Description

Technical Field

[0001] The present disclosure relates to the technical field of terminal equipment, and in particular to a terminal equipment. Background Art

[0002] As terminal devices gradually develop in the direction of full screen, the display area of ​​the screen in the terminal devices is getting larger and larger. However, an overly large display area of ​​the screen will compress the antenna clearance, resulting in a decrease in the antenna's radiation performance. On the contrary, meeting the antenna clearance requirement will sacrifice the size of the screen display area. As a result, the terminal device cannot take into account both the higher radiation efficiency of the antenna and the larger display area of ​​the screen, making it difficult to meet usage requirements. Utility Model Content

[0003] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0004] To this end, an object of the present disclosure is to provide a terminal device.

[0005] To achieve the above-mentioned purpose, the present disclosure provides a terminal device, comprising: a metal frame, the metal frame comprising: at least one radiating arm arranged along the circumference of the metal frame; a screen, the screen is arranged at an inner end of the metal frame, and the screen comprises: a black matrix BM area arranged along the circumference of the metal frame, the BM area and the radiating arm at least partially overlap along the width direction of the metal frame; wherein, a first groove is provided at one end of the inner side of the radiating arm close to the screen along the thickness direction of the metal frame, and the first groove and the BM area do not overlap along the width direction of the metal frame.

[0006] Optionally, the terminal device further includes: a first filling body, at least a portion of which is disposed in the first groove, and the first filling body has a hardness above a first threshold and a strength above a second threshold.

[0007] Optionally, the first filling body includes: a first part, which is arranged in the first groove; and a second part, which is arranged on the inner side of the metal frame and is respectively connected to the first part, the screen and an end of the inner side of the metal frame away from the screen.

[0008] Optionally, the terminal device further includes: a reinforcement layer, wherein the reinforcement layer is arranged on the inner side of the bending section of the radiation arm, and the reinforcement layer is located at an end of the radiation arm away from the first groove.

[0009] Optionally, the thickness of the reinforcement layer is not less than 0.5 mm; and / or the thickness of the reinforcement layer is not more than 1 mm.

[0010] Optionally, the radiating arm includes: a feeding point, which is arranged in a non-bending section of the radiating arm; and / or a grounding point, which is arranged in the non-bending section of the radiating arm.

[0011] Optionally, the feeding point and / or the grounding point is arranged at an end of the non-bending section close to the bending section.

[0012] Optionally, the distance between the bottom of the first groove and the outer side of the radiation arm is not less than 4 mm.

[0013] Optionally, a second groove is provided on the inner side of the radiation arm near one end of the screen along the thickness direction of the metal frame, at least part of the BM area is provided in the second groove, and the first groove is provided at the bottom of the second groove along the thickness direction of the metal frame.

[0015] The technical solution provided by the present disclosure may have the following beneficial effects:

[0016] Since the first groove and the BM area do not overlap along the width direction of the metal frame, the radiation signal of the radiation arm can radiate outward using the first groove, thereby effectively increasing the clearance size of the radiation arm and improving the radiation efficiency of the radiation arm. At the same time, while ensuring that the radiation efficiency of the radiation arm remains unchanged, the size of the BM area can be greatly reduced, thereby increasing the size of the display area of ​​the screen, which is conducive to realizing the full-screen design of the screen. Therefore, through the setting of the first groove, the high radiation efficiency of the antenna and the large display area of ​​the screen in the terminal device are taken into account, meeting the use requirements.

[0031] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0032] like Figure 1 As shown, a related embodiment proposes a terminal device, including a metal frame A1 and a screen A2, the metal frame A1 includes at least one radiation arm A11 arranged along the circumference of the metal frame A1, the screen A2 is arranged at an inner end of the metal frame A1, and the screen A2 includes a BM (Black Matrix) area A21 arranged along the circumference of the metal frame A1, and the BM area A21 and the radiation arm A11 at least partially overlap along the width direction of the metal frame A1.

[0033] It can be understood that since the BM area A21 and the radiation arm A11 at least partially overlap along the width direction of the metal frame A1, not only can the metal frame A1 be used to support the screen A2 so that the screen A2 can be stably set, but the non-metallic properties of the BM area A21 can also be used to allow the radiation signal of the radiation arm A11 to pass, thereby meeting the clearance A12 requirement of the radiation arm A11.

[0034] Among them, since the BM area A21 does not display an image, the size of the display area A22 of the screen A2 is limited by the size of the BM area A21, that is, the smaller the size of the BM area A21, the larger the display area A22 of the screen A2, and the larger the size of the BM area A21, the smaller the display area A22 of the screen A2. At the same time, since the overlapping part of the BM area A21 and the radiation arm A11 along the width direction of the metal frame A1 forms the clearance A12 of the radiation arm A11, the size of the clearance A12 of the radiation arm A11 is limited by the size of the BM area A21, that is, the smaller the size of the BM area A21, the smaller the size of the BM area A21, and the larger the size of the BM area A21, the larger the size of the BM area A21.

[0035] From this, it can be seen that an overly large display area A22 of the screen A2 will compress the antenna's clearance A12, resulting in a decrease in the antenna's radiation performance. Conversely, meeting the antenna's clearance A12 requirement will sacrifice the size of the screen A2's display area A22. As a result, the terminal device cannot take into account both the higher radiation efficiency of the antenna and the larger display area A22 of the screen A2, making it difficult to meet usage requirements.

[0036] To solve the above technical problems, Figure 2 As shown, an embodiment of the present disclosure proposes a terminal device, including a metal frame 1 and a screen 2, wherein the metal frame 1 includes at least one radiation arm 11 arranged along the circumference of the metal frame 1, the screen 2 is arranged at an inner end of the metal frame 1, and the screen 2 includes a BM area 21 arranged along the circumference of the metal frame 1, the BM area 21 and the radiation arm 11 at least partially overlap along the width direction of the metal frame 1, wherein a first groove 12 is provided at one end of the inner side of the radiation arm 11 close to the screen 2 along the thickness direction of the metal frame 1, and the first groove 12 and the BM area 21 do not overlap along the width direction of the metal frame 1.

[0037] It can be understood that since the BM area 21 and the radiation arm 11 at least partially overlap along the width direction of the metal frame 1, not only can the metal frame 1 be used to support the screen 2 so that the screen 2 can be stably set, but the non-metallic properties of the BM area 21 can also be used to allow the radiation signal of the radiation arm 11 to pass, thereby meeting the clearance 14 requirement of the radiation arm 11.

[0038] Moreover, since the first groove 12 and the BM area 21 do not overlap along the width direction of the metal frame 1, the radiation signal of the radiation arm 11 can be radiated outward by using the first groove 12, thereby effectively increasing the clearance 14 size of the radiation arm 11 and improving the radiation efficiency of the radiation arm 11. At the same time, while ensuring that the radiation efficiency of the radiation arm 11 remains unchanged, the size of the BM area 21 can be greatly reduced, thereby increasing the size of the display area 22 of the screen 2, thereby facilitating the realization of a full-screen design of the screen 2. Therefore, by setting the first groove 12, a balance between a higher radiation efficiency of the antenna in the terminal device and a larger display area 22 of the screen 2 is achieved, meeting the use requirements.

[0039] It should be noted that the specific type of terminal device can be set according to actual needs and is not limited to this. For example, the terminal device can be a mobile phone, a tablet computer, a wearable smart device, a car terminal, etc.

[0040] The metal frame 1 is made of metal material, which is the structure of the edge of the metal middle frame. The metal frame 1 can use its metal properties to stimulate radiation current, thereby radiating signals to meet the communication needs of the terminal equipment. The specific type of the metal frame 1 can be set according to actual needs and is not limited to this. For example, the metal frame 1 can be rectangular, circular, etc.

[0041] The metal frame 1 may include a radiation arm 11 arranged along the circumference of the metal frame 1, or may include multiple radiation arms 11 arranged along the circumference of the metal frame 1, and there is no limitation on this. Moreover, the radiation arm 11 may include only a bending section 113, or only a non-bending section 114, or may include both a bending section 113 and a non-bending section 114. The bending section 113 may be a corner position of the metal frame 1, and the non-bending section 114 may be a straight plate position of the metal frame 1.

[0042] The BM area 21 is used to prevent light leakage from the edge of the screen 2. The BM area 21 does not display images and is located around the display area 22 of the screen 2. The BM area 21 can be made of non-metallic materials such as plastic. The specific type of the BM area 21 can be set according to actual needs and is not limited to this.

[0043] The first groove 12 is used to reduce the thickness of the radiation arm 11 to increase the size of the clearance 14 of the radiation arm 11. The specific type of the first groove 12 can be set according to actual needs and is not limited thereto.

[0044] like Figure 3 As shown, in some embodiments, the terminal device further includes a first filling body 3, at least a portion of the first filling body 3 is disposed in the first groove 12, and the first filling body 3 has a hardness above a first threshold and a strength above a second threshold.

[0045] It can be understood that since the first filling body 3 has a hardness above the first threshold and a strength above the second threshold, when the first filling body 3 is arranged in the first groove 12, it can form a strong support for the radiation arm 11 whose thickness is reduced due to the setting of the first groove 12, thereby ensuring that the hardness and strength of the metal frame 1 can meet the use requirements.

[0046] It should be noted that the specific type of the first filling body 3 can be set according to actual needs and is not limited to this. For example, the first filling body 3 can be injection-molded plastic.

[0047] The first threshold and the second threshold can be set according to actual needs, and there is no limitation on this. For example, the model of the injection molded plastic can be "P430B".

[0048] like Figure 3 As shown, in some embodiments, the first filling body 3 includes a first part 31 and a second part 32, the first part 31 is arranged in the first groove 12, the second part 32 is arranged on the inner side of the metal frame 1, and the second part 32 is respectively connected to the first part 31, the screen 2 and the end of the inner side of the metal frame 1 away from the screen 2.

[0049] It can be understood that, since the first part 31 is arranged in the first groove 12, the first filling body 3 can form a strong support for the end of the radiating arm 11 close to the screen 2. At the same time, since the second part 32 is connected to the end of the inner side of the metal frame 1 away from the screen 2, the first filling body 3 can also form a strong support for the end of the radiating arm 11 away from the screen 2. Therefore, it is ensured that the metal frame 1 has greater hardness and strength, thereby meeting the use requirements.

[0050] At the same time, since the second part 32 is connected to the screen 2 , the first filling body 3 can also provide strong support for the screen 2 , thereby ensuring the stable setting of the screen 2 .

[0051] It should be noted that the specific types of the first part 31 and the second part 32 can be set according to actual needs and are not limited to this. For example, after the screen 2 is set on the inner side of the metal frame 1, the first filling body 3 is injection molded into the inner side of the metal frame 1 to form the first part 31 and the second part 32.

[0052] like Figure 3 As shown, in some embodiments, the terminal device further includes a reinforcement layer 4 , which is disposed inside the bending section 113 of the radiation arm 11 , and the reinforcement layer 4 is located at an end of the radiation arm 11 away from the first groove 12 .

[0053] It can be understood that since the reinforcement layer 4 is arranged on the inner side of the bending section 113 of the radiation arm 11, and the reinforcement layer 4 is located at the end of the radiation arm 11 away from the first groove 12, the thickness of the radiation arm 11 away from the first groove 12 is increased, thereby effectively improving the hardness and strength of the radiation arm 11, thereby ensuring that the hardness and strength of the metal frame 1 can meet the use requirements.

[0054] It should be noted that the reinforcement layer 4 is used to increase the thickness of the end of the radiation arm 11 away from the first groove 12. The specific type of the reinforcement layer 4 can be set according to actual needs and is not limited to this. For example, the reinforcement layer 4 can be a structure independently installed on the inner side of the radiation arm 11, or it can be a structure formed by thickening the radiation arm 11.

[0055] In some embodiments, the thickness of the reinforcement layer 4 is not less than 0.5 mm; and / or the thickness of the reinforcement layer 4 is not greater than 1 mm.

[0056] It can be understood that by setting the thickness of the reinforcing layer 4 to be no less than 0.5 mm, the thickness of the end of the radiating arm 11 away from the first groove 12 is greatly improved, thereby ensuring that the metal frame 1 has a greater hardness and strength to meet the use requirements; by setting the thickness of the reinforcing layer 4 to be no more than 1 mm, the thickness of the end of the radiating arm 11 away from the first groove 12 is avoided from being too large, which is conducive to the realization of a full-screen design of the terminal device.

[0057] It should be noted that the thickness of the reinforcing layer 4 can be set according to actual needs, and there is no limitation on this. For example, the thickness of the reinforcing layer 4 can be 0.5 mm, 0.61 mm, 0.7 mm, 0.86 mm, 0.9 mm, 1 mm, etc.

[0058] like Figure 4 As shown, in some embodiments, the radiating arm 11 includes a feeding point 111 and a grounding point 112 , the feeding point 111 is disposed at a non-bending section 114 of the radiating arm 11 ; and / or the grounding point 112 is disposed at the non-bending section 114 of the radiating arm 11 .

[0059] It can be understood that due to the setting of the first groove 12, the thickness of the radiation arm 11 is reduced, and the hardness and strength of the metal frame 1 are reduced, especially at the bending section 113 of the radiation arm 11, and because the setting of the feeding point 111 and the grounding point 112 requires metal removal, the hardness and strength of the feeding point 111 and the grounding point 112 in the metal frame 1 will be further reduced.

[0060] Therefore, by setting the feeding point 111 in the non-bending section 114 of the radiating arm 11, and setting the grounding point 112 in the non-bending section 114 of the radiating arm 11, the influence of the feeding point 111 and the grounding point 112 on the bending section 113 of the radiating arm 11 can be reduced, thereby ensuring that the metal frame 1 has greater hardness and strength, thereby meeting the use requirements.

[0061] It should be noted that the feeding point 111 is used to feed the excitation signal to the radiating arm 11. The specific type of the feeding point 111 can be set according to actual needs and is not limited to this. For example, the feeding point 111 can be connected to the feeding end of the circuit board using a spring clip, and multiple feeding points 111 can be respectively distributed at the top, bottom, side and other positions of the metal frame 1.

[0062] The grounding point 112 is used to return the excitation current in the radiation arm 11. The specific type of the grounding point 112 can be set according to actual needs and is not limited to this. For example, the grounding point 112 can be connected to the grounding end of the circuit board using a spring clip, and multiple grounding points 112 can be distributed at the top, bottom, side and other positions of the metal frame 1.

[0063] like Figure 4 As shown, in some embodiments, the feeding point 111 and / or the grounding point 112 is disposed at one end of the non-bending section 114 close to the bending section 113 .

[0064] It is understandable that before the first groove 12 is set, part of the feeding point 111 and / or the grounding point 112 will be in the bending section 113 of the radiating arm 11, which causes the overall hardness and strength of the radiating arm 11 to be greatly reduced after the first groove 12 is set. Therefore, by setting the feeding point 111 and / or the grounding point 112 at one end of the non-bending section 114 close to the bending section 113, it is possible to ensure stable feeding and grounding of the radiating arm 11, and also ensure that the radiating arm 11 has high hardness and strength, thereby meeting the use requirements.

[0065] In some embodiments, the distance between the bottom of the first groove 12 and the outer side of the radiation arm 11 is not less than 4 mm.

[0066] It can be understood that by setting the distance between the bottom of the first groove 12 and the outer side of the radiating arm 11 to be no less than 4 mm, the distance between the bottom of the first groove 12 and the outer side of the radiating arm 11 is avoided from being too small, thereby ensuring that the end of the radiating arm 11 close to the screen 2 still has a certain thickness after the first groove 12 is set, thereby ensuring that the metal frame 1 has high hardness and strength.

[0067] It should be noted that the distance between the bottom of the first groove 12 and the outer side of the radiation arm 11 can be set according to actual needs, and there is no limitation on this. For example, the distance between the bottom of the first groove 12 and the outer side of the radiation arm 11 can be 4mm, 4.1mm, 4.5mm, 4.9mm, 5mm, etc.

[0068] like Figure 2 As shown, in some embodiments, a second groove 13 is provided at one end of the inner side of the radiation arm 11 close to the screen 2 along the thickness direction of the metal frame 1, at least a portion of the BM region 21 is provided in the second groove 13, and the first groove 12 is provided at the bottom of the second groove 13 along the thickness direction of the metal frame 1.

[0069] It can be understood that, since at least part of the BM area 21 is arranged in the second groove 13, the radiation arm 11 can use the second groove 13 to effectively support the BM area 21, thereby ensuring the stable setting of the screen 2 on the metal frame 1, and facilitating the arrangement of the second groove 13 on the inner side of the radiation arm 11.

[0070] It should be noted that the specific type of the second groove 13 can be set according to actual needs and is not limited thereto, wherein the first filling body 3 fills the second groove 13 while filling the first groove 12 .

[0071] like Figure 3 As shown, in some embodiments, the terminal device further includes a second filling body 5 , which is disposed at one end of the first groove 12 close to the screen 2 , and the second filling body 5 is located between the screen 2 and the metal frame 1 .

[0072] It can be understood that since the second filling body 5 is arranged at one end of the first groove 12 close to the screen 2, and the second filling body 5 is located between the screen 2 and the metal frame 1, the second filling body 5 can fill the gap between the screen 2 and the metal frame 1 due to the setting of the second groove 13, thereby ensuring the stable setting between the screen 2 and the metal frame 1 and reducing the interference of the external environment on the metal frame 1.

[0073] It should be noted that the specific type of the second filling body 5 can be set according to actual needs and is not limited to this. For example, the second filling body 5 can be a non-metallic filler such as caulking glue.

[0074] In the description of the present disclosure, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present disclosure, unless otherwise specified, "plurality" means two or more.
