[0038] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Refer to Figures 1 to 3, which show a portable energy storage power supply 100 in one embodiment, which uses a rechargeable battery to provide off-grid power. It is similar to a mobile power supply, but has a larger capacity, higher output power and an AC outlet. The power is provided in any desired form, such as low-voltage direct current, high-voltage direct current and line voltage alternating current (i.e., 120V or 240V), so it can power any device from mobile phones to household appliances. In one embodiment, the portable energy storage power supply 100 includes a housing 10 and a battery module 20 (see Figures 14 and 16), and the housing 10 is provided with a socket through hole and a mounting slot. The battery module 20 is disposed in the housing 10.

[0041] Referring to Figures 4 to 6 , in one embodiment, the portable energy storage power supply 100 further includes a socket 30 and a socket cover 40. In this embodiment, the socket 30 is a three-pin AC socket. The socket through-hole corresponding to the socket 30 is the socket through-hole 11, and the mounting slot is the mounting slot 12 located adjacent to the socket through-hole 11 (see Figure 7 ). The socket 30 is disposed within the housing 10 and exposed through the socket through-hole 11. The socket 30 is electrically connected to the battery module 20. The socket cover 40 includes a plug-in portion 41, a connecting portion 42, and a cover plate 43. The plug-in portion 41 and the cover plate 43 are connected together by the connecting portion 42. The plug-in portion 41 passes through the mounting slot 12 of the housing 10 to connect the cover plate 43 to the housing 10. The connecting portion 42 is flexible, allowing the cover plate 43 to rotate relative to the housing 10 between a closed position (see Figure 2 ) and an open position (see Figure 4 ). In the closed position, the cover plate 43 covers the socket 30.

[0042] With such a structure, the socket cover 40 can be installed on the housing 10 without additional tools, which is convenient for operators to work with their bare hands and helps to improve production efficiency.

[0043] In one embodiment, the housing 10 is generally rectangular. Referring to FIG13 , the housing 10 includes a first side panel 101, a second side panel 102, a third side panel 103, and a fourth side panel 104. The first side panel 101 and the second side panel 102 are opposite each other, and the third side panel 103 and the fourth side panel 104 are opposite each other. In the embodiment illustrated in FIG4 , the socket 30 is exposed through a socket through-hole 11 provided on the second side panel 102. In this embodiment, a generally square recess 1011 is provided on the outer surface of the second side panel 102, and the socket through-hole 11 is provided at the bottom of the recess 1011. The cover 43 is generally square and sized to precisely cover the recess 1011. In other words, in the closed position, the cover 43 covers the recess 1011, thereby concealing the socket 30. Thus, when the portable energy storage power supply 100 is not in use, the user can rotate the cover 43 to the closed position to cover and protect the socket 30. In one embodiment, the plug portion 41, the connecting portion 42, and the cover plate 43 are integrally formed from an elastically deformable material. The connecting portion 42 is connected to one long side of the cover plate 43. Compared to the plug portion 41 and the cover plate 43, the connecting portion 42 is thinner, making it easier to elastically deform, thereby allowing the cover plate 43 to rotate relative to the second side plate 102.

[0044] 7 , in one embodiment, the mounting groove 12 is provided on the bottom surface of the recess 1011 and extends along the length direction of the recess 1011 , that is, the mounting groove 12 is an elongated groove penetrating the first side plate 101 .

[0045] 4 to 7 , in one embodiment, the plug-in portion 41 includes a head portion 411, a neck portion 412, and a wedge-shaped body 413. The head portion 411 is generally slender and square, and the head portion 411 and the body 413 are connected together via the neck portion 412. The head portion 411 is connected to the connecting portion 42, and the neck portion 412 protrudes from the outer surface of the head portion 411 facing the outer shell 10. The body 413 passes through the mounting slot 12 and is located within the outer shell 10. The neck portion 412 is received in the mounting slot 12, and the head portion 411 and the body 413 respectively contact the outer surface and inner surface of the outer shell 10.

[0046] 6 and 7 , the top and bottom surfaces of the neck 412 are parallel to each other, so that the neck 412 has a consistent thickness. At the junction of the neck 412 and the head 411, the thickness of the neck 412 is less than the thickness of the head 411; at the junction of the neck 412 and the main body 413, the thickness of the neck 412 is less than the thickness of the main body 413. Through such a structure, the head 411, the neck 412, and the main body 413 are all formed with recessed portions above and below the neck 412. In this way, after the main body 413 passes through the mounting groove 12, the upper and lower edges of the mounting groove 12 are respectively accommodated in the above-mentioned recessed portions, so that the head 411 and the main body 413 respectively contact the outer surface and inner surface of the shell 10, thereby making the plug-in portion 41 connected to the shell 10 and unable to move relative to the shell 10.

[0047] Referring to Figures 6 and 7 , the main body 413 is a wedge-shaped plate, with the thickness of the main body 413 gradually increasing from the distal end away from the head 411 to the proximal end closer to the head 411. When the operator connects the socket cover 40 to the housing 10, the distal end of the main body 413 gradually approaches the mounting slot 12 and eventually moves into the mounting slot 12. Under the user's push, the main body 413 gradually passes through the mounting slot 12. During this process, because the thickness of the main body 413 gradually increases from the distal end to the proximal end, when the thickness of the main body 413 exceeds the width of the mounting slot 12, the main body 413 begins to be squeezed by the upper and lower edges of the mounting slot 12, gradually undergoing elastic deformation until the main body 413 completely passes through the mounting slot 12. Thereafter, the main body 413 returns to its original shape, with the upper and lower edges of the mounting slot 12 respectively received in the recessed portions above and below the neck 412.

[0048] Referring to Figures 8 and 9, in another embodiment, the socket 30 is an AC output socket disposed on the fourth side panel 104. For ease of description, the AC output socket is hereinafter referred to as socket 30a, and the socket cover corresponding to socket 30a is referred to as 40a. Similar to socket cover 40, socket cover 40a includes an inserting portion 41a, a connecting portion 42a, and a cover plate 43a. The inserting portion 41a and the cover plate 43a are connected together by the connecting portion 42a. The connecting portion 42a is flexible, allowing the cover plate 43a to rotate relative to the housing 10 between a closed position and an open position. In this embodiment, the main difference between the socket cover 40a and the socket cover 40 is reflected in the plug-in portion 41a. Specifically, the plug-in portion 41a is provided with a card slot 411a, and the interior of the shell 10 is provided with a card protrusion 105. After the plug-in portion 41a passes through the installation slot of the shell 10, the card protrusion 105 is accommodated in the card slot 411a, so that the plug-in portion 41a is connected to the shell 10.

[0049] When the operator connects the socket cover 40a to the housing 10, the distal end of the plug portion 41a gradually approaches the mounting slot 12 and eventually moves into the mounting slot 12. Under the user's push, the plug portion 41a gradually passes through the mounting slot 12. During this process, the plug portion 41a first contacts the engaging protrusion 105, which is formed on a resiliently deflectable cantilever. Pushed by the plug portion 41a, the cantilever deflects downward, thereby driving the engaging protrusion 105 downward until the engaging slot 411a of the plug portion 41a faces the engaging protrusion 105. Thereafter, the cantilever returns to its original shape, driving the engaging protrusion 105 into the engaging slot 411a, thereby connecting the plug portion 41a to the housing 10.

[0050] Referring to Figures 10 to 12 , in another embodiment, the socket 30 is a USB socket or a DC output socket disposed on the first side panel 101. For ease of description, the USB socket or DC output socket will be referred to as socket 30b, and the socket cover corresponding to socket 30b will be referred to as 40b. Similar to socket cover 40, socket cover 40b includes a plug portion 41b, a connecting portion 42b, and a cover plate 43b. The plug portion 41b and the cover plate 43b are connected together by the connecting portion 42b. The connecting portion 42b is flexible, allowing the cover plate 43b to rotate relative to the housing 10 between a closed position and an open position. In this embodiment, the main difference between socket cover 40b and socket cover 40 lies in the plug portion 41b. Specifically, the plug portion 41b and the plug portion 41 have very similar structures, the main difference between the two being two notches 411b formed at the distal end of the plug portion 41b, which has a smaller thickness.

[0051] Referring to Figures 13 and 14 , in one embodiment, the portable energy storage power supply 100 further includes a frame 106 disposed within the housing 10. The frame 106 includes a first support rod 1061, a second support rod 1062, a third support rod 1063, and a fourth support rod 1064 extending vertically and spaced apart from one another. The surfaces of the first support rod 1061 and the second support rod 1062 facing the third side plate 103 are each provided with receiving grooves 10610 and 10620 extending in the width direction of the frame. In this embodiment, the number of receiving grooves 10610 and 10620 is four. It is understood that the number of receiving grooves 10610 and 10620 is not limited to this and can be determined based on actual needs. Similarly, the surfaces of the third support rod 1063 and the fourth support rod 1064 facing the fourth side plate 104 are each provided with receiving grooves 10630 and 10640 extending in the width direction of the frame 106.

[0052] The inner surfaces of the first side panel 101 and the second side panel 102 each have two protrusions 1012 and 1021 protruding near the left and right edges, respectively. The protrusion 1012 of the first side panel 101 is received in the receiving grooves 10610 and 10630 of the first support rod 1061 and the third support rod 1063, respectively, and cannot move in the vertical direction. The protrusion 1021 of the second side panel 102 is received in the receiving grooves 10620 and 10640 of the second support rod 1062 and the fourth support rod 1064, respectively, and cannot move in the vertical direction. With this structure, the first side panel 101 and the second side panel 102 cannot move in the vertical direction relative to the frame 106. It is understood that the number of the above-mentioned receiving grooves and protrusions is not limited to this and can be determined according to actual needs.

[0053] With reference to Figures 13, 17, and 18 simultaneously, in one embodiment, the inner surface of the third side panel 103 facing the frame 106 has a plurality of protruding tabs protruding near the left and right sides. Due to viewing angles, the protruding tabs are not shown. The inner surface of the fourth side panel 104 facing the frame 106 has a protruding tab 1041 protruding near the left and right sides. Each of the protruding tabs has an inclined edge, and the protruding portions of the first side panel 101 and the second side panel 102 each include a through hole, for example, through hole 1013 shown in Figure 17. The protruding tabs of the third side panel 103 respectively pass through the through hole of the protruding portion of the first side panel 101 near the left side and the through hole of the protruding portion of the second side panel 102 near the left side, and the protruding tabs of the fourth side panel 104 respectively pass through the through hole of the protruding portion of the first side panel 101 near the right side and the through hole of the protruding portion of the second side panel 102 near the right side. During assembly, as the third and fourth side panels 103 and 104 move toward the frame 106, the oblique edges of the protruding pieces contact the inner surfaces of the through holes, thereby pushing the first and second side panels 101 and 102 toward the frame. With this structure, the first and second side panels 101 and 102 are fixed to the frame 106 without the need for additional fasteners (e.g., screws), which helps save costs.

[0054] 14 and 15 , in one embodiment, the portable energy storage power supply 100 further includes a support plate 107, a circuit board 108, and a fan 109 disposed within the housing 10. The support plate 107 is connected to the frame 106 and divides the frame 106 into an upper half and a lower half. Specifically, the support plate 107 is generally square in shape, and is connected at its four corners via fasteners to positions approximately midway between the first support rod 1061, the second support rod 1062, the third support rod 1063, and the fourth support rod 1064, thereby dividing the frame 106 into a hollow upper half and a hollow lower half.

[0055] The circuit board 108 is located in the hollow upper half and is mounted on the support plate 107. A fan 109 is fixed to one end of the frame 106. The fan 109 is configured to provide an airflow from a first end of the frame 106, closer to the fan 109, through the circuit board 108, and toward the other end (i.e., the second end) of the frame 106. Alternatively, the fan 109 is configured to provide an airflow from a second end of the frame 106, farther from the fan 109, through the circuit board 108, and toward the first end of the frame 106. This airflow can remove heat generated by electronic components on the circuit board 108 during operation.

[0056] Referring to FIG. 16 , in one embodiment, the circuit board 108 includes electronic components such as a filter, a rectifier, an LLC converter, and a bridgeless PFL circuit arranged along its length. To better remove heat generated by the electronic components on the circuit board 108 during operation, the portable energy storage power supply 100 further includes a flow guide 110 . The flow guide 110 includes a top plate parallel to the circuit board 108 and two side plates connected to the top plate and substantially perpendicular to the circuit board 108 . The top plate and side plates form a flow guide channel extending from the first end of the frame 106 to the second end of the frame 106 . The flow guide channel is used to guide the airflow of the fan 109 from the first end of the frame 106 to the second end of the frame 106 , or from the second end of the frame 106 to the first end of the frame 106 . This structure can improve the heat dissipation efficiency of the fan 109 .

[0057] In one embodiment, the battery module 20 is disposed in the hollow lower half of the frame 106, that is, below the support plate 107. The battery module 20 includes a plurality of batteries 21 spaced apart from each other. In this embodiment, referring to Figures 14 and 16, the battery 21 is cylindrical, and the plurality of batteries 21 extend in the vertical direction. In this embodiment, a fan 111 is provided below the fan 109, and the fan 111 is used to provide an airflow from the first end of the frame 106 close to the fan 111 through the gaps between the batteries 21 and flowing to the other end (i.e., the second end) of the frame 106, or the fan 111 is used to provide an airflow from the second end of the frame 106 away from the fan 111 through the gaps between the batteries 21 and flowing to the first end of the frame 106. This airflow can take away the heat generated by the battery 21 during operation / charging.

[0058] Referring to FIG. 19 , in one embodiment, the portable energy storage power supply 100 further includes a main controller 50 and a sensor 60 electrically connected to the main controller 50. The main controller 50 is disposed on the circuit board 108. The sensor 60 is used to detect the closing and opening of the cover 43a. When the sensor 60 detects the closing of the cover 43a, the main controller 50 disconnects the electrical connection between the socket 30a and the battery module 20 based on the signal from the sensor 60. Thus, when the user rotates the cover 43a to the closed position, indicating that the user is no longer using the socket 30a, the main controller 50 disconnects the socket 30a from the battery module 20, thereby avoiding unnecessary power loss and achieving the goal of saving electricity.

[0059] Referring to FIG9 , in one embodiment, the sensor 60 is a Hall effect sensor. A magnet 80 is embedded in the cover 43 a. When the cover 43 a is rotated to the closed position, the magnet 80 faces the Hall effect sensor 60. The Hall effect sensor 60 transmits a signal to the main controller 50, which then determines that the cover 43 a is in the closed position. It is understood that in other embodiments, other suitable types of sensors, such as optical sensors, may be used as needed.

[0060] In one embodiment, the portable energy storage power supply 100 further includes an LED lamp 70 disposed within the housing 10. Referring to FIG4 , the second side panel 102 includes a main body 1022 and a light-transmitting portion 1023 integrally formed with the main body 1022 (e.g., by double-injection molding or two-color injection molding). The light-transmitting portion 1023 allows light from the LED lamp 70 to pass through. The LED lamp 70 can provide illumination when the ambient light is insufficient. The main body 1022 and the integral molding with the main body 1022 give the second side panel 102 a more integrated feel, thereby providing a good texture.

[0061] In this embodiment, the light-transmitting portion 1023 includes two spaced-apart, elongated first and second light-transmitting portions 1024 and 1025. In one embodiment, the housing 10 further includes a touchpad 1026 located between the first and second light-transmitting portions 1024 and 1025. The touchpad 1026 is electrically connected to the main controller 50 and is capable of detecting a user's touch. The main controller 50, based on signals from the main controller 50, can recognize a user's sliding motion on the touchpad 1026 and adjust the brightness of the LED light 70 accordingly.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
