[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0030] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0031] The terms "installed", "set up", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, components, or parts (the specific types and structures may be the same or different), and do not indicate or imply the relative importance and quantity of the indicated devices, components, or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0033] As described in the background art, EMC refers to the comprehensive assessment of EMI and EMS, or rather, EMC refers to the comprehensive assessment of the interference level and anti-interference ability of a product in the electromagnetic field. EMC is one of the most important indicators of product quality, and the EMC test consists of a test site and test instruments.

[0034] The flipable smartwatch consists of a main body, a base, and a rotating structure connecting the main body and the base. The main body is provided with an antenna and a first metal buckle, and the base includes a metal tray and a first metal hook integrated with the metal tray. By fastening the first metal buckle and the first metal hook, the main body can be fixed on the tray. When the first metal buckle is separated from the first metal hook, the main body can rotate relative to the base through the rotating structure, and the antenna can be used to enable the smartwatch to communicate with the outside world.

[0035] However, when the inventor connected the flip - type smart watch to a communication instrument to test the EMC, it was found that the EMC index of the watch exceeded the national control standard. According to the test results, when the first metal buckle and the first metal hook were buckled, the spurious test result of the third harmonic of the test item GSM1800 (the communication frequency band of the smart watch is 1800 MHz) was - 20 dBm, which was greater than the national control standard of - 30 dBm. The inventor found through research that harmonic problems would occur when the first metal buckle and the first metal hook were buckled. Under the action of the electromagnetic field, induced current was generated on the base. Since the contact surface between the first metal buckle and the first metal hook was not smooth, when this current flowed through the first metal hook, a non - sinusoidal current was formed, resulting in the generation of harmonics and causing EMC problems for the smart watch.

[0036] In view of this, the embodiment of the present application provides a tray assembly. A non - conductor connection structure is connected between the tray and the first locking structure, so that the tray and the first locking structure are insulated from each other. When current is generated on the tray, this connection structure can block the conduction of this current to the first locking structure, thereby reducing the current of the first locking structure, further reducing the harmonic power, and enabling the wearable device to meet the EMC requirements.

[0037] Please refer to Figure 1 , which shows a tray assembly provided by the embodiment of the present application. This tray assembly is used to connect to the host of a wearable device, such as Figure 1As shown, the pallet assembly may include a pallet 100, a first locking structure 200, and a connection structure 300. The connection structure 300 is connected between the pallet 100 and the first locking structure 200 to insulate the pallet 100 and the first locking structure 200 from each other. Among them, the pallet 100 is made of a first conductor material, the first locking structure 200 is made of a second conductor material, and the connection structure 300 is made of a non-conductor material. The pallet 100 can be used to carry the host computer, and the first locking structure 200 is used for detachable connection with a second locking structure and locks the host computer on the pallet 100 when connected to the second locking structure, preventing the host computer from falling off or rotating unexpectedly. Among them, the connection structure 300 being connected between the first locking structure 200 and the pallet 100 may include the connection structure 300 being respectively connected to the first locking structure 200 and the pallet 100, so that the first locking structure 200 is connected to the pallet 100, thereby enabling the host computer to be locked on the pallet 100 when the first locking structure 200 is connected to the second locking structure. Alternatively, the connection structure 300 being connected between the first locking structure 200 and the pallet 100 may also include the connection structure 300 connecting the pallet 100 through a first structure and the connection structure 300 being directly connected to the first locking structure 200. Alternatively, the connection structure 300 being connected between the first locking structure 200 and the pallet 100 may also include the connection structure 300 connecting the pallet 100 directly and the connection structure 300 connecting to the first locking structure 200 through a second structure. Alternatively, the connection structure 300 being connected between the first locking structure 200 and the pallet 100 may also include the connection structure 300 connecting the pallet 100 through a first structure and the connection structure 300 connecting to the first locking structure 200 through a second structure.

[0038] It should be noted that the pallet 100 assembly may include at least one first locking structure 200. The pallet 100 is made of a first conductor material, and it can be understood that the pallet 100 is a conductor. The first locking structure 200 is made of a second conductor material, and it can be understood that the first locking structure 200 is a conductor. The first conductor material and the second conductor material in the embodiments of the present application may be conductor materials composed of multiple conductor materials, or a certain conductor material. The first conductor material and the second conductor material may be the same conductor material or different conductor materials. The connection structure 300 is made of a non-conductor material, and it can be understood that the connection structure 300 is a non-conductor. When the first locking structure 200 is separated (not connected) from the second locking structure, the host can be separated from the pallet 100 assembly or can move relative to the pallet 100 assembly (such as: rotating or sliding). In the embodiments of the present application, when the first locking structure 200 is separated from the second locking structure, the specific situation of the host and the pallet 100 assembly is not limited and can be designed according to needs. In the embodiments of the present application, by connecting the non-conductor connection structure between the first locking structure and the pallet, when the first locking structure is connected to the second locking structure, the host can be locked on the pallet. At the same time, since the non-conductor connection structure is disposed between the pallet and the first locking structure, the pallet and the first locking structure are insulated from each other, which can avoid the harmonic problem caused by the current on the pallet being conducted to the first locking structure. The EMC of the wearable device using the pallet assembly provided in the embodiments of the present application meets the requirements.

[0039] In an alternative embodiment, the connection structure may include a first surface and a second surface. The first surface of the connection structure is connected to the pallet, and the second surface of the connection structure is connected to the first locking structure. The distance between the first surface and the second surface is a preset distance, and the preset distance is positively correlated with the antenna radiation power of the wearable device. It should be noted that when the wearable device is communicating, the electromagnetic field generated by the antenna radiation will cause a current to be generated in the conductive pallet. The stronger the radiation power, the greater the current in the pallet and the greater the impact on the first locking structure, which is a conductor, that is, the greater the induced current generated in the first locking structure. Therefore, the distance between the first surface and the second surface can be set according to the antenna radiation power, which can avoid the current on the pallet being directly conducted to the first locking structure and at the same time can reduce the current generated in the first locking structure due to the electromagnetic induction phenomenon, further reducing the generated harmonics so that the wearable device meets the EMC requirements.

[0040] In an alternative embodiment, the distance between the first surface and the second surface of the connection structure is greater than or equal to 0.3 mm. It should be noted that when the first surface and the second surface are not parallel, the distance between the first surface and the second surface can be the minimum distance between the first surface and the second surface to ensure electrical isolation between the first locking structure and the tray. Optionally, the distance between the first surface and the second surface ranges from 0.3 mm to 0.5 mm. Optionally, the distance between the first surface and the second surface is 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm or 0.50 mm. The distance between the first surface and the second surface determined in this embodiment can enable the wearable device to meet the EMC requirements (when the distance between the first surface and the second surface is 0.30 mm, the spurious test result of the third harmonic of the GSM1800 test item is -33 dBm, which is less than -30 dBm). At the same time, it can avoid the phenomenon that the first locking structure falls off due to the excessive distance between the first surface and the second surface. Optionally, the connection structure can be a hexahedron, and the first surface and the second surface are opposite surfaces to achieve electrical insulation between the first locking structure and the tray. Exemplarily, the hexahedron can be a parallelepiped.

[0041] In an alternative embodiment, the first conductor material and the second conductor material can be stainless steel, aluminum alloy or magnesium alloy, which can increase the structural strength of the tray and the first locking structure to extend the service life of the tray assembly.

[0042] Please continue to refer to Figure 1 , in an alternative embodiment, the tray assembly can further include a rotating structure 400, which is disposed on the tray 100 and is used to connect to the host, so that when the first locking structure and the second locking structure are separated, the host can rotate relative to the tray 100. Optionally, the rotating structure 400 is disposed on the first surface of the tray 100, and the first surface of the tray 100 is the opposite surface of the surface where the tray 100 is connected to the connection structure 300, that is, the second surface of the tray 100 is connected to the connection structure 300, and the first surface and the second surface of the tray 100 are opposite surfaces.

[0043] In an alternative embodiment, the second locking structure can be fixedly connected to the host, so as to lock the host and the tray when the second locking structure is engaged with the first locking structure. In an alternative embodiment, the locking between the tray and the host is achieved through threaded connection. Exemplarily, the host is provided with a threaded hole, and the tray is provided with a connection hole corresponding to the threaded hole, and the connection hole is connected to the threaded hole through a fastener. The threaded hole can be understood as the second locking structure, and the connection hole and the fastener can be understood as the first locking structure. The host and the tray can be locked through the threaded hole, the connection hole and the fastener.

[0044] In an alternative embodiment, the second locking structure is made of a third conductor material, that is, the second locking structure is a conductor. The third conductor material may be a conductor material composed of multiple conductor materials or a certain conductor material. The third conductor material and the first conductor material may be the same or different conductor materials, and the third conductor material and the second conductor material may be the same or different conductor materials. This embodiment does not limit this. In this embodiment, although both the first locking structure and the second locking structure are conductors, when a current is generated in the pallet that is a conductor, since the current on the pallet cannot be conducted to the first locking structure, even if the first locking structure and the second locking structure are connected to form a non-smooth conductor surface, because the first locking structure obtains less current, the harmonic power generated is small compared to the direct connection between the pallet and the first locking structure. Therefore, the wearable device can meet the EMC requirements. Optionally, both the second locking structure and the first locking structure are made of one of stainless steel, aluminum alloy or magnesium alloy. Since the first locking structure and the second locking structure need to be switched between the connected state and the non-connected state, a material with greater strength is used to increase the strength of the second locking structure and extend the service life of the wearable device.

[0045] Please continue to refer to Figure 1 , in an alternative embodiment, the pallet assembly may include two first locking structures 200 and two connecting structures 300. The first surfaces of the two connecting structures 300 are both connected to the second surface of the pallet 100, and the second surfaces of the two connecting structures 300 are respectively connected to the corresponding first locking structures 200. When the pallet assembly includes two first locking structures 200, the two first locking structures 200 are respectively connected to the pallet 100 through the two connecting structures 300, so as to avoid the direct conduction of the current on the pallet 100 to the first locking structure 200, resulting in harmonic problems, and thus the wearable device can meet the EMC requirements.

[0046] In an alternative embodiment, the pallet assembly includes a plurality of first locking structures, and the plurality of locking structures are all connected to the pallet through a connecting structure. Taking Figure 1 the shown pallet assembly as an example, Figure 1 the two connecting structures 300 shown may be an integrally formed connecting structure.

[0047] In an alternative embodiment, the two first locking structures of the pallet assembly are connected to different surfaces of the pallet through two connecting structures. For example: the pallet further includes a third surface, and one of the first locking structures is connected to the second surface of the pallet through one of the connecting structures, and the other first locking structure is connected to the third surface of the pallet through the other connecting structure.

[0048] In an optional embodiment, the first connection structure may be a first catch, and the second connection structure is a second catch that is snap-fitted with the first catch. In this embodiment, the first catch is connected to the pallet through the connection structure. When the first catch is connected to the first catch, the host is locked to the pallet assembly. Optionally, the second catch is provided on the host and fixedly connected to the host.

[0049] Please refer to Figures 2 to 3 , Figure 3 which shows an example diagram of a pallet assembly provided by an embodiment of the present application. Figure 3 is a partial enlarged schematic diagram of the first catch and the connection structure. As Figures 2 to 3 shown, the first catch may include a support portion 210 and an abutting portion 220. The abutting portion 220 is connected to the support portion 210, and the abutting portion 220 corresponds to the first catch, that is, the abutting portion 220 can be snap-connected to the first catch. At least a part of the support portion 210 is disposed in the cavity. The cavity is formed by the second surface of the connection structure 300 recessing inward. It can be understood that a groove is provided on the second surface of the connection structure 300, and this groove is the cavity described in this embodiment.

[0050] It should be noted that there are different implementation manners for the connection between the abutting portion 220 and the support portion 210 of the first catch. Exemplarily, it can be made by integral molding, welding, bonding, threaded connection, etc. Optionally, the abutting portion 220 and the support portion 210 are integrally formed, which can save the assembly steps of the abutting portion 220 and the support portion 210, and at the same time, the connection between the abutting portion 220 and the support portion 210 of the integral molding structure is more stable.

[0051] In this embodiment, a cavity is opened on the connection structure so that at least a part of the support portion of the first catch can be disposed in the cavity, increasing the connection reliability between the first catch and the connection structure, and avoiding the phenomenon that the first catch accidentally falls off when the first catch is connected to the pallet through the connection structure.

[0052] Please continue to refer to Figure 2, the second surface of the connection structure includes a first side surface and a second side surface that enclose a cavity. The support portion 210 of the first hook includes a third side surface and a fourth side surface. Among them, the first side surface extends outward to form a first protrusion, the second side surface extends inward to form a second protrusion, the third side surface is recessed inward to form a first groove corresponding to and receiving the first protrusion, and the fourth side surface is recessed inward to form a second groove corresponding to and receiving the second protrusion. Or it can be understood that the first side surface is provided with the first protrusion, the second side surface is provided with the second protrusion, the third side surface is provided with the first groove corresponding to the first protrusion, and the fourth side surface is provided with the second groove corresponding to the second protrusion. Among them, the first groove corresponds to and receives the first protrusion, and the second groove corresponds to and receives the second protrusion can be understood as that when the first hook is connected to the connection structure, the side surface of the first protrusion contacts the side surface of the first groove, and the side surface of the second protrusion contacts the side surface of the second groove, preventing the first hook from moving relative to the connection structure.

[0053] It should be noted that in addition to the first protrusion and the second protrusion, the cavity can also be provided with more protrusions according to needs. Correspondingly, the support portion 210 can also be provided with more corresponding grooves to further improve the connection reliability between the first hook and the connection structure.

[0054] Optionally, the first side surface and the second side surface of the connection structure are opposite surfaces, and the third side surface and the fourth side surface of the support portion are opposite surfaces. In this embodiment, the first protrusion and the second protrusion are respectively provided on the opposite surfaces of the connection structure, and the first groove corresponding to the first protrusion and the second groove corresponding to the second protrusion are provided on the opposite surfaces of the support portion. Compared with providing protrusions on the adjacent surfaces of the second surface of the connection structure and providing corresponding grooves on the adjacent surfaces of the support portion, the connection reliability between the support portion and the connection structure can be improved. Optionally, the material of the connection structure can be plastic, and the material of the first hook can be stainless steel. In this embodiment, after forming the connection structure and the first hook, the connection between the first hook and the connection structure can be realized by pressing the first hook with an external force, which is convenient for the assembly of the first hook and the connection structure. At the same time, when the first hook needs to be replaced, the first hook can be separated from the connection structure by applying a certain external force to replace the first hook. Compared with welding, bonding and other methods to realize the connection between the first hook and the connection structure, when replacing the first hook, there is no need to replace the connection structure, saving costs.

[0055] In an alternative embodiment, the material of the first hook can be one of stainless steel, aluminum alloy or magnesium alloy. In an alternative embodiment, the material of the first buckle can be one of stainless steel, aluminum alloy or magnesium alloy. Stainless steel, aluminum alloy or magnesium alloy have high structural strength. The first hook or the first buckle made of stainless steel, aluminum alloy or magnesium alloy has high structural strength, which can extend the service life of the tray assembly and the wearable device.

[0056] Please refer to Figure 4 , which shows a tray assembly provided by an embodiment of the present application. As Figure 4 shown, the difference between the tray assembly provided in this embodiment and the tray assembly shown in Figure 1 is that the tray assembly provided in this embodiment is provided with an opening 500, and this opening 500 can be used to set an attitude detection device, wherein the attitude detection device is used to detect the attitude of the wearable device. Exemplarily, the wearable device may include a first attitude and a second attitude. The first attitude is the attitude where the host is stacked on the tray, and the second attitude is the state where the host is separated from the tray, such as when the host and the tray form a certain angle.

[0057] In an optional embodiment, the host can determine the attitude of the wearable device through the attitude detection device. Optionally, when the host determines that the wearable device is in the second attitude, a preset first operation is executed. Exemplarily, the wearable device includes a camera, and the preset first operation can be to turn on the camera. In this embodiment, through the attitude detection device, it can be realized that when the wearable device switches to the second attitude, the first operation is automatically executed without the user manually executing the first operation, improving the user experience.

[0058] In an optional embodiment, the attitude detection device may include a magnet and a first switch. Among them, the first switch is in a closed state when the distance from the magnet is less than or equal to a first distance, and the first switch is in an open state when the distance from the magnet is greater than the first distance. The magnet is arranged in the opening of the tray, and the first switch can be arranged on the first circuit of the host. By determining the on-off of the first circuit, the distance between the host and the tray can be determined, and thus the function of determining the attitude of the wearable device can be realized. It should be noted that the attitude detection device described in this embodiment is only an exemplary structure, and this embodiment does not limit the structure of the attitude detection device, as long as it can realize the function of detecting the attitude of the wearable device.

[0059] Please continue to refer to Figure 4 , which shows a tray assembly provided by an embodiment of the present application. As Figure 4 shown, compared with the tray assembly provided in the above embodiment, this tray assembly may further include a non-conductor layer 600. Among them, the non-conductor layer 600 at least partially covers the tray 100. The tray assembly provided in this embodiment covers the tray 100 through the non-conductor layer 600, which can protect the tray 100. At the same time, when using the wearable device, the host may generate heat. By covering the non-conductor layer 600 on the tray 100, the heat transferred to the human body can be reduced. Optionally, the non-conductor layer 600 may include a plastic layer.

[0060] In an alternative embodiment, the tray includes opposite first and second surfaces. When the main body is locked to the tray, the first surface is the side of the tray close to the main body. The non-conductive layer can cover one of the first surface or the second surface, or can cover both the first surface and the second surface to surround the tray. In an alternative embodiment, the non-conductive layer connects the rotating structure to the tray so that the main body can rotate relative to the tray. In this embodiment, the connection between the rotating structure and the tray is realized through the non-conductive layer. Compared with connecting the rotating structure and the tray by means such as welding or bonding, the separate preparation of the rotating structure and the tray can be achieved. And in the case where one of the rotating structure and the tray is damaged, only one of the rotating structure or the tray can be replaced, without replacing both together, thus saving costs.

[0061] In an alternative embodiment, the non-conductive layer and the connection structure can be an integrally formed structure. Optionally, the materials of the non-conductive layer and the connection structure are both plastics. The non-conductive layer covering the tray and the connection structure connected to the tray are formed by an injection molding process, so that the connection between the connection structure and the tray is more stable. Optionally, please continue to refer to Figure 4 , positioning holes are provided on the tray to improve the accuracy of the injection molding process. Among them, the number and shape of the positioning holes can be set as needed, and this embodiment does not limit this. As Figure 4 shown, there are 8 positioning holes on the tray, namely the first positioning hole 701, the second positioning hole 702, the third positioning hole 703, the fourth positioning hole 704, the fifth positioning hole 705, the sixth positioning hole 706, the seventh positioning hole 707 and the eighth positioning hole 708.

[0062] Please refer to Figure 5 , this embodiment of the present application also provides a wearable device. Figure 5 As shown, the main body of the wearable device is locked to the tray. The wearable device can be a flipable wearable device, and the wearable device can be a bracelet, a watch, an ankle bracelet or a neck ring. As Figure 5 shown, the wearable device can include a main body 800 and the tray assembly 900 provided in any of the above embodiments. The main body 800 is connected to the tray assembly 900, and the tray assembly 900 is used to carry the main body 800. Optionally, the main body 800 is rotatably connected or detachably connected to the tray assembly 900.

[0063] In the tray assembly of the wearable device provided in this embodiment, the non-conductive connection structure is connected between the tray and the first locking structure, insulating the tray and the first locking structure from each other. Therefore, even if current is generated on the tray, it cannot be directly conducted to the first locking structure, thereby reducing the harmonic power generated due to the uneven contact surface between the first locking structure and the second locking structure, solving the EMC problem, and enabling the wearable device to meet the EMC requirements.

[0064] In an optional embodiment, the host is provided with an antenna assembly, which can be used to receive or transmit signals. Optionally, the antenna assembly can be used to receive or transmit signals in the frequency band of 1800 MHz. Optionally, the host may include a host body and a host housing. The host body includes the antenna assembly, and the antenna assembly is disposed on the bottom plate of the host.

[0065] Optionally, the host body may further include, but is not limited to, a speaker, a camera, a battery, and a charging interface. In an optional embodiment, the battery is disposed on the bottom plate of the host housing, and the charging interface, the speaker, and the camera are disposed on the host housing. The battery is electrically connected to the charging interface.
