With the rise of outdoor travel, people not only need travel tools but also can rest at any time, so that the rear row seat can be flush with the trunk cover plate after being laid down. Generally, the height and angle of the trunk lid directly affect the convenience of taking and putting luggage and the stability of putting luggage, and are limited by the seat structure, and the rear seat back usually has a certain height difference with the trunk lid after being laid down.

Thus, to ensure that the seat back is flush with the cover plate after being laid down, there are two common solutions. The first solution is to intentionally lift the trunk lid to substantially align with the back of the seat when laid down, but such an arrangement would sacrifice trunk space and would be inconvenient for the user to access the luggage. The second scheme is to intentionally incline the spare tire cover plate, so that the front edge of the spare tire cover plate is lifted to ensure that the front edge of the spare tire cover plate is basically flush with the backrest surface of the laid back seat, but the spare tire cover plate is arranged to cause the storage in the trunk to be easy to topple, and the spare tire cover plate has poor practicability and potential safety hazards.

As shown in fig. 1 and 2, according to a first aspect of the present invention, there is provided a seat back and trunk lid linkage, which includes a seat back 1, a trunk lid 2 and a transmission 3.

In the following description, a specific structure of the above-described components of the linkage of the seat back and the trunk lid and a connection relationship of the above-described components will be specifically described with reference to fig. 1 and 2.

As shown in fig. 1 and 2, in the embodiment, the seat back 1 may include a design posture 11 and a lying posture 12, wherein the design posture 11 may be a state in which the seat back 1 stands during ordinary use. The seat back 1 can be turned from the design posture 11 to the first direction, and after it is turned in the first direction to the design limit position, the seat back 1 will be in the lying posture 12. Similarly, the seat back 1 can be turned in the second direction from the reclining position 12, and when it is turned in the second direction to the design limit position, the seat back 1 returns to the design position 11. Here, the first direction may be the front direction (left direction in fig. 1) of the seat back 1, i.e., the seat back 1 may be turned forward from the design posture 11 to the reclined posture 12, and the second direction may be the opposite direction of the first direction, i.e., the seat back 1 may be turned in the reverse direction of the original path to the design posture 11 in the reclined posture 12.

As shown in fig. 1 and 2, in the embodiment, the trunk lid 2 is connected to the seat back 1 through the transmission 3, and the movement of the seat back 1 can be transmitted to the trunk lid 2 through the transmission 3. Specifically, the trunk lid 2 may include a first posture 21 and a second posture 22, and the trunk lid 2 will be in the first posture 21 when the seat back 1 is in the design posture 11, and the trunk lid 2 will be in the second posture 22 when the seat back 1 is in the reclined posture 12. Specifically, the seat back 1 can drive the luggage compartment cover plate 2 to move through the transmission device 3, so that the first posture 21 of the luggage compartment cover plate 2 is synchronous with the design posture 11 of the seat back 1, the second posture 22 of the luggage compartment cover plate 2 is synchronous with the falling posture 12 of the seat back 1, and the seat back 1 in the falling posture 12 can be flush with the luggage compartment cover plate 2 in the second posture 22, so that the requirement that the seat back 1 can be flush with the luggage compartment cover plate 2 under the falling posture 12 is met, and the inconvenience in space and the unstable storage of articles caused by the inclination of the luggage compartment cover plate 2 in the second posture 22 in the common use process are avoided.

Preferably, as shown in fig. 1 and 2, in an embodiment, the seat back 1 may include a first side surface 101 and a second side surface 102. The first side surface 101 is a side surface of the seat back 1 for leaning against by a user (i.e. a front surface of the seat back 1) in the design posture 11, and the second side surface 102 is an opposite surface of the first side surface 101. Preferably, the second side surface 102 may be a flat surface, and with the seat back 1 in the reclined position 12, the second side surface 102 will be flush with the upper surface of the trunk lid 2, thereby forming a longer flat surface for the user to rest on his back.

Further, it is preferable that, as shown in fig. 1 and 2, in the embodiment, in the case where the seat back 1 is in the reclined posture 12, a plane which is constituted together with the upper surface of the trunk lid 2 is disposed obliquely with respect to the horizontal plane. That is, the second side surface 102 of the seat back 1 in the reclined position 12 and the upper surface of the trunk lid 2 in the second position 22 are not perfectly horizontal, and may form an acute angle with the horizontal plane. The trunk lid panel 2 in the first posture 21 may be set to be completely horizontal, so that the trunk lid panel 2 can be normally used without inconvenience for use when the seat back 1 is in the design posture 11.

Preferably, as shown in fig. 1 and 2, in an embodiment, the transmission 3 may include a first main shaft (not shown) and a second main shaft (not shown). The first main shaft may be connected to the seat back 1, and may be coaxial with a rotating shaft around which the seat back 1 is turned, so that the first main shaft can rotate synchronously with the seat back 1. A first gear (not shown) may be fixedly disposed on the first spindle, and a second gear (not shown) may be fixedly disposed on the second spindle, and the first gear and the second gear may be capable of cooperating with each other, so that the first spindle can drive the second spindle to rotate during the rotation process. The second spindle can then be connected to the luggage compartment flap 2, so that the seat back 1 can indirectly drive the luggage compartment flap 2 into motion during the tilting process, so that the first position 21 of the luggage compartment flap 2 is synchronized with the design position 11 of the seat back 1, and the second position 22 of the luggage compartment flap 2 is synchronized with the reclining position 12 of the seat back 1.

Specifically, as shown in fig. 1 and fig. 2, in an embodiment, a link 31 may be disposed on the second spindle, a first end of the link 31 may be fixed to the second spindle and rotate synchronously with the second spindle, and a second end of the link 31 may be clamped with the trunk lid 2. The trunk lid 2 may be a rectangular lid having a first end 201 connected to the second end of the linkage 31, and preferably, the first end 201 of the trunk lid 2 is the end adjacent to the seat back 1. During the rotation of the second main shaft, since the first end of the link 31 is fixed to the second main shaft, the second end of the link 31 will rotate around the second main shaft, and the first end 201 of the luggage cover 2 connected to the second end of the link 31 will be lifted upwards or lowered downwards. Preferably, the bottom of the trunk lid 2 may be formed with a slot, and the second end of the link 31 may be formed as a platform provided with a latch capable of cooperating with the slot, so that the first end 201 of the trunk lid 2 can be securely connected with the link 31 in the process of being lifted or lowered. The transmission 3 converts the axial movement of the seat back 1 into the required vertical movement of the luggage compartment lid 2, in particular, for example: the seat back 1 is turned 105 ° in the first direction and the first end 201 of the luggage compartment lid 2 is lifted upwards by 30mm, with the second side surface 102 of the seat back 1 just flush with the upper surface of the luggage compartment lid 2.

However, without being limited thereto, the structure of the link member is formed as just one preferred embodiment, and may be formed in other cases as long as the function of connecting the second main shaft and the first end of the trunk lid can be achieved.

Further, in an embodiment, preferably, the number of the link members 31 may be multiple, and the multiple link members 31 are arranged at intervals along the axial direction of the second spindle and are all connected to the second spindle and the first end 201 of the trunk lid plate 2, so that the trunk lid plate 2 is stressed more uniformly. Further, preferably, the diameter of the first gear may be smaller than that of the second gear, and since the stroke of the seat back 1 is larger than that of the trunk lid plate 2, the first gear as a driving gear may be provided as a small gear, and the second gear as a driven gear may be provided as a large gear, to convert a large circumferential displacement of the seat back 1 into a small vertical displacement required for the trunk lid plate 2.

Furthermore, according to a second aspect of the present invention, there is provided a vehicle comprising a seat back and trunk lid linkage as described above.

In use, the seat back 1 is connected to the luggage compartment lid 2 via the transmission 3. In the case where the seat back 1 is turned from the design posture 11 to the first direction to the lying posture 12, the trunk lid 2 will be moved from the first posture 21 to the second posture 22 by the driving of the transmission 3, in which case the second side surface 102 of the seat back 1 is flush with the upper surface of the trunk lid 2 for the rest of the user; in the case where the seat back 1 is turned back to the design posture 11 from the reclining posture 12 in the second direction, the trunk lid 2 is driven by the transmission 3 to return to the first posture 21 from the second posture 22, and in this case, the trunk lid 2 is kept horizontal to avoid inconvenience in use of the trunk.

Finally, it should be noted that: the above-mentioned embodiments are only specific embodiments of the present application, and are used for illustrating the technical solutions of the present application, but not limiting the same, and the scope of the present application is not limited thereto, and although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still make modifications or changes to the embodiments described in the foregoing embodiments, or make equivalent substitutions for some features, within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the exemplary embodiments of the present application, and are intended to be covered by the scope of the present application.
