Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging, in particular to a vehicle charging interface docking structure. Background Art

[0002] New energy vehicles refer to vehicles that use new energy to replace traditional fuel, mainly including pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Currently, common new energy vehicles use electric power sources, which are environmentally friendly, energy-saving and low-emission. The quality of charging gun docking is directly related to whether there will be safety hazards during the charging process. An unqualified charging gun docking operation may cause safety problems such as short circuit and leakage.

[0003] When using an existing charging gun, the user generally holds the charging gun, aligns the plug of the charging gun with the charging port of the car, and then inserts the charging gun into the charging port of the car with appropriate force until the plug is fully inserted and locked.

[0004] However, the existing plug docking process still has the following shortcomings:

[0005] When a manual handheld charging gun is docked with a car's charging port, the initial docking accuracy is low. During the process of plugging and unplugging, the plug and the interface will be subjected to radial force, which will cause great damage to the plug and the interface, thereby reducing their service life. In addition, the force of manual plugging and unplugging is difficult to control, which may result in improper insertion or excessive insertion, causing damage. Utility Model Content

[0033] Embodiment 1:

[0034] See also Figures 1 to 6 In an embodiment of the utility model, a car charging interface docking structure includes a docking component embedded in the front end of a charging gun housing 1 and a connecting component used in conjunction with the docking component, and the connecting component is fixedly installed at the car charging port; and also includes a control component arranged on the charging gun housing 1, and the control component is electrically connected to the connecting component;

[0035] A plug 8 is installed in the docking component, and a charging head 15 is installed in the connecting component; the control component is used to control the docking component to drive the plug 8 to achieve the plugging or unplugging action between the plug 8 and the charging head 15 when the docking component is docked with the connecting component.

[0036] The docking assembly includes a first circular ring 6 fixedly mounted on the front end of the charging gun housing 1, a mounting plate 4 located inside the charging gun housing 1 is arranged on one side of the first circular ring 6 close to the charging gun housing 1, and a plurality of connecting rods 5 are fixedly connected between the periphery of the mounting plate 4 and the edge of the first circular ring 6;

[0037] An electric push rod 7 coaxial with the first circular ring 6 is fixedly mounted on the side of the mounting plate 4 close to the first circular ring 6, and a plug 8 is fixedly mounted on one end of the electric push rod 7 away from the mounting plate 4;

[0038] A plurality of groups of positioning members arranged in an axial array about the axis of the first circular ring 6 are fixedly mounted on the periphery of the first circular ring 6 .

[0039] The positioning member includes a protrusion 11 fixedly mounted on the periphery of the first ring 6, a movable groove 20 is provided on the side of the protrusion 11 away from the first ring 6, a positioning block 12 is slidably mounted in the movable groove 20, and a plurality of springs 19 are fixedly connected between one end of the positioning block 12 located inside the movable groove 20 and the inner end surface of the movable groove 20; the end of the positioning block 12 away from the first ring 6 is located outside the movable groove 20 under the elastic force of the spring 19;

[0040] The portion of the positioning block 12 located outside the movable slot 20 is an isosceles trapezoidal structure.

[0041] The connecting assembly includes a second ring 9 fixedly mounted at the charging port of the vehicle, the inner side of the second ring 9 is provided with a mounting groove 10 embedded in the interior of the vehicle, and a charging head 15 coaxial with the second ring 9 is fixedly mounted in the mounting groove 10;

[0042] A plurality of positioning blocks 16 for use with the positioning blocks 12 are fixedly installed on the outer surface of the installation groove 10 near its edge. The plurality of positioning blocks 16 are arranged in an array circumferentially about the axis of the installation groove 10, and the number of the plurality of positioning blocks 16 is equal to the number of the plurality of positioning blocks 12.

[0043] A positioning groove 18 that matches the positioning block 12 is provided in the middle of the inner side of the positioning block 16 , and a limiting plate 17 that cooperates with the protrusion 11 is fixedly mounted on the inner side of the positioning block 16 at the end away from the second ring 9 .

[0044] When the utility model is in use:

[0045] Hold the charging gun housing 1, and fit the first ring 6 and the second ring 9 together. At this time, the multiple protrusions 11 and the multiple positioning blocks 16 are axially staggered. Then rotate the charging gun housing 1, so that the first ring 6 drives the multiple protrusions 11 to rotate, so that the multiple protrusions 11 overlap with the multiple positioning blocks 16 respectively. During the process, when the positioning block 16 contacts the positioning block 12, the inclined surface of the positioning block 12 is subjected to pressure, so that the positioning block 12 adaptively slides into the movable groove 20 until the end of the positioning block 12 away from the first ring 6 is in sliding contact with the inner side surface of the positioning block 16. Then, as the first ring 6 rotates, when the positioning block 12 is aligned with the positioning groove 18 on the inner side of the positioning block 16, under the elastic force of the spring 19, the positioning block 12 extends out and resets, and extends to the positioning groove 18 at the corresponding position. At this time, the protrusion 11 is in sliding contact with the limiting plate 17, and the relative rotation between the first ring 6 and the second ring 9 is restricted, and the first ring 6 and the second ring 9 are in a coaxial state;

[0046] Then, the control component is used to extend the electric push rod 7, driving the plug 8 to be plugged and connected with the charging head 15. During the plugging process of the plug 8, the plug 8 and the charging head 15 are in a coaxial state, thereby avoiding the problem that when the plug 8 and the charging head 15 are manually aligned and plugged in, the force direction is not coaxial with the axis of the plug 8, thereby causing the plug 8 and the charging head 15 to be subjected to radial force, resulting in a reduction in the service life of the plug 8 and the charging head 15; at the same time, the electric push rod 7 can provide a stable force instead of manual force plugging and unplugging, effectively avoiding the situation where the plug is not properly plugged in or the plug is plugged in too hard and causes damage.

[0047] Moreover, in the docked state, the positioning engagement between the positioning block 12 and the positioning groove 18 limits the circumferential rotation between the plug 8 and the charging head 15, and also limits the axial movement between the plug 8 and the charging head 15, so that the two plugs 8 and the charging head 15 can maintain a stable docking state, thereby improving charging safety.

[0048] Embodiment 2:

[0049] See also Figure 1 On the basis of Example 1, the control component includes a controller disposed in a charging gun housing 1 and an insertion button 2 and an extraction button 3 mounted on the surface of the charging gun housing 1, and the insertion button 2 and the extraction button 3 are both electrically connected to the controller;

[0050] The controller is also electrically connected to the electric push rod 7 .

[0051] The controller can be a PLC (Programmable Logic Controller). By inputting commands through buttons or other input devices, the PLC controller will control the telescopic movement of the electric pusher according to the pre-written program logic. The PLC controller can execute various control logics such as start, stop, speed adjustment, position control, etc. according to different input signals and conditions, thereby achieving precise control of the electric pusher. This technology has been widely used in the field of industrial automation and is an existing technology.

[0052] In this embodiment, when charging, after pressing the insertion button 2, the electric push rod 7 drives the plug 8 to extend and dock with the charging head 15; when charging is finished, the extraction button 3 is pressed, and the electric push rod 7 drives the plug 8 to reset to the charging gun housing 1, separating the plug 8 from the charging head 15, thereby completing the automatic plugging and unplugging action instead of manual work.
