[0042] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0043] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0044] like Figure 1 , Figure 2 and Figure 4As shown, the present invention provides a retractable air mattress structure, including an air mattress 1, a driving unit 2 and an inflation unit 3. The driving unit 2 includes a driving member 22 and a rotating shaft 21, the driving member 22 drives the rotating shaft 21 to rotate, the air mattress 1 has a first end 12 and a second end 13 opposite to each other, the first end 12 of the air mattress 1 is connected to the rotating shaft 21 and can rotate together with the rotating shaft 21, when the driving member 22 drives the rotating shaft 21 to rotate, the air mattress 1 is fixedly connected to the rotating shaft 21 due to the first end 12, and during the rotation of the rotating shaft 21, the air mattress 1 is rolled up on the rotating shaft 21, when the air mattress 1 needs to be unrolled, the driving member 22 drives the rotating shaft 21 to rotate in the opposite direction, so that the air mattress 1 is unrolled. The inflation unit 3 includes an inflation member 32 and an inflation tube 31, and the inflation tube 31 connects the inflation member 32 and the air mattress 1.

[0045] In the retractable air mattress structure provided by the present invention, the driving member 22 drives the rotating shaft 21 to rotate, so as to retract and unwind the air mattress 1. Since the material of the air mattress 1 is relatively soft, the air mattress 1 can be wound on the rotating shaft 21. When the air mattress 1 needs to be unrolled and spread out, the driving member 22 drives the rotating shaft 21 to rotate in one direction, so that the air mattress 1 is unrolled and spread out. When the air mattress 1 needs to be rolled up and stored, the driving member 22 drives the rotating shaft 21 to rotate in the opposite direction, so that the air mattress 1 is wound on the rotating shaft 21. The driving member 22 can be a motor, and the output end of the motor is fixedly connected to the rotating shaft 21. The air mattress 1 is retracted and unrolled by the forward and reverse rotation of the motor. After the air mattress 1 is unrolled and spread out, the inflatable member 32 inflates the air mattress 1 through the inflation tube 31, so that the user can lie down and rest. After the user has rested, the air mattress 1 is deflated. During the process of the air mattress 1 being rolled up on the rotating shaft 21, the air mattress 1 is squeezed and part of the gas in the air mattress 1 can be discharged.

[0046] Preferably, the inflatable member 32 can also draw air from the air mattress 1, so that when the air mattress 1 needs to be stored after resting, the air mattress 1 can be deflated through the inflatable member 32, and the air mattress 1 can be quickly stored. The inflatable member 32 can be an air pump that can inflate and deflat, which can conveniently complete the inflation and deflation of the air mattress 1, making it easy to spread out and store the air mattress 1.

[0047] The telescopic air mattress structure provided in this embodiment also includes a control unit 4. The driving member 22 and the inflatable member 32 are both connected to the control unit 4 through a wire 5. The control unit 4 can be electrically connected to an external device through a harness connector 6. The control unit 4 controls the working parameters of the driving member 22 and the inflatable member 32. The working parameters of the driving member 22 can be the speed at which the driving member 22 drives the rotating shaft 21 to rotate (i.e., the speed at which the air mattress 1 is rolled up and unrolled), the number of turns at which the driving member 22 drives the rotating shaft 21 to rotate (i.e., the distance the air mattress 1 is spread out), etc. The working parameters of the inflatable member 32 can be the inflation speed, the size of the inflation amount, etc., and can also be the start time of the driving member 22 and the inflatable member 32. For example, the driving member 22 can be started first, and after the air mattress 1 is fully spread out, the inflatable member 32 is started to inflate the air mattress 1, or the inflatable member 32 is started after the driving member 22 is started but before the air mattress 1 is fully spread out, so that the air mattress 1 is inflated during the spreading process, which can improve the inflation efficiency of the air mattress 1.

[0048] Furthermore, the inflation tube 31 is installed on the air mattress 1 along the side of the air mattress 1, and the inflation tube 31 is a hose. That is, the shape formed by the inflation tube 31 is consistent with the shape of the air mattress 1. Since the material of the air mattress 1 is relatively soft, if the air mattress 1 is not inflated during the spreading process, the air mattress 1 is easy to pile up due to its soft material, and the air mattress 1 needs to be manually adjusted during the subsequent inflation process. The inflation tube 31 is installed on the air mattress 1 along the side of the air mattress 1, so that the air mattress 1 can roughly maintain the spread shape during the unwinding process of the air mattress 1, which is conducive to the subsequent inflation.

[0049] like Figure 3 As shown, a circular rotating groove is provided on the inflatable member 32, and a rotating member 33 with a circular outer wall is installed in the rotating groove. A vent hole is provided on the rotating member 33, and one end of the inflation tube 31 is fixedly connected to the vent hole. In this way, when the inflation tube 31 follows the winding and unwinding of the air mattress 1, the rotation of the rotating member 33 can prevent the inflation tube 31 from getting tangled.

[0050] Preferably, the hardness of the material of the inflation tube 31 is greater than that of the air mattress 1, so that the inflation tube 31 can better keep the air mattress 1 roughly in a spread-out shape, and the cross-section of the inflation tube 31 is elliptical, so that during the rolling process of the air mattress 1, the inflation tube 31 is easier to stack layer by layer. The stacking of the inflation tubes 31 can guide the rolling of the air mattress 1 and prevent the air mattress 1 from deviating during the rolling process, thereby preventing the rolling from being messy.

[0051] At the same time, the second end 13 of the air mattress 1 is provided with a plurality of inflation holes 11, and the inflation tube 31 inflates the air mattress 1 through the inflation holes 11. Since the second end 13 of the air mattress 1 is the end of the air mattress 1 away from the inflation member 32, the second end 13 of the air mattress 1 is the first to be away from the inflation member 32 during the spreading process of the air mattress 1, and inflation can be started when the air mattress 1 starts to be away from the inflation member 32, which can improve the inflation efficiency. In addition, the second end 13 of the air mattress 1 is first filled with gas, which can slightly increase the weight of the second end 13 of the air mattress 1, so that the second end 13 of the air mattress 1 sinks downward, which is convenient for the air mattress 1 to be spread out neatly.

[0052] In summary, the telescopic air mattress structure provided in this embodiment can conveniently roll up and unroll the air mattress 1 without manual intervention. It can also inflate during the unrolling process and evacuate during the rewinding process, thereby improving the efficiency of spreading out and storing the air mattress 1. At the same time, the air mattress 1 can be guided by the inflation hose 31, so that the air mattress 1 can be neatly spread out and stored.

[0053] like Figures 5 to 8 As shown, this embodiment also provides a car trunk structure, including a bottom plate 7, a trunk threshold 8, and the telescopic air bed structure as described above, wherein the bottom plate 7 is a plate in the car trunk for supporting articles, the bottom plate 7 and the side surround of the trunk and the trunk door enclose a storage space for storing articles, and the trunk threshold 8 is a threshold that cooperates with the trunk door to close the rear of the car. The telescopic air bed structure is installed as a whole below the bottom plate 7, and a gap 9 is formed between the bottom plate 7 and the trunk threshold 8. When the air bed 1 is rolled up on the rotating shaft 21, the second end 13 of the air bed 1 is located at the gap 9, and when the air bed 1 is unrolled under the drive of the driving unit 2, the second end 13 of the air bed 1 passes through the gap 9 and the air bed 1 is unrolled toward the bottom plate 7.

[0054] In the car trunk structure provided in this embodiment, when the air mattress 1 is not needed, the air mattress 1 is rolled up on the rotating shaft 21 in the manner described above, and the rotating shaft 21 is located below the bottom plate 7. At this time, the car trunk is no different from the traditional trunk. When the air mattress 1 is needed, the driving member 22 drives the rotating shaft 21 to rotate, and the rotating shaft 21 unwinds the air mattress 1 during the rotation process. The second end 13 of the air mattress 1 extends through the gap 9 between the bottom plate 7 and the trunk threshold 8, so that the air mattress 1 is spread out on the bottom plate 7. After the air mattress 1 is inflated, it can be used for people to rest in the trunk. When the air mattress 1 needs to be stored after resting, the driving member 22 drives the rotating shaft 21 to reverse, and the air mattress 1 is rolled up on the rotating shaft 21 driven by the rotating shaft 21. Finally, the air mattress 1 is rolled up as a whole below the bottom plate 7, and does not occupy the space of the trunk.

[0055] Furthermore, the automobile trunk structure provided in this embodiment also includes a guide plate 16, which is rolled in a cylindrical shape and has an opening along the length direction of the cylindrical shape. The guide plate 16 is installed on the trunk threshold 8 and is located below the floor 7. The opening of the guide plate 16 faces the gap 9 between the floor 7 and the trunk threshold 8. When the air mattress 1 is rolled up, the rolling action of the air mattress 1 is to take the first end 12 of the air mattress 1 as the center of the circle, and the air mattress 1 is rolled around the center of the circle. The air mattress 1 is guided by the guide plate 16 during the rolling process, so that the air mattress 1 is stored in the guide plate 16 in an orderly manner.

[0056] The automobile trunk structure provided in this embodiment also includes a cover plate 10, one end of which is rotatably connected to the trunk threshold 8. The cover plate 10 is rotatably covered at the interval 9 and the size of the cover plate 10 is not less than the size of the interval 9. In this way, the interval 9 between the bottom plate 7 and the trunk threshold 8 can be covered by the cover plate 10 to prevent smaller items from falling from the interval 9 to the bottom plate 7. When the air mattress 1 is unrolled, the second end 13 of the air mattress 1 pushes open the cover plate 10, and the air mattress 1 is unrolled normally. After the air mattress 1 is rolled up, the cover plate 10 is covered at the interval 9 between the bottom plate 7 and the trunk threshold 8 by hand.

[0057] Furthermore, the cover plate 10 provided in this embodiment also includes an elastic reset member, which is connected to the cover plate 10 and the trunk door sill 8. In the initial position, the cover plate 10 is located at the gap 9. After the cover plate 10 rotates, it is elastically reset to the initial position by the elastic reset member. In this way, the cover plate 10 can be always closed at the gap 9 between the bottom plate 7 and the trunk door sill 8, preventing small items from falling from the gap 9.

[0058] Specifically, Fig. 9 and Fig.10 As shown, a support portion perpendicular to the trunk threshold 8 extends from the side of the trunk threshold 8 facing the interior of the car, and a plurality of mounting seats are provided on the support portion, and grooves are provided on the mounting seats upwardly, and a rotating shaft 101 is provided on the cover plate 10, and the rotating shaft 101 is rotatably mounted in the grooves of the mounting seats, so that the cover plate 10 can rotate on the trunk threshold 8. A torsion spring is sleeved on the rotating shaft 101 of the cover plate 10, one end of the torsion spring abuts on the cover plate 10, and the other end of the torsion spring abuts on the support portion of the trunk threshold 8, so that the cover plate 10 can be reset by the torsion spring after the cover plate 10 rotates, so that the cover plate 10 is normally closed at the interval 9 between the bottom plate 7 and the trunk threshold 8.

[0059] In summary, the automobile trunk structure provided in the present embodiment can install the air bed 1 without occupying the space in the trunk. When the air bed 1 is needed, the air bed 1 can be quickly spread out. When the air bed 1 is not needed, the air bed 1 can be quickly stored. The airtightness of the trunk is ensured by the cover plate 10, and the original function of the trunk will not be affected by the addition of the air bed 1.

[0060] like Fig.11 and Fig.12 As shown, this embodiment also provides a car, including a front seat 15, a rear seat 14 and the car trunk structure as described above, and the rear seat 14 includes a seat 142 and a backrest 141. In this embodiment, the backrest 141 of the rear seat 14 can be folded in a direction away from or close to the trunk threshold 8. In this embodiment, the backrest 141 of the rear seat 14 can be folded in a direction away from the trunk threshold 8. When the air mattress 1 is unrolled, it can be unrolled onto the backrest 141 of the rear seat 14. In this way, the space inside the car can be fully utilized, so that the air mattress 1 can be spread out in a larger area, and people's leisure and entertainment experience can be improved.

[0061] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
