[0068] As a specific implementation of the flip mechanism, see Figure 8The flip mechanism includes a right partition mounting hinge 5-1 and a left partition mounting hinge 5-10 symmetrically arranged in the transverse direction. The lower body assembly 4 includes a right partition hinge mounting seat for mounting the right partition mounting hinge 5-1 and a left partition hinge mounting seat for mounting the left partition mounting hinge 5-10. In order to ensure the structural strength of the hinge connection, the right partition mounting hinge 5-1 and the left partition mounting hinge 5-10 are both provided with two mounting columns. Correspondingly, the right partition hinge mounting seat includes a right partition hinge lower mounting seat 4-1 and a right partition hinge upper mounting seat 4-2. The upper and lower The mounting seats are formed with a mounting hole for connecting the two mounting posts of the right partition mounting hinge 5-1. The left partition hinge mounting seat includes a left partition hinge lower mounting seat 4-5 and a left partition hinge upper mounting seat 4-6. The upper and lower mounting seats are formed with a mounting hole for connecting the two mounting posts of the left partition mounting hinge 5-10. In addition, the partition main body frame 5-13 is provided with a locking mechanism for locking the partition main body frame 5-13 on the frame body, so as to fix the partition main body frame 5-13 without flipping the partition main body frame 5-13. It should be noted that in the process of flipping the partition main body frame 5-13, in order to avoid interference with surrounding components to form a limit position and fail to flip into place, a reserved space for flipping is provided between the bottom crossbeam of the partition main body frame 5-13 and the rear floor crossbeam 4-4.

[0069] As a specific structural form of the locking mechanism, the locking mechanism includes a right partition lock buckle 5-2 and a left partition lock buckle 5-9 respectively arranged on the lateral sides of the partition main frame 5-13, a right partition lock buckle mounting plate 1-4 for mounting the right partition lock buckle 5-2 is arranged on the right middle column, and a left partition lock buckle mounting plate 3-4 for mounting the left partition lock buckle 5-9 is arranged on the left middle column of the left side rear inner plate assembly 3, and the right partition lock buckle 5-2 and the left partition lock buckle 5-9 are both provided with a partition lock 5-18 for locking the partition main frame 5-13, see Figure 1 , Figure 8 and Fig.10 The left partition lock mounting plate 3-4 is integrally formed on the lower section 3-3 of the left center column, and the left partition lock 5-9 is fixedly installed on the left partition lock mounting plate 3-4 by the partition lock mounting screws, so that it can be connected to the right side enclosure to ensure the structural strength of the connection. The partition main body frame 5-13 is locked on the left partition lock 5-9 by the partition lock 5-18, thereby forming a fixed connection. However, when the partition main body frame 5-13 needs to be flipped, it is only necessary to unlock the partition locks 5-18 on both sides of the lateral side, so that the partition main body frame 5-13 can be flipped along the flip axis of the structure as shown in FIG. Figure 2In addition, the right side rear inner panel assembly 1 and the left side rear inner panel assembly 3 are symmetrical in structure, so the connection structure between the right partition lock buckle 5-2 and the right side rear inner panel assembly 1 and the connection structure between the left partition lock buckle 5-9 and the left side rear inner panel assembly 3 are symmetrical in structure. It should be noted that when the partition main frame 5-13 is reset after flipping, it needs to be restored to a fixed position to facilitate the locking of the partition lock 5-18. As a preferred embodiment, see Figure 4 and Figure 6 A right partition limiter mounting plate 1-1 is provided on the lower section 1-3 of the right center column, and a left partition limiter mounting plate 3-1 is provided on the lower section 3-3 of the left center column, so that limiters are installed on the left and right sides. When the partition main frame 5-13 is flipped and reset, the limiter can limit the partition main frame 5-13 to prompt that the partition main frame 5-13 has been flipped into place, so as to facilitate the locking of the partition lock 5-18.

[0070] As a specific embodiment of the present invention, see Figure 1 and Figure 8 The partition assembly 5 includes a partition upper frame 5-15 which is separately arranged from the partition main body frame 5-13, and the partition upper frame 5-15 is connected to the top cover cavity 400. A partition glass 5-11 and a partition glass lifter 5-12 for driving the partition glass 5-11 to move up and down are movably installed in the partition main body frame 5-13. When the partition glass 5-11 rises to the limit state, the partition glass 5-11 is pressed against and clamped in the partition glass groove 5-17 of the partition upper frame 5-15 to form a seal. By setting the partition glass 5-11, the personnel in the passenger compartment can observe the space in the rear luggage compartment, and the driver can observe the situation of the rear vehicle through the partition glass 5-11 through the rearview mirror. At the same time, when the partition glass 5-11 is raised to the limit state, the passenger compartment can also be sealed. The partition assembly 5 is generally located on the rear wheel hub package, so it can effectively achieve sound insulation and noise reduction, and can also isolate the function of luggage compartment odor, and also prevent the cold / warm air flow in the passenger compartment from entering the luggage compartment. When the personnel in the passenger compartment want to take the items in the luggage compartment, they can also directly lower the partition glass 5-11, so that the passenger compartment and the luggage compartment are connected through the space formed by the upper frame 5-15 and the upper part of the partition main frame 5-13, so as to take the items.

[0071] The top cover cavity 400 is connected to the right side enclosure cavity and the left side enclosure cavity respectively. In order to further strengthen the structural strength of the connection between the partition upper frame 5-15 and the frame body, the lateral ends of the partition upper frame 5-15 are respectively connected to the upper part of the right side enclosure cavity and the upper part of the left side enclosure cavity. The partition upper frame 5-15 is fixed together by the right side enclosure cavity, the left side enclosure cavity and the top cover cavity 400.

[0072] Specifically, the partition upper frame 5-15 is provided with a plurality of partition upper frame connecting members, see Figure 8 In the specific embodiment shown, the plurality of partition upper frame connectors include a partition upper frame connector 1 5-3, a partition upper frame connector 2 5-4, a partition upper frame connector 3 5-5, a partition upper frame connector 4 5-6, a partition upper frame connector 5 5-7 and a partition upper frame connector 6 5-8 arranged sequentially from right to left, wherein, see Figure 1 The partition upper frame connecting member 3 5-5 and the partition upper frame connecting member 4 5-6 located in the middle are connected to the top cover cavity 400 of the top cover middle cross beam assembly 2, and a corresponding partition top mounting bracket is arranged on the top cover cavity 400, including a partition top mounting bracket 1 2-3 and a partition top mounting bracket 2 2-4 fixedly connected to the top cover middle cross beam inner plate 2-1, see Fig. 9 The partition upper frame connecting piece 4 5-6 is connected to the partition top mounting bracket 1 2-3 through the connecting bolt 5-20; the partition upper frame connecting piece 1 5-3 and the partition upper frame connecting piece 2 5-4 located on the right side are connected to the right side enclosure cavity of the right side enclosure rear inner panel assembly 1, see Figure 4 A right partition side lower mounting bracket 1-6 corresponding to the partition upper frame connecting piece 1 5-3 is arranged on the upper section 1-7 of the right center pillar, and a right partition side upper mounting bracket 1-9 corresponding to the partition upper frame connecting piece 2 5-4 is arranged on the right connecting inner plate 1-10 of the top cover; the partition upper frame connecting piece 5-7 and the partition upper frame connecting piece 6 5-8 located on the left side are connected to the left side enclosure cavity of the left side enclosure rear inner plate assembly 3, see Figure 6 A left partition side lower mounting bracket 3-6 corresponding to the partition upper frame connecting piece 1 5-3 is provided on the upper section 3-7 of the left center column, and a left partition side upper mounting bracket 3-9 corresponding to the partition upper frame connecting piece 2 5-4 is provided on the left connecting inner plate 3-10 of the top cover middle cross beam.

[0073] It should be noted that when the partition assembly 5 is installed, the interior decoration will be installed, see Figure 5 and Figure 8A top interior decoration mounting bracket 2-2 and a top interior decoration mounting bracket 2-5 are arranged on the inner plate 2-1 of the middle cross beam of the top cover. In order to ensure that the connection of the top interior decoration is firm and reliable, a plurality of connection points are arranged between the top interior decoration mounting bracket 2-2 and the top interior decoration mounting bracket 2-5. In order to improve the integration degree of the inner plate 2-1 of the middle cross beam of the top cover and reduce the space occupation, the partition top mounting bracket 1 2-3 and the partition top mounting bracket 2 2-4 are also integrated with mounting holes for installing the top interior decoration. In addition, a plurality of partition lower interior decoration mounting brackets 5-16 are also integrated on the bottom cross beam of the partition main frame 5-13. While improving the integration degree, the interior decoration on the partition assembly 5 can be flipped together with the partition main frame 5-13.

[0074] In order to further enhance the structural strength of the partition main frame 5-13, see Figure 8 The partition main frame 5-13 is provided with partition reinforcement columns 5-14, and the two ends of the partition reinforcement columns 5-14 are respectively connected to the middle sections of the beams on the upper and lower sides of the partition main frame 5-13, thereby forming a force transmission channel to avoid deformation of the partition main frame 5-13 and causing the partition glass 5-11 to be crushed and damaged, and at the same time, it can also play a certain protective role for the partition glass 5-11.

Therefore, the annular frame structure for installing the partition assembly 5 formed by the frame cavity and the rear floor cross beam 4-4 can greatly improve the rigidity and strength, thereby ensuring the reliability of the installation area of ​​the partition assembly 5. In addition, the partition assembly 5 is designed to be flippable and the partition glass 5-11 is designed to be liftable, which can greatly meet consumers' needs for vehicle use. According to actual conditions, the partition assembly 5 can be flipped or the partition glass 5-11 can be lowered to achieve connectivity between the passenger compartment and the luggage compartment.
