[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example
[0032] like Figure 1-6 As shown, an embodiment of the present invention provides a magnetic flip charger, which includes a charger body 1. The charger body 1 includes a bottom shell 11 and a front shell 12 movably disposed on the bottom shell 11. A bottom shell support 13 is disposed inside the bottom shell 11, and a front shell support 15 is disposed inside the front shell 12. A lower magnet 133 and an upper magnet 19 magnetically connected are respectively disposed on the bottom shell support 13 and the front shell support 15.
[0033] The bottom shell support 13 has a plurality of battery compartments 131 inside, and each battery compartment 131 has a convection hole 135. A circuit board 14 is provided at the bottom of the bottom shell support 13, and a spring piece 142 is provided on the circuit board 14, extending into the battery compartment 131 at one end.
[0034] The convection holes 135 are elongated, and several battery compartments 131 are arranged in two rows. The convection holes 135 on the two rows of battery compartments 131 are symmetrically arranged to achieve air convection.
[0035] The flip-top design ensures a clean and unobstructed appearance with no exposed mechanical parts, significantly enhancing the product's aesthetics. The concealed magnetic structure avoids the visual abruptness caused by traditional exposed magnets. The battery compartment 131 and convection holes 135 form an air circulation channel, effectively reducing temperature rise during charging. The spring contact design 142 increases the contact area compared to traditional spring structures, significantly reducing heat generation.
[0036] like Figure 3 As shown, in some embodiments, the number of spring contacts 142 is the same as the number of battery compartments 131 and corresponds one-to-one. One end of each spring contact 142 is soldered to a circuit board 14. The top of the circuit board 14 integrates a power interface 141 that extends to one side of the bottom shell 11.
[0037] The one-to-one correspondence between the spring contacts 142 and the battery compartment 131 ensures that each battery has an independent spring contact 142. The design of integrating the power interface 141 into the circuit board 14 simplifies the internal wiring and reduces the assembly complexity.
[0038] like Figure 5 As shown, in some embodiments, the lower magnet 133 is embedded on the top of one side of the bottom shell support 13, and a limiting seat 132 is provided on the other side of the bottom shell support 13. The top of the circuit board 14 also integrates a conductive post 143 whose top end passes through the limiting seat 132 and extends to the top of the bottom shell support 13.
[0039] The precise positioning of the limit seat 132 on the conductive post 143 ensures the assembly stability of the conductive post 143 and guarantees the stability of current transmission. The embedded lower magnet 133 is installed in a way that the magnet is not visible from the top of the bottom shell bracket 13, resulting in a more aesthetically pleasing hidden design.
[0040] like Figure 3-4 As shown, in some embodiments, the faceplate support 15 is provided with a first connector 151 and a second connector 152 on both sides, the upper magnet 19 is nested inside the second connector 152, and the faceplate 12 is provided with a second circuit board 16 inside. The bottom of the second circuit board 16 is integrated with a spring pin 18 whose bottom end passes through the first connector 151 and is in movable contact with the top of the conductive post 143.
[0041] The connector 152 has a built-in upper magnet 19 structure design, so the upper magnet 19 is not visible from the bottom of the faceplate bracket 15. The hidden design makes it more aesthetically pleasing. After the faceplate 12 and the bottom shell 11 are closed, the upper magnet 19 and the lower magnet 133 are attracted to each other, ensuring the stability of the faceplate 12 and the bottom shell 11 after they are closed. The retractable nature of the spring pin 18 ensures the contact stability between the spring pin 18 and the conductive post 143 after the faceplate 12 is closed.
[0042] like Figure 3-4 As shown, in some embodiments, the bottom of the circuit board 16 is also integrated with positive caps 161 that are the same number as the battery compartment 131 and are positioned opposite each other. A number of reinforcing ribs 112 are provided around the inner wall of the bottom shell 11, and the bottom of the lower magnet 133 is in contact with the top of at least one of the reinforcing ribs 112.
[0043] The reinforcing rib 112 serves a dual purpose: supporting the positioning of the lower magnet 133 and enhancing the structural strength of the bottom shell 11.
[0044] like Figure 4 As shown, in some embodiments, a plurality of reinforcing ribs 122 are provided around the inner wall of the face shell 12, and the top of the upper magnet 19 contacts the bottom of at least one of the reinforcing ribs 122.
[0045] The second reinforcing rib 122 has a dual function: supporting the positioning of the upper magnet 19 and enhancing the structural strength of the shell 12.
[0046] like Figure 3 As shown, in some embodiments, a plurality of buckles 111 are provided around the top of the inner wall of the bottom shell 11, and a plurality of buckle holes 136 are provided around the top of the bottom shell support 13, which are the same number as the buckles 111 and are engaged one-to-one.
[0047] The combination of buckle 111 and buckle hole 136 simplifies the assembly process, and multi-point fixing ensures the assembly stability of bottom shell 11 and bottom shell bracket 13. Both buckle 111 and buckle hole 136 are made of plastic. Plastic (such as charger BS, PP, P charger 66) has excellent elastic deformation ability and can achieve repeated snapping.
[0048] like Figure 4 As shown, in some embodiments, a hinge seat 134 is provided on the top of one side of the bottom shell support 13, and a notch is provided on one side of the bottom shell 11 for exposing the hinge seat 134. The side of the face shell 12 away from the upper magnet 19 passes through the notch and is provided with a hinge shaft 121 that is movably sleeved with the hinge seat 134.
[0049] The hinged structure between the front shell 12 and the bottom shell 11 enables the flip-top operation of the front shell 12, making operation more convenient. The notch allows air to flow, improving heat dissipation efficiency.
[0050] like Figure 1-4 As shown, in some embodiments, the bottom of the first connecting seat 151 and the second connecting seat 152 extends downward, and their horizontal height is lower than the bottom plane of the faceplate support 15. The faceplate 12 and the bottom shell 11 are provided with a handle groove 17 on one side.
[0051] The handle slot 17 makes it easier for users to open the front cover 12 to take out or put in the battery.
[0052] In summary, the built-in lower magnet 133 and upper magnet 19 optimize the appearance, and the hidden design makes the product more aesthetically pleasing. The battery compartment 131 is equipped with convection holes 135 to form an airflow channel, effectively reducing the charging temperature. The use of a spring sheet 142 to replace the traditional spring structure significantly increases the contact area, thereby reducing heat generation and improving charging efficiency. The hinge shaft 121, together with the handle groove 17, and the flip-top structure design ensure the integrity of the appearance and improve the convenience of use. At the same time, the internal reinforcing ribs 112 and 122 and the buckle 111 design enhance the structural stability. Overall, it achieves multiple advantages such as efficient heat dissipation, stable charging, and aesthetic appeal, which is economical and has broad application prospects.
