Abstract
The utility model relates to the technical field of remote control, in particular to a remote control receiving device of a television. Aiming at the defect of the low sensitivity of the remote control receiving device in the prior art, the utility model discloses the remote control receiving device with high sensitivity. The technical scheme has the following key points: the remote control receiving device comprises a remote control head and a light guide column; the remote control head is arranged on a main board; the light guide column is designed on a front frame and is over against the remote control head; and the surface of the light guide column is protruded out of the front frame. Furthermore, the surface of the light guide column is a cambered surface. The remote control receiving device has the benefits of high remote control receiving sensitivity, being convenient for users to remote control, and being suitable for the remote control of display equipment.
Description
Technical field
The utility model relates to the telecontrol engineering field, relates to a kind of TV remote-control receiving system specifically.
Background technology
For television set, generally all be that the remote control head is fixed on the TV SKD, in order to receive remote signal fully, all be to adopt the mode that on the television set front plane frame, increases the leaded light post to guide infrared remote control signal.Remote-receiver of the prior art comprises remote control head, leaded light post; Described remote control head is arranged on the mainboard, and the leaded light post designs in front on the frame, and over against the remote control head, described leaded light post surface is the plane, and flushes with front plane frame.The user is using a teleswitch when television set carried out straighforward operation, the infrared remote control head of remote controller need be faced the leaded light post of television set, if the inclination certain angle a part of infrared light that the infrared remote control hair penetrates then can occur and be blocked by front plane frame and cause the situation that remote-control sensitivity is low.
The utility model content
Technical problem to be solved in the utility model is: at the low shortcoming of remote-receiver remote-control sensitivity of the prior art, propose a kind of highly sensitive remote-receiver.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the TV remote-control receiving system comprises remote control head and leaded light post; Described remote control head is arranged on the mainboard, and the leaded light post designs in front on the frame, and over against the remote control head, described leaded light post surface protrudes from front plane frame.
Further, described leaded light post protrusion front plane frame partly is a cambered surface.
Described cambered surface is sphere or ellipsoid or parabola.
The beneficial effects of the utility model are: the remote control receiving sensitivity is provided, makes things convenient for user's straighforward operation.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Among the figure, 1 is the remote control head, and 2 is the leaded light post, and 3 is mainboard, and 4 is front plane frame.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model is with respect to prior art, the leaded light post has been carried out Change In Design, originally the surface flushes with front plane frame, change into the surface is protruded from front plane frame, and further, surface design can also be become the convex parabola, like this can be so that the leaded light post focuses on more remote control infrared ray, guarantee the abundant reception of remote control head, and then improve remote-control sensitivity.
Embodiment:
As shown in Figure 1, the TV remote-control receiving system in this example comprises remote control 1 and leaded light post 2; Described remote control 1 is arranged on the mainboard 3, and leaded light post 2 designs in front on the frame 4, and over against remote control 1, described leaded light post 2 surfaces protrude from front plane frame 4, and leaded light post 2 surfaces are the convex parabola.
Its operation principle is: the user is by the infra-red remote control sign indicating number of remote controller emission, is directed into remote control 1 by leaded light post 2, and remote control 1 a receiving infrared-ray remote control mode is also passed to mainboard 3 identification of decoding.Because leaded light post 2 is designed to protrude from front plane frame 4, just enlarged the range of receiving of infra-red remote control sign indicating number, avoid being blocked by front plane frame 4, and the surface design of leaded light post 2 is become the convex parabola, increased the surperficial contact range of infra-red remote control sign indicating number and leaded light post 2, thereby further increased the remote control receiving sensitivity, even, still can guarantee the high sensitivity that remote control receives with tilt certain angle operation of remote controller.Through after repeatedly putting into practice on the liquid crystal TV set LT52900FHD, find to be increased to ± 35o by original remote control angle ± 18o, be increased to 22 meters by 15 meters of original remote control distances.
Claims (5)
1. the TV remote-control receiving system comprises remote control head and leaded light post; Described remote control head is arranged on the mainboard, and the leaded light post designs in front on the frame, and over against the remote control head, it is characterized in that: described leaded light post surface protrudes from front plane frame.
2. TV remote-control receiving system as claimed in claim 1 is characterized in that: described leaded light post protrudes front plane frame and partly is cambered surface.
3. TV remote-control receiving system as claimed in claim 2 is characterized in that: described cambered surface is a sphere.
4. TV remote-control receiving system as claimed in claim 2 is characterized in that: described cambered surface is an ellipsoid.
5. TV remote-control receiving system as claimed in claim 2 is characterized in that: described cambered surface is for parabolic.
