Description

Technical Field

[0001] The invention relates to the technical field of vehicle cabs, and in particular to a special vehicle anti-shock wave cab assembly and a vehicle. Background Art

[0002] Currently, most of the shock wave-resistant cab assemblies are armored vehicle cabs, which are heavy and have poor maneuverability, reducing the vehicle's carrying capacity. Existing off-road vehicle cab assemblies and accessories cannot meet the requirements of impact resistance reliability. There is an urgent need for a cab assembly that can meet the impact resistance requirements, is lightweight, and has a simple manufacturing process.

[0003] At present, the cab assemblies or passenger compartments of shock wave-proof vehicles in the field of special vehicles at home and abroad are mostly basic protective cab assemblies of armored vehicles, that is, the outer skin is in the form of thick plates such as basic bulletproof steel plates, which are heavy and have poor maneuverability, significantly reducing the vehicle's carrying capacity; however, with the complexity and changeability of the combat environment, vehicle maneuverability, lightweight and high load-bearing capacity are important requirements to ensure the combat sustainability and maneuverability of such special vehicles; therefore, it is necessary to design the cab assembly into a lightweight cab assembly that is not welded from thick plates and meets the functional accessories of various vehicle regulations and standards.

[0005] Problem 1: Existing specialized artillery vehicles are mostly armored vehicles with basic protection. The cab accounts for a significant portion of the vehicle's weight, significantly impacting its maneuverability and carrying capacity. Furthermore, ensuring the precision of thick plate welding makes it difficult, resulting in poor cab manufacturing processability and low production efficiency. Conventional vehicle bodies are not strong enough to withstand shock waves.

[0006] Problem two: the opening and closing parts such as doors of existing gun-carrying vehicles and their fixed hinges and locks are heavy; the doors of conventional vehicles cannot meet the strength requirements for shock wave protection, the door locks cannot be locked reliably, the sealing strips are easily fallen off and damaged, and the sealing performance is poor.

[0007] Question three: The cab assemblies of existing gun-carrying vehicles have high material and process manufacturing costs, low production efficiency, a large weight share, and low overall quality.

[0008] Question 4: For special gun-carrying vehicles, the shock wave from the gun barrel exit mainly acts near the rear door of the cab. How to ensure the strength of the rear door of the cab is a problem that needs to be solved. Summary of the Invention

The high-strength and high-rigidity door assembly is formed by welding. The yield strength of the high-strength profile rear door frame is over 500 MPa, and the yield strength of the rear door outer panel is over 700 MPa. The function of the rear door rear end reinforcement baffle is to enhance the strength of the rear end of the rear door to prevent the shock wave from the gun barrel exit from impacting the gap between the rear door and the side panel, thereby avoiding deformation of the rear door due to the shock wave. The rear door outer panel is made of QP980, a high-strength low-alloy steel (HSLA). The thickness of the rear door outer panel is 2mm.The vehicle body assembly includes a cab side panel assembly, which includes a side panel outer panel and a side panel frame. The side panel outer panel and the side panel frame are fixedly connected to the rear door outer panel rear end protruding portion corresponding to the door gap, and a three-level step surface structure is provided at the rear door outer panel reinforcement rib, the rear door rear end reinforcement baffle and the rear door frame position. The first-level step surface formed by the side panel can be in contact with the rear door rear end reinforcement baffle. The rear door rear end reinforcement baffle is made of 5mm high-strength steel plate and is connected to the rear side of the rear door outer panel by welding to prevent the shock wave airflow from directly rushing into the door gap, effectively The direct impact of the shock wave airflow on the door gap and the door sealing strip is weakened. A high-strength reinforcement baffle is welded at the rear of the door to block the door gap and prevent the direct impact of the shock wave airflow on the door gap sealing structure. A primary longitudinal sealing strip with an elliptical cross-section can be tightly clamped between the secondary step surface formed by the side panel outer panel and the side panel frame and the corresponding rear door outer panel reinforcement rib. The primary longitudinal sealing strip is matched and glued to all the longitudinal secondary step surfaces. The primary longitudinal sealing strip is bonded, and the bonding surface is perpendicular to the direction of the door compression sealing strip. The shock wave can only follow the door gap parallel to The bonding surface impacts the primary longitudinal sealing strip to ensure that the sealing strip does not fall off under the action of the shock wave. The end of the third step surface is bent vertically outward to form a connecting support surface, and the connecting support surface is provided with an embedded groove facing the side wall. The secondary longitudinal sealing strip is embedded and fixed outside the embedded groove, and the secondary longitudinal sealing strip can be closely contacted between the connecting support surface and the aligned rear door frame. The secondary longitudinal sealing strip includes a hard long groove with a U-shaped cross section and a flexible sealing long tube with an O-shaped cross section fixedly connected to the upper end of the hard long groove 51 with a U-shaped cross section. The hard long groove 51 with a U-shaped cross section is provided with an embedded groove. Hard barbs protrude from the symmetrical inner walls of the long grooves. The U-shaped, cross-sectional hard long grooves are sleeved onto the outside of the connecting support surface, and the hard barbs are limitedly embedded in the embedded grooves of the connecting support surface. The secondary longitudinal sealing strip, namely the main door sealing strip, is clipped onto the door opening flange formed by the connecting support surface, and the clipping direction is the same as the door compression sealing strip. This structural design prevents the sealing strip from falling off when the door is closed, ensuring that the sealing strip does not fall off under the influence of shock waves, maintaining the door's sealing performance. The two sealing strips ensure that the cab assembly meets the sealing performance requirements under the influence of shock waves.

[0017] The outer surface of the rear door outer panel and the outer surface of the side outer panel in its circumference are coated with a PVC outer paint protective coating. The PVC outer paint protective coating is a polyvinyl chloride coating with a coating thickness of 1.0mm-1.5mm. The polyvinyl chloride coating is sprayed on the rear door area to cushion the damage of the artillery muzzle shock wave to the rear door area of the cab body, delay the damage caused by the impact of the vehicle's outer paint such as ablation and falling off, and comprehensively ensure the overall impact resistance of the cab assembly.

[0018] A special vehicle shock wave proof cab assembly includes a high-strength profile frame and a high-strength thin-plate stamping skin, which are welded to form a high-strength and high-rigidity body assembly. The yield strength of the high-strength profile frame is more than 500 MPa, and the yield strength of the high-strength thin-plate stamping skin is more than 700 MPa. The external welding connection part adopts a full welding design; it also includes a metal lens rearview mirror and a quick-release wiper. The metal lens rearview mirror is installed on both sides of the front windshield of the cab, and the quick-release wiper is installed below the front windshield. The cab assembly uses a metal lens rearview mirror that can be folded forward 180 degrees. The wiper arm is folded to prevent the lens from shattering, ensuring that the rearview mirror meets the standard field of view of the car and can meet the performance requirements of shock wave protection. The cab assembly adopts a quick-release wiper, which is connected to the wiper rod shaft through a mechanical structure. While meeting the requirements of the quick-disassembly wiper arm, the sweeping area is guaranteed to meet the driving field of view area requirements of the vehicle driver and ensure the driver's daily driving safety field of view. At the same time, the wiper arm can be quickly separated and quickly installed in the anti-shock wave working condition, ensuring the wiper function and avoiding damage such as collision and scratching of the wiper arm with the windshield and the surrounding area of the wiper.
