TECHNICAL FIELD

[0001] The utility model relates to the field of inflatable products, in particular to a vehicle inflatable product. BACKGROUND

[0002] The vehicle inflatable cushion is a portable inflatable cushion specially designed for a vehicle, which can be placed in a rear seat or a trunk to provide comfortable rest during travel. However, in the prior art, due to the need for structural design, the interior of the vehicle often has uneven conditions, which limits the use range of the inflatable cushion when used in the vehicle. In order to adapt to the flat space in the vehicle, the existing inflatable cushion is often designed to have a very narrow application range, which limits the practicality and comfort of the inflatable cushion and affects the user's experience. SUMMARY

[0003] The utility model aims at solving the problem that the vehicle inflatable cushion on the market has a very narrow application range, low practicality and comfort, and is not conducive to the comfortable experience of the user. The utility model provides a vehicle inflatable product and a vehicle, which can expand the use range of the inflatable cushion in the vehicle and improve the comfort and practicality.

[0004] To solve the above technical problems, the embodiment of the utility model discloses a vehicle inflatable product, which comprises: a first support structure arranged in the gap of the internal structure of the vehicle; and an inflatable structure arranged above the first support structure and configured to be supported by the first support structure and a part of the internal structure of the vehicle, so that the inflatable structure is arranged horizontally or inclined.

[0005] By setting the height of the top of the first support structure to be similar to the height of the environment inside the vehicle around the first support structure, the inflatable structure is arranged horizontally or inclined when placed on the first support structure and a part of the internal structure of the vehicle (such as the backrest of the rear seat and the bottom of the trunk). Therefore, the first support structure of the embodiment of the utility model can fill the uneven places in the vehicle (such as the gap between the front seat and the rear seat).

[0006] Further, when using the inflatable structure in the vehicle, the user can expand the use area of the inflatable structure to the first support structure, expand the use range of the inflatable structure in the vehicle, expand the rest space of the user using the inflatable structure in the vehicle, improve the comfort and practicality of the inflatable structure, and improve the user's experience.

[0010] Preferably, the filler is a sponge pad, the sponge pad comprises: a first end portion, a part of the first end portion extends to the first portion along a length direction, another part of the first end portion extends to a position close to the narrowing portion along the length direction; a second end portion, a part of the second end portion extends to a position close to the narrowing portion along the length direction, another part of the second end portion extends to the tail portion along the length direction; and a middle portion located at the narrowing portion, the middle portion is located between the first end portion and the second end portion along the length direction.

[0011] Preferably, the first end portion of the sponge pad and the second end portion of the sponge pad are both provided with side openings extending along a width direction.

[0012] By using the above technical solution, the side openings of the sponge pad can reduce the weight of the sponge pad, improve the portability and practicability of the inflatable structure, and the middle portion of the sponge pad is not provided with side openings, which can enhance the supportability of the narrowing portion of the inflatable structure to the human body.

[0013] Preferably, the inflatable structure further comprises a first air valve arranged in the first side panel, the first upper panel or the first lower panel and in communication with the first chamber.

[0014] Preferably, the first support structure comprises: a second upper panel in contact with the first lower panel at the first portion; a second lower panel arranged opposite to the second upper panel; a second side panel connected to the second upper panel and the second lower panel; a second chamber defined by the second upper panel, the second side panel and the second lower panel; and a tensioning member located in the second chamber.

[0015] Preferably, the tensioning member includes a first side and a second side disposed opposite to each other along the height direction; the first side of the tensioning member is connected to the second upper piece, and the second side of the tensioning member is connected to the second lower piece.

[0056] 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.

[0057] Figures 1-2C This application illustrates a vehicle inflation product 100 provided in a first exemplary embodiment.

[0058] like Figure 1 As shown, the inflatable vehicle product 100 includes a first support structure 110 and an inflatable structure 120. Both the first support structure 110 and the inflatable structure 120 are in an inflatable state. The first support structure 110 supports the inflatable structure 120 and is used to fill uneven areas inside the vehicle (e.g., the gap between the front and rear seats) so that the inflatable structure 120 extends in the direction of extension (i.e., the length direction, such as...). Figure 1 (As shown in the X direction) Parallel to the horizontal plane, that is, the inflatable structure 120 is in a nearly horizontal state, so that the user can lie flat on the inflatable structure 120.

[0059] For example, the vehicle inflatable product 100 of this application embodiment is applied to a vehicle, which has an internal structure including a first seat (e.g., a first-row seat, referred to as the front seat 210), a second seat (e.g., a second-row seat, referred to as the rear seat 220), a trunk floor 230, a vehicle armrest 240, and a backrest.

[0060] However, this application does not limit the first seat and the second seat, as long as the second seat is located behind the first seat along the length direction X. For example, in other embodiments, the first seat can also be a second-row seat, and correspondingly, the second seat can be a third-row seat. In other embodiments, the backrest of the second seat can also be laid flat. For ease of explanation, the following description uses the first seat as the front seat 210 and the second seat as the rear seat 220 as an example.

[0061] Along the length direction of the vehicle (e.g.) Figure 1 (As shown in the X direction), the front seats 210 and the rear seats 220 are spaced apart. Both the front seats 210 and the rear seats 220 are connected to backrests 250, and the backrests 250 of the rear seats can be laid flat forward. The trunk floor 230 is located behind the rear seats 220, and the vehicle armrest 240 is located between the adjacent front seats 210 (one front seat 210 is shown in the figure).

[0062] It is understood that the application scenarios of the vehicle inflatable product 100 in this application embodiment are not specifically limited, as long as they can be used to improve the practicality and comfort of the inflatable structure 120 to enhance the user experience. For example, it can also be used in outdoor or indoor scenarios with limited flat space. For ease of understanding, the following description uses the vehicle inflatable product 100 of this application embodiment applied to the above-mentioned vehicle as an example.

[0063] Continue to refer to Figure 1 Along the length direction X, the first support structure 110 is disposed between the front seat 210 and the rear seat 220. When the backrest 250 of the rear seat is laid flat, the inflatable structure 120 is placed on the first support structure 110, the backrest 250 of the rear seat and the bottom of the trunk 230.

[0064] Specifically, such as Figure 1 As shown, along the length direction X, there is a gap 260 between the front seat 210 and the rear seat 220, and the first support structure 110 along the height direction (e.g.) Figure 1 Extending in the Z direction and located within the gap 260, the inflatable structure 120 includes a first part 120a, a second part 120b, a narrowing part 120c, and a tail part 120d (as shown in the Z direction). Figure 1 As shown in the dashed box, the first part 120a, the second part 120b, the narrowing part 120c, and the rear part 120d are arranged sequentially along the length direction X of the vehicle. That is, along the height direction Z, the first part 120a is placed above the first support structure 110 and supported by the first support structure 110, the second part 120b is placed above the backrest 250 of the rear seat 220 and supported by the backrest 250 of the rear seat 220, and the narrowing part 120c and the rear part 120d are placed above the trunk floor 230 and supported by the trunk floor 230.

[0065] The first support structure 110 in this embodiment can serve a "filling" function. This is achieved by setting the height of the top of the first support structure 110 to be similar to the height of the surrounding vehicle interior environment. For example, in this embodiment, the height of the first support structure 110 is set to be no lower than the height of the rear seat backrest 250 when it is laid flat. That is, when the inflatable structure 120 is placed on the first support structure 110, the rear seat backrest 250, and the trunk floor 230, the height of the first part 120a (e.g., ...) is... Figure 1 The height of H1 (as shown) is equal to the height of the second part 120b (as shown). Figure 1 (As shown in the middle H2 height), the inflatable structure 120 is set almost horizontally; or, as Figure 5 As shown, the height of the first part 120a (e.g.) Figure 5 The height of H3 (as shown) is greater than the height of the second part 120b (as shown). Figure 5 (As shown at height H4), the inflatable structure is tilted at 120 degrees.

[0066] Therefore, the first support structure 110 of this embodiment can fill uneven areas inside the vehicle (such as the gap 260 between the front seat 210 and the rear seat 220). Furthermore, when the user uses the inflatable structure 120 inside the vehicle, the usable area of ​​the inflatable structure 120 can be expanded to the first support structure 110, increasing the usable range of the inflatable structure 120 inside the vehicle, expanding the resting space for the user, improving the comfort and practicality of the inflatable structure 120, and enhancing the user experience.

[0067] The following will be combined with the appendix Figures 2A-2C This application provides a detailed description of the structure and working principle of the first support structure 110 and the inflatable structure 120 provided in the embodiments of this application.

[0068] refer to Figure 2A , Figure 2B and Figure 2C The inflatable structure 120 also includes a first upper piece 121, a first lower piece 122, and a first side piece 123. The first side piece 123 is circumferentially aligned with the inflatable structure (e.g., along the circumference of the inflatable structure). Figure 2A Extending in the direction shown in R1. Along the height direction (as shown in the middle R1 direction). Figure 2A (As shown in the Z-direction), the first lower sheet 122 is disposed opposite to the first upper sheet 121, and the first side sheet 123 is connected to the first upper sheet 121 and the first lower sheet 122. Exemplarily, both the first upper sheet 121 and the first lower sheet 122 are flexible sheet-like TPU / PVC polymer composite materials, and the first side sheet 123 is a continuous flexible sheet-like TPU / PVC polymer composite material forming a ring, extending along the width direction (e.g., ...). Figure 2A As shown in the Y direction, both the first upper piece 121 and the first lower piece 122 narrow at the narrowing portion 120c along the width direction Y, and the annular structure formed by the first side piece 123 also narrows at the narrowing portion 120c along the width direction Y, in order to make way for the position of the vehicle tire (not shown in the figure).

[0069] Specifically, such as Figure 2A and Figure 2C As shown, the first side piece 123 also includes a top end 123a and a bottom end 123b. Along the height direction Z, the first upper piece 121 is sealed to the top end 123a of the first side piece 123, and the upper end (i.e., the top end 123a) of the first side piece 123 is connected to the outer periphery of the bottom surface of the first upper piece 121. The first lower piece 122 is sealed to the bottom end 123b of the first side piece 123, and the lower end (i.e., the bottom end 123b) of the first side piece 123 is connected to the outer periphery of the top surface of the first lower piece 122. Thus, the first upper piece 121, the first lower piece 122, and the first side piece 123 of the inflatable structure 120 together define the first chamber 124.

[0070] In other embodiments, the top end 123a of the first side piece 123 may not be covered by the outer edge of the first upper piece 121, that is, the top end 123a of the first side piece 123 is located at the outer edge of the top surface of the first upper piece 121, and the outer edge of the first upper piece 121 is connected to the inner side of the top end 123a of the first side piece 123; similarly, the bottom end 123b of the first side piece 123 may not be covered by the outer edge of the first lower piece 122, that is, the bottom end 123b of the first side piece 123 is located at the outer edge of the bottom surface of the first lower piece 122, and the outer edge of the first lower piece 122 is connected to the inner side of the bottom end 123b of the first side piece 123.

[0071] Accordingly, refer to Figure 2B and Figure 2C and combined Figure 1 For ease of understanding, such as Figure 2B As shown, the first part 120a, the second part 120b, the narrowing part 120c, and the tail part 120d of the inflatable structure 120 are shown in dashed boxes. Since the inflatable structure 120 of this embodiment is horizontally arranged, that is, the height of the first support structure 110 is equal to the height of the backrest 250 of the rear seat after it is laid flat, the first lower piece 122 contacts the first support structure 110 at the first part 120a and is supported by the first support structure 110. The first lower piece 122 contacts the backrest 250 of the rear seat at the second part 120b and is supported by the backrest 250 of the rear seat. The first lower piece 122 contacts the bottom of the trunk 230 at the narrowing part 120c and the tail part 120d and is supported by the bottom of the trunk 230.

[0072] Continue to refer to Figure 2C and combined Figure 2B The inflatable structure 120 in this embodiment also includes a filling portion located within the first chamber 124 to improve the comfort of the inflatable structure 120 and enhance the user experience. Exemplarily, the filling portion in this embodiment is a sponge pad 125; however, it is not limited thereto. This embodiment does not limit the material of the filling portion of the inflatable structure, as long as it can improve the comfort of the inflatable structure 120, such as a silicone pad. The following description uses a sponge pad as an example of the filling portion in this embodiment for ease of understanding.

[0073] Specifically, such as Figure 2B and Figure 2C As shown, the sponge pad 125 is located within the first chamber 124 and is connected to the first upper piece 121 and the first lower piece 122 respectively (e.g., by heat pressing) to fix it within the first chamber 124. Exemplarily, along the width direction Y, the sponge pad 125 decreases in size along the width direction Y at the narrowing portion 120c, i.e., it narrows at the narrowing portion 120c.

[0074] The sponge pad 125 includes a first end 125a, a second end 125b, and a middle portion 125c. Correspondingly, along the length direction (e.g., ...) Figure 2C (As shown in the X direction), a portion of the first end 125a of the sponge pad 125 extends to the positions of the first portion 120a and the second portion 120b of the inflatable structure 120, and another portion of the first end 125a of the sponge pad 125 extends to a position near the narrowing portion 120c of the inflatable structure 120. A portion of the second end 125b extends to a position near the narrowing portion 120c of the inflatable structure 120, and another portion of the second end 125b extends to the position of the tail portion 120d of the inflatable structure 120. The middle portion 125c is located in the narrowing portion 120c of the inflatable structure 120 and is situated between the first end 125a and the second end 125b.

[0075] Therefore, when the inflatable structure 120 is placed inside the vehicle and is in an inflatable state, the sponge pad 125 of this embodiment extends along the length direction X within the first chamber 124 to form a sponge air cushion. At this time, the top surface of the inflatable structure 120 (i.e., the first upper piece 121) is used for the user to rest, and the bottom surface of the inflatable structure 120 (i.e., the first lower piece 122) presses against the first support structure 110, the backrest 250 of the rear seat, and the bottom of the trunk 230. The front side of the inflatable structure 120 (i.e., the front side wall 123c of the first side piece 123 near the front of the vehicle) abuts against the backrest 251 of the front seat, and the two long sides of the inflatable structure 120 (i.e., the two side walls 123d of the first side piece 123 extending along the length direction X and arranged opposite each other) abut against the rear side wall of the vehicle interior (e.g., the two side doors, not shown in the figure) and the side wall of the trunk (not shown in the figure), so that the inflatable structure 120 has good stability during use and is not easy to shake. In addition, through the support of the first support structure 110, the inflatable structure 120 can also be kept flat as a whole, improving the user experience.

[0076] Exemplarily, the inflation structure 120 of this application embodiment also includes a first air valve 126, which communicates with the first chamber 124, so that the inflation structure 120 can be inflated or deflated through the first air valve 126. Furthermore, since the inflation structure 120 is limited by the vehicle's interior space during use, the top surface, bottom surface, front side, and both long sides of the inflation structure 120 are not convenient for installing the first air valve 126 for inflation / deflation operations. However, since the vehicle's trunk can be opened, there is still operational space on the rear side of the inflation structure 120 for the first air valve 126 to perform inflation / deflation operations. In this application embodiment, the first air valve 126 is located on the rear side wall 123e of the first side piece 123 near the rear of the vehicle to facilitate inflation or deflation of the inflation structure 120. However, this application embodiment does not specifically limit the location of the first air valve 126, as long as it can be used for inflation or deflation of the inflation structure 120. In other embodiments, the location of the first air valve 126 can be selected according to the actual vehicle interior space, such as the top surface (e.g., the first upper piece 121), bottom surface (e.g., the first lower piece 122), front side (front side wall 123c of the first side piece 123), or both long sides (both side walls 123d of the first side piece 123), etc. of the inflation structure 120.

[0077] In addition, such as Figure 2C As shown, the sponge pad 125 in this embodiment of the application also includes side openings 125d. The side openings 125d are disposed inside the sponge pad 125 and extend along the width direction Y to reduce weight and improve the portability and practicality of the inflatable structure 120. For example, the sponge pad 125 has eleven side openings 125d, which are respectively spaced along the length direction X at the first end 125a and the second end 125b of the sponge pad 125. That is, the middle portion 125c of the sponge pad 125 does not have side openings 125d, to enhance the support of the narrowed portion 120c of the inflatable structure 120 for the human body. However, this application embodiment does not specifically limit the number and position distribution of the side openings 125d of the sponge pad 125. In other embodiments, the middle part 125c of the sponge pad 125 may also be provided with side openings 125d, and the number of side openings 125d may also include one, two, three, four, five, six, seven, eight, nine, ten, twelve, thirteen or more.

[0078] Continue to refer to Figure 2C and combined Figure 2B The first support structure 110 in this embodiment includes a second upper piece 111, a second lower piece 112, and a second side piece 113. The second side piece 113 is circumferentially aligned with the first support structure 110 (e.g., along the circumference of the first support structure 110). Figure 2B and Figure 2C Extending in the direction shown in R2. Along the height direction (as shown in the middle R2 direction). Figure 2B andFigure 2C (As shown in the Z-direction), the second lower piece 112 is disposed opposite to the second upper piece 111, and the second side piece 113 is connected to the second upper piece 111 and the second lower piece 112. Exemplarily, both the second upper piece 111 and the second lower piece 112 are flexible sheet-like TPU / PVC polymer composite materials, and the second side piece 113 is a continuous flexible sheet-like TPU / PVC polymer composite material forming a ring. Furthermore, along the width direction Y, one side of the first support structure 110 extends to the left side door (not shown in the figure), and the other side extends to the right side door (not shown in the figure).

[0079] Specifically, such as Figure 2B and 2C As shown, the second side piece 113 also includes a top end 113a and a bottom end 113b. Along the height direction Z, the second upper piece 111 is sealed to the top end 113a of the second side piece 113, and the upper end (i.e., the top end 113a) of the second side piece 113 is connected to the outer periphery of the bottom surface of the second upper piece 111. The second lower piece 112 is sealed to the bottom end 113b of the second side piece 113, and the lower end (i.e., the bottom end 113b) of the second side piece 113 is connected to the outer periphery of the top surface of the second lower piece 112. Thus, the second upper piece 111, the second lower piece 112, and the second side piece 113 of the first support structure 110 together define the second chamber 114.

[0080] In other embodiments, the top end 113a of the second side piece 113 may not be covered by the outer edge of the second upper piece 111, that is, the top end 113a of the second side piece 113 is located at the outer edge of the top surface of the second upper piece 111, and the outer edge of the second upper piece 111 is connected to the inner side of the top end 113a of the second side piece 113; similarly, the bottom end 113b of the second side piece 113 may not be covered by the outer edge of the second lower piece 112, that is, the bottom end 113b of the second side piece 113 is located at the outer edge of the bottom surface of the second lower piece 112, and the outer edge of the second lower piece 112 is connected to the inner side of the bottom end 113b of the second side piece 113.

[0081] refer to Figure 2C and combined Figure 2B and Figure 1 The first support structure 110 in this embodiment of the application also includes a tensioning member 115, which is located in the second chamber 114. Along the height direction Z, the tensioning member 115 is connected to the second upper piece 111 and the second lower piece 112 respectively. When the first support structure 110 is in an inflated state, the tensioning member 115 is tensioned and provides a pulling force towards the second upper piece 111 and the second lower piece 112 towards the second chamber 114 to limit the deformation of the first support structure 110, so that the first support structure 110 can maintain a preset shape and height after being inflated, for example, maintaining a column shape and having a height equal to the height of the backrest 250 of the rear seat after it is flattened.

[0082] Exemplarily, the tensioning member 115 in this embodiment is a sheet-like member, including a first side 115a and a second side 115b disposed opposite each other along the height direction Z. Along the height direction Z, the first side 115a of the tensioning member 115 is connected to the bottom surface of the second upper sheet 111 by high-frequency welding, hot-melt, adhesive bonding, or other connection methods, and the second side 115b of the tensioning member 115 is connected to the top surface of the second lower sheet 112 by high-frequency welding, hot-melt, adhesive bonding, or other connection methods. However, this embodiment does not specifically limit the structure of the tensioning member 115; the tensioning member 115 has different structures in different embodiments. For example, in other embodiments, the tensioning member 115 can also be a linear member.

[0083] Exemplarily, in other embodiments, the tensioning member 115 may also be horizontally arranged, and multiple horizontal tensioning members 115 are provided (e.g., two, three, four, five, or more). Each horizontal tensioning member 115 is connected to the second side plate 113, and each horizontal tensioning member 115 includes a first side 115a and a second side 115b arranged horizontally opposite each other. The second side plate 113 includes a front side wall 113c and a rear side wall (not shown in the figure). For example, one side (e.g., the first side 115a) of each horizontal tensioning member 115 is connected to the front side wall 113c of the second side plate 113, and the opposite side (e.g., the second side 115b) is connected to the rear side wall of the second side plate 113. Thus, when the first support structure 110 is in an inflated state, each horizontal tensioning member 115, after being tensioned, can provide tension towards the second chamber 114 on the front side wall 113c and the rear side wall of the second side plate 113, respectively, to limit the deformation of the first support structure 110.

[0084] Exemplarily, the first support structure 110 in this embodiment further includes a second air valve 116, which communicates with the second chamber 114, allowing the first support structure 110 to be inflated or deflated via the second air valve 116. Furthermore, since the first support structure 110 is limited by the vehicle interior space during use, the bottom surface of the first support structure 110 (i.e., the second lower piece 112) is not convenient for mounting the second air valve 116 for inflation / deflation operations. However, the side surface of the first support structure 110 (i.e., the second side piece 113) still provides operating space for the second air valve 116 to perform inflation / deflation operations. In this embodiment, the second air valve 116 is located on the second side piece 113 to facilitate the inflation or deflation of the first support structure 110. However, this embodiment does not specifically limit the location of the first support structure 110, as long as it can be used for inflation or deflation of the first support structure 110. In other embodiments, the location of the second air valve 116 can be selected according to the actual interior space, such as the top surface of the first support structure 110 (i.e., the second upper piece 111).

[0085] It is understood that the embodiments of this application do not specifically limit the components of the inflatable structure 120, as long as it can define the first chamber 124 and provide a filling part (such as the aforementioned sponge pad 125) within the first chamber 124 for the user to rest. For example, in other embodiments, unlike the first exemplary embodiment, the inflatable structure 120 may not include the first side piece 123, that is, the inflatable structure 120 only includes the first upper piece 121 and the first lower piece 122. Specifically, along the height direction Z, the first lower piece 122 is disposed opposite to the first upper piece 121, and the first lower piece 122 is connected to the first upper piece 121, and together with the first upper piece 121, defines the first chamber 124, so that the filling part (such as the sponge pad 125) is located within the first chamber 124. Thus, the aforementioned first air valve 126 is disposed on the first upper piece 121, or the first air valve 126 is disposed on the first lower piece 122 and communicates with the first chamber 124.

[0086] Furthermore, the embodiments of this application do not specifically limit the structure of the first support structure 110 and the inflatable structure 120. For example, the first support structure 110 and the inflatable structure 120 can also be non-inflatable sponge pads.

[0087] It is understood that in this embodiment, the first support structure 110 does not need to be connected and fixed to the first lower piece 122 of the inflatable structure 120. Instead, the first support structure 110 and the inflatable structure 120 are inflated independently and then manually placed together, which is more convenient for the user. However, this embodiment does not limit the connection relationship between the first support structure 110 and the first lower piece 122 of the inflatable structure 120. For example, in other embodiments, the first support structure 110 can also be connected and fixed to the first lower piece 122 of the inflatable structure 120, or the first support structure 110 can also be integrally formed with the inflatable structure 120.

[0088] Figures 3A-3B This application illustrates a vehicle inflation product 100 provided in a second exemplary embodiment.

[0089] Unlike the first exemplary embodiment, the first support structure 110 in this application embodiment also includes a first recess 117.

[0090] Specifically, such as Figure 3A and Figure 3B As shown, in this embodiment of the application, the first recess 117 extends along the height direction Z, and the first recess 117 is used to match the first protrusion 241 of the vehicle armrest 240 (see...). Figure 1 This arrangement allows the first protrusion 241 of the vehicle armrest 240 to be located within the first recess 117 of the first support structure 110, further expanding the usable space of the inflatable structure 120 inside the vehicle. For example, as shown... Figure 3A and Figure 3B As shown, along the length direction X, the first recess 117 is provided on the front sidewall 113c of the second side piece 113. Correspondingly, the second upper piece 111 and the second lower piece 112 of the first support structure 110 are both narrowed in the length direction X at the first recess 117.

[0091] Furthermore, for ease of understanding, such as Figure 3BAs shown, the first part 120a, the second part 120b, the narrowing part 120c, and the tail part 120d of the inflatable structure 120 are shown in dashed boxes. In this embodiment, the dimensions of the first upper piece 121 and the first lower piece 122 of the inflatable structure 120 decrease along the width direction Y at the narrowing part 120c and the tail part 120d, and the annular structure formed by the first side pieces 123 also decreases in size at the narrowing part 120c and the tail part 120d, that is, the inflatable structure 120 narrows at the narrowing part 120c and the tail part 120d. However, this application embodiment does not specifically limit the shape of the first upper piece 121, the first lower piece 122, and the first side piece 123 of the inflatable structure 120. In other embodiments, the shape of the first upper piece 121, the first lower piece 122, and the first side piece 123 can also be selected according to the actual vehicle interior space. For example, the dimensions of the first upper piece 121, the first lower piece 122, and the first side piece 123 are reduced only at the narrowing portion 120c along the width direction Y, while the dimensions at the tail portion 120d along the width direction Y remain unchanged.

[0092] Figure 4 This application illustrates a vehicle inflation product 100 provided in a third exemplary embodiment.

[0093] Unlike the first exemplary embodiment, the inflatable structure 120 of this application embodiment is connected to the first support structure 110 via a connector (e.g., a first connector and a second connector).

[0094] Specifically, such as Figure 4 As shown, in this embodiment of the inflatable structure 120, the first lower piece 122 has a first mounting hole 122a, in which a first connector 122b is installed and communicates with the first chamber 124. The second upper piece 111 of the first support structure 110 has a second mounting hole 111a, in which a second connector 111b is installed and communicates with the second chamber 114. The first connector 122b and the second connector 111b are detachably and sealingly connected to connect the inflatable structure 120 to the first support structure 110 and to communicate between the first chamber 124 and the second chamber 114. In other exemplary embodiments, the first connector 122b and the second connector 111b may also be non-detachably and sealingly connected, meaning the first support structure 110 and the inflatable structure 120 are interconnected and inseparable via the first connector 122b and the second connector 111b.

[0095] By way of example, the first connector 122b and the second connector 111b in this application embodiment are both cylindrical connectors extending along the height direction Z and have through holes. The inner diameter of the through hole of the first connector 122b is larger than the outer diameter of the second connector 111b, so that the second connector 111b can be inserted into the through hole of the first connector 122b along the height direction Z, connecting the first chamber 124 and the second chamber 114. A sealing element (such as a sealing ring provided on the outside of the second connector 111b, not shown in the figure) is provided between the first connector 122b and the second connector 111b to make the first connector 122b and the second connector 111b sealed and connected.

[0096] Therefore, on the one hand, the embodiments of this application achieve a modular design by providing a first connector 122b in the first chamber 124 and a second connector 111b in the second chamber 114. That is, the first connector 122b and the inflation structure 120 are one module, and the first connector 122b can be used alone as the inflation / deflation port of the first chamber 124. The second connector 111b and the first support structure 110 are another module, and the second connector 111b can be used alone as the inflation / deflation port of the second chamber 114. When any module is damaged, only the corresponding module needs to be replaced, which can reduce the probability of scrapping the entire vehicle inflation product 100 and has significant benefits in terms of environmental protection and production cost control.

[0097] On the other hand, when the first chamber 124 of this embodiment is connected to the second chamber 114 via the first connector 122b and the second connector 111b, the user only needs to perform one inflation / deflation operation to simultaneously inflate and deflate the two chambers (e.g., the first chamber 124 and the second chamber 114), which is simple and efficient. For example, the inflation structure 120 and the first support structure 110 can be simultaneously inflated and deflated using only the first air valve 126 of the inflation structure 120 described in the first exemplary embodiment, or the inflation structure 120 and the first support structure 110 can be simultaneously inflated and deflated using only the second air valve 116 of the first support structure 110 described in the first exemplary embodiment.

[0098] However, this application does not specifically limit the structure of the first connector 122b and the second connector 111b. The first connector 122b and the second connector 111b can have different structures in different embodiments. For example, in other embodiments, the first connector 122b and the second connector 111b can also be mutually compatible square cylindrical connectors. Furthermore, the first connector 122b can be connected to the fabric at the outer periphery of the first mounting hole 122a on the first lower piece 122 by means of high-frequency welding or hot pressing, and the second connector 111b can also be connected to the fabric at the outer periphery of the second mounting hole 111a on the second upper piece 111 by means of high-frequency welding or hot pressing.

[0099] Figure 5 This application illustrates a vehicle inflation product 100 provided in a fourth exemplary embodiment.

[0100] Unlike the first exemplary embodiment, the vehicle inflatable product 100 of this application embodiment also includes a second support structure 130, which is supported below the inflatable structure 120 to provide support for the inflatable structure 120 together with the first support structure 110.

[0101] Specifically, such as Figure 5 As shown, when the backrest 250 of the rear seat is laid flat until it contacts the rear seat 220 and cannot be laid down further (i.e., after the backrest 250 of the rear seat is fully laid down), it is not in a completely horizontal state. The height of the backrest 250 of the rear seat gradually decreases backward along the length direction X. When the inflatable structure 120 is placed on the first support structure 110, the backrest 250 of the rear seat, and the trunk floor 230, the inflatable structure 120 of this embodiment is tilted. That is, the height of the first lower piece 122 of the inflatable structure 120 at the first part 120a is greater than the height of the first lower piece 122 at the second part 120b. In other words, the height of the first part 120a of the inflatable structure 120 is greater than the height of the first lower piece 122 at the second part 120b. Figure 5 The height of H3 (as shown) is greater than the height of the second part 120b (as shown). Figure 5 (As shown at height H4). At this time, the connection between the backrest 250 of the rear seat and the bottom of the trunk 230 has a second recess 280, and the first lower piece 122 of the inflatable structure 120, together with the backrest 250 of the rear seat and the bottom of the trunk 230, defines a gap space 270.

[0102] Exemplarily, the second support structure 130 contacts and supports the first lower piece 122 of the inflatable structure 120, and the second support structure 130 has a second protrusion 131 that matches the second recess 280, so that the second support structure 130 can be accommodated within the gap space 270, and the second protrusion 131 and the second recess 280 are in a corrugated fit. Along the height direction (e.g. Figure 5 As shown in the Z-direction), a portion 130a of the second support structure 130 (as shown in the Z-direction) Figure 5 As shown, the other part 130b of the second support structure 130 (as shown) is located between the first lower piece 122 at the second part 120b and the backrest 250 of the rear seat, and is located between the first lower piece 122 at the second part 120b and the backrest 250 of the rear seat. Figure 5As shown, the first lower piece 122 is located between the narrowed portion 120c and the trunk floor 230 to provide support to the second portion 120b and the narrowed portion 120c of the inflatable structure 120, preventing the second portion 120b and the narrowed portion 120c of the inflatable structure 120 from sinking downwards due to the presence of the gap space 270 when the user lies flat on the inflatable structure 120, thereby enhancing the support of the inflatable structure 120 for the human body.

[0103] It is understood that in this embodiment, the second support structure 130 does not need to be connected and fixed to the first lower piece 122 of the inflatable structure 120. Instead, the second support structure 130 and the inflatable structure 120 are independently set and manually placed together, making it more convenient for the user. However, this embodiment does not limit the connection relationship between the second support structure 130 and the first lower piece 122 of the inflatable structure 120. For example, in other embodiments, the second support structure 130 can also be connected and fixed to the first lower piece 122 of the inflatable structure 120, or the second support structure 130 can also be integrally formed with the inflatable structure 120.

[0104] Furthermore, the embodiments of this application do not specifically limit the structure of the second support structure 130. For example, the second support structure 130 can be a non-inflatable sponge pad (e.g., one, two, three, four, five, or more sponges); or, the second support structure 130 can also be an inflatable air pad. Thus, the second support structure 130 can also be connected and fixed to the inflatable structure 120 through connecting joints (e.g., the first joint 122b and the second joint 111b described in the first exemplary embodiment), so that the independent air chambers of the second support structure 130 and the inflatable structure 120 (e.g., the inflatable chamber of the second support structure 130 and the first chamber 124 of the inflatable structure 120) are interconnected, that is, the inflatable chamber of the second support structure 130 and the first chamber 124 of the inflatable structure 120 are interconnected.

[0105] Furthermore, this application embodiment does not specifically limit the shape and number of the second support structure 130, such as Figure 5 As shown, in this embodiment of the application, the second part 120b and the narrowing part 120c of the inflatable structure 120 together with the backrest 250 of the rear seat and the bottom of the trunk 230 define a gap space 270 with a triangular cross section, and the cross section of the second support structure 130 is correspondingly triangular; however, it is not limited to this. In other embodiments, the cross section of the second support structure 130 may also be correspondingly arc-shaped and accommodated in the gap space 270 with an arc-shaped cross section.

[0106] In this embodiment of the application, there are no specific limitations on the surface covering materials of the second upper piece 111, the second lower piece 112, the second side piece 113 of the first support structure 110, the first upper piece 121, the first lower piece 122, the first side piece 123 of the inflatable structure 120, and the second support structure 130. For example, it can be the TPU / PVC polymer composite material mentioned above, but it is not limited to this. It can also be other composite upper piece materials containing fabric and with high strength.

[0107] This application does not impose specific limitations on the sealing connection method between the above-mentioned components. For example, the sealing connection can be achieved by high-frequency welding, adhesive bonding, or hot melting.

[0108] Thus, this application describes the structure of a vehicle inflatable product 100. These embodiments all enable the first support structure 110 of the vehicle inflatable product 100 to function as a support structure after inflation, supporting the inflation structure 120 and together forming the vehicle inflatable product 100. Compared with conventional vehicle inflatable structures currently on the market, the vehicle inflatable product 100 provided by the embodiments of this application has a wider range of applications inside automobiles, higher comfort, and greater practicality.

[0109] The exemplary embodiments disclosed in this application can be replaced, combined or modified in various ways. Without departing from the essence of this application, all such variations still belong to the concept of this application and fall within the protection scope defined by the claims of this application.

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.
