Description

Technical Field

[0001] This disclosure relates to the field of electronic devices, and more specifically, to a bidirectional rotary joint mechanism and a mobile power supply. Background Technology

[0002] External power devices for mobile phones or electronic devices are generally connected to the phone's interface via a charging port. A common example is a power bank, which has a built-in connector that connects to the phone for charging, reducing the inconvenience of carrying and using data cables.

[0003] Considering that fixed connectors are prone to collisions that could damage the electrical connectors, existing technologies have designed connector structures that can rotate and change posture, allowing them to be stored inside the power bank when not in use. For example, the power bank shown in patent CN202320650326.3 has a rotating base and a storage slot, allowing the rotating connector to switch between two postures: vertical insertion and horizontal storage. However, since this connector only has one usage posture, it cannot adapt to the needs of electronic devices to switch between different usage postures when charging mobile phones or other electronic devices, and cannot meet the user's needs for multiple usage scenarios.

[0004] In view of this, this design proposes a bidirectional rotatable connector mechanism and a mobile power supply with the mechanism built in. The connector mechanism can change into various postures during use, making it easier to adjust and adapt to the usage needs of mobile phones or electronic devices.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this disclosure is to provide a bidirectional rotary joint mechanism and a mobile power supply, thereby overcoming, at least to some extent, one or more problems caused by the limitations and defects of related technologies.

[0007] According to one aspect of this disclosure, a bidirectional rotary joint mechanism is provided, comprising:

[0008] The mounting base is an integral or independent structure with the outer shell. It has interconnected mounting slots and storage slots. The mounting slots have a ring track on their walls and a rotation point on the ring track.

[0009] The connector includes an integral connector body, a base, and contacts. The contacts are provided on the base and are installed in the mounting groove. The contacts cooperate with the annular track to achieve horizontal rotation. The contacts slide along the annular track to the rotation point and rotate vertically at the rotation point to switch the connector mechanism between the plug-in state and the storage state.

[0010] In one exemplary embodiment of this disclosure, a support point is also provided on the annular track, and when the contact slides to the support point, the connector mechanism can establish another insertion state.

[0011] In one exemplary embodiment of this disclosure, the annular track is an open-loop track with an annular groove structure, the rotation point is a first rotation stop hole located at one end of the annular track, and the support point is a second rotation stop hole located at the other end of the annular track.

[0012] In one exemplary embodiment of this disclosure, the annular track has an interruption notch in the middle, and there are three contact points on the base, with at least two contact points always sliding in contact with the annular track.

[0013] In one exemplary embodiment of this disclosure, the substrate is a spherical structure, and correspondingly, the mounting groove has a spherical groove wall. The rotation center of the annular track coincides with the spherical center of the mounting groove, and the rotation centers of the three contacts are all located on the horizontal radial surface of the substrate.

[0014] In one exemplary embodiment of this disclosure, a wire harness is provided on the bottom circumferential surface of the substrate, and a clearance hole is provided at the bottom of the mounting groove for accommodating the wire harness; the wire harness is offset to one side of the center of rotation of the substrate, and the inner edge of the clearance hole has a first clearance notch, a second clearance notch and a third clearance notch, which correspond to another insertion state, an insertion state and a storage state, respectively.

[0015] In one exemplary embodiment of this disclosure, a buffer hole is also provided at the bottom of the mounting groove, extending vertically to the second rotation stop hole.

[0016] In one exemplary embodiment of this disclosure, the mounting base includes a first housing and a second housing, which together form a mounting groove and a receiving groove. The first housing and the second housing are provided with mutually cooperating limiting structures for constructing a force-bearing community and limiting the assembly of the two.

[0017] A portable power bank has a built-in bidirectional rotatable connector mechanism, and a pressure-fitting structure is provided inside the power bank housing for detachable installation on a mounting base.

[0018] In one exemplary embodiment of this disclosure, when the connector mechanism is in another plug-in state, the mobile power supply constructs an angular support for the electrical device with the connector as a fulcrum.

[0019] An exemplary embodiment of this disclosure provides a bidirectional rotatable connector mechanism and a mobile power supply. The connector mechanism has an annular slide and a rotation point in its mounting groove. The contact has a sliding degree of freedom along the annular slide and a rotational degree of freedom at the rotation point. With the storage groove provided in the connector mechanism, the connector mechanism has the ability to vertically rotate for storage and horizontally rotate to adjust the insertion angle. This not only helps to protect the connector mechanism but also makes it adaptable to more usage environments. The connector mechanism also has the characteristics of simple structure, low cost, and good operability.

[0020] Correspondingly, the power bank with the built-in connector mechanism can adapt to changes in the state of the electrical equipment and its usage scenario. In the second plug-in state, the power bank can be used as a mobile phone stand while charging.

[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0042] In this example embodiment, a bidirectional rotatable connector mechanism is provided for connecting external electrical components and electronic devices. This embodiment uses the connection between a power bank 100 and a mobile phone as an example. Figure 1-12 As shown, it includes a mounting base and a connector 220, wherein,

[0043] Refer again Figure 10The mounting base serves as the carrier of the connector 220. It can be an integral structure with the outer shell of the power bank 100, or it can be press-fitted into the power bank shell as an independent structure. The mounting base can be an integral structure or a modular structure assembled from the first shell 210 and the second shell 230. In this embodiment, a modular structure is preferred. The assembled mounting base can form an interconnected mounting groove 201 and a storage groove 202. The first annular track 212 on the first shell 210 and the second annular track 231 on the second shell 230 are combined to form an annular track in the mounting groove 201. The first mounting base provides the connector 220 with a horizontal rotational degree of freedom through the annular track set on the groove wall of the mounting groove 201. A rotation point is set on the annular track, and the connector 220 can achieve a vertical rotational degree of freedom at this rotation point. Thus, the connector 220 obtains a bidirectional rotation function.

[0044] The connector 220 includes an integral connector body 221, a base 222, and contacts. The connector body 221 is a connector 220 encapsulation structure adapted to the mobile phone interface. The base 222 is located at the root of the connector body 221 and is installed in the mounting groove 201. The base 222 slides and engages with the annular track through the contacts on it to achieve horizontal rotation, which is used to adjust the different positions of the mobile power supply 100 in the plugged-in state so as to adapt to various usage environments. The contacts are at the rotation points of the annular track and can cooperate with the rotation structure at the rotation points to achieve vertical rotation. The vertical rotation is used to switch the first plugged-in state and the storage state of the connector mechanism 200.

[0045] By setting support points on the circular track, the connector mechanism 200 can obtain a certain support force at the support points, maintaining a relatively stable second insertion state at that point. The rotation point and the support point are separated by an angle of 90°.

[0046] Specifically, such as Figures 10-12 As shown, the annular track is an open-loop track with an annular groove structure. The contact point is designed with cylindrical protrusions. The rotation point is the first rotation stop hole 232 located at one end of the annular track. The contact point rotates and engages with the first rotation stop hole 232. When the first contact point 223 slides along the annular track to the first rotation stop hole 232, it is stopped. Under the rotatable support of the first rotation stop hole 232, the connector 220 can rotate vertically. At the rotation point, the front of the connector 220 faces the storage groove 202. After vertical rotation, it can be completely embedded in the storage groove 202. Similarly, the support point is the second rotation stop hole 233 located at the other end of the annular track. Under the stop of the second contact point 224 in the second rotation stop hole 233, the connector mechanism 200 can obtain a support force perpendicular to the stop direction.

[0047] In one exemplary embodiment of this disclosure, the connector mechanism 200 adopts a thin and light design. The receiving groove 202 and the mounting groove 201 are located on the same level. Therefore, the annular track is located on the receiving channel of the receiving groove 202. To make way for the receiving channel, the middle of the annular track is interrupted by the opening of the receiving groove 202 to form an interruption gap. Thus, in order to ensure the stable support and rotational guidance of the base 222, three contacts are provided on the base 222, namely the first contact 223, the second contact 224, and the third contact 225. In the rotational path of the base 222, especially during the process of the base 222 rotating from the rotation point to the support point, before the first contact 223 falls into the interruption gap, the third contact 225 should slide into the first annular track 212. There are always at least two contacts sliding in contact with the annular track. Figure 9 As shown, since the rotation point and the support point are separated by an angle of 90°, the three contacts are located at the same height, and the interval angle between adjacent contacts is 90°.

[0048] In one exemplary embodiment of this disclosure, in order to further provide guidance and stable support for horizontal and vertical rotation, the base 222 adopts a spherical structure design. Accordingly, the mounting groove 201 has a spherical groove wall, the rotation center of the annular track coincides with the spherical center of the mounting groove 201, and the rotation centers of the three contacts are all located on the horizontal radial surface of the base 222.

[0049] In an exemplary embodiment of this disclosure, the signal lines of the connector 220 are combined to form a wire harness 226, which is led out from the bottom circumferential surface of the base 222. In order to make room for the wire harness 226 during the bidirectional rotation of the connector mechanism 200, a clearance hole 204 is provided at the bottom of the mounting groove 201.

[0050] Specifically, Figure 6 and Figure 8 As shown, the wire harness 226 is offset to one side of the rotation center of the base 222. In order to meet the requirements of the bidirectional rotational movement area of ​​the wire harness 226, and to avoid interference and wear of the wire harness 226 caused by the shaking of the connector mechanism 200 in the three states, the inner edge of the clearance hole 204 has a first clearance notch 204a, a second clearance notch 204b, and a third clearance notch 204c, which correspond to the second insertion state, the first insertion state, and the storage state, respectively. The second clearance notch 204b and the third clearance notch 204c are arranged opposite to each other, and the interval angle between the first insertion state and the second insertion state is 90°. The first clearance notch 204a is located between the second clearance notch 204b and the third clearance notch 204c, and it is smoothly connected to the latter two.

[0051] In one exemplary embodiment of this disclosure, such as Figure 4As shown, the support points can be used to build corner supports for the mobile phone. In order to prevent the impact force from damaging the contacts of the connector 220, a buffer hole 203 is also provided at the bottom of the mounting groove 201, which extends vertically to the second rotation stop hole 233. The contacts slide into the buffer hole 203 to unload the impact and protect the connector mechanism 200 and the mobile phone interface.

[0052] In one exemplary embodiment of this disclosure, the first housing 210 and the second housing 230 are provided with mutually cooperating limiting structures, such as... Figure 5 , Figure 7 , Figure 11 and Figure 12 As shown, the limiting structure includes an L-shaped insertion groove 211 on the first housing 210, an insertion body 234 on the second housing 230, a groove tail plate 213 on the first housing 210, and an L-shaped limiting plate 235 on the second housing 230. The insertion body 234 cooperates with the insertion groove 211, and the limiting plate 235 cooperates with the side of the groove tail plate 213 to form a force-bearing community and limit the assembly of the two.

[0053] This example embodiment also provides a portable power bank, such as... Figures 1-4 As shown, the power bank 100 has several mounting structures inside its casing, including common positioning posts, plug-in pieces, connecting ears, etc. The aforementioned bidirectional rotatable connector mechanism 200 is built into the detachable positioning and press-fit mounting base.

[0054] In one exemplary embodiment of this disclosure, when the connector mechanism 200 is in the second plug-in state, the power bank 100 forms an angle support for the power device with the connector 220 as the fulcrum. Thus, when charging, the power bank 100 can also be used as a stand for a mobile phone when the connector mechanism 200 is rotated horizontally to the second plug-in state.
