Referring to fig. 1, fig. 1 shows a prior art camera structure with a cleaning assembly, which includes a motor 01, a gear set 02, a rotating shaft 03, a wiper frame 04, a wiper 05, and a ball cover 06, wherein: the rotary motion output by the motor 01 is transmitted to the rotating shaft 03 through the gear set 02 to drive the rotating shaft 03 to rotate by taking the axis shown in the figure as the shaft; the wiper frame 04 is fixedly installed with the rotating shaft 03, and the wiper 05 is installed on the wiper frame 04, when the rotating shaft 03 rotates, the part of the wiper frame 04 on which the wiper 05 is installed rotates around the same axis, so that the wiper 05 is driven to scrape the surface of the spherical cover 06.

In the above-mentioned conventional camera structure, in order to enable the wiper 05 to scrape the entire window area of the ball cover 06, the rotation axis of the rotating shaft 03 should be kept flush with the bottom of the ball cover 06, so that the rotating shaft 03 and the bearing for supporting the rotating shaft 03 will necessarily block a part of the window area of the ball cover 06, no matter where the wiper frame 04 and the wiper 05 are stopped.

In order to solve the problem of window shielding of the ball cover by the cleaning assembly, referring to fig. 2 and 3, the camera according to an embodiment of the present utility model includes a camera body, a ball cover 100 connected to one end side of the camera body, a cleaning assembly 200, and a housing 300. Wherein: referring to the orientation shown in fig. 3, the upper side of the housing 300 is used to mount the camera body, while the ball cover 100 and part of the cleaning assembly 200 are located below the housing 300.

The cleaning assembly 200 includes a rotary ring 21 and a wiper device 22, wherein: the outer peripheral side of the rotary ring 21 is provided with a motion input portion 211 for receiving an external motion input to drive the rotary ring 21 to rotate with respect to the camera body outside the window range of the ball cover 100. In the illustrated embodiment, the motion input portion 211 is provided as an external gear structure, the camera further includes a motor capable of rotating in two directions with the driving member 23 and the transmission member 24, the output shaft of the motor is connected to the transmission member 24, and the transmission member 24 is provided as a gear and can be meshed with the motion input portion 211 to drive the driving member 23 to rotate the rotating ring 21.

It will be appreciated that in other embodiments, the driving member 23 and the transmission member 24 may be other devices/components capable of performing the same function, or the driving member 23 may be powered by other external power sources.

The rotating ring 21 is disposed around the outer side of the ball cover 100, and the rotating ring 21 itself does not cover the window range of the ball cover 100. The inner peripheral side of the rotary ring 21 is provided with an installation limiting groove 212. On the basis of fig. 2 and 3, further in conjunction with fig. 4, the mounting-limiting groove 212 includes a side wall a and a bottom wall B.

The wiper device 22 includes a supporting member 221 and a cleaning member 222, and in some embodiments, the cleaning member 222 is selected as a wiper made of rubber. The supporting member 221 includes a pivot portion 2211 pivotally connected to the bottom wall B, and a mounting portion 2213 and a limiting portion 2212 respectively located at two sides of the pivot portion 2211, the cleaning member 222 is mounted on the mounting portion 2213, and the cleaning member 222 abuts against an outer side surface of the ball cover 100, and a friction force exists between the cleaning member 222 and the ball cover 100 due to the abutting force.

As shown in fig. 4 and 7, when the driving member 23 drives the rotating ring 21 to rotate in the direction S1 through the driving member 24 and the motion input portion 211, the direction of the friction force between the cleaning member 222 and the ball cover 100 is opposite to the direction S1, under the action of the friction force, the supporting member 221 can swing relative to the rotating ring 21 to a working position with a preset included angle between one side end surface thereof, and the limiting portion 2212 of the supporting member 221 can abut against the side wall a of the mounting limiting groove 212 to limit, so that the supporting member 221 is kept at the working position, and the cleaning member 222 scrapes the outer side surface of the ball cover 100 along with the continued rotation of the rotating ring 21, thereby completing the cleaning work.

As shown in fig. 4, in combination with fig. 5 and 7, when the rotating ring 21 is rotated in the S2 direction by the driving of the driving member 23, the direction of friction force between the cleaning member 222 and the ball cover 100 is opposite to the S2 direction, and the supporting member 221 can swing relative to the rotating ring 21 to a storage position relatively close to one end surface of the rotating ring 21, the storage position being located outside the window range of the ball cover 100 by the friction force.

In the camera of the above embodiment, since the motion input portion 211 is located on the outer peripheral side of the rotary ring 21, the inner peripheral side of the rotary ring 21 reserves a relatively large space, which is advantageous for accommodating a larger-sized camera body related structure. Meanwhile, in the storage position, the wiper device 22 is relatively close to one end face of the rotating ring 21, and even can be completely retracted into the rotating ring 21, so that the wiper device 22 does not occupy an extra space substantially when the cleaning ball cover 100 is not required, and the installation space of the cleaning assembly 200 does not need to be reserved greatly. This structure makes it possible to make the cleaning assembly 200 more compact than the manner in which the wiper device 22 is provided on one side end face of the rotary ring 21.

With continued reference to fig. 4, a receiving groove 213 is provided on one end surface of the rotary ring, and in the receiving position, the mounting portion 2213 and the cleaning piece 222 can swing into the receiving groove 213, so that the wiper device 22 in the receiving position is completely retracted into the rotary ring 21.

Referring to the relevant marks in fig. 4, the receiving groove 213 communicates radially inward to the inner peripheral side of the rotary ring 21. The accommodating groove 213 has a side wall D and a bottom wall C, and in the accommodating position, the cleaning piece 222 protrudes to the inner peripheral side of the rotating ring 21 in a direction opposite to the side wall D, and is held in pressing contact with the outer surface of the ball cover 100.

In this way, when the rotary ring 21 rotates in the S1 direction, the cleaning member 222 and the ball cover 100 always maintain the abutting and contacting relationship, and therefore, the friction force therebetween can drive the wiper device to swing from the storage position to the working position rapidly.

In the working position, the supporting member 221 is perpendicular to the one end surface of the rotating ring 21, that is, the aforementioned "preset included angle" is set to 90 degrees, and at this time, the limiting portion 2212 is in abutting connection with the side wall a surface for limiting. In this way, the support 221 can be kept in the working position more reliably.

With continued reference to fig. 4, the cleaning member 222 is configured as a wiper having a first curvature, and the ball cover 100 has a second curvature, where the first curvature is smaller than the second curvature, so that when the cleaning member 222 is pressed against the outer surface of the ball cover 100 under the action of the supporting member 221, the cleaning member 222 slightly expands and then can be attached to the outer surface of the ball cover 100, so that contact between the cleaning member and the wiper is more reliable, which is beneficial to ensuring the cleaning effect of the ball cover 100.

The cleaning member 222 is pivotally connected to the mounting portion 2213 and is capable of expanding and/or rotating relative to the mounting portion 2213 in response to the second curvature of the spherical cap 100 under the abutment of the mounting portion 2213. The second bending radian mentioned above is the radian of the preset spherical cap 100, and there is often unavoidable manufacturing error during actual processing, and when the error exceeds a certain range, the cleaning effect may not be ensured by the conventional plot assembly. In the present utility model, the first curvature of the cleaning member 222 is set smaller than the second curvature, so that it is ensured that: even if there is a certain error in the ball cover 100, the cleaning member 222 can be reliably attached to the outer surface of the ball cover 100 as long as the error is within a certain range (the manufacturing is not beyond the range), and the cleaning effect is easily ensured.

The mounting portion 2213 is provided with a hinge 223 at an end thereof remote from the limiting portion 2212, and a pivotal connection with the cleaning member 222 is achieved by the hinge 223. Further, a hinge 223 is pivotally connected to the middle portion of the cleaning member 222 along the length direction of the cleaning member 222. In this way, on the premise that the length dimension of the supporting member 221 is fixed, the cleaning member 222 is pivoted to one end of the mounting portion 2213 through the hinge 223, so that the cleaning member 222 can obtain the maximum pressing force, and the cleaning member 222 is reliably attached to the outer surface of the ball cover 100. The center of the cleaning member 222 is pivotally connected to the mounting portion 2213, so that the low pressure can be more uniformly distributed on the cleaning member 222 along the length direction, thereby further improving the cleaning effect.

In addition, in order to shield the camera body and the cleaning assembly 200 in the camera from other structures of the wiper device and the cleaning assembly 200 in the storage position, the camera further includes a decorative cover capable of shielding the cleaning assembly 200 at the outer circumferential side of the ball cover 100.

Referring to fig. 6 and 7, a decorative cover may be provided outside the cleaning assembly 200 below the rotating ring 21 in the figures and attached to the housing 300. In this manner, the trim cover itself may enhance shielding of the cleaning elements 222 in the stowed position, thereby minimizing exposure to sunlight and degradation.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
