DETAILED DESCRIPTION

[0017] like Figure 1-3 As shown, the utility model provides a walkie-talkie back clip device integrated with ultra-wideband UWB positioning technology, including a shell body that is buckled on the rear end of the walkie-talkie, and also includes a mounting slot 1 arranged in the shell body, a PCB board 2 arranged in the mounting slot 1, a switch button arranged on the PCB board 2, a button hole 3 arranged on the bottom of the mounting slot 1, a battery 4 arranged in the mounting slot 1 and electrically connected to the PCB board 2, and a cover plate 5 arranged on the opening of the mounting slot 1, wherein the button hole 3 corresponds to and fits with the switch button, and the cover plate 5 covers the opening of the mounting slot 1.

[0018] The shell is a back shell buckled on the back of the walkie-talkie, and the PCB board 2 and the battery 4 are installed in the installation groove 1 on the shell. The installation groove 1 is closed with a cover plate 5. The UWB positioning module is integrated on the PCB board 2, including a UWB transmitter and a receiver, and high-precision positioning (centimeter-level accuracy) is achieved by using nanosecond pulse signals. Even in an environment with severe multipath interference and shielding, stable positioning performance can be maintained. A switch button is installed on the back of the PCB board 2 to control the start and stop of the power supply of the PCB board 2. The switch button corresponds to the button hole 3 on the shell. The switch button can be pressed from the rear end face of the shell, which is easy to use. This structure integrates the positioning function into the walkie-talkie back clip. The shell can be buckled on a traditional walkie-talkie to provide the positioning function without changing the walkie-talkie itself. The shell is compatible with the shape of the walkie-talkie, and it can be buckled on the walkie-talkie. The design has a simple structure, is easy to use, and has low cost.

[0019] like Figure 1-3 As shown, it also includes a switch button 6 embedded in the button hole 3, a limiting strip plate 7 fixed on the inner end of the switch button 6, and a mounting groove arranged on the bottom of the mounting groove 1 and corresponding to the limiting strip plate 7. The switch button 6 is cylindrical, one end of the limiting strip plate 7 is fixed to the inner end of the switch button 6, and the other end is horizontally suspended. Four limiting strip plates 7 are provided and are arranged in a circumferential array on the inner end of the switch button 6. The limiting strip plates 7 are embedded in the mounting groove.

[0020] A switch button 6 is embedded in the button hole 3 , and the switch button 6 is pressed tightly against the switch button, which is convenient for manual pressing. The mounting slot limits and positions the limiting strip 7 , which is convenient for the installation of the switch button 6 .

[0021] like Figure 1-3 As shown, the shell includes a back plate 8, a lower baffle 9, a left baffle 10 and a right baffle 11 enclosed at the lower end, left and right sides of the back plate 8, the upper end of the back plate 8 is inclined inward, and the mounting groove 1 is arranged on the inner end surface of the back plate 8.

[0022] The lower baffle 9, the left baffle 10 and the right baffle 11 are surrounded at the lower end and both sides of the back plate 8 in a total of three directions to form a housing with a groove-type structure. Compared with the housing surrounded on all four sides, it has a wider range of applications. The back plate 8, the lower baffle 9, the left baffle 10 and the right baffle 11 are an integrated structure. The mounting groove 1 is located on the inner end surface of the back plate 8. The upper end of the back plate 8 is tilted inward to increase the installation space of the mounting groove 1.

[0023] like Figure 1-3 As shown, the upper edges of the lower baffle plate 9, the left baffle plate 10 and the right baffle plate 11 are provided with inwardly bent arc flanges 12.

[0024] The cross-section of the arc flange 12 is arc-shaped, and it is an integral structure with the lower baffle 9, the left baffle 10 and the right baffle 11. The edge refers to the end of the lower baffle 9, the left baffle 10 and the right baffle 11 facing away from the back plate 8. The arc flange 12 is buckled on the corner of the intercom, making the shell and the intercom more compact after buckling, and easier to install.

[0025] like Figure 1-3 As shown, the lower baffle 9, the left baffle 10 and the right baffle 11 are all provided with a button hole 13 and a port hole 14. After the upper housing is buckled, the button hole 13 and the port hole 14 correspond to the buttons and other ports of the intercom, and do not hinder use.

[0026] like Figure 1-3 As shown, the mounting slot 1 is also provided with a charging port 15 connected to the battery 4, and the lower baffle 9 or the left baffle 10 or the right baffle 11 is provided with a charging hole corresponding to the charging port 15. The battery 4 is a rechargeable battery, which can be charged through the charging port 15 for continuous and repeated use.

[0027] like Figure 1-3 As shown, a plurality of anti-skid grooves 16 are arranged on the outer end surfaces of the lower baffle 9, the left baffle 10 and the right baffle 11. The anti-skid grooves 16 increase the friction force when holding the hand, and prevent the walkie-talkie from falling after the hand slips.
