Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an automotive radio frequency receiver module. Background Technology

[0002] In vehicles, radio frequency (RF) receiver modules are primarily used to output high-intensity radio signals from multiple antennas, enabling terminals to access the internet for information, entertainment, or mobile office work. Within vehicles, they are mainly used in applications such as in-vehicle infotainment systems, hands-free calling, and keyless start, serving as a communication technology that supports short-range device communication.

[0003] For example, CN207965128U, published on October 12, 2018, discloses a millimeter-wave radar, belonging to the field of radar technology. This millimeter-wave radar includes a housing, a cover, a power board, an RF board, and connectors. The housing has a cavity, and the power board is installed within the cavity. A first mounting groove is provided on the housing opposite the PIN hole of the power board. The connectors are detachably connected to the side of the housing away from the cavity. The PIN pins of the connectors can connect to the PIN holes of the power board through the first mounting groove. The RF board is installed at the cavity opening, and the cover is located outside the RF board and connected to the housing. The detachable connection of the PIN pins to the housing during installation results in a large overall structure, making installation difficult and impractical. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical automotive radio frequency receiver module. This invention integrates the PIN pins with the housing, thereby reducing the size of the PIN pin mounting structure on the housing, lowering the overall space occupied by the module within the vehicle, and thus increasing its practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: an automotive radio frequency receiver module, including a housing, wherein a PIN pin is provided inside the housing, the housing and the PIN pin are integrally formed, and a circuit board connected to the PIN pin is provided inside the housing.

[0006] The housing is provided with a mounting base, and the mounting base is provided with a PIN core. The PIN core is connected to a PIN needle, and the housing, PIN needle and PIN core are integrally injection molded parts.

[0007] The mounting base is provided with a side groove for one end of the PIN pin to extend out, and the housing is provided with a connector, the other end of the PIN pin extending into the connector.

[0008] The PIN pin is L-shaped and has an extension block that connects to the PIN core.

[0009] The PIN pin is provided with a deformable post, and the deformable post is provided with a deformable hole.

[0010] The end of the PIN pin is chamfered.

[0011] The mounting base is equipped with a positioning pin.

[0012] The mounting base is provided with a first positioning guide block connected to the housing, and the inner wall of the housing is provided with a second positioning guide block.

[0013] The beneficial effects of this utility model are:

[0014] By molding the housing and PIN pins into one piece, the PIN pins can be quickly installed on the housing without the need for an installation structure, thereby reducing the overall module size. The integrated, miniaturized, and easy-to-install RF module greatly saves on the process production cost of the RF module and improves the long-term stability of the sealing performance of the RF module in different environments.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figure 1-4As shown, the automotive radio frequency receiver module includes a housing 1, and a PIN pin 3 is provided inside the housing 1. The housing 1 and the PIN pin 3 are integrally formed. The housing 1 is provided with a circuit board 7 connected to the PIN pin 3. In this embodiment, there are six PIN pins 3, and the six PIN pins 3 are equally spaced.

[0023] By molding the housing 1 and PIN pin 3 into one piece, the PIN pin 3 can be quickly installed on the housing 1 without the need to design an installation structure, thereby reducing the overall module size. The integrated, miniaturized, and easy-to-install RF module greatly saves the process production cost of the RF module and improves the long-term stability of the sealing performance of the RF module in different environments.

[0024] The housing 1 is provided with a mounting base 2, and the mounting base 2 is provided with a PIN core 8. The PIN core 8 is connected to the PIN pin 3. The housing 1, PIN pin 3 and PIN core 8 are integrally injection molded parts. First, the PIN pin 3 and PIN core 8 are integrally molded by injection molding. Then, the PIN pin 3 and PIN core 8 are placed on the injection mold to perform the molding work of the housing 1, thereby realizing the molding work of the PIN pin 3 on the housing 1. The mounting base 2 is in contact with the end of the circuit board 7.

[0025] The mounting base 2 is provided with a side groove 9 for one end of the PIN pin 3 to extend out, and the housing 1 is provided with a connector 10. The other end of the PIN pin 3 extends into the connector 10, so as to facilitate the connection between the PIN pin 3 and the circuit board 7 inside the housing 1. The connector is inserted into the connector 10 to connect with the PIN pin 3.

[0026] The PIN pin 3 is L-shaped and has an extension block 301 that connects to the PIN core 8. The extension block 301 increases the connection area between the PIN pin 3 and the PIN core 8, thereby increasing the stability of the connection between the PIN pin 3 and the PIN core 8.

[0027] The PIN pin 3 is provided with a deformable post 302, and the deformable post 302 is provided with a deformable hole 303. When the PIN pin 3 is inserted into the circuit board 7, the deformable post 302 and the deformable hole 303 are deformed into the hole, thereby ensuring a stable connection between the PIN pin 3 and the circuit board 7.

[0028] The end of the PIN pin 3 is chamfered 304, which facilitates the connection between the PIN pin 3 and the circuit board 7 and the connector.

[0029] The mounting base 2 is provided with positioning pins 4, which cooperate with the circuit board 7 to ensure that the circuit board 7 is installed in the housing 1. Specifically, there are two positioning pins 4, which are symmetrically arranged on the mounting base 2.

[0030] The mounting base 2 is provided with a first positioning guide block 5 connected to the housing 1, and a second positioning guide block 6 is provided on the inner wall of the housing 1. The first positioning guide block 5 and the second positioning guide block 6 guide the movement of the circuit board 7. Specifically, the first positioning guide block 5 is located on the side of the housing 1 near the connector 10, and the second positioning guide block 6 is located on the adjacent sides of the housing 1. There are two of each of the first positioning guide block 5 and the second positioning guide block 6, and the ends of the second positioning guide block 6 are provided with guide surfaces.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
