Technical Field

[0001] The utility model belongs to the field of vehicle-mounted inflatable beds, and in particular relates to an air guide structure for connecting two inflatable products. Background Art

[0002] In recent years, more and more people choose to travel by car. Self-driving travel can satisfy people's pursuit and yearning for freedom. During the journey, you can stop and watch the beautiful scenery along the way, or even camp outdoors overnight. Because outdoor and in-car activities take a long time, in order to have a more comfortable travel experience, people's demand for car mattresses is also increasing.

[0003] Since the interior space of a car is uneven after the seats are folded down, in order to improve the comfort of sleeping in the car, the existing car mattress is configured as a structure consisting of a mattress body and an inflatable footrest, wherein the inflatable footrest fills the empty position to make the sleeping space in the car as wide and flat as possible.

[0004] At present, car mattresses are divided into pure air mattresses and self-inflating sponge mattresses. Existing pure air mattresses can connect the inflatable footrests into one body through the hot pressing process, which can reduce the operation steps of inflating and deflating the footrests. Users can use the pure air mattress more conveniently and quickly, but the footrests have poor support, which reduces the comfort of using the pure air mattress. The self-inflating sponge mattress has better comfort, but due to the difference in structure between the inflatable sponge bed and the inflatable footrest, the use of hot pressing technology to achieve integrated connection and inflation will increase more labor costs, and the operation during inflation and deflation is troublesome. At the same time, the product appearance changes too much and is not beautiful, so the overall promotion is not high.

[0005] In view of the problem that it is difficult to strike a balance between comfort of use and convenience of inflation and deflation in the vehicle-mounted inflatable mattress in the prior art, a more reasonable solution needs to be proposed to solve the current technical problem.

[0008] In a possible design, the first connecting member is formed with a first cylinder body that matches the second air hole, and the first cylinder body is sealedly inserted into the second air hole;

[0009] Alternatively, the second connecting member is formed with a second cylinder body matched with the first air hole, and the second cylinder body is sealingly inserted in the first air hole.

[0010] In a possible design, the first cylinder of the first connecting member protrudes from the outer wall of the inflatable product; the second connecting member is buried in the inflatable product; when the first cylinder of the first connecting member is inserted into the second air hole, the outer wall of one inflatable product fits against the outer wall of the other inflatable product.

[0011] In a possible design, the first connecting member includes a first base and a first cylinder; the first base is connected to the inflatable product by heat pressing; and the first cylinder protrudes from the outer wall surface of the inflatable product.

[0012] In a possible design, the first base and the first cylinder are both made of plastic material, and the two are integrally formed.

[0013] In a possible design, the end of the first cylinder is provided with a rounded corner or a beveled corner to form a smooth guiding surface.

[0015] In a possible design, the second base is provided with an inclined surface or a curved surface.

[0016] In a possible design, the second base and the second cylinder are both made of plastic material, and are integrally formed.

[0017] In a possible design, the air guide structure also includes a third connecting member, both ends of which are sealed and inserted into the first air hole and the second air hole respectively, and a blocking part is provided on the third connecting member to block the connection between the first air hole and the second air hole.

[0019] In a possible design, a plurality of spaced-apart limiting rings are provided at the outer circumference of the first cylinder so as to be sealably inserted into the second cylinder.

[0020] Through the above technical solution, the first connector and the second connector can be hot-pressed on the inflatable products to be connected respectively.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation on the present invention. The specific structural and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0029] According to the specific implementation of the utility model, an air guide structure for connecting two inflatable products is provided, which can respectively connect the two inflatable products, a sponge air bed and an inflatable footrest, so as to realize the circulation of the air flow channel to achieve integrated inflation; it can also connect two pure inflatable products to achieve the effect of integrated inflation, which can effectively solve the problems of cumbersome use, difficult production and high labor costs. Among them, Figures 1 to 3 One specific embodiment is shown.

[0030] See also Figures 1 to 3 As shown, the air guide structure for connecting two inflatable products includes a first connecting member 1 and a second connecting member 2; the first connecting member 1 is arranged on one of the inflatable products, and the first connecting member 1 is provided with a first air hole 101 connected to the inflatable product; the second connecting member 2 is arranged on the other inflatable product, and the second connecting member 2 is provided with a second air hole 201 for fluid to pass through; the first connecting member 1 is removably sealed and connected to the second connecting member 2, so that the first air hole 101 and the second air hole 201 form an air flow channel between the two inflatable products.

[0031] Take the application of the connection structure to a sponge air mattress 3 (inflatable product) and an inflatable footrest 4 (inflatable product) as an example. Figure 3 As shown, two footrests 4 are arranged below the sponge air bed 3, and each inflatable footrest 4 is connected to the first connecting member 1 of the air bed using two second connecting members 2. Figure 2 As shown, the connection is made by hot pressing, a hole is opened at the bottom of the airbed, the size of the hole is the same as the outer diameter of the cylindrical structure of the first connecting member 1, and the first connecting member 1 is inserted into the hole and then hot pressed. Figure 1As shown, the first connector 1 and the second connector 2 are both cylindrical structures with inner holes. The first connector 1 and the second connector 2 are respectively hot-pressed on the inflatable products to be connected. In this way, when the first connector 1 and the second connector 2 are sealed and connected, the gas between the two inflatable products can flow between the air flow channels, thereby allowing the two products to be inflated as one, which is more convenient and quick to use. In this way, the inflatable products have supporting and fitting parts to each other, which can provide stable and reliable support for the inflatable products located above, can be applied to uneven placement base surfaces in the car, and can improve the comfort of the inflatable mattress. At the same time, based on this connection structure, the mattress and the footrest 4 can be inflated as one, which improves the convenience of operation. In this way, the problem of the difficulty in balancing the comfort of use and the convenience of inflation and deflation of the vehicle-mounted inflatable mattress in the prior art is solved.

[0032] In one embodiment provided by the present disclosure, the first connecting member 1 is formed with a first cylinder 11 that matches the second air hole 201, and the first cylinder 11 is sealed and inserted into the second air hole 201. That is to say, in this way, the first connecting member 1 can be set on the sponge air bed 3, and the second connecting member 2 can be set on the pedal 4. When in use, the second connecting member 2 on the pedal 4 is sealed and sleeved on the outer periphery of the first cylinder 11, so as to achieve a sealed connection between the first connecting member 1 and the second connecting member 2. Such a design structure can facilitate the second connecting member 2 on the pedal 4 to quickly align with the first cylinder 11 on the first connecting member 1, so as to achieve rapid assembly. At the same time, it can also avoid interference with the sponge material on the sponge air bed 3.

[0033] In another embodiment, the second connecting member 2 is formed with a second cylinder 21 that matches the first air hole 101, and the second cylinder 21 can be inserted into the first air hole 101 in a sealing manner. Specifically, the first connecting member 1 on the sponge air bed 3 is sealedly sleeved on the outer periphery of the second cylinder 21, thereby achieving a sealed connection between the first connecting member 1 and the second connecting member 2. In this way, quick assembly can also be achieved based on the matching structure of the second cylinder 21 and the first air hole 101.

[0034] It should be noted that, no matter the first cylinder is inserted into the second air hole, or the second cylinder is inserted into the first air hole, an interference fit should be adopted to achieve a sealed connection between the first connector and the second connector. In order to ensure air tightness, a sealing ring can be sleeved on the outer periphery of the first cylinder, so as to seal the gap between the first cylinder and the second air hole based on the deformation of the sealing ring, thereby further ensuring air tightness.

[0035] Specifically, the first cylinder 11 of the first connecting member 1 protrudes from the outer wall of the inflatable product; the second connecting member 2 is embedded in the inflatable product; when the first cylinder 11 of the first connecting member 1 is inserted into the second air hole 201, the outer wall of one inflatable product fits against the outer wall of the other inflatable product. This helps to make the two inflatable products fit smoothly, so that the mattress can maintain a flat state after inflation, avoiding uneven shapes. In addition, the cooperation between the first cylinder and the second air hole can also play a supporting role similar to that of an air column, which helps to ensure the supporting effect of the sponge air bed.

[0036] In the present disclosure, the first connector 1 includes a first base 12 and a first barrel 11; the first base 12 is connected to the inflatable product by heat pressing; the first barrel 11 protrudes from the outer wall of the inflatable product. Based on the heat pressing connection method, the first base 12 can be sealed and connected to the inflatable product, and it is also convenient for the first barrel 11 to be inserted into the second inner hole of the second connector 2 on another inflatable product.

[0037] In order to better adapt to the flexible inflatable products, the first base 12 and the first cylinder 11 are both made of plastic materials, which is convenient for installation. The first base 12 and the first cylinder 11 are integrally formed, which is beneficial to ensure the connection strength between the two, while reducing the shape and position errors between the two, and is easy to manufacture.

[0038] In an embodiment provided in the present disclosure, the end of the first cylinder 11 is provided with a rounded corner or an oblique angle to form a smooth guiding surface, thereby playing a certain guiding role and enabling it to be smoothly inserted into the second air hole 201 .

[0039] In an embodiment provided by the present disclosure, the second connector 2 includes a second base 22 and a second cylinder 21, the second base 22 is connected to the inflatable product by heat pressing, and the second cylinder 21 is embedded in the inflatable product. Based on the heat pressing connection method, the second connector 2 can be sealed and connected to the inflatable product. At the same time, the second cylinder 21 is embedded in the inflatable product, which can reduce the space occupied, so that the two inflatable products can be reliably connected to achieve integrated inflation.

[0040] In the present disclosure, the second base 22 is provided with an inclined surface or an arc surface, so as to play a certain guiding role, so that the first cylinder 11 of the first connecting member 1 can be smoothly inserted into the second air hole 201.

[0041] In order to better adapt to the flexible inflatable products, the second base 22 and the second cylinder 21 are both made of plastic materials, which is convenient for installation. The second base 22 and the second cylinder 21 are integrally formed, which is beneficial to ensure the connection strength between the two, while reducing the shape and position error between the two, and is convenient for production.

[0042] As a preferred embodiment, see Figure 5 As shown, the air guide structure also includes a third connecting member 5, the two ends of which are respectively sealed and inserted into the first air hole 101 and the second air hole 201, and a blocking portion is provided on the third connecting member 5 to block the communication between the first air hole 101 and the second air hole 201. In other words, the third connecting member 5 is a solid structure and is not ventilated. Therefore, after the two ends of the third connecting member 5 are respectively connected to the first hole and the second air hole 201, they can be similar to plugs or stoppers to respectively close the inflatable foot pedal 4 and the sponge bed, so as to facilitate the later testing of the air tightness of the inflatable foot pedal 4 and the sponge bed (water soaking test). In addition, it has a simple structure, is easy to operate, and has good practicality.

[0043] Specifically, the third connecting member 5 includes an upper shaft section for inserting into the first air hole 101 and a lower shaft section for inserting into the second air hole 201, the upper shaft section is integrally connected to the lower shaft section, and the blocking part is arranged on the upper shaft section or the lower shaft section, thereby blocking the fluid flow between the two products. Among them, the thickness and setting position of the group partition part can be flexibly set by those skilled in the art according to actual needs.

[0044] Furthermore, both the upper shaft section and the lower shaft section are provided with annular wing plates, and the two wing plates are connected by stiffening ribs. There are multiple stiffening ribs, which are evenly spaced along the circumferential direction. In this way, the wing plates can limit the depth of the insertion hole, and at the same time, they can also provide a certain support effect on the product. The setting of the stiffening ribs is beneficial to improving the bending strength of the third connecting member 5 and ensuring its support effect.

[0045] In the present disclosure, the upper shaft section, the lower shaft section, the wing plate and the stiffening ribs are integrally cast and molded using hard plastic, which is beneficial to ensure the connection strength between them and reduce shape and position errors.

[0046] In an embodiment provided by the present disclosure, the first connecting member 1 has a first cylinder 11, and the second connecting member 2 has a second cylinder 21; the first cylinder 11 and the second cylinder 21 have the same orientation, and the first cylinder 11 can be sealed and inserted into the second cylinder 21, so that the gas in the inflatable product is introduced from the first cylinder 11 to another inflatable product. And the cooperation of the first cylinder and the second cylinder can play a supporting role to a certain extent, so that the inflatable product can stably bear gravity.

[0047] See also Figure 4As shown, in a preferred embodiment shown in the present disclosure, the outer circumference of the first cylinder is provided with multiple layers of spaced-apart limiting rings 13 so as to be inserted into the second cylinder in a sealed manner. During operation, the first cylinder can be pressed into the second cylinder. Based on the setting of the limiting ring 13, not only can the air tightness be ensured, but also the connection strength between the first cylinder and the second cylinder can be strengthened, so that the first cylinder is not easy to fall out during inflation and use.

[0048] Finally, it should be noted that the utility model is not limited to the above optional implementations, and anyone can derive other various forms of products under the inspiration of the utility model. The above specific implementations should not be understood as limiting the scope of protection of the utility model. The scope of protection of the utility model shall be based on the definition in the claims, and the description can be used to interpret the claims.
