[0048] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0049] See also Figures 1 to 3 As shown, the embodiment of the present application provides a shared charging device 100, which includes a support shell 1, a first drive mechanism 2, a second drive mechanism 3, a swing arm 4, a locking arm 5, a first reset member 62, and a plurality of power banks 7. Specifically, a plurality of annularly arranged accommodation positions 10 are formed on the support shell 1 (please refer to Figure 4As shown), the upper end and the inner side of the accommodating position 10 are both open, and the power bank 7 is located in each accommodating position 10, wherein the upper end opening is convenient for the power bank 7 to be ejected and returned, and the portion surrounded by each accommodating position 10 is a cavity 12 (that is, the cavity 12 is surrounded by each power bank 7); the first driving mechanism 2 is arranged in the cavity 12 and has a first output shaft 21; the second driving mechanism 3 is arranged in the cavity 12, connected to the first output shaft 21, and has a second output shaft (not shown), and the axial directions of the second output shaft and the first output shaft 21 are perpendicular to each other; the swing arm 4 is arranged in the cavity 12, and the middle part is connected to the second output shaft, so that the rotation of the second output shaft can drive the two ends of the swing arm 4 to swing respectively; the locking arm 5 is rotatably installed in the cavity 12 of the supporting shell 1, and its rotation axis is perpendicular to the first In the axial direction of the output shaft 21, one end of the locking arm 5 can abut (and disengage) with one end of the swing arm 4 after swinging, and one end of the swing arm 4 is provided with a hook 51, which can be engaged with the slot 71 provided on the inner side of the power bank 7; the first reset member 62 is provided in the cavity 12, one end of which is connected to one end of the locking arm 5, and the other end of which is provided on the supporting shell 1, and the first reset member 62 can be compressed when the swing arm 4 swings and presses one end of the locking arm 5. At this time, the hook 51 disengages from the slot 71 (the power bank 7 can pop out), and when the swing arm 4 disengages from the locking arm 5, the compressed first reset member 62 drives the locking arm 5 to return to its original position, and the hook 51 also returns to its original position, and can be engaged with the slot 71 of the power bank 7 again when the power bank 7 is returned next time.

[0050] The working process of the above-mentioned shared charging device 100 is as follows:

[0051] The first driving mechanism 2 rotates, and its first output shaft 21 rotates to a predetermined position, so that both ends of the swing arm 4 can be aligned with the power bank 7; the second driving mechanism 3 rotates, and its second output shaft drives one end of the swing arm 4 to swing downward, and one end of the swing arm 4 presses downward on one end of the locking arm 5, and the hook 51 at the other end of the locking arm 5 is lifted up, and the power bank 7 is freed from the restriction of the hook 51 and pops out from the upper end of the accommodating position 10; the second driving mechanism 3 drives one end of the swing arm 4 to return upward, and the first reset member 62 drives the locking arm 5 to return, and the hook 51 returns.

[0052] The second driving mechanism 3 rotates a certain angle and unlocks another power bank 7 according to the above process, which will not be repeated.

[0053] The user returns the power bank 7 from the opening at the upper end of the accommodation position 10 , and the power bank 7 moves downward until its card slot 71 is matched with the card hook 51 again.

[0054] The shared charging device 100 provided in the embodiment of the present application drives the second driving mechanism 3 and the swing arm 4 to rotate through the first driving mechanism 2 to reach the accommodation position 10 of each power bank 7, and then drives one end of the swing arm 4 to swing downward through the second driving mechanism 3, so as to unlock the locking arm 5 and the power bank 7 at the corresponding accommodation position 10. In this way, the shared charging device 100 of the present application realizes the control of unlocking multiple (more than four, optionally an even number, such as six, eight or more) power banks 7 through the cooperation of the first driving mechanism 2 and the second driving mechanism 3, thereby reducing the number of driving mechanisms in the shared charging device 100, and reducing the volume occupied and cost of the driving mechanisms. In addition, since the two ends of the swing arm 4 can respectively swing to control a locking arm 5 and a power bank 7, the rotation range of the first driving mechanism 2 does not need to reach 360 degrees, which also simplifies the internal wiring setting and more conveniently realizes the initial zero position of the first driving mechanism 2 (see Figure 6 The control of SO is shown in FIG.

[0055] For ease of understanding and description, the "up" and "down" used in the above description and the following description are custom directions. "Up" refers to the direction in which the power bank 7 pops out of the accommodation position 10, and "down" is the opposite. It can be understood that in actual applications, the direction in which the power bank 7 pops out of the accommodation position 10 may not be vertically upward, but may be inclined or horizontal, or in other directions.

[0056] Figure 1 In the embodiment, an outer shell (not shown here) may be provided on the outer periphery of the supporting shell 1 according to the situation, so as to make the overall appearance of the shared charging device 100 smoother and more complete. The outer shell and the supporting shell 1 together constitute a stable basic supporting structure. Of course, it is also possible to omit the outer shell by setting the appearance of the supporting shell 1 so that it constitutes a complete appearance.

[0057] like Figure 1 As shown, a flip cover 11 is provided at the upper opening of each accommodating position 10 , and the cover 11 can be reset and close the upper opening of the accommodating position 10 after the power bank 7 is ejected.

[0058] Among them, see Figure 2 and Figure 3 As shown, the shared charging device 100 also includes a second restoring member 63 , which is disposed at the bottom of the power bank 7 and provides an outward popping force to the power bank 7 via the supporting shell 1 .

[0059] The first driving mechanism 2 and the second driving mechanism 3 may both be motors.

[0060] In this embodiment, the shared charging device 100 further includes a first circuit board 91. Figure 2As shown in FIG. 1 , the first circuit board 91 is electrically connected to the first driving mechanism 2 and the second driving mechanism 3 for supplying power to the first driving mechanism 2 and the second driving mechanism 3 .

[0061] like Figure 2 As shown, in one embodiment, the shared charging device 100 further includes a first support plate 81 and a second support plate 82 ( Figure 2 For the convenience of illustration, the first support plate 81 and the second support plate 82 are separated in the axial direction to a certain extent), and also include a connecting plate 83 (see Figure 2 and Figure 3 As shown in the figure, the first drive mechanism 2, the second drive mechanism 3 and the swing arm 4 are all arranged between the first support plate 81 and the second support plate 82. Among them, the first drive mechanism 2 is fixedly mounted on the first support plate 81, the connecting plate 83 is fixedly mounted on the first output shaft 21 and rotates with the first output shaft 21, and the second drive mechanism 3 is mounted on the connecting plate 83. That is, the connecting plate 83 is used to transfer and connect the first drive mechanism 2 and the second drive mechanism 3. The first support plate 81 and the second support plate 82 are fixedly connected to the support shell 1, and are also substantially part of the basic support structure of the shared charging device 100.

[0062] In addition, optionally, Figure 2 As shown, one end of the connecting plate 83 away from the first driving mechanism 2 is also rotatably connected to the second supporting plate 82. In this way, the first driving mechanism 2 and the connecting plate 83 provide mutual support, so that both can be stably mounted on the first supporting plate 81 and stably rotate.

[0063] The middle portion of the connecting plate 83 may be specifically a bracket-shaped bending structure, and the space inside the bending structure is used to install the second driving mechanism 3 , which can keep the second output shaft and the swing arm 4 at the center position of the cavity 12 .

[0064] In one embodiment, the first support plate 81 is located above the second support plate 82. Figure 2 In other optional embodiments, the first support plate 81 and the first driving mechanism 2 may also be arranged at the bottom, as long as the positional matching relationship between the swing arm 4 and the locking arm 5 is not affected.

[0065] The first circuit board 91 may be optionally disposed on the upper side of the first support plate 81. Figure 2 As shown, that is, the side surface of the first support plate 81 away from the second support plate 82. The wiring (not shown) for connecting the first driving mechanism 2 and the second driving mechanism 3 passes through the first support plate 81.

[0066] The first support plate 81 and the second support plate 82 are arranged relatively spaced apart from each other to provide mounting support for the first driving mechanism 2, the second driving mechanism 3 and the swing arm 4. A plurality of connecting columns 80 are extended relatively from the first support plate 81 and the second support plate 82, see Figure 2 and Figure 5 As shown, the two connecting columns 80 are butted together along the axial direction, so that the first support plate 81 and the second support plate 82 are fixedly butted together and the first driving mechanism 2 and the like are allowed to be arranged between them.

[0067] In the circumferential direction, the space between two adjacent connecting pillars 80 is used to set the locking arm 5, that is, the locking arm 5 is set between two circumferentially adjacent connecting pillars 80. In this way, the first support plate 81 and the second support plate 82 are relatively fixedly installed without affecting the cooperation between the locking arm 5 and the swing arm 4.

[0068] The two connecting columns 80 that are connected to each other along the axial direction can be detachably connected by means of screws, studs or clamping.

[0069] As mentioned above, a plurality of accommodation positions 10 are arranged along the circumferential direction on the support housing 1, and after the first driving mechanism 2 rotates, the swing arm 4 is aligned with the corresponding accommodation position 10 and the power bank 7 therein. Figure 3 and Figure 6 As shown, the shared charging device 100 also includes a plurality of first sensors 86 for sensing and detecting the rotation angle of the first output shaft 21 to indicate where the first driving mechanism 2 is currently rotating to and which two power banks 7 the swing arm 4 is aimed at.

[0070] Further, in this embodiment, see Figure 3 and Figure 6 As shown, the shared charging device 100 also includes a plurality of second sensors 87 for sensing the rotation angle of the second driving mechanism 3 (or the swing of the swing arm 4 or the swing of one end of the locking arm 5) to indicate whether the current locking arm 5 can be unlocked.

[0071] In this embodiment, the shared charging device 100 further includes a second circuit board 92. Figure 2 and Figure 6 As shown, it is electrically connected to the above-mentioned first sensors 86 and second sensors 87 and is also physically connected to supply power to the first sensors 86 and second sensors 87 , provide physical support, and receive trigger signals from the first sensors 86 and second sensors 87 .

[0072] In this embodiment, the first sensor 86 and the second sensor 87 are both through-beam photoelectric sensors, which are disposed on the second circuit board 92. Figure 3As shown, a first sensing column 830 protruding downward is formed on the connecting plate 83, and one end of the locking arm 5 forms a protruding second sensing column 52 on the side away from the swing arm 4 (i.e., the lower side). In the process of the first driving mechanism 2 driving the connecting plate 83 to rotate, the first sensing column 830 reaches between the emitting end and the sensing end of the through-beam photoelectric sensor, thereby triggering the first sensor 86. Moreover, after the swing arm 4 presses one end of the locking arm 5 downward, the second sensing column 52 on the locking arm 5 enters between the emitting end and the sensing end of the through-beam photoelectric sensor, thereby triggering the second sensor 87. The two trigger signals are respectively transmitted to the second circuit board 92.

[0073] In order to facilitate the relative position arrangement between the connecting plate 83 and the locking arm 5 and prevent them from interfering with each other, in this embodiment, the second sensor 87 is arranged radially outside the first sensor 86 .

[0074] Hereinafter, the shared charging device 100 is further described by taking the number of 8 accommodation positions 10 as an example. The 8 power banks 7 are evenly distributed in the circumferential direction, and the angle between two adjacent power banks 7 is 45 degrees.

[0075] See also Figure 3 and Figure 5 As shown, the number of the second sensors 87 corresponds to the number of the locking arms 5, that is, 8, distributed on the same circumference.

[0076] Since the rotation range of the first driving mechanism 2 is less than 360 degrees, the number of the second sensors 87 may be less than 8. Figure 2 and Figure 5 As shown, two limit blocks 84 are provided on the second support plate 82, and two limit surfaces 840 (at Figure 6 The angle between them is 180 degrees, and a stopper 831 (in Figure 3 ). The stopper 831 can respectively abut the two limit surfaces 840 during the rotation process. In this way, the rotation range of the first driving mechanism 2 is 180 degrees. On this basis, the number of the second sensors 87 is two, which are symmetrically arranged on both sides of the midline of the rotation range.

[0077] The two first sensors 86 distinguish the four positions of the second drive mechanism 3 in the following manner:

[0078] like Figure 6As shown, the plane where the two limit surfaces 840 are located is S1, and the plane perpendicular to the plane S1 and bisecting the aforementioned rotation range is S2. The two first sensors 86 are arranged on both sides of the plane S2, and the angles between them and the plane S2 are both 22.5 degrees (the angles between the two first sensors 86 and the two corresponding limit surfaces 840 are both 67.5 degrees). The position of one of the first sensors 86 is defined as the initial zero position SO of the first drive mechanism 2, and the direction in which the first drive mechanism 2 rotates toward the other first sensor 86 is the opposite direction of rotation. Here, it is defined as Figure 6 The position of the first sensor 86 on the left side is the initial zero position SO of the first driving mechanism 2, and the first driving mechanism 2 deflects to the right to rotate in the opposite direction.

[0079] The first driving mechanism 2 is powered on and is located at the initial zero position SO, and the swing arm 4 is aligned with the two locking arms 5. At this time, the second driving mechanism 3 can rotate and unlock the corresponding two power banks 7 (the first and fifth respectively).

[0080] Then, after the first driving mechanism 2 rotates 45 degrees, the swing arm 4 is aimed at the other two power banks 7 (the 2nd and 6th respectively). If the third circuit board 93 detects the signal of the first sensor 86 at this time, it means that the first driving mechanism 2 is reversed; based on this reversal, the first driving mechanism 2 continues to rotate 45 degrees, and the swing arm 4 is aimed at the other two power banks 7 (the 3rd and 7th respectively). At this time, the second circuit board 92 cannot detect the signal of the first sensor 86, indicating that the first driving mechanism 2 has reached the limit position of the reversal direction, and then, it can return to the initial zero position SO by rotating forward 112.5 degrees.

[0081] Conversely, starting from the initial zero position, after the first drive mechanism 2 rotates 45 degrees, the swing arm 4 is aligned with the other two power banks 7 (the 4th and 8th respectively). At this time, the third circuit board 93 cannot detect the signal of the first sensor 86, which means that the first drive mechanism 2 is rotating forward and has reached the limit position in the forward direction. Then, it can return to the initial zero position SO by reversing 67.5 degrees.

[0082] In this way, the first driving mechanism 2 can accurately determine the positions of the eight power banks 7 by means of the two first sensors 86 and the two limit blocks 84 .

[0083] Figure 6 In the embodiment, the first sensor 86 is located on the angular bisector of two adjacent second sensors 87, which is based on the arrangement on the limited area of ​​the second circuit board 92. In other optional embodiments, the first sensor 86 and the second sensor 87 can be aligned in the radial direction or spaced at other angles as needed.

[0084] In other optional embodiments, the number of power banks 7 may be other numbers, and correspondingly, the number and arrangement of the first sensors 86 may be other numbers.

[0085] See also Figure 5 As shown, in one embodiment, a plurality of vertical baffles 85 are provided on the upper surface of the second support plate 82, and a horizontally penetrating shaft hole 850 is provided on the baffle 85. The rotating shaft 53 passes through the shaft hole 850 and connects the locking arm 5 and the baffle 85, so that the locking arm 5 is rotatably mounted on the baffle 85.

[0086] Optionally, in order to further stabilize the installation of the locking arms 5 on the second support plate 82, an oblique connecting rod 61 is provided between the sides of each two locking arms 5 that are close to each other, see Figure 5 As shown in , the rotating shaft 53 also passes through the end surface of the oblique connecting rod 61. In this way, the two sides of the locking arm 5 are supported and fixed by the baffle 85 and the oblique connecting rod 61 respectively, which can ensure that the locking arm 5 swings stably along the vertical plane.

[0087] like Figure 5 As shown, in the middle of one embodiment, a plurality of through holes 860 are provided on the second support plate 82, and after the first reset member 62 passes through the through holes 860, its lower end can abut against the inner wall of the aforementioned outer shell. It can be understood that if the outer shell can be omitted, the lower end of the first reset member 62 can be directly connected to the second support plate 82 or the support shell 1.

[0088] Please continue reading Figure 2 As shown, in one embodiment, the shared charging device 100 further includes a third circuit board 93, which is located below each accommodation position 10, and the lower end of the accommodation position 10 is also open. A third sensor and a charging connector 95 are provided on the third circuit board 93. When the power bank 7 is located in the accommodation position 10, the third sensor can be triggered and connected to the charging connector 95. The third sensor is used to send a micro signal to the third circuit board 93, indicating that the power bank 7 is returned to its place at this time, and the charging connector 95 is used to charge the power bank 7. The third sensor can be a micro switch 94, or other types of sensors.

[0089] The third circuit board 93 is annular and is arranged around the swing arm 4 and the connecting column 80. The purpose of such arrangement is to match the height relationship between the third sensor and the charging connector 95.

[0090] In addition, please refer to Figure 2 and Figure 5As shown, the middle portion of the second support plate 82 for setting the limit block 84 protrudes relatively and passes through the second circuit board 92. In this way, it is convenient for the first sensing column 830 to cooperate with the first sensor 86, the second sensing column 52 to cooperate with the second sensor 87, and the rotational cooperation between the limit block 84 and the stop block 831 (the stop block 831 does not need to pass through the second circuit board 92).

[0091] A certain electrical connection relationship can be formed between the first circuit board 91, the second circuit board 92 and the third circuit board 93. For example, the first circuit board 91 serves as the main circuit board, the second circuit board 92 and the third circuit board 93 are both connected to the first circuit board 91, the first circuit board 91 is also connected to an external power supply, and the first circuit board 91 is also connected to the control background communication through a remote connection module, etc.
