By adopting the above technical solution, the second motor 14 starts and drives the first screw 13 to rotate. The lifting frame 15, which is screwed to the first screw 13, slides up and down along the bracket 1 with the cooperation of the guide block 17 and the guide groove 16, thereby driving the bed frame 2 to rise and fall synchronously.

[0024] In this embodiment, the positioning component includes a mounting groove 18 located at one end of the bed frame 2. A positioning plate 19 is slidably disposed in the mounting groove 18. A transverse groove 20 communicating with the mounting groove 18 is provided on the lower wall of the bed frame 2. A driving block 21 is slidably disposed in the transverse groove 20.

The detailed connection methods are well-known in the field. The working principle and process are mainly described below.

[0031] Example: During the day, when the bed frame 2 is not in use, the second motor 14 can be started. The second motor 14 drives the first screw 13 to rotate. Under the guidance of the guide block 17 and the guide groove 16, the lifting frame 15 slides upward along the side wall of the support 1 until the bed frame 2 slides to the top. Then the motor is turned off. At this time, the auxiliary support leg 4 is stored in the installation cavity to avoid affecting the utilization of the space under the bed. At this time, the table 9 can be pulled down to separate it from the bed frame 2. The table is pulled down to a suitable height. Turn the knob, and the second screw 22 drives the drive block 21 and the positioning plate 19 to move, so that the positioning plate 19 is inserted into the corresponding positioning groove 23 on the side wall of the support 1, fixing the table 9. At this time, you can study or work on the table 9. After use, turn the knob in the opposite direction to separate the positioning plate 19 from the positioning groove 23 and lift the table 9. At this time, the magnetic strips 24 on both sides of the upper wall of the table 9 and the magnetic strips 24 on the lower wall of the bed frame 2 attract each other, so that the table 9 is attached to the bottom of the bed frame 2.

[0032] When the bed frame 2 needs to be used at night, the first motor 6 is started, the main gear 7 drives the secondary gear 8 and the rotating shaft 3 to rotate, the auxiliary support leg 4 rotates out of the mounting cavity through the strip groove 5 and rotates to the vertical position, the second motor 14 is started, which drives the bed frame 2 to the bottom. At this time, the bottom of the auxiliary support leg 4 contacts the ground and provides auxiliary support. At this time, the user can rest and sleep on the bed frame 2, which is convenient to use.
