Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, and particularly relates to a mobile power supply. Background Art

[0002] With the popularization of mobile devices and the increasing demand for battery life, portable micro mobile power supplies have gradually become essential accessories for users' daily travel due to their small size, light weight, and easy portability.

[0003] For existing portable micro mobile power supplies, due to the design requirements of their small size, the USB interfaces are often directly set on the surface of the mobile power supply housing without additional protection structures. Since the USB interfaces are directly exposed, they are easily affected by external force extrusion, friction, or improper plugging and unplugging, resulting in interface deformation, loosening, or even damage. Summary of the Utility Model

[0004] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this purpose, the utility model provides a mobile power supply, which has the advantages of reducing interface damage and improving the service life of the product.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

The transmission plate passes through the positioning hole and is inserted into the connecting groove.

[0016] Optionally, the transmission assembly further includes at least one elastic member connected between the top plate and the connecting plate; when pressing the push block along the opening direction of the mounting hole, the elastic member can be compressed so that the connecting plate moves away from the mounting hole to drive the limiting protrusion out of the first limiting groove.

[0034] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Based on the embodiments in the implementation manners, it is intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0035] The phrase "in one embodiment" as cited in this specification means that the specific features, structures, or characteristics described in connection with the embodiment itself can be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" at various positions in the specification does not necessarily refer to the same embodiment.

[0036] This embodiment provides a mobile power supply, as shown in Figure 1 and Figure 2As shown, it includes a mobile power main body 40, a shell 10 and a USB interface 30. The mobile power main body 40 is arranged in the inner cavity 10a of the shell 10. A receiving hole 10b is formed on the surface of the shell 10. The receiving hole 10b is connected to the inner cavity 10a of the shell 10. The USB interface 30 is electrically connected to the mobile power main body 40, and the USB interface 30 can extend into the receiving hole 10b.

[0037] The mobile power source further includes a transmission assembly 20 , and the transmission assembly 20 is connected to the USB interface 30 .

[0038] The USB interface 30 has a storage position and a charging position. When the USB interface 30 is in the charging position, the output end 31 of the USB interface 30 extends out of the receiving hole 10b. When the USB interface 30 is in the storage position, the output end 31 of the USB interface 30 is located in the receiving hole 10b.

[0039] The transmission assembly 20 can drive the USB interface 30 to move back and forth between the storage position and the charging position, and when the USB interface 30 is located at the storage position, the transmission assembly 20 is fixedly connected to the housing 10 .

[0040] By setting the transmission assembly 20, when it is necessary to charge the device to be charged, the transmission assembly 20 is pushed to drive the USB interface 30 to move to the charging position, so that the output end 31 of the USB interface 30 extends out of the receiving hole 10b and can be inserted into the charging port of the device to be charged. When the mobile power supply is not needed, the transmission assembly 20 is pushed to drive the USB interface 30 to move to the storage position to prevent the USB interface 30 from being exposed from the receiving hole 10b, thereby preventing the USB interface 30 from being squeezed when the mobile power supply is stored, or the mobile power supply is dropped, etc., which causes damage to the USB interface 30, thereby improving the service life of the product. In addition, the USB interface 30 of this embodiment will not protrude from the surface of the housing 10 when it is in the storage position, thereby facilitating storage, reducing the storage space, and improving the aesthetics.

[0041] Alternatively, if Figures 2 to 8 As shown, the transmission assembly 20 includes a push block 21, a connecting plate 22 and a transmission plate 23. The connecting plate 22 is arranged between the mobile power supply body 40 and the inner wall of the shell 10. The push block 21 is arranged on the side of the connecting plate 22 away from the mobile power supply body 40. The transmission plate 23 is arranged on the side of the connecting plate 22 facing the mobile power supply body 40, and the transmission plate 23 is connected to the USB interface 30.

[0042] The housing 10 is formed with a mounting hole 10c, which is communicated with the inner cavity 10a of the housing 10. The opening direction of the mounting hole 10c intersects with the opening direction of the accommodating hole 10b, and the push block 21 extends into the mounting hole 10c.

[0043] A first limiting groove 22a is formed on the surface of the connecting plate 22. The first limiting groove 22a is on the same side as the pushing block 21. A limiting protrusion 11 is formed on one side of the housing 10 facing the connecting plate 22. When the USB interface 30 is in the storage position, the pushing block 21 contacts the side wall of the mounting hole 10c away from the accommodating hole 10b. The connecting plate 22 fits against the inner wall of the housing 10, and the limiting protrusion 11 can be inserted into the first limiting groove 22a so that the connecting plate 22 and the housing 10 are relatively fixed.

[0044] Through the cooperation of the pushing block 21, the connecting plate 22, the transmission plate 23 and the USB interface 30, when the pushing block 21 is pushed, the USB interface 30 can be driven by the transmission plate 23 to move along the moving direction of the pushing block 21, so as to realize the reciprocating movement of the USB interface 30 between the charging position and the storage position. Moreover, by providing the limiting protrusion 11 on the inner wall of the housing 10, when the USB interface 30 is in the storage position, the limiting protrusion 11 can be inserted into the first limiting groove 22a, thereby restricting the movement of the connecting plate 22 between the storage position and the charging position and forming relative fixation with the housing 10. Preferably, when the limiting protrusion 11 is inserted into the first limiting groove 22a, the side wall of the limiting protrusion 11 contacts the side wall of the first limiting groove 22a, so as to ensure that the connecting plate 22 does not shake. When the mobile power supply is not in use, the USB interface 30 is stored in the housing 10 to avoid damage to the USB interface 30.

[0045] In this embodiment, no special limitation is imposed on the specific implementation manner of the cooperation between the limiting protrusion 11 and the first limiting groove 22a. For example, the limiting protrusion 11 has a certain elasticity. When the pushing block 21 is pushed, under the extrusion of the first limiting groove 22a, the limiting protrusion 11 can be deformed to a certain extent and thus move out of the first limiting groove 22a.

[0046] In an alternative embodiment, as Figure 3 and Figure 4 shown, the mobile power supply further includes a mounting bracket. The mounting bracket includes a top plate 51 and two side plates (not shown in the figure). The top plate 51 is connected between the two side plates. Both side plates are connected to the inner wall of the housing 10. The top plate 51 is arranged on the mobile power supply main body 40, and the connecting plate 22 is arranged between the top plate 51 and the inner wall of the housing 10.

[0047] The top plate 51 is formed with a positioning hole penetrating through the top plate 51 in the thickness direction. The USB interface 30 is formed with a connecting groove 30a. The opening direction of the positioning hole is the same as the opening direction of the connecting groove 30a. The transmission plate 23 passes through the positioning hole and the transmission plate 23 is inserted into the connecting groove 30a.

[0048] By setting up the mounting bracket, connecting the mounting bracket to the housing 10, and arranging the transmission component 20 on the mounting bracket, the complex overall structure is decomposed into simpler parts for mold development, reducing the production design difficulty and saving the production cost. Each part can be produced independently and in parallel, improving the production efficiency. When a failure occurs, it is also easier to locate and replace the damaged parts, saving the maintenance cost.

[0049] Optionally, as Figure 3 shown, the transmission component 20 further includes at least one elastic member, and the elastic member is connected between the top plate 51 and the connecting plate 22. When pressing the push block 21 along the opening direction of the mounting hole 10c, the elastic member can be compressed so that the connecting plate 22 moves away from the mounting hole 10c to drive the limit protrusion 11 out of the first limit groove 22a.

[0050] Through the cooperation of the elastic member and the connecting plate 22, when the push block 21 is released, the limit protrusion 11 is inserted into the first limit groove 22a under the reset action of the elastic member, realizing the automatic locking of the USB interface 30 in the storage position.

[0051] In the present utility model, no special limitation is imposed on the specific structure of the elastic member. In an optional implementation manner, the elastic member includes a fixing portion 241 and two elastic portions 242, and the fixing portion 241 is arranged on the mobile power supply main body 40. One end of the elastic portion 242 is connected to the fixing portion 241, and the other end of the elastic portion 242 abuts against the connecting plate 22.

[0052] Wherein, the elastic portion 242 plays a supporting role for the connecting plate 22, and when pressing the push block 21, the elastic portion 242 can be deformed so that the connecting plate 22 can move along the pressing direction. When the push block 21 is released, the elastic portion 242 can be reset to drive the connecting plate 22 to move towards the mounting hole 10c.

[0053] Optionally, as Figure 5 and Figure 6 shown, when the USB interface 30 is in the storage position, the top of the push block 21 protrudes from the outer surface of the housing 10.

[0054] Setting the top of the push block 21 to protrude from the surface of the housing 10 facilitates the operation of the push block 21.

[0055] In an optional implementation manner, as Figures 5 to 7 shown, there are two limit protrusions 11, and a second limit groove 10d is formed between the two limit protrusions 11. The connecting plate 22 is formed with a limit portion 221, and the limit portion 221 is adjacent to the first limit groove 22a. When the USB interface 30 is in the charging position, the limit portion 221 can extend into the second limit groove 10d so that the connecting plate 22 is relatively fixed to the housing 10.

[0056] By providing two limiting protrusions 11, when the USB interface 30 is pushed to the charging position, the limiting portion 221 can be inserted into the second limiting groove 10d formed between the two limiting protrusions 11, thereby restricting the movement of the connecting plate 22 between the charging position and the storage position, and forming a relative fixation with the housing 10. In this way, when the output end 31 of the USB interface 30 is inserted into the charging port of the device to be charged, it is not necessary for the user to continuously press the push block 21 to ensure that the output end 31 of the USB interface 30 is continuously exposed.

[0057] In a specific embodiment, the initial state of the mobile power USB interface 30 is the storage state. When it is necessary to move out the output end 31 of the USB interface 30, the user first presses the push block 21, and the elastic member is compressed, so that the limiting protrusion 11 is removed from the first limiting groove 22a, releasing the limiting effect on the connecting plate 22. Then, the push block 21 is pushed in the direction from the storage position to the charging position until the push block 21 abuts against one end of the mounting hole 10c, that is, the USB interface 30 is in the charging position. At this time, the user releases the push block 21, and the elastic member resets, driving the connecting plate 22 to move in a direction away from the mobile power main body 40 until the limiting portion 221 is inserted into the second limiting groove 10d.

[0058] Optionally, as Figure 1 shown, in the width direction of the mounting hole 10c, the size of the mounting hole 10c is the same as that of the push block 21. The width direction of the mounting hole 10c intersects with the moving direction of the push block 21.

[0059] By restricting the size of the mounting hole 10c to be the same as that of the push block 21, during the process of pushing the push block 21, the side wall of the push block 21 fits with the mounting hole 10c, so that the mounting hole 10c plays a guiding role for the push block 21, ensuring the stable movement of the push block 21.

[0060] In an alternative embodiment, when the USB interface 30 is in the charging position and when the USB interface 30 is in the charging position, the connecting plate 22 can cover the connection between the mounting hole 10c and the inner cavity 10a of the housing 10.

[0061] That is to say, in the width direction of the mounting hole 10c, the size of the connecting plate 22 is larger than that of the mounting hole 10c, thereby preventing debris from entering the inner cavity 10a of the housing 10 through the mounting hole 10c, and improving the protection of the internal components of the mobile power.

[0062] Optionally, the push block 21 includes a push block 21 main body and anti-slip lines (not shown in the figure). The push block 21 main body is arranged on the connecting plate 22, and the anti-slip lines are arranged on the top of the push block 21 main body.

[0063] By setting anti-slip lines, the frictional force between the user and the push block 21 is increased, facilitating the user to push the push block 21 and preventing the user's hand from slipping, which may cause the inability to remove the output end 31 of the USB interface 30, thus improving the user experience.

[0064] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
