[0045] Please refer to Figure 1 This application provides a multi-faceted radar 300 with a wide viewing angle. In this embodiment, the multi-faceted radar 300 can be installed on the wall of a building, such as a wall or corridor, or on the housing of a device, such as the housing of a car or detector. The multi-faceted radar 300 is used to sense information about target objects in the space where an object is located. Please refer to... Figure 2 The multi-faceted radar 300 includes a housing 8 and a radar module 4, which is installed inside the housing 8. The radar module 4 is used to detect information about target objects by reflecting electromagnetic waves. The information includes the target object's distance, speed, azimuth, and size.

[0046] The housing 8 includes a mounting surface 1, a fixing surface 2, and a connecting surface 3. The mounting surface 1, connecting surface 3, and fixing surface 2 are connected together to form a closed internal space 9. Please refer to [link / reference needed]. Figures 5-7 From the front view of the multi-faceted radar 300, the housing 8 is 130mm long and 52mm wide. From the side view of the multi-faceted radar 300, the housing 8 is 52mm long and 52mm wide. From the top view of the multi-faceted radar 300, the length of the housing 8 closest to the wall 5 is 130mm and the width is 52mm. The mounting surface 1 is used to fix the multi-faceted radar 300 to the wall 5, the connecting surface 3 is used to connect the mounting surface 1 and the fixing surface 2, and the fixing surface 2 is used to fix the radar module 4.

[0047] Please refer to Figure 4 Figure 5 The mounting surface 1 includes a body 10 and a locking slot 11. The locking slot 11 is disposed on the body 10 and is recessed inward relative to the body 10. The mounting surface 1 is fixed to the wall 5 by engaging with the fastener 7 through the locking slot 11. In this embodiment, the body 10 includes a base 101, a receiving portion 102, and a plurality of latches 103. The receiving portion 102 is a portion extending along one side of the base 101 toward the connecting surface 3, and the receiving portion 102 and the base 101 are perpendicular to each other. The latches 103 are disposed at the periphery of the body 10 and are used to connect the mounting surface 1 and the connecting surface 3 together. The base 101 includes a front and a back side disposed opposite to each other. When the mounting surface 1 is mounted on the wall, the front side faces the target area and the back side faces the wall to which it is mounted. The target area is the detection area of ​​the multi-faceted radar 300 and is determined according to the field of view range of the multi-faceted radar 300. The mounting slot 11 includes a first mounting slot 110 and a second mounting slot 111. The first mounting slot 110 is located on the back of the base 101, and the second mounting slot 111 is located on the receiving part 102. The first mounting slot 110 and the second mounting slot 111 are connected together. The mounting surface 1 is fixed to the wall 5 through the cooperation of the first mounting slot 110, the second mounting slot 111, and the fastener 7. Specifically, the fastener 7 is first fixed to the wall 5 with screws, and then the fastener 7 is respectively engaged with the first mounting slot 110 and the second mounting slot 111, so that the base 101 is installed on the wall 5, and the back of the base 101 faces the wall 5; the receiving part 102 of the mounting surface 1 is installed on the ceiling 6. The above-mentioned installation of the multi-faceted radar 300 on the wall 5 by using the fastener 7 as a medium facilitates the disassembly of the multi-faceted radar 300 and avoids damage to the housing 8 of the multi-faceted radar 300.

[0048] The fixing surface 2 includes a first fixing surface 20 and a second fixing surface 21, which are symmetrically arranged on both sides of the mounting surface 1. The fixing surface 2 is made of a material that can transmit radar signals, such as aerospace wave-transparent material or optical glass. In this embodiment, the first fixing surface 20 is located on one side of the base 101, with a horizontal inclination angle of 45° between the first fixing surface 20 and the base 101, and a vertical angle of 35° between the first fixing surface 20 and the base 101. The second fixing surface 21 is located on the other side of the base 101, with a horizontal inclination angle of 45° between the second fixing surface 21 and the base 101, and a vertical angle of 35° between the second fixing surface 21 and the base 101. The first fixing surface 20 and the second fixing surface 21 have a symmetrical structure. The thickness of both the first fixing surface 20 and the second fixing surface 21 is 4 mm, and their height is 36 mm. The installation positions of the first fixed surface 20 and the second fixed surface 21 can satisfy the detection range of the multi-faceted radar 300 in the horizontal direction of ±60°, and at the same time, it can also detect a large angle range from above, thus satisfying the requirement of detecting the behavior of target objects from a high place.

[0049] The connecting surface 3 is located between the first fixing surface 20 and the second fixing surface 21, and faces the front of the base 101. The connecting surface 3 is used to connect the first fixing surface 20 and the second fixing surface 21, and connects to the mounting surface 1. In this embodiment, the connecting surface 3 includes several slots 31 and several status light holes 32. The slots 31 are located at the periphery of the connecting surface 3 and correspond to the buckles 103 on the body 10. The status light holes 32 penetrate the connecting surface 3. The slots 31 are used to engage with the body 10 via the buckles 103. The connecting surface 3 is integrally formed with the two fixing surfaces 2. When the connecting surface 3 is fixed to the mounting surface 1 by the engagement of the buckles 103 and the slots 31, the first fixing surface 20 and the second fixing surface 21 are naturally also fixed to the mounting surface 1. The two status light holes 32 are used to display the working status of the radar module 4, so as to facilitate timely handling when the radar module 4 malfunctions. The diameter of the status light holes 32 is 3mm. The length between the two connection points of the connecting surface 3, which connect the first fixing surface 20 and the second fixing surface 21 and are close to the receiving part 102, is 40.5 mm. The connecting surface 3 adopts a curved surface design to improve the smoothness of the product surface. In some feasible embodiments, the connecting surface 3 can also be connected to the fixing surface 2 by a connector, such as a screw or glue.

[0050] Radar module 4 includes a first radar module 40 and a second radar module 41, which are symmetrically arranged on the inner sides of the first fixed surface 20 and the second fixed surface 21, respectively. The first radar module 40 and the second radar module 41 transmit radar signals to their respective fixed surfaces 2, and the radar signals transmit through the fixed surfaces 2 to sense information about objects. The field of view of the first radar module 40 is the same as that of the second radar module 41. The field of view of the multi-faceted radar 300 with a large viewing angle is the sum of the field of view of the first radar module 40 and the second radar module 41. In this embodiment, the field of view of the first radar module 40 is 120°, the field of view of the second radar module 41 is 120°, and the total field of view of the multi-faceted radar 300 is 240°. When the multi-faceted radar 300 is installed on the wall 5, the detection range of the radar is extended to 240° while maintaining a horizontal detection range of 180°. This application enables the simultaneous sensing of multiple radar modules 4 by symmetrically arranging radar modules 4 on different sides of a multi-faceted radar 300, and by combining the data from multiple radar modules 4, thereby expanding the field of view of the radar sensor.

[0051] The dimensions, shapes, and materials of the various components of the multi-faceted radar 300 mentioned above are merely examples and can be set according to actual needs; no limitations are imposed here.

[0052] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

[0053] The above-listed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application.
