Description

Technical Field

[0001] The present application relates to the field of monitoring equipment, and in particular to a hemispherical camera. Background Art

[0002] Infrared dome cameras are small in size and beautiful in appearance. When used in buildings, they can be well coordinated with the building environment, thus having a certain degree of concealment. Therefore, dome cameras are widely used in various internal occasions of buildings to monitor the target scene.

[0003] In the related art, a hemispherical camera has three rotation axes. When installing on site, the installer needs to adjust the attitude angle of the lens module of the hemispherical camera through the three rotation axes so that the installed hemispherical camera can shoot the target scene at a better angle. Most existing hemispherical cameras need to remove the outer shell in the process of adjusting the attitude angle of the lens module, which will cause water vapor in the air to invade the interior of the hemispherical camera. If the air humidity at the installation site is high, the water vapor will corrode the surface of the lens module and the video sensor, thereby affecting the imaging effect of the video. Therefore, there is an urgent need for a hemispherical camera that can adjust the attitude angle of the lens module in a sealed state. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide a hemispherical camera, which can adjust the attitude angle of the lens module while maintaining a sealed state. The specific technical solution is as follows:

[0005] The embodiment of the present application provides a hemispherical camera, comprising: a base; a body shell, the body shell being connected to the base in a manner rotatable around a first axis; an angle conversion mechanism, the angle conversion mechanism being arranged inside the body shell, the angle conversion mechanism comprising a bracket fixed to the body shell, a first movable part connected to the bracket in a manner rotatable around a second axis, and a second movable part connected to the first movable part in a manner rotatable around a third axis, the second axis being perpendicular to the first axis; a lens module, the lens module being fixedly connected to the second movable part, the third axis coinciding with the central axis of the lens module; a first adjustment component, the first adjustment component being connected to the first movable part, the A first adjusting component is used to adjust the rotation angle of the first movable part around the second axis; a first linkage adjusting shaft, the first linkage adjusting shaft passes through the fuselage shell and is sealed to the fuselage shell, and one end of the first linkage adjusting shaft located in the fuselage shell is transmission-connected to the first adjusting component; a second adjusting component, the second adjusting component is connected to the second movable part, and the second adjusting component is used to adjust the rotation angle of the second movable part around the third axis; a second linkage adjusting shaft, the second linkage adjusting shaft passes through the fuselage shell and is sealed to the fuselage shell, and one end of the second linkage adjusting shaft located in the fuselage shell is transmission-connected to the second adjusting component.

[0006] The hemispherical camera of the embodiment of the present application has a body shell connected to the base in a manner that can rotate around a first axis, that is, the body shell can rotate relative to the base, so the first axis is the first rotation axis of the hemispherical camera. The first movable part of the angle conversion mechanism is connected to the bracket in a manner that can rotate around a second axis, and the bracket is fixed to the body shell, thereby allowing the first movable part to rotate relative to the body shell, so the second axis is the second rotation axis of the hemispherical camera. In addition, the second movable part of the angle conversion mechanism is connected to the first movable part in a manner that can rotate around a third axis, and the lens module is fixed to the second movable part, thereby allowing the lens module to rotate relative to the first movable part, so the third axis is the third rotation axis of the hemispherical camera. By adjusting the rotation angles of each component around the above three rotation axes, the attitude angle of the lens module can be adjusted.

[0007] The installer can set the angle around the first rotation axis by rotating the body shell. In addition, the installer can rotate the first linkage adjustment shaft, which transmits the rotation to the first adjustment component, thereby setting the angle around the second rotation axis through the first adjustment component. Furthermore, the installer can rotate the second linkage adjustment shaft, which transmits the rotation to the second adjustment component, thereby setting the angle around the third rotation axis through the second adjustment component. Since the first linkage adjustment shaft and the second linkage adjustment shaft are both sealed to the body shell, the lens module is always in a sealed state during the process of adjusting the attitude angle of the lens module, thereby preventing water vapor in the air from invading the interior of the hemispherical camera.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0028] like Figures 1 to 4As shown, the embodiment of the present application proposes a hemispherical camera 10. The hemispherical camera 10 includes a base 100, a body shell 200, an angle conversion mechanism 300, a lens module 400, a first adjustment component 500, a second adjustment component 600, a first linkage adjustment shaft 700 and a second linkage adjustment shaft 800. Specifically, the body shell 200 is connected to the base 100 in a manner that it can rotate around a first axis L1. The angle conversion mechanism 300 is arranged inside the body shell 200, and the angle conversion mechanism 300 includes a bracket 310 fixed to the body shell 200, a first movable part 320 connected to the bracket 310 in a manner that it can rotate around a second axis L2, and a second movable part 330 connected to the first movable part 320 in a manner that it can rotate around a third axis L3, and the second axis L2 is perpendicular to the first axis L1. The lens module 400 is fixedly connected to the second movable part 330, and the third axis L3 coincides with the central axis of the lens module 400. The first adjustment assembly 500 is connected to the first movable part 320, and the first adjustment assembly 500 is used to adjust the rotation angle of the first movable part 320 around the second axis L2. The first linkage adjustment shaft 700 passes through the fuselage shell 200 and is sealed with the fuselage shell 200, and one end of the first linkage adjustment shaft 700 located in the fuselage shell 200 is transmission-connected to the first adjustment assembly 500. The second adjustment assembly 600 is connected to the second movable part 330, and the second adjustment assembly 600 is used to adjust the rotation angle of the second movable part 330 around the third axis L3. The second linkage adjustment shaft 800 passes through the fuselage shell 200 and is sealed with the fuselage shell 200, and one end of the second linkage adjustment shaft 800 located in the fuselage shell 200 is transmission-connected to the second adjustment assembly 600.

[0029] In the hemispherical camera 10 of the embodiment of the present application, the body shell 200 is connected to the base 100 in a manner that it can rotate around the first axis L1, that is, the body shell 200 can rotate relative to the base 100, so the first axis L1 is the first rotation axis of the hemispherical camera 10. The first movable part 320 of the angle conversion mechanism 300 is connected to the bracket 310 in a manner that it can rotate around the second axis L2, and the bracket 310 is fixed to the body shell 200, thereby enabling the first movable part 320 to rotate relative to the body shell 200, so the second axis L2 is the second rotation axis of the hemispherical camera 10. In addition, the second movable part 330 of the angle conversion mechanism 300 is connected to the first movable part 320 in a manner that it can rotate around the third axis L3, and the lens module 400 is fixed to the second movable part 330, thereby enabling the lens module 400 to rotate relative to the first movable part 320, so the third axis L3 is the third rotation axis of the hemispherical camera 10. By adjusting the rotation angles of the various components around the above three rotation axes, the posture angle of the lens module 400 can be adjusted.

[0030] Specifically, the installer can set the angle around the first rotation axis by rotating the body shell 200. In addition, the installer can rotate the first linkage adjustment shaft 700, and the first linkage adjustment shaft 700 transmits the rotation to the first adjustment component 500, thereby setting the angle around the second rotation axis through the first adjustment component 500. Furthermore, the installer can rotate the second linkage adjustment shaft 800, and the second linkage adjustment shaft 800 transmits the rotation to the second adjustment component 600, thereby setting the angle around the third rotation axis through the second adjustment component 600. Since the first linkage adjustment shaft 700 and the second linkage adjustment shaft 800 are both sealed and connected to the body shell 200, the lens module 400 is always in a sealed state during the process of adjusting the attitude angle of the lens module 400, thereby preventing water vapor in the air from invading the interior of the hemispherical camera.

[0031] In addition, compared with the prior art, the dome camera 10 of the embodiment of the present application can set the angle around the second rotation axis and the angle around the third rotation axis from the outside of the body shell 200. In other words, it is not necessary to disassemble the body shell 200 during the process of adjusting the attitude angle of the lens module 400. This is also conducive to improving the installation efficiency of the dome camera 10, and can also avoid the risk of damaging internal components due to disassembling the body shell 200.

[0032] In some embodiments of the present application, the first movable part 320 includes an outer cylinder 321 and a transmission shaft 322 fixed on the outer wall of the outer cylinder 321, and the first adjustment component 500 is connected to the transmission shaft 322, and the central axis of the transmission shaft 322 coincides with the second axis L2. In this embodiment, the first adjustment component 500 is connected to the transmission shaft 322, so that the transmission shaft 322 can be driven to rotate through the first adjustment component 500, and the transmission shaft 322 drives the outer cylinder 321 to rotate while rotating, thereby realizing the adjustment of the rotation angle of the first movable part 320 relative to the bracket 310.

[0033] In some embodiments of the present application, the second movable part 330 includes an inner cylinder 331 disposed in the outer cylinder 321, at least part of the structure of the lens module 400 is fixed in the inner cavity of the inner cylinder 331, and the second adjustment assembly 600 is connected to the inner cylinder 331. In this embodiment, the second adjustment assembly 600 is connected to the inner cylinder 331, so that the inner cylinder 331 can be driven to rotate by the second adjustment assembly 600, and the inner cylinder 331 drives the lens module 400 to rotate while rotating, thereby achieving the adjustment of the rotation angle of the lens module 400 relative to the first movable part 320.

[0034] Furthermore, the second movable part 330 may also include an inner cylinder rear cover 332 , which is installed at the end of the inner cylinder 331 . The inner cylinder rear cover 332 can protect the portion of the lens module 400 located in the inner cavity of the inner cylinder 331 to a certain extent.

[0035] Furthermore, the central axis of the lens module 400, the central axis of the inner cylinder 331 and the central axis of the outer cylinder 321 are in a coincident relationship. In this way, the adjustment process of the attitude angle of the lens module 400 can be relatively simple, thereby facilitating the adjustment efficiency of the attitude angle of the lens module 400.

[0036] In some embodiments of the present application, Figure 4 , Figure 5 As shown, the first adjustment assembly 500 includes a first gear 510, a second gear 520 and a first adjustment column 530. The first gear 510 is sleeved on the transmission shaft 322, the first gear 510 is used to drive the transmission shaft 322 to rotate, the second gear 520 is meshed with the first gear 510, the first adjustment column 530 is coaxial with the second gear 520 and fixedly connected, and the end of the first adjustment column 530 is provided with a first transmission groove 531 for connecting with the first linkage adjustment shaft 700. Based on the first adjustment assembly 500 in this embodiment, the first transmission groove 531 at the end of the first adjustment column 530 is used to cooperate with the first linkage adjustment shaft 700. When the installer rotates the first linkage adjustment shaft 700, the first linkage adjustment shaft 700 drives the first adjustment column 530 to rotate, and the first adjustment column 530 further drives the transmission shaft 322 to rotate through the second gear 520 and the first gear 510. When the transmission shaft 322 rotates, it drives the outer cylinder 321 to rotate around the central axis of the transmission shaft 322. It can be seen that the first adjustment component 500 in this embodiment can meet the adjustment requirement for the rotation angle of the first movable part 320 .

[0037] Specifically, a pin 3214 is provided on the outer wall of the outer cylinder 321, and the first gear 510 is sleeved on the transmission shaft 322 and is coaxial with the transmission shaft 322. In addition, a positioning hole can be provided on the side of the first gear 510 facing the outer cylinder 321, and the pin 3214 is inserted into the positioning hole. In this way, when the first gear 510 rotates, the transmission shaft 322 coaxial with it can be driven to rotate together.

[0038] Furthermore, if Figure 3 , Figure 4As shown, the bracket 310 includes a bottom plate 311 and a first side plate 312 fixed to the bottom plate 311, the first side plate 312 is arranged perpendicular to the bottom plate 311, a first through hole 3121 and a second through hole 3122 are arranged on the first side plate 312, the transmission shaft 322 is rotatably matched with the first through hole 3121, the first gear 510 and the second gear 520 are both located on the inner side of the first side plate 312, the first adjustment column 530 is passed through the second through hole 3122, a first limiting flange 532 is formed on the first adjustment column 530, and the first limiting flange 532 is arranged on the outer side of the first side plate 312. The inner side of the first side plate 312 refers to the side of the first side plate 312 close to the outer cylinder 321, and the outer side of the first side plate 312 refers to the side of the first side plate 312 away from the outer cylinder 321. The first adjustment assembly 500 further includes a first pressing plate 540, which is connected to the first side plate 312, and the first limiting flange 532 is held between the first pressing plate 540 and the first side plate 312. In this embodiment, the transmission shaft 322 is rotatably matched with the first through hole 3121, thereby realizing the rotatable connection between the outer cylinder 321 and the bracket 310. In addition, the first side plate 312 is arranged perpendicular to the bottom plate 311, so that when the bottom plate 311 is installed perpendicular to the first axis L1, the central axis of the transmission shaft 322 matched with the first through hole 3121 on the first side plate 312 must be perpendicular to the first axis L1, thereby, a perpendicular relationship between the second axis L2 and the first axis L1 can be established.

[0039] In some embodiments of the present application, Figure 4 , Figure 5 As shown, a limiting protrusion 3211 is formed on the outer wall of the outer cylinder 321, and a first stopper 3123 and a second stopper 3124 are provided on the bracket 310 (specifically, the edge of the first side plate 312). The first stopper 3123 and the second stopper 3124 limit the rotation angle range of the outer cylinder 321 relative to the bracket 310 by blocking the limiting protrusion 3211. It can be understood that the positions of the first stopper 3123 and the second stopper 3124 can be set according to actual use needs, that is, by reasonably selecting the positions of the first stopper 3123 and the second stopper 3124, the outer cylinder 321 can be rotated within a preset angle range, for example, within 90 degrees. In this way, it can be prevented that the lens module 400 is pointed to an invalid shooting angle (for example, the angle of the lens module 400 pointing to the base 100) due to the excessive rotation angle of the outer cylinder 321.

[0040] In some embodiments of the present application, a blocking member 3212 is provided at the end of the outer cylinder 321, and a first limiting strip 3311 and a second limiting strip 3312 are provided at the end of the inner cylinder 331, and the blocking member 3212 limits the rotation range of the inner cylinder 331 relative to the outer cylinder 321 by blocking the first limiting strip 3311 and the second limiting strip 3312. It can be understood that the positions of the first limiting strip 3311 and the second limiting strip 3312 can be set according to actual use needs, that is, by reasonably selecting the positions of the first limiting strip 3311 and the second limiting strip 3312, the inner cylinder 331 can be rotated within a preset angle range. In this way, it is possible to avoid excessive torsion damage to the cable connected to the lens module 400 due to excessive rotation angle of the inner cylinder 331.

[0041] In some embodiments of the present application, Figure 4 , Figure 6 As shown, the second adjustment assembly 600 includes a ring gear 610, a third gear 620, a fourth gear 630 and a second adjustment column 640. The ring gear 610 is arranged at one end of the inner cylinder 331, the third gear 620 is meshed with the ring gear 610, the fourth gear 630 is meshed with the third gear 620, the second adjustment column 640 is coaxial with the fourth gear 630 and fixedly connected, and the end of the second adjustment column 640 is provided with a second transmission groove 641 for connecting with the second linkage adjustment shaft 800. Based on the second adjustment assembly 600 in this embodiment, the second transmission groove 641 at the end of the second adjustment column 640 is used to cooperate with the second linkage adjustment shaft 800. When the installer rotates the second linkage adjustment shaft 800, the second linkage adjustment shaft 800 drives the second adjustment column 640 to rotate, and the second adjustment column 640 further drives the ring gear 610 to rotate through the fourth gear 630 and the third gear 620. The ring gear 610 drives the inner cylinder 331 to rotate around its own central axis while rotating. It can be seen that the second adjustment component 600 in this embodiment can meet the adjustment requirement for the rotation angle of the second movable part 330 .

[0042] Further, the third gear 620 may be a double-layer gear including a bevel gear portion 621 and a spur gear portion 622, wherein the bevel gear portion 621 is meshed with the ring gear 610, and the spur gear portion 622 is meshed with the fourth gear 630. In this way, the third gear 620 can be better able to perform transmission. Accordingly, the teeth on the ring gear 610 also use bevel teeth to facilitate matching with the bevel gear portion 621.

The inner side of the second side plate 313 refers to the side of the second side plate 313 close to the outer cylinder 321, and the outer side of the second side plate 313 refers to the side of the second side plate 313 away from the outer cylinder 321. The second adjustment assembly 600 also includes a second pressing plate 650, which is connected to the second side plate 313, and the second limiting flange 642 is retained between the second pressing plate 650 and the second side plate 313. In this embodiment, the central axis of the connecting shaft 3213 and the central axis of the transmission shaft 322 are in a colinear relationship, and at the same time, the connecting shaft 3213 is rotatably matched with the third through hole 3131, so that one side of the outer cylinder 321 is supported on the bracket 310 through the transmission shaft 322, and the other side of the outer cylinder 321 is supported on the bracket 310 through the connecting shaft 3213, thereby improving the connection stability between the outer cylinder 321 and the bracket 310. In addition, the connecting shaft 3213 also provides a mounting base for the third gear 620.

In this embodiment, screwdriver grooves 720 and 820 are respectively provided at the other ends of the first linkage adjustment shaft 700 and the second linkage adjustment shaft 800, so that the installer can use a screwdriver to rotate the first linkage adjustment shaft 700 and / or the second linkage adjustment shaft 800, thereby adjusting the attitude angle of the lens module 400. In addition, at least one sealing ring 1100 is provided between the first linkage adjustment shaft 700 and the inner wall of the placement groove 220, and at least one sealing ring 1100 is provided between the second linkage adjustment shaft 800 and the inner wall of the placement groove 220, so that the first linkage adjustment shaft 700, the second linkage adjustment shaft 800 and the body shell 200 can be sealed and connected, thereby ensuring that water vapor in the external air cannot invade the interior of the body shell 200.

[0045] Further, the first linkage adjustment shaft 700 and the second linkage adjustment shaft 800 are both provided with flange structures 730, 830, and the first linkage adjustment shaft 700 and the second linkage adjustment shaft 800 are respectively sleeved with a pressure ring 1200, an internal thread is provided on the inner wall of the placement groove 220, and an external thread matching the internal thread is provided on the pressure ring, and at least one of the sealing rings 1100 is located between the pressure ring 1200 and the flange structures 730, 830.

In this embodiment, the transparent cover 1000 and the upper cover 1600 are coaxial and fixedly connected, and a mounting angle of 5° to 15° is formed between the central axis of the upper cover 1600 and the central axis of the body shell 200, so that the field of view of one side of the hemispherical camera 10 can be expanded. During the assembly process, the lens module 400 is directed toward the side with a larger field of view, so that the lens module 400 can have a larger effective shooting angle. For example, the rotation angle range of the lens module 400 around the second rotation axis can be made to be greater than 90°.

[0047] In some embodiments of the present application, the hemispherical camera 10 further includes an auxiliary lighting lamp 1300 disposed on the body shell 200 and a reflector 1400 disposed on the auxiliary lighting lamp 1300. Specifically, the auxiliary lighting lamp 1300 can be disposed on the side of the hemispherical camera 10 that faces the same direction as the lens module 400, so as to better provide auxiliary lighting for the hemispherical camera 10. Furthermore, the angle between the central axis L5 of the auxiliary lighting lamp 1300 and the horizontal plane (when the hemispherical camera 10 is installed in the environment) can be 10° to 30°. In this way, it is conducive to making the lighting distance longer. The reflector 1400 is disposed above the light-emitting area of ​​the auxiliary lighting lamp 1300, and the reflector 1400 is used to reflect the lighting light to the near-field area, thereby expanding the lighting range of the auxiliary lighting lamp 1300.

[0048] Furthermore, the reflector 1400 is disposed on the auxiliary lighting lamp 1300 in an angle-adjustable manner, thereby enabling the angle of the reflected light to be adjusted, thereby facilitating expansion of applicable scenarios.

[0049] In addition, when the auxiliary lighting lamp 1300 is working, the body shell 200 is used as a heat dissipation carrier, and the heat of the lamp board is exchanged into the air through the surface of the body shell 200, thereby effectively reducing the temperature of the auxiliary lighting lamp 1300.

[0050] In some embodiments of the present application, some externally adjustable waterproof buttons 1500 may be provided on the surface of the upper cover 1600. These waterproof buttons 1500 may be used for resetting the camera system, adjusting the zoom of the lens module 400, etc., or may also serve as status indicator lights. Figure 2As shown, a mounting opening 110 is formed on the base 100, a part of the body shell 200 extends into the interior of the base 100 through the mounting opening 110, an outer flange 210 is formed at one end of the body shell 200 located inside the base 100, the outer diameter of the outer flange 210 is larger than the diameter of the mounting opening 110, a plurality of holding members 120 arranged near the mounting opening 110 are provided inside the base 100, and the holding members 120 and the base 100 jointly form a clamping effect on the outer flange 210. In this embodiment, a part of the body shell 200 extends into the interior of the base 100 through the mounting opening 110, and the outer diameter of the outer flange 210 at the end of the body shell 200 is larger than the diameter of the mounting opening 110, thereby preventing the body shell 200 from coming off the mounting opening 110, and maintaining a rotatable connection relationship between the body shell 200 and the base 100. In addition, a plurality of holding members 120 are arranged inside the base 100, and the holding members 120 and the base 100 together form a clamping effect on the outer flange 210, thereby increasing the friction between the body shell 200 and the base 100, so that after the installer adjusts the rotation angle of the body shell 200 relative to the base 100, the body shell 200 can be maintained at this angle, which is beneficial to maintain the lens module 400 at a stable posture angle.

[0051] Specifically, the pressing member 120 may be connected to the base 100 via a screw 140 , and thus, by adjusting the screwing depth of the screw 140 on the base 100 , the clamping force of the clamping member 120 on the outer flange 210 may be adjusted.

[0052] In some embodiments of the present application, a locking screw 130 for tightening the body shell 200 is installed on the base 100. After the installer adjusts the rotation angle of the body shell 200 relative to the base 100, the locking screw 130 can be used to tighten the body shell 200, thereby ensuring that the body shell 200 is more stably maintained at the adjusted angle.
