Abstract
The utility model provides a remote controller with a trace ball. The remote controller comprises a shell, an upper cover which is fastened on the shell, a base, the trace wall, a light guide plate and an optical sensing element, wherein a circular hole is formed in the upper cover; the base is in a hollow cylindrical shape; a carrying groove is formed on the base; the trace ball is accommodated in the carrying groove of the base; the light guide plate is arranged on the other side, relative to the trace ball, of the base; the optical sensing element comprises a light source and a signal receiving part; and light rays which are emitted from the light source are guided to the surface of the trace ball through the light guide plate and then reflected to the signal receiving part through the trace ball. The utility model has the advantages that: a signal which is reflected on the surface of the trace ball is accurately sensed by the optical sensing element, so that the remote controller with the trace ball has high resolution; with the base, the trace ball can be conveniently arranged; and by arranging a plurality of rolling beads in the base, the trace ball can smoothly and accurately roll.
Description
Technical field
The utility model relates to a kind of telepilot, relates in particular to a kind of telepilot that is provided with trace ball.
Background technology
Telepilot is one of the most widely used electric component in people's daily life, and it is used for the duty of electric equipment products is controlled usually as the parts of attaching troops to a unit of electric equipment products.Just be furnished with telepilot such as the daily employed televisor of people, can realize the selection to television channel, the control of volume and the adjusting of other various functions through using a teleswitch.
The housing that the telepilot of prior art generally includes panel and cooperates panel to install is equipped with plurality of keys on the panel.The quantity of button is relevant with the function of electric equipment products, the electric equipment products that function is more, and the number of keys that needs on the telepilot is just many more.In the inner chamber that panel and housing surround, treatment circuit and radiating circuit are housed, after the button on the panel was pressed, the signal of generation was transmitted to electric equipment products by treatment circuit coding back through radiating circuit, thereby realizes the remote control to electric equipment products.
Along with further expanding of the function of electric equipment products, need the functional item of remote control also more and more, the number of keys of telepilot is therefore also just more and more.Like this, make the volume of telepilot increasing; Many buttons that are of little use also will occupy certain position on panel, make panel become more and more numerous and diverse, the difficulty that causes panel designs, making and panel to use; Simultaneously button increases and can cause button to diminish, and makes the user situation about pressing the wrong button in use occur, and causes using inconvenience; Simultaneously, the serviceable life of conductive rubber is limited.
The utility model content
In order to overcome the deficiency of above-mentioned prior art, the utility model provides a kind of telepilot that is provided with trace ball.
A kind of telepilot that is provided with trace ball; Comprise housing, be fastened on loam cake, pedestal, trace ball, LGP and the optics sensing element of said housing, be covered with circular hole on said, said pedestal is a hollow cylindrical; Said pedestal is provided with bearing groove; Said trace ball is placed in the bearing groove of said pedestal, and said LGP is arranged at the opposite side of said pedestal with respect to said trace ball, and said optics sensing element comprises a light source and a signal acceptance division; The light that said light source is launched is directed to the trace ball surface via LGP, and reflexes to the signal acceptance division via trace ball.
Further being improved to of the utility model is arranged with a plurality of ball grooves with arcs of recesses curved surface on the inwall of said bearing groove, be provided with ball in said a plurality of ball grooves.
Further being improved to of the utility model, the bottom of the bearing groove of said pedestal is provided with through hole, and said trace ball partly protrudes out the logical of pedestal.
Further being improved to of the utility model, said trace ball partly protrudes out the circular hole of loam cake.
Compared to prior art, the signal that the telepilot that is provided with trace ball of the utility model is reflected by the accurate sensing track ball of optics sensing element surface, resolution is high.Through pedestal trace ball is installed, easy for installation.A plurality of rolling pearls are set in pedestal, make the smooth and easy accurate rolling of trace ball ability.The telepilot package assembly that is provided with trace ball of the utility model is simplified, and installs easily, can carry out the move operation of cursor through trace ball easily, and is easy to use accurate.
Description of drawings
Fig. 1 is the telepilot assembling synoptic diagram that the utility model is provided with trace ball.
Fig. 2 is the telepilot decomposing schematic representation that the utility model is provided with trace ball.
Fig. 3 is the structural representation of the pedestal of the utility model telepilot of being provided with trace ball.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
See also Fig. 1 to Fig. 3, the utility model provides a kind of telepilot 10 that is provided with trace ball.Comprise housing 11, be fastened on the loam cake 13 of housing 11, pedestal 15, the trace ball 17 that is placed in pedestal 15, LGP 19, optics sensing element (figure does not show) and circuit board (figure does not show).
Loam cake 13 is fastened on housing 11, and loam cake 13 is provided with circular hole 131.Pedestal 15 is a hollow cylindrical, offers bearing groove 151 on it.Be arranged with a plurality of ball grooves 153 on the inwall of bearing groove 151 with arcs of recesses curved surface.Be provided with ball 21 in these a plurality of ball grooves 153.In the present embodiment, pedestal 15 is provided with a plurality of back up pads 155, and said back up pad 155 is radially extended to be used to carry trace ball along pedestal 15.Ball grooves 153 is opened on the said back up pad 155.When trace ball 17 was arranged in the bearing groove 151 of pedestal 15, trace ball 17 was held in this a plurality of ball grooves 153, thereby guaranteed that the smooth and easy of trace ball 17 accurately rolls.The bottom of the bearing groove 151 of pedestal 15 is provided with through hole 157.
Trace ball 17 is a spheroid, and when trace ball 17 was arranged in the bearing groove 151 of pedestal 15, its top part protruded out in the circular hole 131 of loam cake 13, and its underpart part protrudes out the through hole 157 of pedestal 15.LGP 19 is arranged between pedestal 15 bottom sides and the circuit board, and LGP 19 middle position orthogonal sets are equipped with collector lens 191, are used for reflected light is directed to the optics sensing element.
