With reference to FIG. 1 and FIG. 2 , the present application provides a vehicle 100. The vehicle 100 includes a vehicle body 1 and a seat assembly 2. With reference to FIG. 3 , the seat assembly 2 of the present application includes a seat structure 21 and a connecting rod structure 22. The seat structure 21 includes a cushion portion 211 for passengers of the vehicle 100 to sit on. The connecting rod structure 22 includes a first end 221 and a second end 222. The first end 221 is pivotally connected to a side of the cushion portion 211 toward a fixed surface 211a thereof. The second end 222 is connected to the vehicle 100.

The seat assembly 2 can be switched between a use state and a stowed state. For the convenience of explanation, the first direction X, the second direction Y and the third direction Z are set as reference directions in the drawings of the present application. The first direction X, the second direction Y and the third direction Z can be at any angle. For the convenience of explanation, the embodiment shown in the drawings is presented as an example in which the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

When the connecting rod structure 22 of the seat assembly 2 of the present application pivots with the cushion portion 211, the distance between the first end 221 and the second end 222 in the first direction X changes to change the vertical distance between the fixed surface 211a and the second end 222. The seat assembly 2 of the embodiment shown in FIG3 is in use. The seat assembly 2 of the embodiment shown in FIG4 is in the stowed state. When the seat assembly 2 is switched from the use state to the stowed state, the distance between the first end 221 and the second end 222 in the first direction X increases, so that the vertical distance between the second end 222 and the fixed surface 211a becomes smaller, thereby achieving the descent of the seat assembly 2. When the seat assembly 2 is switched from the stowed state to the use state, the distance between the first end 221 and the second end 222 in the first direction X decreases, so that the distance between the second end 222 and the fixed surface 211a increases, thereby achieving the ascent of the seat.

In the embodiment shown in FIGS. 3 and 4 , the change in the vertical distance between the second end 222 and the fixing surface 211 a is reflected as a change in the distance between the second end 222 and the fixing surface 211 a in the third direction Z.

By such arrangement, the seat assembly 2 can change its state between when in use and when not in use. When the seat assembly 2 is not in use, the occupant can reduce the distance between the second end 222 and the cushion portion 211 through the connecting rod structure 22, thereby reducing the space occupied by the seat assembly 2 and facilitating the storage of the seat assembly 2. At the same time, the connecting rod structure 22 can support the seat structure 21, so that the seat assembly 2 does not need to rely on additional components of the vehicle 100 to achieve support when in use, and the structure is simple. In addition, the distance between the second end 222 and the cushion portion 211 in the third direction Z can be changed, so that the occupant can adjust the size of the seat assembly 2 in the third direction Z according to the required riding height.

The seat assembly 2 can actually be assembled at any position of the vehicle 100. For example, the seat assembly 2 can be assembled on the floor of the rear passenger space of the vehicle 100. Referring to Figures 1 and 2, the vehicle body 1 includes a luggage compartment 11, a tailgate (not shown) that closes the luggage compartment 11, and a floor 12 disposed in the luggage compartment 11. In some embodiments, the second end 222 of the seat assembly 2 is connected to the floor 12. In other words, in this embodiment, the seat assembly 2 is disposed in the luggage compartment 11. Among them, the connecting rod structure 22 includes a forward rotation state and a reverse rotation state: when the connecting rod structure 22 rotates forward, the connecting rod structure 22 drives the seat structure 21 to move away from the floor 12, so that the seat assembly 2 is in the state shown in Figures 1 and 2. When the connecting rod portion 223 is reversed, the connecting rod structure 22 drives the seat structure 21 to move closer to the floor 12, so that the seat assembly 2 is in the state shown in Figures 4 or 5.

This embodiment makes the seat assembly 2 not occupy the riding space of the vehicle 100. When the occupants are engaged in outdoor activities such as camping, the seat assembly 2 can be raised by rotating the connecting rod structure 22 forward, so that the occupants can sit on the seat assembly 2 in the luggage compartment 11. When the occupants do not need to use the seat assembly 2, the occupants can store the seat assembly 2 by reversing the connecting rod structure 22. There is enough space in the luggage compartment 11 to accommodate occupants of different heights and body shapes. At the same time, when the tailgate is opened, the occupants can look outside the vehicle 100 when sitting in the luggage compartment 11, which expands the field of vision and provides a better experience.

Since the connecting rod structure 22 of the seat assembly 2 can realize the lifting and lowering of the seat structure 21 in the third direction Z, when the seat assembly 2 of the present application is assembled in the luggage compartment 11, even if there is a threshold of a tailgate at the rear of the vehicle 100, the seat structure 21 can extend out of the luggage compartment 11 by changing its position in the third direction Z. It can be seen that the seat assembly 2 of the present application can be adapted to vehicles 100 of different tailgate types, and is not limited to vehicles 100 whose tailgate is a floor door.

As shown in FIG. 1 , in an optional embodiment, the bottom plate 12 includes a receiving groove 121. The second end 222 is disposed in the receiving groove 121. When the connecting rod structure 22 is reversed to the extreme position, the seat assembly 2 is accommodated in the receiving groove 121. By providing the receiving groove 121, when the seat assembly 2 is in the stowed state, the seat assembly 2 can be retracted into the receiving groove 121, and the space occupied by the luggage compartment 11 in the third direction Z is reduced. The provision of the receiving groove 121 can prevent the seat assembly 2 from occupying the storage space of the luggage compartment 11 when not in use. It should be noted that when the connecting rod structure 22 is reversed to the extreme position, the seat assembly 2 may be only partially accommodated in the receiving groove 121, that is, there is still a part of the seat assembly 2 protruding from the bottom plate 12. Alternatively, the seat assembly 2 may be completely accommodated in the receiving groove 121, thereby further reducing the sense of presence in the stowed state.

In the embodiment shown in FIG. 1 and FIG. 2 , the vehicle body 1 further includes a cover plate 13. The cover plate 13 is detachably connected to the bottom plate 12 and is used to cover or expose the receiving groove 121. The provision of the cover plate 13 can improve the flatness of the bottom plate 12, thereby facilitating the passengers to place items in the luggage compartment 11. In addition, the cover plate 13 covering the receiving groove 121 can also prevent items from accidentally falling into the receiving groove 121, or children's limbs from being trapped between the receiving groove 121 and the seat assembly 2, causing danger.

There are many possible ways to connect the link structure 22 to the vehicle 100 .

As shown in FIG. 2 and FIG. 5 , in some embodiments, the seat assembly 2 includes a first slide rail 23 extending along a first direction X. The first slide rail 23 is disposed on the cushion portion 211. The first end 221 is slidably connected to the first slide rail 23. In other words, the first end 221 can slide in the first slide rail 23, thereby changing its position in the first direction X. By providing the first slide rail 23, the first end 221 can be slidably connected to the cushion portion 211, reducing sliding friction, which is beneficial to improving the movement smoothness of the connecting rod structure 22 and reducing friction noise.

In this embodiment, the second end 222 may be pivotally connected to the vehicle 100 at a fixed position. In other words, the position of the second end 222 in the first direction X remains unchanged, and the connecting rod structure 22 changes the distance between the first end 221 and the second end 222 by changing the position of the first end 221 in the first direction X.

Alternatively, the vehicle 100 may also be provided with a slide rail extending along the first direction X, and the slide rail is slidably connected to the second end 222. Then, the position of the second end 222 in the first direction X can be changed. When the seat assembly 2 switches between the stowed state and the use state, the first end 221 and the second end 222 can move synchronously in the first direction X. In this way, the connecting rod structure 22 can efficiently drive the position change of the seat structure 21 in the third direction Z, reducing the length setting requirement of the first slide rail 23.

In some embodiments, the seat assembly 2 also includes a fixing portion 24 fixedly connected to the vehicle 100. The first slide rail 23 is also disposed in the fixing portion 24, and the second end 222 is slidably connected to the first slide rail 23. By disposing the first slide rail 23 in the fixing portion 24, the seat assembly 2 can improve the degree of integration. When assembling the vehicle 100, the manufacturer does not need to design a slide rail for the vehicle 100 or design a pivot structure of the second end 222. The manufacturer only needs to directly assemble the seat assembly 2 with the fixing portion 24 to the vehicle 100. At the same time, as described above, the simultaneous movement of the first end 221 and the second end 222 can increase the position change speed of the seat structure 21 in the third direction Z and reduce the length setting requirement of the first slide rail 23.

Of course, in other embodiments, the connecting rod structure 22 may also have a first end 221 pivotally connected to the cushion portion 211, and the position in the first direction X remains unchanged. At the same time, the second end 222 is slidably connected to the first slide rail 23 of the fixing portion 24, or is slidably connected to the slide rail of the bottom plate 12. The present application does not limit this.

To further improve the adjustability of the seat assembly 2, as shown in FIGS. 5 and 6, in some embodiments, the cushion portion 211 includes a cushion body 2111 and a connecting plate 2112 that are stacked. The first end 221 is pivotally connected to a side of the connecting plate 2112 away from the cushion body 2111. The seat assembly 2 also includes a second slide rail 25 extending along the second direction Y. The second slide rail 25 is disposed on a side of the connecting plate 2112 that faces the cushion body 2111, and the cushion body 2111 is slidably connected to the second slide rail 25. By such an arrangement, the position of the seat structure 21 in the second direction Y is adjustable. In an embodiment where the seat assembly 2 is assembled in the luggage compartment 11, the seat structure 21 can protrude from the luggage compartment 11 in the second direction Y, thereby expanding the field of vision of the occupant of the seat assembly 2.

It should be noted that, in this embodiment, the fixing surface 211a is disposed on a side of the connecting plate 2112 away from the cushion body 2111, and the first end 221 is pivotally connected to a side of the cushion portion 211 facing the fixing surface 211a. In addition, the first end 221 may be pivotally connected to the cushion portion 211 directly to the fixing surface 211a, or may be pivotally connected to the fixing surface 211a indirectly through the first slide rail 23, and the present application does not limit this.

In order to enable the seat structure 21 to extend as far as possible out of the luggage compartment 11 while maintaining the riding stability of the occupant, in some embodiments, the cushion portion 211 can move in the second direction Y beyond the luggage compartment 11 by a distance greater than or equal to 190 mm and less than or equal to 210 mm.

In an optional embodiment, the seat structure 21 includes a backrest 212. The backrest 212 is pivotally connected to the cushion portion 211. The backrest includes a leaning surface 212a. The cushion portion 211 includes a sitting surface 211b opposite to the fixed surface 211a. When the occupant sits on the seat assembly 2, he or she can sit on the sitting surface 211b and lean his or her back against the leaning surface 212a.

The seat structure 21 of this embodiment includes an open state and a folded state:

When the seat structure 21 is in the open state, the leaning surface 212a and the sitting surface 211b extend in different directions, i.e., the state shown in FIG6 . At this time, there is an angle α between the cushion portion 211 and the backrest portion 212, which can be, for example, 100°, 105°, 110°, 115°, 120° or any angle therebetween. This angle range can effectively ensure the comfort of the occupant when leaning on the backrest portion 212.

When the seat structure 21 is in the folded state, the leaning surface 212a and the sitting surface 211b are parallel and opposite to each other, that is, the state shown in Fig. 5. The leaning surface 212a and the sitting surface 211b are parallel, which can reduce the thickness of the seat structure 21 in the third direction Z when it is in the folded state, which is conducive to miniaturization and storage of the seat assembly 2.

The arrangement of the backrest portion 212 enables the passenger to lean on the leaning surface 212a when sitting on the seat assembly 2, further improving the riding comfort of the seat assembly 2. At the same time, the backrest portion 212 and the cushion portion 211 are pivotally connected, improving the integrity of the seat assembly 2. When the seat assembly 2 is in the storage state, the backrest portion 212 and the cushion portion 211 can be stored simultaneously in, for example, the receiving groove 121. Therefore, the passenger does not need to find a separate storage place for the backrest portion 212.

Referring to FIGS. 3 to 6 , in some embodiments, the connecting rod structure 22 includes a connecting rod portion 223. The first end 221 and the second end 222 are respectively disposed at the two ends of the connecting rod portion 223. The number of the connecting rod portions 223 includes two, namely, a first connecting rod 223a and a second connecting rod 223b. The first connecting rod 223a and the second connecting rod 223b are pivotally connected at a pivot point 223c. The pivot point 223c is located at the non-ends of the first connecting rod 223a and the second connecting rod 223b. In other words, in this embodiment, the connecting rod portion 223 is configured as an "X"-shaped cross structure. By configuring the first connecting rod 223a and the second connecting rod 223b, the connecting structure supports the two ends of the seat structure 21 in the first direction X, which can effectively improve the stability of the seat structure 21.

It should be noted that, in the embodiment shown in FIG. 3 , the pivot point 223c is located at the midpoint of the first link 223a and the second link 223b, thereby reducing the size of the link structure 22 in the first direction X. In other embodiments, the pivot point 223c may be disposed close to the first end 221, or close to the second end 222. The present application is not limited thereto.

The number of the connecting rod portion 223 can be only one, and it is arranged at the midpoint of the seat structure 21 in the second direction Y, so as to improve the stability of the seat assembly 2. Alternatively, as shown in FIG6 , the connecting rod structure 22 includes a plurality of connecting rod structures 22. The plurality of connecting rod structures 22 are arranged at intervals along the second direction Y. The arrangement of the plurality of connecting rod structures 22 can improve the supporting stability of the connecting rod structure 22 on the seat structure 21, and prevent the seat structure 21 from rotating around an axis parallel to the first direction X. At the same time, the plurality of connecting rod structures 22 simultaneously support the seat structure 21, so this embodiment reduces the material strength and structural strength requirements of the connecting rod structure 22, and effectively reduces the volume and material cost of the connecting rod structure 22.

In this embodiment, as shown in FIG. 2 , the fixing portion 24 is configured as a square frame extending along the first direction X and the second direction Y, so that the two connecting rod structures 22 distributed along the second direction Y can slide in cooperation with the first slide rail 23 provided on the fixing portion 24. At the same time, the fixing portion 24 distributed along the second direction Y can improve the structural stability of the second end 222 of the connecting rod structure 22.

Of course, in other embodiments, the connecting rod structure 22 may be provided with multiple connecting rods. The multiple connecting rods are arranged at intervals in the second direction Y. In addition, on a plane perpendicular to the second direction Y, the multiple connecting rods are crossed in an "X" shape. This embodiment can also achieve position adjustment of the seat structure 21 in the third direction Z. This application is not limited to this.

In the above-mentioned embodiments, the movement of the connecting rod structure 22 can be adjusted manually, and then the position of the connecting rod structure 22 can be locked by an additional locking structure. Alternatively, the first slide rail 23 can be provided with a plurality of latches spaced apart along the first direction X, and the first end 221 or the second end 222 that cooperates therewith is correspondingly provided with a latch. Through the cooperation of the latches and the latches, the seat assembly 2 can achieve multi-level height adjustment.

In an optional embodiment, the movement of the connecting rod structure 22 can be automatically achieved by a mechanical structure. In this embodiment, the seat assembly 2 also includes a driving structure 26. The driving structure 26 is connected to the connecting rod structure 22 to drive the connecting rod structure 22 to pivot with the cushion portion 211. For example, as shown in Figures 3 and 4, the driving structure 26 can be a retractable hydraulic rod. The driving structure 26 reduces the distance between the first end 221 and the second end 222 by pushing the connecting rod structure 22 away from the fixing portion 24, and increases the distance between the second end 222 and the first end 221 by pulling the connecting rod structure 22 close to the fixing portion 24. It should be noted that in an embodiment where the fixing portion 24 is not provided, the driving structure 26 can be provided on the vehicle 100 or on the fixing surface 211a. This application is not limited to this.

In an embodiment where the position of the second end 222 in the first direction X is fixed, the driving structure 26 may also be a motor disposed at the second end 222. The driving structure 26 achieves position adjustment of the seat assembly 2 by driving the link structure 22 to pivot at the second end 222.

The specific embodiments described herein are merely examples of the spirit of the present application. A person skilled in the art of the present application may make various modifications, supplements, or replace the specific embodiments described, but this will not deviate from the spirit of the present application or exceed the scope defined by the attached claims.

The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
