Description

The utility model relates to bells, lamps and microelectronic technology of bicycles and other light vehicles.

Bicycles are the main means of transportation in modern China. Ensuring traffic safety is a crucial matter involving hundreds of millions of Chinese people. At the same time, it is also very important to further improve the level of Chinese bicycles for Chinese bicycles to better enter the international market, to be in line with international standards. In order to improve the level of bicycles, in addition to the mechanical structure of bicycles, the automation and electronics of bicycle bells and lights are also the main aspects. Bicycle bell can be divided into following three types basically at present: the first kind is traditional mechanical bell and rubber-plastic bicycle bell. Their disadvantages are easy to rust, easy to malfunction, easy to hook up with other objects, etc. Second class is: air whistle type, as patent application number is 89219741.2,90223534.6, by compressed air, reed is made to vibrate, makes sound, obviously this car bell reliability is poor, the life-span is short. The third category is the whistle and lighting type. Representative patent applications include 88204974.7, 89203573.0, 90213855.3, 91215700.3 and 92226143.1. The 88204974.7 patent application adopts the commercially available integrated circuit KD-9561 produced by "Kant" company, but the power generation device is installed in the The wheels are connected to the lighting and whistle system with long wires. Obviously, the installation is inconvenient and the reliability is poor, and it is controlled by a manual switch without realizing automation. Touch, turn on the circuit, and realize automation. But in order to stop the alarm sound, the external plug must be inserted, and then another switch must be connected to make the horn sound. This "dual-purpose device" has poor reliability and is inconvenient to operate; although the 90213855.3 patent has the advantage of integrating the car bell and the lamp, it belongs to the mechanical type and does not realize automation. The 91215700.3 patent is a "sound and light combination installation device". The lighting lamp and the sounder are installed in the same shell, but the main light is installed on the front frame, the switch is installed on the bicycle handle, and the battery is installed on the center pole under the seat cushion. The tail light is installed on the rear fork rod, each part is connected by a long wire, and each function is controlled by a manual switch. Obviously, this "combination" has poor reliability, inconvenient installation, complicated operation, and poor practicability. Although the 92226143.1 "display" announced on May 19, 1993 has complete functions, it has many switches and inconvenient operation, and has not realized automation. In short, although the third category of products has taken a step towards the direction of electronization in terms of car bells and lights, they have not been automated due to their own many problems, so they have not been able to move toward practicality. So the bicycle bell still uses traditional mechanical bell almost at present, although many bicycle manufacturers have done many " beautification " to vehicle body, but the use of mechanical bell makes bicycle always can't get rid of traditional shackles.

The purpose of the utility model is to provide an automatic, integrated, small volume, low power consumption, high reliability, and practical light vehicle lamp and bell integrated synthesizer, so as to realize the "revolution" of the traditional bicycle bell. " and the "breakthrough" of the integration of car lights and bells.

The utility model is realized in the following ways.

The utility model includes an illumination system, an audio device, a light control device, a switch device, a power supply and a housing, and is characterized in that it also includes an application-specific integrated circuit USTC-909. The integrated circuit includes an oscillation circuit, a shaping circuit, a multi-stage frequency divider and a delay circuit, a latch and a logic gate circuit that can automatically complete lighting functions. According to the bright and dark state of the external environment, the light control device sends the signal to the logic gate circuit (T, U) through the shaping circuit of the special integrated circuit USTC-909, and the switching device (high-sensitivity trigger, patent No. 91207916.9) is based on the portable The stop and run state of the car, through the latch, logic gate circuit (O, P), multi-stage frequency divider and delay circuit of the special integrated circuit USTC-909, after passing through the logic gate circuit (I), also Send the signal into the logic gate circuit (T, U), and the logic gate circuit (T, U) determines the brightness and darkness of the lighting system according to the obtained signal. When driving at night, the synthesizer automatically sends out lighting light, and two signal lamps (signal lamps can also be set in the utility model) on the side also automatically send out flashing traffic signals. Triggered once, the delay time is determined by the delay circuit in the ASIC, continuous driving and continuous lighting. When driving in the daytime, the lights and signal lights are automatically turned off. When parking at night, the lights and signal lights are also automatically extinguished, thus realizing full automation.

The ASIC USTC-909 also includes clock circuits, shaping circuits, multi-stage counters and delay circuits, mixing circuits and logic gate circuits that can complete audio functions. Touch the switch to make the multi-stage counter and delay circuit work, and drive the audio device to sound. Since the multi-level counter and the delay circuit adopt multi-channel modulation, as well as the function of the delay circuit, as long as you touch the switch, it will automatically send out "Didididi-didididi-didididi-didididi-didididi-didididi-didididi- " car bell, every time you press it, it will ring automatically for 10 seconds (the time is adjustable).

Although the car light and the car bell are integrated, they do not interfere with each other, and each performs its own function. No matter whether the car light is on or off, as long as you touch it, the car bell will emit a 10-second car bell. The lights perform their function automatically whether the bell is ringing or not.

The application-specific integrated circuit USTC-909 of the utility model can be bipolar or MOS, and the MOS can be CMOS, NMOS or PMOS. ASIC USTC-909 can be single-chip, double-chip or multi-chip. The bell switch can be a touch switch, a membrane switch or other switches. The light control device can be a photocell or a photoresistor. The power supply can be a general battery of various sizes, or a rechargeable battery or a solar battery.

The utility model has the following characteristics:

1. Integration. Lighting lamps, signal lamps, and car bells are composed of a self-designed and developed ASIC USTC-909 and external related components, and are installed in the same injection molded shell, realizing the integration of car bells and lights.

2. Automation. Car lights: When driving in the dark at night, the forward lighting can be turned on automatically to emit continuous lighting, and the two red light-emitting tubes on the side also automatically send out flashing traffic signals at the same time; when driving in the daytime, the lights are automatically turned off, and when parking at night, It also automatically does not light up, realizing automation without switch control. When you need to sound the car bell, you only need to touch the touch switch lightly, and the car bell will sound intermittently and crisply for 10 seconds without pressing the switch all the time.

3. Low power consumption. The single-chip application-specific integrated circuit USTC-909 is adopted, and the optimized scheme is adopted in the circuit design; in the technical aspect, the CMOS process is adopted, so that the static power consumption and no-load power consumption reach the lowest value.

4. High reliability. ASIC USTC-909 adopts dual in-line package, and then integrates ASIC and external components to form a single "module". Experiments have shown that the "synthesizer" is still intact, works normally and achieves high reliability when a 200 rpm, 60-rotation routine test machine is used for a 300-hour routine experiment with harsh reliability.

5. Easy to install, small in size, convenient for mass production. The "synthesizer" only needs an ASIC USTC-909 and a few external related components, which can be formed by installing it on a micro printed circuit board. Small size, simple installation, convenient for mass production.

6. Strong practicability, low price, easy to popularize and use.
