Description

Battery Transporter for Micro Electric Vehicles

technical field

The utility model belongs to the technical field of automobile accessories, and in particular relates to a battery transportation device for a micro electric automobile.

Background technique

An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Compared with traditional cars, electric vehicles have the advantage of less impact on the environment, therefore, electric vehicles have excellent application prospects.

One of the difficulties in the promotion of existing electric vehicles is: because the rechargeable battery of the electric vehicle is relatively large in size and difficult to move, it is necessary to charge the rechargeable battery inside the electric vehicle by means of a professional charging pile. The biggest disadvantage of this method is: At present, the number of public charging piles in my country's cities is limited, and the installation cost of private charging piles is relatively high. Therefore, it is very inconvenient for car owners to charge electric vehicles, which limits the widespread promotion of electric vehicles.

The support frame 3 is set under the main frame 2, and the support frame 3 is sleeved inside the frame of the main frame 2, and the main frame 2 can slide up and down along the support frame 3 and be fixed; the advantage of this design structure is: when the battery is transported When the device is stored in the vehicle body, the height of the entire battery transport device can be adjusted by sliding the main frame;

The middle part of the support frame 3 can be folded to set a support platform 4, which is used to place the battery. In order to achieve the purpose of stably fixing the battery, the following two structural forms can be adopted: (1) There are also two structures on the left and right sides of the support frame 3 Tension belt; when the battery is placed on the support platform, the battery is fastened by the tension belt; (2) the upper surface of the support platform 4 has a groove adapted to the shape of the battery; the groove is used to place and fix the battery.

Finally, the bottom of the support frame 3 is provided with casters. Through the casters, the battery transport device can be easily moved. Usually, in the way of transporting the battery to charge at home, when encountering stairs, in order to make the battery transport device easily pass through the stairs, in the utility model, a caster with a three-wheel design structure is adopted, that is, the caster includes: through the crankshaft The left wheel system 5 and the right wheel system 6 are arranged on the left and right sides of the bottom of the support frame 3; the left wheel system 5 and the right wheel system 6 have the same structure, and both include: The wheel 5.2 and the upper wheel 5.1 are arranged in an equilateral triangle. When passing the stairs, the front wheels and the upper wheels are stuck on the stairs, and when the transport device is pulled up, the positions of the three wheels are exchanged, so that the transport device can be easily moved to the upper step.

In addition, in order to increase the functionality of the battery transport device, at least one hook 7 may also be provided on the main frame 2 ; the hook 7 is foldably connected to the main frame 2 . Through the hook, when the transport device is not transporting the battery, the transport device can be used to go shopping, for example, a shopping bag can be hung on the hook, thereby expanding the function of the transport device to meet different needs of people.
