DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] like Figure 1-2 As shown, a first aspect of an embodiment of the present application provides a charging device 200 , which is used to charge an electronic device. The charging device 200 includes a housing 210 , a charging assembly, and a folding bracket 100 .

[0021] The housing 210 is used to accommodate the charging assembly. The housing 210 may be made of plastic, so that the housing 210 has a low cost, a low weight, and an insulating effect. The housing 210 may also be made of metal, so that the housing 210 is more durable and has a higher strength.

[0022] The charging assembly is arranged in the housing 210, and the housing 210 can play a certain protective role for the charging assembly. The charging assembly can be a battery cell assembly 220, and the battery cell assembly 220 can store electrical energy to charge the electronic device. In this case, the charging device 200 can be a mobile power supply. Alternatively, the battery cell assembly 220 can be a rectifier assembly, and the rectifier assembly can rectify AC power into DC power to charge the electronic device. In this case, the charging device 200 can be a charging stand. Alternatively, the battery cell assembly 220 can include both the battery cell assembly 220 and the rectifier assembly. In addition to being able to charge the electronic device, the rectifier assembly can also charge the battery cell assembly 220. In this case, the charging device 200 has the functions of both a charger and a mobile power supply.

[0023] The folding bracket 100 is connected to the housing 210. The folding bracket 100 can be folded or unfolded. When the folding bracket 100 is folded, it takes up less space, so it is easy to carry. When the folding bracket 100 is unfolded, it can support the housing 210, so that the housing 210 can maintain a certain tilt angle. When charging the electronic device, the charging device 200 can maintain a certain tilt angle of the electronic device, thereby playing the role of a bracket. The electronic device can be exemplarily a mobile phone, a tablet, etc., so that the user can conveniently watch the screen of the electronic device while charging.

[0024] In some embodiments, the housing 210 has a storage slot, and the folding bracket 100 can be stored in the storage slot, so that when the folding bracket 100 is stored, the appearance of the charging device 200 is more regular and convenient to carry. At the same time, the folding bracket 100 is stored in the storage slot, which can also provide a certain degree of protection for the folding bracket 100.

[0025] like Figure 3 As shown, in some embodiments, the charging device 200 also includes a wireless charging module 230 and a magnetic module 240. The wireless charging module 230 is disposed in the housing 210 and connected to the battery core assembly 220. The wireless charging module 230 is used to wirelessly charge the electronic device, so that the charging device 200 does not need to integrate a charging cable, or the user does not need to carry a charging cable separately. The magnetic module 240 is disposed in the housing 210 and is used to be magnetically connected to the electronic device, so that the electronic device and the charging device 200 can be magnetically attracted together, making wireless charging more stable and less likely to be interrupted, which is beneficial for users to use electronic devices while charging. Moreover, the magnetic module 240 is also beneficial for the alignment of the electronic device with the wireless charging module 230, thereby improving the charging efficiency.

[0026] like Figure 3 As shown, a second aspect of an embodiment of the present application provides a folding bracket 100 , and the folding bracket 100 includes a base 110 , a guide member 120 and a folding member 130 .

[0027] The base 110 can be connected to the housing 210 of the charging device 200 to support the charging device 200. The base 110 can also be a part of the housing 210, in which case the folding bracket 100 and the charging device 200 are integrally arranged. Alternatively, the base 110 can be arranged independently of the housing 210, in which case the folding bracket 100 and the charging device 200 are separately arranged, and the connection method between the base 110 and the housing 210 can be screw connection, magnetic connection, clamping connection, bonding, etc. The material of the base 110 can be plastic, metal, etc., which is not limited here. It should be noted that the base 110 can also be directly connected to the electronic device to serve as a bracket for the electronic device.

[0028] The guide member 120 is disposed on the base 110 , and the guide member 120 and the base 110 may be connected by screw connection, magnetic connection, clamping connection, bonding, integral molding, etc.

[0029] like Figure 3-4 As shown, the folding member 130 includes a sliding portion 131, a first folding portion 132 and a second folding portion 133 connected in sequence, the sliding portion 131 is slidably disposed on the guide member 120, and the guide member 120 is used to limit the sliding direction of the sliding portion 131. The first folding portion 132 has a first end 1321 close to the sliding portion 131 and a second end 1322 close to the second folding portion 133, the first end 1321 is rotatably connected to the sliding portion 131, that is, the first folding portion 132 can rotate relative to the sliding portion 131, and the first folding portion 132 and the sliding portion 131 can be rotatably connected by a rotating shaft or the like. The second end 1322 is rotatably connected to the second folding portion 133, that is, the first folding portion 132 can rotate relative to the second folding portion 133, and the first folding portion 132 and the second folding portion 133 can be rotatably connected by a rotating shaft or the like. One end of the second folding portion 133 away from the first folding portion 132 is rotatably connected to the guide member 120 , and the second folding portion 133 can rotate relative to the guide member 120 . The second folding portion 133 and the guide member 120 can be rotatably connected by a rotating shaft or the like.

[0030] The folding member 130 has a folded position and an unfolded position. Figure 2 As shown in FIG. 1 , when the folding member 130 is in the folded position, the folding bracket 100 is in the stowed state. When the folding member 130 is in the unfolded position, the folding bracket 100 is in the supporting state. Figure 5 As shown, when the sliding part 131 is pushed downward in a direction close to the second folding part 133, the sliding part 131 moves downward along the guide member 120, the angle between the first folding part 132 and the sliding part 131 changes, the angle between the second folding part 133 and the first folding part 132 changes, and the angle between the guide member 120 and the second folding part 133 changes, that is, the second folding part 133 and the first folding part 132 are tilted relative to the base 110, so that the folding member 130 can be switched from the folding position to the unfolded position, or from one unfolded position to another unfolded position. When the sliding part 131 is pushed upward in a direction away from the second folding part 133, the sliding part 131 moves upward along the guide member 120, so that the folding member 130 can be switched from the unfolded position to the folded position, or from one unfolded position to another unfolded position.

[0031] When the folding member 130 is in the folded position, the sliding portion 131, the first folding portion 132 and the second folding portion 133 are parallel to the base 110. When the sliding portion 131, the first folding portion 132, the second folding portion 133 and the base 110 are substantially in the shape of a sheet or plate, the plane where the sliding portion 131 is located, the plane where the first folding portion 132 is located and the plane where the second folding portion 133 is located are parallel to the plane where the base 110 is located. The plane where the sliding portion 131 is located is the plane where the sliding portion 131 is perpendicular to the thickness direction, the plane where the first folding portion 132 is located is the plane where the first folding portion 132 is perpendicular to the thickness direction, the plane where the second folding portion 133 is located is the plane where the second folding portion 133 is perpendicular to the thickness direction, and the plane where the base 110 is located is the plane where the base 110 is perpendicular to the thickness direction. The sliding part 131, the first folding part 132, and the second folding part 133 can be arranged in close contact with the base 110, so that the sliding part 131, the first folding part 132, and the second folding part 133 are more compact when stored with the base 110. The sliding part 131, the first folding part 132, and the second folding part 133 can be arranged at intervals with the base 110, so as to reduce wear when stored.

[0032] When the folding member 130 is in the unfolded position, the plane where the sliding portion 131 is located is set at an angle with the plane where the first folding portion 132 is located, the plane where the first folding portion 132 is located is set at an angle with the plane where the second folding portion 133 is located, and the plane where the second folding portion 133 is located is set at an angle with the plane where the guide member 120 is located. The first folding portion 132, the second folding portion 133 and the guide member 120 are in a triangular ring shape, so that they can support the base 110. At the same time, the triangular ring structure is also conducive to the user's grip, thereby playing the role of a finger ring buckle, which is convenient for the user to take.

[0033] like Figure 3As shown, in some embodiments, the folding bracket 100 further includes a first stopper 140 and a second stopper 150, the first stopper 140 is disposed on the base 110 or the guide member 120, and the second stopper 150 is disposed on the sliding portion 131, and the first stopper 140 can be limitedly matched with the second stopper 150, so that the sliding portion 131 is positioned relative to the guide member 120 at least one of the folding position and the unfolding position, so that the folding bracket 100 is relatively stable in the folding position or the unfolding state, and the support strength is relatively high. Exemplarily, the first stopper 140 can be a stopper column, and the second stopper 150 can be a stopper hole, and the stopper column is inserted into the stopper hole to achieve stopper matching. Or the first stopper 140 can be a magnetic member, and the second stopper 150 is also a magnetic member, for example, the first stopper 140 is a permanent magnet, and the second stopper 150 is a permanent magnet or an iron sheet, and the two magnetic members are limitedly matched by magnetic adsorption. By means of magnetic limiting, the first limiting member 140 and the second limiting member 150 can be matched for limiting more conveniently, the wear during the limiting matching is relatively small, and the limiting can be used repeatedly, and the strength of the limiting can be adjusted by changing the size of the designed magnetic force. It is understandable that when the sliding resistance between the sliding part 131 and the guide member 120 is large, the first limiting member 140 and the second limiting member 150 may not be provided, and the limiting can be performed by relying on the sliding resistance between the sliding part 131 and the guide member 120.

[0034] like Figure 3 As shown, in some embodiments, the first limit member 140 includes a plurality of sub-limit members 141 disposed on the guide member 120, and the plurality of sub-limit members 141 are spaced apart along the extension direction of the guide member 120, and each sub-limit member 141 can cooperate with the second limit member 150 for limiting. The folding member 130 has multiple unfolding positions, and different sub-limit members 141 correspond to different unfolding positions. When different sub-limit members 141 cooperate with the second limit member 150 for limiting, the angle between the sliding portion 131 and the first folding portion 132 is different, that is, the angle between the first folding portion 132 and the second folding portion 133 changes, and the angle between the second folding portion 133 and the guide member 120 changes. At this time, the inclination angle of the base 110 changes, so that the folding bracket 100 has multiple support gears. As shown in FIG. Figure 5-7 As shown, the second limiting member 150 is limitedly matched with different sub-limiting members 141 , and the sliding portion 131 is located at different positions of the guide member 120 , so that the shape of the folding member 130 can be changed, thereby changing the support angle of the folding bracket 100 .

[0035] like Figure 3As shown, in some embodiments, the guide member 120 includes a slide rail bracket 121 and a slide rail 122. The slide rail bracket 121 is disposed on the base 110. The slide rail bracket 121 is used to support the slide rail 122 and connect the slide rail 122 to the base 110. The material of the slide rail bracket 121 can be metal, thereby improving the strength of the guide member 120.

[0036] The slide rail 122 is arranged on the slide rail bracket 121, and the sliding part 131 is slidably arranged on the slide rail 122, and the sliding part 131 is anti-detachably connected to the slide rail 122 in a direction perpendicular to the sliding direction. The material of the slide rail 122 can be polyformaldehyde, which has good wear resistance and self-lubricating properties, so it is relatively wear-resistant, and the sliding part 131 is relatively smooth when sliding relative to the slide rail 122. The first limiter 140 is arranged on the slide rail 122, so that the distance between the second limiter 150 and the first limiter 140 is relatively close, which is conducive to the first limiter 140 and the second limiter 150 to perform limiting cooperation. When the folding member 130 is in the folded position, the first folding part 132 can be accommodated in the slide rail 122, and when the folding member is in the unfolded position, the first folding part can be arched outward and protrude from the outside of the slide rail 122. One end of the second folding portion 133 away from the first folding portion 132 can be fixed to the slider 122. When the folding member 130 is in the folded position, the second folding portion 133 can be accommodated in the slide rail 122. When the folding member 130 is in the unfolded position, the second folding portion 133 can be arched outward and protrude outside the slide rail 122.

[0037] like Figure 3 As shown, in some embodiments, the slide rail 122 has a first receiving groove 122a, and the first stopper 140 is disposed in the first receiving groove 122a. By arranging the receiving groove on the slide rail 122, the first stopper 140 can be limited, and the slide rail 122 and the first stopper 140 are more compact after being combined, and the occupied volume is small. Optionally, the number of the first receiving grooves 122a corresponds to the number of the sub-stoppers 141. Optionally, the size of the first receiving groove 122a is adapted to the size of the sub-stopper 141, and after the sub-stopper 141 is disposed in the first receiving groove 122a, the sub-stopper 141 is flush with the notch of the first receiving groove 122a.

[0038] The guide member 120 further includes an isolation sheet 123, which is covered in the first receiving groove 122a, thereby enclosing the first stopper 140 in the slide rail 122 to prevent the first stopper 140 from falling off. At the same time, the guide member 120 can also play a role in supporting the sliding portion 131, and the sliding portion 131 can slide on the guide member 120, thereby preventing the first receiving groove 122a or the first stopper 140 from causing the sliding portion 131 to slide and become stuck.

[0039] like Figure 3 , Figure 8-10 As shown, in some embodiments, the guide member 120 has a guide groove 120a, the sliding portion 131 includes a sliding member 1311 and a covering member 1312, the sliding member 1311 is slidably disposed in the guide groove 120a, and the sliding member 1311 can be a hard plastic sheet, such as polyformaldehyde, so that it has good self-lubrication and has less resistance to sliding on the slide rail 122.

[0040] The covering member 1312 is connected to the sliding member 1311, and the covering member 1312 has a second receiving groove 131a, or the covering member 1312 and the sliding member 1311 are enclosed to form a second receiving groove 131a, and the second stopper 150 is arranged in the second receiving groove 131a. The covering member 1312 can protect the second stopper 150, and the covering member 1312 can be made of sheet material, leather and the like. Since the texture of the covering member 1312 is usually soft, the second stopper 150 can serve as the skeleton of the covering member 1312, thereby playing a role in supporting the covering member 1312. It can be understood that the surface of the first folding portion 132 and the second folding portion 133 can also be the covering member 1312, and the filling member 1331 can be arranged inside the first folding portion 132 and the second folding portion 133, thereby supporting the first folding portion 132 and the second folding portion 133.

[0041] like Figure 4-5 As shown, in some embodiments, the folding member 130 is integrally provided, and a first bending portion 134 is provided between the sliding portion 131 and the first folding portion 132, and the sliding portion 131 and the first folding portion 132 rotate through the first bending portion 134. A second bending portion 135 is provided between the first folding portion 132 and the second folding portion 133, and the first folding portion 132 and the second folding portion 133 rotate through the second bending portion 135. A third bending portion 136 is provided between the second folding portion 133 and the guide member 120, and the second folding portion 133 and the guide member 120 rotate through the third bending portion 136. Folds may be provided on the first bending portion 134, the second bending portion 135, and the third bending portion 136 to guide the folding position. Exemplarily, the first bending portion 134, the second bending portion 135 and the third bending portion 136 are made of a flexible material that is easy to bend. For example, the first bending portion 134, the second bending portion 135 and the third bending portion 136 can be part of the covering member 1312, so that the manufacturing difficulty of the folding member 130 is relatively small and the cost is relatively low.

[0042] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, it is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
