Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an electric vehicle seat cushion with a backrest. Background Technology

[0002] Electric scooter seats are specifically designed for electric bicycles, electric motorcycles, or other electric vehicles. Their primary function is to provide a comfortable ride, reduce fatigue during riding, and also cushion shocks and prevent slippage. Typically, electric scooter seats are made of soft, breathable materials such as foam or memory foam, and may also feature a waterproof layer or a non-slip bottom to enhance the user experience. The reason for including a backrest pad on an electric scooter seat is that prolonged riding can easily cause pressure and fatigue in the lower back. A backrest pad provides support, helping the rider maintain a correct posture and reducing tension in the lower back muscles. Without proper support, the seat may cause the rider to hunch over, lean forward, or adopt an unnatural posture, leading to back pain. A backrest pad stabilizes the back, improves riding posture, and reduces discomfort and pain caused by improper posture.

[0003] Existing electric scooter seats are generally divided into two categories based on size: large electric scooter seats and small electric scooter seats. Small electric scooter seats, due to their smaller size, are often designed as a one-piece seat, lacking a backrest. This design can easily put excessive pressure on the user's sacrum and coccyx during long rides, potentially causing lower back pain and discomfort.

[0004] Therefore, those skilled in the art have provided an electric vehicle seat cushion with a backrest to solve the problems mentioned in the background art. Utility Model Content

[0024] 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.

[0025] Reference Figure 1 , Figure 2 , Figures 4-7 This utility model provides an embodiment of an electric vehicle seat cushion with a backrest, comprising a seat body 1 and a backrest cushion 2. Two symmetrically distributed grooves 4 are formed at the rear of the upper surface of the seat body 1. Holes 5 are formed through the bottom surfaces of both grooves 4. Rubber strips 6 are fixedly installed at the rear of the bottom surfaces of both grooves 4. Plugs 7 are fixedly installed at the upper front ends of both rubber strips 6. Two symmetrically distributed screws 3 are fixedly installed on the top surface of the backrest cushion 2. The two screws 3 movably pass through the two holes 5. Nuts 8 are threaded onto the lower ends of both screws 3. Ring washers 9 are fixedly installed at the lower ends of both holes 5. The two ring washers 9 are located between the lower ends of the two holes 5 and the upper ends of the two nuts 8. The two rubber strips 6 have the same shape as the two grooves 4, and the two plugs 7 have the same diameter as the two holes 5.

[0026] Specifically, when the user needs to install the backrest cushion 2, first lift the two rubber strips 6 upwards to remove the plug 7 from the hole 5, exposing the two holes 5. The user holds the backrest cushion 2 and inserts the two screws 3 into the two holes 5 respectively. When inserting the screws 3, the user needs to pay attention to the orientation of the backrest cushion 2, ensuring that the inclined surface of the backrest cushion 2 is aligned with the front end of the seat cushion body 1 to prevent incorrect installation. Then, after the two screws 3 are fully inserted, their lower ends will protrude from the openings at the bottom of the two holes 5 respectively. At this point, the user puts the two nuts 8 onto the two screws 3 respectively, and then uses a wrench to turn the nuts 8 until they reach the two washers 9 and stop turning. By tightening the nuts 8, the screws 3 are firmly fixed in the holes 5, thus fixing the backrest cushion 2 onto the seat cushion body 1. The two washers 9 are flat washers, which increase the contact area between the nuts 8 and the openings at the bottom of the holes 5, dispersing pressure and preventing damage.

[0027] In addition, the rubber strip 6 has the same shape as the groove 4, and can fit completely into the groove 4 to cover the hole 5, so that the surface of the cushion body 1 has integrity and improves the appearance of the cushion body 1. Secondly, the plug 7 has the same diameter as the hole 5. When the rubber strip 6 fits into the groove 4, the plug 7 will block the hole 5, thereby preventing rainwater from flowing into the hole 5 and preventing rainwater from entering the hole 5 and causing corrosion to its inner wall.

[0028] Reference Figure 4 , Figure 6 An installation component 10 is fixedly installed on the inner top surface of the seat cushion body 1.

[0029] Specifically, the mounting component 10 is a mounting structure found in existing small electric vehicles. Its main structure consists of multiple springs, connectors, a fixing plate, and bolts. The upper ends of the multiple springs are fixedly connected to the inner top surface of the seat body 1, and connectors are fixedly connected between the multiple springs, linking the fixing plate and the springs together. The fixing plate is typically a plate with an annular opening, which is used to fit onto the base support rod of the electric vehicle. Furthermore, a bolt passes through the center of the fixing plate, allowing the user to fix the seat body 1 onto the electric vehicle by tightening the bolt.

[0030] Reference Figure 2 , Figure 3 The cushion 2 includes a surface layer 201, a cushioning layer 202 at the lower end of the surface layer 201, and a bottom layer 203 at the lower end of the cushioning layer 202. The surface layer 201 is made of nylon material, the cushioning layer 202 is made of memory foam material, and the bottom layer 203 is made of ABS plastic material.

[0031] Specifically, the top layer 201 is made of nylon, which is treated with a waterproof coating. While being waterproof, it also has good breathability and a more comfortable feel. The cushioning layer 202 is made of memory foam, which can better conform to the curve of the buttocks, distribute pressure, and provide a more personalized sense of comfort. Finally, the bottom layer 203 is made of ABS plastic, which can provide stable support for the entire backrest cushion 2.

[0032] Working principle: The user fixes the seat body 1 to the electric vehicle by installing component 10. During the ride, the backrest 2 provides support for the user's sacrum and coccyx, reducing the pressure on the sacrum and coccyx during long rides.

[0033] Secondly, when the user no longer needs to use the backrest cushion 2, first release the fixing of the mounting component 10, remove the seat body 1 from the electric vehicle, then use a wrench to unscrew the two nuts 8 from the two screws 3 respectively to release the fixing of the backrest cushion 2. Then, remove the backrest cushion 2 from the seat body 1 to complete the disassembly of the backrest cushion 2. Finally, the user should push the two rubber strips 6 downwards to make them fit together with the two grooves 4 respectively. While pushing the rubber strips 6 downwards, the user should insert the two plugs 7 into the two holes 5 respectively to cover the holes 5. The seat body 1 is then stored away.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
