Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically, to a vehicle body side panel structure and a vehicle. Background Technology

[0002] Currently, conventional vehicle body side panels are made of sheet metal, resulting in significant weight and volume. Furthermore, they require stamping using molds for production. This production method is not only time-consuming but also generates a large amount of waste. Additionally, the typically large size of sheet metal side panels necessitates large stamping dies, leading to higher mold costs. Moreover, sheet metal side panels require electrophoresis along with the entire vehicle, resulting in a limited color range for the side panels. Utility Model Content

[0003] The problem this invention addresses is how to reduce the weight and production cost of the vehicle body side panel.

[0004] To solve the above problems, this utility model provides a vehicle body side panel structure and a vehicle.

[0005] In a first aspect, the present invention provides a vehicle body side panel structure, including an outer side panel and an inner side panel. The outer side panel is a plastic panel, and the outer side panel includes a separately configured upper side panel, a lower C-pillar panel, and a sill panel. The upper side panel, the lower C-pillar panel, and the sill panel are located outside the inner side panel and are detachably connected to the inner side panel respectively.

[0006] Optionally, the side panel includes an upper side panel, a lower C-pillar panel, and a sill panel connected in sequence. The upper side panel, the lower C-pillar panel, and the sill panel are respectively disposed opposite to the upper side panel, the lower C-pillar panel, and the sill panel, and are respectively snapped into the upper side panel, the lower C-pillar panel, and the sill panel.

[0007] Optionally, the upper side panel, the lower C-pillar panel, and the sill panel are provided with respective fasteners on the side facing the inner side panel, and the upper side panel, the lower C-pillar panel, and the sill panel are respectively fastened to the inner side panel, the inner C-pillar panel, and the inner sill panel through the fasteners.

[0008] Optionally, the upper side panel, the lower C-pillar panel, and the sill panel are each provided with a mounting seat on the side facing the inner side panel, and the fastener is installed at the mounting seat.

[0009] Optionally, both ends of the side panel are bent toward the side where the inner side panel is located to form a folded edge, the folded edge extending along the length of the side panel and abutting against the inner side panel.

[0010] Optionally, the threshold panel includes a first panel and a second panel, the second panel being horizontally disposed and connected to the lower end of the first panel, and the first panel and the second panel being respectively engaged with the inner panel of the threshold.

[0011] Optionally, the upper end of the first plate is recessed along the width direction of the vehicle body towards the inner sill plate to form a recessed portion, and the recessed portion is engaged with the inner sill plate.

[0012] Optionally, the side panel includes an A-pillar upper panel, a side upper beam panel, and a C-pillar upper panel, which are sequentially separated along the length of the vehicle body. The A-pillar upper panel, the side upper beam panel, and the C-pillar upper panel are detachably connected to the inner side panel.

[0013] Optionally, the side panel upper trim includes an A-pillar upper trim, a side upper beam trim, and a C-pillar upper trim arranged sequentially along the length of the vehicle body; the side upper beam trim and the C-pillar upper trim are integrally injection molded, or the A-pillar upper trim and the side upper beam trim are integrally injection molded, or the A-pillar upper trim, the side upper beam trim, and the C-pillar upper trim are integrally injection molded.

[0014] Secondly, this utility model provides a vehicle, including the body side structure as described above.

[0015] The beneficial effects of this utility model's vehicle side panel structure and the vehicle itself are as follows: By setting a plastic side panel on the outer side of the inner side panel, the traditional sheet metal side panel can be replaced with a plastic side panel. This not only reduces the weight of the side panel, facilitating lightweight design, but also eliminates the need for electrophoresis on the side panel along with the entire vehicle, allowing for a variety of colors to be used. Furthermore, the side panel and inner side panel are detachably connected for easy assembly and disassembly. Simultaneously, by designing the side panel as a separate structure comprising an upper side panel, a lower C-pillar panel, and a door sill panel, segmented manufacturing of the side panel is possible, reducing production difficulty, increasing production efficiency, and simplifying the structure of the production molds for the side panel, thus reducing production costs. In addition, by using plastic door sill trims instead of traditional sheet metal door sill panels (i.e., the door sill area of ​​the sheet metal side panel), when the vehicle is damaged or scratched in a collision, the door sill trims can be replaced for repairs, without having to replace the entire side panel or perform sheet metal repainting, thus saving a significant amount of after-sales maintenance costs.

[0029] In related technologies, conventional vehicle body side panels are sheet metal parts, which are heavy and bulky, and require stamping using molds for production. This production method is not only time-consuming but also generates a lot of waste. Furthermore, because sheet metal side panels are typically large, the stamping dies are also large, resulting in high mold costs. Additionally, sheet metal side panels need to be electrophoretically coated along with the entire vehicle, leading to a limited color range for the side panels.

[0030] In view of the problems existing in the above-mentioned related technologies, this utility model provides a vehicle body side panel structure and a vehicle.

[0031] Combination Figure 1 As shown, the present invention provides a vehicle body side panel structure, including an outer side panel 1 and an inner side panel 2. The outer side panel 1 is a plastic panel and includes a separate upper side panel 11, a lower C-pillar panel 12, and a door sill panel 13. The upper side panel 11, the lower C-pillar panel 12, and the door sill panel 13 are located on the outside of the inner side panel 2 and are detachably connected to the inner side panel 2.

[0032] Specifically, the vehicle side structure is mainly composed of a plastic side outer panel 1 and a sheet metal side inner panel 2. The side outer panel 1 is detachably installed on the outside of the side inner panel 2 (i.e., the side of the side inner panel 2 facing outwards). In other words, in this embodiment, the vehicle side structure uses a plastic side outer panel 1 to replace the sheet metal side outer panel of traditional vehicles.

[0033] More specifically, the side panel 1 is a split structure, mainly consisting of three parts: the upper side panel 11, the lower C-pillar panel 12, and the door sill panel 13; among them, the upper side panel 11 is typically a long strip structure, roughly along the front-rear direction of the vehicle (i.e., Figure 1 The side panel extends along the X-axis, and the upper side trim 11 is located above the door frame (i.e., Figure 1 (Z-axis positive direction); the lower C-pillar trim 12 is typically a large-area plate-like structure, located below the upper side panel trim 11, and also located behind the rear door frame (i.e. Figure 1 (X-axis reverse); the door sill trim 13 is typically a long strip extending along the front-rear direction of the vehicle and located below the C-pillar lower trim 12 and the door frame (i.e. Figure 1(Z-axis reverse). Furthermore, the upper side panel 11, the lower C-pillar panel 12, and the sill panel 13 are typically not connected to each other, but rather form small gaps at their ends, for example... Figure 1 As shown, the rear end of the upper side panel 11 does not overlap with the upper end of the lower C-pillar panel 12, and the lower end of the lower C-pillar panel 12 does not overlap with the rear end of the sill panel 13, but rather has a small gap. Furthermore, the detachable connection methods between the upper side panel 11 and the inner side panel 2, between the lower C-pillar panel 12 and the inner side panel 2, and between the sill panel 13 and the inner side panel 2 can be bolted connections or snap-fit ​​connections, etc., and are not specifically limited here.

[0034] In this embodiment, the vehicle body side panel structure can be achieved by setting a plastic side panel 1 on the outside of the inner side panel 2, replacing the sheet metal side panel of traditional vehicles. This not only reduces the weight of the side panel, facilitating lightweight design, but also eliminates the need for electrophoresis on the side panel 1 along with the entire vehicle, allowing for color diversification by assembling different colored side panel 1s. Furthermore, the side panel 1 and the inner side panel 2 are detachably connected for easy assembly and disassembly. Additionally, by setting the side panel 1 as a split structure comprising the upper side panel 11, the lower C-pillar panel 12, and the sill panel 13, segmented manufacturing of the side panel 1 is facilitated, reducing production difficulty and increasing production efficiency. Moreover, the structure of the production mold for the side panel 1 is simplified, reducing production costs. In addition, by using a plastic door sill trim 13 instead of the traditional sheet metal door sill outer panel (i.e., the door sill part of the sheet metal side panel), when the vehicle is damaged or scratched in a collision at the door sill trim 13, the door sill trim 13 can be replaced for repair, without replacing the entire side panel or performing sheet metal repainting, thus saving a significant amount of after-sales maintenance costs.

[0035] Optionally, combined Figure 1 and Figure 3 As shown, the side panel 2 includes an upper side panel 21, a lower C-pillar panel 22, and a sill panel 23 connected in sequence. The upper side panel 11, the lower C-pillar panel 12, and the sill panel 13 are respectively arranged opposite to the upper side panel 21, the lower C-pillar panel 22, and the sill panel 23, and are respectively snapped into place with the upper side panel 21, the lower C-pillar panel 22, and the sill panel 23.

[0036] In this way, the side panel 11, the C-pillar lower panel 12, and the sill panel 13 are respectively snapped onto the side panel 21, the C-pillar lower inner panel 22, and the sill inner panel 23. The snap-fit ​​method is used to achieve a detachable connection between the side panel 1 and the side panel 2, which is not only convenient to install and remove, but also secure and efficient.

[0037] Optionally, combined Figure 4 and Figure 5 As shown, the upper side panel 11, the lower C-pillar panel 12, and the sill panel 13 are each provided with a fastener 3 on the side facing the inner side panel 2. The upper side panel 11, the lower C-pillar panel 12, and the sill panel 13 are respectively fastened to the inner side panel 21, the inner C-pillar panel 22, and the inner sill panel 23 via the fastener 3. In this way, the fastening between the upper side panel 11 and the inner side panel 21, between the lower C-pillar panel 12 and the inner side panel 21, and between the sill panel 13 and the inner side panel 21 are achieved.

[0038] Optionally, combined Figure 4 , Figure 5 and Figure 6 As shown, mounting bases 114 are provided on the side of the upper side panel 11, the lower C-pillar panel 12, and the sill panel 13 facing the inner side panel 2, and fasteners 3 are installed at the mounting bases 114. In this way, the mounting bases 114 provide a mounting position for the fasteners 3, enabling connection between the fasteners 3 and the upper side panel 11. Furthermore, the fasteners 3 do not need to be integrated into the outer side panel 1; instead, they serve as separate connectors to connect the outer side panel 1 and the inner side panel 2, facilitating replacement if the fasteners 3 are damaged. In addition, since the side panel 11 and the sill panel 13 are long strips and the C-pillar lower panel 12 is a large-area panel structure, the inner side of the side panel 11, the C-pillar lower panel 12 and the sill panel 13 (that is, the side of the side panel 11, the C-pillar lower panel 12 and the sill panel 13 facing the inner side panel 21) is usually provided with multiple mounting seats 114, so that the side panel 11, the C-pillar lower panel 12 and the sill panel 13 are all connected to the inner side panel 21 by multiple fasteners 3 to form multiple snap-fit ​​fixing points, ensuring that the connection between the outer side panel 1 and the inner side panel 2 is more secure.

[0039] Furthermore, the clip 3 is usually a plastic clip, which is not only inexpensive but also readily available from the market.

[0040] Optionally, combined Figure 4 and Figure 5 As shown, the two ends of the side panel 11 are bent toward the side where the inner panel 21 is located to form a folded edge 115. The folded edge 115 extends along the length of the side panel 11 and abuts against the inner panel 21.

[0041] In this optional embodiment, the folded edge 115 is located on the inner side of the upper side panel 11 and extends along the length of the upper side panel 11. That is, the folded edge 115 is located at both ends of the upper side panel 11 along its width direction. Moreover, the upper side panel 11 is generally a long, curved plate structure, so the folded edge 115 is also generally a long, curved plate structure. Since the upper side panel 11 and the inner side panel 21 are not usually tightly fitted together, but form a cavity with vertical continuity, and the upper side panel 11 is usually located above the window frame, the upper and lower openings of the cavity between the upper side panel 11 and the inner side panel 21 are exposed to the external environment of the vehicle body without any cover, making it easy for things such as rainwater or dust to enter the cavity. Moreover, the upper and lower openings of the cavity are located at both ends of the upper side panel 11 along its width direction. Based on this, in this optional embodiment, the two ends of the side panel 11 in the width direction are bent towards the inside of the side panel 11 to form folded edges 115. Since the inner side panel 21 is located inside the side panel 11, the inner side of the side panel 11 is also the side where the inner side panel 21 is located. Moreover, the folded edges 115 abut against the inner side panel 21. In this way, by providing folded edges 115 at both ends of the side panel 11 in the width direction, the rigidity of the side panel 11 is improved. At the same time, by abutting against the inner side panel 21, the folded edges 115 can seal the cavity between the side panel 11 and the inner side panel 21, preventing dust or rainwater from entering the cavity between the side panel 11 and the inner side panel 21, thereby reducing the probability of dirt accumulating or corrosion on the sheet metal inner side panel 2.

[0042] The lower C-pillar trim 12 is usually located in the middle and rear of the vehicle body, and the sill trim 13 is usually located at the bottom of the vehicle body. The upper end of the cavity between the lower C-pillar trim 12 and the lower C-pillar inner panel 22 is covered by the side panel trim 11, and the lower end faces the ground. The upper end of the cavity between the sill trim 13 and the sill inner panel 23 is covered by the door 400, and the lower end faces the ground. Therefore, the upper and lower ends of the lower C-pillar trim 12 and the sill trim 13 do not need to be provided with a folded edge structure.

[0043] Optionally, combined Figure 7 As shown, the threshold panel 13 includes a first panel 131 and a second panel 132. The second panel 132 is horizontally arranged and connected to the lower end of the first panel 131. The first panel 131 and the second panel 132 are respectively engaged with the inner threshold panel 23.

[0044] In this optional embodiment, the first plate 131 of the sill trim 13 is typically slightly inclined relative to the Z-axis direction, making it nearly vertical, or approximately vertical. The second plate 132 of the sill trim 13 is horizontally positioned, meaning it is parallel to or slightly inclined relative to the horizontal plane. Therefore, the first plate 131 constitutes the vertical portion of the sill trim 13, and the second plate 132 constitutes the horizontal portion. In other words, the sill trim 13 has an overall bent plate structure. This configuration gives the sill trim 13 high rigidity, thereby reducing the probability of damage. Correspondingly, the inner sill plate 23 also has a bent plate structure with both vertical and horizontal portions. Figure 7 As shown, the inner sides of the first plate 131 and the second plate 132 are respectively provided with fasteners 3. The center line of the fastener 3 on the inner side of the first plate 131 is usually set along the Y-axis, and the center line of the fastener 3 on the inner side of the second plate 132 is usually set along the Z-axis. The first plate 131 is engaged with the vertical portion of the inner sill plate 23 by the fasteners 3, and the second plate 132 is engaged with the horizontal portion of the inner sill plate 23 by the fasteners 3. In this way, the engagement between the first plate 131 and the inner sill plate 23, and between the second plate 132 and the inner sill plate 23, is achieved. Moreover, by engaging both the first plate 131 and the second plate 132 of the sill trim 13 with the inner sill plate 23, the stability of the connection between the sill trim 13 and the inner sill plate 23 can be improved.

[0045] Optionally, combined Figure 7 As shown, the upper end of the first plate 131 is recessed along the width direction of the vehicle body towards the inner door sill plate 23 to form a recessed portion 1311, which is engaged with the inner door sill plate 23.

[0046] In this optional embodiment, the recess 1311 can not only avoid the lower end of the door 400 and prevent the door sill trim 13 from interfering with the door 400, but also block rainwater from entering the vehicle from the lower end of the door 400 when the door 400 is closed, thereby playing a certain sealing role. It can also reduce the distance between the first plate 131 and the inner door sill panel 23, so that the recess 1311 can be engaged with the inner door sill panel 23 by the fastener 3 to achieve the engagement between the first plate 131 and the inner door sill panel 23.

[0047] Optionally, combined Figure 2 As shown, the side panel 11 includes an A-pillar upper panel 111, a side upper beam panel 112, and a C-pillar upper panel 113, which are sequentially arranged along the length of the vehicle body. The A-pillar upper panel 111, the side upper beam panel 112, and the C-pillar upper panel 113 are detachably connected to the side inner panel 2.

[0048] It should be noted that the length direction of the vehicle body refers to... Figure 1 The X-axis direction is also the vehicle's front-to-back direction, hence it can be simply referred to as the front-to-back direction. Similarly, the vehicle width direction is the vehicle's left-to-right direction, hence it can be simply referred to as the left-to-right direction. The vehicle height direction refers to... Figure 1 The Z-axis direction is also the vertical direction of the vehicle, so it can be simply referred to as the vertical direction.

[0049] In this optional embodiment, the side panel 11 is a split structure, which includes an A-pillar upper panel 111, a side upper beam panel 112, and a C-pillar upper panel 113 arranged sequentially from the front to the rear of the vehicle. The A-pillar upper panel 111, the side upper beam panel 112, and the C-pillar upper panel 113 are not connected to each other and have a gap at their ends. The upper inner panel 21 of the side wall includes an upper inner panel 211 of the A-pillar, an upper inner panel 212 of the side wall upper beam, and an upper inner panel 213 of the C-pillar connected end to end in sequence. The upper trim panel 111 of the A-pillar is arranged opposite to the upper inner panel 211 of the A-pillar and is fastened to the upper inner panel 211 of the A-pillar by a fastener 3. The upper trim panel 112 of the side wall is arranged opposite to the upper inner panel 212 of the side wall upper beam and is fastened to the upper inner panel 212 of the side wall upper beam by a fastener 3. The upper trim panel 113 of the C-pillar is arranged opposite to the upper inner panel 213 of the C-pillar and is fastened to the upper inner panel 213 of the C-pillar by a fastener 3. Furthermore, the front end of the side upper beam trim 112 extends to the rear end of the A-pillar upper panel trim 111, and the rear end of the side upper beam trim 112 extends to the front end of the C-pillar upper panel trim 113. The front end of the A-pillar upper panel trim 111 typically extends to the upper end of the A-pillar lower inner panel 24, and the rear end of the C-pillar upper panel trim 113 typically extends to the upper end of the C-pillar lower inner panel 22. This ensures that the A-pillar upper panel trim 111, the side upper beam trim 112, and the C-pillar upper panel trim 113 are not connected to each other, but form small gaps at the ends. This ensures the overall continuity of the side upper panel trim 11, reduces the wind resistance of the side upper panel trim 11 at the segment, and also increases the coverage area of ​​the side upper panel trim 11 on the side upper inner panel 21, improving the appearance of the vehicle side.

[0050] In this way, by designing the side upper trim panel 11 as a split structure including the A-pillar upper trim panel 111, the side upper beam trim panel 112, and the C-pillar upper trim panel 113, it is easier to manufacture the side upper trim panel 11 in sections, thereby reducing the manufacturing difficulty of the side upper trim panel 11 and improving production efficiency.

[0051] Optionally, the side panel 11 includes an A-pillar upper panel 111, a side upper beam panel 112, and a C-pillar upper panel 113 arranged sequentially along the length of the vehicle body; the side upper beam panel 112 and the C-pillar upper panel 113 are integrally injection molded, or the A-pillar upper panel 111 and the side upper beam panel 112 are integrally injection molded, or the A-pillar upper panel 111, the side upper beam panel 112, and the C-pillar upper panel 113 are integrally injection molded.

[0052] In this optional embodiment, when the side upper beam trim panel 112 and the C-pillar upper panel trim panel 113 are integrally injection molded, or when the A-pillar upper panel trim panel 111 and the side upper beam trim panel 112 are integrally injection molded, the number of segments in the side upper trim panel 11 is reduced from three to two; when the A-pillar upper panel trim panel 111, the side upper beam trim panel 112, and the C-pillar upper panel trim panel 113 are integrally injection molded, the side upper trim panel 11 is a one-piece structure. For example, Figure 1 The document provides an example of the side upper beam trim panel 112 and the C-pillar upper panel trim panel 113 being integrally injection molded. This reduces the number of segments in the side upper trim panel 11 from three to two, or makes the side upper trim panel 11 a one-piece structure, thereby reducing the number of parts in the side upper trim panel 11 and even the side outer trim panel 1. This facilitates material management and improves the assembly efficiency of the vehicle body side structure.

[0053] This utility model provides a vehicle including the body side panel structure as described above.

[0054] The beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the vehicle body side panel structure described above, and will not be repeated here.

[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
