In some embodiments, referring to fig. 1, the boss 13 is stepped, and specifically, the sidewall of the boss 13 connects the first surface 12 and the second surface 131. Compared with the special-shaped protruding portion 13, the protruding portion 13 is in a regular shape, and is simpler in shape and convenient to machine and shape. Referring to fig. 2, the installation space 11 includes a first cavity 111 and a second cavity 112, and the first surface 12 is adjacent to the first cavity 111. One end surface of the boss 13 in the thickness direction of the housing 1 is a second surface 131, the second surface 131 is a lower surface of the boss 13 in the Z-axis direction shown in fig. 1, and the second surface 131 is adjacent to the second cavity 112 in the X-axis direction. It should be noted that, the first surface 12 is adjacent to the first cavity 111, and it is understood that the first surface 12 is close to the first cavity 111 relative to the second surface 131, as shown in fig. 2, and the first surface 12 is located below the first cavity 111; adjacent the second surface 131 to the second cavity 112 is understood that the second surface 131 is adjacent to the second cavity 112 relative to the first surface 12, as shown in fig. 2, the second surface 131 being located below the second cavity 112.

As can be seen from the foregoing, the thickness of the first cavity 111 is smaller than the thickness of the second cavity 112, and the housing 1 and the protruding portion 13 are integrally formed, and the protruding portion 13 protrudes from the first surface 12, so that the cross section of the protruding portion 13 is in a "U" shape, and for convenience of understanding, an end surface of the housing 1 opposite to the first surface 12 in the thickness direction (Z-axis direction) is defined as a third surface 14, and the third surface 14 is an upper surface of the housing 1 in the Z-direction shown in fig. 2. The thickness of the first cavity 111 is H1, the thickness of the second cavity 112 is H2, H1 is the distance between the first surface 12 and the third surface 14 in the Z direction, H2 is the distance between the second surface 131 and the third surface 14 in the Z direction, and H1 < H2. The thicknesses of the first cavity 111 and the second cavity 112 are different, so that the first cavity 111 and the second cavity 112 have a thickness difference in the Z direction, the power supply 2 is arranged in the first cavity 111 with smaller thickness, the position of the thickness difference is favorable for forming the heat dissipation space 3 with larger volume, and the thickness of the first cavity 111 is smaller, so that heat dissipation of the power supply 2 in the first cavity 111 is facilitated.

In some embodiments, referring to fig. 2, when the first surface 12 is partially abutted against the horizontal placement surface, an included angle is formed between the first surface 12 and the horizontal placement surface, for convenience of explanation, the included angle is defined as θ, in a desktop use state, the horizontal placement surface is a desktop, a space corresponding to the included angle θ is a heat dissipation space 3, and the mobile power source is abutted against the desktop at the included angle θ. It should be noted that, the smaller the included angle θ is in the range of 15 ° greater than θ > 1 °, the smaller the heat dissipation space 3 is, and when the included angle θ is 1 ° or more than θ > 0 °, the heat dissipation space 3 is smaller, which is inconvenient for heat dissipation of the power supply 2. When the included angle theta is more than or equal to 15 degrees, the inclination angle of the mobile power supply is larger, the mobile power supply is easy to be touched by an external force by mistake to topple over, and the stable placement of the mobile power supply is inconvenient. In the embodiment of the application as shown in fig. 2, the mobile power supply is leaned against the desktop at the included angle theta, and 15 degrees is more than theta and more than 1 degrees, so that the heat dissipation space 3 maintains certain heat dissipation efficiency, the mobile power supply maintains certain placement stability, and the use experience of a user is improved.

With continued reference to fig. 2, the first cavity 111 is located at the left end of the mobile power supply, and the second cavity 112 is located at the right end of the mobile terminal, and it will be understood that the "left" and "right" mentioned above do not represent actual use states, and the left end of the mobile power supply is only the end opposite to the direction of the arrow of the X axis in the position shown in fig. 2; the right end of the mobile power supply is only one end which is the same as the direction of the arrow of the X axis when the mobile power supply is at the position shown in fig. 2. The thickness of the second cavity 112 is smaller than that of the second cavity 112, so that when the mobile power supply is placed on a desktop, the left end of the mobile power supply is propped against the desktop and the right end of the mobile power supply is suspended under the action of gravity due to the fact that the load of the power supply 2 is large. The left end of the first surface 12, the protruding portion 13 and the table top form a triangular abutting structure. It should be noted that, a plurality of protruding portions 13 can be evenly arranged to hang the first surface 12 entirely, under the condition of arranging a plurality of protruding portions 13, the protruding portions 13 are in multi-point position and are propped against the tabletop, the first surface 12 is parallel to the tabletop, a larger interval exists between the mobile power source and the tabletop, heat of the power source 2 can be exchanged in the larger heat dissipation space 3, but the protruding portions 13 arranged at the multi-point positions enable the outer wall surface of the mobile power source to be not smooth enough, and are not beneficial to carrying by hand. Compared with the embodiment, the application has the advantages that the protruding part 13 with the step shape is arranged, so that the protruding part 13 and the left end of the first surface 12 support the mobile power supply together, thereby realizing the triangular stable abutting of the mobile terminal on the desktop, along with simple structure, convenient implementation and convenient hand-held carrying. The embodiment of the application is superior to the embodiment in portability, and meanwhile, the heat dissipation space 3 of the suspended part of the first surface 12 is spaced from the desktop to be capable of dissipating heat of the power supply 2, and in the embodiment of the application, the contact area of the mobile power supply and the desktop is smaller, so that the heat exchange efficiency of the mobile power supply and air is improved, and the heat dissipation efficiency of the mobile power supply is further improved.

Referring to the embodiment shown in fig. 2, the extension surface of the second surface 131 may intersect the first surface 12 to form an included angle, which is described in an application scenario where the mobile power supply is placed on a desktop for charging. In another embodiment, the second surface 131 may be parallel to the table top and rest entirely on the table top. In the heat dissipation effect, under the condition that the second surface 131 is attached to the table top, the second surface 131 is all abutted against the table top, so that heat of the components in the second cavity 112 is accumulated between the table top and the second surface 131, which is not beneficial to heat dissipation of the components in the second cavity 112. In the embodiment of the present application shown in fig. 2, the second surface 131 is parallel to the first surface 12 and has a suspending portion, and in the X-axis direction, the second surface 131 is suspended near the left end of the first cavity 111 and abuts against the tabletop and the right end.

It should be noted that, in the embodiment shown in fig. 2, the circuit board 4 is installed in the second cavity 112, the circuit board 4 is electrically connected to the power source 2, and the circuit board 4 is used for converting current, so that the mobile power source stably supplies power to the mobile terminal. The first surface 12 is abutted against the tabletop part to form a heat dissipation space 3 for dissipating heat of the power supply 2; the second surface 131 abuts against the tabletop portion to form a heat dissipation space 3 for dissipating heat from the circuit board 4.

In another embodiment, the boundary between the first surface 12 and the second surface 131 may be disposed at the middle of the first surface 12 in the X direction, or may deviate toward the left end of the first surface 12, where the smaller the length between the left end surface of the protruding portion 13 and the left end surface of the housing 1, the smaller the volume of the first cavity 111, and in the present application, the boundary between the first surface 12 and the second surface 131 is disposed near the right side of the housing 1, so that the length of the first cavity 111 is greater than the length of the second cavity 112, and the lengths of the first cavity 111 and the second cavity 112 represent the lengths in the X axis direction in fig. 2. Compared with the embodiment, the first cavity 111 has larger volume and can accommodate the power supply 2 with larger capacitance, so that the mobile power supply can supply power to the mobile terminal for many times with high power, and the compatibility of the mobile power supply is improved.
