DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] See also Figures 1 to 7 The embodiment of the present application provides a berth protection device and a vehicle thereof, which can solve the problem of inconvenient use and storage of current protection devices in the related art.

[0031] In the first aspect, an embodiment of the present application provides a berth protection device, which includes: a mounting beam 7, a longitudinal beam 2, an upper cross beam 1 and a locking unit 3, wherein the mounting beam 7 is fixed on the berth 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 rotatably connected to the upper cross beam 1; the locking unit 3 is connected to the longitudinal beam 2, and the locking unit 3 has a first position and a second position; wherein the locking unit 3 is configured as follows: when the longitudinal beam 2 is in a vertical state, when the locking unit 3 is in the first position, the locking unit 3 is used to lock the longitudinal beam 2 to keep the longitudinal beam 2 in a vertical state; when the locking unit 3 is in the second position, the locking unit 3 is used to unlock the longitudinal beam 2 to adjust the longitudinal beam 2 from a vertical state to a horizontal state.

[0032] In the present application, when the protective device is not in use, the longitudinal beam 2 is set horizontally so as not to affect the normal sitting and resting of the personnel on the berth; when in use, the protective 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 flush with the height of the personnel, thereby preventing the personnel from falling.

[0033] See also Figure 1 As shown, the longitudinal beam 2 is in a vertical state at this time, see Figure 7 As shown, the longitudinal beam 2 is in a horizontal state. Generally, in order to ensure the stability of the protective device in a vertical state, multiple longitudinal beams 2 are arranged with gaps to provide collaborative support. A mounting groove 70 is provided on the mounting beam 7 so that the longitudinal beam 2 is accommodated inside the mounting groove 70 when it is in a horizontal state.

[0034] On the basis of the above embodiments, in this embodiment, the locking unit 3 is arranged inside the upper cross beam 1; the berth protection device also includes a button unit 4, which is connected to the upper cross beam 1 and is 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, by cooperating the button unit 4 , the locking unit 3 and the structures provided on the longitudinal beam 2 , the locking unit 3 can be controlled to unlock or lock the longitudinal beam 2 by operating the button unit 4 .

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

[0037] Among them, when the locking member 30 is in the first position, the top of the longitudinal beam 2 is penetrated by the top of an empty slot, and when the movable end is in the second position, the locking member 30 is located above the longitudinal beam 2, and the button unit 4 is used to drive the locking member 30 to switch between the first position and the second position.

[0038] The locking member 30 is arranged in the inner space of the upper cross beam 1, which not only ensures the compactness of the structure, but also enables the 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 rotation 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 rotation action, thereby meeting the needs of different usage scenarios.

[0039] In order to achieve stable conversion and locking of the longitudinal beam 2 between the two states, a locking unit 3 is provided. The locking unit 3 is arranged on the rotation path of the longitudinal beam 2. By adjusting 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 a vertical state and the locking member 30 is in the first position, the further rotation of the longitudinal beam 2 can be blocked, thereby effectively achieving the purpose of keeping the longitudinal beam 2 in a vertical state. This design not only improves the stability and safety of the structure, but also brings a more convenient and efficient use experience to users.

[0040] In this embodiment, an empty slot is provided in the middle of the locking member 30 . When the locking member 30 is located at the first position, the longitudinal beam 2 is penetrated by the empty slot so that the surrounding walls of the locking member 30 interfere with and limit the movement of the longitudinal beam 2 .

[0041] Based on the above embodiment, in this embodiment, there are multiple ways for the locking member 30 to switch between the first position and the second position:

[0042] In some possible embodiments, the locking member 30 is set to slide up and down on the inner wall surface of the upper cross beam 1, and its sliding track is stable and smooth. When the locking member 30 slides downward along the inner wall surface of the upper cross beam 1 to its extreme position, that is, the first position we call it, the longitudinal beam 2 can just accurately penetrate into the inside of the empty slot, so that the surrounding walls of the locking member 30 can intervene and limit the movement of the longitudinal beam 2. On the contrary, when the locking member 30 slides upward along the inner wall surface to its other extreme position, that is, the second position, the empty slot will be completely away from the top of the longitudinal beam 2. At this time, the longitudinal beam 2 loses the limiting effect of the locking member 30, so that its position can be freely adjusted or related operations can be performed.

[0043] In this embodiment, the elastic member 31 is arranged between the lock member 30 and the inner wall of the upper cross beam 1, and the function of the elastic member 31 is to drive and reset. When the lock member 30 responds to the operation and smoothly moves from the first position of restricting the longitudinal beam 2 to the second position of releasing the longitudinal beam 2, if the longitudinal beam 2 needs to be adjusted in angle at this time, such as flexibly converting the longitudinal beam 2 from a vertical state to a horizontal state, then after completing this adjustment, it is only necessary to release the button unit 4 controlling the lock member 30. This release action will immediately trigger the rebound mechanism of the elastic member 31, which automatically and quickly adjusts the lock member 30 from the second position of the released state back to the first position of the locked state by relying on its own accumulated elastic potential energy, thereby ensuring the stability and safety of the entire system.

[0044] In this embodiment, the button unit 4 can be arranged on the top of the upper beam 1 .

[0045] In some other possible embodiments, see Figure 2-Figure 4 As shown, the button unit 4 is arranged on one side of the upper cross beam 1.

[0046] In this embodiment, one end of the locking member 30 is a rotating end and is rotatably connected to the inner wall 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 member 31 is connected to the movable end, and the other end is rotatably connected to the inner wall of the upper cross beam 1; when the locking member 30 is in the first position, the top end of the longitudinal beam 2 is located between the rotating end and the movable end, and when the movable end is in the second position, the locking member 30 is located above the longitudinal beam 2.

[0047] For details, see Figure 4As shown, at this time, the locking member 30 is located in its designed first position, and the top of the longitudinal beam 2 just passes through the top of the empty slot, forming a locked state. When unlocking this state, the button unit 4 is pushed to one side of the locking member 30, and this action accurately 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 application of force by the button unit 4, the movable end is lifted until it reaches its designed maximum position. At this time, the movable end has been smoothly transferred from the first position to the second position. In this state, the locking connection between the longitudinal beam 2 and the empty slot is released, and the longitudinal beam 2 is thus freed from the constraint of the empty slot and loses the limiting effect of the locking member 30. In this way, the longitudinal beam 2 can freely adjust its position in the space, or perform other related operations, which greatly improves 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 connected to the inner wall of the upper crossbeam 1 by rotation. In addition, in order to optimize its working efficiency, the elastic member 31 is set to an inclined posture. When the locking member 30 responds to the external operation command and smoothly moves from the first position that restricts the movement of the longitudinal beam 2 to the second position that releases the longitudinal beam 2, if the longitudinal beam 2 needs to be adjusted in angle at this time, such as changing the longitudinal beam 2 from a vertical state to a horizontal state, then, it is only necessary to release the button unit 4 that controls the locking member 30 after completing this angle conversion. After the release action is completed, the rebound mechanism inside the elastic member 31 will be triggered. The elastic member 31 automatically pulls the locking member 30 back to the first position from the second position of the released state by virtue of its long-term accumulated elastic potential energy, thereby ensuring the stability and safety of the entire device after any operation, reflecting the exquisiteness and practicality of the design.

[0049] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

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

[0051] On the basis of the above embodiments, in this embodiment, the elastic member 31 includes a first spring 310 and a fixing rod 311, one end of the first spring 310 is fixed to the movable end of the locking member 30, and the other end is fixed to the fixing rod 311, and the first spring 310 is tilted, and the fixing rod 311 is rotatably connected to the inner wall of the upper beam 1.

[0052] The lock member 30 includes two stamping sheets 300 and two limiting rods 301, the two limiting rods 301 are fixed on both sides of the two stamping sheets 300, and 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. Among them, one limiting rod 301 is rotatably connected to the inner wall of the upper cross beam 1.

[0053] Furthermore, a limiting groove 20 is provided at the top end of the longitudinal beam 2 , and when the locking unit 3 is located at the first position, the locking unit 3 is engaged in the limiting groove 20 .

[0054] That is to say, when the other limit rod 301 is in its designed first position, the limit rod 301 will be just and firmly engaged in the internal space of the limit groove 20. This design not only enhances the stability of the structure, but also further effectively limits the range of movement of the longitudinal beam 2, thereby ensuring the accuracy and safety of the entire device during operation.

[0055] On the basis of the above embodiments, in this embodiment, the button unit 4 includes: a side cover 40, a button switch 41 and a second spring 42, the side cover 40 is fixed to one side of the upper beam 1; the button switch 41 is movably connected to the inside of the side cover 40, and a push plate 43 is provided at one end of the button switch 41, the top of the push plate 43 is an inclined surface, the push plate 43 passes through the side cover 40, and when the push plate 43 moves along the moving path, it is used 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 to the button switch 41, and the other end is connected to the side cover 40.

[0056] Specifically, the cross beams 1 on the side cover 40 are fixed together to form a stable and reliable structure. Inside the side cover 40, a receiving groove is provided. The size and shape of the receiving groove are precisely calculated and specially designed for the button switch 41 so that it can slide smoothly inside. In this embodiment, in order to further optimize the structure, a through groove is also required to be provided on the wall surface of the side cover 40, and the through groove is connected with the inside of the receiving groove. When the button switch 41 slides inside the receiving groove, the push plate 43 can pass through the through groove and accurately push the movable end of the locking member 30, thereby realizing the corresponding locking or unlocking function.

[0057] It should be noted that a through slot 21 is provided at the top of the longitudinal beam 2, through which the push plate 43 can pass. The purpose of providing the through slot 21 is to prevent the push plate 43 from pushing the movable end of the locking member 30 to the second position and interfering with the rotation of the longitudinal beam 2.

[0058] A second spring 42 is fixedly connected between the button switch 41 and the inner wall of the receiving groove. When the button switch 41 is moved toward the side of the locking member 30 by an external force, the second spring 42 will be gradually compressed and store elastic potential energy. When the external force disappears, that is, when the button switch 41 is released, the second spring 42 will rebound quickly using its stored elastic potential energy, pushing the button switch 41 back to its initial position, ensuring the stability and reliability of the operation.

[0059] On the basis of the above embodiments, in this embodiment, a plurality of longitudinal beams 2 are arranged at intervals on the mounting beam 7, and a deceleration unit 5 is arranged on at least one longitudinal beam 2. The deceleration unit 5 includes a pneumatic strut 50, and one end of the pneumatic strut 50 is rotatably connected to the upper cross beam 1.

[0060] See also Figure 4 As shown, the pneumatic strut 50 is arranged on another longitudinal beam 2, one end of the pneumatic strut 50 is rotatably connected to the upper cross beam 1, and the other end is rotatably connected to the longitudinal beam 2, wherein the pneumatic strut 50 will stretch 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, thereby ensuring the smoothness and safety of the entire operation process.

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

[0062] In this embodiment, the upper crossbeam 1 can be preferably made of high-strength stamped iron plate. This material not only has excellent rigidity and stability, but also can effectively play a key role in fixing the locking unit 3, the button unit 4 and the protective seat 8, and 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 crossbeam 1 needs to be strictly considered when selecting materials to ensure that even when 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, and maintaining its long-term reliability and safety.

[0063] The protection seat 8 includes a top seat 80 and a protection cover 81, wherein the top seat 80 is fixed on the upper cross beam 1, and plays the role of shielding the internal structure and installing the protection cover 81; the protection cover 81 is installed on the surface of the top seat 80, and the protection cover 81 is a soft foam material, which is in direct contact with the user's body to prevent the user from contacting hard objects and causing injuries, thereby playing a role in protecting members.

[0064] Furthermore, a decorative cover 6 is provided on one side of the upper cross beam 1 and on both sides of the mounting beam 7. The decorative cover 6 serves to shield the internal structure and ensure the aesthetics.

[0065] In summary, when the protective device is not in use, it is located below the berth and does not affect the normal sitting and resting of the person on the berth. When in use, the protective device is raised to the same height as the person to prevent the person from falling;

[0066] The berth protection device is made of soft foam and leather covering, which can play a cushioning role and provide high protection for personnel;

[0067] Since commercial vehicles have upper and lower berths, and the upper berth is higher from the ground, it is difficult for people to get on the upper berth. Therefore, the berth protection device is designed to provide a stepping device for people to use when they get on the upper berth after it is raised;

[0068] The protective device adopts a hidden locking button design, which has a simple appearance and is easy to operate.
