Detailed Implementation

[0033] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0034] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," and "right" indicate orientations or positional relationships based on the drawing directions shown in the accompanying drawings. These terms are used solely for the convenience of describing this disclosure and for simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational construction and operation. Therefore, they should not be construed as limitations on this disclosure. The terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures. The first direction can be the length direction of the panel, and the second direction can be the height direction of the panel; see references for details. Figure 1 and Figure 2 As shown.

[0035] Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “connect,” “link,” and “install” should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection.

[0037] The connection can be direct or indirect, via an intermediate medium. Those skilled in the art can understand the specific meaning of the terms used in this disclosure based on the specific circumstances.

[0038] In related technologies, the installation of trim strips is usually done manually using a simple snap-fit ​​structure. However, due to the lack of an effective positioning structure, installation deviations are prone to occur during the trim strip assembly process, causing problems such as misalignment, loosening, or even detachment of the trim strips, which affects the user experience.

[0039] Based on this, refer to Figures 1 to 6 As shown, according to a first aspect of the present disclosure, a trim assembly 1 is provided, including a trim 10 and a trim mounting structure 20. The trim mounting structure 20 is used to connect to an outer body panel 200. The trim 10 is snapped onto the trim mounting structure 20. A positioning member 30 is provided on one of the trim 10 and the trim mounting structure 20, and a positioning mating member 40 is provided on the other of the trim 10 and the trim mounting structure 20. The positioning mating member 40 is used to cooperate with the positioning member 30 to restrict the degree of freedom of the trim 10.

[0040] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: by setting positioning member 30 and positioning mating member 40 on the trim strip 10 and the trim strip mounting structure 20 respectively, the positioning member 30 and the positioning mating member 40 can restrict the degree of freedom of the trim strip 10 during the assembly process of the trim strip 10 by snap-fit, thereby positioning the trim strip 10 to the accurate installation position. On the one hand, it can avoid the trim strip 10 from shifting or shaking during the installation process, thus improving the accuracy of the trim strip 10 installation. On the other hand, it can greatly improve the assembly efficiency of the trim strip 10 by eliminating the need to compare and calibrate the position of the trim strip 10 during the installation process.

[0041] The aforementioned positioning fitting 40 is used to cooperate with the positioning fitting 30 to restrict the degree of freedom of the trim strip 10. This restriction can be done during the assembly of the trim strip 10 or after the trim strip 10 is assembled, thereby limiting the relative displacement between the trim strip 10 and the trim strip mounting structure 20, and achieving the purpose of improving the connection stability between the two.

[0042] This disclosure does not limit the specific structure and mating method of the positioning element 30 and the positioning mating element 40. For example, in one embodiment provided by this disclosure, the positioning element 30 is a protruding structure, and the positioning mating element 40 is a recessed structure adapted to the shape of the protruding structure. The adaptation design of the protruding structure and the recessed structure can provide guidance and direction during the assembly process of the trim strip 10. The operator only needs to align the protruding structure with the recessed structure to quickly complete the assembly without complicated adjustments and calibrations, which can significantly improve the assembly efficiency.

[0043] Alternatively, in another exemplary embodiment provided in this disclosure, the positioning element 30 may be a wedge block, and the positioning mating element 40 may be a wedge groove. The inclined walls of the wedge block and the wedge groove cooperate with each other. When the wedge block is inserted into the wedge groove, positioning is achieved through the guiding effect of the inclined walls.

[0044] Alternatively, in the third embodiment provided in this disclosure, the positioning of the two can also be achieved by magnetic attraction. For example, permanent magnets are respectively provided on the trim strip 10 and the trim strip mounting structure 20. During the installation of the trim strip 10, the two permanent magnets attract each other, so that the trim strip 10 is in the position to be installed, thereby achieving the positioning of the trim strip 10.

[0045] In one exemplary embodiment provided in this disclosure, such as Figure 2 As shown, the positioning element 30 can be a positioning post 31, which is located on the side of the trim strip 10 near the trim strip mounting structure 20. The positioning mating element 40 can be a positioning hole 41, which is formed on the trim strip mounting structure 20. During the assembly of the trim strip 10, it is only necessary to align the positioning post 31 with the positioning hole 41. This structure is simple and easy to manufacture and assemble. The mating of the positioning post 31 and the positioning hole 41 can provide a reliable positioning effect, facilitating the quick and accurate docking of the trim strip 10 and the trim strip mounting structure 20.

[0046] Furthermore, since the positioning post 31 is located on the side of the trim strip 10 close to the trim strip mounting structure 20, after the trim strip 10 is assembled onto the trim strip mounting structure 20, the trim strip 10 can also cover the positioning post 31 and the positioning hole 41, thereby avoiding the positioning post 31 and the positioning hole 41 from affecting the aesthetics of the vehicle body.

[0047] To further improve the precision of the trim strip 10 assembly process, in the embodiments provided in this disclosure, such as... Figure 5 , Figure 6 As shown, the positioning hole 41 can be a non-circular hole, and the cross-sectional shape of the positioning post 31 matches the shape of the positioning hole 41. By setting the positioning hole 41 as a non-circular hole, and ensuring that the cross-sectional shape of the positioning post 31 matches the shape of the positioning hole 41 (i.e., the cross-section of the positioning post 31 is also non-circular), rotation of the positioning post 31 within the positioning hole 41 can be prevented during the assembly of the trim panel 11. This ensures that the trim strip 10 will not deviate in position due to rotation during installation, further enhancing the reliability of the installation process and improving the accuracy and stability of the trim strip 10 installation.

[0048] In one exemplary embodiment provided in this disclosure, such as Figure 5 As shown, the positioning hole 41 can be formed into a rectangle. On the one hand, the rectangular hole structure is simple and easy to process. On the other hand, when the positioning post 31, which matches the shape of the rectangular positioning hole 41, is inserted into the rectangular hole, the positioning post 31 can be prevented from rotating in the rectangular hole, thereby achieving the purpose of improving the stability of the fit between the positioning post 31 and the positioning hole 41.

[0049] In other embodiments provided in this disclosure, the positioning hole 41 may also be formed as a triangular hole, a square hole or other polygonal hole, or the positioning hole 41 may also be formed as an elliptical hole or an oblong hole. In short, as long as the positioning hole 41 is not a perfectly circular hole, this disclosure does not limit the specific shape of the positioning hole 41.

[0050] To facilitate the fit between the positioning pin 31 and the positioning hole 41, in this disclosure, as follows: Figure 6 As shown, at least one notch 310 is formed on the positioning post 31 to reduce the contact area between the outer peripheral surface of the positioning post 31 and the hole wall of the positioning hole 41 during the assembly of the trim 10. On the one hand, the design of the notch 310 directly reduces the contact area between the positioning post 31 and the positioning hole 41, thereby reducing the frictional resistance during assembly and making the assembly smoother. On the other hand, it can also reduce the amount of material used to manufacture the positioning post 31, thereby reducing the manufacturing cost and overall weight of the trim assembly 1.

[0051] It should be noted that the notch 310 can extend along the axial direction of the positioning post 31 or along the radial direction of the positioning post 31, and this application does not limit it in this regard.

[0052] In one exemplary embodiment where the notch 310 extends axially along the positioning post 31, such as Figure 6 As shown, the cross-sectional shape of the positioning post 31 can be formed as a cross. That is, it is equivalent to forming four spaced notches 310 on the positioning post 31, thereby reducing the contact area between the positioning post 31 and the positioning hole 41 during assembly, and achieving the purpose of reducing the friction between the two during assembly.

[0053] Alternatively, in other embodiments provided in this disclosure, the cross-section of the positioning post 31 can also be formed into other shapes such as the "I" shape that meet the requirements. In short, this disclosure does not limit the specific shape of the positioning post 31, as long as the contact area between the positioning post 31 and the positioning hole 41 can be reduced.

[0054] To facilitate the insertion of the positioning pin 31 into the positioning hole 41, such as Figure 4 , Figure 6As shown, the positioning post 31 may include a main body 311 and a guide portion 312 connected to each other. The main body 311 is connected between the trim strip 10 and the guide portion 312. Along the direction away from the main body 311, the outer diameter of the guide portion 312 gradually decreases. The outer diameter of the guide portion 312 gradually decreases along the direction away from the main body 311, forming a shape similar to a cone or frustum. In this way, during the assembly process, the guide portion 312 can be more easily aligned with the entrance of the positioning hole 41. Even if there is a certain initial positional deviation between the positioning post 31 and the positioning hole 41, the guide portion 312 can naturally slide into the positioning hole 41 by virtue of its gradually decreasing outer diameter, helping to quickly achieve initial positioning, reducing assembly difficulty (especially suitable for some assembly environments with limited space or inconvenient operation), and improving assembly accuracy and efficiency.

[0055] In this disclosure, the snap-fit ​​structure between the trim strip 10 and the trim strip mounting structure 20 is not limited. For example, in one embodiment provided in this disclosure, such as... Figure 3 , Figure 4 As shown, at least one hook 50 is provided on the side of the trim strip 10 near the trim strip mounting structure 20. The trim strip mounting structure 20 includes a fixed section 22 and at least one locking strip 23 connected to each other. The fixed section 22 is used to connect with the vehicle body outer panel 200. Each locking strip 23 can be engaged with its corresponding hook 50 to restrict the hook 50 from moving away from the fixed section 22. By engaging the hook 50 on the trim strip 10 and the locking strip 23 formed on the trim strip mounting structure 20, the movement of the hook 50 away from the fixed section 22 is restricted, thereby achieving relative fixation between the trim strip 10 and the fixed section 22, ensuring the stability of the trim strip 10 after installation, and preventing the trim strip 10 from loosening or falling off during use.

[0056] Furthermore, in the aforementioned implementation where there are multiple hooks 50 and multiple clips 23, the cooperation between multiple hooks 50 and clips 23 can fasten the frame body 12 and the fixing section 22 from different positions, which can further improve the connection stability between the trim strip 10 and the fixing section 22, thereby improving the connection stability between the trim strip 10 and the vehicle body outer panel 200.

[0057] In another embodiment provided in this disclosure, the trim strip 10 and the trim strip mounting structure 20 can also be connected by a spring clip. For example, a spring clip is provided on the side of the trim strip 10 near the trim strip mounting structure 20, and a locking block is provided on the side of the trim strip mounting structure 20 near the trim strip 10. The spring clip clamps the locking block by elastic deformation to achieve snap-fit ​​fixation.

[0058] In one exemplary embodiment provided in this disclosure, the number of the aforementioned hooks 50 and strips 23 are two.

[0059] This disclosure does not limit the shape and specific structure of the hook 50 described above. For example, in one exemplary embodiment provided in this disclosure, such as... Figure 3 , Figure 4 as well as Figure 6 As shown, the hook 50 can be formed in a wedge shape, and a bevel 51 for guiding the hook 23 is formed on the side of the hook 50 near the hook strip 23. In this way, during the process of assembling the trim strip 10 onto the trim strip mounting structure 20, the hook strip 23 abuts against the bevel 51 of the hook 50. At this time, the bevel 51 can play a guiding role, allowing the hook strip 23 to slide along the outer surface of the hook 50 under pressure until it locks with the hook 50.

[0060] Optionally, such as Figure 6 As shown, a through hole 120 is formed on the skeleton body 12, extending along its own thickness direction. The hook 50 is connected to the skeleton body 12 and is at least partially located within the through hole 120. On the one hand, by placing the hook 50 within the through hole 120 of the skeleton body 12, a certain amount of space can be provided for the deformation of the hook 50 during the engagement process with the clip 23, avoiding interference or interference from the skeleton body 12 when the hook 50 is engaged with the clip 23, thus affecting the normal assembly of the two. On the other hand, providing the through hole 120 on the skeleton body 12 can reduce the weight of the skeleton body 12, thereby reducing the production cost and weight of the aforementioned trim assembly 1.

[0061] Optionally, such as Figure 6 As shown, the frame body 12 may also include a reinforcing rib 121, which is disposed within the through hole 120 and connected to the inner wall of the through hole 120. The hook 50 is connected to the reinforcing rib 121. The reinforcing rib 121 within the through hole 120 of the frame body 12 strengthens the connection between the hook 50 and the frame body 12, improves the stability of the connection between the hook 50 and the frame body 12, and ensures that the hook 50 will not easily deform or cause the frame body 12 to deform when subjected to external forces, thereby guaranteeing the overall performance of the trim strip 10.

[0062] Furthermore, since the reinforcing rib 121 is also located within the through hole 120, when the locking strip 23 engages with the hook 50 (the locking strip 23 is also located within the through hole 120 at this time), the reinforcing rib 121 can limit the locking strip 23 from one side, thereby restricting the range of motion of the locking strip 23 within the through hole 120 when it engages with the hook 50, thus improving the accuracy and stability of the engagement.

[0063] Optionally, such as Figure 3 , Figure 4As shown, the trim installation structure 20 may include a positioning section 21 and a fixing section 22. The fixing section 22 is used to connect with the vehicle body outer panel 200. The positioning section 21 is connected to the fixing section 22 and spaced apart from the vehicle body outer panel 200. One of the positioning element 30 and the positioning mating element 40 is disposed on the positioning section 21. Spacing the positioning section 21 away from the vehicle body outer panel 200 provides sufficient space for the installation and use of the positioning element 30 and the positioning mating element 40, avoiding interference between the positioning element 30 or the positioning mating element 40 and the vehicle body outer panel 200 during the positioning process.

[0064] In the embodiment where the positioning fitting 40 is formed as a positioning hole 41, the positioning hole 41 can be formed on the positioning segment 21, that is, the positioning hole 41 penetrates along the thickness direction of the positioning segment 21.

[0065] In one embodiment provided in this disclosure, the aforementioned fixed section 22 can be connected to the vehicle body outer panel 200 by spot welding.

[0066] Furthermore, the aforementioned positioning section 21 and fixing section 22 can be manufactured as a single piece. The single-piece design gives the mounting structure 20 higher strength and makes it easier to produce and manufacture the mounting structure 20.

[0067] In one exemplary embodiment provided in this disclosure, such as Figure 5 As shown, the above-mentioned trim installation structure 20 may include two fixing sections 22. One fixing section 22 is connected to one end of the positioning section 21, and the other fixing section 22 is connected to the other end of the positioning section 21. On the one hand, it can achieve a better connection and support effect for the positioning section 21. On the other hand, the two fixing sections 22 can each form the above-mentioned clip 23 at the end away from the positioning section 21.

[0068] Optionally, the trim strip 10 is provided with a hook 50, and the trim strip mounting structure 20 also includes a clip 23 for cooperating with the hook 50. One end of the clip 23 is connected to the end of the fixing section 22 opposite to the positioning section 21, such as... Figure 5 As shown, the other end of the locking strip 23 extends towards the hook 50 to engage with it. During installation, the locking strip 23 extending towards the hook 50 has a certain elasticity. When the locking strip 23 contacts the hook 50, it deforms to one side, allowing it to pass smoothly over the hook 50. After passing the hook 50, the locking strip 23 returns to its original shape due to its elasticity and presses against the hook 50, thus stopping and limiting the hook 50. This automatic avoidance and reset feature greatly simplifies the installation process, allowing for the connection between components without complicated operations, and improving installation efficiency.

[0069] Furthermore, because the clip 23 can deform elastically, even if there is a certain deviation in the initial position between the clip 23 and the hook 50 during the installation process, the clip 23 can adapt to this deviation by deformation and effectively abut against the hook 50, thereby reducing the requirements for installation accuracy and reducing the debugging time and difficulty during the installation process.

[0070] Furthermore, in the embodiment where the hook 50 has a slope 51 on one side, during the contact process between the hook strip 23 and the hook strip 50, the slope 51 will generate a lateral component force on the hook strip 23. The hook strip 23 has a certain elasticity. Under the action of this component force, the hook strip 23 will deform and move to one side, so that the hook strip 23 can pass over the hook 50 more smoothly.

[0071] Optionally, such as Figures 2 to 4 As shown, the trim assembly 1 may further include a first sealing structure 90, which is connected between the trim 10 and the vehicle body outer panel 200. The side of the first sealing structure 90 facing away from the trim 10 abuts against the vehicle body outer panel 200. A first stepped structure 91 is formed on the side of the first sealing structure 90 near the trim 10, and a second stepped structure 122 is formed on the side of the trim 10 near the first sealing structure 90. The first stepped structure 91 and the second stepped structure 122 are interlocked. By interlocking the first stepped structure 91 and the second stepped structure 122, the sealing path can be increased, the sealing area and sealing effect between the edge of the trim 10 and the vehicle body outer panel 200 can be improved, thereby enhancing the sealing effect between the trim assembly 1 and the vehicle body outer panel 200, preventing rainwater, dust, etc. from entering the vehicle body interior, and protecting the vehicle body structure and interior from damage.

[0072] Furthermore, for embodiments of the trim strip including the trim panel 11 and the frame body 12, such as Figure 2 As shown, the aforementioned second stepped structure 122 can be formed on the edge of the lower end face of the skeleton body 12.

[0073] It should be noted that this disclosure does not limit the specific material of the first sealing structure 90. For example, the first sealing structure 90 can be made of flexible materials such as rubber and silicone, so that when the first sealing structure 90 is pressed against the outer panel 200 of the vehicle body, the first sealing structure 90 can deform and press against the outer panel 200 of the vehicle body.

[0074] In one exemplary embodiment provided in this disclosure, the first sealing structure 90 may be a sealing strip.

[0075] According to a second aspect of the present disclosure, a vehicle body structure is provided, including an outer body panel 200 and a trim assembly 1 as described above, the trim assembly 1 being mounted on the outer body panel 200. This vehicle body structure possesses all the beneficial effects of the trim assembly 1 described above, and can improve the overall aesthetics and sealing of the vehicle body structure.

[0076] Optionally, the body structure may include at least one pair of trim assemblies 1, each pair of trim assemblies 1 being symmetrically arranged about the longitudinal centerline of the outer body panel 200. The symmetrical arrangement of the trim assemblies 1 can make the body appearance more harmonious and aesthetically pleasing, enhancing the overall visual effect of the vehicle.

[0077] This disclosure does not limit the specific placement of the aforementioned trim component 1. For example, in one embodiment provided in this disclosure, such as... Figure 1 , Figure 5 As shown, the vehicle body outer panel 200 may include a roof outer panel 210 and a side outer panel 220. The roof outer panel 210 overlaps with the side outer panel 220. The trim assembly 1 covers the roof outer panel 210 and the side outer panel 220. A second sealing structure is provided between the roof outer panel 210 and the side outer panel 220, as well as at the connection points between the roof outer panel 210 and the side outer panel 220. The overlap and connection points between the roof outer panel 210 and the side outer panel 220 are critical areas where rainwater may seep into the vehicle interior. Providing a second sealing structure at the overlap and connection points of the roof outer panel 210 and the side outer panel 220 can effectively block rainwater, prevent rainwater from flowing into the vehicle interior through these gaps, maintain a dry environment inside the vehicle, protect electronic equipment, interior trim, etc., from water corrosion, and extend their service life.

[0078] Similarly, this disclosure does not limit the specific material of the second sealing structure, as long as it can achieve the effect of blocking rainwater.

[0079] In one exemplary embodiment provided in this disclosure, the aforementioned roof outer panel 210 may include a roof body 211 and a roof overlapping edge 212, and the side outer panel 220 may include a side body 221 and a side overlapping edge 222. The roof overlapping edge 212 overlaps with the side overlapping edge 222 to form a strip-shaped groove structure. The trim assembly 1 covers the roof overlapping edge 212 and the side overlapping edge 222 and is located within the strip-shaped groove structure. On the one hand, by covering the roof overlapping edge 212 and the side overlapping edge 222 with the trim assembly 1, the roof overlapping edge 212 and the side overlapping edge 222 can be protected from erosion and damage by the external environment. On the other hand, because the trim assembly 1 is located within the strip-shaped groove structure, the vehicle body appearance can be made smoother and more streamlined, improving the overall aesthetics of the vehicle.

[0080] In other embodiments provided in this disclosure, the trim assembly 1 may also be placed between the front outer panel and the top outer panel 210 or between the rear outer panel and the top outer panel 210.

[0081] In the embodiment where the vehicle body outer panel 200 may include a roof outer panel 210 and a side outer panel 220, and the roof outer panel 210 includes a roof body 211 and a roof overlap edge 212, the aforementioned fixing section 22 may be fixedly connected to the roof overlap edge 212 by spot welding.

[0082] The second sealing structure mentioned above may include a spot welding sealant layer 70 and a weld sealant layer 80. The spot welding sealant layer 70 can seal the gaps generated by spot welding between the top cover outer panel 210 and the side panel outer panel 220, while the weld sealant layer 80 can seal the connection between the top cover outer panel 210 and the side panel outer panel 220 (such as the weld seam).

[0083] In one embodiment provided in this disclosure, the top cover overlap edge 212 and the side wall overlap edge 222 are connected by spot welding, such as... Figures 2 to 4 As shown, the aforementioned spot-welded sealant layer 70 is provided between the overlapping edge 212 of the roof and the overlapping edge 222 of the side wall. By providing the spot-welded sealant layer 70 between the overlapping edge 212 of the roof and the overlapping edge 222 of the side wall, the spot-welded sealant layer 70 can fill the gaps generated during the spot welding process, forming an effective sealing barrier to prevent moisture from entering the vehicle body from the spot weld and protect the internal structure of the vehicle body from water damage.

[0084] In the embodiments provided in this disclosure, the connection between the top cover outer plate 210 and the side wall outer plate 220 mentioned above can be the weld seam between the top cover outer plate 210 and the side wall outer plate 220, such as... Figures 2 to 4 As shown in this disclosure, the edge of the roof overlap 212 opposite to the roof body 211 has a weld, and the weld is covered with the aforementioned weld sealant layer 80. Since the weld at the edge of the roof overlap 212 opposite to the roof body 211 is also a potential leakage channel, in one embodiment provided in this disclosure, the weld sealant layer 80 is covered on the weld to seal it, thereby preventing rainwater and other liquids from seeping between the roof outer panel 210 and the side panel 220, further enhancing the waterproof performance of the vehicle body, ensuring that the interior of the vehicle remains dry, and improving the comfort of vehicle use.

[0085] A vehicle is provided according to a third aspect of the present disclosure, including the trim assembly 1 as described above or the body structure as described above. The vehicle has all the beneficial effects of the trim assembly 1 and the body structure described above.

[0086] In addition, the vehicles mentioned above can be cars, trucks, vans, etc., and can be pure electric vehicles, hybrid electric vehicles (range-extended electric vehicles), etc. This disclosure does not limit them.

[0087] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0088] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0089] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
