[0052] Reference Figure 1 The Internet of Things antenna of the embodiment of the present invention comprises a first support rod 11, a second support rod 12, a bandwidth extension component 2, a plurality of radiation rods 3 and a plurality of protective covers 4. Among them, the first support rod 11 and the second support rod 12 are used to support other components and provide support. The second support rod 12 is vertically connected to the top of the first support rod 11, so that other antenna components can be arranged on the second support rod 12. The bandwidth extension component 2 is installed on the second support rod 12 to increase the available bandwidth of the communication channel, thereby improving the capacity and efficiency of data transmission. The bandwidth extension component 2 includes at least one group of extension units 20, each of which includes two extension rods 21. According to actual conditions, two groups of bandwidth extension units 20 can be arranged on both sides of the first support rod 11 along the second support rod 12. Among them, the two extension rods 21 are symmetrically connected to both sides of the second support rod 12, so that the electromagnetic field around the antenna is more uniform and better performance is achieved. The extension direction of each group of extension units 20 is perpendicular to the extension direction of the second support rod 12, so as to achieve the expansion of bandwidth. For ultra-wideband technology, the bandwidth extension component 2 can make its signal cover a larger bandwidth to achieve high-speed data transmission and improve the performance of the Internet of Things antenna.

[0053] like Figure 1As shown, the radiation rod 3 is mainly used to realize the conversion between electromagnetic waves and electrical signals. It is an important part of the IoT antenna and is used to radiate and receive electromagnetic waves to improve the signal gain of the IoT antenna. Multiple radiation rods 3 are symmetrically installed on both sides of the second support rod 12, and their length direction is perpendicular to the extension direction of the second support rod 12, and are all located on one side of the bandwidth extension component 2. According to actual conditions, every two radiation rods 3 can constitute a group of radiation units, and a connecting structure such as a mounting block can be set in the middle of each group of radiation units to symmetrically install the radiation rods 3 on the second support rod 12. The compact and symmetrical arrangement of the radiation rods 3 can effectively improve the gain of the IoT antenna, reduce interference, and increase the bandwidth to adapt to the use of ultra-wideband technology.

[0054] Reference Figure 2 , Figure 3 The protective cover 4 is used to protect the radiation rod 3, covers most of the area of ​​the radiation rod 3, blocks dust and reduces the contact between rain and the radiation rod 3. According to actual conditions, the length of the protective cover 4 can be the same as that of the radiation rod 3, or slightly shorter than the length of the radiation rod 3. The number of protective covers 4 is consistent with the number of radiation rods 3, and multiple protective covers 4 are respectively sleeved on the outside of multiple radiation rods 3. Each protective cover 4 includes at least two elastic components 44 and at least two protective structures 42. According to actual conditions, the number of elastic components 44 and protective structures 42 can be three, four or other numbers. All protective structures 42 are connected to form an annular structure through elastic components 44, that is, the number of protective structures 42 and elastic components 44 is the same. Each elastic component 44 includes multiple elastic units arranged along the length direction of the radiation rod 3, and the two ends of the multiple elastic units are respectively connected to the protective structure 42. According to actual conditions, the elastic unit can be a spring, a telescopic rod or other elastic structure. The protective structure 42 is connected by the elastic component 44 so that the protective structure 42 can accommodate radiation rods 3 of more sizes. By utilizing the elasticity of the elastic component 44 , the protective cover 4 can adapt to radiation rods 3 of more sizes and different diameters, thereby increasing the practicality of the protective cover 4 .

[0055] When it is necessary to put a protective cover 4 on the radiation rod 3, as shown in FIG. Figure 2-Figure 3As shown, the protective cover 4 is pulled apart by the elasticity of the elastic structure, so that the distance between the protective structures 42 is increased. At this time, the diameter of the annular structure formed by the multiple protective structures 42 is larger than the diameter of the radiation rod 3, and the operator can sleeve the protective cover 4 on the outside of the radiation rod 3. After the protective cover 4 is moved to a suitable position, the protective cover 4 is loosened. At this time, the protective structure 42 is radially contracted by the elastic force of the elastic structure, so that the protective structure 42 is tightly sleeved on the outside of the radiation rod 3, and the installation of the protective cover 4 is completed. When the protective cover 4 needs to be removed, the protective cover 4 is also pulled apart to separate the protective structure 42 from the radiation rod 3. At this time, the diameter of the annular structure formed by the multiple protective structures 42 is larger than the diameter of the radiation rod 3, and the operator can remove the protective cover 4 from the radiation rod 3. The setting of the elastic component 44 and the multiple protective structures 42 makes the protective cover 4 easy to take, which is convenient for the staff to regularly replace the protective cover 4, greatly reducing the maintenance workload of the staff. In addition, the protective cover 4 covers most parts of the radiation rod 3, which can effectively protect the radiation rod 3 and extend the life of the Internet of Things antenna.

[0056] In some embodiments, reference Figure 3 The protective structure 42 is a fan-shaped ring structure. The ring structure formed by multiple protective structures 42 can better wrap the radiation rod 3. According to the number of protective structures 42 and the shape of the radiation rod 3, the protective structure 42 can also be formed by other structures, such as a structure with a broken line cross section. All protective structures 42 of each protective cover 4 are arranged at equal intervals along the circumferential direction, that is, a ring structure is formed.

[0057] Reference Figure 3 In some embodiments, the protective structure 42 includes a fixing layer 421 and a protective layer 422. The protective layer 422 is used to protect the radiation rod 3 and achieve buffering and other functions. The fixing layer 421 is arranged outside the protective layer 422 and is used to connect with the elastic structure so that the protective structure 42 can be fixed on the radiation rod 3 by the elastic force provided by the elastic structure. At the same time, the center of the protective layer 422 is coaxial with the center of the fixing layer 421. Since the protective structure 42 is arranged at equal intervals and the elastic structure is connected to the fixing structure, the two centers of the protective layer 422 and the fixing layer 421 are coaxial, so that when the protective structure 42 is contracted by the elastic force of the elastic structure, the contraction direction of the protective layer 422 and the fixing layer 421 is the same, that is, the radial direction.

[0058] Reference Figure 5, the protective layer 422 includes a buffer pad 4221, an anti-skid pad 4222 and a plurality of adsorbents 4223. The outer surface of the buffer pad 4221 is connected to the fixed layer 421, and is used to form a buffer between the radiation rod 3 and the fixed layer 421, so as to prevent the vibration of the fixed layer 421 from being directly transmitted to the radiation rod 3 and affecting the radiation rod 3. According to the actual situation, the material of the buffer pad 4221 can be selected from foam material or other elastic and waterproof organic synthetic materials. The outer surface of the anti-skid pad 4222 is connected to the buffer pad 4221, and a part of the inner surface is in contact with the radiation rod 3, so as to increase the friction between the protective structure 42 and the radiation rod 3, so as to prevent the protective structure 42 from being fixed on the radiation rod 3 due to sliding, or from slipping off the radiation rod 3 in the event of bad weather outside and failing to achieve a good protection effect. The inner edge of the anti-skid pad 4222 is a waveform, which can achieve the effect of increasing friction and increase the contact area between the anti-skid pad 4222 and the radiation rod 3. The adsorption member 4223 is used to further fix the protective structure 42 and the radiation rod 3. A plurality of adsorption members 4223 are arranged on the inner side of the anti-slip pad 4222 along the length direction of the anti-slip pad 4222. According to actual conditions, the adsorption members 4223 can be arranged in multiple rows to achieve more stable adsorption. The material of the adsorption member 4223 can be selected from rubber material or other elastic and waterproof materials. When the protective cover 4 is installed, the protective structure 42 drives the adsorption member 4223 to contract radially. After the adsorption member 4223 contacts the radiation rod 3, it continues to be subjected to pressure and opens outward on the surface of the radiation rod 3. At this time, the inner and outer pressures of the inner wall of the adsorption member 4223 are different, so that the adsorption member 4223 can be adsorbed on the outer surface of the radiation rod 3, and the protective structure 42 can be fixed on the surface of the radiation rod 3.

[0059] Reference Figure 4The protective cover 4 also includes a shell structure 43, which is tilted and arranged outside the protective structure 42 located on the top surface, for blocking rain and dust, and rebounding and diverting rain to prevent it from staying for a long time and affecting the radiation rod 3 and the protective structure 42. The shell structure 43 includes a curved shell 435, a first elastic member 431 and a second elastic member 432. Among them, the curved shell 435 is tilted and arranged above the protective structure 42, and the distance between one side of the curved shell 435 and the protective structure 42 is greater than the distance between the other side and the protective structure 42. In other words, a certain angle is formed between the curved shell 435 and the protective structure 42, forming a slope. For the curved shell 435 arranged on both sides of the second support rod 12, according to actual conditions, the tilting directions can be the same or opposite. When dust falls, large pieces of dust can roll down along the slope formed by the curved shell 435 to avoid dust accumulation. When it rains, the falling raindrops slide down along the curved cover 435 or are directly rebounded due to their own gravity. At the same time, the rain falling on the surface of the curved cover 435 can also take away the fine dust gathered on the surface of the curved cover 435, flush the curved cover 435 clean, and prevent dust and dirt from staying on the curved cover 435 for a long time, thereby extending the service life of the IoT antenna. The curved cover 435 can prevent most dust and rainwater from falling into the gap of the protective structure 42. For dust and rainwater falling into the gap of the protective structure 42, since the protective structure 42 is made of waterproof material and multiple protective structures 42 are connected only by elastic structures, the rainwater can carry the dust along the gap between the protective structures 42 to the axial direction of the protective structure 42 and flow out of the protective structure 42 without staying for a long time, thereby avoiding the corrosion of the protective structure 42 and the radiation rod 3 by rainwater and dust, thereby extending the service life of the IoT antenna.

[0060] The first elastic member 431 and the second elastic member 432 provide elastic force for the movement of the curved cover 435 on the protective structure 42, and buffer the impact of rainwater to prevent the radiation rod 3 from being affected. Figure 4As shown. Among them, the first elastic member 431 is arranged on the side with a larger distance between the curved cover 435 and the fixed layer 421, and its two ends are respectively connected to the curved cover 435 and the fixed layer 421. According to actual conditions, the first elastic member 431 can be a rod-shaped structure, a spring or other elastic structure made of elastic material. The second elastic member 432 is arranged in the middle of the lower end surface of the curved cover 435, and the two ends of the second elastic member 432 are respectively connected to the curved cover 435 and the fixed layer 421. When the curved cover 435 is impacted by the outside world, since the positions of the first elastic member 431 and the second elastic member 432 are biased toward the side with a larger distance between the curved cover 435 and the fixed layer 421, the external impact will cause the curved cover 435 to move more on the side with a smaller distance from the fixed layer 421, and make the curved cover 435 more inclined, so that rainwater can slide down along the outer surface of the curved cover 435 faster, and rainwater can better wash away the surface dust, avoid being left on the curved cover 435, and extend the service life of the Internet of Things antenna.

[0061] In some embodiments, reference Figure 4 , the second elastic member 432 includes a support seat 4321 and at least one movable rod 4322. According to the actual situation and the structural size, the second elastic member 432 can also be replaced by a structure made of a spring or elastic material. One end of at least one movable rod 4322 extends into the support seat 4321 arranged outside the fixed layer 421, and is movably connected to the support seat 4321. The other end of the movable rod 4322 is connected to the curved cover 435, and is affected by the curved cover 435 to move in the support seat 4321. A cavity is provided inside the support seat 4321, and liquid is injected into the cavity to buffer the movement of the movable rod 4322. According to the actual situation, the bottom of the support seat 4321 may be an open bottom, and after being connected to the fixed layer 421 of the protective structure 42, it forms a cavity together with the surface of the fixed layer 421, and the liquid inside the cavity is in contact with the fixed layer 421. In some embodiments, the bottom of the support seat 4321 may also be a closed bottom, and the liquid inside the cavity does not contact the fixed layer 421. In some embodiments, the number of movable rods 4322 is two, and the two movable rods 4322 are bar-shaped movable rods 4322, and extend along the length direction of the protection structure 42. Since the vertical cross-sectional shape of the support seat 4321 matches the setting of the movable rod 4322, when the number of movable rods 4322 is two, the support seat 4321 is a U-shaped structure, and the two movable rods 4322 extend from both sides of the support seat 4321 to realize active connection.

[0062] Reference Figure 6, the vertical cross-section of the movable rod 4322 is an inverted T-shape, including a support rod 4323 and an elastic part 4324, and the elastic part 4324 is arranged at the bottom end of the support rod 4323 and has elasticity. According to the actual situation, an elastic gasket or a rubber sealing ring can be selected as the elastic part 4324, and the movable rod 4322 extends into the support seat 4321 through the elastic part 4324. When installing the second elastic member 432, first complete the installation of the support seat 4321 so that the support seat 4321 and the surface of the fixed layer 421 form a cavity together, and then inject liquid into the cavity through the opening at the top of the support seat 4321 for active connection with the movable rod 4322. According to the actual situation, water or oil can be selected as the injection liquid. After completing the liquid injection, the two movable rods 4322 are installed through the openings on the protrusions on both sides of the U-shaped structure of the support seat. In order to prevent the movable rod 4322 from slipping out of the support seat 4321, the size of the elastic part 4324 is larger than the top opening of the support seat 4321, so the movable rod 4322 needs to be able to extend into the support seat 4321 through the deformation of the elastic part 4324. After the elastic part 4324 enters the support seat 4321, due to its own elastic recovery shape, the movable rod 4322 will not fall out of the support seat 4321. At the same time, since the size of the elastic part 4324 is larger than the top opening of the support part, and its material is an elastic gasket or a rubber sealing ring, it has a certain sealing effect, and can also prevent the liquid in the cavity from overflowing when the protective cover 4 moves.

[0063] The curved cover 435 is connected to the protective structure 42 through the first elastic member 431 and the second elastic member 432. Figure 4 When rain falls on the curved cover 435, the curved cover 435 is impacted by the rain, driving the two movable rods 4322 to move in the support seat 4321, and the liquid in the support seat 4321 buffers the movement of the two movable rods 4322 to avoid damage to the cover structure 43. When the rain stops and the curved cover 435 is no longer impacted by the rain, the liquid level in the cavity returns to a stable state, and the two movable rods 4322 return to their original positions, realizing the reset of the cover structure 43.

[0064] Reference Figure 1In some embodiments, the IoT antenna further includes a vibrator 5, a reflective component 7, and a lightning rod 6. The vibrator 5 is used to guide and amplify electromagnetic wave signals, so that the IoT antenna can send and receive stronger electromagnetic signals. The vibrator 5 is a ring-shaped vibrator, which is installed on the second support rod 12 through the mounting structure in the middle thereof. The second support rod 12 passes through the middle of the vibrator 5 by the mounting structure, and the vibrator 5 is divided into two parts that are symmetrical about the second support rod 12. The vibrator 5 and the multiple radiation rods 3 are arranged on the same side of the first support rod 11 and are located between the two groups of bandwidth extension units 20. The vibrator 5 can enhance the signal transmitted from the space and guide it to the radiation rod 3. At the same time, the signal emitted by the radiation rod 3 can also be enhanced and amplified by the vibrator 5 to obtain a better transmission effect.

[0065] The reflective component 7 is disposed between the radiation rod 3 and the vibrator 5, and is bent toward one side of the vibrator 5. Figure 1 As shown. The reflection assembly 7 includes a main rod 71 and a plurality of reflection rods 72, the plurality of reflection rods 72 are symmetrically distributed on both sides of the main rod 71, and the extension direction of the plurality of reflection rods 72 is parallel to the extension direction of the radiation rod 3. According to actual conditions, the main rod 71 may be an arc rod, or a broken line rod structure may be adopted. The second support rod 12 passes through the middle of the main rod 71, dividing the reflection assembly 7 into two parts symmetrical about the second support rod 12. The reflection assembly 7 can reflect the signal processed by the vibrator 5, enhance the signal strength and radiation strength, and improve the quality of information transmission.

[0066] Reference Figure 1 , the lightning rod 6 is arranged at one end of the second support rod 12 away from the radiation rod 3. In some embodiments, the lightning rod 6 is arranged on the bandwidth extension unit 20 located at one end of the second support rod 12, and is perpendicular to the second support rod 12. The lightning rod 6 is used to protect the IoT antenna from being damaged by voltage spikes caused by lightning, thereby extending the life of the IoT antenna.
