[0054] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0055] See also Figures 1 to 18 This embodiment provides a storage rack assembly, including a reinforcing beam assembly 1 and a storage plate assembly 2, wherein the reinforcing beam assembly 1 includes a front reinforcing beam 11, a rear reinforcing beam 12, a left reinforcing beam 13 and a right reinforcing beam 14; the front reinforcing beam 11, the rear reinforcing beam 12, the left reinforcing beam 13 and the right reinforcing beam 14 are connected to form a frame structure, such as Figure 1 As shown, the reinforcing beam assembly 1 forms a stable frame structure as a whole, preventing the reinforcing beam assembly 1 from twisting in the front-to-back direction or the left-to-right direction. The storage plate assembly 2 is connected to the reinforcing beam assembly 1, and the reinforcing beam assembly 1 connects and supports the storage plate assembly 2, thereby improving the torsional rigidity of the entire storage rack assembly.

[0056] In some embodiments of this application, please refer to Figure 1 The reinforcement beam assembly 1 is a bilaterally symmetrical structure, which can make the force distribution of the reinforcement beam assembly 1 uniform and realize uniform force transmission to the body side assembly 7 on the left and right sides of the body. Figure 5 Specifically, the left reinforcing beam 13 and the right reinforcing beam 14 are symmetrically arranged on both sides of the front reinforcing beam 11 or the rear reinforcing beam 12 to form a symmetrical frame structure, which can ensure that the reinforcement beam assembly 1 is structurally stable and that the forces on both sides of the reinforcement beam assembly 1 are uniform.

[0057] It should be noted that the frame structure can be a rectangular, trapezoidal or tic-tac-toe structure, so that the reinforcement beam assembly 1 forms a frame structure with stable structure and high strength, which is conducive to improving the torsional rigidity of the storage rack assembly. As a specific embodiment of the present application, the front and rear ends of the left reinforcement beam 13 are respectively fixedly connected to the front reinforcement beam 11 and the rear reinforcement beam 12, and the front and rear ends of the right reinforcement beam 14 are respectively fixedly connected to the front reinforcement beam 11 and the rear reinforcement beam 12, so that the reinforcement beam assembly 1 has a square-shaped (i.e. rectangular) frame structure.

[0058] In some embodiments of this application, please refer to Figure 2 The storage board assembly 2 includes a storage board middle plate 21, which is arranged in the middle area of ​​the storage rack assembly and has the main function of placing items. The storage board middle plate 21 is connected to the front reinforcement beam 11, the rear reinforcement beam 12, the left reinforcement beam 13 and the right reinforcement beam 14 on all sides, which can improve the structural strength of the storage board middle plate 21 and facilitate the improvement of the load-bearing capacity of the storage board middle plate 21.

[0059] Specifically, the front end of the storage plate middle plate 21 is arranged above the front reinforcing beam 11, the left and right sides of the storage plate middle plate 21 are respectively connected to the left reinforcing beam 13 and the right reinforcing beam 14, and the rear end of the storage plate middle plate 21 is fixedly connected to the rear reinforcing beam 12. Figure 3 and Figure 4 As shown, a plurality of reinforcing beams can be used to form a stable connection and support around the middle plate 21 of the cargo plate.

[0060] In some embodiments of this application, please refer to Figure 2 The storage board assembly 2 also includes storage board side panels arranged on both sides of the storage board middle plate 21. The two ends of the storage board side panels in the front and rear directions are respectively connected to the front reinforcing beam 11 and the rear reinforcing beam 12, and one side of the storage board side panels in the left and right directions is connected to the left reinforcing beam 13 or the right reinforcing beam 14, so that the storage board side panels have good structural strength, so as to increase the total area of ​​the storage board assembly 2 through the storage board side panels.

[0061] Specifically, two storage board side panels are provided on the left and right sides of the storage board middle panel 21, namely a first storage board side panel 22 and a second storage board side panel 23. Figure 2 shown.

[0062] In some embodiments of this application, please refer to Figure 2 The storage plate assembly 2 further includes a storage plate left front plate 24 and a storage plate right front plate 25, which are arranged on both sides of the storage plate middle plate 21 and can provide connection points for subsequent welding of the storage plate middle plate 21. The storage plate left front plate 24 and the storage plate right front plate 25 are both connected to the front reinforcing beam 11 to enhance the structural strength of the storage plate left front plate 24 and the storage plate right front plate 25.

[0063] It should be noted that, since the left front plate 24 and the right front plate 25 of the storage board are relatively small in size and are located on both sides of the front end of the storage board assembly 2, fewer items are placed on them, and the requirements for their surface flatness and load-bearing capacity are relatively small. In some embodiments of the present application, the left front plate 24 and the right front plate 25 of the storage board have a hollow structure, which can be used to reduce weight or realize the installation of parts at the rear of the vehicle body, such as Figure 2 shown.

[0064] In the above embodiment, in order to ensure the lightweight of the storage rack assembly, the storage plate assembly 2 is made of thin steel plates, and transverse and longitudinal reinforcing beams are arranged on the storage plate assembly 2 to ensure the overall rigidity of the storage rack assembly on the basis of lightweight.

[0065] As users' requirements for riding experience continue to increase, the roof form of traditional cars cannot meet the daily needs of all passengers in the car. More and more vehicles are equipped with panoramic skylights 3 on the top of the car body, which can realize the opening and closing of the roof, such as Figure 6 and Figure 7 As shown. The opening size of the skylight can be twice that of conventional models, so as to achieve the effect of full opening above the heads of front and rear passengers, and both front and rear passengers can have the ultimate upper space at the same time. Since the installation of the panoramic skylight 3 has a certain impact on the vehicle body structure, it is necessary to consider improving the structural rigidity of the rear part of the vehicle body through the storage rack assembly, so as to realize the layout of the panoramic skylight 3 on the vehicle body.

[0066] See also Figures 1 to 18 The embodiment of the present application also provides a vehicle body rear structure, including the storage rack assembly described in the above embodiment, and also including a canopy frame 31. The storage rack assembly is connected to the canopy frame 31 and is used to connect with the rear of the canopy frame 31 to form a vehicle body rear frame 313. Since the storage rack assembly has good torsional stiffness, after the storage rack assembly is connected to the canopy frame 31, it is beneficial to improve the torsional stiffness of the rear of the panoramic canopy 3.

[0067] In some embodiments of this application, please refer to Figure 8 , Fig. 9 and Fig.10 The rear reinforcing beam 12 has a plurality of mounting portions 121 , and the canopy frame 31 is connected to the plurality of mounting portions 121 . The rear end of the canopy frame 31 is fixed by connecting the rear reinforcing beam 12 to the canopy frame 31 .

[0068] Specifically, along the width direction of the vehicle body, the rear reinforcing beam 12 has a plurality of mounting portions 121, and the mounting portions 121 have connection holes for inserting connecting members (such as bolts, etc.). The rear frame 313 of the canopy frame 31 is provided with a plurality of first connecting portions 311, and the first connecting portions 311 are arranged one by one with the mounting portions 121, and are connected by bolts and fixing nuts 9, which can provide the canopy frame 31 with a plurality of mounting points with high structural strength, such as Fig.12 The bottom of the rear reinforcing beam 12 has a first nut through hole, which is convenient for installing the fixing nut 9 from the bottom of the rear reinforcing beam 12.

[0069] In some embodiments of this application, please refer to Fig.12The rear reinforcing beam 12 also has a supporting portion 122, which can be used to support the rear frame 313 at the rear end of the canopy frame 31. Below the supporting portion 122 is a cavity structure formed by the rear reinforcing beam 12, which can provide stable support for the rear of the canopy frame 31. The outer surface of the rear frame 313 can be bonded to the supporting portion 122 through an adhesive layer. Specifically, the rear frame 313 and the supporting portion 122 are fixedly connected by glass glue.

[0070] In some embodiments of this application, please refer to Fig. 9 , Fig.10 , Fig.11 and Fig.13 The left reinforcing beam 13 and the right reinforcing beam 14 are both provided with mounting brackets 4, and the canopy frame 31 is connected to the mounting brackets 4. The mounting brackets 4 are arranged on the left reinforcing beam 13 or the right reinforcing beam 14, which can provide a stable support point with high structural strength for the mounting brackets 4. The mounting brackets 4 have a certain height, which is convenient for connection with the inclined longitudinal beams on both sides of the canopy frame 31.

[0071] Specifically, the two sides of the canopy frame 31 have second connecting parts 312, and the second connecting parts 312 are arranged one by one with the mounting brackets 4, and are connected by bolts and fixing nuts 9, such as Fig.13 The storage plate middle plate 21, the left reinforcing beam 13 and the right reinforcing beam 14 are all provided with second nut through holes, so as to facilitate the fixing nut 9 to be installed into the bottom of the mounting bracket 4 from the bottom of the storage rack assembly.

[0072] In some embodiments of this application, please refer to Fig.14 and Fig.15 The mounting bracket 4 includes a top plate 41, a support plate 42 and a reinforcing plate 43. The top plate 41 has a mounting hole 411, which can be used to insert a connector to achieve a fixed connection between the second connecting portion 312 and the mounting bracket 4. Multiple support plates 42 are connected to the top plate 41 at an angle, and the support plates 42 raise the height of the top plate 41 while forming a stable support for the top plate 41. The angle between the top plate 41 and the support plates 42 can be 90°-120°. In order to reduce the space occupancy rate of the mounting bracket 4, it is preferred that the angle between the support plates 42 and the top plate 41 is 90°. Fig.13 and Fig.14 The reinforcing plate 43 is connected between the two support plates 42, and can be used to enhance the overall structural strength of the mounting bracket 4, so as to form a stable support for the canopy frame 31 when connected to the canopy frame 31. There are more than two support plates 42, which are sequentially arranged along the circumference of the top plate 41.

[0073] In some preferred embodiments of the present application, the mounting bracket 4 includes three L-shaped support plates 42, the bottom of the support plate 42 is connected to the left reinforcing beam 13 or the right reinforcing beam 14, and two reinforcing plates 43 are respectively connected to two adjacent support plates 42 to form a mounting bracket 4 with a bottom opening, such as Fig.14 The reinforcing plate 43 and the supporting plate 42 connected thereto are an integrated bending structure, which facilitates the manufacture of the mounting bracket 4. The expanded view of the mounting bracket 4 is shown in FIG. Fig.15 As shown, the two support plates 42 on both sides are respectively connected with the two reinforcing plates 43 to form an integrated structure, which can be produced by a set of stamping dies for blanking, punching, forming and bending. After forming, the reinforcing plates 43 on both sides and the middle support plate 42 overlap each other and can be spot welded directly to connect the three support plates 42 into one, forming a self-welding structure similar to a box, which can provide sufficient rigidity for the installation of the canopy.

[0074] It should be noted that the mounting bracket 4 in the present application has good parts molding and simple process, and can be processed with only one set of molds. The mounting brackets 4 on the left and right sides can share the stamping mold, and there is no need to develop welding fixtures during the production process, which is more cost-effective and has high production efficiency.

[0075] In the above embodiment, since the skylight drive component 33 in the panoramic skylight 3 is often arranged at the rear of the skylight frame 31, after the rear of the skylight frame 31 is fixedly connected to the storage rack assembly through the first connecting part 311 and the second connecting part 312, it is not convenient to inspect and repair the skylight drive component 33 and other components.

[0076] In order to solve the above problems, in some embodiments of the present application, please refer to Fig.16 The storage plate assembly 2 is provided with a canopy inspection port 211, and the operator can inspect the components at the rear of the panoramic canopy 3 through the canopy inspection port 211. Specifically, the canopy inspection port 211 is arranged at the rear end of the storage plate middle plate 21, and the canopy inspection port 211 is arranged opposite to the canopy drive member 33, so that the maintenance tool can be extended into the rear of the panoramic canopy 3 from the canopy inspection port 211. The canopy drive member 33 includes electronic components such as the motor system of the sunroof system. During use, the operator can perform daily inspections through the canopy inspection port 211. If parts need to be replaced, the motor and other components can be removed and replaced through the canopy inspection port 211.

[0077] In some embodiments of the present application, the panoramic skylight 3 also includes a drainage assembly 32 arranged on the left and right sides. The drainage assembly 32 is arranged through the skylight frame 31. In order to prevent the water discharged by the drainage assembly 32 from remaining on the storage rack assembly, a through hole 231 is provided on the storage plate assembly 2. The drainage assembly 32 is inserted into the through hole 231, so that the water in the drainage assembly 32 can be discharged smoothly.

[0078] Since the drainage assembly 32 is arranged on both sides of the canopy frame 31, it is preferred to open a through hole 231 on the first storage board side plate 22 and the second storage board side plate 23, so as to reduce the pipe length of the drainage assembly 32 and reduce the influence of the drainage assembly 32 and the through hole 231 on the storage space. Fig.16 and Fig.17 shown.

[0079] In some embodiments of this application, please refer to Fig.18 The rear structure of the vehicle body also includes a first side reinforcement beam assembly 5 and a second side reinforcement beam assembly 6. The storage rack assembly is respectively connected to the first side reinforcement beam assembly 5 and the second side reinforcement beam assembly 6, which can form two force transmission paths on a single side of the rear of the vehicle body (i.e., the left side of the vehicle body or the right side of the vehicle body).

[0080] One of the first side enclosure reinforcing beam assembly 5 and the second side enclosure reinforcing beam assembly 6 extends in the vertical direction, and the other extends obliquely upward toward the storage rack assembly, thereby forming two force transmission paths with different force transmission directions.

[0081] Specifically, the first side reinforcement beam assembly 5 is a front reinforcement beam system on the side wheel hub package, extending obliquely upward toward the storage rack assembly, and the second side reinforcement beam assembly 6 is a rear reinforcement beam system on the side wheel hub package, extending in the vertical direction. The storage plate assembly is connected to the wheel hub package assembly 71 in the body side assembly 7 through the first side reinforcement beam assembly 5 and the second side reinforcement beam assembly 6, and then connected to the entire lower body assembly 8 through four force transmission paths, so that the entire rear body structure is effectively connected and the structure is stable, the torsional stiffness of the rear body is improved, and the generation of abnormal noise is avoided; at the same time, the local mode of the rear body structure is improved to avoid abnormal noise caused by resonance with the body.

[0082] The embodiment of the present application also provides a car, comprising the rear body structure described in the above embodiment. A panoramic skylight 3 is provided on the roof of the car, and the panoramic skylight 3 is fixedly connected to the body side assembly 7.

[0083] The storage plate assembly of the present application includes a reinforcement beam assembly 1 in a frame structure, which has a stable structure and improves the torsional stiffness of the storage rack assembly. The storage rack assembly itself establishes stable characteristics, and its strength and stiffness meet the requirements. By connecting the storage plate assembly to the rear of the skylight frame 31, the torsional stiffness of the vehicle body structure is improved, and then the strength and stiffness of the entire rear of the vehicle body are improved, which can meet the structural strength and stiffness requirements of the vehicle body itself, meet the installation and maintenance requirements of the new openable panoramic skylight 3, and facilitate the setting of the panoramic skylight 3, thereby providing users with a new top full opening experience and meeting the driving experience requirements of users in different scenarios. The storage rack assembly is effectively connected to the left and right side enclosures and the lower body assembly 8 through the first side enclosure reinforcement beam assembly 5 and the second side enclosure reinforcement beam assembly 6, respectively, so that the overall structure of the rear of the vehicle body is stable, the torsional resistance is strong, and resonance and abnormal noise are avoided. The rear body structure of the present application has good processability and manufacturability, has the advantages of high structural strength and controllable cost, and can be applied on a large scale.
