Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a multifunctional automotive rear seat frame. Background Technology

[0002] With the continuous advancement of the automotive industry and the increasing diversification of consumer demands, the role of rear seats in automobiles has far surpassed its basic function of providing seating, instead fulfilling multiple functional expectations such as storage, entertainment, and rest. However, traditional rear seat frame designs are often limited to a single function, making it difficult to fully respond to the urgent needs of modern consumers for diverse experiences.

[0003] In particular, with the current popularity of self-driving tours and outdoor adventure activities, consumers have placed higher demands on the flexible configuration and high comfort of car interior space. Although traditional car rear seats usually have folding or reclining functions, they often fall short when trying to create a flat and spacious resting space—such as a "double bed mode"—failing to provide an ideal resting experience. In addition, the lack of linkage design between the various components of the traditional car rear seat frame makes the seat adjustment process cumbersome and complicated, not only time-consuming and laborious, but also greatly reducing the user's ease of operation. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a multifunctional rear seat frame for automobiles to meet the diversified needs of modern consumers.

[0005] To achieve the above objectives, this utility model proposes a multifunctional rear seat frame for automobiles, including a backrest frame assembly and a seat cushion frame assembly. A backrest lock assembly is installed at the upper end of the backrest frame assembly. The backrest lock assembly is locked to a locking hook assembly on the vehicle body and can rotate around it. The backrest frame assembly is connected to the seat cushion frame assembly through a linkage mechanism. A sliding mechanism and a support mechanism are provided between the seat cushion frame assembly and the vehicle floor. The support mechanism is fixed to the vehicle floor. The sliding mechanism is hinged to the support mechanism and locked by an adjuster. The seat cushion frame assembly is slidably connected to the sliding mechanism. A seat cushion locking mechanism is also provided between the support mechanism and the linkage mechanism.

[0006] When the seat cushion locking mechanism is unlocked, the seat cushion frame assembly can slide backward, thereby driving the backrest frame assembly to move backward under the action of the linkage mechanism, so as to realize the backward movement of the entire chair; when both the seat cushion locking mechanism and the angle adjuster are unlocked, the seat cushion frame assembly can flip upward, so as to realize the seat cushion is folded up; when the backrest locking assembly is unlocked, the backrest frame assembly can flip forward, so as to realize the backrest is laid flat forward.

[0007] In the above scheme: the support mechanism includes a left fixed support assembly and a right fixed support assembly arranged opposite to each other; the sliding mechanism includes a left sliding groove assembly and a right sliding groove assembly arranged opposite to each other; the linkage mechanism includes two connecting arm assemblies arranged opposite to each other; the front ends of the left sliding groove assembly and the right sliding groove assembly are provided with sliding grooves extending forward and backward; the rear end of the left sliding groove assembly is hinged to the upper end of the left fixed support assembly; the rear end of the right sliding groove assembly is connected to the upper end of the right fixed support assembly through the angle adjuster; both ends of the seat cushion frame assembly are slidably connected to the two sliding grooves on both sides through stepped screws; and both ends of the seat cushion frame assembly are also hinged to the bottom end of the backrest frame assembly through the connecting arm assembly; the connecting arm assembly is hinged to both the backrest frame assembly and the seat cushion frame assembly.

[0008] Thanks to the coordinated action of the sliding mechanism, linkage mechanism, and angle adjuster, the seat can freely switch between the states of the seat cushion folding upwards, the seat moving backwards, and the backrest lying flat forwards, greatly enhancing the seat's flexibility and adaptability to meet the needs of use in different scenarios. Moreover, to ensure the coordinated action of the sliding mechanism, linkage mechanism, and angle adjuster, the hinge points of the left sliding groove assembly and the left fixed bracket assembly, and the hinge points of the right sliding groove assembly and the left fixed bracket assembly connected by the angle adjuster, are arranged symmetrically from left to right; the connecting arm assemblies on both sides are also arranged symmetrically from left to right, and the sliding grooves on both sides are also arranged symmetrically from left to right.

[0009] In the above solution: Both sides of the seat cushion frame assembly are provided with connecting lugs. These connecting lugs are fixed to the seat cushion frame assembly by two spaced-apart stepped screws, and are slidably limited within the corresponding side grooves by these stepped screws. The design of the connecting lugs provides additional support points for the connection between the seat cushion frame assembly and the grooves. The fixation by the two spaced-apart stepped screws ensures the stability of the seat cushion frame assembly during sliding, preventing loosening or damage due to shaking or vibration. The stepped screws not only serve a fixing function but also achieve a sliding limit function.

[0010] In the above solution: the connecting arm assembly is hinged to the corresponding side connecting lug, thereby achieving hinge connection with the seat frame assembly. The structure is simple and the assembly is convenient.

[0011] In the above solution: the seat cushion locking mechanism includes a seat cushion locking assembly fixed to the left fixed bracket assembly and a connecting arm locking hook fixed to the left connecting arm assembly. The seat cushion locking assembly is locked onto the connecting arm locking hook. The design of the seat cushion locking mechanism ensures that the seat cushion frame assembly can be stably locked after being adjusted to the required position. The mechanism has a simple structure and is easy to assemble.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through innovative linkage, sliding, support, and seat cushion locking mechanisms, the seat frame enables the seat to move backward, the seat cushion to fold up, and the backrest to flatten forward, greatly enriching the functionality of the rear seats and meeting consumers' needs for storage, entertainment, and rest. 2. When more space is needed for rest or storage, the seat cushion can fold up or the entire seat can move backward, creating a more spacious and flexible interior space, especially suitable for road trips and outdoor activities, enhancing user comfort and convenience. 3. The seat adjustment process is simpler and more intuitive. Users only need to unlock the corresponding locking mechanism to easily achieve various seat changes, greatly saving time and effort and improving efficiency. Attached Figure Description

[0021] like Figure 1 As shown in Figure 6, a multifunctional rear seat frame for automobiles mainly consists of a backrest frame assembly 1 and a seat cushion frame assembly 2. A backrest lock assembly 3 is installed at the upper end of the backrest frame assembly 1. The backrest lock assembly 3 is locked to a lock hook assembly 4 on the vehicle body and can rotate around it.

[0022] The backrest frame assembly 1 is connected to the seat cushion frame assembly 2 via a linkage mechanism 5. A sliding mechanism 6 and a support mechanism 7 are provided between the seat cushion frame assembly 1 and the vehicle floor. The support mechanism 7 is fixed to the vehicle floor, and the sliding mechanism 6 is hinged to the support mechanism 7 and locked by an adjuster 8. The seat cushion frame assembly 2 is slidably connected to the sliding mechanism 6. A seat cushion locking mechanism 9 is also provided between the support mechanism 7 and the linkage mechanism 5.

[0023] When the seat cushion locking mechanism 9 is unlocked, the seat cushion frame assembly 2 can slide backward, thereby driving the backrest frame assembly 1 to move backward under the action of the linkage mechanism 5, so as to realize the movement of the whole chair backward (the movement of the seat backward can provide space for the front seat backrest to fold back flat, so that the rear seat in this state can form a double bed mode with the front seat backrest folded back).

[0024] When both the seat cushion locking mechanism 9 and the angle adjuster 8 are unlocked, the seat cushion frame assembly 2 can flip upwards to allow the seat cushion to fold up (vertical position). When the backrest locking assembly 3 is unlocked, the backrest frame assembly 1 can flip forward to allow the backrest to lie flat forward.

[0025] Preferably, the support mechanism 7 includes a left fixed support assembly 71 and a right fixed support assembly 72 arranged opposite to each other, the sliding mechanism 6 includes a left sliding groove assembly 61 and a right sliding groove assembly 62 arranged opposite to each other, and the linkage mechanism 5 includes two connecting arm assemblies 51 arranged opposite to each other.

[0026] The front ends of the left slide rail assembly 61 and the right slide rail assembly 62 are both provided with front-to-back extending slide rails 10. The rear end of the left slide rail assembly 61 is hinged to the upper end of the left fixed bracket assembly 71. The rear end of the right slide rail assembly 62 is connected to the upper end of the right fixed bracket assembly 72 through an angle adjuster 8. Both ends of the seat cushion frame assembly 2 are slidably connected to the two slide rails 10 through step screws 11. Both ends of the seat cushion frame assembly 2 are also hinged to the bottom end of the backrest frame assembly 2 through a connecting arm assembly 51. The connecting arm assembly 51 is hinged to both the backrest frame assembly 1 and the seat cushion frame assembly 2.

[0027] Thanks to the coordinated action of the sliding mechanism 6, the linkage mechanism 5, and the adjuster 8, the seat can freely switch between the states of the seat cushion folding upwards, the seat moving backwards, and the backrest lying flat forwards, greatly enhancing the seat's flexibility and adaptability and meeting the usage needs in different scenarios. Moreover, to ensure the coordinated action of the sliding mechanism 6, the linkage mechanism 5, and the adjuster 8, the hinge points of the left sliding groove assembly 61 and the left fixed bracket assembly 71, and the hinge points of the right sliding groove assembly 62 and the left fixed bracket assembly 72 connected by the adjuster 8 are arranged symmetrically from left to right; the connecting arm assemblies 51 on both sides are also arranged symmetrically from left to right, and the sliding grooves 10 on both sides are also arranged symmetrically from left to right.

[0028] Ideally, the seat cushion frame assembly 2 has connecting lugs 12 on both sides. The connecting lugs 12 are fixed to the seat cushion frame assembly 2 by two spaced-apart stepped screws 11, and are slidably limited within the corresponding side grooves 10 by these stepped screws 11. The design of the connecting lugs 12 provides additional support points for the connection between the seat cushion frame assembly 2 and the grooves 10. The fixation by the two spaced-apart stepped screws 11 ensures the stability of the seat cushion frame assembly 2 during sliding, preventing loosening or damage due to shaking or vibration. The stepped screws 11 not only serve a fixing function but also achieve a sliding limit function.

[0029] Ideally, the connecting arm assembly 51 is hinged to the corresponding side connecting lug 12, thereby achieving hinge connection with the seat frame assembly 2, which is simple in structure and easy to assemble.

[0030] Preferably, the seat locking mechanism 9 includes a seat locking assembly 91 fixed to the left fixed bracket assembly 71 and a connecting arm locking hook 92 fixed to the left connecting arm assembly 51, with the seat locking assembly 91 locked onto the connecting arm locking hook 92. The design of the seat locking mechanism 9 ensures that the seat frame assembly 2 can be stably locked after being adjusted to the desired position. The mechanism has a simple structure and is easy to assemble.
