Description

Structure of digital video recorder

The present invention is a digital video recorder which digitally records a video signal and an audio signal by controlling the signal processing according to the operation of the control panel by electrically connecting a plurality of PCB boards to the video / audio input / output terminals and the control panel and the casing. The present invention relates to a structure, in particular, by fixing the storage medium at a predetermined distance from the bottom surface of the casing so that the heat generated from the storage medium can be quickly dissipated, so that the storage medium does not overheat even if used for a long time. The structure of the digital video recorder to allow the product to be further miniaturized by allowing the extension, and the storage medium can be disposed on the upper portion of the PCB substrate embedded in the casing to reduce the built-in space.

Digital Video Recorder (DVR: Digital Video Recorder) is also called Digital Video Storage Device. Video cassette recorder (VCR) is used to repeat the recording several times. While it is cumbersome to use, such as replacing, it uses hard disks (HDD) or digital video disks (DVD) instead of video tapes, so it is easy to play back or retrieve the saved screen.

In addition, since the DVR is stored as a digital signal, it is very convenient to edit and transmit images.

The DVR has a structure that allows the hard disk to be attached and detached, so that video and audio data can be recorded and stored in a large capacity so that the storage space is insufficient or the pre-stored video and audio data can be replaced without needing to be copied from other storage media. There is convenience.

Therefore, since the recorded video data and audio data are stored in a freely movable hard disk, the portable video data can be easily carried and then mounted and connected to a remote PC or DVR to reproduce the stored video data and audio data.

However, the conventional DVR has a problem of high theft rate because it is made of a front loading method in which a hard disk can be mounted or removed from the front control panel like the VCR.

In other words, hard disk used in DVR should store video data or audio data in large capacity. Therefore, data storage space should be relatively larger than hard disk used in general-purpose PC, as well as movies, music videos, and CCTVs. Surveillance video data is operated by a combination of search and indexing functions. Therefore, the transmission speed and processing speed of hard disks are also higher than those used in general-purpose PCs. Expensive hard disks are located on the front control panel, so that they are easily stolen.

In addition, most of the hard disks have a rectangular shape. When the hard disk is designed to be loaded to the front, it is necessary to dissipate heat generated from the hard disk, thereby preventing interference with the PCB board. It should be designed, and thus, the number of parts embedded in the casing is not large, but only the casing becomes large, resulting in a problem that the storage and management are not easy, and the manufacturing cost is increased.

In order to solve the above problems, the present invention is to design the casing and the arrangement of the components so as not to interfere each other for each component embedded in the casing, and at the same time to allow the heat generated from the hard disk to be quickly dissipated. Of course, it also provides an object to facilitate the removal of the hard disk and to reduce the theft rate.

Preferably, the jaw 124 is included.

Hereinafter, the structure and operation of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 2.

First, as shown in FIG. 1, the control panel 102 is coupled to the front surface of the lower casing 103b so that the DVR (Digital Video Recorder) can perform various functions such as recording, playback, and stop according to a user's selection control. It is supposed to be.

Here, the support bracket 109 is supported and fixedly coupled to the bottom surface 107 of the lower casing 103b by the bridge 108 in a state spaced apart from the bottom surface 107 by a predetermined distance. The coupling piece 110 is bent upwardly at the front and rear ends of the upper portion, and the receiving body 113 coupled to the upper portion of the support bracket 109 is inserted between the coupling pieces 110 and fixed by bolting to the coupling piece 110. It is done.

When the upper casing 103a shown in FIG. 1 is bolted to the lower casing 103b, the openings 106 of the upper and lower casings 103a and 103b are disposed at the same position to accommodate the accommodating body 113. An access space for inserting the storage medium 105 toward the side is secured.

In addition, as shown in the inner surface of the receiving body 113, the guide 116 is protruded toward the inside, the guide 116 is formed in the guide grooves 117 formed on both sides of the storage medium 105 is inserted By inserting into a) so that the storage medium 105 can be guided in a linear direction, the input and output port 114 formed at one end of the storage medium 105 and the input / output slot 112 formed at one end of the receiving body 113 are mutually At the same time, it is guided so that it can be inserted into a position, and downwardly supports the inserted storage medium 105 to prevent the storage medium 105 from swinging up and down or changing its position in the entrance / receiving portion 111.

On the other hand, the input and output port 114 of the storage main body 115 is guided into the entrance and reception portion 111 is to be coupled to the input and output slot 112, the concave and convex coupling is made by the user to apply a force.

However, as described above, when a user manually applies a force to the storage medium 105 to insert the input / output port 114 into the input / output slot 112, the uneven coupling is loosened when parts are broken or frequently used. This will occur.

Therefore, in the present invention, the storage main body 115 and the input / output port 114 inserted into the entrance / receiving portion 111 have a stopping state in proximity to the input / output slot 112, and the stopping state is the present invention. It is achieved by the fixing means of the storage body 115 presented in.

That is, the tip of the locking jaw 124 of the handle 120 introduced into the stopper 122 protruding from the upper end of both inner side surfaces of the other end of the receiving body 113 is interrupted and stopped as shown in FIG. 114 and the input and output slot 112 is to be placed just before the uneven coupling.
