Technical Field

[0001] The present application relates to the field of drone equipment, and in particular to a forensics module. Background Art

[0002] The evidence collection module is mounted on the drone. It includes visible light television, infrared thermal imager, servo platform, evidence collection module frame, video tracker and other modules, and has functions such as manual and automatic target tracking. The lenses of the visible light television and infrared thermal imager on the evidence collection module are located outside the frame of the evidence collection module, and the lenses can rotate with the frame to expand the recognition range. The evidence collection module can obtain various dynamic and static images, and then transmit them to the display device on the ground through the communication link so that the operator can control the flight of the drone.

[0003] When a drone flies in an area with high air humidity or enters a warm indoor environment from a cold outdoor environment, water vapor in the air will quickly condense on the lens surface to form fog, which will affect the recognition effect of the lens and easily affect the control of the drone.

[0006] By adopting the above technical solution, the driving component can drive the cleaning member to slide back and forth, thereby wiping the fog on the outer surface of the lens through the cleaning member, cleaning the lens, and helping to ensure the recognition effect of the lens; the electronic components inside the shell will generate heat when working, causing the air inside the shell to heat up, and the fan can discharge the hot air in the shell into the mounting shell when working, thereby heat dissipation inside the shell and ensuring the normal operation of the electronic components. The discharged hot air can also make the turntable rotate, thereby making the cleaning member slide, so that the discharged hot air can be reasonably utilized, so that the sliding of the cleaning member does not need to set up an additional power source, which is more energy-saving.

[0008] By adopting the above technical solution, the hot air in the shell flows into the interior of the mounting shell to push the windshield to rotate. When the windshield rotates, it drives the rotating rod to rotate, and the rotating rod drives the rotating disk to rotate, thereby driving the cleaning element.

[0010] By adopting the above technical scheme, the hot air in the mounting shell can flow into the airbag through the exhaust port, and then be discharged through the exhaust hole at the other end of the airbag, thereby discharging the heat; since the air intake in the airbag is greater than the air output, the airbag can be inflated so that the outer surface of the airbag is against the outer side of the lens, thereby achieving defog cleaning of the lens by the sliding airbag; in addition, the airbag can also wipe off dust and other debris adhering to the outer side of the lens, thereby ensuring the cleanliness of the lens surface and helping to ensure the recognition effect; since the airbag is flexible, the airbag can fully contact the lens, thereby avoiding damage to the lens and ensuring the cleaning effect of the lens; since the air introduced into the airbag is hot air, when the airbag is against the lens, the hot air inside the airbag can exchange heat with the outer surface of the lens, causing the outer surface of the lens to heat up, thereby making the temperature of the lens surface higher than the dew point temperature, preventing further condensation of water vapor.

[0011] Optionally, the outer side of the airbag is provided with fluff for abutting against the outer surface of the lens.

[0012] By adopting the above technical solution, the arrangement of the fluff increases the contact area between the airbag and the lens, thereby further enhancing the cleaning effect on the lens; since the fluff is flexible, it can also protect the lens and is not easy to cause damage to the lens.

On the one hand, it can increase the discharge amount of hot air, and on the other hand, it can make the lens temperature rise, thereby further enhancing the defog effect; in addition, the hot air discharged through the air duct can also blow on the fluff and the surface of the air bag, dry the outer surface of the fluff and the air bag or blow off the adhered dust, thereby ensuring the cleaning effect of the fluff.

[0015] Optionally, the cleaning member includes a brush plate and bristles fixedly disposed on the brush plate, the brush plate and the slider are fixedly connected, and the bristles are used to abut against the outer surface of the lens.

[0016] By adopting the above technical solution, the surface of the lens can be cleaned by the bristles when the brush plate slides, thereby achieving defogging of the lens, which helps to ensure the recognition effect.

[0017] Optionally, a switching mechanism is provided in the mounting shell, and the switching mechanism includes a motor, a gear, a rack and a connecting pipe. The motor is provided on the mounting shell, the gear is connected to the output shaft end of the motor, the rack is slidably connected in the mounting shell, the rack is meshed with the gear, and the connecting pipe is fixedly connected to the rack. Both ends of the connecting pipe are open, and when one end of the connecting pipe is connected to the air inlet, the other end of the connecting pipe is connected to the exhaust port.

[0018] By adopting the above technical solution, when the end of the connecting pipe is staggered with the air inlet and the air outlet, the hot air entering the mounting shell can drive the wind shield to rotate, thereby causing the cleaning member to slide and achieve cleaning of the lens; when the cleaning is completed, the motor is started to drive the connecting pipe to slide, so that the two ends of the connecting pipe are respectively connected to the air inlet and the air outlet, so that the hot air entering the mounting shell can directly flow out through the connecting pipe and the air outlet.

[0019] Optionally, the connecting tube includes a first tube body and a second tube body fixedly connected to both ends of the first tube body, wherein one of the second tube bodies is used to connect with the air inlet, and the other of the second tube bodies is used to connect with the air outlet, and the first tube body is located outside the air inlet and the air outlet.

[0020] By adopting the above technical solution, since the first tube body is located on the outside of the air inlet and the air outlet, the first tube body is not easy to block the air outlet. When the two second tube bodies are staggered with the air inlet and the air outlet respectively, the hot air in the installation shell can flow out smoothly through the air outlet, which helps to ensure the exhaust effect.

[0021] Optionally, a counterweight block is provided on the sliding block.

[0022] By adopting the above technical solution, when the cleaning member is in a stationary state, the slider is on the lower side, so that the cleaning member is located on the lower side.

[0026] 2. When the airbag is inflated, it presses against the surface of the lens. On the one hand, it can clean the lens. On the other hand, the hot air in the airbag can exchange heat with the lens surface, thereby heating up the lens. The temperature of the lens can be higher than the dew point temperature of the surrounding air, further reducing the possibility of water vapor condensation.

[0027] 3.

[0030] The following combination Figure 1-Figure 9 This application is described in further detail.

[0031] Example 1 The present application embodiment discloses a forensics module. Figure 1The evidence collection module includes an optoelectronic turret, a vibration reduction mechanism and a quick release mechanism, which are arranged from bottom to top. The vibration reduction mechanism is connected between the quick release mechanism and the optoelectronic turret, and the quick release mechanism is connected to the drone, so it is convenient to install and remove the optoelectronic turret. The optoelectronic turret is used to detect, identify and track the target, and the vibration reduction mechanism can reduce the impact of vibration on the optoelectronic turret, which helps to ensure the identification effect.

[0032] The optoelectronic turret includes a mounting base 1 and a shell 2. The mounting base 1 includes an azimuth motor 11, a U-shaped frame 12 and a pitch motor 13. In this embodiment, the output end rotation axis of the azimuth motor 11 is vertically arranged as an example for explanation, and the U-shaped frame 12 is fixedly connected to the output end of the azimuth motor 11; the fixed end of the pitch motor 13 is fixedly connected to the U-shaped frame 12, and the output end of the pitch motor 13 is fixedly connected to the shell 2. Therefore, with the cooperation of the azimuth motor 11 and the pitch motor 13, the range of rotation of the shell 2 around the vertical axis is -140° to +140°, and the range of rotation of the shell 2 around the horizontal axis is -110° to +10° (horizontal is 0°, and upward rotation is positive).

[0033] An infrared thermal imager 3 and a visible light television 4 are fixedly installed in the shell 2. The infrared thermal imager 3 is used to identify targets during the day, and the visible light television 4 is used to identify targets at night. The lenses of the infrared thermal imager 3 and the visible light television 4 are both located on the outside of the shell 2, and a mounting hole 23 for the lens to extend out is opened on the shell 2.

[0034] A fan 5 is also fixedly mounted on the housing 2. An air inlet 21 is provided on one side of the housing 2, and an air outlet 22 is provided on the other side of the housing 2. Therefore, when working, the heat generated by the electronic components in the housing 2 is dissipated into the air, causing the air temperature inside the housing 2 to rise. After the fan 5 is started, the air flow inside the housing 2 can be accelerated, so that the hot air in the housing 2 is discharged through the air outlet 22, thereby enhancing the heat dissipation effect. A waterproof and breathable membrane is fixedly provided on the housing 2 at the air inlet 21, thereby enhancing the waterproofness of the housing 2, thereby protecting the electronic components inside the housing 2.

[0035] Reference Figure 2 The housing 2 is also provided with a cleaning mechanism 6, which includes a cleaning member 61, a driving assembly 62 and a power assembly 63. The cleaning member 61 is slidably provided on the outer wall of the housing 2, and one side of the cleaning member 61 can abut against the outer surface of the lens, so that the cleaning member 61 can slide back and forth to clean the lens, thereby wiping off the fog on the lens, which helps to ensure the recognition effect.

[0036] Reference Figure 2 and Figure 3The driving assembly 62 is used to drive the cleaning member 61 to slide, and the driving assembly 62 includes a mounting shell 621, a rotating disk 622, a slider 623 and a connecting rod 624. The mounting shell 621 is fixedly connected to the outer wall of the housing 2, and the rotating disk 622 and the slider 623 are both located inside the mounting shell 621; the rotating disk 622 is rotatably connected to the inner wall of the mounting shell 621, and the slider 623 is slidably connected to the inner wall of the mounting shell 621, and the sliding direction of the slider 623 is parallel to the sliding direction of the cleaning member 61; the slider 623 is fixedly connected to the cleaning member 61. The connecting rod 624 is located inside the mounting shell 621, one end of the connecting rod 624 is hinged to the edge of the rotating disk 622, and the other end of the connecting rod 624 is hinged to the slider 623, and the hinge axes at both ends of the connecting rod 624 are parallel to the axis of the rotating disk 622. Therefore, when the rotating disk 622 rotates, the connecting rod 624 can drive the slider 623 to slide, and the slider 623 drives the cleaning member 61 to slide, thereby wiping off the fog on the outer surface of the lens.

[0037] The power assembly 63 is used to drive the turntable 622 to rotate, and the power assembly 63 includes a rotating rod 631 and a wind shield 632. The rotating rod 631 is located in the mounting shell 621, and the rotating rod 631 and the rotating disk 622 are coaxially fixedly connected; the wind shield 632 is fixedly connected to the rotating rod 631, and a plurality of wind shields 632 are provided and arranged in a circular array. The mounting shell 621 is provided with an air inlet 6211 and an air outlet 6212, and the air inlet 6211 and the air outlet 6212 are located on the same side of the mounting shell 621. The air inlet 6211 on the mounting shell 621 is connected to the air outlet 22 on the shell 2, so that the hot air in the shell 2 flows into the mounting shell 621 through the air outlet 22 and the air inlet 6211, and the wind shield 632 can be driven to rotate, and the wind shield 632 drives the rotating rod 631 to rotate, thereby rotating the turntable 622.

[0038] Two groups of cleaning members 61 are provided, one of which is used to clean the lens of the infrared thermal imager 3, and the other cleaning member 61 is used to clean the lens of the visible light television 4. The cleaning member 61 includes a mounting block 611 and an airbag 612. The airbag 612 is in the shape of a long strip, and two mounting blocks 611 are provided and are fixedly connected to the two ends of the airbag 612 respectively. A support rod 6113 is fixedly connected between the mounting blocks 611 at the ends of the two airbags 612, and a guide frame 24 is fixedly connected to the outer wall of the housing 2. The support rod 6113 is slidably inserted into the guide frame 24, so that the mounting block 611 and the airbag 612 are slidably arranged. A support plate 6111 is fixedly connected between the mounting blocks 611 at both ends of each airbag 612, and a connecting rod 6112 is fixedly connected between one mounting block 611 and the slider 623; an avoidance groove 6213 is opened on the mounting shell 621, and the connecting rod 6112 slides through the avoidance groove 6213, so that the two mounting blocks 611 at both ends of the airbag 612 can slide synchronously.

[0039] Reference Figure 4 and Figure 5 The mounting blocks 611 at both ends of the airbag 612 are provided with cavities inside, and the two ends of the airbag 612 are respectively connected with the cavities inside the two mounting blocks 611. An exhaust hole 8 is provided on the mounting block 611 on the side away from the mounting shell 621, and the cavity inside the mounting block 611 on the side close to the mounting shell 621 is connected with the exhaust port 6212 on the mounting shell 621 through a hose 9. Therefore, the hot air in the mounting shell 621 can flow into the hose 9 through the exhaust port 6212, and then flow into the airbag 612, so that the airbag 612 swells, so that the airbag 612 is against the outer surface of the lens, so that the airbag 612 can wipe the fog on the lens when sliding with the mounting block 611. Fluff is fixedly provided on the outer surface of the airbag 612 on the side away from the support plate 6111, and the fluff can be against the lens, so as to enhance the cleaning effect of the fog on the lens.

[0040] Reference Figure 2 A baffle 10 is fixedly connected to the connecting rod 6112, and the baffle 10 abuts against the outer wall of the mounting shell 621 at the avoidance groove 6213. Therefore, during the sliding process of the connecting rod 6112, the baffle 10 always blocks the outside of the avoidance groove 6213, so that the hot air in the mounting shell 621 can be discharged through the exhaust port 6212.

[0041] Reference Figure 6 Furthermore, an air duct 6114 is fixedly connected to the mounting block 611, and the air duct 6114 is connected to the cavity inside the mounting block 611, and the opening of the air duct 6114 faces the fluff on the air bag 612. Therefore, the hot air entering the cavity inside the mounting block 611 can not only flow into the air bag 612, but also be discharged through the air duct 6114, so that the lens is heated up, making it difficult for fog to form on the lens.

[0042] Reference Figure 7 , Figure 8 and Fig. 9 When the cleaning process of the lens is completed, the cleaning member 61 can stop sliding. In order to allow the hot air in the housing 2 to be discharged smoothly at this time, thereby achieving heat dissipation, a switching mechanism 7 is also provided in the mounting shell 621. The switching mechanism 7 includes a motor 71, a gear 72, a rack 73 and a connecting pipe 74. The motor 71 is fixedly connected to the outer wall of the mounting shell 621, and the gear 72 is located in the mounting shell 621. The gear 72 is coaxially fixedly connected to the end of the output shaft of the motor 71. The rack 73 is slidably connected to the inner wall of the mounting shell 621, and the rack 73 is meshed with the gear 72. The side of the rack 73 away from the gear 72 is fixedly connected to the connecting pipe 74.

[0043] The connecting tube 74 includes a first tube body 741 and a second tube body 742; the rack 73 is fixedly connected to the outer wall of the first tube body 741, and two second tube bodies 742 are provided and fixedly connected to the two ends of the first tube body 741. One of the second tube bodies 742 is used to communicate with the air inlet 6211, and the other second tube body 742 is used to communicate with the air outlet 6212. When one of the second tube bodies 742 is connected with the air inlet 6211, the other second tube body 742 is in a connected state with the air outlet 6212; when one of the second tube bodies 742 is staggered with the air inlet 6211, the other second tube body 742 is staggered with the air outlet 6212.

[0044] Therefore, after the motor 71 is started, the gear 72 can be rotated, the gear 72 drives the rack 73 to slide, and the rack 73 drives the connecting pipe 74 to slide, thereby realizing the switching of the exhaust state. When it is necessary to defog and clean the lens, the end of the connecting pipe 74 is staggered with the air inlet 6211 and the air outlet 6212, and the connecting pipe 74 is in a closed state. At this time, the hot air entering the mounting shell 621 can drive the wind shield 632 to rotate, thereby making the cleaning member 61 slide, thereby realizing the cleaning of the lens. After the cleaning is completed, the motor 71 is started, and the position of the connecting pipe 74 is adjusted so that the two ends of the connecting pipe 74 are connected between the air inlet 6211 and the air outlet 6212, so that the hot air entering the mounting shell 621 can flow into the cavity inside the mounting block 611 and the air bag 612 through the connecting pipe 74, and then discharged through the air guide 6114 on the mounting block 611 and the exhaust hole 8 on the air bag 612.

[0045] Furthermore, a counterweight is provided on the slider 623, so that when the cleaning member 61 stops sliding, the counterweight can cause the slider 623 to move downward, thereby causing the cleaning member 61 to slide downward, causing the cleaning member 61 to slide to the outside of the lens, reducing the blocking of the lens by the cleaning member 61, thereby ensuring the recognition effect.

[0046] The implementation principle of Example 1 is as follows: the photoelectric turret is installed on the UAV. When the UAV is in working state, the electronic devices in the photoelectric turret are in working state. The electronic devices will generate heat when working. Therefore, after the fan 5 is started, the circulation of air inside the shell 2 can be accelerated, so that the hot air inside the shell 2 is discharged through the air outlet 22, thereby achieving heat dissipation inside the shell 2.

[0047] In the initial state, the end of the connecting tube 74 is staggered with the air inlet 6211 and the air outlet 6212. The hot air discharged from the housing 2 flows into the mounting shell 621 through the air inlet 6211. The hot air flowing into the mounting shell 621 can drive the windshield 632 to rotate, so that the rotating rod 631 rotates, and the rotating rod 631 drives the rotating disk 622 to rotate. The rotating disk 622 drives the slider 623 to slide through the connecting rod 624. The slider 623 drives the mounting block 611 to slide through the connecting rod 6112. The mounting block 611 drives the airbag 612 to slide, so that the airbag 612 slides back and forth. The hot air flowing into the mounting shell 621 drives the windshield 632 to rotate and then flows into the cavity inside the mounting block 611 through the air outlet 6212, and then flows into the inside of the airbag 612, so that the airbag 612 bulges, and the fluff on the outer surface of the airbag 612 abuts against the outer surface of the lens. Therefore, the reciprocating airbag 612 can wipe the fog on the lens and remove the dust on the lens, which helps to ensure the recognition effect of the lens. When the airbag 612 cleans the lens, part of the air in the internal cavity of the mounting block 611 can be discharged through the air duct 6114, and then hot air is blown to the surface of the lens, thereby heating the lens and helping to enhance the defogging effect on the lens.

[0048] After the cleaning process of the lens is completed, the motor 71 is started, so that the gear 72 rotates, the rack 73 slides, and the rack 73 drives the connecting tube 74 to slide, so that the two ends of the connecting tube 74 are respectively connected with the air inlet 6211 and the air outlet 6212. At this time, the hot air entering the mounting shell 621 can directly flow into the mounting block 611 and the air bag 612 through the connecting tube 74, and then the hot air is discharged through the air guide 6114 and the exhaust hole 8. In this state, the mounting block 611 and the air bag 612 are both in a static state, and the mounting block 611 and the air bag 612 are both located below the corresponding lens, so the air bag 612 is not easy to block the lens, which helps to ensure the field of view.

[0049] When the lens needs to be cleaned again, the motor 71 is started again to drive the connecting tube 74 to slide so that the end of the connecting tube 74 and the air inlet 6211 and the air outlet 6212 are offset.

[0050] Example 2 The difference between this embodiment and embodiment 1 is that the cleaning member 61 in this embodiment includes a brush plate and bristles, and the brush plate and the slider 623 are fixedly connected; the bristles are fixedly arranged on the brush plate, so that when the slider 623 slides back and forth, it can drive the brush plate and the bristles to slide, and when the bristles pressed against the surface of the lens slide, the surface of the lens can be cleaned, thereby wiping off the fog on the lens.

[0051] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
