The auxiliary antenna component comprises a supporting frame, a driving assembly, a connecting frame and an auxiliary antenna body. After the driving assembly drives the auxiliary antenna body to move in the axial direction of the connecting frame and the auxiliary antenna body is in lap joint with the main antenna, the auxiliary antenna body can prolong the length of the main antenna. In this way, the main antenna can transmit or receive a radio signal at the extended length, the frequency of which is adapted to the extended length. Similarly, after the auxiliary antenna body is separated from the main antenna, the main antenna can transmit or receive radio signals with the original length, and the frequency of the radio signals is matched with the original length of the main antenna. Therefore, the length of the main antenna can be changed through the auxiliary antenna component, so that the main antennas with different lengths can transmit or receive radio signals with different frequencies, and the main antennas can transmit or receive the radio signals with different frequencies at the highest transmitting or receiving efficiency.

Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to an auxiliary antenna component and an electronic device. Background Art

[0002] The application of antennas in electronic devices enables electronic devices to perform wireless communication. With the development of electronic devices, electronic devices need to be able to use radio signals of different frequencies for wireless communication. To this end, the antennas in electronic devices must adapt to radio signals of different frequencies.

[0003] However, the frequency of the radio signal is related to the length of the antenna. If the antenna transmits or receives the radio signal with a length that does not match the frequency of the radio signal to be transmitted or received, the efficiency of the antenna in transmitting or receiving the radio signal is low. However, if antennas of different lengths are installed in electronic devices to receive or transmit radio signals of different frequencies, the size of the electronic device will increase accordingly.

[0040] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0041] An embodiment of the present application provides an auxiliary antenna component. Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of a structure in which an auxiliary antenna component provided by an embodiment of the present application cooperates with a main antenna, Figure 2 and

[0042] which is a schematic structural diagram of another structure in which an auxiliary antenna component provided by an embodiment of the present application cooperates with a main antenna. The auxiliary antenna component 000 may include: a support frame 100, a driving component 200, a connecting frame 300, and an auxiliary antenna body 400.

[0043] Among them, the driving component 200 in the auxiliary antenna component 000 can be configured to drive the auxiliary antenna body 400 to move axially on the connecting frame 300, so that the auxiliary antenna body 400 overlaps with the main antenna 010, or separates the auxiliary antenna body 400 from the main antenna 010.

[0044] It should be noted that the main antenna 010 is made of metal to realize the transmission or reception of radio signals by the main antenna 010. The auxiliary antenna body 400 in the auxiliary antenna component 000 can also be metal. In this way, after the driving component 200 drives the auxiliary antenna body 400 to move axially on the connecting frame and the auxiliary antenna body 400 overlaps with the main antenna 010, the auxiliary antenna body 400 can be used as an antenna for transmitting and receiving radio signals together with the main antenna 010. That is to say, the auxiliary antenna body 400 can extend the length of the main antenna 010. Similarly, after the driving component 200 drives the auxiliary antenna body 400 to move axially on the connecting frame and separates the auxiliary antenna body 400 from the main antenna 010, the main antenna 010 can transmit or receive radio signals at its original length.

[0045] It should also be noted that as Figure 2 shown, when the length of the auxiliary antenna body 400 is not much different from the length of the main antenna 010, after the auxiliary antenna body 400 overlaps with the main antenna 010, the length of the main antenna 010 can be significantly extended. Furthermore, the frequency at which the main antenna 010 with the extended length can transmit or receive radio signals can be changed greatly.

[0046] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of another cooperation between the auxiliary antenna component and the main antenna provided by the embodiment of the present application. When the length of the auxiliary antenna body 400 is quite different from the length of the main antenna 010, even if the auxiliary antenna body 400 overlaps with the main antenna 010, the length of the main antenna 010 is not significantly extended. Furthermore, the frequency at which the main antenna 010 with the extended length can transmit or receive radio signals does not change greatly. In this case, after the auxiliary antenna body 400 overlaps with the main antenna 010, the auxiliary antenna body 400 can also overlap with the metal part 020, and the metal part 020 can be separately arranged from the main antenna 010. In this way, after the auxiliary antenna body 400 overlaps with both the main antenna 010 and the metal part 020 at the same time, the main antenna 010, the auxiliary antenna body 400, and the metal part 020 can be used as an antenna for transmitting or receiving radio signals together. That is to say, the auxiliary antenna body 400 and the metal part 020 can extend the length of the main antenna 010 together.

[0047] It should also be noted that when the length of the antenna is one - quarter of the wavelength of the radio signal, the efficiency of the antenna for transmitting and receiving the radio signal is the highest.

[0048] In the present application, when the driving component 200 drives the auxiliary antenna body 400 to move axially on the connecting frame 200 and the auxiliary antenna body 400 overlaps with the main antenna 010, the auxiliary antenna body 400 can extend the length of the main antenna 010. In this way, the main antenna 010 can transmit or receive radio signals whose frequencies are adapted to its extended length. Similarly, when the driving component 200 drives the auxiliary antenna body 400 to move axially on the connecting frame 300 and the auxiliary antenna body 400 is separated from the main antenna 010, the main antenna 010 can transmit or receive radio signals whose frequencies are adapted to its original length. Therefore, through this auxiliary antenna component 000, the length of the main antenna 010 can be changed, so that main antennas 010 with different lengths can transmit or receive radio signals with different frequencies, and it is ensured that the main antenna 010 can transmit or receive radio signals with different frequencies with the highest transmission or reception efficiency.

[0049] In summary, the embodiment of the present application provides an auxiliary antenna component, including: a support frame, a driving component, a connecting frame, and an auxiliary antenna body. When the driving component drives the auxiliary antenna body to move axially on the connecting frame and the auxiliary antenna body overlaps with the main antenna, the auxiliary antenna body can extend the length of the main antenna. In this way, the main antenna can transmit or receive radio signals whose frequencies are adapted to its extended length. Similarly, after the auxiliary antenna body is separated from the main antenna, the main antenna can transmit or receive radio signals whose frequencies are adapted to its original length. Therefore, through this auxiliary antenna component, the length of the main antenna can be changed, so that main antennas with different lengths can transmit or receive radio signals with different frequencies, and it is ensured that the main antenna can transmit or receive radio signals with different frequencies with the highest transmission or reception efficiency.

[0050] Optionally, please refer to Figure 4 and Figure 5 , Figure 4 which is a schematic structural diagram of an auxiliary antenna component provided by the embodiment of the present application. Figure 5It is a schematic structural diagram of another auxiliary antenna component provided by an embodiment of the present application. The driving component 200 in the auxiliary antenna component 000 may include: a deformation member 201. The deformation member 201 in the driving component 200 may be used to generate deformation to drive the auxiliary antenna body 400 to move in the axial direction of the connecting frame 300 in a direction away from the deformation member 201, so that the auxiliary antenna body 400 overlaps with the main antenna 010. Alternatively, the deformation member 201 in the driving component 200 may be used to drive the auxiliary antenna body 400 to move in the axial direction of the connecting frame 300 in a direction towards the deformation member 201 during the recovery process after the deformation of the deformation member 201, so that the auxiliary antenna body 400 is separated from the main antenna 010.

[0051] It should be noted that during the deformation of the deformation member 201, the deformation member 201 can drive the connecting frame 300 to move in a direction away from the deformation member 201, and further drive the auxiliary antenna body 400 to move in the axial direction of the connecting frame 300 in a direction away from the deformation member 201, that is, it can drive the auxiliary antenna body 400 to move in a direction towards the main antenna 010 until the auxiliary antenna body 400 can overlap with the main antenna 010. During the recovery process after the deformation of the deformation member 201, the deformation member 201 can drive the connecting frame 300 to move in a direction towards the deformation member 201, and further drive the auxiliary antenna body 400 to move in the axial direction of the connecting frame 300 in a direction towards the deformation member 201, that is, it can drive the auxiliary antenna body 400 to move in a direction away from the main antenna 010 until the deformation of the deformation member 201 is completely recovered and the auxiliary antenna body 400 can be separated from the main antenna 010.

[0052] In the present application, as Figure 4 and Figure 5 shown, the deformation member 201 may include: a deformation layer 2011, a first conductive layer 2012, and a second conductive layer 2013. The first conductive layer 2012 in the deformation member 201 may be located on the side of the deformation layer 2011 away from the auxiliary antenna body 400, and the second conductive layer 2013 may be located on the side of the deformation layer 2011 towards the auxiliary antenna body 400. The connecting frame 300 may be connected to the side of the second conductive layer 2013 in the deformation member 201 away from the deformation layer 2011.

[0053] Among them, when the first conductive layer 2012 in the deformable member 201 is positively charged and the second conductive layer 2013 is negatively charged, the deformation layer 2011 in the deformable member 201 can bend in the direction towards the auxiliary antenna body 400. In this way, during the process of the deformation layer 2011 bending in the direction towards the auxiliary antenna body 400, the connecting frame 300 connected to the second conductive layer 2013 can move in the direction towards the auxiliary antenna body 400, so as to drive the auxiliary antenna body 400 to move in the direction towards the main antenna 010 until the auxiliary antenna body 400 overlaps with the main antenna 010.

[0054] When both the first conductive layer 2012 and the second conductive layer 2013 in the deformable member 201 are not charged, the deformation layer 2011 in the deformable member 201 can be in a flat plate shape. That is to say, after the first conductive layer 2012 is positively charged and the second conductive layer 2013 is negatively charged to cause the deformation layer 201 to deform, if it is necessary to separate the auxiliary antenna body 400 from the main antenna 010, the first conductive layer 2012 and the second conductive layer 2013 can be made not charged. In this way, the deformed deformation layer 2011 can gradually return to its original flat plate shape. And during the recovery process of the deformation of the deformation layer 2011, the connecting frame 300 connected to the second conductive layer 2013 can move in the direction towards the deformable member 201, so as to drive the auxiliary antenna body 400 to move in the direction away from the main antenna 010 until the auxiliary antenna body 400 is separated from the main antenna 010.

[0055] It should be noted that as Figure 4 and Figure 5 shown, the first conductive layer 2012 and the second conductive layer 2013 in the deformable member 201 can be silver-plated electrodes formed on both sides of the deformation layer 2011. Both ends of the first conductive layer 2012 can be connected to the power supply through the first pole piece 2012a, and both ends of the second conductive layer 2013 can be connected to the power supply through the second pole piece 2013a. By conducting the power supply with the first pole piece 2012a and the second pole piece 2013a, the first electrode layer 2012 can be positively charged, and the second electrode layer 2013 can be negatively charged. By turning off the power supply from the first pole piece 2012a and the second pole piece 2013a, both the first electrode layer 2012 and the second electrode layer 2013 can be not charged.

[0056] It should also be noted that the deformation layer 2011 in the deformable member 201 can be a piezoelectric ceramic. When the first electrode layer 2012 is positively charged and the second electrode layer 2013 is negatively charged, the deformation layer 2011 which is a piezoelectric ceramic can bend in the direction towards the auxiliary antenna body 400 under the action of the electric field; when both the first electrode layer 2012 and the second electrode layer 2013 are not charged, the deformation layer 2011 which is a piezoelectric ceramic can return to a flat plate shape.

[0057] In this application, please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another auxiliary antenna component provided by an embodiment of this application. The driving component 200 in the auxiliary antenna component 000 may include: a plurality of deformation members 201. Among them, the plurality of deformation members 201 in the driving component 200 may be stacked along the axial direction of the connecting frame 300, and the driving component 200 may further include: an insulating layer 202 located between two adjacent deformation members 201. In this way, through the bending of the plurality of deformation layers 2012 in the plurality of deformation members 201 arranged in layers in the direction towards the auxiliary antenna body 400, the distance that the auxiliary antenna body 400 moves in the direction towards the main antenna 010 can be increased. In this way, when the distance between the auxiliary antenna body 400 and the main antenna 010 is relatively large, a plurality of deformation members 201 can be arranged in the driving component 200 to increase the distance that the driving component 200 drives the auxiliary antenna body 400 to move, ensuring that the auxiliary antenna body 400 can overlap with the main antenna 010.

[0058] Optionally, as Figure 4 , Figure 5 and Figure 6 shown, the auxiliary antenna component 000 may further include: a flexible insulating part 500. The flexible insulating part 500 in the auxiliary antenna component 000 may be connected to the edge part of the deformation member 201 in the driving component 200, and the flexible insulating part 500 can cover the edges of the first conductive layer 2012 and the second conductive layer 2013 in the deformation member 201. In this way, after the first conductive layer 2012 and the second conductive layer 2013 in the deformation member 201 are charged, the flexible insulating part 500 ensures that the charged first conductive layer 2012 and second conductive layer 2013 will not affect the main antenna 010's transmission and reception of radio signals. And since the flexible insulating part 500 is made of a flexible material, after the deformation member 201 deforms, the flexible insulating part 500 can eliminate the acting force between the deformation member 201 and the support frame 100 to avoid damage to the deformation member 201 and the support frame 100.

[0059] Optionally, as Figure 4 and Figure 5 shown, the support frame 100 in the auxiliary antenna component 000 may have a mounting groove, and the flexible insulating part 500 in the auxiliary antenna component 000 may be fixedly connected to the support frame 100 in the mounting groove of the support frame 100.

[0060] In this application, the structure of the connecting frame 300 in the auxiliary antenna component 000 may have the following two situations:

[0061] In the first case, as Figure 4 and Figure 5As shown, the connecting frame 300 in the auxiliary antenna component 000 may include: a first connecting rod 301 and a bracket 302. One end of the first connecting rod 301 in the connecting frame 300 may be fixedly connected to the driving component 200. For example, one end of the first connecting rod 301 in the connecting frame 300 may be fixedly connected to the deformable member 201 in the driving component 200. The other end of the first connecting rod 301 in the connecting frame 300 may be fixedly connected to the bracket 302. One side of the bracket 302 in the connecting frame 300 facing away from the first connecting rod 301 may be connected to the auxiliary antenna body 400.

[0062] Exemplarily, after the deformable member 201 in the driving component 200 deforms, the first connecting rod 301 fixedly connected to the deformable member 201 may move in a direction away from the driving component 200 under the action of the deformation of the deformable member 201. Since one side of the bracket 302 fixedly connected to the first connecting rod 301 facing away from the first connecting rod 301 is connected to the auxiliary antenna body 400, the first connecting rod 301 that moves under the action of the deformation of the deformable member 201 may drive the auxiliary antenna body 400 to move in a direction toward the main antenna 010 by driving the bracket 302 to move.

[0063] Similarly, during the recovery process of the deformation of the deformable member 201 in the driving component 200, the deformable member 201 may drive the first connecting rod 301 fixedly connected to the deformable member 201 to move in a direction toward the driving component 200. Since one side of the bracket 302 fixedly connected to the first connecting rod 301 facing away from the first connecting rod 301 is connected to the auxiliary antenna body 400, the deformable member 201 may further drive the auxiliary antenna body 400 to move in a direction away from the main antenna 010 by driving the bracket 302 to move.

[0064] Optionally, please refer to Figure 7 , Figure 7 FIG. is a schematic structural diagram of another auxiliary antenna component provided by an embodiment of the present application. The support frame 100 in the auxiliary antenna component 000 may have a plurality of positioning pins 101. The extending direction of the positioning pins 101 in the support frame 100 may be parallel to the axial direction of the first connecting rod 301. The bracket 302 in the connecting frame 300 may have a plurality of first positioning holes K1 corresponding one-to-one to the plurality of positioning pins 101 in the support frame 100. At least a part of the positioning pins 101 may be located in the corresponding first positioning holes K1, and the positioning pins 101 can move in the first positioning holes K1. In this way, during the process of the driving component 200 driving the connecting frame 300 to move, by restricting the movement of the positioning pins 101 in the support frame 100 in the corresponding first positioning holes K1, the movement of the connecting frame 300 can be restricted, ensuring that the auxiliary antenna body 400 can accurately overlap with the main antenna 010 under the drive of the connecting frame 300.

[0065] In the second case, please refer to Figure 8 , Figure 8 which is a schematic structural diagram of an auxiliary antenna component provided by another embodiment of the present application. On the basis of the first case, the connecting frame 300 in the auxiliary antenna component 000 may further include a rotating rod 303 that abuts against a side of the bracket 302 facing away from the first connecting rod 301. The support frame 100 in the auxiliary antenna component 000 may further have a connecting portion 102. The first end of the rotating rod 303 in the adapter frame 300 may be rotatably connected to the connecting portion 102 in the support frame 100. The second end of the rotating rod 303 may abut against a side of the auxiliary antenna body 400 facing the driving component 200, and the second end of the rotating rod 303 can slide on the side of the auxiliary antenna body 400 facing the driving component 200. It should be noted that one end of the bracket 302 facing away from the first connecting rod 301 can slide on a side of the rotating rod 303 facing the driving component 200.

[0066] For example, after the deformation member 201 in the driving component 200 deforms, the first connecting rod 301 fixedly connected to the deformation member 201 can move in a direction away from the driving component 200 under the action of the deformation of the deformation member 201, and then can drive the bracket 302 to move in a direction away from the driving member 200. In this way, since one end of the bracket 302 facing away from the first connecting rod 301 abuts against the rotating rod 303 and one end of the bracket 302 facing away from the first connecting rod 301 can slide on a side of the rotating rod 303 facing the driving component 200, therefore, driven by the movement of the bracket 302, the rotating rod 303 can rotate in a direction away from the driving component 200 through the rotational connection between the first end of the rotating rod 303 and the connecting portion 102. Furthermore, since the second end of the rotating rod 303 abuts against a side of the auxiliary antenna body 400 facing the driving component 200 and the second end of the rotating rod 303 can slide on the side of the auxiliary antenna body 400 facing the driving component 200, therefore, driven by the rotating rod 303, the auxiliary antenna body 400 can move on a side away from the driving component 200, that is, the auxiliary antenna body 400 can move in a direction towards the main antenna 010 to overlap with the main antenna 010.

[0067] It should be noted that, in the second case, the connecting frame 300 may include the rotating rod 303. In this way, compared with the structure of the connecting frame 300 in the first case, by driving the movement of the auxiliary antenna body 400 through the rotating rod 303, the distance that the auxiliary antenna body 400 moves in the direction towards the main antenna 010 can be increased. In this way, when the distance between the auxiliary antenna body 400 and the main antenna 010 is relatively large, the structure of the adapter frame 300 in the second case can also be adopted to increase the distance that the driving component 200 drives the auxiliary antenna body 400 to move, ensuring that the auxiliary antenna body 400 can overlap with the main antenna 010.

[0068] Optional, such as Figure 8 and Figure 9 As shown, Figure 9 It is a structural schematic diagram of another auxiliary antenna component provided by another embodiment of the present application. The auxiliary antenna body 400 in the auxiliary antenna component 000 may have a plurality of second positioning holes K2 corresponding one to one with the plurality of positioning pins 101. The positioning pins 101 in the support frame 100 can pass through the first positioning hole K1 and the second positioning hole K2 in sequence. Here, since the second end of the rotating rod 303 is in contact with the side of the auxiliary antenna body 400 facing the driving assembly 200, the movement of the auxiliary antenna body 400 can be limited by limiting the movement of the positioning pin 101 in the support frame 100 in the second positioning hole K2 of the auxiliary antenna body 400, thereby ensuring that the auxiliary antenna body 400 can be accurately overlapped with the main antenna 010 under the drive of the rotating rod 303.

[0069] Optional, such as Figure 8 and Figure 9 As shown, the support frame 100 in the auxiliary antenna component 000 may also have: a plurality of abutment portions 103 corresponding to the plurality of positioning pins 101, and a plurality of elastic elements 104 corresponding to the plurality of positioning pins 101. The abutment portion 103 in the support frame 100 may be located on the side of the auxiliary antenna body 400 away from the bracket 302, and may be fixedly connected to the end of the corresponding positioning pin 101. The elastic element 104 in the support frame 100 may be sleeved on the corresponding positioning pin 101, and may be located between the auxiliary antenna body 400 and the corresponding abutment portion 103.

[0070] It should be noted that the elastic element 104 in the support frame 100 can be a compressed elastic element, that is, the elastic element 104 can store an outward elastic force. In this way, during the recovery process of the deformation of the deformable member 201 in the driving assembly 200 and during the process of driving the bracket 302 in the connecting frame 300 to move in the direction towards the driving assembly 200 by the first connecting rod 301, since the bracket 302 in the connecting frame 300 no longer exerts a force on the rotating rod 303 towards the auxiliary antenna body 400, and thus the rotating rod 303 no longer exerts a force on the auxiliary antenna body 400, the elastic element 104 can simultaneously release the stored elastic force to drive the auxiliary antenna body 400 to move in the direction towards the driving assembly 200, that is, it can drive the auxiliary antenna body 400 to move in the direction away from the main antenna 010, so that the auxiliary antenna body 400 is separated from the main antenna 010. Moreover, the auxiliary antenna body 400 moving in the direction towards the driving assembly 200 can drive the rotating rod 303 to rotate in the direction towards the driving assembly 200 through its abutment with the second end of the rotating rod 303, so that the rotating rod 303 can move in the direction towards the driving assembly 200 while abutting against the bracket 302.

[0071] In summary, the embodiment of the present application provides an auxiliary antenna component, including: a support frame, a driving assembly, a connecting frame, and an auxiliary antenna body. After the driving assembly drives the auxiliary antenna body to move axially in the connecting frame and the auxiliary antenna body is lapped with the main antenna, the auxiliary antenna body can extend the length of the main antenna. In this way, the main antenna can transmit or receive radio signals with frequencies adapted to its extended length at the extended length. Similarly, after the auxiliary antenna body is separated from the main antenna, the main antenna can transmit or receive radio signals with frequencies adapted to its original length at the original length. Therefore, by means of this auxiliary antenna component, the length of the main antenna can be changed, so that main antennas with different lengths can transmit or receive radio signals with different frequencies, and it is ensured that the main antenna can transmit or receive different frequency radio signals with the highest transmission or reception efficiency.

[0072] The embodiment of the present application also provides an electronic device, which can be a mobile phone, a computer, a tablet computer, etc. Please refer to Figure 10 , Figure 10It is a schematic structural diagram of an electronic device provided by an embodiment of the present application. The electronic device 030 may include a housing 031, and an auxiliary antenna component and a main antenna 010 installed in the housing 031. The auxiliary antenna component in the electronic device 030 may be the auxiliary antenna component 000 in the above embodiment. By means of the auxiliary antenna component 000 in the electronic device 030, the length of the main antenna 010 in the electronic device 030 can be changed, so that the main antenna 010 in the electronic device 030 can emit or receive radio signals of different frequencies with the highest transmission or reception efficiency, and further, there is no need to provide main antennas of different lengths adapted to radio signals of different frequencies in the housing 021 of the electronic device 030, reducing the occupied space of the antenna in the electronic device 030, and thus reducing the volume of the electronic device 030.

[0073] It should be noted that the housing 031 in the electronic device 030 may be a metal housing. In this way, the housing 031 in the electronic device 030 can serve as the main antenna 010 in the electronic device 030.
