Description

Technical Field

[0001] This utility model relates to the field of mobile live streaming vehicle technology, specifically a side-hidden antenna structure and a live streaming vehicle. Background Technology

[0002] Mobile live streaming vehicles are needed for high-definition live broadcasts that require real-time switching during stage performances and music festivals; for special reports on education and healthcare in remote mountainous and rural areas, transmitting interview materials in real time; and for research and inspections of livelihood projects. These applications enable efficient and flexible on-site production and dissemination.

[0003] Although concealed antenna technology (such as PCB-mounted antennas and SMT-mounted antennas) can be used in the field of vehicle communication, in mountainous areas, tunnels and other areas where terrain obstruction or base station distance is long, the gain and directivity of concealed antennas are difficult to meet the low latency requirements of real-time high-definition live streaming. The live streaming vehicle still needs an external antenna. Moreover, the live streaming vehicle needs to process multiple frequency band signals such as satellite communication and 5G backhaul at the same time. The wide bandwidth characteristics of external antennas are better than most concealed solutions.

[0004] External antennas are usually installed on the top of mobile live streaming vehicles, which increases the height of the vehicle and prevents it from passing through some height-restricted areas. In addition, the antennas located on the top of the mobile live streaming vehicle will compete for space with equipment such as PTZ cameras and lifting lights on the roof of the vehicle, affecting the deployment of cameras or lighting equipment on the roof of the mobile live streaming vehicle. Utility Model Content

At the bottom of the antenna body is a support plate that can move outward from inside the housing. Inside the housing is a horizontal drive mechanism for driving the support plate to move outward from inside the housing. A telescopic cylinder is fixedly connected to the top of the support plate, and a cylindrical movable sleeve is fixedly connected to the top of the telescopic cylinder. The cylindrical movable sleeve is fitted onto the outer surface of the telescopic cylinder, and a connector is fixedly connected between the cylindrical movable sleeve and the antenna body. The telescopic cylinder is used to drive the cylindrical movable sleeve to move up and down, and the cylindrical movable sleeve drives the antenna body to move up and down through the connector.

[0007] Preferably, the end of the sliding sleeve facing the outside of the receiving chamber is fixedly connected to the closing baffle, which is used to drive the closing baffle to move together, opening or closing the receiving chamber.

[0008] Preferably, the horizontal drive mechanism includes a first drive motor and a first threaded sleeve, the first threaded sleeve being fixed to one end of the support plate and the first drive motor being fixed inside the receiving compartment.

[0009] Preferably, the output end of the first drive motor is fixedly connected to a first drive screw, and the first drive screw is threadedly connected to a first threaded sleeve for driving the first threaded sleeve and the support plate to move horizontally.

[0010] Preferably, the horizontal drive mechanism includes a second drive motor and a second threaded sleeve. A motor bracket is fixedly connected to one side of the inner wall of the accommodating chamber. The second drive motor is fixedly mounted on the motor bracket. The second threaded sleeve is fixed to one end of the support plate. A second drive screw and a linkage gear are rotatably connected to the inner wall of the accommodating chamber. The second drive screw and the second threaded sleeve are threadedly connected to drive the second threaded sleeve and the support plate to move horizontally.

[0011] Preferably, a driven gear is fixedly connected to the outer surface of the second drive screw, and the driven gear meshes with the linkage gear. A drive gear is fixedly connected to the output end of the second drive motor, and the drive gear meshes with the linkage gear.

[0012] Preferably, the horizontal drive mechanism includes a winch, which is fixed to one side of the inner wall of the receiving chamber. A guide shaft and a limiting ring are fixedly connected to the bottom of the inner wall of the receiving chamber. A control rope is connected to the winch, which passes through the bottom of the guide shaft and the limiting ring and is fixedly connected to the support plate.

[0013] Preferably, a tension spring is fixedly connected between the support plate and the limiting ring, and the tension spring exerts a tension on the support plate to accommodate the outside of the chamber.

[0014] Preferably, the receiving compartment is provided with two guiding mechanisms. The two guiding mechanisms include a fixed rod, one end of which is fixed to one side of the inner wall of the receiving compartment, and a fixing member is fixedly connected to the bottom of the fixed rod. The bottom of the fixing member is fixedly connected to the bottom of the inner wall of the receiving compartment. A sliding sleeve is slidably connected to the fixed rod. The bottom of the sliding sleeve adopts a notch design, and the sliding sleeve and the support plate are fixedly connected.

[0015] Preferably, a limiting vertical plate is fixedly connected to the fixing member, and a counteracting horizontal plate that cooperates with the limiting vertical plate is fixedly connected to one side of the sliding sleeve.

The opening end of the receiving compartment and the side of the live broadcast vehicle compartment are located on the same plane. The receiving compartment is fixed to the side of the live broadcast vehicle compartment in a concave manner. The antenna body can move laterally to the outside of the receiving compartment and the live broadcast vehicle compartment.

[0017] The beneficial effects of this utility model are: This invention, by installing the receiving compartment inside the mobile live broadcast vehicle and using a horizontal drive mechanism to drive the support plate to move horizontally, can push the antenna body laterally from the inside to the outside of the mobile live broadcast vehicle. Then, the telescopic cylinder drives the antenna body to move upward, which can quickly complete the release and use of the antenna. Conversely, the telescopic cylinder drives the antenna body to move, and the support plate can drive the antenna body to be retracted into the receiving compartment, avoiding the antenna being too high and affecting the mobile live broadcast vehicle's passage through height-restricted areas.

[0018] The side-hidden antenna structure proposed in this utility model does not occupy the space on the roof of the mobile live broadcast vehicle when the antenna is hidden or in use. It can avoid space competition between the antenna and equipment such as the PTZ camera and the lifting light on the roof of the live broadcast vehicle, ensuring the coexistence of multiple devices on the roof of the mobile live broadcast vehicle. At the same time, it makes the antenna easier to access, and maintenance does not require climbing the roof, thus improving operational safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A side-mounted concealed antenna structure includes a housing 1. One side of the housing 1 has an open design, and a horizontally movable closing baffle 2 is provided on one side of the housing 1. The closing baffle 2 can close the opening of the housing 1. When the closing baffle 2 closes the housing 1, its surface is exactly at the same level as the side of the live broadcast vehicle compartment, thus closing the opening of the live broadcast vehicle compartment. A locking mechanism can be installed between the closing baffle 2 and the inner wall of the housing 1. When the closing baffle 2 closes the housing 1, the closing baffle 2 is locked. The locking mechanism is existing technology (such as mechanical lock, electromagnetic lock, clamping parts, etc.), which will not be described in detail here. The interior of the housing 1 is equipped with an antenna body 3 that can extend outward and move upward. The bottom of the antenna body 3 is equipped with a support plate 4 that can move outward from inside the housing 1. The support plate 4 and the antenna body 3 are not fixed and do not affect the upward movement of the antenna body 3.

[0023] This application uses phased array technology to divide the communication frequency band, and the antenna operating frequency band is staggered from the PTZ camera control signal (usually 2.4GHz / 5.8GHz) by at least 200MHz bandwidth; The interior of the containment chamber 1 is lined with conductive foam (shielding effectiveness ≥70dB), and the cables are double-shielded coaxial cables (attenuation <0.5dB / m), which meet the IP67 protection standard. The antenna body 3 integrates a bidirectional dynamic compensation module (supporting 5G frequency bands such as n41 / n77 / n78), which compensates for the 2-3dB path loss caused by side deployment through microsecond-level frequency band switching technology. Actual tests show that the throughput is increased by 2-3 times in mountainous scenarios, which can effectively ensure that the signal does not attenuate. At the same time, the antenna will not interfere with the existing PTZ camera when changing position.

[0024] The hardware and software systems in the antenna body 3 and the mobile live broadcast vehicle are all existing technologies. This application does not involve improvements to the hardware or related software of the antenna body 3, but only to improvements to the antenna hiding and usage structure. There is no compatibility issue between the antenna body and the software system.

[0025] A telescopic cylinder 5 is fixedly connected to the top of the support plate 4. A cylindrical movable sleeve 6 is fixedly connected to the top of the telescopic cylinder 5. The cylindrical movable sleeve 6 is sleeved on the outer surface of the telescopic cylinder 5. By telescopically extending and retracting the telescopic cylinder 5, the cylindrical movable sleeve 6 can be moved up and down. Both one side of the telescopic cylinder 5 and the bottom of the antenna body 3 have wiring interfaces. The connection lines between the telescopic cylinder 5 and the antenna body 3 can be connected when the support plate 4 moves the antenna body 3 and the telescopic cylinder 5 to the outside of the housing 1. The interfaces of the telescopic cylinder 5 and the antenna body 3 adopt the waterproof interfaces in the prior art, and the connectors of the external wiring adopt the waterproof connectors in the prior art, which is convenient for outdoor use. When the antenna body 3 and telescopic cylinder 5 need to be retracted into the housing 1 by the support plate 4, the external wiring connector should first be separated from the telescopic cylinder 5 and the antenna body 3.

[0026] A connector 7 is fixedly connected between the cylindrical movable sleeve 6 and the antenna body 3. The connector 7 includes two ring-shaped mechanisms fixed together. The two ring-shaped structures are respectively fixed on the surfaces of the cylindrical movable sleeve 6 and the antenna body 3, so that when the cylindrical movable sleeve 6 moves up and down, the antenna body 3 can be driven to move up and down through the connector 7. The container 1 is equipped with two guiding mechanisms. The two guiding mechanisms include a fixed rod 8. One end of the fixed rod 8 is fixed to one side of the inner wall of the container 1. The bottom of the fixed rod 8 is fixedly connected to a fixing part 9. The bottom of the fixing part 9 is fixedly connected to the bottom of the inner wall of the container 1, which improves the stability of the fixed rod 8 and makes the force point of the fixed rod 8 connected to the bottom of the container 1, so that it will not tip over. A sliding sleeve 10 is slidably connected to the fixed rod 8. The bottom of the sliding sleeve 10 adopts a notch design, and the bottom of the fixing part 9 can extend from the notch at the bottom of the sliding sleeve 10. When fixing the fixed rod 8, it does not affect the horizontal sliding of the sliding sleeve 10 on the fixed rod 8. The sliding sleeve 10 is fixedly connected to the sealing baffle 2 at one end facing the outside of the receiving chamber 1, which can drive the sealing baffle 2 to move together. The inner side of the sealing baffle 2 has a sealing gasket, which allows the sealing baffle 2 to better seal the receiving chamber 1.

[0027] A limiting vertical plate 11 is fixedly connected to the fixing member 9, and an abutting horizontal plate 12 is fixedly connected to one side of the sliding sleeve 10. When the sliding sleeve 10 slides on the fixing rod 8 to the outside of the receiving chamber 1, the abutting horizontal plate 12 will eventually abut against the limiting vertical plate 11, thus limiting the maximum sliding distance of the sliding sleeve 10. The two sliding sleeves 10 are fixedly connected to the two sides of the support plate 4 respectively, so that the support plate 4 and the sliding sleeves 10 can move horizontally together.

[0028] The container 1 is equipped with a horizontal drive mechanism, which is used to drive the support plate 4 to slide horizontally. In Embodiment 1, the horizontal drive mechanism includes a first drive motor 101 and a first threaded sleeve 102. The first drive motor 101 can draw power from the mobile live broadcast vehicle, and the line passes through the receiving compartment 1. The first threaded sleeve 102 is fixed to one end of the support plate 4, and the first drive motor 101 is fixed inside the receiving compartment 1. The output end of the first drive motor 101 is fixedly connected to a first drive screw 103. The first drive screw 103 and the first threaded sleeve 102 are threadedly connected, so that when the first drive motor 101 drives the first drive screw 103 to rotate in different directions, it can drive the first threaded sleeve 102 and the support plate 4 to move horizontally. The support plate 4 drives the telescopic cylinder 5 and the antenna body 3 to move horizontally.

[0029] The support plate 4 has an opening, so that when the support plate 4 moves into the receiving chamber 1, the first drive screw 103 can pass through the support plate 4.

[0030] Example 2: In Example 2, the horizontal drive mechanism includes a second drive motor 201 and a second threaded sleeve 207. The second drive motor 201 can draw power from the mobile live broadcast vehicle. The line passes through the storage compartment 1. A motor bracket 202 is fixedly connected to one side of the inner wall of the storage compartment 1. The second drive motor 201 is fixedly installed on the motor bracket 202. The second threaded sleeve 207 is fixed to one end of the support plate 4. A second drive screw 203 and a linkage gear 204 are rotatably connected to the inner wall of the storage compartment 1. The second drive screw 203 and the second threaded sleeve 207 are threadedly connected. A driven gear 205 is fixedly connected to the outer surface of the second drive screw 203. The linkage gear 204 and the driven gear 205 mesh with each other. A drive gear 206 is fixedly connected to the output end of the second drive motor 201. The drive gear 206 and the linkage gear 204 mesh with each other. The size of the drive gear 206, the linkage gear 204, and the driven gear 205 decreases sequentially, and the number of teeth also decreases sequentially. This allows the drive gear 206 to drive the linkage gear 204 to rotate, and the linkage gear 204 to drive the driven gear 205 and the second drive screw 203 to rotate. This amplifies the torque, better drives the support plate 4 to move the antenna body 3 and the telescopic cylinder 5, and allows the output of the second drive motor 201 to drive the second drive screw 203 after deceleration, thus improving the control accuracy of the rotation of the second drive screw 203.

[0031] When the second drive motor 201 rotates in different directions, it can eventually drive the second drive screw 203 to rotate in different directions, which can drive the second threaded sleeve 207 and the support plate 4 to move horizontally. The support plate 4 drives the telescopic cylinder 5 and the antenna body 3 to move horizontally.

[0032] The support plate 4 has an opening, so that when the support plate 4 moves into the receiving chamber 1, the second drive screw 203 can pass through the support plate 4.

[0033] Meanwhile, compared with the first embodiment, in the second embodiment, the second drive motor 201 is fixed above the second drive screw 203 by the motor bracket 202, so that the second drive motor 201 does not need to be coaxial with the second drive screw 203, and the second drive motor 201 does not need to be fixed to the inner bottom of the receiving chamber 1. This can relatively reduce the height of the second drive screw 203 and the support plate 4, making the support plate 4 more stable.

[0034] Example 3: In Example 3, the horizontal drive mechanism includes a winch 301, which can draw power from the mobile live broadcast vehicle. The power line passes through the receiving chamber 1. The winch 301 is fixed to one side of the inner wall of the receiving chamber 1. A guide shaft 302 and a limiting ring 303 are fixedly connected to the bottom of the inner wall of the receiving chamber 1. A control rope 304 is connected to the winch 301. The control rope 304 passes through the bottom of the guide shaft 302 and the limiting ring 303 and is fixedly connected to the support plate 4. The direction of movement of the control rope 304 can be changed by using the guide shaft 302. The limiting ring 303 has an opening to facilitate the passage of the control rope 304. A tension spring 305 is fixedly connected between the support plate 4 and the limiting ring 303. The tension spring 305 exerts tension on the support plate 4 outward to the outside of the receiving chamber 1.

[0035] When the winch 301 releases the control rope 304, the tension spring 305 extends and pushes the support plate 4. The support plate 4 drives the telescopic cylinder 5 and the antenna body 3 to move horizontally to the outside of the receiving chamber 1. Conversely, when the winch 301 winds the control rope 304, it can pull the support plate 4 into the receiving chamber 1. The support plate 4 drives the telescopic cylinder 5 and the antenna body 3 to move horizontally into the receiving chamber 1.

[0036] Compared with Embodiment 2, the winch 301 can achieve slippage protection through the clutch to avoid damage to the mechanism; the screw drive is prone to deformation of the lead screw due to overload, which improves the service life of the equipment. At the same time, since the tension spring 305 is used to push the support plate 4 and simultaneously open the closed baffle 2, if there are objects or pedestrians outside the carriage during the opening of the closed baffle 2, it can provide a certain elastic protection and will not cause excessive pressure on the outside, thus ensuring the safety of antenna deployment and retrieval.

[0037] To achieve automated control of the aforementioned drive mechanism, the horizontal drive mechanism (first drive motor 101, second drive motor 201, winch 301) and telescopic cylinder 5 of this utility model are all electrically connected to the central controller inside the mobile live broadcast vehicle.

[0038] The central controller is a prior art technology, such as a programmable logic controller (PLC) or an in-vehicle industrial computer. The central controller is pre-installed with control programs and can receive control signals from users (such as commands issued via buttons or touchscreens on the in-vehicle control panel) or external devices.

[0039] Its basic control logic is as follows: Deployment process: After receiving the "deploy antenna" command, the central controller first controls the horizontal drive mechanism (such as starting the first drive motor 101 to rotate forward) to drive the support plate 4 and the antenna body 3 to move horizontally to a predetermined position outside the receiving compartment 1. Subsequently, the controller sends an extension command to the telescopic cylinder 5, driving the antenna body 3 to rise to the working height.

[0040] Retraction process: After receiving the "retract antenna" command, the central controller first controls the telescopic cylinder 5 to retract, driving the antenna body 3 down onto the support plate 4. Subsequently, the controller controls the horizontal drive mechanism (such as starting the first drive motor 101 to reverse) to drive the entire component to move horizontally back into the receiving chamber 1 until the closing baffle 2 closes.

[0041] Interlocking and protection: Necessary interlocking logic can be set in the control program, for example: ensuring that the horizontal drive mechanism can only perform the retraction action after the antenna body 3 has been fully lowered into place, so as to prevent collision or interference; the system can be equipped with limit switches (not shown in the figure, which are existing technologies) to detect the extreme positions of the support plate 4 and the antenna body 3, and feed the detection signal back to the central controller, so that the controller can accurately stop the drive action.

[0042] The connection lines between the central controller and each drive mechanism use wiring harnesses and waterproof connectors commonly used in vehicle equipment. The specific circuit connections and control program writing are conventional technical means that can be implemented by those skilled in the art based on the structural description in this specification, and need not be elaborated.

[0043] like Figure 12 This application also provides a live broadcast vehicle, including a live broadcast vehicle compartment 100 and the aforementioned side-concealed antenna structure. In addition, the mobile live broadcast vehicle 100 is also equipped with an automobile chassis and power system, an integrated independent power supply system, a signal transmission and communication system, a program production system (including video and audio processing equipment), and is equipped with auxiliary facilities such as air conditioning, hydraulic support legs, lighting and storage space to form a comprehensive mobile technology platform. These components are all conventional settings of mobile live broadcast vehicles in the prior art, and this application does not involve any improvement to these conventional components, so they will not be described in detail here.

[0044] The live broadcast vehicle compartment 100 has a rectangular opening on one side, and the receiving compartment 1 is fixed at the rectangular opening on one side of the live broadcast vehicle compartment 100, with the opening of the receiving compartment 1 facing the outside of the live broadcast vehicle compartment 100; the top, bottom and sides of the receiving compartment 1 are fixed to the inner wall of the live broadcast vehicle compartment 100.

[0045] The working principle of the lateral hidden antenna structure and live broadcast vehicle provided by this utility model is as follows: Under the action of the horizontal drive mechanism, the support plate 4 can be driven to move horizontally, and the support plate 4 drives the telescopic cylinder 5 and the antenna body 3 to move horizontally. When the support plate 4 moves the telescopic cylinder 5 and the antenna body 3 to the outside of the receiving compartment 1 (the receiving compartment 1 is located in the opening on one side of the mobile live broadcast vehicle, at which time the telescopic cylinder 5 and the antenna body 3 will also move to the outside of the mobile live broadcast vehicle). Then, the telescopic cylinder 5 extends upward to push the cylindrical movable sleeve 6. The cylindrical movable sleeve 6 drives the antenna body 3 to move upward through the connector 7, so that the antenna body 3 moves upward to the top of the housing 1 and the side of the mobile live broadcast vehicle, releasing the antenna, reducing the obstruction or interference of the external environment on the antenna, and ensuring the communication efficiency of the mobile live broadcast vehicle. When the antenna needs to be retracted, the telescopic cylinder 5 retracts, causing the cylindrical movable sleeve 6 to move downwards. The cylindrical movable sleeve 6 causes the antenna body 3 to move downwards, and the horizontal drive mechanism drives the support plate 4 to move into the receiving chamber 1, so that the antenna body 3 is retracted into the receiving chamber 1. When the support plate 4 moves, it also causes the sliding sleeve 10 to slide on the fixed rod 8. One end of the sliding sleeve 10 drives the closing baffle 2 to move, closing the opening of the receiving chamber 1.

[0046] Compared with related technologies, the lateral hidden antenna structure and live broadcast vehicle provided by this utility model have the following beneficial effects: The side-hidden antenna structure proposed in this utility model does not occupy the space on the roof of the mobile live broadcast vehicle when the antenna is hidden or in use. It can avoid space competition between the antenna and equipment such as the PTZ camera and the lifting light on the roof of the live broadcast vehicle, ensuring the coexistence of multiple devices on the roof of the mobile live broadcast vehicle. At the same time, it makes the antenna easier to access, and maintenance does not require climbing the roof, thus improving operational safety.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
