Adaptive plug-in structure for discharge plug of electric motorcycle

Abstract

A adaptive plug-in structure for a discharge plug of an electric motorcycle. A connecting base in which plug pieces are inserted is movably arranged in an accommodating cavity at the bottom of a battery. The plug pieces are in a movable state at the bottom of the battery and is capable of moving along a direction perpendicular to the plug pieces. During the process of placing the battery into a battery holder, if there is a positional deviation between the discharge plug and a plug-in base, and the plug pieces are not completely aligned with socket elastic members, after the plug pieces are in contact with openings of the socket elastic members, as the plug pieces move downwards, the plug pieces and the connecting base connected thereto will move under the guidance of inclined surfaces of the openings of the socket elastic members until the plug pieces are fully aligned with the socket elastic members. That is, the connecting base movably connected at the bottom of the battery can adaptively move when the plug pieces are subjected to force, so as to overcome positional deviations when the battery is placed. This arrangement can effectively solve the problem of plugging difficulty caused by positional deviations between the discharge plug of the electric motorcycle battery and the plug-in base inside the battery holder, helping to reduce the difficulty of battery insertion and removal and improving user experience and product competitiveness.

Description

Self-adaptive plug structure of discharging plug of electric motorcycle TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric vehicles, and particularly relates to a self-adaptive plug structure of a discharging plug of an electric motorcycle. BACKGROUND

[0002] To promote energy saving and emission reduction and environmental protection, major cities have begun to advocate the use of electric vehicles, such as electric buses, electric cars and electric motorcycles. Electric motorcycles are one of the most convenient electric vehicles for personal travel. To facilitate the taking and placing of the battery of an electric motorcycle, the electric motorcycle is usually provided with an upwardly open battery seat barrel at a position corresponding to the fuel tank of a fuel motorcycle or below a seat. The battery is placed vertically in the battery seat barrel and is fixed by a cover plate or a cushion. The output interface of the battery is usually arranged on the top of the battery together with the charging port. When the battery is taken or placed, the plug is manually unplugged or plugged so as to disconnect or connect the battery and the electric motorcycle. The use is relatively inconvenient.

[0003] To reduce the difficulty of taking and placing the battery and improve the use experience, a novel series-parallel battery terminal seat barrel is disclosed in Chinese patent CN213184497U, and a quick engagement mechanism of an electric bicycle and an electric motorcycle is disclosed in Chinese patent CN203063645U. At present, a plug base is usually arranged at the bottom of the battery seat barrel, a socket spring is arranged on the plug base, a plug is arranged at the bottom of the battery corresponding to the socket spring, a discharging plug is formed corresponding to the plug base, and the output interface on the top of the original battery is replaced. When the battery is placed in the battery seat barrel, the inside wall of the battery seat barrel limits the position of the battery to play a plug positioning role. The plug of the discharging plug is directly opposite the socket spring on the plug base and is plugged and matched, the battery and the electric motorcycle are connected, the battery is taken out, the plug is separated from the socket spring, the electrical connection is disconnected, the manual operation of unplugging the plug is omitted, and the taking and placing of the battery is more convenient. However, due to the manufacturing and assembly precision and the use wear, the position of the discharging plug and the plug base deviates, the plug and the socket spring cannot be completely opposite, especially in the direction perpendicular to the plug, the plug cannot be plugged and matched with the socket spring when the battery is placed, even if the plug is successfully plugged and matched, the plug and the socket spring have a relative movement trend in the direction perpendicular to the plug. Not only does the plug and the socket spring deform and be damaged, but also the friction between the plug and the socket spring is increased, the battery is taken out, and the plug and the socket spring are separated, which is relatively laborious. Therefore, further optimization is needed.
