Description

TECHNICAL FIELD

[0001] The utility model relates to new energy heavy truck battery swap technical field especially relates to a compact charging and battery swap station. BACKGROUND

[0002] The popularization of battery swap heavy trucks greatly reduces carbon emissions, and the battery swap station that serves the heavy truck battery swap construction emerges as the times require. In order to meet the turnover demand of battery swap batteries and ensure that heavy trucks that need to be battery swapped can be timely battery swapped with full batteries, the battery swap stations commonly seen on the market usually store a large number of battery swap batteries, and the land occupation is large. However, sometimes the working conditions do not require too many batteries to meet the requirements, and on the other hand, the construction of a battery swap station with too large an area may be restricted by the site, so there is also a demand for small and micro battery swap stations on the market. In order to reduce the initial investment scale and reduce the land use area, micro version battery swap stations have appeared one after another. Most of the current micro version battery swap stations adopt a 3+1 scheme, that is, a container protection system is used, and three charging positions and one transfer position are built-in. For example, the charging and battery swap station disclosed in Chinese invention patent application No. CN117841918A published on April 9, 2024; or a 4+1 scheme as shown in Figure 1 The former 3+1 scheme has only three spare batteries that can be replaced and used, and the battery swap capacity is weak. The latter 4+1 scheme has one more spare battery, but there is an obstacle in the battery swap process. Specifically, in the 4+1 scheme, when the depleted battery 51 on the battery swap heavy truck 4 is moved to the transfer warehouse 21a, the full battery 52 on the front row of storage and charging positions 22a can be mobilized to supplement the battery swap heavy truck 4 to complete the battery swap.

[0003] However, after the battery swap is completed, the depleted battery 51 on the transfer warehouse 21a needs to be moved to the front row of storage and charging positions 22a for charging, as shown in Figure 2 When the next battery swap is performed, the full battery 62 on the rear row of storage and charging positions 22b cannot be moved out due to the battery obstruction on the transfer warehouse 21a and the front row of storage and charging positions 22a. In order to solve this problem, the full battery 52 on the rear row of storage and charging positions 22b needs to be "reversed" and moved to the front row of storage and charging positions 22a before the depleted battery 51 on the transfer warehouse 21a is moved, and then the depleted battery 51 is placed on the rear row of storage and charging positions 22b for charging. This reversing behavior increases the battery swap time and reduces the battery swap efficiency. On the other hand, it also increases the plugging and unplugging times of the charging connector, reduces the service life of the connector, and increases the after-sales replacement cost of the connector. At the same time, the reversing requires the battery to be moved by the battery swap equipment, which also consumes unnecessary energy.

[0004] Based on the above problems, it is urgent to provide a compact and small-sized battery replacement station with high battery replacement efficiency, to realize the non-complicated transfer between the charging positions and to maximize the battery replacement capacity of the battery replacement station in limited site area.

[0037] Please refer to Figures 3 to 9 As shown in the figure, the utility model provides a compact charging and battery swapping station 100 for providing charging and battery swapping services for new energy vehicles, the compact charging and battery swapping station 100 comprises a storage and charging space 2 for storing battery swapping batteries 5 and arranged on one side of a driving lane 40 and a hoisting layer 3 located above the storage and charging space 2, the hoisting layer 3 has a battery swapping top portion 31 extending beyond the storage and charging space 2 and located above the driving lane 40, the hoisting layer 3 is internally provided with a hoisting mechanism 30 reciprocally moving above the storage and charging space 2 and the driving lane 40, through the hoisting mechanism 30, the battery swapping batteries 5 in the storage and charging space 2 can be carried to above the battery swapping heavy truck 4 located on the driving lane 40, or the battery swapping batteries 5 on the battery swapping heavy truck 4 can be carried into the storage and charging space 2, so as to complete the battery swapping process of the compact charging and battery swapping station 100 in a battery swapping space 32. The battery swapping battery 5 is a box-shaped battery, which has a length in a direction perpendicular to the driving lane 40, a thickness in a direction parallel to the driving lane 40 and a height in a vertical direction. The storage and charging space 2 is internally provided with a first storage and charging platform 20 and externally provided with a protective shell 204 around the first storage and charging platform 20, the compact charging and battery swapping station 100 further comprises a plurality of charging machines 6 arranged outside the protective shell 204 of the storage and charging space 2 and an escalator 12 arranged on the same side as the charging machines 6, and the protective shell 204 is provided with an inspection door 201 at an upper end corresponding to the escalator 12.

[0038] The first storage and charging platform 20 is arranged in the storage and charging space 2, and a plurality of first storage and charging positions 22 for storing the battery swap battery 5 are arranged on the first storage and charging platform 20. The two first storage and charging positions 22 close to the driving lane 40 are provided with a battery swap channel 202 for the passage of the battery swap battery 5, and the hoisting mechanism 30 uses the battery swap channel 202 as a moving space to carry the battery swap battery 5. In order to complete the battery swap, the storage and charging space 2 is further provided with a transfer warehouse 21 for temporarily storing the battery swap battery 5. The overall height of the transfer warehouse 21 according to the utility model is lower than the height of the first storage and charging position 22, and the internal space of the battery swap station is fully utilized. Preferably, as shown in Figure 9 The first storage and charging position 22 is provided with a plurality of guide columns 221 for providing a guiding and positioning function for the seating of the battery swap battery 5, and a storage and charging base 222 for mounting the charging connector 220 and the guide column 221.

[0040] In order to realize the purpose of the utility model, the hoisting mechanism 30 includes the vertical slide rail 301 perpendicular to the lane 40 and the horizontal slide rail 302 parallel to the lane 40 and can slide back and forth along the vertical slide rail 301, the horizontal slide rail 302 is equipped with the hoisting part 303, the hoisting part 303 is connected with the lifting appliance 304 through the steel rope or chain, the lifting appliance 304 is used for grabbing the battery swap 5, and the lifting appliance 304 has the lifting height greater than the height of the battery swap 5, the length of the steel rope or chain is controlled through the motor (not shown in the figure), so that the lifting height of the lifting appliance 304 can be controlled, and details are not repeated here. Further, since the first storage and charging position 22 is arrayed, in the length direction perpendicular to the lane 40, the first storage and charging position 22 includes two first storage and charging positions 22 in the first row close to the lane 40 and two first storage and charging positions 22 in the second row away from the lane 40; in the direction parallel to the lane 40, the first storage and charging position 22 includes two first storage and charging positions 22 in the first column close to the front of the battery swap heavy truck 4 and two first storage and charging positions 22 in the second column close to the rear direction, and the first column and the second column first storage and charging position 22 are also equipped with the battery swap channel 202, therefore, in the embodiment, the length of the vertical slide rail 301 is at least three times greater than the length of the battery swap 5, and the length of the horizontal slide rail 302 is at least twice greater than the thickness of the battery swap 5.

[0041] Further, as shown in Figure 10 and Figure 11 in the second embodiment, the overhead layer 1 is equipped with the second storage and charging platform 102 below the first storage and charging platform 20, the second storage and charging platform 102 is equipped with the second storage and charging position 103 above and below the battery swap channel 202, and the transfer warehouse 21 is preferably arranged on the second storage and charging platform 102. The advantage of such design is that the compact battery swap station 100 according to the utility model can provide five storage and charging positions, further improving the battery swap supply capacity, and preferably, in the direction parallel to the lane 40, the second storage and charging position 103 is aligned with the two first storage and charging positions 22 in the second row. Specifically, during battery swap, the battery swap 5 in the power shortage state on the battery swap heavy truck 4 is first carried into the transfer warehouse 21, then a battery swap 5 in the full charge state, i.e. in the full power state, is carried from the first storage and charging position 22 or the second storage and charging position 103 to the battery swap heavy truck 4 to provide power for the battery swap heavy truck, and then the battery swap 5 in the power shortage state in the transfer warehouse 21 is carried to the first storage and charging position 22 or the second storage and charging position 103 to be charged, that is, the compact battery swap station 100 according to the utility model does not need to frequently transfer the battery swap 5, the plug-in frequency of the charging connector 220 is reduced, and the service life is improved.

[0042] As shown in Figure 12As shown, in the third embodiment of the utility model, a plurality of charging machines 6 are arranged in the overhead layer 1, the charging machine 6 can be partially located below the first storage charging platform 20, or can be entirely sunk below the first storage charging platform 20, so that the floor area can be further reduced. Meanwhile, in the third embodiment, the bottom of the shell 210 of the transfer warehouse 21 is provided with a plurality of height-adjustable supporting feet 213, since the protective shell 204 is also fixedly installed on the bottom surface through the stand column 11, when the transfer warehouse 21 is directly fixedly installed on the bottom surface, the shell 210 can be selectively fixedly connected with the protective shell 204 or not fixedly connected, and the relative fixation of the transfer warehouse 21 and the first storage charging position 22 can be realized in both ways. The compact charging and battery replacing station 100 of the utility model greatly improves the space utilization, reduces the frequency of warehouse reversing, prolongs the service life of the battery replacing connector, reduces the maintenance cost, and can improve the battery replacing capacity of the battery replacing station, and has obvious progressiveness.
