Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a gap covering structure after an automobile seat is transformed into a bed. Background Art

[0002] As people's demands for car seat comfort and functionality continue to rise, some large SUVs and commercial vehicles have introduced large bed rest modes to facilitate reclining and resting. In the current automotive industry, reclining and resting functions are usually achieved in the following ways: one is to lay the seat back flat, and the other is to assemble multiple seats together. Obviously, the former has a shorter bed structure and cannot accommodate users of different body shapes, while the latter is cumbersome to operate and the assembled bed is less comfortable.

[0003] To address these needs, companies are actively developing technologies that can directly transform entire chairs into beds. The current main concept involves creating a double-layered seat cushion. By tilting the backrest forward to the front of the seat cushion, and then flipping the double-layered cushion over and unfolding it, the surface area is expanded, ensuring the feasibility of the seat's transformation into a bed. However, to ensure the overall aesthetics of the seat, the front of the seat cushion is typically designed with an arc-shaped structure. Therefore, when the backrest is tilted forward to the front of the seat cushion, a gap exists between the backrest and the front of the seat cushion, preventing a complete fit and affecting the aesthetics and comfort of the seat when transformed into a bed. If, in order to ensure a perfect connection between the backrest and the front of the seat cushion, the front of the seat cushion is forced to be flush, the overall aesthetics of the seat will be greatly diminished. Utility Model Content

[0004] In view of this, the present invention provides a gap covering structure after the car seat is transformed into a bed, which can cover the gap between the rear end of the backrest and the front end of the seat cushion when the backrest is folded forward to the front end of the seat cushion.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A gap covering structure after a car seat is transformed into a bed, the key of which is that it includes: a base, a seat cushion is provided on the base, a backrest is arranged at the rear end of the seat cushion, a driving mechanism is provided between the backrest and the base, the driving mechanism can make the backrest fall forward and connect with the front end of the seat cushion, and a shielding component is connected to the lower part of the backrest. When the backrest falls forward and is flattened at the front end of the seat cushion, the shielding component can cover the gap between the backrest and the seat cushion.

[0007] With the above structure, when the backrest is folded forward and flattened onto the front end of the seat cushion, the shielding component can cover the upper side between the rear end of the backrest and the front end of the seat cushion, thereby achieving the purpose of blocking the gap, avoiding forcing the front end of the seat cushion to be designed into a flush shape, and improving the aesthetics of the seat after it becomes a bed.

[0008] Preferably, the shielding component includes an inner lining plate and a face cover wrapped around the outer side of the inner lining plate, the upper end of the face cover is connected to the lower end of the back side of the backrest, and when the car seat is in a sitting mode, the shielding component is suspended at the lower end of the back side of the backrest.

[0009] Preferably, the face cover is made of leather.

[0010] Preferably, the upper end of the face cover is connected to the lower end of the back side of the backrest by a zipper.

[0011] Preferably, the upper end of the face cover is connected to the lower end of the back side of the backrest through buttons.

[0012] Preferably, the upper end of the face cover is connected to the lower end of the back side of the backrest by sewing.

[0013] Preferably, the upper end of the face cover is connected to the lower end of the back side of the backrest via a bristle belt.

[0014] Preferably, the shielding component is a flexible covering component, the upper end of which is connected to the lower end of the back side of the backrest.

[0015] Preferably, the shielding component is a rectangular structure, and is extended along the width direction of the backrest.

[0016] Preferably, the driving mechanism includes a swing arm arranged on the side of the backrest, the swing arm extends toward the base, and the lower end of the swing arm is rotatably connected to the base. The swing arm rotates forward relative to the base, so that the backrest can be tilted forward and connected to the front end of the seat cushion.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By adopting the gap covering structure after the car seat is transformed into a bed provided by the utility model, when the backrest is folded forward and flat on the front end of the seat cushion, the shielding component can cover the upper side between the rear end of the backrest and the front end of the seat cushion, thereby achieving the purpose of shielding the gap, avoiding the need to design the front end of the seat cushion into a flush shape, and improving the aesthetics of the seat after it is transformed into a bed.

[0019] 2. The gap covering structure provided by the present invention after the car seat is transformed into a bed, when the backrest is flattened at the front end of the seat cushion, the shielding component touches the seat cushion, which can force the shielding component to flip upward around its upper end, thereby preventing the shielding component from obstructing the forward movement of the backrest and ensuring the smoothness of the backrest movement; when the backrest is flattened at the front end of the seat cushion, the upper structure of the seat cushion flips backward relative to the lower structure, which can also prevent the shielding component from interfering with the movement of the upper structure. Thereafter, the distal end of the shielding component can fall due to gravity so that the shielding component covers the upper side between the rear end of the backrest and the front end of the lower structure, thereby blocking the gap between the backrest and the lower structure.

[0024] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0025] like Figure 1 and 2 As shown, a gap covering structure after a car seat is transformed into a bed comprises a base 1, a seat cushion 2 is provided on the base 1, a backrest 3 is arranged at the rear end of the seat cushion 2, and a driving mechanism is provided between the backrest 3 and the base 1. Figure 3 , the driving mechanism can drive the backrest 3 to fall forward and connect to the front end of the seat cushion 2. A downwardly extending shielding component 4 is connected to the lower part of the backrest 3. When the backrest 3 falls forward and connects to the front end of the seat cushion 2, the shielding component 4 can cover the gap between the backrest 3 and the seat cushion 2. In this embodiment, the seat cushion 2 is a double-layer structure design, which includes a lower structure 21 and an upper structure 22. A flipping driving device is provided between the lower structure 21 and the upper structure 22. In the sitting state, the lower structure 21 and the upper structure 22 are arranged in an overlapping manner. When the seat is transformed into a bed, the flipping driving device can drive the upper structure 22 to flip backward relative to the lower structure 21 to a horizontal state. At this time, the shielding component 4 can cover the gap between the rear end of the backrest 3 and the front end of the lower structure 21. The flipping drive device includes a fixed gear fixed at the rear end of the lower structure 21, a revolving gear rotatably installed at the rear end of the upper structure 22, and a driver. The fixed gear is engaged with the revolving gear. The driver can drive the revolving gear to rotate around the circumference of the fixed gear to drive the upper structure 22 to rotate around the rear end of the lower structure 21, thereby causing the upper structure 22 to flip backward relative to the lower structure 21 to a horizontal state.

[0026] Based on the above structural design, when the backrest 3 is folded forward onto the front end of the seat cushion 2 and the upper structure 22 is flipped backward relative to the lower structure 21, the shielding component 4 can cover the upper side between the rear end of the backrest 3 and the front end of the lower structure 21, thereby achieving the purpose of blocking the gap, avoiding forcing the front end of the seat cushion 2 to be designed into a flush shape, and improving the aesthetics of the seat after it becomes a bed.

[0027] In this embodiment, the shielding component 4 is a rectangular structure, which is extended along the width direction of the backrest 3, so that when the shielding component 4 covers the upper side between the backrest 3 and the lower structure 21, the upper side of the shielding component 4 can form a whole with the upper side of the backrest 3 and the lower structure 21, so as to ensure that the surface of the seat can be neat and flat after it becomes a bed.

[0028] In this embodiment, the shielding member 4 is a flexible covering member, the upper end of which is connected to the lower end of the backrest 3. This design allows the flexible shielding member 4 to adaptively deform during the tilting of the backrest 3 and the rotation of the upper structure 22, avoiding interference with the seat cushion 2 and ensuring smooth movement of the backrest 3 and upper structure 22. When the upper structure 22 is tilted rearward, the shielding member 4 returns to its original position, covering the upper portion between the rear end of the backrest 3 and the front end of the lower structure 21.

[0029] For further information, see Figure 4 The shielding member 4 includes an inner lining plate 4a and a face cover 4b wrapped around the outer side of the inner lining plate 4a. The upper end of the face cover 4b is connected to the lower end of the backrest 3. Figure 2 It can be seen that when the car seat is in the sitting position, the shielding component 4 is suspended at the lower end of the back side of the backrest 3. This design allows the shielding component 4 to contact the seat cushion 2 when the backrest 3 is flattened against the front end of the seat cushion 2, forcing the shielding component 4 to flip upward around its upper end, preventing the shielding component 4 from obstructing the forward movement of the backrest 3. When the backrest 3 is flattened against the front end of the seat cushion 2 and the upper structure 22 of the seat cushion 2 flips backward relative to the lower structure 21, the shielding component 4 is also prevented from interfering with the movement of the upper structure 22. Thereafter, the distal end of the shielding component 4 can fall under the force of gravity and cover the upper side between the rear end of the backrest 3 and the front end of the lower structure 21, thereby blocking the gap between the backrest 3 and the lower structure 21.

[0030] In this embodiment, the cover 4b is made of leather, or other materials that are the same as the cover of the backrest 3.

[0031] In this embodiment, the upper end of the face cover 4b can be connected to the lower end of the back side of the backrest 3 by a zipper, or connected to the lower end of the back side of the backrest 3 by buttons, or connected to the lower end of the back side of the backrest 3 by sewing, or adhered to the lower end of the back side of the backrest 3 by a material with adhesive function such as a bristle tape.

[0032] like Figure 2 and 3As shown, the drive mechanism includes a swing arm 5 disposed on the side of the backrest 3. The swing arm 5 extends toward the base 1, and the lower end of the swing arm 5 is rotatably connected to the base 1. The swing arm 5 rotates forward relative to the base 1, which can cause the backrest 3 to tilt forward and connect to the front end of the seat cushion 5. In this embodiment, the backrest 3 can be manually tilted forward to the front end of the seat cushion 2, or the lower end of the swing arm 5 can be driven by an electric recliner to rotate forward around the base 1, driving the upper end of the swing arm 5 to rotate forward with the lower end of the swing arm 5 as the rotation center, thereby driving the backrest 3 at the upper end of the swing arm 5 to tilt forward to the front end of the seat cushion 2.

[0033] 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 various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
