Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to antenna devices and communication equipment. Background Art

[0002] The antenna device is an important component of the communication equipment, which is used to realize the transmission and reception of signals.

[0003] In the related art, there is a whip antenna, which belongs to an external antenna device. The antenna device is fixedly installed on the outer wall of the housing of the communication device.

[0004] However, since the position of the antenna device on the communication device is fixed, its posture cannot be well adjusted, so that the channel condition is affected. Utility Model Content

[0005] The embodiment of the present application provides an antenna device and a communication device to solve the problem that the attitude adjustment dimension of the antenna device is limited. The technical solution is as follows:

[0006] In the first aspect, an antenna device is provided, which includes a vibrator and a posture adjustment mechanism. The vibrator is used to radiate electrical signals, and the posture adjustment mechanism is used to adjust the posture of the vibrator, thereby improving channel conditions. The posture adjustment mechanism includes n rotating shafts connected in sequence, and two adjacent rotating shafts are pivoted or rotatably connected, and n≥3 and is an integer. In other words, the posture adjustment mechanism is composed of n rotating shafts, and the rotating shafts are connected together by being pivoted to each other or being rotatably connected to each other. In addition, since one end of the vibrator is connected to the nth rotating shaft, the vibrator can move in multiple dimensions, thereby flexibly adjusting its own posture, thereby greatly improving the channel conditions.

[0007] The antenna device provided in the embodiment of the present application has at least the following effects:

[0008] Since the rotating shafts are connected together by being pivotally connected or rotatably connected to each other, the rotating shafts can be flexibly moved, so that the vibrator connected to the rotating shaft can also flexibly adjust its posture, thereby greatly improving the channel condition.

[0009] In one implementation of the present application, the connection between two adjacent rotating shafts is pivoted or rotatably connected. There are two arrangements of the two connection modes of pivoting and rotatably connected. The first arrangement is that the mth rotating shaft is rotatably connected to the m-1th rotating shaft, and the m-1th rotating shaft is pivoted to the m-2th rotating shaft. The second arrangement is that the mth rotating shaft is pivoted to the m-1th rotating shaft, and the m-1th rotating shaft is rotatably connected to the m-2th rotating shaft. In these two arrangements, m=n. Through these two arrangements, each rotating shaft can be flexibly moved. In this way, the vibrator connected to the rotating shaft can also flexibly adjust its own posture, thereby greatly improving the channel conditions.

[0010] In one implementation of the present application, the n rotating shafts include a first rotating shaft, a second rotating shaft and a third rotating shaft, that is, the posture adjustment mechanism is composed of the first rotating shaft, the second rotating shaft and the third rotating shaft. The first end of the first rotating shaft is pivoted to the first end of the second rotating shaft, the second end of the second rotating shaft is rotatably connected to the first end of the third rotating shaft, and the vibrator is pivoted to the second end of the third rotating shaft. In this design, through the pivoting between the first rotating shaft and the second rotating shaft, the vibrator can rotate around the pivot axis between the first rotating shaft and the second rotating shaft. Through the rotatable connection between the second rotating shaft and the third rotating shaft, the vibrator can rotate around the rotation axis between the second rotating shaft and the third rotating shaft. Through the pivoting between the vibrator and the third rotating shaft, the vibrator can rotate around the pivot axis between the vibrator and the third rotating shaft. In this way, the vibrator can move in multiple dimensions, so as to flexibly adjust its posture, thereby greatly improving the channel conditions.

[0011] In one implementation of the present application, the pivot axis between the first rotating shaft and the second rotating shaft is perpendicular to the rotation axis between the second rotating shaft and the third rotating shaft. With such a design, the movement dimension between the first rotating shaft and the second rotating shaft, as well as the movement dimension between the second rotating shaft and the third rotating shaft can be utilized to a large extent, which is conducive to flexibly adjusting the posture of the vibrator, thereby greatly improving the channel conditions.

[0012] In one implementation of the present application, the rotation axis between the second rotating shaft and the third rotating shaft is perpendicular to the pivot axis between the third rotating shaft and the vibrator. With such a design, the movement dimension between the second rotating shaft and the third rotating shaft, as well as the movement dimension between the vibrator and the third rotating shaft, can be utilized to a large extent, which is conducive to flexibly adjusting the posture of the vibrator, thereby greatly improving the channel conditions.

[0013] In one implementation of the present application, the second rotating shaft is a hollow structural member, and the first rotating shaft and the third rotating shaft are respectively inserted into the second rotating shaft. In this way, based on the second rotating shaft, the first rotating shaft and the third rotating shaft can both be inserted into the second rotating shaft, which effectively reduces the volume of the posture adjustment mechanism, thereby facilitating the miniaturization design of the antenna device.

[0014] In one implementation of the present application, the outer wall of the second rotating shaft has two first clearance gaps arranged opposite to each other. The two first clearance gaps are close to the first end of the second rotating shaft, and one of the first clearance gaps is located on one side of the pivot axis between the first rotating shaft and the second rotating shaft, and the other first clearance gap is located on the other side of the pivot axis between the first rotating shaft and the second rotating shaft. With such a design, the two first clearance gaps can provide space for the pivotal swing between the first rotating shaft and the second rotating shaft, avoiding interference between the first rotating shaft and the second rotating shaft during the pivotal swing due to the insertion of the first rotating shaft into the second rotating shaft.

[0015] In a second aspect, a communication device is provided, the communication device comprising a device body and the antenna device described in the first aspect. The posture adjustment mechanism of the antenna device is connected to the device body, and the vibrator of the antenna device is located outside the device body. The device body provides an installation base for the antenna device, and the vibrator is located outside the device body, so that there is sufficient space to adjust its posture.

[0016] The communication device provided in the embodiment of the present application has at least the following effects:

[0017] Since the rotating shafts are connected together by being pivotally connected or rotatably connected to each other, the rotating shafts can be flexibly moved, so that the vibrator connected to the rotating shaft can also flexibly adjust its posture, thereby greatly improving the channel condition.

[0018] In one implementation of the present application, the communication device includes two antenna devices, and the two antenna devices are arranged at intervals from each other. Such a design can better improve channel conditions, thereby improving the communication capability of the communication device.

[0019] In one implementation of the present application, the outer wall of the device body has an axle seat, and the first rotating shaft of the posture adjustment mechanism is rotatably inserted into the axle seat. The axle seat is used to provide a stable installation base for the first rotating shaft of the posture adjustment mechanism, and because the rotating shaft and the axle seat are rotatably connected, the movement dimension of the vibrator can be further increased, so as to flexibly adjust its own posture, thereby greatly improving the channel conditions.

DETAILED DESCRIPTION

[0037] The terms used in the implementation section of the present application are only used to explain the embodiments of the present application and are not intended to limit the present application.

[0038] The present application embodiment provides a communication device, Figure 1 For a schematic diagram of the structure of the communication equipment, see Figure 1 The communication device includes a device body 100 and an antenna device. The antenna device is located outside the device body 100, and the antenna device is connected to the outer wall of the device body 100.

[0039] When the communication device is working, the antenna device can realize the transmission and reception of signals. Therefore, the performance of the antenna device largely determines the signal transmission and reception capability of the communication device. The antenna device is described below.

[0040] Figure 2 is a schematic diagram of the structure of the antenna device, see Figure 2 In this embodiment, the antenna device includes a vibrator 10 and a posture adjustment mechanism 20. The posture adjustment mechanism 20 includes n rotating shafts 210 connected in sequence, two adjacent rotating shafts 210 are pivotally connected or rotatably connected, and the rotation axis between two adjacent rotating shafts 210 extends along the axial direction of the corresponding rotating shaft 210, n≥3, and is an integer. One end of the vibrator 10 is connected to the nth rotating shaft 210.

[0041] That is, the posture adjustment mechanism 20 is composed of n rotating shafts 210, and the rotating shafts 210 are connected together by being pivotally connected to each other or being rotatably connected to each other. In addition, since one end of the vibrator 10 is connected to the nth rotating shaft 210, the vibrator 10 can move in multiple dimensions, thereby flexibly adjusting its own posture, thereby greatly improving the channel condition.

[0042] Since the rotating shafts 210 are connected together by being pivotally connected or rotatably connected to each other, the rotating shafts 210 can be flexibly moved. In this way, the vibrator 10 connected to the rotating shaft 210 can also flexibly adjust its posture, thereby greatly improving the channel condition.

[0043] In this embodiment, two adjacent rotating shafts 210 are pivotally connected, which means that the two rotating shafts 210 are connected and can swing relative to each other about the pivot axis.

[0044] In this embodiment, two adjacent rotating shafts 210 are rotatably connected, which means that the two rotating shafts 210 are connected and can rotate relative to each other about the rotation axis, and the rotation axis between the two adjacent rotating shafts 210 extends along the axial direction of the corresponding rotating shaft 210. Exemplarily, the rotation axis between the two adjacent rotating shafts 210 is coaxial with the corresponding two rotating shafts 210.

[0045] In this embodiment, the pivot axis between two connected rotating shafts 210 and the rotation axis between two adjacent rotating shafts 210 are perpendicular to each other.

[0046] In this embodiment, the connection between two adjacent rotating shafts 210 is pivotally connected or rotatably connected. There are two arrangements of the two connection modes of pivotally connected and rotatably connected.

[0047] The first arrangement is that the m-th rotating shaft 210 is rotatably connected to the m-1-th rotating shaft 210, and the m-1-th rotating shaft 210 is pivotally connected to the m-2-th rotating shaft 210, where m=n.

[0048] The second arrangement is that the m-th rotating shaft 210 is pivotally connected to the m-1-th rotating shaft 210, and the m-1-th rotating shaft 210 is rotatably connected to the m-2-th rotating shaft 210, where m=n.

[0049] Through these two arrangements, the shafts 210 can be flexibly moved, so that the vibrator 10 connected to the shaft 210 can also flexibly adjust its posture, thereby greatly improving the channel condition.

[0050] Figure 3 It is a structural diagram of the posture adjustment mechanism. Figure 3In this embodiment, the n rotating shafts 210 include a first rotating shaft 211, a second rotating shaft 212 and a third rotating shaft 213. The first end of the first rotating shaft 211 is pivotally connected to the first end of the second rotating shaft 212, the second end of the second rotating shaft 212 is rotatably connected to the first end of the third rotating shaft 213, and the vibrator 10 is pivotally connected to the second end of the third rotating shaft 213.

[0051] The posture adjustment mechanism 20 is composed of a first rotating shaft 211, a second rotating shaft 212 and a third rotating shaft 213. With such a design, the vibrator 10 can rotate around the pivot axis between the first rotating shaft 211 and the second rotating shaft 212 through the pivot connection between the first rotating shaft 211 and the second rotating shaft 212. The vibrator 10 can rotate around the rotation axis between the second rotating shaft 212 and the third rotating shaft 213 through the rotatable connection between the second rotating shaft 212 and the third rotating shaft 213. The vibrator 10 can rotate around the pivot axis between the vibrator 10 and the third rotating shaft 213 through the pivot connection between the vibrator 10 and the third rotating shaft 213. In this way, the vibrator 10 can move in multiple dimensions, thereby flexibly adjusting its own posture, thereby greatly improving the channel conditions.

[0052] Exemplarily, the pivot axis between the first rotating shaft 211 and the second rotating shaft 212 is perpendicular to the rotation axis between the second rotating shaft 212 and the third rotating shaft 213 .

[0053] In the above implementation, the movement dimension between the first rotation axis 211 and the second rotation axis 212, and the movement dimension between the second rotation axis 212 and the third rotation axis 213 can be utilized to a large extent, which is conducive to flexible adjustment of the posture of the vibrator 10, thereby greatly improving the channel conditions.

[0054] Of course, in other embodiments, the pivot axis between the first rotating shaft 211 and the second rotating shaft 212 and the rotation axis between the second rotating shaft 212 and the third rotating shaft 213 can also be an acute angle or an obtuse angle. The angles of the acute angle and the obtuse angle can be adjusted according to actual needs, and this application does not limit this.

[0055] Exemplarily, the rotation axis between the second rotation shaft 212 and the third rotation shaft 213 is perpendicular to the pivot axis between the third rotation shaft 213 and the vibrator 10 .

[0056] In the above implementation, the movement dimension between the second rotation axis 212 and the third rotation axis 213, and the movement dimension between the vibrator 10 and the third rotation axis 213 can be utilized to a large extent, which is conducive to flexible adjustment of the posture of the vibrator 10, thereby greatly improving the channel condition.

[0057] Of course, in other embodiments, the rotation axis between the second rotating shaft 212 and the third rotating shaft 213 and the pivot axis between the third rotating shaft 213 and the vibrator 10 may also be an acute angle or an obtuse angle. The acute angle and the obtuse angle may be adjusted according to actual needs, and the present application does not limit this.

[0058] In this embodiment, the second rotating shaft 212 is a hollow structural member, and the first rotating shaft 211 and the third rotating shaft 213 are respectively inserted into the second rotating shaft 212 .

[0059] In this way, based on the second rotating shaft 212, the first rotating shaft 211 and the third rotating shaft 213 can be inserted into the second rotating shaft 212, so that the assembly between the first rotating shaft 211, the second rotating shaft 212, and the third rotating shaft 213 is more compact, and the volume of the posture adjustment mechanism 20 is effectively reduced, which is conducive to the miniaturization design of the antenna device.

[0060] In this embodiment, the outer wall of the second rotating shaft 212 has two first clearance gaps 214 arranged opposite to each other, the two first clearance gaps 214 are close to the first end of the second rotating shaft 212, and one first clearance gap 214 is located on one side of the pivot axis between the first rotating shaft 211 and the second rotating shaft 212, and the other first clearance gap 214 is located on the other side of the pivot axis between the first rotating shaft 211 and the second rotating shaft 212.

[0061] In the above implementation, the two first clearance gaps 214 are respectively located on the movement tracks of the mutual swing between the first rotating shaft 211 and the second rotating shaft 212. With such a design, the two first clearance gaps 214 can provide space for the pivotal swing between the first rotating shaft 211 and the second rotating shaft 212, thereby avoiding the interference problem between the first rotating shaft 211 and the second rotating shaft 212 during the pivotal swing due to the insertion of the first rotating shaft 211 into the second rotating shaft 212.

[0062] In this embodiment, the outer wall of the vibrator 10 has a second clearance gap 110 , which is located at one end of the vibrator 10 close to the third rotation axis 213 and one side of the pivot axis between the vibrator 10 and the third rotation axis 213 .

[0063] In the above implementation, the second clearance gap 110 is located on the motion trajectory of the mutual swing between the vibrator 10 and the third rotating shaft 213. With such a design, the second clearance gap 110 can provide space for the pivotal swing between the vibrator 10 and the third rotating shaft 213, thereby avoiding the interference problem between the third rotating shaft 213 and the vibrator 10 during the pivotal swing caused by the third rotating shaft 213 being inserted into the vibrator 10.

[0064] Of course, in other embodiments, the outer wall of the vibrator 10 has two second clearance gaps 110 , and the two second clearance gaps 110 are respectively located on two opposite sides of the pivot axis between the vibrator 10 and the third rotating shaft 213 .

[0065] The following is a brief introduction to the assembly method of the antenna device:

[0066] First, the vibrator 10 and the third rotating shaft 213 are assembled together by pivoting, so that the second clearance notch 110 on the vibrator 10 is located on one side of the pivot axis between the vibrator 10 and the third rotating shaft 213 .

[0067] Next, the third rotating shaft 213 is inserted into the second end of the second rotating shaft 212 , so that the third rotating shaft 213 and the second rotating shaft 212 are coaxially arranged and can rotate relative to each other.

[0068] Finally, the first rotating shaft 211 is inserted into the first end of the second rotating shaft 212, so that the first rotating shaft 211 and the second rotating shaft 212 are assembled together by pivoting, and the first clearance notch 214 on the second rotating shaft 212 is respectively located on the opposite sides of the pivot axis between the first rotating shaft 211 and the second rotating shaft 212.

[0069] Through the above steps, the assembly of the antenna device can be completed.

[0070] It is worth noting that, since the vibrator 10, the first rotating shaft 211, the second rotating shaft 212 and the third rotating shaft 213 are independent of each other, the assembly sequence of the components can be adjusted according to actual needs, and the present application does not impose any restrictions on this.

[0071] The following describes how the antenna device is configured on the communication device.

[0072] See again Figure 1 In this embodiment, the communication device includes a device body 100 and Figure 2 In the antenna device shown, the posture adjustment mechanism 20 of the antenna device is connected to the device body 100 , and the vibrator 10 of the antenna device is located outside the device body 100 .

[0073] The device body 100 provides an installation base for the antenna device, and the vibrator 10 is located outside the device body 100, so there is sufficient space to adjust its posture. Since the shafts 210 are connected to each other by pivoting or rotatably connecting to each other, the shafts 210 can be flexibly moved. In this way, the vibrator 10 connected to the shaft 210 can also flexibly adjust its posture, thereby greatly improving the channel conditions.

[0074] In this embodiment, the outer wall of the device body 100 has a shaft seat 1100 , and the first rotating shaft 210 of the posture adjustment mechanism 20 is rotatably inserted into the shaft seat 1100 .

[0075] Among them, the shaft seat 1100 is used to provide a stable installation foundation for the first rotating shaft 210 of the attitude adjustment mechanism 20, and because the rotating shaft 210 and the shaft seat 1100 are rotatably connected, the movement dimension of the vibrator 10 can be further increased, so as to flexibly adjust its own attitude, thereby greatly improving the channel conditions.

[0076] For example, one end of the first rotating shaft 211 away from the second rotating shaft 212 is rotatably inserted into the shaft seat 1100 , so that the first rotating shaft 211 can rotate relative to the device body 100 .

[0077] Figure 4 The structural diagram of the shaft seat is shown in Figure 2. Figure 4 In this embodiment, the shaft seat 1100 has a limiting protrusion 1101 at one end facing the first rotating shaft 211. The limiting protrusion 1101 extends along the circumference of the shaft seat 1100 and has a movable notch 1102. The outer wall of the first rotating shaft 211 has a limiting protrusion 215. The limiting protrusion 215 is located in the movable notch 1102, and the limiting protrusion 1101 is located on the movable track of the limiting protrusion 215.

[0078] In the above implementation, the limiting protrusion 215 rotates together with the first rotating shaft 211. The limiting protrusion 215 can move freely in the movable notch 1102 without being limited. If the limiting protrusion 215 touches the end of the limiting protrusion ring 1101, the limiting protrusion ring 1101 will limit the limiting protrusion 215. In other words, by designing the size of the limiting protrusion ring 1101 and the movable notch 1102, the range of motion of the limiting protrusion 215 can be effectively limited, that is, the rotation angle of the first rotating shaft 211 can be limited, thereby avoiding the difficulty in controlling the posture adjustment of the vibrator 10 due to excessive rotation of the first rotating shaft 211.

[0079] In some examples, a circular hole is provided in the shaft seat 1100 , and the first rotating shaft 211 is inserted into the circular hole, so that the first rotating shaft 211 is rotatably inserted into the shaft seat 1100 .

[0080] In other examples, the shaft seat 1100 has at least two intersecting strip holes, and the first rotating shaft 211 can move in the strip holes, thereby further increasing the moving range of the first rotating shaft 211 .

[0081] Exemplarily, the shaft seat 1100 has two vertically intersecting strip holes, and the device body 100 has an electric drive mechanism, which is transmission-connected to the first rotating shaft 211, so as to drive the first rotating shaft 211 to move in the strip holes.

[0082] Exemplarily, with the intelligent antenna training algorithm, the position of the antenna device can be adjusted in real time according to the actual environment, thereby improving the automation capability of the communication equipment.

[0083] Exemplarily, the communication device includes two antenna devices, and the two antenna devices are arranged spaced apart from each other.

[0084] Such a design can better improve channel conditions, thereby enhancing the communication capabilities of communication equipment.

[0085] As can be seen from the foregoing, the posture adjustment mechanism 20 enables the vibrator 10 to have a variety of postures relative to the device body 100, which will be exemplified below.

[0086] The first attitude, see Figure 5 In this posture, the horizontal distance between the two vibrators 10 is the shortest, and it is used as the basic posture to facilitate the comparison of other postures.

[0087] The second attitude, see Figure 6 , this attitude is compared to Figure 5 For the basic posture shown, the angles of the two vibrators 10 are adjusted.

[0088] The third attitude, see Figure 7 , this attitude is compared to Figure 5 For the basic posture shown, the distance between the two vibrators 10 in the horizontal direction is adjusted.

[0089] The fourth attitude, see Figure 8 , this attitude is compared to Figure 5 For the basic posture shown, the distance between the two vibrators 10 in the vertical direction is adjusted.

[0090] It is worth noting that the above four postures are only examples and are not intended to limit the communication device provided in the embodiments of the present application.
