The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0043] like Figure 1 As shown, in the field of ship battery replacement, during the process of charging the battery, it is necessary to control the electrical connection device 100 to move toward the battery and make the power plug in the electrical connection device 100 successfully dock with the battery interface. However, due to errors, the power plug and the battery interface are not accurately docked, affecting the charging efficiency and effect.

[0044] In order to solve the above problems, Figures 2 to 12 As shown, the embodiment of the utility model provides an electrical connection device, comprising:

[0045] A first bracket 1, wherein a first mounting hole 11 is provided on the first bracket 1;

[0046] a power plug 2 for electrically connecting to the battery, the power plug 2 being connected to the first bracket 1, and a plug end of the power plug 2 being exposed through the first mounting hole 11;

[0047] A second bracket 3, wherein at least one second mounting hole 31 is provided on the second bracket 3, and a guide rod 4 corresponding to the second mounting hole 31 is provided on the first bracket 1, wherein the guide rod 4 is inserted into the corresponding second mounting hole 31, and the diameter of the second mounting hole 31 is larger than the diameter of the guide rod 4;

[0048] A floating component 5 is also provided on the guide rod 4, and the first bracket 1 and the second bracket 3 are connected through the floating component 5; through the floating component 5, when the power plug 2 is in the plugged state, the guide rod 4 can move relatively in the second mounting hole 31 to drive the power plug 2 to move; when the power plug 2 is out of the plugged state, the floating component 5 presses against the first bracket 1 and the second bracket 3, and the power plug 2 is fixed relative to the second bracket 3.

[0049] In the embodiment of the utility model, Figure 5 As shown, the first bracket 1 is provided with a first mounting hole 11 and a plurality of guide rods 4. Figure 6 As shown, the second bracket 3 is provided with a plurality of second mounting holes 31, wherein the guide rods 4 correspond to the second mounting holes 31 one by one, and the diameter of the second mounting holes 31 is larger than the diameter of the guide rods 4, so that the guide rods 4 can move freely within the aperture range and can also produce a certain inclination; Figure 3 As shown, the power plug 2 is connected to the first bracket 1, and the plug-in end of the power plug 2 is exposed through the first mounting hole 11. The first bracket 1 and the second bracket 3 are fixedly connected by a floating component 5 and a second mounting hole 31 through a guide rod 4, so that the power plug 2 has a floating function during the electrical connection with the battery.

[0050] During the process of electrical connection between the electrical connection device 100 and the battery, the electrical connection device 100 moves toward the battery. After the power plug 2 contacts the battery surface, the power plug 2 is in a plug-in state. At this time, the floating component 5 is compressed, and the guide rod 4 can move relatively in the second mounting hole 31, driving the power plug 2 to move longitudinally and / or laterally relative to the second bracket 3, effectively reducing the distance error, angle error and position error during the docking process between the power plug 2 and the battery, making the docking between the power plug 2 and the battery more accurate, and improving the charging effect and efficiency; when the power plug 2 is out of the plug-in state, the floating component 5 recovers and presses against the first bracket 1 and the second bracket 3, so that the power plug 2 is fixed relative to the second bracket 3, and the electrical connection device 100 can quickly and accurately return to the initial state, which is convenient for use and improves the user experience.

[0054] Among them, the first retaining ring 51 and the sliding assembly 53 are used to fix the spring 52, which is beneficial to the compression and reset of the spring 52; the other side of the sliding assembly 53 is in contact with the second bracket 3 and has a sliding function, so that no matter whether the power plug 2 is in the plug-in state or the unplugged state, the friction between the sliding assembly 53 and the second bracket 3 can be reduced, and the whole process is smoother; the second retaining ring 54 and the spherical nut 55 cooperate with each other. When the power plug 2 is in the plugged state, the guide rod 4 drives the spherical nut 55 to disengage from the second retaining ring 54, and the floating assembly 5 is in an active state. The guide rod 4 can move freely within the aperture range of the second mounting hole 31, and can also produce a certain inclination, thereby driving the power plug 2 to move longitudinally and / or laterally relative to the second bracket 3. When the power plug 2 is in the unplugged state, the guide rod 4 drives the spherical nut 55 to embed into the second retaining ring 54, and the floating assembly 5 is in a fixed state, abutting against the first bracket 1 and the second bracket 3, thereby driving the power plug 2 to be fixed relative to the second bracket 3.

Fig. 9 As shown, the outer surface of the spherical nut 55 includes a spherical portion that can cooperate with the curved portion 530; wherein, when the power plug 2 is in a disconnected state, the guide rod 4 drives the spherical nut 55 to embed into the second retaining ring 54. At this time, the spherical portion cooperates with the curved portion 530, and the floating component 5 is in a fixed state, abutting against the first bracket 1 and the second bracket 3, thereby driving the power plug 2 to be fixed relative to the second bracket 3. When the power plug 2 is in a plugged state, the guide rod 4 drives the spherical nut 55 to disengage from the second retaining ring 54, the spherical portion does not cooperate with the curved portion 530, and the floating component 5 is in an active state. The guide rod 4 can move freely within the aperture range of the second mounting hole 31, and can also produce a certain inclination, thereby driving the power plug 2 to move longitudinally and / or laterally relative to the second bracket 3.
