Description

Technical Field

[0001] This application relates to the technical field of unmanned aerial vehicles, and particularly to a lens assembly and an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle usually includes a lens assembly, which is used for shooting or for detecting obstacles on the flight path of the unmanned aerial vehicle. During the operation of the lens assembly, a high requirement is placed on the parallelism of the two lens axes. When the two lens axes are not parallel, the shooting effect of the lens assembly is affected. Generally, the lens assembly is installed on a cross beam. In order to improve the parallelism of the two lenses, the lens assembly has a high requirement for the installation accuracy. However, after the cross beam undergoes high and low temperature changes or the unmanned aerial vehicle is used under long-term vibration conditions, the existing cross beam cannot meet the parallelism of the two lens axes, resulting in the degradation of the parallax map of the lens assembly and seriously affecting the normal use of the lens assembly. Summary of the Invention

[0018] In a possible design, the first cross beam and the second cross beam enclose a cavity structure.

[0019] Through the cooperation of the thermostat and the sensor, the lens assembly in this application can achieve online adjustment and continuous adjustment of the included angle between the two lens axes during use, and can solve the problem of difficult adjustment after the lens assembly is installed in the prior art.

[0063] The embodiments of the present application provide a lens assembly that can be used in the field of drones or the field of driverless or other fields that require taking pictures or videos. As Figure 1 shown, the lens assembly includes a cross beam 1, a first lens 2 and a second lens 3 that are mounted on the cross beam 1 and distributed along the first direction X. Among them, the cross beam 1 includes a first cross beam 11 and a second cross beam 12. The first cross beam 11 has a first end 111 and a second end 112 along the first direction X, and the second cross beam 12 has a third end 121 and a fourth end 122 along the first direction X. The first end 111 is connected to the third end 121 and is both connected to the first lens 2. The second end 112 is connected to the fourth end 122 and is both connected to the second lens 3. The lens assembly further includes a thermostat 4 and a sensor 5. The thermostat 4 is connected to the first cross beam 11, and the sensor 5 is connected to the second cross beam 12. The sensor 5 is used to detect the deformation parameters of the second cross beam 12. The thermostat 4 can heat or cool the first cross beam 11 according to the deformation parameters detected by the sensor 5, so that the first cross beam 11 expands or contracts, and the first cross beam 11 can drive the second cross beam 12 to deform during the expansion or contraction process.

[0064] In this embodiment, the first lens 2 and the second lens 3 are distributed along the first direction X and mounted on the cross beam 1. After installation, the axes of the first lens 2 and the second lens 3 are parallel to each other (i.e., the included angle between the axes of the two lenses is 0°), so as to ensure the shooting effect of the lens assembly.

[0065] Meanwhile, the crossbeam 1 includes a first crossbeam 11 and a second crossbeam 12. When the lens assembly works for a long time, the crossbeam 1 bends due to reasons such as environmental temperature changes, resulting in an angle (non-parallel) between the axes of the two lenses. Since the deformation parameter of the second crossbeam 12 has a one-to-one correspondence with the angle between the axes of the two lenses, the deformation parameter of the second crossbeam 12 can be detected by the sensor 5 provided on the second crossbeam 12. According to the deformation parameter of the second crossbeam 12 (the angle between the two lenses) detected by the sensor 5, it can be determined whether to heat or cool the first crossbeam 11, and the temperature for heating or cooling the first crossbeam 11 can be determined. Thus, the temperature controller 4 provided on the first crossbeam 11 can heat or cool the first crossbeam 11 to a preset temperature, causing the first crossbeam 11 to undergo thermal deformation (expansion or contraction). When this thermal deformation is transmitted to the second crossbeam 12, it can drive the second crossbeam 12 to bend, thereby adjusting the overall bending of the crossbeam 1 and making the axes of the two lenses parallel again, ensuring the shooting effect of the lens assembly. Therefore, the lens assembly in this embodiment can, through the cooperation of the temperature controller 4 and the sensor 5, achieve on-line adjustment and continuous adjustment of the angle between the axes of the two lenses during use, and can solve the problem of difficult adjustment of the existing technology after the lens assembly is installed.

[0066] Among them, the first crossbeam 11 and the second crossbeam 12 can be of an integral structure, and the first crossbeam 11 and the second crossbeam 12 are of the same material structure, so that the deformation of the first crossbeam 11 can be transmitted to the second crossbeam 12. The temperature controller 4 is a thermoelectric temperature controller. One side of the temperature controller 4 is the hot end, and the other side is the cold end. When the current reverses, the original hot end will become the cold end, and the original cold end will become the hot end. Therefore, the effect of heating or cooling the first crossbeam 11 by the temperature controller 4 can be controlled by changing the direction of the current.

[0067] Take Figure 1 the shown lens assembly as an example. When the environmental temperature is 20°C, the temperature controller 4 heats the first crossbeam 11 with a thermal power of 10W for 600 seconds. At this time, the displacement at the maximum displacement of the first lens 2 and the second lens 3 is 0.14mm, and the corresponding angle between the axes of the two lenses is 0.086°. This angle range can cover the angle regulation range required during the normal operation of the lens assembly and meet the adjustment requirements of the angle between the axes of the two lenses during use.

[0068] In a specific embodiment, the lens assembly further includes a heat sink (not shown in the figure). One end of the temperature controller 4 is connected to the first crossbeam 11, and the other end is connected to the heat sink. When the temperature controller 4 heats the first crossbeam 11, the end of the temperature controller 4 connected to the heat sink is the cold end. When the temperature controller 4 cools the first crossbeam 11, the end of the temperature controller 4 connected to the heat sink is the hot end.

[0069] In this embodiment, when the temperature controller 4 heats the first crossbeam 11, the cold end of the temperature controller 4 connected to the heat sink has a relatively low temperature and needs to absorb heat. The heat sink can absorb the heat in the air, improving the heat absorption efficiency of the cold end of the temperature controller 4, thereby enhancing the heating efficiency of the hot end of the temperature controller 4 for the first crossbeam 11. When the temperature controller 4 cools the first crossbeam 11, the hot end of the temperature controller 4 connected to the heat sink has a relatively high temperature. The heat sink can reduce the thermal resistance between the hot end and the air, enabling the hot end to dissipate heat better, thereby improving the heat dissipation efficiency of the hot end of the temperature controller 4 and further enhancing the heat dissipation efficiency of the cold end of the temperature controller 4 for the first crossbeam 11.

[0070] In a specific embodiment, during the expansion or contraction of the first crossbeam 11, it can drive the second crossbeam 12 to bend. The sensor 5 is used to detect the stress of the second crossbeam 12, or the sensor 5 is used to detect the bending angle of the second crossbeam 12. That is, the deformation parameter of the second crossbeam 12 mentioned above can be the stress or bending angle of the second crossbeam 12.

[0071] In this embodiment, when the crossbeam 1 of the lens assembly bends, resulting in an included angle between the axes of the two lenses, since there is a one-to-one correspondence between the bending stress of the second crossbeam 12 and the included angle between the axes of the two lenses, this bending stress can reflect the degree of the included angle between the axes of the two lenses. Or, there is a one-to-one correspondence between the bending angle of the second crossbeam 12 and the included angle between the axes of the two lenses. Therefore, this bending angle can reflect the degree of the included angle between the axes of the two lenses. Thus, it is possible to determine whether the temperature controller 4 needs to heat or cool the first crossbeam 11 based on the above-mentioned bending stress or bending angle, and to determine the degree of heating or cooling. Furthermore, the first crossbeam 11 undergoes expansion or contraction deformation due to the heating or cooling by the temperature controller 4. When the first crossbeam 11 expands or contracts, it can drive the second crossbeam 12 to bend and deform, thereby eliminating the overall bending of the crossbeam 1 and making the included angle between the axes of the two lenses return to 0° again, achieving continuous and on-line detection and control of the included angle between the lens axes.

[0072] Among them, the sensor 5 can also be used to detect other parameters on the second crossbeam 12 that can reflect the bending degree of the second crossbeam 12, and this parameter has a one-to-one correspondence with the included angle between the axes of the two lenses, enabling on-line calibration of the included angle between the axes of the two lenses.

[0073] In another specific embodiment, as Figure 5 shown, the first crossbeam 11 is provided with a first recess 113 and a second recess 114 that penetrate the first crossbeam 11 along the third direction Z.

[0074] In this embodiment, the first recess 113 and the second recess 114 are located on the first cross beam 11, which can reduce the area of this part of the first cross beam 11 and reduce the risk of heat generated by the thermostat 4 being transferred to the second cross beam 12. Thus, the risk of thermal deformation of the second cross beam 12 is reduced, which helps to ensure that the second cross beam 12 can only be bent and deformed under the drive of the first cross beam 11. As a result, the deformation parameters of the second cross beam 12 detected by the sensor 5 are only the parameters of the bending deformation of the second cross beam 12 following the first cross beam 11, improving the accuracy of on-line detection and control. Furthermore, the bending angle of the control rear cross beam 1 is made close to 0°.

[0075] Among them, the forms of the first recess 113 and the second recess 114 are not limited, as long as they can reduce the heat transfer between the first cross beam 11 and other parts of the lens assembly. For example, Figure 5 in the illustrated embodiment, the first recess 113 and the second recess 114 are two groove structures of the same size and are distributed along the same center line in the second direction Y. Or, as Figure 6 shown, the first recess 113 and the second recess 114 are both through-hole structures and are located in the middle of the first cross beam 11 along the second direction Y.

[0076] Specifically, as Figure 5 and Figure 6 shown, the first recess 113 is located at a position on the first cross beam 11 close to the first end 111, and there is a first distance a between the first recess 113 and the first end 111. The second recess 114 is located at a position on the first cross beam 11 close to the second end 112, and there is a second distance b between the second recess 114 and the second end 112. 0.5 mm ≤ a ≤ 2 mm, 0.5 mm ≤ b ≤ 2 mm. Among them, the above-mentioned first distance a can specifically be 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, etc., and the above-mentioned second distance b can specifically be 0.5 mm, 0.7 mm, 1.1 mm, 1.5 mm, 2 mm, etc.

[0077] In this embodiment, the ranges of the first distance a and the second distance b are 0.5 mm ≤ a ≤ 2 mm and 0.5 mm ≤ b ≤ 2 mm respectively, which can prevent the heat generated by the thermostat 4 from being easily transferred from the first cross beam 11 to the second cross beam 12, and at the same time ensure that the first end 111 and the second end 112 of the first cross beam 11 can be normally deformed when heated or cooled. Thus, the first cross beam 11 can normally drive the second cross beam 12 to deform, improving the sensitivity and accuracy of controlling the bending angle of the cross beam 1.

[0078] Among them, the first distance a and the second distance b can be equal or unequal. In this embodiment, the first distance a and the second distance b are equal.

[0079] More specifically, asFigure 5 and Figure 6 As shown in Figure 6 , along the second direction Y, the dimension of the first recess 113 is h1, the dimension of the second recess 114 is h2, and the dimension of the first cross beam 11 is H, where 0.3 ≤ h1 / H ≤ 0.8 and 0.3 ≤ h2 / H ≤ 0.8. For example, h1 / H can specifically be: 0.3, 0.5, 0.6, 0.8, etc., and h2 / H can specifically be: 0.3, 0.5, 0.6, 0.8, etc.

[0080] In this embodiment, after the first cross beam 11 is provided with the first recess 113 and the second recess 114, the dimension of the first cross beam 11 along the second direction Y at the location where the first recess 113 is provided is H - h1, and the dimension of the first cross beam along the second direction Y at the location where the second recess 114 is provided is H - h2. Therefore, the first recess 113 and the second recess 114 can reduce the area of the first cross beam 11, thereby reducing the heat transferred from the first cross beam 11 to the second cross beam 12.

[0081] When h1 / H and h2 / H are too large (for example, h1 / H > 0.8, h2 / H > 0.8), the dimensions H - h1 and H - h2 of the first cross beam 11 along the second direction Y at the first recess 113 and the second recess 114 are too small, thereby reducing the strength and stiffness of the first cross beam 11 at the first recess 113 and the second recess 114, and causing the first cross beam 11 to be prone to fracture when expanding or contracting. When h1 / H and h2 / H are too small (for example, h1 / H < 0.3, h2 / H < 0.3), the dimensions H - h1 and H - h2 of the first cross beam 11 along the second direction Y at the first recess 113 and the second recess 114 are too large, resulting in the first recess 113 and the second recess 114 being unable to effectively reduce the heat transferred from the first cross beam 11 to the second cross beam 12. As a result, in addition to bending deformation under the drive of the first cross beam 11, the second cross beam 12 may also undergo thermal deformation, reducing the accuracy of on-line detection and control of the bending angle of the cross beam 1. In this embodiment, when 0.3 ≤ h1 / H ≤ 0.8 and 0.3 ≤ h2 / H ≤ 0.8, the heat transferred from the first cross beam 11 to the second cross beam 12 can be reduced, thereby improving the accuracy of on-line detection and control of the bending angle of the cross beam 1 and ensuring the strength and stiffness of the first cross beam 11, such that the structure is not prone to fracture when the first cross beam 11 is deformed.

[0082] Among them, the dimension h1 and the dimension h2 can be equal or unequal. In this embodiment, the dimension h1 and the dimension h2 are equal.

[0083] In the above embodiments, as Figure 2 shown, along the first direction X, the thermostat 4 is located in the middle of the first cross beam 11, and / or the sensor 5 is located in the middle of the second cross beam 12.

[0084] In this embodiment, the thermostat 4 is located at the middle of the first crossbeam 11 along the first direction X, such that the distances from the thermostat 4 to the first end 111 and to the second end 112 are equal. This allows the heat generated by the thermostat 4 to be evenly conducted to all parts of the first crossbeam 11, enabling each part of the first crossbeam 11 along the first direction X to deform uniformly. As a result, the second crossbeam 12 can deform stably under the drive of the first crossbeam 11. Meanwhile, when the distances from the thermostat 4 to the first end 111 and to the second end 112 are equal, it can also prevent the risk that the heat generated by the thermostat 4 is transferred to the second crossbeam 12 through the first end 111 or the second end 112 when the thermostat 4 is close to the first end 111 or the second end 112, further improving the accuracy of online detection and control of the bending angle of the crossbeam 1.

[0085] When the second crossbeam 12 bends and deforms under the drive of the first crossbeam 11, the deformation parameters of the middle part of the second crossbeam 12 along the first direction X can represent the deformation parameters of the second crossbeam 12. At this time, when the sensor 5 is located at the middle of the second crossbeam 12 (the distances from the sensor 5 to the third end 121 and to the fourth end 122 are equal), it can improve the accuracy of the sensor 5 in detecting the deformation parameters of the second crossbeam 12, further improving the accuracy of online detection and control of the bending angle of the crossbeam 1.

[0086] Meanwhile, as Figure 1 shown, the back surface of the thermostat 4 is connected to the outer wall of the first crossbeam 11 for conducting heat to the first crossbeam 11 to achieve heating or cooling of the first crossbeam 11. The control panel of the thermostat 4 faces outward for easy operation; the sensing surface of the sensor 5 is connected to the outer wall of the second crossbeam 12 for detecting the stress or bending angle of the second crossbeam 12.

[0087] In each of the above embodiments, as Figure 4 shown, the first crossbeam 11 and the second crossbeam 12 are arc-shaped.

[0088] In this embodiment, the first crossbeam 11 is controlled by the thermostat 4, expands due to heat or contracts due to cooling to generate deformation, and at the same time drives the second crossbeam 12 to also deform. Since the heat transfer effect of the arc-shaped structure is better, the temperature distribution is more uniform, and the deformation effect of heat expansion or cooling contraction is more obvious, the first crossbeam 11 and the second crossbeam 12 can be selected as arc-shaped structures.

[0089] In other embodiments, the first crossbeam 11 and the second crossbeam 12 can also be of a flat structure or other shaped structures. The present application does not limit the shapes of the first crossbeam 11 and the second crossbeam 12.

[0090] Specifically, as Figure 4 shown, the first crossbeam 11 has a planar portion 115, and the thermostat 4 is installed on the planar portion 115.

[0091] In this embodiment, since the first cross beam 11 is an arc-shaped structure and the thermostat 4 has relatively high requirements for the flatness of the installation position, a flat portion 115 is provided in the middle of the first cross beam 11 for installing the thermostat 4, so that the thermostat 4 is closely attached to the first cross beam 11, conducting the heat of the thermostat 4 to the first cross beam 11 and ensuring the heat conduction efficiency.

[0092] Wherein, a heat-conducting medium or a heat-conducting pad can also be covered between the contact surfaces of the first cross beam 11 and the thermostat 4, so that the heat can be better conducted from the thermostat 4 to the first cross beam 11, and the heat conduction efficiency can be further improved.

[0093] At the same time, as Figure 4 shown, the second cross beam 12 has a main body portion 123 and a mounting portion 124, and the mounting portion 124 is used for mounting the sensor 5. Among them, the thickness of the mounting portion 124 is smaller than the thickness of the main body portion 123.

[0094] In this embodiment, since the sensor 5 has requirements for the structure of the installation position, the second cross beam 12 is provided with a main body portion 123 and a mounting portion 124. Among them, the mounting portion 124 is located in the middle of the second cross beam 12 and is used for mounting the sensor 5 to ensure the normal operation of the sensor 5. At the same time, when the thickness of the mounting portion 124 is smaller than the thickness of the main body portion 123, the thinner mounting portion 124 is more likely to deform. When the second cross beam 12 is deformed driven by the first cross beam 11, it is convenient for the sensor 5 to detect the deformation parameters of the second cross beam 12.

[0095] In the above embodiments, as Figure 1 shown, the first cross beam 11 and the second cross beam 12 enclose a cavity structure.

[0096] In this embodiment, the first cross beam 11 and the second cross beam 12 are connected at the ends and enclose a cavity structure in the middle, reducing the overall weight of the lens assembly, thereby being able to reduce the overall weight of the drone and lower the energy consumption of the drone.

[0097] Among them, when both the first cross beam 11 and the second cross beam 12 are arc-shaped structures, they can enclose a cavity structure similar to an ellipse.

[0098] In addition, as Figure 2As shown in the figure, the lens assemblies in the above embodiments may further include components such as a bracket 6, a first FPC connector 7, a second FPC connector 8, a first photosensitive element backplane 9, and a second photosensitive element backplane 10. Among them, the bracket 6 is located below the first cross beam 11 and is used to support the entire lens assembly. The first FPC connector 7 and the second FPC connector 8 are respectively located below the first lens 2 and the second lens 3 and are used to connect circuits, transmit and receive signals, so as to control the working states of the first lens 2 and the second lens 3. The first photosensitive element backplane 9 and the second photosensitive element backplane 10 are respectively located on the backs of the first lens 2 and the second lens 3 and are used to enhance the structural strength of the lens part and at the same time enhance the heat dissipation performance of the internal photosensitive element.

[0099] In addition, the present application also provides a drone, which includes a housing and a lens assembly installed in the housing. Among them, the lens assembly is the lens assembly described in any of the above embodiments.

[0100] In this embodiment, the housing is used to place the lens assembly and other drone components, and the lens assembly is used for the shooting and imaging of the drone.

[0101] In a specific embodiment, the drone may further include a control component, which is used to control the heating or cooling of the temperature controller 4 according to the deformation parameters detected by the sensor 5.
