In order to extend the service life, the existing power supply main unit often uses a rechargeable battery as the power supply. When charging the battery of this power supply main unit, the interface component of the power supply main unit needs to be connected to the external power supply device to complete the charging. However, the sockets of the existing interface components are all exposed, which makes it easy for the interface components to get water or dust, affecting the safety of the product. Summary of the invention

[0006] When the telescopic interface assembly extends out of the shell under the action of external force, the transmission assembly can drive the sliding cover to move to open the socket of the telescopic interface assembly; when the telescopic interface assembly retracts into the interior of the shell under the action of external force, the transmission assembly can drive the sliding cover to move to cover the socket of the telescopic interface assembly.

[0009] Further, the elastic member body includes a spiral portion, a fixed force arm, and a force - applying force arm.

The end of the fixed force arm away from the spiral portion is connected to the fixed end, and the end of the force - applying force arm away from the spiral portion is connected to the mobile end.

[0010] When the telescopic interface component is in the retracted state, the fixed force arm and the force - applying force arm are arranged in a crossed manner; when the telescopic interface component is in the extended state, the fixed force arm and the force - applying force arm are in a non - crossed state.

[0011] Further, the fixed end is movably connected to the housing, and the mobile end is movably connected to the telescopic interface component.

The charging interface is connected to the transmission component.

[0013] Further, the transmission component includes a gear. The gear is rotatably connected to the housing, the gear can rotate around the central axis of the gear within the housing, and the telescopic interface component and the sliding cover are respectively meshed with the gear.

[0014] Further, the transmission component includes a rotating shaft. The rotating shaft is fixed inside the housing, the rotating shaft is connected to the gear, and the gear can rotate around the rotating shaft.

[0015] Further, the housing includes an outer shell and a bottom cover. The outer shell and the bottom cover cooperate to form a receiving cavity.

[0016] Further, the sliding cover is installed in the inner cavity of the housing, and the bottom cover is connected with a sealing member.

[0021] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

The transmission component is respectively connected to the telescopic interface component and the sliding cover, so that the sliding cover and the telescopic interface component are linked. When the telescopic interface component is not needed, the telescopic interface component can retract into the interior of the housing and drive the sliding cover to automatically cover the socket of the telescopic interface component, so as to prevent impurities such as water, oil, and dust from entering the socket of the telescopic interface component and ensure the safe use of the product. When the telescopic interface component needs to be used, during the process of the telescopic interface component extending out of the housing, it drives the sliding cover to move away to expose the socket of the telescopic interface component, so that the telescopic interface component can extend out of the housing to be connected to an external power supply device. Compared with the interface component in the prior art where the socket is flush with the outer side surface of the housing, after the telescopic interface component of the present application extends out of the housing, at least a part of the telescopic interface component protrudes out of the housing, so that it can be directly connected to an external power supply device without the need to connect other connecting wires (such as a USB wire) additionally, making the charging operation more convenient.

Detailed implementation manners

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0035] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] An embodiment of this application provides a charging port protection structure. Refer to Figures 1 to 6 , Figures 1 to 6 This is the first embodiment provided by this application. In this embodiment, the charging port protection structure includes a housing 100, a telescopic interface assembly 200, a transmission assembly 300, and a sliding cover 400. The telescopic interface assembly 200 is movably connected inside the housing 100, and the telescopic interface assembly 200 can extend out of and retract into the housing 100 under the action of an external force; the transmission assembly 300 is installed inside the housing 100, and the transmission assembly 300 is respectively connected to the telescopic interface assembly 200 and the sliding cover 400. The transmission assembly 300 is used to transmit power to the sliding cover 400 under the drive of the telescopic interface assembly 200, so that the sliding cover 400 moves relative to the housing 100.

[0037] Wherein, when the telescopic interface assembly 200 extends out of the housing 100 under the action of an external force, the transmission assembly 300 can drive the sliding cover 400 to move to open the socket of the telescopic interface assembly 200; when the telescopic interface assembly 200 retracts into the housing 100 under the action of an external force, the transmission assembly 300 can drive the sliding cover 400 to move to cover the socket of the telescopic interface assembly 200.

[0038] It can be understood that the working principle of this charging port protection structure is as follows:

[0039] The telescopic interface component 200 can extend out of the housing 100 under the action of an external force and retract into the interior of the housing 100 under the action of an external force. When the user needs to use the telescopic socket component, an external force can be applied to the telescopic interface component 200. When the telescopic interface component 200 moves in the direction of extending out of the housing 100 under the action of an external force, the telescopic interface component 200 drives the transmission component 300 to move, and then the transmission component 300 transmits power to the sliding cover 400, enabling the sliding cover 400 to move relative to the housing 100. After the sliding cover 400 moves, the socket of the telescopic interface component 200 is exposed, so that the telescopic interface component 200 can extend out of the housing 100 and the telescopic interface component 200 can be connected to an external power supply device through the socket; when the user does not need to use the telescopic socket component, an external force in the reverse direction can also be applied to the telescopic interface component 200, causing the telescopic interface component 200 to move in the direction of retracting into the interior of the housing 100 (i.e., moving in the reverse direction) under the action of the external force. At the same time, the telescopic interface component 200 drives the transmission component 300 to move in the reverse direction, and the sliding cover 400 moves in the reverse direction relative to the housing 100 under the drive of the transmission component 300. After the telescopic interface component 200 retracts into the interior of the housing 100, the sliding cover 400 also moves to the corresponding position of the socket of the telescopic interface component 200 to cover the socket of the telescopic interface component 200.

[0040] Compared with the prior art, the charging port protection structure has at least the following technical effects:

[0041] The charging port protection structure provided by the embodiment of the present application can move the telescopic interface component 200 relative to the housing 100 under the action of an external force by setting the telescopic interface component 200, so that the telescopic interface component 200 can extend out of the housing 100 and retract into the housing 100 according to the user's usage requirements. By setting the transmission component 300 to be connected to the telescopic interface component 200 and the sliding cover 400 respectively, linkage between the sliding cover 400 and the telescopic interface component 200 is realized. When the telescopic interface component 200 is not needed, the telescopic interface component 200 can retract into the interior of the housing 100 and drive the sliding cover 400 to cover the socket of the telescopic interface component 200 to prevent impurities such as water, oil, and dust from entering the socket of the telescopic interface component 200, ensuring the safe use of the product. When the telescopic interface component 200 needs to be used, during the process of the telescopic interface component 200 extending out of the housing 100, it drives the sliding cover 400 to move away to expose the socket of the telescopic interface component 200, enabling the telescopic interface component 200 to extend out of the housing 100 and be connected to an external power supply device. Compared with the interface component in the prior art where the socket is flush with the outer side of the housing 100, after the telescopic interface component 200 of the present application extends out of the housing 100, at least a part of the telescopic interface component 200 protrudes from the housing 100, so that it can be directly connected to an external power supply device without the need to connect other connecting wires (such as a USB wire) additionally, making the charging operation more convenient.

[0042] In one embodiment, referring to Figures 1 to 6 , the protection structure of the charging interface 220 further includes an elastic member. The elastic member is installed inside the housing 100. The elastic member includes an elastic member body 510, a fixed end 520 and a mobile end 530 respectively connected to both ends of the elastic member body 510. The fixed end 520 is connected to the housing 100, and the mobile end 530 is connected to the telescopic interface assembly 200.

[0043] Referring to Figures 2 - 3 and Figures 5 - 6 , when the telescopic interface assembly 200 extends out of the housing 100 under an external force, the mobile end 530 can apply a thrust force towards the outside of the housing 100 to the telescopic interface assembly 200, so as to pop the telescopic interface assembly out of the housing; referring to Figures 1 - 2 and Figures 4 - 5 , when the telescopic interface assembly 200 retracts into the housing 100 under an external force, the mobile end 530 can apply a thrust force towards the inside of the housing 100 to the telescopic interface assembly 200, so as to push the telescopic interface assembly into the housing.

[0044] Specifically, the mobile end 530 on the elastic member body 510 moves relative to the housing 100 together with the telescopic interface assembly 200 driven by the movement of the telescopic interface assembly 200. The fixed end 520 on the elastic member body 510 is connected to the housing 100, and the position of the fixed end 520 in the housing 100 remains unchanged. Thus, relative movement is formed between both ends of the elastic member body 510, enabling the elastic member body 510 to deform when the external force drives the telescopic interface assembly 200. After the deformation of the elastic member body 510 reaches the critical point, the elastic member body 510 will release energy opposite to that before reaching the deformation critical point to the telescopic interface assembly 200 through the mobile end 530, so that the telescopic interface assembly 200 is subjected to two different-direction thrust forces before and after the deformation critical point of the elastic member body 510.

[0045] It can be understood that during the two processes of the telescopic interface component 200 extending out of and retracting into the housing 100 under an external force, the elastic member body 510 deforms, and the deformation and the generation of the thrust are as follows: During the process of the telescopic interface component 200 extending out of the housing 100, before the deformation of the elastic member body 510 reaches the critical point, the elastic member body 510 applies a thrust towards the inside of the housing 100 to the telescopic interface component 200 through the mobile end 530, so as to prevent the telescopic interface component 200 from being accidentally touched and ejected. At this time, the mobile end 530 continues to move in the direction of extending out of the housing. After the deformation of the elastic member body 510 reaches the critical point, the elastic member body 510 applies a thrust towards the outside of the housing 100 to the telescopic interface component 200 through the mobile end 530; During the process of the telescopic interface component 200 retracting into the housing 100, before the deformation of the elastic member body 510 reaches the critical point, the elastic member body 510 applies a thrust towards the outside of the housing 100 to the telescopic interface component 200 through the mobile end 530, so as to prevent the telescopic interface component 200 from being easily retracted into the housing, which affects the insertion with an external power supply device. At this time, the mobile end 530 continues to move in the direction of retracting into the housing. When the deformation of the elastic member body 510 reaches the critical point, the elastic member body 510 applies a thrust towards the inside of the housing 100 to the telescopic interface component 200 through the mobile end 530.

[0046] It can be understood that since the elastic member body 510 has a certain amount of deformation by itself, the critical point of the deformation of the elastic member body 510 can change the direction of the force applied by the mobile end to the telescopic interface component 200. So that during the processes of the telescopic interface component 200 extending out of and retracting into the housing 100, the telescopic interface component 200 can be subjected to two different-direction boosting forces provided by the elastic member 500, and the semi-automatic ejection and semi-automatic pushing-in of the telescopic interface component 200 can be realized, making the removal and storage of the telescopic interface component 200 more labor-saving and convenient, and also enabling the telescopic interface component 200 to extend more completely.

[0047] In this embodiment, the elastic member body 510 includes a spiral portion 511, a fixed force arm 512, and a force-applying force arm 513. The fixed force arm 512 and the force-applying force arm 513 are respectively connected to both ends of the spiral portion 511. One end of the fixed force arm 512 away from the spiral portion 511 is connected to the fixed end 520, and one end of the force-applying force arm 513 away from the spiral portion 511 is connected to the mobile end 530.

[0048] When the telescopic interface component 200 is in the retracted state, the fixed force arm 512 and the force-applying force arm are arranged in a crossed manner; when the telescopic interface component 200 is in the extended state, the fixed force arm 512 and the force-applying force arm are in a non-crossed state.

[0049] In this embodiment, the free angle of the elastic member is less than 180°. The elastic member is a torsion spring. When there is no load on the elastic member, the included angle between the fixed force arm 512 and the force - applying force arm 513 is less than 180°. Among them, the fixed force arm 512 and the fixed end 520 form a first connection end connected to the housing 100, the force - applying force arm 513 and the moving end 530 form a second connection end connected to the telescopic interface assembly 200, and the spiral part 511 forms a free end. That is, the spiral part 511 is not connected to other components except being connected to the fixed force arm 512 and the force - applying force arm 513. Thus, the spiral part 511 at the end of the force - applying force arm 513 away from the moving end 530 will also generate a certain displacement with the movement of the moving end 530.

[0050] Specifically, when the telescopic interface assembly 200 moves in the direction of extending out of the housing 100 under an external force, the force - applying force arm is first compressed and deformed under the external force, generating damping for the movement of the telescopic interface assembly 200 in the direction of extending out of the housing 100. The force - applying force arm stores energy through compression deformation until the moving end 530 continues to move in the direction of extending out of the housing 100. When the force - applying force arm reaches the deformation critical point, the force - applying force arm releases the energy in the direction of extending out of the housing 100 to the telescopic interface assembly 200, and the deformation of the force - applying force arm is restored, and the included angle between the force - applying force arm and the fixed force arm 512 is less than 180°.

[0051] When the telescopic interface assembly 200 moves in the direction of retracting into the housing 100 under an external force, the force - applying force arm is first compressed and deformed under the external force, generating damping for the movement of the telescopic interface assembly 200 in the direction of retracting into the housing 100. The force - applying force arm stores energy through compression deformation until the moving end 530 continues to move in the direction of retracting into the housing 100. When the force - applying force arm reaches the deformation critical point, the force - applying force arm releases the energy in the direction of retracting into the housing 100 to the telescopic interface assembly 200, and the deformation of the force - applying force arm is restored, and the force - applying force arm and the fixed force arm 512 are arranged in a crossed manner.

[0052] In the embodiment of the present application, through the movement and compression deformation of the force - applying force arm, and then releasing energy, the telescopic interface assembly 200 is damped in the initial stages of both extending out of the housing 100 and retracting into the housing 100, avoiding the telescopic movement of the telescopic interface assembly 200 due to accidental touch. When the external force received by the telescopic interface assembly 200 overcomes the damping effect, the force - applying force arm can provide a boosting force for the movement of the telescopic interface assembly 200.

[0053] In this embodiment, the fixed end 520 is movably connected to the housing 100, and the moving end 530 is movably connected to the telescopic interface assembly 200. Specifically, the fixed end 520 is rotatably connected to the housing 100, and the moving end 530 is rotatably connected to the telescopic interface assembly 200.

[0054] Refer to Figures 1 to 6, in this embodiment, a cylindrical first protrusion 700 is provided inside the housing 100. The first protrusion 700 is fixedly connected to the housing 100. The fixed end 520 is sleeved outside the first protrusion 700 and is rotatably connected to the first protrusion 700. It can be understood that the fixed end 520 can rotate relative to the first protrusion 700 around the central axis of the first protrusion 700, and the position of the fixed end 520 in the housing 100 remains unchanged all the time.

[0055] In this embodiment, a cylindrical second protrusion 800 is provided outside the telescopic interface assembly 200. The second protrusion 800 is fixedly connected to the telescopic interface assembly 200. The mobile end 530 is sleeved outside the second protrusion 800 and is rotatably connected to the second protrusion 800. It can be understood that the mobile end 530 can rotate relative to the second protrusion 800 around the central axis of the second protrusion 800, and the mobile end 530 can move with the telescopic interface assembly 200 and generate a relative displacement with the fixed end 520.

[0056] In one embodiment, the telescopic interface assembly 200 includes a slider 210 and a charging interface 220. The slider 210 is movably connected to the housing 100. At least a part of the slider 210 is exposed outside the housing 100. The slider 210 can move relative to the housing 100 under the action of an external force. The charging interface 220 is fixedly connected to the slider 210. The charging interface 220 can extend out of and retract into the housing 100 under the drive of the slider 210. The charging interface 220 is connected to the transmission assembly 300.

[0057] In this embodiment, the charging interface 220 is a USB interface. In some other embodiments, the charging interface 220 can also be other interface structures that can realize an electrical connection with an external power supply device.

[0058] In this embodiment, the user can push the slider 210 to push the charging interface 220 out of the housing 100 or push the charging interface 220 into the housing 100.

[0059] In this embodiment, the mobile end 530 of the elastic member body 510 is connected to the charging interface 220. The transmission assembly 300 is connected to the charging interface 220.

[0060] In one embodiment, the transmission assembly 300 includes a gear 310. The gear 310 is rotatably connected to the housing 100. The gear 310 can rotate around the central axis of the gear 310 inside the housing 100. The telescopic interface assembly 200 and the sliding cover 400 are respectively meshed with the gear 310.

[0061] In this embodiment, the transmission assembly 300 includes a rotating shaft 320. The rotating shaft 320 is fixed inside the housing 100. The rotating shaft 320 is connected to the gear 310. The gear 310 can rotate around the rotating shaft 320.

[0062] In this embodiment, the gear 310 rotates relative to the housing 100 inside the housing 100 through the rotating shaft 320. The telescopic interface assembly 200 meshes with the gear 310, so that when the telescopic interface assembly 200 moves, the gear 310 also rotates accordingly. During the rotation of the gear 310, the sliding cover 400 meshing with the gear 310 is driven by the gear 310 to generate a displacement, thereby realizing the linkage of the telescopic interface assembly 200 and the sliding cover 400. In this embodiment, the gear 310 meshes with the outside of the charging interface 220 in the telescopic interface assembly 200, and the moving direction of the sliding cover 400 is perpendicular to the moving direction of the telescopic interface assembly 200.

[0063] In some embodiments, a clamping structure (not shown in the figure) that cooperates with the inner wall of the housing 100 is provided on the side of the charging interface 220 away from the gear 310. When the charging interface 220 retracts to the position where the clamping structure and the inner wall of the housing 100 are clamped and matched with each other, through the cooperation of the clamping structure and the housing wall, the charging interface 220 can be locked in the housing 100, thereby further improving the stability of the charging interface 220 inside the housing 100 and preventing the charging interface 220 from being pushed out of the housing 100 due to accidental touch; when the charging interface 220 extends to the position where the clamping structure and the inner wall of the housing 100 are clamped and matched with each other, through the cooperation of the clamping structure and the inner wall of the housing, the charging interface 220 can be locked outside the housing 100, thereby further improving the stability of the charging interface 220 when it extends out of the housing, enabling the charging interface to be more stably connected to an external power supply device, and the charging interface is not likely to retract.

[0064] Refer to Figure 7 , Figure 7 The second embodiment provided by the present application is shown in the figure. In this embodiment, the housing 100 includes an outer shell 110 and a bottom cover 120. The outer shell 110 and the bottom cover 120 cooperate to form a receiving cavity. The transmission assembly 300 and the sliding cover 400 are both arranged in the receiving cavity. The telescopic interface assembly 200 is movably connected to the outer shell 110. The bottom cover 120 is provided with an outlet 121 corresponding to the socket of the telescopic interface assembly 200. One end of the telescopic interface assembly 200 with the socket can extend out of and retract into the receiving cavity from the outlet 121. The sliding cover 400 can move relative to the bottom cover 120 under the drive of the transmission assembly 300 to open and close the outlet 121.

[0065] Specifically, the telescopic interface component 200 is telescoped through the telescopic outlet 121. The sliding cover 400 opens and closes the telescopic outlet 121 to cover the socket of the telescopic interface component 200. When the sliding cover 400 is moved away from the position of the telescopic outlet 121, the telescopic outlet 121 is opened, and the telescopic interface component 200 can extend out of the accommodation cavity; when the telescopic interface component 200 retracts into the accommodation cavity, the sliding cover 400 simultaneously moves to the position of the telescopic outlet 121 to shield the telescopic outlet 121. At this time, the telescopic outlet 121 is closed, and the socket of the telescopic interface component 200 is received in the sealed accommodation cavity.

[0066] In this embodiment, the sliding cover 400 is installed in the inner cavity of the housing 100. The bottom cover 120 is connected with a seal 600.
