Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a door structure. This application also relates to a door using this door structure, and a vehicle using this door. Background Technology

[0002] As a key structure of automobiles, car doors not only provide convenience for passengers to get in and out of the vehicle, but also have a significant impact on the overall structural safety, sealing, and noise reduction of the vehicle. Frameless doors are a type of car door structure that breaks with traditional design. Their core feature is the elimination of the metal window frame that fixes the glass, retaining only the connection structure between the glass body and the interior / exterior trim of the door.

[0003] The existing frameless car doors have triangular panels located mainly on both sides of the front and rear bumpers, below the doors, or in the fender area. They are mostly triangular or trapezoidal in shape and are generally matched with the glass grooves to seamlessly connect with the door and other structures, forming the streamlined appearance of the car body.

[0004] The existing frameless doors have the following problems: the glass groove is prone to deformation, the sealing performance is poor, and there is a risk of noise and water leakage when rain falls. Utility Model Content

[0005] In view of this, this application aims to propose a door structure to reduce the risk of water leakage in the glass groove area.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0007] A door structure for use in a frameless door includes a door sheet metal assembly and a glass guide rail connected to one side of the door sheet metal assembly.

[0008] The door sheet metal assembly has a first insertion part that inserts into the glass groove of the frameless door, and the glass guide rail has a second insertion part that inserts into the glass groove, with a notch between the first insertion part and the second insertion part;

[0009] A reinforcing part is connected between the door sheet metal assembly and the glass guide rail, and the reinforcing part is positioned at the notch.

[0010] Furthermore, the door sheet metal assembly includes an inner door panel and an inner door panel reinforcement plate connected to the outer side of the inner door panel;

[0011] Both the glass guide rail and the reinforcing part are connected to the outside of the inner panel reinforcing plate of the door.

[0012] Furthermore, the reinforcing part includes a reinforcing plate and a mounting plate connected to one side of the reinforcing plate;

[0013] The lower part of the reinforcing plate is welded to the inner door panel reinforcing plate, and the upper part of the reinforcing plate is positioned at the notch and inserted into the glass groove.

[0014] The mounting plate is welded to the glass guide rail.

[0015] Furthermore, the reinforcing plate and the mounting plate are arranged intersectingly; and / or,

[0016] The reinforcing plate and the mounting plate are integrally formed.

[0017] Furthermore, the reinforcing plate is provided with a first mounting portion, which is used to mount the triangular plate of the frameless door; and / or,

[0018] The door sheet metal assembly is provided with a second mounting part, which is used to install the triangular plate of the frameless door.

[0019] Furthermore, the reinforcing plate is provided with reinforcing ribs; and / or,

[0020] The mounting plate extends along the length of the glass guide rail.

[0021] Furthermore, in the left-right direction of the vehicle, the lower and upper parts of the reinforcing plate are arranged in a stepped manner.

[0022] Furthermore, a limiting structure is provided between the door sheet metal assembly and the glass groove, the limiting structure being able to limit the installation position of the glass groove on the door sheet metal assembly.

[0023] Compared with related technologies, this application has the following advantages:

[0024] (1) The door structure described in this application, by setting a reinforcing part, which is connected between the door sheet metal assembly and the glass guide rail, can improve the connection strength between the door sheet metal assembly and the glass guide rail, and can improve the stability and reliability of the reinforcing part installation. At the same time, by placing the reinforcing part at the notch, the structure of the notch part can be strengthened. Since the notch is located inside the glass groove, the reinforcing part can improve the structural strength of the glass groove support by strengthening the notch part, which can better prevent the glass groove from deforming, thereby improving the sealing performance and reducing the risk of wind noise and rain leakage.

[0025] (2) The door sheet metal assembly includes the door inner panel and the door inner panel reinforcement plate, which can better ensure the structural strength of the door sheet metal assembly. The glass guide rail and the reinforcement are both set on the outside of the door inner panel reinforcement plate, which makes it convenient for the reinforcement to be connected to the glass guide rail and the door inner panel reinforcement plate at the same time.

[0026] (3) The reinforcement includes a reinforcing plate and a mounting plate. The lower part of the reinforcing plate is welded to the inner door panel reinforcement plate, which provides a stable foundation for the installation of the reinforcement. The welding process ensures a strong connection between the two, effectively transferring stress and making the reinforcing plate and the inner door panel reinforcement plate a whole, jointly bearing the various forces experienced by the door during use. The upper part of the reinforcing plate is inserted into the glass groove, which can better support the glass groove, thereby preventing deformation of the glass groove and the risks caused by deformation. The mounting plate is welded to the glass guide rail, so that the reinforcement is firmly fixed between the door sheet metal assembly and the glass guide rail, which can better strengthen the structural strength of the notch area.

[0027] (4) The reinforcing plate and the mounting plate are arranged at intersections, forming a cross-support structure in different directions. When the door is subjected to external forces, such as collision forces or closing impact forces, the stress can be dispersed and transmitted along the two intersecting directions. This dispersion method can avoid excessive stress concentration in a single direction, thereby improving the load-bearing capacity of the entire structure and thus improving the support effect on the glass groove. The reinforcing plate and the mounting plate are integrally formed, making the reinforcing plate and the mounting plate a continuous and complete structure, without the connection gaps and stress concentration points caused by welding, bolting, etc. in traditional connection methods. This integral structure can more evenly disperse and transmit the various forces subjected to the door, thereby effectively improving the structural strength and deformation resistance of the door.

[0028] (5) A first mounting part is provided on the reinforcing plate. The first mounting part is used to install the triangular plate of the frameless door. It can provide a stable and reliable mounting base for the triangular plate and effectively transfer the force borne by the triangular plate to the reinforcing plate and even the entire door structure. A second mounting part is provided on the door sheet metal assembly. The second mounting part is used to install the triangular plate of the frameless door. During the vehicle's operation, the triangular plate will be subjected to various forces such as wind force and vibration. These forces can be transferred to the door sheet metal assembly through the triangular plate, so that the door sheet metal assembly can also provide a stable and reliable mounting base for the triangular plate, thereby improving the structural strength and reliability of the triangular plate area.

[0029] (6) Setting reinforcing ribs on the reinforcing plate can significantly improve the structural strength of the reinforcing plate itself, thereby improving the ability of the reinforcing plate to resist bending deformation. By improving the structural strength of the reinforcing plate itself, the reinforcement effect on the notch area can be improved on the one hand, and the structural strength of the connection between the door sheet metal assembly and the glass guide rail can also be improved on the other hand.

[0030] The mounting plate extends along the length of the glass guide rail, increasing the contact area between the mounting plate and the glass guide rail. This allows for more welding points, improving the connection reliability between the mounting part and the glass guide rail. Simultaneously, the increased contact area between the mounting plate and the glass guide rail enables the mounting plate to evenly distribute the load it receives, better preventing stress concentration. This enhances the deformation resistance of the glass guide rail, thereby improving the overall stability of the door structure.

[0031] (7) In the left and right direction of the whole vehicle, the upper and lower parts of the reinforcing plate are arranged in a stepped manner, which can form a staggered arrangement, making the structural strength of the reinforcing plate itself higher and further improving the support effect on the glass groove.

[0032] (8) A limiting structure is set between the door sheet metal assembly and the glass groove. The limiting structure can limit the installation position of the glass groove on the door sheet metal assembly, which can improve the installation accuracy of the glass and prevent the sealing failure or abnormal noise caused by the glass displacement during the lifting and lowering. At the same time, during the assembly process of the glass groove and the door sheet metal assembly, the limiting structure helps to improve the installation speed of the glass groove on the door sheet metal assembly and facilitates the quick and efficient finding of the installation position of the glass groove.

[0033] Another object of this application is to provide a car door having the door structure described above.

[0034] The door of this application, by applying the above door structure, can effectively improve the structural strength of the triangular plate area. The use of this door structure makes the glass groove less prone to deformation, effectively reduces wind noise, and reduces the risk of water leakage in rainy weather.

[0035] Meanwhile, another object of this application is to provide a vehicle having doors as described above.

[0036] The vehicle described in this application, by employing the aforementioned door structure, improves the vehicle's impact resistance and sealing performance, thereby enhancing the vehicle's quality and operational safety and reliability. Attached Figure Description

[0064] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0065] An embodiment of the first aspect of this application provides a car door structure that, by improving the specific structure of the car door, makes the glass groove less prone to deformation, thereby reducing wind noise and the risk of rain leakage in that area.

[0066] As a key structural element of automobiles, car doors not only provide convenience for passengers to get in and out of the vehicle, but also have a significant impact on the overall structural safety, sealing, and noise reduction of the vehicle. Frameless doors, as an innovative breakthrough in automotive design, offer numerous significant advantages beyond just providing a unique entry and exit experience and having potential impacts on overall structural safety, sealing, and noise reduction.

[0067] For example, from an aesthetic point of view, frameless doors greatly enhance the appearance of a car. In terms of aerodynamics, the clean structure of frameless doors helps reduce air resistance. Furthermore, frameless doors can also improve interior lighting and visibility to some extent.

[0068] The existing frameless car doors have triangular panels located mainly on both sides of the front and rear bumpers, below the doors, or in the fender area. They are mostly triangular or trapezoidal in shape and are generally matched with the glass grooves to seamlessly connect with the door and other structures, forming the streamlined appearance of the car body.

[0069] The existing frameless doors have the following problems: the glass channel area is prone to deformation, has poor sealing performance, and poses risks of high noise and water leakage when rained on. The root causes are likely multifaceted. For example, in terms of materials, the materials used in the glass channel may have quality defects or insufficient performance. In terms of design, the glass channel may not have adequately considered various working conditions and stresses in actual use. These factors can all contribute to significant wind noise in the glass channel area and even potential water leakage when rained on.

[0070] In view of this, to overcome the shortcomings of related technologies, the door structure of this embodiment improves the structural strength of the glass groove by modifying the structure of the components that mate with the glass groove, thereby reducing wind noise and the risk of water leakage from rain. It should be noted that the door structure of this embodiment is mainly applied to frameless doors.

[0071] In the door structure of this embodiment, combined with Figures 1 to 4 As shown, the overall design includes a door sheet metal assembly 1 and a glass guide rail 2 connected to one side of the door sheet metal assembly 1. In addition, the door structure also includes a reinforcing part 3 connecting the door sheet metal assembly 1 and the glass guide rail 2.

[0072] It should be noted that the structures of the door sheet metal assembly 1 and the glass guide rail 2 can both refer to the structures in related technologies. The door structure of this embodiment does not require modification of the existing door structure; only the reinforcing part 3 needs to be added to the existing structure. This helps to reduce production costs and the investment required for structural modifications, while effectively improving the existing problems of wind noise and water leakage.

[0073] Reference Figures 2 to 4 As shown, the door sheet metal assembly 1 has a first insertion part 10A that inserts into the glass groove 4 of the frameless door, and the glass guide rail 2 has a second insertion part 20A that inserts into the glass groove 4. A notch E is provided between the first insertion part 10A and the second insertion part 20A, and the aforementioned reinforcing part 3 is blocked at the notch E.

[0074] The door structure described in this embodiment, by providing a reinforcing part 3, which is connected between the door sheet metal assembly 1 and the glass guide rail 2, can effectively improve the connection strength between the door sheet metal assembly 1 and the glass guide rail 2, and can also improve the stability and reliability of the installation of the reinforcing part 3. At the same time, by placing the reinforcing part 3 at the notch E, the structure of the notch E area can be effectively strengthened. Since the notch E is located inside the glass groove 4, the reinforcing part 3 can improve the structural strength supporting the glass groove 4 by strengthening the notch E area, which can effectively prevent the glass groove 4 from deforming, thereby improving the sealing performance and reducing the risk of wind noise and rain leakage.

[0075] To ensure the structural strength of the door, in some exemplary embodiments, the door sheet metal assembly 1 includes an inner door panel 101 and an inner door panel reinforcing plate 102 connected to the outside of the inner door panel 101. The glass guide rail 2 and the reinforcing part 3 are both connected to the outside of the inner door panel reinforcing plate 102.

[0076] The door sheet metal assembly 1 includes a door inner panel 101 and a door inner panel reinforcing plate 102, which can better ensure the structural strength of the door sheet metal assembly 1. The glass guide rail 2 and the reinforcing part 3 are both set on the outside of the door inner panel reinforcing plate 102, so that the reinforcing part 3 can be connected to both the glass guide rail 2 and the door inner panel reinforcing plate 102 at the same time.

[0077] It should be noted that, in order to ensure structural strength, for example... Figure 2 As shown, in some examples, the lower part of the reinforcing part 3 is connected to the door inner panel reinforcing plate 102 and the glass guide rail 2 respectively. The lower part of the reinforcing part 3 serves as the mounting base for the reinforcing part 3, which not only ensures the stability and reliability of the installation of the reinforcing part 3, but also improves the reliability of the connection between the glass guide rail 2 and the door inner panel reinforcing plate 102.

[0078] Furthermore, the upper part of the reinforcing plate 301 is positioned to block the notch E between the first insertion part 10A and the second insertion part 20A, which can prevent the structural strength of the notch E from being poor. Here, by blocking the notch E with the upper part of the reinforcing plate 301, the structural strength of the notch E can be significantly improved.

[0079] Reference Figure 3 As shown, in one example, the notch E between the first insertion part 10A and the second insertion part 20A is roughly triangular, and the upper shape of the reinforcing plate 301 is consistent with the shape of the notch E. The amount of material used is small, and it can achieve a good reinforcing effect.

[0080] Continue to refer to Figure 3 The structure shown has an acute angle at the top of the first insertion part 10A and an included angle of nearly 90° at the top of the second insertion part 20A. The included angle between the two sides and the numerical direction of this included angle is between 30° and 60°. This arrangement facilitates the smooth insertion of the first insertion part 10A and the second insertion part 20A into the glass groove 4, thereby improving assembly efficiency.

[0081] like Figure 5 and Figure 6 As shown, in some exemplary embodiments, the reinforcing part 3 includes a reinforcing plate 301 and a mounting plate 302 connected to one side of the reinforcing plate 301. The lower part of the reinforcing plate 301 is welded to the inner door panel reinforcing plate 102, and the upper part of the reinforcing plate 301 is positioned at the notch E and inserted into the glass groove 4. The mounting plate 302 is welded to the glass guide rail 2.

[0082] In the above structure, the reinforcing part 3 includes a reinforcing plate 301 and a mounting plate 302. The lower part of the reinforcing plate 301 is welded to the inner door panel reinforcing plate 102, providing a stable foundation for the installation of the reinforcing part 3. The welding process ensures a strong connection between the two, effectively transferring stress and making the reinforcing plate 301 and the inner door panel reinforcing plate 102 a single unit, jointly bearing the various forces experienced by the door during use. The upper part of the reinforcing plate 301 is inserted into the glass groove 4, providing good support for the glass groove 4 and preventing deformation of the glass groove 4 and the risks associated with deformation. The mounting plate 302 is welded to the glass guide rail 2, ensuring that the reinforcing part 3 is securely fixed between the door sheet metal assembly 1 and the glass guide rail 2, effectively strengthening the structural strength of the notch E.

[0083] To improve the structural strength of the reinforcing part 3 itself, in some exemplary embodiments, the reinforcing plate 301 and the mounting plate 302 are arranged intersectingly. As in this embodiment, the reinforcing plate 301 and the mounting plate 302 are arranged orthogonally. It should be understood that it is also possible to provide other non-zero included angles between the reinforcing plate 301 and the mounting plate 302.

[0084] In the above embodiment, the reinforcing plate 301 and the mounting plate 302 are arranged intersectingly, forming a cross-support structure in different directions. When the door is subjected to external forces, such as collision forces or closing impact forces, the stress can be dispersed and transmitted along the two intersecting directions. This dispersion method avoids excessive stress concentration in a single direction, thereby improving the load-bearing capacity of the entire structure and thus improving the support effect on the glass groove 4.

[0085] Here, by orthogonally arranging the reinforcing plate 301 and the mounting plate 302, not only can the structural strength of the reinforcing part 3 itself be improved, but also the connection reliability between the door sheet metal assembly 1 and the glass guide rail 2 can be improved by increasing the structural strength of the reinforcing part 3. On the other hand, the reinforcement effect on the notch E can be improved, thereby better preventing the deformation of the glass groove 4.

[0086] It should be understood that the first insertion part 10A, the second insertion part 20A, and the upper part of the reinforcing plate 301 inserted into the glass groove 4 are equivalent to the skeleton structure of the glass groove 4. The door structure of this application strengthens these skeleton structures of the glass groove 4 to better prevent the glass groove 4 from deforming, thereby reducing wind noise and the risk of rain leakage.

[0087] In some exemplary embodiments, the reinforcing plate 301 and the mounting plate 302 are integrally formed. As in this embodiment, the reinforcing plate 301 and the mounting plate 302 are made from a single sheet of material, meaning the reinforcing part 3 is made from a single sheet of material, which can be achieved using sheet metal processing or casting. This facilitates processing and better ensures the structural strength of the reinforcing part 3, thereby improving the support and reinforcement effect on the glass groove 4.

[0088] In the exemplary embodiment described above, the reinforcing plate 301 and the mounting plate 302 are integrally formed, making them a continuous and complete structure. This eliminates the connection gaps and stress concentration points caused by welding, bolting, etc., in traditional connection methods. This integral structure can more evenly distribute and transmit the various forces acting on the door, thereby effectively improving the structural strength and deformation resistance of the door.

[0089] Continue to refer to Figure 5 and Figure 6 As shown, in some exemplary embodiments, the reinforcing plate 301 is provided with a first mounting portion 3011 for mounting the triangular plate 5 of the frameless door. Preferably, the first mounting portion 3011 is specifically an opening provided on the reinforcing plate 301. In a specific embodiment, the opening is a strip-shaped hole that extends along the vertical direction of the entire vehicle to facilitate the installation of the triangular plate 5.

[0090] It should be noted that in the above exemplary embodiment, a first mounting part 3011 is provided on the reinforcing plate 301. The first mounting part 3011 is used to install the triangular plate 5 of the frameless car door, which can provide a stable and reliable mounting base for the triangular plate 5 and effectively transfer the force borne by the triangular plate 5 to the reinforcing plate 301 and even the entire car door structure.

[0091] Here, through reasonable structural design, the first mounting part 3011 can ensure that the triangle plate 5 can maintain a fixed position under various working conditions and will not loosen or deform due to force, thereby ensuring the normal use function of the triangle plate 5.

[0092] In some exemplary embodiments, the door sheet metal assembly 1 is provided with a second mounting portion 10B for mounting the triangular plate 5 of the frameless door. In a preferred embodiment, the second mounting portion 10B specifically adopts a circular hole, and both the inner door panel 101 and the inner door panel reinforcing plate 102 are provided with this circular hole. The circular holes on the inner door panel 101 and the inner door panel reinforcing plate 102 are concentrically arranged and of the same size, which facilitates the installation of the triangular plate 5.

[0093] Here, a second mounting part 10B is provided on the door sheet metal assembly 1. The second mounting part 10B is used to install the triangular plate 5 of the frameless door. During the vehicle's operation, the triangular plate 5 will be subjected to various forces such as wind and vibration. These forces can be transmitted to the door sheet metal assembly 1 through the triangular plate 5, so that the door sheet metal assembly 1 can also provide a stable and reliable mounting base for the triangular plate 5, thereby improving the structural strength and reliability of the triangular plate 5 area.

[0094] To improve the structural strength of mounting plate 302, continue to refer to Figure 5 and Figure 6 As shown, in some exemplary embodiments, the reinforcing plate 301 is provided with reinforcing ribs 3012. For example Figure 5 and Figure 6 The structure shown has a portion of the reinforcing ribs 3012 with the same shape as the upper edge of the first insertion part 10A, and extending in the direction of the upper edge of the first insertion part 10A. Another portion of the reinforcing ribs 3012 extends obliquely upward, which can improve the structural strength of the mounting plate 302.

[0095] It should be understood that setting reinforcing ribs 3012 on reinforcing plate 301 can significantly improve the structural strength of reinforcing plate 301 itself, thereby improving the ability of reinforcing plate 301 to resist bending deformation. By improving the structural strength of reinforcing plate 301 itself, the reinforcement effect on the notch E area can be improved on the one hand, and the structural strength of the connection between door sheet metal assembly 1 and glass guide rail 2 can also be improved.

[0096] Continue to refer to Figure 2 and Figure 3 and combined Figure 5 and Figure 6 As shown, in some exemplary embodiments, the mounting plate 302 extends along the length of the glass guide rail 2. For example... Figure 6 As shown, the mounting plate 302 is rectangular with rounded corners on all four sides to better prevent stress concentration.

[0097] In this embodiment, the mounting plate 302 extends along the length of the glass guide rail 2, which increases the contact area between the mounting plate 302 and the glass guide rail 2. This allows for the arrangement of more welding points, thereby improving the connection reliability between the mounting part and the glass guide rail 2. Simultaneously, the increased contact area between the mounting plate 302 and the glass guide rail 2 also enables the mounting plate 302 to evenly distribute the load it receives, effectively preventing stress concentration. This enhances the deformation resistance of the glass guide rail 2, thereby improving the stability of the entire door structure.

[0098] Still refer to Figure 2 and Figure 3 As shown, in some exemplary embodiments, the glass guide rail 2 includes a first plate 201 and a second plate 202, and a connecting plate 203 connecting the first plate 201 and the second plate 202. The first plate 201 and the second plate 202 are each provided with a second insertion part 20A.

[0099] Depend on Figure 2 and Figure 3 Combination Figure 7 As shown, for example in this application, the second insertion portion 20A on the first plate 201 and the second plate 202 is a pointed shape, which makes the first plate 201 and the second plate 202 inserted into the glass lining groove 4 more in number and more matched with the shape of the glass lining groove 4, which can better improve the structural strength of the upper angle portion of the glass lining groove 4.

[0100] like Figure 7 In the glass groove 4, there is an insert 403 with a cross-sectional shape of a horizontal "U". When the glass guide rail 2 is inserted into the insertion slot 402 of the glass groove 4, the insert 403 is inserted into the groove formed by the first plate 201, the second plate 202 and the connecting plate 203 of the glass guide rail 2, thereby improving the stability and reliability of the glass groove 4.

[0101] In addition, the glass guide rail 2 includes a first plate 201 and a second plate 202. The double plate structure can form the main bearing surface of the guide rail. The connecting plate 203 serves as a transition structure between the first plate 201 and the second plate 202, which allows the glass guide rail 2 to form a continuous and complete integral structure, making the glass guide rail 2 lighter and stronger. The first plate 201 and the second plate 202 are both provided with second insertion parts 20A, which can better improve the support effect on the glass groove 4. The two second insertion parts 20A simultaneously support the sharp corner area of ​​the glass groove 4, which can better prevent the glass groove 4 from deforming and improve the reinforcement effect on the glass groove 4.
