Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a self-cleaning protection device for an outdoor camera. Background Art

[0002] Cameras installed outdoors or on the road are often contaminated by natural factors, which affects the clarity of the camera. In the related art, the contaminants on the camera lens are usually cleaned manually on a regular basis to improve the clarity of the camera. However, the daily regular manual cleaning operation is difficult and the cleaning cycle is long, resulting in low cleaning efficiency of the camera lens.

[0003] To this end, the Chinese patent application with the publication number "CN112929548A" has published "a self-cleaning protective device for a camera", whose main structure includes a housing assembly, a cleaning assembly and a driving member. The cleaning assembly includes a round lens, an active ring, a driven ring and two wipers. The round lens and the active ring are rotatably inserted in the cavity, the driven ring is coaxially sleeved on the outer peripheral wall of the round lens, the active ring and the driven ring are transmission-coordinated to drive the driven ring to rotate, one wiper is installed on the inner wall of the box body, and the other wiper is installed on the plate surface of the box cover facing the box body. The self-cleaning protective device can automatically clean the camera lens and improve the cleaning efficiency of the camera lens.

[0004] In the actual cleaning process of the lens part, the self-cleaning protection device for the camera utilizes a rotating wiper to scrape off the dirt on the surface of the circular lens. However, the pressure between the contact surface of the wiper and the lens cannot be guaranteed, resulting in it being able to only scrape off some dirt with a low degree of adhesion. For dirt with a high degree of adhesion, since it is impossible to ensure the pressure between the contact surface of the wiper and the lens, the effective cleaning effect will be relatively poor.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 , Figure 2 and Figure 3 A self-cleaning protection device for an outdoor camera comprises a component fixing sleeve 1, a motor fixing cavity 2 and a component fixing cavity 3 arranged in an upper and lower layout inside the component fixing sleeve 1, a No. 1 component fixing groove 4 arranged on the top of the component fixing sleeve 1, a driving motor 8 fixedly installed in the motor fixing cavity 2, and a main pulley 6 installed at the end of a rotor 5 of the driving motor 8. A fixing plate structure 112 is fixedly installed near the camera, and when the camera is operated to a non-monitoring viewing angle, the lens and the brush strip 1010 are just in an opposing state. At the same time, a water pump drain port and a No. 1 liquid flow hole 94 are connected through a flexible pipe.

[0031] In order to use the pressure of liquid to achieve the expansion and contraction function, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set up a hydraulic telescopic transmission mechanism 9, which is provided with a first transverse hollow shell 91 installed in the component fixed cavity 3 through a bearing and can rotate with the main pulley 6 through a belt 7, and a hollow telescopic rod 98 telescopically placed inside the first transverse hollow shell 91 and can rotate with the first transverse hollow shell 91. The liquid used for cleaning enters the first component active cavity 93 from the first liquid flow hole 94 and continues to flow through the second liquid flow hole 99. The end of the second liquid flow hole 99 is blocked by the valve plate 1011. Therefore, the liquid pressure will act on The contact end surface of the piston plate 97 forms pressure on the piston plate 97, and the pressure causes the piston plate 97 to move and compress the No. 1 coil spring 910. At the same time, the hollow telescopic rod 98 extends to drive the brush strip 1010 to move toward the lens until the brush strip 1010 contacts the surface of the lens. Then the drive motor 8 is started, and the rotor 5 indirectly drives the No. 1 horizontal hollow shell 91 to rotate, and the rotation drives the brush strip 1010 to rotate, thereby wiping the lens. The pressure of the liquid can be used to realize the telescopic contact function to provide the pressure required for wiping.

[0032] For the specific structure of the hydraulic telescopic transmission mechanism 9, please refer to Figure 4, including a No. 1 transverse hollow shell 91 rotatably mounted in the component fixing cavity 3 through a bearing, the outer circumferential surface of the No. 1 transverse hollow shell 91 is provided with a secondary pulley 92 which is an integral structure with it and is linked with the main pulley 6 through a belt 7, a No. 1 raised column structure 95 which is an integral structure with it is provided at the center of one end of the No. 1 transverse hollow shell 91, a No. 1 component active cavity 93 is provided inside the No. 1 transverse hollow shell 91, the other end surface of the No. 1 transverse hollow shell 91 is provided with a No. 1 liquid flow hole 94 which is an integral structure with it and connected to the corresponding end of the No. 1 component active cavity 93, the other end of the No. 1 transverse hollow shell 91 is provided with a No. 1 raised column structure 95 which is an integral structure with it, the interior of the No. 1 raised column structure 95 is provided with a No. 1 rod body through hole 96 which is connected to the external space and the No. 1 component active cavity 93, the No. 1 transverse hollow shell 91 is provided with a piston plate 97 which can move axially along the No. 1 component active cavity 93, and the piston plate 9 A hollow telescopic rod 98 is provided on the end surface facing the No. 1 rod body through-hole 96, which is an integral structure with the rod body through-hole 96 and passes through the No. 1 rod body through-hole 96. In order to realize the transmission function of the rotation phenomenon, it is necessary to make the structural shape of the cross section of the No. 1 rod body through-hole 96 consistent with the structural shape of the cross section of the hollow telescopic rod 98, both of which are polygonal structures, and the structural size of the cross section of the No. 1 rod body through-hole 96 matches the structural size of the cross section of the hollow telescopic rod 98. The hollow telescopic rod 98 is sleeved with a No. 1 coil spring 910 on the outer periphery of the rod body located inside the No. 1 component active cavity 93. In order to provide an elastic reset function, it is necessary to make one end of the No. 1 coil spring 910 abut against the end surface of the No. 1 component active cavity 93 close to the No. 1 protruding column structure 95, and the other end abuts against the corresponding end surface of the piston plate 97, and the initial length of the No. 1 coil spring 910 is greater than the length of the No. 1 component active cavity 93. The piston plate 97 and the hollow telescopic rod 98 are provided with a No. 2 liquid flow hole 99 with both ends in an open state.

[0033] In order to use the liquid pressure in stages and thus improve the effective utilization of the liquid pressure, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6, it is necessary to set up a pressure-controlled cleaning mechanism 10, which is provided with a second horizontal hollow shell 101 that can rotate with the hollow telescopic rod 98 and can spray water to one end, a valve plate 1011 placed inside the second horizontal hollow shell 101 and producing an elastic damping effect on the water flow from the inside of the hollow telescopic rod 98, and a brush strip 1010 that can produce a rotating cleaning function on the conflicting part. When the liquid exerts a force on the valve plate 1011, and the force is less than the elastic strength of the second coil spring 1015, the liquid will form pressure in the active cavity 93 of the first component, and the pressure will indirectly cause the hollow telescopic rod 98 to extend, driving the brush strip 1010 to the lens. Move until the brush strip 1010 contacts the surface of the lens. This part of the liquid pressure can realize the telescopic contact function of the lens. When the pressure continues to increase and is greater than the elastic strength of the No. 2 coil spring 1015, the valve plate 1011 will move in a directional manner. Of course, when the No. 2 coil spring 1015 is compressed, the pressure formed by the liquid pressure needs to ensure that it will not damage the camera and the lens of the camera. This can be done by controlling the elastic strength of the No. 2 coil spring 1015. At this time, the liquid continues to flow and is sprayed toward the lens through the liquid spray hole 107. This part of the liquid pressure realizes the flushing function of the lens, thereby improving the effective utilization of the liquid pressure.

[0034] For the specific structure of the pressure-controlled cleaning mechanism 10, please refer to Figure 5 and Figure 6, comprising a second transverse hollow shell 101, one end surface of the second transverse hollow shell 101 is provided with a second protruding column structure 102 which is an integral structure therewith, the other end surface of the second transverse hollow shell 101 is provided with a third protruding column structure 103 which is an integral structure therewith, the interior of the second transverse hollow shell 101 is provided with a second component active cavity 104, the interior of the third protruding column structure 103 is provided with a third liquid flow hole 105 which is connected to the corresponding end of the second component active cavity 104, the interior of the third protruding column structure 103 is provided with a second component which is connected to the third liquid flow hole 105 and the external space The second component fixing groove 106 is provided with a strip embedded body 108 having an integral structure therewith at the end center of the second raised column structure 102, and a strip embedded groove 109 having an inner concave structure is provided at one end of the strip embedded body 108, and a brush strip 1010 is embedded in the strip embedded groove 109 of the strip embedded body 108, and the brush strip 1010 protrudes outwardly relative to the strip embedded groove 109, and the interior of the second raised column structure 102 is provided with two symmetrically arranged strip embedded grooves 109 and connected to the outside air. The second horizontal hollow shell 101 is provided with a valve plate 1011 capable of axial movement along the second component active cavity 104, and the circumferential part of the valve plate 1011 is provided with a plurality of liquid flow grooves 1012 with a concave structure. The end face of the valve plate 1011 facing the third liquid flow hole 105 is provided with an annular embedded groove 1013 with a concave structure. The valve plate 1011 is embedded with a rubber sealing ring 1014 inside the annular embedded groove 1013. In order to achieve the sealing of the liquid, In order to realize the closing function, it is necessary to make the structural radius of the inner ring of the rubber sealing ring 1014 larger than the structural radius of the No. 3 liquid flow hole 105, the structural radius of the outer ring of the rubber sealing ring 1014 is smaller than the distance between the axial line of the liquid flow groove 1012 and the valve plate 1011, and the thickness of the rubber sealing ring 1014 is larger than the depth of the annular embedded groove 1013. A No. 2 coil spring 1015 in a compressed state is placed on the other end face of the valve plate 1011. In order to form a pressure difference of the liquid, it is necessary to make the elastic strength of the No. 2 coil spring 1015 larger than the elastic strength of the No. 1 coil spring 910.

[0035] To adjust the angle of the device, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8, it is necessary to set up a ball-hinged connection mechanism 11, which is provided with a hemispherical shell 111 that can be fixedly installed on a fixed base surface, a ball head 115 rotatably placed inside the hemispherical shell 111 and capable of driving the component fixing sleeve 1 to move, and a hemispherical rubber pad 116 embedded between the hemispherical shell 111 and the ball head 115 and using the friction force formed by itself in a compressed state to keep the hemispherical shell 111 and the ball head 115 stationary without external force. The fixed plate structure 112 is fixedly installed near the camera, and then the component fixing sleeve 1 is rotated to adjust the angle. After adjustment, when the camera moves to a non-monitoring viewing angle, the lens and the brush strip 1010 are just in an opposing state.

[0036] For the specific structure of the hemispherical housing 111, please refer to Figure 7 and Figure 8 A No. 5 raised column structure 118 is provided in the middle of the spherical surface, and a fixed plate structure 112 is provided at the top of the No. 5 raised column structure 118, and a No. 1 hemispherical cavity 113 with a concave structure is provided inside the hemispherical shell 111. A hemispherical embedding groove 114 with a concave structure is provided on the periphery of the hemispherical shell 111 located in the middle area of ​​the No. 1 hemispherical cavity 113. A hemispherical rubber pad 116 is embedded in the hemispherical embedding groove 114 of the hemispherical shell 111, and a No. 2 hemispherical cavity is provided inside the hemispherical rubber pad 116. 119, the hemispherical shell 111 and the hemispherical rubber pad 116 are provided with a rotatable ball head 115 inside the No. 1 hemispherical cavity 113 and the No. 2 hemispherical cavity 119. In order to realize the rotational connection relationship, it is necessary to make the structural radius of the No. 1 hemispherical cavity 113 match the structural radius of the ball head 115, and the depth of the No. 1 hemispherical cavity 113 is greater than the structural radius of the ball head 115 and smaller than the structural diameter of the ball head 115. The bottom of the spherical surface of the ball head 115 is provided with a No. 4 raised column structure 117 which is an integral structure with it and fixedly installed inside the No. 1 component fixing groove 4.

[0037] The specific working principle of the present invention is to fix the fixing plate structure 112 near the camera, and then rotate the component fixing sleeve 1 to adjust the angle. After the adjustment, when the camera is operated to a non-monitoring viewing angle, the lens and the brush strip 1010 are just in an opposing state. At the same time, the drainage port of a water pump and the No. 1 liquid flow hole 94 are connected through a flexible pipe.

[0038] When cleaning is required, the camera is controlled so that when the camera moves to a non-monitoring viewing angle, the lens and the brush strip 1010 are exactly in an opposing state, and then the water pump and the drive motor 8 are started, wherein the suction port of the water pump needs to be in the cleaning liquid. When the water pump is driven, the cleaning liquid enters the interior of the active cavity 93 of the No. 1 component from the No. 1 liquid flow hole 94, and continues to flow through the No. 2 liquid flow hole 99. When the liquid exerts a force on the valve plate 1011, and the force is less than the elastic strength of the No. 2 coil spring 1015, the liquid will form pressure in the active cavity 93 of the No. 1 component, and the pressure will indirectly cause the hollow telescopic rod 98 to extend, driving the brush strip 1010 to move toward the lens until the brush strip 1010 hits the surface of the lens;

[0039] At the same time, under the influence of the driving motor 8, the rotor 5 will indirectly drive the first horizontal hollow shell 91 to rotate, and this rotation will drive the brush strip 1010 to rotate, so as to wipe the lens, and then the telescopic resistance function can be realized by using the pressure of the liquid;

[0040] At the same time, when the pressure continues to increase and is greater than the elastic strength of the No. 2 coil spring 1015, the valve plate 1011 will be moved in a directional manner. Of course, when the No. 2 coil spring 1015 is compressed, the pressure formed by the liquid pressure needs to ensure that it will not damage the camera and the lens of the camera. This can be done by controlling the elastic strength of the No. 2 coil spring 1015. At this time, the liquid continues to flow and is sprayed toward the lens through the liquid spray hole 107. This part of the liquid pressure realizes the function of flushing the lens.

[0041] When cleaning is completed, the water pump and the drive motor 8 are turned off, and under the elastic reset ability of the No. 1 coil spring 910 and the No. 2 coil spring 1015, the parts in contact with them will be reset to the initial state.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
