[0045] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described ones are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0047] In addition, it should be noted that the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0048] In the prior art, the power supply housing of a mobile power supply and the charging connector adopt a fixed structure, and there is no relative movement between the two; thus, the charging connector needs to always protrude outside the power supply housing so that it can be plugged into an electronic device for charging operations; however, the externally protruding charging connector is easily deformed and damaged due to being impacted by the outside world, and further causes the inability to perform charging operations on the electronic device.

[0049] To solve the above technical problems, the present utility model proposes a mobile power supply.

[0050] Please refer to Figures 1-4 , in an embodiment of the present utility model, the mobile power supply includes:

[0051] A power supply housing 1, inside which a battery assembly 2 is arranged; on the outside of the power supply housing 1, there is a first receiving cavity 103 arranged in a concave shape;

[0052] A charging member 3, at the first end of the charging member 3, there is a charging connector 301, and the second end of the charging member 3 is rotatably connected to the power supply housing 1 so that the charging member 3 can rotate relative to the power supply housing 1 to a first angle and a second angle; when the charging member 3 is at the first angle, as shown in the attached Figure 4 drawings, the charging connector 301 is located outside the power supply housing 1 so that the charging connector 301 can be plugged into an external electronic device; when the charging member 3 is at the second angle, as shown in the attached Figures 1-2 drawings, the charging connector 301 is received in the first receiving cavity 103;

[0053] The elastic sheet structure 4 is disposed inside the power supply housing 1, and the elastic sheet structure 4 is connected to the second end of the charging member 3; the elastic sheet structure 4 is configured to apply a second force in the direction of the second angle to the charging member 3 when the charging member 3 rotates from the first angle to the second angle; and the elastic sheet structure 4 is configured to apply a first force in the direction of the first angle to the charging member 3 when the charging member 3 rotates from the second angle to the first angle.

[0054] The technical solution of the present utility model is that a first receiving cavity 103 which is recessed is provided outside the power supply housing 1, and the charging member 3 equipped with the charging connector 301 is rotatably connected to the power supply housing 1, so that the charging member 3 can rotate relative to the power supply housing 1 to the first angle and the second angle; wherein, when the charging member 3 is at the first angle, the charging connector 301 is located outside the power supply housing 1, so that the charging connector 301 can be plugged into an external electronic device to charge the electronic device; when the charging member 3 is at the second angle, the charging connector 301 is received in the first receiving cavity 103, so as to realize that the charging connector 301 can be received inside the power supply housing 1 in a non-charging state, reducing the probability of its deformation and damage due to external impact.

[0055] Moreover, the present utility model further provides an elastic sheet structure 4. When the charging member 3 rotates from the first angle to the second angle, the elastic sheet structure 4 is used to apply a second force in the direction of the second angle to the charging member 3; and when the charging member 3 rotates from the second angle to the first angle, the elastic sheet structure 4 is used to apply a first force in the direction of the first angle to the charging member 3; in this way, the user only needs to apply a weak initial driving force to the charging member 3, and then the charging member 3 can realize the mutual rotation between the first angle and the second angle by relying on the first force or the second force applied by the elastic sheet structure 4, and the charging member 3 can be driven to rotate without the user consuming a lot of physical strength, thereby effectively improving the user experience.

[0056] Wherein, the models of the charging connector 301 include but are not limited to one or more of Lightning interface, Mini USB interface, Micro USB interface and Type-C interface. With such a setting, by adopting charging connectors 301 of multiple models, it is convenient for the user to charge the mobile power supply with a suitable charging connector 301 according to the specific situation.

[0057] Specifically, refer to the appendix Figure 3 and the appendix Figures 5-7, the charging member 3 includes two sets of transmission structures 5, and the two sets of transmission structures 5 are symmetrically arranged on opposite sides of the second end of the charging member 3; each set of transmission structure includes a rotating shaft portion 6 and an eccentric wheel portion 7, and the eccentric wheel portion 7 is installed at one end of the rotating shaft portion 6 away from the charging member 3; a through hole portion 104 is provided on the side of the first accommodation cavity 103, and the rotating shaft portion 6 is rotatably connected in the through hole portion 104; the cross-sectional area of the eccentric wheel portion 7 is larger than the hole area of the through hole portion 104. With such a setting, the rotating shaft portion 6 with a circular cross-sectional shape is rotatably connected in the through hole portion 104 to enable the charging member 3 to rotate relative to the power supply housing 1 around its second end. And, since the cross-sectional area of the eccentric wheel portion 7 is larger than the hole area of the through hole portion 104, at this time, the connecting members (the charging member 3 and the eccentric wheel portion 7) on both sides of the rotating shaft portion 6 cannot pass through the through hole portion 104, so as to ensure that the rotating shaft portion 6 and the through hole portion 104 cannot be disengaged, so that the charging member 3 can always be connected to the power supply housing 1 while rotating relative to the power supply housing.

[0058] Further, referring to the attached Figure 7 , a hollow structure (not shown in the drawings) is provided through the inside of the rotating shaft portion 6 and the eccentric wheel portion 7, and the hollow structure is used for the power connection line 8 to pass through, so that the charging connector 301 and the battery assembly 2 can be electrically connected to each other through the power connection line 8. With such a setting, since the movement amplitude of the rotating shaft portion 6 and the eccentric wheel portion 7 of the charging member 3 is small (only rotational movement) when the charging member 3 rotates, the power connection line 8 is passed through the hollow structure inside the rotating shaft portion 6 and the eccentric wheel portion 7 to electrically connect the charging connector 301 and the battery assembly 2, which can minimize the pulling amplitude range of the power connection line 8 during the rotation of the charging member 3, thereby avoiding damage to the power connection line 8 due to excessive pulling.

[0059] Among them, there are many specific structures of the above-mentioned elastic sheet mechanism. In this embodiment, referring to the attached Figures 5-10 , the elastic sheet structure 4 includes an elastic sheet member 401, and an elastic sheet fixing portion 9 is provided inside the power supply housing 1; the first end of the elastic sheet member 401 is fixedly connected to the elastic sheet fixing portion 9; the side portion of the eccentric wheel portion 7 includes a first contact surface 701 and a second contact surface 702. When the charging member 3 is at the first angle, the second end of the elastic sheet member 401 is in contact and connected with the first contact surface 701; when the charging member 3 is at the second angle, the second end of the elastic sheet member 401 is in contact and connected with the second contact surface 702; an outwardly convex arc portion 703 is further provided on the side portion of the eccentric wheel portion 7, and the arc portion 703 is provided between the first contact surface 701 and the second contact surface 702; when the charging member 3 rotates between the first angle and the second angle, the arc portion 703 presses the second end of the elastic sheet member 401, so that the second end of the elastic sheet member 401 exerts an elastic force on the arc portion 703.

[0060] With such a setting, when the charging member 3 rotates from the first angle to the second angle, referring to the attached Figure 9 Analyzing, when the initial rotational force applied by the user to the charging member 3 can cause the arc portion 703 to press the elastic piece 401, at this time, the initial rotational force is directed towards the second angle direction, and the elastic piece 401 applies an elastic force towards the eccentric wheel portion 7 to the eccentric wheel portion 7. At this time, the charging member rotates towards the second angle direction along with the combined force (the second force) of the initial rotational force and the elastic force until the second contact surface 702 of the eccentric wheel portion 7 fits with the second end of the elastic piece 401.

[0061] Similarly, when the charging member 3 rotates from the second angle to the first angle, referring to the attached Figure 10 Analyzing, when the initial rotational force applied by the user to the charging member 3 can cause the arc portion 703 to press the elastic piece 401, at this time, the initial rotational force is directed towards the first angle direction, and the elastic piece 401 applies an elastic force towards the eccentric wheel portion 7 to the eccentric wheel portion 7. At this time, the charging member rotates towards the first angle direction along with the combined force (the first force) of the initial rotational force and the elastic force until the first contact surface 701 of the eccentric wheel portion 7 fits with the second end of the elastic piece 401.

[0062] It can be seen that during the rotation process of the charging member 3 between the first angle and the second angle, the user only needs to apply a weak initial rotational force to the charging member 3, and it is required that the initial rotational force can cause the arc portion 703 to press the elastic piece 401, then the charging member 3 can be mutually rotated between the first angle and the second angle by relying on the elastic piece structure 4, so as to ensure the smooth implementation of the technical solution of this application. At the same time, when the user does not provide the initial rotational force, the arc portion 703 cannot overcome the elastic force of the elastic piece 401 to press it, so as to ensure that the charging member 3 maintains the state of the first angle or the second angle without external force.

[0063] Furthermore, referring to the attached Figure 8 , the first end of the elastic piece 401 is provided with a mounting hole 402, and the elastic piece fixing portion 9 is provided with a threaded hole (not shown in the attached drawings); the mobile power supply further includes a fixing bolt (not shown in the attached drawings), and the fixing bolt can pass through the mounting hole 402 and be threadedly connected with the threaded hole to fix the elastic piece 401 and the elastic piece fixing portion 9 to each other. With such a setting, the elastic piece 401 and the elastic piece fixing portion 9 are fixed to each other by the fixing bolt, and the structure is simple and practical.

[0064] Furthermore, referring to the attached Figure 6, the first end of the elastic piece 401 winds around the end of the elastic piece fixing part 9; arranged in this way, the contact area between the elastic piece 401 and the elastic piece fixing part 9 is increased as much as possible, thereby improving the connection strength between the first end of the elastic piece 401 and the elastic piece fixing part 9; in this way, when the second end of the elastic piece 401 bears the pressing of the arc part 703, the first end of the elastic piece 401 can still maintain a tight connection with the elastic piece fixing part 9 and will not shake.

[0065] Further, referring to the appendix Figure 6 , limiting baffles 902 are provided on opposite sides of the elastic piece fixing part 9, and the limiting baffles 902 are used to abut against the side of the elastic piece 401; arranged in this way, the lateral movement of the elastic piece 401 is restricted by the limiting baffles 902, thereby reducing the probability of lateral shaking of the elastic piece 401.

[0066] In other embodiments, referring to the appendix Figure 6 , a positioning post 903 is provided in the middle of the elastic piece fixing part 9, and a positioning hole 403 inserted and matched with the positioning post 903 is provided in the middle of the elastic piece 401. Arranged in this way, before installing the elastic piece 401 and the elastic piece fixing part 9 with a fixing bolt, the positioning hole 403 and the positioning post 903 can be used for mutual fixation first to realize the pre-positioning of the elastic piece 401 and the elastic piece fixing part 9, thereby improving the installation efficiency of the elastic piece 401 and the elastic piece fixing part 9.

[0067] As a preferred solution of the above embodiment, referring to the appendix Figures 1-4 , one side of the first accommodation cavity 103 close to the charging connector 301 adopts an open structure. Arranged in this way, the user can wiggle the charging connector 301 at the first end of the charging member 3 from the open side of the first accommodation cavity 103 so that the charging member 3 can rotate relative to the power supply housing 1 around its second end, and the structure is simple and practical.

[0068] In other embodiments of the present application, referring to the appendix Figures 1-4 , a power transmission interface 11 is provided on the outside of the power supply housing 1, and the power transmission interface 11 is electrically connected to the battery assembly 2. Arranged in this way, the battery assembly 2 is replenished with power through the power transmission interface 11 to ensure that the battery assembly 2 has enough power to charge the electronic device. Among them, the models of the above power transmission interface 11 include but are not limited to one or more of a Mini USB interface, a Micro USB interface, and a Type-C interface. Arranged in this way, multiple models of power transmission interfaces 11 are adopted, which is convenient for the user to replenish the power of the battery assembly 2 with a suitable power transmission interface 11 according to the specific situation.

[0069] In other embodiments of the present application, referring to the appendix Figures 1-4, an external part of the power supply housing 1 is provided with a lanyard part 12 for a cord member (not shown in the drawings) to pass through; with such a setting, by passing the cord member through the lanyard part 12 to make something like a handle cord, the portability of the mobile power supply can be improved.

[0070] In other embodiments of the present application, an external part of the power supply housing 1 is provided with a power indicator 13 and a switch button 14. The power indicator 13 is electrically connected to the battery assembly 2; the switch button 14 is electrically connected to the power indicator 13; with such a setting, the power indicator 13 is manually turned on by using the switch button 14, so that the user can observe the remaining power of the battery assembly 2 through the power indicator 13, and timely replenish the power of the battery assembly 2 to ensure that the mobile power supply can be continuously used.

[0071] Specifically, referring to the attached Figure 11 , the switch button 14 includes a button cap 1401 and a button arm 1402 that can undergo elastic deformation; with such a setting, the user presses the button cap 1401 to trigger the patch button on the circuit board inside the power supply housing 1, thereby realizing the operation and control of the power indicator 13. Subsequently, under the action of the elastic restoring force of the elastically deformable button arm 1402, the button cap 1401 returns to its original position.

[0072] There are many specific structures of the button arm 1402; for example, as shown in Figure a of the attached Figure 11 , the button arm 1402 has a linear structure. One end of the button arm 1402 is fixedly connected to the button cap 1401, and the other end of the button arm 1402 is fixedly connected to the power supply housing 1 through a connecting hole member 16; or, as shown in Figure b of the attached Figure 11 , the button arm 1402 has an arc-shaped structure. The two arc-shaped ends of the button arm 1402 are respectively connected to the opposite ends of the button cap 1401, and the arc-shaped middle part of the button arm 1402 is fixedly connected to the power supply housing 1 through a connecting hole member 16. Among them, when the button arm 1402 has an arc-shaped structure, since the acting force of the button arm 1402 on the button cap 1401 is dispersed to the opposite ends of the button cap 1401, it can ensure that both sides of the button cap 1401 are balanced in force while the button cap 1401 bears the elastic acting force of the button arm 1402, thereby avoiding displacement and deformation of the button cap 1401 caused by repeated pressing, which is beneficial to improving the service life of the switch button 14.

[0073] In other embodiments of the present application, referring to the attached Figure 2 and the attached Figure 4, an external support plate member 15 is provided on the power supply housing 1. One end of the support plate member 15 is rotatably connected to the power supply housing 1, and the other end of the support plate member 15 is used to abut against the horizontal plane, so that a triangular structure is formed among the power supply housing 1, the support plate member 15 and the horizontal plane. At this time, the insertion direction of the charging connector 301 of the charging member 3 at the first angle is parallel to the horizontal plane. With such a setting, considering that general electronic devices are placed horizontally when watching videos, since the insertion direction of the charging connector 301 of the charging member 3 at the first angle is parallel to the horizontal plane at this time, that is to say, the power supply housing 1 is installed on the side of the horizontally placed electronic device. During the charging operation in which the electronic device is plugged into the power supply housing 1 through the charging connector 301, the electronic device and the power supply housing 1 are regarded as a whole. While the support plate member 15 supports the power supply housing 1, it also equivalently supports the electronic device, so that the utility model can act as a bracket, realizing the function of supporting the electronic device, and making it convenient for the user to watch videos while charging the mobile power supply. And, by utilizing the characteristic of the triangular structure having high stability, the power supply housing 1, the support plate member 15 and the horizontal plane are cooperated with each other to form a triangular structure, improving the stability when supporting the electronic device.

[0074] Further, referring to the attached Figure 2 and the attached Figure 4 , a second receiving cavity 105 which is recessed is provided on the outside of the power supply housing 1. The second receiving cavity 105 is located on the rotation path of the support plate member 15, and the second receiving cavity 105 is used to receive the support plate member 15. With such a setting, when there is no need to support the electronic device, the support plate member 15 can be rotated and received in the second receiving cavity 105 to prevent damage to the support plate member 15 caused by external impact.
