DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0027] In the description of the utility model, it should be explained that the directions or position relations indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer" and the like are based on the directions or position relations shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and not to indicate or imply that the devices or elements indicated must have a particular direction, be constructed and operated in a particular direction, therefore, it cannot be understood as a limitation on the utility model.

[0028] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0029] In existing technologies, the transport space of current vehicles is fixed after the vehicle body is designed and cannot be expanded. In particular, the trunk space is limited, and the tailgate is generally a one-piece structure with a limited opening, which greatly restricts the transport capacity and cannot meet the needs of transporting some large items.

[0030] Regarding the above technical issues, such as Figures 1-3 As shown, this utility model provides a car tailgate assembly, including a sliding upper tailgate assembly 3 connected to an upper roof cover 1 and a lower tailgate 4 hinged to the trunk floor. The upper tailgate assembly 3 and the lower tailgate 4 are sealed together to ensure the airtightness of the tailgate assembly when closed. The upper tailgate assembly 3 includes a rear roof cover 2 connected to the upper roof cover 1 and an upper tailgate 3 that slides with it. This utility model divides the vehicle tailgate into an upper tailgate assembly 3 and a lower tailgate 4. The upper tailgate assembly 3 uses a sliding structure to open and close, allowing it to slide forward and backward; the lower tailgate 4 is hinged to the trunk floor and opens and closes by flipping. When the upper tailgate 3 is slid open, the vehicle's vertical space is expanded, which can meet the needs of transporting some large items and improve cargo capacity.

[0031] Specifically, such as Figures 1-3 As shown, the rear roof 2 and the upper tailgate 3 are designed with a fastback shape. The upper or lower surface of the rear roof 2 is provided with a sliding structure 21 along the vehicle direction, and the upper tailgate 3 is provided with a sliding rail structure 31 that slides in conjunction with the sliding structure 21. Figure 5 As shown, the slide structure 21 includes strip-shaped slides disposed on both sides of the rear top cover 2, the strip-shaped slides being arranged conformally to the shape of the rear top cover 2 on both sides; as Figure 4 As shown, the sliding rail structure 31 includes strip-shaped sliding rails disposed on both sides of the upper tailgate 3. The strip-shaped sliding rails slide in cooperation with the corresponding strip-shaped sliding rails, realizing the forward and backward sliding of the upper tailgate 3 relative to the rear top cover 2. The upper tailgate 3 can slide along the rear top cover 2 by a motor drive, that is, the above-mentioned sliding rail structure 21 can be set as a linear guide rail driven by a motor. The slider on the linear guide rail is fixedly connected to the sliding rail structure 31. The upper tailgate 3 can be opened and closed by controlling the motor action through a button. Of course, it can also be opened manually.

[0032] like Figure 5 As shown, both ends of the slide structure 21 are equipped with stop blocks 22 to prevent the slide rail structure 31 from dislodging. These stop blocks 22 seal both ends of the slide structure 21, reliably limiting the closing of the upper tailgate 3. Furthermore, when the upper tailgate 3 is fully open, the rear top cover 2 is connected to the top of the upper tailgate 3 via a positioning structure. This positioning structure can be a magnetic suction structure, a snap-fit ​​structure, etc., to limit the opening position of the upper tailgate 3. All of the above structures ensure the stability and reliability of the sliding opening and closing of the upper tailgate 3.

[0033] The sliding structure between the rear roof 2 and the upper tailgate 3 can be configured in the following two ways: one structure is, as follows: Figures 1-3 As shown, the slide structure 21 is set on the upper surface of the rear top cover 2, and the slide rail structure 31 is set on the lower surface of the upper tailgate 3; and the length of the upper tailgate 3 is greater than the length of the rear top cover 2, and after the upper tailgate 3 slides upward into place, it covers the rear top cover 2, ensuring the sealing effect of the entire upper tailgate 3 assembly in the open and closed state, and the overall design is more reasonable.

[0034] Another structure, not shown in the figure, is a sliding track structure 21 located on the lower surface of the rear top cover 2 and a sliding rail structure 31 located on the upper surface of the upper tailgate 3. The longitudinal section of the sliding track structure 21 can be set in a dovetail shape to prevent the lower upper tailgate 3 from detaching from the rear top cover 2 due to gravity. The length of the upper tailgate 3 is less than the length of the rear top cover 2. After the upper tailgate 3 slides upward into place, the rear top cover 2 covers the upper tailgate 3, making the upper tailgate 3 more integrated when opened.

[0035] Specifically, such as Figure 4 As shown, an annular sealing strip I32 is installed circumferentially on one side of the upper tailgate 3 that slides with the rear top cover 2. The annular sealing strip I32 surrounds the outside of the slide rail structure 31 and is in sealing fit with the lower tailgate 4. Figure 5 As shown, the upper cover 1 is provided with an annular sealing strip II 23 in circumferential contact with the vehicle body. The annular sealing strip I 32 and the annular sealing strip II 23 ensure the sealing between the entire upper tailgate 3 assembly and the vehicle body, preventing rainwater from entering the trunk and ensuring the sealing effect of the overall structure of the tailgate assembly.

[0036] In addition, the upper cover 1 and the rear cover 2 are fixed or hinged together. When the upper cover 1 and the rear cover 2 are hinged together, the transport space can be further expanded by flipping upwards, which can further improve the cargo carrying capacity.

[0037] like Figure 1 , 2 As shown in Figure 6, the lower tailgate 4 is hinged to the trunk floor. The lower tailgate 4 has an arc-shaped, inwardly folded structure, including an arc-shaped section 41 and an L-shaped bent sealing section 42. The arc-shaped section 41 further increases the trunk space, while the bent sealing section 42 ensures a sealed connection with the upper tailgate 3. The lower tailgate 4 can be opened and closed manually or electrically.

[0038] This utility model also protects an automobile, including the aforementioned automobile tailgate assembly.

[0039] In summary, this utility model expands the vehicle's transport space and improves its cargo capacity by changing the integral structure of the tailgate to a split structure and altering its opening method.

[0040] The above is only to illustrate some principles of the present application by means of figures, and the present application is not limited to the specific structures and application scope shown and described, so all possible modifications and equivalents that can be utilized belong to the patent scope of the present application.
