Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.

Fig. 1 is a perspective view of a head mount in an embodiment. Fig. 2 is a front projection view of the head mount in the embodiment shown in fig. 1. Fig. 3a and 3b are side projection views of the head mount in the embodiment of fig. 1. Fig. 4 is an isometric projection view of an exploded configuration of the head mount in the embodiment shown in fig. 1. Fig. 5 is a front projection view of an exploded configuration of the head mount in the embodiment of fig. 1. Fig. 6 is a rear projection view of an exploded configuration of the head mount in the embodiment of fig. 1. Referring to fig. 1 to 6, the head mount in this embodiment may include:

an arch assembly 10, the arch assembly 10 being operable to adjustably surround a head from a crown region and a rostral region;

a support element 50, the support element 50 being mountable to the arch element 60;

a turn-up assembly 60, the turn-up assembly 60 being operable to adjustably surround the head from the hindbrain region based on the support of the support assembly 50.

Wherein, in this embodiment, the support assembly 50 may be configured to:

in a first angular direction intersecting the profile plane of the arched profile of the arch assembly 10, there is a yaw adjustment margin f50 with respect to the arch assembly 10;

in a second angular direction parallel to the contour plane of the arched profile of the arch assembly 10, there is a torsion pendulum adjustment margin f40 with respect to the arch assembly 10.

Based on the above structure, the arch assembly 10 and the turn-up assembly 60 can respectively surround the head from different areas, so that the head-mounted support can realize multidirectional bag clamping to the head, wherein the surrounding of the head by the arch assembly 10 and the turn-up assembly 60 can be adjusted, so that the head-mounted support can match the head contour, and furthermore, based on the swing adjusting allowance f50 and the swing adjusting allowance f40 of the supporting assembly 50, the relative position constraint between the arch assembly 10 and the turn-up assembly 60 can be weakened, so as to help to improve the local matching degree of the head contour of the area in which the arch assembly 10 and the turn-up assembly 60 are located, so that the overall matching capability of the head-mounted support to the head contour can be improved, and further, the wearing stability of the head-mounted support and the comfort of a wearer are facilitated.

For a better understanding of the structure and adjustment principle of the head mount in this embodiment, the following description will be made on each part of the head mount in detail.

In embodiments of the present application, the arch assembly 10 may support at least one of a resilient adjustment in the radial direction of the arcuate profile, and a telescopic adjustment along the edge of the profile.

Fig. 7 is a schematic view of the assembled structure of the arch assembly of the head mount in the embodiment shown in fig. 1. Fig. 8 is a sectional view taken along line a-a of fig. 7. Fig. 9 is an exploded view of the arch assembly of the headgear support in the embodiment shown in fig. 1. Referring to fig. 7-9, in this embodiment, the arch assembly 10 may include a dome member 20, and a pair of arch arm members 30 mounted on opposite sides of the dome member 20.

As best seen in fig. 8 and 9, the arched main frame 20 may include a dome mid-section 21, and a pair of dome side sections 22 extending smoothly from both ends of the dome mid-section 21, and accordingly, the arm members 30 of each side may include an arm inner panel 31 and an arm outer panel 32 matching the curvature of the dome side sections 22 of that side, and the arm inner panel 31 and the arm outer panel 32 of the arm members 30 of each side may sandwich the dome side sections 22 of that side.

For example, an end of one of the inner and outer arch arm panels 31 and 32 (the inner arch arm panel 31 is taken as an example in the illustration of the embodiment) may have a retaining clip 36 through which the arch-side section 22 passes, and an end of the other of the inner and outer arch arm panels 31 and 32 (the outer arch arm panel 32 is taken as an example in the illustration of the embodiment) may have a plug-in tongue 37 inserted into the retaining clip 36 to achieve pre-assembly during assembly, and the inner and outer arch arm panels 31 and 32 may be connected to each other by riveting and splicing to achieve wrapping of the arch-side section 22.

In the case where the pair of inner and outer arch arms 31 and 32 sandwich the arch arm member 20 at the arch side section 22, the arch member 20 may further include an arch sheath 24, the arch sheath 24 may surround the arch center section 21, the arch side section 22 may protrude beyond the arch sheet sheath 24, and the thickness of the arch sheath 24 may be the same as or substantially the same as the thickness of the arch arm inner and outer arch arms 31 and 32 after the sandwich is split, so that the arch frame assembly 10 may have a smooth arch profile.

Based on the above-described structure of the arch assembly 10, the support assemblies 50 may be mounted in pairs to a pair of the arch arm members 30, for example, to the arch arm inner plates 31.

Further, in the above structure of the arch frame assembly 10:

the dome member 20 may have an elastic deformation allowance f20 in a radial direction of the arch profile of the arch frame assembly 10, and/or,

the arch arm member 30 may have a telescoping adjustment margin f30 along the contour edge of the arch profile of the arch assembly 10.

That is, the adjustable enclosure of the arch assembly 10 to the head from the parietal and lateral regions may have an adjustment margin in at least one of a radial direction and a contour edge of the arched contour of the arch assembly 10, i.e., at least one of the elastic deformation margin f20 and the telescopic adjustment margin f 30.

Based on the elastic deformation margin f20 of the dome member 20 in the radial direction of the arch profile of the arch assembly 10, the arch assembly 10 can exert elastic pressure on the head by elastic deformation of the dome member 20 when worn, i.e., the arch assembly 10 can form an elastic pinch on the head from the parietal and cephalic regions, and the arch profile of the arch assembly 10 can also be adaptively adjusted by elastic deformation of the dome member 20 in response to contact of the arch assembly 10 with the parietal by the dome member 20 and contact reaction force of the arch arm member 30 with the cephalic side when worn, so that the arch profile can be adaptively adapted to the head profiles of the parietal and cephalic regions.

In one example of this embodiment, in order to provide the dome member 20 with the elastic deformation allowance f20 in the radial direction of the arch profile of the arch frame assembly 10, the dome member 20 may be made of an arch-shaped plate material of a metal material or a plastic plate material having elastic characteristics.

The contour dimension of the arcuate contour of the arch assembly 10 can be adjusted based on the telescopic adjustment margin f30 of the arch arm member 30 along the contour edge of the arcuate contour of the arch assembly 10. In the case where the arch member 30 has the telescopic adjustment margin f30, the plug-in tongue 37 inserted into the retaining clip 36 may be interference-fitted with the retaining clip 36 in the width direction of the arch member 30, and the plug-in tongue 37 and the retaining clip 36 need to be provided with a sufficient clearance in the thickness direction of the arch member 30, which may be larger than the thickness of the arch member 20 in the arch side section 22, so as to avoid obstructing the relative sliding between the arch side section 22 and the arch member 30.

In one example of this embodiment, to provide the telescopic adjustment margin f30 of the arch arm member 30, the arch arm member 30 may be slip-fit with the dome member 20, i.e., the inner and outer arch arm panels 31, 32 of each side of the arch arm member 30 may form a slidable trap for the side dome segments 22 of that side.

For example, the arch arm member 30 may be in a damped sliding fit with the arch member 20 along the contour edges of the arch profile of the arch assembly 10. Specifically, if the arch arm members 30 are in damped sliding engagement with the dome members 20 along the contoured edges of the arched profile of the arch assembly 10, the arched main frame 20 and the arch arm members 30 may achieve a damped sliding engagement through a meshing transmission, i.e., a meshing transmission may provide a damping characteristic for the sliding engagement of the arch arm members 30 with the dome members 20.

With particular attention to fig. 8 and 9, taking the case where the arched main frame 20 and the arched arm member 30 are engaged in a damped sliding fit by meshing transmission, the arched side section 22 may be provided with the engaging teeth 23, and one of the arched arm inner plate 31 and the arched arm outer plate 32 may be provided with the row of engaging teeth 33 engaged with the engaging teeth 13, wherein the row of engaging teeth 33 is aligned in the extending direction of the arched arm member 30 (i.e., the contour edge of the arched contour of the arch unit 10), so that the arched arm member 30 and the arched main frame 20 are engaged in a damped sliding fit along the contour edge of the arched contour of the arch unit 10 by meshing transmission of the engaging teeth 23 and the row of engaging teeth 33. Further, both ends of the row of engaging teeth 33 may be provided with a stopper structure for preventing disengagement from the engaging teeth 13 in the transmission direction of the engagement transmission. Additionally, in order to maximize the size of the arched main frame 20 utilized by the range of adjustment of the arched profile, the engaging teeth 23 may be deployed at the extended distal end of the dome member 20 (i.e., the dome side sections 22).

In the illustration of this embodiment, the arch member 20 (i.e., the arch side section 22) is disposed with the engaging teeth 23, the arch arm member 30 (the arch arm inner plate 31 or the arch arm outer plate 32) is disposed with the engaging teeth row 33, but it is understood that the engaging teeth are disposed on the arch arm member 30 (e.g., on the extended end of the arch arm member 30 on the side away from the arch member 20), and the engaging teeth row is disposed on the arch member 20, and the engaging transmission between the arch main frame 20 and the arch arm member 30 can be realized by the same manner. Also, in the case where the dome member 20 (i.e., the dome-side section 22) is disposed with the engaging teeth 23, the arch arm member 30 (the arch arm inner panel 31 or the arch arm outer panel 32) is disposed with the engaging teeth row 33, in the illustration expression of this embodiment, it is exemplified that the engaging teeth 23 are disposed on the inner arc surface of the dome member 20 (i.e., the dome-side section 22), and the engaging teeth row 33 is disposed on the arch arm inner panel 31 (e.g., on the extending end of the arch arm inner panel 31 on the side away from the dome member 20), but it is understood that the engaging teeth row 33 is disposed on the outer arc surface of the dome member 20 (i.e., the dome-side section 22), and the engaging teeth row 33 is disposed on the arch arm outer panel 32 (e.g., on the extending end of the arch arm 32 on the side away from the dome member 20), the engaging transmission between the arch main frame 20 and the arch arm member 30 can be realized as well.

In an embodiment of the present application, the support assembly 50 may be in damped rotational engagement with the arch assembly 10 to provide the support assembly 50 with a yaw adjustment margin f50 relative to the arch assembly 10 (e.g., the arch arm member 30) in a first angular direction intersecting a contoured plane of the arcuate profile of the arch assembly 10; also, the axis of rotation C40 of the support member 50 in rotationally damped cooperation with the arch member 10 may be configured to be deflectable in a second angular direction parallel to the contoured plane of the arcuate profile of the arch member 10 to provide a torsional pendulum adjustment margin f40 for the support member 50 relative to the arch member 10 (e.g., the arm member 30) in the second angular direction.

Fig. 10 is a schematic view of the assembled structure of the support assembly of the head mount in the embodiment shown in fig. 1. Fig. 11 is an exploded view of the support assembly of the headgear of the embodiment shown in fig. 1. Fig. 12 is a schematic partial assembly of the support assembly and arch assembly of the headgear support of the embodiment shown in fig. 1. Fig. 13 is a partial assembled structural view of the support assembly and arch assembly of the headgear support of the embodiment shown in fig. 1. Fig. 14 is a sectional view taken along line B-B in fig. 13. Referring to fig. 10-14, in this embodiment, arch assembly 10 may have an adjustment mounting socket 35 and support assembly 50 may have a mounting socket 55.

In one example of an embodiment of the present application, the adjustment mounting boss 35 of the arch assembly 10 may be located at the arch arm members 30, and the adjustment mounting boss 35 may be protruded at outer sides of the pair of arch arm members 30 facing away from each other to avoid the adjustment mounting boss 35 from pressing head-side between the arch arm members 30. For example, the adjustment mounting tube base 35 may be positioned on the outer arm plates 32 of the arm members 30, the adjustment mounting tube base 35 may protrude outward of the arm outer plates 32 away from the arm inner plates 31, and the arm inner plates 32 of the pair of arm members 30 may be opened with escape openings 34 communicating with the openings of the adjustment mounting tube base 35.

In one example of an embodiment of the present application, the support assembly 50 may include a support arc plate 51, and the mounting axle seat 55 may be located on the support arc plate 51 (e.g., an extended end of the support arc plate 51).

The mounting axle seat 55 of the support assembly 50 may be coaxially coupled to the mounting axle 42 received within the adjustment mounting barrel 35 of the arch assembly 10 (e.g., the arch arm member 30) via the damping pivot 41. for example, the mounting axle 42 coaxially coupled to the damping pivot 41 may enter the adjustment mounting barrel 35 of the outer arch arm panel 32 through the relief opening 34 of the inner arch arm panel 31.

The coaxial connection of the mounting shaft seat 55 with the fitting shaft element 42 may form a rotation axis C40 with damped rotation fit, and this rotation axis C40 formed in this way is used to enable: the support assembly 50 forms a damped rotational engagement with the arch assembly 10 (e.g., the arch arm member 30) in a first angular direction intersecting a contoured surface of the arcuate profile of the arch assembly 10.

The damped rotational engagement between the support assembly 50 and the arch assembly 10 (e.g., the arch arm member 30) may also provide the support assembly 50 with a wide range of swing amplitudes relative to the arch arm member 30 that may be beyond a swing adjustment margin f50 to allow the headgear mount to be switched between the stowed and use states by swinging of the support assembly 50 and to provide the support assembly 50 with a swing adjustment margin f50 when the headgear mount is in the use state, i.e.:

when the headgear is in the stowed state, the support assembly 50 can overlap the arched arm member 30 by swinging about the rotation axis C40 so that the headgear can be packaged in a state that occupies a relatively small space;

when the headgear is in use, the support assembly 50 can intersect the arch arm member 30 at a target adjustable angle in the first angular direction by swinging about the rotation axis C40, the target angle floating within the swing adjustment margin f 50.

With particular attention to fig. 14, the mounting shaft member 42 and the adjustment mounting barrel seat 35 may have a fit clearance therebetween to allow the rotation axis C40 formed by the coaxial connection of the mounting shaft seat 55 and the mounting shaft member 42 to be deflected in a second angular direction parallel to the contour plane of the arcuate profile of the arch assembly 10.

Therein, the yaw of the rotation axis C40 relative to the arch assembly 10 may be used only to provide the torsional pendulum adjustment margin f 40.

To achieve the yaw of the rotation axis C40, the adjustment mounting socket 35 of the arch assembly 10 (e.g., the arch arm member 30) has a cylindrical wall circular hole 351, and the fitting shaft 42 may have an axial long hole 421, for example, the fitting shaft 42 may have an axial lug 422 protruding in the axial direction to provide a sufficient axial space for deploying the axial long hole 421 with the axial lug 422, that is, the axial long hole 421 may extend from a main body portion of the fitting shaft 42 to the axial lug 422.

Wherein, the assembling shaft member 42 can be constrained in the adjusting installation cylinder seat 35 by the radial shaft member 43 penetrating the cylinder wall round hole 351 and the axial long hole 421, for example, the radial shaft member 43 can be selected to be a pin. Thus, the fitting shaft member 42 can be swung in a second angular direction parallel to the contoured surface of the arcuate profile of the arch member 10 to induce the swing of the rotational axis C40 based on the sliding fit of the radial shaft member 43 with the axially elongated hole 421.

In embodiments of the present application, the turn-up assembly 60 may include a turn-up shell 61 having a conforming arc on its outer surface, and the adjustable enclosure of the head by the turn-up assembly 60 may be targeted to match the conforming arc of the turn-up shell 61 to the contour of the head in the hindbrain region. Wherein the cambered surface attitude of the attached cambered surface can be adjusted in response to at least one of the swing adjustment allowance f50 and the torsion adjustment allowance f40 of the supporting component 50, and can be adaptively changed in response to the attachment floating allowance f60 of the anti-tipping component 60 relative to the supporting component 50.

Referring to fig. 15 to 19, in this embodiment, the supporting member 50 may include a fastening cap 56 detachably mounted on the supporting arc plate 51, and the turn-up member 60 may include a supporting shaft 62 protruding from an inner surface of the turn-up housing 61, and an end ball 63 located on the supporting shaft 62, wherein an outer diameter of the end ball 63 is larger than an outer diameter of the supporting shaft 62.

Wherein, the turn-up housing 61 can be disposed on a first side (e.g., inner arc side) of the supporting arc plate 51, and the supporting vertical shaft 62 can be disposed through the supporting arc plate 51, such that the end ball 63 is located on a second side (e.g., outer arc side) of the supporting arc plate 51.

For example, the support assembly 50 may include a fitting through hole 52 and a mounting through hole 53 opened in the support arc plate 51, wherein the bore diameter of the fitting through hole 52 is larger than the outer diameter of the end ball 63, the bore diameter of the mounting through hole 53 is larger than the outer diameter of the support vertical shaft 62 and smaller than the outer diameter of the end ball 63, and a communication sliding slot 54 is provided between the fitting through hole 52 and the mounting through hole 53, the slot width of the communication sliding slot 54 is larger than the outer diameter of the support vertical shaft 62 and smaller than the bore diameter of the mounting through hole 53, so that, after the end ball 63 penetrates from the first side of the support arc plate 51 to the second side of the support arc plate 51 through the fitting through hole 52, the support vertical shaft 62 may be allowed to move into the mounting through hole 53 along the communication sliding slot 54, and the end ball 63 is limited at the mounting through hole 53 on the second side of the support arc plate 51.

And, a fastening cap 56 is detachably mounted on the second side of the supporting arc plate 51, so that the turn-up assembly 60 has a fitting floating margin f60 relative to the supporting assembly 50 by the spherical fit with the end ball 63.

For example, the support assembly 50 may further include a snap hole groove 57 disposed at the second side of the support arc plate 51, an edge of the snap cap 56 may have a snap leg 561, and the snap cap 56 may be detachably fixed to the support arc plate 51 by snap fitting of the snap leg 561 in the snap hole groove 57. Also, with particular attention to fig. 16 and 17, the engagement cap 56 has a spherical recess 563 disposed in alignment with the mounting through hole 53, the spherical recess 563 being for forming a spherical fit with the end ball 63, and the engagement cap 56 may further have an anti-disengagement table 562 disposed adjacent to the spherical recess 563, and when the spherical recess 563 forms a spherical fit with the end ball 63, the anti-disengagement table 562 may be filled in the mounting through hole 52 and the communication chute 54 to prevent the support shaft 62 in the mounting through hole 53 from moving back to the mounting through hole 52 along the communication chute 54, thereby preventing the end ball 53 from disengaging from the mounting through hole 52.

In this embodiment, the floating allowance f60 for the engagement between the turn-up assembly 60 and the support assembly 50 can be limited in the engagement direction of the two, and correspondingly, the end ball 63 can be provided with a rotation-stopping groove 64 extending in a direction parallel to the support vertical shaft 62, and the rotation-stopping groove 64 is used for being limited and clamped by at least one of the support arc plate 51 and the buckling cap 56 to form rotation-stopping restriction in a direction surrounding the support vertical shaft 62, i.e., the relative angle between the turn-up housing 61 of the turn-up assembly 60 and the support arc plate 51 of the support assembly 50 in the rotation direction surrounding the support vertical shaft 62 is kept constant.

For example, the support arc plate 51 may have the first rotation-stopping protrusion 530 in the mounting through-hole 53, and/or the snap cap 56 may have the second rotation-stopping protrusion 564 formed on the groove wall of the spherical groove 563, and at least one of the first rotation-stopping protrusion 530 and the second rotation-stopping protrusion 564 may form the aforementioned rotation-stopping restriction with the rotation-stopping groove 64.

In addition, in the embodiments of the present application, when the head mount needs to load the portable device, the portable device may be mounted to the arch assembly 10 (e.g., to the arm member 30 of the arch assembly 10) using a loading mechanism, and when the loading mechanism is mounted to the arch assembly 10 (e.g., to the arm member 30), the portable device may be conveniently detached from the loading mechanism.

Fig. 20 is an exploded view of the loading mechanism of the headgear support shown in the embodiment of fig. 1. Fig. 21 is a schematic view of the assembly structure of the loading mechanism of the head mount in the embodiment shown in fig. 1. Fig. 22 is a cross-sectional view taken along line D-D of fig. 21. Fig. 23 is a schematic view illustrating a quick release mechanism of the loading mechanism of the head mount in the embodiment shown in fig. 1. Fig. 24 is a sectional view taken along line E-E in fig. 23. Referring to fig. 20 and fig. 21 to 24, the loading mechanism of the head mount in this embodiment may include:

a loading bracket 70, the loading bracket 70 being mounted to the arch assembly 10 (e.g., the arch arm member 30);

a loading dock 81, the loading dock 81 being used to load a portable device;

a quick release knob 82, the quick release knob 82 being used for detachably mounting the loading base 81 on the loading bracket 70, wherein:

in response to the quick release knob 82 being screwed in the first operating direction, the loading base 81 may be locked to the loading bracket 70 by a fitting connection with the quick release knob 82;

in response to the quick release knob 82 being screwed in the second operating direction, the loading base 81 may be allowed to disengage from the loading bracket 70 by disengaging the quick release screw 82.

Based on the above structure, when the loading bracket 71 is mounted to the arch assembly 10 serving as the carrier, stable loading and convenient detachment of the portable device in the arch assembly 10 can be allowed, and thus, it can be applied to a head-mounted mode of the portable device using the arch assembly 10 as the carrier, and flexible switching of the portable device between the head-mounted mode and the hand-held mode can be considered.

In one example of the embodiment of the present application, the loading bracket 70 includes a bracket main body 71, and a quick release mounting boss 72 formed on the bracket main body 71, wherein:

in response to the quick-release knob 82 being screwed in the first operation direction, the loading base 81 can be locked in the barrel cavity of the quick-release assembly barrel seat 72 through the assembly connection with the quick-release knob 82, so as to realize the fitting fit between the loading base 81 and the loading bracket 70, which is beneficial to improving the installation stability of the portable device loaded on the loading base 81 in the loading mechanism;

in response to the screwing of the quick release knob 82 in the second operating direction, the loading base 81 can be allowed to be removed from the cylinder cavity of the quick release cylinder fitting holder 72 by the fitting release with the quick release screw 82, that is, the fitting fit between the loading base 81 and the loading bracket 70 for improving the mounting stability, without affecting the operational convenience for switching the portable device from the head-mounted mode to the hand-held mode.

In one example of the embodiment of the present application, in order to facilitate assembly connection and disassembly in response to screwing based on the quick release knob 82, the loading base 81 and the quick release knob 82 may employ threaded engagement.

Accordingly, the loading base 81 may include a base threaded portion 810 (e.g., an internally threaded bore recessed within the loading base 81 in an axial direction), and the quick release knob 82 may include a knob body 821 and a knob threaded portion 820 (e.g., an externally threaded post projecting axially from the knob body 821) complementary to the base threaded portion 810, wherein the loading base 81 and the quick release knob 82 may effect the releasable mating connection based on the threaded engagement of the base threaded portion 810 and the knob threaded portion 820.

Further, considering that the loading base 81 needs to be kept in a certain usage state posture during the dismounting process, the quick release mounting cylinder 72 forms a rotation stop restriction on the received loading base 81 to perform an operation of effecting or releasing the screw engagement based on an operation manner of rotation stop of the loading base 81 and screwing of the quick release knob 82, so that a convenient dismounting operation can be performed while keeping the portable device in the usage state posture.

In order to realize the rotation stop of the loading base 81 in the quick-release mounting barrel base 72, the outer periphery of the loading base 81 may have a locking protrusion 811, and the inner wall of the barrel cavity of the quick-release mounting barrel base 72 may have a locking slot 721, so that the loading base 81 may be restrained in the barrel cavity of the quick-release mounting barrel base 72 by the engagement of the locking protrusion 811 and the locking slot 721.

Moreover, the engagement of the locking protrusion 811 and the locking slot 721 not only can achieve rotation stopping, but also can further improve the stability of the engagement fit of the loading base 81 and the loading bracket 70.

That is, the quick-release knob 82 can be screwed on the quick-release assembly barrel seat 72, and the quick-release assembly barrel seat 72 can also form an axial anti-disengagement constraint on the quick-release knob 82, so that, in response to the gradual engagement of the base threaded portion 810 and the knob threaded portion 820, the loading base 81 moves axially towards the quick-release knob 82, and the axial movement can cause the formation of a wedge surface fit between the locking protrusion 811 and the locking slot 721, and the wedge surface fit is used for improving the tabling tightness of the locking protrusion 811 and the locking slot 721.

In order to realize the axial anti-drop restraint of the quick-release assembling cylinder seat 72 on the quick-release knob 82:

the quick release knob 82 may further include a mating barrel 822 extending axially from the knob body 821, and a retaining flange 823 protruding radially outward from an outer peripheral surface of the mating barrel 822, wherein the mating barrel 822 may surround an outer periphery of the knob threaded portion 820, and an outer diameter of the knob body 821 is larger than an outer envelope radial dimension of the retaining flange 823 protruding radially outward from the mating barrel 822;

the inner diameter of the cylinder cavity of the quick-release assembling cylinder base 72 can be smaller than the outer diameter of the knob main body 821 and larger than the outer enveloping radial dimension of the anti-drop flange 823, the inner wall of the cylinder cavity of the quick-release assembling cylinder base 72 can also be provided with a raised anti-drop convex tooth 722, and the inner enveloping radial dimension of the anti-drop convex tooth 722 is smaller than the outer enveloping radial dimension of the anti-drop flange 823.

Therefore, the quick release assembly barrel base 72 can form axial anti-release constraint on the quick release knob 82 through axial interference of the anti-release teeth 722 and the anti-release flange 823. When the quick-release knob 82 is first installed, the anti-release flange 823 is used for forcibly and axially extruding and deforming the anti-release teeth 722, so that the matching column barrel 822 is forcibly inserted into the barrel cavity of the quick-release assembling barrel base 72, and then the quick-release knob 82 can be maintained in a state of being threadably installed on the quick-release assembling barrel base 72 based on axial interference between the anti-release teeth 722 and the anti-release flange 823.

In the embodiment of the present application, the loading stand 70 of the loading mechanism may be selectable in the installation posture of the arch assembly 10 (e.g., the arch arm member 30) serving as the carrier, that is, the loading stand 70 may further include mounting adapter seats 73 formed on the stand body 71, for example, the quick-release fitting cylinder seats 72 and the mounting adapter cylinder seats 73 may be respectively located at opposite ends in the extending direction of the stand body 71.

The mounting adapter 73 may be used to mount the loading ledge 70 to the arch assembly 10 (e.g., the arch arm member 30) at a selected angle, for example, the mounting adapter 73 may be coaxially nested with the adjustment mounting socket 35 of the arch arm member 30.

In one example of an embodiment of the present application, the arch assembly 10 (e.g., the arch arm member 30) may have at least three mounting bosses 352 equiangularly distributed, in the illustrated representation of an embodiment of the present application, four mounting bosses 352 equiangularly distributed inside the wall of the adjustment mounting boss 35 are exemplified; the fitting cylinder base 73 may have mounting hole bases 730 equal in number and equiangularly distributed to the mounting base 352, and in the illustration of the embodiment of the present application, four mounting hole bases 730 equiangularly distributed to the inner wall of the cylinder cavity of the fitting cylinder base 73 is taken as an example.

Thus, the selected angle of the loading bracket 70 when the arch assembly 10 is installed may be determined by the selective mating of the mounting block 352 with the mounting socket 730.

Fig. 25 is a schematic view of the reversing principle of the loading mechanism of the head mount in the embodiment shown in fig. 1. Referring to fig. 25, in the present embodiment, the loading bracket 70 of the loading mechanism may be selectively mounted to any one of the pair of arm members 30 of the arch assembly 10, for example, the loading bracket 70 may be selectively mounted to the adjustment mounting boss 35 of any one of the pair of arm members 30 of the arch assembly 10, i.e., the loading direction change of the portable device may be implemented to accommodate the left and right hand operation habit of the wearer.

Referring back to fig. 1 and fig. 3a and 3b, if the loading bracket 70 is selectively mounted (e.g., coaxially mounted) on the adjustable mounting tube seat 35 of any one of the pair of arch arm members 30 of the arch assembly 10, the head mount in the embodiment of the present application may further include a decorative cover plate 90, wherein the mounting adapter 73 of the loading bracket 70 mounted on the mounting tube seat 35 of one side of the arch arm member 30 may be covered and decorated by the decorative cover plate 90, and the mounting tube seat 35 of the other side of the arch arm member 30, which is not mounted with the loading bracket 70, may also be covered and decorated by the decorative cover plate 90.

It will be appreciated that the loading mechanism including the loading bracket 70, the loading base 81 and the quick release knob 82 in the present embodiment may be applied to other carriers besides the head-mounted arch assembly 10.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
