Description

Technical Field

[0001] This application relates to the field of intelligent charging equipment technology, and more specifically, to a global mobile intelligent charging device. Background Technology

[0002] In the field of new energy vehicle charging facilities, conventional charging piles mostly adopt a fixed installation mode. In actual operation scenarios, such charging piles are often occupied by non-charging vehicles, resulting in idle charging resources and reduced facility utilization efficiency.

[0003] At the same time, although mobile charging devices have been applied in existing technologies, most devices are bulky and take up a lot of space, which not only makes it difficult to carry out centralized charging management, but also hinders their large-scale deployment and efficient operation and maintenance. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a fully mobile intelligent charging device, including a fixed truss, on which a power supply box is electrically connected. Multiple charging sliders are slidably connected to the upper limit of the fixed truss, and each charging slider is electrically connected to the power supply box. A mobile charging box is detachably and electrically connected to each charging slider. The mobile charging box has a built-in battery and possesses dual functions of direct AC charging and battery charging. The mobile charging box includes a mobile body, on which a charging gun is electrically connected to the side wall. An electric push rod and a buffer assembly are provided at the bottom of the mobile body. The electric push rod extends through its piston end, causing the bottom of the buffer assembly to descend. The bottom of the impact assembly is equipped with tracked omnidirectional wheels. The height of the moving box can be changed by the extension and retraction of the piston end of the electric push rod. The back of the moving box is electrically connected to a charging assembly, which is detachably electrically connected to the charging slider. When the moving charging box is connected to the charging slider, it can directly charge the vehicle with AC power or charge the built-in battery. At this time, the piston end of the electric push rod retracts, and the moving box is attached to the charging slider. When the moving charging box and the charging slider are separated, the vehicle will be charged through the built-in battery. At this time, the tracked omnidirectional wheels are powered by the battery and drive the moving box to move.

[0005] Preferably, a movable compartment is provided on one side of the fixed truss along its own length, and multiple charging sliders are limited to slide within the movable compartment.

[0006] Preferably, one end of the charging slider extends out of the mobile compartment, and the end is provided with a charging groove. The charging groove is L-shaped, and a conductive strip is fixed inside the charging groove. The upper surface of the end of the charging slider extending out of the mobile compartment is provided with multiple end face positioning holes.

[0007] Preferably, at least two electric push rods are provided, and the two electric push rods are symmetrically arranged on both sides of the bottom end of the mobile housing, and are electrically connected to the battery built into the mobile housing.

[0008] Preferably, the buffer assembly includes a connecting column fixed to the middle of the bottom end of the movable box, a top plate fixed to the bottom end of the connecting column, the top plate being located between the two electric push rods and not in contact with the electric push rods, two sets of elastic members being symmetrically fixed to the bottom side of the top plate, and a bottom plate being elastically slidably sleeved on the two sets of elastic members, the bottom plate being located on the bottom side of the two electric push rods.

[0009] Preferably, the elastic element includes a hydraulic damping cylinder fixed to the top plate, a spring is sleeved on the hydraulic damping cylinder, the top end of the spring is fixed to the top plate, a limit plate is fixed to the bottom end of the spring, the limit plate is slidably sleeved on the hydraulic damping cylinder, a limit rod is coaxially fixed to the bottom end of the hydraulic damping cylinder, and the bottom plate is slidably sleeved on the limit rod and fixedly connected to the limit plate.

[0010] Preferably, after the piston end of the electric push rod retracts, its piston end does not contact the base plate; when the piston end of the electric push rod extends, its piston end abuts against the base plate and pushes the base plate to move downward along the limiting rod, during which the spring is stretched.

[0011] Preferably, the charging assembly includes an L-shaped back plate fixed to the back of the mobile housing, and the L-shaped back plate has a second conductive strip that is electrically connected to the electrical components inside the mobile housing. The second conductive strip and the first conductive strip are detachably electrically connected.

[0012] Preferably, the conductive strip has symmetrically arranged side positioning blocks fixed to the L-shaped back plate on both sides. The side positioning blocks are L-shaped and are slidably inserted into the charging slot and form a snap-fit ​​with the charging slot. The side positioning blocks can be displaced along the height direction within the charging slot.

[0013] Preferably, a plurality of upper positioning posts are fixedly connected to the bottom end of the transverse section of the L-shaped back plate, and the upper positioning posts are respectively inserted into the plurality of end face positioning holes.

[0014] The beneficial effects of this invention are:

[0015] 1. By utilizing the detachable electrical connection between the mobile box and the charging slider, the vehicle can be directly charged by mains power when the two are connected. When the two are separated, the mobile box can be moved next to the vehicle to charge the vehicle using the built-in battery, achieving a convenient charging effect and reducing space occupation.

[0016] 2. By utilizing the limiting sliding of the charging slider on the fixed truss, the charging slider can slide a certain distance on the fixed truss, changing its own position and avoiding its original position being occupied by vehicles, which would prevent the mobile box from being blocked and unable to be charged directly, or from being unable to leave the fixed truss or return to the fixed truss, thus improving the convenience of use.

[0017] 3. By utilizing the extension and retraction of the flashlight push rod, the height of the movable box relative to the ground can be changed, facilitating electrical connection or disconnection between it and the charging slider. After the two are connected, the tracked omnidirectional wheel leaves the ground, thereby locking the movable box and the charging slider to prevent them from suddenly separating.

[0018] 4. The use of tracked omnidirectional wheels can improve the mobility of the mobile charging unit, making it suitable for different terrains or ground conditions and enhancing the overall practicality of the charging equipment.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Example 1, as Figures 1-6 As shown, a fully mobile intelligent charging device according to an embodiment of this application includes a fixed truss 1, a power supply box 2 electrically connected to the fixed truss 1, and a plurality of charging sliders 3 slidably connected to the upper limit of the fixed truss 1. The plurality of charging sliders 3 are all electrically connected to the power supply box 2, and a mobile charging box 4 is detachably electrically connected to the charging slider 3. It can be understood that in this application, the fixed truss 1 can be used to centrally manage the charging of the plurality of mobile charging boxes 4, so as to avoid the mobile charging boxes 4 being parked randomly, or even damaged or lost after use.

[0036] In a specific embodiment of this application, the mobile charging box 4 has a built-in battery and has dual functions of direct AC charging and battery charging. When the mobile charging box 4 is on the fixed truss 1 and the space in front of it is not occupied by vehicles or other obstacles, the vehicle can be driven directly to this location for direct AC charging. If the space in front of it is occupied and the vehicle cannot drive in, and the mobile charging box 4 cannot form an effective connection with the vehicle, then the mobile charging box 4 can be removed from the fixed truss 1 and moved to the vicinity of the vehicle to charge the vehicle using the battery inside the mobile charging box 4, thereby improving the practicality and convenience of the charging device of this application.

[0037] The mobile charging box 4 includes a mobile box body 41, a charging gun electrically connected to the side wall of the mobile box body 41, an electric push rod 42 and a buffer assembly 43 at the bottom of the mobile box body 41, the electric push rod 42 can lower the bottom of the buffer assembly 43 by extending its piston end, a tracked omnidirectional wheel 44 is provided on the bottom side of the buffer assembly 43, the tracked omnidirectional wheel 44 can realize the height change of the mobile box body 41 by the extension and retraction of the piston end of the electric push rod 42, and a charging assembly 45 is electrically connected to the back side of the mobile box body 41, the charging assembly 45 and the charging slider 3 are detachably electrically connected.

[0038] Understandably, when the mobile charging box 4 is connected to the charging slider 3, it can directly charge the vehicle with AC power or charge the built-in battery. At this time, the piston end of the electric push rod 42 retracts, and the mobile box 41 is hung on the charging slider 3. When the mobile charging box 4 and the charging slider 3 are separated, the vehicle will be charged through the built-in battery. At this time, the tracked omnidirectional wheel 44 is powered by the battery to drive the mobile box 41 to move.

[0039] like Figure 1 As shown, a movable cabin 11 is provided on one side of the fixed truss 1 along its own length, and multiple charging sliders 3 are limited to slide in the movable cabin 11.

[0040] It should be noted that the charging slider 3 and the power supply box 2 can be electrically connected via a power cable. The length of the power cable allows the charging slider 3 to move within a certain range in the moving compartment 11, which facilitates changing the position of the charging slider 3 on the fixed truss 1 within the range of its travel, giving it a certain degree of flexibility and avoiding a fixed setting.

[0041] like Figure 5 and Figure 6 As shown, one end of the charging slider 3 extends out of the movable compartment 11, and a charging groove 31 is provided at this end. The charging groove 31 is L-shaped, and a conductive strip 32 is fixedly connected inside the charging groove 31. Multiple end face positioning holes 33 are provided on the upper end face of the end of the charging slider 3 extending out of the movable compartment 11.

[0042] It should be noted that, in the specific embodiments of this application, the conductive strip 32 and the charging slider 3 are electrically connected, and the charging slider 3 is disposed facing the inside of the charging slot 31 to avoid exposure and reduce the risk of electric shock caused by accidental contact by personnel. At the same time, it also avoids contamination on it to a certain extent, which would affect its conductivity in subsequent use.

[0043] like Figure 3 As shown, at least two electric push rods 42 are provided. The two electric push rods 42 are symmetrically arranged on both sides of the bottom end of the movable housing 41 and are electrically connected to the battery built into the movable housing 41.

[0044] like Figure 3 and Figure 4 As shown, the buffer assembly 43 includes a connecting column 431 fixed to the middle of the bottom end of the movable housing 41. A top plate 432 is fixed to the bottom end of the connecting column 431. The top plate 432 is located between the two electric push rods 42 and does not contact the electric push rods 42. Two sets of elastic members are symmetrically fixed to the bottom side of the top plate 432. A bottom plate 437 is elastically slidably sleeved on the two sets of elastic members. The bottom plate 437 is located on the bottom side of the two electric push rods 42.

[0045] Furthermore, the elastic element includes a hydraulic damping cylinder 433 fixed to the top plate 432, a spring 434 sleeved on the hydraulic damping cylinder 433, the top end of the spring 434 fixed to the top plate 432, a limit plate 435 fixed to the bottom end of the spring 434, the limit plate 435 slidably sleeved on the hydraulic damping cylinder 433, a limit rod 436 coaxially fixed to the bottom end of the hydraulic damping cylinder 433, and a bottom plate 437 slidably sleeved on the limit rod 436 and fixedly connected to the limit plate 435.

[0046] Understandably, when the piston end of the electric push rod 42 retracts, its piston end does not contact the base plate 437; when the piston end of the electric push rod 42 extends, its piston end abuts against the base plate 437 and pushes the base plate 437 downward along the limit rod 436. During this process, the spring 434 is stretched. Since the tracked omnidirectional wheel 44 below is always in contact with the ground, the electric push rod 42 will push the entire moving box 41 upward in the opposite direction, changing the height of the moving box 41.

[0047] like Figure 5 and Figure 6 As shown, the charging assembly 45 includes an L-shaped back plate 451 fixed to the back of the movable housing 41. The L-shaped back plate 451 has a conductive strip 452 that is electrically connected to the electrical components inside the movable housing 41. The conductive strip 452 and the conductive strip 32 are detachably electrically connected.

[0048] Specifically, conductive metal is provided on the outer sides of conductive strip 452 and conductive strip 32 respectively, so that they can be electrically connected when they come into contact.

[0049] Furthermore, the conductive strip 452 is symmetrically provided with side positioning blocks 453 fixed to the L-shaped back plate 451 on both sides. The side positioning blocks 453 are L-shaped and are slidably inserted into the charging slot 31 and form a snap-fit ​​with the charging slot 31. The side positioning blocks 453 can be displaced along the height direction within the charging slot 31.

[0050] Furthermore, multiple upper positioning posts 454 are fixed to the bottom of the horizontal section of the L-shaped back plate 451, and the upper positioning posts 454 are respectively inserted into multiple end face positioning holes 33.

[0051] Thus, it is understandable that when there is space in front of the fixed truss 1 to park a vehicle that needs charging, the vehicle can drive in directly. At this time, the mobile box 41 is connected to the charging slider 3 via the charging component 45 and forms an electrical connection with the charging slider 3. The user can then directly remove the charging gun on the side wall of the mobile box 41 to charge the vehicle. The power source is the mains power connected to the power supply box 2. Of course, the charging slider 3 has a certain sliding range on the fixed truss 1, which also gives the mobile box 41 a certain displacement range on the fixed truss 1, improving the flexibility of use. When the mobile housing 41 is not charging the vehicle, it can charge its internal battery through the electrical connection between itself and the charging slider 3 for later use. When there is no space to park the vehicle in front of the fixed truss 1, the vehicle needs to be charged. In this case, the mobile housing 41 needs to be removed from the fixed truss 1, that is, the electrical connection between the charging component 45 and the charging slider 3 needs to be disconnected. At this time, the piston end of the electric push rod 42 can extend and abut against the bottom plate 437. Because the tracked omnidirectional wheel 44 is always in contact with the ground, the bottom plate 437 cannot move downwards, thus reversing the movement of the vehicle. This causes the fixed end of the electric push rod 42 and the moving housing 41 to move upwards. Understandably, the conductive strip 452, which was originally electrically connected within the charging slot 31, will move upwards and detach from the conductive strip 32. During this process, the limiting rod 436 disengages from the corresponding end-face positioning hole 33 until the bottom end of the side positioning block 453 is higher than the bottom end of the notch in the charging slot 31. Then, the tracked omnidirectional wheel 44 drives the moving housing 41 to move outwards, completely detaching the side positioning block 453 from the charging slot 31, thus breaking the electrical connection between the moving housing 41 and the charging slider 3. Then, through... The tracked omnidirectional wheel 44 allows the mobile housing 41 to move next to the vehicle. At this point, the charging gun on the mobile housing 41 can be plugged into the vehicle's charging port to charge the vehicle using the stored energy. After charging is complete, the mobile housing 41 is moved back to the fixed truss 1, and the side positioning block 453 is plugged back into the charging slot 31. The piston end of the electric push rod 42 retracts, allowing the conductive strip 452 and the conductive strip 32 to re-establish an electrical connection. It should be noted that the tracked omnidirectional wheel 44 in this application is prior art, which is adaptable to various terrains and improves the mobility of the charging equipment in this application.

[0052] It should be noted that, in the specific embodiments of this application, the all-domain mobile intelligent charging device of this application can be equipped with an intelligent management system, which supports self-diagnosis, remote monitoring and intelligent scheduling, and real-time viewing of key parameters such as charging power, current, voltage and fault warning information. It has multiple safety protections, such as overvoltage, overcurrent, undervoltage, ESD, lightning protection, overcharging, overload, fire, overheating, waterproofing, leakage and chip protection. The all-domain mobile intelligent charging device of this application can be applied to many scenarios such as highway service areas, residential areas and community parking lots, commercial complexes and scenic area parking lots, emergency rescue, industrial parks and logistics parks, outdoor activities and tourism. The intelligent control system configured therein will not be described in detail here.

[0053] In related technologies, this kind of all-domain mobile intelligent charging device, due to the different terrains, the mobile box 41 will inevitably encounter uneven ground during the movement. Although the tracked omnidirectional wheels 44 have strong passability, the mobile box 41 is equipped with many electrical components such as batteries, and it has a certain weight. Once the mobile box 41 tilts at a large angle during the movement, it will cause the entire mobile charging box 4 to be unstable and even fall to the ground, seriously affecting its use and even causing damage to the mobile charging box 4.

[0054] Example 2, according to some embodiments of this application, such as Figures 1-3 , Figure 7 and Figure 8 As shown, a balancing mechanism 5 is provided between the buffer assembly 43 and the tracked omnidirectional wheel 44. The balancing mechanism 5 includes an axle positioning assembly 51 with its two ends fixed to the bottom end of the buffer assembly 43 and the top end of the tracked omnidirectional wheel 44, respectively, and a plurality of circumferential correction assemblies 52 arranged around the axle positioning assembly 51. The two ends of the apex of the plurality of circumferential correction assemblies 52 are also fixed to the bottom end of the buffer assembly 43 and the top end of the tracked omnidirectional wheel 44, respectively. The plurality of circumferential correction assemblies 52 are electrically connected to the battery and have independent extension and retraction capabilities.

[0055] Specifically, the axial positioning assembly 51 includes a support rod 511 in the middle and two spherical hinge seats 512 at both ends, with the spherical hinge seats 512 and the support rod 511 spherically hinged.

[0056] Specifically, the circumferential correction component 52 includes an inclined electric push rod 521, with a U-shaped frame 522 hinged to the top and bottom ends of the electric push rod 521, and a fixed seat 523 rotatably connected to the U-shaped frame 522.

[0057] Furthermore, the rotational directions between the electric push rod 521 and the convex frame 522, and between the convex frame 522 and the fixed base 523, are respectively in two perpendicular planes.

[0058] Therefore, it can be understood that although the support rod 511 forms spherical hinges with the bottom end of the buffer assembly 43 (i.e., the base plate 437) and the top end of the tracked omnidirectional wheel 44 through the spherical hinge seats 512 at both ends, making it have no supporting capacity when used alone, it can provide a certain supporting strength when used in conjunction with multiple circumferential correction components 52, when the moving box 41, support rod 511, and tracked omnidirectional wheel 44 are all kept vertical and coaxial, reducing the pressure on the circumferential correction components 52. The peripheral correction component 52 can ensure that the mobile box 41 remains vertical regardless of the terrain encountered by the tracked omnidirectional wheel 44, and when the top of the tracked omnidirectional wheel 44 is tilted (of course, this angle is within a certain range). It can also adjust the center of gravity position above the tracked omnidirectional wheel 44 to prevent the entire mobile charging box 4 from becoming unbalanced and falling over.

[0059] In related technologies, this kind of all-domain mobile intelligent charging device has the functions of separating from and returning to its original position on the fixed truss 1, and after returning to its original position, it can charge the battery and the vehicle. Therefore, the conductive strip 452 on the mobile box 41 and the conductive strip 32 on the charging slider 3 need to have good contact in order to achieve the conductive effect between the two.

[0060] Example 3, according to some embodiments of this application, such as Figures 9-11 As shown, a protective mechanism 6 is provided on the side positioning block 453. The protective mechanism 6 includes a collision plate 61 that is elastically inserted into the side of the side positioning block 453 facing the charging slot 31, and a centering block 62 that is fixed to the collision plate 61 and located on the side of the side positioning block 453 away from the conductive strip 452.

[0061] The charging slot 31 has two symmetrical beveled sections 311 at its two corners; the side positioning block 453 has a sliding cavity 455 on the side facing the charging slot 31.

[0062] Specifically, at least two guide posts 611 are fixedly connected to the anti-collision plate 61. The two guide posts 611 are slidably inserted into the sliding cavity 455, and the ends of the guide posts 611 are coaxially fixedly connected to the limiting rings 612. The limiting rings 612 limit the sliding within the sliding cavity 455, and a spring 613 abuts between the limiting rings 612 and the inner end of the sliding cavity 455.

[0063] Furthermore, a second inclined surface 621 is provided on the side of the middle block 62, and the second inclined surface 621 and the first inclined surface 311 fit together.

[0064] Therefore, it can be understood that when the moving housing 41 returns to its original position and the charging component 45 is inserted into the charging slot 31, the inclined surfaces 621 of the two centering blocks 62 on both sides come into contact with the notch of the charging slot 31 and form a lateral displacement, so that the charging slot 31 and the charging component 45 can form a centering action, preventing the side positioning block 453 from directly impacting the charging slider 3. Secondly, after the centering action is formed, during the process of the side positioning block 453 moving into the charging slot 31, the anti-collision plate 61 will first abut against the inner side wall of the charging slot 31, and during the continuous displacement, it will force the limiting ring 612 to compress the spring 613. By utilizing the elasticity of the spring 613, the rigid collision formed during the insertion process is transformed into a flexible collision, reducing the vibration formed by the insertion of the charging slider 3 and the charging component 45, reducing the probability of damage, and improving the service life of the entire charging equipment.

[0065] It should be noted that the specific models and specifications of the power supply box 2, electric push rod 42, tracked omnidirectional wheel 44, hydraulic damping cylinder 433, spring 434, electric push rod 521, and spring 613 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, and therefore will not be described in detail. The above are only specific embodiments of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
