The shape of the hole 45Ah can be the same as the cross-sectional shape of the body 43b, and the disc 45A can rotate together with the pivot 43. A plurality of protrusions 45At can protrude from the rearward gripper 45G from one side (front) of the disc 45A and can be spaced apart from each other in the circumferential direction of the disc 45A. The protrusions 45At can be spaced apart from each other at 90-degree intervals. The size of the protrusions 45At can be the same as or correspond to the size of the fixing hole 45Ga. If the protrusions 45At are inserted into the fixing hole 45Ga, the rotation of the disc 45A and the pivot 43 can be restricted by the rear gripper 45G. If the protrusions 45At are inserted into the slot 45Gb, the disc 45A and the pivot 43 can rotate within the slot 45Gb.

[0116] A disc spring 45B may be located behind the disc 45A and may have a circular hole 45Bh through which the body 43b of the pivot shaft 43 passes. The disc spring 45B may be elastic and may protrude forward or backward. The disc spring 45B may generate an elastic force in the axial direction of the pivot shaft 43. For example, a pair of disc springs 45B may be provided. A first disc spring 45Ba may protrude rearward, and a second disc spring 45Bb may protrude forward.

[0117] A cap 45C may be located behind the disc spring 45B and may have a hole 45Ch through which the body 43b of the pivot shaft 43 passes. The shape of the hole 45Ch may be the same as the cross-sectional shape of the body 43b. The cap 45C may be fixed to the body 43b and may press the disc spring 45B and the disc 45A toward the rearward gripping portion 45G. The cap 45C may be threaded onto the body 43b, such as a nut. A first washer 45D may be located between the disc 45A and the disc spring 45B and may have a circular hole 45Dh through which the body 43b of the pivot shaft 43 passes. A second washer 45E may be located between the disc spring 45B and the cap 45C and may have a circular hole 45Eh through which the body 43b of the pivot shaft 43 passes.

[0118] Therefore, the front bracket 41 can rotate together with the pivot 43, the front grip 44G, the disc 45A, and the cap 45C. The front bracket 41 can rotate independently of the rear bracket 42, the rear grip 45G, the disc spring 45B, and the washers 44W, 45D, and 45E. In other words, even if the front bracket 41 rotates, the rear bracket 42, the rear grip 45G, the disc spring 45B, and the washers 44W, 45D, and 45E can remain stationary.

[0119] The pivot axis 43 provides the pivot axis of the front bracket 41. Under the elastic force of the disc spring 45B, the pivot angle of the front bracket 41 can be maintained as long as the front bracket 41 is not subjected to a force exceeding a specified level.

[0120] A first protrusion 41L can protrude rearward from the front bracket 41. A second protrusion 41R can protrude rearward from the front bracket 41. A stopper 42S can protrude from the top of the fixed base 42M and can be located on the rotational trajectory of the first protrusion 41L and the second protrusion 41R. The stopper 42S can restrict the pivoting of the front bracket 41 by interfering with the first protrusion 41L or the second protrusion 41R. The first protrusion 41L and the second protrusion 41R can be spaced 180 degrees apart from each other with respect to the pivoting axis of the front bracket 41, and the front bracket 41 can pivot within the range of +90 degrees to -90 degrees.

[0121] During the pivoting of the front bracket 41, the user can feel a tightening sensation from the fastening of the protrusion 45At and the mounting hole 45Ga or the fastening of the protrusion 45At and the slot 45Gb. For example, when the protrusion 45At disengages from the slot 45Gb and inserts into the mounting hole 45Ga, the user can perceive that the front bracket 41 is at an angle of 0 degrees, +90 degrees, or -90 degrees.

[0122] Reference Figure 8 and Figure 9 The retainer 46 may be located behind the mounting base 42M of the rear bracket 42. The retainer 46 may be located between the wings 42L and 42R of the rear bracket 42. The retainer 46 may be referred to as an ankle part 46, a hand part 46, or a grab part 46. The retainer 46 may include a front portion 461, a middle portion 462, and a rear portion 463. The front portion 461, the middle portion 462, and the rear portion 463 may be formed as a single body.

[0123] The front portion 461 may form the front part of the retainer 46. The front portion 461 may be located between the wings 42L and 42R of the rear bracket 42. The front portion 461 may include a first portion 461a, a second portion 461b, and a third portion 461c. The third portion 461c may generally have a hemispherical or bowl shape and may open toward the mounting base 42M.

The second portion 461b may extend from the third portion 461c toward the mounting base 42M and may face the second wing 42R.

[0124] The intermediate portion 462 may form the central portion of the retainer 46. The intermediate portion 462 may be located behind the front portion 461. The intermediate portion 462 may extend rearward from the third portion 461c of the front portion 461. Alternatively, the intermediate portion 462 may be omitted. In this case, the rear portion 463 may be directly attached to the front portion 461.

[0125] The rear portion 463 can form the rear portion of the retainer 46. The rear portion 463 can be located behind the middle portion 462. The rear portion 463 can extend rearward from the middle portion 462. The rear portion 463 can generally have a ring shape. The hole 463H can be formed by penetrating the center portion of the rear portion 463 in a vertical direction.

[0126] A tilt shaft 47 may extend in a direction intersecting with the wings 42L and 42R of the rear bracket 42. The tilt shaft 47 may pass through the first wing 42L, the first portion 461a, the second portion 461b, and the second wing 42R. A head 47a of the tilt shaft 47 may form one end of the tilt shaft 47 and may be inserted into a hole 42Lh fixed to the first wing 42L. A portion 47b of the tilt shaft 47 may form the other end of the tilt shaft 47 and may be inserted into a hole 42Rh fixed to the second wing 42R. A fastening member 47F, such as a nut, may be threaded onto the portion 47b of the tilt shaft 47 protruding from the second wing 42R.

[0127] At this point, a circular first hole 461ah can be formed in the first portion 461a, and a circular second hole can be formed in the second portion 461b. An inclined shaft 47 can pass through both the first hole 461ah and the second hole. The inclined shaft 47 and the brackets 41 and 42 coupled thereto can rotate relative to the retainer 46.

[0128] The elastic member 470 may be located between the first portion 461a and the second portion 461b of the retainer 46. The elastic member 470 may be wound multiple times around the outer peripheral surface of the inclined shaft 47 and may be elastic. The elastic member 470 may be a coil-shaped spring. The coil section 471 of the elastic member 470 may be the portion of the elastic member 470 wound around the outer peripheral surface of the inclined shaft 47. The support section 472 of the elastic member 470 extends from one end of the coil section 471, forming one end of the elastic member 470, and may be supported on the inner side of the front portion 461 of the retainer 46. The engagement section 473 of the elastic member 470 may extend from the other end of the coil section 471, forming the other end of the elastic member 470, and may be supported on the rear bracket 42. The support portion 42F may protrude rearward from the lower side of the fixing seat 42M of the rear bracket 42 and may be adjacent to the first wing 42L. The locking section 473 can be locked into the groove 42Fg of the support part 42F.

[0129] A disc spring 470S may be located between the elastic member 470 and the second part 461b. A tilting shaft 47 may pass through the disc spring 470S. The disc spring 470S may protrude toward the elastic member 470 or the second part 461b and may be elastic. The disc spring 470S may generate an elastic force along the axial direction of the tilting shaft 47. A washer 470W may be located between the second part 461b and the second wing 42R and may have a circular hole through which the tilting shaft 47 passes.

[0130] Thus, the front bracket 41 and the rear bracket 42 can rotate together with the tilting shaft 47 and the fastening member 47F (see reference). Figure 9 (RDa, RDb). The tilting shaft 47 can provide the axis of rotation of the brackets 41, 42 relative to the retainer 46. The tilting shaft 47 can provide the tilting axis of the brackets 41, 42. Under the action of the elastic force of the disc spring 470S, the tilting angle of the brackets 41, 42 can be maintained as long as the brackets 41, 42 are not subjected to a force exceeding a specified level.

[0131] Pin 46P can be fixed to the first part 461a and / or the second part 461b. The first pin 46Pa can protrude from the outer side of the first part 461a. The second pin 46Pb can protrude from the outer side of the second part 461b.

[0132] Guide grooves 42G can be formed on the first wing 42L and / or the second wing 42R. A first guide groove 42Ga can be formed from the rear end of the first wing 42L toward the inner side of the first wing 42L. A second guide groove 42Gb can be formed from the rear end of the second wing 42R toward the inner side of the second wing 42R. The first groove 42G1 of the guide groove 42G can be formed in an arc shape from a reference point 42G0 toward a first rotation direction RD1. The second groove 42G2 of the guide groove 42G can be formed in an arc shape from a reference point 42G0 toward a second rotation direction RDb opposite to the first rotation direction Rda.

[0133] Here, the tilting shaft 47 can rotate in either a first rotation direction RDA or a second rotation direction RDb. During the rotation of the tilting shaft 47 in the first rotation direction RDA, the pin 46P can move relative to the second groove 42G2. As the second groove 42G2 engages with the pin 46P, the rotation (tilting) of the tilting shaft 47 and the brackets 41, 42 connected thereto can be restricted. During the rotation of the tilting shaft 47 in the second rotation direction RDb, the pin 46P can move relative to the first groove 42G1. As the first groove 42G1 engages with the pin 46P, the rotation (tilting) of the tilting shaft 47 and the brackets 41, 42 connected thereto can be restricted.

[0134] Therefore, brackets 41 and 42 can tilt up and down within a specified angle range. For example, brackets 41 and 42 can tilt within a range of +25 degrees to -25 degrees.

[0135] Reference Figure 10 and Figure 11 The substrate 48 can be located behind the front bracket 41. The substrate 48 can be referred to as a PCB (Printed Circuit Board) 48 or board 48.

The substrate 48 can be disposed along the edge of the front bracket 41 and can be located on the back side of the front bracket 41. A circular stamped portion 41P can be formed on the inner side of the substrate 48.

[0136] The fastening member F1 can pass through the substrate 48 and engage with the hole 41Fh in the front bracket 41. The fastening member F1 can be a screw. The fastening member F1, fastened to the hole 41Fh, can be arranged along the substrate 48. Thus, the substrate 48 can be engaged with the rear of the front bracket 41.

[0137] The guide protrusion 48P can protrude from the front side of the substrate 48. The guide protrusion 48P can be adjacent to one end of the substrate 48. The guide protrusion 48P can be inserted into the guide hole 41G of the front bracket 41.

First terminal 48Ta can be configured close to one end of substrate 48, and second terminal 48Tb can be configured close to the other end of substrate 48. For example, relative to the center of the circle of substrate 48, first terminal 48Ta and second terminal 48Tb can be spaced 180 degrees apart from each other.

[0139] A hole 41M can be formed in the front bracket 41. A terminal 48T can be inserted into the hole 41M. A first terminal 48Ta can pass through the first hole 41Ma. A second terminal 48Tb can pass through the second hole 41Mb. Terminal 48T can protrude from the front of the front bracket 41.

[0145] Reference Figure 11 and Figure 12 The cable holder 49 may be located behind the base plate 48. The cable holder 49 may surround the side of the rear bracket 42. The wings 42L and 42R of the rear bracket 42 may be located in the hollow space 49H of the cable holder 49. The cable holder 49 may be referred to as a cable reel 49 or a cable wheel 49. The cable holder 49 may include a body 490, a first rim 491, and a second rim 492.

[0146] The main body 490 can have a hollow cylinder shape. The internal space of the main body 490 can form the hollow portion 49H of the cable holder 49. The central axis (i.e., the length axis) of the main body 490 can be aligned with the pivot axis 43 (see reference). Figure 10 Parallel. The main body 490 can be called cylinder 490.

[0147] The first rim 491 may be adjacent to one end of the body 490. The first rim 491 may protrude radially from said end of the body 490. The first rim 491 may protrude from the outer peripheral surface of the body 490 and may extend along the circumferential direction of the body 490.

The second rim 492 may protrude from the outer peripheral surface of the body 490 and may extend along the circumferential direction of the body 490. The second rim 492 may be referred to as a rear rim 492 or a second wall 492.

[0149] The first engagement portion 493 can protrude rearward from the second rim 492. The first engagement portion 493 can face the first wing 42L of the rear bracket 42. The second fastening member F2 can pass through the hole 493h of the first engagement portion 493 and be fastened to the hole 42Lf of the first wing 42L. The second fastening member F2 can be a screw. A groove 492G corresponding to the movement path of the head of the screw F2 can be formed on the back side of the second rim 492.

[0150] The second mating portion 494 can protrude rearward from the second rim 492. The second mating portion 494 can face the second wing 42R of the rear bracket 42. The second fastening member F2 can pass through the hole 494h of the second mating portion 494 and be fastened to the hole 42Rf of the second wing 42R. The second fastening member F2 can be a screw. A groove 492G corresponding to the movement path of the head of the screw F2 can be formed on the back side of the second rim 492.

[0151] Thus, the cable retainer 49 can be attached to the rear bracket 42. On the other hand, the first engagement portion 493 can cover and be spaced apart from the first pin 46Pa. The second engagement portion 494 can cover and be spaced apart from the second pin 46Pb. The first wheel rim 491 can be configured corresponding to the stamped portion 41P. Protrusions 41L, 41R (see reference) Figure 9 The protrusions can protrude rearward from the stamping part 41P and do not interfere with the first wheel rim 491. An arc or annular groove 491G can be formed on the front side of the first wheel rim 491, and the protrusions 41L and 41R can move along the groove 491G in a state that is separated from the groove 491G.

[0152] An opening 49P may be formed on the side of the cable holder 49. The opening 49P may be referred to as a hole 49P. A fastening member 47F may be located at the opening 49P.

[0153] Slot 49S may be formed on the side of cable holder 49. Slot 49S may also be formed at the bottom of cable holder 49. Slot 49S may be formed by cutting out a portion of the second ring 492 and a portion of the body 490. Furthermore, a portion of the first ring 491 may be cut out to form a portion of slot 49S.

[0154] A flange 495 may project radially from the edge of the first rim 491 toward the cable holder 49. The flange 495 may extend along the first rim 491. The flange 495 may be adjacent to the back surface of the substrate 48. The flange 495 may be located on the back surface of the substrate 48. A portion of the flange 495 may be formed in a portion of the first rim 491 where a slot 49S is formed. In other words, the slot 49S may be located between one end and the other end of the flange 495.

[0155] For example, flange 495 may form part of a ring. The angle between one end of flange 495 and the other end may be 90 degrees or an obtuse angle relative to the central axis of cable retainer 49. One end of flange 495 may be configured adjacent to slot 49S, and flange 495 may extend counterclockwise from said end.

[0156] As another example, flange 495 can form a ring.

[0157] Cable C can be located in slot 49S. Cable C can be secured in the portion of cable holder 49 where slot 49S is formed. Cable C can be located between the first ring 491 and the second ring 492, and can be configured along the body 490. Cable C can be routed counterclockwise along the body 490 and can be electrically connected to cable connector 48A. Front bracket 41 and base plate 48 can rotate relative to cable holder 49, and the axis of rotation of front bracket 41 and base plate 48 can be parallel to the central axis of pivot 43. Corresponding to the rotation of base plate 48, the degree to which cable C is wound around cable holder 49 can vary. For example, the more base plate 48 rotates counterclockwise around pivot 43, the more cable C can be wound around cable holder 49. For example, the more base plate 48 rotates clockwise around pivot 43, the more cable C can be unwound from cable holder 49. For example, cable C can be wound around body 490 approximately 0.5 to 1.5 times.

[0158] The flange 495 can extend along the cable C disposed on the body 490. The flange 495 can minimize the contact between the cable C and the substrate 48.

[0159] A cable groove 46G may be formed in the lower part of the retainer 46.

The third joint 41c can be configured correspondingly to the second groove 40Pc. The third joint 41c can be located in front of the second groove 40Pc. The second slot 40Sb can be formed between the third joint 41c and the second groove 40Pc.

[0168] Reference Figure 14 and Figure 2 The mounting base 15M can be recessed from the back of the rear cover 15, and the connector 40 can be inserted into the mounting base 15M. The protrusion 40Pa of the connector 40 can be inserted into the groove formed in the side wall of the mounting base 15M. The protrusion protruding from the side wall of the mounting base 15M can be inserted into the grooves 40Sa and 40Sb of the connector 40.

[0169] Thus, the connector 40 can be attached to the rear cover 15 of the display 10. The display 10 can rotate (pivot) together with the front bracket 41 of the connector 40.

[0170] Terminals 48Ta and 48Tb of connector 40 can be electrically connected to terminals of display 10. Terminals 48Ta and 48Tb can be electrically connected to the terminals of display 10 through holes formed in the bottom of mounting base 15M. The terminals of display 10 can be integrated into or formed in a substrate (i.e., PCB (Printed Circuit Board)) inside display 10.

[0171] For example, the substrate of display 10, which is electrically connected to terminals 48Ta and 48Tb, can be electrically connected to a battery (not shown) of display 10. The substrate of display 10 can also be referred to as a battery charger. In this case, cable C can pass through substrate 48 (see reference 48).

[0193] The pins 612 and 622 of the connector 60 provide a swivel axis for the connector 40 with the retainer 46. The retainer 46 can rotate about the pins 612 and 622. Due to the friction between the rear portion 463 and the bases 611 and 621, a force greater than a specified magnitude may be required to rotate the retainer 46. Alternatively, the connector 60 may also include a disc spring to increase the friction of the retainer 46. The disc spring may include at least one of a first disc spring and a second disc spring.

[0225] Reference Figure 25 and Figure 26 The support member 53 may include an elastic member 531, a stop member 532, a shaft 533, and a block 534.

[0226] The elastic member 531 can be located between the lower rods 511 and 512 of the lower arm 51. The elastic member 531 can be a spring in the form of a coil. The fixer 53F can be adjacent to one end of the lower arm 51 and can extend in a direction intersecting the lower rods 511 and 512. The fixer 53F can be fixed to the lower rods 511 and 512.

[0227] The stop 532 may be positioned opposite to the retainer 53F, with the elastic member 531 in between. The other end of the elastic member 531 may be located on the stop 532. The stop 532 may support the other end of the elastic member 531. The elastic member 531 between the retainer 53F and the stop 532 may compress or extend.

[0228] Shaft 533 can extend from stop 532 in a direction intersecting stop 532. Shaft 533 can be located outside elastic member 531.

[0229] Block 534 can be attached to the end of shaft 533. Block 534 can be connected to stop 532 via shaft 533.

The fastening member F5 and the block 534 can move along the slots 511S and 512S. Thus, the block 534 can be movably engaged with the lower arm 51.

[0232] Reference Figure 26 and Figure 27 The support arm 50 can rotate relative to the arm fixing seat 39. This rotation of the support arm 50 relative to the arm fixing seat 39 can be referred to as tilting of the support arm 50. The connector 614 of the joint 60 can rotate relative to the support arm 50.

[0233] The lower arm 51 can rotate about an axis parallel to the second lower pin P2. The upper arm 52 can rotate about an axis parallel to the second upper pin P4. The connector 60 can rotate about an axis parallel to the first lower pin P1. The connector 60 can rotate about an axis parallel to the first upper pin P3.

[0234] The length of the elastic member 531 of the support member 53 can be changed according to the rotation (tilt) of the support arm 50. The support member 53 can provide a force capable of counteracting the torque applied from the joint 60 to the support arm 50.

[0235] For example, refer to in sequence Figure 26 and Figure 27 The support arm 50 can rotate in the first rotation direction RD1. That is, the support arm 50 can tilt downwards. Correspondingly, the block 534 can move rearwards along the slot 512S. At this time, the stop 532 can also move rearwards together with the block 534, and the elastic member 531 can stretch (extend) while elastically deforming. Under the force provided by the elastic member 531, the support arm 50 can remain in a downward tilted state.

[0236] For example, referencing in reverse order Figure 26 and Figure 27 The support arm 50 can rotate in the second rotation direction RD2. That is, the support arm 50 can tilt upward. Correspondingly, the block 534 can move forward along the slot 512S. At this time, the stop 532 can also move forward together with the block 534, and the elastic member 531 can elastically recover. Under the force provided by the elastic member 531, the support arm 50 can maintain its upward tilted state.

[0237] The lower arm 51, upper arm 52, and pins P1, P2, P3, and P4 can be a four-bar linkage connecting the connector 60 and the arm mounting base 39. For example, the distance between the central axis of the first lower pin P1 and the central axis of the first upper pin P3 can be the same as the distance between the central axis of the second lower pin P2 and the central axis of the second upper pin P4. In this case, the angle of the connector 60 relative to the arm mounting base 39 can remain constant, regardless of the angle of inclination of the support arm 50. For example, the angle of the connector 60 can be the angle between the vertical axis passing through the center of the arm mounting base 39 and the top surface of the connector 614 of the connector 60. Thus, the angle of the display 10 coupled to the connector 60 can also remain constant.
