The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention.

[0029] Ultra Wideband (UWB) is a carrier-free communication technology that uses non-sinusoidal narrow pulses in the nanosecond to microsecond range to transmit data. The Federal Communications Commission (FCC) of the United States defines ultra-wideband as a radio technology with a bandwidth greater than 500MHz or a relative bandwidth greater than 20%. From the frequency domain, ultra-wideband is different from traditional narrowband and broadband, and its frequency band is wider. Usually narrowband refers to a relative bandwidth of less than 1%, and broadband refers to a relative bandwidth between 1% and 25%. Radio technology with a relative bandwidth greater than 25% and a center frequency greater than 500MHz is called ultra-wideband.

[0030] See also Figure 1 and Figure 2The positioning device 10000 includes a shell 1 and a circuit board 2. The circuit board 2 is arranged in the shell 1. The circuit board 2 includes a board body 21 and a circuit component arranged on the board body 21. The circuit component is used to receive, process and send ultra-wideband signals and communication signals with the outside world.

[0031] For the above case 1, see Figures 2 to 5 The housing 1 includes a box body 11 and a cover plate 12. The box body 11 is provided with a receiving groove and a clamping assembly 111. The cover plate 12 is used to cover the receiving groove to form a receiving cavity 110. The clamping assembly 111 is used to clamp and limit the circuit board 2. The box body 11 is provided with a positioning notch 112 on the side wall at one end of the receiving groove, and the box body 11 is provided with a connecting groove 113 extending from the outer side wall at the other end of the receiving groove. The bottom of the connecting groove 113 is provided with a connecting through hole 1130. The box body 11 is provided with a limiting step 114 around the edge of the groove of the receiving groove. The clamping assembly 111 includes a first limiting protrusion 1111 and a hook 1112. The first limiting protrusion 1111 and the hook 1112 are arranged in the receiving groove. One end of the first limiting protrusion 1111 is arranged at the groove bottom of the receiving groove. The other end of the first limiting protrusion 1111 is provided with a first step 11110. One side of the first limiting protrusion is fixedly arranged on the side wall of the receiving groove. One end of the hook 1112 is arranged at the groove bottom of the receiving groove. The other end of the hook 1112 is provided with a second step 11120. The hook 1112 is arranged at intervals from the side wall of the receiving groove. Along the height direction of the box body 11, the step surfaces for abutment of the first step 11110 and the second step 11120 are arranged oppositely, and the abutment directions of the first step 11110 and the second step 11120 are opposite.

[0032] A support protrusion 122 and a second limiting protrusion 121 are extended on the surface of the cover plate 12 facing the receiving groove, one end of the second limiting protrusion 121 is arranged on the cover plate 12, and the other end of the second limiting protrusion 121 is provided with a third step 1210. Along the height direction of the box body 11, the step surfaces for abutment of the third step 1210 and the first step 11110 are arranged oppositely, and the abutment directions of the third step 1210 and the first step 11110 are opposite. A positioning plate 123 is extended at one end of the cover plate 12, and a limiting convex strip 124 is extended around the edge of the cover plate 12. The positioning plate 123 is used to cooperate with the positioning notch 112, and plays a guiding and positioning role for the connection between the box body 11 and the cover plate 12. The limiting convex strip 124 is used to have an interference fit with the limiting step 114 to achieve the fixation of the box body 11 and the cover plate 12. Compared with fixing methods such as screw connection, it has lower cost and more convenient operation.

[0033] For the plate 21, see Figure 6The plate body 21 includes a first surface and a second surface that are arranged opposite to each other. The first surface is the surface of the plate body 21 that is away from the bottom of the receiving groove, and the second surface is the surface of the plate body 21 that faces the bottom of the receiving groove. The plate body 21 has limiting notches 210 on both sides. The limiting notches 210 are used for the hook 1112 to pass through and engage with the hook 1112. A convex plate 211 extends from one end of the plate body 21. The shape of the convex plate 211 matches the shape of the positioning notch 112. Please refer to Figures 7 to 9 When the plate 21 is installed in the receiving groove, the hook 1112 passes through the limiting notch 210, the first surface of the plate 21 at the limiting notch 210 abuts against the second step 11120, and the second surface of the plate 21 abuts against the first step 11110. When the box body 11 is covered with the cover plate 12, the first surfaces of both sides of the protruding plate 211 abut against the third step 1210, and the first surface abuts against the supporting protrusion 122.

[0034] It is worth noting that the first limiting protrusion 1111 and the hook 1112 relatively clamp the plate 21, so that the plate 21 does not move in the vertical direction in the box body 11, and the plate 21 is provided with a limiting notch 210, and the hook 1112 passes through the limiting notch 210, so that the plate 21 does not move in the horizontal direction in the box body 11, thereby achieving the fixation of the plate 21 in the box body 11. Further, the second limiting protrusion 121 is located on both sides of the protruding plate 211, which strengthens the horizontal limitation of the plate 21 in the shell 1, and the third step 1210 abuts the plate 21, which strengthens the vertical limitation of the plate 21 in the shell 1. In addition, the shape of the protruding plate 211 matches the positioning notch 112. When the plate 21 is removed from the box body 11, the protruding plate 211 can extend from the positioning notch 112 or force is applied to the protruding plate 211 of the plate 21 from the positioning notch 112, which is convenient for removal.
