Description

Technical Field

[0001] The present invention relates to an electric vehicle parking management device, and in particular to a two-wheel electric vehicle charging parking space comprehensive management system and a use method thereof. Background Art

[0002] At present, when charging electric vehicles, they need to be parked in designated charging parking spaces before charging operations can be carried out. In order to meet the needs of vehicle charging management operations, electric vehicles that are in charging operations need to be parked in corresponding parking spaces. The currently used parking spaces are often simply divided into corresponding positions on the ground. Although this can meet the needs of vehicle parking, when the position of the vehicle parked in the parking space is fixed, the position of the vehicle parked in the parking space cannot be flexibly adjusted according to usage needs. It is very easy to cause some parking spaces to be unable to be fully utilized due to the inability to flexibly adjust the parking position, thereby causing a waste of charging spaces and making the current electric vehicle charging management and scheduling relatively difficult.

[0003] Therefore, in view of this situation, it is urgent to develop a new electric vehicle parking management device and method to meet the needs of actual use. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a new nursing bed structure. On the one hand, the present invention has a simple structure and is flexible to use, and can flexibly meet the needs of use and operation in a variety of different venues, while having good load-bearing and positioning capabilities for vehicles; on the other hand, in the process of vehicle load-bearing and positioning, the flexible adjustment of the parking space for the vehicle can be effectively realized without affecting the vehicle parking operation, thereby greatly improving the flexibility and convenience of vehicle parking management operations.

The bearing bracket is a groove-like frame structure with a "凵" - shaped cross-section. Its upper end surface is connected to the lower end surface of the bearing tray through at least two guiding slide rails and is parallel to the lower end surface of the bearing tray. The upper end surface of the bearing tray is at least several millimeters higher than the upper end surface of the bearing bracket. The bearing bracket and the bearing tray are coaxially distributed, and its length is 1 / 3 - 2 / 3 of the bearing tray. There are two pressure sensors in total.
