[0029] Reference below Figure 1-Figure 5 The adjustment mechanism 10 according to the embodiment of the present application is described.

[0030] According to the embodiment of the present application, the adjustment mechanism 10 includes: an adjustment plate 1, the adjustment plate 1 is suitable for being clamped between the mattress 300 and the bed frame 200, the adjustment plate 1 includes a first connecting plate 11 and a second connecting plate 12, the first connecting plate 11 is configured to be connected to a portion of the mattress 300 in the length direction, the second connecting plate 12 is configured to be connected to another portion of the mattress 300 in the length direction, and the second connecting plate 12 is rotatably connected to the first connecting plate 11, the first connecting plate 11 and / or the second connecting plate 12 is provided with a mounting groove 18, and an electric telescopic rod 14 is provided in the mounting groove 18, the electric telescopic rod 14 has a first state and a second state, in the first state, the electric telescopic rod 14 is received in the mounting groove 18, in the second state, the electric telescopic rod 14 extends out of the mounting groove 18 along its axis and abuts against the bed frame 200 so that the first connecting plate 11 and the second connecting plate 12 have a preset angle; wherein the free end 141 of the electric telescopic rod 14 is provided with a buffer structure 15.

[0031] Thus, the angle of a partial area of ​​the mattress 300 can be adjusted by extending and retracting the electric telescopic rod 14, so that the mattress 300 can adapt to different postures of the user, thereby improving the sleeping comfort of the user.

[0032] It is worth noting that the adjustment plate 1 of the adjustment mechanism 10 can be applied between the bed frame 200 and the mattress 300, or can also be applied between the sofa and the cushion, etc., which is not limited here.

[0033] For example Figure 1 As shown, the adjustment mechanism 10 can be applied between a bed frame 200 and a mattress 300, wherein Figure 1 As shown, the adjustment plate 1 includes a first connecting plate 11 and a second connecting plate 12, the first connecting plate 11 is configured to be connected to a portion of the mattress 300 in the length direction, the second connecting plate 12 is configured to be connected to another portion of the mattress 300 in the length direction, and the second connecting plate 12 is rotatably connected to the first connecting plate 11.

[0034] Furthermore, if Figure 2 As shown, the first connecting plate 11 and / or the second connecting plate 12 is provided with a mounting groove 18, and an electric telescopic rod 14 is provided in the mounting groove 18. The electric telescopic rod 14 has a first state and a second state. In the first state, the electric telescopic rod 14 is received in the mounting groove 18. In the second state, the electric telescopic rod 14 extends out of the mounting groove 18 along its axis and abuts against the bed frame 200 so that the first connecting plate 11 and the second connecting plate 12 have a preset angle; wherein, the free end 141 of the electric telescopic rod 14 is provided with a buffer structure 15.

[0035] In this way, when the electric telescopic rod 14 is in the first state, the electric telescopic rod 14 is located in the installation groove 18, so that the electric telescopic rod 14 does not occupy additional space, which is beneficial to reducing the volume of the adjustment mechanism 10 and facilitating the storage and transportation of the adjustment mechanism 10. When the electric telescopic rod 14 is in the second state, the electric telescopic rod 14 extends out of the installation groove 18 along its axis and abuts against the bed frame 200 so that the first connecting plate 11 and the second connecting plate 12 have a preset angle. In this way, the adjustment plate 1 drives the mattress 300 to bend at a preset angle to adapt to the user's posture.

[0036] It should be noted that, by providing a buffer structure 15 at the free end 141 of the electric telescopic rod 14 (that is, the end of the electric telescopic rod 14 that abuts against the bed frame 200 when the electric telescopic rod 14 is in the second state), when the free end 141 of the electric telescopic rod 14 abuts against the bed frame 200, there will be no rigid collision and thus no damage to the electric telescopic rod 14, thereby protecting the electric telescopic rod 14 and improving the service life of the electric telescopic rod 14.

[0037] The electric telescopic rod 14 may be a hydraulic telescopic mechanism or a pneumatic telescopic structure, which is not limited here.

[0038] For example, when the user leans against the head of the bed, the first connecting plate 11 is provided with a mounting groove 18, and the electric telescopic rod 14 in the mounting groove 18 can be extended to drive the first connecting plate 11 to rotate relative to the second connecting plate 12, so that the first connecting plate 11 will drive the part of the mattress 300 connected thereto to lift. At this time, the first connecting plate 11 and the second connecting plate 12 have a preset angle, that is, an angle is also formed between the front end of the mattress 300 in the length direction and the rear end of the mattress 300 in the length direction.

[0039] At this time, the mattress 300 can support the user's back, thereby adapting to the user's posture and improving the user's sleeping comfort.

[0040] The axis of the electric telescopic rod 14 is tangent to the movement direction of the first connecting plate 11 or the second connecting plate 12. In this way, it can be ensured that when the electric telescopic rod 14 is in the second state, it can stably support the first connecting plate 11 or the second connecting plate 12 to ensure its structural stability.

[0041] It is worth noting that since the adjustment mechanism 10 of the present application can be designed separately from the mattress 300, the adjustment mechanism 10 can be suitable for different user groups. In this way, some users do not need to replace the entire mattress 300. They only need to place the adjustment mechanism 10 between the mattress 300 and the bed frame 200, and connect the first connecting plate 11 and the second connecting plate 12 to different parts of the mattress 300 respectively, which makes its use cost lower and simple to operate, which is conducive to reducing costs.

[0042] According to the adjustment mechanism 10 of the embodiment of the present application, the adjustment plate 1 can be directly placed between the mattress 300 and the bed frame 200, and the first connecting plate 11 and the second connecting plate 12 can be fixed to the front half and the rear half in the length direction of the mattress 300 respectively. Then, the angle of a partial area of ​​the mattress 300 can be adjusted by extending and retracting the electric telescopic rod 14, so that the mattress 300 can adapt to different postures of the user, thereby improving the user's sleeping comfort.

[0043] In some embodiments, the first connecting plate 11 and the second connecting plate 12 are each provided with at least one electric telescopic rod 14. Thus, the first connecting plate 11 can realize its rotation relative to the second connecting plate 12 by utilizing the extension and retraction of the corresponding electric telescopic rod 14, thereby realizing the bending of one part of the mattress 300 relative to another part, so as to meet the use needs of the user and thus improve the sleeping comfort of the user.

[0044] Alternatively, the second connecting plate 12 can be rotated relative to the first connecting plate 11 by utilizing the extension and retraction of the corresponding electric telescopic rod 14, thereby realizing the bending of another part of the mattress 300 relative to one part, so as to meet the user's usage needs and thereby improve the user's sleeping comfort.

[0045] Accordingly, the first connecting plate 11 and the second connecting plate 12 can be rotated simultaneously by using the corresponding electric telescopic rods 14, thereby meeting the user's usage needs and improving the user's sleeping comfort.

[0046] In some embodiments, the buffer structure 15 includes an elastic member 151, which is embedded in the free end 141, and the outer end of the elastic member 151 is protruded from the free end 141. As a result, the elastic member 151 can occupy a smaller space, which is conducive to realizing its miniaturized design, and the outer end of the elastic member 151 is protruded from the free end 141, so that when the electric telescopic rod 14 switches from the first state to the second state, the outer end of the elastic member 151 will contact the bed frame 200 earlier than the free end 141 of the electric telescopic rod 14. In this way, the elastic member 151 can be used to play a buffering role, and when the user lifts part of the mattress 300, the elastic member 151 can also be used to play a certain buffering role to prevent the electric telescopic rod 14 from being damaged due to excessive force.

[0047] In some embodiments, the outer end of the elastic member 151 is sleeved with an anti-skid pad 16. Thus, by providing the anti-skid pad 16, the free end 141 of the electric telescopic rod 14 is prevented from sliding, so that when the electric telescopic rod 14 supports the first connecting plate 11 and / or the second connecting plate 12, the stability of the free end 141 of the electric telescopic rod 14 can be ensured, thereby ensuring the stability of the adjustment mechanism 10 in use.

[0048] In some embodiments, Figure 3 As shown, the elastic member 151 is configured as a spring, thereby making the structure of the elastic member 151 simpler, helping to reduce the difficulty of setting the elastic member 151 and helping to reduce the cost.

[0049] In some embodiments, Figure 4 As shown, the buffer structure 15 includes a rubber pad 17, and the rubber pad 17 is coated on the free end 141. As a result, the rubber pad 17 can occupy a smaller space, which is conducive to realizing its miniaturized design, and the outer end of the rubber pad 17 is protruding from the free end 141, so that when the electric telescopic rod 14 switches from the first state to the second state, the outer end of the rubber pad 17 will contact the bed frame 200 earlier than the free end 141 of the electric telescopic rod 14. In this way, the rubber pad 17 can be used to play a buffering role, and when the user lifts part of the mattress 300, the rubber pad 17 can also be used to play a certain buffering role to prevent the electric telescopic rod 14 from being damaged due to excessive force.

[0050] At the same time, the friction force of the rubber pad 17 is relatively large, which is convenient for preventing the free end 141 of the electric telescopic rod 14 from sliding, so that when the electric telescopic rod 14 supports the first connecting plate 11 and / or the second connecting plate 12, the stability of the free end 141 of the electric telescopic rod 14 can be ensured, thereby ensuring the stability of the use of the adjustment mechanism 10, and the structure of the rubber pad 17 is simpler, which is conducive to reducing the difficulty of setting the elastic member 151 and reducing costs.

[0051] In some embodiments, Figure 2 As shown, the first connecting plate 11 and the second connecting plate 12 are rotatably connected via a rotating shaft 13. Therefore, by setting the first connecting plate 11 and the second connecting plate 12 to be rotatably connected via the rotating shaft 13, it is ensured that when one of the first connecting plate 11 and the second connecting plate 12 rotates relative to the other, its rotational freedom is high, thereby avoiding the problem of its rotation being stuck.

[0052] In some embodiments, the first connecting plate 11 and / or the second connecting plate 12 are provided with a pressure sensor, and the pressure sensor is electrically connected to the electric telescopic rod 14. Therefore, by providing the pressure sensor, the pressure at the corresponding first connecting plate 11 and / or the second connecting plate 12 can be judged by the pressure sensor, and then it can be judged whether the electric telescopic rod 14 needs to be controlled to extend, so as to improve its automation.

[0053] For example, pressure sensors are provided on both the first connecting plate 11 and the second connecting plate 12. When a user sits on the mattress 300, if the user sits on the part of the mattress 300 corresponding to the second connecting plate 12, at this time, the pressure sensor at the second connecting plate 12 detects pressure, and the electric telescopic rod 14 on the second connecting plate 12 can be controlled to be in the first state. At this time, the pressure sensor at the first connecting plate 11 does not detect pressure, and the electric telescopic rod 14 on the second connecting plate 12 can be controlled to switch from the first state to the second state, so that the part of the mattress 300 corresponding to the first connecting plate 11 can be raised to a predetermined angle. At this time, the user can choose whether to lean on the part of the mattress 300 corresponding to the first connecting plate 11 according to needs, thereby improving the user's comfort.

[0054] Of course, when the user sits on the part of the mattress 300 corresponding to the first connecting plate 11, a process similar to the above process can also be performed and the same effect can be achieved, which will not be described in detail here.

[0055] In some embodiments, there are multiple pressure sensors and multiple electric telescopic rods 14, and the multiple pressure sensors correspond to the multiple electric telescopic rods 14. Therefore, the pressure at the part of the mattress 300 corresponding to the corresponding electric telescopic rods 14 can be detected by multiple pressure sensors, thereby facilitating the improvement of its control accuracy.

[0058] Therefore, the control device 20 can be used to control the electric telescopic rod 14, thereby improving its automation level. The control device 20 can be a remote controller or a software program, etc., which is not limited here.

[0059] According to the sleep improvement device 100 of the embodiment of the present application, its adjustment mechanism 10 can directly place the adjustment plate 1 between the mattress 300 and the bed frame 200, and fix the first connecting plate 11 and the second connecting plate 12 to the front half and the rear half in the length direction of the mattress 300 respectively, and then the angle of a partial area of ​​the mattress 300 can be adjusted by the extension and retraction of the electric telescopic rod 14, so that the mattress 300 can adapt to different postures of the user, thereby improving the user's sleeping comfort.
