Description

Front strut assembly mounting structure and automobile Technical Field

[0001] This invention relates to automobile bodies, and more specifically to a front strut assembly mounting structure and an automobile. Background Technology

[0002] Existing front strut assemblies are generally fixed to the upper section of the front wheel arch using three M10 hexagonal flange nuts, resulting in a relatively simple installation structure and connection method. However, as users' demands for vehicle driving performance increase, the application of double wishbone front strut assemblies is becoming more and more common. Most models on the market now equipped with double wishbone front strut assemblies use aluminum alloy structures for their mounting. The advantage of this is a more compact front wheel arch space, which is beneficial for engine compartment layout. However, aluminum alloy raw materials are expensive, machining efficiency is low, and scrap parts are easily generated. Furthermore, aluminum alloy front wheel arches place higher demands on the production line; traditional welding production lines cannot meet the requirements of aluminum alloy front wheel arches, necessitating additional riveting equipment, leading to a relatively high cost for using aluminum alloy structures.

[0003] CN114475795A discloses a front strut mounting structure, including an upper section of the front wheel hump, a middle section of the front wheel hump, a heater pressure chamber plate, a heater pressure chamber plate reinforcement, and a fender mounting plate. The upper section of the front wheel hump includes a top wall, a first side wall, a second side wall, and a third side wall. A first overlapping edge is provided on the middle section of the front wheel hump, overlapping the first side wall. A second overlapping edge is provided on the heater pressure chamber plate, overlapping the second side wall. The heater pressure chamber plate reinforcement is provided with a third overlapping edge, overlapping the second side wall. The heater pressure chamber plate reinforcement overlaps with the third side wall. This invention has the advantages of simple structure, reliable performance, easy precision control, low cost, and strong practicality. Undoubtedly, the technical solution disclosed in the above patent document is a beneficial attempt in the relevant technical field, but this technical solution is not applicable to the installation of double wishbone front strut assemblies.

Detailed Implementation

[0027] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] As shown in Figures 1 and 2, a front strut assembly mounting structure in this embodiment includes an upper section 1 of the front wheel hub, a middle section 3 of the first front wheel hub, a middle section 2 of the second front wheel hub, and a double wishbone front and rear support connecting plate 11. The tops of the middle sections 3 and 2 are respectively connected to the front and rear parts of the upper section 1, and a first cavity 6 for accommodating the double wishbone front strut assembly is formed between the middle sections 3 and 2. The double wishbone front and rear support connecting plate 11 is disposed within the first cavity 6. The front strut assembly mounting structure is a sheet metal welded structure. Compared with aluminum alloy structures, the front strut assembly mounting structure in this embodiment is constructed by welding multiple separate components together, with each component processed separately. This structure has advantages such as simple structure, high sheet metal welding strength, low material cost, and ease of promotion and application.

[0029] This embodiment also includes a first reinforcing member 4 and a second reinforcing member 5; both the first reinforcing member 4 and the second reinforcing member 5 are disposed outside the first cavity 6. The first reinforcing member 4 and the middle section 3 of the first front wheel hub form a second cavity 12, and the second reinforcing member 5 and the middle section 2 of the second front wheel hub form a third cavity 15. The first reinforcing member 4 and the second reinforcing member 5 can further improve the strength and installation reliability of the front strut assembly mounting structure. Furthermore, the front strut assembly mounting structure has multiple cavities reasonably arranged at different positions, which can reduce the weight while ensuring strength and installation reliability, thus contributing to vehicle lightweighting.

[0030] This embodiment also includes two double wishbone mounting threaded pipes 10; one of the double wishbone mounting threaded pipes 10 is connected to both the first reinforcing member 4 and the middle section 3 of the first front wheel hub, and the other double wishbone mounting threaded pipe 10 is connected to both the second reinforcing member 5 and the middle section 2 of the second front wheel hub; bolt through holes are provided on the first reinforcing member 4, the middle section 3 of the first front wheel hub, the double wishbone front and rear support connecting plate 11, the second reinforcing member 5, and the middle section 2 of the second front wheel hub. During welding, the middle section 3 of the first front wheel hub, the middle section 2 of the second front wheel hub, the first reinforcing member 4, the second reinforcing member 5, and the two double wishbone mounting threaded pipes 10 are first welded together to form a first cavity 6 that runs through the vertical direction. Then, the upper section 1 of the front wheel hub and the middle section 11 of the double wishbone front and rear support are installed from bottom to top and welded to seal the upper part of the first cavity 6, thereby increasing the number of mounting points for the double wishbone front strut assembly. The front and rear sides of the double wishbone front strut assembly are connected to the first reinforcing member 4, the first front wheel hub mid-section 3, the double wishbone front and rear support connecting plate 11, the second reinforcing member 5, the second front wheel hub mid-section 2, and the two double wishbone mounting threaded tubes 10 via bolts. The upper part of the double wishbone front strut assembly is connected to the upper section 1 of the front wheel hub via bolts, ensuring the installation strength of the double wishbone front strut assembly. Furthermore, when the front strut assembly configured in the vehicle does not have double wishbones, the first reinforcing member 4, the double wishbone front and rear support connecting plate 11, the second reinforcing member 5, and the two double wishbone mounting threaded tubes 10 can be removed, leaving only the first front wheel hub mid-section 3 and the second front wheel hub mid-section 2. Therefore, regardless of whether the front strut assembly in the vehicle has double wishbones, the same set of molds and tooling can be used to process and assemble all components of the front strut assembly mounting structure, eliminating the need for new molds and tooling. This improves parts commonality and reduces production costs.

[0031] This embodiment also includes a rear reinforcement 16 for the upper section of the front wheel hump. The rear reinforcement 16 for the upper section of the front wheel hump includes a lower support leg and an upper mounting plate. The lower part of the lower support leg is connected to the upper section 1 of the front wheel hump, and the upper part of the lower support leg is connected to the front part of the upper mounting plate. The upper mounting plate extends rearward to form a support surface for supporting the heater pressure chamber plate 18, away from the upper section 1 of the front wheel hump. The support surface creates a large distance between the heater pressure chamber and the upper section 1 of the front wheel hump, thereby keeping the heater pressure chamber away from the connection between the upper section 1 of the front wheel hump and the double wishbone front strut assembly, preventing contamination of the mounting point of the double wishbone front strut assembly during the adhesive scraping process of the heater pressure chamber.

[0032] This embodiment also includes a fender mounting plate 17. The left side of the upper section of the front wheel hump rear reinforcement 16, the left side of the upper section of the front wheel hub 1, the left side of the middle section of the first front wheel hub 3, and the left side of the first reinforcement 4 are all connected to the fender mounting plate 17. The fender mounting plate 17 is connected to multiple components simultaneously, and the fender mounting plate 17 can also be connected to the fender, so that the left side of the upper section of the front wheel hump rear reinforcement 16, the left side of the upper section of the front wheel hub 1, the left side of the middle section of the first front wheel hub 3, and the left side of the first reinforcement 4 are connected together to form a reliable welded structure.

[0033] This embodiment also includes a central reinforcing member 7, the left side of which is connected to both the right side of the first reinforcing member 4 and the right side of the second reinforcing member 5. The central reinforcing member 7 has a central protrusion that forms a fourth cavity with the first reinforcing member 4 and the second reinforcing member 5. The central reinforcing member 7 can improve the connection strength between the first reinforcing member 4 and the second reinforcing member 5.

[0034] This embodiment also includes a rear connecting plate 14 for the front wheel hub. The lower part of the rear connecting plate 14 is connected to the lower part of the middle section 2 of the second front wheel hub. The upper part of the rear connecting plate 14 extends upward and is connected to the left side of the middle section 2 of the second front wheel hub. The rear part of the rear connecting plate 14 is provided with an overlapping surface for connection with the front wall panel welding assembly 19.

[0035] This embodiment also includes the front section 13 of the front wheel hub package located on the front side of the lower part of the first reinforcing member 4.

[0036] As shown in Figures 1-4, a car in this embodiment includes a front pillar assembly mounting structure, a heater pressure chamber plate 18, and a front wall panel welding assembly 19 disposed on the lower side of the heater pressure chamber plate 18. The heater pressure chamber plate 18 is connected to the upper mounting plate and the heater pressure chamber plate 18 is connected to the rear section connecting plate 14 of the front wheel hub.

[0037] This embodiment also includes an external reinforcing member 8 and an engine compartment side beam 9. The external reinforcing member 8 is disposed on the side of the central reinforcing member 7 away from the fourth cavity. The external reinforcing member 8, the central reinforcing member 7, the first reinforcing member 4, the second reinforcing member 5, and the front section 13 of the front wheel hub are all connected to the engine compartment side beam 9. The external reinforcing member 8 and the engine compartment side beam 9 can increase the connection strength of the aforementioned front strut assembly mounting structure.
