Description

Technical Field

[0001] The present invention relates to the technical field of vehicle protection, and particularly to a fixing frame for a roof protection net and a vehicle. Background Art

[0002] Most modern wheeled combat vehicles are equipped with protective armor on the front or side of the vehicle body to obtain protection performance. The roof is the weakest part. Without installing an external protection device, it is difficult to escape unscathed when hit by a shell on the top. In addition to traditional shells, drones with hanging capabilities and high-speed diving drones also pose an increasing threat to ground vehicles. Therefore, it is necessary to design a frame on the roof to install a metal net to enhance the protection ability of the vehicle top and reduce the threat of drones and bombs to the vehicle. Summary of the Invention

[0003] To solve the deficiencies in the prior art, the present invention provides a fixing frame for a roof protection net and a vehicle. This frame has a small obstruction to the firing range of the original weapons on the roof, does not interfere with the operation of personnel on the roof equipment, has a simple and reliable structure, is easy to assemble and maintain, realizes lightweight under the premise of ensuring performance, and reduces costs.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] On the one hand, the present invention provides a fixing frame for a roof protection net, including:

[0006] A front frame, installed on the weapon station on the roof and capable of rotating synchronously therewith, for installing a protection net to protect the front part of the roof;

[0007] A rear frame, installed on the roof behind the front frame, for installing a protection net to protect the rear part of the roof;

[0008] There is a movement gap between the front frame and the rear frame.

[0009] As a further optimized solution of the present invention, the front frame includes a support ring, and a plurality of first support legs are circumferentially and spacedly installed below the support ring, and the bottoms of the first support legs are installed on the weapon station.

[0010] As a further optimized solution of the present invention, a notch is provided at the front of the support ring, and both ends of the support ring at the notch extend backward and are connected to form an n-shaped extension part, and a support rod is provided between the extension part and the support ring.

[0011] As a further optimized solution of the present invention, a plurality of first insertion pipes corresponding to the first support legs one by one are circumferentially and spacedly installed at the bottom of the support ring, and the first insertion pipes are detachably connected to the first support legs through pipe joints.

[0012] As a further optimization solution of the present invention, the first support leg is arranged obliquely towards the inner side of the front frame, and the first support leg is arranged to avoid the notch.

[0013] As a further optimization solution of the present invention, the rear frame includes a first rear frame and a second rear frame arranged side by side. The first rear frame includes a first rectangular frame and a plurality of second support legs installed below the first rectangular frame. The second rear frame includes a second rectangular frame and a plurality of third support legs installed below the second rectangular frame. The projection shapes of the first rectangular frame and the second rectangular frame in the front-rear horizontal direction are inverted V-shaped.

[0014] As a further optimization solution of the present invention, a plurality of second insertion tubes corresponding to the second support legs one by one are circumferentially and spacedly installed at the bottom of the first rectangular frame, and a plurality of third insertion tubes corresponding to the third support legs one by one are circumferentially and spacedly installed at the bottom of the second rectangular frame; the second insertion tubes are detachably connected to the second support legs through pipe joints, and the third insertion tubes are detachably connected to the third support legs through pipe joints.

[0015] As a further optimization solution of the present invention, both the second support legs and the third support legs are vertically arranged and are assembled by one or more sections of steel pipes through pipe joints; both the second support legs and the third support legs are fixed to the roof of the vehicle through mounting bases.

[0016] As a further optimization solution of the present invention, the movement gap is more than 5 cm, and the gap between the first rear frame and the second rear frame is 1 - 2 cm; hooks are installed on the pipe joints.

[0017] On the other hand, the present invention also provides a vehicle, including the front frame and the rear frame described above. The front frame is installed on the weapon station on the roof of the vehicle, and the rear frame is installed on the roof of the vehicle behind the weapon station; protective nets are installed on both the front frame and the rear frame.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The fixed frame of the roof protective net and the vehicle proposed by the present invention achieve various beneficial effects through a series of unique technical solutions:

[0020] (1) The front frame is installed on the roof weapon station and can rotate synchronously, without obstruction to the 360° firing range of the weapon. For example, a notch is provided at the front of the support ring, and the first support leg is arranged to avoid the notch, which not only does not affect the up and down shooting angle adjustment of the machine gun, but also ensures that the field of view and angle during the shooting of the weapon station are not limited, guaranteeing the normal use of the vehicle weapon system. The overall frame structure is reasonably designed and does not interfere with the personnel's operation of the roof equipment, ensuring that the personnel can smoothly operate and maintain the roof equipment during the vehicle's combat or mission execution process.

[0021] (2) The main body of the frame is composed of round steel pipes, formed by bending process. The round steel pipes of each section are connected by pipe joints, and the pipe joints, mounting bases, etc. all use mature parts on the market and do not require special processing. For example, the first insertion pipe and the first support leg, the second insertion pipe and the second support leg, and the third insertion pipe and the third support leg are all detachably connected by pipe joints. This connection method makes the operation of the frame during assembly and maintenance simple and convenient, reducing the assembly and maintenance difficulty. The frame can be disassembled and assembled in sections, which not only facilitates transportation and reduces the transportation difficulty, but also meets the needs of the vehicle's later modification and addition. When the roof does not need to be protected, the frame can be disassembled and stored in sections, reducing the occupation of the original space of the vehicle and improving the space utilization efficiency.

[0022] (3) Due to the use of mature standard parts on the market, the cost of special processing is reduced. At the same time, on the premise of ensuring the protection performance, the frame structure is reasonably designed to achieve lightweight, further reducing the material cost and manufacturing cost. The main body of the frame is made of high-strength aluminum alloy round steel pipes, which have both lightweight and impact resistance performance. While reducing the overall weight of the vehicle, it can effectively resist the impact of high-speed metal fragments and small unmanned aerial vehicles, ensuring the safety of the vehicle. The pipe joints and mounting bases are made of stainless steel, improving the corrosion resistance and making it suitable for harsh field environments, extending the service life of the frame.

[0023] (4) The movement gap between the front frame and the rear frame is more than 5 cm, ensuring that there is no interference to the frame when the weapon station rotates; the gap between the first rear frame and the second rear frame is 1 - 2 cm, which not only avoids the risk of foreign objects falling, but also facilitates the installation of the protective net. The hooks are convenient for fixing the protective net: hooks are installed on the pipe joints, and metal rings are prefabricated at the edges of the protective net. The metal rings are buckled with the hooks one by one to ensure that the whole net is evenly stressed, making the installation of the protective net more firm and improving the protection effect.

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the preferred implementation manners of the present invention will be described below in conjunction with specific embodiments. However, it should be understood that the drawings are only for illustrative purposes and cannot be construed as a limitation to this patent; in order to better illustrate this embodiment, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as a limitation to this patent.

[0031] As Figures 1-5 shown, this embodiment proposes a fixed frame for a roof protection net, which includes a front frame 1 and a rear frame 2. Among them, the front frame 1 is installed on the weapon station on the roof and can rotate synchronously therewith, and is used to install the protection net to protect the front part of the roof. The rear frame 2 is installed on the roof behind the front frame 1 and is used to install the protection net to protect the rear part of the roof. There is a movement gap between the front frame 1 and the rear frame 2.

[0032] Specifically, the frame body is composed of several sections of circular steel pipes, and the required shape is obtained through the bending process. Each section of the circular steel pipe is quickly disassembled and assembled through various pipe joints 3, achieving the convenience of assembly and maintenance. The circular steel pipes, pipe joints 3 and installation bases 207 can all be purchased as mature standard parts, with relatively low costs. Since the frame can be disassembled and assembled in sections, the transportation difficulty is low and the installation is convenient. Therefore, it can be installed when the vehicle leaves the factory or can be retrofitted later to meet the needs of the aftermarket modification. In scenarios where the roof does not need to be protected, the frame can be disassembled and assembled in sections for storage, reducing the occupation of the original space. The frame body is made of high-strength aluminum alloy circular steel pipes (wall thickness 2-3mm), combining lightweight and impact resistance; the pipe joints 3 and installation bases 207 are made of stainless steel to enhance corrosion resistance and are suitable for harsh outdoor environments.

[0033] In some examples, the front frame 1 includes a support ring 11. A plurality of first support legs 12 are circumferentially and spacedly installed below the support ring 11. The bottom of the first support legs 12 extends horizontally inward and is formed and pressed into a plate and installed on the weapon station through bolts.

[0034] Specifically, a notch 13 is provided at the front of the support ring 11. Both endpoints of the support ring 11 located at the notch 13 extend backward and are connected to form an n-shaped extension 14. A support rod 15 is provided between the extension 14 and the support ring 11. The front frame 1 can rotate 360° with the weapon station, without blocking the firing range of the machine gun. The design of the notch 13 does not affect the adjustment of the up and down firing angles of the machine gun. The support rod 15 is welded between the extension 14 and the support ring 11 to enhance the torsional resistance of the front frame 1.

[0035] A plurality of first insertion tubes 16 corresponding to the first support legs 12 one by one are circumferentially and spacedly installed at the bottom of the support ring 11. The first insertion tubes 16 are detachably connected to the first support legs 12 through the pipe joints 3. The upper structure of the front frame 1: the support ring 11, the extension 14, the support rod 15 and the first insertion tubes 16 can be welded into an assembly. The whole is inserted into the lower first support legs 12 through the pipe joints 3, improving the assembly convenience.

[0036] The first support legs 12 are arranged obliquely towards the inside of the front frame 1, and the first support legs 12 and the notch 13 are arranged in an avoidance manner. When installing the front frame 1, the first support legs 12 are fixed to the preset installation hole positions at the top of the weapon station through bolts, and the inclination angle of the support legs is adjusted so that the notch 13 is facing the firing direction of the weapon station. Align the first insertion tubes 16 at the bottom of the support ring 11 with the upper ends of the first support legs 12. After insertion, lock them through the pipe joints 3 to form a stable triangular support structure.

[0037] In some examples, the rear frame 2 includes a first rear frame 21 and a second rear frame 22 arranged side by side. The first rear frame 21 includes a first rectangular frame 201 and a plurality of second support legs 202 installed below the first rectangular frame 201. The second rear frame 22 includes a second rectangular frame 203 and a plurality of third support legs 204 installed below the second rectangular frame 203. The projected shapes of the first rectangular frame 201 and the second rectangular frame 203 in the front-rear horizontal direction are inverted V-shaped. The inverted V-shaped design (i.e., the first rectangular frame 201 and the second rectangular frame 203 are inclined downward to the left and right sides respectively) can prevent falling objects from remaining on the protective net.

[0038] Specifically, a plurality of second insertion tubes 205 corresponding to the second support legs 202 one by one are installed at intervals in the circumferential direction of the bottom of the first rectangular frame 201, and a plurality of third insertion tubes 206 corresponding to the third support legs 204 one by one are installed at intervals in the circumferential direction of the bottom of the second rectangular frame 203; the second insertion tubes 205 are detachably connected to the second support legs 202 through pipe joints 3, and the third insertion tubes 206 are detachably connected to the third support legs 204 through pipe joints 3. The upper structure of the first rear frame 21: the first rectangular frame 201 and the second insertion tubes 205 can be assembled into a total assembly, and the whole is inserted into the lower second support legs 202 through the pipe joints 3, improving the assembly convenience. Similarly, the upper structure of the second rear frame 22: the second rectangular frame 203 and the third insertion tubes 206 can be assembled into a total assembly, and the whole is inserted into the lower third support legs 204 through the pipe joints 3, improving the assembly convenience. The insertion tubes and the support legs adopt laser cutting technology to ensure the interface accuracy and avoid assembly deviation.

[0039] Both the second support legs 202 and the third support legs 204 are vertically arranged and are assembled by one or more sections of steel pipes through pipe joints 3; both the second support legs 202 and the third support legs 204 are fixed to the roof of the vehicle through mounting bases 207. Among them, both the first rectangular frame 201 and the second rectangular frame 203 are assembled by multiple sections of steel pipes through pipe joints 3, realizing the convenience of frame disassembly and assembly.

[0040] In some examples, the movement clearance is 5 - 10 cm, allowing the frame to have no interference when the weapon station rotates 360°. The clearance between the first rear frame 21 and the second rear frame 22 is 1 - 2 cm. If the clearance is too large, there is a risk of foreign objects falling. If the clearance is too small, it is inconvenient to install the protective net. A hook 4 is installed on the pipe joint 3, which is convenient for fixing the protective net.

[0041] Based on a general inventive concept, an embodiment of the present invention further provides a vehicle, including a front frame 1 and a rear frame 2. The front frame 1 is installed on a weapon station on the roof, and the rear frame 2 is installed on the roof behind the weapon station; protective nets are installed on both the front frame 1 and the rear frame 2. The protective net is a 304 stainless steel woven net (mesh diameter ≤ 5 cm), which can resist the impact of high-speed metal fragments and small unmanned aerial vehicles. The metal rings prefabricated at the edges of the protective net are buckled one by one with the hooks 4 on the frame. The distance between the hooks 4 is 20 cm to ensure uniform force on the entire net.

[0042] According to the description and drawings of the present invention, those skilled in the art can easily manufacture or use a fixed frame for a roof protective net and a vehicle of the present invention, and can achieve the positive effects recorded in the present invention.
