Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0021] Embodiment one, as Figures 1-6As shown, according to the embodiment of the application, a kind of global mobile intelligent charging equipment, including fixed truss 1, power supply box 2 is electrically connected on fixed truss 1, a plurality of charging sliding blocks 3 are limit slidingly connected on fixed truss 1, a plurality of charging sliding blocks 3 are electrically connected with power supply box 2, and mobile charging box 4 is detachably electrically connected on charging sliding block 3, so as to understand that, in the present application, fixed truss 1 can be used to carry out centralized charging management to multiple mobile charging boxes 4, avoid after use mobile charging box 4 random stop and place, even damaged, lost and other phenomena occur.

[0022] In the specific embodiments of the application, the mobile charging box 4 is built-in battery, and the mobile charging box 4 has the functions of direct 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 directly driven to this place for direct charging of the power supply.When the space in front of it is occupied and the vehicle cannot enter this place, and the mobile charging box 4 cannot be connected with the vehicle effectively, 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 built-in battery of the mobile charging box 4, thereby improving the practicability and convenience of the charging equipment.

[0023] The mobile charging box 4 includes a mobile box body 41, a charging gun is electrically connected to the side wall of the mobile box body 41, an electric push rod one 42 and a buffer assembly 43 are arranged at the bottom end of the mobile box body 41, the bottom end of the buffer assembly 43 can be lowered by the elongation of the piston end of the electric push rod one 42, a tracked omni-directional wheel 44 is arranged at the bottom side of the buffer assembly 43, the height of the mobile box body 41 can be changed by the extension and retraction of the piston end of the electric push rod one 42, a charging assembly 45 is electrically connected to the back side of the mobile box body 41, and the charging assembly 45 is detachably electrically connected with the charging sliding block 3.

[0024] It can be understood that when the mobile charging box 4 is connected to the charging sliding block 3, the vehicle can be directly charged with the power supply or the built-in battery is charged with energy storage, at this time the piston end of the electric push rod one 42 is retracted, and the mobile box body 41 is hung on the charging sliding block 3;when the mobile charging box 4 is separated from the charging sliding block 3, the vehicle is charged by the built-in battery, at this time the tracked omni-directional wheel 44 drives the mobile box body 41 to move by the power supply of the battery.

[0025] As shown in Figure 1 As shown, the mobile cabin 11 is arranged on one side of the fixed truss 1 along the length direction of the fixed truss 1, and the plurality of charging sliding blocks 3 are limit slidingly connected in the mobile cabin 11.

[0026] It should be noted that the charging slider 3 and the power supply box 2 can be electrically connected through a power line, and the length of the power line is set to allow the charging slider 3 to move a certain distance in the moving cabin 11, so as to change the position of the charging slider 3 on the fixed truss 1 within the stroke range, so as to have a certain flexibility and avoid fixed setting.

[0027] As shown in Figure 5 and Figure 6 , one end of the charging slider 3 extends out of the moving cabin 11, and the end is provided with a charging groove 31, the charging groove 31 is L-shaped, and a conductive strip 32 is fixedly connected in the charging groove 31. The upper end surface of the end of the charging slider 3 extending out of the moving cabin 11 is provided with a plurality of end surface positioning holes 33.

[0028] It should be noted that in the specific embodiments of the present application, the conductive strip 32 and the charging slider 3 are electrically connected, and the charging slider 3 is arranged towards the inside of the charging groove 31 to avoid being exposed to reduce the risk of electric shock caused by accidental touch, and also to some extent avoid the influence of pollution on the subsequent use of the conductive performance.

[0029] As shown in Figure 3 , the electric push rod 42 is provided with at least two, and the two electric push rods 42 are symmetrically arranged on both sides of the bottom end of the moving box 41, and are electrically connected with the built-in battery of the moving box 41.

[0030] As shown in Figure 3 and Figure 4 , the buffer assembly 43 includes a connecting column 431 fixedly connected to the bottom end of the moving box 41, a top plate 432 fixedly connected 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 rod 42, two groups of elastic members are symmetrically fixedly connected to the bottom side of the top plate 432, and a bottom plate 437 is elastically and slidably sleeved on the two groups of elastic members. The bottom plate 437 is located on the bottom side of the two electric push rods 42.

[0031] Further, the elastic member includes a hydraulic damping cylinder 433 fixedly connected to the top plate 432, a spring 434 sleeved on the hydraulic damping cylinder 433, the top end of the spring 434 is fixedly connected to the top plate 432, the bottom end of the spring 434 is fixedly connected to a limiting plate 435, the limiting plate 435 is slidably sleeved on the hydraulic damping cylinder 433, the bottom end of the hydraulic damping cylinder 433 is coaxially fixedly connected to a limiting rod 436, and the bottom plate 437 is slidably sleeved on the limiting rod 436 and fixedly connected with the limiting plate 435.

[0032] It can be understood that the electric push rod one 42 piston end retraction, its piston end and the bottom plate 437 do not contact; electric push rod one 42 piston end elongation, its piston end abuts on the bottom plate 437, and pushes the bottom plate 437 along the limiting rod 436 downward displacement, in the process of spring one 434 stretch, because the lower track type omni-directional wheel 44 is always in contact with the ground, so the electric push rod one 42 will reverse push the whole moving box 41 upward displacement, change the height of the moving box 41.

[0033] As shown in Figure 5 and Figure 6 , the charging assembly 45 includes the L-shaped back plate 451 fixedly connected to the back side of the moving box 41, the L-shaped back plate 451 is vertically provided with the conductive strip two 452 electrically connected with the internal electrical elements of the moving box 41, and the conductive strip two 452 and the conductive strip one 32 are detachably electrically connected.

[0034] Specifically, the conductive strip two 452 and the conductive strip one 32 are provided with conductive metal on the outer sides corresponding to each other, so that when the two are in contact, they form electrical communication.

[0035] Further, the conductive strip two 452 is provided with the side positioning block 453 fixedly connected to the L-shaped back plate 451 on both sides, the side positioning block 453 is provided in an L-shaped manner, the side positioning block 453 is slidingly inserted into the charging groove 31 and forms a clamping connection with the charging groove 31, and the side positioning block 453 is displaced in the height direction within the charging groove 31.

[0036] Further, the L-shaped back plate 451 is provided with a plurality of upper positioning columns 454 fixedly connected to the bottom end of the transverse section, and the upper positioning columns 454 are respectively inserted into the plurality of end face positioning holes 33.

[0037] So, it can be understood that when there is space in front of the fixed truss 1 to park a vehicle that needs to be charged, the vehicle directly drives in, at this time the moving box 41 is hung on the charging slider 3 through the charging assembly 45 and forms an electrical connection with the charging slider 3, at this time the user directly removes the charging gun on the side wall of the moving box 41, and the vehicle can be charged, at this time the power source comes from the city power connected by the power supply box 2, of course, the charging slider 3 has a certain sliding ability on the fixed truss 1, so that the moving box 41 at this time also has a certain displacement ability on the fixed truss 1, which can improve the flexibility of use; When the moving box 41 does not charge the vehicle, it can charge the battery inside itself through the electrical connection between itself and the charging slider 3 for energy storage for use; When there is no space in front of the fixed truss 1 to park a vehicle, the vehicle needs to be charged, at this time the moving box 41 needs to be removed from the fixed truss 1, that is, the electrical connection between the charging assembly 45 and the charging slider 3 needs to be disconnected, at this time the piston end of the electric push rod one 42 can be extended and abutted to the bottom plate 437, because the caterpillar omnidirectional wheel 44 is always in contact with the ground, so the bottom plate 437 cannot be displaced downward, so the fixed end of the electric push rod one 42 and the moving box 41 will be displaced upward, so it can be understood that the conductive strip two 452 originally in electrical connection in the charging groove 31 will be displaced upward and separated from the conductive strip one 32, in this process, the limiting rod 436 is separated 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 of the charging groove 31, and then the caterpillar omnidirectional wheel 44 drives the moving box 41 to displace outward, so that the side positioning block 453 is completely separated from the charging groove 31 to disconnect the electrical connection between the moving box 41 and the charging slider 3, and then the caterpillar omnidirectional wheel 44 can displace the moving box 41 to the side of the vehicle, at this time the charging gun on the moving box 41 is inserted into the vehicle charging port to charge the vehicle with the battery, after charging is completed, the moving box 41 is displaced back to the fixed truss 1, and the side positioning block 453 is inserted back into the charging groove 31, the piston end of the electric push rod one 42 is retracted, so that the conductive strip two 452 and the conductive strip one 32 form an electrical connection again. It should be noted that the caterpillar omnidirectional wheel 44 in the present application is a prior art, which has applicability to various terrains and improves the mobility of the charging equipment of the present application.

[0038] It should be noted that in the specific embodiments of the present application, the global mobile intelligent charging device of the present application can be equipped with an intelligent management system, supporting self-diagnosis, remote monitoring and intelligent scheduling, real-time viewing of charging power, current, voltage and other key parameters and fault warning information, with multiple safety protection such as overvoltage, overcurrent, low voltage, ESD, lightning protection, overcharging, overload, fire, overheating, waterproof, leakage and chip protection, etc. The global mobile intelligent charging device of the present application can be applied to many scenes such as highway service areas, residential areas and community parking lots, commercial complexes and scenic parking lots, emergency rescue, industrial parks and logistics parks, outdoor activities and tourism, etc. The intelligent control system configured therein will not be described here.

[0039] In the related art, due to the different terrains, the mobile box 41 will inevitably encounter uneven ground during movement. Although the track-type omni-directional wheel 44 has strong passability, the mobile box 41 is configured with many electrical elements such as batteries, which have a certain weight. Once the mobile box 41 tilts at a large angle during movement, it will cause the entire mobile charging box 4 to stand unstable, even fall down, seriously affecting the use, and even causing damage to the mobile charging box 4.

[0040] In some embodiments of the present application, as shown in Figures 1-3 , Figure 7 and Figure 8 , a balancing mechanism 5 is arranged between the buffer assembly 43 and the track-type omni-directional wheel 44. The balancing mechanism 5 includes an axis positioning assembly 51 fixed at both ends of the bottom end of the buffer assembly 43 and the top end of the track-type omni-directional wheel 44, and a plurality of circumferential correction assemblies 52 circumferentially arranged on the side of the axis positioning assembly 51. The top ends of the plurality of circumferential correction assemblies 52 are also fixed at both ends of the bottom end of the buffer assembly 43 and the top end of the track-type omni-directional wheel 44. The plurality of circumferential correction assemblies 52 are electrically connected to the battery and have independent extension and contraction.

[0041] Specifically, the axis positioning assembly 51 includes a support rod 511 in the middle and two spherical hinge seats 512 at both ends, which are spherical hinged with the support rod 511.

[0042] Specifically, the circumferential correction assembly 52 includes an inclined electric push rod 521, and the top and bottom ends of the electric push rod 521 are respectively hinged with a U-shaped frame 522, and the U-shaped frame 522 is rotatably connected with a fixed seat 523.

[0043] Further, the rotation directions between the electric push rod 521 and the U-shaped frame 522 and between the U-shaped frame 522 and the fixed seat 523 are respectively in two perpendicular planes.

[0044] Therefore, it can be understood that although the support rod 511 is connected to the bottom end of the buffer assembly 43 (i.e., the bottom plate 437) and the top end of the tracked omni-directional wheel 44 through the spherical hinge seats 512 at both ends to form a spherical hinge, it does not have any supporting ability when used alone. However, in cooperation with the plurality of circumferential correction assemblies 52, it can provide a certain supporting strength when the moving box 41, the support rod 511, and the tracked omni-directional wheel 44 are kept vertical and coaxial, thereby reducing the pressure borne by the circumferential correction assemblies 52. The plurality of circumferential correction assemblies 52 can change the angle of the respective electrically driven push rods 521 inside them and the fixed seats 523 relative to the top and bottom ends thereof to ensure that the moving box 41 can keep vertical when the tracked omni-directional wheel 44 encounters any terrain and the top end of the tracked omni-directional wheel 44 has an inclination angle (of course, the angle has a certain range), and adjust the center of gravity of the moving box 41 above the tracked omni-directional wheel 44 to prevent the center of gravity of the entire mobile charging box 4 from deviating and causing the mobile charging box 4 to fall over.

[0045] In the related art, the omnidirectional mobile intelligent charging device has the functions of separating from the fixed truss 1 and returning to the original position, and has the effects of charging the battery and charging the vehicle after returning to the original position. Therefore, the conductive strip two 452 on the moving box 41 and the conductive strip one 32 on the charging slider 3 need to have good contact to realize the conductive effect between them.

[0046] In some embodiments of the present application, as shown in Figures 9-11 The protection mechanism 6 includes an anti-collision plate 61 elastically inserted on one side of the side positioning block 453 facing the charging groove 31, and a centering block 62 fixed to the anti-collision plate 61 and located on the side of the side positioning block 453 away from the conductive strip two 452.

[0047] The two corners inside the charging groove 31 are symmetrically provided with inclined surfaces one 311; and the side of the side positioning block 453 facing the charging groove 31 is provided with a sliding cavity 455.

[0048] Specifically, the anti-collision plate 61 is fixedly connected with at least two guide columns 611, the two guide columns 611 are slidingly inserted in the sliding cavity 455, and the end of the guide column 611 is coaxially fixedly connected with a limiting ring 612, the limiting ring 612 is limited to slide in the sliding cavity 455, and the spring two 613 is abutted between the limiting ring 612 and the inner end of the sliding cavity 455.

[0049] Further, the side surface of the centering block 62 is provided with an inclined surface two 621, and the inclined surface two 621 and the inclined surface one 311 are matched.

[0050] Therefore, it can be understood that when the mobile box 41 is homing, the charging assembly 45 is inserted into the charging groove 31, and the two side centering blocks 62 are contacted and formed by the inclined surface part 621 and the notch of the charging groove 31, which can form a centering action between the charging groove 31 and the charging assembly 45, preventing the side positioning block 453 from directly impacting the charging sliding block 3. Secondly, during the displacement of the side positioning block 453 into the charging groove 31 after the centering action is formed, the anti-collision plate 61 will first abut against the inner wall of the charging groove 31, and during the continuous displacement, the limiting ring 612 will be forced to extrude the spring 613, and the spring 613 will be used to change the rigid collision formed during the insertion process into a flexible collision, reduce the vibration sensation formed by the insertion between the charging sliding block 3 and the charging assembly 45, reduce the damage probability, and improve the service life of the entire charging device.

[0051] It should be noted that the specific model specifications of the power supply box 2, the electric push rod 42, the tracked omni-directional wheel 44, the hydraulic damping cylinder 433, the spring 434, the electric push rod 521 and the spring 613 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail. Above, only the specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
