Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mounting support, in particular to an adjusting support, a multi-lens holder and a flight shooting device. BACKGROUND

[0002] In recent years, people are more and more like to use unmanned aerial vehicles to mount cameras for shooting, and the technical level is constantly improving. For example, the gimbal is used to improve the anti-shake ability, and multiple lenses are integrated to realize multiple functions. Currently, there is even a four-light gimbal, which integrates a zoom lens, a laser ranging module, a fixed focus lens and a thermal imaging lens.

[0003] The unmanned aerial vehicle can be provided with a zoom lens and a laser ranging module at the same time, and the zoom lens and the laser ranging module can be used for accurate ranging, but the light paths of the two devices are required to be in a highly parallel state in terms of structure.

[0004] A common method is to test and level, and then completely fix the laser ranging module and the zoom lens by dispensing glue to form a lens assembly fixed together. The laser ranging module and the zoom lens included in the lens assembly are not detachable. The dispensing method is simple in process, and the lens assembly has excellent stability and shock resistance. However, the overall dispensing method also makes it extremely difficult to repair, and even a small damage will cause the entire lens assembly to be replaced, which is not conducive to cost control and recycling.

[0005] Another method is to use a control system to control a motor for leveling, but the motor is large in size and heavy in weight, which is not suitable for the lightweight demand in the unmanned aerial vehicle mounting field. CONTENT OF THE INVENTION

The adjusting member is rotatably connected to the first connecting frame by the first screw, and the second connecting frame is rotatably connected to the adjusting member by the second screw. The second screw intersects with the first screw. The first connecting frame is used for connecting the first shooting device, and the second connecting frame is used for connecting the second shooting device.

In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0043] Reference Figure 1 , Figure 1 A multi-lens holder in the present application is shown. The multi-lens holder 1100 can include a first shooting device 200 and a second shooting device 300. The multi-lens holder 1100 can include a plurality of shooting devices which can be fixed respectively and then combined together. The multi-lens holder 1100 can be arranged at an external mounting position, and can also include a mounting seat or a mounting shell. In an exemplary embodiment, the multi-lens holder 1100 further includes an adjusting support 100 for connecting the first shooting device 200 to the second shooting device 300.

[0044] Optionally, the first shooting device 200 is a zoom lens, and the second shooting device 300 is a laser ranging module, and the two shooting devices can perform accurate ranging. The first shooting device 200 can have a first optical axis L1, and the light entrance side of the first shooting device 200 along the first optical axis L1 can be referred to as the front side or the object side, and the first shooting device 200 includes a first object side end 210. The second shooting device 300 can have a second optical axis L2, and the light entrance side of the second shooting device 300 along the second optical axis L2 can also be referred to as the front side or the object side, and the second shooting device 300 includes a second object side end 310. The adjusting support 100 is used to adjust the first optical axis L1 and the second optical axis L2 to be parallel.

[0045] The present application provides an adjusting support 100, which can include a first connecting frame 110, a first screw 1, an adjusting piece 130, a second screw 2, a second connecting frame 120, and a positioning screw 3. Reference Figures 2 to 4 In an exemplary embodiment, the adjusting support 100 further includes an elastic piece 4.

[0046] Reference Figure 1For convenience of description, a space orthogonal coordinate system XYZ is established. The adjusting member 130 is rotatably connected to the first connecting frame 110 by a first screw 1, which can be substantially parallel to the Z-axis direction, and thus can change the position of the adjusting member 130 relative to the first connecting frame 110 along the XY plane. The second connecting frame 120 is rotatably connected to the adjusting member 130 by a second screw 2. When the adjusting member 130 rotates relative to the first connecting frame 110, the second connecting frame 120 also rotates relative to the first connecting frame 110 about the first screw 1, and thus the position of the second screw 2 in space changes, Figure 1 and Figure 4 The position shown in FIG. 2 is an optional position, and thus the state of the adjusting support 100 can be adjusted.

[0047] The second screw 2 intersects the first screw 1. Exemplarily, the second screw 2 can be parallel to the XY plane, and thus the second screw 2 is perpendicular to the first screw 1 in space. Figure 1 In the position shown in FIG. 2, the second screw 2 can be parallel to the Y-axis direction. After adjustment, the second screw 2 can form a certain angle with the Y-axis direction and with the X-axis direction.

[0048] The second connecting frame 120 can also rotate about the second screw 2, and the rotation plane can be parallel to the Z-axis direction. Since the second screw 2 intersects the first screw 1, the second connecting frame 120 realizes attitude adjustment in two planes relative to the first connecting frame 110, and the two rotation planes intersect, so that the second connecting frame 120 realizes full-direction adjustment in a certain range. After adjustment, the first screw 1 and the second screw 2 can be tightened, which helps to lock the state of the adjusting support 100.

[0049] The first connecting frame 110 is used to connect the first photographing device 200. The specific mounting and fixing attitude can be designed according to actual structure, size, etc. Exemplarily, the first photographing device 200 is arranged in an attitude in which the first optical axis L1 is parallel to the X-axis direction. The second connecting frame 120 is used to connect the second photographing device 300, and the second photographing device 300 needs to be adjusted to an attitude in which the second optical axis L2 is parallel to the X-axis direction.

[0050] Reference is made to Figure 2 and Figure 5The second connecting frame 120 is provided with a waist hole 1201 around the second screw 2. The second connecting frame 120 can be provided with a shaft hole for passing the second screw 2. The waist hole 1201 can be an arc-shaped waist hole around the shaft hole. The positioning screw 3 passes through the waist hole 1201 and is threadedly connected to the first connecting frame 110. The nut of the positioning screw 3 can be referred to as a third nut 31, which overlaps the second connecting frame 120. When the positioning screw 3 is not installed, the rotation angle of the second connecting frame 120 and the adjusting member 130 around the first screw 1 can reach 90° or more. However, due to the length of the positioning screw 3, the rotation angle can be limited to be smaller, for example, less than or equal to 20°, which can ensure that the adjusting range is sufficient for use. The curvature of the waist hole 1201 can ensure the rotation of the second connecting frame 120 around the second screw 2.

[0051] Exemplarily, the width of the waist hole 1201 is greater than the diameter of the threaded segment of the positioning screw 3 and the third threaded segment 32, and the width of the waist hole 1201 is sufficient to absorb the positional deviation caused by the movement of the second connecting frame 120. In this way, a usable adjusting range can be achieved based on a simple structure, and the adjusting effect can be ensured. The first connecting frame 110 can be provided with a threaded hole for matching the positioning screw 3. In other embodiments, the threaded hole is provided at a radial position of the rotating shaft.

[0052] The elastic member 4 is used to drive the second connecting frame 120 to abut against the nut of the positioning screw 3. The elastic member 4 cooperates with the positioning screw 3 to limit the position of the second connecting frame 120 around the first screw 1 and can be controlled to finely adjust. By arranging the adjusting member 130, the mutual posture of the first connecting frame 110 and the second connecting frame 120 can be adjusted, and the first optical axis L1 of the first photographing device 200 and the second optical axis L2 of the second photographing device 300 can be adjusted to be parallel. The first screw 1 and the second screw 2 can lock the adjusted position. The adjusting bracket 100 is easy to install and can realize full-angle adjustment within a certain range to meet the light path leveling requirement. The connection mode of the first photographing device 200 and the second photographing device 300 enables at least one of the two to be disassembled without completely destroying the disassembly, and at least the first connecting frame 110 and the second connecting frame 120 in the adjusting bracket 100 can be repeatedly used, and the first screw 1 and the second screw 2 can be prevented from loosening or locked. The maintenance cost of the adjusting bracket 100 is low. At least the screw and the elastic member 4 can be made into standard parts, which is convenient for batch installation and use.

[0053] Reference Figure 1 and Figure 3 The first connecting frame 110, the second connecting frame 120, and the adjusting member 130 are structurally delicate and light in weight, which can be suitable for unmanned aerial vehicle mounting field. The first connecting frame 110 can lift the adjusting member 130 and can maintain good rigidity and stability through screw locking.

[0054] The first connecting frame 110 is used to be detachably connected to the first shooting device 200, for example, by screwing. The second connecting frame 120 is used to be detachably connected to the second shooting device 300, for example, also by screwing. The adjusting support 100 is easy to maintain, and the single shooting device can be detached for maintenance and replacement.

[0055] The first connecting frame 110, the positioning screw 3 and the second connecting frame 120 can be glued and fixed. For example, the third nut 31 of the positioning screw 3 can be glued, and the screw hole of the first connecting frame 110 can be glued. The adjusting support 100 can firmly and reliably maintain the overall attitude after leveling, and is also beneficial to prevent loosening caused by long-term vibration. The first screw 1 and the second screw 2 can be glued differently, and the adjusting support 100 can be less glued and more environmentally friendly. While the two ends of the positioning screw 3 are glued, the first connecting frame 110 and the second connecting frame 120 can not be directly glued and fixed, which avoids high rigidity and is beneficial to use in a vibration environment such as a UAV mounting. During ground testing, the adjusting support 100 can also be used without gluing.

[0056] Exemplarily, the elastic member 4 is a spring sleeved on the positioning screw 3 and clamped between the first connecting frame 110 and the second connecting frame 120. The two ends of the spring can also be glued and fixed. In order to be applicable in a vibration environment and reduce rigidity, the middle part of the spring is not glued and fixed.

[0057] The elastic member 4 can be arranged at other positions and configured as a tension spring or a torsion spring. The compression spring has a small size, and the structure is simple and convenient to install by sleeving on the positioning screw 3. The nut screwed on the screw rod can also be regarded as a nut. The integrated screw is simpler and more applicable.

[0058] Reference Figure 2 and Figure 5 The first screw 1 includes a first threaded section 12 threadedly connected to the first connecting frame 110 and a first shaft section 13 rotationally connected to the adjusting member 130. The second screw 2 includes a second threaded section 22 threadedly connected to the adjusting member 130 and a second shaft section 23 rotationally connected to the second connecting frame 120. The first shaft section 13 and the second shaft section 23 can respectively realize relatively precise rotational connection. The first screw 1 and the second screw 2 can be made into an integrated standard part, which is convenient to use.

[0059] Reference Figure 2 and Figure 5The adjusting support 100 can include a plurality of elastic washers (or referred to as a washer), specifically, nylon washers 5. The first connecting frame 110 and the adjusting member 130, the adjusting member 130 and the nut of the first screw 1, i.e., the first nut 11, the adjusting member 130 and the second connecting frame 120, and the second connecting frame 120 and the nut of the second screw 2, i.e., the second nut 21, are respectively provided with a nylon washer 5. The nylon washer 5 is sleeved on the corresponding screw. The elastic washer has a certain elasticity and can be used to absorb vibration, especially low-frequency vibration. The nylon washer 5 has good lubricating effect, which is beneficial to the leveling operation; the strength of the nylon washer 5 is also appropriate, which can keep the posture of the adjusting member 130 and the second connecting frame 120 adjusted.

[0060] Exemplarily, the first connecting frame 110 includes a first connecting table 111 for connecting the first screw 1. Referring to Figure 1 and Figure 2 , according to the design position, after the first connecting frame 110 is fixed with the first shooting device 200, the first connecting table 111 is located at the periphery of the first shooting device 200, for example, at one side along the Y-axis direction. Along the first optical axis L1, the first connecting table 111 is close to the first object side end 210 and away from the rear end relative to the first shooting device 200, specifically, can be at the rear side of the first object side end 210. It can avoid affecting the field of view of the first shooting device 200, and ensure that the second shooting device 300 can be adjusted. The first screw 1 is perpendicular to and deviates from the first optical axis L1, and the second screw 2 is perpendicular to the first screw 1. The space of the adjusting support 100 in use is relatively compact relative to the first shooting device 200, and the actual space position of the second shooting device 300 is better.

[0061] Referring to Figure 6 , the multi-lens holder 1100 can include at least one glass window 400. Each shooting device can correspond to one glass window 400, and the camera device is often arranged behind the glass window 400. The glass window 400 can transmit light and protect the camera device. The second shooting device 300 has a certain field of view angle, and the second shooting device 300 is designed to be closer to the front and closer to the glass window 400, which is beneficial to making the size of the glass window 400 as small as possible under the premise that the frame of the glass window 400 or the non-transparent shell of the multi-lens holder 1100 does not block the field of view angle, reducing the cost and assembly difficulty of the glass window 400. The glass window 400 also has the problem of reflection, and the second shooting device 300 is close to the glass window 400, which can reduce the influence of reflection on performance. In addition, since the actual position of the second shooting device 300 is adjusted, a certain gap is left in front of the second shooting device 300 as a margin, which ensures that the adjusting space is sufficient, avoids the collision and interference between the second shooting device 300 and the glass window 400, and makes the glass window 400 top off or the posture of the second shooting device 300 deformed.

[0062] The first connecting frame 110 can further include a first connecting plate 112. The first connecting plate 112 is used to connect the first shooting device 200 and to connect the positioning screw 3. The first connecting table 111 is connected to the edge of the first connecting plate 112, and the two are exemplarily integrated. The first connecting table 111 and the first connecting plate 112 are arranged in a substantially thin plate structure, and the first connecting frame 110 and the entire adjusting support 100 are relatively thin. The first connecting frame 110 is a die-cast metal frame, which is easy to manufacture and convenient for secondary recycling of metal materials. In order to ensure strength and reduce weight, the first connecting plate 112 can be provided with a hollow hole, and a reinforcing rib can be arranged.

[0063] During adjustment, before the screw is tightened, the adjusting part 130 can be above the first connecting table 111, and the second connecting frame 120 can be transversely arranged with the adjusting part 130.

[0064] Reference Figure 2 , Figure 3 and Figure 5 The adjusting part 130 includes a second connecting table 131 for connecting the first screw 1 and a third connecting table 132 for connecting the second screw 2. Although the posture of the adjusting part 130 is adjusted, in general, along the first optical axis L1, the second connecting table 131 is located on the object side, i.e., the front side, of the third connecting table 132. The distance between the first screw 1 and the second screw 2 can be set to be less than the distance between the second screw 2 and the positioning screw 3. The adjusting support 100, especially the adjusting part 130, is compact in structure; in the case of ensuring the adjustment range of the second shooting device 300, the space occupied is reduced; the relatively far positioning screw 3 is conducive to fine adjustment and reduces the action amplitude. The first screw 1, the second screw 2, and the positioning screw 3 can be arranged in a row.

[0065] Exemplarily, the second connecting frame 120 includes a second connecting plate 121 and a third connecting plate 122. The second connecting plate 121 is provided with a waist hole 1201 and is used to connect the adjusting part 130, and the third connecting plate 122 is deflected relative to the second connecting plate 121. The third connecting plate 122 is used to connect the second shooting device 300. The third connecting plate 122 can only connect half of the second shooting device 300. The adjusting support 100 is compact in structure, small in size, and light in weight.

[0066] The second connecting plate 121 can include a heat dissipation part 1211. The heat dissipation part 1211 can have a flat surface that can be coated with thermal grease. The heat dissipation part 1211 is used for heat dissipation of the second shooting device 300.

[0067] Exemplarily, the second connecting plate 121 comprises a thickened portion 1212. The thickened portion 1212 can be thicker than other positions of the second connecting plate 121. The waist hole 1201 is arranged in the thickened portion 1212. The thickened portion 1212 can be arranged with a groove towards one side of the first connecting frame 110, for arranging the elastic member 4, so as to constrain the elastic member 4 and provide a longer stroke, and the elastic member 4 can be in a better deformed state.

[0068] With reference to Figure 1 The application provides a multi-lens holder 1100, which comprises a first shooting device 200, a second shooting device 300 and the adjusting support 100. The adjusting support 100 is used for connecting the first shooting device 200 to the second shooting device 300, and can also adjust and fix the optical axes of the two shooting devices to be parallel. The multi-lens holder 1100 has low maintenance cost and is convenient to use, and can be used in the field of unmanned aerial vehicle mounting.

[0069] Exemplarily, the first shooting device 200 is a zoom lens, and the second shooting device 300 is a laser ranging module, so that the two shooting devices can be used for accurate ranging. Exemplarily, the second shooting device 300 can be an infrared ranging module.
