Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly to a mobile charging pile. Background Art

[0002] The function of a charging pile is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. The charging pile generally provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe on the man-machine interaction operation interface provided by the charging pile to perform operations such as corresponding charging methods, charging time, and printing of fee data. The display screen of the charging pile can display data such as the charging amount, fee, and charging time.

[0003] However, most of the existing charging piles for electric vehicles are fixed. When charging, the vehicle needs to be driven to a designated charging location. However, for parking lots without charging piles, when the electric vehicle urgently needs to replenish power, the vehicle owner still needs to specifically search for a charging station for charging. Or when the existing power of the vehicle is not enough to support it to reach the charging station, a tow truck is needed, which causes great inconvenience to the use of the electric vehicle owner. Therefore, it is necessary to design a mobile charging pile. After the vehicle stops, the mobile charging pile can be moved to the position of the vehicle for charging, so that the corresponding mobile charging pile can be dispatched to the designated position of the vehicle for charging at any time, and it is also more convenient during charging. At present, although there are some mobile charging piles, their structures are bloated and complex, installation and maintenance are very troublesome, and it is not easy to dissipate heat during the charging and discharging process, and the risk coefficient during use is large, there are potential safety hazards. Summary of the Invention

[0004] In order to solve various problems such as the fixed charging piles in the prior art, the complex structure of mobile charging piles, poor heat dissipation performance, and very troublesome assembly and maintenance, the present invention proposes a mobile charging pile to solve the above problems.

[0005] A mobile charging pile includes a base, a battery assembly, a wiring board, and a housing. A plurality of battery assemblies are arranged in an array on the base. Heat dissipation channels and wiring channels are formed between the battery assemblies. The wiring board is movably received in the wiring channel. A heat dissipation fan is correspondingly provided for each battery assembly. One end of the battery assembly provided with the heat dissipation fan faces the heat dissipation channel, and the heat dissipation fans of any two opposite battery assemblies are staggered from each other. The housing covers the battery assembly and is fixed on the base. By reasonably arranging the battery modules to form heat dissipation and wiring channels, the structure of the mobile charging pile is optimized, which is beneficial to installation and maintenance and heat dissipation during use.

[0006] In some specific embodiments, multiple battery modules are arranged in a matrix on the base, and the heat dissipation channels and wiring channels are perpendicular to each other. The matrix arrangement can form a "cross" channel between the battery modules, and the heat dissipation and wiring can be reasonably arranged using this channel.

[0007] In some specific embodiments, the wiring channel divides the heat dissipation channel into two heat dissipation areas. By isolating and dividing the heat dissipation channel with the wiring channel, the relatively two groups of battery modules can be separated, and the heat dissipation of the two areas can be regulated respectively to more effectively control the heat dissipation.

[0008] In some specific embodiments, the battery module includes a battery and a control component arranged one above the other, the battery and the control component are electrically connected, a cooling fan is arranged at one end of the control component, and a wiring terminal is arranged at the other end. The cooperation mode of arranging one above the other can be combined with different combinations, and the position of the control component can be customized to facilitate the control of the position of the heat dissipation air outlet.

[0009] In some specific embodiments, in the heat dissipation area, the two opposite batteries and control components are arranged staggeredly so that the opposite cooling fans are arranged staggeredly up and down. With this arrangement, the exhaust outlets of the two opposite battery modules can be staggered, avoiding the direct blowing of the cooling fans of the two opposite battery modules, which may prevent the hot air from being discharged in time and affect the heat dissipation of the mobile charging pile.

[0010] In some specific embodiments, a blower is arranged at the bottom of the heat dissipation area. The blower at the bottom can effectively discharge the high-temperature gas in the heat dissipation channel, further improving the heat dissipation efficiency.

[0011] In some specific embodiments, the two sides of the heat dissipation channel are lower than the end faces of the components in this direction, and splitters for connecting the wiring board and the battery module are arranged on the two sides of the heat dissipation channel. With this arrangement, a space for accommodating the wires can be formed, the wiring of the battery module can be led to the splitter and further connected into the wiring board, and the wires will not protrude to affect the assembly of the housing.

[0012] In some specific embodiments, tracks are arranged on the inner sides of both sides of the wiring channel, and the wiring board is slidably arranged on the tracks. The slidable structure can facilitate installation and maintenance and reduce internal wiring.

[0013] In some specific embodiments, the housing includes a left housing and a right housing with the heat dissipation channel as the boundary. Grooves corresponding to the heat dissipation channel and the wiring channel are opened on the upper end faces of the left housing and the right housing. A cover plate is arranged on the wiring channel, and lifting lugs are arranged at both ends of the top of the heat dissipation channel. With this arrangement, the wiring channel can be prevented from being exposed to the outside, and the arrangement of the lifting lugs can meet the transportation requirements of the mobile charging pile.

[0014] In some specific embodiments, it further includes walking wheels and a ground lock mechanism, and both the ground lock mechanism and the walking wheels are arranged on the bottom surface of the base. With the walking wheels, the pile body can be conveniently moved, and the setting of the ground lock mechanism can fix the mobile charging pile in a certain area to prevent the mobile charging pile from being moved.

[0015] The present invention provides a mobile charging pile. Through the reasonable arrangement of the battery components, a heat dissipation and wiring channel is formed. At the same time, the staggered arrangement of the opposite battery components can stagger the positions of the fans, avoiding the difficult discharge of the accumulated heat of the battery components. Further, the heat is discharged by the blower at the bottom, greatly improving the heat dissipation performance. The pull-out type wiring board is provided, which solves the problem of the complex and troublesome circuit wiring of the current charging pile body. When wiring, the wiring board can be pulled out to perform wiring externally. At the same time, relying on the cooperation of the walking wheels and the ground lock mechanism on the base, it realizes mobility and positioning and locking, preventing the mobile charging pile from being stolen, greatly facilitating the use of new energy vehicle owners and the management of mobile charging pile owners, solving the problem of difficult and troublesome charging of new energy vehicles, and can be widely promoted and applied.

[0023] To make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Figure 1 The overall structure diagram of a mobile charging pile according to an embodiment of the present invention is shown. As Figure 1 shown, the mobile charging pile includes a pile body 1 and walking wheels 2. The walking wheels 2 are arranged at the four corners of the bottom of the pile body 1 so that the pile body 1 can move. Corresponding holes of a wiring channel 3 and a heat dissipation channel 4 are provided on the upper end surface of the pile body 1. A cover plate 31 is provided on the wiring channel 3. The cover plate 31 is movably provided on the wiring channel. Preferably, a corresponding locking device can also be provided on the upper end surface to lock the cover plate 31 on the upper end surface to prevent outsiders from easily opening the cover plate and damaging the internal wiring board. A heat dissipation channel 4 is provided at a position perpendicular to the wiring channel 3. The top of the heat dissipation channel 4 is hollowed out to facilitate the effective discharge of the heat inside the pile body 1. Lifting lugs 41 are provided on both sides of the pile body 1 at the positions of the heat dissipation channel 4 to facilitate lifting when transporting the mobile charging pile. A plurality of hollowed-out heat dissipation holes are arranged in an array on both sides of the pile body 1, which can increase the air flow inside and outside the pile body and is conducive to the heat dissipation of the pile body. Preferably, the pile body 1 is of a square structure, and the heat dissipation channel 4 and the wiring channel 3 are located in the middle of the square structure on the upper end surface. Alternatively, the structure of the pile body 1 can also be other structures such as a cuboid or other curved surface bodies, etc., and the heat dissipation channel 4 and the wiring channel 3 can also be arranged in other forms according to the internal structure.

[0025] Continue to refer to Figure 2 , Figure 2 The exploded view of a mobile charging pile according to a specific embodiment of the present invention is shown. As Figure 2As shown in the figure, the pile body 1 includes a left shell 11 and a right shell 12. The left shell 11 and the right shell 12 are fixed on the base 5 to form the main structure of the pile body 1. A plurality of groups of battery assemblies 8 are arranged in an array on the base 5. In the figure, 4 groups of battery assemblies 8 constitute the power supply of the mobile charging pile. The 4 groups of battery assemblies are arranged in a matrix, and a wiring channel 3 and a heat dissipation channel 4 are formed between the 4 groups of battery assemblies. Moreover, the periphery of the wiring channel 3 and the heat dissipation channel 4 is separated from the battery assemblies 8 by side plates. The wiring channel 3 requires a relatively large space to accommodate the wiring board 9. The wiring channel 3 divides the heat dissipation channel 4 into two areas. The bottom of the heat dissipation channel 4 is also hollowed out to facilitate heat dissipation. At the same time, a blower 7 is arranged at the bottom to further discharge the heat in the heat dissipation channel 4 to prevent the mobile charging pile from overheating. A ground lock mechanism 6 is also arranged on the base 5 to lock the mobile charging pile and prevent the mobile charging pile from moving during charging or being maliciously stolen.

[0026] In a specific embodiment, Figure 3 shows a schematic cross-sectional view of the heat dissipation channel of a mobile charging pile according to a specific embodiment of the present invention. As Figure 3 shown, the battery assembly 8 specifically includes a battery 82 and a control assembly 81. The length and width dimensions of the control assembly 81 are comparable to those of the battery 82, and it can be placed above or below the battery 82. One end of the control assembly 81 is provided with a heat dissipation fan, and the other end is a wiring terminal electrically connected to the battery 82 for managing and controlling the battery 82. The end provided with the heat dissipation fan faces the heat dissipation channel 4 to discharge the heat generated by the battery 82 into the heat dissipation channel 4. Preferably, the arrangements of two opposite battery assemblies 8 are staggered with each other. As Figure 3 shown in the figure, the control assembly 81 of the left battery assembly on the left is arranged at the bottommost, and the battery 82 and the control assembly are alternately arranged thereon. The battery 82' of the right battery assembly on the right is arranged at the bottommost, and the control assembly 81' and the battery are alternately arranged thereon. This arrangement makes the control assemblies of two opposite battery assemblies 8 staggered up and down, and the heat dissipation fans of the control assemblies do not face each other, which is conducive to the gas flow inside the heat dissipation channel 4. Finally, the hot air in the heat dissipation channel 4 is discharged through the blower 7 at the bottom, and the overall heat dissipation effect is better.

[0027] In a specific embodiment, the wiring channel 3 divides the heat dissipation channel 4 into two areas. In these two areas, the battery assemblies 8 are all arranged alternately with each other so that the heat dissipation fans of the control assemblies are staggered up and down. Correspondingly, the blower 7 is arranged in the two areas respectively with the wiring channel 3 as the boundary. Preferably, the blower 7 adopts an axial flow blower, which can discharge the heat in the heat dissipation channel 4 faster. The blower 7 can be controlled to work during operation by accessing the wiring board 9 through the battery assembly 8.

[0028] Continue to refer to Figure 4 , Figure 4The cross-sectional schematic view of the wiring channel of the mobile charging pile according to a specific embodiment of the present invention is shown. As Figure 4 shown, the wiring board 9 has an "L" shape. Rails 32 are provided on the two inner side walls of the wiring channel 3. The wiring board 9 is movably arranged on the rails 32. Handles 91 are provided at both ends of the upper surface of the wiring board 9, which is convenient for taking out the wiring board 9 from the wiring channel 3. Preferably, positioning mechanisms can be provided on both sides of the wiring board 9, and corresponding fixing mechanisms are provided on the wiring channel 3, which can fix the wiring board 9 when the wiring board 9 is taken out, facilitating wiring or maintenance operations. A self-charging port 92 and an external charging gun interface 93 are also provided on the upper surface of the wiring board 9. The self-charging port 92 is used to charge the battery assembly 8 by using an external interface, and the external charging gun interface 93 is used to connect to the charging port of the electric vehicle to charge the battery of the electric vehicle. Various circuit boards and control devices are arranged on the main board of the wiring board 9, and the wiring is neatly arranged through wire grooves.

[0029] In a specific embodiment, a wire splitter 33 and an emergency stop button 34 are provided on the two outer sides of the wiring channel 3, and the length dimension of the wiring channel 3 is smaller than the maximum distance between two opposite battery assemblies 8 in this direction, so that the side surface of the wiring channel 3 is lower than one end surface of the two side battery assemblies 8. The wiring terminals at the end of the control component of the battery assembly 8 are connected to the wire splitter 33 through a wire groove and then connected to the wiring board 9. The emergency stop button 34 is connected to the control circuit in the wiring board 9 for urgently interrupting the charging task. A hole corresponding to the emergency stop button 34 is provided at the corresponding position of the right housing 12, which is convenient for the user to operate.

[0030] Continue to refer to Figure 5 , Figure 5 The schematic view of the ground lock mechanism according to a specific embodiment of the present invention is shown. As Figure 5 shown, the ground lock mechanism includes an outer sleeve 61, an inner sleeve 62, and a support assembly 63. The inner sleeve 62 is movably sleeved inside the outer sleeve 61, and the support assembly 63 is movably sleeved on the inner sleeve 62. A driving assembly 64 is arranged in the cavity formed by the outer sleeve 61 and the inner sleeve 62, and the base of the driving assembly 64 is fixed to the top of the outer sleeve 61. The end of the driving push rod of the driving assembly 64 is connected to the inner bottom connecting seat of the inner sleeve 62. The outer sleeve 61 and the inner sleeve 62 are connected as the main structure of the ground lock mechanism through the driving assembly 64, making full use of the space formed by the inner and outer sleeves, with a compact structure and convenient installation and debugging. A travel switch 65 is also installed in the cavity formed by the outer sleeve 61 and the inner sleeve 62. The travel switch 65 is used to control the extension length of the driving assembly 64. When the forming switch 65 is triggered, it indicates that the ground lock mechanism has completed the locking work.

[0031] In a specific embodiment, the ground lock mechanism 6 is arranged at the bottom of the wiring channel 3. The outer sleeve 61 is fixed to the base 5, and the access wiring board 9 provides power supply and control instructions for the ground lock mechanism 6. When the mobile charging pile is transported to the designated charging address and the charging gun is connected to start charging the electric vehicle, an instruction is issued to make the ground lock mechanism work. The inner sleeve 62 runs downward under the pushing action of the driving component 64, and at the same time drives the support component 63 to move downward. The support component 63 contacts the ground, and the trigger rod of the travel switch 65 contacts the support component 63, triggering the control switch. The control switch sends a signal to stop the push rod of the driving component 64 from continuing to run. At this time, the self-weight of the mobile charging pile mainly acts on the ground lock mechanism, and the walking wheels 2 do not contact the ground or only partially contact the ground, forming the function of a ground lock, and the mobile charging pile cannot be pushed and moved through the walking wheels 2. This locked state is as shown in Figure 6 the mobile charging pile locking state diagram according to a specific embodiment of the present invention shown.

[0032] The present invention proposes a mobile charging pile. The battery components of the mobile charging pile are arranged on the base in a matrix arrangement. Based on this arrangement, heat dissipation and wiring channels are formed. And one end of the battery components with heat dissipation fans is arranged opposite to each other and uses the up-and-down arrangement of the batteries and control components to stagger the up-and-down arrangement of the heat dissipation fans, avoiding the difficulty of discharging the accumulated heat of the battery components. Further, the heat is discharged by the fan at the bottom, greatly improving the heat dissipation performance. The pull-out type wiring board is provided, which can greatly facilitate the operation when maintaining or installing the wiring of the mobile charging pile. The wiring board can be pulled out of the interior of the pile body, avoiding the problem that it is not easy to operate due to the small internal space when maintaining or wiring the internal control circuit of the pile body. At the same time, relying on the cooperation of the walking wheels on the base and the ground lock mechanism, the mobility of the pile body is realized, and the ground lock mechanism is used to lock the pile body during use to prevent the mobile charging pile from being stolen or accidentally moved, which greatly facilitates the use of new energy vehicle owners and the management of mobile charging pile owners. The good heat dissipation ability can also ensure that the mobile charging pile maintains a stable state during operation, and also improves the safety of using the mobile charging pile.

[0033] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made without creative efforts by those skilled in the art are still within the protection scope of the present invention.
