Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a dash panel and a vehicle. Background Art

[0002] In existing vehicles, the dash panel's lower mounting plate is a U-shaped structure with an upward-facing opening. The dash panel's upper mounting plate extends forward, positioned above the opening but not completely enclosing it. This results in a weak dash panel structure. Consequently, in the event of a collision, the dash panel's ability to withstand external impact forces is limited, leading to severe deformation and a serious threat to occupant safety. Utility Model Content

[0003] The embodiment of the present application provides a front panel and a vehicle, which are intended to strengthen the structural strength of the front panel, improve the effectiveness of the front panel in resisting impact forces, and realize the multi-power layout requirements of the front body. The power switching of the front body can be achieved by simply replacing the crossbeam.

[0004] An embodiment of the present application provides a dash panel for a vehicle, the dash panel comprising:

[0005] A lower mounting plate, wherein the lower mounting plate is a U-shaped structure and has an opening;

[0006] An upper mounting plate covers the opening and is connected with the lower mounting plate to form a surrounding plate cavity.

[0007] In a possible design, the upper mounting plate is provided with an air inlet for communicating with the air conditioner, a mounting hole for installing a wiper, a mounting through hole for avoiding a wiring harness, and a first weight-reducing hole for reducing weight.

[0008] In a possible design, along the length direction of the vehicle, the front panel is provided with an installation groove for installing a sealing strip in a direction close to the front of the vehicle.

[0009] In a possible design, reinforcing ribs are provided on both sides of the upper mounting plate along the width direction of the vehicle;

[0010] The reinforcement ribs extend along the length direction of the vehicle.

[0011] An embodiment of the present application further provides a vehicle, comprising:

[0012] front hull;

[0013] A dash panel is mounted on the front vehicle body and is the dash panel described above.

[0014] In one possible design, the front body further includes a left A-pillar and a right A-pillar;

[0015] Along the width direction of the vehicle, the left A-pillar is connected to one end of the dash panel, and the right A-pillar is connected to the other end of the dash panel.

[0016] In a possible design, the front body further includes a front floor and a crossbeam;

[0017] The cross beam is connected to the front vehicle body to form a cross beam cavity.

[0018] In a possible design, the front vehicle body further includes a left longitudinal beam and a right longitudinal beam, and along the width direction of the vehicle, the left longitudinal beam and the right longitudinal beam are located on both sides of the cross beam;

[0019] The left A-pillar, the left longitudinal beam and one end of the crossbeam are connected in sequence, and the other end of the crossbeam, the right longitudinal beam and the right A-pillar are connected in sequence;

[0020] The front panel, the left A-pillar, the left longitudinal beam, the cross beam, the right longitudinal beam and the right A-pillar are connected to form an annular cavity structure.

[0021] In a possible design, the cross beam includes a first section, a second section, and a third section that are connected to each other. The first section is connected to the left longitudinal beam, and the third section is connected to the right longitudinal beam.

[0022] In a possible design, the crossbeam includes a first section, a second section, and a third section that are connected to each other, and the second section is recessed relative to the first section and the third section toward the front floor to avoid power components;

[0023] The first section is connected to the left longitudinal beam, and the third section is connected to the right longitudinal beam.

[0024] In this application, an upper mounting plate and a lower mounting plate are connected to form an approximately closed cavity, so that the closed cavity can effectively resist the impact force, enhance the structural strength of the front panel, and prevent the front panel from being severely deformed and invading the car compartment, thereby protecting the safety of the occupants.

[0025] Furthermore, this application moves the existing crossbeam on the dash panel down to connect with the front floor, creating a circular cavity structure that connects the dash panel, left A-pillar, left longitudinal beam, crossbeam, right longitudinal beam, and right A-pillar. This gives the front body a complete and continuous ring structure, improving its overall strength and torsional rigidity. Located in front of the vehicle compartment, this ring structure can better transmit force during head-on and side collisions, effectively resisting the impact of the front body, preventing severe deformation of the front body, and more effectively protecting occupants.

[0026] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0063] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0064] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0065] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0066] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0067] This embodiment provides a vehicle including a front body, which refers to a frame structure positioned at the front side in the longitudinal direction of the vehicle when forming an engine compartment. Figure 1 Shown is a schematic structural diagram of the front vehicle body 2. Figure 1 The front vehicle body 2 shown has X, Y, and Z directions. It should be noted that the vehicle is a roughly rectangular parallelepiped structure, and the X, Y, and Z directions in the figure represent the width, length, and height of the vehicle. The width direction X, length direction Y, and height direction Z are approximately perpendicular.

[0068] Please continue to refer to Figure 1 The front body 2 includes a front panel 1, which is a partition between the engine compartment and the vehicle compartment. The front panel 1 includes an upper mounting plate 12 and a lower mounting plate 11. For details, please refer to Figure 2 , Figure 2 It is a cross-sectional schematic diagram of the front panel 1. The lower mounting plate 11 is an approximately U-shaped structure with an opening 111. The upper mounting plate 12 is connected to the lower mounting plate 11 and can cover the opening 111, so that the upper mounting plate 12 and the lower mounting plate 11 are connected to form an approximately closed panel cavity 13.

[0069] In this embodiment, an upper mounting plate 12 is connected to a lower mounting plate 11 to form a nearly closed enclosure cavity 13, so that the closed enclosure cavity 13 can effectively resist the impact force, enhance the structural strength of the front enclosure 1, and prevent the front enclosure 1 from being severely deformed and intruding into the vehicle compartment, thereby protecting the safety of the occupants.

[0070] like Figure 3The figure shows a schematic structural diagram of the front body 2 from another perspective. The front body 2 includes an upper mounting plate 12, and the upper mounting plate 12 is provided with multiple mounting structures. Specifically, the upper mounting plate 12 is provided with an air inlet 121, a mounting hole 122, a mounting through-hole 123, and a first weight-reducing hole 124. Among them, the air inlet 121 is used to connect with the air-conditioning pipeline, the mounting hole 122 is used to install the wiper, the mounting through-hole 123 is used to avoid the wiring harness, and the first weight-reducing hole 124 is used to reduce the weight of the upper mounting plate 12. It should be noted that the first weight-reducing hole 124 is provided in an area on the upper mounting plate 12 where the force is relatively small, and has no effect on the structural strength of the front panel 1. Other mounting structures can also be provided on the upper mounting plate 12 without affecting the structural strength of the front panel 1, and this is not limited in this embodiment.

[0071] The upper mounting plate 12 and the lower mounting plate 11 can be fixed by welding to ensure the stability of the connection between the two.

[0072] Please continue to refer to Figure 3 Along the vehicle's width direction X, the upper mounting plate 12 is provided with reinforcing ribs 125 on both sides. The ribs 125 extend along the vehicle's length direction Y. By providing the reinforcing ribs 125 on the upper mounting plate 12 in this embodiment, the strength, rigidity, and service life of the upper mounting plate 12 are improved without increasing the thickness or weight of the upper mounting plate 12, thereby enhancing the strength and rigidity of the dash panel 1. Furthermore, the provision of the reinforcing ribs 125 on the upper mounting plate 12 facilitates the structural shaping of the upper mounting plate 12.

[0073] Furthermore, along the longitudinal direction Y of the vehicle, the front panel 1 is provided with an installation groove for installing a sealing strip near the front of the vehicle to prevent exhaust gas, high temperature and noise in the engine compartment from penetrating into the vehicle compartment.

[0074] Please continue to refer to Figure 1 The front vehicle body 2 includes a front panel 1 and an A-pillar. The A-pillar is used to support the roof and front windshield of the vehicle. The A-pillar has a cavity. When the vehicle is hit, the A-pillar has the function of protecting the front passengers.

[0075] Specifically, the A-pillar includes a left A-pillar 21 and a right A-pillar 22. Along the width direction X of the vehicle, the left A-pillar 21 is connected to one end of the front panel 1, and the right A-pillar 22 is connected to the other end of the front panel 1, so that the two ends of the panel cavity 13 of the front panel 1 are respectively connected to the cavity of the left A-pillar 21 and the cavity of the right A-pillar 22, so that the panel of the front panel 1, the cavity of the left A-pillar 21, and the cavity of the right A-pillar 22 form an approximate U shape, thereby increasing the structural strength of the front body 2 and improving the structural stability of the front body 2.

[0076] It should be noted that the connection between cavities means that adjacent cavities may be connected or may not be connected.

[0077] Figure 4 The figure shows a schematic diagram of the structure of the front body 2, viewed from the underside of the vehicle, in one embodiment. The front body 2 also includes a front floor 23 and a crossbeam 24. The front floor 23 supports the vehicle body. Along the vehicle's thickness direction Z, the crossbeam 24 connects to the bottom surface of the front floor 23 and forms a crossbeam cavity 241 with the front floor 23 to enhance the structural strength of the front floor 23.

[0078] Specifically, please refer to Figure 5 , Figure 5 Shown Figure 4 A cross-sectional schematic diagram of the mating position of the middle cross beam 24 and the front floor 23 shows that the cross section of the cross beam 24 along the width direction X of the vehicle is approximately in the shape of a "J", that is, the cross beam 24 has a cavity. After the cross beam 24 is connected to the front floor 23, the front floor 23 can block the cavity opening, so that the cross beam 24 forms a closed cross beam cavity 241, so as to strengthen the structural strength of the cross beam 24, thereby enhancing the strength and bearing capacity of the front floor 23.

[0079] The cross beam 24 and the front floor 23 may be connected by connecting members such as bolts and screws.

[0080] For further information, please refer to Figure 4 The front body 2 also includes a left longitudinal beam 25 and a right longitudinal beam 26. The left longitudinal beam 25 and the right longitudinal beam 26 are used to bear the weight of the vehicle. The left longitudinal beam 25 and the right longitudinal beam 26 both have cavities. When the vehicle collides, the left longitudinal beam 25 and the right longitudinal beam 26 can also absorb the collision energy to protect the safety of passengers.

[0081] The left A-pillar 21 is connected to the left longitudinal beam 25 at its end away from the dash panel 1, and the right A-pillar 22 is connected to the right longitudinal beam 26 at its end away from the dash panel 1. Along the vehicle width direction X, the left and right longitudinal beams 25 and 26 are located on either side of the crossbeam 24. The left longitudinal beam 25 is provided with a left support plate 251 extending toward the crossbeam 24 and connected to one end (the left end) of the crossbeam 24. The right longitudinal beam 26 is provided with a right support plate 261 extending toward the crossbeam 24 and connected to the other end (the right end) of the crossbeam 24.

[0082] Please refer to Figure 1 , the left A-pillar 21, the left longitudinal beam 25, the left support plate and one end of the crossbeam 24 are connected in sequence, and the other end of the crossbeam 24, the right support plate, the right longitudinal beam 26 and the right A-pillar 22 are connected in sequence. Figure 6 The dash panel 1, the left A-pillar 21, the left longitudinal beam 25, the cross beam 24, the right longitudinal beam 26 and the right A-pillar 22 are connected to form a ring.

[0083] In this embodiment, the original crossbeam 24 of the dash panel 1 is moved down to the bottom surface of the front floor 23. The ends of the crossbeam 24 are connected to the left and right longitudinal beams 25 and 26, respectively. This gives the front body 2 a complete ring structure, improving the overall strength and torsional rigidity of the front body 2. Located in front of the vehicle compartment, this ring structure can better transmit force during head-on and side collisions, effectively resisting the impact of the front body 2, preventing severe deformation of the front body 2, and more effectively protecting the safety of the occupants.

[0084] In addition, the front panel 1, the left A-pillar 21, the left longitudinal beam 25, the cross beam 24, the right longitudinal beam 26, and the right A-pillar 22 are all approximately closed cavity structures, that is, the front panel 1, the left A-pillar 21, the left longitudinal beam 25, the cross beam 24, the right longitudinal beam 26, and the right A-pillar 22 are connected to form an approximately closed and continuous annular cavity structure, further ensuring the safety and stability of the front body 2 structure.

[0085] It should be noted that the continuous annular cavity structure means that each piece is a cavity structure, and adjacent cavities may be connected or disconnected.

[0086] Among them, the left A-beam and the left longitudinal beam 25 are welded and fixed, the right A-beam and the right longitudinal beam 26 are welded and fixed, the cross beam 24 and the left support plate 251 of the left longitudinal beam 25 and the right support plate 261 of the right longitudinal beam 26 are all welded and fixed to ensure the connection strength of each part, thereby ensuring the stability of the formed annular cavity structure.

[0087] In some embodiments, cross beams 24 of different structures may be provided depending on the type of vehicle.

[0088] For example, the vehicle is a plug-in hybrid electric vehicle (PHEV). A plug-in hybrid electric vehicle is a new energy vehicle between a pure electric vehicle and a fuel vehicle. A plug-in hybrid electric vehicle has both the engine, transmission, drive system, oil circuit, and fuel tank of a traditional vehicle and the battery, motor, and control circuit of a pure electric vehicle. Figure 4 For plug-in hybrid vehicles, to accommodate the placement of components such as the engine and transmission, a portion of the front floor panel 23 is recessed toward the vehicle body (as viewed from the underside of the front floor panel 23), creating a mounting channel. Correspondingly, a portion of the cross member 24 is recessed toward the front floor panel 23 (as viewed from the underside of the front floor panel 23), creating mounting space. Furthermore, the cross member 24 matches the front floor panel 23 in shape, forming a cross member cavity 241 when connected.

[0089] Please refer to Figure 7 , Figure 7The figure shows a schematic diagram of the structure of the crossbeam 24 in one embodiment. In this embodiment, the crossbeam 24 comprises a first section 242, a second section 243, and a third section 244, which are connected. The second section 243 is located between the first section 242 and the third section 244. The first section 242 is connected to the left longitudinal beam 25, and the third section 244 is connected to the right longitudinal beam 26. Part of the second section 243 is recessed toward the front floor 23 relative to the first section 242 and the third section 244, ensuring the integrity of the annular structure of the front body 2 while providing clearance for components such as the engine and transmission.

[0090] To facilitate the formation of the structure of the second section 243 , the second section 243 may be composed of three welded parts, such as two symmetrical L-shaped sections and a straight section, wherein the two symmetrical L-shaped sections are connected on both sides of the straight section.

[0091] For example, if the vehicle is a pure electric vehicle (EV), which is completely powered by electricity, the layout of components such as the engine and transmission is not involved. Figure 8 , Figure 8 2 is a schematic structural diagram of another embodiment in the bottom direction of the front vehicle body 2. In this embodiment, the cross beam 24 can be set as a straight rod structure.

[0092] Specifically, if Figure 9 The figure shows a schematic structural diagram of the crossbeam 24 in another embodiment. The crossbeam 24 includes a first section 242, a second section 243 and a third section 244 that are connected to each other. The second section 243 is located between the first section 242 and the third section 244. The first section 242 is connected to the left longitudinal beam 25, and the third section 244 is connected to the right longitudinal beam 26.

[0093] The cross beam 24 is provided with a second weight-reducing hole 245 to reduce the weight of the cross beam 24 .

[0094] Therefore, to realize the multi-power layout requirement of the front vehicle body 2, the fuel\PHEV\EV only needs to replace the crossbeam 24 component to realize the power switching of the front vehicle body 2.

[0095] In some embodiments, Figure 7 In the embodiment shown, the first section 242 and the third section 244 of the cross beam 24 are Figure 9 In the illustrated embodiment, the first section 242 and third section 244 of the crossbeam 24 have the same structure. Specifically, depending on the vehicle model, the structure of the second section 243 of the crossbeam 24 can be replaced, while the first section 242 and third section 244 can be shared by both types of crossbeams 24. Therefore, the crossbeam 24 can be replaced according to different vehicle models, which helps improve the vehicle's multi-power compatibility, adapts to different types of vehicles, and allows for the sharing of body parts, thereby reducing costs.

[0096] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
