Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Currently, a stylus may be detachably connected to a housing in a terminal device in a magnetic manner. And after the touch pen is connected with the shell of the terminal equipment, the terminal equipment can carry out wireless charging on the touch pen. However, the housing in the terminal device is generally made of a metal material, and electromagnetic waves emitted from the electromagnetic transmitting coil in the terminal device are easily shielded by the housing when the terminal device wirelessly charges the stylus pen. For this reason, an opening is required to be provided in the housing at a position where the electromagnetic transmitting coil is integrated, so that electromagnetic waves emitted from the electromagnetic transmitting coil can pass through the opening and then be emitted to the stylus pen, thereby enabling the stylus pen to perform wireless charging.

In order to ensure that the housing in the terminal device can effectively protect the internal integrated device, a plastic part which can not shield electromagnetic waves needs to be arranged in the opening. However, the plastic member disposed in the opening is generally formed by injection molding the housing. The plastic part formed in the opening hole by adopting the injection molding process has lower yield and higher cost. Therefore, the yield of the terminal equipment integrated with the electromagnetic transmitting coil is low at present, and the manufacturing cost is high.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a terminal device according to an embodiment of the present application, and fig. 2 is a schematic diagram of the terminal device shown in fig. 1 on the other side. The terminal equipment can be equipment capable of wirelessly charging the touch pen, such as a mobile phone, a tablet personal computer, a notebook personal computer or an electronic paper book. Fig. 1 is a schematic illustration of a terminal device as a tablet computer. The terminal device 000 may include: a housing assembly 100. Here, the stylus can be detachably connected with the terminal device 000 at the position a of the housing assembly 100, so that the terminal device can charge the stylus after the stylus is connected with the terminal device 000.

For a clearer view of the structure of the housing assembly 100 in the terminal device 000, please refer to fig. 3, fig. 3 being a partial schematic view of the housing in the terminal device shown in fig. 1. The housing assembly 100 in the terminal device 000 may have a receiving chamber 100a and an opening 100b communicating with the receiving chamber 100 a. This opening 100b is the opening 100b in the terminal device 000 for wirelessly charging the stylus.

By way of example, the housing assembly 100 may include: a side plate and a bottom plate connected with one side of the side plate. Wherein, the side plate may be annular, and the accommodating cavity 100a of the housing assembly 100 means: a semi-enclosed space surrounded by the side plate and the bottom plate. As shown in fig. 2, the terminal device 000 may further include: a display 400, the display 400 being connectable to the other side of the side panel in the housing assembly 100. Here, after the display screen 400 is connected to the other side of the side plate, the display screen 400 may enclose the receiving chamber 100a of the housing assembly 100 into a closed space. It should be further noted that fig. 3 is schematically illustrated by taking the case that the opening 100b is located on a side plate in the housing assembly 100, and in other possible line-of-sight manners, the opening 100b may be located on a bottom plate in the housing assembly 100. The embodiments of the present application are not limited in this regard.

In order to make it possible to more clearly see the structure distributed inside the housing chamber 100 a. Referring to fig. 4, fig. 4 is an internal partial schematic view of the terminal device shown in fig. 1. The terminal device 000 may further include: a support assembly 200 and a coil assembly 300.

In order to be able to see the assembly relationship of the housing assembly 100, the support assembly 200 and the coil assembly 300 in the terminal device 000, reference is made to fig. 4 and 5, fig. 5 being a partial schematic view of the terminal device shown in fig. 4 on the other side. A portion of the support assembly 200 is positioned within the receiving cavity 100a and may be used to carry the coil assembly 300, and another portion of the support assembly 200 may be positioned within the aperture 100b. Here, the support member 200 may be fixed in the receiving chamber 100a by being assembled with the housing member 100, and the support member 200 may be made of a material that does not affect the transmission of electromagnetic waves, for example, the material of the support member 200 may be a plastic material.

In the present application, as shown in fig. 4 and 5, a side of the coil assembly 300 facing the opening 100b of the housing assembly 100 has an electromagnetic wave emitting surface P. The coil assembly 300 is here an electromagnetic transmitting coil integrated within the terminal device 000.

In this case, when the stylus pen is placed at the position a of the terminal device 000, the stylus pen may be connected with the housing assembly 100 of the terminal device 000, and the electromagnetic receiving coil in the stylus pen may be opposite to the coil assembly 300 in the terminal device 000. In this way, the terminal device 000 can emit electromagnetic waves through the electromagnetic wave emitting surface P of the coil assembly 300, and since the electromagnetic wave emitting surface P of the coil assembly 300 faces the opening 100b of the housing assembly 100 and the support assembly 200 for carrying the coil assembly 300 is made of a material that does not affect the transmission of electromagnetic waves, the electromagnetic waves emitted from the electromagnetic wave emitting surface P of the coil assembly 300 can be emitted through the support assembly 200 to the electromagnetic receiving coil in the stylus through the opening 100b of the housing assembly 100 to achieve wireless charging of the stylus.

In the embodiment of the present application, since the support assembly 200 is fixed in the accommodating cavity 100a by assembling with the housing assembly 100, it is not necessary to separately use an injection molding process to form a plastic part by injection molding in the opening of the housing assembly, and it is not necessary to separately manufacture a structure for assembling the coil assembly in the housing assembly. In this way, the process difficulty of the terminal device 000 integrated with the coil assembly 300 can be effectively simplified, and thus the yield of the terminal device 000 can be improved, and the manufacturing cost of the terminal device 000 can be reduced.

In addition, in the process of assembling the support assembly 200 and the housing assembly 100, if the preparation error of any one of the support assembly 200 and the housing assembly 100 is larger, the assembly can be continued after only replacing the assembly with the larger preparation error, and the two assemblies are not required to be replaced at the same time, so that the manufacturing cost of the terminal device 000 can be further reduced.

In summary, the present application provides a terminal device, including: a housing assembly, a support assembly, and a coil assembly. The supporting component is fixed in the accommodating cavity in a mode of being assembled with the shell component, after the supporting component is assembled with the shell component, the protruding structure in the supporting component is located in the opening of the shell component, and the supporting piece in the supporting component can support the coil component. Therefore, the plastic piece is not required to be formed in the opening of the shell component by injection molding through an injection molding process, and a structure for assembling the coil component is not required to be manufactured in the shell component. And when the support component and the shell component are assembled in a deviation way, the support component and the shell component can be disassembled to be assembled again. Therefore, the process difficulty of the terminal equipment integrated with the coil assembly can be effectively simplified, the yield of the terminal equipment can be improved, and the manufacturing cost of the terminal equipment can be reduced. In addition, in the process of assembling the supporting component and the shell component, if the preparation error of any one of the supporting component and the shell component is larger, the assembly can be continued after only the component with larger preparation error is required to be singly replaced, the two components are not required to be simultaneously replaced, and the manufacturing cost of the terminal equipment can be further reduced.

In an embodiment of the present application, referring to fig. 4 and 5, the support assembly 200 in the terminal device 000 may include: the support member body 201 is fixed in the accommodating chamber 100a, and the protrusion structure 202 is fixedly connected with the support member body 201, the support member body 201 in the support assembly 200 has a mounting groove U, and the protrusion structure 202 in the support assembly 200 may be positioned in the opening 100b of the housing assembly 100. Here, after the support assembly 200 is assembled with the housing assembly 100, the protrusion structure 202 in the support assembly 200 may be positioned in the opening 100b of the housing assembly 100, and the support body 201 in the support assembly 200 may support the coil assembly 300.

In order to more clearly see the assembly relationship between the support assembly 200 and the coil assembly 300, please refer to fig. 4 and 6, and fig. 6 is a schematic diagram illustrating the assembly of the support assembly and the coil assembly according to an embodiment of the present application. At least part of the coil assembly 300 in the terminal device 000 is located in the mounting groove U of the support body 201. Here, the electromagnetic wave emitting surface P of the coil assembly 300 may face the protrusion structure 202 in the support assembly 200.

By way of example, since the electromagnetic wave emitting surface P of the coil assembly 300 faces the protrusion structure 202 in the supporting assembly 200 and the protrusion structure 202 is disposed in the opening 100b of the housing assembly 100, the electromagnetic wave emitted from the electromagnetic wave emitting surface P of the coil assembly 300 can pass through the opening 100b of the housing assembly 100 through the protrusion structure 202, so that the electromagnetic wave emitted from the electromagnetic wave emitting surface P can be directed to the electromagnetic receiving coil in the stylus pen to realize wireless charging of the stylus pen.

In the related art, since plastic parts in openings of a housing in a terminal device are formed by an injection molding process, the housing of the terminal device is generally made of a metal material. Therefore, the color difference between the surface color of the plastic part and the color of the shell is large, so that the appearance of the terminal equipment is poor.

In the embodiment of the present application, please refer to fig. 7, fig. 7 is a partial schematic diagram of another terminal device provided in the embodiment of the present application. The side of the raised structure 202 in the support assembly 200 facing away from the support body 201 may have a decorative coating 203. Here, the color of the decorative coating 203 may be consistent with the color of the outer surface of the housing assembly 100, so that the appearance of the terminal device 000 is better. For example, prior to assembly of the support assembly 200 with the housing assembly 100, the raised structures 202 in the support assembly 200 may be painted separately such that the side of the raised structures 202 facing away from the support body 201 may form the decorative coating 203.

Alternatively, as shown in FIG. 7, the side of the decorative coating 203 facing away from the raised structure 202 may be flush with the outer surface of the housing assembly 100. In this way, it is ensured that the outer surface of the housing assembly 100 of the terminal device 000 is relatively flush to further enhance the external appearance of the terminal device 000.

In the embodiment of the present application, please refer to fig. 8, fig. 8 is an internal partial schematic diagram of the terminal device shown in fig. 7. The coil assembly 300 in the terminal device 000 may include: a coil body 301 located in the mounting groove U, and a flexible circuit board 302 (english: flexible Printed Circuit; abbreviated as FPC) connected to the coil body 301, the FPC302 may be located outside the mounting groove U. In this way, an operator can more conveniently install the coil assembly 300 in the accommodating chamber 100a of the housing assembly 100.

Illustratively, the FPC302 may conform to the interior walls of the receiving cavity 100a of the housing assembly 100. For example, the FPC302 may be bonded to the inner wall of the housing chamber 100a of the housing assembly 100 by an adhesive layer. In this way, the internal structure of the terminal device 000 is effectively simplified without integrating a fixing bracket for supporting the FPC302 in the housing chamber 100a, so as to further reduce the manufacturing cost of the terminal device 000.

The FPC302 is attached to the inner wall of the housing chamber 100a of the housing assembly 100. Therefore, the FPC302 may be stably fixed in the accommodating chamber 100a, so as to ensure that the coil assembly 300 can be stably mounted in the accommodating chamber 100 a. In this way, even if the terminal device 000 receives an external force, it is ensured that the position of the coil assembly 300 does not change.

In the embodiment of the present application, please refer to fig. 8, 9 and 10, fig. 9 is a sectional view of the terminal device shown in fig. 7 at the coil assembly, and fig. 10 is a schematic structural view of another housing assembly provided in the embodiment of the present application. The housing assembly 100 in the terminal device 000 may include: a first housing 101, and a second housing 102 fixedly connected to the first housing 101. The second housing 102 has a relief groove B1 for assembling the support assembly 200, and a positioning groove B2 provided adjacent to the relief groove B1.

In this application, as shown in fig. 8, the first housing 101 in the housing assembly 100 may be formed by using a stamping process, and the first housing 101 and the second housing 102 may be fixedly connected by means of an adhesive. Here, the first housing 101 is not manufactured by CNC processing, which is relatively costly, but is manufactured by a relatively low-cost stamping process, so as to further reduce the manufacturing cost of the terminal device 000. When the first housing 101 is formed by a stamping process, the first housing 101 may include: a ring-shaped metal side plate 101a, and a metal bottom plate 101b fixedly connected to the metal side plate 101 a. One part of the second housing 102 in the housing assembly 100 needs to be fixedly connected to the inner side surface of the metal side plate 101a, and the other part needs to be fixedly connected to the surface of the metal bottom plate 101b, which is close to the metal side plate 101 a.

Optionally, the shape of the avoidance groove B1 of the second housing 102 may be matched with the shape of the support assembly 200, so that an operator can determine the placement position of the support assembly 200 more conveniently when installing the support assembly 200, thereby fixing the support assembly 200 to the housing assembly 100 with high efficiency.

By way of example, the relief groove B1 of the second housing 102 may be a through groove. In this way, after the support assembly 200 is mounted in the escape groove B1, the support assembly 200 can be bonded to the inner side surface of the metal side plate 101a of the first housing 101 in the escape groove B1. For example, the support assembly 200 may be adhered to the inner side surface of the metal side plate 101a through the first adhesive layer P1.

In the present application, the FPC302 may include: a first portion 302a fixed to a side of the second housing 102 facing away from the first housing 101, and a second portion 302B fixed in a positioning groove B2 of the second housing 102. As an example, as shown in fig. 9, the first portion 302a in the FPC302 may be bonded to a side of the first second housing 102a facing away from the first housing 101 through the second bonding layer P2. The second portion 302B of the FPC302 may be bonded to the bottom surface of the positioning groove B2 through the third adhesive layer P3.

Alternatively, the positioning groove B2 of the second housing 102 may be a through groove. In this way, the second portion 302B in the FPC302 can be bonded to the metal base plate 101B in the first housing 101 through the third bonding layer P3 in the positioning groove B2. Here, when the second portion 302b of the FPC302 is directly adhered to the metal base 101b through the third adhesive layer P3, heat generated from the FPC302 may be transferred to the metal base 101b and dissipated by the metal base 101b when the coil assembly 300 is in operation, and thus the operating temperature of the coil assembly 300 may be reduced.

In this embodiment, as shown in fig. 8, a side of the second housing 102 facing away from the first housing 101 may have a positioning protrusion K for positioning the first portion 302a of the FPC 302. By way of example, when the second housing 102 has the positioning protrusion K on the side facing away from the first housing 101, during the process of installing the FPC302 by the operator, the orientation and position of the FPC302 in the housing cavity 100a may be determined by the positioning protrusion K, so that the FPC302 may be efficiently and fixedly connected with the housing assembly 100.

Alternatively, the number of the positioning protrusions K may be plural, the plurality of positioning protrusions K may be divided into two groups, and the first portion 302a of the FPC302 may be located between the two groups of positioning protrusions K. In this way, by observing the positions of the two sets of positioning projections K, the operator can quickly determine the orientation and position of the FPC302 in the housing chamber 100 a.

As an example, as shown in fig. 10, each set of positioning projections may include one positioning projection K, so that the number of positioning projections K provided on a side of the second housing 102 facing away from the first housing 101 may be two, and the first portion 302a of the FPC302 may be located between the two positioning projections K. In this way, during the process of installing the FPC302 by the operator, the orientation and position of the FPC302 in the accommodation chamber 100a can be more efficiently determined by the positioning of the two positioning projections K. Illustratively, the FPC302 may be elongated in shape, and the distance between the two positioning protrusions K may be slightly greater than the width of the FPC302, so that an operator may quickly place the first portion 302a of the FPC302 between the two positioning protrusions K to determine the orientation and position of the FPC302 in the receiving cavity 100 a.

In the embodiment of the present application, please refer to fig. 8 and fig. 11, fig. 11 is a schematic partial structure of still another terminal device provided in the present application. The terminal device 000 may further include: a control circuit board 500 fixed to a side of the second housing 102 facing away from the first housing 101, the control circuit board 500 being electrically connected to a side of the second portion 302b of the FPC302 facing away from the first housing 101.

Here, the receiving chamber 100a in the housing assembly 100 may be integrated with a sensor, which may be communicatively connected with the control circuit board 500. The sensor may be used to detect whether the stylus is placed on the terminal device 000 and transmit the detected information to the control circuit board 500. Since the second portion 302b of the FPC302 may be electrically connected to the control circuit board 500. Accordingly, the control circuit board 500 may control the coil assembly 300 to emit electromagnetic waves after the control circuit board 500 detects that the stylus pen is placed at the terminal device 000 through the sensor; the control circuit board 500 may control the coil assembly 300 to stop operating after detecting that the stylus pen is not placed in the terminal device 000 through the sensor.

It should be noted that, as shown in fig. 8, since there may be a certain distance between the second portion 302b of the FPC302 and the control circuit board 500, the spring 600 may be disposed on a side of the control circuit board 500 close to the second portion 302b of the FPC302, and it is required to ensure that the second portion 302b of the FPC302 has a power receiving member disposed opposite to the spring 600. In this way, after the control circuit board 500 and the FPC302 are both fixed in the accommodating cavity 100a, the elastic sheet 600 on the control circuit board 500 can be electrically connected with the electrical connector disposed on the second portion 302b of the FPC302, so as to ensure that the control circuit board 500 can be electrically connected with the FPC302 normally.

In the embodiment of the present application, please refer to fig. 12, fig. 12 is a schematic structural diagram of a terminal system provided in the embodiment of the present application. The terminal system 001 may include: the terminal device 000 and the stylus 002, the terminal device 000 may be the terminal device 000 in the above embodiments, for example, the terminal device 000 shown in fig. 1, 2, 4, 7, 8, 10 or 11, and the stylus 001 may be detachably connected with the housing assembly 100 in the terminal device 000 at the opening 100a of the terminal device 000. For example, magnets capable of applying a magnetic attraction force to the stylus 001 may be provided at both sides of the opening 100a of the terminal device 000 so that the stylus 001 can be connected to the terminal device 000 by means of the magnetic attraction force.
