Description

Technical Field

[0001] This invention relates to a camera housing assembly, an airborne camera, and a drone. Background Technology

[0002] Currently, drones on the market are equipped with multi-axis cameras. These cameras adjust their shooting direction and angle via internal motors to achieve image compensation. However, these cameras lack IPX4 waterproofing, making them susceptible to water ingress during rainy weather, which can cause motor malfunctions and prevent the camera from adjusting its shooting direction and angle to compensate for image damage. Therefore, researchers in this field are working to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a camera housing assembly, an airborne camera, and a drone that can prevent rainwater from easily entering the camera and causing motor malfunction.

[0004] An embodiment of the present invention discloses a camera housing assembly comprising an attachment mechanism, a lens carrier, and an annular water-blocking member. The lens carrier is rotatably disposed on the attachment mechanism, and the attachment mechanism and the lens carrier together form a motor housing space, an annular water-blocking space, and an annular slit. The annular water-blocking space surrounds the motor housing space, and the annular slit communicates with the annular water-blocking space. The annular water-blocking member is disposed in the annular water-blocking space and blocks the annular slit.

[0005] Another embodiment of the present invention discloses an airborne camera, comprising a camera housing assembly, a lens assembly, and a first motor assembly. The camera housing assembly includes an attachment mechanism, a lens carrier, and a first annular water-blocking member. The lens carrier is rotatably disposed on the attachment mechanism, and the attachment mechanism and the lens carrier together form a first motor accommodating space, a first annular water-blocking space, and a first annular slit. The first annular water-blocking space surrounds the first motor accommodating space, and the first annular slit communicates with the first annular water-blocking space. The first annular water-blocking member is disposed in the first annular water-blocking space and blocks the first annular slit. The lens assembly is disposed on the lens carrier. The first motor assembly is disposed in the first motor accommodating space.

[0006] Another embodiment of the present invention discloses a drone, comprising a flight vehicle and an airborne camera. The airborne camera includes a camera housing assembly, a lens assembly, and a first motor assembly. The camera housing assembly includes an attachment mechanism, a lens carrier, and a first annular water-blocking member. The attachment mechanism is mounted on the flight vehicle. The lens carrier is rotatably disposed on the attachment mechanism, and the attachment mechanism and the lens carrier together form a first motor receiving space, a first annular water-blocking space, and a first annular slit. The first annular water-blocking space surrounds the first motor receiving space, and the first annular slit communicates with the first annular water-blocking space. The first annular water-blocking member is disposed in the first annular water-blocking space and blocks the first annular slit. The lens assembly is disposed on the lens carrier. The first motor assembly is disposed in the first motor receiving space.

[0007] According to the camera housing assembly, airborne camera, and drone disclosed in the above embodiments, the annular water-blocking component is set in the annular water-blocking space surrounding the motor housing space, and the annular slit connected to the annular water-blocking space is blocked. This can prevent rainwater from entering the motor housing space through the annular slit and the annular water-blocking space. Therefore, it can be ensured that the motor assembly in the motor housing space can still maintain normal operation even on rainy days, so that the shooting direction and angle of the camera can be adjusted to compensate for the image.

[0084] Please see Figure 1 . Figure 1 This is a perspective view of the unmanned aerial vehicle (UAV) disclosed according to a first embodiment of the present invention. In this embodiment, the UAV 1 includes a flight vehicle 10 and an airborne camera 20, the airborne camera 20 being disposed on the flight vehicle 10.

[0085] Next, please refer to Figure 2 and Figure 3 . Figure 2 for Figure 1 A stereoscopic image of the drone's onboard camera. Figure 3 for Figure 2 A three-dimensional sectional view of the airborne camera.

[0086] The airborne camera 20 includes a camera housing assembly 21, a lens assembly 22, and a first motor assembly 23. The camera housing assembly 21 includes an attachment mechanism 211, a lens carrier 212, and a first annular water-blocking member 213.

[0087] The attachment mechanism 211 includes an attachment seat 2111, a first support arm 2112, and a second support arm 2113. The attachment seat 2111 is mounted on the aircraft 10. One end of the first support arm 2112 is rotatably mounted on the attachment seat 2111, the second support arm 2113 is rotatably mounted on the other end of the first support arm 2112, and the lens carrier 212 is rotatably mounted on the other end of the second support arm 2113. The lens assembly 22 is mounted on the lens carrier 212.

[0088] In this embodiment, the rotation axis P1 of the first arm 2112 relative to the attachment seat 2111, the rotation axis P2 of the second arm 2113 relative to the first arm 2112, and the axis P3 of the lens carrier 212 relative to the second arm 2113 are, for example, perpendicular to each other. That is, the lens carrier 212 can rotate relative to the attachment seat 2111 via the three mutually perpendicular axes P1, P2, and P3 of the first arm 2112 and the second arm 2113, thereby adjusting the shooting direction and angle of the lens assembly 22.

[0089] Next, please refer to the following: Figure 3 and Figure 4 . Figure 4 for Figure 3 An enlarged plan view of region A of the airborne camera.

[0090] The lens carrier 212 and the second arm 2113 together form a first motor housing space S11, a first annular water-blocking space S12, and a first annular slit S13. A first motor assembly 23 is disposed in the first motor housing space S11 and is used to drive the lens carrier 212 to rotate relative to the second arm 2113. The first annular water-blocking space S12 surrounds the first motor housing space S11. The first annular slit S13 is radially connected, for example, but not limited to, to the side of the first annular water-blocking space S12 away from the first motor housing space S11. That is, the first annular water-blocking space S12 is radially located between the first annular slit S13 and the first motor housing space S11. The width W1 of the first annular slit S13 is, for example, greater than or equal to 0.4 mm and less than or equal to 1 mm, thereby ensuring a certain degree of waterproofing without affecting the rotational movement of the lens carrier 212 relative to the second arm 2113. It should be noted that the width W1 of the first annular slit S13 can be adjusted as needed.

[0091] In this embodiment, the camera housing assembly 21 may further include a first adhesive layer 214, a first drag-reducing element 215, and a first lubricating layer 216. Furthermore, one end of the second arm 2113 of the attachment mechanism 211 is provided with a first end face 21131, and the lens carrier 212 is provided with a second end face 2121. The first end face 21131 faces the second end face 2121, and a first annular slit S13 is formed between the first end face 21131 and the second end face 2121.

[0092] The first adhesive layer 214 is located in the first annular water-blocking space S12 and is disposed on the second support arm 2113. The first adhesive layer 214 has a first adhesive surface 2141, which is flush with the first end face 21131. The first annular water-blocking member 213 is made of, for example, rubber. The first annular water-blocking member 213 includes a first fixing portion 2131 and a first extension portion 2132 connected together. The first fixing portion 2131 includes a first central portion 21311 and two first end portions 21312. The two first end portions 21312 are respectively connected to two opposite sides of the first central portion 21311, and the two first end portions 21312 and the first central portion 21311 are in a straight line. The first fixing part 2131 includes a first central part 21311 and two first end parts 21312, which are bonded to the first adhesive surface 2141 of the first adhesive layer 214 and fixed to the second support arm 2113 by the first adhesive layer 214. One of the first end parts 21312 is aligned with and covers the first annular slit S13. The first extension part 2132 extends from the first central part 21311 toward the lens carrier 212. The first extension part 2132 and the first fixing part 2131 form a first acute angle θ1. The first acute angle θ1 is located on the side of the first extension part 2132 adjacent to the first annular slit S13, and the first acute angle θ1 is, for example, greater than or equal to 50 degrees and less than or equal to 70 degrees.

[0093] The first drag-reducing element 215 is, for example, a smooth adhesive tape, such as Teflon tape. The first drag-reducing element 215 is located in the first annular water-blocking space S12 and is disposed on the lens carrier 212, and the first lubricating layer 216 is disposed on the first drag-reducing element 215. The first extension 2132 of the first annular water-blocking element 213 abuts against the first drag-reducing element 215 through the first lubricating layer 216.

[0094] In this embodiment, by setting the first annular water-blocking member 213 in the first annular water-blocking space S12 surrounding the first motor housing space S11 and blocking the first annular slit S13 connected to the first annular water-blocking space S12, rainwater can be prevented from entering the first motor housing space S11 through the first annular slit S13 and the first annular water-blocking space S12. Therefore, it can be ensured that the first motor assembly 23 in the first motor housing space S11 can still maintain normal operation even on rainy days, so that the shooting direction and angle of the camera can be adjusted to compensate for the image.

[0095] In this embodiment, by having the first adhesive surface 2141 of the first adhesive layer 214 flush with the first end face 21131 of the second support arm 2113, and by having one of the first ends 21312 of the first fixing part 2131 of the first annular water-blocking member 213 aligned with and blocking the first annular slit S13, rainwater entering the first annular water-blocking space S12 from the first annular slit S13 is directly blocked by the first fixing part 2131 of the first annular water-blocking member 213, thereby further improving the waterproof effect.

[0096] It should be noted that the first adhesive surface 2141 of the first adhesive layer 214 is not limited to being flush with the first end face 21131 of the second arm 2113, and one of the first ends 21312 of the first fixing portion 2131 of the first annular water-blocking member 213 is not limited to being aligned with and covering the first annular slit S13. In other embodiments, the first adhesive surface of the first adhesive layer may not be flush with the first end face of the second arm, and one of the first ends of the first fixing portion of the first annular water-blocking member may not be aligned with the first annular slit, but rather aligned with the first annular slit by the included angle between the first fixing portion and the first extension portion of the first annular water-blocking member.

[0097] In this embodiment, the first extension 2132 and the first fixing part 2131 form a first acute angle θ1. The first acute angle θ1 is located on the side of the first extension 2132 adjacent to the first annular slit S13. The configuration of the first acute angle θ1, for example, is greater than or equal to 50 degrees and less than or equal to 70 degrees. This configuration can ensure that the first extension 2132 can prevent rainwater from entering the first motor accommodating space S11 from the first annular water-blocking space S12, while also preventing the first extension 2132 from applying excessive positive force to the lens carrier 212. Therefore, the frictional force of the lens carrier 212 rotating relative to the second support arm 2113 can be reduced.

[0098] Furthermore, the aforementioned configuration of the first acute angle θ1 being greater than or equal to 50 degrees and less than or equal to 70 degrees can avoid the angle between the first extension 2132 and the first fixing part 2131 being too small, thus requiring the first annular water-blocking space S12 to accommodate the first annular water-blocking member 213, thereby maintaining the aesthetic appearance of the overall device.

[0099] It should be noted that the angle of the first acute angle θ1 can be adjusted as needed. In addition, the included angle between the first extension 2132 and the first fixing part 2131 adjacent to the first annular slit S13 is not limited to an acute angle, and may be an obtuse angle in other embodiments.

[0100] In this embodiment, the first central portion 21311 and the two first ends 21312 of the first fixing portion 2131 of the first annular water-blocking member 213 are all fixed to the second support arm 2113 by the first adhesive layer 214, which can enhance the strength of the first annular water-blocking member 213 fixed to the second support arm 2113.

[0101] It should be noted that the first fixing part 2131 of the first annular water-blocking member 213 is not limited to being fixed to the second support arm 2113 by the first adhesive layer 214, but in other embodiments it can be fixed to the second support arm 2113 in other suitable ways.

[0102] Furthermore, the first extension 2132 of the first annular water-blocking member 213 is not limited to extending from the first central portion 21311 of the first fixing portion 2131. In other embodiments, the first extension of the first annular water-blocking member may extend from the end of the first fixing portion.

[0103] In this embodiment, the first drag-reducing element 215 and the first lubricating layer 216 can reduce the friction between the first extension 2132 of the first annular water-blocking member 213 and the lens support member 212, so as to facilitate the smooth rotation of the lens support member 212 relative to the second support arm 2113.

[0104] It should be noted that the number of the first drag-reducing element 215 is not limited to one, but can be adjusted according to the size of the gap between the first extension 2132 of the first annular water-blocking element 213 and the lens carrier 212, so as to ensure that the first extension 2132 of the first annular water-blocking element 213 can contact the first drag-reducing element 215 to provide a waterproof effect.

[0105] Furthermore, the first drag-reducing element 215 and the first lubricating layer 216 are optional components and coatings. If the rotational force provided by the first motor assembly 23 is sufficient, the first drag-reducing element 215 and the first lubricating layer 216 can be omitted, and the first drag-reducing element 215 can directly contact the lens carrier 212.

[0106] In this embodiment, the first fixing portion 2131 of the first annular water-blocking member 213 is fixed to the second support arm 2113, while the first extension portion 2132 extends toward the lens support member 212, but is not limited thereto. In other embodiments, the first fixing portion of the first annular water-blocking member may be fixed to the lens support member, while the first extension portion extends toward the second support arm.

[0107] Next, please refer to the following: Figure 3 and Figure 5 . Figure 5 for Figure 3 A magnified plan view of area B of the airborne camera.

[0108] In this embodiment, the airborne camera 20 may further include a second motor assembly 24, and the camera housing assembly 21 may further include a second annular water-blocking component 217.

[0109] The first arm 2112 and the attachment seat 2111 together form a second motor housing space S21, a second annular water-blocking space S22, and a second annular slit S23. The second motor assembly 24 is disposed in the second motor housing space S21 and is used to drive the first arm 2112 to rotate relative to the attachment seat 2111. The second annular water-blocking space S22 surrounds the second motor housing space S21. The second annular slit S23 is radially connected, for example, but not limited to, to the side of the second annular water-blocking space S22 away from the second motor housing space S21. That is, the second annular water-blocking space S22 is radially located between the second annular slit S23 and the second motor housing space S21. The width W2 of the second annular slit S23 is, for example, greater than or equal to 0.4 mm and less than or equal to 1 mm.

[0110] In this embodiment, the camera housing assembly 21 may further include a second adhesive layer 218, a second drag-reducing element 219, and a second lubricating layer 220. Furthermore, one end of the first support arm 2112 is provided with a third end face 21121, and the attachment seat 2111 is provided with a fourth end face 21111. The third end face 21121 faces the fourth end face 21111, and a second annular slit S23 is formed between the third end face 21121 and the fourth end face 21111.

[0111] The second adhesive layer 218 is located in the second annular water-blocking space S22 and is disposed on the first support arm 2112. The second adhesive layer 218 has a second adhesive surface 2181, which is flush with the third end face 21121. The second annular water-blocking member 217 is, for example, made of rubber. The second annular water-blocking member 217 includes a connected second fixing portion 2171 and a second extension portion 2172. The second fixing portion 2171 includes a second central portion 21711 and two second end portions 21712. The two second end portions 21712 are respectively connected to opposite sides of the second central portion 21711, and the two second end portions 21712 and the second central portion 21711 are in a straight line. The second fixing portion 2171 includes a second central portion 21711 and two second end portions 21712, which are bonded to the second adhesive surface 2181 of the second adhesive layer 218 and fixed to the first support arm 2112 by the second adhesive layer 218. One of the second end portions 21712 is aligned with and covers the second annular slit S23. The second extension portion 2172 extends from the second central portion 21711 toward the attachment seat 2111. The second extension portion 2172 and the second fixing portion 2171 form a second acute angle θ2. The second acute angle θ2 is located on the side of the second extension portion 2172 adjacent to the second annular slit S23, and the second acute angle θ2 is, for example, greater than or equal to 50 degrees and less than or equal to 70 degrees.

[0112] The second drag-reducing element 219 is, for example, a smooth adhesive tape, such as Teflon tape. The second drag-reducing element 219 is located in the second annular water-blocking space S22 and is disposed on the attachment seat 2111, and the second lubricating layer 220 is disposed on the second drag-reducing element 219. The second extension 2172 of the second annular water-blocking member 217 abuts against the second drag-reducing element 219 through the second lubricating layer 220.

[0113] The effect of the structural configuration at the junction of the first arm 2112 and the attachment seat 2111 is similar to the effect of the structural configuration at the junction of the second arm 2113 and the lens carrier 212, so it will not be described again.

[0114] Next, please refer to the following: Figure 3 and Figure 6 . Figure 6 for Figure 3 A magnified plan view of region C of the airborne camera.

[0115] In this embodiment, the airborne camera 20 may further include a third motor assembly 25, and the camera housing assembly 21 may further include a third annular water-blocking component 221.

[0116] The second arm 2113 and the first arm 2112 together form a third motor housing space S31, a third annular water-blocking space S32, and a third annular slit S33. The third motor assembly 25 is disposed in the third motor housing space S31 and is used to drive the second arm 2113 to rotate relative to the first arm 2112. The third annular water-blocking space S32 surrounds the third motor housing space S31. The third annular slit S33 is radially connected, for example, but not limited to, to the side of the third annular water-blocking space S32 away from the third motor housing space S31. That is, the third annular water-blocking space S32 is radially located between the third annular slit S33 and the third motor housing space S31. The width W3 of the third annular slit S33 is, for example, greater than or equal to 0.4 mm and less than or equal to 1 mm.

[0117] In this embodiment, the camera housing assembly 21 may further include a third adhesive layer 222, a third drag-reducing element 223, and a third lubricating layer 224. Furthermore, one end of the second arm 2113 is provided with a fifth end face 21132, and one end of the first arm 2112 is provided with a sixth end face 21122. The fifth end face 21132 faces the sixth end face 21122, and a third annular slit S33 is formed between the fifth end face 21132 and the sixth end face 21122.

[0118] The third adhesive layer 222 is located in the third annular water-blocking space S32 and is disposed on the second support arm 2113. The third adhesive layer 222 has a third adhesive surface 2221, which is flush with the fifth end face 21132. The third annular water-blocking member 221 is made of rubber, for example. The third annular water-blocking member 221 includes a connected third fixing portion 2211 and a third extension portion 2212. The third fixing portion 2211 includes a third central portion 22111 and two third end portions 22112. The two third end portions 22112 are respectively connected to the opposite sides of the third central portion 22111, and the two third end portions 22112 and the third central portion 22111 are in a straight line. The third fixing portion 2211 includes a third central portion 22111 and two third end portions 22112, which are bonded to the third adhesive surface 2221 of the third adhesive layer 222 and fixed to the second support arm 2113 by the third adhesive layer 222. One of the third end portions 22112 is aligned with and covers the third annular slit S33. The third extension portion 2212 extends from the second central portion 21711 toward the first support arm 2112. The third extension portion 2212 and the third fixing portion 2211 form a third acute angle θ3. The third acute angle θ3 is located on the side of the third extension portion 2212 adjacent to the third annular slit S33, and the third acute angle θ3 is, for example, greater than or equal to 50 degrees and less than or equal to 70 degrees.

[0119] The third drag-reducing element 223 is, for example, a smooth adhesive tape, such as Teflon tape. The third drag-reducing element 223 is located in the third annular water-blocking space S32 and is disposed on the first support arm 2112, and the third lubricating layer 224 is disposed on the third drag-reducing element 223. The third extension 2212 of the third annular water-blocking member 221 abuts against the third drag-reducing element 223 through the third lubricating layer 224.

[0120] The effect of the structural configuration at the junction of the first arm 2112 and the second arm 2113 is similar to the effect of the structural configuration at the junction of the second arm 2113 and the lens carrier 212, so it will not be described again.

[0121] Next, please refer to Figure 7 , Figure 7 This is an enlarged plan view of region A of the airborne camera disclosed in the second embodiment of the present invention.

[0122] The airborne camera 20a of this embodiment is similar to the airborne camera 20 of the above embodiment. The main difference between the two lies in the structure of the annular water-blocking component. The following mainly illustrates the annular water-blocking component 213a in region A of the airborne camera 20a of this embodiment. As for other parts of this embodiment, please refer to the paragraphs of the foregoing embodiments and they will not be described again.

[0123] Figure 7 The area A of the airborne camera 20a shown corresponds to Figure 3 The area A shown is where the camera is mounted. Figure 7 Regarding region A of the airborne camera 20a shown, in this embodiment, one end of the extension 2132a of the annular water-blocking member 213a is connected to one end of the fixing part 2131a, and the other end of the extension 2132a is separated from the other end of the fixing part 2131a, so that the annular water-blocking member 213a is C-shaped, U-shaped, or V-shaped. An opening O is formed between the extension 2132a and the fixing part 2131a, and the opening O is aligned with the annular slit S13a.

[0124] In this embodiment, the annular water-blocking element 213a can also be applied to, for example... Figure 3 Regions B and C are shown.

[0125] Next, please refer to Figure 8 , Figure 8 This is an enlarged plan view of region A of the airborne camera disclosed in the third embodiment of the present invention.

[0126] The airborne camera 20b of this embodiment is similar to the airborne camera 20 of the above embodiment. The main difference between the two lies in the shape of the annular slit. The following mainly illustrates the annular slit S13b in region A of the airborne camera 20b of this embodiment. As for other parts of this embodiment, please refer to the paragraphs of the foregoing embodiments and they will not be described again.

[0127] Figure 8 The area A of the airborne camera 20b shown corresponds to Figure 3 The area A shown is where the camera is mounted. Figure 8 For region A of the airborne camera 20b shown, the annular slit S13b in this embodiment is an inclined slit and extends inclinedly toward the fixing part 2131b of the annular water-blocking member 213b, so that rainwater entering from the annular slit S13b can be stopped by the fixing part 2131b of the annular water-blocking member 213b.

[0128] In this embodiment, the inclined annular slit S13b can also be applied to, for example... Figure 3 Regions B and C are shown.

[0129] According to the camera housing assembly, airborne camera, and drone disclosed in the above embodiments, the annular water-blocking component is set in the annular water-blocking space surrounding the motor housing space, and the annular slit connected to the annular water-blocking space is blocked. This can prevent rainwater from entering the motor housing space through the annular slit and the annular water-blocking space. Therefore, it can be ensured that the motor assembly in the motor housing space can still maintain normal operation even on rainy days, so that the shooting direction and angle of the camera can be adjusted to compensate for the image.

[0130] Furthermore, by having the adhesive surface of the adhesive layer flush with one end face of the annular slit, and one end of the fixing part of the annular water-blocking member aligned with and blocking the annular slit, rainwater entering the annular water-blocking space from the annular slit can be directly blocked by the fixing part of the annular water-blocking member, thereby further improving the waterproof effect.

[0131] Furthermore, the configuration of the annular slit width being greater than or equal to 0.4 mm and less than or equal to 1 mm ensures a certain degree of waterproofing without affecting the rotational movement of the lens support, the second arm, and the first arm.

[0132] In addition, the extension of the annular water-blocking component forms an acute angle with the fixing part. The acute angle is located on the side of the extension adjacent to the annular slit, and the acute angle is greater than or equal to 50 degrees and less than or equal to 70 degrees. This configuration can ensure that the extension can prevent rainwater from entering the motor housing space from the annular water-blocking space, while also preventing the extension from applying excessive positive force. Therefore, it can reduce the friction of the lens support, the second arm and the first arm rotation.

[0133] Although the present invention has been disclosed above with reference to the preferred embodiments described above, it is not intended to limit the present invention. Those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims appended to this specification.
