Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric drive technology, specifically relating to an antenna structure that can automatically deploy. Background Technology
[0002] With the rapid development of modern communication technology, antennas, as key devices for signal transmission, have attracted much attention for their performance and convenience. Traditional antenna structures have many shortcomings in terms of deployment and storage, which seriously affect their efficiency and the expansion of application scenarios.
[0003] Many existing antenna structures employ manual deployment, which is cumbersome and time-consuming. In scenarios requiring rapid antenna deployment, such as emergency communications and military operations, this approach cannot meet the need to quickly establish communication links. Furthermore, some automatically deployable antenna structures are complex in design, expensive, unreliable, and prone to mechanical failures, causing the antenna to fail to deploy or retract properly, thus affecting the stability of the communication system. In addition, in some special environments, such as strong winds and vibrations, these antenna structures lack effective protection and stabilization measures, making them easily damaged and incurring high maintenance costs, thus limiting their application in harsh environments.
[0004] Authorized publication number "CN210351840U" describes an automatic unfolding and folding structure for antenna attitude adjustment, comprising: a housing mounted on a base plate for mounting supporting equipment and an antenna; a protective structure rotatably connected around the housing; and a drive unit installed inside the housing for driving the protective structure to unfold or close, thereby protecting the supporting equipment and antenna. This unfolding and folding mechanism can solve the problem of rapid adjustment of antenna attitude in the case of rapid deployment of antenna equipment; it can maintain normal operation even when randomly deployed from a height of two meters, while protecting the internal equipment and antenna; and it is easy to operate.
[0005] The aforementioned patent can solve the problem of quickly adjusting the antenna attitude of the equipment in the case of rapid deployment of antenna equipment; it can maintain normal operation even when randomly deployed at a height of two meters, while protecting the internal equipment and antenna; it is easy to operate, but the above patent has certain limitations in use. Because the antenna lacks convenience when folding and unfolding, the operation process must be assisted by construction personnel, which not only makes the operation of the equipment extremely inconvenient, but also makes the subsequent deployment and retrieval operations equally troublesome. Utility Model Content
[0006] The purpose of this invention is to provide an antenna structure that can be automatically deployed, in order to solve the problem that in the prior art, the antenna lacks convenience when folding, deploying and unfolding, and the operation process requires the assistance of construction personnel. This not only makes the operation of the equipment extremely inconvenient, but also makes the subsequent deployment and retraction operations equally troublesome.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An antenna structure capable of automatic deployment includes:
[0009] A support base, the top of which is fixedly connected to a limiting frame, and the bottom of which is fixedly connected to a motor;
[0010] A lead screw, which is rotatably connected to a limiting frame and a support base, and is fixedly connected to the output end;
[0011] Nut sleeve, the nut sleeve being threadedly connected to the circumferential surface of the lead screw;
[0012] The antenna deployment plate is provided in four parts, and all four antenna deployment plates are slidably connected within the limiting frame.
[0013] The deployment mechanism is located on the upper side of the support base and is used to adjust the four antenna deployment plates.
[0014] As a preferred embodiment of this utility model, the unfolding mechanism includes:
[0015] The connecting plate is provided in four parts, and all four connecting plates are fixedly connected to the circumferential surface of the nut sleeve;
[0016] The device has eight movable rods, each of which is rotatably connected to both ends of four connecting plates via a rotating shaft. The other ends of the eight movable rods are also rotatably connected to the adjacent ends of four antenna deployment plates via rotating shafts.
[0017] As a preferred embodiment of this utility model, each of the four antenna deployment plates has an antenna arc plate fixedly connected to its far-away ends, and each of the four antenna arc plates has two positioning holes at its far-away ends.
[0018] As a preferred embodiment of this utility model, a positioning hole is provided at the top of the lead screw, a limiting cover is provided on the upper side of the lead screw, a positioning pin is movably engaged in the positioning hole, and the limiting cover is movably engaged between the positioning pin and the lead screw.
[0019] As a preferred embodiment of this utility model, an edge protection ring is fixedly connected to the circumferential surface of the support base.
[0020] As a preferred embodiment of this utility model, the bottom end of the support base is fixedly connected to four connecting seats, and the adjacent ends of the four connecting seats are all fixedly connected to a fixing plate.
[0021] As a preferred embodiment of this utility model, the top of the support base is provided with multiple reserved holes.
[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] 1. In this solution, the automatic deployment and retraction of the antenna deployment plate is achieved by the transmission cooperation between the motor-driven lead screw and the nut sleeve. After the motor starts, the lead screw rotates stably and the nut sleeve moves linearly. Through the linkage of the connecting plate and the movable rod, the antenna deployment plate is precisely pushed or pulled along the track of the limiting frame. No manual assistance is required, and the antenna can be quickly and accurately switched between different states. This greatly improves the convenience and efficiency of operation, meets the needs of rapid deployment and storage of antennas in scenarios such as emergency communication and military operations, and effectively improves the efficiency and flexibility of antenna use.
[0024] 2. In this solution, the stable connection between the lead screw and the motor output end, as well as the support base and the limiting frame, ensures that there is no deviation or shaking during the rotation process. The nut sleeve can move smoothly in a straight line. The design of the positioning hole, limiting cover and positioning pin at the top of the lead screw further ensures that the lead screw rotates stably under various working conditions, avoids abnormal axial displacement, thereby ensuring the normal operation of the deployment mechanism, reducing the probability of mechanical failure, enabling the antenna to be deployed and retracted stably, maintaining the stability of the communication system, reducing communication interruptions caused by antenna failure, and reducing maintenance costs and usage risks.
[0025] 3. In this solution, the edge protection ring on the circumferential surface of the support base can effectively block collisions with external objects and prevent accidental contact by personnel, protecting internal components from damage. In bumpy environments such as vehicle mounting or harsh natural environments such as strong winds and vibrations, it can maintain the integrity and stability of the antenna structure and ensure normal operation of the antenna. At the same time, the design of the connecting seat and fixing plate at the bottom of the support base ensures a stable connection of the antenna on the mounting surface, enhances the anti-interference capability of the overall structure in special environments, expands the applicable environment range of the antenna, and improves the reliability and continuity of communication.

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1
[0034] Please see Figures 1-4 The present invention provides the following technical solution:
[0035] An antenna structure capable of automatic deployment includes:
[0036] Support base 1, with a limit frame 3 fixedly connected to the top of support base 1, and a motor 12 fixedly connected to the bottom of support base 1;
[0037] Lead screw 8 is rotatably connected to the limiting frame 3 and the support base 1, and is fixedly connected to the output end of 102;
[0038] Nut sleeve 6 is threaded onto the circumferential surface of lead screw 8;
[0039] Antenna deployment plate 5, there are four antenna deployment plates 5, and all four antenna deployment plates 5 are slidably connected within the limiting frame 3;
[0040] The deployment mechanism is located on the upper side of the support base 1 and is used to adjust the four antenna deployment plates 5.
[0041] In a specific embodiment of this utility model, the support base 1 serves as the basic support component of the entire antenna structure, playing the role of stabilizing the placement and bearing other components.
[0042] The top of the support base 1 is fixedly connected to the limiting frame 3, providing a stable installation base for the limiting frame 3 and ensuring the stability of the upper structure.
[0043] The bottom of the support base 1 is fixedly connected to the motor 12, providing an installation position for the motor 12, ensuring that the motor 12 can operate stably, and effectively transmitting the power of the motor 12 to the lead screw 8, thereby driving the entire antenna to unfold.
[0044] The motor 12 serves as a power source, providing power for the rotation of the lead screw 8. The operation of the motor 12 drives the lead screw 8 to rotate, converting electrical energy into mechanical energy, thereby enabling a series of subsequent actions related to antenna deployment.
[0045] The lead screw 8 is fixedly connected to the output end of the motor 12, receives the power transmitted by the motor 12, and realizes its own rotation.
[0046] The lead screw 8 is rotatably connected to the limiting frame 3 and the support base 1 to ensure the stability of the lead screw 8 during rotation, preventing deviation or shaking, and ensuring that the nut sleeve 6 can move smoothly in a straight line along the lead screw 8.
[0047] The lead screw 8 converts its rotational motion into the linear motion of the nut sleeve 6 through a threaded connection with the nut sleeve 6, thereby pushing or pulling the components associated with the nut sleeve 6 to achieve the antenna deployment action.
[0048] Nut sleeve 6 is threadedly connected to lead screw 8. When lead screw 8 rotates, according to the principle of thread transmission, nut sleeve 6 will move linearly along the circumferential surface of lead screw 8.
[0049] Its linear motion can drive other connected components, such as the antenna deployment plate 5, thereby enabling the antenna deployment plate 5 to move and thus completing the antenna deployment action.
[0050] There are four antenna deployment plates 5, which are key components of the antenna and are used to realize the antenna signal transmission and reception functions.
[0051] All are slidably connected within the limiting frame 3, which provides a specific sliding track for the antenna deployment plate 5, ensuring that the movement trajectory of the antenna deployment plate 5 is stable and controllable during deployment and retraction. Driven by the lead screw 8 and the nut sleeve 6, the antenna deployment plate 5 can slide along the track of the limiting frame 3, thereby realizing the change of the antenna from the retracted state to the deployed state.
[0052] The deployment mechanism is located on the upper side of the support base 1, and its main function is to adjust the four antenna deployment plates 5.
[0053] Through the operation of this mechanism, parameters such as the deployment angle, speed, and position of the antenna deployment plate 5 can be controlled to ensure that the antenna can be deployed in a suitable manner to meet different usage needs and signal transmission requirements. For example, the angle of the antenna deployment plate 5 can be adjusted according to different signal strength and direction requirements to achieve the best signal reception and transmission effect. It should be noted that the specific model of motor 12 used shall be selected by those skilled in the art, and the above-mentioned zzz etc. are all existing technologies, which will not be elaborated in this solution.
[0054] Please refer to the details. Figures 1-4 The participating organizations include:
[0055] There are four connecting plates 11, and all four connecting plates 11 are fixedly connected to the circumferential surface of the nut sleeve 6.
[0056] There are eight movable rods 10. The eight movable rods 10 are rotatably connected to the two ends of the four connecting plates 11 via rotating shafts. The other ends of the eight movable rods 10 are rotatably connected to the adjacent ends of the four antenna deployment plates 5 via rotating shafts.
[0057] In this embodiment: When the motor 12 starts, the output end of the motor 12 drives the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the nut sleeve 6, the nut sleeve 6 will move linearly along the circumferential surface of the lead screw 8. The four connecting plates 11 fixed to the circumferential surface of the nut sleeve 6 move together with the nut sleeve 6.
[0058] Movable rods 10 connected to both ends of the connecting plate 11 move linearly with the connecting plate 11 at one end, and rotate around the pivot connected to the antenna deployment plate 5 at the other end, thereby pushing the antenna deployment plate 5 to slide along the track within the limiting frame 3. Because there are four antenna deployment plates 5 connected in a specific way, under the action of the movable rods 10, the four antenna deployment plates 5 will expand outward synchronously until they reach the predetermined deployment angle and position, thus realizing the deployment of the antenna.
[0059] When the antenna needs to be retracted, the output shaft of motor 12 reverses, the lead screw 8 rotates in the opposite direction, and the nut sleeve 6 moves linearly in the opposite direction, driving the connecting plate 11 and the movable rod 10 to move in the opposite direction, thereby pulling the antenna deployment plate 5 to slide inward along the track of the limiting frame 3, completing the antenna retraction action. Throughout the process, the deployment mechanism precisely controls the deployment angle, speed, and position of the antenna deployment plate 5 through ingenious connection and motion transformation to meet different usage requirements.
[0060] Please refer to the details. Figures 1-3 Each of the four antenna deployment plates 5 has an antenna arc plate 4 fixedly connected to its far end, and each of the four antenna arc plates 4 has two positioning holes 401.
[0061] In this embodiment: During antenna deployment and use, the antenna arc plate 4 closely cooperates with the movement of the antenna deployment plate 5 to ensure efficient signal transmission and reception. The positioning hole 401 provides a standardized interface for antenna function expansion and installation. When signal enhancement components need to be installed, bolts or other connectors are used to pass through the positioning hole 401 to fix the components to the antenna arc plate 4 and connect them to the antenna's circuit system, thereby improving the antenna's signal processing capabilities.
[0062] Please refer to the details. Figure 2 The top of the lead screw 8 is provided with a positioning hole 401, and the upper side of the lead screw 8 is provided with a limiting cover 7. A positioning pin 9 is movably engaged in the positioning hole 401, and the limiting cover 7 is movably engaged between the positioning pin 9 and the lead screw 8.
[0063] In this embodiment: During the installation of the lead screw 8, the positioning pin 9 is first inserted into the positioning hole 401 at the top of the lead screw 8, and then the limiting cover 7 is carefully snapped between the positioning pin 9 and the lead screw 8. When the motor 12 drives the lead screw 8 to rotate, the limiting cover 7 and the positioning pin 9 work together to ensure that the lead screw 8 rotates stably even when it rotates at high speed or is subjected to a large load, and there will be no abnormal axial displacement. This, in turn, ensures that the nut sleeve 6 can move smoothly in a straight line along the lead screw 8, ensuring that the deployment mechanism connected to it can operate normally, and realizing the precise deployment and retraction of the antenna deployment plate 5.
[0064] Please refer to the details. Figures 1-4 An edge protection ring 101 is fixedly connected to the circumferential surface of the support base 1.
[0065] In this embodiment, the edge protection ring 101 always surrounds the support base 1 for protection.
[0066] Please refer to the details. Figures 1-3 The bottom end of the support base 1 is fixedly connected to four connecting bases 2, and the adjacent ends of the four connecting bases 2 are all fixedly connected to a fixing plate 201.
[0067] In this embodiment: When installing the antenna, technicians accurately align the mounting plate 201 with the installation position of other equipment and select a suitable fixing method according to the actual situation, such as using bolts to fasten the mounting plate 201 to the screw holes on the mounting surface, or using welding to firmly weld the mounting plate 201 to the mounting surface. The connecting seat 2 ensures that the connection between the support seat 1 and the mounting surface is stable and reliable, so that the entire antenna structure can be firmly installed at the target position. In the application scenario of vehicle-mounted antennas, the mounting plate 201 can be installed at a specific position on the roof of the vehicle. The connecting seat 2 ensures that the antenna structure remains stable during vehicle travel, even when encountering bumpy roads, providing a stable foundation for the normal operation of the antenna.
[0068] Please refer to the details. Figures 1-4 The top of the support base 1 has multiple pre-drilled holes.
[0069] In this embodiment, the top of the support base 1 has multiple pre-drilled holes, which facilitate the functional expansion and stability enhancement of the antenna structure. These holes can be used to install other auxiliary equipment, such as signal amplifiers and control modules. Through these pre-drilled holes, these devices can be easily and quickly connected to the antenna structure, thus expanding the antenna's functionality.
[0070] The working principle and usage process of this utility model are as follows: During deployment, the motor 12 is first started. The motor 12 drives the lead screw 8 to rotate. Because the lead screw 8 is fixed to the output end of the motor 12 and rotatably connected within the limiting frame 3 and the support base 1, it can rotate stably, converting electrical energy into mechanical energy. Next, the rotation of the lead screw 8 causes the nut sleeve 6 to move linearly along its circumference. The four connecting plates 11 fixed to the nut sleeve 6 move linearly accordingly. The movable rods 10 connected to both ends of the connecting plates 11 move with one end along the connecting plate 11, and the other end rotates around the shaft connected to the antenna deployment plate 5, pushing the four antenna deployment plates 5 to slide synchronously outward along the inner track of the limiting frame 3 until the predetermined deployment angle and position are reached, achieving automatic deployment without manual assistance. During retraction, the output shaft of the control motor 12 is reversed, the lead screw 8 rotates in the opposite direction, and the nut sleeve 6 moves linearly in the opposite direction, driving the connecting plates 11 and the movable rods 10 to move in the opposite direction. The movable rods 10 pull the antenna deployment plates 5 to slide inward along the track of the limiting frame 3, completing the antenna retraction. The entire process is simple and efficient.
[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
