Description

Technical Field

[0001] This utility model relates to the technical field of automobile seats, and specifically to a rear-folding seat. Background Technology

[0002] As vehicles become more common, people have higher and higher requirements for cars. For example, they hope that the interior space can be as large as possible. In order to improve the utilization of the interior space, setting the rear seats of cars to be foldable or retractable is a common approach.

[0003] A Chinese utility model patent (application number 202421512002.4, utility model title: A Rear Seat Frame Capable of Sliding Forward and Backward and Folding Downward) discloses a rear seat frame capable of sliding forward and backward and folding downward. It includes a flipping component, a frame body, and floor locks. The flipping component is located at the rear ends of the left and right sides of the base frame, and the floor locks are located on the left and right sides of the front end of the base frame. Under the action of the flipping component, the folded rear seat flips backward to a horizontal position and rests on the bottom of the car's trunk, effectively expanding the usable space in the rear of the car. However, in this folding down rear seat frame, the flipping component causes the base frame to fold around the flipping center. After folding, the connection between the base frame and the flipping component protrudes from the car floor, occupying some usable space inside the car and affecting the utilization rate of the interior space. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a rear-folding seat to solve the problem that the existing rear seats that fold down and sink will partially protrude on the car floor after being flipped and folded, thus occupying usable space and affecting the utilization rate of the interior space.

[0005] The technical solution to achieve the above objectives is:

[0006] This utility model provides a rear-folding seat, mounted on a vehicle body and foldable into a recess formed on the vehicle body via a linkage mechanism. The rear-folding seat includes a base plate assembly lockable to the vehicle body and a seat cushion assembly mounted on the base plate assembly. The linkage mechanism is connected to both the vehicle body and the base plate assembly. When the base plate assembly is unlocked from the vehicle body, rotation of the linkage mechanism causes the base plate assembly to fold into the recess from the unlocked state. In the folded state, the upper surface of the rear-folding seat is not higher than the upper surface of the trim layer laid on the vehicle body. The linkage mechanism includes:

[0007] Linkage bracket;

[0008] A first link, the first end of which is rotatably connected to the base plate assembly, and the second end of which is rotatably connected to the link bracket;

[0009] The second link has a first end rotatably connected to the base plate assembly and a second end rotatably connected to the link bracket.

[0010] The rear-folding seat can be folded into the recess by rotating the first link and the second link.

[0011] A further improvement of this utility model of a reclining seat is that the connecting rod bracket is disposed on the wall of the recess, and the entire connecting rod bracket is located within the recess.

[0012] A further improvement of this utility model of a reclining seat is that the second link is located inside or outside the first link;

[0013] The rotatable connection between the second link and the link bracket is higher in the vertical direction than the rotatable connection between the first link and the link bracket;

[0014] And / or when the base plate assembly is locked to the vehicle body, the rotatable connection between the second link and the base plate assembly is higher in the vertical direction than the rotatable connection between the first link and the base plate assembly.

[0015] A further improvement of this utility model of a reclining seat is that it also includes a drive mechanism disposed on the linkage bracket. The drive mechanism is drivenly connected to the second end of the first linkage or the second linkage, and can drive the first linkage or the second linkage to rotate and adjust.

[0016] A further improvement of this utility model of a reclining seat is that the driving mechanism is a first motor, and the drive shaft of the first motor is drivenly connected to the second end of the first link or the second link.

[0017] A further improvement of this utility model of a reclining seat is that the drive mechanism includes an angle adjuster connected to the second end of the first link or the second link, and a second motor drivenly connected to the angle adjuster.

[0018] A further improvement of this utility model of a folding seat is that the base plate assembly is connected to the vehicle body through two linkage mechanisms, which are located on opposite sides of the base plate assembly.

[0019] A further improvement of this utility model of a reclining seat is that it also includes a first motor mounted on one of the two linkage mechanisms and a bidirectional leaf spring mounted on the other linkage mechanism.

[0020] The first motor is driven to the first or second link on the corresponding link bracket, and the bidirectional leaf spring is connected to the first or second link on the corresponding other link bracket to provide corresponding auxiliary spring force when the first or second link rotates.

[0021] A further improvement of this utility model of a reclining seat is that a cover is provided on the lower surface of the base plate assembly;

[0022] When the rear seat is folded down, the exposed surface of the cover is flush with the upper surface of the trim layer.

[0023] A further improvement of this utility model of a reclining seat is that a slide rail assembly is provided between the base plate assembly and the seat cushion assembly, and the seat cushion assembly can slide relative to the base plate assembly through the slide rail assembly.

[0024] This utility model also provides a rear-folding seat, which is installed on the car body and can be flipped and folded into a recess formed on the car body through a linkage mechanism. The rear-folding seat includes a seat cushion assembly and a backrest assembly installed on the seat cushion assembly. The linkage mechanism is connected to the car body and the seat cushion assembly respectively. When the seat cushion assembly is unlocked from the car body, the rotation of the linkage mechanism causes the seat cushion assembly to flip and fold into the recess from the unlocked state. In the folded state, the upper surface of the rear-folding seat is not higher than the upper surface of the trim layer laid on the car body.

[0025] The linkage mechanism includes:

[0026] Linkage bracket;

[0027] A first link, the first end of which is rotatably connected to the seat assembly, and the second end of which is rotatably connected to the link bracket;

[0028] The second link has a first end rotatably connected to the seat assembly and a second end rotatably connected to the link bracket.

[0029] The rear-folding seat can be folded into the recess by rotating the first link and the second link.

[0030] The beneficial effects of this utility model of a reclining seat are:

[0031] The rear-folding seat of this utility model forms a linkage mechanism with the first and second links, the linkage bracket, and the base plate assembly. The linkage mechanism enables the seat to flip and fold, allowing the seat to sink entirely into the recess when folded. The upper surface of the seat is not higher than the upper surface of the trim layer (such as carpet or floor mat) laid on the car body, avoiding the formation of a bulge on the car body surface after flipping and folding. This achieves a truly extra-large luggage space and effectively improves the utilization rate of the interior space.

[0032] The rear-folding seat of this utility model has no protruding structures on both sides. Compared with the structure in the prior art, the rear-folding seat of this utility model can save installation space on both sides. When the rear-folding seat of this utility model is equipped with a slide rail assembly, the slide rail assembly is set between the base plate assembly and the seat cushion assembly. The slide rail assembly does not need to be fixed to the car body. The rear-folding seat only needs to add an installation point between the rear of the base plate assembly and the car body, without occupying the space on both sides of the rear-folding seat.

[0033] The rear-folding seat of this utility model can be an integrated rear seat or a split rear seat composed of multiple rear-folding seats arranged side by side. The number of split seats can be set according to the size of the rear space of the car, such as two or three. Users can flexibly choose some of the seats to fold back to meet both cargo and passenger needs at the same time.

[0034] In the folded state, the backrest assembly of this utility model is generally parallel to the seat cushion assembly and the base plate assembly, or even if it is set at an angle, the angle is small. This makes the structure of the folded seat more compact and allows it to be folded and flipped within a limited recess size. Attached Figure Description

[0062] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0063] This utility model provides a rear-folding seat. A linkage mechanism formed by a first and second link drives the seat to fold flat rearward, allowing the entire seat to completely sink into the recess. There are no structural protrusions on the surface of the car body's trim layers, such as carpets or floor mats, achieving a better flattening effect and perfectly addressing users' needs for high comfort and large trunk space. The structure of this rear-folding seat is described below with reference to the accompanying drawings.

[0064] See Figure 1 This image shows a three-dimensional structural diagram of the rear-folding seat of this utility model from a first-view perspective. (See also...) Figure 2 This image shows a three-dimensional structural diagram of the rear-folding seat of this utility model from a second-view perspective. The following is in conjunction with... Figure 1 and Figure 2 The structure of the rear-folding seat of this utility model will be described.

[0065] like Figures 7 to 10As shown, the rear-folding seat 1 of this utility model is installed on the vehicle body, and the rear-folding seat 1 can be flipped and folded into a recess 22 formed on the vehicle body 21 via a linkage mechanism. The rear-folding seat 1 includes a base assembly 11 and a seat cushion assembly 12 disposed on the base assembly 11. The linkage mechanism is connected to the vehicle body 21 and the base assembly 11 respectively. When the base assembly 11 is in the unlocked state from the vehicle body 21, the rotation of the linkage mechanism causes the base assembly 11 to flip and fold into the recess 22 from the unlocked state. In the folded state, the upper surface of the rear-folding seat 1 is not higher than the upper surface of the trim layer 23 laid on the vehicle body 21. The trim layer 23 can be a carpet layer laid on the vehicle body 21, or a floor mat layer laid on the vehicle body 21, etc.

[0066] The flip-up adjustment of the rear-folding seat 1 of this utility model is driven by the rotation of the linkage mechanism, that is, the rotation of the linkage mechanism causes the rear-folding seat 1 to flip and fold into the recess 22. The rear-folding seat 1 of this utility model can be configured as a split rear seat, which is composed of two or more of the rear-folding seats 1, or the rear-folding seat 1 can be configured as an integrated rear seat.

[0067] Further, the linkage mechanism includes a linkage bracket 101, a first linkage 102, and a second linkage 103; the first linkage 102 includes a first end and a second end disposed opposite to each other, the first end of the first linkage 102 is rotatably connected to the base plate assembly 11, and the second end of the first linkage 102 is rotatably connected to the linkage bracket 101; the first end of the second linkage 103 is rotatably connected to the base plate assembly 11, and the second end of the second linkage 103 is rotatably connected to the linkage bracket 101; wherein, the rear-folding seat 1 can be folded into the recess 22 by rotating the first linkage 102 and the second linkage 103, and in the folded state, the upper surface of the rear-folding seat 1 (that is, the surface facing upward in the folded state or the lower surface of the base plate assembly 11) is not higher than the upper surface of the trim layer 23 laid on the car body 21.

[0068] Furthermore, such as Figures 11 to 13 The diagram shows the flipping process of the rear-hinged seat 1 from the locked state to the folded state. Combined with... Figure 8 and Figure 10As shown, when the folding seat 1 is flipped and folded, the front part of the folding seat 1 rotates together with the first link 102 and the second link 103, and then rotates and folds into the recess 22 formed on the car body 21. The folding adjustment of the folding seat 1 of this utility model can be achieved manually or electrically. The rotation center of the folding seat 1 is the center of the rotatable connection of the second end of the first link 102, wherein the first link 102 is the driving rotating component and the second link 103 is the driven rotating component, and the second link 103 rotates with the rotation of the first link 102. When the reclining seat 1 is folded down, the first link 102 rotates around point A, and the second link 103 rotates around point B. Point A is the rotatable connection point between the first link 102 and the link bracket 101, and point B is the rotatable connection point between the second link 103 and the link bracket 101. The link bracket 101 is located in the recess 22, so that both points A and B are located within the recess 22. When the reclining seat 1 is in the folded state, the lower surface of the base plate assembly 11 faces upward, and the lower surface of the base plate assembly 11 is not higher than... The upper surface of the trim layer 23 laid on the car body 21, that is, the lower surface of the base plate assembly 11 in the folded state, is flush with or lower than the upper surface of the trim layer 23 laid on the car body 21. The trim layer 23 can be a carpet layer laid on the car body 21, or a floor mat layer laid on the car body 21, etc., so that the folding effect of the rear seat 1 is flatter, which can meet more functional needs and realize a truly large luggage space.

[0069] Furthermore, such as Figure 3 As shown, the first end of the first link 102 is rotatably connected to the base plate assembly 11 at a position near the rear or middle, and the first end of the second link 103 is rotatably connected to the base plate assembly 11 at a position near the rear or middle.

[0070] In one specific embodiment of this utility model, the second connecting rod 103 is located inside or outside the first connecting rod 102; combined with Figure 8 and Figure 10As shown, when the reclining seat 1 is in the locked state, the rotatable connection between the second link 103 and the base plate assembly 11 is higher in the vertical direction than the rotatable connection between the first link 102 and the base plate assembly 11; when the reclining seat 1 is in the folded state, the rotatable connection between the second link 103 and the base plate assembly 11 is flipped to a lower position, that is, the rotatable connection between the second link 103 and the base plate assembly 11 is lower than the rotatable connection between the first link 102 and the base plate assembly 11, and the rotatable connection between the second link 103 and the base plate assembly 11 can sink into the recess 22, and / or, the rotatable connection between the second link 103 and the link bracket 101 is higher in the vertical direction than the rotatable connection between the first link 102 and the link bracket 101.

[0071] Combination Figure 19 and Figure 20 As shown, during the process of the floor assembly 11 flipping and folding into the recess 22 along the F direction, the rear end of the floor assembly 11 moves along the trajectory of curve E. When the rear end of the floor assembly 11 passes point E1 on curve E near the opening of the recess 22, the rear end of the floor assembly 11 will move towards the front of the vehicle until the rear seat 1 is completely flipped into the recess 22. The rear end of the floor assembly 11 is located at point E2. The horizontal distance between point E1 and point E2 on curve E is X1. That is, the rear end of the floor assembly 11 moves a distance X1 towards the front of the vehicle in the horizontal direction during the process of entering the recess 22. This distance X1 compensates for the seat posture, making the X-direction (the front-to-back direction of the vehicle is the X-direction) distance required for the rear seat 1 to flip and fold during the process shorter, reducing the position occupied by the recess 22 on the vehicle body in the X direction. Furthermore, the floor assembly 11 moves forward after passing point E1 because the first link 102 and the second link 103 are designed such that when the rear-folding seat 1 is locked, the rotational connection between the second link 103 and the link bracket 101 is higher in the vertical direction than the rotational connection between the first link 102 and the link bracket 101, and the rotational connection between the second link 103 and the floor assembly 11 is also higher in the vertical direction than the rotational connection between the first link 102 and the floor assembly 11. However, when the second link 103 rotates to a horizontal position, the horizontal distance between its two ends is at its maximum. When the second link 103 continues to rotate downwards in the horizontal position, the distance between its two ends decreases again. This is equivalent to moving the floor assembly 11 forward in the X direction, shortening the distance in the X direction, thus allowing it to be accommodated in a shorter recess 22 in the X direction to meet the needs of more vehicle models. Furthermore, combined with Figure 3 and Figure 4As shown, a support 112 is provided on the base plate assembly 11, and the support 112 is rotatably connected to the corresponding end of the second connecting rod 103. Preferably, the end of the second connecting rod 103 is rotatably connected to the support 112 via a second hinge 1031, which can be a pin or bolt or other hinged component. Specifically, the support 112 includes a first transverse portion connected to the base plate assembly 11 and a first vertical portion perpendicularly connected to the first transverse portion. The upper part of the first vertical portion is rotatably connected to the corresponding end of the second connecting rod 103. By providing the support 112, the rotatable connection point between the second connecting rod 103 and the base plate assembly 11 is higher in the vertical direction than the rotatable connection point between the first connecting rod 102 and the base plate assembly 11.

[0072] Furthermore, such as Figure 3 and Figure 4 As shown, the first end of the first link 102 is rotatably connected to the side of the base plate assembly 11. When the rear seat is locked, the rotatable connection of the first end of the first link 102 is higher than the lower surface of the base plate assembly 11 in the vertical direction. Thus, when the rear seat is folded down, the lower surface of the base plate assembly 11 faces upward, and the rotatable connection of the first end of the first link 102 is located below the lower surface, without being exposed or protruding.

[0073] Furthermore, a mounting base 113 is provided on the base plate assembly 11 corresponding to the first end of the first connecting rod 102. This mounting base 113 is used to rotatably connect to the first end of the first connecting rod 102, providing a mounting foundation for the first connecting rod 102. When the rear-folding seat 1 is in the locked state, the top of the mounting base 113 is lower than the top of the support 112 in the vertical direction. Specifically, the mounting base 113 includes a second transverse portion connected to the base plate assembly 11 and a second vertical portion perpendicularly connected to the second transverse portion. The upper part of the second vertical portion is rotatably connected to the first end of the first connecting rod 102. The first end of the first connecting rod 102 is rotatably connected to the mounting base 113 via a first hinge 1021, which can be a pin or bolt or other hinged component.

[0074] In a preferred embodiment, the base plate assembly 11 of this utility model can be a welded base plate frame structure or a plate-like structure, and may also include the plate-like structure and multiple supporting frames connected to the plate-like structure. Correspondingly, the support 112 and the mounting base 113 can be connected to the base plate frame structure or to the plate-like structure.

[0075] In one specific embodiment of this utility model, such as Figure 3 and Figure 4As shown, the rotatable connection between the second link 103 and the link bracket 101 is higher in the vertical direction than the rotatable connection between the first link 102 and the link bracket 101.

[0076] Specifically, the other end of the second link 103 can be rotatably connected to the link bracket 101 via another second hinge 1031, which can be a pin or bolt or other part that can achieve hinge.

[0077] Furthermore, the linkage bracket 101 includes an inner side plate and an outer side plate disposed opposite to each other, wherein the second end of the first link 102 is rotatably connected to the middle of the outer side plate, and one end of the second link 103 is rotatably connected to the upper part of the inner side plate.

[0078] Furthermore, the first link 102 is located on the outer side of the base plate assembly 11, while the second link 103 is located on the inner side of the base plate assembly 11. This saves lateral space in the base plate assembly 11, namely the installation space at the wheel hub of the vehicle side panel. Of course, the second link 103 of the rear-folding seat of this utility model can also be located on the outer side of the first link 102 or on the outer side of the base plate assembly 11.

[0079] In one specific embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the rear-folding seat 1 of this utility model also includes a drive mechanism 104 mounted on the linkage bracket 101. The drive mechanism 104 is driven to the second end of the first linkage 102 or the second linkage 103, and can drive the first linkage 102 or the second linkage 103 to rotate and adjust.

[0080] The first link 102 or the second link 103 is driven by the drive mechanism 104 to rotate and adjust. The first link 102 or the second link 103 then drives the base plate assembly 11 to rotate and adjust, thereby realizing the automatic drive of the rear-folding seat 1 to the folded state or the use state / locked state.

[0081] In a preferred embodiment, combined with Figure 4As shown, the drive mechanism 104 is a first motor 1041, which is driven to the second end of the first connecting rod 102 or the second connecting rod 103. The first motor 1041 can drive the first connecting rod 102 or the second connecting rod 103 to rotate and adjust. The motor shaft or drive shaft of the first motor 1041 can be directly driven to the second end of the first connecting rod 102 or the second connecting rod 103, or the motor shaft or drive shaft of the first motor 1041 can be driven to the second end of the first connecting rod 102 or the second connecting rod 103 through a gearbox. The drive mechanism 104, consisting of the first motor 1041 and the gearbox, is fixed to the connecting rod bracket 101 by a first fastener 1043. Preferably, the first fastener 1043 is a self-tapping screw or a connecting bolt. The drive mechanism 104 can be fixedly connected to the outer side plate of the connecting rod bracket 101 by the first fastener 1043. A connecting hole is provided at the second end of the first connecting rod 102 on the outer side plate. The second fastener 1022 passes through the second end of the first connecting rod 102 and is connected to the drive shaft 1023. The drive shaft 1023 passes through the connecting hole on the outer side plate via a bushing 1024. Specifically, the bushing 1024 is nested in the connecting hole of the outer side plate. The drive shaft 1023 passes through the bushing 1024 and is then securely connected to the gearbox. The motor shaft of the first motor 1041 can drive the gearbox to rotate. The gearbox rotates together with the second fastener 1022 and the first connecting rod 102 through the drive shaft 1023. The second fastener 1022 is preferably a connecting bolt or connecting pin. The first motor 1041 preferably has a locking function, so the linkage mechanism can be locked through the locking function of the first motor 1041, ensuring a reliable structure and preventing vertical wobbling.

[0082] In another preferred embodiment, the drive mechanism 104 includes an angle adjuster connected to the second end of the first link 102 or the second link 103, and a second motor driven by the angle adjuster. The fixed plate of the angle adjuster is connected to the link bracket 101, and the rotating plate of the angle adjuster is connected to the second end of the first link 102 or the second link 103, as shown below. Figure 14 As shown, the second motor 1049 drives the angle adjuster to rotate, thereby driving either the first link 102 or the second link 103 to rotate. Specifically, Figure 14A rear seat 3 for a car is shown. This rear seat 3 is a 40 / 60 split seat, including two sizes of folding seats. The drive mechanism for both sizes of folding seats includes a first adjuster 1046, a second adjuster 1047, a synchronizing rod 1048, and a second motor 1049. A linkage mechanism is provided on each side of the folding seat. The first adjuster 1046 and the second adjuster 1047 are located at corresponding linkage brackets 101. The rotating disks of the first adjuster 1046 and the second adjuster 1047 are connected to the second end of the corresponding first linkage 102 or second linkage 103. The fixed plates of the first angle adjuster 1046 and the second angle adjuster 1047 are connected to the corresponding connecting rod brackets 101. The first angle adjuster 1046 and the second angle adjuster 1047 can be located on the inner side or the outer side of the connecting rod brackets 101. The first angle adjuster 1046 and the second angle adjuster 1047 are connected by a synchronizing rod 1048 to achieve synchronous rotation. The second motor 1049 is located on the corresponding connecting rod bracket 101 and is driven by the first angle adjuster 1046 to drive the rotating plate of the first angle adjuster 1046 to rotate, thereby synchronously driving the two first connecting rods 102 or the two second connecting rods 103 to rotate. Preferably, the second motor 1049 has a locking function, so the linkage mechanism can be locked by the locking function of the second motor 1049, ensuring a reliable structure and preventing vertical swaying.

[0083] In one specific embodiment of this utility model, such as Figures 2 to 4 As shown, the base plate assembly 11 is connected to the vehicle body 21 via two linkage mechanisms, which are located on opposite sides of the base plate assembly 11. Thus, there are two first linkages 102 and two second linkages 103; the two first linkages 102 are located on opposite sides of the base plate assembly 11; a tie rod 106 connects the two second linkages 103; and two linkage brackets 101 are also provided. By providing two first linkages 102, two second linkages 103, and two linkage brackets 101, the rear-folding seat 1 of this invention can have high stability during the flipping process.

[0084] Furthermore, the tie rod 106 is a horizontal tube that supports and connects the two second connecting rods 103 by means of connecting bolts or welding. The tie rod 106 can improve the structural strength of the connection between the two second connecting rods 103, and the tie rod 106 can also allow the two second connecting rods 103 to rotate synchronously.

[0085] Furthermore, the reclining seat 1 also includes a drive mechanism 104 mounted on a linkage bracket 101. This drive mechanism 104 is driven to the second end of the first linkage 102 or the second linkage 103, and can drive the first linkage 102 or the second linkage 103 to rotate for adjustment. In this embodiment, the drive mechanism 104 includes a first motor 1041 mounted on one linkage bracket 101 and a bidirectional leaf spring 1042 mounted on another linkage bracket 101. The first motor 1041 can drive the corresponding first linkage 102 or the second linkage 103 to rotate for adjustment, and the bidirectional leaf spring 1042 can provide corresponding auxiliary spring force when the first linkage 102 or the second linkage 103 on the other linkage bracket 101 rotates.

[0086] Preferably, the two-way leaf spring 1042 can provide auxiliary elastic force in two directions of rotation. By setting the two-way leaf spring 1042, the tilting adjustment of the rear seat 1 can be made more effortless.

[0087] The specific connection relationship of the double-sided leaf spring 1042 is explained below using the driving connection between the double-sided leaf spring 1042 and the first connecting rod 102 on the connecting rod bracket 101 as an example. Specifically, as follows... Figure 4 As shown, a rotatable sleeve 1044 is provided between the inner and outer plates of the connecting rod bracket 101. The middle part of the bidirectional leaf spring 1042 is sleeved and fixed on the sleeve 1044, and the bidirectional leaf spring 1042 is located between the inner and outer plates. An upper limit member 1011 and a lower limit member 1012 are also provided between the inner and outer plates of the connecting rod bracket 101. The bidirectional leaf spring 1042 is provided with leaf springs that provide two directions of rotation. The outer end of one leaf spring is connected to the upper limit member 1011, and the outer end of the other leaf spring is connected to the lower limit member 1012. The second end of the first connecting rod 102 on the outer side of the connecting rod bracket 101 is fastened to the sleeve 1044 through a connector 1045. The connector 1045 is preferably threaded to the sleeve 1044, but it is not limited to threaded connection; welding can also be used. When the first link 102 on this side rotates toward the folded state, one of the leaf springs (i.e., the first leaf spring) can provide auxiliary elastic force in this direction of rotation, while the other leaf spring (i.e., the second leaf spring) rotates to store energy. Conversely, when the first link 102 rotates toward the use state / locked state, the second leaf spring can provide auxiliary elastic force, and the first leaf spring can rotate to store energy.

[0088] In another preferred embodiment, a two-way leaf spring 1042 is provided at both connecting rod brackets 101. In this embodiment, the flipping adjustment of the rear seat 1 is done manually. The two-way leaf spring 1042 provides auxiliary elastic force for the flipping adjustment, making the flipping process more effortless.

[0089] In one specific embodiment of this utility model, such as Figures 7 to 10 As shown, the linkage bracket 101 is disposed on the recess wall 221 of the recess 22, and the linkage bracket 101 is entirely located within the recess 22. The recess 22 is formed in the trunk area of ​​the vehicle body 21, and the recess 22 is used to accommodate the folded-down rear seat 1.

[0090] In one embodiment, the connecting rod bracket 101 is fixedly connected to the pit wall 221 of the recess 22, in combination with... Figure 4 As shown, a connecting plate is connected between the inner and outer plates of the connecting rod bracket 101. The connecting plate can be attached to the pit wall 221 of the recess 22 and then fixed to the pit wall 221 by bolts.

[0091] In another implementation, combined Figure 7 and Figure 8 As shown, a portion of the connecting rod bracket 101 is close to the pit wall 221. A fixing plate 1013 is provided on the upper part of the connecting rod bracket 101, and this fixing plate 1013 is fixedly connected to the vehicle body 21 at the pit opening 22. Specifically, a connecting plate connects the inner and outer side plates of the connecting rod bracket 101. The top of this connecting plate is bent to form the fixing plate 1013, which is attached to the vehicle body 21 and fixedly connected to the vehicle body 21 by bolts.

[0092] In one specific embodiment of this utility model, such as Figure 9 As shown, a cover 111 is provided on the lower surface of the base assembly 11; when the rear-folding seat 1 is in the folded state, combined with Figure 10 As shown, the exposed surface of the cover 111 is flush with the upper surface of the finish layer 23. The cover 111 can be made of the same material as the finish layer 23, or it can be made of plastic. The cover 111 serves a decorative function.

[0093] In one specific embodiment of this utility model, such as Figures 1 to 3 As shown, the front of the base plate assembly 11 is connected to the vehicle body 21 via a locking mechanism 105. This locking mechanism 105 is fixed to the vehicle body 21 and can lock the front of the base plate assembly 11, as well as release the base plate assembly 11, allowing the base plate assembly 11 to be flipped and folded.

[0094] The locking mechanism 105 can be a hook, a floor lock, or other similar structure.

[0095] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, a slide rail assembly 14 is provided between the base plate assembly 11 and the seat cushion assembly 12. The slide rail assembly 14 provides the seat cushion assembly 12 with front and rear adjustment function, which can meet the comfort requirements of passengers of different body types.

[0096] Furthermore, combined Figure 6 As shown, the reclining seat 1 also includes a backrest assembly 13, which is rotatably connected to the rear of the seat cushion assembly 12, in conjunction with... Figure 7 and Figure 9 As shown, when flipping and folding the rear-folding seat 1, the backrest assembly 13 is first flipped over to be above the seat cushion assembly 12, and then the first linkage 102 is rotated to fold the rear-folding seat 1. Alternatively, the backrest assembly 13 is connected to the slide rail assembly 14, and the backrest assembly 13 can be rotated and adjusted relative to the slide rail assembly 14.

[0097] In one specific embodiment of this utility model, a folding seat 1 is also provided, which is mounted on a vehicle body 21 and can be folded and rotated into a recess 22 formed on the vehicle body 21 via a linkage mechanism. The folding seat 1 includes a seat cushion assembly 12 and a backrest assembly 13 mounted on the seat cushion assembly 12. The linkage mechanism is connected to both the vehicle body 21 and the seat cushion assembly 12. When the seat cushion assembly 12 is unlocked from the vehicle body 21, rotation of the linkage mechanism causes the seat cushion assembly 12 to fold and rotate into the recess 22. In the folded state, the upper surface of the folding seat 1 is not higher than the upper surface of the trim layer 23 laid on the vehicle body 21. The specific structure of this linkage mechanism can be the same as the linkage mechanism described above in this utility model.

[0098] In one specific embodiment of this utility model, such as Figures 15 to 18 As shown, another type of rear seat 3 for automobiles is illustrated. This rear seat 3 is a 40 / 60 split seat, including two sizes of folding seats. Both sizes of folding seats have a flip-up and folding function. In actual use, either folding seat can be folded down as needed, leaving the other folding seat open to simultaneously meet both cargo and passenger needs. When both folding seats need to be folded into the pit, different torques can be output by adjusting the duty cycle to ensure that the two folding seats fold down at the same speed, achieving simultaneous folding and entry into the pit. In this embodiment, the rear seat 3 is a 40 / 60 split seat. Of course, the structure of the rear seat 3 is not limited to this; it can also be a 50 / 50 split seat, or it can be formed by combining three or more folding seats.

[0099] like Figure 18 As shown, the two first connecting rods 102 of the rear-folding seat 1 of this utility model are set close to the two sides of the base plate assembly 11, so that the rear-folding seat 1 has no structural protrusions on the sides, saving space on the sides of the rear-folding seat 1 and improving the utilization rate of the vehicle interior space to a greater extent.

[0100] Combination Figure 3 and Figure 8As shown, the second end of the connecting rod bracket 101 of this utility model is located in the recess. When the drive mechanism 104 is installed, the drive mechanism 104 is installed on the second end of the connecting rod bracket 101 on the same axis and is also located in the recess. It does not encroach on the space above the car body 21. The rear-folding seat 1 only needs to add a mounting point between the rear of the base plate assembly 11 and the car body 21, saving the installation space at the wheel hub of the vehicle side panel.

[0101] In one specific embodiment of this utility model, such as Figure 7 , Figure 8 and Figure 11 As shown, the base plate assembly 11 of the rear-folding seat 1 of this invention is set at a certain angle (i.e., the first angle) with the car body 21. The angle value of the first angle is smaller than the angle value of the second angle between the base frame and the car body in the prior art, so that the rear-folding seat 1 of this invention can have better comfort when adjusting forward and backward. In the prior art, the second angle is set at a larger angle so that the seat can sink into the recess as much as possible after folding, because its rotation center is set at the connection of the flipping component at the rear end of the base frame.

[0102] Furthermore, combined Figure 9 and Figure 10 , Figure 12 and Figure 13 As shown, the backrest assembly 13 can be flipped and folded to be roughly parallel to the seat cushion assembly 12, or flipped and folded to be tilted at a certain angle to the seat cushion assembly 12. The angle should be as small as possible so that the rear seat 1 can form a more compact structure when folded, which allows the recess 22 to be designed to be smaller, thus meeting the requirements of the limited luggage space.

[0103] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
