Description

Technical Field

[0001] This invention relates to a waiting and warning device for motor vehicles and trolleybuses, mainly referring to a device that can provide a warning when a motor vehicle, trolleybus, or two-wheeled electric vehicle is traveling to a waiting position. Background Technology

[0002] Locomotives and trams (i.e., locomotives and electric vehicles) are commonly used means of transportation. In order to improve the safety of locomotives and trams, a waiting area is set up in front of the next intersection when locomotives and trams turn left. Therefore, locomotives and trams can first move to the waiting area and stop, and then go straight when the intersection turns green. This can avoid the unsafe situation of collision that may occur when locomotives and trams turn left at the same time as cars.

[0003] However, other drivers on the road do not know whether the vehicle or tram should go straight or proceed to the turning area when the light is green at the intersection. Therefore, other drivers cannot give way to make it easier for the vehicle or tram to proceed to the turning area, resulting in congestion and unsafe conditions.

[0004] In addition, conventional automobiles and large motorcycles have parking and fault warning switches to turn on and off warning lights. These warning lights are designed to make the front and rear turn signals of the vehicle flash simultaneously. However, when the turn signals are turned on, they are ineffective. Even if the vehicle ignition is turned off, the flashing of the front and rear turn signals cannot be stopped. The warning switch must be turned off to stop them. This results in a functional conflict between the turn signals and the warning lights and makes them difficult to control. Summary of the Invention

[0005] The purpose of this invention is to provide a waiting and warning device for locomotives and trams, which can provide warnings for locomotives and trams when waiting to turn in order to improve driving safety.

[0006] The standby and warning device for locomotives and trams of the present invention includes a manual switch, an electronic switch unit, a delay circuit, at least one warning light, and a flasher. The electronic switch unit is electrically connected to the manual switch; the delay circuit is electrically connected to the electronic switch unit and the manual switch; the warning light is electrically connected to the electronic switch unit; and the flasher is electrically connected to a power supply, the electronic switch unit, and the manual switch. When the manual switch is activated, the electronic switch unit is activated, and the warning light flashes. When the manual switch is activated for more than the set time of the delay circuit, the warning light stops flashing.

[0007] In one embodiment of the present invention, the manual switch is a turn signal switch for the vehicle body, which controls the operation of the turn signals of the vehicle body.

[0008] In one embodiment of the present invention, the electronic switch unit is electrically connected to the turn signal, and when the electronic switch unit is activated, it causes the warning light and the turn signal to flash simultaneously.

[0009] In one embodiment of the present invention, the electronic switching unit has a thyristor SCR, the gate (G) of the thyristor SCR is electrically connected to a manual switch, and the base (K) of the thyristor SCR is electrically connected to a delay circuit.

[0010] In one embodiment of the present invention, the electronic switch unit further includes a relay Relay1, which is electrically connected to the thyristor SCR and the flasher, and the normally open contact of the relay Relay1 is electrically connected to the warning light.

[0011] In one embodiment of the present invention, the delay circuit has an RC charging and discharging circuit.

[0012] In one embodiment of the present invention, a reset circuit is further included, which provides a discharge path for the RC charging and discharging circuit.

[0013] In one embodiment of the present invention, the manual switch is a turn signal switch for the vehicle body. The manual switch has an R contact, an L contact and an OFF terminal. The R contact is electrically connected to a delay circuit and the L contact is electrically connected to a reset circuit.

[0014] In one embodiment of the present invention, a control circuit is also included, which causes the left turn signal to not illuminate when the manual switch is at contact R.

[0015] This invention can provide warnings for locomotives and electric vehicles when they are waiting to turn, stuck in traffic, or experiencing a malfunction, which can greatly improve driving safety. This invention can be controlled using the vehicle's existing turn signal switch, which has better operation and installation convenience. Attached Figure Description

[0021] Label Explanation: 1--Manual switch 2--Electronic Switching Unit 3--Delay circuit 4--Reset Circuit 5--Warning Light 6--Flasher. Detailed Implementation

[0022] Please see Figure 1 The standby and warning device for locomotives and trams of the present invention includes a manual switch 1, an electronic switch unit 2, a delay circuit 3, at least one warning light 5, and a flasher 6. The electronic switch unit 2 is electrically connected to the manual switch 1; the delay circuit 3 is electrically connected to both the electronic switch unit 2 and the manual switch 1; the warning light 5 is electrically connected to the electronic switch unit 2; and the flasher 6 is electrically connected to a power source, the electronic switch unit 2, and the manual switch 1. Operation of the manual switch 1 activates the electronic switch unit 2 and causes the warning light 5 to flash; operation of the manual switch 1 exceeding a set time in the delay circuit 3 causes the warning light 5 to stop illuminating.

[0023] Figure 2 The circuit diagram for the first embodiment of the present invention uses the vehicle's existing turn signal switch as the manual switch 1. Two warning lights 5 are located on opposite sides of the vehicle body, and a reset circuit 4 can be added. The manual switch 1 has an R contact, an L contact, and an OFF terminal. The R contact of the manual switch 1 is electrically connected to the right turn signal at the front and rear of the vehicle body, and the L contact is electrically connected to the left turn signal at the front and rear of the vehicle body. The manual switch 1 is electrically connected to an electronic switch unit 2 composed of a thyristor SCR and a relay Relay 1. The R contact of the manual switch 1 is electrically connected to the G terminal of the thyristor SCR, and the A terminal of the thyristor SCR is electrically connected to the relay Relay 1 and the power supply B+. The relay Relay 1 is electrically connected to a flasher 6, and the normally open contact of the relay Relay 1 is electrically connected to the warning lights 5. The electronic switch unit 2 and the manual switch 1 are electrically connected to a delay circuit 3 mainly composed of a resistor R, a capacitor C, a diode Z, a transistor Q1, and a transistor Q2. The R contact of manual switch 1 is electrically connected to an RC charging and discharging circuit consisting of resistor R and capacitor C. Capacitor C is electrically connected to the gate (G) of transistor Q1 and diode Z. The drain (D) of transistor Q1 is electrically connected to the gate (G) of transistor Q2. The base (K) of the thyristor SCR and the source (S) of transistor Q2 are grounded. Manual switch 1 and delay circuit 3 are electrically connected to reset circuit 4, which mainly consists of transistors Q3 and Q4. The L contact of manual switch 1 is electrically connected to the gate (G) of transistors Q3 and Q4. The drain (D) of transistor Q3 is electrically connected to capacitor C. The source (S) of transistor Q3 is grounded and provides a discharge path for capacitor C. The drain (D) of transistor Q4 is electrically connected to the gate (G) of transistor Q2. The source (S) of transistor Q4 is grounded. Flasher 6 is electrically connected to power supply B+, manual switch 1, and electronic switch unit 2.

[0024] In the first embodiment of the present invention, the delay time of the delay circuit 3 can be set to about 1 second. When the manual switch 1 is switched to the R contact, the right turn signal illuminates; when the manual switch 1 is switched to the L contact, the left turn signal illuminates, providing a normal turn signal warning. When waiting to turn while driving, or when there is a blockage or malfunction ahead requiring a warning, the manual switch 1 can be switched sequentially to the L contact, OFF terminal, R contact, and OFF terminal, with the duration at the R contact being less than 1 second. This allows the input current at the R contact of the manual switch 1 to trigger the G terminal of the thyristor SCR, causing the thyristor SCR to conduct and the relay Relay 1 to conduct. This allows the input current of the flasher 6 to flash through the normally open contact of the relay Relay 1, causing the warning light 5 to flash and provide a warning. When no switching or warning is needed, manual switch 1 can be switched from the OFF terminal to the R contact, and the duration of the R contact exceeds 1 second. This causes capacitor C to charge to a voltage exceeding the forward voltage of the condenser diode Z, causing the condenser diode Z and transistor Q1 to conduct, and transistor Q2 to turn off, so that the thyristor SCR and relay Relay1 do not conduct, and the warning light 5 stops flashing.

[0025] In this embodiment of the invention, when the warning light 5 is to be activated again, the manual switch 1 can be switched between OFF terminal → L contact → OFF terminal → R contact → OFF terminal in a short period of time. When switching to the L contact, transistors Q3 and Q4 in the reset circuit 4 are turned on, causing capacitor C to discharge through transistor Q3, thus preventing transistor Q1 from conducting. The conduction of transistor Q4 ensures that transistor Q2 is not conducting. Therefore, a reset can be performed before controlling the flashing action of the warning light 5 to improve the stability of the action.

[0026] Figure 3 This is a circuit diagram of the second embodiment of the present invention. The second embodiment is similar to the first embodiment, except that the electronic switch unit 2 also has a relay Relay2. The common contact of relay Relay2 and relay Relay1 is connected to the flasher 6. The normally open contact of relay Relay1 is electrically connected to the warning light 5 and the left turn signal, and the normally open contact of relay Relay2 is electrically connected to the right turn signal. Therefore, when the warning light 5 is controlled to flash by the manual switch 1, the left and right turn signals can flash simultaneously, which can have a better warning effect.

[0027] Figure 4This is a circuit diagram of the third embodiment of the present invention. The third embodiment is similar to the second embodiment, with the main difference being the addition of a control circuit composed of transistors Q5, Q6, Q7 and relay Relay3. The gate (G) of transistor Q5 is electrically connected to the R contact of manual switch 1, the source (S) of transistor Q5 is grounded, the drain (D) of transistor Q5 is connected to relay Relay3, relay Relay3 is connected to flasher 6, the normally closed contact of relay Relay3 is electrically connected to relay Relay1, and the normally open contact of relay Relay3 is electrically connected to the gate (G) of thyristor SCR. The common contact of relays Relay2, Relay1, and Relay3 is electrically connected to the flasher 6. The normally open contact of relay Relay2 is electrically connected to the right turn signal. The normally open contact of relay Relay1 is electrically connected to the source (S) of transistor Q6. Transistor Q6 is a P-type FET. The drain (D) of transistor Q6 is connected to the warning light 5 and the left turn signal. The gate (G) of transistor Q6 is connected to the drain (D) of transistor Q7. The gate (G) of transistor Q7 is connected to the drain (D) of transistor Q5. The source (S) of transistor Q7 is grounded.

[0028] In the third embodiment of the present invention, when manual switch 1 is switched to the R contact, the right turn signal flashes, transistor Q5 and relay Relay 3 are turned on, triggering the thyristor SCR. Power supply B+ voltage causes relay Relay 2 to operate and the thyristor SCR to turn on. Relay 3 corresponds to the flasher 6 switching approximately 85 times per minute; therefore, relay Relay 3 and relay Relay 1 correspond to switching operations. When manual switch 1 is switched to the R contact, transistor Q5 is turned on, transistor Q7 is turned off, and transistor Q6 is also turned off, ensuring that the left turn signal does not illuminate when switched to the R contact, providing a more stable directional indication.

[0029] Figure 5 This is a circuit diagram of the fourth embodiment of the present invention. The fourth embodiment operates on the same principle as the second embodiment, and integrates the delay circuit and electronic switch control into the IC, which can be controlled by a program to have the functions claimed by the present invention. The IC can also integrate the flasher 6 or other circuits into its IC circuit. The IC with the aforementioned functions is an equivalent design of the present invention and should also fall within the scope of the present invention.

[0030] Therefore, as described above, the present invention can provide warnings for locomotives and electric vehicles when they are waiting to turn, in traffic jams, or experiencing malfunctions, which can significantly improve driving safety. Furthermore, the present invention utilizes the vehicle's existing turn signal switch, offering better control and installation convenience. The foregoing embodiments are illustrative of the present invention and are not intended to limit the invention; any equivalent modifications made in accordance with the spirit of the present invention should also fall within the scope of the present invention.
