Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats, and in particular relates to a shielding mechanism for an avoidance hole of an automobile seat cushion. Background Art

[0002] With the continuous development of science and technology and the automobile industry, people's demand for automobile storage functions has increased. More and more automobile manufacturers have begun to pay attention to the diversity of automobile storage, striving to ensure that the storage features not only have sufficient quantity and space, but also are more user-friendly. Good storage space layout can effectively improve the user's sense of use and riding comfort; therefore, the diversification of storage space has also become an important indicator of the quality of modern automobile interior development. Major automobile manufacturers are also paying more and more attention to the innovation of storage space when producing and developing new models.

[0003] The rear seats of traditional cars can usually be folded forward so that the backrests are horizontal and fit closely on the seat cushions, thereby increasing the available space above the seats; but for some models that use the position of the storage seats as a passage, the space that can be vacated by such seats is still relatively small, which is not conducive to storage. The Chinese invention patent with patent number CN114714996A discloses a folding seat and a vehicle. The folding seat includes a fixed bracket, a seat cushion frame, a first connecting rod, a seat support, a second connecting rod and a linear drive device. The seat cushion frame is rotatably mounted on the fixed bracket, the first connecting rod is rotatably mounted on the seat cushion frame, the seat support is fixedly mounted on the first connecting rod and rotates with the first connecting rod, one end of the second connecting rod is rotatably mounted on the fixed bracket, and the other end is rotatably mounted on the seat support. The seat body of the linear drive device is rotatably mounted on the seat cushion frame, and its linear drive end is rotatably connected to the first connecting rod. The seat cushion frame can be folded upward by the linear drive device, thereby increasing the storage space of the seat, especially the second row of seats in the vehicle. However, after the seat cushion of the folding seat is folded, parts such as the seat support are exposed, affecting the exquisite appearance of the seat. Utility Model Content

[0004] The utility model aims to provide a shielding mechanism for an avoidance hole of a car seat cushion, so as to solve the problem that parts of the existing folding seat are exposed to the outside and affect the appearance of the seat.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A cover mechanism for avoiding holes in a car seat cushion comprises a frame assembly and a plastic part;

[0007] The frame assembly includes two symmetrically arranged fixed brackets, on which a seat cushion frame is rotatably mounted, and a seat cushion foam is arranged on the seat cushion frame; each fixed bracket is rotatably connected to a first connecting rod, on which a second connecting rod is rotatably connected, and the second connecting rod is rotatably mounted on the seat cushion frame; a fixed rod is arranged between the two first connecting rods, on which a linear drive device is arranged, and an output end of the linear drive device is rotatably connected to the two second connecting rods;

[0008] The plastic part includes a cover shell fixed under the seat cushion foam, the cover shell covers the outside of the frame assembly, and two avoidance holes are arranged on the cover shell; each avoidance hole is provided with a shielding block, a first shielding plate and a second shielding plate, the shielding block is fixedly mounted on an end of the second connecting rod away from the seat cushion frame, the first shielding plate is rotatably mounted on the cover shell, and two ends of the second shielding plate are rotatably connected to the shielding block and the first shielding plate respectively;

[0009] The linear drive device can make the seat cushion foam tend to a horizontal state, and the first shielding plate and the second shielding plate are folded inside the cover shell, or make the seat cushion foam tend to a vertical state, and the first shielding plate and the second shielding plate are unfolded and shield the avoidance hole.

[0010] Furthermore, a driving rod is rotatably installed between the two second connecting rods, and a second fixing part is provided on the driving rod. The linear driving device is a screw motor, and the base of the screw motor is rotatably installed on the first fixing part. The screw of the screw motor is equipped with a nut, and the nut is rotatably connected to the second fixing part.

[0011] Furthermore, the seat cushion frame includes a fixedly connected U-shaped rod and a seat frame spring, and the seat cushion foam is installed on the seat frame spring; the cross-section of the fixed bracket is U-shaped, and the two ends of the U-shaped rod are respectively rotatably installed on the outside of the two fixed brackets, and the two first connecting rods are respectively rotatably installed on the inside of the two fixed brackets.

[0012] Furthermore, third fixing members are provided on both sides of the U-shaped rod, and the two second connecting rods are hinged to the two third fixing members respectively.

[0013] Furthermore, a control switch is provided on the side of the cover shell, and the control switch is electrically connected to the linear drive device.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] The direction of rotation of the screw of the screw motor can be controlled by controlling the control switch. When the screw rotates forward, the nut moves along the screw in the direction away from the machine base, and the nut drives the driving rod to rotate through the second fixing member, so that the lower ends of the two second connecting rods rotate into the cover shell and fold inside the cover shell, and the shielding block rotates with the second connecting rod, and pulls the first shielding plate and the second shielding plate to relatively unfold and cover the avoidance hole of the cover shell. At the same time, the second connecting rod drives the two first connecting rods and the U-shaped rod to rotate upward with the fixed bracket as the center, and finally makes the skeleton assembly tend to a vertical state, and the seat cushion is against the seat back; when the screw is reversed, the nut moves along the screw in the direction close to the machine base, and the nut drives the lower ends of the two second connecting rods to rotate outside the avoidance hole through the driving rod. At the same time, the first shielding plate and the second shielding plate are relatively folded and stored in the cover shell, and the first connecting rod and the U-shaped rod rotate downward with the fixed bracket as the center, and finally makes the skeleton assembly tend to a horizontal state.

[0016] The utility model arranges a shielding block, a first shielding plate and a second shielding plate between the cover shell and the seat cushion frame. When the seat cushion tends to be in a vertical state, the shielding block, the first shielding plate and the second shielding plate can automatically unfold and cover the avoidance hole on the cover shell, thereby making the entire seat cushion bottom smoother and more beautiful, avoiding the seat cushion frame inside the cover shell from being exposed to the outside, and effectively improving the exquisite appearance of the seat assembly.

[0025] Example

[0026] A cover mechanism for avoiding holes in a car seat cushion comprises a frame component and a plastic part.

[0027] like Figure 1-5 As shown, the skeleton assembly includes two symmetrically arranged fixed brackets 1, the cross-section of the fixed brackets 1 is U-shaped, and a seat cushion skeleton 2 is rotatably installed on the two fixed brackets 1. The seat cushion skeleton 2 includes a U-shaped rod 21 and a seat frame spring 22 that are fixedly connected. A seat cushion foam 3 is installed on the seat frame spring 22. The two ends of the U-shaped rod 21 are rotatably installed on the outer sides of the two fixed brackets 1, and third fixing members 211 are welded and fixed on both sides of the U-shaped rod 21; the inner sides of the two fixed brackets 1 are rotatably connected to a first connecting rod 4, each of the first connecting rods 4 is rotatably connected to a second connecting rod 5, and the upper ends of the two second connecting rods 5 are rotatably installed Installed on the third fixing member 211 on both sides of the U-shaped rod 21; a fixing rod 41 is provided between the two first connecting rods 4, and a linear driving device is provided on the fixing rod 41. The linear driving device of this embodiment is a screw motor 6. A first fixing member 42 is welded and fixed on the fixing rod 41, and a base 61 of the screw motor 6 is rotatably installed on the first fixing member 42. A nut 63 is matched on the screw 62 of the screw motor 6; a driving rod 51 is rotatably installed between the lower ends of the two second connecting rods 5, and a second fixing member 52 is welded and fixed on the driving rod 51, and the second fixing member 52 is rotatably connected to the nut 63 of the screw motor 6.

[0028] like Figure 1-5 As shown, the plastic part includes a cover shell 7 fixed under the seat cushion foam 3, the cover shell 7 covers the outside of the skeleton assembly, and two avoidance holes are provided on the cover shell 7; each avoidance hole is provided with a shielding block 71, a first shielding plate 72 and a second shielding plate 73, the shielding block 71 is fixedly mounted on the end of the second connecting rod 5 away from the U-shaped rod 21, the first shielding plate 72 is rotatably mounted on the cover shell 7, and the two ends of the second shielding plate 73 are rotatably connected to the shielding block 71 and the first shielding plate 72 respectively; a control switch 8 is provided on the side of the cover shell 7, and the control switch 8 is electrically connected to the screw motor 6.

[0029] The screw motor 6 can be driven by the control switch 8 to make the frame assembly tend to a horizontal state (such as Figure 1 As shown), the first shielding plate 72 and the second shielding plate 73 are folded inside the housing 7 (as shown Figure 3), or make the frame assembly tend to a vertical state (as shown Figure 2 As shown), the first shielding plate 72 and the second shielding plate 73 are unfolded and shield the avoidance hole (as shown Figure 4 shown).

[0030] The specific implementation is as follows:

[0031] The rotation direction of the lead screw 62 of the lead screw motor 6 can be controlled by controlling the switch 8. When the lead screw 62 rotates forward, the nut 63 moves along the lead screw 62 in the direction away from the machine base 61. The nut 63 drives the driving rod 51 to rotate through the second fixing member 52, so that the lower ends of the two second connecting rods 5 rotate into the cover shell 7 and fold inside the cover shell 7. The shielding block 71 rotates with the second connecting rod 5 and pulls the first shielding plate 72 and the second shielding plate 73 to expand relatively and cover the avoidance hole of the cover shell 7. At the same time, the second connecting rod 5 drives the two first connecting rods 4 and the U-shaped rod 21 to rotate upward with the fixed bracket 1 as the center, so that the skeleton assembly tends to be in a vertical state, and the seat cushion foam 3 is attached to the seat back 9 (such as Figure 2 and 4 As shown); when the lead screw 62 is reversed, the nut 63 moves along the lead screw 62 toward the machine base 61, and the nut 63 drives the lower ends of the two second connecting rods 5 to rotate outside the avoidance hole through the driving rod 51. At the same time, the first shielding plate 72 and the second shielding plate 73 are relatively folded and stored in the cover 7, and the first connecting rod 4 and the U-shaped rod 21 rotate downward with the fixed bracket 1 as the center, and finally the seat cushion foam 3 tends to a horizontal state (as shown in FIG. Figure 1 and 3 shown).

[0032] The utility model arranges a shielding block 71, a first shielding plate 72 and a second shielding plate 73 between the cover shell 7 and the seat cushion frame 2. When the seat cushion tends to be in a vertical state, the shielding block 71, the first shielding plate 72 and the second shielding plate 73 can automatically unfold and cover the avoidance hole on the cover shell 7, thereby making the entire seat cushion bottom smoother and more beautiful, avoiding exposure of the seat cushion frame 2 inside the cover shell 7, and effectively improving the exquisite appearance of the seat assembly.
