Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a sheet metal part for a vehicle body, a vehicle body, and a vehicle. Background Technology

[0002] Paint application and adhesive application are the primary sealing methods for welded seams in vehicle body panels. However, in some areas, paint application and adhesive application may be interrupted due to obstruction by parts. Therefore, it is necessary to seal these weld seams with body-mounted adhesive, which needs to form a closed-loop structure with the paint application to prevent water from leaking into the vehicle through the gap between the two. Traditional sheet metal welding edge structures and adhesive application methods cannot ensure effective bonding between the body-mounted adhesive and the paint application adhesive, leading to a risk of water leakage into the vehicle body. Utility Model Content

[0003] This application provides a sheet metal part of a vehicle body, a vehicle body, and a vehicle, for reducing the risk of water leakage when the sheet metal parts of the vehicle body are connected.

[0004] This application provides a sheet metal part for a vehicle body, the sheet metal part including a plate, the plate having a flange for welding, the edge of the flange having at least one notch, the notch being used for a first adhesive and a second adhesive applied to the plate to connect at the notch.

[0005] In this design, a notch is created on the flange of the sheet metal, allowing the first and second adhesives to converge over a large area at the notch, providing a larger contact area for their bonding. Furthermore, this ensures effective connection of the body panel components, and the stronger connection prevents water leakage into the vehicle interior, thereby reducing the risk of water leakage from the body panel components and improving the vehicle's sealing performance.

[0006] In one possible implementation, the depth of the notch is H, and the width of the flange is D, where H = (D / 2 - a) mm, and 2 mm ≤ a ≤ 4 mm.

[0007] In this design, the flange width results in a larger connection area between the two sheet metal parts to be welded, leading to higher connection reliability. When H = (D / 2 - a) mm and satisfies 2 mm ≤ a ≤ 4 mm, the notch depth H is moderate, increasing the connection area between the first and second adhesives at the notch location. At the same time, it does not cause overload of the flange strength, thus avoiding irreversible damage to the flange material.

[0008] In one possible implementation, the notch is V-shaped or inverted trapezoidal.

[0009] In this design, the notch shape allows for a larger opening area, increasing the bonding area between the first and second adhesives at the notch location without causing excessive deposition of the first adhesive within the notch, thus preventing waste. Furthermore, the V-shape or inverted trapezoidal shape optimizes the stress distribution on the material. When a large amount of the first adhesive is stored in the notch, and the contact area experiences compression deformation, stress concentration is effectively alleviated, protecting the connection structure. The V-shaped or inverted trapezoidal notch reduces the processing difficulty of manufacturing body sheet metal parts with notches, saving production costs.

[0010] In one possible implementation, the opening angle of the notch is α, where 45°≤α≤120°.

[0011] In this design, the opening angle α of the notch is moderate, providing a large contact area for the effective connection of the body sheet metal parts. At the same time, it avoids the waste of connection materials, that is, a tight connection with the second adhesive can be achieved by using an appropriate amount of the first adhesive.

[0012] In one possible implementation, the sheet metal part further includes a crossbeam disposed on the plate, and the notches are symmetrically disposed on both sides of the crossbeam.

[0013] In this design, symmetrically distributed notches are provided on both sides of the crossbeam, exposing the first adhesive at the notches. After the first adhesive is exposed, it connects with the second adhesive at the notch, ensuring that the connection between the first adhesive and the second adhesive forms a closed-loop structure, thereby ensuring the stability of the connection between the crossbeam and the plate.

[0014] In one possible implementation, the flange has multiple weld points, with the gap between the adjacent weld point closest to the position of the crossbeam.

[0015] In this design, the flanged weld points are used not only for welding the body sheet metal parts but also for positioning the application point of the first adhesive. The first adhesive is applied to the weld point and extends outwards from the center of the weld point. Furthermore, the first adhesive, due to its extension inertia, flows into the notch, thus connecting with the second adhesive and preventing the first adhesive from flowing into the notch. The notch is positioned between the nearest adjacent weld points to the crossbeam, ensuring that the notch does not impair the welding function. Moreover, the notch's proximity to the crossbeam maximizes the connection strength between the crossbeam and the sheet metal parts.

[0016] This application provides a vehicle body comprising multiple sheet metal parts, adjacent of which are welded together by a flange. The sheet metal parts are those described above. A first adhesive is provided on the end face of the flange along its thickness direction, and this first adhesive is exposed at the notch. A second adhesive is provided on the sidewall of the flange, and the first adhesive and the second adhesive are connected at the notch.

[0017] In this solution, the effective connection between the first adhesive and the second adhesive ensures the effective connection of the body sheet metal parts. Furthermore, the more robust connection of the sheet metal parts can prevent water from leaking into the vehicle, thereby reducing the risk of water leakage from the body sheet metal parts and improving the sealing performance of the vehicle body.

[0018] Furthermore, the first adhesive and the second adhesive form a point connection at the notch. This point connection increases the reliability of the connection by reducing overall stress concentration through localized contact. Point connections offer greater flexibility in layout, adapting to more complex surface environments. They also reduce material waste and processing difficulty, requiring only a small amount of the first adhesive to be applied at the notch where the first and second adhesives meet, thus avoiding material waste from large-area adhesive application. Additionally, point connections help reduce maintenance costs.

[0019] In one possible implementation, the distance between the first adhesive and the sidewall of the flange is L, L=D / 2, and L>H, where 16mm≤D≤18mm.

[0020] In this solution, the distance between the first adhesive and the weld point and the edge of the flange sidewall is moderate, that is, the distance of the first adhesive flowing to the notch is moderate. Without affecting the welding effect, the first adhesive can flow smoothly to the notch and converge with the second adhesive, which is conducive to improving the connection effect between the first adhesive and the second adhesive, and can also reduce the material waste of the first adhesive.

[0021] In one possible implementation, the sheet metal part further includes a crossbeam, the first adhesive is continuously disposed along the extension direction of the flange, the second adhesive is continuously disposed along the extension direction of the flange, and the second adhesive is interrupted at the position of the crossbeam.

[0022] In this design, the first adhesive is continuously applied along the extension direction of the flange, allowing two connected sheet metal parts to be joined by the continuous first adhesive, thus improving connection and sealing reliability. Simultaneously, the second adhesive is also continuously applied along the extension direction of the flange, but due to the obstruction of the crossbeam, the second adhesive is interrupted at the crossbeam location; that is, the second adhesive has a multi-segment structure, thereby avoiding the crossbeam and improving the structural strength of the vehicle body.

[0023] This application also provides a vehicle, which includes a chassis and a body, the body being mounted on the chassis, and the body being any of the body types described above.

[0042] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0044] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] In one specific embodiment, this application provides a vehicle, which includes a chassis and a body, the body being mounted on the chassis, the chassis providing mounting support for the body, and the body providing seating space for occupants.

[0047] The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle, etc. This application does not specify the type of vehicle.

[0048] In one specific embodiment, such as Figure 1 As shown, this application provides a vehicle body, which includes multiple sheet metal parts. The sheet metal parts of the vehicle body include a plate 1, as shown... Figures 3-5 As shown, the plate 1 is provided with a flange 11 for welding, and adjacent sheet metal parts are welded together through the flange 11 on the plate 1.

[0049] like Figure 5 and Figure 7 As shown, a first adhesive 3 is provided on the end face of the flange 11 along the thickness direction, and the first adhesive 3 is exposed at the notch 111. A second adhesive 4 is provided on the side wall of the flange 11, and the first adhesive 3 and the second adhesive 4 are connected at the notch 111.

[0050] In this embodiment, reference Figure 2As shown, the first adhesive 3 is disposed on the welding side of the flange 11, and the second adhesive 4 is disposed on one side wall of the flange 11. When the first adhesive 3 and the second adhesive 4 are connected on the flange 11 where there is no notch 111, a gap 5 exists between the first adhesive 3 and the second adhesive 4, resulting in low reliability of the connection between two adjacent sheet metal parts via adhesive. To solve this technical problem, such as... Figure 7 As shown, when the first adhesive 3 and the second adhesive 4 are connected at the notch 111, the first adhesive 3 is exposed at the notch 111, allowing the first adhesive 3 and the second adhesive 4 to be connected at the notch 111. That is, at the notch 111, there is no gap between the first adhesive 3 and the second adhesive 4, and the volume of the first adhesive 3 and the second adhesive 4 at the notch 111 is relatively large. This makes the connection reliability of the two adjacent sheet metal parts highly reliable when bonded by the first adhesive 3 and the second adhesive 4. Moreover, the connection of the two adjacent sheet metal parts can prevent water from leaking into the vehicle, thereby reducing the risk of water leakage from the sheet metal parts of the vehicle body and improving the sealing performance of the vehicle body.

[0051] The following describes in detail the connection steps between the first adhesive 3 and the second adhesive 4. First, refer to... Figure 3 As shown, notches 111 are provided on the flange 11, and the notches 111 are distributed in a dotted pattern along the flange 11, providing sufficient space for the connection between the first adhesive 3 and the second adhesive 4. (Reference) Figure 4 As shown, firstly, the first adhesive 3 is applied to the body sheet metal part. Specifically, the first adhesive 3 is applied to the side of the flange 11 used for welding. Finally, refer to... Figure 5 As shown, a second adhesive 4 is then applied to the body sheet metal parts. Specifically, the second adhesive 4 is applied to one side of the side wall of the flange 11. At this time, the first adhesive 3 and the second adhesive 4 are connected at the notch 111.

[0052] The point-type connection between the first adhesive 3 and the second adhesive 4 at the notch 111 increases the reliability of the connection and reduces stress concentration by localized contact. Point-type connection allows for more flexible layout and can adapt to more complex surface environments. Point-type connection reduces material waste and processing difficulty. A larger amount of the first adhesive 3 only needs to be applied at the notch 111, the contact point between the first adhesive 3 and the second adhesive 4, to achieve the connection purpose, avoiding material waste caused by continuous application of adhesive over a large area. Point-type connection also helps to reduce maintenance costs.

[0053] In this embodiment, the first adhesive 3 can be a car body adhesive, and the second adhesive 4 can be a coating adhesive.

[0054] In this embodiment, reference Figure 1As shown, the various sheet metal parts can specifically refer to the front bulkhead bracket, the body floor, and the door frame panels, etc. The connection of body sheet metal parts plays multiple crucial roles in the vehicle structure and is a core technology for achieving vehicle safety, functionality, and durability.

[0055] In one specific embodiment, reference is made to... Figure 6 As shown, the depth of the notch 111 is H, and the width of the flange 11 is D. H = (D / 2 - a) mm, where 2 mm ≤ a ≤ 4 mm. For example, a can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, etc.

[0056] Specifically, such as Figure 2 As shown, the width D of the flange 11 refers to the width of the welded edge and the welded surface when the sheet metal parts are connected.

[0057] In addition, preferably, the value of 'a' can be 3mm.

[0058] In this embodiment, under normal circumstances, the width of the flange 11 can be 16mm ≤ D ≤ 18mm. This width of flange 11 allows for a larger connection area between the two sheet metal parts being welded together, resulting in higher connection reliability. For example, the width D of the flange 11 can be 16mm, 16.5mm, 17mm, 17.5mm, 18mm, etc.

[0059] When the width D of the flange 11 is too small, the area that the flange 11 can provide for the first adhesive 3 in the width direction is too small. This area is prone to overflow or uneven application of adhesive, resulting in a small connection area between the two sheet metal parts that are welded together, which reduces the connection reliability of the first adhesive 3 on the flange 11. When the width D of the flange 11 is too large, the volume occupied by the flange 11 in the width direction is too large, which affects the compactness of the space for connecting the body sheet metal parts and causes a waste of cost in the manufacturing of the flange 11.

[0060] In this embodiment, the width D of the flange 11 satisfies 16mm≤D≤18mm. The width D of the flange 11 is moderate, providing sufficient application area for the first adhesive 3, which improves the connection area and connection reliability between the two sheet metal parts, reduces manufacturing costs, and improves the space utilization rate at the connection of the body sheet metal parts.

[0061] In some embodiments, the depth H of the notch 111 can be 5mm≤H≤7mm. For example, the depth H of the notch 111 can be 5mm, 5.5mm, 6mm, 6.5mm, 6.8mm, 7mm, etc.

[0062] When the depth H of the notch 111 is too small, the space where the first adhesive 3 and the second adhesive 4 converge in the notch 111 is too small, reducing the connection strength between the first adhesive 3 and the second adhesive 4; when the depth H of the notch 111 is too large, the space where the first adhesive 3 and the second adhesive 4 converge in the notch 111 is too large, which will cause the flange 11 to be overloaded, thereby causing irreversible damage to the material of the flange 11.

[0063] In this embodiment, when the depth H of the notch 111 can satisfy 5mm≤H≤7mm, the depth H of the notch 111 is moderate. It can increase the connection area between the first adhesive 3 and the second adhesive 4 at the notch 111 position, while not causing the strength of the flange 11 to be overloaded, thereby avoiding irreversible damage to the material of the flange 11.

[0064] In one specific embodiment, reference is made to... Figure 3 and Figure 6 As shown, the notch 111 is V-shaped or inverted trapezoidal.

[0065] In this embodiment, the notch 111 is V-shaped or inverted trapezoidal. This shape allows for a larger opening area, increasing the connection area between the first adhesive 3 and the second adhesive 4 at the notch 111, without causing excessive deposition of the first adhesive 3 within the notch 111, thus preventing waste. Furthermore, the V-shape or inverted trapezoidal shape optimizes the stress distribution on the material. When a large amount of the first adhesive 3 is stored in the notch 111, and the contact area of ​​the notch 111 undergoes compression deformation, stress concentration can be effectively alleviated, protecting the connection structure. The V-shaped or inverted trapezoidal notch 111 reduces the processing difficulty of manufacturing body sheet metal parts with notches 111, saving manufacturing costs.

[0066] In one specific embodiment, reference is made to... Figure 3 As shown, the opening angle of notch 111 is α, 45°≤α≤120°. For example, the opening angle α of notch 111 can be 45°, 50°, 60°, 80°, 90°, 100°, 110°, 120°, etc.

[0067] When the opening angle α of the notch 111 is too small, the first adhesive 3 and the second adhesive 4 will not easily enter the notch 111, which will result in the notch 111 being empty and affect the reliability of the connection between the first adhesive 3 and the second adhesive 4 at the notch 111 position. When the opening angle α of the notch 111 is too large, the first adhesive 3 and the second adhesive 4 cannot be concentrated and deposited at the notch 111 position, which will affect the reliability of the connection between the first adhesive 3 and the second adhesive 4 at the notch 111 position.

[0068] In this embodiment, the opening angle α of the notch 111 satisfies 45°≤α≤120°. The opening angle α of the notch 111 is moderate, allowing the first adhesive 3 and the second adhesive 4 to converge over a large area at the notch 111. This provides a larger contact area for the connection between the first adhesive 3 and the second adhesive 4, improving the reliability of the body panel connection. Simultaneously, it avoids waste of connection materials; a suitable amount of the first adhesive 3 is sufficient to achieve a tight connection with the second adhesive 4. The effective connection between the first adhesive 3 and the second adhesive 4 ensures the effective connection of the body panel, and the more robust panel connection prevents water leakage into the vehicle interior, thereby reducing the risk of water leakage from the body panel and improving the vehicle's sealing performance.

[0069] In one specific embodiment, reference is made to... Figure 4 and Figure 5 As shown, the sheet metal part also includes a crossbeam 2, which is used to install other parts of the vehicle and can also improve the structural strength of the vehicle body.

[0070] The first adhesive 3 is continuously arranged along the extension direction of the flange 11, so that the two sheet metal parts to be connected can be connected by the continuous first adhesive 3, thereby improving the connection reliability and sealing reliability. At the same time, the second adhesive 4 is also continuously arranged along the extension direction of the flange 11, but due to the obstruction of the crossbeam 2, the second adhesive 4 is interrupted at the position of the crossbeam, that is, the second adhesive 4 is a multi-segment structure, thereby avoiding the crossbeam 2 and improving the structural strength of the vehicle body.

[0071] In one specific embodiment, notches 111 are symmetrically provided on both sides of the crossbeam 2.

[0072] Because the second adhesive 4 breaks at the position of the crossbeam 2, its sealing performance is easily reduced. Therefore, in this embodiment, symmetrically distributed notches 111 are provided on both sides of the crossbeam 2, so that the first adhesive 3 is exposed at the notches 111. Figure 5 and Figure 7 As shown, after the first adhesive 3 is exposed, it connects with the second adhesive 4 at the notch 111, ensuring that the connection between the first adhesive 3 and the second adhesive 4 forms a closed-loop structure, thereby ensuring the stability of the connection between the crossbeam 2 and the plate 1. The effective connection between the first adhesive 3 and the second adhesive 4 provides a guarantee for the effective connection of the body sheet metal parts, and the more robust sheet metal connection can prevent water from leaking into the vehicle, thereby reducing the risk of water leakage from the body sheet metal parts and improving the sealing performance of the vehicle body.

[0073] In other embodiments, the notches 111 are arranged in pairs and can be symmetrically and evenly distributed from near to far relative to both sides of the crossbeam 2, and the number of notches 111 is not limited.

[0074] In one specific embodiment, reference is made to... Figure 2 As shown, the flange 11 has multiple solder points 112, as referenced. Figure 6 As shown, there is a gap 111 between the adjacent weld points 112 closest to the position of the crossbeam 2.

[0075] In this embodiment, the weld point 112 of the flange 11 is used not only for welding the sheet metal parts of the vehicle body, but also for positioning the application position of the first adhesive 3. (See reference) Figure 7 As shown, the first adhesive 3 is applied to the solder joint 112. The first adhesive 3 is continuously applied along the distribution direction of the solder joint 112 on the flange 11. The first adhesive 3 flows outward from the center of the solder joint 112. Due to the inertia of the flowing adhesive, the first adhesive 3 can flow into the notch 111, thereby achieving contact and connection with the second adhesive 4, avoiding the situation where no first adhesive 3 flows into the notch 111.

[0076] In addition, such as Figures 5-7 As shown, the notch 111 is located between the adjacent weld points 112 closest to the position of the crossbeam 2, ensuring that the notch 111 does not impair the welding function of the weld points 112. Moreover, the notch 111 is located at the position closest to the crossbeam 2, which allows the crossbeam 2 and the plate 1 to form a closed connection loop, improving the connection strength of the sheet metal parts of the vehicle body.

[0077] In one specific embodiment, reference is made to... Figure 6 and Figure 7 As shown, the distance between the first adhesive 3 and the side wall edge of the flange 11 is L, L=D / 2, and L>H, where 16mm≤D≤18mm. Therefore, it can be deduced that the distance L between the first adhesive 3 and the side wall edge of the flange 11 satisfies 8mm≤L≤9mm. For example, L can be 8mm, 8.2mm, 8.5mm, 8.7mm, 9mm, etc.

[0078] Preferably, the value of L can be 8mm.

[0079] In addition, the distance L between the first adhesive 3 and the side wall edge of the flange 11 can be specifically understood as the distance between the application path of the first adhesive 3 and the side wall edge of the flange 11. Since the application path of the first adhesive 3 is the distribution path of the welding point 112 on the flange 11, the distance L between the first adhesive 3 and the side wall edge of the flange 11 is specifically the distance between the welding point 112 and the side wall edge of the flange 11.

[0080] In this embodiment, when the distance L between the first adhesive 3 and the side wall edge of the flange 11 is too small, the distance of the application path notch 111 of the first adhesive 3 is too close, and the first adhesive 3 is prone to overflowing in large quantities to the side wall of the flange 11 and the notch 111. On the one hand, this risks affecting other parts inside the vehicle body, and on the other hand, it occupies the application space of the second adhesive 4. The first adhesive 3 and the second adhesive 4 cannot achieve a large-scale convergence at the notch 111, reducing the connection strength between the first adhesive 3 and the second adhesive 4. Furthermore, since the application path of the first adhesive 3 is the distribution path of the welding point 112 on the flange 11, when the welding point 1 12. If the distance between the first adhesive 3 and the side wall edge of the flange 11 is too close, it will increase the material wear at the weld point 112 in the environment during use, and reduce the connection strength of the weld. When the distance L between the first adhesive 3 and the side wall edge of the flange 11 is too large, the distance of the application path gap 111 of the first adhesive 3 is too far, and the first adhesive 3 is not easy to flow into the gap 111. The first adhesive 3 and the second adhesive 4 cannot achieve a large-scale convergence at the gap 111, which reduces the connection strength between the first adhesive 3 and the second adhesive 4, or requires more first adhesive 3 to flow into the gap 111, increasing the cost of the first adhesive 3.

[0081] In this embodiment, when the distance L between the first adhesive 3 and the side wall edge of the flange 11 is 8mm≤L≤9mm, the distance between the first adhesive 3 and the welding point 112 and the side wall edge of the flange 11 is moderate. That is, the distance of the first adhesive 3 flowing to the notch 111 is moderate. Without affecting the welding effect, the first adhesive 3 can flow smoothly to the notch 111 and converge with the second adhesive 4, which is beneficial to improving the connection effect between the first adhesive 3 and the second adhesive 4, and can also reduce the material waste of the first adhesive 3.

[0082] In one specific embodiment, this application also provides a sheet metal part, such as... Figure 3 As shown, the edge of the flange 11 is provided with at least one notch 111. The notch 111 is used for the first adhesive 3 and the second adhesive 4 applied to the plate 1 to be connected at the notch 111.

[0083] In this embodiment, reference Figure 1 and Figure 3 As shown, a notch 111 is provided on the flange 11 of the plate 1. The first adhesive 3 and the second adhesive 4 can be gathered over a large area at the notch 111. That is, the volume of the first adhesive 3 and the second adhesive 4 in the notch 111 is large, so that when adjacent sheet metal parts are bonded by the first adhesive 3 and the second adhesive 4, the bonding area is large, which provides a guarantee for the effective connection of adjacent sheet metal parts. Moreover, the more robust sheet metal connection can prevent water from leaking into the vehicle, thereby reducing the risk of water leakage from the body sheet metal parts and improving the sealing performance of the body.

[0084] In addition, by setting a notch 111 on the flange 11 of the plate 1 as a glue application connection point, maintenance personnel can visually inspect the connection status of the body glue at the notch 111, reducing the difficulty of inspection during the maintenance process.

[0085] Therefore, the vehicle body formed by welding sheet metal parts according to the embodiments of this application has high reliability and sealing performance.
