[0036] This embodiment discloses a mobile power source. Figure 1-7 , comprising a power supply housing 1 and a battery assembly 2, wherein the power supply housing 1 comprises a first housing 3 and a second housing 4;

[0037] First mounting plates 301 are respectively provided on opposite sides of the first housing 3, and the battery assembly 2 is arranged between the first mounting plates 301 on opposite sides; a first buckle 302 is provided in the middle of the first mounting plate 301, and a buckle gap 303 is provided between the side of the first mounting plate 301 facing away from the battery assembly 2 and the side wall of the first housing 3;

[0038] Second mounting plates 401 are respectively provided on opposite sides of the interior of the second shell 4, and a second fastener 402 is provided in the middle of the second mounting plate 401; when the first shell 3 and the second shell 4 are connected to each other, the second mounting plate 401 is inserted into the fastener gap 303, and the first fastener 302 and the second fastener 402 are engaged with each other; at the same time, the second mounting plate 401 applies a force to the first mounting plate 301 in the direction of the battery assembly 2, so that the first mounting plates 301 on the opposite sides cooperate with each other to clamp and fix the battery assembly 2.

[0039] In the installation process of the battery assembly 2 and the power supply housing 1 of the utility model, the battery assembly 2 is first placed between the first mounting plates 301 on the opposite sides of the first housing 3; then the second housing 4 is connected to the first housing 3; specifically, the second mounting plate 401 of the second housing 4 is inserted into the snap gap 303, so that the first snap member 302 and the second snap member 402 are mutually engaged, thereby achieving the purpose of mutually connecting and fixing the first housing 3 and the second housing 4, so that the two are combined to form a complete power supply housing 1, and the battery assembly 2 is arranged in the internal cavity of the power supply housing 1. In this process, the second mounting plate 401 applies a force to the first mounting plate 301 in the direction of the battery assembly 2, and the force causes the first mounting plate 301 to deform in the direction of the battery assembly 2, so that the first mounting plates 301 on the opposite sides cooperate with each other to clamp and fix the battery assembly 2. In summary, the process of installing the first shell 3 and the second shell 4 to each other is also the process of clamping and fixing the battery assembly 2, thereby improving the structural firmness between the battery assembly 2 and the power supply shell 1, making it difficult for the two to loosen from each other due to bumps in daily life.

[0040] It is understandable that in order to further improve the structural strength between the battery assembly 2 and the power supply shell 1, an adhesive material (not shown in the drawings) can be provided between the battery assembly 2 and the power supply shell 1 to fix the position of the battery assembly 2 and the power supply shell 1 by utilizing the bonding properties of the adhesive material.

[0041] It should be added that, in order to further improve the connection firmness between the first shell 3 and the second shell 4, in addition to the connection through the first mounting plate 301 and the second mounting plate 401 mentioned above, snap-fit ​​positions are also provided at other positions of the first shell 3 and the second shell 4. Since the above-mentioned technology belongs to conventional technical means in this field, this application will not describe them one by one.

[0042] Furthermore, a plurality of first mounting plates 301 are provided on the same side; in this way, the plurality of first mounting plates 301 are combined with each other to further improve the structural firmness between the battery assembly 2 and the power supply housing 1. In this embodiment, three first mounting plates 301 are provided on the same side. It can be understood that since the first mounting plate 301 and the second mounting plate 401 are synchronously provided, three second mounting plates 401 are also provided on the same side.

[0043] Furthermore, the width of the second mounting plate 401 is greater than the gap width of the buckle gap 303; in this configuration, since the width of the second mounting plate 401 is greater than the gap width of the buckle gap 303, if the second mounting plate 401 is successfully inserted into the buckle gap 303, the second mounting plate 401 will inevitably exert a force on the first mounting plate 301 in the direction of the battery assembly 2, and use the force to deform the first mounting plate 301 in the direction of the battery assembly 2 to a certain extent, thereby deforming and expanding the gap width of the buckle gap 303, so that the second mounting plate 401 can be smoothly inserted into the buckle gap 303. At the same time, the first mounting plate 301 deformed in the direction of the battery assembly 2 can clamp and fix the battery assembly 2, thereby meeting the design requirements of this application.

[0044] Furthermore, the gap between the first mounting plates 301 on the two opposite sides is defined as the mounting gap, and the width of the battery assembly 2 is equal to the gap width of the mounting gap. In this way, before the second mounting plate 401 is inserted into the buckle gap 303, the first mounting plates 301 on the two opposite sides can pre-position the battery assembly 2, and during the process of inserting the second mounting plate 401 into the buckle gap 303, the battery assembly 2 does not change position relative to the power supply housing 1.

[0045] Further, the first snap fastener 302 includes a snap-fitting hole, and the second snap fastener 402 includes a snap-fitting member that is convexly arranged; or, the first snap fastener 302 includes a snap-fitting member that is convexly arranged, and the convex direction of the snap-fitting member is toward the side of the first mounting plate 301 that is away from the battery assembly 2, and the second snap fastener 402 includes a snap-fitting hole. In this arrangement, the snap-fitting member that is convexly arranged is snapped into the snap-fitting hole to achieve a mutually fixed connection between the first shell 3 and the second shell 4, and the structure is simple and practical. In this embodiment, the first snap fastener 302 is configured as a snap-fitting hole, and the second snap fastener 402 is configured as a snap-fitting member that is convexly arranged.

[0046] Furthermore, a reinforcing plate 304 is provided between the first mounting plate 301 and the first shell 3; at least two reinforcing plates 304 are provided, and at least two reinforcing plates 304 are respectively located on opposite sides of the first mounting plate 301. In such a configuration, considering that the first mounting plate 301 will undergo a certain position deformation during use, a reinforcing plate 304 is provided between the first mounting plate 301 and the first shell 3, and the reinforcing plate 304 is used to improve the connection strength between the first mounting plate 301 and the first shell 3, so as to avoid the connection between the first mounting plate 301 and the first shell 3 from breaking, causing the battery assembly 2 to loosen and shake relative to the power supply shell 1. Moreover, at least two reinforcing plates 304 are provided to further improve the connection strength between the first mounting plate 301 and the power supply shell 1. It can be understood that the setting position of the reinforcing plate 304 avoids the insertion area of ​​the second mounting plate 401 to prevent the position interference between the reinforcing plate 304 and the second mounting plate 401.

[0047] As a preferred solution of the above embodiment, refer to the attached Figure 1-3 , a wireless charging platform 5 is provided on the outside of the power housing 1, and a wireless charging component 6 is provided inside the power housing 1 corresponding to the wireless charging platform 5.

The induction coil 601 is arranged on the inner side of the annular ring of the annular magnet 602, and the induction coil 601 and the annular magnet 602 are arranged coaxially. In this way, the wireless charging component 6 is used to realize the wireless connection between the battery assembly 2 and the electronic device for wireless charging; at the same time, the wireless charging platform 5 is designed to be a planar structure as much as possible, so that electronic devices such as mobile phones can be stably placed on the surface of the wireless charging platform 5 for wireless charging. Among them, an annular magnet 602 is arranged on the outer side of the annular ring of the induction coil 601, and the magnetic characteristics of the annular magnet 602 are used to adsorb the electronic device to the wireless charging platform 5, so that the induction area of ​​the electronic device corresponds to the induction coil 601, thereby improving the efficiency of wireless charging.

[0048] As a preferred solution of the above embodiment, the mobile power supply further includes a connecting wire 7, the first end of which is fixedly connected to the power housing 1, and the first end of which is in communication with the current output port of the battery assembly 2; the second end of the connecting wire 7 is used to connect to the electronic device; in this way, the connecting wire 7 is used to realize a wired connection between the battery assembly 2 and the electronic device for wired charging. The second end of the connecting wire 7 includes a USB interface or a Type-C interface.

[0049] Further, see Attachment Figure 2The outside of the power supply housing 1 is provided with a socket portion 101 for accommodating the second end of the connecting wire 7, and the outside of the socket portion 101 is provided with a limiting groove 102 for limiting the connecting wire 7. In this way, the second end of the connecting wire 7 can be inserted into the socket portion 101 when not in use to form a hanging rope. The user can carry or move the mobile power supply by the hanging rope, which further improves the portability. At the same time, the limiting groove 102 for limiting the connecting wire 7 is provided on the outside of the socket portion 101 to improve the stability of the hanging rope and prevent the hanging rope from falling off during use.

[0050] As a preferred solution of the above embodiment, a charging interface 103 is provided on the outside of the power supply housing 1, and the charging interface 103 is interconnected with the current input port of the battery assembly 2; wherein the charging interface 103 includes but is not limited to one or more of a Lightning interface, a Mini USB interface, a Micro USB interface, and a Type-C interface. In this way, multiple types of charging interfaces 103 are used, so that the user can use a suitable charging interface 103 to connect the battery assembly 2 for charging according to the specific situation.

[0051] As a preferred solution of the above embodiment, a power indicator light 104 is provided on the outside of the power housing 1, and the power indicator light 104 is electrically connected to the battery assembly 2. Such a configuration facilitates the user to observe the remaining power of the battery assembly 2 through the power indicator light 104, and replenish the power of the battery assembly 2 in time to ensure that the mobile power supply can be used continuously.

[0052] Furthermore, a switch button 8 is provided on the outside of the power supply housing 1, and the switch button 8 is electrically connected to the power indicator light 104; with this arrangement, the power indicator light 104 can be manually turned on using the switch button 8, so that the user can observe the remaining power of the battery assembly 2 through the power indicator light 104 when the mobile power supply is not in use, and replenish the power of the battery assembly 2 in time to ensure that the mobile power supply can be used continuously.

[0053] Further, see Attachment Figure 6The switch button 8 includes a button cap 801 and a button arm 802 that can be elastically deformed; one end of the button arm 802 is fixedly arranged on the side of the button cap 801, and the other end of the button arm 802 is fixedly connected to the power housing 1. Specifically, the other end of the button arm 802 is fixedly connected to the power housing 1 through a fixing column 803; wherein an arc section 8021 is provided in the middle of the button arm 802. In this arrangement, when the user presses the button cap 801 to trigger the patch button of the circuit substrate located inside the power housing 1, the power indicator light 104 can be operated and controlled. Then, the button cap 801 returns to its original position under the elastic restoring force of the elastically deformable button arm 802. Among them, considering that the other end of the button arm 802 is fixedly connected to the power supply shell 1, in order to avoid the force applied to the connecting end of the button arm 802 and the power supply shell 1 during the process of pressing the button cap 801, which may cause looseness between the button arm 802 and the power supply shell 1; this embodiment provides an arc segment 8021 in the middle part of the button arm 802, and utilizes the arc segment 8021 as a bending node for elastic deformation of the button arm 802, that is, the bending deformation of the button arm 802 is concentrated on the length segment between the button cap 801 and the arc segment 8021, thereby reducing the influence of the connecting end of the button arm 802 and the power supply shell 1, and effectively avoiding looseness between the button arm 802 and the power supply shell 1.
