DETAILED DESCRIPTION

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1 A sealing and waterproof structure of a side panel of a hydrogen energy vehicle of the present invention comprises a top side beam 1, an exterior panel 2 and a top panel 3. The top side beam 1 and the exterior panel 2 are both two in number. The two top side beams 1 are arranged on both sides of the top of the vehicle. The two exterior panels 2 are respectively arranged on the outsides of the two top side beams 1 and are respectively fixed on the two top side beams 1. The top panel 3 is arranged on the top of the vehicle. The edge of the top panel 3 is supported on the two top side beams 1. The top panel can be a whole glass panel, metal panel or plastic panel, or it can be formed by splicing segmented glass panels, metal panels or plastic panels.

[0018] Please refer to Figure 2 and Figure 3 The sealing and waterproof structure of the side panel is a symmetrical structure. The sealing and waterproof structure of the side panel is described below by taking the sealing and waterproof structure of one side panel as an example. The top side beam 1 is an aluminum alloy one-piece extruded profile with a closed cross section. Specifically, the top side beam 1 includes an outer tube body 11 that is hollow and has a closed geometric cross section and an inner tube body 12 with a hollow structure disposed in the outer tube body. A plurality of reinforcing ribs 13 are disposed between the outer tube body and the inner tube body. The two sides of the reinforcing ribs are supported on the inner surface of the outer tube body 11 and the outer surface of the inner tube body 12, respectively, so as to connect the outer tube body 11 and the inner tube body 12 into a whole. The top side beam 1 adopts a closed cross section, has a plurality of cavities inside, and is provided with a reinforcing rib structure, which can reduce the weight of the top side beam 1 while improving the strength of the top side beam 1.

[0019] The upper surface of the top of the top side beam 1 is a connecting surface 14, and an upwardly protruding baffle 15 is provided on the connecting surface 14, and the baffle 15 is located at the outer edge of the connecting surface 14 of the top side beam 1, and the baffle 15 and the connecting surface 14 form a structure with an L-shaped cross-section, and the side edges of the top plate 3 are supported on the connecting surface 14 of the top side beam 1, and the baffle 15 is located on the outer side of the top plate 3, and a first structural adhesive 4 is provided between the lower surface of the top plate 3 and the connecting surface 14 of the top side beam 1, and the first structural adhesive 4 is used to connect the top plate 3 to the connecting surface 14 of the top side beam 1, and at the same time close the gap between the top plate 3 and the connecting surface 14 of the top side beam 1 to prevent water in the drainage channel 5 from flowing into the vehicle.

[0020] A connecting plate 21 is provided on the inner side of the top of the exterior panel 2, and the cross-section of the connecting plate 21 is also L-shaped. The connecting plate 21 is arranged on the inner side of the baffle 15. A vertically arranged sponge strip 42 is provided between the baffle 15 and the connecting plate 21. The sponge strip 42 is bonded to the connecting plate 21 of the exterior panel 2. The sponge strip 42 cooperates with the baffle 15 of the top edge beam 1 so that the sponge strip 42 is in a compressed state during the working process. The sponge strip 42 is used to close the gap between the baffle 15 and the connecting plate 21, thereby preventing water in the drainage channel 5 from flowing into the exterior panel 1. At the same time, the sponge strip 42 can also buffer the vibration impact between the baffle 15 and the connecting plate 21. A second structural adhesive 41 is provided between the connecting plate 21 and the connecting surface 14. Preferably, the second structural adhesive 41 is a 3M adhesive strip. The second structural adhesive 41 is used to connect the connecting plate 21 to the connecting surface 14 and close the gap between the connecting plate 21 and the connecting surface 14.

[0021] The edge of the top plate 3 is covered with a sealing strip 31, and the outer edge of the sealing strip 31 is connected to a water retaining protrusion 32. The sealing strip 31 is preferably made of rubber. The sealing strip 31 is used to fill the gap between the top plate 3 and the connecting plate 21 through the water retaining protrusion 32 to reduce the amount of water accumulated on the top of the car flowing into the drainage channel 5, thereby preventing a large amount of water accumulated in the drainage channel 5 from spreading into the car. At the same time, the sealing strip 31 can absorb the assembly cumulative tolerance between the top plate 3 and the exterior panel 2, ensuring the aesthetics of the joints of the top parts of the car; The connecting plate 14, the connecting surface 14 of the top side beam and the first structural adhesive 4 together form a drainage channel 5, which extends along the top side beam 1, that is, the middle of the drainage channel 5 is high and the front and rear ends are low. The drainage channel 5 can guide the water flowing into the drainage channel 5 from the top of the car to its two ends to prevent a large amount of water from accumulating in the drainage channel 5. Preferably, the connecting surface 14 on the top of the top side beam 1 is inclined, that is, the inner side of the connecting surface 14 is high and the outer side is low, so as to prevent the water in the drainage channel 5 from excessively flushing the first structural adhesive 4 and flowing into the car.

[0022] The sealing and waterproof structure of the side panel of a hydrogen energy vehicle of the present invention has the following beneficial effects: (1) The top side beam 1 of the sealing and waterproof structure adopts an aluminum alloy one-piece extruded profile with a closed cross-section, which can effectively reduce the number of parts and greatly simplify the welding process. The profile itself has a good sealing effect, which greatly reduces the cost investment of the mold clamp inspection fixture; the hollow aluminum alloy top side beam 1 with a reinforcing rib structure can greatly reduce the weight of the vehicle body and effectively improve the rigidity of the top side beam. (2) The top edge beam 1, the connecting plate 21 and the first structural adhesive 4 of the sealing and waterproof structure together form a drainage channel 5, and a sealing strip 3 is set at the edge of the top plate 3. The sealing strip 3 can fill the gap between the top plate 3 and the connecting plate 21, thereby reducing the amount of water flowing into the drainage channel 5 from the top of the car, and the drainage channel 5 can timely guide the water flowing into it, thereby preventing a large amount of water from accumulating in the drainage channel 5 and then penetrating into the interior of the car; at the same time, a sponge strip 42 is set between the baffle 15 and the connecting plate 21, which can prevent the water in the drainage channel 5 from flowing into the exterior panel 1 and can buffer the vibration impact between the baffle 15 and the connecting plate 21. (3) The sealing strip 31 between the top plate 3 and the connecting plate 21 can absorb the assembly cumulative tolerance between the top plate 3 and the exterior panel 2, ensuring the aesthetics of the joints of the top parts of the car.
