[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figures 1 to 5As shown, an automobile antenna device 10 of an embodiment includes a housing 100, a circuit board 200, a vehicle antenna 300, a welding piece 400 and a riveting piece 500. The circuit board 200 is installed inside the housing 100. The housing 100 is provided with a through slot 110. One end of the vehicle antenna 300 passes through the through slot 110. The welding piece 400 is welded to the vehicle antenna 300 and the circuit board 200 respectively. The vehicle antenna 300 is provided with a riveting hole. The welding piece 400 includes a first welding portion 410 and a second welding portion 420. The first welding portion 410 is fixedly connected to the second welding portion 420. The first welding portion 410 is welded to the vehicle antenna 300, and the second welding portion 420 is welded to the circuit board 200. One end of the rivet 500 passes through the rivet hole and is connected to the first welding portion 410. The other end of the rivet 500 is bent to clamp a side of the vehicle antenna 300 away from the welding portion 400 to further fix the vehicle antenna 300. The width of the first welding portion 410 is greater than the width of the second welding portion 420.

[0034] In this embodiment, the welding member 400 is made of metal, such as tin or copper, etc. The first welding portion 410 and the second welding portion 420 are integrally formed, and the vehicle antenna 300 and the circuit board 200 are fixed by the first welding portion 410 and the second welding portion 420, so that the circuit board 200 and the vehicle antenna 300 are electrically connected, so that the signal received by the vehicle antenna 300 is transmitted to the circuit board 200. Further, one end of the rivet 500 passes through the rivet hole and is connected to the first welding portion 410, and the other end of the rivet 500 is bent and clamped to the side of the vehicle antenna 300 away from the welding member 400, so as to further fix the vehicle antenna 300, so that the connection strength between the vehicle antenna 300 and the circuit board 200 is higher through the joint action of the welding member 400 and the rivet 500. Further, the width of the first welding portion 410 is increased, so that the connection strength between the first welding portion 410 and the rivet 500 is higher.

[0035] In the above-mentioned automobile antenna device 10, the circuit board 200 is installed inside the housing 100, one end of the vehicle antenna 300 passes through the through slot 110 of the housing 100 and is welded to the welding piece 400, and the welding piece 400 is also welded to the circuit board 200, so that the circuit board 200 and the vehicle antenna 300 are connected through the welding piece 400, one end of the rivet 500 passes through the rivet hole and is connected to the welding piece 400, and the other end of the rivet 500 is bent and clamped to the side of the vehicle antenna 300 away from the welding piece 400, so as to further fix the vehicle antenna 300. Specifically, the welding piece 400 and the rivet 500 cooperate together to make the connection strength between the vehicle antenna 300 and the circuit board 200 higher, so as to avoid the situation where the vehicle antenna 300 and the circuit board 200 have poor contact.

[0036] In one embodiment, the riveted member 500 is a rivet, so that the vehicle antenna 300 is further fixed by the rivet.

[0037] like Figure 3 As shown, in one embodiment, the rivet 500 is connected to the side of the welding member 400. In this embodiment, the rivet 500 is connected to the side of the welding member 400, and the bottom of the welding member 400 is respectively welded to the vehicle antenna 300 and the circuit board 200, so that the structure of the rivet 500 and the welding member 400 is more compact. Of course, in other implementations, the rivet 500 can also be connected to the top of the welding member 400.

[0038] like Figure 3 As shown, in one embodiment, the number of the rivet members 500 is multiple, the number of the rivet holes is multiple, the multiple rivet holes are arranged at intervals along the periphery of the welding member 400, and the multiple rivet members 500 are arranged one-to-one with the multiple rivet holes. In this embodiment, the multiple rivet members 500 are arranged at intervals on the periphery of the welding member 400, and the bottom of each rivet member 500 is bent and abuts against the vehicle antenna 300, so that the fixing effect of the vehicle antenna 300 is better through the multiple rivet members 500.

[0039] like Figure 3 As shown, in one embodiment, a protective layer 600 is provided on one side of the vehicle-mounted antenna 300 adjacent to the welding piece 400, and the protective layer 600 is welded to the welding piece 400. In this embodiment, the protective layer 600 covers the circuit layer of the vehicle-mounted antenna 300, and the circuit layer is a metal, such as a silver layer or a copper layer, which is easily oxidized in the air, resulting in poor contact between the circuit layer and the circuit board 200. By covering the circuit layer with the protective layer 600, the protective layer 600 is not easy to oxidize, and a protective effect is achieved. At the same time, the protective layer 600 also has conductive properties, so that the vehicle-mounted antenna 300 and the circuit board 200 are connected.

[0040] In one embodiment, the protective layer 600 is a graphene protective layer. In this embodiment, the protective layer 600 is made of graphene, which has excellent electrical conductivity and high hardness, so that the connection strength between the graphene and the welding part 400 is high.

[0041] like Figure 1 As shown, in one embodiment, a through hole 120 is provided on the periphery of the housing 100, and the through hole 120 is used for the limit post of the car to pass through. It can be understood that the limit post of the car passes through the through hole 120 to fix the housing 100.

[0042] The present application also provides a new energy vehicle, comprising the vehicle antenna device 10 described in any one of the above embodiments.

[0043] Compared with the prior art, the present invention has at least the following advantages:

[0044] In the above-mentioned automobile antenna device 10, the circuit board 200 is installed inside the housing 100, one end of the vehicle antenna 300 passes through the through slot 110 of the housing 100 and is welded to the welding piece 400, and the welding piece 400 is also welded to the circuit board 200, so that the circuit board 200 and the vehicle antenna 300 are connected through the welding piece 400, one end of the rivet 500 passes through the rivet hole and is connected to the welding piece 400, and the other end of the rivet 500 is bent and clamped to the side of the vehicle antenna 300 away from the welding piece 400, so as to further fix the vehicle antenna 300. Specifically, the welding piece 400 and the rivet 500 cooperate together to make the connection strength between the vehicle antenna 300 and the circuit board 200 higher, so as to avoid the situation where the vehicle antenna 300 and the circuit board 200 have poor contact.

[0045] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
