[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0049] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0050] As Figure 1-13As shown, an embodiment of the utility model provides a hemispherical camera, including a shell, a camera body 5, a circuit board assembly and a rotating assembly 6, wherein the circuit board assembly is installed in the shell, and the camera body 5 is installed in the shell for filming; wherein the camera body 5 can be rotated inside the shell by the rotating assembly 6, so as to adjust the camera monitoring angle of the internal lens 51, specifically, the rotating assembly 6 includes a rotating ring 61, a rotating bracket 62 and a card cover 63, wherein the rotating ring 61 is connected to the camera body 5, and the two are connected as a whole and can move together, and the rotating ring 61 is rotatably installed on one end of the rotating bracket 62, so that the rotating ring 61 can rotate based on the rotation axis on the rotating bracket 62, and the other end of the rotating bracket 62 is rotatably installed on the card cover 63, and the card cover 63 is connected in the shell, and the rotating bracket 62 is based on the card cover. 63, and the rotating ring 61 and the rotating bracket 62 can rotate independently, and the rotation of the two does not interfere with each other, and the rotating axis 611 line of the rotating ring 61 is perpendicular to the rotating axis 611 line of the rotating bracket 62, so that the rotation direction of the rotating ring 61 is different from the rotation direction of the rotating bracket 62, so that the camera body 5 connected to the selection rotating ring can rotate independently in two directions respectively. Compared with adjusting the camera monitoring angle of the camera body 5 in a single rotation direction, the camera body 5 rotates in two rotation directions to make a secondary adjustment to the camera monitoring angle. Of course, the adjustments are made in no particular order, so that the camera monitoring angle of the camera body 5 can have more options, and the monitoring angle can be flexibly adjusted to meet daily monitoring needs, and some tricky camera angles can also be met to a certain extent.

[0051] Specifically, in this embodiment, if Figure 5 As shown, the outer wall of the rotating ring 61 is provided with two rotating shafts 611, the rotating shafts 611 are perpendicular to the outer wall of the rotating ring 61, and the two rotating shafts 611 are symmetrically arranged about the central axis of the rotating ring 61. Correspondingly, one end of the rotating bracket 62 is provided with two connecting parts 621, and the connecting parts 621 are provided with rotating holes 622. The two rotating shafts 611 are correspondingly inserted into the rotating holes 622 and can rotate on the rotating holes 622, so that the rotating ring can rotate around the central axis of the rotating hole 622 through the two rotating shafts 611 on the outer wall, thereby driving the corresponding The camera body 5 can realize a primary adjustment of the camera monitoring angle; after the rotating ring 61 is adjusted, the rotating ring 61 and the rotating bracket 62 are connected into a whole through the fixing part, so that when the rotating bracket 62 rotates, it can indirectly drive the camera body 5 to perform a secondary adjustment of the camera monitoring angle. Specifically, the fixing part can be a screw, and a threaded hole is provided at the end of the rotating shaft 611. It is only necessary to connect the screw to the threaded hole, and the screw abuts the connecting part 621 away from the side wall of the rotating ring 61 to realize the overall connection between the rotating ring 61 and the rotating bracket 62.

[0052] Specifically, a plurality of first bumps 612 are circumferentially and uniformly arranged on the outer sidewall of the rotating shaft 611. The first bumps 612 are in clearance fit with the rotating holes 622. After the rotating shaft 611 is inserted into the rotating holes 622, the rotating shaft 611 has a certain contact friction force between the first bumps 612 and the sidewalls of the rotating holes 622. When the rotating ring 61 rotates, the effect of stopping immediately after rotation can be achieved through the first bumps 612, avoiding the situation that after the rotation angle, manual stopping and manual holding are required, otherwise the angle of the rotating ring 61 is likely to change under the influence of gravity or other factors. Of course, it can be known that although the rotating ring 61 can stop immediately after rotation through the first bumps 612, in order to ensure the accuracy of the rotation angle of the rotating ring 61, after the rotating ring 61 rotates to completion, manual holding is still required, and then it is fixed through the fixing member.

[0053] Specifically, as Figure 6 shown, a plurality of second bumps 623 are arranged on the sidewall of the connecting portion 621 close to the rotating ring 61. The plurality of second bumps 623 are circumferentially and uniformly distributed along the axis of the rotating hole 622. When the rotating bracket 62 and the rotating ring 61 are connected into a whole through the fixing member, the second bumps 623 are in contact with the outer sidewall of the rotating ring 61, ensuring the friction force between the connecting portion 621 and the outer sidewall of the rotating ring 61, and avoiding relative rotation between the rotating ring 61 and the connecting portion 621 under external factors after fixation, resulting in a change in the camera monitoring angle of the camera body 5.

[0054] Specifically, in this embodiment, as Figure 7 shown, an installation hole 631 is formed in the middle of the cover 63. The other end of the rotating bracket 62 is arranged in an annular structure and is rotatably installed on the installation hole 631. Of course, the outer diameter of the end of the rotating bracket is designed to be adapted to the aperture of the installation hole 631, so that the rotating bracket 62 can rotate circumferentially around the axis of the installation hole 631, so that the rotating bracket can drive the camera body 5 to perform secondary adjustment of the camera monitoring angle; specifically, in order to limit the rotating bracket 62, a first annular boss 624 is arranged on the outer sidewall of the other end of the rotating bracket 62, and a second annular boss 632 is arranged on the inner sidewall of the installation hole 631, so that the sidewall of the first annular boss 624 close to the rotating ring 61 is in contact with the sidewall of the second annular boss 632 far from the rotating ring 61. Moreover, the cover 63 is connected to the inner sidewall of the housing, so that the first annular boss 624 is limited between the second annular boss 632, the sidewall of the installation hole 631 and the inner sidewall of the housing, completing the limitation of the other end of the rotating bracket 62. Of course, after the cover 63 is connected to the inner sidewall of the housing, the second annular boss 632 presses the first annular boss 624. Through the design and adjustment of the existing technology, the end of the rotating bracket 62 can stop immediately after rotation on the installation hole 631, which will not be elaborated here.

[0055] Specifically, the housing includes a spherical cover 1, a spherical cover retaining ring 2, an upper cover 3, and a base 4. The spherical cover 1, the upper cover 3, and the base 4 are connected in sequence to form an inner cavity for installing the camera body 5, the circuit board assembly, and the rotating assembly 6. Specifically, both ends of the upper cover 3 are open, one end has a larger opening and the other end has a smaller opening, and it transitions from the end with the larger opening to the end with the smaller opening in an arc shape. One end of the spherical cover 1 is sealed and the other end is open. The sealed end of the spherical cover 1 is inserted into the upper cover 3 from the larger opening and extends out from the smaller opening. The open end of the spherical cover 1 is located inside the smaller end of the upper cover 3, and the two are connected through the spherical cover retaining ring 2. The larger end of the upper cover 3 is connected to the base 4, and an upper cover sealing ring 8 is provided at the connection between the two. The cover 63 can be connected to the inner bottom side wall of the base 4 through bolts. Specifically, the upper cover 3 and the base 4 are made of all-aluminum alloy material, which has better heat dissipation performance. Specifically, during the entire use of the camera, when it is necessary to readjust the camera's shooting and monitoring angle again, only the upper cover 3 needs to be removed so that the camera body 5, the rotating ring 61, and the rotating bracket 62 are exposed. Then, the rotating ring 61 and the rotating bracket 62 can be rotated. After the camera's shooting and monitoring angle is adjusted completely, the rotating ring 61 is fixed completely, and then the upper cover 3 is installed. Specifically, the circuit board assembly includes a main control board 9 and a POE board 10. The main control board 9 and the POE board 10 are both installed between the base 4 and the cover 63. A memory card and a reset button are also provided between them. The cover has a silicone sealing ring to ensure complete airtightness. Of course, necessary components such as a speaker are also installed inside the entire housing, which are not listed one by one here.

[0056] Specifically, as Figure 9-13 shown, the housing further includes a spherical cover sealing ring 7, which is used to seal the connection between the spherical cover 1 and the upper cover 3 to prevent water vapor from generating inside the spherical cover 1 and causing the camera body 5 to have unclear shooting through the spherical cover 1. Specifically, a third annular boss 11 is provided on the outer side wall of the end (open end) of the spherical cover 1 close to the upper cover 3, a fourth annular boss 31 is provided on the inner side wall of the end (smaller opening end) of the upper cover 3 close to the spherical cover 1, and a fifth annular boss 32 is provided on the inner side wall of the fourth annular boss 31. Specifically, as Figure 11As shown, the fourth annular boss 31 extends radially. One end of the fifth annular boss 32 is on the inner sidewall of the fourth annular boss 31, and the other end extends in a direction away from the small-mouth end of the upper cover 3. When the open end of the spherical cover 1 is installed at the small-mouth end of the upper cover 3, the third annular boss 11 is located inside the small-mouth end of the upper cover 3. The fifth annular boss 32, the fourth annular boss 31, the third annular boss 11, and the outer sidewall of the spherical cover 1 form an annular installation cavity. The cross-sectional area of the annular installation cavity is Z-shaped. The spherical cover sealing ring 7 is installed in the annular installation cavity. Specifically, the spherical cover sealing ring 7 is of an L-shaped structure and is installed in the annular installation cavity with an L-shaped cross-section formed by the fourth annular boss 31, the third annular boss 11, and the outer sidewall of the spherical cover 1. Thus, the spherical cover sealing ring 7 plays a sealing role, and the sealing path is long and the sealing effect is good. The Z-shaped annular installation cavity plays another sealing role, thereby realizing a double-sealing effect and making the sealing effect at the connection between the open end of the spherical cover 1 and the small-mouth end of the upper cover 3 better. Of course, after the open end of the spherical cover 1 is installed inside the small-mouth end of the upper cover 3, the sidewall of the spherical cover pressing ring 2 abuts against the third annular boss 11. In this embodiment, there are a plurality of connecting posts with threaded holes on the sidewall of the fifth annular boss 32. There are connecting holes on the spherical cover pressing ring 2. The spherical cover pressing ring 2 is connected to the fifth annular boss 32 by a plurality of screws, so that the spherical cover pressing ring 2 is connected to the upper cover 3, and the third annular boss 11 at the open end of the spherical cover 1 is limited between the spherical cover pressing ring 2 and the fourth annular boss 31, realizing the fixation of the spherical cover 1.

[0057] Specifically, there is at least one pre-tightening protrusion 33 on the inner sidewall of the fifth annular boss 32 facing the central axis of the upper cover 3. In this embodiment, there are a plurality of pre-tightening protrusions 33, which are circumferentially distributed on the inner sidewall of the fifth annular boss 32. After the spherical cover 1 is connected to the upper cover 3, that is, when the open end of the spherical cover 1 is located at the small-mouth end of the upper cover 3, the pre-tightening protrusion 33 abuts against the outer sidewall of the third annular boss 11. Thus, when the third annular boss 11 is not connected through the spherical cover pressing ring 2, it can be stably located at the small-mouth end of the upper cover 3, facilitating the connection of the spherical cover pressing ring 2 and further making the connection between the spherical cover 1 and the upper cover 3 more stable.

[0058] Specifically, as Figure 1As shown in the figure, the camera body 5 includes a lens 51, a lamp board 52, a lamp cover 53, a zoom aperture stop 54, an image sensor bracket 55 and an image sensor board 56. The lens sleeve is sleeved on the outer peripheral side of the lens 51, and the imaging end of the lens 51 passes through the installed zoom aperture stop 54 at the opening of the lamp cover 53 and faces the dome 1. The connecting end of the lens 51 is connected to the image sensor board 56. The image sensor bracket 55 is sleeved on the outer side of the connecting end of the lens 51. One end of the image sensor bracket 55 is connected to one end of the lamp cover 53 away from the zoom aperture stop 54, and the other end is connected to the image sensor board 56. The rotating ring 61 is sleeved on the outer side of the image sensor bracket 55, and the rotating ring 61 abuts against the lamp cover 53. Thus, the rotating ring 61 and the lamp cover 53 form a support housing for the lens 51 to carry the internal lens 51 to rotate. Specifically, in this embodiment, the lens 51 can be used for zooming to meet the usage requirements.

[0059] Specifically, a plurality of through holes are provided on the side wall of the rotating ring 61 and are evenly distributed circumferentially. An L-shaped limiting block 613 is connected to the side wall of the through hole. The horizontal part of the L-shaped limiting block 613 is located inside the rotating ring 61, thus forming an elastic piece. Correspondingly, a plurality of limiting protrusions 551 are provided on the outer side wall of the image sensor bracket 55. The plurality of limiting protrusions 551 cooperate with the horizontal parts of the plurality of L-shaped limiting blocks 613 to form a clamping connection. At this time, the side wall of the horizontal part of the L-shaped limiting block 613 away from the upper cover 3 abuts against the side wall of the limiting protrusion 551 close to the upper cover 3, and the side wall of the end of the rotating ring 61 close to the upper cover 3 abuts against the side wall of the end of the upper cover 3, so that the rotating ring 61 is limited. Thus, the rotating ring 61 is stably connected to the outer peripheral side of the image sensor bracket 55 and is connected to the lamp cover 53 as a whole and can move together.

[0060] The lamp board 52 is installed on the threaded hole on the inner side wall of the lamp cover 53 through bolts, and a light hole is provided on the side wall of the lamp cover 53 away from the image sensor board 56, which is convenient for the lights on the lamp board 52 to shine out. Specifically, the lamp board 52 is provided with red and blue warning lights, infrared night vision and white lights. Among them, the red and blue warning lights (actually a combination of a red light emitter and a blue light emitter) can emit warnings in time when abnormal situations occur, and the infrared night vision and white light filling functions ensure that the camera can obtain clear images under different lighting conditions.

[0061] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
