Description

Technical Field

[0001] The present application relates to the technical field of smart devices, and in particular to a wearable device. Background Art

[0002] Smart devices usually use augmented reality (AR) or virtual reality (VR) technology. In order to enable users to better experience AR and VR technology, AR and VR are usually displayed using wearable devices.

[0003] Current wearable devices tend to be lightweight and thin in design, and the legs tend to be narrower and thinner in design. Batteries, motherboards and other components need to be installed in the effective leg space. The motherboard needs to be connected to other devices such as batteries through a flexible printed circuit (FPC), and the battery provides power to the motherboard.

[0004] Among them, the flexible circuit board is usually provided with a power line, and the main board and the battery are electrically connected through the power line on the flexible circuit board. Due to the limited installation space of wearable devices, the width of the flexible circuit board in related technologies is set to be relatively narrow. In addition, the flexible circuit board is also provided with a signal line, resulting in a narrow routing width of the power line on the flexible circuit board, which cannot effectively reduce the conductive impedance of the power line, that is, it cannot effectively reduce the conductive impedance in the current loop. Summary of the invention

[0005] The embodiment of the present application provides a wearable device that can effectively reduce the conductive impedance in a current loop.

[0006] The present application provides a wearable device, including:

[0007] The wearing body is conductive;

[0008] A flexible circuit board, comprising a first circuit;

[0009] a main board including a first electrode and a second electrode; and

[0010] A battery is used to power the mainboard, the battery comprising a third electrode and a fourth electrode, the third electrode is electrically connected to the first electrode through the first line, and the fourth electrode is electrically connected to the second electrode through the wearable body.

[0011] The wearable device provided in the embodiment of the present application electrically connects the third electrode of the battery to the first electrode of the main board through the first circuit in the flexible circuit board, and electrically connects the fourth electrode of the battery to the second electrode of the main board through the conductive wearable body. In this way, the wearable body and the first circuit of the flexible circuit board can be used to realize a complete current loop between the battery and the main board, that is, the battery can power the main board. Compared with the related art that sets the entire current loop on the flexible circuit board, when the size of the flexible circuit board remains unchanged, since the wearable body is used as part of the current loop, there is more space on the flexible circuit board of the present application to set the first circuit, that is, the width of the first circuit can be made wider, which effectively reduces the conductive impedance in the current loop. In other words, when the conductive impedance remains unchanged, the flexible circuit board of the present application can be set smaller, which is more conducive to the miniaturization design of the wearable device. In addition, it can also be understood that the wearable body is used as part of the current loop. Generally speaking, the size of the wearable body itself is much larger than the size of the circuit on the flexible circuit board. Therefore, the wearable body can be understood as a thicker wire with good conductive performance. Compared with the circuit on the flexible circuit board, the wearable body is used as part of the current loop, which can greatly reduce the conductive impedance in the current loop.

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] As technology continues to improve and demand gradually increases, augmented reality (AR) and virtual reality (VR) technologies can give users a visual experience that is almost the same as the real scene, and are currently hot research areas. In order to enable users to better experience AR and VR technologies, AR and VR are usually displayed using wearable devices.

[0025] For example, taking augmented reality (AR) devices as an example, the principle of augmented reality devices is to superimpose computer-generated images on the user's real vision, so that virtual images and real images are seamlessly integrated. In this way, digital images in the virtual world and physical objects in the real world are combined to give users a sensory experience beyond reality.

[0026] In wearable devices, taking AR glasses as an example, its working principle is to project projection light onto the waveguide lens through a micro-projection optical machine. After the projection light is transmitted in the waveguide lens, it enters the human eye to form a virtual projection picture.

[0027] In the example of AR glasses, the wearable device may be configured to pass data to and receive data from an external processing device via a signal connection, which may be a wired connection, a wireless connection, or a combination thereof. In other cases, the wearable device may be used as a standalone device, i.e., data processing is performed on the wearable device itself. The signal connection may be configured to carry any kind of data, such as image data (e.g., still images and / or full motion video, including 2D and 3D images), audio, multimedia, voice, and / or any other type of data. The external processing device may be, for example, a game console, a personal computer, a tablet computer, a smart phone, or other type of processing device. The signal connection may be, for example, a universal serial bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth low energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G, or 5G), or the like, or a combination thereof. Additionally, the external processing device may communicate with one or more other external processing devices via a network, which may be or include, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the global Internet, or a combination thereof.

[0028] Understandable, see Figure 1 , Figure 1 A first structural diagram of a wearable device provided in an embodiment of the present application. The wearable device 100 generally includes a wearing body 20, which can be worn on a human body, such as, can be worn on a human head. The wearing body 20 can be equipped with a battery, a display component, an optical device, a sensor, a processor, and the like. In the example of AR glasses, the display component is designed to overlay an image on the user's view of his or her real-world environment, for example, by projecting light into the user's eyes. The wearable device may also include an ambient light sensor, and may also include an electronic circuit system to control at least some of the above components and perform associated data processing functions. The electronic circuit system may include, for example, one or more processors and one or more memories.

[0029] For example, please refer to Figure 1The wearable device includes a wearing body 20 and two optical waveguide components 10. The two optical waveguide components 10 are arranged on the wearing body 20. When the wearing body 20 is worn by a user, one optical waveguide component 10 corresponds to the user's left eye, and the other optical waveguide component 10 corresponds to the user's right eye. The optical waveguide component 10 includes a waveguide lens 11 and a projection optical machine (not shown). The projection optical machine is used to project image light onto the waveguide lens 11. The image light is transmitted in the waveguide lens 11 and then incident on the human eye to form a virtual projection picture.

[0030] It can be understood that the projection optical machine provides light to the waveguide lens 11, and the light includes information and / or images for enhancing the user's observation of the material world. The light from the projection optical machine can be coupled into the waveguide lens 11, and the light undergoes total internal reflection in the waveguide lens 11, and then the light is coupled out of the waveguide lens 11, so that the light can be seen by the user. Among them, the projection optical machine can be a self-luminous active device, such as a micro display, and the projection optical machine can use a planar image source, including but not limited to an image source of an integrated light source or a single image source. For example, electronic devices based on display principles such as OLED (Organic Light-Emitting Diode), LCOS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), MEMS (Micro Electrome Chanical Systems), DMD (Digital Micro-mirror Device), etc. Among them, OLED and LCD are image sources of integrated light sources, and LCOS, MEMS and DMD are single image sources. It should be noted that a single image source also requires an additional light source as an auxiliary light source for the single image source. The requirements for the projection optical machine are that it needs to provide sufficiently strong light and be small enough to occupy as little volume as possible in the wearable device 100. However, various projection optical machines now have their own advantages and disadvantages, and a specific light source needs to be selected through a specific solution.

[0031] It can also be understood that in the wearable device 100, the waveguide lens 11 in one optical waveguide component 10 corresponds to the left eye, and the waveguide lens 11 in another optical waveguide component 10 corresponds to the right eye, so that both the left and right eyes can see the image.

[0032] Taking the wearable device 100 as AR glasses as an example, the wearing body 20 may include two temples 21 and a frame 22, the two temples 21 are respectively connected to the opposite ends of the frame 22, the frame 22 includes two mounting holes, the waveguide lens 11 in one optical waveguide component 10 is installed in one mounting hole, and the waveguide lens 11 in the other optical waveguide component 10 is installed in the other mounting hole.

[0033] Among them, Figure 2 As shown, Figure 2 The second structural diagram of the wearable device provided in the embodiment of the present application. The waveguide lens 11 includes a light coupling end 111 and a light coupling end 112 which are arranged opposite to each other, the light coupling end 111 is used to receive the image light of the projection light machine, and the light coupling end 112 is used to emit the image light to the human eye.

[0034] Exemplarily, the light coupling end 111 of the waveguide lens 11 is provided with a coupling grating, and the light coupling end 112 of the waveguide lens 11 is provided with a coupling grating. A turning grating may also be provided on the waveguide lens 11, and the turning grating is located between the coupling grating and the coupling grating. The coupling grating is used to receive the image light of the projection optical machine, the turning grating is used to receive the light of the coupling grating and transmit the light to expand the pupil, and the coupling grating is used to receive the light of the coupling grating and the turning grating, and couple the light out to the human eye for imaging. The coupling grating can diffract the incident light into different angles for transmission in the waveguide lens 11, and its purpose is to introduce the light of the projection optical machine into the waveguide lens 11 with the maximum efficiency. The period of the coupling grating is designed so that the light diffracts and satisfies the total reflection condition to transmit the image light into the waveguide lens 11. The turning grating can transmit the light in the waveguide lens 11 in one-dimensional or two-dimensional directions, and its purpose is to transmit the internal light along a specific direction, and its function is to expand the pupil of the light image information of the projection optical machine. The out-coupling grating can receive the light transmitted by the turning grating, further expand the pupil and couple it out. Its purpose is to couple the information of the projection optical machine to the human eye evenly and efficiently.

[0035] In order to better adapt to the facial structure of the human body, in the embodiment of the present application, the waveguide lens 11 is tilted from the light coupling end 112 toward the light coupling end 111 and toward the direction close to the human eye. Figure 2 As shown, an obtuse angle less than 180 degrees is formed between the two waveguide lenses 11. It can be understood that the angle of the frame 22 is also adapted to the setting angle of the waveguide lenses 11. In this way, the wearing comfort of the wearable device 100 can be improved, and the appearance of the wearable device 100 can also be made more beautiful.

[0036] The inclination angle of the waveguide lens 11 may be greater than 0 degrees and less than or equal to 30 degrees. For example, the inclination angle of the waveguide lens 11 may be 10 degrees, 15 degrees, 20 degrees, 25 degrees or 30 degrees.

[0037] Please note that Figure 1 In the wearable device 100, it is usually necessary to control various functional devices in the wearable device 100 through the mainboard 30, such as at least one of a projection light machine, a sensor, a restarter, a fan, a microphone and a speaker. It is also understandable that the mainboard needs to be powered by a battery to achieve normal functions. Among them, the mainboard 30, the battery 40 and the functional devices are all arranged on the wearable body 20 of the wearable device.

[0038] Exemplarily, the wearing body 20 is provided with a mounting cavity, such as, see Figure 1 The temple 21 of the wearing body 20 is provided with a mounting cavity, and the main board 30 and the battery 40 are arranged in the mounting cavity.

[0039] The mainboard 30 may be a main control board to realize the control function. It should be noted that the mainboard 30 is usually a rigid circuit board. Since the wearable device 100 such as AR glasses has a foldable feature, a flexible printed circuit (FPC) is required.

[0040] It should be noted that current wearable devices tend to be lightweight and thin in design, and legs such as temples tend to be narrower and thinner in design. Batteries, motherboards and other components need to be installed in the effective leg space. The motherboard needs to be connected to other devices such as batteries through a flexible circuit board, and the battery provides power to the motherboard.

[0041] In the related art, the flexible circuit board is usually provided with a power line, and the main board and the battery are electrically connected through the power line on the flexible circuit board, so that the battery can provide power to the main board. Among them, due to the limited installation space of the wearable device, the width of the flexible circuit board in the related art is set to be relatively narrow, and the flexible circuit board is also provided with a signal line, resulting in a narrow routing width of the power line on the flexible circuit board, which cannot effectively reduce the conductive impedance of the power line, that is, it cannot effectively reduce the conductive impedance in the current loop.

[0042] It is understandable that when the conductive impedance in the current loop is large, the voltage drop in the battery discharge path will be too large, which will cause the wearable device system to be unable to work stably for a long time. In addition, the large conductive impedance in the current loop will also cause the circuit to heat up, reduce energy efficiency, and affect the service life of the wearable device.

[0043] It should also be noted that in the related art, in order to reduce the conductive impedance in the current loop, the routing layer of the power supply line on the flexible circuit board is usually thickened. However, increasing the thickness of the routing layer of the power supply line will indirectly increase the thickness of the flexible circuit board. Thus, the increase in the thickness of the routing layer of the power supply line will have a certain impact on the bending flexibility of the flexible circuit board. If the thickness of the routing layer of the power supply line is too thick, the flexible circuit board will be difficult to bend.

[0044] Alternatively, in order to reduce the conductive impedance in the current loop, in the related art, the number of layers of the flexible circuit board is increased, from the conventional two-layer flexible circuit board to a four-layer or six-layer flexible circuit board. By increasing the number of layers of the flexible circuit board, some circuits such as signal circuits can be distributed to each layer of the flexible circuit board, so that each layer of the flexible circuit board has enough space to set the power line, and then the routing width of the power line in each layer of the flexible circuit board can be increased to reduce the conductive impedance in the current loop. However, in addition to increasing the thickness of the flexible circuit board, increasing the number of layers of the flexible circuit board will also increase the production cost and production cycle of the flexible circuit board, and also occupy the installation space of the wearable device, which means that the wearable device cannot be miniaturized.

[0045] In addition, in the related art, in order to reduce the conductive impedance in the current loop, the size of the wearable device is widened to allow a larger installation size for installing the flexible circuit board, so that the width of the flexible circuit board can be widened to increase the width of the power line. However, increasing the size of the wearable device will directly affect the appearance design of the wearable device, making it impossible to design the wearable device in a miniaturized form.

[0046] Based on this, the embodiment of the present application provides a wearable device, in which the wearable body is configured to have conductivity. Figure 3 Combined with Figure 1 , Figure 3 A schematic diagram of the connection between the battery, flexible circuit board, main board and wearable body provided in an embodiment of the present application. The flexible circuit board 50 of the wearable device 100 includes a first circuit 51. The main board 30 of the wearable device 100 includes a first electrode 31 and a second electrode 32. The battery 40 of the wearable device 100 is used to power the main board 30, wherein the battery 40 includes a third electrode 41 and a fourth electrode 42, the third electrode 41 is electrically connected to the first electrode 31 through the first circuit 51, and the fourth electrode 42 is electrically connected to the second electrode 32 through the wearable body 20.

[0047] The wearable device 100 provided in the embodiment of the present application electrically connects the third electrode 41 of the battery 40 with the first electrode 31 of the main board 30 through the first circuit 51 in the flexible circuit board 50, and electrically connects the fourth electrode 42 of the battery 40 with the second electrode 32 of the main board 30 through the conductive wearable body 20. In this way, the wearable body 20 and the first circuit 51 of the flexible circuit board 50 can be used to realize a complete current loop between the battery 40 and the main board 30, that is, the battery 40 supplies power to the main board 30. Compared with the related art that sets the entire current loop on the flexible circuit board 50, when the size of the flexible circuit board 50 remains unchanged, since the wearable body 20 is used as part of the current loop, there is more space on the flexible circuit board 50 of the present application to set the first circuit 51, that is, the width of the first circuit 51 can be made wider, which effectively reduces the conductive impedance in the current loop. In other words, when the conductive impedance remains unchanged, the flexible circuit board 50 of the present application can be set smaller, which is more conducive to the miniaturization design of the wearable device 100. In addition, it can be understood that when the wearable body 20 is used as part of the current loop, generally speaking, the size of the wearable body 20 itself is much larger than the size of the line on the flexible circuit board 50. Therefore, the wearable body 20 can be understood as a thicker wire with good conductive properties. Compared with the line on the flexible circuit board 50, the wearable body 20 is used as part of the current loop, which can greatly reduce the conductive impedance in the current loop.

[0048] Among them, the third electrode 41 of the battery 40 is the positive electrode of the battery 40, and the fourth electrode 42 of the battery 40 is the negative electrode of the battery 40. In this way, the current flows from the positive electrode of the battery 40 to the first electrode 31 of the main board 30 through the first line 51 of the flexible circuit board 50, and flows from the second electrode 32 of the main board 30 to the wearable body 20, and then flows back to the negative electrode of the battery 40, thereby realizing the return of the entire current loop. In this way, even if the wearable body 20 is set to be conductive, there is no risk of short circuit caused by the human body touching the wearable body 20, and safety is higher.

[0049] Understandable, see Figure 3 The flexible circuit board 50 also includes a board body 52, a solder pad 53, a first sub-circuit 54 and a second sub-circuit 55, wherein the board body 52 is provided with a first circuit 51, one end of the first circuit 51 is electrically connected to the third electrode 41 of the battery 40, and the other end of the first circuit 51 is electrically connected to the first electrode 31 of the main board 30.

[0050] The pad 53 is provided on the board body 52, the first sub-circuit 54 is provided on the board body 52, one end of the first sub-circuit 54 is electrically connected to the fourth electrode 42 of the battery 40, and the other end of the first sub-circuit 54 is electrically connected to the pad 53. The second sub-circuit 55 is provided on the board body 52, one end of the second sub-circuit 55 is electrically connected to the pad 53, and the other end of the second sub-circuit 55 is electrically connected to the second electrode 32 of the main board 30. Among them, the pad 53 is also electrically connected to the wearing body 20. In this way, a complete current loop between the battery 40 and the main board 30 is formed by the first circuit 51, the second sub-circuit 55, the pad 53, the wearing body 20 and the first sub-circuit 54, that is, the battery 40 supplies power to the main board 30. It can be understood that the size of the wearing body 20 itself is much larger than the size of the circuit on the flexible circuit board 50. Therefore, the wearing body 20 can be understood as a thicker wire with good conductive performance. Compared with the circuit on the flexible circuit board 50, using the wearing body 20 as part of the current loop can greatly reduce the conductive impedance in the current loop.

[0051] Furthermore, it can be understood that compared to setting a complete current loop on the flexible circuit board 50, when the size of the flexible circuit board 50 remains unchanged, since the wearable body 20 is used as part of the current loop, there is more space on the flexible circuit board 50 to set the first circuit 51, that is, the width of the first circuit 51 can be made wider, effectively reducing the conductive impedance in the current loop. In other words, when the conductive impedance remains unchanged, the flexible circuit board 50 of the present application can be set smaller, which is more conducive to the miniaturization design of the wearable device 100.

[0052] The wearing body 20 may be made of conductive material as a whole, such as conductive metal. For example, the wearing body 20 may include two temples 21 and a frame 22, wherein the two temples 21 are respectively connected to opposite ends of the frame 22, and the frame 22 includes two mounting holes, wherein one waveguide lens 11 is mounted in one mounting hole, and the other waveguide lens 11 is mounted in the other mounting hole. It can be understood that both the temples 21 and the frame 22 may be made of conductive material.

[0053] Of course, it is also understandable that the wearing body 20 may be conductive or a part of the wearing body 20 may be conductive, such as the temple 21 or the frame 22 may be configured to be conductive. This application does not limit this.

[0054] It can be understood that the wearing body 20 is provided with an installation cavity, and the main board 30, the battery 40 and the flexible circuit board 50 are arranged in the installation cavity. For example, one of the temples 21 of the wearing body 20 is provided with a first cavity, the other temple 21 of the wearing body 20 is provided with a second cavity, and the frame 22 is provided with a third cavity, wherein the third cavity connects the first cavity and the second cavity, and the first cavity, the second cavity and the third cavity together define the installation cavity. Exemplarily, the main board 30 can be provided in the first cavity, the battery 40 can be provided in the second cavity, the flexible circuit board 50 can be provided in the third cavity and partially located in the first cavity to connect with the main board 30, and the flexible circuit board 50 is partially located in the second cavity to connect with the battery 40.

[0055] In some embodiments, see Figure 4 , Figure 4 A schematic diagram of a first structure of a flexible circuit board connected to a wearable body provided in an embodiment of the present application. In order to improve the electrical connection stability between the pad 53 and the wearable body 20, the wearable device 100 may further include a conductive spring 60, which is electrically connected between the pad 53 and the wearable body 20. The conductive spring 60 achieves a stable conductive connection between the pad 53 and the wearable body 20.

[0056] Among them, in order to further improve the conductive stability between the conductive spring 60 and the pad 53 and the wearing body 20. The wearable device 100 may also include a pressure plate 70, which is arranged on the side of the plate body 52 of the flexible circuit board 50 away from the conductive spring 60, so as to press the conductive spring 60 between the pad 53 and the wearing body 20. It can be understood that the pressure plate 70 is located at the position where the conductive spring 60 is located, and the pressure plate 70 can apply a force toward the wearing body 20 to the plate body 52 of the flexible circuit board 50, so that the plate body 52 of the flexible circuit board 50 can apply pressure to the conductive spring 60, so that the conductive spring 60 can be pressed between the pad 53 and the wearing body 20, so as to achieve a firm electrical connection between the pad 53, the conductive spring 60 and the wearing body 20.

[0057] It can be understood that the conductive spring piece 60 has a certain elasticity. When the pressure plate 70 is pressed on the side of the board body 52 of the flexible circuit board 50 away from the conductive spring piece 60, the conductive spring piece 60 undergoes elastic deformation to achieve a stable electrical connection between the pad 53 and the wearing body 20.

[0058] For example, please refer to Figure 4The conductive spring sheet 60 includes a connecting portion 61 and an abutting portion 62, wherein the connecting portion 61 is connected to the pad 53, the abutting portion 62 is bent and connected to one end of the connecting portion 61, and the abutting portion 62 is used to abut against the wearing body 20, wherein a deformation space 63 is defined between the connecting portion 61 and the abutting portion 62. It can be understood that when the pressing plate 70 is pressed on the side of the plate body 52 of the flexible circuit board 50 away from the conductive spring sheet 60, the abutting portion 62 abuts against the wearing body 20, and the deformation space 63 formed between the connecting portion 61 and the abutting portion 62 enables the conductive spring sheet 60 to have an avoidance position for deformation, so that the conductive spring sheet 60 can be elastically deformed.

[0059] In some embodiments, the conductive spring sheet 60 can be provided in multiple numbers, and the multiple conductive spring sheets 60 are provided in parallel. For example, the conductive spring sheets 60 can be provided in two, three or four numbers. In this way, the conductive stability of the wearing body 20 can be improved, and the conductive spring sheets 60 connected in parallel can further reduce the conductive impedance.

[0060] It can be understood that the pads 53 on the flexible circuit board 50 are electrically connected to the wearing body 20 through the conductive spring clips 60. When the number of conductive spring clips 60 is multiple, the number of pads 53 on the flexible circuit board 50 is also multiple, and the number of pads 53 on the flexible circuit board 50 corresponds to the number of conductive spring clips 60.

[0061] It is also understandable that the specific number and location of the conductive springs 60 can be set according to actual conditions, such as Figure 5 As shown, Figure 5 The schematic diagram of the structure of the flexible circuit board provided in the embodiment of the present application is as follows: Two conductive springs 60 are provided, and the conductive springs 60 are provided at position 1 and position 2 of the board body 52 of the flexible circuit board 50 .

[0062] In some embodiments, the pad 53 and the wearable body 20 can also be electrically connected through the conductive adhesive layer 80, such as, for example, Figure 6 , Figure 6 A second structural diagram of the flexible circuit board and the wearable body provided in the embodiment of the present application. The wearable device 100 may include a conductive adhesive layer 80, which is connected between the pad 53 and the wearable body 20. In this way, the conductive adhesive layer 80 plays a connecting role as well as a conductive role, so that a stable and reliable electrical connection can be achieved between the pad 53 and the wearable body 20.

[0063] It can be understood that in some embodiments, the conductive adhesive layer 80 and the conductive spring 60 can exist at the same time, for example, the conductive adhesive layer 80 can be provided on two opposite sides of the conductive spring 60, the side of the conductive spring 60 facing the pad 53 is electrically connected to the pad 53 through the conductive adhesive layer 80, and the side of the conductive spring 60 facing the wearing body 20 is electrically connected to the wearing body 20 through the conductive adhesive layer 80. Alternatively, the conductive adhesive layer 80 can be provided on the side of the conductive spring 60 facing the wearing body 20, for example, the conductive spring 60 is connected to the pad 53 by welding, and the side of the conductive spring 60 facing the wearing body 20 is electrically connected to the wearing body 20 through the conductive adhesive layer 80.

[0064] In some embodiments, see Figure 7 , Figure 7 A third structural schematic diagram of the connection between the flexible circuit board and the wearing body provided in the embodiment of the present application. The wearable device 100 may include a fastener 90, which is inserted between the board body 52 and the wearing body 20 to electrically connect the pad 53 to the wearing body 20. It can be understood that when the fastener 90 is inserted between the board body 52 and the wearing body 20, the board body 52 can be fixed to the wearing body 20, and under the connection action of the fastener 90, the pad 53 and the wearing body 20 can be abutted against each other to achieve electrical connection. For example, the fastener 90 can be a screw, and both the board body 52 and the wearing body 20 are provided with screw holes, and the fastener 90 is screwed into the screw hole to achieve the effect of fixed connection.

[0065] In order to further improve the conductivity, please refer to Figure 8 , Figure 8 A fourth structural schematic diagram of the connection between the flexible circuit board and the wearing body provided in the embodiment of the present application. The fastener 90 can be a conductive member, that is, the fastener 90 has conductivity. At this time, the pad 53 is provided with a first connection hole, the wearing body 20 is provided with a second connection hole, and the fastener 90 is passed through the first connection hole and the second connection hole to electrically connect the pad 53 to the wearing body 20. It can be understood that when the fastener 90 is passed through the first connection hole and the second connection hole, since the fastener 90 has conductivity, the fastener 90 can not only play the role of connection and fixing, but also play the role of electrically conducting the pad 53 and the wearing body 20, so that the electrical connection between the pad 53 and the wearing body 20 is more stable and reliable.
