[0038] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] This invention provides an anti-tipping device to prevent equipment from tipping over, for example, it can be applied to a frequency jammer. It is understood that the anti-tipping device is not limited to the frequency jammer described above, but can also be used in devices in other fields to prevent equipment from tipping over.

[0040] Figures 1 to 4 The present invention illustrates a frequency jammer 1 in some embodiments. This frequency jammer 1 can be used to suppress the normal operation of wireless communication devices, such as blocking signals from mobile phones, pagers, or other wireless communication devices. Specific applications of the frequency jammer 1 include interfering with wirelessly controlled explosives, preventing them from detonating. Therefore, the frequency jammer 1 is suitable for maintaining confidentiality at important conference venues, ensuring security at locations frequented by important figures, and assisting bomb disposal personnel in transferring or handling suspected explosive devices.

[0041] like Figure 1 As shown, in some embodiments, the frequency jammer 1 may include a main body and an anti-tipping device 90 mounted on the outside of the main body. The main body, used for frequency jamming, may be cuboid in shape and have two opposing first sides 101 and two opposing second sides 102. The area of ​​the first sides 101 is smaller than the area of ​​the second sides 102. The anti-tipping device 90 can extend to support the ground during operation, preventing the main body from tipping over and improving the environmental adaptability of the frequency jammer 1.

[0042] Specifically, the anti-tipping device 90 can extend in the direction in which the main body is prone to tipping over. For example, the anti-tipping device 90 can be installed on the first side 101, and the installation direction of the anti-tipping device 90 can extend from one second side 102 (such as the front) to another second side 102 (such as the back).

[0043] The main body may include a main unit 10, an antenna module 20, a rotating connection assembly 30, and a signal transmission assembly 40. The antenna module 20 is movably mounted on the main unit 10; for example, the antenna module 20 can be flipped and connected to the main unit 10 via the rotating connection assembly 30. An anti-tipping device 90 is mounted on the third side 103 of the main unit. Wherein, for example... Figure 3 As shown, the host 10 has two opposing third sides 103 and two opposing fourth sides 104. The area of ​​the third side 103 is smaller than the area of ​​the fourth side 104, and the antenna module 20 is mounted on the fourth side 104. The third side 103 is, for example, on the same plane as the first side 101 described above, and the fourth side 104 is, for example, on the same plane as the second side 102 described above.

[0044] In some embodiments, the host unit 10 may have functions such as generating multi-band interference signals, realizing human-computer interaction, data processing, and power supply. In some embodiments, the antenna module 20 may be used to transmit the multi-band interference signals generated by the host unit 10 and to receive signals from a base station. In some embodiments, there may be two rotating connection components 30, each hinged to one side of the antenna module 20 onto the host unit 10, allowing the antenna module 20 to be flipped and connected to the host unit 10, enabling the antenna module 20 to switch between a closed state (retracted state) and an open state (operating state) relative to the host unit 10. It is understood that the rotating connection components 30 are not limited to two; one or more may be used. The signal transmission component 40 communicatively connects the antenna module 20 to the host unit 10, enabling signal transmission between the host unit 10 and the antenna module 20.

[0045] This frequency jammer 1 features a uniquely integrated antenna module 20, designed as a single unit integrated with the main unit 10 (meaning the antenna module 20 does not need to be removed for storage), making it highly portable. Furthermore, the antenna module 20 is designed as a hinged flip-top structure, allowing it to be rotated 180 degrees (e.g., ...) for use. Figure 4 (as shown) or 90 degrees (as shown) Figure 3 As shown in the image, it can be used without repeatedly disassembling and reassembling the antenna, making it very convenient to use and store. Furthermore, the frequency jammer 1 conceals the antenna modules in its appearance, resulting in a more harmonious and aesthetically pleasing overall design.

[0046] Understandably, the frequency jammer 1 is not limited to having only one antenna module 20. In some embodiments, it may also include two or more antenna modules 20, with the number of antennas in each antenna module 20 being reduced accordingly. Each antenna module 20 can be connected to the host 10 via its respective rotating connection assembly 30.

[0047] For example Figure 2As shown, in some embodiments, the host 10 may include a housing 11, a functional module assembly 12, and a power supply assembly 13. In some embodiments, the housing 11 may be generally cuboid in shape and may be made of high-strength, low-electromagnetic-wave-loss engineering plastic material. The functional module assembly 12 is disposed within the housing 11 and connected to the antenna module 20 via a signal transmission assembly 40, for generating multi-band interference signals. The power supply assembly 13 is disposed within the housing 11, located below the functional module assembly 12, and is detachably electrically connected to the functional module assembly 12 to provide power to the functional module assembly 12. It is understood that the housing 11 is not limited to a cuboid shape; in some embodiments, it may also be cubic, cylindrical, or other suitable shapes.

[0048] like Figures 5 to 9 As shown, in some embodiments, the antenna module 20 may be generally flat, and may include a housing 21 with an inner cavity, multiple first antennas disposed within the inner cavity, and a second antenna 23 disposed outside the housing 21. In some embodiments, the housing 21 may be rectangular, with one side rotatably connected to the host 10 via a rotating connection assembly 30. In some embodiments, an antenna connector 212 may be provided on the side of the housing 21 away from the rotating connection assembly 30 (top side) for detachably connecting the second antenna 23. The multiple first antennas may be connected to the functional module assembly 12 within the host 10 via a signal transmission assembly 40 for communication with the host 10. The antenna connector 212 is connected to one of the multiple first antennas (e.g., an antenna in the 20-200MHz band) to connect the second antenna 23 to the low-frequency antenna, providing gain to the low-frequency antenna.

[0049] In some embodiments, a pair of wire through holes 210 may be provided on the side (bottom side) of the housing 21 near the rotating connection assembly 30 for the signal lines of the signal transmission assembly 40 to pass through. In some embodiments, the second antenna 23 may be columnar and is detachably carried on one side of the housing 21 when not in operation.

[0050] like Figure 7 and Figure 10 As shown, in some embodiments, the anti-tipping device 90 may include a base 91, a support leg 92, and a limiting component 94. The base 91 can be installed on the outside of the main body, and the support leg 92 is movably installed in the base 91 along an axis C, with the axis C intersecting the ground. The intersection of the axis C with the ground allows the support leg 92 to move to the ground, thereby achieving the anti-tipping effect. For example... Figure 1As shown, the support leg 92 is installed at an angle on the bottom of the third side 103 of the main unit 10. When anti-tipping support is required, the support leg 92 extends diagonally downwards and beyond the placement position of the frequency jammer 1 until it touches the ground, thus reaching a position far from the main unit and improving the stability of the frequency jammer 1. It should be noted that the "axial direction" mentioned in the following embodiments is the same as the axial direction in this embodiment.

[0051] The limiting component 94 is fixed to the outrigger 92 and is used to lock the outrigger 92 relative to the base 91. Specifically, the limiting component 94 is used to operably lock the outrigger 92 to the base 91 and can operably release the lock between the outrigger 92 and the base 91. For example, when the outrigger 92 is extended to the ground, the limiting component 94 can be used to fix the outrigger 92, and when it is necessary to retract the outrigger 92, the limiting component 94 can release the lock between the outrigger 92 and the base 91, so that the outrigger 92 can be stored.

[0052] Therefore, in the anti-tipping device 90 provided in this embodiment, by providing an axially movable support leg 92 and a limiting component 94 for limiting the position of the support leg 92, it can provide fast and stable support for the main body, and ensure that the main body maintains a stable working state in different environments.

[0053] like Figure 7 As shown, in some embodiments, the anti-tipping device 90 may further include a leveling component 93 connected to the lower end of the support leg 92. The support leg 92 has an upper end and a lower end, with the lower end's distance from the ground being less than the upper end's distance from the ground. Therefore, when the support leg 92 is extended, the leveling component 93 contacts the ground. The leveling component 93 can rotate relative to the support leg 92, adjusting its posture to ensure better contact between the anti-tipping device 90 and the ground. Therefore, the leveling component 93 can adapt to uneven ground, improving the adaptability of the anti-tipping device 90.

[0054] In some embodiments, such as Figure 7 As shown in Figure 9, the base 91 may include a slide rail 910, and the support leg 92 is reciprocally mounted in the slide rail 910. Therefore, the support leg 92 can slide back and forth along the slide rail 910. In some embodiments, the slide rail 910 may be longitudinally elongated, and its extension direction may be parallel to the aforementioned axis, for example, extending downwards at an angle. The cross-section of the slide rail 910 may be C-shaped or other shapes. In this embodiment, the addition of the slide rail 910 makes it easier to extend and retract the support leg 92.

[0055] In some embodiments, such as Figure 8As shown, the slide rail 910 is provided with a travel groove 912, and the support leg 92 includes a limiting post 921 that can reciprocate within the travel groove 912. In some embodiments, the travel groove 912 can extend from the front to the back of the slide rail 910, or the travel groove 912 can be a groove provided on the slide rail 910. The travel groove 912 can be used to cooperate with the limiting post 921 to limit the maximum travel of the support leg 92.

[0056] In some embodiments, such as Figure 9 As shown, the limiting component 94 is installed inside the support leg 92. In some embodiments, the support leg 92 may be of a square tube shape to accommodate the limiting component 94. Understandably, the support leg 92 is not limited to a square tube shape; it may also be cylindrical, U-shaped, C-shaped, or other shapes, as long as it can accommodate the limiting component 94.

[0057] In some embodiments, such as Figures 9 to 11 As shown, the outrigger 92 includes an operating hole 920, and the limiting assembly 94 includes an operating member 942. The operating member 942 is exposed outside the operating hole 920, allowing the user to control the operating member 942 to extend or retract the outrigger 92. The operating hole 920 is, for example, located on the outer side of the outrigger 92 for easy user operation. Part of the user-operable structure of the operating member 942 may be exposed outside the operating hole 920. Alternatively, the entire operating member 942 may be exposed outside the operating hole 920.

[0058] See also Figures 9 to 13 In some embodiments, the support leg 92 is provided with a limiting hole 922, and the limiting assembly 94 is provided with a limiting member 945. The limiting member 945 can protrude from the limiting hole 922 and make frictional contact with the inner surface of the slide rail 910, or be accommodated within the limiting hole 922. Frictional contact means that when the limiting member 945 contacts the inner surface of the slide rail 910, there is friction between them, which can lock the support leg 92. If the operating member 942 causes the limiting member 945 to protrude from the limiting hole 922 and make contact with the inner surface of the slide rail 910, the support leg 92 can be locked; if the operating member 942 causes the limiting member 945 to enter the limiting hole 922, the support leg 92 is unlocked and can slide along the slide rail 910.

[0059] Furthermore, the outrigger 92 may also be provided with a pair of limiting holes 922, and the limiting assembly 94 may be provided with a pair of limiting members 945. One limiting hole 922 and the limiting member 945 are located on the first side, and the other limiting hole 922 and the limiting member 945 are located on the second side opposite to the first side. For example, as Figure 9 , Figure 10 As shown, one of the limiting holes 922 and the limiting member 945 is located on the upper side, and the other limiting hole 922 and the limiting member 945 are located on the lower side.

[0060] Furthermore, for each side (i.e., the first side and the second side mentioned above), the limiting member 945 can protrude from the limiting hole 922 and make frictional contact with the inner surface of the slide rail 910, or be accommodated within the limiting hole 922. Thus, if the operating member 942 is subjected to force, the limiting members 945 on both sides can protrude from the limiting hole 922 and make contact with the inner surface of the slide rail 910, thereby improving the stability of the locking leg 92.

[0061] It is understandable that the support leg 92 may only have one limiting hole 922, and the limiting component 94 may only have one limiting piece 945, as long as the limiting effect can be achieved.

[0062] In some embodiments, such as Figure 11 , Figure 12 As shown, the limiting assembly 94 may further include a limiting seat 941, an operating member 942, and an elastic member 943. The limiting seat 941 is fixed inside the support leg 92. The limiting seat 941 can serve as a support and is used to install other components of the limiting assembly 94.

[0063] The operating member 942 is reciprocally mounted on the limiting seat 941 in a direction parallel to the axial direction. An elastic member 943 is disposed between the operating member 942 and the limiting seat 941. The limiting assembly 94 also includes a mating member 944. The mating member 944 is located between the operating member 942 and the limiting member 945. Under the action of the operating member 942, the mating member 944 can cause the limiting member 945 to protrude from the limiting hole 922 and rub against the inner surface of the slide rail 910, or it can cause the limiting member 945 to be accommodated within the limiting hole 922.

[0064] The elastic element 943 can initially apply a spring force to the operating element 942, causing the operating element 942 to push the limiting element 945 out of the limiting hole 922 and into frictional contact with the inner surface of the slide rail 910 through the mating element 944. That is, the outrigger 92 is locked without manual operation. If the user applies a force to the operating element 942 in the opposite direction to the aforementioned spring force, the operating element 942 can then cause the limiting element 945 to enter the limiting hole 922 through the mating element 944, thereby releasing the locking of the outrigger 92.

[0065] Furthermore, if the limiting component 94 is provided with a pair of limiting members 945, the limiting component 94 may also be provided with a mating member 944 on the first side and the second side respectively. For each side, the mating member 944 is located between the operating member 942 and the limiting member 945. For example, the mating member 944 and the limiting member 945 are sequentially provided on the upper side of the operating member 942, and another mating member 944 and the limiting member 945 are sequentially provided on the lower side of the operating member 942.

[0066] In some embodiments, such as Figure 12As shown, the limiting seat 941 includes a first receiving groove 9410, a second receiving groove 9412 disposed at one end of the first receiving groove 9410 and whose groove depth direction intersects with the groove depth direction of the first receiving groove 9410, and a third receiving groove 9414 connected to the first receiving groove 9410. The specific structure of the first receiving groove 9410, the second receiving groove 9412, and the third receiving groove 9414 is not specifically limited (for example, it may have only one opening or multiple openings in different directions), as long as they can respectively accommodate the corresponding components.

[0067] The first receiving groove 9410 has its depth direction parallel to the axial direction. In other words, the first receiving groove 9410 has a channel whose extension direction is parallel to the axial direction. A resilient member 943, connected to the operating member 942 and with its length direction parallel to the axial direction, is installed in the third receiving groove 9414. The operating member 942 is movably disposed within the first receiving groove 9410 via the resilient member 943. Since the first receiving groove 9410 is connected to the third receiving groove 941, the operating member 942 can be connected to the resilient member 943, thereby allowing the operating member 943 to move axially.

[0068] The specific positional relationship between the first receiving slot 9410 and the third receiving slot 9414 is not limited in this embodiment. For example, the third receiving slot 9414 can be located at the side end of the first receiving slot 9410 (e.g., Figure 12 (as shown), or, the third containment slot 9414 is located at the bottom of the first containment slot 9410.

[0069] The inner wall of the second receiving groove 9412 is provided with a guide structure 9411, which allows the mating part 944 to move back and forth within the second receiving groove 9412 under the limitation of the guide structure 9411. In other words, the mating part 944 is slidably connected to the guide structure 9411, and the mating part 944 is located within the second receiving groove 9412. Furthermore, the depth direction of the second receiving groove 9412 can intersect perpendicularly with that of the first receiving groove 9410. In this case, the direction in which the mating part 944 can move is perpendicular to the direction in which the operating part 942 can move.

[0070] Furthermore, in some embodiments, such as Figure 12 , Figure 13 As shown, the mating component 944 includes a receiving groove 9440 for accommodating the limiting component 945 and a guide mating structure 9443 for mating with the guide structure 9411. In some embodiments, the guide structure 9411 may be a guide protrusion, and correspondingly, the guide mating structure 9443 may be a guide groove that mates with the guide protrusion. It can be understood that in other embodiments, the guide structure 9411 may be a guide groove and the guide mating structure 9443 may be a guide protrusion.

[0071] In this embodiment, by setting the above-mentioned receiving slots, the various components of the limiting component 94 are compactly installed together and can effectively realize the limiting function.

[0072] In some embodiments, such as Figure 12 As shown in Figure 13, the operating member 942 includes an operating part 9421, a driving part 9422 connected to the operating part 9421, and a connecting part 9423 for connecting to the elastic member 943. The operating part 9421 is used by the user to push the operating member 942 to move. The operating part 9421 may be exposed in the operating hole 920. The driving part 9422 cooperates with the mating member 944 to drive the mating member 944 to move. The elastic member 943 is pre-pressed and disposed in the third receiving groove 9414. The connection method between the connecting part 9423 and the elastic member 943 includes mutual abutment.

[0073] Understandably, the connection between the elastic element 943 and the connecting portion 9423 includes direct or indirect connection or abutment. Furthermore, the elastic element 943 is pre-compressed, thus providing a spring force to the operating element 942 in the initial state (or when the operating element 942 is not manually driven). Under this spring force, the driving portion 9422 of the operating element 942 drives the mating part 944 to move, causing the limiting element 945 to protrude from the limiting hole 922 to lock the support leg 92. In some embodiments, the elastic element 943 may be a columnar spring.

[0074] In some embodiments, such as Figure 12 As shown, the contact surface between the drive unit 9422 and the mating member 944 is an inclined surface, denoted as the first inclined surface 9422a. The first inclined surface 9422a has a first end and a second end, with the first end connected to the operating unit 9421. The contact surface between the mating member 944 and the drive unit 9422 is an inclined surface with the same inclination direction as the first inclined surface 9422a. In other words, the drive unit 9422 and the mating member 944 are in contact via an inclined surface, thereby converting the axial force of the drive unit 9422 into a force perpendicular to the axial direction, allowing the mating member 944 to move perpendicularly relative to the axial direction. If the anti-tipping device 90 is placed horizontally, the height of the first end is higher than the height of the second end. For example, the first inclined surface 9422a is inclined downwards.

[0075] Furthermore, such as Figure 12 , 13As shown, if the first side and the second side each have a mating member 944 and a limiting member 945, then the surfaces of the driving part 9422 that contact the mating members 944 on the first side and the second side respectively are a first inclined surface 9422a and a second inclined surface 9422b. The first inclined surface 9422a has a first end and a second end opposite to each other, and the first end is connected to the operating part 9421; the second inclined surface 9422b has a third end and a fourth end opposite to each other, and the third end is connected to the operating part 9421. The distance between the first end and the third end is greater than the distance between the second end and the fourth end. In some embodiments, the inclination direction of the surface of the mating member 944 on the first side that contacts the first inclined surface 9422a is parallel to the inclination direction of the first inclined surface 9422a; the inclination direction of the surface of the mating member 944 on the second side that contacts the second inclined surface 9422b is parallel to the inclination direction of the second inclined surface 9422b. For example, in some embodiments, the drive unit 9422 may be V-shaped when viewed from the side, and the first inclined surface 9422a may be inclined downwards, and correspondingly, the bottom of the mating member 944 located on the upper side is also inclined downwards. The second inclined surface 9422b may be inclined upwards, and correspondingly, the top of the mating member 944 located on the lower side is also inclined upwards.

[0076] It is understandable that if only one set of mating parts 944 and limiting parts 945 are needed, the drive unit 9422 may also have only one inclined surface, such as the first inclined surface 9422a mentioned above.

[0077] In some embodiments, each mating member 944 may be wedge-shaped, and it further includes an inclined surface 9441 that mates with the drive portion 9422 of the operating member 942, and a connecting surface 9442 for connection with the limiting member 945. The engagement of the inclined surface 9441 of the mating member 944 with the drive portion 9422 converts the displacement of the operating member 942 along the axial direction C into a displacement of the mating member 944 along a direction D perpendicular to the axial direction C (e.g., ...). Figure 10 (As shown). Each limiting member 945 can be fixed to the connecting surface 9442 of the mating member 944 by a locking fastener and is used to provide friction with the slide rail 910.

[0078] During operation, the anti-tipping device 90 utilizes an elastic element 943 to apply an elastic force towards the mating element 944 to the operating element 942. The driving part 9422 of the operating element 942, in conjunction with the mating element 944, provides a force perpendicular to the axial direction to the mating element 944. The mating element 944 then drives the limiting element 945 to press tightly against the inner surface of the slide rail 910 of the base 91. Through the friction between these two elements, the base 91 and the support leg 92 are relatively fixed. When the support leg 92 needs to extend or retract, the user can apply a reaction force to the operating element 942 to overcome the resistance of the elastic element 943, driving the operating element 942 to move in the opposite direction. After losing the support force of the driving part 9422 of the operating element 942, the mating element 944 and the limiting element 945 become loose, and the friction between the limiting element 945 and the inner surface of the slide rail 910 significantly decreases, allowing the support leg 92 to move freely.

[0079] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0080] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
