[0002] With the rapid development of new energy vehicles, there are more and more electric heavy trucks or electric engineering vehicles adopting charging mode or charging and swapping integrated mode, and the corresponding number of charging stations or swapping stations is also increasing rapidly. The construction of charging stations and swapping stations involves conditions such as land approval, civil engineering, and power facilities in the early stage, with large initial investment and long construction period. Some newly built charging stations or swapping stations may also need to charge electric vehicles or provide temporary power for the chargers supporting the swapping stations without power supply.

[0003] In the prior art, usually, electric vehicles directly go to swapping stations or charging stations for energy replenishment, or a battery delivery vehicle is used to provide a mobile swapping energy replenishment solution. As is well known, the initial investment cost of swapping stations and charging stations is high, with high requirements for civil engineering and power, and long construction period. And using a battery delivery vehicle to supply power requires swapping through swapping equipment, which virtually increases the investment cost. On the other hand, large-capacity power batteries used in vehicles such as swapping heavy trucks and swapping mining trucks are not fully utilized. For example, they are discarded and recycled when the battery capacity is insufficient, resulting in waste.

[0004] Based on the above problems, there is an urgent need to design a mobile power supply platform and a mobile power supply vehicle, which use power batteries as energy storage units to provide electric energy supplement for electric vehicles under the condition of no power resources or insufficient power resources, realize the cascade utilization of power batteries, and at the same time solve the technical problem that energy storage batteries are not easy to replace in the existing mobile energy storage technology.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 6 As shown, this utility model embodiment provides a mobile power supply platform 100 for providing power to electric vehicles or electrical equipment that require charging. The mobile power supply platform 100 includes a mobile carrier 20 and multiple energy storage units 5 disposed on the mobile carrier 20. Each energy storage unit 5 is connected to a base 10 between itself and the mobile carrier 20, and the energy storage units 5 and the base 10 are detachably connected. Each base 10 includes a base 1 with two long sides 101 and two short sides 102. The base 1 is preferably a frame-shaped connector. The top surface (not labeled) of the base 1 supports the energy storage units 5. An output section 6 is provided on the lower side of one of the short sides 102 of the base 1. Specifically, the short side 102 has an output section 6 on the lower side of the top surface of the base 1. The long sides 101 of adjacent bases 10 are parallel to each other, and the distance d between adjacent long sides 101 of adjacent bases 10 is not greater than the length of the short side 102. Preferably, The distance between the energy storage units is not less than 5 cm to ensure that the energy storage units 5 have sufficient space for heat dissipation and to ensure that there is enough operating space when disassembling and replacing them so that the energy storage units 5 do not interfere with each other, but are not isolated too far apart to waste the storage space on the mobile carrier 20. In other words, the distance between two adjacent energy storage units 5 is not greater than the thickness of a single energy storage unit 5. This allows the mobile carrier 20 to store as many energy storage units 5 as possible to obtain a mobile power transmission platform 100 with a higher energy density and improve the charging and power supply service capabilities of the mobile power transmission platform 100.

[0031] The energy storage unit 5 is detachably connected to the base 10. This design allows the energy storage unit 5 to be removed from the mobile carrier 20 for replacement or repair. Furthermore, to achieve this, the base 1 extends upwards from its top surface and is provided with multiple first guiding and positioning devices 11 at intervals. These guiding and positioning devices 11 ensure that each energy storage unit 5 is accurately installed in a designated position. Preferably, the first guiding and positioning device 11 includes front and rear guide posts 111 on the two long sides 101 and left and right guide posts 112 on the two short sides 102. The front and rear guide columns 111 are used to limit the energy storage unit 5 in the front and rear directions, and the left and right guide columns 112 are used to limit the energy storage unit 5 in the left and right directions. In this embodiment, the first guiding and positioning device 11 is a columnar support member with a guide slope. A frame structure is provided on the inner side of the bottom of the energy storage unit 5. The energy storage unit 5 can be guided and positioned on the base 1 by matching the columnar support member with the frame structure. Preferably, the front and rear guide columns 111 and the left and right guide columns 112 have the same height and are all even numbers.

[0032] Furthermore, a locking mechanism 15 is provided on the front and rear guide pillars 111. The locking mechanism 15 is used to fix the energy storage unit 5 to the base 10. Specifically, the locking mechanism 15 preferably presses the bottom of the energy storage unit 5 against the base 10 in the vertical direction. At the same time, since the first guide positioning device 11 restricts the displacement of the energy storage unit 5 relative to the base 10 in the horizontal direction, in other words, the positioning of the energy storage unit 5 in the front-back, left-right, and up-down directions can be achieved through the first guide positioning device 11 and the locking mechanism 15. The locking mechanism 15 includes a driving part 151 installed on the front and rear guide pillars 111 and a locking part 152 that can rotate or extend and retract after being driven by the driving part 151. The locking part 152 can fix the energy storage unit 5 to the base 1 when needed. Obviously, in some other embodiments, the locking mechanism 15 may also be set separately instead of being set on the front and rear guide pillars 111, which will not be described in detail here. Furthermore, in some embodiments, the mobile carrier 20 is also provided with a control cabinet 4. The control cabinet 4 is electrically connected to the energy storage units 5 on each base 10 and is also electrically connected to each locking mechanism 15. The control cabinet 4 is used to monitor and identify the power usage of each energy storage unit 5, realize energy scheduling and allocation, and control the opening and closing of each locking mechanism 15. This will not be elaborated here.

[0033] Preferably, the long side 101 of the base 1 is further provided with a second guiding and positioning device 13 facing upwards, and the height of the second guiding and positioning device 13 is lower than the height of the first guiding and positioning device 11. When the energy storage unit 5 is installed on the base 1 from top to bottom, the first guiding and positioning device 11 first plays a coarse guiding role and makes priority contact with the energy storage unit 5 for guidance. Subsequently, as the energy storage unit 5 continues to descend, the second guiding and positioning device 13 makes contact with the energy storage unit 5 and plays a fine guiding role.

[0034] The output section 6 is provided with at least one discharge connector 61 with an opening facing outwards from the base 1. Figure 3The discharge connector 61 shown is one end of the cable connecting to the discharge connector 61, and the other end is facing outwards, preferably horizontally. A first electrical connector 12 is provided on the base 1, and a second electrical connector (not shown) electrically matched with the first electrical connector 12 is provided at the bottom of the energy storage unit 5. The discharge connector 61 in the output section 6 is electrically connected to the first electrical connector 12 via the aforementioned cable, meaning that the energy storage unit 5 located on the base 1 can be electrically connected via the first electrical connector 12, enabling the output of electrical energy from the energy storage unit 5 from the first electrical connector 12 for charging or supplying power to electric vehicles or other electrical equipment that require charging. A cable with a charging gun can be plugged into the first electrical connector 12. Preferably, the discharge connector 61 includes a first discharge connector 611 and a second discharge connector 612, thereby enabling the simultaneous connection of two charging cables.

[0035] Furthermore, the output unit 6 includes an output housing 60 on which the discharge connector 61 is mounted, and a discharge shield 62 rotatably connected to the output housing 60 for protecting the discharge connector 61. Preferably, the discharge shield 62 is a cover that is hinged to the output housing 60 via a hinge 63. When flipped open outwards, the discharge connector 61 can be exposed. When the discharge connector 61 is not needed for charging, the discharge shield 62 serves to prevent dust, water, and electric shock.

[0036] Furthermore, an input section 7 is provided on the lower side of the other short side 102 of the base 1. The input section 7 contains at least one charging connector (not shown). Similar to the output section 6, the input section 7 includes an input housing 70 for mounting the charging connector and a charging shield 72 rotatably connected to the input housing 70 to protect the charging connector. The energy storage unit 5 located on the base 1 can be charged via the charging connector. Clearly, the presence of a charging connector on the base 1 does not prevent the energy storage unit 5 from being directly replaced from the base 1.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, the frame-shaped base 1 has two long sides 101 and two short sides 102, each with a certain height. The long side 101 includes a long upper beam 101a, a long lower beam 101b parallel to the long upper beam 101a, and multiple longitudinal beams 101c connecting the long upper beam 101a and the long lower beam 101b. Similarly, the short side 102 also includes a short upper beam 102a and a short lower beam 102b. The aforementioned output box 60 and input box 70 are preferably disposed between the short upper beam 102a and the short lower beam 102b. The base 1 designed in this way has a more robust and reliable structure, and the base 1 designed in this way is also convenient for detachable connection with the mobile carrier 20.

[0038] The purpose of this utility model is also to provide a mobile power transmission vehicle, which includes a front unit 600 and a mobile power transmission platform 100 as described above, detachably connected to the front unit 600. In some embodiments, the mobile power transmission platform 100 can be selectively connected to the front unit 600 in the form of a trailer. In other embodiments, the mobile power transmission platform 100 can also be used as part of a trailer and have foldable fixed support legs, which will not be elaborated further. Through the mobile power transmission platform and mobile power transmission vehicle conforming to this utility model, the power battery is compactly and detachably installed as an energy storage unit 5 on the mobile device, realizing a mobile and high-energy-density charging device with good application prospects. Furthermore, the power batteries discarded from battery-swapping heavy trucks and mining trucks can be reused in this mobile power transmission platform and mobile power transmission vehicle, realizing mobile charging while fully utilizing the economic value of large-volume power batteries, contributing to energy conservation and emission reduction, and promoting the healthy development of the new energy industry.

Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
