[0052] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no order or technical meaning. Unless otherwise specified, "connection", "coupling" in this application includes direct and indirect connection (coupling).

[0053] Common wireless adapters are limited by their structure size, application scenarios and other factors, and generally have a built-in antenna (for example, an antenna structure formed by etching antenna lines on a rigid printed circuit board (PCB)) in the adapter shell. The wireless adapter can receive and transmit signals in a certain frequency band through the built-in antenna. However, this also causes a series of problems such as narrow frequency band, small signal coverage, short signal transmission distance, and poor directivity.

[0054] The wireless adapter provided by the present application can form a composite antenna inside the adapter by the first antenna and the second antenna. The structure of the first antenna and the second antenna intersecting with each other in the plane can realize the complementarity of the directivity of the two antennas. Compared with related wireless adapters, the wireless adapter provided by the present application has a wider frequency band, a larger signal coverage, and a longer signal transmission distance.

[0055] Please refer to FIGS. 1-9, the present application provides a wireless adapter, which can be applied to earphones, smart glasses, watches, bracelets and other wearable devices to support data information interaction between wearable devices and external devices such as mobile phones and computers. The wireless adapter includes a shell assembly 100, an interface assembly 200, an antenna assembly 300, and other functional components as needed.

[0056] For a clearer and more detailed description of the wireless adapter, please refer to FIG. 1. Three mutually orthogonal directions are defined based on the overall structure of the wireless adapter, namely the length direction, the thickness direction and the width direction. The length direction can refer to the insertion direction of the wireless adapter when it is applied.

[0057] Please refer to FIGS. 1-6, the shell assembly 100 and the interface assembly 200 are connected and arranged along the length direction to form the general outline structure of the wireless adapter. It can be understood that the interface assembly 200 is arranged at one end of the shell assembly 100 along the length direction. The interface assembly 200 is mainly used as a signal and structural connection carrier between the wireless adapter and the wearable device, for example, the wireless adapter can be plugged into the wearable device through the interface assembly 200, thereby establishing a signal and structural connection relationship between the wearable device and the wireless adapter.

[0058] For example, the interface assembly 200 can be a Type-C interface, a USB interface, a Lighting interface, and other interface structures, which are selected and arranged according to needs, and are not limited herein.

[0059] Referring to FIG. 2 and FIG. 3, the shell assembly 100 has an accommodating cavity 100a formed therein, and the antenna assembly 300 is arranged in the accommodating cavity 100a in the form of an electrically connected interface assembly 200. Through the antenna assembly 300, data information (or wireless signals) can be received, transmitted, converted, processed, and the like, so that when the wireless adapter is applied to a wearable device, a data information interaction relationship can be established between the wearable device and external devices.

[0060] In one embodiment, referring to FIG. 2 to FIG. 5, the antenna assembly 300 includes a first antenna 310, a second antenna 320, and a wireless module (not shown in the figure).

[0061] The wireless module can be used to realize transmission, conversion, processing, and the like of data information, and the interface assembly 200, the first antenna 310, and the second antenna 320 are electrically connected to the wireless module.

[0062] Exemplarily, the wireless module can include radio frequency chips, microcontrollers, filters, sensors, and the like different functional types of circuits or elements, and the wireless module is electrically connected between the interface assembly 200 and the first antenna 310 (and the second antenna 320).

[0063] In some embodiments, the wireless module can also be a collection of functional devices independent of the antenna assembly 300 and cooperating with the antenna assembly 300, which will not be described herein.

[0064] The first antenna 310 and the second antenna 320 are arranged in the accommodating cavity 100a in the form that the planes in which the first antenna 310 and the second antenna 320 are located intersect each other, that is, the plane in which the first antenna 310 is located intersects the plane in which the second antenna 320 is located.

[0065] Exemplarily, the plane in which the first antenna 310 is located and the plane in which the second antenna 320 is located are perpendicular to each other in the accommodating cavity 100a or in a three-dimensional space; for example, the plane in which the first antenna 310 is located can be a plane perpendicular to the thickness direction, and the plane in which the second antenna 320 is located can be a plane perpendicular to the length direction or the width direction.

[0066] Exemplarily, the plane in which the first antenna 310 is located and the plane in which the second antenna 320 are obliquely intersected in the accommodating cavity 100a or in a three-dimensional space; for example, the plane in which the first antenna 310 is located can be a plane perpendicular to the thickness direction, and the angle between the plane in which the second antenna 320 is located and the plane in which the first antenna 310 is located is an acute angle or an obtuse angle.

[0067] It should be noted that the description of the "plane where the first antenna 310 is located, the plane where the second antenna 320 is located" in this paper is only for the purpose of clearly and specifically describing the relative spatial position relationship between the first antenna 310 and the second antenna 320; it can be understood that based on the different structural forms of the first antenna 310 and the second antenna 320, the planes where the first antenna 310 and the second antenna 320 are located can be virtual planes or visible planes.

[0068] By forming a composite antenna structure in the accommodating cavity 100a by the first antenna 310 and the second antenna 320, and using the structure form that the planes where the first antenna 310 and the second antenna 320 are located intersect each other, the complementarity of the directivity of the first antenna 310 and the second antenna 320 is realized, and under the cooperation of the wireless module, the antenna assembly 300 or the wireless adapter can receive and transmit signals of a certain frequency band (for example, Bluetooth signals of the 2.4GHz-2.5GHz frequency band).

[0069] At the same time, by comparing and analyzing the performance test of the wireless adapter with the composite antenna structure in the embodiment of the present application and the wireless adapter with the single antenna structure in the related art, it can be found from FIG. 7 that the working bandwidth of the composite antenna is obviously higher than that of the single antenna, from FIG. 8 that the working efficiency of the composite antenna is obviously higher than that of the single antenna, and from FIG. 9 that the signal coverage range of the composite antenna is obviously larger than that of the single antenna.

[0070] Therefore, compared with the existing wireless adapter, the wireless adapter provided by the embodiment of the present application can effectively improve the working bandwidth and working efficiency of the antenna assembly 300 or the wireless adapter, expand the signal coverage range, prolong the signal transmission distance, and enhance the signal strength, etc. by forming a composite antenna structure by the first antenna 310 and the second antenna 320.

[0071] In one embodiment, referring to FIGS. 2-5, the wireless adapter further includes a carrier plate assembly 400 arranged in the accommodating cavity 100a, the carrier plate assembly 400 including a first carrier plate 410 and a second carrier plate 420 fixedly connected to the housing assembly 100; wherein the first antenna 310 is formed on the surface of the first carrier plate 410, and the second antenna 320 is formed on the surface of the second carrier plate 420; for example, the first antenna 310 and the second antenna 320 are arranged on the corresponding carrier plates in the form of etching, printing, or pasting, etc.; the first carrier plate 410 and the second carrier plate 420 are arranged in intersecting manner in the accommodating cavity 100a, so that the plane where the first antenna 310 is located intersects the plane where the second antenna 320 is located.

[0072] Exemplarily, the first carrier plate 410 is arranged in the accommodating cavity 100a in a direction perpendicular to the thickness direction of the wireless adapter; the second carrier plate 420 is arranged in the accommodating cavity 100a in a direction perpendicular to the length direction of the wireless adapter, and is located on the side of the first carrier plate 410 away from the interface assembly 200 in the length direction.

[0073] By arranging the first antenna 310 and the second antenna 320 on different carrier plates, the first antenna 310 and the second antenna 320 can be stably kept in a state of intersecting each other by the first carrier plate 410 and the second carrier plate 420; meanwhile, the relative positions of the first antenna 310 and the second antenna 320 can be adjusted by adjusting the relative positions of the first carrier plate 410 and the second carrier plate 420 in the accommodating cavity 100a, so as to adapt to the internal space structure of the shell assembly 100 or the assembly requirement of the antenna assembly 300.

[0074] In some embodiments, the second carrier plate 420 can be omitted, and the second antenna 420 can be fixedly arranged on the inner wall of the shell assembly 100 (i.e., the inner wall intersecting the plane where the first carrier plate 410 or the first antenna 310 is located) in the form of etching, printing, or attaching, so that the plane where the first antenna 310 is located and the plane where the second antenna 320 is located can intersect each other. In this way, the number of functional components in the wireless adapter can be effectively reduced, which is conducive to enhancing the structural compactness of the wireless adapter and fully utilizing the internal space of the shell assembly 100.

[0075] In one embodiment, the material hardness of the first carrier plate 410 is set to be greater than the material hardness of the second carrier plate 420, for example, the first carrier plate 410 is made of a rigid printed circuit board, and the second carrier plate 420 is made of a flexible printed circuit board (FPC).

[0076] With the relatively stable material properties of the first carrier plate 410, referring to FIGS. 2, 3, and 5, the first carrier plate 410 can be used as a structural arrangement carrier of the main part (e.g., the wireless module and the first antenna 310) of the antenna assembly 300, and the main part of the antenna assembly 300 can be fixed in the accommodating cavity 100a by the structural connection relationship between the first carrier plate 410 and the shell assembly 100. Referring to FIG. 4, the relatively soft material properties of the second carrier plate 420 can be used to fix the second carrier plate 420 (together with the second antenna 320) on the inner wall of the shell assembly 100 (i.e., the cavity wall of the accommodating cavity 100a) in the form of attaching.

[0077] Based on the difference in material hardness between the second carrier plate 420 and the first carrier plate 410, the difference in structural connection form of the shell assembly 100, and the like, on the one hand, the spatial positions of the second carrier plate 420 and the second antenna 320 can be flexibly adjusted according to the internal space structure of the shell assembly 100, so as to ensure that the plane where the first antenna 310 is located intersects the plane where the second antenna 320 is located.

[0078] On the other hand, by fixing the second carrier plate 420 (together with the second antenna 320) on the inner wall of the shell assembly 100, the occupation of the second carrier plate 420 to the limited space of the accommodation cavity 100a can be effectively reduced, or the internal space of the shell assembly 100 can be fully utilized, which creates favorable conditions for enhancing the structural compactness of the wireless adapter, reducing the overall size of the wireless adapter, and the like, so that the wireless adapter can adapt to the application requirements of the wearable device which is increasingly miniaturized.

[0079] In some embodiments, the first carrier plate 410 and the second carrier plate 420 can also be made of the same material, for example, the first carrier plate 410 and the second carrier plate 420 are both made of rigid printed circuit boards; and based on the structural form of the shell assembly 100, the first carrier plate 410 and the second carrier plate 420 can be fixedly connected to the shell assembly 100 independently of each other, or the first carrier plate 410 and the second carrier plate 420 can be fixedly arranged as a whole (for example, the second carrier plate 420 is fixed to the side of the first carrier plate 410 in the form of intersecting the first carrier plate 410). Therefore, not only the consistency of the material of the carrier plate assembly 400 can be ensured, which creates conditions for reducing the configuration cost of the wireless adapter, but also different structural forms of the antenna assembly 300 can be constructed.

[0080] It should be noted that the bold dashed line in FIG. 2 represents the first antenna 310 and the second antenna 320, and the first antenna 310 shown in FIG. 5 and the second antenna 320 shown in FIG. 6 are only used to represent the setting positions of the first antenna 310 and the second antenna 320, and do not represent the structural size, shape, and the like of the first antenna 310 and the second antenna 320.

[0081] In one embodiment, referring to FIGS. 2 to 5, the shell assembly 100 includes an insulating sleeve 110 and an insulating end cover 120; wherein the insulating sleeve 110 is substantially a shell structure having a preset length in the length direction, for the convenience of distinguishing and describing, the two opposite ends of the insulating sleeve 110 in the length direction are defined as the first end and the second end of the insulating sleeve 110; the first carrier plate 410 is fixedly arranged in the interior of the insulating sleeve 110, and the interface assembly 200 is arranged at the first end of the insulating sleeve 110.

[0082] The insulating end cover 120 is arranged at the second end of the insulating sleeve 110 to form the accommodating cavity 100a between the insulating sleeve 110 and the insulating end cover 120. The insulating end cover 120 can be fixedly arranged at the second end of the insulating sleeve 110 in the form of bonding, clamping, locking, welding, etc. For the purpose of distinguishing and description, the wall surface of the insulating end cover 120 facing the insulating sleeve 110 in the length direction or the wall surface as the cavity wall of the accommodating cavity 100a is defined as the inner wall of the insulating end cover 120, and the second carrier plate 420 is fixedly arranged on the inner wall of the insulating end cover 120, for example, the second carrier plate 420 in the form of a flexible printed circuit board is fixedly arranged on the inner wall of the insulating end cover 120.

[0083] Therefore, the shell assembly 100 is formed by combining the insulating sleeve 110 and the insulating end cover 120, and the first carrier plate 410 (together with the first antenna 310) and the second carrier plate 420 (together with the second antenna 320) are fixedly arranged on different components of the shell assembly 100, which can effectively reduce the assembly difficulty of the antenna assembly 300 and even the wireless adapter, and can also be used for targeted disassembly, maintenance or updating of the components to which the first antenna 310 and the second antenna 320 belong.

[0084] In some embodiments, the second antenna 320 can be arranged on the inner wall of the insulating end cover 120 in the form of etching, printing, attaching, etc. in the case of omitting the second carrier plate 420, so that the structural space of the shell assembly 100 can be fully utilized as a structural arrangement carrier of the antenna.

[0085] In one embodiment, referring to FIGS. 2, 3 and 5, the antenna assembly 300 further comprises a feed point structure, which comprises an elastic member 330 (for example, an elastic flap, an elastic column or the like conductive body capable of elastic deformation), the elastic member 330 having a fixed end fixed in the length direction relative to the first carrier plate 410 and a free end movable relative to the first carrier plate 410; wherein the fixed end of the elastic member 330 is fixed to the first carrier plate 410 and is in electrical contact connection with the first antenna 310 arranged on the first carrier plate 410.

[0086] When the insulating end cover 120 is assembled at the second end of the insulating sleeve 110, the free end of the elastic member 330 can be pressed in the length direction by the insulating end cover 120, so that the free end of the elastic member 330 is in stable elastic electrical contact with the second antenna 320 arranged on the second carrier plate 420 or the insulating end cover 120. Therefore, the stable electrical contact connection relationship can be established between the first antenna 310 and the second antenna 320 by the elastic member 330 or the feed point structure, so that the first antenna 310 and the second antenna 320 form a monopole antenna structure with complementary directional functions.

[0087] For example, the first antenna 310 and the wireless module are arranged in an electrically connected manner on the first carrier plate 410, and the second antenna 320 is electrically connected to the first antenna 310 through the feed point structure (for example, the elastic member 330). At this time, the second antenna 320 is equivalent to an antenna part formed by extending the first antenna 310 in a different direction.

[0088] In some embodiments, the feed point structure can also adopt other suitable structures, for example, the feed point structure includes a layer of conductive material arranged on the end face of the first carrier plate 410 and electrically connected to the first antenna 310; for another example, the feed point structure includes a wire connected between the first antenna 310 and the second antenna 320.

[0089] In some embodiments, based on the relative positions of the wireless module, the first antenna 310 and the second antenna 320 in the accommodating cavity 100a, the second antenna 320 can also be directly or through the feed point structure electrically connected to the wireless module; for example, the first antenna 310 and the second antenna 320 both adopt monopole antenna structures, and are respectively electrically connected to the wireless module, so as to realize the complementarity of the directivities of the two antennas by using the structure form in which the planes where the first antenna 310 and the second antenna 320 are located intersect.

[0090] In one embodiment, referring to FIGS. 3 to 5, a first positioning structure is formed between the insulating end cover 120 and the second carrier plate 420, and the first positioning structure includes a positioning protrusion 120a and a positioning through hole 420a; wherein the positioning protrusion 120a is arranged along the length direction and protrudes from the inner wall of the insulating end cover 120, and the positioning through hole 420a is arranged along the length direction and penetrates the second carrier plate 420. The number of the positioning protrusions 120a and the positioning through holes 420a can be one or more, and the multiple positioning protrusions 120a and the multiple positioning through holes 420a correspond one by one.

[0091] In the process of stacking and fixing the second carrier plate 420 on the inner wall of the insulating end cover 120, the positioning protrusion 120a is arranged in the corresponding positioning through hole 420a by using the alignment relationship between the positioning protrusion 120a and the positioning through hole 420a, so that the second carrier plate 420 can be quickly and accurately positioned on the inner wall of the insulating end cover 120 to assemble the second antenna 320 on the insulating end cover 120, and it is also beneficial to enhance the stability of the structural connection between the second carrier plate 420 and the insulating end cover 120, so as to avoid affecting the alignment relationship between the second antenna 320 and the feed point structure (or the first antenna 310, the wireless module, etc.) due to the positional deviation of the second antenna 320 on the insulating end cover 120.

[0092] In some embodiments, the first positioning structure can also adopt other suitable structures, such as a groove structure that is adapted to the contour shape of the second carrier plate 420 is arranged on the inner wall of the insulating end cover 120, and the second carrier plate 420 is accommodated by the groove structure, so that the fast positioning between the second carrier plate 420 and the insulating end cover 120 can also be achieved; for example, a notch structure can be arranged at the contour edge position of the second carrier plate 420, and the positioning protrusion 120a and the notch structure are in the positional relationship, so that the positioning between the second carrier plate 420 and the insulating end cover 120 is achieved.

[0093] In other embodiments, based on the different materials or sizes of the second carrier plate 420, the positioning protrusion 120a can also be arranged protruding from the surface of the second carrier plate 420, and a through hole or a slot hole is arranged on the insulating end cover 120 for the positioning protrusion 120a to pass through or insert; for example, when the second carrier plate 420 adopts a rigid printed circuit board, the positioning protrusion 120a can be arranged protruding from the surface of the second carrier plate 420.

[0094] In one embodiment, referring to FIGS. 3 to 5, a fixing structure is arranged between the insulating sleeve 110 and the insulating end cover 120, and the fixing structure includes the positioning and fixing protrusion 120b and the fixing slot hole 110a, and the positioning and fixing clamping protrusion 120c and the fixing clamping slot 110b; wherein the positioning and fixing protrusion 120b is arranged protruding from the inner wall of the insulating end cover 120 along the length direction, and is located at the edge position of the second carrier plate 420 (for example, a plurality of positioning and fixing protrusions 120b are arranged at intervals around the second antenna 320); the fixing slot hole 110a is arranged in the interior of the insulating sleeve 110, and corresponds to the positioning and fixing protrusion 120b one by one. The positioning and fixing clamping protrusion 120c is arranged protruding from the surface of the insulating end cover 120 in the thickness direction or the width direction, for example, a plurality of positioning and fixing clamping protrusions 120c are arranged at intervals on the surface of the insulating end cover 120 in the thickness direction; the fixing clamping slot 110b is arranged in the interior of the insulating sleeve 110 corresponding to the position of the positioning and fixing clamping protrusion 120c.

[0095] In the process of assembling the insulating end cover 120 to the second end of the insulating sleeve 110, the positioning and fixing protrusion 120b is inserted and fitted into the corresponding fixing slot hole 110a by the positional relationship between the positioning and fixing protrusion 120b and the fixing slot hole 110a, so that the positioning between the insulating sleeve 110 and the insulating end cover 120 is achieved; at the same time, the insulating end cover 120 is stably fixed to the insulating sleeve 110 by the positional clamping relationship between the positioning and fixing clamping protrusion 120c and the fixing clamping slot 110b. Since the fixing structure is formed in the interior of the shell assembly 100 (specifically, in the accommodating cavity 100a), the integrity of the shell assembly 100 or the external contour structure of the wireless adapter can also be ensured, which creates favorable conditions for improving the appearance aesthetics of the wireless adapter.

[0096] In some embodiments, the fixing structure can also adopt other suitable structures, for example, the fixing protrusion 120b and the fixing slot hole 110a are omitted, and the contour shape matching relationship between the second end port of the insulating sleeve 110 and the insulating end cover 120 is used to realize the rapid positioning of the two. For another example, the fixing clamping groove 110b and the fixing clamping protrusion 120c are omitted, and the insulating end cover 120 is fixed to the second end of the insulating sleeve 110 by means of gluing, welding and the like; all of these will not be repeated here.

[0097] In one embodiment, referring to FIG. 1, the second positioning structure is formed between the insulating sleeve 110 and the first carrier plate 410, which can include a protruding structure 410a protruding from the surface of the first carrier plate 410 in the thickness direction, and the insulating sleeve 110 is provided with a corresponding structure for positioning and matching (such as clamping, accommodating, etc.) with the second positioning structure.

[0098] By means of the second positioning structure, the position of the first carrier plate 410 fixed or positioned inside the insulating sleeve 110 or the accommodating cavity 100a can be limited, so as to ensure that the first carrier plate 410 and related components (such as the first antenna 310, the elastic member 330, the wireless module, etc.) are relatively stably arranged in the accommodating cavity 100a.

[0099] In some embodiments, the wireless module can be hidden between the protruding structure 410a and the first carrier plate 410, so as to form structural protection for the wireless module by means of the protruding structure 410a.

[0100] In one embodiment, referring to FIGS. 2 to 6, the interface assembly 200 includes an interface shell 210, a third carrier plate 220 and an interface pin 230; wherein the inside of the interface shell 210 is formed with a guide cavity 210a penetrating through the interface shell 210 along the length direction, and one end of the interface shell 210 in the length direction is sleeved on the first end of the insulating sleeve 110 (it can also be understood that one end of the insulating sleeve 110 is inserted into the guide cavity 210a); the third carrier plate 220 is inserted into the guide cavity 210a along the length direction, and the third carrier plate 220 and the first carrier plate 410 are an integral structure (it can be understood that the same carrier plate is divided into the first carrier plate 410 and the third carrier plate 220 in the length direction in structure and function); the interface pin 230 is formed on the surface of the third carrier plate 220, and the interface pin 230 is electrically connected with the antenna assembly 300 (specifically, the wireless module).

[0101] By selecting and setting the structural form or function-implementation of the interface shell 210 or the interface pin 230, the interface assembly 200 can be configured as a Type-C interface, a USB interface, a Lighting interface, or the like, so as to plug the wireless adapter to the wearable device through the interface assembly 200. By setting the first carrier plate 410 and the third carrier plate 220 as an integrated structure, the configuration number of the components of the wireless adapter can be effectively reduced, and the compactness and stability of the wireless adapter structure can be enhanced.

[0102] In some embodiments, the wireless module can be arranged at a position where the first carrier plate 410 and the third carrier plate 220 meet or are critical, for example, the wireless module is arranged at a position where the first carrier plate 410 is close to the third carrier plate 220 in the length direction, or the wireless module is arranged at a position where the third carrier plate 220 is close to the first carrier plate 410 in the length direction. Thus, by arranging the wireless module, the interface pin 230 and the first antenna 310 and their respective arrangement positions can be clearly distinguished.

[0103] In one embodiment, referring to FIGS. 5 and 6, the insulating sleeve 110 further has a support structure 110c which is arranged at the first end of the insulating sleeve 110 in the length direction and is inserted into the guide cavity 210a in the length direction, and the third carrier plate 230 is fixed to the support structure 110c.

[0104] The support structure 110c can not only establish a stable structural connection relationship between the interface shell 210 and the insulating sleeve 110, but also can stably position the third carrier plate 220 (together with the interface pin 230) in the guide cavity 210a. In specific implementation, the support structure 110c can adopt a window structure or a frame structure to avoid structural interference of the support structure 110c to the interface pin 230, and to ensure that the wireless adapter or the interface assembly 200 can establish a signal connection relationship with the wearable device through the interface pin 230.

[0105] In some embodiments, a second positioning structure can be formed between the position where the first carrier plate 410 and the third carrier plate 220 meet and the support structure 110c, so that the first carrier plate 410 and the third carrier plate 220 can be simultaneously positioned and fixed in the accommodating cavity 100a and the support structure 110c by using the second positioning structure, which creates favorable conditions for rapid assembly and molding of the wireless adapter.

[0106] In some embodiments, referring to FIGS. 3-5, the insulating sleeve 110 further has a light guide structure 110d, which can be a light-transmitting or light-conducting material body arranged through the sidewall of the insulating sleeve 110 in the thickness direction, or a through-hole structure arranged through the sidewall of the insulating sleeve 110. Correspondingly, a light-emitting element (e.g., an LED lamp bead or a light-emitting diode, etc.) can be arranged at a position of the first carrier plate 410 corresponding to the light guide structure 110d, and light emitted by the light-emitting element is guided out of the wireless adapter by the light guide structure 110d, so as to display the state of the wireless adapter.

[0107] It should be noted that the wearable device is only a specific application scenario of the wireless adapter provided in the present application, and the wireless adapter can also be applied to other devices. For example, by plugging the wireless adapter into a computer device, data information interaction between the computer device and related devices (e.g., a mouse, a keyboard, or other electronic products) can be achieved. It can be understood that the application scenario does not limit the wireless adapter of the embodiments of the present application.

[0108] The above application of specific examples is used to illustrate the present application, which is only used to help understand the present application, and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
