Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted emergency communication antennas, in particular to a high-performance vehicle-mounted emergency communication antenna. Background Art

[0002] Vehicle-mounted emergency communication antennas are a type of communication equipment designed specifically for mobile platforms that can achieve stable connections with satellites or other communication nodes while the vehicle is in motion. These antennas are typically highly maneuverable and rapidly deployable, enabling them to quickly establish effective communication links in emergency situations, providing support for rescue operations, on-site command, and information collection. They feature high performance features such as automatic data acquisition and display, multi-satellite parameter storage, dual-mode positioning, automatic satellite alignment, memory and self-test capabilities, and diverse interfaces.

[0003] For example, Chinese patent CN 219303936 U discloses a vehicle-mounted communication antenna, which includes a square box with a waterproof roof installed on the top of the square box, wedges fixedly installed on both sides of the top of the square box, a support plate movably installed on the upper part of the interior of the square box, and an antenna pole installed in the middle of the top of the support plate.

[0004] The above-mentioned vehicle-mounted communication antenna still has certain shortcomings. It is equipped with a buffer structure. When the vehicle shakes during operation, the movable rod expands to both sides, pulling spring 1 to produce a buffering effect, thereby alleviating the shaking of the antenna pole installed in the middle of the support plate. However, only using the spring for buffering without setting a damper can easily cause the antenna pole to shake continuously, resulting in a decrease in the buffering effect. Therefore, this application proposes a high-performance vehicle-mounted emergency communication antenna to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a high-performance vehicle-mounted emergency communication antenna with the advantage of good buffering effect. It solves the problem that the antenna pole is easily shaken continuously and the buffering effect is reduced when only buffering is performed by springs without setting a damper.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a high-performance vehicle-mounted emergency communication antenna, comprising a base, a first shell being fixed to the upper surface of the base by bolts, a second shell being slidably connected to the outer teeth of the first shell, a vehicle-mounted emergency communication antenna body being fixed to the upper surface and at the center of the second shell, a disassembly mechanism being provided inside the first shell, and a buffer mechanism being provided inside the first shell;

[0007] The disassembly mechanism includes two connecting blocks respectively fixed on the left and right sides of the second shell, the interiors of the two connecting blocks are threadedly connected with screws, the outer sides of the two screws are fixed with baffles, the inner bottom wall of the first shell is movably fitted with two connecting plates, the lower surfaces of the two connecting plates are provided with grooves, the inner top walls of the two grooves are rotatably provided with connecting columns through bearings, the bottom ends of the two connecting columns are fixedly connected with studs, and the bottom ends of the two studs are fixed with mounting columns;

[0008] The buffer mechanism includes two cylinders fixed on the upper surfaces of two connecting plates, two springs are fixed on the inner bottom walls of the two cylinders, two dampers are fixed on the inner bottom walls of the two cylinders, and two protrusions are fixed on the top tubes of the dampers on the left and right sides respectively.

[0009] Furthermore, the second shell is shaped like a rectangular body with a hollow interior and missing front, rear and bottom parts. The left and right side walls of the inner cavity of the second shell are provided with sliding grooves extending to the bottom thereof, and the left and right sides of the first shell are fixed with sliders slidably connected to the sliding grooves.

[0010] Furthermore, the two baffles are movably fitted on the bottom of the second shell, and handles are fixed on the top ends of the two screws.

[0011] Furthermore, the base and the lower surface of the first shell are each provided with two vertically penetrating communication grooves, and the two studs are respectively threadedly connected to the inside of the two communication grooves.

[0012] Furthermore, the bottoms of the two mounting posts are each provided with a transverse groove, and the upper surface of the base is provided with four mounting grooves.

[0013] Furthermore, the two protrusions are fixed to the inner top wall of the second shell, and the tops of the two cylinders are respectively provided with two empty grooves located outside the two protrusions.

[0014] Furthermore, the springs on the left and right sides are respectively sleeved on the outer sides of the dampers on the left and right sides, and the springs on the left and right sides are respectively fixed on the bottom ends of the two protrusions.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] 1. This high-performance vehicle-mounted emergency communication antenna can buffer the impact force when the vehicle moves through the compression of the left and right springs and the left and right dampers, thereby improving the stability of the vehicle-mounted emergency communication antenna and having the advantage of good buffering effect.

[0017] 2. This high-performance vehicle-mounted emergency communication antenna rotates the two mounting posts and the two handles so that the two baffles no longer fit the bottom of the second shell. At this time, the first shell and the second shell can be separated, making it easier to maintain their internal components. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-2 In this embodiment, a high-performance vehicle-mounted emergency communication antenna includes a base 1, a first shell 3 is fixed to the upper surface of the base 1 by bolts, the outer teeth of the first shell 3 are slidably connected to the second shell 5, and a vehicle-mounted emergency communication antenna body 6 is fixed to the upper surface of the second shell 5 and at its center. A disassembly mechanism 2 is provided inside the first shell 3, and a buffer mechanism 4 is provided inside the first shell 3.

[0025] The second shell 5 is in the shape of a rectangular body with a hollow interior and missing front, rear and bottom sides. The left and right side walls of the inner cavity of the second shell 5 are provided with slide grooves extending to its bottom. Sliders slidably connected to the slide grooves are fixed on the left and right sides of the first shell 3. Four mounting grooves are provided on the upper surface of the base 1. The base 1 is fixed to the external vehicle body through the four mounting grooves. It has high performance characteristics by utilizing its own functions such as automatic collection and display, multi-star parameter storage, dual-mode positioning, automatic satellite alignment, memory and self-test functions and interface diversity.

[0026] See also Figure 3 In order to facilitate the maintenance of its internal components, the disassembly mechanism 2 in this embodiment includes two connecting blocks 201 fixed on the left and right sides of the second shell 5 respectively. The interior of the two connecting blocks 201 is threadedly connected with a screw 202, and the outer sides of the two screws 202 are fixed with a baffle 203. The inner bottom wall of the first shell 3 is movably fitted with two connecting plates 204. The lower surfaces of the two connecting plates 204 are provided with grooves 205. The inner top walls of the two grooves 205 are both equipped with connecting columns that rotate through bearings. The bottom ends of the two connecting columns are fixedly connected with studs 206, and the bottom ends of the two studs 206 are fixed with mounting columns 207.

[0027] In this example, the two baffles 203 are movably fitted to the bottom of the second shell 5, and handles are fixed to the tops of the two screws 202. The two mounting posts 207 are rotated to make the studs 206 gradually disengage from the two connecting grooves. The base 1 and the lower surface of the first shell 3 are each provided with two vertically penetrating connecting grooves. The two studs 206 are respectively threadedly connected to the inside of the two connecting grooves. The bottoms of the two mounting posts 207 are each provided with horizontal grooves. When the two studs 206 gradually disengage from the two connecting grooves, the two handles are then rotated to make the two screws 202 drive the two baffles 203 to start rotating, so that the two baffles 203 are no longer fitted to the bottom of the second shell 5. At this time, the first shell 3 and the second shell 5 can be separated, which is convenient for maintenance of their internal components.

[0028] It should be noted that, through the compression of the left and right springs 402 and the left and right dampers 403, the impact force when the vehicle moves can be buffered, the stability of the vehicle-mounted emergency communication antenna can be improved, and it has the advantage of a good buffering effect.

[0029] See also Figure 4 In order to improve the buffering effect, the buffering mechanism 4 in this embodiment includes two cylinders 401 fixed on the upper surfaces of the two connecting plates 204, two springs 402 are fixed on the inner bottom walls of the two cylinders 401, two dampers 403 are fixed on the inner bottom walls of the two cylinders 401, and two protrusions 404 are fixed on the top tubes of the dampers 403 on the left and right sides respectively.

[0030] In this example, the two protrusions 404 are fixed on the inner top wall of the second shell 5, and the tops of the two cylinders 401 are respectively provided with two empty grooves located on the outside of the two protrusions 404. The left and right springs 402 are respectively mounted on the outside of the left and right dampers 403, and the left and right springs 402 are respectively fixed on the bottom ends of the two protrusions 404. Through the compression of the left and right springs 402 and the left and right dampers 403, the impact force when the vehicle body moves can be buffered, which can improve the stability of the vehicle-mounted emergency communication antenna.

[0031] It should be noted that by rotating the two mounting posts 207 and the two handles, the two baffles 203 are no longer in contact with the bottom of the second shell 5 , and the first shell 3 and the second shell 5 can be separated, making it easier to maintain their internal components.

[0032] It can be understood that the electrical components appearing in the text are all electrically connected to the main controller and the power supply and the electrical components appearing in the text are all conventionally known devices. This application will not go into too much detail. The main controller can be a conventionally known device that controls a computer, etc. The control circuit of the main controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present utility model is mainly used to protect mechanical devices. Therefore, the present utility model will no longer explain in detail the control method and circuit connection. At the same time, the parts not described in detail in the present utility model are all common technologies of technicians in this field.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] The working principle of the above embodiment is:

[0035] (1) When the vehicle-mounted emergency communication antenna is used, the base 1 is fixed to the vehicle body, and its own functions such as automatic acquisition and display, multi-star parameter storage, dual-mode positioning, automatic satellite alignment, memory and self-test functions and interface diversity are utilized to make it have high performance characteristics. At the same time, through the compression of the left and right springs 402 and the left and right dampers 403, the impact force when the vehicle body moves can be buffered, which can improve the stability of the vehicle-mounted emergency communication antenna.

[0036] (2) When the vehicle-mounted emergency communication antenna needs to be maintained, the two mounting posts 207 are rotated so that the two studs 206 gradually disengage from the two connecting grooves. The two handles are then rotated so that the two screws 202 respectively drive the two baffles 203 to start rotating so that the two baffles 203 no longer fit the bottom of the second shell 5. At this time, the first shell 3 and the second shell 5 can be separated, making it easier to maintain their internal components.
