Side wall rear connecting structure and vehicle

Abstract

This application provides a rear side panel connection structure and vehicle, belonging to the field of vehicle body structure technology. It includes a side panel outer plate and a side panel drainage channel. By bending the side panel flange of the outer plate inwards towards the side panel body and connecting the flange to the drainage channel body in the front-rear direction, and connecting the drainage channel flange to the side panel body in the inward-outward direction, a combined welding method in both the inward-outward and front-rear directions is adopted. This completely avoids the traditional undercut structure design where the side panel outer plate needs to be bent in the opposite direction to form the welded flange. This greatly reduces the forming difficulty of the side panel outer plate, simplifies the stamping process, reduces breakage caused by flange angle issues, and effectively improves product yield. Because the drainage channel flange and the side panel flange are staggered in the vertical direction, mutual interference is avoided, and the stress on the side panel outer plate and the side panel drainage channel is evenly distributed.

Description

Technical Field

[0001] This application belongs to the field of vehicle body structure technology, and more specifically, relates to a side rear connection structure and a vehicle. Background Technology

[0002] In the field of automotive body manufacturing, the rear side panel connection structure is a key component ensuring the strength and stability of the entire vehicle. It is typically composed of main components such as the outer side panel, side panel drainage channels, D-pillar inner panel, and D-pillar reinforcement plate. Among them, the outer side panel provides the mounting base for the side window, while components such as the side panel drainage channels are matched and connected to the outer side panel to form the load-bearing structure of the rear side panel, which bears the lateral forces and collision impacts during vehicle movement.

[0003] Currently, the welding position between the side panel outer shell and the side water channel is located inside the water channel area. To meet welding process requirements, the side panel outer shell and the side water channel can only be welded using an undercut structure. That is, the rear side of the side panel outer shell is bent in the opposite direction of its extension to form a welding flange, which is then welded to the side water channel. However, because the welding flange angle of the side panel outer shell is close to 90 degrees, and its bending direction is opposite to the extension direction, it increases the forming difficulty of the side panel outer shell, resulting in a complex stamping process and a high risk of breakage of the outer edge of the side panel, reducing the yield rate. In addition, to reduce the chance of corrosion at the joint and increase the strength and reliability of the connection, anti-corrosion adhesive needs to be applied to the joint area after the side panel outer shell and the side water channel are welded. However, the anti-corrosion adhesive is prone to leakage, which not only affects the appearance quality of the vehicle body but may also weaken the anti-corrosion performance of the joint, shorten the service life of the vehicle body, and increase later maintenance costs and quality risks. Utility Model Content

[0004] The purpose of this application is to provide a side panel rear connection structure and vehicle, which aims to solve the problem that the existing side panel outer panel needs to be bent in the reverse to form a welded flange to connect with the side panel water channel, resulting in high processing difficulty and low yield of the side panel outer panel.

[0005] In a first aspect, embodiments of this application provide a rear side panel connection structure, including:

[0006] The side panel includes a side panel body and a side panel flange located at the rear of the side panel body, the side panel flange being bent inwards towards the side panel body; and

[0007] A side-mounted water channel is located behind the outer side panel. The side-mounted water channel includes a water channel body and a water channel flange located at the front of the water channel body. The water channel flange and the side panel flange are staggered in the vertical direction.

[0008] The side flange is connected to the main body of the water trough in the front-to-back direction, and the water trough flange is connected to the main body of the side flange in the inside-out direction.

[0009] The beneficial effect of the side panel rear connection structure provided in this application is that, compared with the prior art, by bending the side panel flange of the outer side panel inward to the inside of the side panel body and connecting the side panel flange to the main body of the water channel in the front-back direction, and connecting the water channel flange to the main body of the side panel in the inside-outside direction, the combination of welding in the inside-outside and front-back directions completely avoids the traditional undercut structure design where the outer side panel needs to be bent in the opposite direction to form the welded flange. This greatly reduces the forming difficulty of the outer side panel, simplifies the stamping process, reduces the breakage caused by flange angle issues, and effectively improves the product yield. Because the water channel flange and the side panel flange are staggered in the vertical direction, not only is mutual interference avoided, but the stress on the outer side panel and the side panel water channel is also evenly distributed.

[0010] After the side window assembly is assembled with the outer side panel, it can cover the weld points and anti-corrosion adhesive at the connection area between the outer side panel and the side drainage channel. This not only effectively prevents the anti-corrosion adhesive from leaking and affecting the vehicle's appearance, but also enhances the anti-corrosion performance of the connection point and extends the vehicle's service life. In addition, the multi-directional connection structure further optimizes the load-bearing capacity of the rear connection structure of the side panel, better bearing the lateral forces and collision impacts during vehicle operation, ensuring the overall strength and stability of the vehicle.

[0011] In conjunction with the first aspect, in one possible implementation, the rear connection structure of the side enclosure further includes a D-column reinforcing plate disposed on the inner side of the outer side enclosure panel and the side enclosure water trough, the rear part of the D-column reinforcing plate being connected to the main body of the water trough, and the front part of the D-column reinforcing plate being spaced apart from the side enclosure water trough in the inward and outward directions.

[0012] In the aforementioned technical solution, during the installation of the side window assembly, operators use a front-to-back striking method to enhance the connection's firmness. However, the side window drainage channel is highly susceptible to deformation due to the striking force. The D-pillar reinforcement plate provides a reliable support structure for the side window drainage channel. By firmly connecting to the rear of the drainage channel body, it effectively disperses the striking force during assembly, reducing the likelihood of deformation. Simultaneously, the front of the D-pillar reinforcement plate and the side window drainage channel are spaced apart in the inward and outward directions, optimizing the structural stress pattern and forming a stable mechanical support system. This resists various external forces during vehicle operation and enhances the overall rigidity of the rear connection structure of the side window.

[0013] In conjunction with the first aspect, in one possible implementation, the side-mounted water channel further includes a reinforcing flange located at the rear of the water channel body, the reinforcing flange bending inward toward the inside of the water channel body and connected to the D-column reinforcing plate in the front-rear direction.

[0014] In the above technical solution, the reinforced flange bends inward towards the main body of the water channel and forms an overlapping structure with the D-pillar reinforcing plate along the front-rear direction, completing the connection between the D-pillar reinforcing plate and the side wall water channel. This enhances the connection strength between the side wall water channel and the D-pillar reinforcing plate, effectively preventing relative displacement between components due to external forces. During vehicle movement or side window assembly, this structure can more efficiently transfer and disperse stress, reduce local stress concentration, and further optimize the stress state of the rear area of ​​the side wall. Simultaneously, the presence of the reinforced flange increases the structural rigidity of the side wall water channel itself, giving it better resistance to deformation.

[0015] In conjunction with the first aspect, in one possible implementation, the rear connection structure of the side wall further includes an inner panel of the D-pillar and a reinforcing plate. The inner panel of the D-pillar is disposed inside the reinforcing plate of the D-pillar and connected to the rear of the reinforcing plate of the D-pillar. A reinforcing cavity is formed between the front of the inner panel of the D-pillar and the reinforcing plate of the D-pillar. The reinforcing plate is disposed in the reinforcing cavity and is connected to the inner panel of the D-pillar and the reinforcing plate of the D-pillar respectively.

[0016] In the above technical solution, a reinforcement cavity is formed between the front part of the D-pillar inner panel and the D-pillar reinforcing plate. The presence of the reinforcement cavity not only improves the strength and deformation resistance of the D-pillar inner panel and the D-pillar reinforcing plate, but also efficiently disperses and transmits external forces, evenly distributing the stress acting on the side drainage channel to each component, effectively avoiding local stress concentration. The reinforcing plate tightly connects the D-pillar inner panel and the D-pillar reinforcing plate, strengthening the overall rigidity of the structure and preventing the side drainage channel from deforming into the reinforcement cavity under stress, thus improving the safety inside the driver's cab.

[0017] In conjunction with the first aspect, in one possible implementation, the reinforcing plate includes a reinforcing body and reinforcing flanges located on opposite sides of the reinforcing body. The reinforcing flanges are distributed at an angle to the reinforcing body and are connected to the inner plate of the D-pillar. The reinforcing body is connected to the reinforcing plate of the D-pillar.

[0018] In the above technical solution, the main body of the reinforcing plate is connected to the D-pillar reinforcement plate, while the reinforcing flanges on both sides are connected to the inner panel of the D-pillar, forming a "U"-shaped structure. This not only increases the contact area between the reinforcing plate and the inner panel and reinforcement plate of the D-pillar, improving the stability of the connection, but also prevents the reinforcing plate from shifting when subjected to force on one side. Simultaneously, this solution also enhances the bending and deformation resistance of the reinforcement cavity. Furthermore, when the vehicle is subjected to dynamic loads or sudden impacts, the angled structure between the reinforcing flanges and the main body can disperse stress through geometric advantages, reducing stress concentration at the connection point and allowing external forces to be evenly transmitted to the inner panel and reinforcement plate of the D-pillar, thereby improving the overall rigidity of the rear side panel connection structure.

[0019] In conjunction with the first aspect, in one possible implementation, the main body of the water trough has a reinforced area connected to the D-column reinforcing plate, the reinforced area and the reinforced body are arranged correspondingly in the front-rear direction and connected to opposite sides of the D-column reinforcing plate.

[0020] In the above technical solution, the reinforced area of ​​the main body of the water channel and the reinforced body of the reinforcing plate are correspondingly arranged in the front-rear direction and connected to the opposite sides of the D-pillar reinforcing plate. This greatly enhances the connection strength between the components, making the side wall water channel, D-pillar reinforcing plate, and reinforcing plate work closely together, effectively preventing components from loosening or separating due to external forces during vehicle operation. When under stress, the reinforced area and the reinforced body can efficiently disperse and transmit forces from different directions, optimizing the force transmission path and avoiding excessive stress concentration in local areas, thereby significantly improving the overall strength and deformation resistance of the rear connection structure of the side wall.

[0021] In conjunction with the first aspect, in one possible implementation, the side panel body has multiple first mounting areas, each of which corresponds to a second mounting area on the side panel window, for connecting the side panel body to the side panel window.

[0022] In the above technical solution, the one-to-one correspondence between the first installation area and the second installation area ensures that the connection force between the side panel body and the side window is evenly distributed, which enhances the stability and reliability of the connection. During vehicle operation, it can better resist external forces such as vibration and bumps, and prevent abnormal noises or component damage caused by loose connections.

[0023] In conjunction with the first aspect, in one possible implementation, the side panel body has a mounting boss protruding in the inward and outward directions, the mounting boss having a mounting hole forming the first mounting area.

[0024] In the above technical solution, the mounting boss increases the local rigidity of the connection between the side panel body and the side window, avoiding the problem of reduced strength in the surrounding area caused by the mounting holes in the side panel body. Furthermore, the mounting holes not only facilitate the rapid insertion of bolts, rivets, and other connectors, enabling precise positioning and a secure connection between the side panel body and the side window, but also improve assembly efficiency and reduce alignment adjustment time during installation.

[0025] In conjunction with the first aspect, in one possible implementation, at least one of the mounting holes is a strip-shaped or arc-shaped hole body for adjusting assembly and / or manufacturing tolerances.

[0026] In the above technical solution, the strip-shaped or arc-shaped hole can effectively absorb the unavoidable tolerances during manufacturing and assembly, allowing the side window to be finely adjusted within a certain range. This compensates for the adaptation problems caused by factors such as component processing errors and cumulative assembly errors, and also enables pre-positioning. This embodiment not only reduces the requirements for component processing accuracy and effectively controls production costs, but also greatly simplifies the assembly process, reduces assembly difficulty, shortens assembly time, and improves production efficiency.

[0027] Secondly, embodiments of this application also provide a vehicle including the aforementioned side rear connection structure.

[0028] The beneficial effects of the vehicle provided in this application are that, compared with the prior art, it adopts the aforementioned rear side panel connection structure. By bending the side panel flange of the outer side panel inward towards the inner side panel body and connecting the side panel flange to the main body of the water channel in the front-rear direction, and connecting the water channel flange to the main body of the side panel in the inward and outward directions, the combined welding method in the inward and outward directions and the front-rear direction completely avoids the traditional undercut structure design where the outer side panel needs to be bent in the opposite direction to form the welded flange. This greatly reduces the forming difficulty of the outer side panel, simplifies the stamping process, reduces the breakage caused by flange angle issues, and effectively improves the product yield. Because the water channel flange and the side panel flange are staggered in the vertical direction, not only is mutual interference avoided, but the stress on the outer side panel and the side water channel is also evenly distributed.

[0029] After the side window assembly is assembled with the outer side panel, it can cover the weld points and anti-corrosion adhesive at the connection area between the outer side panel and the side drainage channel. This not only effectively prevents the anti-corrosion adhesive from leaking and affecting the vehicle's appearance, but also enhances the anti-corrosion performance of the connection point and extends the vehicle's service life. In addition, the multi-directional connection structure further optimizes the load-bearing capacity of the rear connection structure of the side panel, better bearing the lateral forces and collision impacts during vehicle operation, ensuring the overall strength and stability of the vehicle.

[0040] Please refer to the following: Figures 1 to 3 The following describes the rear side panel connection structure and the vehicle provided in this application. The rear side panel connection structure includes a side panel outer plate 1 and a side panel drainage channel 2. The side panel outer plate 1 includes a side panel main body 101 and a side panel flange 102 located at the rear of the side panel main body 101. The side panel flange 102 is bent inward toward the side panel main body 101. The side panel drainage channel 2 is located behind the side panel outer plate 1. The side panel drainage channel 2 includes a drainage channel main body 201 and a drainage channel flange 202 located at the front of the drainage channel main body 201. The drainage channel flange 202 and the side panel flange 102 are staggered in the vertical direction. The side panel flange 102 is connected to the drainage channel main body 201 in the front-rear direction, and the drainage channel flange 202 is connected to the side panel main body 101 in the inner-outer direction.

[0041] Compared with the prior art, the side panel rear connection structure provided in this application bends the side panel flange 102 of the outer side panel 1 inward toward the side panel body 101, and connects the side panel flange 102 to the water channel body 201 in the front-to-back direction, while the water channel flange 202 is connected to the side panel body 101 in the inside-outside direction. This combined welding method in both the inside-outside and front-to-back directions completely avoids the traditional undercut structure design where the outer side panel 1 needs to be bent in the opposite direction to form the welded flange. This greatly reduces the forming difficulty of the outer side panel 1, simplifies the stamping process, reduces breakage caused by flange angle issues, and effectively improves product yield. Because the water channel flange 202 and the side panel flange 102 are staggered in the vertical direction, mutual interference is avoided, and the force on the outer side panel 1 and the side water channel 2 is evenly distributed.

[0042] After the side window assembly is assembled with the outer side panel 1, it can cover the weld points and anti-corrosion adhesive in the connection area between the outer side panel 1 and the side water channel 2. This not only effectively avoids the problem of anti-corrosion adhesive leakage affecting the vehicle's appearance, but also enhances the anti-corrosion performance of the connection point and extends the vehicle's service life. In addition, the multi-directional connection structure further optimizes the load-bearing performance of the rear connection structure of the side panel, better bearing the lateral forces and collision impacts during vehicle operation, and ensuring the overall strength and stability of the vehicle.

[0043] Optionally, the side body 101 includes a first connecting area and a second connecting area distributed along the vertical direction, and the first connecting area and the second connecting area are distributed at an angle.

[0044] Optionally, the side flange 102 is located at the rear of the first connecting area, and the water channel flange 202 is connected to the second connecting area.

[0045] Please see Figures 1 to 3In some embodiments, the rear connection structure of the side enclosure also includes a D-pillar reinforcing plate 3 disposed inside the outer side panel 1 and the side enclosure water trough 2. The rear part of the D-pillar reinforcing plate 3 is connected to the main body 201 of the water trough, and the front part of the D-pillar reinforcing plate 3 and the side enclosure water trough 2 are distributed at intervals in the inward and outward directions.

[0046] During the installation of the side window assembly, operators need to tap the side drainage channel 2 in both front and rear directions to improve the connection's firmness. However, the side drainage channel 2 is highly susceptible to deformation due to the tapping force. The D-pillar reinforcement plate provides a reliable support structure for the side drainage channel 2. By firmly connecting to the rear of the drainage channel body 201, it effectively disperses the tapping force during assembly, reducing the likelihood of deformation of the side drainage channel 2. Simultaneously, the front of the D-pillar reinforcement plate and the side drainage channel 2 are spaced apart in both the inward and outward directions, optimizing the structural stress pattern and forming a stable mechanical support system. This system resists various external forces during vehicle operation and enhances the overall rigidity of the rear connection structure of the side window. This embodiment not only ensures the accuracy and stability of the side window assembly installation but also guarantees the structural reliability of the side drainage channel 2 area during long-term vehicle use, effectively reducing component damage and performance degradation caused by deformation and extending the vehicle's service life.

[0047] Please see Figures 1 to 2 In some embodiments, the side-mounted water channel 2 also includes a reinforcing flange 203 located at the rear of the water channel body 201. The reinforcing flange 203 bends toward the inside of the water channel body 201 and is connected to the D-pillar reinforcing plate 3 in the front-back direction.

[0048] The reinforcing flange 203 bends inward toward the main body 201 of the water channel and overlaps with the D-pillar reinforcing plate along the front-rear direction, completing the connection between the D-pillar reinforcing plate 3 and the side wall water channel 2. This enhances the connection strength between the side wall water channel 2 and the D-pillar reinforcing plate, effectively preventing relative displacement between components due to external forces. During vehicle movement or side window assembly assembly, this structure can more efficiently transfer and disperse stress, reduce local stress concentration, and further optimize the stress state of the rear area of ​​the side wall. Simultaneously, the presence of the reinforcing flange 203 increases the structural rigidity of the side wall water channel 2 itself, giving it better resistance to deformation.

[0049] Please see Figure 1 In some embodiments, the rear connection structure of the side wall also includes an inner panel 4 of the D-pillar and a reinforcing plate 5. The inner panel 4 of the D-pillar is disposed inside the reinforcing plate 3 of the D-pillar and is connected to the rear part of the reinforcing plate 3 of the D-pillar. A reinforcing cavity is formed between the front part of the inner panel 4 of the D-pillar and the reinforcing plate 3 of the D-pillar. The reinforcing plate 5 is disposed in the reinforcing cavity and is connected to the inner panel 4 of the D-pillar and the reinforcing plate 3 of the D-pillar respectively.

[0050] A reinforcement cavity is formed between the front part of the D-pillar inner panel 4 and the D-pillar reinforcing plate 3. The presence of this cavity not only enhances the strength and deformation resistance of the D-pillar inner panel 4 and the D-pillar reinforcing plate 3, but also efficiently disperses and transmits external forces, evenly distributing the stress acting on the side wall water channel 2 to each component, effectively avoiding localized stress concentration. The reinforcing plate 5 tightly connects the D-pillar inner panel and the D-pillar reinforcing plate, strengthening the overall rigidity of the structure and preventing the side wall water channel 2 from deforming into the reinforcement cavity under stress, thus improving safety within the driver's cab. The solution in this embodiment enhances the overall strength of the rear side wall connection structure, ensuring that the vehicle maintains good structural stability under complex operating conditions, reducing the risk of component damage, and extending the vehicle's service life.

[0051] Optionally, the inner panel 4 of the D-pillar includes an upper inner panel and a lower inner panel. The upper inner panel is connected to the upper part of the D-pillar reinforcing plate 3, and the lower inner panel is connected to the lower part of the D-pillar reinforcing plate 3 and is located inside the upper inner panel. To reduce the processing difficulty, the upper inner panel and the lower inner panel can be processed into separate components, and then connected by welding or bonding.

[0052] Please see Figure 3 In some embodiments, the reinforcing plate 5 includes a reinforcing body 502 and reinforcing flanges 501 located on opposite sides of the reinforcing body 502. The reinforcing flanges 501 are distributed at an angle to the reinforcing body 502 and are connected to the inner plate 4 of the D-pillar. The reinforcing body 502 is connected to the reinforcing plate 3 of the D-pillar.

[0053] The reinforcing body 502 of the reinforcing plate 5 is connected to the D-pillar reinforcing plate, while the reinforcing flanges 501 on both sides are connected to the inner D-pillar panel 4, forming a "U"-shaped structure. This not only increases the contact area between the reinforcing plate 5 and the inner D-pillar panel and the D-pillar reinforcing plate, improving the stability of the connection, but also prevents the reinforcing plate 5 from shifting when subjected to force on one side. Simultaneously, this design also enhances the bending and deformation resistance of the reinforcing cavity. Furthermore, when the vehicle is subjected to dynamic loads or sudden impacts, the angled structure between the reinforcing flanges 501 and the reinforcing body 502 can disperse stress through geometric advantages, reducing stress concentration at the connection point and allowing external forces to be evenly transmitted to the inner D-pillar panel and the D-pillar reinforcing plate, thereby improving the overall rigidity of the rear side panel connection structure.

[0054] Please see Figure 3 In some embodiments, the main body 201 of the water channel has a reinforced area 2011 connected to the D-column reinforcing plate 3. The reinforced area 2011 and the reinforced body 502 are arranged correspondingly in the front-rear direction and connected to the opposite sides of the D-column reinforcing plate 3.

[0055] The reinforced area 2011 of the main body 201 of the water channel and the reinforced body 502 of the reinforcing plate 5 are correspondingly arranged in the front-rear direction and connected to the opposite sides of the D-pillar reinforcing plate. This greatly enhances the connection strength between the components, making the side wall water channel 2, the D-pillar reinforcing plate and the reinforcing plate 5 tightly connected, effectively preventing the components from loosening or separating due to external forces during vehicle operation. When under stress, the reinforced area 2011 and the reinforced body 502 can efficiently disperse and transmit forces from different directions, optimize the force transmission path, and avoid excessive stress concentration in local areas, thereby significantly improving the overall strength and deformation resistance of the rear connection structure of the side wall. In this embodiment, the corresponding connection scheme of the reinforced area 2011, the D-pillar reinforcing plate 3 and the reinforced body 502 significantly improves the overall performance of the rear connection structure of the side wall. Whether facing complex vibrations and lateral forces during vehicle operation or the impact force during the assembly of the side window assembly, this structure can effectively limit the deformation trend of the side wall water channel 2 with its stable mechanical properties, ensuring the structural stability of the rear area of ​​the side wall.

[0056] Please see Figure 1 In some embodiments, the side panel body 101 has multiple first mounting areas, and the first mounting areas are configured one-to-one with the second mounting areas on the side panel window to realize the connection between the side panel body 101 and the side panel window.

[0057] The multiple first mounting areas on the side panel body 101 correspond one-to-one with the second mounting areas on the side window, greatly improving assembly efficiency. During installation, operators can quickly locate the components based on the correspondence, reducing installation errors and debugging time, and effectively improving production efficiency. Simultaneously, the one-to-one correspondence between the first and second mounting areas ensures a uniform distribution of connection force between the side panel body 101 and the side window, enhancing the stability and reliability of the connection. During vehicle operation, it can better resist external forces such as vibration and bumps, preventing abnormal noises or component damage caused by loose connections.

[0058] Optionally, the first mounting area and the second mounting area can be welded, snap-fitted, screwed, or glued together. For example, both the first and second mounting areas may have connection holes, and screws or snap-fit ​​fittings can be inserted into the corresponding connection holes to achieve the connection.

[0059] Please see Figure 1 In some embodiments, the side body 101 has a mounting boss protruding in the inward and outward directions, and the mounting boss has a mounting hole 1011, which forms a first mounting area.

[0060] In the above technical solution, the mounting boss increases the local rigidity of the connection between the side panel body 101 and the side window, avoiding the problem of reduced strength in the surrounding area caused by the mounting hole 1011. Furthermore, the mounting hole 1011 not only facilitates the quick insertion of bolts, rivets, and other connectors, but also enables precise positioning and stable connection between the side panel body 101 and the side window, improving assembly efficiency and reducing alignment adjustment time during installation.

[0061] Optionally, the side window has a mounting component that engages with the mounting hole 1011. The mounting component can be a threaded component or a snap-fit ​​component, thereby connecting the side window to the side body 101. Alternatively, fixing holes corresponding to the mounting hole 1011 can be provided in the side window, and threaded components or snap-fit ​​components can be inserted into the corresponding mounting hole 1011 and fixing holes to achieve connection.

[0062] Please see Figure 1 In some embodiments, at least one mounting hole 1011 is a strip-shaped or arc-shaped hole body for adjusting assembly and / or manufacturing tolerances.

[0063] Strip-shaped or arc-shaped holes can effectively absorb unavoidable tolerances during manufacturing and assembly, allowing for fine-tuning of the side window's position within a certain range. This compensates for fitting problems caused by component machining errors and cumulative assembly errors, while also enabling pre-positioning. This embodiment not only reduces the requirements for component machining accuracy and effectively controls production costs, but also greatly simplifies the assembly process, reduces assembly difficulty, shortens assembly time, and improves production efficiency.

[0064] Optionally, the side panel body 101 also has positioning holes, which can be circular or polygonal. Alternatively, one of the mounting holes 1011 can be used as the positioning hole. The positioning holes provide a stable reference point for the side panel window during assembly, ensuring the accuracy of the side panel window's installation position and avoiding component misalignment or poor fit due to installation deviations. This ensures the stability and reliability of the connection between the side panel window and the side panel body 101.

[0065] Based on the same inventive concept, this application also provides a vehicle including the aforementioned side rear connection structure.

[0066] Compared with the prior art, the rear connection structure of the side panel provided in this application adopts the aforementioned rear connection structure. By bending the side panel flange 102 of the outer side panel 1 inward toward the inner side panel body 101, and connecting the side panel flange 102 to the main body 201 of the water channel along the front-back direction, and connecting the water channel flange 202 to the main body 101 of the side panel along the inside-outside direction, the combination of welding in the inside-outside and front-back directions completely avoids the traditional undercut structure design where the outer side panel 1 needs to be bent in the opposite direction to form the welded flange. This greatly reduces the forming difficulty of the outer side panel 1, simplifies the stamping process, reduces the breakage caused by flange angle issues, and effectively improves the product yield. Since the water channel flange 202 and the side panel flange 102 are staggered in the vertical direction, not only is mutual interference avoided, but the stress on the outer side panel 1 and the side water channel 2 is also evenly distributed.

[0067] After the side window assembly is assembled with the outer side panel 1, it can cover the weld points and anti-corrosion adhesive in the connection area between the outer side panel 1 and the side water channel 2. This not only effectively avoids the problem of anti-corrosion adhesive leakage affecting the vehicle's appearance, but also enhances the anti-corrosion performance of the connection point and extends the vehicle's service life. In addition, the multi-directional connection structure further optimizes the load-bearing performance of the rear connection structure of the side panel, better bearing the lateral forces and collision impacts during vehicle operation, and ensuring the overall strength and stability of the vehicle.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
