Technical Field

[0002] This application relates to an electronic device, a frequency jammer, and a wireless signal shielding system. Background Technology

[0003] Frequency jamming devices, such as frequency jammers, are commonly used in scenarios such as bomb disposal, counter-terrorism, technical reconnaissance, and preventing cheating in examinations. By scanning frequencies, they generate appropriate interference signals to interfere with the signals of illegal devices, thereby shielding the communication signals of illegal devices within a certain spatial range.

[0004] If the frequency jammer places the antenna outside the main unit, the antenna is usually directly connected to the main unit via a hinge to allow the antenna to rotate relative to the main unit. However, when the antenna is in operation, it usually needs to be rotated above the main unit. How to keep the antenna stable during operation is a problem that urgently needs to be solved.

[0025] Frequency jammers in related technologies typically consist of a main unit and an antenna. The antenna is usually directly connected to the main unit via a hinge to allow it to rotate relative to the main unit. However, when the antenna is in operation, it typically needs to be rotated above the main unit. Maintaining antenna stability during operation is a problem that urgently needs to be solved.

[0026] In view of the above-mentioned problems, the present invention provides an electronic device, a frequency jammer and a wireless signal shielding system. By improving the setting position and structure of the rotating shaft assembly, the antenna assembly can be kept stable in the working state.

[0027] Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the overall structure of an electronic device provided according to some embodiments of the present invention. Figure 2 is a schematic diagram of the connection between the hinge assembly and the antenna assembly provided according to some embodiments of the present invention. One embodiment of the present invention first provides an electronic device, which can be used indoors or outdoors and is a device capable of transmitting and receiving electromagnetic waves or transmitting interference signals, such as a frequency jammer, weather radar, phased array radar, etc. The electronic device may include a main unit 100, a hinge assembly 300, and an antenna assembly 200.

[0028] The main unit 100 has a support portion 101, a rotating shaft assembly 300 is rotatably disposed on the main unit 100, and an antenna assembly 200 is connected to the rotating shaft assembly 300. When the antenna assembly 200 rotates to a preset angle, at least a portion of the structure of the rotating shaft assembly 300 abuts against the support portion 101.

[0029] Understandably, the host 100 is used, for example, to generate radio frequency signals, while the antenna assembly 200 is used to transmit the radio frequency signals. Of course, the antenna assembly 200 can also be used to receive radio signals in a preset frequency band, such as those of a base station, and transmit the received radio signals to the host 100 for analysis and processing.

[0030] Since the antenna assembly 200 is movably connected to the host 100 via the pivot assembly 300, it means that when the antenna assembly 200 is not needed, it can be moved to a non-working position relative to the host 100 (also understood as a closed or non-working state) via the pivot assembly 300. When the antenna assembly 200 is needed, it can be moved to a working position relative to the host 100 (also understood as an unfolded state) via the pivot assembly 300. This configuration allows for easy rotation of the antenna assembly 200 relative to the host 100.

[0031] When the antenna assembly 200 rotates to a preset angle, such as the working position, or to any other desired angle, at least a portion of the structure of the hinge assembly 300 abuts against the host 100. This method of securing the antenna assembly 200 by abutting against the host 100 improves the stability of the antenna assembly 200 when it is in the working position. In this example, the working position is, for example, when the hinge assembly 300 is rotated to the top of the host 100, and the antenna assembly 200 is positioned above the host 100. Of course, the top of the host 100 usually refers to the side of the electronic device facing the sky when it is in operation.

[0032] More specifically, in this example, the top of the host 100 is provided with a support portion 101, which is used to support the rotating shaft assembly 300. The support portion 101 is, for example, a plane, inclined surface, or arc surface formed on the host 100, or the support portion 101 includes several block-shaped structures distributed at different positions on the top of the host 100, as long as they can support the antenna assembly 200 when it rotates to a preset angle. The rotating shaft assembly 300 includes, for example, a rod or plate adapted to and abutting against the support portion 101. When the support portion 101 is a plane formed on the host 100 (as shown in Figure 2), when the antenna assembly 200 moves to the working position with the rotating shaft assembly 300, the rod or plate of the rotating shaft assembly 300 rotates to a position parallel to the plane and abuts against the plane, thereby enhancing the stability of the antenna assembly 200 in the working position.

[0033] Alternatively, as shown in Figure 3(a), when the support portion 101 is an inclined surface formed on the host 100, the inclined surface can tilt downwards at a certain angle from the end opposite to the rotation origin of the pivot assembly 300, and the rod or plate of the pivot assembly 300 also has the same tilt angle as the inclined surface. When the inclined surface abuts against the rod or plate of the pivot assembly 300, it can also stabilize the antenna assembly 200, and can further prevent the pivot assembly 300 and the antenna assembly 200 from flipping under the drive of external forces (wind, etc.), further improving the stability of the antenna assembly 200 in the working position.

[0034] Alternatively, as shown in Figure 3(b), when the support portion 101 is an arc surface formed on the host 100, the pivot assembly 300 has a contact surface adapted to the arc surface. For example, if the arc surface is concave at the middle relative to both ends, then when the antenna assembly 200 is in the working position, the contact surface of the pivot assembly 300 will bulge downwards at the middle relative to both ends. This arrangement also ensures the stability of the antenna assembly 200.

[0035] Alternatively, as shown in Figure 3(c), when the support part 101 includes several block structures distributed at different positions on the top of the host 100, specifically, when the position of each block structure enables the antenna assembly 200 to rotate to a preset angle, different block structures contact different positions of the rotating shaft assembly 300, thereby jointly supporting the antenna assembly 200.

[0036] It should be noted that the rod or plate of the aforementioned pivot assembly 300 refers to a portion of the pivot assembly 300 that abuts against the support portion 101. The pivot assembly 300 also includes another portion for supporting the antenna assembly 200. The angle between this other portion of the pivot assembly 300 and the rod or plate portion can be adaptively adjusted so that when the rod or plate of the pivot assembly 300 abuts against the support portion 101, this other portion of the pivot assembly 300 can support the antenna assembly 200 above the host 100. Furthermore, in the various embodiments described above, magnets (which can protrude or be located internally) can also be provided on the pivot assembly 300 and the support portion 101 to further enhance the stability of the antenna assembly 200 in its working position.

[0037] In this embodiment of the invention, a support portion 101 is provided on the host 100, and the host 100 and the antenna assembly 200 are rotatably connected by a rotating shaft assembly 300. This allows the antenna assembly 200 to rotate relative to the host 100 within a certain angle range. When the antenna assembly 200 is rotated to a preset angle (which can also be understood as the angle of the working position), a portion of the rotating shaft assembly 300 will abut against the support portion 101 to stabilize the antenna assembly 200 at that preset angle (e.g., the working position). This arrangement ensures that the antenna assembly 200 remains stable during operation.

[0038] The specific structure of the electronic device provided in the embodiments of the present invention will now be described with reference to Figures 1-10. Figure 4 is an enlarged schematic diagram of the structure A in Figure 2. Figure 5 is a schematic diagram of the connection between the rotating shaft assembly and the rotary support assembly provided in some embodiments of the present invention. Figure 6 is a schematic diagram of the connection between the rotating shaft assembly and the housing provided in some embodiments of the present invention. Figure 7 is a schematic diagram of the antenna assembly in the working position provided in some embodiments of the present invention. Figure 8 is an enlarged schematic diagram of the structure B in Figure 7. Figure 9 is an exploded schematic diagram of the locking assembly and the first substrate provided in some embodiments of the present invention. Figure 10 is a schematic diagram of the unlocking and locking positions of the locking assembly provided in some embodiments of the present invention.

[0039] As shown in Figures 2 and 4 to 6, in some embodiments, the rotating shaft assembly 300 includes a connecting body 310, which includes a bent portion 311. The bent portion 311 is located between a first end and a second end of the connecting body 310. The first end of the connecting body 310 is rotatably connected to the host 100, and the second end of the connecting body 310 is fixedly connected to the antenna assembly 200. When the antenna assembly 200 rotates to a preset angle, the structure between the first end of the connecting body 310 and the bent portion 311 abuts against the support portion 101.

[0040] Specifically, the bend 311 on the connecting body 310 indicates that the first end and the second end of the connecting body 310 are not on the same horizontal line. In other words, the structure between the first end and the bend 311 of the connecting body 310 has a preset angle with the structure between the second end and the bend 311 of the connecting body 310. This preset angle can change the orientation of the antenna assembly 200 in the non-working position and the working position. Specifically, it can be set according to the working and non-working positions of the antenna assembly 200, as well as the setting position of the support part 101 of the host 100 or the shape of the support surface, to ensure that the orientation of the antenna assembly 200 meets the actual usage requirements. For example, in the working position, when the antenna assembly 200 is above the host 100, it extends vertically. At this time, the antenna assembly 200 is in a vertical posture. And at this time, the structure between the first end and the bend 311 of the connecting body 310 abuts against the support part 101. This configuration ensures that the antenna assembly 200 is stable in the working position and that the orientation of the antenna assembly 200 meets the actual requirements. Furthermore, if the actual requirements are different, only the preset angle needs to be changed, thereby expanding the application range of the electronic device.

[0041] To further understand this, setting a support part 101 on the host 100 can also be understood as forming a support surface on the top of the host 100. The setting of this support surface is equivalent to providing a stable support surface for the part between the first end of the main body 310 and the bending part 311, which can reduce the swaying of the antenna assembly 200 due to factors such as strong winds.

[0042] As shown in Figures 1, 2, 4 to 6, in some embodiments, the connecting body 310 further includes a first base 312 and a second base 313. The first base 312 is located between the bent portion 311 and the first end of the connecting body 310, and the second base 313 is located between the bent portion 311 and the second end of the connecting body 310. The extending direction of the first base 312 intersects the extending direction of the second base 313.

[0043] Specifically, the portion of the bent portion 311 that connects to the first end of the connecting body 310 is defined as the first base 312, and the portion of the bent portion 311 that connects to the second end of the connecting body 310 is defined as the second base 313. The extending direction of the first base 312 intersects the extending direction of the second base 313, that is, the first base 312 and the second base 313 are connected at a preset angle. The specific angle can be set according to the installation position or shape of the support portion 101, as well as the working position of the antenna assembly 200.

[0044] Taking the support portion 101 as an example of a support surface formed on the top of the host 100, when the antenna assembly 200 is in the working position, as shown in FIG. 7, the second base 313 is in a position perpendicular to the top of the host 100, while the first base 312 is in a position abutting against the support surface. If the support surface is an abutting plane formed on the top of the host 100, then the extending direction of the first base 312 is parallel to the top of the host 100, that is, the first base 312 is perpendicular to the second base 313. If the support surface is an abutting slope formed on the top of the host 100, and this slope slopes downward at a certain angle from the end away from the connection point between the first base 312 and the host 100, then the angle between the first base 312 and the second base 313 is an acute angle.

[0045] It should be noted that the angle between the first substrate 312 and the second substrate 313 is such that when the antenna assembly 200 is in the working position, the second substrate 313 is perpendicular to the top of the main unit 100, so that the antenna assembly 200 is above the main unit 100, and the surface of the first substrate 312 abuts against the bearing surface. This arrangement, through the plane-to-plane contact between the surface of the first substrate 312 and the bearing surface, facilitates the formation of a stable support structure, thereby ensuring stable support for the antenna assembly 200 in the direction perpendicular to the top of the main unit 100.

[0046] In some embodiments, the extending direction of the first substrate 312 is perpendicular to the extending direction of the second substrate 313. In this embodiment, when the rotation angle of the first substrate 312 relative to the support portion 101 of the host 100 is 0°, the second substrate 313 drives the antenna assembly 200 to adhere to the host 100. When the rotation angle of the first substrate 312 relative to the support portion 101 of the host 100 is 180°, the surface of the first substrate 312 abuts against the support portion 101, and the second substrate 313 drives the antenna assembly 200 away from the host 100.

[0047] It is understood that the first base 312 and the second base 313 are arranged vertically, that is, the connecting body 310 is arranged in an L-shape between the host 100 and the antenna assembly 200. To clearly describe the positional relationship between the first base 312 and the second base 313 and the host 100 when the antenna assembly 200 is flipped relative to the host 100, the first base 312 is defined to be able to flip 0°-180° relative to the support part 101 of the host 100. In addition, to clearly describe the positional relationship between the antenna assembly 200 and the host 100 during the flipping process of the first base 312, the antenna assembly 200 in this example has a flat plate structure. The flat plate antenna assembly 200 is disposed on one side of the host 100 and is basically adapted to the shape of the side wall of the host 100. When the first base 312 is rotated at 0°, as shown in Figure 1, the second base 313 is perpendicular to the top of the host 100. However, the end of the second base 313 away from the first base 312 (the end connected to the antenna assembly 200) extends towards the bottom of the host 100. The antenna assembly 200 is located on one side of the host 100 and is in contact with the host 100, that is, in a non-working position. The antenna assembly 200 is in a vertical position.

[0048] When the first base 312 flips from 0° to 180°, the end of the first base 312 near the second base 313 moves away from the main unit 100. The second base 313 drives the antenna assembly 200 to gradually move away from the side of the main unit 100 and rotate upward. When the flip angle of the first base 312 reaches 90°, the first base 312 is perpendicular to the top of the main unit 100, the second base 313 is parallel to the top of the main unit 100, and the antenna assembly 200 is in a horizontal position. As the first base 312 continues to flip until it reaches 180°, the surface of the first base 312 abuts against the support portion 101 on the top of the main unit 100, the second base 313 is perpendicular to the top of the main unit 100, and the antenna assembly 200 flips above the main unit 100 and is in a vertical position again, as shown in Figure 7. Since the surface of the first base 312 that abuts against the support portion 101 has a certain area, the stability of the plane-to-plane contact is ensured, thereby improving the stability of the antenna assembly 200 under wind force.

[0049] In other embodiments, the extending directions of the first substrate 312 and the second substrate 313 may not intersect at a perpendicular angle. For example, when the angle between the first substrate 312 and the second substrate 313 is set to an obtuse angle, and the flip angle of the first substrate 312 is less than 180°, the surface of the first substrate 312 can abut against the bearing surface at the top of the host 100, and the second substrate 313 can be perpendicular to the top of the host 100. The antenna assembly 200 flips above the host 100 and is in a vertical position. In actual operation, the actual flip angle of the first substrate 312 can be set according to the angle between the extending directions of the first substrate 312 and the second substrate 313, the shape of the bearing surface, and the working position of the antenna assembly 200, which will not be elaborated here.

[0050] As shown in Figures 4 to 6, in some embodiments, the host 100 includes a support body 120, which includes a first body 121 and a second body 122 arranged perpendicularly to each other. The first body 121 is disposed on the top of the host 100 to form a support portion 101, and the second body 122 is disposed on a first sidewall 102 intersecting with the top of the host 100.

[0051] It is understood that the support body 120 can form the aforementioned bearing part 101 on the one hand, and on the other hand, it can also be used to cooperate with the following walking component so that when the host 100 is in a horizontal position, the support body 120 and the walking component are located at the bottom of the host 100 in the horizontal position, thereby ensuring the levelness of the host 100 in the horizontal position.

[0052] In this example, the support body 120 includes a first body 121 and a second body 122 that are perpendicular to each other and fixedly connected. The first body 121 is located on top of the host 100, where "top" refers to the side of the host 100 facing the sky when the antenna assembly 200 is working. A support portion 101 is formed on the first body 121. It can also be understood that the support portion 101 is a part of the first body 121. For example, the support portion 101 is a support surface formed on the first body 121, that is, the surface of the first base 312 abuts against the surface of the first body 121. Alternatively, it can be understood that the first body 121 itself is the support portion 101.

[0053] As shown in Figures 2 and 7, in some embodiments, when the first base 312 is rotated at a 0° angle relative to the support portion 101 of the host 100, the second base 313 rotates to a second sidewall 103 opposite to the first sidewall 102 of the host 100 where the second body 122 is located, so that the antenna assembly 200 abuts against the second sidewall 103 of the host 100 (as shown in Figure 6), and the shape of the second sidewall 103 is substantially adapted to the shape of the antenna assembly 200. When the first base 312 is rotated at a 180° angle relative to the support portion 101 of the host 100, the second base 313 rotates to the top of the host 100, so that the antenna assembly 200 rotates above the host 100.

[0054] Specifically, to clearly describe the relative positional relationship between the connecting body 310 and the supporting body 120, we will still use the example of the first base 312 being able to rotate 0°-180° relative to the support portion 101 of the host 100. When the rotation angle of the first base 312 is 0°, the second base 313 is located on the side of the host 100 opposite to the second body 122. At this time, the antenna assembly 200 abuts against the second side wall 103 of the host 100 and is in a non-working position. When the rotation angle of the first base 312 is 180°, the surface of the first base 312 abuts against the surface of the first body 121, the second base 313 is perpendicular to the top of the host 100, and the antenna assembly 200 is located above the host 100.

[0055] In some embodiments, the top of the host 100 may be an uneven plane, such as having protrusions or tilted structures. If the first base 312 is directly placed on the top of the host 100, the rotation path of the first base 312 may be obstructed, meaning that the first base 312 may be blocked by certain structures during rotation. The above-described arrangement, which uses the first body 121 to support the first base 312, allows the first base 312 to form a height difference with the top of the host 100. This enables the first base 312 to rotate unimpeded to its surface fully contacting the first body 121 during a 180° rotation, and to rotate unimpeded to the antenna assembly 200 abutting against the second sidewall 103 of the host 100 during a 0° rotation. In some other embodiments, the top of the host 100 is a flat plane, or there are no obstacles on the top of the host 100 in the rotation path of the first base 312. In this case, the first base 312 can also be directly placed on the top of the host 100.

[0056] To better understand the flipping process of the antenna assembly 200 in the above embodiments, the electronic device is defined to include a non-working state (corresponding to the antenna assembly 200 being in a non-working position) and a working state (the antenna assembly 200 being in a working position).

[0057] The process of switching the electronic device from a non-working state to a working state is as follows: the first base 312 rotates at a 0° angle relative to the host 100. At this angle, the second base 313 drives the antenna assembly 200 to fit tightly against the second side wall 103 of the host 100, reducing space occupation and facilitating the carrying and movement of the electronic device. When it is necessary to start the electronic device into a working state, the antenna assembly 200 is rotated. Since the antenna assembly 200 is fixedly connected to the second base 313, the second base 313 begins to rotate, causing the first base 312 to rotate around its rotation connection point with the host 100. As the rotation continues, the first base 312 gradually approaches the support part 101 until the antenna assembly 200 rotates to a preset working angle. Generally, when the rotation angle of the first base 312 relative to the host 100 is close to 180°, the surface of the first base 312 is in full contact with the support surface of the support part 101, forming a large-area support. At this point, the second base 313 steadily supports the antenna assembly 200 away from the main unit 100, achieving its maximum extended state and placing the antenna in the optimal transmission and reception position to meet the signal shielding requirements of a large area. In operation, the first base 312 maintains a stable rotation angle of approximately 180° relative to the main unit 100, with its surface in close contact with the support portion 101, providing stable support for the antenna assembly 200. The second base 313 drives the antenna assembly 200 to fully extend, with either the transmitting or receiving end of the antenna assembly 200 facing the target interference area, enabling signal jamming operations.

[0058] The process of switching the electronic device from an active state to a non-active state is as follows: When the device is in the active state, the first base 312 is rotated 180° relative to the host 100, and the surface of the first base 312 abuts against the support portion 101, providing support for the antenna assembly 200. The second base 313 supports the antenna assembly 200 away from the host 100, and the antenna assembly 200 is in a signal transmitting or receiving position. When the operation ends and the electronic device is switched back to the non-active state, the antenna assembly 200 is rotated in the reverse direction. At this time, the second base 313 begins to drive the antenna assembly 200 to rotate back, and the first base 312 gradually disengages from the support portion 101. As the rotation continues, the antenna assembly 200 gradually approaches the second side wall 103 of the host 100 until the rotation angle of the first base 312 relative to the host 100 returns to 0°. In the non-working state, the first substrate 312 has a 0° rotation angle relative to the host 100, and the second substrate 313 drives the antenna assembly 200 to fit tightly against the second side wall 103 of the host 100 again, making the overall structure of the electronic device compact, easy to store, transport or store, and reducing the risk of damage to the antenna assembly 200 due to collisions or other factors during non-working periods.

[0059] In the above embodiments, the flipping process of the antenna assembly 200, the first substrate 312, and the second substrate 313 relative to the host 100 can be manually achieved by an operator. Alternatively, the process can be achieved through other means, such as by incorporating a control module and a drive component in the electronic device. When the electronic device needs to be started and enter the working state, the control module controls the rotating shaft assembly 300 to flip relative to the host 100 via the drive component, thereby rotating the antenna assembly 200 until it reaches a preset working angle, at which point the first substrate 312 abuts against the support portion 101. The process of switching the electronic device from the working state to the non-working state is similar and will not be described in detail here.

[0060] In one example, when the first substrate 312 is flipped at 180°, a pad (not shown) is provided on the side of the antenna assembly 200 facing the host 100.

[0061] As shown in FIG4, in some embodiments, the support portion 101 includes a support surface formed on the top of the host 100. The electronic device also includes a rotary support assembly 400 disposed on the support surface, the rotary support assembly 400 including a mounting base 410 rotatably connected to a first end of the connecting body 310.

[0062] Specifically, the support portion 101 can be a support surface directly formed on the top of the main unit 100 housing, or it can be a support surface formed on the first body 121. The mounting base 410 of the rotary support assembly 400 can be disposed on the top of the main unit 100 housing or on the first body 121. To improve the ease of assembly of the electronic device, the mounting base 410 and the connecting body 310 can be fixed to the rotary support assembly 400 and then installed together on the housing of the main unit 100. The mounting base 410 is mainly used to install the first end of the connecting body 310. A support bearing can be provided in the mounting base 410, and a rotating shaft can be provided in the support bearing. The end of the rotating shaft away from the support bearing passes through the first end of the connecting body 310, so as to achieve the purpose of rotating the first end of the connecting body 310 onto the main unit 100.

[0063] As shown in Figure 4, in some embodiments, the slewing support assembly 400 further includes a baffle 420, which is disposed on one side of the mounting base 410 and fixed to the bearing surface. The baffle 420 is configured such that when the connecting body 310 abuts against the bearing surface, the baffle 420 is in contact with the side wall of the connecting body 310.

[0064] Specifically, a baffle 420 is provided on one side of the mounting base 410 and fixed to the bearing surface. When the connecting body 310 (first base 312) abuts against the bearing surface, the baffle 420 limits the movement of the connecting body 310 (specifically, the first base 312), thereby reducing the swaying of the connecting body 310 due to external forces such as wind on the antenna assembly 200. When the connecting body 310 is located on the bearing surface, the baffle 420 can be provided on one side of the connecting body 310 or on both opposite sides of the connecting body 310; there is no limitation on this.

[0065] In addition to the above-mentioned method of setting a baffle 420 on one side of the mounting base 410 to limit the connection body 310, as shown in FIG4, in some embodiments, the bearing part 101 includes a bearing surface provided on the top of the host 100, the rotating shaft assembly 300 is provided with a positioning part 3101, and a limiting part 500 is provided on the bearing surface. When the rotating shaft assembly 300 abuts against the bearing surface, the limiting part 500 cooperates with the positioning part 3101 to limit the rotating shaft assembly 300 within a preset area of ​​the bearing surface.

[0066] Specifically, the positioning part 3101 can be disposed on the surface of the first substrate 312, while the limiting part 500 can be disposed on the surface of the first body 121. When the first substrate 312 abuts against the first body 121, the positioning part 3101 will be adapted and inserted into the limiting part 500, thereby limiting the rotating shaft assembly 300 within a predetermined area of ​​the bearing surface. This predetermined area can be understood as the area of ​​the first substrate 312 abutting against the first body 121. Through the adapted insertion of the positioning part 3101 and the limiting part 500, the stability of the antenna assembly 200 in the working state can be further enhanced.

[0067] In some embodiments, the positioning part 3101 is a positioning groove formed on the rotating shaft assembly 300, and the limiting part 500 is a limiting block fixed on the bearing surface.

[0068] Specifically, the positioning groove is a positioning groove formed on the surface of the first substrate 312, and the limiting part 500 is a limiting block provided on the bearing surface of the first body 121. The limiting block protrudes from the surface of the first body 121 and can be adapted to and inserted into the positioning groove. Of course, in addition to the above arrangement, in one example (not shown in the figure), the positioning part 3101 is a limiting block fixed on the rotating shaft assembly 300, and the limiting part 500 is a positioning groove formed on the bearing surface. By interchangeding the positions of the limiting block and the positioning groove, the first substrate 312 can also be stabilized on the first body 121, thereby further enhancing the stability of the antenna assembly 200 in the working state.

[0069] In addition, the positioning part 3101 and the limiting part 500 can also be configured with other mutually cooperating structures so that the first base 312 can stably abut against the first body 121. For example, the positioning part 3101 and the limiting part 500 can be mutually cooperating magnetic attraction structures, snap-fit ​​structures, etc., which are not limited here.

[0070] As shown in Figures 7 and 8, in some embodiments, the electronic device further includes a locking component 600, which is disposed on the host 100. The locking component 600 includes a driving part 610 and a moving part 620. The rotating shaft assembly 300 is provided with a snap-fit ​​part 3102 adapted to the moving part 620, so that when the rotating shaft assembly 300 abuts against the support part 101, the driving part 610 drives the moving part 620 to cooperate with the snap-fit ​​part 3102 to lock the rotating shaft assembly 300.

[0071] Specifically, the locking component 600 can be disposed on the aforementioned support body 120, specifically on the first body 121 of the support body 120. As shown in Figure 9, the specific implementation principle of the locking component 600 is as follows: the driving part 610 includes a support rod 6101 and a driving handle 6102. One end of the support rod 6101 is fixed to the first body 121, and the other end of the support rod 6101 is movably connected to the driving handle 6102. The moving part 620 is sleeved on the support rod 6101. In this embodiment, the moving part 620 can move along the support rod 6101 towards the first body 121 under the drive of the driving handle 6102 until it is adapted to engage with the locking part 3102 on the rotating shaft assembly 300, thereby locking the rotating shaft assembly 300. Furthermore, the movable part 620 can move along the support rod 6101 away from the first body 121 under the drive of the drive handle 6102 until it is unlocked from the locking part 3102 on the rotating shaft assembly 300, thereby unlocking the rotating shaft assembly 300.

[0072] To further understand the locking and unlocking of the pivot assembly 300 by the locking component 600, as shown in Figure 9, in one example, the drive handle 6102 and the end of the support rod 6101 are connected by a rotational connection, such as a cam-driven connection. An elastic element 630 is provided between the drive handle 6102 and the moving part 620, and the elastic element 630 abuts against the moving part 620. When the drive handle 6102 rotates, the elastic element 630 undergoes compression deformation under the drive of the drive handle 6102. The moving part 620, sleeved on the support rod 6101, moves towards the engaging part 3102 under the elastic force of the elastic element 630 until it engages with the engaging part 3102, thus locking the pivot assembly 300. When the drive handle 6102 rotates in the reverse direction, the elastic element 630 releases and returns to its original position, and the moving part 620 moves away from the locking part 3102, thereby unlocking the rotating shaft assembly 300. Taking the connection between the end of the drive handle 6102 and the support rod 6101 via a cam drive as an example, two implementation methods are provided. The first implementation method is shown in Figures 10(a) and 10(b), and the second implementation method is shown in Figures 10(c) and 10(d). The end of the drive handle 6102 connected to the support rod 6101 may include an unlocking surface 6103 and a locking surface 6104. The end of the drive handle 6102 can rotate relative to the axis a, and the distance between the unlocking surface 6103 and the axis a is less than the distance between the locking surface 6104 and the axis a. During rotation, the side of the drive handle 6102 opposite to the elastic element 630 will change. When the drive handle 6102 is rotated to the unlocked position, as shown in Figure 10(a) or Figure 10(c), the unlocking surface 6103 of the drive handle 6102 faces the elastic member 630, and the drive handle 6102 does not compress the elastic member 630 at this time. When the drive handle 6102 is rotated from the unlocked position to the locked position, as shown in Figure 10(b) or Figure 10(d), the side of the drive handle 6102 facing the elastic member 630 changes from the unlocking surface 6103 to the locking surface 6104, and the locking surface 6104 compresses the elastic member 630, causing it to undergo compressive deformation. The moving part 620 moves under the elastic force of the elastic member 630, realizing engagement with the locking part 3102. The process of the drive handle 6102 unlocking from the locked position to the unlocked position is the reverse, and will not be described in detail here. In addition, the drive handle 6102 and the support rod 6101 can also be connected in other ways to enable the drive handle 6102 to decompress and release the elastic element 630.

[0073] The structure and movement process of the movable part 620 are illustrated below. As shown in Figure 9, in some embodiments, the movable part 620 includes a movable body 6201, a snap-fit ​​member 6202, and a spring 6203. The movable body 6201 is sleeved on the support rod 6101 through a connecting hole. One end of the snap-fit ​​member 6202 is fixedly connected to the movable body 6201, and the other end of the snap-fit ​​member 6202 can engage with the snap-fit ​​part 3102. For example, the snap-fit ​​member 6202 can be understood as a protrusion, and the snap-fit ​​part 3102 can be understood as a slot. The protrusion can be fitted and inserted into the slot. One end of the spring 6203 is limited to the first body 121, and the other end is limited to the movable body 6201. When the rotating shaft assembly 300 abuts against the bearing surface, the movable body 6201 can move along the support rod 6101 towards the rotating shaft assembly 300 and the first body 121 under the rotation of the drive handle 6102. The spring 6203 undergoes compression deformation during the movement of the movable body 6201, allowing the locking member 6202 to engage with the locking portion 3102 on the rotating shaft assembly 300. Since the locking assembly 600 is fixedly mounted on the first body 121, the rotating shaft assembly 300 is fixed to the bearing surface by the engagement of the locking member 6202 and the locking portion 3102. This arrangement solves the problem of the antenna assembly 200 easily shaking during use in inclement weather.

[0074] As shown in Figure 8, in this example, when the latching member 6202 engages with the latching part 3102, the movable body 6201 can fit against the first body 121 under the compression limit of the spring 6203, further realizing the limiting function. Conversely, when the rotating shaft assembly 300 needs to move away from the bearing surface, the drive handle 6102 rotates in the opposite direction, providing space for the movable body 6201 to retract. The spring 6203 elastically recovers, and the movable body 6201 moves along the support rod 6101 away from the rotating shaft assembly 300 and the first body 121 under the elastic force of the spring 6203. The latching member 6202 moves away from the latching part 3102, realizing the release from the latching part 3102.

[0075] The locking assembly 600 provided in this example is not only simple in structure but also easy to operate, which facilitates the rapid fixation of the antenna assembly 200.

[0076] In other embodiments, the locking component 600 may also be of other structures. That is, as long as the locking component 600 has the function of locking the rotating shaft assembly 300 in the working state and unlocking the rotating shaft assembly 300 in the non-working state, it can achieve the rapid fixation of the antenna assembly 200. The specific form is not limited.

[0077] The operation of the antenna assembly 200 and the locking assembly 600 during the flipping process can be as follows: When the electronic device is in a non-operating state, the antenna assembly 200 is attached to the second side wall 103 of the host 100. At this time, the locking assembly 600 is in an unlocked state, and its moving part 620 does not engage with the locking part 3102 of the rotating shaft assembly 300, thus not hindering the rotation of the antenna assembly 200. When the antenna assembly 200 is rotated, gradually unfolding from the second side wall 103 of the host 100 and rotating towards the working position, the locking assembly 600 remains in an unlocked state, allowing the antenna assembly 200 to flip smoothly. The first base 312 and the second base 313 can move according to the designed rotation path until the antenna assembly 200 approaches the working position. When the antenna assembly 200 rotates to a preset working angle (for example, the flipping angle of the first base 312 relative to the support part 101 of the host 100 is close to 180°), the operator initiates the locking process by operating the drive part 610 of the locking assembly 600. For example, the movable part 620 extends and engages tightly with the locking part 3102 of the rotating shaft assembly 300 to forcefully lock the rotating shaft assembly 300. This prevents the antenna assembly 200 from rotating unexpectedly due to vibration, accidental contact, or other factors during the operation of the electronic device, ensuring that the antenna assembly 200 is stably in the working position and maintaining stable signal interference output.

[0078] When the antenna assembly 200 needs to be switched from the working position to the non-working position, the operator operates the drive part 610 of the locking component 600, causing the moving part 620 to retract and disengage from the locking part 3102 of the rotating shaft assembly 300, thus releasing the lock on the rotating shaft assembly 300. At this time, the antenna assembly 200 can rotate freely, preparing for storage. Rotating the antenna assembly 200 towards the second side wall 103 of the main unit 100, the locking component 600 remains unlocked during this process, without hindering the rotation of the antenna assembly 200, until the antenna assembly 200 is completely attached to the second side wall 103 of the main unit 100. After the antenna assembly 200 is attached to the second side wall 103 of the main unit 100, the electronic device returns to the non-working state, and the locking component 600 remains unlocked, awaiting the next use.

[0079] As shown in Figures 1 and 2, in one example, the electronic device includes two sets of rotating shaft assemblies 300. These two sets of rotating shaft assemblies 300 are spaced apart and connected to both ends of the same side of the antenna assembly 200. Specifically, providing a set of rotating shaft assemblies 300 at each opposite end of the antenna assembly 200 improves the stability of the antenna assembly 200 during rotation. Furthermore, since both sets of rotating shaft assemblies 300 abut against the bearing surface, the stability of the rotating shaft assemblies 300 against the host 100 is further improved, thereby enhancing the stability of the antenna assembly 200 positioned above the host 100.

[0080] This invention also provides a frequency jammer, as shown in Figure 1. The electronic devices in the above embodiments can all be specifically frequency jammers.

[0081] It is understood that the frequency jammer in this example may include all the structures such as the host 100, the rotating shaft assembly 300 and the antenna assembly 200 in the above embodiments. The antenna assembly 200 is mainly used to transmit jamming signals so that wireless communication devices cannot receive and transmit signals normally.

[0082] The frequency jammer can be used as a portable frequency jammer, such as a case-type frequency jammer. It typically includes a walking assembly, which in some examples may include casters mounted on one side of the bottom of the main unit 100 and a retractable pull rod mounted on the side wall of the main unit 100 on the same side as the casters. The installation of the casters and the retractable pull rod facilitates movement of the case-type frequency jammer by pulling the pull rod and dragging it on the ground. Of course, the frequency jammer provided in this example can also be a backpack-type frequency jammer, a suitcase-type frequency jammer, etc., without specific limitations.

[0083] This invention also provides a wireless signal jamming system, which includes an jammer control device and at least one frequency jammer as described in the above embodiments. The jammer control device is electrically or communicatively connected to the frequency jammer.

[0084] It is understood that in this wireless signal jamming system, the jammer control device is used to control the frequency jammer. Specifically, the jammer control device can control the frequency jammer to transmit jamming signals via various wireless or wired methods.

[0085] Alternatively, the wireless signal jamming system may include, for example, at least one frequency jammer as described in the above embodiments. One frequency jammer controls all the frequency jammers. The frequency jammers can communicate with each other via various wireless or wired methods. This embodiment of the invention does not limit this.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
