[0002] Electric bicycles, also known as "electric vehicles," are pure electric motor vehicles powered by batteries and driven by electric motors (DC, AC, series, or separately excited). In recent years, they have become very popular in my country. Electric bicycles or motorcycles typically include a seat and a base. The seat is located on the base, allowing the user to easily ride the electric bicycle or motorcycle while seated.

[0003] Existing electric vehicles, motorcycles, and shared electric bikes are typically parked outdoors for convenience. Since the seats are mostly made of rubber and often filled with foam for comfort, and are usually black, they easily absorb heat in strong sunlight and tend to accumulate water in the rain, affecting user experience. Therefore, exposure to rain, sun, and sandstorms accelerates seat damage, thus shortening the vehicle's lifespan. Existing seat covers are usually manually operated, which is inexpensive but cumbersome; there are also electrically powered covers, which are more time-saving and labor-saving but more expensive, require electricity, and are more prone to damage.

Specifically, the swing arm is located inside the cover and connected to its inner wall. More specifically, the swing arm is located on the inner wall of the first cover. The drive unit passes through the first cover and is located in the sliding groove of the third cover, slidingly connected to the sliding groove. More specifically, multiple third covers can be provided as needed. After the cover is closed, the swing arm is completely hidden inside the cover, making the product more aesthetically pleasing, preventing the swing arm from scratching other parts, and extending the product's service life.

[0033] The first elastic element 4 is connected to the swing arm 3 and has a tendency to drive the cover 2 to its second position via the swing arm 3;

[0034] The interlocking device 5 has a first position for interlocking the swing arm 3 and a second position for unlocking, allowing the swing arm 3 to move freely. The interlocking device 5 interlocks the swing arm 3 when the cover 2 is in the first position. The advantages of this invention are that the swing arm drives the cover to move, resulting in a simple structure, convenient and reliable transmission, and adaptability to different occasions. The inclusion of a first elastic element allows the swing arm to drive the cover towards closing, avoiding manual operation, simplifying the structure and reducing effort. The interlocking device prevents accidental swing arm movement. The cover on the seat cushion provides protection, extends its lifespan, and improves the user experience. This invention also features a simple structure, convenient assembly, reliable operation, and long service life. Specifically, an operating element 24 can be provided on the cover for easy hand operation of opening and closing the cover. The cover closing is manually operated; when the user stands up or the interlocking rod is unlocked, the swing arm is driven by the first elastic element to close the cover, providing protection.

[0035] The interlocking device 5 includes an interlocking rod 51, which is mounted on the mounting bracket 1. The interlocking rod 51 has an interlocking part 511, and the rocker arm 3 has an interlocking hole 33 that matches the interlocking part 511. When the cover 2 is in the first position, the interlocking part 511 is inserted into the interlocking hole 33 to interlock the rocker arm 3. This structure makes the product simple and the interlocking convenient and reliable.

[0036] This utility model also includes:

[0037] The driving component 52 has a first position under pressure and a second position that drives the interlocking rod 51 to unlock when reset; the first elastic element 4 drives the cover 2 to open for protection when the driving component 52 is in the second position via the swing rod 3.

[0038] The second elastic element 53 is disposed on the interlocking rod 51. The second elastic element 53 has a tendency to drive the interlocking rod 51 to extend for interlocking the swing arm 3. The driving element can drive the interlocking rod to move. When the user stands up (relieving the pressure), the interlocking rod can be driven to unlock. The swing arm is driven by the first elastic element to close, completing the cover action and preventing the user from forgetting to close the cover.

[0039] This utility model also includes a mounting plate 54, on which the driving member 52 is disposed; a third elastic member 55 is disposed on the mounting plate 54, and the third elastic member 55 has a tendency to drive the driving member 52 to its second position to unlock the interlocking rod 51. The mounting plate improves the overall integrity of the product, facilitates the overall installation of the product, and has a wide range of compatibility.

[0040] The driving component 52 is equipped with a driving block 521, which is located on the driving component 52. The driving block 521 and the interlocking rod 51 have mutually cooperating inclined surfaces 56. The interlocking rod 51 passes through the mounting frame 1 and is horizontally engaged with the mounting frame 1. This structure allows the driving block to reliably interlock with the horizontal movement of the electric interlocking rod. The inclined surfaces push the driving block and interlocking rod smoothly, and the interlocking rod unlocks easily and reliably. In practice, the driving block can be integrally formed with the driving component through an interference fit, or the driving block can be mounted on the driving component via a shaft. A stop shaft is provided above the driving block to limit its movement. When the driving component resets and moves to its second position, the stop shaft can block the driving block, and the driving block drives the interlocking rod to unlock. The interlocking rod is horizontally rotatable with the mounting frame, and the interlocking part and the interlocking rod can be separate structures. The horizontal rotation of the interlocking rod causes the interlocking part to move horizontally relative to the mounting frame.

[0041] This utility model also includes a counterweight 6, disposed on the swing arm 3, providing a force opposite to the swing direction of the swing arm 3 to provide cushioning. Specifically, it also includes a connecting plate 61, on which the counterweight 6 is disposed and rotates relative to the counterweight 6 and is vertically downward. The connecting plate 61 and the swing arm 3 are disposed on both sides of the mounting frame 1, and the connecting plate 61 is connected to the swing arm 3 via a connecting shaft 31. In this way, the counterweight and the swing arm swing in coordination to achieve a cushioning effect, preventing excessive movement of the product during the first elastic element drive and causing damage to the protective cover and seat cushion, thus extending the service life. Of course, a torsion spring can be installed on the swing arm to assist the swing arm movement, making operation more effortless. Specifically, both the first and second elastic elements are torsion springs.

[0042] The cover 2 includes a first cover 21 and a second cover 22, with a third cover 23 positioned between them. The first cover 21, the second cover 22, and the third cover 23 are hinged together. The first cover 21 is mounted on a mounting frame 1 and rotatably engages with it. A driving part 32 is provided on the swing rod 3. This driving part 32 is connected to the second cover 22 and is used to drive the first cover 21, the second cover 22, and the third cover 23 to move via the second cover 22. This structure allows the cover to be quickly and easily closed, resulting in a compact overall structure. Specifically, the driving part is cylindrical. Furthermore, the third cover 23 has a sliding groove 231, within which the driving part 32 is located. The sliding groove 231 is arc-shaped. The driving part 32 has a first state of sliding within the sliding groove 231 and a second state of driving the third cover 23 and the first cover 21 via the second cover 22. The sliding groove design allows for the movement of the drive unit, preventing increased gaps between the second and third covers, and between the third and first covers, during the rotation of the swing arm, which could damage the product. The swing arm movement is reliable and can reliably drive the cover movement.
