Description
Technical Field
[0001] This utility model relates to the field of radio jamming device technology, and in particular to a modular radio jamming device. Background Technology
[0002] A radio jamming device is a device used to generate and transmit radio waves at specific frequencies to interfere with or block the communication links, navigation signals, or control signals of other radio devices. Based on electromagnetic compatibility theory, radio jamming devices use techniques such as spectrum overlap and signal modulation to generate interference signals that match the frequency band of the target system. These interference signals can cover and interfere with the communication frequency bands of the target radio devices, including GPS navigation bands and dedicated remote control bands, thereby achieving effective interference with the target devices.
[0003] However, existing technologies have some problems: existing radio jamming devices are usually designed as a whole, making it difficult to repair the device when it is damaged, and some parts of the structure cannot be replaced when they are severely damaged, resulting in the need to replace the device with a new one and wasting resources. Therefore, we propose a modular radio jamming device. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a modular radio jamming device. By designing the radio jamming device in a modular fashion, it is easier to repair or replace each module.
[0005] This utility model is implemented as follows: a modular radio jamming device includes a housing, a fixing groove inside the housing, a signal generating module detachably connected to the fixing groove, a side cover rotatably connected to the inner wall of the fixing groove, a locking component on the housing for fixing the side cover, a power amplifier module fixedly connected inside the housing, a power distribution compartment inside the housing containing a battery, a compartment cover detachably connected to the housing, a groove at the upper end of the housing for detachably connecting a connecting plate, a fixing component on the housing for fixing the connecting plate, and an antenna detachably connected to the connecting plate.
[0006] Optionally, an installation port is provided in the fixing groove, and a connector is fixedly connected to the signal generating module, which is movably connected in the installation port.
[0007] Optionally, the locking assembly includes a locking block, a groove is formed inside the housing, the locking block is slidably connected in the groove, a first spring is fixedly connected to the locking block, the first spring is fixedly connected to the inner wall of the groove, a slider is fixedly connected to the locking block, and a slot is formed on the side cover, the locking block is engaged in the slot.
[0008] Optionally, the fixing component includes a fixing post, which is fixedly connected to the inner wall of the groove, a fixing block is fixedly connected to the fixing post, and a movable block is slidably connected to the fixing post.
[0009] Optionally, the fixing component further includes a fixing head, which is fixedly connected to the lower end of the connecting plate. The fixing head has an clearance groove, and the fixing column is movably connected in the clearance groove. The inner wall of the clearance groove has a slide rail, and a second spring is fixedly connected in the slide rail. A locking block is fixedly connected to the second spring, and the locking block engages with the fixing block.
[0010] Optionally, the fixing assembly further includes a fixing plate, a damper is provided between the fixing plate and the outer shell, a third spring is sleeved on the damper, one end of the third spring is fixedly connected to the inner wall of the outer shell, and the other end of the third spring is fixedly connected to the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model is equipped with a locking component. When the signal generating module is repaired or replaced, the locking block is pushed by pushing the slider to compress the first spring and slide in the groove of the outer shell, causing the locking block to disengage from the slot of the side cover. This allows the locking block to no longer fix the side cover, so the signal generating module can be pulled out. After inserting the new signal generating module, the slider is pushed to retract the locking block into the groove of the outer shell. Then the side cover is closed and the slider is released. The locking block will automatically engage in the slot under the action of the first spring to fix the side cover, preventing the signal generating module from falling off. The locking component facilitates the repair and replacement of the signal generating module. At the same time, the device can also replace the signal generating module with a different transmission frequency to specifically interfere with radio waves, enhancing the applicability and flexibility of the device.
[0014] 2. This utility model is equipped with a fixing component. When installing the antenna, by aligning the fixing head on the connecting plate with the fixing post on the outer shell, and then pressing down on the connecting plate, the connecting plate will push the fixing plate to compress the third spring and move into the groove. At the same time, the locking block inside the fixing head will compress the second spring due to the squeezing force of the fixing head fixed on the fixing post, until the locking block moves to the bottom of the fixing head. The locking block will then be locked at the lower end of the fixing head due to the rebound force of the second spring, and the third spring will also continuously apply pressure to the fixing plate to further fix the connecting plate. After that, the fixing screws are tightened to make the connection between the connecting plate and the fixing plate tight, so as to avoid gaps between the connecting plate and the fixing plate when shaking, which would cause poor contact. This facilitates the replacement of the antenna. When the antenna is hit, the force on the antenna will be transmitted to the fixing plate through the connecting plate. The third spring and damper under the fixing plate will offset the force, reducing the damage to the antenna caused by the impact.

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] like Figures 1 to 6 As shown in the figure, the modular radio jamming device provided by this utility model includes a housing 1. The housing 1 is made of high-strength engineering plastic or aluminum alloy material, which takes into account both lightweight and impact resistance. Its main function is to protect its internal structure. Heat dissipation holes are also provided on the housing 1 for heat dissipation.
[0027] Furthermore, a fixing slot is provided inside the outer casing 1, and a signal generating module 2 is detachably connected to the fixing slot. An installation port is provided in the fixing slot, and a connector 8 is fixedly connected to the signal generating module 2. The connector 8 is movably connected to the installation port. The connector 8 adopts a USB interface, which can quickly connect the signal generating module 2 to the device, thereby facilitating the maintenance and replacement of the signal generating module 2. At the same time, signal generating modules 2 with different transmission frequencies can be used to specifically interfere with radio waves, enhancing the applicability and flexibility of the equipment.
[0028] Furthermore, a side cover 11 is rotatably connected to the inner wall of the fixing groove, and a locking component 7 is provided on the outer shell 1 to fix the side cover 11.
[0029] Furthermore, the locking component 7 includes a locking block 71. A groove is formed inside the outer casing 1. The locking block 71 is slidably connected in the groove. A first spring 72 is fixedly connected to the locking block 71. The first spring 72 is fixedly connected to the inner wall of the groove. A slider 73 is fixedly connected to the locking block 71. Anti-slip texture is provided on the slider 73. A slot is provided on the side cover 11. The locking block 71 is engaged in the slot.
[0030] Specifically, when repairing or replacing the signal generating module 2, by pushing the slider 73, the locking block 71 is driven to compress the first spring 72 and slide in the groove of the outer casing 1, causing the locking block 71 to disengage from the slot of the side cover 11. Thus, the locking block 71 no longer fixes the side cover 11, allowing the signal generating module 2 to be pulled out. After inserting the new signal generating module 2, the slider 73 is pushed to retract the locking block 71 into the groove of the outer casing 1. Then, the side cover 11 is closed, and the slider 73 is released. Under the action of the first spring 72, the locking block 71 will automatically engage in the slot to fix the side cover 11, preventing the signal generating module 2 from falling off.
[0031] Furthermore, a power amplifier module 3 is fixedly connected inside the outer casing 1. A power distribution compartment is provided inside the outer casing 1, and a battery 4 is installed inside the power distribution compartment. The battery 4 is used to power the device. A compartment cover 5 is detachably connected to the outer casing 1. The compartment cover 5 is fixed by screws to facilitate the replacement of the battery 4.
[0032] Specifically, the signal generation module 2 is the core component of the radio jamming device, responsible for generating jamming signals of the required frequency and power. These signals are usually targeted at the frequency range currently used by the target system. The power amplification module 3 is used to enhance the power of the jamming signal to ensure that the signal can cover the target area and achieve the purpose of effective jamming. The power amplification module 3 is a high-power device in the jamming subsystem, and its output power is usually between several hundred watts and several kilowatts. The antenna 10 radiates the amplified jamming signal in a specific direction to improve the jamming efficiency and directionality. The signal generation module 2, the power amplification module 3, the battery 4 and the antenna 10 are all electrically connected. The above are existing mature technologies, which are believed to be well understood by those skilled in the art, and will not be elaborated further here.
[0033] Furthermore, a groove is provided at the upper end of the outer shell 1, and a connecting plate 6 is detachably connected in the groove. A fixing component 9 is provided on the outer shell 1, which is used to fix the connecting plate 6. An antenna 10 is detachably connected to the connecting plate 6. Multiple antennas 10 are provided, and multiple antennas 10 are threadedly connected to the connecting plate 6.
[0034] Specifically, the fixing component 9 includes a fixing post 91, which is fixedly connected to the inner wall of the groove. A fixing block 92 is fixedly connected to the fixing post 91, and a movable block 93 is slidably connected to the fixing post 91.
[0035] Furthermore, the fixing component 9 also includes a fixing head 94, which is fixedly connected to the lower end of the connecting plate 6. The fixing head 94 has an clearance groove, and the fixing post 91 is movably connected in the clearance groove. The inner wall of the clearance groove has a slide rail, and a second spring 95 is fixedly connected in the slide rail. A locking block 96 is fixedly connected to the second spring 95, and the locking block 96 engages with the fixing block 92.
[0036] Furthermore, the fixing assembly 9 also includes a fixing plate 97, and a damper 98 is provided between the fixing plate 97 and the outer shell 1. A third spring 99 is sleeved on the damper 98. One end of the third spring 99 is fixedly connected to the inner wall of the outer shell 1, and the other end of the third spring 99 is fixedly connected to the fixing plate 97.
[0037] Furthermore, a fixing screw 12 is threadedly connected to the middle of the connecting plate 6, and a threaded hole is opened on the fixing plate 97. The fixing screw 12 is threadedly connected to the threaded hole. A contact 13 is fixedly connected to the connecting plate 6, and a corresponding contact groove is opened on the fixing plate 97. The connecting plate 6 is electrically connected to the fixing plate 97 through the contact 13. The contact 13 corresponds one-to-one with the antenna 10, and the two are electrically connected to avoid signal interference. A wire 14 is fixedly connected to the inner wall of the contact groove. The wire 14 is electrically connected to the power amplifier module 3 to ensure that interference signals can be transmitted through the antenna 10.
[0038] Specifically, when installing the antenna 10, the fixing head 94 on the connecting plate 6 is aligned with the fixing post 91 on the outer casing 1, and then the connecting plate 6 is pressed down. The connecting plate 6 will push the fixing plate 97 to compress the third spring 99 and move it into the groove. At the same time, the locking block 96 in the fixing head 94 will compress the second spring 95 due to the squeezing force of the fixing head 94 fixed on the fixing post 91 until the locking block 96 moves to the bottom of the fixing head 94. The locking block 96 will then be locked into the lower end of the fixing head 94 due to the rebound force of the second spring 95. The third spring 99 will also always apply pressure to the fixing plate 97 to further fix the connecting plate 6. Then the fixing screw 12 is tightened to make the connecting plate 6 and the fixing plate 97 tightly connected, so as to avoid gaps between the connecting plate 6 and the fixing plate 97 when shaking, which would cause poor contact.
[0039] Furthermore, when the antenna 10 is impacted, the force on the antenna 10 is transmitted to the fixing plate 97 through the connecting plate 6. The third spring 99 and the damper 98 below the fixing plate 97 will counteract the impact, reducing the damage to the antenna 10 caused by the impact force.
[0040] Furthermore, multiple antennas 10 are connected to the connecting plate 6 by threads. When a single antenna 10 is damaged, it can be quickly replaced. However, when it is necessary to change the type of antenna 10, the entire antenna 10 module needs to be replaced. First, unscrew the fixing screws 12 from the fixing plate 97. Then, by pressing down on the connecting plate 6, the locking block 96 on the connecting plate 6 will move accordingly. When the locking block 96 moves below the movable block 93, the connecting plate 6 is moved upward. The locking block 96 will then drive the movable block 93 to move upward. When the movable block 93 moves to the fixed block 92, the movable block 93 can no longer move and will move along the outer surface of the movable block 93 to the outer surface of the fixed block 92. This will cause the locking block 96 to disengage from the fixed block 92, and the entire antenna 10 module can be removed for replacement.
[0041] The working principle of this utility model is as follows:
[0042] This utility model is equipped with a fixing component 9. When installing the antenna 10, by aligning the fixing head 94 on the connecting plate 6 with the fixing post 91 on the outer shell 1, and then pressing down on the connecting plate 6, the connecting plate 6 will push the fixing plate 97 to compress the third spring 99 and move it into the groove. At the same time, the locking block 96 inside the fixing head 94 will compress the second spring 95 due to the squeezing force of the fixing head 94 fixed on the fixing post 91, until the locking block 96 moves to below the fixing head 94. The locking block 96 will then be engaged by the rebound force of the second spring 95. The lower end of the fixed head 94, and the third spring 99 will always apply pressure to the fixed plate 97 to further fix the connecting plate 6. Then the fixing screw 12 is tightened to make the connecting plate 6 and the fixed plate 97 tightly connected, so as to avoid gaps between the connecting plate 6 and the fixed plate 97 when shaking, which would cause poor contact. At the same time, when the antenna 10 is hit, the force on the antenna 10 will be transmitted to the fixed plate 97 through the connecting plate 6. The third spring 99 and the damper 98 under the fixed plate 97 will cancel it out, reducing the damage of the impact force to the antenna 10.
[0043] When replacing the antenna 10, multiple antennas 10 are connected to the connecting plate 6 by threads. When a single antenna 10 is damaged, it can be quickly replaced. However, when the type of antenna 10 needs to be changed, the entire antenna 10 module needs to be replaced. First, unscrew the fixing screw 12 from the fixing plate 97. Then, by pressing down on the connecting plate 6, the locking block 96 on the connecting plate 6 will move accordingly. When the locking block 96 moves below the movable block 93, the connecting plate 6 is moved upward. The locking block 96 will then drive the movable block 93 to move upward. When the movable block 93 moves to the fixed block 92, the movable block 93 can no longer move and will move along the outer surface of the movable block 93 to the outer surface of the fixed block 92. This causes the locking block 96 to disengage from the fixed block 92, and the entire antenna 10 module can be removed for replacement.
[0044] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
