[0022] wherein the first direction, the second direction and the third direction are different directions.
[0023] In some embodiments, the grounding springs of the same side edge of the conductive decorative piece are two;
[0024] the free ends of the two grounding springs of the same side edge are opposite in the inclined direction.
[0025] According to a second aspect of the embodiments of the present disclosure, an electronic device is provided, comprising:
[0026] a grounding structure as mentioned in one or more of the above embodiments;
[0027] The electronic device comprises a mobile terminal.

[0029] Alternatively, the electronic device comprises a protective sleeve for protecting the mobile terminal.
[0030] The conductive decorative piece is disposed on a protective body of the protective sleeve, and the protective body is in contact with the battery cover plate when the protective sleeve is sleeved on the mobile terminal.

[0032] A third side edge of the conductive decorative piece is disposed close to a top edge of the battery cover.
[0033] In the case that the first side edge is acted by the external force, the first grounding spring of the grounding structure is elastically deformed;
[0034] In the case that the second side edge is acted by the external force, the second grounding spring of the grounding structure is elastically deformed;

[0044] And, the free end of the grounding spring sheet is connected in the groove and elastically deformed. That is, the free end has elastic deformation when connected with the conductive connecting piece. In this way, the connection between the free end and the conductive connecting piece is more reliable. Further, the free end is located in the groove, and when subjected to external force, the concave surface of the groove will hinder the free end from moving out of the groove, thereby realizing that the grounding spring sheet is firmly buckled into the groove, improving the reliability and stability of the conductive decorative piece grounding. In this way, when the antenna around the conductive decorative piece works, the influence of the conductive decorative piece on the surrounding antenna can be reduced, and the communication experience of the antenna is improved.

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0057] This disclosure provides a grounding structure. Figure 1A This is a schematic diagram of a grounding structure according to an exemplary embodiment of the present disclosure. Figure 1B This is a schematic diagram of a grounding structure according to an exemplary embodiment of the present disclosure. Figure Two .like Figure 1A and 1B As shown, the grounding structure includes:
[0058] Conductive decorative parts 100;
[0059] Grounding spring 200, having a free end 201;
[0060] The conductive connector 300 is connected to the conductive decorative component 100 and the free end 201, and has a groove 301 formed thereon;
[0061] The free end 201 is connected to the groove 301 and undergoes elastic deformation.
[0062] In this embodiment of the disclosure, the grounding structure can be a decorative element grounding structure, which is applied in scenarios where conductive decorative elements are grounded.
[0063] For example, in a scenario where a grounding structure is set on a mobile terminal and used to decorate the camera module of the mobile terminal, the grounding structure can reduce the grounding deviation of the conductive decorative part when an external force is applied to the mobile terminal, allowing the conductive decorative part to be grounded more stably. This reduces the impact of the conductive decorative part on surrounding antennas, improving the communication experience of the mobile terminal.
[0064] In this embodiment of the disclosure, the conductive decorative element can be used not only to decorate the camera module of a mobile terminal, but also to be installed in the protective body of a protective case in an electronic device.
[0065] Here, the conductive decorative part can be a metal decorative part or a conductive plastic decorative part.
[0066] It should be noted that the conductive decorative element may have a ring-shaped structure. In some embodiments, the conductive decorative element is circular; in other embodiments, the conductive decorative element is square.
[0067] In the embodiments of the present disclosure, as shown in Figure 1A and Figure 2 The grounding spring 200 has a free end 201. In some embodiments, the grounding spring 200 also has a fixed end 202. When the grounding spring is subjected to an external force, the free end 201 can elastically deform relative to the fixed end 202.
[0068] As shown in Figure 2 The free end 201 is inclined relative to the fixed end 202. When the free end 201 is subjected to an external force E, the free end 201 elastically deforms. When the external force E is removed, the free end 201 generates a restoring force F. Here, the directions of the external force E and the restoring force F are opposite.
[0069] It should be noted that the grounding spring is connected to the ground, and can return the signal sensed by the conductive trim to the ground when the antenna is working, thereby reducing the influence on the antenna around the conductive trim.
[0070] In the embodiments of the present disclosure, the conductive connecting piece is connected to the conductive trim and the free end, that is, the conductive trim is directly grounded through the conductive connecting piece and the grounding spring, and does not need to be connected through additional devices.
[0071] Exemplarily, the conductive connecting piece can include a conductive connecting column, which can be a square connecting column or a cylindrical connecting column, and the embodiments of the present disclosure do not limit this.
[0072] Here, the conductive connecting piece can have a first connecting part and a second connecting part. The first connecting part can be fixedly connected to the conductive trim, and the second connecting part can be elastically connected to the grounding spring. That is, the free end and the conductive connecting piece are elastically deformed when they are connected. In this way, the free end and the conductive connecting piece can be more reliably connected.
[0073] It should be noted that the fixed connection mode of the first connecting part and the conductive trim includes riveting or screw connection, and the embodiments of the present disclosure do not limit this.
[0074] In the embodiments of the present disclosure, the first connecting part and the second connecting part can be arranged at different positions of the conductive connecting piece.
[0075] In some embodiments, the first connecting part can be arranged at the top end of the conductive connecting piece, and the second connecting part can be arranged at the bottom end of the conductive connecting piece. In other embodiments, the first connecting part can be arranged at the top end of the conductive connecting piece, and the second connecting part can be arranged at the side of the conductive connecting piece.
[0076] In the embodiments of the present disclosure, a groove can be formed in the second connecting part of the conductive connecting piece, and the free end is connected in the groove. Here, the groove can be recessed in the direction away from the grounding spring.
[0077] It should be noted that the second connecting portion can be a connecting portion facing the free end, having at least one end face. That is, in some embodiments, the conductive connecting piece has at least one end face facing the free end; the at least one end face is recessed to form a groove in a direction away from the grounding spring.
[0078] In the embodiments of the present disclosure, the at least one end face can be processed to form a groove by laser technology.
[0079] Here, when the end face facing the free end is one, the one end face can be recessed to form the groove in a direction away from the grounding spring; when the end face facing the free end is at least two, the at least two end faces can be recessed to form the groove in a direction away from the grounding spring.
[0080] It can be understood that by recessing the at least one end face to form the groove, the setting of the groove can be more flexible.
[0081] In the embodiments of the present disclosure, the free end is connected in the groove, that is, the free end is connected with the recessed surface (such as a recessed curved surface or a recessed bent straight surface) of the groove. In this way, when the electronic device with the grounding structure is subjected to an external force, the recessed surface of the groove will hinder the movement of the free end out of the groove, and thus the grounding spring can be firmly buckled into the groove, thereby improving the reliability and stability of the grounding of the conductive decorative piece.
[0082] It should be noted that the groove includes a flat surface and a recessed arc surface, and the recessed arc surface is recessed in a direction away from the grounding spring.
[0083] In some embodiments, the free end is connected to the recessed arc surface of the groove.
[0084] In the embodiments of the present disclosure, the free end can be connected to any position of the recessed arc surface of the groove. Here, the groove includes a groove bottom with a recessed arc surface and a groove wall with a recessed arc surface; the free end can be connected to the groove bottom and / or the groove wall.
[0085] It should be noted that the free end is connected to the groove bottom, and the recessed arc surface of the groove bottom will hinder the movement of the free end out of the groove when subjected to an external force; the free end is connected to the groove wall, and the recessed arc surface of the groove wall will hinder the movement of the free end out of the groove when subjected to an external force.
[0086] Exemplarily, Figure 3 is a schematic diagram of an existing grounding structure according to an exemplary embodiment. Figure 4 is a schematic diagram of an existing grounding structure according to an exemplary embodiment. Figure Two As shown in Figure 3 , the conductive spring 11 connects the conductive decorative piece 12 and the steel sheet 13 by spot welding. As shown in Figure 4As shown, the conductive foam 14 connects the conductive decoration 12 and the steel sheet 13.
[0087] As can be seen, the existing grounding structure either needs a steel sheet adapter, increasing the cost and thickness, or has poor stability and will cause relative sliding and poor grounding under external force impact.
[0088] Based on this, the conductive connector is connected to the free end of the conductive decoration and the grounding spring in the embodiments of the present disclosure, so that the conductive decoration can be directly grounded through the grounding spring and the conductive connector, without the need for device adapter, which not only reduces the cost of auxiliary materials but also reduces the thickness of the grounding structure.
[0089] In addition, the free end of the grounding spring is connected in the groove and elastically deformed in the embodiments of the present disclosure. That is, the free end has elastic deformation when connected with the conductive connector. In this way, the connection between the free end and the conductive connector can be more reliable. Further, the free end is located in the groove, and when subjected to external force, the concave surface of the groove will hinder the movement of the free end out of the groove, thereby realizing that the grounding spring is firmly buckled into the groove, improving the reliability and stability of the grounding of the conductive decoration. In this way, when the antenna around the conductive decoration works, the influence of the conductive decoration on the surrounding antenna can be reduced, improving the communication experience of the antenna.
[0090] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 , the grounding spring 200 is a plurality of; the plurality of grounding springs 200 are connected to different side edge positions of the conductive decoration 100 or different positions of the same side edge of the conductive decoration 100.
[0091] Among them, in the case that the electronic device with the grounding structure is subjected to external force, at least part of the grounding springs 200 in the plurality of grounding springs 200 elastically deforms.
[0092] In the embodiments of the present disclosure, the conductive decoration can be a ring structure or a sheet structure.
[0093] Here, in the case that the conductive decoration is a ring structure, a plurality of grounding springs can be connected to different outer edge positions of the conductive decoration; in the case that the conductive decoration is a sheet structure, a plurality of grounding springs can be connected to different side edge positions of the conductive decoration.
[0094] In the embodiments of the present disclosure, the plurality of grounding springs connected to different edge positions of the conductive decoration can include: the plurality of grounding springs connected to different side edges of the conductive decoration. In this way, the plurality of grounding springs can resist impact forces in different directions.
[0095] Here, the multiple grounding springs are connected to different positions of the same edge of the conductive decorative piece, and when an impact force is generated on the same edge under the action of an external force, the strength against the impact force can be improved.
[0096] At least part of the multiple grounding springs can be elastically deformed, which can include that all the grounding springs are elastically deformed, or part of the grounding springs are elastically deformed. That is, there is always a grounding spring elastically deformed to resist the impact force under the action of an external force.
[0097] It should be noted that after the free end of the grounding spring is elastically deformed under the action of an external force, if the external force is removed, the rebound force generated by the free end can make the free end return to the original position. In this way, the embodiment of the present disclosure sets that at least part of the grounding springs are elastically deformed under the action of an external force, so that the rebound force generated by the grounding springs when the external force is removed can resist the impact force, thereby further improving the connection reliability and stability between the grounding springs and the conductive connector.
[0098] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 , the conductive decorative piece has a first side edge (not shown in the figure), a second side edge (not shown in the figure) disposed opposite to the first side edge, and a third side edge (not shown in the figure) connected to the first side edge and the second side edge;
[0099] The multiple grounding springs 200 include:
[0100] The first grounding spring 203 is disposed on the first side edge; and / or,
[0101] The second grounding spring 204 is disposed on the second side edge; and / or,
[0102] The third grounding spring 205 is disposed on the third side edge.
[0103] In the embodiment of the present disclosure, as shown in Figure 5 , when the first side edge of the conductive decorative piece 100 is disposed close to the first side edge 400 of the battery cover of the electronic device, that is, the first grounding spring 203 is disposed close to the first side edge 400, the first grounding spring 203 can resist the first external force acting on the first side edge 400 of the battery cover;
[0104] When the second side edge of the conductive decorative piece 100 is disposed close to the second side edge 500 of the battery cover, that is, the second grounding spring 204 is disposed close to the second side edge 500, the second grounding spring 204 can resist the second external force acting on the second side edge 500 of the battery cover;
[0105] When the third side edge of the conductive decoration piece 100 is arranged close to the top edge 600 of the battery cover, i.e., the third grounding spring is arranged close to the top edge 600, the third grounding spring 205 can resist the third external force acting on the top edge 600 of the battery cover.
[0106] It should be noted that the first grounding spring can be multiple to improve the resistance strength of the first external force. Here, the free ends of a part of the first grounding springs and the free ends of another part of the first grounding springs are opposite in the inclination direction to realize the resistance to the first external force in the opposite direction.
[0107] The second grounding spring can be multiple to improve the resistance strength of the second external force. Here, the free ends of a part of the second grounding springs and the free ends of another part of the second grounding springs are opposite in the inclination direction to realize the resistance to the second external force in the opposite direction.
[0108] The third grounding spring can be multiple to improve the resistance strength of the third external force. Here, the free ends of a part of the third grounding springs and the free ends of another part of the third grounding springs are opposite in the inclination direction to realize the resistance to the external force in the opposite direction.
[0109] It can be understood that the three grounding springs are arranged at three different side edges of the conductive decoration piece, so that the three grounding springs can resist impact forces in different directions, and the connection reliability and stability between the grounding spring and the conductive connector can be further improved.
[0110] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 , the first grounding spring 203 elastically deforms under the action of the external force in the first direction;
[0111] the second grounding spring 204 elastically deforms under the action of the external force in the second direction;
[0112] the third grounding spring 205 elastically deforms under the action of the external force in the third direction;
[0113] wherein the first direction, the second direction and the third direction are different directions.
[0114] In the embodiments of the present disclosure, the first direction and the second direction can be the same direction or opposite directions.
[0115] Exemplarily, as shown in Figure 7 , the first direction is the A direction, the second direction is the B direction, or the first direction and the second direction are both the A direction.
[0116] In the embodiments of the present disclosure, the third direction is perpendicular to the first direction or the second direction.
[0117] Exemplarily, as shown in Figure 7 , the first direction is the A direction, the second direction is the B direction, the third direction C is perpendicular to the first direction A, and the third direction C is perpendicular to the second direction B.
[0118] It can be understood that, under the action of the external force in the first direction, the impact force can be resisted by the first grounding spring, under the action of the external force in the second direction, the impact force can be resisted by the second grounding spring, and under the action of the external force in the third direction, the impact force can be resisted by the third grounding spring, that is, the embodiments of the present disclosure can flexibly resist the impact force from different three directions.
[0119] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 7 , the grounding springs 200 of the same side edge of the conductive decorative part 100 are two;
[0120] The inclination directions of the free ends of the two grounding springs 200 of the same side edge are opposite.
[0121] In the embodiments of the present disclosure, the first grounding spring 203 can be two, the two first grounding springs 203 are arranged at different positions of the first side edge, and the inclination directions of the free ends 201 of the two first grounding springs 203 are opposite.
[0122] In this way, by arranging the inclination directions of the free ends of the two first grounding springs on the first side edge to be opposite, the impact force in the opposite direction received by the first side edge can be resisted.
[0123] In the embodiments of the present disclosure, the second grounding spring 204 can be two, the two second grounding springs 204 are arranged at different positions of the second side edge, and the inclination directions of the free ends 201 of the two second grounding springs 204 are opposite.
[0124] In this way, by arranging the inclination directions of the free ends of the two second grounding springs on the second side edge to be opposite, the impact force in the opposite direction received by the second side edge can be resisted.
[0125] In the embodiments of the present disclosure, the third grounding spring 205 can be two, the two third grounding springs 205 are arranged at different positions of the third side edge, and the inclination directions of the free ends 201 of the two third grounding springs 205 are opposite.
[0126] Exemplarily, when one corner (i.e., a first connection position between the top edge 600 and the first side edge 400) of the battery cover top edge 600 is subjected to an external force and the other corner (i.e., a second connection position between the top edge 600 and the second side edge 500) is subjected to an external force, the free ends 201 of the two third grounding springs 205 are elastically deformed to resist the impact force from the opposite direction.
[0127] It can be understood that, by setting the opposite directions of the inclined directions of the free ends of the two grounding springs located at the same side edge according to the embodiments of the present disclosure, the impact force from the opposite direction on the same side edge can be resisted.
[0128] The embodiments of the present disclosure further provide an electronic device, which comprises:
[0129] The grounding structure according to one or more of the above embodiments;
[0130] The electronic device comprises a mobile terminal.
[0131] The conductive decoration part of the grounding structure is arranged on the battery cover plate of the mobile terminal and is used for decorating the camera module of the mobile terminal.
[0132] Alternatively, the electronic device comprises a protective sleeve for protecting the mobile terminal.
[0133] The conductive decoration part is arranged on the protective body of the protective sleeve, and the protective body is in contact with the battery cover plate when the protective sleeve is sleeved on the mobile terminal.

[0137] In the embodiments of the present disclosure, when the grounding structure is arranged on the mobile terminal, the grounding spring is connected to the ground of the mobile terminal. In some embodiments, the grounding spring of the grounding structure has a fixed end fixed relative to the free end.
[0138] The fixed end is connected to the ground layer of the circuit board in the mobile terminal or is connected to the middle frame of the mobile terminal.

[0140] In the embodiments of the present disclosure, the electronic device can further include a protective sleeve sleeved on the mobile terminal. The conductive decoration piece can be a metal sheet, which can be used for decorating the protective sleeve or can be reused as a support function of the protective sleeve.
[0141] That is, the embodiments of the present disclosure can also be applied to the protective sleeve scenario, which can reduce the influence of the protective sleeve on the antenna when the protective sleeve is sleeved on the mobile terminal and the antenna in the mobile terminal is working.
[0142] Illustratively, the protective sleeve has a metal support that can be used to support the mobile terminal sleeved on the protective sleeve and also can decorate the protective sleeve.
[0143] It can be understood that the electronic device of the embodiments of the present disclosure includes a grounding structure, which can be directly grounded through the grounding spring and the conductive connecting piece, so that the device adapter is not needed, which not only reduces the cost of auxiliary materials but also reduces the thickness of the electronic device. Moreover, the free end of the present disclosure is located in the groove, and when subjected to external force, the recessed surface of the groove will hinder the movement of the free end outside the groove, thereby achieving that the grounding spring is firmly buckled into the groove, improving the reliability and stability of the grounding of the conductive decoration piece. In this way, when the antenna around the conductive decoration piece is working, the influence of the conductive decoration piece on the surrounding antenna can be reduced, and the communication experience of the mobile terminal is improved.

[0151] In the embodiments of the present disclosure, the first side edge of the conductive decorative piece is arranged close to the first side of the battery cover, so that when the external force acts on the first side edge, the free end of the first grounding spring elastically deforms. Here, the free end of the first grounding spring can be inclined towards the first connection position, and can also be inclined away from the first connection position.
[0152] It should be noted that the first grounding spring can be two, and if two first grounding springs are arranged at the first side edge, the free end of one of the two first grounding springs can be inclined towards the first connection position, and the free end of the other first grounding spring can be inclined away from the first connection position.
[0153] In the embodiments of the present disclosure, the second side edge of the conductive decorative piece is arranged close to the second side of the battery cover, so that when the external force acts on the second side edge, the free end of the second grounding spring elastically deforms. Here, the free end of the second grounding spring can be inclined towards the second connection position, and can also be inclined away from the second connection position.
[0154] It should be noted that the second grounding spring can be two, and if two second grounding springs are arranged at the second side edge, the free end of one of the two second grounding springs can be inclined towards the second connection position, and the free end of the other second grounding spring can be inclined away from the second connection position.
[0155] In the embodiments of the present disclosure, the third side edge of the conductive decorative piece is arranged close to the top edge of the battery cover, so that when the external force acts on the top edge, the free end of the third grounding spring elastically deforms. Here, the free end of the third grounding spring can be inclined towards the second connection position, and can also be inclined towards the first connection position.
[0156] It should be noted that the third grounding spring can be two, and if two third grounding springs are arranged at the third side edge, the free end of one of the two third grounding springs can be inclined towards the second connection position, and the free end of the other third grounding spring can be inclined towards the first connection position.
[0157] It can be understood that when the external force acts on the first side, the second side and / or the top edge of the battery cover, the grounding spring will elastically deform, thereby enabling the grounding spring to resist the external force when the external force acts on different edges of the battery cover.
[0158] In some embodiments, as Figure 5 , Figure 6 and Figure 7As shown,
[0159] The free end 201 of the first grounding spring 203 and the free end 201 of one of the third grounding springs 205 are both inclined away from a first connection position G between the first side edge 400 and the top edge 600.
[0160] The free end 201 of the second grounding spring 204 and the free end 201 of the other third grounding spring 205 are both inclined away from a second connection position H between the second side edge 500 and the top edge 600.
[0161] In the case where the external force acts on the first connection position G, the first grounding spring 203 and one of the third grounding springs 205 both elastically deform.
[0162] In the case where the external force acts on the second connection position H, the second grounding spring 204 and the other third grounding spring 205 both elastically deform.
[0163] In the embodiments of the present disclosure, the first connection position and the second connection position are arranged at opposite ends of the top edge. When the free end of one of the third grounding springs is inclined away from the first connection position, it can be understood that the free end of one of the third grounding springs is inclined toward the second connection position.
[0164] Similarly, when the free end of the other third grounding spring is inclined away from the second connection position, it can be understood that the free end of the other third grounding spring is inclined toward the first connection position.
[0165] In the embodiments of the present disclosure, in the case where the external force acts on the first connection position, i.e. Figure 5 the upper left corner of the middle part is subjected to the external force, the first grounding spring and one of the third grounding springs both elastically deform.
[0166] It should be noted that, as shown, Figure 7 the external force acting on the first connection position G (the upper left corner of the battery cover) can be divided into an A-direction force and a B-direction force. Since the A-direction force causes the first elastic member to elastically deform, when the A-direction force is removed, a C-direction springback force is generated. Since the B-direction force causes one of the third elastic members to elastically deform, when the B-direction force is removed, a D-direction springback force is generated.
[0167] It can be seen that the external force on the upper left corner can be respectively offset by the rebound force in the C direction and the rebound force in the D direction, thereby realizing that the first grounding spring and one third grounding spring can resist the external force acting on the first connection position. Similarly, the second grounding spring and another third grounding spring can also resist the external force acting on the second connection position H (the upper right corner of the battery cover).
