Description

Technical Field

[0001] This utility model relates to the field of sensor distribution technology, and in particular to a direct-insertion radar sensor. Background Technology

[0002] The microstrip patch antennas commonly used in existing radar sensors are not suitable for extending directly from small holes in the lighting panel. Furthermore, the current installation method requires a relatively large exposed area when the radar sensor is installed parallel to the metal plate. Therefore, it is necessary to embed the microstrip patch antenna into the metal plate. However, if the distance between the microstrip patch antenna and the edge of the metal plate is small, the electromagnetic waves cannot be effectively radiated, affecting the antenna performance. Utility Model Content

[0003] The purpose of this invention is to address the technical problems existing in the background technology by proposing a direct-insertion radar sensor.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model in the first aspect is as follows:

[0005] A through-hole radar sensor includes a dielectric substrate, a transceiver chip, a bridge circuit, a triangular antenna, a feed port, and multiple gold finger pins. An insert plate is located on one side of the dielectric substrate. The transceiver chip is mounted on the dielectric substrate. The bridge circuit is mounted on the dielectric substrate and electrically connected to the transceiver chip. The triangular antenna is mounted within the dielectric substrate and has a feed point. The feed port is located on the dielectric substrate and electrically connected to both the transceiver chip and the feed point. Multiple gold finger pins are located on the upper and lower surfaces of the insert plate and electrically connected to the transceiver chip.

[0006] Preferably, the dielectric substrate is formed by bonding two dielectric substrates together.

[0007] Preferably, the triangular antenna is disposed between two dielectric substrates.

[0008] Preferably, the through-hole radar sensor further includes a grounding metal plate, which is mounted between two dielectric substrates.

[0009] Preferably, the dielectric substrate is made of FR4 material.

[0010] Preferably, the dielectric substrate is made of microwave dielectric material.

[0011] Preferably, the feed point is located at one corner of the triangular antenna.

[0012] Preferably, the height of the triangular antenna is less than 1 / 4 wavelength.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects: it includes a dielectric substrate, a transceiver chip, a bridge, a triangular antenna, a feed port, and multiple gold finger pins. A plug-in plate is provided on one side of the dielectric substrate. The transceiver chip is mounted on the dielectric substrate. The bridge is mounted on the dielectric substrate and electrically connected to the transceiver chip. The triangular antenna is mounted inside the dielectric substrate and has a feed point. The feed port is located on the dielectric substrate and electrically connected to the transceiver chip and the feed point, respectively. Multiple gold finger pins are respectively located on the upper and lower surfaces of the plug-in plate and electrically connected to the transceiver chip. The triangular antenna is used as the signal transceiver antenna. Due to the structural characteristics of the triangular antenna, the plug-in radar sensor can have a slender overall structure and easily protrude from the small hole opened on the lighting board, without affecting the performance and avoiding blocking the light from the LEDs on the lighting board.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or assembly referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 as well as Figure 2 As shown, this utility model proposes a through-hole radar sensor, which includes a dielectric substrate 100, a transceiver chip 200, a bridge 300, a triangular antenna 400, a feed port 500, and a plurality of gold finger pins 600. A plug plate 101 is provided on one side of the dielectric substrate 100. The transceiver chip 200 is mounted on the dielectric substrate 100. The bridge 300 is mounted on the dielectric substrate 100 and electrically connected to the transceiver chip 200. The triangular antenna 400 is mounted inside the dielectric substrate 100 and has a feed point 401. The feed port 500 is disposed on the dielectric substrate 100 and electrically connected to the transceiver chip 200 and the feed point 401, respectively. A plurality of gold finger pins 600 are respectively disposed on the upper and lower surfaces of the plug plate 101 and electrically connected to the transceiver chip 200.

[0029] Specifically, the dielectric substrate 100, as the fundamental support structure of the entire through-hole radar sensor, not only provides sufficient mechanical strength but also supports key components such as antennas and circuits. In this embodiment, the dielectric substrate 100 uses FR4 material or low-loss microwave dielectric material, which can effectively reduce signal loss during transmission and improve the overall performance of the radar sensor. The thickness of the dielectric substrate 100 also has a certain impact on performance; a thinner dielectric substrate helps to reduce the size of the antenna, while a thicker dielectric substrate 100 may provide more stable mechanical support. Therefore, in practical applications, it is necessary to select an appropriate dielectric substrate thickness according to specific requirements.

[0030] The insert 101 is disposed on one side of the dielectric substrate 100. In fact, the insert 101 and the dielectric substrate 100 are an integral structure. Therefore, the material and thickness of the insert 101 are the same as those of the dielectric substrate 100. Moreover, the upper and lower surfaces of the insert 101 are covered with a plurality of gold finger pins 600 for connection with other electronic products.

[0031] In this embodiment, the antenna is triangular in shape, and its unique shape and size design are crucial to its performance. Through precise calculation and optimized design, the triangular antenna 400 can achieve a wide beamwidth and low sidelobe level while ensuring sufficient gain. Moreover, the structural characteristics of the triangular antenna 400 allow the microwave motion sensor to have a slender overall structure, which can easily extend from the small hole in the illumination board. Therefore, without affecting the performance of the triangular antenna 400, it can also avoid blocking the light from the LEDs on the illumination board.

[0032] Furthermore, the dielectric substrate 100 is formed by bonding two dielectric substrates together, and the triangular plate antenna 400 is disposed between the two dielectric substrates. The through-hole radar sensor also includes a grounding metal plate 700, which is installed between the two dielectric substrates.

[0033] Furthermore, the feed point 401 is placed at one corner of the triangular plate antenna 400, and the height of the triangular plate antenna 400 is less than 1 / 4 wavelength.

[0034] Specifically, the 400-degree angled antenna has a low height and will not take up too much space, making it easy to install and use in small lighting homes.

[0035] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
