Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the first embodiment:

referring to fig. 1-14, the present invention provides an antenna with a spring plate and a device including the same, the device further includes an injection molding member and a PCB board, wherein the antenna with a spring plate and the injection molding member 100 are integrally formed, and the injection molding member 100 includes a plurality of movable grooves 101.

The choice of plastic part depends mainly on the type of plastic (thermoplastic or thermosetting), the starting morphology and the shape and dimensions of the product. Injection-molded parts are generally produced by molding, transfer molding or injection molding. Lamination, molding and thermoforming are the shaping of plastics in a plane. The method can be used for rubber processing. Further, casting using a liquid monomer or a polymer as a raw material may be mentioned. Among these methods, extrusion and injection molding are the most used and the most basic molding method.

The antenna with the shrapnel comprises an antenna body 200, a plurality of shrapnels 300 and fixing wings 400 fixed on the side edges of the shrapnels 300, wherein the number of the shrapnels 300 is the same as that of the movable grooves 101. The elastic sheet 300 is arranged in the movable slot 101, a pivoting piece 301 connected with the antenna body 200 is arranged at a first end of the elastic sheet 300, a second end of the elastic sheet 300 is bent towards the first end of the elastic sheet 300 to form an elastic foot 302, and the fixed wing 400 is embedded in the side wall of the movable slot 101.

The injection molding 100 is used as a carrier device of the antenna body 200, and is used to carry the antenna body 200 to move under the driving of an external device, and to make the antenna body 200 and a specific position on the PCB 500 collide with each other to be electrically connected, wherein the collision action is that the elastic sheet 300 on the antenna body 200 collides with the PCB.

Referring to fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, and fig. 7, which disclose structural features of the antenna with spring plate in the present application, wherein the antenna body 200 is connected to a plurality of spring plates 300 through a plurality of pivoting pieces 301, and the antenna body 200, the pivoting pieces 301, and the spring plates 300 are made of the same conductive material or made of a metal material such as a steel plate, a copper plate, an alloy plate, etc.

The antenna body 200, the pivoting piece 301 and the elastic sheet 300 are obtained by using the same plate for laser cutting and sheet metal bending, the pivoting piece 301 is used as a bending structure between the antenna body 200 and the elastic sheet 300, and the antenna body 200, the pivoting piece 301 and the elastic sheet 300 are made of the same plate, so that the whole structure is integrally formed, when a mature processing technology is obtained, one plate is easily and quickly processed to produce a structure formed by combining the antenna body 200, the pivoting piece 301 and the elastic sheet 300, of course, other methods such as welding, bolt connection, rivet connection and the like can be adopted, wherein the bolt connection is convenient to disassemble and assemble and is low in cost, but the situation of looseness is easy to occur under the condition of alternating load, the rivet connection and welding can both have excellent connection strength and are not easy to loosen, but the rivet connection also needs high hole forming precision requirements on two connecting bodies, and the bolt connection and the rivet connection can be abrupt at the connection position and occupy certain space resources, and therefore, in the structure of the integrally formed technology, the antenna body 200, the pivoting piece 301 and the elastic sheet 300 can be fixed together by preferentially adopting a welding mode.

Since the spring 300 placed in the movable groove 101 actually contacts the PCB 500 with the spring leg 302, as shown in fig. 10, a portion of the spring leg 302 is to extend out of the movable groove 101 for directly abutting against the PCB 500, wherein the second end of the spring 300 can directly serve as a "spring leg" to abut against the PCB 500 for electrical connection, but as shown in fig. 10, the first end of the spring 300 is directly embedded in the injection molded part 100, and if the second end of the spring 300 directly abuts against the PCB 500, the second end of the spring 300 needs to face downward and extend out of the movable groove 101, but since the deformation capability is attenuated to some extent, and there is not a small distance from the second end of the spring 300 to the end embedded in the injection molded part 100, the deformation capability is not very strong, and a long-term use may cause the deformation capability of the spring 300 to be weakened or even fail to normally complete the work of abutting against the PCB.

Therefore, in this example, the spring leg 302 formed by bending the second end of the elastic sheet 300 has a small resilient distance and a strong deformation capability, wherein the bending part between the spring leg 302 and the elastic sheet 300 provides a strong deformation capability, and in order to ensure that the elastic sheet 300 does not have deformation actions such as deviation when the spring leg 302 collides with the PCB 500, the fixed wing 400 extends from the side edge of the elastic sheet 300, and the fixed wing 400 directly extends into the injection molding member 100, so as to stably support the elastic sheet 300 in the movable groove 101.

In example two:

the utility model provides a take antenna of shell fragment and a device including this antenna of taking shell fragment, the device still includes injection molding and PCB board, wherein, this take antenna of shell fragment and 100 integrated into one piece of injection molding, injection molding 100 includes a plurality of movable grooves 101, and this take antenna of shell fragment includes antenna body 200, a plurality of shell fragment 300 and is fixed in stationary vane 400 on the side of shell fragment 300, and the quantity of shell fragment 300 is the same with the quantity of movable groove 101. The elastic sheet 300 is arranged in the movable slot 101, a pivoting piece 301 connected with the antenna body 200 is arranged at a first end of the elastic sheet 300, a second end of the elastic sheet 300 is bent towards the first end of the elastic sheet 300 to form an elastic foot 302, and the fixed wing 400 is embedded in the side wall of the movable slot 101.

The elastic leg 302 includes a bending portion 3021 and a first abutting portion 3022, a first end of the bending portion 3021 is connected to a first end of the elastic sheet 300, and a second end of the bending portion 3021 is connected to the first abutting portion 3022.

Referring to fig. 5 and 6, the first interference portion 3022 is disposed outside the movable slot 101, the bent portion 3021 is substantially an extension of the second end of the spring 300, and a radius is formed between the bent portions, and the first interference portion 3022 is also a radius structure formed by bending, so that the bent portion 3021 forms a sheet body with rounded upper and lower ends.

Referring to fig. 10 and 13, it is disclosed that when the injection molded part 100 and the PCB 500 are in contact with each other, the first interference portion 3022 extending out of the movable groove 101 interferes with the PCB 500, wherein components such as a conductive sheet and the like capable of establishing an electrical connection with the first interference portion 3022 after contact are pre-disposed on the PCB 500, and the conductive sheet may be disposed at a middle position of the PCB 500, so that the PCB 500 completely covers the opening of the movable groove 101 on the injection molded part 100, and at this time, the first interference portion 3022 is deformed toward the movable groove 101 by the pressing of the PCB 500.

In example three:

The spring leg 302 comprises a bending part 3021 and a first abutting part 3022, a first end of the bending part 3021 is connected with a first end of the spring 300, a second end of the bending part 3021 is connected with the first abutting part 3022, and the first abutting part 3022 is arranged outside the movable slot 101

The spring leg 302 further includes a second interference portion 3023 connected to an end of the first interference portion 3022 away from the bending portion 3021, and the second interference portion 3023 includes an interference surface 3024 parallel to the end surface of the first end of the spring 300.

Specifically, the component disposed on the PCB and in point contact with the first abutting portion 3022 to establish electrical connection may appear protruding on the horizontal plane of the PCB, so that when the first abutting portion 3022 abuts against the component, the second abutting portion 3023 may be closer to the dome 300, or even abut against the dome 300, so that the abutting surface 3024 parallel to the end surface of the first end of the dome 300 is disposed on the second abutting portion 3023, so that when the abutting condition between the second abutting portion 3023 and the dome 300 occurs, the abutting surface 3024 directly serves as the contact surface between the second abutting portion 3023 and the dome 300, and the surface area of the abutting surface 3024 contacting the dome 300 is larger, so that the situation of abutting against the dome 300 for multiple times can be realized in the same service life.

Further, the bending angle formed by the bending part 3021 and the end surface of the first end of the spring 300 ranges from 40 ° to 50 °.
