[0024] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0025] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] In order to achieve a seal between the door and the vehicle body, a sealing strip extending along the circumference of the door is usually provided at the outer edge of the door. When the door is closed, the sealing strip abuts against the sealing surface on the side of the vehicle body. However, in some specific scenarios, such as when the door is closed, the sealing strip is subjected to a large impact force. Over time, the sealing strip may be excessively deformed, affecting the sealing performance of the sealing strip, and may allow dust and water in the external environment to enter the vehicle, affecting the normal use of the vehicle.

[0027] Therefore, the embodiment of the present application provides a door structure and a vehicle, which, by arranging a support member inside the annular sealing strip, ensures that when the annular sealing strip is subjected to a large impact force, the annular sealing strip will not undergo a large deformation, thereby maintaining the sealing performance of the annular sealing strip and maintaining the sealing performance of the sealing assembly, so that the vehicle can be used normally.

[0028] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figures 1 to 4 , Figure 1 A schematic diagram of a partial structure of a vehicle provided in an embodiment of the present application, Figure 2 A schematic structural diagram of a local structure of a vehicle body in an embodiment of the present application. Figure 3 A schematic diagram of a partial structure of a door structure provided in an embodiment of the present application, Figure 4 for Figure 3 The cross-section along the AA direction. Figure 1 The direction shown is the direction looking outward from the inside of the vehicle body.

[0030] As shown in the figure, this embodiment provides a door structure, including a door 1, the inner side of the door 1 is used to set a structure such as an item storage slot. It is understandable that when the door 1 is in a closed state, if the sealing between the door 1 and the vehicle body 2 is poor, external dust and the like will enter the interior of the vehicle body 2.

[0031] Therefore, generally, a corresponding sealing assembly is provided at the edge of the inner side of the vehicle door 1. Specifically, the sealing assembly includes an annular sealing strip 3, and the annular sealing strip 3 presses against the sealing surface 21 on the side of the vehicle body 2 when the vehicle door is in a closed state. The sealing surface 21 on the side of the vehicle door can be a surface that is recessed inward relative to the side of the vehicle body 2, and this surface is arranged around the outer side of the door opening 22 on the vehicle body 2. When the vehicle door 1 is in a closed state, the annular sealing strip 3 is sandwiched between the outer edge of the inner side of the vehicle door 1 and the sealing surface 21. Therefore, when the vehicle door 1 is in a closed state, the annular sealing strip 3 cannot be seen on either the outer side or the inner side of the vehicle body 2.

[0032] In order to maintain the aesthetics of the vehicle, the shape of the annular sealing strip 3 should be adapted to the outer edge shape of the vehicle door 1. Here, the shape of the annular sealing strip 3 is not specifically limited.

[0033] It should be noted that the annular sealing strip 3 can be made of rubber, and the connection between the annular sealing strip 3 and the vehicle door 1 can be bonding, illustratively, can be bonding by tape. Here, the bonding method between the annular sealing strip 3 and the vehicle door 1 is not specifically limited.

[0034] For example, when the vehicle door 1 is closed, the annular sealing strip 3 is subjected to a large impact force. After encountering scenes with large impact forces for many times, and combined with the material of the annular sealing strip 3 itself, the annular sealing strip 3 may be excessively deformed, which will affect the sealing performance of the annular sealing strip 3.

[0035] Therefore, in this embodiment, when the annular sealing strip 3 is subjected to impact force, a reverse supporting force can be generated on the annular sealing strip 3, so as to avoid excessive deformation of the annular sealing strip 3 to a certain extent. Therefore, the above-mentioned sealing assembly further includes a supporting member 4, a cavity 31 is formed in the annular sealing strip 3, the supporting member 4 is accommodated in the cavity 31, and the supporting member 4 is used to generate a supporting force on the annular sealing strip 3 when the annular sealing strip 3 is subjected to external force. In this way, by arranging the supporting member 4 inside the annular sealing strip 3, and making the supporting member 4 generate a supporting force on the annular sealing strip 3 when the annular sealing strip 3 is subjected to external force, in this way, compared with the single sealing strip in the related art, the annular sealing strip 3 in this embodiment is supported by the supporting member 4, so that even when the sealing assembly is subjected to a large impact force, the excessive deformation of the sealing assembly can be avoided to a certain extent, so that the sealing performance of the sealing assembly is better.

[0036] It should be noted that the impact force exerted on the annular sealing strip 3 may be the impact force exerted when the vehicle door is closed, and the direction of the above-mentioned supporting force is based on the cross-sectional shape of the sealing assembly. The direction from the center of the annular sealing strip 3 to the outer edge of the annular sealing strip 3 along the radial direction of the cross-sectional shape of the annular sealing strip 3 is the direction of the supporting force.

[0037] In some optional embodiments, the support member 4 may also be made of a material such as rubber. In this case, if the support member 4 is to provide support for the annular sealing strip 3, gas may be filled in the support member 4. The support of the gas on the support member 4 may cause the support member 4 to deform, thereby generating a supporting force for the annular sealing strip 3.

[0038] Specifically, the above-mentioned cavity 31 can extend along the circumference of the annular sealing strip 3; the extension direction of the support member 4 is consistent with the extension direction of the cavity 31, and a gas storage cavity 41 extending along the extension direction of the support member 4 is formed inside the support member 4, and the gas storage cavity 41 is used to store gas; wherein, when the annular sealing strip 3 is subjected to external force, the gas content in the gas storage cavity 41 increases, so that the support member 4 is deformed and supported on the annular sealing strip 3. It can be understood that when the gas content in the gas storage cavity 41 increases, the support member 4 will expand outward, that is, based on the cross-sectional shape of the sealing component, the deformation direction of the support member 4 is basically consistent with the direction of the above-mentioned supporting force, and at this time, the side wall of the support member 4 will abut against the inner wall surface of the annular sealing strip 3. In this way, a certain supporting effect can be exerted on the annular sealing strip 3.

[0039] It is understandable that in different scenarios, the amount of gas stored in the gas storage chamber 41 should also be different. For example, when the vehicle door 1 is in a closed state, it is necessary to ensure the sealing performance between the outer edge position of the inner side of the vehicle door 1 and the sealing surface 21. At this time, it is necessary to ensure that the amount of gas stored in the gas storage chamber 41 is sufficient; when the vehicle door 1 is in an open state, at this time, during the use of the vehicle, the vehicle door 1 needs to be closed. When closing the vehicle door 1, it is necessary to keep the resistance to the vehicle door 1 small so that it is convenient to close the vehicle door 1. At this time, the amount of gas stored in the gas storage chamber 41 should be less. Therefore, it is necessary to set a corresponding structure to change the amount of gas in the gas storage chamber 41.

[0040] Therefore, in some optional implementations, the vehicle door structure provided in this embodiment may further include an air-inflating and air-deflating assembly 5, which is connected to the support member 4 and the annular sealing strip 3, and is in communication with the air storage chamber 41; the air-inflating and air-deflating assembly 5 is used to inflate the air storage chamber 41 when the vehicle door 1 is in a closed state, and is used to suck the gas in the air storage chamber 41 when the vehicle door 1 is in an open state. In this way, the provision of the air-inflating and air-deflating assembly 5 can not only ensure the sealing performance of the sealing assembly, but also prevent the opening of the vehicle door 1 from being affected by the excessive amount of gas in the air storage chamber 41.

[0041] In some specific embodiments, the above-mentioned inflation and deflation assembly 5 may include an air pump 51 and an air pipe 52. The air pump 51 is arranged inside the vehicle door 1. It can be understood that, generally, the vehicle door 1 is composed of two inner and outer sheet metals spliced ​​together, for example, they are connected together by threaded fasteners such as screws. At this time, the air pump 51 can be arranged between the inner and outer sheet metals.

[0042] Furthermore, one end of the air pipe 52 is connected to the air pump 51, and the other end of the air pipe 52 passes through the side wall of the cavity 31 and the side wall of the air storage cavity 41 in sequence and communicates with the air storage cavity 41. In this way, by providing the air pump 51 and the air pipe 52, when the door 1 is in a closed state, the air storage cavity 41 is inflated through the air pump 51 and the air pipe 52; when the door 1 is in an open state, the air in the air storage cavity 41 is extracted outward through the air pump 51 and the air pipe 52.

[0043] It is understandable that a control module is provided inside the vehicle, and the state of the air pump 51 can be controlled by the control module. Here, the control method of the air pump 51 is not described in detail.

[0044] Since the air pipe 52 needs to pass through the side wall of the air storage cavity 41 and the side wall of the cavity 31, the support member 4 may be provided with a first through hole 42 for the air pipe 52 to pass through, and the annular sealing strip 3 may be provided with a second through hole 33 for the air pipe 52 to pass through, and the second through hole 33 is arranged opposite to the first through hole 42; wherein the aperture of the first through hole 42 is equal to the diameter of the air pipe 52, the aperture of the second through hole 33 is larger than the diameter of the air pipe 52, and the inner wall of the second through hole 33 and the wall of the air pipe 52 are filled with adhesive 6. In this way, the air pipe 52 can pass through the side wall of the air storage cavity 41 and the side wall of the cavity 31.

[0045] The adhesive 6 may be a solid glue to ensure the airtightness of the cavity 31 and prevent the entry of dust from the outside.

[0046] In some embodiments, since the diameter of the first through hole 42 is equal to the diameter of the air pipe 52, the air pipe 52 and the support member 4 can be integrally formed when the air pipe 52 is connected to the support member 4. In this way, on the one hand, the airtightness in the air storage cavity 41 can be ensured, and on the other hand, the molding and manufacturing efficiency between the support member 4 and the air pipe 52 can be improved.

[0047] The air pipe 52 and the support member 4 can be integrally formed by injection molding. Here, the molding method between the air pipe 52 and the support member 4 is not specifically limited.

[0048] It is understandable that if the wall thickness of the air pipe 52 is relatively large, when the sealing assembly is subjected to a large impact force, the air pipe 52 will bear more force, and in order to make the impact force be concentratedly borne by the support member 4, it is necessary to limit the wall thickness of the air pipe 52 in this embodiment, specifically, the wall thickness of the air pipe 52 is between 0.7 mm and 1.2 mm. In this way, by limiting the wall thickness of the air pipe 52, it is possible to avoid the air pipe 52 from being subjected to a large impact force to a certain extent, thereby improving the service life of the air pipe 52, and further ensuring that the amount of gas in the air storage chamber 41 is relatively appropriate in various use scenarios, thereby improving the overall performance of the vehicle.

[0049] For example, the wall thickness of the air pipe 52 may be 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, etc. Here, the wall thickness of the air pipe 52 is not specifically limited.

[0050] In a specific embodiment, the wall thickness of the air tube 52 may be 1.0 mm.

[0051] It is understandable that if the external annular sealing strip 3 itself has a large mass, then when the sealing assembly is subjected to impact force, the annular sealing strip 3 will bear more impact force and is prone to excessive deformation. Therefore, excessive deformation of the annular sealing strip 3 can be avoided by reducing the mass of the annular sealing strip 3 itself.

[0052] Specifically, a groove 311 may be formed on the inner wall of the cavity 31; the groove 311 is provided on both the side of the support member 4 close to the outer edge of the door 1 and the side away from the outer edge of the door 1, and the notch of the groove 311 is provided toward the support member 4. In this way, the mass of the annular sealing strip 3 itself can be reduced, so that when the sealing assembly is subjected to impact force, the support member 4 can bear more, and the impact force on the annular sealing strip 3 itself is smaller. In this way, the excessive deformation of the annular sealing strip 3 can be avoided to a certain extent, thereby improving the sealing performance of the sealing assembly.

[0053] In order to further reduce the mass of the annular sealing strip 3, in some embodiments, a plurality of grooves 311 are provided at intervals on the side of the support member 4 close to the outer edge of the vehicle door 1 and the side away from the outer edge of the vehicle door 1; the grooves 311 extend in a closed loop along the circumference of the annular sealing strip 3. In this way, the mass of the annular sealing strip 3 can be further reduced, so that the internal support member 4 can withstand more impact force, ensuring the sealing performance of the sealing assembly.

[0054] This embodiment further provides a vehicle, comprising a vehicle body and the door structure in the above embodiment. The structure of the door structure has been described in detail in the above embodiment, and will not be described in detail here.

[0055] It should be noted that the vehicle provided in this embodiment should also include other mechanisms or components such as wheel components, which will not be introduced one by one here.

[0056] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
