The protective shell 2 is provided with a light shield 3 for blocking light from the camera body 1. The light shield 3 is located above the camera body 1 so as to block the light from strong light sources such as the sun, prevent the light from shining directly on the wide-angle lens, and thus reflect and scatter it inside the wide-angle lens to ensure the image quality captured by the camera body 1.

[0030] Meanwhile, the light-shielding body 3 is slidably connected to the protective housing 2 so that the monitoring and camera management personnel can adjust the position of the light-shielding body 3 according to the actual light intensity in the shooting environment, thereby reducing or increasing the light-shielding effect of the light-shielding body 3 and improving the practicality of this embodiment.

[0031] The protective housing 2 is equipped with a moving component for controlling the movement of the light-shielding body 3, thereby facilitating the adjustment of the position of the light-shielding body 3 by monitoring and camera management personnel. Specifically, for example... Figures 3-4 As shown, the moving component in this embodiment mainly includes a drive motor 41, a drive disk 42, and a linkage rod 43 for linking the drive disk 42 with the light shield 3.

[0032] The motor seat for fixing and mounting the driving motor 41 should be arranged inside the protective shell 2, the driving disc 42 is linked with the output shaft of the driving motor 41, and the eccentric rotating shaft 421 is arranged on the driving disc 42 and is integrally formed with the driving disc 42, so that the connecting strength between the two is fully guaranteed, the linkage rotating shaft 31 is arranged on the light shielding body 3, and the two ends of the linkage rod 43 are rotationally connected with the linkage rotating shaft 31 and the eccentric rotating shaft 421 respectively, that is, the moving assembly in the embodiment adopts the linkage driving mode to push the light shielding body 3 to move, because the overall structure of the linkage driving structure is compact, under the premise of guaranteeing sufficient force to push the light shielding body 3 to move, the space required for installing the moving assembly can be effectively saved, and the overall structure of the linkage driving structure is simple, so that the later maintenance work is facilitated.

[0033] The driving motor 41 in the embodiment is preferably a servo motor, so that the moving assembly can accurately control the position of the light shielding body 3 by means of the high-precision characteristics of the servo motor; at the same time, in order to guarantee the stability of the rotation of the driving disc 42, the linkage column is arranged on the end of the driving disc 42 close to the driving motor 41, and the connection hole for connecting the output shaft of the driving motor 41 should also penetrate through the linkage column, that is, the driving disc 42 extends at the linkage column, so as to guarantee the contact area of the driving disc 42 and the output shaft of the driving motor 41, and guarantee the linkage work of the connection in a stable manner.

[0034] The light shielding body 3 comprises a sliding plate 32 and a light shielding plate 33, the sliding plate 32 is slidingly connected with the protective shell 2, the light shielding plate 33 is fixedly connected with the sliding plate 32, and the light shielding plate 33 is located at the end of the sliding plate 32 away from the linkage rod 43, that is, the light shielding plate 33 is moved in the mode that the moving assembly pushes the sliding plate 32 to move, the mounting plate 34 for arranging the linkage rotating shaft 31 is arranged on the end of the sliding plate 32 close to the linkage rod 43, the highest point of the mounting plate 34 is lower than the highest point of the sliding plate 32, and the highest point of the linkage rod 43 is arranged flush with the highest point of the sliding plate 32, so as to avoid that the inside of the protective shell 2 needs to be additionally provided with a cavity to guarantee the linkage relationship between the moving assembly and the sliding plate 32 and guarantee the structural strength of the protective shell 2 itself.

[0035] The projection of the light shielding body 3 on the horizontal plane is a horizontally arranged "T" shaped structure, the width of the light shielding plate 33 is smaller than the width of the sliding plate 32, that is, in the sliding process of the light shielding body 3, the light shielding plate 33 will not rub with the protective shell 2, so as to avoid that the light shielding plate 33 is gradually abraded due to movement and affects the light shielding effect; and the "T" shaped structure has good bearing capacity and high stability, reduces the influence of the impact generated when the light shielding body 3 moves to the limit distance under the action of the moving assembly and contacts with the protective shell 2 (the side wall of the sliding groove arranged in the protective shell 2 for the sliding of the light shielding body 3) on the light shielding body 3 itself, and guarantees the strength of the light shielding body 3 itself.

[0036] A plurality of balls 5 are arranged between the sliding plate 32 and the protective shell 2, and the balls 5 are arranged in a linear direction in sequence, so as to ensure the stability and smoothness of the sliding plate 32 in the protective shell 2; and the existence of the balls 5 can not only reduce the wear of the sliding plate 32 due to the sliding connection, but also facilitate the movement of the sliding plate 32 under the action of the moving assembly, and improve the smoothness and smoothness of the movement of the light shielding body 3.
