Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna assembly and a mobile router. Background Technology

[0002] Mobile routers are portable and can share a network for multiple terminal devices, making them suitable for outdoor office, travel, and in-vehicle scenarios.

[0003] Current mobile routers, due to size limitations, have relatively low antenna performance, which can easily lead to network lag and unstable network speeds. Utility Model Content

[0004] This application provides an antenna assembly and a mobile router, which helps to improve the antenna performance of the antenna assembly.

[0005] In a first aspect, this application provides an antenna assembly including a first antenna and a second antenna. The second antenna includes a first portion, a second portion, and a hinged portion. The hinged portion is connected between the first portion and the second portion, and is hinged to the portion between the two ends of the first antenna, so that the antenna assembly has a folded state and an unfolded state. When the antenna assembly is in the folded state, the first portion and the second portion are in contact with the first antenna. When the antenna assembly is in the unfolded state, the end of the first portion away from the hinged portion is separated from the first antenna, and the end of the second portion away from the hinged portion is separated from the first antenna.

[0006] In this solution, since the hinged part is hinged to the two ends of the first antenna, the second antenna and the first antenna can rotate relative to each other. The relative rotation of the second antenna and the first antenna can put the antenna assembly in an unfolded state. The first antenna and the second antenna can search for wireless signals in specific directions, thereby improving the antenna assembly's ability to search for wireless signals and further improving the antenna performance of the antenna assembly.

[0007] In conjunction with the first aspect, in one possible implementation, the first antenna includes an omnidirectional antenna, and the second antenna includes at least one of an omnidirectional antenna and a directional antenna. The first antenna is capable of radiating and receiving radio signals omnidirectionally; when the second antenna includes an omnidirectional antenna, the second antenna is also capable of radiating and receiving radio signals omnidirectionally. Regardless of whether the antenna assembly is in a folded or unfolded state, the first and second antennas can radiate and receive radio signals omnidirectionally, respectively, thus providing gain to the antenna performance of the antenna assembly. When the second antenna includes a directional antenna, the second antenna can radiate and receive radio signals at a specific angle. When the antenna assembly is in an unfolded state, the second antenna can radiate and receive radio signals at a specific angle, thus providing gain to the antenna performance of the antenna assembly.

[0008] In conjunction with the first aspect, in one possible implementation, the first antenna includes a first surface and a second surface arranged opposite to each other. The first antenna passes through the second antenna. A first portion is located on the side of the first surface away from the second surface, and a second portion is located on the side of the second surface away from the first surface. The first portion and the second portion are located on the two opposite surfaces of the first antenna, such that the antenna assembly has an approximately X-shaped structure when deployed. This allows the first and second antennas to search for wireless signals in specific directions when deployed, thereby improving the antenna assembly's ability to search for wireless signals and thus enhancing its antenna performance.

[0009] In conjunction with the first aspect, in one possible implementation, the first antenna includes a connected third and fourth part. In the folded state, the third part contacts the first part, and the fourth part contacts the second part. In the unfolded state, the end of the first part away from the hinge and the end of the third part away from the fourth part respectively serve as supports for the antenna assembly; or, the end of the second part away from the hinge and the end of the fourth part away from the third part respectively serve as supports for the antenna assembly. This allows the antenna assembly to be stably placed in the unfolded state, thereby ensuring that the antenna assembly can stably maintain its unfolded state.

[0010] In conjunction with the first aspect, in one possible implementation, the hinged portion connects the first and second portions, forming an angle greater than 90° and less than 180° between the first and second portions, with the first and second portions parallel to each other. When the antenna assembly is folded, both the first and second portions are parallel to the first antenna. With both portions in contact with the first and second antennas in the folded state, the antenna assembly can have a roughly cubic structure, which is beneficial for its storage and portability.

[0011] In conjunction with the first aspect, in one possible implementation, the hinged portion includes two spaced-apart connecting ribs. Each connecting rib connects to a first part and a second part at both ends, respectively. The two connecting ribs, the first part, and the second part form a through slot through which the first antenna passes. Limiting slots are provided on opposite sides of the first antenna. The two connecting ribs are rotatably positioned within the two limiting slots, with the sidewall of each limiting slot movably abutting against the connecting rib it houses. By using the two limiting slots to limit the two connecting ribs of the second antenna, the maximum angle of rotation of the second antenna relative to the first antenna can be restricted. In the deployed state of the antenna assembly, the two limiting slots can limit the two connecting ribs, and the slot walls can support the two connecting ribs respectively. This allows the antenna assembly to remain stably deployed, i.e., the two limiting slots limit the two connecting ribs, enabling the antenna assembly to maintain a stable state in the deployed state and thus stably radiate or transmit wireless signals.

[0012] In conjunction with the first aspect, in one possible implementation, each limiting slot's sidewall includes a first sidewall and a second sidewall, the first and second sidewalls being located on opposite sides of the connecting rib housed in its respective limiting slot; the first sidewall includes an intersecting first segment and a second segment, the first segment and the second segment being used to movably abut against the first side surface of the connecting rib housed in its respective limiting slot; the first segment and the second segment form an angle greater than 0° and less than 180°, the opening of the angle formed by the first segment and the second segment facing away from the connecting rib housed in its respective limiting slot; the first segment is capable of movably contacting the connecting rib, the second segment is capable of movably contacting the connecting rib, when the first segment contacts the connecting rib, the second segment does not contact the connecting rib, when the second segment contacts the connecting rib, the first segment does not contact the connecting rib, the first segment and the second segment alternately contacting the connecting rib, enabling the antenna assembly to switch between a folded state and an unfolded state. The second sidewall includes intersecting third and fourth segments, which are used to movably abut against the second side of the connecting rib housed in their respective limiting slots. The third and fourth segments form an angle greater than 0° and less than 180°, with the opening of the angle between them facing away from the connecting rib housed in their respective limiting slots. The first and second side sides are arranged opposite to each other. The third and fourth segments can movably contact the connecting rib. When the third segment contacts the connecting rib, the fourth segment does not contact the connecting rib; when the fourth segment contacts the connecting rib, the third segment does not contact the connecting rib. The third and fourth segments alternately contact the connecting rib, enabling the antenna assembly to switch between folded and unfolded states.

[0013] In conjunction with the first aspect, in one possible implementation, the first side is parallel to the second side, the first segment is parallel to the third segment, and the second segment is parallel to the fourth segment. When the antenna assembly is in the folded state, the first side of the connecting rib contacts the first segment of its corresponding limiting groove, and the second side of the connecting rib contacts the third segment of its corresponding limiting groove. When the antenna assembly is in the unfolded state, the first side of the connecting rib contacts the second segment of its corresponding limiting groove, and the second side of the connecting rib contacts the fourth segment of its corresponding limiting groove. Because the first side is parallel to the second side, and the first segment is parallel to the third segment, the first side of the connecting rib can achieve surface-to-surface contact with the first segment of the limiting groove, and the second side of the connecting rib can achieve surface-to-surface contact with the third segment of the limiting groove. The first and second sides of the connecting rib can simultaneously make surface contact with the first and third segments of the limiting groove, respectively, which improves the stability of the antenna assembly in the folded state. Since the first side is parallel to the second side, and the second segment is parallel to the fourth segment, the first side of the connecting rib can make surface-to-surface contact with the second segment of the limiting groove, and the second side of the connecting rib can make surface-to-surface contact with the fourth segment of the limiting groove. The first side and the second side of the connecting rib can simultaneously make surface contact with the second segment and the fourth segment in the limiting groove, which can improve the stability of the antenna assembly in the folded state.

[0014] In conjunction with the first aspect, in one possible implementation, the first antenna includes a first housing, a first radiator, and a main board. The first radiator and the main board are disposed within the first housing. The main board is electrically connected to the first radiator and is used to power the first radiator. When the main board powers the first radiator, the first radiator is able to radiate or receive wireless signals.

[0015] In conjunction with the first aspect, in one possible implementation, the second antenna includes a second housing and a second radiator. The second radiator is disposed within the second housing and is electrically connected to a main board. The main board also powers the second radiator. A portion between the two ends of the second housing is hinged to a portion between the two ends of the first housing. When the main board powers the second radiator, the second radiator can radiate or receive wireless signals. The hinge between the two ends of the second housing and the portion between the two ends of the first housing allows the first and second housings to rotate relative to each other, thereby enabling relative rotation between the first and second antennas and further allowing the antenna assembly to have a folded state and an unfolded state.

[0016] In conjunction with the first aspect, in one possible implementation, the second radiator includes multiple sub-radiators with different directional radiation orientations. Each sub-radiator is electrically connected to a main board, which powers each sub-radiator. By incorporating multiple sub-radiators with different directional radiation orientations in the second antenna, the second antenna can have multiple different directional radiation directions, and the antenna assembly can select sub-radiators with different directional radiation orientations to radiate or transmit wireless signals.

[0017] In conjunction with the first aspect, in one possible implementation, the hinged portion further includes a pivot shaft that passes through the first housing and connects to the second housing. The first housing is hinged to the second housing via the pivot shaft. The first housing is rotatably connected to the second housing via the pivot shaft, allowing the first antenna and the second antenna to rotate relative to each other. This enables the antenna assembly to switch from a folded state to an unfolded state, and vice versa.

[0018] In conjunction with the first aspect, in one possible implementation, the second antenna also includes a feed line with a hollow hinge. The feed line passes through the hollow area of ​​the hinge to electrically connect to the main board and the second radiator. The hollow hinge protects the feed line, and by housing the feed line within the hollow hinge, the overall arrangement of the antenna assembly becomes neater, effectively utilizing the space of the hollow hinge and increasing the energy density of the antenna assembly.

[0019] Secondly, this application provides a mobile router, which includes an antenna assembly as described in the first aspect. Attached Figure Description

[0022] To more clearly illustrate the technical solutions in the embodiments or background art of this application, the application will be further described in detail below with reference to the accompanying drawings.

[0023] This application provides a mobile router that integrates an antenna assembly, a modem, and a Wireless Fidelity (Wi-Fi) module. It is capable of transmitting and receiving wireless signals, converting wireless signals, creating Wi-Fi networks, and assigning IP addresses. The mobile router also has an independent power supply and does not require constant mains power.

[0024] Mobile routers are often used in outdoor live streaming, emergency communications, and other scenarios. They can provide network support for terminal devices in areas with poor network signal.

[0025] The mobile router provided in this application includes an antenna assembly; please refer to [link / reference]. Figure 1 The antenna assembly 10 includes a first antenna 100 and a second antenna 200, one of the first antenna 100 and the second antenna 200 passing through the other. The portion between the two ends of the second antenna 200 is hinged to the portion between the two ends of the first antenna 100, so that the antenna assembly 10 has a folded state and an unfolded state.

[0026] For details, please see Figure 2The second antenna 200 includes a first part 210, a second part 220, and a hinged part 230. The hinged part 230 is connected between the first part 210 and the second part 220. The first part 210 is fixedly connected to the hinged part 230, and the second part 220 is fixedly connected to the hinged part 230. The hinged part 230 is hinged to the portion between the two ends of the first antenna 100. The hinged part 230 can rotate relative to the first antenna 100. When the hinged part 230 rotates, it causes the first part 210 and the second part 220 to rotate, so that the antenna assembly 10 can switch between a folded state and an unfolded state.

[0027] When the antenna assembly 10 is in the folded state, please refer to [the image / document]. Figure 3 When the antenna assembly 10 is in the folded state, the first antenna 100 and the second antenna 200 are close together, and the antenna assembly 10 is roughly cubic in shape. Among them, the first part 210 is in contact with the first antenna 100, and the second part 220 is in contact with the first antenna 100.

[0028] Please see Figure 4 When the antenna assembly 10 is in the unfolded state, the end of the first part 210 away from the hinge part 230 is separated from the first antenna 100, and the end of the second part 220 away from the hinge part 230 is also separated from the first antenna 100. By rotating the hinge part 230 relative to the first antenna 100, the antenna assembly 10 can be switched from a folded state to an unfolded state, or vice versa.

[0029] In this scheme, since the hinged part 230 is hinged to the part between the two ends of the first antenna 100, the second antenna 200 and the first antenna 100 can rotate relative to each other. The relative rotation of the second antenna 200 and the first antenna 100 can put the antenna assembly 10 in an unfolded state. The first antenna 100 and the second antenna 200 can search for wireless signals in specific directions, thereby improving the ability of the antenna assembly 10 to search for wireless signals and further improving the antenna performance of the antenna assembly 10.

[0030] In the embodiments provided in this application, the first antenna 100 includes a first surface 140 and a second surface 150 disposed opposite to each other. The first antenna 100 passes through the second antenna 200. A first portion 210 is located on the side of the first surface 140 away from the second surface 150, and a second portion 220 is located on the side of the second surface 150 away from the first surface 140. The first portion 210 and the second portion 220 are respectively located on the two opposite surfaces of the first antenna 100, so that the antenna assembly 10 has a roughly X-shaped structure when deployed. This allows the first antenna 100 and the second antenna 200 to search for wireless signals in specific directions when deployed, thereby improving the ability of the antenna assembly 10 to search for wireless signals and thus improving the antenna performance of the antenna assembly 10.

[0031] Please see Figure 3 The first antenna 100 includes a third part 100a and a fourth part 100b connected together. When the antenna assembly 10 is in a folded state, the third part 100a is in contact with the first part 210, and the fourth part 100b is in contact with the second part 220.

[0032] Please see Figure 4 When the antenna assembly 10 is in the unfolded state, the end of the first part 210 away from the hinge part 230 and the end of the third part 100a away from the fourth part 100b respectively serve as the support legs of the antenna assembly 10; or, the end of the second part 220 away from the hinge part 230 and the end of the fourth part 100b away from the third part 100a respectively serve as the support legs of the antenna assembly 10, so that the antenna assembly 10 can be stably placed in the unfolded state, thereby enabling the antenna assembly 10 to be stably maintained in the unfolded state.

[0033] In the antenna assembly 10 provided in this application, the first antenna 100 includes an omnidirectional antenna, and the second antenna 200 includes at least one of an omnidirectional antenna and a directional antenna.

[0034] The first antenna 100 can radiate and receive wireless signals in all directions; when the second antenna 200 includes an omnidirectional antenna, the second antenna 200 can also radiate and receive wireless signals in all directions. Regardless of whether the antenna assembly 10 is in a folded or unfolded state, the first antenna 100 and the second antenna 200 can radiate and receive wireless signals in all directions respectively, which can bring gain to the antenna performance of the antenna assembly 10.

[0035] When the second antenna 200 includes a directional antenna, the second antenna 200 can radiate and receive wireless signals at a specific angle. When the antenna assembly 10 is in the deployed state, the second antenna 200 can radiate and receive wireless signals at a specific angle, which can bring gain to the antenna performance of the antenna assembly 10.

[0036] Please refer to the embodiments provided in this application. Figure 4 The antenna assembly 10 is in the deployed state, and the angle α formed by the first antenna 100 and the second antenna 200 is greater than 0° and less than or equal to 159°.

[0037] In the embodiments provided in this application, when the second antenna 200 includes a directional antenna, the angle formed by the first antenna 100 and the second antenna 200 is set according to the directional angle of the second antenna 200. In most cases, the antenna assembly 10 interacts with the base station 600 to transmit and receive signals. The direction of the antenna assembly 10 and the base station 600 transmitting and receiving signals is mostly above the horizontal plane, so that the angle α formed by the first antenna 100 and the second antenna 200 is greater than 0° and less than or equal to 159°. In the deployed state, the antenna assembly 10 can adapt to most scenarios to interact with the base station 600 to transmit and receive signals.

[0038] In some embodiments, the antenna assembly 10 is in an extended state, with the second antenna 200 forming an angle of 30°-60° with the vertical direction. The antenna assembly 10 interacts with the base station 600 wirelessly in most cases, and the direction of signal transmission and reception between the antenna assembly 10 and the base station 600 is mostly diagonally above the horizontal plane, resulting in an angle of 30°-60° between the second antenna 200 and the vertical direction. In its extended state, the antenna assembly 10 can adapt to most scenarios for interacting with the base station 600 wirelessly.

[0039] When the second antenna 200 includes a directional antenna, the second antenna 200 can directionally interact with the base station 600 to exchange wireless signals. For example, the angle between the directional direction of the second antenna 200 and the vertical direction is 30°, and the angle between the first antenna 100 and the second antenna 200 can be set to 60°. In this case, when the antenna assembly 10 is placed on a horizontal plane, one end of the first antenna 100 and one end of the second antenna 200 both serve as supports, allowing the antenna assembly 10 to be stably placed on the horizontal plane in its deployed state. This ensures that the direction in which the second antenna 200 radiates or receives wireless signals is at an angle of 30° to the vertical direction, enabling the second antenna 200 to perform directional radiation and reception of wireless signals, thus improving the antenna performance of the antenna assembly 10.

[0040] Please see Figure 4 The hinge portion 230 is connected between the first portion 210 and the second portion 220. The first portion 210 and the hinge portion 230 form an angle β greater than 90° and less than 180°. The first portion 210 is parallel to the second portion 220. When the antenna assembly 10 is in the folded state, the first part 210 is parallel to the first surface 140, and the second part 220 is parallel to the second surface 150.

[0041] In the embodiments provided in this application, when the antenna assembly 10 is in the unfolded state, the first antenna 100 and the second antenna 200 form an X-shaped structure. To make the antenna assembly 10 more organized and easier to carry when folded, the first portion 210 is parallel to the first surface 140 and the second portion 220 is parallel to the second surface 150 when the antenna assembly 10 is folded, which makes the antenna assembly 10 approximately cubic in structure. The first portion 210 and the second portion 220 are located on the first surface 140 and the second surface 150, respectively, which are opposite to the first antenna 100. When the antenna assembly 10 is folded, the first portion 210 and the second portion 220 are in contact with the first antenna 100, which makes the antenna assembly 10 approximately cubic in structure, facilitating its storage and carrying.

[0042] Please see Figure 5 The hinge portion 230 includes two spaced connecting ribs 231. The two ends of each connecting rib 231 are connected to the first portion 210 and the second portion 220, respectively. The two connecting ribs 231, the first portion 210 and the second portion 220 form a through slot through which the first antenna 100 passes. The first antenna 100 is provided with limiting slots 111 on opposite sides. The two connecting ribs 231 are rotatably disposed in the two limiting slots 111, and the sidewall of each limiting slot 111 is in movable contact with the connecting rib 231 it accommodates.

[0043] Limiting grooves 111 are provided on two opposite sides of the first antenna 100. The two limiting grooves 111 limit the two connecting ribs 231 of the second antenna 200, which can limit the maximum angle of rotation of the second antenna 200 relative to the first antenna 100. When the antenna assembly 10 is in the unfolded state, the two limiting grooves 111 can limit the two connecting ribs 231. The groove walls of the two limiting grooves 111 can support the two connecting ribs 231 respectively, so that the antenna assembly 10 can be stably in the unfolded state. That is, the two limiting grooves 111 limit the two connecting ribs 231 respectively, so that the antenna assembly 10 can maintain a stable state in the unfolded state, and the antenna assembly 10 can stably radiate or transmit wireless signals.

[0044] Each limiting groove 111 has a sidewall including a first sidewall 111a and a second sidewall 111d. The first sidewall 111a and the second sidewall 111d are arranged opposite to each other. The first sidewall 111a and the second sidewall 111d are located on both sides of the connecting rib 231 contained in the limiting groove 111 to which they belong. The first sidewall 111a includes an intersecting first segment 111b and a second segment 111c. The first segment 111b and the second segment 111c are used to movably abut against the first side surface 231a of the connecting rib 231 received by the corresponding limiting groove 111. The first segment 111b and the second segment 111c form an angle γ greater than 0° and less than 180°. The opening of the angle formed by the first segment 111b and the second segment 111c faces away from the connecting rib 231 received by the corresponding limiting groove 111. The first segment 111b can make movable contact with the connecting rib 231, and the second segment 111c can make movable contact with the connecting rib 231. When the first segment 111b is in contact with the connecting rib 231, the second segment 111c is not in contact with the connecting rib 231. When the second segment 111c is in contact with the connecting rib 231, the first segment 111b is not in contact with the connecting rib 231. The first segment 111b and the second segment 111c alternately contact the connecting rib 231, which enables the antenna assembly 10 to switch between folded and unfolded states.

[0045] The second sidewall 111d includes intersecting third segment 111e and fourth segment 111f. The third segment 111e and the fourth segment 111f are used to movably abut against the second side surface 231b of the connecting rib 231 received by the corresponding limiting groove 111. The third segment 111e and the fourth segment 111f form an angle γ greater than 0° and less than 180°. The opening of the angle formed by the third segment 111e and the fourth segment 111f faces away from the connecting rib 231 received by the corresponding limiting groove 111. The first side surface 231a and the second side surface 231b are arranged opposite to each other.

[0046] The third segment 111e can make movable contact with the connecting rib 231, and the fourth segment 111f can make movable contact with the connecting rib 231. When the third segment 111e is in contact with the connecting rib 231, the fourth segment 111f is not in contact with the connecting rib 231. When the fourth segment 111f is in contact with the connecting rib 231, the third segment 111e is not in contact with the connecting rib 231. The third segment 111e and the fourth segment 111f alternately contact the connecting rib 231, which enables the antenna assembly 10 to switch between folded and unfolded states.

[0047] In the embodiments provided in this application, the angle formed by the first segment 111b and the second segment 111c is equal to the angle formed by the third segment 111e and the fourth segment 111f. The angle formed by the first segment 111b and the second segment 111c is complementary to the maximum angle of rotation of the second antenna 200 relative to the first antenna 100. The angle formed by the third segment 111e and the fourth segment 111f is complementary to the maximum angle of rotation of the second antenna 200 relative to the first antenna 100.

[0048] The first side 231a is parallel to the second side 231b, the first segment 111b is parallel to the third segment 111e, and the second segment 111c is parallel to the fourth segment 111f.

[0049] When the antenna assembly 10 is in the folded state, the first side 231a of the connecting rib 231 contacts the first segment 111b of the limiting groove 111 in which it is located, and the second side 231b of the connecting rib 231 contacts the third segment 111e of the limiting groove 111 in which it is located. Since the first side 231a is parallel to the second side 231b, and the first segment 111b is parallel to the third segment 111e, the first side 231a of the connecting rib 231 and the first segment 111b of the limiting groove 111 can achieve surface-to-surface contact, and the second side 231b of the connecting rib 231 and the third segment 111e of the limiting groove 111 can achieve surface-to-surface contact. The first side 231a and the second side 231b of the connecting rib 231 can simultaneously make surface contact with the first segment 111b and the third segment 111e in the limiting groove 111, respectively, which can improve the stability of the antenna assembly 10 in the folded state.

[0050] When the antenna assembly 10 is in the unfolded state, the first side 231a of the connecting rib 231 contacts the second segment 111c of the limiting groove 111 in which it is located, and the second side 231b of the connecting rib 231 contacts the fourth segment 111f of the limiting groove 111 in which it is located.

[0051] Since the first side 231a is parallel to the second side 231b, and the second segment 111c is parallel to the fourth segment 111f, the first side 231a of the connecting rib 231 and the second segment 111c of the limiting groove 111 can achieve surface-to-surface contact, and the second side 231b of the connecting rib 231 and the fourth segment 111f of the limiting groove 111 can achieve surface-to-surface contact.

[0052] Please refer to the embodiments provided in this application. Figure 6 The first antenna 100 includes a first housing 110, a first radiator 120 and a main board 130. The first radiator 120 and the main board 130 are disposed inside the first housing 110. The main board 130 is electrically connected to the first radiator 120 and is used to feed power to the first radiator 120.

[0053] In some embodiments, the first housing 110 may house the first radiator 120, and the first radiator 120 may also be part of the first housing 110. When the motherboard 130 powers the first radiator 120, the first radiator 120 can radiate or receive wireless signals. In some embodiments, the first radiator 120 may be a metal plate, and the outer surface of the metal plate may be provided with a metasurface to improve the antenna performance of the first radiator 120.

[0054] The motherboard 130 can be housed within the first housing 110, which protects the motherboard 130 from dust accumulation and prevents it from negatively impacting the antenna performance of the antenna assembly 10.

[0055] Please see Figure 7 The second antenna 200 includes a second housing 240 and a second radiator 250. The second radiator 250 is disposed inside the second housing 240 and is electrically connected to the main board 130. The main board 130 is also used to power the second radiator 250. The portion between the two ends of the second housing 240 is hinged to the portion between the two ends of the first housing 110.

[0056] The second housing 240 can accommodate the second radiator 250, and the second radiator 250 can also be part of the second housing 240. When the motherboard 130 powers the second radiator 250, the second radiator 250 can radiate or receive wireless signals. The second radiator 250 can be a metal plate, and the outer surface of the metal plate can be provided with a metasurface to improve the antenna performance of the first radiator 120.

[0057] In the antenna assembly 10 provided in this application, see also Figure 7 The hinge portion 230 also includes a pivot 260, which passes through the first housing 110 and connects to the second housing 240. The first housing 110 is hinged to the second housing 240 via the pivot 260. The first housing 110 is rotatably connected to the second housing 240 via the pivot 260, allowing the first antenna 100 and the second antenna 200 to rotate relative to each other. This enables the antenna assembly 10 to switch from a folded state to an unfolded state, and vice versa.

[0058] In the embodiments provided in this application, the second antenna 200 further includes a feed line 270, and a hollow hinge 260. The hollow area of ​​the hinge 260 allows the feed line 270 to extend into it. The feed line 270 passes through the hollow area of ​​the hinge 260 to electrically connect to the main board 130 and the second radiator 250. The hollow hinge 260 can protect the feed line 270. By using the hollow hinge 260 to house the feed line 270, the overall arrangement of the antenna assembly 10 can be made neater, and the space of the hollow hinge 260 can be effectively utilized to improve the energy density of the antenna assembly 10.

[0059] In the embodiments provided in this application, the second radiator 250 may include a plurality of sub-radiators with different directional radiation orientations, each of which is electrically connected to the main board 130, and the main board 130 is used to power each sub-radiator.

[0060] By setting multiple sub-radiators with different directional radiation directions in the second antenna 200, the second antenna 200 can have multiple different directional radiation directions, and the antenna assembly 10 can select sub-radiators with different directional radiation directions to radiate or transmit wireless signals.

[0061] For example, multiple sub-radiators with different directional radiation directions include forward sub-radiators, backward sub-radiators, and lateral sub-radiators. The main board 130 can feed the forward, backward, and lateral sub-radiators. During the selection of sub-radiators, the second antenna 200 can select based on the strength of the wireless signal in different directions. If the forward wireless signal strength is high, the antenna assembly 10 can select a forward sub-radiator to radiate or receive the wireless signal. If the backward wireless signal strength is high, the antenna assembly 10 can select a backward sub-radiator to radiate or receive the wireless signal. If the lateral wireless signal strength is high, the antenna assembly 10 can select a lateral sub-radiator to radiate or receive the wireless signal. It is understandable that when the antenna assembly is stationary in a certain area, the antenna assembly 10 can select sub-radiators to radiate or receive the wireless signal based on the strength of the wireless signal in different directions within that area (e.g., mountainous areas, airports, hotels, etc.). The signal strength in different directions within the area where the antenna assembly is located may vary. The antenna assembly 10 can switch between different sub-radiators to radiate or receive wireless signals based on these varying signal strengths. For example, in the first time period, if the forward wireless signal in the area where the antenna assembly 10 is located is strong, the antenna assembly 10 can select a forward sub-radiator to radiate or receive wireless signals. In the second time period, if the backward wireless signal in the area where the antenna assembly 10 is located is strong, the antenna assembly 10 can select a backward sub-radiator to radiate or receive wireless signals. In the third time period, if the lateral wireless signal in the area where the antenna assembly is located is strong, the antenna assembly 10 can select a lateral sub-radiator to radiate or receive wireless signals.

[0062] In some embodiments, the antenna assembly 10 is movable, for example, located on a high-speed train or vehicle. The antenna assembly 10 moves with the train or vehicle, meaning the area where the antenna assembly 10 is located is constantly changing, and the strength of the wireless signal varies in different areas. The direction in which the wireless signal is strongest may also change. The antenna assembly 10 switches its sub-radiator based on the different directional signals in its area. In a first area, where the front wireless signal strength is higher, the antenna assembly 10 can limit the front radiator from radiating or receiving signals. When the antenna assembly 10 moves from the first area to a second area, where the rear wireless signal strength is higher, the antenna assembly 10 can switch the front radiator from radiating or receiving wireless signals to a rear sub-radiator.

[0063] In some embodiments, the antenna assembly 10 may also select multiple sub-radiators for coordinated radiation or reception, thereby improving the antenna performance of the antenna assembly 10 and reducing the likelihood of video stuttering when the antenna assembly 10 allocates network access to the terminal device.

[0064] Please refer to the embodiments provided in this application. Figure 8 and Figure 9 The first part 210 may contain forward sub-radiators 255, backward sub-radiators 256, lateral sub-radiators 257, first omnidirectional sub-radiators 251 and second omnidirectional sub-radiators 252, and the second part 220 may contain forward sub-radiators 258, backward sub-radiators 259, lateral sub-radiators 259a, third omnidirectional sub-radiators 253 and fourth omnidirectional sub-radiators 254.

The first transceiver 300 may select one of the four sub-radiators to be electrically connected to the radio frequency front-end module 500. The second omnidirectional sub-radiator 252 is electrically connected to the RF front-end module 500. The RF front-end module 500 can simultaneously communicate with two or more radiators. For example, in addition to communicating with one of the forward sub-radiators, backward sub-radiators, lateral sub-radiators, and the first omnidirectional sub-radiator 251 in the first part 210, the RF front-end module 500 can also simultaneously communicate with the second omnidirectional sub-radiator 252. The two or more sub-radiators cooperate to radiate or receive wireless signals, realizing the multiple-input multiple-output (MIMO) function of the antenna assembly 10, which can improve the antenna performance of the antenna assembly 10. The RF front-end module 500 can receive signals from the second omnidirectional sub-radiator 252 discontinuously (DRX), reducing the power consumption of the antenna assembly 10 and thus improving the battery life of the antenna assembly 10.

[0067] The antenna assembly 10 may also include a second transceiver 400. The forward sub-radiator 258, the backward sub-radiator 259, the lateral sub-radiator 259a, and the third omnidirectional sub-radiator 253 in the second part 220 can be electrically connected to the radio frequency front-end module 500 through the second transceiver 400. The second transceiver 400 may select one of the four sub-radiators to be electrically connected to the radio frequency front-end module 500. The fourth omnidirectional sub-radiator 254 is electrically connected to the RF front-end module 500. The RF front-end module 500 can simultaneously communicate with two or more radiators. For example, in addition to communicating with one of the forward sub-radiators 258, backward sub-radiators 259, lateral sub-radiators 259a, and the third omnidirectional sub-radiator 253 in the second part 220, the RF front-end module 500 can also simultaneously communicate with the fourth omnidirectional sub-radiator 254. The two or more sub-radiators cooperate to radiate or receive wireless signals, realizing the multiple-input multiple-output (MIMO) function of the antenna assembly 10, which can improve the antenna performance of the antenna assembly 10. The RF front-end module 500 can receive signals from the fourth omnidirectional sub-radiator 254 discontinuously, reducing the power consumption of the antenna assembly 10 and thus improving the battery life of the antenna assembly 10.

Figure 10 and Figure 11Since the RF front-end module 500 can selectively communicate with each sub-radiator in the first part 210 and each sub-radiator in the second part 220, the antenna assembly 10 has a variety of different combinations of sub-radiators cooperating in radiating or receiving wireless signals. For example, the first omnidirectional sub-radiator 251 in the first part 210 and the third omnidirectional sub-radiator 253 in the second part 220 can cooperate in radiating or receiving wireless signals; the forward sub-radiator in the first part 210 and the forward sub-radiator in the second part 220 can cooperate in radiating or receiving wireless signals; the forward sub-radiator in the first part 210 and the backward sub-radiator in the second part 220 can cooperate in radiating or receiving wireless signals; the forward sub-radiator in the first part 210 and the lateral sub-radiator in the second part 220 can cooperate in radiating or receiving wireless signals; the backward sub-radiator in the first part 210 and the...
