[0002] A mobile power bank is a device used to charge mobile phones or laptops. It consists of multiple components, such as a key structure, display, and power supply. The key structure of a mobile power bank primarily includes a key body, key components, a control panel, and a baseboard. Pressing the key body simultaneously presses the key components, which then electrically connect to the control panel, generating signals that transmit commands and control the operation of the corresponding components.

[0003] There are many shapes of mobile power banks. For example, the shape of the mobile power bank with the application number 202121958431.0 filed by the applicant on August 19, 2021, and named as a new mobile power bank, is often arranged at the top or bottom (i.e., the corresponding patent Figure 1 However, when the button structure is set at the upper end or the lower end, there will be the following problems. First, the button structure is protruding, and the height of the button structure is higher than the height of the upper end surface of the mobile power bank, resulting in the button structure being accidentally touched when the side with the button structure is placed on the desktop. Since the button structure is electrically connected to the internal control board, each accidental touch will cause the control board to control the corresponding components to work, causing unnecessary trouble and worsening the user experience. Moreover, since the button structure is protruding, when the side with the button structure is placed on the desktop, it is easy to be uneven, and the mobile power bank cannot be placed flat.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Figures 1 to 8 The structure of a key structure of an embodiment of the present invention is schematically shown.

[0024] like Figures 1 to 8 As shown, a key structure includes a key body 1, a control board 2, a substrate 3, a key component 4 and a waterproof membrane 5.

[0025] The control board 2 can be installed on the back of the substrate 3, that is, the control board 2 is installed on Figure 1As shown, a key component 4 can be mounted on the lower end surface of the substrate 3 of the control board 2. The lower end surface of the key body 1 contacts the key component 4. A through hole 31 is integrally formed on the substrate 3. The key body 1 is mounted in the through hole 31, and the upper end surface of the key body 1 does not exceed the upper end surface of the substrate 3. A waterproof membrane 5 can be mounted between the key body 1 and the key component 4. In the present utility model, when the key body 1 is pressed, the key body 1 can drive the key component 4 to be pressed. The key component 4 is electrically connected to the control board 2. When the key component 4 is pressed, the key component 4 will send an electrical signal to the control board 2, and the control board 2 will control the corresponding components to work. Since the control method of the control board 2 does not fall within the scope of protection of the present utility model, the specific control method will not be described in the present utility model.

[0026] Combine Figure 2 and Figure 5 As can be seen, three positioning posts 11 are integrally formed on the lower end surface of the key body 1, and three first through-holes 51 are formed at corresponding positions on the waterproof membrane 5. The three positioning posts 11 can pass through the first through-holes 51 of the waterproof membrane 5 and contact the control board 2 (of course, in the absence of external force, there is a certain gap between the three positioning posts 11 and the control board 2). The control board 2 can also support the positioning posts 11. When the key body 1 is not pressed, the three positioning posts 11 do not contact the control board 2, and there is a certain gap between the three positioning posts 11 and the control board 2. When the key body 1 is pressed, the three positioning posts 11 come into contact with the control board 2. Therefore, the travel of the key body 1 is equal to the height of the gap between the three positioning posts 11 and the control board 2.

[0027] like Figure 2 、 Figure 7 and Figure 8 As shown, a column button 41 is installed in the middle position of the button component 4, a recessed hole 13 is provided in the middle position of the lower end of the button body 1, and a corresponding second through hole 52 is provided in the middle position of the waterproof membrane 5. The column button 41 passes through the second through hole 52 and is located in the recessed hole 13 of the button body 1. When the button body 1 is pressed, the recessed hole 13 of the button body 1 can drive the column button 41 downward to a certain extent, so that the column button 41 will be pressed. At this time, the column button 41 can give an electrical signal to the control board 2, and the control board 2 controls the corresponding components to work.

[0028] like Figure 2As shown, a first step surface 32 is integrally formed at the through hole 31 of the substrate 3. The first step surface 32 can make the width of the upper end of the through hole smaller than the width of the lower end of the through hole. Correspondingly, a second step surface 12 is integrally formed on the key body 1. The second step surface 12 can make the width of the upper end of the key body 1 smaller than the width of the lower end of the key body 1. The first step surface 32 can resist the second step surface 12. In this way, the key body 1 can be stuck in the through hole 31 of the substrate 3, and after the key body 1 is installed, the key body 1 will not fall off from the through hole 31.

[0029] like Figure 2 and Figure 4 As shown, a fixing post 33 can be provided on the back of the base plate 3. A mounting hole is formed in the control board 2, through which the fixing post 33 can pass. Therefore, the fixing post 33 can secure the control board 2 and the base plate 3 together, preventing them from becoming detached and affecting their use. More specifically, the fixing post 33 can be provided with threads, so that the control board 2 and the base plate 3 can be secured together by screws.

[0030] like Figure 1 As shown, a USB-A / USB-C through hole is integrally formed on the substrate 3, and a sound through hole is also integrally formed on the substrate 3. A corresponding sound module can be installed on the control board 2, and the sound generated by the sound module can be emitted through the sound through hole.

[0031] In the present invention, a waterproof membrane 5 is provided between the key body 1 and the key component 4. The waterproof membrane 5 is made of a waterproof material and can play a waterproof role. The waterproof membrane 5 will be tightly attached to the back of the key body 1. Water on the key body 1 will be blocked by the waterproof membrane 5, and water cannot enter the interior of the mobile power bank from the key body 1, which is equivalent to waterproofing the key body 1. In addition, the height of the upper end surface of the key body 1 does not exceed the height of the upper end surface of the substrate 3. The substrate 3 is part of the mobile power bank and is provided at the upper or lower end of the mobile power bank. When the substrate of the mobile power bank is placed on a desktop or other object, the key body 1 will not be accidentally touched, and its use will not be affected by unevenness.

[0032] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
