Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and more specifically, to a folding seat cushion for the front passenger seat. Background Technology

[0002] The folding passenger seat cushion is a seat component that uses a mechanical structure to achieve the folding function and improve space flexibility. It is commonly found in family MPVs and commercial vehicles (trucks). Its core advantage is to expand the interior space and adapt to various needs.

[0003] Currently, folding passenger seat cushions, when folded, not only make reasonable use of the space at the bottom of the cushion to place items, but also increase the operating space inside the vehicle and improve passenger accessibility, offering good spatial flexibility. However, existing folding passenger seat cushions require passengers to manually hold the seat when folding, making it difficult to keep the seat folded, which is inconvenient to use. Therefore, this utility model proposes a folding passenger seat cushion. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a folding seat cushion for the front passenger seat, which aims to solve the problem that when the front passenger seat cushion is folded, the passengers in the vehicle need to manually hold the seat, making it impossible to keep the seat in the folded state, and thus it is not convenient to use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A folding passenger seat cushion includes a fixed frame and a backrest. The backrest is fixedly connected to the fixed frame. A connecting frame is rotatably connected to the fixed frame. A folding pad is fixedly connected to the connecting frame, and the folding pad corresponds to the backrest. A first connecting member is movably hinged to the bottom of the connecting frame. A second connecting member is movably hinged to the fixed frame, and the second connecting member is movably hinged to the first connecting member. A guide protrusion is provided on the first connecting member, and the guide protrusion is located inside the second connecting member. A mounting post is rotatably connected to the movable hinge of the first and second connecting members. A torsion spring assembly is sleeved on the circumferential surface of the mounting post, and the two lever arms of the torsion spring assembly are located inside the first and second connecting members, respectively.

[0009] As a preferred embodiment of this utility model, a support block assembly is fixedly connected to the fixing frame, and the bottom end of the folding pad corresponds to the support block assembly.

[0010] In a preferred embodiment of this utility model, a fixing plate assembly is fixedly connected to the fixing frame, and the connecting frame is rotatably connected to the fixing plate assembly.

[0011] As a preferred embodiment of this utility model, the bottom end of the connecting frame is fixedly connected to a connecting piece group, and the first connecting member is movably hinged to the connecting piece group.

[0012] As a preferred embodiment of this utility model, a fixing plate group is fixedly connected to the fixing frame, and the second connecting member is movably hinged to the fixing plate group.

[0013] 3. Beneficial Effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) In this scheme, the torsion spring group applies force to the first connector and the second connector. Through the guiding action of the guide protrusion, an upward force is formed at the hinge of the first connector and the second connector, so that the folding pad can be kept in a horizontal state for passengers to sit on. When the space inside the vehicle needs to be adjusted, the folding pad is pushed upward. The folding pad drives the connecting frame to rotate, so that the first connector pushes the second connector to fold. During the folding process of the first connector and the second connector, the guide protrusion is rotated, eliminating the guiding effect of the guide protrusion in the second connector. The torque of the torsion spring group acts on the folding hinge direction of the first connector and the second connector, that is, the front upper part of the fixed frame, so that the first connector and the second connector remain stable in the folded state, so that the connecting frame drives the folding pad to remain in the folded state. When folding, passengers do not need to hold the seat for a long time, making it more convenient to use in the vehicle. Attached Figure Description

[0027] Example:

[0028] Please see Figure 1-6A folding passenger seat cushion includes a fixed frame 1 and a backrest 2. The backrest 2 is fixedly connected to the fixed frame 1. A connecting frame 3 is rotatably connected to the fixed frame 1. A folding pad 4 is fixedly connected to the connecting frame 3, and the folding pad 4 corresponds to the backrest 2. A first connecting member 5 is movably hinged to the bottom of the connecting frame 3. A second connecting member 6 is movably hinged to the fixed frame 1, and the second connecting member 6 is movably hinged to the first connecting member 5. A guide protrusion 7 is provided on the first connecting member 5, and the guide protrusion 7 is located inside the second connecting member 6. A mounting post 8 is rotatably connected to the movable hinge of the first connecting member 5 and the second connecting member 6. A torsion spring assembly 9 is sleeved on the circumferential surface of the mounting post 8, and the two ends of the torsion spring assembly 9 are located inside the first connecting member 5 and the second connecting member 6, respectively.

[0029] In this embodiment, the fixed frame 1 is fixed inside the vehicle, and the backrest 2 and folding cushion 4 cooperate to provide seating for passengers. The connecting frame 3 allows the folding cushion 4 to be rotatably connected to the fixed frame 1, enabling stable folding. When passengers need to sit, they press down on the folding cushion 4, causing it to rotate to a horizontal position on the fixed frame 1 via the connecting frame 3. As the connecting frame 3 rotates the folding cushion 4, the first connecting piece 5 follows the rotation of the connecting frame 3, pulling the second connecting piece 6 to rotate on the fixed frame 1. Simultaneously, the torsion spring assembly 9 applies force to the first connecting piece 5 through the lever arms at both ends. Within the first connecting member 5 and the second connecting member 6, the guide protrusion 7 on the first connecting member 5 serves a guiding function, causing the first connecting member 5 to lift the second connecting member 6 during the pulling process. This ensures that the torque of the torsion spring assembly 9 acts on the hinge of the first connecting member 5 and the second connecting member 6, forming an upward force. This keeps the first connecting member 5 and the second connecting member 6 at their current angle. After the angle of the first connecting member 5 and the second connecting member 6 is fixed, the folding pad 4 remains horizontal on the fixing frame 1 for passengers to sit on. When the folding pad 4 needs to be folded to adjust the interior space, it is folded upwards. When the pad 4 is folded, the thrust overcomes the torque of the torsion spring assembly 9. The folding pad 4 drives the connecting frame 3 to rotate. The connecting frame 3 pushes the second connecting piece 6 through the first connecting piece 5, causing the first connecting piece 5 and the second connecting piece 6 to fold together. During the folding process, the angle of the guide protrusion 7 on the first connecting piece 5 changes, canceling the upward guide lifting of the second connecting piece 6. Without the guide, after the first connecting piece 5 and the second connecting piece 6 are folded, the torsion spring assembly 9 applies force to the folding direction at the hinge of the first connecting piece 5 and the second connecting piece 6, keeping the first connecting piece 5 and the second connecting piece 6 in the folded state. This stabilizes the folding pad 4 in the folded state, eliminating the need for passengers to manually hold the folding pad 4, making the folding of the seat cushion more convenient. In the folded state, the torsion spring assembly 9 applies force to the hinge of the first connecting piece 5 and the second connecting piece 6. At this time, the direction of the force is the upper front of the fixing frame 1, keeping the first connecting piece 5 and the second connecting piece 6 in the folded state. The mounting post 8 is used to limit the torsion spring assembly 9, ensuring that the torsion spring assembly 9 works stably between the first connecting piece 5 and the second connecting piece 6.

[0030] Specifically, a support block assembly 10 is fixedly connected to the fixed frame 1, and the bottom end of the folding pad 4 corresponds to the support block assembly 10.

[0031] In this embodiment, when the folding pad 4 is rotated to a horizontal position for passengers to sit on, the bottom of the folding pad 4 will contact the support block group 10. The support block group 10 can provide buffer support for the folding pad 4 to avoid impact damage between the folding pad 4 and the fixing frame 1.

[0032] Specifically, a fixed plate assembly 11 is fixedly connected to the fixed frame 1, and the connecting frame 3 is rotatably connected to the fixed plate assembly 11.

[0033] In this embodiment, the connecting frame 3 is rotatably connected to the fixed frame 1 via the fixed plate assembly 11. The fixed plate assembly 11 raises the rotation point of the connecting frame 3, leaving sufficient space for the rotation and folding of the connecting frame 3 and the folding pad 4.

[0034] Specifically, the bottom end of the connecting frame 3 is fixedly connected to the connecting piece group 12, and the first connecting piece 5 is movably hinged to the connecting piece group 12.

[0035] In this embodiment, the bottom of the connecting frame 3 is hinged to the first connecting member 5 through the connecting piece group 12, leaving enough space for the folding of the first connecting member 5.

[0036] Specifically, a fixed plate group 13 is fixedly connected to the fixed frame 1, and the second connecting member 6 is movably hinged to the fixed plate group 13.

[0037] In this embodiment, the fixing frame 1 is hinged to the second connector 6 through the fixing piece group 13, so that the second connector 6 can be folded stably.

[0038] Working principle: When the folding cushion 4 needs to be unfolded for use inside the vehicle, pressing down on the folding cushion 4 causes the connecting frame 3 to rotate on the fixed frame 1. During the rotation of the connecting frame 3, the first connecting piece 5 pulls the second connecting piece 6. At the same time, the guide protrusion 7 on the first connecting piece 5 gradually lifts the second connecting piece 6. The torque of the torsion spring assembly 9 acts on the first connecting piece 5 and the second connecting piece 6. According to the guidance of the guide protrusion 7, an upward force is formed at the hinge of the first connecting piece 5 and the second connecting piece 6, thereby keeping the first connecting piece 5 and the second connecting piece 6 stable in the unfolded state. The connecting frame 3 makes the folding cushion 4 horizontal on the fixed frame 1. The folding cushion 4, together with the backrest 2, provides comfort for the people inside the vehicle. The staff provides seating positions. When it is necessary to fold the folding pad 4 to adjust the interior space, the folding pad 4 is pushed upwards. The folding pad 4 rotates upwards through the connecting frame 3. The connecting frame 3 pushes the second connecting piece 6 through the first connecting piece 5. The rotation of the first connecting piece 5 cancels the guide protrusion 7 from guiding and lifting the second connecting piece 6, so that the first connecting piece 5 and the second connecting piece 6 form a fold. The folding direction of the first connecting piece 5 and the second connecting piece 6 is in front and above the fixed frame 1. The torsion spring group 9 applies force to the folding hinge of the first connecting piece 5 and the second connecting piece 6, so that the first connecting piece 5 and the second connecting piece 6 remain stable in the folded state, thereby keeping the connecting frame 3 and the folding pad 4 stable in the folded state and adjusting the interior space.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
