Description

Technical Field

[0001] This application relates to the field of vehicle component technology, specifically to a door structure and a vehicle. Background Technology

[0002] The acoustic quality of car doors directly impacts user experience, with the core issue being the modal frequencies of the outer door panel. Traditional outer panel support plates are often long and thin strips, spanning approximately 1 meter. However, due to internal space limitations and narrow cross-sectional dimensions, their structural rigidity is insufficient, failing to effectively suppress vibrations. This results in low modal frequencies and poor acoustic performance for the car door. Furthermore, traditional support plates are spot-welded to the inner door panel, which not only exposes the welds, affecting aesthetics, but also leads to stress concentration due to the discrete connection method. This makes it difficult to form a continuous and efficient force transmission path, further limiting the support plate's support effectiveness and durability. Utility Model Content

[0019] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0020] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0021] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] With the deepening development of the automotive industry and the increasingly sophisticated demands of consumers, the vehicle performance evaluation system has expanded from basic safety, power and energy consumption to a more refined level of sensory experience, among which the acoustic quality of car doors is a key indicator.

[0023] When a car door is closed or vibrated while driving, the modal frequency of the outer door panel directly determines the sound quality. Low-frequency or easily excited modes will result in a loose and cheap auditory experience, affecting the user's perception and evaluation of the overall quality of the vehicle.

[0024] In related technologies, in the past vehicle designs, the outer door panel support plate generally adopted a simple long strip structure with a span of about one meter. However, due to the space limitations of components such as the door lifter, the cross-sectional depth of the support plate was usually only about ten millimeters, and the cross-sectional width was about forty millimeters.

[0025] The slender and thin beam-like structure of the support plate inherently suffers from insufficient structural stiffness, failing to provide solid and uniform support for the large-area exterior door panels. Furthermore, the exterior door panels are more prone to localized vibrations under dynamic excitation, resulting in lower modal frequencies and thus deteriorating acoustic performance.

[0026] Furthermore, traditional support plates are typically connected to the inner door panel by spot welding. This process not only leaves visible weld points on the surface of the inner door panel, compromising the aesthetics and cleanliness of the door cavity and reducing its appearance quality, but also, as a discrete connection method, spot welding is prone to stress concentration around the weld points, posing a fatigue risk over long-term use. In addition, it fails to establish an efficient and continuous force transmission path between the support plate and the outer door panel.

[0027] In order to solve the above-mentioned technical problems and technical considerations, the embodiments of this application provide a door structure and a vehicle. The door structure can provide better support for the outer door panel, resulting in higher structural strength and modal frequency of the outer door panel, thereby improving the door's shape adaptability, structural strength and acoustic quality.

[0028] The following will combine Figures 1 to 9 The door structure and vehicle provided in the embodiments of this application will be further described in detail.

[0029] Figure 1 This illustration shows a portion of the structure of the door structure 100 provided in the first aspect embodiment of this application. Figure 2 Another part of the structure of the door structure 100 provided in the first aspect embodiment of this application is shown.

[0030] Please see Figures 1 to 2 In one aspect, embodiments of this application provide a door structure 100, including an inner door panel 100b, an outer door panel 100a, a crash beam 10, a window frame reinforcing plate 20, and an outer panel support plate 30.

[0031] An accommodating space is defined between the inner door panel 100b and the outer door panel 100a.

[0032] The anti-collision beam 10 is located within the accommodating space and is fixedly connected to the outer door panel 100a and the inner door panel 100b respectively.

[0033] The window frame reinforcement plate 20 is located within the accommodating space and is fixedly connected to the outer door panel 100a and the inner door panel 100b respectively.

[0034] The outer panel support plate 30 is located within the accommodating space and is bonded to the outer door panel 100a. The outer panel support plate 30 includes at least one first branch 31 and at least two second branches 32 extending outwards. The end of the first branch 31 away from the second branch 32 is fixedly connected to the window frame reinforcing plate 20, and the end of the second branch 32 away from the first branch 31 is fixedly connected to the anti-collision beam 10.

[0035] The door structure 100 provided in the first aspect of this application, through the multi-branch shape of the outer panel support plate 30 including the first branch 31 and the second branch 32, spans the main body area of ​​the door and is fixedly connected to the window frame reinforcing plate 20 and the anti-collision beam 10 respectively, effectively improving the support effect and reducing the space occupied in the accommodating space; and the outer panel support plate 30 and the outer panel 100a of the door are fixed by adhesive bonding, avoiding the existence of weld points that affect the aesthetics and achieving the basic fixing effect, while effectively optimizing the transmission path of vibration energy, thereby effectively improving the door's shape adaptability, structural strength and acoustic quality.

[0036] The outer panel support plate 30 adopts a unique extended structure including at least one first branch 31 and at least two second branches 32, so that the outer panel support plate 30 itself forms a stable multi-branch shape. The first branch 31 is fixedly connected to the window frame reinforcement plate 20 located at the upper part of the door, while the second branch 32 is fixedly connected to the anti-collision beam 10 located in the middle of the door, thereby constructing a multi-point support frame spanning the main body area of ​​the door in the vertical direction of the door.

[0037] The layout of the outer panel support plate 30 greatly shortens the effective span of the outer panel support plate 30, transforming the traditional strip support that is about one meter long into a compact support, which directly and effectively improves the structural rigidity and bending resistance of the outer panel support plate 30 body, and reduces the space occupied.

[0038] Furthermore, the increased stiffness of the outer panel support plate 30 enables it to provide more solid and uniform support for the outer door panel 100a, suppressing local vibrations of the outer door panel 100a under dynamic excitation. This results in an increase in the overall modal frequency of the outer door panel 100a, thereby improving the acoustic quality of the door, eliminating the loose and cheap auditory experience caused by excessively low modal frequencies, and enhancing the user's sensory experience.

[0039] Furthermore, the outer panel support plate 30 is fixed to the outer door panel 100a by adhesive bonding. This change in the connection method between the outer panel support plate 30 and the outer door panel 100a eliminates the need for spot welding on the inner door panel 100b, as required by traditional solutions. This avoids the problem of reduced aesthetics inside the door cavity due to exposed weld points, thus improving the overall appearance quality of the vehicle.

[0040] Meanwhile, the adhesive connection between the outer panel support plate 30 and the outer door panel 100a forms a large-area, continuously distributed force transmission interface. Compared with discrete spot welding connections, it can transmit the supporting force of the outer panel support plate 30 on the outer door panel 100a and the external impact load more smoothly and evenly, avoiding stress concentration. This not only improves the structural durability of the outer panel support plate 30, but also further optimizes the transmission path of vibration energy, which has a positive effect on improving the acoustic quality of the door.

[0041] A space is formed between the inner door panel 100b and the outer door panel 100a to accommodate more protective and supporting structures. The anti-collision beam 10 is used to support and protect the door structure 100 when it is impacted, while the window frame reinforcement plate 20 is used to further reinforce the window frame in the door structure 100.

[0042] For example, in the first aspect embodiment of this application, the outer panel support plate 30 presents a "Y" shape, including a first branch 31 and two second branches 32. The outer panel support plate 30 adopts an innovative structure that connects the window frame reinforcing plate 20 and the anti-collision beam 10 with a "Y" shaped multi-branch support plate, and combined with the outer panel bonding process, it achieves the beneficial effects of enhancing structural rigidity, increasing modal frequency, improving acoustic quality, optimizing force transmission path, and improving appearance quality.

[0043] For example, the outer support plate 30 has a span length of 490mm to 510mm, resulting in a compact and high-strength structure.

[0044] Figure 3 It shows Figure 1 The separate structure of the outer support plate 30 in the middle. Figure 4 It shows Figure 3 The cross-sectional structure along the AA direction.

[0045] For example, please refer to Figure 3 and Figure 4 The first support 31 and the second support 32 of the outer plate support plate 30 adopt a support shape with a "U" cross section. Two reinforcing ribs are formed through the length of the first support 31 and the second support 32 to further enhance the structural strength of the outer plate support plate 30.

[0046] Please see Figures 1 to 3 In some embodiments, both the first branch 31 and the second branch 32 include a main body 30a and mounting ears 30b arranged alternately along the edge of the main body 30a, the mounting ears 30b being bonded to the outer door panel 100a.

[0047] In these embodiments, the force transmission efficiency and connection reliability between the outer panel support plate 30 and the outer panel 100a are further optimized by fixing the mounting ear 30b to the outer panel 100a of the door through adhesive bonding.

[0048] The main body 30a serves as the primary load-bearing and force-transmitting frame, providing the basic structural rigidity for the entire support.

[0049] The mounting ears 30b, which are alternately distributed along the edge of the main body 30a, increase the effective bonding area and bonding point distribution density between the outer panel support plate 30 and the door outer panel 100a without compromising the structural strength of the main body 30a.

[0050] The alternating arrangement of mounting ears 30b makes the distribution of adhesive force more uniform and reasonable, which not only ensures the connection strength, but also avoids local stress concentration and improves structural durability.

[0051] From the perspective of vibration control, the distributed adhesive interface of the mounting ear 30b can more effectively suppress and disperse the in-plane vibration of the door outer panel 100a, and transmit the support effect to a larger area of ​​the door outer panel 100a in a more continuous and smooth manner, thereby more effectively improving the overall modal frequency of the door outer panel 100a and playing a positive role in improving the acoustic quality of the door.

[0052] Meanwhile, the back-side bonding process using the mounting ear 30b completely hides it inside the outer door panel 100a, ensuring a secure connection while maximizing the visual cleanliness and aesthetics of the interior space.

[0053] For example, the cross-sectional shape of the main body 30a is "U" shaped, which further ensures that the main body 30a can provide basic structural strength.

[0054] Figure 5 It shows Figure 2 Cross-sectional structure along the BB direction.

[0055] Please see Figure 5 In some embodiments, the door structure 100 further includes an adhesive portion 40 located between the outer panel support plate 30 and the outer door panel 100a. The mounting ear 30b is bonded to the outer door panel 100a through the adhesive portion 40, which is an expanding adhesive.

[0056] In these embodiments, the use of an adhesive portion 40 made of an expandable material between the mounting lug 30b of the outer panel support plate 30 and the outer door panel 100a further optimizes the connection performance and structural integrity.

[0057] The expanding adhesive has good filling properties when initially applied, and can fully cover the bonding surface of the mounting ear 30b. During the subsequent painting and drying process, it expands due to heat, and the volume of the expanding adhesive will increase in a controllable manner, thereby tightly filling the assembly gap that may exist between the outer panel support plate 30 and the outer door panel 100a, forming a composite interface that combines connection, sealing and buffering functions.

[0058] The adhesive portion 40 not only provides reliable bonding strength, but also effectively transfers the supporting effect of the outer panel support plate 30 to the door outer panel 100a through the mounting ear 30b. The continuous interfacial pressure generated after the adhesive portion 40 expands further enhances the stability of the connection.

[0059] Meanwhile, as a damping material, the expanding adhesive can effectively attenuate and absorb the vibration energy transmitted from the outer door panel 100a, further suppressing resonance and playing a positive auxiliary role in improving the acoustic quality of the door.

[0060] In addition, the integrated bonding and sealing between the mounting ear 30b and the outer door panel 100a also enhances the sealing performance of the interior of the door cavity, improving the structural rigidity, durability and acoustic quality of the door structure 100.

[0061] Figure 6 It shows Figure 2 The enlarged structure of region C in the middle.

[0062] Please see Figure 6 In some embodiments, the end of the first branch 31 away from the second branch 32 is riveted to the window frame reinforcing plate 20.

[0063] In these embodiments, the first branch 31 is fixedly connected to the window frame reinforcing plate 20 by riveting at the end away from the second branch 32, which further enhances the stability and reliability of the upper support structure of the door.

[0064] Riveting, as a mechanical fastening method, can form a strong and reliable connection node between the first support 31 and the window frame reinforcing plate 20, effectively bearing the vibration load and static stress transmitted from the outer door panel 100a. Compared with traditional welding processes, riveting has a low heat input, effectively avoiding changes or deformations in the metal material structure caused by high temperatures. It is especially suitable for the connection between aluminum components, which helps maintain the stability of the structural dimensions and the original properties of the material.

[0065] The riveting node and the connection point between the second branch 32 of the aforementioned outer panel support plate 30 and the anti-collision beam 10 cooperate to form a complete force transmission closed loop, which enables the load from different areas of the door to be dispersed and transmitted, improves the structural stiffness of the upper area of ​​the door, especially near the window frame, and can more effectively suppress vibration. It also has a positive effect on improving the overall modal frequency of the outer panel 100a of the door and further optimizing the acoustic quality.

[0066] Please continue reading. Figure 6 In some embodiments, the end of the first branch 31 away from the second branch 32 is riveted to the window frame reinforcing plate 20 by at least two rivets.

[0067] In these embodiments, the end of the first branch 31 away from the second branch 32 is riveted and fixed to the window frame reinforcing plate 20 by at least two rivets. Through the reasonable layout of multiple rivet points, a more stable and reliable mechanical connection is established between the first branch 31 and the window frame reinforcing plate 20.

[0068] Multiple rivets share the load in the connection area, effectively avoiding stress concentration that may occur with single-point connections, and improving the fatigue resistance and long-term reliability of the connection node.

[0069] The multi-point riveting method allows vibration loads and external impact forces from the outer door panel 100a to be transmitted more evenly to the window frame reinforcing plate 20 through the first support 31, thereby distributing them throughout the upper structure of the door and enhancing the local stiffness and overall stability of the window frame area. Compared with single-point connection, the multi-point riveting design provides stronger resistance to torsion and bending, ensuring that the outer panel support plate 30 provides more sufficient and durable support for the outer door panel 100a, especially the upper window frame area.

[0070] Meanwhile, the multi-point riveting and the bonding scheme between the aforementioned outer panel support plate 30 and the outer door panel 100a work together to construct a composite connection system. While ensuring structural strength, it optimizes the transmission and attenuation path of vibration energy, thereby improving the structural integrity, durability and overall acoustic quality of the door structure 100.

[0071] Figure 7 It shows Figure 2 The magnified structure of region D in the middle Figure 8 It shows Figure 7 Cross-sectional structure along the EE direction.

[0072] Please see Figure 7 and Figure 8 In some embodiments, the end of the second branch 32 away from the first branch 31 is riveted to the anti-collision beam 10.

[0073] In these embodiments, the second branch 32 is fixedly connected to the anti-collision beam 10 by riveting at the end away from the first branch 31, which further enhances the stability and reliability of the lower support structure of the door.

[0074] Riveting, as a mechanical fastening method, can form a strong and reliable connection node between the second support 32 and the anti-collision beam 10, effectively bearing the vibration load and static stress transmitted from the outer door panel 100a. Compared with traditional welding processes, riveting has a low heat input, effectively avoiding changes or deformations in the metal material structure caused by high temperatures. It is especially suitable for the connection between aluminum components, which helps maintain the stability of the structural dimensions and the original properties of the material.

[0075] The riveting joints and the connection points of the first branch 31 of the aforementioned outer panel support plate 30 and the window frame reinforcing plate 20 cooperate to form a complete force transmission closed loop, which enables the loads from different areas of the door to be distributed and transmitted, improves the structural stiffness of the lower part of the door, especially near the anti-collision beam 10, can more effectively suppress vibration, and also has a positive effect on improving the overall modal frequency of the outer panel 100a of the door and further optimizing the acoustic quality.

[0076] Please see Figure 3 In some embodiments, the first branch 31 and the second branch 32 include mounting holes 30c, which are located at the end of the first branch 31 away from the second branch 32 and the end of the second branch 32 away from the first branch 31.

[0077] For example, the first support 31 includes two mounting holes 30c with a diameter of 5.3 mm. Two alignment holes with a diameter of 6.2 mm are also opened at the pre-installation position of the window frame reinforcing plate 20. The mounting holes 30c of the first support 31 are riveted to the alignment holes by two pop rivets.

[0078] For example, the second branch 32 includes a mounting hole 30c with a diameter of 6.2 mm, and two alignment holes with a diameter of 5.3 mm are opened corresponding to the pre-installation positions of the two second branches 32 on the anti-collision beam 10. The mounting hole 30c of the second branch 32 is riveted to the alignment hole by two pop rivets.

[0079] Please continue reading. Figure 3 In some embodiments, at least one first branch 31 and the second branch 32 further include a positioning hole 30d located around the mounting hole 30c.

[0080] In these embodiments, the positioning hole 30d enables the first support 31, the second support 32 to be aligned with the anti-collision beam 10 and the window frame reinforcing plate 20 in their pre-installation positions, and then the mounting hole 30c is used to install rivets to achieve riveting.

[0081] Please continue reading. Figure 3 In some embodiments, the main body 30a also includes a plurality of weight-reducing holes 30e that penetrate through itself and are spaced apart.

[0082] In these embodiments, the outer panel support plate 30 in the door structure 100 is further structurally optimized by opening weight reduction holes 30e, so as to further reduce the weight while ensuring structural strength, thereby further reducing the weight of the door structure 100.
