Description

Technical Field

[0001] This utility model relates to the field of image sensing technology, and in particular to an image sensing device. Background Technology

[0002] An image sensing device is a device that converts optical images into electrical signals. It utilizes the photo-to-electrical conversion function of photoelectric devices to convert light signals on a photosensitive surface into electrical signals—"images"—that are proportionally related to the light signals. The key component of this device is the image sensor; common image sensor types include charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) sensors. Image sensing devices capture light and convert it into electrical signals, thereby enabling image capture, transmission, and processing.

[0003] Image sensors have a wide range of applications, covering everything from daily life to professional fields. In mobile phones, image sensors are integrated into the camera for taking photos and making video calls, enhancing the phone's multimedia capabilities. In surveillance systems, image sensors serve as a crucial component of the probe, used for real-time monitoring and security recording, effectively improving security capabilities. Furthermore, image sensors are widely used in digital cameras, tablets, laptops, drone monitoring, medical imaging (such as X-ray imaging and endoscopy), industrial inspection, and robot vision. By capturing and analyzing image information, image sensors provide critical visual data support for various applications.

[0004] Despite the significant achievements of image sensing devices in many fields, several problems remain to be solved. First, existing image sensing devices typically rely on rigid mechanical transmission during rotation, a process that is often not smooth enough, potentially leading to decreased accuracy and stability in image capture. Furthermore, the complex structure of the transmission mechanism increases manufacturing costs and maintenance difficulty. Second, photosensitive elements are inconvenient to use in strong light environments and are easily affected by light interference, resulting in degraded image quality or sensor failure. This limits the application of image sensing devices under certain extreme lighting conditions. In addition, existing image sensing devices have relatively weak adjustment capabilities, making it difficult to automatically adjust parameters to optimize image capture under different lighting conditions. These problems limit the performance and applicability of image sensing devices and require further technological innovation and optimization to solve. Utility Model Content

[0007] A sensor base has a cylindrical hollow cavity inside. An image sensor is disposed at the bottom of the cylindrical hollow cavity.

[0019] Figure 1 This is a schematic diagram of an image sensing device provided in an embodiment of the present invention. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Figure 1This is a schematic diagram of an image sensing device provided in an embodiment of the present invention. The present invention provides an image sensing device, comprising:

[0022] A sensor base 1 has a cylindrical hollow cavity. An image sensor 4 is disposed at the bottom of the cylindrical hollow cavity. A first polarizing mirror 3 is disposed at the top opening of the cylindrical hollow cavity. A second polarizing mirror 31 is disposed above the first polarizing mirror 3. The first polarizing mirror 3 and the second polarizing mirror 31 are of the same size and specifications. The second polarizing mirror 31 is connected to the first polarizing mirror 3 via a sliding groove and rotates concentrically on the first polarizing mirror 3. A first steering wheel 6 is rotatably connected to the bottom of the sensor base 1 via a first connecting rod 61. Two first connecting rods 61 are symmetrically arranged on the two sides of the sensor base 1 and the first steering wheel 6. A first airbag 5 is disposed between the sensor base 1 and the first steering wheel 6. A second steering wheel 8 is rotatably connected to the bottom of the first steering wheel 6 via a second connecting rod 81. Two second connecting rods 81 are symmetrically arranged on the two sides of the first steering wheel 6 and the second steering wheel 8. A second airbag 7 is disposed between the first steering wheel 6 and the second steering wheel 8. The line connecting the two first connecting rods 61 is perpendicular to the line connecting the two second connecting rods 81.

[0023] For example, the sensor base 1 is hollow inside, and the image sensor 4 is disposed at the bottom of the cylindrical hollow. A first polarizing mirror 3 is disposed at the top opening of the cylindrical hollow, and a second polarizing mirror 31 is disposed above the first polarizing mirror 3. The first polarizing mirror 3 is fixed to the top of the cylindrical hollow, and the second polarizing mirror 31 rotates concentrically on the first polarizing mirror 3. When the polarization of the two polarizing mirrors is in the same direction, the light is incident normally. When the external light is too strong, by rotating the second polarizing mirror 31, the polarization of the second polarizing mirror 31 and the first polarizing mirror 3 forms an angle, which increases the light filtering ability, reduces the light flux, and achieves the light reduction effect. The polarization angle between the second polarizing mirror 31 and the first polarizing mirror 3 changes infinitely with rotation, so the light flux can also be infinitely adjusted.

[0024] A first steering wheel 6 and a second steering wheel 8 are arranged below the sensor base 1, and are connected by a first connecting rod 61 and a second connecting rod 81. The rotation direction of the sensor base 1 and the first steering wheel 6 is perpendicular to the rotation direction of the first steering wheel 6 and the second steering wheel 8, ensuring that the sensor base 1 can rotate in any direction. The two first connecting rods 61 are symmetrically arranged at the midpoint of opposite sides in the same direction of the sensor base 1 and the first steering wheel 6, and a first airbag 5 is arranged on the adjacent side. When the first airbag 5 is inflated, the first airbag 5 is lifted up, and the sensor base 1 tilts in the opposite direction of the first airbag 5. When the first airbag 5 is deflated, the first airbag 5 collapses, and the sensor base 1 tilts in the direction of the first airbag 5. Two second linkages 81 are symmetrically arranged at the midpoints of opposite sides in the same direction of the first steering wheel 6 and the second steering wheel 8, and a second airbag 7 is arranged on the adjacent side. When the second airbag 7 is inflated, the second airbag 7 is lifted up, and the first steering wheel 6 tilts in the opposite direction of the second airbag 7. When the second airbag 7 is deflated, the second airbag 7 collapses, and the first steering wheel 6 tilts in the direction of the second airbag 7. Through the cooperation of the first airbag 5 and the second airbag 7, the sensor base 1 can be tilted in any direction.

[0025] In one possible embodiment, a motor 2 is provided on the top of the sensor base 1, and a friction wheel 21 is provided on the motor 2. The thickness of the friction wheel 21 is set to correspond to the thickness of the frame of the second polarizing mirror 31, and the friction wheel 21 is rotatably connected to the frame of the second polarizing mirror 31.

[0026] For example, the friction wheel 21 is driven by the motor 2, and the friction wheel 21 drives the second polarizing mirror 31 to rotate, thereby completing the adjustment of the amount of light entering the lens.

[0027] In one possible embodiment, the four sides of the first steering wheel 6 and the second steering wheel 8 are arranged to correspond to the lengths of the four sides of the sensor base 1. The first connecting rod 61 is rotatably connected to the sensor base 1 through the first rotating pin 62. The first connecting rod 61 is fixedly connected to the first steering wheel 6. The first connecting rod 61 is connected to the midpoint of the sides of the sensor base 1 and the first steering wheel 6.

[0028] The second link 81 is rotatably connected to the first steering wheel 6 via the second rotating pin 82, and the second link 81 is fixedly connected to the second steering wheel 8. The second link 81 is connected at the midpoint between the sides of the first steering wheel 6 and the second steering wheel 8.

[0029] The top and bottom of the first airbag 5 are respectively fixedly connected to the bottom of the sensor base 1 and the top of the first steering wheel 6. The first airbag 5 is located at the midpoint of the adjacent side of the side where the first connecting rod 61 is located.

[0030] The top and bottom of the second airbag 7 are fixedly connected to the bottom of the first steering wheel 6 and the top of the second steering wheel 8, respectively. The second airbag 7 is located at the midpoint of the adjacent side of the side where the second link 81 is located.

[0031] The first airbag 5 is provided with a first tracheal inlet 51, and the second airbag 7 is provided with a second tracheal inlet 71;

[0032] The first air pipe interface 51 and the second air pipe interface 71 are respectively connected to two variable pressure air pumps through two sealed pipes.

[0033] For example, the first air pipe interface 51 and the second air pipe interface 71 are respectively connected to two variable pressure air pumps through two sealed pipes, and are controlled separately to ensure that the sensor base 1 can be tilted in any direction.

[0034] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
