[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] The wireless charger provided by the embodiment of the present invention, as Figures 1-9 shown, includes: a wireless charger main body 1, a plastic shell 7, and a bracket module;

[0048] The plastic shell 7 is installed on the back of the wireless charger main body 1, and the front of the wireless charger main body 1 is connected to an electronic device and charges it;

[0049] The bracket module is fixed on the plastic shell 7 by injection molding to provide a supporting function for the electronic device.

[0050] In the above technical solution, the bracket module is fixed on the plastic shell 7 by injection molding, which can ensure the strength and stability of the magnetic wireless charger, making the whole wireless charger light and reducing costs (solving the problem that the traditional wireless charger uses hardware materials to solve the strength and stability); at the same time, the bracket module is fixed by injection molding, which can greatly reduce the installation space of the bracket module and make the whole product more compact and stable.

[0051] Optimizing the above technical solution, as Figure 4 shown, the bracket module includes: a hardware elastic sheet 3, a support frame 4, and a hardware seat 6;

[0052] The plastic shell 7 is provided with a through hole 71 penetrating its thickness; one side of the hardware elastic sheet 3 passes through the through hole 71 and is hinged to the support frame 4, and the other side of the hardware elastic sheet 3 is fixed to the hardware seat 6;

[0053] Among them, the hardware seat 6 and the inner surface of the plastic shell 7 form an integrated structure by injection molding.

[0054] In the above technical solution, the support frame 4 is located on the outer surface of the plastic housing 7. The support frame 4 can be rotated to the required angle according to the needs of the user, and then the charging function can be completed. The metal base 6 and the plastic housing 7 form an integrated structure, which improves the connection strength and stability between the metal base 6 and the plastic housing 7, and further improves the service life of the entire magnetic wireless charger. Preferably, a fixing groove 72 that is fixedly matched with the metal base 6 is provided on the inner surface of the plastic housing 7. Further, the cross-section of the metal base 6 is polygonal, and the cross-sectional shape of the fixing groove 72 is polygonal and matched with the metal base 6. After the metal base 6 is fixed in the fixing groove 72, each side of the metal base 6 abuts against the corresponding side of the fixing groove 72 one by one. Such a setting makes the fixation between the metal base 6 and the fixing groove 72 more tightly and firmly.

[0055] In order to further optimize the above technical solution, as Figure 4 shown, the metal spring piece 3 has a fixing portion 31 and a hinged portion 32;

[0056] The fixing portion 31 is fixed to the metal base 6, and the hinged portion 32 passes through the through hole 71 and is hinged to the support frame 4; the support frame 4 can rotate around the hinged portion 32 so that the wireless charger main body 1 forms an angle with the support surface.

[0057] In the above technical solution, by rotating the support frame 4 around the hinged portion 32, after rotating to a certain angle, the end of the support frame 4 that is not hinged to the hinged portion 32 is fixed to the support surface, which can meet the need for an angle between the wireless charger and the support surface in real life and facilitate the user to perform the charging function conveniently and quickly. It should be noted that the side of the wireless charger main body 1 facing away from the plastic housing 7 is used to charge the electronic device.

[0058] In this technical solution, as Figure 4 shown, it further includes: a fastener passes through the fixing portion 31 to fix the fixing portion 31 on the metal base 6. Using a fastener is simple and fast, and the connection structure is stable. In one embodiment, the fastener is a screw 2. The fixing portion 31 is provided with a threaded through hole 311, and a threaded hole 61 is provided on the surface of the metal base 6 facing away from the plastic housing 7. The screw 2 passes through the threaded through hole 311 and the threaded hole 61 in sequence to fix the fixing portion 31 on the metal base 6. In another embodiment, the fastener is a rivet, and the rivet passes through the fixing portion 31 to fix the fixing portion 31 on the metal base 6.

[0059] To optimize the above technical solution, in this technical solution, as Figure 3 and Figure 4 shown, the hinged portion 32 has a hinge pin 5;

[0060] The support frame 4 is symmetrically distributed with protrusions, and a notch 43 for mating with the middle part of the hinge pin 5 is formed between the protrusions. Each protrusion is provided with a pin hole for hinging, namely a first pin hole 41 and a second pin hole 42;

[0061] Both ends of the hinge pin 5 are respectively hinged to the first pin hole 41 and the second pin hole 42.

[0062] In the above technical solution, the support frame 4 is rotated relative to the wireless charger main body 1 through the first pin hole 41 and the second pin hole 42 and the setting of the hinge pin 5; and the cooperation between the pin hole and the hinge pin 5 can reduce mechanical failures and extend the service life of the magnetic wireless charger.

[0063] Optimizing the above technical solution, as Figure 4 shown, the hinge portion 32 is provided with a hinge through hole 321, and the hinge through hole 321 is clamped in the notch 43;

[0064] The hinge pin 5 is passed through the hinge through hole 321, and both ends of the hinge pin 5 are respectively hinged to the first pin hole 41 and the second pin hole 42.

[0065] In the above technical solution, the hinge pin 5 passes through the second pin hole 42, the hinge through hole 321 and the first pin hole 41 in sequence to connect the hinge portion 32 and the support frame 4; in some embodiments, the connection between the hinge pin 5 and the hinge through hole 321 is a rotational connection, and both ends of the hinge pin 5 are fixedly connected to the first pin hole 41 and the second pin hole 42 respectively.

[0066] In this technical solution, as Figure 5 and Figure 6 shown, it further includes: the hardware elastic sheet 3 includes: a connecting plate 33, and the middle part of the connecting plate 33 is located in the through hole 71; preferably, the through hole 71 is a square through hole;

[0067] Both sides of the connecting plate 33 are respectively connected to the fixing portion 31 and the hinge portion 32, and the connecting plate 33 is respectively arranged at an angle with the cross-sectional plane of the fixing portion 31 and the cross-sectional plane of the hinge portion 32;

[0068] Among them, the cross-sectional planes of the fixing portion 31 and the hinge portion 32 are parallel to each other.

[0069] In the above technical solution, when the cross-sectional plane of the support frame 4 is parallel to that of the fixing portion 31, the support frame 4 is in a storage state, and when the cross-sectional plane of the support frame 4 forms a certain angle with that of the fixing portion 31, the support frame 4 is in a working state; it should be noted that because the support frame 4 itself has a certain thickness, when a part of the end of the support frame 4 that cooperates with the hinge portion 32 rotates and abuts against the connecting plate 33, the self-locking of the support frame 4 can be achieved as Figure 2 shown.

[0070] Optimize the above technical solution, such as Figure 5 and Figure 6 As shown, the included angle between one side of the connecting plate 33 and the cross-sectional plane of the hinged portion 32 is the first included angle A;

[0072] Wherein, the first included angle is less than 90 degrees, and the second included angle B and the first included angle A are complementary.

[0073] In the above technical solution, through such a setting, a triangular space is formed among the support frame 4, the plastic shell 7 and the support surface, which is beneficial to the stability of the structure.

[0074] In this technical solution, it further includes: a groove 73 is provided on the outer surface of the plastic shell 7, and the groove 73 is used for accommodating the support frame 4.

[0075] In the above technical solution, when the user does not use the support frame 4, placing the support frame 4 in the groove 73 can save the storage space of the wireless charger.

[0076] Optimize the above technical solution, and reinforcing ribs 74 are provided on the part of the outer surface of the plastic shell 7 opposite to the groove.

[0077] In the above technical solution, setting the reinforcing ribs 74 is beneficial to the stability of the structure of this wireless charger.

[0078] In this technical solution, the connection between the plastic shell 7 and the wireless charger main body 1 is a snap connection. Preferably, an inner ring surface snap connection portion is provided on the inner ring surface of the plastic shell 7, and an outer ring surface snap connection portion is provided on the outer ring surface of the wireless charger main body 1.
