Description

Technical Field

[0001] This invention belongs to the technical field of vehicle mobile charging equipment, specifically relating to a self-moving multi-device new energy charging device and method that is advantageous for complex terrain. Background Technology

[0002] Mobile charging stations can provide emergency charging services for electric vehicles, tunnel power equipment, construction equipment, and others. Mobile charging stations are particularly valuable in dealing with sudden power shortages or in areas lacking fixed charging stations. When cars, excavators, or construction equipment run out of power and cannot be charged at nearby charging stations, mobile charging stations can proactively travel to designated areas to charge the equipment.

[0003] Chinese Patent Application No. 202511062526.7 discloses a portable, safe charging pile with energy storage, comprising a base. A horizontal adjustment mechanism is located at the top of the base, and a limit braking mechanism, a support mechanism, and a security anti-theft mechanism are located at the bottom of the base. The horizontal adjustment mechanism includes side plates symmetrically fixedly connected to the top of the base. A first upright block is fixedly connected to one side of each side plate. A first rotating shaft rotatably passes through each of the two first upright blocks. A first winding drum is fixedly connected to the outer wall of the first rotating shaft. A steel wire rope A is wound around the first winding drum, and the other end of the steel wire rope A is fixedly connected to the charging pile body. This invention ensures the charging pile remains level even on inclined ground, preventing the fixing bolts of the battery pack inside the charging pile from breaking and slipping, ensuring safe use, and ensuring uniform distribution of electrolyte and pressure inside the battery pack, preventing the sealing ring from rupturing.

[0004] In some emergency charging processes, it may be necessary to enter construction tunnels or irregular road sections where frequent vibrations occur. If the charging power supply equipment is subjected to severe vibrations, it may be damaged. At the same time, the power requirements of multiple devices requiring rescue are different. If each charging power supply of different models and sizes is equipped with a mobile device, the cost will be high. If a single mobile device is used and the charging power supply is replaced by disassembly, the probability of the power supply falling and being damaged is increased if it is not stable and tilted. On the other hand, a stable structure to increase stability requires complicated replacement and installation when replacing charging power supply of different models and sizes, which is difficult to achieve simultaneously. At the same time, how to quickly install and replace power supply equipment of different sizes and how to protect it have become research priorities. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a self-moving multi-device new energy charging device and method that is suitable for complex terrain. Through the cooperation of a first side buffer mechanism, a second side buffer mechanism, and a bottom buffer mechanism, this invention enables the remote-controlled mobile chassis to quickly position and assemble charging power devices of different sizes on complex terrain without requiring device replacement, while also providing all-around cushioning to prevent them from falling off. Furthermore, the invention utilizes a combination of limiting mechanisms and a top cover to facilitate the rapid connection of the four limiting mechanisms, and is applicable to the installation of charging power devices of different sizes, while simultaneously protecting the top of the charging power devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A self-propelled multi-device new energy charging device suitable for complex terrain includes a remote-controlled mobile chassis. A housing is fixedly connected to the top of the remote-controlled mobile chassis. A bottom buffer mechanism is installed at the bottom of the housing. A first side buffer mechanism and a second side buffer mechanism are installed at intervals on the four side walls of the housing. The first side buffer mechanism and the second side buffer mechanism are located above the bottom buffer mechanism. A charging power supply device abuts between the bottom buffer mechanism, the first side buffer mechanism, and the second side buffer mechanism.

[0007] Furthermore, the first side buffer mechanism includes a first buffer plate, which is fixedly connected to the inner wall of the receiving box by a plurality of first buffer springs; a first plug-in block is fixedly provided at equal distances at both ends of the first buffer plate, and a first adjustment groove is provided through the top of the first plug-in block; the second side buffer mechanism includes a second buffer plate, which is fixedly connected to the inner wall of the receiving box by a plurality of second buffer springs; a second plug-in block is fixedly provided at equal distances at both ends of the second buffer plate, and a second adjustment groove is provided through the top of the second plug-in block.

[0008] Furthermore, the first plug-in block and the adjacent second plug-in block are arranged crosswise; the first adjustment slot and the adjacent second adjustment slot are jointly provided with a limiting mechanism; the limiting mechanism includes a connecting plate, a plug-in rod is fixedly provided in the middle of the bottom of the connecting plate, and limiting rods are fixedly provided on both sides of the bottom of the connecting plate, the limiting rods respectively abutting against the first plug-in block and the adjacent second plug-in block.

[0009] Furthermore, the bottom buffer mechanism includes a bottom buffer plate, the bottom of which is fixedly connected to the inner bottom of the receiving box by a plurality of bottom buffer springs; the bottom buffer plate is slidably connected to the inside of the receiving box; when the bottom buffer plate is not under force, the bottoms of the first side buffer mechanism and the second side buffer mechanism abut against the bottom buffer plate.

[0010] Furthermore, an adjusting rod is fixedly connected to the top center of the connecting plate, and the adjusting rods of the four limiting mechanisms are rotatably connected to the top cover.

[0011] Furthermore, the top cover includes a top cover body, with a rotating shaft fixedly connected to the bottom center of the top cover body. The rotating shaft is rotatably connected to one end of the telescopic tube; the other end of the telescopic tube is rotatably connected to the top of the adjusting rod.

[0012] Furthermore, two first limiting blocks are fixedly connected to the rotating shaft; the rotating shaft located between the two first limiting blocks is rotatably connected to the rotating hole at one end of the telescopic tube; the rotating holes of the four telescopic tubes are all located between the two first limiting blocks.

[0013] Furthermore, two second limiting blocks are fixedly connected to the top of the adjusting rod, and the rotating hole of the telescopic tube is rotatably connected to the adjusting rod between the two second limiting blocks.

[0014] Furthermore, all four limiting mechanisms are the same size.

[0015] This invention also claims a method for using the aforementioned self-moving multi-device new energy charging device that is advantageous for complex terrain, comprising the following steps: S1. Pull open the first and second buffer plates, place the charging power devices of different sizes on top of the bottom buffer mechanism, and then release to allow the first and second buffer plates to automatically abut against the charging power devices. S2. Insert the plug rod of the limiting mechanism into the intersection center of the first adjusting groove and the adjacent second adjusting groove, and make the limiting rod abut against the first plug block and the adjacent second plug block respectively; S3. When inserting, first rotate the lowest limiting mechanism at the bottom of the top cover body to the correct angle for insertion, then rotate and insert the top cover body in sequence from low to high according to the height of the bottom of the limiting mechanism, and then press down the top cover body to complete the insertion operation. S4. When it is necessary to replace the charging power equipment of different sizes, simply pull out all the limit mechanisms.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) Through the cooperation of the first side buffer mechanism, the second side buffer mechanism and the bottom buffer mechanism, the present invention enables the remote-controlled mobile chassis to quickly position and assemble charging power devices of different sizes when moving on complex terrain without changing the equipment, and also provides an all-round buffering effect without falling off; specifically, by installing the first side buffer mechanism and the second side buffer mechanism at intervals on the four side walls of the housing, and by setting the first plug-in block and the adjacent second plug-in block crosswise, the first buffer plate and the second buffer plate can be laterally positioned separately. While moving, it can also abut against charging power devices, thus making it suitable for charging power devices of different sizes. Installation simply requires pulling apart the first and second buffer plates and inserting the device. After placing the charging power device between the first and second buffer plates, simply insert the plug-in rod of the limiting mechanism into the intersection center of the first adjustment slot and the adjacent second adjustment slot, and make the limiting rod abut against the first plug-in block and the adjacent second plug-in block respectively for quick positioning of the charging power device. It does not need to be fixed in place. Due to the three-bar structure design of the limiting mechanism, the plug-in rod always connects the first plug-in block and the adjacent second plug-in block. The two limiting rods interact with each other. If the charging power supply device is vibrated and undergoes lateral displacement, one of the limiting rods will be quickly pushed forward. Under the action of the plug-in rod, the other limiting rod will be pressed more tightly. Thus, by simply plugging in the limiting mechanism, charging power supply devices of different sizes can be quickly positioned and assembled. The operation is simple and does not require equipment replacement. At the same time, due to the aforementioned limiting mechanism, the first and second buffer plates can form a whole with the charging power supply device. After the charging power supply device is installed, it will be cushioned horizontally without any blind spots by the first and second buffer springs around it. Since the first and second side buffer mechanisms are located above the bottom buffer mechanism, the charging power supply device only needs to be placed on the bottom buffer mechanism for vertical cushioning without positioning. During cushioning, under the aforementioned limiting action of the limiting mechanism, the first and second buffer plates always tightly abut against the charging power supply device. Even if it tipps over, the positioned charging power supply device will not fall and be damaged. Thus, while quickly replacing charging power supply devices of different sizes, the safety of the charging power supply device is also guaranteed.

[0017] (2) This invention, through the structural cooperation of the limiting mechanism and the top cover, not only assists in the rapid insertion of the four limiting mechanisms, but also applies to the installation of charging power supply devices of different sizes, and can simultaneously protect the top of the charging power supply device; specifically, since the rotating holes of the four telescopic tubes are all located between the two first limiting blocks, the four limiting mechanisms have a high-low sequence. Therefore, during insertion, it is not necessary to insert all the limiting mechanisms simultaneously to avoid jamming. The lowest limiting mechanism at the bottom of the top cover body can be rotated to the correct angle before insertion, and then... Then, according to the height of the bottom of the limiting mechanism, rotate and insert it sequentially from low to high. Then, press down the top cover body to complete the insertion operation. This helps to quickly insert the four limiting mechanisms. At the same time, since the telescopic tube is telescopic, and one end of the telescopic tube is rotatably connected to the rotating shaft, and the other end is rotatably connected to the adjusting rod of the limiting mechanism, it can ensure that the limiting mechanism can be smoothly inserted into any position. Therefore, it is suitable for the installation of charging power equipment of different sizes. After insertion, the top cover can protect the top of the charging power equipment and block external threats such as rain or gravel. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. Of course, the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0022] Example like Figures 1-9 As shown, a self-propelled multi-device new energy charging device suitable for complex terrain includes a remote-controlled mobile chassis 200. A housing box 100 is fixedly connected to the top of the remote-controlled mobile chassis 200. A bottom buffer mechanism 700 is installed at the bottom of the housing box 100. A first side buffer mechanism 500 and a second side buffer mechanism 600 are installed at intervals on the four side walls of the housing box 100. The first side buffer mechanism 500 and the second side buffer mechanism 600 are located above the bottom buffer mechanism 700. A charging power supply device 400 abuts between the bottom buffer mechanism 700, the first side buffer mechanism 500, and the second side buffer mechanism 600.

[0023] The present invention, through the cooperation of the first side buffer mechanism 500, the second side buffer mechanism 600 and the bottom buffer mechanism 700, enables the remote-controlled mobile chassis 200 to quickly position and assemble charging power devices 400 of different sizes when moving on complex terrain, without the need to replace the equipment, and also provides an all-round buffering effect and prevents it from falling off; a detailed description will follow.

[0024] It is worth noting that the remote-controlled mobile chassis 200 of this invention is a mature existing technology, which can move itself to move the charging power supply device 400 to a designated position, and will not be described in detail here; at the same time, the charging power supply device 400 is also a product that can be sold on the market, and the models are all different, and will not be further limited here.

[0025] Furthermore, the first side buffer mechanism 500 includes a first buffer plate 510, which is fixedly connected to the inner wall of the receiving box 100 by a plurality of first buffer springs 540; a first insertion block 520 is fixedly provided at equal intervals at both ends of the first buffer plate 510, and a first adjustment groove 530 is provided through the top of the first insertion block 520; the second side buffer mechanism 600 includes a second buffer plate 610, which is fixedly connected to the inner wall of the receiving box 100 by a plurality of second buffer springs 640; a second insertion block 620 is fixedly provided at equal intervals at both ends of the second buffer plate 610, and a second adjustment groove 630 is provided through the top of the second insertion block 620.

[0026] It is worth emphasizing that the accompanying drawings in this specification are only schematic diagrams and do not limit the specific dimensions. Adjustments can be made according to the actual charging power supply device 400 model and dimensions, which will not be described in detail here.

[0027] Furthermore, the first plug-in block 520 and the adjacent second plug-in block 620 are arranged crosswise; the first adjustment groove 530 and the adjacent second adjustment groove 630 are jointly provided with a limiting mechanism 300; the limiting mechanism 300 includes a connecting plate 310, a plug-in rod 320 is fixedly provided in the middle of the bottom of the connecting plate 310, and limiting rods 330 are fixedly provided on both sides of the bottom of the connecting plate 310, and the limiting rods 330 abut against the first plug-in block 520 and the adjacent second plug-in block 620 respectively.

[0028] This invention, through a structural design in which a first side buffer mechanism 500 and a second side buffer mechanism 600 are installed at intervals on the four side walls of the housing 100, and the first insertion block 520 is intersected with the adjacent second insertion block 620, allows the first buffer plate 510 and the second buffer plate 610 to move laterally independently while simultaneously abutting against the charging power supply device 400. This design makes it suitable for charging power supply devices 400 of different sizes. Installation simply requires pulling apart the first buffer plate 510 and the second buffer plate 610 and placing them inside. Furthermore, when the charging power supply device 400 is placed inside the first buffer plate 510 and the second buffer plate 610... After 10 seconds, simply insert the plug rod 320 of the limiting mechanism 300 into the intersection center of the first adjusting slot 530 and the adjacent second adjusting slot 630, and make the limiting rod 330 abut against the first plug block 520 and the adjacent second plug block 620 respectively. The charging power device 400 does not need to be fixed. Due to the three-bar structure design of the limiting mechanism 300, the plug rod 320 always connects the first plug block 520 and the adjacent second plug block 620 together. The two limiting rods 330 interact with each other. If the charging power device 400 is vibrated and undergoes lateral displacement, it will quickly push one of the limiting rods 330. Under the action of the plug-in rod 320, the other limiting rod 330 will abut more tightly, thus only the plug-in limiting mechanism 300 is needed to quickly position and assemble charging power devices 400 of different sizes, which is simple to operate and does not require equipment replacement; at the same time, due to the above-mentioned limiting of the limiting mechanism 300, the first buffer plate 510 and the second buffer plate 610 can form a whole with the charging power device 400. Therefore, after the charging power device 400 is installed, it will be subjected to the action of the first buffer spring 540 and the second buffer spring 640 around it, which can provide buffering without dead angles in the horizontal direction; and by The first side buffer mechanism 500 and the second side buffer mechanism 600 are located above the bottom buffer mechanism 700. Therefore, the charging power supply device 400 can be placed on the bottom buffer mechanism 700 without positioning to perform vertical buffering. During buffering, under the limiting action of the limiting mechanism 300, the first buffer plate 510 and the second buffer plate 610 are always tightly abutting against the charging power supply device 400. Even if it is overturned, the positioning charging power supply device 400 will not fall and be damaged. Thus, while being able to quickly replace charging power supply devices 400 of different sizes, the safety of the charging power supply device 400 can also be guaranteed.

[0029] Furthermore, the bottom buffer mechanism 700 includes a bottom buffer plate 710, the bottom of which is fixedly connected to the inner bottom of the receiving box 100 via a plurality of bottom buffer springs 720; the bottom buffer plate 710 is slidably connected to the inside of the receiving box 100; when the bottom buffer plate 710 is not under force, the bottoms of the first side buffer mechanism 500 and the second side buffer mechanism 600 abut against the bottom buffer plate 710.

[0030] Furthermore, an adjusting rod 340 is fixedly connected to the top center of the connecting plate 310, and the adjusting rods 340 of the four limiting mechanisms 300 are rotatably connected to the top cover 800.

[0031] The present invention, through the structural cooperation of the limiting mechanism 300 and the top cover 800, can not only assist in the quick insertion of the four limiting mechanisms 300, but also be applicable to the installation of charging power devices 400 of different sizes, and can simultaneously protect the top of the charging power device 400; a detailed description will follow.

[0032] Furthermore, the top cover 800 includes a top cover body 810, and a rotating shaft 820 is fixedly connected to the bottom center of the top cover body 810. The rotating shaft 820 is rotatably connected to one end of the telescopic tube 350; the other end of the telescopic tube 350 is rotatably connected to the top of the adjusting rod 340.

[0033] Furthermore, two first limiting blocks 821 are fixedly connected to the rotating shaft 820; the rotating shaft 820 located between the two first limiting blocks 821 is rotatably connected to the rotating hole 351 at one end of the telescopic tube 350; the rotating holes 351 of the four telescopic tubes 350 are all located between the two first limiting blocks 821.

[0034] Since the rotating holes 351 of the four telescopic tubes 350 are all located between the two first limiting blocks 821, the four limiting mechanisms 300 have a height-to-height sequence. Therefore, during insertion, it is not necessary to simultaneously insert all the limiting mechanisms 300 to avoid jamming. The lowest limiting mechanism 300 at the bottom of the top cover body 810 can be rotated to the correct angle for insertion first. Then, the limiting mechanisms 300 are rotated and inserted sequentially from low to high according to their bottom height. Finally, the entire top cover body 810 is pressed down to complete the insertion operation. This achieves auxiliary... It facilitates the quick insertion of the four limiting mechanisms 300; at the same time, since the telescopic tube 350 is telescopic, and one end of the telescopic tube 350 is rotatably connected to the rotating shaft 820, and the other end is rotatably connected to the adjusting rod 340 of the limiting mechanism 300, it can ensure that the limiting mechanism 300 can be smoothly inserted into any position, thus making it suitable for the installation of charging power equipment 400 of different sizes. After insertion, the top cover 800 can protect the top of the charging power equipment 400, blocking external threats such as rain or gravel.

[0035] Furthermore, two second limiting blocks 341 are fixedly connected to the top of the adjusting rod 340, and the rotating hole 351 of the telescopic tube 350 is rotatably connected to the adjusting rod 340 between the two second limiting blocks 341.

[0036] It is worth noting that the telescopic tube 350 is a mature existing technology, which can be an internal and external telescopic sleeve structure that passively expands and contracts through external force. It will not be described in detail here.

[0037] Furthermore, the four limiting mechanisms 300 are all the same size.

[0038] It is worth noting that since the four limiting mechanisms 300 are the same size, and the telescopic tubes 350 on the rotating shaft 820 are stacked vertically, the lower heights of the four limiting mechanisms 300 are different, thus enabling sequential insertion.

[0039] A method for using the aforementioned self-mobile multi-device new energy charging device that is advantageous for complex terrain includes the following steps: S1. Pull open the first buffer plate 510 and the second buffer plate 610, and place the charging power device 400 of different sizes on the top of the bottom buffer mechanism 700, and then release it so that the first buffer plate 510 and the second buffer plate 610 automatically abut against the charging power device 400. S2. Insert the plug rod 320 of the limiting mechanism 300 into the intersection center of the first adjustment groove 530 and the adjacent second adjustment groove 630, and make the limiting rod 330 abut against the first plug block 520 and the adjacent second plug block 620 respectively. S3. When inserting, first rotate one end of the lowest limiting mechanism 300 at the bottom of the top cover body 810 to the correct angle for insertion, then rotate and insert the top cover body 810 sequentially from low to high according to the height of the bottom end of the limiting mechanism 300, and then press down the top cover body 810 as a whole to complete the insertion operation. S4. When it is necessary to replace the charging power device 400 with a different size, simply pull out all the limit mechanisms 300.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
