Description

Technical Field

[0001] The present invention relates to the technical field of intelligent charging of electric vehicles, and in particular to an intelligent charging device for an electric vehicle. Background Art

[0002] As the world pays more attention to reducing carbon emissions and addressing climate change, electric vehicles are seen as an important means to reduce carbon emissions in the transportation sector. Smart charging devices further promote the environmental protection characteristics of electric vehicles by optimizing the charging process and improving energy efficiency. Although the electric vehicle market is growing rapidly, the construction of charging infrastructure often lags behind, resulting in inconvenience for users to charge. Smart charging stations can provide remote monitoring, automatic billing, fast charging and other functions to improve the efficiency of charging facilities and user experience. Smart charging devices improve users' charging experience and enhance the attractiveness of electric vehicles by providing real-time charging status, remaining charging time, charging costs and other information, as well as remote control through mobile phone applications.

[0003] When charging an electric vehicle, it needs to be charged through an outdoor charging pile. Insert the charging plug of the electric vehicle into the charging port of the charging pile. After the charging pile is powered on, the electric vehicle can be charged. The charging head of the electric vehicle is prone to wear after long-term use, which makes it easy to loosen from the socket when charging. Looseness between the charging head and the socket will lead to poor contact and unstable current transmission, which may cause the charging speed to slow down or even fail to charge normally. Sometimes, there will be some people who are greedy for cheapness or people who seek their own convenience. When other people's electric vehicles have not been fully charged, they will unplug the charging plug of other people's electric vehicles, and then use the charging socket to charge their own electric vehicles.

[0004] Therefore, the present invention proposes an intelligent charging device for electric vehicles to improve the shortcomings of traditional technologies and prevent the electric vehicle from being unplugged while charging. If the electric vehicle is unplugged maliciously during charging, the charging socket interface will be closed to prevent it from being plugged in again. Summary of the invention

[0014] The intelligent charging device for electric vehicles provided by the present invention has the following beneficial effects:

[0015] 1. Through the coordinated use of protective auxiliary components, when the electric vehicle needs to be charged, the electric vehicle plug can be placed in the placement frame plate, and the placement frame plate can be controlled by the driving device to push the protective plate to rotate and then enter the charging socket for charging, thereby realizing automatic insertion.

By adjusting the transmission ratio of the first gear and the auxiliary rack, the rotation and closing speed and force of the protective plate can be more accurately controlled, so that the protective plate can be closed smoothly, reducing impact force and noise.

[0016] 2. Through the coordinated use of the first threaded rod, the first clamping plate, the second threaded rod and the second clamping plate, the four sides of the electric vehicle plug are clamped and fixed during the insertion and removal of the electric vehicle plug by the frame plate, which can prevent the electric vehicle from being stolen and unplugged during charging, and prevent others from unauthorized unplugging of the plug, thereby avoiding the occurrence of unauthorized charging. Users do not have to worry about the plug being unplugged by others, and the charging process is more secure. Through clamping and fixing, the electric vehicle plug can be prevented from shaking during the insertion or removal process, ensuring the stability of the connection between the electric vehicle plug and the charging socket, and avoiding charging interruptions caused by poor contact. Clamping and fixing on the four sides of the electric vehicle plug can effectively reduce the impact on the plug during insertion or removal, and extend the service life of the plug. Through the position setting of the second gear, the first rack, the third gear and the second rack, when the electric vehicle plug is completely pulled out of the charging socket, the gear and the rack are meshed so that the clamping plate does not clamp it. Before the electric vehicle plug is inserted into the charging socket, it is positioned and clamped to ensure that the electric vehicle plug is accurately positioned before insertion.

[0017] 3. Through the coordinated use of protective auxiliary components, the protective plate can close the opening at the charging socket when the electric vehicle is not charging. The protective plate can prevent water, dust and other debris from entering the charging socket, reducing the risk of electrical failure and damage caused by water ingress or dust accumulation. The closed protective plate can prevent children or other people from accidentally touching the charging socket, avoiding electric shock accidents. If the electric vehicle plug is pulled out forcefully by others using tools, the charging device body will control the blocking plate to move downward through the controller to block the protective plate when it does not detect that the user has closed it through the client. The blocking of the blocking plate can prevent others from inserting their own electric vehicle plugs again. By preventing unauthorized plug insertion, the device can be prevented from being abused. The use of the anti-droop bracket can support the wires of the electric vehicle plug after the electric vehicle plug is inserted to prevent the gravity of the wires from making the electric vehicle plug insertion unstable. The anti-droop bracket can also prevent the connection between the wires and the electric vehicle plug from being worn and broken. BRIEF DESCRIPTION OF THE DRAWINGS

The blocking of the blocking plate 513 can prevent others from inserting their electric vehicle plug 3 again. By preventing unauthorized plug insertion, the device can be prevented from being abused. The anti-droop bracket 512 can be used to support the wires of the electric vehicle plug 3 after the electric vehicle plug 3 is inserted to prevent the gravity of the wires from making the insertion of the electric vehicle plug 3 unstable. The anti-droop bracket 512 can also prevent the connection between the wires and the electric vehicle plug 3 from being worn and broken.

[0037] A square groove 52 is provided on the inner wall of the charging device body 2, and a fixing plate 53 is fixedly connected to the inner wall of the square groove 52. A first connecting rod 54 is rotatably connected to the outer surface of the fixing plate 53, and a second connecting rod 55 is rotatably connected to the end of the first connecting rod 54 away from the fixing plate 53. A fixing shell 57 is fixedly connected to the bottom of the protective plate 51, and a rotating column 56 is rotatably connected to the interior of the fixing shell 57. A first gear 58 is fixedly connected to the outer surface of the rotating column 56 located at one end inside the fixing shell 57, and an auxiliary rack 59 is meshingly connected to the outer surface of the first gear 58. A slide plate 510 and a spring plate 511 are fixedly connected to the two ends of the auxiliary rack 59, respectively. A hole is provided on the surface of the slide plate 510, so that the slide plate 510 encounters less resistance when sliding inside the fixing shell 57, thereby improving the sliding efficiency of the slide plate 510. The end of the second connecting rod 55 away from the first connecting rod 54 is fixedly connected to the end of the rotating column 56 located outside the fixing shell 57. The slide plate 510 and the spring plate 511 both slide inside the fixing shell 57, and the spring plate 511 is meshed with the outer surface of the first gear 58. One end of the spring plate 511 away from the auxiliary rack 59 is fixedly connected to the inner wall of the fixed shell 57. Through the coordinated use of the protective auxiliary component 5, when the electric vehicle needs to be charged, the electric vehicle plug 3 can be placed in the placement frame plate 62, and the placement frame plate 62 is controlled by the driving device to push the protective plate 51 to rotate and enter the charging socket 4 for charging, thereby realizing automatic insertion. When not charging, the placement frame plate 62 drives the electric vehicle plug 3 to leave the charging socket 4, and the spring plate 511 is reset to realize the automatic closing of the protective plate 51. The design of automatically inserting and removing the charging plug eliminates the need for manual operation by the user, avoids direct contact between the user and the charging plug during charging, reduces the risk of electric shock, and improves the safety of the charging process. The first gear 58 and the auxiliary rack 59 can be used in conjunction with the spring plate 511. By adjusting the transmission ratio of the first gear 58 and the auxiliary rack 59, the rotation and closing speed of the protective plate 51 and the force can be more accurately controlled, so that the protective plate 51 can be smoothly closed to reduce impact force and noise.

[0038] The anti-theft assembly 6 includes a transmission plate 61, one end of the transmission plate 61 away from the placement frame plate 62 is driven and installed on an external drive device, and the external drive device is preferably a cylinder, which is arranged inside the charging device body 2. The extension and contraction of the cylinder can control the parallel movement of the transmission plate 61. The outer surface of the transmission plate 61 is fixedly connected to the placement frame plate 62, and the placement frame plate 62 is provided with a first slide groove 63. The first slide groove 63 is rotatably connected to the first threaded rod 64. The outer surfaces of the first threaded rod 64 and the second threaded rod 69 are provided with symmetrical thread grooves, and the first clamping plate 65 and the second clamping plate 610 are threadedly connected to the thread grooves. In this way, the rotation of the first threaded rod 64 or the second threaded rod 69 can drive the two first clamping plates 65 or the second clamping plates 610 to move closer to and away from each other at the same time. The outer surfaces of both ends of the first threaded rod 64 are threadedly connected to the first clamping plates 65, and one end of the first threaded rod 64 located outside the placement frame plate 62 is fixedly connected to the second gear 66, and the outer surface of the second gear 66 is meshedly connected to the first rack 67. A second slide groove 68 is provided inside the placement frame plate 62, and the second threaded rod 69 is rotatably connected inside the second slide groove 68. The outer surfaces of both ends of the second threaded rod 69 are threadedly connected to the second clamping plates 610. One end outside the placement frame 62 is fixedly connected with a third gear 611, and the outer surface of the third gear 611 is meshedly connected with a second rack 612. Through the coordinated use of the first threaded rod 64, the first clamping plate 65, the second threaded rod 69 and the second clamping plate 610, the placement frame 62 drives the electric vehicle plug 3 to be inserted and removed to clamp and fix the four sides of the electric vehicle plug 3, which can prevent the electric vehicle from being stolen during charging, and prevent others from unauthorizedly pulling out the plug, thereby avoiding the occurrence of unauthorized charging. The user does not have to worry about the plug being pulled out by others, and the charging process is more secure. The electric vehicle plug 3 can be prevented from being inserted and removed by clamping and fixing. Shaking during insertion or removal ensures the stability of the connection between the electric vehicle plug 3 and the charging socket 4 and avoids charging interruption caused by poor contact. Clamping and fixing on four sides of the electric vehicle plug 3 can effectively reduce the impact on the plug when inserted or removed, and extend the service life of the plug. Through the position setting of the second gear 66, the first rack 67, the third gear 611 and the second rack 612, the gear and the rack are engaged in a limited space when the electric vehicle plug 3 is completely pulled out of the charging socket 4 so that the clamping plate does not clamp it. The electric vehicle plug 3 is positioned and clamped before it is inserted into the charging socket 4, ensuring that the electric vehicle plug 3 is accurately positioned before insertion.

[0039] The two first clamping plates 65 and the second clamping plates 610 are both provided with rubber pads on the sides close to each other. The rubber pads have good elasticity and buffering properties, and can absorb and disperse the energy generated by the impact or vibration of the first clamping plates 65 and the second clamping plates 610, thereby protecting the first clamping plates 65 and the second clamping plates 610 and the electric vehicle plug 3 from damage. The surface of the rubber pads has a certain roughness, which can increase the friction between the first clamping plates 65 and the second clamping plates 610 and the electric vehicle plug 3, and prevent the electric vehicle plug 3 from sliding on the first clamping plates 65 and the second clamping plates 610. The upper surface of the first rack 67 is fixedly connected to the top of the inner wall of the charging device body 2, and the side of the second rack 612 away from the third gear 611 is fixedly connected to the inner side of the inner wall of the charging device body 2.

[0040] The following is the entire working process and working principle of the above embodiment:

[0041] In the initial state, the cylinder is in an extended state, the placement frame plate 62 is located outside the charging device body 2, the protective plate 51 closes the opening of the charging device body 2, the spring plate 511 is not squeezed, the second gear 66 is not engaged with the first rack 67, and the third gear 611 is not engaged with the second rack 612.

[0042] The intelligent charging device provides real-time charging status, remaining charging time, charging fee and other information, and is controlled through a mobile phone application. When the user needs to use it, he can pay for charging by scanning the code. The client will control the electric telescopic rod to retract through the controller. The retraction of the electric telescopic rod drives the blocking plate 513 to move upward to prevent the protective plate 51 from being blocked. In this way, the protective plate 51 can close the opening at the charging socket 4 when the electric vehicle is not charging. The protective plate 51 can prevent water, dust and other debris from entering the charging socket 4, reducing the risk of electrical failure and damage caused by water ingress or dust accumulation. The closed protective plate 51 can prevent children or other people from accidentally touching the charging socket 4, avoiding electric shock accidents. The user The electric vehicle plug 3 is placed in the placement frame plate 62. The size of the placement frame plate 62 can be adapted and embedded in the electric vehicle plug 3. The user starts charging by using the mobile phone control. The client controls the cylinder to start. The cylinder contracts and drives the transmission plate 61 to move toward the inside of the charging device body 2. When the transmission plate 61 moves, it drives the placement frame plate 62 to move. When the placement frame plate 62 drives the second gear 66 and the third gear 611 to mesh with the first rack 67 and the second rack 612 respectively, when meshing, the placement frame plate 62 moves and drives the second gear 66 and the third gear 611 to roll on the first rack 67 and the second rack 612. The second gear 66 and the third gear 611 rotate and drive the first clamping plate 65 meshed with them respectively. The second clamping plate 610 is moved toward the direction of the electric vehicle plug 3 to clamp and fix it on four sides. After the electric vehicle plug 3 is fixed, the second gear 66 and the third gear 611 are not meshed with the first rack 67 and the second rack 612. The placement frame plate 62 drives the electric vehicle plug 3 to be inserted into the charging socket 4 for charging. Through the coordinated use of the first threaded rod 64, the first clamping plate 65, the second threaded rod 69 and the second clamping plate 610, the placement frame plate 62 drives the electric vehicle plug 3 to be inserted and removed to clamp and fix the four sides of the electric vehicle plug 3, which can prevent the electric vehicle from being stolen while charging, and can prevent others from unauthorizedly pulling out the plug, thereby avoiding the occurrence of unauthorized charging. The user does not have to worry about the plug being pulled out by others, and the charging The process is more secure. Clamping and fixing can prevent the electric vehicle plug 3 from shaking during the insertion or removal process, ensure the stability of the connection between the electric vehicle plug 3 and the charging socket 4, and avoid charging interruption caused by poor contact. Clamping and fixing on the four sides of the electric vehicle plug 3 can effectively reduce the impact on the plug when it is inserted or removed, and extend the service life of the plug. Through the position setting of the second gear 66, the first rack 67, the third gear 611 and the second rack 612, the gear and the rack are engaged in a limited space when the electric vehicle plug 3 is completely pulled out of the charging socket 4 so that the clamping plate does not clamp it. Before the electric vehicle plug 3 is inserted into the charging socket 4, it is positioned and clamped to ensure that the electric vehicle plug 3 is accurately positioned before insertion.

[0043] At the same time, when the placement frame plate 62 drives the electric vehicle plug 3 to be inserted into the charging socket 4, the placement frame plate 62 will touch and push the protective plate 51, and the protective plate 51 rotates on the inner wall of the charging device body 2. When the protective plate 51 rotates, it drives the fixed shell 57 to rotate synchronously. When the fixed shell 57 rotates, it drives the rotating column 56 to rotate. The rotating column 56 drives the end of the second connecting rod 55 fixedly connected to it to rotate, and the second connecting rod 55 rotates toward the inside of the charging device body 2 with the end of the first connecting rod 54 away from the fixed plate 53 as the center. When the second connecting rod 55 moves with the protective plate 51, it will cause the rotating column 56 to rotate inside the fixed shell 57. During the movement of the second connecting rod 55, it will drive the second connecting rod 55 to rotate. A connecting rod 54 rotates, and the rotating column 56 rotates to drive the first gear 58 to rotate. The first gear 58 rotates to drive the auxiliary rack 59 to move in the direction of the spring plate 511. The auxiliary rack 59 squeezes the spring plate 511 to deform it. The auxiliary rack 59 drives the slide plate 510 to slide inside the fixed shell 57. The protection plate 51 rotates to drive the anti-droop bracket 512 to rotate. After the anti-droop bracket 512 rotates, it is located under the wires of the electric vehicle plug 3. Through the use of the anti-droop bracket 512, the wires of the electric vehicle plug 3 can be supported after the electric vehicle plug 3 is inserted to prevent the gravity of the wires from making the insertion of the electric vehicle plug 3 unstable. The anti-droop bracket 512 can also prevent the connection between the wires and the electric vehicle plug 3 from being worn and broken.

[0044] At this time, the protective plate 51 has opened the opening of the charging device body 2, so that the electric vehicle plug 3 can be inserted into the charging socket 4. When the user finishes charging, the placement frame plate 62 drives the electric vehicle plug 3 to move out of the charging device body 2. During the movement of the placement frame plate 62, the extrusion force exerted on the spring plate 511 gradually disappears. The elastic force of the spring plate 511 resets the auxiliary rack 59 to move, and the auxiliary rack 59 moves away from the spring plate 511. When the auxiliary rack 59 moves, it drives the first gear 58 to rotate. The rotation of the first gear 58 drives the rotating column 56 to rotate. The rotation of the rotating column 56 drives one end of the second connecting rod 55 to rotate with the other end of the first connecting rod 54 as the center. The second connecting rod 55 drives the protective plate 51 to reset and close the opening of the charging device body 2. Through the coordinated use of the protective auxiliary component 5, the electric vehicle can be charged when it needs to be charged. By placing the electric vehicle plug 3 into the placement frame plate 62, the placement frame plate 62 is controlled by the driving device to push the protective plate 51 to rotate and then enter the charging socket 4 for charging, thereby realizing automatic insertion. When not charging, the placement frame plate 62 drives the electric vehicle plug 3 to leave the charging socket 4, and the spring plate 511 is reset to realize the automatic closing of the protective plate 51. The design of automatically inserting and removing the charging plug eliminates the need for manual operation by the user, thus avoiding direct contact between the user and the charging plug during charging, reducing the risk of electric shock and improving the safety of the charging process. The first gear 58 and the auxiliary rack 59 can be used in conjunction with the spring plate 511. By adjusting the transmission ratio of the first gear 58 and the auxiliary rack 59, the rotation and closing speed and strength of the protective plate 51 can be more accurately controlled, so that the protective plate 51 can be smoothly closed to reduce impact force and noise.

[0045] If the anti-theft assembly 6 is damaged by someone else using tools and the electric vehicle plug 3 is pulled out forcefully during charging, the charging device body 2 will control the electric telescopic rod to extend through the controller when it does not detect that the user has closed it through the client. At this time, the protective plate 51 will automatically close the opening of the charging device body 2 when the electric vehicle plug 3 is pulled out. The extension of the electric telescopic rod drives the blocking plate 513 to move downward to block the protective plate 51. The blocking of the blocking plate 513 can prevent others from inserting their own electric vehicle plug 3 again. By preventing unauthorized plug insertion, the device can be prevented from being abused.
