Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to a millimeter-wave radar shield. Background Technology

[0002] Millimeter-wave radar operates in the millimeter-wave frequency band (30-300GHz, wavelength 1-10mm) and is mainly used to detect the distance and angle of targets, and to calculate relative speed using distance data at different times. In vehicle applications, millimeter-wave radar usually needs to be used in conjunction with a shield to prevent radar radiation from interfering with the vehicle's infotainment system and to prevent frequent system crashes.

[0003] Currently, millimeter-wave radars in vehicles are typically installed on the sides and top of the vehicle body. During vehicle operation, the radar transmits signals through its transmitter to achieve positioning and navigation. However, when the vehicle is idle, most vehicles lack effective shielding protection for their millimeter-wave radar transmitters. While a fully enclosed shield can block radiation, it weakens the strength of the radar signal. Without sealing, the risk of radar radiation interfering with the vehicle's infotainment system increases. Utility Model Content

[0004] The purpose of this utility model is to provide a millimeter-wave radar shield in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A millimeter-wave radar shield includes a shield body and a millimeter-wave radar body disposed within the shield body, the shield body comprising:

[0007] The shielding cover is detachably connected to shielding cover one and shielding cover two. Shielding cover one has a through hole at one end that is compatible with the millimeter-wave radar body.

[0008] A split baffle covers the through hole;

[0009] The driving gear and driven gear are meshed together and are rotatably mounted on the shield.

[0010] A servo motor connected to a drive gear transmission;

[0011] The connecting plate is fixedly connected between the driving gear and the driven gear and each set of baffles.

[0012] As a further description of the above technical solution:

[0013] Two sets of transmission shafts are rotatably mounted on the shield. The driving gear and the driven gear are fixedly sleeved on the corresponding transmission shafts. The servo motor is mounted on the shield via a fixing plate. The output shaft of the servo motor is connected to the transmission shaft with the driving gear mounted on it via a coupling.

[0014] As a further description of the above technical solution:

[0015] The contact surface between the baffle and the shield is a smooth surface.

[0016] As a further description of the above technical solution:

[0017] One end of the shield is fixedly connected to a support plate that matches the movement trajectory of the baffle.

[0018] As a further description of the above technical solution:

[0019] The shielding cover has a fixed protrusion inside, which is fixedly connected to the millimeter-wave radar body by bolts.

[0020] As a further description of the above technical solution:

[0021] Flanges are fixedly fitted at the other end of shielding cover one and at both ends of shielding cover two, and the flanges on the opposite ends of shielding cover one and shielding cover two are fixedly connected by bolts.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. In this utility model, when the vehicle is idle, the servo motor drives the active gear to rotate in the forward direction and the driven gear to rotate in the reverse direction. The connecting plate drives the split baffle to swing along the support plate towards the middle until it completely covers the through hole, sealing the signal transmission port of the millimeter-wave radar body. This not only ensures the shielding effect of the shielding cover on radar radiation, but also avoids the weakening of radar signal strength by the fully enclosed shielding cover, effectively reducing the interference of radar radiation on the vehicle system.

[0024] 2. In this utility model, the support plate provides stable support and guidance for the baffle, enabling the baffle to slide accurately and smoothly along the predetermined trajectory, quickly opening the through hole, allowing the millimeter-wave radar body to smoothly transmit radar signals through the through hole and realize the target detection function.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-3 This utility model provides a technical solution: a millimeter-wave radar shield, including a detachably connected shield 1 and shield 3. Flanges 2 are fixedly fitted at the other end of shield 1 and both ends of shield 3. The flanges 2 on opposite ends of shield 1 and shield 3 are fixedly connected by bolts to form a closed shielding space. A boss 5 is fixedly connected inside shield 3, and the boss 5 is fixedly connected to the millimeter-wave radar body 4 by bolts, providing shielding protection for the millimeter-wave radar body 4 and preventing its radiation from affecting the vehicle's infotainment system. One end of shield 1 has a through hole 101 adapted to the millimeter-wave radar body 4, and a split baffle 7 covers the through hole 101. Two sets of drive shafts 13 are rotatably mounted on shield 1, with a drive gear 10 and a driven gear 9 fixedly mounted on them. The drive gear 10 and driven gear 9 are meshed and connected on the corresponding drive shaft 13. The servo motor 8 is mounted on the shield 1 through the fixing plate 11. The output shaft of the servo motor 8 is connected to the drive shaft 13 with the drive gear 10 through a coupling. The connecting plate 12 is fixedly connected between each set of drive shafts 13 and each set of baffles 7. When the servo motor 8 starts, it drives the drive shaft 13 with the drive gear 10 to rotate through the coupling. The drive gear 10 drives the driven gear 9 that meshes with it to rotate, which in turn causes the two sets of drive shafts 13 to drive the connecting plate 12 to move. The connecting plate 12 pulls the split baffles 7 to swing to both sides along the support plate 6, opening the through hole 101, so that the millimeter-wave radar body 4 can smoothly transmit radar signals through the through hole 101 to realize the target detection function.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the contact surface between the baffle 7 and the shield 1 is a smooth surface, which greatly reduces the friction between the two, allowing the baffle 7 to slide more smoothly and quickly.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, one end of the shield 1 is fixedly connected to a support plate 6 that is adapted to the movement trajectory of the baffle 7. The support plate 6 provides stable support and guidance for the baffle 7, enabling the baffle 7 to slide accurately and smoothly along the predetermined trajectory.

[0034] Working principle: When the vehicle is idle, the servo motor 8 drives the drive gear 10 to rotate in the forward direction and the driven gear 9 to rotate in the reverse direction. The connecting plate 12 drives the split baffle 7 to swing along the support plate 6 towards the middle. The support plate 6 plays a supporting and guiding role, ensuring that the baffle 7 smoothly closes towards the middle until it completely covers the through hole 101, sealing the signal transmission port of the millimeter-wave radar body 4. This not only ensures the shielding effect of the shielding cover on radar radiation, but also avoids the weakening of radar signal strength by the fully enclosed shielding cover, effectively reducing the interference of radar radiation on the vehicle system.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
