Embodiment
Fig. 1 ~ 3rd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 3 pair of the utility model of accompanying drawing.
Be depicted as a kind of mixed light that uses of the present utility model as the safe display panel structure synoptic diagram of the treadmill of backlight as Fig. 1 ~ 2, comprise LCD display panel 1, backlight assembly 2 and drive circuit board 3.LCD display panel 1 is rectangle, real-time status to the treadmill operation shows, LCD display panel 1 is divided into three zones from top to bottom: the zone of the top is used for showing the current operational mode of treadmill, zone line area maximum, be used for showing the continuous time of running of person taking exercise, the zone of below can be divided into three little viewing areas from left to right again, is respectively applied to show the calory count of treadmill real time kinematics speed, consumption and the gradient of treadmill.
The drive circuit board 3 that is similarly rectangle is fixed on the back side of backlight assembly 2, links to each other with backlight assembly 2, and the Micro Controller Unit (MCU) driving circuit U 2 driving backlight assemblies 2 that are welded on the drive circuit board 3 are luminous.Four jiaos at drive circuit board 3 have four fixed orifices, are convenient to drive circuit board 3 and the backlight assembly 2 that is fixed thereon and LCD display panel 1 fixing.After fixedly finishing, drive circuit board 3 is positioned at treadmill instrument housing inside.
As shown in Figure 3, a kind of mixed light that uses of the present utility model is made up of following components as the drive circuit board 3 of the safe display panel of treadmill of backlight: treadmill appliance circuit U1, Micro Controller Unit (MCU) driving circuit U 2 and as the Tricolor LED of backlight assembly 2.Be integrated with three can be independently luminous PN junctions in the Tricolor LED, thereby three independent LED D1 ~ D3 have been formed, light emitting diode D1 ~ D3 can send alone color be followed successively by the red, green, blue look light, based on the principle of three primary colours, send the light time of varying strength as light emitting diode D1 ~ D3, can form various mixed light, this mixed light is the backlight that is used for illuminating LCD display panel 1 that sends as backlight assembly 2.
From treadmill appliance circuit U1, draw two power leads and link to each other with Micro Controller Unit (MCU) driving circuit U 2, as the power supply of Micro Controller Unit (MCU) driving circuit U 2.From treadmill appliance circuit U1, draw two signal line simultaneously and link to each other with two input ends in the Micro Controller Unit (MCU) driving circuit U 2, by two signal line the real time kinematics rate signal of treadmill is passed to Micro Controller Unit (MCU) driving circuit U 2.Three output terminals in the Micro Controller Unit (MCU) driving circuit U 2 link to each other with the anode of light emitting diode D1 ~ D3 successively by corresponding current-limiting resistance (not drawing among the figure), and to be its common port link to each other with common ground end GND in the Micro Controller Unit (MCU) driving circuit U 2 negative electrode of light emitting diode D1 ~ D3.
In the present embodiment, the light emitting diode D1 ~ D3 as backlight assembly 2 is respectively applied to show ruddiness, blue light and green glow.Micro Controller Unit (MCU) driving circuit U 2 is for being core with the single-chip microcomputer, drive the light that light emitting diode D1 ~ D3 sends varying strength separately by the real time kinematics speed synchronizing signal from treadmill appliance circuit U1 that receives, make Tricolor LED send the mixed light of different colours, i.e. the backlight as LCD display panel 1 that sends of backlight assembly 2.Under the driving of Micro Controller Unit (MCU) driving circuit U 2, backlight assembly 2 can send the light of different colours according to the change correspondence of real time kinematics speed, corresponding different exercise intensity.The mixed light of backlight assembly 2 shows is transferred to warm-toned gradually changing from cool colour, and corresponding growing from weak to strong of exercise intensity makes the person taking exercise show more intuitively real-time exercise intensity.
The concrete course of work is as follows: when the person taking exercise starts treadmill and carries out, the LCD display panel 1 that is installed on the treadmill casing can show some states of current treadmill, for example: the calorie of the time of the residing pattern of treadmill, operation, real time kinematics speed, consumption and the gradient of treadmill.The backlight assembly 2 that meanwhile is fixed on LCD display panel 1 back side can send light, as the backlight of LCD display panel 1.This moment, treadmill appliance circuit U1 can be passed to the real time kinematics rate signal Micro Controller Unit (MCU) driving circuit U 2, playing the single-chip microcomputer of central role in the Micro Controller Unit (MCU) driving circuit U 2 can analyze the real time kinematics rate signal that treadmill appliance circuit U1 sends by built-in program, and driving is carried out the luminous of varying strength as three independent LED D1 ~ D3 in the Tricolor LED of backlight assembly 2, carry out the demonstration of mixed light, the light of the different colours that sends by backlight assembly 2 is to represent exercise intensity corresponding under this real time kinematics speed.
When exercise intensity is low, Micro Controller Unit (MCU) driving circuit U 2 can drive the light demonstration that Tricolor LED sends cool tone, when exercise intensity was higher, Micro Controller Unit (MCU) driving circuit U 2 can drive Tricolor LED and send warm-toned light demonstration, in order to the person taking exercise on the real-time prompting treadmill.
In the present embodiment, treadmill appliance circuit U1 is used for carrying out the circuit part that speed shows in the former treadmill, Micro Controller Unit (MCU) driving circuit U 2 for the single-chip microcomputer be core carry out the luminous circuit part of colour mixture in order to drive Tricolor LED.
In the present embodiment, the single-chip microcomputer in the Micro Controller Unit (MCU) driving circuit U 2 has played comparatively common control function, so the most of single-chip microcomputer that can see on the market all can be realized by programming.In the present embodiment, employing be the MCS-51 Series chip, can also select other Series chip as required, as AVR series monolithic, PIC series monolithic, MSP430 series monolithic and STM32 series monolithic.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
