[0037] See also Figure 1-Figure 3 The present embodiment provides a mobile power source with a detachable battery, including a battery compartment 1 and a charging module 2. A receiving groove 11 with an opening at one end is formed in the battery compartment 1, and a battery 3 is arranged in the receiving groove 11. The charging module 2 is arranged on one side of the opening of the battery compartment 1, and the battery compartment 1 and the charging module 2 are detachably electrically connected.

[0038] Since the battery compartment 1 and the charging module 2 are detachably connected, and the charging module 2 is arranged on one side of the opening of the battery compartment 1, when the connection between the battery compartment 1 and the charging module 2 is released, the battery 3 in the battery compartment 1 can be taken out.

[0039] After a traditional mobile power source is used for a long time, the battery will age or the capacity will be insufficient, and the entire mobile power source needs to be replaced. However, the mobile power source provided by this embodiment is equivalent to a new mobile power source by replacing the battery, and the cost is greatly reduced.

[0040] Since the batteries of the mobile power supply provided in this embodiment are replaceable, if a long-distance trip is required, the user only needs to carry the mobile power supply and a sufficient number of replaceable batteries.

[0041] The battery 3 is usually a lithium battery. With the continuous research and development of lithium batteries, better and newer lithium batteries can be applied to the mobile power supply provided in this embodiment.

[0042] In one embodiment, the control board of the mobile power supply is arranged in the charging module 2 .

[0043] When the battery compartment 1 and the charging module 2 are connected, the battery 3 in the battery compartment 1 can supply power to the control board in the charging module 2 .

[0044] For example, if the mobile phone charging protocol is upgraded, the old mobile power supply is not suitable for the new protocol and needs to be completely replaced. However, the mobile power supply provided in this embodiment only needs to replace the charging module 2, and does not need to replace the battery compartment 1 and the battery 3, which greatly reduces the cost.

[0045] In the case where the control board of the mobile power supply is arranged in the charging module 2, in one embodiment, see Figure 1 A charging socket 22 is provided on the side of the charging module 2 facing away from the battery compartment 1 , and a button 23 and an indicator light 24 are provided on the circumferential side of the charging module 2 .

[0046] The button 23 can be used for power-on function, the indicator light 24 can be used to indicate the power status, and the charging socket 22 can be connected to a terminal such as a mobile phone through a data cable to charge the terminal such as the mobile phone.

[0047] See also Figure 1 , indicating that the indicator light 24 is arranged below the button 23. By arranging the button 23 and the indicator light 24 on the same side of the charging module 2, it is convenient to press the button 23 to turn on the power and observe the indicator light 24, so as to timely understand the power status of the mobile power supply.

[0048] In one embodiment, the charging module 2 is disposed on one side of the battery compartment 1 along the length direction, and the length of the battery compartment 1 is greater than the length of the charging module 2 in the same direction.

[0049] See also Figure 1-Figure 3 , illustrating the positional relationship and size of the charging module 2 and the battery compartment 1.

[0050] The charging module 2 provided in this embodiment is conducive to designing the shape of the mobile power supply to be compact and easy to carry.

[0051] In one embodiment, the mobile power source is cylindrical or rectangular.

[0052] See also Figure 1 , illustrating a rectangular power bank with rounded edges, which facilitates the carrying of the power bank.

[0053] Regarding the size of the mobile power bank, for example, the height of the mobile power bank can be set to about 90mm, see Figure 1 ,by Figure 1 The middle vertical direction is the height direction of the mobile power supply, and the length and width of the mobile power supply can be designed to be about 34 mm and about 30 mm respectively.

[0054] Regarding the detachable electrical connection between the battery compartment 1 and the charging module 2, in one embodiment, a metal rod 21 is provided on the side of the charging module 2 close to the battery compartment 1, and the number of the metal rods 21 may be two. A slot 12 is provided at one end of the opening of the battery compartment 1, and each metal rod 21 corresponds to a slot 12.

[0055] See also Figure 2 and Figure 3 , schematically shows the metal rod 21 on the charging module 2 and the slot 12 on the opening side of the battery compartment 1. When the metal rod 21 and the slot 12 are inserted into place, the electrical connection between the battery compartment 1 and the charging module 2 can be achieved.

[0056] In one embodiment, the mobile power supply includes a locking structure, and the slot 12 extends along the circumferential direction of the battery compartment 1. When the metal rod 21 is inserted into the slot 12 and the metal rod 21 is rotated along the direction of the slot 12 to the connected position, the metal rod 21 can be locked on the battery compartment 1 through the locking structure.

[0057] When using the mobile power supply provided by this embodiment, first align the metal plug 21 on the charging module 2 with the corresponding slot 12, then insert the metal plug 21 into the slot 12, and when the metal plug 21 is inserted to a depth that cannot be inserted any further, rotate the charging module 2, and when it is rotated to the right position (i.e., the charging module 2 cannot be rotated any further), operate the locking structure to lock the metal plug 21 on the battery compartment 1, thereby locking the charging module 2 on the battery compartment 1. When it is necessary to remove the charging module 2 from the battery compartment 1, operate the locking structure to release the lock on the metal plug 21, and then rotate the charging module 2 in the opposite direction, and when it is rotated to the right position, pull the charging module 2 out of the battery compartment 1.

[0058] In this embodiment, the charging module 2 can be locked on the battery compartment 1 by providing a locking structure, so that when the charging module 2 is connected to the battery compartment 1, the charging module 2 is prevented from being detached from the battery compartment 1.

[0059] Regarding the specific shape of the slot 12, in one embodiment, the metal insert rod 21 includes a main body 211 and a spherical end 212, the spherical end 212 is arranged at the free end of the main body 211, and the area of ​​the cross section of the spherical end 212 passing through the center of the ball is larger than the cross-sectional area of ​​the main body 211; the slot 12 is formed with a longitudinal flaring portion 121 on one side along the circumferential direction of the battery compartment 1, the longitudinal flaring portion 121 allows the spherical end 212 to be inserted, and a transverse flaring portion 122 is formed at the bottom of the slot 12, the transverse flaring portion 122 allows the spherical end 212 to rotate.

[0060] See also Figure 2 , schematically shows the main body 211 and the spherical end 212 of the metal plug 21 , the main body 211 is cylindrical, and the cross-sectional area of ​​the spherical end 212 passing through the center of the sphere is larger than the cross-sectional area of ​​the main body 211 .

[0061] See also Figure 4 and Figure 6 , schematically showing the longitudinal flared portion 121 and the transverse flared portion 122, the shape of the longitudinal flared portion 121 matches the spherical end portion 212, so that the metal plug 21 can be inserted through the longitudinal flared portion 121. The shape of the transverse flared portion 122 matches the spherical end portion 212, so that the metal plug 21 can rotate. Figure 4 and Figure 6 , for the slot 12, the portion located on the right side of the longitudinal flared portion 121 and above the transverse flared portion 122 (called the waist-shaped portion 123) matches the shape of the main body 211. A step is formed between the transverse flared portion 122 and the waist-shaped portion 123. When the metal plug 21 is located in the slot 12 and at the end away from the longitudinal flared portion 121, the charging module 2 cannot be pulled out in the direction away from the battery compartment 1 because the size of the waist-shaped portion 123 in the radial direction of the battery compartment 1 is smaller than the diameter of the spherical end 212.

[0062] In one embodiment, the locking structure includes an elastic member and a limiting structure 4. A metal strip is provided on the bottom surface of the longitudinal flared portion 121. An elastic member is provided at the bottom of the metal strip near one end of the longitudinal flared portion 121 to facilitate propping up one end of the metal strip. The limiting structure 4 is slidably connected to the battery compartment 1. When the metal plug 21 is in the connected position, the sliding limiting structure 4 can limit the elastic member from being squeezed so that the metal plug 21 is locked on the battery compartment 1.

[0063] See also Figure 4 and Figure 6 A metal sheet 5 is arranged in the transverse flared portion 122 , and the length direction of the metal sheet 5 is along the length direction of the transverse flared portion 122 . The metal sheet 5 is connected to the metal plug rod 21 , thereby realizing the electrical connection between the charging module 2 and the battery compartment 1 .

[0064] The end of the metal sheet 5 located at the longitudinal expansion portion is called the first end, an elastic member is arranged below the first end (the elastic member is not shown in the figure), and the end of the metal sheet 5 away from the longitudinal expansion portion is called the second end, which is fixed to the battery compartment 1. Under the elastic force of the elastic member, the first end of the metal sheet 5 is tilted upward. The elastic member can be a spring.

[0065] When using the mobile power supply provided by this embodiment, first align the metal plug 21 on the charging module 2 with the corresponding longitudinal flared portion 121, and then insert the metal plug 21 into the slot 12. When the insertion depth of the metal plug 21 reaches the point where it cannot be inserted any further (the elastic member is in a compressed state at this time, and the first end of the metal sheet 5 is pressed downward), rotate the charging module 2. When it is rotated to the right position (i.e., the charging module 2 cannot continue to rotate), the spherical end 212 of the metal plug 21 is connected to the second end of the metal sheet 5, and the first end of the metal plug 21 is tilted upward under the action of the elastic member. At this time, the spherical end 212 of the metal plug 21 abuts against the transverse flared portion 122 and the waist-shaped portion 123 to form a step. At this time, the locking structure is operated to limit the elastic member from being squeezed, and the charging module 2 cannot rotate in the opposite direction and is locked on the battery compartment 1. When the locking structure is operated so that it does not restrict the elastic member, the charging module 2 rotates in the opposite direction, gradually squeezing the elastic member during the rotation process, so that the metal plug 21 rotates to the longitudinal expansion portion 121, and then the charging module 2 is pulled out from the battery compartment 1.

[0066] Regarding the specific structure of the limiting structure 4, in one embodiment, the limiting structure 4 includes a sliding key 41, a limiting block 42 and a connecting portion 43. The sliding key 41 is arranged on the outer surface of the battery compartment 1. The sliding key 41 is connected to the limiting block 42 through the connecting portion 43. The limiting block 42 is used to prevent the elastic member from being squeezed downward.

[0067] See also Figure 4 A limiting block 42 is provided on a side close to the first end of the metal sheet 5. When the limiting block 42 slides to below the first end of the metal sheet 5, the first end of the metal sheet 5 cannot be pressed downward, that is, the elastic member cannot be compressed; when the limiting block 42 slides to below away from the first end of the metal sheet 5, the first end of the metal sheet 5 can be pressed downward, that is, the elastic member can be compressed.

[0068] The limiting structure 4 includes a sliding push button 41, see Figure 1 , schematically shows a push button 41, which is connected to the fiber block via a connecting portion 43. Figure 1 When the sliding key 41 is slid from the right end to the left end, the limit block 42 is located below the first end of the metal sheet 5 (or the limit block 42 is away from the first end of the metal sheet 5); when the sliding key 41 is slid from the left end to the right end, the limit block 42 is away from the first end of the metal sheet 5 (or the limit block 42 is located below the first end of the metal sheet 5).

[0069] Preferably, the letters “LOCK” and “UNLOCK” may be marked on the battery compartment 1 to remind the user to operate the slide button 41 .

[0070] The number of the limiting block 42 can be set to one, and used in conjunction with one metal sheet 5. Because when a metal plug 21 is locked on the battery compartment 1, the charging module 2 cannot be pulled out from the battery compartment 1.

[0071] Of course, the number of the limit blocks 42 can be two, and the two limit blocks 42 are respectively matched with the corresponding metal sheets 5. Figure 7 , an embodiment of the time-limiting structure 4 is given when the limiting blocks 42 are two.

[0072] The limiting structure 4 can be set as an integrated structure, and the material can be plastic.

[0073] In addition, a matching groove is provided in the battery compartment 1 to facilitate the installation of the limiting structure 4 , and the shape of the matching groove needs to match the shape of the limiting structure 4 .

[0074] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
