Description

Technical Field

[0001] This invention relates to the field of automobile design and manufacturing, and in particular to an integrated front engine compartment assembly and automobile. Background Technology

[0002] With the advancement of technology, electric vehicles have become an important means of transportation in people's daily lives. In traditional technology, the engine compartment module of a car is usually assembled from welded steel sheet metal parts, resulting in a relatively heavy overall weight of the vehicle. Traditional engine compartments often contain dozens of sheet metal parts, with numerous types and weld points, requiring more fixtures for auxiliary operation and subsequent processing. Furthermore, the structure of traditional engine compartments occupies a significant amount of space in the upper body, necessitating substantial modifications to the body when improvements to the upper body are needed. This results in low standardization, hindering model iteration and significantly increasing manufacturing and R&D costs.

[0003] In view of the above problems, this invention is proposed. Summary of the Invention

[0004] This invention provides an integrated front cabin assembly, which aims to solve the problems of high manufacturing and R&D costs caused by the complex structure, large number of parts, complicated assembly operations, and low degree of standardization of existing cabin modules.

[0005] This invention first provides an integrated front nacelle assembly, comprising:

[0006] The longitudinal beams include the left longitudinal beam and the right longitudinal beam, which are arranged symmetrically.

[0007] The torque box, including a left torque box and a right torque box, is screwed to the left and right longitudinal beams respectively; wherein...

[0008] The longitudinal beams and torsion box have threaded holes at the bottom. The left and right longitudinal beams are connected by an upper EDU crossbeam and a lower EDU crossbeam. The left and right torsion boxes are connected by an FDS lower crossbeam to the front bulkhead. The rear suspension mounting crossbeam is also connected at the bottom of the connection between the longitudinal beams and the torsion box. The front engine compartment assembly is connected by a single-sided operation.

[0009] In this design, the front nacelle assembly consists of longitudinal beams, a torsion box, a lower crossbeam of the front bulkhead, a rear suspension mounting crossbeam, an upper crossbeam of the EDU, and a lower crossbeam of the EDU. The longitudinal beams include a left longitudinal beam and a right longitudinal beam, which are screwed to the left and right torsion boxes in the torsion box, respectively. The longitudinal beams provide threaded holes for the connection of the torsion boxes. The longitudinal beams and torsion boxes are arranged symmetrically. The upper and lower crossbeams of the EDU are screwed between the left and right longitudinal beams. The longitudinal beams provide threaded holes for the connection of the upper and lower crossbeams of the EDU. The lower crossbeam of the front bulkhead is screwed between the left and right torsion boxes using a hot-melt self-tapping screw (FDS) connection. The bottom of the connection between the longitudinal beam and the torsion box is also screwed to the rear suspension mounting crossbeam. The longitudinal beam and the torsion box provide threaded holes for the connection of the rear suspension mounting crossbeam. All the above structural connections are completed through unilateral operation. By optimizing the structure of the front engine compartment assembly, assembly can be completed using electric wrenches and FDS benchtop equipment, greatly reducing the number of parts. This reduces the need for bulky installation equipment and shortens the production line, saving more production time. Furthermore, the integrated design of the front engine compartment assembly reduces the overall vehicle weight while increasing the versatility of the front engine compartment module, allowing it to adapt to more vehicle models and lowering R&D costs.

[0010] Optionally, a first fixing member is provided at the bottom of one inner end of the longitudinal beam. The first fixing member extends to the bottom of the longitudinal beam and has a threaded hole arranged on the side opposite to the torque box, which is used to suspend and install the crossbeam after the torque box is screwed in.

[0011] In this design, a first fixing member is provided at the bottom of one inner end of the left and right longitudinal beams. The first fixing member extends to the bottom of the longitudinal beam, so that the height of the rear suspension mounting crossbeam is lower than the height of the longitudinal beam, in order to adapt to the installation of the vehicle suspension structure. The first fixing member has a threaded hole on the side relative to the torque box. The rear suspension mounting crossbeam can be fixed on one side from the bottom of the front engine compartment assembly by bolts using the threaded hole of the first fixing member and the threaded hole at the bottom of the torque box.

[0012] Optionally, a second fastener is provided at the bottom of the other end of the inner side of the longitudinal beam. The second fastener has a threaded hole for screwing the lower crossbeam of the EDU. The second fastener is an arc-shaped part extending into the inner side of the longitudinal beam to adapt to the length of the lower crossbeam of the EDU.

[0013] In this design, a second fastener is provided at the bottom of the other end of the inner side of the longitudinal beam. The second fastener extends into the inner side of the longitudinal beam and is an arc-shaped component. By extending the second fastener to the bottom, it can be adapted to the length of the lower crossbeam of the EDU, while providing installation space for the automotive power module. The second fastener is provided with threaded holes, and the lower crossbeam of the EDU can be screwed between the left and right longitudinal beams on one side by bolts, which facilitates the installation of the lower crossbeam of the EDU.

[0014] Optionally, a third fastener is provided on the inner side of the longitudinal beam relative to the top of the second fastener. The third fastener has threaded holes for screwing the upper crossbeam of the EDU. The third fastener is a plate extending into the inner side of the longitudinal beam to adapt to the length of the upper crossbeam of the EDU.

[0015] In this design, the third fastener is arranged in the top space of the second fastener. The third fastener is a plate extending inward toward the longitudinal beam. The extension of the third fastener is less than that of the second fastener to accommodate the length of the upper beam of the EDU. The top of the third fastener has a threaded hole, through which the upper beam of the EDU can be fixed on one side from the top of the front cabin with bolts.

[0016] Optionally, the longitudinal beams may be fitted with cross-shaped internal reinforcement bars to increase their strength.

[0017] In this design, by designing intersecting internal reinforcement bars inside the longitudinal beams, the strength of the longitudinal beams can be increased while saving materials and reducing the weight of the forward engine compartment assembly, enabling the longitudinal beams to withstand greater loads.

[0018] Optionally, the torsion box is provided with multiple horizontal ribs and multiple vertical ribs, with the horizontal and vertical ribs distributed in a cross pattern to enhance the load-bearing capacity of the torsion box.

[0019] In this design, the torsion box is equipped with multiple horizontal and vertical ribs, which are distributed perpendicularly to each other. This improves the load-bearing capacity of the torsion box and reduces its deformation after a collision, thus protecting the car's floor structure.

[0020] Optionally, the lower crossbeam of the front bulkhead is equipped with internal reinforcing ribs to enhance its strength. One end of the lower crossbeam is also equipped with a floor connector for connecting to the vehicle floor.

[0021] In this design, the lower crossbeam of the front bulkhead is equipped with reinforcing ribs, which can reduce weight while increasing the strength of the lower crossbeam. One end of the lower crossbeam of the front bulkhead is equipped with a floor connection part to connect to the floor structure of the car.

[0022] Optionally, the top of the front engine compartment assembly is flat to increase the commonality of the front engine compartment assembly, and one end of the longitudinal beam is also provided with a front bumper beam connector for connecting the front bumper beam structure.

[0023] In this design, the top plane of the front engine compartment assembly is relatively flat, and the heights of the longitudinal beams, torsion box, and lower crossbeam of the front bulkhead are consistent. This allows the Z-axis space of the front engine compartment assembly to be used for storage or other functions, reducing the space occupied by the upper body. This adapts to different upper body structures and increases the versatility of the front engine compartment assembly. One end of the longitudinal beam is equipped with a crash beam connector to connect to the front crash beam structure of the car.

[0024] Optionally, the front nacelle assembly also includes bolts and FDS screws. The bolts are used to connect the longitudinal beams, torsion box, upper EDU crossbeam, lower EDU crossbeam, and rear suspension mounting crossbeam by threading the longitudinal beams. The FDS screws are used to connect the torsion box to the lower crossbeam of the front bulkhead.

[0025] In this solution, the front engine compartment assembly has two types of screw components: bolts and FDS screws, to accommodate the screwing requirements of the longitudinal beams, torsion box, lower crossbeam of the front bulkhead, rear suspension mounting crossbeam, upper crossbeam of the EDU, and lower crossbeam of the EDU within the front engine compartment assembly.

[0026] The present invention also provides an automobile including the aforementioned front engine compartment assembly.

[0027] In this design, the front engine compartment assembly is highly integrated. The front anti-collision beam structure of the vehicle is connected to one end of the longitudinal beam of the front engine compartment assembly, the floor structure is connected to one end of the lower crossbeam of the front bulkhead of the front engine compartment assembly, the suspension structure can be installed on the rear suspension mounting crossbeam, and the powertrain, steering structure, suspension structure and transmission structure can be installed on the longitudinal beam.

[0028] The integrated front engine compartment assembly and the beneficial effects of the present invention on the automobile include:

[0029] 1. By integrating the design of the front engine compartment assembly, the number of parts in the automotive front engine compartment module is greatly reduced, the weight of the engine compartment module is reduced, and the weight of the whole vehicle is reduced. The design of the internal structure of the front engine compartment assembly ensures the functionality of the engine compartment module while making installation more convenient, shortening the production line and thus reducing manufacturing costs.

[0030] 2. The front engine compartment assembly provided in this application can improve the universality of the engine compartment module of the car. The front engine compartment assembly does not need to occupy the layout space of the upper body and can be well adapted to different upper body models, reducing the car's R&D cost and facilitating the iteration of the car.

By optimizing the structure of the front engine compartment assembly 100, the various connection structures of the traditional engine compartment module are integrated into the front engine compartment assembly 100. The internal connection structure of the front engine compartment assembly 100 is optimized to solve the problems in the prior art, such as the large number of engine compartment module parts, the high weight of the whole vehicle, the large demand for auxiliary tools such as clamps during installation, the low degree of universality, and the high manufacturing cost and R&D cost during iteration.

[0055] Please refer to Figures 1-5 This is an optional solution in an embodiment of the present invention, wherein... Figure 1 The present invention, as illustrated, provides an integrated front nacelle assembly 100 with an overall structure comprising:

The upper crossbeam 5 and the lower crossbeam 6 of the EDU are screwed between the left longitudinal beam 1 and the right longitudinal beam 2. The lower crossbeam 3 of the front bulkhead is screwed between the left torsion box 8 and the right torsion box 7 using FDS. The rear suspension mounting crossbeam 4 is also screwed at the bottom of the connection between the longitudinal beam 10 and the torsion box 20. The screwing of the front engine compartment assembly 100 is completed by unilateral operation.

[0059] It should be noted that EDU stands for Electronic Control Drive Unit. The driving force of a car is controlled by the electronic control drive unit and then transmitted to the drive shaft of the car. The upper crossbeam 5 and the lower crossbeam 6 of the EDU are used to install the car's electronic control drive unit (EDU).

[0060] The following is a detailed explanation of each structure.

[0061] In this optional embodiment, the front nacelle assembly 100 consists of a longitudinal beam 10, a torque box 20, a front bulkhead lower crossbeam 3, a rear suspension mounting crossbeam 4, an EDU upper crossbeam 5, and an EDU lower crossbeam 6. The longitudinal beam 10 includes a left longitudinal beam 1 and a right longitudinal beam 2, which are screwed to the left torque box 8 and right torque box 7 in the torque box 20, respectively. The longitudinal beam 10 provides threaded holes 11 for connecting the torque box 20. The longitudinal beam 10 and the torque box 20 are symmetrically arranged, and an E is screwed between the left longitudinal beam 1 and the right longitudinal beam 2. The upper crossbeam 5 of the DU and the lower crossbeam 6 of the EDU, and the longitudinal beam 10 provide threaded holes 11 for connecting the upper crossbeam 5 and the lower crossbeam 6 of the EDU; the left torque box 8 and the right torque box 7 are connected to the lower crossbeam 3 of the front bulkhead using a hot-melt self-tapping screw (FDS) connection process; the bottom of the connection between the longitudinal beam 10 and the torque box 20 is also screwed to the rear suspension mounting crossbeam 4, and the longitudinal beam 10 and the torque box 20 provide threaded holes 11 for connecting the rear suspension mounting crossbeam 4; the screwing of the above structures is completed by unilateral operation. Through the structural optimization design of the front engine compartment assembly 100, assembly can be completed using an electric wrench and an FDS benchtop device, which greatly reduces the number of parts, reduces the need for excessively large equipment in terms of installation equipment, shortens the length of the production line, and saves more production time. At the same time, through the integrated design of the front engine compartment assembly 100, the weight of the whole vehicle is reduced while the versatility of the front engine compartment module is improved, so as to adapt to more models and reduce the development cost.

[0062] Furthermore, a first fixing member 41 is provided at the bottom of one inner end of the longitudinal beam 10. The first fixing member 41 extends to the bottom of the longitudinal beam 10 and has a threaded hole 11 arranged on the side opposite to the torque box 20, which is used to suspend and install the crossbeam 4 after the torque box 20 is screwed together.

[0063] In this embodiment, a first fixing member 41 is provided at the bottom of one inner end of the left longitudinal beam 1 and the right longitudinal beam 2. The first fixing member 41 extends to the bottom of the longitudinal beam 10, so that the height of the rear suspension mounting crossbeam 4 is lower than the height of the longitudinal beam 10, so as to adapt to the installation of the vehicle suspension structure. The first fixing member 41 has threads on the side relative to the torque box 20. The rear suspension mounting crossbeam 4 can be fixed on one side from the bottom of the front engine compartment assembly 100 by bolts 13 using the threaded hole 11 of the first fixing member 41 and the threaded hole 11 at the bottom of the torque box 20.

[0064] Furthermore, a second fastener 61 is provided at the bottom of the other end of the inner side of the longitudinal beam 10.

The second fixing member 61 extends into the inner side of the longitudinal beam 10 and is an arc-shaped member. By extending the second fixing member 61 to the bottom, it can be adapted to the length of the EDU lower crossbeam 6 and at the same time provide installation space for the automotive power module. The second fixing member 61 is provided with threaded holes 11. The EDU lower crossbeam 6 can be screwed between the left longitudinal beam 1 and the right longitudinal beam 2 on one side by bolts 13 to facilitate the installation of the EDU lower crossbeam 6.

[0067] In this embodiment, the third fastener 51 is arranged in the top space of the second fastener 61. The third fastener 51 is a plate extending into the longitudinal beam 10. The extension of the third fastener 51 is less than the extension of the second fastener 61 to adapt to the length of the upper crossbeam 5 of the EDU. The top of the third fastener 51 has a threaded hole 11. The upper crossbeam 5 of the EDU can be fixed on one side from the top side of the front cabin with bolts 13 through the threaded hole 11.

[0068] Furthermore, the longitudinal beam 10 is provided with cross-distributed internal reinforcement bars 15 to increase the strength of the longitudinal beam 10.

[0069] In this embodiment, by designing intersecting internal ribs 15 inside the longitudinal beam 10, the strength of the longitudinal beam 10 can be increased while saving materials and reducing the weight of the front engine compartment assembly 100, so that the longitudinal beam 10 can withstand greater loads. The longitudinal beam 10 is also provided with a transmission through hole 12 for the installation of the transmission structure of the automobile, wherein the transmission through hole 12 is a square hole.

[0070] Furthermore, the torsion box 20 is provided with three horizontal ribs 22 and three vertical ribs 21, which are distributed in a cross pattern to enhance the load-bearing capacity of the torsion box 20.

[0071] In this embodiment, the torque box 20 is provided with three horizontal ribs 22 and three vertical ribs 21. The horizontal ribs 22 and the vertical ribs 21 are distributed perpendicularly and cross each other to form a honeycomb structure, which can improve the load-bearing capacity of the torque box 20 and reduce the deformation of the torque box 20 after a collision, so as to protect the floor structure of the car.

[0072] Furthermore, the lower crossbeam 3 of the front bulkhead has internal reinforcing ribs 31 to enhance its strength, and one end of the lower crossbeam 3 of the front bulkhead also has a floor connecting part 32 for connecting to the car floor.

[0073] In this embodiment, the lower crossbeam 3 of the front bulkhead is provided with reinforcing ribs 31, which can reduce the weight while increasing the strength of the lower crossbeam 3 of the front bulkhead. One end of the lower crossbeam 3 of the front bulkhead is provided with a floor connecting part 32 to connect to the floor structure of the car.

[0075] In this embodiment, the top plane of the front engine compartment assembly 100 is relatively flat, and the heights of the longitudinal beam 10, the torsion box 20, and the lower crossbeam 3 of the front bulkhead are consistent. This allows the Z-axis space of the front engine compartment assembly 100 to be used for storage or other functions, reducing the space occupied on the upper body, so as to adapt to different upper body structures and increase the versatility of the front engine compartment assembly 100. One end of the longitudinal beam 10 is provided with a crash beam connector 40 to connect to the front crash beam structure of the car.
