Description
Technical Field
The utility model belongs to the technical field of electric vehicles, and particularly relates to a detachable electric bicycle frame and an electric vehicle.
Background
The existing light electric bicycle or electric power-assisted vehicle usually adopts lithium battery to provide power, and does not have a battery compartment like a conventional pedal type electric bicycle to protect the battery due to simple structure. Some light electric bicycles or electric power-assisted vehicles also adopt the battery compartment to be directly arranged on the frame, although the batteries are convenient to detach, the structure of the light electric bicycles or the electric power-assisted vehicles is not compact enough, and the appearance is also influenced. The common electric bicycle with compact structure is that the battery compartment is made into a tubular shape and is fixedly connected to the frame as a part of the frame. However, the above-mentioned battery tube structure is integrated with the frame, which brings great inconvenience when the lithium battery needs to be disassembled for charging or damaged for replacement.
Disclosure of Invention
The utility model aims to provide a detachable electric bicycle frame and an electric bicycle, which have compact structure and are convenient for disassembling a battery tube, aiming at overcoming the defects of the prior art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a can dismantle electric bicycle frame, includes the frame body, its characterized in that: at least one frame pipe fitting on the frame body is provided with a detachable battery tube, and the battery tube is connected with the frame pipe fitting through a connector. The battery tube is detachably arranged, so that the battery can be conveniently detached for charging and replacing. The battery tube can be connected with the frame tube by adopting a common bolt type connector or a male-female matched connector, and is suitable for quick disassembly of the battery tube.
It is further characterized in that: the connector is locked and fixed through a locking device. In order to ensure the reliable connection between the battery tube and the frame tube and improve the connection strength, the connector is reinforced and fixed outside the connector through a locking device.
Preferably: the connector comprises two connecting pieces with semi-circular bosses, and the connecting pieces are respectively and fixedly arranged on the frame pipe fitting and the battery pipe; the quasi-semi-circular bosses of the two connecting pieces are matched to form a quasi-circular boss when connected. The connecting piece is respectively fixedly connected to the frame pipe fitting and the battery tube through screws, when the connecting piece is connected, the two mutually staggered semi-circular bosses are spliced into a circular shape, and then the circular shape is locked and fixed through the locking device. The connector of this kind of structure need not to change the distance of the frame pipe fitting at both ends when battery pipe installation and dismantlement, and the boss cooperation is inseparable simultaneously, guarantees the intensity of connecting.
Preferably: the locking device is in a hoop shape, the inner wall of the locking device is provided with a clamping groove, and the quasi-circular boss of the connecting piece is embedded into the clamping groove. The boss after will piecing together imbeds the draw-in groove for frame pipe fitting and battery union coupling are inseparabler, also by a wide margin improved the intensity of junction, make battery pipe and frame form a whole.
Preferably: the locking device comprises two semicircular clamping grooves, one sides of the two clamping grooves are connected through a pivot, and the other sides of the two clamping grooves are fixed through screws. The structure is convenient for the quick disassembly of the battery tube.
Preferably: the battery tube is connected to the lower tube of the frame body.
An electric vehicle, characterized in that: adopt foretell detachable electric bicycle frame. The detachable electric bicycle frame has compact structure and attractive appearance, and can realize quick detachment and installation of the battery.
The utility model adopts the connecting piece to connect the battery tube to the frame tube, ensures the frame strength, makes the frame compact and beautiful, and is convenient for quick disassembly and assembly of the battery tube.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a schematic view of a battery tube connection structure.
Fig. 3 is a schematic view of the structure of the connector.
Fig. 4 is a schematic structural view of the locking device.
Detailed Description
As shown in figure 1, a detachable electric bicycle frame comprises a frame body 1, a detachable battery tube 2 is arranged on an upper tube 4 and a lower tube 4 of the frame body 1, and the battery tube 2 is connected with the lower tube 4 through connectors of quick-release structures such as plug pin connectors or male-female matched connectors, so that the battery tube 2 can be detached and installed quickly.
As shown in fig. 1 and 2, the exterior of the connector is locked and fixed by a locking device 3, so that the reliable connection between the battery tube 2 and the lower tube 4 is ensured, and the connection strength is improved.
In a preferred form, as shown in fig. 2 and 3, the connector includes two connectors 5 having semi-circular bosses 51, the connectors 5 are respectively fixed to the lower tube 4 and the battery tube 2 by screws; the semi-circular-like bosses 51 of the two connectors 5 are matched to form a circular-like boss when connected.
As shown in fig. 2 and 4, the locking device 3 is in a hoop shape and includes two semicircular slots, one side of each of the two slots is connected by a pivot, and the other side of each of the two slots is fixed by a screw. When in use, the quasi-circular boss of the connecting piece 5 is embedded into the clamping groove.
When the battery tube 2 is installed, the connecting pieces 5 are fixed on two sides of the lower tube 4 and two ends of the battery tube 2 through screws, the battery tube 2 is embedded into a gap on two sides of the lower tube 4, semi-circular bosses 51 of the two connecting pieces 5 are matched with each other to form a circular boss, and the battery tube 2 is positioned. Then through locking device 3 with the quasi-circular boss embedding draw-in groove of connecting piece 5 in, fixed locking device both sides through the screw, die two connecting pieces 5 lock for lower tube 4 and battery pipe 2 are connected more closely, have also improved the intensity of junction by a wide margin, make battery pipe 2 and frame body 1 form a whole.
An electric motor car adopts foretell electric bicycle frame of dismantling, compact structure, and the appearance is pleasing to the eye, also can realize dismantling fast, the installation of battery pipe 2 simultaneously.
