Detailed Implementation
[0019] like Figures 1 to 9 As shown, a floating charging device in this embodiment includes an upper charging seat 1 and a lower charging seat 2. A charging head 3 is connected to the upper charging seat 1, and a contact head 4 is connected to the lower charging seat 2. Multiple charging heads 3 and multiple contact heads 4 are provided, with each multiple charging head 3 corresponding to a multiple contact head 4, and the multiple charging heads 3 are arranged side by side. The charging base 1 is provided with a connecting mechanism 5, which includes a fixing plate 41 and a connecting plate 42. The fixing plate 41 is fixedly connected to the charging base 1, and the connecting plate 42 is located on one side of the fixing plate 41. The connecting plate 42 is connected to the fixing plate 41 by a first spring 43. Four first springs 43 are provided and distributed in a matrix. The connecting plate 42 and the fixing plate 41 are connected by a support rod ball joint bearing 44. The charging head 3 is connected to the connecting plate 42. During installation, the lower charging seat 2 is installed in the charging position, and the contact head 4 is connected to the power supply. The upper charging seat 1 is installed on the stretcher, and the charging head 3 is connected to the communication system. During charging, the upper charging seat 1 and the lower charging seat 2 are connected, and the charging head 3 and the contact head 4 are aligned and abutted against each other. In this way, charging is achieved. Here, when the charging head 3 abuts against the contact head 4, the ball joint bearing 44 of the support rod can move at angles in multiple directions, causing relative rotation between the connecting plate 42 and the fixed plate 41, and causing the first spring 43 to deform. Through the elastic action of the first spring 43, the buffer is achieved when the charging head 3 abuts against the contact head 4. In this way, the wear of the charging head 3 abuts against the contact head 4 can be reduced, and the charging reliability can be improved. Moreover, through the elastic force of the first spring 43, it is also easy for the charging head 3 to abut against the contact head 4, that is, to further improve the charging reliability. A mounting base 45 is fixedly provided on the connecting plate 42. A mounting slot 46 is provided on the mounting base 45. The charging head 3 is movably inserted into the mounting slot 46. The charging head 3 is connected to the mounting base 45 through a second spring 47. The number of mounting slots 46 is set to be multiple, and the multiple mounting slots 46 correspond one-to-one with the multiple charging heads 3. The mounting base 45 includes a base body 451 and an end cap 452. The mounting groove 46 is located on the base body 451, and the end cap 452 covers the mounting groove 46. The charging head 3 passes through the end cap 452. The charging head 3 includes a sliding part 31 and a charging part 32. The sliding part 31 is located in the mounting groove 46 and is connected to the second spring 47. The charging part 32 is disposed at one end of the sliding part 31, and the end of the charging part 32 near the sliding part 31 abuts against the end cover 452. When the charging head 3 abuts against the contact head 4, the charging head 3 retracts into the mounting groove 46, and the second spring 47 deforms. The elastic action of the second spring 47 further buffers the charging head 3 when it abuts against the contact head 4. Moreover, the elastic force of the second spring 47 also facilitates the charging head 3 to abut against the contact head 4, improving charging reliability. When the charging head 3 separates from the contact head 4, the elastic action of the second spring 47 causes the charging head 3 to move in the opposite direction to reset, and the end of the charging part 32 near the sliding part 31 abuts against the end cover 452. In this way, the charging head 3 is positioned. The charging upper seat 1 includes a first charging upper seat body 11 and a second charging upper seat body 12. The first charging upper seat body 11 and the second charging upper seat body 12 are detachably and fixedly connected. A flexible O-ring 13 is provided at the connection between the first charging upper seat body 11 and the second charging upper seat body 12. The fixing plate 41 is located inside the first charging upper seat body 11, and the connecting plate 42 and the mounting base 45 are both located inside the second charging upper seat body 12. The charging lower seat 2 includes a first charging lower seat body 21 and a second charging lower seat body 22. The first charging lower seat body 21 and the second charging lower seat body 22 are detachably and fixedly connected. The contact head 4 is located inside the second charging lower seat body 22. In summary, when the upper charging base 1 and the lower charging base 2 are connected and the charging head 3 and the contact head 4 are in one-to-one contact, the charging head 3 is retracted into the mounting groove 46, and the second spring 47 is deformed. In addition, the connecting plate 42 and the fixing plate 41 rotate relative to each other, and the first spring 43 is deformed. Through the elastic action of the first spring 43 and the second spring 47, the buffering effect is achieved when the charging head 3 and the contact head 4 are in contact, reducing the wear when the charging head 3 and the contact head 4 are in contact, improving the charging reliability. Moreover, it is also easier for the charging head 3 and the contact head 4 to be pressed tightly together, that is, further improving the charging reliability.
