[0043] Embodiment 1

[0044] Please refer to Figures 1 to 7 On the one hand, an embodiment of the utility model provides a mattress 100, which includes a support frame 1, an elastic cord 2, at least one hardness adjustment mechanism 3 and a mattress body unit 4. Among them, the support frame 1 has two long frames 11, and two short frames 12 connecting the two ends of the two long frames 11. Specifically, the lengths of the long frames 11 and the short frames 12 can also be equal, which is not limited here. The inner sides of the two long frames 11 and the two short frames 12 are enclosed to form a accommodating area 13. Specifically, the support frame 1 needs to have a certain supporting strength for supporting the elastic cord 2, the hardness adjustment mechanism 3, the mattress body unit 4 and the human body. Optionally, the support frame 1 can be made of alloy or wood. A plurality of elastic cords 2 are arranged at intervals along the length direction of the mattress 100, and have a first end 21 fixedly connected to the inner side of the long frame 11 of the support frame 1, and a second end 22 opposite to the first end 21. The specific structure of the elastic cord 2 is prior art and will not be elaborated here, as long as it can play the role of elastically supporting the mattress body unit 4 and has a certain elastic deformation ability in the length direction. The hardness adjustment mechanism 3 is arranged on a side frame of the support frame 1 away from the first end 21 of the elastic cord, and includes a driving member and a displacement assembly 32. Among them, the driving member is arranged on a side frame of the support frame 1 away from the first end 21 of the elastic cord; the displacement assembly 32 is connected to the output shaft 311 of the driving member, and can move linearly along the width direction of the mattress 100 in the accommodating area 13. The second end 22 of the elastic cord 2 is connected to the displacement assembly 32; the mattress body unit 4 is mounted on the upper end of the elastic cord 2. Specifically, the width of the mattress body unit 4 is slightly shorter than the length of the elastic cord 2, so as to leave a certain installation and movement space for the hardness adjustment mechanism 3 to avoid interference.

[0045] In this way, the mattress 100 can adjust the tightness of the elastic cord 2 through the hardness adjustment mechanism 3, thereby adjusting the elasticity of the mattress 100.

[0046] Optionally, see Figure 5In this embodiment, the driving member is a driving motor 31, and its output shaft 311 is connected to the displacement assembly 32 through a transmission assembly 33. Specifically, in this embodiment, the driving motor 31 can be selected as a stepping motor. In this way, the driving motor 31 can better control the forward and reverse rotations of its output shaft 311, as well as the forward and reverse rotation angles, so as to more accurately adjust the displacement of the displacement assembly 32, and then adjust the elasticity of the elastic cord 2. Furthermore, the mattress 100 also includes a controller (not shown in the figure), and the controller is electrically connected to the driving member of the hardness adjustment mechanism 3. In this way, the movement of the driving motor 31 can be accurately controlled by the controller.

[0047] Optionally, see Figure 5 In this embodiment, the transmission assembly 33 includes an output gear 331 fixed to the output shaft 311 of the driving motor 31, and a rack 332 meshing with the output gear 331. In this way, the transmission ratio between the driving motor 31 and the displacement assembly 32 can be further adjusted by the transmission ratio of the output gear 331 and the rack 332, so as to improve the accuracy of the displacement assembly 32 moving along the width direction of the mattress 100 in the accommodating area 13, thereby adjusting the tightness accuracy of the elastic cord 2, and further adjusting the accuracy of the elastic strength of the mattress 100. Of course, in other embodiments, the transmission assembly 33 may only include the output gear 331, and the output gear 331 is directly connected to the displacement assembly 32 for transmission, which is not specifically limited here.

[0048] Optionally, see Figure 5 In this embodiment, the displacement assembly 32 includes a screw 321 and a displacement gear 322; wherein the screw 321 is fixed on the support frame 1, and is arranged at intervals along the length direction of the mattress 100, and corresponds to the elastic cord 2 one by one. A plurality of displacement gears 322 correspond to the screw 321 one by one, and are threadedly connected to the screw 321. A displacement gear 322 is meshed and connected with a rack 332, and two adjacent displacement gears 322 are meshed and connected, and the thread rotation directions of two adjacent screws 321 are opposite. That is, in this embodiment, the rack 332 is a double-sided rack with a certain width, that is, one tooth surface of the rack 332 is meshed with the output gear 331, and the other tooth surface of the rack 332 is meshed with the displacement gear 322. The second end 22 of the elastic cord 2 is fixedly connected to the displacement gear 322 of the displacement assembly 32. Since the two adjacent displacement gears 322 are meshed, and the thread rotation directions of the two adjacent screws 321 are opposite. In this way, the displacement gears 322 can be displaced in the same direction, so as to adjust the tightness of the elastic rope at the same time. In this embodiment, one displacement gear 322 at the end is meshed with the rack 332. Of course, in other embodiments, two adjacent displacement gears 322 in the middle may be meshed with the rack 332 at the same time, and no specific limitation is made here.

[0049] To improve the comfort of the mattress 100, please refer to Figure 6 Preferably, the mattress body unit 4 is provided with a first surface pad layer 41 and a surface pleated cotton layer 42 in sequence from bottom to top, the first surface pad layer 41 includes a cotton felt layer 411, a first non-woven fabric layer 412, a first sponge layer 413, and a latex layer 414 in sequence from bottom to top; the surface pleated cotton layer 42 includes a second non-woven fabric layer 421, a second sponge layer 422, a third sponge layer 423 and a spray-bonded cotton layer 424 in sequence from bottom to top.

[0050] In order to improve the overall aesthetics of the mattress 100, please refer to Figure 1 Preferably, the mattress 100 further comprises a surface cloth jacket 5 which is sleeved on the outside of the support frame 1 and the mattress body unit 4. In the present embodiment, the surface cloth jacket 5 may be a whole, with its side opening and connected by a zipper (not shown in the figure). Of course, in other embodiments, the surface cloth jacket 5 may also be an upper cloth jacket 5 (not shown in the figure) and a lower cloth jacket 5 (not shown in the figure), which are connected by a zipper. Preferably, in order to provide a certain supporting force to the elastic cord 2 and the mattress body unit 4 so as to extend the time for the elastic cord 2 to reach the fatigue limit, in the present embodiment, a second surface padding layer 43 is provided between the lower side of the elastic cord 2 and the surface cloth jacket 5. Specifically, the second surface padding layer 43 may also be a cotton felt layer 411.

[0051] Embodiment 2

[0052] This embodiment is basically the same as the first embodiment, and the difference lies only in the specific structure of the hardness adjustment mechanism 3. That is, in this embodiment, the driving member is a driving motor, and the displacement assembly 32 includes a screw (not shown in the figure) and a screw nut (not shown in the figure). Among them, the screw is rotatably arranged on the support frame 1, and is arranged at intervals along the length direction of the mattress 100, and corresponds to the elastic rope 2 one by one. Specifically, a part of the screw is a bare rod, and the bare rod part is rotatably arranged on the support frame 1 through a bearing (not shown in the figure). The screw nut and the screw are matched accordingly. The above-mentioned screws are all connected to the output shaft of the driving motor in a transmission manner, and the second end 22 of the elastic rope 2 is fixedly connected to the screw nut of the displacement assembly 32. Preferably, the displacement assembly 32 may also include a slide groove (not shown in the figure) fixedly arranged on the support frame 1, having an outer shape and a part of the outer circumference of the screw nut. In this way, the tightness of the elastic rope 2 can also be adjusted by the hardness adjustment mechanism 3, thereby adjusting the elasticity of the mattress 100.

[0053] Embodiment 3

[0054] This embodiment is basically the same as the first embodiment, and the only difference is the specific structure of the hardness adjustment mechanism 3. That is, in this embodiment, the driving member is a cylinder (not shown in the figure), the displacement assembly 32 is a telescopic block (not shown in the figure) connected to the output shaft of the cylinder, and the second end 22 of the elastic cord 2 is fixedly connected to the telescopic block. In this way, the tightness of the elastic cord 2 can also be adjusted by extending or extending the cylinder, thereby adjusting the elasticity of the mattress 100.

[0055] Embodiment 4

[0056] This embodiment is basically the same as the first embodiment, and the only difference is the specific structure of the hardness adjustment mechanism 3. That is, in this embodiment, the driving member is an electric cylinder (not shown in the figure), the displacement assembly 32 is a telescopic block (not shown in the figure) connected to the output shaft of the cylinder, and the second end 22 of the elastic cord 2 is fixedly connected to the telescopic block. In this way, the tightness of the elastic cord 2 can also be adjusted by extending or extending the electric cylinder, thereby adjusting the elasticity of the mattress 100.

[0057] Embodiment 5

[0058] Please refer to Figure 7 , this embodiment is basically the same as the first embodiment, the only difference is that the mattress 100 can adjust the elasticity in different regions in the length direction. Specifically, the mattress 100 is divided into a first region a, a second region b, a third region c, a fourth region d and a fifth region e in the length direction; specifically, according to the body curve of the human body, the first region a of the mattress 100 corresponding to the cervical spine and above, the second region b of the mattress 100 corresponding to the thoracic spine, the third region c of the mattress 100 corresponding to the lumbar spine, the fourth region d of the mattress 100 corresponding to the buttocks to the thigh, and the fifth region e of the mattress 100 corresponding to the calf. Corresponding to the first region a, the second region b, the third region c, the fourth region d and the fifth region e, the mattress 100 is provided with five hardness adjustment mechanisms 3. The second ends 22 of the elastic cords 2 corresponding to the first region a, the second region b, the third region c, the fourth region d and the fifth region e are respectively connected to the displacement components 32 of the corresponding hardness adjustment mechanisms 3. In this way, different elasticities can be adjusted according to different areas, and the same area can be adjusted to the same elasticity, so that the softness and hardness of the entire mattress 100 conforms to the curve of the body. In this way, not only can the user sleep comfortably and improve the quality of sleep, but also the body curve will not be out of place or deformed, ensuring the health of the cervical, spinal and lumbar vertebrae.

[0059] Another embodiment of the present invention provides a bed (not shown in the figure), including a bed frame and the above-mentioned mattress 100 located on the bed frame. Since the bed has all the structures and connection relationships of the mattress, it has all the advantages of the mattress, which will not be described in detail here.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
