Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a shark fin shell protective structure and vehicle. Background Technology

[0002] In existing technologies, most measures for protecting the T-BOX shark fin shell involve attaching 3M adhesive to the inner wall of the shark fin shell, then pre-fixing it to the shark fin shell's fittings using the 3M adhesive, passing bolts through bolt holes, and locking nuts onto the bolts to achieve a tight seal, thus providing dust and water protection and meeting the IP69K protection rating.

[0003] However, this structural design leads to the following problems: First, the use of 3M adhesive increases costs; second, 3M adhesive is difficult to bond to the inner wall of the shark fin shell, and the shell is prone to deformation after the protective film is removed; third, the adhesive component of 3M adhesive will undergo qualitative changes in harsh environments, resulting in poor dustproof and waterproof performance.

[0004] Therefore, a shark fin shell protective structure needs to be designed to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a shark fin shell protective structure and vehicle, which effectively solves the problems of high cost, complicated assembly and poor dust and water protection effect of the existing shark fin shell protective structure in some usage scenarios.

[0006] According to a first aspect of the present invention, a shark fin shell protective structure is provided, wherein the shark fin shell protective structure includes a shell body, a counter piece, and a connector. The shell body has a connecting groove on a first end face facing the counter piece, the connecting groove being recessed from the first end face toward a direction away from the counter piece. The counter piece has a snap-fit ​​protrusion on a second end face facing the shell body, the snap-fit ​​protrusion being protruded from the second end face toward a direction closer to the shell body, and the snap-fit ​​protrusion being engaged with the connecting groove. Both the shell body and the counter piece have connecting portions, and the connector passes through the connecting portions to lock the connector and the counter piece.

[0007] Preferably, the outer shell body includes an outer wall portion and a clamping portion, and the connecting groove is disposed between the outer wall portion and the clamping portion; the connecting groove includes a groove bottom connecting the outer wall portion and the clamping portion, and the groove bottom is formed into a triangular structure so that the wall thickness of the outer wall portion is uniform.

[0008] Preferably, the snap-fit ​​protrusion is formed as a protrusion groove, and the opening of the protrusion groove is in the same direction as the opening of the connecting groove.

[0009] Preferably, when the connecting groove engages with the snap-fit ​​protrusion, the connecting groove is sealed by the snap-fit ​​protrusion to form a double stop structure.

[0010] Preferably, the bottom of the raised groove is formed into a pointed structure, which is accommodated inside the triangular structure.

[0011] Preferably, the outer periphery of the snap-fit ​​protrusion is provided with a mating groove, which corresponds to the first end face of the outer shell body.

[0012] Preferably, the connecting groove surrounds the first end face of the housing body, and the snap-fit ​​protrusion surrounds the second end face of the counter piece.

[0013] Preferably, both the number of connecting portions and the number of connecting members are multiple, and the multiple connecting portions are evenly distributed on the outer shell body and the connecting member.

[0014] Preferably, the width of the connecting groove is greater than the width of the snap-fit ​​protrusion.

[0015] According to a second aspect of the present invention, a vehicle is provided, wherein the vehicle includes the shark fin shell protective structure as described above.

[0016] According to this utility model, the shark fin shell protective structure, through the cooperation of the shell body, the connecting parts, and the connectors, can achieve dust and water protection for the shark fin area on the vehicle body, reaching an IP69K protection level. The connecting grooves of the shell body and the snap-fit ​​protrusions of the connecting parts replace the 3M adhesive used in the original technology, thus solving the technical defects caused by 3M adhesive bonding. The snap-fit ​​connecting grooves and protrusions enable pre-positioning during assembly and meet the protection level requirements. The structural connection, improved from uncertain adhesive bonding to snap-fit, greatly enhances the assemblability of the product.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] According to a first aspect of this utility model, a shark fin shell protective structure is provided, such as... Figures 1 to 4 As shown, this shark fin shell protective structure is used in vehicles. The shark fin shell protective structure includes a shell body 1, a connecting member 2, and a connector 301. In the following description, reference will be made to... Figures 1 to 4 This section describes the detailed structure of the shark fin shell protective structure, including the shell body 1, the hand piece 2, and the connector 301.

[0030] like Figures 1 to 4 As shown, in this embodiment, the outer shell body 1 and the mating member 2 can be two components that abut against each other. When the outer shell body 1 and the mating member 2 are connected, the outer shell body 1 is located on the outside of the vehicle body 4 (e.g., the roof), and the mating member 2 is located inside the vehicle body 4.

[0031] Specifically, the outer shell body 1 has a connecting groove 101 on its first end face facing the opposing component 2. The connecting groove 101 is recessed from the first end face away from the opposing component 2. The opposing component 2 has a snap-fit ​​protrusion 201 on its second end face facing the outer shell body 1. The snap-fit ​​protrusion 201 protrudes from the second end face towards the outer shell body 1. Both the outer shell body 1 and the opposing component 2 can be shaped like a shark fin, with a pointed tip and a rounded tail. The first end face and the second end face are the end faces where the outer shell body 1 and the opposing component 2 mate with each other. The snap-fit ​​protrusion 201 can be snapped into the inside of the connecting groove 101 to seal the connection between the outer shell body 1 and the opposing component 2, thereby ensuring the sealing performance inside the outer shell body 1. In addition, when assembling the outer shell body 1 and the opposing component 2 on the vehicle body 4, the connecting groove 101 and the snap-fit ​​protrusion 201 can be used for initial positioning, facilitating the insertion of the connecting component 301.

[0032] Furthermore, both the outer casing 1 and the opposing member 2 are provided with connecting portions 302. The connecting member 301 passes through the connecting portion 302 to lock the connecting member 301 and the opposing member 2. The connecting portion 302 can be, for example, a connecting position with a through hole. This connecting position is specially designed with a convex washer structure to facilitate the fixing of the connecting member 301, which is formed as a bolt and nut. The connecting member 301 can be, for example, a welded bolt and nut. One end of the welded bolt can be fixed to the connecting portion 302 with the through hole in the outer casing 1, and the other end of the welded bolt can pass through the connecting portion 302 of the opposing member 2 and engage with the nut to achieve locking and fixing of the outer casing 1 and the opposing member 2.

[0033] This shark fin protective shell structure, through the cooperation of the shell body 1, the connecting parts 2 and 301, achieves dust and water protection for the shark fin area on the vehicle body 4. The connecting groove 101 of the shell body 1 and the snap-fit ​​protrusion 201 of the connecting parts 2 replace the 3M adhesive used in the original technology, thus solving the technical defects caused by 3M adhesive bonding. The snap-fit ​​connecting groove 101 and the snap-fit ​​protrusion 201 enable pre-positioning during assembly and meet protection level requirements. The structural connection, improved from uncertain adhesive bonding to a snap-fit ​​connection, greatly enhances the product's assemblability. This shark fin protective shell structure has a simple overall structure and is easy to assemble, solving the problem of pre-positioning during installation and reducing cost.

[0034] Preferably, such as Figure 2 and Figure 4 As shown, in this embodiment, the outer casing body 1 may include an outer wall portion 102 and a clamping portion 103. A connecting groove 101 is disposed between the outer wall portion 102 and the clamping portion 103. Alternatively, it can be understood that the outer wall portion 102 and the clamping portion 103 are formed on the first end face of the outer casing body 1 because the connecting groove 101 is provided. Further, the connecting groove 101 may include a groove bottom connecting the outer wall portion 102 and the clamping portion 103. The groove bottom is formed into a triangular structure to ensure that the wall thickness of the outer wall portion 102 is uniform. In order to ensure the uniformity of the overall rear wall of the outer wall portion 102 of the outer casing body 1, the connecting groove 101 is not a conventional cuboid groove, but a groove with a triangular bottom and an overall right-angled trapezoidal structure, thereby ensuring that the thickness of the overall outer wall of the outer casing body 1 is uniform even though the connecting groove 101 is provided.

[0035] Preferably, such as Figure 4 As shown, in this embodiment, the snap-fit ​​protrusion 201 is formed as a protrusion groove, and the opening of the protrusion groove is in the same direction as the opening of the connecting groove 101. The groove wall and the bottom of the protrusion groove are both the second end face of the contact member 2, that is, the snap-fit ​​protrusion 201 can be understood as the second end face of the contact member 2 protruding upward as a whole to form a groove-like protrusion.

[0036] Preferably, such as Figure 4and Figure 5 As shown, in this embodiment, when the connecting groove 101 engages with the snap-fit ​​protrusion 201, the groove of the connecting groove 101 is sealed by the snap-fit ​​protrusion 201 to form a double-stop structure. The double-stop structure can be, for example,... Figure 5 As shown, the two slots are joined together, with the body of one slot housed inside the other, thus ensuring the airtightness of the interiors of the two slots.

[0037] Preferably, such as Figures 2 to 4 As shown, in the embodiment, in order to further facilitate pre-positioning during assembly so that the snap-fit ​​protrusion 201 can be better positioned and connected with the connecting groove 101, the bottom of the snap-fit ​​protrusion 201, which forms a protrusion groove, is formed into a pointed structure, and the pointed structure is accommodated inside the triangular structure.

[0038] Preferably, such as Figure 3 As shown, in this embodiment, a mating groove 202 is provided on the outer periphery of the snap-fit ​​protrusion 201, and the mating groove 202 corresponds to the first end face of the outer shell body 1. That is, the snap-fit ​​protrusion 201 is snapped into the inside of the connecting groove 101 of the outer shell body 1, and the outer wall portion 102 of the outer shell body 1 abuts against the mating groove 202 to ensure the sealing performance when the outer shell body 1 is connected to the matching part 2.

[0039] Preferably, such as Figure 2 and Figure 3 As shown in the embodiment, since both the outer shell body 1 and the locking member 2 can be formed in the shape of a shark fin, in order to ensure the sealing of the connection, the connecting groove 101 surrounds the first end face of the outer shell body 1, and the locking protrusion 201 surrounds the second end face of the locking member 2. The connecting groove 101 and the locking protrusion 201 surround the connection to ensure the stability and sealing of the connection.

[0040] Preferably, such as Figures 1 to 4 As shown, in this embodiment, there are multiple connecting portions 302 and multiple connecting members 301, with the multiple connecting portions 302 evenly distributed on the outer shell body 1 and the matching member 2. Since both the outer shell body 1 and the matching member 2 can be formed in the shape of a shark fin, and both have a pointed tip and an arc-shaped tail end, the number of connecting portions 302 and the number of connecting members 301 can both be three, with one at the pointed tip and the other two symmetrically arranged at the arc-shaped tail end. The line connecting the three connecting portions 302 can form a triangle, thereby ensuring the stability and sealing of the connection between the outer shell body 1 and the matching member 2.

[0041] Preferably, such as Figure 4As shown, in this embodiment, the width of the connecting groove 101 is greater than the width of the snap-fit ​​protrusion 201. The structural dimensions of the snap-fit ​​protrusion 201 are: 7.4mm high × 2.6mm wide, and the structural dimensions of the connecting groove 101 are: 10.2mm high × 3mm wide. To ensure ease of assembly, the snap-fit ​​protrusion 201 is designed with a 1mm × 70° C-angle and a 0.4mm R-angle, as well as a 0.2mm safety gap on one side of its width. Thus, the design of the snap-fit ​​protrusion 201 not only meets the protection level requirements but also provides a pre-positioning function for installation, increasing the accuracy and efficiency of bolt and nut fastening.

[0042] This shark fin protective shell structure, through the cooperation of the shell body, connecting parts, and connectors, achieves dust and water protection for the shark fin area on the vehicle body, reaching an IP69K protection level. The connecting grooves on the shell body and the snap-fit ​​protrusions on the connecting parts replace the 3M adhesive used in previous technologies, thus solving the technical defects of 3M adhesive bonding. The snap-fit ​​connecting grooves and protrusions enable pre-positioning during assembly and meet protection level requirements. The structural connection, improved from uncertain adhesive bonding to snap-fit, greatly enhances the product's assemblability. This shark fin protective shell structure has a simple overall structure and is easy to assemble, solving the problem of pre-positioning during installation and reducing costs.

[0043] Furthermore, according to a second aspect of this utility model, a vehicle is provided, the vehicle including the shark fin outer shell protective structure as described above. During the assembly of the shark fin assembly, the shark fin outer shell protective structure enables rapid assembly of the outer shell body 1 and the matching component 2.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
