Description

Seat framework platform, automobile seat and automobile

Technical Field

The embodiment of the application relates to the technical field of automobile manufacturing, in particular to a seat framework platform, an automobile seat and an automobile.

Background

The H point (point) is usually the design reference point of the car seat, and the vertical distance from the H point to the lower bottom surface of the slide rail, i.e. the Block value, is an important indicator for characterizing the seat space, which directly affects the sitting height of the passenger and the arrangement space below the seat pan. In order to meet the design requirements of part of vehicle types, particularly pure electric vehicles, more structures or functional modules are configured below the seats, so that the seats of the vehicle types are expected to have lower Block values, and the design requirements of the whole vehicle are met.

The traditional automobile seat framework is generally composed of front and rear transverse pipes, left and right side plates, a connecting rod mechanism, sliding rails and other main components, wherein the sliding rails are generally arranged below the connecting rod mechanism, and the above seats are limited by the structures of the sliding rails, so that the Block value is difficult to be reduced to an ideal interval; in addition, some automobile seats are structurally changed too much, so that the structural design is complex, and the research and development cost of the whole automobile is greatly increased.

Disclosure of Invention

In view of the above, the embodiment of the application provides a seat framework platform, an automobile seat and an automobile, which have the advantages of simple structure and low research and development cost.

In a first aspect, an embodiment of the present application provides a seat frame platform including a base, a seat frame, and a linkage. The base is fixedly connected to the vehicle body bottom plate, a base is connected to the base, and the base can move relative to the base; the seat frame is formed by two cross bars and two seat frame side plates in a surrounding way and is arranged above the base for installing the seat basin; the upper end of the connecting rod mechanism is connected with the seat frame side plate, and the lower end of the connecting rod mechanism is connected with the base and used for adjusting the relative position of the seat frame and the base; at least one of the connecting rod mechanism and the seat frame side plate is arranged in a staggered manner with the orthographic projection of the base on the plane of the vehicle body bottom plate.

Specifically, the base station is fixedly connected with the vehicle body bottom plate, and a base capable of moving relative to the base station is connected to the base station. The specific implementation form of the base movable relative to the base is not limited, for example, the base is a one-dimensional linear guide rail, the base is a slider slidably connected to the linear guide rail, the slider may be slidably connected to the linear guide rail, and for example, a roller is provided on a side of the base adjacent to the base to move the base relative to the base, so that the seat frame platform connected to the base can move relative to the floor of the vehicle body. The seat frame is formed by two cross bars and two seat frame side plates in a surrounding way and is arranged above the base for installing the seat basin; in addition, the upper end of the connecting rod mechanism is connected with the seat frame side plate, and the lower end of the connecting rod mechanism is connected with the base and used for adjusting the relative position of the seat frame and the base station. Here, the connection form of the upper end of the link mechanism and the seat frame side plate and the connection form of the lower end of the link mechanism and the base are not limited, and preferably, a hinged connection form can be adopted, so that the stability is strong and the steering is flexible.

The vertical height of the seat frame and the vehicle body bottom plate can be reduced in a mode that at least one of the connecting rod mechanism and the seat frame side plate is in orthographic projection on the plane of the vehicle body bottom plate and orthographic projection of the base on the plane of the vehicle body bottom plate are staggered. Specifically, in the related art, since the base is disposed under the link mechanism or under the seat frame side plate, at this time, the vertical height of the base with respect to the floor normally located on the base is not changed, and in this case, when it is desired to move the link mechanism downward toward the floor to lower the height of the seat frame and the floor connected to the link mechanism, since the base has a blocking effect on the downward movement of the link mechanism under the link mechanism, it is difficult to achieve the lowering of the seat frame.

When the orthographic projection of the link mechanism on the plane of the automobile body bottom plate and the orthographic projection of the base on the plane of the automobile body bottom plate are staggered, namely, the link mechanism is arranged at the side position of the base, so that when the link mechanism is adjusted to move downwards relative to the automobile body bottom plate, the base is arranged at the side of the link mechanism, the link mechanism can be prevented from moving downwards relative to the automobile body bottom plate, and the height of a seat frame connected with the link mechanism relative to the automobile body bottom plate can be reduced, so that the design of a low sitting posture of a seat is realized. In addition, similarly, for example, the orthographic projection of the seat frame side plate on the plane of the vehicle body bottom plate and the orthographic projection of the base on the plane of the vehicle body bottom plate are staggered, compared with the situation that the base is positioned below the seat frame side plate in the related art, when the connecting rod mechanism and the seat frame side plate connected with the connecting rod mechanism are arranged in a downward moving mode, the base is not positioned below the seat frame side plate, and therefore the base can be prevented from blocking the seat frame side plate when the seat frame side plate moves downward. Moreover, the front projection of the connecting rod mechanism and the seat frame side plate on the plane of the vehicle body bottom plate and the front projection of the base on the plane of the vehicle body bottom plate are staggered, so that the blocking of the whole downward movement of the connecting rod mechanism and the seat frame side plate caused by the lower part of the base can be avoided when the whole of the connecting rod mechanism and the seat frame side plate is designed to move downward relative to the vehicle body bottom plate. The design of the low-sitting-position automobile seat framework platform can be realized by adjusting the relative positions of the base relative to the connecting rod mechanism and the seat frame side plates under the condition that the traditional seat structure is not greatly changed, the vertical height between the seat basin on the seat frame and the automobile body bottom plate is effectively reduced, the structure is simple and easy to implement, and the research and development cost is low.

In one possible implementation mode of the application, the orthographic projections of the link mechanism, the seat frame side plate and the base on the plane of the vehicle body bottom plate are staggered in pairs. Therefore, compared with the arrangement that one of the connecting rod mechanism and the seat frame side plate is staggered with the orthographic projection of the base on the plane of the vehicle body bottom plate, when the connecting rod mechanism and the seat frame side plate are integrally downwards moved relative to the vehicle body bottom plate, the blocking of the integral downwards movement of the connecting rod mechanism and the seat frame side plate caused by the fact that the base is arranged below the one of the connecting rod mechanism and the seat frame side plate is avoided, and on the other hand, the orthographic projection of the connecting rod mechanism and the seat frame side plate on the plane of the vehicle body bottom plate is staggered, so that the contact to the seat frame side plate during the movement of the connecting rod mechanism can be avoided.

In one possible implementation of the application, the lower surface of the base is abutted against the base, the upper surface of the base faces the bowl, and the lower end of the link mechanism is connected to the side of the base facing the link mechanism. Compared with the design of connecting the lower end of the link mechanism above the base in the related art, the design of connecting the lower end of the link mechanism to the side surface of the base facing the link mechanism obviously reduces the vertical height of the seat frame and the vehicle body bottom plate connected above the link mechanism.

In one possible implementation mode of the application, the base station is a sliding rail, the base comprises a sliding block and a bracket fixed on the sliding block, the lower surface of the sliding block is abutted against the sliding rail, the upper surface of the sliding block faces the seat basin, and the sliding block is positioned in the sliding rail and can slide in the sliding rail; the bracket is provided with a mounting structure which extends out of one side surface of the sliding block, which faces the connecting rod mechanism, and the lower end of the connecting rod mechanism is connected to the mounting structure. Here, the mounting structure of the bracket extends beyond the side of the slider facing the link mechanism, and it is emphasized that the mounting structure is located at a lateral position of the slider, so that the link mechanism is located at a lateral position of the slider on the base after the link mechanism is mounted on the mounting structure of the bracket.

According to the mounting structure, the first side plate on the support can extend out to the side of the sliding block, so that the connecting rod mechanism can be connected to the side of the sliding block, and the support can not block the downward movement of the connecting rod mechanism and the seat frame connected to the upper end of the connecting rod mechanism when the seat frame is designed to move downward relative to the vehicle body bottom plate.

In one possible implementation manner of the application, the bracket comprises a first bracket, the connecting part of the first bracket is a first flanging at one end of the second side plate far away from the supporting plate, the first flanging is positioned at one side of the second side plate far away from the first side plate, and the plane of the first flanging is parallel to the plane of the supporting plate; the first flanging is fixed on the upper surface of the sliding block and is attached to the upper surface of the sliding block, and the second side plate is fixed on the side wall of the sliding block and is attached to the side wall of the sliding block. Here, the mode that first turn-ups and the upper surface laminating of slider are fixed and second curb plate and slider lateral wall laminating are fixed can increase the fastness that support and slider are connected to and can promote the stability of whole seat skeleton platform.

In one possible implementation manner of the application, the bracket further comprises a second bracket, the connecting part of the second bracket is provided with a bending section, an extending section and a second flanging, the bending section is arranged at one end of the second side plate far away from the supporting plate, the plane of the bending section is parallel to the plane of the supporting plate, one side of the bending section far away from the second side plate is provided with the extending section which is inclined towards the supporting plate, the second flanging is arranged at the end part of the extending section, and the second flanging is parallel to the plane of the supporting plate and is positioned at one side of the first side plate far away from the second side plate; the second flanging is fixed on the upper surface of the sliding block and is attached to the upper surface of the sliding block, and the second side plate is partially fixed on the side wall of the sliding block and is attached to the side wall of the sliding block. By the design, the stability of the second bracket when being connected with the sliding block can be improved.

In one possible implementation manner of the application, the second side plate of the second bracket is provided with a second installation part, the first installation part and the second installation part are arranged in an aligned manner and are arranged at one ends of the first side plate and the second side plate far away from the supporting plate, wherein the lower end of the connecting rod mechanism is connected between the first side plate and the second side plate, the upper end of the connecting rod mechanism is connected on a seat frame side plate on the same side as the second bracket, and the orthographic projection of the seat frame side plate on the vehicle body bottom plate and the orthographic projection of the base platform on the vehicle body bottom plate are arranged in a staggered manner. Here, all set up the installation department on the first curb plate of second support and second curb plate, make link mechanism's lower extreme articulate between two curb plates, compare on only articulating one curb plate, can make the second support play powerful supporting role to link mechanism.

The embodiment of the application provides an automobile, which comprises a frame, wherein an automobile seat is arranged on an automobile body bottom plate of the frame. Wherein, one side of the automobile seat close to the automobile body bottom plate is connected with a base station, and the base station is fixedly connected with the automobile body bottom plate. Here, the base may be a slide rail, and the car seat is slidably connected to the underbody, so that the car seat can be moved relative to the underbody. Because of the high requirements of people on the comfort level of automobiles at present, the automobile seat sliding rail can be an ultra-long sliding rail on some vehicles such as business cars and high-end automobiles, so that the automobile seat has a larger sliding space, and the comfort level of passengers is improved. In addition, in addition to being able to slide back and forth relative to the underbody, the car seat is often required to have a height adjusting function relative to the underbody in order to further improve the comfort of the occupant.

Accordingly, embodiments of the present application provide an automotive seat that is coupled to an underbody that includes a seat frame platform, a seat pan, a back frame, and a drive member. The seat framework platform can be used for adjusting the height of the seat relative to the vehicle body bottom plate; the seat basin is arranged in a seat frame of the seat framework platform, the backrest framework is connected with the seat framework platform and is used for supporting and leaning an occupant, and the seat basin, the backrest framework and the seat framework platform form a seat framework of the automobile seat; the drive member is secured to the seat frame, such as the drive member may be secured to a seat frame or a seat pan of the seat frame for driving movement of a linkage mechanism in the seat frame platform to adjust the position of the seat pan relative to the underbody. Here, in order to meet the design requirements of some vehicle types, particularly pure electric vehicles, such vehicle types desire a lower Block value for the vehicle seat, and thus, there is an urgent need for a low-seated vehicle seat frame platform to achieve the design requirements.

To this end, the embodiment of the present application further provides a seat frame platform, and referring to fig. 1,2 and 3, the automobile seat frame platform includes a base 1, a seat frame 4 and a link mechanism 3. The base 1 is fixedly connected to a vehicle body bottom plate, the base 1 is connected with a base 2, and the base 2 can move relative to the base 1; the seat frame 4 is surrounded by two cross bars 41 and two seat frame side plates 42, and is arranged above the base 2 for mounting a seat basin (not shown in the figure); the upper end of the link mechanism 3 is connected with the seat frame side plate 42, and the lower end of the link mechanism 3 is connected with the base 2 for adjusting the relative position of the seat frame 4 and the base 1; at least one of the link mechanism 3 and the seat frame side plate 42 is arranged in a staggered manner in the orthographic projection of the plane of the vehicle bottom plate and the orthographic projection of the base 2 on the plane of the vehicle bottom plate.

Specifically, the base 1 is fixedly connected to the underbody, and a base 2 movable relative to the base 1 is connected to the base 1. Here, the specific implementation form in which the base 2 is movable relative to the base 1 is not limited, for example, the base 1 is a one-dimensional linear guide, the base 2 is a slider 21 slidably connected to the linear guide, the slider 21 is slidably connected to the linear guide, and for example, a roller is provided on a side of the base 2 near the base 1 to move the base 2 relative to the base 1, so that the seat frame platform connected to the base 2 can be moved relative to the floor of the vehicle body. Referring to fig. 1 and 2, in order to facilitate the display of the seat frame platform, the seat basin is not shown in the drawings, it can be seen that the seat frame 41 is formed by surrounding a cross bar 41 at the front end, a cross bar 41 at the rear end and two seat frame side plates 42 located at two sides, and a seat frame 4 with a rectangular frame structure is substantially surrounded, wherein preferably, the cross bar 41 is of a circular tube structure, two ends of the cross bar are welded and fixed with the seat frame side plates 42 respectively, and the seat frame side plates 42 are of a sheet metal structure formed by adopting stamping. The upper end of the link mechanism 3 is connected to the seat frame side plate 42, and the lower end of the link mechanism 3 is connected to the base 2, so as to adjust the relative position of the seat frame 4 and the base 1. Here, the connection form of the upper end of the link mechanism 3 and the seat frame side plate 42 and the connection form of the lower end of the link mechanism 3 and the base 2 are not limited, and preferably, a hinged connection form may be adopted, which is strong in stability and flexible in steering.

Here, the vertical height of the seat frame 4 and the floor can be reduced compared to the related art in such a manner that the orthographic projection of at least one of the link mechanism 3 and the seat frame side plate 42 on the floor surface is offset from the orthographic projection of the base 2 on the floor surface. Specifically, in the related art, since the base 2 is disposed under the link mechanism 3 or under the seat frame side plate 42, here, under may refer to directly under or an approximate directly under, that is, there is an overlap in projection of the base 2 and the link mechanism 3 on the floor, at which time the vertical height of the base 2, which is generally located on the base 1, with respect to the floor is unchanged, and in this case, when it is desired to move the link mechanism 3 downward toward the floor to lower the height of the seat frame 4 connected to the link mechanism 3 and the floor, it is difficult to achieve the lowering of the seat frame 4 because the base 2 has a blocking effect on the downward movement of the link mechanism 3 under the link mechanism 3.

In the implementation of the application, for example, when the orthographic projection of the link mechanism 3 on the plane of the vehicle body bottom plate and the orthographic projection of the base 2 on the plane of the vehicle body bottom plate are staggered, the link mechanism 3 is arranged at the side position of the base 2, so that when the link mechanism 3 is adjusted to move downwards relative to the vehicle body bottom plate, the base 2 is arranged at the side of the link mechanism 3, the avoidance effect can be achieved on the downward movement of the link mechanism 3 relative to the vehicle body bottom plate, namely, the height of the seat frame 4 connected with the link mechanism 3 relative to the vehicle body bottom plate can be reduced, and the design of the low sitting posture of the seat can be realized. In addition, similarly, for example, the orthographic projection of the seat frame side plate 42 on the plane of the vehicle bottom plate and the orthographic projection of the base 2 on the plane of the vehicle bottom plate may be staggered, so that the base 2 is prevented from blocking the seat frame side plate 42 when the seat frame side plate 42 moves downward, compared with the case that the base 2 is positioned below the seat frame side plate 42 in the related art, when the link mechanism 3 and the seat frame side plate 42 connected thereto move downward, because the base 2 is not positioned below the seat frame side plate 42. In addition, in the case where the link mechanism 3 and the seat frame side plate 42 are both disposed so as to be offset from the front projection of the chassis 2 on the plane of the chassis, the link mechanism 3 and the seat frame side plate 42 may be disposed so as not to block the downward movement of the link mechanism 3 and the seat frame side plate 42 due to the downward movement of the chassis 2.

The design above is that under the condition that the traditional seat structure is not changed greatly, the relative positions of the base 2 relative to the connecting rod mechanism 3 and the seat frame side plate 42 are adjusted, so that the design of the low-sitting-position automobile seat framework platform can be realized, the vertical height between the seat basin on the seat frame 4 and the automobile body bottom plate is effectively reduced, the structure is simple and feasible, and the research and development cost is low.

For example, referring to fig. 1,2 and 3, the link mechanism 3, the seat frame side plate 42 and the base 2 are disposed in a staggered manner in pairs in the orthographic projection on the plane of the underbody. Thus, compared with the arrangement that one of the link mechanism 3 and the seat frame side plate 42 is staggered with the orthographic projection of the base 2 on the plane of the vehicle body bottom plate, on one hand, when the link mechanism 3 and the seat frame side plate 42 are designed to move downwards relative to the vehicle body bottom plate, the whole of the link mechanism 3 and the seat frame side plate 42 cannot be blocked due to the fact that the base 2 is arranged below one of the link mechanism 3 and the seat frame side plate 42, and on the other hand, the orthographic projection of the link mechanism 3 and the seat frame side plate 42 on the plane of the vehicle body bottom plate is staggered, so that the link mechanism 3 can be prevented from touching the seat frame side plate 42 during movement. For example, in fig. 3, the link mechanism 3, the seat frame sideboard 42 and the base 2 are staggered in sequence, and the projection of the seat frame 4 on the plane where the vehicle body bottom plate is located covers the base 2, so that the design of the low-sitting seat framework platform can be conveniently realized, and the occupied space is small.

In some embodiments, referring to fig. 1,2 and 3, the lower surface of the base 2 abuts against the base 1, the upper surface of the base 2 faces the bowl, and the lower end of the link mechanism 3 is connected to the side of the base 2 facing the link mechanism 3. Compared with the design of connecting the lower end of the link mechanism 3 above the base 2 in the related art, the design of connecting the lower end of the link mechanism 3 to the side of the base 2 facing the link mechanism 3 obviously reduces the vertical height of the seat frame 4 and the vehicle body floor connected above the link mechanism 3, namely, the low seat posture design of the seat is realized.

The specific structural forms of the base 1 and the base 2 are not limited, and the base 2 may be movable relative to the base 1. For example, referring to fig. 1 and 2, the base 1 is a slide rail, the base 2 includes a slider 21 and a bracket 22 fixed on the slider 21, the lower surface of the slider 21 is in contact with the slide rail, the upper surface of the slider 21 faces the bowl, and a portion of the slider 21 is located in the slide rail and is capable of sliding in the slide rail. Preferably, the two sets of sliding rails are arranged side by side along the width direction of the vehicle body, and extend along the length direction of the vehicle body, wherein the length direction of the vehicle body is the running direction of the vehicle. The seat frame side plates 42 are correspondingly disposed above the two slide rails, the extending direction of the seat frame side plates 42 is parallel to the extending direction of the slide rails, the seat frame side plates 42 are erected above the vehicle body floor, and the two cross bars 41 are connected between the two seat frame side plates 42. The corresponding sliding blocks 21 are at least two groups, the lower surfaces of the sliding blocks 21 are in sliding abutting connection with the bottom surfaces of the sliding grooves of the sliding rails, at least part of the sliding blocks 21 face the seat basin and are exposed out of the sliding grooves of the sliding rails, at least part of the support 22 is fixedly connected with the sliding blocks 21, the support 22 is provided with a mounting structure 223 extending out of one side surface of the sliding blocks 21 facing the link mechanism 3, the lower end of the link mechanism 3 is connected to the mounting structure 223, and the support 22 is fixedly connected with the sliding blocks 21, so that the sliding blocks 21 can realize front-back adjustment of the automobile seat by means of the sliding rails, and meanwhile, the height adjustment of the seat frame 4 can be realized by the link mechanism 3 connected with the support 22.

Here, when the base 1 is a slide rail, it is preferable that the slider 21 has a columnar structure and the sectional shape of the slider 21 is square, so that the slider 21 having a square sectional shape facilitates the portion of the holder 22 to be fixedly attached to the side wall of the slider 21, compared to the circular and triangular sectional shapes of the slider 21.

In addition, the specific structural form of the mounting structure 223 on the bracket 22 is not limited. Referring to fig. 1,4 and 5, it is preferable that the mounting structure 223 on the bracket 22 is located at substantially the same height as the slider 21, wherein the mounting structure 223 of the bracket 22 protrudes from the side of the slider 21 facing the link mechanism 3, and emphasizes that the mounting structure 223 is located at a lateral position of the slider 21, so that the link mechanism 3 is located at a lateral position of the slider 21 on the base 2 after the link mechanism 3 is mounted on the mounting structure 223 on the bracket 22.

As an example, referring to fig. 2,4 and 5, the mounting structure 223 of the bracket 22 includes a horizontal support plate 2233, a first side plate 2231 and a second side plate 2232 vertically and fixedly connected to opposite sides of the support plate 2233, the first side plate 2231 is located in a plane parallel to a side surface of the slider 21 and facing the link mechanism 3, the first side plate 2231 has a first mounting part 2251 for connecting a lower end of the link mechanism 3 to the first side plate 2231, and the second side plate 2232 has a connecting part 224 for fixing the bracket 22 to the slider 21. The mounting structure 223 can enable the first side plate 2231 on the bracket 22 to extend to the side of the sliding block 21, so that the link mechanism 3 can be connected to the side of the sliding block 21, and further, when the link mechanism 3 and the seat frame 4 connected with the upper end of the link mechanism are designed to move downwards relative to the vehicle body bottom plate, the bracket 22 can not block the downward movement.

Further, in some embodiments, referring to fig. 2,4 and 5, the bracket 22 includes a first bracket 221, the connecting portion 224 of the first bracket 221 is a first flange 2241 on the end of the second side plate 2232 away from the support plate 2233, the first flange 2241 is located on one side of the second side plate 2232 away from the first side plate 2231, and the plane of the first flange 2241 is parallel to the plane of the support plate 2233; the first flange 2241 is fixed to the upper surface of the slider 21, and is bonded to the upper surface of the slider 21, and the second side plate 2232 is fixed to the side wall of the slider 21, and is bonded to the side wall of the slider 21. Here, the manner in which the first flange 2241 is attached to the upper surface of the slider 21 and the second side plate 2232 is attached to the side wall of the slider 21 may increase the connection firmness between the bracket 22 and the slider 21, and may improve the stability of the overall seat frame platform.

The connection manner in which the first flange 2241 is attached to the upper surface of the slider 21 and the second side plate 2232 is attached to the side wall of the slider 21 is not limited, and may be, for example, screw connection, welding, or the like, and preferably, a reliable connection manner may be employed.

In some embodiments, referring to fig. 1 and 2, the two first links 31 are each of a plate-like structure having substantially the same shape, and have mounting holes at both ends thereof for mounting the first links 31 between the seat frame side plate 42 and the base 2 via connectors; in addition, it should be noted that, here, the second connecting rod 32 and the third connecting rod 33 have different structural shapes, specifically, two opposite sides of one end of the second connecting rod 32 are provided with flanging structures, and the two flanging structures are located on the same side of the second connecting rod 32, one end of the second connecting rod 32 with the flanging structure is provided with a mounting hole, one end of one cross rod 41 passes through the mounting hole on the second connecting rod 32 and then is connected with the seat frame side plate 42, and the two flanging structures are attached to at least part of the cross rod 41 for improving the stability of the connection between the third connecting rod 32 and the seat frame 4; the third link 32 has a plate structure, and one end of the third link 32 has an arc toothed plate structure as shown in fig. 2, and the toothed plate structure of the third link 32 is used for meshing transmission with the output end of the driving member 5 arranged on the seat frame platform, so that the driving member 5 drives the third link 32 to rotate, and the whole link mechanism 3 is driven to synchronously link.

Here, the link mechanism 3 is preferably connected to the bracket 22 and the seat frame side plate 42 in a hinged manner. In addition, the first side plate 2231 of the first bracket 221 is hinged to the lower ends of the two first links 31 and the third links 33, and the first side plate 2231 of the second bracket 222 is hinged to the lower end of the second link 32. Specifically, referring to fig. 1, 2,4 and 5, for example, one of the first link 31 and the second link 32 is disposed at the same side, the side frame 2 is provided with a first bracket 221 and a second bracket 222 corresponding to the first link 31 and the second link 32, lower ends of the first link 31 and the second link 32 are respectively hinged to first mounting parts 2251 on first side plates 2231 of the first bracket 221 and the second bracket 222, and upper ends of the first link 31 and the second link 32 are respectively hinged to the same side frame side plate 42. Likewise, the other first link 31 and the third link 33 are hinged at both ends to the two first brackets 221 of the other-side base 2, respectively. Among them, the first mounting part 2251 on the first side plate 2231 may be a hinge hole and be hinged to the lower end of the link mechanism 3 by a shaft pin. In addition, the driving member 5 is connected to the seat frame side plate 42, so as to drive the link mechanism 3 to move, specifically, the output end of the driving member 5 is meshed with the toothed plate structure of the third link 32 to drive the link mechanism 3 to link, so as to realize the height adjustment of the seat frame 4 relative to the vehicle body bottom plate.

Continuing to refer to fig. 2,4 and 5, the second side plate 2232 of the second bracket 222 has a second mounting portion 2252, the first mounting portion 2251 and the second mounting portion 2252 are aligned and disposed at one ends of the first side plate 2231 and the second side plate 2232 away from the support plate 2233, wherein the lower end of the link mechanism 3 is connected between the first side plate 2231 and the second side plate 2232, and the upper end of the link mechanism 3 is connected to a seat frame side plate 42 on the same side as the second bracket 222, and the front projection of the seat frame side plate 42 on the vehicle body bottom plate is staggered from the front projection of the base 1 on the vehicle body bottom plate. Here, since the second link 32 is located at the rear position of the seat frame platform, when the occupant sits on the seat, the center of gravity of the occupant is close to the second link 32, and therefore the second link 32 needs to bear a larger pressure than the first link 31, so that the second bracket 222 hinged to the second link 32 also needs to have a stronger bearing capacity, and therefore, the mounting portions are provided on both the first side plate 2231 and the second side plate 2232 of the second bracket 222, so that the lower end of the second link 32 of the link mechanism 3 is hinged between the two side plates, and compared with the case where only one side plate is hinged to the second link 32, the second bracket 222 can exert a stronger supporting effect on the second link 32. In addition, since the second mounting portion 2252 is disposed on the second side plate 2232 of the second bracket 222, in the embodiment of the present application, the design of the bending section 2243 and the extending section 2244 in the connecting portion 224 of the second bracket 222 can form an avoidance space for the second mounting portion 2252 disposed on the second side plate 2232, so as to avoid that the second mounting portion 2252 on the second side plate 2232 protrudes from the second side plate 2232 and abuts against the slider 21, thereby affecting the smoothness of the front-rear sliding of the seat; on the other hand, the center of gravity of the second bracket 222 can be close to the sliding block 21, so that the stability of the seat support is improved.

The foregoing embodiment numbers of the present application are merely for the purpose of description, and do not represent the advantages or disadvantages of the embodiments. The foregoing description is only of the preferred embodiments of the present application, and is not intended to limit the scope of the application, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
