[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] This utility model embodiment provides a power adapter 1000, such as Figures 1-6As shown, the power adapter 1000 includes a housing 100, a plug 200, a charging cable socket 300, a battery connection assembly 400, and a control circuit module 500. The housing 100 includes a main body 110 and a cover 120. The main body 110 has a battery receiving slot 111, and the cover 120 is movably mounted at the opening of the battery receiving slot 111 to conceal or expose it. The plug 200 is mounted on the main body 110 and exposed outside the main body 110, allowing the plug 200 to connect with an external socket to obtain power. The charging cable socket 300 is mounted on the main body 110 and exposed outside the main body 110, allowing the charging cable socket 300 to connect with an external charging cable to deliver power to electronic products. The battery connection assembly 400 includes a positive terminal connector 410 and a negative terminal connector 420. Both the positive terminal connector 410 and the negative terminal connector 420 are mounted in the housing 100 and exposed in the battery receiving slot 111, so that the battery installed in the battery receiving slot 111 can abut against the positive terminal connector 410 and the negative terminal connector 420. The control circuit module 500 is installed in the main body 110 and is electrically connected to the plug 200, the charging cable socket 300, the positive terminal connector 410, and the negative terminal connector 420. This configuration allows the plug 200 to be used with a socket to obtain power to charge electronic products, or the battery to charge electronic products.

[0040] Firstly, the power adapter 1000 provided in this embodiment can be equipped with a battery, so the power adapter 1000 provided in this embodiment can charge electronic products in environments without sockets, expanding the application scenarios of the power adapter 1000 and providing an excellent user experience.

[0041] Secondly, in the power adapter 1000 provided in this embodiment, the cover plate 120 can move relative to the main body 110, thereby covering or exposing the battery receiving slot 111. Therefore, the battery in the battery receiving slot 111 can be exposed by operating the cover plate 120, and then the battery can be replaced. It can be seen that the power adapter 1000 of this embodiment can meet the needs of users with large power consumption by replacing the depleted battery.

[0042] Thirdly, when the power adapter 1000 is in use, the cover 120 will block the opening of the battery receiving slot 111. As a result, the battery will be placed in a relatively enclosed space. When the power adapter 1000 is dropped, the battery is less likely to fly out of the power adapter 1000, reducing the probability of battery loss and providing an excellent user experience.

[0043] It should be noted that the positive electrode connector 410 and the negative electrode connector 420 are exposed in the battery receiving groove 111 only to indicate that the battery in the battery receiving groove 111 can contact the positive electrode connector 410 and the negative electrode connector 420, and not to indicate that the positive electrode connector 410 and the negative electrode connector 420 are both installed in the battery receiving groove 111. For example, if the positive electrode connector 410 or the negative electrode connector 420 is disposed on the cover plate 120, when the cover plate 120 is positioned at the opening of the battery receiving groove 111, the positive electrode connector 410 or the negative electrode connector 420 can also contact the battery, and the positive electrode connector 410 or the negative electrode connector 420 is also considered to be exposed in the battery receiving groove 111.

[0044] It is worth mentioning that there are many specific embodiments in which the cover plate 120 is movably installed at the opening of the battery receiving slot 111. Several embodiments are listed below for illustration:

[0045] In Embodiment 1, the cover plate 120 is detachably connected to the main body 110. After the cover plate 120 is removed, the battery receiving slot 111 is exposed, and the battery can be replaced. After the battery is replaced, the cover plate 120 is simply installed to cover the battery receiving slot 111 to prevent the battery from coming out of the battery receiving slot 111.

[0046] In the second embodiment, the cover plate 120 is slidably connected to the main body 110. The battery receiving slot 111 can be exposed by simply sliding the cover plate 120 open, so as to replace the battery. After the battery is replaced, the battery receiving slot 111 can be covered by simply sliding the cover plate 120 in the opposite direction to prevent the battery from falling out of the battery receiving slot 111.

[0047] refer to Figure 2 , Figure 3 In embodiment three, the cover plate 120 is rotatably connected to the main body 110. The battery receiving slot 111 can be exposed by simply opening the cover plate 120, and then the battery can be replaced. After the battery is replaced, the cover plate 120 can be rotated in the opposite direction to cover the battery receiving slot 111 to prevent the battery from coming out of the battery receiving slot 111.

[0048] refer to Figure 3 , Figure 7 , Figure 8In a specific embodiment, the outer side of the main body 110 is provided with a cover plate 120 receiving groove 112. The opening of the battery receiving groove 111 is connected to the bottom of the cover plate receiving groove 112. The cover plate 120 is rotatably connected to the cover plate 120 receiving groove 112. The cover plate 120 receiving groove 112 includes a groove wall away from the rotation center line of the cover plate 120. A slot 113 is provided in the groove wall. A push button 130 is installed on the cover plate 120. The push button 130 is provided with an insert block 131 that is opposite to the slot 113. The push button 130 is slidably connected to the cover plate 120 in the orientation of the opening of the slot 113, so that the slot 113 can slide into or out of the slot 113.

[0049] Specifically, since the insert 131 aligns with the slot 113 after the cover 120 is closed, and the push button 130 is slidably connected to the cover 120 in the orientation of the slot 113, the insert 131 can be inserted into the slot 113 by sliding it after the cover 120 is closed. This locking mechanism prevents the cover 120 from opening due to external force, thus preventing the battery from dislodging from the battery housing slot 111. When the user needs to replace the battery, they only need to slide the insert 131 in the opposite direction to dislodge it from the slot 113, allowing the cover 120 to be opened and the battery replaced.

[0050] In a specific embodiment, the power adapter 1000 also includes a compression spring (not shown in the figure), which is connected to the push button 130. The compression spring is used to deform and store energy when the plug 131 is removed from the slot 113. In this way, after the cover plate 120 is closed, as long as the push button 130 is released, the compression spring can release energy to drive the plug 131 on the push button 130 to be inserted into the slot 113. There is no need for the user to push the push button 130, making the operation more convenient and thus providing an excellent user experience.

[0051] In a specific embodiment, the power adapter 1000 also includes a torsion spring (not shown in the figure), which is connected to the cover plate 120 and the main body 110. The torsion spring is used to store energy by deformation when the cover plate 120 is closed. In this way, after the user operates the plug 131 to be removed from the slot 113, the torsion spring can release energy to drive the cover plate 120 to open by itself, without the user having to pry open the cover plate 120 by hand, making the operation more convenient and thus providing an excellent user experience.

[0052] refer to Figure 3 , Figure 4 In some embodiments, one of the positive electrode connector 410 and the negative electrode connector 420 is mounted on the cover plate 120, and the other is mounted on the side of the battery receiving groove 111 away from the cover plate 120. The positive electrode connector 410 and / or the negative electrode connector 420 are resilient.

[0053] By implementing this embodiment, after the cover plate 120 is closed, the battery can be subjected to the elastic force provided by the positive terminal connector 410 and / or the negative terminal connector 420, so that the battery will not shake in the battery receiving slot 111. This not only makes the product more textured, but also ensures that the battery can stably contact the positive terminal connector 410 and the negative terminal connector 420, and there will be no poor contact.

[0054] refer to Figure 2 , Figure 3 , Figure 6 In some embodiments, the power adapter 1000 further includes a rotating shaft 600, and the outer side of the main body 110 is provided with a groove 114. The plug 200 is connected to the rotating shaft 600, and the plug 200 is rotatably disposed in the groove 114 through the rotating shaft 600 so that the plug 200 can be screwed out or screwed into the groove 114.

[0055] By implementing this embodiment, the plug 200 can be screwed out of the recess 114 when needed and screwed back into the recess 114 when not in use. Firstly, the design allowing the plug 200 to screw into the recess 114 reduces the space occupied by the power adapter 1000 during carrying or storage, making the power adapter 1000 easier to carry and store. Secondly, the design preventing the plug 200 from being exposed when not in use and thus avoiding accidental damage, such as breakage or deformation.

[0056] This makes it easy to store the power adapter 1000 and also protects the plug 200 when it is not in use, preventing it from being damaged by external forces.

[0057] refer to Figures 9-11 In some embodiments, the rotating shaft 600 passes through the main body 110, and a positioning protrusion 610 is provided on the outer peripheral surface of the rotating shaft 600. The positioning protrusion 610 is located inside the main body 110. The power adapter 1000 also includes a positioning seat 700. In a direction perpendicular to the axis of the rotating shaft 600, the positioning seat 700 is disposed beside the rotating shaft 600. The side of the positioning seat 700 facing the rotating shaft 600 is provided with an elastic protrusion 710 that cooperates with the positioning protrusion 610. Both sides of the elastic protrusion 710 are used to abut against the positioning protrusion 610 to position the plug 200 after it is screwed out of and into the groove 114.

[0058] Specifically, when the plug 200 is located within the groove 114, the positioning protrusion 610 abuts against one side of the elastic protrusion 710. This position the plug 200 to a certain extent, preventing it from being unscrewed from the groove 114 by minor external forces. Only when a force sufficient to move or deform the elastic protrusion 710 is applied to the plug 200 can it be unscrewed from the groove 114. Similarly, when the plug 200 is outside the groove 114, the positioning protrusion 610 abuts against the other side of the elastic protrusion 710. This position the plug 200 to a certain extent, preventing it from being unscrewed from the groove 114 by minor external forces. Only when a force sufficient to move or deform the elastic protrusion 710 is applied to the plug 200 can it be unscrewed from the groove 114. Therefore, by implementing this embodiment, unnecessary rotation of the plug 200 due to external forces can be effectively avoided.

[0059] refer to Figures 9-11 In a specific embodiment, the positioning seat 700 is provided with a through-hole 720 on the side facing the rotating shaft 600. An elastic arm 730 extends from the inner wall of the through-hole 720, and an elastic protrusion 710 is disposed on the elastic arm 730 so that the elastic protrusion 710 is suspended at the through-hole 720.

[0060] By implementing this embodiment, the rotation of the plug 200 can synchronously drive the positioning protrusion 610 to apply pressure to the elastic protrusion 710. Since the elastic protrusion 710 is provided on the elastic arm 730, the force applied to the elastic protrusion 710 will cause the elastic arm 730 to bend and store energy. The bending of the elastic arm 730 causes the elastic protrusion 710 to move away from the positioning protrusion 610, thereby enabling the plug 200 to be smoothly screwed into or out of the groove 114.

[0061] In another specific embodiment, the elastic bump 710 is made of elastic materials such as silicone or rubber.

[0062] By implementing this embodiment, the rotation of the plug 200 can synchronously drive the positioning protrusion 610 to apply pressure to the elastic protrusion 710. Since the elastic protrusion 710 is made of elastic material, the force applied to the elastic protrusion 710 will cause the elastic protrusion 710 to deform and store energy, thereby enabling the plug 200 to smoothly screw into or out of the groove 114.

[0063] refer to Figure 6 In some embodiments, the power adapter 1000 further includes a conductive bushing 800, which is fixed to the main body 110 and electrically connected to the control circuit module 500. The conductive bushing 800 is sleeved on the rotating shaft 600 and abuts against the rotating shaft 600 so that the plug 200 can be electrically connected to the control circuit module 500 through the rotating shaft 600 and the conductive bushing 800.

[0064] Specifically, the existing technology uses a wire to connect the plug 200 and the control circuit module 500. When the plug 200 rotates, the wire will be deformed by force. As the number of times the plug 200 rotates increases, the conductive wire is easy to break. Therefore, the power adapter 1000 of the existing technology has a relatively short service life and a poor user experience.

[0065] In this embodiment, the plug 200 is electrically connected to the control circuit module 500 via a rotating shaft 600 and a conductive sleeve 800. More specifically, the conductive sleeve 800 is fixed to the main body 110, and the rotating shaft 600 is inserted into and abuts against the conductive sleeve 800, thereby achieving the electrical connection between the plug 200 and the control circuit module 500 via the rotating shaft 600 and the conductive sleeve 800. By implementing this embodiment, the conductive sleeve 800 remains stationary when the plug 200 rotates, thus preventing wire breakage, extending the service life of the power adapter 1000, and providing a better user experience.

[0066] refer to Figure 6 In a specific embodiment, the plug 200 has two pins 210 spaced apart axially on the rotating shaft 600. Two conductive bushings 800 are provided, spaced apart axially on the rotating shaft 600. The rotating shaft 600 includes two conductive inserts 630 and an insulating shaft 640. The two conductive inserts 630 are respectively inserted into and abut against the two conductive bushings 800, and are electrically connected to the two pins 210 respectively. The insulating shaft 640 is connected between the two conductive inserts 630.

[0067] By implementing this embodiment, both synchronous rotation of the two pins 210 can be ensured, preventing them from having different angles, and short circuits can also be avoided. Specifically, since the two pins 210 are respectively connected to two conductive shafts, and the two conductive shafts are connected through an insulating shaft 640, the two conductive shafts can achieve synchronous rotation through the insulating shaft 640, preventing the two pins 210 from having different angles. Furthermore, since the insulating shaft 640 is insulated, the two conductive shafts are not electrically connected, thus preventing short circuits.

[0068] refer to Figure 9 , Figure 11 In some embodiments, the positioning seat 700 has two mounting ears 740 on the side facing the rotating shaft 600. Each mounting ear 740 has an arc-shaped mounting groove 741, which can limit and accommodate the rotating shaft 600, thereby increasing the rotational stability of the rotating shaft 600. Two positioning rings 620 are provided on the outer circumferential surface of the rotating shaft 600. The two positioning rings 620 are located between the two mounting ears 740 and abut against the two mounting ears 740 respectively.

[0069] By implementing this embodiment, after the rotating shaft 600 is installed in the arc-shaped mounting groove 741, the two positioning rings 620 will be located between the two mounting ears 740 and abut against the two mounting ears 740 respectively. Constrained by the two mounting ears 740 and the two positioning rings 620, the rotating shaft 600 cannot move in its axial direction, thereby avoiding the situation where the rotating shaft 600 gradually deviates from its original installation position as the usage time increases.

[0070] refer to Figure 1 In some embodiments, there are several charging cable ports 300, and the several charging cable ports 300 are of different types.

[0071] By implementing this embodiment, the power adapter 1000 can be adapted to charging cables with different charging heads, increasing the versatility of the power adapter 1000. Specifically, the plurality of charging cable ports 300 can be two charging cable ports 300, three charging cable ports 300, or even more than three charging cable ports 300. This embodiment does not limit this. The charging cable ports 300 can be Type-A female ports, Type-C female ports, Lightning, Micro-USB female ports, etc., and this embodiment does not limit this.

[0072] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
