Description

Wearable electronic device including a battery support plate

[0001] Various embodiments disclosed in this document relate to a wearable electronic device including a battery support plate.

[0002] With technological advancements, wearable electronic devices (e.g., smartwatches) are becoming increasingly widespread, following user terminals like smartphones and tablets. Wearable electronic devices may include smartwatches, which are worn on a user's body (e.g., wrist) and perform various functions.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0004] A wearable electronic device, such as a smartwatch, may include a housing that forms at least a portion of the wearable electronic device's exterior. A bracket for securing electronic components, a printed circuit board, and a battery may be disposed within the housing. The battery may be disposed within the bracket and adjacent to a shield can disposed on the printed circuit board. Components containing conductive materials, such as the battery and the shield can, may generate capacitance depending on their proximity, and the capacitance may generate a parasitic resonant frequency at a specific frequency. The antenna resonant frequency of the wearable electronic device may be designed to take the parasitic resonant frequency into account. For example, the antenna resonant frequency may be set to transmit or receive a wireless signal considering the parasitic resonant frequency value. However, if the parasitic resonant frequency fluctuates, antenna performance may deteriorate due to the change in the set antenna resonant frequency. For example, the battery may experience swelling, which occurs depending on the state of charge. In such cases, the gap between the battery and the shield can fluctuates due to battery swelling, which can alter the parasitic resonant frequency. Consequently, antenna performance may deteriorate as the set antenna resonant frequency fluctuates.

[0005] Various embodiments of the present disclosure can provide a wearable electronic device including a support plate configured such that the value of a parasitic resonant frequency is maintained constant.

[0006] Various embodiments may provide a wearable electronic device including a support plate electrically connected to a wireless communication circuit of a printed circuit board and capable of operating as an antenna radiator at a predetermined resonant frequency band.

[0067] FIGS. 5A and 5B are exploded perspective views of a battery, a support plate, a bracket, and a printed circuit board of a wearable electronic device according to an embodiment of the present disclosure. FIG. 6 is a plan view of a printed circuit board and a first shield can according to an embodiment of the present disclosure. FIG. 7 is a cross-sectional view taken along line AA of FIG. 5B.

[0068] According to one embodiment, as illustrated in FIGS. 5A and 5B , a wearable electronic device (e.g., the electronic device (101) of FIG. 1 , the electronic device (200) of FIG. 2A , and / or the electronic device (400) of FIG. 4 ) may include a bracket (520) (e.g., the support member (460) of FIG. 4 ), a battery (540) (e.g., the battery (470) of FIG. 4 ), a support plate (530), and a printed circuit board (510) (e.g., the printed circuit board (480) of FIG. 4 ) disposed inside a housing (e.g., the housing (210) of FIG. 2 and / or the side bezel structure (410) of FIG. 4 ). In one embodiment, the battery (540), the support plate (530), and the printed circuit board (510) may be sequentially disposed with respect to the Z-axis of FIG. 5A .

[0069] In one embodiment, referring to FIGS. 5A and 5B, the bracket (520) may include a front surface (520A) (e.g., a surface facing the +Z direction in FIG. 5A), a back surface (520B) opposite the front surface (520A) (e.g., a surface facing the -Z direction in FIG. 5A), and a side surface (520C) surrounding a space between the front surface (520A) and the back surface (520B). In one embodiment, the bracket (520) may be disposed between a display (e.g., the display module (160) of FIG. 1, the display (220) of FIG. 4) and a printed circuit board (510). The display may be disposed to face the front surface (520A) of the bracket (520). For example, the display may be disposed on the front surface (520A) of the bracket (520). The printed circuit board (510) may be placed toward the back surface (520B) of the bracket (520). For example, the printed circuit board (510) may be placed on the back surface (520B) of the bracket (520).

[0070] In one embodiment, referring to FIG. 5A, the bracket (520) may include an internal space (5201). In one embodiment, the internal space (5201) may be an opening shape extending from the front surface (520A) of the bracket (520) toward the back surface (520B). In one embodiment, the battery (540) and the support plate (530) may be at least partially disposed in the internal space (5201) of the bracket (520). In one embodiment, the printed circuit board (510) may be disposed on the back surface (520B) of the bracket (520) such that at least a portion of the printed circuit board (510) may be disposed in the internal space (5201) of the bracket (520). For example, as illustrated in 7a described below, an electronic component (511) placed on a first surface (510A) of a printed circuit board (510) and a first shield can (501) covering the electronic component (511) may be positioned, at least in part, in an internal space (5201) of a bracket (520).

[0071] In one embodiment, referring to FIGS. 5A and 5B, a support plate (530) including a conductive material may be placed in the internal space (5201) of the bracket (520). In one embodiment, the support plate (530) may support a battery (540) in the internal space (5201) of the bracket (520). For example, the battery (540) may be supported by the support plate (530) and positioned between a display located on the front side (520A) of the bracket (520) and the support plate (530).

[0072] In one embodiment, the support plate (530) may include a conductive material to diffuse heat generated from components adjacent to the support plate (530), such as a battery (540), a first shield can (501), a printed circuit board (510), and / or an electronic component (511).

[0073] In one embodiment, referring to FIG. 5A, the support plate (530) may include a support portion (531) on which the battery (540) is mounted, and a coupling portion (e.g., a first coupling portion (532) and / or a second coupling portion (533)) extending from the support portion (531) and fixed to the bracket (520). In one embodiment, the battery (540) may be adhered to the support portion (531) of the support plate (530) via an adhesive member (P) (e.g., an adhesive tape). In one embodiment, the coupling portions (532, 533) may be fixed to the front surface (520A) of the bracket (520).

[0074] In one embodiment, referring to FIGS. 5A and 5B, the coupling portions (532, 533) may include a first coupling portion (532) extending from one end of the support portion (531) and fixed to the front surface (520A) of the bracket (520), and a second coupling portion (533) extending from the other end of the support portion (531) and fixed to the front surface (520A) of the bracket (520). The first coupling portion (532) and the second coupling portion (533) may face each other. In one embodiment, the first coupling portion (532) and the second coupling portion (533) may include a first portion (5321, 5331) extending at least partially substantially perpendicular to the support portion (531), and a second portion (5322, 5332) bent from the first portion to be parallel to the support portion (531) and positioned on the front surface (520A) of the bracket (520). In one embodiment, the first coupling portion (532) and the second coupling portion (533) may include a hole (H) through which a fixing member (F) (e.g., a screw or a screw) passes. In one embodiment, the hole (H) may be formed in the second portion (5322) of the first coupling portion (532) and the second portion (5332) of the second coupling portion (533), respectively. The fixing member (F) can pass through the hole of the first connecting portion (532) and the hole formed in the front surface (520A) of the bracket (520), and another fixing member (F) can pass through the hole of the second connecting portion (533) and another hole formed in the front surface (520A) of the bracket (520). Accordingly, the support plate (530) can be fixed to the bracket (520) through the fixing member (F).

[0075] The shape of the support plate (530) described above is an example, and the support plate (530) can be modified into various shapes. For example, the support plate (630) can be formed into a shape including a support portion (631) and a single connecting portion (632) extending from the support portion (631), as illustrated in FIG. 9A, which will be described later. In addition, the support plate (730) can be formed into a planar shape, as illustrated in FIG. 10, which will be described later. The support plates (630, 730) illustrated in FIGS. 9A and 10 will be described later.

[0076] According to one embodiment, as illustrated in FIGS. 6 and 7, electronic components (511) may be disposed on a first side (510A) (e.g., a side facing the +Z direction in FIG. 7) and a second side (510B) (e.g., a side facing the -Z direction in FIG. 7) of a printed circuit board (510). A first shield can (501) may be disposed on the first side (510A) of the printed circuit board (510) to cover at least a portion of the electronic components (511) disposed on the first side (510A) of the printed circuit board (510). A second shield can (502) may be disposed on the second side (510B) of the printed circuit board (510) to cover at least a portion of the electronic components (511) disposed on the second side (510B) of the printed circuit board (510). In one embodiment, the first shield can (501) and the second shield can (502) may be coupled to the printed circuit board (510) by soldering to the first side (510A) and the second side (510B) of the printed circuit board (510), respectively. In addition, the first shield can (501) and the second shield can (502) may be coupled to the printed circuit board (510) in various ways, such as coupling through clips and sockets.

[0077] In one embodiment, the first shield can (501) and the second shield can (502) may include a conductive material to shield electromagnetic waves generated from the printed circuit board (510) and the electronic component (511) or to disperse heat generated from the electronic component (511) to the surroundings. For example, the first shield can (501) and the second shield can (502) may include a metal material or a material such as graphite. In addition, the first shield can (501) and the second shield can (502) may include various materials that shield electromagnetic waves and have heat conductive properties. In addition, the first shield can (501) and the second shield can (502) may include a material having a certain level of rigidity to protect the electronic component (511) located therein from external impact.

[0078] According to one embodiment, a liquid resin may be injected into the first shield can (501) and the second shield can (502). In one embodiment, the liquid resin may prevent the electronic component (511) from being separated from the printed circuit board (510) and protect the electronic component (511) from external impact when an impact is applied to the wearable electronic device (101, 200, 400). In addition, a liquid thermal interface material (TIM) may be injected into the first shield can (501) and the second shield can (502) to diffuse heat generated from the electronic component (511) to the surroundings.

[0079] According to one embodiment, as illustrated in FIG. 6, an opening (5011) may be formed in the first shield can (501) as a passage through which a liquid heat transfer material is injected. A nozzle through which liquid resin and / or liquid heat transfer material is applied may be inserted into the opening (5011) of the first shield can (501) to apply the liquid resin and / or liquid heat transfer material to a space between the printed circuit board (510) and the first shield can (501). Accordingly, the space between the first shield can (501) and the printed circuit board (510) may be filled with the liquid resin and / or liquid heat transfer material. For example, an opening (not illustrated) may be formed in the second shield can (502) as a passage through which liquid resin and / or liquid heat transfer material is injected.

[0080] According to one embodiment, as illustrated in FIG. 7, electromagnetic waves generated from electronic components (511) disposed on a first surface (510A) of a printed circuit board (510) may be emitted to the outside of the first shield can (501) through an opening (5011) of the first shield can (501). Therefore, a shielding member (550) (e.g., a shielding sheet or shielding tape) covering the opening (5011) may be disposed on the first shield can (501). The shielding member (550) may be disposed on the first shield can (501) and may face the support portion (531) of the support plate (530). The shielding member (550) may include a conductive material that shields electromagnetic waves of the electronic components (511). For example, the shielding member (550) may include a metal material or a material such as graphite.

[0081] The above description may be based on the assumption that a liquid resin and / or a liquid heat transfer material is applied to the inside of the first shield can (501) and / or the second shield can (502). However, if the liquid resin and / or the liquid heat transfer material is not applied to the inside of the first shield can (501) and / or the second shield can (502), the opening (5011) may not be formed in the first shield can (501) and / or the second shield can (502). In this case, the shielding member (550) may be omitted from the arrangement structure of the wearable electronic device (101, 200, 400). The following description will be described on the assumption that the shielding member (550) is arranged in the first shield can (501). However, the following description may be substantially equally applied even when the shielding member (550) arranged in the first shield can (501) is omitted.

[0082] In a comparative embodiment, the support plate (530) may be disposed on the front side (520A) of the bracket (520) and may not be located between the battery (540) and the first shield can (501). In this case, the battery (540) may directly face the first shield can (501) and the shielding member (550). Components including conductive materials, such as the battery (540), the first shield can (501), and the shielding member (550), may generate capacitance when disposed adjacent to each other, and the capacitance may generate a parasitic resonance frequency at a specific frequency. The antenna resonance frequency of the wearable electronic device (101, 200, 400) may be designed in consideration of the parasitic resonance frequency. For example, the antenna resonance frequency may be set to transmit or receive a wireless signal in consideration of the parasitic resonance frequency value. However, if the parasitic resonance frequency fluctuates, the antenna performance may deteriorate as the set antenna resonance frequency fluctuates. For example, the battery (540) may experience a swelling phenomenon in which the battery (540) expands depending on the state of charge. In this case, the swelling phenomenon of the battery (540) may cause the gap between the battery (540) and the first shield can (501) and / or the battery (540) and the shielding member (550) to fluctuate, thereby causing the parasitic resonance frequency value to change. Therefore, the antenna performance may deteriorate as the set antenna resonance frequency fluctuates. In addition, the first shield can (501) may be formed in a shape in which a portion facing the battery (540) is open. The open shape may be a shape in which the exterior and interior of the first shield can (501) are connected to each other. In this case, the shape of the shielding member (550) may be deformed as heat generated from the electronic component (511) placed on the first surface (510A) of the printed circuit board (510) is directly transferred to the shielding member (550). Accordingly, as the gap between the shielding member (550) and the battery (540) changes, the parasitic resonant frequency value may change, which may deteriorate the antenna performance.

[0083] In order to prevent the phenomenon of the parasitic resonance frequency of the comparative example described above from changing, as illustrated in FIG. 7, at least a portion of the support plate (530) may be disposed between the battery (540) and the first shield can (501). In this case, the wearable electronic device (101, 200, 400) may generate a parasitic resonance frequency due to the capacitance generated when the support plate (530) including a conductive material and the first shield can (501) and / or the support plate (530) and the shielding member (550) are disposed adjacent to each other. The support plate (530) is fixed to the bracket (520) and may be formed of a metal material to have a certain level of rigidity. Therefore, the gap between the support plate (530) and the shielding member (550) and / or between the support plate (530) and the first shield can (501) may not change. In this case, the value of the parasitic resonance frequency generated by the support plate (530) and the first shield can (501) and / or the support plate (530) and the shielding member (550) may not change. Accordingly, the wearable electronic device can secure the set antenna performance as the set antenna resonance frequency does not change.

[0084] In addition, in one embodiment, the first shield can (501) may not be formed in a shape in which the surface facing the support plate (530) is open. The first shield can (501) may only have an opening (5011) formed in the surface facing the support plate (530) for injecting a liquid resin and / or a liquid heat transfer material. In this case, compared to the comparative embodiment in which the first shield can (501) is formed in an open shape, the amount of heat transferred from the electronic component (511) disposed inside the first shield can (501) to the shielding member (550) may be reduced. Accordingly, the phenomenon in which the shape of the shielding member (550) is deformed due to the heat of the electronic component (511) may be reduced. Accordingly, the value of the parasitic resonance frequency generated due to the adjacent arrangement of the support plate (530) and the shielding member (550) may not change or may change within an error range of the set resonance frequency. Therefore, antenna performance based on the set antenna resonance frequency can be secured.

FIG. 8C is a drawing illustrating a relationship in which the printed circuit board and the support plate of FIG. 7 are electrically connected via pogo pins, according to one embodiment of the present disclosure. FIG. 8D is a drawing illustrating an electrical connection relationship between a printed circuit board and a support plate, according to one embodiment of the present disclosure. FIG. 8E is a drawing of a support plate formed to surround a battery, according to one embodiment of the present disclosure.

[0086] According to one embodiment, the printed circuit board (510) (e.g., the printed circuit board (480) of FIG. 4) may include a wireless communication circuit (e.g., the communication module (190) of FIG. 1) that transmits or receives a wireless signal in at least one frequency band. For example, the wireless communication circuit may include a radio frequency IC (RFIC). The RFIC may transmit a wireless signal (RF signal) processed by the communication module (190) to an antenna radiator (e.g., the housing (210) or the side bezel structure (410)), or transmit a wireless signal received from the antenna radiator to the communication module (190).

[0087] In one embodiment, the support plate (530) may be electrically connected to the printed circuit board (510) and grounded. For example, the printed circuit board (510) on which the wireless communication circuit is arranged may be electrically connected to the support plate (530) in various ways. In one embodiment, referring to FIGS. 8A and 8B, the bracket (520) (e.g., the support member (460) of FIG. 4) may include a conductive portion (5202) formed of a conductive material.

[0088] In one embodiment, referring to FIGS. 8A and 8B, a conduit (e.g., a second connecting hole (521)) may be formed in the conductive portion (5202) into which a fixing member (F) (e.g., a screw, a screw, or a pogo pin (PO) of FIG. 8B) formed of a conductive material (e.g., a metal) is inserted. In one embodiment, a printed circuit board (510) facing the back surface (520B) of the bracket (520) may include a first connecting hole (512) corresponding to the second connecting hole (521) of the bracket (520). The bracket (520) and the printed circuit board (510) may be arranged inside a housing (e.g., the housing (210) of FIG. 2 and / or the side bezel structure (410) of FIG. 4) such that the first connecting hole (512) and the second connecting hole (521) correspond to each other. In one embodiment, the fixing member (F) can be inserted into the first connecting hole (512) of the printed circuit board (510) - the second connecting hole (521) of the bracket (520). In one embodiment, a portion of the support plate (530) (e.g., the second connecting portion (533)) can be in contact with the conductive portion (5202) and / or the fixing member (F). Accordingly, the grounding portion of the wireless communication circuit can be electrically connected to the support plate (530) through the fixing member (F) and the conductive portion (5202).

[0089] In one embodiment, referring to FIG. 8B, a pogo pin (PO) has one end connected to a printed circuit board (510), and the other end can be inserted into the interior of the bracket (520) through a second connection hole (521) of the bracket (520) to come into contact with a portion of the support plate (530) (e.g., a second connecting portion (533)). Accordingly, a ground portion of the wireless communication circuit can be electrically connected to the support plate (530) through the pogo pin (PO).

[0090] In one embodiment, referring to FIG. 8c, the printed circuit board (510) can be directly connected to the support plate (530) via a pogo pin (PO). Accordingly, the grounding portion of the wireless communication circuit can be electrically connected to the support plate (530) via the pogo pin (PO).

[0091] According to one embodiment, as illustrated in FIGS. 8A, 8B, 8C, and 8D, the support plate (530) may be an antenna radiator that is electrically connected to a wireless communication circuit of a printed circuit board (510) and operates as an antenna in a predetermined resonant frequency band. In one embodiment, a feeding unit of the wireless communication circuit may be electrically connected to the support plate (530) and transmit a feeding signal. For example, the support plate (530) may be electrically connected to the feeding unit of the wireless communication circuit by being connected to the printed circuit board (510) through a fixing member (F) and / or a pogo pin (PO), and may thus operate as an antenna radiator in a predetermined resonant frequency band. In one embodiment, the resonant frequency band may vary depending on the shape and / or length of the support plate (530).

[0092] According to one embodiment, as illustrated in FIGS. 8A, 8B, 8C, and 8D, the support plate (530) can adjust various types of antenna resonance frequency bands used for communication of the wearable electronic device (101, 200, 400). For example, the support plate (530) can be electrically connected to a wireless communication circuit by being connected to the printed circuit board (510) through a fixing member (F) and / or a pogo pin (PO). The wearable electronic device (101, 200, 400) can include a switching circuit (not shown) disposed in an electrical path connecting the support plate (530) and the printed circuit board (510). The switching circuit can include at least one switch and / or passive elements having different element values ​​that are connected to or disconnected from the electrical path by the at least one switch. The passive components may include capacitors with various capacitance values ​​and / or inductors with various inductance values. Accordingly, the wireless communication circuit can vary the resonant frequency band by changing the length of the antenna through a switching circuit.

[0093] According to one embodiment, as illustrated in FIG. 8d, the support plate (530) can be electrically connected to the printed circuit board (510) via at least two fixing members (F) or pogo pins (PO). For example, one of the plurality of fixing members (F) (or pogo pins (PO)) can electrically connect the first coupling portion (532) of the support plate (530) and the printed circuit board (510). The other of the plurality of fixing members (F) (or pogo pins (PO)) can electrically connect the second coupling portion (533) of the support plate (530) and the printed circuit board (510). In one embodiment, the ground of the wireless communication circuit can be connected to the support plate (530) via one of the plurality of fixing members (F) (or pogo pins (PO)). The support plate (530) can be connected to the power supply of the wireless communication circuit through the remaining one of the plurality of fixing members (F) (or pogo pins (PO)) and can be operated as an antenna radiator in a certain known frequency band.

[0094] In one embodiment, referring to FIG. 8E, the support plate (530) may be formed to surround the battery (540) on the front (e.g., the side facing the +Z direction in FIG. 8E), the back (e.g., the side facing the -Z direction in FIG. 8E), and the side surrounding the space between the front and back. For example, the battery plate (530) may include a cover portion (534) facing the support portion (531) in the support plate (530) illustrated in FIG. 7 and connected to the coupling portions (532, 533). In this case, the battery (530) may be disposed in the internal space of the support plate (530) formed by surrounding the support portion (531), the coupling portions (532, 533), and the cover portion (534) of the support plate (530).
