Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, and in particular to an external battery pack for electric scooters. Background Technology

[0002] Currently available electric scooters have their batteries installed under the footboard, resulting in a complex installation structure that is difficult to disassemble and replace. Furthermore, during operation, the battery is susceptible to short circuits due to vibration or damage from road surfaces due to its low-lying connection. An existing patent application (CN202123003695.3) describes an external battery mounting structure for electric scooters, comprising a handlebar assembly and a battery assembly. The handlebar assembly is connected to a detachable battery assembly… This structure is simple, easy to install and lock, and highly safe. It locks the connection between the battery assembly and the handlebar by pressing down, preventing short circuits or power outages caused by vertical movement of the battery assembly. However, this battery pack can only be fixed to a specific scooter handlebar and cannot adapt to handlebars of different sizes and shapes. It also does not reduce the vibration transmitted from the scooter to the battery pack. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to adapt to different sizes and shapes of handlebars on different scooters and the inability to reduce vibrations transmitted from the scooter to the battery pack. Therefore, this invention proposes an external battery pack for electric scooters.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an external battery pack for an electric scooter, including an electric scooter handlebar and a battery pack body. A pair of buffer connecting strips are glued to the right end of the battery pack body. An arc-shaped groove is formed at the right end of the pair of buffer connecting strips, and an arc-shaped plate is glued in the arc-shaped groove. A strap covering the outer wall of the electric scooter handlebar is glued to the inner arc surface of the pair of arc-shaped plates. Connecting strips are fixed at both the upper and lower ends of the front buffer connecting strips, and a thin shaft is fixedly connected to the right end of the pair of connecting strips. The front end of the strap, after passing around the electric scooter handlebar, passes around the thin shaft again and folds back to cover the outer wall of the electric scooter handlebar. A Velcro female and a Velcro female are glued to the outer wall of the strap, and the Velcro female is glued to the inner side of the strap that passes around the thin shaft and folds back to cover the outer wall of the electric scooter handlebar.

[0006] Preferably, a sleeve located between a pair of connecting bars is fitted onto the outer wall of the thin shaft.

[0007] Preferably, the strap includes a base fabric layer, and an anti-slip rubber layer is laminated and fixed on the inner wall of the base fabric layer attached to the handlebar of the electric scooter, and a hard protective rubber layer is laminated and fixed on the outer wall of the base fabric layer.

[0008] Preferably, the base fabric layer is woven from metal wires.

[0009] Preferably, the inner wall of the anti-slip rubber layer is provided with a plurality of circular grooves, and a suction cup and a soft silicone filling ring are fixed in the circular grooves, with the soft silicone filling ring filling between the suction cup and the anti-slip rubber layer.

[0010] Preferably, the inner wall of the anti-slip rubber layer is provided with anti-slip texture.

[0011] Preferably, the inner wall of the anti-slip rubber layer is provided with a plurality of grooves, and anti-slip protrusions are bonded to the grooves, and the outer arc surface of the anti-slip protrusions is coated with an anti-slip coating.

[0012] The present invention provides an external battery pack for electric scooters, which has the following advantages: the battery pack can be fixed to the handlebars of the electric scooter via straps, eliminating the need for any connecting components to be fixed to the handlebars. The freely shape-adjustable straps can adapt to handlebars of different diameters and sizes, allowing the battery pack to be used on different electric scooters and attached to other cylindrical parts of the electric scooter. This broadens its applicability and makes it more flexible to use. Furthermore, the buffer strips isolate and buffer vibrations transmitted from the handlebars, reducing the impact on the battery pack. Attached Figure Description
