Description

Technical Field

[0001] This utility model relates to an electric vehicle, and more particularly to a front guard device disposed between the handlebars and the front bulkhead. Background Technology

[0002] The main structure of an electric bicycle includes a steel frame, which serves as the structural foundation. A stem tube is welded and fixed to the front of the frame. The pivot of the front fork is rotatably inserted into the stem tube, with the handlebars connected to the upper end of the pivot. The front wheel is rotatably mounted on the lower end of the front fork. The front of the electric bicycle has a front fairing, with a decorative panel extending diagonally upwards from the front side, extending to the handlebars. A backplate is located behind the handlebars, extending upwards from the pedals to the handlebars. Together, the decorative panel and backplate form a front guard between the handlebars and the front fairing, covering the area between the lower part of the handlebars and the front fairing. The decorative panel and backplate are typically made of plastic materials such as PP, ABS, ASA, POM, PA, PC, and PE. This type of front guard device for electric bicycles suffers from poor impact protection and a short lifespan.

[0003] Chinese patent document (authorization announcement number: CN 204452631U) discloses an electric vehicle front enclosure and an electric vehicle, relating to the field of electric vehicle technology. The electric vehicle front enclosure includes a toolbox base plate and a front enclosure plate connected to the toolbox base plate.

An outer edge covering portion is provided along the circumferential direction of the outer edge of the front enclosure plate, and the outer edge covering portion covers the outer periphery of the toolbox base plate and is connected to the toolbox base plate. This improves the assembly stability of the electric vehicle front enclosure.

[0004] This type of front panel is similar to the front panel structure on ordinary electric vehicles. Its front is also a piece of plastic decorative panel. In the process of application, it is also prone to relatively low overall strength, and the anti-collision effect and service life cannot reach a satisfactory level. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a front cover device for electric vehicles, which effectively covers the part between the handlebars and the front bulkhead of the electric vehicle, making the overall structure of the electric vehicle novel.

[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a front guard device for electric vehicles, disposed at the front end of an electric vehicle, for covering the connection between the handlebars and the front bulkhead of the electric vehicle. The device is characterized by comprising a cylindrical upper guard sleeve fitted around the outer periphery of the connection. A connecting frame fixed to the handlebar tube of the electric vehicle is provided at the lower end of the connection. A connecting seat for supporting the lower end of the upper guard sleeve is provided on the connecting frame. A sealing member for closure is provided at the upper end of the upper guard sleeve, fitted around the outer periphery of the connection.

[0007] This front guard device forms a closed structure around the connecting part, providing both decorative effect and protection for the wiring connector at the bottom of the electric vehicle handlebars. The shape of the closure matches the cross-sectional shape of the upper guard, effectively sealing the upper end of the upper guard.

[0008] Furthermore, the connecting seat is ring-shaped, and its shape is adapted to the cross-sectional shape of the upper casing. This type of connecting seat is well-suited to the support requirements of the cylindrical upper casing, providing stable support for it.

[0009] Furthermore, the lateral width of the connecting seat is greater than the thickness of the upper casing wall. The lower end of the upper casing sidewall can be embedded in the connecting seat, providing good support stability for the upper casing.

[0010] Furthermore, the connecting frame extends towards the front end of the electric vehicle, and a fixing block is fixed to the connecting frame. The fixing block is arc-shaped, and the connecting seat is fixed to the fixing block. The fixing block is generally made of iron, and the connection transition is achieved through the fixing block, allowing the connecting frame to provide good support for the connecting seat.

[0011] Furthermore, the fixing block rests on the lower surface of the connecting seat, and an arc-shaped pad is fixedly installed on the connecting seat at a position corresponding to the fixing block. The pad abuts against the lower end of the upper protective sleeve, and an outer trim panel is adaptedly connected to the outside of the pad. The pad is generally made of rubber or plastic and has a certain degree of elasticity. The pad can fill the gap formed between the lower front end of the inclined upper protective sleeve and the connecting seat, thereby sealing the lower end of the upper protective sleeve and allowing the upper protective sleeve to adapt well to the setting direction of the electric vehicle front fork pivot.

[0012] Furthermore, a ring-shaped pressure ring is connected to the upper end of the upper casing, and the sealing element is connected to the pressure ring. The pressure ring is provided with a mounting bracket extending outward. The pressure ring effectively seals the upper end of the upper casing, provides a fixed mounting position for the sealing element, and also provides mounting support for the windshield of the electric vehicle.

[0013] Furthermore, the upper casing is made of aluminum alloy, and several connecting strips are integrally formed protruding from the inner circumference of the upper casing. The connecting strips extend along the length of the upper casing, and each connecting strip has a connecting hole that opens towards the end of the connecting strip. The presence of these connecting strips not only improves the strength of the upper casing but also facilitates the connection between the upper casing and other components via screws.

[0014] Furthermore, the upper casing has a split structure, comprising two arc-shaped units that are interlocked together. This facilitates the extrusion molding of the upper casing, makes it easy to install and disassemble, and is well-suited for maintenance of the connectors and structure at the connection points.

[0015] Furthermore, each of the two individual units has an integrally formed connecting groove and a connecting protrusion at the interlocking surface. Both the connecting groove and the connecting protrusion extend along the length of the upper protective sleeve. The cross-section of the connecting groove is U-shaped, and the cross-section of the connecting protrusion is U-shaped. The connecting protrusion is inserted into the connecting groove. This mating connection structure allows for assembly and disassembly via a direct insertion method, making operation very simple and ensuring a strong connection between the two units. Moreover, this mating connection structure is also well-suited for units made of aluminum alloy, as their straightness is excellent, facilitating easy installation and disassembly between the two units.

[0016] Compared with existing technologies, this utility model has the following advantages: A front cover device is provided at the connection point at the front of the electric vehicle, forming a cylindrical structure at the corresponding position. This is different from the design of ordinary electric vehicles, resulting in a novel overall structure. The front cover device at the connection point ensures good sealing, allowing for a new design for the front of the electric vehicle. A connecting seat supported on the handlebars provides support for the front cover device and also provides connection support for the front of the electric vehicle, simplifying the connection structure at the front of the electric vehicle and facilitating the installation of electric vehicle components.
