The display end of the digital tube 150 can be used to display information such as the power and temperature of the battery 120, so as to facilitate the user to monitor the state of the portable charging device 1 in real time. In different charging devices, the internal electronic components of the device body 10 are different, and no limitation is made here.

[0039] Please refer to Figures 2 - 4, one end of the connecting device 20 can be connected to the device body 10, and the other end is detachably connected to the connecting device 20 itself to form a wearable space. The user can connect the portable charging device 1 to an external object, such as the user's backpack or pocket, etc., through the wearable space. Specifically, the connecting device 20 can include a connecting member 210 and a fixing module 70. The connecting member 210 can be set as a bendable structure, and the fixing module 70 can be arranged on the connecting member 210. It should be noted that in this embodiment, the fixing module 70 has a partial area that can be fixedly connected to the connecting member 210, and the fixing module 70 also has another partial area that can be detachably connected to the connecting member 210, so as to form a wearable space when the connecting member 210 is bent.

[0040] The embodiment of the present application does not limit the specific form of the connecting member 210. For example, it can be a belt body or other bendable elements, and can be specifically set according to the actual situation.

[0041] Furthermore, in one implementation, one end of the connecting member 210 can extend into the device body 10, and a connecting mechanism 211 for connecting to the device body 10 can be arranged at the end of the connecting member 210 extending into the device body 10. The connecting member 210 can be connected to the device body 10 through the connecting mechanism 211. The embodiment of the present application does not limit the specific form of the connecting mechanism 211. For example, in one implementation, the connecting mechanism 211 can be a connecting hole, and a connecting pin matching the connecting hole can be arranged inside the device body 10. The connecting pin can be inserted into the connecting hole to realize the fixation of the connecting mechanism 211 and the device body 10, and can be specifically set according to the actual situation, and is not limited here.

[0042] It should be noted that the embodiment of the present application does not limit the specific structure and specific setting position of the fixing module 70. For example, in one implementation, the fixing module 70 can be a spring hook. When the connecting member 210 is bent, the fixing module 70 can be hooked on the connecting member 210 to form a wearable space. At the same time, the fixing module 70 can be arranged at the end of the connecting member 210, which is beneficial to increasing the area of the wearable space to adapt to more application scenarios.

[0043] Specifically, in one implementation, the fixing module 70 can include a first fixing unit 220 and a second fixing unit 230. Both the first fixing unit 220 and the second fixing unit 230 can be arranged on the connecting member 210, and the first fixing unit 220 and the second fixing unit 230 can be arranged at intervals from each other. The first fixing unit 220 and the second fixing unit 230 can be detachably connected, which is convenient for forming a wearable space.

[0044] Furthermore, please continue to refer to Figure 3, in one embodiment, the connector 210 may be provided with a plurality of mounting positions 30, and each mounting position 30 can be used to connect with the first fixing unit 220 or the second fixing unit 230. That is to say, in this embodiment, the first fixing unit 220 and the second fixing unit 230 can be connected and arranged on the mounting position 30.

[0045] Specifically, in this embodiment, the mounting position 30 may include a positioning portion 310 provided on the connector 210, and the positioning portion 310 can be used to fix the first fixing unit 220 and the second fixing unit 230 on the mounting position 30. Specifically, taking the first fixing unit 220 as an example, in one embodiment, the first fixing unit 220 may be provided with a wire passing through groove (not shown in the figure) that cooperates with the positioning portion 310. It should be noted that the connector 210 can pass through the wire passing through groove, and the positioning portion 310 can be embedded into the wire passing through groove and be in pressing connection with the wire passing through groove to achieve the fixation between the first fixing unit 220 and the connector 210. It can be understood that in one embodiment, the second fixing unit 230 can adopt the above structure to be fixed with the connector 210, which will not be elaborated here. It should be noted that the embodiments of the present application do not limit the specific connection manner between the first fixing unit 220 and the second fixing unit 230 and the connector 210. For example, in one embodiment, only the first fixing unit 220 may be connected to the connector 210 in the above manner. In another embodiment, only the second fixing unit 230 may be connected to the connector 210 in the above manner. In yet another embodiment, both the first fixing unit 220 and the second fixing unit 230 may be connected to the connector 210 in the above manner.

[0046] In this embodiment, the first fixing unit 220 and the second fixing unit 230 can be spaced apart and arranged on the connector 210. When the connector 210 is bent, the first fixing unit 220 and the second fixing unit 230 can be detachably connected to form a ring structure (i.e., a wearable space), and this ring structure can be used to connect with external objects. For example, this ring structure can be hung on the user's pocket or the shoulder strap of the user's backpack, etc., so as to facilitate the user to carry the portable charging device 1 and the portable charging device 1 does not occupy the space of the user's pocket or backpack, which is beneficial to improving the space utilization rate of the user's pocket or backpack, etc.

[0047] The embodiments of the present application do not limit the specific form of the detachable connection between the first fixing unit 220 and the second fixing unit 230.

In another embodiment, the first fixing unit 220 can be a magnetic member and the second fixing unit 230 can be a magnetic metal. In still another embodiment, both the first fixing unit 220 and the second fixing unit 230 can be magnetic members, which can be specifically set according to the actual situation and are not limited herein.

[0048] In addition, in another embodiment of the embodiments of the present application, the first fixing unit 220 and the second fixing unit 230 can also be detachably snapped. For example, the first fixing unit 220 and the second fixing unit 230 can be detachably snapped by providing a slot and a block, or for another example, the first fixing unit 220 and the second fixing unit 230 can be detachably snapped by two hooks, or for still another example, the first fixing unit 220 and the second fixing unit 230 can be detachably snapped by an interference fit method, etc., which can be specifically set according to the actual situation.

[0049] Specifically, please refer to Figures 4 - 6 , in this embodiment, the first fixing unit 220 can include a first connection block 221. The first connection block 221 can be connected to the connecting member 210, and the first connection block 221 can be provided with a slot 2211. The second fixing unit 230 can include a second connection block 231. A latching assembly 2311 is movably provided on the second connection block 231. The latching assembly 2311 is detachably latched in the slot 2211, that is to say, the latching assembly 2311 can selectively be inserted into the slot 2211 and be latched with or disengaged from the slot 2211 to achieve the detachable latching between the first fixing unit 220 and the second fixing unit 230.

[0050] Furthermore, please refer to Figure 7 and Figure 8 simultaneously, the latching assembly 2311 can include at least one latching member 40 and a reset member 2311c connected to the latching member 40. The latching member 40 can be used to latch with the slot 2211, and the reset member 2311c can be used to reset the latching member 40.

[0051] Specifically, the engaging member 40 can be provided with an engaging portion 2311a that is engaged with the card slot and a driving portion 2311b for driving the movement of the engaging member 40. The engaging portion 2311a can be slidably disposed on the second connecting block 231. During the process of the engaging portion 2311a sliding on the second connecting block 231, the engaging portion 2311a can be selectively engaged in or disengaged from the card slot 2211. Specifically, the engaging portion 2311a is a hook-shaped structure. The engaging portion 2311a has a connecting portion and a hook portion protruding from the connecting portion. The hook portion hooks the slot wall of the card slot 2211 to achieve the engagement between the engaging portion 2311a and the card slot 2211. The driving portion 2311b can be used to drive the sliding of the engaging portion 2311a under the action of an external force. In this embodiment, one end of the driving portion 2311b can extend out of the surface of the second connecting block 231, which is convenient for the user to press the driving portion 2311b to drive the movement of the engaging portion 2311a. The specific structure of the driving portion 2311b is not limited in the embodiment of the present application. For example, it can be set to an "L"-shaped structure, which is more convenient for the user to install the driving portion 2311b by hand. It can be understood that the driving portion 2311b can also be set to other shapes according to the user's preference, which is not limited here.

[0052] The reset member 2311c can be connected to the engaging portion 2311a and is used to reset the engaging portion 2311a after the external force disappears. Specifically, when the reset member 2311c is in a natural state, the engaging portion 2311a can be engaged in the card slot 2211 and lock the first fixing unit 220 and the second fixing unit 230 together. When the reset member 2311c is in a compressed state under the action of an external force, at this time, the engaging portion 2311a can be disengaged from the card slot 2211 and unlock the first fixing unit 220 and the second fixing unit 230.

[0053] It should be noted that the embodiment of the present application does not limit the number of the engaging portion 2311a and the driving portion 2311b. For example, it can be one, or two, etc., and can be specifically set according to the actual situation.

[0054] Please continue to refer to Figure 7 and Figure 8, in one embodiment, two engaging members 40 may be provided. The two engaging members 40 may be arranged oppositely, and the engaging portions 2311a on the engaging members 40 are arranged staggeredly. Specifically, the engaging member 40 includes a main body portion (not shown in the figure). The driving portion 2311b and the engaging portion 2311a are respectively arranged at both ends of the main body portion and are respectively perpendicular to the main body portion. An avoidance portion is adjacently arranged at the connection portion of the main body portion and the engaging portion 2311a. The avoidance portion is a groove portion and penetrates through the side wall of the main body portion. The two engaging members 40 are arranged oppositely, and the two engaging portions 2311a are arranged staggeredly. The hooking directions of the two engaging portions are opposite. The staggered arrangement of the two engaging portions 2311a means that one engaging portion 2311a is arranged in the avoidance portion on the other engaging member 40, so that the two engaging portions 2311a are respectively located in the avoidance portions of the engaging members 40. Since a reset member 2311c is arranged between the two engaging members 40, under the drive of an external force, the two engaging portions 2311a respectively move in the avoidance grooves of the other engaging member 40, so that the distance between the hook portions of the two engaging portions 2311a becomes smaller, and the engaging portion 2311a can extend into or disengage from the card slot 2211 through the through hole 2312a with a fixed size. In the natural state, the distance between the two hook portions is greater than the maximum diameter of the through hole 2312a. Under the drive of an external force, the distance between the two hook portions is less than the maximum diameter of the through hole 2312a. The engaging portions 2311a of the two engaging members 40 may be arranged staggeredly. When the engaging portion 2311a of one engaging member 40 moves in the first direction and is engaged with the card slot 2211, the engaging portion 2311a of the other engaging member 40 moves in the opposite direction of the first direction and is engaged with the card slot 2211. In this embodiment, the reset member 2311c may be a spring, and the reset member 2311c may be arranged between the two engaging members 40. For the convenience of description and distinction, one of the engaging members 40 will be hereinafter referred to as the first engaging member 41, the other engaging member 40 will be referred to as the second engaging member 42, the driving portion 2311b on the first engaging member 41 will be referred to as the first driving portion 51, the engaging portion 2311a on the first engaging member 41 will be referred to as the first engaging portion 61, the driving portion 2311b on the second engaging member 42 will be referred to as the second driving portion 52, and the engaging portion 2311a on the second engaging member 42 will be referred to as the second engaging portion 62.

[0055] The first driving portion 51 and the second driving portion 52 can be used to drive the first engaging member 41 and the second engaging member 42 to move towards each other under the drive of an external force. When the first engaging member 41 and the second engaging member 42 move towards each other, the first engaging portion 61 and the second engaging portion 62 can respectively disengage from the card slot 2211, so that the first fixing unit 220 and the second fixing unit 230 can be unlocked. When the first driving portion 51 and the second driving portion 52 lose the drive of an external force, the first engaging member 41 and the second engaging member 42 move away from each other under the action of the reset member 2311c, and the first engaging portion 61 and the second engaging portion 62 can respectively be engaged with the card slot 2211. At this time, the first fixing unit 220 and the second fixing unit 230 can be locked.

[0056] It should be noted that the specific form of the reset member 2311c is not limited in the embodiments of the present application. In addition to the present embodiment where the reset member 2311c can be set as a spring, in another embodiment, the reset member 2311c can also be set as a shrapnel, which can be specifically set according to the actual situation and will not be limited here.

[0057] In addition, the specific structure of the first connection block 221 is not limited in the embodiments of the present application.
