[0035] With reference to Figures 1 to 8 An embodiment of the utility model discloses a mobile power supply, including casing 100, adapter 200 and storage box 300. Casing 100 is internally provided with battery assembly, and casing 100 is also provided with the first charging wire 110 electrically connected with battery assembly, and the first charging wire 110 extends to the outside of casing 100 and is fixedly connected with the first charging connector 111. Adapter 200 is detachably installed on the first charging connector 111. Storage box 300 is connected to casing 100, and storage box 300 is provided with containing groove 310 for containing adapter 200, and adapter 200 can be taken out from containing groove 310 under external force, or adapter 200 can be stored in containing groove 310 under external force. Wherein, containing groove 310 is provided with clamping assembly, when adapter 200 is inserted in containing groove 310, clamping assembly can clamp adapter 200 and prevent adapter 200 from moving outward relative to containing groove 310.

[0036] By adopting the mobile power supply of the utility model embodiment, the mobile power supply is provided with adapter 200 detachably connected with the first charging connector 111, so that the mobile power supply can be adapted to different types of charging interfaces. By setting storage box 300 and clamping assembly in the containing groove of storage box 300, when adapter 200 is not needed, adapter 200 can be inserted in containing groove 310, and at this time, clamping assembly can clamp and fix adapter 200, prevent adapter 200 from moving outward relative to containing groove 310, so that the risk that adapter 200 falls out of containing groove 310 due to the shaking or vibration of mobile power supply can be reduced, and the risk that adapter 200 is lost can be reduced, ensuring the normal use of mobile power supply. When adapter 200 is needed, adapter 200 can be taken out from containing groove 310 and installed on the first charging connector 111, which is simple in operation and convenient for users to use.

[0037] With reference to Figures 1 to 3 In some embodiments, adapter 200 is provided with connecting piece 220, connecting piece 220 is connected to the first charging wire 110, and adapter 200 can reciprocate between storage box 300 and the first charging connector 111 through connecting piece 220.

[0038] By adopting the above distinguishing technical features, the adapter 200 is mounted on the first charging wire 110 through the connecting piece 220, so that the adapter 200 is connected to the first charging wire 110 whether in use or not, thereby limiting the movement range of the adapter 200 and further preventing the adapter 200 from being lost.

[0039] In some embodiments, the connecting piece 220 is specifically a flexible structure, so that the connecting piece 220 is easy to deform, thereby facilitating the flexible movement of the adapter 200 between the storage box 300 and the first charging head 111. When the adapter 200 is not needed, the adapter 200 can be inserted into the accommodation groove 310 in a direction close to the storage box 300, and when the adapter 200 is needed, the adapter 200 can be mounted on the first charging head 111 in a direction close to the charging head, thereby making the storage and use of the adapter 200 more convenient. The connecting piece 220 can specifically adopt a flexible structure such as a rubber or silica gel structure that is easy to bend and deform, or can adopt a connecting wire structure, thereby facilitating the movement of the adapter 200 in any direction.

[0040] Reference Figures 1 to 3 In some embodiments, the storage box 300 is arranged on the first charging wire 110 and connected to the shell 100 through the first charging wire 110, and the connecting piece 220 is located between the storage box 300 and the first charging head 111.

[0041] By adopting the above structure, the storage box 300 is also arranged on the first charging wire 110, so that the adapter 200 can be directly stored on the first charging wire 110, thereby making the storage and use of the adapter 200 not affected by the relative position between the shell 100 and the first charging head, and further making the storage and use of the adapter 200 more convenient and fast. In addition, by arranging the connecting piece 220 between the storage box 300 and the first charging head 111, the adapter 200 can be conveniently stored in the storage box 300 or mounted on the first charging head 111.

[0042] It can be understood that when the connecting piece 220 adopts a flexible structure, arranging the connecting piece 220 between the storage box 300 and the first charging head 111 can also reduce the deformation amount of the connecting piece 220 when the adapter 200 moves between the storage box 300 and the first charging head 111, thereby slowing down the fatigue damage of the connecting piece 220 during use and prolonging the service life of the connecting piece 220.

[0043] It can be understood that the storage box 300 is arranged on the first charging wire 110, specifically, the storage box 300 and the first charging wire 110 can be arranged as an integrated structure, thereby not only facilitating the production and processing of the storage box 300 and the first charging wire 110, but also making the connection between the storage box 300 and the first charging wire 110 more firm and stable. Of course, in addition thereto, the storage box 300 can also be directly sleeved on the outer periphery of the first charging wire 110, or the storage box 300 and the first charging wire 110 can also be connected through a clamping structure, a welding structure or the like, which is not limited in the utility model.

[0044] It can be understood that the storage box 300 can be arranged on the first charging wire 110 and connected with the shell 100 through the first charging wire 110, and in some embodiments, the storage box 300 can also be directly arranged on the shell 100, specifically, the storage box 300 can be embedded in the shell 100 or directly arranged on the surface of the shell 100, at this time, the storage box 300 can be integrally formed on the shell 100, or the storage box 300 can be directly connected on the shell 100 through a clamping structure, a welding structure or the like, which is not limited in the utility model.

[0045] Referring to Figures 1 to 3 In some embodiments, the connecting piece 220 is movably sleeved on the first charging wire 110 and can reciprocate along the first charging wire 110 between the storage box 300 and the first charging connector 111.

[0046] By adopting the above structure, the connecting piece 220 is movably sleeved on the first charging wire 110, so that the connecting piece 220 can reciprocate along the first charging wire 110 between the storage box 300 and the first charging connector 111, thereby making the movement of the adapter 200 more flexible, and further making the storage and use of the adapter 200 more convenient and fast.

[0047] Referring to Figures 1 to 7 In some embodiments, the clamping assembly includes two groups of elastic mechanisms 400, and all the elastic mechanisms 400 are arranged along the circumference of the accommodating groove 310. The elastic mechanism 400 includes an elastic piece 410 and a pressing piece 420, the elastic piece 410 is arranged on the side wall of the accommodating groove 310, and the pressing piece 420 is arranged at the inner end of the elastic piece 410 and at least partially protrudes into the accommodating groove 310. The adapter 200 can drive the elastic piece 410 to contract and move in and out of the accommodating groove 310 through the pressing piece 420, when the adapter 200 is inserted into the accommodating groove 310, all the pressing pieces 420 can clamp the adapter 200 and prevent the adapter 200 from moving outward relative to the accommodating groove 310.

[0048] By adopting the above structure, the clamping assembly is provided as two sets of elastic mechanisms 400, and the two sets of elastic mechanisms are arranged along the circumference of the accommodating groove 310, so that the adapter 200 can be stably clamped. By providing the elastic mechanism 400 as an elastic piece 410 and a pressing piece 420, the elastic piece 410 is arranged on the side wall of the accommodating groove 310, and the pressing piece 420 is arranged at the inner end of the elastic piece 410, wherein the inner end of the elastic piece 410 refers to the end of the elastic piece 410 towards the inside of the accommodating groove 310. By at least partially protruding the pressing piece 420 in the accommodating groove 310, the adapter 200 can extrude the pressing piece 420 during movement in and out of the accommodating groove 310, and drive the elastic piece 410 to contract through the pressing piece 420. When the adapter is inserted into the accommodating groove 310, each pressing piece 420 can be clamped and fixed to the adapter under the elastic action of the corresponding elastic piece 410, and the adapter is prevented from moving outward relative to the accommodating groove 310, so that the adapter 200 can be stably received in the accommodating groove 310 of the receiving box 300 and is not easy to fall out, thereby reducing the risk of the adapter 200 falling out of the accommodating groove 310 due to shaking or vibration of the mobile power supply, and further reducing the risk of the adapter 200 being lost, ensuring normal use of the mobile power supply.

[0049] It can be understood that, with reference to Figures 1 to 4 In some embodiments, the clamping assembly includes two sets of elastic mechanisms 400, wherein the two sets of elastic mechanisms 400 can be arranged oppositely, so that the adapter 200 is more balanced when moving in and out of the accommodating groove 310, and the movement of the adapter 200 is more balanced and stable.

[0050] It can be understood that the above clamping assembly includes two sets of elastic mechanisms 400, which is only an example of Figures 1 to 7 The number of elastic mechanisms 400 can be three, four or more groups, and the present application does not make specific limitations. In addition, when the number of elastic mechanisms 400 is three or more, all elastic mechanisms 400 can be uniformly arranged along the circumference of the accommodating groove 310, so that the adapter 200 is more balanced when moving in and out of the accommodating groove 310, and the movement of the adapter 200 is more balanced and stable.

[0051] It can be understood that the elastic mechanism 400 includes the elastic piece 410 and the abutting piece 420, the abutting piece 420 is arranged at the inner end of the elastic piece 410, wherein the abutting piece 420 can be arranged in an integral structure with the elastic piece 410, at this time, the inner end of the elastic piece 410 is the abutting piece 420, or the abutting piece 420 can also be arranged in a split structure with the elastic piece 410, at this time, the abutting piece 420 can be connected or abutted to the inner end of the elastic piece 410, and the specific connection relationship between the elastic piece 410 and the abutting piece 420 is not limited in the utility model.

[0052] It can be understood that the elastic piece 410 can specifically adopt a compression spring. Of course, in addition thereto, the elastic piece 410 can also adopt a structure with elasticity such as a rubber piece, a silica gel piece, and the like, and the utility model does not make a specific limitation thereon.

[0053] It can be understood that the clamping assembly can include at least two groups of elastic mechanisms 400, and in some embodiments, the clamping assembly can also include only one group of elastic mechanisms 400, when the adapter 200 is inserted into the accommodating groove 310, the elastic mechanism 400 can abut against the outer wall of the adapter 200 and push the adapter 200 to abut against the inner wall of the accommodating groove 310 opposite to the elastic structure, that is, the elastic structure can cooperate with the inner wall of the accommodating groove 310 to clamp the adapter 200 and prevent the adapter 200 from moving outward relative to the accommodating groove 310. Alternatively, the clamping assembly can be arranged as an annular elastic structure around the peripheral wall of the accommodating groove 310, when the adapter 200 is inserted, the adapter 200 can extrude the annular elastic structure, thereby enabling the adapter 200 to smoothly move in and out of the accommodating groove 310, when the adapter 200 is inserted into the accommodating groove 310, the annular elastic structure can clamp and fix the adapter 200, so that the adapter 200 is stably accommodated in the accommodating groove 310 of the storage box 300 and is not easy to fall out, thereby reducing the risk of loss of the adapter 200.

[0054] Referring to Figures 1 to 8 In some embodiments, the outer wall of the adapter 200 is provided with a positioning groove 210 corresponding to the abutting piece 420, when the adapter 200 is inserted into the accommodating groove 310, the abutting piece 420 can be embedded into the corresponding positioning groove 210.

[0055] By adopting the above structure, the positioning groove 210 corresponding to the pressing piece 420 is arranged on the outer wall of the adapter 200. During the process of inserting the adapter 200 into the accommodating groove 310, the outer wall of the adapter 200 first contacts and extrudes the pressing piece 420, at this time, the elastic piece 410 is contracted, and the adapter 200 can move towards the inside of the accommodating groove 310. When the adapter 200 moves to the position corresponding to the positioning groove 210 and the pressing piece 420, the elastic piece 410 can push the pressing piece 420 to move towards the positioning groove 210 and make the pressing piece 420 embedded in the positioning groove 210, thereby being able to prevent the adapter from moving outward relative to the accommodating groove 310, and limiting the adapter 200 in the accommodating groove 310. When the adapter 200 needs to be used and taken out from the accommodating groove 310, the adapter can move outward under the action of external force to overcome the elastic force of the elastic piece 410, so that the pressing piece 420 can be separated from the positioning groove 210 and compressed under the extrusion of the outer wall of the adapter 200, thereby making the adapter 200 move out of the accommodating groove 310 smoothly.

[0056] It can be understood that, with reference to Figures 1 to 7 , in order that the pressing piece 420 can be embedded in the mounting groove 432 smoothly when the adapter 200 is inserted, and the pressing piece 420 can be separated from the mounting groove 432 smoothly when the adapter 200 is taken out, a guide surface (not marked in the figure) can be arranged on the end of the pressing piece 420 close to the inside of the accommodating groove 310, thereby, when the adapter 200 is inserted, the guide surface can guide the pressing piece 420 to be embedded in the mounting groove 432 smoothly, and when the adapter 200 is taken out, the guide surface can guide the pressing piece 420 to be separated from the mounting groove 432 smoothly, thereby making the insertion and taking out of the adapter 200 more convenient and labor-saving, and convenient for users to use.

[0057] With reference to Figures 1 to 7 , in some embodiments, the side wall of the accommodating groove 310 is provided with the mounting hole 320 corresponding to the elastic mechanism 400, the mounting hole 320 is in communication with the accommodating groove 310, the elastic piece 410 is installed in the mounting hole 320 and connected or abuts against the inner wall of the mounting hole 320, the pressing piece 420 is installed at the end of the elastic piece 410 close to the accommodating groove 310, and the pressing piece 420 can be moved to be contracted in the mounting hole 320 under the extrusion of the adapter 200, or the pressing piece 420 can be moved to protrude from the accommodating groove 310 under the elastic force of the elastic piece 410.

[0058] By adopting the above structure, the installation hole 320 can provide installation space for the elastic mechanism 400. When the adapter 200 is inserted and removed, the adapter 200 can press the pressing piece 420 and move the pressing piece 420 to be retracted in the installation hole 320, so that the adapter 200 can be smoothly moved in and out of the accommodating groove 310. When the adapter 200 moves into the accommodating groove 310 to the positioning groove 210 opposite to the pressing piece 420, the pressing piece 420 can be moved to protrude from the accommodating groove 310 and be embedded in the positioning groove 210 under the elastic action of the elastic piece 410. Thus, the adapter 200 can be prevented from moving outward relative to the accommodating groove 310, and the adapter 200 is limited in the accommodating groove 310, so that the adapter 200 is stably accommodated in the accommodating groove 310 and is not easy to fall out. Thus, the risk of losing the adapter 200 can be reduced, and the normal use of the mobile power supply is ensured.

[0059] With reference to Figures 1 to 7 In some embodiments, the elastic mechanism 400 further includes a limiting piece 430 movably installed in the installation hole 320. The elastic piece 410 is located between the inner wall of the installation hole 320 and the limiting piece 430, and the pressing piece 420 is installed on the side of the limiting piece 430 away from the elastic piece 410. The inner wall of the installation hole 320 is provided with an abutting portion 321 located on the side of the limiting piece 430 away from the elastic piece 410. The abutting portion 321 can abut against the limiting piece 430 and prevent the limiting piece 430 from moving toward the accommodating groove 310.

[0060] By adopting the above structure, when the adapter 200 is inserted and removed, the adapter 200 can press the pressing piece 420 and push the limiting piece 430 to move along the installation hole 320 to compress the elastic piece 410, so that the pressing piece 420 can be moved to be retracted in the installation hole 320. Thus, the adapter 200 can be conveniently moved in and out of the accommodating groove 310. When the adapter 200 moves into the accommodating groove 310 to the positioning groove 210 opposite to the pressing piece 420, the limiting piece 430 can move close to the accommodating groove 310 under the elastic action of the elastic piece 410, so that the pressing piece 420 moves to protrude from the accommodating groove 310 and is embedded in the positioning groove 210. Thus, the adapter 200 can be limited in the accommodating groove 310. In this process, the abutting portion 321 provided on the inner wall of the installation hole 320 can abut against the limiting piece 430 and prevent the limiting piece 430 from continuing to move toward the accommodating groove 310. Thus, the elastic piece 410 and the limiting piece 430 can be limited in the installation hole 320, so that the elastic piece 410 is not directly separated from the installation hole 320 under its own elastic action when it is reset from the retracted state. Thus, the installation of the elastic piece 410 is more stable, and the structure of the elastic mechanism 400 is more stable and compact.

[0061] It can be understood that the elastic member 410 is located between the inner wall of the mounting hole 320 and the limiting member 430, specifically, the limiting member 430 is provided with a protruding positioning portion 431 on the side close to the elastic member 410, and the elastic member 410 is sleeved on the outer periphery of the positioning portion 431, so that the elastic member 410 can be positioned and installed, and the position deviation of the elastic member 410 under pressure can be avoided.

[0062] It can be understood that the abutting member 420 is installed on the side of the limiting member 430 away from the elastic member 410, specifically, Figures 4 to 7 , the limiting member 430 is provided with a mounting groove 432 on the side away from the elastic member 410, and the abutting member 420 is embedded in the mounting groove 432. Among them, the abutting member 420 can be interference fit with the inner wall of the mounting groove 432, so that the installation of the abutting member 420 is more firm and stable. Of course, in addition to the above installation structure, the abutting member 420 can also be directly integrated with the limiting member 430, or the abutting member 420 can also be installed on the limiting member 430 through a welding structure, a clamping structure or the like, which is not limited by the utility model.

[0063] Referring to Figures 4 to 7 , in some embodiments, the mounting hole 320 is a through hole penetrating through the side wall of the storage box 300, and the outer end of the mounting hole 320 is provided with a baffle 330, one end of the elastic member 410 abuts against the baffle 330, and the other end is connected or abuts against the limiting member 430.
