Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] In related technologies, electronic devices usually have multiple antennas to meet the needs of electronic devices for signals of different frequencies. However, as the number of antennas increases, the spatial layout of the antennas gradually becomes complicated. The internal space of mobile phones is limited, resulting in a poor spatial environment for the antennas, which affects the radiation performance of each antenna. Summary of the Invention

[0003] The present application aims to provide an electronic device that can solve the technical problem in the related art of setting multiple antennas in an electronic device, resulting in poor radiation performance of the antenna.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application provides an electronic device, comprising:

[0006] frame;

[0007] A first antenna is provided on the frame;

[0008] an elastic member, one end of which is connected to the first antenna, and the elastic member is conductive;

[0009] a second antenna, the second antenna being connected to the other end of the elastic member;

[0010] The driving mechanism drives the second antenna to change the distance between the first antenna and the second antenna.

[0011] In an embodiment of the present application, an electronic device includes a frame, a first antenna, an elastic member, a second antenna and a driving mechanism, one end of the elastic member is connected to the first antenna, and the other end of the elastic member is connected to the second antenna, and the elastic member is conductive, that is, the first antenna and the second antenna are electrically connected through the elastic member, and then the first antenna, the elastic member and the second antenna form an antenna system, wherein the first antenna is fixed on the frame, the second antenna and the frame can move relative to each other, and then the distance between the second antenna and the first antenna is variable, and the driving mechanism can drive the second antenna to move, thereby changing the distance between the first antenna and the second antenna, changing the overall length of the first antenna, the elastic member and the second antenna, and changing the reception strength of the antenna system formed by the first antenna, the elastic member and the second antenna for signals of different frequencies.

[0012] Specifically, under the action of the driving mechanism, the second antenna can be in a first position and a second position. When the second antenna is in the first position, the distance between the second antenna and the first antenna is the first distance. When the second antenna is in the second position, the distance between the second antenna and the first antenna is the second distance. The first distance is smaller than the second distance. When the second antenna is in the first position, the antenna assembly mainly receives high-frequency signals. When the second antenna is in the second position, the antenna assembly mainly receives low-frequency signals. Thus, the main receiving frequency of the electronic device is changed by changing the length between the first antenna, the elastic member and the second antenna. There is no need to set up multiple antenna assemblies, which saves space occupied by the antenna system in the electronic device and improves the radiation performance of the antenna system.

[0040] The electronic device 100 provided in the embodiment of the present application is described below through specific embodiments and application scenarios with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 13As shown, in some embodiments of the present application, the present application provides an electronic device 100, including: a frame 110; a first antenna 120, which is arranged on the frame 110; an elastic member 130, one end of the elastic member 130 is connected to the first antenna 120, and the elastic member 130 is conductive; a second antenna 140, the second antenna 140 is connected to the other end of the elastic member 130; and a driving mechanism 150, which drives the second antenna 140 to change the distance between the first antenna 120 and the second antenna 140.

[0042] In the embodiment of the present application, the electronic device 100 includes a frame 110, a first antenna 120, an elastic member 130, a second antenna 140 and a driving mechanism 150, one end of the elastic member 130 is connected to the first antenna 120, and the other end of the elastic member 130 is connected to the second antenna 140, and the elastic member 130 is conductive, that is, the first antenna 120 and the second antenna 140 are electrically connected through the elastic member 130, and then the first antenna 120, the elastic member 130 and the second antenna 140 form an antenna system, wherein the first antenna 120 is fixed on the frame 110, the second antenna 140 and the frame 110 can move relative to each other, so that the distance between the second antenna 140 and the first antenna 120 can be changed, and the driving mechanism 150 can drive the second antenna 140 to move, thereby changing the distance between the first antenna 120 and the second antenna 140, changing the overall length of the first antenna 120, the elastic member 130 and the second antenna 140, and changing the reception strength of the antenna system formed by the first antenna 120, the elastic member 130 and the second antenna 140 for signals of different frequencies.

[0043] Specifically, under the action of the driving mechanism 150, the second antenna 140 can be in a first position and a second position. When the second antenna 140 is in the first position, the distance between the second antenna 140 and the first antenna 120 is the first distance. When the second antenna 140 is in the second position, the distance between the second antenna 140 and the first antenna 120 is the second distance. The first distance is smaller than the second distance. Therefore, when the second antenna 140 is in the first position, the antenna assembly mainly receives high-frequency signals. When the second antenna 140 is in the second position, the antenna assembly mainly receives low-frequency signals. Therefore, the main receiving frequency of the electronic device 100 is changed by changing the length between the first antenna 120, the elastic member 130 and the second antenna 140. There is no need to set up multiple antenna assemblies, which saves space occupied by the antenna system in the electronic device 100 and improves the radiation performance of the antenna system.

[0044] The frequency change may be a change between 2.4G and 5G of a WiFi signal.

[0045] like Figure 4 and Figure 5As shown in the figure, as a possible embodiment, the second antenna 140 includes a protrusion 142, and the electronic device 100 further includes: a first channel 160; a second channel 162, the length of which is less than that of the first channel 160 and is farther away from the first antenna 120 than the first channel 160; and a third channel 164, one end of which is connected to the first channel 160 and the other end of which is connected to the second channel 162. The driving mechanism 150 moves the protrusion 142 between the first channel 160 and the second channel 162 by changing the position of the second antenna 140. In other words, the first channel 160, the second channel 162, and the third channel 164 form a limiting channel 158.

[0046] Specifically, the second antenna 140 includes a protrusion 142, and the electronic device 100 also includes a first channel 160, a second channel 162, and a third channel 164 that are connected, that is, one end of the third channel 164 is connected to the first channel 160, and the other end of the third channel 164 is connected to the second channel 162, and the length of the first channel 160 is greater than the length of the second channel 162, and the side of the second channel 162 facing the first antenna 120 is farther away from the first antenna 120 than the side of the first channel 160 facing the first channel 160. The driving mechanism 150 can drive the second antenna 140 to move, so that the protrusion 142 switches positions between the first channel 160, the third channel 164, and the second channel 162. Furthermore, when the protrusion 142 is located in the first channel 160 and the driving mechanism 150 stops driving the second antenna 140, the second antenna 140, under the action of the elastic member 130, the protrusion 142 and the first channel 160 are offset against each other on the side facing the first antenna 120, so that the distance between the second antenna 140 and the first antenna 120 is specifically the first distance. When the protrusion 142 is located in the second channel 162 and the driving mechanism 150 stops driving the second antenna 140, the second antenna 140, under the action of the elastic member 130, the protrusion 142 and the second channel 162 are offset against each other on the side facing the first antenna 120, so that the distance between the second antenna 140 and the first antenna 120 is specifically the second distance.

[0047] Furthermore, the antenna protrusion 142 and the first channel 160 , the second channel 162 and the third channel 164 of the electronic device 100 can limit the running track of the second antenna 140 , thereby ensuring the reliability of the switching length of the antenna system.

[0048] Among them, the ends of the first channel 160 and the second channel 162 facing away from the third channel 164 are both in a closed state. When the protrusion 142 is in the first position, the protrusion 142 and the channel side wall of the first channel 160 are against each other. When the protrusion 142 is in the second position, the protrusion 142 and the channel side wall of the second channel 162 are against each other.

[0049] like Figure 4 and Figure 5 As shown, as a possible implementation, it further includes: a limiting sleeve 152 provided on the frame 110 , the second antenna 140 passing through the limiting sleeve 152 , and the first channel 160 , the second channel 162 and the third channel 164 provided on the limiting sleeve 152 .

[0050] Specifically, the electronic device 100 also includes a limiting sleeve 152, and the first channel 160, the second channel 162 and the third channel 164 are arranged on the limiting sleeve 152, and the second antenna 140 is also inserted into the limiting sleeve 152, so that the second antenna 140 can move in the limiting sleeve 152, thereby improving the restriction on the second antenna 140, reducing the possibility of the protrusion 142 detaching from the first channel 160, the second channel 162 and the third channel 164, and improving the reliability of switching the main operating frequency of the antenna system.

[0051] Among them, such as Figure 4 As shown, the first channel 160, the second channel 162, and the third channel 164 are interconnected. The third channel 164 is interconnected with the end of the first channel 160 facing away from the first antenna 120, and the third channel 164 is interconnected with the end of the second channel 162 facing away from the first antenna 120. Furthermore, the ends of the first channel 160 and the second channel 162 facing away from the third channel 164 are both closed. When the protrusion 142 is in the first position, the protrusion 142 abuts against the sidewall of the first channel 160. When the protrusion 142 is in the second position, the protrusion 142 abuts against the sidewall of the second channel 162.

[0052] like Figure 5 As shown, the first channel 160, the second channel 162, and the third channel 164 are interconnected. The third channel 164 is interconnected with the end of the first channel 160 facing away from the first antenna 120, and the third channel 164 is interconnected with the end of the second channel 162 facing away from the first antenna 120. Furthermore, the end of the second channel 162 facing away from the third channel 164 is closed, while the end of the first channel 160 facing away from the third channel 164 is open. When the protrusion 142 is in the first position, the second antenna 140 is supported by the elastic member 130. When the protrusion 142 is in the second position, the protrusion 142 and the sidewall of the second channel 162 abut against each other.

[0053] like Figure 2 and Figure 3As shown, as a possible embodiment, the driving mechanism 150 includes: a first electromagnet 154, which is arranged on the side of the second antenna 140 away from the first antenna 120, and the first electromagnet 154 and the first channel 160 are arranged correspondingly; a second electromagnet 156, which is arranged on the side of the second antenna 140 away from the first antenna 120, and the second electromagnet 156 and the second channel 162 are arranged correspondingly.

[0054] Specifically, the driving mechanism 150 includes a first electromagnet 154 and a second electromagnet 156, and both electromagnets are arranged on the side of the second antenna 140 away from the first antenna 120, and the two electromagnets are arranged side by side, with the first electromagnet 154 corresponding to the first channel 160, and the second electromagnet 156 corresponding to the second channel 162.

[0055] like Figure 6 As shown, if the second antenna 140 is in the second position, that is, the protrusion 142 and the second channel 162 are matched, at this time, the overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is longer, which is used to receive signals with lower frequencies. When the frequency of the antenna system needs to be switched, the first electromagnet 154 works to generate a magnetic force to attract the second antenna 140 to move toward the side away from the first antenna 120, and the protrusion 142 moves along the second channel 162. After moving to a specific position, as shown in FIG. Figure 7 As shown, the protrusion 142 enters the third channel 164 and moves to a position corresponding to the first channel 160 under the action of the first electromagnet 154, that is, the protrusion 142 is located in the third channel 164 and corresponds to the first channel 160, as shown in FIG. Figure 8 As shown, at this point, the first electromagnet 154 stops working, and the second antenna 140 is no longer attracted. Consequently, under the action of the elastic member 130, the second antenna 140 moves toward the first antenna 120, causing the protrusion 142 to engage with the first channel 160, thereby placing the second antenna 140 in the first position. At this point, the overall length of the first antenna 120, elastic member 130, and second antenna 140 is relatively short, allowing it to receive higher-frequency signals. The terms "lower" and "higher" are relative, not absolute.

[0056] like Figure 9 As shown, if the second antenna 140 is in the first position, that is, the protrusion 142 and the first channel 160 are matched, at this time, the overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is relatively short, and is used to receive higher frequency signals. When the frequency of the antenna system needs to be switched, the second electromagnet 156 works to generate a magnetic force, attracting the second antenna 140 to move toward the side away from the first antenna 120, and the protrusion 142 moves along the first channel 160. After moving to a specific position, as shown in FIG. Figure 10As shown, the protrusion 142 enters the third channel 164 and moves to a position corresponding to the second channel 162 under the action of the second electromagnet 156, that is, the protrusion 142 is located in the third channel 164 and corresponds to the second channel 162, as shown in FIG. Figure 11 As shown, at this point, the second electromagnet 156 stops working, and the second antenna 140 is no longer attracted. Consequently, under the action of the elastic member 130, it moves toward the first antenna 120, causing the protrusion 142 to engage with the second channel 162, thereby placing the second antenna 140 in the second position. At this point, the overall length of the first antenna 120, the elastic member 130, and the second antenna 140 is longer, allowing it to receive lower-frequency signals. The terms "lower" and "higher" are relative, not absolute.

[0057] As described above, the second antenna 140 can be moved to the first position or the second position by the action of the first electromagnet 154 and the second electromagnet 156 , thereby changing the lengths of the first antenna 120 , the elastic member 130 and the second antenna 140 .

[0058] like Figure 12 As shown, as a possible implementation, it also includes: a first processor 190, which is electrically connected to the first antenna 120, the first electromagnet 154 and the second electromagnet 156. After the first electromagnet 154 or the second electromagnet 156 works, the first processor 190 determines the stopping time of the first electromagnet 154 or the second electromagnet 156 based on the signal strength.

[0059] Specifically, the electronic device 100 also includes a first processor 190, which is electrically connected to the first antenna 120, the first electromagnet 154, and the second electromagnet 156. After the first electromagnet 154 works, the first processor 190 determines the stopping time of the first electromagnet 154 based on the signal strength of the antenna system. After the second electromagnet 156 works, the first processor 190 determines the stopping time of the second electromagnet 156 based on the signal strength of the antenna system.

[0060] Specifically, Figure 18 FIG. 1 shows one of the flow charts for switching the position of the second antenna 140 in the electronic device 100 according to an embodiment of the present application. Figure 18 As shown, the method includes:

[0061] Step 1802: Based on the situation where the operating frequency of the antenna system needs to be switched;

[0062] Step 1804: The first electromagnet or the second electromagnet is energized to generate a magnetic field, and the second antenna moves due to the magnetic force;

[0063] Step 1806: Detecting the power-on time of the first electromagnet or the second electromagnet and the signal strength of the antenna system;

[0064] Step 1808: Detecting that the signal strength changes to the strongest state;

[0065] Step 1810: The first electromagnet or the second electromagnet is powered off.

[0066] The power-on duration can indicate the approximate location of the second antenna 140 , and combined with the antenna signal strength, can ensure that the second antenna 140 moves to a specific location.

[0067] Specifically, if the second antenna 140 is in the second position, that is, the protrusion 142 cooperates with the second channel 162, at this time, the overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is longer, and is used to receive signals with lower frequencies. When the frequency of the antenna system needs to be switched, the first electromagnet 154 works to generate a magnetic force, attracting the second antenna 140 to move toward the side away from the first antenna 120, and the protrusion 142 moves along the second channel 162. After moving to a specific position, the protrusion 142 enters the third channel 164 and moves to the first channel 164 under the action of the first electromagnet 154. 60, when the operating time of the first electromagnet 154 reaches the preset time and the signal strength of the antenna assembly reaches the strongest state, the protrusion 142 is located in the third channel 164 and corresponds to the first channel 160. At this time, the first electromagnet 154 stops working and the second antenna 140 is no longer attracted. Therefore, under the action of the elastic member 130, it moves toward the first antenna 120, so that the protrusion 142 and the first channel 160 cooperate, so that the second antenna 140 is in the first position. At this time, the overall length of the first antenna 120, the elastic member 130, and the second antenna 140 is shorter, which is used to receive higher frequency signals. Here, lower and higher are relative, not absolute.

[0068] If the second antenna 140 is in the first position, that is, the protrusion 142 and the first channel 160 are matched, at this time, the overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is relatively short, and is used to receive a signal with a higher frequency. When it is necessary to switch the frequency of the antenna system, the second electromagnet 156 works to generate a magnetic force, attracting the second antenna 140 to move toward the side away from the first antenna 120, and the protrusion 142 moves along the first channel 160. After moving to a specific position, the protrusion 142 enters the third channel 164 and moves to the second channel 162 under the action of the second electromagnet 156. At the corresponding position, when the second electromagnet 156 has operated for a predetermined period of time and the antenna assembly's signal strength has reached its strongest state, the raised portion 142 is located in the third channel 164 and corresponds to the second channel 162. At this point, the second electromagnet 156 stops operating, and the second antenna 140 is no longer attracted. Consequently, under the action of the elastic member 130, the second antenna 140 moves toward the first antenna 120, causing the raised portion 142 to engage with the second channel 162, thereby placing the second antenna 140 in the second position. At this point, the overall length of the first antenna 120, the elastic member 130, and the second antenna 140 is longer, allowing it to receive lower-frequency signals. The terms "lower" and "higher" are relative, not absolute.

[0069] like Figure 3 As shown, as a possible implementation, the first electromagnet 154 and the second electromagnet 156 are stacked on the frame 110 .

[0070] Specifically, the first electromagnet 154 and the second electromagnet 156 are stacked at intervals along the direction from close to the frame 110 to away from the frame 110. The first electromagnet 154 is close to the frame 110, that is, the first channel 160 is close to the frame 110, and the second electromagnet 156 is away from the frame 110, that is, the second channel 162 is away from the frame 110. Of course, the positions of the first electromagnet 154 and the second electromagnet 156 can be reversed, and the first channel 160 and the second channel 162 can also be reversed.

[0071] Furthermore, by utilizing the thickness direction of the electronic device 100 , two electromagnets are provided to reduce the lateral space occupied by the electronic device 100 , save space, and provide more installation space for other components such as the circuit board 180 .

[0072] like Figure 4 and Figure 5 As shown, as a possible implementation, the first channel 160 and the second channel 162 are arranged in parallel.

[0073] Specifically, the first channel 160 and the second channel 162 are arranged in parallel, so that the protrusion 142 can move smoothly in the first channel 160, the second channel 162 and the third channel 164, wherein the first channel 160 faces the first electromagnet 154 and the second channel 162 faces the second electromagnet 156.

[0074] like Figure 14 and Figure 15 As shown, as a possible implementation, the driving mechanism 150 includes: a motor 166 ; a gear 168 disposed on the output shaft of the motor 166 ; and a rack 170 meshing with the gear 168 and connected to the second antenna 140 .

[0075] Specifically, the driving mechanism 150 includes: a motor 166, a gear 168 and a rack 170. The rack 170 is connected to the second gear 168. The motor 166 is located on the side of the second antenna 140 away from the first antenna 120. The gear 168 is set on the output shaft of the motor 166. The gear 168 and the rack 170 are engaged with each other, and then the operation of the motor 166 drives the gear 168 to rotate, driving the rack 170 and the second antenna 140 to move, thereby changing the length of the first antenna 120, the elastic member 130 and the second antenna 140. This driving method has a simple structure and a stable operation effect.

[0076] Specifically, if Figure 14 As shown, the rack 170, driven by the motor 166 and the gear 168, pushes the second antenna 140 to the first position, so that the second antenna 140 is close to the first antenna 120. The overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is shorter. At this time, the antenna assembly is used to receive high-frequency signals.

[0077] like Figure 15 As shown, the rack 170, driven by the motor 166 and the gear 168, pushes the second antenna 140 to the second position, so that the second antenna 140 is away from the first antenna 120. The overall length of the first antenna 120, the elastic member 130 and the second antenna 140 is longer. At this time, the antenna assembly is used to receive low-frequency signals.

[0078] The gear 168 and the rack 170 can be made of plastic or plastic material.

[0079] like Figure 16 As shown, as a possible implementation, a slide groove 112 is provided on the frame 110 , and the second antenna 140 is disposed in the slide groove 112 .

[0080] Specifically, a slide groove 112 is provided on the frame, and the second antenna 140 is disposed in the slide groove 112 . Then, the motor 166 drives the second antenna 140 to move in the slide groove 112 , thereby providing a guide for the second antenna 140 and reducing the possibility of the second antenna 140 being offset.

[0081] like Figure 17 As shown, as a possible implementation, it further includes: a second processor 192 electrically connected to the first antenna 120 and the motor 166. After the motor 166 starts working, the second processor 192 determines the stopping time of the motor 166 according to the signal strength.

[0082] Specifically, the electronic device 100 further includes a second processor 192 , which is electrically connected to the first antenna 120 and the motor 166 . After the motor 166 starts working, the second processor 192 determines when to stop the motor 166 based on the signal strength of the antenna system.

[0083] Specifically, Figure 19 FIG. 2 shows a second flow chart of switching the position of the second antenna 140 in the electronic device 100 according to an embodiment of the present application. Figure 19 As shown, the method includes:

[0084] Step 1902: Based on the situation where the operating frequency of the antenna system needs to be switched;

[0085] Step 1904: The motor rotates to drive the second antenna toward or away from the first antenna;

[0086] Step 1906: Detect antenna system signal strength;

[0087] Step 1908: Detecting that the signal strength changes to the strongest state;

[0088] Step 1910: The motor stops rotating.

[0089] Specifically, if the second antenna 140 is currently in the first position and it is desired to switch the second antenna 140 from the first position to the second position, the motor 166 is controlled to operate so that the second antenna 140 moves in a direction away from the first antenna 120. When the signal strength of the antenna assembly reaches the strongest state, the motor 166 stops operating, and the second antenna 140 is now in the second position.

[0090] If the second antenna 140 is currently in the second position and it is desired to switch the second antenna 140 from the second position to the first position, the motor 166 is controlled to operate so that the second antenna 140 moves toward the first antenna 120. When the signal strength of the antenna assembly reaches the strongest state, the motor 166 stops operating, and the second antenna 140 is now in the first position.

[0091] As a possible implementation, a circuit board 180 is provided on the frame 110, the first electromagnet 154 and the second electromagnet 156 are electrically connected to the circuit board 180, and the motor 166 is electrically connected to the circuit board 180. The first antenna 120 is also electrically connected to the mainboard of the electronic device 100.

[0092] The electronic device 100 may be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device 100, a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. It may also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), an ATM, or an automated machine, etc., and the embodiments of the present application do not specifically limit this.
