Description

Technical Field

[0001] The present invention relates to the technical field of vehicle doors, and particularly to gull-wing doors, vehicle bodies, and vehicles. Background Art

[0002] A gull-wing door is a special door design, whose main feature is that the hinge is located on the roof, and the door rotates upward when opened. For conventional doors, in a narrow parking space or on a street or other spaces, when the door is opened, a certain amount of space needs to be expanded to the side, and it is easy to be difficult to fully open due to insufficient space, and may even hit an obstacle beside. While the gull-wing door opens upward, hardly occupies the space on the side of the vehicle, and can be normally opened even in a very narrow space, facilitating passengers to get in and out of the vehicle.

[0003] However, the strength of the door body in the prior art is often low, and it is difficult to take into account sufficient structural strength while ensuring light weight. Especially when the vehicle has a side collision or rollover, the door body may be affected by insufficient support and affect the overall safety, thus limiting the application range of the gull-wing door, and it is difficult to popularize the gull-wing door in ordinary passenger cars and other vehicle models. Summary of the Invention

[0004] The purpose of the present invention is to provide a gull-wing door, a vehicle body, and a vehicle to overcome the technical problem of the small application range of the gull-wing door.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] According to the first aspect of the present application, the present application provides a gull-wing door for opening or closing a passenger compartment. The gull-wing door includes a door body, a frame structure, and a reinforcing member. The frame structure is located on one side of the door body, the frame structure is connected to the door body and encloses a frame area, and the reinforcing member is connected to the door body for enhancing the structural strength of the door body.

[0007] According to the above technical means, the frame structure is arranged along the edge of the door body. The frame structure and the door body together form an integral gull-wing door. The reinforcing member is connected to the door body, further enhancing the strength of the door body. The reinforcing member can act as a hidden B-pillar due to the setting of the gull-wing door, and jointly construct a rigid support system with the frame structure, effectively improving the strength and safety of the door body. The reinforcing member acting as the B-pillar evenly disperses the external force borne by the door, avoiding deformation due to single-point stress, and can resist external extrusion like a traditional B-pillar during a collision, maintaining the shape of the passenger compartment.

[0008] Thus, the gull-wing door can meet higher safety standards, and the applicable vehicle model range can be expanded from sports cars to SUVs, sedans, and even commercial vehicles.

[0009] In one possible embodiment, the door body includes a bottom plate, a top plate and a closing portion that are relatively arranged, the frame structure is arranged on the side of the top plate away from the top plate and is connected to the top plate; the closing portion is connected between the bottom plate and the top plate, and at least part of the reinforcement is arranged between the bottom plate and the top plate and connected to the closing portion.

[0010] According to the above technical means, the closing part connects the bottom plate and the top plate to ensure the closing and integrity of the door body, and the reinforcement is at least partially arranged between the bottom plate and the top plate and connected to the closing part. It can not only strengthen the strength of the key parts inside the door body in a targeted manner, but also act as an invisible "B-pillar" to provide longitudinal support for the door body and enhance its torsional and compressive resistance.

[0011] In one possible embodiment, the frame structure includes a top and a first side and a second side connected to both ends of the top, the end of the first side facing away from the top is connected to the top plate, and the end of the second side facing away from the top is connected to the top plate; the reinforcement includes a first part and a second part connected to each other, the first part is arranged between the bottom plate and the top plate and connected to the closed part, and the second part is connected between the first part and the top.

[0012] According to the above technical means, the window area formed by the top, the first side and the second side of the frame structure, and the connection between the first side and the second side and the top plate make the vehicle door more evenly stressed during the opening and closing process, reduce the risk of deformation, and at the same time enhance the ability of the vehicle door to resist external collision impacts. The first part of the reinforcement is arranged between the bottom plate and the top plate and is connected to the closing part, thereby strengthening the strength of the core area inside the door body and preventing dents or distortion due to stress.

[0013] In a possible embodiment, the reinforcement is arranged in a direction from the top to the bottom plate.

[0014] Using these technical measures, the reinforcements effectively and vertically transmit the impact forces exerted on the top, the weight of the door, and the torque generated during opening to the floor, preventing stress concentration on the roof or the center of the door and effectively improving the overall structure's compressive and torsional resistance. The vertically distributed reinforcements work in conjunction with the frame structure to form a stable vertical support system, enhancing the door's ability to withstand side impacts.

[0015] In a possible embodiment, the reinforcement is formed by hot air expansion.

[0016] According to the above technical means, the hot air expansion process can match the shape of the reinforcement to the internal structure of the gull-wing door, so that it fits tightly to the bottom plate, top plate and closing part of the door body. At the same time, the reinforcement formed by hot air expansion has higher impact resistance and fatigue resistance while being lightweight.

[0017] In a possible embodiment, the gull-wing door further includes a decorative component connected to at least one of the door body and the frame structure.

[0018] According to the above technical means, the decorative member can decorate the connection gap between the door body and the frame structure, and can also play an auxiliary flow guiding role. In addition, the installation of the decorative member can also buffer the impact of external forces on the connection points between the door body and the frame structure to a certain extent, improving the stability and reliability of the connection structure, so that the gull-wing door can better adapt to various usage scenarios.

[0019] In a possible implementation manner, the gull-wing door further includes a sealing member, the sealing member is arranged between the gull-wing door and the vehicle body, and the sealing member is connected to at least one of the door body and the frame structure.

[0020] According to the above technical means, the sealing member can effectively fill the gap between the gull-wing door and the vehicle body, prevent rainwater, dust, sundries, etc. from entering the vehicle interior, keep the interior of the compartment clean and dry, and at the same time avoid affecting the normal opening and closing and service life of the gull-wing door due to the entry of sundries. At the same time, the sealing member can also block external noise from entering the vehicle interior.

[0021] In a possible implementation manner, at least part of the sealing member is arranged around the door body along the circumferential side of the door body.

[0022] According to the above technical means, arranging at least part of the sealing member around the door body along the circumferential side of the door body blocks external sundries such as rainwater, dust, and sediment from entering the vehicle interior, and can also prevent foreign objects from entering and affecting the normal operation of the opening and closing mechanism of the gull-wing door.

[0023] In a possible implementation manner, the door body further includes a first anti-collision beam and a second anti-collision beam, and the first anti-collision beam and the second anti-collision beam are located inside the door body and are arranged crosswise.

[0024] According to the above technical means, the crosswise arranged first anti-collision beam and second anti-collision beam can disperse the impact forces from different directions, avoid stress concentration in a single area, and reduce the risk of local deformation.

[0025] In a second aspect of the present application, there is provided a vehicle body, which includes a vehicle body main body and the gull-wing door mentioned in any one of the above implementation manners. The vehicle body main body encloses a passenger compartment with an import and export, the gull-wing door is connected to the vehicle body main body, and the gull-wing door is used to open or close the import and export.

[0026] According to the above technical means, when the gull-wing door is opened, there is no lateral obstacle, and with the wide design of the import and export of the passenger compartment, it is convenient for passengers to get on and off the vehicle or load large items.

[0027] In a possible implementation manner, a fitting is provided at the bottom of the surface of the door body facing the vehicle body main body. The vehicle body further includes a locking member, the locking member is arranged on one side of the vehicle body main body facing the gull-wing door and is connected to the peripheral wall of the import and export, and the locking member is used to lock or release the fitting.

[0028] According to the above technical means, when the gull-wing door is closed, the bottom fitting cooperates with the locking member to achieve the closing of the gull-wing door, avoiding the opening of the door due to bumps, collisions or accidents. At the same time, the docking of the bottom fitting and the locking member can also provide an additional support point for the gull-wing door.

[0029] In a possible implementation manner, the door body further includes a first anti-collision beam and a second anti-collision beam, which are located inside the door body and cross each other; the vehicle body includes a fastening member, which is arranged on one side of the vehicle body main body facing the gull-wing door and is connected to the peripheral wall of the inlet and outlet. When the gull-wing door closes the inlet and outlet, at least one of the first anti-collision beam and the second anti-collision beam penetrates the door body and is fastened to the fastening member.

[0030] According to the above technical means, the fastening of at least one of the first anti-collision beam and the second anti-collision beam through the door body and the fastening member enhances the overall rigidity of the vehicle after the gull-wing door is closed.

[0031] The third aspect of the present application provides a vehicle, which includes the vehicle body mentioned in any one of the above implementation manners.

[0032] According to the above technical means, the vehicle provided by the present application provides a larger space for passengers to enter and exit the vehicle.

[0033] In a possible implementation manner, the vehicle further includes a driving device, which is connected between the vehicle body main body and the gull-wing door.

Detailed Embodiments

[0047] Next, the technical solutions in some embodiments of the present disclosure will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0048] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular form "comprises" and the present participle form "comprising", are interpreted in an open, inclusive sense, i.e., "including, but not limited to". In the description of the specification, the terms "some embodiments", "example", or "some examples", etc., are intended to indicate that the specific features, structures, materials, or characteristics related to the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials, or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0049] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "a plurality" is two or more.

[0050] In the description of the embodiments of the present application, unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, or an indirect connection through an intermediate medium, or the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0051] In some embodiments, referring to Figure 1 , the present application provides a vehicle, which includes a body, and the body includes a body main body and gull-wing doors connected to the body. Among them, the body main body refers to the connecting beam that encloses the cabin space of the vehicle. The body main body encloses a cabin with an entrance and exit, and the entrance and exit is the space for the driver and passengers to get on and off the vehicle. The gull-wing doors are connected to the body main body, and the gull-wing doors are used to open or close the entrance and exit.

[0052] On this basis, after the gull-wing doors are opened, the entire gull-wing doors can be lifted upward without occupying the side space. In a narrow parking environment, the driver and passengers can still easily get in and out. And when the gull-wing doors are closed, the gull-wing doors can fit tightly with the body, forming a smooth body line to reduce the wind resistance generated during the driving of the vehicle.

[0053] Taking a four-seater vehicle as an example, in this application, along the width direction of the vehicle, the body of the vehicle is only provided with one entrance and exit on one side, and a gull-wing door is used to open or close one entrance and exit. Both the front and rear passengers can conveniently enter and exit the vehicle through this single-side entrance and exit, realizing the same side door to take into account the passage of the front and rear cabins.

[0054] It should be noted that the connection method between the vehicle body and the gull-wing doors in this application is not limited to the traditional rotational connection method, and a variety of connection structures can be adopted according to actual needs. Taking a four-seater vehicle as an example, the gull-wing doors described in this application specifically refer to gull-wing doors that integrate the functions of the front and rear doors to achieve integrated and synchronous opening and closing.

[0055] In addition, the door body 100 in the present application is not an ordinary vehicle door structure, and the door body 100 refers to a door body 100 with an integrated anti-collision beam.

[0056] In some embodiments, the door body 100 further includes a first anti-collision beam and a second anti-collision beam, which are located inside the door body 100 and are cross-arranged.

[0057] The door body 100 includes an inner door panel and an outer door panel, both of which are sheet metal parts.

[0058] On this basis, the cross-arranged first and second anti-collision beams effectively disperse the collision energy from different angles through a multi-directional force structure, prevent stress concentration, and significantly reduce the risk of local deformation.

[0059] For example, the first anti-collision beam extends in the vehicle height direction, and the second anti-collision beam extends in the vehicle width direction. Of course, the first anti-collision beam and the second anti-collision beam can also extend in other directions, which is not limited in this application.

[0060] In another exemplary embodiment, the first impact beam and the second impact beam are made of thermoformed parts.

[0061] In another exemplary embodiment, the first anti-collision beam and the second anti-collision beam are made by rolling steel sections.

[0062] In some embodiments, see Figure 1 、 Figure 2 and combined Figure 3 The gull-wing door of the present application is used to open or close the vehicle cabin. The gull-wing door includes a door body 100, a frame structure 200, and a reinforcement member 300. The frame structure 200 is located on one side of the door body 100. The frame structure 200 is connected to the door body 100 and encloses a frame area. The frame area can enclose the window area of the vehicle door. The window area enclosed by the frame area is the total window area of the front and rear cabins. The reinforcement member 300 is connected to the door body 100 and is used to enhance the structural strength of the door body 100.

[0063] The difference between the reinforcement member 300 and the anti-collision beam is that the anti-collision beam mainly plays a role when the vehicle encounters a collision, absorbs the impact energy through its own deformation, and protects the safety of the vehicle occupants; the purpose of the reinforcement member 300 in this application is to enhance the structure of the door body 100 of the gull-wing door.

[0064] It should be noted that the door body 100 and the frame structure 200 in this application can be integrally formed or separately formed, and this application does not make any limitations in this regard.

[0065] Correspondingly, the window glass can also be a unified control for integrally formed parts, or can be separately arranged to meet the independent control requirements, and this application does not make any limitations in this regard. On this basis, the connection between the reinforcement member 300 and the door body 100 can enhance the anti-deformation ability of the door, thereby enhancing the overall strength of the vehicle.

[0066] The B-pillar, as a key structural component of the vehicle, plays a crucial role in vehicle safety and structural stability. It is the core pillar connecting the roof and the vehicle floor. During a side collision, the B-pillar needs to bear and disperse most of the impact force to prevent the door from invading the passenger compartment, which is directly related to the safety of the people in the vehicle; at the same time, the B-pillar is of great significance for maintaining the body rigidity and torsional strength. During the driving process of the vehicle, it helps the body resist the torsional deformation caused by road bumps, turning, etc., and ensures the handling stability and riding comfort.

[0067] In this application, even though the special door design of the gull-wing door is adopted, under the synergistic effect of structures such as the frame structure 200, the reinforcement member 300, and the anti-collision beam, the application range of the gull-wing door is increased. The first anti-collision beam and the second anti-collision beam arranged crosswise absorb and disperse energy efficiently during a collision, and the reinforcement member 300 can enhance the strength of the gull-wing door body, thereby enhancing the structural strength and stability of the door body 100, and greatly improving the overall reliability of the vehicle.

[0068] In addition, this application connects the frame structure 200 of the gull-wing door with the door body 100 to enclose a unified window area covering the front and rear passenger compartments, and the front and rear doors and the reinforcement member 300 acting as the B-pillar are actually an integral whole, which cooperates with the reinforcement member 300 to enhance the strength of the door body 100.

[0069] At the same time, the stable support of the reinforcement member 300 provides a reliable installation basis for various intelligent functions. The integrated frame area is integrated with the decorative panels of various intelligent functions, providing sufficient layout space for side cameras, display screens, password opening and biometric devices, etc., to achieve function integration. For example, the side camera can obtain a wider field of view through the integrated window area, while the password opening, face or fingerprint recognition device can be cleverly integrated with the B-pillar, which not only does not damage the aesthetic appearance, but also is convenient for users to operate, making the gull-wing door not only have structural safety, but also become a display window for vehicle intelligence and personalization, enhancing the overall vehicle technology sense and user experience.

[0070] In some embodiments, the door body 100 includes a bottom plate 102 and a top plate 101 and a closing portion 103 that are relatively arranged, and the frame structure 200 is arranged on the side of the top plate 101 away from the top plate 101 and is connected to the top plate 101; the closing portion 103 is connected between the bottom plate 102 and the top plate 101, and at least a portion of the reinforcement 300 is arranged between the bottom plate 102 and the top plate 101 and is connected to the closing portion 103.

[0071] On this basis, the sealing portion 103 is connected between the bottom plate 102 and the top plate 101. As the part of the door body 100 below the window, it isolates the interior of the vehicle from the outside world, providing sealing and protection. It is also connected to the reinforcement 300, transmitting force to the reinforcement 300 when subjected to external forces, thereby jointly resisting damage to the door body 100.

[0072] The reinforcement member 300 is at least partially located between the bottom plate 102 and the top plate 101 and connected to the closure portion 103. When the door body 100 is subjected to external forces, the reinforcement member 300 uses its own strength and rigidity to disperse and withstand these forces, preventing deformation or damage to the door body 100. For example, when a vehicle is involved in a collision or other external impact, the reinforcement member 300 can effectively distribute the force between the bottom plate 102, the top plate 101, and the closure portion 103, preventing excessive local forces from causing structural failure of the door body 100.

[0073] In this way, the frame structure 200 , the closing portion 103 and the reinforcement 300 cooperate with each other to form a stable overall structure, which greatly improves the strength and deformation resistance of the door body 100 .

[0074] Of course, the reinforcement 300 may also extend out of the door body 100 area and be connected to the vehicle frame structure 200 , which is not limited in this application.

[0075] In some embodiments, see Figure 1 、 Figure 2 and combined Figure 3, the frame structure 200 includes a top portion 201 and a first side portion 202 and a second side portion 203 connected to both ends of the top portion 201. One end of the first side portion 202 facing away from the top portion 201 is connected to the top plate 101, and one end of the second side portion 203 facing away from the top portion 201 is connected to the top plate 101; the reinforcing member 300 includes a connected first portion and a second portion. The first portion is disposed between the bottom plate 102 and the top plate 101 and is connected to the closed portion 103, and the second portion is connected between the first portion and the top portion 201. On this basis, the first portion of the reinforcing member 300 is disposed between the bottom plate 102 and the top plate 101 and is connected to the closed portion 103, and the second portion is connected between the first portion and the top portion 201 of the frame structure 200, which forms a continuous support structure from the bottom plate 102 to the top plate 101. Just like a B-pillar, the reinforcing member 300 can effectively transfer and disperse the forces from different parts of the door body 100, such as the impact force when closing the door, the vibration during vehicle driving, and the possible collision force, etc., between the bottom plate 102, the top plate 101 and the frame structure 200, preventing the door body 100 from being excessively deformed or damaged due to local stress and maintaining the overall structural integrity of the door body 100. Thus, through the reinforcing member 300 of the present application, a firm connection can be formed between the door body 100 and the frame structure 200, thereby ensuring reliable structural strength during the opening, closing and use of the gull-wing door. The gull-wing door can not only adapt to the sports scenarios of high-end sports cars, but also be extended to various vehicle models such as SUVs and MPVs. It can be understood that the present application broadens the applicable range of the gull-wing door in the automotive field, bringing richer product choices and innovative experiences to users. In some embodiments, please refer to Figure 1 , Figure 2 and in combination with Figure 3 , the reinforcing member 300 is arranged in the direction from the top portion 201 to the bottom plate 102.

[0076] On this basis, the reinforcing member 300 can directly bear the pressure from the top portion 201 of the gull-wing door and the vertical vibration and impact force generated during vehicle driving. And when the gull-wing door is subjected to an external force, for example, a lateral force during the opening or closing process, or an impact force from the side during a vehicle collision, the reinforcing member 300 arranged in the direction from the top portion 201 to the bottom plate 102 can provide a direct and efficient force conduction path. The external force can be quickly conducted along the reinforcing member 300 to the entire door body 100 structure and the vehicle body, so that each part of the door body 100 can be stressed in cooperation, avoiding excessive local stress and improving the overall anti-deformation ability and anti-impact performance of the gull-wing door.

[0077] Exemplarily, the reinforcing member 300 extends along the height direction of the vehicle. Of course, the reinforcing member 300 can also extend in a direction intersecting with the height direction of the vehicle, and the present application does not make a limitation in this regard.

[0078] In some embodiments, please refer toFigure 1 、 Figure 2 Combined with Figure 3 Reinforcement 300 is formed using hot air expansion. During this process, the material undergoes structural reconstruction and grain refinement under high temperature and pressure, resulting in enhanced strength and toughness. Serving as a hidden B-pillar, reinforcement 300 effectively absorbs and disperses impact forces in a side collision, just like a traditional B-pillar. While leveraging its superior mechanical properties, it minimizes deformation, providing a safe space for occupants. Furthermore, it can withstand greater impact forces than components formed using traditional manufacturing methods.

[0079] In some embodiments, see Figure 1 、 Figure 2 Combined with Figure 3 The gull-wing door also includes a decorative piece 400, which is connected to at least one of the door body 100 and the frame structure 200. This decorative piece 400 provides protection from external scratches, collisions, and other damage. Gaps or joints between the door body 100 and the frame structure 200 can affect the appearance of the door. The decorative piece 400 cleverly conceals these gaps, thereby enhancing the aesthetics of the gull-wing door.

[0080] For example, there are multiple decorative pieces 400. These include a first decorative piece 401, which is connected between the top 201 of the frame structure 200 and the vehicle body to prevent foreign objects from entering the vehicle interior through the top of the gull-wing doors. Furthermore, the complete first decorative strip can run from the front to the rear of the vehicle, extending along the contour of the gull-wing doors to form a smooth line, giving the vehicle a more integrated and coherent appearance.

[0081] As another example, the plurality of decorative parts further include a second decorative part 402, which is connected between the top 201 of the frame structure 200 and the top plate 101 of the door body 100, and the second decorative part 402 covers the outside of the second part of the reinforcement 300 to form a shielding.

[0082] In another exemplary embodiment, the plurality of decorative elements further includes a third decorative element 403, which is disposed at the bottom of the door body 100. When the door body 100 rubs against curb steps or obstacles, the third decorative element 403 directly absorbs the impact, protecting the door body 100 and reducing repair costs. Furthermore, the third decorative element can be made of an elastic material to absorb the impact of minor collisions and minimize damage to the door body 100.

[0083] In some embodiments, see Figure 1 、 Figure 2 Combined with Figure 3, the gull-wing door further includes a seal 500 disposed between the gull-wing door and the vehicle body, and the seal 500 is connected to at least one of the door body 100 and the frame structure 200.

[0084] On this basis, when the vehicle is running, the seal 500 can make the connection between the gull-wing door and the vehicle body closer, so as to reduce the leakage and disorder of the air flow at the door gap, enable the air flow to flow more smoothly over the vehicle body surface, and thus reduce the wind resistance.

[0085] The sealing structure between the traditional B-pillar and the door body 100 often forms obvious gaps and boundaries on the side of the vehicle body, affecting the smoothness of the overall shape. In the present application, the connection between the gull-wing door and the vehicle body is more concise, which not only reduces the cost and the weight of the whole vehicle, but also improves the aesthetics of the vehicle.

[0086] In some embodiments, please refer to Figure 1 、 Figure 2 and in combination with Figure 3 , at least part of the seal 500 is disposed around the door body 100 along the circumferential side of the door body 100. The seal 500 can be a vehicle lower edge seal 500 or a side wall seal 500.

[0087] On this basis, the seal 500 can seal the gap between the door body 100 and the vehicle body to prevent foreign impurities from entering the vehicle, and at the same time can also prevent the gas in the vehicle from flowing out or the gas outside the vehicle from flowing in, so as to ensure the stability of the air pressure in the vehicle and avoid the noise and discomfort caused by air flow leakage.
