[0025] In this embodiment, a connecting post 33 is provided on the fixed connector 3, and the end of the main support bar 2 is hinged to the connecting post 33. The fixed connector 3 is integrally formed or assembled with the connecting post 33 as a hinge fulcrum.

[0026] In this embodiment, a connector 21 is fixedly provided at the end of the main support bar 2. A hinge interface 22 is provided on the connector 21. The hinge interface 22 is hinged to the connecting post 33. The connector 21 is provided with a fixing hole. The end of the main support bar 2 is inserted into the fixing hole, which makes the overall assembly convenient. Alternatively, the connector 21 is formed by bending the end of the main support bar 2 to form a ring structure of the hinge interface 22, which is integrally molded and the structure is more robust. During injection molding, the connector 21 is connected to the main support bar 2 as a whole.

[0027] In this embodiment, an anti-detachment cap 34 is connected to the outer side of the connecting post 33. When the connecting post 33 has an external thread and the anti-detachment cap 34 has an internal thread, the two are connected by threads. The anti-detachment cap 34 is a nut, including a hexagonal nut, an end cap nut, and a lock nut. When the connecting post 33 has an internal thread and the anti-detachment cap 34 has a connecting stud, the two are connected by threads. When the connecting post 33 has a connecting hole and the anti-detachment cap 34 has a connecting rod, the two are connected by insertion. The anti-detachment cap 34 is assembled after the hinge is completed, which can limit the axial displacement of the hinge interface 22 of the connector 21 along the connecting post 33.

[0028] In the embodiment, the fixed connector 3 is provided with a reinforcing protrusion 35 at the connecting post 33. The reinforcing protrusion 35 increases the contact area between the connecting post 33 and the fixed connector 3, avoiding root breakage and deformation of the connecting post 33 due to long-term stress concentration, and greatly improving the structural strength and durability of the hinge part.

[0029] In this embodiment, the bottom of the cover 1 is provided with a first seam, and two main support bars 2 are respectively inserted into the first seam with their ends protruding from the first seam. This prevents the support bars from shifting or twisting during use and ensures that the support bars provide uniform support for the cover. The seam wraps around the support bars, reducing direct friction between the support bars and the waterproof fabric, preventing fabric wear and tear, and extending the service life of the cover. The design of the support bars being inserted into the seam does not require additional welding or bonding for fixation, simplifying the assembly process and reducing production difficulty and cost.

[0030] In this embodiment, at least one second seam is provided on the inner surface of the cover 1, and the auxiliary support strip 4 is inserted inside the second seam to prevent the support strip from shifting or twisting during use and to ensure that the support strip provides uniform support for the cover.

[0031] In this embodiment, the seat cover also includes an openable auxiliary fixing component 5. The auxiliary fixing component 5 includes a fixing component 51 and a separating component 52. The fixing component 51 is fixed to the electric bicycle seat or body with adhesive, and the separating component 52 is disposed on the cover 1. The fixing component 51 of the auxiliary fixing component 5 is fixed to the corresponding position of the electric bicycle seat or body with adhesive, and the separating component 52 is pre-positioned in the corresponding position of the cover 1. When the main support bar 2 supports the cover 1 to form a protective cavity, the opening and closing of the fixing component 51 and the separating component 52 achieves secondary fixation between the cover 1 and the seat / body. When storing, the fixing component 51 and the separating component 52 can be separated, and the cover can be folded synchronously with the support bar. The secondary fixing design of the cover body 1 and auxiliary fixing parts 5 effectively improves the wind resistance of the cover body, preventing the cover body from shifting or falling off under bumpy riding or strong wind weather. The opening and closing operation of the fixing parts and the separation parts is simple and does not affect the quick unfolding and storage of the cover body. The seat cover also includes a magnetic part, which is attached to the rear of the electric bicycle with adhesive. The main support bar 2 is made of ferromagnetic material and can be attracted with the magnetic part. Alternatively, the auxiliary fixing parts 5 can be relatively fixed with Velcro or snap fasteners. The auxiliary fixing parts 5 can be in the form of magnetic, Velcro, snap fasteners, etc., to adapt to different usage scenarios. The operation is simple and provides secondary fixing of the cover body, with good wind resistance and anti-shifting effect.

[0032] In this embodiment, the outer surface of the cover 1 is provided with a reflective coating.

[0033] In this embodiment, there are two auxiliary support bars 4, and when the two auxiliary support bars 4 are unfolded, they form a 60° angle with the bottom of the cover 1.

[0034] In this embodiment, the main support bar 2 is made of hard steel wire or aluminum alloy wire, and the auxiliary support bar 4 is made of hard steel wire or aluminum alloy wire.

[0035] I. Working Principle: This electric bicycle seat cover uses a waterproof fabric cover as the main protective element, a U-shaped support bar as the frame, and a hinged fixing connector as the mounting base. Through a coordinated design of "support-protection-folding," it achieves waterproof, dustproof, and sun protection for the seat, while also ensuring convenient storage and portability. The specific principle is as follows: The fixed support principle involves fixing the fixed connector to the edge of the electric bicycle seat or body through its own adhesive layer (or additional glue or double-sided tape). The integrally molded or assembled connecting column serves as the hinge fulcrum of the main support bar. The connector at the end of the support bar is hinged to the connecting column through the hinge interface. The anti-detachment cap restricts the axial displacement of the connector, and the reinforcing protrusion increases the contact area between the connecting column and the connector to avoid breakage under stress and ensure the structural stability of the support frame. The support structure features two main support bars positioned opposite each other along the bottom edge of the cover, with their ends hinged to a fixed connector. At least one auxiliary support bar is threaded through the seam on the inner surface of the cover. In the unfolded state, the first and auxiliary support bars work together to support the waterproof fabric cover, forming a stable protective cavity that provides full coverage of the bicycle seat. The waterproof fabric blocks rain, dust, and sunlight, while the reflective coating on the outer surface of the cover enhances visibility while riding. The secondary fixation and anti-displacement principle involves the cover being equipped with magnetic, Velcro, or snap fasteners that can be opened and closed. The fasteners are attached to the seat / body of the bicycle, while the detachable parts are set on the cover. When the cover is opened, the auxiliary fasteners snap together to achieve secondary fixation, which effectively improves wind resistance and prevents the cover from shifting or falling off during bumpy rides or in strong winds. The folding and storage principle is based on the hinge structure of the support bar and the fixed connector. Under the action of external force, the main support bar can be folded to one side, which drives the auxiliary support bar and the cover to fold synchronously, greatly reducing the volume and making it easy to store and carry. Based on the principle of wear-resistant and durable structure, the main support strip is inserted into the first seam at the bottom of the cover, and the auxiliary support strip is inserted into the second seam on the inner surface. The seam wraps around the support strip, reducing direct friction between the support strip and the fabric and preventing the fabric from being worn and torn. The support strip is made of hard steel wire or aluminum alloy wire, which takes into account both strength and toughness and extends the overall service life. II. Usage Method (I) Preliminary Preparations Clean the edges of the electric bicycle seat or the mounting area on the frame to ensure the surface is dry and free of dust and oil, which will improve the adhesion of the adhesive. Check the integrity of the seat cover accessories, including the cover body, two main support bars, at least one auxiliary support bar, two fixing connectors, and anti-slip caps (if any). (ii) Installing and fixing the fasteners Peel off the protective film from the mating surface of the fastener to expose the adhesive layer; Align the connector with the edge of the seat or the designated installation position on the vehicle body, press evenly for 10-15 seconds to ensure that the adhesive layer is completely adhered to the installation surface, and complete the base fixing; If using connectors without adhesive, apply adhesive or double-sided tape before pressing to secure them. (iii) Unfold and secure the cover Hold the main support bar and pull it outward to make it rotate and unfold around the connecting column, which will drive the auxiliary support bar to open the cover at the same time until the cover forms a full protective cavity that completely covers the seat. Attach the detachable parts on the cover to the fixing parts of the seat / body (magnetic adsorption, Velcro, or snap fasteners) to complete the secondary fixation and improve wind resistance; (iv) Folding and storage First, loosen the secondary fasteners (such as pulling off the Velcro or separating the magnetic fasteners); Gently push the main support bar to one side to make it rotate and retract around the connecting column, causing the auxiliary support bar to fold synchronously with the cover until the volume is minimized. The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
