[0019] In some embodiments, the antenna body has a first through hole;
[0020] The connecting surface is provided with a plurality of steps along the edge of the first through hole.
[0021] In some embodiments, the ground spring has a second through hole; the second through hole is aligned with the first through hole of the antenna body;
[0022] The surface of the antenna body provided with the first through hole and facing the ground spring constitutes the connecting surface.

[0042] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. In the following description, the same numbers refer to the same or similar elements unless otherwise represented. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0043] The antenna structure according to the embodiments of the present disclosure is applied to the scenario of electrically connecting a grounding spring and an antenna body, and the failure of electrically connecting is reduced by setting different distances from different contact surfaces connected with the contacts to the spring body, thereby improving the reliability of the antenna electrically connecting.
[0044] Figure 1 FIG. 1 is a schematic diagram of an antenna structure according to an exemplary embodiment of the present disclosure. Figure 2 FIG. 2 is a schematic diagram of a grounding spring in the antenna structure according to an exemplary embodiment of the present disclosure. As shown in Figure 1 and Figure 2 The antenna structure includes an antenna body 100 and a grounding spring 200.
[0045] The antenna body 100 has at least two contact surfaces 101 on a connecting surface (not shown in the figure) connected with the grounding spring 200.
[0046] The grounding spring 200 includes a spring body 201 and a plurality of contacts 202 formed on the spring body 201.
[0047] The at least two contacts 202 are connected with different contact surfaces 101.
[0048] The different contact surfaces 101 have different distances to the spring body 201.
[0049] In the embodiments of the present disclosure, the antenna structure is used for transmitting and receiving wireless signals, and can transmit and receive Bluetooth (BT), WiFi, GPS, Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), satellite communication, and other wireless communication.
[0050] It should be noted that the antenna structure can be applied to an electronic device, which includes a smart phone, a tablet computer, a notebook computer, a wearable device, a personal digital assistant (PDA), and the like. The wearable device includes, but is not limited to, a smart watch or a smart bracelet.
[0051] In the embodiments of the present disclosure, the antenna body is formed of a conductive material. The conductive material includes aluminum alloy, stainless steel, liquid metal, etc., and the embodiments of the present disclosure are not limited in this regard.
[0052] It should be noted that the antenna structure is applied to an electronic device. In some embodiments, the conductive frame of the electronic device can be reused as the antenna body; in other embodiments, the electronic device can further include a non-conductive frame, and the antenna body is arranged in the non-conductive frame.
[0053] In the embodiments of the present disclosure, the grounding spring sheet includes a spring body and a plurality of contacts formed on the spring body. The contacts can be formed protruding from the spring body towards the antenna body.
[0054] Here, the grounding spring sheet can be composed of a spring material. The spring material includes titanium copper or stainless steel, etc. The contacts can be gold plated to better electrically connect the contacts with the antenna body.
[0055] It should be noted that the plurality of contacts are distributed at intervals on the spring body. The shape of each contact can be the same or different, and the distance between adjacent two contacts can be the same or different.
[0056] Exemplarily, the shape of the contacts can include a columnar shape or a semicircular shape, etc., and the embodiments of the present disclosure are not limited in this regard.
[0057] In the embodiments of the present disclosure, the distances from the different contact surfaces to the spring body are different. That is, the connection surface is not a plane, but is composed of a plurality of contact surfaces with different heights.
[0058] Exemplarily, as shown in Figure 1 and Figure 2 , the connection surface of the antenna body 100 connected with the grounding spring sheet 200 has three contact surfaces 101. The distances from the three contact surfaces 101 to the spring body 201 are different. That is, the antenna body 100 has three contact surfaces 101 with different heights.
[0059] In the embodiments of the present disclosure, the contact surface is used to contact the contact, and the contact surface can be a contact plane or a contact curved surface.
[0060] In some embodiments, as shown in Figure 1 and Figure 2 , the contact surface 101 includes a contact plane, and the contact plane is parallel to the spring body 201.
[0061] It should be noted that the contact plane parallel to the spring body can include that the contact plane is parallel to the surface of the spring body facing the contact surface. Here, the surface of the spring body facing the contact surface can be a plane.
[0062] It should be noted that when the surface of the spring body facing the contact surface is not a plane, i.e., the spring arm formed by the spring body is inclined relative to the antenna body, the contact surface can be parallel to the spring plane of the spring arm, and the included angle between the contact surface and the spring plane of the spring arm can be an acute angle.
[0063] It can be understood that by arranging the contact surface to be parallel to the spring body, the contact surface can better contact the contact on the spring body, and thus the electrical connection between the antenna body and the grounding spring is more reliable.
[0064] In other embodiments, the contact surface can also include a contact curved surface, and the surface of the spring body facing the contact curved surface can also be a spring curved surface, and the spring curved surface and the contact curved surface are mutually matched curved surfaces.
[0065] It should be noted that the spring curved surface and the contact curved surface are mutually matched curved surfaces, which can include that the protrusion of the spring curved surface can be at least partially embedded in the groove of the contact curved surface, and / or the protrusion of the contact curved surface can be at least partially embedded in the groove of the spring curved surface.
[0066] It can be understood that by arranging the spring curved surface and the contact curved surface to be mutually matched curved surfaces, the spring curved surface and the contact curved surface can be more fully contacted, and thus the electrical connection between the antenna body and the grounding spring is more reliable.
[0067] In the embodiments of the present disclosure, the contact surface of the antenna body is the surface in contact with the contact of the grounding spring. Here, the number of contact surfaces can be less than or equal to the number of contacts. In this way, it can be better to connect each contact surface with a contact.
[0068] At least two contacts in the plurality of contacts are connected to different contact surfaces, which can include that all contacts are connected to different contact surfaces, and can also include that a part of the plurality of contacts are connected to different contact surfaces, and another part of the plurality of contacts are connected to the same contact surface.
[0069] It should be noted that when all contacts are connected to different contact surfaces, if the grounding spring includes two contacts, the two contacts can be connected to two different contact surfaces respectively; if the grounding spring includes three contacts, the three contacts can be connected to three different contact surfaces respectively.
[0070] When a part of the plurality of contacts are connected to different contact surfaces, and another part of the plurality of contacts are connected to the same contact surface, if the grounding spring includes four contacts, two of the four contacts can be connected to different contact surfaces, and the other two contacts can be connected to the same contact surface.
[0071] In the process of fixing the antenna body and the grounding spring, an action force is applied to the antenna body and the grounding spring. Because the distances from different contact surfaces to the spring body are different, the action force applied to at least two contacts connected to different contact surfaces is inconsistent when the action force acts on the antenna body and the grounding spring, and thus the wear degrees of the contact positions of the at least two contacts to the corresponding contact surfaces are different.
[0072] It should be noted that the distance between the contact surface and the spring body is negatively correlated with the action force applied to the contact connected to the contact surface. That is, the smaller the distance between the contact surface and the spring body, the greater the action force applied to the contact connected to the contact surface.
[0073] For example, the connecting surface includes a first contact surface and a second contact surface; the at least two contacts include a first contact and a second contact; the first contact is connected to the first contact surface, and the second contact is connected to the second contact surface; and when the distance from the first contact surface to the spring body is smaller than the distance from the second contact surface to the spring body, the action force applied to the first contact is greater than the action force applied to the second contact.
[0074] It should be noted that the related art usually forms a surface grid on the surface of the antenna body in a laser engraving manner to increase the contact between the antenna body and the grounding spring. However, in the micro-dropping test (repeated dropping test of a mobile phone with the antenna structure of the related art at a height of 10 cm), there is still a case of wear and corrosion (which can be referred to as fretting corrosion) of the connecting surface.
[0075] Here, the mechanism of corrosion is fretting corrosion, which occurs at the contact position where the antenna body and the grounding spring contact each other and move relatively. When the antenna body and the grounding spring move relatively, adhesive wear occurs at the contact position, at which time the particles on the surface are abraded and react with the surrounding medium such as the atmosphere to generate oxides, nitrides or other compounds. Because the particles are high in hardness, the wear of the contact position is further strengthened, and thus new fretting corrosion occurs at the contact position.
[0076] Figure 3 FIG. 1 is a schematic diagram of wear of an antenna body and a grounding spring in the related art according to an example embodiment. As shown in FIG. 1, Figure 3 Figure 3 In FIG. 1, four contact positions of the antenna body 100 corresponding to the four contacts of the grounding spring 200 are covered with black powder, which is analyzed as black oxide of nickel, aluminum, copper and the like (the black oxide is the oxide of the debris generated by repeated friction of the metal of the connecting surface in the whole machine micro-dropping test). Because the four contact positions are all covered with black oxide, and the black oxide is not conductive, the four contact positions (i.e., the positions electrically connected by the grounding points) are all electrically connected to fail.
[0077] Based on this, the embodiment of the present disclosure proposes that the connection surface of the antenna body and the grounding spring has at least two contact surfaces, the at least two contacts of the grounding spring are connected to different contact surfaces, and the distances from the different contact surfaces to the spring body are different. That is, when the force acts on the antenna body and the grounding spring, the forces acting on the at least two contacts connected to different contact surfaces are inconsistent, which in turn causes the wear degrees of the contact positions of the at least two contacts and the corresponding contact surfaces to be different. In this way, the embodiment of the present disclosure can reduce the case that all contact positions are completely invalid due to wear, thereby solving the problem of poor antenna signal caused by the invalid electrical connection between the antenna body and the grounding spring, making the electrical connection between the antenna body and the grounding spring more reliable, and thereby improving the antenna performance.
[0078] Exemplarily, as shown in Figure 4 , the related art does not improve the connection surface 104, so that the four contacts of the grounding spring 200 bear consistent forces, and the embodiment of the present disclosure improves the connection surface 104, proposes to set different distances from the different contact surfaces to the spring body, and the at least two contacts are connected to different contact surfaces, which can cause different degrees of wear at the contact positions corresponding to the four contacts. Therefore, as shown in Figure 5 , after the micro-dropping test, at least one to two contact positions Figure 5 of the grounding spring 200 corresponding to the two non-oxidized contacts of the antenna body 100 Figure 5 (not shown in the figure) are relatively less worn and the grounding electrical connection continues to be effective, thereby reducing the case that all contact positions are completely invalid due to wear.
[0079] In some embodiments, as shown in Figure 1 and Figure 2 , each of the contact surfaces 101 in the antenna body 100 is connected to the contact 202;
[0080] , and / or, at least one of the contact surfaces 101 is connected to a plurality of the contacts 202.
[0081] In the embodiment of the present disclosure, the contacts connected by different contact surfaces are different, and the number of contacts connected by different contact surfaces can be the same or different. Each of the contact surfaces is connected to a contact, including: each of the contact surfaces is connected to one contact; or, each of the contact surfaces is connected to a plurality of contacts; or, a part of the contact surfaces is connected to one contact, and the other part of the contact surfaces is connected to a plurality of contacts.
[0082] It should be noted that the number of contact surfaces can be less than or equal to the number of contacts. When the number of contact surfaces is equal to the number of contacts, one contact can be connected to one contact surface. When the number of contact surfaces is less than the number of contacts, multiple contacts can be connected to one contact surface. In this way, each contact surface in the antenna body is connected to a contact.
[0083] In the embodiments of the present disclosure, each contact surface in the antenna body is connected to the contact. Different contact surfaces have different distances to the spring body. That is, the more the number of contact surfaces, the more different forces the contacts connected to different contact surfaces are subjected to, and in turn, the wear degrees of the contact positions of the connection surface are different.
[0084] For example, as shown in Figure 1 , the antenna body 100 has three contact surfaces 101, and each contact surface 101 is connected to a contact. The contacts connected to the three different contact surfaces 101 are subjected to different forces, and in turn, the wear degrees of the three contact positions of the connection surface are different.
[0085] It can be understood that since the contact positions with less wear degree can continue to maintain effective electrical connection, by arranging that all contact surfaces are connected to contacts, the situation that all contacts are caused to lose electrical connection due to wear can be minimized, so that the electrical connection between the antenna body and the grounding spring is more reliable.
[0086] In the embodiments of the present disclosure, at least one contact surface is connected to multiple contacts, which can include that one contact surface is connected to multiple contacts, or multiple contact surfaces are connected to multiple contacts. Here, the multiple contacts include two or more contacts.
[0087] For example, as shown in Figure 1 and Figure 2 , the antenna body has three contact surfaces 101, and the grounding spring has four contacts 202. The one contact surface 101 can be connected to two contacts 202 of the four contacts, and the other two contact surfaces 101 can be connected to the remaining two different contacts 202, respectively.
[0088] It can be understood that the embodiments of the present disclosure arrange that at least one contact surface is connected to multiple contacts, which can improve the connection stability between the connection surface and the multiple contacts on the grounding spring.
[0089] In some embodiments, as shown in Figure 2 , the spring body 201 is formed with a spring arm 203 inclined to the antenna body 100;
[0090] The at least two contact surfaces include a first contact surface and a second contact surface, and the distance from the first contact surface to the spring body 201 is less than the distance from the second contact surface to the spring body 201.
[0091] The contact 202 of the spring body 201 is connected to the first contact surface;
[0092] The contact 202 of the spring arm 203 is connected to the second contact surface.
[0093] In the embodiments of the present disclosure, the spring arm and the spring body are both provided with contacts. The number of contacts provided on the spring arm can be the same as or different from the number of contacts provided on the spring body.
[0094] In some embodiments, the number of contacts 202 provided on the spring body 201 is greater than the number of contacts 202 provided on the spring arm 203.
[0095] Exemplarily, as shown in Figure 2 The ground spring 200 has four contacts 202, the spring body 201 can be provided with three contacts 202, and the spring arm 203 can be provided with one contact 202.
[0096] It can be understood that the area of the surface of the spring body facing the antenna body is greater than the area of the surface of the spring arm facing the antenna body. By providing the number of contacts on the spring body greater than the number of contacts on the spring arm, the contacts of the ground spring can be more evenly distributed rather than concentrated on the spring arm. In this way, it is more conducive to connecting different contact surfaces with multiple contacts, thereby enabling more contact positions between the antenna body and the ground spring to be worn to different degrees, and thereby better reducing the situation that all electrical connections are completely disabled due to wear.
[0097] In the embodiments of the present disclosure, the spring arm is inclined to the antenna body. That is, the spring body and the spring arm are not located in the same plane. By providing the spring arm inclined to the antenna body, the connection between the antenna body and the ground spring can be more reliable.
[0098] Furthermore, in the embodiments of the present disclosure, the distance from the first contact surface to the spring plane of the first spring arm is less than the distance from the second contact surface to the spring plane, the contacts of the spring body are connected to the first contact surface, and the contacts 202 of the spring arm are connected to the second contact surface. That is, the embodiments of the present disclosure can enable the contacts of the second spring arm closer to the antenna body to be connected to the second contact surface, and the contacts of the spring body farther away from the antenna body to be connected to the first contact surface. In this way, the connection between the ground spring and the antenna body can be more stable.
[0099] In some embodiments, as shown in Figure 1 The antenna body 100 also has a connecting surface (not shown in the figure) connecting two adjacent contact surfaces 101;
[0100] The connecting surface forms the contact surface and the connecting surface by setting at least one step 102.
[0101] In the embodiments of the present disclosure, the connecting surface is a surface connecting two adjacent contact surfaces, which is different from the contact surface and does not contact the contact point.
[0102] Here, the connecting surface can be a connecting plane or a connecting curved surface. The included angle between the connecting surface and the contact surface can be a right angle, an acute angle or an obtuse angle, which is not limited in the embodiments of the present disclosure.
[0103] In the embodiments of the present disclosure, one step can form two contact surfaces. Two adjacent steps can share one contact surface.
[0104] For example, when one step is set on the connecting surface, two contact surfaces can be formed; when three steps are set on the connecting surface, three contact surfaces can be formed. In the embodiments of the present disclosure, the number of steps set on the connecting surface can be one or more.
[0105] In some embodiments, as shown in Figure 1 The antenna body 100 has a first through hole 103; the connecting surface sets a plurality of steps 102 along the edge of the first through hole 103.
[0106] That is, as shown in Figure 1 A plurality of steps 102 are set around the first through hole 103. For example, the antenna body 100 can set 3 steps to form three contact surfaces 101.
[0107] In the embodiments of the present disclosure, as shown in Figure 1 The step 102 height h plane can be a connecting surface, and the two step 102 planes with an included angle with the step 102 height h plane in the step 102 can be two adjacent contact surfaces. Here, the higher the step 102 height h, the greater the distance between the two adjacent contact surfaces 101.
[0108] It can be understood that the connecting surface can form the contact surface and the connecting surface by setting at least one step. That is, the embodiments of the present disclosure can realize different distances of different contact surfaces to the spring body by setting steps.
[0109] In some embodiments, as shown in Figure 1 The ground spring 200 has a second through hole 204; the second through hole 204 is aligned with the first through hole 103 of the antenna body 100;
[0110] The surface of the antenna body 100 in which the first through hole 103 is set and which faces the ground spring 200 constitutes the connecting surface.
[0111] In the embodiments of the present disclosure, the first through hole and the second through hole are both used for the fixing member of the electronic device to pass through, so as to fix the grounding spring sheet and the antenna body, so that the grounding spring sheet and the antenna body are stably connected.
[0112] It should be noted that the first through hole and the second through hole are aligned, including that the orthographic projection of the first through hole to the grounding spring sheet covers the second through hole.
[0113] In the embodiments of the present disclosure, the surface of the antenna body towards the grounding spring sheet, on which the first through hole is arranged, constitutes a connecting surface, that is, the connecting surface is arranged at the first through hole. By arranging the connecting surface at the first through hole, the distance from the different contact surfaces of the connecting surface to the spring body is different, so that the electrical connection reliability between the antenna body and the grounding spring sheet can be improved while the antenna body and the grounding spring sheet are fixed through the first through hole and the second through hole.
[0114] The present disclosure also provides an electronic device. As shown in Figure 1 and Figure 6 The electronic device comprises:
[0115] a conductive frame 300 and a circuit board 400;
[0116] an antenna structure as described in one or more of the above embodiments;
[0117] The conductive frame 300 is multiplexed as an antenna body 100 of the antenna structure.
[0118] The grounding spring sheet 200 of the antenna structure is connected between the circuit board 400 and the conductive frame 300.
[0119] In the embodiments of the present disclosure, the circuit board is used to carry multiple functional modules (such as an audio module or a battery module) in the electronic device and provide electrical connection for the multiple functional modules.
[0120] The conductive frame can include a conductive middle frame and a conductive bezel circumferentially surrounding the conductive middle frame. The conductive frame, which is multiplexed as the antenna body of the antenna structure, can include: the conductive middle frame is multiplexed as the antenna body; or, the conductive bezel is multiplexed as the antenna body.
[0121] The grounding spring sheet of the antenna structure is connected between the circuit board and the conductive frame. Here, the grounding spring sheet can be connected to the ground layer of the circuit board. In this way, the conductive frame can be connected to the ground layer of the circuit board through the grounding spring sheet, thereby achieving the grounding of the antenna structure, so that the antenna structure can better receive and transmit wireless signals.
[0122] It can be understood that the electronic device of the embodiment of the present disclosure comprises an antenna structure, the connecting surface of the antenna body and the grounding spring sheet in the antenna structure has at least two contact surfaces, the at least two contacts of the grounding spring sheet are connected to different contact surfaces, and the distances from the different contact surfaces to the spring body are different. That is, when the force acts on the antenna body and the grounding spring sheet, the forces acting on the at least two contacts connected to different contact surfaces are inconsistent, which further causes the wear degrees of the contact positions of the at least two contacts and the corresponding contact surfaces to be different. In this way, the embodiment of the present disclosure can reduce the case that all contact positions are caused to be completely invalid due to wear, and further can solve the problem of poor antenna signal caused by the invalid electrical connection between the antenna body and the grounding spring sheet, so that the electrical connection between the antenna body and the grounding spring sheet is more reliable, and further the antenna performance is improved.
[0123] In some embodiments, as shown in Figure 1 and Figure 6 The circuit board 400 is formed with a third through hole 500;
[0124] The third through hole 500 is aligned with the second through hole 204 of the grounding spring sheet 200 and the first through hole 103 of the antenna body 100 respectively
[0125] The electronic device further comprises:
[0126] The fixing member 600 is arranged to pass through the third through hole 500, the second through hole 204 and the first through hole 103 to fix the circuit board 400, the grounding spring sheet 200 and the conductive frame 300.
[0127] In the embodiment of the present disclosure, the third through hole, the second through hole and the first through hole are aligned. By arranging the fixing member to pass through the third through hole, the second through hole and the first through hole, the circuit board, the grounding spring sheet and the conductive frame can be fixed.
[0128] Exemplarily, the fixing member comprises a screw, and the corresponding third through hole, second through hole and third through hole can all be screw holes.
[0129] In the embodiment of the present disclosure, the electronic device further comprises a functional support. The functional support has a fourth through hole. By arranging the fixing member to pass through the fourth through hole, the fixing of the functional support, the circuit board, the grounding spring sheet and the conductive frame can also be realized.
