Description
Technical Field
[0001] The utility model relates to the technical field of automobile assembly, in particular to a supporting structure for a fully covering decorative cover of an engine compartment. Background Art
[0002] With the popularity of family cars, users not only have higher and higher requirements for the aesthetics of cars, but also pay more and more attention to NVH (noise, vibration and harshness) performance. There are various parts, multi-color wiring harnesses and controllers arranged in the car cabin, which has a poor visual effect. In order to improve the aesthetics of the cabin, the engine decorative cover is often used to cover the entire engine. However, if the structural design of the engine decorative cover is too strong, the weight and cost of the parts will increase significantly, and it will be difficult to install; if the structural design is weak, it will cause problems such as depression in the middle and vibration when driving at high speeds, and it is usually necessary to add supports to the cabin. The existing full-coverage engine decorative cover has a complex support frame structure, cumbersome manufacturing process, high cost, and it is easy to cause the full-coverage decorative cover to shake abnormally and produce abnormal noise. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a support structure for a fully covered decorative cover of an engine compartment, which can specifically adopt the following technical solutions:
[0004] The supporting structure for the full-covering decorative cover of the engine compartment described in the utility model comprises a first longitudinal beam and a second longitudinal beam, the front end of the first longitudinal beam is connected to the upper cross beam of the cabin radiator, and the rear end of the first longitudinal beam is arranged on the transverse flow channel body on the rear side of the cabin; the second longitudinal beam is arranged at an interval with the first longitudinal beam, the front end of the second longitudinal beam is connected to the upper cross beam of the cabin radiator, and the rear end of the second longitudinal beam is connected to the lower plate of the cabin front wall through an adapter bracket; the adapter bracket is composed of a first mounting section, an inclined section and a second mounting section connected in sequence, the first mounting section is arranged on the inner side of the lower plate of the cabin front wall by screws, the second mounting section is higher than the first mounting section and is arranged in the horizontal direction, a shock-absorbing pad is arranged between the second mounting section and the second longitudinal beam and is connected by bolts; the first longitudinal beam and the second longitudinal beam are also provided with a clamping piece adapted to the decorative cover.
[0005] The first longitudinal beam, the second longitudinal beam and the adapter bracket are all integrally formed structures, and are provided with a plurality of longitudinal reinforcing ribs and folded edge structures on both sides.
[0006] Two bolt mounting holes are arranged side by side on the second mounting section, and two opening holes are correspondingly arranged at the rear end of the second longitudinal beam. The shock-absorbing pad is a hollow columnar structure for passing bolts, and an annular mounting groove for clamping in the opening hole is opened in the middle of the shock-absorbing pad.
[0007] The supporting structure for the full-coverage decorative cover of the engine compartment provided by the utility model has a simple structure, low cost, is easy to manufacture and convenient to install. It fixes and supports the middle part of the full-coverage decorative cover through two supporting beams located on the front end radiator upper cross beam and the rear end front panel and the water flow channel body, and at the same time achieves the lightweight goal of the full-coverage decorative cover, optimizes the influence of vibration on the NVH performance of the automobile, and improves the overall performance of the automobile.

[0011] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0012] like Figure 1-3As shown, the supporting structure for the full-cover decorative cover of the engine compartment described in the utility model includes a first longitudinal beam 1, a second longitudinal beam 2 and an adapter bracket 3, all of which are integrally formed structures and are metal parts with folded edges 4 on both sides and multiple sections of longitudinal reinforcing ribs 5 in the middle. The front end of the first longitudinal beam 1 is overlapped on the upper cross beam 6 of the cabin radiator and connected by a fixing bolt; the rear end of the first longitudinal beam 1 is arranged on the lug 8 extending from the horizontal water flow channel body 7 at the rear side of the cabin and connected by two fixing bolts. The second longitudinal beam 2 is spaced apart from the first longitudinal beam 1, and the front end of the second longitudinal beam 2 is also overlapped on the upper cross beam 6 of the cabin radiator and connected by two fixing bolts arranged side by side; the rear end of the second longitudinal beam 2 is provided with two opening holes 21, and is connected to the lower panel 9 of the cabin front wall through the adapter bracket 3. Specifically, the adapter bracket 3 is composed of a first mounting section 31, an inclined section 32 and a second mounting section 33 connected in sequence. The first mounting section 31 is mounted on the inner side of the cabin front wall lower plate 9 by screws. The second mounting section 33 is located in front of the first mounting section 31 and is arranged horizontally higher than the first mounting section 31. Two bolt mounting holes 331 are arranged side by side on the second mounting section 33. The bolt mounting holes 331 correspond to the center of the opening hole 21 on the second longitudinal beam 2. A shock-absorbing pad 10 is arranged between the second mounting section 33 and the second longitudinal beam 2. The shock-absorbing pad 10 is a hollow columnar structure in which a bolt 11 can be passed through the center, and an annular mounting groove 101 for clamping in the opening hole 21 is opened in the middle of the shock-absorbing pad 10. When installing, first align the annular mounting groove 101 of the shock-absorbing pad 10 with the opening hole 21 and clamp it on the second longitudinal beam 2, then adjust the relative position of the second longitudinal beam 2 and the second mounting section 33, and then tighten the bolt in the center of the shock-absorbing pad 10 to fix the two together. The first longitudinal beam 1 and the second longitudinal beam 2 are both provided with a clamping piece 12 adapted to the decorative cover. When installing the decorative cover, it is only necessary to align the decorative cover with the clamping piece 12 according to a predetermined position and press to complete the installation.
[0013] The utility model has a simple structure, low cost, and is easy to manufacture and install. It has a stable support and light weight, which is conducive to the implementation of a lightweight solution for a full-coverage decorative cover. An energy-absorbing and shock-absorbing pad is arranged between the second longitudinal beam and the adapter bracket to avoid transmitting the vibration in the cabin to the cockpit, reduce the influence of vibration on NVH performance, and improve driving comfort. The bracket is connected to the full-coverage decorative cover with a decorative clip, and the operation is simple and easy.
[0014] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
