[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] For each of the specific technical features described in the specific embodiments, without conflict, they can be combined in any suitable manner. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, various possible combination manners of each specific technical feature in the present utility model will not be described separately.

[0029] In the following description, the terms "first / second / ..." involved are only used to distinguish different objects and do not indicate that there are any same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", and "inside" involved are all orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0030] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the element. "Plural" means greater than or equal to two.

[0031] Such as Figure 1 And Figure 2As shown in the figure, an embodiment of the present utility model provides a mobile power supply, which includes a housing 1, a connector 2, and a support frame 3. Inside the housing 1, at least a battery cell assembly is provided. The battery cell assembly generally includes components such as a battery and a circuit board, and is used to implement basic functions of the mobile power supply such as charging and discharging. The connector 2 is electrically connected to the battery cell assembly and is used to connect to a device that needs to be charged, such as a mobile phone, to implement the power supply function. The support frame 3 is a component for installing the connector 2. The connector 2 is connected to the support frame 3, and the support frame 3 provides support for the installation position of the connector 2. Among them, a first connection structure 4 is provided on the housing 1, and a second connection structure 5 is provided on the support frame 3. The second connection structure 5 is connected to the first connection structure 4 to fix the support frame 3 to the housing 1. In some implementation schemes, such as Figure 1 As shown in the figure, the support frame 3 can be arranged at the middle position outside the housing 1. With such a design, the overall structure is more symmetrical and beautiful, and it has better stability when placed for use. Of course, it can be understood that for the relative position between the support frame 3 and the housing 1, factors such as the user's usage preference and the difficulty of assembly can be comprehensively considered for design, and the embodiments of the present utility model do not make more limitations.

[0032] Optionally, for the specific implementation manner of connecting the connector 2 to the support frame 3, the connector 2 can be directly fixed on the support frame 3, or the connector 2 can be movably connected to the support frame 3. When the connector 2 is directly fixed on the support frame 3, a protective cover can be provided on the connector 2 to cover and protect the connector 2 and improve the aesthetics. When the mobile power supply needs to be used, only the protective cover needs to be opened to expose the connector 2. When the connector 2 is movably connected to the support frame 3, the activity space of the connector 2 can be designed so that the connector 2 can move within a preset activity space to switch between the use state and the non-use state. Optionally, the connection between the connector 2 and the support frame 3 can be set as a detachable or non-detachable connection. When set as a detachable connection, the connector 2 can be connected to the support frame 3 by detachable connection methods such as magnetic attraction connection and snap connection. At the same time, the connector 2 can be electrically connected to the battery cell assembly through connection methods such as a connector and a spring pin. With such a design, it is convenient to replace the connector 2. Different types of connectors 2 can be replaced to adapt to the charging interfaces of different devices, or a damaged connector 2 can be replaced, etc., thereby improving the adaptability of the mobile power supply and making the configuration more flexible. When the connection between the connector 2 and the support frame 3 is set as a non-detachable and movable connection method, the connector 2 can be flipped relative to the support frame 3 to switch as needed between the use state and the non-use state.

[0033] Specifically, to achieve reliable fixation of the support frame 3 and the housing 1, in the embodiment of the present utility model, a first connection structure 4 is provided on the housing 1, and a second connection structure 5 is provided on the support frame 3. The first connection structure 4 and the second connection structure 5 are structures that can cooperate with each other. When connecting, no other components are needed, and means such as welding and bonding are not required. Only through simple splicing operations can they be connected to each other. Optionally, according to different design schemes, the connection method between the first connection structure 4 and the second connection structure 5 can be one or a combination of connection methods such as magnetic attraction connection, snap connection, plug-in connection, clamping connection, etc., as long as the first connection structure 4 and the second connection structure 5 are adapted to each other and can be connected to each other through simple splicing operations. Optionally, for the setting method of the first connection structure 4 and the second connection structure 5, taking the first connection structure 4 as an example, it can be specifically formed integrally with the housing 1, or can be separately provided from the housing 1 and connected to the housing 1 through assembly or processing techniques. When using the integral forming method, the assembly steps can be further saved and the assembly operation can be simplified.

[0034] The mobile power supply provided by the embodiment of the present utility model includes a housing 1, a connection head 2, and a support frame 3. The connection head 2 can be connected to the support frame 3 in a variety of optional ways, with flexible configuration. At the same time, by providing a first connection structure 4 on the housing 1 and a second connection structure 5 on the support frame 3, only by mating the second connection structure 5 with the first connection structure 4 can the support frame 3 be fixed to the housing 1, and the assembly of the support frame 3 can be quickly completed. Through such a design, the assembly process of the support frame 3 does not require fasteners such as screws, nor the use of adhesives. The assembly operation only involves simple splicing operations, and reliable fixation of the support frame 3 and the housing 1 can be achieved. Therefore, the assembly operation is effectively simplified and the assembly efficiency is improved.

[0035] In some embodiments, such as Figure 2As shown, the first connection structure 4 includes a slot 41, and the second connection structure 5 includes a plug 51. The plug 51 is inserted into the slot 41. In some other embodiments, similarly, the second connection structure 5 includes a slot, and the first connection structure 4 includes a plug, and the plug is inserted into the slot. In still other embodiments, similarly, the first connection structure 4 includes a first plug and a first slot, the second connection structure 5 includes a second plug and a second slot, the first plug is inserted into the second slot, and the second plug is inserted into the first slot. It can be understood that in the above embodiments, the plugging method is adopted to connect the first connection structure 4 and the second connection structure 5, and only the slot and the plug need to correspond to each other. Taking the first connection structure 4 as an example, optionally, the first connection structure 4 can be just the slot 41, or just the plug, or can also include the first slot and the first plug at the same time, and there are no specific limitations on the number and specific shape of the slot or the plug, as long as it corresponds to the number of the slot or the plug of the second connection structure 5 and the shape is adapted.

[0036] In the above embodiments, the plug 51 and the slot 41 are inserted and connected to each other to achieve the connection. The design scheme is easy to implement and the assembly operation is simple. Moreover, there is a mutual abutting and limiting effect between the plug 51 and the slot 41, and the reliability of the connection is better.

[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the first connection structure 4 includes a first support member 42, and a first support position 421 is provided on the first support member 42. The second connection structure 5 includes a second support member 52, and a second support position 521 is provided on the second support member 52. The first support position 421 and the second support position 521 are connected to each other. Specifically, when the first support position 421 and the second support position 521 are connected to each other, they can abut against each other in multiple directions, thereby limiting the relative movement between the first support member 42 and the second support member 52 in these directions and achieving a good limiting effect.

[0038] Optionally, as Figures 4 to 6 shown, there are various design schemes for the first support position 421 and the second support position 521. For example, in some embodiments, as Figure 4 shown, the first support position 421 is set as a support platform substantially in an "L" shape, and the second support position 521 is set as a hook substantially in a "U" shape. The "U"-shaped hook can be inserted into the "L"-shaped support platform, so that the vertical part of the "L"-shaped support platform is located inside the "U"-shaped hook. At the same time, the horizontal part of the "L"-shaped support platform supports the bottom of the "U"-shaped hook. When designed in this way, at least the movement between the first support member 42 and the second support member 52 in the left-right direction and the up-down direction shown in the figure can be restricted. For another example, in some embodiments, as Figure 5As shown, there are two first support members 42, and the first support position 421 is set as a support platform approximately in an "L" shape. There are two second support members 52 corresponding to the first support members 42, and the second support position 521 is set as a lapping platform approximately in an "L" shape. In this way, when the second support member 52 is lapped on the first support member 42, the two "L"-shaped lapping platforms cooperate with the two "L"-shaped support platforms respectively, so as to be able to at least limit the activities of the first support member 42 and the second support member 52 in the left-right direction and up-down direction shown in the figure. For another example, in some embodiments, as Figure 6 shown, the first support position 421 is set as a "U"-shaped support platform, and the second support position 521 is set as a "U"-shaped hook. In this way, the two "U"-shaped structures are inserted into each other, and it can also at least limit the activities of the first support member 42 and the second support member 52 in the left-right direction and up-down direction shown in the figure. The above design solutions can be flexibly selected, and combinations and deformations can also be carried out on this basis.

[0039] It can be understood that the above implementation schemes can be combined as needed when there is no conflict. For example, taking the first connection structure 4 as an example, the first connection structure 4 can be composed only of the first support member 42, or only of the slot 41, or can also include both the slot 41 and the first support member 42 at the same time, and the number of the slot 41 and the first support member 42 can be set to one or more, with high design flexibility.

[0040] In some embodiments, as Figure 2 and Figure 3 shown, there are two first support members 42 and two second support members 52 arranged at intervals respectively. The support frame 3 is located between the two first support members 42, and the two second support members 52 are symmetrically arranged on the opposite sides of the support frame 3. When the above design is adopted, both sides of the support frame 3 are reliably fixed by being connected through the first support member 42 and the second support member 52 respectively. In this way, the force balance of the support frame 3 is better and it has good stability.

[0041] In some embodiments, as Figure 2As shown in the figure, the housing 1 includes a bottom case 11 and a cover plate 12. The battery cell assembly is disposed inside the bottom case 11, the first connection structure 4 is disposed on the bottom case 11, and an opening 111 is formed on the bottom case 11. The cover plate 12 is covered at the opening 111, a third connection structure 6 is disposed on the cover plate 12, and a fourth connection structure 7 is disposed on the support frame 3 corresponding to the position of the third connection structure 6, and the fourth connection structure 7 is connected to the third connection structure 6. It can be understood that for the specific design of the connection between the third connection structure 6 and the fourth connection structure 7, reference can be made to the design of the connection between the first connection structure 4 and the second connection structure 5 above, and a similar design concept can be adopted, which will not be elaborated here. It can be understood that the bottom case 11 and the cover plate 12 can be indirectly connected and fixed by connecting to the support frame 3 at the same time. In addition, corresponding clamping structures, plugging structures, etc. can also be provided on the bottom case 11 and the cover plate 12 to achieve direct connection, which can further improve the connection reliability. Through the above design, both between the bottom case 11 and the support frame 3 and between the support frame 3 and the cover plate 12 can be quickly assembled and connected through simple splicing operations, effectively improving the assembly efficiency.

[0042] In some embodiments, as Figure 2 shown, the third connection structure 6 is a connection groove, and the fourth connection structure 7 is a connection protrusion, and the connection protrusion is inserted into the connection groove. In other embodiments, similarly, the third connection structure 6 is a connection protrusion, and the fourth connection structure 7 is a connection groove, and the connection protrusion is inserted into the connection groove. In the above embodiments, the connection protrusion and the connection groove are inserted into each other to achieve quick connection. The design is easy to implement, the assembly operation is simple, and it has good connection reliability, and can reliably fix the installation position of the support frame 3.

[0043] In some embodiments, as Figure 3 shown, the mobile power supply further includes a rotating shaft 8, the rotating shaft 8 is fixedly connected to one of the support frame 3 or the connector 2, and is rotatably connected to the other of the support frame 3 or the connector 2, so that the connector 2 rotates relative to the support frame 3. Among them, as Figure 2 shown, a receiving groove 31 for receiving the connector 2 is provided on the support frame 3, and the connector 2 rotates relative to the support frame 3 to extend out of the receiving groove 31 to connect with the device to be charged or be received in the receiving groove 31. Optionally, the rotating shaft 8 can be fixed to the support frame 3 and rotatably connected to the connector 2; the rotating shaft 8 can also be fixed to the connector 2 and rotatably connected to the support frame 3, as long as the connector 2 can rotate relative to the support frame 3. Specifically, as Figure 3 shown, taking the rotating shaft 8 being fixed to the connector 2 and rotatably connected to the support frame 3 as an example, the rotating shaft 8 can be integrally formed with the connector 2, a positioning hole is formed on the support frame 3 for the rotating shaft 8 to pass through, and the rotating shaft 8 can rotate in the positioning hole and drive the connector 2 to rotate, so as to realize the rotation of the connector 2 relative to the support frame 3.

[0044] Specifically, the size and shape of the accommodating groove 31 can be designed according to the size and shape of the connector 2 so as to be able to accommodate the connector 2. For example, in some embodiments, Figure 2 As shown, the shape of the accommodating groove 31 is "U"-shaped, and the depth, width and other dimensions of the accommodating groove 31 can meet the requirements of fully accommodating the connector 2. When designed in this way, the curved surface shape of the accommodating groove 31 has better aesthetics, and the connector 2 can be completely received in the accommodating groove 31, which has a better hiding and protection effect on the connector 2.

[0045] In the above embodiment, the connecting head 2 can be rotated relative to the support frame 3 by using the rotating shaft 8 to be connected to the connecting head 2, so that the connecting head 2 can be flexibly switched between the use state and the non-use state. When it is needed, the connecting head 2 can be rotated to extend out of the receiving groove 31 provided on the support frame 3 for use, and when not in use, the connecting head 2 can be folded and stored in the receiving groove 31, saving space and facilitating the carrying of the mobile power supply. In addition, the connecting head 2 can be well protected without the need for additional protective covers and other components, and can also be well prevented from colliding with other objects. The design is ingenious and the use safety is good.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the side wall of the support frame 3 for forming the accommodating groove 31 extends through the housing 1 along the first direction, so that the connector 2 is exposed in the storage state, and the support frame 3 is spaced apart from the side wall of the housing 1 away from the first direction. The first direction is the direction of the end of the connector 2 for connecting to the device to be charged in the storage state.

[0047] For ease of explanation, the first direction is Figure 1 and Figure 2 Taking the direction A shown in the figure as an example, the side wall of the support frame 3 is arranged to penetrate the housing 1 along the direction A. At this time, the receiving groove 31 is open along the direction A, so that the connector 2 can be exposed in the storage state (the storage state can be referred to Figure 7As shown), with this design, the user can more conveniently touch the connector 2 from the exposed part of the connector 2, and flip the connector 2 to extend out of the accommodating groove 31 for use. The design is ingenious and does not require the use of other tools for operation, which is in line with daily usage habits. At the same time, the support frame 3 and the side wall of the shell 1 that deviates from the direction A are spaced apart. By simply designing the distance of the interval reasonably, the position of the connector 2 when it is flipped up for use can be determined. For example, the connector 2 can be placed in the middle of the top of the shell 1 when it is flipped up. This structure is more symmetrical, and when the connector 2 is connected to the device to be charged, the overall position of the mobile power supply relative to the device to be charged is better, which is conducive to improving the user experience. Moreover, by leaving a certain design margin between the support frame 3 and the side wall of the shell 1 that deviates from the direction A, the structural strength of the support frame 3 can be improved, and the reliability of the support can be improved.

[0048] Of course, it can be understood that the first direction described in the above embodiment is not limited to Figure 1 and Figure 2 The direction A shown may be other directions. For example, the first direction may also be the length direction of the shell 1 , etc. The embodiment of the utility model does not impose further restrictions on the selection of the first direction.

[0049] In some embodiments, Figure 3 As shown, the mobile power supply further includes a stopper 9, which is connected to the support frame 3 and / or the connector 2 to limit the rotation of the connector 2 relative to the support frame 3. Specifically, there are multiple design schemes for the stopper 9. Depending on the design, the principle of limiting the rotation of the stopper 9 is different, and the specific connection method of the stopper 9 is different. For example, in some embodiments, Figure 3As shown, the anti-rotation member 9 is an elastic piece, and the elastic piece is at least connected to the support frame 3. Among them, when the rotating shaft 8 is fixedly connected to the connecting head 2 and rotatably connected to the support frame 3, at least two limiting surfaces 81 that are angled with each other are provided on the rotating shaft 8 or the connecting head 2 (the limiting surface 81 in the figure is provided on the rotating shaft 8, or can be directly provided on the connecting head 2). The elastic piece abuts against any one of the limiting surfaces 81 to limit the connecting head 2 to a preset position. When the rotating shaft 8 is fixedly connected to the support frame 3 and rotatably connected to the connecting head 2, the above-mentioned limiting surface 81 is only provided on the connecting head 2. Specifically, when the elastic piece abuts against any one of the limiting surfaces 81, the rotation of the connecting head 2 is restricted, and it is necessary to overcome the elastic force exerted by the elastic piece on the limiting surface 81 to rotate. In this way, the problem that the connecting head 2 loosens when being disturbed can be effectively prevented. By designing the relationship between the limiting surface 81 and the rotation angle of the connecting head 2, when the elastic piece abuts against the limiting surface 81, the connecting head 2 is exactly in the best use state or storage state, so that it can be stably maintained in the current state and is not prone to loosening, improving stability. When it is necessary to rotate the connecting head 2, only an artificial rotational force needs to be applied to overcome the force of the elastic piece, so that the limiting surface 81 is separated from the elastic piece, thereby ensuring that the normal rotation operation is not affected and it is convenient to use.

[0050] It can be understood that the anti-rotation member 9 can also be set in other forms. For example, the anti-rotation member 9 can be set as a damping member. When the rotating shaft 8 is fixedly connected to the connecting head 2 and rotatably connected to the support frame 3, the damping member can be arranged at the rotational connection of the rotating shaft 8 and the support frame 3 to increase the frictional force of relative rotation through the damping member, thereby restricting the rotation of the connecting head 2. In addition, the anti-rotation member 9 can also be set in the form of multiple-section buckles, so that when the connecting head 2 rotates to a specific angle, it forms a snap connection with the anti-rotation member 9 to stay at the current angle. The above design schemes of the anti-rotation member 9 can also achieve the functions of restricting rotation and improving stability, and can be flexibly selected according to the actual situation.

[0051] Combined with the above embodiments, when the connecting head 2 can rotate relative to the support frame 3, as Figure 7 shown, the connecting head 2 can be rotated and switched to the illustrated storage state. In this way, the connecting head 2 does not protrude outward relative to the housing 1, does not occupy extra space, is convenient for storage, and is not easily collided with the outside world, which has a good protective effect on the connecting head 2.

[0052] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
