Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for communication equipment, and in particular to an anti-jamming communication device mounted on an armed escort vehicle. Background Technology

[0002] As special-duty vehicles, armed escort vehicles need to maintain real-time and stable communication during missions to ensure the accurate transmission of mission instructions and the timely reporting of emergencies. Due to the special nature of escort missions, vehicles often need to travel at high speeds on unpaved roads or urban roads with complex road conditions, which places extremely high demands on the installation stability and shock resistance of vehicle-mounted communication equipment.

[0003] However, most existing vehicle-mounted communication equipment mounting devices use rigid bolt connections or simple mechanical clamping structures. While this traditional mounting method may meet requirements when the vehicle is traveling smoothly, its structural defects become apparent when the vehicle encounters severe bumps or continuous vibrations. Due to the lack of an effective buffering and energy absorption mechanism, the vertical impact force from the road surface is transmitted directly to the communication equipment body without any attenuation.

[0004] Such continuous hard impacts can have two serious consequences: First, high-frequency vibrations can easily cause rigid connection structures to gradually loosen, causing the equipment to shift or even fall off during operation; second, strong physical vibrations can directly affect the delicate electronic components inside the equipment, causing solder joints to loosen, poor contact, or core modules to shift, thereby generating serious physical signal interference or even communication interruption. This is an unacceptable safety hazard for armed escort missions with extremely high security requirements.

[0005] Therefore, this utility model proposes an anti-jamming communication device for armed escort vehicles to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides an anti-interference communication device for armed escort vehicles, which aims to improve the structural defects of existing armed escort vehicles during complex road conditions, such as communication equipment falling off due to insecure fixing, and the lack of an effective buffer mechanism causing severe vibration that damages internal components, resulting in physical signal interference or interruption.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an armed escort vehicle-mounted anti-interference communication device, comprising: equipment, positioning mechanism and shock absorption mechanism; and a locking block fixedly connected to the left and right side walls of the equipment.

[0008] The positioning mechanism, serving as an installation and locking platform for the equipment, includes a first fixing plate. A first fixing column is fixedly connected to the top surface of the first fixing plate. A first fixing block is slidably connected to the outer surface of the first fixing column. A second fixing block for limiting the position is rotatably connected to the end of the first fixing column. The first fixing block is configured to move along the first fixing column below the second fixing block. A threaded rod is threadedly connected to the inside of the first fixing plate. A handwheel for the operator to rotate is fixedly connected to the top end of the threaded rod, and a third fixing block is rotatably connected to the bottom end. The third fixing block is disposed inside the first fixing block.

[0009] Furthermore, the positioning mechanism drives the threaded rod and the third fixing block to move downward by rotating the handwheel, thereby driving the first fixing block to clamp the card block; the shock absorption mechanism is located below the positioning mechanism, and the shock absorption mechanism includes a shock absorption plate, a third fixing plate is fixedly connected to the top surface of the shock absorption plate, dampers are fixedly connected to both sides of the third fixing plate, the dampers are energy dissipation elements, a guide rod is fixedly connected to the output end of the dampers, a slider is slidably connected to the outer surface of the guide rod, a connecting plate is fixedly connected to the slider, and a spring is connected between the two connecting plates; a second fixing column is rotatably connected to the top of the connecting plate, a second fixing plate is fixedly connected to the top of the second fixing column, and the second fixing plate is fixedly connected to the bottom surface of the first fixing plate, thereby forming an integral linkage buffer structure.

[0010] Preferably, an antenna is fixedly connected to the top surface of the device, a display screen is provided on the front surface of the device, and a knob is provided on one side of the display screen on the front surface of the device; the antenna is used to transmit wireless signals to the display screen for data display, and the knob is used to adjust the volume or frequency band function of the device.

[0011] Preferably, the second fixing block is disposed at the top of the first fixing post, and the outer diameter of the second fixing block is designed to be larger than the diameter of the first fixing post, thereby forming a physical blocking structure to prevent the first fixing block from detaching from the first fixing post during movement.

[0012] Preferably, the third fixing block and the first fixing block are engaged by an inclined surface or a spiral surface. This structural engagement allows the downward vertical movement of the third fixing block under the drive of the thread to be converted into the inward rotation or horizontal displacement of the first fixing block, thereby achieving a strong clamping of the clamping block.

[0013] Preferably, the two ends of the spring are fixedly connected to the opposite sidewalls of the connecting plates on both sides. When the first fixed plate moves the second fixed plate downward due to the force, the inclined connecting plate moves along the spring to both ends and stretches the slider on the guide rod, thereby converting the vertical impact into horizontal movement.

[0014] Preferably, the damper is configured to generate reverse resistance when the connecting plate drives the slider to move, so as to slow down the movement trend of the connecting plate and absorb the impact force, thereby achieving the shock absorption effect.

[0015] Preferably, the shape of the card block is adapted to the shape of the clamping part of the first fixing block, and the device is fixed above the first fixing plate by the embedded cooperation of the card block and the first fixing block.

[0016] Preferably, the shock absorber has mounting structures at both ends for fixed connection with the vehicle body. The second fixing plate, the second fixing column, the connecting plate, the slider and the spring together constitute a linkage-linked shock absorber assembly, which realizes the conversion and absorption of vibration energy through the coordinated action of multiple linkages.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a positioning mechanism, the threaded rod drives the internal fixed block with a conical driving surface to move downward, and then the inclined wedge-shaped cooperation pushes the external fixed block to generate horizontal displacement to clamp the locking blocks on both sides of the device. This solves the problem that the fixing structure of existing vehicle-mounted communication equipment is prone to loosening or even falling off when the armed escort vehicle is traveling at high speed or on bumpy roads. It achieves the effect of high strength and high stability locking of the device by utilizing the self-locking characteristics of the thread and the force amplification principle of the inclined plane, ensuring physical safety during transportation.

[0019] 2. In this utility model, by setting a shock-absorbing mechanism at the bottom, the inclined connecting plate and the slider assembly are used to convert the vertical impact force transmitted by the vehicle body into a horizontal mechanical motion that pushes the slider to slide along the guide rod. The energy is absorbed by the elastic extension and contraction of the spring and the fluid resistance of the damper. This solves the problem that the severe vibration of the vehicle is directly transmitted to the communication equipment, causing damage to internal precision electronic components, loose solder joints or signal transmission interruption. It achieves excellent buffering and shock absorption effect, realizes physical anti-interference, and ensures the stability of communication quality.

[0020] 3. In this utility model, by setting the card blocks on both sides of the equipment and the U-shaped card slots on the positioning mechanism for precise matching, and by setting the anti-slip texture on the surface of the handwheel, the problems of difficult alignment, poor operation feel, or slight shaking of the equipment after clamping are solved in the existing devices during emergency installation. The technical effects of convenient operation, accurate alignment and multi-directional stable positioning are achieved, which improves the efficiency and reliability of equipment maintenance in escort missions.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4This utility model provides an anti-interference communication device for armed escort vehicles, which aims to solve the structural defects of existing armed escort vehicles during complex road conditions, such as communication equipment falling off due to insecure fixing, and the lack of an effective buffer mechanism causing severe vibration that damages internal components, resulting in physical signal interference or interruption.

[0030] The armed escort vehicle-mounted anti-jamming communication device is mainly composed of a core communication component, a positioning component for stable locking, and a shock-absorbing component for buffering and absorbing energy. Specifically, it includes device 3, positioning mechanism 1, and shock-absorbing mechanism 2. The positioning mechanism 1 is used to mechanically clamp and fix device 3 to prevent device 3 from shifting or falling off during vehicle operation. The shock-absorbing mechanism 2 is located at the bottom of the positioning mechanism 1 and is used to convert the vertical impact transmitted by the vehicle body into horizontal motion and absorb energy, thereby protecting the stability of device 3 above.

[0031] Specifically, the device 3 serves as the main carrier for communication functions. Its left and right side walls are symmetrically and fixedly connected with locking blocks 108. The shape of the locking blocks 108 is adapted to the shape of the clamping part of the positioning mechanism 1. The device 3 is fixed above the positioning mechanism 1 through the cooperation of the locking blocks 108 and the positioning mechanism 1. The top surface of the device 3 is fixedly connected with an antenna 4. The antenna 4 is used to receive and send wireless signals and transmit the signals to the inside of the device 3 for processing. The front surface of the device 3 is embedded with a display screen 5. The display screen 5 is used to display communication status and data information. The front surface of the device 3 is provided with a knob 6 on one side of the display screen 5. The knob 6 is used for the operator to adjust the volume or frequency band function of the device 3.

[0032] The positioning mechanism 1 serves as the installation platform for the device 3, including a first fixed plate 107 as a bearing base. A first fixed column 103 is fixedly connected to the top surface of the first fixed plate 107. A first fixed block 101 is slidably connected to the outer surface of the first fixed column 103. The first fixed block 101 is configured to perform vertical reciprocating motion along the first fixed column 103 to achieve a clamping action. A second fixed block 102 is rotatably connected to the top of the first fixed column 103. The outer diameter of the second fixed block 102 is larger than the diameter of the first fixed column 103. The second fixed block 102 is located above the first fixed block 101 and is used to limit the upward movement of the first fixed block 101 to prevent the first fixed block 101 from detaching from the first fixed column 103, while also providing rotational support.

[0033] To achieve the drive control of the positioning mechanism 1, the first fixed plate 107 has a threaded hole inside and a threaded rod 105 is threadedly connected to it. The threaded rod 105 passes through the first fixed plate 107, and the top end of the threaded rod 105 extends above the first fixed plate 107 and is fixedly connected to a handwheel 106. The surface of the handwheel 106 is provided with anti-slip texture to increase friction. The bottom end of the threaded rod 105 is rotatably connected to a third fixed block 104. The third fixed block 104 is movably disposed in the internal cavity of the first fixed block 101. The third fixed block 104 and the first fixed block 101 are engaged by an inclined surface, so that the downward movement of the third fixed block 104 driven by the threaded rod 105 can be converted into the inward rotation tendency of the first fixed block 101, thereby driving the first fixed block 101 to clamp the locking block 108.

[0034] The damping mechanism 2 has a damping plate 209 as an integral support base. The damping plate 209 has mounting structures at both ends for fixed connection with the bottom of the vehicle body. A third fixing plate 204 is fixedly connected to the middle of the top surface of the damping plate 209. The third fixing plate 204 is used to provide mounting positions for the damping components on both sides. Damperes 205 are fixedly connected to the left and right side walls of the third fixing plate 204 respectively. The output end of the damper 205 extends horizontally outward and is fixedly connected to a guide rod 207. The guide rod 207 serves as a sliding track, and a slider 208 is sleeved and slidably connected to its outer surface. A connecting plate 202 is fixedly connected to the inner side wall of the slider 208. The connecting plate 202 is inclined and the left and right connecting plates 202 are symmetrically distributed about the central axis of the third fixing plate 204. A spring 206 is connected between the opposite side walls of the two connecting plates 202. The two ends of the spring 206 are fixed to the two connecting plates 202 respectively to provide lateral elastic restoring force.

[0035] Meanwhile, the top of the connecting plate 202 is connected to the positioning mechanism 1 through a transmission component. The top of the connecting plate 202 converges and rotates together with the second fixed column 203. The top of the second fixed column 203 is fixedly connected to the second fixed plate 201. The upper surface of the second fixed plate 201 is fixedly connected to the lower surface of the first fixed plate 107 in the positioning mechanism 1. In the assembled state, the second fixed plate 201, the second fixed column 203, the connecting plate 202, the slider 208, and the spring 206 together constitute a linkage shock absorption component.

[0036] This linkage structure, which converts vertical motion into horizontal motion, ensures that when the vehicle bumps and the upper first fixed plate 107 is subjected to a vertically downward impact, the pressure can force the inclined connecting plate 202 to deflect at an angle through the second fixed plate 201 and the second fixed column 203. This, in turn, pushes the bottom slider 208 to slide horizontally outward along the guide rod 207. The movement of the slider 208 synchronously stretches the spring 206 and drives the damper 205 to work, converting the destructive impact kinetic energy in the vertical direction into controlled horizontal motion and the elastic potential energy of the spring 206. This significantly attenuates the vibration energy transmitted to the device 3, ensuring the stability of communication.

[0037] As a preferred embodiment, in order to improve the convenience of manual operation and prevent the operator's hand from slipping when adjusting in an emergency, the surface of the handwheel 106 fixedly connected to the top of the threaded rod 105 is provided with an anti-slip texture. The anti-slip texture is a knurled structure or a raised stripe structure, which can effectively increase the friction between the operator's fingers and the surface of the handwheel 106, and ensure that the rotational torque applied to the handwheel 106 can be stably transmitted to the threaded rod 105.

[0038] As another preferred embodiment, in order to efficiently and stably convert the vertical rotational motion of the threaded rod 105 into a horizontal clamping force for the device 3, the outer wall of the third fixing block 104 is constructed with a tapered driving surface, and the inner wall of the corresponding first fixing block 101 is constructed with a force-bearing inclined surface that abuts against the tapered driving surface. Utilizing the wedge-shaped engagement mechanism formed between the tapered driving surface and the force-bearing inclined surface, when the threaded rod 105 drives the third fixing block 104 to move vertically downward, the vertical pressure is converted into a horizontal thrust through the inclined surface, forcibly pushing the first fixing block 101 to produce a horizontal displacement to complete the clamping action.

[0039] As a further preferred embodiment, in order to enhance the limiting stability of the device 3 and prevent the device 3 from still wobbling slightly after being clamped, the first fixing block 101 has a U-shaped groove on the side facing the clamping block 108. The inner wall shape and size of the U-shaped groove are precisely matched with the outer contour size of the clamping block 108, so that the clamping block 108 can be completely embedded in the internal space of the U-shaped groove when it is clamped, thereby using the physical obstruction of the groove wall to assist in limiting the device 3 in multiple directions such as front and back, up and down.

[0040] In addition, in order to adapt to the complex installation environment inside the armed escort vehicle and provide continuous and stable dynamic damping characteristics, the damper 205 is preferably a hydraulic damper 205. The hydraulic damper 205 can provide smooth and continuous reverse fluid resistance when the slider 208 is subjected to force and moves. At the same time, the damping plate 209 has mounting through holes at the four corners. The mounting through holes are used to fit high-strength bolts to firmly install the entire device on the floor inside the vehicle, ensuring that the main body of the device will not be displaced by the bumps of the vehicle.

[0041] Working principle: When using this device for communication operations, first connect the device 3 to the vehicle power system. The antenna 4 starts to receive external signals and transmits the signals to the display screen 5 in real time for display. The operator can adjust the working frequency or volume of the device 3 by using the knob 6 according to actual needs to complete the preparation work before communication.

[0042] When it is necessary to fix the device 3 to cope with the vehicle's driving state, place the device 3 on the first fixing plate 107, adjust the position of the device 3 so that the two side locking blocks 108 are respectively aligned with the first fixing blocks 101 on both sides of the positioning mechanism 1, and the operator turns the handwheel 106 clockwise. The handwheel 106 drives the threaded rod 105 to rotate inside the first fixing plate 107 and generate a downward vertical displacement. The bottom end of the threaded rod 105 pushes the third fixing block 104 to move downward synchronously inside the first fixing block 101.

[0043] By utilizing the wedge-shaped engagement between the tapered driving surface of the outer wall of the third fixing block 104 and the inclined surface of the inner wall of the first fixing block 101, the vertical downward pressure of the third fixing block 104 is converted into a horizontal thrust that forces the first fixing block 101 to move inward. After being subjected to force, the first fixing block 101 slides inward along the first fixing post 103 until the U-shaped slot on the first fixing block 101 is tightly embedded and clamps the locking blocks 108 on both sides of the device 3. At this time, the device 3 is firmly locked on the positioning mechanism 1, and the mechanical fixation is completed.

[0044] When the armed escort vehicle travels on a bumpy road and experiences severe vibrations, the shock absorption mechanism 2 automatically engages. The vertical impact force generated by the vehicle body causes the first fixed plate 107 and the second fixed plate 201 below it to move downward momentarily. The second fixed plate 201 presses down on the inclined connecting plate 202 through the second fixed column 203, forcing the connecting plate 202 to deflect around the second fixed column 203. The bottom end of the connecting plate 202 pushes the slider 208 to slide horizontally outward along the guide rod 207.

[0045] During this process, the horizontal movement of the slider 208 stretches the spring 206 connected between the two connecting plates 202, and the elastic deformation of the spring 206 absorbs most of the vertical impact energy. At the same time, the damper 205 connected to the guide rod 207 generates reverse fluid resistance to the rapid movement of the slider 208, which suppresses the rebound oscillation of the spring 206. Through the rigid locking of the positioning mechanism 1 and the flexible buffering of the shock absorption mechanism 2, the device 3 is effectively prevented from loosening and falling off and physical vibration interference is isolated, ensuring stable transmission of communication signals.
