Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to an air curtain enclosure component and a vehicle. Background Technology

[0002] Vehicle pop-up roof systems typically include a rigid enclosure. The vehicle roof is connected to the body via this rigid enclosure. During the roof raising process, a motor elevates the rigid enclosure until the roof reaches its maximum height, ensuring sufficient interior space for passengers to walk upright. During the roof lowering process, the motor lowers the rigid enclosure until the roof is completely closed. However, rigid enclosures require excessive storage space after lowering, occupying too much interior space. They are also expensive, heavy, have poor airtightness, and are costly to replace, making widespread adoption difficult. Utility Model Content

[0024] The following description, with reference to the accompanying drawings, describes an air curtain enclosure assembly 100 according to an embodiment of the present invention.

[0025] Reference Figures 1-11 As shown, the air curtain enclosure assembly 100 according to an embodiment of the present invention is used in the roof lifting system of a vehicle 1000. The air curtain enclosure assembly 100 may include an enclosure body 10 and an air nozzle 20. The vehicle 1000 may be a motorhome, a vehicle with special multi-purpose uses, or other types of vehicles. That is, the air curtain enclosure assembly 100 according to an embodiment of the present invention can be used in motorhomes, vehicles with special multi-purpose uses, or other types of vehicles.

[0026] Specifically, the enclosure body 10 includes multiple airbags 11 connected in sequence. Inflating the airbags 11 causes them to bulge, and deflating them causes them to contract for storage. The interconnected airbags 11 are internally connected, so inflating one airbag 11 simultaneously inflates all airbags 11, and deflating one airbag simultaneously contracts all airbags 11. This results in better overall consistency of the enclosure body 10, more uniform inflation and deflation, more consistent deformation of different parts of the enclosure body 10, and easier operation.

[0027] like Figure 1 As shown, the top of the enclosure body 10 is connected to the roof 300 of the vehicle 1000, and the bottom is connected to the body 200 of the vehicle 1000. The roof 300 is a liftable cover, located on the upper side of the body 200, with the body 200 serving as the base for the liftable cover. The inner side of the enclosure body 10 defines a lifting space 101, which communicates with the passenger compartment within the body 200. When the roof 300 is raised away from the body 200, the enclosure body 10 can enclose the space between the roof 300 and the body 200. The lifting space 101 is isolated from the outside through the enclosure body 10, making it less prone to air leakage and providing better protection, allowing users inside the vehicle 1000 to walk upright within the enclosure body 10. Alternatively, when the roof 300 is lowered closer to the body 200, the top of the vehicle 1000 is completely closed, facilitating the storage of the enclosure body 10.

[0028] Airbag 11 can extend circumferentially along the roof 300 or vertically along the vehicle 1000 (e.g.) Figures 1-11 Extending in the vertical direction (as shown). For example, in some embodiments, such as Figures 1-10 As shown, multiple airbags 11 are stacked and connected sequentially along the height direction of the vehicle 1000, and the airbags 11 extend in a ring shape along the circumference of the roof 300, forming a continuous ring. This allows the multiple airbags 11 to inflate or contract along the stacking direction, i.e., the height direction of the vehicle 1000, and also allows the enclosure body 10 to form a structure similar to the bellows of an accordion. The enclosure body 10 has a good effect in expanding or contracting along the height direction of the vehicle 1000 and is not prone to tilting.

[0029] The extension direction of each airbag 11 intersects the height direction of the vehicle 1000, allowing the enclosure body 10 to form various shapes to adapt to different vehicle 1000 models, and the vertical landing effect of the airbags 11 is good. For example Figures 2-6 As shown, a portion of the airbag 11 extends horizontally and another portion extends from back to front and downward at an angle.

[0030] In other embodiments, such as Figure 11 As shown, multiple airbags 11 are arranged circumferentially along the roof 300 and connected sequentially, extending along the height direction of the vehicle 1000. This allows the multiple airbags 11 to inflate or deflate along the height direction of the vehicle 1000, and each airbag 11 can inflate to a greater height, enabling the enclosure body 10 to meet the protection requirements of higher roof heights. By adjusting the shape and number of airbags 11, the enclosure body 10 can be formed into various shapes to adapt to different vehicle 1000 models, thus broadening its applicability. For example... Figure 11 As shown, a portion of the enclosure body 10 extends horizontally and another portion extends from back to front and downwards at an angle.

[0031] An air nozzle 20 is disposed in the enclosure body 10 and communicates with the interior of the airbag 11. There can be one or more air nozzles 20. Each air nozzle 20 can be disposed in any one of the multiple airbags 11 within the enclosure body 10. For example... Figure 2 The two air nozzles 20 shown are both located on the lowest airbag 11 to communicate with the interior of the lowest airbag 11, and thus communicate with the multiple airbags 11 connected to the interior.

[0032] Air nozzles 20 are used to inflate or deflate airbags 11, allowing the enclosure body 10 to have both deployed and retracted states. The height of the lifting space 101 in the deployed state is greater than its height in the retracted state. Specifically, air nozzles 20 inflate the airbags 11, causing multiple airbags 11 to expand along the height direction, raising the roof 300 and switching the enclosure body 10 to the deployed state. In the deployed state, the multiple airbags 11 expand along the height direction of the vehicle 1000 to accommodate the roof 300 rising away from the vehicle body 200 along the height direction. This also increases the rigidity of the airbags 11, improving the rigidity of the enclosure body 10, enhancing its wind resistance, making it less prone to being blown down by the wind, facilitating upright walking inside the vehicle, and improving safety. Changing the number of airbags 11 alters the height of the enclosure body 10, making the height of the roof 300 adjustable to meet different user needs regarding the roof height.

[0033] For example, in some embodiments, such as Figures 1-10 As shown, multiple airbags 11 are stacked and connected sequentially along the height direction of the vehicle 1000. The airbags 11 extend in a ring along the circumference of the roof 300. When deployed, the height of the protective body 10 is less than or equal to 0.35m, which is more conducive to enhancing the windproof performance of the protective body 10. For example, in some other embodiments, such as Figure 11 As shown, multiple airbags 11 are arranged circumferentially along the roof 300 and connected sequentially. The airbags 11 extend along the height direction of the vehicle 1000. When deployed, the height of the protective body 10 is greater than 0.35m, which is more conducive to increasing the lifting height of the roof 300. For example, the height of the protective body 10 when deployed is 0.35m, 1m, 1.2m or 1.5m, etc.

[0034] When deployed, the airbag 11 is filled with gas, creating an air wall between the main enclosure 10 and the base at the bottom of the roof. In other words, an air wall is formed between the roof 300 and the vehicle body 200 by the airbag 11, which separates the interior of the vehicle 1000 from the outside, thus ensuring the unique properties of heat preservation, sound insulation, moisture prevention, and waterproofing inside the vehicle.

[0035] Air inlet 20 draws air into airbags 11, causing multiple airbags 11 to contract along the height direction, and the roof 300 descends, switching the main body of the enclosure 10 to a retracted state. In the retracted state, the multiple airbags 11 contract and stack along the height direction of the vehicle 1000, so that the roof 300 descends closer to the vehicle body 200 along the height direction. This gives the curtain wall enclosure assembly 100 deformable and freely foldable properties, which can reduce the storage space required for the curtain wall enclosure assembly 100 in the retracted state, reduce the space occupied in the vehicle interior, and make the structure of the vehicle 1000 more compact.

[0036] In some related technologies, the vehicle roof and body are typically connected by a rigid enclosure. This rigid enclosure is non-deformable and non-foldable, thus requiring a large installation space for raising and lowering it. Furthermore, rigid enclosures are expensive, heavy, have poor airtightness, and are costly to replace.

[0037] In this application, the roof 300 and the vehicle body 200 are connected by the enclosure body 10. The enclosure body 10 includes multiple interconnected airbags 11. The airbags 11 are inflated or deflated through air nozzles 20, giving the enclosure body 10 both an deployed and a retracted state. In the deployed state, all airbags 11 inflate along the height of the vehicle 1000. The enclosure body 10 has good rigidity and protective performance, and forms an air wall between the lifting space 101 and the outside, which helps improve the insulation, soundproofing, moisture-proofing, and waterproofing of the vehicle interior, and provides strong airtightness. In the retracted state, all airbags 11 contract along the height of the vehicle 1000, making the space occupied by all airbags 11 small after being retracted, and facilitating storage. Therefore, the enclosure body 10 not only has good protective performance, but also has deformable and foldable properties, which can reduce the installation space required for the air curtain enclosure component 100.

[0038] The airbag 11 can be made of soft fabric so that it inflates when inflated and deflates when deflated. For example, the airbag 11 can be made of TPU composite material or other materials, as long as the airbag 11 can inflate when inflated and deflate when deflated. Among them, TPU is thermoplastic polyurethane, and TPU composite material refers to a new type of material that uses thermoplastic polyurethane (TPU) as a matrix or main component and combines it with one or more other materials through physical or chemical methods.

[0039] Preferably, the airbag 11 is made of TPU composite material. In embodiments where the airbag 11 is made of TPU composite material, the TPU composite material has the characteristics of wear resistance, aging resistance, strong airtightness, resistance to deformation, resistance to fading, and light weight. This makes the TPU composite material have strong tear resistance and load-bearing capacity, making the airbag 11 less prone to permanent deformation or even rupture. It also improves the wear resistance of the airbag 11, which helps to extend the service life of the airbag 11 and enhance the protective performance of the enclosure body 10 in the deployed state. Furthermore, it can reduce the load-bearing mass of the lifting roof system in the deployed state of the enclosure body 10, thereby enhancing the stability and safety of the vehicle body in this state. For example, the TPU composite material is a composite material including thermoplastic polyurethane (TPU) and fiber cloth. Thermoplastic polyurethane (TPU) has good thermoplastic shaping properties, and the fiber cloth has strong flexibility, giving the TPU composite material the characteristics of wear resistance, aging resistance, strong airtightness, resistance to deformation, resistance to fading, and light weight.

[0040] The airbag 11 is made of inexpensive materials, is easy to manufacture, and is lightweight and easy to transport, which makes the air curtain enclosure component 100 cheaper, lighter, and easier to replace, and thus easier to promote and use.

[0041] According to the embodiment of this utility model, the air curtain enclosure component 100 is composed of a plurality of airbags 11 connected in sequence to form an enclosure body 10. The airbags 11 are inflated or deflated through the air nozzles 20, so that the enclosure body 10 has an unfolded state and a retracted state. The enclosure body 10 has better protective performance in the unfolded state and occupies less space in the retracted state. This helps to reduce the space occupied, manufacturing cost, replacement cost and weight of the air curtain enclosure component 100, making it more practical and easier to promote and use. Moreover, the enclosure body 10 can form an air wall between the roof 300 and the vehicle body 200, thereby ensuring the unique characteristics of heat preservation, sound insulation, moisture prevention and waterproofing inside the vehicle compartment, and strong airtightness.

[0042] In some embodiments of this utility model, such as Figures 7-8 As shown, the connection between two adjacent airbags 11 is recessed towards the inside of the airbag 11, so that the connection between two adjacent airbags 11 is less likely to deform after the airbag 11 is inflated, which helps to improve the connection strength between two adjacent airbags 11 and thus improve the connection strength of all airbags 11.

[0043] Each airbag 11 bulges outward from its center along the height direction, allowing adjacent airbags 11 to stack along the height direction after air is drawn into them. This ensures that multiple airbags 11 are stacked sequentially along their center along the height direction, preventing any single airbag 11 from exceeding the height of its adjacent airbags in the horizontal direction. This results in good vertical descent of the enclosure body 10 and facilitates storage. The outer side of the airbag 11 refers to the side of the airbag 11 facing or away from the lifting space 101.

[0044] In some embodiments, the hardness of the connection between each airbag 11 and the adjacent airbag 11 is greater than the hardness of other parts, so that the concave part of each airbag 11 facing inward has higher hardness and is not easy to deform, which is beneficial to improve the connection strength of adjacent airbags 11 and makes it less likely for adjacent airbags 11 to shift in other directions after being stacked in the storage state, which is beneficial to improve the storage effect of multiple airbags 11.

[0045] For example Figures 7-8 As shown, the hardness of the concave part of each airbag 11 is higher than that of the middle part along the height direction. In the storage state, multiple airbags 11 are easier to store along the height direction and are less likely to tilt in other directions, which facilitates storage.

[0046] For example, in some embodiments, two adjacent airbags 11 are connected by a hot-pressing process. The hot-pressed area has a higher hardness, making the hardness of the connection between each airbag 11 and its adjacent airbag 11 greater than the hardness of other parts, and it is easy to operate.

[0047] In some embodiments, such as Figures 7-8As shown, each airbag 11 includes a first portion 111 and a second portion 112 arranged in the height direction, and the first portion 111 and the second portion 112 are connected by a hot pressing process to form the airbag 11. The operation is convenient, and the hardness of the hot-pressed position is relatively high, so that the connection between the first portion 111 and the second portion 112 has high hardness and is not prone to deformation, which is beneficial to improving the overall connection strength of the airbag 11, and enables the first portion 111 and the second portion 112 of each airbag 11 to be stacked in the height direction in the stored state, which is not easy to skew in other directions and is convenient for storage.

[0048] In some embodiments of the present utility model, as Figures 7-8 shown, in the deployed state, in the cross-sectional shape of each airbag 11 perpendicular to its extension direction, the dimension along the height direction of the vehicle 1000 (for example Figures 7-8 the up-down direction shown) is L1, and in the cross-sectional shape of each airbag 11 perpendicular to its extension direction, the dimension perpendicular to the height direction of the vehicle 1000 (for example Figures 7-8 the left-right direction shown) is L2, where L1<L2. The cross-sectional shape of each airbag 11 perpendicular to its extension direction is relatively flat, which is beneficial to increasing the base area of the enclosing main body 10 and lowering the center of gravity of each airbag 11, so that the stacked airbags 11 are more stable and less prone to collapse, high stacking sealing can be achieved in the stacking direction of the plurality of airbags 11, which is convenient for storage, and the rigidity of the enclosing main body 10 in the deployed state is also higher.

[0049] For example, in some embodiments, as Figures 7-8 shown, one part of the airbag 11 extends in the horizontal direction, and the other part extends obliquely downward from the back to the front. For the horizontally extending part of the airbag 11, in the deployed state, in the vertical cross-section of each airbag 11, the dimension in the up-down direction is L1, and the dimension in the left-right direction is L2, where L1<L2, so that the airbag 11 is formed into a relatively flat shape with larger areas on the upper and lower sides.

[0050] In some embodiments of the present utility model, as Figures 2-4 and Figures 9-10 shown, the air curtain enclosure assembly 100 further includes a base 30, the base 30 includes a seat body portion 31 and a storage portion 32, the seat body portion 31 is located on the lower side of the enclosure main body 10 and connected to the bottom of the enclosure main body 10, and the enclosure main body 10 can be supported by the seat body portion 31 to improve the working stability of the enclosure main body 10. The connection area between the seat body portion 31 and the enclosure main body 10 is large, the connection strength is high, and the seat body portion 31 is connected to the vehicle body 200, the enclosure main body 10 can be firmly installed on the vehicle body 200 through the seat body portion 31, which is beneficial to improving the connection strength between the air curtain enclosure assembly 100 and the vehicle 1000.

[0051] The storage section 32 is located on the outer side of the enclosure body 10 away from the lifting space 101. The storage section 32 extends continuously along the circumference of the enclosure body 10 to define a storage space. The enclosure body 10 in the storage state is stored in the storage space. Through the continuously extending storage section 32, any part of the enclosure body 10 can be stored along the circumference of the roof 300, so that the enclosure body 10 in the storage state is completely stored in the storage space. The enclosure body 10 in the storage state is not easily exposed to the outside. The storage effect of stacking the enclosure body 10 along the height direction is better.

[0052] This application allows for manual control of the air nozzle 20 to inflate or deflate the airbag 11, or it can be equipped with an electronic control component to automatically inflate or deflate the airbag 11. For example, in some embodiments, the curtain air closure assembly 100 also includes an air pump connected to the air nozzle 20 to inflate or deflate the airbag 11. The air pump can be connected to the control system of the vehicle 1000. The air pump enables the air nozzle 20 to automatically inflate or deflate the airbag 11, saving manpower. Furthermore, the user can automatically control the air pump within the vehicle 1000 via the control system to achieve automatic inflation or deflation of the airbag 11, making operation convenient.

[0053] like Figure 1 As shown, the vehicle 1000 according to an embodiment of the present invention includes a vehicle body 200, a vehicle roof 300, and an air curtain enclosure assembly 100 according to an embodiment of the present invention. The enclosure body 10 is connected between the vehicle roof 300 and the vehicle body 200, and the lifting space 101 is connected to the space inside the vehicle body 200. The vehicle 1000 can be a motorhome, a vehicle with special multi-functional purposes, or other types of vehicles.

[0054] Since the air curtain enclosure component 100 according to the present utility model has the above-mentioned beneficial technical effects, the vehicle 1000 according to the present utility model is composed of a plurality of airbags 11 connected in sequence to form an enclosure body 10. The airbags 11 are inflated or deflated through the air nozzles 20, so that the enclosure body 10 has an unfolded state and a retracted state. The protective performance of the enclosure body 10 is better in the unfolded state, and the space occupied by the enclosure body 10 is smaller in the retracted state. This helps to reduce the space occupied, manufacturing cost, replacement cost and weight of the air curtain enclosure component 100, making it more practical and easier to promote and use. Moreover, the enclosure body 10 can form an air wall between the roof 300 and the vehicle body 200, thereby ensuring the unique characteristics of heat preservation, sound insulation, moisture prevention and waterproofing inside the vehicle compartment, and strong airtightness.

[0055] In some embodiments of this utility model, such as Figures 1-4 and Figure 9As shown, the vehicle 1000 also includes a lifting assembly 400, with its two ends connected to the roof 300 and the body 200, respectively. The lifting assembly 400 is used to adjust the height of the roof 300. For example, the lifting assembly 400 can be used to drive the roof 300 away from the body 200 to rise, or to drive the roof 300 closer to the body 200 to lower. There can be one or more lifting assemblies 400.

[0056] The height of the roof 300 is adjusted by the lifting assembly 400, and the roof 300 and the vehicle body 200 are connected circumferentially by the air curtain enclosure assembly 100. When the roof 300 is raised to its highest position by the lifting assembly 400, the unfolded enclosure body 10 can separate the lifting space 101 from the outside world, thereby improving the protective performance of the lifting space 101. When the roof 300 is lowered to its lowest position to close the top of the vehicle 1000, the enclosed enclosure body 10 can be stored in a smaller installation space, resulting in a highly compact structure for the vehicle 1000.

[0057] The lifting assembly 400 may include one or more components such as a motor, a slide bar, and a slider, which can drive the roof 300 to rise and fall.

[0058] In some embodiments, the lifting assembly 400 is configured to raise the roof 300 to a predetermined height before the air nozzle 20 inflates the airbag 11. This predetermined height is less than the height difference between the lifting space 101 in its deployed and retracted states. When the roof 300 is lowered to its lowest position, the top of the vehicle 1000 is completely closed, the enclosure body 10 is in its retracted state, and the height of the lifting space 101 is its lowest point. When the roof 300 is raised to its highest position, the enclosure body 10 is in its deployed state, and the height of the lifting space 101 is its maximum height, facilitating upright walking for users inside the vehicle 100 within the lifting space 101. When the roof 300 is raised to the predetermined height, the height of the lifting space 101 is between its maximum and lowest points.

[0059] With the roof 300 lowered to its lowest position, different parts of the inner wall of each airbag 11 are in contact with each other, making it difficult to inflate the airbag 11. However, this application inflates the airbag 11 through the air nozzle 20 after the lifting assembly 400 raises the roof 300 to a set height. This allows inflation of the airbag 11 without the different parts of the inner wall of each airbag 11 being in contact, enabling the gas to distribute more quickly to the different parts of the multiple interconnected airbags 11, resulting in higher inflation efficiency.

[0060] When the roof 300 is raised to its highest position, the airbag 11 deforms significantly along its height. At this point, without any gas inside, the airbag 11 has low stiffness, making it prone to rupture. This application addresses this by inflating the airbag 11 via the air nozzle 20 after the lifting assembly 400 raises the roof 300 to a set height. This allows the airbag 11 to be inflated before the roof 300 reaches its highest position, increasing its stiffness, reducing the risk of rupture, and extending its lifespan.

[0061] Therefore, the lifting assembly 400 is configured to drive the roof 300 to rise to a set height before the air nozzle 20 inflates the airbag 11, so that after the lifting assembly 400 drives the roof 300 to rise to the set height, the air nozzle 20 inflates the airbag 11. This can improve the inflation efficiency of the airbag 11 and extend the service life of the airbag 11, and is quite feasible.

[0062] In some embodiments, the lifting assembly 400 is configured to drive the roof 300 to rise during the inflation of the airbag 11 by the air nozzle 20 until the protective body 10 switches to the deployed state. This allows the roof 300 to rise while the airbag 11 is being inflated, gradually increasing the stiffness of the airbag 11 until the protective body 10 switches to the deployed state. At this point, the roof 300 is at its highest position, the airbag 11 has high stiffness, making it less prone to rupture and improving the protective performance of the protective body 10.

[0063] For example, during the process of the roof 300 rising from its lowest position to its highest position, the main body 10 of the enclosure is in a retracted state when the roof 300 is at its lowest position. First, the roof 300 is raised to a set height by the lifting assembly 400. Then, air is simultaneously inflated into the airbag 11 through the air nozzle 20, causing the airbag 11 to begin to expand. The roof 300 is then raised further by the lifting assembly 400 until the roof 300 reaches its highest position, at which point the main body 10 switches to the deployed state.

[0064] In some embodiments, such as Figures 1-4 and Figure 9 As shown, at least a portion of the lifting assembly 400 is located in the lifting space 101, which can reduce the space outside the vehicle body 200 for installing the lifting assembly 400, allowing more installation space in the vehicle body 200 to be used for installing the air curtain enclosure assembly 100, which is beneficial to increasing the size of the lifting space 101, and making the space inside the vehicle 1000 available for users to walk upright larger.

[0065] Other configurations and operations of the air curtain enclosure assembly 100 and the vehicle 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
