[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0038] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0039] like Figure 1 As shown, a head-mounted wireless charging assembly corresponding to an embodiment of the present utility model includes a mounting portion 1, a clamping portion 2 and a charging unit 3.

[0040] Further references Figure 3 The mounting portion 1 is used to cover the patient's head, specifically, to cover the top of the patient's skull. The first length D1 of the mounting portion 1 along the first direction is greater than the second length D2 of the mounting portion 1 along the second direction. The first direction is parallel to the patient's body width direction, and the second direction is perpendicular to the first direction. The first length D1 can be the maximum length of the mounting portion 1 along the first direction, and the second length D2 can be the maximum length of the mounting portion 1 along the second direction. When in use, the mounting portion 1 covers above the target component implanted in the patient's skull. By setting the second length D2 to be less than the first length D1, the mounting portion 1 does not need to cover the entire head of the patient, thereby reducing the material used for the mounting portion 1. In some specific embodiments, the first length D1 of the mounting portion 1 along the first direction can be 1.5 to 2 times the second length D2 of the mounting portion 1 along the second direction.

[0041] Further references Figure 5The charging unit 3 is installed on the side of the mounting portion 1 facing the patient's head, and is used to charge the target component implanted in the patient's head. The target component may be an implantable pulse generator. The charging unit 3 may include a shell 31 and a charging portion 32 disposed in the shell 31. The charging portion 32 may charge the target component implanted in the patient's head after being connected to a power source; for example, the charging portion 32 is a coil, and the charging portion 32 charges the target component by electromagnetic induction. Among them, the power supply for powering the charging portion 32 may be disposed in the shell 31 and connected to the charging portion 32 through a control circuit; or, the power supply for powering the charging portion 32 may also be a power supply device independent of the head-mounted wireless charging component, and the charging unit 3 is provided with a power supply interface 33 that passes through the shell 31, and the charging portion 32 is electrically connected to the power supply interface 33, and the power supply interface 33 may be connected to the independent power supply device through a wire, so that the independent power supply device can supply power to the charging portion 32 in the shell 31 through the power supply interface 33.

[0042] In some specific embodiments, the charging unit 3 is slidably connected to the mounting portion 1 so that the charging unit 3 can move relative to the mounting portion 1. When in use, it is only necessary to adjust the position of the mounting portion 1 so that the mounting portion 1 covers the target component implanted in the patient's skull; then further adjust the position of the charging unit 3 so that the position of the charging unit 3 corresponds to the position of the target component, and then charge the target component. By setting the charging unit 3 to be slidably connected to the mounting portion 1, the position of the charging unit 3 can be made more precise to effectively charge the target component; and a head-mounted wireless charging component can charge target components implanted at different positions in the patient's skull, without the need to set up multiple wireless charging components for target components at different implantation positions.

[0043] Further references Figure 1 and Figure 5 In some specific embodiments, the head-mounted wireless charging assembly further includes an adjustment assembly 4, which connects the charging unit 3 and the mounting portion 1, and allows the charging unit 3 to slide relative to the mounting portion 1. Specifically, the adjustment assembly 4 includes a connector 41, and the mounting portion 1 is provided with a slide groove 11. One end of the connector 41 is connected to the charging unit 3, and at least a portion of the connector 41 is received in the slide groove 11, so that the connector 41 can slide in the slide groove 11, and at the same time can drive the charging unit 3 to slide along the slide groove 11 and lock at the slide groove 11. The connector 41 can be connected to the mounting portion 1 in a damped sliding manner, that is, the connector 41 needs to overcome a certain resistance when sliding relative to the mounting portion 1, so that the charging unit 3 can remain in a fixed position after being adjusted to the desired position. The damped movable connection between the connector 41 and the mounting portion 1 can be achieved by a damper, the friction between the connector 41 and the mounting portion 1, the friction between the charging unit 3 and the patient's head, and the like.

[0044] In some preferred embodiments, the slide groove 11 passes through the mounting portion 1, and the end of the connecting member 41 facing away from the charging unit 3 protrudes from the mounting portion 1 and is connected to an adjusting member 42. The adjusting member 42 is located on the side of the mounting portion 1 facing away from the charging unit 3, so that the user can adjust the position of the adjusting member 42. The adjusting member 42 can drive the charging unit 3 to move through the connecting member 41. The adjusting member 42 can also be a locking nut, and the adjusting member 42 is fastened to the mounting portion 1 by screwing the adjusting member 42, so as to be locked in the slide groove 11. In addition, the dimension of the adjusting member 42 along the direction perpendicular to the extension of the slide groove 11 can be larger than the dimension of the slide groove 11 along the direction perpendicular to the extension of the slide groove 11, so that the mounting portion 1 forming the slide groove 11 can limit the movement of the adjusting member 42 into the slide groove 11 to prevent the adjusting member 42 from falling off.

[0045] In some specific embodiments, the slide groove 11 can extend along the first direction, so that the charging component can slide relative to the mounting portion 1 along the first direction. When in use, the mounting portion 1 is first adjusted along the second direction to cover the target component implanted in the patient's head, and then the position of the charging component is adjusted along the first direction so that the position of the charging component corresponds to the position of the target component. By setting the slide groove 11 to extend along the first direction, the charging component can be matched with the mounting portion 1, so that the charging unit 3 can be adjusted in a planar manner in both the horizontal and vertical directions, thereby increasing the adjustment space of the charging unit 3.

[0046] In some specific embodiments, the mounting portion 1 can be divided into two identical or substantially identical parts along the first direction, and the slide groove 11 is only provided on one of the parts. For example, the two parts are the first part and the second part, and the slide groove 11 is provided on the first part. When the target component is implanted in the left half of the patient's head, the mounting angle of the mounting portion 1 can be adjusted so that the first part is located on the left side; when the target component is implanted in the right half of the patient's head, the mounting angle of the mounting portion 1 can be adjusted, for example, the head-mounted wireless charging component is flipped over so that the first part is located on the right side; therefore, by adjusting the mounting angle of the mounting portion 1, the slide groove 11 only needs to be provided in the first part, so as to ensure that after the head-mounted wireless charging component is installed on the patient's head, the slide groove 11 is always located above the target component, thereby reducing the extension length of the slide groove 11 and reducing the difficulty of manufacturing the mounting portion 1.

[0047] A pair of clamping parts 2 are provided, and the pair of clamping parts 2 are respectively connected to the opposite ends of the mounting part 1 along the first direction, that is, the pair of clamping parts 2 can be distributed on both sides of the patient's head, and the pair of clamping parts 2 can apply clamping force to both sides of the patient's head, so that the head-mounted wireless charging component can be fixed on the patient's head by clamping. Among them, the clamping part 2 and / or the mounting part 1 can be made of a plastic material with good toughness. By providing a pair of clamping parts 2, the clamping part 2 and the mounting part 1 form a headband-type structure, which is convenient for the head-mounted wireless charging component to be installed on the patient's head.

[0048] In some specific embodiments, the clamping portion 2 is movably connected to the mounting portion 1, preferably hinged, so that the clamping portion 2 can be folded toward the side of the mounting portion 1 facing the patient's head. When the head-mounted wireless charging assembly is not in use, the pair of clamping portions 2 can be folded toward the mounting portion 1 to reduce the volume of the head-mounted wireless charging assembly, thereby reducing the space required for storing the head-mounted wireless charging assembly.

[0049] Further references Figure 5 and Figure 6 A first axial hole 12 can be provided at the end of the mounting portion 1 for connecting the clamping portion 2, and a second axial hole 21 can be provided at one end of the clamping portion 2 for connecting the mounting portion 1. When the clamping portion 2 is connected to the mounting portion 1, the first axial hole 12 and the second axial hole 21 can be connected. At this time, a rotating shaft 5 is used to pass through the first axial hole 12 and the second axial hole 21, so that the clamping portion 2 and the mounting portion 1 can be hinged, and the clamping portion 2 can be rotated and folded around the axis of the rotating shaft 5.

[0050] Further references Figure 4 and Figure 6 In some specific embodiments, the maximum distance between the rotating shaft 5 and the mounting portion 1 along the height direction is a first distance D3, and the maximum distance between the rotating shaft 5 and the clamping portion 2 along the height direction is a second distance D4, and the second distance D4 can be greater than the first distance D3; that is, the rotating shaft 5 is located in the upper half of the entire head-mounted wireless charging component in the height direction. When the head-mounted wireless charging component is in the storage state (such as Figure 6 As shown in the figure, the clamping portion 2 with a larger size in the height direction is folded, and the size of the head-mounted wireless charging assembly in the height direction is equal to or slightly larger than the third distance D3. The rotation axis 5 is arranged in the upper half of the head-mounted wireless charging assembly as a whole, which can reduce the size of the first distance D3, so that the volume of the head-mounted wireless charging assembly in the storage state is smaller and convenient for storage. In some preferred embodiments, the first distance D3 can be 0.4 to 0.7 times the second distance D4.

[0051] In some specific embodiments, a clamping end 22 may be further provided at one end of the clamping portion 2 away from the mounting portion 1. The inner wall of the clamping end 22 is used to fit the outer contour of the patient's ear, so that the clamping portion 2 can be used to clamp the patient's ear, further increasing the stability of the head-mounted wireless charging assembly when it is mounted on the patient's head.

[0052] Further references Figure 2 In some specific embodiments, a flexible contact layer 6 may be provided at the portion of the head-mounted wireless charging assembly that is in contact with the patient's head. The flexible contact layer 6 is made of a soft material, such as a soft rubber material. The use of a flexible contact layer 6 in contact with the patient's head can improve the patient's comfort, and the elastic properties of the flexible contact layer 6 can also reduce the sense of oppression generated between the head-mounted wireless charging assembly and the patient's head. The flexible contact layer 6 may be provided on the side of the mounting portion 1 facing the patient's head, and / or, on the side of the clamping portion 2 facing the patient's head, and / or, on the side of the charging unit 3 facing the patient's head, and / or, on the inner side of the clamping end 22. Among them, the flexible contact layer 6 on the side of the mounting portion 1 facing the patient's head and the flexible contact layer 6 on the side of the clamping portion 2 facing the patient's head may be an integrated structure.
