The self-cleaning vehicle-mounted camera replaces manual wiping, and the labor intensity of operators is effectively reduced.
In addition, under control system's effect, can clean the camera at any time, effectively guarantee the definition of camera.
The above discloses a specific connection mode of the transmission assembly, and the following describes the working principle of the transmission assembly according to the connection mode of the transmission assembly:
as shown in fig. 6 to 8, a schematic structural diagram of the transmission assembly in different working states is disclosed, wherein fig. 6 is a schematic structural diagram of the transmission assembly in an initial position, fig. 7 is a schematic structural diagram of the transmission assembly in an intermediate position, and fig. 8 is a schematic structural diagram of the transmission assembly in an extreme position.
As shown in fig. 6, in the initial position of the transmission assembly of the present utility model, the sliding groove 41 of the fixing frame 4 is located at the second end of the sliding rod 3, i.e. the end far from the driving assembly. At this point, the second portion of the working arm 1 is in a first position, which is the most distal relative to the drive assembly, and the cleaning cotton 6 wipes the corresponding portion of the camera assembly 7.
When the slide bar 3 does not work, the second portion of the working arm 1 remains horizontal and converges under the camera, so as to avoid the problem of shielding the field of view of the lens 71.
As shown in fig. 7, when the transmission assembly is in the intermediate position, the sliding groove 41 of the fixing frame 4 is located in the intermediate position of the sliding rod 3, namely, is close to the driving assembly relative to the initial position. At this point, the second portion of the working arm 1 is in a second position, which is closer to the drive assembly than the most distal end, and the cleaning cotton 6 wipes the corresponding portion of the camera assembly 7.
As shown in fig. 8, in the extreme position of the transmission assembly of the present utility model, the slide slot 41 of the fixing frame 4 is located at the first end of the slide bar 3, i.e. close to the driving assembly with respect to the intermediate position. At this point, the second portion of the working arm 1 is in a third position, which is closer to the drive assembly than the most distal end, and the cleaning cotton 6 can wipe against the corresponding portion of the camera assembly 7.
When the slide bar 3 is operated to the limit position, the second portion of the working arm 1 is rotated to be in a vertical state.
Referring to fig. 6 to 8, the vehicle-mounted camera of the present utility model can wipe the camera assembly 7 reciprocally under the action of the transmission assembly, so as to realize self-cleaning of the camera assembly 7.
The specific working process is as follows:
when the system monitors that the imaging of the vehicle-mounted camera is unclear, a signal is sent, and the cleaning device is started to start working. After receiving the signal sent by the system, the miniature linear servo steering engine drives the sliding rod 3 to reciprocate left and right, and the working arm 1 starts to reciprocate at a fixed angle under the drive of the sliding rod 3. The rocker 3 is used as an aid to control the rotation direction of the working arm 1, so that the cleaning cotton 6 arranged at the tail end of the working arm 1 can wipe dust on the lens of the camera according to a preset motion track, the lens 71 is kept clean, and the action of automatically wiping the lens 71 is completed. And after the imaging reaches the preset definition, resetting the miniature linear servo steering engine, and stopping wiping.
After the work is completed, the cleaning device is positioned below the vehicle-mounted camera 7, and does not block the field of view of the lens 71.
