Technical Field

[0001] This utility model belongs to the field of modular cabin structure technology, specifically relating to a cabin roof opening and closing mechanism. Background Technology

[0002] A modular shelter is a protective, container-like work area constructed by organically combining various sturdy materials. Its volume is fixed or expandable. Similar to shipping containers, modular shelters are standardized with reference to container standards. Depending on the requirements, different equipment and devices are loaded. Compared to shipping containers, modular shelters offer higher reliability, electromagnetic compatibility, airtightness, and thermal insulation.

[0003] The demand for modular cabins is increasing, but traditional modular cabins are either closed or have a semi-open roof. Most modular cabins on the market currently use a door-opening design, which requires a large working area when opening the door. A few modular cabins use a sliding cover design, but the structure is more complex, the cost is higher, and it occupies a large amount of top space, making it inconvenient to use in real-world situations. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a cabin top opening and closing mechanism. This mechanism can easily unfold the cabin top cover to fully expose the equipment on the top of the cabin, which is convenient for the equipment to work. Moreover, the mechanism realizes one-button opening and closing of the cabin top cover, which has high working efficiency and simple structure. It can ensure that the cabin top cover can be opened to a large extent while reducing the space occupied when the cover is opened and closed. It is convenient to use on the top of the cabin with efficient space, thus improving the product competitiveness.

The top of both sides of the hatch is rotatably connected to a rotating rod, and the top of the hatch is connected to the cover on both sides through the rotating rod. Both sides of the upper surface of the hatch are provided with a screw drive mechanism, and a buffer mechanism is provided outside the screw drive mechanism. A drive mechanism that can drive the two screw drive mechanisms is provided between the two ends of the two screw drive mechanisms. Both ends of the two screw drive mechanisms are provided with a linkage mechanism that can control the opening and closing of the cover, and the linkage mechanism at both ends of the screw drive mechanism is connected to the cover on both sides respectively.

[0006] Preferably, the lead screw transmission mechanism includes a fixed seat, a lead screw, and a lead screw slide. The lead screw is laterally rotatably connected inside the fixed seat, and the threads at both ends of the lead screw are opposite to each other. The lead screw slide is connected to both sides of the outside of the lead screw through threaded transmission.

[0007] Preferably, the buffer mechanism includes a first bellows, a second bellows, and a mounting block. The first bellows is fixedly connected to both sides of the lead screw slide. The mounting block is connected to the middle of the lead screw via a bearing and fixedly connected to the middle of the fixed seat. The end of the second bellows away from the first bellows is fixedly connected to the side of the mounting block. Both the first bellows and the second bellows are sleeved on the outside of the lead screw and are both located on the same side with the middle of the lead screw as the dividing line.

[0008] Preferably, the drive mechanism includes a dual-axis geared motor, a first guide shaft, a steering gear, and a second guide shaft. The dual-axis geared motor is fixedly mounted on the upper surface of the cabin, and both ends of its output shaft are connected to the first guide shaft via splines. One end of the first guide shaft away from the dual-axis geared motor is connected to the steering gear, and the second guide shaft is connected to the end of the steering gear away from the first guide shaft.

The second linkages in the two linkage mechanisms on the same side of the two lead screw transmission mechanisms are rotatably connected to both sides of the same lower surface of the cover.

[0010] Preferably, a rotating rod is rotatably connected to the middle of both sides of the two covers, and the two covers and the rotating rods on both sides are symmetrically arranged with the vertical center line of the cabin as the axis of symmetry.

This facilitates the complete unfolding of the hatch roof covers, fully exposing the equipment on top of the hatch, which is convenient for equipment operation. Furthermore, this mechanism enables one-button opening and closing of the hatch roof, resulting in high work efficiency and a simple structure. It ensures a large opening range for the hatch roof covers while reducing the space occupied during opening and closing, making it suitable for use on the top of hatches with limited space, thus enhancing product competitiveness.

[0019] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0020] This embodiment provides a cabin roof opening and closing mechanism, as shown in the attached diagram. Figure 1-5 As shown, it includes a cabin 1 that can be installed on a vehicle body and a cover 2 that covers the cabin 1. The cabin 1 can be installed on the vehicle frame as a component of the modified vehicle and used as a mobile cabin. Various equipment and instruments are installed inside, and it itself is used as a protective device. The top of both sides of the cabin 1 is rotatably connected to a rotating rod 3, and the top of the cabin 1 is connected to the cover 2 through the rotating rod 3. The middle of both sides of the cover 2 is connected to the corresponding rotating rod 3. The two covers 2 and the rotating rods 3 on both sides are symmetrically arranged with the vertical center line of the cabin 1 as the axis of symmetry. Both sides of the upper surface of the cabin 1 are provided with a screw drive mechanism. The screw drive mechanism includes a fixed seat 4, a screw 5 and a screw slide 6. The screw 5 is rotatably connected to the inside of the fixed seat 4, and the threads at both ends of the screw 5 are opposite to each other. The screw slide 6 is connected to both sides of the outside of the screw 5 through thread drive.

[0021] The lead screw drive mechanism is externally equipped with a buffer mechanism, which includes a first bellows 7, a second bellows 8, and a mounting block 9. The first bellows 7 is fixedly connected to both sides of the lead screw slide 6. The mounting block 9 is connected to the middle of the lead screw 5 via bearings and fixedly connected to the middle of the fixed seat 4. The end of the second bellows 8 away from the first bellows 7 is fixedly connected to the side of the mounting block 9. Both the first bellows 7 and the second bellows 8 are sleeved on the outside of the lead screw 5 and are both located on the same side with the middle of the lead screw 5 as the dividing line. On one side, the end of the first bellows 7 near the end of the second bellows 8 can abut against the end of the second bellows 8, while the other side of the first bellows 7 can abut against the inside of the fixed seat 4. The first bellows 7 moves with the movement of the lead screw slide 6. When the first bellows 7 moves laterally with the lead screw slide 6, it will abut against the inside of the fixed seat 4 or the second bellows 8, which can buffer the lateral movement of the lead screw slide 6 and prevent the lead screw slide 6 from directly impacting the fixed seat 4 or the mounting block 9.

[0022] Each end of the two lead screw transmission mechanisms is equipped with a drive mechanism that can drive them. The drive mechanism includes a dual-axis geared motor 10, a first guide shaft 11, a steering gear 12, and a second guide shaft 13. The dual-axis geared motor 10 is fixedly mounted on the upper surface of the cabin 1, and both ends of its output shaft are splined to the first guide shaft 11. One end of the first guide shaft 11 away from the dual-axis geared motor 10 is connected to the steering gear 12. The steering gear 12 can reverse the rotation direction of the second guide shaft 13, enabling the dual-axis geared motor 10 to drive... The first guide shaft 11 and the second guide shaft 13 drive the lead screws 5 on both sides to rotate synchronously in the same direction, so that the lead screw slides 6 on both sides move in the same direction, and the linkage mechanism on both sides can move synchronously, thereby driving the cover 2 to open or close. The second guide shaft 13 is connected to the end of the steering gear 12 away from the first guide shaft 11. The ends of the first guide shaft 11 and the second guide shaft 13 that are far apart from each other are respectively connected to the same end of the lead screws 5 on both sides at right angles. There are two drive mechanisms, and the two drive mechanisms are respectively connected between the two ends of the two lead screws 5.

[0023] Both ends of the two lead screw drive mechanisms are equipped with linkage mechanisms that control the opening and closing of the cover 2. The linkage mechanisms at both ends of the lead screw drive mechanisms are respectively connected to the cover 2 on both sides. The linkage mechanism includes a first linkage 14 and a second linkage 15. The bottom end of the first linkage 14 is rotatably connected to the top of the lead screw slide 6, and the top end is rotatably connected to the middle of the second linkage 15. The end of the second linkage 15 closest to the lead screw slide 6 is rotatably connected to the upper surface of the fixed base 4 on the side close to it, and the end away from the lead screw slide 6 is rotatably connected to the lower surface of the cover 2. The second linkage 15 in the two linkage mechanisms on the same side of the two lead screw drive mechanisms is rotatably connected to both sides of the lower surface of the same cover 2. The bottom of the first link 14 moves with the movement of the lead screw slide 6, while the end of the second link 15 near the lead screw slide 6 is fixed and can only rotate. The top of the first link 14 is rotatably connected to the middle of the second link 15. Therefore, when the lead screw 5 drives the lead screw slide 6 away from the cover 2 that is close to it, the first link 14 will drive the middle of the second link 15 to rotate vertically, thereby causing the part of the second link 15 that is rotatably connected to the cover 2 to move upward, thereby driving the cover 2 to rotate upward towards the cabin 1. The lead screws 5 on both sides can drive the linkage mechanism at both ends to move under the drive mechanism, thereby driving the covers 2 on both sides to retract or unfold synchronously.

[0024] In summary, the operating steps of this cabin top opening and closing mechanism are as follows:

[0025] 1. In the initial state, the covers 2 on both sides abut against each other and cover the top of the cabin 1. When it is necessary to open the covers 2, the dual-shaft reduction motors 10 on both sides are operated to drive the first guide shafts 11 on both sides to rotate synchronously. The rotation direction of the second guide shaft 13 can be reversed through the steering gear 12, so that the lead screws 5 on both sides can rotate in the same direction.

[0026] 2. The rotation of the lead screw 5 can drive the lead screw slides 6 at both ends to move laterally relative to each other through the threaded transmission, so that the lead screw slides 6 on both sides move away from each other, thereby driving the bottom ends of the first connecting rods 14 on both sides to move closer to the edges of the cabin 1, and causing the top ends of the second connecting rods 15 on both sides to tilt in the direction away from each other, thereby driving the covers 2 on both sides to unfold outward.

[0027] 3. The rotating rod 3 and the linkage mechanism can ensure the stability of the structure when the cover 2 is moving, and the second linkage 15 on both sides can rotate to a horizontal state, so that the cover 2 on both sides can be opened to the maximum state. The space required for the cover 2 to be opened is also small, making it easier to operate and use.

[0028] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
