[0036] See also Figure 1 to Figure 2 , a specific embodiment of the utility model is a drawer-type floating docking device, which is used to dock with the plug-in female head 7 provided on the energy vehicle 6 to realize charging of the energy vehicle 6. The drawer-type floating docking device includes a fixed gun frame 1, and a floating component 2 is provided on the fixed gun frame 1, and a plug-in head 3 is provided on the floating component 2. The plug-in head 3 can be docked with the plug-in female head 7 provided on the energy vehicle 6, and the charging operation of the energy vehicle 6 can be realized after the docking is completed. In addition, during the docking process, the floating component 2 has a floating amount of the X-axis and the Y-axis, that is, during docking, the floating component 2 can drive the plug-in head 3 provided thereon to float synchronously along the X-axis and the Y-axis, and can control the plug-in head 3 and the energy vehicle 6 to always be at a set distance between the two during docking.

[0037] See also Figure 3The floating assembly 2 includes a fixed plate 21, a first floating member 22, and a second floating member 23, wherein the first floating member 22 is arranged on the fixed plate 21 and can move synchronously with the fixed plate 21. The second floating member 23 is arranged on the first floating member 22 in a stacked manner, and the second floating member 23 can move along the X-axis and the Y-axis on the first floating member 22. Specifically, the size of the second floating member 23 is smaller than that of the first floating member 22, and the first floating member 22 can drive the second floating member 23 to move synchronously during the movement process. When the first floating member 22 moves, the second floating member 23 can move relative to the first floating member 22 on the X-axis and the Y-axis.

[0038] See also Figure 5 The fixed gun rack frame 1 is also provided with a linear guide slider assembly 4 and a compression spring assembly 5, wherein the linear guide slider assembly 4 is connected to the fixed plate 21. Since the linear guide slider assembly 4 can move along a straight line, the linear guide slider is configured to move along the width direction of the fixed gun rack frame 1. Therefore, the linear guide slider assembly 4 can drive the fixed plate 21 to move synchronously along the width direction of the fixed gun rack frame 1.

[0039] The linear guide slider assembly 4 includes a linear guide 41 and a slider 42, wherein a plurality of linear guides 41 may be provided, wherein two linear guides 41 are provided, the two linear guides 41 are provided in parallel and symmetrically, and each linear guide 41 is provided with at least one slider 42, the fixed plate 21 is provided on the slider 42 and is fixedly connected to the plurality of sliders 42 at the same time, and thus when the plurality of sliders 42 move on the linear guide 41, they can synchronously drive the fixed plate 21 provided thereon to move along the linear guide 41.

[0040] In addition, a compression spring assembly 5 is provided between the two linear guide rails 41, and the compression spring assembly 5 is provided in parallel with the two linear guide rails 41. The compression spring assembly 5 includes a guide rod 51, and mounting seats 52 are respectively provided at both ends of the guide rod 51, and the mounting seats 52 are fixedly installed on the fixed gun rack frame 1 to achieve the installation and fixation of the guide rod 51. A compression spring 53 and a guide plate 54 are sleeved on the guide rod 51, and the guide plate 54 is connected to the fixed plate 21, so that when the energy vehicle 6 contacts the floating assembly 2, the fixed plate 21 can be pushed along the linear guide rail 41. When the energy vehicle 6 contacts the floating component 2, the fixed plate 21 can be pushed along the linear guide rail 41, and at the same time, the guide plate 54 compresses the compression spring 53 and shrinks the compression spring 53. After the compression spring 53 shrinks, it can drive the floating component 2 to shrink synchronously until the energy vehicle 6 stops. At this time, the compression spring 53 is no longer subjected to the pressure applied by the energy vehicle 6, and then stops shrinking. At this time, the female plug 7 on the energy vehicle 6 and the plug-in head 3 set on the floating component 2 are within the set distance range; and when the energy vehicle 6 is charged and moves away from the floating component 2, the pressure applied by the energy vehicle 6 to the compression spring 53 is reduced, so the compression spring 53 gradually extends to reset, and as the energy vehicle 6 moves away, the distance between the plug-in head 3 on the floating component 2 and the energy vehicle 6 can also be maintained within the set range. Therefore, through the mutual cooperation between the linear guide rail 41 component and the floating component 2, the distance between the energy vehicle 6 is always at a constant distance during the process of moving away or approaching, and the distance between the two is maintained through the mechanical structure, without the need for additional software development, thereby making the overall cost lower.

[0041] See also Figure 3 to Figure 4When the plug-in head 3 provided on the floating assembly 2 is docked with the plug-in female head 7 provided on the energy vehicle 6, the proximity switch provided on the energy vehicle 6 senses the metal sheet provided on the fixed gun rack frame 1, and the energy vehicle 6 slowly stops. When the two are in contact, the floating amount of the plug-in head 3 is realized by the first floating member 22 and the second floating member 23. Among them, the first floating member 22 is provided with a first elastic member 221 and a first fixed member 222, and the bottom of the second floating member 23 is provided with a first docking member 231. During installation, one end of the first elastic member 221 is connected to the first fixed member 222, and the other end of the first elastic member 221 is hooked with the first docking member 231. Therefore, the floating amount of the second floating member 23 is the elastic deformation range of the first elastic member 221. The second floating member 23 is also provided with a mounting plate 232, on which the plug-in head 3 is arranged, and inside the second floating member 23 are also provided with a second elastic member 233 and a second fixing member 234, and a second docking member 2321 is provided at the bottom of the mounting plate 232, one end of the second docking member 2321 is connected to the second fixing member 234, and the other end of the second elastic member 233 is hooked with the second docking member 2321. The second elastic members 233 are distributed on the inner circumference of the second floating member 23, and each second elastic member 233 is correspondingly hooked with the second docking member 2321. Therefore, through the elastic deformation generated between each second elastic member 233, the maximum range of movement of the mounting plate 232 is within the elastic deformation range of the second elastic member 233. It should be noted that the first elastic member 221 and the second elastic member 233 can use springs to achieve floating amount adjustment.

[0042] In order to further limit the range of movement of the mounting plate 232, a limiting hole 2322 is provided on the mounting plate 232, a floating limiting member 235 is provided in the second floating member 23, and two ends of the floating limiting member 235 are respectively fixedly connected to the inner upper end surface and the inner lower end surface of the second floating member 23, and then pass through the limiting hole 2322. Therefore, when the mounting plate 232 is floating, the maximum floating range of the mounting plate 232 does not exceed the range defined by the limiting hole 2322.

[0043] In addition, when the floating amount needs to be increased, the floating amount of the plugging head 3 on the second floating member 23 can be effectively increased by increasing the area defined by the limiting hole 2322. However, it should be noted that increasing the area of ​​the limiting hole 2322 will inevitably increase the volume of the floating assembly 2, and correspondingly, the volume of the plugging female head 7 also needs to be increased synchronously, so that when the plugging head 3 is at the extreme position, the plugging female head 7 can also complete the docking with the plugging head 3.
