Description

Technical Field

[0001] This application relates to the field of energy storage equipment, specifically an energy storage power supply and combined equipment. Background Technology

[0002] In recent years, with the rise of the outdoor market, scenarios have emerged where energy storage power supplies are used in conjunction with other functional modules, such as energy storage power supplies paired with power banks. In related technologies, functional modules such as power banks are usually inserted into and locked in the slot of the energy storage power supply. They are then unlocked and removed from the slot when needed. While this allows the functional modules to be reliably stored inside the energy storage power supply, it also results in high structural costs and cumbersome access. Utility Model Content

[0003] In view of this, this application provides an energy storage power supply and combined device capable of fixing functional modules.

[0004] One embodiment of this application provides an energy storage power supply, including a top cover and a limiting member. The top cover is recessed to form a cavity, which is configured to accommodate a functional module. The cavity opening allows the functional module to enter and exit the cavity. The top cover has a first cavity wall and a second cavity wall facing each other within the cavity. The first cavity wall has a limiting protrusion on the side near the cavity opening. The limiting member is disposed on the second cavity wall and includes a first rib and a second rib. The first rib is located on the side of the second rib facing the cavity opening, and the cross-sectional area of ​​the second rib gradually increases from the inner side of the cavity towards the cavity opening. The first rib and the limiting protrusion press against the outer wall of the functional module facing the cavity opening towards the inner side of the cavity. The portion of the second rib near the cavity opening abuts against the outer wall of the functional module facing the second cavity wall, causing the outer wall of the functional module facing the first cavity wall to abut against the first cavity wall or the limiting protrusion. A clearance space is formed between the portion of the second rib away from the cavity opening and the outer wall of the functional module.

[0005] This application provides an energy storage power supply. A first rib and a limiting protrusion press against the functional module, restricting its movement along the depth of the chamber. A second rib, near the chamber opening, abuts against the functional module, causing it to abut against the first chamber wall or the limiting protrusion. This further restricts the functional module's movement perpendicular to the chamber depth, improving its stability within the chamber and reducing the risk of it falling or being lost. Furthermore, a clearance space is formed between the portion of the second rib away from the chamber opening and the outer wall of the functional module. This clearance space provides room for the functional module to move when it is removed, making it easier to remove and preventing excessive force from the second rib pressing against the module, thus achieving effortless operation and significantly improving the user experience.

[0006] In some embodiments, the limiting member has a plurality of second ribs, each second rib extending along the depth direction of the cavity, the plurality of second ribs being arranged at intervals along a direction perpendicular to the depth direction of the cavity, a first rib extending along a direction perpendicular to the plurality of second ribs, and the top end of each second rib being connected to the first rib.

[0007] In some embodiments, the first rib has a pressing surface and a guiding surface disposed opposite to each other. The guiding surface is inclined toward the cavity opening and configured to guide at least a portion of the functional module to move below the pressing surface. The pressing surface is configured to press against the outer wall of the functional module toward the inner side of the cavity to confine the functional module within the cavity.

[0008] In some embodiments, the limiting protrusion extends along the first cavity wall at the edge of the cavity opening, and the first cavity wall has a groove on the side of the limiting protrusion facing the cavity. The groove extends along the limiting protrusion, and a plurality of spaced connecting ribs are provided in the groove. The connecting ribs connect the limiting protrusion and the first cavity wall.

[0009] In some embodiments, the limiting member further includes a main body and a mounting part. The second cavity wall is provided with a mounting groove, and the bottom wall of the mounting groove is provided with a through hole. The mounting groove accommodates the main body. The first rib and the second rib are provided on the side of the main body facing the cavity. The mounting part is provided on the side of the main body facing the through hole and is inserted into the through hole. The end of the mounting part away from the main body is provided with a stop protrusion. The stop protrusion and the main body clamp the hole wall of the through hole to fix the main body in the mounting groove.

[0010] In some embodiments, the side of the stop protrusion away from the main body is provided with a first guide surface, and the wall of the through hole is provided with a second guide surface. When the stop protrusion extends into the through hole, the first guide surface abuts against the second guide surface to guide the stop protrusion through the through hole.

[0011] In some embodiments, the second cavity wall is recessed on the side opposite to the cavity to form a clearance notch, which is used to expose at least a portion of the outer wall of the functional module facing the second cavity wall.

[0012] In some embodiments, the second cavity wall is provided with two limiting members, which are respectively located on opposite sides of the clearance notch.

[0013] In some embodiments, the first cavity wall is provided with an electrical connector configured to insert a functional module toward the second cavity wall, so that the energy storage power supply is electrically connected to the functional module.

[0014] In one embodiment of this application, a combined device is also provided, which includes a functional module and an energy storage power supply as described in any of the above embodiments. The energy storage power supply is electrically connected to the functional module and charges the functional module.

[0015] In the combined device provided by this application, the first rib and the limiting protrusion press against the functional module, restricting the movement of the functional module along the depth direction of the cavity. Furthermore, the portion of the second rib near the cavity opening abuts against the functional module, causing the functional module to abut against the first cavity wall or the limiting protrusion, thereby restricting the movement of the functional module along the direction perpendicular to the cavity depth. This improves the stability of the functional module within the cavity and reduces the risk of the functional module falling or being lost. In addition, a clearance space is formed between the portion of the second rib away from the cavity opening and the outer wall of the functional module. This clearance space provides space for the functional module to move when it is removed, making it easier to remove and avoiding excessive force from the second rib abutting against the functional module, which would otherwise make removal difficult and improve the user experience.

[0030] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

When a component is considered to be "connected to" another component, it can be directly connected to the other component or may have an intervening component. When a component is considered to be "set on" another component, it can be directly set on the other component or may have an intervening component. The terms "vertical" or "horizontal" and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In recent years, with the rise of the outdoor market, scenarios have emerged where energy storage power supplies are used in conjunction with power banks. In related technologies, the power bank is usually inserted into the slot of the energy storage power supply and then removed from the slot when needed. However, currently, there is often a problem that the power bank is not securely fixed after being inserted into the slot of the energy storage power supply. When the energy storage power supply is lifted, the power bank is prone to tipping over and falling out, causing the charging function of the energy storage power supply to fail.

[0034] In view of this, this application provides an energy storage power supply and combined device capable of fixing functional modules. The energy storage power supply includes a top cover and a limiting member. The top cover is recessed to form a cavity, which is configured to accommodate the functional module. The cavity opening allows the functional module to enter and exit the cavity. The top cover has opposing first and second cavity walls within the cavity. The first cavity wall has a limiting protrusion on the side near the cavity opening. The limiting member is located on the second cavity wall and includes a first rib and a second rib. The first rib is located on the side of the second rib facing the cavity opening, and the cross-sectional area of ​​the second rib gradually increases from the inside of the cavity towards the cavity opening. The first rib and the limiting protrusion press against the outer wall of the functional module facing the cavity opening towards the inside of the cavity. The portion of the second rib near the cavity opening abuts against the outer wall of the functional module facing the second cavity wall, causing the outer wall of the functional module facing the first cavity wall to abut against the first cavity wall or the limiting protrusion. A clearance space is formed between the portion of the second rib away from the cavity opening and the outer wall of the functional module.

[0035] This application provides an energy storage power supply. A first rib and a limiting protrusion press against the functional module, restricting the module's movement along the depth of the chamber. A second rib, near the chamber opening, abuts against the functional module, causing it to abut against the first chamber wall or the limiting protrusion. This further restricts the module's movement perpendicular to the chamber depth, improving its stability within the chamber and reducing the risk of it falling or being lost. Furthermore, a clearance space is formed between the portion of the second rib away from the chamber opening and the outer wall of the functional module. This clearance space provides room for the module to move when removed, making it easier to remove and preventing excessive force from the second rib abutting the module, thus improving the user experience.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Some embodiments of this application provide a combined device 200, such as... Figures 1 to 3 As shown, the combined device 200 includes a functional module 300 and an energy storage power supply 100. The functional module 300 is detachably housed within the energy storage power supply 100. When the functional module 300 is housed within the energy storage power supply 100, the functional module 300 is electrically connected to the energy storage power supply 100, and the energy storage power supply 100 can charge the functional module 300. The functional module 300 can be a power bank, which has a charging section 301 for electrically connecting to and charging a mobile terminal (such as a mobile phone or tablet). The functional module 300 can also be a lighting device, a drone, or a mobile phone holder, etc.

[0038] For example, the energy storage power supply 100 can be a portable power source for outdoor use, or a home energy storage system for home use. The functional module 300 can be a portable charger, such as a power bank, and the charging part 301 can be the wireless charging plane area of ​​the power bank, or a slot or pin (such as a Pogopin) of the power bank.

[0039] In some embodiments, such as Figures 3 to 5 As shown, the energy storage power supply 100 includes a top cover 10 and a limiting member 20. The top cover 10 is recessed to form a cavity 11, which is used to accommodate at least part of the functional module 300. The cavity 11 extends through the top of the top cover 10 to form an opening 12, which is used to expose the charging part 301 of the functional module 300. The top cover 10 has opposing first cavity walls 13 and second cavity walls 14 formed in the cavity 11. The first cavity wall 13 has a limiting protrusion 131 on the side near the opening 12. The limiting member 20 is provided on the second cavity wall 14 and includes a first rib 21 and a second rib 22. The first rib 21 is located on the side of the second rib 22 facing the opening 12.

[0040] The first rib 21 and the limiting protrusion 131 are used together to press against the outer wall of the functional module 300 facing the cavity opening 12 in the direction of the inner side of the cavity 11, so as to press the functional module 300 to the bottom surface of the cavity 11, thereby restricting the movement of the functional module 300 along the depth direction of the cavity 11.

[0041] The cross-sectional area of ​​the second rib 22 gradually increases from the inner side of the cavity 11 towards the cavity opening 12. The portion of the second rib 22 near the cavity opening 12 abuts against the outer wall of the functional module 300 facing the second cavity wall 14, causing the functional module 300 to abut against the outer wall of the first cavity wall 13 or the limiting protrusion 131. That is, the second rib 22, the first cavity wall 13, and / or the limiting protrusion 131 clamp the functional module 300, thereby restricting the movement of the functional module 300 along the direction perpendicular to the depth of the cavity 11. The portion of the second rib 22 away from the cavity opening 12 forms a clearance space 221 between itself and the outer wall of the functional module 300. This clearance space 221 provides space for the functional module 300 to move when it is removed, making it easier to remove and avoiding excessive force from the second rib 22 abutting against the functional module 300, which would make removal more difficult.

[0042] In summary, the energy storage power supply 100 improves the stability of the functional module 300 within the chamber 11 through the limiting protrusion 131, the first rib 21, and the second rib 22, thereby making the functional module 300 more stably housed within the energy storage power supply 100 and reducing the risk of the functional module 300 falling or being lost. At the same time, the energy storage power supply 100 also makes it easier to remove the functional module 300 through the clearance space 221, thereby improving the user experience.

[0043] In addition, such as Figure 1 As shown, the energy storage power supply 100 exposes the charging section 301 of the functional module 300 through the cavity opening 12 of the chamber 11, so that the functional module 300 can be stored while charging mobile terminals such as mobile phones can be charged through the charging section 301 without having to completely remove the functional module 300, which improves the ease of use of the functional module 300. Furthermore, when the functional module 300 is charging the mobile terminal, the mobile terminal can also be stably supported on the energy storage power supply 100, reducing the risk of the functional module 300 and the mobile terminal falling or being lost during the transportation of the energy storage power supply 100.

[0044] In some embodiments, such as Figure 3 and Figure 6 As shown, the limiting member 20 has a plurality of second ribs 22, each of which extends along the depth direction of the cavity 11. The plurality of second ribs 22 are arranged at intervals along a direction perpendicular to the depth direction of the cavity 11, thereby more evenly abutting against the outer wall of the functional module 300, improving the stability of the functional module 300. Furthermore, the gap between two adjacent second ribs 22 can provide deformation space for the second ribs 22, which is beneficial to the deformation of the plurality of second ribs 22. The first rib 21 extends along a direction perpendicular to the plurality of second ribs 22, and the top end of each second rib 22 is connected to the first rib 21, thereby improving the connection strength between the first rib 21 and the second rib 22.

[0045] Further optional, such as Figure 7 As shown, multiple second ribs 22 can be connected along the depth direction perpendicular to the cavity 11 to form an integral second rib 22, thereby further improving the structural strength.

[0046] In some embodiments, such as Figure 3 and Figure 6 As shown, the first rib 21 has a pressing surface 211 and a guiding surface 212 arranged opposite to each other. The guiding surface 212 is inclined toward the cavity 12 and is used to guide at least part of the functional module 300 to move below the pressing surface 211. The pressing surface 211 is used to press against the outer wall of the functional module 300 toward the inner side of the cavity 11 to press the functional module 300 against the bottom surface of the cavity 11, thereby restricting the movement of the functional module 300 along the depth direction of the cavity 11.

[0047] Specifically, when the functional module 300 is stored, after the outer wall of the functional module 300 contacts the guide surface 212, as the user presses the functional module 300 towards the inside of the cavity 11, at least a portion of the functional module 300 slides along the guide surface 212 towards the underside of the pressure contact surface 211. Simultaneously, the first protruding rib 21 is deformed under pressure until at least a portion of the functional module 300 slides below the pressure contact surface 211. The first protruding rib 21 then elastically recovers, causing the pressure contact surface 211 to press against the outer wall of the functional module 300 below. This restricts the movement of the functional module 300 along the depth direction of the cavity 11, reducing the risk of the functional module 300 detaching from the cavity 11. For example, the first protruding rib 21 is made of an elastic material, such as rubber or silicone.

[0048] Optionally, such as Figure 2 , Figure 3 and Figure 6 As shown, the thickness of the functional module 300 is greater than or equal to the depth of the cavity 11. A flange 302 is provided on the periphery of the functional module 300. When the functional module 300 is housed in the cavity 11, the flange 302 is located below the limiting protrusion 131 and the pressure contact surface 211. The limiting protrusion 131 and the pressure contact surface 211 are used to press against the flange 302 to limit the functional module 300. Alternatively, the thickness of the functional module 300 may be less than the depth of the cavity 11. When the functional module 300 is housed in the cavity 11, the limiting protrusion 131 and the pressure contact surface 211 can press against the top surface of the functional module 300. In this case, the flange 302 can be omitted to simplify the structure of the functional module 300.

[0049] In some embodiments, such as Figure 4 and Figure 8 As shown, the limiting protrusion 131 extends along the first cavity wall 13 at the edge of the cavity opening 12. The first cavity wall 13 has a groove 132 on the side of the limiting protrusion 131 facing the cavity 11. The groove 132 extends along the limiting protrusion 131 and is used to provide deformation space for the limiting protrusion 131, so that the limiting protrusion 131 can be appropriately deformed when picking up and placing the functional module 300, so as to pick up and place the functional module 300 more smoothly.

[0050] Optionally, the groove 132 is provided with a plurality of spaced connecting ribs 133, which connect the limiting protrusion 131 and the first cavity wall 13 to improve the connection strength between the limiting protrusion 131 and the first cavity wall 13 and reduce the risk of the limiting protrusion 131 breaking at the groove 132.

[0051] In some embodiments, such as Figure 3 , Figure 6 and Figure 9As shown, the limiting member 20 also includes a main body 23, which is sheet-shaped. The first rib 21 and the second rib 22 are both located on the same side of the main body 23. The second cavity wall 14 is provided with a mounting groove 141, which is used to accommodate the main body 23 for mounting the limiting member 20 and to prevent the main body 23 from protruding from the cavity 11, thus avoiding interference of the main body 23 with the placement and removal of the functional module 300.

[0052] In some embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the limiting member 20 also includes a mounting part 24. The bottom wall of the mounting groove 141 is provided with a through hole 142. The mounting part 24 is located on the side of the main body 23 facing the through hole 142 and is inserted into the through hole 142. The end of the mounting part 24 away from the main body 23 is provided with a stop protrusion 25. The stop protrusion 25 is located on the side of the bottom wall of the mounting groove 141 away from the main body 23. The stop protrusion 25 and the main body 23 clamp the hole wall of the through hole 142 to fix the main body 23 in the mounting groove 141.

[0053] In some embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the stop protrusion 25 has a first guide surface 251 on the side facing away from the main body 23, and a second guide surface 143 on the side of the through hole 142 facing the cavity 11. When the stop protrusion 25 extends into the through hole 142, the first guide surface 251 and the second guide surface 143 abut against each other to guide the stop protrusion 25 through the through hole 142. Specifically, the second guide surface 143 compresses the first guide surface 251, causing the stop protrusion 25 to be compressed and deformed until the stop protrusion 25 passes through the through hole 142. The stop protrusion 25 then elastically recovers its shape to prevent the mounting part 24 from dislodging from the through hole 142, thereby fixing the main body 23 in the mounting groove 141. For example, the stop protrusion 25 is made of an elastic material, such as rubber or silicone.

[0054] Alternatively, the main body 23, the first rib 21, the second rib 22, the mounting part 24, and the stop protrusion 25 are integrally molded by injection molding to improve production efficiency.

[0055] In some other embodiments, the main body 23 is provided with adhesive on the side facing away from the first rib 21 and the second rib 22, and the bottom surface of the mounting groove 141 has a flat bonding area. The main body 23 is attached to the bonding area by adhesive to install the limiting member 20 to the second cavity wall 14. At this time, the mounting part 24 and the stop protrusion 25 can be eliminated to simplify the structure of the limiting member 20.

[0056] In some embodiments, such as Figure 2 , Figure 3 and Figure 9As shown, the second cavity wall 14 is recessed on the side opposite to the cavity 11 to form a clearance notch 15. The clearance notch 15 is used to expose at least part of the outer wall of the functional module 300 facing the second cavity wall 14, so that when the functional module 300 is removed from the cavity 11, the user can apply force to the functional module 300 by hand or by using a tool in the clearance notch 15 to remove the functional module 300.

[0057] In some embodiments, such as Figure 2 , Figure 3 and Figure 9 As shown, the clearance notch 15 is located in the middle of the second cavity wall 14. The second cavity wall 14 is provided with two limiting members 20, which are respectively located on opposite sides of the clearance notch 15, so as to press the outer wall of the functional module 300 more evenly and improve the stability of the functional module 300.

[0058] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the first cavity wall 13 is provided with an electrical connector 16. The electrical connector 16 is inserted into the functional module 300 towards the second cavity wall 14, so that the energy storage power supply 100 is electrically connected to the functional module 300 to charge the functional module 300. Since the second protrusion 22 of the limiting member 20 abuts against the functional module 300 towards the first cavity wall 13, the limiting member 20 applies a pushing force to the functional module 300 towards the electrical connector 16, making the side insertion of the functional module 300 and the electrical connector 16 more stable, reducing the risk of the functional module 300 detaching from the electrical connector 16, and improving the electrical connection stability between the functional module 300 and the electrical connector 16.

[0059] For example, the electrical connector 16 is a Pogopin spring pin, and the functional module 300 is provided with a slot 303 corresponding to the electrical connector 16. In other embodiments, the electrical connector 16 and the slot 303 may also be other structures, such as interfaces or contacts.

[0060] In some embodiments, a water inlet detection port (not shown) is provided in the chamber 11, which is connected to the chamber 11. The energy storage power supply 100 is equipped with a detector (not shown) inside the water inlet detection port. The detector is used to detect whether water has entered the chamber 11, and disconnects the electrical connection between the electrical connector 16 and the functional module 300 when water enters the chamber 11, thereby reducing the risk of short circuits. Specifically, when water enters the chamber 11, for example when the energy storage power supply 100 is outdoors in rainy weather, the water in the chamber 11 will flow into the water inlet detection port, causing the detector to detect the water inlet in the chamber 11, thereby disconnecting the electrical connection between the electrical connector 16 and the functional module 300. Exemplarily, the water inlet detection port can be provided in the first cavity wall 13, the second cavity wall 14, or the bottom wall of the chamber 11, etc.

[0061] In some embodiments, such as Figure 3 As shown, the bottom wall of the chamber 11 is the bottom wall 17. The bottom wall 17 is inclined so that the water carried by the bottom wall 17 can flow naturally to the water inlet detection port by gravity, so that the detector can detect whether water has entered the chamber 11 more quickly and reduce the risk of water accumulation in the chamber 11.

[0062] In some embodiments, the cavity bottom wall 17 is inclined, and the inclined cavity bottom wall 17 is used to support the charging unit 301 of the functional module 300 at a preset angle, so that the mobile terminal located in the charging unit 301 is also supported at the preset angle. The display screen of the mobile terminal located at the preset angle is easily viewable by the user, so the cavity bottom wall 17 acts as a support, allowing the user to view the mobile terminal's display screen from a better viewing angle. Specifically, for example, the cavity bottom wall 17 can support the mobile phone located on the charging unit 301 at approximately 45 degrees, so that the user can view the screen display while the phone is charging.

[0063] Optionally, the top cover 10 is provided with a flip-up member (not shown), and the cavity 11 is formed in the flip-up member. The flip-up member can flip relative to the top cover 10 between a horizontal angle and a tilt angle. When the user does not need to view the display screen of the mobile terminal, the flip-up member is rotated to a horizontal angle. At this time, the bottom wall 17 of the cavity is in a horizontal position, so that the functional module 300 is placed horizontally, and thus the mobile terminal located in the charging unit 301 is also placed horizontally. When the user needs to view the display screen of the mobile terminal, the flip-up member is rotated to a tilt angle. At this time, the bottom wall 17 of the cavity is tilted and at a preset angle, so that the mobile terminal located in the charging unit 301 is supported at a preset angle so that the user can view the display screen of the mobile terminal.

[0064] In some embodiments, the top cover 10 has a movable member (not shown) within the chamber 11. The movable member is movable relative to the top cover 10 between a first height and a second height, where the first height is higher than the second height. When the movable member is at the first height, it covers the opening 12 of the chamber; when the movable member is at the second height, it exposes the chamber 11. Simultaneously, the top surface of the movable member forms the bottom wall 17 of the chamber 11. The movable member allows the chamber 11 to cover the opening 12 when not in use, reducing the risk of water ingress into the chamber 11 and also improving the aesthetics of the top cover 10.

[0065] Optionally, the bottom of the movable component is connected to an elastic element, such as a spring. When the functional module 300 needs to be stored, the functional module 300 is placed on the movable component at a first height. The functional module 300 presses down on the movable component and the elastic element by gravity, causing the movable component to descend to a second height and compress the elastic element, thereby storing the functional module 300 in the cavity 11. When the functional module 300 is removed from the cavity 11, the elastic element applies force to the movable component, causing the movable component to rise to the first height to cover the cavity opening 12. Understandably, the elastic element can also be replaced by a driving component such as a motor, and the user controls the driving component to control the lifting and lowering of the movable component.

[0066] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
