Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal equipment, and in particular to a wearable device. BACKGROUND

[0002] With the continuous progress of science and technology, wearable devices such as smart watches and smart bands are increasingly favored by people due to their powerful functions and convenient operation. Wearable devices not only have the function of displaying time like traditional watches, but also have functions such as surfing the Internet, making calls, taking photos, sending and receiving emails, measuring heart rate, and measuring blood oxygen.

[0003] The wearable device includes a device body and a band connected to the device body, and the band is used to wear the device body on the body of a user. The device body is equipped with a screen assembly, a circuit board, a battery, a speaker, a microphone, a key, and a biological sensor, and the like. The circuit board is located between the screen assembly and the battery, the biological sensor is located on the circuit board, and the speaker (SPK), the microphone (MIC), and the key are arranged around the battery.

[0004] Since each device has a certain size, the above-mentioned device layout mode can cause the thickness of the whole machine to increase, and the space occupied by the multiple devices around the battery is large, which affects the layout space of the battery, reduces the size of the battery, and further affects the capacity of the battery, resulting in low endurance. It can be seen that the existing wearable device has the problem of unreasonable device layout, which leads to low space utilization. SUMMARY

[0005] The present application provides a wearable device to solve the problem of unreasonable device layout of the existing wearable device, which leads to low space utilization.

[0006] The present application provides a wearable device, which includes a screen assembly, a battery assembly, and a mainboard assembly. The screen assembly, the battery assembly, and the mainboard assembly are sequentially stacked along a first direction, and the first direction is the thickness direction of the wearable device; the screen assembly and the battery assembly have a first gap, and the first gap is configured to provide space for the battery assembly and avoid the screen assembly; and the mainboard assembly is attached to the battery assembly.

[0007] The wearable device provided by the embodiments of the present application adopts a layout mode in which the screen assembly, the battery assembly and the mainboard assembly are stacked in sequence, and more thickness space can be obtained on the thickness of the whole machine. With the obtained thickness space, the thickness of the whole machine can be reduced under the condition that the capacity of the battery assembly remains unchanged, the thickness size of the battery assembly can be increased under the condition that the thickness of the whole machine remains unchanged, and the thickness of the whole machine can be reduced and the thickness size of the battery assembly can be increased simultaneously with the remaining part of the obtained thickness space. Therefore, the device layout mode of the whole machine architecture adopted by the embodiments of the present application is reasonable, the space utilization rate is high, and the greater battery capacity can be obtained while the thickness of the whole machine is thin, so as to realize the user experience of thin appearance and long battery life.

[0008] In some implementations, further comprising: a middle frame assembly, a subboard assembly and a back cover assembly; along the first direction, the screen assembly and the back cover assembly are located on opposite sides of the middle frame assembly to form an accommodation cavity; the battery assembly, the mainboard assembly and the subboard assembly are located in the accommodation cavity, the subboard assembly is located between the mainboard assembly and the back cover assembly, and the subboard assembly is electrically connected with the mainboard assembly. In this way, a reasonable device layout mode can be adopted to improve the space utilization rate.

[0009] In some implementations, further comprising: a key assembly and a loudspeaker; the key assembly is located on the middle frame assembly, and the loudspeaker is located in the accommodation cavity; the loudspeaker and the key assembly are located on the same side of the battery assembly along a second direction, and the second direction is the width direction of the wearable device. In this way, the device with a larger width size is arranged on the same side of the battery assembly, the space occupied by each device in the width direction can be reduced, and the width of the battery assembly can be increased to increase the capacity of the battery assembly.

[0010] In some implementations, the first gap is less than or equal to 0.45 mm. In this way, the gap between the screen assembly and the battery assembly is reduced, and more thickness space can be obtained on the thickness of the whole machine.

[0011] In some implementations, the back cover assembly comprises a protruding portion and an annular portion; the protruding portion is opposite to the mainboard assembly, and the protruding portion protrudes away from the mainboard assembly along the first direction; and the annular portion is connected to the outer side of the protruding portion and is connected to the middle frame assembly in a smooth transition. In this way, the curvature of the back cover assembly can be made more rounded, and the appearance effect is good.

[0012] In some implementations, further comprising: a plurality of first devices; and the plurality of first devices are located on the surface of the mainboard assembly away from the battery assembly. In this way, all the first devices are arranged on one surface of the mainboard assembly, and more thickness space can be obtained on the thickness of the whole machine.

[0013] In some implementations, the first device includes a target device, which refers to a device with a device height greater than or equal to a first threshold value; the target device is located in a region of the mainboard assembly opposite the protrusion. In this way, the protrusion can accommodate part of the height of the target device, without increasing the overall thickness of the device, thereby allowing more thickness space to be obtained in the overall thickness.

[0014] In some implementations, the subboard assembly is located in the cavity space formed by the protrusion, so that the device height of the second device on the subboard assembly is not in the thickness dimension chain of the overall thickness, and the device height of the second device does not increase the overall thickness. The second gap is provided between the subboard assembly and the target device, so that interference between the target device and the subboard assembly can be avoided.

[0015] In some implementations, the battery assembly includes connected battery cells and a battery protection plate; the battery protection plate is located between the battery cells and the middle frame assembly, and a first distance is provided between the battery protection plate and the screen assembly, the first distance being greater than the first gap, so that the battery cells, the battery protection plate, the middle frame assembly and the screen assembly enclose a first region; and the screen assembly includes screen devices; the screen devices are located on a surface of the screen assembly facing the battery assembly and in the first region. In this way, the region of the screen assembly opposite the battery cells is no longer provided with screen devices, and the first region is used to accommodate the screen devices, so that the space of the screen devices in the overall thickness direction of the accommodation cavity can be avoided.

[0016] In some implementations, the screen devices and the battery protection plate are staggered in a third direction, which is the length direction of the wearable device. In this way, interference between the battery cells and the screen devices can be avoided.

[0017] In some implementations, the screen assembly further includes a near field communication (NFC) module and a screen flexible printed circuit (FPC); along the third direction, the NFC module and the screen FPC are staggered in the part located in the projection area of the battery cells; the main part of the NFC module and the main part of the screen FPC are located in the region of the screen assembly opposite the battery cells, and the remaining part of the NFC module and the remaining part of the screen FPC extend beyond the region of the screen assembly opposite the battery cells, and the screen devices are located on the remaining part of the screen FPC. In this way, the NFC module and the screen FPC are staggered in the same plane, which can further obtain more thickness space in the overall thickness.

[0018] In some implementations, further including: a motor; the motor is located in the accommodation cavity, and the motor, the key assembly and the speaker are located on the same side of the battery assembly along the second direction, and the key assembly is located between the motor and the speaker. In this way, the space occupied by each device in the width direction and the length direction can be reduced at the same time, and the space is used to increase the width and the length of the battery assembly to increase the capacity of the battery assembly.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] In the description of the present application, the terms "first", "second", and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0034] In addition, in the present application, the orientation terms such as "upper", "lower", "left", "right", and the like are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0035] Figure 1 It is a structural schematic diagram of a smart watch.

[0036] As Figure 1As shown, the smart watch includes a screen 10, a back cover (not shown in the figure), a middle frame 30 and a watchband assembly 40. The screen 10 and the back cover are located on opposite sides of the middle frame 30 along the z-axis direction and are connected to enclose a whole machine cavity.

[0037] To facilitate the description of the positions of various components in the smart watch, the embodiments of the present application exemplarily establish a three-dimensional coordinate system based on the smart watch, wherein the x-axis direction is the width direction of the smart watch, the y-axis direction is the length direction of the smart watch, and the z-axis direction is the thickness direction of the smart watch.

[0038] The middle frame 30 is substantially in the shape of a rectangular frame, and the four corners of the rectangle can be processed by chamfering to be circularly arc-shaped to make the wearable device have better appearance characteristics. In other embodiments, the middle frame 30 can also be in the shape of a circular frame. The side surface of the middle frame 30 can be provided with a watchband buckle for mounting the watchband assembly 40, and the watchband assembly 40 can form reliable connection with the middle frame 30 through the watchband buckle on the middle frame 30. Specifically, the watchband assembly 40 is fixed to opposite ends of the middle frame 30 along the y-axis direction, so as to facilitate wearing the smart watch on any position of the user as needed, including but not limited to limbs or trunk.

[0039] Figure 2 is a schematic view of a cross-sectional structure of a smart watch. Among them, Figure 2 shows the cross-sectional structure along the y-axis direction.

[0040] As Figure 2 shown, the watchband buckle 31 is two, and the watchband assembly 40 includes two watchbands, and the two watchband buckles 31 are located at opposite ends of the middle frame 30 along the y-axis direction to correspondingly connect the two watchbands. The watchband assembly 40 is detachably connected with the watchband buckle 31, so as to conveniently detach the watchband assembly 40 from the middle frame 30, and enable the user to conveniently replace the watchband assembly 40.

[0041] The screen 10 includes a cover plate 11, a screen module 12, a screen flexible printed circuit (FPC) 13, a screen integrated circuit chip (IC) 14 and a near field communication module (not shown in the figure) stacked in sequence along the z-axis direction. The cover plate 11 can be made of transparent materials such as glass; the screen module 12 can be a display panel; the screen IC 14 is electrically connected to part of the surface of the screen flexible printed circuit 13 and extends into the whole machine cavity; and the near field communication module is used to realize wireless communication between the smart watch and an external terminal.

[0042] The whole machine cavity includes a main board 51, a sub-board 52 and a battery 53. The main board 51 is located on one side of the screen 10, and the screen IC 14 is located in the projection area of the main board 51 along the z-axis.

[0043] The main board 51 is integrated with multiple devices to enable the smart watch to realize different functions. However, since the main board 51 is adjacent to the screen 10, the screen IC 14 on the screen 10 covers the surface area of the main board 51 facing the screen 10, and the main board 51 needs to avoid the screen IC 14 when arranging the devices to avoid damaging the screen IC 14. For example, the screen IC 14 covers the right upper surface of the main board 51, and only devices can be arranged on the left upper surface of the main board 51. Among them, the upper surface refers to the surface of the main board 51 facing the screen 10.

[0044] However, the number of devices is large, and only the first group of devices 511 can be arranged on the left upper surface of the main board 51, and the remaining second group of devices 512 need to be arranged on the surface of the main board 51 away from the screen 10. In this way, devices are arranged on the two opposite surfaces of the main board 51 to ensure that all devices can be integrated on the main board 51.

[0045] Along the z-axis direction, the first group of devices 511 and the screen 10 have an avoidance gap L1', specifically, the first group of devices 511 and the screen flexible circuit board 13 have an avoidance gap L1' to avoid interference between the first group of devices 511 and the screen flexible circuit board 13, and further to avoid mutual damage. For example, the avoidance gap L1' is 0.3mm.

[0046] The battery 53 is located on the side of the main board 51 away from the screen 10; along the z-axis direction, the battery 53 has an expansion gap L2' between the main board 51, specifically, the battery 53 and the second group of devices 512 have an expansion gap L2' to accommodate the expansion deformation of the battery 53 when running, avoid interference between the battery 53 and the second group of devices 512, and further avoid mutual damage. For example, the expansion gap L2' is 0.35mm.

[0047] The sub-board 52 is located on the side of the battery 53 away from the main board 51, and the sub-board 52 is close to the rear shell 20. The sub-board 52 is spaced apart from the main board 51, and the sub-board 52 can be electrically connected to the main board 51 through the FPC 522, so that the devices integrated on the sub-board 52 and the devices integrated on the main board 51 realize data transmission.

[0048] The sub-board 52 is integrated with multiple biological sensors 521, and the multiple biological sensors 521 are located on the surface of the sub-board 52 away from the battery 53 and extend towards the rear shell 20. The biological sensors 521 can be used to detect physiological index data, such as heart rate, respiratory rate, blood pressure, or body fat, etc. In addition, the biological sensors can also be used to detect the motion state, such as for counting steps.

[0049] The rear shell 20 comprises a convex region 21 which protrudes away from the sub-plate 52 relative to the rear shell body, and which is used to fit against the skin. The biosensor 521 corresponds to the convex region 21, so that the biosensor 521 can detect physiological index data close to the skin.

[0050] Since the convex region 21 is close to the skin, the overall thickness of the smart watch is calculated as the height between the screen 10 and the non-convex region 21 of the rear shell 20, i.e. the overall thickness H0' of the smart watch is the height between the cover plate 11 and the rear shell body.

[0051] As can be seen, each device on the main board 51 is located within the calculation range of the overall thickness H0', and the complete height of the highest device needs to be calculated in the thickness dimension chain of the overall thickness H0. For example, if the height of the highest device is 1.2 mm, then the height of the device in the thickness dimension chain is 1.2 mm. Moreover, the main board 51 uses double-sided devices, and the double-layer devices will further increase the total height of the device, thereby increasing the overall thickness H0'.

[0052] In addition, the avoidance gap L1' between the screen 10 and the main board 51, and the expansion gap L2' of the battery 53 cannot be shared, and the avoidance gap L1' and the expansion gap L2' occupy a thickness space of 0.65 mm in the overall cavity; and the near-field communication module and the screen flexible circuit board 13 are arranged in overlap, which will increase the thickness space occupied in the overall cavity. Therefore, the overall architecture layout of the smart watch will further increase the overall thickness H0'.

[0053] Figure 3 is a schematic diagram of the internal structure of a smart watch.

[0054] As shown in Figure 3 , the middle frame 30 comprises a key 57 which protrudes from the appearance surface of the middle frame 30, so as to be operated by the user.

[0055] The overall cavity of the smart watch further comprises a speaker module 54, a microphone module 55 and a motor module 56. The battery 53 is located in the middle region of the overall cavity, and the speaker module 54, the microphone module 55, the motor module 56 and the key 57 are arranged around the battery 53. The speaker module 54 is located on the left side of the battery 53, the microphone module 55 and the key 57 are located on the right side of the battery 53, and the motor module 56 is located on the lower side of the battery 53.

[0056] The various devices have different sizes, wherein the sizes of the speaker module 54, the key 57 and the motor module 56 are greater than the sizes of other devices. The speaker module 54 and the key 57 are located on the left and right sides of the battery 53, so that the speaker module 54 and the key 57 occupy the space in the width direction, and the motor module 56 occupies the space in the length direction, thereby reducing the size of the space for placing the battery 53 in the whole machine cavity. In this way, only a small size battery 53 can be placed in a small space, and the capacity of the small size battery 53 is small, thereby reducing the endurance of the smart watch.

[0057] As can be seen from the above, the layout mode of the various devices in the existing smart watch not only increases the thickness of the whole machine, but also cannot set a large capacity battery. It can be seen that the whole machine architecture of the smart watch has an unreasonable device layout, resulting in low space utilization.

[0058] To solve the above technical problems, the embodiment of the present application provides a wearable device, which can improve the space utilization to realize the user experience of light and thin appearance and long endurance.

[0059] The wearable device described in the embodiment of the present application can be a watch, a smart watch, a bracelet, a smart bracelet, glasses, an AR helmet or a VR helmet, an electronic monitoring and detection device and the like wearable products. The following describes the wearable device as a smart watch.

[0060] Figure 4 is the first structural schematic diagram of the wearable device provided by the embodiment of the present application; Figure 5 is the second structural schematic diagram of the wearable device provided by the embodiment of the present application.

[0061] As shown in Figure 4 and Figure 5 In some embodiments, the wearable device can include a screen assembly 100, a middle frame assembly 400, a back shell assembly 600 and a band assembly 900.

[0062] The screen assembly 100 and the back shell assembly 600 are located on opposite sides of the middle frame assembly 400 and are connected to form an accommodation cavity.

[0063] For the convenience of explaining the positions of various components in the wearable device, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the wearable device, wherein the x-axis direction is the width direction of the wearable device, the y-axis direction is the length direction of the wearable device, and the z-axis direction is the thickness (or height) direction of the wearable device.

[0064] The screen assembly 100 can be used to display information and provide an interactive interface for the user. The screen assembly 100 can be a touch screen to facilitate user operation.

[0065] The appearance of the middle frame assembly 400 depends on the functions that the wearable device can implement. The more functions that the wearable device can implement, the more devices that the accommodating cavity can accommodate, and the larger the appearance size of the middle frame assembly 400. The layout of the devices determines the appearance shape of the wearable device.

[0066] For example, when the wearable device can implement more functions, the accommodating cavity has a large volume to accommodate a plurality of devices. In this case, the middle frame assembly 400 can be a square frame shape, the wearable device has a square appearance, and the appearance size is large. The four corners of the square can be processed into a circular arc transition through a chamfering process, so that the wearable device has better appearance characteristics. While ensuring that the wearable device has a large volume accommodating cavity, the middle frame assembly 400 can also be a circular frame shape.

[0067] Along the y-axis direction, the two side surfaces of the middle frame assembly 400 can be provided with a matching structure 401 for mounting the strap assembly 900. The strap assembly 900 can be reliably connected to the middle frame assembly 400 through the matching structure 401 on the middle frame assembly 400. Specifically, the strap assembly 900 is fixed to the opposite ends of the middle frame assembly 400 along the y-axis direction, so as to facilitate wearing the wearable device on any position of the user that needs to be fixed, including but not limited to limbs or the torso.

[0068] For example, the matching structure 401 is two, and the strap assembly 900 includes two watchbands. The two matching structures 401 are located at the opposite ends of the middle frame assembly 400 along the y-axis direction, so as to one-to-one correspondingly connect the two watchbands. The strap assembly 900 is detachably connected to the matching structure 401, so as to facilitate detaching the strap assembly 900 from the middle frame assembly 400, and enable the user to conveniently replace the strap assembly 900.

[0069] Figure 6 is Figure 4 A first structure diagram of the cross section A-A.

[0070] As Figure 6 shown, in some embodiments, the wearable device can include a battery assembly 200 and a mainboard assembly 300, and the battery assembly 200 and the mainboard assembly 300 are located in the accommodating cavity. The screen assembly 100, the battery assembly 200, and the mainboard assembly 300 are sequentially stacked along a first direction, and the first direction is the thickness direction (z-axis direction) of the wearable device.

[0071] The back shell assembly 600 is located on the side of the mainboard assembly 300 away from the screen assembly 100. The back shell assembly 600 can include a protruding portion 601 and an annular portion 602. The protruding portion 601 is opposite to the mainboard assembly 300, and the protruding portion 601 protrudes in a direction away from the mainboard assembly 300 along the first direction. The annular portion 602 is connected to the outer side of the protruding portion 601, and the annular portion 602 is connected to the middle frame assembly 400.

[0072] The protrusion 601 is used to fit the skin closely, and the overall thickness of the wearable device is calculated in the height between the screen assembly 100 and the non-protrusion 601 of the rear shell assembly 600, that is, the overall thickness H0 of the wearable device is the height between the screen assembly 100 and the ring-shaped portion 602.

[0073] The accommodation cavity needs to reserve a screen assembly 100 avoidance gap to avoid interference between the screen assembly 100 and other devices in the accommodation cavity, thereby avoiding mutual damage; and needs to reserve a battery assembly 200 expansion gap to avoid interference between the expanded battery assembly 200 and other devices in the accommodation cavity, thereby avoiding mutual damage.

[0074] The battery assembly 200 is close to the screen assembly 100, and the screen assembly 100 and the battery assembly 200 have a first gap L1 therebetween. Exemplarily, the first gap L1 is less than or equal to 0.45 mm.

[0075] On the overall thickness H0, the avoidance gap of the screen assembly 100 and the expansion gap of the battery assembly 200 are adjacent, and the two gaps can be overlapped and shared, that is, the first gap L1 can provide expansion space for the battery assembly 200 and also avoid the screen assembly 100. In this way, compared with the scheme in which the avoidance gap L1' and the expansion gap L2' are separated and not shared (see again Figure 2 ), the embodiment of the present application can benefit from a thickness space of at least 0.2 mm on the overall thickness H0.

[0076] The mainboard assembly 300 is adjacent to the rear shell assembly 600, and the mainboard assembly 300 can be fixed on the middle frame assembly 400. The mainboard assembly 300 is attached to the battery assembly 200, and the battery assembly 200 can be attached to the surface of the mainboard assembly 300 facing the screen assembly 100 by an adhesive (not shown in the figure). Compared with the scheme in which the battery and the mainboard are separately arranged, the battery assembly 200 attached to the surface of the mainboard assembly 300 can further benefit from a thickness space on the overall thickness H0.

[0077] The wearable device provided by the embodiments of the present application adopts the layout mode of stacking the screen assembly 100, the battery assembly 200 and the mainboard assembly 300 in the z direction from top to bottom, can utilize the first gap L1 between the screen assembly 100 and the battery assembly 200 to jointly provide the expansion space for the battery assembly 200, and avoid the screen assembly 100 to obtain a thickness space of at least 0.2 mm on the whole machine thickness H0. Meanwhile, the battery assembly 200 and the mainboard assembly 300 are arranged in close contact, which can further obtain a thickness space on the whole machine thickness H0. In this way, the thickness space can be utilized to reduce the whole machine thickness H0 under the condition that the capacity of the battery assembly 200 remains unchanged; the thickness space can also be utilized to increase the thickness size of the battery assembly 200 under the condition that the whole machine thickness H0 remains unchanged, thereby increasing the capacity of the battery assembly 200; and part of the thickness space can be utilized to reduce the whole machine thickness H0, and the remaining part of the thickness space can be utilized to increase the thickness size of the battery assembly 200. Therefore, the device layout mode of the whole machine architecture provided by the embodiments of the present application is reasonable, the space utilization rate is high, the greater battery capacity can be obtained while the whole machine thickness is thin, and the user experience of light and thin appearance and long endurance can be realized.

[0078] In some embodiments, referring again to Figure 2 , in the prior scheme, the rear shell 20 is adjacent to the battery 53, and when designing the appearance of the rear shell 20, the shape of the battery 53 needs to be considered to avoid the battery 53. In this way, the connection position of the rear shell 20 and the middle frame 30 presents an edge, that is, there is a problem of too square arc of the rear shell 20, and the appearance effect is not good.

[0079] The battery assembly 200 provided by the embodiments of the present application is far away from the rear shell assembly 600, and when designing the appearance of the rear shell assembly 600, the size of the battery assembly 200 does not need to be considered, so that the annular part 602 of the rear shell assembly 600 and the middle frame assembly 400 can be connected in smooth transition. In this way, the arc of the rear shell assembly 600 is more round, and the appearance effect is good.

[0080] In some embodiments, referring again to Figure 6 , the battery assembly 200 can include the battery cell 201 and the battery protection plate 202 connected to each other, the battery protection plate 202 is connected to the third direction side surface of the battery cell 201, the battery protection plate 202 extends along the third direction, and the third direction is the length direction (y-axis direction) of the wearable device. The battery cell 201 and the battery protection plate 202 are both located between the screen assembly 100 and the mainboard assembly 300, and the battery protection plate 202 is located between the battery cell 201 and the middle frame assembly 400.

[0081] The thickness of the battery protection plate 202 is less than the thickness of the battery cell 201, and the battery protection plate 202 is located at the middle of the axial total height of the battery cell 201, that is, the upper surface of the battery protection plate 202 is lower than the upper surface of the battery cell 201. The upper surface refers to the surface of the device facing the screen assembly 100, and the position relationship of "lower" is based on the state shown in the figure. Figure 6

[0082] In this way, the battery protection plate 202 has a first distance D1 from the screen assembly 100, and the first distance D1 is greater than the first gap L1, so that the battery cell 201, the battery protection plate 202, the middle frame assembly 400 and the screen assembly 100 form a first area (not shown in the figure).

[0083] The screen assembly 100 can include screen devices 101. For example, the screen devices 101 can include screen IC, capacitor, inductor and the like.

[0084] To avoid interference between the battery cell 201 and the screen devices 101, the screen devices 101 are located on the surface of the screen assembly 100 facing the battery assembly 200, and are located in the first area. The screen devices 101 protrude into the first area relative to the lower surface of the screen assembly 100, wherein the lower surface refers to the surface of the screen assembly 100 facing the battery assembly 200.

[0085] The screen devices 101 and the battery protection plate 202 are staggered in the third direction, that is, the screen devices 101 and the battery protection plate 202 have an overlapping area in the y-axis direction, so that the screen devices 101 and the battery cell 201 do not have an overlapping area in the y-axis direction, and do not have an overlapping area in the z-axis direction, avoiding the screen devices 101 from blocking the battery cell 201. At the same time, the battery protection plate 202 and the screen devices 101 have a gap in the z-axis direction to prevent impact.

[0086] In the embodiment of the present application, the first area between the screen assembly 100 and the battery protection plate 202 is used to accommodate the screen devices 101, and the area of the screen assembly 100 opposite to the battery cell 201 is not provided with screen devices 101, which can avoid the screen devices 101 occupying the space of the accommodating cavity in the thickness H0 direction of the whole machine.

[0087] Figure 7 FIG. 1 is a structural schematic diagram of a mainboard assembly, a subboard assembly and a rear shell assembly provided by the embodiment of the present application. Among them, Figure 7 only part of the structure in Figure 6 is shown.

[0088] combined with Figure 6 and Figure 7 ​As shown, in some embodiments, the wearable device can further include a plurality of first devices 801, which are located in the accommodating cavity and on the surface of the mainboard assembly 300 away from the battery assembly 200. Different first devices 801 can implement different functions. For example, the first devices 801 can include a main chip, a proximity sensor, a touch sensor, a force sensor, a vibration sensor, an orientation sensor, a motion sensor (e.g., an accelerometer or a speed sensor), a position sensor (e.g., a global positioning system GPS device), a thermal sensor, a resistance sensor, or a magnetic sensor, etc.

[0089] Based on the overall architecture layout of the wearable device provided in the embodiments of the present application, the screen device 101 is located outside the projection area of the battery cell 201, and the screen device 101 is separated from the mainboard assembly 300 by a distance, so that the screen device 101 does not hinder the layout positions of the devices on the mainboard assembly 300. Therefore, all the first devices 801 can be arranged on the same surface of the mainboard assembly 300.

[0090] In this way, compared with the scheme of double-sided layout of devices adopted in the prior art, the embodiments of the present application arrange the first devices 801 on only one surface of the mainboard assembly 300, which can reduce the height of one layer of devices, and thus can save a thickness space of at least 0.9 mm on the overall thickness H0 of the wearable device.

[0091] In some embodiments, the device heights of different first devices 801 are different. The first devices 801 can include target devices 8011 and other devices 8012. The target devices 8011 refer to devices with a device height greater than or equal to a first threshold value, and the other devices 8012 refer to devices with a device height less than the first threshold value. For example, the first threshold value can be 0.8 mm.

[0092] Each first device 801 extends in the direction from the lower surface of the mainboard assembly 300 to the rear shell assembly 600, and the distance between the mainboard assembly 300 and the protruding part 601 of the rear shell assembly 600 is greater than the distance between the mainboard assembly 300 and the annular part 602. The lower surface refers to the surface of the mainboard assembly 300 facing the rear shell assembly 600. The target devices 8011 are located in the area of the mainboard assembly 300 opposite to the protruding part 601, and the other devices 8012 are located around the target devices 8011, i.e., in the area of the mainboard assembly 300 opposite to the annular part 602.

[0093] The other device 8012 with a low device height is arranged in the area of the mainboard assembly 300 opposite the annular portion 602, and the device height of the other device 8012 is less than 0.8 mm. Therefore, the distance between the mainboard assembly 300 and the annular portion 602 is greater than or equal to 0.8 mm. Thus, only the device height of 0.8 mm needs to be calculated in the thickness dimension chain of the overall thickness H0.

[0094] The target device 8011 with a high device height is arranged in the area of the mainboard assembly 300 opposite the protruding portion 601, and the protruding portion 601 accommodates part of the height of the target device 8011. Since the protruding portion 601 is not in the thickness dimension chain of the overall thickness H0, the complete height of the target device 8011 does not need to be calculated in the thickness dimension chain of the overall thickness H0, and only part of the height of the target device 8011 needs to be calculated.

[0095] For example, when the height of the target device 8011 is 1.2 mm, the device height of the target device 8011 that needs to be calculated in the thickness dimension chain is 0.8 mm, and the device height that does not need to be calculated in the thickness dimension chain is 0.4 mm.

[0096] Therefore, the target device 8011 with a high device height is arranged in the area of the mainboard assembly 300 opposite the protruding portion 601, and the overall thickness H0 does not increase, and at least 0.4 mm of thickness space can be obtained on the overall thickness H0.

[0097] It should be noted that when the number of target devices 8011 is small, the other device 8012 can also be arranged in the area of the mainboard assembly 300 opposite the protruding portion 601. In addition, Figure 7 All the target devices 8011 and the other device 8012 are not shown in the figures to make the figures clear.

[0098] Again referring to the content shown in Figure 6 and Figure 7 In some embodiments, the wearable device can further include a secondary board assembly 500 located in the accommodation cavity. The secondary board assembly 500 is located between the mainboard assembly 300 and the rear shell assembly 600, and the secondary board assembly 500 is mounted on the rear shell assembly 600. The mainboard assembly 300 and the secondary board assembly 500 can be electrically connected through an FPC or a connector (not shown in the figures).

[0099] The secondary board assembly 500 and the target device 8011 have a second gap L2 to avoid interference between the target device 8011 and the secondary board assembly 500.

[0100] The plurality of second devices 802 are integrated on the sub-board assembly 500, each of the second devices 802 is located on a surface of the sub-board assembly 500 facing the back shell assembly 600 and extends towards the back shell assembly 600. The second devices 802 can be a photoplethysmography (PPG) optical detection module for detecting physiological index data such as heart rate, respiration rate, blood oxygen, blood pressure, or body fat, etc.

[0101] In order to facilitate the second devices 802 to accurately detect the physiological index data of the user, the second devices 802 need to be close to the back shell assembly 600 due to the convex portion 601 of the back shell assembly 600 abutting the skin of the user. Therefore, the sub-board assembly 500 can be located in the cavity space formed by the convex portion 601. Moreover, in order to avoid the target device 8011, the sub-board assembly 500 can be further lowered to a position closer to the convex portion 601.

[0102] In this way, the second devices 802 are located in the cavity space formed by the convex portion 601, so that the device height of the second devices 802 is not in the thickness dimension chain of the overall thickness H0, and the device height of the second devices 802 will not cause the increase of the overall thickness H0. By using the cavity space formed by the convex portion 601 to accommodate the entire height of the second devices 802 and the partial height of the first device 801, more thickness space can be further obtained on the overall thickness H0.

[0103] Figure 8 FIG. 1 is a structural schematic diagram of a screen assembly provided by an embodiment of the present application.

[0104] In combination with Figure 6 and Figure 8 As shown in FIG. 1, in some embodiments, the screen assembly 100 can further include a near field communication (NFC) module 102, a screen flexible printed circuit board (FPC) 103, a screen cover plate 104, and a display panel 105. The NFC module 102 is configured to realize wireless communication between the wearable device and an external terminal; the screen FPC 103 is configured to realize electrical connection of devices in the screen assembly 100; the screen cover plate 104 can be made of transparent materials such as glass, and is used to protect the display panel 105; and the display panel 105 is configured to present a user interface.

[0105] In the direction of the z-axis, the screen cover plate 104 and the display panel 105 are stacked in sequence, and the NFC module 102 and the screen FPC 103 are located on a surface of the display panel 105 facing the battery assembly 200.

[0106] In the y-axis direction, the NFC module 102 and the screen FPC 103 are arranged in a staggered manner in the part located in the projection area of the battery cell 201, and / or in the x-axis direction, the NFC module 102 and the screen FPC 103 are arranged in a staggered manner in the part located in the projection area of the battery cell 201. The projection area of the battery cell 201 refers to the projection of the battery cell 201 in the z-axis direction towards the screen assembly 100. There is no overlapping area between the NFC module 102 and the screen FPC 103 in the z-axis direction, so that in the thickness dimension chain of the whole machine thickness H0, only the height of the device with the maximum height among the NFC module 102 and the screen FPC 103 needs to be calculated, and the heights of the NFC module 102 and the screen FPC 103 do not need to be calculated at the same time.

[0107] For example, if the height of the NFC module 102 and the height of the screen FPC 103 are both 0.1 mm, the height of the device in the thickness dimension chain of the whole machine thickness H0 is 0.1 mm; if the height of the NFC module 102 is 0.1 mm and the height of the screen FPC 103 is 0.2 mm, the height of the device in the thickness dimension chain of the whole machine thickness H0 (the height of the screen FPC 103) is 0.2 mm.

[0108] In this way, compared with the scheme in which the NFC module 102 and the screen FPC 103 are arranged in an overlapping manner in the prior art, the NFC module 102 and the screen FPC 103 are arranged in a staggered manner on the same plane in the embodiment of the present application, and more thickness space can be obtained on the whole machine thickness H0.

[0109] Figure 8 The B1 area shown by the dotted line in the middle is the projection area of the battery cell 201 in the z-axis direction on the screen assembly 100. The main part of the NFC module 102 and the main part of the screen FPC 103 are located in the area B1 of the screen assembly 100 opposite to the battery cell 201. The connecting part of the NFC module 102 and the connecting part of the screen FPC 103 extend beyond the area B1 of the screen assembly 100 opposite to the battery cell 201. The screen device 101 is located on the connecting part of the screen FPC 103. In the drawings, the structures of the main part and the connecting part are not shown.

[0110] In the embodiment of the present application, other devices (such as the screen device 101, the connector, etc.) in the screen assembly 100 are arranged outside the projection area B1 of the battery cell 201, so as to avoid the relative position of the other devices and the battery cell 201. In this way, it is not necessary to reserve a certain avoiding space between the devices and the battery cell 201, and the complete device height of the corresponding device does not need to be calculated in the thickness dimension chain of the whole machine thickness H0, so as to avoid increasing the whole machine thickness H0, and further obtain more thickness space on the whole machine thickness H0.

[0111] Figure 9is a first top view of the wearable device provided by an embodiment of the present application. In the figure, Figure 9 The structure of the screen assembly 100 and the strap assembly 900 is not shown in the middle.

[0112] As shown in Figure 9 some embodiments, the mainboard assembly 300 and the middle frame assembly 400 can be fixed by screws 402, which can be distributed at the four corners of the mainboard assembly 300 to improve reliability.

[0113] In some embodiments, the wearable device can further include a key assembly 701, a speaker 702, a motor 703, and a microphone 704. The key assembly 701 is located on the middle frame assembly 400, and the speaker 702, the motor 703, and the microphone 704 are all located in the accommodation cavity of the wearable device.

[0114] The key assembly 701 can be located on the right side of the battery assembly 200 and on the right side frame of the middle frame assembly 400. The key assembly 701 is configured to perform pressing or rotating operations to perform different operations. The key assembly 701 can include a rotary knob 7011 and a key body 7012 connected to each other, the key body 7012 being located in the accommodation cavity, and the rotary knob 7011 being exposed on the appearance surface of the middle frame assembly 400.

[0115] The speaker 702 and the key assembly 701 are located on the same side of the battery assembly 200 along a second direction, which is the width (x-axis) direction of the wearable device, that is, the speaker 702 and the key assembly 701 are both located on the right side of the battery assembly 200.

[0116] The motor 703 is arranged on the upper side of the battery assembly 200 along a third (y-axis) direction, and the motor 703 and the battery protection plate 202 are located on opposite sides of the battery assembly 200. The motor 703 and the battery assembly 200 are in a series arrangement relationship in the length direction of the whole machine, that is, the y-axis direction.

[0117] The microphone 704 is arranged on the left side frame of the middle frame assembly 400 opposite the key assembly 701 and adjacent to the battery assembly 200.

[0118] In the x-axis direction, different devices have different widths. The width W 7012 of the key body 7012 and the width W 702 of the speaker 702 are relatively large, and the width W 704 of the microphone 704 is relatively small. Therefore, arranging devices with large width dimensions on the same side and arranging devices with small width dimensions on the opposite side can reduce the space occupied by each device in the x-axis direction of the accommodation cavity. In addition, arranging the motor 703 on the upper side of the battery assembly 200 can also reduce the space occupied in the x-axis direction of the accommodation cavity.

[0119] In this way, in the accommodating cavity, reasonable arrangement of the devices around the battery assembly 200 can reduce the space occupied in the x-axis direction, and thus the width direction benefit can be obtained. By using the width direction benefit, the width of the battery assembly 200 can be increased, so as to increase the capacity of the battery assembly 200 and avoid the poor endurance of the wearable device.

[0120] In combination with the foregoing, Figure 8 the content shown, Figure 8 The area B2 shown by the dotted line represents the projection area of the loudspeaker 702 along the z-axis direction on the screen assembly 100. The projection area B2 of the loudspeaker 702 is located outside the projection area B1 of the battery cell 201 and outside the NFC module 102, so as to avoid interference between the loudspeaker 702 and the NFC module 102 and to avoid the increase in the thickness of the whole machine due to the overlap of the two.

[0121] The wearable device provided by the embodiment of the present application places the key assembly 701 with a large width size and the loudspeaker 702 on the same side. Compared with the prior art scheme of placing the loudspeaker module 54 and the key 57 on two sides, the width of the battery assembly 200 can be increased, so as to achieve the light and thin thickness of the whole machine while obtaining a larger battery capacity and improving the endurance.

[0122] Figure 10 FIG. 2 is a second top view of the wearable device provided by the embodiment of the present application. In FIG. 2, Figure 10 The structure of the screen assembly 100 is not shown in FIG. 2.

[0123] As shown in FIG. 2, Figure 10 In some embodiments, the embodiment of the present application further provides another wearable device. Compared with the wearable devices provided by the foregoing embodiments, the difference lies in that the layout position of the motor 703 in the accommodating cavity is different.

[0124] The motor 703, the key assembly 701 and the loudspeaker 702 are located on the same side of the battery assembly 200 along the second direction. For example, the key assembly 701, the loudspeaker 702 and the motor 703 are located on the right side of the battery assembly 200. The key assembly 701 is located between the motor 703 and the loudspeaker 702, so as to obtain a better appearance effect.

[0125] The motor 703 is moved from the upper side of the battery assembly 200 to the right side of the battery assembly 200, so that the top end of the battery assembly 200 can extend to the top of the middle frame assembly 400. In this way, the corner position of the mainboard assembly 300 opposite to the end of the battery assembly 200 cannot be fixed to the middle frame assembly 400 by screws due to space limitation.

[0126] Therefore, the area of the middle frame assembly 400 opposite to the corner position includes the buckle 403, and the buckle 403 is used to fix the main plate assembly 300 to reduce the occupied space. The rest of the main plate assembly 300 is still fixed on the middle frame assembly 400 through the screw 402.

[0127] Figure 11 is Figure 4 The second structural schematic view of the middle A-A section.

[0128] In combination Figure 10 and Figure 11 As shown in FIG. 7, in some embodiments, the width of the motor 703 is large, the devices with large width size are arranged on the same side, and the devices with small width size are arranged on the opposite side, so as to reduce the space occupied by the devices in the x-axis direction of the accommodating cavity. In addition, along the y-axis direction, the side of the battery assembly 200 is no longer arranged with the motor 703, so as to reduce the space occupied by the battery assembly 200 in the y-axis direction, so as to increase the length of the battery assembly 200 by using the space, and the end of the battery assembly 200 can be close to the opposite end of the middle frame assembly 400.

[0129] In the accommodating cavity, the devices around the battery assembly 200 are reasonably arranged, so as to reduce the space occupied in the x-axis direction and the y-axis direction, and then the width direction and the length direction can be obtained. By using the benefits obtained in the width direction and the length direction, the width and the length of the battery assembly 200 can be increased, so as to increase the capacity of the battery assembly 200 and avoid the poor endurance of the wearable device.

[0130] In this way, the key assembly 701, the speaker 702 and the motor 703 with large width size are arranged on the same side, so as to increase the width and the length of the battery assembly 200 at the same time, and then the larger battery capacity can be obtained while the thickness of the whole machine is thin, and the endurance is improved.

[0131] It should be noted that the remaining structural characteristics of the wearable device can refer to the structural characteristics of the wearable device provided in the foregoing embodiments, and details are not described herein.

[0132] In some embodiments, in order to prevent the wearable device from being dived or falling, the rear shell assembly 600 is deformed to hit the sub-plate assembly 500, and the devices on the main plate assembly 300 and the sub-plate assembly 500 are damaged, it is necessary to ensure that the gap between the rear shell assembly 600 and the sub-plate assembly 500 is greater than 0.1 mm, and the thickness of the appearance structure of the rear shell assembly 600 is greater than 0.4 mm.

[0133] The various wearable devices provided by the embodiments of the present application have a reasonable layout of the overall architecture, which can realize more reasonable position setting of internal devices under specific specifications and sizes, thereby improving space utilization, providing more space to increase battery volume in the case of realizing a thinner thickness of the overall machine, and guaranteeing long endurance.

[0134] It is to be understood that even though a number of embodiments of the present application have been described above with a certain degree of particularity, the present application is by no means limited thereto, and that many modifications and variations of the embodiments described herein are possible in light of the above teachings. It is also to be understood that the present application can be put into effect not only in the methods described above, but also in other similar methods, and that in its broadest form the present application is defined by the claims appended hereto.

[0135] It is to be understood that the application is not limited to the precise details of design and construction described herein and illustrated in the drawings and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application is defined by the claims appended hereto.
