After receiving the information, the central processing/controlling unit will activate the indicator to emit strong light or activate the alarm unit to emit alarming sound. In addition, the portable controller can remotely control the indicator to emit strong light or the alarm unit to emit indicating sound so as to help a user in finding the location of the car.

BACKGROUND OF THE INVENTION 
The present invention relates to a car location indicating and burglarproof 
alarm device, and more particularly to a car-used burglarproof alarm 
device which is designed as a main frame with a simple pattern. The main 
frame is equipped with a clip member enabling a user to easily mount the 
main frame on a sunshade or instrument panel of the car by way of 
clipping. A user can operate a portable controller to easily control the 
burglarproof alarm. Therefore, the shortcomings of the conventional 
car-used burglarproof alarm, that is, layout of complicated wires and 
drilling operation are eliminated. An indicator is additionally disposed 
on the car body, which can flicker under remote control of the portable 
controller so as to help in finding the location of the car. 
A conventional car-used burglarproof device includes a control box and a 
remote controller. The control box is installed on the car body and a user 
via the remote controller activates or turns off the burglarproof device. 
In the case that the car body is shook, shocked or intruded, the 
burglarproof device according to the signal of a sensor activates an alarm 
to emit alarm sound and inform the user of the intrusion or shock. 
In practical use, the above car-used burglarproof device has some 
shortcomings as follows: 
1. The complicated wires of the car-used burglarproof device must be one by 
one mounted on the main circuit of the car by a specialist. In addition, 
only by means of drilling or embedding of the wires, the control box can 
be fixed in the car. Such installation is time-consuming and inconvenient. 
2. The respective wires of the car-used burglarproof device are connected 
with the main circuit of the car body and the car-used burglarproof device 
is powered by the battery of the car. Therefore, under the condition that 
the burglarproof device is activated while the car is not started, the 
load on the battery will be increased and the discharging of the battery 
will be speeded. As a result, it will be difficult or even impossible to 
start the car and the battery will need to be replaced by a new one. 
On the other hand, the conventional car-used burglarproof device often has 
an additional car-searching function. The car-used burglarproof device is 
electrically connected with the head light, light set or the horn of the 
car. Under a circumstance of poor illumination or complicated environment, 
a user can use the remote controller to control a receiver on the car 
body, which turns on the head light, light set or horn to flicker or 
intermittently emit sound for helping in locating the car. In order to 
achieve the above function, the wires of the burglarproof device must be 
laid in the car in a complicated manner. Moreover, in the case that the 
car is parked among a number of cars and the head light of the car is 
positioned at a relatively low position, the location of the car will be 
difficult to find. 
SUMMARY OF THE INVENTION 
It is therefore a primary object of the present invention to provide a car 
location indicating and burglarproof alarm device including a main frame 
and a portable controller. The main frame is equipped with a clip member 
enabling a user to easily mount the main frame on a sunshade or instrument 
panel of the car by way of clipping. Therefore, the shortcomings of the 
conventional car-used burglarproof alarm, that is, layout of complicated 
wires and drilling operation are eliminated. The portable controller is 
used to remotely control and activate or turn off the burglarproof alarm 
of the main frame. When a user via the portable controller gives the main 
frame a command of activation, a built in shock sensor of the main frame 
will sense the abnormal situations of the car body. In the case of 
shaking, collision or intrusion, the shock sensor will immediately send 
the abnormal information to a central processing/controlling unit which 
will activate an indicator to emit strong light or activate the alarm unit 
to emit alarming sound. By means of the light and alarming sound, the user 
can be clearly indicated of the situation and location of the car. 
It is a further object of the present invention to provide the above car 
location indicating and burglarproof alarm device in which the main frame 
is installed at a higher position in the car. Via a key pad of the 
portable controller, a user can directly remotely control the main frame 
to activate the indicator to intermittently emit strong light or activate 
the alarm unit to emit alarming sound so as to effectively help a user in 
finding the location of the car in a complicated or dim environment. 
The present invention can be best understood through the following 
description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Please refer to FIGS. 1 to 4. The present invention is composed of a main 
frame 1 and a portable controller 2. The main frame 1 includes a central 
processing/controlling unit 11, a signal receiving unit 12, a shock sensor 
13, an indicator 14 and an alarm unit 15. The main frame 1 is equipped 
with a clip member 18 enabling a user to easily mount the main frame 1 on 
a sunshade or instrument panel of the car by way of clipping. The portable 
controller 2 includes a microprocessing unit 21, signal transmitting unit 
22 and a key pad unit 23. The portable controller 2 is used to activate or 
turn off the burglarproof alarm of the main frame 1. When a user via the 
key pad unit 23 of the portable controller 2 gives the main frame 1 a 
command of activation or turning off, the microprocessor 21 of the 
portable controller 2 further processes the signal transmitted by the key 
pad unit 23 and determines the code previously set for activating or 
turning off the burglarproof alarm. The code is further transformed by the 
signal transmitting unit 22 and transmitted to the main frame 1. The 
signal transmitting unit 22 is composed of an audiofrequency controller 
221 and a radio transmission unit 222. After the microprocessor 21 sends 
the code to the audiofrequency controller 221, through frequency 
oscillation thereof, the code is transmitted by the radio transmission 
unit 222 to be received by the main frame 1. After the signal receiving 
unit 12 of the main frame 1 receives the signal transmitted from the 
portable controller 2, the signal is sent to the central 
processing/controlling unit 11 for processing. In the case of activation 
command, the central processing/controlling unit 11 will activate the 
shock sensor 13 which serves to sense the abnormal situations of the car 
body, such as shaking, collision or intrusion. The shock sensor 13 also is 
able to immediately send the abnormal information to the central 
processing/controlling unit 11. After receiving the information, the 
central processing/controlling unit 11 will activate the indicator 14 to 
emit strong light or activate the alarm unit 15 to emit sound or even 
through an externally connected horn 16 on outer side of the car, the 
alarm unit 15 can emit more apparent alarming sound. By means of the 
alarming sound or flickering light, those persons around the car can be 
informed of the abnormal situations and the location of the car. The 
externally connected horn 16 is mounted at an external position of the car 
by way of laying the wire so as to enhance the volume of the alarm sound. 
In addition, the indicator 14 of the present invention includes high 
illumination bulbs mounted in a transparent cover 141 of the main frame 1. 
Via the key pad unit 23 of the portable controller 2, the indicator 14 can 
be activated by the main frame 1 in the car to emit strong light or the 
alarm unit 15 can be activated to emit alarming sound so as to indicate 
the user of location of the car. This is very helpful in searching the car 
in a complicated or dim environment. Moreover, the main frame 1 is powered 
by a power source 17 for activating and maintaining the functions thereof. 
The power source 17 includes several batteries 171 and a stabilizing 
circuit 172 for rectifying and supplying power for the main frame 1. The 
portable controller 2 is also powered by a power source 24 for maintaining 
the functions thereof. The power source 24 includes several batteries 241 
and a stabilizing circuit 242 for rectifying and supplying power for the 
portable controller 2. 
According to the above arrangement, the car location indicating and 
burglarproof alarm device of the present invention can achieve double 
effects in a simple pattern. Therefore, the shortcomings of the 
conventional car-used burglarproof alarm and location indicating device, 
that is, complicated wires must be embedded in the car and a drilling 
operation is necessitated are eliminated. 
The above embodiment is only used to illustrate the present invention, not 
intended to limit the scope thereof. Many modifications of the above 
embodiment can be made without departing from the spirit of the present 
invention.
