Description

Technical Field

[0001] This invention relates to the field of bulletproof vehicle door technology, and in particular to a bulletproof vehicle door assembly and a bulletproof vehicle. Background Technology

[0002] Currently, most traditional bulletproof vehicles achieve their protection by adding steel plates or other composite armor to the inside of the vehicle body. Not only must the vehicle body be bulletproof, but the windows must also be replaced with bulletproof glass. Traditional vehicle doors have limited interior space, and this temporary modification method of adding steel plates or other composite armor cannot provide comprehensive protection for the doors, easily creating blind spots. Bulletproof glass is relatively thick and heavy, significantly impacting the reliability of the window regulator. After adding bulletproof glass, the window operation is also very slow and inconvenient. Bulletproof doors produced using this modification method have very low production efficiency, cannot meet the needs of mass production, and their interior space layout is cluttered, resulting in large doors that occupy a lot of interior space.

[0003] Due to the unique nature of military combat off-road vehicles, these vehicles must possess a certain level of ballistic protection, strong battlefield survivability, and counter-attack capabilities, adapting to various complex and harsh road conditions. This necessitates that the vehicle door assemblies differ from those of ordinary vehicles. These doors must not only meet comprehensive ballistic protection requirements but also provide easily openable and closeable firing windows, allowing soldiers to conveniently and quickly open and close them for combat firing. Simultaneously, better ballistic protection results in a heavier overall vehicle weight. For military combat vehicles, high mobility is also crucial while ensuring protective performance. Therefore, the door assemblies must minimize their own weight to ensure lightweight design while meeting protective requirements.

[0004] For example, patent number CN202010406463.3 provides a bulletproof door and vehicle, which includes an inner panel and a bulletproof plate. The bulletproof plate is located outside the inner panel and is welded to the inner panel; the weld formed by the bulletproof plate and the inner panel is located on the side opposite to the inner panel. By placing the bulletproof plate on the outside, the problem of large space occupation when the bulletproof plate is placed on the inside is effectively solved, leaving more space for the arrangement of other accessories inside the door. Moreover, placing the weld inside eliminates the weld on the bulletproof door's frontal surface, improving the stability of the bulletproof door's ballistic performance. However, it does not demonstrate the comprehensive bulletproof capability of the entire door assembly, lacks combat counterattack capability, and is difficult to adapt to various complex and harsh road conditions. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and to propose a bulletproof door assembly and a bulletproof vehicle, thereby solving the technical problems of incomplete bulletproof capability and lack of combat counterattack capability in the existing bulletproof door assembly.

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0059] This invention provides a bulletproof door assembly and a bulletproof vehicle.

[0060] Example 1: This invention provides a bulletproof vehicle door assembly, such as... Figures 1 to 4 As shown, it includes the outer door panel 1, the inner door panel 2, the bulletproof sliding window 3, and two locking components 4.

[0061] like Figures 8 to 9 As shown, the middle part of the outer door panel 1 is bent outward to form an upper anti-bullet surface 11 and a lower anti-bullet surface 12. The upper anti-bullet surface 11 is provided with a sliding window mounting opening 13. The inner door panel 2 is welded to the outer door panel 1. The door has high rigidity and strength, simple and reliable structure, and is easy to assemble and maintain. It achieves lightweighting while ensuring bulletproof performance.

[0062] Specifically, the angle of the bending angle formed by the upper anti-ballistic surface 11 and the lower anti-ballistic surface 12 is 157°, and the lower plane of the outer door panel 1 is at an angle of 82° to the horizontal plane.

[0063] In this device, the outer door panel 1 is bent in the middle. After bending, the upper anti-bullet surface 11 and the lower anti-bullet surface 12 together form the anti-bullet outer surface of the door assembly. The bending angle formed by the two planes faces outward. The special angle formed by the anti-bullet outer surface of the door assembly can effectively deflect the direction of bullet movement and improve the bulletproof performance of the outer door panel 1.

[0064] like Figure 4 , Figure 5 As shown, the bulletproof sliding window 3 includes a fixed guide rail 31 and a sliding window glass 32. The fixed guide rail 31 is bolted to the sliding window mounting opening 13 of the outer panel of the door 1. It has a groove inside that allows the sliding window glass 32 to be smoothly pushed and pulled horizontally. The sliding window glass 32 is slidably disposed in the groove. The sliding stroke of the sliding window glass 32 has an observation position that slides to block the sliding window mounting opening 13 to allow the user to observe the outside world safely, and an operational position that slides along the groove to reserve a firing port at the sliding window mounting opening 13.

[0065] Two locking components 4 are connected to the sliding window glass 32 located at the observation station and the sliding window glass 32 located at the combat station, respectively, to lock the sliding window glass 32 located at the observation station and the combat station.

[0066] In this device, the bulletproof sliding window 3 is integrated with the outer door panel 1 to meet the comprehensive protection requirements of the door assembly. The sliding window glass 32 can slide along the groove on the fixed guide rail 31 and has two sliding positions. When sliding to the observation position, the sliding window glass 32 blocks the sliding window mounting opening 13. At this time, the sliding window glass 32 is used to protect the sliding window mounting opening 13 so that the user can safely observe from inside the door assembly. When sliding to the combat position, an opening with a certain distance is formed between the sliding window glass 32 and the sliding window mounting opening 13. This opening is a safety firing port reserved for combat, so that the door assembly has a firing window that can be opened and closed at any time to meet the needs of soldiers' door assault operations. When the sliding window glass 32 is in the observation position or the combat position, the corresponding locking member 4 can fix the sliding window glass 32 respectively, which can realize the locking and unlocking functions of the bulletproof sliding window 3.

[0067] like Figure 1 ,and Figure 2 As shown, the outer door panel 1 is a 4.6mm thick bulletproof steel plate arranged on the outermost side. The outer door panel 1 and the bulletproof sliding window 3 can effectively resist the firing of Type 53 7.62mm ordinary steel core bullets at 100m. The two can achieve all-round protection of the door and provide a guarantee for the bulletproof performance of the door.

[0068] Furthermore, two sliding window lock mounting brackets 34 are welded to the outer door panel 1 at the corresponding positions of the two locking components 4 using MAG welding to fix the mounting bracket 41. The outer door panel 1 is provided with mounting holes for the bulletproof sliding window 3, the door hinge assembly, and the door lock assembly, respectively, at the corresponding positions of the bulletproof sliding window 3, the door hinge 5, and the door lock assembly 6. This allows the bulletproof sliding window 3, the door hinge 5, and the door lock assembly 6 to be directly installed on the outer door panel 1 with screws. The outer door panel 1 serves as a structural component while providing mounting holes for the door hinge 5 and the door lock assembly 6. Nuts are welded to the back of each mounting hole for easy installation.

[0069] Furthermore, the outer door panel 1 has a curved flange along its circumference that extends towards the inner door panel 2, which can further enhance the overall rigidity of the door.

[0070] like Figure 1 As shown, in some embodiments, the inner door panel 2 is made of 1mm thick ordinary stamped steel plate. The inner door panel 2 and the outer door panel 1 are welded together to increase the overall strength of the door. The inner door panel 2 is partially welded with a door lock reinforcing plate 67 connected to the door lock assembly 6. The inner door panel 2 is provided with sealing strip 10 mounting holes around its perimeter so that the inner door panel 2 can increase the overall strength and rigidity of the door. At the same time, it provides mounting points for the door guard plate, sealing strip 10, etc.

[0071] The door assembly uses the outer door panel 1 as a structural component, selects an inner door panel 2 of appropriate thickness formed by one-piece stamping, and adopts the method of adding local reinforcing welded parts at the connection, so that it can achieve lightweight while meeting the requirements of strength, rigidity and bulletproof performance.

[0072] To facilitate sliding and pulling of the sliding window glass 32, such as Figure 4 , Figure 5 As shown, in some embodiments, a sliding window handle 35 is provided on the inner side of the sliding window glass 32.

[0073] To facilitate use in actual combat, such as Figure 4 , Figure 5 As shown, in some embodiments, the sliding stroke of the sliding window glass 32 is horizontal. Of course, although this embodiment describes the sliding stroke of the sliding window glass 32 as horizontal, the sliding window glass 32 can also be configured to slide in a lifting manner, etc., as needed.

[0074] like Figure 6 , Figure 7 As shown, in some embodiments, each locking component 4 includes a mounting bracket 41, a fixing sleeve 42, a pull rod 43, a lifting knob 44, and a locking block 45. The mounting bracket 41 is fixedly mounted on one side of the fixing guide rail 31. The fixing sleeve 42 is fixedly connected to the mounting bracket 41. The pull rod 43 is slidably connected to the fixing sleeve 42. One end of the pull rod 43 protrudes to the outside of the fixing sleeve 42 and is fixedly connected to the lifting knob 44. The other end of the pull rod 43 is fixedly connected to the locking block 45. The locking block 45 is slidably mounted on the mounting bracket 41 through an elastic reset member. A sliding window latch 33 is provided on one side of the bulletproof sliding window 3 at a position corresponding to the locking block 45 for engaging with the locking block 45 to fix the sliding window glass 32.

[0075] In use, the locking block 45 can abut against the sliding window latch 33 inside the mounting bracket 41 to limit and fix the sliding window glass 32. When it is necessary to unlock the sliding window glass 32, the lifting knob 44 is pulled outward, which can drive the locking block 45 outward through the pull rod 43 so that the locking block 45 is disengaged from the sliding window latch 33. At this time, the sliding window glass 32 can continue to slide on the fixed guide rail 31 to adapt to different combat needs.

[0076] Furthermore, the elastic reset component may include a spring, an elastic sheet, etc., which are fixedly connected to the locking block 45 and the mounting bracket 41 respectively, so as to connect with the locking block 45 and the mounting bracket 41, so that the locking block 45 can be kept in the extended state inside the mounting bracket 41 under the elastic force of the elastic reset component. After the fixing sleeve 42 is loosened, the locking block 45 can be reset under the elastic action of the elastic reset component, so as to facilitate locking and unlocking of the sliding window glass 32.

[0077] like Figure 7 As shown, in some embodiments, the end of the locking block 45 near the side of the sliding window glass 32 forms an inclined angle. During the process of pushing the sliding window glass 32 to the designated position, the sliding window latch 33 abuts against the sliding window latch 33, so that a driving force is generated at the inclined angle to drive the locking block 45 to slide and retract, so that the sliding window latch 33 slides to engage with the other side of the locking block 45, so as to automatically lock the sliding window glass 32 when it moves to the designated position.

[0078] like Figure 1 , Figures 10 to 13 As shown, in some embodiments, the bulletproof door assembly also includes a door hinge 5, a door lock assembly 6, a door interior panel 7, and a sealing strip 10.

[0079] Furthermore, such as Figure 2 As shown, the door hinge 5 is connected to the body of a bulletproof vehicle and the outer door panel 1 respectively, for the purpose of installing the outer door panel 1 to the bulletproof vehicle, so as to support the outer door panel 1 and realize the opening and closing of the outer door panel 1.

[0080] Furthermore, there are at least two door hinges 5, and each door hinge 5 is bolted to the outer side of the door panel 1 and the body. The door hinges 5 are designed as external open hinges and are connected by bolts, which facilitates quick repair and replacement after combat damage. All door hinges 5 are made of titanium alloy material, which has high strength and excellent lightweight performance.

[0081] Furthermore, such as Figure 10 As shown, the door lock assembly 6 is located on the outer panel 1 of the door and is used to lock and unlock the door assembly and the bulletproof vehicle.

[0082] Furthermore, the door lock assembly 6 includes: a lock body 61, a bolt 62, an outward-opening door handle 63, an inward-opening door handle 64, a lock cylinder 65, and a lock stop knob 66. The lock body 61 is bolted to the outer door panel 1. The bolt 62 is located inside the lock body 61. The outward-opening door handle 63 and the inward-opening door handle 64 are rotatably connected to both sides of the lock body 61, and both are connected to the bolt 62. In use, rotating the outward-opening door handle 63 or the inward-opening door handle 64 moves the internal structure of the lock body 61, thereby driving the bolt 62 to retract into the lock body 61 or extend to protrude beyond the lock body 61. After the lock body 61 is installed, the bolt... 62 corresponds to the keyhole provided on the bulletproof vehicle. After protruding from the outside of the lock body 61, it extends into the corresponding keyhole. The door outward opening handle 63 and the door inward opening handle 64 are directly connected to the lock body 61, eliminating the need for the pull rod 43 or pull cable transmission. This omits the transmission mechanism, resulting in higher transmission efficiency, simple and efficient assembly, and stable and reliable operation. The door lock cylinder 65 is located on the lock body 61 and connected to the lock tongue 62. The door lock anti-rotation knob 66 ​​is connected to the door lock cylinder 65. Rotating the door lock anti-rotation knob 66 ​​can lock the door independently, preventing the door from being opened accidentally during travel.

[0083] Furthermore, such as Figure 5 , Figure 11 , Figure 12 As shown, the interior door panel 7 is installed on the inside of the door inner panel 2 by a number of self-tapping screws 71. The screws are securely and reliably fastened, and also facilitate repeated disassembly and maintenance. Each self-tapping screw 71 includes a clip body 711, a pre-tightening screw 712, and a clip cap 713. The clip body 711 is located between the mounting surface and the pre-tightening screw 712 and corresponds to the pre-set mounting hole on the door inner panel 2. The pre-tightening screw 712 passes through the clip body 711 and is threadedly connected to the interior door panel 7 and the door inner panel 2. The clip body 711 has a groove in the middle for accommodating the head of the pre-tightening screw 712. The clip cap 713 is engaged in the groove by a circumferential groove and is used to cover the head of the pre-tightening screw 712 after it is installed. In practical use, directly using ordinary self-tapping screws to fasten the interior door panel 7 results in the screw head being exposed on the mounting surface, posing a risk of scratching people and being unsightly. Therefore, a snap-on self-tapping screw component 71 was designed to solve the above problems. The self-tapping screw component 71 consists of three parts: a snap cap 713, a snap body 711, and a self-tapping screw. By engaging the snap cap 713 with the snap body 711, the head of the self-tapping screw can be completely covered. Both parts have smooth outer surfaces that will not cause injury and have an aesthetically pleasing appearance.

[0084] Furthermore, such as Figure 5As shown, the inner side of the door interior panel 7 is also equipped with parts such as an interior armrest 8 and a net pocket 9. An armrest mounting bracket 81 is welded onto the outer door panel 1. The interior armrest 8 is bolted to the armrest mounting bracket 81. The interior armrest 8 is for use by the user inside the vehicle, making opening and closing the door more convenient. The net pocket 9 is made of polypropylene and a steel frame, which can increase the storage space of the door assembly and facilitate the retrieval of stored items. Both the interior armrest 8 and the net pocket 9 in this device are fastened with bolts. Whether or not to install them can be decided based on actual configuration requirements. If the interior armrest 8 and the net pocket 9 are removed, installation space can be reserved for other equipment, such as mounting a gun clip to hold a rifle or storing a first-aid kit.

[0085] Furthermore, such as Figure 13 As shown, the sealing strip 10 is installed on the inner panel 2 of the door with a snap fastener. The surface of its bubble tube is coated with a slip-enhancing coating, which can make the surface friction coefficient of the sealing strip 10 bubble tube less than 0.5, effectively delaying the wear of the sealing strip 10 and increasing the life of the sealing strip 10.

[0086] Furthermore, the sealing strip 10 has an internal hollow structure. When the door assembly and the vehicle are closed, it has a certain degree of plasticity to ensure that the door assembly and the vehicle are closed stably, while preventing damage to the door assembly and the vehicle.

[0087] Example 2: The present invention also provides a bulletproof vehicle, which includes the above-mentioned bulletproof door assembly. The bulletproof vehicle is an off-road vehicle, and may also include other fuel-powered bulletproof vehicles or electrically powered bulletproof vehicles.

[0088] In some embodiments, the bulletproof vehicle is provided with a door mounting opening that fits the bulletproof door. After the door is closed, the body of the bulletproof vehicle and the bulletproof door assembly press the sealing strip 10 together to seal the two. The outer side of the body of the bulletproof vehicle is provided with threaded mounting holes corresponding to the door hinge 5 for the connection between the door and the body and the outer door panel 1, which is convenient for disassembly, assembly and maintenance.

[0089] The present invention bends the outer panel 1 of the car door to form an upper anti-bullet surface 11 and a lower anti-bullet surface 12. The special angle formed by the anti-bullet surface can effectively deflect the direction of bullet movement and improve the bulletproof performance of the outer panel 1 of the car door.

[0090] The present invention arranges the bulletproof sliding window 3 on the upper bullet-facing surface 11, so that the bulletproof sliding window 3 has the ability to deflect the direction of bullet movement, so that the outer panel of the car door 1 and the bulletproof sliding window 3 can meet the comprehensive protection requirements of the car door assembly.

[0091] The present invention features a bulletproof sliding window 3, which can be opened and closed by sliding, allowing soldiers to observe or fire at the outside world while being protected, thereby enhancing their combat counterattack capabilities.

[0092] The present invention uses a locking component 4 to lock the sliding window glass 32 located at the observation and combat positions, which can realize the locking and unlocking functions of the bulletproof sliding window 3. The sliding window glass 32 can be opened and closed quickly and conveniently from inside the vehicle, which can meet the needs of soldiers to observe the situation outside the window and fire from inside the vehicle.

[0093] The outer door panel 1 of the present invention serves as a bulletproof function and also provides an installation interface for other parts as a structural component. The door has high rigidity and strength, simple and reliable structure, and is easy to assemble and maintain. It achieves lightweighting while ensuring bulletproof performance.

[0094] In this invention, all components of the door assembly are installed using bolts, screws, and clips. The door assembly is simple to assemble, and each component can be quickly disassembled and replaced after being damaged in combat. It is easy to repair and has strong battlefield practicality.

[0095] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
