Description

Technical Field

[0001] This utility model relates to the field of electric four-wheeled vehicle technology, specifically to a foldable rear seat for an electric four-wheeled vehicle. Background Technology

[0002] Senior electric four-wheelers (also known as "elderly mobility scooters" or "low-speed electric four-wheelers") are short-distance mobility tools designed specifically for the elderly or people with mobility impairments, and usually fall under the category of low-speed electric vehicles (LSEVs). They are characterized by simple operation, low speed, and affordable price, making them suitable for everyday activities such as grocery shopping, picking up children, and short trips within the community.

[0003] Currently, the rear seats of electric four-wheeled vehicles for the elderly are supported and fixed at the bottom by support legs, with a panel in front of the base to cover the seat and increase its aesthetics. However, the interior space of these vehicles is already small, and the fixed seat cushions in the rear make them less flexible in use. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing a foldable rear seat for an electric four-wheeled vehicle. The seat cushion of the rear seat of the electric four-wheeled vehicle is designed to be foldable and retractable. When not carrying passengers, it can be folded away to free up more space for storing items, thus making reasonable use of the interior space and increasing the convenience of use. When passengers are needed, it can be laid flat for flexible use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable rear seat for an electric four-wheeled vehicle includes a backrest and a seat cushion. The two ends of the backrest are connected to the vehicle body via support columns. The seat cushion is connected to the support columns via a pivot. The lower end of the seat cushion is connected to a foldable support leg. The bottom of the seat cushion is provided with a pull ring. The seat cushion is provided with a pull rope connected to the pull ring. The back of the backrest is provided with a hook. When the seat cushion is upright, the pull ring and the hook cooperate to fix the seat cushion in place via the pull rope.

[0007] Preferably, the lower end of the support column is provided with a fixing plate, which is connected to the vehicle body by bolts.

[0008] Preferably, the side wall of the support column is provided with an ear plate, which is connected to the seat cushion through a pivot.

[0009] Preferably, the support leg is connected to the seat cushion via a self-locking hinge.

[0010] Preferably, the seat cushion is provided with a protective tube, the end of the protective tube is provided with a limiting hole, the bottom of the seat cushion is provided with a rope hole, the pull rope passes through the rope hole and the limiting hole and is connected to an elastic rope, and one end of the elastic rope is fixed to the seat cushion.

[0011] Preferably, the end of the elastic rope connected to the pull rope is provided with a limiting ring.

[0012] Preferably, the elastic rope is an elastic band.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets the seat cushion of the rear seat of the electric four-wheeled vehicle to be foldable and retractable. When not carrying passengers, it can be folded and stored to free up more space for storing items, realizing the rational use of the interior space and increasing the convenience of use; when passengers need to be carried, it can be laid flat for use, making it flexible.

[0015] 2. This utility model has a pull ring at the bottom of the seat cushion. The seat cushion can be folded and fixed by pulling the rope. The rope is automatically retracted under the action of the elastic rope, making it convenient to use.

[0016] 3. This utility model uses self-locking hinges to connect the support legs, making it easy to store, providing firm support, and convenient to use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, a foldable rear seat of an electric four-wheeled vehicle includes a backrest 1 and a seat cushion 3. Both the backrest 1 and the seat cushion 3 have an aluminum alloy or steel frame. The two ends of the backrest 1 are connected to the vehicle body via support columns 2. The seat cushion 3 is connected to the support columns 2 via a pivot. The seat cushion 3 is close to the backrest 1, and the lower end of the seat cushion 3 is connected to a foldable support leg 4. Figure 4 As shown, the bottom of the seat cushion 3 is provided with a pull ring 307, and the seat cushion 3 is provided with a pull cord 304 connected to the pull ring 307. The backrest 1 is provided with a pull hook 101 on the rear side. Figure 2 , Figure 3 As shown, after the seat cushion 3 is erected, the pull ring 307 and the pull hook 101 work together to fix the seat cushion 3 in place by the pull rope 304.

[0027] The lower end of the support column 2 is provided with a fixing plate 202, which is connected to the vehicle body by bolts.

[0028] The side wall of the support column 2 is provided with an ear plate 201, which is connected to the seat cushion 3 through a pivot. After the seat cushion 3 is rotated 90°, it is pressed against the backrest 1.

[0029] The support leg 4 is connected to the seat cushion 3 via a self-locking hinge 5. Opening the self-locking hinge 5 allows the support leg 4 to rotate so that it is against the bottom of the seat cushion 3.

[0030] In this application, the support leg 4 adopts a rectangular frame structure, which can increase the support range of the seat cushion 3 and improve stability.

[0031] like Figure 5 , Figure 6 , Figure 7 As shown, to ensure that the pull cord 304 can be pulled out smoothly, a protective tube 301 is provided inside the seat cushion 3. The end of the protective tube 301 is provided with a limiting hole 305. The bottom of the seat cushion 3 is provided with a rope hole 306. The pull cord 304 passes through the rope hole 306 and the limiting hole 305 and is connected to an elastic cord 302. One end of the elastic cord 302 is fixed to the seat cushion 3. The end of the elastic cord 302 connected to the pull cord 304 is provided with a limiting ring 303. When the ring 307 is pulled, the elastic cord 302 extends, and the pull cord 304 will extend out from the seat cushion 3. When the ring 307 is engaged with the hook 101, the limiting ring 303 just reaches the limiting hole 305, which limits the deformation of the elastic cord 302, thereby holding the seat cushion 3 in place by the pull cord 304 and preventing the seat cushion 3 from falling.

[0032] The elastic cord 302 can be a round elastic band or other elastic cords.

[0033] When using the electric four-wheeled vehicle, if it needs to carry goods and the rear seats are not occupied, the seat cushion 3 can be flipped up and folded down, and then fixed with the pull rope 304. This frees up more space between the front and rear seats, making it easier to store goods and retrieve them more conveniently, thus achieving a reasonable use of the space in the electric four-wheeled vehicle.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
