Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a charger. Background Technology

[0002] A charger connects to a socket via its prongs. In related technologies, a retractable charger has prongs and a housing. The housing has a recess, and the prongs are rotatably connected to the housing, allowing them to rotate into or out of the recess. When the prongs are in the recess, they fold into the housing, reducing the charger's size and facilitating storage. When the prongs are out of the recess, they can be properly plugged into the socket. When the charger is plugged into a socket, it is generally suspended, with only the prongs supporting the entire housing. To prevent relative swaying between the housing and the prongs, a spring is typically installed inside the housing. This spring abuts against the prongs, preventing them from swinging relative to each other and ensuring the prongs support the housing. When the prongs need to retract into the grooves, the prongs push the spring contacts and rub against them. After the prongs are folded multiple times, the torque of the spring contacts gradually decreases, and the contact force between the spring contacts and the prongs becomes smaller. This causes the prongs to swing relative to the housing, and the support force of the prongs on the housing when they are in contact with the socket becomes weaker. The prongs are prone to coming out of the socket or becoming loose, which can lead to safety issues. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a charger that prevents the plug and the casing from swinging relative to each other when the plug is connected to the socket, thereby improving safety during use.

[0005] A power receiving part is rotatably connected to the housing, and the power receiving part can be rotated to a use position or a storage position; a first limiting hole is provided on the power receiving part; A limiting part is movably disposed within the housing. When the power receiving part is in the use position, the first limiting hole is located on the movement path of the limiting part, and the limiting part can be inserted and engaged with the first limiting hole. An elastic element, connected to the limiting part, is used to drive the limiting part closer to the electrical contact part.

[0006] The charger according to the embodiments of this application has at least the following beneficial effects: When the contact part is rotated to the use position, the limiting part can be inserted into the first limiting hole of the contact part under the elastic force of the elastic member, thereby limiting the rotation of the contact part and keeping the contact part in the use position. The limiting part, together with the contact part, improves the support of the housing. When the contact part is plugged into the socket, the contact part is less likely to swing relative to the housing, and the connection between the contact part and the socket is stable, improving the safety of the charger. When it is necessary to rotate the contact part to the storage position, the limiting part is given a force that resists the elastic force of the elastic member, causing the limiting part to exit the first limiting hole, thereby releasing the limiting part from the contact part. The contact part can then rotate normally to the storage position, reducing the size of the charger and facilitating storage. Furthermore, the charger of this application has a simple structure and is easy to operate.

[0024] Reference Figure 1 , Figure 5 and Figure 6 The charger according to an embodiment of this application includes: a housing 100, a power receiving part 200, a limiting part 300, and an elastic member 400.

[0025] The power receiving part 200 is rotatably connected to the housing 100, and the power receiving part 200 can be rotated to a use position or a storage position; a first limiting hole 230 is provided on the power receiving part 200; The limiting part 300 is movably disposed within the housing 100. When the power receiving part 200 is in the use position, the first limiting hole 230 is located on the movement path of the limiting part 300, and the limiting part 300 can be inserted and engaged with the first limiting hole 230. The elastic element 400 is connected to the limiting part 300 and is used to drive the limiting part 300 closer to the power receiving part 200.

[0026] Understandably, the housing 100 has a receiving groove 122. Under the action of external force, the power receiving part 200 can swing relative to the housing 100. The pins 220 of the power receiving part 200 can rotate out of the receiving groove 122, so that the power receiving part 200 is in the use position. At this time, the pins 220 of the power receiving part 200 can be normally plugged into the socket. Correspondingly, the pins 220 of the power receiving part 200 can also rotate into the receiving groove 122, so that the pins 220 are in the storage position. At this time, the pins 220 are stored in the receiving groove 122. The pins 220 and the housing 100 are folded relative to each other, which can reduce the size of the charger and make it easy to store and carry.

[0027] It should also be understood that the elastic element 400 applies a force to the limiting part 300 as it approaches the contact part 200, thus keeping the limiting part 300 in contact with the contact part 200. When using the charger of this application, refer to... Figure 4 and Figure 5 When the power receiving part 200 is rotated to the use position, the first limiting hole 230 will rotate to a position opposite to the limiting part 300. The first limiting hole 230 is located on the movement path of the limiting part 300. Under the elastic force of the elastic member 400, the limiting part 300 will be inserted into the first limiting hole 230, and under the elastic force of the elastic member 400, the limiting part 300 is not easy to disengage from the first limiting hole 230. The insertion and engagement of the limiting part 300 and the first limiting hole 230 can limit the rotation of the power receiving part 200, thereby keeping the power receiving part 200 in the use position. That is, by limiting the part 300, the supporting effect of the power receiving part 200 on the housing 100 can be improved, which can prevent the power receiving part 200 from swinging relative to the housing 100 when it is engaged with the socket, ensuring the connection stability between the power receiving part 200 and the socket, and improving the safety of the charger of this application.

[0028] It should also be understood that when it is necessary to store the charger specified in this application, please refer to... Figure 6 A force is applied to the limiting part 300 to move it away from the power receiving part 200, compressing the elastic member 400 and disengaging the limiting part 300 from the first limiting hole 230. Subsequently, the power receiving part 200 is rotated to the storage position, and the positions of the first limiting hole 230 and the limiting part 300 are offset. After the force applied to the limiting part 300 is released, the elastic member 400 rebounds and drives the limiting part 300 to abut against the outside of the power receiving part 200, but does not restrict the rotation of the power receiving part 200. When the power receiving part 200 is rotated to the storage position, the pins 220 of the power receiving part 200 rotate into the receiving groove 122, which can reduce the size of the charger of this application for easy storage.

[0029] In summary, when the power receiving part 200 is rotated to the use position, the limiting part 300, under the elastic force of the elastic member 400, can be inserted into the first limiting hole 230 of the power receiving part 200, thereby restricting the rotation of the power receiving part 200 and keeping it in the use position. The limiting part 300 enhances the support of the power receiving part 200 for the housing 100. When the power receiving part 200 is plugged into the socket, it is less likely to swing relative to the housing 100, ensuring a stable connection between the power receiving part 200 and the socket, thus improving the safety of the charger. When it is necessary to rotate the power receiving part 200 to the storage position, the limiting part 300 is given a force resisting the elastic force of the elastic member 400, causing the limiting part 300 to exit the first limiting hole 230, thereby releasing the limiting part 300 from the power receiving part 200. The power receiving part 200 can then rotate normally to the storage position, reducing the size of the charger and facilitating storage. Furthermore, the charger in this application has a simple structure and is easy to operate.

[0030] To better store the charger in this application and prevent the charging part 200 from easily leaving the storage location, refer to... Figure 6 A second limiting hole 240 is provided on the power receiving part 200. When the power receiving part 200 is in the storage position, the second limiting hole 240 is located on the movement path of the limiting part 300, and the limiting part 300 can be inserted and cooperated with the second limiting hole 240.

[0031] Understandably, when the charger of this application needs to be stored, the connecting part 200 is rotated to the storage position, and the second limiting hole 240 rotates to be opposite to the limiting part 300. The second limiting hole 240 is located on the movement path of the limiting part 300, and the limiting part 300 is inserted into the second limiting hole 240 under the elastic force of the elastic member 400. Under the elastic force of the elastic member 400, the limiting part 300 is not easily disengaged from the second limiting hole 240. The insertion and engagement of the limiting part 300 and the second limiting hole 240 can restrict the rotation of the connecting part 200, thereby keeping the connecting part 200 in the storage position. When the charger of this application needs to be used, refer to... Figure 5 A force is applied to the limiting part 300 to move it away from the power receiving part 200, compressing the elastic member 400 and disengaging the limiting part 300 from the second limiting hole 240. Subsequently, the power receiving part 200 is rotated to the use position, and the positions of the second limiting hole 240 and the limiting part 300 are offset. After the force applied to the limiting part 300 is released, the elastic member 400 rebounds and drives the limiting part 300 to abut against the outside of the power receiving part 200, but does not restrict the rotation of the power receiving part 200. When the power receiving part 200 is rotated to the use position, the limiting part 300 is inserted into the first limiting hole 230 under the elastic force of the elastic member 400, and the pin 220 of the power receiving part 200 can be plugged into the socket.

[0032] Regarding the connection method between the elastic element 400 and the limiting part 300: In this embodiment, refer to Figure 3 and Figure 4 The limiting part 300 is provided with a first abutting structure 310, and the housing 100 is provided with a second abutting structure 110 on the side of the first abutting structure 310 away from the power contact part 200. The two ends of the elastic member 400 are respectively connected to the first abutting structure 310 and the second abutting structure 110.

[0033] Understandably, the second abutting structure 110 is fixedly installed, and the elastic member 400 provides the first abutting structure 310 with a spring force away from the second abutting structure 110, so as to push the limiting part 300 to move toward the power receiving part 200. When the power receiving part 200 is not rotated to the storage position or the use position, the limiting part 300 abuts against the outside of the power receiving part 200 under the action of the elastic member 400. When the power receiving part 200 is rotated to the storage position or the use position, the limiting part 300 will be able to be inserted into the first limiting hole 230 or the second limiting hole 240.

[0034] Specifically, refer to Figure 3 and Figure 4 The elastic element 400 is a compression spring, and the limiting part 300 is a pin. The limiting part 300 is integrally formed with the first abutment structure 310. The elastic element 400 can push the limiting part 300 closer to the contact part 200. (Refer to...) Figure 3 The housing 100 and the second abutment structure 110 are integrally formed. The second abutment structure 110 is disposed inside the housing 100. The first abutment structure 310 forms a limiting groove 111. The bottom of the limiting groove 111 is connected to the elastic member 400, and the elastic member 400 is located in the limiting groove 111. The second abutment structure 110 is also located in the limiting groove 111, so as to limit the installation of the elastic member 400 and the movement of the second abutment structure 110. A through hole 112 is also provided at the bottom of the limiting groove 111. The end of the limiting part 300 away from the power contact part 200 passes through the through hole 112, so as to provide a force to the limiting part 300 away from the power contact part 200.

[0035] In some other embodiments, the elastic element 400 may also be a tension spring, which is connected to the side of the limiting part 300 near the power receiving part 200 to pull the limiting part 300 toward the power receiving part 200.

[0036] In other embodiments, the elastic element 400 may also be a torsion spring, which drives the limiting part 300 to swing toward the power receiving part 200.

[0037] To ensure the installation stability of elastic element 400, refer to Figure 3 In this embodiment, the elastic element 400 is sleeved on the limiting part 300.

[0038] It is understandable that the elastic element 400 is sleeved on the outside of the limiting part 300, which can limit the position of the elastic element 400.

[0039] To facilitate applying force to the limiting part 300 away from the power receiving part 200, refer to Figure 1 , Figure 3 and Figure 4 The charger of this application also includes a switch 500, which is at least partially exposed on the outside of the housing 100. The switch 500 is movably disposed on the housing 100 and is connected to the limiting part 300. The switch 500 can drive the limiting part 300 away from the first limiting hole 230.

[0040] Understandably, when the limiting part 300 needs to disengage from the first limiting hole 230, the portion of the switch 500 exposed on the outside of the housing 100 is activated by finger movement. The switch 500 is fixedly connected to the limiting part 300, and the switch 500 can move the limiting part 300 away from the contact part 200 and disengage from the first limiting hole 230. Similarly, when the limiting part 300 needs to disengage from the second limiting hole 240, the portion of the switch 500 exposed on the outside of the housing 100 is activated by finger movement. The switch 500 will move the limiting part 300 away from the contact part 200 and disengage from the second limiting hole 240. This facilitates moving the limiting part 300 away from either the first limiting hole 230 or the second limiting hole 240, thereby releasing the restriction on the contact part 200. It should also be understood that when the finger releases the force applied to the switch 500, the limiting part 300 moves back to the contact part 200 under the elastic force of the elastic member 400, and at the same time, it will drive the switch 500 to reset.

[0041] Regarding the specific toggle operation of switch 500: In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The switch 500 is in sliding fit with the housing 100.

[0042] It is understandable that when the limiting part 300 needs to disengage from the first limiting hole 230 or the second limiting hole 240, the toggle switch 500 slides in a straight line to push the limiting part 300 to move in a straight line. The toggle switch 500 is simple to operate, and the movement space required for the switch 500 and the limiting part 300 is small, which can reduce the design size of the housing 100.

[0043] In some other embodiments, the switch 500 is a knob, the switch 500 is rotatably engaged with the housing 100, the limiting part 300 is oscillatingly connected to the housing 100, the rotation of the switch 500 causes the limiting part 300 to oscillate, and the first limiting hole 230 and the second limiting hole 240 of the power receiving part 200 can rotate to the oscillation path of the limiting part 300.

[0044] For the specific structure of the housing 100, please refer to... Figure 2 The housing 100 includes a cover plate 120 and a faceplate 130 connected to each other. The power receiving part 200, the limiting part 300 and the switch 500 are all mounted on the cover plate 120.

[0045] It is understandable that by mounting the power receiving part 200, the limiting part 300, and the switch 500 on the cover plate 120, only drilling and other processes are required on the cover plate 120 during the production process. During the assembly process, the power receiving part 200, the limiting part 300, and the switch 500 can be pre-assembled onto the cover plate 120 before the cover plate 120 is assembled with the face shell 130, thus simplifying the production and assembly processes.

[0046] Specifically, the cover plate 120 has a receiving groove 122, and the second abutment structure 110 is disposed on the cover plate 120.

[0047] To improve the stability of the 500 switch during operation, refer to Figure 1 The cover plate 120 has a slide groove 121, and the switch 500 is slidably disposed in the slide groove 121.

[0048] It is understandable that when the switch 500 is toggled, the switch 500 moves along the extension direction of the slide groove 121. The slide groove 121 guides the sliding of the switch 500 so that the direction of the switch 500 is accurate.

[0049] For the specific structure of the power connection section 200, please refer to... Figure 1 , Figure 3 and Figure 4 The power receiving part 200 includes a rotating shaft 210 and at least two pins 220. The pins 220 are fixed to the rotating shaft 210. The rotating shaft 210 is rotatably installed in the housing 100. The limiting part 300 is located on the side of the rotating shaft 210. The first limiting hole 230 is opened on the side of the rotating shaft 210.

[0050] Understandably, the pin 220 is at least partially exposed on the outside of the housing 100, and the exposed portion of the pin 220 can be moved to drive the rotating shaft 210 to rotate. The limiting part 300 is located on the side of the rotating shaft 210, and the limiting part 300 can abut against the side of the rotating shaft 210 under the elastic force of the elastic member 400. The first limiting hole 230 and the second limiting hole 240 are both opened on the side of the rotating shaft 210. The limiting part 300 can be opposite to the first limiting hole 230 or the second limiting hole 240 and inserted into the first limiting hole 230 or the second limiting hole 240.

[0051] It should be understood that when the pin 220 is rotated out of the receiving groove 122 and perpendicular to the end face of the cover plate 120, the pin 220 is in the use position and can be plugged into the socket. When the pin 220 is rotated into the receiving groove 122, the pin 220 is in the retracted position. To facilitate the removal of the pin 220 from the retracted position, the receiving groove 122 extends through the side of the cover plate 120, so that the end of the pin 220 in the retracted position protrudes from the receiving groove 122, facilitating subsequent movement of the pin 220.

[0052] Specifically, refer to Figure 3 The rotating shaft 210 is arranged along the width direction of the cover plate 120, that is, the axial direction of the rotating shaft 210 is parallel to the width direction of the cover plate 120, and the limiting part 300 is arranged along the length direction of the cover plate 120, that is, the axial direction of the limiting part 300 is parallel to the length direction of the cover plate 120.

[0053] To further improve the connection stability between the power connection part 200 and the housing 100 when the power connection part 200 is in the use position or the storage position, refer to Figure 3 and Figure 4 The charger of this application also includes a spring 600, which is disposed on the housing 100 and abuts against the power receiving part 200.

[0054] It is understandable that when the power receiving part 200 is rotated to the use position or the storage position, the spring 600 is in interference fit with the power receiving part 200, and the spring 600 can apply pressure to the power receiving part 200 to keep it in the current position. Thus, the spring 600 assists the limiting part 300 in limiting the power receiving part 200.

[0055] Specifically, the spring 600 is made of metal and can be used to connect to an electrical wire, which in turn connects to an appliance. One end of the plug 220, located inside the housing 100, passes through a pivot 210 and abuts against the spring 600. Thus, when the plug 220 is plugged into the socket, the municipal circuit can be connected to the appliance through the socket, plug 220, spring 600, and electrical wire to charge the appliance. Alternatively, the spring 600 can also abut against the pivot 210 to increase the contact area between the spring 600 and the contact part 200, thereby increasing the pressure on the contact part 200.

[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
