Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to an electronic device. Background Art

[0002] As technology continues to advance, users are increasingly demanding the screen size of terminal devices. Therefore, terminal devices with large screen displays are increasingly favored by users. For example, foldable screen mobile phones can be divided into internal foldable screen mobile phones and external foldable screen mobile phones. Among them, due to its own structure, the internal space for setting the antenna of the external foldable screen mobile phone is relatively small, which restricts the setting of the antenna and affects the antenna performance and signal strength. Summary of the invention

[0003] An embodiment of the present application provides an electronic device for solving the problem that the internal space of the electronic device is limited, resulting in the location of the antenna being restricted, thereby affecting the antenna performance and signal strength.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] An embodiment of the present application provides an electronic device, which includes a housing, a mainboard, components, and a bracket. The mainboard is arranged in the housing. The components are arranged on the mainboard and are electrically connected to the mainboard. The bracket is arranged on a side of the component away from the mainboard, the bracket includes a plastic part and a metal part, the metal part is embedded in the plastic part, the metal part includes a plurality of sub-brackets, the plurality of sub-brackets are spaced apart, and at least one of the plurality of sub-brackets is used as a radiator of the antenna.

[0006] The electronic device provided in the embodiment of the present application divides the metal part of the bracket into multiple independent sub-brackets, and uses at least one of the sub-brackets as the radiator of the antenna, which is beneficial to reducing the space occupied by the antenna inside the shell and reducing the impact of constraints on the antenna setting due to the small space, thereby ensuring the antenna performance and signal strength.

[0007] Furthermore, since the metal portion of the bracket is configured as a plurality of mutually independent sub-brackets, the physical size of the antenna as a radiator can be adjusted so that the sub-bracket can match the frequency band of the antenna, thereby facilitating enhancement of the antenna radiation signal.

[0008] In a possible implementation of the present application, multiple sub-brackets are spaced apart along a first direction, and the first direction is the length direction of the electronic device. Under this structure, the multiple sub-brackets are extended along the length direction of the electronic device without increasing the width dimension of the electronic device. For example, for an external folding screen mobile phone, the setting space for the motherboard and the bracket is small, so multiple sub-brackets are distributed along the length direction, which is conducive to saving internal space.

[0009] In a possible implementation of the present application, along the first direction, partial areas of two adjacent sub-brackets overlap each other along the second direction, and the second direction is perpendicular to the first direction and parallel to the mainboard. In this way, the two adjacent sub-brackets can form a continuous support structure along the first direction, that is, there is no breakpoint between the two along the first direction, thereby improving the overall support strength of the bracket.

[0010] In a possible implementation of the present application, along the first direction, at least one sub-bracket between two sub-brackets at both ends is used as a radiator of the antenna. That is, the sub-bracket used as the antenna radiator is located in the middle area along the length direction to avoid shielding the antenna signal when the user holds the electronic device, which is conducive to further improving the signal strength of the antenna.

[0011] In a possible implementation of the present application, the plurality of sub-brackets include a first sub-bracket and two second sub-brackets, the first sub-bracket is located between the two second sub-brackets; the first sub-bracket is provided with a grounding point, the second sub-bracket is provided with at least one grounding point, and the first sub-bracket is electrically connected to the antenna. In this way, the metal part of the bracket includes three sub-brackets, and the first sub-bracket is provided between the two second sub-brackets, thereby further ensuring that when the user holds the electronic device, the first sub-bracket is not blocked, so as to ensure the signal strength of the antenna.

[0012] In a possible implementation of the present application, the housing includes a first shell and a second shell, the first shell and the second shell are rotatably connected, and the first shell and the second shell can rotate between a folded state and an unfolded state; the second shell includes a first part and a second part, and the thickness of the second part is greater than the thickness of the first part; when the first shell and the second shell are in a folded state, the first shell overlaps with the first part of the second shell, and the main board, components and brackets are all arranged in the second part of the second shell. That is, the electronic device is an external folding screen terminal, for example, a mobile phone with an external folding display screen, and the main board and components inside the electronic device are all arranged in the second part, and the available space is reduced. Therefore, the metal part of the bracket is divided into a plurality of sub-brackets, and at least one of the sub-brackets is used as a radiator of the antenna, which is conducive to saving space and ensuring the antenna signal strength.

[0013] In a possible implementation of the present application, the multiple sub-brackets include a first sub-bracket, and the first sub-bracket is used as a radiator of the antenna. When the first shell and the second shell are in a folded state, the wall plate of the first part of the first shell facing the second shell is the first wall plate, and the first wall plate and the first sub-bracket serve as the antenna radiator together. That is, when the electronic device is in a folded state, the current on the first sub-bracket can be coupled to the first wall plate, and the antenna signal is radiated through the first wall plate, that is, the antenna signal is further amplified and enhanced, which is conducive to further improving the signal strength.

[0014] In a possible implementation of the present application, the first sub-bracket includes a first area and a second area, an angle is formed between the first area and the second area, and when the first shell and the second shell are in a folded state, the first area and the first wall plate serve together as the radiator of the antenna. That is, when the first area and the first wall plate are arranged relative to each other, coupling can occur between the two, and the antenna signal can be further amplified and enhanced through the first wall plate, which is conducive to improving the signal strength.

[0015] In a possible implementation of the present application, a grounding point is provided on the second area. For example, the grounding point of the second area can be grounded by a screw. In this way, on the one hand, grounding can be achieved, and on the other hand, the first sub-bracket can be fixedly connected to the mainboard or other structural parts, which is conducive to improving the connection reliability of the bracket.

[0016] In a possible implementation of the present application, a connection point is provided at the first area, and the connection point is electrically connected to the mainboard. For example, a metal spring can be welded between the mainboard and the connection point, so as to realize electrical connection between the mainboard and the first sub-bracket.

[0017] In a possible implementation of the present application, when the first shell and the second shell are in a folded state, the distance between the first wall plate and the first area of ​​the first sub-bracket ranges from 0.5 mm to 2 mm. That is, the smaller the distance between the first wall plate and the first area, the more conducive it is to enhancing the antenna signal.

[0018] In a possible implementation of the present application, the antenna includes a WIFI antenna. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0036] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0037] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0038] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0039] An embodiment of the present application provides an electronic device. Specifically, the electronic device may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, and the mobile phone may be a mobile phone with an external folding display screen, or a mobile phone with an external folding display screen. For the convenience of explanation, the following examples are all taken as an example that the electronic device is a mobile phone with an external folding display screen.

[0040] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a structural diagram of an electronic device 01 provided in an embodiment of the present application in an unfolded state. Figure 2 This is an exploded view of the electronic device 01 provided in the embodiment of the present application in a folded state. Figure 3 The electronic device 01 provided in the embodiment of the present application is in a folded state. The electronic device 01 may include a folding screen 10, a supporting device 20, a mainboard 30, components 40 and a bracket 50; and the electronic device 01 can be rotated between an unfolded state and a folded state.

[0041] The above-mentioned folding screen 10 is used to display images, videos, etc. The folding screen 10 may include a first display area 11, a second display area 12 and a third display area 13, and the third display area 13 is located between the first display area 11 and the second display area 12. When the folding screen 10 is bent, the third display area 13 is bent, and the first display area 11 and the second display area 12 are arranged in opposite directions. At least the third display area 13 of the folding screen 10 is made of a flexible material. The first display area 11 and the second display area 12 can be made of a flexible material, or a rigid material, or partially made of a flexible material and partially made of a rigid material. Therefore, the embodiment of the present application does not specifically limit this.

[0042] Among them, the above-mentioned folding screen 10 can be an organic light emitting diode (OLED) display screen, an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED) display screen, a mini light emitting diode (MINI) display screen, a micro light emitting diode (MICRO) display screen, a micro organic light emitting diode (MICRO) display screen, a quantum dot light emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0043] The supporting device 20 is used to support the folding screen 10. The supporting device 20 may include a first shell 21, a second shell 22 and a rotating mechanism 23, wherein the rotating mechanism 23 is connected between the first shell 21 and the second shell 22, that is, the first shell 21, the second shell 22 and the rotating mechanism 23 form the housing of the electronic device 01. The first display area 11 of the folding screen 10 is connected to the first shell 21, the second display area 12 of the folding screen 10 is connected to the second shell 22, and the third display area 13 of the folding screen 10 is connected to the rotating mechanism 23. The first shell 21 and the second shell 22 are rotatably connected through the rotating mechanism 23, so that the electronic device 01 can rotate between the unfolded state and the folded state.

[0044] Specifically, see Figure 4 and Figure 5 , Figure 4 This is a front view of an electronic device 01 in an unfolded state provided in an embodiment of the present application. Figure 5 A front view of an electronic device 01 in a folded state provided in an embodiment of the present application. The first housing 21 has a first support surface 21a, the second housing 22 has a second support surface 22a, and the rotating mechanism 23 has a third support surface 23a. The first display area 11 of the folding screen 10 is supported and attached to the first support surface 21a of the first housing 21, the second display area 12 of the folding screen 10 is supported and attached to the second support surface 22a of the second housing 22, and the third display area 13 of the folding screen 10 is supported and attached to the third support surface 23a of the rotating mechanism 23.

[0045] When the electronic device 01 is in the unfolded state, the first support surface 21a, the second support surface 22a and the third support surface 23a are in the same plane, so that the folding screen 10 is fully unfolded, that is, the first display area 11, the second display area 12 and the third display area 13 of the folding screen 10 are in the same plane, and the flatness can be guaranteed. In this state, a large-screen display can be achieved, which can bring a better user experience. For example, when a user uses the electronic device 01 to watch a movie, the electronic device 01 can be unfolded and watched on a large screen, thereby obtaining a better viewing experience.

[0046] When the electronic device 01 is in the folded state, the first display area 11 and the second display area 12 of the folding screen 10 are separated from each other, that is, the first display area 11 and the second display area 12 are facing opposite directions, the third display area 13 of the folding screen 10 is in a bent state, and the supporting device 20 is located between the first display area 11 and the second display area 12 of the folding screen 10. At this time, the electronic device 01 only uses the first display area 11 or the second display area 12 of the folding screen 10 to display images ( Figure 5The electronic device 01 shown is in a folded state, and uses the second display area 12 of the folding screen 10 to display images), that is, the user can use the small screen for one-handed operation. For example, when a user takes public transportation, one hand needs to hold the handrail, so the device can only be held with one hand. At this time, the electronic device 01 can be folded to reduce the width of the device, thereby facilitating one-handed operation, which is conducive to improving the user experience.

[0047] When the electronic device 01 is in the folded screen 10 state, the support device 20 is located between the first display area 11 and the second display area 12 of the folded screen 10. In this case, the folded screen 10 can be seen from the appearance of the electronic device 01. To enable the electronic device 01 to use the rear camera module for shooting when in the folded state, please continue to refer to Figure 4 , Figure 5 Combined with Figure 3 The second shell 22 may include a first portion 22b and a second portion 22c. When the electronic device 01 is in the unfolded state, the first shell 21, the rotating mechanism 23, the first portion 22b of the second shell 22 and the second portion 22c of the second shell 22 are arranged in sequence.

[0048] Specifically, the sum of the thicknesses of the first shell 21 and the folding screen 10 is the first thickness D1, the sum of the thicknesses of the first part 22b of the second shell 22 and the folding screen 10 is the second thickness D2, the sum of the thicknesses of the second part 22c of the second shell 22 and the folding screen 10 is the third thickness D3, the first thickness D1 is equal to the second thickness D2, and both are less than the third thickness D3.

[0049] When the electronic device 01 is in the folded state, the first housing 21 overlaps with the first portion 22 b of the second housing 22 , and the sum of the first thickness D1 and the second thickness D2 is equal to the third thickness D3 .

[0050] In this way, when the electronic device 01 is in the folded state, the first housing 21 will not block the second portion 22c of the second housing 22, that is, will not block the wall of the second portion 22c away from the second support surface 22a. Therefore, the rear camera module can be arranged inside the second portion 22c of the second housing 22, and the light emitting surface of the rear camera module can be arranged on the wall of the second portion 22c away from the second support surface 22a, so that the electronic device 01 can use the rear camera module for shooting regardless of whether it is in the folded state or the unfolded state.

[0051] Please return to Figure 2The mainboard 30 is used to set the components 40 and realize the electrical connection between the components 40. The mainboard 30 can be fixed inside the first shell 21 or the second shell 22 by gluing, threading, welding, clamping, etc. Therefore, the present application does not specifically limit the fixing method of the mainboard 30.

[0052] The components 40 are used to implement various functions of the electronic device 01. For example, the components 40 include the rear camera module, the front camera module, a control chip (such as a system on chip, SOC), a graphics control chip (graphics processing unit, GPU), a universal storage (UFS), a flash module, etc.

[0053] The bracket 50 is used to press the components 40, that is, the components 40 are arranged between the mainboard 30 and the bracket 50, and the bracket 50 can press the components 40 arranged on the mainboard 30, so as to fix, press and support the components 40. Figure 6 , Figure 6 The structural diagram of the bracket 50 provided in the related technology, the bracket 50 may include a plastic part 51 and a metal part 52. The plastic part 51 has a lower hardness and can reduce the risk of damage to the component 40. The metal part 52 is embedded in the plastic part 51 to enhance the overall strength of the bracket 50.

[0054] In order to facilitate the description of the following embodiments, an XYZ coordinate system is established, and the width direction of the electronic device 01 is defined as the X-axis direction, the length direction of the electronic device 01 is defined as the Y-axis direction, and the thickness direction of the electronic device 01 is defined as the Z-axis direction. The width direction refers to the direction in which the first shell 21, the rotating mechanism 23, the first part 22b of the second shell 22, and the second part 22c of the second shell 22 are sequentially distributed when the electronic device 01 is in the unfolded state; the thickness direction refers to the direction in which the first shell 21 and the first part 22b of the second shell 22 are stacked on each other when the electronic device 01 is in the folded state. The above-mentioned first thickness D1, second thickness D2, and third thickness D3 are all thickness dimensions along the Z-axis direction. It can be understood that the XYZ coordinate system can be flexibly set according to actual needs. The embodiment of the present application only provides an example and cannot be considered as a special limitation to the present application.

[0055] In some embodiments, please refer to Figure 6 Combined with Figure 2Since the thickness of the second portion 22c of the second housing 22 along the Z-axis direction (i.e., the third thickness D3) is relatively large, the main board 30, the components 40, and the bracket 50 can be disposed inside the second portion 22c. The main board 30 and the bracket 50 can both extend along the Y-axis direction, so that a plurality of components 40 can be disposed on the main board 30.

[0056] In addition, in order to enable the electronic device 01 to communicate with other devices, different antennas need to be set inside the electronic device 01. For example, a WIFI antenna, a Bluetooth antenna, a communication antenna, and a GPS antenna, etc. The antenna can be set on the second shell 22, that is, on the frame of the second part 22c of the second shell 22, forming a frame antenna; it can also be set inside the second shell 22.

[0057] However, please continue to see Figure 6 Combined with Figure 2 Since the second portion 22c of the second housing 22 has a smaller size along the X-axis direction, there are fewer locations on the second portion 22c where the frame antenna can be set, which results in restrictions on the setting of some antennas, affecting the radiation signal strength of the antennas.

[0058] Based on this, the embodiment of the present application provides a bracket for the above-mentioned electronic device 01, please refer to Figure 7 , Figure 7 The exploded structure diagram of a bracket 50 provided in an embodiment of the present application includes a plastic portion 51 and a metal portion 52. The metal portion 52 of the bracket 50 may include a plurality of sub-brackets 520, the plurality of sub-brackets 520 are distributed at intervals, and at least one of the plurality of sub-brackets 520 may be used as a radiator of an antenna. For example, the antenna may be a WIFI antenna with a frequency of 2.4 GHz.

[0059] In this way, the metal part 52 of the bracket 50 is divided into a plurality of sub-brackets 520, and some of the sub-brackets 520 are used as the radiator of the antenna, so as to reduce the number of frame antennas set on the second shell 22, that is, some antennas are in the form of cavity antennas, and the sub-brackets 520 are used as the antenna radiator, which is conducive to ensuring the signal strength of each antenna. In addition, the metal part 52 of the bracket 50 is divided into a plurality of independent sub-brackets 520, and the physical size of one of the sub-brackets 520 can be adjusted to match the physical size of the sub-bracket 520 with the frequency domain of the antenna, so that the sub-bracket 520 can be used as a radiator to amplify and enhance the antenna signal.

[0060] In addition, the metal portion 52 of the bracket 50 is divided into a plurality of sub-brackets 520 , which can reduce the overall weight of the bracket 50 , that is, the weight of the bracket 50 can be reduced without affecting the overall strength of the bracket 50 , thereby facilitating the thinning of the electronic device 01 .

[0061] In some embodiments, please refer to Figure 7 The above-mentioned multiple sub-brackets 520 are all embedded in the plastic part 51 of the bracket 50, and the multiple sub-brackets 520 can be distributed in sequence along the Y-axis direction. Therefore, the size of the bracket 50 along the X-axis direction does not increase, that is, the width size of the second part 22c does not need to be increased, which is conducive to improving the integration of the mainboard 30, the components 40 and the bracket 50.

[0062] In other embodiments, see Figure 8 , Figure 8 This is a structural diagram of a bracket 50 provided in an embodiment of the present application. Fig. 9 The structure diagram of the metal part 52 of the bracket 50 provided in the embodiment of the present application. Partial areas of two adjacent sub-brackets 520 in the above-mentioned multiple sub-brackets 520 overlap each other along the X-axis direction (such as Fig. 9 That is, among the multiple sub-brackets 520 embedded in the plastic part 51, two adjacent sub-brackets 520 can form a continuous support structure along the Y-axis direction, thereby reducing the weight while ensuring the overall support strength of the bracket 50.

[0063] It should be noted that any two adjacent sub-brackets 520 in the above-mentioned plurality of sub-brackets 520 may have some areas overlapping each other along the X-axis direction. Alternatively, some of the plurality of sub-brackets 520 may have some areas overlapping each other along the X-axis direction, and some of the plurality of sub-brackets 520 may not have some areas overlapping each other along the X-axis direction.

[0064] On this basis, in order to further ensure the signal strength of the antenna, along the Y-axis direction, at least one sub-bracket 520 between two sub-brackets 520 at both ends of the plurality of sub-brackets 520 can be used as a radiator of the antenna. Fig. 9 The plurality of sub-brackets 520 may include a first sub-bracket 521 and two second sub-brackets 522 . Along the Y-axis direction, the first sub-bracket 521 is disposed between the two second sub-brackets 522 , and the first sub-bracket 521 is used as a radiator of the antenna.

[0065] In this way, the first sub-bracket 521, which serves as the radiator of the antenna, is arranged between the two second sub-brackets 522, that is, the first sub-bracket 521 is located in the middle of the electronic device 01 along the Y-axis direction. Under this structure, when the user holds the electronic device 01, the palm of the user can be prevented from shielding the antenna signal. For example, when the electronic device 01 is in a folded state and the user is playing a game, the user's hands generally need to hold both ends of the electronic device 01 along the Y-axis direction. At this time, since the first sub-bracket 521 is located in the middle of the electronic device 01 along the Y-axis direction, the area covered by the user's palm does not overlap with the area where the first sub-bracket 521 is located, that is, the user's palm will not shield the signal emitted by the first sub-bracket 521 as the radiator of the antenna, which is beneficial to improve the signal strength of the antenna.

[0066] In addition, at least one grounding point 53 may be provided on the two second sub-brackets 522 so that each component 40 can be grounded nearby. In addition, a grounding point 53 may also be provided on the first sub-bracket 521. It is understood that the number and position of the grounding points 53 may be changed according to the distribution of the components 40.

[0067] Furthermore, the grounding point 53 of the sub-bracket 520 (including the first sub-bracket 521 and the second sub-bracket 522) can be grounded by a metal spring, or connected to the grounding point 53 in the second housing 22 by a screw. Therefore, the present embodiment does not specifically limit this.

[0068] In one possible example, see Fig.10 , Fig.10 A partial cross-sectional structural diagram of an electronic device 01 provided in an embodiment of the present application. The first housing 21 has a first wall panel 21b, and the second portion 22c of the second housing 22 has a second wall panel 22d and a third wall panel 22e. When the electronic device 01 is in a folded state, the first wall panel 21b is opposite to the second wall panel 22d, and the third wall panel 22e is located on a side of the second wall panel 22d away from the first wall panel 21b.

[0069] At least part of the first sub-bracket 521 may extend along the Z-axis direction. When the electronic device 01 is in a folded state, the first sub-bracket 521 and the first wall plate 21b may serve as a radiator of the antenna. Exemplarily, the first sub-bracket 521 may include a first area 521a and a second area 521b. The first area 521a extends along the Z-axis direction. The second area 521b is arranged parallel to the main board 30. The grounding point 53 on the first sub-bracket 521 may be arranged on the second area 521b and connected to the main board 30 by screws.

[0070] In this way, please refer to Fig.11 , Fig.11for Fig.10 The first sub-bracket 521 shown is a schematic diagram of signal radiation as an antenna radiator. Since the first area 521a on the first sub-bracket 521 extends along the Z-axis direction, when the electronic device 01 is in a folded state, the first area 521a and the first wall panel 21b are arranged opposite to each other, and coupling can occur between the two, that is, the current on the first sub-bracket 521 is coupled to the first wall panel 21b, thereby radiating electromagnetic waves to the surroundings through the first wall panel 21b, so as to further enhance the radiation intensity of the antenna signal.

[0071] Furthermore, the distance L between the first region 521a of the first sub-bracket 521 and the first wall plate 21b (eg Fig.10 The closer the first area 521a of the first sub-bracket 521 is, the stronger the signal strength radiated outward through the first wall plate 21b is. The distance L between the first area 521a of the first sub-bracket 521 and the first wall plate 21b can range from 0.5mm to 2mm. For example, the distance between the first area 521a of the first sub-bracket 521 and the first wall plate 21b can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 1.8mm or 2mm, etc.

[0072] Based on this, Fig.10 The electronic equipment 01 provided is used for signal simulation test, please refer to Fig.12 and Fig.13 , Fig.12 for Fig.10 The signal simulation diagram of the electronic device 01 for the return loss test is provided. Fig.13 for Fig.10 A signal simulation schematic diagram of the electronic device 01 provided for system efficiency testing.

[0073] Depend on Fig.12 It can be seen that curve A1 represents the simulation result of the return loss test of the electronic device 01 in free space, and point 1 represents the test value of the antenna frequency of 2.4 GHz, and point 2 represents the test value of the antenna frequency of 2.5 GHz; curve A2 represents the simulation result of the return loss test when the electronic device 01 is held in the right hand; curve A3 represents the simulation result of the return loss test when the electronic device 01 is held in the left hand.

[0074] Depend on Fig.13 It can be seen that curve B1 represents the simulation result of the system efficiency test of the electronic device 01 in free space, and point 1 represents the test value of the antenna frequency of 2.4 GHz; point 2 represents the test value of the antenna frequency of 2.5 GHz; curve B2 represents the simulation result of the system efficiency test when the electronic device 01 is held in the right hand; curve B3 represents the simulation result of the system efficiency test when the electronic device 01 is held in the left hand.

[0075] Depend on Fig.12 and Fig.13 It can be seen from the test results shown that the electronic device 01 provided in the embodiment of the present application has test results (including return loss test and system efficiency test) close to the test results of the electronic device 01 in free space when the user holds the electronic device 01 (including left hand and right hand), that is, the antenna signal will not be affected when the user holds the electronic device 01. Therefore, the electronic device 01 provided in the embodiment of the present application is conducive to improving the antenna signal strength.

[0076] Furthermore, after testing, the electronic device 01 provided by the embodiment of the present application is compared with the application Figure 6 For the electronic device 01 with the bracket 50 shown, when the user holds the electronic device 01 , the antenna signal can be increased by 50%.

[0077] In some other possible embodiments, since the first wall plate 21b of the first shell 21 is not necessarily parallel to the Z-axis direction, for example, the first wall plate 21b may form a certain angle with the ZY plane. Therefore, while the first area 521a of the first sub-bracket 521 extends along the Z-axis direction, it may also be inclined toward the second wall plate 22d or toward the third wall plate 22e (e.g., Fig.10 As shown), the first region 521a of the first sub-bracket 521 can tend to be parallel to the first wall plate 21b.

[0078] It can be understood that the first area 521a of the first sub-bracket 521 and the first wall plate 21b tend to be parallel to each other, which means that the two can be parallel to each other, for example, both are arranged along the YZ plane; or, the first area 521a and the first wall plate 21b can form a certain angle, for example, the first area 521a and the first wall plate 21b bracket 50 can form an angle less than 10°. Therefore, the embodiment of the present application does not make any special limitation on this.

[0079] Furthermore, to ensure that the first area 521a and the first wall plate 21b can be coupled, when the electronic device 01 is in the folded state, there cannot be conductive metal material between the first area 521a of the first sub-bracket 521 and the first wall plate 21b, that is, at least the portion of the second wall plate 22d located between the first wall plate 21b and the first area 521a cannot be made of metal material. For example, the portion of the second wall plate 22d located between the first wall plate 21b and the first area 521a can be made of plastic material; or, the second wall plate 22d can also be made entirely of plastic material.

[0080] Also, see Fig.14 , Fig.14A structural diagram of a first sub-bracket 521 provided in an embodiment of the present application. The first sub-bracket 521 can be electrically connected to the main board 30 through a metal spring. That is, a connection point 521d can be provided on one side of the edge of the first area 521a of the first sub-bracket 521 away from the second area 521b, and the connection point 521d is electrically connected to the main board through the metal spring, so that the first sub-bracket 521 can be used as a radiation point of the antenna.

[0081] In some embodiments, the first sub-bracket 521 may further include a third region 521c, which is disposed on a side of the first region 521a away from the second region 521b, and the third region 521c is located on a side of the above-mentioned component 40 away from the mainboard 30. That is, the third region 521c may be used to compress and fix the component 40. It is understandable that, since the first sub-bracket 521 is used as a radiator of the antenna, that is, the size of the first sub-bracket 521 needs to be adjusted according to the wavelength band of the antenna, the third region 521c may only cover a smaller portion of the mainboard 30 along the X-axis direction.

[0082] On this basis, see Fig.15 , Fig.15 A structural diagram of the metal part 52 of the bracket 50 provided in an embodiment of the present application. Among them, the second sub-bracket 522 of the above-mentioned bracket 50 may also include a fourth area 522a, a fifth area 522b and a sixth area 522c, and the fourth area 522a, the fifth area 522b and the sixth area 522c are distributed in sequence along the X-axis direction. The fourth area 522a is arranged on the side of the component 40 away from the mainboard 30, that is, it is used to press and fix the above-mentioned component 40, and the fourth area 522a can cover at least part of the mainboard 30, or it can cover the entire area of ​​the mainboard 30; and at least one grounding point 53 can be arranged on the fourth area 522a. The fifth area 522b extends along the Z-axis direction, and the sixth area 522c is arranged on the side of the fifth area 522b away from the fourth area 522a, and the sixth area 522c can be provided with at least one grounding point 53 connection.

[0083] To summarize, the bracket 50 provided in the embodiment of the present application divides the metal part 52 of the bracket 50 into multiple sub-brackets 520, so that at least one sub-bracket 520 (the above-mentioned first sub-bracket 521) among the multiple sub-brackets 520 serves as a radiator of the antenna, and adjusts the physical dimensions of the sub-bracket 520 so that the physical dimensions of the sub-bracket 520 serving as the radiator are within the frequency domain of the antenna, thereby enabling the antenna signal to be amplified and enhanced through the sub-bracket 520 to improve the strength of the antenna signal.

[0084] Furthermore, using at least one of the plurality of sub-brackets 520 as an individual antenna radiator is beneficial for saving the internal space of the second housing 22 and is beneficial for the arrangement of other antennas, thereby ensuring the antenna performance and signal strength.

[0086] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
