Description

Technical Field

[0001] The present application relates to the field of imaging technology, and in particular to an imaging device and a terminal device. Background Art

[0002] The development of vehicle imaging systems (such as backup cameras and dashcams) and automated driverless vehicles has made automotive imaging devices a crucial component of automotive electronics. Furthermore, unmanned aerial vehicles and underwater vehicles also rely on imaging devices as environmental sensors, leading to their increasing application. However, when vehicles or other mobile vehicles are in motion, imaging device lenses are susceptible to dirt and stains, resulting in poor anti-fouling performance, which can affect their proper function. Summary of the Invention

[0003] In view of the above situation, the present application provides an imaging device that can improve anti-fouling performance.

[0004] An embodiment of the present application provides an imaging device, which includes a lens and a plurality of air ducts. The lens includes a lens, and the lens has an optical axis extending along a first direction. Each air duct includes an air inlet duct and an air outlet duct connected to the air inlet duct. The air inlet duct is configured to let in air. When viewed along the first direction, a plurality of air outlet ducts are arranged on the peripheral side of the lens, and each air outlet duct extends toward the optical axis in a direction perpendicular to the first direction. An air outlet is provided at one end of the air outlet duct away from the air inlet duct, and along the extension direction of the air outlet duct, the projection of the air outlet on the optical axis forms a corresponding axis segment, and the axis segments formed on the optical axis by the plurality of air outlets do not overlap.

[0005] In the above-mentioned imaging device, a plurality of air outlet ducts are arranged around the periphery of the lens, and each air outlet duct extends toward the optical axis in a direction perpendicular to the first direction. An air outlet is provided at one end of the air outlet duct away from the air inlet duct, and the air blown out of the air outlet forms a wind wall in the object side direction of the lens. The wind wall is used to change the trajectory of stains moving toward the lens, so that the stains are away from the lens, reducing the risk of stains adhering to the lens, and thereby improving the anti-fouling performance of the imaging device. Along the extension direction of the air outlet duct, the projection of the air outlet on the optical axis forms a corresponding axis segment, and the wind wall formed by the air outlet passes through the corresponding axis segment. The axis segments formed by the multiple air outlets on the optical axis do not overlap, so that the multiple wind walls are arranged in the first direction in the object side direction of the lens, reducing the risk of wind force cancellation caused by mutual interference between the wind walls formed by the multiple air outlets, which is conducive to increasing the wind force of the wind wall, and thereby improving the anti-fouling performance of the imaging device.

[0006] In some embodiments of the present application, along the first direction, the projection of each air outlet duct and the projection of the lens do not overlap, so as to reduce the risk of the air outlet duct blocking the lens.

[0007] In some embodiments of the present application, a first horizontal plane is defined as being perpendicular to the direction of gravity and tangent to the side of the lens that is lower in the direction of gravity, as viewed along a first direction. Multiple air outlet ducts are located on the side of the first horizontal plane that is tangent to the lens, with the first direction being perpendicular to the direction of gravity. Along the direction of gravity, the ends of the air outlet ducts distal to the air outlet are positioned higher than or flush with the air outlet. This reduces the risk of dirt being trapped in the air duct under the influence of gravity, resulting in a decrease in wind speed. This helps increase the wind force of the wind wall, thereby improving the anti-fouling performance of the imaging device.

[0008] In some embodiments of the present application, when observed along the first direction, the extension direction of each air outlet duct is inclined or perpendicular to the first horizontal plane, so that the stains can be discharged from the air outlet under the action of gravity, further reducing the risk of the stains being accumulated in the air duct under the action of gravity, resulting in a decrease in wind force, which is beneficial to increasing the wind force of the wind wall and thereby improving the anti-fouling performance of the imaging device.

[0009] In some embodiments of the present application, when viewed along the first direction, the angles between the extension directions of two adjacent air outlet pipes are equal, so that multiple wind walls cover the area around the lens, further improving the anti-fouling performance of the imaging device.

[0010] In some embodiments of the present application, each air inlet duct extends along a first direction so as to be arranged around the lens, thereby improving space utilization between the air inlet duct and the lens.

[0011] In some embodiments of the present application, an air inlet is provided at one end of the air inlet pipe away from the air outlet pipe, and the area of ​​the air inlet is larger than the area of ​​the air outlet, so as to enhance the wind pressure of the air blown out of the air outlet, so that the air blown out of the air outlet forms a wind wall in the object side direction of the lens.

[0012] In some embodiments of the present application, the air duct further includes a transition duct, which is connected between the air inlet duct and the air outlet duct. The transition duct is arranged in an arc shape to reduce wind loss caused by air turning in the air duct.

[0013] In some embodiments of the present application, the imaging device further includes a support base, the support base including a mounting portion and a plurality of connecting rods. The mounting portion includes a receiving cavity and a first opening communicating with the receiving cavity, the lens being disposed in the receiving cavity, and the lens being exposed through the first opening. One end of each connecting rod is connected to the mounting portion or to another connecting rod connected to the mounting portion, and each connecting rod is connected to an air inlet duct.

[0014] An embodiment of the present application further provides a terminal device, comprising any imaging device in the above embodiments.

[0015] In the above-mentioned imaging device and terminal device, a plurality of air outlet ducts are arranged on the peripheral side of the lens, and each air outlet duct extends toward the optical axis in a direction perpendicular to the first direction. An air outlet is provided at one end of the air outlet duct away from the air inlet duct, and the air blown out of the air outlet forms a wind wall in the object side direction of the lens. The wind wall is used to change the trajectory of the stains moving toward the lens, so that the stains are away from the lens, reducing the risk of the lens being stained by the stains, and thereby improving the anti-fouling performance of the imaging device. Along the extension direction of the air outlet duct, the projection of the air outlet on the optical axis forms a corresponding axis segment, and the wind wall formed by the air outlet passes through the corresponding axis segment. The axis segments formed by the multiple air outlets on the optical axis do not overlap, so that the multiple wind walls are arranged in the first direction in the object side direction of the lens, reducing the risk of the wind walls formed by the multiple air outlets interfering with each other and causing wind force cancellation, which is conducive to increasing the wind force of the wind wall, and thereby improving the anti-fouling performance of the imaging device.

[0050] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0052] It should be noted that when an element is considered to be “connected” to another element, it may be directly connected to the other element or there may be a centrally disposed element. When an element is considered to be “disposed” on another element, it may be directly disposed on the other element or there may be a centrally disposed element.

[0053] The term "perpendicular" is used to describe the ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular between the two components. For example, combined with numerical descriptions, perpendicular can refer to the angle between two straight lines being in the range of 90°±10°, perpendicular can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicular can also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0056] See also Figure 1 One embodiment of the present application provides an imaging device 100. The imaging device 100 includes a lens 10 and a plurality of air ducts 20. The lens 10 is used to collect light from an object to be photographed. The lens 10 includes a lens 11 having an optical axis L1 extending along a first direction X.

[0057] Each air duct 20 includes an air inlet duct 21 and an air outlet duct 22 connected to the air inlet duct 21. The air inlet duct 21 is configured to receive air. Optionally, the air inlet duct 21 is connected to an external air pump to draw air into the air inlet duct 21 under the pump's blowing action. Alternatively, when the imaging device 100 is moving, the air inlet of the air inlet duct 21 is aligned with the direction of movement of the imaging device 100 to draw air into the air inlet duct 21.

[0058] When viewed along the first direction X, a plurality of air outlet ducts 22 are arranged around the lens 11, and each air outlet duct 22 extends toward the optical axis L1 in a direction perpendicular to the first direction X. Optionally, when viewed along the first direction X, the lens 11 is circular, and the plurality of air outlet ducts 22 are arranged around the lens 11 along the radial direction of the circle.

[0059] Please also refer to Figure 1 and Figure 2An air outlet 221 is provided at one end of the air outlet pipe 22 away from the air inlet pipe 21. The air blown out of the air outlet 221 forms a wind wall 25 in the object side direction of the lens 11. The wind wall 25 is used to change the trajectory of the stains running toward the lens 11, so that the stains are away from the lens 11, reducing the risk of the lens 11 being adhered to the stains, thereby improving the anti-fouling performance of the imaging device 100.

[0060] It should be noted that the stains may be, but are not limited to, dust, rain and mud in the air.

[0061] Please also refer to Figure 2 and Figure 3 Along the extension direction of the air outlet duct 22, the projection of the air outlet 221 onto the optical axis L1 forms a corresponding axial segment L2, and the wind wall 25 formed by the air outlet 221 passes through the corresponding axial segment L2. The axial segments L2 formed by the multiple air outlets 221 on the optical axis L1 do not overlap, so that the multiple wind walls 25 are arranged along the first direction X toward the object side of the lens 11. This reduces the risk of wind walls 25 formed by the multiple air outlets 221 interfering with each other and causing wind force cancellation, thereby increasing the wind force of the wind wall 25 and thereby improving the anti-fouling performance of the imaging device 100.

[0062] Optionally, the axis segments L2 formed by the multiple air outlets 221 on the optical axis L1 are arranged in sequence, or the axis segments L2 formed by the multiple air outlets 221 on the optical axis L1 are arranged at intervals.

[0063] In the imaging device 100 described above, multiple air outlet ducts 22 are arranged around the lens 11. Each air outlet duct 22 extends perpendicular to the first direction X toward the optical axis L1. An air outlet 221 is provided at one end of the air outlet duct 22, distal from the air inlet duct 21. Air blown out of the air outlet 221 forms a wind wall 25 toward the object side of the lens 11. The wind wall 25 is used to redirect dirt traveling toward the lens 11, moving it away from the lens 11, reducing the risk of dirt adhering to the lens 11 and thereby improving the anti-fouling performance of the imaging device 100. Along the extension direction of the air outlet duct 22, the projection of the air outlet 221 onto the optical axis L1 forms a corresponding axial segment L2. The wind wall 25 formed by the air outlet 221 passes through the corresponding axial segment L2. The axis segments L2 formed by the multiple air outlets 221 on the optical axis L1 do not overlap, so that the multiple wind walls 25 are arranged along the first direction X on the object side of the lens 11, reducing the risk of wind force offset caused by mutual interference between the wind walls 25 formed by the multiple air outlets 221, which is beneficial to increasing the wind force of the wind walls 25 and further improving the anti-fouling performance of the imaging device 100.

[0064] Please also refer to Figure 4 In some embodiments, along the first direction X, the projection of each air outlet duct 22 and the projection of the lens 11 do not overlap, so as to reduce the risk of the air outlet duct 22 blocking the lens 11 .

[0065] In some embodiments, as viewed along a first direction X, a first horizontal plane A is defined as being perpendicular to the direction of gravity Z and tangent to the lower side of the lens 11 in the direction of gravity Z. Multiple air outlet ducts 22 are located on the side of the first horizontal plane A that is tangent to the lens 11, with the first direction X being perpendicular to the direction of gravity Z. Along the direction of gravity Z, the ends of the air outlet ducts 22 distal from the air outlet 221 are positioned higher than or flush with the air outlet 221. This reduces the risk of dirt being trapped in the air duct under the action of gravity, resulting in a decrease in wind speed. This helps increase the wind speed of the wind wall 25, thereby enhancing the anti-fouling performance of the imaging device 100.

[0066] It is understandable that in other embodiments, a plurality of air outlet pipes 22 are arranged around the periphery of the lens 11 .

[0067] Please continue reading Figure 4 In some embodiments, when observed along the first direction X, the extension direction of each air outlet duct 22 is inclined or perpendicular to the first horizontal plane A, so that the stains can be discharged from the air outlet 221 under the action of gravity, further reducing the risk of the stains being accumulated in the air duct under the action of gravity and causing the wind force to drop, which is beneficial to increasing the wind force of the wind wall 25 and further improving the anti-fouling performance of the imaging device 100.

[0068] In some embodiments, when viewed along the first direction X, the angles between the extension directions of two adjacent air outlet pipes 22 are equal, so that the multiple air walls 25 cover the area around the lens 11, further improving the anti-fouling performance of the imaging device 100.

[0069] Please also refer to Figure 1 and Figure 5 In some embodiments, each air inlet duct 21 extends along the first direction X so as to be disposed around the lens 10 , thereby improving space utilization between the air inlet duct 20 and the lens 10 .

[0070] It is understandable that, in other embodiments, the air inlet pipe 21 may be bent so that the air inlet of the air inlet pipe 21 is consistent with the moving direction of the imaging device 100 , so as to guide air into the air inlet pipe 21 .

[0071] In some embodiments, an air inlet 211 is provided at one end of the air inlet duct 21 away from the air outlet duct 22. The area of ​​the air inlet 211 is larger than the area of ​​the air outlet 221. The amount of air flowing in from the air inlet 211 is equal to the amount of air blown out from the air outlet 221. The air will be accelerated in the air duct 20 to enhance the wind pressure of the air blown out from the air outlet 221, so that the air blown out from the air outlet 221 forms a wind wall 25 in the object side direction of the lens 11.

[0072] Optionally, the air inlet 211 is connected to an external air pump; or the air inlet of the air inlet pipe 21 is consistent with the moving direction of the imaging device 100 .

[0073] In some embodiments, the air outlet 221 is rectangular in shape. When viewed along the first direction X, the length of the rectangle is greater than or equal to the width of the lens 11 , so that the wind wall 25 formed by the air outlet 221 covers the lens 11 .

[0074] Please also refer to Figure 5 and Figure 6 In some embodiments, the air duct 20 further includes a transition duct 23 , which is connected between the air inlet duct 21 and the air outlet duct 22 . The transition duct 23 is arranged in an arc shape to reduce wind loss caused by the turning of air in the air duct 20 .

[0075] Please also refer to Figure 1 and Figure 7 In some embodiments, the imaging device 100 further includes a support base 30. The support base 30 includes a mounting portion 31 and a plurality of connecting rods 32. The mounting portion 31 defines a housing cavity 311 and a first opening 312 communicating with the housing cavity 311. The lens 10 is disposed within the housing cavity 311, and the lens 11 is exposed through the first opening 312. One end of each connecting rod 32 is connected to the mounting portion 31 or to another connecting rod 32 connected to the mounting portion 31. The other end of each connecting rod 32 is connected to an air inlet duct 21 to improve the positional stability between the lens 10 and the air duct 20.

[0076] In some embodiments, the mounting portion 31 includes two mounting plates 313 and a connector 314 connected between the two mounting plates 313. The two mounting plates 313 are spaced apart along the second direction Y. A receiving cavity 311 is formed between the two mounting plates 313. The lens 10 is clamped between the two mounting plates 313. One end of the two mounting plates 313 forms a first opening 312. The first direction X, the direction of gravity Z, and the second direction Y are perpendicular to each other.

[0077] In some embodiments, the connecting member 314 includes two mutually hinged connecting plates 315 and an elastic member 316, each connecting plate 315 is connected to a mounting plate 313, the elastic member 316 is connected between the two connecting plates 315, and drives the two mounting plates 313 to elastically clamp the lens 10 through the two connecting plates 315, so as to improve the stability of the connection between the lens 10 and the support seat 30.

[0081] When viewed along the first direction X, the air outlet duct 22 of the first air duct 20a and the air outlet duct 22 of the fifth air duct 20e are respectively adjacent to the first horizontal plane A, and the air outlet duct 22 of the second air duct 20b, the air outlet duct 22 of the third air duct 20c, and the air outlet duct 22 of the fourth air duct 20d are sequentially arranged between the air outlet duct 22 of the first air duct 20a and the air outlet duct 22 of the fifth air duct 20e.

[0082] Please also refer to Figure 4 The extension direction of the outlet duct 22 of the first air duct 20a forms an angle α with the first horizontal plane A, so that the end of the outlet duct 22 of the first air duct 20a away from the air outlet 221 is higher than the air outlet 221. The extension direction of the outlet duct 22 of the fifth air duct 20e forms an angle θ with the first horizontal plane A, so that the end of the outlet duct 22 of the fifth air duct 20e away from the air outlet 221 is higher than the air outlet 221. When viewed along the first direction X, the angles between the extension directions of two adjacent outlet ducts 22 are equal and are both (180° - α - θ) * 20%.

[0083] Optionally, α may be 5°, 10°, 15°, 20°, 15°, or 30°; and θ may be 5°, 10°, 15°, 20°, 15°, or 30°.
