Referring to fig. 1, in order to satisfy the structural schematic diagram of the fixing assembly 100 in a preferred embodiment of the present invention, in this embodiment, the fixing assembly 100 is used to fix two devices, such as a wearable device 300 and an external device (e.g., an expansion module) cooperating with the wearable device 300, wherein the fixing assembly 100 includes a fixing element 110 and a fitting element 120, wherein the fixing element 110 is connected to the external device, such as the wearable device 300, the fitting element 120 is connected to the external module, such as an infrared thermal imaging module, a laser module, etc., and then the fixing element 110 is fixed to the fitting element 120, so as to fix the wearable device 300 and the external device to each other. In addition, the engaging element 120 is not in the only limited position on the fixing element 110, but the engaging element 120 can rotate on the fixing element 110, so that the external device can rotate relative to the wearable device 300 to adjust the position.

To achieve the quick installation and accurate adjustment of the fixing member 110 and the engaging member 120, the fixing member 110 includes:

-a fixed body 111

The fixing body 111 forms a main body of the fixing member 110, and mainly serves as a fixing portion for providing attachment of the fixing member 110 to an external device such as the wearable device 300. For example, the fixing body 111 may be mounted to, locked with, bonded to, sleeved with, clamped with, welded to, etc. an external device.

-a resilient element 112

The fixed end of the elastic member 112 is connected to the fixed body 111, and the free end thereof extends toward the fitting member 120 and has a mounting shaft fitted with the fitting member 120. It is understood that the mounting shaft is a mechanical shaft formed by the elastic element 112, and may be a solid shaft structure, a virtual shaft illustration, or the elastic element 122 itself may be formed as the whole mounting shaft. Taking the elastic element 122 itself as an example of forming the mounting shaft, after the elastic element 122 is formed, it is integrally snapped into the fitting element 120 and rotates in the fitting element 120, and the limit in the fitting element 120 is realized by the elastic force of the elastic element 122, so that the elastic element 122 not only guides the mounting direction of the fitting element 120 and the fixing element 110, but also serves as a mounting shaft to position the fixing element 110 and the fitting element 120 relatively; taking a solid shaft structure as an example, the mounting shaft may be a long-strip shaft structure extending outward from the middle of the elastic element 122; under a virtual mounting shaft, the axis of symmetry or axial direction formed by the mechanical structure of the elastic element 122 is the mounting shaft. Due to the characteristics of the elastic element 112, such as plastic material, elastic plastic, etc., when the elastic element 112 is subjected to an external force, the elastic element 112 will deform according to the direction of the force. It is understood that the elastic element 112 may be formed separately or integrally with the fixing body 111, i.e. the fixing body 111 may be made of the same material as the elastic element 112.

In contrast, the fitting 120 includes:

-a mating body 121

The fitting body 121 forms a main body of the fitting 120, and mainly serves to provide a fixing portion for mounting the fitting 120 to an external device such as an infrared module, a laser module, or the like. For example, the expansion module may be bound to the mating body 121, or bonded, sleeved, clamped, welded, etc. to the mating body 121.

Mounting element 122

The fixed end of the mounting element 122 is connected to the mating body 121, the free end thereof extends toward the fixing member 110, and the mounting element 122 is further configured such that the mounting element 122 is hollow to form a fixing space, and a mounting shaft hole is provided in a direction of the mounting element 122 facing the elastic member 112, the mounting shaft hole being a part of the body of the mounting element 122 and may be formed in a shaft sleeve type, a shaft hole type, or the like.

Preferably, the mounting shaft hole of the mounting element 122 faces the elastic element 112 and is provided with an opening 123, and it is understood that the opening 123 may be a hollowed-out portion on the mounting shaft hole. After the above configuration, the mounting element 122 is moved toward the elastic element 112 on the straight line where the extending direction of the elastic element 112 is located, that is, the user can hold the mounting element 122 by hand to move toward the elastic element 112 until the mounting shaft hole of the mounting element 122 contacts with the elastic element 112, both ends of the opening 123 of the mounting element 122 will abut against the free end of the elastic element 112, the free end of the elastic element 112 is deformed after being stressed, because both ends of the opening 123 are the bodies of the mounting shaft hole of the mounting element 122, the opening 123 is hollow, the elastic element 112 can only be deformed to the structure of being snapped into the opening 123, that is, the opening 123 presses the elastic element 112, so that the elastic element 112 can be snapped into the mounting element 122, after the elastic element 112 is filled into the mounting shaft hole of the mounting element 122, the inner wall of the mounting shaft hole of the mounting element 122 will coat the outer surface of the elastic element 112, therefore, the mounting shaft of the elastic element 112 is engaged with the shaft hole of the mounting element 122, and since the free end of the elastic element 112 is separated from the opening 123, the elastic element 112 is fed back to the initial state or is fed back to deform as much as possible according to the self-stress until the outer surface of the elastic element 112 abuts against the inner wall of the mounting shaft hole of the mounting element 122, and since only contact damping exists between the elastic element 112 and the mounting element 122, the elastic element 112 and the mounting element 122 can displace along the contact part, so that the installer 122 and the elastic element 112 can rotate relatively.

Further, it is preferable or optional that the opening 123 of the mounting shaft hole is configured such that the size of the opening 123 is larger than the fixed end of the elastic element 112, but is optionally smaller than the free end of the elastic element 112, so that the free end of the elastic element 112 cannot be pulled out from the mounting shaft hole 2 without being subjected to an external force, and the opening 123 can move around the outer surface of the elastic element 112, specifically, both ends of the opening 123 are not closed, and the elastic element 112 does not fully extend into the mounting shaft hole, and the non-extending portion (up to the fixing element 110) is still exposed out of the mounting shaft hole, so that both ends of the opening 123 can rotate around the surface of the elastic element 112 until contacting with the fixing element 110, that is, the non-extending portion provides the mounting shaft hole with a rotational displacement around the elastic element 112, thereby realizing a positional change between the fixing element 110 and the mating element 120, when a user needs to move the external device relative to the wearable device 300 in the X-axis or Y, this is accomplished by rotating the fixing member 110 and the engaging member 120.

Referring to fig. 2, in a preferred embodiment, the elastic element 112 of the fixing member 110 includes:

base unit 113

The fixed end of the base unit 113 is connected with the fixed body 111, and the free end extends toward the fitting 120. The base unit 113 may be one or more, or a plurality of base units 113 may be interconnected to form a base assembly. The base unit 113 may be made of a material with a low deformation force, and remains substantially stationary when subjected to a force to maintain a partial position of the elastic member 112.

-elastic leg clip 114

The fixed end of the elastic leg clip 114 is connected to the base unit 113 (or extends from the free end of the base unit 113), and the elastic leg clip 114 is in an arc shape away from the axial direction of the elastic element 112, that is, the width of the elastic leg clip 114 is gradually increased (or gradually increased and then gradually decreased) in the direction from the base unit 113 to the elastic leg clip 114.

When elasticity leg clamp 114 touches the both ends of opening 123, opening 123 both ends extrusion elasticity leg clamp 114's free end, with elasticity leg clamp 114 along self radial inwards shrink, along with the continuation motion of installation component 122, elasticity leg clamp 114 stretches into the inside of installation component 122 gradually, and when the free end of elasticity leg clamp 114 touched the inner wall top to installation component 122, because the restriction at inner wall top, elasticity leg clamp 114 can't continue to stretch into, and because the setting of fixed space, the part of former elasticity leg clamp 114 inwards shrink is according to self stress, kick-back until with the both sides inner wall contact of installation component 122, realize that elasticity leg clamp 114 fills the fixed space promptly, and can understand, the fixed space can set up to: compared with the original state of the elastic leg clip 114, the size of the elastic leg clip 114 is smaller, so that the elastic leg clip 114 does not rebound to the original state after filling the fixing space, and is still in the state of releasing the elastic force, so that the inner wall of the mounting element 122 and the outer surface of the elastic leg clip 114 have the interactive elastic force, the larger the elastic force is, the larger the friction force between each other is, and the fitting relationship between the mounting element 122 and the elastic leg clip 114 is firmer. Further, it is understood that the top of the inner wall of the mounting element 122 can limit the displacement of the elastic element 112 in the extending direction thereof, and once the elastic leg clip 114 is inserted into the fixing space, the elastic leg clip 114 cannot move upward (or in the extending direction thereof), leftward and rightward (or in the direction perpendicular to the extending direction thereof) except for the opening 123 in the circumferential direction of the surface of the elastic leg clip 114, so as to allow the fixing member 110 to be firmly engaged with the engaging member 120.

Referring to fig. 3, in order to cooperate with the elastic element 112 in the above embodiment, the installation shaft hole may be specifically configured or include:

snap ring 124

In this embodiment, the mounting shaft hole is formed as a snap ring 124, connected to the mating body 121, and extending in a direction perpendicular to the extending direction of the elastic element 112, that is, the snap ring 124 may be a main body of the mounting element 122, and the inside thereof is hollow to form the fixing space. The snap ring 124 protrudes from the fitting body 121, so that when the mounting element 122 is fitted with the elastic element 112, the fitting body 121 will not interfere with the movement of the mounting element 122 in the mounting direction.

In addition, the extension length of the snap ring 124 is equal to, or substantially equal to, the thickness of the elastic leg clip 114, after the elastic leg clip 114 is inserted into the fixing space, one side of the elastic leg clip 114 in the radial direction (i.e. the direction perpendicular to the extension direction of the snap ring) is limited by the fitting body 121, and two cut-off portions of the snap ring 124 form an opening 123, i.e. two end portions of the snap ring 124 are not completely closed, and the position and size between the two end portions will determine the size of the opening 123.

Cover 125

The cover 125 is disposed at the free end of the snap ring 124, and closes the end of the snap ring 124 away from the engaging body 121, so that the elastic leg clip 114 is limited by the cover 125 at the other side of the radial direction, and then the thickness of the elastic leg clip 114 is substantially equal to the extending length of the snap ring 124, so that the elastic leg clip 114 is further limited in the fixing space in the direction perpendicular to the extending direction of the elastic element 112.

It is understood that the cover 125 can be the free end of the fully closed snap ring 124, or the free end of the semi-closed snap ring 124, i.e. the middle of the cover 125 is hollowed out to ensure that the elastic leg clip 114 contacts with the part of the cover 125 to limit the position, and the cover can be integrally formed with the mounting shaft hole or assembled to form the complete mounting element 122.

Referring to fig. 4-5, the clamping ring 124 has a through hole 126 formed on each of two sides of a symmetry axis, i.e., a mounting axis, which may be an axial direction in a vertical direction of the clamping ring 124 in the cross-sectional direction of the fixing element 110 or a direction parallel to the surface of the mounting element 122 as a central axis, and at least a portion of the clamping ring 124 is cut out on each side thereof, so that the clamping ring 124 does not have a continuous curved surface or the clamping ring 124 does not have a continuous curved surface (both sides of the cut-out portion have a continuous curved surface). The through hole 126 is disposed such that when the elastic leg clip 114 is limited in the inner portion of the snap ring 124, a portion of the elastic leg clip 114 facing the through hole 126 faces outward, and a user can insert a finger from the outer portion of the snap ring 124 through the through hole 126 to abut against the elastic leg clip 114, and then passively deform the elastic leg clip 114 in the fixing space, specifically, shrink toward the central axis until the width is smaller than the opening 123, and then the user can hold the snap ring 124 again and pull out the engaging element 120 from the fixing element 110 in a direction away from the elastic element 112. That is, through the provision of the through-hole 126, the user can more easily detach the fitting member 120 from the fixing member 110. In addition, the through hole 126 provides a space for the elastic element 112 to deform outwards, and the elastic element 112 can partially expose the through hole 126 according to the self-stress, so that the contact force between the unexposed part of the elastic element 112 and the snap ring 124 is further increased, and the fixed sliding between the elastic element 112 and the mounting element 122 is prevented.

Preferably or alternatively, the elastic leg clip 114 comprises a pair of leg clip units, each leg clip unit being disposed on either side of the axis of symmetry of the elastic member 112 such that the stresses on the outward sides of the elastic member 112 are the same or substantially the same. The free ends of the two leg clip units are separated to form a deformation redundancy distance, and when the leg clip units contact the opening 123, the free ends of the leg clip units contract inwards, i.e. the deformation redundancy distance is shortened (the free ends of the leg clip units can be close to, contact or staggered), so that the situation that when the opening 123 is too small, the elastic element 112 contracts too much to cause fracture or the elastic force disappears is prevented.

In another preferred or alternative embodiment, the free ends of the leg clamp units are connected by a resilient connection, such as a spring, etc., to ensure that the resilient leg clamps 114 do not separate excessively when the resilient leg clamps 114 are not extended into the mounting elements 122, on the one hand, and to provide a counter-directed spring force to the resilient leg clamps 114 when the resilient leg clamps 114 are extended into the mounting elements 122, on the other hand, to further increase the contact force between the resilient leg clamps 114 and the mounting elements 122.

In a further preferred or alternative embodiment, a gimbaled ball is fixed in the leg clamp unit, for example squeezed into the leg clamp unit from a separation space at the free end of the leg clamp unit. To ensure that the gimballed body does not come out of the leg clip unit, the diameter of the gimballed body is larger than the radial width of the leg clip unit, in that the gimballed body can only be restricted from universal rotation within the leg clip unit, and optionally the diameter of the gimballed body can be configured to have an interference fit with the leg clip unit after being placed within the leg clip unit, the leg clip unit having been slightly distracted by the gimballed body creating an outwardly facing stress when the resilient leg clip 114 is not extended into the mounting element 122. The inner wall of the mounting element 122 is spherical corresponding to the universal ball, that is, the end surface of the fitting body 121 disposed in the mounting element 122 is curved, and the cover 125 is also curved, so that when the mounting element 122 rotates around the elastic element 112, the universal ball provides universal rotation to the mounting element 122, thereby further increasing the adjustment angle of the fitting 120.

In yet another alternative or preferred embodiment, the curvature of the resilient leg clip 114 is substantially the same as the curvature of the snap ring 124, such that when the resilient leg clip 114 is stabilized within the mounting member 122, the inner wall of the snap ring 124 substantially conforms to the outer curved surface of the resilient leg clip 114, thereby increasing the contact area and reducing the pressure therebetween to prevent the resilient leg clip 114 from being excessively deformed. On the other hand, when the snap ring 124 is arc-shaped, after the elastic element 112 is snapped into the mounting element 122, the center of the circle of the elastic leg clip 114 is lowered accordingly when the elastic leg clip 114 is retracted inward, and just after the elastic leg clip 114 is retracted to a stable position after being completely snapped into the mounting element 122, the center of the circle of the snap ring 124 coincides with the center of the circle of the elastic leg clip 114 which is also arc-shaped, so that the automatic centering of the elastic leg clip 114 and the snap ring is completed. Under such a configuration, when the elastic leg clamp 114 is engaged with the engaging ring 124, the elastic leg clamp 114 is engaged with the engaging ring through the shaft hole, and when the elastic leg clamp 114 and the engaging ring 124 are relatively rotated, the elastic leg clamp and the engaging ring rotate around the same center of circle, a radial pre-pressing deformation interference amount is designed between the respective shaft and the hole, and the elastic leg clamp 114 stops the engaging ring 123 at a certain relative position after the elastic leg clamp and the engaging ring rotate due to the action of the radial pre-pressing deformation interference amount after the elastic leg clamp and the engaging ring rotate at any position. Specifically, taking the sectional view as an example, the circle centers of the portions of the snap ring 124 located at the two sides of the elastic leg clip 114 coincide with the circle center of the elastic leg clip 114 at the same point or are located on the same horizontal line. When the clamping ring 124 rotates clockwise around the elastic leg clamp 114, the portion of the clamping ring 124 located at the left side rotates (upward) along the outer surface of the elastic leg clamp 114 with its center as the center of rotation, the portion of the clamping ring 124 located at the right side rotates (downward) along the outer surface of the elastic leg clamp 114 with its center as the center of rotation, the portion of the clamping ring 124 located at the upper side rotates (upward) along the outer surface of the elastic leg clamp 114 with its center different from the centers of rotation of the two side portions, and at the same time, the elastic leg clamp 114 is pressed by the clamping rings 124 at both sides and deforms inward, because its center is higher than the centers of the clamping rings 124 at both sides, so that the clamping ring 124 located at the upper side will contract inward rather than taking its center as the center of rotation, and at the same time, the clamping ring 124 located at the upper side still rotates around its center, so that when the clamping ring 124 rotates back to the original position, the rotation path of the clamping ring 124 will not interfere with the rebound path of the elastic, i.e., without the upper snap ring 124 portion folding the free end of the elastic leg clip 114 outward or even breaking. Meanwhile, by means of the self-centering of the elastic leg clip 114 and the mounting element 122, when the elastic leg clip 114 is in a stable position after being clamped into the mounting element 122, the outer surface of the elastic leg clip 114 and the inner surface of the mounting element 122 are almost free from gaps, and by means of the self-stress of the elastic leg clip 114 (the direction is along the outward radial direction of the elastic leg clip 114), a damping between the elastic leg clip 114 and the snap ring 124 is formed, and the damping helps the snap ring 124 not to move any more when rotating to a certain position along with the operation of a user, so that a fixing effect is achieved.

Further preferably or alternatively, the fixing body 111 has a hollow portion facing the extending direction of the elastic element 112 to form a movable space for an installer to fit to the elastic element 112, on one hand, the material of the fixing body 111 can be saved, on the other hand, since the mounting element 122 needs to move towards the elastic element 112 in this direction, if the portion of the fixing body 111 is closed and the mounting element 122 is fitted to the elastic element 112, the mounting element 122 needs to be firstly placed under the closed portion from the side, and then moved downwards to insert the elastic element 112 into the mounting element 122, and the difference between the placing direction and the inserting direction increases the mounting process. After the installation element 122 is hollowed out, a user can directly insert and detach the installation element 122 in one direction, the installation and detachment are convenient, and meanwhile, the space of the hollowed-out part can be further increased to enable the fixing body 111 to be in a V-shaped structure with the wide top and the narrow bottom, so that more spaces are provided for more convenient installation of the installation shaft hole of the distribution installation element 122 and the installation shaft of the elastic element 112.

Referring to fig. 6, in this embodiment, the fitting 120 further includes a frame 127 serving as a portion for connecting with an external device or an external module 200, on which the external module 200 is fixedly mounted, and the connection with the external module 200 may be a screw connection, a rivet connection, a magnetic attachment, or the like. The connection between the frame 127 and the mating body 121 is provided with a hinge element, such as a hinge, whose axial direction is crossed or opposite to the axial direction of the elastic element 112, and more preferably, the extending direction of the hinge element is parallel to the extending direction of the elastic element 112, so that the frame 127 can rotate around the radial direction of the elastic element 112, and the mounting element 122 rotates around the outer surface of the elastic element 112, and when a user needs to finely adjust the position of the external module 200, the adjustment direction is more abundant.

In other embodiments, not shown, the connection point of the frame body 127 and the mating body 121 is not hinged as in the above embodiments, but is matched with the shaft hole of the elastic element 112 and the mounting element 122, that is, the frame body 127 is provided with an elastic structure like the elastic element 112, and the mating body is further provided with a mounting shaft hole structure like the mounting element 122, so that after the frame body is matched with the shaft hole of the mating body 121, the frame body 127 can still rotate around the elastic element 112 in the axial and radial directions. It can be understood that the shaft hole matching structures of the frame 127 and the matching body 121 are interchangeable, that is, the frame 127 is provided with a mounting shaft hole structure like the mounting element 122, and the matching body 121 is provided with an elastic structure like the elastic element 122.

Other configurations of the resilient member 112, such as providing chamfers and protrusions on the free ends of the resilient leg clips 114, help to make the resilient member 112 more easily inserted into the mounting member 122, and make the resilient member 112 less likely to be removed from the mounting member 122 after insertion into the mounting member 122. The rotatable position of the snap ring 124 on the resilient leg clip 114, again, ends at the base unit 113 such that the rotation angle of the mounting element 122 is between 0-20 deg., preferably between 0-10 deg., clockwise and counterclockwise. If the two leg clamp units of the elastic leg clamp 114 are asymmetric, the elastic leg clamp 114 on one side has a higher extension height and the other side has a lower extension height, the inner end surface of the leg clamp unit with the higher extension height is provided with a groove, the outer end surface of the leg clamp unit with the lower extension height is provided with a protrusion, the protrusion is inserted into the groove and slides along the guide of the groove, when the elastic leg clamp 114 is stressed, the leg clamp units contract relatively, the protrusion slides to the root of the groove, and when the stress of the elastic leg clamp 114 is released, the protrusion slides to the head of the groove, and the groove limits the protrusion, thereby preventing the leg clamp units from separating too much. The optional or preferred configurations can be added or adjusted according to the actual application scene of the user.

In another alternative embodiment, the positions of the resilient element on the fixing element and the mounting element on the counterpart may be interchanged, i.e. the fixing element is provided with the mounting element and the counterpart with the resilient element. Specifically, in this embodiment, the fixing assembly also includes a fixing element and a fitting element, the fitting element is mounted to the fixing element and can rotate on the fixing element, the fixing element includes: a fixing body providing a fixing part for mounting the fixing member to an external device; the mounting element is connected to the fixed body, is provided with a mounting shaft hole facing the matching piece and is mounted with the matching piece in a matching way; correspondingly, the fitting comprises: a fitting body providing a fitting portion for mounting the fitting to an external module; the elastic element is connected to the matching body and is provided with a mounting shaft matched and mounted with the mounting element; the elastic element can deform and is clamped with the mounting shaft hole, so that the elastic element is matched with the mounting shaft hole, and the mounting element and the elastic element rotate relatively.

Referring to fig. 7 to 9, after having the fixing assembly 100 according to any of the embodiments, the fixing assembly can be applied to a wearable device 300, such as smart glasses, a smart watch, a smart arm, a head-mounted device, and the wearable device 300 includes a device body, and in order to expand the external module 200, a fixing body 111, such as a glasses earpiece of the smart glasses, a wrist strap of the smart watch, an arm strap of the smart arm, and a strap of the head-mounted device, is clipped on a bracket 310 of the device body. To mount the fixing body 111 on the wearable device 300, the fixing body 111 includes a pair of clamping leg clips, and the distance between the clamping leg clips is substantially equal to or slightly less than the width of the bracket 310, so as to facilitate the user to mount the fixing member 110 on the wearable device 300 quickly. Preferably, the length of the upper clamping leg clip is greater than the length of the lower clamping leg clip, the upper clamping leg clip provides a larger contact area to prevent dropping when subjected to gravity, and the lower clamping leg clip provides a smaller contact area for the user to more easily remove the installed fixture 110 from the wearable device 300. On the side of the fitting member 120, the external module 200 is installed, i.e. the wearable device 300 is added with additional auxiliary functions of the external module 200.
