Description

Technical Field

[0001] This utility model relates to the field of radar sensing technology, specifically a millimeter-wave radar sensor module. Background Technology

[0002] A millimeter-wave radar sensor module is an electronic device module that uses electromagnetic waves in the millimeter-wave frequency band to detect information about target objects. It mainly consists of a transmitting antenna, a receiving antenna, and a signal processing circuit. By transmitting millimeter-wave signals and receiving the echo signals reflected back from the target, the signal processing circuit analyzes and processes the echo signals to obtain information such as the distance, speed, and angle of the target object.

[0003] Existing millimeter-wave radar sensor modules are installed in the required location with bolts and then connected in series with the power supply via an interface to enable the device to function. However, due to the device's structure, the interface is exposed whether in use or not. When not in use, dust and other impurities can easily enter the interface. The connection between the interface and the cable connector is stable. When in use, there are no restraint components installed between the interface and the cable connector. When external force affects the cable too much, the cable connector can easily separate from the interface, thus affecting the normal operation of the device.

[0004] Therefore, it is necessary to propose a millimeter-wave radar sensor module. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a millimeter-wave radar sensor module that effectively shields the device's interface without hindering normal use, and also constrains cable connectors when they are connected to the interface, thus preventing connector detachment to some extent. This solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a millimeter-wave radar sensor module, comprising a radar sensing module body:

[0007] The radar sensing module body is provided with a connection component, the surface of the connection component is provided with a connection port, and the surface of the connection port is provided with a shielding and protective component.

[0008] The shielding and protective assembly includes a flexible outer liner with a slot. An arc-shaped elastic element is installed inside the slot. A semi-arc-shaped wrapping element one is installed on half of the outer surface of the slot, and a semi-arc-shaped wrapping element two is installed on the other half of the outer surface of the slot. A semi-arc-shaped adhesive element one is fixedly connected to the upper end of the semi-arc-shaped wrapping element one, and a semi-arc-shaped adhesive element two is fixedly connected to the upper end of the semi-arc-shaped wrapping element two. The inner sides of both ends of the semi-arc-shaped adhesive element two are bonded to the outer sides of both ends of the semi-arc-shaped adhesive element one.

[0009] Preferably, limiting plates are fixedly connected to both ends of the connecting assembly, and side connecting plates are fixedly connected to both sides of the flexible outer liner. The two sides of the side connecting plate are attached to the opposite inner sides of the two sets of limiting plates on one side. An adhesive layer is provided on the inner side of the side connecting plate, and the side connecting plate is bonded to the side of the connecting assembly through the adhesive layer.

[0010] Preferably, the arc-shaped elastic element is provided in eight groups, and the eight groups of arc-shaped elastic elements are arranged in a ring around the midpoint of the groove.

[0011] Preferably, the number of slots is the same as the number of connection ports, and the midpoint of the connection port and the midpoint of the slot are on the same straight line.

[0012] Preferably, the size of each group of arc-shaped elastic elements is the same, and the arc angle of each group of arc-shaped elastic elements is 45°.

[0013] Preferably, mounting components are provided on both sides of the radar sensing module body. The mounting components include connecting plates on both sides of the radar sensing module body, and the radar sensing module body is installed in the required position by bolts and the mounting components.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In use, this millimeter-wave radar sensor module features a flexible outer liner that engages with limiting plates on both sides of the connecting component via side connecting plates. It is then fixed to the connecting component via an adhesive layer on the inner side of the side connecting plates. By prying the two semi-circular wrapping pieces to the sides, the cable connector passes through a slot in the flexible outer liner, and the arc-shaped elastic element inside the slot protrudes downwards, connecting the cable connector to the connector. The two semi-circular wrapping pieces are then merged, with the two sides of the semi-circular adhesive piece on the second wrapping piece wrapping piece wrapping around the two outer sides of the semi-circular adhesive piece on the first wrapping piece, thus binding the cable surface. This structure effectively prevents obstruction of the interface space when it is in use or not, preventing dust and other debris from entering the interface. It also limits the connection of the cable to a certain extent, preventing excessive external force from causing the cable connector to detach, ensuring the safety of the interface in both use and non-use states.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A millimeter-wave radar sensor module, comprising a radar sensing module body 1:

[0027] A connection component 2 is provided on the main body 1 of the radar sensing module. A connection port 210 is provided on the surface of the connection component 2. A shielding and protective component 3 is provided on the surface of the connection port 210.

[0028] The shielding and protective component 3 includes a flexible outer liner 310, on which a slot 330 is formed. An arc-shaped elastic element 340 is installed inside the slot 330. A semi-arc-shaped wrapping element 350 is installed on one half of the outer surface of the slot 330, and a semi-arc-shaped wrapping element 360 is installed on the other half of the outer surface of the slot 330. A semi-arc-shaped fitting element 351 is fixedly connected to the upper end of the semi-arc-shaped wrapping element 350, and a semi-arc-shaped fitting element 351 is fixedly connected to the upper end of the semi-arc-shaped wrapping element 360. Part 2 361, the inner sides of both ends of the semi-arc-shaped adhesive part 361 are bonded to the outer sides of both ends of the semi-arc-shaped adhesive part 351. Limiting plates 220 are fixedly connected to both ends of the connecting component 2. Side connecting plates 320 are fixedly connected to both sides of the flexible outer liner 310. The two sides of the side connecting plate 320 are bonded to the relative inner sides of the two sets of limiting plates 220 on one side. An adhesive layer 321 is provided on the inner side of the side connecting plate 320. The side connecting plate 320 is bonded to the side of the connecting component 2 through the adhesive layer 321.

[0029] In use, the flexible outer liner 310 is engaged between the limiting plates 220 on both sides of the connecting component 2 by the side connecting plates 320 on both sides, and is fixed to the connecting component 2 by the adhesive layer 321 on the inner side of the side connecting plates 320. At this time, the semi-circular wrapping parts 350 and 360 are bent to both sides, and the cable connector required for connection passes through the slot 330 opened on the flexible outer liner 310, and pushes the arc-shaped elastic element 340 on the inner side of the slot 330 to protrude downward. At this time, the cable connector is connected to the connecting port 210. Then, the semi-circular wrapping parts 360 and 350 are merged.

[0032] Because the arc-shaped elastic element 340 has a certain elasticity and bendability, it can protrude inward or outward so that the cable connector can be connected to the connector 210. At the same time, when not in use, multiple sets of arc-shaped elastic elements 340 close to form a complete ring when not under force to block dust; when squeezed by the cable, they deform elastically to allow the cable to pass through.

[0033] As a preferred technical solution of this utility model, the number of slots 330 is the same as the number of connection ports 210, and the midpoint of the connection port 210 and the midpoint of the slot 330 are on the same straight line.
