The antenna spring provided in the embodiment of the application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 9, an antenna spring is disclosed in the embodiment of the present application, and the disclosed antenna spring includes a spring base 100 and a spring body 200.

The spring base 100 is a base of the spring body 200, and during the installation of the antenna spring, the spring base 100 is generally fixed on a circuit board (e.g., a motherboard) in an electronic device (e.g., a mobile phone) through a chip mounting process. In this embodiment, the spring base 100 includes a first side wall 110, a second side wall 120, a third side wall 130 and a fourth side wall 140 that are connected end to end in sequence, where the first side wall 110, the second side wall 120, the third side wall 130 and the fourth side wall 140 enclose an accommodating space 101, the first side wall 110 and the third side wall 130 are oppositely disposed, and the second side wall 120 and the fourth side wall 140 are oppositely disposed. That is, the first, second, third and

fourth sidewalls

110, 120, 130 and 140 form a cylindrical structural member.

The spring body 200 is a portion of the antenna spring for electrically connecting with a metal region (e.g., a metal middle frame) of a housing of the electronic device. The elastic piece body 200 is bent to form an elastic piece force arm 210, an elastic contact part 220 and a supporting part 230 which are sequentially connected, one end of the elastic piece force arm 210 is connected with the top end of the second side wall 120, and the other end of the elastic piece force arm 210 is connected with the elastic contact part 220. The supporting portion 230 extends into the accommodating space 101, the first side wall 110 is provided with a first hanging hole 111, the third side wall 130 is provided with a second hanging hole 131, the first hanging hole 111 and the second hanging hole 131 are oppositely arranged, two ends of the supporting portion 230 are respectively located in the first hanging hole 111 and the second hanging hole 131, and the supporting portion 230 is in elastic contact with the first side wall 110 and the third side wall 130.

In a specific operation process, the elastic contact portion 220 is pressed by the metal area of the electronic device housing, so as to drive the elastic force arm 210 to rotate, and the elastic force arm 210 drives the elastic contact portion 220 and the support portion 230 to rotate, so that the support portion 230 contacts with the edges of the first hooking hole 111 and the second hooking hole 131, and a loop is formed between the metal area of the electronic device housing and the antenna elastic sheet.

In this embodiment, first lateral wall 110, second lateral wall 120, third lateral wall 130 and fourth lateral wall 140 form the tube-shape structure, the part of shell fragment body 200 is hidden in the tube-shape structure, thereby make shell fragment body 200 be difficult to with electronic equipment's other functional device take place to scratch, simultaneously, shell fragment base 100 is by four lateral walls surrounding city tube-shape structure, and then can improve antenna shell fragment's bulk strength, this certainly can improve antenna's anti deformation performance, thereby make antenna shell fragment be difficult to take place to warp, and then effectively prevent antenna shell fragment damage, can antenna shell fragment's performance.

Meanwhile, the elastic sheet base 100 is a cylindrical structural member, so that the contact area between the elastic sheet base 100 and the circuit board of the electronic device is large, and the elastic sheet base 100 is more stably installed.

In addition, the edges of the first hooking hole 111 and the second hooking hole 131 can limit the supporting portion 230, and at this time, the elastic force arm 210 can be prevented from being excessively compressed, so that the elastic force arm 210 is excessively deformed and damaged.

In addition, the spring plate base 100 is a cylindrical structural member, the end face of one end of the cylindrical structural member is in contact with the circuit board of the electronic device, the contact area between the end face of the cylindrical structural member and the circuit board of the electronic device is large, and the spring plate base 100 is installed more stably, so that when the height of the antenna spring plate is increased, the area of the end face of the spring plate base 100 can not be changed, and the installation space of the circuit board of the electronic device occupied by the antenna spring plate is small.

In order to better protect the elastic force arm 210, the antenna elastic sheet disclosed in the embodiments of the present application may further include a protection wall, where the protection wall covers the elastic force arm 210, so as to protect the elastic force arm 210 and further prevent the elastic force arm 210 from being scratched and rubbed to deform.

The elastic force arm 210 can cooperate with the first side wall 110 and the third side wall 130 to form better protection, and deformation of the elastic force arm 210 can be further relieved. Specifically, the protection wall may be connected to the top end of the first side wall 110, the protection wall 150 may form a protection space with the first side wall 110 and the third side wall 130, and the elastic arm 210 may be located in the protection space. Of course, the protective wall 150 may be connected to both the top end of the first side wall 110 and the top end of the third side wall 130, which can certainly improve the overall strength of the antenna dome.

In order to facilitate the forming, in another alternative, the protective wall 150 and the first side wall 110 may be integrally formed with a bending structural member, so that the structure of the antenna spring may be simplified, and the overall structural strength of the antenna spring may be improved.

In the above embodiment, when the elastic contact portion 220 is compressed, the elastic contact portion may shake, so that the elastic force arm 210 slides, and the contact between the supporting portion 230 and the first and

second side walls

110 and 120 is unstable, which results in poor loop consistency of the antenna elastic sheet.

Based on this, in another alternative embodiment, a side of the support portion 230 facing away from the elastic contact portion 220 may be extended with a sliding portion 231, and a side of the sliding portion 231 facing away from the fourth sidewall 140 is bent.

The edge of the first hooking hole 111 may extend toward the inside of the accommodating space 101 to form a first protrusion 112, the edge of the second hooking hole 131 may extend toward the inside of the accommodating space 101 to form a second protrusion 132, the first protrusion 112 may form a sliding space with the second protrusion 132, and the sliding portion 231 may be slidably engaged with the sliding space.

In this solution, the sliding portion 231 is slidably connected with the sliding space, so that the moving direction of the sliding portion 231 can be limited, and then the moving direction of the supporting portion 230 can be limited, so as to prevent the supporting portion 230 from shaking, and further the supporting portion 230 is tightly contacted with the first side wall 110 and the second side wall 120, so that the loop consistency of the antenna elastic sheet can be improved.

To further prevent the spring force arm 210 from being excessively compressed, in another alternative embodiment, at least one of the first protrusion 112 and the second protrusion 132 may be in a limit fit with the sliding portion 231 in the sliding direction of the sliding portion 231. In this solution, the sliding portion 231 is in limit fit with the first protrusion 112 and/or the second protrusion 132, so as to limit the sliding stroke of the sliding portion 231, and further limit the rotation stroke of the elastic force arm 210, when the elastic force arm 210 rotates to the maximum stroke, that is, under the condition that the sliding portion 231 is in limit fit with the first protrusion 112 or the second protrusion 132, the elastic force arm 210 is difficult to move, so as to prevent the elastic force arm 210 from being damaged.

Optionally, a limiting protrusion may be disposed on the first protrusion 112 and/or the second protrusion 132, and the limiting protrusion is in limiting engagement with the sliding portion 231 in the sliding direction of the sliding portion 231. Alternatively, the sliding portion 231 has a tapered structure in a direction away from the supporting portion 230, that is, an area of a cross section of an end of the sliding portion 231 connected to the supporting portion 230 is larger, and an area of a cross section of an end of the sliding portion 231 away from the supporting portion 230 is smaller. The sliding space is tapered in a direction in which the second sidewall 120 points toward the fourth sidewall 140. At this time, when the sliding portion 231 slides to the limit position during the sliding along the sliding space, the sliding portion 231 is difficult to move, and the elastic force arm 210 is difficult to rotate.

In the above embodiment, after the supporting portion 230 contacts the first protrusion 112 and the second protrusion 132, a line contact is formed, in the above scheme, the supporting portion 230 is easy to be unstable in contact when sliding, resulting in tilting of the end of the supporting portion 230, so that the loop consistency of the antenna dome is poor. Based on this, in another alternative embodiment, the first protrusion 112 and the second protrusion 132 are disposed obliquely in a direction away from the top end of the first sidewall 110. In this solution, the contact positions of the supporting portion 230 and the first protrusion 112 and the second protrusion 132 form point contact, and the contact surface is smaller when the supporting portion 230 slides, so that the influence on the uniformity of the loop is smaller, and the uniformity of the loop of the antenna dome is improved.

In the above embodiment, the antenna elastic sheet may be provided with a die connecting port 102, where the die connecting port 102 is a position where the antenna elastic sheet is connected with a die in the manufacturing process, and the die connecting port 102 is easy to generate a sharp, so as to affect the mounting of the antenna elastic sheet. For this purpose, in another alternative embodiment, the spring plate base 100 may be a cylindrical structural member, the end surface of the bottom end of the cylindrical structural member may be a welding surface, and the die connecting port 102 may be located on the side wall of the cylindrical structural member and avoid the welding surface. In this scheme, the die material connecting port 102 avoids the welding surface of the antenna shrapnel, so that the batch edge generated by the die material connecting port 102 is not easy to influence the mounting of the antenna when the antenna shrapnel is mounted.

In the above embodiment, the extending direction of the first hooking hole 111 may be a horizontal direction, and at this time, the supporting portion 230 receives a larger driving force when the supporting portion 230 slides, so that the supporting portion 230 is easy to deform. For this, in another alternative embodiment, the distance between the edge of the first hooking hole 111 and the top end of the first sidewall 110 may be gradually increased in the direction of the fourth sidewall 140 to the second sidewall 120, that is, the first hooking hole 111 is disposed to be inclined. In this embodiment, the angle between the edge of the first hooking hole 111 and the supporting portion 230 is reduced, so that the acting force of the supporting portion 230 on the edge of the first hooking hole 111 is reduced during the movement, and the supporting portion 230 can be prevented from being deformed.

Further, in the direction from the fourth side wall 140 to the second side wall 120, the distance between the edge of the second hooking hole 131 and the top end of the third side wall 130 may be gradually increased, that is, the second hooking hole 131 is inclined. The effect of this scheme is the same as the above scheme, and will not be described here again.

In the process of manufacturing the spring base 100, a laser cutting machine or a punching machine is required to cut or punch the base material, and then the cut or punched base material is bent to form the spring base 100. After the elastic sheet base 100 is bent and formed, the elastic sheet base 100 has a butt joint gap, and the elastic sheet base 100 is easy to deform at the butt joint gap. To this end, in an alternative embodiment, the fourth sidewall 140 may include a first sub-wall 141 and a second sub-wall 142, the first sub-wall 141 may be connected to the first sidewall 110, and the second sub-wall 142 may be connected to the third sidewall 130. An edge of a side of the first sub-wall 141 facing away from the first side wall 110 may be provided with a connection recess 1411. An edge of a side of the second sub-wall 142 facing away from the third sidewall 130 may be provided with a connection protrusion 1421, and the connection protrusion 1421 may be located in the connection recess 1411 and engaged with the connection recess 1411. In this solution, the butt joint gap of the antenna is located between the first sub-wall 141 and the second sub-wall 142, at this time, the first sub-wall 141 and the second sub-wall 142 are clamped by the connecting concave portion 1411 and the connecting convex portion 1421, so that the tensile and compressive properties between the first sub-wall 141 and the second sub-wall 142 are improved, the overall rigidity of the elastic sheet base 100 is further improved, and the elastic sheet base 100 can be further effectively prevented from being deformed.

In the above embodiment, the elastic body 200 may further include a connecting portion 240, the elastic arm 210 and the elastic contact portion 220 may be connected by the connecting portion 240, and an included angle between the connecting portion 240 and the second side wall 120 may be smaller than 90 °. In this embodiment, the included angle between the connecting portion 240 and the second side wall 120 is smaller, and the rotation range of the elastic force arm 210 is smaller, so that the elastic force arm 210 is easy to deform. To this end, in an alternative embodiment, the angle between the engagement portion 240 and the second side wall 120 may be between 90 ° and 180 °. In this embodiment, the included angle between the engagement portion 240 and the second side wall 120 is larger, and the elastic force arm 210 has a larger rotation range, so the elastic force arm 210 is not easy to deform.

In order to facilitate manufacturing, in another alternative scheme, the antenna elastic sheet can be an integral structural member, and the scheme can improve the overall structural strength of the antenna elastic sheet, so as to further improve the usability of the antenna elastic sheet. Specifically, the antenna spring plate may be formed by bending a single piece of metal sheet (e.g., steel sheet). The antenna spring plate can be cut firstly, so that the outline structure of the antenna spring plate is formed, and the antenna spring plate is formed by bending.
