Abstract
Description
Technical Field
[0001] The present application relates to the field of optical imaging technology, and in particular to a vehicle-mounted lens and a vehicle. Background Art
[0002] In recent years, on-board cameras are widely installed on vehicles, which can capture, obtain and record real-time images around or inside the vehicle. The images taken by on-board cameras can be applied to functions such as automatic braking and automatic driving. On-board cameras not only improve driving safety, but also enable cars to achieve more functions.
[0003] Generally, a vehicle-mounted lens includes a lens that can be used to focus light and control the light beam passing through the lens.
[0004] However, due to the temperature difference between the lens of the vehicle-mounted lens and the surrounding environment, when the temperature of the lens is lower than the temperature of the surrounding environment, the lens of the vehicle-mounted lens is prone to frost and fog, which prevents the vehicle-mounted lens from clearly imaging. Utility Model Content
[0005] The embodiments of the present application provide a vehicle-mounted lens and a vehicle, which can solve the problem that the lens is easily frosted and fogged.
[0006] In order to achieve the above objectives, the embodiments of the present application adopt the following technical solutions:
[0007] In a first aspect, an embodiment of the present application provides a vehicle-mounted lens, which includes a lens barrel, a heating element, and a lens. The lens barrel has a first end face, and the first end face is provided with a mounting hole, and the hole wall of the mounting hole includes an annular first hole wall. The heating element is annular and abuts against the first hole wall. The lens is arranged in the mounting hole, and the peripheral wall of the lens includes an annular first peripheral wall, and the first peripheral wall is in contact with a side of the heating element away from the first hole wall. The first peripheral wall is inclined, and the outline size of the first peripheral wall close to the first end face is greater than the outline size of the first peripheral wall away from the first end face.
[0008] In the vehicle-mounted lens provided in the embodiment of the present application, when there is a temperature difference between the lens of the vehicle-mounted lens and the surrounding environment, and the temperature of the lens is lower than the temperature of the surrounding environment, the heating element can heat the lens because the heating element is attached to the first peripheral wall of the lens. The heat provided by the heating element can be transferred to the first peripheral wall of the lens, thereby increasing the temperature of the lens, achieving the effect of heating, defoggering and defrosting.
[0009] Since the first circumferential wall is inclined and the contour dimension of the first circumferential wall close to the first end face is larger than the contour dimension of the first circumferential wall away from the first end face, the heating direction of the lens by the heating element is inclined upward, and the heating direction is toward the working area of the lens, which can make the working area of the lens heat up faster and achieve the effect of heating, defoggering and defrosting more quickly.
[0010] In some embodiments, the included angle between the first peripheral wall and the first end surface is less than or equal to 60° and greater than or equal to 30°.
[0011] In some embodiments, the first hole wall is provided with an avoidance hole, and the vehicle-mounted lens further comprises a heating harness which is electrically connected to the heating element and is passed through the avoidance hole.
[0012] In some embodiments, the hole wall of the mounting hole further includes a second hole wall and a third hole wall. The second hole wall is annular, located at the periphery of the first hole wall, one end of which is connected to an end of the first hole wall close to the first end face, and the second hole wall is parallel to the first end face. The third hole wall is annular, located at the periphery of the second hole wall, one end of which is connected to an end of the second hole wall away from the first hole wall, and the other end of which is connected to the first end face. The peripheral wall of the lens is formed with an overlap portion, which overlaps the second hole wall and fits the second hole wall and the third hole wall.
[0013] In some embodiments, the second hole wall is provided with an avoidance groove, which is arranged around the periphery of the first hole wall. The vehicle-mounted lens further comprises a waterproof ring, which is annular and arranged in the avoidance groove and abuts against the overlap portion.
[0014] In some embodiments, the hole wall of the mounting hole further includes a fourth hole wall. The fourth hole wall is annular, located on the inner side of the first hole wall, and one end is connected to an end of the first hole wall away from the first end face. The fourth hole wall is parallel to the first end face, and a portion of the peripheral wall of the lens is in contact with the fourth hole wall.
[0015] In some embodiments, the vehicle-mounted lens further comprises a pressing ring, which is sleeved on the periphery of the lens barrel and partially located on the side where the first end surface is located, and arranged opposite to the mounting hole. At least a portion of the pressing ring abuts against the lens.
[0016] In some embodiments, the second hole wall and the third hole wall are perpendicular to each other.
[0017] In some embodiments, the heating element is a FPC heater or a heating film.
[0018] In a second aspect, an embodiment of the present application further provides a vehicle, comprising any of the above-mentioned vehicle-mounted lenses.
[0019] Since the vehicle provided in the embodiment of the present application includes any of the above-mentioned vehicle-mounted lenses, the beneficial effects that can be produced by the vehicle are the same as the beneficial effects of the above-mentioned vehicle-mounted lenses, which will not be repeated here.

DETAILED DESCRIPTION
[0026] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.
[0027] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.
[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] With the improvement of people's living standards, cars are used more and more frequently in people's daily lives and have gradually become one of the important means of transportation for people. At the same time, as people's requirements for cars are getting higher and higher, the automobile industry is developing rapidly. Automobile manufacturers need to consider not only the high-end performance of the vehicle itself, but also the safety of the vehicle.
[0031] The embodiment of the present application provides a vehicle, which may include an engine, a chassis, and a body. It is understandable that the vehicle may be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc., and the specific type of the vehicle is not specifically limited here.
[0032] Among them, the engine is the power device of the vehicle, which can provide power for the vehicle to move on the ground.
[0033] The chassis can be used to install the engine and other components and assemblies of the vehicle to form the overall shape of the vehicle, and receive the power of the engine to make the vehicle move and ensure normal driving.
[0034] The vehicle body can be mounted on the chassis, and a cabin is formed inside, which can be used for the driver, passengers or cargo. It should be noted that when the vehicle is a bus or a car, its body is generally an integral structure. When the vehicle is a truck, its body is generally composed of a cab and a cargo box.
[0035] In addition, in order to enrich the functions of the vehicle, the vehicle provided in the embodiment of the present application may further include a vehicle-mounted camera, which can capture, obtain, and record real-time images around or inside the vehicle.
[0036] Images captured by on-board cameras can be used in functions such as automatic braking and automatic driving. On-board cameras not only improve driving safety, but also enable cars to achieve more functions.
[0037] By installing on-board cameras in different positions of the vehicle, such as the front, rear, side and surround view, the driver can be provided with real-time road condition information, such as forward collision warning, lane keeping assist, blind spot monitoring, reversing images, etc., to ensure the safety of the driver and passengers.
[0038] For example, the camera of a driving recorder can record the situation in front of and inside the vehicle, which can serve as important evidence in determining accident responsibility.
[0039] In the related art, a vehicle-mounted lens includes a lens, which can be used to focus light and control the light beam passing through the lens.
[0040] However, there is a temperature difference between the lens of the vehicle-mounted lens and the surrounding environment. When the temperature difference is too large and the temperature of the lens is lower than the temperature of the surrounding environment, hot moisture will condense when it contacts the colder lens surface, causing the lens of the vehicle-mounted lens to easily frost and fog, hindering the clear imaging of the vehicle-mounted lens. In this way, the lens field of view of the vehicle-mounted lens is blocked, the imaging function and shooting function are reduced, and in severe cases, it may even cause component failure and machine damage.
[0041] The decline in the imaging and shooting functions of the vehicle-mounted lens will prevent the driver from obtaining timely and clear information about the vehicle's surroundings, and cannot ensure the safety of the driver and passengers.
[0042] Based on this, Figure 1 As shown, Figure 1 The schematic diagram of the structure of a vehicle-mounted lens 100 provided in an embodiment of the present application. The vehicle-mounted lens 100 may include a lens barrel 1. The lens barrel 1 may be used to connect and accommodate a lens assembly, and may protect the lens assembly.
[0043] See also Figure 2 and Figure 3 , Figure 2 This is an exploded view of the structure of a vehicle-mounted lens 100 provided in an embodiment of the present application. Figure 3 The cross-sectional view of a vehicle-mounted lens 100 provided in an embodiment of the present application is shown in FIG. The lens barrel 1 has a first end surface 11 , and a mounting hole 111 is formed on the first end surface 11 . The hole wall 1111 of the mounting hole 111 includes an annular first hole wall 11111 .
[0044] The vehicle-mounted lens 100 may further include a heating element 2, which is annular and abuts against the first hole wall 11111. The heating element 2 may heat the surrounding objects or environment. The first hole wall 11111 may provide bearing and support for the heating element 2.
[0045] The vehicle-mounted lens 100 may further include a lens 3, which is disposed in the mounting hole 111. The peripheral wall 31 of the lens 3 includes an annular first peripheral wall 311, and the first peripheral wall 311 is in contact with a side of the heating element 2 away from the first hole wall 11111. The lens 3 can be used to focus light and control the light beam passing through the lens 3.
[0046] When there is a temperature difference between the lens 3 of the vehicle-mounted lens 100 and the surrounding environment, and the temperature of the lens 3 is lower than the temperature of the surrounding environment, the heating element 2 can heat the lens 3 because the heating element 2 is in contact with the first peripheral wall 311 of the lens 3. The heat provided by the heating element 2 can be transferred to the first peripheral wall 311 of the lens 3, thereby increasing the temperature of the lens 3, achieving the effect of heating, defogger and defrost.
[0047] It should be noted that the present application does not limit the type of the heating element 2, and the type can be selected according to actual conditions.
[0048] Exemplarily, the heating element 2 may be a flexible printed circuit (FPC) heater. It is understood that the FPC heater may include an FPC and a heating device. The heating device is disposed on the FPC to generate heat under the power supply of the PFC.
[0049] The FPC heater can be customized according to the curvature of the first peripheral wall 311 of the lens 3, and can be closely attached to the surface of the first peripheral wall 311 of the lens 3, saving limited space resources. At the same time, since the FPC heater can be closely attached to the surface of the first peripheral wall 311 of the lens 3, it can provide uniform and efficient heat conduction, ensuring that the entire lens 3 is quickly and evenly heated, reducing the frost and fogging of the lens 3 caused by temperature difference, and ensuring clear imaging of the vehicle-mounted lens 100.
[0050] Exemplarily, the heating element 2 may also be a heating film, wherein the heating film is a thin heating element that converts electrical energy into thermal energy.
[0051] The heating film can generate heat quickly, ensuring that the entire lens 3 heats up quickly, reducing the frost and fogging of the lens 3 caused by temperature difference, and ensuring clear imaging of the vehicle lens 100. In addition, due to the good flexibility and lightweight characteristics of the heating film, the heating film can fit the curved surface structure of the lens 3 tightly without adding extra volume and weight, meeting the compact design requirements of the automotive industry.
[0052] Understandably, Figure 2 The heating element 2 shown may be placed against Figure 3 As shown in the first hole wall 11111. However, as mentioned above, the heating element 2 can be a thin sheet as a whole, so Figure 3 The heating element 2 is not shown.
[0053] See also Figure 2 and Figure 3 The first peripheral wall 311 can be tilted, and the outline dimension of the first peripheral wall 311 close to the first end surface 11 is larger than the outline dimension of the first peripheral wall 311 away from the first end surface 11.
[0054] See also Figure 4 , Figure 4 This is a partial enlarged view of a vehicle-mounted lens 100 provided in an embodiment of the present application. For example, the lens 3 is generally hemispherical in shape. Figure 4 The α region is the region where light passes, and the β region is the region where light does not pass. It can be seen that the α region is the working region of the lens 3, and the β region is the non-working region of the lens 3.
[0055] Since the first circumferential wall 311 is inclined, and the contour dimension of the first circumferential wall 311 close to the first end face 11 is larger than the contour dimension of the first circumferential wall 311 away from the first end face 11, the heating direction of the lens 3 by the heating element 2 is inclined upward, and the heating direction is toward the working area of the lens 3, which can make the working area of the lens 3 heat up faster and achieve the effect of heating, defoggering and defrosting more quickly.
[0056] In addition, at the same height, the area of the inclined first circumferential wall 311 is larger than that of the horizontally set area, and the contact area between the first circumferential wall 311 and the heating element 2 is larger, which can make the first circumferential wall 311 heated more evenly, further improve the heating speed of the lens 3, and achieve the heating, defog and defrosting effects more quickly.
[0057] By tilting the lens 3, the non-working area can be reduced, and the working area of the lens 3 can be heated up faster, achieving the effect of heating, defoggering and defrosting faster. In this way, the vehicle-mounted lens 100 can image more quickly and clearly, and the driver can obtain information about the vehicle's surrounding environment through the vehicle-mounted lens 100 in a timely and clear manner, thereby improving the safety factor of the driver and passengers.
[0058] In some embodiments, the included angle between the first peripheral wall 311 and the first end surface 11 is less than or equal to 60° and greater than or equal to 30°.
[0059] When the angle between the first peripheral wall 311 and the first end face 11 is less than or equal to 60° and greater than or equal to 30°, the heating element 2 can be better oriented toward the working area of the lens 3, so that the working area of the lens 3 can be heated up faster, and the effects of heating, defoggering and defrosting can be achieved more quickly.
[0060] At the same height, the contact area between the heating element 2 and the first peripheral wall 311 of the lens 3 is larger, so that the working area of the lens 3 can be heated up faster, and the effects of heating, defog and defrosting can be achieved more quickly.
[0061] It is understandable that the angle between the first peripheral wall 311 and the first end face 11 can be selected according to actual conditions. For example, the angle between the first peripheral wall 311 and the first end face 11 can be 30°, 40°, 45°, 50°, or 60°.
[0062] Of course, in other embodiments, the angle between the first peripheral wall 311 and the first end face 11 may be greater than 0° and less than 30°. Alternatively, in other embodiments, the angle between the first peripheral wall 311 and the first end face 11 may be greater than 60° and less than 90°.
[0063] In some embodiments, the first hole wall 11111 may also be provided with an avoidance hole (not shown in the figure). Figure 2The vehicle-mounted lens 100 may further include a heating harness 4. The heating harness 4 is electrically connected to the heating element 2, and the heating harness 4 is passed through the avoidance hole. The heating harness 4 can transmit electrical energy to the heating element 2.
[0064] In this way, the heating harness 4 is inside the vehicle-mounted lens 100 , further ensuring that the heating element 2 can work safely and stably.
[0065] As can be seen from the above, the heating harness 4 is passed through the avoidance hole of the lens barrel 1, the heating element 2 is located between the lens barrel 1 and the lens 3, and the heating harness 4 and the heating element 2 are both inside the vehicle-mounted lens 100. Since the interior of the vehicle-mounted lens 100 has reached the waterproof and dustproof standards, there is no need to add additional waterproof and dustproof components to protect the heating harness 4 and the heating element 2, which simplifies the production process, has a simple structure, and is easy to implement.
[0066] It should be noted that the embodiment of the present application does not limit the material used for the heating harness 4, and the material can be selected according to actual conditions.
[0067] For example, the heating harness 4 may be made of FEP. Since FEP has the advantages of high temperature resistance and good chemical stability, it can improve the stability and safety of the vehicle lens 100 and extend the service life of the vehicle lens 100.
[0068] For example, the heating harness 4 may be made of polytetrafluoroethylene. Since polytetrafluoroethylene has the characteristics of high temperature resistance and good chemical stability, it can improve the stability and safety of the vehicle lens 100 and extend the service life of the vehicle lens 100.
[0069] In some embodiments, see Figure 3 The hole wall 1111 of the mounting hole 111 may further include a second hole wall 11112 and a third hole wall 11113. The second hole wall 11112 is annular and is located at the periphery of the first hole wall 11111. One end of the second hole wall 11112 is connected to one end of the first hole wall 11111 close to the first end face 11. The second hole wall 11112 is parallel to the first end face 11.
[0070] The third hole wall 11113 is annular and is located at the periphery of the second hole wall 11112 . One end of the third hole wall 11113 is connected to an end of the second hole wall 11112 away from the first hole wall 11111 , and the other end of the third hole wall 11113 is connected to the first end face 11 .
[0071] Among them, see Figure 3 The peripheral wall 31 of the lens 3 may be formed with an overlapping portion 312 , and the overlapping portion 312 overlaps the second hole wall 11112 and fits with the second hole wall 11112 and the third hole wall 11113 .
[0072] The overlapped portion 312 of the lens 3 is in contact with the second hole wall 11112 and the third hole wall 11113, and the second hole wall 11112 is parallel to the first end face 11, and the second hole wall 11112 and the third hole wall 11113 of the lens barrel 1 provide a stable support and bearing place for the overlapped portion 312 of the lens 3. The risk of the lens 3 shaking inside the vehicle-mounted lens 100 is reduced, the stability of the lens 3 inside the vehicle-mounted lens 100 is improved, and the clarity and stability of the imaging of the vehicle-mounted lens 100 are enhanced.
[0073] In some embodiments, see Figure 3 The second hole wall 11112 and the third hole wall 11113 can also be perpendicular to each other.
[0074] By arranging the second hole wall 11112 and the third hole wall 11113 vertically, foreign matter and liquid are less likely to slide into the third hole wall 11113 along the second hole wall 11112, thereby improving the sealing of the internal structure of the vehicle lens 100 and increasing the service life and stability of the vehicle lens 100.
[0075] Of course, in other embodiments, the second hole wall 11112 and the third hole wall 11113 may not be arranged vertically. Exemplarily, the angle between the second hole wall 11112 and the third hole wall 11113 may be an acute angle. In some embodiments, the second hole wall 11112 may also be provided with an avoidance groove 111121, which is arranged around the periphery of the first hole wall 11111.
[0076] like Figure 2 As shown, the vehicle-mounted lens 100 may further include a waterproof ring 5, which is annular and is disposed in the avoidance groove 111121 ( Figure 3 ) and abuts against the overlapping portion 312. The avoidance groove 111121 is used to accommodate the waterproof ring 5.
[0077] From the above, we can see that Figure 2 and Figure 3 The waterproof ring 5 is located on the periphery of the first peripheral wall 311 of the lens 3. The waterproof ring 5 can reduce the damage of moisture and dust to the lens 3 and the heating element 2, improve the sealing of the internal structure of the vehicle lens 100, and increase the service life and stability of the vehicle lens 100.
[0078] It should be noted that the present application does not limit the material of the waterproof ring 5, and the material can be selected according to the actual situation. For example, the material of the waterproof ring 5 can be silicone.
[0079] Since silicone has good elasticity and strong deformation recovery ability, the silicone waterproof ring 5 can maintain good sealing performance even when the heating element 2 heats the surrounding environment. At the same time, silicone has excellent anti-aging, weather resistance and chemical stability, which can reduce the risk of moisture and pollutants entering the interior of the lens and extend the service life of the vehicle-mounted lens 100.
[0080] In some embodiments, see Figure 3 The hole wall 1111 of the mounting hole 111 may further include a fourth hole wall 11114. The fourth hole wall 11114 is annular and is located inside the first hole wall 11111, and one end is connected to an end of the first hole wall 11111 away from the first end face 11. The fourth hole wall 11114 is parallel to the first end face 11, and a portion of the peripheral wall 31 of the lens 3 is in contact with the fourth hole wall 11114.
[0081] A portion of the peripheral wall 31 of the lens 3 is in contact with the fourth hole wall 11114, and the fourth hole wall 11114 is parallel to the first end face 11, which can fasten the lens 3 and fix the lens 3 in a designed position, further reducing the risk of the lens 3 shaking inside the vehicle-mounted lens 100, further improving the stability of the lens 3 in the vehicle-mounted lens 100, and enhancing the clarity and stability of the imaging of the vehicle-mounted lens 100.
[0082] In some embodiments, see Figure 2 The vehicle-mounted lens 100 may further include a pressing ring 6. The pressing ring 6 is sleeved on the periphery of the lens barrel 1, and is partially located on the side where the first end surface 11 is located, and is arranged opposite to the mounting hole 111. Among them, at least a part of the pressing ring 6 abuts against the lens 3.
[0083] The pressing ring 6 is sleeved on the outer periphery of the lens barrel 1 and is arranged opposite to the mounting hole 111. The pressing ring 6 abuts against the lens 3 to further tighten the lens 3, so that the lens 3 is fixed in a designed position, which can reduce the risk of displacement of the lens 3 due to vibrations generated during transportation and operation, extend and improve the stability of the lens 3 in the vehicle-mounted lens 100, and enhance the clarity and stability of the imaging of the vehicle-mounted lens 100.
[0084] It should be noted that the present application does not limit the material of the pressure ring 6, and the material can be selected according to actual conditions.
[0085] Exemplarily, the material of the pressing ring 6 can be metal, such as aluminum. Since aluminum has a low density, using aluminum to make the pressing ring 6 can significantly reduce the weight of the pressing ring 6, which is beneficial to the lightweight of the overall structure of the vehicle-mounted lens 100. On the other hand, aluminum is easy to cut, stamp and form, so the cost of making the pressing ring 6 can be reduced and the efficiency of producing the pressing ring 6 can be improved.
[0086] For example, the material of the pressing ring 6 can be silicone. Since silicone has good elasticity, wear resistance and temperature resistance, the pressing ring 6 can fit the vehicle lens 100 tightly, reduce dust and dirt from entering the vehicle lens 100, and extend the service life of the vehicle lens 100.
[0087] Exemplarily, the material of the pressing ring 6 may also be polycarbonate. Polycarbonate is a tough plastic material widely used in various optical product pressing rings 6. It can provide sufficient hardness to resist external impact and extend the service life of the vehicle-mounted lens 100.
[0088] For example, the material of the pressing ring 6 can also be thermoplastic polyurethane (TPU). Since TPU has both softness and strength, and has the advantages of wear resistance, tear resistance, oil resistance, and hydrolysis resistance, the pressing ring 6 can provide good protection for the vehicle lens 100, and provide a certain buffer after a collision, thereby extending the service life of the vehicle lens 100.
[0089] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0090] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
