Terminal device and terminal system

Abstract

The utility model discloses terminal equipment and a terminal system, and belongs to the technical field of terminals. The terminal equipment comprises a frame body, a display screen, a flexible circuit board and a magnet assembly. The magnet assembly is arranged in the terminal equipment, and the magnetism of the side, facing the flexible circuit board, of the first magnet in the magnet assembly is opposite to the magnetism of the side, facing the flexible circuit board, of the second magnet in the magnet assembly. Therefore, it can be ensured that the direction of the acting force applied to the flexible circuit board by the first magnet in the magnet assembly is opposite to that of the acting force applied to the flexible circuit board by the second magnet in the magnet assembly. Thus, at least part of the acting force applied to the flexible circuit board by the first magnet in the magnet assembly is counteracted by the acting force applied to the flexible circuit board by the second magnet in the magnet assembly, so that the probability that the flexible circuit board generates vibration is small. Therefore, the probability that the flexible circuit board generates noise due to vibration is effectively reduced, and the reliability of the terminal equipment is further improved.

Description

[0001] The present application relates to the field of terminal technology, and in particular to a terminal device and a terminal system. Background Art

[0002] At present, tablet computers are loved by many users because they have the functions of both computers and mobile phones. With the emergence of keyboards for tablet computers, tablet computers can also be used to deal with some office documents urgently. The combination of tablet computers and keyboards has the advantages of being portable and enabling efficient office work.

[0003] Generally, a tablet computer is provided with a magnet for magnetically connecting with a keyboard, and the magnet is usually distributed near a flexible circuit board that is bound and connected with a display screen of the tablet computer.

[0004] However, when the tablet computer displays images, the alternating current transmitted inside the flexible circuit board will generate alternating electromagnetic force. Since there are magnets distributed near the flexible circuit board, the flexible circuit board may move toward the magnet and away from the magnet under the action of the alternating electromagnetic force generated inside the flexible circuit board, that is, the flexible circuit board will vibrate. Therefore, the flexible circuit board is very likely to generate noise due to vibration, which leads to low reliability of this tablet computer. Utility Model Content

[0009] The flexible circuit board is located in the accommodating space, and one end of the flexible circuit board is connected to the driving component;

[0014] Alternatively, when the number of the second magnets is two or more and the number of the first magnets is three or more, one first magnet is distributed between two adjacent second magnets, and the distance between any two adjacent first magnets and second magnets is equal.

[0015] Optionally, the first direction is parallel to a width direction of the flexible circuit board.

[0016] Optionally, the total area of ​​the end surfaces of the first magnets in the magnet assembly facing one end of the flexible circuit board is equal to the total area of ​​the end surfaces of the second magnets in the magnet assembly facing one end of the flexible circuit board.

[0021] The beneficial effects brought by the technical solution provided by the embodiment of the present application include at least:

[0022] A terminal device includes: a frame, a display screen, a flexible circuit board and a magnet assembly. Since a magnet assembly is provided in the terminal device, and the magnetism of the first magnet in the magnet assembly toward the side of the flexible circuit board can be opposite to the magnetism of the second magnet in the magnet assembly toward the flexible circuit board. Therefore, in the process of displaying images on the display screen in the terminal device, even if the flexible circuit board still transmits alternating current and generates alternating electromagnetic force, it can be ensured that the force applied by the first magnet in the magnet assembly to the flexible circuit board is opposite to the force applied by the second magnet in the magnet assembly to the flexible circuit board. In this way, at least part of the force applied by the first magnet in the magnet assembly to the flexible circuit board can be offset by the force applied by the second magnet in the magnet assembly to the flexible circuit board, so that the force applied by the magnet assembly as a whole to the flexible circuit board is small, thereby making the probability of the flexible circuit board vibrating small.

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figure 1 , Figure 1The terminal device 00 may include: a frame (not marked in the figure), a display screen 02 , a flexible circuit board 03 , a control circuit board (not marked in the figure) and a magnet 04 .

[0031] One side of the frame in the terminal device 00 may be connected to the display screen 02. The display screen 02 may include: a display panel 02a and a driving component 02b bound and connected to the display panel 02a.

[0032] One end of the flexible circuit board 03 in the terminal device 00 can be connected to the driving component 02b, and the other end of the flexible circuit board 03 in the terminal device 00 can be connected to the control circuit board (also commonly referred to as the main board). It should be noted that after the end of the flexible circuit board 03 away from the driving component 02b is connected to the control circuit board, the control circuit board can sequentially send a driving signal to the pixels in the display panel 02a through the flexible circuit board 03 and the driving component 02b, so that the pixels in the display panel 02a can emit light outward, thereby enabling the display panel 02a to display the corresponding picture.

[0033] The magnet 04 in the terminal device 00 can be fixed in the frame, and can be distributed on the side of the flexible circuit board 03 away from the display panel 02a. Here, the magnet 04 can be used for magnetic connection with a keyboard or a stylus pen.

[0034] However, when the display screen 02 in the terminal device 00 displays images, the alternating current transmitted inside the flexible circuit board 03 generates an alternating electromagnetic force. Since the magnet 04 is distributed on the side of the flexible circuit board 03 away from the display panel 02a, the flexible circuit board 03 is easily vibrated under the action of the magnet 04 and the alternating electromagnetic force generated inside the flexible circuit board 03, which makes the flexible circuit board 03 easily generate noise due to vibration, and further leads to low reliability of the terminal device 00.

[0035] The present application embodiment provides a terminal device. To more clearly understand the structure of the terminal device, please refer to Figure 2 , Figure 2 is a schematic diagram of the structure of a terminal device provided in an embodiment of the present application. The terminal device may be a mobile phone, a tablet computer, or a laptop computer, etc. Figure 2 The terminal device 000 may include: a frame 100 , a display screen 200 , a flexible circuit board 300 and a magnet assembly 400 .

[0036] Please refer to Figure 3 , Figure 31 is a schematic diagram of the back of a display screen in a terminal device provided in an embodiment of the present application. The display screen 200 may include: a display panel 201, and a driving component 202 bound and connected to the display panel 201. For example, the driving component 202 may be bound and connected to the display panel 201 at an edge position on the front side of the display panel 201. After the driving component 202 is bound and connected to the display panel 201, the driving component 202 may be bent to the back side of the display panel 201, so that the overall screen-to-body ratio of the display screen 200 is higher.

[0037] One side of the frame 100 in the terminal device 000 may be connected to the display panel 201 in the display screen 200 , and the frame 100 may have an accommodating space K. The driving component 202 in the display screen 200 may be located in the accommodating space K.

[0038] The flexible circuit board 300 in the terminal device 000 can be located in the accommodation space K of the frame 100, and one end of the flexible circuit board 300 can be connected to the driving component 202. It should be noted that the end of the flexible circuit board 300 away from the driving component 202 can be connected to the control circuit board (i.e., the main board) in the terminal device. The control circuit board can sequentially send a driving signal to the pixels in the display panel 201 through the flexible circuit board 300 and the driving component 202, so that the pixels in the display panel 201 can emit light outward, thereby enabling the display panel 201 to display the corresponding picture.

[0039] The magnet assembly 400 in the terminal device 000 can be fixed in the accommodation space K of the frame 100, and the magnet assembly 400 can be distributed on the side of the flexible circuit board 300 away from the display panel 201. Here, the magnet assembly 400 may include: at least one first magnet 401 and at least one second magnet 402 distributed at intervals. Among them, the magnetism of the first magnet 401 in the magnet assembly 400 toward the side of the flexible circuit board 300 can be opposite to the magnetism of the second magnet 402 in the magnet assembly 400 toward the flexible circuit board 300. For example, the accommodation space K of the frame 100 is provided with mounting grooves corresponding to the multiple magnets in the magnet assembly 400, and each magnet (that is, the first magnet 401 or the second magnet 402) can be assembled in the corresponding mounting groove by adhesive.

[0040] In this case, since the magnet assembly 400 is provided in the terminal device 000, and the magnetism of the first magnet 401 in the magnet assembly 400 toward the side of the flexible circuit board 300 can be opposite to the magnetism of the second magnet 402 in the magnet assembly 400 toward the flexible circuit board 300. Therefore, during the process of the display screen 200 in the terminal device 000 displaying the picture, even if the alternating current is still transmitted in the flexible circuit board 300 to generate the alternating electromagnetic force, it can be ensured that the force applied by the first magnet 401 in the magnet assembly 400 to the flexible circuit board 300 is opposite to the force applied by the second magnet 402 in the magnet assembly 400 to the flexible circuit board 300. For example, due to the electromagnetic force generated inside the flexible circuit board 300, the first magnet 401 in the magnet assembly 400 applies an attractive force to the flexible circuit board 300, and the second magnet 402 in the magnet assembly 400 can apply a repulsive force to the flexible circuit board 300. For another example, due to the electromagnetic force generated inside the flexible circuit board 300, the first magnet 401 in the magnet assembly 400 applies a repulsive force to the flexible circuit board 300, while the second magnet 402 in the magnet assembly 400 can apply an attractive force to the flexible circuit board 300. In this way, at least part of the force applied by the first magnet 401 in the magnet assembly 400 to the flexible circuit board 300 can be offset by the force applied by the second magnet 402 in the magnet assembly 400 to the flexible circuit board 300, so that the force applied by the magnet assembly 400 as a whole to the flexible circuit board 300 is smaller, thereby making the probability of the flexible circuit board 300 vibrating smaller. In this way, the probability of the flexible circuit board 300 generating noise due to vibration can be effectively reduced, thereby improving the reliability of the terminal device 000.

[0041] In summary, a terminal device provided in an embodiment of the present application includes: a frame, a display screen, a flexible circuit board and a magnet assembly. Since a magnet assembly is provided in the terminal device, and the magnetism of the first magnet in the magnet assembly toward the side of the flexible circuit board can be opposite to the magnetism of the second magnet in the magnet assembly toward the flexible circuit board. Therefore, in the process of displaying the picture on the display screen in the terminal device, even if the alternating current is still transmitted in the flexible circuit board to generate an alternating electromagnetic force, it can also be ensured that the force applied by the first magnet in the magnet assembly to the flexible circuit board is opposite to the force applied by the second magnet in the magnet assembly to the flexible circuit board. In this way, at least part of the force applied by the first magnet in the magnet assembly to the flexible circuit board can be offset by the force applied by the second magnet in the magnet assembly to the flexible circuit board, so that the force applied by the magnet assembly as a whole to the flexible circuit board is small, thereby making the probability of the flexible circuit board vibrating small. In this way, the probability of the flexible circuit board generating noise due to vibration can be effectively reduced, thereby improving the reliability of such a terminal device.

[0042] In the examples of this application, please refer to Figure 4 , Figure 4 4 is a schematic diagram of the back of another display screen in a terminal device provided in an embodiment of the present application. At least one first magnet 401 and at least one second magnet 402 in the magnet assembly 400 can be arranged at intervals in a first direction A1. Here, the first direction A1 refers to: parallel to the width direction of the flexible circuit board 300.

[0043] Optional, such as Figure 4 As shown, the number of the first magnets 401 in the magnet assembly 400 can be multiple, and there are two first magnets 401 among the multiple first magnets 401, which are respectively: the two magnets distributed on the outermost sides in the first direction A1 in the magnet assembly 400, and at least one second magnet 402 can be distributed between the two first magnets 401. In this case, in the process of generating electromagnetic force in the flexible circuit board 300, the two first magnets 401 in the magnet assembly 400 can simultaneously apply forces to the two side edges of the flexible circuit board 300 that are arranged oppositely in the first direction A1. In this process, the second magnet 402 in the magnet assembly 400 can apply opposite forces to the central area of ​​the flexible circuit board 300 located between the two side edges. In this way, it can be ensured that the force applied by the magnet assembly 400 to the flexible circuit board 300 is relatively uniform, and the probability of vibration of the flexible circuit board 300 is further reduced.

[0044] In the embodiment of the present application, in the magnet assembly 400, a plurality of first magnets 401 and at least one second magnet 402 may be arranged alternately in the first direction A1. In this way, in the process of generating electromagnetic force in the flexible circuit board 300, the uniformity of the force applied by the magnet assembly 400 to the flexible circuit board 300 may be further improved, thereby further reducing the probability of vibration of the flexible circuit board 300.

[0045] It should be noted that the number of the second magnets in the magnet assembly 400 may be one, or the number of the second magnets in the magnet assembly 400 may be two or more. To this end, the present application embodiment takes the following two optional implementations as examples for schematic illustration:

[0046] The first optional implementation method is Figure 4As shown, when the number of the second magnet 402 in the magnet assembly 400 is one and the number of the first magnet 401 in the magnet assembly 400 is two, the second magnet 402 in the magnet assembly 400 can be located between the two first magnets 401 in the magnet assembly 400, and the distance d1 between the second magnet 402 in the magnet assembly 400 and the two first magnets 401 in the magnet assembly 400 can be equal. In this way, the force applied by the second magnet 402 to the flexible circuit board 300 and the force applied by the two first magnets 401 to the flexible circuit board 300 are evenly distributed, further improving the uniformity of the force applied by the magnet assembly 400 to the flexible circuit board 300.

[0047] For the second optional implementation, please refer to Figure 5 , Figure 5 It is a schematic diagram of the back of a display screen in another terminal device provided in an embodiment of the present application. When the number of the second magnets 402 in the magnet assembly 400 is two or more, and the number of the first magnets 401 in the magnet assembly 400 is three or more, a first magnet 401 may be distributed between two adjacent second magnets 402 in the magnet assembly 400, and the distance d2 between any two adjacent first magnets 401 and second magnets 402 in the magnet assembly 400 may be equal. In this case, the force applied by each second magnet 402 to the flexible circuit board 300 and the force applied by each first magnet 401 to the flexible circuit board 300 are uniformly distributed, further improving the uniformity of the force applied by the magnet assembly 400 to the flexible circuit board 300.

[0048] In the embodiment of the present application, the total area of ​​the end surfaces of the first magnets 401 in the magnet assembly 400 facing the end of the flexible circuit board 300 may be equal to the total area of ​​the end surfaces of the second magnets 402 in the magnet assembly 400 facing the end of the flexible circuit board 300 .

[0049] For example, when the number of second magnets 402 in the magnet assembly 400 is one and the number of first magnets 401 in the magnet assembly 400 is two, the total area of ​​the end faces of each first magnet 401 in the magnet assembly 400 facing one end of the flexible circuit board 300 is: the sum of the areas of the end faces of the two first magnets 401 facing one end of the flexible circuit board 300, and the total area of ​​the end faces of each second magnet 402 in the magnet assembly 400 facing one end of the flexible circuit board 300 is: the area of ​​the end face of this second magnet 402 facing one end of the flexible circuit board 300.

[0050] In this way, it can be ensured that the force applied by the first magnet 401 in the magnet assembly 400 to the flexible circuit board 300 is completely offset by the force applied by the second magnet 402 in the magnet assembly 400 to the flexible circuit board 300, thereby ensuring that the flexible circuit board 400 will not move in the direction toward the magnet assembly 400 or in the direction away from the magnet assembly 400, so that the flexible circuit board 300 will not vibrate when the display screen 200 displays the image.

[0051] In the examples of this application, please refer to Figure 4 and Figure 5 The magnet assembly 400 may be distributed on a side of the flexible circuit board 300 close to the driving assembly 202 .

[0052] Optional, please refer to Figure 4 and Figure 5 The orthographic projection of at least one first magnet 401 in the magnet assembly 400 on the display panel 201 may overlap with the orthographic projection of the flexible circuit board 300 on the display panel 201, and / or the orthographic projection of at least one second magnet 402 in the magnet assembly 400 on the display panel 201 may overlap with the orthographic projection of the flexible circuit board 300 on the display panel 201.

[0053] In the present application, the magnetism of the first magnet 401 in the magnet assembly 400 toward the side of the flexible circuit board 300 may be one of the N-pole magnetism and the S-pole magnetism, and the magnetism of the second magnet 402 in the magnet assembly 400 toward the flexible circuit board 300 may be the other of the N-pole magnetism and the S-pole magnetism. This embodiment of the present application is not limited to this.

[0054] In summary, a terminal device provided in an embodiment of the present application includes: a frame, a display screen, a flexible circuit board and a magnet assembly. Since a magnet assembly is provided in the terminal device, and the magnetism of the first magnet in the magnet assembly toward the side of the flexible circuit board can be opposite to the magnetism of the second magnet in the magnet assembly toward the flexible circuit board. Therefore, in the process of displaying the picture on the display screen in the terminal device, even if the alternating current is still transmitted in the flexible circuit board to generate an alternating electromagnetic force, it can be ensured that the force applied by the first magnet in the magnet assembly to the flexible circuit board is opposite to the force applied by the second magnet in the magnet assembly to the flexible circuit board. In this way, at least part of the force applied by the first magnet in the magnet assembly to the flexible circuit board can be offset by the force applied by the second magnet in the magnet assembly to the flexible circuit board, so that the force applied by the magnet assembly as a whole to the flexible circuit board is small, thereby making the probability of the flexible circuit board vibrating small. In this way, the probability of the flexible circuit board generating noise due to vibration can be effectively reduced, thereby improving the reliability of such a terminal device.

[0055] An embodiment of the present application also provides a terminal system, which may include: any of the above-mentioned terminal devices, and a functional component magnetically connected to the terminal device.

[0056] Exemplarily, the functional component may be a component such as a stylus or a keyboard that enables the terminal device to have a specific function. Here, the functional component may have a magnetic member that cooperates with the magnetic assembly in the terminal device, and the functional component can be magnetically connected to the terminal device through the magnetic cooperation of the magnetic member and the magnetic assembly. For example, the magnetic member may include at least one third magnet and at least one fourth magnet, and the at least one third magnet and at least one fourth magnet are arranged in the same manner as the at least one first magnet and at least one second magnet in the above embodiment. Here, at least one third magnet can be magnetically cooperated with at least one first magnet, and at least one fourth magnet can be magnetically cooperated with at least one second magnet.

[0057] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0058] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
