Description

Technical Field

[0001] This utility model relates to the field of window opening control technology, specifically to a temperature detection circuit and a car window control device. Background Technology

[0002] Fires have become increasingly frequent in recent years, especially during the dry winter season. Currently, windows are typically controlled by smoke detectors based on smoke levels or carbon monoxide detectors based on carbon monoxide concentration. However, when smoke or carbon monoxide levels are high, opening windows can easily ignite the fire and worsen the situation. Similarly, while vehicles are in motion, smoke detectors or carbon monoxide detectors control window opening to prevent occupants from being unable to escape in case of spontaneous combustion. However, in the event of a fire, the window opening circuit may be interrupted, preventing the windows from opening and hindering timely evacuation. Therefore, traditional methods cannot predict abnormal phenomena in the early stages of an accident. Utility Model Content

[0003] In view of this, the present invention provides a temperature detection circuit and a window control device, which can prevent the prediction of abnormal phenomena in the early stage of an accident by traditional methods, thus causing trapped personnel to be unable to escape danger in time.

[0004] In a first aspect, this utility model provides a temperature detection circuit, including: a battery, a temperature detection switch, a lift assembly switch, multiple drive motors and at least one intermediate relay, wherein each drive motor is connected to an intermediate relay and each drive motor drives a window to open. A temperature detection switch has its first end connected to the negative terminal of the battery and its second end connected to the negative terminal of each intermediate relay. It is used to energize each intermediate relay when the current ambient temperature is determined to be abnormal. Each intermediate relay has its common terminal connected to the negative terminal of the battery, and its positive terminal connected to the positive terminal of the battery. The lift assembly switch has its positive input terminal connected to the positive terminal of the battery, its negative input terminal left floating, and its negative output terminal connected to the normally closed terminal of each intermediate relay. Each drive motor has its negative terminal connected to the normally open terminal of the corresponding intermediate relay, and its positive terminal connected to the positive output terminal of the lift assembly switch. This is used to drive the corresponding window to open after each intermediate relay is energized.

[0005] This embodiment replaces the traditional carbon monoxide or smoke detection switches with a temperature detection switch. By controlling the opening of windows before a fire occurs, the system can anticipate potential dangers and prevent them from happening in the first place. This avoids the situation where, after an accident has occurred, reactive measures are taken that fail to help trapped people escape danger in time.

[0006] In some alternative implementations, the temperature detection switch includes a temperature sensor and a temperature switch, wherein a first end of the temperature sensor is connected to the negative terminal of the battery, and a second end of the temperature sensor is connected to the first end of the temperature switch. A temperature switch, the second terminal of which is connected to the negative terminal of each intermediate relay, is used to turn on when the temperature sensor detects that the current ambient temperature exceeds the preset ambient temperature, thereby energizing each intermediate relay.

[0007] This embodiment replaces the traditional carbon monoxide or smoke detection switches with a specific temperature detection switch. By controlling the opening of windows through temperature detection before a fire occurs, it is possible to anticipate potential dangers and prevent them from happening in the first place. This avoids the situation where, after an accident has occurred, reactive measures are taken and trapped personnel cannot be assisted in time to escape danger.

[0008] In some optional embodiments, the temperature detection circuit of this invention further includes: a solenoid valve switch, a binding device, and a time relay, wherein the time relay is connected to an intermediate relay.

[0009] The solenoid valve switch has its positive terminal connected to the positive terminal of each drive motor, and its negative terminal connected to the negative terminal of the bonding device and the time relay; Binding devices are used to bind objects and ensure their safety. The time relay has its positive terminal connected to the positive terminal of each drive motor and its negative terminal connected to the normally open terminal of its corresponding intermediate relay. When each intermediate relay is energized, if the current detection time is greater than the preset detection time, the solenoid valve is energized, thereby opening the bonding device.

[0010] This embodiment energizes each intermediate relay when an anomaly is detected in the current detection time. In addition to supporting temperature anomaly detection, this embodiment also supports anomaly detection in the current detection time, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using time relays to detect the current detection time, multiple detections of the current situation are achieved, enhancing the safety of escaping through windows during an accident.

[0011] In some optional embodiments, the temperature detection circuit of this invention further includes: a carbon monoxide detection switch, which includes: a carbon monoxide sensor and a carbon monoxide switch. The first end of the carbon monoxide sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the carbon monoxide switch. The second end of the carbon monoxide detection switch is connected to the negative terminal of each intermediate relay, and is used to conduct when the carbon monoxide sensor detects that the current carbon monoxide concentration exceeds the preset carbon monoxide concentration, thereby energizing each intermediate relay.

[0012] This embodiment uses a carbon monoxide detection switch to energize each intermediate relay when an abnormal carbon monoxide concentration is detected. In addition to supporting abnormal temperature detection, this embodiment also supports abnormal carbon monoxide concentration detection, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using a smoke detection switch to detect the carbon monoxide concentration in the current environment, multiple environmental detections are achieved, enhancing the safety of escaping through windows in the event of an accident.

[0013] In some optional embodiments, the temperature detection circuit of this utility model further includes: a smoke detection switch, which includes: a smoke sensor and a smoke switch. The first end of the smoke sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the smoke switch. The second end of the smoke switch is connected to the negative terminal of each intermediate relay, and it is used to conduct when the smoke sensor detects that the current smoke concentration exceeds the preset current smoke concentration, thereby energizing each intermediate relay.

[0014] This embodiment uses a smoke detection switch to energize each intermediate relay when an abnormal smoke concentration is detected in the current environment. In addition to supporting abnormal temperature detection, this embodiment also supports abnormal smoke concentration detection, facilitating timely and safe escape for trapped personnel in the event of a fire or vehicle accident. Therefore, by detecting the smoke concentration in the current environment through the smoke detection switch, multiple environmental detections are achieved, enhancing the safety of escaping through windows in the event of an accident.

[0015] In some optional embodiments, the temperature detection circuit of this invention allows the user to manually open a window corresponding to each drive motor.

[0016] In this embodiment, the temperature detection circuit not only allows users to manually open a window corresponding to each drive motor, but also supports automatic control of a window corresponding to each drive motor via a temperature detection switch.

[0017] Secondly, this utility model also provides a vehicle window control device, including: a protective cover, a partition, a circuit board, and a temperature detection circuit as described in the above embodiments.

[0018] The temperature detection circuit is mounted on the circuit board, and the partition is fixed inside the protective cover, dividing the inside of the protective cover into upper and lower spaces. The circuit board is fixedly connected to the upper surface of the partition.

[0019] The window control device in this embodiment is equipped with a temperature detection circuit. During vehicle operation, it can predict whether the current ambient temperature inside the vehicle is abnormal. When the ambient temperature inside the vehicle is determined to be abnormal, the temperature detection switch replaces the traditional carbon monoxide detection switch or smoke detection switch. Before a vehicle spontaneous combustion accident, the window is opened by detecting the temperature. This allows for early prediction of potential dangers and preventative measures, rather than passively taking action after an accident has already occurred, which would prevent timely assistance to trapped personnel to escape danger.

[0020] In some alternative implementations, a collision detection switch is also provided on the circuit board. The collision detection switch includes a collision sensor and a collision switch. The first end of the collision sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the collision switch. The second end of the collision switch is connected to the negative terminal of each intermediate relay. It is used to conduct when the collision sensor detects that the impact force of the current vehicle exceeds the preset impact force, thereby energizing each intermediate relay.

[0021] This embodiment uses a collision detection switch to energize each intermediate relay when an abnormal impact force of the current vehicle is detected. In addition to supporting abnormal temperature detection, this embodiment also supports current vehicle impact force detection, facilitating timely and safe escape for trapped personnel in the event of a fire or vehicle malfunction. Therefore, by detecting the current vehicle impact force through the collision detection switch, multiple detections of the current situation are achieved, enhancing the safety of escaping through open windows during an accident.

[0022] In some alternative implementations, a water level detection switch is also provided on the circuit board. The water level detection switch includes a water level sensor and a water level switch. The first end of the water level sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the water level switch. The water level switch has its second terminal connected to the negative terminal of each intermediate relay. It is used to turn on when the water level sensor detects that the current water level exceeds the preset water level, thereby energizing each intermediate relay.

[0023] This embodiment uses a water level detection switch to energize each intermediate relay when an abnormal water level is detected. In addition to supporting abnormal temperature detection, this embodiment also supports abnormal water level detection, facilitating safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using the water level detection switch to detect the current water level, multiple detection methods are implemented, enhancing the safety of escaping through windows during an accident.

[0024] In some alternative implementations, an alarm is also provided on the circuit board, which is connected to various sensors on the temperature detection circuit and various sensors on the circuit board, and is used to generate an alarm signal when the detection parameters are abnormal.

[0025] In this embodiment, an alarm is set up so that when various sensors detect abnormal parameters, a snap signal is generated, which helps rescuers to find the trapped person in time. Attached Figure Description

Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This embodiment provides a temperature detection circuit, such as Figure 1 As shown, it includes: a battery 11, a temperature detection switch 12, a lift assembly switch 13, multiple drive motors 14 and at least one intermediate relay 15, wherein each drive motor 14 is connected to an intermediate relay 15, and each drive motor 14 drives one window to open.

[0030] The battery may include, but is not limited to, lead-acid batteries and nickel-metal hydride batteries, etc., and is used to power the temperature detection circuit.

[0031] Currently, in situations where windows cannot be opened due to fire or vehicle accidents, smoke detection switches control window opening based on smoke levels or carbon monoxide detection switches based on carbon monoxide concentration. However, when smoke or carbon monoxide concentrations are high, opening the windows can easily trigger the fire to spread, exacerbating the fire. Similarly, in the event of a spontaneous combustion, the window opening circuit may be interrupted, preventing the windows from being opened further and hindering the timely escape of occupants.

[0032] Therefore, in this embodiment, the temperature detection switch, based on the real-time temperature detection results, works in conjunction with at least one intermediate relay, the lift assembly switch, and multiple drive motors to control each drive motor to open a window. This allows the windows to be opened in advance, either before a fire or before a vehicle spontaneously combusts, preventing the accident from worsening and preventing more people from escaping danger.

[0033] The window lift assembly switch is powered by a battery to control the drive motor, which in turn drives the lift to move up and down, thereby raising and lowering the glass installed on the window.

[0034] The number of intermediate relays in this embodiment may be one or more. For example... Figure 2 The diagram shown is the electrical connection diagram of the temperature detection circuit in this embodiment. Figure 2 In this embodiment, there are six intermediate relays 15, five of which correspond to one drive motor 14, and one intermediate relay 15 corresponds to the time relay 17 described below. Figure 2 It also includes: other types of detection switches 19.

[0035] exist Figure 1 In the middle, the temperature detection switch 12 has its first end connected to the negative terminal of the battery 11 and its second end connected to the negative terminal of each intermediate relay 15. It is used to energize each intermediate relay when the current ambient temperature is determined to be abnormal.

[0036] In some specific implementation methods, such as Figure 3 As shown, the temperature detection switch 12 includes a temperature sensor 121 and a temperature switch 122. The first terminal of the temperature sensor 121 is connected to the negative terminal of the battery 11, and its second terminal is connected to the first terminal of the temperature switch 122. The second terminal of the temperature switch 122 is connected to the negative terminal of each intermediate relay 15, and is used to activate each intermediate relay 15 when the temperature sensor 121 detects that the current ambient temperature exceeds a preset ambient temperature.

[0037] The current ambient temperature can be the ambient temperature of the environment in which the window is located, while the preset ambient temperature is the critical temperature that triggers a dangerous accident. For example, if the preset ambient temperature is 70℃ and the current ambient temperature is 80℃, this indicates an abnormal ambient temperature, causing the temperature switch to activate, which in turn energizes each intermediate relay. After each intermediate relay is energized, the lift assembly switch controls each drive motor to open the corresponding window.

[0038] Therefore, this embodiment replaces the traditional carbon monoxide detection switch or smoke detection switch with a temperature detection switch. Before a fire or vehicle spontaneous combustion accident occurs, the window is opened by detecting the temperature, which can help to predict the danger in advance and prevent it from happening. This avoids the situation where measures are taken passively after an accident has occurred, and the trapped people cannot be assisted in time to escape danger.

[0039] In Figure 1, each intermediate relay 15 has its common terminal connected to the negative terminal of the battery and its positive terminal connected to the positive terminal of the battery.

[0040] exist Figure 2 In the middle, the intermediate relay 15 includes: positive terminal 151, negative terminal 152, normally closed terminal 153, normally open terminal 154, and common terminal 155.

[0041] exist Figure 2 In this configuration, the common terminals of each intermediate relay 15 are connected together and then connected to the negative terminal of the battery 11. The negative terminals of each intermediate relay 15 are then connected together and then connected to the second terminal of the temperature detection switch 12. Figure 2 In this configuration, the normally open terminal 154 of each of the five intermediate relays 15 is connected to a drive motor 14, and the normally open terminal 154 of one intermediate relay 15 is connected to a time relay 17. The normally closed terminal 153 of each intermediate relay 15 is connected together and then connected to the negative output terminal of the lift assembly switch 13.

[0042] The reason why this embodiment uses multiple intermediate relays instead of a single intermediate relay is that if all the drive motors are connected in parallel to a single intermediate relay, a short circuit may occur when the user manually closes the window.

[0043] exist Figure 1 In the middle, the lifting assembly switch 13 has its positive input terminal connected to the positive terminal of the battery, its negative input terminal left floating, and its negative output terminal connected to the normally closed terminal of each intermediate relay.

[0044] In this embodiment, the negative terminal of the elevator assembly switch is left floating. When the current ambient temperature is determined to be normal, the negative terminal of each intermediate relay is not energized, and its common terminal and normally closed terminal are directly connected. When the current ambient temperature is determined to be abnormal, the negative terminal of each intermediate relay is energized, and its normally closed terminal is not energized. At this time, its common terminal and normally open terminal are directly connected.

[0045] In this embodiment, the negative terminal of the window lift assembly switch is left unconnected to prevent a short circuit caused by a user suddenly opening the window manually, which could conflict with the automatic window opening.

[0046] Therefore, the temperature detection circuit in this embodiment not only allows users to manually open a window driven by each drive motor, but also allows automatic control of a window driven by each drive motor via a temperature detection switch.

[0047] exist Figure 1 In this configuration, the negative terminal of each drive motor 14 is connected to the normally open terminal of each intermediate relay, and the positive terminal is connected to the positive output terminal of the lift assembly switch 13. This is used to drive the corresponding window to open after each intermediate relay is energized.

[0048] In this embodiment, each drive motor is used to drive multiple windows to rise and fall. When the temperature detection and control circuit in this embodiment is applied in a vehicle, Figure 1 In the middle, drive motor 14 is used to drive window a in the driver's cab to open; drive motor 14 is used to drive window b in the passenger's cab to open; drive motor 14 is used to drive window c on the left side of the rear row to open; drive motor 14 is used to drive window d on the right side of the rear row to open; drive motor e is used to drive the sunroof in the middle to open.

[0049] In some specific implementations, the temperature detection circuit in this embodiment, such as Figure 4 As shown, it also includes: a solenoid valve switch 16, a binding device 18, and a time relay 17, wherein the time relay 17 is connected to an intermediate relay 15.

[0050] The solenoid valve switch 16 has its positive terminal connected to the positive terminal of each drive motor 14, and its negative terminal connected to the negative terminal of the bonding device 18 and the time relay 17. Binding device 18 is used to bind the object to be bound, ensuring the safety of the object to be bound.

[0051] The restraint device here is usually a seat belt, and the restraint object can be a person.

[0052] The time relay 17 has its positive terminal connected to the positive terminal of each drive motor 14 and its negative terminal connected to the normally open terminal of its corresponding intermediate relay 15. When each intermediate relay 15 is energized, if the current detection time is greater than the preset detection time, the solenoid valve switch 16 is energized, thereby causing the binding device 18 to be opened.

[0053] This invention energizes each intermediate relay when an anomaly is detected in the current detection time. In addition to supporting temperature anomaly detection, this embodiment also supports anomaly detection in the current detection time, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using time relays to detect the current detection time, multiple detections of the current situation are achieved, enhancing the safety of escaping through windows during an accident.

[0054] In some optional implementations, the temperature detection circuit in this embodiment further includes a carbon monoxide detection switch, which includes a carbon monoxide sensor and a carbon monoxide switch. The first terminal of the carbon monoxide sensor is connected to the negative terminal of the battery, and its second terminal is connected to the first terminal of the carbon monoxide switch. The second terminal of the carbon monoxide detection switch is connected to the negative terminal of each intermediate relay, and is used to conduct when the carbon monoxide sensor detects that the current carbon monoxide concentration exceeds a preset carbon monoxide concentration, thereby energizing each intermediate relay.

[0055] The carbon monoxide detection switch energizes each intermediate relay when an abnormal carbon monoxide concentration is detected. This embodiment supports not only abnormal temperature detection but also abnormal carbon monoxide concentration detection, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using the smoke detection switch to detect the carbon monoxide concentration in the current environment, multiple environmental detections are achieved, enhancing the safety of escaping through windows in the event of an accident.

[0056] In some optional implementations, the temperature detection circuit in this embodiment further includes: a smoke detection switch, which includes a smoke sensor and a smoke switch. The first end of the smoke sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the smoke switch. The second end of the smoke switch is connected to the negative terminal of each intermediate relay, and it is used to conduct when the smoke sensor detects that the current smoke concentration exceeds the preset current smoke concentration, thereby energizing each intermediate relay.

[0057] The smoke detection switch energizes each intermediate relay when an abnormal smoke concentration is detected in the current environment. This embodiment supports both abnormal temperature detection and abnormal smoke concentration detection, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by detecting the smoke concentration in the current environment through the smoke detection switch, multiple environmental detections are achieved, enhancing the safety of escaping through windows in the event of an accident.

[0058] This embodiment also provides a vehicle window control device, such as... Figure 5 As shown, it includes: a protective cover 51, a partition 52, a circuit board 53, and a temperature detection circuit 54 in the above embodiment. The temperature detection circuit is disposed on the circuit board 53. The partition 52 is fixed inside the protective cover, dividing the inside of the protective cover into upper and lower spaces. The circuit board 43 is fixedly connected to the upper surface of the partition 52.

[0059] In other words, this embodiment applies the temperature detection circuit described in the previous embodiment to a vehicle, thus forming a window control device. During vehicle operation, a smoke detection switch controls the window opening based on the smoke level of a fire, or a carbon monoxide detection switch controls the window opening based on the carbon monoxide concentration, preventing situations where occupants cannot escape through the windows in the event of a fire. However, in the event of a fire, the window opening circuit may experience a circuit break, preventing the window from being opened further and thus preventing occupants from escaping danger in time.

[0060] Therefore, the window control device in this embodiment is equipped with a temperature detection circuit, which can predict in advance whether the current ambient temperature inside the vehicle is abnormal during vehicle operation. When the ambient temperature inside the vehicle is determined to be abnormal, the temperature detection switch replaces the traditional carbon monoxide detection switch or smoke detection switch. Before a vehicle spontaneous combustion accident, the window is opened by detecting the temperature, which can realize the early prediction of danger and prevent problems before they occur. This avoids the situation where passive measures are taken after an accident has already occurred, which may prevent timely assistance to trapped people to escape danger.

[0061] In some specific implementations, a collision detection switch is also provided on the circuit board. The collision detection switch includes a collision sensor and a collision switch. The first end of the collision sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the collision switch. The second end of the collision switch is connected to the negative terminal of each intermediate relay. It is used to conduct when the collision sensor detects that the impact force of the current vehicle exceeds the preset impact force, thereby energizing each intermediate relay.

[0062] Specifically, the collision detection switch can be a silicon controlled rectifier (SCR) structure, which can conduct continuously and maintain permanent power. The collision sensor can be a mechanical collision sensor such as a rolling ball, roller, or eccentric ball type, which uses internal mechanical structures to achieve circuit switching; its operating state depends on the vehicle's acceleration during the collision. Collision sensors can also be electronic collision sensors such as roller and eccentric ball types, which detect the intensity of the collision through electronic signals. Compared to mechanical sensors, electronic sensors have higher sensitivity and accuracy.

[0063] The collision detection switch energizes each intermediate relay when an abnormal impact force of the current vehicle is detected. This embodiment supports not only abnormal temperature detection but also current vehicle impact force detection, facilitating timely and safe escape for trapped individuals in the event of a fire or vehicle malfunction. Therefore, by detecting the current vehicle impact force through the collision detection switch, multiple detections of the current situation are achieved, enhancing the safety of escaping through open windows during an accident.

[0064] In some specific implementations, a water level detection switch is also provided on the circuit board. The water level detection switch includes a water level sensor and a water level switch. The first end of the water level sensor is connected to the negative terminal of the battery, and its second end is connected to the first end of the water level switch. The second end of the water level switch is connected to the negative terminal of each intermediate relay. It is used to conduct when the water level sensor detects that the current water level exceeds the preset water level, thereby energizing each intermediate relay.

[0065] The water level detection switch is used to energize each intermediate relay when an abnormal water level is detected. This embodiment supports not only abnormal temperature detection but also abnormal water level detection, facilitating safe escape for trapped individuals in the event of a fire or vehicle accident. Therefore, by using the water level detection switch to detect the current water level, multiple detections of the current water level are achieved, enhancing the safety of escaping through windows in the event of an accident.

[0066] In some specific implementations, an alarm is also provided on the circuit board, which is connected to various sensors on the temperature detection circuit and various sensors on the circuit board, and is used to generate an alarm signal when the detection parameters are abnormal.

[0067] The alarm device in this embodiment is designed to generate an alarm signal when various sensors detect abnormal parameters, so that rescuers can find trapped personnel in a timely manner.
