Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without any inventive effort, are intended to be within the scope of the application.

Reference herein to "an embodiment" or "implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment or implementation may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, the present application provides a ue 200, where the ue 200 (Customer Premises Equipment, CPE) is a network switching device commonly used for indoor/near field communication, or a signal access device that receives signals and forwards them as wireless signals. As shown in fig. 1, the ue 200 communicates with the base station 100, receives a first network signal sent by the base station 100, and converts the first network signal into a second network signal. The second network signal may be used by the smart device 300 such as a mobile phone, a tablet computer, a notebook computer, etc. Wherein the first network signal may be, but is not limited to being, a fifth generation mobile communication technology (5th generation mobile networks,5G) signal and the second network signal may be, but is not limited to being, a wireless fidelity technology (Wireless Fidelity, wiFi) signal. The user terminal device 200 can be applied to rural areas, towns, hospitals, factories, cells and the like in large numbers.

Referring to fig. 2 and 3, the ue 200 of the present application includes a main board 20 and an antenna module 10 described in any embodiment below, wherein the main board 20 is electrically connected to the antenna module 10. The main board 20 is a circuit board (Printed Circuit Board, PCB), and the main board 20 is used for controlling the antenna module 10. The user terminal device 200 may further include a housing 30, where the housing 30 is configured to house the antenna module 10, the motherboard 20, and the like. The shape of the housing 30 may be a cylinder, a prism, a rectangular body, etc. The material of the housing 30 may be, but is not limited to, a non-electromagnetic wave shielding material. It will be appreciated that in other embodiments, the user terminal device 200 may not include the housing 30.

Further, the first network signal may be, but is not limited to being, a millimeter wave signal. Currently, in the fifth generation mobile communication technology (5th generation wireless systems,5G), the 5G new air interface (NR) mainly uses two frequencies according to the specification of the 3gpp TS 38.101 protocol: FR1 band and FR2 band. Wherein the frequency range of the FR1 frequency band is 450 MHz-6 GHz, which is also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, belonging to the millimeter Wave (mm Wave) frequency band. The 3GPP Release 15 Release has standardized the current 5G millimeter wave band to include: n257 (26.5-29.5 GHz), n258 (24.25-27.5 GHz), n261 (27.5-28.35 GHz) and n260 (37-40 GHz). Millimeter wave signals have advantages such as high transmission speed, however, millimeter wave signals are easily shielded by external objects. When an object is blocked between the antenna module 10 and the base station 100, the signal strength of the first network signal received by the antenna module 10 is weak, and at this time, if the first network signal with weak signal strength is converted into the second network signal, the signal strength of the obtained second network signal may be also weak. Therefore, to obtain a higher signal strength, the antenna module 10 needs to be changed, which will be described in detail with reference to the accompanying drawings.

Referring to fig. 4 to 8, the present application provides an antenna module 10, the antenna module 10 includes: a first wire spool 110, an antenna assembly 120, and a first cable 130. Wherein the antenna assembly 120 is rotatable relative to the first wire spool 110. The first cable 130 is used for connecting the antenna assembly 120 and the motherboard 20. During rotation of the antenna assembly 120, the first cable 130 will follow the outer circumference of the first wire coil 110 under traction of the antenna assembly 120 (as shown in fig. 6). The first cable 130 includes a plurality of first sub-cables 131. The plurality of first sub-cables 131 are arranged side by side so that bending radii are uniform (as shown in fig. 6 to 8).

Specifically, the antenna assembly 120 is configured to receive and transmit signals. The antenna assembly 120 may be rotated to achieve an optimal orientation of signal strength. The first cable 130 is used for electrically connecting the antenna assembly 120 and the motherboard 20, so that communication between the antenna assembly 120 and the motherboard 20 is possible. The motherboard 20 is generally fixed, and when the antenna assembly 120 rotates, the first cable 130 is pulled by the antenna assembly 120 to move, and the position and shape of the first cable 130 are changed accordingly, which may cause damage to the first cable 130 or other components if the first cable 130 is not limited. In this embodiment, the first wire coil 110 is used to limit the movement and shape of the first cable 130, that is, the first wire coil 110 can block the movement of the first cable 130, so that the antenna assembly 120 bends around the outer periphery of the first wire coil 110 in the process of pulling the first cable 130 to move. In addition, the first cable 130 includes a plurality of first sub-cables 131, and the number of the first sub-cables 131 may be, but is not limited to, 2, 4, 6, etc., and the present application is exemplified by 4. All the first sub-cables 131 are arranged side by side, which means that all the first sub-cables 131 are arranged in a straight line (as shown in fig. 8), so that when the first cables 130 are bent in conformity with the shape of the first wire coil 110, all the first sub-cables 131 can achieve the same bending radius. The first sub-cable 131 may also be referred to as a coaxial cable (RF coaxial cable), where the coaxial cable has two concentric conductors, and the conductor and the shielding layer share the same axis.

Note that, the first cable 130 is compliant with the outer circumferential curvature of the first wire coil 110 means that: the first cable 130 abuts against the first wire coil 110 and bends along the outer profile of the first wire coil 110. Thus, the curved shape of the first cable 130 and the outer contour shape of the first wire coil 110 are adapted, for example, the outer contour of the first wire coil 110 is a cylindrical surface, and the curved shape of the first cable 130 is an arc.

Optionally, the first coil 110 is spaced from the antenna assembly 120, so that friction between the two is avoided, thereby facilitating the rotation of the antenna assembly 120.

In the related art, the first sub-cables 131 in the first cable 130 are not arranged in a straight line. For example, when the number of the first sub-cables 131 is 4, the 4 first sub-cables 131 may be placed in a delta-shaped manner (as shown in fig. 9); when the number of the first sub-cables 131 is 6, 6 first sub-cables 131 may be placed in a circular manner (as shown in fig. 10). However, when the first cable 130 is bent, the first sub-cable 131 must have an inner-outer portion, that is, a portion of the first sub-cable 131 is located at the outer side of the bent portion and a portion of the first sub-cable 131 is located at the inner side of the bent portion, regardless of the above-mentioned delta-shaped or circular arrangement. The first sub-cable 131 on the outer side has a larger bending radius and a longer circumference than the first sub-cable 131 on the inner side, and is pulled to have different stress values, so that the service life of the first cable 130 is shortened. Meanwhile, the above arrangement also increases the bending stress of the first cable 130, and thus increases the driving load, resulting in an increase in power consumption. In addition, in order to reduce the bending stress of the above arrangement, a smaller wire diameter gauge (for example, a wire diameter gauge of 0.64 mm) is generally adopted for the first sub-cable 131, and the smaller wire diameter gauge means that the wire loss is larger, thereby impairing the transmission efficiency.

Compared with the related art, the plurality of first sub-cables 131 in the first cable 130 are arranged in parallel, when the first cable 130 is bent in conformity with the shape of the first wire coil 110, the first sub-cables 131 do not have inner and outer parts, that is, all the first sub-cables 131 can achieve the same bending radius during bending, so that the bending stress of the first sub-cables 131 is uniform, thereby prolonging the service life of the first cable 130, and simultaneously reducing the driving load and reducing the power consumption. In addition, because the overall bending stress of the parallel arrangement is smaller, the first sub-cable 131 can use a larger wire diameter (for example, the first sub-cable 131 uses a wire diameter of 0.81 mm), and the larger the wire diameter, the smaller the resistance, the less the loss and the higher the transmission efficiency.

It should be noted that, in one embodiment, the plurality of first sub-cables 131 side by side may be adhered together by glue. In another embodiment, referring to fig. 11, the first cable 130 further includes a wrapping layer 132, where the wrapping layer 132 wraps the plurality of first sub-cables 131 side by side. Of course, the plurality of first sub-cables 131 may also be secured together by other means, such as by using wire management clips, which are not described in detail herein for other possible embodiments.

Referring to fig. 4 and 5, the antenna assembly 120 includes a heat spreader 121, a die 122, and a chip 123. The heat sink 121 has adjacent first and second sides D1 and D2. The chip 123 is electrically connected to the small board 122. The platelet 122 is fixed to the first side D1. The first wire coil 110 is disposed on the second side D2. The relative direction of the first wire coil 110 and the heat sink 121 is a preset direction. The heat sink 121 may rotate around the preset direction.

Wherein the small board 122 is a circuit board (Printed Circuit Board, PCB) electrically connected to the first cable 130. The small plate 122 is fixed to the first side D1 of the heat spreader 121, and the fixing manner thereof may be, but not limited to, connection by a fastening, bonding, or a connection by a bolt. The chip 123 is mounted on the side of the platelet 122 facing away from the heat sink 121. The chip 123 may also be referred to as an antenna, which is used for receiving and transmitting signals. The chip 123 is communicatively connected to the motherboard 20 via a first cable 130. The chip 123 will generate heat during operation, and the heat sink 121 is used for dissipating heat from the chip 123. Since the first wire coil 110 is disposed at the second side D2 adjacent to the first side D1, when the heat sink 121 rotates around the preset direction, the chip 123 may be changed in orientation, thereby obtaining a position where the signal is optimal.

It should be noted that the number of chips 123 may be, but is not limited to, 1, 3, 4, 6, etc., and the present application is exemplified by only 4. Here, two coaxial lines are required for 1 chip 123, 8 coaxial lines are required for 4 chips 123, in other words, if the chips 123 are communicatively connected to the motherboard 20 only through the first cables 130, 8 first sub-cables 131 are required.

Referring to fig. 4 and 5, the antenna module 10 further includes a motor 160. The motor 160 is connected to the antenna assembly 120, and is used for driving the antenna assembly 120 to rotate.

Referring to fig. 3 in conjunction with fig. 4, the main board 20 and the first wire coil 110 are disposed on the same side of the antenna assembly 120, in other words, the main board 20 and the first wire coil 110 are disposed on the second side D2. The following describes advantages of this design form with respect to the related art.

In the related art, the first wire coil 110 and the main board 20 are disposed on two opposite sides of the antenna assembly 120, and the chip 123 is disposed therebetween. Since the first cable 130 is used to electrically connect the chip 123 and the main board 20 and tensioning is required by the first wire reel 110, at least part of the first cable 130 needs to traverse from the first wire reel 110 to the main board 20. When the chip 123 just rotates to face the first cable 130, the first cable 130 shields the chip 123, thereby affecting the reception of signals by the chip 123, and the length of the first cable 130 is increased, resulting in larger line loss and reduced reception power.

In comparison with the related art described above, in the present embodiment, the main board 20 and the first wire coil 110 are disposed on the same side of the antenna assembly 120, so that the first cable 130 is prevented from shielding the chip 123 and the length of the first cable 130 is shortened.

Referring to fig. 12 to 16, the first wire coil 110 includes a first main body 111, a first middle 112, and a first offset 113 (see fig. 13). The first middle portion 112 and the first offset portion 113 are protruded on the same side of the first body portion 111. At least a portion of the first cable 130 is disposed between the first intermediate portion 112 and the first offset portion 113. Referring to fig. 16 in conjunction with fig. 14, after the antenna assembly 120 rotates in the first direction F1, the first cable 130 follows the outer circumference of the first middle portion 112. Referring to fig. 14 in conjunction with fig. 16, after the antenna assembly 120 rotates in the second direction F2, the first cable 130 follows the outer circumference of the first offset portion 113. Wherein the first direction F1 and the second direction F2 are opposite.

In other words, the first intermediate portion 112 of the first wire coil 110 and the first offset portion 113 are spaced apart to form a first gap, and the first cable 130 passes through the first gap such that at least a portion of the first cable 130 is located between the first intermediate portion 112 and the first offset portion 113, and thus, when the antenna assembly 120 moves in the first direction F1 or the second direction F2, the first cable 130 will be wound around the outer circumference of the first intermediate portion 112 or the first offset portion 113.

Specifically, the antenna module 10 has a first state and a second state. When the antenna module 10 is in the first state, the first cable 130 surrounds the outer periphery of the first offset portion 113 (as shown in fig. 14). When the antenna module 10 is switched from the first state to the second state, the antenna assembly 120 rotates in the first direction F1, the first cable 130 gradually breaks away from the first biasing portion 113, and the first cable 130 gradually follows the outer circumference of the first middle portion 112 (as shown in fig. 15). When the antenna module 10 is in the second state, the first cable 130 surrounds the outer periphery of the first middle portion 112 (as shown in fig. 16). When the antenna module 10 is switched from the second state to the first state, the antenna assembly 120 rotates in the second direction F2, the first cable 130 gradually breaks away from the first middle portion 112, and the first cable 130 gradually bends along the outer circumference of the first biasing portion 113 until being switched to the first state.

In the related art, only the first intermediate portion 112 is generally provided, and the first offset portion 113 is not provided. When the antenna assembly 120 rotates in the first direction F1, the first cable 130 is wound around the first middle portion 112. When the antenna assembly 120 rotates in the second direction F2, the first cable 130 is released. However, the first cable 130 is in a loose state when being released, and the first cable 130 in this state is likely to be wound around other components due to external shake, and when the first cable 130 is again tightened, the wound components may be damaged, so that the antenna module 10 cannot work normally.

Compared to the above-mentioned related art that only the first cable 130 can be tightened in one rotation direction, in the present embodiment, since the first middle portion 112 and the first offset portion 113 are provided at the same time, the tightening of the first cable 130 can be achieved regardless of whether the antenna assembly 120 rotates in the first direction F1 or rotates in the second direction F2, i.e., the antenna assembly 120 can tighten the first cable 130 in two rotation directions, so that the possibility of damaging other components can be reduced.

Referring to fig. 17 in conjunction with fig. 12, the antenna module 10 further includes a second wire coil 140 and a second cable 150. The second wire coil 140 is fixedly connected to the first wire coil 110, and the fixed connection may be detachable connection or non-detachable connection. The second cable 150 is connected to the antenna assembly 120. During rotation of the antenna assembly 120, the second cable 150 will flex under traction of the antenna assembly 120 against the outer circumference of the second wire coil 140.

The second cable 150, which has the same function as the first cable 130, is also used to electrically connect the antenna assembly 120 and the motherboard 20, so that communication between the chip 123 and the motherboard 20 is possible. The second wire coil 140 is used to limit the movement and shape of the second cable 150, that is, the second wire coil 140 may block the movement of the second cable 150, so that the second cable 150 may bend around the outer circumference of the second wire coil 140 in the course of pulling the second cable 150 to move by the antenna assembly 120. In addition, the second cable 150 includes a plurality of second sub-cables 151 (as shown in fig. 18), and the number of the second sub-cables 151 may be, but is not limited to, 2, 4, 6, etc., and the present application is exemplified by 4. All the second sub-cables 151 are arranged side by side, which means that all the second sub-cables 151 are arranged in a straight line, and thus, when the second cables 150 are bent in conformity with the shape of the second wire coil 140, all the second sub-cables 151 can achieve the same bending radius. The second sub-cable 151 may also be referred to as a coaxial cable (RF coaxial cable), and the wire diameter of the second sub-cable 151 may be the same as the wire diameter of the first sub-cable 131.

The function of providing the second cable 150 on the basis of the first cable 130 is described below in connection with the antenna assembly 120: generally, after the position of the chip 123 is determined, the connection position of the coaxial line to the board 122 will also be determined (hereinafter, the connection position of the coaxial line to the board 122 will be referred to as a connection point). Because of the distance between the different connection points, if the second cable 150 is incorporated into the first cable 130 (i.e. only the first cable 130 is present and no second cable 150 is present), the lengths of the first sub-cables 131 are not uniform, thereby affecting the performance of the antenna module 10. In this embodiment, the second cable 150 is independent of the first cable 130, so that the connection point corresponding to the first cable 130 and the connection point corresponding to the second cable 150 can be symmetrically arranged, and after the symmetrical arrangement, the corresponding first sub-cable 131 and second sub-cable 151 can be set to be the same or similar length, thereby reducing the line loss gap, and further being beneficial to improving the performance of the antenna module 10. In addition, the first cable 130 and the second cable 150 are independently arranged, which is also beneficial to making the stress of the coaxial line more symmetrical and uniform, so that the service life of the antenna module 10 can be prolonged.

Alternatively, referring to fig. 19, the antenna module 10 is a 4mm wave chip 123 structure, i.e. the number of chips 123 is 4. In one embodiment, all 4 chips 123 are communicatively coupled to motherboard 20 via a first cable 130. In another embodiment, a portion of the chips 123 are communicatively coupled to the motherboard 20 via a first cable 130, and another portion of the chips 123 are communicatively coupled to the motherboard 20 via a second cable 150.

Optionally, the number of the first sub-cables 131 and the second sub-cables 151 is the same and is 4. Since each chip 123 needs to be connected to the motherboard 20 through two coaxial lines, the 4 first sub-cables 131 can realize 2 chips 123 to be connected to the motherboard 20 through communication, and the 4 second sub-cables 151 can also realize another 2 chips 123 to be connected to the motherboard 20 through communication.

In the related art, since only the first cable 130 is provided and the excessive thickness in which the first cable 130 cannot be designed is considered, a 2 mm-wave chip 123 architecture is generally employed. Compared with the related art, the present application provides the achievable condition for the 4 millimeter wave chip 123 architecture by independently arranging the first cable 130 and the second cable 150. It can be understood that the greater the number of chips 123, the greater the bandwidth, and the better the signal transceiving effect.

Referring to fig. 20 to 23, the second wire coil 140 includes a second main body 141, a second middle 142, and a second offset 143. The second intermediate portion 142 and the second offset portion 143 are protruded from a side of the second body portion 141 facing the first wire coil 110. At least a portion of the second cable 150 is disposed between the second intermediate portion 142 and the second offset portion 143.

When the antenna assembly 120 is rotated in the first direction F1, the second cable 150 follows the outer circumference curvature of the second offset portion 143 (see fig. 23). When the antenna assembly 120 is rotated in the second direction F2, the second cable 150 follows the outer circumference of the second middle portion 142 (see fig. 21). Wherein the first direction F1 and the second direction F2 are opposite.

In other words, the second intermediate portion 142 and the second offset portion 143 of the second wire coil 140 are spaced apart to form a second gap, and the second cable 150 passes through the second gap such that at least a portion of the second cable 150 is positioned between the second intermediate portion 142 and the second offset portion 143, and thus, when the antenna assembly 120 moves in the first direction F1 or the second direction F2, the second cable 150 will wrap around the outer circumference of the second intermediate portion 142 or the second offset portion 143.

Specifically, the antenna module 10 has a first state and a second state. When the antenna module 10 is in the first state, the second cable 150 surrounds the outer periphery of the second middle portion 142 (please refer to fig. 21 in conjunction with fig. 14). When the antenna module 10 is switched from the first state to the second state, the antenna assembly 120 rotates in the first direction F1, the second cable 150 gradually breaks away from the second middle portion 142, and the second cable 150 gradually follows the outer circumference curve of the second offset portion 143 (please refer to fig. 22 in conjunction with fig. 15). When the antenna module 10 is in the second state, the second cable 150 surrounds the outer periphery of the second offset portion 143 (please refer to fig. 23 in conjunction with fig. 16). When the antenna module 10 is switched from the second state to the first state, the antenna assembly 120 rotates in the second direction F2, the second cable 150 gradually breaks away from the second biasing portion 143, and the second cable 150 gradually follows the outer circumference of the second middle portion 142 until being switched to the first state.

It should be noted that, for ease of understanding, the first cable 130 in fig. 21, fig. 22, and fig. 23 is hidden.

Optionally, the first wire reel 110 and the second wire reel 140 are detachably connected, so that assembly and disassembly can be facilitated. The removable connection may be, but is not limited to, a snap fit, a threaded connection, etc.

Alternatively, referring to fig. 24, the first middle portion 112 is hollow, and the first middle portion 112 is provided with a bayonet 1121, and the bayonet 1121 communicates with the internal space of the first middle portion 112. The second middle portion 142 is provided with a buckle 1421, at least a portion of the second middle portion 142 is inserted into the inner space of the first middle portion 112, and the buckle 1421 is located in the bayonet 1121, and the buckle 1421 can prevent the second wire coil 140 from being separated from the first wire coil 110 in a direction away from the antenna assembly 120. Of course, in other embodiments, the snap 1421 and the bayonet 1121 may be exchanged, that is, the first middle portion 112 is provided with the snap 1421, and the second middle portion 142 is provided with the snap 1421, which will not be described in detail herein.

Optionally, referring to fig. 25, the first wire coil 110 further includes a first mating portion 114, the second wire coil 140 further includes a second mating portion 144, the first mating portion 114 and the second mating portion 144 are disposed opposite to each other, and the second mating portion 144 is inserted into the first mating portion 114, or the first mating portion 114 is inserted into the second mating portion 144. By this arrangement, the first and second reels 110 and 140 can be more firmly connected, and the first and second reels 110 and 140 can be prevented from rotating relative to each other.

Alternatively, referring to fig. 15 and 22, a first via K1 is disposed on the first wire coil 110, and the first via K1 penetrates through the first wire coil 110. The second wire coil 140 is provided with a second via hole K2, the second via hole K2 penetrates through the second wire coil 140, and the first via hole K1 and the second via hole K2 are at least partially and oppositely arranged. The first cable 130 passes through the first via K1 and the second via K2. The second cable 150 passes through the second via K2. By the arrangement, the first cable 130 and the second cable 150 can be prevented from being raised to interfere with other components, and the wiring length can be reduced.

Optionally, the rotatable angle of the antenna assembly 120 ranges from 0 ° to 360 °. That is, when the antenna module 10 is in the first state, the antenna assembly 120 can rotate 0 ° to 360 ° (e.g. 10 °, 51 °, 120 °, 286 °) in the first direction F1; when the antenna module 10 is in the second state, the antenna assembly 120 may rotate 0 ° to 360 ° (e.g. 10 °, 51 °, 120 °, 286 °) in the second direction F2. So configured, the antenna assembly 120 may then face in any direction to achieve an optimal orientation. In fig. 14, 15 and 16, the antenna module 10 shown in fig. 15 is a state after the antenna assembly 120 shown in fig. 14 is rotated 180 ° in the first direction F1, and the antenna module 10 shown in fig. 16 is a state after the antenna assembly 120 shown in fig. 14 is rotated 360 ° in the first direction F1. In fig. 21, 22 and 23, the antenna module 10 shown in fig. 22 is a state after the antenna assembly 120 shown in fig. 21 is rotated 180 ° in the first direction F1, and the antenna module 10 shown in fig. 23 is a state after the antenna assembly 120 shown in fig. 21 is rotated 360 ° in the first direction F1.

Referring to fig. 26 and 27 in conjunction with fig. 14 to 16, the antenna assembly 120 further includes a movable wire coil 124, and the movable wire coil 124 includes a plate-shaped portion 1241 and a first winding portion 1242. The plate-shaped portion 1241 is fixed to the second side D2 of the heat sink 121, and the plate-shaped portion 1241 faces the first wire coil 110. The first winding part 1242 is protruded at one side of the plate-shaped part 1241 near the first wire coil 110. As the antenna assembly 120 rotates, the first cable 130 bends in compliance with the outer circumference of the first wire wrap 1242.

The movable wire coil 124 and the radiator 121 may be of a split type structure or an integral type structure. The split structure means that the movable wire coil 124 and the radiator 121 are independently processed and then connected. The integral structure means that the movable wire coil 124 and the radiator 121 are integrally processed. The present application is illustrated by way of example only in a split configuration.

The plate-shaped portion 1241 of the movable wire coil 124 is used for connecting the heat sink 121, and the connection manner may be, but not limited to, bonding, welding, clamping, connection by a bolt or the like. The first winding portion 1242 of the movable wire coil 124 is used to limit the movement and shape of the first cable 130, so that the first cable 130 can bend along the outer circumference of the first winding portion 1242, and the bending radius of all the first sub-cables 131 is the same when bending.

Referring to fig. 14, when the antenna module 10 is in the first state, the first cable 130 is simultaneously bent and attached to the outer periphery of the first winding portion 1242 and the outer periphery of the first offset portion 113. Referring to fig. 16, when the antenna module 10 is in the second state, the first cable 130 is simultaneously bent and attached to the outer periphery of the first winding portion 1242 and the outer periphery of the first middle portion 112. Accordingly, the first winding part 1242 may be engaged with the first wire reel 110 to tension the first cable 130, avoiding the first cable 130 from being loosened.

In the related art, since the first winding part 1242 is not provided, when the first cable 130 is tightened, the first cable 130 is entirely wound around the first intermediate part 112 in a spiral manner, i.e., the latter turn is wound around the outer circumference of the former turn. When the length of the first cable 130 is short or the stress is large, the latter turn is easily embedded in the former turn, so that the latter turn overlaps over the former turn, ultimately resulting in increased friction between the latter and former turns. When the first cable 130 needs to be loosened, the load of the motor 160 increases due to the large friction between the coil bodies, and the power consumption increases.

In this embodiment, since the first winding portion 1242 is provided, the first cable 130 can be wound on the first winding portion 1242 and the first middle portion 112 (or the first offset portion 113) at the same time, so that the first cable 130 can be tightened, and the spiral winding phenomenon of the first cable 130 can be avoided at the same time, thereby overcoming the problems in the related art.

Further, referring to fig. 27 in conjunction with fig. 21 to 23, the movable wire coil 124 further includes a second winding portion 1243. The second winding part 1243 is protruded at one side of the plate-shaped part 1241 near the second wire coil 140. As the antenna assembly 120 rotates, the second cable 150 flexes in compliance with the outer circumference of the second wire wrap 1243. Referring to fig. 21, when the antenna module 10 is in the first state, the second cable 150 is simultaneously bent and attached to the outer periphery of the second winding portion 1243 and the outer periphery of the second middle portion 142. Referring to fig. 23, when the antenna module 10 is in the second state, the second cable 150 is simultaneously bent and attached to the outer periphery of the second winding portion 1243 and the outer periphery of the second biasing portion 143. Accordingly, the second winding part 1243 may draw the second cable 150 in cooperation with the second wire reel 140, avoiding the second cable 150 from being loosened.

Optionally, the height of the second winding portion 1243 protruding from the plate-shaped portion 1241 is greater than the height of the first winding portion 1242 protruding from the plate-shaped portion 1241. It will be appreciated that, since the second wire coil 140 is farther from the antenna assembly 120 than the first wire coil 110, if the protruding heights of the second wire winding portion 1243 and the first wire winding portion 1242 are the same, the second cable 150 will be inclined relative to the plate portion 1241, so that the second wire coil 140 and the second wire winding portion 1243 pull the second cable 150 together, which increases the stress of the second cable 150, and may also make the second cable 150 easily slip from the second wire winding portion 1243 in a direction away from the heat sink 121. In the present embodiment, the second winding portion 1243 is disposed higher, and the second cable 150 may be parallel to the plate portion 1241, thereby overcoming the above-mentioned problem.

Optionally, at least part of the outer surfaces of the first middle portion 112, the first offset portion 113, the second middle portion 142, the second offset portion 143, the first winding portion 1242, and the second winding portion 1243 are cylindrical surfaces, so that the first cable 130 can be curved in an arc shape, thereby protecting the first cable 130.

Optionally, the bending radius of the first cable 130 and the second cable 150 is greater than or equal to 6mm. That is, the bending radius of the outer surfaces of the first middle portion 112, the first offset portion 113, the second middle portion 142, the second offset portion 143, the first winding portion 1242, and the second winding portion 1243 is greater than or equal to 6mm, so that the minimum bending radius of the first cable 130 and the second cable 150 can be limited, thereby avoiding the breakage of the core or the shielding layer of the cable, and further affecting the performance.

Referring to fig. 27, the movable wire coil 124 further includes a first blocking portion 1244 protruding from the plate-shaped portion 1241. The first blocking portion 1244 is located at a side of the first winding portion 1242 facing away from the first wire coil 110, and is opposite to and spaced apart from the first winding portion 1242. At least a portion of the first cable 130 is located between the first blocking portion 1244 and the first winding portion 1242, that is, the first cable 130 will pass through a gap between the first blocking portion 1244 and the first winding portion 1242. It is understood that when the antenna module 10 is in a state between the first state and the second state, the first cable 130 cannot be fully tensioned (as shown in fig. 15), and the first cable 130 may shake due to external shake, so that the first cable 130 cannot contact the first winding portion 1242 any more. In this embodiment, after the first blocking portion 1244 is provided, the first cable 130 is prevented from being pulled out in a direction away from the first wire coil 110.

Further, the movable wire coil 124 further includes a second blocking portion protruding from the plate-shaped portion 1241. The second blocking portion is located at a side of the second winding portion 1243 facing away from the second wire coil 140, and is opposite to and spaced apart from the second winding portion 1243. At least a portion of the second cable 150 is positioned between the second blocking portion and the second winding portion 1243. For the description of the second blocking portion, please refer to the description of the first blocking portion 1244, which is not repeated herein.

Referring to fig. 27, the movable wire coil 124 further includes a first limiting portion 1245, the first limiting portion 1245 is connected to the first winding portion 1242 and/or the first blocking portion 1244, and the first limiting portion 1245 is configured to limit a degree of freedom of the first cable 130 moving in a direction away from the heat sink 121. That is, the first stopper 1245 is connected to at least one of the first winding part 1242 and the first blocking part 1244. In one embodiment, the first limiting portion 1245 is protruding on a side of the first winding portion 1242 facing the first blocking portion 1244, and the first limiting portion 1245 is spaced from the first blocking portion 1244. In another embodiment, the first limiting portion 1245 is protruding on a side of the first blocking portion 1244 facing the first winding portion 1242, and the first limiting portion 1245 is spaced from the first winding portion 1242. In yet another embodiment, the first limiting portion 1245 is connected to both the first winding portion 1242 and the first blocking portion 1244.

The present application is exemplified by the first spacing portion 1245 being connected to the first winding portion 1242, as shown in fig. 27. Although there is a separation distance between the first limiting portion 1245 and the first blocking portion 1244, the separation distance is smaller than the wire diameter of the first sub-cable 131, and therefore, the first cable 130 cannot pass between the first limiting portion 1245 and the first blocking portion 1244, so that the first cable 130 can be completely limited between the first winding portion 1242 and the first blocking portion 1244.

Further, the movable wire coil 124 further includes a second limiting portion, where the second limiting portion is connected to the second winding portion 1243 and/or the second blocking portion, and the second limiting portion is used to limit the degree of freedom of the second cable 150 moving in a direction away from the radiator 121. The second limiting portion is referred to the first limiting portion 1245, and will not be described herein.

It should be noted that the motor 160 may be connected to the heat sink 121 or the movable wire coil 124. In one embodiment, the motor 160 is disposed on a side of the heat sink 121 facing away from the movable wire coil 124, and the motor 160 is connected to the heat sink 121 to achieve the rotation of the antenna assembly 120 as a whole by driving the heat sink 121. In another embodiment, the motor 160 is disposed on the same side of the heat sink 121 as the movable wire coil 124, and the motor 160 is connected to the movable wire coil 124 to achieve the rotation of the antenna assembly 120 as a whole by driving the movable wire coil 124. The latter embodiment is described below with reference to the accompanying drawings.

Referring to fig. 26 and 27, the movable wire coil 124 may further include a connection part 1246 fixedly connected to the plate-shaped part 1241, and the connection part 1246 passes through the first middle part 112 of the first wire coil 110 and the second middle part 142 of the second wire coil 140. The motor 160 is disposed on a side of the second wire coil 140 facing away from the heat sink 121, and the motor 160 is connected to the connection portion 1246, and the motor 160 can drive the connection portion 1246 to rotate, so that the connection portion 1246 drives the whole antenna assembly 120 to rotate. Optionally, the first intermediate portion 112 and the second intermediate portion 142 are each spaced apart from the connecting portion 1246, so as to avoid friction. Further optionally, the antenna module 10 further includes a bearing disposed between the connecting portion 1246 and the first middle portion 112 (or the second middle portion 142), that is, an inner ring of the bearing is sleeved on the outer periphery of the connecting portion 1246, and an outer ring of the bearing is disposed inside the first middle portion 112 (or the second middle portion 142) and abuts against an inner wall of the first middle portion 112 (or the second middle portion 142), so that the first wire coil 110 and the second wire coil 140 can be prevented from being dislocated relative to the antenna assembly 120.

While embodiments of the present application have been shown and described above, it should be understood that the above embodiments are illustrative and not to be construed as limiting the application, and that variations, modifications, alternatives and alternatives to the above embodiments may be made by those skilled in the art within the scope of the application, which is also to be regarded as being within the scope of the application.
