Description
Technical Field
[0001] The utility model relates to a warning device, in particular to an omnidirectional automobile driving state warning device, belonging to the technical field of automobile electronic equipment. Background Art
[0002] Existing cars are typically equipped with driving status warning lights, such as reverse lights, brake lights, and turn signals, which can provide warnings for driving conditions such as reversing, braking, turning, and hazard warnings. However, there are no corresponding warnings for other driving conditions, especially for critical driving conditions such as accelerating, decelerating, and abnormal driving. On crowded highways, where vehicle spacing is very limited, the lack of comprehensive driving status warning systems makes it difficult for drivers of following vehicles to accurately and promptly understand the driving status of the vehicle ahead, making traffic accidents very likely. Furthermore, current hazard warnings are limited to flashing the front and rear turn signals via a hazard warning switch, which is still not clear enough. Utility Model Content
[0003] The purpose of the utility model is to provide an all-round automobile driving status warning device, which can increase the external display of the automobile's refueling acceleration, deceleration and abnormal driving status based on the original automobile warning light control circuit, and can upgrade the danger warning to make it clearer to the outside.
[0004] The technical solutions adopted in this utility model are as follows:
[0005] A comprehensive vehicle driving status warning device is expanded on the basis of the original warning light control circuit of the vehicle. The specific expanded circuit is as follows: after the vehicle ignition switch is turned on, the positive electrode of the power supply is connected to one end of the handbrake switch K4 through the fuse F1, and the other end of the handbrake switch K4 is connected to the common end of the accelerator pedal first-break-before-make switch K2. The normally open end of the accelerator pedal first-break-before-make switch K2 is connected to the positive electrodes of the green warning lights L1, L2, and L3, and the negative electrodes of the green warning lights L1, L2, and L3 are connected to the negative electrode of the power supply; the normally closed end of the accelerator pedal first-break-before-make switch K2 is connected to the input end of the flash relay JK, and the output end of the flash relay JK is connected to the positive electrodes of the yellow warning lights L4, L5, and L6, and the negative electrodes of the yellow warning lights L4, L5, and L6 are connected. The positive pole of the car's normal power supply is connected to the normally closed end of the brake pedal break-before-make switch K3, and the common end of the brake pedal break-before-make switch K3 is connected to the negative pole of the power supply; the positive pole of the car's normal power supply is connected to one end of the hazard warning switch K1 through the fuse F2, and the other end of the hazard warning switch K1 is connected to the input end of the flasher relay JK; the positive pole of the car's normal power supply is connected to the positive poles of the red warning lights L7, L8, and L9 through the fuse F3, and the negative poles of the red warning lights L7, L8, and L9 are connected to the normally open end of the brake pedal break-before-make switch K3; the positive pole of the car's normal power supply is connected to the positive poles of the left and right rear brake lights L10 and L11 through the fuse F3, and the negative poles of the left and right rear brake lights L10 and L11 are connected to the normally open end of the brake pedal break-before-make switch K3.
[0006] The handbrake switch K4 is a position switch that closes when the handbrake is released; the accelerator pedal break-before-make switch K2 is a position switch that is triggered when the accelerator pedal is depressed; and the brake pedal break-before-make switch K3 is a position switch that is triggered when the brake pedal is depressed.
[0007] The hazard warning switch K1 and the left and right rear brake lights L10 and L11 are the hazard warning switch and the left and right rear brake lights in the original circuit of the car.
[0008] The green warning light L1, yellow warning light L4 and red warning light L7 are installed together at the position of the original high-mounted brake light on the rear window of the car, used to replace the original high-mounted brake light; the green warning light L2, yellow warning light L5 and red warning light L8 are installed together on the left front fender of the car, and the green warning light L3, yellow warning light L6 and red warning light L9 are installed together on the right front fender of the car.
[0009] This all-around vehicle driving status warning device builds upon the vehicle's existing warning light control circuit by adding three sets of yellow, green, and red warning lights and corresponding expansion circuits to enhance the vehicle's external hazard warnings. This device can display the vehicle's acceleration, deceleration, and abnormal driving conditions, and upgrades the hazard warning system to make it even clearer. Furthermore, the additional warning lights, mounted on the rear window and front fenders, display the vehicle's driving status from a wider range of angles. Therefore, this warning device complements existing vehicle driving status warning lights. With this device installed, the driver of the following vehicle can synchronize their speed control with the preceding driver based on the preceding vehicle's warning lights. The device can also assess the road conditions the preceding driver sees, allowing them to take timely and corrective actions to avoid accidents and ensure driving safety. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is the circuit principle diagram of this all-round automobile driving status warning device. DETAILED DESCRIPTION
[0011] The present invention will be further described below with reference to the accompanying drawings.
[0012] like Figure 1 As shown, the all-round vehicle driving status warning device is expanded on the basis of the original warning light control circuit of the vehicle. The specific expanded circuit is: after the vehicle ignition switch is turned on, the positive pole of the power supply is connected to one end of the handbrake switch K4 through the fuse F1, and the other end of the handbrake switch K4 is connected to the common end of the accelerator pedal first-break-before-make switch K2. The normally open end of the accelerator pedal first-break-before-make switch K2 is connected to the positive poles of the green warning lights L1, L2, and L3, and the negative poles of the green warning lights L1, L2, and L3 are connected to the negative pole of the power supply; the normally closed end of the accelerator pedal first-break-before-make switch K2 is connected to the input end of the flash relay JK, and the output end of the flash relay JK is connected to the positive poles of the yellow warning lights L4, L5, and L6, and the negative poles of the yellow warning lights L4, L5, and L6 are connected. The positive pole of the car's normal power supply is connected to the normally closed end of the brake pedal break-before-make switch K3, and the common end of the brake pedal break-before-make switch K3 is connected to the negative pole of the power supply; the positive pole of the car's normal power supply is connected to one end of the hazard warning switch K1 through the fuse F2, and the other end of the hazard warning switch K1 is connected to the input end of the flasher relay JK; the positive pole of the car's normal power supply is connected to the positive poles of the red warning lights L7, L8, and L9 through the fuse F3, and the negative poles of the red warning lights L7, L8, and L9 are connected to the normally open end of the brake pedal break-before-make switch K3; the positive pole of the car's normal power supply is connected to the positive poles of the left and right rear brake lights L10 and L11 through the fuse F3, and the negative poles of the left and right rear brake lights L10 and L11 are connected to the normally open end of the brake pedal break-before-make switch K3.
[0013] The handbrake switch K4 is a position switch that closes when the handbrake is released; the accelerator pedal break-before-make switch K2 is a position switch that is activated when the accelerator pedal is depressed; and the brake pedal break-before-make switch K3 is a position switch that is activated when the brake pedal is depressed. Preferably, the accelerator pedal break-before-make switch K2 is located at 1 / 5 of the total accelerator pedal travel, and is activated when the accelerator pedal is depressed for more than 1 / 5 of the total travel.
[0014] The hazard warning switch K1 and the left and right rear brake lights L10 and L11 are the hazard warning switch and the left and right rear brake lights in the original circuit of the car.
[0015] The green warning light L1, yellow warning light L4 and red warning light L7 are installed together at the position of the original high-mounted brake light on the rear window of the car, used to replace the original high-mounted brake light; the green warning light L2, yellow warning light L5 and red warning light L8 are installed together on the left front fender of the car, and the green warning light L3, yellow warning light L6 and red warning light L9 are installed together on the right front fender of the car.
[0016] Combine Figure 1 The specific working process of the omnidirectional vehicle driving status warning device is as follows:
[0017] After the driver starts the car and releases the parking brake to prepare for departure, parking brake switch K4 closes. When the driver presses the accelerator pedal, triggering the accelerator pedal break-before-make switch K2, its normally closed terminal opens and its normally open terminal closes. Green warning lights L1, L2, and L3 on the rear window and left and right front fenders illuminate, indicating that the vehicle is accelerating. If the vehicle is moving forward, the road ahead is currently clear. If the vehicle is reversing, it indicates that it is accelerating. In exceptional cases, if the vehicle is accelerating but green warning lights L1, L2, and L3 are not illuminated, this indicates that the vehicle is in an abnormal state of braking with the parking brake engaged, suggesting that the driver may be inexperienced.
[0018] When the driver releases the accelerator pedal and the accelerator pedal break-before-make switch K2 returns to its position, its normally open end opens and its normally closed end closes, the green warning lights L1, L2, and L3 are de-energized and extinguished, and the positive pole of the power supply is supplied to the positive poles of the yellow warning lights L4, L5, and L6 through the normally closed end of the accelerator pedal break-before-make switch K2 and the flasher relay JK. The negative poles of the yellow warning lights L4, L5, and L6 are connected to the negative pole of the power supply through the normally closed end of the brake pedal break-before-make switch K3. Therefore, the yellow warning lights L4, L5, and L6 on the rear window and the left and right front fenders of the vehicle are energized and flash repeatedly under the control of the flasher relay JK, indicating that the vehicle is in a state of reducing fuel and decelerating, and may brake or stop at any time. Please keep a distance from the following vehicle. The following vehicle can brake in advance according to the prompt, thereby greatly reducing the braking distance and greatly reducing the possibility of accidents such as rear-end collisions and side collisions.
[0019] When the driver steps on the brake pedal to trigger the brake pedal break-before-make switch K3, its normally closed end is disconnected and the normally open end is closed. The yellow warning lights L4, L5, and L6 are de-energized and extinguished, and the red warning lights L7, L8, and L9 on the rear window and the left and right front fenders are energized and lit. At the same time, the left and right rear brake lights L10 and L11 are also energized and lit, indicating that the vehicle is in braking state and may stop at any time. Vehicles behind please keep a distance.
[0020] When the driver depresses both the accelerator and brake pedals, the accelerator pedal break-before-make switch K2 and the brake pedal break-before-make switch K3 are triggered simultaneously, their normally closed ends open and their normally open ends close. As a result, the green warning lights L1, L2, L3 and the red warning lights L7, L8, L9 as well as the left and right rear brake lights L10 and L11 light up simultaneously, indicating that the vehicle is in an abnormal state of both accelerating and braking. This indicates that the driver may be inexperienced in driving skills, or is in an unfavorable state such as extreme fatigue or drunkenness, thereby reminding the drivers of the following vehicles to be careful and guard against accidents.
[0021] When the driver presses the hazard warning switch K1, the vehicle not only maintains the original flashing of the front and rear turn signals, but also receives power from the positive terminal of the power supply through the hazard warning switch K1 and flasher relay JK to the positive terminals of the yellow warning lights L4, L5, and L6. The negative terminals of the yellow warning lights L4, L5, and L6 are connected to the negative terminal of the power supply via the normally closed terminal of the brake pedal break-before-make switch K3. As a result, the yellow warning lights L4, L5, and L6 on the rear window and the left and right front fenders are energized and flash repeatedly under the control of the flasher relay JK. This flashing hazard warning is visible all around the vehicle, with the warning being most noticeable behind the vehicle, making it easier for following drivers to notice and take appropriate action. In exceptional cases, if the front and rear turn signals and yellow warning lights L4, L5, and L6 also illuminate simultaneously with the green warning lights L1, L2, and L3, this indicates that the vehicle is in a dangerous state and accelerating, and surrounding vehicles should promptly give way.
[0022] The above-mentioned figures are only typical embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
