[0001] The present invention relates to the technical field of reminder device, more particularly, to an article reminder before leaving vehicle. BACKGROUND

[0002] Car is an important means of transportation in life, people often forget to take luggage when leaving the car. Hong Kong has a "road things can not be lost" telephone hotline, providing passengers to find lost property. But this is limited to the honest taxi driver or follow the honest passengers get on the bus. Believed that most of the lost property is taken by the next dishonest passenger get on the bus. News reports that in London, England, about 10,000 mobile phones, 1,000 laptops are left in the taxi every month. The report did not mention other lost property, and did not mention the number of dishonest people taking such property. In fact, this situation is not possible in other cities. Ordinary private cars also have similar problems, often have to return to the parking lot to take back the things that have been taken away, which is not only troublesome, but also wastes time.

[0003] Therefore, relying on the honesty and memory of people to avoid the risk of uncertainty is too large, and people always have lapses, so it is necessary to take scientific means to avoid such situations, such as an instrument to remedy the troubles and losses caused by the shortcomings of the human brain will meet the expectations of the public. SUMMARY

[0004] In order to solve or alleviate the problem that people often forget to take luggage when leaving the car in the prior art, the present invention provides an article reminder before leaving the vehicle, which is a low-cost and safe reminder device installed on the car, the purpose is to remind the passengers to check and take all the things that should be taken but may still be left in the car before leaving the car. The present invention has strong practicability, relatively low cost, and the whole reminder device is waterproof and will not cause explosion of flammable gas that may exist around.

[0005] The technical solution of the present invention is as follows:

[0006] The article reminder before leaving the vehicle is installed on the car, including a first switch assembly, a second switch assembly and a reminder main body, the reminder main body can be installed on the door of the car compartment or any convenient position for installation and use, such as installing the reminder main body under the door of the side seat under the car compartment, which can protect the passengers from being injured by side impact traffic accidents.

[0007] The first and second electric switch boxes can be permanent magnet electric switch boxes or electric switch boxes. The first switch assembly includes a permanent magnet carrier fixed to the back of the door handle of the vehicle cabin and a first electric switch box fixed below it, and the second switch assembly includes a second electric switch box installed near the side of the vehicle door and a permanent magnet strong magnet on or below the door frame or on the floor of the vehicle cabin. The back of the main body of the prompter has a positioning and selection function, and the second electric switch box can be fixed there. In this way, the prompter body can be installed close to the floor of the vehicle cabin to cooperate with the permanent magnet strong magnet installed on the floor of the vehicle cabin to stop the prompt sound. The outside of the prompter body is provided with a second accommodation groove, a main switch, a sound box and a stop button combination for controlling the sound of the sound box. The prompter body is covered by a safety shield. The first and second electric switch boxes can be covered with a round edge protective cover, and the connection wires long enough can be installed on various types of vehicles. The excess connection wires can be wound in a wire storage reel, and the reel cover is covered with a round edge. A pair of symmetrical ear positions and a pair of symmetrical notch positions are provided in the center of the round hole, and the wire storage reel and the reel cover combination can be fixed to the door by screwing through the round hole. The notch position allows the incoming and outgoing connection wires to pass through. Or cut off the excess wire of the connection wire, then weld the wire, and then wrap it with insulating tape. The wrapped tape is preferably pushed into the position between the back of the prompter body and the door to achieve a more beautiful effect.

[0008] The prompter body is provided with a second accommodation groove, which includes a battery compartment for placing a battery and a circuit board compartment for placing a circuit board. The battery compartment and the circuit board compartment are respectively located on the front and back of the prompter. The battery compartment is on the front of the second accommodation groove body, and the circuit board compartment is recessed in the battery compartment. The circuit board is loaded from the circuit board compartment on the back of the prompter body. The circuit board has six connection wires, the first connection wire is connected to the fourth electric switch box of the main switch, the second connection wire is connected to the first electric switch box, the third connection wire is connected to the second electric switch box, the fourth connection wire is connected to the speaker of the sound box, the fifth connection wire is connected to the third electric switch box of the stop button combination, and the sixth connection wire is connected to the pole of the battery compartment through the small hole in the bottom plate of the battery compartment. The small hole in the bottom plate of the battery compartment has a wall around it to facilitate sealing the gap between the wire and the small hole with glue, which prevents water from entering the battery compartment from the bottom of the prompter body. Two 1.5V batteries can be placed in the battery compartment, and the battery cover can prevent the batteries from sliding out.

[0009] The triangular symbol between the screw hole and the sound box frame in the lower right corner of the prompter body. When you want to cover the battery cover, you need to align the "open lock symbol" on the battery cover with the sharp corners of the triangular symbol, then push the cover down, and then rotate the cover clockwise until the other symbol on the battery cover aligns with the sharp corners of the triangular symbol, indicating that the cover is tightly screwed. This is to facilitate mass production, and its effect is the same as that of the ordinary rotating cover to the end, which can prevent water from entering; To open the cover, simply rotate the cover counterclockwise.

[0010] The prompter body is provided with a stop sound button combination, which includes a first accommodating slot on the prompter body, and a square opening for accommodating a square body stop sound button on the top of the first accommodating slot, which can move up and down to provide the function of stopping the prompt sound. The stop sound button body is provided with the mounting slot near the side of the groove, and the third magnetic attraction piece is embedded in the mounting slot. The third magnetic attraction piece is a strong magnet with a small magnet, and the bottom of the stop sound button is provided with a limiting column. A spring is sleeved on the limiting column, which is aligned against the limiting column. The bottom of the spring is provided with a supporting bottom plate for supporting the spring, and the supporting bottom plate is provided with a buckle at four corners for fixing to the back of the prompter body. A groove is provided near the side of the square opening, and part of the third electric switch box is embedded in the groove. The spring abuts against the stop sound button, so that the third magnetic attraction piece is always aligned with the third electric switch box, forming a normally closed switch made of a permanent magnet magnetic force. The stop sound button is in the first position to conduct the circuit. Pressing the stop sound button makes the third magnetic attraction piece away from the third electric switch box. When the stop sound button is pressed to the end, the reed switch of the third electric switch box is out of the magnetic force range and does not pass electricity. The stop sound button is in the second position to disconnect the circuit, so that the prompt sound stops immediately. When the stop sound button is not pressed, the spring can make the stop sound button pop up and restore the circuit of the prompter. The next time the door handle is pulled down, the prompt sound will start again. Pressing the stop sound button can only stop the prompt sound, but cannot turn off the prompter.

[0011] The stop sound button is surrounded by a roof to limit its movement space. The four corners of the square opening are two pairs of corners with different radii. The side of the supporting bottom plate has a fence that can prevent fingers or foreign objects from pushing away the spring. The fence also allows air to circulate in the space, making it easy to drain and evaporate water. The accumulated dust and sand can also be washed away with water.

[0012] The sound producing assembly comprises a sound producing box and a loudspeaker installed in the sound producing box. The circumference of the loudspeaker is surrounded by industrial glue liquid to connect the inner wall of the sound producing box without leaving any gap. The bottom of the sound producing box has a small hole through which the electric wire welded to the loudspeaker passes. The gap between the electric wire and the hole is sealed by industrial glue liquid. Thus, water cannot enter the back of the loudspeaker from the bottom of the prompter main body and the front of the loudspeaker, so that a low-specification back non-waterproof loudspeaker can be used. The frame of the sound producing box has a screw-in position, which allows the sound producing box cover with a mesh sound hole to be tightly fixed in a normal screwing manner. The sound producing box cover also allows the user to unscrew the sound producing box to clean the accumulated dust. The method of closing and opening the sound producing box cover is the same as that of closing and opening the battery cover.

[0013] The total electric switch comprises a total electric switch bottom plate, a total electric switch upper cover, a fourth electric switch box, an electric switch push button and a spring buckle temporarily locking the electric switch push button in the on or off position. The electric switch box is placed in the total electric switch bottom plate. The electric switch push button comprises an electric switch push button body and a strong permanent magnet hidden in the center of the bottom of the electric switch push button body. The small magnet is fixed by glue liquid. The total electric switch upper cover has an open track for the electric switch push button to be pushed.

[0014] The prompter main body is also covered by a safety shield. The safety shield has a recess above the mute button, and the recess has a through hole in the center to match the circumference of the mute button to allow the mute button to pass through and move smoothly up and down. When the safety shield is closed, the top of the mute button is flush with the top of the safety shield. The safety shield has four corners, each with a curved downward part with an inclined and slidable buckle position to be buckled to the bottom of the prompter main body. Only by pulling the lower edge of one of the short sides of the safety shield can the safety shield be opened. Four rectangular holes near the four corners of the safety shield are used for plastic mold manufacturing buckle connection. The four rectangular holes can be sealed with additional accessories. The safety shield is provided with enough sound holes to facilitate the transmission of sound.

[0015] The above-mentioned article reminder before leaving the vehicle can also be arranged on a taximeter vehicle with a driver button for opening and closing the door. The article reminder before leaving the vehicle further comprises a switch control device, which comprises a main sound box, an electric switch, a normally open switch and a normally closed switch. The main sound box has two groups of electric wires. The first group of electric wires is led out from the circuit of the main sound box to the electric switch and the normally open switch, which are connected simultaneously with the starting of the taximeter and the opening of the door by the driver button, so that the reminder sounds. The electric switch and the normally open switch are connected in series. The second group of electric wires is led out to the normally closed switch, which is pressed simultaneously with the closing of the door by the driver button to stop the reminder from sounding. Since the dry reed tube in the electric switch box is controlled by a permanent magnet, the explosion of the possible flammable gas is avoided. In another design, the normally open switch and the normally closed switch can be arranged in two boxes with screw caps, respectively. A button is fixed on the top of the shaft of each box to connect to the two boxes to press the normally open switch and the normally closed switch, respectively. The spark generated by pressing the buttons of the normally open switch and the normally closed switch will not cause the explosion of the possible flammable gas outside the boxes.

[0016] The article reminder before leaving the vehicle is a low-cost and safe reminder sounding device arranged on a vehicle, which reminds the passengers to check and take all the things before leaving the vehicle, so as to avoid the loss of the things left in the vehicle or the trouble and time waste caused by returning to the parking place to take the things left in the vehicle. The article reminder before leaving the vehicle has strong practicability, relatively low cost, waterproof and no explosion of the possible flammable gas around. BRIEF DESCRIPTION OF DRAWINGS

[0072] The following will introduce four preferred embodiments of the present application, which respectively adopt two basic circuits. Embodiment 1

[0073] As shown in Fig. 45, the present embodiment adopts a magnetic induction opening door sound device circuit, as shown in Fig. 1 and Fig. 2, which is the standard position of each part of the prompting device installed on the car door 39. In Fig. 1, the prompting device body 1 is installed on the door of the front seat in the car cabin and is covered with a safety shield 10, other parts include the permanent magnet magnet carrier 33 which is fixedly attached to the back of the opening door handle 38 in the car cabin, the first electric switch box covered with the shroud 20, namely the electric switch box and shroud combination 2, the first electric switch box is the permanent magnet magnet electric switch box 22, and the second electric switch box installed on the car door 39 in the car cabin close to the car floor 36 with the scale line on one side aligned with the second permanent magnet strong magnet 333 installed on the car floor 36, and an electric wire storage reel and reel cover combination 8. The prompting device body 1 installed on the car door 39 of the rear seat is not covered with a safety shield 10 in order to mark the parts, and the second electric switch box is fixedly attached to the back bottom of the prompting device body 1, so as to cooperate with the permanent magnet strong magnet 333 on the car floor 36 to stop the prompting sound.

[0074] As shown in Fig. 3, Fig. 5, Fig. 6, the permanent magnet carrier 33 has a scale line symmetrically dividing its hypotenuse from top to bottom, it is preferably installed on the back of the door handle 38 in the carriage, about 10 mm away from the end, the part is to be rubbed with the coarsest sandpaper to be rough, so as to stick the permanent magnet carrier 33 with slow-drying mixed glue or other appropriate adhesive, before falling the glue, take a business card and cut it into two equal parts with scissors and neatly stack together, wrap the two business cards with double-sided adhesive tape without wrinkles, put the business card into the small niche under the door handle 38 (Fig. 41, step 1), the best adhesive is "magic steel glue", if slow-drying mixed glue is used, the two business cards must be completely wrapped with double-sided adhesive tape, the surface of the business card facing up is to be stuck with a thin film, then put the business card into the niche under the door handle 38, so that the side with adhesive force sticks the business card in the niche, then falls the glue and sticks the permanent magnet carrier 33 on the back of the door handle 38, perhaps more glue is needed on the back of the permanent magnet carrier 33 to keep the permanent magnet facing down, then wrap the permanent magnet carrier 33 with adhesive tape around the door handle 38, take out the waste paper ball, do not move the business card when getting off the car with the door 39, wait for about eight hours before tearing off the adhesive tape and moving away the business card; the permanent magnet carrier 33 includes a permanent magnet carrier 331 that holds and sticks with glue a first permanent magnet 332 with a diameter of 5 mm and a thickness of 3 mm, the first and second electric switch boxes have scale lines located 1 mm away from each end of the box. The permanent magnet electric switch box 22 includes a permanent magnet electric switch box 22 body with permanent magnet positioning grids, and a third magnetic member 162 is stuck with glue in the grid on one side of the box, the magnetic members are all permanent magnet strong magnets. If the permanent magnet electric switch box 22 is to be installed below the door handle 38, it must be aligned within 10 mm of one of the scale lines to the edge of the adhesive tape that crosses the scale line of the permanent magnet carrier 33 above it (Fig. 41, step 3), a lateral deviation of no more than 3 mm is effective for installation; then use a waste paper ball to push against the door handle 38 in the open state, and then use a strip of adhesive tape to align one of the scale lines with the scale line of the permanent magnet carrier 33 (Fig. 41, step 2), the strip of adhesive tape can be wrapped around the door handle 38 together with the permanent magnet carrier 33, remove the waste paper ball, when installing the permanent magnet electric switch box 22, test to find out which of the two scale lines is the one that is to be aligned with the edge of the adhesive tape above it; the third magnetic member 162 can make the reed switch 212 of the permanent magnet electric switch box 22 constantly internally connected.

[0075] The second electric switch box is fixedly installed on the side of the door 39 or below the door 39 close to the floor 36 of the carriage. If it is installed close to the floor 36 of the carriage, the second permanent magnet strong magnet 333 with a diameter of 6 / 6.3 mm and a thickness of 3 mm installed on the floor 36 of the carriage must be installed in the middle of one of the scale lines of the second electric switch box and be aligned below the second electric switch box within a range of 10 mm. If the second electric switch box is installed on the side of the door 39, the second permanent magnet strong magnet 333 installed on the frame of the door 39 must be aligned with one of the scale lines of the second electric switch box and the maximum distance cannot exceed 10 mm, and the deviation cannot exceed 3 mm, which are effective installations.

[0076] The circuit of the embodiment has a feature that two circuit positions in the circuit can hide the prompt sound of the loudspeaker 121 when connected. In fact, the prompt signal continues to run in the circuit until the end of the section of the cut signal. When the prompt signal runs in the circuit, disconnecting the two circuit positions can make the prompt sound appear. It is limited to consuming a small amount of electricity when the cut signal runs. The second electric switch box connects the two circuit positions and serves as a magnetic control device installed on the side of the door 39 to stop the prompt sound.

[0077] The electric switch box 21 and the permanent magnet magnet rod box 3 can use the SD-8571 model product of SUNWAVE ELECTRONICS CO. LTD. in Shenzhen City, and can also select the SD-8581 model product with a connection wire led out from the end or other companies' round tubular magnetic electric switches. The reed tube 212 and the permanent magnet magnet rod 32 are filled with a synthetic glue liquid in the box, and are fixed after the glue liquid hardens.

[0078] When the door handle 38 is pulled down to open the door from inside the vehicle cabin, the reed switch 212 of the permanent magnet magnetic electric switch box 22 will be disconnected twice quickly, because the permanent magnet magnetic carrier 33 will pass the first electric switch box below twice when the door handle 38 is pulled down and bounces back, the magnetic field of the magnetic pole of the permanent magnet magnetic carrier 33 can just offset the magnetic force of the opposite magnetic pole of the third magnetic attraction piece 162, as long as the reed switch 212 in the box changes from connection to disconnection once, it can trigger the prompt sound. In fact, the first passing has triggered the prompt sound, but at that time the door is not yet opened, the effective magnetic field of the second permanent magnet strong magnetic piece 333 of the vehicle cabin floor 36 makes the reed switch 212 of the second electric switch box still connected, the prompt sound is hidden, but when the door 39 is slightly opened, the reed switch 212 of the second electric switch box is disconnected, and the prompt sound is emitted. If the magnetic pole of the third magnetic attraction piece 162 attached to the first electric switch box is the same as the downward magnetic pole of the permanent magnet magnetic carrier 33, the position needs to be changed to install the first electric switch box, as long as the first electric switch box is moved and installed so that the scale line of the side of the box without the third magnetic attraction piece 162 is aligned with the moving scale line of the permanent magnet magnetic carrier 33 above, the lateral deviation of no more than 3mm is effective installation, the same prompt sound can be obtained when the door handle 38 is pulled down to open the door from inside the vehicle cabin. The permanent magnet magnetic carrier 33 can also be installed on another type of door handle, even if the door handle can be attracted by the magnet.

[0079] The indicator body 1 can be installed at the side of the seat in the car (as shown in Fig. 2), because even if the car is hit by a traffic accident, the indicator body 1 will not harm the passengers.

Before sticking, the position must be free of oil and ground with the coarsest sandpaper, and then drill multiple shallow small holes in the range to enhance the fixing effect.

[0080] The main body 1 of the indicator can be installed on other parts of the door 39 in the vehicle cabin; the safety shield 10 above the sound box 12 has many sound transmission holes to facilitate the transmission of sound. The safety shield 10 can be temporarily fastened to the bottom edge of the main body 1 of the indicator by means of some inclined sliding small fastening positions provided near the edge of the shield below. To remove the safety shield 10, you only need to grab one of the short edges of the safety shield 10 below and pull it. The thickness of the main body 1 of the indicator together with the safety shield 10 is only 20.8 mm, and the space-occupying size is 137.5 mm x 91.5 mm x 20.8 mm.

[0081] As shown in FIGS. 1, 2, 28, 29, 43, 44, the first and second electric switch boxes can be covered with a round edge cover 20, and the connection wires long enough can be installed on various types of vehicles, and the excess connection wires can be wound in the wire storage reel 81, and then covered with the wire storage reel cover 82. The lower edge of the reel cover has a pair of symmetrical ears and two symmetrical notches, and the center of the ears has a round hole for screwing the reel cover, and the two notches can pass in and out of the wires. Alternatively, the excess wire in the middle of the connection wire can be cut, and then the two wires can be welded separately, and then wrapped with insulating tape. The wrapping position is preferably pushed between the back of the indicator body 1 and the door 39 to achieve a more beautiful effect. The first electric switch box is the permanent magnet electric switch box 22, and the second electric switch box is the electric switch box 21.

[0082] As shown in FIGS. 15, 16, the outside of the indicator body 1 is provided with a second accommodating groove 11 for placing the circuit board and the battery, a total electric switch 5, a sound box 12, and a sound stopping button combination 16 for stopping the sound of the sound box 12. The second accommodating groove 11 includes a battery compartment 111 and a circuit board compartment 112, and the circuit board compartment 112 includes a circuit board compartment bottom plate 112B sunk in the second accommodating groove 11, and the inside of the top of the battery cover 114 can just prevent two batteries from sliding out automatically.

[0083] As shown in FIGS. 23, 24, 25, 26, 27, 50, 51, the circuit board combination is placed in the circuit board compartment 112 on the back of the indicator body 1, and the first connection wire 1121 is led out from the circuit board and connected to the fourth electric switch box of the total electric switch 5; its connection method in the circuit is not fixed, because it is only an electric switch that can turn off the circuit. The total electric switch 5 includes a total electric switch bottom plate 51, a fourth electric switch box, a total electric switch upper cover 52, an electric switch push button 53, and a spring buckle 54 that can temporarily lock the electric switch push button 53 in the open or closed position, because the eaves below the push button have a pair of symmetrical recesses to match the convex design of the spring buckle 54; the bottom center of the electric switch push button body 531 has a recess to hide the third magnetic member 162, and then fixed with glue, which constitutes the electric switch push button 53.

[0084] The top of the main switch cover 52 has an open track for the push button to be pushed; when the push button 53 of the main switch is pushed to the middle of the main switch cover 52, the third magnetic attraction element 162 can magnetically connect the reed switch 212 in the fourth switch box to the circuit of the indicator. If the push button is pushed to the other side of the open track of the main switch cover 52, the internal contact of the reed switch 212 will be out of magnetic influence and become disconnected, causing the indicator to turn off.

[0085] As shown in FIG. 3, FIG. 4, FIG. 41, FIG. 50, FIG. 51, the second connecting wire 1122 is led out from the circuit board and connected to the first switch box below the door handle 38 in the car, which is the permanent magnet magnet switch box 22 at this time. The scale line beside the permanent magnet magnet must be aligned within 10 mm of the scale line of the permanent magnet carrier 33 above, and a lateral deviation of no more than 3 mm is also an effective installation. The third magnetic attraction element 162 can constantly connect the reed switch 212 of the permanent magnet magnet switch box 22 and face the magnetic field of the pole of the permanent magnet carrier 33 above with opposite poles. When the door handle 38 below the car is pulled, the prompt sound is obtained.

[0086] As shown in FIG. 1, FIG. 50, FIG. 51, the third connecting wire 1123 is led out from the circuit board and connected to the second switch box at the side of the car door 39. The second switch box can also be selected to be fixed to the back bottom of the indicator body 1, and then the indicator body 1 is installed on the car door 39 close to the car floor 36; the second permanent magnet 333 installed on the car floor 36 must be within 10 mm of the middle of one of the scale lines of the upper switch box 21, and a deviation of no more than 3 mm is also an effective installation, so that the effect of stopping the prompt sound when the car door 39 is closed is obtained.

[0087] As shown in FIG. 15, FIG. 16, FIG. 50, FIG. 51, the fourth connecting wire 1124 is led out from the circuit board and connected to the loudspeaker 121 of the sound box 12; the sound box 12 includes a sound box frame 122 with a screw-in pit on the outer wall and a sound box cover 123 with a correctly matched screw-in and screw-out convex position on the inner wall; the sound box cover 123 has many sound transmission holes to facilitate the transmission of sound. After the wire is welded to the loudspeaker 121, the wire is passed through the small hole in the bottom plate of the sound box frame 122 until the end, and the inner wall of the sound box frame 122 can just contact the circumferential position of the loudspeaker 121. Industrial glue is injected and sealed between the circumferential position and the inner wall of the sound box frame 122, and the gap between the above-mentioned double wires and the small hole is also sealed with industrial glue, so that water cannot enter the back of the loudspeaker 121 from above the loudspeaker 121 and the bottom of the indicator body 1. The loudspeaker 121 that is not waterproof on the back can be used, and the loudspeaker 121 becomes a waterproof loudspeaker 121.

[0088] As shown in Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 50, Fig. 51, the fifth connecting wire 1125 is connected to the stop sound button combination 16, which is a permanent magnet magnetic normally closed switch combination, located above the prompter body 1, and the top of the step has a square opening that matches the square body of the stop sound button 161, allowing it to move up and down to stop the prompt sound. The stop sound button 161 has a roof around it to limit its movement space, and the four corners of the square opening are two pairs of corners with different radii. The recess inside the square opening is just hidden and fixed with the third electric switch box 21 half box position, and the stop sound button 161 has a small hole that can hide a third magnetic member 162, and a spring 163 is placed against the stop sound button 161 bottom center protrusion. The spring 163 is supported by a support plate 164 with a fence, and the four corners of the support plate 164 are inverted and fixed to the bottom of the prompter body 1. Under the push of the spring 163, the permanent magnet of the stop sound button 161 is always aligned with one side of the magnetic switch of the third electric switch box 21, forming a normally closed switch made of permanent magnet magnetic force. When the stop sound button 161 is pressed to the end, the reed switch 212 of the electric switch box 21 will be out of the magnetic range and will not be powered, which will cut off the current at the appropriate circuit point of the prompter circuit, making the prompt sound stop immediately. When the stop sound button 161 is not pressed, the spring 163 can make the stop sound button 161 pop back to the top and restore the circuit of the prompter. The next time the door handle 38 is pulled down, the prompt sound will start again. Pressing the stop sound button 161 can only stop the prompt sound, but cannot turn off the prompter. The fence of the support plate 164 with a fence can prevent fingers or foreign objects from pushing away the spring 163, and the gap of the fence can also make the air in the space circulate, making it easy for water to evaporate. It can also be used to flush away accumulated dust. A flashing light can also be added next to the stop sound button 161 to enhance the prompt effect when the prompt sound is on. Just like some car anti-theft sounders also have flashing lights when they sound. This function is particularly useful for people with hearing impairment, but it consumes more power and is only suitable for cars with appropriate transformer power from the car itself.

[0089] As shown in Fig. 50, Fig. 51, the sixth connecting wire 1126 is welded to the battery compartment 111, and is connected to the circuit board at the bottom of the prompter body 1.

[0090] As shown in Fig. 50 and Fig. 51, the circuit board is put into the circuit board compartment 112 at the bottom of the prompter main body 1, and the circuit board has six connecting wires leading out, the first connecting wire 1121 is connected to the fourth electric switch box of the main electric switch 5, the second connecting wire 1122 is connected to the first electric switch box, the third connecting wire 1123 is connected to the second electric switch box, the fourth connecting wire 1124 is connected to the speaker 121 of the sound box 12, the fifth connecting wire 1125 is connected to the third electric switch box 21 of the stop button combination 16, and the sixth connecting wire 1126 is connected to the battery compartment 111 through the hole of the bottom plate 113 of the second accommodating groove. After the six connecting wires are connected to the circuit board, the circuit board carrier is pushed into the circuit board compartment 112 at the bottom of the prompter main body 1, and all the wires are sealed with industrial glue at the outlet of the recessed chamber to fill all the gaps.

[0091] The main function of the embodiment is to trigger a signal or voice prompt sound when the door in the vehicle compartment is opened, which aims to remind the passenger to check and take all the things that may still be left in the vehicle before leaving the vehicle. Closing the door 39 can automatically stop the prompt sound.

[0092] Subfunction 1: When prompting, only the stop button 161 needs to be pressed to immediately stop the prompt sound. After stopping the sound, there is no need to press the button again to restore the prompt sound function, because the pressing will not turn off the prompter, and the next sound content will automatically start from the beginning.

[0093] Subfunction 2: If the person in the vehicle compartment wants to avoid the prompt sound when opening the door this time, they can first press and hold the button with one to three fingers, then open the door with the other hand, and stop pressing the button when the door is opened more than two or three centimeters and the door handle 38 returns to the original position. Embodiment 2

[0094] As shown in Fig. 28, Fig. 29, Fig. 30 and Fig. 46, the circuit used in this embodiment is basically the same as that used in embodiment 1; the difference is that the permanent magnet rod box 3 replaces the permanent magnet magnet carrier 33 and is installed outside the door handle 38 in the vehicle compartment, and the electric switch box 21 replaces the permanent magnet magnet electric switch box 22, and is installed within 10 mm below the permanent magnet rod box 3 installed on the door handle 38 in the vehicle compartment, and the permanent magnet rod box 3 can also be covered with a protective cover 20; the second connecting wire 1122 connects the electric switch box 21 to the circuit board; the third connecting wire 1123 is connected to the electric switch box 21 installed on the side of the door 39, and the installation method is the same as that of the second electric switch box in embodiment 1, and the remaining connecting wire connection method is the same as that of embodiment 1.

[0095] The use and function of this embodiment are almost the same as those of Embodiment 1, except that when the second sub-function is used, the stop button 161 is pressed with one hand first and not released until the door is opened more than two or three centimeters, and then the pressing of the button is stopped, which eliminates the condition that the stop button must be pressed until the door handle 38 returns to its original position. Embodiment 3

[0096] As shown in Fig. 47, although this embodiment uses the same circuit as Embodiment 1 or Embodiment 2, the connection of the circuit is slightly changed. The magnetic sensing device installed on the door handle 38 is the same as that of Embodiment 1. The change is that a permanent magnet magnetic switch box 22 is connected in series before the stop button combination 16, and is installed on the door 39 near the floor 36 or the frame of the door 39 to replace the electric switch box 21 installed on the frame in the previous two embodiments as the stop of the prompt sound. The second permanent magnet strong magnet 333 installed on the floor 36 or the frame of the door 39 below or on the side within 10 mm must be aligned with the middle of the scale line of the approaching permanent magnet strong small magnet of the permanent magnet magnetic switch box 22 on the door 39 above or on the side, and a deviation of no more than 3 mm is effective. The third magnetic component 162 of the permanent magnet magnetic switch box 22 must be opposite to the magnetic pole of the magnetic pole of the electric wire part of the inner surface dry reed 212, which must be opposite to the magnetic pole of the second permanent magnet strong magnet 333 on the floor 36 or the frame of the door 39. Since the effective magnetic field of the second permanent magnet strong magnet 333 can exactly offset the magnetic force of the second electric switch box's permanent magnet strong small magnet on the side of the door 39 above or on the side, it can make the inner part of the related dry reed 212 not connected, so as to cut off the circuit of the prompter. One side of the second permanent magnet strong magnet 333 must have a color or engraved mark as a recognition of the direction of the magnetic pole during installation.

[0097] This embodiment is more energy-saving, because when the door 39 is closed, the current of the prompter is terminated. Unlike Embodiments 1 and 2, when the door 39 is closed, the sound stops, but the set sound flow continues until the set sound content is completed. The prompt sound function in this embodiment is the same as the previous one, and to perform the second sub-function described above, the method of Embodiment 1 must be used.

[0098] The installation of the invention on the door must first install the prompter main body 1, which is convenient for the installation of other devices.

[0099] As shown in Fig. 31, the permanent magnet strong magnet in the door handle 38 can be installed in the door handle 38. The permanent magnet magnet electric switch box 22 or the electric switch box 21 can be hidden in the proper position under the door handle 38; the stop button 161 can be installed beside the door handle 38, which can make the first and second auxiliary functions more convenient to use. There is also a push type main switch 5 nearby. The waterproof circuit board box and the waterproof speaker 121 can be installed in any position in the door 39. Moreover, the power source can come from the battery of the car (of course, after voltage reduction). A flashing light can also be installed on the door 39 in the car cabin to enhance the prompting effect when the alarm sounds. As in some car anti-theft alarm devices, a flashing light also lights up when the alarm sounds, which is convenient for the hearing-impaired to use. The aforementioned prompter main body 1 is better integrated into the car.

[0100] The present application installed on the future car only needs to expose the stop button 161 of the stop button combination 16 and the push button of the main switch 5. It can withstand the most extreme weather temperature and even be submerged in water without being damaged. It also will not cause flammable gas explosion. Example 4

[0101] As shown in Figs. 48 and 49, many business taxis have a device for opening and closing the door by the driver's button. If the device for prompting the alarm when leaving the car is installed on such a car, in addition to installing the aforementioned door 39 device, another device activated by the driver also needs to be installed. This device, when the driver starts the meter, will connect the electric switch 201 of the circuit in Fig. 48 or Fig. 49. The circuit in Fig. 49 is more stable and durable.

[0102] Before the passenger gets on the car, the driver's button opening the door for the passenger will not trigger the prompting alarm. However, when the passenger gets on the car, the driver starts the meter and also presses the button of the electric switch 201, thus connecting the circuit. When reaching the destination, the passenger pays the fare, and then the driver opens the door for the passenger to get off the car. At that time, the meter has stopped jumping, but it is still in the activated state. Therefore, the driver opening the door for the passenger to get off the car will also trigger the prompting alarm by pressing the normally open switch button of the circuit device. The signal reminds the passenger to take his own things and get off the car. After the passenger gets off the car, when the driver closes the door, it will also stop the prompting alarm by pressing the normally closed switch button of the circuit device. Then, the driver will return the meter to the unactivated state, and also turn off (so as not to connect) the sound box 12. If there is a driver who immediately returns the meter to the unactivated state after receiving the passenger's payment, and then opens the door for the passenger to get off the car. This is only a rare case, and the driver can be educated to correct it. The circuit device can use the electric switch box 21 of Examples 1-4 as the electric switch to prevent flammable gas explosion, and there are also designs of electric switches that prevent flammable gas explosion.

[0103] As shown in Fig. 33, the normally open switch 202 is placed in the center of a cylindrical normally open switch container 2021, which includes a normally open switch barrel 2022 and a normally open switch cover 2023 screwed to the normally open switch barrel 2022. A normally open switch shaft 2024 passes through the center of the normally open switch cover 2023 vertically to a normally open switch bearing 2025, and reaches a normally open switch button 2026 of the normally open switch 202. The lower part of the normally open switch shaft 2024 is fixed by a normally open switch fixing ring, and the top end of the normally open switch shaft 2024 is tightly inserted into the normally open switch button 2026. The normally open switch fixing ring and the normally open switch button 2026 lock the normally open switch shaft 2024 between the normally open switch bearing 2025 of the normally open switch cover 2023, allowing the normally open switch shaft 2024 to move up and down slightly. When the normally open switch cover 2023 is screwed, pressing the normally open switch button 2026 is equivalent to pressing the button of the normally open switch 202. Therefore, even if the flammable gas surrounds the screwed normally open switch container 2021, the extremely small spark generated by pressing the normally open switch button 2026 will not ignite the flammable gas outside the normally open switch container 2021.

[0104] Similarly, as shown in Fig. 32, the normally closed switch 203 of the circuit device is also placed in the center of a cylindrical, but larger, normally closed switch container 2031. The normally closed switch container 2031 includes a normally closed switch barrel 2032, a normally closed switch cover 2033, a normally closed switch shaft 2034, a normally closed switch bearing 2035, a normally closed switch button 2036, and a normally closed switch fixing ring 2037. Since the two boxes have the same construction principle, even if the box is surrounded by flammable gas, pressing the button of the box will not ignite the flammable gas outside the box to explode.

[0105] The main body of the circuit device is a sound emitting box 12, and the circuit is the circuit of Fig. 48 or Fig. 49. The power supply can come from the battery of the vehicle (of course, after voltage reduction processing). The sound emitting box can be installed at any position in the vehicle cabin that can emit loud sound when broadcasting. Of course, the device also takes into account road safety. The sound emitting box has two groups of wires leading out, the first group of wires leading out from the circuit of the sound emitting box to the electrical switch 201 that can be connected at the same time as the starting of the metering charging table and the normally open switch 202 that will be connected at the same time when the button is pressed to open the door 39, the two switches are connected in series. The wires are led out from the X point and the Z point in the circuit diagram. The electrical switch 201 can be started by the driver at the same time as the starting of the metering charging table to connect the X point and the Y point in the circuit diagram.

[0106] The normally open switch 202 is connected from the Y point and the Z point in the circuit diagram, and is placed in the small cylindrical container. When the driver presses the button to open the door, the button can be touched to make the sound box 12 broadcast the prompt sound. Of course, the driver will not trigger the prompt sound when the meter is not started. The second group of wires is connected from the W point and the Z point in the circuit diagram to the normally closed switch 203 in the larger cylindrical container. When the driver presses the button to close the door, the button can be touched to stop the broadcast of the prompt sound. When the meter is pulled to the unstarted state, the circuit of the prompter is terminated.

[0107] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
