[0002] As people's demands for buses continue to rise, the humanized design of buses is becoming increasingly refined. The luggage compartment of a large bus, serving as a storage space for passengers' luggage and other items, is crucial for optimizing its performance, yet its sealing and waterproofing are often overlooked.

[0003] At present, the hinge arrangement commonly used in vehicle side doors is generally a single-axis hinge. This hinge arrangement mainly connects the hinge to the water trough, which is welded or riveted to the waist beam. This structure is widely used due to its simple structure and easy maintenance. However, in this single-axis hinge arrangement, on the one hand, the water trough occupies a large longitudinal space of the opening, affecting the convenience of taking luggage. On the other hand, the water trough occupies the longitudinal space of the door side pillars. In order to ensure the rigidity of the side wall, the door side pillars and the side wall pillars need to be staggered. The door side pillars extend laterally along the side wall pillars into the vehicle interior, thereby occupying a large space inside the vehicle, which is not conducive to the installation and fixation of the heater seat.

[0068] See Figure 1 As shown in Figure 5, Figure 1 1 shows a front view of the side hatch sealing and waterproofing system provided in one embodiment of the present application. Figure 2 A schematic side view of the side hatch sealing and waterproofing system provided in one embodiment of the present application is shown. Figure 3 FIG2 shows a schematic structural diagram of a second sealing member in a side hatch sealing and waterproofing system provided in an embodiment of the present application. Figure 4 The figure shows a schematic structural diagram of the inner plate profile in the side hatch sealing and waterproofing system provided in one embodiment of the present application. Figure 5a and Figure 5b A schematic diagram of the hinge structure of a side hatch door sealing and waterproofing system provided in one embodiment of the present application is shown. The side hatch door sealing and waterproofing system provided in one embodiment of the present application includes: a side hatch door 100, a hatch door side pillar 200, a waist beam 300, a side panel pillar 400, and a side hatch door sealing and waterproofing device 500. The side hatch door 100 is hingedly connected to the hatch door side pillar 200; the waist beam 300 is mounted on top of the hatch door side pillar 200; the side panel pillar 400 is located on top of the side hatch door 100 and connected to the waist beam 300; and the side hatch door sealing and waterproofing device 500 is mounted between the inner side of the side hatch door 100 and the hatch door side pillar 200.

[0069] The side hatch sealing and waterproofing device 500 used in the side hatch sealing and waterproofing system provided in the present application does not require a water flow trough structure, occupies a small dimension in the height direction of the hatch opening, and increases the usable space of the hatch opening, which is conducive to taking luggage; at the same time, the structural arrangement of the hatch side pillars and the waist beam can avoid the hatch side pillars occupying the space inside the vehicle while ensuring the rigidity of the vehicle body.

[0070] In one embodiment of the present application, the side door 100 and the door side pillar 200 are hingedly connected via a hinge 700 .

[0071] Optionally, the two side doors 100 are hinged to a door side column 200 via a hinge 700. The two side doors 100 share one hinge 700, which can reduce the number of hinges 700, help reduce the weight of the system, and simplify the assembly process.

[0072] In one embodiment of the present application, the side hatch door sealing and waterproofing device 500 includes: an inner panel profile 510, a first sealing member 520, and a second sealing member 530. The first end of the inner panel profile 510 is hinged to the side hatch door 100 and the hatch door side pillar 200, and the second end of the inner panel profile 510 is attached to the inner surface of the door panel of the side hatch door 100; the first sealing member is arranged between the inner side of the side hatch door 100 and the hatch door side pillar 200 along a first direction (horizontal direction as shown in the figure), wherein the first direction is configured to be perpendicular to both the inner side of the side hatch door 100 and the hatch door side pillar 200; the first end of the first sealing member 520 is hinged to the hatch door side pillar 200. The sealing stop 210 of the pillar 200 is clamped, and the second end of the first seal 520 abuts against the inner side of the side door 100; the second seal is arranged between the inner panel profile 510 and the first seal 520 along a second direction (vertical direction as shown in the figure), wherein the second direction is configured to be perpendicular to the first direction; the first end of the second seal 530 abuts against the side wall of the door side pillar 200, and the second end of the second seal 530 is clamped with the inner panel profile 510.

[0073] Specifically, in this embodiment, the inner panel profile 510 is bonded to the side door 100 and rotates up and down with the side door 100. A second seal 530 is snapped onto the inner panel profile 510. One end of the second seal 530 is in compression contact with the side wall of the door side pillar 200. The second seal 530 elastically seals between the inner side of the side door 100 and the door side pillar 200. When the side door 100 rotates, water flows to the second seal 530, effectively guiding water.

[0074] The structure of the second sealing member 530 is described in detail below. Figure 3As shown, the second seal 530 includes a second seal body 531, a clamping block 532, a first support arm 533, and a compression arm 534. The second seal body 531 is arranged along the first direction (horizontally as shown in the figure); the clamping block 532 is connected to the second seal body 531 in a direction relative to the waist beam 300 (vertically upward as shown in the figure); the clamping block 532 is engaged with the inner panel profile 510, securing the second seal 530 to the inner panel profile 510. The first support arm 533 is connected to the second seal body 531 in a direction relative to the waist beam 300 (vertically upward as shown in the figure); the first support arm 533 and the clamping block 532 clamp the inner panel profile 510 at the clamping interface, thereby increasing the rigidity of the inner panel profile 510 at this location. The compression arm 534 is arranged along the first direction (the horizontal direction as shown in the figure), the first end of the compression arm 534 is connected to one end of the second sealing body 531 relative to the hatch side column 200, and the second end of the compression arm 534 abuts against the side wall of the hatch side column 200.

[0075] Regarding the compression arm 534, it should be noted that the compression arm 534 shown in the figures is an elastic ring structure. Upon contact with the sidewall of the door side pillar 200, it elastically deforms to ensure a sealed connection between the second seal 530 and the sidewall of the door side pillar 200. Preferably, the second end of the compression arm 534 is convex relative to the waist beam 300. In this case, the second seal body 531, the compression arm 534, and the first support arm 533 cooperate to form a water channel, converging and directing liquid flowing into the second seal 530. The structure of the compression arm 534 is not limited to the one shown in the figures; any structure capable of deforming to achieve a sealed connection between the second seal 530 and the sidewall of the door side pillar 200 is applicable, and no specific examples are given here.

[0076] Furthermore, the second seal 530 also includes a second support arm 535. The second support arm 535 is connected to the second seal body 531 in a direction opposite to the waist beam 300 (vertically downward as shown in the figure); the second support arm 535 contacts the second end of the inner panel profile 510. In this embodiment, the second support arm 535 and the first support arm 533 are both supported on the inner panel profile 510. The second support arm 535 and the first support arm 533 cooperate to increase the rigidity and stability of the second seal 530, preventing the second seal 530 from tilting or falling during the sealing process, and improving the reliability of the second seal 530 in sealing and water diversion.

[0077] In one embodiment of the present application, the inner panel profile 510 includes an inner panel profile body 511, an inner panel profile engagement interface 512, and an extended connection surface 513. The inner panel profile body 511 defines a hinged mounting hole 514. The inner panel profile engagement interface 512 is located at the bottom of the inner panel profile body 511 and engages with a side of the second sealing member 530 proximate to the side door 100. The extended connection surface 513 is connected to a side of the inner panel profile body 511 proximate to the inner panel profile engagement interface 512 and is attached to the inner surface of the door panel of the side door 100.

[0078] In one embodiment, the extended connection surface 513 is bonded to the inner surface of the door panel of the side door 100. The hinged mounting hole 514 on the inner panel profile, the side door 100, and the door side pillar 200 are coaxially hinged. The inner panel profile 510 rotates relative to the door side pillar 200 as the side door 100 opens and closes. Alternatively, the hinged mounting hole 514 on the inner panel profile, the side door 100, and the door side pillar 200 are coaxially hinged via the pin 720 of the hinge 700.

[0079] Furthermore, the bushing 600 is sleeved in the hinge mounting hole 514 , and the bushing 600 is located between the hinge mounting hole 514 and the pin shaft 720 of the hinge 700 .

[0080] The bushing 600 has an interference fit within the hinge mounting hole 514, preventing the pin 720 of the hinge 700 from directly pivoting and rotating with the hinge mounting hole 514, thereby preventing wear and tear on the hinge mounting hole 514 and effectively extending the service life of the accessory. The bushing 600 also has a clearance fit with the pin 720 of the hinge 700.

[0081] The bushing 600 is made of non-metallic materials, such as a nylon bushing.

[0082] The structure of the hinge 700 is described in detail below. Figure 5a 、 Figure 5b As shown, the hinge 700 includes a hinge base 710 and at least one pin 720. The hinge base 710 is mainly used for positioning and installing the hinge 700 on the door side column 200, and the pin 720 is mainly used for hinge connection between the hinge 700 and the side door 100.

[0083] In one specific embodiment, a pin 720 is connected to each side of the hinge base 710, and each pin 720 can be hinged to a side door 100. The hinge base 710 can be provided with multiple connection points, typically screwed, to quickly and conveniently secure the hinge base 710 to the door side pillar 200. In this embodiment, the hinge 700 can have an L-shaped, sheet-like structure, facilitating connection between the two ends of the hinge 700 and the side door 100 and the door side pillar 200, respectively. The structure of the hinge 700 is not specifically limited and can be adaptively adjusted based on the gap between the side door 100 and the door side pillar 200.

[0084] There is no specific limitation on the arrangement of the connection points on the hinge seat 710. You can choose to arrange four connection points in an array on the hinge seat 710 as shown in the figure, or you can choose connection points distributed in a ring shape, connection points distributed in a dispersed shape, etc., which are not listed here one by one.

[0085] In one embodiment of the present application, a vehicle is provided, including the side hatch door 100 sealing and waterproofing system described above. The hatch door side pillar 200 is connected to the vehicle body frame via rivets. One end of a second sealing member 530 in the side hatch door sealing and waterproofing device 500 is clamped onto an inner panel profile 510, while the other end of the second sealing member 530 is in compressive contact with the flat surface of a sealing stop 210 welded to the vehicle body frame, achieving a sealing and water-conducting effect. One end of a first sealing member 520 is clamped onto the sealing stop 210, while the other end of the first sealing member 520 is in compressive contact with the flat surface of the inner side of the side hatch door, achieving a primary watertight seal between the inner side of the side hatch door 100 and the hatch door side pillar 200.

[0086] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
