[0069] As a specific structure form of the locking mechanism, the locking mechanism includes right partition lock catch 5-2 and left partition lock catch 5-9 arranged on the transverse two sides of the partition body framework 5-13 respectively, the right intermediate pillar is provided with right partition lock catch mounting plate 1-4 for mounting right partition lock catch 5-2, the left side wall rear inner plate assembly 3 is provided with left partition lock catch mounting plate 3-4 for mounting left partition lock catch 5-9 on the left intermediate pillar, right partition lock catch 5-2 and left partition lock catch 5-9 are provided with partition lock 5-18 for locking the partition body framework 5-13, see Figure 1 、 Figure 8 and Figure 10 , the left partition lock catch mounting plate 3-4 is integrally formed on the left intermediate pillar lower section 3-3, the left partition lock catch 5-9 is fixedly installed on the left partition lock catch mounting plate 3-4 through partition lock catch mounting screw, so as to be connected on the right side wall cavity, ensuring the structural strength of the connection, the partition body framework 5-13 is locked on the left partition lock catch 5-9 through the partition lock 5-18, so as to form a fixed connection, but when the partition body framework 5-13 needs to be turned over, only the partition lock 5-18 on the transverse two sides needs to be unlocked, so that the partition body framework 5-13 can be turned along the turnover axis of the turnover structure, such as Figure 2The right rear inner panel assembly 1 is rotated, and the structure of the right rear inner panel assembly 1 and the left rear inner panel assembly 3 is symmetrical, so the connection structure of the right partition lock catch 5-2 and the right rear inner panel assembly 1 and the connection structure of the left partition lock catch 5-9 and the left rear inner panel assembly 3 are symmetrical. It should be noted that when the partition main body framework 5-13 is reset after being flipped, 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 arranged on the right middle pillar lower section 1-3, and a left partition limiter mounting plate 3-1 is arranged on the left middle pillar lower section 3-3, so that limiters are installed on the left and right sides. When the partition main body framework 5-13 is reset after being flipped, the limiters can limit the partition main body framework 5-13, prompting the partition main body framework 5-13 to be flipped in place, and facilitating the locking of the partition lock 5-18.

[0070] As a specific embodiment of the present application, see Figure 1 and Figure 8 The partition assembly 5 includes a partition upper frame 5-15 arranged separately from the partition main body framework 5-13.

The partition main body framework 5-13 movably installs a partition glass 5-11 and a partition glass lifter 5-12 for driving the partition glass 5-11 to move up and down. When the partition glass 5-11 is raised to the limit state, the partition glass 5-11 abuts and clamps in the partition glass groove 5-17 of the partition upper frame 5-15 to form a seal. By arranging the partition glass 5-11, the space in the rear luggage compartment can be observed by the personnel in the passenger compartment, and the driver can observe the rear approaching vehicle through the partition glass 5-11. When the partition glass 5-11 is raised to the limit state, the passenger compartment is also sealed. The partition assembly 5 is generally located on the rear hub cover, so it can effectively realize sound insulation and noise reduction, and can also isolate the odor of the luggage compartment. It also avoids the cold / hot air flow in the passenger compartment into the luggage compartment. When the personnel in the passenger compartment want to take the items in the luggage compartment, the partition glass 5-11 can be directly lowered, 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 body framework 5-13, thereby taking the items.

[0071] The roof cavity 400 is in communication with the right side wall cavity and the left side wall cavity. In order to further strengthen the structural strength of the connection between the partition upper frame 5-15 and the frame main body, the transverse ends of the partition upper frame 5-15 are connected to the upper parts of the right side wall cavity and the left side wall cavity, respectively. The partition upper frame 5-15 is fixed by the right side wall cavity, the left side wall cavity, and the roof cavity 400.

[0073] It should be noted that when the partition assembly 5 is installed, the interior trim is installed, see Figure 5 and Figure 8The top inner decoration mounting bracket 2-2 and the top inner decoration mounting bracket two 2-5 are arranged on the roof cross beam inner plate 2-1 in the top cover, and a plurality of connection points are arranged between the top inner decoration mounting bracket 2-2 and the top inner decoration mounting bracket two 2-5 to ensure that the connection of the top inner decoration is stable and reliable. In order to improve the integration degree of the roof cross beam inner plate 2-1 and reduce the space occupation, the partition top mounting bracket one 2-3 and the partition top mounting bracket two 2-4 are further integrated with mounting holes for mounting the top inner decoration. In addition, a plurality of partition lower inner decoration mounting brackets 5-16 are integrated on the bottom cross beam of the partition main body framework 5-13, which improves the integration degree and also enables the inner decoration on the partition assembly 5 to be flipped together with the partition main body framework 5-13.

[0074] In order to further strengthen the structural strength of the partition main body framework 5-13, referring to Figure 8 , the partition main body framework 5-13 is provided with a partition reinforcing column 5-14, and the two ends of the partition reinforcing column 5-14 are respectively connected to the middle sections of the cross beams on the upper and lower sides of the partition main body framework 5-13, thereby forming a force transmission channel, avoiding deformation of the partition main body framework 5-13, causing the partition glass 5-11 to be damaged by pressure, and also being able to play a certain protective role for the partition glass 5-11.

The frame cavity is connected to the lower vehicle body welding assembly 4, which is an integrated cast aluminum structural member, has an excellent structure, and therefore the annular frame structure for mounting the partition assembly 5 formed by the frame cavity and the rear floor beam 4-4 can greatly improve the rigidity and strength, and ensure the reliability of the partition assembly 5 installation area. In addition, the partition assembly 5 is designed to be reversible and the partition glass 5-11 is designed to be liftable, which can greatly meet the use requirements of consumers for vehicles, and the partition assembly 5 can be reversed or the partition glass 5-11 can be lowered according to actual conditions, thereby realizing the communication of the passenger compartment and the luggage compartment space. At the same time, the right partition stopper mounting plate 1-1, the right partition lock buckle mounting plate 1-4, the right partition side lower mounting bracket 1-6 and the right partition side upper mounting bracket 1-9 are integrally arranged on the right side wall cavity, the left partition stopper mounting plate 3-1, the left partition lock buckle mounting plate 3-4, the left partition side lower mounting bracket 3-6 and the left partition side upper mounting bracket 3-9 are integrally arranged on the left side wall cavity, and the partition top mounting bracket 2-3 and the partition top mounting bracket 2-4 are integrally arranged on the roof cavity 400, so that the structure for mounting the partition assembly is directly connected with the frame cavity, effectively improving the structural strength and reliability of the mounting part, and the mounting structure is designed to be integrated with the vehicle body framework, without the need to add new parts, simplifying the structure, facilitating assembly, and having good economy.
