Description

Technical Field

[0001] This application relates to the field of mattresses, and more particularly to a vehicle-mounted mattress. Background Technology

[0002] A car mattress is generally a mattress placed inside a vehicle for rest. Its bottom conforms to the vehicle's interior structure, while its top forms a flat surface for users to lie down and relax. Unlike regular home mattresses, car mattresses are typically lighter and can be inflated and flattened when in use, and compressed, folded, or rolled up for storage when not in use, making them suitable for users to carry while driving.

[0003] Currently, most car mattresses have support structures at the front and rear that match the seats or trunk. For example, these might be a protruding structure integrated into the mattress's internal foam core, or a separate inflatable support pack. However, the adaptability of common car mattress support structures to the vehicle's interior structure is limited. In some vehicles, the rear seats and front seats have a slight height difference, creating a staggered structure. When a user lies down on the mattress, their lower back is usually positioned over this staggered structure, resulting in uneven pressure on the lower back and a less than ideal user experience. Utility Model Content

[0004] In order to better match the vehicle's interior structure and further improve the user experience, this application provides a vehicle mattress.

[0095] The following is in conjunction with the appendix Figure 1-10This application will be further described in detail below. For ease of understanding, in the following embodiments, "front" refers to a position relatively close to the front of the vehicle; "rear" refers to a position relatively close to the rear of the vehicle; "left" refers to a position relatively close to the driver's side; "right" refers to a position relatively close to the passenger's side; "up" refers to a position relatively close to the roof of the vehicle; and "down" refers to a position relatively close to the chassis of the vehicle. The first direction represents the length direction of the vehicle, i.e., the front-to-back direction of the vehicle; the second direction represents the width direction of the vehicle, i.e., the left-to-right direction of the vehicle; and the third direction represents the height direction of the vehicle, i.e., the vertical direction of the vehicle.

[0096] Reference Figure 1 The vehicle-mounted mattress includes a mattress body 100, a main support body 200, and an auxiliary support body 300, with the main support body 200 and auxiliary support body 300 located below the mattress body 100. Figure 2 When the car mattress is in use, the main support 200 and the auxiliary support 300 contact and match the vehicle's internal structure 400 and are supported by the vehicle's internal structure 400. The mattress body 100 is located on the main support 200 and the auxiliary support 300 and is supported by the main support 200 and the auxiliary support 300.

[0097] Reference Figure 2 Along the first direction, the vehicle interior structure 400, from front to back, includes a front seat 410, a rear seat 420, and a trunk floor 430. Specifically, when using the car mattress, the backrests of the front seats 410 are folded back, and the backrests of the rear seats 420 are folded forward. The area adjacent to the backrests of the front seats 410 and the rear seats 420 is an uneven, staggered area 440, which includes an upward-sloping area 441 and a downward-sloping area 442. Within the upward-sloping area 441, along the first direction, the height of the top surface of the headrest of the rear seat 420 gradually increases from front to back, meaning the height of the vehicle interior structure 400 within the upward-sloping area 441 gradually increases from front to back. Within the downward-sloping area 442, along the first direction, the height of the top surface of the backrest of the rear seats 420 gradually decreases from front to back, meaning the height of the vehicle interior structure 400 within the downward-sloping area 442 gradually decreases from front to back. A portion of the auxiliary support 300 is located in the upper tilt zone 441 and matches the vehicle interior structure 400 within the upper tilt zone 441, while the remaining portion of the auxiliary support 300 is located in the lower tilt zone 442 and matches the vehicle interior structure 400 within the lower tilt zone 442. That is, along the first direction, the support height of the auxiliary support 300 matching the vehicle interior structure 400 within the upper tilt zone 441 gradually decreases from front to back, while the support height of the auxiliary support 300 matching the vehicle interior structure 400 within the lower tilt zone 442 gradually increases from front to back.

[0098] Continue to refer to Figure 2A main support 200 is placed on the front seat 410 and the rear seat 420, and an auxiliary support 300 is placed in the staggered area 440. That is, the main support 200 is arranged adjacent to the front of the auxiliary support 300 and adjacent to the rear of the auxiliary support 300. The main support 200 is used to match the vehicle interior structure 400 located outside the staggered area 440. The main support 200 in front of the auxiliary support 300 is supported by the front seat 410, and the main support 200 behind the auxiliary support 300 is jointly supported by the rear seat 420 and the trunk floor 430. The auxiliary support 300 is located in the staggered area 440 and is supported by the backrest and headrest of the rear seat 420. It should be noted that the auxiliary support 300 can also be supported by the front seat 410 in the staggered area 440, or it can be supported by both the front seat 410 and the rear seat 420 in the staggered area 440. The support received by the auxiliary support 300 varies depending on the positional relationship between the backrest of the front seat 410 and the rear seat 420. For example, in this embodiment, the backrest of the front seat 410 is first laid flat backward, and then the backrest of the rear seat 420 is laid flat forward, so that the headrest of the rear seat 420 is located above the backrest of the front seat 410; in other optional embodiments, the backrest of the rear seat 420 can also be laid flat forward first, and then the backrest of the front seat 410 can be laid flat backward, so that the headrest of the front seat 410 is located above the backrest of the rear seat 420, and so on. Furthermore, without limitation, the height of the vehicle interior structure 400 located within the staggered area 440 is greater than the height of the vehicle interior structure 400 located outside the staggered area 440, and correspondingly, the support height of the auxiliary support 300 is less than the support height of its adjacent main support 200.

[0099] Reference Figure 1Specifically, the mattress body 100 includes an outer wall 110 and a closed main cavity, which is defined within the outer wall 110. The main cavity of the mattress body 100 may contain a filling material (not shown). The filling material can be a block-shaped elastic material, a flocculent filling material, etc. For example, the filling material may be a whole piece of sponge, located in the main cavity of the mattress body 100 and in contact with the outer wall 110. Furthermore, the surface of the sponge can be fixed to the outer wall 110 by hot pressing or adhesive bonding. The main support 200 includes a first outer wall 210 and a closed first cavity, which is defined within the first outer wall 210. A first tensioning member (not shown) is provided within the first outer wall 210, and the first tensioning member is fixed to the first outer wall 210 by welding, forming a weld 211 on the first outer wall 210. The first tensioning member exerts a tensioning force on the outer wall 110 of the main body at weld 211, thereby causing the main support 200 to form a preset shape after inflation. In an alternative embodiment, the first tensioning member can also be fixedly connected to the first outer wall 210 by adhesive.

[0100] Reference Figure 3 Specifically, the auxiliary support 300 includes a second outer wall 310, which includes an upper piece 311 and a lower piece 312. The upper piece 311 and the lower piece 312 are arranged opposite each other, and the outer edges of the upper piece 311 and the lower piece 312 are fixedly connected to each other to jointly define the second chamber 320. Optionally, both the upper piece 311 and the lower piece 312 are airtight weldable sheets, and the outer edges of the upper piece 311 and the lower piece 312 are fixedly connected by welding; or, both the upper piece 311 and the lower piece 312 are airtight sheets, and the outer edges of the upper piece 311 and the lower piece 312 are fixedly connected by adhesive. Further, the auxiliary support 300 also includes a height limiting structure 330, which is distributed at preset intervals along the first direction. When gas is filled into the second chamber 320, the height limiting structure 330 restricts the distance between the upper piece 311 and the lower piece 312 so that the auxiliary support 300 forms a preset shape.

[0101] Continue to refer to Figure 3In an optional embodiment, the height-limiting structure 330 includes a seam line 331, which is a welded or adhesive line formed by welding or gluing the upper piece 311 and the lower piece 312 together. The seam line 331 extends along a second direction. Multiple seam lines 331 are provided, distributed at preset intervals along a first direction to divide the second chamber 320 of the auxiliary support 300 into multiple seam chambers 321. Furthermore, the multiple seam lines 331 are arranged parallel to each other, each seam line 331 extending along the second direction; correspondingly, the multiple seam chambers 321 are parallel to each other, and each seam chamber 321 extends along the second direction. When the auxiliary support 300 is inflated, multiple cylindrical seam chambers 321 arranged sequentially and parallel to each other are formed within the auxiliary support 300. The first and last seam chambers 321 in the first direction are defined by an upper piece 311 and a lower piece 312 located between the seam line 331 and the edge of the second outer wall 310. Each of the remaining seam chambers 321 is defined by an upper piece 311 and a lower piece 312 located between two adjacent seam lines 331. When the auxiliary support 300 is inflated, the diameter φ of the cylindrical seam chamber 321 is approximately equal to its support height h. When deflated, both the upper piece 311 and the lower piece 312 are flat sheets, and the distance between two adjacent seam lines 331 is equal to half the circumference of the cylindrical seam chamber 321 between the two seam lines 331 after inflation. Therefore, the distribution distance of the seam lines 331 in the deflated state can be designed according to the required support height h. Along the first direction, within the upward-sloping region 441, the spacing between adjacent joint lines 331 gradually decreases from front to back, meaning the diameter φ of the cylindrical joint chamber 321 gradually decreases; within the downward-sloping region 442, the spacing between adjacent joint lines 331 gradually increases; that is, along the first direction, the diameter φ of the plurality of cylindrical joint chambers 321 gradually increases from front to back. In other words, within the staggered region 440, along the first direction, the diameter φ of the plurality of cylindrical joint chambers 321 decreases sequentially from front to back and then increases sequentially. Optionally, the diameter φ of the cylindrical joint chamber 321 is between 2cm and 8cm, for example, it can be 2cm, 3cm, 4cm, 6cm, 8cm, etc. Preferably, the diameter φ of the cylindrical joint chamber 321 is between 2cm and 4cm. Further, the joint chamber 321 can be parallel to the first tensioning member within the main support 200, meaning the joint line 331 is parallel to the weld 211.

[0102] Reference Figure 4The seam line 331 is a complete solid line segment. Along the second direction, the size of the seam line 331 is smaller than the size of the upper piece 311 and the lower piece 312. That is, at least one end of the seam line 331 has a gap with the edge of the second outer wall 310. Thus, adjacent cylindrical seam chambers 321 can be connected through the gap between the seam line 331 and the edge of the second outer wall 310. (Refer to...) Figure 5 Optionally, the seam line 331 can be a dashed line segment, meaning there is at least one gap in the middle of the seam line 331, allowing adjacent cylindrical seam chambers 321 to communicate through this gap. In this case, along the second direction, the size of the seam line 331 can be equal to the size of the upper piece 311 and the lower piece 312, meaning the end of the seam line 331 can intersect with the edge of the upper piece 311 or the lower piece 312, and adjacent cylindrical seam chambers 321 remain fluidly connected. Because of this fluid communication between adjacent seam chambers 321, the auxiliary support 300 only needs one air inlet / outlet to inflate or deflate all seam chambers 321. (Refer to...) Figure 6 Optionally, the seam line 331 can be a complete solid line segment and its size along the second direction is equal to the size of the upper piece 311 or the lower piece 312. In this case, the seam line 331 isolates two adjacent seam chambers 321. In this optional embodiment, each isolated seam chamber 321 needs a separate air inlet / outlet for separate inflation or deflation. That is, the auxiliary support 300 needs to be provided with an equal number of air inlets / outlets as the isolated seam chambers 321.

[0103] Reference Figure 7In an optional embodiment, the height-limiting structure 330 includes a second tensioning member 332. The second tensioning member 332 has an upper side and a lower side. The upper side of the second tensioning member 332 is connected to the upper piece 311 of the second outer wall 310, and the lower side of the second tensioning member 332 is connected to the lower piece 312 of the second outer wall 310. Multiple second tensioning members 332 are provided. Along the first direction, the multiple second tensioning members 332 are distributed at a preset interval to divide the second chamber 320 of the auxiliary support 300 into multiple tension chambers 322. The second tensioning members 332 extend along the second direction, and the multiple second tensioning members 332 are arranged parallel to each other. Furthermore, the multiple tension chambers 322 are fluid-connected. Correspondingly, when the auxiliary support 300 is inflated, multiple sequentially arranged and parallel columnar tension chambers 322 are formed within the auxiliary support 300, and the multiple tension chambers 322 extend along the second direction respectively. The foremost and rearmost tension chambers 322 are defined by a second tensioning member 332 and an upper piece 311 and a lower piece 312 located between the second tensioning member 332 and the edge of the second outer wall 310. Each of the remaining tension chambers 322 is defined by two adjacent second tensioning members 332 and an upper piece 311 and a lower piece 312 located between the two adjacent second tensioning members 332. When the auxiliary support 300 is in an inflated state, the support height h of the columnar tension chamber 322 between two adjacent second tensioning members 332 is limited by the tension height h0 of the two second tensioning members 332. Therefore, the tension height h0 of the second tensioning member 332 can be designed according to the required support height h of the tension chamber 322. Along the first direction, within the upward tilting region 441, the tension height h0 of the second tensioning member 332 gradually decreases; within the downward tilting region 442, the tension height h0 of the second tensioning member 332 gradually increases. That is, along the first direction, within the staggered region 440, the tension height h0 of the second tensioning member 332 decreases sequentially and then increases sequentially. Furthermore, the tensioning chamber 322 can be parallel to the first tensioning member within the main support 200, i.e., the second tensioning member 332 is parallel to the weld 211.

[0104] Reference Figure 8 and Figure 9 In an optional embodiment, the height-limiting structure 330 of the auxiliary support 300 includes a seam line 331 and a second tensioning member 332, the distribution of which can be configured according to actual needs. For example, refer to... Figure 8The distribution of the second tensioning member 332 and the seam line 331 is divided according to different regions of the upper inclined region 441 and the lower inclined region 442. In the upper inclined region 441, the height limiting structure 330 consists entirely of the second tensioning member 332, and in the lower inclined region 442, the height limiting structure 330 consists entirely of the seam line 331. That is, along the first direction, in the staggered region 440, the support height of the multiple tensioning chambers 322 gradually decreases from front to back, and the support height of the multiple seam chambers 321 gradually increases from front to back. Alternatively, in an optional embodiment, in the upper inclined region 441, the height limiting structure 330 consists entirely of the seam line 331, and in the lower inclined region 442, the height limiting structure 330 consists entirely of the second tensioning member 332. That is, along the first direction, in the staggered region 440, the support height of the multiple seam chambers 321 gradually decreases from front to back, and the support height of the multiple tensioning chambers 322 gradually increases from front to back. For example, refer to Figure 9 The distribution of the second tensioning member 332 and the seam line 331 is divided according to the size of the height preset value H compared with the required support height h. When the required support height h is greater than or equal to the height preset value H, the height limiting structure 330 is the second tensioning member 332. When the required support height h is less than the height preset value H, the height limiting structure 330 is the seam line 331. That is to say, in this embodiment, the support height of the tensioning chamber 322 is greater than the support height of the seam chamber 321. In optional embodiments, the seam line 331 and the second tensioning member 332 can divide the second chamber 320 into one seam chamber 321 and one tensioning chamber 322; or, the seam line 331 and the second tensioning member 332 can divide the second chamber 320 into multiple seam chambers 321 and one tensioning chamber 322; or, the seam line 331 and the second tensioning member 332 can divide the second chamber 320 into one seam chamber 321 and multiple tensioning chambers 322; or, the seam line 331 and the second tensioning member 332 can divide the second chamber 320 into multiple seam chambers 321 and multiple tensioning chambers 322.

[0105] Reference Figure 1The main support body 200 may further include a first connecting piece 220, which has an upper side and a lower side. The upper side of the first connecting piece 220 is fixedly connected to the outer wall 110 of the main body of the mattress body 100 by welding or adhesive, and the lower side of the first connecting piece 220 is fixedly connected to the first outer wall 210 of the main support body 200 by welding or adhesive. Optionally, the first connecting piece 220 may be integrally formed on the first outer wall 210 of the main support body 200, that is, the first connecting piece 220 is a portion extending from the edge of the first outer wall 210 and fixedly connected to the outer wall 110 of the main body of the mattress body 100 by welding or adhesive. By connecting the main support body 200 and the mattress body 100 through the first connecting piece 220, the position of the main support body 200 relative to the mattress body 100 is fixed, and the vehicle mattress fits more stably with the vehicle's internal structure 400 during use. Furthermore, the main support body 200 also includes a first connecting valve (not shown), which comprises a first upper valve body and a first lower valve body. The first upper valve body and the first lower valve body are sealed together, and their internal fluids are in communication when connected. The first upper valve body is fixed to the outer wall 110 of the main body of the mattress body 100 and is in fluid communication with the main body chamber of the mattress body 100. The first lower valve body is fixed to the first outer wall 210 of the main support body 200 and is in fluid communication with the first chamber of the main support body 200. Thus, when the first upper valve body and the first lower valve body are connected, the main body chamber of the mattress body 100 is in fluid communication with the first chamber of the main support body 200. In this way, only one of the main support body 200 and the mattress body 100 needs to be provided with a valve port for connecting an air pump, and the main support body 200 and the mattress body 100 can be simultaneously inflated or deflated through this single valve port. In an optional embodiment, multiple first connecting valves can be provided. Multiple first connecting valves can fix the mattress body 100 and the main support body 200, so that the relative position of the mattress body 100 and the main support body 200 is stable. In this case, the first connecting piece 220 can be omitted, and the structure of the vehicle mattress can be made stable during use.

[0106] Reference Figure 1The auxiliary support 300 may further include a second connecting piece 340, which has an upper side and a lower side. The upper side of the second connecting piece 340 is fixedly connected to the outer wall 110 of the main body of the mattress body 100 by welding or adhesive, and the lower side of the second connecting piece 340 is fixedly connected to the second outer wall 310 of the auxiliary support 300 by welding or adhesive. Optionally, the second connecting piece 340 may be integrally formed on the second outer wall 310 of the auxiliary support 300, that is, the second connecting piece 340 is a portion extending from the edge of the second outer wall 310 and fixedly connected to the outer wall 110 of the main body of the mattress body 100 by welding or adhesive. By connecting the auxiliary support 300 to the mattress body 100 through the second connecting piece 340, the position of the auxiliary support 300 relative to the mattress body 100 is fixed, and the vehicle mattress fits more stably with the vehicle's internal structure 400 during use. Furthermore, the auxiliary support 300 also includes a second connecting valve (not shown), which comprises a second upper valve body and a second lower valve body. The second upper valve body and the second lower valve body are sealed together, and their internal fluids are in communication when connected. The second upper valve body is fixed to the outer wall 110 of the main body of the mattress body 100 and is in fluid communication with the main body chamber of the mattress body 100. The second lower valve body is fixed to the second outer wall 310 of the auxiliary support 300 and is in fluid communication with the second chamber 320 of the auxiliary support 300. Thus, when the second upper valve body and the second lower valve body are connected, the main chamber of the mattress body 100 is in fluid communication with the second chamber 320 of the auxiliary support 300. In this way, only one of the auxiliary support 300 and the mattress body 100 needs to be provided with a valve port for connecting an air pump, and both the auxiliary support 300 and the mattress body 100 can be simultaneously inflated or deflated through this single valve port. In an optional embodiment, multiple second connecting valves can be provided. Multiple second connecting valves can fix the mattress body 100 and the auxiliary support 300, so that the relative position of the mattress body 100 and the auxiliary support 300 is stable. In this case, the second connecting piece 340 can be omitted, and the structure of the vehicle mattress can be made stable during use.

[0107] Furthermore, in an optional embodiment, the main chamber of the mattress body 100 is fluidly connected to the first chamber of the main support body 200 via a first connecting valve, and simultaneously, the main chamber of the mattress body 100 is fluidly connected to the second chamber 320 of the auxiliary support body 300 via a second connecting valve. In this case, only one of the mattress body 100, the main support body 200, and the auxiliary support body 300 needs to be equipped with a valve port, allowing simultaneous inflation and deflation of all three components through that single valve port.

[0108] Reference Figure 10In an alternative embodiment, multiple auxiliary supports 300 are provided. The second outer wall 310 of each auxiliary support 300 can be formed by connecting one, two, or more sheets to form a closed structure. When the second chamber 320 of the auxiliary support 300 is filled with gas, the second chamber 320 of the auxiliary support 300 becomes cylindrical, that is, the auxiliary support 300 forms an independent cylindrical shape. The cylindrical second chamber 320 extends along a second direction, that is, the cylindrical auxiliary support 300 extends along the second direction. At this time, the auxiliary support 300 does not have a height limiting structure 330. Furthermore, the multiple auxiliary supports 300 are sequentially distributed along a first direction on the vehicle interior structure 400 within the staggered area 440. Specifically, within the upward-sloping region 441, along the first direction, the diameters of the cylindrical second chambers 320 of the plurality of auxiliary supports 300 gradually decrease from front to back; within the downward-sloping region 442, along the first direction, the diameters of the cylindrical second chambers 320 of the plurality of auxiliary supports 300 gradually increase from front to back. That is, along the first direction, within the staggered region 440, the diameters of the cylindrical second chambers 320 of the plurality of auxiliary supports 300 decrease sequentially and then increase sequentially. Optionally, the diameters of the cylindrical second chambers 320 of the plurality of auxiliary supports 300 are between 2cm and 8cm, for example, 2cm, 3cm, 4cm, 6cm, 8cm, etc. Preferably, the diameters of the cylindrical second chambers 320 of the plurality of auxiliary supports 300 are between 2cm and 4cm. Adjacent auxiliary supports 300 can contact each other. Optionally, two adjacent auxiliary support bodies 300 can be connected to each other. For example, the second outer wall 310 surfaces of two adjacent auxiliary support bodies 300 are provided with bristles and connected to each other through the bristles; or, the ends of two adjacent auxiliary support bodies 300 are provided with snap fasteners and connected to each other through the snap fasteners, etc. Optionally, the second chambers 320 of two adjacent auxiliary support bodies 300 can be fluidly connected to each other through a connecting valve; or, the second chamber 320 of each auxiliary support body 300 is fluidly connected to the main chamber of the mattress body 100, so that the second chambers 320 of multiple auxiliary support bodies 300 can achieve common fluid communication through the main chamber of the mattress body 100. Further, the second chamber 320 of each auxiliary support body 300 can be parallel to the first tensioning member in the main support body 200, that is, each cylindrical auxiliary support body 300 is parallel to the weld 211.

[0109] It should be noted that the above embodiments use the example of a staggered area 440 containing one upward-sloping area 441 and one downward-sloping area 442, and are not restrictive. In practice, the staggered area 440 may contain only one downward-sloping area 442 and not the upward-sloping area 441; or, the staggered area 440 may contain only one upward-sloping area 441 and not the downward-sloping area 442; or, the staggered area 440 may contain one upward-sloping area 441 and multiple downward-sloping areas 442; or, the staggered area 440 may contain multiple upward-sloping areas 441 and one downward-sloping area 442; or, the staggered area 440 may contain multiple upward-sloping areas 441 and multiple downward-sloping areas 442, and so on. The auxiliary support 300 can be modified accordingly based on the actual staggered area 440.

[0110] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
