Description

Technical Field

[0001] This utility model relates to the field of inflatable products, and in particular to an inflatable sled. Background Technology

[0002] Skiing is a popular winter sport. Specialized skiing equipment is required for skiing, and sleds are a common type of equipment. Existing skiing equipment on the market includes wooden sleds, rigid plastic sleds, and PVC inflatable sleds. However, wooden and rigid plastic sleds are expensive, heavy, and bulky, making them inconvenient to carry. PVC inflatable sleds also have several problems. For example, due to the use of PVC film, which is flexible but lacks rigidity, it deforms after inflation, resulting in high friction and insufficient rigidity, affecting performance. In snowy conditions, the material becomes more brittle, making it prone to cracking or breaking. PVC sleds are only for use on snow, lack directional control, and have no side protection, making them prone to tipping over and causing danger. Furthermore, existing sleds lack anti-slip devices, and the snow inside the sled can easily become wet and slippery. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] refer to Figure 1This application provides an inflatable sled 100, which includes an inflatable base 200 (belonging to the base portion of the inflatable sled 100) and an inflation tube 300. The inflation tube 300 is arranged around the inflatable base 200 to form a fence around the inflatable sled 100, thereby defining a cabin 400 together with the inflatable base 200, which provides a riding space for the user.

[0029] In this embodiment, the inflatable base 200 includes a wire-drawing material body 201, which includes a first end face 201a and a second end face 201b. The first end face 201a and the second end face 201b are arranged opposite to each other and parallel to each other along the thickness direction Z of the inflatable base 200. The first end face 201a faces upward along the thickness direction Z to support the user, and a portion of the second end face 201b is used to contact the ground.

[0030] Specifically, such as Figure 1 As shown, an anti-slip pad 401 is attached to the first end face 201a of the drawing material body 201, allowing the user inside the cabin 400 to sit directly on the anti-slip pad 401, increasing the user's stability within the cabin 400 and preventing them from sliding inside the cabin 400 during the gliding of the inflatable sled 100. Exemplarily, the anti-slip pad 401 is made of EVA (Ethylene-Vinyl Acetate Copolymer), which is high-frequency welded or bonded to the first end face 201a of the drawing material body 201. However, those skilled in the art will understand that in other embodiments, the anti-slip pad 401 may also be made of other materials, such as rubber.

[0031] Furthermore, the cockpit 400 is provided with three anti-slip pads 401 spaced apart along the length X of the inflatable base 200. However, those skilled in the art will understand that the number of anti-slip pads 401 can be set according to actual needs and the length of the cockpit 400. For example, when the cockpit 400 is long, the anti-slip pads 401 can also be set to four, five, etc.

[0032] For example, such as Figure 2 and Figure 3 As shown, the second end face 201b is provided with a guide 500, which extends along the length direction X of the inflatable base 200 to keep the inflatable sled 100 sliding along its length direction X and prevent it from deviating.

[0033] like Figure 4As shown, in this embodiment, the guide member 500 is T-shaped, which provides clear directional guidance when the inflatable sled 100 is gliding, ensuring that the inflatable sled 100 moves along a predetermined straight trajectory, reducing lateral deviation and swaying. On the other hand, the T-shaped guide member 500 can improve grip and reduce the risk of tipping over. However, those skilled in the art will understand that in other embodiments, the guide member 500 may also be other shapes, such as triangular shapes.

[0034] Optionally, the guide 500 in this embodiment is made of rigid plastic.

[0035] like Figure 2 As shown, the second end face 201b of the drawing material body 201 of the inflatable base 200 in this embodiment is provided with four guide members 500 distributed in a rectangular shape. However, those skilled in the art will understand that in other embodiments, other numbers of guide members 500 may also be provided, such as 1 or 3.

[0036] Continue to refer to Figure 2 The second end face 201b of the filament body 201 of the inflatable base 200 is provided with a towing ring 700, which makes it convenient for the user to connect a towing rope and use human power or mechanical power such as a snowmobile to tow the inflatable sled 100 to the required location when it needs to be moved a long distance.

[0037] Furthermore, the second end face 201b of the filament body 201 of the inflatable base 200 is provided with a wear-resistant layer 207. For example, when the inflatable sled 100 slides on the snow, there may be sharp objects such as branches and stones in the snow. The wear-resistant layer 207 can resist the scratches of these objects on the inflatable base 200, protect the inflatable base 200 from damage, and maintain the integrity and performance of the inflatable sled 100.

[0038] For example, the wear-resistant layer 207 is made of TPU (Thermoplastic Polyurethane) or PVC (Polyvinyl Chloride).

[0039] like Figure 3 and Figure 5 As shown, those skilled in the art will understand that the inflatable base 200 is composed of a wire-drawn material body 201 (constituting the main body of the inflatable base 200, cut from wire-drawn material 240) and sidewalls 203. Specifically, the sidewalls 203 cover (are bonded or welded to) the outer edges of the first end face 201a and the second end face 201b of the wire-drawn material body 201 to define the air chamber 204 of the inflatable base 200. Specifically, as... Figure 6As shown, the wire drawing material 240 includes a first bonding sheet 250, a second bonding sheet 260, and multiple threads 270. The second bonding sheet 260 is arranged parallel to the first bonding sheet 250. The first bonding sheet 250 includes an inner layer 251 and an outer layer 252. Similarly, the second bonding sheet 260 includes an inner layer 261 and an outer layer 262. The inner layers 251 of the first bonding sheet 250 and the inner layers 261 of the second bonding sheet 260 are arranged opposite to each other. Multiple threads 270 are densely and evenly distributed across the distance between the first bonding sheet 250 and the second bonding sheet 260, and are connected by sewing to form a series of stitches 271.

[0040] Preferably, the outer layer 252 of the first bonding sheet 250 and the outer layer 262 of the second bonding sheet 260 are PVC or TPU layers, and the inner layer 251 of the first bonding sheet 250 and the inner layer 261 of the second bonding sheet 260 are fabric layers. The outer layer 252 and the inner layer 251 of the first bonding sheet 250, and the outer layer 262 and the inner layer 261 of the second bonding sheet 260, are bonded together by adhesive. The multiple threads 270 can be densely packed multiple filaments, which connect the inner layers 251 of the first bonding sheet 250 and the inner layers 261 of the second bonding sheet 260 by sewing, thereby forming a filament material 240.

[0041] It is understood that the outer layer 252 of the first bonding sheet 250 of the aforementioned wire drawing material 240 constitutes the first end face 201a of the wire drawing material body 201, and the outer layer 262 of the second bonding sheet 260 of the wire drawing material 240 constitutes the second end face 201b of the wire drawing material body 201.

[0042] In this embodiment, the inflatable base 200 is in the form of Figure 2 The hexagon shown has six sides that are connected end to end: the first side 200a, the second side 200b, the third side 200c, the fourth side 200d, the fifth side 200e, and the sixth side 200f.

[0043] Those skilled in the art will understand that although the inflatable base 200 is hexagonal in this embodiment, in other embodiments, the inflatable base 200 may also be circular, elliptical, boat-shaped, or other shapes.

[0044] Understandably, the first end face 201a and the second end face 201b of the filament body 201 of the hexagonal inflatable base 200 are also hexagonal. The aforementioned sidewall 203 surrounds the outer periphery of the first end face 201a and the second end face 201b and is sealed to the edges of the first end face 201a and the second end face 201b to close the outer periphery of the first end face 201a and the second end face 201b, thereby forming a closed air chamber 204 of the inflatable base 200. The first end face 201a is provided with an air valve 205, which can be used to inflate the air chamber 204 to expand it into a preset hexagonal plate shape, and to deflate it when not in use, so as to facilitate user storage and organization.

[0045] The filament body 201 helps the inflatable base 200 maintain the stability of the air chamber 204 during inflation. Furthermore, the filament body 201 can improve the structural strength of the inflatable sled 100, making it more robust and resistant to bending under stress during use. This allows the inflatable sled 100 to maintain a stable gliding posture on the snow, making gliding smoother, reducing the risk of tipping over, and ensuring user safety.

[0046] like Figure 3 and Figure 5 As shown, in this embodiment, the sidewall 203 includes two surrounding pieces 230, namely a sealing piece 230a and a reinforcing piece 230b. Both the sealing piece 230a and the reinforcing piece 230b include a first end A and a second end B disposed vertically opposite each other. The first end A of the sealing piece 230a is connected to a first end face 201a, and the second end B of the sealing piece 230a is connected to the second end face 201b, thus defining the air outlet chamber 204. The reinforcing piece 230b is located on the side of the sealing piece 230a outside the air chamber 204 and is in close contact with the sealing piece 230a. The first end A of the reinforcing piece 230b is also connected to the first end face 201a, and the second end B of the reinforcing piece 230b is also connected to the second end face 201b.

[0047] In this embodiment, a reinforcing sheet 230b is added to the sealing sheet 230a, thus providing two layers of surrounding sheets 230. On the one hand, this provides double sealing protection. For example, if the reinforcing sheet 230b is punctured by a sharp point during the gliding of the inflatable sled 100, the sealing sheet 230a can still continue to perform the sealing task of the air chamber 204. On the other hand, the double-layer surrounding sheets 230 can also increase the deformation resistance of the inflatable base 200, thereby maintaining the shape of the inflatable base 200.

[0048] For example, both the sealing sheet 230a and the reinforcing sheet 230b are connected to the first end face 201a and the second end face 201b by high-frequency welding or bonding, and the sealing sheet 230a and the reinforcing sheet 230b are also bonded together by high-frequency welding or bonding.

[0049] In this embodiment, each surrounding piece 230 is an integral elongated strip, arranged around the outer periphery of the inflatable base 200, and expands into a shape when inflated within the air chamber 204. Figure 5 The semi-circular shape is shown. However, those skilled in the art will understand that in other embodiments, the surrounding piece 230 can also be configured as multiple separate segments, with each segment connected to the first end face 201a and the second end face 201b, thereby similarly defining the air outlet chamber 204. Furthermore, this embodiment provides two surrounding pieces 230, but in other embodiments, other numbers of surrounding pieces 230 can be provided, such as one, three, etc.

[0050] like Figure 2 and Figure 7 As shown, the inflatable base 200 includes a head portion 210 and a tail portion 220 connected together, with the lower surface of the tail portion 220 used to contact the ground. In this document, "head" and "tail" correspond to the forward and backward positions of the inflatable sled 100 during its gliding process.

[0051] It is understandable that the lower surface of the tail portion 220 is part of the second end face 201b.

[0052] For example, such as Figure 2 As shown, the head portion 210 is in the shape of an isosceles trapezoid, and the tail portion 220 is in the shape of a rectangle. Thus, the head portion 210 and the tail portion 220 are connected together to form an inflatable base 200 with a hexagonal shape.

[0053] like Figure 7 As shown, the angle β between the head portion 210 and the tail portion 220 is an obtuse angle. Specifically, both the head portion 210 and the tail portion 220 are plate-shaped, and the angle β between the two planes containing their lower surfaces is an obtuse angle.

[0054] Specifically, the angle β between the head portion 210 and the tail portion 220 is 160° to 177°.

[0055] In other words, the head portion 210 is tilted upwards at a set angle α relative to the tail portion 220, with the set angle α ranging from 3° to 20°, making it less likely for snow and water to accumulate inside the cabin 400. Furthermore, this allows air to flow more smoothly over the surface of the inflatable sled 100 during gliding, reducing the air force on the sled 100, thereby reducing air resistance and increasing gliding speed. On the other hand, the tilted head portion 210 provides an upward component force when the inflatable sled 100 contacts the snow surface, reducing the possibility of the front end plunging into the snow and ensuring stable gliding of the inflatable sled 100 on the snow.

[0056] For example, the included angle β between the head portion 210 and the tail portion 220 can be 177°, 172°, 168°, 165°, 160°, etc., and the corresponding set angle α can be 3°, 8°, 12°, 15°, 20°, etc.

[0057] refer to Figure 1 and Figure 3 In this embodiment, the aforementioned inflation tube 300 is disposed on the first end face 201a and side wall 203 of the drawing material body 201 of the inflation base 200. Specifically, in this embodiment, a portion of the inflation tube 300 is connected to the first end face 201a, and another portion is connected to the side wall 203.

[0058] In other embodiments, the inflation tube 300 may be entirely disposed on the first end face 201a or side wall 203 of the drawing material body 201 of the inflation base 200. That is, the inflation tube 300 is only connected to the first end face 201a or side wall 203.

[0059] Specifically, such as Figure 1 and Figure 2 As shown, the inflation tube 300 includes a first side tube 310, a second side tube 320, and a connecting tube 330. The first side tube 310 is located on one side of the inflation base 200 in the width direction Y; the second side tube 320 is located on the other side of the inflation base 200 in the width direction Y; and the connecting tube 330 is located on one side of the inflation base 200 in the length direction X, and is located at the head portion 210 of the inflation base 200. The first side tube 310, the second side tube 320, and the connecting tube 330 form a U-shaped inflation tube 300. The length direction X is the direction of movement of the inflatable sled 100, and the width direction Y is perpendicular to the length direction X; the ends of the first side tube 310 and the second side tube 320 furthest from the connecting tube 330 are both closed.

[0060] Those skilled in the art will understand that the shape of the inflation tube 300 is not limited. In other embodiments, the first side tube 310, the second side tube 320, and the connecting tube 330 can also be arranged into other shapes of the inflation tube 300, such as triangular or semi-circular shapes.

[0061] For example, refer to Figure 1The first side tube 310 includes a first tube portion 310a and a second tube portion 310b, wherein the two ends of the first tube portion 310a are respectively connected to the connecting tube 330 and the second tube portion 310b, and the end of the second tube portion 310b away from the first tube portion 310a is closed. Correspondingly, the second side tube 320 includes a third tube portion 320a and a fourth tube portion 320b, wherein the two ends of the third tube portion 320a are respectively connected to the connecting tube 330 and the fourth tube portion 320b, and the end of the fourth tube portion 320b away from the third tube portion 320a is closed. Both the second tube portion 310b and the fourth tube portion 320b extend along the length direction X of the inflatable base 200, and the first tube portion 310a, the connecting tube 330, and the third tube portion 320a form an isosceles trapezoidal shape.

[0062] refer to Figure 1 and Figure 2 Corresponding to the hexagonal inflatable base 200, the inflation tubes 300 are arranged around the five sides of the inflatable base 200 to form a cabin 400 for users to sit in. Specifically, the connecting tube 330 of the inflation tube 300 is located on the first side 200a of the inflatable base 200, the first tube portion 310a of the first side tube 310 is located on the second side 200b of the inflatable base 200, the second tube portion 310b is located on the third side 200c of the inflatable base 200, the third tube portion 320a is located on the sixth side 200f of the inflatable base 200, and the fourth tube portion 320b is located on the fifth side 200e of the inflatable base 200.

[0063] That is, the fourth side 200d of the inflatable base 200 is not provided with an inflation pipe 300, thereby forming an opening 402 in the cabin 400. The opening 402 is located at the tail portion 220 of the inflatable base 200, and is provided opposite to and spaced apart from the connecting pipe 330 in the length direction X of the inflatable base 200, so that the user can enter the cabin 400 through the opening 402.

[0064] In this embodiment, the top 300a of the inflation tube 300 is higher than the first end face 201a. Specifically, the tops of the connecting tube 330, the first tube portion 310a, the second tube portion 310b, the third tube portion 320a, and the fourth tube portion 320b are all higher than the first end face 201a, thereby acting as a barrier for the user sitting in the cabin 400, preventing the user from sliding out or falling out of the cabin 400 during skiing, thus increasing safety and stability.

[0065] refer to Figure 1 and Figure 3For example, the cross-sections of the connecting pipe 330, the first pipe section 310a, the second pipe section 310b, the third pipe section 320a, and the fourth pipe section 320b are all circular. The ends of the second pipe section 310b and the fourth pipe section 320b that are away from the connecting pipe 330 are closed by high-frequency welding or bonding of a circular piece 340 to their ends. However, those skilled in the art will understand that the ends of the second pipe section 310b and the fourth pipe section 320b that are away from the connecting pipe 330 can also be closed by other means, such as by directly tying their ports with cable ties.

[0066] In this embodiment, the second pipe section 310b, the first pipe section 310a, the connecting pipe 330, the third pipe section 320a, and the fourth pipe section 320b are connected in sequence, and the ends of the second pipe section 310b and the fourth pipe section 320b away from the connecting pipe 330 are both closed, thereby forming a closed enclosure air chamber 302. An air valve 303 is provided on the first pipe section 310a of the first side pipe 310. The air valve 303 is used to inflate and deflate the enclosure air chamber 302, making it convenient to use and easy to store.

[0067] Those skilled in the art will understand that in other embodiments, the second pipe section 310b, the first pipe section 310a, the connecting pipe 330, the third pipe section 320a, and the fourth pipe section 320b may not be connected. Each of the five sections may have its own air chamber, and each of the five air chambers may be equipped with an air valve to separately control the filling and releasing of the five air chambers.

[0068] In this embodiment, the inflation tube 300 is made of TPU (Thermoplastic Polyurethane) or PVC (Polyvinyl Chloride). TPU and PVC materials have excellent cold resistance, maintaining good elasticity and flexibility in cold environments, and can accommodate higher air pressures. Furthermore, this solves the problem of the inflatable sled 100 easily cracking at low temperatures and makes it easy to fold and carry.

[0069] Therefore, in cold weather, the air tube 300 will not become brittle due to low temperature, maintaining good elasticity and toughness, and continuing to play a protective role; the air base 200 can also maintain its physical properties at low temperatures, ensuring the overall structural stability of the inflatable sled 100.

[0070] refer to Figure 1 , Figure 3 and Figure 7Each of the second tube section 310b, the first tube section 310a, the connecting tube 330, the third tube section 320a, and the fourth tube section 320b of the inflation tube 300 is equipped with a handle 301. Specifically, the handles 301 on the first tube section 310a and the third tube section 320a correspond one-to-one along the width direction Y of the inflation base 200, and the handles 301 on the second tube section 310b and the fourth tube section 320b also correspond one-to-one along the width direction Y of the inflation base 200. This allows users seated in the cabin 400 to simultaneously grasp the handles 301 on both sides, improving the safety of the inflatable sled 100.

[0071] like Figure 1 As shown, the first tube section 310a and the third tube section 320a are each provided with a handle 301, and the second tube section 310b and the fourth tube section 320b are each provided with two handles 301. That is, there are three sets of handles 301 on both sides of the cockpit 400 for three users to grip. Those skilled in the art will understand that in other embodiments, the number of handles 301 can be set according to the volume of the cockpit 400. For example, if the cockpit 400 can accommodate four people, then correspondingly, four sets of handles 301 can be provided.

[0072] like Figure 7 As shown, the handle 301 located on the connecting tube 330 allows the user to drag the inflatable sled 100 to move it when needed. For example, when the inflatable sled 100 needs to be moved short distances, such as from the parking area to the start of a snow slope, or when the inflatable sled 100 is stuck in the snow and needs to be pulled out, the user can conveniently pull the inflatable sled 100 manually using the handle 301 on the connecting tube 330, saving energy and providing better directional control.

[0073] However, those skilled in the art will understand that this embodiment does not limit the function of each handle 301. For example, the handle 301 on the connecting tube 330 can also serve as a safety handle. That is, the user inside the cabin 400 can not only grasp the handles 301 on the first side tube 310 and the second side tube 320, but also grasp the handle 301 on the connecting tube 330 when needed to prevent the user from sliding inside the cabin 400, thereby improving the safety of the inflatable sled 100. Similarly, the handles 301 on the first side tube 310 and the second side tube 320 can also serve as drag handles. That is, the user can not only drag the inflatable sled 100 to move its position using the handles 301 on the connecting tube 330, but also directly drag it to move its position using the handles 301 on the first side tube 310 and the second side tube 320.

[0074] The handle 301 described in this embodiment is made of soft material, specifically nylon. Those skilled in the art will understand that in other embodiments, the handle 301 may also be made of rubber, plastic, or other materials.

[0075] In this embodiment, when the user pulls, the distance between the highest point of the handle 301 and the inflation tube 300 can be 2cm to 40cm, for example, it can be 2cm, 10cm, 20cm, 30cm, 40cm, etc.

[0076] It is understood that the handle 301 on the connecting tube 330 in this embodiment can be integrated with the drag ring 700 on the second end face 201b of the filament body 201 of the inflatable base 200. For example, a ring structure can be directly extended from the end of the handle 301 so that it can be both gripped and dragged.

[0077] Furthermore, the handle 301 described above in this embodiment can be used in conjunction with the anti-slip pad 401 inside the cockpit 400.

[0078] refer to Figure 3 and Figure 5 The aforementioned inflatable base 200 and inflatable tube 300 are connected by a connecting strip 600.

[0079] This embodiment has two connecting strips 600, namely an inner connecting strip 610 and an outer connecting strip 620. Both the inner connecting strip 610 and the outer connecting strip 620 are rectangular in shape and are located between the inflation tube 300 and the inflation base 200. The inner connecting strip 610 is located on one side inside the cabin 400, and the outer connecting strip 620 is located on one side outside the cabin 400. In other words, the inner connecting strip 610 and the outer connecting strip 620 are arranged at intervals in the radial direction of the tubular inflation tube 300.

[0080] The inner connecting strip 610 connects the inflation tube 300 and the first end face 201a of the inflation base 200. Specifically, the inner connecting strip 610 includes a first inner connecting strip 611, a second inner connecting strip (not shown in the figure), and a third inner connecting strip 612 connected in sequence. The first inner connecting strip 611 connects the first side tube 310 (including the first tube portion 310a and the second tube portion 310b) and the inflation base 200; the second inner connecting strip connects the connecting tube 330 and the inflation base 200; and the third inner connecting strip 612 connects the second side tube 320 (including the third tube portion 320a and the fourth tube portion 320b) and the inflation base 200.

[0081] In this embodiment, the inner connecting strip 610 is a single, elongated, flexible component made of TPU or PVC. The first inner connecting strip 611, the second inner connecting strip, and the third inner connecting strip 612 are three parts used to connect different positions of the inflatable base 200, that is, the inner connecting strip 610 surrounds the inflation tube 300 to connect the inflatable base 200 and the inflation tube 300. However, those skilled in the art will understand that in other embodiments, the inner connecting strip 610 can be divided into multiple segments, such as three segments, to respectively connect the first side tube 310 and the inflatable base 200, the connecting tube 330 and the inflatable base 200, and the second side tube 320 and the inflatable base 200.

[0082] Furthermore, the first inner connecting strip 611, the second inner connecting strip, and the third inner connecting strip 612 of the inner connecting strip 610 all include a first connecting surface 613. A portion of the first connecting surface 613 is high-frequency welded or bonded to the inflation tube 300, and another portion is high-frequency welded or bonded to the first end face 201a of the wire drawing material body 201 of the inflation base 200. Since the inflation tube 300 and the inflation base 200 are connected through the same surface, and since the inner connecting strip 610 is a flexible component, it can be understood that, without being subjected to external forces (such as collisions, wind, etc.), the inner connecting strip 610 is in a flexible state. Figure 5 The air inflator 300 may be V-shaped or folded, as shown. Under the influence of external forces, the air inflator 300 may move outward or inward relative to the cabin 400. If the air inflator 300 moves outward relative to the cabin 400, the inner connecting strip 610 will be stretched into a sheet shape. If the air inflator 300 moves inward relative to the cabin 400, the inner connecting strip 610 will be folded.

[0083] Accordingly, such as Figure 3 and Figure 5 As shown, the outer connecting strip 620 connects the inflation tube 300 and the side wall 203 of the inflation base 200. Specifically, the outer connecting strip 620 includes a first outer connecting strip 621, a second outer connecting strip (not shown in the figure), and a third outer connecting strip 622 connected in sequence. The first outer connecting strip 621 connects the first side tube 310 (including the first tube portion 310a and the second tube portion 310b) and the inflation base 200; the second outer connecting strip connects the connecting tube 330 and the inflation base 200; and the third outer connecting strip 622 connects the second side tube 320 (including the third tube portion 320a and the fourth tube portion 320b) and the inflation base 200.

[0084] In this embodiment, the outer connecting strip 620 is a single, elongated, flexible component made of TPU or PVC. The first outer connecting strip 621, the second outer connecting strip (not shown in the figure), and the third outer connecting strip 622 are three parts used to connect different positions of the inflatable base 200. That is, the outer connecting strip 620 surrounds the inflation tube 300 to connect the inflatable base 200 and the inflation tube 300. However, those skilled in the art will understand that in other embodiments, the outer connecting strip 620 can be divided into multiple segments, such as three segments, to respectively connect the first side tube 310 and the inflatable base 200, the connecting tube 330 and the inflatable base 200, and the second side tube 320 and the inflatable base 200.

[0085] Furthermore, the first outer connecting strip 621, the second outer connecting strip (not shown in the figure), and the third outer connecting strip 622 of the outer connecting strip 620 all include a second connecting surface 623. A portion of the second connecting surface 623 is high-frequency welded or bonded to the inflation tube 300, and another portion is high-frequency welded or bonded to the side wall 203 of the inflation base 200 (i.e., the reinforcing piece 230b mentioned above). Similarly, since the inflation tube 300 and the inflation base 200 are connected through the same surface, and since the outer connecting strip 620 is a flexible component, it can be understood that, without being subjected to external forces (such as collisions, wind, etc.), the outer connecting strip 620 forms... Figure 5 The air tube 300 may be in a V-shape or folded shape as shown. Under the action of some external forces, the air tube 300 may move outward or inward relative to the cabin 400. If the air tube 300 moves outward relative to the cabin 400, the outer connecting strip 620 will be folded. If the air tube 300 moves inward relative to the cabin 400, the outer connecting strip 620 will be stretched into a sheet shape.

[0086] Those skilled in the art will understand that in other embodiments, only one connecting strip 600 may be provided, namely either the inner connecting strip 610 or the outer connecting strip 620, depending on the usage requirements.

[0087] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
