Description

Technical Field

[0001] The utility model relates to the technical field of monitoring cameras, in particular to a built-in micro heat dissipation structure. Background Art

[0002] In the field of user security, surveillance camera wing panels are not only common in the public field, but are also gradually being used in homes. They have the advantages of high sensitivity and vibration resistance, and play an important role in the field of security protection.

[0003] Existing surveillance cameras usually need to be protected when installed. The traditional protection method is to cover them with a closed metal shell. However, when they are powered on, they will generate heat. Although the simple metal cover plays a protective role, it is not conducive to heat dissipation and is prone to malfunctions in long-term operation. Utility Model Content

The hoisting connection frame is fixed on the top of the outer protective shell, and a rear side wire channel is provided on the rear side. A motor and a knob are also installed on the rear side wall of the outer protective shell. The camera body and the image head are installed in the outer protective shell through the movable mounting structure. The use of the movable mounting structure can make the installation and disassembly of the camera body more convenient. The cross-sectional L-shaped ring body is fixedly installed inside the outer protective shell through an integrally formed fixing frame, and a certain distance is provided between the two cross-sectional L-shaped ring bodies. The front and rear ends of the mounting ring are matched and placed in the two L-shaped cross-section ring bodies, and an integrally formed gear ring is provided on the middle outer wall. The gear ring extends from the spacing between the two L-shaped cross-section ring bodies and is installed in cooperation with the gear ring drive. The operation of the gear ring drive can drive the gear ring and the mounting ring on which it is located to rotate. A number of mounting columns are evenly distributed on the inner wall of the mounting ring. An inclined heat-absorbing fin is fixed on the top of the mounting column. The heat-absorbing fin is made of heat-absorbing material and is provided with through holes. The heat-absorbing fin itself has a heat-absorbing effect, and it can also rotate around the camera body under the rotation of the mounting ring. The rotation can achieve uniform heat absorption. At the same time, the heat-absorbing fin can also fan out wind when rotating, which can have a certain heat dissipation effect. A buckle groove is opened on the outside of the outer protective shell, and a transparent protective cover is buckled through it to protect the camera.

[0005] As a preferred technical solution of the utility model, a stepper motor is installed on the outer protective shell, and windows are opened on the left and right sides. A sealing plate is installed in the window through a torsion spring rotating shaft. A connecting ring is provided on the inner side of the sealing plate, and a rope is fixed on the connecting ring. The other end of the rope is fixed on the output shaft of the stepper motor. The rope can be tightened or released by the rotation of the stepper motor, so that the sealing plate can close and open the window under the action of the torsion spring. When opened, it helps air circulation and improves the heat dissipation effect, and can provide protection when closed.

[0006] As an optimal technical solution of the utility model, the movable mounting structure includes a bottom groove, a bottom lead screw and a U-shaped mounting rod. The bottom groove is opened on the inner bottom surface of the outer protective shell, and the bottom lead screw is rotatably installed in the bottom groove. It is driven by a knob arranged on the rear side wall of the outer protective shell. The vertical part of the U-shaped mounting rod is placed in the bottom groove and installed in cooperation with the bottom lead screw. The camera body is fixed on the horizontal part of the U-shaped mounting rod. By rotating the knob on the rear side, the bottom lead screw can be driven to rotate, thereby driving the U-shaped mounting rod to move along the bottom groove.

[0007] As a preferred technical solution of the utility model, the gear ring drive includes a driving shaft and a gear. The driving shaft is rotatably installed on the fixed frame on the lower right side in the forward and backward directions and is driven by a motor provided on the rear wall of the outer protective shell. The gear is fixedly installed on the driving shaft, and the gear is meshed with the gear ring. The rotation of the gear can drive the gear ring and the mounting ring on which it is located to rotate.

[0008] As a preferred technical solution of the utility model, mounting grooves are evenly distributed on the inner arc surface of the L-shaped ring body in cross section, and the mounting rollers are rotated therein, which can effectively reduce the friction of the mounting ring during rotation, thereby reducing the heat generated by friction.

[0009] The beneficial effects of the utility model are as follows: the movable mounting structure can be arranged to facilitate the installation and disassembly of the camera body; during the operation of the camera body, the motor on the rear side of the outer protective shell drives the drive shaft to rotate, so that the mounting ring drives the heat absorbing fins to rotate around the camera body, providing uniform heat absorption and heat dissipation, and can also drive air flow to fan the heat; the stepping motor can periodically open the sealing plate to leak out the window, thereby improving air circulation efficiency and improving heat dissipation effect.
