Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a wireless charging stand for a stylus. Background Technology

[0002] A stylus or capacitive stylus is a device used with electronic products (such as mobile phones and tablets) for input. Currently, mobile phones and tablets can be equipped with styluses for convenient input. Generally, to enable wireless charging of a stylus, a wireless charging stand (which is a major component of the stylus's wireless charging device) is usually included.

[0003] In existing technologies, traditional wireless charging stands for styluses typically have a limiting groove at each end of the magnetic rod, and then a limiting protrusion is designed on the plastic bracket (i.e., the bracket body) at the position corresponding to the limiting groove. Finally, the limiting protrusion on the plastic bracket (i.e., the bracket body) restricts the magnetic rod's degree of freedom in the Y direction (i.e., the third direction).

[0004] However, the magnetic rod of the traditional wireless charging stand for styluses lacks a structure that restricts the degree of freedom in the Z direction (i.e., the second direction). Therefore, when the magnetic rod is assembled onto the plastic stand (i.e., the stand body), the magnetic rod is prone to tilting in the Z direction (i.e., the second direction) due to the lack of a structure that restricts the degree of freedom in the Z direction (i.e., the second direction), which in turn affects the charging efficiency of the entire device. Utility Model Content

[0005] The present invention provides a wireless charging stand for styluses, which aims to solve at least some of the defects of existing wireless charging stands for styluses.

[0006] This utility model provides a wireless charging stand for a stylus. The wireless charging stand for the stylus includes:

[0007] The support body has a pair of opposing limiting blocks in a first direction; the support body has a first side and a second side opposite to each other in a second direction, and the first side has a receiving cavity; the first direction and the second direction are orthogonal to each other.

[0008] A pair of baffles; the pair of baffles are arranged along the first direction, and both of the pair of baffles are close to the second side; each of the baffles has a limiting plane, and the second direction is perpendicular to the limiting plane;

[0009] Each of the limiting blocks has a contact plane in the first direction; the contact planes of a pair of limiting blocks and the limiting planes of a pair of baffles enclose an installation space;

[0010] Each of the limiting blocks is provided with a limiting protrusion; the limiting protrusion protrudes from the contact plane and is located within the installation space;

[0011] Each of the limiting blocks has a first end face and a second end face opposite each other in the second direction, and the limiting protrusion extends from the first end face to the second end face;

[0012] A magnetic rod is assembled within the mounting space; the magnetic rod extends along an axial direction, and the axial direction is parallel to the first direction.

[0013] The magnetic rod has a pair of limiting grooves at its two opposite ends in the axial direction, and the limiting grooves have a shape and size that are adapted to the limiting protrusions;

[0014] A wireless charging assembly; a portion of the wireless charging assembly is wound around at least a portion of the magnetic rod, and another portion is disposed within the receiving cavity.

[0017] The winding portion and a pair of heads; the pair of heads are respectively disposed at opposite ends of the winding portion in the axial direction, and the winding portion and the pair of heads are integrally formed.

[0018] In some embodiments, the winding portion has a first cross-sectional area at both opposite end faces in the axial direction, and the head has a second cross-sectional area at both opposite end faces in the axial direction;

[0019] The first cross-section is smaller than the second cross-sectional area, so that the winding portion and the pair of heads enclose and form a wire-receiving groove.

[0020] In some embodiments, the head has opposing first and second sides in the radial direction, and the radial direction is parallel to the second direction.

[0021] The limiting groove is formed on the end face of the head away from the winding portion along the axial direction, and the limiting groove extends from the first side to the second side.

[0022] In some embodiments, the end face of the head away from the winding portion along the axial direction abuts against the contact plane of the limiting block to restrict the degree of freedom of movement of the magnetic rod in the first direction.

[0023] In some embodiments, a first or second side of the head abuts against the limiting plane of a pair of baffles to restrict the magnetic rod’s degree of freedom of movement in the second direction.

[0024] In some embodiments, the limiting groove and the limiting protrusion engage with each other to restrict the magnetic rod's degree of freedom of movement in the third direction;

[0025] The first direction, the second direction, and the third direction are orthogonal to each other.

In summary, compared with the wireless charging stand for traditional styluses, the movement freedom of the magnetic rod in the second direction is restricted, so that the magnetic rod will not tilt in the second direction, thereby improving the charging efficiency of the wireless charging stand for the stylus on the whole device.

[0041] Please see Figures 1-5 The wireless charging stand 100 for the stylus includes: a stand body 1, a limiting block 2, a pair of baffles 3, a magnetic rod 4, and a wireless charging component 5.

[0043] In addition, a pair of baffles 3 are arranged along the first direction 1001, and both baffles 3 are close to the second side 102; each baffle 3 has a limiting plane 301, and the second direction 1002 is perpendicular to the limiting plane 301.

[0044] In addition, each limiting block 2 has a contact plane 201 in the first direction 1001; the contact planes 201 of a pair of limiting blocks 2 and the limiting planes 301 of a pair of baffles 3 enclose and form an installation space 1004.

[0045] Specifically, each limit block 2 is provided with a limit protrusion 2011; the limit protrusion 2011 protrudes from the contact plane 201 and is located within the installation space 1004.

[0063] Additionally, the functional component 52 is housed within the receiving cavity 1011, and both protruding ends 511 of the coil 51 can be connected to at least a portion of the functional component 52.
