[0027] The following is for reference. Figures 1-5 A seat assembly 100 for a vehicle according to an embodiment of a first aspect of the present invention is described.

[0028] like Figures 1-5 As shown, a seat assembly 100 for a vehicle according to a first aspect embodiment of the present invention includes a first support frame 1, a second support frame 2 and a third support frame 3.

[0029] Specifically, the first support frame 1 is adapted to be rotatably connected to the floor 400, meaning the first support frame 1 can be located on one side of the floor 400 adjacent to the vehicle interior. The second support frame 2 is located in the first direction (e.g., Figure 1 One end of the third support frame 3 (in the front-back direction) is rotatably connected to the first support frame 1. The third support frame 3 is rotatably connected to the other end of the second support frame 2 in the first direction. The third support frame 3 is located at the second support frame 2 in the second direction (e.g., in the front-back direction). Figure 1 (The vertical direction) on one side and the second direction extends.

[0030] For example, in Figures 1-5In the example, the first support frame 1 can rotate relative to the base plate 400. The first support frame 1, the second support frame 2, and the third support frame 3 constitute the seat assembly 100. The first support frame 1 and the third support frame 3 are respectively located on both sides of the second support frame 2 in a first direction. When the seat assembly 100 is in the first state, both the first support frame 1 and the second support frame 2 abut against the base plate 400, that is, the first support frame 1 and the second support frame 2 can support the seat cushion, making it convenient for the user to sit. At this time, the third support frame 3 is located on the side of the second support frame 2 away from the base plate 400, and the third support frame 3 can form the seat back.

[0031] In this configuration, the third support frame 3 is rotatably connected to the second support frame 2 at the other end in the first direction, allowing the angle between the third support frame 3 and the second support frame 2 to be adjusted. With this configuration, when the seat assembly 100 is in the first state, the tilt angle of the third support frame 3 can be adjusted, increasing user comfort. The first support frame 1 and the second support frame 2 are rotatably connected at one end in the first direction, allowing the second support frame 2 to rotate around the connection point between the first and second support frames 1 and 2. When the second support frame 2 rotates 180°, it rotates above the first support frame 1, with the first support frame 1 and the third support frame 3 located on the side of the second support frame 2 adjacent to the base plate 400. The end of the third support frame 3 furthest from the second support frame 2 abuts against the base plate 400, and the seat assembly 100 switches to the second state, where it forms a ladder shape.

[0032] In the vehicle, the seat assembly 100 has an upper berth 200 and a lower berth 300 on the side away from the windshield, and the upper berth 200 and lower berth 300 are spaced apart along a second direction. Figure 1 As shown, when the user is driving the vehicle, the seat assembly 100 can be switched to the first state, that is, the second support frame 2 is positioned adjacent to the lower berth 300, and the first support frame 1 is located on the side of the second support frame 2 away from the lower berth 300. In this state, the seat assembly 100 is used for charging. Figure 3 As shown, when a user needs to rest in the upper berth 200, by rotating the second support frame 2 180° around the connection between the first support frame 1 and the second support frame 2, the third support frame 3 abuts against the base plate 400, making the seat assembly into a ladder shape. The user can climb to the upper berth 7 by stepping on the first support frame 1 and the second support frame 2.

[0033] In the existing technology, the cab of medium and large heavy trucks is equipped with an upper berth and a lower berth, but there is no effective stepping structure in the cab. Most users use the armrests of the driver's seat or the passenger seat to step on and assist in climbing. The contact area of ​​the armrests is small, and the angle of the armrests changes with the angle of the backrest. There is no fixed position, which makes it inconvenient to step on when climbing.

[0034] In this application, by rotatably connecting the second support frame 2 to the first support frame 1, when a user needs to rest on the upper berth 7, the second support frame 2 is rotated 180° around the connection point of the first support frame 1 and the second support frame 2, transforming the seat assembly 100 into a ladder shape. The user can then climb to the upper berth 7 by stepping on the first support frame 1 and the second support frame 2, which facilitates the user's climb to the upper berth 7. During the climb, both the first support frame 1 and the third support frame 3 are stably anchored to the base plate 400, ensuring the stability of the user's climb and thus guaranteeing the user's safety.

[0035] According to an embodiment of the present invention, the seat assembly 100 for a vehicle allows the second support frame 2 to be rotatably connected to the first support frame 1, enabling the seat assembly 100 to switch between a first state and a second state. Therefore, compared to conventional vehicle seat assemblies, this facilitates the user's climb to the upper berth 7, ensures stability during the climb, and thus guarantees the user's safety.

[0036] According to some embodiments of the present invention, the second support frame 2 includes a first support plate 21, a plurality of first supports 22, and at least one second support 23. In the description of the present invention, "a plurality of" means two or more. The first support plate 21 is rotatably connected to the first support frame 1 and the third support frame 3 at its two ends in a first direction, respectively. The plurality of first supports 22 are all disposed on the side of the first support plate 21 away from the second support frame, and the plurality of first supports 22 are arranged along a third direction (e.g., ...). Figure 1 The first, second, and third directions are spaced apart (left and right), and intersect each other. The second support 23 is connected between the multiple first supports 22.

[0037] Reference Figures 1-5 The plane of the first support plate 21 is parallel to the plane of the base plate 400. The first support plate 21 is connected to a first support frame 1 and a third support frame 3 on both sides in the first direction. When the seat assembly 100 is in the first state, the first support frame 1 and the third support frame 3 are located on both sides of the first support plate 21 in the second direction. There can be two first brackets 22, located on both sides of the first support plate 21 in the third direction. There can be four second brackets 23, divided into two groups. The two groups of second brackets 23 are spaced apart along the second direction, and the two second brackets 23 in the same group are spaced apart along the first direction. Each second bracket 23 extends along the third direction. The four second brackets 23 fix two first brackets 22 together, enhancing the structural strength of the first brackets 22, strengthening the supporting role of the second support frame 2, and improving the stability of the seat assembly 100.

[0038] When the seat assembly 100 switches to the second state, the first bracket 22 and the second bracket 23 rotate above the first support frame 1. At this time, the first support frame 1, the first support plate 21 and the second bracket 23 can form three steps, and the two second brackets 23 in the same group can form a stepping surface. When climbing, the user can climb to the upper berth 200 by stepping on the first support frame 1, the first support plate 21 and the second bracket 23. In this way, the contact area between the user and the seat assembly 100 during the climbing process is increased, which can further ensure the stability and safety during the climbing process.

[0039] Furthermore, each first support 22 includes a first sub-support segment 221, a second sub-support segment 222, and a third sub-support segment 223 connected to each other. The second sub-support segment 222 is connected between the first sub-support segment 221 and the third sub-support segment 223. Both the first sub-support segment 221 and the third sub-support segment 223 are along a second direction (e.g., Figure 1 The second sub-support segment 222 extends along the first direction (e.g., in the vertical direction), and extends along the first direction (e.g., in the vertical direction). Figure 1 It extends in the front-to-back direction. Among them, along the direction toward the first support plate 21, the distance between the first sub-support segment 221 and the third sub-support segment 223 gradually increases in the third direction.

[0040] like Figures 1-5 As shown, the first sub-support segment 221 is perpendicular to the first support plate 21. A portion of the third sub-support segment 223 extends obliquely towards the first support plate 21 in the second direction, while the remaining portion of the third sub-support segment 233 is flush with the first sub-support segment 221 in the second direction, so that the distance between the first sub-support segment 221 and the third sub-support segment 223 gradually increases in the first direction towards the first support plate 21. The second sub-support segment 222 connects the first sub-support segment 221 and the third sub-support segment 223, so that the first support 22 formed by the first sub-support segment 221, the second sub-support segment 222, and the third sub-support segment 223 is approximately a right-angled trapezoid. This strengthens the structural strength of the first support 22, thereby improving its stability and, consequently, the stability and safety of the seat assembly 100, ensuring the safety of the user.

[0041] Furthermore, a locking frame 24 is provided on the side of the second sub-support segment 222 away from the first support plate 21. The seat assembly 100 also includes a plurality of locking mechanisms 5, all of which are provided on the base plate 400. Each locking mechanism 5 switches between a locked state and an unlocked state. When each locking mechanism 5 is in the locked state, the locking frame 24 is connected to the locking mechanism 5. When each locking mechanism 5 is in the unlocked state, the locking frame 24 is separated from the locking mechanism 5.

[0042] For example, in Figures 1-5In the example, the locking frame 24 can be connected to the locking mechanism 5. The locking mechanism 5 is opposite to the second support frame 2 in the second direction. There can be two locking mechanisms 5, and the two locking mechanisms 5 can be connected to the same locking bracket 24. Specifically, the locking mechanism 5 includes a body 51 and a locking part 52. The body 51 has a receiving cavity 511, the locking part 52 is disposed in the receiving cavity 511, and the locking part 52 is rotatably connected to the body 51. The cross-sectional shape of the locking part 52 is hook-shaped, and the body 51 is provided with a limiting groove 512. When the locking frame 24 is engaged with the limiting groove 512, the locking part 52 engages with the locking frame 24, and the locking part 52 fixes the locking frame 24 in the limiting groove 512, restricting the displacement of the locking frame 24 in a direction away from the locking mechanism 5, thereby achieving locking. When the locking part 52 rotates away from the locking frame 24, the locking part 52 separates from the locking frame 24, and the locking mechanism 5 switches to the unlocked state.

[0043] When the locking mechanism 5 is connected to the locking frame 24, the second support frame 2 and the first support frame 1 are side by side in the first direction, and the position of the second support frame 2 is fixed and cannot be rotated. At this time, the seat assembly 100 is used for user seating. When the locking mechanism 5 is switched to the unlocked state, the connection between the locking frame 24 and the locking mechanism 5 is disconnected, and the second support frame 2 can rotate. At this time, by rotating the second support frame 2 180° around the connection point of the first support frame 1 and the second support frame 2, the seat assembly 100 can act as a ladder. The user can climb to the upper berth 200 by stepping on the first support frame 1 and the second support frame 2. At this time, the locking frame 24 can act as a handrail. Thus, the seat assembly 100 can meet the needs of user seating and user climbing to the upper berth 7, improving the user's travel experience and safety.

[0044] According to some embodiments of the present invention, the seat assembly 100 for a vehicle further includes an auxiliary handle 6. The auxiliary handle 6 is disposed on one side of the first support frame 1 adjacent to the rotating plate 4, and one end of the auxiliary handle 6 is connected to a plurality of locking mechanisms 5. The auxiliary handle 6 switches between an open position and a closed position.

[0045] When the auxiliary handle 6 is in the open position, the locking mechanism 5 is in the unlocked state; when the auxiliary handle 6 is in the closed position, the locking mechanism 5 is in the locked state.

[0046] Reference Figures 1-5The auxiliary handle 6, connected to the locking mechanism 5, can control the locking mechanism 5 to switch between locked and unlocked states. Specifically, the auxiliary handle 6 includes a handle 61, a first pull cable 62, a first transmission rod 63, and a second transmission rod 64. One end of the first pull cable 62 is connected to the first transmission rod 63 and the handle 61. The first pull cable 62 passes through the second transmission rod 64 and splits into a first sub-pull cable 621 and a second sub-pull cable 622. The first sub-pull cable 621 and the second sub-pull cable 622 are respectively connected to the locking part 52 of the corresponding locking mechanism 5. Both the first sub-pull cable 621 and the second sub-pull cable 622 are connected to the pivot of the locking part 52. Thus, when the user pulls the handle 61, causing it to rotate away from the first support frame 1, the first pull cable 62 is also pulled, causing the first sub-pull cable 621 and the second sub-pull cable 622 to respectively pull the corresponding locking part 52 to rotate, causing the locking part 52 to rotate away from the locking frame 24, and the locking mechanism 5 switches to the unlocked state. When the user releases the handle 61, the first pull cable 62 moves with the handle 61, and the first sub-pull cable 621 and the second sub-pull cable 622 no longer exert tension on the locking part 52, causing the locking part 52 to rotate to the locked state. This design facilitates the user in switching the state of the seat assembly 100, thereby improving the user experience.

[0047] According to some embodiments of the present invention, each first support 22 further includes a fourth sub-support segment 224, the two ends of which are connected to the first sub-support segment 221 and the third sub-support segment 223, respectively, and the fourth sub-support segment 224 is located on the side of the second sub-support segment 222 adjacent to the first support plate 21. Figures 1-5 As shown, the fourth sub-support segment 224 extends along the first direction and is parallel to the second sub-support segment 222. The fourth sub-support segment 224 strengthens the support of the first sub-support segment 221 and the third sub-support segment 223, thereby improving the support function of the first support 22, making the structure of the seat assembly 100 more stable, and further improving safety.

[0048] According to some embodiments of the present invention, the first support frame 1 includes a rotating plate 4, a second support plate 11, a plurality of third brackets 12, and at least one fourth bracket 13. The rotating plate 4 is rotatably connected to the vehicle floor 400. The second support plate 11 is rotatably connected to the second support frame 2. The plurality of third brackets 12 are spaced apart along a third direction, and one end of each third bracket 12 is connected to one side of the second support plate 11 adjacent to the floor 400 in a second direction, and the other end of each third bracket 12 is fixedly connected to the floor 400 in the second direction. The fourth bracket 13 is connected between two adjacent third brackets 12.

[0049] For example, in Figures 1-5In the example, the first support frame 1 is connected to the rotating plate 4 by bolts or welding. The rotating plate 4 has a circular cross-section and can rotate around its central axis. The second support plate 11 is located on one side of the first support plate 21 in a first direction and extends along a second direction. The width of the second support plate 11 in the first direction is smaller than the width of the first support plate 21. There can be two third supports 12, located at opposite ends of the second support plate 11 in a third direction. A fourth support 13 extends along a third direction and is positioned between the two third supports 12. There can be three fourth supports 13, spaced apart along the first direction. The second support plate 11 is rotatably connected to the first support plate 21 of the second support frame 2 in the first direction, allowing the second support frame 2 to rotate around this side. The first support frame 1 is fixed on the rotating plate 4. When the rotating plate 4 rotates 180°, the second support frame 2 rotates 180° around the aforementioned side of the second support plate 11. Thus, the seat assembly 100 can be switched from the first state to the second state. When the user climbs onto the upper berth 7, the structure of the first support frame 1 is stable, which enhances the structural stability of the seat assembly 100 and ensures safe use.

[0050] In addition, such as Figure 2 As shown, by fixing the first support frame 1 to the rotating plate 4, and rotating the plate 4 to the base plate 400, when the seat assembly 100 is switched to the second state, rotating the plate 4 by 180° can increase the space between the lower berth 300 and the first support frame 1, which is conducive to placing the rotated third support frame 3 and giving the third support frame 3 sufficient space to move.

[0051] Optionally, the auxiliary handle 6 also includes a second cable 65, which is connected to the base plate 400 and can control the rotation of the rotating plate 4. This facilitates the user's use of the seat to climb to the upper berth 7 and also improves the stability and safety of the seat assembly 100.

[0052] Furthermore, each third support 12 includes a fifth sub-support segment 121 and a sixth sub-support segment 122, both of which extend along a second direction. The distance between the fifth sub-support segment 121 and the sixth sub-support segment 122 gradually decreases along the direction toward the second support plate 11 in the first direction.

[0053] Reference Figures 1-5A portion of the fifth sub-support segment 121 extends obliquely from the side adjacent to the second support plate 11 in a direction away from the sixth sub-support segment 122. The fifth sub-support segment 121 and the sixth sub-support segment 122 form a triangle, which enhances the structural stability of the third support 12, thereby enhancing the supporting effect of the third support 12, making the structure of the first support frame 1 stable, and improving the stability of the seat assembly 100.

[0054] According to some embodiments of the present invention, the third support frame 3 includes a support frame 31 and at least one reinforcing rib 32. One end of the support frame 31 is rotatably connected to the second support frame 2. The reinforcing rib 32 is disposed within the support frame 31 and has a wavy shape.

[0055] like Figures 1-5 As shown, the cross-sectional shape of the support frame 31 is approximately rectangular. The length direction of the support frame 31 (e.g., Figure 1 One side of the seat assembly 100 (in the vertical direction) is rotatably connected to the second support frame 31. The support frame 31 can rotate to adjust its angle, improving user comfort. There can be three reinforcing ribs 32, spaced apart along the length of the support frame 31. These ribs enhance the structural strength of the support frame 31, ensuring higher structural strength of the seat assembly 100 when the user sits or climbs, preventing breakage of the support frame 31, extending its service life, and improving the safety and stability of the seat assembly 100.

[0056] A vehicle (not shown) according to a second aspect embodiment of the present invention includes a seat assembly 100 for a vehicle according to the first aspect embodiment described above.

[0057] According to the vehicle of the present invention, by adopting the above-described seat assembly 100, the seat assembly 100 can be used for user seating and can also be switched to a ladder structure, which facilitates the user to climb to the upper berth 300 via the seat assembly 100, thereby improving the user's riding experience and safety.
