[0049] The technical solution of the present invention is further described below through specific implementation modes in conjunction with the accompanying drawings.
[0050] A fully sealed structure for a pan / tilt pod, comprising: a pan / tilt base 1, a pan / tilt fixing frame 2, a pan / tilt rotating assembly 3, a pan / tilt front cover 5, a pan / tilt rear cover 4, a pan / tilt rotating frame 6 and a first sealing ring 71;
[0051] The gimbal fixing frame 2 is installed on the gimbal base 1; the gimbal rotating assembly 3 is installed on the gimbal fixing frame 2, and the gimbal front cover 5 is rotatably installed on the gimbal fixing frame 2 through the gimbal rotating assembly 3; the gimbal front cover 5 and / or the gimbal rear cover 4 are provided with a frame accommodating cavity 51 for accommodating the gimbal rotating frame 6; the gimbal front cover 5 and the gimbal rear cover 4 are cooperatively connected so that the gimbal rotating frame 6 is sealed and installed in the frame accommodating cavity 51; either the gimbal front cover 5 or the gimbal rear cover 4 is provided with a first sealing groove 52 at the cooperative position, and the other is provided with a first clamping surface 53 at the cooperative position; the first sealing ring 71 is arranged in the first sealing groove 52 and is clamped by the first clamping surface 53.
[0052] This fully sealed structure is used in the gimbal pod. By setting a first sealing ring 71 at the connection position of the gimbal front cover 5 and the gimbal rear cover 4, the interior of the gimbal front cover 5 and the gimbal rear cover 4 are effectively sealed, which can effectively protect the sealing of the interior of the gimbal, prevent external fluid from entering the gimbal, and prevent the fluid from affecting the normal use of the gimbal.
[0053] Specifically, the pan / tilt rotating assembly 3 is used to drive the pan / tilt front cover 5 to rotate, so that the pan / tilt front cover 5 and the pan / tilt rear cover 4 rotate with the X axis as the axis center, driving the pan / tilt rotating frame 6 in the frame accommodating cavity 51 to rotate, and the pan / tilt rotating frame 6 is used to carry the pan / tilt movement 85 of the pan / tilt, thereby rotating the pan / tilt movement 85 so that the pan / tilt can monitor multiple angles. Since the first sealing ring 71 is arranged between the pan / tilt front cover 5 and the pan / tilt rear cover 4, as shown in FIG. Figure 5 A first sealing groove 52 which is closed at both ends is provided on the front cover 5 of the middle gimbal, and a first sealing ring 71 is arranged in the first sealing groove 52. Since the gimbal movement 85 is arranged in the front cover 5 of the gimbal and the rear cover 4 of the gimbal, the first sealing ring 71 between the front cover and the rear cover can increase the sealing between the two.
[0054] Preferably, the pan / tilt rotating assembly 3 comprises: a rotating connecting bearing 31, a rotating connecting block 32 and a rotating shaft 33;
[0055] The rotating connection bearing 31 is installed on the pan / tilt fixing frame 2; the rotating connection block 32 is installed on the pan / tilt front cover 5;
[0056] The rotating shaft 33 is matched with the rotating connection bearing 31 and fixed to the rotating connection block 32 ; the pan head front cover 5 drives the pan head rotating frame 6 to rotate around the rotating shaft 33 as the axis.
[0057] Under the driving action of the rotating driver 34 , the rotating shaft 33 rotates on the rotating connecting bearing 31 , and drives the rotating connecting block 32 to rotate, so that the pan head front cover 5 and the pan head rear cover 4 rotate, and further drives the pan head movement 85 to rotate.
[0058] Preferably, it also includes: a second sealing filler;
[0059] The side of the pan / tilt front cover 5 and / or the pan / tilt rear cover 4 is provided with a cable outlet 54; the rotating connecting block 32 is provided with a through-shaft groove 321 at the connecting position between the rotating connecting block 32 and the rotating shaft 33; the interior of the rotating shaft 33 is through-core; the cable outlet 54, the through-shaft groove 321 and the through-core position of the rotating shaft 33 are connected, and the connected positions of the three are used to place wires;
[0060] The second sealing filler is filled in the cable outlet 54 to seal the cable outlet 54 .
[0061] The interior of the fully sealed structure requires a wire connection frame to connect the pan / tilt movement 85 in the accommodating cavity 51 and the external output device; therefore, a wire outlet 54 is required; the wire outlet 54, the through-shaft groove 321 and the interior of the rotating shaft 33 are connected, that is, one end of the wire is connected to the pan / tilt movement 85, and the other end passes through the wire outlet 54 and the through-shaft groove 321 in sequence, and then connected from the empty position of the rotating shaft 33. Since the wire is discharged from the through-center position of the rotating shaft 33, and the rotating shaft 33 cooperates with the rotating connecting bearing 31, the wire discharged from the empty position of the rotating shaft 33 will not be entangled, and will not affect the rotation of the pan / tilt front cover 5 and the pan / tilt rear cover 4.
[0062] At the same time, the second sealing filler is used for the cable opening 54, so that after the wires are arranged, the cable opening 54 is sealed, thereby ensuring that the external medium does not enter the inside of the pan / tilt from the cable opening 54, thereby improving the sealing of the inside of the pan / tilt. Specifically, the second sealing filler is a well-known filler, such as cotton, particles or sealant, etc. Preferably, sealant is used, and the sealant is applied to the cable opening 54, and the sealant is fixed after curing, which not only fixes the wires to the cable opening 54, but also seals the cable opening 54, without having to consider whether the filler will loosen and fall off from the cable opening 54.
[0063] Preferably, it also includes: a third sealing ring 73;
[0064] The rotating connection block 32 is provided with a third sealing groove 322 at the connection position between the rotating connection block 32 and the pan / tilt front cover 5 ; the third sealing ring 73 is disposed in the third sealing groove 322 .
[0065] The third sealing ring 73 is arranged at the connection position between the rotating connection block 32 and the pan / tilt head front cover 5, which can further reduce the connection gap between the two, prevent the fluid from accumulating in the gap between the two, and reduce the possibility of it entering the interior of the pan / tilt head. On the basis that it is difficult for external fluid to enter the pan / tilt head front cover 5 through the position between the rotating connection block 32 and the pan / tilt head front cover 5, combined with the isolation of the second sealing filler, the sealing of the interior of the pan / tilt head can be greatly improved without affecting the distribution of the wires and the rotation of the rotating connection block 32, thereby protecting the interior of the pan / tilt head.
[0066] Preferably, the third sealing groove 322 is located on the outside of the through-shaft groove 321, surrounding the through-shaft groove 321. When the third sealing ring 73 is set in the third sealing groove 322, the external fluid will not enter the routing position of the rotating connecting block 32 from the through-shaft groove 321, further protecting the wires at the routing position.
[0067] Preferably, the rotating connection block 32 and the rotating shaft 33 are integrally formed and combined.
[0068] The rotating connection block 32 and the rotating shaft member 33 are integrally formed, that is, the rotating connection block 32 and the rotating shaft member 33 are sealed and fixed, and there is no need to consider the connection gap between the two. After the wire is directly discharged from the wire outlet 54 of the pan / tilt front cover 5, it enters the through-axis position of the rotating shaft member 33 through the through-axis groove 321, thereby improving the sealing performance; and because the rotating connection block 32 and the rotating shaft member 33 are integrally formed, when the rotating shaft member 33 rotates, it can directly drive the rotating connection block 32 to rotate, and there is no need to consider fixing the two by clamping, which effectively avoids the connection gap caused by the clamping and prevents the clamping structure from easily entering water.
[0069] Preferably, the through-shaft groove 321 is provided with a displaced inner recess 323 at the contact position between the rotating connection block 32 and the pan / tilt front cover 5; the opening position of the displaced inner recess 323 faces the cable outlet 54;
[0070] The through-shaft groove 321 is provided with a shaft connection opening 324 at the position of the rotating shaft 33; the shaft connection opening 324 is connected to the through-center position of the rotating shaft 33;
[0071] The axis of the cable outlet 54 and the axis of the shaft connecting opening 324 form a distance difference.
[0072] The offset inner recess 323 is used for routing the wires; after the wires are output from the wire discharge port 54, they are transmitted from the shaft connection port 324 to the through-center position in the rotating shaft 33 through the offset inner recess 323. Since the axis of the wire discharge port 54 and the axis of the shaft connection port 324 form a distance difference, that is, a horizontal distance difference and / or a vertical distance difference, the wires located at the wire discharge port 54 and the wires located at the shaft connection port 324 are offset. If the external fluid needs to pass through the turning position between the rotating shaft 33 and the through-axis groove 321 in sequence, then pass through the turning position between the offset inner recess 323 and the wire discharge port 54, and then enter the inside of the pan-tilt head from the wire discharge port 54, since the rotating shaft 33 and the wire discharge port 54 are offset, the probability that the fluid cannot enter the inside of the pan-tilt head in this case is low. The second sealing filler on the wire discharge port 54 can greatly improve the sealing performance inside the pan-tilt head.
[0073] Preferably, it also includes: a gimbal side cover 74; the gimbal side cover 74 is arranged on both sides of the gimbal fixing frame 2 and covers the outer side of the gimbal rotating assembly 3.
[0074] The gimbal side cover 74 surrounds the outside of the gimbal rotating assembly 3, which can greatly protect the gimbal rotating assembly 3 and play a secondary protection role; if a small part passes through the gimbal side cover 74 and leaks into the interior of the gimbal side cover 74, the fluid needs to break through the first sealing ring 71, the second sealing filler and the third sealing ring 73 before it can enter the interior of the gimbal to affect the gimbal movement 85.
[0075] Preferably, the pan-tilt rotating assembly 3 includes: a rotation driver 34; the rotation driver 34 is installed on the pan-tilt fixing frame 2, and its output end is connected to the pan-tilt front cover 5 for driving the pan-tilt front cover 5 to rotate.
[0076] The pan-tilt rotation driver 34 is used to drive the pan-tilt front cover 5 to rotate, so that the pan-tilt front cover 5 rotates around the X-axis to achieve an automatic rotation effect; a rotating shaft 33 is provided on one side of the pan-tilt front cover 5, and a rotating driver 34 is provided on the other side; when the rotating driver 34 is started, the pan-tilt front cover 5 can rotate under the guidance of the rotating connecting bearing 31 and the rotating shaft 33.
[0077] The rotation driver 34 can be replaced by an existing device that can achieve rotation, preferably a motor, and the output end of the motor is connected to the pan-tilt head front cover 5 to drive the pan-tilt head front cover 5 to rotate.
[0078] Preferably, it also includes: a lens sealing assembly 8 and a pan / tilt movement 85;
[0079] The lens sealing assembly 8 comprises: a transparent sheet 82, a clamping ring 83, a movement sealing ring 84 and a lens sealing ring 86;
[0080] The pan / tilt front cover 5 is provided with a lens hollow slot 811;
[0081] A lens sealing groove 812 is provided at the bottom of the lens hollow groove 811; the lens sealing ring 86 is installed in the lens sealing groove 812; the transparent sheet 82 is provided in the lens hollow groove 811, and its bottom contacts the lens sealing ring 86; the clamping ring 83 is fixed to the lens hollow groove 811, and its bottom presses the transparent sheet 82; the movement sealing ring 84 is provided in the lens hollow groove 811, and its bottom contacts the clamping ring 83; the gimbal movement 85 is installed on the gimbal rotating frame 6; the gimbal movement 85 is provided with a columnar gimbal lens 851, and the gimbal lens 851 extends into the lens hollow groove 811; the inner circle of the movement sealing ring 84 surrounds the outer side of the gimbal lens 851, and the outer circle contacts the inner wall of the lens hollow groove 811.
[0082] The lens sealing assembly 8 is used for the pan / tilt head lens 851 part, which can seal the lens part to prevent external moisture from entering the inside of the pan / tilt head, thereby effectively improving the sealing performance of the pan / tilt head.
[0083] Specifically, the pan head front cover 5 is provided with a lens hollow groove 811, the bottom of the lens hollow groove 811 is hollow, and a transparent sheet 82 is arranged at the position of the lens hollow groove 811 to isolate the hollow position of the lens hollow groove 811; the clamping ring 83 is fixed in the lens hollow groove 811, and compresses the transparent sheet 82 to fix the transparent sheet 82 and prevent it from loosening. The pan head lens 851 of the pan head movement 85 extends into the lens hollow groove 811, which is used to isolate the transparent sheet 82 and monitor or shoot the scene outside the pan head front cover 5; the movement sealing ring 84 covers the pan head lens 851, and the outer side of the pan head lens 851 opens the movement sealing ring 84. Since the outer ring of the movement sealing ring 84 contacts the side wall of the lens hollow groove 811, the sealing performance inside the pan head is further improved. At the same time, under the driving action of the pan head rotating assembly 3, the pan head movement 85 rotates with the pan head rotating frame 6, achieving the effect of rotating in a sealed state, and it is not easy for water to enter the pan head during the rotation process. The rotation limiting piece 75 is used to contact the outside of the lens hollow groove 811 to support the outside of the lens hollow groove 811 so that the lens hollow groove 811 can be positioned after rotation.
[0084] The transparent sheet 82 is made of a transparent material that is light-transmissive and may be preferably a glass sheet.
[0085] The lens seal ring 86 is arranged in the lens hollow groove 811. Under the pressure of the clamping ring 83, the bottom of the transparent sheet 82 presses the movement seal ring 84, further strengthening the sealing between the pan head front cover 5 and the transparent sheet 82, preventing moisture from entering from the position between the pan head front cover 5 and the transparent sheet 82, and ensuring the sealing inside the pan head. The lens seal ring 86 can be preferably elastic. When the transparent sheet 82 is pressed downward, the lens seal ring 86 deforms itself, so that the bottom of the transparent sheet 82 can press the lens seal ring 86 and can contact the outer end 813 of the notch at the notch of the lens hollow groove 811, thereby strengthening the sealing of the lens seal ring 86. The outer end 813 of the notch is a horizontal surface outside the notch of the lens hollow groove 811.
[0086] The lens sealing ring 86 is elastic; the bottom of the transparent sheet 82 presses the outer end 813 of the lens sealing groove 812 .
[0087] The first pressing holes 871 are distributed in an annular shape on the outer ring of the pressing ring 83. The first pressing holes 871 are distributed in an annular shape, which can make the fixing force of the pressing fixture 87 more uniform, prevent the transparent sheet 82 from being partially broken due to strong force, and increase the service life of the transparent sheet 82.
[0088] The clamping fixture 87 is located in the lens hollow groove 811 . The clamping fixture 87 is located in the lens hollow groove 811, which means that the clamping fixture 87 will extend into the lens hollow groove 811; including the following two situations: the clamping fixture 87 passes through the second clamping hole 872 and the first clamping hole 871 from the outside to the inside from the outside of the gimbal front cover 5, and is matched with the first clamping hole 871; or the clamping fixture 87 is located inside the gimbal front cover 5, and passes through the first clamping hole 871 and the second clamping hole 872 in sequence, and is matched with the second clamping hole 872. This embodiment can hide the clamping fixture 87 inside the gimbal front cover 5, avoiding the presence of the clamping fixture 87 outside the gimbal front cover 5, improving the beauty and simplicity of the outside of the gimbal, and preventing moisture residue; the clamping fixture 87 is preferably a bolt with an external thread structure; the second clamping hole 872 is a hole with an internal thread structure; the clamping fixture 87 is installed in the second clamping hole 872 by threaded matching.
[0089] The pan-tilt movement 85 is provided with a movement horizontal end surface 852; the pan-tilt lens 851 is arranged on the movement horizontal end surface 852; the movement horizontal end surface 852 contacts the upper surface of the movement sealing ring 84. The fixed end of the pan-tilt movement 85 is inside the pan-tilt front cover 5, such as the pan-tilt rotating frame fixed inside the pan-tilt front cover 5; when the pan-tilt lens 851 extends into the lens hollow groove 811, the movement horizontal end surface 852 contacts (presses) the upper surface of the movement sealing ring 84, reducing the contact gap between the pan-tilt movement 85 and the movement sealing ring 84, and reducing the moisture from entering the pan-tilt from the gap; with the sealing effect of the lens sealing ring 86, the sealing performance of the pan-tilt can be greatly improved, and it is basically difficult for moisture to enter the lens sealing ring 86, and if it enters, it is also difficult to enter the movement sealing ring 84.
[0090] The movement seal ring 84 is elastic, and the diameter of its inner ring is not larger than the outer diameter of the pan-tilt lens 851. Although the inner ring diameter of the movement seal ring 84 is smaller than the outer diameter of the pan-tilt lens 851, the movement seal ring 84 can cover the outer part of the pan-tilt lens 851 through elastic deformation, thereby fixing the pan-tilt lens 851 and preventing moisture from entering the pan-tilt through the movement seal ring 84, thereby improving the sealing performance.
[0091] The lens sealing assembly 8 further includes: a pressing fixture 87; the outer ring of the pressing ring 83 is provided with a first pressing hole 871; the lens hollow groove 811 is provided with a second pressing hole 872 at a position corresponding to the first pressing hole 871; the pressing fixture 87 connects the first pressing hole 871 and the second pressing hole 872. The pressing fixture 87 fixes the pressing ring 83 in the lens hollow groove 811, so that the transparent sheet 82 can press the bottom of the lens hollow groove 811, or press the transparent sheet 82 against the lens sealing ring 86, thereby improving the fixing effect of the transparent sheet 82, and providing a pressing force to reduce the contact gap between the transparent sheet 82 and the lens hollow groove 811, thereby improving the sealing performance.
