DETAILED DESCRIPTION

[0029] In order to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0030] Referring to Figures 1 to 7 The embodiments of the present application provide a sleeping berth protection device and a vehicle thereof, which can solve the problem of inconvenient use and storage of the current protection device in the related art.

[0031] In a first aspect, the embodiments of the present application provide a sleeping berth protection device, which comprises a mounting beam 7, a longitudinal beam 2, an upper cross beam 1 and a locking unit 3, the mounting beam 7 is fixed on a sleeping berth base; the longitudinal beam 2 is arranged on the mounting beam 7, the longitudinal beam 2 has a horizontal state and a vertical state; the longitudinal beam 2 is rotationally connected with the upper cross beam 1; the locking unit 3 is connected with the longitudinal beam 2, and the locking unit 3 has a first position and a second position; wherein the locking unit 3 is configured to: when the longitudinal beam 2 is in the vertical state, when the locking unit 3 is in the first position, the locking unit 3 is used to lock the longitudinal beam 2, so that the longitudinal beam 2 remains in the vertical state; when the locking unit 3 is in the second position, the locking unit 3 is used to unlock the longitudinal beam 2, so that the longitudinal beam 2 is adjusted from the vertical state to the horizontal state.

[0032] In the present application, when the protection device is not used, the longitudinal beam 2 is arranged horizontally, which does not affect the normal sitting and resting of personnel on the sleeping berth; when the protection device is used, the protection device is raised, the longitudinal beam 2 is in the vertical state, and the longitudinal beam 2 is locked by the locking unit 3, so that the longitudinal beam 2 is flush with the height of the personnel, thereby preventing the personnel from falling.

[0033] Referring to Figure 1 At this time, the longitudinal beam 2 is in the vertical state, referring to Figure 7 At this time, the longitudinal beam 2 is in the horizontal state. Generally, in order to ensure the stability of the protection device in the vertical state, a plurality of longitudinal beams 2 are arranged with gaps to provide collaborative support. A mounting groove 70 is formed on the mounting beam 7, so that the longitudinal beam 2 is accommodated in the mounting groove 70 when the longitudinal beam 2 is in the horizontal state.

[0034] On the basis of the above-mentioned embodiments, in the present embodiment, the locking unit 3 is arranged in the upper cross beam 1; the sleeping berth protection device further comprises a button unit 4, the button unit 4 is connected with the upper cross beam 1 and located on one side of the locking unit 3, and the button unit 4 is used to switch the locking unit 3 between the first position and the second position.

[0035] In this embodiment, through the cooperation of the structure provided on the button unit 4, the locking unit 3 and the longitudinal beam 2, the longitudinal beam 2 can be unlocked or locked by the locking unit 3 through the operation of the button unit 4.

[0036] Specifically, the locking unit 3 includes a locking piece 30 and an elastic piece 31. The locking piece 30 is provided with a slot in the middle for the longitudinal beam 2 to pass through. One end of the elastic piece 31 is connected with the locking piece 30, and the other end is connected with the inner wall of the upper cross beam 1.

[0037] When the locking piece 30 is in the first position, the top end of the longitudinal beam 2 passes through the top end of the slot. When the movable end is in the second position, the locking piece 30 is above the longitudinal beam 2. The button unit 4 is used to drive the locking piece 30 to switch between the first position and the second position.

[0038] The locking piece 30 is arranged in the internal space of the upper cross beam 1, which not only ensures the compactness of the structure, but also enables flexible position adjustment inside the upper cross beam 1. In this embodiment, in order to further enhance the flexibility and practicality of the structure, a rotating connection mode between the longitudinal beam 2 and the mounting beam 7 is designed. This setting mode enables the longitudinal beam 2 to freely switch between the vertical state and the horizontal state through a simple rotating action, thereby meeting the needs of different use scenarios.

[0039] In order to realize the stable conversion and locking of the longitudinal beam 2 between the two states, the locking unit 3 is provided. The locking unit 3 is arranged on the rotating path of the longitudinal beam 2, and through the adjustment of the locking unit 3 by the button unit 4, the movement of the longitudinal beam 2 can be intervened. When the longitudinal beam 2 is in the vertical state and the locking piece 30 is in the first position, the further rotation of the longitudinal beam 2 can be blocked, thereby effectively realizing the purpose of keeping the longitudinal beam 2 in the vertical state. This design not only improves the stability and safety of the structure, but also brings users a more convenient and efficient use experience.

[0040] In this embodiment, the slot is arranged in the middle of the locking piece 30. When the locking piece 30 is in the first position, the longitudinal beam 2 passes through the slot, so that the four wall surfaces of the locking piece 30 intervene and limit the movement of the longitudinal beam 2.

[0041] On the basis of the above embodiment, in this embodiment, the locking piece 30 has multiple ways to switch between the first position and the second position.

[0042] In some possible embodiments, the locking piece 30 is arranged to slide up and down on the inner wall surface of the upper cross beam 1, and the sliding track is smooth and smooth. When the locking piece 30 slides downward along the inner wall surface of the upper cross beam 1 to the limit position, that is, the first position, the longitudinal beam 2 can be precisely arranged in the inner part of the hollow groove, so that the wall surface of the locking piece 30 can intervene and limit the movement of the longitudinal beam 2. On the contrary, when the locking piece 30 slides upward along the inner wall surface to the other limit position, that is, the second position, the hollow groove is completely away from the top end of the longitudinal beam 2, and the longitudinal beam 2 is no longer limited by the locking piece 30, so that the position of the longitudinal beam 2 can be adjusted freely or related operations can be performed.

[0043] In the embodiment, the elastic piece 31 is arranged between the locking piece 30 and the inner wall surface of the upper cross beam 1, and the elastic piece 31 is used to drive and reset. When the locking piece 30 is moved from the first position for limiting the longitudinal beam 2 to the second position for releasing the longitudinal beam 2 in response to the operation, if the longitudinal beam 2 needs to be adjusted in angle at this time, for example, the longitudinal beam 2 is flexibly converted from the vertical state to the horizontal state, after the adjustment is completed, the button unit 4 for controlling the locking piece 30 is released, and the release action can immediately trigger the rebound mechanism of the elastic piece 31. The elastic piece 31 automatically and quickly adjusts the locking piece 30 from the second position in the released state back to the first position in the locked state by relying on the elastic potential energy accumulated by itself, so as to ensure the stability and safety of the whole system.

[0044] In the embodiment, the button unit 4 can be arranged at the top end of the upper cross beam 1.

[0045] In other possible embodiments, referring to FIG. 2, the button unit 4 is arranged on one side of the upper cross beam 1. Figures 2-4

[0046] In the embodiment, one end of the locking piece 30 is a rotating end and is rotationally connected with the inner wall surface of the upper cross beam 1, and the other end is a movable end and has a first position and a second position. One end of the elastic piece 31 is connected with the movable end, and the other end is rotationally connected with the inner wall surface of the upper cross beam 1. When the locking piece 30 is located at the first position, the top end of the longitudinal beam 2 is located between the rotating end and the movable end. When the movable end is located at the second position, the locking piece 30 is located above the longitudinal beam 2.

[0047] Specifically, referring to FIG. 3, the locking piece 30 is arranged to slide up and down on the inner wall surface of the upper cross beam 1, and the sliding track is smooth and smooth. When the locking piece 30 slides downward along the inner wall surface of the upper cross beam 1 to the limit position, that is, the first position, the longitudinal beam 2 can be precisely arranged in the inner part of the hollow groove, so that the wall surface of the locking piece 30 can intervene and limit the movement of the longitudinal beam 2. On the contrary, when the locking piece 30 slides upward along the inner wall surface to the other limit position, that is, the second position, the hollow groove is completely away from the top end of the longitudinal beam 2, and the longitudinal beam 2 is no longer limited by the locking piece 30, so that the position of the longitudinal beam 2 can be adjusted freely or related operations can be performed. Figure 4 ​As shown, at this time, the locking member 30 is located at its designed first position, and the top end of the longitudinal beam 2 just passes through the top end of the hollow groove, forming a locked state. To unlock this state, the button unit 4 is pushed to one side of the locking member 30, which precisely acts on the movable end of the locking member 30, so that the movable end of the locking member 30 is gradually lifted. With the continuous force of the button unit 4, the movable end is lifted until it reaches its designed maximum position, at which time the movable end has been successfully transferred from the first position to the second position. In this state, the locking connection between the longitudinal beam 2 and the hollow groove is released, and the longitudinal beam 2 is thus released from the hollow groove and loses the limiting effect of the locking member 30, so that the longitudinal beam 2 can freely adjust its position in space or perform other related operations, greatly improving the flexibility and practicality of the system.

[0048] In this embodiment, one end of the elastic member 31 is connected to the movable end of the locking member 30, and the other end is rotationally connected to the inner wall of the upper cross beam 1. In addition, in order to optimize its working efficiency, the elastic member 31 is arranged in an inclined posture. When the locking member 30 is successfully moved from the first position limiting the movement of the longitudinal beam 2 to the second position releasing the longitudinal beam 2 in response to an external operation instruction, if the longitudinal beam 2 needs to be adjusted in angle at this time, such as being converted from a vertical state to a horizontal state, then after completing this angle conversion, the button unit 4 controlling the locking member 30 is released. After this release action is completed, the elastic member 31 triggers the rebound mechanism inside. The elastic member 31 automatically pulls the locking member 30 back from the released second position to the first position by virtue of its long-term accumulated elastic potential energy, thereby ensuring the stability and safety of the entire device after any operation, embodying the ingenuity and practicality of the design.

[0049] The above embodiment is only one of the possible implementations of the present application, and the present application is not limited thereto.

[0050] For example, the button unit 4 is arranged on one side of the upper cross beam 1, one end of the locking member 30 is a rotating end rotationally connected to the inner wall of the upper cross beam 1, and the other end is a movable end.

[0051] On the basis of the above embodiment, in this embodiment, the elastic member 31 includes a first spring 310 and a fixed rod 311, one end of the first spring 310 is fixed to the movable end of the locking member 30, one end of the first spring 310 is fixed to the fixed rod 311, and the first spring 310 is arranged in an inclined manner, and the fixed rod 311 is rotationally connected to the inner wall of the upper cross beam 1.

[0052] The locking piece 30 comprises two stamping sheets 300 and two limiting rods 301, the two limiting rods 301 are fixed on the two sides of the two stamping sheets 300, the two stamping sheets 300 and the two limiting rods 301 form a square structure, and an empty slot for limiting the rotation of the longitudinal beam 2 is formed between the two stamping sheets 300 and the two limiting rods 301. One limiting rod 301 is rotationally connected with the inner wall of the upper cross beam 1.

[0053] Further, the top end of the longitudinal beam 2 is provided with a limiting slot 20, when the locking unit 3 is located at the first position, the locking unit 3 is clamped in the limiting slot 20.

[0054] That is to say, when the other limiting rod 301 is located at the designed first position, the limiting rod 301 will be clamped in the internal space of the limiting slot 20 exactly and stably, this design not only enhances the stability of the structure, but also further limits the activity range of the longitudinal beam 2 effectively, ensuring the accuracy and safety of the whole device during operation.

[0055] On the basis of the above embodiment, in the present embodiment, the button unit 4 comprises a side cover 40, a button switch 41 and a second spring 42, the side cover 40 is fixed on one side of the upper cross beam 1, the button switch 41 is movably connected in the side cover 40, one end of the button switch 41 is provided with a pushing plate 43, the top end of the pushing plate 43 is beveled, the pushing plate 43 penetrates the side cover 40, and the pushing plate 43 moves along the moving path to drive the locking unit 3 to switch between the first position and the second position, one end of the second spring 42 is connected with the button switch 41, and the other end is connected with the side cover 40.

[0056] Specifically, the side cover 40 and the upper cross beam 1 are fixed together to form a stable and reliable structure. A containing groove is opened in the side cover 40, the size and shape of the containing groove are accurately calculated and designed for the button switch 41, so that the button switch 41 can slide smoothly in the containing groove. In the present embodiment, in order to further optimize the structure, a through groove needs to be opened on the wall surface of the side cover 40, the through groove is in communication with the inside of the containing groove. When the button switch 41 slides in the containing groove, the pushing plate 43 can penetrate the through groove and accurately push the movable end of the locking piece 30, so as to realize the corresponding locking or unlocking function.

[0057] It should be noted that a through slot 21 is opened at the top end of the longitudinal beam 2, which can also be penetrated by the pushing plate 43. The through slot 21 is opened to avoid the interference of the pushing plate 43 with the rotation of the longitudinal beam 2 after the movable end of the locking piece 30 is pushed to the second position.

[0058] A second spring 42 is fixedly connected between the button switch 41 and the inner wall of the accommodating groove. When the button switch 41 is moved to the side of the locking piece 30 under the action of external force, the second spring 42 is gradually compressed to store elastic potential energy. When the external force disappears, i.e., the button switch 41 is released, the second spring 42 rapidly rebounds by using the stored elastic potential energy to push the button switch 41 to return to the initial position, thereby ensuring the stability and reliability of the operation.

[0059] On the basis of the above-mentioned embodiment, in the present embodiment, a plurality of longitudinal beams 2 are arranged on the mounting beam 7 at intervals, at least one longitudinal beam 2 is provided with a speed reduction unit 5, and the speed reduction unit 5 comprises a pneumatic support rod 50, one end of the pneumatic support rod 50 being rotatably connected with the upper cross beam 1.

[0060] Referring to Figure 4 The pneumatic support rod 50 is arranged on another longitudinal beam 2, one end of the pneumatic support rod 50 being rotatably connected with the upper cross beam 1 and the other end being rotatably connected with the longitudinal beam 2. The pneumatic support rod 50 is stretched along with the movement of the longitudinal beam 2 and the upper cross beam 1, thereby preventing the opening or closing speed from being too fast, and ensuring the stability and safety of the entire operation process.

[0061] On the basis of the above-mentioned embodiment, in the present embodiment, a protective seat 8 is arranged on the outer surface of the upper cross beam 1, and a mounting groove 70 for accommodating the longitudinal beam 2 is arranged on the mounting beam 7.

[0062] In the present embodiment, the upper cross beam 1 can be preferably made of high-strength punched iron plate. This material not only has excellent rigidity and stability, can effectively play a key role in fixing the locking unit 3, the button unit 4 and the protective seat 8, but also ensures the structural integrity of the entire protective device. At the same time, as the main bearing structure of the protective device, the upper cross beam 1 needs to be strictly considered when selecting the material, so as to ensure that even if the user steps on the protective device in the sleeping state, it can withstand the corresponding pressure, thereby ensuring that the protective device will not be damaged or deformed, maintaining its long-term reliability and safety.

[0063] The protective seat 8 comprises a top seat 80 and a protective cover 81. The top seat 80 is fixed to the upper cross beam 1 to shield the internal structure and install the protective cover 81. The protective cover 81 is installed on the surface of the top seat 80 and is made of soft foam material, which directly contacts the user's body to prevent the user from being injured by contacting hard objects and plays a protective role for the member.

[0064] Further, a decorative cover 6 is arranged on one side of the upper cross beam 1 and on both sides of the mounting beam 7. The decorative cover 6 shields the internal structure to ensure the appearance.

[0065] In summary, when the protection device is not used, it is under the front lower part of the sleeping pad and does not affect the normal sitting and resting of the personnel on the sleeping pad. When used, the protection device is raised to be level with the height of the personnel, thereby preventing the personnel from falling.

[0066] The sleeping pad protection device is covered with soft foam and leather, thereby having a buffering effect and being highly protective to the personnel.

[0067] Since the commercial vehicle has upper and lower sleeping pads, the upper sleeping pad is located at a high position from the ground, and the personnel has difficulty in getting on the upper sleeping pad. Therefore, the sleeping pad protection device is designed to be raised to provide a stepping surface for the personnel to get on the upper sleeping pad.

[0068] The protection device is designed with a hidden locking button, which is simple in appearance and convenient to operate.

[0069] In a second aspect, the embodiments of the present application provide a vehicle comprising the sleeping pad protection device provided in any of the above embodiments of the present application.

[0070] In the present application, when the protection device is not used, the longitudinal beam 2 is horizontally arranged, which does not affect the normal sitting and resting of the personnel on the sleeping pad. When used, the protection device is raised to make the longitudinal beam 2 in a vertical state, and the longitudinal beam 2 is locked by the locking unit 3, so that the longitudinal beam 2 is level with the height of the personnel, thereby preventing the personnel from falling.

[0071] In some embodiments, the sleeping pad protection device comprises a mounting beam 7, a longitudinal beam 2, an upper cross beam 1 and a locking unit 3. The mounting beam 7 is fixed to the sleeping pad base. The longitudinal beam 2 is arranged on the mounting beam 7, and the longitudinal beam 2 has a horizontal state and a vertical state. The top end of the longitudinal beam 2 is rotationally connected with the upper cross beam 1.

When the longitudinal beam 2 is in the vertical state, the locking unit 3 is configured to lock the longitudinal beam 2 when the locking unit 3 is in the first position, so that the longitudinal beam 2 remains in the vertical state. When the locking unit 3 is in the second position, the locking unit 3 is configured to unlock the longitudinal beam 2, so that the longitudinal beam 2 is adjusted from the vertical state to the horizontal state.

[0072] In some embodiments, the locking unit 3 is arranged inside the upper cross beam 1. The sleeping pad protection device further comprises a button unit 4, which is connected with the upper cross beam 1 and located on one side of the locking unit 3. The button unit 4 is used to switch the locking unit 3 between the first position and the second position.

[0073] In some embodiments, the locking unit 3 comprises a locking piece 30 and an elastic piece 31, the locking piece 30 is provided with a slot in the middle for the longitudinal beam 2 to pass through; one end of the elastic piece 31 is connected with the locking piece 30, and the other end is connected with the inner wall of the upper cross beam 1; when the locking piece 30 is in the first position, the top end of the longitudinal beam 2 passes through the top end of the slot, and when the movable end is in the second position, the locking piece 30 is above the longitudinal beam 2, and the button unit 4 is used to drive the locking piece 30 to switch between the first position and the second position.
