Description

Technical Field

[0001] The utility model belongs to the field of special vehicle protection, and in particular relates to a grille module hanging structure suitable for protecting a door part of a special vehicle. Background Art

[0002] In recent years, RPG anti-tank rockets, as a handheld portable equipment, can easily destroy combat vehicles with weak armor and low protection. However, special vehicles such as explosion-proof armored personnel carriers, bullet-proof emergency response vehicles, climbing assault vehicles, water cannon vehicles, demolition vehicles, and reconnaissance vehicles used to perform emergency response and stability maintenance tasks usually only have the function of protecting against small-caliber bullets, and some even have no protection capabilities, and cannot achieve effective protection against RPG anti-tank rockets.

[0003] As an additional protective device, the grille module can provide efficient protection against RPG anti-tank rockets. However, due to its own structural characteristics, the conventional fixed support structure used in the door area cannot meet the needs of normal opening and closing of the door, limiting the protective application of the grille module in the door area. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that conventional fixed support structures limit the application of grille modules in vehicle doors, and to propose a grille module mounting structure for special vehicle door protection. Through the ingenious design of the slider guide mechanism, and structural matching and integrated optimization with the grille module, the flexible opening and closing of the vehicle door can be achieved after the grille module is mounted.

[0005] The technical solution of this utility model:

[0006] A grille module hanging structure for protecting the door part of a special vehicle comprises a vehicle body, a vehicle door, a grille support rod, a door hinge, a grille support frame, a grille hinge, a follow-up grille module, a slider guide mechanism, a door grille module and a fixed grille module, wherein the vehicle door is hinged to the vehicle body through the door hinge; the grille support frame and the fixed grille module are rigidly connected to the vehicle body through the grille support rod, and the door grille module is rigidly connected to the vehicle door through the grille support rod; the follow-up grille module is hinged to the grille support frame through the grille hinge; the follow-up grille module and the door grille module are connected through two sets of upper and lower slider guide mechanisms.

[0007] Preferably, the slider guide rail mechanism includes a slider limit block, a guide rail, a guide rail support seat, a slider, a slider connector and a slider fixing member; the guide rail support seat is fixed to the upper and lower frames of the door grille module, and the guide rail is connected and installed on the guide rail support seat; the slider fixing member is installed and fixed to the upper and lower frames of the follow-up grille module; the slider is fixedly connected to the slider connector, the slider is directly mounted on the guide rail, and the slider connector is hinged to the slider fixing member through a pin.

[0008] Preferably, the slider comprises a slider housing and a slider liner, the slider liner is assembled inside the slider housing and is made of wear-resistant self-lubricating materials such as nylon, polytetrafluoroethylene, and super wear-resistant nano plastic.

[0009] Preferably, different door opening and closing angle requirements can be met by changing the length of the guide rail or adjusting the installation position of the slider connector on the frame of the follow-up grille module.

[0010] Beneficial effects of the utility model:

[0011] The grille module mounting structure cleverly designs the follow-up grille module, and innovatively integrates the slider guide mechanism with the door grille module and the follow-up grille module, thereby realizing the flexible opening and closing of the door after the grille module is mounted. The slider guide mechanism adopts a round hole and a round shaft, which has a simple structure and reliable use. The slider lining installed inside the slider is made of wear-resistant self-lubricating material, which can effectively reduce the sliding resistance between the slider and the guide rail, ensuring the smooth operation of the slider guide mechanism. By changing the length of the guide rail or adjusting the installation position of the slider connector on the frame of the follow-up grille module, different door opening and closing angle requirements can be achieved.

[0016] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0017] Figure 1 , Figure 2Shown are schematic diagrams of a grille module hanging structure for protecting the door part of a special vehicle in a closed door state and a schematic diagram of an open door state, respectively. The grille module hanging structure includes a vehicle body 1, a vehicle door 2, a grille support rod 3, a vehicle door hinge 4, a grille support frame 5, a grille hinge 6, a follower grille module 7, a slider guide mechanism 8, a door grille module 9 and a fixed grille module 10, wherein the vehicle door 2 is hinged to the vehicle body 1 through the door hinge 4; the grille support frame 5 and the fixed grille module 10 are rigidly connected to the vehicle body 1 through the grille support rod 3, and the door grille module 9 is rigidly connected to the vehicle door 2 through the grille support rod 3; the left side of the follower grille module 7 is connected to the door grille module 9 through two sets of upper and lower slider guide mechanisms 8, and the right side is hinged to the grille support frame 5 through the grille hinge 6.

[0018] Figure 3 The figure shows a schematic diagram of the structure of the slider and guide rail mechanism, wherein the slider and guide rail mechanism 8 comprises a slider limit block 8-1, a guide rail 8-2, a guide rail support seat 8-3, a slider 8-4, a slider connector 8-5 and a slider fixing member 8-6; the guide rail 8-2 is installed and fixed to the upper and lower frames of the door grille module 9 through the guide rail support seat 8-3; the slider fixing member 8-6 is installed and fixed to the upper and lower frames of the follower grille module 7; the slider 8-4 is fixedly connected to the slider connector 8-5, the slider 8-4 is directly mounted on the guide rail 8-2, and can slide along the guide rail 8-2, and the slider connector 8-5 is hinged to the slider fixing member 8-6 through a pin.

[0019] Figure 4 The figure shows a schematic diagram of the slider structure. The slider 8-4 includes a slider housing 8-4-1 and a slider lining 8-4-2. The slider lining 8-4-2 is assembled inside the slider housing 8-4-1 and is made of wear-resistant self-lubricating materials such as nylon, polytetrafluoroethylene, and super wear-resistant nano-plastics. It can effectively reduce the sliding resistance between the slider 8-4 and the guide rail 8-2, ensuring the smooth operation of the slider guide rail mechanism.

[0020] When the door with the grille module mounted is opened or closed, the door grille module 9 rotates together with the door 2 around the rotating shaft of the door hinge 4. As the door grille module 9 rotates, the slider 8-4 slides along the guide rail 8-2. At the same time, the slider connector 8-5 and the slider fixing member 8-6 rotate relative to each other. The slider fixing member 8-6 drives the follower grille module 7 to rotate around the rotating shaft of the grille hinge 6, thereby realizing the normal opening and closing of the door. The slider limit block 8-1 at the front end of the guide rail 8-2 can prevent the slider 8-4 from falling off during the sliding process; by changing the length of the guide rail 8-2, or adjusting the installation position of the slider connector 8-5 on the frame of the follower grille module 7, different door opening and closing angle requirements can be achieved.
