Description

Technical Field

[0001] This invention relates to the field of vehicle communication, and more specifically to a vehicle-mounted anti-vibration communication jamming device. Background Technology

[0002] Vehicle-mounted communication is a communication system that integrates high mobility, communication jamming, anti-jamming, and high environmental adaptability. In complex, changeable, and harsh operating environments, vehicle-mounted communication countermeasures systems not only need good communication countermeasures capabilities but also need to adapt to changing and harsh environments. When vehicles move at high speeds, they generate vibrations, which affect the service life of the communication device. At the same time, because the housings used in existing vehicle-mounted communication systems are usually fixed with nuts, these nuts are prone to corrosion due to humid air, making them difficult to disassemble or easy to loosen under vibration. Summary of the Invention

[0003] This invention provides a vehicle-mounted anti-vibration communication interference device to solve the above-mentioned problems.

[0004] The present invention provides a vehicle-mounted anti-vibration communication jamming device, which adopts the following technical solution: a vehicle-mounted anti-vibration communication jamming device, comprising a base, a lower housing, an upper housing, a fixing component, and a locking component;

[0005] The lower housing abuts against the base; multiple through holes are provided on the side wall of the lower housing;

[0006] The upper housing is located above the base; a limiting ring with an L-shaped cross section is fixed on the inner wall of the upper housing; the outer wall of the limiting ring and the inner wall of the upper housing form an upward-opening annular groove; the lower end face of the upper housing and the upper end face of the lower housing form a locking gap;

[0007] The fixing component includes a center block and a J-shaped hook; the center block is located inside the lower housing; the center block is limited in the through hole by a connecting rod; the J-shaped hook is located at the upper end of the center block; the J-shaped hook includes elastic rods arranged at the top and bottom; the lower end of the elastic rod is fixed to the center block, and the upper end is fixed to an inverted L-shaped bent rod on the side near the lower housing; the bent rod and the elastic rod form a hook fixing gap with the opening facing downward.

[0008] The locking assembly is located within the locking gap and is used to provide an upward thrust to the upper housing when the bent rod and the limit ring are engaged, thereby fixing the upper and lower housings. This eliminates the need for nuts and prevents humid air from affecting the installation and disassembly of the housings.

[0009] Furthermore, the locking assembly includes a lower pressure frame; the lower pressure frame includes two symmetrically arranged U-shaped rods; the two U-shaped rods form a rectangular frame; a tension spring connects the two U-shaped rods. When the bent rod and the limiting ring engage, the tension spring is first stretched so that the lower pressure frame fits outside the locking gap. Then, the tension spring is released, and the released force pulls the lower pressure frame into the locking gap, providing an upward pushing force to the upper housing.

[0010] Furthermore, the locking assembly also includes a convex ring; the convex ring is fixed to the inner wall of the lower housing and is located at the upper end of the lower housing; the outer wall of the convex ring and the inner wall of the upper housing are in sliding engagement. This is used to restrict the movement of the lower pressure frame and improve stability when the lower pressure frame is engaged in the locking gap.

[0011] Furthermore, the base is equipped with a rubber pad to support the vehicle communication components; the through hole is a longitudinal hole, with its upper end flush with the lower end of the convex ring; the center block is slidably installed in the through hole via a connecting rod.

[0012] A compression spring is fixedly connected between the connecting rod and the through hole; a fixing post is fixed to the lower end of the center block;

[0013] A pressing head is provided on the outer side of the lower housing; the initial height of the upper end of the pressing head is higher than the height of the upper end face of the lower housing; the pressing head and the central block are fixedly connected by a connecting rod. In use, the pressing frame is pressed down. When the pressing frame corresponds to the locking gap between the lower housing and the upper housing, the tension spring releases the force and pulls the pressing frame into the locking gap, causing the pressing frame to squeeze the pressing head and the compression spring, which drives the central block to move the fixing column down to press against the vehicle communication element. The vehicle communication element and the rubber pad are pressed together, avoiding individual installation and saving installation time.

[0014] Furthermore, the base is provided with a positioning protrusion ring; the positioning protrusion ring is located on the outside of the rubber pad; the outer wall of the positioning protrusion ring is adapted to the inner wall of the lower housing.

[0015] Furthermore, a limiting groove is provided on the lower end face of the upper housing near the center of the upper housing; the limiting groove and the convex ring are in sliding fit.

[0016] Furthermore, multiple fixing components are provided along the lower housing.

[0017] The beneficial effects of this invention are as follows: when the upper housing moves the limiting ring downward, the limiting ring drives the elastic rod to deform inward so that the limiting ring passes the J-hook, and the J-hook resets so that the hook-fixed gap is above the bent rod, the locking component provides an upward pushing force to the upper housing, so that the bent rod and the limiting ring engage, thereby fixing the upper housing and the lower housing. This avoids the use of nuts and prevents humid air from affecting the installation and disassembly of the housing.

[0018] Furthermore, when the lower pressure frame is pressed down, and the locking gap between the lower pressure frame and the lower housing and the upper housing corresponds, the tension spring releases the force to pull the lower pressure frame into the locking gap, causing the lower pressure frame to squeeze the lower pressure head and squeeze the compression spring, driving the center block to move the fixing column down to press against the vehicle communication element. The vehicle communication element is pressed against the rubber pad, avoiding individual installation while achieving shock resistance and saving installation time. Attached Figure Description

[0032] An embodiment of the vehicle-mounted anti-vibration communication jamming device of the present invention, such as... Figures 1 to 7 As shown: A vehicle-mounted anti-vibration communication jamming device includes a base 200, a lower housing 300, an upper housing 400, a fixing component 500, and a locking component; the base 200 is provided with a rubber pad 210 for supporting the vehicle-mounted communication component 100;

[0033] The lower housing 300 abuts against the base 200; the lower housing 300 has multiple through holes 310 on its side wall; the through holes 310 are longitudinal holes, and their upper ends are flush with the lower ends of the protruding ring 630;

[0034] The upper housing 400 is located above the base 200; a limiting ring 410 with an L-shaped cross section is fixed on the inner wall of the upper housing 400; the outer wall of the limiting ring 410 and the inner wall of the upper housing 400 form an annular groove with the opening facing upward; the lower end face of the upper housing 400 and the upper end face of the lower housing 300 form a locking gap 640.

[0035] The fixing component 500 includes a center block 510 and a J-shaped hook 540; the center block 510 is located inside the lower housing 300; the center block 510 is slidably installed in the through hole 310 via a connecting rod 520; a compression spring 530 is fixedly connected between the connecting rod 520 and the through hole 310; a fixing post 550 is fixedly fixed at the lower end of the center block 510; a lower pressing head 560 is provided on the outer side of the lower housing 300; the initial height of the upper end of the lower pressing head 560 is higher than the height of the upper end surface of the lower housing 300; the lower pressing head 560 and the connecting rod 520 of the center block 510 are fixedly connected. In use, the lowering frame 610 is pressed down. When the lowering frame 610 corresponds to the locking gap 640 between the lower housing 300 and the upper housing 400, the tension spring 620 releases force to pull the lowering frame 610 into the locking gap, causing the lowering frame 610 to press the lowering head 560 and the compression spring 530, driving the center block 510 to move the fixing column 550 down to press against the vehicle communication element 100. The vehicle communication element 100 is pressed against the rubber pad 210, avoiding individual installation and saving installation time.

[0036] J-shaped hook 540 is provided on the upper end of center block 510; J-shaped hook 540 includes elastic rods arranged vertically; the lower end of the elastic rod is fixed on center block 510, and the upper end is fixed with an inverted L-shaped bent rod on the side near the lower housing 300; the bent rod and the elastic rod form a hook fixing gap with the opening facing downward.

[0037] The locking assembly is located within the locking gap 640 and provides an upward pushing force to the upper housing 400 when the bent rod and the limiting ring 410 engage, thus securing the upper housing 400 and the lower housing 300. This eliminates the need for nuts and prevents humid air from affecting the installation and disassembly of the housings. The locking assembly includes a lower pressure frame 610 and a convex ring 630. The lower pressure frame 610 includes two symmetrically arranged U-shaped rods that form a rectangular frame. A tension spring 620 connects the two U-shaped rods. When the bent rod and the limiting ring 410 engage, the tension spring 620 is first stretched so that the lower pressure frame 610 fits outside the locking gap 640. Then, the tension spring 620 is released, and the released force pulls the lower pressure frame 610 into the locking gap, providing an upward pushing force to the upper housing 400. The convex ring 630 is fixed to the inner wall of the lower housing 300 and is located at the upper end of the lower housing 300; the outer wall of the convex ring 630 and the inner wall of the upper housing 400 are in sliding fit. It is used to restrict the movement of the lower pressure frame 610 and improve stability when the lower pressure frame 610 is engaged in the hook-fixed gap.

[0038] In this embodiment, a positioning protrusion ring is provided on the base 200; the positioning protrusion ring is located on the outside of the rubber pad 210; the outer wall of the positioning protrusion ring is adapted to the inner wall of the lower housing 300. A limiting groove is provided on the lower end face of the upper housing 400 near the center of the upper housing 400; the limiting groove and the protrusion ring 630 are slidably engaged. Multiple fixing components 500 are provided along the lower housing 300 to improve the tightness of the connection between the upper housing 400 and the lower housing 300.

[0039] Based on the above embodiments, the working principle and process of the present invention are as follows: In use, when the upper housing 400 drives the limiting ring 410 to move downward, the limiting ring 410 drives the elastic rod to deform inward, causing the limiting ring 410 to pass over the J-hook 540. When the J-hook 540 resets and the hook-fixing gap is above the bent rod, the tension spring 620 is first stretched so that the lower pressure frame 610 is sleeved on the outside of the locking gap 640. Then, the tension spring 620 is released, and the tension spring 620 releases its force to pull the lower pressure frame 610 into the hook-fixing gap, providing an upward pushing force for the upper housing 400, so that the bent rod and the limiting ring 410 are tightly engaged, thereby fixing the upper housing 400 and the lower housing 300. This avoids the use of nuts and prevents humid air from affecting the installation and disassembly of the housing.

[0040] Meanwhile, when the lower pressure frame 610 corresponds to the locking gap 640 between the lower housing 300 and the upper housing 400, the tension spring 620 releases force to pull the lower pressure frame 610 into the locking gap, causing the lower pressure frame 610 to press the lower pressure head 560 and the compression spring 530, driving the center block 510 to move the fixing column 550 down to press against the vehicle communication element 100. The vehicle communication element 100 is pressed against the rubber pad 210, achieving shock resistance while avoiding individual installation and saving installation time.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
