Description

[0001] This application is a divisional application based on application number 202210157230.3, filed on February 21, 2022, entitled "An Antenna Slot Structure and Electronic Device". The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, and in particular to an antenna slot mechanism and electronic device. Background Technology

[0003] Currently, electronic devices can support mobile communication functions such as 2G, 3G, 4G, and 5G, and / or wireless communication functions such as Wireless Local Area Networks (WLAN), Bluetooth (BT), Global Navigation Satellite System (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), and Infrared (IR). To achieve the above communication functions, electronic devices need to be equipped with corresponding antennas.

[0004] Electronic devices typically have antenna slots along the metal frame of their casing. Multiple antenna slots can be installed, with the antenna positioned close to them. These slots provide a channel for the antenna to transmit or receive signals. Furthermore, to improve the airtightness of the electronic device and ensure its dust and water resistance, insulating plastic is usually filled into the antenna slots, and this insulating plastic is tightly bonded to the metal frame at the antenna slot.

[0005] However, during the assembly and manufacturing process of electronic devices, they may be bent or squeezed, and during user use, they may also be bent, squeezed, or dropped. These situations may cause the insulating plastic filling the antenna seams to lose its tight bond with the metal frame, thus compromising the airtightness of the electronic device and reducing its dustproof and waterproof capabilities. Summary of the Invention

[0006] To address the aforementioned issues, this application provides an antenna slot mechanism and electronic device that improves the bonding strength between the insulating plastic and the metal frame at the antenna slot, enhances the airtightness of the electronic device, and thus ensures the dustproof and waterproof capabilities of the electronic device.

[0007] In a first aspect, this application provides an antenna slot structure for use in electronic devices equipped with antennas. The antenna slot structure includes insulating plastic and a metal frame. The metal frame is divided into a first portion and a second portion by the antenna slot. The first portion and / or the second portion has a first groove at the antenna slot. The first groove extends from the antenna slot away from it. The insulating plastic fills the first groove and the antenna slot.

[0008] The antenna slot is essentially a break, with the cross-sections of the first and second parts facing each other. When the first part has a first groove, the opening of the first groove starts from the antenna slot and extends along the first part in a direction away from the antenna slot, with the opening of the first groove located on the corresponding cross-section of the first part. When the second part has a first groove, the opening of the first groove starts from the antenna slot and extends along the second part in a direction away from the antenna slot, with the opening of the first groove located on the corresponding cross-section of the second part. Filling both the first groove and the antenna slot with insulating plastic increases the contact area between the insulating plastic and the metal frame, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. It also increases the thickness of the insulating plastic at the first groove, reducing the likelihood of cracking when the antenna slot structure is bent, squeezed, or dropped. This enhances the airtightness of the electronic device, thus ensuring its dustproof and waterproof capabilities.

[0009] In one possible implementation, the concave surface of the first groove may include milled grooves and / or laser engraving to further enhance the stability and bonding strength of the connection between the metal frame and the insulating plastic. By providing milled grooves or laser engraving on the concave surface of the first groove, the contact area between the insulating plastic and the metal frame is further increased, further enhancing the stability and bonding strength of the connection between the insulating plastic and the metal frame. This makes it less likely for the insulating plastic and the metal frame at the concave surface of the first groove to move relative to each other when the antenna slot structure is bent, squeezed, or dropped. Therefore, it reduces the probability of cracking in the connection between the insulating plastic and the metal frame at the concave surface of the first groove, enhances the airtightness of the electronic device, and further ensures the dustproof and waterproof capabilities of the electronic device.

[0010] In one possible implementation, the metal frame includes a first side and a second side connected in sequence, with a first groove located on the first side. At least a portion of the first and second portions is further provided with one or more second grooves on the second side. Insulating plastic covers the first and second sides and fills the one or more second grooves.

[0011] After filling both the second groove and the antenna slot with insulating plastic, the contact area between the insulating plastic and the metal frame is increased, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. Furthermore, the second groove structure has a limiting effect on the insulating plastic and also increases the thickness of the insulating plastic, which reduces the possibility of cracking when the antenna slot structure is bent, squeezed, or dropped. Therefore, it enhances the airtightness of the electronic device and ensures its dustproof and waterproof capabilities.

[0012] In one possible implementation, at least a portion of the first part and the second part has a second groove on the second side. The second groove extends to the first side; the opening of the second groove on the first side is entirely located on the concave surface of the first groove, or the opening of the second groove on the first side is partially located on the concave surface of the first groove.

[0013] In one possible implementation, at least one of the first and second portions has a plurality of second grooves on the second side; the plurality of second grooves extend to the first side; one of the plurality of second grooves has its opening on the first side partially located on the concave surface of the first groove. The plurality of second grooves includes at least one second groove whose opening on the first side is located outside the first groove.

[0014] In one possible implementation, the plurality of second grooves further includes at least one second groove, wherein the opening on the first side is entirely located on the concave surface of the first groove.

[0015] In one possible implementation, the concave surface of one or more second grooves includes at least one of the following: milled grooves or laser engraving. By providing milled grooves or laser engraving on the concave surface of the second groove, the contact area between the insulating plastic and the metal frame is further increased, improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. This makes it less likely for the insulating plastic at the concave surface of the second groove and the metal frame to move relative to each other when the antenna slot structure is bent, squeezed, or dropped, thus reducing the probability of cracking of the insulating plastic at the concave surface of the second groove, enhancing the airtightness of the electronic device, and further ensuring the dustproof and waterproof capabilities of the electronic device.

[0016] In one possible implementation, one or more second grooves include at least one of the following: through groove or blind groove.

[0017] In one possible implementation, both the first portion and the second portion include the second groove, and the number of the second grooves included in the first portion is equal to the number of the second grooves included in the second portion.

[0018] In one possible implementation, both the first portion and the second portion include the first groove, and the number of the first grooves included in the first portion is equal to the number of the first grooves included in the second portion.

[0019] Secondly, this application also provides an antenna slot structure, which includes insulating plastic and a metal frame. The metal frame includes a first portion and a second portion, which are separated to form an antenna slot. The metal frame includes a first side and a second side connected in sequence. At least a portion of the first portion and the second portion has one or more second grooves provided on the second side. The insulating plastic covers the first side and the second side and fills the antenna slot and the one or more second grooves.

[0020] This design, by filling both the second groove and the antenna slot with insulating plastic, increases the contact area between the insulating plastic and the metal frame, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. Furthermore, the second groove structure acts as a limit for the insulating plastic and increases its thickness, reducing the likelihood of cracking when the antenna slot structure is bent, squeezed, or dropped. This enhances the airtightness of the electronic device, thus ensuring its dustproof and waterproof capabilities.

[0021] In one possible implementation, at least a portion of the first part and the second part has a first groove at the antenna slot; the first groove is located on the first side; the first groove starts from the antenna slot and extends in a direction away from the antenna slot; the first groove is filled with insulating plastic.

[0022] In one possible implementation, the concave surface of the first groove includes at least one of the following: milling or laser engraving.

[0023] In one possible implementation, at least a portion of the first part and the second part has a second groove on the second side; the second groove extends to the first side; the opening of the second groove on the first side is entirely located on the concave surface of the first groove, or the opening of the second groove on the first side is partially located on the concave surface of the first groove.

[0024] In one possible implementation, at least one of the first part and the second part has a plurality of second grooves on the second side; the plurality of second grooves extend to the first side; one of the plurality of second grooves has its opening on the first side partially located on the concave surface of the first groove; the plurality of second grooves includes at least one second groove whose opening on the first side is located outside the first groove.

[0025] In one possible implementation, the plurality of second grooves further includes at least one second groove, with the opening on the first side entirely located on the concave surface of the first groove.

[0026] In one possible implementation, the concave surface of one or more second grooves includes at least one of the following: milling or laser engraving.

[0027] In one possible implementation, one or more second grooves include at least one of the following: through groove or blind groove.

[0028] Thirdly, this application also provides an electronic device that can be a mobile phone, laptop computer, wearable electronic device (such as a smartwatch), tablet computer, or other electronic device equipped with an antenna. This electronic device includes one or more antenna slot structures provided in the above implementations.

[0029] Because the antenna slot structure of this electronic device incorporates a first groove and / or a second groove, and insulating plastic is filled in both the groove and the antenna slot, the contact area between the insulating plastic and the metal frame is increased, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. Specifically, filling the first groove with insulating plastic increases the thickness of the insulating plastic near the antenna slot, reducing the probability of breakage. The second groove structure provides restraint and locking for the insulating plastic, reducing the likelihood of cracking in the antenna slot structure under bending, compression, or drop conditions. This enhances the airtightness of the electronic device, thus ensuring its dustproof and waterproof capabilities.

[0030] In one possible implementation, the electronic device includes multiple antenna slot structures, and further includes a first short side, a first long side, a second short side, and a second long side connected in sequence. The multiple antenna slot structures include a first group of antenna slot structures and a second group of antenna slot structures; the first group of antenna slot structures is located on the first long side; the second group of antenna slot structures is located on the second long side.

[0031] In one possible implementation, the multiple antenna slot structures also include a third group of antenna slot structures and a fourth group of antenna slot structures; the third group of antenna slot structures is located on the first short side; and the fourth group of antenna slot structures is located on the second short side.

[0064] To enable those skilled in the art to better understand the solution of this application, the application scenario of the technical solution of this application will be described first below.

[0065] The solution provided in this application is applied to electronic devices equipped with antennas. This application does not specifically limit the type of electronic device. The electronic device can be a mobile phone, a laptop, a wearable electronic device (such as a smartwatch), a tablet computer, an augmented reality (AR) device, a virtual reality (VR) device, and an in-vehicle device, etc. The structure of the electronic device is illustrated below.

[0066] The communication function of electronic devices is realized through antenna arrays, mobile communication modules, wireless communication modules, modem processors, and baseband processors.

[0067] An antenna array typically includes multiple antennas to enable mobile and wireless communication functions. Specifically, the antenna array transmits and receives electromagnetic wave signals. Each antenna in an electronic device can cover one or more communication frequency bands. Different antennas can also be reused to improve antenna utilization. For example, one antenna in an antenna array can be reused as a diversity antenna for a wireless local area network. In some other embodiments, the antenna can be used in conjunction with a tuning switch.

[0068] Mobile communication modules can provide solutions for wireless communication applications, including 2G, 3G, 4G, and 5G, in electronic devices. A mobile communication module may include at least one filter, switch, power amplifier, low-noise amplifier (LNA), etc. The mobile communication module can receive electromagnetic waves through an antenna in an antenna array, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation. The mobile communication module can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation through the antenna in the antenna array. In some embodiments, at least some functional modules of the mobile communication module may be housed within a processor. In some embodiments, at least some functional modules of the mobile communication module and at least some modules of the processor may be housed in the same device.

[0069] A modem processor may include a modulator and a demodulator. The modulator modulates a low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates a received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to a baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to an application processor. The application processor outputs sound signals through an audio device (not limited to a speaker, receiver, etc.) or displays images or videos on a display screen. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor and housed within the same device as a mobile communication module or other functional modules.

[0070] Wireless communication modules can provide solutions for wireless communication applications in electronic devices, including Wireless Local Area Networks (WLANs) (such as Wi-Fi networks), Bluetooth (BT), Global Navigation Satellite System (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), and Infrared (IR) technologies. A wireless communication module can be one or more devices integrating at least one communication processing module. The wireless communication module receives electromagnetic waves via an antenna in an antenna array, modulates and filters the electromagnetic wave signal, and sends the processed signal to a processor. The wireless communication module can also receive signals to be transmitted from the processor, modulate and amplify them, and then convert them into electromagnetic waves for radiation via the antenna in the antenna array.

[0071] In some embodiments, wireless communication technologies may include Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time-Division Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technologies. The GNSS may include Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), BeiDou Navigation Satellite System (BDS), Quasi-Zenith Satellite System (QZSS), and / or Satellite Based Augmentation Systems (SBAS).

[0072] To strengthen the device's body and enhance its appearance and texture, electronic devices typically use a metal frame with antenna slots. Multiple antenna slots can be installed on the metal frame, and the antennas are positioned close to the slots, providing a channel for the antennas to transmit or receive signals.

[0073] On the other hand, the International Protection Marking (IEC 60529), also known as Ingress Protection Rating or IP Code, is sometimes referred to as "waterproof rating" or "dustproof rating." It defines the level of protection that mechanical and electronic equipment provides against the intrusion of solid foreign objects (including body parts such as fingers, dust, and grit), liquid penetration, and accidental contact. To improve the airtightness of electronic equipment and ensure its dustproof and waterproof capabilities, insulating plastic is typically used to fill the antenna seams, and this insulating plastic is tightly bonded to the frame of the antenna seam.

[0074] The following uses a mobile phone as an example to illustrate the implementation of the antenna slot structure. The implementation of other types of electronic devices is similar, and will not be repeated here.

[0075] See Figure 1 The image is a schematic diagram of a mobile phone.

[0076] Figure 1 The image shows the mobile phone, as well as side views of the phone to the left and right, and top and bottom views. Figure 1 The layout and number of antenna slot structures 20 set on the four sides of the frame are only one possible implementation.

[0077] See Figure 2 The figure shows a schematic diagram of the antenna slot structure.

[0078] The illustrated antenna slot structure includes a metal frame 21 and insulating plastic 23. The metal frame 21 includes an antenna slot 22, and the insulating plastic 23 fills the inside of the metal frame and the antenna slot 22.

[0079] During the assembly and manufacturing process of a mobile phone, it may be bent or squeezed, and during user use, it may also be bent, squeezed, or dropped. These situations may cause the insulating plastic 23 filling the antenna seam 20 to lose its tight bond with the metal frame 21, thus compromising the phone's airtightness and reducing its actual dustproof and waterproof capabilities. If the user continues to use the phone according to its theoretically corresponding international protection rating, it may damage the phone or even pose a safety hazard.

[0080] To address the above issues, this application provides an antenna slot structure and electronic device that improves the stability and bonding strength of the connection between the insulating plastic and the metal frame. This reduces the likelihood of cracking when the antenna slot structure is bent, squeezed, or dropped, thereby enhancing the airtightness of the electronic device and ensuring its dustproof and waterproof capabilities.

[0081] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0082] The terms "first" and "second" used in this application description are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0083] It is understood that the directional names such as "up", "down", "left", and "right" in the following embodiments of this application are only for ease of explanation and should be referred to the directions in the accompanying drawings, and do not constitute a limitation on the technical solution of this application.

[0084] See also Figure 3a , Figure 3b , Figure 4a , Figure 4b Figure c and Figure 5 .in, Figure 3a A schematic diagram of an antenna slot structure provided in an embodiment of this application; Figure 3b Provided for the embodiments of this application Figure 3a Corresponding exploded view; Figure 4a A schematic diagram of a metal frame for an antenna slot structure provided in an embodiment of this application; Figure 4b Provided for the embodiments of this application Figure 3a Illustrations of the corresponding metal frame from different viewing angles Figure 1 ; Figure 4c Provided for the embodiments of this application Figure 3a Illustrations of the corresponding metal frame from different viewing angles Figure 2 ; Figure 5 This is a schematic diagram of an insulating plastic for an antenna slot structure provided in an embodiment of this application.

[0085] The antenna slot structure includes a metal frame 21 and insulating plastic 23.

[0086] Figure 4 shows Figure 3a Top view of the metal frame 21 after the angle has been adjusted.

[0087] The metal frame includes a first part 211 and a second part 212, which are separated from each other to form an antenna slot 22. That is, the antenna slot 22 is equivalent to a break in the metal frame, dividing the metal frame into the first part 211 and the second part 212.

[0088] See Figure 4b The first part 211 forms a first cross-section S1 at the antenna slot 22, and the first cross-section S1 is the surface of the first part 211 adjacent to the antenna slot; see also Figure 4c The second part 212 forms a second cross section S2 at the antenna slot 22. The second cross section S2 is also the surface of the second part 202 adjacent to the antenna slot. The first cross section S1 and the second cross section S2 are opposite to each other.

[0089] At least a portion of the first part 211 and the second part 212 is provided with a first groove. In this embodiment of the application, the example is that both the first part 211 and the second part 212 are provided with a first groove. The implementation principle is similar when only a portion of the first part 211 and the second part 212 is provided with a first groove, and will not be described again here.

[0090] The first part 211 is provided with a first groove 2111. The groove 2111 extends from the antenna slot 22 along the first part 211 in a direction away from the antenna slot 22, which is also the direction to the left from the antenna slot 22 in Figure 4. The embodiments of this application do not specifically limit the width, length and depth of the first groove 2111.

[0091] The second part 212 is provided with a first groove 2121. The opening of the first groove 2121 starts from the antenna slot 22 and extends on the second part 212 in a direction away from the antenna slot 22, that is, it extends to the right from the antenna slot 22 in Figure 4. The embodiments of this application do not specifically limit the width, length and depth of the first groove 2121.

[0092] In practical applications, when both the first part 211 and the second part 212 are provided with a first groove, the first grooves on the first part 211 and the second part 212 are generally symmetrically distributed, and the parameters such as width, length and depth are the same.

[0093] See Figure 5 , Figure 5 The image shows the cured state of the insulating plastic. Figure 5 and Figure 3b From different perspectives. When the insulating plastic 23 fills the first groove and the antenna slot, the portion of the insulating plastic labeled 233 fills the antenna slot 22, the portion of the insulating plastic labeled 231 fills the first groove 2111, and the portion of the insulating plastic labeled 232 fills the first groove 2111.

[0094] above Figures 4a to 4c The shape of the first groove shown is only one possible implementation. In practical applications, the first groove can also take other shapes, such as rectangle, semicircle, triangle, etc.

[0095] The solution provided in this application increases the contact area between the insulating plastic and the metal frame after filling both the first groove and the antenna slot with insulating plastic. This improves the stability and bonding strength of the connection between the insulating plastic and the metal frame. Furthermore, when the insulating plastic is filled into the first groove, the thickness of the insulating plastic is also increased, reducing the possibility of cracking when the antenna slot structure is bent, squeezed, or dropped. This enhances the airtightness of the electronic device and ensures its dustproof and waterproof capabilities.

[0096] In addition, milling grooves or laser engravings can be set in the first groove to further increase the contact area between the insulating plastic and the metal frame, thereby further improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. This will be explained in detail below with reference to the attached drawings.

[0097] See Figure 6 The figure is a schematic diagram of the metal frame of another antenna slot structure provided in an embodiment of this application.

[0098] Figure 6 and Figure 4a The difference is that the milled grooves or laser engravings on the concave surfaces of the first grooves on the first part 211 and the second part 212 are marked with 213.

[0099] Here, a milled groove refers to a groove machined on a metal surface using a milling cutter. When a milled groove is provided on the concave surface of the first groove, the embodiments of this application do not specifically limit the number, width, and depth of the milled grooves.

[0100] Laser engraving refers to using a laser beam to carve a permanent mark on a metal surface. When laser engraving is applied to the concave surface of the first groove, the embodiments of this application do not specifically limit the number, width, and depth of the laser engraving.

[0101] By setting milled grooves or laser engravings on the concave surface of the first groove, the contact area between the insulating plastic and the metal frame is further increased, which further improves the stability and bonding strength of the connection between the insulating plastic and the metal frame. This makes it less likely for the insulating plastic and the metal frame to move relative to each other when the antenna slot structure is bent, squeezed, or dropped. Therefore, it reduces the probability of cracking of the connection between the insulating plastic and the metal frame at the concave surface of the first groove, enhances the airtightness of the electronic device, and further ensures the dustproof and waterproof capabilities of the electronic device.

[0102] The following describes another way to implement the antenna slot structure.

[0103] See also Figure 7a , Figure 7b and Figure 8 .in, Figure 7a A schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application; Figure 7b Provided for the embodiments of this application Figure 7a A schematic diagram of the corresponding metal frame from another perspective; Figure 8 This is a schematic diagram of an insulating plastic for another antenna slot structure provided in an embodiment of this application.

[0104] The antenna slot structure includes a metal frame and insulating plastic 23.

[0105] The metal frame includes a first part 211 and a second part 212, which are separated from each other to form an antenna slot 22. That is, the antenna slot 22 is equivalent to a break in the metal frame, dividing the metal frame into the first part 211 and the second part 212.

[0106] The first part 211 forms a first cross-section at the antenna slot 22, and the second part 212 forms a second cross-section at the antenna slot 22. The first cross-section and the second cross-section are opposite to each other.

[0107] The metal frame includes a first side and a second side connected in sequence. Figure 7a and Figure 7b The first side is side A, and the second side is side B.

[0108] At least a portion of the first part 211 and the second part 212 is provided with one or more second grooves 214 on the second side. In this embodiment of the application, the first part 211 and the second part 212 are provided with two second grooves 214 as an example. The implementation principle is similar when only a portion of the first part 211 and the second part 212 are provided with second grooves 214, or when the number of second grooves 214 is other, and will not be described again here.

[0109] Figure 7a and Figure 7b The second groove 214 shown is a through groove, that is, the second groove 214 extends through the second side. Figure 7a and Figure 7b The second groove 214 shown is a semi-circular groove. The second groove 214 can also be a groove of other shapes, such as a rectangular groove, a triangular groove or a "T" shaped groove. In addition, the embodiments of this application do not specifically limit the width and depth of the second groove 214.

[0110] In addition, in some other embodiments, the second groove 214 may also be a blind groove, that is, the second groove 214 may not penetrate the second side.

[0111] In practical applications, when both the first part 211 and the second part 212 are provided with a second groove, the first grooves on the first part 211 and the second part 212 generally appear in pairs, and the parameters such as width, length and depth are the same, which means that the first part 211 and the second part 212 are symmetrical about the antenna slot, so as to facilitate processing and forming.

[0112] See Figure 8 , Figure 8 The cured state of the insulating plastic 23 is shown. The insulating plastic 23 covers the first and second sides and fills the antenna slot 22 and the second groove 214.

[0113] When the insulating plastic 23 fills the second groove and the antenna slot, the portion of the insulating plastic labeled 233 fills the antenna slot 22, and the portion of the insulating plastic labeled 234 fills the second groove 214.

[0114] The solution provided in this application increases the contact area between the insulating plastic and the metal frame after filling both the second groove and the antenna slot with insulating plastic. This improves the stability and bonding strength of the connection between the insulating plastic and the metal frame. Furthermore, the second groove structure has a limiting effect on the insulating plastic and increases the thickness of the insulating plastic. This reduces the possibility of cracking when the antenna slot structure is bent, squeezed, or dropped, thus enhancing the airtightness of the electronic device and ensuring its dustproof and waterproof capabilities.

[0115] In addition, milling grooves or laser engravings can be set in the second groove to further improve the stability and bonding strength of the connection between the insulating plastic and the metal frame. The following is a detailed explanation with reference to the attached drawings.

[0116] See Figure 9 The figure is a schematic diagram of the metal frame of another antenna slot structure provided in the embodiment of this application.

[0117] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0118] A milled groove refers to a groove machined on a metal surface using a milling cutter. When a milled groove is provided on the concave surface of the second groove, the embodiments of this application do not specifically limit the number, width, and depth of the milled grooves.

[0119] Laser engraving refers to using a laser beam to carve a permanent mark on a metal surface. When laser engraving is applied to the concave surface of the second groove, this application embodiment does not specifically limit the number, width, or depth of the laser engravings.

[0120] By setting milled grooves or laser engravings on the concave surface of the second groove, the contact area between the insulating plastic and the metal frame is further increased, improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. This makes it less likely for the insulating plastic and the metal frame to move relative to each other when the antenna slot structure is bent, squeezed, or dropped. Therefore, it reduces the probability of cracking of the insulating plastic on the concave surface of the second groove, enhances the airtightness of the electronic device, and further ensures the dustproof and waterproof capabilities of the electronic device.

[0121] The antenna slot structure provided in the above embodiments of this application includes a first groove or a second groove. The following describes the implementation method in which the antenna slot structure includes both a first groove and a second groove.

[0122] See also Figure 10a , Figure 10b and Figure 10c .in, Figure 10a A schematic diagram of the metal frame of another antenna slot structure provided in an embodiment of this application; Figure 10b Provided for the embodiments of this application Figure 10a Illustrations of the corresponding metal frame from different viewing angles Figure 1 ; Figure 10c Provided for the embodiments of this application Figure 10a Illustrations of the corresponding metal frame from different viewing angles Figure 2 .

[0123] The antenna slot structure includes a metal frame and insulating plastic.

[0124] The metal frame includes a first part 211 and a second part 212, which are separated from each other to form an antenna slot 22. That is, the antenna slot 22 is equivalent to a break in the metal frame, dividing the metal frame into the first part 211 and the second part 212.

[0125] See Figure 10b The first part 211 forms a first section S1 at the antenna slot 22; see also Figure 10c The second part 212 forms a second section S2 at the antenna slot 22. The first section S1 and the second section S2 are opposite to each other.

[0126] The metal frame includes a first side and a second side connected in sequence. Figures 10a to 10c The first side is side A, and the second side is side B.

[0127] At least a portion of the first part 211 and the second part 212 is provided with a first groove on a first side. In this embodiment of the application, the example is that both the first part 211 and the second part 212 are provided with the first groove. The implementation principle is similar when only a portion of the first part 211 and the second part 212 are provided with the first groove, and will not be described again here.

[0128] The first part 211 is provided with a first groove 2111, the opening of the first groove 2111 starting from the antenna slot 22 and extending on the first part 211 in a direction away from the antenna slot 22. Figure 10a The middle section extends to the left starting from antenna slot 22.

[0129] The second part 212 is provided with a first groove 2121. The groove 2121 starts from the antenna slot 22 and extends on the second part 212 in a direction away from the antenna slot 22. Figure 10a The middle section extends to the right starting from antenna slot 22.

[0130] At least a portion of the first part 211 and the second part 212 is provided with one or more second grooves 214 on the second side. In this embodiment of the application, the first part 211 and the second part 212 are provided with two second grooves 214 as an example. The implementation principle is similar when only a portion of the first part 211 and the second part 212 are provided with second grooves 214, or when the number of second grooves 214 is other, and will not be described again here.

[0131] The second groove 214 shown in Figure 10 is a through groove, that is, the second groove 214 extends through the second side. In addition, in another possible implementation, the second groove can also be a blind groove, that is, the second groove 214 may not extend through the second side.

[0132] The embodiments of this application do not specifically limit the width, length, and depth of each first and second groove. The first groove can also take other shapes, such as rectangular, semi-circular, or triangular. The second groove 214 can also take other shapes, such as rectangular, triangular, or "T" shaped grooves.

[0133] See Figure 11 The figure is a schematic diagram of an insulating plastic for another antenna slot structure provided in an embodiment of this application.

[0134] Figure 11 It shows Figures 10a to 10c The image shows the cured form of the insulating plastic 23 corresponding to the metal frame. The insulating plastic 23 covers the first and second sides and fills the antenna slots 22, each of the first grooves, and each of the second grooves.

[0135] When the insulating plastic 23 fills the first groove and the antenna slot, the portion of insulating plastic labeled 233 fills the antenna slot 22, the portion of insulating plastic labeled 231 fills the first groove 2111, the portion of insulating plastic labeled 232 fills the first groove 2111, and the portion of insulating plastic labeled 234 fills the second groove 214.

[0136] In the above embodiments, both the first part 211 and the second part 212 include a first groove, and the number of first grooves in the first part 211 is equal to the number of first grooves in the second part 212; both the first part 211 and the second part 212 include a second groove, and the number of second grooves in the first part 211 is equal to the number of second grooves in the second part 211, so that the antenna slot structure has good symmetry. In practical applications, the number of first grooves in the first part 211 and the second part 212 may also be different, and the number of second grooves in the first part 211 and the second part 212 may also be different. For example, the first part 211 includes two second grooves, and the second part 212 includes three second grooves.

[0137] The solution provided in this application increases the contact area between the insulating plastic and the metal frame by filling the antenna slot, each first groove, and each second groove with insulating plastic, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. Specifically, filling the first groove with insulating plastic increases the thickness of the insulating plastic near the antenna slot, reducing the probability of breakage. The second groove structure has a limiting and locking function for the insulating plastic and also increases the thickness of the insulating plastic in the second groove, reducing the possibility of cracking when the antenna slot structure is bent, squeezed, or dropped. Therefore, it enhances the airtightness of the electronic device, thereby ensuring the dustproof and waterproof capabilities of the electronic device.

[0138] In addition, milled grooves or laser engravings can be provided in the first and / or second grooves to further improve the stability and bonding strength of the connection between the insulating plastic and the metal frame. The following is a detailed explanation with reference to the attached drawings.

[0139] See also Figure 12a and Figure 12b .in, Figure 12a A schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application; Figure 12b Provided for the embodiments of this application Figure 12a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0140] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0141] By setting milled grooves or laser engravings on the concave surface of the second groove, the contact area between the insulating plastic and the metal frame is further increased, improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. This makes it less likely for the contact surface between the insulating plastic and the metal frame at the concave surface of the first groove to move relative to each other when the antenna slot structure is bent, squeezed, or dropped. Therefore, it reduces the probability of cracking of the insulating plastic at the concave surface of the first groove, enhances the airtightness of the electronic device, and further ensures the dustproof and waterproof capabilities of the electronic device.

[0142] See also Figure 13a and Figure 13b .in, Figure 13a A schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application; Figure 13b Provided for the embodiments of this application Figure 13a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0143] For the first groove on the first part 211 and the second part 212, the milled groove or laser engraving on its concave surface is marked by 213.

[0144] By setting milled grooves or laser engravings on the concave surface of the first groove, the contact area between the insulating plastic and the metal frame is further increased, improving the stability and bonding strength of the connection between the insulating plastic and the metal frame at the concave surface of the first groove. This makes it less likely for the insulating plastic and the metal frame to move relative to each other when the antenna slot structure is bent, squeezed, or dropped, thus reducing the probability of cracking of the insulating plastic at the concave surface of the first groove, enhancing the airtightness of the electronic device, and further ensuring the dustproof and waterproof capabilities of the electronic device.

[0145] See also Figure 14a and Figure 14b .in, Figure 14a A schematic diagram of the metal frame of another antenna slot structure provided in an embodiment of this application; Figure 14b Provided for the embodiments of this application Figure 14a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0146] For the first groove on the first part 211 and the second part 212, the milled groove or laser engraving on its concave surface is marked with 213. For the second groove 214 on the first part 211 and the second part 212, the milled groove or laser engraving on its concave surface is marked with 2141.

[0147] This design incorporates milled grooves or laser engravings on both the first and second grooves, increasing the stability and bonding strength of the connection between the insulating plastic and the metal frame at the concave surfaces of the first and second grooves. This prevents relative movement between the insulating plastic and the metal frame at the concave surfaces of the antenna slot structure when subjected to bending, compression, or drops, thus reducing the probability of cracking of the insulating plastic at the concave surfaces of the first and second grooves, enhancing the airtightness of the electronic device, and further ensuring its dustproof and waterproof capabilities.

[0148] In the above embodiments, for the two second grooves included in the first or second part of the antenna slot structure, the opening of one second groove on the first side is located outside the first groove, and the opening of the other second groove on the first side is located on the concave surface of the first groove.

[0149] The following describes other ways to realize the relative positional relationship between the first groove and the second groove when the antenna slot structure includes both the first groove and the second groove.

[0150] See also Figure 15a and Figure 15b .in, Figure 15aThis is a schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application. Figure 15b Provided for the embodiments of this application Figure 15a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0151] In this implementation, the first part 211 and the second part 212 each include two second grooves.

[0152] One end of each second groove extends to the first side, and the opening of each second groove on the first side is entirely located outside the groove surface of the first groove. Since the first and second grooves are physically separated from each other, they are easy to process.

[0153] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0154] See also Figure 16a and Figure 16b .in, Figure 16a A schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application; Figure 16b Provided for the embodiments of this application Figure 16a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0155] In this implementation, the first part 211 and the second part 212 each include two second grooves. The first part 211 and the second part 212 are symmetrical along the antenna slot 22. The following description takes the second groove included in the first part 211 as an example.

[0156] The first part 211 includes a second groove whose opening on the first side is completely inside the groove surface of the first groove, and another second groove included in the first part 211 has its opening on the first side completely outside the groove surface of the first groove.

[0157] When this implementation is adopted, since the slot of the second groove on the first side is completely located on the slot surface of the first groove, the size occupied by the second groove can be reduced. That is, when comparing the methods shown in Figure 16 and Figure 15, it can be found that the size of the antenna slot structure shown in Figure 16 is smaller when the same number of second grooves are set.

[0158] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0159] See also Figure 17a and Figure 17b .in, Figure 17a A schematic diagram of the metal frame of another antenna slot structure provided in an embodiment of this application; Figure 17b Provided for the embodiments of this application Figure 17a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0160] In this implementation, the first part 211 and the second part 212 each include three second grooves. The first part 211 and the second part 212 are symmetrical along the antenna slot 22. The following description takes the second groove included in the first part 211 as an example.

[0161] The first part 211 includes a second groove whose opening on the first side is completely located within the groove surface of the first groove. The first part 211 also includes a second groove whose opening on the first side is completely located outside the groove surface of the first groove. The first part 211 also includes a second groove whose opening on the first side is partially located outside the groove surface of the first groove and partially located within the groove surface of the first groove.

[0162] When this implementation is adopted, since the opening of the second groove on the first side is entirely located within the groove surface of the first groove, and the opening of the second groove on the first side is partially located within the groove surface of the first groove, the size occupied by the second groove can be reduced. In other words, when comparing the methods shown in Figure 17 and Figure 15, it can be found that although more second grooves are set in Figure 17, the size of the antenna slot structure shown in Figure 17 has not increased significantly.

[0163] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0164] See also Figure 18a and Figure 18b .in, Figure 18a This is a schematic diagram of a metal frame for another antenna slot structure provided in an embodiment of this application. Figure 18b Provided for the embodiments of this application Figure 18a Schematic diagrams of the corresponding metal frame from different viewing angles.

[0165] In this implementation, the first part 211 and the second part 212 each include a second groove. The opening of the second groove on the first side is entirely located on the concave surface of the first groove.

[0166] This implementation method can significantly reduce the size of the antenna slot structure.

[0167] In addition, in some other possible implementations, when the first part 211 and the second part 212 each include a second groove, the opening of the second groove on the first side can be entirely located on the concave surface of the first groove, or the opening of the second groove on the first side can be partially located on the concave surface of the first groove.

[0168] The milled grooves or laser engravings on the concave surfaces of the second grooves 214 on the first part 211 and the second part 212 are marked with 2141.

[0169] Based on the antenna slot structure provided in the above embodiments, this application also provides an electronic device, which is provided with an antenna and the antenna slot structure provided in the above embodiments. The following description takes a mobile phone as an example and is based on the accompanying drawings.

[0170] See Figure 19 This figure is a schematic diagram of an electronic device provided in an embodiment of this application.

[0171] The electronic device 100 includes one or more antenna slot structures provided in the above embodiments. The following is a specific description using an example of an antenna slot structure provided in multiple embodiments.

[0172] The electronic device 100 includes a first short side 101, a first long side 102, a second short side 103, and a second long side 104 connected in sequence.

[0173] Among them, such as Figure 19 As shown, when the electronic device 100 is in portrait mode, the first short side 101 is the top side of the electronic device 100, the first long side 102 is the right side of the electronic device 100, the second short side 103 is the bottom side of the electronic device 100, and the second long side 103 is the left side of the electronic device 100.

[0174] The plurality of antenna slot structures include a first group of antenna slot structures and a second group of antenna slot structures. The first group of antenna slot structures is located on the first long side 102, and the second group of antenna slot structures is located on the second long side 104.

[0175] That is to say Figure 19 The first group of antenna slot structures includes antenna slot structures 31 and 32. The second group of antenna slot structures includes antenna slot structure 33.

[0176] At this time, the first short side 101 and the second short side 103 of the electronic device may be provided with the antenna slot structure shown in FIG3, or may not be provided with the antenna slot structure. This application embodiment does not specifically limit this.

[0177] The antenna structure provided in this application embodiment is preferentially set on the long side of the electronic device because, compared with the short side, the long side of the electronic device is more susceptible to bending, squeezing or dropping during assembly or use, which may cause the metal frame and insulating plastic in the antenna slot structure to break or the insulating plastic to break. Therefore, the above electronic device is provided with the antenna slot structure provided in this application embodiment on the long side.

[0178] In other embodiments, to further ensure the reliability of the antenna slot structure, the plurality of antenna slot structures include a third group of antenna slot structures and a fourth group of antenna slot structures. The third group of antenna slot structures is located on the first short side 101, and the fourth group of antenna slot structures is located on the second short side 103.

[0179] That is to say Figure 19 The third group of antenna slot structures includes antenna slot structures 34 and 35. The second group of antenna slot structures includes antenna slot structure 36.

[0180] At this point, all antenna slot structures adopt the implementation method provided in the embodiments of this application, which further enhances the airtightness of the electronic device, thereby ensuring the dustproof and waterproof capabilities of the electronic device.

[0181] The embodiments of this application do not limit the specific number of antenna slots included in the first group of antenna slots, the second group of antenna slots, the third group of antenna slots, and the fourth group of antenna slots. The above description is only one possible implementation.

[0182] For details on the specific implementation and principle of the antenna slot structure, please refer to the relevant descriptions in the above embodiments. The embodiments of this application will not be repeated here.

[0183] The appearance of the electronic devices listed in the embodiments of this application is only one possible implementation and does not constitute a limitation on the technical solution of this application.

[0184] The electronic devices provided in this application can be mobile phones, laptops, wearable electronic devices (such as smartwatches), tablets, AR devices, VR devices, and in-vehicle devices, etc., and the embodiments of this application are not specifically limited.

[0185] In summary, the antenna slot structure of this electronic device incorporates a first groove and / or a second groove. Filling both the groove and the antenna slot with insulating plastic increases the contact area between the insulating plastic and the metal frame, thereby improving the stability and bonding strength of the connection between the insulating plastic and the metal frame. Specifically, filling the first groove with insulating plastic increases the thickness of the insulating plastic near the antenna slot, reducing the probability of breakage. The second groove structure provides restraint and locking for the insulating plastic, reducing the likelihood of cracking in the antenna slot structure under bending, compression, or drop conditions. This enhances the airtightness of the electronic device, thus ensuring its dustproof and waterproof capabilities.
