Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile water trough component. Background Art
[0002] Automobile gutters play a crucial role in the vehicle's body system, serving as a key component for ensuring the smooth function of drainage. Their core function is to effectively direct rainwater from the vehicle body, draining it smoothly outside the vehicle, preventing it from seeping into the interior and ensuring a dry and comfortable interior environment. Gutters also help prevent rainwater from penetrating the vehicle's sheet metal structure, preventing premature rust from prolonged exposure to moisture, and ensuring durability and safety. Depending on their location, automobile gutters can be categorized as front windshield gutters, sunroof gutters, door gutters, and trunk gutters. Front windshield gutters primarily direct rainwater from the windshield, preventing it from flowing down the glass and into the vehicle, obstructing the driver's vision. Sunroof gutters drain rainwater from the sunroof, preventing it from accumulating around the edges and causing leakage. Door gutters direct rainwater from the doors, preventing it from entering the vehicle through the door gaps. The trunk gutter ensures that rainwater can drain smoothly from the trunk area, preventing it from accumulating inside. Therefore, the layout of a vehicle's gutter is crucial for ensuring drainage and preventing rust. Through proper design and layout, the gutter effectively directs rainwater, ensuring a dry interior and maintaining structural integrity, thus creating a comfortable and safe driving environment for the driver and passengers.
[0003] The windshield gutter plays a crucial role in a car's water flow system. Located below the vehicle's windshield wipers, its primary function is to prevent rainwater from obstructing the driver's vision and flowing down the windshield into the engine compartment. Drains on either side of the gutter effectively direct rainwater flowing down the windshield, preventing it from flowing into the engine compartment and ensuring a clear view for the driver. To prevent fallen leaves, dust, and other large particles from clogging the water flow path, the windshield gutter requires a filter element. This effectively filters fallen leaves, dust, and other large particles from the water flow, preventing blockage and resulting water flow. However, in actual use, the filtering effect of the filter element is often unsatisfactory. In heavy rainfall, the filtration rate of the water cannot keep up with the flow rate of the water while the car is driving, resulting in water overflowing into the engine compartment. This rainwater then contacts various components within the engine compartment, causing corrosion and oxidation, which in turn damages the vehicle components and reduces the overall service life of the vehicle. Furthermore, for cars that are used for a long time, if the gutter is not cleaned of debris and dirt in a timely manner, the sieved fallen leaves, dust, and other large particles of impurities will cover the filter assembly, causing blockage. However, it is often difficult for drivers to understand the blockage information of the filter assembly, resulting in an inability to take timely measures, causing rainwater to overflow into the car's engine compartment, affecting the car's service life. Therefore, there is room for improvement in the filtering method of the gutter assembly to facilitate the discharge of water and promptly remind the driver to clean the gutter of debris and dirt, so as to ensure that the driver has a safe and comfortable driving environment in all weather conditions.

[0022] like Figures 1 to 7 As shown, a car water flow channel assembly includes a trough body 1 with an opening at the top, and two through holes 2 are respectively opened at the bottom of the trough body 1. The two through holes 2 are respectively set with a filter cartridge 3 with an opening at the top. The filter cartridge 3 is provided with a filter core 4 with an opening at the bottom. The bottom of the filter core 4 is embedded in the bottom of the filter cartridge 3. The filter core 4 and the filter cartridge 3 both adopt a conical barrel structure. The diameter of the filter core 4 gradually increases from top to bottom, and the diameter of the filter cartridge 3 gradually decreases from top to bottom. The filter cartridge 3 and the filter core 4 are respectively provided with a plurality of sieve holes 5. Several sieve holes 5 are evenly arranged on the filter cartridge 3 or filter element 4. A float 6 made of lightweight material is located above the filter element 4. A fixing rod 7 is located on the bottom surface of the float 6. A sleeve hole 8 is formed on the top plate of the filter element 4, which is mounted on the fixing rod 7. A fixing block 9 is located at the top of the inner cavity of the filter element 4. The fixing rod 7 is connected to the float 6 and the fixing block 9 on both sides. A pressure probe 10 is located above the float 6, with the pressure-sensing end of the pressure probe 10 facing the float 6. The pressure probe 10 is mounted on the filter element 4 through the bracket, and the float 6 is located within the bracket. The filter element 4 is used to increase the filtration space of the filter cartridge 3, thereby improving the filtration capacity of the present invention and enabling the water to be filtered quickly. By designing both the filter cartridge 3 and the filter element 4 into a tapered structure, the inner cavity cross-section of the filter cartridge 3 gradually decreases from top to bottom, thereby gradually increasing the flow rate of the water in the filter cartridge 3 from top to bottom, so that the water can be discharged from the sieve holes 5. If fallen leaves, dust or other large particles of impurities clog the filter cartridge 3 and the filter element 4 or the flow rate of the water exceeds the filtration rate of the water, the accumulated water in the filter cartridge 3 will drive the float 6 to float upward, thereby driving the fixing rod 7 and the fixing block 9 to move upward, so that the float 6 squeezes the pressure probe 10, so as to facilitate the feedback of the information of excessive water inventory to the car's central control through the pressure probe 10, thereby facilitating timely reminder to clean the tank 1.
[0023] In this embodiment, two clamping holes 11 are provided at the bottom of the trough body 1, and the two clamping holes 11 are respectively located above the two through holes 2. The two through holes 2 are respectively connected to the inner cavity of the trough body 1 through the two clamping holes 11. The aperture of the clamping hole 11 is not less than the aperture of the through hole 2. A sealing ring 12 made of elastic material is interference-fitted inside the clamping hole 11, and a fixing ring 13 is interference-fitted inside the sealing ring 12. The fixing ring 13 is sleeved on the top of the filter cartridge 3. The fixing ring 13 and the filter cartridge 3 are an integrated structure. By conveniently loading and unloading the filter cartridge 3, it is convenient to clean the impurities screened out in the filter cartridge 3. The sealing ring 12 is used to seal the gap between the fixing ring 13 and the clamping hole 11 to prevent water from flowing into the through hole 2.
[0024] Specifically, the top surface of the fixing ring 13 and the top surface of the filter cartridge 3 are located on the same plane, and the top surface of the filter cartridge 3 and the top surface of the sealing ring 12 are both located in the middle of the clamping hole 11, so that the water flowing into the clamping hole 11 can enter the filter cartridge 3. The top of the clamping hole 11 adopts a conical circular hole structure, and the aperture of the top of the clamping hole 11 gradually decreases from top to bottom, thereby facilitating the guidance of the water on both sides of the tank body 1 into the filter cartridge 3. In addition, because the filter cartridge 3 and the filter core 4 are both designed with a conical structure, after the water flows into the inner cavity of the filter cartridge 3, the water will squeeze the filter cartridge 3 and the filter core 4, causing the filter cartridge 3 and the filter core 4 to have a downward movement tendency, that is, causing the fixing ring 13 to move toward the through hole 2, thereby pressing the fixing ring 13 against the through hole 2, thereby reducing the shaking of the filter cartridge 3 and improving the assembly stability of the filter cartridge 3.
[0025] Please refer again Figure 4 The inner cavity of the trough body 1 adopts an arc-shaped structure, and the inner cavity height of the trough body 1 gradually decreases along the middle of the trough body 1 toward the end of the trough body 1, thereby guiding the water flowing into the trough body 1 to be transported toward the through hole 2; a plurality of blocks 14 are arranged in the trough body 1 between the two through holes 2, and the plurality of blocks 14 are installed at equal intervals on the bottom plate of the trough body 1, and the height of the blocks 14 gradually decreases along the middle of the trough body 1 toward the end of the trough body 1, thereby using the blocks 14 to block impurities such as sand in the flowing water, so as to slow down the clogging of the filter cartridge 3.
[0026] Please refer again Figure 7A fixed pipe 15 is provided below the through hole 2. The top end of the fixed pipe 15 is mounted on the bottom surface of the tank body 1. A drain pipe 16 is threadedly mounted on the internal thread of the fixed pipe 15. The lower and middle portion of the filter cartridge 3 is located within the drain pipe 16. The drain pipe 16 communicates with the inner cavity of the tank body 1 through the filter cartridge 3 or the filter element 4. A one-way valve 17 is provided at the bottom of the drain pipe 16. The input end of the one-way valve 17 is mounted on the bottom end of the drain pipe 16. The drain pipe 16 is used to discharge the water filtered by the filter cartridge 3 or the filter element 4. The one-way valve 17 is used to prevent the water from flowing back, so that the water can be treated.
[0027] Specifically, the inner cavity diameter of the drain pipe 16 is not less than the aperture of the through hole 2, so as to facilitate the water flowing into the filter cartridge 3 to enter the drain pipe 16. A sealing ring 18 made of elastic material is provided between the drain pipe 16 and the trough body 1. The sealing ring 18 is interference fit in the fixed tube 15. The sealing ring 18 is squeezed into the trough body 1 through the drain pipe 16, thereby sealing the gap between the drain pipe 16 and the trough body 1 and the fixed tube 15 to prevent water from leaking from the gap between the drain pipe 16 and the fixed tube 15.
[0028] In this embodiment, the length of the fixing block 9 is not less than the inner diameter of the sleeve hole 8, thereby restricting the fixing rod 7 and preventing the fixing rod 7 from passing through the sleeve hole 8. The float 6 is located at the top of the inner cavity of the filter cartridge 3, so that after the top surface of the accumulated water in the filter cartridge 3 reaches the top of the filter cartridge 3, the accumulated water can drive the float 6 to rise. The float 6 adopts a stepped round block structure, and the top diameter of the float 6 is not less than the bottom diameter of the float 6, so that it is convenient for the water to drive the float 6 to float up.
[0029] The assembly method of this product is as follows: Figures 1 to 7As shown, first, trough 1 is assembled below the vehicle's front windshield wiper, ensuring that trough 1 is located between the vehicle's engine compartment and the front windshield, allowing water flowing down the windshield to flow into trough 1. Then, sealing ring 18 is placed into fixing tube 15. Drain pipe 16, equipped with a one-way valve 17, is tightened and inserted into fixing tube 15. Drain pipe 16 is connected to the vehicle's water flow path, allowing water flowing out of drain pipe 16 to be discharged through the vehicle's water flow path to prevent contact with the vehicle body. Next, pressure probe 10 is connected to the vehicle's central control panel using wires, and sealing ring 12 is interference fit onto fixing ring 13. Fixing ring 13, equipped with sealing ring 12, is then assembled into retaining hole 11, allowing filter cartridge 3 and filter element 4 to fit into through-hole 2, thus completing the assembly of this product. It should be noted that when cleaning this product, first use a high-pressure water gun to clean the tank body 1, so that the debris and dirt in the tank body 1 are carried out into the inner cavity of the filter cartridge 3 by the water flow. Then, by pulling the filter cartridge 3 and the fixing ring 13, the filter cartridge 3 and the filter core 4 are removed, and the filter cartridge 3 and the filter core 4 are cleaned with water to remove the debris and dirt on the filter cartridge 3 and the filter core 4.
[0030] In this embodiment, the filter element 4 increases the filtration area, thereby improving filtration efficiency and enabling rapid filtration of flowing water. Furthermore, both the filter cartridge 3 and the filter element 4 are designed with a tapered structure, so that the inner cross-section of the filter cartridge 3 gradually decreases from top to bottom, thereby gradually increasing the flow rate of the water in the filter cartridge 3 from top to bottom, allowing the water to be discharged from the sieve holes 5. Furthermore, when fallen leaves, dust, and other large particles of impurities clog the filter cartridge 3 and the filter element 4, or when the flow rate of the water exceeds the filtration rate, the accumulated water in the filter cartridge 3 will drive the float 6 upward, causing it to press against the pressure probe 10. This facilitates feedback of excessive water levels to the vehicle's central control system via the pressure probe 10, thereby facilitating timely reminders to clean the tank 1.
[0031] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
