Height-adjustable automatic supporting foot stool for electric vehicle

Abstract

The invention discloses a height-adjustable automatic supporting foot stool for an electric vehicle. The left end and the right end of the straight tooth bevel gear transmission mechanism are both coaxially connected with an electromagnetic lock transmission mechanism, wherein the electromagnetic lock transmission mechanism is coaxially sleeved with a first gear, and the first gear is connected with a second gear through a toothed belt; a central gear connecting sleeve of the second gear is coaxially and fixedly connected with a third gear; a horizontal rack meshed with the third gear is arranged on the upper section of the foot stool; the electromagnetic lock transmission mechanism is composed of a battery, an electric wire, a hollow transmission shaft, a first rotating shaft sleeve, two T-shaped electromagnets and a second rotating shaft sleeve which have the same central shaft. The straight tooth bevel gear transmission mechanism is driven by the motor to transmit power to the gear rack mechanism, and the foot stool is driven to ascend or descend. When the electromagnets on the left side and the right side are electrified simultaneously, the foot stools on the two sides can ascend or descend simultaneously; if the electromagnet on one side is powered off, the power transmission on the side is interrupted; therefore, independent control over ascending or descending of the left foot stool or the right foot stool can be achieved according to different parking road conditions.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a support tripod for stably supporting the electric vehicle when the electric vehicle is parked. Background technique [0002] Traditional electric vehicles have two tripods: the main tripod and the partial tripod. The off-set tripod is easy to use, but has poor stability and is prone to tipping over when loading. For women and people with little strength, the main tripod needs to be raised to lower the main tripod, which will cause parking burdens. In special road conditions, such as road sections with high slopes, electric vehicles that have been parked If it encounters external force, it is easy to fall and cause damage. [0003] The current docking device for electric vehicles, such as a length-adjustable electric vehicle side strut disclosed in the Chinese patent application No. The adjustable pole can be used to dock on ground with different heights, but its function is ...

Problems solved by technology

The off-set tripod is easy to use, but the stability is poor, and it is prone to tipping when loading

For women and people with little strength, the main tripod needs to be raised to lower the main tripod, which will cause parking burdens. In special road conditions, such as road sections with high slopes, electric vehicles that have been parked If encountering external force, it is easy to fall and cause damage

[0003] The current docking device for electric vehicles, such as a length-adjustable electric vehicle side strut disclosed in the Chinese patent application No. The pole with adjustable function can handle the ground with different heights, but its function is relatively single, and the pole is only installed on one side of the electric vehicle, which cannot guarantee the stability of docking

Chinese patent application number 201721752266.7 discloses a self-adjustable width electric vehicle undercarriage. During the falling process of the electric vehicle undercarriage, the support wheels touch the ground, and the support wheels continue to move forward slowly for a period of time. Only when the distance between them gradually increases can the support width of the landing gear become larger. If parking in a narrow space, this function will be greatly restricted, and the connection between the device and the electric vehicle is not adjustable. The scope of application is greatly reduced
