[0042] To make the purpose, technical solutions and advantages of the present utility model clearer, the implementation manners of the present utility model will be further described in detail below with reference to the drawings.

[0043] Such as Figure 1 and Figure 2As shown, it is a perspective view of the bottom surface of a vehicle-mounted inflatable mattress 10 and a side cross-sectional view of the vehicle-mounted inflatable mattress 10. Specifically, Figure 1 The X direction and the Y direction shown therein are the width direction and the length direction of the vehicle-mounted inflatable mattress 10 respectively. The vehicle-mounted inflatable mattress 10 includes a mattress portion 12 and a support portion 14. Among them, the mattress portion 12 includes a bottom wall 122 and a face wall 124, and the bottom wall 122 and the face wall 124 are connected to form a first inflatable chamber 126, that is, the inflatable chamber of the mattress portion 12. A plurality of drawstrings 128 are arranged in the first inflatable chamber 126, and each drawstring 128 is welded to the bottom wall 122 and the face wall 124 respectively. After the drawstring 128 is tensioned, it provides a pulling force to the bottom wall 122 and the face wall 124 to limit the deformation of the mattress portion 12, so that the mattress portion 12 can maintain a preset shape after being inflated. The support portion 14 is connected to the bottom wall 122 of the mattress portion 12 to support the mattress portion 12. Figure 3 It shows a scenario where the vehicle-mounted inflatable mattress 10 is used on the vehicle seat. That is, first, the front row seat 30 in the vehicle is laid down, and then one end of the vehicle-mounted inflatable mattress 10 including the support portion 14 is abutted against the rear row seat 20, so as to stably place the vehicle-mounted inflatable mattress 10 on the two rows of seats in the vehicle for the user to lie on. Optionally, the shape of the support portion 14 can be a wedge shape adapted to the vehicle rear row seat 20, or other shapes, which are not specifically limited herein; in addition, the number of the support portions 14 is not limited either, and can be 1, 2 or more than 2. In addition, the setting position of the support portion 14 is not limited, and can be in the front, rear, left, right or middle of the bottom wall 122 of the mattress portion 12.

[0044] Next, the connection relationship between the support portion and the mattress portion in the technical solution of the present application will be further elaborated in multiple embodiments.

[0045] Embodiment 1:

[0046] Figure 4 It shows Figure 2 an enlarged view of the area A shown, Figure 5 and Figure 5a respectively show an exploded view of the vehicle-mounted inflatable mattress 10 of this embodiment and a perspective schematic diagram of the support portion. Specifically, the bottom wall 122 of the mattress portion 12 includes a first periphery 1220, and the first periphery 1220 includes a short side 1223 and a long side 1224. Optionally, a plurality of drawstrings 128 are all arranged along the width direction of the vehicle-mounted inflatable mattress 10, and the welding joints of the plurality of drawstrings 128 with the bottom wall 122 form a plurality of first weld seams 131. Preferably, a plurality of first weld seams 131 are all parallel to the short side 1223 of the bottom wall 122. Continuing to refer to Figure 4 and Figure 5 and Figure 5a, the support portion 14 is welded to the bottom wall 122 and forms a second weld 133, and the position of the second weld 133 is between two adjacent first welds 131 or between the short side 1223 and the first weld 131 adjacent to the short side 1223. Specifically, the support portion 14 includes a first wall 142 and a second wall 143, and the first wall 142 and the second wall 143 are connected to define a second inflation chamber (i.e., the inflation chamber of the support portion 14). The first wall 142 of the support portion 14 is welded to the bottom wall 122 of the mattress portion 12, and a second weld 133 is formed at the welding position, and the second weld 133 is between two adjacent first welds 131 or between the short side 1223 and the first weld 131 adjacent to the short side 1223. In practice, if the support portion 14 and the drawstring 128 are welded to the bottom wall 122 of the mattress portion 12 at the same position of the bottom wall 122 of the mattress portion 12, the same position will be subjected to a relatively large tensile force when the vehicle-mounted air mattress 10 is inflated and used. After the vehicle-mounted air mattress 10 is used for a long time, this position of the bottom wall 122 becomes more prone to tearing. In this embodiment, the welding position of the support portion 14 and the mattress portion 12 and the welding position of the drawstring 128 and the bottom wall 122 of the mattress portion 12 are staggered (i.e., the second weld 133 and the first weld 131 have no intersection), which avoids the above problem and further improves the durability of the vehicle-mounted air mattress 10.

[0047] Optionally, the first wall 142 of the support portion 14 may be formed of a polyvinyl chloride (PVC) film or a thermoplastic urethanes (TPU) film, and the bottom wall 122 of the mattress portion 12 may also be formed of a polyvinyl chloride (PVC) film or a thermoplastic urethanes (TPU) film.

[0048] Optionally, the second inflatable chamber of the support portion 14 and the first inflatable chamber 126 of the mattress portion 12 are independent chambers and are not connected to each other. Figure 4 , Figure 5 and Figure 5a Combined with Figure 2 Preferably, the second air-filled chamber of the support portion 14 is connected to the first air-filled chamber 126 of the mattress portion 12. Specifically, a vent hole 139 penetrating the first wall 142 of the support portion 14 and the bottom wall 122 of the mattress portion 12 may be provided to allow the second air-filled chamber to be connected to the first air-filled chamber 126. The number of the vent holes 139 is not limited and may be one, two or more. For example, Figure 4 , Figure 5 and Figure 5aAs shown, the vent hole 139 penetrates through the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12 and is arranged within the area surrounded by the second weld seam 133. When the second inflation chamber is in communication with the first inflation chamber 126, only one air plug needs to be arranged on the support part 14 or the mattress part 12, and there is no need to separately arrange air plugs on the support part 14 or the mattress part 12. In this way, the entire vehicle-mounted inflatable mattress 10 can be inflated for use or deflated for easy storage through only this one air plug, improving the efficiency of inflation and deflation.

[0049] Embodiment 2:

[0050] The vehicle-mounted inflatable mattress 10 of this embodiment is substantially the same as that of Embodiment 1, except that: the connection manner between the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12 is different. Specifically, Figure 6 shows Figure 2 an enlarged view of the area A shown, Figure 7 and Figure 7a respectively show an exploded view of the vehicle-mounted inflatable mattress 10 of this embodiment and a three-dimensional schematic diagram of the support part. Among them, the bottom wall 122 of the mattress part 12 includes a main body piece 1221 and a fitting piece 1222. Among them, the main body piece 1221 of the bottom wall 122 of the mattress part 12 includes a first inner layer 12211 and a first outer layer 12212; similarly, the first wall 142 of the support part 14 includes a main body piece 1421 and a fitting piece 1422. Among them, the main body piece 1421 of the first wall 142 of the support part 14 includes a second inner layer 14211 and a second outer layer 14212. Continuing to refer to Figure 6 、 Figure 7 and Figure 7a , the main body piece 1221 of the bottom wall 122 of the mattress part 12 includes an opening. As Figure 7 shown, the range surrounded by the opening contour line 12215 of the bottom wall 122 of the mattress part 12 is the opening of the bottom wall 122 of the mattress part 12; correspondingly, the main body piece 1421 of the first wall 142 of the support part 14 includes an opening, as Figure 7aAs shown, the range surrounded by the opening contour line 14215 of the first wall 142 of the support part 14 is the opening of the first wall 142 of the support part 14. The fitting piece 1222 of the bottom wall 122 of the mattress part 12 is welded to the first inner layer 12211 of the main piece 1221 of the bottom wall 122 of the mattress part 12 to cover the opening of the bottom wall 122 of the mattress part 12, and a third weld seam 12227 is formed at the welding position; similarly, the fitting piece 1422 of the first wall 142 of the support part 14 is welded to the second inner layer 14211 of the main piece 1421 of the first wall 142 of the support part 14 to cover the opening of the first wall 142 of the support part 14, and a fourth weld seam 14227 is formed at the welding position. Finally, the fitting piece 1222 of the bottom wall 122 of the mattress part 12 is welded to the fitting piece 1422 of the first wall 142 of the support part 14 to form a second weld seam 133, thereby realizing the connection between the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12. From Figure 6 and Figure 7 it can be seen that the third weld seam 12227, the opening contour line 12215 of the bottom wall 122 of the mattress part 12, and the second weld seam 133 are all between two adjacent first weld seams 131 or are all between the short side 1223 and the first weld seam 131 adjacent to the short side 1223. As described in the first embodiment, the first wall 142 of the support part 14 and the drawstring 128 are not welded at the same place on the bottom wall 122, which can prevent the bottom wall 122 from being more easily torn, thereby improving the durability of the vehicle-mounted inflatable mattress 10.

[0051] Optionally, the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12 can be made of composite materials. For example, the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12 can be made of fabric laminates or flocked materials. The "fabric laminate" refers to a double-layer material formed by laminating a fabric layer (such as a fabric or non-woven fabric) and a polymer sheet (such as a PVC film or a TPU film) to each other. The "flocked material" refers to a double-layer material formed by bonding a number of fluff hairs on a polymer sheet (such as a PVC film or a TPU film) to form a fluff layer, thus forming a composite of the fluff layer and the polymer sheet (such as a PVC film or a TPU film). For example, the first inner layer 12211 of the main sheet 1221 of the bottom wall 122 of the mattress part 12 can be made of a PVC film or a TPU film, and the first outer layer 12212 of the main sheet 1221 of the bottom wall 122 of the mattress part 12 can be made of a fabric layer or a fluff layer. The first inner layer 12211 and the first outer layer 12212 can be adhesively bonded to form a composite material, that is, a fabric laminate or a flocked material. The bonding sheet 1222 of the bottom wall 122 of the mattress part 12 can be made of a single-layer PVC film or TPU film; the second inner layer 14211 of the main sheet 1421 of the first wall 142 of the support part 14 can be made of a PVC film or a TPU film, and the second outer layer 14212 of the main sheet 1421 of the first wall 142 of the support part 14 can be made of a fabric layer or a fluff layer. The second inner layer 14211 and the second outer layer 14212 can be adhesively bonded to form a composite material, that is, a fabric laminate or a flocked material, and the bonding sheet 1422 of the first wall 142 of the support part 14 can be made of a single-layer PVC film or TPU film.

[0052] Similarly to the first embodiment, ventilation holes 139 can also be provided through the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12. Specifically, as Figure 6 、 Figure 7 and Figure 7a shown, the ventilation holes 139 are provided in the area surrounded by the second weld 133 and penetrate through the bonding sheet 1222 of the bottom wall 122 of the mattress part 12 and the bonding sheet 1422 of the first wall 142 of the support part 14, so that the first inflation chamber 126 of the mattress part 12 communicates with the second inflation chamber of the support part 14, thereby improving the inflation and deflation efficiency of the vehicle-mounted inflatable mattress 10.

[0053] Embodiment Three:

[0054] The vehicle-mounted inflatable mattress 10 of this embodiment is substantially the same as that of the first embodiment, except that: the connection manner between the first wall 142 of the support part 14 and the bottom wall 122 of the mattress part 12 is different. Specifically, Figure 8 shows Figure 2 an enlarged view of the area A shown in Figure 7 and Figure 9An exploded view of the in-vehicle inflatable mattress 10 of the present embodiment and a three-dimensional schematic diagram of the support portion are respectively shown. Among them, the bottom wall 122 of the mattress portion 12 includes a main sheet 1221 and a fitting sheet 1222. The main sheet 1221 of the bottom wall 122 of the mattress portion 12 includes a first inner layer 12211 and a first outer layer 12212. Continuing to refer to Figure 7 , Figure 8 and Figure 9 , the main sheet 1221 of the bottom wall 122 of the mattress portion 12 includes an opening, and the range surrounded by the opening contour line 12215 of the bottom wall 122 of the mattress portion 12 is the opening of the bottom wall 122 of the mattress portion 12. The fitting sheet 1222 of the bottom wall 122 of the mattress portion 12 is welded to the first inner layer 12211 of the main sheet 1221 of the bottom wall 122 of the mattress portion 12 to cover the opening of the bottom wall 122 of the mattress portion 12, and a third weld 12227 is formed at the welding position. The first wall 142 of the support portion 14 is welded to the fitting sheet 1222 of the bottom wall 122 of the mattress portion 12 to form a second weld 133, thereby realizing the connection between the first wall 122 of the support portion 14 and the bottom wall 122 of the mattress portion 12. As can be seen from Figure 7 and Figure 8 , the third weld 12227, the opening contour line 12215 of the bottom wall 122 of the mattress portion 12, and the second weld 133 are all between two adjacent first welds 131 or are all between the short side 1223 and the first weld 131 adjacent to the short side 1223. As described in Embodiment 1, the first wall 142 of the support portion 14 and the pull belt 128 are not welded at the same place on the bottom wall 122, which can prevent the bottom wall 122 from being more easily torn, thereby improving the durability of the in-vehicle inflatable mattress 10.

[0055] Optionally, the bottom wall 122 of the mattress portion 12 can be made of a composite material. For example, the first inner layer 12211 can be made of a PVC film or a TPU film, the first outer layer 12212 can be made of a cloth layer or a fluff layer, and the first inner layer 12211 and the first outer layer 12212 can be adhesively bonded to form a composite material, that is, a cloth surface bonding material or a flocking material. The fitting sheet 1222 of the bottom wall 122 of the mattress portion 12 can be made of a single-layer PVC film or a TPU film; the first wall 142 of the support portion 14 can be made of a single-layer PVC film or a TPU film.

[0056] Similar to Embodiment 1, a ventilation hole 139 can also be provided through the first wall 142 of the support portion 14 and the bottom wall 122 of the mattress portion 12. Specifically, as Figure 7 , Figure 8 and Figure 9As shown, the vent hole 139 is arranged within the area surrounded by the second weld seam 133 and penetrates through the bonding piece 1222 of the bottom wall 122 of the mattress part 12 and the first wall 142 of the support part 14, so that the first inflation chamber 126 of the mattress part 12 communicates with the second inflation chamber of the support part 14, thereby improving the inflation and deflation efficiency of the vehicle-mounted inflatable mattress 10.

[0057] Embodiment 4:

[0058] The vehicle-mounted inflatable mattress 10 of this embodiment is substantially the same as that of Embodiment 1, except that: a plurality of drawstrings 128 are all arranged along the length direction of the vehicle-mounted inflatable mattress 10. Specifically, as Figure 10 shown, multiple first weld seams 131 formed by welding the drawstrings 128 and the bottom wall 122 are all parallel to the long side 1224 of the bottom wall 122.

[0068] Embodiment Seven:

[0069] The in-vehicle inflatable mattress 10 of this embodiment is substantially the same as that of the first embodiment, except that: the support part 14 and the mattress part 12 are welded at the short side 1223 of the bottom wall 122 of the mattress part 12. Specifically, as Figure 15 shown, multiple drawstrings 128 are welded to the bottom wall 122 to form a plurality of first weld seams 131 that are all parallel to the short side 1223 of the bottom wall 122. The support part 14 is welded to the short side 1223 of the bottom wall 122, so that the support part 14 can rotate around the short side 1223 of the bottom wall 122. When the support part 14 rotates to the side of the bottom wall 122, the support part 14 plays a supporting role for the mattress part 12; when the support part 14 rotates to the side of the face wall 124, the support part 14 can be used as a backrest or a pillow, so that the in-vehicle inflatable mattress 10 can be used in different scenarios and better meet the needs of users.

[0070] Optionally, the support part 14 can also be welded to the long side 1224 of the bottom wall 122, so that the support part 14 can rotate around the long side 1224 of the bottom wall 122. As described above, the support part 14 can rotate to the side of the face wall 124 of the mattress part 12 to additionally serve as a backrest or a pillow.

Specifically, the first inflatable chamber 126 of the mattress part 12 is composed of a first region 127 and a second region 129. Among them, the first region 127 includes a sponge. The upper and lower surfaces of the sponge are respectively attached to the face wall 124 and the bottom wall 122 of the mattress part 12 to form the first region 127 of the first inflatable chamber 126 containing the sponge. The remaining part of the face wall 124 that is not attached to the sponge is connected to the remaining part of the bottom wall 122 that is not attached to the sponge to form the second region 129 of the first inflatable chamber 126 of the mattress part 12, and the second region 129 contains a plurality of drawstrings 128. The support part 14 is connected to the bottom wall 122 of the second region 129, and the connection method between the two can be any one of those described in the first to seventh embodiments above. Since the first region 127 contains a sponge, comparatively speaking, it makes the lying part of the vehicle-mounted inflatable mattress 10 flatter, further meeting the user's requirements for comfort.

[0073] Those skilled in the art can easily understand that the vehicle-mounted inflatable mattress 10 in all the above embodiments can be used not only in the vehicle but also in outdoor or indoor environments. For example, when camping or picnicking, the ground is often naturally formed and may have some uneven factors such as slopes. Also, the beach or grassland may be uneven due to terrain changes, human activities, etc. At this time, the vehicle-mounted inflatable mattress 10 including the support part 14 can match the uneven or inclined ground to keep the mattress part 12 in a horizontal position for users to lie on when camping or picnicking. Similarly, in some indoor environments such as temporary shelters or special-purpose rooms, there may also be uneven or inclined ground. The vehicle-mounted inflatable mattress 10 including the support part 14 can also be stably placed in these environments to keep the mattress part 12 in a horizontal position, thus ensuring the comfort of the user when lying down.
