Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera, in particular to a spherical camera with independent rotation and dust removal function of the ball cover. BACKGROUND

[0002] With the rapid development of monitoring technology, the application of spherical camera is more and more widely used. Compared with general camera, the spherical camera has the advantages of wide field of view and good monitoring effect. The main core component of the spherical camera is the camera, which is used to collect pictures and transmit real-time signals to the monitoring center. The conventional spherical camera usually installs the camera in a transparent protective cover to ensure the safe and stable operation.

[0003] The spherical camera is usually installed in an outdoor environment to cover the entire production area and realize real-time monitoring. Due to the harsh outdoor environment, the surface of the protective cover is easily covered with dust or foreign matter after a long time of use, which causes the camera monitoring picture to be unclear and affects the monitoring effect. Therefore, the protective cover needs to be cleaned so that the camera can be used normally. The traditional cleaning method is to use a special camera protective cover cleaning device to wipe and clean the protective cover manually. However, the camera is usually installed at a high place, so manual cleaning is not only time-consuming and labor-intensive but also has safety hazards.

[0004] At present, there are two kinds of spherical cameras with self-cleaning function on the market. One is to use a fixed protective cover, and a wiper is arranged on the surface of the protective cover. The wiper is controlled by a micro motor to make a 180-degree reciprocating motion along the surface of the spherical protective cover, thereby achieving the cleaning effect. The other is to use a fixed wiper, and the spherical protective cover and the camera core inside are driven to rotate synchronously by a micro motor, thereby achieving the effect of dust removal on the surface of the protective cover. Although these two kinds of cameras can replace manual cleaning of the protective cover, the wiper of these two kinds of cameras will affect the smoothness of the camera working inside the protective cover during the cleaning process of the protective cover, block the monitoring picture, and cause the picture to be lost. SUMMARY

[0005] In view of the deficiencies in the prior art, the present application aims to provide a spherical camera with independent rotation and dust removal function of the ball cover, which can realize independent rotation of the ball cover and the core assembly inside, and will not cause the monitoring picture to be lost during the rotation and dust removal of the ball cover, thereby improving the smoothness of the monitoring picture and the stability of the camera working, and effectively solving the technical problem that the monitoring picture is lost due to the rotation of the ball cover and the camera core together during the cleaning process of the existing spherical camera.

The output shaft of the driving motor 32 penetrates through the movement fixing plate 11 and is fixedly connected with the driving gear 33 located below the movement fixing plate 11, and the output shaft of the driving motor 32 and the driving gear 33 can realize synchronous linkage, and the driving gear 33 is meshingly connected with the rotating seat 31.

[0044] With reference to Figure 2 and Figure 4 , the rotating seat 31 comprises a gear portion 311 located below the movement fixing plate 11 and a connecting portion 312 connected with the gear portion 311, the outer diameter of the gear portion 311 is larger than that of the connecting portion 312, and the inner diameter of the connecting portion 312 is smaller than that of the gear portion 311. The rotating seat 31 is sleeved in the mounting portion 12 through the step portion formed between the gear portion 311 and the connecting portion 312. The outer side surface of the gear portion 312 is annularly provided with a gear and is meshingly connected with the driving gear 33, and the connecting portion 312 is sleeved in the inner ring of the mounting portion 12 and fixedly connected with the ball cover 2. Under the driving of the driving motor 32, the driving gear 33 is meshingly connected with the gear portion 311 to drive the rotating seat 31 and the ball cover 2 to synchronously rotate.

[0045] With reference to Figure 2 and Figure 3 , the movement assembly 4 comprises a camera assembly 41 and a camera connecting seat 42, and the camera assembly 41 is fixed below the camera connecting seat 42. The lower surface of the movement fixing plate 11 is provided with an annular movement connecting seat 112, a through hole 113 is formed in the central position of the movement fixing plate 11 and penetrates through the movement connecting seat 112, and the upper portion of the camera connecting seat 42 is sleeved outside the movement connecting seat 112 and can rotate around the axis thereof. Figure 2 and Figure 4 , a ring of movement gears 421 is annularly provided on the outer side surface of the camera connecting seat 42, and the movement gears 421 are meshingly connected with the movement transmission mechanism 5. The camera connecting seat 42 and the movement connecting seat 112 are further connected with a bearing member 43 to ensure the smoothness of the rotating process and reduce the abrasion. The camera connecting seat 42 is clamped below the movement fixing plate 11 through the bearing member 43, and at the same time, the camera connecting seat 42 is pressed on the upper opening end of the ball cover 2, so as to limit the position of the camera connecting seat 42 in the vertical direction to avoid the vertical displacement of the camera connecting seat 42 in the rotating process, and ensure the stability of the rotating process of the camera assembly 41.

[0046] With reference to Figure 2 , Figure 3 and Figure 6The core transmission mechanism 5 comprises a core motor 51 and a worm gear transmission assembly 52 connected with the output end of the core motor 51. The core motor 51 is fixedly connected with the core fixed plate 11 through a motor fixing seat 53, and the worm gear transmission assembly 52 is in meshing engagement with the core gear 43. Under the driving of the core motor 51, the camera connecting seat 42 and the camera assembly 41 can be driven to synchronously rotate around the central axis through the worm gear transmission assembly 52. Meanwhile, the core motor 51 can realize forward rotation and reverse rotation, and the camera can be quickly reciprocatingly rotated in the horizontal direction, so as to adjust the camera and ensure that the camera can achieve 360-degree monitoring coverage and the monitoring reliability of the camera.

[0047] With reference to Figure 2 and Figure 5 The lower portion of the core fixed plate 11 is further provided with a limiting mechanism 7, which comprises a limiting switch 71 and a limiting baffle 72. The limiting switch 71 and the limiting baffle 72 are fixedly connected with the core fixed plate 11. The outer edge of the camera connecting seat 42 is provided with a sensing block 422 which is in sensing cooperation with the limiting switch 71, and a limiting block 423 which can abut against the limiting baffle 72. When the camera connecting seat 42 is driven to rotate by the core motor 51, the sensing block 422 passes through the limiting switch 71 above, and the sensor in the limiting switch 71 generates an electric signal to control the core motor 51 to stop forward rotation. Meanwhile, the limiting block 423 on the other side abuts against the limiting baffle 72 above to form a blocking limit, so as to limit the rotating angle of the camera assembly. Then, the core motor 51 is reversely rotated to control the camera connecting seat 42 to reversely rotate. When the sensing block 422 passes through the limiting switch 71 again and the limiting block 423 abuts against the other side of the limiting baffle 72, the camera completes a period of reciprocating rotation. The above reciprocating rotation process is repeated to realize uninterrupted 24-hour and 360-degree real-time monitoring.

[0048] With reference to Figure 1 and Figure 3 The upper end of the shell 1 is provided with an upper cover 8. The upper cover 8 and the shell 1 are fixedly connected through screws. A sealing gasket can be further arranged between the upper cover 8 and the shell 1 to improve the sealing property. When the spherical camera is installed and used, the upper cover 8 is fixedly connected with the wall surface or the installation platform.

[0049] With reference to Figure 2 and Figure 4In other possible embodiments of the present application, an annular opening groove 121 is also formed on the inner ring side surface of the mounting portion 12, the opening direction is radially inward, and an annular sealing ring 123 is embedded in the opening groove 121 to ensure the sealing when the rotating seat 31 is connected with the shell 1, improve the waterproof effect, and avoid the water vapor and moisture from entering the inside of the shell to affect the operation of the electronic device. The sealing ring 123 and the opening groove 121 and the connecting portion 312 are all in interference fit with each other. The cross-sectional shape of the side of the sealing ring 123 close to the connecting portion 312 is triangular, and abuts against the outer side surface of the connecting portion 312, so as to minimize the friction between the rotating seat 31 and the shell 1 when the rotating seat 31 rotates inside the mounting portion 12 under the premise of ensuring the connection sealing.

[0050] With reference to Figure 2 , Figure 4 and Figure 7 In other possible embodiments of the present application, a glue filling groove 317 opening upward is formed on the part of the upper surface of the connecting portion 312 abutting against the ball cover 2, and the glue filling groove 317 is filled with sealing glue when the connecting portion 312 is connected with the ball cover 2, so as to fix the ball cover 2 and the rotating seat 31, and make them rotate synchronously.

Figure 5The lower surface of the machine core fixing plate 11 is annularly provided with an annular baffle 111 coaxial with the rotating seat 31. The side surface of the limiting steel ball 316 extends out of the clamping groove 315 and abuts against the lower surface of the machine core fixing plate 11 and the outer side surface of the annular baffle 111 to form point contact, so as to limit the relative position of the rotating seat 31 in the horizontal direction and the vertical direction, avoid vertical displacement and horizontal radial displacement of the rotating seat 31 in the rotating process, and at the same time, the contact area between the rotating seat 31 and the annular baffle 111 can be reduced as much as possible, and the frictional resistance of the rotating seat 31 in the rotating process is reduced.

[0053] With reference to Figure 1 And Figure 3 In other possible embodiments of the present application, the side surface shape of the wiper rubber strip 62 attached to the spherical cover 2 is a circular arc shape, and a 1 / 4 arc structure can be selected. The wiper rubber strip 62 is attached to the surface of the spherical cover 2 along the weft direction of the spherical cover 2, and the wiper rubber strip 62 is fixed in the interior of the wiper seat 61 through the side surface cover gasket installation plate 63. The wiper rubber strip 62 is made of an elastic material, such as rubber or silicone material, and nitrile rubber is preferably selected, which has a long service life and does not damage the surface finish of the spherical cover 2.

[0054] With reference to Figure 9 In the spherical camera of the present application, at least three groups of infrared lamp plates 9 and one group of white light lamp plates 10 are further installed on the shell 1, so that the camera can capture clear images in a dark environment. The infrared lamp plates 9 and the white light lamp plates 10 are arranged on the lower part of the shell 1 and annularly arranged around the spherical cover 2. Figure 2 And Figure 3 The inner cavity of the shell 1 of the present application is further provided with a pressing plate 14, which is located above the machine core fixing plate 11 and fixedly connected thereto, for pressing and covering the cables in the interior and protecting the machine core motor 51. The side surface of the shell 1 is further provided with a cable penetrating interface 15 for penetrating the internal cables to connect the external power supply. Figure 5 The machine core fixing plate 11 of the present application is provided with a PCB circuit board 44 (only a schematic diagram is shown in the figure), and the electric wires (not shown in the figure) of the camera assembly 41 are connected to the PCB circuit board 44 through the wire penetrating hole 113, the PCB circuit board 44 is electrically connected to the driving motor 32, the machine core motor 51, the limiting switch 71, the infrared lamp plate 9 and the white light lamp plate 10, and the external power supply is connected through the wire penetrating interface 15.

[0055] The shell 1 and the upper cover 8 of the present application are both made of metal materials. The material of the shell 1 can be zinc alloy, and the materials of the upper cover 8 and the machine core fixing plate 11 can be 304 stainless steel.

[0056] In this invention, the installation position and number of limit baffles 72 can be set according to the actual monitoring range. One or two limit baffles 72 can be installed. For example, the limit baffle 72 can be installed on the same side of the circumference corresponding to the position of the wiper mount 61. When the camera connector 42 rotates and the sensing block 422 passes through the upper limit switch 71, the limit block 423 abuts against the side of the limit baffle 72. At this time, the lens on the camera assembly 41 that captures the image rotates exactly one revolution. After rotating one revolution, the limit block 423 abuts against the opposite side of the limit baffle 72, thereby preventing the wiper blade 62 from obstructing the image and causing image loss. The lens on the camera assembly 41 that captures the image is tilted within the area enclosed between the wiper mount and the housing, ensuring the maximum range of the captured image.

[0057] The present invention can adjust the time interval of the rotating dust removal of the ball cover 2 according to the dust removal requirements of the usage environment. The drive motor 32 can drive the ball cover 2 to rotate continuously, so that the wiper blade 62 can remove the dust covering the surface of the ball cover 2 in real time. Alternatively, by adjusting the control parameters, the drive motor 32 can automatically start at a certain time interval to drive the ball cover 2 to rotate for self-cleaning.

[0058] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the invention to these descriptions. Therefore, any technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
