Description

Technical Field

[0001] The present invention relates to the technical field of charging, and in particular to a charging device for mobile energy storage equipment. Background Art

[0002] With the hot new energy vehicle market, the number of public charging piles is still insufficient at home and abroad, and the ratio of new energy vehicles to charging piles is seriously unbalanced. In the face of the growing number of new energy vehicle users, how to solve users' mileage anxiety and charging uncertainty has become a focal issue. At this time, mobile energy storage equipment came into being, aiming to solve the problem of difficulty in charging new energy vehicles. The mobile energy storage equipment has a frame and four tires. By integrating energy storage batteries and charging piles into equipment with dynamic mobility, the "electric active car search" charging service is realized. After the mobile energy storage device completes charging of the new energy vehicle, the power in the mobile energy storage device will decrease, and the charging device is required to replenish the power of the mobile energy storage device. Specifically: When the power inside the mobile energy storage device decreases and needs to be charged, the mobile energy storage device will use the sensing system to sense the position of the charging device and automatically move to the charging device. At this time, the charging device pushes out the charging connector to connect the charging connector with the charging interface of the mobile energy storage device and power the mobile energy storage device.

[0003] A Chinese patent application document with publication number CN115991109A discloses an automatic charging device for an AGV cart, including a shell, a cart position detection module, a charging port and a charging port retractable mechanism, wherein the cart position detection module is installed above the shell, the charging port and the charging port retractable mechanism are installed in the shell, and the charging port retractable mechanism is connected to the charging port; when the cart position detection module detects that the cart enters the charging position, the charging port retractable mechanism controls the charging port to be pushed out of the shell, thereby connecting the charging port to the cart and charging the cart; when the cart leaves the charging position, the charging port retractable mechanism controls the charging port to retract into the shell. This invention has the advantages of enabling the cart to be automatically charged when it is at the charging pile, reducing personnel operations, and improving work efficiency.

[0004] However, the above patent still has the following shortcomings: when the mobile energy storage device equipped with four tires is moved to the position of the new energy vehicle, the tires of the mobile energy storage device are prone to gas leakage due to some reasons, such as: gas penetration, temperature change, wheel hub sealing problem, valve core leakage, puncture by sharp objects on the road surface, etc., and once the gas in the tire leaks, it will cause the mobile energy storage device to tilt and the overall height to drop, so that the charging interface of the mobile energy storage device and the charging connector of the charging device are misaligned, thereby affecting the normal charging of the mobile energy storage device.

[0031] like Figures 1 to 10As shown, the charging device for mobile energy storage equipment of the present invention includes a mounting seat 1, a charging mechanism 2, a wire management member 3 and an adjustment mechanism 4. The charging mechanism 2 is connected to the mounting seat 1. The charging mechanism 2 has a charging connector 23 and a connection wire 25. The charging connector 23 can be plugged into the charging socket on the mobile energy storage device, so as to charge the mobile energy storage device. The connection wire 25 is provided with a plug. The connection wire 25 can be connected to an external power source through the plug, so as to charge the mobile energy storage device through the charging connector 23. The wire management member 3 is connected to the charging mechanism 2 and is used to organize the connection wire 25 to avoid the connection wire 25 from being entangled. The adjustment mechanism 4 is connected to the charging mechanism 2 and can adjust the charging connector 23 according to the inclination angle and height of the mobile energy storage device so that the charging connector 23 can be aligned with the charging interface on the mobile energy storage device and then plugged.

[0032] like Figures 1 to 5 As shown, the charging mechanism 2 includes an electrical box 21, a pushing member 22 and a positioning rod 24. The electrical box 21 is plugged into the mounting base 1. The mounting base 1 is provided with a slide rail 11. The pushing member 22 is connected to the slide rail 11. The pushing member 22 is a cylinder. The telescopic end of the pushing member 22 is connected to the electrical box 21. The pushing member 22 can push the electrical box 21 out of the mounting base 1. The charging connector 23, the positioning rod 24 and the connecting wire 25 are all connected to the electrical box 21. When the electrical box 21 moves, it can drive the charging connector 23 to be plugged into the charging interface on the mobile energy storage device.

[0033] Continue to refer Figures 1 to 5 As shown, an electrical device (not shown in the figure) is connected to the electrical box 21, and the electrical device is connected to the charging connector 23 through an electric wire. The connecting wire 25 is connected to the electrical device, so that after the connecting wire 25 is connected to the power supply, the mobile energy storage device can be charged through the connecting wire 25, the electrical device and the charging connector 23. A positioning rod 24 is connected to the electrical box 21, and the mobile energy storage device can sense the position of the positioning rod 24 through the sensing system, so that the mobile energy storage device can be moved to the corresponding position of the charging device, so as to charge the mobile energy storage device.

[0034] like Figure 3 and Figure 4As shown, the wire management member 3 includes a limiting portion 31 and an elastic portion 32, the elastic portion 32 is connected to the mounting seat 1, the elastic portion 32 is a telescopic rod with a built-in spring, the limiting portion 31 is connected to the telescopic end of the elastic portion 32, the connecting wire 25 passes through the limiting portion 31, when the electrical box 21 drives the charging connector 23 to extend out of the mounting seat 1, the connecting wire 25 can pull the limiting portion 31 downward and compress the elastic portion 32, when the electrical box 21 drives the charging connector 23 to extend into the mounting seat 1, the limiting portion 31 can be pushed upward under the elastic force of the elastic portion 32, and the connecting wire 25 is pulled to reset to avoid the connecting wire 25 from being entangled. In other embodiments, the limiting portion 31 can also be a guide wheel, and the guide wheel is rotatably connected to the telescopic end of the elastic portion 32, so as to guide the connecting wire 25.

[0035] like Figure 1 , Figure 2 , Figures 5 to 10 As shown, the adjustment mechanism 4 includes an adjustment member 41 and a locking portion 42. The adjustment member 41 is connected to the electrical box 21. The adjustment member 41 can adjust the charging connector 23 according to the position of the charging interface on the mobile energy storage device to facilitate charging the mobile energy storage device. The locking portion 42 can lock the adjustment member 41 to prevent the charging connector 23 from shaking up and down when the charging mechanism 2 is not in use.

[0036] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10 As shown, the adjustment member 41 includes a lifting portion 411, an elastic portion 2 412, a fixing ring 413, a guide portion 414, a guide ring 415, an elastic portion 3 416, a movable structure 417, a cleaning portion 418 and a protrusion 419. A mounting port 211 is provided on the front side of the electrical box 21. The lifting portion 411 is slidably connected in the mounting port 211. The area of ​​the lifting portion 411 is larger than the area of ​​the mounting port 211, so that when the lifting portion 411 slides up and down in the mounting port 211, the mounting port 211 can still be sealed to prevent water vapor in the air from entering the electrical box 21 from the mounting port 21, thereby preventing water vapor in the air from damaging the electrical components in the electrical box 21.

[0037] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10As shown, the charging connector 23 is rotatably connected to the lifting part 411, and the lifting and lowering of the lifting part 411 can drive the charging connector 23 to move up and down. The elastic part 2 412 is connected between the lifting part 411 and the installation port 211, and the elastic part 2 412 is a spring, which is used to drive the lifting part 411 to reset. The fixing ring 413 is connected to the lifting part 411, and the charging connector 23 is located on the inner side of the fixing ring 413. The guide ring 415 is connected to the fixing ring 413. The guide part 414 and the elastic part 3 416 are both provided in two numbers. The two guide parts 414 are both slidably connected to the guide ring 415, and the guide part 414 is connected to the charging connector 23. The two elastic parts 3 416 are respectively connected between the guide part 414 and the two fixing rings 413. The elastic part 3 416 is a spring, which is used to drive the guide part 414 to reset. The elastic force of the elastic part 3 416 is much smaller than the elastic force of the elastic part 2 412.

[0038] When the electrical box 21 extends out of the mounting seat 1, the guide portion 414 first contacts the bottom of the frame of the mobile energy storage device. After the tire gas leaks, the frame tilts as a whole and the height decreases. At this time, the guide portion 414 continues to move after contacting the frame. Under the action of the elastic portion three 416, the guide portion 414 fits with the top of the frame, so that the guide portion 414 drives the charging connector 23 to rotate, thereby adapting to the charging interface on the frame. At the same time, the guide portion 414 continues to move after contacting the frame, and can drive the limiting portion 31 to move downward according to the height of the bottom of the frame, so that the limiting portion 31 drives the charging connector 23 to move downward to a position corresponding to the charging interface on the frame, so as to facilitate the subsequent connection between the charging connector 23 and the charging interface on the frame, and when the charging connector 23 moves downward, it drives the lifting portion 411 to move downward and compresses the elastic portion two 412.

[0039] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10 As shown, the guide portion 414 includes a horizontal section 4141, an inclined section 4142 and a connecting section 4143, the connecting section 4143 is connected to the charging connector 23, the connecting section 4143 is slidably connected to the guide ring 415, and the two ends of the elastic portion three 416 are respectively connected to the connecting section 4143 and the fixing ring 413, the horizontal section 4141 is connected to the connecting section 4143, the inclined section 4142 is connected to the horizontal section 4141, and the horizontal sections 4141 of the two guide portions 414 are both higher than the bottom of the frame when the tire is in a normal state.

[0040] When the guide part 414 moves, the inclined section 4142 first contacts the bottom of the frame. When the frame is tilted, because the elastic force of the elastic part three 416 is much smaller than the elastic force of the elastic part two 412, and the horizontal sections 4141 of the two guide parts 414 are higher than the bottom of the frame under the normal state of the tire, the guide part 414 is blocked by the frame and then rotates, so that the inclined section 4142 fits with the bottom of the frame, thereby driving the charging connector 23 to rotate. When the guide part 414 continues to move, the inclined section 4142 moves downward and moves the charging connector 23 downward until the horizontal section 4141 on the guide part 414 contacts the bottom of the frame. After the horizontal section 4141 contacts the bottom of the frame, the height and angle of the charging connector 23 are adjusted. At this time, the electrical box 21 continues to move so that the charging connector 23 can be plugged into the charging interface on the frame.

[0041] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10 As shown, the protrusion 419 and the cleaning portion 418 are both connected to the inclined surface where the inclined section 4142 contacts the bottom of the frame. When the inclined section 4142 moves to the bottom of the frame, the cleaning portion 418 contacts the bottom of the frame. The cleaning portion 418 is made of sponge. When the inclined section 4142 continues to move, the cleaning portion 418 and the protrusion 419 can clean the subsequent contact area between the bottom of the frame and the horizontal section 4141, so as to enhance the accuracy of adjusting the angle and height of the charging connector 23.

[0042] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10 As shown, the mobile structure 417 includes a roller 4171, a belt 4172 and a transmission roller 4173. The horizontal section 4141 is provided with a mounting cavity 4144. Two rollers 4171 are provided. The two rollers 4171 are rotatably connected to the front and rear ends of the inner side of the mounting cavity 4144 respectively. The belt 4172 is transmission-connected between the two rollers 4171. The transmission roller 4173 is rotationally connected in the mounting cavity 4144. The transmission roller 4173 is provided in plurality. The plurality of transmission rollers 4173 are connected to the belt 4172. The inner top wall contacts, and after the cleaning part 418 is separated from the bottom of the frame, the top of the belt 4172 fits tightly with the bottom of the frame. At this time, the guide part 414 continues to move, which can drive the transmission between the belt 4172 and the two rollers 4171. At the same time, the belt 4172 is supported by the transmission roller 4173 to prevent the guide part 414 from scratching the bottom of the frame. In other embodiments, the movable structure 417 is also composed of multiple rotating rollers, which contact with the bottom of the frame through multiple rotating rollers to avoid scratching the bottom of the frame.

[0043] Continue to refer Figure 1 , Figure 2 , Figures 5 to 10As shown, the locking portion 42 includes an internal threaded sleeve 421, a screw rod 422, a gear 423 and a toothed plate 424. The internal threaded sleeve 421 is rotatably connected to the electrical box 21, and the internal threaded sleeve 421 is vertically arranged. The toothed plate 424 is connected to the slide rail 11. The gear 423 is connected to the bottom end of the internal threaded sleeve 421, and the bottom end of the internal threaded sleeve 421 extends into the slide rail 11. The gear 423 is meshed and connected with the toothed plate 424. The screw rod 422 is threadedly connected to the internal threaded sleeve 421. 1, the top end of the screw rod 422 extends into the installation opening 211, and the top end of the screw rod 422 is limitedly slidably connected with the inner wall of the bottom opening of the lifting part 411, so that when the internal thread sleeve 421 rotates, the screw rod 422 will not be driven to rotate, and the top of the screw rod 422 contacts the inner top wall of the bottom opening of the lifting part 411, thereby locking the lifting part 411 to prevent the lifting part 411 from driving the charging connector 23 to shake up and down due to ground vibration when the charging mechanism 2 is not in use.

[0044] When the charging mechanism 2 is in use, the pushing member 22 pushes the electrical box 21 so that the electrical box 21 extends out of the mounting base 1. At this time, the gear 423 is meshed with the toothed plate 424 for transmission, and the gear 423 drives the internal threaded sleeve 421 to rotate so that the screw 422 moves downward. At this time, the adjusting member 41 is not in contact with the frame, thereby providing sufficient space for the subsequent downward movement of the lifting part 411.

[0045] After the charging mechanism 2 is used, the pusher 22 pulls the electrical box 21 into the mounting base 1. At this time, the gear 423 and the toothed plate 424 are meshed and transmitted, and the gear 423 drives the internal threaded sleeve 421 to rotate, so that the screw 422 moves up until the screw 422 contacts the inner top wall of the bottom opening of the lifting part 411.

[0046] Working principle: When charging is needed, the mobile energy storage device will use the sensing system to sense the position of the positioning rod 24 so that the mobile energy storage device can move to the corresponding position of the charging device. The pushing member 22 can push the electrical box 21 out of the mounting seat 1. When the electrical box 21 moves, the gear 423 engages with the toothed plate 424 for transmission, and the gear 423 drives the internal threaded sleeve 421 to rotate, so that the screw 422 moves downward. At this time, the adjusting member 41 is not in contact with the frame.

[0047] The adjusting member 41 continues to move, and the cleaning portion 418 on the guiding portion 414 contacts the bottom of the frame. When the frame is tilted, the guiding portion 414 is blocked by the frame and rotates, so that the cleaning portion 418 on the tilting section 4142 fits the bottom of the frame, thereby driving the charging connector 23 to rotate.

[0048] As the guide portion 414 continues to move, the inclined section 4142 moves downward and causes the charging connector 23 to move downward. After the cleaning portion 418 is separated from the bottom of the frame, the top of the belt 4172 fits tightly against the bottom of the frame, thereby completing the adjustment of the angle and height of the charging connector 23. At this time, the guide portion 414 continues to move, driving the transmission between the belt 4172 and the two rollers 4171, and the transmission roller 4173 supports the belt 4172 until the charging connector 23 is connected to the charging interface on the frame, thereby charging the mobile energy storage device.
