Description

Technical Field

[0001] This invention belongs to the technical field of protective accessories for special vehicles, specifically relating to an outward-protruding bulletproof shooting window for special vehicles. It is mainly used for installation on the side wall of the passenger compartment of special commercial vehicles, armed escort vehicles, and military and police riot control vehicles, realizing multiple functions such as deterrence, shooting through the window, internal and external communication, ventilation and observation, and bulletproof and riot control. Background Technology

[0002] In the field of escort and special military / police vehicles, bulletproof firing windows are a key component of vehicle security. With the window open, occupants can fire weapons from inside the vehicle to deter criminals and communicate with those outside to exchange small items. When the window is closed, the bulletproof structure protects against bullets and impacts from hard objects, ensuring the safety of occupants. Currently, most bulletproof firing windows on the market use a modular, disassembled assembly structure, which has revealed several inherent defects in long-term practical use. First, the protection is unreliable. Existing bulletproof covers rely solely on simple clips for fixation, making them prone to detachment upon impact with bullets or heavy objects. This renders the overall bulletproof protection of the window ineffective, allowing intruders to enter the cabin and posing a significant safety hazard. Second, the sealing performance is poor. Conventional products only have a single layer of sealing strips, resulting in a simple sealing structure between the window frame and the cover, and between the window frame and the vehicle body. When the vehicle is in rainy weather or driving on dusty roads, rainwater and dust can easily seep into the cab through assembly gaps, corroding the wiring and interior materials, creating a safety hazard. Third, the assembly and... The drawbacks are obvious. The traditional shooting window base is in direct, rigid contact with the bulletproof glass. The impact and vibration from gunfire and the stress from vehicle travel are directly transmitted to the bulletproof glass, which can easily cause the glass to crack and break. At the same time, the old-fashioned locking structure has a cumbersome opening and closing procedure, and the window cannot be opened quickly in case of a sudden emergency, which delays the response time. Finally, the product has low integration, serious non-standardization of parts, complicated installation procedures, rough appearance of the whole vehicle after modification, and different models need to be customized with separate molds. It has poor versatility and cannot meet the needs of lightweight and compact modification of multiple models of escort, military and police vehicles.

[0003] In summary, existing bulletproof shooting windows suffer from several industry pain points, including easy detachment of the cover plate due to impact, poor sealing performance, easy damage to bulletproof glass due to vibration, cumbersome opening and closing operations, and a narrow range of vehicle compatibility. These issues hinder product upgrades and use. Therefore, there is an urgent need to develop an outward-pushing bulletproof shooting window with multi-layer sealing, cover plate limiting to prevent detachment, flexible buffering and shock absorption, and integrated assembly. Summary of the Invention

[0004] The objective of this invention is to provide a compact, easy-to-operate, reliably sealed, and high-performance ballistic protection push-out bulletproof window for special vehicles. This design helps achieve stable and reliable bulletproof cover plates through structural optimization, ensuring they do not fall off under impact. It also facilitates buffering and isolation between the window frame and the bulletproof base material using a flexible assembly structure, preventing damage to the bulletproof glass from vibration and impact. Furthermore, it allows for rapid opening and closing of the bulletproof cover plates using a bidirectional rotating handle with self-locking limit. Simultaneously, it simplifies the overall assembly and disassembly process, broadens the range of vehicle models it can be adapted to, reduces maintenance costs throughout the equipment's lifecycle, and meets the long-term safe operation requirements of various escort, military, and police special vehicles under complex and harsh working conditions.

[0005] The objective of this invention is achieved as follows: an outward-protruding bulletproof firing window for special vehicles, comprising: a window frame assembly including an outer ring and an inner ring of the firing window, the outer ring and the inner ring being respectively located on the outer and inner sides of the firing window of the special vehicle and arranged coaxially; a bulletproof cover assembly housed on the outer ring of the firing window; a handle assembly passing through the window frame assembly from the inside of the special vehicle's cabin, and being fixedly connected to the bulletproof cover assembly and capable of rotating the bulletproof cover assembly; an elastic clamping member abutting between the outer ring of the firing window and the handle assembly, and continuously applying a clamping preload to the handle assembly and the bulletproof cover assembly under normal conditions, so that the bulletproof cover assembly and the outer ring of the firing window remain closed; by rotating the handle assembly at a limited angle, the bulletproof cover assembly is pushed outward to open or retracted inward to close, thereby realizing the opening and closing of the firing window of the special vehicle.

[0006] In a specific embodiment of the present invention, the handle assembly includes a handle grip and a handle connecting sleeve connected to the handle grip. The handle grip is located inside the special vehicle cabin, corresponding to the inner side of the inner ring of the firing window. The handle connecting sleeve is cylindrical and hollow inside, forming a handle connecting sleeve cavity. A handle connecting sleeve positioning groove is formed on the inner ring of the firing window, corresponding to the position of the handle connecting sleeve. The handle connecting sleeve can be inserted into the handle connecting sleeve positioning groove and reciprocate and slide within it. The bulletproof cover plate assembly includes a cover plate body and a cover plate connecting post connected to the cover plate body. The cover plate connecting post is adapted to and placed within the inner ring of the handle connecting sleeve. After the cover plate connecting post and the handle connecting sleeve are inserted and positioned, they are radially locked and fixed by connecting fasteners passing through them, realizing the fixed connection and circumferential synchronous transmission of the handle connecting sleeve and the cover plate connecting post. Rotating the handle grip can drive the handle connecting sleeve to rotate synchronously, thereby driving the cover plate body to complete the outward opening or inward closing action via the cover plate connecting post.

[0007] In another specific embodiment of the present invention, the elastic clamping member is a compression spring. The elastic clamping member is coiled and fitted around the outer periphery of the cover plate connecting post, and the two ends of the elastic clamping member abut and limit the bottom end face of the inner cavity of the handle connecting sleeve and the bottom end face of the positioning groove of the handle connecting sleeve, respectively. The elastic clamping member is normally in a compressed and energy-storing state, continuously applying a pressing force towards the outside of the vehicle to the handle connecting sleeve, the cover plate connecting post, and the cover plate body, so that when the bulletproof cover plate assembly is closed, the cover plate body is tightly against the sealing end face of the outer ring of the firing window to achieve end face sealing. When the handle assembly is pushed outward to drive the cover plate body to push open the window, the handle connecting sleeve compresses the elastic clamping member. After the external force is released, the cover plate body has an automatic closing tendency under the elastic force of the elastic clamping member.

[0008] In another specific embodiment of the present invention, a cover plate mounting step groove is recessed inward on the outer surface of the outer ring of the shooting window of the window frame assembly. The shape and size of the cover plate mounting step groove are adapted to the cover plate body of the bulletproof cover plate assembly. The cover plate body is embedded and housed in the cover plate mounting step groove, and the bottom of the cover plate mounting step groove is the sealing plane for the closed fit of the adapted cover plate body.

[0009] In another specific embodiment of the present invention, a plurality of Y-shaped sealing rings are also fitted at the bottom of the groove of the cover plate mounting step groove, and the plurality of Y-shaped sealing rings are evenly spaced and clamped between the mating end face of the cover plate body and the bottom end face of the groove of the cover plate mounting step groove.

[0010] In another specific embodiment of the present invention, a connecting post positioning hole is provided on the outer ring of the shooting window of the window frame assembly corresponding to the location of the cover plate connecting post; the connecting post positioning hole is provided through the thickness direction of the outer ring of the shooting window, the cover plate connecting post passes through the connecting post positioning hole, and a shooting window outer ring sleeve is fitted in the connecting post positioning hole. The shooting window outer ring sleeve is snapped and covered in the hole wall of the connecting post positioning hole and is used to prevent the cover plate connecting post from directly contacting the shooting window outer ring.

[0011] In a further specific embodiment of the present invention, the window frame assembly further includes a plurality of assembly fixing screws. The outer ring and inner ring of the shooting window are arranged in a corresponding fit, and the plurality of assembly fixing screws are passed through the corresponding mounting holes of the outer ring and inner ring of the shooting window. The outer ring and inner ring of the shooting window are detachably assembled and connected by locking the assembly fixing screws. Flat washers are installed on the assembly fixing screws for anti-loosening.

[0012] In a further specific embodiment of the present invention, a plurality of rubber gaskets are provided around the periphery of the window frame assembly, the rubber gaskets being a full-circle sealing structure; and the plurality of rubber gaskets are clamped and assembled between the outer ring of the shooting window, the inner ring of the shooting window and the special vehicle mounting substrate.

[0013] The beneficial effects of this invention, employing the aforementioned structure, are as follows: First, this technical solution abandons the traditional simple snap-fit ​​limiting structure and adopts a rigid connection method where the handle assembly and the cover plate connecting post are radially locked. Combined with the continuous pre-tightening of the elastic clamping component and the limiting cooperation of the cover plate stepped groove, a fully stable locking structure is formed. When the cover plate body is subjected to bullet impact or heavy object impact, it will not loosen or fall off, maintaining stable bulletproof and riot-proof performance throughout, effectively ensuring the operational safety of special vehicle drivers and passengers. Second, this invention adopts a multi-layered sealing and flexible buffer structure, taking into account both sealing, dustproofing, waterproofing, and component... In terms of protection, the device features a Y-shaped sealing ring to achieve a seal on the end face of the cover plate, and a full-circle rubber gasket between the window frame and the vehicle body substrate to fill the assembly gap, forming a multi-layered three-dimensional sealing system. This effectively prevents rainwater and sand from seeping into the vehicle, avoiding corrosion of internal wiring and aging of the interior, and improving the adaptability of the vehicle to complex operating conditions and the durability of the equipment. Furthermore, this invention optimizes the opening and closing structure and assembly form. The window can be quickly opened and closed by using an inner rotating handle assembly inside the vehicle. The operation is simple and convenient, and the emergency response speed is fast. Combined with the automatic closing characteristic of the elastic element, it can perfectly adapt to the rapid operation requirements of emergency response. Attached Figure Description

[0016] The following will provide a detailed description by way of embodiments. However, the description of the embodiments is not intended to limit the present invention. Any formal but not substantive equivalent transformations made based on the concept of the present invention should be considered within the scope of the present invention.

[0017] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back refer to the current situation. Figure 1 The context refers to the location and state of the object, and therefore should not be construed as a specific limitation on the technical solution provided by this invention.

[0018] Please see Figures 1 to 3 This invention illustrates an outward-protruding bulletproof firing window for special vehicles, comprising: a window frame assembly 1, which includes an outer ring 11 and an inner ring 12 of the firing window. The outer ring 11 and the inner ring 12 are respectively located on the outer and inner sides of the firing window of the special vehicle and are coaxially overlapped. The window frame assembly 1 serves as an integral mounting base, consisting of the coaxially overlapped outer ring 11 and inner ring 12. The outer ring 11 is located on the outer side of the vehicle, and the inner ring 12 is located on the inner side of the vehicle's cabin. The double-layer ring alignment and fitting structure effectively improves the overall assembly flatness and structural stability, providing a precise installation reference for other components; a bulletproof cover assembly 2, which is housed on the outer ring 11 of the firing window; and a handle assembly 3, which passes through the window frame assembly 1 from the inner side of the special vehicle's cabin and is fixedly connected to the bulletproof cover assembly 2 and capable of carrying... The bulletproof cover assembly 2 is rotated and is fully housed and embedded inside the outer ring 11 of the firing window, without occupying additional external space. In actual use, the driver and passengers can rotate the handle assembly 3 at a limited angle inside the cabin to push the bulletproof cover assembly 2 outward to open the window, meeting the needs of shooting, ventilation, observation, and internal and external communication. Reverse rotation will push the bulletproof cover assembly 2 inward to close, quickly restoring the bulletproof and riot protection state. It is easy to operate and has integrated functions. An elastic clamping member 4 is also shown. The elastic clamping member 4 abuts against the outer ring 11 of the firing window and the handle assembly 3, and continuously applies a clamping preload to the handle assembly 3 and the bulletproof cover assembly 2 under normal conditions, so that the bulletproof cover assembly 2 and the outer ring 11 of the firing window remain closed. By rotating the handle assembly 3 at a limited angle, the bulletproof cover assembly 2 is pushed outward to open or pulled inward to close, thereby realizing the opening and closing of the firing window of the special vehicle. The shooting window has a compact and highly integrated structure, making it suitable for installation on the side walls of various police and escort vehicles.

[0019] In this embodiment, the aforementioned handle assembly 3 includes a handle grip 31 and a handle connecting sleeve 32 connected to the handle grip 31. The handle grip 31 is located inside the special vehicle cabin, corresponding to the inner side of the inner ring 12 of the aforementioned firing window. The aforementioned handle connecting sleeve 32 is cylindrical and hollow inside, forming a handle connecting sleeve cavity 321. A handle connecting sleeve positioning groove 121 is formed on the inner ring 12 of the aforementioned firing window, corresponding to the position of the handle connecting sleeve 32. The aforementioned handle connecting sleeve 32 can... The device can be inserted into the positioning groove 121 of the handle connecting sleeve and rotate and slide back and forth therein; the aforementioned bulletproof cover plate assembly 2 includes a cover plate body 21 and a cover plate connecting post 22 connected to the cover plate body 21. The aforementioned cover plate connecting post 22 is adapted to and placed in the inner cavity 321 of the aforementioned handle connecting sleeve. After the aforementioned cover plate connecting post 22 and handle connecting sleeve 32 are inserted and positioned, they are radially locked and fixed by the connecting fasteners 221 passing through both, thereby realizing the connection between the handle connecting sleeve 32 and the cover plate connecting post 22. The fixed connection and circumferential synchronous transmission; rotating the aforementioned handle 31 can drive the handle connecting sleeve 32 to rotate synchronously, and then drive the cover plate body 21 to complete the outward pushing to open the window or the inward closing action through the cover plate connecting post 22; and the aforementioned handle connecting sleeve 32 and cover plate connecting post 22 are rigidly fixed to ensure that there is no relative sliding or loosening in the circumferential direction. This plug-in locking synchronous transmission structure has high transmission accuracy and high structural strength, which can effectively avoid the transmission jamming and free rotation failure problems that occur during long-term opening and closing. When the operator rotates the handle 31, it can accurately drive the cover plate body 21 to complete the outward pushing to open the window or the inward closing action. The opening and closing response is fast and the action is stable, which is suitable for emergency rapid operation scenarios.

[0020] Furthermore, the aforementioned elastic clamping member 4 is a compression spring. This elastic clamping member 4 is coiled and fitted around the outer periphery of the aforementioned cover plate connecting post 22. Both ends of the elastic clamping member 4 abut against and limit the bottom end face of the inner cavity of the handle connecting sleeve 32 and the bottom end face of the groove of the handle connecting sleeve positioning groove 121, respectively. Under normal conditions, the aforementioned elastic clamping member 4 is always in a compressed and energy-storing state, continuously applying a pressing force towards the outside of the vehicle to the aforementioned handle connecting sleeve 32, cover plate connecting post 22, and cover plate body 21. This ensures that when the bulletproof cover plate assembly 2 is closed, the aforementioned cover plate body 21 tightly adheres to the sealing end face of the outer ring 11 of the aforementioned firing window, thereby achieving end face sealing. When the aforementioned handle assembly 3 is pushed outwards, causing the aforementioned cover plate body 21 to push open the window, the aforementioned handle connecting sleeve 32 compresses the elastic clamping member 4. After releasing the external force, the elastic clamping member 4... Under the action of elastic force, the cover body 21 has an automatic closing tendency. That is, when the external thrust is removed, the aforementioned elastic clamping member 4 releases potential energy, which can drive the cover body 21 to automatically return to its position and close, realizing the automatic window reset function. This effectively avoids the problem of protection failure and water and dust ingress caused by failure to close the window in time after opening, and greatly improves the safety and convenience of using the equipment.

[0021] Please continue reading Figure 2 Please see Figure 1 On the outer surface of the outer ring 11 of the shooting window of the aforementioned window frame assembly 1, a cover plate mounting step groove 111 is recessed inward. The shape and size of the cover plate mounting step groove 111 are adapted to the cover plate body 21 of the aforementioned bulletproof cover plate assembly 2. The aforementioned cover plate body 21 is embedded and housed in the cover plate mounting step groove 111, and the bottom of the cover plate mounting step groove 111 is the sealing plane for the aforementioned adapted cover plate body 21 to close and fit. Compared with the traditional external cover plate structure, this stepped mounting structure has multiple advantages: First, it can... The cover plate body 21 forms an all-round limiting mechanism. When the cover plate body 21 is impacted by bullets or hard objects, it relies on the stepped groove wall to limit and block the impact. With the help of the locking structure, the problem of the cover plate falling off or loosening is completely eliminated, and the reliability of bulletproof protection is greatly improved. Secondly, the cover plate body 21 is embedded in the vehicle, with no protruding structure on the outside of the vehicle. The shape is flat and regular, which optimizes the appearance of the vehicle modification. At the same time, it can reduce wind resistance and avoid outdoor impact damage. Thirdly, it can ensure the fitting accuracy and provide a good installation foundation for the subsequent sealing structure, thereby improving the overall sealing effect from a structural point of view.

[0022] In this embodiment, multiple Y-shaped sealing rings 112 are also installed at the bottom of the aforementioned cover plate mounting step groove 111. The multiple Y-shaped sealing rings 112 are evenly spaced and clamped between the mating end face of the cover plate body 21 and the bottom end face of the cover plate mounting step groove 111. The Y-shaped sealing rings 112, which are evenly arranged at multiple points, have a wider sealing coverage and more uniform force. After closing, they can fully fill the tiny assembly gap between the cover plate body 21 and the window frame, achieving all-round sealing of the end face. The Y-shaped sealing rings 112 have good elastic deformation ability and wear resistance and aging resistance. They are not easy to deform and fail under long-term pressure. They can effectively prevent rainwater and outdoor dust from seeping into the cabin through the window gaps, avoid corrosion of the vehicle's wiring, aging of the interior, and dust accumulation in the equipment, greatly improve the vehicle's adaptability to complex and harsh working conditions, extend the service life of the vehicle's equipment, and ensure a clean and dry interior environment.

[0023] Furthermore, a connecting post positioning hole 113 is provided on the outer ring 11 of the shooting window of the aforementioned window frame assembly 1, corresponding to the arrangement position of the aforementioned cover plate connecting post 22. The aforementioned connecting post positioning hole 113 is provided through the thickness direction of the outer ring 11 of the shooting window, and the aforementioned cover plate connecting post 22 passes through the connecting post positioning hole 113. The outer ring sleeve 114 of the shooting window is installed in the aforementioned connecting post positioning hole 113. The aforementioned outer ring sleeve 114 of the shooting window is snapped and covered in the hole wall of the connecting post positioning hole 113 and is used to isolate the cover plate connecting post 22 from direct contact with the outer ring 11 of the shooting window. This isolation structure can effectively solve the defects of metal rigid collision and direct stress transmission in traditional products. When high-frequency impact vibration is generated by gun shooting or bump stress is generated by vehicle driving, the outer ring sleeve 114 of the shooting window can play a buffer isolation role.

[0024] Please continue reading Figures 1 to 3 The aforementioned window frame assembly 1 also includes multiple assembly fixing screws 13. The outer ring 11 and inner ring 12 of the shooting window are arranged vertically and fitted together, and the multiple assembly fixing screws 13 pass through the corresponding mounting holes of the outer ring 11 and inner ring 12 of the shooting window. The outer ring 11 and inner ring 12 of the shooting window are detachably connected by locking the assembly fixing screws 13. Flat washers are installed on the assembly fixing screws 13 to prevent loosening. The multiple sets of assembly fixing screws 13 pass through the corresponding mounting holes of the outer ring 11 and inner ring 12 of the shooting window to achieve locking and fixation, forming a detachable integrated window frame structure. This assembly method of separate assembly and screw locking is simple to assemble, has precise alignment, does not require complex welding processes, and has high processing and assembly efficiency.

[0025] Please see Figure 2 And please combine Figure 1 and Figure 3 Multiple rubber gaskets 5 are also provided around the aforementioned window frame assembly. These rubber gaskets 5 are integral sealing structures. The multiple rubber gaskets 5 are clamped and assembled between the outer ring 11 and inner ring 12 of the shooting window and the special vehicle mounting base material. The integral rubber gaskets 5 have no splicing gaps and strong sealing continuity, completely filling the assembly gap between the window frame and the vehicle body base material, forming a second layer of three-dimensional sealing protection system. This, together with the Y-shaped sealing ring 112 on the window end face, forms a double sealing protection system. This structure can completely prevent rainwater and sand from seeping into the vehicle interior through the assembly gap between the window frame and the vehicle body, comprehensively improving the overall vehicle sealing performance. Simultaneously, the rubber gaskets 5 have a buffering and shock-absorbing function, weakening the rigid vibration between the window frame and the vehicle body, reducing driving noise, and further improving the overall vehicle operating stability and driving comfort.

[0026] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0027] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
