Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body mounting structure and a vehicle. Background Technology

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0058] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0059] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0060] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0061] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0062] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0063] This application provides a vehicle body mounting structure, including multiple connecting structures 1, support beams 2, reinforcing beams 3, and first reinforcing members 4. The multiple connecting structures 1 are spaced apart. Support beams 2 are located below the connecting structures 1 and connected to each connecting structure 1. Reinforcing beams 3 are located below the support beams 2 and connected to the positions where the support beams 2 correspond to the positions of the connecting structures 1. The first reinforcing member 4 is located below the reinforcing beams 3 and connects the support beams 2 and the reinforcing beams 3. The lower parts of the support beams 2 and the first reinforcing member 4 are connected to the vehicle body. In use, the vehicle body mounting structure provided by this application provides that the support beams 2 are located below the connecting structures 1 and span across the multiple connecting structures 1, providing support to the lower part of the connecting structures 1. The support beams 2 are connected to the reinforcing beams 3 at the positions where they correspond to the connecting structures 1, thereby increasing the structural strength at the corresponding points where the support beams 2 and the connecting structures 1 are connected. This ensures sufficient connection strength between the support beams 2 and the connecting structures 1 without increasing the overall thickness of the support beams 2.

[0064] The first reinforcing member 4 is supported below the reinforcing beam 3. It can support the supporting beam 2 and the reinforcing beam 3 to further improve the strength of the supporting beam 2, and it can also be used to connect the supporting beam 2 and the reinforcing beam 3, thereby enhancing the connection strength between the supporting beam 2 and the reinforcing beam 3.

[0065] Therefore, the vehicle body mounting structure of this application embodiment can increase the structural strength of the support beam 2 without increasing the overall thickness of the support beam 2, avoid increasing the weight of the support beam 2, and help save the cost of the vehicle body mounting structure.

[0066] Furthermore, in this embodiment, the connection method between the reinforcing beam 3 and the supporting beam 2 is not limited, as long as the reinforcing beam 3 can support the supporting beam 2. Preferably, the reinforcing beam 3 is abutted against the bottom surface of the supporting beam 2. The reinforcing beam 3 can be connected to the bottom surface of the supporting beam 2 by welding, riveting, or bolting. For example, in this embodiment, the reinforcing beam 3 is welded to the bottom surface of the supporting beam 2.

[0067] The vehicle body mounting structure of this application embodiment can be compatible with the arrangement of multiple connecting structures 1, which can improve the performance of the entire vehicle body, play a multi-purpose role, and significantly improve the strength of the connecting structure 1 based on the original spatial boundaries.

[0068] The connection structure 1 refers to a pre-installed structure on the vehicle for mounting various parts and components. Furthermore, in this embodiment, the number of connection structures 1 is not limited. For example, each vehicle body mounting structure can reinforce two connection structures 1 and can be used to mount car seats or controllers, etc.

[0069] In some embodiments of this application, such as Figure 4As shown, the supporting beam 2 includes a beam body, a first flange 202, and a second flange 203. A recessed cavity 201 is formed on the lower side of the beam body, facing the connecting structure 1, and the reinforcing beam 3 is disposed within the cavity 201. The first flange 202 and the second flange 203 are formed on both sides of the beam body and extend in opposite directions. The first reinforcing member 4 includes a main body 401, a first connecting part 402, and a second connecting part 403. The main body 401 is connected to the reinforcing beam 3. The first connecting part 402 and the second connecting part 403 are respectively disposed on both sides of the main body 401. The first connecting part 402 is used to connect the first flange 202, and the second connecting part 403 is used to connect the second flange 203.

[0070] The support beam 2 has an "n"-shaped beam structure. The main body 401 of the first reinforcing member 4 is disposed in the cavity 201, which can divide the cavity 201 formed at the bottom of the support beam 2 into multiple reinforcing cavities spaced apart along the length of the support beam 2, thereby further improving the structural strength of the support beam 2. At the same time, the main body 401 of the first reinforcing member 4 can be used to connect the reinforcing beam 3. The first connecting part 402 and the second connecting part 403 can respectively connect the first flange 202 and the second flange 203 of the support beam 2.

[0071] The reinforcing beam 3 preferably extends from one end of the supporting beam 2 to the other end to reinforce the entire reinforcing cavity. As an alternative implementation, multiple reinforcing beams 3 may also be provided, with each reinforcing beam 3 located below a connecting structure 1.

[0072] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the first flange 202, the second flange 203 and the first reinforcing member 4 are connected to the panel 5 of the vehicle body.

[0073] With this configuration, the panel 5 can be used to close the cavity 201 at the bottom of the support beam 2, so as to form a closed reinforcing cavity between the support beam 2 and the panel 5, thereby improving the structural performance of the vehicle body mounting structure. The first reinforcing member 4 is at least partially disposed in the cavity 201, which can divide the reinforcing cavity into multiple cavities spaced apart along the length direction of the support beam 2. The multiple cavities are disposed below the connecting structure 1, which can fully reinforce the bottom of the connecting structure 1.

[0074] In some embodiments of this application, such as Figure 12 As shown, the first reinforcing member 4 also includes a third flange 404 and a fourth flange 405. The third flange 404 is located at the top of the main body 401 and is used to connect the reinforcing beam 3. The fourth flange 405 is located at the bottom of the main body 401, and the extension direction of the fourth flange 405 is opposite to the extension direction of the third flange 404. The fourth flange 405 is used to connect the panel 5.

[0075] By setting it up in this way, such as Figure 12 As shown, the cross-section of the first reinforcing member 4 can form a "Z" shape, further enhancing the structural strength of the vehicle body mounting structure. From bottom to top, the main body 401 of the first reinforcing member 4 is inclined away from the connecting structure 1, which can improve the resistance of the first reinforcing member 4 to lateral torsion, while increasing the volume of the reinforcing cavity formed by the first reinforcing member, panel 5, support beam 2 and reinforcing beam 3, and further enhancing the structural strength of the vehicle body mounting structure.

[0076] Furthermore, in this embodiment, the number of the first reinforcing member 4 is not limited; for example, such as... Figure 3 and Figure 4 As shown, each vehicle body mounting structure includes a pair of first reinforcing members 4. Along the length of the support beam 2, the two first reinforcing members 4 are respectively arranged on both sides of the connecting structure 1. The two first reinforcing members 4, the panel 5, the support beam 2 and the reinforcing beam 3 can jointly form a laterally extending reinforcing cavity. This laterally pressing reinforcing cavity can simultaneously cover multiple connecting structures 1 to achieve synchronous reinforcement of multiple connecting structures 1, and make the forces on multiple connecting structures 1 coordinated and complementary.

[0077] In some embodiments of this application, such as Figure 5 As shown, the vehicle body mounting structure also includes a second reinforcing member 6. The second reinforcing member 6 covers the top of the connecting structure 1 and connects the two connecting structures 1. The second reinforcing member 6 strengthens the upper part of the connecting structure 1 by covering it. Since the second reinforcing member 6 connects the two connecting structures 1, its placement increases the force transmission path between the connecting structures 1. When either of the two connecting structures 1 is subjected to force, that connecting structure 1 can transmit the force it bears to the other connecting structure 1 through the second reinforcing member 6, thereby coordinating the forces on the two connecting structures 1 and improving the overall performance of the vehicle body mounting structure.

[0078] In this application embodiment, the specific structure of the second reinforcing structure is not limited. For example, such as Figure 8 and Figure 9 As shown, the second reinforcing member 6 is a beam structure.

[0079] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the vehicle body mounting structure also includes a mounting component 7 and a mounting nut 8. The top of the mounting component 7 is connected to the second reinforcing member 6, and the bottom is connected to the support beam 2, forming a mounting cavity 701 between the mounting component 7 and the support beam 2. Figure 10 and Figure 11As shown, the mounting nut 8 is located in the mounting cavity 701 and connected to the mounting member 7. The second reinforcing member 6 and the mounting member 7 are respectively provided with a first mounting hole 601 and a second mounting hole 702. The first mounting hole 601 and the second mounting hole 702 are coaxially arranged with the mounting nut 8.

[0080] Mounting member 7 and mounting nut 8 can form a connecting structure 1. An operator can use bolts to sequentially pass through the component and mounting nut 8 to mount the component to the vehicle body via the connecting structure 1. Mounting nut 8 is preferably, but not limited to, connected to mounting member 7 by means of riveting, snap-fitting, or bolting. Alternatively, mounting nut 8 is welded to mounting member 7.

[0081] The second reinforcing member 6 is preferably, but not limited to, connected to the mounting member 7 by means of bolting, welding or riveting. For example, the second reinforcing member 6 is bolted to the mounting member 7.

[0082] In this embodiment of the application, the specific structure of the mounting component 7 is not limited. For example, as shown in the following example... Figure 13 As shown, the mounting component 7 is a box-shaped structure with an open bottom, and the inner cavity of the box-shaped structure forms a mounting cavity 701. A connecting edge 703 is formed at the bottom of the box-shaped structure, which is used for welding connection with the support beam 2.

[0083] In some embodiments of this application, the mounting nut 8 includes a nut plate 801 and a support nut 802. The nut plate 801 is connected to the mounting member 7. The support nut 802 is connected below the nut plate 801 and is coaxially arranged with the nut plate 801. A support ring edge 8021 is formed on the outer periphery of the support nut 802, and the support ring edge 8021 is connected to the nut plate 801.

[0084] The nut plate 801 can be used to cover the entire area of ​​the connecting structure 1, and the support nut 802 can mate with the nut plate 801 and be reliably connected to the external bolts.

[0085] In some embodiments of this application, the vehicle body mounting structure further includes a third reinforcing member 9 and a fourth reinforcing member 10, respectively connected to both ends of the support beam 2. The extending directions of the third reinforcing member 9 and the fourth reinforcing member 10 both form an angle with the extending direction of the support beam 2. The support beam 2, the third reinforcing member 9, and the fourth reinforcing member 10 can together form an "I"-shaped frame structure, which can further enhance the performance of the vehicle body mounting structure.

[0086] In some embodiments of this application, a protrusion 204 is formed on the support beam 2, protruding toward the connecting structure 1, and a plurality of connecting structures 1 are disposed on the protrusion 204.

[0087] The protrusion 204 increases the volume of the reinforcing cavity formed by the first reinforcing member 4, the support beam 2, and the panel 5, and further enhances the structural strength of the vehicle body mounting structure. Preferably, the support beams 2 on both sides of the protrusion 204 are recessed downward to form grooves, which can serve as reinforcing ribs and further enhance the structural strength of the support beams 2.

[0088] According to an embodiment of this application, another aspect provides a vehicle, including a body and a body mounting structure provided in the first aspect of this utility model, the body mounting structure being disposed within the body.

[0089] The vehicle of the second aspect of this utility model includes or uses the body mounting structure of the first aspect of this utility model, and thus has the beneficial effect of increasing the structural strength of the support beam 2 without excessively increasing the weight of the support beam 2, which helps to save the cost of the body mounting structure.

[0090] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0091] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
