Description

Technical Field

[0001] This application relates to the field of inflatable products, and particularly to an inflatable mattress. Background Art

[0002] Inflatable products such as inflatable mattresses and inflatable sofas are popular among people due to their light weight, convenience in packaging and storage. Taking an inflatable mattress as an example, as Figure 1 shown, the inflatable mattress includes a top sheet 191, a bottom sheet 192, a side sheet 193 extending circumferentially into a tubular shape, and a tension member 194. The upper end of the side sheet 193 is connected to the top sheet 191, and the lower end of the side sheet 193 is connected to the bottom sheet 192. The tension member 194 is inside the inflatable mattress and connects the top sheet 191 and the bottom sheet 192.

[0003] When manufacturing an inflatable mattress, the tubular side sheet cannot be folded into a planar shape for connection with the top sheet and the bottom sheet. Instead, it is necessary to manually put the side sheet on a mold to maintain its generally tubular shape; then, the top sheet and the bottom sheet are respectively connected to the upper end and the lower end of the side sheet. The manual operation in the manufacturing process results in a relatively high cost of the inflatable mattress and also a relatively high defective rate. Summary of the Utility Model

[0143] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0144] The inflatable mattress of the first embodiment

[0145] As Figure 2a And Figure 2bAs shown, the inflatable mattress 10 of the first embodiment is generally rectangular in shape and includes a first sheet 11, a second sheet 12, a first side sheet 14, a second side sheet 15, and a tension member 101. The second sheet 12 is opposite to and spaced apart from the first sheet 11 in the height direction H of the inflatable mattress 10. The first side sheet 14 and the second side sheet 15 are spaced apart in the width direction W of the inflatable mattress 10 and are connected between the first sheet 11 and the second sheet 12. The first sheet 11, the second sheet 12, the first side sheet 14, and the second side sheet 15 define an inflatable chamber 13 for inflation. It should be understood that the inflatable mattress 10 can also be configured in other shapes. For simplicity, in this application, the inflatable mattress 10 in a rectangular shape is taken as an example to describe the technical solution of this application. The first sheet 11 can be the top sheet of the inflatable mattress and is in contact with the user lying on the inflatable mattress. The second sheet can be the bottom sheet of the inflatable mattress and is in contact with the ground.

[0146] After the pressure of the gas (e.g., air) in the inflatable chamber 13 reaches the required value, the inflatable mattress 10 is in an inflated state and maintains a preset shape; when the gas in the inflatable chamber 13 is discharged, the inflatable mattress 10 is in a deflated state, and the volume of the inflatable mattress 10 is greatly reduced compared to its inflated state, thus facilitating the storage of the inflatable mattress 10.

[0147] As Figure 3a shown, the first sheet 11 is generally rectangular and includes a first side 111, a second side 112, a third side 113, and a fourth side 114. The first side 111 and the second side 112 of the first sheet are arranged opposite to each other, and the third side 113 and the fourth side 114 of the first sheet are arranged opposite to each other. For example, in the inflatable mattress 10, the first side 111 and the second side 112 of the first sheet extend along the length direction L of the inflatable mattress 10 (i.e., the first side 111 and the second side 112 of the first sheet form two length sides of the first sheet 11). The third side 113 and the fourth side 114 of the first sheet generally extend along the width direction W of the inflatable mattress 10 (i.e., the third side 113 and the fourth side 114 of the first sheet form two width sides of the first sheet 11).

[0148] Also as Figure 3aAs shown, the first sheet 11 further includes a first chamfered edge 115a, a second chamfered edge 115b, a third chamfered edge 115c, and a fourth chamfered edge 115d. The first chamfered edge 115a of the first sheet is connected between the first side 111 and the third side 113 of the first sheet. The second chamfered edge 115b of the first sheet is connected between the first side 111 and the fourth side 114 of the first sheet. The third chamfered edge 115c of the first sheet is connected between the second side 112 and the third side 113 of the first sheet. The fourth chamfered edge 115d of the first sheet is connected between the second side 112 and the fourth side 114 of the first sheet.

[0149] In one embodiment, the first chamfered edge 115a of the first sheet, the second chamfered edge 115b of the first sheet, the third chamfered edge 115c of the first sheet, and the fourth chamfered edge 115d of the first sheet are equal in length to each other.

[0150] Also as Figure 3a shown, the shape of the second sheet 12 is the same as the shape of the first sheet 11. For example, the second sheet 12 includes a first side 121, a second side 122, a third side 123, and a fourth side 124. The second sheet further includes a first chamfered edge 125a, a second chamfered edge 125b, a third chamfered edge 125c, and a fourth chamfered edge 125d.

[0151] The first side 121 of the second sheet is disposed opposite to the second side 122 of the second sheet, and the third side 123 of the second sheet is disposed opposite to the fourth side 124 of the second sheet. The first chamfered edge 125a of the second sheet is connected between the first side 121 and the third side 123 of the second sheet. The second chamfered edge 125b of the second sheet is connected between the first side 121 and the fourth side 124 of the second sheet. The third chamfered edge 125c of the second sheet is connected between the second side 122 and the third side 123 of the second sheet. The fourth chamfered edge 125d of the second sheet is connected between the second side 122 and the fourth side 124 of the second sheet.

[0152] In one embodiment, the first chamfered edge 125a of the second sheet, the second chamfered edge 125b of the second sheet, the third chamfered edge 125c of the second sheet, and the fourth chamfered edge 125d of the second sheet are respectively equal to the first chamfered edge 115a of the first sheet, the second chamfered edge 115b of the first sheet, the third chamfered edge 115c of the first sheet, and the fourth chamfered edge 115d of the first sheet. Thus, in the process of manufacturing the inflatable mattress 10, there is no need to distinguish between the first sheet 11 and the second sheet 12, which helps to simplify the manufacturing of the inflatable mattress 10.

[0153] In the inflatable mattress 10, the first side piece 14 is disposed along the length direction L of the inflatable mattress 10. Also asFigure 3a As shown, the first side piece 14 has a first edge 141 and a second edge 142. The first edge 141 of the first side piece is disposed opposite to the second edge 142 of the first side piece. The first side piece 14 further has a first end portion 143 and a second end portion 144 opposite to the first end portion 143.

[0154] At the first end portion 143 of the first side piece, there are a first bevel edge 145 and a third bevel edge 147. One end of the first bevel edge 145 of the first side piece is connected to the first edge 141 of the first side piece. The third bevel edge 147 of the first side piece is connected to the second edge 142 of the first side piece. The first bevel edge 145 of the first side piece is also equal to and connected to the third bevel edge 147 of the first side piece. The first bevel edge 145 of the first side piece is equal in length to the first chamfered edge 115a of the first sheet. The third bevel edge 147 of the first side piece is equal in length to the first chamfered edge 125a of the second sheet. Further, the first bevel edge 145 of the first side piece, the first chamfered edge 115a of the first sheet, the third bevel edge 147 of the first side piece, and the first chamfered edge 125a are equal in length.

[0155] In some embodiments, the first bevel edge 145 of the first side piece and the third bevel edge 147 of the first side piece form a first included angle α1. Optionally, the first included angle α1 of the first side piece may be less than or equal to 160°. Further, the first included angle α1 of the first side piece is a right angle. The first end portion 143 of the first side piece forms a generally pointed shape.

[0156] At the second end portion 144 of the first side piece, there are a second bevel edge 146 and a fourth bevel edge 148. The second bevel edge 146 of the first side piece is connected to the first edge 141 of the first side piece. The fourth bevel edge 148 of the first side piece is connected to the second edge 142 of the first side piece. The second bevel edge 146 of the first side piece is connected to the fourth bevel edge 148 of the first side piece. The second bevel edge 146 of the first side piece is equal in length to the second chamfered edge 115b of the first sheet. The fourth bevel edge 148 of the first side piece is equal in length to the second chamfered edge 125b of the second sheet. Further still, the second bevel edge 146 of the first side piece, the second chamfered edge 115b of the first sheet, the fourth bevel edge 148 of the first side piece, and the second chamfered edge 125b of the second sheet are equal in length.

[0157] In some embodiments, the second bevel edge 146 of the first side piece and the fourth bevel edge 148 of the first side piece form a second included angle α2. The second end portion 144 of the first side piece also forms a generally pointed shape. Optionally, the second included angle α2 of the first side piece may be less than or equal to 160°. Further, the second included angle α2 of the first side piece is a right angle.

[0158] The first side piece 14 also has a folding axis 149 extending along the length direction L of the inflatable mattress 10. The first side 141 of the first side piece, the first bevel edge 145 of the first side piece, and the second bevel edge 146 of the first side piece are on one side of the folding axis 149 of the first side piece; the second side 142 of the first side piece, the third bevel edge 147 of the first side piece, and the fourth bevel edge 148 of the first side piece are on the other side of the folding axis 149 of the first side piece. The parts of the first side piece 14 on both sides of the folding axis 149 are symmetric with respect to the folding axis 149. When the first side piece 14 is folded in half along the folding axis 149 of the first side piece, the first side 141 of the first side piece 14 is aligned with the second side 142 of the first side piece 14, the first bevel edge 145 of the first side piece 14 is aligned with the third bevel edge 147 of the first side piece 14, and the second bevel edge 146 of the first side piece 14 is aligned with the fourth bevel edge 148 of the first side piece 14.

[0159] In the inflatable mattress 10, the second side piece 15 is arranged along the length direction L of the inflatable mattress 10. The shape and size of the second side piece 15 are the same as those of the first side piece 14. In this way, during the manufacturing process of the inflatable mattress 10, there is no need to distinguish between the first side piece 14 and the second side piece 15, which also helps to simplify the manufacturing of the inflatable mattress 10. This embodiment exemplarily shows that the first side piece 14 and the second side piece 15 are arranged along the length direction L of the inflatable mattress 10. It can be understood that the first side piece 14 and the second side piece 15 can also be arranged along the width direction W of the inflatable mattress 10.

[0160] Specifically, the first side 151 of the second side piece 15 is arranged opposite to the second side 152 of the second side piece. The second side piece has a first end 153 and a second end 154 opposite to the first end 153.

[0161] At the first end 153 of the second side piece, there are a first bevel edge 155 and a third bevel edge 157. The first bevel edge 155 of the second side piece is connected to the first side 151 of the second side piece. The third bevel edge 157 of the second side piece is connected to the second side 152 of the second side piece. The first bevel edge 155 of the second side piece is also connected to the third bevel edge 157 of the second side piece. The first bevel edge 155 of the second side piece is equal in length to the third chamfered edge 115c of the first sheet. The third bevel edge 157 of the second side piece is equal in length to the third chamfered edge 125c of the second sheet. Further, the first bevel edge 155 of the second side piece, the third chamfered edge 115c of the first sheet, the third bevel edge 157 of the second side piece, and the third chamfered edge 125c of the second sheet are equal in length.

[0162] In some embodiments, the first bevel edge 155 of the second side piece and the third bevel edge 157 of the second side piece form a first included angle α3. The first end 153 of the second side piece forms a generally pointed shape. The first included angle α3 of the second side piece can be less than or equal to 160°. Further, the first included angle α3 of the second side piece can be a right angle.

[0163] At the second end portion 154 of the second side piece, there are a second bevel edge 156 and a fourth bevel edge 158. The second bevel edge 156 of the second side piece is connected to the first side 151 of the second side piece. The fourth bevel edge 158 of the second side piece is connected to the second side 152 of the second side piece. The second bevel edge 156 of the second side piece is also equal to and connected to the fourth bevel edge 158 of the second side piece. The second bevel edge 156 of the second side piece is equal in length to the fourth chamfered edge 115d of the first sheet. The fourth bevel edge 158 of the second side piece is equal in length to the fourth chamfered edge 125d of the second sheet. Further, the second bevel edge 156 of the second side piece, the fourth chamfered edge 115d of the first sheet are equal in length, the fourth bevel edge 158 of the second side piece, and the fourth chamfered edge 125d of the second sheet are equal in length.

[0164] In some embodiments, the second bevel edge and the fourth bevel edge of the second side piece form a second included angle α4. The second end portion 154 of the second side piece forms a generally pointed shape. The second included angle α4 of the second side piece can be less than or equal to 160°. Further, the second included angle α4 of the second side piece can be a right angle.

[0165] The second side piece 15 also has a folding axis 159 extending along the length direction L of the inflatable mattress 10. The first side 151 of the second side piece, the first bevel edge 155 of the second side piece, and the second bevel edge 156 of the second side piece are on one side of the folding axis 159 of the second side piece; the second side 152 of the second side piece, the third bevel edge 157 of the second side piece, and the fourth bevel edge 158 of the second side piece are on the other side of the folding axis 159 of the second side piece. The portions of the second side piece 15 on both sides of the folding axis 159 are symmetric with respect to the folding axis 159. When the second side piece 15 is folded in half along the folding axis 159, the first side 151 of the second side piece is aligned with the second side 152 of the second side piece, the first bevel edge 155 of the second side piece is aligned with the third bevel edge 157 of the second side piece, and the second bevel edge 156 of the second side piece is aligned with the fourth bevel edge 158 of the second side piece.

[0166] When manufacturing the inflatable mattress 10, as Figure 3b shown, the first sheet 11 and the second sheet 12 are stacked, and the first side piece 14 and the second side piece 15 are folded into a generally planar shape and placed between the first sheet 11 and the second sheet 12.

[0167] The first side piece 14 is folded along the folding axis 149 of the first side piece into a substantially planar shape such that the first side 141 of the first side piece is aligned with the second side 142 of the first side piece, the first beveled side 145 of the first side piece is aligned with the third beveled side 147 of the first side piece, and the second beveled side 146 of the first side piece is aligned with the fourth beveled side 148 of the first side piece. Additionally, the first side 141 of the first side piece is aligned with the first side 111 of the first sheet, the second side 142 of the first side piece is aligned with the first side 121 of the second sheet, the first beveled side 145 of the first side piece is aligned with the first chamfered side 115a of the first sheet, the second beveled side 146 of the first side piece is aligned with the second chamfered side 115b of the first sheet, the third beveled side 147 of the first side piece is aligned with the first chamfered side 125a of the second sheet, and the fourth beveled side 148 of the first side piece is aligned with the second chamfered side 125b of the second sheet.

[0168] The second side piece 15 is folded along the folding axis 159 of the second side piece into a substantially planar shape such that the first side 151 of the second side piece is aligned with the second side 152 of the second side piece, the first beveled side 155 of the second side piece is aligned with the third beveled side 157 of the second side piece, and the second beveled side 156 of the second side piece is aligned with the fourth beveled side 158 of the second side piece. Additionally, the first side 151 of the second side piece is aligned with the second side 112 of the first sheet, the second side 152 of the second side piece is aligned with the second side 122 of the second sheet, the first beveled side 155 of the second side piece is aligned with the third chamfered side 115c of the first sheet, the second beveled side 156 of the second side piece is aligned with the fourth chamfered side 115d of the first sheet, the third beveled side 157 of the second side piece is aligned with the third chamfered side 125c of the second sheet, and the fourth beveled side 158 of the second side piece is aligned with the fourth chamfered side 125d of the second sheet.

[0169] In this way, overall, the first side piece 14, the second side piece 15, the first sheet 11, and the second sheet 12 are all in a substantially planar state and are stacked. The welding equipment welds these sheets substantially on a plane. Thus, the mattress structure of this embodiment eliminates the step in the prior art of manually fixing the side pieces to the welding die in its manufacturing process, providing a basis for improving the automation degree of mattress manufacturing. After the welding operation is completed, the third side 123 of the second sheet is connected to the third side 113 of the first sheet, and the fourth side 124 of the second sheet is connected to the fourth side 114 of the first sheet. At the same time, the first side 141 of the first side piece is connected to the first side 111 of the first sheet, the second side 142 of the first side piece is connected to the first side 121 of the second sheet, the first hypotenuse 145 of the first side piece is connected to the first chamfered side 115a of the first sheet, the second hypotenuse 146 of the first side piece is connected to the second chamfered side 115b of the first sheet, the third hypotenuse 147 of the first side piece is connected to the first chamfered side 125a of the second sheet, and the fourth hypotenuse 148 of the first side piece is connected to the second chamfered side 125b of the second sheet. The first side 151 of the second side piece is connected to the second side 112 of the first sheet, and the second side 152 of the second side piece is connected to the second side 122 of the second sheet. The first hypotenuse 155 of the second side piece is connected to the third chamfered side 115c of the first sheet, the second hypotenuse 156 of the second side piece is connected to the fourth chamfered side 115d of the first sheet, the third hypotenuse 157 of the second side piece is connected to the third chamfered side 125c of the second sheet, and the fourth hypotenuse 158 of the second side piece is connected to the fourth chamfered side 125d of the second sheet.

[0170] Compared with the mattress structure of the prior art, the manufacturing process of the mattress structure of this embodiment eliminates the step of manually fixing the side pieces to the welding die, providing a basis for improving the automation degree of manufacturing the inflatable mattress 10. Subsequently, the number of personnel required for manufacturing the inflatable mattress 10 is reduced, thereby reducing the manufacturing cost of the inflatable mattress 10. Moreover, the errors caused by human factors are reduced, and thus the defective rate of the inflatable mattress is lowered.

[0171] In one embodiment, the first sheet 11, the second sheet 12, the first side sheet 14 and the second side sheet 15 are all made of a polymer material or a multi-layer composite material including a polymer material layer. For example, the polymer material may include, but is not limited to, one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic urethanes (TPU), polyethylene terephthalate (PET), ethylene-vinyl acetate (EVA) copolymer, and nylon. In this way, the first sheet 11, the second sheet 12, the first side sheet 14 and the second side sheet 15 can be welded together. The welding operation is simple and convenient, and the weld is not easily air-leaked. Of course, according to the actual situation, the first sheet 11, the second sheet 12, the first side sheet 14 and the second side sheet 15 can also be made of other materials and can be connected by other connection methods, which are not limited herein.

[0172] A plurality of tension members 101 are provided in the inflatable chamber 13 of the inflatable mattress 10 (as Figure 2a and Figure 2b shown). The tension members 101 are connected to the first sheet 11 and the second sheet 12 by high-frequency welding, hot melting, gluing or other connection methods. After the tension members 101 are tensioned, they provide a pulling force to the first sheet 11 and the second sheet 12 to limit the deformation of the inflatable mattress 10, so that the inflatable mattress 10 can maintain a preset shape after being inflated.

[0173] Optionally, the plurality of tension members 101 have different structures in different embodiments. For example, each tension member 101 is a sheet-like tension member 102 (as Figure 15 shown) or a linear tension member 103 (as Figure 16 and Figure 17 shown).

[0174] The sheet-like tension member 102 can have a single-layer or composite-layer structure according to actual needs.

[0175] When the sheet-like tension member 102 is a single-layer sheet material, it can be made of a polymer material, which can include but is not limited to one or several of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic urethanes (TPU), polyethylene terephthalate (PET), ethylene-vinyl acetate (EVA) copolymer, and nylon. Understandably, in some other embodiments, the main body of the single-layer sheet-like tension member 102 can also be made of other materials other than polymer materials, such as fabric materials, where the fabric materials can optionally be densely woven or formed into a mesh structure. The fabric materials can be but are not limited to natural fiber fabrics (such as, but not limited to, cotton fabrics, linen fabrics, wool fabrics, silk fabrics) or synthetic fiber fabrics (such as, but not limited to, polyester fiber fabrics, polyethylene fiber fabrics, polypropylene fiber fabrics).

[0176] When the sheet-like tension member 102 is a composite sheet material, it is composed of two or more layers of sheet materials bonded, welded, or otherwise combined, and each layer of the multi-layer sheet materials can be made of the above polymer materials or the above other materials respectively.

[0177] The linear tension member 103 includes one or more wire bodies, and these one or more wire bodies span the distance between the first sheet 11 and the second sheet 12 of the inflatable mattress 10 and are optionally parallel or substantially parallel in space. For example, these wire bodies are spaced apart from each other at equal distances or in a manner that changes according to a certain pattern. The material of one or more wire bodies in the linear tension member 103 can be but is not limited to natural fibers (such as, but not limited to, cotton fibers, linen fibers, wool fibers, silk fibers) or synthetic fibers (such as, but not limited to, polyester fibers, polyethylene fibers, polypropylene fibers). The linear tension member 103 is usually indirectly connected to the first sheet 11 and the second sheet 12 through a connector, and the connector can be made of a polymer material that is not limited to facilitating the welding of the first sheet 11 and the second sheet 12.

[0178] The inflatable mattress of the second embodiment

[0179] As Figure 4 、 Figure 5 and Figure 6a shown, the inflatable mattress of the second embodiment is similar to the inflatable mattress of the first embodiment. For simplicity, only the differences between the two will be described below.

[0180] AsFigure 6a As shown, the first sheet 11 is generally rectangular and includes a first side 111, a second side 112, a third side 113, and a fourth side 114. The first sheet 11 further includes a first chamfered side 115a, a second chamfered side 115b, a third chamfered side 115c, and a fourth chamfered side 115d. The first side 111 and the second side 112 of the first sheet extend along the length direction L of the inflatable mattress 10 (i.e., the first side 111 and the second side 112 of the first sheet form two length sides of the first sheet 11). The third side 113 and the fourth side 114 of the first sheet generally extend along the width direction W of the inflatable mattress 10 (i.e., the third side 113 and the fourth side 114 of the first sheet form two width sides of the first sheet 11).

[0181] The second sheet 12 includes a main body 20, a first side portion 21, and a second side portion 22. The main body 20 of the second sheet is generally rectangular. The width direction of the main body 20 generally follows the width direction W of the inflatable mattress 10, and the length direction of the main body 20 generally follows the length direction L of the inflatable mattress 10. The first side portion 21 and the second side portion 22 are connected to both sides of the main body 20 in the width direction. The first side portion 21 extends along the length direction of the main body. The second side portion 22 extends along the length direction of the main body. For example, there is a first folding axis 207 between the first side portion 21 and the main body 20, and a second folding axis 208 between the second side portion 22 and the main body 20. It can be understood that the first side portion 21 and the second side portion 22 can also be connected to both sides of the main body 20 in the length direction. That is, the first side portion 21 extends along the width direction of the main body. The second side portion 22 also extends along the width direction of the main body.

[0182] The main body 20 has a first side 201 and a second side 202 opposite to the first side 201. The first side 201 and the second side 202 of the main body are two width sides of the main body 20. In addition, the main body 20 further has a first chamfered side 203, a second chamfered side 204, a third chamfered side 205, and a fourth chamfered side 206. The first chamfered side 203 and the third chamfered side 205 of the main body are respectively connected to both ends of the first side 201 of the main body, and the second chamfered side 204 and the fourth chamfered side 206 of the main body are respectively connected to both ends of the second side 202 of the main body.

[0183] The first side portion 21 is similar to the first side piece 14 of the inflatable mattress of the first embodiment. For example, the first side portion 21 has a first side 211, as well as a first end 212 and a second end 213. The first end 212 of the first side portion includes a first bevel edge 214 and a third bevel edge 215 that are connected to each other. The first bevel edge 214 of the first side portion has the same length as the first chamfered edge 115a of the first sheet. The third bevel edge 215 of the first side portion has the same length as the first chamfered edge 203 of the second sheet. Further, the first bevel edge 214 of the first side portion, the first chamfered edge 115a of the first sheet, the third bevel edge 215 of the first side portion, and the first chamfered edge 203 of the second sheet have the same length.

[0184] In some embodiments, the first bevel edge 214 and the third bevel edge 215 of the first side portion form a first included angle β1, such that the first end 212 of the first side portion is generally pointed. Optionally, the first included angle β1 of the first side portion may be less than or equal to 160°. Further, the first included angle β1 of the first side portion is a right angle.

[0185] The second end 213 of the first side portion includes a second bevel edge 216 and a fourth bevel edge 217 that are connected to each other. The first bevel edge 214 of the first side portion and the second bevel edge 216 of the first side portion are respectively connected to both ends of the first side 211 of the first side portion. The second bevel edge 216 of the first side portion has the same length as the second chamfered edge 115b of the first sheet. The fourth bevel edge 217 of the first side portion has the same length as the second chamfered edge 204 of the second sheet. Further, the second bevel edge 216 of the first side portion, the second chamfered edge 115b of the first sheet, the fourth bevel edge 217 of the first side portion, and the second chamfered edge 204 of the second sheet have the same length.

[0186] In some embodiments, the second bevel edge 216 and the fourth bevel edge 217 of the first side portion form a second included angle β2, such that the second end 213 of the first side portion is generally pointed. Optionally, the second included angle β2 of the first side portion may be less than or equal to 160°. Further, the second included angle β2 of the first side portion is a right angle.

[0187] As Figure 6a shown in the embodiment, the first side portion 21 has a third folding axis 218 extending from the first end 212 to the second end 213. The portions of the first side portion 21 on both sides of the third folding axis 218 are symmetric to each other.

[0188] The shape of the second side portion 22 is the same as that of the first side portion 21. For example, the second side portion 22 has a first side 221, and a first end portion 222 and a second end portion 223. The first end portion 222 of the second side portion includes a first bevel edge 224 and a third bevel edge 225 that are connected to each other. The first bevel edge 224 of the second side portion is equal in length to the third chamfered edge 115c of the first sheet. The third bevel edge 225 of the second side portion is equal in length to the third chamfered edge 205 of the second sheet. Further, the first bevel edge 224 of the second side portion, the third chamfered edge 115c of the first sheet, the third bevel edge 225 of the second side portion, and the third chamfered edge 205 of the second sheet are equal in length.

[0189] In some embodiments, the first bevel edge 224 of the second side portion and the third bevel edge 225 of the second side portion form a third included angle β3, such that the first end portion 222 of the second side portion is generally in a sharp-corner shape. Optionally, the third included angle β3 of the second side portion can be less than or equal to 160°. Further, the third included angle β3 of the second side portion can be a right angle.

[0190] The second end portion 223 of the second side portion includes a second bevel edge 226 and a fourth bevel edge 227 that are connected to each other. The first bevel edge 224 of the second side portion and the second bevel edge 226 of the second side portion are respectively connected to both ends of the first side 221 of the second side portion. The second bevel edge 226 of the second side portion is equal in length to the fourth chamfered edge 115d of the first sheet. The fourth bevel edge 227 of the second side portion is equal in length to the fourth chamfered edge 206 of the second sheet. Further, the second bevel edge 226 of the second side portion, the fourth chamfered edge 115d of the first sheet, the fourth bevel edge 227 of the second side portion, and the fourth chamfered edge 206 of the second sheet are equal in length.

[0191] In some embodiments, the second bevel edge 226 of the second side portion and the fourth bevel edge 227 of the second side portion form a fourth included angle β4, such that the second end portion 223 of the second side portion is generally in a sharp-corner shape. Optionally, the fourth included angle β4 of the second side portion can be less than or equal to 160°. Further, the fourth included angle β4 of the second side portion can be a right angle.

[0192] As Figure 6a shown in the embodiment, the second side portion 22 has a fourth folding axis 228 extending from the first end portion 222 of the second side portion to the second end portion 223 of the second side portion. The portions of the second side portion 22 on both sides of the fourth folding axis 228 are symmetric to each other.

[0193] When manufacturing the inflatable mattress 10, combining Figure 6a and Figure 6b, the first side portion 21 is folded toward the main body 20 along the first folding axis 207 and the first side portion 21 is folded along the third folding axis 218. The second side portion 22 is folded toward the main body 20 along the second folding axis 208 and the second side portion 22 is folded along the fourth folding axis 228. The third hypotenuse 215 of the first side portion and the first chamfered edge 203 of the main body are adjacent and aligned, and the fourth hypotenuse 217 of the first side portion is adjacent and aligned with the second chamfered edge 204 of the main body. The third hypotenuse 225 of the second side portion is adjacent and aligned with the third chamfered edge 205 of the main body, and the fourth hypotenuse 227 of the second side portion is adjacent and aligned with the fourth chamfered edge 206 of the main body. In this way, the second sheet 12 is folded into a substantially planar shape. Then, the first sheet 11 and the second sheet 12 are stacked together such that the first side 201 of the main body is aligned with the third side 113 of the first sheet, the second side 202 of the main body is aligned with the fourth side 114 of the first sheet, the first side 211 of the first side portion is aligned with the first side 111 of the first sheet, the first side 221 of the second side portion is aligned with the second side 112 of the first sheet, the first hypotenuse 214 of the first side portion is aligned with the first chamfered edge 115a of the first sheet, the second hypotenuse 216 of the first side portion is aligned with the second chamfered edge 115b of the first sheet, the first hypotenuse 224 of the second side portion is aligned with the third chamfered edge 115c of the first sheet, and the second hypotenuse 226 of the second side portion is aligned with the fourth chamfered edge 115d of the first sheet. Overall, the first sheet 11 and the second sheet 12 are both in a substantially planar state and stacked, so that as long as the corresponding sides of the first sheet 11 and the second sheet 12 in the substantially planar state are welded. Similar to Embodiment 1, the mattress structure of this Embodiment 2 omits the step of manually fixing the side pieces to the welding die in the manufacturing process, greatly simplifies the welding process, and avoids errors caused by manual operation. After the welding equipment in the automated device welds the first sheet and the second sheet, the third hypotenuse 215 of the first side portion is connected to the first chamfered edge 203 of the main body, and the fourth hypotenuse 217 of the first side portion is connected to the second chamfered edge 204 of the main body. The third hypotenuse 225 of the second side portion is connected to the third chamfered edge 205 of the main body, and the fourth hypotenuse 227 of the second side portion is connected to the fourth chamfered edge 206 of the main body. The first side 201 of the main body is connected to the third side 113 of the first sheet, the second side 202 of the main body is connected to the fourth side 114 of the first sheet, the first side 211 of the first side portion is connected to the first side 111 of the first sheet, the first side 221 of the second side portion is connected to the second side 112 of the first sheet, the first hypotenuse 214 of the first side portion is connected to the first chamfered edge 115a of the first sheet, the second hypotenuse 216 of the first side portion is connected to the second chamfered edge 115b of the first sheet, the first hypotenuse 224 of the second side portion is connected to the third chamfered edge 115c of the first sheet, and the second hypotenuse 226 of the second side portion is connected to the fourth chamfered edge 115d of the first sheet.

[0194] In addition, in the inflatable mattress of the second embodiment, the number of seams in the inflatable mattress 10 is reduced, thereby simplifying the manufacture of the inflatable mattress 10 and helping to reduce manufacturing errors and the defective rate of the inflatable mattress 10. In addition, since the number of seams is reduced, there is no need to reserve connection margins for the seams when preparing materials, which further helps to improve the material utilization rate.

[0195] It should be understood that the first side portion 21 and the second side portion 22 may also be made of the same material as the first sheet 11. Or one of the first side portion 21 and the second side portion 22 is made of the same material as the first sheet, and the other of the first side portion 21 and the second side portion 22 is made of the same material as the second sheet. This will not be elaborated here.

[0196] Inflatable mattress of the third embodiment

[0197] The inflatable mattress of the third embodiment is similar to the inflatable mattress of the first embodiment. For simplicity, only the differences between the two will be described below.

[0198] As Figure 7 shown, the first side piece 14 includes a first sub-side piece 161 and a second sub-side piece 162. The first sub-side piece 161 and the second sub-side piece 162 have the same shape and equal size.

[0199] As Figure 8a shown, the first sub-side piece 161 includes the first side 141 of the first side piece, the first hypotenuse 145 of the first side piece, the second hypotenuse 146 of the first side piece, and the splicing edge 163. The two ends of the splicing edge 163 of the first sub-side piece are respectively connected to the first hypotenuse 145 and the second hypotenuse 146 of the first side piece. The second sub-side piece 162 includes the second side 142 of the first side piece, the third hypotenuse 147 of the first side piece, the fourth hypotenuse 148 of the first side piece, and the splicing edge 164.
