DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] A sealed water-guiding structure of a truck door system is closely related to the sealing of the window glass, the internal sealing of the door, and the sealing of the door and the white body, and is also related to the external and internal water flow paths of the door. The utility model provides the following technical solutions, which introduce the sealed water-guiding structure of the door system and the planned water flow path from the parts such as the external water cut 1, the window glass 3, the door inner panel 10, the lifter mounting plate 17, the waterproof membrane 18, the second sealing strip 12 and the door opening sealing strip 11.
[0031] like Figure 1-5As shown, the window glass is sealed with an outer water cut 1 and an inner water cut 2. The outer water cut 1 at the lower part of the window frame is composed of a cloak 4 and a bubble tube 5. The cloak 1 of the outer water cut 1 is interference fit with the window glass 3. This structure can not only make up for the manufacturing accuracy deviation, but also form an external water flow path for the window glass, that is, the water flow path schematic diagram 7, to guide the rainwater passing through the window glass 3 along the cloak 4 to prevent water from flowing into the door; the inner water cut is a bubble tube 6, and the bubble tube 6 is interference fit with the window glass 3 to prevent water from flowing into the door; the lower edge of the window glass 3 is polished and smooth, and the smooth lower edge makes it easy for water to form water droplets. Drip corners 8 are designed on the front and rear sides. The drip corners 8 should avoid the installation position of the window glass and the lifter, and can also guide the water flow. The water flows along the lower edge of the lathe glass to the drip corner, and drips from the drip corner to the inside of the door on both sides to avoid dripping on electrical components or other accessories.
[0032] like Figure 6-7 As shown, the door and the body in white are sealed with two sealing strips 12 and a door opening sealing strip 11. The two sealing strips 12 are the first waterproof wall to prevent water from flowing into the door. The two sealing strips 12 should not only consider the sealing function, but also reflect the water guide and drainage structure. The two sealing strips 12 are bubble tubes 4, which are assembled on the door. After the door is closed, the two sealing strips 12 are compressed to form a water guide groove 14. The water guide groove 14 is a schematic diagram of the planned water flow path 15. Water flows along the top cover into the water guide groove 14 of the two sealing strips 12 above the door, flows from the back to the front along the water guide groove 14 to the bottom of the door, and is discharged from the bottom of the door to the outside of the cab. A small amount of water is discharged from the bottom of the door to the outside of the cab. The water penetrates into the second sealing strip 12 through the vent hole, and two drainage holes are opened under the second sealing strip 12 to drain the penetrated water; the door opening sealing strip 11 is an important seal to prevent the risk of water leakage caused by improper assembly or damage of the second sealing strip 12, and to prevent water from flowing into the cab from the vehicle door. The door opening sealing strip 12 is composed of a bubble tube and a tentacle. When the vehicle door is closed, the door opening sealing strip 11 is compressed. After the door opening sealing strip 11 is deformed, it not only seals the gap between the vehicle door and the side panel 13 of the white body to prevent water from flowing into the cab, but also the bubble tube and the tentacle form a water guide groove, and the water flows along the water guide groove from back to front and is discharged from the bottom of the vehicle door to the outside of the cab.
[0033] like Figure 8 As shown, the door inner panel 10 is a part for guiding water flow. The door inner panel 10 is designed to have a concave upper portion and a convex lower portion. 2 to 3 drainage holes are designed at the bottom of the inner panel, one at each of the front and rear lower corners of the door and one in the middle. This structure allows water flowing into the door from the top of the door to drop into the door cavity and be discharged from the drainage holes at the bottom of the door inner panel 10. The mounting surface of the two sealing strips 12 above the door window frame is designed to have a low front and high rear trend, which is conducive to diverting the water accumulated at the two sealing strips 12. The mounting hole of the door inner panel accessory is designed to have a flange depth of 3 to 5 mm, that is, the door inner panel flange hole 16, which plays a diversion role.
[0034] like Figure 9-12As shown, during the driving process of the vehicle, due to the bumps and vibrations of the road, the water drops on the lower edge of the window glass 3 will drip to any position inside the door. In order to prevent water from flowing into the cab from the door, the door interior is sealed and guided by a lifter mounting plate 17 and a waterproof membrane 18. The lifter mounting plate 17 is screwed to the door inner panel 10. The lower side of the lifter mounting plate 17 is embedded in the inner side of the door inner panel 10 and is lower than the boundary of the door inner panel 10. The waterproof membrane 18 is assembled on the door inner panel 10 and the lifter mounting plate 17. To prevent water from flowing into the cab from the vehicle door through the waterproof membrane 18, the waterproof membrane 18 is fixed to the vehicle door inner panel 10 with butyl rubber on the top and on the left and right sides, and notches are designed on the front and rear sides below the waterproof membrane 18. The waterproof membrane 18 in the middle of the notch is embedded into the inner side of the vehicle door inner panel 10 and is lower than the boundary of the vehicle door inner panel 10. This structural arrangement enables the lifter mounting plate 17 and the waterproof membrane 18 to have a diversion function, that is, water flows along the mounting plate waterproof membrane to the vehicle door cavity and then is drained from the drainage hole below the vehicle door inner panel 10.
[0035] The present utility model is not limited to the above-mentioned implementation modes, and anyone should be aware of the structural changes made under the inspiration of the present utility model. Any technical solutions that are the same or similar to the present utility model fall within the protection scope of the present utility model.
