[0027] The present utility model embodiment provides a mobile power supply 100, referring to Figure 1 and Figure 2 The mobile power supply 100 includes a housing 10, a charging module 20 and a touch sensing component 30. The housing 10 has a mounting cavity 11, and a sensing area 12 (eg, Figure 1 The charging module 20 is disposed in the mounting cavity 11, and the charging module 20 includes a main board 21 and a switch circuit disposed on the main board 21. The touch sensing component 30 is disposed in the sensing area 12 and is electrically connected to the switch circuit. The touch sensing component 30 can trigger the switch circuit when the sensing area 12 is touched.

[0028] Among them, the housing 10 includes, for example, a front housing and a rear housing, and the front housing and the rear housing together enclose a mounting cavity 11. The sensing area 12 can be set according to the user's usual picking habits, so that the sensing area is located in an area on the surface of the housing 10 that is easily touched by the user, for example, the sensing area 12 is set on the main surface that the user usually touches when picking up the mobile power supply 100, or the sensing area 12 can be set on the side of the housing 10, or the sensing area 12 can be set on multiple surfaces of the housing 10. In order to facilitate the user to know the location of the sensing area 12, stickers or different color patterns can be set corresponding to the sensing area 12 for identification. Of course, in order to ensure the integrity of the appearance of the mobile power supply 100, no additional identification can be made so that the sensing area 12 is consistent with other areas on the housing 10. The charging module 20 includes, for example, a battery for power supply, a charging management circuit for adjusting the charging current, a current output circuit for outputting the charging current, etc., and the corresponding electronic components can be set on the main board 21. The switch circuit is used to control the switch state of the mobile power supply 100. For example, when the switch circuit is not triggered, the mobile power supply 100 is in the off state. When the switch circuit is triggered, the mobile power supply 100 enters the standby state. When the device to be charged is connected to the mobile power supply 100, the charging function is activated for charging. If no device to be charged is connected after entering the standby state for a predetermined time, the mobile power supply 100 is turned off and waits for the switch circuit to be triggered again before entering the standby state. The touch sensing component 30 is, for example, a capacitive sensor. Since the touch sensing component 30 is set corresponding to the sensing area 12, when the user touches the sensing area 12, the touch sensing component 30 can sense the user's touch and thus trigger the switch circuit, so that the mobile power supply 100 is awakened.

[0029] Therefore, compared with the traditional push-button switch, the mobile power supply 100 provided in this embodiment adopts touch wake-up, and can be automatically awakened by just touching the sensing area 12, which is more convenient to use.

[0030] In some embodiments, the touch sensing component 30 is disposed in the mounting cavity 11 , which can ensure the integrity and aesthetics of the housing 10 , prevent interference with normal charging, and provide certain protection for the touch sensing component 30 .

[0031] In some embodiments, reference Figure 2 The touch sensing component 30 includes a sensing element 31 and a conductive connector 32. The sensing element 31 abuts against the housing 10. The conductive connector 32 is connected between the sensing element 31 and the mainboard 21, and the conductive connector 32 is electrically connected to the sensing element 31 and the switch circuit respectively. The sensing element 31 is, for example, a thin sheet material with good conductivity, and the conductive connector 32 can be, for example, a wire, a conductive needle, etc. The sensing element 31 abuts against the housing 10, so that when the user touches the sensing area 12, the potential of the sensing element 31 changes, thereby triggering the switch circuit through the conductive connector 32.

[0032] In some embodiments, the conductive connection member 32 is an elastic conductive member, which is sandwiched between the sensing element 31 and the mainboard 21 in a compressed state. The sensing element 31 abuts against the housing 10 through the elastic conductive member. The elastic conductive member can be, for example, a pogo pin. After the mobile power supply 100 is assembled, the elastic conductive member will support the sensing element 31 so that the sensing element 31 abuts against the housing 10 to better sense the user's touch.

[0033] In some embodiments, the sensing element 31 is a copper sheet. When the mobile power supply 100 is working, the temperature of the internal electronic components is high, which is usually not easy to dissipate quickly, which will affect the performance and life of the electronic components. Since copper has good electrical conductivity and good thermal conductivity, and the sensing element 31 abuts the housing 10, the sensing element 31 can sense the user's touch while dissipating the heat of the internal electronic components. Alternatively, a heat dissipation material layer can be set on the side of the sensing element 31 away from the mainboard 21. The heat dissipation material layer is, for example, a graphene material, which can achieve a better heat dissipation effect.

[0034] In some embodiments, the touch sensing component 30 further includes an insulating layer 33, which is disposed between the mainboard 21 and the sensing element 31, and the insulating layer 33 at least covers one of the mainboard 21 or the sensing element 31. The insulating layer 33 can be provided to prevent the charge on the sensing element 31 from interfering with other electronic components on the mainboard 21. The insulating layer 33 is, for example, consistent with the shape of the sensing element 31, or slightly larger than the sensing element 31, so that the insulating layer 33 at least covers the sensing element 31 to more comprehensively shield the sensing element 31. Alternatively, the area of ​​the insulating layer 33 is larger than the area of ​​the mainboard 21, so that the insulating layer 33 at least covers the mainboard 21 to more comprehensively shield the mainboard 21. For example, the insulating layer 33 can also be made of an insulating material with good thermal conductivity, such as alumina ceramics, which can assist in heat dissipation.

[0035] In some embodiments, the insulating layer 33 is provided with a avoidance hole 331, and the conductive connector 32 passes through the avoidance hole 331. The avoidance hole 331 makes it easier to install the conductive connector 32, especially when the conductive connector 32 adopts a spring pin structure.

[0036] In some embodiments, the mobile power supply 100 further includes a magnetic component 40, which is disposed in the mounting cavity 11. The housing 10 has a first surface 13, and the device to be charged can be magnetically connected to the first surface 13 through the magnetic component 40. The sensing area 12 is disposed on the first surface 13. Since the first surface 13 is used to contact the device to be charged and has a large area, disposing the sensing area 12 on the first surface 13 can make the sensing area 12 larger and easier to be touched to achieve automatic wake-up.

[0037] Specifically, refer to Figure 1 The housing 10 has a top 15 and a bottom 16 opposite to each other, the magnetic component 40 is arranged near the top 15, the first surface 13 includes a magnetic area 17 covering the magnetic component 40, and the sensing area 12 is located on the side of the magnetic area 17 near the bottom 16. When a user takes the mobile power supply 100, they usually take it with the magnetic area 17 at the top, that is, the top 15 faces upward and the bottom 16 faces downward. At this time, the area near the bottom 16 of the housing 10 has a larger contact area with the user's hand, and it is easier to sense touch when the sensing area 12 is arranged near the bottom 16.

[0038] In some embodiments, the magnetic attraction area 17 includes an annular magnetic attraction area 171 and a positioning magnetic attraction area 172, and the positioning magnetic attraction area 172 is located on the side of the annular magnetic attraction area 171 close to the bottom end 16. The sensing area 12 is located on the side of the positioning magnetic attraction area 172 away from the annular magnetic attraction area 171. The corresponding magnetic attraction component 40 includes an annular magnetic attraction portion 41 and a positioning magnetic attraction portion 42. The annular magnetic attraction portion 41 is formed by, for example, a plurality of magnets arranged in a circumferential direction. The annular magnetic attraction portion 41 performs the main adsorption function, and the positioning magnetic attraction portion 42 adjusts the fixed direction of the device to be charged. The annular magnetic attraction area 171 is an area covering the annular magnetic attraction portion 41, and the positioning magnetic attraction area 172 is an area covering the positioning magnetic attraction portion 42. The sensing area 12 is specifically located below the positioning magnetic attraction area 172, which can reduce the interference of the magnetic attraction component with the touch sensing component 30.

[0039] In some embodiments, the charging module 20 further includes a wireless charging component 22, which is disposed in the mounting cavity 11 and electrically connected to the switch circuit, and the annular magnetic attraction portion 41 is disposed on the outside of the wireless charging component 22. The wireless charging component 22 may include, for example, a wireless receiving coil or a wireless transmitting coil, and when the switch circuit is triggered, the wireless charging component 22 enters a standby state, and when an external electronic device is wirelessly connected to the mobile power supply 100, the wireless charging component 22 may charge the external electronic device, or the external electronic device may reversely charge the mobile power supply 100.

[0040] In some embodiments, reference Figure 3 The mobile power supply 100 further includes a bracket assembly 50. The housing 10 has a first surface 13 and a second surface 14 opposite to each other. The bracket assembly 50 is rotatably disposed on the second surface 14, and the sensing area 12 is disposed on the first surface 13. The bracket assembly 50 can support the mobile power supply 100 so that when an external device is placed on the mobile power supply 100, it can be placed at a specific angle for normal use. Since users usually regard the side where the bracket assembly 50 is located as the back side, the sensing area 12 is disposed on the mobile power supply 100 opposite to the bracket assembly 50, that is, the sensing area 12 is disposed on the front side of the mobile power supply 100, which is more convenient to operate.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
