[0078] In the prior art, for the adjustment of the shooting angle of a camera device such as a monitoring camera, one solution is that the camera device itself is provided with an adjustment structure of the camera, at which time the camera device can be directly fixed on a roof or a horizontal rod. However, the adjustment structure of this solution is integrated on the camera device, and has poor universality. Another solution is to install the camera device on a support, and adjust the shooting angle of the camera device through the support, for example Figure 1 , Figure 2 , Figure 1 , and Figure 2 show two existing support structures, in which Figure 1 the support in Figure 2 is rotated through an arc-shaped sliding groove, and the butt joint lug of the support in is rotated through screw rotation connection. However, both of the above supports need to be manually adjusted, and do not have a remote electric adjustment function, which is inconvenient for use.

[0084] It should be understood that the first driving mechanism and the second driving mechanism drive the support body and the rotation shaft to rotate, respectively, for example, through a driving motor and a transmission device, that is, the electric support of the embodiment can be remotely and electrically controlled, so that the shooting angle of the camera installed thereon is adjusted, and manual adjustment is saved, the efficiency is higher, and the use is convenient.

[0088] Regarding the rotation connection between the support body 20 and the base unit 10, in one possible implementation, the first end of the support body 20 in the first direction X is rotationally connected to the base unit 10 through a rotary bearing 50.

[0089] That is, referring to Figure 5 andFigure 8 The bottom end of the support body can be rotatably connected to the base unit through an adapter bearing.

Then, the bearing outer ring of the adapter bearing is fixedly connected to the inner wall of the mounting wall, and the bearing inner ring of the adapter bearing is fixedly connected to the outer wall of the mounting table, so that the bearing plate and the base unit are rotatably connected, that is, the support body and the base unit are rotatably connected.

[0092] In this embodiment, the adapter bearing is used to rotatably connect the support body and the base unit, which is simple in structure. In combination with Figure 5 and Figure 8 The two ends of the adapter bearing along the first direction can also be pressed by a first bearing pressing plate 53 and a second bearing pressing plate 54 respectively, thereby improving the rotation reliability.

[0093] Regarding the above-mentioned base unit 10 for being fixed to the mounting object 200, in one possible implementation, the electric support further comprises an adapter disc 60, and the fourth end face of the base unit 10 away from the bearing plate 21 is used to be fixed to the adapter disc 60, and the adapter disc 60 is used to be fixed to the mounting object 200.

[0094] That is, first, please refer to Figure 3 and Figure 5 The adapter disc is installed on the fourth end face of the base unit away from the support body, and then the adapter disc is fixed to the mounting object, so that the adapter disc is used for adapter, thereby improving the versatility of the electric support.

[0095] Specifically, please refer to Figures 9 to 12The adapter plate can be installed on different installation objects. For example Figure 10 The adapter plate is shown installed on an installation wall, which is located on a wall or the like; or, as shown in Figure 11 , Figure 12 , the adapter plate can be installed on a columnar crossbar through a hoop support and a hoop; or, as shown in Figure 9 , the adapter plate can be directly installed on a plate-shaped crossbar.

[0096] In the specific installation, please refer to Figure 12 , first, fix the camera device on the bearing platform, and fix the adapter plate on the installation object; then, fix the base unit on the adapter plate through the screw 80 or the like.

[0098] On the basis of the above-mentioned rotational connection between the bearing plate and the base unit, the outer wall of the installation wall is further transmissionally connected with the first driving motor fixed on the bearing plate, so that the first driving motor drives the bearing plate to rotate relative to the base unit.

[0099] Specifically, please refer to Figure 5 and Figure 6 , the first driving motor is fixed on the bearing plate, and a first output shaft of the first driving motor is arranged along the first direction, and the first output shaft is sleeved with a first transmission gear; then, refer to Figure 6 and Figure 7 , the outer wall of the installation wall is provided with a transmission gear ring, and the first driving motor is arranged beside the installation wall, and the first transmission gear is engagedly connected with the transmission gear ring; in combination with the above-mentioned rotational connection between the bearing plate and the base unit through the adapter bearing, in this way, under the rotation of the first output shaft, through the transmission of the first transmission gear and the transmission gear ring, the first driving motor can drive the bearing plate to rotate relative to the base unit.

[0100] That is to say, by means of the above-mentioned installation wall for rotational connection, the first driving motor is transmissionally connected beside the installation wall in this embodiment, so that the first driving motor can drive the bearing plate to rotate relative to the base unit, and the structure is compact.

[0105] Of course, the limited rotation angle or rotation arc can be determined according to actual needs, for example, the rotation angle is 180 degrees, that is, the bearing plate can rotate 180 degrees relative to the base unit with the first direction as the rotation axis direction, so for the camera device, the horizontal adjustment range of the shooting angle is 180 degrees.

[0106] Regarding the above-mentioned arrangement of the rotation shaft 40, in one possible implementation, the support body 20 further includes a support shell 22 which is fixedly connected to the bearing plate 21 and rotates with the bearing plate 21 relative to the base unit 10; wherein the end of the support shell 22 away from the bearing plate 21 is penetrated by the rotation shaft 40 along the second direction Y.

[0110] In this embodiment, the first transmission shaft is located inside the bracket shell and extends along the second direction, then, the two ends of the first transmission shaft are respectively fixedly installed with the rotating shaft sleeves; that is, the first transmission shaft rotates to drive the rotating shaft sleeves at both ends to rotate; and the two ends of the rotating shaft sleeves protruding from the two ends of the bracket shell are respectively fixedly connected with a pair of connecting lugs of the bearing unit, and then the first transmission shaft drives the bearing unit to rotate.

[0111] Specifically, please refer to Figure 5 and Figure 14 , the outer end of the rotating shaft sleeve is provided with a profiling plate, and the inner wall of the connecting lug is provided with a profiling groove, so that the rotating shaft sleeve can transmit the rotation of the first transmission shaft to the bearing unit through the engagement of the profiling groove and the profiling plate; in addition, the profiling groove and the profiling plate also have the effect of preventing mistakes, preventing the installation from being reversed.

[0112] More specifically, please refer to Figure 14 , the rotating shaft sleeve is fixed at the end of the first transmission shaft through a screw along the second direction, then the connecting lug is fixed at the end of the rotating shaft sleeve through a screw along the second direction; in combination with the profiled engagement connection between the connecting lug and the rotating shaft sleeve, the reliability of the connection is ensured.

[0113] In another embodiment, the rotating shaft 40 further comprises a pair of torsion springs 44, the pair of torsion springs 44 being respectively installed corresponding to the pair of rotating shaft sleeves 42; wherein, the first torsion arm of the torsion spring 44 is fixed to the rotating shaft sleeve 42 and rotates with the rotating shaft sleeve 42, and the second torsion arm of the torsion spring 44 abuts against the bracket shell 22.

[0114] Please refer to Figure 15 , that is, under the driving of the first transmission shaft, the rotating shaft sleeve rotates relative to the bracket shell; then, in this embodiment, a torsion spring is installed between the rotating shaft sleeve and the bracket shell, one end of the torsion spring is fixed to the rotating shaft sleeve and rotates with the rotating shaft sleeve, and the other end of the torsion spring abuts against the bracket shell; it should be understood that in this way, the sharp shaking of the shooting picture of the camera device can be prevented, and the smoothness of the shooting picture during the pitch adjustment of the camera device is ensured.

[0115] Please refer to Figure 16and Figure 17 , Figure 16 and Figure 17 This embodiment illustrates the change in the center of gravity of the camera device during pitch adjustment when a torsion spring is installed. It can be seen that, from... Figures 16 to 17 When adjusting the pitch angle clockwise, the presence of the torsion spring applies a force to the rotating sleeve and the first transmission shaft, so that the center of gravity of the camera device always stays on the same side of the vertical line, and there is no situation where the center of gravity jumps from one side to the other side, thus eliminating the switching of the center of gravity between the two sides and ensuring the smoothness of the shooting image during the pitch adjustment.

[0116] It should be understood that, without the torsion spring installed, when adjusting the pitch angle clockwise, the center of gravity of the camera device will shift from one side of the vertical line. Figure 16 (Left side) Jump to the other side ( Figure 17 (The right side of the image), and then taking into account the tolerances of the transmission connection, etc., it is precisely because the center of gravity shifts from one side to the other that the image will shake violently; however, this embodiment can eliminate the above-mentioned violent shaking and improve the shock resistance by setting a torsion spring.

[0117] In another embodiment, a sealing ring 45 is provided between the rotating bushing 42 and the bracket housing 22, and a pair of decorative plates 46 are respectively installed with a pair of rotating bushings 42, the decorative plates 46 being used to press the sealing ring 45.

[0118] In this embodiment, see Figure 5 To ensure waterproofing between the rotating bushing and the bracket housing, a sealing ring is installed between them. Then, the waterproofing effect is improved by pressing the decorative panel together.

[0119] Regarding the aforementioned second drive mechanism, in one possible embodiment, the second drive mechanism includes a second drive motor 241, a second output shaft 242 of the second drive motor 241 extending along a third direction Z, the second output shaft 242 being fixedly connected to a second transmission shaft 243 arranged along the third direction Z, the second transmission shaft 243 being provided with helical teeth 244, the third direction Z being perpendicular to both the first direction X and the second direction Y; the second drive mechanism also includes a second transmission gear 245, the second transmission gear 245 being arranged circumferentially along the first transmission shaft 41, the second transmission gear 245 being meshed with the helical teeth 244 so that the second drive motor 241 drives the first transmission shaft 41 to rotate.

[0120] In other words, the second drive mechanism drives the rotation of the first drive shaft, and then the first drive shaft drives the bearing unit to rotate through the rotating bushings at both ends.

[0121] Among them, see Figure 18The second driving mechanism comprises a second driving motor, a second output shaft of the second driving motor extends in the third direction, and the second output shaft is fixedly connected with a second transmission shaft arranged in the third direction; wherein the fixed connection between the second output shaft and the second transmission shaft can be realized by means of limiting insertion, that is, for example, referring to Figure 18 and Figure 19 The second output shaft is, for example, flat, and then the second transmission shaft is provided with a flat groove for the insertion of the flat second output shaft.

[0122] In addition, continuing to refer to Figure 18 The second transmission shaft is provided with a helical tooth, and the first transmission shaft is provided with a second transmission gear in the circumferential direction, and it should be understood that the rotation of the third direction can be transmitted to the rotation of the second direction through the transmission connection of the helical tooth and the second transmission gear, that is, the second output shaft in the third direction drives the second transmission shaft in the same direction to rotate, and then the rotation is transmitted to the first transmission shaft in the vertical direction, so as to realize the rotation of the first transmission shaft driven by the second driving motor.

[0123] In an embodiment, it should be understood that the first transmission shaft 41 comprises a helical gear shaft or a worm shaft, and the second transmission shaft 243 comprises a worm shaft, that is, the first transmission shaft and the second transmission shaft can be in worm transmission connection or in helical gear worm transmission connection.

[0124] In addition, it can be understood that the helical gear worm transmission connection or the worm transmission connection also has a locking function. That is, the second transmission shaft can drive the first transmission shaft to rotate, however, in reverse, the first transmission shaft cannot drive the second transmission shaft to rotate, thereby facilitating the maintenance of the posture of the camera device, without the need to always power the second driving motor to maintain the posture of the camera device, and compared with ordinary gear transmission, the worm transmission or the helical gear worm transmission has better strength, which is beneficial to prevent violent operation of the installer during installation, thereby preventing damage to the transmission connection.

[0130] That is, the embodiment can limit the pitch angle of the camera by limiting the rotation of the first transmission shaft relative to the gear box.

[0131] Specifically, referring to Figure 20 , the two ends of the first transmission shaft are flat, and then the gear box is provided with a limiting groove on the opposite sides, so that the limiting groove can limit the rotation angle of the first transmission shaft with flat ends relative to the gear box; considering that on the one hand the first transmission shaft is fixedly connected with the bearing unit, and on the other hand the gear box is fixedly connected inside the support body, the pitch angle of the bearing unit relative to the support body can be limited, for example, the rotation of the first transmission shaft is limited to 15 degrees left and right, and the side pitch angle is limited to 15 degrees up and down.

[0134] In an embodiment, the control board 70 is also electrically connected with the camera 100 through a cable 71, and the support shell 22 is provided with a cable hole 221 for the cable 71 to pass through.

[0135] Specifically, referring back to Figure 4The cable hole of the embodiment is located on the support shell, so that the cable of the embodiment can rotate with the support shell and is not easy to be pulled.
