People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The charging pile display can display data such as charging amount, cost, and charging time; at present, a common new energy charging pile is composed of a chassis, solar panels, energy storage battery packs, charging guns and other equipment. When the new energy charging pile is in use, the solar panels need to first convert solar energy into DC power, and then transfer the DC power to the energy storage battery pack for temporary storage. When the charging gun needs to charge the electric car, the battery pack is converted into DC power. The DC power in the energy storage battery pack can be released; the relevant technology of the energy storage battery pack is disclosed in the Chinese patent library.

DETAILED DESCRIPTION

[0033] In order to clearly understand the technical solution of the present application, a new energy charging pile battery pack and a charging pile provided by the present application will be described in detail below in combination with specific embodiments and drawings.

[0034] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more than two.

[0035] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Example 1

[0036] This embodiment provides a new energy charging pile battery pack, referring to Figure 1 , which shows a three-dimensional structural schematic diagram of a new energy charging pile battery pack. It can be seen from the figure that the new energy charging pile battery pack includes an outer shell 1, and is further combined with Figure 2 The schematic diagram of the partial exploded structure of the battery pack of the new energy charging pile shown in the figure shows that a plurality of placement grooves 2 are sequentially opened on the front side of the outer shell 1 from top to bottom (the number of placement grooves 2 is set to four in this embodiment), and a single battery 3 is slidably adapted in each placement groove 2. The multiple batteries 3 respectively placed in the corresponding placement grooves 2 together constitute a battery module, and a base 4 is formed at the bottom of the outer shell 1; a cooling component is installed on the outer side of the outer shell 1, and the cold source generated by the cooling component is used to dissipate heat from the battery module in the outer shell 1; the specific structure of the cooling component is as follows.

[0037] refer to Figure 3, which is a schematic diagram of the three-dimensional structure of the cooling component. It can be seen from the figure that the cooling component includes a guide pipe 5, and the entire guide pipe 5 is arranged on the two side surfaces and the top surface of the outer shell 1 in a serpentine manner; the starting end of the guide pipe 5 is connected to an exhaust fan 6 (the existing product can be directly used), the tail end of the guide pipe 5 is connected to an air outlet nozzle 7, and the guide pipe 5 is also connected to a refrigerator (the existing refrigerator can be used, which is not shown in the figure); the present invention monitors the temperature in the outer shell 1 at all times through a temperature sensor. Once the electric When the battery 3 becomes hot, the exhaust fan 6 and the refrigerator are started. Under the action of the exhaust fan 6, the hot air in the outer shell 1 enters the guide duct 5 from the air outlet nozzle 7. The hot air is cooled into cold air after passing through the refrigerator, and the cold air is discharged from the air outlet of the exhaust fan 6. On the one hand, the cold air achieves preliminary heat dissipation to the battery 3 in the outer shell 1 during the flow in the guide duct 5. On the other hand, the cold air ejected from the exhaust fan 6 is gradually mixed with the surrounding hot air, so that the surrounding hot air is gradually converted into cold air, thereby further cooling the battery 3.

[0038] Compared with the prior art, the present invention adds a cooling component, which can achieve preliminary heat dissipation of the battery 3 by allowing cold air to flow in the serpentine guide duct 5, and then directly cool and dissipate the heat of the battery 3 through the surrounding cold air, thereby solving the problem that the existing battery 3 group does not disclose how to dissipate the heat of the battery 3 group.

[0039] After a single battery 3 is inserted into the corresponding placement slot 2, the battery 3 needs to be locked in time by a locking assembly; for this purpose, the present invention further designs a locking assembly, referring to Figure 4 , which is a schematic diagram of the installation structure of the locking component. It can be seen from the figure that a single locking component is installed on one side of the corresponding placement slot 2, and the locking component is used to lock or unlock a single battery 3; the specific structure of the locking component is as follows.

[0040] refer to Figure 5 , Figure 5 The exploded structure diagram of the locking assembly, the outer shell 1, and the battery 3 is shown. It can be seen from the figure that a locking hole 8 is formed on one side of the placement slot 2, and a notch slot 9 is formed at one end of the battery 3. After the battery 3 is placed in the placement slot 2, the notch slot 9 is opposite to the locking hole 8; Figure 6-7 ,in, Figure 6 The figure shows the assembly structure diagram of the locking assembly and the battery 3. Figure 7What is shown is a schematic diagram of the exploded structure of the locking assembly. It can be seen from the above two figures that the locking assembly includes a sliding sleeve 10, a wedge block 11 is slidably connected in the sliding sleeve 10, a through groove 12 is opened along the length direction of the wedge block 11, and a U-shaped arm 13 is slidably adapted in the through groove 12, and the U-shaped arm 13 passes through the top and bottom of the sliding sleeve 10 in a vertical sliding manner; a first elastic component 14 (such as a spring, etc.) is connected between the sliding sleeve 10 and the U-shaped arm 13, and a second elastic component 15 is connected between the sliding sleeve 10 and the wedge block 11; the U-shaped arm 13 is fixedly connected to the outer shell 1, and the wedge block 11 is opposite to the locking hole 8, and the slope surface of the wedge block 11 faces the entrance direction of the placement groove 2; when the first elastic component 14 and the second elastic component 15 are in a natural state, the wedge block 11 passes through the locking hole 8 and is placed in the notch groove 9, and the battery 3 is locked by the mutual adaptation of the wedge block 11 and the notch groove 9.

[0041] When the locking assembly is ready to lock the battery 3, the first method is to pull the tail end of the wedge block 11 so that the through slot 12 of the wedge block 11 translates along the a1 direction in the sliding sleeve 10. At this time, the through slot 12 of the wedge block 11 slides over the U-shaped arm 13 along the a1 direction until the wedge block 11 moves away from the notch groove 9 to one side and enters the position behind the placement groove 2. At this time, the battery 3 can be pushed into the corresponding placement groove 2, and then the wedge block 11 is released. The wedge block 11 returns to its original position along the a2 direction under the driving action of the second elastic component 15 until the wedge block 11 is placed in the notch groove 9 and the battery 3 is locked. The second method is to push the sliding sleeve 10 on the U-shaped arm 13 to move along the direction b1. During the movement, the sliding sleeve 10 drives the wedge block 11 to move along the direction b1 accordingly, until the wedge block 11 moves downward out of the notch groove 9 and enters the position behind the placement groove 2. At this time, the battery 3 is pushed into the corresponding placement groove 2. At this time, the battery 3 can be pushed into the corresponding placement groove 2, and the sliding sleeve 10 is immediately released. The sliding sleeve 10 returns to its original position along the direction b2 under the driving action of the first elastic component 14 until the wedge block 11 is placed in the notch groove 9 and the battery 3 is locked.

[0042] When a single battery 3 is damaged and needs to be repaired, a single locking assembly can lock or unlock the single battery 3 according to the above situation; however, once the entire battery module is damaged, it is a waste of time and reduces work efficiency to disassemble and assemble the single batteries 3 one by one; therefore, as an optimization of the locking assembly, reference is made to Figure 8-9 ,in, Figure 8 The figure shows the assembly structure diagram of the optimized locking assembly. Fig. 9The three-dimensional structure diagram of the lifting ring group and the third elastic component is shown. It can be seen from the above two figures that the locking assembly also includes a lifting ring group, which is composed of four single rings 16 connected in series in sequence, and the four single rings 16 are respectively movably sleeved on the outer surfaces of the four sliding sleeves 10; the single ring 16 at the bottom is fixedly connected with the third elastic component; wherein the third elastic component includes a support seat 17, the support seat 17 and the slide groove formed on the outer shell 1 form a vertical sliding connection, and the support seat 17 is fixedly connected with the outer shell 1 through a spring; a handle 18 is fixedly connected to the support seat 17. When the entire battery module needs to be disassembled, the handle 18 is pulled downward or upward, and the four single rings 16 of the lifting ring group synchronously pull the four sliding sleeves 10 downward or upward, thereby unlocking or locking the entire battery module.

It can be seen from the figure that the charging pile includes a chassis 19, and a charging gun 20 is provided on one side of the chassis 19. The charging gun 20 is used to charge the electric vehicle when in use, and the charging gun 20 can be inserted into the charging pile port of the chassis 19 when not in use; further reference Fig.11 The overall structural diagram of the charging pile from the second perspective shown in Fig.12 The schematic diagram of the partial structure of the charging pile shown in the figure, the charging pile also includes the new energy charging pile battery pack in Example 1, the new energy charging pile battery pack is installed on the carrier 21, and the carrier 21 is fixedly connected to the inner cavity of the chassis 19; the discharge end of the new energy charging pile battery pack is electrically connected to the charging pile port, and the charging end of the new energy charging pile battery pack is electrically connected to the solar panel (the solar cell directly uses the common existing technology on the market, which will not be repeated here); a dustproof door is connected to the carrier 21, and the dustproof door can be used to block the inspection port on the chassis 19. The specific structure of the dustproof door is as follows. It is worth noting that a transformer is also connected to the charging pile port. Under normal circumstances, the transformer transforms the external power to meet the use requirements of the charging pile; once there is no power or the transformer is damaged, the new energy charging pile battery pack here is used for emergency purposes.
