Description

Technical Field

[0001] This utility model relates to the technical field of urea tank equipment, specifically a micro-truck 12L urea tank assembly. Background Technology

[0002] The urea tank is a key storage component in the selective catalytic reduction system. It is mainly used to hold automotive urea solution. When the diesel engine is running, the solution in the urea tank is injected into the engine's exhaust system in a metered manner. Under the action of high-temperature exhaust, the urea solution hydrolyzes to generate ammonia. Subsequently, the ammonia reacts chemically with nitrogen oxides in the exhaust gas in the SCR catalytic converter, reducing them into harmless nitrogen and water. This significantly reduces the emission of nitrogen oxides, the main pollutant in diesel vehicle exhaust, and meets increasingly stringent environmental regulations. In terms of installation compatibility, existing urea tanks are usually installed using fixed brackets or simple cable ties. This rigid connection method is difficult to adjust flexibly to adapt to the subtle differences in chassis structure of different vehicle models, resulting in poor universality. When some mounting brackets have dimensional errors during the manufacturing process, it can easily cause the urea tank to tilt or shake slightly after installation, affecting its performance.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1 to 4 In this embodiment of the utility model, the 12L urea tank assembly includes: a urea tank 1 and an adjustment and connection assembly 5. The urea tank 1 serves as the main container, and an injection pipe 2 is fixedly inserted at an angle on its top. A tank cover 3 is connected to the top of the injection pipe 2 by a threaded rotation. An observation port 4 is opened directly above the urea tank 1. A sealing cover is also connected to the top of the observation port 4 by a threaded rotation. In order to improve the convenience of injection and the sealing performance of the observation port and prevent urea leakage, a rubber sealing ring is provided at the connection between the sealing cover and the observation port 4.

[0015] A liquid level observation window 6 is provided on the side of the urea tank 1. The liquid level observation window 6 is preferably made of tempered glass to have good corrosion resistance and strength. In order to facilitate accurate observation of the remaining amount of urea solution in the tank, a scale line is provided on the outside of the liquid level observation window 6. The minimum division of the scale line is 0.5 liters, and it is preferably made by laser engraving process to ensure that the scale is clear and durable. A discharge chamber 7 is fixedly connected to the bottom of the urea tank 1, and a discharge nozzle 8 for connecting the conveying pipeline is fixedly connected below the discharge chamber 7.

[0016] The adjusting connection assembly 5 is located on the side of the urea tank 1 away from the injection pipe 2. Its core function is to achieve a fixed connection between the urea tank assembly and peripherals of different sizes or specifications, such as vehicle frames, thereby enhancing the product's versatility and installation adaptability. Specifically, the adjusting connection assembly 5 includes a base frame 51 fixedly connected to the side of the urea tank 1. A protruding plate 52 is fixedly connected to the side of the base frame 51. A groove is formed on the surface of the protruding plate 52. A sliding adjusting member 53 is slidably connected within this groove via a sliding rod. Preferably, both ends of the sliding rod are fixedly connected to the sliding adjusting member 53 via nuts. A connecting plate is fixedly connected to the side of the sliding adjusting member 53. 54. The surface of the connecting plate 54 is reserved with mounting holes for connecting with external equipment. In order to adapt to different installation strength requirements, the mounting holes reserved on the surface of the connecting plate 54 are usually two to four, and are symmetrically distributed on both sides of the connecting plate 54. In order to achieve positioning of the sliding adjustment member 53 after movement, multiple positioning holes 56 are opened on the surface of the base frame 51. At the same time, positioning pins 55 are movably inserted on both sides of the sliding adjustment member 53 near the edge. When the sliding adjustment member 53 moves to the appropriate position, the positioning pins 55 pass through the sliding adjustment member 53 and insert the end into the corresponding positioning hole 56, thereby effectively restricting the movement of the sliding adjustment member 53 and ensuring the stability of the connection.

[0017] The working principle of this utility model is as follows: Urea solution is added to urea tank 1 by unscrewing the tank cover 3 through the inclined injection pipe 2. During the filling, the observation port 4 located on the top of the tank and its sealing cover can be used for inspection and maintenance. Combined with the liquid level observation window 6 on the side and its laser-engraved scale lines, the liquid level and quality of urea in the tank can be clearly monitored to ensure that the solution is sufficient and there are no abnormalities. Urea tank 1 itself is made of corrosion-resistant materials such as high-density polyethylene, which can effectively store urea solution. Once the vehicle is started and the urea system's operating conditions are met, the system enters the preparation phase. If the ambient temperature is low, the heating device integrated in the urea tank 1 will be activated to thaw and keep the urea solution warm, preventing it from solidifying. At the same time, the discharge chamber 7 and discharge nozzle 8 serve as the outlet for transporting the urea solution to the system, connecting to the subsequent conveying pipeline and injection device. The urea tank assembly is stably installed on the vehicle via its key adjustment and connection component 5, which is fixed to the tank body via a base frame 51. The connecting plate 54 is used to connect to the vehicle frame. The position of the connecting plate 54 can be adjusted by moving the sliding adjustment component 53 within the groove of the convex plate 52. Once the position is properly adjusted, the locating pin 55 is inserted into the sliding adjustment component 53 and passed through the corresponding locating hole 56 on the base frame 51 to securely lock the sliding adjustment component 53. This adapts to the different installation space of different vehicle models and ensures that the urea tank 1 will not loosen due to vibration during vehicle operation.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
