[0032] In recent years, with the widespread use of electronic devices, the application scenarios of charging devices have increased. Existing charging devices with foldable prongs usually reduce the risk of electric shock caused by contact between the external fine metal wires and the metal at the base of the prongs by reducing the gap at the connection between the base of the prongs and the housing. However, this method cannot isolate the metal at the base of the prongs from the outside world, and the insulation protection effect is relatively poor and needs to be improved.

[0033] Therefore, this application provides a charging device with good insulation protection.

[0034] Below, refer to Figures 1 to 5 Some embodiments of this application will be described in detail.

[0035] Figure 1 Exploded views of charging devices provided in some embodiments of this application; Figure 2 This is a schematic diagram of the structure of the charging device in the extended state provided in some embodiments of this application; Figure 3 A schematic diagram of the hidden portion of the pin assembly of the charging device provided in some embodiments of this application; Figure 4 A schematic diagram of the retracted state of the plug assembly and insulating shield of the charging device provided in some embodiments of this application; Figure 5 A cross-sectional view of a charging device provided for some embodiments of this application.

[0036] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figure 1 and Figure 2 In the illustrated embodiments, the first direction, the second direction, and the third direction are given as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figure 1 and Figure 2 As shown by the arrows in the diagram, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction.

[0037] This application provides a charging device, such as Figures 1 to 5 As shown, the charging device includes a housing 1, a plug assembly, an electrical connection assembly 3, and an insulating shield 4. The housing 1 has a receiving groove 10 recessed into an inner cavity 13 along a first direction X, communicating with the inner cavity 13. One end of the receiving groove 10 extends to the outer surface of the housing 1 along a second direction Y, forming a first opening 102. The plug assembly includes a plug 2, one end of which is an adapter 201, and the other end is a plug-in terminal 202 for connecting to a power source. The plug 2 is rotatably connected to the housing 1 via the adapter 201. At least a portion of the electrical connection assembly 3 is disposed within the inner cavity 13 and connected to the adapter 201. 1. Electrical connection; Insulating shield 4 is provided in housing 1; The insulating shield 4 is configured to switch between an extended state and a retracted state. In the extended state, at least a portion of the insulating shield 4 is located in the receiving groove 10 and divides the receiving groove 10 into two first and second sub-grooves arranged along the second direction Y. A first opening 102 is provided in the first sub-grooves, and the pin 2 passes through the second sub-grooves along the first direction X. In the retracted state, the insulating shield 4 exits the receiving groove 10, and the second direction Y intersects the first direction X.

[0038] For example, the pin 2 passes through the second slot along the first direction X, and the wall of the second slot forms a communication port 101 that communicates with the inner cavity 13. The adapter 201 extends into the inner cavity 13 through the communication port 101 and connects with the electrical connection assembly 3.

[0039] For example, in the retracted state, all pins 2 are housed in the receiving slot 10, which can effectively store and protect the pins 2.

[0040] For example, an abutment mechanism that can push the plug 2 to rotate outward from the receiving groove 10 can be provided on the bottom wall of the receiving groove 10, or a rotating device that can drive the plug 2 to rotate can be provided on the adapter end 201 of the plug 2, etc., as long as it can be made to rotate outward by applying force to the plug 2.

[0041] For example, in the retracted state, part of the pin 2 is housed in the receiving groove 10, and part of the pin 2 extends out of the receiving groove 10. When in use, the extended part of the pin 2 can be engaged for easy use.

[0042] For example, the pin 2 is elongated, the receiving groove 10 is elongated, and the length direction of the receiving groove 10 is consistent with the second direction Y.

[0043] For example, the housing 1 includes a bottom shell 11 and a top cover 12, with the top cover 12 closing the bottom shell 11 to form an inner cavity 13.

[0044] For example, the charging device also includes a circuit board 6 housed in the cavity 13 of the housing 1, the circuit board 6 being electrically connected to the electrical connection assembly 3.

[0045] The housing 1 has a receiving groove 10 recessed in the inner cavity 13 along the first direction X toward the housing 1. The receiving groove 10 communicates with the inner cavity 13. One end of the receiving groove 10 extends to the outer surface of the housing 1 along the second direction Y and forms a first opening 102. The plug 2 is rotatably connected to the housing 1 through the adapter 201. At least a portion of the electrical connection assembly 3 is disposed in the inner cavity 13 and is electrically connected to the adapter 201. The insulating shield 4 is disposed on the housing 1. The insulating shield 4 is configured to switch between an extended state and a retracted state. When the charging device is needed, the insulating shield 4 is in the extended state, with at least a portion of the insulating shield 4 located within the receiving slot 10, dividing the receiving slot 10 into two sub-slots arranged along the second direction Y. A first opening 102 is provided in the first sub-slot, and the plug 2 passes through the second sub-slot along the first direction X. The plug end 202 is inserted into an external power source to charge the device to be charged connected to the charging device. When not in use, the insulating shield 4 is switched to the retracted state, and the insulating shield 4 exits the receiving slot 10, allowing more of the plug 2 to be accommodated in the receiving slot 10, thereby reducing space occupation and making the charging device easy to carry. In addition, the insulating shield 4 is provided on the housing 1. In the extended state, at least a portion of the insulating shield 4 is located in the receiving groove 10 and divides the receiving groove 10 into a first sub-groove and a second sub-groove. The pin 2 passes through the second sub-groove. Thus, along the second direction Y, the insulating shield 4 blocks the adapter end 201 of the pin 2 passing through the second sub-groove. Therefore, the probability of external conductive objects making electrical contact with the adapter end 201 is reduced, thereby improving the insulation protection effect.

[0046] In some embodiments of this application, in the retracted state, the pin 2 extends along the second direction Y and is at least partially received in the receiving groove 10, and the length of the portion of the pin 2 extending along the second direction Y that is located in the receiving groove 10 is greater than the length of the portion of the pin 2 extending along the first direction X that is located in the receiving groove 10.

[0047] When the insulating shield 4 is in the retracted state, the plug 2 is at least partially housed in the receiving groove 10. The plug 2 extends along the second direction Y, and the length of the portion of the plug 2 extending along the second direction Y that is located in the receiving groove 10 is greater than the length of the portion of the plug 2 extending along the first direction X that is located in the receiving groove 10. As a result, more of the plug 2 can be housed in the receiving groove 10 to reduce space occupation and make the charging device easy to carry.

[0048] In some embodiments of this application, such as Figures 1 to 3As shown, the receiving groove 10 has a first limiting surface 103 facing the first opening 102 at one end along the second direction Y. In the extended state, the plug 2 abuts against the first limiting surface 103, and the insulating shield 4 is located on the side of the plug 2 facing the first opening 102.

[0049] For example, in the retracted state, at least a portion of the plug 2 along the second direction Y is received in the receiving groove 10, and a portion of the plug end 202 extends outward through the first opening 102. The portion of the plug end 202 extending out of the first opening 102 can form a latch position. When the user needs to use the charging device, he / she can latch the latch position to rotate the plug 2 so that the plug end 202 is removed from the receiving groove 10.

[0050] The first limiting surface 103 is located at one end of the receiving groove 10 facing the first opening 102 along the second direction Y. In the extended state, the pin 2 abuts against the first limiting surface 103. The first limiting surface 103 can constrain the rotation angle of the pin 2 to reduce the probability of poor contact caused by misaligned insertion of the pin 2. The first limiting surface 103 abuts against the pin 2, so that no gap is formed between the pin 2 and the receiving groove 10 on the side facing away from the first opening 102 in the second direction Y. The electrical connection component 3 will not be exposed from the side of the receiving groove 10 facing away from the first opening 102. In this way, the insulating shield 4 can effectively provide insulation by shielding the side facing the first opening 102. The insulating shield 4 is located on the side of the pin 2 facing the first opening 102. The insulating shield 4 can shield the side of the pin 2 facing the first opening 102 to form insulation protection.

[0051] For example, the spacing between the two opposite walls of the receiving groove 10 along the third direction Z is adapted to the size of the pin 2, so that the two side walls of the pin 2 are in smooth contact with the two groove walls. Alternatively, it can have a set gap, which is a relatively small gap that is not large enough for the conductive filament to pass through. That is, the electrical connection component 3 is not easily exposed from the opposite sides of the pin 2 along the third direction Z to avoid electric shock.

[0052] In some embodiments of this application, such as Figures 1 to 5 As shown, the receiving groove 10 is provided with a clearance groove 5 on one side along the third direction Z. The clearance groove 5 is connected to the receiving groove 10. The third direction Z intersects with the first direction X and the second direction Y. In the retracted state, the insulating shield 4 is accommodated in the clearance groove 5. In the extended state, at least a portion of the insulating shield 4 extends into the receiving groove 10.

[0053] The insulating shield 4 can change its position depending on whether it is in the retracted or extended state. In the retracted state, the plug end 202 of the pin 2 is located in the receiving groove 10. At this time, the insulating shield 4 is not required for insulation protection. The insulating shield 4 is accommodated in the clearance groove 5 connected to the receiving groove 10, which reduces the probability of the insulating shield 4 interfering with the pin 2. In the extended state, at least a part of the insulating shield 4 extends into the receiving groove 10 to shield the adapter end 201, which reduces the probability of external conductive objects (such as metal wires) making electrical contact with the adapter end 201 and improves the insulation protection effect of the charging device.

[0054] In some embodiments of this application, such as Figures 1 to 5 As shown, the groove wall of the clearance groove 5 includes two second limiting surfaces 50 opposite each other along the second direction Y, and at least a portion of the insulating shield 4 is limited between the two second limiting surfaces 50.

[0055] Two opposing second limiting surfaces 50 along the second direction Y constrain the movement of the insulating shield 4 along the second direction Y, reducing the possibility of the insulating shield 4 swinging in directions other than the third direction Z. Furthermore, the two second limiting surfaces 50 limit at least a portion of the insulating shield 4, separating at least a portion of the insulating shield 4 from other components, reducing friction between the insulating shield 4 and other components, and protecting other components from damage caused by friction.

[0056] In some embodiments of this application, such as Figures 1 to 3 As shown, the pin assembly includes two pins 2 spaced apart along the third direction Z. The housing 1 forms two receiving grooves 10 spaced apart along the third direction Z. The clearance groove 5 communicates between the two receiving grooves 10. The insulating shield 4 is elastic along the third direction Z. The insulating shield 4 can extend into the two receiving grooves 10 or retract into the clearance groove 5 by telescoping along the third direction Z.

[0057] For example, such as Figure 2 As shown, the clearance groove 5 is connected to two receiving grooves 10. The groove wall of the clearance groove 5 also includes a third limiting surface. The third limiting surface faces the inner cavity 13. Both ends of the third limiting surface along the second direction Y are connected to the second limiting surface 50. The setting of the third limiting surface further restricts the position of the insulating shield 4 to improve the stability of the insulating shield 4 during the extension and retraction process.

[0058] Two pins 2 are spaced apart along the third direction Z, and two receiving slots 10 are also spaced apart along the third direction Z. In the retracted state, the two pins 2 can be received in their respective receiving slots 10. The insulating shield 4 is elastic along the third direction Z, allowing it to extend into the two receiving slots 10 or retract into the clearance slots 5. In the retracted state, the insulating shield 4 retracts into the clearance slots 5; in the extended state, a portion of the insulating shield 4 extends into the two receiving slots 10. The elasticity of the insulating shield 4 enables movement between the receiving slots 10 and the clearance slots 5, eliminating the need for additional complex components and resulting in a simple structure.

[0059] In some embodiments of this application, such as Figures 2 to 4 As shown, the insulating shield 4 includes an elastic part 40 and two shielding parts 41. The elastic part 40 is accommodated in the relief groove 5 and has elasticity along the third direction Z. The two shielding parts 41 are respectively connected to the opposite ends of the elastic part 40 along the third direction Z. In the retracted state, the elastic part 40 is in a compressed state, and the two shielding parts 41 respectively abut against the two pins 2.

[0060] For example, the elastic part 40 and the two shielding parts 41 of the insulating shielding member 4 are integrally molded structures. The integrally molded structure facilitates improved production efficiency and has good economic benefits.

[0061] For example, the elastic portion 40 of the insulating shield 4 is bonded to the two shield portions 41.

[0062] For example, the material of the insulating shield 4 may include, but is not limited to, plastic materials such as polyethylene, polypropylene, polyvinyl chloride and acrylonitrile-butadiene-styrene copolymer. Plastic materials have insulating properties, can form reliable insulating protection, and are inexpensive, thus having good economic applicability.

[0063] For example, in the retracted state, the elastic part 40 is accommodated in the clearance groove 5. At this time, the elastic part 40 is in a compressed state, and the two blocking parts 41 retract into the clearance groove 5 as the elastic part 40 is compressed. In the extended state, the elastic part 40 is in a natural state or a compressed state, and the two blocking parts 41 are respectively located in the two receiving grooves 10.

[0064] The elastic part 40 is accommodated in the clearance groove 5. Two blocking parts 41 are respectively connected to the opposite ends of the elastic part 40 along the third direction Z. The two blocking parts 41 can reciprocate along the third direction Z under the elastic force of the elastic part 40. The elastic part 40 provides elastic potential energy. The two blocking parts 41 connected to the elastic part 40 can block the adapter end 201 of the plug 2 passing through the second slot. In the retracted state, the elastic part 40 is accommodated in the clearance groove 5. At this time, the two blocking parts 41 retract to the clearance groove 5 and abut against the two plugs 2 respectively, so that the elastic part 40 is in a compressed state. When the plug 2 rotates from the state of extending along the second direction Y to the state of extending along the first direction X, the plug 2 moves away from the blocking parts 41 until it is completely disengaged, so that the two blocking parts 41 extend into the receiving groove 10 under the elastic restoring force of the elastic part 40. In the extended state, the elastic part 40 is in either a natural or compressed state. When switching from the retracted state to the extended state, the elastic part 40 releases the elastic potential energy accumulated in the compressed state, pushing the two blocking parts 41 to move along the third direction Z into the two receiving slots 10 respectively. The elasticity of the elastic part 40 enables the two blocking parts 41 to move between the receiving slot 10 and the clearance slot 5, eliminating the need for additional complex components. This results in a simple structure, ease of manufacturing, low cost, and good economic adaptability.

[0065] In some embodiments of this application, such as Figures 2 to 4 As shown, in the extended state, the shielding part 41 is in contact with the bottom wall of the receiving groove 10, and / or, the shielding part 41 is in contact with the groove wall of the receiving groove 10 facing the clearance groove 5, and / or, a portion of the shielding part 41 is located inside the clearance groove 5.

[0066] It is understandable that the opening formed at the end of the receiving groove 10 away from the inner cavity 13 of the housing 1 along the first direction X is the groove opening of the receiving groove 10, and the bottom wall of the groove is the wall surface of the receiving groove 10 facing the groove opening of the receiving groove 10 along the first direction X.

[0067] For example, the shielding part 41 contacts the bottom wall of the receiving groove 10 and the groove wall of the receiving groove 10 facing the clearance groove 5; for example, the shielding part 41 contacts the bottom wall of the receiving groove 10 and a portion of the shielding part 41 is located within the clearance groove 5; for example, the shielding part 41 contacts the groove wall of the receiving groove 10 facing the clearance groove 5 and a portion of the shielding part 41 is located within the clearance groove 5; for example, the shielding part 41 contacts the bottom wall of the receiving groove 10, the shielding part 41 contacts the groove wall of the receiving groove 10 facing the clearance groove 5, and a portion of the shielding part 41 is located within the clearance groove 5.

[0068] In the extended state, the shielding part 41 contacts the bottom wall of the receiving groove 10 and the groove wall facing the clearance groove 5. The part of the shielding part 41 connected to the elastic part 40 is located in the clearance groove 5. Thus, the shielding part 41 can improve the effectiveness of shielding, thereby improving the insulation protection performance.

[0069] In some embodiments of this application, such as Figure 1 As shown, the surface of the shielding part 41 facing the opening of the receiving groove 10 along the first direction X includes a guide slope 410. The end of the guide slope 410 away from the elastic part 40 is inclined toward the side close to the bottom wall of the receiving groove 10. The guide slope 410 can abut against the pin 2.

[0070] It is understood that the surface of the blocking part 41 facing the opening of the receiving groove 10 along the first direction X includes a guide slope 410. That is, in the extended state, when the blocking part 41 is located in the receiving groove 10, the end of the blocking part 41 away from the bottom wall of the receiving groove 10 along the first direction X includes the guide slope 410. The end of the guide slope 410 away from the elastic part 40 is inclined towards the side close to the bottom wall of the receiving groove 10. That is, at both ends of the blocking part 41 along the third direction Z, the dimension of the end of the blocking part 41 connected to the elastic part 40 in the first direction X is larger than the dimension of the end of the blocking part 41 away from the elastic part 40 in the first direction X.

[0071] When the pins 2 rotate from extending in the first direction X to extending in the second direction Y, both pins 2 rotate simultaneously until they contact the highest point of the guide slope 410 at the receiving groove 10. The two pins 2 continue to rotate, and under the rotational force of the pins 2 and the guiding action of the guide slope 410 as it transitions from the highest point to the lowest point, the two blocking parts 41 move towards each other in the third direction Z. During this process, the elastic part 40 undergoes compression deformation due to the displacement of the blocking parts 41. The guide slope 410 allows the blocking parts 41 to move in the third direction Z under the downward pressure of the pins 2, making the movement of the blocking parts 41 smoother and simplifying the structure.

[0072] For example, the elastic part 40 can be, but is not limited to, an elastic component such as a helical spring, an air spring, a torsion bar spring, a rubber spring, or a shape memory alloy.

[0073] In some embodiments of this application, such as Figures 1 to 4 As shown, the elastic part 40 includes an elastic arm extending along a curve, and the two ends of the elastic arm are respectively connected to the portions of the two shielding parts 41 that are closer to the bottom wall of the receiving groove 10 along the first direction X.

[0074] For example, such as Figure 4 As shown, Figure 4The dotted line in the diagram divides the elastic portion 40 into two parts: the area above the dotted line is the upper half, and the area below the dotted line is the lower half. The elastic portion 40 extends along one side of the first direction X, i.e. Figure 4 The upper half of the dotted line has a first bend and a second bend, and the elastic part 40 is on the other side of the first direction X, i.e. Figure 4 The lower half of the dotted line has a third bend, and the first bend and the second bend are connected by the third bend. In the retracted state, the two blocking parts 41 move towards each other along the third direction Z to compress the elastic arm, and the first bend and the second bend move closer to each other.

[0075] For example, the elastic part 40 is a cantilever elastic structure, which is less expensive.

[0076] The two ends of the elastic arm extending along the curve are respectively connected to the parts of the two shielding parts 41 that are closer to the bottom wall of the receiving groove 10 along the first direction X, so that when the elastic part 40 is compressed and extended, the movement of the shielding part 41 along the third direction Z is more balanced and stable.

[0077] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, the pin 2 includes a strip-shaped conductive element and a sleeve-shaped insulating element 204. One end of the conductive element is electrically connected to the electrical connection assembly 3 and part of its outer surface is covered with the insulating element 204. The other end is a plug-in end 202.

[0078] The insulating component 204 is installed in the non-contact area, that is, the area on the pin 2 that does not need to be in electrical contact with the external power source, which can improve the safety of use.

[0079] For example, such as Figure 1 As shown, the charging device includes a circuit board 6, which is located in the inner cavity 13 and electrically connected to the electrical connection assembly 3.

[0080] For example, such as Figure 1 As shown, the electrical connection assembly 3 includes a spring contact 30, which is electrically connected to the adapter end 201. The spring contact 30 also positions the pin 2 in two states: one extending along the second direction Y, and the other extending along the first direction X. The spring contact 30 includes a first positioning portion and a second positioning portion. When the pin 2 is in the state extending along the second direction Y, at least a portion of the adapter end 201 of the pin 2 abuts against the first positioning portion, making the pin 2 securely positioned in the state extending along the second direction Y. When the pin 2 is in the state extending along the first direction X, at least a portion of the adapter end 201 of the pin 2 abuts against the second positioning portion, making the pin 2 securely positioned in the state extending along the first direction X. The specific structure and working principle of the spring contact 30 can be found in existing technology and will not be described further here.

[0081] For example, the spring 30 includes a connection hole, and the spring 30 is connected to the circuit board 6 via a screw or other connector.

[0082] For example, the charging device includes an indicator light assembly (not shown in the figure).

[0083] For example, the charging device includes a Type-C or Type-A interface (not shown in the figure).

[0084] For example, the charging device can be, but is not limited to, a power bank, a power adapter, etc.
