Technical Field

[0001] The invention relates to the technical field of electric vehicle accessories, in particular to a drawable and foldable backrest for a two-wheeled electric vehicle. Background Art

[0002] Two-wheeled electric vehicles are an easy-to-use means of transportation that brings great convenience to people's travel. At present, the seat cushions of most two-wheeled electric vehicles are covered with waterproof fabrics such as artificial leather to prevent the sponge in the seat cushion from absorbing water and getting damp on rainy days. However, the waterproof fabric outside the seat cushion lacks protection. When the two-wheeled electric vehicle is parked outdoors, dust, water or bird droppings are easily accumulated on the seat cushion. In addition, in summer, the seat cushion will become hot when exposed to light for a short period of time, causing great inconvenience to the user's riding. In addition, exposure to the sun will seriously affect the service life of the waterproof fabric of the seat cushion. For this reason, we propose a retractable and foldable backrest for a two-wheeled electric vehicle to provide protection for the seat cushion of the electric vehicle. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figures 1 to 4In an embodiment of the present invention, a two-wheeled electric vehicle has a retractable and foldable backrest, comprising a tail frame 1 fixedly mounted behind a seat cushion of the two-wheeled electric vehicle 17, a plurality of mounting seats 16 fixedly connected to the tail frame 1, two guide rails 3 fixedly mounted on the tail frame 1, the two guide rails 3 are commonly connected with an outer U-shaped cover 5, and the outer U-shaped cover 5 can slide and rotate on the two guide rails 3, an inner U-shaped cover 11 is slidably mounted on the inner side of the outer U-shaped cover 5, and the width dimensions of the outer U-shaped cover 5 and the inner U-shaped cover 11 are greater than the width dimension of the seat cushion.

[0018] The present invention adopts the above scheme. When in use, the tail frame 1 is fixedly mounted on the tail end of the seat cushion of the two-wheeled electric vehicle 17 by using the cooperation of the bolts and the mounting seat 16. When the two-wheeled electric vehicle 17 is parked, the outer U-shaped cover 5 is turned over and the height is adjusted on the two guide rails 3, and the inner U-shaped cover 11 is pulled out from the outer U-shaped cover 5. The outer U-shaped cover 5 and the inner U-shaped cover 11 can be placed on the seat cushion of the two-wheeled electric vehicle 17 to protect the seat cushion from dust, rain and sun, and prevent bird droppings from falling on the seat cushion, so that the user can ride at any time, and the service life of the waterproof fabric of the seat cushion can be extended. When the two-wheeled electric vehicle 17 needs to be used, the inner U-shaped cover 11 is put into the outer U-shaped cover 5, and the outer U-shaped cover 5 is flipped and height-adjusted on the two guide rails 3, so that the inner U-shaped cover 11 and the outer U-shaped cover 5 can be erected on the rear end outside of the seat cushion, which will not interfere with the opening and closing of the seat cushion (some two-wheeled electric vehicles 17 have storage space under the seat cushion, and the seat cushion needs to be opened to take and put items), and when riding the electric vehicle, the erected inner U-shaped cover 11 can be used as a backrest. In addition, in order to improve the comfort of using the inner U-shaped cover 11 as a backrest, a soft backrest bag can be installed on the inner side of the U-shaped cover 11.

[0019] Specific combination Figure 1-3 In one embodiment of the present invention, the guide rail 3 is penetrated by a first slide groove 4, the rear end of the outer U-shaped cover 5 is fixedly connected to a rotating shaft 7 through two connecting seats 6, and both ends of the rotating shaft 7 pass through the corresponding first slide groove 4 and are fixedly connected to a limiting block 8.

[0020] Through the cooperation between the first slide groove 4 and the rotating shaft 7 , it is convenient to flip and adjust the lifting of the outer U-shaped cover 5 on the two guide rails 3 .

[0021] Specific combination Figure 2 On the basis of the previous embodiment, further, an opening groove 9 is provided at the rear end of the outer U-shaped cover 5 and at the corresponding positions of the two guide rails 3. By setting the opening groove 9, the guide rail 3 can avoid interfering with the flipping of the outer U-shaped cover 5.

[0022] Specific combination Figure 1-3In one embodiment of the present invention, the outer walls on both sides of the outer U-shaped cover 5 are provided with second slide grooves 10, and guide pins 13 are movably inserted into the second slide grooves 10, and one end of the guide pins 13 located in the outer U-shaped cover 5 is fixedly connected to the inner U-shaped cover 11.

[0023] Through the cooperation between the second slide groove 10 and the guide pin 13 , the inner U-shaped cover 11 can be guided on the outer U-shaped cover 5 , so that the movement of the inner U-shaped cover 11 is more stable.

[0024] Specific combination Figure 1 In one embodiment of the present invention, a fence 2 is fixedly installed on the top of the tail frame 1, the top of the guide rail 3 is fixedly connected to the fence 2, and a first buckle 14 is fixedly installed on the outer wall of the outer U-shaped cover 5, and the hook of the first buckle 14 is adapted to the fence 2.

[0025] After the inner U-shaped cover 11 and the outer U-shaped cover 5 are erected behind the seat cushion, the hook of the first buckle 14 is matched with the fence 2 to lock the outer U-shaped cover 5 on the tail frame 1, thereby preventing the U-shaped cover 5 from turning over or moving during the riding of the vehicle, thereby ensuring the safety of use.

[0026] Specific combination Figure 1 On the basis of the previous embodiment, further, a handle 12 is fixedly installed at the front end of the outer wall of the inner U-shaped cover 11, and a second buckle 15 is fixedly installed on the outer wall of the outer U-shaped cover 5, and the hook of the second buckle 15 is adapted to the front end of the inner U-shaped cover 11.

[0027] The setting of the handle 12 facilitates the pulling and pulling operation of the inner U-shaped cover 11. By hooking the hook of the second buckle 12 on the front end of the inner U-shaped cover 11, the inner U-shaped cover 11 can be locked in the outer U-shaped cover 5 to prevent the inner U-shaped cover 11 from extending out of the outer U-shaped cover 11 during riding of the vehicle.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
