[0083] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0084] The following description, with reference to Figures 1-10, describes a vehicle support device 100 provided in an embodiment of this application. The vehicle support device 100 is applied to a trunk assembly, which includes a trunk body forming a storage space 200. The vehicle support device 100 includes a trunk cover 110 and a transmission mechanism 120. The transmission mechanism 120 is at least disposed between the trunk cover 110 and the trunk body. The transmission mechanism 120 causes the vehicle support device 100 to have at least a first state and a second state relative to the trunk body. In the first state, the trunk cover 110 extends horizontally and is located within the storage space 200; in the second state, the trunk cover 110 extends horizontally and is at least partially located outside the storage space 200.

[0085] In this embodiment, considering that the opening of the storage space 200 faces backward, the horizontal direction refers to the front-to-back direction of the vehicle.

[0086] Understandably, in its first state, the trunk lid 110 lies flat within the storage space 200 to accommodate items inside the vehicle, maximizing the storage capacity of the storage space 200. In its second state, the trunk lid 110 extends at least partially outside the vehicle through the opening of the storage space 200, still extending horizontally. This not only expands the space for storing items but also allows the trunk lid 110 to be used as an additional workbench or seat during outdoor activities (such as fishing, sightseeing, or picnicking), providing additional functionality and increasing the vehicle's practicality.

[0087] It should be noted that the trunk lid 110 can be maintained in the first state by using the horizontal ribs protruding from the storage space 200 on the left and right side walls, or by designing a locking structure; the trunk lid 110 can be maintained in the second state by using the rear door threshold 300 of the trunk assembly, or by designing a locking structure. This embodiment does not impose specific limitations on this.

[0088] In some embodiments, as shown in FIG5, the height of the trunk lid 110 in the first state is lower than the height of the trunk lid 110 in the second state.

[0089] It is understandable that, referring to Figure 1, when the height of the tailgate sill 300 is greater than the height of the trunk lid 110 when it is laid flat in the storage space 200, the transmission structure makes the height of the trunk lid 110 in the second state higher than the height of the trunk lid 110 in the first state. This allows the trunk lid 110 to be used in environments where the height of the tailgate sill 300 is higher than the height of the trunk lid 110 in the first state, ensuring the storage function of the trunk lid 110 while improving the applicability and flexibility of the vehicle support device 100.

[0090] According to the vehicle support device 100 provided in the embodiments of this application, the transmission mechanism 120 disposed between the trunk cover 110 and the trunk body ensures the storage function of the trunk cover 110 while improving the applicability and flexibility of the vehicle support device 100.

[0091] In some embodiments, as shown in FIG5, the trunk lid 110 has a first surface 111 and a second surface 112 disposed opposite to each other. When the vehicle support device 100 is in a first state, the first surface 111 is located above the second surface 112; when the vehicle support device 100 is in a second state, the second surface 112 is located above the first surface 111.

[0092] It is understood that in the first state, the first surface 111 is located above the second surface 112, that is, the first surface 111 is used for placing items, and the second surface 112 serves a supporting function; in the second state, the second surface 112 is located above the first surface 111, that is, the second surface 112 is used for placing items, and the first surface 111 serves a supporting function. Simultaneously, the transmission mechanism 120 enables the trunk lid 110 to flip when switching between the first and second states, making the trunk lid 110 more intuitive and convenient to use. Compared to linear motion structures such as telescopic structures, this makes the structure of the vehicle support device 100 more compact and simpler, reducing the risk of mechanical failure and lowering maintenance costs. Of course, in some other embodiments, a linear motion mechanism with forward and backward movement and up and down movement functions can also be used to set an intermediate state between the first and second states or to adjust the second state; this embodiment does not impose specific limitations on this.

[0093] In some embodiments, as shown in Figures 2 to 10, the transmission mechanism 120 includes a first support 121, a first connecting rod 122, a second support 123, and a second connecting rod 124. The first support 121 is disposed within the storage space 200. The two ends of the first connecting rod 122 are hinged to the first support 121 and the trunk lid 110, respectively. The second support 123 is disposed within the storage space 200. The two ends of the second connecting rod 124 are hinged to the second support 123 and the trunk lid 110, respectively. The hinge point of the first support 121 and the first connecting rod 122 is located on the side of the second support 123 and the second connecting rod 124 away from the opening of the storage space 200, and the hinge point of the first support 121 and the second connecting rod 124 is lower than the hinge point of the second support 123 and the second connecting rod 124.

[0094] It should be noted that, since the hinge points of the first support 121 and the first connecting rod 122 are located in front of the hinge points of the second support 123 and the second connecting rod 124, and the hinge points of the first support 121 and the second connecting rod 124 are lower than the hinge points of the second support 123 and the second connecting rod 124, it helps to achieve the simultaneous vertical and horizontal movement of the trunk lid 110 while it flips 180°.

[0095] Understandably, the trunk lid 110 is hinged to the first link 122 and the second link 124, respectively. The ends of the first link 122 and the second link 124 away from the trunk lid 110 are hinged to the first support 121 and the second support 123, respectively. This forms a four-bar linkage between the first link 122, the second link 124, and the trunk lid 110, enabling the trunk lid 110 to perform complex movements within the limited storage space 200. Simultaneously, the hinged design provides high rigidity to the entire transmission mechanism 120, allowing it to withstand large loads while maintaining stable movement. Furthermore, by adjusting the lengths of the first link 122 and the second link 124, stable support for the trunk lid 110 can be achieved at different heights and positions, adapting to various usage needs.

[0096] In some embodiments, as shown in Figures 2 to 4, 7 and 10, there are two first supports 121 and two first connecting rods 122. The first supports 121 and the first connecting rods 122 correspond one-to-one and are hinged together. The second support 123 is located between the two first supports 121.

[0097] Understandably, the two first supports 121 are respectively located on the left and right sides of the luggage compartment cover 110, and the second support 123 is located in the middle of the two first supports 121, so as to support the weight of the luggage compartment cover 110 more evenly and help maintain the stability and balance of the luggage compartment cover 110 during the flipping process.

[0098] In some embodiments, as shown in Figures 2 to 5, the hinge points of the trunk lid 110 and the first link 122, as well as the hinge points of the trunk lid 110 and the second link 124, are located on the same side of the trunk lid 110 in the horizontal direction. This allows the trunk lid 110 to be flipped around its end in the front-rear direction to extend or retract the storage space 200, reducing the complexity of the transmission mechanism 120, minimizing its impact on the storage space 200, providing a better force transmission path, and facilitating maintenance and repair. Since all hinge points are located on the same side, maintenance and repair work can be more concentrated and convenient.

[0099] In this embodiment, as shown in FIG5, in the first state, the hinge point of the trunk lid 110 and the first connecting rod 122 is located at the rear end of the trunk lid 110; the hinge point of the trunk lid 110 and the second connecting rod 124 is located in front of the hinge point of the trunk lid 110 and the first connecting rod 122, and close to the rear end of the trunk lid 110; in the second state, the hinge point of the trunk lid 110 and the first connecting rod 122 is located at the front end of the trunk lid 110, and the hinge point of the trunk lid 110 and the second connecting rod 124 is located behind the hinge point of the trunk lid 110 and the first connecting rod 122, and close to the front end of the trunk lid 110.

[0100] In some embodiments, as shown in Figures 6 to 9, the second link 124 includes a first segment 1241, a second segment 1242, and a third segment 1243. One end of the first segment 1241 is hinged to the second support 123; one end of the second segment 1242 is connected to the other end of the first segment 1241 at an acute angle; one end of the third segment 1243 is connected to the other end of the second segment 1242 at an acute angle or a right angle; and the other end of the third segment 1243 is hinged to the trunk lid 110.

[0101] It should be noted that when switching from the first state to the second state, the first segment 1241 rotates forward and upward (from the perspective of Figure 5), the first connecting rod 122 rotates clockwise, and the third segment 1243 and the first connecting rod 122 apply a downward force to the end of the trunk lid 110 near the first support 121, thereby causing the trunk lid 110 to rotate 180° around the end near the first support 121. When switching from the second state to the first state, the first segment 1241 rotates clockwise, the first connecting rod 122 rotates counterclockwise, and the third segment 1243 and the first connecting rod 122 apply a downward force to the end of the trunk lid 110 near the first support 121, thereby causing the trunk lid 110 to rotate 180° around the end near the first support 121.

[0102] Understandably, one end of the second segment 1242 and the end of the first segment 1241 away from the second support 123 are connected at an acute angle, which helps to change the direction of the force and reduce interference with other parts during the state switching process of the trunk lid 110; the other end of the second segment 1242 and the end of the third segment 1243 away from the trunk lid 110 are connected at an acute angle or a right angle, which helps to change the direction of the force again, thereby enabling the trunk lid 110 to flip within a limited space.

[0103] In some embodiments, as shown in Figures 6 to 9, the first segment 1241 and the second segment 1242 are smoothly connected to form a continuous force transmission path, ensuring the smoothness of the second link 124 during movement, making more efficient use of space, reducing stress concentration, and thus improving the durability and service life of the second link 124.

[0104] In some embodiments, as shown in Figures 6 and 9, the trunk lid 110 is provided with a groove 113, which extends horizontally, and the end of the third segment 1243 away from the second segment 1242 is hinged within the groove 113. It should be noted that the shape and size of the groove 113 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0105] Understandably, by hinged at the end of the third segment 1243 within the groove 113, sufficient range of motion is provided for the second link 124 without increasing additional space occupation, and the hinge point between the third segment 1243 and the trunk lid 110 is made closer to the center of the lid, thereby enhancing the stability and load-bearing capacity of the entire vehicle support device 100.

[0106] In some embodiments, as shown in Figures 6 and 9, the groove 113 has a first opening 1131 and a second opening 1132. In a second state, the first opening 1131 faces the storage space 200 in a horizontal direction, the second opening 1132 faces upward, and the third segment 1243 is located in the groove 113, and the second segment 1242 abuts against the trunk lid 110.

[0107] It is understood that the groove 113 is at least partially provided on the second surface 112. That is, in the first state, the first opening 1131 faces rearward, the second opening faces downward 1132, and the second segment 1242 and the third segment 1243 are both located below the trunk lid 110. In the second state, the first opening 1131 faces forward, the second opening 1132 faces upward, and the third segment 1243 is located in the groove 113 and plays a positioning role, which helps to maintain the stability of the connection between the third link 1251 and the trunk lid 110, and ensures that the trunk lid 110 will not shift during the flipping process. The second segment 1242 abuts against the front end face of the trunk lid 110, which can increase the contact area, provide better support and limiting effect, and ensure that the trunk lid 110 can remain stable when flipped to the second state.

[0108] In this embodiment, as shown in Figures 7 and 9, the second segment 1242 and the third segment 1243 are connected at right angles, and in the second state, the upper surface of the second segment 1242 and the surface of the second surface 112 near the second opening 1132 are spliced ​​together to form a continuous plane.

[0109] Understandably, the second segment 1242 and the third segment 1243 are connected at right angles to bear and share greater load-bearing capacity, improving the stability of the trunk lid 110 in the second state. This also provides a flat working surface for the continuous plane formed by the second segment 1242 and the second surface 112, reducing the possibility of dust and debris entering the groove 113 while placing items, and reducing the possibility of dust and debris entering the storage space 200 after switching from the second state to the first state.

[0110] In some embodiments, as shown in Figures 1 to 8, the vehicle support device 100 further includes a table 130, which is connected to the trunk lid 110 and has a stowed state and an open state; wherein, when the trunk lid 110 is in the first state, the table 130 is in the stowed state; and when the trunk lid 110 is in the second state, the table 130 is in the open state.

[0111] Understandably, when the luggage lid 110 is laid flat within the storage space 200, the tabletop 130 is in a retracted state to reduce space occupation and minimize impact on the storage space 200; when the luggage lid 110 is laid flat and at least partially extends out of the storage space 200, the tabletop 130 is in an open state to provide a flat working surface in environments such as outdoor activities, picnics, or emergency repairs.

[0112] In some embodiments, when the trunk lid 110 is in the first state, the table 130 is located below the second surface 112; when the trunk lid 110 is in the second state, the table 130 is located above the second surface 112.

[0113] Understandably, when the trunk lid 110 is in the first state, the table 130 is located below the trunk lid 110, thus ensuring that the table 130 does not occupy extra space while the trunk lid 110 is used for placing items in the storage space 200; when the trunk lid 110 is in the second state, the table 130 is located above the trunk lid 110 as the trunk lid 110 is flipped, providing additional storage function and increasing the practicality of the vehicle.

[0114] In some embodiments, as shown in Figures 3 to 9, the transmission mechanism 120 further includes a first linkage component, which is disposed between the trunk lid 110, the table 130, and the second link 124, for synchronizing the movement of the trunk lid 110 and the table 130.

[0115] It is understandable that, through the first linkage component, when the luggage compartment lid 110 switches from the first state to the second state, the table 130 correspondingly switches from the folded state to the open state, and when the luggage compartment lid 110 switches from the second state to the first state, the table 130 correspondingly switches from the open state to the folded state. This linkage design between the table 130 and the luggage compartment lid 110 improves ease of use and reduces potential instability or safety hazards that might arise from operating the table 130 independently. Of course, in some other embodiments, the switching between the open and folded states of the table 130 can also be achieved manually to increase flexibility of use; this embodiment does not impose specific limitations on this.

[0116] In some embodiments, as shown in Figures 3 to 9, the first linkage assembly includes a third link 1251, a fourth link 1252, and a fifth link 1253. One end of the third link 1251 is hinged to the second link 124. The first end of the fourth link 1252 is hinged to the other end of the third link 1251, and the first end of the fourth link 1252 is slidably engaged with the trunk lid 110 in the horizontal direction. The second end of the fourth link 1252 is hinged to the table 130. One end of the fifth link 1253 is hinged to the trunk lid 110, and the other end of the fifth link 1253 is slidably engaged with the table 130. The middle portion of the fourth link 1252 is hinged to the middle portion of the fifth link 1253.

[0117] It should be noted that by hinged one end of the third link 1251 to the second link 124, the trunk lid 110 will move during the flipping process via the second link 124, thereby causing the fourth link 1252, which is hinged to the third link 1251, to slide relative to the trunk lid 110 in the front-back direction. At the same time, the end of the fifth link 1253 away from the trunk lid 110 rotates relative to the table 130 and slides in the front-back direction, so that the table 130 can move closer to or away from the second surface 112.

[0118] Understandably, when the first link 122 rotates clockwise, the second link 124 rotates counterclockwise, and the third link 1251 rotates towards the second surface 112, the fourth link 1252 slides along the front-back direction towards the first link 122 and the first support 121, while rotating away from the second surface 112 around the hinge point with the third link 1251. At the same time, the fifth link 1253, which is hinged to the fourth link 1252, slides along the front-back direction towards the first link 122 and the first support 121, while rotating away from the second surface 112 around the hinge point with the planetary case cover. This causes the tabletop 130 to move away from the second surface 112 and be positioned above it, so that the luggage compartment cover 110 is in the second state and the tabletop 130 is in the open state.

[0119] Similarly, when the first link 122 rotates counterclockwise, the second link 124 rotates clockwise, and the third link 1251 rotates away from the second surface 112, the fourth link 1252 slides away from the first link 122 and the first support 121 along the front-back direction, and rotates towards the second surface 112 with the hinge point with the third link 1251 as the center. At the same time, the fifth link 1253, which is hinged to the fourth link 1252, slides away from the first link 122 and the first support 121 along the front-back direction, and rotates towards the second surface 112 with the hinge point with the planetary case cover as the center. This causes the tabletop 130 to be close to the second surface 112 and below the second surface 112, so that the luggage case cover 110 is in the first state and the tabletop 130 is in the storage state.

[0120] In some embodiments, as shown in FIG9, the middle part of the third segment 1243 and the third link 1251 are hinged.

[0121] Understandably, when the trunk lid 110 is flipped, the movement of the second link 124 is transmitted to the third link 1251 through this hinge point, which in turn affects the movement of the fourth link 1252 and the fifth link 1253. By hinged between the middle of the third segment 1243 and the third link 1251, the stability of the entire vehicle support device 100 can be enhanced, reducing the swaying that may occur when flipping or adjusting the table 130, while also reducing the instability and safety hazards caused by an excessively long force transmission path.

[0122] In some embodiments, as shown in FIG9, the hinge point of the third link 1251 and the third segment 1243 is located outside the groove 113, thereby reducing the mutual interference between the movement of the second link 124, the third link 1251 and the luggage compartment cover 110, and ensuring that the third link 1251 extends in the front-back direction in the second state, so as to ensure that the table 130 can maintain a stable support position in the use state.

[0123] In some embodiments, as shown in Figures 3 to 5, 7 and 8, there are two fourth links 1252. The third link 1251 includes a connecting section 12510 and two oppositely arranged support arms 12511. The connecting section 12510 is hinged to the second link 124. The support arms 12511 and the fourth links 1252 correspond one-to-one. One end of the support arm 12511 is connected to the connecting section 12510, and the other end of the support arm 12511 is hinged to the corresponding fourth link 1252.

[0124] Understandably, the two second connecting rods 124 are arranged opposite each other in the left-right direction, one end of the connecting section 12510 is hinged to the middle of the third section 1243, the two support arms 12511 are L-shaped and symmetrically arranged, one end of the two support arms 12511 extending in the left-right direction is connected to the other end of the connecting section 12510, and the two support arms 12511 extending in the front-back direction and the end away from the connecting section 12510 is hinged to the fourth connecting rod 1252, thereby increasing the contact area and distributing the load, enhancing the stability of the vehicle support device 100, so that the table 130 is more stable in the open state and is not easy to shake or deform.

[0125] In some embodiments, as shown in Figures 7 and 8, the first linkage assembly further includes a sixth link 1254, which is hinged through the fifth link 1253, and both ends of the sixth link 1254 are respectively hinged to two fourth links 1252.

[0126] Understandably, by connecting the sixth link 1254 to both the fifth link 1253 and the two fourth links 1252, the movement of the fourth link 1252 can be transmitted to the fifth link 1253 via the sixth link 1254, ensuring that the movement of the table 130 is synchronized with the flipping action of the luggage compartment lid 110. Simultaneously, the design of the sixth link 1254 increases the rigidity of the first linkage assembly, making the entire first linkage assembly more stable during movement.

[0127] In some embodiments, the fourth link 1252 and the third link 1251 are hinged by a first pivot, and a first rolling element is rotatably sleeved on the outside of the first pivot. A first guide rail 114 is provided on the side of the trunk lid 110 near the table 130, and the first rolling element reciprocates horizontally relative to the first guide rail 114. The first rolling element includes, but is not limited to, rollers.

[0128] Understandably, by setting a first rolling element that rotates relative to the first rotating shaft, and by allowing the first rolling element to move forward within the first guide rail 114, sliding friction is converted into rolling friction, reducing friction and wear, and improving the durability of the vehicle-mounted support device 100. Simultaneously, the first guide rail 114 provides stable guidance and limiting, contributing to improved motion accuracy and stability of the entire first linkage assembly.

[0129] In some embodiments, as shown in Figures 4, 6 and 7, the first guide rail 114 protrudes from the second surface 112, and the first guide rail 114 is provided with a first guide groove in the front-back direction. The first rolling element and the first guide groove are in rolling sliding cooperation, which also facilitates the support arm 12511 to move back and forth in the first guide groove. The opening of the first guide groove is oriented away from the second surface 112, so as to avoid the change of angle of the fourth link 1252.

[0130] In some embodiments, as shown in Figures 4, 6 and 7, there are two first guide rails 114, and the two first guide rails 114 correspond one-to-one with the two fourth connecting rods 1252.

[0131] In some embodiments, as shown in FIG8, the fifth link 1253 and the table 130 are hinged by the second pivot, and the second pivot is rotatably sleeved with the second rolling element. The side of the table 130 near the luggage compartment is provided with the second guide rail 131, and the second rolling element reciprocates in the horizontal direction relative to the second guide rail 131.

[0132] Understandably, by setting a second rolling element that rotates relative to the second rotating shaft, and by allowing the second rolling element to move forward within the second guide rail 131, sliding friction is converted into rolling friction, reducing friction and wear, and improving the durability of the vehicle-mounted support device 100. Simultaneously, the second guide rail 131 provides stable guidance and limiting, contributing to improved motion accuracy and stability of the entire first linkage assembly.

[0133] In some embodiments, as shown in FIG8, the second guide rail 131 protrudes from the tabletop 130 near the second surface 112, and the second guide rail 131 is provided with a second guide groove in the front-back direction. The second rolling element and the second guide groove are in rolling sliding cooperation, which also facilitates the fifth link 1253 to move back and forth in the second guide groove. The opening of the second guide groove faces closer to the second surface 112 to avoid changes in the angle of the fifth link 1253.

[0134] In some embodiments, as shown in FIG9, the hinge points of the fifth link 1253 and the trunk lid 110, the hinge points of the third link 1251 and the second link 124, and the hinge points of the second link 124 and the trunk lid 110 are all located on the vertical center plane of the trunk lid 110 in the left-right direction, ensuring the symmetry of the entire vehicle support device 100. This helps to maintain balance during state switching and reduces torque imbalance or torsion caused by asymmetry.

[0135] In some embodiments, as shown in Figures 1 to 5, the vehicle support device 100 further includes a seat 140, which is disposed on the trunk lid 110 and has a used state and a folded state; wherein, when the trunk lid 110 is in a first state, the seat 140 is in the folded state; and when the trunk lid 110 is in a second state, the seat 140 is in the used state. It should be noted that the number and distribution of the seats 140 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0136] Understandably, when the trunk lid 110 is laid flat within the storage space 200, the seat 140 is folded down to reduce space occupation and impact on the storage space 200; when the trunk lid 110 is laid flat and at least partially extends out of the storage space 200, the seat 140 is in use to provide additional seating in outdoor activities, picnics, or emergency repairs, increasing the vehicle's practicality.

[0137] In some embodiments, as shown in FIG5, when the trunk lid 110 is in the first state, the seat 140 is located below the second surface 112; when the trunk lid 110 is in the second state, the seat 140 is located on the second surface 112.

[0138] Understandably, when the trunk lid 110 is in the first state, the seat 140 is located below the trunk lid 110, so that the seat 140 does not occupy extra space while the trunk lid 110 is used for placing items in the storage space 200; when the trunk lid 110 is in the second state, the seat 140 is placed on the trunk lid 110 as the trunk lid 110 is flipped, providing additional seating and increasing the practicality of the vehicle.

[0139] In some embodiments, as shown in FIG5, the seat 140 includes a backrest 141 and a seat cushion 142 pivotally connected by a pivot shaft 143. The seat cushion 142 is fixedly or integrally disposed with the trunk lid 110. In the folded state, the backrest 141 is at least partially stacked with the seat cushion 142. In the use state, the backrest 141 and the seat cushion 142 are connected at an angle.

[0140] Understandably, in the first state, the backrest 141 and the seat cushion 142 are at least partially fitted together by the pivot 143 to be in a folded state, thereby minimizing the space occupied by the seat 140 and reducing the impact on the storage space 200; in the second state, the backrest 141 and the seat cushion 142 are connected at an angle by the pivot 143 in order to provide the user with a comfortable sitting posture.

[0141] In some embodiments, as shown in Figures 1 to 5, the transmission mechanism 120 further includes a second linkage component, which is disposed between the trunk lid 110, the pivot shaft 143, and the second link 124, and is used to ensure that when the trunk lid 110 is switched from the first state to the second state, the seat 140 is simultaneously switched from the folded state to the used state.

[0142] It is understandable that, through the second linkage component, when the trunk lid 110 switches from the first state to the second state, the seat 140 correspondingly switches from the folded state to the usable state. The linkage design between the seat 140 and the trunk lid 110 improves the convenience of use and reduces the instability or safety hazards that may be caused by the seat 140 operating alone. Of course, in some other embodiments, the switching between the folded state and the usable state of the seat 140 can also be achieved manually, so that the vehicle support device 100 also has an intermediate state, in order to increase the flexibility of use. This embodiment does not impose specific limitations on this.

[0143] In some embodiments, as shown in Figures 3 to 5, the second linkage component includes a first gear 1261 and a gear set. The first gear 1261 is coaxially disposed at the hinge of the first connecting rod 122 and the trunk cover 110. The gear set is drivenly connected to the pivot shaft 143 and meshes with the first gear 1261.

[0144] Understandably, when the trunk lid 110 switches from the first state to the second state, it drives the first gear 1261 to rotate, which in turn drives the gear set meshing with the first gear 1261 to rotate, thereby causing the corresponding pivot shaft 143 to rotate to switch the seat 140 from the folded state to the used state. Similarly, when the angle between the backrest 141 and the seat cushion 142 remains unchanged in the used state, when the trunk lid 110 switches from the second state to the first state, it drives the first gear 1261 to rotate in the opposite direction, which in turn drives the gear set meshing with the second gear 1262 to rotate in the opposite direction, thereby causing the corresponding pivot shaft 143 to rotate in the opposite direction to switch the seat 140 from the used state to the folded state.

[0145] In some embodiments, as shown in Figures 3 to 5, the gear set includes a plurality of second gears 1262, a third gear 1263, and a connecting frame (not shown). The second gears 1262 are planetary gears, the third gears 1263 have an internal gear ring, and the pivot shaft 143 is a gear shaft, i.e., a gear is formed on the outer periphery of the pivot shaft 143. The internal gear ring of the second gears 1262 meshes with the external gear ring of the pivot shaft 143. The internal gear ring of the third gear 1263 meshes with the plurality of second gears 1262 respectively, and the external gear ring of the third gear 1263 meshes with the first gear 1261. The plurality of second gears 1262 are connected by the connecting frame, and the connecting frame is connected to the luggage compartment cover 110.

[0146] It is understood that the pivot shaft 143, the second gear 1262, the third gear 1263, and the first gear 1261 mesh sequentially, thereby forming a planetary gear system between the pivot shaft 143, the second gear 1262, the third gear 1263, and the connecting frame. This ensures that the second linkage component experiences balanced force, resulting in more stable transmission and significantly improved user comfort. Of course, in some other embodiments, the gear shaft and the first gear 1261 can also be directly meshed to achieve synchronous switching between the states of the seat 140 and the trunk lid 110. This embodiment does not impose specific limitations on this.

[0147] In some embodiments, the angle between the backrest 141 and the seat cushion 142 is adjustable when in use.

[0148] Understandably, by making the angle between the backrest 141 and the seat cushion 142 adjustable, users can adjust it according to their own needs, thereby increasing the versatility and personalization of the seat 140.

[0149] In some embodiments, the gear set further includes an adjustment element (not shown) that controls the disengagement and engagement of the pivot shaft 143 with the second gear 1262, thereby adjusting the angle between the backrest 141 and the seat cushion 142.

[0150] Understandably, when the trunk lid 110 switches from the first state to the second state, the two ends of the adjusting component are connected to the trunk lid 110 and the connecting bracket respectively, thereby ensuring that the states of the seat 140 and the trunk lid 110 switch synchronously. After the trunk lid 110 is in the second state and the seat 140 is in use, the adjusting component and the connecting bracket are disengaged, thereby allowing the angle between the seat 140 and the backrest 141 to be freely adjusted while maintaining the second state. After the adjustment is completed, the adjusting component and the connecting bracket are reconnected so that the seat 140 can maintain the current angle.

[0151] This application also provides a luggage assembly.

[0152] As shown in Figure 1, the luggage assembly includes a luggage body, a tailgate sill 300, and the aforementioned vehicle support device 100. The luggage body forms a storage space 200 with an opening. The tailgate sill 300 is located at the opening of the storage space 200, and the top of the tailgate sill is higher than the bottom wall of the storage space 200. The luggage cover 110 of the vehicle support device 100 is disengaged from the tailgate sill 300 in a first state, and abuts against the tailgate sill 300 in a second state.

[0153] It should be noted that the trunk body can be formed from the vehicle body so that the storage space 200 can be connected to the passenger compartment of the vehicle. This embodiment does not impose specific restrictions on this.

[0154] Understandably, by having the trunk lid 110 abut against the rear door sill 300 in the second state, the trunk lid 110 can be maintained in the second state.

[0155] The luggage assembly provided according to the embodiments of this application ensures the storage function while improving the applicability and flexibility of the luggage assembly.

[0156] In some embodiments, the luggage assembly further includes a limiting structure disposed within the storage space 200. The luggage cover 110 abuts against the limiting structure in a first state and disengages from the limiting structure in a second state. The limiting structure includes, but is not limited to, horizontal ribs protruding from the left and right side walls of the storage space 200.

[0157] It is understandable that by having the trunk lid 110 abut against the limiting structure in the first state, the trunk lid 110 can be maintained in the first state.

[0158] In some embodiments, the luggage assembly also includes a rear hatch, which is closable and mounted on the luggage body and adapted to abut against a rear hatch sill 300 to close the storage space 200.

[0159] This application also provides a vehicle. As shown in FIG1, the vehicle includes the above-described luggage compartment assembly.

[0160] The vehicle provided according to the embodiments of this application ensures the storage function while improving the vehicle's applicability and flexibility, and enhancing its practicality and functionality.
