Description

Technical Field

[0001] This utility model relates to the field of automotive alarm technology, and in particular to an automotive fire prediction alarm device. Background Technology

[0002] Car fires often originate from electrical faults, fuel leaks, etc., and can spread rapidly in the early stages. This device is equipped with a flame sensor that can accurately identify the specific light signals of a fire flame. Once an anomaly is detected, it immediately triggers an audible and visual alarm inside the vehicle, promptly reminding the driver and passengers to check or evacuate, thus buying time for fire response.

[0003] Existing car fire alarm devices mostly rely on a single warning light or buzzer, which has limited warning effect and is difficult to quickly attract the driver's attention; moreover, the transmission structure of some devices is prone to accidental triggering or inconvenient to reset, making it difficult to maintain the initial state stably when no fire occurs, and difficult to efficiently switch to the alarm state after a fire occurs, thus delaying the opportunity to deal with the fire.

[0004] Based on this, a vehicle fire prediction and alarm device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a car fire prediction and alarm device in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A car fire prediction and alarm device includes an alarm box, a cover rotatably connected to the alarm box, a flip-up groove on the cover, a warning plate rotatably connected inside the alarm box, a torsion spring connected to the connection between the warning plate and the alarm box, a transmission rod rotatably connected inside the alarm box, a pressing block and a bevel gear connected to the transmission rod, and a transmission mechanism for driving the bevel gear to rotate inside the alarm box.

[0007] Preferably, a first docking block is connected to one side of the warning plate, and a second docking block is connected inside the alarm box.

[0008] Preferably, the transmission mechanism includes an adjusting rod, on which a bevel gear and a prism block are connected. The adjusting rod is rotatably connected to the alarm box. A clamping piece is provided on the outside of the prism block. The clamping piece is connected to a connecting piece via a connecting rod. A magnetic block is connected to the connecting piece. An electromagnet is provided between the magnetic blocks. The electromagnet is connected to a control circuit built into the alarm box via a lead wire. A flame sensor is connected to the control circuit.

[0009] Preferably, a limit button is connected to the adjusting rod, and a stop block is connected to the alarm box.

[0010] Preferably, a limit frame is connected to the alarm box, and the connecting rod is slidably connected to the limit frame.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This application adopts a "warning board + torsion spring" structure. When a fire occurs, the torsion spring can drive the warning board to flip up from the flip slot and stand up. Compared with traditional warning lights, it is easier to attract the driver's attention and help to quickly detect the fire.

[0012] 2. This application adopts a transmission control structure of "electromagnet + magnetic block + clamping plate". When no fire occurs, it can stably clamp the edge block to limit the rotation of the adjustment rod and avoid the warning plate from being triggered accidentally. When a fire occurs, the structure can be released when the electromagnet is de-energized to realize the alarm, thus improving the stability and response efficiency of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A car fire prediction and alarm device includes an alarm box 1, a cover 2 rotatably connected to the alarm box 1, a flip groove 3 on the cover 2, a warning plate 4 rotatably connected inside the alarm box 1, the warning plate 4 flips up from the flip groove 3, which can attract the driver's attention more than structures such as warning lights. Since fire is a high-risk situation that needs to be dealt with immediately, a torsion spring 9 is connected to the connection between the warning plate 4 and the alarm box 1, the torsion spring 9 can drive the warning plate 4 to flip to a vertical state, a transmission rod 10 rotatably connected inside the alarm box 1, a pressing block 5 and a bevel gear 11 connected to the transmission rod 10, and a transmission mechanism for driving the bevel gear 11 to rotate inside the alarm box 1.

[0017] Specifically, such as Figure 2 and Figure 3 As shown, a docking block 8 is connected to one side of the warning plate 4, and a docking block 13 is connected inside the alarm box 1. The docking block 8 is connected to the circuit inside the warning plate 4, while the docking block 13 is connected to the circuit inside the alarm box 1. When the docking block 8 and the docking block 13 are docked, the metal interfaces of the circuits on the two structures are connected to each other, thereby connecting the internal circuits and causing the flashing light and buzzer connected to the circuit to operate.

[0018] Specifically, such as Figure 2 and Figure 4 As shown, the transmission mechanism includes an adjusting rod 6, on which a second bevel gear 12 and a prism block 16 are connected. The second bevel gear 12 meshes with the first bevel gear 11. The adjusting rod 6 is rotatably connected to the alarm box 1. A clamping plate 15 is provided on the outer side of the prism block 16. The clamping plate 15 is located on the upper and lower sides of the prism block 16. The clamping plate 15 can clamp the prism block 16, thereby preventing the prism block 16 from rotating. The clamping plate 15 is connected to a connecting plate 18 through a connecting rod 17. A magnetic block 20 is connected to the connecting plate 18. An electromagnet 19 is provided between the magnetic blocks 20. The magnetic blocks 20 and the electromagnet 19 are of the same polarity. When the electromagnet 19 is energized, it will repel the magnetic blocks 20. In order to ensure the repulsion effect, multiple coils can be wound on the electromagnet 19. The electromagnet 19 is connected to the control circuit built into the alarm box 1 through a lead wire. A flame sensor is connected to the control circuit.

[0019] Specifically, such as Figure 1 As shown, a limit button 14 is connected to the adjusting rod 6, and a stop block 7 is connected to the alarm box 1. There are two stop blocks 7, which limit the rotation of the limit button 14 so that the limit button 14 will only rotate 90 degrees.

[0020] Specifically, such as Figure 4 As shown, a limit frame 21 is connected to the alarm box 1, and the connecting rod 17 is slidably connected to the limit frame 21. The limit frame 21 limits the connecting rod 17, so that the connecting rod 17 can only move vertically up and down.

[0021] In summary, the car fire prediction and alarm device provided in this embodiment is installed on the car dashboard. The photosensitive element of the flame sensor inside the device is connected to the car interior to monitor the specific wavelength light emitted by the fire flame. When the flame sensor detects a flame inside the car, the control circuit de-energizes the electromagnet 19. At this time, the electromagnet 19 does not have magnetic force, so it cannot repel the magnetic block 20 from moving away from the electromagnet 19. The magnetic block 20 and the electromagnet 19 are in a state of opposite polarity. At this time, the warning plate 4 can be flipped from a horizontal state to a vertical state under the action of the torsion spring 9.

[0022] When docking block 8 and docking block 13 on warning board 4 are connected, the circuit on warning board 4 is turned on, which causes the flashing light and buzzer on warning board 4 to operate, allowing the driver to check for faults in a timely manner.

[0023] When no fire occurs, the electromagnet 19 is energized, repelling the magnetic blocks 20 set above and below from the electromagnet 19. Together with the clamping plate 15, it clamps the edge block 16. At this time, the adjusting rod 6 cannot rotate. Through the transmission rod 10, the pressing plate 5 is kept in a horizontal state, so as to press the warning plate 4 and ensure that the warning plate 4 is in a horizontal state.

[0024] After the fire hazard investigation is completed, the warning plate 4 can be manually pressed down by overcoming the torsion spring 9, and then the clamping plate 15 can be overcome and the limit button 14 can be rotated to ensure that the pressing block 5 completes the limit of the warning plate 4 through the transmission rod 10 via the adjusting rod 6.

[0025] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
