[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Combine the following Figure 1-Figure 9 The utility model is described as a handheld terminal NFC antenna installation structure, which includes a mainboard 100, a bracket 200 and an NFC antenna 300.

[0036] The mainboard 100 is fixed to the face shell 400 of the handheld terminal by screws. The mainboard 100 is provided with a contact spring 101 for docking with the NFC antenna 300. When the NFC antenna 300 contacts the contact spring 101, the circuit of the NFC antenna 300 is in a conducting state.

[0037] The bracket 200 is arranged on the main board 100, and an antenna installation position 201 is arranged on one side wall of the bracket 200. A first positioning protrusion 202 is arranged on one side end surface of the bracket 200 facing the main board 100, and the first positioning protrusion 202 corresponds to the contact spring 101;

[0038] Furthermore, the bracket 200 has a receiving cavity 203 inside, and the receiving cavity 203 is used to accommodate the scanning head 204. The side wall 201 of the bracket 200 provided with the antenna installation position is provided with a scanning window 205 connected to the receiving cavity 203, so that the scanning head 204 can perform scanning work, and the antenna installation position 201 is arranged around the outer periphery of the scanning window 205. It can be understood that the plane where the scanning window 205 is located is inclined with respect to the top end face of the handheld terminal, as shown in FIG. Figure 1 shown.

[0039] The NFC antenna 300 is disposed on the antenna installation position 201 , and a portion of the NFC antenna 300 extends along the outer surface of the bracket 200 to the first positioning protrusion 202 and contacts the contact spring 101 ;

[0040] Specifically, the NFC antenna 300 includes an antenna body 301 and a connecting piece 302. The antenna body 301 is used to generate an electromagnetic signal, and the connecting piece 302 is used to connect the antenna body 301 and the mainboard 100 so that the circuit of the antenna body 301 is conductive; the side of the antenna body 301 away from the bracket 200 (i.e., the front side of the antenna body 301) is used to transmit and receive signals, and the antenna body 301 is provided with a ferrite layer 303 on the side facing the bracket 200 (i.e., the back side of the antenna body 301) to enhance the electromagnetic signal.

[0041] Furthermore, the antenna body 301 is located in the antenna mounting position 201 and is arranged around the outer peripheral side of the scanning window 205. The connecting piece 302 is arranged along the outer surface of the bracket 200. The first end of the connecting piece 302 is located at the first positioning protrusion 202 and contacts the contact spring 101; the second end of the connecting piece 302 is connected to the antenna body 301.

[0042] Furthermore, in order to facilitate wiring, the connecting piece 302 is made of a flexible material. At the same time, in order to facilitate the assembly of the connecting piece 302, a first reinforcing plate 304 is provided on the first end of the connecting piece 302 on the side facing the first positioning protrusion 202, and a first positioning hole 305 is opened on the first reinforcing plate 304. The first positioning hole 305 passes through the connecting piece 302, and the first positioning protrusion 202 is penetrated by the first positioning hole 305;

[0043] The first end of the connecting piece 302 is provided with an antenna feeding point 306 on the side facing the contact spring piece 101, and the antenna feeding point 306 corresponds to the contact spring piece 101; when the antenna feeding point 306 contacts the contact spring piece 101, the circuit of the NFC antenna 300 is turned on;

[0044] A second reinforcement plate 307 is provided on the side surface of the second end of the connecting piece 302 facing the bracket 200, and there is a gap between the second reinforcement plate 307 and the antenna body 301 so that the second reinforcement plate 307 and the antenna body 301 can be bent relative to each other; a second positioning hole 308 is provided on the second reinforcement plate 307, and the second positioning hole 308 passes through the connecting piece 302, and the bracket 200 is provided with a second positioning protrusion 206 at the position corresponding to the second reinforcement plate 307, and the second positioning protrusion 206 passes through the second positioning hole 308.

[0045] It is understandable that the formation of the first positioning hole 305 and the second positioning hole 308 does not affect the circuit conduction function of the connecting piece 302 , and the first reinforcing plate 304 and the second reinforcing plate 307 are made of rigid materials.

[0046] It can be considered that the entire NFC antenna 300 can be fixed on the bracket 200 by means of mounting. Specifically, during assembly, adhesive can be applied to the side of the first reinforcement plate 304 facing the bracket 200, and then the first reinforcement plate 304 can be clamped at the first positioning protrusion 202 through the cooperation of the first positioning hole 305 and the first positioning protrusion 202, and the first reinforcement plate 304 can be bonded and fixed to the bracket 200. Similarly, the second reinforcement plate 307 can be bonded and fixed to the bracket 200 by the same operation. Finally, adhesive can be applied to the back of the antenna body 301, and the antenna body 301 can be bonded and fixed to the antenna installation position 201. Of course, in other embodiments, a third reinforcing plate 309, a fourth reinforcing plate (not shown), etc. may be provided on the connecting piece 302. There is a certain distance between adjacent reinforcing plates, which does not affect the bending of the connecting piece 302 when it is mounted on the surface of the bracket 200. The other reinforcing plates are fixed to the bracket 200 in the same mounting manner. The purpose of providing multiple reinforcing plates is to reinforce the connecting piece 302 and strengthen the fixation of the connecting piece 302 and the bracket 200. The several connection nodes of the connecting piece 302 may also be directly mounted on the bracket 200 with adhesive. After the NFC antenna 300 is mounted on the bracket 200, the bracket 200 is fixed to the mainboard 100 by screws. At this time, under the extrusion of the bracket 200, the antenna feed point 306 at the first end of the connecting piece 302 squeezes the contact spring 101 on the mainboard 100 to form a stable contact connection relationship, so that the circuit between the NFC antenna 300 and the mainboard 100 is conductive. At this point, the installation of the NFC antenna 300 is completed. After the handheld terminal product is finally assembled, the magnetic stripe card can be read at the scanning window 205 on the rear cover of the product.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
