Description

Technical Field

[0001] This application relates to the field of vehicle exterior technology, and in particular to a ventilation cover extension plate mounting structure and vehicle. Background Technology

[0002] In the purchase and use of cars, car owners' demands for personalization are increasing, which is also accompanied by a growing demand for aftermarket modifications. Among these modifications, adding decorative items such as spotlights and flags to the ventilation hood extension plate has become a relatively common requirement.

[0003] However, existing ventilation cover extensions are typically made of plastic and fixed to the vehicle body via clips. This structure cannot effectively support the weight of newly added decorative parts, thus failing to meet customers' needs for personalized modifications. Therefore, an installation structure that can provide sufficient support strength and is compatible with later modification requirements is needed. Utility Model Content

[0004] In view of this, this application aims to provide a ventilation cover extension plate mounting structure to improve the support strength between the ventilation cover extension plate and the vehicle body.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A ventilation cover extension plate mounting structure includes a fender, a ventilation cover extension plate, and a mounting bracket; the top of the fender is formed with a top flange, and the ventilation cover extension plate is positioned on the top flange; the mounting bracket includes a main bracket for connecting the ventilation cover extension plate and a nacelle connecting frame for connecting the nacelle frame, the main bracket and the nacelle connecting frame are paired and positioned at the same position on the top flange, and are fixedly connected as a whole by connectors.

[0006] Furthermore, both the main support and the cabin connecting frame are formed by stamping or bending sheet metal together.

[0007] Furthermore, the main support includes an integrally connected bottom plate and a side plate, the ventilation cover extension plate is fixedly connected to the side plate, and the bottom plate is connected to the top of the top flange.

[0008] Furthermore, the side plate is formed with reinforcing ribs, and / or, the connection between the bottom plate and the side plate is provided with reinforcing protrusions.

[0009] Furthermore, the top flange has a clearance notch at the location where the mounting bracket is set, and the bottom plate has a recessed portion formed in the clearance notch; the recessed portion has a first connecting hole for connecting the cabin connecting frame.

[0010] Furthermore, the main support and the cabin connecting frame are fixed together by bolts, and the top flange is clamped between the main support and the cabin connecting frame; the bolts pass through the first connecting hole and the second connecting hole on the cabin connecting frame, and the part of the cabin connecting frame where the second connecting hole is located has a protrusion that extends into the clearance notch.

[0011] Furthermore, the main support is provided with a nut, the outer surface of the ventilation cover extension plate is provided with a groove, and the bottom of the groove is provided with an installation hole. The ventilation cover extension plate is screwed onto the nut by an installation bolt passing through the installation hole.

[0012] Furthermore, along the front-rear direction of the vehicle body, a plurality of mounting brackets are provided at intervals on the top flange, and at least one mounting bracket is provided at the rear end of the top flange.

[0013] Furthermore, the cabin connecting frame located at the rear end of the top flange has a plate facing the rear of the vehicle, and the plate is provided with a third connecting hole for connecting the ventilation cover extension plate.

[0014] Compared with related technologies, this application has the following advantages: (1) The ventilation cover extension plate installation structure of this application provides an installation bracket on the top flange of the fender. The installation bracket consists of a main bracket and a cabin connecting bracket in pairs. The separate arrangement of the brackets facilitates the connection between the cabin connecting bracket and the cabin frame on the side of the vehicle body. By setting the main bracket and the cabin connecting bracket at the same position on the top flange and connecting them together with the connector, the installation bracket can be firmly installed on the fender and the connection between the installation bracket and the vehicle body can be guaranteed. This provides strong support for the installation of the ventilation cover extension plate on the fender. When the ventilation cover extension plate is connected to the main bracket, the support strength between the ventilation cover extension plate and the vehicle body can be effectively improved, thus providing favorable conditions for adding decorative parts on the ventilation cover extension plate.

[0015] (2) The main support and the cabin connecting frame in the installation bracket are both made of sheet metal stamping or bending, which makes it easy to use high-strength sheet metal such as steel plate as raw material to efficiently process the required shape of the bracket, thereby obtaining a bracket structure with good support performance.

[0016] (3) The main bracket adopts a right-angle bending structure similar to angle iron. The bottom plate can be mated with the top flange, and the side plate is located in a position that facilitates connection with the ventilation cover extension plate. Connecting the main bracket to the top flange through the bottom plate provides good conditions for the installation of the ventilation cover extension plate on the fender and its connection with the mounting bracket.

[0017] (4) By setting some reinforcing ribs or reinforcing protrusions at appropriate positions on the main support, the overall structural stability of the support can be effectively enhanced.

[0018] (5) By setting a clearance notch at the position where the mounting bracket needs to be set on the top flange, and correspondingly setting a recessed part on the bottom plate of the main bracket, the recessed part can be restricted within the clearance notch; then, a first connecting hole is set on the recessed part. When the main bracket and the cabin connecting frame are connected together by the connector that passes through the first connecting hole, the stability of the entire mounting bracket on the top flange can be further improved by the limiting effect of the clearance notch.

[0019] (6) The main support and the cabin connecting frame are connected as one unit by bolt pairs. At the same time, the main support and the cabin connecting frame are respectively set on the upper and lower sides of the top flange, which can effectively clamp the top flange in the middle. With the limiting effect of the above-mentioned avoidance gap, as well as the sinking part set on the main support and the protrusion set on the cabin connecting frame, the various limiting, avoidance and reinforcement structures are tightly connected by bolt pairs to form a stable connection, which can further improve the installation firmness of the mounting bracket on the hospital gown.

[0020] (7) Nuts are provided on the main bracket, specifically on the side plate, and screwed into the mounting bolts that pass through the ventilation cover extension plate, so that the ventilation cover extension plate can be reliably connected to the mounting bracket. By setting a groove on the outer surface of the ventilation cover extension plate, the head of the mounting bolt can be hidden in the groove, avoiding the appearance of a raised structure on the outer surface of the vehicle body, which would affect the cleanliness of the vehicle body surface.

[0021] (8) Multiple mounting brackets are set at intervals on the top flange. The engine compartment connecting bracket in each mounting bracket can be connected to the engine compartment frame on the side of the vehicle body. This forms a multi-point support structure between the vehicle body engine compartment frame and the ventilation cover extension plate, thereby enhancing the structural stability of the ventilation cover extension plate and enabling it to withstand the installation of heavier new decorative parts.

[0022] (9) A third connecting hole is provided on the engine room connecting frame at the tail end of the top flange, and a fourth connecting hole can be provided at the tail end of the ventilation cover extension plate. The tail end of the ventilation cover extension plate can be fixed on the engine room connecting frame by connecting parts passing through the fourth connecting hole and the third connecting hole, so as to improve the installation stability of the tail end of the ventilation cover extension plate.

[0023] Another object of this application is to provide a vehicle equipped with the ventilation cover extension plate mounting structure described in this application. The vehicle of this application possesses the technical advantages of the aforementioned ventilation cover extension plate mounting structure. Attached Figure Description

[0031] With increasing demand for vehicle modifications from car owners, adding decorative elements such as spotlights and flags to the ventilator extension plate has become a common requirement. However, existing ventilator extension plates are typically made of plastic and fixed to the vehicle body via clips. This structure cannot effectively support the weight of the added decorative elements, thus failing to meet customers' personalized modification needs. Therefore, a mounting structure that provides sufficient support strength and is compatible with post-modification requirements is needed.

[0032] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new ventilation cover extension plate installation structure, which can improve the support strength between the ventilation cover extension plate 2 and the vehicle body.

[0033] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0034] An embodiment of the first aspect of this application provides a ventilation cover extension plate mounting structure, which can be applied to the installation scenario of a fender 1 and its ventilation cover extension plate 2; an exemplary structure is as follows: Figure 1 and Figure 2 As shown.

[0035] Overall, the ventilation cover extension plate mounting structure includes a fender 1, a ventilation cover extension plate 2, and a mounting bracket 3. The fender 1 has a top flange 10 formed on its top, and the ventilation cover extension plate 2 is positioned on the top flange 10. The mounting bracket 3 includes a main bracket 31 for connecting the ventilation cover extension plate 2 and a nacelle connecting bracket 32 ​​for connecting the nacelle frame. The main bracket 31 and the nacelle connecting bracket 32 ​​are paired and positioned at the same location on the top flange 10, and are fixed together as a single unit by connectors.

[0036] Based on the overall design concept described above, by setting a mounting bracket 3 on the top flange 10 of the fender 1, and the mounting bracket 3 being a pair of main brackets 31 and engine compartment connecting brackets 32, the separate arrangement of the brackets facilitates the connection between the engine compartment connecting bracket 32 ​​and the engine compartment frame on the side of the vehicle body. By setting the main bracket 31 and the engine compartment connecting bracket 32 ​​at the same position on the top flange 10 and connecting them together, the mounting bracket 3 can be firmly installed on the fender 1, and the connection between the mounting bracket 3 and the vehicle body can be guaranteed to be firm, thus providing strong support for the installation of the ventilation cover extension plate 2 on the fender 1. When the ventilation cover extension plate 2 is connected to the main bracket 31, the support strength between the ventilation cover extension plate 2 and the vehicle body can be effectively improved, thus providing favorable conditions for setting new decorative parts on the ventilation cover extension plate 2.

[0037] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned mounting bracket 3 can adopt a frame structure or a bent plate structure in the shape of angle iron; the connection between the cabin connecting frame 32 and the cabin frame can be screwed or welded. The specific setting sequence and assembly method of the fender 1, the ventilation cover extension plate 2, and the main bracket 31 and cabin connecting frame 32 in the mounting bracket 3 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible design can be carried out by referring to mature setting methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this application.

[0038] To facilitate a better understanding of the contents of this application, it is necessary to provide a prior description of the specific arrangement of the ventilation cover extension plate 2 on the fender 1. The ventilation cover extension plate 2, as the part extending from both ends of the ventilation cover body towards the left and right sides of the vehicle, not only forms a connection between the ventilation cover body and the fender 1, but also creates a good decorative effect on the side of the vehicle.

[0039] like Figure 2 and combined Figure 3 , Figure 4As shown, to improve the overall structural strength of the ventilation cover extension plate 2, the ventilation cover extension plate 2 in this embodiment includes an extension plate body 20 and a reinforcing plate 21 lined inside the extension plate body 20. The reinforcing plate 21 can be configured as a reinforcing bracket, providing good reinforcement and support for the extension plate body 20. During installation, the positioning of the ventilation cover extension plate 2 on the top flange 10 typically adopts a combination of positioning and snap-fit ​​structures. Therefore, the relevant positioning and insertion structures can be set between the top flange 10 and the reinforcing plate 21, with the reinforcing plate 21 connecting and engaging with the top flange 10. The extension plate body 20 covers the outside of the reinforcing plate 21, mainly serving a decorative purpose.

[0040] An insertion plate 202 is provided on the extension plate body 20, and an insertion hole 211 is provided on the reinforcing plate 21. The insertion plate 202 is inserted into the insertion hole 211 to install the extension plate body 20 onto the reinforcing plate 21. In order to improve the reliability of the installation, a snap-fit ​​post 203 can also be provided on the reinforcing plate 21, and a snap-fit ​​groove 212 is provided on the reinforcing plate 21 accordingly. Through the snap-fit ​​cooperation between the snap-fit ​​post 203 and the snap-fit ​​groove 212, the connection between the extension plate body 20 and the reinforcing plate 21 is further improved.

[0041] In this embodiment, the reinforcing plate 21, in addition to connecting the main body of the extension plate 20, also has a fixing frame 216 integrally formed on the bottom inner side of the main body, which connects to the top flange 10. Specifically, positioning holes 101 and locking holes 102 can be provided on the top flange 10, and correspondingly, positioning posts 213 and locking tongues 214 can be provided at the bottom of the fixing frame 216. During installation, the positioning posts 213 are inserted into the corresponding positioning holes 101, and the locking tongues 214 are engaged with the corresponding locking holes 102. These positioning and engaging structures are preferably located close to the mounting bracket 3 to ensure that the ventilation cover extension plate 2 can be more accurately positioned on the top flange 10, improving assembly accuracy.

[0042] Continue as Figures 4 to 8 As shown, as a preferred exemplary implementation among various feasible solutions, both the main support 31 and the cabin connecting frame 32 in this embodiment are formed by stamping or bending sheet metal together. The fact that both the main support 31 and the cabin connecting frame 32 in the mounting bracket 3 are integrally stamped or bent from sheet metal facilitates the efficient processing of brackets of the required shape using high-strength sheet metal such as steel plates as raw materials, thereby obtaining a bracket structure with good support performance.

[0043] For the specific configuration of the main support 31, there are, of course, several different technical solutions to choose from; for example, a rectangular or triangular frame structure. However, to obtain superior technical results, the following configuration is preferred. Figure 8As shown, as a preferred exemplary embodiment among various feasible solutions, the main support 31 of this embodiment includes an integrally connected bottom plate 310 and side plate 311. The ventilation cover extension plate 2 is fixedly connected to the side plate 311, and the bottom plate 310 is connected to the top of the top flange 10. The main support 31 adopts a right-angle bending structure similar to angle iron. The bottom plate 310 can abut against the top flange 10, and the position of the side plate 311 facilitates connection with the ventilation cover extension plate 2. For the connection of the bottom plate 310 to the top flange 10, welding is preferred. Welding the main support 31 to the top flange 10 through the bottom plate 310 provides good conditions for the installation of the ventilation cover extension plate 2 on the fender 1 and its connection with the mounting bracket 3.

[0044] There are, of course, various technical solutions for the specific structural configuration of the main support 31 and the nacelle connecting frame 32; for example, various types of reinforcing structures such as cavities and bosses can be provided on the main support 31 and the nacelle connecting frame 32. However, to obtain a better technical effect, the following configuration is preferred. Specifically, combined with Figures 5 to 8 As shown, in this embodiment, as a preferred exemplary implementation among various feasible solutions, the side plate 311 of the main support 31 is formed with reinforcing ribs 314; preferably, reinforcing protrusions 313 can also be provided at the connection between the bottom plate 310 and the side plate 311. By providing some reinforcing ribs or reinforcing protrusions at appropriate positions on the main support 31, the overall structural stability of the support can be effectively enhanced.

[0045] Continue as Figure 4 , Figure 5 As shown, in this embodiment, as a preferred exemplary implementation among various feasible solutions, the top flange 10 is provided with a clearance notch 100 at the position where the mounting bracket 3 is located, and the bottom plate 310 is formed with a recessed portion 312 located in the clearance notch 100. At the same time, the recessed portion 312 is provided with a first connecting hole 316 for connecting the cabin connecting frame 32.

[0046] By setting a clearance notch 100 at the location where the mounting bracket 3 needs to be installed on the top flange 10, and correspondingly setting a recessed portion 312 on the bottom plate 310 of the main bracket 31, the recessed portion 312 can be confined within the clearance notch 100; then, a first connecting hole 316 is set on the recessed portion 312. When the main bracket 31 and the cabin connecting frame 32 are connected together by a connector passing through the first connecting hole 316, the limiting effect of the clearance notch 100 can further improve the stability of the entire mounting bracket 3 on the top flange 10.

[0047] like Figure 4 , Figure 8 As shown, when the bottom plate 310 exactly covers the position where the positioning hole 101 is set on the top flange 10, a through hole 315 can be opened on the bottom plate 310 so that the positioning post 213 on the reinforcing plate 21 can pass through the through hole 315 and be positioned and engaged with the positioning hole 101.

[0048] As a preferred exemplary implementation among various feasible solutions, the main support 31 and the cabin connecting frame 32 in this embodiment are fixed together by bolt pairs 5. The main support 31 and the cabin connecting frame 32 are located on the upper and lower sides of the top flange 10, respectively, and the top flange 10 is clamped between the main support 31 and the cabin connecting frame 32. Based on the above configuration, the bolt pairs 5 are inserted into the first connecting hole 316 and the second connecting hole 322 on the cabin connecting frame 32. Moreover, the part of the cabin connecting frame 32 where the second connecting hole 322 is provided has a protrusion 321 that protrudes into the clearance notch 100.

[0049] The main support 31 and the cabin connecting frame 32 are connected as one unit by bolt pair 5. At the same time, the main support 31 and the cabin connecting frame 32 are respectively set on the upper and lower sides of the top flange 10, which can effectively clamp the top flange 10 in the middle. With the limiting effect of the above-mentioned avoidance notch 100, as well as the sinking part 312 set on the main support 31 and the protrusion part 321 set on the cabin connecting frame 32, the various limiting, avoidance and reinforcement structures are tightly connected together by bolt pair 5 to form a stable connection, which can further improve the installation firmness of the mounting bracket 3 on the hospital gown.

[0050] In addition, the main bracket 31 of this embodiment is also provided with a nut 40, and the outer surface of the ventilation cover extension plate 2 is provided with a groove 200, and the bottom of the groove 200 is provided with a mounting hole 201. The ventilation cover extension plate 2 is screwed onto the nut 40 by a mounting bolt 4 passing through the mounting hole 201. On the main bracket 31, specifically on the side plate 311, the nut 40 is provided, which is screwed onto the mounting bolt 4 passing through the ventilation cover extension plate 2, so that the ventilation cover extension plate 2 can be reliably connected to the mounting bracket 3. By providing a groove 200 on the outer surface of the ventilation cover extension plate 2, the head of the mounting bolt 4 can be hidden in the groove 200, avoiding the appearance of a protruding structure on the outer surface of the vehicle body, which would affect the cleanliness of the vehicle body surface. Preferably, the nut 40 can be a thickened nut to improve the connection performance and its durability.

[0051] Given that the extension plate body 20 has a reinforcing plate 21 on its inner side, a clearance hole 210 should be provided on the reinforcing plate 21 to correspond to the sink 200, so that the protruding structure on the back of the sink 200 can extend into the clearance hole 210 to ensure a tight fit between the reinforcing plate 21 and the extension plate body 20.

[0052] In specific technical implementation or practical application, when it is necessary to install additional decorative parts on the ventilation cover extension plate 2, the aforementioned mounting bolts 4 are used to secure the additional decorative parts to the ventilation cover extension plate 2 and the mounting bracket 3. First, pass the mounting bolts 4 through the mounting holes on the additional decorative parts, then through the mounting holes 201 on the ventilation cover extension plate 2, and finally screw them into the nuts 40 on the main bracket 31. This fixes the additional decorative parts to the ventilation cover extension plate 2 and its internal mounting bracket 3, achieving the purpose of installing additional decorative parts on the ventilation cover extension plate 2. Due to the strong support of the mounting bracket 3, the ventilation cover extension plate 2 has good support capacity and can withstand the weight of the additional decorative parts, preventing the ventilation cover extension plate 2 from becoming loose, sagging, or damaged due to the installation of the additional decorative parts. There are, of course, a variety of technical solutions to choose from for the specific connection between the cabin connecting frame 32 and the cabin frame; for example, the connection method can be screwing or welding. It is preferred to use welding to pre-fix the cabin connecting frame 32 to the cabin frame, then assemble the fender 1 and the main bracket 31, and then install the ventilation cover extension plate 2 and the newly added decorative parts thereon.

[0053] Furthermore, in this embodiment, multiple mounting brackets 3 are spaced apart along the front-rear direction of the vehicle body on the top flange 10, and at least one mounting bracket 3 is provided at the rear end of the top flange 10. The multiple mounting brackets 3 spaced apart on the top flange 10 allow the engine compartment connecting frame 32 in each mounting bracket 3 to connect to the engine compartment frame on the side of the vehicle body. This creates a multi-point support structure between the vehicle body engine compartment frame and the ventilation cover extension plate 2, thereby enhancing the structural stability of the ventilation cover extension plate 2 and enabling it to withstand the installation of heavier new decorative parts.

[0054] Based on the above configuration, preferably, the nacelle connecting frame 32 located at the rear end of the top flange 10 has a plate facing the rear of the vehicle, and this plate is provided with a third connecting hole 323 for connecting the ventilation cover extension plate 2. The third connecting hole 323 is provided on the nacelle connecting frame 32 located at the rear end of the top flange 10, and correspondingly, a fourth connecting hole 215 can be provided at the rear end of the ventilation cover extension plate 2. Then, the rear end of the ventilation cover extension plate 2 can be fixed to the nacelle connecting frame 32 by connecting members passing through the fourth connecting hole 215 and the third connecting hole 323, thereby improving the installation stability of the rear end of the ventilation cover extension plate 2.

[0055] In the specific technical implementation or practical application process, the plate containing the third connecting hole 323 on the engine compartment connecting frame 32 can be arranged to face the rear. This plate is close to the rear A-pillar and other body structures. The rear end of the ventilation cover extension plate 2 and the engine compartment connecting frame 32 can be fixed to the A-pillar and other body structures by means of a link, so as to further enhance the connection and support effect between No. 2 and the body structure.

[0056] In summary, the ventilation cover extension plate mounting structure of this embodiment, by setting mounting brackets 3 on the top flange 10 of the fender 1, and the mounting brackets 3 being a pair of main brackets 31 and engine compartment connecting brackets 32, facilitates the connection between the engine compartment connecting brackets 32 and the engine compartment frame on the side of the vehicle body. By setting the main brackets 31 and the engine compartment connecting brackets 32 at the same position on the top flange 10 and fixing them together with connectors, the mounting brackets 3 can be firmly installed on the fender 1, and the connection between the mounting brackets 3 and the vehicle body can be guaranteed to be firm, thereby providing strong support for the installation of the ventilation cover extension plate 2 on the fender 1. When the ventilation cover extension plate 2 is connected to the main brackets 31, the support strength between the ventilation cover extension plate 2 and the vehicle body can be effectively improved, thereby providing favorable conditions for setting new decorative parts on the ventilation cover extension plate 2.

[0057] An embodiment of the second aspect of this application provides a vehicle having a ventilation cover extension plate mounting structure provided in Embodiment 1.

[0058] By installing the ventilation cover extension plate mounting structure of this application on the vehicle, and with the help of the mounting bracket 3 installed in the ventilation cover extension plate mounting structure, multi-point support and structural reinforcement can be formed between the ventilation cover extension plate 2, the fender 1, and the engine compartment frame located on the side of the vehicle body.

[0059] The mounting bracket 3 is composed of a pair of main brackets 31 and a nacelle connecting bracket 32, and is integrally fixed to the top flange 10 on the top of the fender 1 by bolt pairs 5; then the nacelle connecting bracket 32 ​​is integrally screwed to the nacelle frame on the side of the nacelle, providing an enhanced mounting structure that can both fix the ventilation cover extension plate 2 and support the newly added decorative parts that need to be installed later.

[0060] In the aforementioned enhanced mounting structure, both the main bracket 31 and the engine compartment connecting frame 32 preferably adopt a high-strength steel sheet metal bracket structure design, which can be connected to the fender 1 and the engine compartment frame, thereby significantly improving the load-bearing capacity of the mounting structure. This provides favorable conditions for adding new decorative parts to the ventilation cover extension plate 2 of the vehicle. It is compatible with the needs of later vehicle modifications, and additional decorative parts such as spotlights can be added to the ventilation cover extension plate 2 by mounting bolts 4.
