[0028] The following is a further detailed description in conjunction with the attached Figures 1 - 3 This application is further described in detail.

[0029] Refer to Figure 1As shown in the figure, a pupil distance adjustment mechanism includes an adjustment bracket 1, two lens barrels 2, and an adjustment component. Installation grooves 11 are provided on both sides of the bottom of the adjustment bracket 1. An installation cavity 12 is provided between the two installation grooves 11 of the adjustment bracket 1. Sliding channels 13 are provided between the two installation grooves 11 and the installation cavity 12. The installation cavity 12 communicates with the two installation grooves 11 through the two sliding channels 13. A circuit board 3 is arranged in the installation cavity 12. Connection seats 4 are arranged at the tops of the lens barrels 2. The tops of the connection seats 4 are arranged in the installation grooves 11. A wire passing channel 41 is arranged on the connection seat 4. One end of the wire passing channel 41 is slidably arranged in the sliding channel 13, and the other end extends outside the installation groove 11 and communicates with the lens barrel 2. The adjustment component is used to adjust the distance between the two connection seats 4. In this way, when in use, the circuit board 3 is placed in the installation cavity 12, and the cable connecting the circuit board 3 and the lens barrel 2 passes through the wire passing channel 41 at the sliding channel 13 and finally passes out of the wire passing channel 41 into the lens barrel 2. There is no need to open a wire passing hole on the adjustment bracket 1, which improves the environmental performance such as the sealing performance of the device. At the same time, the cable is not exposed, and the electromagnetic compatibility is better.

[0030] Reference Figure 1 As shown in the figure, the wire passing channel 41 includes a first wire passing channel and a second wire passing channel. The first wire passing channel is slidably arranged in the sliding channel 13. The second wire passing channel is connected to the first wire passing channel. The second wire passing channel extends outside the installation groove 11 and communicates with the lens barrel 2. The first wire passing channel and the second wire passing channel are preferably arranged in an L shape. When the second wire passing channel slides in the installation groove 11, the first wire passing channel slides in the sliding channel 13. In order to improve the sealing performance between the wire passing channel 41 and the sliding channel 13, a sealing ring 5 is arranged on the circumferential side of the first wire passing channel to seal between the outside of the wire passing channel 41 and the inside of the sliding channel 13.

[0031] Further optimized, reference Figure 1 As shown in the figure, in order to improve the connection stability between the connection seat 4 and the lens barrel 2, a fixed flange 6 connected to the lens barrel 2 is arranged at the bottom of the connection seat 4. The fixed flange 6 is installed on the lens barrel 2 through a plurality of bolts, which ensures the connection stability and is convenient for disassembly, installation and maintenance.

[0032] Reference Figures 1 - 3As shown in the figure, in order to facilitate the adjustment of the positions of the two lens barrels 2, the adjustment assembly includes two adjustment screws 7. The two adjustment screws 7 are respectively rotatably arranged at both ends of the adjustment bracket 1. One end of each of the two adjustment screws 7 extends into the installation groove 11 and is respectively threadedly connected to the two connecting seats 4 (nuts are installed on the connecting seats 4 or threaded holes are provided to enable threaded connection with the adjustment screws 7). The axial direction of the adjustment screw 7 is the same as the sliding direction of the connecting seat 4. In this way, by rotating the adjustment screw 7, the connecting seat 4 threadedly connected to the adjustment screw 7 moves along the axial direction of the adjustment screw 7 to achieve the purpose of adjusting the distance between the two lens barrels 2. Moreover, in order to improve the installation stability of the adjustment screw 7, both ends of the adjustment screw 7 are rotatably connected to the adjustment bracket 1. And in order to facilitate the screwing of the adjustment bolt 7, adjustment sleeves are provided at the mutually remote ends of the two adjustment screws 7, and anti-slip ribs are provided on the adjustment sleeves to facilitate holding the adjustment sleeves and screwing the adjustment bolts 7.

[0033] Further optimized, as Figure 3 shown, in order to limit the movement of the connecting seat 4, a limiting groove 42 is provided at the top end of the connecting seat 4, and two limiting bolts 14 are provided on the adjustment bracket 1. The bottom ends of the limiting bolts 14 extend into the limiting groove 42. When the two sides of the limiting groove 42 abut against the limiting bolts 14, the connecting seat 4 cannot move in the corresponding direction, so that the first wire passing channel cannot be separated from the sliding channel 13. When it is necessary to remove the connecting seat 4, the limiting bolts 14 are screwed outward so that the connecting seat 4 can move continuously away from the side of the installation cavity 12 until the first wire passing channel is separated from the sliding channel 13, and the connecting seat 4 can be taken out from the installation groove 11.

[0034] As Figure 1 shown, in order to facilitate the installation and maintenance of the circuit board 3, the opening of the installation cavity 12 is provided at the bottom of the adjustment bracket 1. The adjustment bracket 1 is provided with a cover plate 8 at the opening of the installation cavity 12, and the circumferential side of the cover plate 8 is clamped on the adjustment bracket 1. In this way, the installation cavity 12 is sealed by the cover plate 8 clamped on the adjustment bracket 1, which facilitates the installation and maintenance of the circuit board 3 and also ensures the sealing performance of the device.

[0035] The working principle of the present utility model: During use, the circuit board 3 is placed in the installation cavity 12, and the cable connecting the circuit board 3 and the lens barrel 2 passes through the wire passing channel 41 at the sliding channel 13 and finally passes out of the wire passing channel 41 into the lens barrel 2. There is no need to provide wire passing holes on the adjustment bracket 1, which improves the environmental performance such as the sealing performance of the device; at the same time, the cable is not exposed, and the electromagnetic compatibility is better.

[0036] The above are only the preferred embodiments of this application, and the present utility model is not limited to the above embodiments. It can be understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present utility model should be considered to be included within the protection scope of the present utility model.
