Description

Technical Field

[0001] The utility model belongs to the technical field of electronic products, and particularly relates to a 360-degree charging structure and device based on a single-turn PogoPin. Background Art

[0002] PogoPin spring pins are a type of hardware component that serves as a connector for current and signal transmission in electronic devices. PogoPins have the advantages of small size, strong current-carrying capacity, good contact stability, beautiful appearance, and reliable performance. Therefore, they are widely used in the signal transmission and charging function designs of various electronic products.

[0003] In the charging function based on PogoPins, under the existing technology, two conventional PogoPin structure arrangements are adopted. One is that the PogoPins are set at fixed positions and divided into two groups. One group is used to output positive voltage, and the other group is used to output negative voltage. When the power collection device is electrically connected to the power supply device for charging, it is necessary to ensure that the fitting angles are consistent, that is, one electrode plate of the power collection device needs to be completely opposite to the positive PogoPin area, and the other electrode plate needs to be completely opposite to the negative PogoPin area. Therefore, when charging is achieved in this way, if there is an offset in the docking angle between the power collection part and the power supply part, the charging function cannot be realized, making the operation extremely inconvenient and the charging efficiency low.

[0004] To solve the drawbacks of the above PogoPin structure, another PogoPin arrangement method has been proposed under the existing technology. For example, in CN208508175U, a 360-degree magnetic electrical connection device is disclosed, which includes a magnetic male head and a transmission device. The magnetic male head is provided with an electrode contact and a plurality of contact pieces arranged on different concentric circles with the electrode contact as the center. The transmission device is provided with a plurality of bent metal pieces corresponding to the contact pieces. That is, under the existing technology, to achieve the 360-degree plugging function, at least 2 circles of PogoPins are arranged in the radial direction of the power supply part. The PogoPin circles at different radial positions represent different voltage output polarities. When charging is achieved in this way, the occupied volume of the power collection part and the power supply part is too large, especially it will occupy the central area of the power collection part, resulting in the inability of the PogoPin charging structure to coexist with the Type-C interface. Summary of the Utility Model

[0005] The utility model aims to provide a 360-degree charging structure and device based on a single-turn PogoPin to solve the technical problems that in the existing technology, the single-turn PogoPin structure cannot achieve charging between the power collection part and the power supply part at any angle, while the double-turn PogoPin structure occupies too large a volume.

[0006] To solve the above problems, the technical solution of the present utility model is: a 360-degree charging structure based on a single-turn PogoPin, including a current collection part and a power supply part;

[0008] The power supply part includes a detection thimble and output thimbles. The output thimbles are used to output positive and negative voltages.

[0009] The current collection part and the power supply part are configured such that when the electrode sheet and the thimble are connected at any angle, if the detection thimble and the third output thimble are short-circuited, the first voltages output by the first output thimble and the third output thimble have the same polarity, the second voltages output by the second output thimble and the fourth output thimble have the same polarity, and the second voltage is opposite in polarity to the first voltage; if the detection thimble and the second output thimble are short-circuited, or the detection thimble is suspended, the third voltages output by the first output thimble and the second output thimble have the same polarity, the fourth voltages output by the third output thimble and the fourth output thimble have the same polarity, and the fourth voltage is opposite in polarity to the third voltage.

[0010] Preferably, the arc lengths of the intervals between the detection thimble and the second output thimble and the third output thimble are equal.

[0011] Preferably, there is a second distance between the first output thimble and the second output thimble, and a third distance between the first output thimble and the third output thimble. The second distance is less than the third distance.

[0012] Preferably, the second distance is greater than the first distance.

[0013] Preferably, there is a fourth distance between the detection thimble and the first output thimble. The fourth distance is less than the first distance.

[0014] Preferably, the thimble heights of the detection thimble, the second output thimble, and the third output thimble are set to a first height, and the thimble heights of the first output thimble and the fourth output thimble are set to a second height, where the first height is greater than the second height.

[0015] Based on the same concept, the present utility model also provides a 360-degree charging device based on a single-turn PogoPin, which adopts the 360-degree charging structure based on a single-turn PogoPin described in any one of the above, and includes a current collecting device and a power supplying device;

[0016] One end of the current collecting device is fixedly provided with a current collecting part, and one end of the power supplying device is fixedly provided with a power supplying part.

Among them, the detection thimble and each output thimble are arranged in a special layout manner. When the power collection part and the power supply part are conductively connected, if the detection thimble is short-circuited with the third output thimble, the first output thimble and the third output thimble output voltages of the same polarity, and the second output thimble and the fourth output thimble output another voltage of the same polarity. If the detection thimble is short-circuited with the second output thimble, or the detection thimble is suspended, the first output thimble and the second output thimble output voltages of the same polarity, and the third output thimble and the fourth output thimble output another voltage of the same polarity. It can be seen from this that in the present utility model, regardless of the angle at which the power collection part and the power supply part are conductively connected, the output thimbles can adaptively adjust the output voltage polarity, so that one electrode sheet is connected to the positive electrode and the other electrode sheet is connected to the negative electrode, improving the charging portability. At the same time, both the PogoPin structure and the electrode sheet structure are single-loop designs, greatly reducing the volume occupied in the power collection part and the power supply part.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further details a 360-degree charging structure and device based on a single-loop PogoPin proposed by the present utility model in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present utility model will be clearer according to the following description and the claims.

[0028] First Embodiment

[0029] Refer to Figures 1 to 3, this embodiment provides a 360-degree charging structure based on a single-turn PogoPin, including a current collection part 7 and a power supply part 1. Through the design of the single-turn electrode sheet in the current collection part 7 and the single-turn PogoPin structure in the power supply part 1, the function of realizing charging can be achieved with any 360° angle connection between the current collection part 7 and the power supply part 1.

[0030] Specifically, referring to Figure 2 , the current collection part 7 includes a first electrode sheet 8 and a second electrode sheet 9 with a semi-circular structure. The first electrode sheet 8 and the second electrode sheet 9 are respectively arranged in the circumferential edge area of the current collection part 7, and the two are symmetrically arranged along the central point of the current collection part 7. It can be understood that the first electrode sheet 8 and the second electrode sheet 9 are circumferentially arranged along a single-turn trajectory in the current collection part 7 with a circular cross-section. Further, there is a fixed distance between the two end parts of the first electrode sheet 8 and the two opposite end parts of the second electrode sheet 9. This distance is set as the first distance. In this embodiment, the current collection part 7 is used to establish physical contact with the corresponding contacts of the power supply part 1, thereby creating a current path and realizing power transmission, that is, the first electrode sheet 8 and the second electrode sheet 9 are respectively used to connect the positive and negative poles of the power supply.

[0031] Referring to Figure 1 , the power supply part 1 includes a detection thimble 2 and a plurality of output thimbles. The output thimbles specifically include a first output thimble 3, a second output thimble 4, a third output thimble 5, and a fourth output thimble 6. In this embodiment, the plurality of output thimbles can be grouped in pairs to form a total of two output thimble groups, which are respectively used to output positive and negative voltages.

[0032] Among them, the detection thimble 2, the first output thimble 3, the second output thimble 4, the third output thimble 5, and the fourth output thimble 6 are respectively circumferentially arranged in the edge area of the power supply part 1 and do not touch each other. It can be understood that the detection thimble 2, the first output thimble 3, the second output thimble 4, the third output thimble 5, and the fourth output thimble 6 are also circumferentially arranged along a single-turn trajectory in the power supply part 1 with a circular cross-section. Further, the first output thimble 3 and the fourth output thimble 6 are symmetrically arranged along the central point of the power supply part 1, the second output thimble 4 and the third output thimble 5 are symmetrically arranged along the central point of the power supply part 1, the detection thimble 2 is arranged between the first output thimble 3 and the third output thimble 5, and preferably, the arc lengths between the detection thimble 2 and the second output thimble 4 and the third output thimble 5 are equal, that is, the three points of the detection thimble 2, the second output thimble 4, and the third output thimble 5 can be understood as an isosceles right triangle structure.

[0033] Further, there is a spacing between the first output thimble 3 and the second output thimble 4 (the third output thimble 5 and the fourth output thimble 6). This spacing is set as the second spacing. There is also a spacing between the first output thimble 3 and the third output thimble 5 (the second output thimble 4 and the fourth output thimble 6), which is set as the third spacing. In this embodiment, the second spacing is less than the third spacing. It can be understood that the four points of the first output thimble 3, the second output thimble 4, the third output thimble 5, and the fourth output thimble 6 form a rectangular structure centered on the center of the power receiving part 1. At the same time, the second spacing is greater than the first spacing, that is, the spacing between the first output thimble 3 and the second output thimble 4 (the third output thimble 5 and the fourth output thimble 6) is greater than the spacing between the ends of the first electrode piece 8 and the second electrode piece 9.

[0034] Further, there is a spacing between the detection thimble 2 and the first output thimble 3. This spacing is set as the fourth spacing. The fourth spacing is less than the first spacing, that is, the spacing between the detection thimble 2 and the first output thimble 3 is less than the spacing between the ends of the first electrode piece 8 and the second electrode piece 9.

[0035] See Figure 3 , based on the electrode piece of the current collecting part 7 and the PogoPin structure of the power receiving part 1 as set above. In this embodiment, the current collecting part 7 and the power receiving part 1 are configured such that when the electrode piece is electrically connected to the thimble at any angle, if the detection thimble 2 is short-circuited with the third output thimble 5, the first voltage polarities output by the first output thimble 3 and the third output thimble 5 are the same, the second voltage polarities output by the second output thimble 4 and the fourth output thimble 6 are the same, and the second voltage is opposite in polarity to the first voltage. If the detection thimble 2 is short-circuited with the second output thimble 4, or the detection thimble 2 is floating, the third voltage polarities output by the first output thimble 3 and the second output thimble 4 are the same, the fourth voltage polarities output by the third output thimble 5 and the fourth output thimble 6 are the same, and the fourth voltage is opposite in polarity to the third voltage. It should be noted that the detection thimble 2 being floating means that neither the first electrode piece 8 nor the second electrode piece 9 is in contact with the detection electrode, or only one of the first electrode piece 8 and the second electrode piece 9 realizes short-circuit detection between the detection thimble 2 and the first output thimble 3, that is, the detection thimble 2 is not short-circuited with the third output thimble 5 and is not short-circuited with the second output thimble 4.

[0036] In summary, a 360-degree charging structure based on a single-turn PogoPin provided in this embodiment utilizes the special structural settings of the current collection part 7 and the power supply part 1, as well as the logical control relationship, to construct a structure that can achieve the charging function at 360°. When the current collection part 7 and the power supply part 1 are connected at any angle, there will only be three short-circuit situations between the electrode plate and the PogoPin, namely, the detection pin 2 is short-circuited with the third output pin 5, the detection pin 2 is short-circuited with the second output pin 4, and the detection pin 2 is suspended. Based on these three different short-circuit situations, the actual connection relationship between the detection pin 2 and the first output pin 3, the second output pin 4, the third output pin 5, and the fourth output pin 6 can be specifically determined. Among them, at least one of the first electrode plate 8 and the second electrode plate 9 will be connected to a relatively arranged output pin. Subsequently, the PogoPin will adaptively adjust the polarity of its own voltage output based on the logic circuit design, so that the first electrode plate 8 and the second electrode plate 9 will receive voltages of different polarities respectively, realizing the function of the power supply part 1 supplying power to the current collection part 7.

[0037] Preferably, in this embodiment, there are differences in the set heights of the detection pin 2 and each output pin. The pin heights of the detection pin 2, the second output pin 4, and the third output pin 5 are uniformly set to a first height, and the pin heights of the first output pin 3 and the fourth output pin 6 are uniformly set to a second height. The first height is greater than the second height, so that during the connection process of the current collection part 7 and the power supply part 1, the logic circuit can detect the angular state of the current electrode plate relative to the pin in advance, and then quickly respond and adjust the output voltage polarities of the first output pin 3 and the fourth output pin 6.

[0038] Second Embodiment

[0039] Based on the same concept, this embodiment provides a 360-degree charging device based on a single-turn PogoPin, which is made of a 360-degree charging structure based on a single-turn PogoPin, and includes a current collection device and a power supply device. The current collection device can be understood as relying on a built-in rechargeable battery to store electrical energy through charging for use in the absence of a direct power source. The power supply device can be understood as a power output device that can output electrical energy. In this embodiment, the current collection device and the power supply device are adapted to realize the function of the power supply device supplying energy to the current collection device.

[0040] Specifically, a current collection part 7 is fixedly provided at one end of the current collection device, and a power supply part 1 is fixedly provided at one end of the power supply device. Based on the 360° connectable characteristic of the current collection part 7 and the power supply part 1, when the current collection device and the power supply device are connected at any angle, the power supply device can supply power to the current collection device.

[0041] The power supply device is provided with a PCB board. The detection thimble 2, the first output thimble 3, the second output thimble 4, the third output thimble 5 and the fourth output thimble 6 in the power supply unit 1 are respectively welded and fixed at specific positions on the PCB. A logic control circuit and components are engraved on the PCB board. Refer to Figure 4 As shown, in this embodiment, an MOS transistor is used as a control switch. The voltage polarity of the detection thimble 2 can control the MOS transistor to achieve conduction or cut-off, and then adjust the voltage polarity of the corresponding output thimble. Specifically, taking Figure 4 the positive and negative power outputs and the arrangement of the output thimbles as an example, the output voltage polarity states of the second output thimble 4 and the third output thimble 5 remain unchanged, that is, the second output thimble 4 always maintains a positive output, and the third output thimble 5 always maintains a negative output. When the detection thimble 2 is short-circuited with the second output thimble 4 or the third output thimble 5, its polarity changes accordingly. Based on the voltage polarity of the detection thimble 2, the connection between the first output thimble 3 and / or the fourth output thimble 6 and the corresponding power output can be adjusted by controlling the conduction or cut-off of the MOS transistor, that is, the function of adjusting the output voltage polarity of the first output thimble 3 and / or the fourth output thimble 6 is achieved. It should be noted that Figure 4 the positive and negative output directions of the power supply in

[0042] is only one implementation manner. When the positive and negative output directions of the power supply are adjusted, the logic circuit function can still be normally realized, and only the output voltage polarity of the second output thimble 4 or the third output thimble 5 is adjusted accordingly.

[0043] Preferably, one end of the current collection part 7 of the current collection device is in a columnar structure. The power supply device is provided with a receiving cavity at one end of the power supply part 1. The power supply part 1 is arranged at the bottom end of the receiving cavity. When the current collection device and the power supply device need to be conductively connected for charging, one end of the current collection part 7 of the current collection device can be inserted into the receiving cavity of the power supply device, so that when the current collection part 7 is conductively connected to the power supply part 1, the current collection device and the power supply device maintain a stable connection posture to make the charging effect stable.

[0044] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and their equivalent technologies, they still fall within the protection scope of the present invention.
