[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.
[0028] With reference to Figures 1-6 , the mobile charging device of the present application comprises a charging main body 1, a first port 2 arranged on the charging main body 1, a connecting line 3 extending from the first port 2, a wireless charging port 4 arranged at the other end of the connecting line 3, the wireless charging port 4 being arranged on a sub-housing 41, and the sub-housing 41 being fixed to the charging main body 1 through a slide buckle structure 5. Figure 1 In the x-y plane defined by the x-axis and the y-axis in the definition, the x-y plane is a horizontal plane, the z-y plane defined by the z-axis and the y-axis is a vertical plane, and the z-x plane defined by the z-axis and the x-axis is also a vertical plane.
[0029] Further, the sub-housing 41 is used to accommodate the coil assembly 42, the magnetic attraction assembly and other electronic components required for the wireless charging port 4, and is structurally independent of the charging main body 1 and is electrically connected to the charging main body 1 through the connecting line 3. The slide buckle structure 5 comprises a clamping strip 51 arranged on the surface of the charging main body 1 and a clamping groove 52 arranged on the mounting surface 411 of the sub-housing 41, the clamping strip 51 can be arranged on any surface of the charging main body 1, the clamping groove 52 can be arranged on the side of the sub-housing 41 away from the coil assembly 42, and the side provided with the clamping groove 52 is defined as the mounting surface 411. However, in order to improve the compactness of the mobile charging device of the present application, the wireless charging port 4 can be arranged at the end of the longitudinal direction of the charging main body 1, and the length and width of the sub-housing 41 are substantially the same as those of the charging main body 1, so that the appearance of the whole after connection is more integrated, and adaptively, the first port 2 is close to the side provided with the wireless charging port 4.
[0030] With reference to Figures 2-6 , the clamping strip 51 in the slide buckle structure 5 comprises a longitudinal support strip 511 and a limiting cover 512 arranged on the top of the support strip 511, the width and length of the lower surface of the limiting cover 512 are greater than those of the support strip 511, so that the limiting cover 512 as a whole protrudes relative to the support strip 511, and in order to improve the smoothness of the clamping strip 51 sliding into the clamping groove 52, the top of the limiting cover 512 is configured as a circular arc surface, so that the cross-sectional shape of the clamping strip 51 is approximately mushroom-shaped. Correspondingly, the clamping groove 52 in the slide buckle structure 5 is provided with a variable diameter along the sliding direction of the clamping strip 51, i.e. the clamping groove 52 is divided into a starting section 511, an end section 522 and a transition section 523 connecting the starting section 511 and the end section 522, and the transverse width of the starting section 511 is different from that of the end section 522, which is beneficial to the clamping strip 51 sliding into and being limited in the clamping groove 52.
[0031] In a possible implementation, the width of the end section 522 of the card slot 52 is less than the maximum width of the limiting cover 512, so that the card slot 52 can abut against the limiting cover 512, thereby limiting the displacement of the card strip 51 in the card slot 52 to the two sides of the card slot 52 at the end section 522 of the card slot 52, and the card strip 51 and the card slot 52 can be prevented from separating from each other in the vertical direction. Further, the end section 522 of the card slot 52 can also abut against the front end of the card strip 51, and when the length of the end section of the card slot 52 is not less than one fourth of the total length of the card strip 51, sufficient contact area can be provided for the abutment of the two, further preventing the two from separating from each other.
[0032] The width of the start section 511 of the card slot 52 is greater than the maximum width of the limiting cover 512, so that the card strip 51 can be entirely inserted into the card slot 52, and the slightly wide start section 511 can improve the success rate of alignment of the card strip 51 and facilitate repeated disassembly and assembly. The widths of the start section 511 and the end section 522 of the card slot 52 are fixed, and the two are connected through a transition section 523, so that the card slot 52 is complete and continuous in structure.
[0033] Further, the card slot 52 further includes a slot cover, the slot cover including a top cover 524 covering from the start section 511 of the card slot 52 to the end section 522 of the card slot 52, and a side wall 525 covering the start section 511 of the card slot 52, so that the slot cover does not completely enclose the card slot 52, and the end section 522 and the transition section 523 of the card slot 52 are open, which is beneficial to simplify the fixing structure between the card strip 51 and the card slot 52 and facilitate heat dissipation of the wireless charging port 4. Further, the side wall 525 is connected to the mounting surface 411 of the secondary housing 41, so that the card slot 52 can be integrally formed with the mounting surface 411 of the secondary housing 41, improving the structural stability of the card slot 52. In order to strengthen the stability of the connection between the secondary housing 41 and the charging main body 1, the distance from the top cover 524 to the lower surface of the secondary housing 41 is not less than the height of the card strip 51, so that the card slot 52 can accommodate the entire card strip 51. Preferably, the distance from the inner wall of the top cover 524 to the inner wall of the mounting surface 411 is similar to the height of the limiting cover 512, so as to avoid loosening of the card strip 51 in the vertical direction after the card strip 51 is inserted into the end section of the card slot 52.
[0034] In a possible implementation, in order to improve the connection stability of the secondary housing 41 and the charging main body 1, two groups of mutually parallel slide buckle structures 5 can be provided. The sliding direction of the slide buckle structure 5 is parallel to the extension direction of the connecting line 3. Optionally, the sliding direction of the slide buckle structure 5 is opposite to the direction in which the connecting line 3 points to the wireless charging port 4. Figure 6, the wireless charging port 4 needs to be translated to the left after being sleeved into the card slot 52 by the initial segment 511 of the card slot 52, so that the card slot 51 enters the terminal segment 522 of the card slot 52, at this time, the direction of the connecting line 3 pointing to the wireless charging port 4 is right, and the connecting line 3 is pulled to the right by the virtual external force, so that the abutting degree between the card slot 52 and the card slot 51 is increased, and the wireless charging port 4 is better prevented from being pulled out of the charging main body 1. On this basis, the connecting line 3 can be used as a hanging rope.
[0035] Further, in order to improve the mechanical strength of the connecting line 3 as a hanging rope, a reinforcing sleeve 31 is arranged outside the connecting line 3, and the exposed range of the connecting line 3 is structurally reinforced and protected. The two ends of the reinforcing sleeve 31 are connected with the charging main body 1 and the auxiliary housing 41 respectively through the retreat-stop structures 32. The two retreat-stop structures 32 are similar: including a first retreat-stop ring 321 embedded in the outer surfaces of the charging main body 1 and the auxiliary housing 41 respectively, and a second retreat-stop ring 322 and a third retreat-stop ring 323 stacked in the inner side of the first retreat-stop ring 321 in turn, wherein the first retreat-stop ring 321 is visible outside the mobile charging device, the second retreat-stop ring 322 and the third retreat-stop ring 323 can be stacked with the first retreat-stop ring 321 in a detachable form, or can be integrally formed with the first retreat-stop ring 321; and the sizes of the second retreat-stop ring 322 and the third retreat-stop ring 323 can be different to adapt to the structural differences of the housings.
[0036] The mobile charging device of the present application can also include a second port 6 for external charging line, realizing wired charging. According to the related art, wired charging has higher efficiency and stability, and is also suitable for devices that cannot be wirelessly charged, thereby improving the universality of the mobile charging device.
[0037] The wireless charging port 4 and the second port 6 are respectively configured with a charge-discharge combination circuit, which can also be understood as the wireless charging port 4 and the second port 6 being connected to the same charge-discharge combination circuit at the same time, controlled by the charge-discharge combination circuit, thereby further improving the use flexibility of the mobile charging device of the present application, for example, wired charging or wireless charging can be selected according to actual conditions. Alternatively, the design of the charge-discharge combination circuit usually involves intelligent control of current direction, energy conversion and protection mechanism, and the core goal is to realize safe switching of the same circuit between charging and discharging modes. Through the combination of power electronic devices, intelligent control algorithms and protection circuits, the charge-discharge combination circuit realizes efficient and flexible management of energy, and is suitable for various energy storage and power supply scenarios.
[0038] In summary, the application provides a mobile charging device, which comprises a charging main body, a first port arranged on the charging main body, a connecting line extended from the first port, a wireless charging port arranged at the other end of the connecting line, the wireless charging port is configured with a secondary shell, and the secondary shell is fixed with the charging main body through a slide buckle structure; the wireless charging port is configured with a charging and discharging combination circuit.
