Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a three-folding electric sofa bed for an automobile. Background Art

[0002] MPVs (multi-purpose vehicles) evolved from station wagons, combining the spacious passenger space of a station wagon, the comfort of a sedan, and the functionality of a van. They typically have a two-box structure and can seat 7-8 people. Strictly speaking, MPVs are primarily targeted at families. Passenger vehicles converted from commercial vans for group use do not qualify as true MPVs. MPVs offer relatively more space than sedans of the same displacement, and while they do vary in size and specifications, they are not as narrow as sedans. According to the Zhiyan Data Research Center, with changes in family structures and rising fuel prices, MPVs have become a new type of vehicle for family consumption. This increase in family consumption will undoubtedly significantly accelerate the entry of MPVs into the family car market, making family purchases a new focus in the MPV market.

[0003] With the relaxation of the three-row policy, MPV models are becoming more and more popular. Currently, the three-row MPV can only fold flat with the backrest electrically. After folding flat, the connection between the backrest and the seat cushion is only 1.2 meters long. The seat length is far from enough when people are resting in the car. By folding the seat three times, the seat can be unfolded to a size of more than 1.7 meters. Utility Model Content

[0023] Example

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a three-fold electric sofa bed for a car, comprising a lower seat cushion frame 2, an upper seat cushion frame 3 and a backrest frame 1. A fixed seat is provided on the lower surface of the lower seat cushion frame 2, and a small servo motor 4 is provided on the side of the fixed seat away from the lower seat cushion frame 2. The outer surface of the small servo motor 4 abuts against a transmission box 5, and the transmission box 5 is arranged on the lower surface of the lower seat cushion frame 2. A transmission shaft 6 is rotatably connected to the inside of the transmission box 5, and an adjusting screw 7 is provided on one side of the transmission shaft 6. An adjusting sleeve 8 is transmission-connected to the outer surface of the adjusting screw 7. A connecting shaft is provided on the outer surface of the adjusting sleeve 8. A connecting shaft is rotatably connected to both ends of the connecting shaft with a V-shaped connecting rod 9. A support shaft is provided at one end of the V-shaped connecting rod 9 far from the connecting shaft, and a connecting seat 10 is provided at one end of the supporting shaft. An end of the connecting seat 10 away from the support shaft is arranged on one side of the upper seat cushion frame 3, and a first bevel gear 11 is provided at one end of the output shaft of the small servo motor 4. The outer surface of the first bevel gear 11 The surface is meshed with a second bevel gear 12, and the second bevel gear 12 is arranged on the outer surface of the transmission shaft 6. The first bevel gear 11 and the second bevel gear 12 are both located inside the transmission case 5. A limited seat 13 is provided on one side of the lower seat cushion frame 2, and a fixed shaft rod is provided on the side of the limited seat 13 away from the lower seat cushion frame 2. The outer surface of the fixed shaft rod is rotatably connected with a V-shaped connecting plate 14, and a rotating shaft 15 is provided in the middle of the V-shaped connecting plate 14. The rotating shaft 15 is rotatably connected to the middle of the V-shaped connecting rod 9. An adjusting slot 16 is provided inside the connecting seat 10, and the inside of the adjusting slot 16 is slidably connected with a sliding shaft. One side of the sliding shaft is arranged on the V-shaped connecting plate 14, and a limiting plate 17 is provided on the side of the sliding shaft away from the V-shaped connecting plate 14. The number of V-shaped connecting rods 9 is on both sides, which are symmetrically distributed on both sides of the adjustment sleeve 8. The connection structure of the connection between the backrest frame 1 and the lower seat cushion frame 2 is the same as the connection structure of the connection between the upper seat cushion frame 3 and the lower seat cushion frame 2.

[0025] During use, when the seat is used normally, the first bevel gear 11 is driven to rotate by the positive rotation of the small servo motor 4, thereby driving the second bevel gear 12 and the transmission shaft 6 to rotate, thereby driving the adjusting screw 7 to rotate positively, driving the adjusting sleeve 8 to move in the direction away from the small servo motor 4, so that the V-shaped connecting rod 9 rotates, and under the action of the V-shaped connecting plate 14 and the connecting seat 10, the upper seat cushion frame 3 is driven to rotate, so that the upper seat cushion frame 3 rotates 180 degrees around the rotating shaft 15 and folds to the upper surface of the lower seat cushion frame 2. At the same time, the rotation of the small servo motor 4 at the connection between the lower seat cushion frame 2 and the backrest frame 1 on the other side is controlled to drive the backrest frame 1 to rotate 90 degrees around the rotating shaft 15 to form the seat shape (such as Figure 1 ), when it needs to be used as a bed, the reverse rotation of the small servo motor 4 drives the first bevel gear 11 to rotate, thereby driving the second bevel gear 12 and the transmission shaft 6 to rotate, thereby driving the adjusting screw 7 to rotate in the reverse direction, driving the adjusting sleeve 8 to move in the direction of the small servo motor 4, so that the V-shaped connecting rod 9 rotates, and under the action of the V-shaped connecting plate 14 and the connecting seat 10, the upper seat cushion frame 3 is driven to rotate, so that the upper seat cushion frame 3 rotates 180 degrees in the opposite direction around the rotating shaft 15, so that the upper seat cushion frame 3 is parallel to the lower seat cushion frame 2. At the same time, the rotation of the small servo motor 4 at the connection between the lower seat cushion frame 2 and the backrest frame 1 on the other side is controlled to drive the backrest frame 1 to rotate 90 degrees in the reverse direction around the rotating shaft 15, and also parallel to the lower seat cushion frame 2, thus becoming a 1.7-meter-long sofa bed (such as Figure 5 ), at the same time, the first bevel gear 11 is driven to rotate by the forward rotation of the small servo motor 4, thereby driving the second bevel gear 12 and the transmission shaft 6 to rotate, thereby driving the adjusting screw 7 to rotate forward, driving the adjusting sleeve 8 to move in the direction away from the small servo motor 4, so that the V-shaped connecting rod 9 rotates, and under the action of the V-shaped connecting plate 14 and the connecting seat 10, the upper seat cushion frame 3 is driven to rotate, so that the upper seat cushion frame 3 rotates 180 degrees around the rotating shaft 15, folds to the upper surface of the lower seat cushion frame 2, and controls the small joint of the lower seat cushion frame 2 and the backrest frame 1 on the other side. The rotation of the servo motor 4 drives the backrest frame 1 to rotate ninety degrees in the opposite direction around the rotating shaft 15. The backrest frame 1 is parallel to the lower cushion frame 2. In this way, a large space is created in the trunk, which enables the three-fold electric sofa bed of the car to be folded flat. The multi-link mechanism is adopted to simply realize the front and rear flattening of the seats, and the three-folding seats maximize the use of the vehicle space. This frame is required for all MPV and RV seats and can be used in all MPVs and RVs. The seats can be used as beds after being folded flat, and can also be taken out separately to pull luggage (the outer surface of the frame is covered with sofa covers, not shown in the figure).

[0026] The working principle and beneficial effects of this utility model: This three-fold electric sofa bed for cars uses a multi-link mechanism to simply fold the seats flat front and back, maximizing the use of the three-fold seats in the car. This frame is required for all MPV and RV seats and is universally compatible with all MPVs and RVs. The seats can be used as a bed when folded flat and can be taken out separately to carry luggage. (When the seats are folded, the luggage compartment space is larger and the storage function is increased.)

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
