[0030] Such as Figure 1 And Figure 2As shown in the figure, a support frame 1 provided by an embodiment of the present utility model is used to provide a support function so as to support the connected object (such as a portable device like a power bank body, a mobile phone, or a tablet) in a required state. The support frame 1 includes a frame body 11 and a foldable support member 12. The frame body 11 is used to connect with the object to be supported, and the connection method can be realized by magnetic attraction, bonding, suction, snap connection, etc., so that the support frame 1 can be connected with different objects to be supported according to the use requirements, with convenient connection and beneficial to improving the application range. Of course, it can also be that the frame body 11 and the object to be supported are integrally formed, and at this time, the support member 12 is directly connected to the object to be supported. The support member 12 has a support state and a storage state. Specifically, the support member 12 has a connection portion 121 and a positioning portion 122. The connection portion 121 of the support member 12 is connected to the frame body 11, and the positioning portion 122 of the support member 12 swings relative to the connection portion 121 of the support member 12, so as to realize the on-demand switching between the support state and the storage state by the movement of the positioning portion 122 relative to the support portion. In the support state, by folding the positioning portion 122, the positioning portion 122 is clamped at the corresponding positions of the frame body 11 and / or the object to be supported, and a support angle is formed under the cooperation of the connection portion 121, so that the entire support member 12 realizes the support function and the position of the frame body 11 can be maintained at the required position; while in the storage state, by folding the positioning portion 122, the positioning portion 122 and the connection portion 121 can be fully unfolded and be flush with the frame body 11 to be in the storage state. In this state, the support member 12 does not occupy extra position space and is convenient to carry.

[0031] As Figure 1 and Figure 2 shown in the figure, in the embodiment of the present utility model, in order to enable the support member 12 to have different support angles and meet the use requirements of different support positions, a plurality of positioning grooves 2 are provided on one side of the frame body 11 and / or the object to be supported facing the support member 12, and the positioning grooves 2 are arranged at intervals. The positioning end of the support member 12 cooperates with the corresponding positioning groove 2 to switch the support of the object to be supported at different support angles. Specifically, as Figure 1 shown in the figure, the positioning groove 2 is directly opened on the frame body 11. As Figure 2As shown, it means that the positioning groove 2 is formed on the object to be supported. Each of the provided positioning grooves 2 can cooperate with the positioning portion 122 respectively, so that the positioning portion 122 can be snapped into the positioning groove 2 to achieve the limitation of the support position. The frame body 11 and the object to be supported have dimensions in different directions of length, width and height. Taking the direction where the height is located (the largest dimension) as the vertical use reference, the positioning grooves 2 are distributed at intervals in the height direction. In this way, when the positioning portion 122 cooperates with the positioning groove 2 at a lower position, the supported inclination is larger (the inclined plane is steeper). And when the positioning portion 122 cooperates with the positioning groove 2 at a higher position, the supported inclination is smaller (the inclined plane is flatter). In this way, by providing the positioning grooves 2 at different heights and then positioning the positioning portion 122 in cooperation with different positioning grooves 2, the selection of different inclination angles can be realized. For example, support angles of 45° or 55° can be provided, which are more in line with the conventional use habits at these angles, and the design is ingenious.

[0032] The support frame 1 provided by the embodiment of the present invention includes a frame body 11 and a foldable support member 12. The support member 12 includes a connecting portion 121 and a positioning portion 122. The connecting portion 121 is connected to the frame body 11, and the positioning portion 122 can swing relative to the connecting portion 121 of the support member 12, so that the support frame 1 has a support state and a storage state. By providing a plurality of positioning grooves 2 on one side of the frame body 11 and / or the object to be supported facing the support member 12, the positioning grooves 2 are arranged at intervals. In this way, in the support state, the fixation of the support position can be achieved by making the positioning end cooperate with the positioning groove 2, and by adjusting the cooperation of the positioning end with the positioning grooves 2 at different positions, the support angle can be adjusted, and the object to be supported can be supported at different support angles to meet the use requirements of different support positions. And in the storage state, the support member 12 is neatly stored without additionally increasing the overall volume, so the portability is good. The support frame 1 has an ingenious design, a simple overall structure, and good operation and use convenience, and preferably meets the actual use requirements.

[0033] In some embodiments, such as Figure 1 and Figure 2As shown, the support member 12 includes a first support body 123 and a second support body 124. The first end of the first support body 123 forms a connection portion 121 and has a first folding line 125. The second end of the first support body 123 is rotatably connected to the first end of the second support body 124, and there is a second folding line 126 therebetween. The second end of the second support body 124 forms a positioning portion 122. Specifically, the first support body 123 and the second support body 124 are plate-like members with substantially the same shape, and both have opposite first ends and second ends. The first end of the first support body 123 forms a connection portion 121 and has a first folding line 125. In this way, it is fixed to the frame body 11 through the connection portion 121, and the rest of the first support body 123 can swing around the first folding line 125 to realize the adjustment of the support position. The first end of the second support body 124 is connected to the second end of the first support body 123 and has a second folding line 126. In this way, the whole second support body 124 can swing around the second folding line 126, and the second end of the second support body 124 is a free end. A positioning portion 122 is formed at this second end, and the support position can be adjusted around the second folding line 126. Specifically, referring to Figure 4 and Figure 5 As shown, in the support state, the second support body 124 bends relative to the first support body 123 around the second folding line 126, so that the positioning portion 122 can be snapped into the corresponding positioning groove 2 as required. At the same time, the overall support function is realized by the partial abutment of the first support member 12 on the support surface (such as a desktop). In the storage state, the first support body 123 and the second support body 124 are unfolded and located in the same plane. The first support body 123 and the second support body 124 form a plane as a whole and fit on the surface of the support object, without increasing the overall volume additionally, with a beautiful overall appearance and being convenient to carry.

[0034] In some embodiments, such as Figure 1 and Figure 2As shown in the figure, an installation part 111 is provided on one side of the frame body 11 facing the support part 12, and the connection part 121 of the support part 12 is fixed on the installation part 111. Moreover, in the first direction, the first folding line 125 is located above the bottom edge of the installation part 111. Specifically, the frame body 11 is usually a frame structure with a hollow middle part to be able to accommodate the object to be supported. In this embodiment, along the first direction of the frame body 11 (i.e., the height direction of the frame body 11), an installation part 111 is provided at the bottom position of the frame body 11. The installation part 111 extends in the height direction and has a suitable size, so that the formed installation part 111 has a certain solid area for the installation and fixation of the connection part 121. After the connection part 121 is fixed on the installation part 111, the first folding line 125 is located above the bottom edge of the installation part 111. In this way, when the rest of the first support body 123 is folded around the first folding line 125 and abuts against the support surface, it is in an inclined state with the support surface, so that the contact area with the support surface can be reduced, the friction can be reduced, the first support body 123 is not easily worn, and the service life is improved.

[0035] In some embodiments, as Figure 1 and Figure 2 shown, a positioning groove 2 is provided on the frame body 11. A first attracting member 112 is provided adjacent to the positioning groove 2 on the frame body 11, and a second attracting member 127 is provided on the positioning portion 122. Among them, the first attracting member 112 and the second attracting member 127 attract each other to attract the positioning portion 122 to automatically snap into the corresponding positioning groove 2. With such a setting, when operating the cooperation and positioning of the positioning portion 122 and the positioning groove 2, through the mutual attraction between the first attracting member 112 and the second attracting member 127, during the process of moving the positioning portion 122 close to the positioning groove 2, the first attracting member 112 and the second attracting member 127 attract each other, which will guide the positioning portion 122 to automatically find the position of the positioning groove 2 and guide the positioning portion 122 to automatically snap into the positioning groove 2, so as to reliably achieve positioning. Optionally, both the first attracting member 112 and the second attracting member 127 are set as magnets, or any one of them is a magnet and the other is a metal member that can be magnetically attracted, such as an iron sheet, etc. Optionally, the first attracting member 112 can be provided at at least one of the three positions: on the opposite sides or one side of the positioning groove 2 or at the bottom of the positioning groove 2; and the second attracting member 127 can be provided at the part of the positioning portion 122 that first snaps into the positioning groove 2. Of course, it can be understood that the first attracting member 112 and the second attracting member 127 can also be provided at other positions to be able to attract each other and achieve reliable connection.

[0036] In some embodiments, as Figure 1As shown, a receiving groove 113 is provided on the frame body 11, and each positioning groove 2 is arranged at the bottom of the receiving groove 113; wherein, in the storage state, both the first support body 123 and the second support body 124 are located within the receiving groove 113. Specifically, the depth of the receiving groove 113 is substantially equal to the thickness of the first support body 123 or the second support body 124. In this way, the first support body 123 and the second support body 124 can be bent and stored within the receiving groove 113 in the storage state without protruding, improving the overall aesthetics of the support frame 1.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame 1 further includes a holding block 13. The holding block 13 is arranged on the second support body 124, and can be integrally formed with the second support body 124 or an independent part and connected to the second support body 124. The holding block 13 is used to operate the folding of the second support body 124, that is, when it is necessary to operate the second support body 124, by grasping the holding block 13, the second support body 124 can be driven to perform a synchronous folding movement to achieve the corresponding operation. For example, when the second support body 124 is in the storage state and located within the receiving groove 113, at this time, by grasping the holding block 13, the second support body 124 can be folded out of the receiving groove 113, improving the convenience of operation.

[0038] Such as Figure 2 As shown, in the embodiment of the present utility model, the holding block 13 is convexly arranged on the side of the second support body 124 and set to be equal in thickness to the second support body 124, and a notch 114 is correspondingly arranged on the frame body 11. In the storage state, the holding block 13 is located within the notch 114. With such a setting, the thickness of the holding block 13 is equal to the thickness of the second support body 124, making the overall shape flat and having good aesthetics. Moreover, by providing the notch 114 to accommodate the holding block 13, it not only does not affect the stability of the overall placement due to local unevenness, but also improves the convenience of operating the holding block 13.

[0039] In some embodiments, such as Figure 1 As shown, at least a third attracting member 115 can also be provided at the position of the frame body 11 corresponding to the second support body 124 in the storage state. The third attracting member 115 and the second attracting member 127 attract each other to position the second support body 124. Specifically, the third attracting member 115 is also one of a magnet or a metal member that can cooperate with the second attracting member 127 to attract each other, and is arranged at least at the position corresponding to the second support body 124 in the storage state. Thus, under the attracting force of the mutual attraction between the second attracting member 127 and the third attracting member 115, the position of the second support body 124 in the storage state can be kept stable without loosening randomly.

[0040] Such asFigures 3 to 5 As shown in the figure, in the embodiment of the present utility model, a multifunctional mobile power supply 3 is further provided, which includes a power supply body 31, a charging connector 32, a bottom case 33, and the support frame 1 described in any of the above embodiments. At least a battery cell for storing electric energy and a charging component for charging external devices are provided inside the power supply body 31; the charging connector 32 is used for connecting to an external power supply to charge the battery cell, the charging connector 32 is installed on the power supply body 31 and is electrically connected to the battery cell; the bottom case 33 is connected to the power supply body 31, and a receiving cavity is formed between the bottom case 33 and the power supply body 31, and the battery cell and the charging component are installed in the receiving cavity. With such a setting, the electric energy stored in the battery cell can be consumed through the charging component to supply power to the external device to be charged, and the external charging method can be wired charging or wireless charging. The external electric energy can be connected through the charging connector 32 to charge the battery cell, so that the battery cell can obtain electric energy for charging other devices. By connecting the frame body 11 to the bottom case 33, or the bottom case 33 and the frame body 11 are integrally formed. Thus, under the supporting action provided by the support frame 1, the power supply body 31 can be supported, and further, the device to be charged placed on the power supply body 31 can be supported, so that it is not necessary to hold it by hand all the time, especially in the state of charging and using at the same time, which liberates both hands and improves the convenience of use.

[0041] Optionally, as Figure 3 shown, the support frame 1 connected to the bottom case 33 is in a retracted state. At this time, the support frame 1 is flush with the surface of the bottom case 33, without increasing the volume additionally, and the overall aesthetics is good. As Figure 4 and Figure 5 shown, the support frame 1 is in the first support state and the second support state respectively. At this time, the provided support angles are different, so that the use requirements with different support angle requirements can be met, and the use flexibility is good.

[0042] Specifically, the frame body 11 can be connected to the power supply body 31 as a whole by means of bonding, suction, magnetic attraction, snap connection, etc. In this way, the support frame 1 can be connected to different bottom cases 33, and can be disassembled when not needed, with a wide application range and flexible use methods. It can also be that the frame body 11 and the bottom case 33 are integrally formed, that is, the entire support frame 1 is a part of the overall structure of the multifunctional mobile power supply 3. In this way, the connection stability is good. Moreover, in both of the above two ways, the positioning groove 2 can be opened on the frame body 11 and / or the bottom case 33, so as to cooperate with the positioning portion 122 to realize the positioning of the support position and the adjustment of the support angle.

[0043] In some embodiments, the charging component includes a wireless charging controller and a charging coil. The wireless charging controller is connected to the battery cell to control the discharge of the battery cell. The charging coil is connected to the wireless charging controller. The charging coil is used to transmit electrical energy through electromagnetic induction and charge an external device to be charged. With such an arrangement, the multifunctional mobile power supply 3 can achieve the function of wireless charging. Specifically, the wireless charging controller can be a combination of electronic components such as a current board and a processing chip with logical control functions. The charging coil is an important component for realizing wireless charging. Using the principle of electromagnetic induction, an induced electromotive force and an induced current are generated when the ambient electromagnetic field changes. As long as a structure such as a power supply coil adapted to the charging coil is provided on the corresponding charging device and under the corresponding control of the wireless charging controller, wireless charging can be achieved, and the charging operation is more convenient and the use is more convenient.

[0044] The foregoing are only the preferred embodiments of the present invention and are not intended to limit the present invention.
