Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0043] Please refer to Figures 1 to 3 This application provides a toilet structure, a driver's cab, and a vehicle. The toilet structure, driver's cab, and vehicle are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.
[0044] This application provides a bathroom structure, which includes a bathroom body 10 and a bathroom door 20.
[0045] The main body of the toilet 10 has a doorway 11. Sanitary facilities and shower facilities can be installed inside the main body of the toilet 10. Users can enter the main body of the toilet 10 through the doorway 11 to use the sanitary facilities and shower facilities. The sanitary facilities include, but are not limited to, a toilet, and the shower facilities include, but are not limited to, a shower structure and a sink structure.
[0046] The bathroom door 20 includes a first main door 21, a second main door 22, and a first auxiliary door 23. The first main door 21 and the second main door 22 are rotatably connected to opposite sides of the bathroom body 10, that is, the first main door 21 is rotatably connected to one side of the bathroom body 10, and the second main door 22 is rotatably connected to the other side of the bathroom body 10. The first auxiliary door 23 is movably connected to the first main door 21, and the movable connection method includes, but is not limited to, rotation.
[0047] The bathroom door 20 has a storage position and an extended position. In the storage position, the first main door 21 and the second main door 22 rotate to the doorway 11, closing the doorway 11. The first secondary door 23 overlaps with the first main door 21. Here, "overlapping" means that the first secondary door 23 and the first main door 21 are stacked on top of each other, and at least part of the structure of the first secondary door 23 is attached to the first main door 21. In the extended position, the first main door 21 and the second main door 22 rotate to the outside of the doorway 11. Here, "outside" means the side of the doorway 11 away from the bathroom body 10. The first secondary door 23 is located between the first main door 21 and the second main door 22, and together with the first main door 21 and the second main door 22, it closes the doorway 11.
[0048] By adopting the above solution, when the bathroom is not frequently used, the door can be stored away. The first main door 21 and the second main door 22 rotate to close the doorway 11, and the first secondary door 23 overlaps with the first main door 21. At this time, the bathroom door 20 is basically flush with the main bathroom 10, reducing the overall area occupied by the bathroom in the vehicle and effectively improving the usability of the vehicle's interior space when the bathroom is not in use. When there is a need to use the bathroom, especially for showering or washing up, the user can adjust the bathroom door 20 to the extended position. The first main door 21 and the second main door 22 rotate to the outside of the doorway 11, and the first secondary door 23 is located between them, together closing the doorway 11. At this time, the first main door 21 and the second main door 22 are located outside the doorway 11, expanding the bathroom area and providing the user with a relatively spacious living space.
[0049] In summary, this solution allows for flexible adjustment of the actual usable area of the bathroom. When the bathroom is not needed, the bathroom door 20 can be adjusted to a storage position, reducing the space occupied by the bathroom and freeing up more space for other functions of the vehicle. When the bathroom is needed, the bathroom door 20 can be extended to provide users with a relatively spacious living area, better meeting their basic living needs.
[0050] Please refer to Figures 4 to 7 and combined Figure 1In one embodiment, the bathroom door 20 further includes a second auxiliary door 24, which is movably connected to the second main door 22, and the connection method includes, but is not limited to, rotation. In the retracted position, the second auxiliary door 24 is stacked on top of the second main door 22; in the extended position, both the first auxiliary door 23 and the second auxiliary door 24 are located between the first main door 21 and the second main door 22, and together with the first main door 21 and the second main door 22, they close the doorway 11.
[0051] Thus, on the one hand, from the perspective of spatial enclosure, the space enclosed by the first auxiliary door 23, the second auxiliary door 24, the first main door 21, and the second main door 22 is larger than the space enclosed by only the first auxiliary door 23, the first main door 21, and the second main door 22. This allows the overall space of the bathroom to be larger in the aforementioned extended position, thereby improving the user experience. On the other hand, with the bathroom space remaining unchanged, when only the first auxiliary door 23, the first main door 21, and the second main door 22 were used to enclose the entrance 11 and form an enclosed space, the first auxiliary door 23 needed to cover a large spatial span to ensure effective enclosure and expansion of sufficient bathroom usable area. However, with the addition of the second auxiliary door 24, the second auxiliary door 24 shares part of the spatial span that the first auxiliary door 23 originally needed to cover. The two auxiliary doors extend from both sides towards the middle simultaneously to complete the enclosure of the space at the entrance 11, so that the first auxiliary door 23 does not need to be as long as before to meet the needs of enclosure and expansion of space. Therefore, adding a second auxiliary door 24 in this solution can reduce the length of the first auxiliary door 23, which can make the entire bathroom door structure 20 more stable and reduce the structural risks caused by the excessive length of the first auxiliary door 23.
[0052] Furthermore, in the retracted position, the first auxiliary door 23 is located inside the doorway 11, and the second auxiliary door 24 is located inside the doorway 11. Retracting the first auxiliary door 23 and the second auxiliary door 24 inside the doorway 11 allows the toilet door 20 to fit more tightly against the toilet body 10 when not in use. This layout effectively avoids the door extending abruptly into other spaces within the vehicle, reduces the occupation of external space, and makes the overall interior space layout more regular, creating a more spacious and fluid movement space for passengers.
[0053] In one embodiment, the rotation angle of the first main door 21 from the storage position to the extended position is an acute angle.
[0054] Of course, the rotation angle of the second main door 22 from the storage position to the expansion position is an acute angle.
[0055] When the first main door 21 or the second main door 22 rotates from its retracted position to its extended position at an acute angle, it means that during the unfolding process, the first main door 21 or the second main door 22 does not need to rotate significantly to achieve the transformation from a closed doorway 11 to an extended bathroom space. This greatly improves space utilization efficiency for vehicles with extremely limited interior space, such as RVs and campervans. For example, if a bathroom is placed next to a narrow aisle in a vehicle, a large rotation angle of the main door would severely obstruct passage. The acute-angle rotation design, however, can meet the need for bathroom space expansion while minimizing the occupation of aisle and other public spaces.
[0056] Furthermore, the rotation angle of the first main door 21 from the storage position to the extended position is between 20° and 70°. Within this range, the rotation angle of the first main door 21 allows for a suitable expansion of the bathroom's usable area while minimizing impact on the surrounding structure.
[0057] For example, the rotation angle of the first main door 21 from the storage position to the extended position can be 20°, 30°, 40°, 50°, 60°, or 70°, but is not limited to these.
[0058] The second main door 22 rotates from the storage position to the extended position by an angle of 20° to 70°. Similarly, within this range, the rotation angle of the second main door 22 can appropriately expand the usable area of the bathroom while minimizing the impact on the surrounding structure.
[0059] For example, the rotation angle of the second main door 22 from the storage position to the extended position can be 20°, 30°, 40°, 50°, 60°, or 70°, but is not limited to these.
[0060] Please continue to refer to this. Figure 7 In one embodiment, the bathroom structure further includes a first seal 25 and a second seal 26; in the extended position, the first seal 25 is fixed to the side end of the first secondary door 23 away from the first main door 21 and extends along the height direction of the first secondary door 23, and the second seal 26 is fixed to the side end of the second secondary door 24 away from the second main door 22, extends along the height direction of the second secondary door 24, and abuts against the first seal 25.
[0061] When the first seal 25 and the second seal 26 are in the extended position, they abut against each other and extend along the height direction to form a continuous sealing barrier that can prevent water vapor from escaping.
[0062] Furthermore, the bathroom structure also includes locks installed on the first auxiliary door 23 and / or the second auxiliary door 24 to lock the first auxiliary door 23 and the second auxiliary door 24 in the extended position. The locks may be, but are not limited to, steel switch bolt locks, pin tumbler locks, and padlocks.
[0063] Please refer to Figure 8 and combined Figure 1 This application also provides a driver's cab, including the toilet structure, driver's cab enclosure 30, and first bed board 40 described in any of the above embodiments or implementations.
[0064] The cab enclosure 30 may include a roof, a floor, and side panels, with the side panels connecting the roof and the floor to form a closed receiving space 31. The toilet structure and the first bed board 40 are both installed within the receiving space 31. Specifically, the toilet structure may be fixed between the roof and the floor, and the first bed board 40 may be connected to any position within the cab enclosure 30 or adjacent to the toilet structure.
[0065] In one embodiment, the first bed board 40 is adjacent to the first main door 21 and located outside the rotation space of the first main door 21. This ensures that the first main door 21 will not interfere with the first bed board 40 when rotating to expand the bathroom space, thus ensuring the normal use of the bathroom door and improving the structural compactness.
[0066] Specifically, the first bed board 40 has a first clearance notch 41, and in the extended position, the outer wall of the first main door 21 is located within the first clearance notch 41. The design of the first clearance notch 41 allows the first bed board 40 to be positioned more closely to the first main door 21. Given the limited space in the cab, this layout avoids leaving a large amount of unused space between the bed board and the door due to the rotation space requirements of the first main door 21, effectively improving space utilization.
[0067] Furthermore, the cab also includes a second bed board 50 disposed in the accommodating space 31. The second bed board 50 is adjacent to the second main door 22 and located outside the rotation space of the second main door 22. Specifically, the second bed board 50 has a second clearance notch 51, and in the extended position, the outer wall of the second main door 22 is located below the second clearance notch 51. Similarly, this can improve space utilization.
[0068] In one embodiment, the length directions of both the first bed board 40 and the second bed board 50 are parallel to the length direction of the cab. The toilet structure is located between the first bed board 40 and the second bed board 50. Placing the toilet between two parallel bed boards fully utilizes the space that might otherwise be wasted, making more efficient use of the interior space of the cab. Furthermore, for the user, the toilet's location between the two bed boards means that regardless of which bed they get from, the distance to use the toilet is relatively short and the path is direct, improving convenience.
[0069] Furthermore, storage cabinets 70 can be installed under both the first bed board 40 and the second bed board 50 for users to store their belongings. The storage cabinets 70 can be integrated with the bathroom structure to improve compactness and save space.
[0070] In one embodiment, the cab also includes a driver's seat 60, with the first bed board 40 located above the driver's seat 60; within the limited accommodation space 31 of the cab, placing the first bed board 40 above the driver's seat 60 fully utilizes the vertical space and effectively improves space utilization.
[0071] In one embodiment, the cab further includes a passenger seat below the second bed board 50; wherein the second bed board 50 is movablely engaged with the cab surround 30 in the height direction, and the movable engagement includes, but is not limited to, sliding, moving, and rotating, so that the user can adjust the height of the second bed board as needed.
[0072] Furthermore, the passenger seat includes a passenger seat back and a passenger seat cushion, the passenger seat back being rotatably connected to the passenger seat cushion; the maximum angle between the passenger seat back and the passenger seat cushion is not less than 135°.
[0073] With this configuration, on the one hand, the backrest of the front passenger seat can rotate, and the maximum angle between it and the front passenger seat cushion is no less than 135°, providing passengers with a more comfortable resting posture. On the other hand, the front passenger seat backrest has a large rotation angle, and when the front passenger seat is reclined to its largest angle, the height of the second bed board 50 can be adjusted to a lower position, making it easier for users to get in and out.
[0074] This application also provides a vehicle including a toilet structure as described in any of the above embodiments; or a driver's cab as described in any of the above embodiments.
[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
