Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0031] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0032] See also Figure 1 The present application discloses a shape memory alloy mattress 100, which includes a shape memory alloy layer 1, a heating layer 2 and a temperature sensing layer 3. The shape memory alloy layer 1 includes a first side 1a and a second side 1b along its own thickness direction, the heating layer 2 is arranged on the first side 1a, and the temperature sensing layer 3 is arranged on the second side 1b. In other words, along the thickness direction of the shape memory alloy layer 1, from top to bottom, the temperature sensing layer 3, the shape memory alloy layer 1 and the heating layer 2 are respectively arranged. Among them, the shape memory alloy layer 1 can be deformed in response to changes in temperature, the heating layer 2 can be electrically connected to heat the shape memory alloy layer 1, so that the shape memory alloy layer 1 is deformed by heat, and the temperature sensing layer 3 is configured to monitor the heating temperature of the heating layer 2.

[0033] in, Figure 1 The direction indicated by X is the thickness direction of the shape memory alloy layer 1 or the shape memory alloy mattress 100. It can be understood that the above directions are only examples for ease of understanding and do not limit the scope of this embodiment.

[0034] The shape memory alloy mattress 100 disclosed in the present application utilizes the property that shape memory alloy can deform in response to temperature changes, so that the collapsed mattress after long-term use can be restored and rebounded. Exemplarily, the shape memory alloy mattress 100 of the present application has a shape memory alloy with a one-way memory effect, which is formed at a high temperature (e.g., 50°C-90°C) and then applied to the shape memory alloy layer 1 of the present application. At room temperature and without external force, the shape memory alloy layer 1 remains in a fixed state. When the user sleeps on the mattress and causes the shape memory alloy layer 1 to deform and collapse, the user can heat the shape memory alloy layer 1 back to 50°C-90°C through the heating layer 2, and the shape memory alloy in the shape memory alloy layer 1 will return to the state of being fixed at this temperature. In this way, the shape memory alloy layer 1 will return to the state before collapse. It can be seen that the present application utilizes the heating layer 2 to heat the shape memory alloy layer 1 to its deformation temperature, so that a mattress that collapses after use can be restored to its pre-collapse state, thereby avoiding the problem that the mattress cannot be restored to its original shape due to deformation and collapse caused by long-term use by the user.

[0035] In addition, the heating layer 2 can also heat the mattress, so that the mattress maintains a comfortable temperature in cold weather. Considering the need to prevent the heating temperature from being too high during heating and heat preservation, the present application also uses a temperature sensing layer 3 to monitor the heating temperature of the heating layer 2 in real time, so that the user can understand the actual heating temperature of the mattress, and the temperature of the heating layer 2 can be controlled through a separately installed control module to prevent the heating layer 2 from being too high, thereby improving the user's safety and user experience.

[0036] It is understandable that, generally speaking, the second side 1b is the side close to the human body. Therefore, the present application sets the temperature sensing layer 3 on the second side 1b. The temperature sensing layer 3 can monitor the human body surface temperature while monitoring the heating temperature of the heating layer 2, so as to assist the control module in adjusting the heating temperature of the heating layer 2 according to the human body surface temperature, so as to make the heating temperature of the heating layer 2 more suitable for the needs of the human body. For example, in winter, the user's body surface temperature is low, and the heating layer 2 can be heated up to adapt to the human body surface temperature under the control of the control module. When the user's body surface temperature rises and does not need an excessively high temperature temporarily, the heating temperature of the heating layer 2 can be appropriately reduced or maintained at a certain suitable temperature.

[0037] Optionally, the heating layer 2 of the present application may be connected to electricity through a power source provided by itself or connected to an external power source, etc., and the present application does not make any specific limitation thereto.

[0038] Optionally, the heating method of the heating layer 2 of the present application can be, for example, resistance wire heating or electromagnetic induction heating, etc. In order to facilitate understanding of the specific implementation of the present application, the electromagnetic induction heating is taken as an example for description below.

[0039] In some embodiments, the heating layer 2 may be an electromagnetic induction heating layer. It is understandable that an electromagnetic induction coil is provided in the electromagnetic induction heating layer 2, and after the electromagnetic induction coil is energized, it can generate an eddy current effect with the metal within the electromagnetic induction range to heat the metal. Shape memory alloy is used in the shape memory alloy layer 1 of the present application, and the electromagnetic induction heating layer 2 can generate an eddy current effect with the shape memory alloy, thereby achieving heating of the shape memory alloy. Since the electromagnetic induction heating method directly acts on the shape memory alloy through the eddy current effect, the fabric between the electromagnetic induction coil and the shape memory alloy has little effect on the heating, thereby reducing the heat loss of heating, which is beneficial to improving the heating effect of the heating layer 2 on the shape memory alloy layer 1.

[0040] See also Figure 2 In some embodiments, the shape memory alloy layer 1 includes two connecting plates 11 and a plurality of shape memory alloy wires 12. The two connecting plates 11 are spaced apart along the thickness direction of the shape memory alloy mattress 100. Each shape memory alloy wire 12 is disposed within the space. Both ends of the shape memory alloy wire 12 are respectively connected to the two connecting plates 11, and each shape memory alloy wire 12 is spaced apart. On the one hand, since the shape memory alloy is a metal material, it is necessary to consider the comfort of sleep when arranging the shape memory alloy in the mattress. However, the shape memory alloy wire 12 has the softness of a filamentous object, the elasticity and ductility of a metal, and has a certain deformation ability. Therefore, using the shape memory alloy wire 12 as the filler of the shape memory alloy layer 1 is conducive to ensuring the softness and elasticity of the mattress, so that the shape memory alloy mattress 100 has better sleep comfort. Secondly, the shape memory alloy wires 12 are arranged at intervals to prevent the shape memory alloy wires 12 from being arranged too densely, thereby avoiding affecting the air permeability of the mattress. When the mattress is in use, the shape memory alloy wires 12 will deform, and the intervals between the shape memory alloy wires 12 can leave deformation space for the shape memory alloy wires 12. Thirdly, the shape memory alloy wires 12 arranged at intervals are conducive to a good air permeable environment in the shape memory alloy layer 1, and the heating layer 2 heats the shape memory alloy layer 1 to form a high temperature environment, which can effectively inhibit bacteria in the shape memory alloy layer 1.

[0041] Optionally, the shape memory alloy wire 12 is wound into a spring shape in the thickness direction of the mattress, or a plurality of shape memory alloy wires 12 are bundled into a shape memory alloy wire cluster and then wound into a spring shape, and then connected and installed with the connecting plate 11. In the actual setting, a single shape memory alloy wire 12 is relatively soft and easy to deform, so that its supporting effect in the shape memory alloy layer 1 is relatively weak, which is not conducive to the supporting effect of the supporting surface of the shape memory alloy layer 1 on the human body. Based on this, winding the shape memory alloy wire 12 into a spring shape by a single shape memory metal wire can not only improve the elasticity of the shape memory alloy wire 12, but also from the cross-sectional shape in the thickness direction of the mattress, the cross-section of the spring-shaped shape memory alloy wire 12 increases after winding. Therefore, winding the shape memory alloy wire 12 into a spring shape is conducive to improving its supporting effect on the shape memory alloy layer 1 in the thickness direction. Similarly, bundling a plurality of shape memory alloy wires 12 into a shape memory alloy wire cluster and then winding it into a spring shape can also improve the supporting effect of the shape memory alloy layer 1.

[0042] Optionally, the two connecting plates 11 sandwich a plurality of shape memory alloy wires 12 in the middle to prevent the shape memory alloy wires 12 from moving freely between the two connecting plates 11. Specifically, the connecting plate 11 is provided with a plurality of limiting holes 11a, and each limiting hole 11a is configured to install a corresponding shape memory alloy wire 12. The present application fixes the position of the shape memory alloy wire 12 on the connecting plate 11 through the limiting holes 11a. When the shape memory alloy wire 12 is moved or deformed by an external force, the shape memory alloy wire 12 is only moved within the position range limited by the limiting holes 11a, and cannot move freely in the space between the two connecting plates 11, which is conducive to the shape memory alloy layer 1 maintaining a certain shape without causing arbitrary deformation. In addition, as another example, when the shape memory alloy wire 12 is wound into a spring shape, the shape memory alloy wire has a plurality of annular portions along its own thickness direction, so a hook can be provided on the connecting plate 11, and any annular portion can be hooked by the hook to fix the shape memory alloy wire. Alternatively, the shape memory alloy wire 12 may be integrally formed with the connecting plate 11 , so that the shape memory alloy wire 12 is fixed on the connecting plate 11 .

[0043] In order to increase the sleeping feeling of the mattress and enhance the user's experience, in some embodiments, the mattress further includes a filling layer 4 (please refer to Figure 3 ). The present application adjusts the overall sleeping feeling of the shape memory alloy mattress 100 by adding a filling layer 4, thereby improving the user's comfort.

[0044] Optionally, the filling material in the filling layer 4 may be latex, sponge, cotton, etc., which is not specifically limited in the present application.

[0045] In some examples, the filling layer 4 is disposed between the shape memory alloy layer 1 and the heating layer 2 along the thickness direction of the mattress. Since the heating layer 2 of the present application is an electromagnetic induction heating layer 2, the shape memory alloy layer 1 can be heated in the air by utilizing the eddy current effect. Therefore, the filling layer 4 can be disposed between the shape memory alloy layer 1 and the heating layer 2. Since the interval heating distance of the electromagnetic induction heating layer 2 is limited, the thickness of the filling layer 4 can be 2cm-7cm, specifically 2cm, 3cm, 4cm, 5cm, 6cm and 7cm, etc., which is not specifically limited in the present application.

[0046] In other examples, the filling layer 4 is disposed below the heating layer 2 along the thickness direction of the mattress. Considering that the heating layer 2 may directly heat the shape memory alloy layer 1 by using a resistance wire, in order to avoid the filling layer 4 affecting the heating effect of the heating layer 2 on the shape memory alloy layer 1, the filling layer 4 may be disposed below the heating layer 2. In this way, if the induction heating effect of the electromagnetic induction heating layer 2 is weak, arranging the filling layer 4 below the heating layer 2 can also avoid the influence of the filling layer 4 on the heating effect of the heating layer 2.

[0047] See also Figure 3 The present application also discloses a bed, which includes a bed frame 200 and a shape memory alloy mattress 100 in any of the above embodiments, and the mattress is arranged on the bed frame 200. Among them, a control module is provided on the bed frame 200, and the control module is electrically connected to the temperature sensing layer 3 of the mattress and the heating layer 2 of the mattress. The control module is configured to control the heating temperature of the heating layer 2 according to the monitored temperature of the temperature sensing layer 3. Exemplarily, the control module can be a main board, which can analyze the monitored temperature of the temperature sensing layer 3. If the monitored temperature of the temperature sensing layer 3 is too high or too low, and the temperature environment may cause discomfort to the human body, the control module sends a control signal to the heating layer 2 to adjust the heating temperature of the heating layer 2. In this way, the intelligent temperature control of the shape memory alloy mattress 100 is realized, and the overall intelligence of the bed is improved.

[0048] In some embodiments, the control module includes a control circuit board (not shown) and a control button 201 electrically connected to the control circuit board. A display panel 202 is also provided on the bed frame 200. The display panel 202 is electrically connected to the control circuit board. The display panel 202 is configured to display the heating temperature. The control button 201 is configured to control the heating layer 2 to start or stop heating. The control circuit board is configured to control the heating temperature of the heating layer 2 according to the monitored temperature of the temperature sensing layer 3.

[0049] Exemplarily, when the user needs to control the heating temperature of the heating layer 2, the control circuit board can control the heating temperature of the heating layer 2 according to the detected temperature of the temperature sensing layer 3, or, a plurality of control buttons 201 are used, wherein a part of the control buttons 201 can control the heating temperature of the heating layer 2, for example, heating up the deformed shape memory alloy mattress 100 to restore it to its original state, and another part of the control buttons 201 can control the activation of the heating function of the heating layer 2 or the activation of the monitoring function of the temperature sensing layer 3. At the same time, when the user uses the control button 201, the temperature number displayed on the display panel 202 can be used to understand the operation of the control button 201 on the heating layer 2 and the temperature sensing layer 3. In this way, the present application improves the temperature controllability of the mattress through the display panel 202 and the control button 201, and is also convenient for user operation.

[0050] Optionally, the display panel 202 and the control button 201 are arranged on the side of the bed frame 200. It is understandable that the bed frame 200 usually includes a head, a side, a foot, and a bed screen arranged on the head. Users usually get into bed from the side of the foot or the side. Therefore, the display panel 202 and the control button 201 are arranged on the side of the bed frame 200 where the user often passes by, such as the foot or the side. In this way, it is convenient for the user to control the temperature sensing layer 3 and the heating layer 2 of the mattress when passing by or getting into bed.

[0051] The shape memory alloy mattress and bed disclosed in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the shape memory alloy mattress and bed of the present application, and its core concept; at the same time, for those skilled in the art, according to the concept of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
