[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] like Figures 1 to 7As shown, this utility model discloses a height-adjustable folding bed, including a folding bed body, a lifting mechanism, and a first adjustment mechanism. The lifting mechanism is connected to the folding bed body and drives the folding bed body to rise and fall. The folding bed body is mounted on two front support legs 1 and two rear support legs 3. Specifically, the folding bed body is hinged to the front support legs 1 and the rear support legs 3 respectively. A front support foot 2 is hinged to the lower end of the front support leg 1, and a rear support foot 4 is hinged to the lower end of the rear support leg 3. Furthermore, rollers are installed inside the rear support foot 4 to make the folding bed body more stable during lifting, tilting, and other movements. To ensure a smooth and stable experience, the folding bed body is equipped with a headrest inner frame 8, a seat inner frame 10, and a leg inner frame 11. The seat inner frame 10 is mounted on the folding bed body. The headrest inner frame 8 and the leg inner frame 11 are hinged to the folding bed body. The first adjustment mechanism includes a second electric support rod 14 and a third electric support rod 15, both mounted on the folding bed body. The output end of the second electric support rod 14 is hinged to the leg inner frame 11, and the output end of the third electric support rod 15 is hinged to the headrest inner frame 8. When the second electric support rod 14 is working, it drives the leg inner frame 11 to rotate relative to the seat inner frame 10, thus raising or lowering the legs. When the third electric support rod 15 is working, it drives the headrest inner frame 8 to rotate relative to the seat inner frame 10, thus raising or lowering the backrest. By setting up the first adjustment mechanism, the angles of the back and legs can be adjusted separately, improving user comfort.

[0026] Furthermore, the leg inner frame 11 includes a first inner frame 11.1 and a second inner frame 11.2. One end of the first inner frame 11.1 is hinged to the folding bed body, and the other end is hinged to the output end of the second inner frame 11.2 and the second electric support rod 14. When the second electric support rod 14 is working, it can not only realize the function of raising the legs, but also realize the function of bending the legs, further improving the comfort of use.

[0027] In this embodiment, the folding bed body specifically includes a head outer frame 5, a seat outer frame 9, and a leg outer frame 7. The head inner frame 8 is hinged to the head outer frame 5. The head outer frame 5 is hinged to one end of the seat outer frame 9 via a front hinge pin 20. The leg inner frame 11 is hinged to the leg outer frame 7. Specifically, the first inner frame 11.1 is hinged to the leg outer frame 7, and the leg outer frame 7 is hinged to the other end of the seat outer frame 9 via a rear hinge pin 22. When the folding bed body is unfolded, a detachable first safety pin 25 is installed on the head outer frame 5 and the seat outer frame 9, and a detachable second safety pin 26 is installed on the leg outer frame 7 and the seat outer frame 9 to prevent the folding bed from folding backwards, ensuring the stability and safety of the folding bed.

[0028] When the folding bed is folded, detachable locking pins 21 are installed between the head frame 5 and the seat frame 9, and between the leg frame 7 and the seat frame 9. Detachable locking pins 23 are installed on the front support leg 2 and the front support leg 1, and on the rear support leg 4 and the rear support leg 3. Locking pins 21 and 23 lock the folding bed to prevent it from opening accidentally, making it safer to transport, fold, and store.

[0029] Furthermore, the inner frame 10 of the seat is installed on the outer frame 9 of the seat. By setting the folding bed to a three-section structure, it is convenient to fold the folding bed, reduce the space occupied, and facilitate storage and transportation.

[0030] The height-adjustable folding bed also includes a lifting mechanism, which comprises a first electric support rod 13 and a fourth electric support rod 16. The first electric support rod 13 is mounted on the rear support leg 3, and its output end is hinged to the leg outer frame 7. The fourth electric support rod 16 is mounted on the front support leg 1, and its output end is hinged to the head outer frame 5. Furthermore, rollers are installed inside the rear support leg 4 to facilitate adjustment of the distance between the front support leg 1 and the rear support leg 3. When the height of the folding bed needs to be adjusted, the output ends of the first electric support rod 13 and the fourth electric support rod 16 extend simultaneously to the same length, applying a reaction force to the front support leg 1 and the rear support leg 3 to adjust the distance between them, thereby adjusting the height of the folding bed. After the height of the folding bed is adjusted, a first safety pin 25 and a second safety pin 26 are installed to ensure the stability of the folding bed. When the output ends of the first electric support rod 13 and the fourth electric support rod 16 extend to different lengths, the tilt angle of the folding bed body can be adjusted to meet the needs of different user positions, further improving user comfort.

[0031] In this embodiment, specifically, a headboard 6 is installed on the outer head frame 5 and / or a footboard 12 is installed at the end of the inner leg frame 11, so as to protect the head and feet and improve the safety of use.

[0032] In this embodiment, specifically, mounting holes 24 are provided on both sides of the head inner frame 8 and / or the leg inner frame 11, and detachable handrails 19 are installed in the mounting holes 24. The handrails 19 are plugged into the mounting holes 24, which improves the convenience of assembly. Depending on the usage, the handrails 19 can be installed in different positions, which improves the convenience of using the handrails 19.

[0033] The height-adjustable folding bed also includes a first auxiliary support 17 and a second auxiliary support 18. One end of the first auxiliary support 17 is hinged to the rear support leg 3, and the other end is hinged to the leg outer frame 7. The hinge point between the first auxiliary support 17 and the leg outer frame 7 is located near the seat outer frame 9. One end of the second auxiliary support 18 is hinged to the front support leg 1, and the other end is hinged to the head outer frame 5. The hinge point between the second auxiliary support 18 and the head outer frame 5 is located near the seat outer frame 9. This enhances the load-bearing strength of the folding bed and further improves its stability and safety during use.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
