[0052] The front grab 45a is positioned between the head 44a and the front of the front bracket 42. The hole 45ah of the front grab 45a is aligned with the hole 42h of the front bracket 42 and may have the same shape as the hole 42h. The bolt 44b penetrates the holes 45ah, 42h. The protrusion 45af projects rearward from around the front grab 45 a, is spaced apart from each other at 90-degree intervals, and can be inserted and coupled to the groove or hole 42f of the front bracket 42. Thereby, the connection between the pivot shaft 44 and the front bracket 42 is further strengthened by the front grab 45a.

[0053] Referring to FIGS. 7 and 8, the rear bracket 43 is positioned behind the front bracket 42 and may include a mount 43F, a left wing 43L, and a right wing 43R. The mount 43F faces the front bracket 42 and has a circular mount hole 43Fh

[0054] . The body 44b of the pivot shaft 44 penetrates the mount hole 43Fh and can rotate independently of the mount 43F within the mount hole 43Fh. In other words, even if the pivot shaft 44 rotates, the rear bracket 43 does not rotate. For example, at least one washer 43Fw is positioned between the front bracket 42 and the mount 43F and has a circular hole through which the body 44b penetrates.

[0055] ​​​The left wing 43L may extend rearward from the left side of the mount 43F. The right wing 43R may extend rearward from the right side of the mount 43F. A plurality of members 4 5c: 45c1, 45c2, 45c3, 45c4, 45c5 described later are coupled to the mount 43F between the left wing 43L and the right wing 43R.

[0056] The rear grab 45c1 faces the washer 43 Fw with respect to the mount 43F and has a circular hole 45ch through which the body 44b of the pivot shaft 44 passes. The protrusions 45cf project forward from around the rear grab 45c1, are spaced apart from each other at 90-degree intervals, and are inserted and coupled to the groove or hole 42Ff of the mount 43F. Thereby the rear grab 45c1 can be coupled to the back surface of the mount 43F.

[0057] And the plurality of fixing holes 45ca and the plurality of slots 45cb are formed to penetrate the rear grab 45c 1 in the thickness direction of the rear grab 45c1 and are spaced apart from each other in the circumferential direction of the rear grab 45c1. The plurality of fixing holes 45ca and the plurality of slots 45cb are alternately positioned in the circumferential direction of the rear grab 45c1. For example, the fixing holes 45ca or the slots 45cb are spaced apart from each other at 90-degree intervals. In the circumferential direction of the rear grab 45c1 the length of the slot 45cb may be larger than the length of the fixing hole 45ca.

[0058] The disc 45c2 is positioned behind the rear grab 45c1 and may have a hole 45c2h through which the body 44b of the pivot shaft 44 passes. The hole 45c2h may have the same shape as the longitudinal cross-sectional shape of the body 44b. The plurality of bosses ​​​)45cc protrudes from the front of the disk 45c2 toward the rear lug 45c1 and is spaced apart from each other in the circumferential direction of the disk 45c2. For example, the bosses 45cc are spaced apart from each other at 90-degree intervals. The size of the boss 45cc is the same as or corresponds to the size of the fixing hole 45ca. That is, when the boss 45cc is inserted into the fixing hole 45ca, the rotation of the disk 45c2 and the pivot shaft 44 can be restricted by the rear lug 45c1. Also, when the boss 45cc is inserted into the slot 45cb, the disk 45c2 and the pivot shaft 44 can rotate within the locus of the slot 45cb.

[0059] The washer 45c3 is located behind the disk 45c2 and has a circular hole (not numbered) through which the body 44b of the pivot shaft 44 passes.

[0060] The disc spring 45c4 faces the disk 45c2 with respect to the washer 45c3 and has a circular hole (not numbered) through which the body 44b of the pivot shaft 44 passes. The disc spring 45c4 has elasticity and may bulge forward or backward. The disc spring 45c4 can generate an axial elastic force on the pivot shaft 44. For example, a pair of disc springs 45c4 may be provided. At this time, the first disc spring 45c41 and the second disc spring 45 c42 may bulge in different directions from each other. The first disc spring 45c41 may bulge backward, and the second disc spring 45c42 may bulge forward from behind the first disc spring 45c4 1. Thereby, the first and second disc springs The overall elastic forces of the discs 45c41 and 45c42 are strengthened.

[0061] The cap 45c5 is located behind the disc spring 45c4 and may have a hole 45c5h through which the body 44b of the pivot shaft 44 passes. The shape of the hole 45c5h may be the same as the shape of the longitudinal section of the body 44b. The cap 45c5 is coupled or fixed to the end of the body 44b.

[0062] As a result, the pivot shaft 44 can rotate together with the front bracket 42, the front grab 45a, the disc 45c2, and the cap 45c5. Also, the pivot shaft 45 can rotate independently of the washer 43Fw, the rear bracket 43, the rear grab 45c1, the washer 45c3, and the disc spring 45c4. In other words, even if the pivot shaft 45 rotates, the washer 43Fw, the rear bracket 43, the rear grab 45c1, the washer 45c3, and the disc spring 45c4 may not rotate.

[0063] Also, the user can pivot the head 10 (see FIG. 5) with respect to the pivot shaft 44. For example, the head 10 is pivoted within a range of +90 degrees to -90 degrees. Also, due to the elastic forces of the aforementioned disc springs 45c41 and 45c2, the head 10 can maintain a certain pivot angle as long as an external force above a certain level is not applied. Also, during the pivoting movement of the head 10, the user can feel the fastening feeling due to the fastening of the boss 45cc and the fixing hole 45ca or the slot 45cb. That is, the boss 45 ​​​​​​​​​​​​​​When the cc comes out of the slot 45cb and is inserted into the fixing hole 45ca, the user can feel that the head 10 is positioned at a pivot angle of 0 degrees, +90 degrees, or -90 degrees.

[0064] On the other hand, the left protrusion 42L is located between the center and the left side of the front bracket 42 and protrudes rearward from the front bracket 42. The right protrusion 42R is located between the center and the right side of the front bracket 42 and protrudes rearward from the front bracket 42. Also, the stopper 43 S protrudes upward from the upper side of the mount 43F and is located on the rotation trajectories of the left protrusion 42L and the right protrusion 42R. Thereby, the stopper 43S can limit the rotation of the front bracket 42 and the pivot shaft 44 to a certain angle.

[0065] Referring to FIG. 9, the holder 47 is positioned between the left wing 43L and the right wing 43R. The holder body 470 can cover the rear of the mount 43F of the rear bracket 43. The first part 47L protrudes from the left side of the holder body 470 toward the mount 43F and is adjacent to the left wing 43L. The second part 47R (see FIG. 7) protrudes from the right side of the holder 47 toward the mount 43F and is adjacent to the right wing 43R.

[0066] The tilt shaft may extend in the left - right direction. The tilt shaft 46 passes through the left wing 43L, the first part 47L, the second part 47R, and the right wing 43R.

A member (not shown) may be connected to the fourth portion (not shown) of the vertical member 61. do.

[0125] As a result, the upper shaft 62 can be detachably coupled to the vertical member 61. Also, the upper shaft 62 can move up and down along the lower shaft 63.

[0126] Referring to FIGS. 21 and 22, the rollers 66a, 66b, 67a, 67b are adjacent to the clamps 64, 65. For example, the first rollers 66a, 66b are adjacent to the first clamp 64 , and the second rollers 67a, 67b are adjacent to the second clamp 65.

[0127] The first rollers 66a, 66b include a first left roller 66a and a first right roller 66b. The body 66a1a of the first left pin 66a1 penetrates through the first left roller 66a and the left side part 61L of the vertical member 61. The flange 66a1b of the first left pin 66a1 is located between the first left roller 66 a and the left side part 61L. The first left roller 66a is coupled to the left side part 61L by the first left pin 66a1 . The body 66b1a of the first right pin 66b1 penetrates through the first right roller 66b and the right side part 61R of the vertical member 61. The flange 66 b1b of the first right pin 66b1 is located between the first right roller 66b and the right side part 61R. As a result, the first right roller 66b is coupled to the right side part 61R by the first right pin 66b1.

[0128] For example, the second rollers 67a, 67b may have the same shape as the first rollers 66a, 66b. That is, the foregoing description regarding the first rollers 66a, 66b may be equally applicable to the second rollers 67a, 67b. As a result, the second left roller 67a can be coupled to the left side part 61L , and the second right roller 67b can be coupled to the right side part 61R. ​

[0129] Also, the left rollers 66a and 67a are positioned between the third rib 30c and the fourth rib 30d and contact the third rib 30c and the fourth rib 30d. The right rollers 66b and 67b are positioned between the first rib 30a and the second rib 30b and contact the first rib 30a and the second rib 30b. For example the rollers 66a, 66b, 67a, and 67b may be provided with an oil groove through which a fluid such as oil flows For example, the rollers 66a, 66b, 67a, and 67b may contain a POM (Poly Oxy Methylene) material.

[0130] Thereby, the vertical member 61 can smoothly rise or fall inside the pole 30 by the rollers 66a, 66b, 67a, and 67b

[0131] Referring to FIGS. 21 and 23, the first left flange 641 of the first clamp 64 is positioned between the third rib 30c and the fourth rib 30d The first right flange 642 of the first clamp 64 is positioned between the first rib 30a and the second rib 30b. The first clamp 64 may include a first center protrusion 64a, a first left protrusion 64b, and a first right protrusion 64c

[0132] The first center protrusion 64a protrudes from the first semi-cylinder 650 toward the inside of the pole 30 and may contact the inside of the pole 30. For example, a plurality of first center protrusions 64a may be spaced apart from each other or may be aligned with each other. The first left protrusion 64b protrudes from the first left flange 641 toward the third rib 30c and may contact the third rib 30c The first right protrusion 64c protrudes from the first right flange 642 toward the second rib 30b ​​It may contact the second rib 30b. Thereby, the first center protrusion 64a, the first left protrusion 64b, and the first right protrusion 64c generate friction between the vertical member 61 and the pole 30.

The wireless charging unit 19 can be coupled to the frame 13 (see FIG. 3) and / or the back cover 1 5. The wireless charging unit 19 can provide electrical energy to the electronic device wirelessly by an inductive coupling method or a resonance coupling method . Such a wireless charging unit 19 is powered by the power supply board Pu

[0196] The inductive coupling method is such that when the intensity of the current flowing through either one of two adjacent coils (coil) changes, the magnetic field changes due to the current, and thereby the magnetic flux passing through the other coil changes, inducing an electromotive force . That is, even if two conductors are not moved spatially , when only the current of one of the two coils is changed while keeping the two coils close to each other, an induced electromotive force is generated in the other one coil. In this case, the frequency characteristics are not greatly affected, but the power efficiency may be affected according to the alignment and distance between the transmitting device (i.e., the wireless charging unit) and the receiving device (i.e., the terminal device) each including a coil . The resonance coupling method is based on the principle that when a resonance frequency is applied to one of two coils separated by a certain distance , a part of the magnetic field change amount generated is applied to the other coil of the same resonance frequency to generate an induced electromotive force. That is, when the transmitting and receiving devices

[0197] resonate at the same frequency respectively, since the electromagnetic wave is transmitted by the near-field electromagnetic field, the frequency is not greatly affected, but the power efficiency may be affected according to the alignment and distance between the transmitting and receiving devices. That is, when the transmitting and receiving devices resonate at the same frequency respectively, since the electromagnetic wave is transmitted by the near-field electromagnetic field, the frequency is not greatly affected, but the power efficiency may be affected according to the alignment and distance If the numbers are different, there is no energy transfer. In this case, the selection of frequency can become an important issue. Also, since there is no energy transfer between different resonance frequencies, the charging target device can also be selected by resonance frequency selection.

[0199] The aforementioned wireless charging unit 19 is electrically connected to the control unit C0. The control unit C0 can identify the position of the terminal device Mo mounted on the head 10 based on the information obtained from the gyro sensor 16 (see FIG. 32).
