The function of the emergency opening button 20 of the electronic cargo box lid is to input the signal of emergency opening of the cargo box lid to the control device 120 when the person trapped in the cargo box presses it. As shown in Figure 7, it is designed to be exposed so that a person trapped in the cargo box can press the striker 56 as it is raised.

The role of the firing pin raising button 32 and the firing pin lowering button 34 on the firing pin control button 30 is to input a firing pin raising signal or a firing pin lowering signal to the control device 120, so as to lift or lower the firing pin 56 to a predetermined level, as shown in Figures 3 and 4 As shown, because they are mounted on the front surface of the striker assembly 50, they can be depressed by a person trapped in the cargo box.

At this time, the buttons 20, 32 and 34 are specifically arranged to actuate when they are only actuated by a person, so as to prevent them from being actuated by being pressed by items stored in the cargo box.

The second anthropometric device 66 includes a high-frequency oscillator 67 that oscillates at a high frequency such as 1 megahertz, and a high-frequency receiver 68 for receiving the high frequency oscillated by the high-frequency oscillator 67, thereby according to the The principle that the high-frequency level accepted by the frequency receiver 68 can change due to the approach of people can identify whether people are trapped in the cargo box.

That is, when a human body approaches, the high-frequency level increases, and when the person moves away, the high-frequency level decreases. Through this phenomenon, the person trapped in the cargo box is detected.

The theft measuring device 75 identifies whether the car is stolen, and can be realized by a device for measuring car theft installed on the car, so as to prevent theft.

That is to say, when the door of the car is not opened by predetermined remote control manipulation, but is forced to open, the theft detection device 75 can measure this situation, thereby preventing from being stolen.

Moreover, the impact measuring device 85 is used to measure the impact caused by the collision or accidental fall of the vehicle, and its function is realized by a sensor for measuring the impact, which triggers a life-saving air bag installed on the vehicle.

The function of the bolt assembly 40 is, as shown in FIGS. 3 and 4 , when the emergency opening button 35 of the mechanical cargo box lid is pressed down, or when the electromagnetic coil 126 is triggered by the control of the control device 120 , the firing pin 56 of the firing pin assembly 50 is activated. Go up and throw off bolt 47, so that container cover is opened urgently. Once the button 35 is depressed, or the solenoid 126 acts to disengage the bolt from the striker 56 , the bolt 47 is no longer coupled to the striker 56 .

As shown in Figures 3, 4 and 5, in the bolt assembly 40, when the button 35 is depressed, or the electromagnetic coil 126 is activated, the push rod 41 is disengaged from the bolt clutch lever 42, and it touches the clutch by the elasticity of the spring 43. The lever 44 thereby rotates the locking pin 49 . The latch 45 is then disengaged from the latch retainer 46 such that the bolt 47 is separated from the striker 56 .

A spring pin 48 is provided in the latch retainer 46 so that when the latch 45 is disengaged from the latch retainer 46, the latch 45 cannot be reinserted into the latch retainer 46, thereby preventing the cargo lid from closing.

At the same time, as shown in Figures 6 and 7, the role of the striker assembly 50 is to move the striker 56 vertically to a predetermined level according to the control of the control device 120. The assembly 50 includes a motor that drives the striker 56; the rotation of the motor 52 is converted A transmission 54 for transmitting the movement vertically; and a striker 56 for receiving power from the transmission 54 to move vertically.

When a signal indicating that the lid is closed is input from the lid opening determination button 10, the control means 120 operates the display means 90 at a predetermined time.

Moreover, when the cargo lid close signal and the anthropometric measurement signal are simultaneously input, or the button 32 or button 34 is pressed, the control device 120 maintains the operation of the display device 90 and controls the speaker control device 100 so that the speaker does not work.

The control device 120 also controls the transceiver 110 to broadcast the occurrence information of the unexpected event to a predetermined terminal device. After receiving a signal indicating that the container lid is closed from the container lid opening measurement button 10, and identifying someone from the human body measuring device 60, when the person is trapped in the container for more than a predetermined time, or due to human Trapped in the cargo box, when the button 32 or button 34 is kept depressed for a time greater than a predetermined time, the control device 120 makes the electromagnetic coil 126 work, and the bolt 47 on the bolt assembly 40 is disengaged from the striker 56 of the striker assembly 50 , thereby opening the cargo compartment lid in an emergency.

Moreover, when the bolt 47 is disengaged from the striker 56 to open the cargo lid, the control device 120 controls the speed control device 70 and the emergency alarm device 80 respectively to limit the speed of the vehicle to be less than a predetermined reference speed and generate an emergency alarm simultaneously.

When the button 32 is depressed so that the striker up signal is input, the control device 120 reversely rotates the motor 52 to lift the striker 56 to a predetermined height. When the button 34 is depressed to receive the striker lowering signal, the control device 120 reversely rotates the motor 53 to lower the striker 56 .

When the theft measurement signal and impact measurement signal are received by the theft measurement device 75 and the impact measurement device 85, or when the container cover closing signal and the human body measurement signal are input simultaneously, the control device 120 controls the transceiver 110 to propagate an accident to a predetermined terminal device. information about the occurrence of the event.

Furthermore, when the impact measurement signal and the emergency alarm signal are received, or when the container lid closing signal and the human body measurement signal are simultaneously input, the control device 120 moves the electromagnetic coil 126 to open the container lid, and operates the speed control device 70. Work with the emergency alarm device 80, limit the running speed of the car to be less than a predetermined speed, and generate an emergency alarm.

Simultaneously, Fig. 8 is the circuit diagram of the emergency opening device of the automobile cargo box lid according to the first embodiment of the present invention. When the buttons 32 and 34 are pressed by the person trapped in the cargo box, the striker up/down switches S2 and S3 are respectively invalid; when the button 20 is pressed by the person in the cargo box, the emergency opening switch S4 of the cargo box lid is disconnected ; Light P1 is used to indicate whether the cargo lid is opened or closed when the cargo lid is opened, and is located on the dashboard of the driver's seat; and, light-emitting diodes LED1, LED2, LED3 and light P2 are used to indicate The positions of the buttons 20, 32 and 34, which illuminate the interior of the cargo box, correspond accordingly to the display unit 90.

The control device 120 has a plurality of resistors R1-R23, a plurality of capacitors C1-C13, a plurality of transistors TR1-TR11, a diode D1, a plurality of logic gates AND1-AND6, a plurality of logic "OR" gates (logical sum gate) OR1-OR9, a relay RL1, an inverter INV1, a plurality of flip flops F1-F5, a voltage regulator 121, a plurality of timer circuits 122-125, an electromagnetic coil 126 and an overcurrent measuring device 127, respectively used to control: human body measuring device 60, theft measuring device 75, impact measuring device 85, container lid opening measuring switch S1, striker up/down switch S2 and S3, bolt assembly 40, striker assembly 50, speed Control device 70 , emergency alarm device 80 , display device 90 , speaker control device 100 and transceiver 110 .

FIG. 9 is a circuit diagram of an automobile trunk lid opening device according to a second embodiment of the present invention, which is almost the same as that of the first embodiment in FIG. 8 . The only difference is that in the first embodiment, the triggers F1, F2 and F3 and the overcurrent measuring device 127 are used to drive the striker drive motor 52, while in the second embodiment the switch S5 is used.

That is, when the switch S5 raised and lowered together with the striker 56 is fully raised, current is supplied to the motor 52 to lower the striker 56 , and when the switch S5 is fully lowered, current is supplied to the motor 52 to lift the striker 56 .

Now, the operation effect of the emergency opening device for the trunk lid of the present invention constituted in this way will be described in detail.

As shown in FIG. 10 , when the cargo lid 1 is closed, the bolt 47 on the bolt assembly 40 is fixed to the striker 56 , as shown in FIG. 11 , to keep the cargo lid 1 closed.

As shown in Figure 12, when the cargo box lid 1 is closed, when the striker 56 on the striker assembly 50 is opened by the cargo box lid opening manipulator on the side of the driver's seat, or when it is opened by the car key, the cargo box Cover 1 is open.

At this time, when the person trapped in the cargo box presses the emergency opening button 35 of the mechanical cover, or the electromagnetic coil 126 is controlled by the control device 120, the bolt assembly 40 will disengage the bolt 47 from the striker 56, thereby opening the cargo box urgently. Cover 1.

That is, the push rod 41 is disengaged from the bolt rod 42 , and the bolt clutch lever 42 is elastically acted by the spring 43 and touches the clutch lever 44 .

Consecutively, if the trip lever 44 is raised upwards, the locking pin 49 rotates and the latch 45 disengages from the latch retainer 46 so that the striker 56 disengages the bolt 47 .

At this time, as shown in FIG. 5, because the spring pin 48 is contained in the latch holder 46, when the latch 45 is disengaged from the latch holder 46, the latch holder 46 is not inserted therein, preventing the container The cover is closed.

When it is necessary to repair the hitch assembly 40 thus disassembled, there is a problem that the cargo box inner lid must be removed and a pin hole must be drilled, so field repairs are difficult and the vehicle needs to be sent to a repair shop.

Therefore, when the cargo lid 1 is opened with the cargo lid opening manipulator or the car key, the cargo lid can be closed again, and when the person trapped in the cargo box presses the mechanical button 35, or the electromagnetic coil 126 is controlled When the control of the device 120 triggers the emergency opening of the cargo box lid 1, the cargo box lid 1 cannot be closed again.

And as shown in Figures 6 and 7, in the striker assembly, when the motor 52 rotates forward, the rotation shaft 54-1 also rotates forward to lift the feed rod 54-2 and lift the feed rod 54-2 The striker 56 moving together, as shown in FIG. 14 , enables the cargo box cover 1 to be lifted to a predetermined height, thereby allowing people trapped in the cargo box to peek outside.

Also, when the motor is reversed, the rotary shaft 54-1 is reversed to lower the feed rod 54-2, and at the same time the striker 56 is lowered, thereby closing the cargo lid 1.

Referring now to Fig. 8, the working process of the emergency opening device for the trunk lid of the automobile according to the first embodiment of the present invention will be described.

The battery voltage (B+) (for example, 12V) is applied to the electrostatic voltage regulator 121 via capacitors C1 and C2, which transforms the battery voltage (B+) into a predetermined voltage (Vcc) (for example, 9V) for starting the control device 120, via the capacitor C3 and C4 supply power.

When the cargo lid 1 is closed, the cargo lid opening detection switch S1 is ineffective, and the battery voltage (B+) is divided by the resistors R2 and R3 to be input to the first logic gate AND1.

Within the predetermined time (such as 10 seconds) determined by the charging/discharging constant of the capacitor C5 and the resistor R4, the high-level voltage signal is output from the first logic gate AND1 and input to the second, third and fourth logic gates AND2, AND3 and AND4, and input to the first logical OR gate OR1.

Successively, the first OR gate OR1 outputs a high-voltage signal to the base terminal of the first transistor TR1 to turn on the first transistor TR1, thereby, the battery voltage (B+) is added to the lamp P2 and the light-emitting diodes LED1, LED2, and LED3 of the display device 90 , so that the lamp P2 and the diodes LED1, LED2, and LED3 emit light.

That is, when the cargo box lid 1 is closed, the interior of the cargo box is illuminated for a predetermined time, such as 10 seconds, so that people trapped in the cargo box can recognize the positions of the buttons 20, 32 and 34.

Simultaneously, in the state where the high-level voltage signal is generated from AND1, when the button 32 is pressed down by the person trapped in the cargo box, the striker lift switch S2 is invalid, and a high voltage is input to the second logic "OR" gate OR2. A flat voltage signal, and then output a high-level voltage signal.

Then, within a predetermined time determined by the charge/discharge constant of capacitor C9 and resistor R12, a high-level voltage signal is input to the collector S of the first flip-flop (F1), and the first flip-flop (F1) outputs via non-inverting The terminal (non-inversion) Q continuously outputs a high-level voltage signal to the fifth logic AND gate AND5. Logical multiplication is performed on the high-level voltage signal output from the non-inverting output terminal Q and another high-level voltage signal output from the second AND2, and a high-level voltage signal is output to the second transistor T2 and the fourth transistor T2 Base of transistor T4.

Subsequently, the third transistor TR3 and the fifth transistor T5 are turned on to rotate the motor 52 forward and lift the striker 56 .

That is, when the striker up switch S2 is turned off, a high-level voltage signal is generated from the fifth AND5 and turned to the second, third, fourth and fifth transistors T2, T3, T4 and T5. The motor 52 is then applied an electrostatic voltage for raising and lowering the striker 56 to rotate the motor in the forward direction. The striker 56 is then lifted.

Simultaneously, when container lid 1 is closed and makes AND1 output high-level voltage signal, the striker drop button is depressed by the people trapped in the container, disconnects striker drop switch S3, and high-level voltage signal is input to AND3, and it again Output a high-level voltage signal.

When the high-level voltage signal is output from AND3, the high-level voltage signal is input to the collector terminal S on the second flip-flop (F2) within the predetermined time determined by the discharge/charge constant of the capacitors C10 and R13, and the high-level voltage signal A flat continuous voltage signal is output from the non-inverting output terminal (Q) of the second flip-flop (F2) to the sixth logic gate AND6.

The voltage signal output by the non-inverting output terminal (Q) and the voltage signal output from the third logic gate AND3 are logically multiplied on the sixth logic gate AND6, and then output to the base terminals of the sixth and eighth transistors T6 and T8 .

Successively, when the cargo box lid is closed and the striker drop button 34 is pressed down to disconnect the striker drop switch S3, a high-level voltage signal is output from the sixth logic gate to open the sixth, seventh, eighth and ninth gates. Transistors T6-T9. A reverse voltage is applied to the motor 52 for raising and lowering the striker 56 so that it rotates in reverse and the striker 56 is lowered.

When the motor 52 is fully lifted or lowered to allow the overcurrent to flow, the overcurrent measuring device 127 detects this phenomenon, sets a reset signal to the reset terminal R on the flip-flops F1 and F2, and resets the flip-flops F1 and F2. The power supply of the motor 52 is then cut off, and the striker 56 is stopped.

Simultaneously, when the people trapped in the cargo box keeps pressing the button 34 outside the preset time (enough time for the striker 56 to fully descend) in a panic, that is, the striker lowering switch S3 is charged/discharged at the predetermined time determined by the resistor R11 and the capacitor C8 charge/discharge constant. When disconnecting outside the time, a high-level voltage signal is input to the second logic "OR" gate OR2, which outputs a high-level voltage signal again, thereby lifting the striker 56. Therefore, the striker 56 is automatically raised.

And, the main sensor 62 for measuring people or the auxiliary sensor 64 for measuring people measure the infrared rays emitted from the human body trapped in the cargo box, and send it to the amplifying device 64, which amplifies the signals output from the sensors 62 and 64, and It is sent to authentication means 65 . The discriminating device 65 accepts the signal output from the amplifying device 64, if it distinguishes that someone is trapped in the cargo box, it will send a high-level electric signal to the fourth logic gate AND4.

Because the high-frequency level accepted by the high-frequency receiver 68 changes with the proximity of the human body, it can be determined whether people are trapped in the cargo box by the high-frequency level change accepted on the high-frequency receiver 68 . If it is identified that someone is trapped in the cargo box, the second body measuring device 66 outputs a high-level voltage signal to the fourth logic gate AND4.

In the state where the cargo lid is closed so as to receive a high-level voltage signal from the first logic gate AND1, when a high-level voltage signal is input from the human body measuring device 60, the fourth logic gate AND4 sends a signal to the first timer Circuit 122 outputs a high-level voltage signal.

When a high-level voltage signal is input from the fourth logic gate AND4 outside the predetermined time (for example, 2 seconds), the first timer circuit 122 outputs a high-level voltage signal to the fourth logic OR gate OR4 again, and according to The triggering or deactivation of the striker up switch S2 or the striker down switch S3 is performed on the third logic OR gate OR3, and the logic sum of the input voltage signals is output to the fourth logic OR gate OR4.

On the fourth logic "OR" gate OR4, the high-level voltage signal output from the first timer circuit 122 and the voltage signal output from the third logic "OR" gate OR3 are logically summed and sent to the third flip-flop Collector S output of F3.

When a high-level voltage signal is input from the fourth logic "OR" gate OR4, until a reset signal is input, the third flip-flop F3 keeps inputting a high-level voltage signal to the first logic "OR" gate OR1 for to drive the display device 90 . At the same time, the third flip-flop F3 inputs a high-level voltage signal to the speaker control device 100, stops the operation of the speaker 102, and inputs a high-level voltage signal to the transceiver 110 through the ninth logic "OR" gate OR9, so that the transceiver 100 broadcasts a message that an unexpected event has occurred to predetermined terminal devices.

That is, when the high-level voltage signal of the third flip-flop F3 is input to the base terminal of the eleventh transistor T11 , the eleventh transistor T11 operates to turn off the relay RL1 and subsequently also turn off the speaker 102 .

Successively, when the anthropometric device 60 detects a person trapped in the cargo box under the closed situation of the cargo box lid, or when a person in the cargo box presses the striker up and down button 32, the inside of the cargo box is illuminated, and simultaneously the button The positions of 20, 32 and 34 are visible to those trapped in the cargo box. The inoperative speaker in the car makes it easy to make an emergency call, the transceiver 110 activates, and makes an accident understandable via a predetermined terminal device.

At this time, the ninth logic "OR" gate OR9 performs a logical sum on the output signal of the third flip-flop F3, the output signal of the theft detection device 75 and the output signal of the shock detection device 85, and outputs the result.

Successively, when the theft measuring device 75 detects that the car is stolen, a high-level theft detection signal is output, or when a collision is detected, a car falls accidentally, etc., a high-level impact measurement signal is output, from the ninth Logic "OR" gate OR9 generates a high level voltage signal, which triggers transceiver 110, so that the occurrence of unexpected events can be known via predetermined terminal devices.

Moreover, the output signal of the third flip-flop F3 is input to the second timer circuit 123, and when a high-level voltage signal is output from the third flip-flop F3 outside a predetermined time (such as 3 minutes), it sends a signal to the fifth logic "OR" again. The "gate OR5 outputs a high-level voltage signal. Here, when a high-level voltage signal is input from the third logic "OR" gate OR3, the second timer circuit 123 is reset again.

Then, when a high-level voltage signal is output from the third logic "OR" gate OR3 outside the predetermined time (such as 20-30 seconds), the third timer circuit 124 outputs a high voltage to the fifth logic "OR" gate OR5 Level signal, here, on the fifth logic "OR" gate OR5, the signals output by the second timer circuit 123 and the third timer circuit 124 are logically ORed, and then output to the collector terminal of the fourth flip-flop F4 S.

When a high-level voltage signal is input from the fifth logic "OR" gate OR5, the fourth flip-flop F4 outputs a high-level voltage signal to the seventh logic "OR" gate OR7 through the non-inverting terminal Q.

Thus, the electromagnetic coil 126 is triggered, so that the bolt 47 on the bolt assembly 40 is disengaged from the striker 56 on the striker assembly 50 , so that the cargo box cover 1 is opened.

And when the high-level voltage signal was output from the seventh logic "OR" gate OR7, the speed control device 70 and the emergency alarm device 80 started to work, so that the speed of the car was limited to a predetermined speed (such as reaching the car trapped in the container). The speed at which people can easily escape), and at the same time carry out emergency alarm work.

At this time, if the voltage signal input from the ON/OFF state of the electronic cargo lid emergency opening switch S4 is input on the seventh logic OR gate OR7 to the signal output from the fourth flip-flop F4 via the non-inverting terminal Q, the impact The output signal of the measuring device 85 and the output signal of the transceiver 110 are logically ORed, even if there is a high-level impact measurement signal output from the impact measuring device 85, or a high-level emergency alarm signal is output from the transceiver 110, the tenth Transistor T10 is turned on. As a result, the electromagnetic coil 126 is activated, the bolt 47 is separated from the striker 56, and the cargo box lid 1 is opened. Then, make the speed control device 70 and the emergency alarm device 80 work, limit the speed of the car to a predetermined speed (as the speed at which people trapped in the cargo box can easily escape), and perform emergency alarm work simultaneously.

Moreover, when the high-frequency voltage signal keeps entering from the seventh logic "OR" gate OR7 outside the predetermined time, the fourth timer circuit 125 outputs a high-level voltage signal to the eighth logic "OR" gate. When the battery is changed and a reset signal is input to reset the reset terminals R of the third and fourth flip-flops F3 and F4, the high-level voltage output by the fourth timer circuit 125 is performed on the eighth logic OR gate OR8 The logical sum of the signal and the high-level voltage signal input by the capacitor C12 and the resistor R22, so that the electromagnetic coil 126, the speed control device 70 and the emergency alarm device 80 will not stop for a predetermined time after the emergency opening of the cargo box cover 1 or within the battery replacement time. Work.

Then, a high-level voltage signal is input to the collector terminal S of the fifth flip-flop F5 when changing the battery, and the fifth flip-flop F5 inputs a high voltage signal to the sixth logic "OR" gate OR5 when changing the battery. The level voltage signal keeps the striker 56 in the downward state automatically.

Simultaneously, in the emergency opening device of the automobile cargo box lid of the second embodiment of the present invention shown in FIG. When the person in the box presses the button 32 and turns off the switch S2, the high-level voltage signal is input to the second logic "OR" gate OR2, causing the high-level voltage signal to be output from the second logic gate AND2.

As described above, when the high-level voltage signal is output from the second logic gate AND2, the second, third, fourth and fifth transistors are operated, and a static voltage is applied to the motor 52 for raising and lowering the striker , forward rotation motor 52, so the striker rises.

At this time, when the striker 56 is fully lifted, the switch S5 connects the A terminal to the B terminal, thereby cutting off the current supplied to the motor 52 through the diode D3, so that the motor stops working.

Simultaneously, under the state that the first logic gate AND1 outputs the high-level voltage signal when the lid of the cargo box is closed, when the person trapped in the cargo box presses the button 34 to close the switch S3, the high-level voltage signal is sent to the third logic gate. The gate AND3 is input, and a high-level voltage signal is output from the third logic gate.

When the high-level voltage signal is output from the third logic gate AND3, as described above, the sixth, seventh, eighth and ninth transistors T6, T7, T8 and T9 start to work, and a reverse voltage is applied to the boost and Lower the striker 56 on the motor. The striker drive motor 52 rotates in reverse to lower the striker 56 .

At this time, when the striker 56 is fully lowered, the switch S5 connects the B terminal to the C terminal, thereby cutting off the current supplied to the motor 52 . Motor 52 stops working.

That is, when the switch S5 , which is raised and lowered together with the striker 56 , is fully raised, current is supplied to the motor 52 to lower the striker 56 . When the switch S5 is fully lowered, current is supplied to the motor 52 to lift the striker 56 .

It is evident from the above description that the emergency opening device for the trunk lid of a car according to the present invention has the following advantages, that is, the kidnapped person who is trapped in the trunk of the car with his hands and feet can escape, because the trunk lid opens at a predetermined time. Automatically open later.

Another advantage is that the interior of the cargo box is illuminated by the built-in anthropometric device, and the person trapped in the box can see the positions of the various buttons, so that when the firing pin up button is depressed, the firing pin is lifted to raise the cargo box cover. Up to 50 mm to provide the occupant of the cargo box with a gap through which he or she can peek out and call for help.

Another advantage is that when it is identified that the person trapped in the cargo box can escape, the emergency opening button of the cargo box lid is pressed, which limits the speed of the car in which the person is trapped, and makes the emergency alarm device work, so that the surrounding people can be notified of the accident. Cars are vehicles used by criminals.

Another advantage is that once the cargo lid emergency release button is actuated, the latch assembly disintegrates so that the cargo lid can no longer be closed, so as to pre-empt crimes involving the cargo box of a car, and people trapped in the cargo box can easily get out of it. escape.

Another advantage is that when unexpected events such as car theft, collision, and kidnapping of missing persons occur, the information can be transmitted to a predetermined terminal, so that others know that someone is in trouble. It can transmit an emergency alarm signal to the car, open the cargo box cover urgently, and generate an emergency alarm sound, so that the car in trouble can be tracked.
