[0002] With the increasing aging of the population and the growing demand for medical care, mattresses with assistive sitting functions are being used more and more widely in home care, elderly care institutions and medical institutions.

[0003] While existing sit-up mattresses can assist users in transitioning from a lying to a sitting position through backrest adjustment, there is still room for improvement in terms of structural stability, user comfort, and space adaptability.

[0004] Therefore, there is an urgent need to propose an improved and upgraded type of mattress for getting up. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a new type of mattress for getting up, which can achieve smooth getting up, comprehensive support and strong durability.

[0006] To achieve the above objectives, this utility model provides a get-up mattress, comprising:

[0007] A backplate base frame, with a backplate top frame located on top of the backplate base frame;

[0008] The backplate is divided into a front frame and a rear frame. The rear frame is fixed to the backplate base frame. The width of the front frame is greater than that of the rear frame, and they partially intersect. The front frame and the rear frame are rotatably connected by a lock nut and an internal hex screw. The front frame can rotate axially around the pivot point.

[0009] An electric actuator is mounted on the back frame and is connected to the front frame via a transmission.

[0010] Preferably, both the front frame and the rear frame are made of rigid frames, and the surface of the frames is covered with a rigid mesh structure.

[0011] Preferably, a lifting arm is provided between the back plate base and the front frame, and the electric push rod is connected to the front frame via the lifting arm.

[0012] Preferably, the lifting arm includes an integrally formed first link and a second link, with an included angle between the first link and the second link, and the center of the included angle is rotatably connected to the back plate base frame through a structural component;

[0013] The fixed end of the electric push rod is hinged to the back plate base frame, and the output rod of the electric push rod is hinged to the end of the first connecting rod.

[0014] The end of the second link is provided with a roller, and the lower surface of the front frame has a channel steel parallel to the length direction of the mattress, with the roller located in the channel steel to form rolling contact.

[0015] Preferably, the back panel base frame is provided with a soft sealing strip edge, and the soft sealing strip edge is close to the connection point between the front frame and the rear frame, in order to reduce the rigid contact between the front frame and the back panel base frame.

[0035] This utility model proposes a mattress for getting up, such as... Figures 1 to 3 As shown, it includes:

[0036] The back panel base frame 1 and the upper back panel frame 2 are divided into a front frame 21 and a rear frame 22.

[0037] The rear frame 22 is fixedly connected to the back plate base frame 1 (by welding or bolting).

[0038] The front frame 21 is wider than the rear frame 22, and the two are partially intersected and formed a rotating connection by a locking nut 23 and an internal hex screw 24: the smooth section (unthreaded part) of the internal hex screw 24 serves as the rotation axis, and the locking nut 23 only restricts axial displacement, allowing the front frame 21 to rotate axially around the rotation point (radial rotation clearance is retained).

[0039] Both the front frame 21 and the rear frame 22 are made of rigid frames (aluminum alloy or steel), and the surface of the frames is covered with a rigid mesh structure (plastic mesh or metal mesh) to balance support strength and breathability.

[0040] like Figure 1 and Figure 2 As shown, the electric push rod 3 is installed on the back plate base frame 1 and is connected to the front frame 21 via the lifting arm 4.

[0041] The lifting arm 4 is a first connecting rod 41 and a second connecting rod 42 integrally formed, and the angle between the two is rotatably connected to the structural components of the back plate base frame 1 through a bushing / bearing;

[0042] The fixed end of the electric push rod 3 is hinged to the back plate base frame 1, and the output rod is hinged to the end of the first connecting rod 41.

[0043] The end of the second link 42 is provided with a roller 43, and the lower surface of the front frame 21 is provided with a channel steel 211 parallel to the length direction of the mattress. The roller 43 is embedded in the channel steel 211 to form rolling contact (when getting up, the roller 43 rolls along the channel steel 211 to assist the front frame 21 to rotate smoothly).

[0044] like Figures 1 to 3 As shown, the soft sealing strip 5 is set on the back panel base frame 1, near the connection point between the front frame 21 and the rear frame 22. It is made of rubber / silicone material to reduce the rigid contact between the front frame 21 and the back panel base frame 1 when the front frame 21 falls back (reducing noise and wear).

[0045] Foldable support armrests 7: Distributed along the length of the mattress on both sides of the backrest base frame 1, connected by hinges, they can be folded for storage (close to the base frame to save space) or unfolded for support (covering the entire process of getting up and providing continuous gripping points).

[0046] like Figure 4 and Figure 5 As shown, the sponge pad 6 covers the upper surface of the back panel 2, and the lower surface has straps 62 (elastic bands or Velcro) at the four corners, which are attached to the four corners of the back panel 2 to ensure that the sponge pad 6 does not shift when the back panel rotates.

[0047] The lower surface of the sponge pad 6 has grooves 61, which correspond to the rotation points of the front frame 21 and the rear frame 22. By locally reducing the thickness of the sponge, the bending stress during the rotation of the back plate is dispersed, thus preventing the sponge from cracking.

[0048] like Figure 6 As shown, the roller 43 is located at the end of the second connecting rod 42 and is connected by a cotter pin 431, a cylindrical pin 432 and a washer 433. The washer 433 has a reserved gap to ensure that the roller 43 can rotate flexibly. The cotter pin 431 is inserted into the positioning hole of the cylindrical pin 432 to prevent the roller 43 from falling off.

[0049] The above-mentioned solutions can be specifically adopted as follows:

[0050] The rear frame 22 is fixed to the back plate base frame 1 by bolts; the connecting holes of the front frame 21 and the rear frame 22 are aligned, and after the hexagonal screw 24 is inserted, the bare rod section (length ≥ connecting thickness) serves as the rotation axis, and the locking nut 23 is tightened to fit (not locked, leaving a radial gap of 0.1~0.5mm) to ensure that the front frame 21 can rotate freely.

[0051] The lifting arm 4 is rotatably connected to the back plate base frame 1 at the included angle axis via a copper sleeve (for reducing friction);

[0052] The hinge seat of the electric push rod 3 and the hinge hole of the first connecting rod 41 are both equipped with bearings to reduce rotational resistance;

[0053] The roller 43 is made of nylon (wear-resistant and noise-reducing). After being embedded in the channel steel 211, it maintains a gap of 0.2~0.3mm with the inner wall of the channel to ensure smooth rolling.

[0054] The slot 61 of the sponge pad 6 is formed by molding or laser cutting, and its position is precisely corresponding to the rotation point of the front frame 21 and the rear frame 22. The radius of the rounded corner of the slot 61 is adjusted according to the thickness of the sponge. When the thickness is 60mm, the depth of the slot 61 is 10~15mm, which achieves "local weakening and stress dispersion".

[0055] The folding auxiliary armrest 7 is connected to the back panel base frame 1 via a damping hinge. When unfolded, it maintains stable support (damping provides positioning force), and when folded, it can fit snugly against the base frame, integrating with the appearance of the bed frame.

[0056] Workflow:

[0057] When the user stands up, the electric push rod 3 extends, pushing the first connecting rod 41, causing the lifting arm 4 to rotate around its axis. The roller 43 at the end of the second connecting rod 42 rolls along the length of the channel steel 211, causing the front frame 21 to rotate upward around the bare section of the hexagonal screw 24, thus lifting the front of the backrest frame 2 and assisting the user in changing from a lying to a sitting position. When the electric push rod 3 retracts, the front frame 21 falls back, and the soft sealing strip edge 5 makes contact to reduce noise.

[0058] When the back panel rotates, the sponge pad 6 bends as the angle between the front frame 21 and the rear frame 22 changes. The sponge at the groove 61 is weakened locally and naturally shrinks to disperse stress, avoiding the "piling up and wrinkling" or "tearing" of traditional sponges.

[0059] Before getting up, unfold the folding armrests that are distributed along the length of the bed, allowing users to continuously grip and gain leverage from the shoulders, waist, and other positions; after getting up, fold the armrests for storage, without obstructing getting out of bed or tidying the sheets.
