Description

Technical Field

[0001] The present invention belongs to the technical field of electric vehicles, and in particular relates to a structure comprising a flip-up rear seat of an electric vehicle, a sliding trunk and a front seat. Background Art

[0002] At present, electric vehicles have become a common means of transportation for people. Because electric vehicles are light, pollution-free and have low operating costs, they are popular among the general public. The development of the electric vehicle industry has also been greatly improved. There are many types of electric vehicles, including small, practical, foldable, etc. Different types can be selected according to different uses and preferences.

[0003] As there are many electric vehicles now, lightness and flexibility have become a trend. Electric vehicles with light weight and shorter bodies can pass more easily on crowded roads. For example, many parents currently choose to use electric vehicles to pick up their children in order to avoid traffic jams at the school gate. This not only alleviates traffic problems, but also avoids problems such as lateness caused by traffic jams. Electric vehicles with shorter body lengths are also more space-saving when stored. Some manufacturers have cancelled the trunk to make it lighter, and the length of the electric vehicle has become shorter, but the storage space of this type of electric vehicle has become smaller. If the trunk is not cancelled, the length of the seat must be shortened to achieve the purpose of reducing the length of the electric vehicle, but this reduces the passenger capacity of the electric vehicle and cannot meet the demand for carrying people.

[0004] For example, Chinese invention application number CN201710963630.2 discloses an electric vehicle seat, which includes a seat cushion and a back cushion, each of which is provided with a seat cushion arm and a back cushion arm for support, respectively; the seat cushion arm and the back cushion arm are rotatably connected to each other via a rotating shaft, and the back cushion arm is fixedly connected to rotating shaft I; a coil spring is provided on rotating shaft I, one end of the coil spring is fixedly connected to the back cushion arm, and the other end is fixedly connected to the seat cushion arm; this device can realize the folding of the electric vehicle seat, but the folded seat cushion of the electric vehicle seat still occupies a large amount of space. When it is necessary to carry a person, the back cushion occupies a certain space in the middle of the seat cushion, and the provision of the back cushion will inevitably affect the comfort of the rear seat occupants. If the electric vehicle is provided with a trunk, this seat structure cannot place the trunk in the front, and the length of the entire electric vehicle remains unchanged. During use, the problem of the electric vehicle being too long and occupying a large space still exists. To address the above problems, the present invention designs a structure including a flip-up electric vehicle rear seat, a sliding trunk, and a front seat. Summary of the Invention

[0014] The present invention is easy to operate when in use. When there is no one on board, you only need to press the push rod, which drives the push block to move, and the push block disengages the locking groove on the locking block. The rear seat can be rotated around the rotating mechanism, and the rear seat is pulled upward to a perpendicular position with the front seat. Then, you press the knob again, the rotating rod moves backward, and the limit block on the rotating rod disengages the stop plate. When the knob is rotated counterclockwise, the large gear drives the slider to move downward, and the slider drives the locking block to move downward. When the knob is rotated to 90 degrees, the locking block is completely located in the base; when the knob is rotated counterclockwise, the small gear 1 and the small gear 2 respectively drive the rack 1 and the rack 2 to move downward, and when the knob is rotated to 90 degrees, the rack 1 and the rack 2 are completely located in the base; at this time, the limit block and the cross in the stop plate The shaped through holes are located in the same horizontal direction. Loosening the knob causes the return spring to reset, driving the spring fixing plate to move. The rotating rod moves forward with the spring fixing plate, and the limit block enters the stop plate. The stop plate limits the rotation of the limit block, and the rotating rod cannot rotate at this time. At this time, the locking block, rack 1 and rack 2 are located in the base, pushing the trunk, and the slide rail moves to the left along the guide rail until the trunk touches the back seat. At this time, press the knob, and the rotating rod moves backward. The limit block on the rotating rod disengages from the stop plate. Rotate the knob clockwise, and the large gear drives the slider to move upward, and the slider drives the locking block to move upward. When the knob is rotated to 90 degrees, the locking block is located in the trunk locking hole at the bottom of the trunk, which is used to fix the trunk to prevent the trunk from sliding. When the wheel is turned 90 degrees, the locking block is completely disengaged from the lock hole of the trunk; at this time, the limit block and the cross-shaped through hole in the stop plate are in the same horizontal direction, and the return spring is reset by loosening the knob, driving the spring fixing plate to move, and the rotating rod moves forward with the spring fixing plate, and the limit block enters the stop plate. The stop plate restricts the rotation of the limit block, and the rotating rod cannot rotate at this time; when it is necessary to carry people, press the knob, the rotating rod moves backward, and the limit block on the rotating rod disengages from the stop plate. The knob is rotated counterclockwise, and the large gear drives the slider to move downward, and the slider drives the locking block to move downward. When the knob is rotated to 90 degrees, the locking block is completely disengaged from the lock hole of the trunk; at this time, the limit block and the cross-shaped through hole in the stop plate are in the same horizontal direction, and the return spring is reset by loosening the knob, driving the spring fixing plate to move, and the rotating rod moves with the spring fixing plate When the wheel is turned to the left, the gear shifts back to the left, and the stop plate retracts, and the gear shifts back to the right, which in turn pushes the wheel back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the left, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to the right, where it will engage the stop plate and the gear shifts back to theAt this time, the ends of rack 1 and rack 2 are located on the left end surface of the slide rail. At this time, the rear seat is pulled, causing it to rotate around the rotating mechanism. The rear seat rotates clockwise to a horizontal position. The push block hits the locking block and is compressed. The wedge-shaped surface of the push block is compressed and drives the push block to move backward. The rear seat is further pressed down and the push block slides to the locking groove position on the locking block. The push block slides into the locking groove under the elastic force of the return spring. The upper surface of the locking groove contacts the upper surface of the push block. The locking block is restricted in the locking groove. After the locking block is fixed, the rear seat cannot rotate, achieving the purpose of locking the rear seat.
