The principles of applying the cab and airdrop vehicle to other types of equipment are essentially the same as those applied to airdrop vehicles, and will not be repeated here.

[0021] First, see Figures 1 to 4 An embodiment of the present invention provides a cab, comprising: a cab structure and a beam system structure, the cab structure comprising a top cover assembly 1, a front windshield assembly 2, a front enclosure assembly 3, a side enclosure assembly 4 and a rear enclosure assembly 5, the top cover assembly 1, the front windshield assembly 2, the front enclosure assembly 3 and the rear enclosure assembly 5 are sequentially connected and enclosed to form a vertical sealing structure, the side enclosure assembly 4 comprises a left enclosure assembly 41 and a right enclosure assembly 42 arranged on both sides of the vertical sealing structure; the beam system structure comprises a plurality of reinforcing beams, the middle portion of each of the reinforcing beams is recessed toward the interior of the cab structure to form a groove-shaped stabilizing portion, and both sides thereof form overlapping portions for connecting the cab structure; wherein, with the central axis of the front enclosure assembly 3 as a reference, the top cover assembly 1, the front windshield assembly 2, the side enclosure assembly 4 and the rear enclosure assembly 5 are symmetrically arranged.

[0022] In this scheme, a vertical sealing structure is formed by connecting and enclosing the top cover assembly 1, the front windshield assembly 2, the front enclosure assembly 3 and the rear enclosure assembly 5 in sequence, and the left enclosure assembly 41 and the right enclosure assembly 42 are respectively arranged on both sides of the vertical sealing structure to form a cab structure, wherein the top cover assembly 1, the front windshield assembly 2, the side enclosure assembly 4 and the rear enclosure assembly 5 are symmetrically arranged with the central axis of the front enclosure assembly 3 as a reference, so that the outer shape of the cab is basically symmetrical, which is convenient for confirming the load distribution position and easy to adjust the landing posture during airdrop; in the cab structure, reinforcement and stabilization are carried out by setting a beam system structure, wherein the middle part of each of the reinforcing beams is recessed into the interior of the cab structure to form a groove-shaped stabilizing part, and overlapping parts are formed on both sides, so that the reinforcing beam is connected to the cab structure through the overlapping parts on both sides, and the reinforcing beam adopts a channel steel structure, and grooves are opened on the overlapping edges to improve the strength of the cab structure, so as to achieve the purpose of improving the safety performance of the whole vehicle.

[0023] It is understandable that in order to more quickly confirm the load distribution position and not affect the accuracy of adjusting the landing posture, in some possible embodiments, the beam system structure is also distributed in the cab structure in a symmetrical manner, and the several reinforcement beams it contains are symmetrically arranged with the central axis of the front enclosure assembly 3 as the reference. The cab outer shape is a symmetrical structure, and the overall structure is simple. At the same time, in the pre-airdrop working condition, it is convenient to fix the mooring; in the airdrop working condition, it is convenient to evenly distribute the load position, and it is easy to adjust the landing posture during the airdrop to ensure landing in a positive posture.

[0024] The cab structure uses a beam structure to improve strength and achieve stable connection between various assemblies. In order to distinguish the reinforcement beams, in this embodiment, please refer to Figures 1 to 3 , several reinforcement beams are defined as front windshield upper beam 8, front windshield lower beam 9, A-pillar support beam 10, door frame upper beam 11, B-pillar support beam 12, cavity beam 7, roof support beam 14 and rear surround beam 15.

According to the calculation conditions, the cross-sectional area of ​​the front windscreen lower crossbeam 9 is designed according to the airdrop calculation strength, which can ensure the full strength under the airdrop condition. The thickness of the front windscreen lower crossbeam 9 is selected to be 2.0-3.0mm, and the material is high-toughness steel.

[0026] The internal framework of the side enclosure assembly 4 is shared with the connecting parts of the top cover assembly 1, the front windshield assembly 2, and the front enclosure assembly 3. Its structure is mainly as follows: the connection is composed of continuous stamping parts, and starting from the A-pillar of the cab, the A-pillar support beam 10, the door frame upper cross beam 11, and the B-pillar support beam 12 are arranged in sequence. The A-pillar support beam 10 is arranged at the position of the left side enclosure assembly 41 and the right side enclosure assembly 42 close to the front windshield assembly 2. It is an integrally bent closed cavity beam and is arranged in sequence along the edge of the side of the side enclosure assembly 4. One side is fixedly welded to the inner side of the outer plate of the left side enclosure assembly 41 or the right side enclosure assembly 42, and the other side is welded to the inner side of the outer side of the front windshield assembly 2. At the same time, it is also welded to the inner side of the front enclosure outer plate 31 of the front enclosure assembly 3. Since the A-pillar support beam 10 adopts a bent closed cavity, it has the advantages of simple production process, high manufacturing precision, and low cost.

[0027] The connecting part between the A-pillar support beam 10 and the cab door frame is the door frame upper cross beam 11, wherein the door frames of the left side panel assembly 41 and the right side panel assembly 42 are both provided with the door frame upper cross beam 11, which is a stamped part welded to the inner side of the outer plate of the side panel assembly 4 to form a support structure, and a groove recessed toward the inside of the cab structure is provided at the overlapped edge thereof.

[0028] The B-pillar support beam 12 is arranged at a position of the left side panel assembly 41 and the right side panel assembly 42 close to the rear panel assembly 5. The B-pillar support beam 12 is bent and formed into a channel steel structure, and is welded to the inner side of the outer panel of the side panel assembly 4 and the inner side of the outer panel of the rear panel assembly 5 to form a closed cavity.

[0029] Among them, the two sides of the door frame upper cross beam 11 are respectively welded to the A-pillar support beam 10 and the B-pillar support beam 12. The door frame upper cross beam 11 and the B-pillar support beam 12 are welded by MAG welding, and a triangular support joint 13 is provided at the overlap between the two, so that the door frame upper cross beam 11 and the B-pillar support beam 12 are welded through the triangular support joint 13, which is used to strengthen the connection strength between the door frame upper cross beam 11 and the B-pillar support beam 12, and ensure the integrity of the door frame structure after airdrop landing.

[0030] Preferably, in some embodiments, see Figure 2 , a plurality of top cover support beams 14 are also provided, and the plurality of top cover support beams 14 are arranged on the inner side of the outer plate of the top cover assembly 1 in a crisscross manner, forming a frame structure welded on the inner side of the outer plate of the top cover assembly 1, wherein several top cover support beams 14 arranged parallel to the rear enclosure assembly 5 have one end extending to the inner side of the rear enclosure assembly 5, and the end face thereof is set as an inclined surface, thereby forming a triangular support portion, which is welded to the inner side of the outer plate of the rear enclosure assembly 5 through the triangular support portion to form a fixed connection, so that the top cover assembly 1 and the rear enclosure assembly 5 form a whole, and increase the torsional rigidity of the top cover support beam 14 to the top cover assembly 1 and the rear enclosure assembly 5. It should be noted that the arrangement of the rear enclosure and the top cover beam system shown in the figure is a partially simplified schematic diagram, which does not represent the specific physical state.

[0031] Further, in some embodiments, see Figure 1 A plurality of longitudinal reinforcing ribs 17 are also arranged symmetrically on the top surface of the outer plate of the top cover assembly 1 to improve the overall rigidity of the top cover panel.

[0032] Preferably, in some embodiments, see Figure 2 , a plurality of rear enclosure beams 15 are arranged on the inner side of the rear enclosure assembly 5, and the plurality of rear enclosure beams 15 are arranged in sequence along the height direction and the width direction of the rear enclosure assembly 5, some of the rear enclosure beams 15 are arranged to extend along the width direction of the rear enclosure assembly 5, and the other part of the rear enclosure beams 15 are arranged to extend along the height direction of the rear enclosure assembly 5, forming a frame structure. It should be noted that the illustrated rear enclosure beam arrangement is a local simplified schematic diagram and does not represent the specific physical state. Of course, in other possible embodiments, the rear enclosure beam 15 is not limited to this, and the rear enclosure assembly 5 is an outer plate composite beam system structure. After topological analysis, the arrangement area and quantity of the rear enclosure beam 15 are determined to ensure a reasonable connection beam system arrangement and to ensure the overall airdrop performance.

[0033] Further, in some embodiments, see Figure 1 Two groups of hanging ears 43 are fixedly welded on the outer sides of the outer panels of the left side panel assembly 41 and the right side panel assembly 42. The two groups of hanging ears 43 are symmetrically arranged with respect to the central axis of the front panel assembly 3 as a reference. The hanging ears 43 are used for cab installation and transportation.

[0034] Preferably, in this embodiment, please refer to Figure 1The front enclosure assembly 3 includes a front enclosure outer panel 31, a front enclosure floor 32 and a middle channel 33. The middle channel 33 runs through the front enclosure assembly 3 and the rear enclosure assembly 5. A plurality of floor beams are arranged on the front enclosure floor 32. The middle channel 33 is connected to the vertical support beam of the front enclosure floor 32 through a floor adapter 16. The floor adapter 16 is symmetrical along the X-direction and Y-direction central axis of the middle channel 33. The floor adapter 16 is partially avoided along the middle channel 33 on the basis of ensuring the installation surface requirements of the suspension assembly 6, thereby saving the space for arranging the floor adapter 16 on the floor surface. The floor beams on the floor panel of the front enclosure floor 32 are arranged in a frame type and are welded to the floor panel of the front enclosure floor 32 by MAG welding.

[0035] In some preferred implementation examples, the floor beam adopts a channel steel structure, and a groove recessed toward the interior of the cab structure is formed at the overlapped edge of the floor beam with the floor panel.

[0037] In order to improve the bearing capacity of the top cover, in this embodiment, please refer to Figure 1 and Figure 2 The top ends of the left side panel assembly 41 and the right side panel assembly 42 are connected to the top cover assembly 1 after being bent, and the bent portions of the left side panel assembly 41 and the right side panel assembly 42 form a trapezoidal interval that gradually expands from top to bottom. The bent portions of the left side panel assembly 41 and the right side panel assembly 42 are connected to the triangular supporting portion of the top cover support beam 14, so that the connection between the side panel assembly 4 and the top cover assembly 1 is supported by an inclined surface, thereby enhancing the connection strength between the overall top cover assembly 1 and the side panel assembly 4 and improving the bearing capacity of the top cover.

[0038] Further, in some possible embodiments, see Figure 1 The front windshield assembly 2 is a frame structure, and the overall structure is an outer plate composite beam system. It should be noted that the load-bearing beam system of the front windshield assembly 2 uses a similar channel steel structure to improve the overall support strength of the front windshield. The load-bearing beam system of the front windshield assembly 2 adopts a topological arrangement based on the calculation conditions, and uses the topological optimization method to determine the optimal spatial distribution of beams and other structural elements in the design domain to achieve specific optimization goals, such as maximum stiffness or satisfying stress conditions. This process involves seeking the optimal configuration of the position and number of non-solid areas inside the structure, as well as the optimization of the layout of components in the structure and the node connection method, while satisfying constraints such as stress and displacement, so that the structure can effectively transfer external loads to the structural support position, while optimizing certain performance indicators of the structure to ensure the strength of the area with the maximum impact in the airdrop condition.

[0039] Preferably, in this embodiment, the outer panels of the cab are made of 2-3mm high-strength steel plates, that is, the outer panels of the top cover assembly, front windshield assembly, front panel assembly, side panel assembly and rear panel assembly are all 2-3mm thick, which can carry greater loads and pressures, and can simplify the weight of the outer panels, effectively reducing the weight of the structure itself.

[0040] In some possible embodiments, see Figure 2 The cab also includes a suspension assembly 6, which is arranged at the bottom of the front assembly 3 and is welded to the floor of the front assembly 3 by MAG. The cab structure can be connected to the chassis of the cab through the suspension assembly 6.

[0042] The present invention provides a cab structure and a beam system structure, studies the performance requirements of each stage of airdrop, simplifies the structure and performs special structural mechanics design processing on the special force-bearing structure, and thus has a streamlined structure that is easy to manufacture and maintain. In addition, the cab outer shape is basically symmetrical, which is convenient for confirming the load distribution position and adjusting the landing posture during airdrop, so that the cab has the advantages of being easy to be tied before airdrop and easy to adjust the landing posture during airdrop. At the same time, the load-bearing or supporting beam system structure adopts a channel steel structure, which is easy to manufacture and low in cost by opening grooves on the overlapping edges. The cab assembly is a manufacturing unit, which is easy to replace and maintain.

[0043] The outer panels of the cab structure of the present invention are all made of 2-3 mm high-strength steel plates, which can bear greater loads and pressures and meet the force strength requirements of the entire airdrop working process.
