[0043] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] In the prior art, some vehicles are provided with berths for the passengers to rest. In order to improve the utilization rate of the space in the vehicle and reduce the occupation of the lower space in the vehicle, the berths can be arranged in the upper space in the vehicle to form upper berths.

[0045] The upper berth includes a berth board for people to lie down. One edge of the berth board is fixedly connected to the inner wall of the vehicle, and the other side is connected to the roof of the vehicle through a suspension rod, so that the berth board is fixed in the upper space of the vehicle. People in the vehicle usually use the seat armrests in the vehicle or the lower berth arranged under the upper berth to climb into the berth, which is inconvenient to operate and poses a safety hazard. In order to facilitate people in the vehicle to climb into the berth, a ladder is also provided on the upper berth.

[0046] One end of the ladder is connected to the upper berth, and the other end extends downward and abuts or overlaps with the vehicle floor below the upper berth or other fixed structures such as the lower berth arranged below the upper berth to ensure the stability of the ladder. As a result, the existing berth ladder occupies more space in the vehicle, resulting in low space utilization in the vehicle.

[0047] In order to overcome the defects in the prior art, the present application provides an upper berth and a vehicle, wherein the upper berth is provided with a accommodating cavity, and a ladder assembly is slidably arranged in the accommodating cavity. When the ladder assembly is extended out of the accommodating cavity, it can be flipped to a preset angle relative to the berth board. When the ladder assembly is retracted into the accommodating cavity, it does not occupy space outside the berth board. In this way, the space occupied by the ladder assembly in the vehicle can be reduced, thereby improving the utilization rate of the space in the vehicle.

[0048] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0049] Figure 1 A schematic diagram of the structure of the ladder assembly of the upper berth provided in an embodiment of the present application in the deployed position; Figure 2 A schematic structural diagram of the ladder assembly of the upper berth provided in an embodiment of the present application in the storage position.

[0050] On the one hand, the present application provides an embodiment of an upper berth, the upper berth is used in a vehicle, such as Figure 1 and Figure 2 As shown, the upper berth includes a berth board 100 and a ladder assembly 200. The berth board 100 is used to be fixedly connected to the inner wall of the vehicle. The berth board 100 has a receiving cavity 110 therein. The receiving cavity 110 has an opening on one side away from the inner wall.

[0051] The ladder assembly 200 is constructed to have a storage position and an extended position. When in the storage position, it is inserted into the accommodating cavity 110 through the opening. When in the extended position, it is located outside the accommodating cavity 110 and abuts against the berth board 100 to form a preset angle.

[0052] It is understandable that one side of the sleeping board 100 along the length direction is directly fixedly connected to the inner side wall of the vehicle. Specifically, when the upper sleeping board is applied to a freight vehicle such as a heavy truck, it can be connected to the inner side wall of the cab, and when the upper sleeping board is applied to a passenger vehicle, it can be connected to the inner side wall of the passenger seat behind the cab, and this application does not limit this. The side of the sleeping board 100 away from the inner side wall is provided with a suspension rod 120, and is connected to the top of the space in the vehicle through the suspension rod 120 to achieve stable installation of the sleeping board 100. After installation, a certain interval is formed between the sleeping board 100 and the floor of the vehicle, and a mattress can be laid on the sleeping board 100 to enhance the user experience of the upper sleeping board.

[0053] A accommodating cavity 110 is provided on the side of the berth board 100 facing away from the inner wall. The accommodating cavity 110 is also provided with an opening on the side facing away from the inner wall. The ladder assembly 200 is inserted into the accommodating cavity 110 through the opening. In this way, the specific sliding position of the ladder assembly 200 relative to the accommodating cavity 110 can be adjusted to form a commonly used storage position and deployment position of the ladder assembly 200.

[0054] It is set that the end of the ladder assembly 200 that first enters the accommodating chamber 110 through the opening is the insertion end 2121. Taking the insertion end 2121 as an example, when the ladder assembly 200 is in the storage position, the insertion end 2121 is located at the bottom of the side of the accommodating chamber 110 away from the opening, and the remaining parts of the ladder assembly 200 are all located in the accommodating chamber 110 driven by the insertion end 2121, and do not occupy the space outside the berth board 100; when the ladder assembly 200 is in the deployed position, the insertion end 2121 is on the opening side of the accommodating chamber 110, and the remaining parts of the ladder assembly 200 are all located outside the accommodating chamber 110, so that a preset angle α can be formed between the ladder assembly 200 and the berth board 100 by adjusting the posture of the ladder assembly 200 for people to climb.

[0055] Therefore, the upper berth provided in the embodiment of the present application is provided with a receiving chamber 110 in the berth board 100, and a ladder assembly 200 inserted in the receiving chamber 110 is provided. In this way, when it is necessary to climb onto the upper berth through the ladder assembly 200, the ladder assembly 200 can be taken out of the receiving chamber 110, and the ladder assembly 200 and the berth board 100 form a preset angle α that is convenient for people to climb, so that the ladder assembly 200 is in an unfolded position for people in the vehicle to climb; and when the ladder assembly 200 is not in use, the ladder assembly 200 can be completely stored in the receiving chamber 110 through the opening of the receiving chamber, so that the ladder assembly 200 is in a storage position, avoiding the ladder assembly 200 from occupying the space in the vehicle. In this way, the space occupied by the ladder assembly 200 in the vehicle is reduced, and the utilization rate of the space in the vehicle is improved.

[0056] Figure 3 A schematic diagram of the internal structure of the upper berth when the ladder assembly provided in an embodiment of the present application is in the storage position; Figure 4 A schematic diagram of the partial structure of the locking assembly of the upper berth provided in an embodiment of the present application.

[0057] like Figures 1 to 4 As shown, in some embodiments, a locking assembly 300 is further included, and the locking assembly is disposed on the ladder assembly 200;

[0058] The locking assembly 300 is configured to at least partially extend into the accommodating cavity 110 and engage with the sleeping board 100 when the ladder assembly 200 is in the storage position.

[0059] It is understandable that by providing the locking assembly 300 on the ladder assembly 200, when the ladder assembly 200 is in the accommodating chamber 110, the locking assembly 300 can stably restrict the ladder assembly 200 in the accommodating chamber 110, thereby preventing the ladder assembly 200 from extending by itself during the driving of the vehicle, thereby improving the safety protection performance of the upper berth. When the ladder assembly 200 needs to be removed, the locking assembly 300 can also be unlocked to cancel the restriction of the locking assembly 300 on the ladder assembly 200.

[0060] To facilitate the unlocking operation of the locking assembly 300 , the locking assembly 300 may be disposed at an end of the ladder assembly 200 away from the insertion end 2121 , so that the locking assembly 300 is close to the opening when the ladder assembly 200 is in the storage position.

[0061] Furthermore, in some embodiments, Figure 1 and Figure 3 As shown, the ladder assembly 200 includes a ladder body and two sliding shafts 211 arranged at the same end of the ladder body, the inner wall of the accommodating cavity 110 is provided with a sliding rail 111 corresponding to the sliding shaft 211, the sliding shaft 211 is slidably connected to the sliding rail 111, and at least one of the sliding rail 111 and the ladder body is rotatably connected to the sliding shaft 211.

[0062] It is easy to understand that by arranging the slide rails 111 on both sides of the corresponding openings of the accommodating cavity 110, and arranging the slide shafts 211 matching the slide rails 111 on both sides of the ladder assembly 200, the relative sliding of the ladder assembly 200 in the accommodating cavity 110 can be easily achieved. In addition, by using the circumferentially smooth slide shaft 211 instead of the angular slider, it is also convenient to realize the swing of the ladder body relative to the sleeper board 100 when the ladder body is in the unfolded position by rotatably connecting the slide shaft 211 with at least one of the slide rails 111 and the ladder body, so that the ladder assembly 200 forms a preset angle with the sleeper board 100.

[0063] It should be noted that a stop structure (not shown) may be provided at both ends of the slide rail 111 to limit the movement of the slide shaft 211 and prevent the slide shaft 211 from falling out.

[0064] In order to avoid the ladder assembly 200 occupying the space directly below the berth board 100 and to facilitate people to get on the berth, the preset angle α can be set to any value in the range of 90°≤α≤110°, for example, the preset angle α can be set to 100°.

[0065] Specifically, a sliding shaft 211 can be arranged to be fixedly connected to the ladder body and rotatably connected to the slide rail 111, so as to ensure the connection stability between the sliding shaft 211 and the ladder body and enable the sliding shaft 211 to slide and rotate relative to the slide rail 111 at the same time, thereby improving the operational efficiency of the ladder assembly 200 in switching between the deployed position and the stored position.

[0066] In other embodiments, the stopping structure may not be provided at the end of the slide rail 111 that opens toward the accommodating chamber 110, so that the ladder assembly 200 can be detachably connected to the berth board 100 and the accommodating chamber 110. In this way, when the ladder assembly 200 is switched from the storage position to the unfolded position, the ladder assembly 200 can be completely taken out of the accommodating chamber 110, and then the ladder assembly 200 can be adjusted to a preset angle α, and then the ladder assembly 200 and the berth board 100 can be overlapped at the preset angle α. After the ladder assembly 200 is used, the ladder assembly 200 can be removed again, slidably inserted into the accommodating chamber 110, and locked by the locking assembly 300. The present application does not impose any restrictions on this.

[0067] like Figure 1 and Figure 3 As shown, the ladder body includes a first ladder group 210, the first ladder group 210 includes a first step rod 213 and two first ladder rods 212 arranged at intervals, the first step rod 213 is located between the two first ladder rods 212, and the sliding shafts 211 are respectively arranged at the ends of the first ladder rods 212 away from the first step rods 213;

[0068] The first ladder group 210 is configured to abut against the sleeping board 100 to form a preset angle when in the deployed position, and to be inserted into the accommodating cavity 110 when in the stored position.

[0069] It can be understood that the two first ladder bars 212 are arranged at intervals, and the specific interval size is adapted to the size of the accommodating cavity 110 along the length direction of the bunk board 100, so that the sliding shaft 211 can be set on both sides of the ends of the two first ladder bars 212 respectively facing the insertion end 2121, and the first pedal 213 can be set between the two first ladder bars 212.

[0070] Specifically, both ends of the first tread bar 213 are connected to the opposite side of the first ladder bar 212 by bolts, or other fixed connection methods such as welding are adopted to ensure that the first tread bar 213 is reliably connected to the first ladder bar 212.

[0071] In addition, the number of the first step rod 213 is at least one, and it can be set at the end of the first ladder rod 212 away from the sliding shaft 211, or two or more can be set according to the length of the first ladder rod 212 and the required stepping distance, which is not limited in the present application.

[0072] Figure 5 A partial structural schematic diagram of the inter-hook structure of the ladder assembly provided in an embodiment of the present application.

[0073] Further, such as Figures 1 to 3 and Figure 5 As shown, the ladder body also includes a second ladder group 220, and the second ladder group 220 includes a second step rod 222 and two second ladder rods 221, one end of the second ladder rod 221 is respectively slidably inserted in the first ladder rod 212, and one side of the second step rod 222 is connected to the other ends of the two second ladder rods 221;

[0074] The second ladder group 220 is configured such that when in the deployed position, the second ladder rod 221 extends out of the first ladder rod 212, and when in the stored position, the second ladder rod 221 is retracted to the first ladder rod 212, the second step rod 222 closes the opening on the side away from the accommodating cavity 110, and smoothly transitions to the side of the berth board 100 opposite to the inner wall.

[0075] By inserting the second ladder group 220 at the end of the first ladder group 210 away from the sliding shaft 211, a retractable ladder assembly 200 can be formed by the first ladder group 210 and the second ladder group 220, so that when the ladder assembly 200 is in the deployed position, the second ladder rod 221 extends relative to the first ladder rod 212, and the ladder assembly 200 is extended as a whole; when the ladder assembly 200 is in the stored position, the second ladder rod 221 is retracted relative to the first ladder rod 212, and the ladder assembly 200 is shortened as a whole, which is more convenient to use and does not interfere with storage.

[0076] In addition, one side of the second step rod 222 is connected to the end of the second ladder rod 221 by bolts, or other fixed connection methods such as welding are adopted to ensure that the second step rod 222 and the second ladder rod 221 are reliably connected.

[0077] Compared with the setting form of the first pedal 213, the two ends of the second pedal 222 are respectively extended to the two sides of the second ladder rod 221, so that the second pedal 222 serves as a blocking structure of the ladder body, so that when the ladder assembly 200 is in the storage position, the opening of the accommodating cavity 110 is closed by the second pedal 222, and other structures of the ladder assembly 200 located in the accommodating cavity 110 are shielded.

[0078] In addition, a second pedal 222 is arranged on a side facing away from the accommodating cavity 110 to match the outer trim of the berth board 100. The second pedal 222 can close the opening of the accommodating cavity 110 and shield other structures of the ladder assembly 200, thereby further achieving a hidden storage effect when the ladder assembly 200 is in the storage position. This can reduce the space occupied by the ladder assembly 200 in the vehicle and improve the user experience of the ladder assembly 200.

[0079] In some embodiments, at least one of the first pedal 213 and the second pedal 222 is further provided with an anti-slip pad layer on one side facing the insertion end 2121 to further improve the user experience of the ladder assembly 200 and improve the safety protection effect of the ladder assembly 200.

[0080] Additional stepping rods may be provided between the two ends of the second ladder rod 221 according to the specific extension length of the second ladder rod 221 and the required stepping interval to facilitate climbing, and the present application does not impose any limitation on this.

[0081] Further, such as Figure 5 As shown, in some embodiments, the ladder body also includes an interlocking structure, which includes a first hook 215, a second hook 224 and a pad 225. The first hook 215 is adapted to the second hook 224. The first hook 215 is arranged at one end of the first ladder rod 212 facing the second ladder rod 221, and the second hook 224 is arranged at one end of the second ladder rod 221 facing the first ladder rod 212, and abuts against the first hook 215. The pad 225 is located between the first hook 215 and the second hook 224.

[0082] The two second ladder rods 221 of the second ladder group 220 are respectively slidably inserted into the first ladder rod 212, and a folded edge that is folded inward twice is set on the first ladder rod 212 as a first hook 215, and a folded edge that is folded outward twice is set on the second ladder rod 221 as a second hook 224. The first hook 215 and the second hook 224 are adapted to each other, and when the second ladder rod 221 extends out of the first ladder rod 212, they are hooked and abutted to prevent the second ladder rod 221 from falling out, thereby ensuring that the structure of the ladder assembly 200 is stable and reliable. When the second ladder rod 221 is retracted into the first ladder rod 212, the first hook 215 and the second hook 224 are disengaged from the abutment.

[0083] Thus, a cushion block 225 may be provided between the first hook 215 and the second hook 224 to cushion the impact force when the first hook 215 and the second hook 224 are hooked together, thereby reducing noise and extending the service life of the ladder assembly 200.

[0085] In addition, in some embodiments, the first ladder group 210 also includes abutment 214, which is correspondingly arranged at the end of the first ladder rod 212 having the sliding shaft 211, and the first ladder rod 212 has a slot 2122 adapted to the abutment 214, and the abutment 214 abuts against the slot 2122 so that the first ladder group 210 forms a preset angle with the berth board 100.

[0086] In this way, the abutment member 214 and the accommodating cavity 110 can be clamped relatively tightly and cannot rotate relative to each other. When the first ladder rod 212 rotates, the slot 2122 of the first ladder rod 212 abuts against the abutment member 214, thereby keeping the ladder body at a preset angle. The preset angle can be adjusted by adjusting the depth of the slot 2122 or the position relative to the first ladder rod 212.

[0087] Specifically, the slot 2122 can be set as a U-shaped slot, and the abutment member 214 is a protruding rib adapted to the slot 2122, and the protruding rib is inclined toward one side of the slot 2122 to improve the abutment effect between the slot 2122 and the abutment member 214.

[0088] In some other embodiments, Figures 2 to 4 As shown, the locking assembly 300 includes a pressing member 310, at least one pushing member 320 and a locking member 330 corresponding to the pushing member 320, the second pedal 222 has a mounting cavity 223, the pressing member 310 is inserted on the second pedal 222 and at least partially located in the mounting cavity 223, the pushing member 320 is connected to the pressing member 310, the pushing member 320 has a first inclined surface 321, the locking member 330 has a second inclined surface 331 adapted to the first inclined surface 321, the first inclined surface 321 and the second inclined surface 331 are slidably connected, at least part of the locking member 330 is located outside the mounting cavity 223, and is clamped with the sleeping board 100;

[0089] The pressing member 310 is configured to, when pressed by an external force, drive the pushing member 320 to move relative to the mounting cavity 223 , and drive the second inclined surface 331 to slide relative to the first inclined surface 321 , so that the locking member 330 moves to disengage from the sleeping board 100 .

[0090] It can be understood that, in a specific implementation, two pushing members 320 and two locking members 330 respectively connected to the pushing members 320 can be symmetrically arranged on both sides of the pressing member 310, so that the actions of the locking members 330 on both sides can be controlled simultaneously by the pressing member 310, thereby improving the operating efficiency, and enabling the locking members 330 to be engaged with the berth board 100 from both sides, thereby improving the stability of the engagement and ensuring the locking effect of the locking assembly 300.

[0091] The pressing member 310 is movably inserted on the second pedal 222 and partially located in the installation cavity 223, and the pushing member 320 is fixedly connected to the pressing member 310, and symmetrical first inclined surfaces 321 are respectively arranged on the pushing member 320, and one end of the two locking members 330 respectively has a second inclined surface 331 matching the first inclined surface 321, and the first inclined surface 321 is slidably connected to the second inclined surface 331, and the other end of the two locking members 330 extends out of the installation cavity 223 to be clamped with the outer decorative panel of the bunk board 100 outside the installation cavity 223.

[0092] When external force is applied to the pressing member 310, the pushing member 320 will move toward the inside of the installation cavity 223 driven by the pressing member 310, and the first inclined surface 321 on the pushing member 320 and the second inclined surface 331 on the locking member 330 will interact with each other, so that the two locking members 330 are driven by the movement of the second inclined surface 331 to approach each other, so that the parts of the two locking members 330 that are engaged with the sleeper board 100 are disengaged from the sleeper board 100 along the moving direction of the locking members 330, and even retracted into the installation cavity 223.

[0093] In other embodiments, only one pushing member 320 connected to the pressing member 310 may be provided, and one locking member 330 may be provided connected to the pushing member 320 , and the direction of the locking member 330 may be specifically adjusted to provide a better locking effect.

[0094] Further, such as Figure 4 As shown, the locking assembly 300 also includes a first reset member 340 and a second reset member 350. The two ends of the first reset member 340 respectively abut against the inner wall of the pressing member 310 and the mounting cavity 223, and the two ends of the second reset member 350 respectively abut against the inner wall of the locking member 330 and the mounting cavity 223, so as to respectively drive the pressing member 310 and the locking member 330 to reset when the external force is removed.

[0095] The first return member 340 and the second return member 350 are both coil springs. The first return member 340 abuts against the inner wall of the pressing member 310 and the mounting cavity 223 along the moving direction of the pressing member 310, and the second return member 350 abuts against the inner wall of the locking member 330 and the mounting cavity 223 along the moving direction of the locking member 330.

[0096] In this way, when the pressing member 310 is pressed and moved by an external force, and the locking member 330 is driven to move by the pushing member 320, the first restoring member 340 and the second restoring member 350 are compressed and deformed. After the external force on the pressing member 310 is removed, the first restoring member 340 recovers its deformation and drives the pressing member 310 to move in the opposite direction of the external force, and the second restoring member 350 also recovers its deformation and drives the two locking members 330 to move away from each other, so that at least part of the locking member 330 extends out of the installation cavity 223 to be engaged with the sleeping board 100 again.
