Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle battery replacement, in particular to a hanging basket structure with rollers. Background Art

[0002] Existing electric vehicles can be divided into hybrid, extended-range and pure electric types. Among them, pure electric electric vehicles will bring certain range anxiety due to battery limitations. Even though major car companies have been developing faster fast charging technology and battery life expansion technology, it is still difficult to meet users' demanding requirements for fast charging. They urgently hope that electric vehicles can achieve the same fast power replenishment speed as refueling gasoline vehicles.

[0003] Therefore, battery swapping technology came into being. Compared with the slow battery charging process, directly replacing the battery obviously has a faster "charging" speed. Among the existing electric vehicle battery swapping technologies, some electric vehicles use the "front-end battery swapping" method, that is, the battery at the bottom of the vehicle is pulled out from the battery compartment that contains the battery from the front of the vehicle, and then the new battery is filled into the battery compartment from the front of the vehicle to achieve "battery swapping".

[0004] However, the battery outlet of the existing front-end battery-swap electric vehicles is basically flush with the front of the vehicle or slightly behind it. If the vehicle encounters a head-on or front-side collision during driving, it is very easy to cause the door of the battery compartment at the bottom of the vehicle to deform, making it impossible to remove the battery, and there is a high possibility of directly damaging the internal battery. If the battery is damaged in the battery compartment and catches fire, it will cause greater economic losses and even casualties. Utility Model Content

[0027] Embodiment 1

[0028] See also Figure 1-3 As shown, the hanging basket structure with rollers of this embodiment includes two supporting plates 1 installed on the bottom of the vehicle and arranged opposite to each other;

[0029] Two support plates 1 are located between the front of the vehicle and the battery compartment at the bottom of the vehicle;

[0030] The two support plates 1 are arranged in parallel along the moving direction of the battery 5 in and out of the battery compartment;

[0031] A plurality of horizontal rollers 2 are arranged on opposite surfaces of the two support plates 2. The horizontal rollers 2 on the two support plates 1 are located at the same height. The plurality of horizontal rollers 2 are arranged in a straight line on the support plates 1 along the moving direction of the battery 5 in and out of the battery compartment; the horizontal rollers 2 are used to bear weight and guide the battery 5 when it enters and exits the compartment door of the battery compartment;

[0032] Vertical rollers 3 are provided at the front and rear ends of the support plate 1 , and the vertical rollers 3 are used to guide the batteries 5 when they enter and exit the battery compartment door.

[0033] The length of the hanging basket structure is about 20 cm. The battery compartment at the bottom of the vehicle is moved as a whole more than 20 cm to the rear of the vehicle. The hanging basket structure is set in the empty space at the front end. The top of the hanging basket structure is fixed to the bottom of the vehicle. There is a certain distance between the battery compartment and the hanging basket structure to facilitate the opening and closing of the battery compartment door.

[0034] Specifically, the horizontal roller 2 can support the battery 5 when taking the battery 5 out of the battery compartment or putting the battery 5 into the battery compartment. The rolling action of the horizontal roller 2 facilitates the movement of the battery 5. The vertical roller 3 can guide the battery 5 when the battery 5 approaches the two support plates 1 to ensure that the battery 5 moves in the correct direction and prevent the battery 5 from shaking.

[0035] By arranging this structure in front of the battery compartment, the impact of the vehicle on the battery compartment due to frontal or front side collision can be effectively cushioned, and deformation of the battery compartment door can be avoided; at the same time, if there are abnormal objects on the road surface, and the vehicle bottoms out due to insufficient bottom height, the risk of direct frontal collision of the battery compartment by objects on the road surface is avoided.

[0036] It should be noted that the two support plates 1 are of equal length, and a gap is left between the end of the support plate 1 close to the battery compartment and the compartment door of the battery compartment, and the size of the gap needs to meet the normal opening and closing of the compartment door of the battery compartment.

[0037] It should be noted that the distance between the two vertical rollers 3 on the same end of the two support plates 1 is adapted to the width of the battery 5 .

[0038] It should be noted that the shape of the horizontal roller 2 is similar to the grooves on the two side walls of the battery 5 .

[0039] When it is necessary to take out the battery 5 in the battery compartment, the method of using the utility model is as follows:

[0040] The door of the battery compartment is opened, and the driving mechanism in the battery compartment transports the front end of the battery 5 out of the battery compartment. The vertical roller 3 guides the moving direction of the battery 5. The grooves on the two side walls of the battery 5 are respectively stuck on the horizontal rollers 2 on both sides (such as the attached Figure 2or a plurality of horizontal rollers 2 on both sides respectively drag the bottom of the battery 5 (as shown in the attached Figure 3 As shown); the identification system of the battery swapping vehicle at the battery swapping site identifies the battery 5, and then the battery swapping vehicle drags the bottom of the battery 5 to remove the battery 5 from the vehicle.

[0041] When the battery 5 needs to be placed in the battery compartment, the method of using the utility model is as follows:

[0042] The battery swapping trolley tows the battery 5, and identifies the positions of the two vertical rollers 3 in front through the identification system of the battery swapping trolley, and clamps the grooves on the two side walls of the battery 5 onto the several horizontal rollers 2 on both sides according to the positions of the two vertical rollers 3 (as shown in the attached figure). Figure 2 or place the battery 5 on the horizontal rollers 2 on both sides, so that the horizontal rollers 2 on both sides respectively drag the bottom of the battery 5 (as shown in the attached Figure 3 As shown); the battery-changing trolley pushes the battery 5 forward until all the batteries 5 enter the interior of the battery compartment; the driving mechanism in the battery compartment transports the battery 5 to the interior of the battery compartment and closes the door of the battery compartment.

[0043] Embodiment 2

[0044] See also Figure 1 As shown, the hanging basket structure with rollers in this embodiment is different from that in the first embodiment in that a connecting plate 4 is provided between the two support plates 1, and the connecting plate 4 is located on the top of the two support plates 1. The addition of the connecting plate 4 can enhance the structural strength between the two support plates 1 and prevent deformation.

[0045] The utility model can protect the battery compartment and the battery 5 inside it, and assist the battery 5 to enter and exit the battery compartment. The roller of the hanging basket structure does not need to be provided with a driving device, and the battery 5 can be dragged to move in the hanging basket structure by using the battery driving mechanism of the battery compartment and the battery pushing device of the battery replacement trolley, without consuming any electric energy.

[0046] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
