Description

Technical Field

[0001] This application relates to the field of security camera power supply technology, and more specifically, to a security camera power supply device. Background Technology

[0002] Currently, industrial cameras are widely used. Many security cameras can only move back and forth within a single angle range and cannot rotate 360 ​​degrees, leaving blind spots in monitoring. Other cameras that can rotate 360 ​​degrees are designed using methods such as wire winding and flexible FPC, but they can only complete a rotation of slightly more than one revolution. Furthermore, the long-term reciprocating motion can easily cause metal fatigue in the wire winding, making it prone to breakage. Therefore, in applications that require long-term reciprocating motion for monitoring, the lifespan of such security camera products will be significantly limited, causing problems with power supply. Utility Model Content

[0003] The technical problem to be solved by the embodiments of this application is that security cameras are prone to metal fatigue due to long-term reciprocating motion, which leads to breakage and short service life, as well as difficulties in power supply.

[0004] To address the aforementioned technical problems, this application provides a power supply device for a security camera, employing the following technical solution: A security camera power supply device includes: A fixed housing is provided, on the outside of which a camera is mounted, and inside which an image acquisition card is installed. The image acquisition card is equipped with an image acquisition module and a WIFI image transmission module. The power supply assembly located at the bottom of the fixed housing includes: an external power rectifier base, a negative base, a positive base, a DC voltage regulator module, a positive power supply brush, and a negative power supply brush.

[0005] Furthermore, the image acquisition card, the image acquisition module, and the camera are electrically connected.

[0006] Furthermore, the bottom of the fixed housing is provided with an external power rectifier base, the top of the external power rectifier base is equipped with a negative base, the bottom of the fixed housing is equipped with a positive base that is used in conjunction with the negative base, the fixed housing is equipped with a DC voltage regulator module, a positive power supply brush is installed on one side of the bottom of the DC voltage regulator module, and a negative power supply brush is installed on one side of the positive power supply brush.

[0007] Furthermore, the positive base is connected to the positive terminal of the positive power supply brush and the positive terminal of the external power rectifier base, and the negative base is connected to the negative power supply brush and the negative terminal of the external power rectifier base.

[0008] Furthermore, both the positive and negative power supply brushes are made of graphite conductive material.

[0009] Furthermore, a power cord is installed at the outer end of the external power rectifier base, and a three-prong plug or USB connector is installed at the outer end of the power cord.

[0010] Furthermore, a rotary motor is installed at the top of the interior of the fixed housing, and a fixed shaft b is installed between the rotary motor and the image acquisition card.

[0011] Furthermore, the DC voltage regulation module is electrically connected to the image acquisition card and the rotary motor.

[0012] Furthermore, multiple heat dissipation slots are provided on the outer side of the fixed housing at the position opposite to the rotary motor.

[0013] Furthermore, a dustproof mesh is installed on the outside of each of the multiple heat dissipation slots. The dustproof mesh is a 600-mesh dustproof mesh.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages: First, power is supplied to the camera, image acquisition card, image acquisition module, WIFI image transmission module and rotary motor by contacting the positive and negative power supply brushes with the positive and negative bases, which replaces the traditional software power supply method. Moreover, the brushes have been widely used and maturely applied in motors, and have a longer service life than bent FPCs and wires. Secondly, the camera's 360° rotation in one direction, combined with the rotating motor, allows for a wider viewing angle, is not limited by the number of rotations, and has a longer lifespan. In addition, the original reciprocating motion camera has a large time difference at the left and right extremes, which makes image stitching difficult. However, the camera in this application rotates 360° in one direction, is not limited by reciprocating motion, has a small time delay between adjacent frames, and is easier to achieve panoramic algorithm fusion of 3D images.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This application provides a power supply device for a security camera, including: a fixed housing 1, a camera 101 mounted on the outside of the fixed housing 1, an image acquisition card 102 mounted inside the fixed housing 1, an image acquisition module 103 mounted on the image acquisition card 102, a WIFI image transmission module 104 mounted on the image acquisition card 102, and a power supply component disposed at the bottom of the fixed housing 1, the power supply component including: an external power rectifier base 2, a negative base 201, a positive base 202, a DC voltage regulation module 203, a positive power supply brush 204, and a negative power supply brush 205.

[0025] Power is supplied to the camera, image acquisition card, image acquisition module, WIFI image transmission module, and rotary motor through positive and negative power brushes in contact with the positive and negative bases, replacing the traditional software power supply method. The brushes are already widely used and maturely applied in motors, and have a longer service life than bent FPCs and wires. In conjunction with the 360° rotation of the rotary motor in one direction, the camera's viewing angle is wider, not limited by the number of rotations, and has a longer lifespan. In addition, the original reciprocating motion camera has certain difficulties in image stitching due to the large time difference at the left and right limits of recording. However, the camera of this application rotates 360° in one direction, is not limited by reciprocating motion, has less time delay between adjacent frames, and is easier to realize panoramic algorithm fusion of 3D images.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] Embodiment 1 of the security camera power supply device of this application The security camera power supply device of this application includes: a security camera power supply device, comprising: a fixed housing 1, a camera 101 installed on the outside of the fixed housing 1, an image acquisition card 102 installed inside the fixed housing 1, an image acquisition module 103 installed on the image acquisition card 102, a WIFI image transmission module 104 installed on the image acquisition card 102, and a power supply component disposed at the bottom of the fixed housing 1, the power supply component comprising: an external power rectifier base 2, a negative base 201, a positive base 202, a DC voltage regulation module 203, a positive power supply brush 204, and a negative power supply brush 205.

[0028] The image acquisition card 102, the image acquisition module 103, and the camera 101 are electrically connected.

[0029] When using camera 101, it first connects to the same local area network (LAN) WIFI network as the computer via WIFI image transmission module 104. The camera 101 and computer can be managed uniformly through the network system and cloud server. After user authorization, the camera 101, image acquisition card 102, image acquisition module 103, and WIFI image transmission module 104 are powered on for security monitoring. Camera 101 monitors and captures images of the security area. The image acquisition module 103 on image acquisition card 102 collects the captured images, which are then uploaded to the cloud server for archiving via WIFI image transmission module 104. When reviewing the monitoring footage, the user can operate the computer, inputting the required date and time period, thus providing anti-theft protection. Even if theft or loss occurs, the monitoring records can be used to find the thief or the person who took the items.

[0030] Example 2 Based on Embodiment 1, the bottom of the fixed housing 1 is provided with an external power rectifier base 2, the top of the external power rectifier base 2 is equipped with a negative base 201, the bottom of the fixed housing 1 is equipped with a positive base 202 that is used in conjunction with the negative base 201, the fixed housing 1 is equipped with a DC voltage regulating module 203, a positive power supply brush 204 is installed on one side of the bottom of the DC voltage regulating module 203, a negative power supply brush 205 is installed on one side of the positive power supply brush 204, the positive base 202 is connected to the positive terminal of the positive power supply brush 204 and the external power rectifier base 2, the negative base 201 is connected to the negative terminal of the negative power supply brush 205 and the external power rectifier base 2, and the DC voltage regulating module 203 is electrically connected to the image acquisition card 102 and the rotary motor 4.

[0031] During use, the camera 101, image acquisition card 102, image acquisition module 103, and WIFI image transmission module 104 are connected by a fixed housing 1 and an external power rectifier base 2, which are mounted together via a positive base 202 and a negative base 201. When power is required, the plug at the end of the power cord 3 is inserted into an external socket to connect the power supply. The current flows from the external power rectifier base 2, through the positive base 202, to the positive power supply brush 204, and then to the DC voltage regulator module 203. The driving voltage and current provided by the positive power supply brush 204 are adjusted by the DC voltage regulator module 203 to drive the camera 101, image acquisition card 102, image acquisition module 103, WIFI image transmission module 104, and rotary motor. The operating voltage and current are controlled by the negative power supply brush 205, which receives current from the DC voltage regulation module 203 to complete the circuit loop and returns it to the external power rectifier base 2 through the negative base 201 to power the camera 101, image acquisition card 102, image acquisition module 103, WIFI image transmission module 104 and rotary motor 4. The positive power supply brush 204 and negative power supply brush 205 contact the positive base 202 and negative base 201 to power the camera 101, image acquisition card 102, image acquisition module 103, WIFI image transmission module 104 and rotary motor 4, replacing the traditional software power supply method. The brushes have been widely used and maturely applied in motors and have a longer service life than bent FPCs and wires.

[0032] The external power rectifier base 2 is equipped with a power cord 3 at its outer end, and a plug is installed at the outer end of the power cord 3. When using the external power rectifier base 2, the plug at the outer end of the power cord 3 is inserted into an external socket to connect the power supply, allowing current to flow to the external power rectifier base 2. The power cord 3 is three meters long, with sufficient length provided to ensure the plug can be inserted into the socket without pulling on the external power rectifier base 2. The plug can be a three-prong plug 301 or a USB connector for easy power supply via a USB interface.

[0033] Both the positive power supply brush 204 and the negative power supply brush 205 are made of graphite conductive material. When in use, the positive power supply brush 204 and the negative power supply brush 205 are made of graphite conductive material. Graphite conductive material has excellent conductivity, and graphite has a very high melting point, which can maintain its physical and chemical properties unchanged under extreme temperatures. In addition, graphite has good resistance to most chemical substances and is not easy to react with acids, alkalis, etc. This means that the positive power supply brush 204 and the negative power supply brush 205 are not easily damaged during use, which helps to transmit current for power supply.

[0034] Example 3 Based on Embodiment 1 and Embodiment 2, a rotary motor 4 is installed at the top inside the fixed housing 1, and a fixed shaft b401 is installed between the rotary motor 4 and the image acquisition card 102.

[0035] When security monitoring is performed using camera 101, a start button and a stop button electrically connected to the rotary motor 4 are installed on the back of its fixed housing 1. When it is necessary to adjust the rotation and position of camera 101 to increase the monitoring range, the start button controls the rotary motor 4 to start working. The rotary motor 4 drives the fixed shaft b401 to rotate the fixed housing 1. At this time, the external power rectifier base 2 remains stationary, and the fixed housing 1 and the external power rectifier base 2 rotate, realizing the 360° rotation of the rotary motor 4 in one direction. This allows the camera 101 to have a wider viewing angle, is not limited by the number of rotations, and has a longer lifespan. In addition, the original reciprocating motion camera has a large recording time difference at the left and right limits, which brings certain difficulties to image stitching. However, the camera 101 of this application rotates 360° in one direction, is not limited by reciprocating motion, has a small time delay between adjacent images, and is easier to realize panoramic algorithm fusion of 3D images.

[0036] Multiple heat dissipation slots 402 are provided on the outer side of the fixed housing 1 at the position opposite to the rotary motor 4. During use, the rotary motor 4 will generate heat inside the fixed housing 1. The heat dissipation slots 402 can be used to dissipate the generated heat to the outside of the fixed housing 1 and carry away the heat through air flow, so that the rotary motor 4 can dissipate heat and cool down, and avoid the rotary motor 4 from overheating.

[0037] Each of the heat dissipation slots 402 is equipped with a dustproof net 403 on its outer side. The dustproof net 403 is a 600-mesh dustproof net. During the use of the heat dissipation slots 402, the dustproof net 403 can prevent dust from entering the fixed housing 1 from the heat dissipation slots 402, avoid the accumulation of dust in the electronic components inside the fixed housing 1, and prevent poor contact. This ensures that the camera 101 can be used for security monitoring normally.
