Description

Technical Field

[0001] This utility model relates to the field of portable inflatable mattress technology, specifically a vehicle-mounted portable foldable inflatable mattress. Background Technology

[0002] In recent years, with the improvement of people's living standards, activities such as self-driving tours and outdoor camping have become increasingly popular. According to data from the China Tourism Academy, in 2024, the proportion of domestic self-driving tourists exceeded 60%. During long-distance self-driving tours or outdoor camping, people have a strong demand for comfortable resting spaces. Traditional car seats are insufficient to meet the needs of prolonged sleep, leading to a surge in demand for car inflatable mattresses. At the same time, urban commuters, truck drivers, and other groups also need temporary rest in their vehicles, further expanding the market demand for portable, foldable car inflatable mattresses.

[0003] However, existing portable foldable air mattresses for vehicles still have some problems when used:

[0004] First, existing air mattresses are inefficient at deflation, making it difficult to completely expel air. As a result, they are still quite bulky after being folded, making them inconvenient to store. In addition, the sealing cap at the vent pipe is prone to loosening, causing the air mattress to deflate during use and affecting its performance.

[0005] Secondly, existing inflatable mattresses are poorly adapted to the interior space of a car, lacking an elastic design at the edges. After inflation, they cannot fit tightly to the contours of the car interior, creating large gaps that reduce both support stability and comfort during use. Utility Model Content

[0006] In order to solve the problems of low deflation efficiency and poor adaptability of existing air mattresses to vehicle interior space, the purpose of this utility model is to provide a portable foldable air mattress for vehicles.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a portable foldable inflatable mattress for vehicles, comprising a mattress body, extension components on both sides of the mattress body, multiple one-way air inlet valves connected to one side of the mattress body, and multiple exhaust components on the other side of the mattress body, each exhaust component including an exhaust pipe connected to one side of the mattress body, a sealing cover movably snapped onto one side of the exhaust pipe, a first positioning plate symmetrically fixedly connected to the outer surface of the sealing cover, a second positioning plate symmetrically fixedly connected to the outer surface of the exhaust pipe, and corresponding first and second positioning plates being threadedly connected to positioning bolts.

[0008] Preferably, the extension component includes symmetrically distributed air bags, which are fixedly installed on both sides of the mattress body. One side of each air bag is connected to a plurality of bidirectional air valves, and the outer surface of each bidirectional air valve is threaded with a first dust cover.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application uses an exhaust assembly to change the exhaust port of the exhaust pipe to a large-diameter structure, which can greatly increase the exhaust speed when deflating the air mattress, ensuring that the air is completely expelled, which facilitates efficient folding and storage. At the same time, an anti-loosening structure is set at the sealing cover to prevent the air mattress from leaking during use, effectively improving the performance of the air mattress.

[0011] 2. This application uses an extension component to set inflatable air bags on both sides of the air mattress. By adjusting the air pressure of the air bags, it can precisely fit the curves of the vehicle body, so that the mattress can fit tightly to the contours of the vehicle after inflation, avoiding gaps. This design not only improves the stability of the mattress support, but also improves the comfort of the mattress when used. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-6 As shown, this utility model provides a portable foldable inflatable mattress for vehicles, including a mattress body 1. A rubber anti-slip pad 6 is fixedly connected to the lower surface of the mattress body 1. The rubber anti-slip pad 6 increases the friction with the floor mat or seat surface of the vehicle, effectively preventing the mattress body 1 from sliding during use due to passenger turning over or vehicle bumps. Both sides of the mattress body 1 are provided with extension components 3. The extension components 3 allow the mattress to better adapt to the interior space of different vehicle models. By flexibly adjusting the extension components 3, the gap between the mattress and the edge of the vehicle interior can be filled, enhancing the fit between the mattress and the vehicle body, thereby improving the support effect of the mattress and the comfort of the user.

[0022] One side of the mattress body 1 is connected to multiple one-way air intake valves 5. The design of multiple one-way air intake valves 5 enables simultaneous air intake through multiple channels, accelerating the inflation speed of the mattress body 1. The one-way conduction characteristic of the one-way air intake valves 5 can prevent gas backflow during inflation. A second dust cover 4 is threaded onto the outer surface of the one-way air intake valve 5, which can effectively prevent dust and debris from entering the valve. The other side of the mattress body 1 is provided with multiple sets of exhaust components 2. The presence of multiple sets of exhaust components 2 can significantly improve the deflation efficiency of the mattress body 1. When the mattress needs to be stored, multiple sets of exhaust components 2 work simultaneously to quickly expel the air inside the mattress, reducing deflation time and making the mattress easier to fold, carry and store.

[0023] The exhaust assembly 2 includes an exhaust pipe 21, which is connected to one side of the mattress body 1. The exhaust pipe 21 provides a direct channel for the exhaust of gas inside the mattress, ensuring that the gas can flow out smoothly. It is the basic structure for achieving rapid exhaust. A sealing cover 25 is movably engaged on one side of the exhaust pipe 21. The inner shape of the sealing cover 25 matches the inner shape of the exhaust pipe 21. The sealing cover 25 and the exhaust pipe 21 are movably engaged and their inner shapes match, which can achieve a tight fit. When the air mattress is in use, the exhaust pipe 21 is effectively sealed to prevent gas leakage and ensure the stable inflation state of the mattress.

[0024] The outer surface of the sealing cover 25 is symmetrically fixedly connected to a first positioning plate 24, and the outer surface of the exhaust pipe 21 is symmetrically fixedly connected to a second positioning plate 22. Correspondingly, the first positioning plate 24 and the second positioning plate 22 are threadedly connected to a positioning bolt 26. The combination of the first positioning plate 24, the second positioning plate 22 and the positioning bolt 26 forms an anti-loosening structure. The positioning bolt 26 firmly connects the first positioning plate 24 and the second positioning plate 22, preventing the sealing cover 25 from loosening or falling off due to vibration, squeezing or other reasons during use, and further enhancing the sealing reliability of the exhaust pipe 21. The first positioning plate 24 and the second positioning plate 22 are both magnetic plates, and the first positioning plate 24 and the second positioning plate 22 are magnetically connected. The magnetic design of the first positioning plate 24 and the second positioning plate 22 allows for initial alignment by magnetic attraction when installing the sealing cover 25, making it convenient for users to quickly find the positioning position and simplifying the installation steps.

[0025] The second positioning plate 22 has a threaded hole 23 on one side for use with the positioning bolt 26. The positioning bolt 26 is threadedly connected to the threaded hole 23. The threaded connection between the threaded hole 23 and the positioning bolt 26 provides a firm fixing method for the sealing cover 25, making the seal between the sealing cover 25 and the exhaust pipe 21 more stable, effectively avoiding air leakage caused by the loosening of the sealing cover 25, and improving the reliability of the air mattress.

[0026] The extension component 3 includes symmetrically distributed air bags 31, which are fixedly installed on both sides of the mattress body 1. By inflating, the air bags 31 can fill the gap between the mattress and the edge of the car interior, allowing the mattress to better conform to the irregular contours of the car interior. At the same time, the air bags 31 can also provide additional support for the edge of the mattress, improving the overall support stability and comfort.

[0027] The air bag 31 is connected to a plurality of bidirectional air valves 32 on one side. The air bag 31 is a compartmentalized air bag. The multiple bidirectional air valves 32 can realize the rapid inflation and precise deflation of the air bag 31. Users can flexibly adjust the air pressure of each compartment air bag according to the shape of the vehicle interior space and personal needs, so that the air bag 31 can better fit the curves of the vehicle body. The compartmentalized air bag design further improves the flexibility and accuracy of adjustment. Different compartments can be inflated or deflated independently. The outer surface of the bidirectional air valve 32 is threaded with a first dust cover 33. The first dust cover 33 is threaded on the outer surface of the bidirectional air valve 32, which can prevent dust and debris from entering the interior of the bidirectional air valve 32 and avoid the air valve's sealing performance and normal operation due to impurities.

[0028] Working principle: First, unfold the folded air mattress and place it in a suitable position in the vehicle. Then, unscrew the second dust cover 4 from the outer surface of the one-way air valve 5 and connect it to the vehicle air pump or manual inflation device. Gas is simultaneously injected into the mattress body 1 through multiple one-way air valves 5. The one-way conduction characteristic of the one-way air valve 5 can effectively prevent gas backflow and ensure inflation efficiency.

[0029] When the mattress body 1 is inflated to half full, if it is necessary to adjust the fit between the mattress and the vehicle interior, it can be done through the extension component 3. Unscrew the first dust cover 33 outside the two-way air valve 32, and use the two-way air valve 32 to inflate the air bag 31. Since the air bag 31 adopts a compartmentalized design, the air pressure of each compartment can be adjusted separately, so that it can better fit the curves of the vehicle body, fill the gap between the mattress and the edge of the vehicle interior, and significantly enhance the adaptability of the mattress to the vehicle interior.

[0030] After the mattress is inflated, it is necessary to ensure the airtightness of the exhaust assembly 2. The sealing cover 25 on one side of the exhaust pipe 21 is fixed by the first positioning plate 24, the second positioning plate 22 and the positioning bolt 26. The inner cavity of the sealing cover 25 matches the inner cavity shape of the exhaust pipe 21, which can form a tight seal, effectively prevent gas leakage in the mattress body 1 and maintain a stable inflation state.

[0031] During use, the rubber anti-slip pad 6 on the lower surface of the mattress body 1 is in close contact with the floor mat or seat surface of the vehicle. The high friction of the rubber prevents the mattress from sliding due to passenger movement or vehicle bumps. After use, the deflation and storage operation begins. First, unscrew the positioning bolt 26 to disconnect the first positioning plate 24 from the second positioning plate 22. Then, remove the sealing cover 25. At this point, the exhaust pipe 21 in the multiple exhaust assemblies 2 connects to the mattress body 1, forming a gas exhaust channel that can quickly expel air from inside the mattress body 1.

[0032] At the same time, the gas inside the air bag 31 is released through the two-way air valve 32. After the gas inside the mattress body 1 and the air bag 31 is completely expelled, it is folded. Since the gas is completely expelled, the volume after folding is greatly reduced, making it easy to carry and store.

[0033] Finally, screw the first dust cover 33 back onto the two-way air valve 32 and the second dust cover 4 back onto the one-way air inlet valve 5 to prevent dust and debris from entering the air valve, protect the air valve performance, and prepare for the next use.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
