Detailed Implementation

[0023] See Figures 1-5 A bed frame with lifting function includes a bed frame body 1, support rods 13, bed board 5, mounting plate 2, lifting assembly, support plate 7, guide rod 71, wedge block 8, spring 9, electric push rod 2 10, and contact plate 11. The bed board 5 is located on the top of the bed frame body 1. Three support rods 13 for supporting the bed board 5 are connected from front to back in the upper part of the bed frame body 1. Mounting plates 2 are connected to the middle of the front and rear sides of the bed frame body 1. Lifting assemblies for driving the bed board 5 to rise and fall are provided on both mounting plates 2. The lifting assembly includes an electric push rod 1 6, a connecting rod 3, a rotating rod 31, and a connecting plate 4. The electric push rod 1 6 is hinged to the left side of both mounting plates 2. The connecting rod 3 is hinged to the middle of both mounting plates 2. The rotating rod 31 is hinged to the right side of both mounting plates 2. The lower end of both rotating rods 31 is connected to a protruding rod. The telescopic rods of push rod 16 are rotatably connected to the protruding rods on the two rotating rods 31 respectively. The two connecting plates 4 are respectively hinged to the rotating rods 31 and connecting rods 3 on the front and rear sides. The upper end of the connecting plate 4 is connected to the bed board 5. The bottom inner side of the bed box body 1 is fixedly connected to the front and rear support plates 7. The two support plates 7 are slidably connected to the upper and lower guide rods 71. The upper and lower guide rods 71 ​​are connected to the wedge block 8. The lower part of the two rotating rods 31 is provided with a slot 12 that cooperates with the wedge block 8. The guide rods 71 ​​are fitted with springs 9. The two ends of the springs 9 are respectively connected to the support plates 7 and the wedge block 8. The inner walls of the front and rear sides of the bed box body 1 are connected to electric push rods 20. The two electric push rods 20 are located under the mounting plate 2. The right side of the two wedge blocks 8 is connected to the contact plate 11. The telescopic rods of the two electric push rods 20 are in contact with the two contact plates 11 respectively.

[0024] When the user needs to store items inside the bed frame 1, the telescopic rods of the two electric push rods 6 extend synchronously, pushing the protruding rod of the corresponding rotating rod 31. This drives the rotating rod 31 to rotate around the hinge point of the mounting plate 2. The rotating rod 31 causes the connecting plate 4 to move upward, and the connecting plate 4 synchronously pulls the connecting rod 3 to rotate, thereby smoothly pushing the bed board 5 to rise, achieving automatic lifting of the bed board 5. When the rotating rod 31 rotates to contact the inclined surface of the wedge block 8, the rotating rod 31 squeezes the wedge block 8 to move laterally, causing the wedge block 8 to push the guide rod 71 to move and compress the spring 9. When the slot 12 of the rotating rod 31 aligns with the wedge block 8, the spring 9 rebounds, pushing the wedge block 8 into the slot 12 of the rotating rod 31, achieving self-locking of the bed board 5, preventing the bed board 5 from accidentally falling during operation, and ensuring user safety. After the user has finished storing items, the telescopic rods of the two electric push rods 10 extend, pushing the corresponding contact plate 11 to move laterally. The contact plate 11 causes the wedge block 8 to disengage from the slot 12, and the spring 9 is compressed again. Then, the telescopic rods of the two electric push rods 6 retract, pulling the rotating rod 31 to rotate and reset, thereby pulling the connecting plate 4 to lower the bed board 5 onto the bed frame body 1. The bed board 5 is supported by the support rod 13, realizing the automatic lifting function of the bed board 5. Finally, the telescopic rods of the two electric push rods 10 retract, and the spring 9 extends, pushing the wedge block 8 to move and reset the contact plate 11.

[0025] See Figure 2 It also includes a partition 15. The bottom inner side of the bed box body 1 is connected to two partitions 15, one in front and one in back. The partition 15 is used to cover and protect the lifting component. The partition 15 separates the storage space and the lifting component into independent areas, effectively preventing stored items from interfering with the operation of the lifting component.

[0026] See Figure 6 It also includes a breathable filter 16. There are three ventilation holes on the left and right sides of the bottom of the bed box body 1. Each ventilation hole is connected to a breathable filter 16. The ventilation holes and the breathable filter 16 enable air circulation inside and outside the bed box body 1, effectively preventing moisture accumulation and odor generation inside the bed box body 1.

[0027] See Figure 2 It also includes sound-absorbing cotton 14. All three support rods 13 are wrapped with sound-absorbing cotton 14, which can reduce the noise during the process of the bed board 5 descending to the support rods 13.
