For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The camera provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0013] like Figures 1 to 32 As shown, the embodiment of the present application discloses a camera, which includes a housing 100, a wiper assembly 200 and a driving member 300. Optionally, the camera can be an outdoor camera. Optionally, the driving member 300 can be a driving device such as a motor, which is not specifically limited in the embodiment of the present application.

[0014] The housing 100 has a receiving cavity, and the housing 100 includes a connected shell 110 and a shooting window 120. Optionally, the shell 110 and the shooting window 120 can be sealed by a seal to prevent water stains, dust and other impurities in the external environment from entering the receiving cavity, thereby protecting the structure arranged in the receiving cavity, such as a lens, a speaker, etc. Optionally, the shooting window 120 can be a light-transmitting structure, specifically glass, etc., which is not specifically limited here. A through hole 121 is provided at the edge of the shooting window 120.

[0015] The wiper assembly 200 includes a connected rotating shaft 210 and a wiper 220. The wiper 220 can be movably arranged on the outer surface of the shooting window 120, that is, the wiper 220 can move relative to the outer surface of the shooting window 120 to scrape off water stains, dust and other impurities on the shooting window 120, thereby improving the clarity of the lens shooting picture. One end of the rotating shaft 210 extends through the through hole 121 to the accommodating cavity of the housing 100, and the rotating shaft 210 can rotatably seal with the shooting window 120 to prevent water stains, dust and other impurities from entering the interior of the camera.

[0016] The driving member 300 is arranged in the accommodating cavity of the shell 100, and the output shaft of the driving member 300 is connected to the rotating shaft 210. The driving member 300 can drive the wiper 220 to rotate along the outer surface of the shooting window 120 through the rotating shaft 210, so as to scrape off water stains, dust and other impurities on the outer surface of the shooting window 120 to ensure the clarity of the camera shooting picture, and the wiper 220 is adaptively pressed on the shooting window 120, that is, in the process of the driving member 300 driving the wiper 220 to rotate along the outer surface of the shooting window 120, the wiper 220 can adjust itself according to the change of the curvature of the outer surface of the shooting window 120, so that the wiper 220 is always in full contact with the shooting window 120.

[0017] In the embodiment of the present application, by opening a through hole 121 at the edge of the shooting window 120, the rotation axis 210 of the wiper assembly 200 is moved from the housing 110 of the camera to the shooting window 120, so as to shorten the distance between the rotation axis 210 and the central area of ​​the shooting window 120.

Therefore, the embodiment of the present application can solve the problem that the distance between the rotation axis 210 of the wiper assembly 200 of the current camera and the central area of ​​the shooting window 120 is long, resulting in poor wiping performance of the wiper assembly 200.

At this time, the sealing end face 413 of the sealing sleeve 410 is pressed against the first annular portion 421 of the sealing ring 420, which is conducive to improving the sealing between the sealing ring 420 and the inner surface of the shooting window 120, as well as the stability of the sealing ring 420, thereby preventing it from moving; and the contact area between the sealing sleeve 410 and the sealing ring 420 is also large, which is conducive to improving the sealing between the two.

[0023] In a further optional embodiment, the sealing sleeve 410 further includes a third sleeve section 414 connected to an end of the second sleeve section 412 away from the first sleeve section 411, and the third sleeve section 414 is disposed in the through hole 121.

The connecting sleeve 432 cooperates with the limiting end face 415 in the axial upper limit of the rotating shaft 210 to determine the distance between the annular pressure plate 431 and the end face of the third shaft sleeve segment 414 of the sealing shaft sleeve 410, thereby preventing the annular pressure plate 431 from exerting excessive pressing force on the second annular portion 423 and damaging the sealing ring 420, thereby extending the service life of the sealing ring 420.

[0025] Optionally, the compression amount of the sealing ring 420 can be 25-35% to form a good sealing effect.

In another optional embodiment, the inner surface of the sealing sleeve 410 is provided with a receiving groove 416, and the receiving groove 416 extends to the end surface of the sealing sleeve 410 facing the driving member 300. The sealing assembly 400 also includes an oil seal structure 440, which is arranged in the receiving groove 416, that is, the oil seal structure 440 is arranged in the receiving cavity of the housing 100, and the oil seal structure 440 is sealed with the rotating shaft 210. Since the oil seal structure 440 has good sealing performance, wear resistance, corrosion resistance, and convenient installation, the sealing sleeve 410 in this solution is sealed with the rotating shaft 210 through the oil seal structure 440, which is conducive to improving the sealing between the sealing sleeve 410 and the rotating shaft 210. Of course, the oil seal structure 440 may not be provided. In a further optional embodiment, the camera further includes an annular baffle 500 and a limiting ring 600.

Optionally, the rotation center axis of the protective cover 222c can be located in the middle part of the protective cover 222c in its length direction. The protective cover 222c can rotate relative to the bracket 222b around its rotation center axis so that the strip-shaped wiping member 222d is attached to the shooting window 120. The rotation center axis of the protective cover 222c extends along the width direction of the wiper 220. During the rotation of the wiper 220 relative to the shooting window 120, the elastic driving member 223 acts on the bracket 222b, and the rotation connection between the bracket 222b and the protective cover 222c transmits the force. When the curvature of the outer surface of the shooting window 120 changes, the protective cover 222c rotates relative to the bracket 222b around its rotation center axis so that the distances between the first part and the second part of the protective cover 222c located on the opposite sides of the rotation center axis and the shooting window 120 are substantially the same, so that the strip-shaped wiping member 222d acts evenly on the shooting window 120. At this time, the strip-shaped wiping member 222d can be attached to the shooting window 120, thereby increasing the wiping area of ​​the strip-shaped wiping member 222d, thereby improving its wiping efficiency.

It should be noted that the connecting protrusion 222c1 here has a certain deformation performance and can be deformed during the installation process. When at least part of the connecting protrusion 222c1 is inserted into the mounting hole 222b1, it recovers the deformation.

[0037] Optionally, the number of the first positioning surfaces 212 may be at least one, or the number of the first positioning surfaces 212 may be at least two, and the first positioning surfaces 212 are distributed at intervals along the circumference of the rotating shaft 210 , thereby improving the positioning stability between the wiper 220 and the rotating shaft 210 .

[0038] Optionally, the camera also includes a positioning member 700 arranged outside the accommodating cavity. Optionally, the positioning member 700 can be a nut. The positioning member 700 is threadedly connected to the rotating shaft 210. The positioning member 700 is located on the side of the wiper 220 away from the shooting window 120. The positioning member 700 and the wiper 220 are positioned and matched in the axial direction of the rotating shaft 210 to prevent the wiper 220 from tilting up, thereby ensuring that the wiper 220 can be stably pressed on the outer surface of the shooting window 120, so that the wiper 220 has better wiping performance.
