Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a mobile power device. Background Technology

[0002] With the rapid development of the mobile phone industry, various application tools, games, and other software are becoming increasingly numerous and innovative, attracting a large user base. Product competition is intensifying, and market demands are becoming more diversified to meet human needs, including a growing demand for longer battery life. To meet different customer needs, companies are constantly innovating products that enhance battery life (such as power banks). To facilitate convenient charging, some power banks have added charging cable functionality. To reduce the failure rate of the charging cable function and lower production and maintenance costs, most power banks with cables on the market currently use a connection between the charging cable and PCB pads.

[0003] However, since the charging cable is soldered separately to the power PCB, users often experience charging cable malfunctions (such as cracking or poor soldering) during use, rendering mobile phones and other products unusable. Repairing the power bank requires disassembling the entire device, resulting in high repair costs and long maintenance cycles.

[0004] Some power banks offer detachable power cord connectors to accommodate different electronic products. However, these connectors are usually plugged directly into the power bank itself and can easily become loose after prolonged use, leading to poor contact. Utility Model Content

[0073] like Figures 1-11 As shown, this embodiment provides a mobile power supply device having a first direction X, a second direction Y, and a third direction Z that intersect each other.

[0074] In some implementations, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0075] In some embodiments, the portable power bank includes a power supply body 10 and a wire connector 20, wherein the wire connector 20 can be plugged into the power supply body 10 along a first direction X. In this way, when the power supply body 10 is functioning well, the wire connector 20 can be quickly replaced separately when it is damaged, reducing rework and extending the service life of the portable power bank. Moreover, the plug-in connection between the power supply body 10 and the wire connector 20 does not require disassembly of the power supply body 10, reducing maintenance costs, shortening maintenance cycles, and improving user convenience.

[0076] In a specific embodiment, the power supply body 10 includes a housing 110. Along a first direction X, the housing 110 has a first window 111 and a first mounting surface 112 facing the first window 111. The first mounting surface 112 has a second window 114 extending along a second direction Y. A wire connector 20 can be inserted into or detached from the first window 111 along the first direction X. The wire connector 20 includes a wire box 210 and a locking mechanism 220. The locking mechanism 220 is disposed inside the wire box 210. The wire box 210 has a second mounting surface 211, which has a third window 212. The locking mechanism 220... A small portion of the locking mechanism 220 can extend outward from the third window 212 along the second direction Y and can also extend into the second window 114 to lock the wire connector 20 and the power supply body 10. Thus, when the power supply body 10 and the wire connector 20 are connected, at least a portion of the locking mechanism 220 can extend into the second window 114. When the wire connector 20 needs to be removed, it can be unlocked by controlling the locking mechanism 220, thereby enabling quick replacement of the wire connector 20, reducing rework, and extending the service life of the power bank. The locking mechanism 220 ensures that the wire connector 20 will not fall off after installation, making it convenient for users to carry and use.

[0077] In some embodiments, the power supply body 10 has a first connection terminal 130 facing the first window 111, and the wire connector 20 has a second connection terminal 230. The second connection terminal 230 is configured to be electrically connected to the first connection terminal 130 when the wire connector 20 is plugged into the power supply body 10. That is, when the wire connector 20 and the power supply body 10 are locked together, the second connection terminal 230 is connected and conductive to the first connection terminal 130. At this time, the power supply device can normally charge the user's mobile phone, tablet or computer.

[0078] In some embodiments, to accommodate the use of multiple devices, the first window 111 can be provided in multiple ways, and the power supply body 10 has multiple first connection terminals 130 corresponding to different first windows 111, so as to satisfy the simultaneous assembly of multiple wire connectors 20 and the electrical connection between the wire connectors 20 and the power supply body 10, thereby providing multiple charging cables for multiple devices to use at the same time.

[0079] In some embodiments, the power bank device further includes a positioning strip 113 and a positioning groove 213; wherein, the positioning strip 113 is disposed on the first mounting surface 112 and extends along the first direction X, and the positioning groove 213 is disposed on the second mounting surface 211 and extends along the first direction X; the positioning strip 113 is configured to slide and engage with the positioning groove 213 when the wire connector 20 is inserted into the first window 111; thereby, when assembling the wire connector 20 and the power body 10, the positioning groove 213 of the wire connector 20 is aligned with the positioning strip 113, and the wire connector 20 is pushed into the first window 111 along the first direction X, thereby achieving precise and rapid docking between the wire connector 20 and the power body 10.

[0080] In some implementations, one end of the positioning groove 213 is Y-shaped, so that when the wire connector 20 is plugged into the power supply body 10, the positioning strip 113 can accurately align with the positioning groove 213, thereby improving installation efficiency.

[0081] In some embodiments, to facilitate the assembly and disassembly of the wire connector 20 and the power supply body 10, the locking mechanism 220 includes a pressing part 221 and a locking part 222. Specifically, the pressing part 221 is disposed in the wire box 210 and is configured to move along a first direction X when pressed. The locking part 222 is disposed in the wire box 210 and is movably connected to the pressing part 221. The locking part 222 is configured to move along a second direction Y under the drive of the pressing part 221, and at least a portion of the locking part 222 can extend out of the outer side of the third window 212. The user can unlock the locking part 222 by pressing the pressing part 221, thereby realizing the assembly and disassembly of the wire connector 20 and the power supply body 10, making replacement faster and easier.

[0082] In some embodiments, the junction box 210 is provided with a third limiting part 217; the pressing part 221 includes a push plate 2211, a limiting post 2214, and a first elastic member 2215; wherein, the push plate 2211 is movably connected to the locking part 222, the limiting post 2214 is connected to the push plate 2211 and extends along a first direction X, the first elastic member 2215 is sleeved on the limiting post 2214 and abuts against the third limiting part 217, and the first elastic member 2215 is configured to drive the push plate 2211. 211 moves away from the third limiting part 217 along the first direction X. Thus, when the user presses the push plate 2211, the first elastic element 2215 is compressed. At the same time, the push plate 2211 can convert the movement in the first direction X into the movement of the locking part 222 in the second direction Y, thereby realizing the retraction of the locking part 222 and realizing the unlocking action. When the external force applied to the push plate 2211 disappears, the push plate 2211 resets under the action of the first elastic element 2215, thereby driving the locking part 222 to reset and extend out of the third window 212, realizing the locking action.

[0083] In some embodiments, to facilitate user operation, the pressing part 221 further includes a button 2213, which is embedded in the junction box 210, and the push plate 2211 is connected to the button 2213. This allows the user to push the push plate 2211 from outside the junction box 210 to move it along the first direction X, thereby retracting the locking part 222 into the inside of the third window 212, unlocking the power supply body 10 and the wire connector 20, and allowing the wire connector 20 to be slid out for replacement. By setting the button 2213, the wire connector 20 can be quickly replaced, shortening the maintenance cycle. Users can also operate it independently without having to return it to the factory for repair, thus reducing maintenance costs.

[0084] In some embodiments, to facilitate the conversion of the movement of the push plate 2211 in the first direction X into the movement of the locking part 222 in the second direction Y, a push rod 2212 is provided on the push plate 2211; the locking part 222 includes a linkage rod 2221, a linkage member 2222, and a locking tongue 2224; wherein, the linkage rod 2221 extends along the second direction Y, the linkage member 2222 is provided at one end of the linkage rod 2221, the linkage member 2222 is provided with a guide groove 2223, specifically, the guide groove 2223 is an inclined groove, the push rod 2212 is provided in the guide groove 2223, and the push rod 2212 is provided in the guide groove 2223. When the push rod 2212 moves along the first direction X, it can drive the linkage 2222 to move along the second direction Y. The locking tongue 2224 is located at the end of the linkage rod 2221 away from the linkage 2222. The locking tongue 2224 can extend or retract into the third window 212 along the second direction Y. Thus, when the push rod 2212 moves along the first direction X, since the guide groove 2223 is an inclined groove, it can synchronously drive the linkage 2222 to move along the second direction Y, thereby enabling the locking tongue 2224 to extend or retract into the third window 212 along the second direction Y, realizing the locking or unlocking action.

[0085] In some embodiments, the latch 2224 is provided with an abutment surface 2225, which is configured to abut against the housing 110 during the insertion of the wire connector 20 into the first window 111 in the first direction X, and to retract the latch 2224 into the third window 212 under the reaction force of the housing 110. Thus, when assembling the wire connector 20 and the power supply body 10, the positioning groove 213 of the wire connector 20 is aligned with the positioning strip 113, and the wire connector 20 is pushed into the first window 111 in the first direction X. The abutment surface 2225 first abuts against the housing 110, and the latch 2224 retracts into the third window 212 under the reaction force of the housing 110.

[0086] In some embodiments, the abutment surface 2225 is a bevel or an arc surface, which pushes the wire connector 20 into the first window 111 along the first direction X, so that the abutment surface 2225 abuts against the housing 110, and the housing 110 can squeeze the locking tongue 2224 to automatically retract into the inner side of the third window 212; the bevel or arc surface design can reduce the insertion resistance between the wire connector 20 and the power supply body 10 and improve the ease of operation.

[0087] In some embodiments, to make the locking tongue 2224 more stable after locking, the power bank device further includes a second limiting part 216, a limiting step 2226, and a second elastic member 2227; wherein, the second limiting part 216 is disposed inside the cable box 210, the limiting step 2226 is disposed between the linkage rod 2221 and the locking tongue 2224, the second elastic member 2227 is sleeved on the linkage rod 2221, and along the second direction Y, the two ends of the second elastic member 2227 abut against the second limiting part 216 and the limiting step 2226 respectively, and the second elastic member 2227 is configured to drive the locking tongue 2224 to extend out of the third window 212 along the second direction Y; when When the contact surface 2225 abuts against the housing 110, it can push the locking tongue 2224 to retract into the inner side of the third window 212, and the second elastic element 2227 is compressed. When the limiting block 214 is inserted into the limiting groove 118, the third window 212 overlaps with the second window 114. The locking tongue 2224 pops out and resets under the action of the second elastic element 2227, thereby locking the wire connector 20 and the power supply body 10. Under the action of the first elastic element 2215 and the second elastic element 2227, the locking tongue 2224 is always in the state of the third window 212 without the action of external force, thereby achieving the locking with the power supply body 10 and preventing the wire connector 20 from falling off and affecting the user experience.

[0088] In some embodiments, the first elastic element 2215 and the second elastic element 2227 are preferably compression springs.

[0089] In some embodiments, the power bank device further includes a first PCB board 120, a second PCB board 250, and a charging cable 240; wherein the first PCB board 120 is disposed on the housing 110, a first connecting terminal 130 is connected to the first PCB board 120, the second PCB board 250 is disposed on the junction box 210, a second connecting terminal 230 is electrically connected to the second PCB board 250, and the second connecting terminal 230 extends at least partially to the outside of the junction box 210, and the charging cable 240 is electrically connected to the second PCB board 250; wherein the second connecting terminal 230 is configured to be electrically connected to the first connecting terminal 130 when the cable connector 20 is plugged into the power body 10, and the second connecting terminal 230 is connected and conductive to the first connecting terminal 130 after the cable connector 20 and the power body 10 are locked, at which time the power bank device can normally charge the user's mobile phone, tablet or computer, etc.

[0090] In some embodiments, to further achieve precise assembly of the wire connector 20 and the power supply body 10, the mobile power device further includes a first limiting part 116 and a limiting block 214. The first limiting part 116 is disposed on the housing 110 and has a protrusion 117. The protrusion 117 forms a limiting groove 118 along the third direction Z toward the inside of the housing 110. The limiting block 214 is attached to the outer wall of the wire box 210. The limiting block 214 is configured to be able to be embedded in the limiting groove 118 along the first direction X when the wire connector 20 is inserted into the power supply body 10. Thus, when the limiting block 214 is engaged in the limiting groove 118, the third window 212 overlaps with the second window 114, and the locking tongue 2224 pops out and resets under the action of the second elastic member 2227, thereby locking the wire connector 20 and the power supply body 10.

[0091] In some embodiments, a battery 140 is also provided inside the housing 110. The battery 140 is electrically connected to the first PCB board 120, thereby enabling it to output power to mobile phones, tablets, or computers.

[0092] In some embodiments, battery 140 is a rechargeable battery, also known as a rechargeable battery or accumulator, which refers to a battery that can be recharged after discharge to reactivate its active materials and continue to be used. Utilizing the reversibility of chemical reactions, a new battery can be constructed; that is, after a chemical reaction converts into electrical energy, the electrical energy can be used to repair the chemical system, and then the chemical reaction can be converted back into electrical energy. Therefore, it is called a rechargeable battery. Common rechargeable batteries on the market include nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid (or lead-acid) batteries, lithium-ion batteries, and polymer lithium-ion batteries. In addition, the casing 110 is also equipped with a charging interface, which is connected to the first PCB board 120 for connecting to an external power source to charge battery 140.

[0093] In some embodiments, to facilitate the storage of the charging cable, the first limiting part 116 is also provided with a cable retaining groove 119 to fix the charging cable 240 and prevent damage to the charging cable 240 during carrying. In addition, the outer wall of the housing 110 is provided with a storage groove 115, which communicates with the cable retaining groove 119. The storage groove 115 can accommodate the connector end of the charging cable 240, thereby protecting the connector end and preventing damage caused by frequent friction during carrying.

[0094] In some embodiments, the charging connector includes, but is not limited to, Micro-USB connectors, Type-A connectors, Type-B connectors, Type-C connectors, and Lightning connectors. It should be noted that those skilled in the art can make various improvements and substitutions without departing from the principles of this invention, and these improvements and substitutions should also be considered within the scope of protection of this invention.

[0095] In some embodiments, there is at least one charging cable 240, and in a preferred embodiment, there are two charging cables 240 to increase the adaptability of the power bank device and meet user needs.

[0096] In some embodiments, to facilitate the installation of the locking mechanism 220 inside the junction box 210, the junction box 210 includes a box body 210a and a cover plate 210b. The box body 210a has an opening, and the cover plate 210b is disposed at the opening. The box body 210a and the cover plate 210b are connected by fasteners 215, thereby forming a closed space inside the junction box 210, which effectively protects the locking mechanism 220. Furthermore, designing the box body 210a and the cover plate 210b to be detachable facilitates the assembly of the locking mechanism 220, as well as the assembly of the second connecting terminal 230, the second PCB board 250, and the charging cable 240, thereby improving assembly efficiency.

[0097] In some implementations, fastener 215 may be a bolt fastener or a snap fastener.

[0098] The working process of this utility model is as follows: Please refer to... Figures 1-11 After the power supply body 10 is inserted into the wire connector 20, the locking tongue 2224 extends into the second window 114 to lock the power supply body 10 and the wire connector 20.

[0099] When the wire connector 20 needs to be removed for replacement, press the button 2213 along the first direction X to push the push plate 2211 to move along the first direction X, which in turn drives the push rod to move along the first direction X. Under the action of the guide groove 2223, the locking tongue 2224 is driven to retract into the wire box 210 along the second direction Y through the linkage 2222, so that the locking tongue 2224 disengages from the second window 114. The wire connector 20 can be pulled out of the first window 111 along the first direction X. During the process of pressing the button 2213, the first elastic element 2215 and the second elastic element 2227 are further compressed. After releasing the button 2213, the push plate 2211 resets along the first direction X under the action of the first elastic element 2215, so that the button 2213 pops out and resets. The locking tongue 2224 pops out of the third window 212 under the action of the second elastic element 2227.

[0100] When assembling the wire connector 20 and the power supply body 10, align the positioning groove 213 of the wire connector 20 with the positioning strip 113, and push the wire connector 20 into the first window 111 along the first direction X. The abutment surface 2225 first abuts against the housing 110. Since the abutment surface 2225 is a slope or arc surface, when the abutment surface 2225 abuts against the housing 110, it can push the locking tongue 2224 to retract into the inner side of the third window 212. The second elastic element 2227 is compressed. When the limiting block 214 is inserted into the limiting groove 118, the third window 212 overlaps with the second window 114. The locking tongue 2224 pops out and resets under the action of the second elastic element 2227, thereby locking the wire connector 20 and the power supply body 10.

[0101] After the wire connector 20 and the power supply body 10 are locked, the second connection terminal 230 is connected and conducts through the first connection terminal 130.

[0102] In summary, this utility model provides a mobile power supply device whose wire connector 20 can be plugged into the power supply body 10 along the first direction X. When the power supply body 10 is functioning well, the wire connector 20 can be quickly replaced separately when damaged, reducing rework and extending the service life of the mobile power supply device. Furthermore, the plug-in connection between the power supply body 10 and the wire connector 20 eliminates the need to disassemble the power supply body 10, reducing maintenance costs, shortening the maintenance cycle, and improving user convenience.
