Description

Technical Field

[0001] The embodiments of the present application relate to the field of automobile technology, and in particular to a rear side panel structure and an automobile. Background Art

[0002] With the full popularization of cars in social families, the rapid development of social economy and the improvement of social living standards, people's requirements for cars are getting higher and higher, and have leaped to the requirements of comprehensive performance and quality. Automobile OEMs are paying more and more attention to improving automobile performance and quality, and the NVH performance (Noise, Vibration, Harshness, i.e., noise, vibration and sound roughness characteristics) of automobiles is a key indicator of automobile quality. This indicator can comprehensively reflect the comfort of the car. The better the NVH performance, the stronger the riding comfort felt by the passengers in the car.

[0003] In the prior art, the rear side panel of an automobile includes a C-pillar middle structure, and the C-pillar middle structure includes a rear side panel upper inner panel, a rear side panel lower inner panel and a rear side panel outer panel. The rear side panel upper inner panel and the rear side panel lower inner panel are connected to form a rear side panel inner panel assembly, and the rear side panel inner panel assembly and the rear side panel outer panel are both connected to a door sill beam, and the rear side panel inner panel assembly and the rear side panel outer panel form a cavity structure.

[0004] However, the noise generated by the rear wheels during driving is transmitted to the passenger compartment through the cavity structure surrounded by the rear side inner panel assembly and the rear side outer panel, resulting in loud noise inside the car, which greatly reduces riding comfort. Utility Model Content

[0005] In view of this, the embodiments of the present application provide a rear side panel structure and a car, which can reduce noise transmission, reduce noise inside the car, and improve the riding comfort in the passenger compartment.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a rear side panel structure, comprising:

[0011] The rear side panel structure provided in the embodiment of the present application has a partition assembly arranged between the first inner panel and the rear side panel outer panel and between the second inner panel and the rear side panel outer panel, but there is no partition assembly between the first inner panel and the rear side panel outer panel and between the second inner panel and the rear side panel outer panel of the existing automobile, thereby providing a new rear side panel structure. By adding the partition assembly between the first inner panel and the rear side panel outer panel and between the second inner panel and the rear side panel outer panel, the stiffness of the rear side panel structure is improved. Since the natural frequency of the rear side panel structure is related to the stiffness of the rear side panel structure, the natural frequency of the rear side panel structure can be changed by improving the stiffness of the rear side panel structure to avoid the natural frequency being within the frequency range of resonance with the human body, thereby improving the riding comfort in the passenger compartment. In addition, the partition assembly divides the cavity portion enclosed by the rear side panel outer panel and the rear side panel inner panel assembly into a first cavity and a second cavity, thereby reducing the volume of each cavity relative to the cavity structure in the prior art, thereby reducing noise transmission and thereby improving the riding comfort in the passenger compartment.

[0012] In a possible embodiment, the partition assembly includes a first partition and a second partition connected in the height direction of the vehicle, the first partition is connected between the first inner panel and the rear side outer panel, and the second partition is connected between the second inner panel and the rear side outer panel.

[0013] In a possible implementation manner, both ends of the first baffle are fixedly connected to the first inner panel and the rear side panel outer panel to improve the rigidity of the first baffle connected to the rear side panel outer panel and the first inner panel respectively.

[0014] In a possible implementation manner, portions of the first partition plate at both ends thereof are parallel to the first inner panel and the rear side panel outer panel.

[0015] In a possible embodiment, one end of the second baffle is fixedly connected to the second inner panel and the rear side outer panel respectively, and the other end of the second baffle is fixedly connected to the second inner panel to increase the stiffness of the second baffle connected to the rear side outer panel and the second inner panel respectively.

[0016] In a possible implementation, a portion where one end of the second partition is located is parallel to the second inner panel and the rear side panel outer panel, and a portion where the other end of the second partition is located is parallel to the second inner panel.

[0017] In a possible implementation manner, a cross-sectional area of ​​the first cavity gradually increases along an extension direction of the first cavity.

[0018] In a possible implementation, the first inner panel, the second inner panel, the rear side panel outer panel, the first partition plate, and the second partition plate are all integrally formed bent parts.

[0019] In a possible implementation manner, the second inner panel, the rear side panel outer panel and the partition assembly are respectively connected to the door sill beam of the automobile, so that the first cavity and the second cavity are closed to form a closed cavity.

[0020] In a second aspect, an embodiment of the present application provides a car, comprising the rear side panel structure as described above.

[0021] An automobile provided in an embodiment of the present application, since it includes the rear side panel structure provided in any one of the embodiments described above, has the same technical effect, that is, avoiding the natural frequency within the frequency range that resonates with the human body, reducing noise transmission, and thereby improving the riding comfort in the passenger compartment.

[0052] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the specific technical scheme of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0053] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0054] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0055] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0056] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] As described in the background art, the noise generated by the rear wheels of a car during driving is transmitted to the passenger compartment through the cavity structure formed by the rear side inner panel assembly and the rear side outer panel, resulting in a large noise inside the car, which greatly reduces the riding comfort. The inventors have found through research that the reason for this problem is that the cavity structure formed by the rear side inner panel assembly and the rear side outer panel is a large cavity, which makes the noise transmission strong, resulting in a large noise inside the car, and the natural frequency of the C-pillar middle structure of the rear side of the car is within the frequency range that resonates with the human body, which greatly reduces the riding comfort.

[0059] In order to solve the above problems, an embodiment of the present application provides a rear side panel structure and a car. By adding a partition assembly, the stiffness of the rear side panel structure can be improved, and the natural frequency of the rear side panel structure can be changed. The natural frequency is not within the frequency range that resonates with the human body. The partition assembly separates the cavity enclosed by the rear side panel outer panel and the rear side panel inner panel assembly into a first cavity and a second cavity. Each cavity is smaller, which reduces noise transmission, thereby improving the riding comfort in the passenger compartment.

[0060] The rear side panel structure and the automobile provided in the embodiments of the present application are described in detail below in conjunction with specific embodiments.

[0061] like Figure 1 As shown, the embodiment of the present application provides a rear side panel structure 100, which is applied to a car. Figures 2 to 5 As shown, the rear side panel structure 100 includes a rear side panel inner panel assembly 10, a rear side panel outer panel 20 and a partition panel assembly 30; the rear side panel inner panel assembly 10 includes a first inner panel 11 and a second inner panel 12 connected in the height direction of the vehicle (see Figure 3 As shown); the rear side panel outer panel 20 is respectively connected to the first inner panel 11 and the second inner panel 12 of the rear side panel inner panel assembly 10, and the rear side panel outer panel 20 and the rear side panel inner panel assembly 10 form a cavity portion; the partition assembly 30 is arranged in the cavity portion, and the partition assembly 30 is located between the first inner panel 11 and the rear side panel outer panel 20 and between the second inner panel 12 and the rear side panel outer panel 20, and the partition assembly 30 is configured to separate the cavity portion into a first cavity and a second cavity.

[0062] in, Figure 1 The direction H in the figure is the height direction of the car. The rear side panel structure 100 is located above the rear wheel 200 of the car (-H direction). The noise transmission path generated by the vibration of the rear wheel 200 during the driving of the car is first transmitted through the coil spring 300 and the shock absorber 400 on the chassis of the car, then transmitted to the rear side panel structure 100, and finally transmitted to the passenger compartment. It should be noted that the noise generated between the tire of the rear wheel 200 and the road surface during the driving of the car is also first transmitted through the coil spring 300 and the shock absorber 400 on the chassis of the car, and then transmitted to the rear side panel structure 100, and finally transmitted to the passenger compartment.

[0063] The first inner panel 11 is arranged in the front area of ​​the triangular window glass of the automobile. Figure 3 and Figure 4 As shown, the first inner panel 11 is located above the second inner panel 12, that is, the first inner panel 11 is located in the -H direction of the second inner panel 12. The second inner panel 12 and the first inner panel 11 can be connected by welding to form the rear side panel assembly 10.

[0064] The first inner plate 11 may be an integrally formed bent piece. Specifically, the first inner plate 11 is formed by stamping a steel plate. Figure 6 As shown, the first inner panel 11 includes a first inner panel section 111, a first inner panel section 2 112, a first inner panel section 3 113, a first inner panel section 4 114 and a first inner panel section 5 115 which are sequentially intersected and connected, and the first inner panel section 2 112, the first inner panel section 3 113 and the first inner panel section 4 114 form a recessed space 116. In this way, the strength of the first inner panel 11 can be improved, thereby providing a stable support for the body frame of the automobile.

[0065] The second inner plate 12 may be an integrally formed bent piece. Specifically, the second inner plate 12 is formed by stamping a steel plate. Figure 7 As shown, the second inner panel 12 includes a second inner panel segment 121, a second inner panel segment 122, a second inner panel segment 123, a second inner panel segment 124, and a second inner panel segment 125, which are sequentially intersected and connected. The second inner panel 12 is located above the rear wheel 200 of the vehicle, and the shape of the portion of the second inner panel 12 corresponding to the rear wheel 200 of the vehicle can be determined according to the runout envelope of the tire of the rear wheel 200 of the vehicle.

[0066] The rear side panel outer panel 20 can be an integrally formed bent part. The rear side panel outer panel 20 and the first inner panel 11 and the second inner panel 12 of the rear side panel inner panel assembly 10 form a cavity, and the upper part of the rear side panel outer panel 20 and the upper part of the rear side panel inner panel assembly 10 are respectively connected to the upper side rail 40 of the vehicle (see Figure 2 and Figure 3 The lower part of the rear side panel outer panel 20 and the lower part of the rear side panel inner panel assembly 10 are respectively connected to the door sill beam 50 (see Figure 2 and Figure 3 As shown in the figure), the cavity portion can be closed to form a closed cavity.

[0067] The partition assembly 30 is connected between the first inner panel 11 and the rear side outer panel 20, and between the second inner panel 12 and the rear side outer panel 20. The partition assembly 30 divides the cavity into a first cavity and a second cavity. The first cavity and the second cavity are not connected to each other.

[0068] like Figure 8 and Fig. 9As shown, the first cavity includes a first upper cavity 1011 and a first lower cavity 1012 which are connected to each other, and the second cavity includes a second upper cavity 1021 and a second lower cavity 1022 which are connected to each other. It can be understood that the partition assembly 30 separates the cavity enclosed by the rear side outer panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021, and the partition assembly 30 separates the cavity enclosed by the rear side outer panel 20 and the second inner panel 12 into a first lower cavity 1012 and a second lower cavity 1022.

[0069] The rear side panel structure 100 provided in the embodiment of the present application is provided with a partition assembly 30 to improve the stiffness of the rear side panel structure 100, change the natural frequency of the rear side panel structure 100, and avoid the natural frequency being within the frequency range of resonance with the human body; the partition assembly 30 separates the cavity part enclosed by the rear side panel outer panel 20 and the rear side panel inner panel assembly 10 into a first cavity 101 and a second cavity 102, and the volume of each cavity is small, thereby reducing noise transmission, reducing the noise inside the vehicle, and thereby improving the riding comfort in the passenger compartment.

[0070] It should be noted that the natural frequency of the rear side panel structure 100 can be increased or decreased, and no specific setting is made here, as long as the natural frequency is not within the frequency range that resonates with the human body.

[0071] In a possible implementation, Figure 8 and Fig. 9 As shown, the partition assembly 30 includes a first partition 31 and a second partition 32 connected in the height direction of the vehicle, the first partition 31 is connected between the first inner panel 11 and the rear side panel outer panel 20, and the second partition 32 is connected between the second inner panel 12 and the rear side panel outer panel 20. In this way, the first partition 31 can separate the cavity surrounded by the rear side panel outer panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021, and the second partition 32 can separate the cavity surrounded by the rear side panel outer panel 20 and the second inner panel 12 into a first lower cavity 1012 and a second lower cavity 1022.

[0072] The first partition plate 31 may be an integrally formed bending part. Specifically, the first partition plate 31 is formed by stamping a steel plate.

[0073] Both ends of the first partition 31 may be connected to the first inner panel 11 and the rear side panel 20, dividing the cavity surrounded by the rear side panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021; one end of the first partition 31 may be connected to the first inner panel 11 and the rear side panel 20 respectively, and the other end may be connected to the first inner panel 11 or the rear side panel 20, dividing the cavity surrounded by the rear side panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021; the two ends of the first partition 31 may also be connected only to the first inner panel 11 or the rear side panel 20. 0 connection, it can be understood that the two ends of the first partition plate 31 are only in contact with the first inner panel 11 or the rear side outer panel 20, dividing the cavity surrounded by the rear side outer panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021; the two ends of the first partition plate 31 can also be respectively connected to the first inner panel 11 and the rear side outer panel 20, it can be understood that one end of the first partition plate 31 is connected to the first inner panel 11, and the other end is connected to the rear side outer panel 20, dividing the cavity surrounded by the rear side outer panel 20 and the first inner panel 11 into a first upper cavity 1011 and a second upper cavity 1021.

[0074] Exemplarily, both ends of the first baffle 31 are fixedly connected to the first inner panel 11 and the rear side panel outer panel 20 to improve the rigidity of the first baffle 31 connected to the rear side panel outer panel 20 and the first inner panel 11, thereby improving the stability between the first baffle 31 and the rear side panel outer panel 20 and the first inner panel 11, and avoiding vibration between the first baffle 31 and the rear side panel outer panel 20 and the first inner panel 11. Specifically, Figure 6 , Figure 8 and Fig.10 As shown, the first partition 31 includes a first partition section 1 311, a first partition section 2 312 and a first partition section 313 which are sequentially intersected and connected. The first partition section 1 311 is respectively fixedly connected to the first inner panel section 111 of the first inner panel 11 and the rear side outer panel 20, and the first partition section 313 is respectively fixedly connected to the first inner panel section 5 115 of the first inner panel 11 and the rear side outer panel 20.

[0075] Both ends of the first baffle 31 may be welded to the first inner panel 11 and the rear side panel 20, or may be riveted to the first inner panel 11 and the rear side panel 20. For example, the first baffle section 311 of the first baffle 31 is welded to the first inner panel section 111 of the first inner panel 11 and the rear side panel 20, and the first baffle section 313 is welded to the first inner panel section 5 115 of the first inner panel 11 and the rear side panel 20.

The first baffle section 1 311 is parallel to the first inner panel section 111 of the first inner panel 11 and the rear side panel outer panel 20, and the first baffle section 313 is parallel to the first inner panel section 5 115 of the first inner panel 11 and the rear side panel outer panel 20. This arrangement facilitates the assembly of the first baffle 31 with the first inner panel 11 and the rear side panel outer panel 20.

[0077] The second partition plate 32 may be an integrally formed bending part. Specifically, the second partition plate 32 is formed by stamping a steel plate.

[0078] Both ends of the second partition plate 32 may be connected to the second inner panel 12 and the rear side panel outer panel 20, dividing the cavity surrounded by the rear side panel outer panel 20 and the second inner panel 12 into a first lower cavity 1012 and a second lower cavity 1022; one end of the second partition plate 32 may be connected to the second inner panel 12 and the rear side panel outer panel 20 respectively, and the other end may be connected to the second inner panel 12 or the rear side panel outer panel 20, dividing the cavity surrounded by the rear side panel outer panel 20 and the second inner panel 12 into a first lower cavity 1012 and a second lower cavity 1022; both ends of the second partition plate 32 may be connected only to the second inner panel 12 or the rear side panel outer panel 2 0 connection, it can be understood that the two ends of the second partition plate 32 are only in contact with the second inner plate 12 or the rear side outer plate 20, dividing the cavity surrounded by the rear side outer plate 20 and the second inner plate 12 into a first lower cavity 1012 and a second lower cavity 1022; the two ends of the second partition plate 32 can also be respectively connected to the second inner plate 12 and the rear side outer plate 20, it can be understood that one end of the second partition plate 32 is connected to the second inner plate 12, and the other end is connected to the rear side outer plate 20, dividing the cavity surrounded by the rear side outer plate 20 and the second inner plate 12 into a first lower cavity 1012 and a second lower cavity 1022.

[0079] For example, one end of the second baffle 32 is fixedly connected to the second inner panel 12 and the rear side outer panel 20, respectively, and the other end of the second baffle 32 is fixedly connected to the second inner panel 12, so as to improve the rigidity of the second baffle 32 connected to the rear side outer panel 20 and the second inner panel 12, respectively, thereby improving the stability between the second baffle 32 and the rear side outer panel 20 and the second inner panel 12, and avoiding vibration between the second baffle 32 and the rear side outer panel 20 and the second inner panel 12. Specifically, as Figure 7 , Fig. 9 and Fig.11 As shown, the second partition 32 includes a second partition section 1 321, a second partition section 2 322, a second partition section 323 and a second partition section 4 324 which are intersected and connected in sequence. The second partition section 1 321 is fixedly connected to the second inner plate section 2 122 of the second inner plate 12, and the second partition section 4 324 is respectively fixedly connected to the second inner plate section 5 125 of the second inner plate 12 and the rear side outer plate 20.

[0080] One end of the second partition plate 32 can be respectively welded to the second inner panel 12 and the rear side panel outer panel 20, and the other end of the second partition plate can be welded to the second inner panel 12; one end of the second partition plate 32 can also be respectively riveted to the second inner panel 12 and the rear side panel outer panel 20, and the other end of the second partition plate 32 can also be riveted to the second inner panel 12.

[0081] The portion where one end of the second partition plate 32 is located is the second partition plate section 4 324, and the portion where the other end is located is the second partition plate section 1 321. The second partition plate section 4 324 is parallel to the second inner plate section 5 125 of the second inner plate 12 and the rear side outer plate 20, respectively, and the second partition plate section 1 321 is parallel to the second inner plate section 2 122 of the second inner plate 12. This arrangement facilitates the assembly of the second partition plate 32 with the second inner plate 12 and the rear side outer plate 20.

[0082] The cross-sectional area of ​​the first cavity gradually increases along the extension direction of the first cavity. It can be understood that the cross-sectional area of ​​the first upper cavity 1011 is smaller than the cross-sectional area of ​​the first lower cavity 1012 .

[0083] The cross-sectional area of ​​the first cavity is perpendicular to the extension direction of the first cavity.
