[0021] This utility model provides a charging device, as shown in the following embodiment. Figures 1-4The device includes a housing 1, a charging circuit board 2, a charging plug 3, and a flexible switch structure 4. A plug hole 101 is provided on one side wall of the housing 1, and a sliding groove 102 is provided on each of the two side walls adjacent to this side wall. The sliding grooves 102 are arranged along a first direction. The charging circuit board 2 is provided with a charging plug 3 arranged along the first direction, corresponding to the plug hole 101. A flexible switch structure 4 is provided on each side of the charging circuit board 2 along a second direction. The two flexible switch structures 4 slide within the two sliding grooves 102 respectively, allowing the charging plug 3 to extend outside the housing 1 or be hidden inside the housing 1. The first direction and the second direction are two mutually perpendicular directions; for example, the first direction is the length direction of the charging device, and the second direction is the width direction of the charging device.

[0022] As an example, a charging device (such as a power bank) includes a housing 1, a charging circuit board 2, a charging plug 3, and a flexible switch structure 4. A plug hole 101 is provided on one side wall of the housing 1, and a sliding groove 102 is provided on each of the two side walls of the housing 1 adjacent to the side wall. The sliding grooves 102 are arranged along a first direction. For example, the housing 1 is a rectangular structure, including a bottom wall and four side walls, namely a front side wall, a rear side wall, a left side wall, and a right side wall. The plug hole 101 is provided on the left side wall, and the two sliding grooves 102 are respectively provided on the front side wall and the rear side wall. The charging circuit board 2 is provided with a charging plug 3 (Type C charging plug) arranged along the first direction. The charging plug 3 is arranged corresponding to the plug hole 101. The charging circuit board 2 is provided with a spring switch structure 4 on each side along the second direction. The two spring switch structures 4 slide in the two sliding grooves 102 respectively. With this arrangement, the two spring switch structures 4 can be securely installed in the two sliding grooves 102 of the housing 1 by utilizing the elastic force of the two spring switch structures 4. By pushing the two spring switch structures 4 to slide in the two sliding grooves 102 respectively, the user can drive the charging circuit board 2 and the charging plug 3 to move along the first direction. Specifically, the charging plug 3 can move in the plug hole 101 to extend the charging plug 3 outside the housing 1 or hide it inside the housing 1.

[0023] In this example, the charging circuit board 2 and the charging plug 3 are movably mounted inside the housing 1 via two elastic switch structures 4 and two sliding grooves 102, enabling the charging plug 3 to have a retractable function. When charging is needed, pushing the two elastic switch structures 4 forward simultaneously allows the charging plug 3 to extend from the housing 1. When not in use, pushing the two elastic switch structures 4 backward simultaneously retracts the charging plug 3 back into the housing 1. With this configuration, the charging plug 3 does not require a wire connection, making it convenient for users to operate. Simply pushing the two elastic switch structures 4 extends the charging plug 3 for use, eliminating the need for the cumbersome process of unplugging a wire. When not in use, it can be hidden inside the housing 1, eliminating concerns about the charging plug 3 puncturing external objects or the user's body, and also eliminating the need for a protective cover on the charging plug 3, saving costs. This makes the charging device more convenient to use, safer, and more aesthetically pleasing.

[0024] The charging device in this example combines the advantages of the built-in charging plug 3 (which can be concealed) with the advantage of the built-in fixed Type-C charging plug (which does not require a charging cable). It perfectly integrates the advantages of both. Compared with existing charging devices, the charging plug 3 has a retractable function, is convenient to use, takes up little space, and does not require space on the charging device; it reduces safety hazards, preventing the charging plug 3 from hitting other objects or being easily scratched by other objects, and is more portable, so it will not poke the body when put in a pocket; it also improves the aesthetics and safety of the charging device.

[0025] In one embodiment, reference is made to Figure 1 The housing 1 has a sliding groove 102 and a locking groove 103 on its side wall. The sliding groove 102 and the locking groove 103 on the same side wall are arranged at intervals along a third direction / a first direction. The third direction, the first direction and the second direction are perpendicular to each other. For example, the third direction is the height direction of the charging device. Each locking groove 103 has at least two locking holes 104 at intervals along the first direction. Each elastic switch structure 4 has a locking pin 5. The two locking pins 5 are located in the corresponding locking holes 104 to lock the two elastic switch structures 4.

[0026] As an example, a locking groove 103 is provided on the side wall of the housing 1 where the sliding groove 102 is provided. The sliding groove 102 and the locking groove 103 on the same side wall are arranged at intervals along a third direction / a first direction. At least two locking holes 104 are provided in each locking groove 103 at intervals along the first direction. Each elastic switch structure 4 is provided with a locking pin 5. In use, when the two locking pins 5 are respectively located in the corresponding locking holes 104, the two elastic switch structures 4 can be locked. At this time, the charging plug 3 and the charging circuit board 2 are locked so that the user can charge or use them or hide them in the housing 1. For example, there are two locking holes 104, which are respectively located at the two ends of the locking groove 103. Specifically, one locking hole 104 is located at the front end of the locking groove 103, and the other is located at the rear end of the locking groove 103. When the locking pins 5 of the two elastic switch structures 4 are respectively inside the locking holes 104 at the front end of the two locking grooves 103, the charging plug 3 extends out of the housing 1 and is locked, which is convenient for the user. When the locking pins 5 of the two elastic switch structures 4 are respectively inside the locking holes 104 at the rear end of the two locking grooves 103, the charging plug 3 is hidden inside the housing 1 and locked, which can hide and protect the charging plug 3.

[0027] Specific operation process: When charging is needed, press both elastic switch structures 4 simultaneously to overcome their elastic force, causing the locking pin 5 to move from the locking hole 104 at the rear end of the locking groove 103 to another part of the locking groove 103. At this time, the two elastic switch structures 4 are unlocked. Push the two elastic switch structures 4 forward until the locking pin 5 enters the locking hole 104 at the front end of the locking groove 103. At this time, the two elastic switch structures 4 are locked, and the charging plug 3 extends fully from the housing 1 and will not move backward when plugged into an item to be charged (such as a mobile phone). When not in use, press both elastic switch structures 4 simultaneously to overcome their elastic force, causing the locking pin 5 to move from the locking hole 104 at the front end of the locking groove 103 to another part of the locking groove 103. In other parts of 03, the two elastic switch structures 4 are unlocked. Pushing the two elastic switch structures 4 backward until the locking pin 5 enters the locking hole 104 at the rear end of the locking groove 103, the two elastic switch structures 4 are locked, and the charging plug 3 retracts into the housing 1. This design eliminates the need for a power cord connection for the charging plug 3, making it convenient for users. Simply pushing the two elastic switch structures 4 extends the charging plug 3 for use, eliminating the need for a separate power cord. When not in use, it can be hidden inside the housing 1, preventing any danger from the charging plug 3 poking objects or the user, and eliminating the need for a protective cover, thus saving costs. This makes the charging device more convenient, safer, and more aesthetically pleasing. The number of locking holes 104 can be multiple, allowing the charging plug 3 to be locked at different extension lengths as needed.

[0028] In one embodiment, reference is made to Figure 1 and Figure 4 Each elastic switch structure 4 includes an elastic component 41 and a switch 42; the first end of each elastic component 41 is connected to the charging circuit board 2, the second end of each elastic component 41 is connected to the corresponding switch 42, and each switch 42 is movably installed in the corresponding sliding groove 102 along the first direction.

[0029] As an example, each elastic switch structure 4 includes an elastic component 41 and a switch 42. During installation, the first end of each elastic component 41 is connected to the charging circuit board 2, and the second end of each elastic component 41 is connected to the corresponding switch 42. This configuration allows the elastic force of the elastic component 41 to abut against the side wall of the housing 1, enabling the corresponding switch 42 to be movably installed in the corresponding sliding groove 102 along a first direction. The locking pin 5 can be an independent structure, located on the switch 42; alternatively, the locking pin 5 can be an integral part of the switch 42. The elastic force of the elastic component 41 can keep the switch 42 moving towards the housing 1, allowing the locking pin 5 to enter the locking hole 104 from other parts of the locking groove 103, thereby locking the switch 42 and locking the charging plug 3 in either the state of extending outside the housing 1 or being hidden inside the housing 1. When it is necessary to hide the charging plug 3 inside the housing 1 or extend it outside the housing 1, the user can press both switches 42 at the same time to overcome the elastic force of the elastic component 41, allowing the locking pin 5 to move out of the locking hole 104. At this time, the switch 42 is unlocked and can move within the sliding groove 102 to adjust the position of the charging plug 3.

[0030] In one embodiment, reference is made to Figure 1 The elastic component 41 includes a pin holder 411, a pin 412, and an elastic element 413. The pin holder 411 is fixed on the charging circuit board 2. The first end of the pin 412 is inserted into the pin holder 411, and the second end of the pin 412 is connected to the switch 42. The elastic element 413 is fitted onto the pin 412. The first end of the elastic element 413 abuts against or is inserted into the pin holder 411, and the second end of the elastic element 413 abuts against the switch 42.

[0031] As an example, the elastic component 41 includes a pin holder 411, a pin 412, and an elastic element 413 (e.g., a spring). During installation, the pin holder 411 is fixed to the charging circuit board 2, the first end of the pin 412 is inserted into the pin holder 411, and the second end of the pin 412 is connected to the switch 42, allowing the pin 412 to move within the pin holder 411. The elastic element 413 is fitted onto the pin 412, with the first end of the elastic element 413 abutting against or inserted into the pin holder 411, and the second end of the elastic element 413 abutting against the switch 42. This configuration utilizes the elastic force of the elastic element 413 to maintain a tendency for the switch 42 to move towards the housing 1, allowing the switch 42 to drive the pin 412. The switch 42 moves out of the socket 411 and abuts against the side wall of the housing 1, allowing the locking pin 5 to enter the locking hole 104 from other parts of the locking groove 103 to lock the switch 42, locking the charging plug 3 in either the state of extending out of the housing 1 or being hidden inside the housing 1. When it is necessary to hide the charging plug 3 inside the housing 1 or extend it outside the housing 1, the user can press both switches 42 at the same time to overcome the elastic force of the elastic element 413, allowing the locking pin 5 to move out of the locking hole 104. At the same time, the switch 42 can drive the pin 412 into the socket 411, at which point the switch 42 is unlocked and can move within the sliding groove 102 to adjust the position of the charging plug 3.

[0032] In this example, when the power switch 42 is pressed, the locking pin 5, which is integrated with the power switch 42, disengages from the locking hole 104. Then, the power switch 42 is slid forward. At this time, since the pin 412 connected to the power switch 42 and the pin seat 411 fixed on the charging circuit board 2 are engaged, the charging circuit board 2 can be moved forward, and the charging plug 3 also moves forward. Until the locking pin 5 reaches another locking hole 104, the power switch 42 is pushed outward by the elastic force of the elastic element 413. At this time, the locking pin 5 is locked in the locking hole 104 and cannot move. The charging plug 3 extends out of the housing 1 to a suitable length and is fixed. It will not move backward when plugged into the phone. When finished, simply slide back in the opposite direction of the above operation, and the locking pin 5 will fall into the corresponding locking hole 104 and be locked. The charging plug 3 can then be retracted into the housing 1 and fixed. The operation is simple and convenient.

[0033] In one embodiment, reference is made to Figure 1 The switch 42 includes a support plate 421 and a push button 422 disposed on the support plate 421; the support plate 421 abuts against the side wall of the housing 1 under the action of the elastic component 41, the push button 422 is movably installed in the sliding groove 102, and part of the structure of the push button 422 can extend outside the housing 1.

[0034] As an example, the power switch 42 includes a support plate 421 and a push button 422 disposed on the support plate 421. During installation, the support plate 421 abuts against the side wall of the housing 1 under the action of the elastic component 41, so that the push button 422 can be stably installed in the sliding groove 102. The push button 422 is movably installed in the sliding groove 102, and part of the structure of the push button 422 can extend outside the housing 1, so that the user can push the push button 422 forward or backward to adjust the position of the charging plug 3.

[0035] In one embodiment, reference is made to Figure 4 The charging device also includes a guide structure 6, which is disposed on the inner bottom wall / side wall of the housing 1 along the first direction, and the charging circuit board 2 is movably mounted on the guide structure 6 along the first direction.

[0036] As an example, the charging device also includes a guide structure 6. During installation, the guide structure 6 is disposed on the inner bottom wall / side wall of the housing 1 along the first direction. The charging circuit board 2 is movably mounted on the guide structure 6 along the first direction. In this way, the guide structure 6 can provide guidance for the movement of the charging circuit board 2, preventing it from deviating and preventing the charging plug 3 from being misaligned and damaged with the plug hole 101.

[0037] In one embodiment, reference is made to Figure 4 The guide structure 6 includes two baffles 61 and at least one support plate 62 arranged at intervals along the second direction; the two baffles 61 are located on both sides of all the support plates 62 respectively, and the two baffles 61 and at least one support plate 62 cooperate to form a guide movement space; the charging circuit board 2 is movably installed in the guide movement space along the first direction.

[0038] As an example, the guide structure 6 includes two baffles 61 and at least one support plate 62 arranged at intervals along a second direction. When arranged, the two baffles 61 are located on both sides of all the support plates 62, and the two baffles 61 and at least one support plate 62 cooperate to form a guide movement space. The charging circuit board 2 is movably mounted in the guide movement space along a first direction. This guide movement space provides guidance for the movement of the charging circuit board 2, preventing it from shifting and avoiding misalignment or damage to the charging plug 3 and the plug hole 101. The guide structure 6 can also be configured as a guide rail.

[0039] In one embodiment, reference is made to Figure 1 and Figure 4 The charging device also includes a battery cell 7, a main circuit board 8, and a connecting wire 9. The battery cell 7 is installed inside the housing 1, and a charging hole 105 is provided on the side wall of the housing 1. The main circuit board 8 is detachably installed inside the housing 1 and electrically connected to the battery cell 7. The connector of the main circuit board 8 passes through the charging hole 105. One end of the connecting wire 9 is connected to the main circuit board 8, and the other end of the connecting wire 9 is connected to the charging circuit board 2.

[0040] As an example, the charging device also includes a battery cell 7, a main circuit board 8, and a connecting cable 9. During installation, the battery cell 7 is installed inside the housing 1 to store electrical energy. A charging hole 105 is provided on the side wall of the housing 1. The main circuit board 8 is detachably installed inside the housing 1 and electrically connected to the battery cell 7. The connector of the main circuit board 8 passes through the charging hole 105, which facilitates charging of the battery cell 7 through the charging hole 105. One end of the connecting cable 9 is connected to the main circuit board 8, and the other end of the connecting cable 9 is connected to the charging circuit board 2, so that the user can easily charge the item to be charged through the charging plug 3 on the charging circuit board 2. A button is also provided on the main circuit board 8, and a button hole 106 is provided on the housing 1. The button passes through the button hole 106 so that the user can press the button to control the opening or closing of the charging device.

[0041] In one embodiment, reference is made to Figure 4 The charging device also includes a support limiting member 10; the support limiting member 10 is installed on the inner bottom wall of the housing 1, and is located between the elastic switch structure 4 and the side wall of the housing 1 in the moving direction of the elastic switch structure 4; the main circuit board 8 is detachably installed on the support limiting member 10.

[0042] As an example, the charging device also includes a support limiting member 10. During installation, the support limiting member 10 is installed on the inner bottom wall of the housing 1, located between the elastic switch structure 4 and the side wall of the housing 1 in the direction of movement of the elastic switch structure 4. This arrangement allows the support limiting member 10 to limit the elastic switch structure 4, preventing it from moving beyond its limits and colliding with the housing 1. Additionally, the main circuit board 8 is detachably mounted on the support limiting member 10. Specifically, the main circuit board 8 is mounted on the support limiting member 10 using methods such as snap-fit, adhesive, magnetic attraction, or bolt connection. For example, the support limiting member 10 has a first mounting hole, and the main circuit board 8 has a second mounting hole. Bolts are used to install the main circuit board 8 in the first and second mounting holes to fix it to the support limiting member 10. Thus, the support limiting member 10 can also serve as a support, providing mounting support for the main circuit board 8. The support limiting member 10 is provided with a positioning pin 12, and the main circuit board 8 is provided with a positioning hole. When installing the main circuit board 8, the positioning pin 12 is inserted into the positioning hole to provide positioning for the installation of the main circuit board 8, limit the displacement of the main circuit board 8 in the horizontal direction, and prevent the main circuit board 8 from being installed incorrectly. The support limiting member 10 is a columnar structure, and there are two of them. The two support limiting members 10 are arranged at intervals along the second direction, respectively on both sides of the charging circuit board 2.
