Abstract
Description
Technical Field
[0001] This utility model relates to the field of hard disk video recorder technology, and in particular to hard disk video recorders. Background Technology
[0002] A hard disk recorder, also known as a digital video recorder, is a computer system that records video from a hard disk, unlike traditional analog video recorders. It is often called a DVR or hard disk recorder because it uses a hard disk. It is a computer system that stores and processes images, and has the functions of long-term recording and audio recording, as well as remote monitoring and control. DVRs use digital recording technology and are far superior to analog monitoring equipment in terms of image processing, image storage, retrieval, backup, network transmission, and remote control. DVRs represent the future direction of television surveillance systems and are the preferred product for television surveillance systems on the market.
[0003] However, existing hard disk video recorders have the following problems during use: because a large number of components are integrated inside the casing of the hard disk video recorder, a lot of heat will be generated during the long-term operation of the recorder. Therefore, the hard disk video recorder is usually equipped with a cooling fan inside and has heat dissipation holes on the casing. However, since the bottom of the hard disk video recorder is in direct contact with the table surface, it is difficult to dissipate heat at the bottom of the recorder.
[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0005] A hard disk video recorder includes a hard disk video recorder housing and a hard disk video recorder motherboard disposed inside the hard disk video recorder housing. In addition to the heat dissipation holes commonly found on the side of the hard disk video recorder housing in existing designs, heat dissipation holes are also provided on the top of the hard disk video recorder housing.
[0006] It also includes a sealing grid frame, which is slidably disposed on the inner wall of the hard disk recorder housing. When the sealing grid frame slides to one limit of its travel, it is completely offset from the heat dissipation hole, allowing air to pass through the heat dissipation hole and enter the hard disk recorder housing. When the sealing grid frame slides to the other limit of its travel, it completely covers the heat dissipation hole and forms a seal with the hard disk recorder housing.
[0007] The drive unit is located inside the housing of the hard disk recorder and has at least one linear motion component connected to the sealed grid frame.
[0008] Preferably, the sealing grid frame includes a main frame rod and side baffles fixed on the main frame rod. The upper end surface of the side baffles is provided with a rubber layer and is attached to the inner top wall of the hard disk recorder housing to achieve waterproof sealing.
[0009] Preferably, the drive unit is a linear electric actuator, wherein the movable end of the linear electric actuator is connected to the main frame rod.
[0010] Preferably, the drive unit includes a shim screw rotatably disposed inside the housing of the hard disk recorder and a servo motor for driving the screw, and also includes at least one screw-matching nut block fixed on the main frame rod. The screw-matching nut block and the screw are threadedly connected. The servo motor drives the screw to rotate, and the screw and the screw-matching nut block drive the sealing grid frame to slide through the movement of a helical pair.
[0011] Preferably, it also includes a temperature monitoring module and a microcontroller controller, wherein the temperature monitoring module is located at a designated position inside the housing of the hard disk recorder for monitoring the temperature of a designated area, and the microcontroller controller, the temperature monitoring module, and the drive unit are wiredly connected. When the microcontroller controller detects that the temperature monitoring module has reached a designated safety threshold temperature, it controls the drive unit to operate.
[0012] The advantages and positive effects of this utility model are:
[0013] During use, the device can actively adjust its operation based on the actual heat dissipation of the DVR motherboard. When the heat reaches a safe threshold, the ventilation holes on the top of the DVR casing are opened to allow hot air to escape naturally. The internal cooling fan of the DVR motherboard also quickly expels the hot air, resulting in rapid cooling. When the DVR motherboard is not in operation, the ventilation holes are sealed by the side baffle to effectively prevent water and dust damage. Attached Figure Description
