Description

Technical Field

[0001] The present invention belongs to the technical field of fastening devices, and more specifically, relates to a vehicle-mounted universal gun clamping system and a control method therefor. Background Art

[0002] Firearms are the main weapons used in military operations. When performing tasks, various types of firearms often need to be carried. When the troops are on medium- and long-distance mobile missions, carrying multiple firearms for a long time will pose a challenge to the physical strength of the soldiers. Therefore, the space inside the vehicle and fixed brackets are temporarily used to fix the firearms, so as to save physical strength, reduce the activity constraints and fatigue caused by the firearms to the crew, and improve the mobility of mission execution.

[0003] In the prior art, there are mainly two ways to fix firearms: gun boxes and cabinets, and fixed brackets. Gun boxes and cabinets are mainly used for indoor storage of firearms and cannot move with the soldiers. Fixed brackets can fix one or more firearms and can be installed on vehicles to move with the military vehicles. However, the existing firearm fixing devices are all structures customized according to the external dimensions of the firearms, with a single type of fixed firearm and poor versatility. Moreover, the existing firearm fixing devices all adopt a mechanical locking method, which will affect the convenience of firearm access.

[0004] The invention patent with the application number CN112373402A introduces a multi-purpose firearm fixing bracket that can be installed on a vehicle. It realizes the fixation of the firearm by designing a slidable and adjustable gun seat and gun clip structure according to the external shape of the firearm. When it is necessary to adapt to firearms of different lengths, the distance between the gun seat and the gun clip is adjusted by sliding. Although this structure can adjust the distance between the gun seat and the gun clip through sliders and chutes to adapt to long and short firearms, the structure design of the gun clip is based on a specific type of firearm and is only applicable to a certain type of specific firearm, with poor versatility. Summary of the Invention

[0023] Generally speaking, compared with the prior art, the above technical solution conceived by the present invention can achieve the following beneficial effects:

[0024] 1. A vehicle-mounted universal gun clamping system of the present invention adapts to the outer contours of various guns through the protection range of the protective cover, and slides through the chute to adjust the height to adapt to the lengths of various guns; the buttstock clamping unit adapts to various buttstocks, and the electromagnetic chuck adsorbs and fixes the gun, so that the gun clamping and fixing system of the present invention is not limited by the external structure of the gun, and can realize the fixation of various guns, with good versatility.

[0025] 2. A vehicle-mounted universal gun clamping system of the present invention enables combat personnel to complete the fixation or unlocking of the gun by simply performing an action of opening or closing the protective cover. Through the gun clamping and fixing system of the present invention, the combat work of accessing the gun is made more convenient and fast, improving the combat efficiency.

[0026] 3. A vehicle-mounted universal gun clamping system of the present invention slides the buttstock clamping block along the second guiding groove and cooperates with the fixed buttstock clamping block to clamp the bottom of the buttstock, which can effectively prevent the buttstock from moving upward when the vehicle body vibrates; further, when the buttstock made of wood or engineering plastic cannot be adsorbed and fixed by the second electromagnetic chuck, the buttstock clamping unit can still firmly fix the buttstock, enabling the gun clamping and fixing system to fix various guns.

[0027] 4. A vehicle-mounted universal gun clamping system of the present invention is provided with a second pressure sensor on the V-shaped bayonet of the fixed buttstock clamping block to detect the clamping pressure and upload the test value to the control unit in real time. When the specified threshold is reached, the control unit controls the motor to stop rotating and lock, completing the clamping work on the bottom of the buttstock, avoiding the situation that the displacement distance of the sliding buttstock clamping block cannot be well controlled, resulting in an inappropriate clamping force on the buttstock.

[0028] 5. A vehicle-mounted universal gun clamping system of the present invention is also provided with an elastic layer outside the V-shaped bayonet to avoid rigid clamping of the buttstock and reduce the damage to the surface of the gun caused by clamping.

[0029] 6. A vehicle-mounted universal gun clamping system of the present invention is provided with a permanent magnet and an exciting coil in the electromagnetic chuck. The current adjustment module selects a positive and negative wire change switch and cooperates with the meshing rotation of the adjusting gear and the rack to shift gears, so as to change the direction of the current input into the exciting coil, magnetize or demagnetize the permanent magnet.

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] As Figure 1-7As shown in the figure, an embodiment of the present invention provides a vehicle-mounted universal gun clamping system, which includes an upper fixed seat 4, a protective cover 5, a tray base 6, a buttstock clamping unit 7, a control unit and a power supply module. The upper fixed seat 4 is slidably arranged on the inner side wall of the vehicle body 1 through a chute 2. The tray base 6 is fixedly arranged on the floor inside the vehicle body 1, directly below the upper fixed seat 4, and a current adjustment module 43 is also arranged on its side. One side of the protective cover 5 is hinged to the upper fixed seat 4. The buttstock clamping unit 7 is arranged on the top of the tray base 6 and includes a fixed buttstock clamping block 71 and a sliding buttstock clamping block 72. Electromagnetic suction cups are respectively arranged on the tray base 6 and the upper fixed seat 4, which can adsorb the gun 8 after being energized. After the gun 8 is placed in the gun clamping and fixing system, the control unit controls its functional units in sequence to clamp different types of guns: close the protective cover 5, and the protective cover 5 controls the current adjustment module 43 to work through gear transmission, and then adjusts the output current to increase the suction force of the electromagnetic suction cup, so as to firmly suck the gun 8. The sliding buttstock clamping block 72 cooperates with the fixed buttstock clamping block 71 under the drive of the motor 73 to clamp the bottom of the buttstock, avoiding the gun 8 from moving when the vehicle body 1 vibrates. Through the gun clamping and fixing system of the present invention, under the control of the control unit, the combat personnel only need to close or open the protective cover 5 to complete the work of storing or taking the gun 8, with simple and fast operation, improving the combat efficiency; the protection range of the protective cover 5 adapts to the outer contours of various guns 8, and the height is adjusted by sliding through the chute 2 to adapt to the lengths of various guns 8; the buttstock clamping unit 7 adapts to various types of buttstocks, and the electromagnetic suction cup adsorbs and fixes the gun 8, so that the gun clamping and fixing system of the present invention is not limited by the external structure of the gun, and can realize the fixation of various types of guns, with good versatility.

[0040] As Figure 1-2As shown, the slide 2 is fixed on the side wall of the vehicle body 1 and is kept perpendicular to the floor; a slider 3 is slidably arranged in the slide 2, and its top is fixedly connected to the upper fixed seat 4. Driven by the slider 3, the upper fixed seat 4 can be adjusted up and down along the slide 2. In order to prevent the upper fixed seat 4 from moving along the slide 2 when the vehicle body 1 vibrates, resulting in the upper end of the gun 8 being unable to be fixed, a locking threaded hole is penetrated through the slider 3, and a locking screw is provided in the locking threaded hole through a threaded connection. A screw handle is provided on the top of the locking screw, and a locking block is provided at the bottom. The diameter of the locking block is smaller than the groove width of the slide 2. After the height adjustment of the upper fixed seat 4 is completed, the locking screw can push the locking block to move toward the bottom of the slide 2 along the locking threaded hole by turning the screw handle, and contact with the bottom of the groove to form a friction pair, and the upper fixed seat 4 is locked and fixed by converting pressure into friction to prevent it from moving up and down during vibration. For guns 8 of different lengths, the screw handle can be turned in the opposite direction to unlock and adjust the height of the upper fixing seat 4 to adapt to guns of different lengths 8. The tray base 6 is fixedly arranged on the bottom plate in the vehicle body 1, directly below the upper fixing seat 4, the bottom of the butt of the gun 8 is vertically placed on the base 6, and the upper end of the gun body can be kept in a vertical state and contact with the top of the upper fixing seat 4.

[0041] like Figure 3 As shown, the upper fixing seat 4 is provided with a first fixing ear seat 44 on the side thereof, and the upper fixing seat 4 can be fixed on the slider 3 by cooperating with a bolt; a first electromagnetic suction cup 41 is provided on the top thereof, and the first electromagnetic suction cup 41 is electrically connected to the power module, and the control unit controls the power module to supply power to the first electromagnetic suction cup 41 to generate magnetic force, thereby attracting the gun 8. A hinge shaft 42 is also provided on the right side of the top of the upper fixing seat 4, and the protective cover 5 is hinged to the upper fixing seat 4 through the hinge shaft 42, so that it can rotate around the hinge shaft 42.

[0042] The protective cover 5 includes an arc-shaped cover body 51 and a tightening piece 52, wherein the arc width of the arc-shaped cover body 51 is the same as the width of the upper end fixing seat 4, and a hollow portion 511 is provided on the arc-shaped cover body 51, which reduces the weight of the arc-shaped cover body 51 and facilitates the combatants to pull open the protective cover 5. The size of the arc-shaped cover body 51 can be determined according to the maximum outer contour of the gun 8, so that it can be compatible with the fixing of multiple types of guns. The right side of the arc-shaped cover body 51 is connected to the hinge shaft 42, and the left side is provided with a tightening piece 52, which fits with the side of the upper end fixing seat 4 after the protective cover 5 is closed, plays a certain tightening role, and prevents the protective cover 5 from being separated from the upper end fixing seat 4 during vibration. A rack 521 is provided at the bottom of the tightening piece 52, which is engaged with the adjusting gear 431 provided on the current regulating module 43, and can be used to adjust the output of the current regulating module 43 when the protective cover 5 is opened or closed. The current regulating module 43 is fixedly arranged on the left side of the upper end fixing seat 4, and the adjusting knob thereof is fixedly provided with an adjusting gear 431, and the current input to the electromagnetic suction cup is adjusted by rotating the gear 431.

[0043] As Figure 4-5 shown, a second fixed ear seat 65 is provided at the bottom of the side of the tray base 6, and the tray base 6 can be fixed to the inner floor of the vehicle body 1 by bolts. First guide grooves 62 and second guide grooves 63 are symmetrically provided at the top of the tray base 6. Both of them have the same structure and are wedge-shaped grooves with a trapezoidal cross-section, which can be used to guide the sliding of the buttstock block 72 when it slides. A second electromagnetic chuck 61 is provided between the first guide groove 62 and the second guide groove 63, which adsorbs the buttstock after being powered on. A first pressure sensor 64 is further provided on the top of the second electromagnetic chuck 61, which is communicatively connected to the control unit. When it detects that the firearm 8 is pressing on the top of the second electromagnetic chuck 61, it transmits a signal to the control unit, and the control unit compares the measured pressure value with the set threshold. When the pressure exceeds the set threshold, the control unit controls the power supply module to supply power to the electromagnetic chuck.

[0044] The motor 73 is provided on the left side of the tray base 6, and the central axis of its motor shaft coincides with the central axis of the second guide groove 63. A lead screw shaft 731 is fixedly provided on the motor shaft. After the motor 73 is powered on, it can drive the lead screw shaft 731 to rotate in the second guide groove 63.

[0045] The buttstock clamping unit 7 includes a fixed buttstock clamping block 71 and a sliding buttstock clamping block 72, which are symmetrically arranged on the top of the second electromagnetic chuck 61. The fixed buttstock clamping block 71 is fixedly connected to the top of the second electromagnetic chuck 61, and the sliding buttstock clamping block 72 can slide on the top of the second electromagnetic chuck 61. By approaching each other through the V-shaped clamping openings symmetrically arranged on the adjacent sides of the two, pressure is exerted on the bottom of the buttstock to fix the bottom of the firearm 8. A guide beam 721 and a guide block 722 are provided at the bottom of the sliding buttstock clamping block 72. The guide beam 721 is located in the first guide groove 62, is adapted to the first guide groove 62, can slide in the first guide groove 62, and has the same length as the sliding buttstock clamping block 72, which can support the moving buttstock clamping block 72. The guide block 722 is located in the second guide groove 63, is adapted to the second guide groove 63, and can slide in the second guide groove 63. The guide block 722 is threadedly connected to the lead screw shaft 731. When the lead screw shaft 731 rotates, due to the restriction of the wedge-shaped groove structure of the second guide groove 63, the guide block 722 can only perform a linear displacement along the second guide groove 63. Driven by the guide block 722, the sliding buttstock clamping block 72 slides along the second guide groove 63 and cooperates with the fixed buttstock clamping block 71 to clamp the bottom of the buttstock, which can effectively prevent the buttstock from moving upward when the vehicle body 1 vibrates. Further, when the buttstock made of wood or engineering plastic cannot be adsorbed and fixed by the second electromagnetic chuck 61, the buttstock clamping unit 7 can still firmly fix the buttstock, so that the gun clamping fixing system can fix various types of firearms. To adapt to multiple types of buttstocks and avoid the displacement distance of the sliding buttstock clamping block 72 not being well controlled when the bottom length of the buttstock is different, resulting in an inappropriate clamping force on the buttstock, a second pressure sensor 711 is further provided on the V-shaped clamping opening of the fixed buttstock clamping block 71, which is communicatively connected to the control unit. When the motor 73 drives the lead screw shaft 731 to rotate, pushing the guide block 722 to displace along the second guide groove 63, so that the sliding buttstock clamping block 72 approaches the V-shaped clamping opening of the fixed buttstock clamping block 71 and clamps the bottom of the buttstock tightly. The second pressure sensor 711 detects the clamping pressure and uploads the measured value to the control unit in real time. When the specified threshold is reached, the control unit controls the motor 73 to stop rotating and lock, completing the clamping work on the bottom of the buttstock. By providing the second pressure sensor 711 to detect the clamping pressure and using the sliding adjustment of the sliding buttstock clamping block 72 to adjust the distance between the V-shaped clamping openings, various types of firearms can be adapted. Preferably, an elastic layer 74 is further provided outside the V-shaped clamping opening to avoid rigid clamping of the buttstock and reduce the damage to the surface of the firearm during clamping.

[0046] Such as Figure 6-7As shown in the figure, when the gun clamping and fixing system of the present invention is fixing the firearm 8, the combatant can place the gunstock on the tray base 6 and lean the gun body against the upper fixing seat 4. At this time, the first pressure sensor 64 detects the pressure and transmits the measured value to the control unit. The control unit controls the power supply module to supply power to the electromagnetic chuck. The combatant closes the protective cover 5. At this time, the clamping piece 52 fits against the side of the upper fixing seat 4, and the rack 521 meshes with the adjusting gear 431 to drive it to rotate, adjusting the current output of the current adjusting module 43 to increase the suction force of the electromagnetic chuck and firmly suck the firearm 8. The control unit controls the motor 73 to drive the lead screw shaft 731 to rotate, and the guide block 722 displaces along the second guide groove 63, so that the V-shaped bayonet of the sliding gunstock block 72 and the fixed gunstock block 71 clamps the bottom of the gunstock. The second pressure sensor 711 detects the clamping pressure and transmits the measured value to the control unit in real time. When the specified pressure threshold is reached, the control unit controls the motor 73 to stop rotating and lock, completing the clamping work on the bottom of the gunstock.

[0047] When removing the firearm 8, the combatant opens the protective cover 5. At this time, the rack 521 meshes with the adjusting gear 431 to drive it to rotate, adjusting the current output of the current adjusting module 43 to make the suction force of the electromagnetic chuck disappear. The control unit controls the motor 73 to reverse, and the moving guide block 722 quickly drives the gunstock block 72 to reset, completing the unlocking work. The combatant takes out the firearm 8.

[0048] In the embodiment of the present invention, the combatant only needs to complete an action of opening or closing the protective cover 5 to complete the fixing or unlocking work of the firearm 8. Through the gun clamping and fixing system of the present invention, the combat work of accessing the gun is made more convenient and fast, improving the combat efficiency.

[0049] In the gun clamping and fixing system of the present invention, the power supply module is electrically connected to the vehicle-mounted power supply and supplies power to other electrical components after being controlled by the control unit. To avoid power failure in case of unexpected situations of the vehicle-mounted power supply, backup batteries are respectively provided in the tray base 6 and the upper fixing seat 4, which can supply power when the vehicle-mounted power supply is powered off.

[0050] In the first embodiment of the present invention, an electromagnetic coil is provided inside the electromagnetic chuck. The current adjustment module 43 selects a rotary potentiometer, and the resistance is adjusted by engaging a fixed adjustment gear 431 on its rotation adjustment shaft with a rack 521, so as to increase or decrease the current input to the electromagnetic coil, thereby controlling the suction force of the electromagnetic chuck. When the protective cover 5 is closed, the rack 521 drives the adjustment gear 431 to rotate, reducing the resistance of the rotary potentiometer, increasing the current input to the electromagnetic coil, and increasing the suction force of the electromagnetic chuck, thereby firmly adsorbing the firearm. When the protective cover 5 is opened, the rack 521 drives the adjustment gear 431 to rotate in the reverse direction, increasing the resistance of the rotary potentiometer, reducing the current input to the electromagnetic coil, and the suction force of the electromagnetic chuck disappears, thereby unlocking the firearm and facilitating the combat personnel to take the gun.

[0051] In the second embodiment of the present invention, a permanent magnet and an exciting coil are provided inside the electromagnetic chuck. The current adjustment module 43 selects a positive and negative wire changeover switch, which has forward and reverse gears. The gears are shifted by engaging a fixed adjustment gear 431 on the rotation adjustment shaft with a rack 521 to rotate, so as to change the direction of the current input to the exciting coil and magnetize or demagnetize the permanent magnet. When the protective cover 5 is closed, the rack 521 drives the adjustment gear 431 to rotate, shifting the positive and negative wire changeover switch to the forward gear. By inputting a positive current, the exciting coil magnetizes the permanent magnet. After the magnetization work is completed, the control unit controls the power supply module to stop supplying power to the electromagnetic chuck. At this time, the firearm 8 can be firmly adsorbed by relying on the magnetic force of the permanent magnet itself. When the protective cover 5 is opened, the rack 521 drives the adjustment gear 431 to rotate in the reverse direction, shifting the positive and negative wire changeover switch to the reverse gear, switching the current input direction, inputting a reverse current into the exciting coil, and demagnetizing the permanent magnet by the exciting coil. After the demagnetization work is completed, the control unit controls the power supply module to stop supplying power to the electromagnetic chuck. At this time, the magnetic force on the outer surface of the permanent magnet disappears, and the combat personnel can easily take out the firearm. By providing a permanent magnet and an exciting coil, the magnetization or demagnetization time is short, so that the electromagnetic chuck does not need to continuously connect to the power supply to maintain its working state, can operate continuously without generating heat, greatly extends the working duration of the gun clamping system, and reduces the power supply burden of the combat vehicle.

[0052] The embodiment of the present invention also provides a control method for a vehicle-mounted general firearm clamping system, including the steps:

[0053] S100: The combat personnel place the butt of the gun on the tray base 6, and the gun body leans against the upper fixing seat 4;

[0054] S200: The first pressure sensor 64 detects the pressure and transmits the test value to the control unit, and the control unit controls the power supply module to supply power to the electromagnetic chuck;

[0055] S300: The protective cover 5 closes, the rack 521 drives the adjusting gear 431 to rotate, adjusts the current output of the current adjusting module 43, increases the suction force of the electromagnetic chuck, and firmly sucks the firearm 8;

[0056] S400: The motor 73 drives the lead screw shaft 731 to rotate. The V-shaped bayonet of the sliding buttstock block 72 and the fixed buttstock block 71 clamps the bottom of the buttstock. When the second pressure sensor 711 detects that the clamping pressure reaches the specified pressure threshold, the control unit controls the motor to stop rotating and locks it, completing the fixation of the firearm 8;

[0057] S500: The operator opens the protective cover 5, the rack 521 drives the adjusting gear 431 to rotate, adjusts the current output of the current adjusting module 43, and makes the suction force of the electromagnetic chuck disappear;

[0058] S600: The control unit controls the motor 73 to reverse, and the moving guide block 722 quickly drives the buttstock block 72 to reset;

[0059] S700: The operator takes out the firearm 8. When the first pressure sensor 64 detects no pressure, the control unit controls the power supply module to cut off the power of the electromagnetic chuck, completing the work of taking out the firearm 8.

[0060] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
