Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Example 1

Figures 1 to 3 schematically show a mobile phone protective case according to Embodiment 1 of the present utility model. The following is an example of a mobile phone case dedicated to an Apple iPhone.

The mobile phone protective case includes a main body 1 of the protective case. The main body 1 of the protective cover is rectangular in shape, and is provided with a 30-pin data transmission plug 101 and a PCB board 106 . The PCB board 106 is equipped with an AT89S52 control chip 102 provided by Dongguan Xindu Plastic Products Co., Ltd. and 4 blue LED lights 103 connected in parallel. The data transmission plug 101 is electrically connected to the control chip 102 , and the control chip 102 is electrically connected to the LED lamp 103 . A reflective film 107 is provided on the protective cover body 1 , a light guide plate 108 is provided on the reflective film 107 , a panel 109 is provided on the light guide plate 108 , and openings corresponding to the PCB board 106 are provided on the reflective film 107 and the light guide plate 108 . The reflective film 107, the light guide plate 108 and the panel 109 are sequentially stacked on the back of the protective cover main body 1, and then welded into one body by a conventional ultrasonic welding machine.

As shown in Figure 3, two capacitors C1 and C2 are connected in parallel between the power supply pin of the control chip 102 and the ground wire to achieve the effect of denoising; a triode is connected between the signal output pin of the control chip 102 and the LED light 103 Q1, when the control chip 102 outputs a high level to the triode, then the triode Q1 will be turned on, so that the LED lamp 103 will be in a closed loop, and then the LED lamp 103 can emit light; when the control chip 102 outputs a low level to the triode Q1 level, then the triode Q1 is in a non-conducting state, so that the LED lamp 103 will be in a non-closed loop, and then the LED lamp 103 is extinguished; therefore, the triode Q1 can be used as a switch for turning on and off the LED lamp. Connecting resistor R1 between LED lamp 103 and ground wire can limit the current size, preventing the LED lamp from being burned out due to excessive current; connecting resistors R2 and R3 between the signal output pin of control chip 102 and the ground wire can limit the current size, preventing Excessive current burns the chip.

After the data transmission plug 101 is inserted into the corresponding 30-pin data transmission port on the mobile phone, the mobile phone will be connected with the control chip 102, and the control chip 102 will be started at the same time. When the mobile phone is in use or when there is an incoming call, the control chip 102 outputs a periodic gradient high level to the LED lamp 103, which is 2s in the present embodiment, so that the LED lamp 103 sends a gradient blue light; when the mobile phone is in In the standby state, the control chip 102 outputs a low level to the triode Q1, so that the LED light 103 goes out. The panel 109, the light guide plate 108 and the reflective film 107 can enhance the light effect of the mobile phone protective case. Therefore, in addition to the function of protecting the mobile phone shell, this mobile phone protective case can also realize the mobile phone working status prompt and incoming call prompt, and the gradient blue light effect can increase the aesthetic feeling, and finally realize the multiple functions of the mobile phone protective case. change.

When using the mobile phone protective cover of the utility model, the data transmission plug 101 of the mobile phone protective cover can be docked with the corresponding data transmission port on the mobile phone, and the use is very simple.

Example 2

Fig. 4 schematically shows a mobile phone protective case according to Embodiment 2 of the present utility model.

The difference between this embodiment and Embodiment 1 is that four LED lamp groups 110 connected in parallel are arranged on the PCB 106 . Each LED lamp group 110 is composed of LED lamps of three primary colors of red, green and blue. As shown in Figure 4, two capacitors C1 and C2 are connected in parallel between the power supply pin of the control chip 102 and the ground wire to achieve the effect of noise reduction; connecting a resistor between each LED lamp group 110 and the ground wire can limit the current Size, to prevent excessive current from burning out the LED lamp. The blue LED light, the red LED light and the green LED light in each LED light group 110 are respectively connected to the three signal output pins of the control chip 102 correspondingly. By controlling the output levels of the above three signal output terminals, the LED lamp group 110 can be controlled to emit red, blue, yellow, green, blue, purple, and white lights. For example, only output low level to blue LED lights, and output high level to other LED lights, then the LED light group will emit blue light; only output low level to red LED lights, and output high level to other LED lights level, then the LED lamp group 110 will emit red light; only output low level to the green LED lamp, and output high level to other LED lamps, then the LED lamp group 110 will emit blue light; output low level to blue and red LED lights, and output high level to green LED lights, then the LED light group 110 will emit purple light; only output low level to blue and green LED lights, and output high level to red LED lights level, then the LED lamp group 110 will emit cyan light; only output low level to the green and red LED lamps, and output high level to the blue LED lamp, then the LED lamp group 110 will emit yellow light; at the same time Output low level to the blue, green and red LED lamps, then the LED lamp group 110 will emit white light. Therefore, as long as the control chip 102 sends out a periodic gradual level change to the LED lamp group 110, the LED lamp group 110 will change color according to a predetermined time interval after being lit. Red, blue, yellow, green, blue, purple, and white lights make the mobile phone protective case emit brilliant gradient colorful lights. Others are the same as in Example 1. Therefore, in addition to the function of protecting the mobile phone shell, this mobile phone protective case can also realize the mobile phone working status prompt and incoming call prompt, and the gorgeous gradient colorful light effect can increase the aesthetic feeling, and finally realize the multiple functions of the mobile phone protective case. change. The mode of use is the same as in Example 1.

In other embodiments, the LED light 103 can also be red, yellow, green, cyan, purple, or white. And by adjusting the voltage at both ends of the LED light, it can also make it appear bright red, vermilion, orange, khaki, vine yellow, light yellow, lemon yellow, grass green, light green, raw brown, cooked brown, ocher, Violet, Crimson, Rose, Anthracite, Plain, Lily, Ultramarine, Cobalt Blue, Phthalo Green, or Dark Green are other colors. The panel 109 of the protective cover body 1 can also be provided with various patterns and patterns. Also can reach the beneficial effect of the utility model.
