Description

Technical Field

[0001] This application relates to an airbag structure, and more particularly to an airbag arch lock structure, belonging to the field of smart home technology. Background Technology

[0002] For a long time, blankets have had a significant impact on people's sleep quality. Sometimes the inside of the blanket can be quite hot at night, causing people to sweat easily. During sleep, people often unconsciously lift the blanket, which can easily lead to catching a cold, especially infants and young children. Current blankets have a simple structure and lack the function of automatically sensing the internal temperature and adjusting the blanket's position. When the inside of the blanket is too hot, slightly arching it open helps dissipate heat. Once the internal temperature has lowered appropriately, putting the blanket back down promotes sleep, avoids sweating and lifting the blanket, and prevents catching a cold in the middle of the night.

[0003] However, there is a lack of driving mechanisms to lift and flatten thin bedding and other coverings, which rely on complex mechanical structures, such as multi-link mechanisms or gear transmission mechanisms. These structures typically contain numerous parts with cumbersome interrelationships. Traditional complex mechanical driving mechanisms reduce the comfort of bedding and make it difficult to move and operate flexibly in actual use, failing to meet users' needs for comfort and ease of use. This application aims to solve the above problems by precisely adjusting the air pressure of the airbag to solve the problem of lifting and flattening thin items such as bedding. It has the advantages of simple structure, light weight, and good adaptability, effectively overcoming the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this application is to address the shortcomings of existing drive devices for raising and flattening thin blankets and other coverings. These devices are complex in structure, contain numerous parts, and have complicated interrelationships, making them difficult to move and operate flexibly in actual use. Consequently, they fail to meet users' needs for comfort and ease of use, resulting in poor comfort. This application provides a reasonably structured airbag arch lock structure that can precisely adjust the raising and flattening of the blanket according to the internal temperature of the blanket, without reducing the comfort of the bedding. It also effectively prevents excessive internal temperature of the blanket during sleep, avoiding sweating and overheating, thus preventing chills and colds, and improving overall comfort.

[0005] To achieve the above objectives, the technical solution of this application is: an airbag arch lock structure, including a strip-shaped fixing band, on the surface of which multiple arch lock airbags are sequentially fixed, with equally spaced airbag gaps between adjacent arch lock airbags, and the cavities of adjacent arch lock airbags are connected by an airflow channel, with an inflation inlet provided on one or more arch lock airbags, the inflation inlet being connected to an inflation pump via an inflation tube, and a movable connector being provided between two adjacent arch lock airbags.

[0006] Furthermore, the movable connector includes a movable connecting piece, an insertion slot, and an insertion end. The movable connecting piece is a thin sheet structure. One end of the movable connecting piece has an insertion slot, and the other end of the movable connecting piece is the insertion end. After passing through the insertion slot, the insertion end is fixed to the outer wall of the airlock. The end with the insertion slot is fixed to the outer wall of another adjacent airlock. The middle part of the movable connecting piece is connected and fixed to the surface of the strip-shaped fixing band.

[0007] Furthermore, the end of the lock airbag that is in contact with the adjacent lock airbag is provided with a rounded end of the airbag, and the sides of the lock airbag are respectively provided with rounded side of the airbag.

[0008] Furthermore, an air extraction port is provided on the side of the lock airbag away from the inflation inlet, or an air extraction port is provided on the lock airbag away from the inflation inlet.

[0009] Furthermore, the air extraction port is connected to one end of the air extraction pipe, and the other end of the air extraction pipe is connected to the air extraction pump.

[0010] Furthermore, the movable connector is made of a fabric or elastic sheet with a certain degree of toughness.

[0011] Furthermore, the arch-lock airbag is provided with an exhaust port, and a solenoid valve is installed on the exhaust port.

[0012] The beneficial effects of this application are: 1. This application has multiple arched airbags fixedly arranged sequentially on the surface of the strip-shaped fixing belt. There are appropriate and equally spaced gaps between adjacent arched airbags. Each airbag is connected to the others. The air pump precisely pumps in air to compress the adjacent arched airbags, causing the airbags to arch and thus causing the bedding to arch to a certain height. At the same time, the airbags are precisely controlled to release air through a solenoid valve or an air pump to flatten the bedding.

[0013] 2. This application has a movable connector between two adjacent arch-lock airbags, which allows each arch-lock airbag to move synchronously and in coordination when inflating and deflating, and can significantly increase the lifting force when the airbag is arched. When the airbag rapidly reduces the air pressure, the quilt can slowly flatten out, improving the comfort of use.

[0014] 3. This application has a reasonable structure and can accurately adjust the arching and flattening of the quilt according to the internal temperature of the quilt, thereby regulating the internal temperature of the quilt without reducing the comfort of the bedding. At the same time, it can effectively avoid the situation of sweating and overheating due to excessive internal temperature of the quilt while sleeping, and will not cause catching a cold or getting chilled, thus improving the comfort of use.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 11 This application discloses an airbag arch lock structure, comprising a strip-shaped fixing band 1, characterized in that: a plurality of arch lock airbags 2 are sequentially fixed on the surface of the strip-shaped fixing band 1, and an equally spaced airbag gap 5 is provided between adjacent arch lock airbags 2, the cavities of adjacent arch lock airbags 2 are connected by an airflow channel 6, one or more arch lock airbags 2 are provided with an inflation inlet 7, the inflation inlet 7 is connected to an inflation pump 9 via an inflation pipe 8, and a movable connector is provided between two adjacent arch lock airbags 2.

[0029] The movable connector includes a movable connecting piece 14, an insertion slot 15, and an insertion end 16. The movable connecting piece 14 is a thin sheet structure. One end of the movable connecting piece 14 has an insertion slot 15, and the other end of the movable connecting piece 14 is the insertion end 16. After passing through the insertion slot 15, the insertion end 16 is fixed to the outer wall of the arch-lock airbag 2. The end with the insertion slot 15 is fixed to the outer wall of another adjacent arch-lock airbag 2. The middle part of the movable connecting piece 14 is connected and fixed to the surface of the strip-shaped fixing band 1.

[0030] The end of the arch lock airbag 2 that is in contact with the adjacent arch lock airbag 2 is provided with an airbag end rounded corner 3, and the two sides of the arch lock airbag 2 are respectively provided with airbag side rounded corners 4.

[0031] An air extraction port 10 is provided on the side of the airlock 2 away from the inflation inlet 7, or an air extraction port 10 is provided on the airlock 2 away from the inflation inlet 7.

[0032] The air extraction port 10 is connected to one end of the air extraction pipe 11, and the other end of the air extraction pipe 11 is connected to the air pump 12.

[0033] The arch-lock airbag 2 is provided with an exhaust port, and a solenoid valve 13 is installed on the exhaust port.

[0034] This application addresses the issue of arching and flattening in lightweight items such as bedding by employing an airbag arch-lock structure composed of multiple airbag units. Arching is achieved by inflating each airbag unit, and flattening is achieved by deflating each airbag unit to reduce air pressure. This design eliminates the need for complex mechanical transmission structures, offers good installation compatibility, distributes force evenly, provides fast response, and facilitates precise control. The specific structure is as follows: The strip-shaped fixing band 1 is used to connect and fix the airbags. Multiple locking airbags 2 are sequentially fixed on the same side surface of the strip-shaped fixing band 1, with a certain distance between adjacent locking airbags 2. This distance is generally 2 mm to 10 mm. The distance between the strip-shaped fixing bands 1 on the same strip should not be too large or too small. If the distance is too large, the adjacent airbags will not be able to compress each other, and if the distance is too small, the airbag's regulating effect will be weakened.

[0035] The airbag 2 is made of rubber or plastic with a certain degree of elasticity, or of a polymer material with a certain degree of elasticity and pressure resistance, such as polyurethane. The cavities of each airbag 2 are independently set. The connection and fixation between the strip-shaped fixing band 1 and the airbag 2 can adopt various structural forms. One is that one side of each airbag 2 is bonded and fixed to the surface of the strip-shaped fixing band 1; another is that the airbag components without a bottom surface are bonded and fixed to the surface of the strip-shaped fixing band 1, so that the strip-shaped fixing band 1 becomes part of the airbag 2; it can also be integrally molded.

[0036] The cavities of adjacent airlock airbags 2 are connected by an airflow channel 6, which is located inside the strip-shaped fixing band 1. The airflow channel 6 can be in the form of a pipe or a pre-reserved channel. If a one-piece molded structure is used, the pre-reserved channel structure is more convenient and economical.

[0037] To enable synchronized and coordinated operation of the various airbags 2 and increase the lifting force when the airbags are inflated, this application provides a movable connector between two adjacent airbags 2. The movable connector can effectively connect and restrain two adjacent airbags 2, and provide a certain restraining effect between the two adjacent airbags 2, which is beneficial for the coordinated operation of the various airbags 2. The movable connector includes a movable connecting piece 14, an insertion slot 15, and an insertion end 16. The movable connecting piece 14 is a thin sheet structure. One end of the movable connecting piece 14 has an insertion slot 15, and the other end of the movable connecting piece 14 is an insertion end 16. After passing through the insertion slot 15, the insertion end 16 is fixed to the outer wall of the airbag 2. The end with the insertion slot 15 is fixed to the outer wall of another adjacent airbag 2. The middle part of the movable connecting piece 14 is connected and fixed to the surface of the strip fixing band 1 by adhesive or sewing.

[0038] Each airlock bladder 2 is equipped with an inflation inlet 7. Only one inflation inlet 7 is needed on each airlock bladder 2 located on the same strip-shaped fixing band 1. The inflation inlet 7 is connected to an air pump 9 via an inflation pipe 8. The air pump 9 pumps air into the airlock bladder 2. By controlling the start / stop and operating time of the air pump 9, the air pressure inside each airlock bladder 2 can be precisely controlled. After a certain amount of air is pumped into the airlock bladder 2, compression occurs between adjacent airlock bladders 2. Since one side of the strip-shaped fixing band 1 cannot deform, the strip-shaped fixing band 1 and the strip structure formed by multiple airlock bladders 2 will bend inward, thus creating an arch. This will raise the entire quilt fixed to it to a certain height. The higher the air pressure inside the airlock bladder 2, the higher the arch height, although there is a maximum limit. This can reduce the pressure of the quilt on the body to some extent.

[0039] An air extraction port 10 is provided on the side of the airlock bladder 2 away from the inflation inlet 7, or an air extraction port 10 is provided on the airlock bladder 2 away from the inflation inlet 7. The air extraction port 10 is connected to one end of the air extraction pipe 11, and the other end of the air extraction pipe 11 is connected to the air extraction pump 12. Alternatively, the air extraction pump 12 may not be provided, but only an exhaust port is provided on the airlock bladder 2. A solenoid valve 13 is installed on the exhaust port. Controlling the solenoid valve can accurately control the exhaust of the airlock bladder 2, so that after the airlock bladder 2 expels some air, the quilt will automatically fall and flatten under the action of gravity.

[0040] In use, this application precisely controls the arching and flattening of the bedding by adjusting the air pressure within the arch-lock airbag 2. When the bedding arches to a certain height, it increases the space inside and allows some outside air to enter, alleviating the stuffiness inside the bedding. When the air pressure within the arch-lock airbag 2 is reduced, allowing the bedding to flatten under gravity, air is slowly expelled, thus appropriately lowering the internal temperature and improving sleep comfort. This fundamentally prevents sweating during sleep and the need to throw off the covers, preventing catching a cold in the middle of the night.

[0041] The above description is a further detailed explanation of this application in conjunction with specific embodiments. It should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, there will be various simple substitutions, improvements and changes to this application without departing from the concept of this application. All such simple substitutions, improvements and changes should be considered to fall within the protection scope of this application.
