Description

Technical Field

[0001] This invention relates to the field of automotive sealing technology, and more particularly to a sealing structure for disordered opening and closing of double doors and a vehicle thereof. Background Technology

[0002] With the transformation and development of the automotive industry and the increasing demands for car configuration, space, and quality, higher requirements have been placed on automotive design and development. Currently, most mainstream cars adopt a four-door layout for passenger doors, and the vast majority use a structure design with two hinges per door. The front door hinges are generally located at the front of the door, while the rear door hinges are located on the B-pillar. To adapt to different user needs and usage scenarios, some models adopt a pillarless body design. There are generally two considerations for a pillarless body design: one is that the wheelbase is relatively short, resulting in insufficient space for second-row passengers to get in and out, necessitating the elimination of the B-pillar, with the traditional B-pillar structure moved to the rear door; the other is that some luxury models, although with a larger wheelbase, also use a pillarless body design to enhance the car's luxury attributes and fully expand the entry and exit space.

[0003] Currently, pillarless suicide door designs on the market primarily employ two hinge arrangements: First, traditional rotating hinges are used for both front and rear doors. Since the front door's side overlaps the rear door's side, the doors open sequentially. For example, to open the rear door, the front door must be opened first; conversely, to close the front door, the rear door must be closed first. This door opening and closing logic results in time-consuming and laborious entry and exit for passengers, leading to poor ergonomics. Second, while doors can open in a non-sequential manner, the hinges often employ multi-link hinges (rear swing doors), dual-axis hinges (rear rotating doors), or sliding door hinges (rear sliding doors), resulting in complex hinges and related mechanisms, significant weight, and space consumption. Both of these approaches present various disadvantages, causing problems for vehicle design and user experience. A further thorny issue for pillarless suicide door structures is the sealing and waterproofing between the two doors, especially when choosing a sealing structure for non-sequential door opening, which urgently needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to provide a sealing structure and vehicle for disordered opening and closing of double doors, solving the problems of disordered opening and closing and sealing of existing double doors without B-pillars.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A sealing structure for a double-leaf door with disordered opening and closing includes a front sealing bubble tube and a rear sealing bubble tube fixedly installed on opposite sides within the gap between the inner panels of the front and rear doors. A front magnetic adsorption strip and a rear magnetic adsorption strip are respectively installed on the opposite sidewalls of the front and rear sealing bubble tubes. When the front and rear doors are closed disorderedly, the front and rear magnetic adsorption strips attract each other, causing the front and rear sealing bubble tubes to come into close contact.

[0007] Preferably, in conjunction with the above scheme, the front door inner panel and the rear door inner panel are respectively fixedly provided with front door B-pillar trim panels and rear door front door B-pillar trim panels on their opposite sidewalls. The front door inner panel and the rear door inner panel are respectively bent to provide front door edging and rear door edging at their ends facing outwards. The front door edging and the rear door edging are symmetrically arranged. The front sealing bubble tube is disposed between the front door B-pillar trim panel and the front door edging, and the rear sealing bubble tube is disposed between the rear door front door B-pillar trim panel and the rear door edging.

[0008] Preferably, in conjunction with the above scheme, the front sealing bubble tube and the rear sealing bubble tube are fixedly connected to the front door inner panel and the rear door inner panel respectively by snap-fit ​​or adhesive.

[0009] Preferably, in conjunction with the above scheme, the two inner sidewalls of the front sealing bubble tube and the rear sealing bubble tube cavity are respectively connected to a front support rib and a rear support rib.

[0010] Preferably, in combination with the above scheme, both the front support rib and the rear support rib are Z-shaped structures.

[0011] Preferably, in conjunction with the above scheme, the outer ends of the front sealing tube and the rear sealing tube on opposite sides extend outwards to form a front sealing tongue and a rear sealing tongue, respectively; when the car door is closed, the front sealing tongue and the rear sealing tongue are in close contact.

[0012] Preferably, in conjunction with the above scheme, the hinge structure connecting the front door inner panel, the rear door inner panel and the vehicle body is the same.

[0013] Preferably, in conjunction with the above scheme, the front door inner panel and the rear door inner panel are respectively fixedly connected to the side facing the inside of the vehicle with a front door inner guard plate and a rear door inner guard plate.

[0014] Preferably, in conjunction with the above scheme, the front door inner panel and the rear door inner panel are respectively fixedly connected to the front door outer panel and the rear door outer panel on the side facing outwards from the vehicle.

[0015] The present invention also provides a vehicle, wherein the vehicle is provided with the above-mentioned double-door disordered opening and closing sealing structure and the vehicle.

[0016] The beneficial effects of the present invention are as follows: The present invention achieves a better sealing effect by setting a specially designed sealing bubble tube on the inner panels of the front and rear doors. The sealing bubble tube has a unique reverse deformation function to play a sealing role, which not only realizes the disordered opening and closing of the B-pillarless split doors, but also ensures good door sealing performance.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] Figure 1 This is a cross-sectional view of the front and rear doors with the doors closed.

[0019] Figure 2 This is a cross-sectional view of the front and rear doors with the doors open.

[0020] Figure 3 This is an enlarged cross-sectional view of a sealing structure for a double-door disordered switch according to the present invention. Detailed Implementation

[0021] like Figures 1 to 3 The diagram illustrates a disordered opening and closing sealing structure for a double-leaf door. A front sealing bubble tube 3 and a rear sealing bubble tube 4 are fixedly installed on opposite sides within the gap between the front inner panel 1 and the rear inner panel 2. A front magnetic adsorption strip 5 and a rear magnetic adsorption strip 6 are respectively installed on the opposite sidewalls of the front sealing bubble tube 3 and the rear sealing bubble tube 4. When the front inner panel 1 and the rear inner panel 2 are closed disorderedly, the front magnetic adsorption strip 5 and the rear magnetic adsorption strip 6 attract each other, bringing the front sealing bubble tube 3 and the rear sealing bubble tube 4 into close contact. The magnetic poles of the front magnetic adsorption strip 5 and the rear magnetic adsorption strip 6 are opposite to achieve mutual attraction.

[0022] To facilitate the assembly and fixation of the sealing bubble tube, the front door inner panel 1 and the rear door inner panel 2 are respectively fixedly provided with front door B-pillar trim panel 7 and rear door front door B-pillar trim panel 8 on their opposite side walls. The front door inner panel 1 and the rear door inner panel 2 are respectively bent to form front door edging 11 and rear door edging 21 at their ends facing outwards. The front door edging 11 and the rear door edging 21 are symmetrically arranged. The front sealing bubble tube 3 is located between the front door B-pillar trim panel 7 and the front door edging 11, and the rear sealing bubble tube 4 is located between the rear door front door B-pillar trim panel 8 and the rear door edging 21.

[0023] To better secure the sealing bubble tubes, the front sealing bubble tube 3 and the rear sealing bubble tube 4 are fixedly connected to the front door inner panel 1 and the rear door inner panel 2 respectively by snap-fit ​​or adhesive. If the vehicle requires floating, adhesive should be used to fix the sealing bubble tubes; in ordinary scenarios where floating is not required, snap-fit ​​fixing can also be used.

[0024] To better support and connect the components, front support ribs 31 and rear support ribs 41 are respectively connected to the two inner side walls of the front sealing bubble tube 3 and the rear sealing bubble tube 4. After prolonged use, the sealing bubble tubes may age and deform. The front support ribs 31 and rear support ribs 41 provide support to the two side walls of the sealing bubble tubes, thus extending their service life.

[0025] In order to better connect the front support rib 31 and the rear support rib 41 to the two inner side walls of the front sealing bubble tube 3 and the rear sealing bubble tube 4 respectively, and to achieve a better elastic support effect, the front support rib 31 and the rear support rib 41 are both of the Z-shaped structure.

[0026] In this embodiment, the outer ends of the front sealing tube 3 and the rear sealing tube 4 on opposite sides extend outwards to form a front sealing tongue 32 and a rear sealing tongue 42, respectively. When the car door is closed, the front sealing tongue 32 and the rear sealing tongue 42 are in close contact. When used in scenarios with certain waterproofing requirements, the front sealing tongue 32 and the rear sealing tongue 42 are designed to separate the fluid when water (liquid) attempts to enter the car from the outside.

[0027] To simplify the door hinge structure and reduce production costs, the hinge structures of the front door inner panel 1 and rear door inner panel 2 are identical to those connecting to the vehicle body. The most traditional and simple rotating double-hinge arrangement can be used in the design, which is lightweight, low-cost, and widely available.

[0028] For the sake of the aesthetics and structural design of the car doors, the front door inner panel 1 and the rear door inner panel 2 are respectively fixedly connected to the side facing the inside of the vehicle with a front door inner guard plate 9 and a rear door inner guard plate 10.

[0029] For the sake of the aesthetics and structural design of the car doors, the front door inner panel 1 and the rear door inner panel 2 are respectively fixedly connected to the front door outer panel 20 and the rear door outer panel 30 on the side facing outwards. The front door outer panel 20 and the rear door outer panel 30 are respectively fixedly connected to the front door edging 11 and the rear door edging 21.

[0030] This invention also provides a vehicle equipped with the aforementioned unordered opening and closing sealing structure for the double-door doors. The vehicle's door structure includes a front door inner panel 1, a rear door inner panel 2, a front sealing bubble tube 3, a rear sealing bubble tube 4, a front magnetic adsorption strip 5, a rear magnetic adsorption strip 6, a front door B-pillar trim panel 7, a rear door front door B-pillar trim panel 8, a front door inner guard panel 9, a rear door inner guard panel 10, a front door outer panel 20, and a rear door outer panel 30. The vehicle's front and rear doors adopt a double-opening layout. The front door hinges are conventional rotating hinged doors located at the front of the front door, while the rear door hinges are located at the rear of the rear door, the opposite of the front door hinges. Both the front and rear doors of this vehicle can be opened independently without being restricted by the closed / open state of the other door; that is, the front and rear doors can be opened and closed unordered. The key to achieving unordered door opening lies in the sealing structure between the front and rear doors, determined by the function and special structure of the front sealing bubble tube 3 and the rear sealing bubble tube 4. In practical applications, this type of sealing bubble tube can be used on one side of the car door (or body), while the other side can directly use a sheet metal (steel, iron, or magnetically adherable alloy) sealing structure. The hinge of this invention can be designed using the most traditional and simple rotating double hinge arrangement method, which is lightweight, low-cost, and has a wide range of selection resources.

[0031] The principle of this invention:

[0032] When the car door is opened, due to the elastic support of the front support rib 31 and the rear support rib 41, the front sealing tube 3 and the rear sealing tube 4 of the car door are in a retracted state in their free state, and all sealing tubes do not exceed the front door edge 11 and the rear door edge 21. During the movement of the car door around the hinge axis, there is no relative movement interference between the front and rear doors and their accessories. This solves the problem of free opening and closing of pillarless split doors, eliminating the need to open the front door first and then the rear door as in existing models. Figure 2 As shown in the figure, the dashed line represents the structure of the sealed bubble tube in its free state.

[0033] When the two doors are closed, the front sealing bubble tube 3 and the rear sealing bubble tube 4 approach each other, and their opposite side walls actively and spontaneously deform in the direction of increasing bubble tube size. This causes the sealing surfaces of the front sealing bubble tube 3 and the rear sealing bubble tube 4 to actively and tightly contact each other, so that the sealing structure between the two doors can play its role and the sealing, waterproofing and dustproofing functions can be effective.

[0034] As the car door prepares to open from its closed position, it rotates around its hinge axis, causing the sealing bulbs to shift. The two sealing surfaces of the two sets of sealing bulbs slide relative to each other until they detach. At this point, the sealing bulbs lose their magnetic attraction, and under the interaction of the bulbs' own contraction force and the magnet's interaction with the fixed sheet metal (steel, iron, or a magnetically attractive alloy), the sealing bulbs return to their free state. The sealing bulbs then retract to the inside of the door sill, ensuring no motion interference between moving and stationary objects.

[0035] Unlike traditional sealing structures that use the compression and deformation of bubble tubes to achieve ballast for sealing, the sealing structure in this embodiment involves the sealing bubble tubes being magnetically attracted and deformed, causing the previously non-contacting sealing bubble tubes to come into contact and generate a certain interaction force between them, resulting in tight contact between the two sealing bubble tubes. At this point, the two sealing bubble tubes can withstand the pressure difference between the inside and outside of the vehicle body within a certain range without separating, thus blocking the flow of air, liquid, and dust between the inside and outside of the vehicle body and achieving a sealing effect.

[0036] The sealing structure used in this invention is not limited to front and rear split doors; it can also be a top-and-bottom door or a hinged door. It can be applied to amphibious vehicles and vehicles with wading or floating applications, as well as to cargo boxes of trucks and enclosed vans that use split doors. This structure is preferentially used in vehicles, but can also be used in refrigerators and other applications requiring split doors.
