Description

Technical Field

[0001] This utility model relates to the field of fuel supply technology, and in particular to an output structure for a fuel leak alarm device. Background Technology

[0002] A car's fuel tank is a sealed container that stores fuel (gasoline or diesel) to provide a continuous and stable fuel supply to the engine, ensuring that the stored gasoline or diesel fuel provides the vehicle's range. It is one of the core components of a car's fuel system.

[0003] Traditional fuel tanks are mostly single-layered structures, making it difficult for drivers to detect leaks in time if a leak occurs while the car is in motion. This not only leads to fuel waste but also causes environmental pollution and even the risk of fire. Utility Model Content

[0004] To address the technical problem that traditional fuel tanks are mostly single-layer structures, making it difficult to detect leaks in a timely manner, which may lead to fuel waste, environmental pollution, or even fire risks, this utility model provides an output structure device for a fuel leak alarm device.

[0005] This utility model is achieved using the following technical solution: an output structure device for a fuel leak alarm device, comprising an outer fuel tank and an inner fuel tank, wherein the outer side of the inner fuel tank is fixedly connected to two horizontally parallel inner sides and one vertically parallel inner side of the outer fuel tank, a gap layer is provided between the inner fuel tank and the outer fuel tank, a sensing component for preliminary alarm of fuel leak is provided at the bottom outer side of the gap layer, a monitoring component for further alarm of the vehicle is provided at the middle and high outer side of the gap layer, and a filler neck is provided at the top of the inner fuel tank.

[0006] The above technical solution avoids fuel leakage to the outside caused by tank damage, thus preventing resource waste and environmental pollution. The gap layer between the outer and inner tanks collects leaked fuel and allows the driver to be notified of fuel leaks in time and to repair them through the sensing and monitoring components installed in the gap layer.

[0007] As a further improvement to the above solution, the sensing component includes a sensor fixed to the bottom of the outer side of the outer oil tank, the monitoring end of the sensor extending into the gap layer and fixed to a sensing plate, and a float ball disposed between the sensing plate and the gap layer.

[0008] With the above technical solution, the float in the sensing component will gradually rise in the gap layer as the amount of leaked oil increases. When the float touches the sensing plate, the sensor fixed to the outside of the outer fuel tank will transmit the oil leakage information to the controller, so that the driver can have a preliminary understanding of the fuel tank leakage information and make adjustments to the vehicle.

[0009] As a further improvement to the above solution, the monitoring component includes an alarm fixed to the middle and high end of the outer side of the outer fuel tank. The monitoring end of the alarm extends to the gap layer and is fixed to an alarm plate. A controller is fixed to the top of the outer side of the outer fuel tank. An LED warning light and a buzzer are fixed to the top of the outer fuel tank.

[0010] With the above technical solution, when the leaking oil in the interstitial layer rises to the middle to high position, it will trigger the alarm to transmit the interstitial layer containment critical point to the controller. At this time, the controller will transmit information to the LED warning light and buzzer fixed to the top of the outer fuel tank so that the driver can quickly drain the interstitial layer full of oil and the fuel tank leaking oil.

[0011] As a further improvement to the above solution, the sensor, alarm, LED warning light and buzzer are all electrically connected to the controller.

[0012] With the above technical solution, when an initial alarm is triggered, the sensor located at the bottom of the outer side of the outer fuel tank will transmit fuel tank leakage information to the controller. The controller will then upload the fuel tank leakage information to the vehicle's infotainment system or the driver's mobile phone for notification. When the leakage triggers the alarm located at the middle and upper part of the interstitial layer, the alarm will transmit information about the critical point of the interstitial layer's fuel capacity to the alarm. At this time, the alarm will directly trigger the LED warning light to flash and the buzzer to sound through the telecommunication connection, reminding the driver to take timely action.

[0013] As a further improvement to the above scheme, the bottom of the inner oil tank is inclined towards the intermittent layer, and the inclination angle of the bottom of the inner oil tank is 2 to 5 degrees.

[0014] The above technical solution involves tilting the bottom of the inner oil tank at an angle of 2 to 5 degrees. The inner oil tank is fixed to the two horizontally parallel inner sides and one vertically parallel inner side of the outer oil tank, so that when the inner oil tank leaks oil, it can easily collect in the gap layer.

[0015] As a further improvement to the above solution, a fuel drain hole is provided at the bottom end of the gap layer, and a sealing plug is provided inside the fuel drain hole.

[0016] With the above technical solution, the driver or maintenance personnel can drain the leaking fuel through the drain hole and inspect the inner fuel tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention avoids direct fuel leakage to the outside due to tank damage by using a double-layer design of an outer and inner fuel tank, thus preventing resource waste and environmental pollution. The gap layer between the outer and inner fuel tanks serves two purposes: firstly, it collects leaked fuel, and secondly, the sensing and monitoring components installed in the gap layer allow the driver to promptly detect fuel leaks and perform repairs.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 This embodiment provides an output structure device for a fuel leak alarm device, including an outer fuel tank 1 and an inner fuel tank 2. The outer side of the inner fuel tank 2 is fixed to two horizontally parallel inner sides and one vertically parallel inner side of the outer fuel tank 1. A gap layer 3 is provided between the inner fuel tank 2 and the outer fuel tank 1. A sensing component for preliminary alarm of fuel leak is provided at the bottom outer side of the gap layer 3. A monitoring component for further alarm of the vehicle is provided at the middle and high outer side of the gap layer 3. A filler neck 4 is provided at the top of the inner fuel tank 2.

[0026] Combination Figure 2The sensing assembly includes a sensor 5 fixed to the bottom of the outer side of the outer fuel tank 1. The monitoring end of the sensor 5 extends into the gap layer 3 and is fixed to a sensing plate 6. A float 7 is disposed between the sensing plate 6 and the gap layer 3. The monitoring assembly includes an alarm 8 fixed to the upper middle part of the outer side of the outer fuel tank 1. The monitoring end of the alarm 8 extends into the gap layer 3 and is fixed to an alarm plate 9. A controller 10 is fixed to the top of the outer side of the outer fuel tank 1. An LED warning light 11 and a buzzer 12 are fixed to the top of the outer fuel tank 1. The sensor 5, alarm 8, LED warning light 11, and buzzer 12 are all electrically connected to the controller 10. During the initial alarm, the float 7 in the sensing assembly gradually rises in the gap layer 3 as the amount of oil leaking from the inner fuel tank 2 increases. When the float 7 touches the sensing plate 6, the float 7 fixed to the outer side of the outer fuel tank 1 is activated. Sensor 5 transmits oil leak information to controller 10. Controller 10 then uploads the oil leak information to the vehicle system or the driver's mobile phone for notification. Due to environmental factors, such as in a highway tunnel, even if the driver receives an initial alarm for oil leak, they cannot immediately stop to inspect the oil tank. Therefore, the leaking oil in the gap layer 3 will continue to rise until it reaches a mid-to-high position, giving the driver some time to prepare. At the same time, the leak inside the gap layer 3 will also put pressure on the alarm plate 9, causing the alarm 8 to transmit the critical point of the gap layer to controller 10. At this time, controller 10 will transmit information to the LED warning light 11 and buzzer 12 fixed to the top of the outer oil tank 1 so that the driver can drain the oil from the gap layer and resolve the oil leak problem in time.

[0027] Combination Figures 2-3 The bottom of the inner fuel tank 2 is inclined towards the interstitial layer, and the inclination angle of the bottom of the inner fuel tank 2 is 2 to 5 degrees. The bottom of the interstitial layer 3 is provided with a drain hole 13 for leaking fuel, and a sealing plug 14 is provided inside the drain hole 13. The bottom of the inner fuel tank 2 is inclined at 2 to 5 degrees. At the same time, the inner fuel tank 2 is fixed to the two horizontal parallel inner sides and one vertical parallel inner side of the outer fuel tank 1, so that when the inner fuel tank 2 leaks, it can easily collect into the interstitial layer 3. The driver or maintenance personnel can drain the leaking fuel through the drain hole 13 and repair the inner fuel tank.

[0028] The implementation principle of the output structure device for a fuel leak alarm device in this application embodiment is as follows:

[0029] When the driver is driving the vehicle and the inner oil tank 2 leaks oil, because the bottom of the inner oil tank 2 is set with an inclined surface between 2 and 5 degrees, and the outer side of the inner oil tank 2 is fixed to the two horizontal parallel inner sides and one vertical parallel inner side of the outer oil tank 1, the oil leaking from the inner oil tank 2 will flow directly into the gap layer 3.

[0030] When the float 7 touches the sensor plate 6, the sensor 5 fixed to the outside of the outer fuel tank 1 will transmit the oil leakage information to the controller 10. The controller 10 will upload the fuel tank oil leakage information to the vehicle system or the driver's mobile phone for notification. Due to the influence of the driving environment, such as in a high-speed tunnel, even if the driver receives the initial alarm of the oil leakage information, he cannot stop immediately to inspect the fuel tank. Therefore, the leaking oil in the gap layer 3 will continue to rise until it rises to the middle and high position, giving the driver some time to prepare. At the same time, the leakage inside the gap layer 3 will also put pressure on the alarm plate 9, causing the alarm 8 to transmit the critical point of the interstitial layer to the controller 10. At this time, the controller 10 will transmit information to the LED warning light 11 and the buzzer 12 fixed to the top of the outer fuel tank 1 so that the driver can drain the interstitial layer full of oil in time and solve the fuel tank oil leakage problem.

[0031] The driver or maintenance personnel can simply remove the sealing plug 14 inside the drain hole 13 at the bottom of the gap layer 3 to complete the recovery of leaked oil and the maintenance of the inner oil tank 2.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
