Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a variable rear middle seat and a cockpit layout structure. Background Art

[0002] With the development of electric and intelligent automobiles, people are no longer satisfied with cars as a means of transportation. Instead, they are more concerned about the overall riding comfort. Therefore, versatile seats came into being.

[0003] Variable seats specifically refer to the adjustable rear seats of the car. In traditional five-seater cars, the rear seats are fixed, and only the front driver and co-driver seats can be adjusted forward and backward. With the continuous development of technology in the automotive field, nowadays, most of the rear seats of cars have developed into variable seats, which ensure the comfort of the rear passengers by adjusting the front and rear position of the rear seats.

[0004] Nowadays, most of the five-seater cars on the market have only changed the seating space through the changeable seats, but have not changed the number of seats. Since the rear seats are mostly one-piece structures, a few manufacturers have developed foldable rear seats, which makes the car change from five seats to two seats. However, the market lacks a design that transforms a traditional five-seater car into a business four-seater car. Utility Model Content

[0005] In view of this, one of the purposes of the present invention is to provide a variable rear middle seat, aiming to enable the traditional five-seater car to be transformed into a four-seater car.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A variable rear middle seat comprises a seat frame and a seat basin located above the seat frame frame, a first connecting rod and a second connecting rod are provided between the seat frame frame and the seat basin, and is characterized in that: the two ends of the first connecting rod and the second connecting rod are respectively hinged on the seat frame frame and the seat basin, so that the seat frame frame, the first connecting rod, the seat basin and the second connecting rod form a four-bar mechanism; a driving assembly is provided on the seat frame frame, and the driving assembly is used to drive the first connecting rod and the second connecting rod to rotate with the seat frame frame as a fulcrum, so that the seat basin can move forward relative to the seat frame frame.

[0008] With the above structure, the four-link mechanism can be driven by the driving assembly to move the seat pan forward and dock with the central armrest box, thereby converting the rear row of the car from three seats to two seats.

[0009] Preferably, two groups of first connecting rods and second connecting rods are connected between the seat frame and the seat basin, and the two groups of first connecting rods and second connecting rods are symmetrically arranged on the left and right sides of the seat basin. The above structure can make the connection structure between the seat frame and the seat basin more stable.

[0010] Preferably, the front end of the seat frame is provided with a vertically upward limit block, the rear end of the seat frame is provided with a limit pin, the second connecting rod is provided with a second bayonet corresponding to the limit pin, and when the seat basin is folded, the limit block can abut against the second bayonet, and the front end of the seat basin can abut against the limit block. With the above structure, the seat basin can be folded in a suitable position and form a stable support.

[0011] Preferably, the driving assembly can actively drive the lower end of the first connecting rod to rotate, the driving assembly is a driving motor, the output shaft of which is provided with an output gear, the lower part of the first connecting rod is provided with an arc-shaped toothed plate, and the output gear meshes with the arc-shaped toothed plate. The above structure can provide a power source for the seat basin to move forward.

[0012] Preferably, a first bayonet is provided on the first connecting rod, and the output gear can abut against the first bayonet when the seat pan is folded. The above structure can protect the output gear.

[0013] Preferably, a mounting bracket is provided on the seat frame, the drive motor is fixedly mounted on the mounting bracket, the first connecting rod is provided with an arc hole, and the mounting bracket is inserted into the arc hole. With the above structure, the arc hole can limit the rotation angle of the first connecting rod to avoid over-travel, and can also guide the rotation of the first connecting rod.

[0014] As a preference: the first connecting rod and the second connecting rod are arranged in parallel and have the same length, the two ends of the first connecting rod are respectively hinged at the front end of the seat frame frame and the middle position of the seat pot, and the two ends of the second connecting rod are respectively hinged at the middle position of the seat frame frame and the rear end of the seat pot. With the above structure, the four-bar linkage is a parallelogram structure, thereby ensuring that the seat pot moves forward in a nearly translational posture, and the hinged position of the first connecting rod and the second connecting rod makes the seat pot more stable, and the first connecting rod is arranged at the front end of the seat frame frame, and through the front end drive, the seat pot can be more effectively stressed when moving.

[0015] Preferably, the driving assembly includes a motor and an angle adjuster. The above structure can provide power for the movement of the seat basin.

[0016] Preferably, a synchronization rod is arranged between the two first connecting rods. With the above structure, only one set of driving components is needed to synchronously drive the two four-link assemblies to rotate synchronously.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. By adopting the variable rear middle seat and cockpit layout structure provided by the utility model, the four-link mechanism is driven by the driving assembly, so that the seat basin can be moved forward and docked with the central armrest box, thereby satisfying the requirement of switching the car seat between five seats and four seats at will.

[0021] 2. The first connecting rod and the second connecting rod are arranged in parallel and have the same length, so that the seat basin can move forward in a nearly translational manner. The entire process occupies less longitudinal space and is very stable during movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model is further described below in conjunction with embodiments and drawings.

[0029] Embodiment 1:

[0030] like Figure 1 and Figure 2As shown, a variable rear middle seat includes a seat pot 1 and a seat pot 2 installed above the seat frame frame 1, and the seat frame frame 1 and the seat pot 2 are connected by a first connecting rod 3 and a second connecting rod 4. In this embodiment, both ends of the first connecting rod 3 and the second connecting rod 4 are respectively hinged to the seat frame frame 1 and the seat pot 2 in an articulated manner, so that a four-bar linkage is formed between the seat frame frame 1, the first connecting rod 3, the seat pot 2 and the second connecting rod 4, and a driving assembly 5 is also fixedly mounted on the seat frame frame 1, and the driving assembly 5 can drive the first connecting rod 3 and the second connecting rod 4 to rotate with the seat frame frame 1 as a fulcrum, so that the seat pot 2 can move forward relative to the seat frame frame 1 and finally dock with the central armrest box.

[0031] With such a design, the four-link rod is driven to rotate by the driving assembly 5, so that the seat pan 2 can be moved forward, thereby realizing the conversion of the rear seats of the vehicle from three seats to two seats.

[0032] In this embodiment, two sets of first connecting rods 3 and second connecting rods 4 are hinged between the seat frame frame 1 and the seat basin 2, and the two sets of first connecting rods 3 and second connecting rods 4 are symmetrically arranged on the left and right sides of the seat basin 2, so that the connection between the seat frame frame 1 and the seat basin 2 is more stable, thereby ensuring that the seat basin 2 will not shake when moving forward.

[0033] In addition, a synchronization rod 6 is connected between the two first connecting rods 3, and the synchronization rod 6 can ensure that only one set of driving components 5 is required to achieve synchronous control of the two sets of four-link components.

[0034] In this embodiment, the first connecting rod 3 and the second connecting rod 4 are arranged in parallel and have the same length. Since the first connecting rod 3 and the second connecting rod 4 are arranged in parallel and have the same length, the entire four-bar linkage is a parallelogram, so that the seat basin 2 moves forward in an approximately translational posture. During the entire movement process, the longitudinal space occupies a small area, and at the same time, it can ensure that during the movement of the seat basin 2, objects placed at the bottom of the seat basin 2 will not fall off.

[0035] Furthermore, the two ends of the first connecting rod 3 are respectively hinged at the front end of the seat frame frame 1 and the middle position of the seat basin 2, and the two ends of the second connecting rod 4 are respectively hinged at the middle position of the seat frame frame 1 and the rear end of the seat basin 2. In this way, the driving component 5 drives the first connecting rod 3 to directly apply force to the middle of the seat basin 2, so that the seat basin 2 is subjected to more uniform force.

[0036] like Figure 5As shown, a vertically upward limit block 1a is formed at the front end of the seat frame frame 1, a limit pin 1b is fixedly inserted at the rear end of the seat frame frame 1, and a second clip 4a is formed on the second connecting rod 4 corresponding to the limit pin 1b. When the seat basin 2 is in a folded state, the limit block 1a can abut against the second clip 4a, and the front end of the seat basin 2 can abut against the limit block 1a, so as to ensure that the seat basin 2 can be limited in a suitable position when folded, thereby forming a stable support.

[0037] like Figure 4 and Figure 5 As shown, the driving assembly 5 can actively drive the lower end of the first connecting rod 3 to rotate. In this embodiment, the driving assembly 5 is a driving motor. Three mounting brackets 1c are fixedly installed on the inner side of the seat frame frame 1, and the driving motor is fixedly installed on the three mounting brackets 1c by bolts. An output gear 5a is fixedly installed at the output end of the driving motor, and an arc-shaped toothed plate 3a is installed at one end of the first connecting rod 3 close to the output gear 5a, and the output gear 5a and the arc-shaped toothed plate 3a are meshed with each other. Through the meshing transmission of the gear 5a and the arc-shaped toothed plate 3a, the first connecting rod 3 can be rotated relative to the seat frame frame 1.

[0038] An arc-shaped hole 3c is also provided at one end of the first connecting rod 3 close to the driving assembly 5, and the arc-shaped hole 3b and the arc-shaped tooth plate 3a are located in the same sector-shaped area, and one of the mounting supports 1c is penetrated inside the arc-shaped hole 3b. With such a design, the first connecting rod 3 can be limited in rotation through the interaction between the arc-shaped hole 3b and the mounting support 1c.

[0039] In this embodiment, the arc-shaped tooth plate 3 a is fixedly installed by bolts. In addition, it can also be integrally formed on the first connecting rod 3 .

[0040] A first bayonet 3c is also formed on the first connecting rod 3. When the seat pan 2 is in the folded state, the output gear 5a can abut against the first bayonet 3c to protect the output gear 5a.

[0041] In this embodiment, the driving assembly 5 can be driven by a motor to drive the gear plate, or it can be driven by a motor to drive the angle adjuster. Figure 3 At this time, there is no need to additionally install an arc-shaped tooth plate 3a on the first connecting rod 3, and there is no need to form a first bayonet 3c for limiting the position.

[0042] Of course, the driving component 5 is not limited to the above two driving modes, which are not listed here one by one.

[0043] Embodiment 2:

[0044] like Figure 6As shown, a cockpit layout structure includes a main driving seat A, a co-pilot seat B, and a first rear passenger seat C, a second rear passenger seat D and a third rear passenger seat E. A central armrest box F is also provided between the main driving seat A and the co-pilot seat B, wherein the second rear passenger seat D is the variable rear middle seat introduced in Example 1. The variable rear middle seat can be driven forward to dock with the central armrest box F to form a storage table, and the interior of the car cockpit is transformed from a traditional two-three layout to a more business-like two-two layout.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
