Detailed Implementation

[0031] Because public service charging piles typically require high output power and the expansion capacity of power distribution networks is limited, the deployment quantity and operating power of mobile charging piles are constrained by the carrying capacity of power supply lines.

[0032] In view of this, this solution provides a mobile charging pile with a split energy storage module, including a charging main body and multiple energy storage modules 10.

[0033] The following combination Figures 1-6 The structure and shape of the mobile charging pile with a split energy storage module provided in this embodiment are described in detail below:

[0034] The energy storage module 10 includes an energy storage battery 100 and a transfer mechanism 200; the energy storage battery 100 is detachably electrically connected to the charging body and is used to deliver electrical energy to the charging body; the transfer mechanism 200 is used to assist the energy storage battery 100 in transferring between the charging body and an external charging device; multiple energy storage modules 10 can be used in rotation to keep multiple energy storage batteries 100 in the power output and replenishment states respectively.

[0035] In this embodiment, by detachably connecting the energy storage battery 100 to the charging body, and with the assistance of the transfer mechanism 200, the energy storage battery 100 with a charge level below the threshold can be moved to an external charging device for recharging, thereby realizing the mode of off-site recharging and local power supply, thus solving the problem that the number of mobile charging piles deployed and the operating power are limited by the carrying capacity of the power supply line.

[0036] In addition, by setting up multiple energy storage modules 10 that can take turns supplying power to the charging main body, at least one energy storage battery 100 in the energy storage module 10 can supply power to the charging main body at any given time. The energy storage battery 100 with a power level below the threshold can be moved to an external charging device for recharging with the assistance of the transfer mechanism 200. This achieves a continuous operation mode of supplying power to the charging main body while simultaneously recharging, thereby avoiding the problem of service interruption caused by recharging.

[0037] In addition, by setting up multiple energy storage modules 10 that can take turns supplying power to the charging body, during this process, the energy storage battery 100 with a power level below the threshold is moved to the external charging equipment for recharging with the assistance of the transfer mechanism 200, which effectively reduces the weight and manpower requirements of a single recharging operation.

[0038] To facilitate the movement of the energy storage battery 100 between the charging unit and the external charging device:

[0039] like Figures 3-5 As shown, the transfer mechanism 200 includes a roller 210 and a lifting structure 220; the roller 210 is installed at the bottom of the energy storage battery 100 and is used to enable the energy storage battery 100 to move in the horizontal direction; the lifting structure 220 is installed on the energy storage battery 100 and is used to drive the energy storage battery 100 to move in the vertical direction.

[0040] In this embodiment, rollers 210 are provided at the bottom of the energy storage battery 100 to assist the energy storage battery 100 in moving horizontally; at the same time, the lifting structure 220 installed on the energy storage battery drives the energy storage battery 100 to move vertically, thereby smoothly crossing the area with a certain height difference, thus assisting the energy storage battery 100 in moving between the charging body and the external charging device.

[0041] To ensure that the lifting structure 220 and the auxiliary energy storage battery 100 can smoothly cross areas with a certain height difference:

[0042] like Figures 3-5 As shown, the lifting structure 220 includes a lifting push rod 221, an adapter 222, and a support base 223; the lifting push rod 221 is installed on the energy storage battery 100; one end of the adapter 222 is connected to the telescopic end of the lifting push rod 221, and the other end is hinged to the support base 223.

[0043] In this embodiment, when the energy storage battery 100 needs to cross an upward-raising area, the lifting push rod 221 drives the support base 223 to move downward through the adapter 222. After the support base 223 contacts the ground, it drives the energy storage battery 100 to move upward through the adapter 222 and the lifting push rod 221. After the energy storage battery 100 drives the roller 210 to cross the raised area, it drives the adapter 222 to rotate relative to the support base 223, so that the energy storage battery 100 moves towards the raised area. After the energy storage battery 100 drives the roller 210 to contact the raised area, it continues to drive the energy storage battery 100 to rotate with the roller 210 as the fulcrum. After the energy storage battery 100 rotates to a set angle, the lifting push rod 221 drives the support base 223 to reset through the adapter 222. This step can be applied to moving the energy storage battery 100 onto a vehicle.

[0044] When the energy storage battery 100 needs to cross the downward-lowering area, the energy storage battery 100 rotates around the roller 210 as a fulcrum. After the energy storage battery 100 rotates to a set angle, the lifting push rod 221 drives the support base 223 to move towards the lowering area through the adapter 222. After the support base 223 contacts the lowering area, it drives the adapter 222 to rotate relative to the support base 223, so that the energy storage battery 100 moves towards the lowering area. Then, the lifting push rod 221 retracts to drive the energy storage battery 100 to move downward until the roller 210 contacts the lowering area. This step can be applied to moving the energy storage battery 100 on the vehicle to the ground.

[0045] To limit the angle at which the energy storage battery 100 rotates toward the side with the lower drop as it traverses a drop region:

[0046] like Figure 3 and Figure 5 As shown, the lifting structure 220 also includes a limiting rod 224; the limiting rod 224 is connected to the adapter 222 and is inclined toward the support base 223 to limit the rotation angle of the adapter 222.

[0047] In this embodiment, when the energy storage battery 100 rotates towards the lower drop side during the process of crossing the drop area, the energy storage battery 100 drives the limiting rod 224 to rotate through the lifting push rod 221 and the adapter seat 222. After the rotation angle of the energy storage battery 100 reaches the threshold, the end of the limiting rod 224 away from the adapter seat 222 abuts against the support base 223, thereby limiting the angle of rotation of the energy storage battery 100 towards the lower drop side during the process of crossing the drop area, thereby preventing the energy storage battery 100 from tipping over due to excessive rotation angle.

[0048] To reduce damage caused by the contact between the limiting rod 224 and the support base 223:

[0049] like Figure 3 and Figure 5As shown, the lifting structure 220 also includes a limiting seat 225; the limiting seat 225 is hinged to the end of the limiting rod 224 away from the adapter seat 222, and is used to increase the contact area between the limiting rod 224 and the support base 223.

[0050] In this embodiment, by hinged to a limiting seat 225 at the end of the limiting rod 224 away from the adapter seat 222, the contact area between the limiting rod 224 and the support base 223 is increased, thereby reducing the pressure per unit area of ​​the limiting rod 224 on the support base 223, and thus reducing the damage caused by the limiting rod 224 during the contact process with the support base 223.

[0051] To prevent unauthorized personnel from moving the energy storage battery 100:

[0052] like Figures 1-2 As shown, the energy storage module 10 also includes a support frame 300; the support frame 300 includes a base 310, a top seat 320, and a connecting rod 330; the lifting structure 220 also includes a lifting top seat 226; a first limiting groove is provided on the base 310; the first limiting groove can be slidably fitted onto the support base 223; a second limiting groove is provided on the top seat 320; the second limiting groove can be slidably fitted onto the lifting top seat 226; the first limiting groove and the second limiting groove are arranged at an angle in the horizontal plane to limit the movement of the energy storage battery 100 in the horizontal direction; one end of the connecting rod 330 is connected to the base 310, and the other end is connected to the top seat 320.

[0053] To control the extension or retraction of the lifting push rod 221:

[0054] like Figures 1-4 As shown, the lifting structure 220 also includes a controller; the controller is installed in the energy storage battery and is electrically connected to the lifting push rod 221, and is used to control the extension or retraction of the lifting push rod 221; the controller is equipped with an electronic combination lock to prevent unauthorized personnel from driving the controller.

[0055] In this embodiment, when the energy storage battery 100 returns to its reset position, the roller 210 assists the energy storage battery 100 in moving into the support frame 300. During this process, the support base 223 inserts into the second limiting groove, and at the same time, the lifting top seat 226 moves below the first limiting groove. Then, the lifting push rod 221 drives the support base 223 to move downward through the adapter seat 222. After the support base 223 contacts the first limiting groove, the lifting push rod 221 drives the energy storage battery 100 to move upward in the opposite direction. The energy storage battery 100 drives the lifting top seat 226 to insert into the second limiting groove. The first limiting groove and the second limiting groove are arranged at an angle in the horizontal plane to restrict the movement of the energy storage battery 100 in the horizontal direction, thereby preventing non-operators from moving the energy storage battery 100.

[0056] In addition, after resetting, the energy storage battery 100 is in an overhead deployment state, which increases the distance between the energy storage battery 100 and the ground, thereby preventing water damage to the energy storage battery 100 after water accumulation at the temporary site, thus improving the applicability of the device.

[0057] To drive the energy storage battery 100 to move:

[0058] like Figures 3-6 As shown, the transfer mechanism 200 also includes a grip structure 230; the grip structure 230 is mounted on the energy storage battery 100 and is used to apply driving force to the energy storage battery 100.

[0059] To adapt to the different gripping position requirements of various working environments:

[0060] like Figure 6 As shown, the grip structure 230 includes a conversion support 231 and an offset grip 232; the roller 210 and the limiting seat 225 are respectively located on both sides of the energy storage battery 100 to form a moving side and a supporting side on both sides of the energy storage battery 100; the conversion support 231 is connected to the energy storage battery 100; the offset grip 232 is slidably inserted into the conversion support 231 so that its gripping end extends toward the moving side or the supporting side.

[0061] To prevent uncontrollable slippage of the offset grip 232:

[0062] like Figure 6 As shown, the grip structure 230 also includes a positioning pin 233; the outer surface of the offset grip 232 is provided with at least two positioning holes; the positioning pin 233 is slidably inserted into the conversion support 231 and slidably inserted into the positioning holes, for connecting and fixing the conversion support 231 and the offset grip 232.

[0063] To increase the friction between the offset grip 232 and the operator:

[0064] like Figure 6 As shown, the grip structure 230 also includes two anti-slip grip sleeves 234; both anti-slip grip sleeves 234 are fitted onto the offset grip 232 to increase the coefficient of friction at the gripping end of the offset grip 232.

[0065] In this embodiment, when it is necessary to move the energy storage battery 100 horizontally, the offset handle 232 is moved along the conversion support 231 so that the gripping end of the offset handle 232 extends out of the energy storage battery 100 from the support side away from the roller 210. Then, the positioning pin 233 is inserted into the positioning hole on the offset handle 232 so that the offset handle 232 is fixed to the conversion support 231. Then, the operator drives the energy storage battery 100 to rotate around the roller 210 through the offset handle 232 so that the support side of the energy storage battery 100 is separated from the ground. Then, with the cooperation of the roller 210, the energy storage battery 100 is moved horizontally. During this process, after the offset handle 232 loses its supporting force, the support side of the energy storage battery 100 contacts the ground, thereby preventing the energy storage battery 100 from tipping over.

[0066] In addition, by setting the limiting seat 225 on the supporting side of the energy storage battery 100, when the supporting side of the energy storage battery 100 is in contact with the ground, the end of the supporting base 223 that is close to the supporting side first contacts the ground, and then the supporting base 223 rotates relative to the adapter 222 and contacts the limiting seat 225, thereby supporting the energy storage battery 100 in the air.

[0067] When it is necessary to move the energy storage battery 100 across the drop area, the offset handle 232 is moved along the conversion support 231 so that the gripping end of the offset handle 232 extends out of the energy storage battery 100 from the moving side near the roller 210, so that the operator can move the roller 210 to the higher side of the drop or away from the higher side of the drop, thereby facilitating the movement of the energy storage battery 100 across the drop area.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
