Detailed Implementation

[0020] To better understand the purpose, structure, and function of this invention, a mobile power supply of this invention will be described in further detail below with reference to the accompanying drawings.

[0021] Example 1 like Figure 1 As shown, a portable power supply according to the present invention includes a battery module 1, a combination module A and a combination module B. Combination modules A and B are movably disposed on both sides of the battery module 1 through a snap-fit ​​mechanism, and the battery module 1 directly supplies power to combination modules A and B.

[0022] Specifically, the battery module 1 is provided with several first slots 01 and second slots 02, wherein the first slots 01 are connected to the combination module A, and the second slots 02 are connected to the combination module B. In the specific connection, multiple combination modules A are connected to one side of the battery module 1, and the other side can be replaced with combination modules B with different functions as needed.

[0023] In the specific implementation process, the combination module A is provided with a first boss 011 that cooperates with the first slot 01. The first boss 011 is provided with a bracket 013. The first boss 011 is provided with buckles 012 on both sides. The buckles 012 are provided with positioning holes 0123 and reset holes 0124, which are respectively connected to positioning posts 0126 and reset posts 0125 provided on the combination module A. The buckles 012 are also provided with a limiting head 0122 and a first locking tongue 0121. The first locking tongue 0121 cooperates with the locking openings 01211 on both sides of the first slot 01.

[0024] When using, such as Figures 9-11 , Figure 25 and Figure 26 As shown, a spring can be fitted onto the reset post 0125, with the other end of the spring positioned in the reset hole 0124, to achieve automatic reset of the latch 012. During installation, align the first protrusion 011 on the combination module A with the first slot 01. Pressing down causes the edge of the first slot 01 to press against the first locking tongue 0121, causing the latch 012 to retract onto the combination module A, thus engaging the first locking tongue 0121 with the lock opening 01211 and securing the combination module A. To remove, simply press the latches 012 on both sides of the combination module A to separate the first locking tongue 0121 from the lock opening 01211.

[0025] In this application, the assembly module A has two first protrusions 011, and a bracket 013 is provided between the two first protrusions 011. The bracket 013 has ring teeth 0131, which are gear-shaped. The assembly module A has a rotating shaft 182 for mounting the bracket 013, and a limiting part 181 that cooperates with the ring teeth 0131. The rotating shaft 182 is located between the first protrusions 011. The limiting part 181 is a protrusion provided on the assembly module A. The opening and closing angle of the bracket 013 is limited by the engagement of the protrusion with the teeth on the ring teeth 0131.

[0026] The first protrusion 011 has a recess, and a micro switch 014 is installed in the recess. The first slot 01 has a protrusion that mates with the recess. After the combined module A and the battery module 1 are combined, the protrusion presses against the micro switch 014.

[0027] When in use, by forcefully bending the bracket 013, the protruding limiting part 181 passes through the teeth on the ring tooth 0131, thereby adjusting the position of the bracket 013.

[0028] The bracket 013 has several holes 0132, which make it easy to hang the speaker body 1.

[0029] A handle 0133 is provided at the end of the bracket 013. This handle 0133 is provided at the end of the bracket 013. On the one hand, it is convenient to lift the combined module A. On the other hand, when the bracket 013 is placed as a support leg, the handle 0133 can provide a wider contact surface, making the placement more stable.

[0030] In the specific implementation process, the combination module B is provided with a second boss 026 that cooperates with the second slot 02. The second boss 026 is provided with a protruding limiting part 027 and a recessed part 23. Several protruding gap elimination parts 261 are provided on the side of the second boss 026. A second locking tongue 022 is provided below the combination module B. The middle part of the second locking tongue 022 is set at the bottom of the combination module B through a rotating shaft 24. One end of the second locking tongue 022 is provided with a protruding locking head that is locked in the second slot 12. The other end of the second locking tongue 022 is connected to the combination module B through a spring 25. A first locking head 021 is provided above the second boss 026.

[0031] On the battery module 1 connected to the combination module B, the second slot 02 has a top slot 029 above it that cooperates with the first slot head 021, a bottom slot 028 below it that cooperates with the second locking tongue 022, a positioning recess 0271 above it that cooperates with the protruding limiting part 027, and a protruding head 0231 that cooperates with the recess 023.

[0032] In use, first insert the first locking head 021 into the top locking slot 029, and then insert the second locking tongue 022 into the bottom locking slot 028. Under the action of the spring 025, the second locking tongue 022 remains connected to the bottom locking slot 028, thus connecting the assembly module B and the battery module 1 together. The cooperation between the recessed portion 023 and the protruding limiting portion 027 prevents relative sliding between the assembly module B and the battery module 1 on the contact surface.

[0033] The cooperation between the second protrusion 026 and the second slot 02 further avoids instability in edge contact between the combined module B and the battery module 1, and improves the stability of the connection.

[0034] The second protrusion 026 has several gap elimination parts 0261 along its edge. The gap elimination parts 0261 can reduce the assembly gap between the combined module B and the battery module 1, and prevent shaking.

[0035] The cooperation between the protruding limiting part 027 and the positioning recess 0271 can further improve stability and eliminate the leakage after installation.

[0036] When separating the two components, simply press the tail of the second locking tongue 022 to compress the spring 025, which will cause the second locking tongue 022 to lift up and separate from the bottom slot 028. Then, lift the bottom of the combined module B to remove it.
