[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present utility model, "several" means more than one, "many" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0033] The mattress of the embodiment of the present application is described below with reference to the drawings of the specification. It should be noted that the thickness direction is shown in the up-down direction in the drawings, and the left-right direction is perpendicular to the up-down direction.

[0034] Reference Figures 1 to 3 According to the mattress of the embodiment of the utility model, the mattress comprises a first flexible pad 10 and a second flexible pad 20, both of which have a set thickness direction, the first flexible pad 10 comprises a first splicing structure 100, the first splicing structure 100 protrudes in a direction perpendicular to the thickness direction, the second flexible pad 20 comprises a second splicing structure 200, the second splicing structure 200 protrudes in a direction perpendicular to the thickness direction, the first splicing structure 100 and the second splicing structure 200 are overlapped in the thickness direction, and the first splicing structure 100 and the second splicing structure 200 are connected and fixed by a connecting structure. The first splicing structure 100 and the second splicing structure 200 overlap in the thickness direction, which is equivalent to having at least partial overlap in the thickness direction, realizing the functional transition of the first flexible pad 10 and the second flexible pad 20, reducing the abruptness during use, making the transition of the splicing area more natural, and improving the use effect.

[0035] On the other hand, during use, when the mattress is under pressure, the connection position of the first splicing structure 100 and the second splicing structure 200 will tend to separate in the left-right direction. The first splicing structure 100 and the second splicing structure 200 have a partial overlap in the up-down direction, which can increase the surface area of ​​the surface where the first splicing structure 100 and the second splicing structure 200 contact in the up-down direction. When there is a tendency to separate in the left-right direction, the increased surface area can provide friction to offset the component force in the left-right direction when the mattress is under pressure, thereby improving the connection strength of the first splicing structure 100 and the second splicing structure 200. Moreover, the cross-section of the first splicing structure 100 and the second splicing structure 200 at the end is not the mutual splicing surface of the two, which can improve the stability of the connection between the first splicing structure 100 and the second splicing structure 200 when the end position of the first splicing structure 100 or the second splicing structure 200 is under pressure.

[0036] Specifically, the first flexible pad 10 and the second flexible pad 20 are uniformly extended as a whole. In the first flexible pad 10, the dimension of the first splicing structure 100 in the thickness direction is smaller than the thickness dimension of the first flexible pad 10 as a whole, so as to form a relative protruding structure. In the second flexible pad 20, the dimension of the second splicing structure 200 in the thickness direction is smaller than the thickness dimension of the second flexible pad 20 as a whole, so as to form a relative protruding structure. Among them, the overlapping arrangement of the first splicing structure 100 and the second splicing structure 200 in the present application can be understood as the first splicing structure 100 and the second splicing structure 200 contacting and fitting each other, and being stacked in sequence in the thickness direction to form a transition structure arranged up and down.

[0037] Reference Figures 1 to 3 In some embodiments, the first splicing structure 100 includes a first main body 110, and the second splicing structure 200 includes a second main body 210. The first main body 110 is provided with a first overlapping surface 111, and the second main body 210 is provided with a second overlapping surface 211. The first overlapping surface 111 and the second overlapping surface 211 are in contact with each other. The first overlapping surface 111 and the second overlapping surface 211 in contact with each other can make the structure compact and provide a friction surface between the first main body 110 and the second main body 210. When there is a tendency of relative movement, the probability of relative slippage between the first main body 110 and the second main body 210 can be reduced by forming a friction force.

[0038] In some embodiments, the first overlapping surface 111 and the second overlapping surface 211 are set as horizontal planes perpendicular to the thickness direction, so that the first splicing structure 100 and the second splicing structure 200 are respectively rectangular protrusions, and the sum of the dimensions of the first splicing structure 100 and the second splicing structure 200 in the thickness direction is the same as the overall thickness dimension of the first flexible pad 10 and the second flexible pad 20 to form a mattress with uniform overall thickness.

[0039] In some embodiments, the first lap surface 111 and the second lap surface 211 are configured as inclined surfaces or curved surfaces, so that at least a portion of the first lap surface 111 and the second lap surface 211 is inclined in the thickness direction, so that the cross-sectional area of ​​the portion of the first body 110 facing the second body 210 along the thickness direction gradually decreases, and the cross-sectional area of ​​the side close to the second body 210 is smaller than the cross-sectional area of ​​the side away from the second body 210. So that the cross-sectional area of ​​the portion of the second body 210 facing the first body 110 along the thickness direction gradually decreases, and the cross-sectional area of ​​the side close to the first body 110 is smaller than the cross-sectional area of ​​the side away from the first body 110. The change in the cross-sectional area of ​​the first body 110 and the second body 210 can further achieve a uniform transition of the splicing area and improve the use effect.

[0040] The setting of the inclined surface can facilitate the gradual change of the cross-sectional area. The setting of the curved surface can further increase the contact area between the first overlapping surface and the second overlapping surface, so as to further enhance the friction effect and the limiting effect of mutual pulling, and further improve the connection stability.

[0041] Reference Figures 1 to 3 In some embodiments, the fixed connection between the first splicing structure 100 and the second splicing structure 200 can be achieved by plugging. The first splicing structure 100 includes a first main body 110, and the second splicing structure 200 includes a second main body 210. One of the first main body 110 and the second main body 210 is provided with a splicing portion 300, and the other is provided with a splicing groove 400. The splicing portion 300 is configured to be similar to the splicing groove 400, and the splicing portion 300 is inserted into the splicing groove 400. The splicing portion 300 and the splicing groove 400 form a connection structure to achieve plug-in fixation. Among them, the shape-matching setting can be understood as that the shape of the splicing portion 300 is the same as the shape of the splicing groove 400 and the size is adapted so that the splicing portion 300 can be inserted into the splicing groove 400 to achieve plug-in.

[0042] In some embodiments, the first body 110 and the second body 210 protrude in the left and right directions respectively, the first body 110 is stacked on the upper side of the second body 210, and the splicing portion 300 and the splicing groove 400 are both arranged on the side where the first body 110 and the second body 210 face each other. The cooperation between the splicing portion 300 and the splicing groove 400 can provide a limiting force along the left and right directions to improve the connection stability of the first flexible pad 10 and the second flexible pad 20.

[0043] Reference Figures 1 to 3In some embodiments, the first lap surface 111 may be provided with a splicing portion 300 and a splicing groove 400 at the same time, and the second lap surface 211 may be provided with a splicing portion 300 and a splicing groove 400 at the same time. The splicing portion 300 provided on the first lap surface 111 is configured to be in the same shape as the splicing groove 400 provided on the second lap surface 211, and the splicing portion 300 provided on the first lap surface 111 is inserted into the splicing groove 400 provided on the second lap surface 211. The splicing portion 300 provided on the second lap surface 211 is configured to be in the same shape as the splicing groove 400 provided on the first lap surface 111, and the splicing portion 300 provided on the second lap surface 211 is inserted into the splicing groove 400 provided on the first lap surface 111. The first body 110 and the second body 210 are respectively provided with a splicing groove 400 and a splicing part 300, and the splicing grooves 400 and the splicing parts 300 of the two are matched one by one, which can increase the connection nodes of the first splicing structure 100 and the second splicing structure 200, increase the connection strength, and evenly open the splicing grooves 400 on the first body 110 and the second body 210, so as to avoid that the structural strength difference between the first body 110 and the second body 210 is too large when a plurality of splicing grooves 400 are only provided on the first body 110 or only on the second body 210, and evenly strengthen the strength of the two, thereby reducing the probability of the first body 110 or the second body 210 breaking.

[0044] Further, in the first body 110, the splicing parts 300 and the splicing grooves 400 are alternately arranged on the first lap surface 111, and in the second body 210, the splicing parts 300 and the splicing grooves 400 are alternately arranged on the second lap surface 211. For example, the splicing parts 300 and the splicing grooves 400 can be alternately arranged along the extension direction of the first lap surface 111 or the second lap surface 211, so that the splicing parts 300 arranged on the second lap surface 211 correspond one-to-one with the splicing grooves 400 arranged on the first lap surface 111, and the splicing grooves 400 arranged on the second lap surface 211 correspond one-to-one with the splicing parts 300 arranged on the first lap surface 111. The alternately arranged splicing parts 300 and splicing grooves 400 can make the strength distribution of the first body 110 and the second body 210 more uniform, reduce stress concentration, and further reduce the risk of fracture. Among them, the present application does not make specific restrictions on the number of splicing parts 300 and splicing grooves 400. According to actual needs, on a single first body 110 and a single second body 210, the number of splicing parts 300 can be set to one, two or more, and the number of splicing grooves 400 can be set to one, two or more.

[0045] Reference Figures 1 to 3In some embodiments, the splicing part 300 includes a connector 330, a first protrusion 310, and a second protrusion 320. The connector 330 has a first end 331 and a second end 332 opposite to each other. The first end 331 is connected to the first body 110 or the second body 210. The first protrusion 310 and the second protrusion 320 are connected to the second end 332. The first protrusion 310 and the second protrusion 320 are arranged relative to each other with respect to the connector 330, that is, the first protrusion 310 and the second protrusion 320 are respectively located on opposite sides of the connector 330, and the opposite direction of the first protrusion 310 and the second protrusion 320 is perpendicular to the direction of the first end 331 toward the second end 332. The arrangement of the first protrusion 310 and the second protrusion 320 can increase the contact area when the splicing part 300 is inserted into the splicing groove 400, and the force is evenly applied, thereby reducing the probability of separation due to concentrated force.

[0046] Reference Figures 1 to 3 Furthermore, the outer surface of the first protrusion 310 is a curved surface, so that the first protrusion 310 can be inserted into the splicing groove 400 more smoothly, reducing the difficulty of assembly, and making the force on the first protrusion 310 more uniform. The smooth outer surface can also reduce the probability of damage and breakage under friction. Similarly, the outer surface of the second protrusion 320 can also be set as a curved surface, so that the second protrusion 320 can be inserted into the splicing groove 400 more smoothly, reducing the difficulty of assembly, and making the force on the second protrusion 320 more uniform. The smooth outer surface can also reduce the probability of damage and breakage under friction.

[0047] Reference Figure 4 and Figure 5 In other embodiments, in the first splicing structure 100, one end of the splicing part 300 is connected to the first body 110, and the other end of the splicing part 300 extends in a direction inclined to the first lap surface 111, so that the splicing part 300 is in a barb shape, and a splicing groove 400 is defined between the splicing part 300 and the first body 110. In the second splicing structure 200, one end of the splicing part 300 is connected to the second body 210, and the other end of the splicing part 300 extends in a direction inclined to the second lap surface 211, so that the splicing part 300 is in a barb shape, and a splicing groove 400 is defined between the splicing part 300 and the first body 110. By bending and extending the splicing part 300, the splicing groove 400 can be defined on the basis of forming a protruding structure for matching, so as to realize the connection between the first body 110 and the second body 210. Among them, the splicing part 300 can extend along a curve, an arc or a broken line segment, the curve and the arc are inclined to the first lap surface 111 or the second lap surface 211, and at least a part of the broken line segment is inclined to the first lap surface 111 or the second lap surface 211 to form a hook shape, and the splicing parts 300 of the first main body 110 and the second main body 210 can hook each other to achieve the effect of limiting and fixing.

[0048] Specifically, the first flexible pad 10 and the second flexible pad 20 can be made of sponges, respectively, to facilitate the processing of the connection structure of the first splicing structure 100 and the second splicing structure 200. In some embodiments, the first flexible pad 10 and the second flexible pad 20 have different hardnesses, for example, the hardness of the first flexible pad 10 is greater than the hardness of the second flexible pad 20, to meet different hardness requirements. For example, in a double bed, one of them likes a pad with a larger hardness, and the other likes a pad with a smaller hardness. For example, among users with special conditions such as waist injuries, when the waist injury occurs, it is necessary to sleep on a pad with a smaller hardness to relieve pain, and when it does not occur, it is necessary to sleep on a pad with a larger hardness to maintain the lumbar curvature. Among them, the hardness difference between the first flexible pad 10 and the second flexible pad 20 can be achieved by applying sponges of different materials, for example, selecting one of polyurethane, latex and memory foam respectively. The same material can also be used to achieve hardness differentiation by adjusting the density of the material.

[0049] In other embodiments, the first flexible pad 10 and the second flexible pad 20 have different thermal conductivities, for example, the thermal conductivity of the first flexible pad 10 is greater than the thermal conductivity of the second flexible pad 20 to meet different temperature requirements. For example, in different seasons, a pad with good thermal conductivity is needed in summer to quickly dissipate heat, and a pad with poor thermal conductivity is needed in winter to keep warm. For example, in double use, men and women have different body sensations of temperature, and women are relatively more afraid of cold. Therefore, men can use pads with better thermal conductivity and women can use pads with poor thermal conductivity to balance the difference in body sensation and ensure a good sleeping experience. Among them, the difference in thermal conductivity between the first flexible pad 10 and the second flexible pad 20 can also be achieved by using sponges of different materials or adjusting the density of the same material.

[0050] In addition to being applied to the above-mentioned double bed scenario (splicing the mattress in the width / left-right direction), the utility model can also be applied to other scenarios (splicing the mattress in the length / front-back direction). For example: due to the differences and variability in human body shape, weight, and height, different users have very different requirements for mattress performance. In order to match the mattress with the person's lying posture and body shape and to relax the muscles to the greatest extent, from an ergonomic point of view, different parts need to provide different support forces. Therefore, the mattress can be divided into the head and neck area, shoulder and back area, waist and hip area, calf area and foot area. Users can choose the head and neck area, shoulder and back area, waist and hip area, calf area and foot area with appropriate hardness and / or thermal conductivity according to their own needs, and use the structure of the utility model to splice any two adjacent areas in the head and neck area, shoulder and back area, waist and hip area, calf area and foot area, so as to achieve the adjustment of the hardness and / or thermal conductivity of the mattress.

[0051] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
