Television sets have been popularized to every household at present, and television remote controllers have become an inseparable tool in people's amateur cultural life. Because it is operated by hand and the frequency of use is high, people generally hope that the remote controller has functions such as simplicity and flexibility, easy manipulation, long service life, and dustproof. The existing remote controller is mainly composed of a housing, a rubber button substrate, a control circuit board, etc. By pressing the rubber button, the corresponding functional circuit on the control circuit board is connected and a signal is emitted to achieve the purpose of remote control of the TV. The current remote controller generally has a power key, a number key, and conventional function keys including a volume control key, a channel switch key, a MUTE (mute) key, a VIDEO (video recording) key, etc., including a MENU (menu) key, a TV (television) key, etc. ) key, INFO (information display) key, EXIT (exit) key and other function mode selection keys, including GAME (game) key, DUAL I-II (stereo switching) key, P-SIZE (image size) key, SLEEP (sleep timing) key, TURBO (sound effect enhancement) key, S.MENU (sound menu) key, S.MODE (sound mode) key, P.MODE (picture mode) key and other advanced function keys and four-direction key and the ENTER (OK) key to form the navigation key. But the commonly used control keys are basically the POWER (power) key, which is used to adjust the volume, change the channel, etc., the normal function keys, control the up, down, left, right direction and ENTER (OK) navigation keys, the exit key and the menu key etc., but these keys are arranged together with other keys, which are often not easy to find and operate because of their unprotrusive and non-concentrated positions. It is not obvious, if the force is too small, there will be problems of insensitivity and ineffective operation. In addition, the remote control has no fixed position, and it is placed everywhere after use. Moreover, many of its keys are exposed, and it is easy to be contaminated with dirt and dust by hand touch and environmental pollution, affecting performance and life.

Detailed ways

Figures 1-3 show a rocker-type dust-proof remote control, including a housing 1, a rubber keypad 15, and a control circuit board 16 inside the housing. The rubber keypad 15 is provided with a power key 10 and a number key 14. , conventional function keys 13, mode selection keys 12, advanced function keys 11, and navigation keys 6 for controlling direction and carriage return, etc. It is characterized in that the upper surface of the housing 1 is provided with an openable cover 2, and the upper surface of the cover 2 There is a window corresponding to the position of the commonly used keys; the commonly used keys described here include the power key 10, the volume control key 3, the channel switching key 4, the exit key 7, the menu key 5 and the navigation key 6, and corresponding to these commonly used keys, windows are respectively set. 10-1, window 3-1, window 4-1, window 7-1, window 5-1 and window 6-1. The window can be covered with colorless transparent plastic film, such as the window 3-1 and window 4-1 of volume control key 3 and channel switch key 4 are respectively covered with colorless transparent plastic film 3-2 and 4-2, In this way, the airtightness of the remote controller can be improved, the dustproof effect is better, and the normal use of the control keys is not hindered. The navigation key 6 is an integrated structure molded on the rubber key board substrate 17, and consists of a cross-shaped convex strip 6-7 and an arc-shaped convex strip 6-2 connected to the four ends of the cross-shaped convex strip 6-7. . The bottom surface of position 6-6 is provided with grooves, which are respectively groove 22, groove 23, groove 24, groove 25 and groove 26, and the graphite block 27 connecting the circuit contact is fixedly arranged in the groove. Two graphite blocks 27 connecting circuit contacts are respectively fixedly arranged in the grooves 22-25 provided on the bottom surface of the four arc-shaped protruding belts. According to the existing remote controller control circuit board design, two graphite blocks 27 can be used to further Improve contact reliability. The effect of groove is to make the graphite block 27 that is fixedly installed on it keep a distance with the control circuit board contact, like this, do not contact under the normal state, and graphite block 27 connects contact point when pressing, and circuit is connected, and when not pressing, then in rubber Automatic return under the action of the board. The surface of the housing 1 is provided with a direction mark 28 above the navigation key 6, and a movable hole 8 with a gap with the rocker is provided around the rocker 6-8; this is convenient for the rocker 6-8 to freely swing in four directions. Here, the arc-shaped convex strips 6-2, 6-3, 6-4, and 6-5 are equivalent to the four direction keys up, down, left, and right, the intersection point 6-6 is equivalent to the ENTER key, and the four-way controllable navigation rocker 6 -8 combines the functions of the four direction keys and the centered ENTER key. As shown in Figure 3 (a), (b), (c), when the rocking bar 6-8 is pushed up, the upper circular arc-shaped convex strip 6-2 connected by the cross-shaped convex strip 6-7 passes through the graphite at the bottom. Block 27 connects the corresponding contacts in the control circuit board, sends a signal, and realizes the corresponding function of moving the highlighted cursor in the screen display menu upwards. In the same way, the same goes for downward, leftward, and rightward functions; press the joystick 6-8 now , the intersection point 6-6 in the center of the rocking bar is connected to the corresponding contact point in the control circuit board through the graphite block 27 at the bottom, so as to realize the function of determining (ENTER). The rocking bar 6-8 is integrally molded on the rubber key board substrate 17 along with the navigation key 6, and the elasticity of the rubber itself makes it return to its original position after being pressed each time to ensure the implementation of its function. A suspension ring 9 is provided at the bottom of the housing 1 . In this way, the remote controller can be hung near the TV set after use, which is easy to take and use. One side of the open-close cover 2 is provided with a hinge shaft 18 sleeved into the hinge sleeve 19 of the housing 1, and the other side is provided with a protrusion 20 that can be clamped on a clip edge 21 provided on the housing 1. . When the buttons under the cover 2 are not used, the cover 2 can be closed, and the protrusion 20 is snapped into the clip edge 21 to be firmly fixed on the housing 1 .

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the shape, material and structure of the present utility model in any way. All simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the technology of the present invention.
