[0035] Embodiment 1

[0036] Refer to Figure 1 、 Figure 2 、 Figure 4 The embodiment of the present invention provides a rotary electric lens water removal device, including a lens water removal device main body 100, a sealing cover plate 200 provided at the bottom of the lens water removal device main body, and a glass sheet 300 provided between the lens water removal device main body and the sealing cover plate (a hydrophobic film is also provided on the glass sheet, that is, a hydrophobic coated lens is formed);

[0037] Among them, the lens water removal device main body 100 includes a housing 1, a driving device 2 arranged inside the housing, a rotating shaft sleeve 3, and a supporting device 4; a through hole 11 is provided at the top of the housing 1, and the rotating shaft sleeve 3 is located at the bottom position of the through hole 11 of the housing 1; a glass sheet mounting hole 31 is provided at the center of the rotating shaft sleeve 3, and the glass sheet 300 is connected in the glass sheet mounting hole 31 of the rotating shaft sleeve; the driving device 2 is used to drive the rotating shaft sleeve 3 to rotate, thereby further driving the glass sheet 300 to rotate at high speed together (the structure indicated by the solid lines and shaded lines in the above attachment Figure 1 is the glass sheet 300, and the structure indicated by the grid shaded lines is part of the sealing cover plate 200); and the supporting device 4 is used to support the rotation of the rotating shaft sleeve 3.

[0038] Among them, Figure 1 - Figure 2 is a schematic exploded view of the lens water removal device main body and the sealing cover plate separated in the lens water removal device; Figure 3 is Figure 2 a partial structural schematic diagram of; Figure 4 is a schematic exploded view of the lens water removal device after further completely disassembling the lens water removal device main body, the sealing cover plate, and the glass sheet; Figure 5 is a schematic structural diagram of the rotating shaft sleeve part in the lens water removal device; Figure 6 is a schematic structural diagram of the lens water removal device main body after removing the rotating shaft sleeve in the lens water removal device.

[0039] Analyzing the main structure of the above lens water removal device, it can be seen that the above lens water removal device is mainly composed of a lens water removal device main body, a sealing cover plate, a glass sheet, etc.; at the same time, the water removal device main body mainly includes a housing, a driving device (such as a brushless adjustable speed motor) arranged inside the housing, a rotating shaft sleeve, a supporting device (such as a positioning roller set), etc.

[0040] A through hole is provided at the top of the above housing, and at the same time, the rotating shaft sleeve is located at the bottom position of the through hole of the housing; moreover, a glass sheet mounting hole is provided at the center of the rotating shaft sleeve (the glass sheet can be connected in the glass sheet mounting hole of the rotating shaft sleeve); the above driving device can select various forms of motors, and it can directly drive the rotating shaft sleeve to rotate; and because the glass sheet is sleeved and connected at the center of the rotating shaft sleeve, under the driving action of the driving device, the rotating shaft sleeve and the glass sheet can rotate at high speed together; at the same time, the supporting device supports the rotating shaft sleeve and supports the rotation of the rotating shaft sleeve.

[0041] When the glass sheet rotates at high speed, under the action of centrifugal force, the water droplets on the glass sheet can be thrown off the lens. Even when moving shooting is carried out, the lens water removal device in this embodiment can be fixed in front of the camera lens through an adjustable fixing bracket, and the appropriate rotation speed is adjusted to achieve the real-time anti-rain splash effect.

[0042] The following will give a detailed description of the specific structure and specific technical effects of the lens water removal device provided by the embodiments of the present invention:

[0043] As Figure 4 and Figure 5 shown, the rotating shaft sleeve 3 includes a shaft sleeve body 32 and a groove provided on the outer circumferential wall of the shaft sleeve body, and the groove extends along the outer circumferential wall direction to form an annular groove 33. The above-mentioned rotating shaft sleeve can be sleeved on the glass sheet and drive the glass sheet to rotate together. However, it is the driving device that specifically realizes the rotation of the rotating shaft sleeve.

[0044] Through the unique structural design of the above solution, the camera lens is located in the glass sheet mounting hole of the large-diameter rotating shaft sleeve, and there is no other mechanical structure in front of the glass sheet, which can ensure the water removal effect without interfering with the shooting picture.

[0045] As Figure 3 , Figure 5 and Figure 6 shown, the driving device 2 includes a brushless adjustable-speed motor (not shown in the figure) and a main driving wheel 21. The brushless adjustable-speed motor is used to drive the main driving wheel 21 to rotate, and the main driving wheel 21 is embedded in the annular groove 33 for rotational cooperation.

[0046] In the above solution, the driving device is mainly composed of a motor and a main driving wheel. The motor can drive the main driving wheel to rotate; the motor can be selected in various forms according to needs. However, in the preferred technical solution of this embodiment, the motor can preferably use a brushless adjustable-speed motor, which has the characteristics of high precision, adjustable speed, and large torque. In specific implementation, the brushless adjustable-speed motor is used to drive the main driving wheel to rotate and push the rotating shaft sleeve together with the glass sheet to rotate at a high speed (that is, the brushless adjustable-speed motor can drive the main driving wheel to rotate. The main driving wheel is embedded in the side wall annular groove of the rotating shaft sleeve, and drives the rotating shaft sleeve to rotate together through the friction action. At the same time, a glass sheet is sleeved and installed at the center of the rotating shaft sleeve). In order to ensure the friction between the main driving wheel and the annular groove of the rotating shaft sleeve, an anti-slip sleeve can be sleeved on the outer circumferential wall of the main driving wheel or the outer circumferential wall of the main driving wheel can be designed to be a rough surface.

[0047] As Figure 6 shown, the supporting device 4 includes at least three positioning roller groups 41. The positioning roller groups 41 are connected to the inner side of the housing and are spaced apart along the outer circumferential wall of the shaft sleeve body 32; the positioning roller groups 41 surround the outer circumference of the rotating shaft sleeve 3 to support the rotation of the rotating shaft sleeve 3.

[0048] It should be noted that in the above specific solution, the positioning roller group has at least three, preferably three, five or more; multiple positioning roller groups are fixedly connected to the inner side of the housing and are evenly spaced along the outer circumferential wall of the bushing body, so as to achieve annular support for the rotating bushing; under the action of multiple positioning roller groups, the stability and reliability of the high-speed rotation of the rotating bushing can be ensured. At the same time, it also has the functions of noise reduction and vibration reduction. The positioning roller group is designed with a surrounding layout structure, and at least three groups of positioning roller groups are used to position the rotating bushing.

[0049] As Figure 6 shown, each of the positioning roller groups 41 includes a roller and a mounting rod (not shown in the figure). The mounting rod is fixedly connected to the housing, and the roller is rotationally fitted on the mounting rod; the roller is rotationally fitted in the annular groove.

[0050] At the same time, a bearing is also provided on the mounting rod; the roller freely rotates along the axial direction of the mounting rod through the bearing.

[0051] It should be noted that in the above specific solution, each positioning roller group includes a roller and a mounting rod; the roller is rotationally fitted on the mounting rod, and at the same time, the roller on each positioning roller group should be embedded in the annular groove and form a rotational fit with the rotating bushing. In addition, a bearing is also provided on the mounting rod. On this basis, the roller freely rotates along the axial direction of the mounting rod through the bearing; at the same time, there is a certain gap between the bottom of the housing and the top of the rotating bushing to prevent the rotating bushing from hitting the housing during high-speed rotation.

[0052] As Figure 2 shown, the lens dew removal device main body 100 further includes a vector motor controller 5; the vector motor controller 5 is electrically connected to the brushless adjustable-speed motor; the vector motor controller 5 is used to control the rotation speed of the brushless adjustable-speed motor.

[0053] It should be noted that in the above specific solution, the appropriate motor rotation speed can be adjusted through the vector motor controller according to the rainfall, so as to realize the control of the rotation speed of the brushless adjustable-speed motor. During the implementation of the lens, the rotation speed of the lens is adjusted through the vector motor controller according to the moving speed of the camera and the rainfall. While ensuring the dew removal effect, a large amount of working time is saved.

[0054] As Figure 1As shown in the figure, a chute 12 is provided at the top of the housing 1 near the position of the brushless adjustable-speed motor; the brushless adjustable-speed motor is used to slide within the chute to adjust the tension friction force between the main drive wheel on the brushless adjustable-speed motor and the rotating shaft sleeve. In the above specific solution, the brushless adjustable-speed motor can freely slide within the above chute, so as to adjust the tension friction force (i.e., surface friction force) of the driving wheel on the brushless adjustable-speed motor in the annular groove of the rotating shaft sleeve.

[0055] In addition, for the lens water removal device in the embodiment of the present invention, the waterproof performance of other electrical components should also be considered (that is, a waterproof protection material is covered on the electrical equipment inside the housing, so that it can work stably in the rain environment for a long time). For example, the outside of the vector motor controller can be waterproof sealed using a rainproof and waterproof structure.

[0056] As Figure 1 shown, the main body 100 of the above lens water removal device further includes a power switch 6 and the power interface 7; the power switch 6 and the power interface 7 are arranged at the top position of the housing 1.

[0057] It should be noted that the above power interface can ensure that the lens water removal device obtains an external power supply to meet the power supply requirements for the brushless adjustable-speed motor and the vector motor controller; therefore, it can be said that the power interface can be used to supply power to the brushless adjustable-speed motor and the vector motor controller after connecting to an external power supply. When performing mobile shooting, fix this product in front of the camera lens through an adjustable fixing bracket (the lens extends into the rotating shaft sleeve), turn on the power switch, and adjust the appropriate rotation speed, so as to achieve the real-time effect of preventing rainwater from splashing.

[0058] In the prior art, on rainy days, raindrops will remain on the camera lens, and together with the floating dust particles in the air mixing with the water droplets, the water droplets will get stuck on the lens, causing the image to be blurred. However, by applying the lens water removal device provided by the present invention, the above technical defects can be overcome.

[0059] The lens water removal device provided by the present invention has a reasonable and novel structural design, and can remove water from the glass sheet by driving the glass sheet to rotate at a high speed, and can even eliminate the mixture of water droplets and impurities or even particulate matter on the glass sheet, ensuring the normal use of the inner camera lens.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
