Description

Technical Field

[0001] This application relates to the field of transportation vehicles, and more particularly to a sleeper assembly, a driver's cab, and a vehicle. Background Technology

[0002] With the rapid development of the road transport industry, the occupational health of long-haul truck drivers has received increasing attention. Due to the time-sensitive nature of transport missions, drivers often need to take temporary breaks in the cab to alleviate fatigue; therefore, sleeper berths have become a core feature of modern vehicle cabs.

[0003] In related technologies, due to space limitations within the vehicle's cab, the sleeper berths in existing vehicles are typically designed to be small, failing to adequately support the driver and provide a comfortable rest. Furthermore, the seats and sleeper berths are often independent structures, unable to effectively integrate the cab space and thus fail to provide the driver with a more spacious and comfortable resting environment.

[0004] Therefore, it is necessary to provide an improved sleeper assembly to solve some or all of the above problems. Utility Model Content

Detailed Implementation

[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. 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.

[0034] like Figure 1 As shown, the sleeper assembly of this application includes a sleeper body 1 and a seat 2. The seat 2 is disposed adjacent to the sleeper body 1, and the seat 2 is foldable and can be combined with the sleeper body 1 to form a complete bed, thereby fully supporting people for rest. Specifically, the seat 2 includes a seat cushion 21 and a backrest 22, and the backrest 22 includes a lower seat portion 221 and an upper seat portion 222. The lower seat portion 221 is hinged between the seat cushion 21 and the upper seat portion 222. That is, one end of the lower seat portion 221 is hinged to the seat cushion 21, and the end opposite to the seat cushion 21 is hinged to the upper seat portion 222, so that the lower seat portion 221 can rotate relative to the seat cushion 21, and the upper seat portion 222 can rotate relative to the lower seat portion 221.

[0035] Further integration such as Figure 2 and Figure 3 As shown, in some embodiments, the sleeper assembly includes a reclining state and a backrest state for placing items. When the sleeper assembly is in the reclining state, the backs of the lower seat portion 221 and the upper seat portion 222 are used to support the human body. When the sleeper assembly is in the backrest state for placing items, the upper seat portion 222 is folded relative to the lower seat portion 221, and the back of the upper seat portion 222 is parallel to the upper side surface 11 of the sleeper body 1, and the back of the upper seat portion 222 can be used for placing items.

[0036] This design allows the sleeper berth assembly to offer both a reclining and a backrest position, satisfying both the need for lying flat and the need for leaning back, thus increasing the versatility of the sleeper berth assembly in terms of resting posture. Furthermore, when the sleeper berth assembly is in the backrest position, the back of the upper seat 222 can also support items such as mobile phones, water cups, and plates, improving the utilization efficiency and functionality of the sleeper berth assembly and ultimately enhancing the user experience.

[0037] The following provides a detailed description of the reclining and support / backrest states of the sleeper assembly. In some embodiments, the reclining states of the sleeper assembly include a flat reclining state and a leaning reclining state. When the sleeper assembly is in the flat reclining state, the backrest 22 is folded down to the seat cushion 21, meaning the lower seat portion 221 and the upper seat portion 222 rotate relative to the seat cushion 21, causing the back side of the backrest 22 to be flush with the upper side 11 of the sleeper body 1. This satisfies the need for people to lie flat and rest, providing a comfortable resting experience. It is worth noting that due to assembly tolerances and the influence of the surface materials of the backrest 22 and the sleeper body 1, the back side of the backrest 22 is approximately flush with the upper side 11 of the sleeper body 1.

[0038] To achieve a near-flush alignment between the backrest 22 and the upper side 11 of the berth body 1, making the berth assembly more comfortable to use, the seat includes a support frame (not shown). Specifically, the support frame is adjustable; when the backrest 22 is folded down to the seat cushion 21, the support frame automatically adjusts its shape and tension to ensure a smooth transition between the backrest 22 and the upper side 11 of the berth body 1, without any noticeable bumps or gaps, thereby improving the user experience.

[0039] When the sleeper assembly is in the reclining position, the backrest 22 folds towards the seat cushion 21, with the angle between the backrest 22 and the seat cushion 21 forming an acute angle, and the angle between the backrest 22 and the seat cushion 21 not exceeding 90 degrees. During this process, the upper seat section 222 locks into the lower seat section 221, and the back side of the upper seat section 222 is nearly flush with the back side of the lower seat section 221, with the upper seat section 222 and the lower seat section 221 folding together towards the seat cushion 21. This configuration meets the needs of people to lean back and rest.

[0040] like Figure 4 As shown, in some other embodiments, when the berth assembly is in a reclining state, the lower seat portion 221 rotates toward the seat cushion 21, such that the angle between the lower seat portion 221 and the seat cushion 21 is an acute angle, and the angle between the lower seat portion 221 and the seat cushion 21 does not exceed 90 degrees. Simultaneously, the upper seat portion 222 rotates relative to the lower seat portion 221 in a direction away from the seat cushion 21, so that the upper seat portion 222 is perpendicular to the upper side surface 11 of the berth body 1. It is worth noting that due to assembly and manufacturing tolerances, the upper seat portion 222 is approximately perpendicular to the upper side surface 11 of the berth body 1.

[0041] This design allows people to recline on the lower chair section 221 with their upper body tilted, while the upper chair section 222 can serve as a headboard for protection.

[0042] In this embodiment, the upper body can lie on the berth body 1, the legs can be placed on the lower seat 221, and the feet can touch the vertically arranged upper seat 222. This arrangement increases the variety of resting postures in the berth assembly and enhances the level of relaxation.

[0043] like Figure 5 and Figure 6 As shown, in some embodiments, when the berth assembly is in the backrest position, the upper chair portion 222 is folded relative to the lower chair portion 221, and the back side of the upper chair portion 222 is approximately parallel to the upper side surface 11 of the berth body 1, while the lower chair portion 221 can either rotate relative to the seat cushion 21 or remain stationary relative to the seat cushion 21, with only the upper chair portion 222 rotating.

[0044] Specifically, when the sleeper assembly is in the backrest position, on the one hand, the lower seat section 221 can rotate and the angle between it and the seat cushion 21 does not exceed 90 degrees, so that people can comfortably recline on the back of the lower seat section 221, while the back of the upper seat section 222 can be used to place items such as mobile phones and teacups, thereby improving the user experience. On the other hand, the lower seat section 221 can rotate or remain stationary so that the angle between it and the seat cushion 21 is obtuse. In this way, the back of the upper seat section 222 can be used to place dishes, etc., so that people can eat while sitting on the sleeper body 1, and at the same time, mobile phones can be placed for entertainment while sitting on the sleeper body 1.

[0045] When the sleeper assembly is in the storage backrest position, the upper chair part 222 and the lower chair part 221 cooperate to make the chair back 22 serve as both a headboard and a bedside table for storing items.

[0046] like Figures 7 to 9 As shown, in some embodiments, the chair back 22 may further include a shelf 223, which is hinged to the back of the lower seat portion 221 and can be retracted into and extended out of the lower seat portion 221. Since the shelf 223 is located on the back of the lower seat portion 221 and extends out of the lower seat portion 221, it is more convenient for users. To ensure that the back of the lower seat portion 221 remains flat when the shelf 223 is retracted into it, the lower seat portion 221 is provided with a recessed storage cavity 224, in which the shelf 223 can be stored.

[0047] In addition, when the sleeper assembly is in a flat position, the storage panel 223 can extend out of the storage cavity 224 of the lower seat section 221, so that the storage panel 223 is approximately perpendicular to the back of the lower seat section 221. With this configuration, the storage panel 223 can similarly serve as a headboard, limiting the length of the sleeper assembly in a flat position, so that shorter people can use the sleeper assembly more comfortably.

[0048] In some embodiments, the sleeper assembly includes a hinge mechanism (not shown), a seal 3, and a sound insulation element 4. The hinge mechanism is located between the seat cushion 21 and the backrest 22, and is used to control the rotation angle of the lower seat portion 221 and the upper seat portion 222. Specifically, the hinge structure includes a first hinge and a second hinge. The first hinge is connected to the seat cushion 21 and the lower seat portion 221, and the second hinge is connected to the lower seat portion 221 and the upper seat portion 222. Both the first and second hinges can be locked, fixing the seat cushion 21 and the lower seat portion 221, as well as the lower seat portion 221 and the upper seat portion 222, within a selected included angle.

[0049] The sealing element 3 and the sound insulation element 4 are abutted between the berth body 1 and the seat 2, and between the seat cushion 21 and the lower seat section 221. This arrangement prevents dust, debris, and other impurities from entering the gaps between the seat cushion 21 and the seat back 22, and between the berth body 1 and the seat 2. It also reduces noise transmission from these gaps to the berth body 1, thereby improving the comfort and quietness of the resting environment. The sealing element 3 can be made of materials such as rubber or plastic, and the sound insulation element 4 can be made of materials such as rubber or foam.

[0050] To improve the automation level of the sleeper assembly, the sleeper assembly also includes a motor that can be connected to a hinge mechanism to control the rotation of the hinge mechanism, so that the backrest 22 and the upper seat 222 can rotate automatically.

[0051] In some embodiments, the sleeper assembly includes a cushioning layer, which is laid at least on the back side of the seat back 22 and the upper side 11 of the sleeper. The cushioning layer may be made of materials such as leather or sponge, thereby improving the comfort of the sleeper assembly.

[0052] This application also provides a cockpit including the sleeper assembly as described above. The seat 2 is movable and adjustable relative to the sleeper body 1. Specifically, when people are driving, the seat 2 is movable and adjustable to move away from the sleeper body 1. When people are preparing to rest, the seat 2 is movable and adjustable to move closer to the sleeper body 1.

[0053] This application also provides a vehicle including a cockpit as described above.

[0054] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all 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.
