Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a side panel structure and a vehicle having the same. Background Technology

[0002] With the diversification of energy utilization methods, there is a need to add charging and refueling ports to mule carts in the field of mule cart modification. Currently, the modification of charging and refueling ports mainly relies on traditional manufacturing processes, among which sheet metal stamping is a common method. This involves first creating a specialized stamping die according to design requirements. The sheet metal material is then stamped into the required shapes of the charging and refueling ports using stamping equipment, and finally, the formed charging and refueling ports are assembled to the side sheet metal of the mule cart.

[0003] However, sheet metal stamping technology involves extremely high costs for manufacturing stamping dies. The design, manufacturing, and debugging of dies require specialized technical personnel and substantial financial investment. For experimental or small-batch mule cart modification projects, the high cost of dies makes these projects difficult to implement. Furthermore, the process from die design to final product output is lengthy. Die design modifications, problem-solving during manufacturing, and debugging can all delay project progress, failing to meet the rapidly evolving market demands. Moreover, if design issues are discovered during the appearance verification phase, requiring die remanufacturing, this not only increases costs but also further extends the project cycle. For projects needing rapid design finalization, traditional sheet metal stamping methods are unsuitable. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is for reference. Figures 1-15 The side structure 100 according to a first aspect embodiment of the present invention is described.

[0026] like Figure 1 and Figure 2 As shown, the side panel structure 100 according to the first aspect of the present invention includes: a side panel 10 and a printing plate 20.

[0027] Specifically, the side panel 10 has an installation port 11; the printing plate 20 is a 3D printed part, which covers the installation port 11. A filling port 23 is formed on the printing plate 20, which serves as the vehicle's charging port and / or fuel filler port. For example, the filling port 23 can be used solely as the vehicle's charging port, or solely as the vehicle's fuel filler port, or simultaneously as both the vehicle's charging port and fuel filler port.

[0028] In this embodiment, the printing plate 20 with the filling port 23 is a 3D printed part. That is, the printing plate 20 with the filling port 23 can be directly printed using 3D printing technology. Therefore, the printing plate 20 with the filling port 23 can be quickly obtained through 3D printing without the need to manufacture expensive stamping molds, greatly reducing costs and shortening the cycle time. This is particularly beneficial for small-batch mule cart modification projects in the engineering and appearance design stages, where costs can be significantly reduced. Furthermore, when the appearance design of the filling port 23 needs to be modified, only the 3D printing data of the printing plate 20 needs to be modified, and it needs to be reprinted; there is no need to remake the mold, making it convenient and quick.

[0029] According to the side panel structure 100 of this utility model embodiment, a printing plate 20 with a filling port 23 is formed by 3D printing, and the printing plate 20 is installed at the mounting port 11 of the side panel 10. This can reduce costs, shorten the cycle, and improve work efficiency. It solves the problems of high development costs and long cycles in the engineering and styling verification stages of the traditional sheet metal stamping forming method in the process of modifying the charging and refueling ports of mule carts. It is suitable for small-batch and diversified mule cart modification needs.

[0030] In some embodiments of this invention, the printing plate 20 is configured to be printed from nylon powder using a selective laser sintering (SLS) process. SLS is an additive manufacturing process that uses powders such as nylon and metal as raw materials. A computer-controlled laser beam selectively irradiates and sintersects powder particles along a 3D model slicing path, causing them to melt and bond together to form the desired shape. During the forming process, unsintered powder can act as a support, eliminating the need for additional support structures and enabling the integrated manufacturing of parts with complex geometries.

[0031] In this embodiment, after nylon powder is sintered by selective laser sintering, it can form a printed part with good impact resistance, wear resistance and good toughness, thereby improving the structural strength of the printed part and its ability to withstand loads and environmental stresses, so that the printing plate 20 can meet the strength requirements of the side structure 100.

[0032] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, one side surface of the printing plate 20 is a first surface 21, and a recessed groove 24 is formed on the first surface 21. The groove 24 is arranged around the periphery of the printing plate 20 and extends in a ring shape along the circumference of the printing plate 20. The groove 24 is open on one side facing the edge of the printing plate 20, and the periphery of the mounting port 11 fits into the groove 24.

[0033] Specifically, such as Figure 2 and Figure 4As shown, in the left-right direction of the vehicle, the surface of the printing plate 20 facing outwards from the vehicle body is the first surface 21. The edge area of ​​the first surface 21 is recessed into the other surface (second surface 22) of the printing plate 20 to form a groove 24. The groove 24 is annular. During the assembly of the printing plate 20 and the side panel 10, the periphery of the mounting opening 11 of the side panel 10 fits into the groove 24, and the periphery of the mounting opening 11 facing outwards from the vehicle body is flush with the first surface 21. Thus, the appearance of the side panel structure 100 is neat and aesthetically pleasing.

[0034] In other words, such as Figure 4 As shown, the printing plate 20 includes a plate body and a flange edge 28. The plate body is an annular frame structure with a filling port 23 defined on its inner side. The flange edge 28 is connected to the outer periphery of the plate body and extends in an annular shape along the circumference of the plate body. The outer surface of the plate body facing the vehicle body is formed as a first surface 21, and the outer surface of the flange edge 28 is located on the inner side of the first surface 21 facing the vehicle body. At this time, the flange edge 28 and the plate body cooperate to form a groove 24. During the assembly of the printing plate 20 and the side panel 10, the plate body is located radially inner to the mounting port 11, and the flange edge 28 and the periphery of the mounting port 11 are stacked in the thickness direction of the side panel 10. Thus, an overlapping connection between the printing plate 20 and the side panel 10 can be achieved, improving the structural strength and connection reliability of the connection position between the printing plate 20 and the side panel 10.

[0035] In some examples, the depth of the groove 24 in the thickness direction of the side panel 10 is approximately equal to the thickness of the side panel 10; specifically, the depth of the groove 24 is slightly greater than the thickness of the side panel 10. This facilitates achieving a flush arrangement between the outer surface of the side panel 10 and the first surface 21 of the printed part.

[0036] In some embodiments of this utility model, such as Figure 4 As shown, the minimum width of the groove 24 in the direction from the center of the filling port 23 toward the periphery of the printing plate 20 can be 10mm-15mm. For example, the minimum width of the groove 24 can be 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. This increases the overlap length and overlap area between the printing plate 20 and the side panel 10, thereby improving the reliability of the connection between the printing plate 20 and the side panel 10.

[0037] For example Figure 4 As shown, the printing plate 20 is a rectangular plate, and the groove 24 extends in a rectangular shape along the circumference of the printing plate 20. The width of the groove 24 is the distance between the side wall of the groove 24 facing the filling port 23 and the edge of the printing plate 20 on the same side in the length or width direction of the printing plate 20, and the width of the groove 24 is greater than or equal to 10 mm and less than or equal to 15 mm.

[0038] In some embodiments of this utility model, the printing plate 20 and the side panel 10 are bonded together with structural adhesive. Furthermore, the inner wall of the groove 24 and the edge of the mounting opening 11 are bonded together with structural adhesive. This improves the assembly efficiency of the printing plate 20 and the side panel 10 while ensuring the structural strength of the connection between them. The depth of the groove 24 is equal to the thickness of the side panel 10 plus the thickness of the structural adhesive. Additionally, compared to connections using fasteners or snap-fit ​​connections, this embodiment, by bonding the printing plate 20 to the side panel 10, reduces the number of parts, improves assembly efficiency, and lowers processing difficulty.

[0039] In some embodiments of this utility model, such as Figure 4 As shown, raised ribs 25 are formed on the bottom wall of the groove 24. The raised ribs 25 can be convex, elongated, straight, curved, or annular. By providing raised ribs 25 on the bottom wall of the groove 24, the structural strength of the printing plate 20 in the groove 24 area (flange edge 28) is enhanced. Furthermore, the raised ribs 25, by abutting against the periphery of the mounting opening 11, ensure a uniform thickness of the structural adhesive layer within the groove 24. This improves the consistency and flatness of the bonding between the printing plate 20 and the side panel 10, increases bonding efficiency and reliability, and enhances the uniformity of stress on the structural adhesive around the printing plate 20.

[0040] In some embodiments of this utility model, such as Figure 4 and Figure 9 As shown, there are multiple ribs 25, which are arranged at intervals along the circumference of the printing plate 20. For example, the number of ribs 25 can be two, three, five, eight, ten, fifteen, or twenty or more. The ribs 25 can extend in a straight line, and one end of the rib 25 is connected to the side wall of the groove 24 facing the filling port 23, while the other end of the rib 25 extends to be flush with the edge of the printing plate 20. This improves the uniformity of the strength of the area where the groove 24 is located in the circumferential direction of the printing plate 20, and also improves the uniformity of the distribution of the structural adhesive layer in the circumferential direction of the printing plate 20.

[0041] In some embodiments of this utility model, such as Figure 4 and Figure 9As shown, the height of the rib 25 protruding from the bottom wall of the groove 24 can be 0.2mm-0.3mm. For example, the height of the rib 25 protruding from the bottom wall of the groove 24 can be 0.2mm, 0.22mm, 0.24mm, 0.25mm, 0.26mm, 0.28mm, or 0.3mm. This allows the structural adhesive layer coated within the groove 24 to have sufficient thickness, ensuring the adhesion between the printing plate 20 and the side panel 10 while avoiding an excessively thick structural adhesive layer, thus reducing costs.

[0042] In some embodiments of this utility model, such as Figure 9 As shown, the printing plate 20 has multiple through holes 26 formed around its periphery. These through holes 26 penetrate the bottom wall of the groove 24 and are spaced apart along the circumference of the printing plate 20. The through holes 26 are filled with structural adhesive. For example, the number of through holes 26 can be two, three, four, five, six, eight, ten, fifteen, or twenty or more. When the printing plate 20 is assembled with the side panel 10, the structural adhesive is filled not only between the printing plate 20 and the side panel 10 but also within the through holes 26. This increases the contact area between the structural adhesive and the printing plate 20, and the cured structural adhesive within the through holes 26 forms an anchoring structure, further enhancing the adhesion between the printing plate 20 and the side panel 10 and improving the connection strength.

[0043] For example Figure 9 and Figure 10 As shown, a plurality of ribs 25 are formed in the groove 24. The plurality of ribs 25 extend radially along the filling port 23 and are spaced apart in the circumferential direction of the filling port 23. In the circumferential direction of the filling port 23, at least one through hole 26 is provided between two adjacent ribs 25. That is, there may be one, two, three, four or five or more through holes 26 between two adjacent ribs 25. In this way, if the area between two adjacent ribs 25 is defined as an adhesive area, structural adhesive will form an anchoring structure in the through hole 26 in each adhesive area, thereby improving the adhesive effect of each adhesive area.

[0044] In some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the other side surface of the printing plate 20 is the second surface 22. The cross-sectional size of the through-hole 26 gradually increases in the direction from the first surface 21 towards the second surface 22. This increases the amount of structural adhesive filling the through-hole 26 and the bonding contact area between the structural adhesive and the inner wall of the through-hole 26, enhancing the bonding stability and reliability between the printing plate 20 and the side panel 10. It also allows for greater stress dispersion at the bonding points of the structural adhesive on the inner wall of the through-hole 26, reducing local stress concentration between the structural adhesive and the inner wall of the through-hole 26, preventing cracking between the structural adhesive and the inner wall of the through-hole 26, and improving bonding reliability.

[0045] In some embodiments of this utility model, such as Figure 11 and Figure 12 As shown, a protrusion 27 is formed on the inner wall of the through hole 26. The protrusion 27 can be in the shape of a convex hull, or it can extend into an elongated shape. The protrusion 27 can extend along a straight line, a curve, or even a ring. The number of protrusions 27 can be one or more, for example, one, two, three, five, eight, ten, twenty, or more.

[0046] In this embodiment, a protrusion 27 is formed on the inner wall of the through hole 26. The protrusion 27 can form an interlocking structure with the structural adhesive filled in the through hole 26, which greatly improves the structural force between the structural adhesive and the inner wall of the through hole 26 and prevents the structural adhesive from falling off the inner wall of the through hole 26. At the same time, the protrusion 27 can break the smooth interface of the inner wall of the through hole 26, so that the stress is dispersed at the contact position between the structural adhesive layer and the protrusion 27, reducing local stress concentration and reducing the risk of cracking of the structural adhesive layer. Thus, the bonding reliability between the printing plate 20 and the side panel 10 can be further improved, and the impact resistance of the side structure 100 can be improved.

[0047] In some embodiments of this utility model, such as Figure 11 and Figure 12 As shown, in the direction from the first surface 21 to the second surface 22, the height of the protrusion 27 protruding from the inner wall of the through hole 26 gradually increases, and / or, in the direction from the first surface 21 to the second surface 22, the width of the protrusion 27 in the circumferential direction of the through hole 26 gradually increases. The gradual increase in both the protrusion height and / or width of the protrusion 27 allows it to take on a conical shape, and the structural adhesive embedded between the protrusions 27 is formed into an inverted conical structure. Therefore, in the direction from the first surface 21 to the second surface 22, the interlocking force between the structural adhesive and the protrusion 27 gradually increases, thereby further improving the bonding strength between the printing plate 20 and the side panel 10, and further reducing the risk of the structural adhesive layer detaching.

[0048] In some embodiments of this utility model, such as Figure 5 and Figure 13 As shown, the mounting port 11 is rectangular, as... Figure 4 and Figure 9 As shown, the outer contour of the printing plate 20 is rectangular. This simplifies the structure of the mounting port 11 and the printing plate 20, reducing processing difficulty and cost.

[0049] In some embodiments of this utility model, the thickness of the printing plate 20 is 2mm-5mm. For example, the thickness of the printing plate 20 can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, etc. This ensures the structural strength of the printing plate 20 and improves the structural strength and service life of the side structure 100.

[0050] The vehicle according to a second aspect embodiment of the present invention includes a side panel structure 100 according to the first aspect embodiment of the present invention described above. The vehicle in this embodiment can be a prototype vehicle during the development phase.

[0051] According to the vehicle of this utility model embodiment, by setting the side structure 100 of the first aspect embodiment above, the side structure 100 is formed by 3D printing a printing plate 20 with a filling port 23, and the printing plate 20 is installed at the mounting port 11 position of the side panel 10, which can reduce costs, shorten the cycle, and improve work efficiency. It solves the problem of high development costs and long cycles in the engineering and styling verification stages of the traditional sheet metal stamping forming method in the process of modifying the charging and refueling ports of mule cars, and is suitable for small-batch and diversified mule car modification needs.

[0052] The following will refer to Figures 1-15 The side structure 100 according to two specific embodiments of the present invention is described.

[0053] Example 1, as Figures 1-5 As shown, the side panel structure 100 includes a side panel 10 and a 3D-printed plate 20. The side panel 10 has a thickness of 0.65 mm, and the plate 20 has a thickness of 3 mm. Specifically, a rectangular mounting opening 11 is formed on the side panel 10. The outer contour of the plate 20 is rectangular. The edge of the plate 20 overlaps and is bonded to the side panel 10 in the thickness direction. Ribs 25 are formed at the bonding positions of the plate 20 and the side panel 10. There are multiple ribs 25, which are spaced apart along the circumference of the plate 20. The plate 20 is annular in shape, and an inlet 23 is defined on its inner side.

[0054] The following describes the processing method of the side structure 100 in this embodiment.

[0055] Step 1: Perform structural parameter modeling on the printing plate 20.

[0056] Specifically, the three-dimensional data of the printing plate 20 is input, and the thickness of the printing plate 20 is set to 3mm to ensure the structural strength of the 3D print and meet the strength requirements of the modification. Figure 4 As shown.

[0057] The outer contour of the printing plate 20 is set to a rectangular shape. Taking the outer surface (first surface 21) of the printing plate 20 as the reference surface, the printing plate 20 is recessed by 0.65mm along the thickness direction at the edge position, so that the edge area of ​​the printing plate 20 is designed as a flange edge 28 with a width of 10mm. This allows the flange edge 28 to overlap with the side panel 10. The reference surface area can be made into an embedded structure, embedded in the mounting opening 11 of the side panel 10, to ensure the assembly flatness between the reference surface and the outer surface of the side panel 10. At the same time, the outer surface of the flange edge 28 serves as the adhesive surface with the side panel 10. Rectangular ribs 25 are evenly distributed in an array at 40mm intervals on the adhesive surface. The protrusion 27 of the ribs 25 has a height of 0.2mm. The ribs 25 are used to ensure the uniform thickness of the structural adhesive layer during bonding, ensuring the bonding flatness between the side panel 10 and the printing plate 20, reducing the subsequent sanding and finishing time, and improving work efficiency. Figure 4 As shown.

[0058] Step 2: Digitally position and cut the side panel 10.

[0059] Specifically, such as Figure 5 As shown, a coordinate measuring machine is used to mark four coordinate positioning points on the side panel 10 to generate a rectangular cutting path. After cutting along the cutting path, the mounting opening 11 can be formed. The cutting size of the mounting opening 11 is equal to the inner edge size of the flange edge 28 plus 0.2mm of assembly clearance.

[0060] A cutting tool is used to precisely drill holes along the cutting line to form the installation opening 11, and protective treatment is applied to the cut.

[0061] Step 3: 3D print the printing plate 20 and assemble and connect the printing plate 20 with the side panel 10.

[0062] Specifically, the SLS laser nylon powder sintering process is used to quickly print the printing plate 20. Structural adhesive is applied to the outer surface of the flange edge 28 of the printing plate 20, with the adhesive thickness controlled at 0.2mm~0.3mm. The printing plate 20 is then aligned and assembled with the side panel 10, such as... Figure 2 As shown; multiple magnetic components 3 are arranged on both the inner and outer sides of the side structure 100. The magnetic components 3 can be neodymium iron boron magnets. The multiple magnetic components 3 are arranged at intervals in the circumferential direction of the printing plate 20 and are arranged in groups opposite each other in the thickness direction of the side structure 100. For example, the multiple magnetic components 3 are arranged in an array with an 80mm spacing, and clamp the printing plate 20 and the side plate 10 on the inner and outer sides of the side structure 100 by magnetic attraction. Figure 3 As shown; let stand for 6 hours until the structural adhesive is fully cured.

[0063] The side structure 100 of this embodiment introduces 3D printing technology to form the printed plate 20, which changes the traditional method of relying on sheet metal stamping. The required printed plate 20 with filling port 23 can be obtained quickly through 3D printing, without the need to make expensive stamping molds, which greatly reduces costs and shortens the cycle.

[0064] The side structure 100 of this embodiment is suitable for prototype vehicles in the styling verification stage and other short-term verification projects.

[0065] The side panel structure 100 in this embodiment can shorten the single modification cycle from 30 days in the traditional method to 3 days, reducing the time by 90%, and reducing the cost of traditional sheet metal stamping molds from 100,000 yuan to 1,000 yuan, improving cost-effectiveness by 100 times. It significantly shortens the modification cycle, reduces costs, meets the high-efficiency adaptation requirements of the prototype vehicle testing stage, and is particularly suitable for rapid iteration in the styling verification stage.

[0066] Example 2, as Figures 6-15 As shown, the structure of this embodiment is roughly the same as that of embodiment one, with the same reference numerals used for the same components. The only difference is that: in this embodiment two, a through hole 26 is formed on the flange edge 28. The through hole 26 is a circular hole, and a plurality of protrusions 27 are arranged at intervals in the circumferential direction of the through hole 26 on the inner wall of the through hole 26. In the direction from the first surface 21 of the printing plate 20 to the second surface 22, the diameter of the through hole 26 gradually increases, the height of the protrusions 27 protruding from the inner wall of the through hole 26 gradually increases, and the width of the protrusions 27 in the circumferential direction of the through hole 26 gradually increases.

[0067] The following describes the processing method of the side structure 100 in this embodiment 2.

[0068] Step 1: Perform structural parameter modeling on the printing plate 20.

[0069] Specifically, the three-dimensional data of the printing plate 20 is input, and the thickness of the printing plate 20 is set to 3mm to ensure the structural strength of the 3D print and meet the strength requirements of the modification. Figure 9 As shown.

[0070] The outer contour boundary of the printing plate 20 is offset outward by 15mm from the outline of the filling port 23. The outer surface (first surface 21) of the printing plate 20 is used as the reference plane. At the edge of the printing plate 20, the printing plate 20 is recessed by 0.65mm in the thickness direction, so that the edge area of ​​the printing plate 20 is designed as a flange edge 28. The side surface of the flange edge 28 facing outward of the vehicle body is used as the adhesive surface for bonding with the side panel 10. Rectangular ribs 25 are evenly distributed in an array at 40mm intervals on the adhesive surface. The protrusion 27 of the ribs 25 has a height of 0.2mm. The ribs 25 are used to ensure the uniform thickness of the structural adhesive layer during bonding, ensure the flatness of the bonding between the side panel 10 and the printing plate 20, reduce the time for subsequent sanding and finishing, and improve work efficiency. The flange edge 28 is designed with multiple through holes 26 extending along the thickness direction. These through holes 26 are evenly distributed in an array on the flange edge 28 as anchoring holes, increasing the contact area of ​​the structural adhesive to form an anchoring structure and enhance the tensile strength of the structure. Figure 11 and Figure 12 As shown.

[0071] Step 2: Use the scribing tool 4 to position and cut the installation opening 11 on the side panel 10.

[0072] Specifically, such as Figures 13-15 As shown, the marking fixture is positioned and installed on the side panel 10 using two locating pins. A marker is used to draw a line along the inner side of the marking fixture 4. The marking dimension = the inner edge dimension of the flange edge 28 + 0.1mm assembly clearance. Figure 13 As shown.

[0073] Using a cutting tool, precise holes are made according to the drawn lines to form the installation opening 11, and the cut is protected.

[0074] Step 3: 3D print the printing plate 20 and assemble and connect the printing plate 20 with the side panel 10.

[0075] Specifically, the printing plate 20 is printed quickly using SLS laser nylon powder sintering technology. Structural adhesive is applied to the outer surface of the flange edge 28 of the printing plate 20, with the adhesive thickness controlled by the ribs 25 to be 0.2mm~0.3mm. The printing plate 20 is then aligned and assembled with the side panel 10. Adhesive is applied into the through hole 26 on the side of the printing plate 20 facing away from the side panel 10 to form an adhesive anchoring structure within the through hole. Multiple magnetic components 3 are arranged on both the inner and outer sides of the side structure 100. The magnetic components 3 can be neodymium iron boron magnets. These magnetic components 3 are spaced apart circumferentially on the printing plate 20 and arranged in groups opposite each other in the thickness direction of the side structure 100. For example, the multiple magnetic components 3 are arranged in an array with an 80mm spacing, and the printing plate 20 and side panel 10 are held together by magnetic attraction on both the inner and outer sides of the side structure 100. Figure 8 As shown; let stand for 6 hours until the structural adhesive is fully cured.

[0076] The side panel structure 100 of this embodiment not only introduces 3D printing technology to form the printed plate 20, changing the traditional method of relying on sheet metal stamping, but also quickly obtains the required printed plate 20 with the filling port 23 through 3D printing, eliminating the need to make expensive stamping molds, greatly reducing costs and shortening the cycle. Furthermore, a trumpet-shaped through hole 26 is designed on the flange edge 28, and radial toothed protrusions 27 are arranged inside the through hole 26 to increase the contact area of ​​the structural adhesive, forming an anchoring structure and enhancing structural tensile strength. In addition, the raised ribs 25 on the flange edge 28 ensure the uniform distribution of the structural adhesive layer, improving the bonding effect and flatness, and reducing subsequent processing steps.

[0077] The side structure 100 in this embodiment has higher structural reliability and is suitable for prototype vehicles in the engineering verification stage.
