[0045] Please see Figures 1 to 23This utility model provides a vehicle seat 100 and a vehicle. By changing the relative position between the movable seat cushion part 120 and the fixed seat cushion part 110, the seat cushion 100 can expand the seat cushion area. In turn, the posture of the vehicle seat 100 can be adjusted by expanding the seat cushion area, thereby improving the flexibility of the posture adjustment of the vehicle seat 100 and enriching the use functions of the vehicle seat 100.

[0046] Please see Figure 1 and Figure 2 The vehicle seat 100 provided by this utility model includes: a fixed seat cushion portion 110, a backrest 130, and a movable seat cushion portion 120. The fixed seat cushion portion 110 is installed on the vehicle floor. Specifically, the fixed seat cushion portion 110 has a mounting portion 111 for connecting to the vehicle on the side facing the vehicle floor. When the vehicle seat 100 is installed inside the vehicle body, the fixed seat cushion portion 110 is fixedly connected to the vehicle floor through the mounting portion 111. The fixed connection method can be bolted connection, snap-fit ​​connection, or riveted connection, etc. The backrest 130 is used for passengers to lean against. The backrest 130 is connected to the rear-facing end of the fixed seat cushion portion 110. The connection method can be a fixed connection or a rotatable connection. The specific connection structure between the backrest 130 and the fixed seat cushion portion 110 can refer to the connection structure between the backrest 130 and the seat cushion portion in the prior art, and will not be described again here.

[0047] Please see Figures 1 to 4 The movable seat cushion 120 is connected to the fixed seat cushion 110 on the side facing the front of the vehicle. The movable seat cushion 120 has a first position and a second position relative to the fixed seat cushion 110, and slides between the first and second positions. The sliding method is not limited. In one embodiment, a linkage mechanism can be provided between the movable seat cushion 120 and the fixed seat cushion 110. By manually moving the movable seat cushion 120, the linkage moves, thereby causing the movable seat cushion 120 to slide between the first and second positions. In another embodiment, a linkage mechanism can also be provided between the movable seat cushion 120 and the fixed seat cushion 110. The linkage mechanism is driven automatically by a power source such as a cylinder or motor to cause the movable seat cushion 120 to slide between the first and second positions. In other embodiments, two sets of linear movement mechanisms may be provided between the movable seat cushion portion 120 and the fixed seat cushion portion 110. One set of linear movement mechanisms enables the movable seat cushion portion 120 to slide relative to the fixed seat cushion portion 110 in the horizontal direction, and the other set of linear movement mechanisms enables the movable seat cushion portion 120 to slide relative to the fixed seat cushion portion 110 in the vertical direction.

[0048] Please see Figure 1 and Figure 5In the first position, the movable seat cushion portion 120 covers the fixed seat cushion portion 110, meaning the movable seat cushion portion 120 is at least partially located above the fixed seat cushion portion 110, forming a first posture of the vehicle seat 100. In the first posture, the vehicle seat 100 has a first seat cushion seating area. The movable seat cushion portion 120 may completely cover the upper surface of the fixed seat cushion portion 110, or it may partially cover the upper surface of the fixed seat cushion portion 110. In the first posture of the vehicle seat 100, the movable seat cushion portion 120 and the fixed seat cushion portion 110 combine to form a conventional seat cushion structure, allowing passengers to maintain a normal sitting posture. Optionally, in this embodiment, in the first position, the movable seat cushion portion 120 completely covers the upper surface of the fixed seat cushion portion 110, meaning the upper surface of the movable seat cushion portion 120 forms the first seat cushion seating area. This arrangement facilitates the formation of a comfortable and flat seat cushion surface on the upper surface of the movable seat cushion portion 120, ensuring the comfort of the vehicle seat 100.

[0049] Please see Figures 2 to 4 In the second position, the movable seat cushion portion 120 moves away from the backrest 130 to the side away from the fixed seat cushion portion 110, and rotates downwards on the side close to the fixed seat cushion portion 110, so that the movable seat cushion portion 120 and the fixed seat cushion portion 110 align on the side away from the backrest 130, thereby lengthening the fixed seat cushion portion 110 and forming the second posture of the vehicle seat 100. In the second posture, the vehicle seat 100 has a second seat cushion seating area. When the movable seat cushion portion 120 aligns with the fixed seat cushion portion 110, the upper surface of the movable seat cushion portion 120 may be flush with the upper surface of the fixed seat cushion portion 110 or may not be flush. Preferably, in this embodiment, when the movable seat cushion portion 120 aligns with the fixed seat cushion portion 110, the upper surface of the movable seat cushion portion 120 aligns with the upper surface of the fixed seat cushion portion 110. This creates a flat connecting surface between the movable seat cushion portion 120 and the fixed seat cushion portion 110, ensuring the comfort requirements of the vehicle seat. In the second posture, the upper surface of the movable seat cushion 120 is flush with the upper surface of the fixed seat cushion 110 to form a second seat cushion seating area, and the second seat cushion seating area is larger than the first seat cushion seating area.

[0050] In this embodiment, by sliding the movable seat cushion 120 between the first and second positions, different combinations between the movable seat cushion 120 and the fixed seat cushion 110 can be achieved, thereby enabling the vehicle seat 100 to switch between the first and second postures. Since the seating area of ​​the first seat cushion is smaller than that of the second seat cushion, when the vehicle seat 100 switches from the first posture to the second posture, the seating area of ​​the seat cushion can be expanded. This expansion of the seating area allows for adjustment of the posture of the vehicle seat 100, thereby improving the flexibility of posture adjustment and enriching the functionality of the vehicle seat 100. Simultaneously, since the backrest 130 does not need to be flipped or tilted during the posture adjustment of the vehicle seat 100 and can maintain a relatively fixed position relative to the surrounding components, no additional adjustment space needs to be reserved around the backrest, thus improving the utilization rate of the interior space.

[0051] It should be noted that, in the embodiments of this application, both the movable seat cushion portion 120 and the fixed seat cushion portion 110 include a frame portion and a soft pad portion, with the soft pad portion covering the outside of the frame portion. The specific arrangement structure between the soft pad portion and the frame portion can refer to the arrangement structure between the soft pad portion and the frame portion of the seat cushion in the existing vehicle seat 100, and will not be repeated here.

[0052] To improve the stability of the flush engagement between the movable seat cushion 120 and the fixed seat cushion 110 when the movable seat cushion 120 is in the second position, optionally, please refer to Figure 5 and Figure 7 In one embodiment of this utility model, the end of the movable seat cushion 120 near the backrest 130 is movably connected to the fixed seat cushion 110 via a sliding structure 140. The sliding structure 140 can be any structure capable of enabling the movable seat cushion 120 to slide between a first position and a second position, such as a crank-slider structure, a spherical four-bar structure, or a slanted crank-rocker structure. The end of the movable seat cushion 120 away from the backrest 130 is provided with a support portion 121, which supports the vehicle body in the second position. The support portion 121 can be fixedly connected to the movable seat cushion 120, or it can be rotatably connected to the movable seat cushion 120. For example, the support portion 121 can have two states: folded and unfolded. In the first position, the support portion 121 remains folded to facilitate the movable seat cushion 120 covering the fixed seat cushion 110. In the second position, the support portion 121 unfolds to support the movable seat cushion 120. Optionally, in this embodiment, the support portion 121 is fixedly connected to the movable seat cushion portion 120. This simplifies the structure of the support portion 121, reduces the number of steps required to adjust the posture of the vehicle seat 100, and facilitates adjustment.

[0053] With this configuration, when the movable seat cushion 120 is in the second position, the end of the movable seat cushion 120 near the backrest 130 can be connected to the fixed seat cushion 110 through the sliding structure 140, and the end of the movable seat cushion 120 away from the backrest 130 can be supported on the vehicle floor below through the support part 121, thereby improving the under-support effect of the movable seat cushion 120 and thus improving the stability of the flush connection between the movable seat cushion 120 and the fixed seat cushion 110.

[0054] Please see Figure 2 and Figure 4 In one embodiment of this utility model, the movable seat cushion portion 120 has a groove 122 on the side facing the backrest 130. The shape of the groove 122 matches the shape of the fixed seat cushion portion 110, the height of the groove 122 is consistent with the height of the fixed seat cushion portion 110, and the width of the groove 122 is consistent with the width of the fixed seat cushion portion 110. In the first position, the fixed seat cushion is accommodated in the groove 122. Because the groove 122 is provided, and the shape of the groove 122 matches the shape of the fixed seat cushion portion 110, this arrangement allows the groove 122 to play a positioning role when the movable seat cushion portion 120 slides from the second position to the first position, thereby improving the repeatability of the movable seat cushion portion 120 in the first position and ensuring the overall aesthetics of the vehicle seat 100. At the same time, since the fixed seat cushion can be accommodated in the groove 122 in the first position, the overall structural design of the vehicle seat 100 can be made more compact, and the aesthetic performance can also be further improved.

[0055] To satisfy the requirement that the movable seat cushion portion 120 slides relative to the fixed seat cushion portion 110, the embodiment of this application does not specifically limit the location of the sliding structure 140. For example, the sliding structure 140 can be located in the center area of ​​the vehicle seat 100 in the width direction, or it can be located on both sides of the vehicle seat 100 in the width direction. Optionally, please refer to... Figure 10In one embodiment of this utility model, the sliding structure 140 includes two sets of sliding components 141, which are respectively disposed on both sides of the width direction of the vehicle seat 100. The two sets of sliding components 141 can be symmetrically disposed on both sides of the width direction of the vehicle seat 100, or they can be asymmetrically disposed, specifically to meet the sliding requirements of the movable seat cushion 120 between the first and second positions. Preferably, in this embodiment, the two sets of sliding components 141 are symmetrically disposed on both sides of the width direction of the vehicle seat 100, which facilitates the synchronous operation of the sliding components 141 on both sides and reduces the probability of jamming or tilting during the sliding of the movable seat cushion 120. By providing a set of sliding components 141 on each side of the width direction of the vehicle seat 100, the stability of the sliding connection between the movable seat cushion 120 and the fixed seat cushion 110 can be improved, and the connection support strength at the mating position between the movable seat cushion 120 and the fixed seat cushion 110 can also be improved when the movable seat cushion 120 is in the second position.

[0056] Please see Figures 7 to 9 In one embodiment of this utility model, the sliding assembly 141 includes a connecting rod 1411 and a guide member 1412. The guide member 1412 is fixedly connected to the vehicle floor via a mounting bracket 150. Specifically, one end of the mounting bracket 150 is fixedly connected to the vehicle floor, and the other end of the mounting bracket 150 is fixedly connected to the guide member 1412, thereby achieving fixation between the guide member 1412 and the vehicle floor. The fixing connection between the mounting bracket 150 and the vehicle floor and the guide member 1412 can be a bolt fixing connection, a snap-fit ​​connection, or a rivet fixing connection, etc. The mounting bracket 150 can be an integral bracket structure or a plurality of bracket units 151 spaced apart along the length direction of the guide member 1412. In this embodiment, each guide member 1412 corresponds to two bracket units 151, and the two bracket units 151 are respectively arranged at both ends of the length direction of the guide member 1412. It should be noted that in other embodiments, the guide member 1412 can also be fixedly connected to the fixed seat cushion portion 110. For example, the mounting bracket 150 can be fixedly connected to the fixed seat cushion portion 110 at one end and to the guide member 1412 at the other end, which can also meet the installation requirements of the guide member 1412.

[0057] Please see Figure 11 and Figure 15The connecting rod 1411 includes a rod body 1413, a first rotating part 1414, and a second rotating part 1415. The first rotating part 1414 and the second rotating part 1415 are rotatably connected to both ends of the rod body 1413 along its length. The first rotating part 1414 and the second rotating part 1415 can be rotatably connected to the rod body 1413 through a shaft hole fit, or they can be rotatably connected to the rod body 1413 through a slewing bearing. Optionally, in this embodiment, both the first rotating part 1414 and the second rotating part 1415 are rotatably connected to the rod body 1413 through a shaft hole fit. Specifically, one end of the first rotating part 1414 is rotatably connected to one end of the rod body 1413 along its length, and the other end of the first rotating part 1414 is fixedly connected to the movable seat cushion 120. To improve the connection strength between the first rotating part 1414 and the movable seat cushion part 120, optionally in this embodiment, a connecting block 123 is embedded in the movable seat cushion part 120, and the first rotating part 1414 is fixedly connected to the connecting block 123 to achieve a fixed connection with the movable seat cushion part 120. The fixed connection method can be a threaded fixed connection, a snap-fit ​​fixed connection, etc. In this embodiment, the connecting block 123 and the first rotating part 1414 are fixedly connected by tightening with threads.

[0058] Please see Figure 8 and Figure 11 One end of the second rotating part 1415 is rotatably connected to the other end of the rod part 1413 along its length, and the other end of the second rotating part 1415 is slidably connected to the guide member 1412. The specific structure of the slidable connection between the second rotating part 1415 and the guide member 1412 can be varied. For example, the guide member 1412 can be a sliding rod, and the second rotating part 1415 is provided with a sliding sleeve. The sliding between the second rotating part 1415 and the guide member 1412 is achieved by the sliding of the sliding sleeve on the sliding rod. Alternatively, the guide member 1412 can be a sliding groove, and the second rotating part 1415 is provided with a slider. The sliding between the second rotating part 1415 and the guide member 1412 is achieved by the sliding of the slider within the sliding groove. By setting the connecting rod 1411 and the guide member 1412, the movable seat cushion part 120 can slide relative to the fixed seat cushion part 110 between a first position and a second position. Furthermore, the sliding assembly 141 has a simple structure and low production cost.

[0059] Please see Figure 8 , Figure 11 , Figure 13 and Figure 15In one embodiment of this utility model, a long groove 14131 is provided at one end of the rod body 1413 near the first rotating part 1414. The long groove 14131 extends along the length direction of the rod body 1413. The first rotating part 1414 is slidably installed in the long groove 14131 and can rotate within the long groove 14131. Specifically, a cavity structure 14132 is provided at one end of the rod body 1413 near the first rotating part 1414. Long grooves 14131 are machined through the opposite walls on both sides of the cavity structure 14132. The first rotating part 1414 is a rotary shaft structure. Both ends of the first rotating part 1414 are respectively inserted into the long groove 14131. One end extends to the outside of one side of the long groove 14131 and is threadedly connected to the connecting block 123. The other end extends to the outside of the other side of the long groove 14131 and is provided with a stop pin 1417 at the end. The middle region of the first rotating part 1414 is located inside the cavity structure 14132, and a stop part 1418 is provided in the middle region. The two ends of the stop part 1418 stop on the inner side of the elongated grooves 14131 on both sides. This arrangement can realize the axial positioning of the first rotating part 1414 relative to the rod part 1413, and reduce the probability of tilting and jamming between the first rotating part 1414 and the rod part 1413 during the rotation process.

[0060] By providing an elongated groove 14131 on the rod body 1413 and slidably mounting the first rotating part 1414 within the elongated groove 14131, when the movable seat 120 is in the first position, the sliding of the first rotating part 1414 within the elongated groove 14131 ensures effective contact between the movable seat 120 and the fixed seat 110 in the height direction, thereby improving the support stability of the movable seat 120 in the first position. At the same time, it also reduces the contact force between the first rotating part 1414 and the rod body 1413, which is beneficial to improving the stress conditions at the position of the first rotating part 1414.

[0061] Although there are various options for the sliding method between the guide member 1412 and the second rotating part 1415, it is preferable to refer to [the following text is missing from the original] Figure 8 and Figure 11 In one embodiment of this utility model, the guide member 1412 is provided with a groove 14121, the extension direction of which is consistent with the length direction of the guide member 1412. The forming method of the groove 14121 on the guide member 1412 is not limited. For example, when the guide member 1412 is a channel steel, I-beam, or other profile, the groove 14121 can be a groove structure inherent in the profile itself, or it can be formed by further processing the existing groove structure. The cross-section of the groove 14121 can be a rectangular cross-section, a U-shaped cross-section, an arc-shaped cross-section, etc. Optionally, in this embodiment, the cross-section of the groove 14121 is an approximately rectangular cross-section. Please refer to the figure. Figure 11 , Figure 13 and Figure 15 One end of the second rotating part 1415 is rotatably connected to the rod part 1413, and the other end of the second rotating part 1415 is fixedly connected to a slider 1416. The slider 1416 can be integrally formed with the second rotating part 1415 or fixedly connected by bolts. Optionally, in this embodiment, the slider 1416 and the second rotating part 1415 are integrally formed. The slider 1416 is slidably connected in the groove 14121, and the cross-section of the slider 1416 matches the cross-sectional shape of the groove 14121, that is, the cross-section of the slider 1416 is rectangular. With this configuration, when the slider 1416 slides in the groove 14121, a larger contact area can be formed, making the slider 1416 slide more stably in the groove 14121 and less prone to tilting. In this embodiment, by setting the groove 14121 and the slider 1416, a sliding connection between the connecting rod 1411 and the guide member 1412 can be realized, and the structure is simple, easy to implement, and has low manufacturing cost.

[0062] This utility model also provides a vehicle, which includes a body and the vehicle seat 100 described in the above embodiments, the vehicle seat 100 being mounted on the vehicle body. The vehicle seat 100 can be a front seat 300 or a rear seat 400. The vehicle seat 100 can be a single seat, or a two-seater or three-seater, etc.

[0063] Please see Figure 23 In one embodiment of this utility model, the vehicle seat 100 is the rear seat 400 of the vehicle, and the vehicle seat 100 has multiple seating positions. When the movable seat cushion slides from the first position to the second position, the vehicle seat 100 can be transformed into a bed structure, allowing passengers to rest and take a nap more comfortably. Currently, the seat-to-bed technology on the market mainly focuses on using the flipping and flattening of the seat back to achieve the concept of a bed. In this embodiment, the bed-to-bed method does not require the backrest 130 of the vehicle seat 100 to be flipped. It only requires sliding the movable seat cushion 120 to the second position and filling the aisle space 500 in front of the vehicle seat 100 to achieve the bed posture. It does not occupy the driving area of ​​the front seat 300, and the bed-to-bed operation is simpler and more convenient. At the same time, since the backrest 130 does not need to be flipped, it will not interfere with the trunk or the front seats. Therefore, it does not require changing the installation position of other peripheral components in the vehicle, and the storage space of the vehicle trunk can be preserved. Furthermore, since the movable seat cushion 120 can be flush with the fixed seat cushion 110 when in the second position, the flatness of the bed is better, ensuring both sitting and lying comfort, without the need for an additional mattress.

[0064] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The vehicle interior features an interior trim panel 200 that covers the sliding components 141 on both sides of the vehicle seat 100 in the width direction. Specifically, the interior trim panel 200 covers the sliding structure 140 mounted on the vehicle seat 100. On each side of the vehicle seat 100, near the C-pillar structure on either side of the vehicle body, the lower trim panel corresponding to each C-pillar structure covers the sliding component 141 at the corresponding location. This arrangement not only provides better protection for the sliding structure 140 of the vehicle seat 100, reducing the probability of accidental contact, but also improves the aesthetics of the vehicle seat 100 mounted on the vehicle body.

[0065] The vehicle seat provided by this utility model allows for adjustment between different postures simply by changing the position of the movable seat cushion relative to the fixed seat cushion. Since the backrest does not need to be flipped or tilted during posture adjustment and can maintain a relatively fixed position relative to surrounding components, no additional adjustment space is required around the backrest, thus improving the utilization of interior space. Furthermore, because the first and second positions of the movable seat cushion are arranged along the length of the vehicle body, the movement of the movable seat cushion can be achieved by filling or avoiding the aisle space in front of the seat when it is installed in the vehicle. Therefore, the movement of the movable seat cushion does not occupy additional space for other components in the vehicle, further improving the utilization of interior space. Thus, this utility model effectively overcomes some practical problems in the prior art and has high utilization value and significance.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
