Referring to fig. 1, 3, 5, 8 and 10, an embodiment of the present invention provides an adjustable wearable device, including a main housing 100 and two arm housings 200, wherein the two arm housings 200 are symmetrically attached to two ends of the main housing 100 through an angle adjusting mechanism, the angle adjusting mechanism includes a lock member 300 disposed in the main housing 100 and a linkage member 400 drivingly connected between the lock member 300 and the arm housings 200, and the lock member 300 includes a lock portion and a driving portion; the locking part is configured to cooperate with the main housing 100 to brake when no external force is applied, so that the locking member 300, the linkage member 400 connected with the locking member and the arm housing 200 are in a locking state; the driving part is configured to drive the locking part to be released from braking with the main housing 100 by the first external force so that the locking member 300 is in the unlocked state, and to drive the arm housing 200 to rotate relative to the main housing 100 by the second external force driving link member 400 to perform angle adjustment when the locking member 300 is in the unlocked state.

In practical application, on one hand, the driving part can conveniently control the linkage 400 to drive the arm shell 200 to rotate relative to the main shell 100, so that the arm shell 200 has a proper opening angle relative to the main shell 100, thereby meeting the requirements of different users on the size of the wearable device, and on the premise that the size of the wearable device is proper, the user can further finely adjust the opening angle of the arm shell 200 through the driving part, thereby correspondingly adjusting the clamping force applied by the arm shell 200 to the user, and improving the comfort level of the user; on the other hand, after the arm casing 200 is rotated to the position required by the user, by canceling all external forces acting on the driving part, the locking member 300 can be simultaneously returned to the locking state from the unlocking state, and the arm casing 200 and the main casing 100 are correspondingly locked, so that the wearing requirement of the user is met, the arm casing 200 can stably maintain the clamping force in the subsequent use process, the wearing stability and reliability are improved, and when the arm casing 200 is applied to computer wave acquisition equipment, the electrode sensor 600 can obtain accurate and reliable brain wave signals of the user, and a good effect is achieved; in addition, the driving portion has two functions of controlling locking/unlocking of the locking member 300 and adjusting the angle of the driving arm housing 200, and is compact in overall structure, thereby facilitating simplified operation and improving user experience.

In order to facilitate the assembling operation of the locking member 300 and the linkage member 400 in the main housing 100, the main housing 100 is preferably a split structure, and in particular, in this embodiment, the main housing 100 includes an upper housing 110 and a lower housing 120 that can be connected to each other in a snap-fit manner. The upper housing 110 and the lower housing 120 are each preferably arc-shaped housings to better conform to the skin of the user.

In addition, the main housing 100 may further include a hollow housing having a mounting hole for the locking member 300 and the linkage member 400 to be disposed in the hollow housing, and a cover capable of covering the hollow housing.

It should be noted that the adjustable wearable device can be applied not only to head-worn electronic devices such as brain wave acquisition devices and headphone devices, but also to arm-worn electronic devices.

As a preferred embodiment of the present invention, referring to fig. 1 to 3, 5 and 8 to 10, the driving portion is a lever 320, the lever 320 sequentially passes through a top wall of the main housing 100 (specifically, the upper housing 110 in this embodiment) and is connected to the locking portion and the linkage 400, respectively, the top wall of the main housing 100 is further provided with a sliding slot 111, the lever 320 can reciprocate along the sliding slot 111 by a second external force when the locking member 300 is in an unlocked state, and the linkage 400 is configured to correspondingly convert the reciprocating motion of the lever 320 along the sliding slot 111 into a forward or reverse rotational motion of the driving arm housing 200 reciprocating with respect to the main housing 100 within a set angle range. For convenience of description, the two ends of the sliding chute 111 are defined as a first end and a second end, the sliding of the operating lever 320 from the first end to the second end is defined as a forward movement, and the sliding of the operating lever 320 from the second end to the first end is defined as a reverse movement; the linkage 400 can convert the forward movement of the operation lever 320 into the forward rotation movement and further drive the arm housing 200 to rotate forward relative to the main housing 100 during the sliding of the operation lever 320 from the first end to the second end, and the linkage 400 can convert the reverse movement of the operation lever 320 into the reverse rotation movement and further drive the arm housing 200 to rotate backward relative to the main housing 100 during the sliding of the operation lever 320 from the second end to the first end. Specifically, in this embodiment, when the arm housing 200 rotates forward relative to the main housing 100, the wearing clamping force can be increased, and when the arm housing 200 rotates backward relative to the main housing 100, the wearing clamping force can be decreased. It should be understood that, depending on the structure of the linkage 400, it may be configured as follows: the arm housing 200 can be used to adjust the wearing clamping force when it rotates forward relative to the main housing 100, and can be used to adjust the wearing clamping force when it rotates backward relative to the main housing 100, without limitation.

The operating lever 320 is used as a driving part, so that the structure is simple, the driving part and the linkage member 400 can be conveniently installed in the main shell 100, and the convenience of product assembly and the improvement of appearance are improved; through the arrangement of the sliding groove 111, a reciprocating space is provided for the operating rod 320, and meanwhile, the reciprocating movement of the operating rod 320 can be limited, so that the rotation of the arm shell 200 relative to the main shell 100 is correspondingly limited within a set angle range, and therefore, when the arm shell 200 has a large adjusting range relative to the main shell 100, a large gap needs to be kept between the arm shell 200 and the main shell 100 when the arm shell 200 is attached to the end of the main shell 100, and the condition that the appearance is poor due to the fact that structural interference is easy to occur between the arm shell 200 and the main shell 100 in the adjusting process can be avoided; the reciprocating movement limit of the operating lever 320 can be in one-to-one correspondence with the rotation limit of the arm housing 200, so that the arm housing 200 and the main housing 100 are prevented from being damaged due to the transitional movement of the operating lever 320.

In some embodiments, the above-described linkage 400 may employ an existing slider linkage mechanism to convert reciprocating motion of the push rod relative to the main housing 100 into rotational motion of the swivel arm 212 relative to the main housing 100.

Referring to fig. 1, 3, 9 and 10, the link 400 includes a rack 410 connected to the operating lever 320, a gear 420 engaged with the rack 410, and a spline shaft 430 inserted into the gear 420 and engaged with the gear 420, and the arm housing 200 is connected to the spline shaft 430 through the rotation arm 212 provided therein. In this embodiment, the rotating arm 212 may be provided with a splined hole through which a splined shaft 430 is mounted to the arm housing 200 (specifically, the rotating arm housing 211 described below) after passing through the gear 420. The rack 410 can move synchronously with the operating lever 320 during the movement of the operating lever 320 along the sliding slot 111, and synchronously drive the gear 420 to rotate, so that the spline shaft 430 drives the rotating arm 212 and the arm housing 200 connected with the rotating arm to rotate relative to the main housing 100. Through the two-stage transmission structure design of the rack 410 and the gear 420 and the spline shaft 430, not only can the optimized transmission ratio be achieved to facilitate better control angle adjustment, but also the convenience of assembling the operating lever 320 and the linkage member 400 in the limited space of the main housing 100 can be improved, thereby further optimizing the overall structure design.

As a preferred embodiment of the present invention, referring to fig. 1 to 3, 6, 7 and 9, the locking portion includes: two first elastic blocks 11, wherein the two first elastic blocks 11 are respectively arranged in two opposite side walls of the main shell 100; the first elastic elements 12 are arranged between the two first elastic blocks 11 at intervals along the X-axis direction, and can press the side walls of the two first elastic blocks 11 against the corresponding side walls of the main housing 100 to brake when no external force acts, so that the locking member 300, the linkage member 400 connected with the locking member and the arm housing 200 are in a locked state; the driving portion is disposed through the middle of the first elastic element 12, and applies a first external force to the middle of the first elastic element 12 in the longitudinal direction, so that the two first elastic blocks 11 move toward each other in a direction away from the side wall of the main housing 100 to release the braking. With such a structure, on one hand, the first elastic element 12 can conveniently make the locking member 300 and the main housing 100 cooperate and abut against each other by preset elastic force to brake, and on the other hand, the unlocking of the locking member 300 by the driving portion is also simple, taking the operating lever 320 as an example, only a longitudinal force (i.e., a force in the Y-axis direction) needs to be applied to the end portion of the operating lever 320 that penetrates through the main housing 100, for example, by pressing the operating lever 320 or pulling out the operating lever 320, the middle portion of the first elastic element 12 can be longitudinally displaced, and both ends of the first elastic element 12 correspondingly contract toward the middle portion, so that the abutting acting force between the two first elastic blocks 11 and the main housing 100 is cancelled to release the braking, which is beneficial to further simplifying the structure of the whole locking.

As a preferred embodiment of the present invention, referring to fig. 1 to 3, 6, 7 and 9, the locking part may further include: two second elastic blocks 13, wherein the two second elastic blocks 13 are respectively arranged in two opposite side walls of the main shell 100; the second elastic element 14, the second elastic element 14 is transversely arranged between the two second elastic blocks 13, and can press the side walls of the two second elastic blocks 13 against the corresponding side walls of the main casing 100 to brake when no external force acts; the driving part is arranged in the middle of the second elastic element 14 in a penetrating way, and a first external force is longitudinally applied to the middle of the second elastic element 14 so as to enable the two second elastic blocks 13 to move towards each other in a direction of separating from the side wall of the main shell 100 and release braking; wherein the second spring block 13 and the second elastic element 14 are arranged at a longitudinal (i.e. Y-axial) interval with respect to the first spring block 11 and the first elastic element 12. Through setting up second bullet piece 13 and second elastic element 14, can further improve the locking force between lock piece 300 and the main casing 100, ensure that lock piece 300 and even whole wearing device have better self-locking performance when no exogenic action, when being applied to brain wave collection equipment, especially when this wearing device is applied to computer wave collection equipment, be favorable to improving the reliability of the user's brain wave signal that electrode sensor 600 obtained more. The second elastic block 13 is further preferably arranged in parallel with the first elastic block 11, and the second elastic element 14 is preferably arranged in parallel with respect to the first elastic element 12, so as to improve the stability and reliability when the locking part is tightly matched with the main housing 100.

The third elastic element 15 is arranged to tightly abut against three sides of the main housing 100 with the first elastic element 12 (and/or the second elastic element 14), so as to further improve the self-locking performance of the locking member 300 and the main housing 100 when no external force acts.

As a preferred embodiment of the present invention, referring to fig. 2, 7 and 9, the first elastic element 12 includes a first elastic band 1a, a second elastic band 2a and a third elastic band 3a which are sequentially provided at intervals in the X-axis direction, and the driving portion is inserted into the second elastic band 2 a. Such a structure is not only beneficial to increasing the abutting force between the first elastic block 11 and the main housing 100, but also enables the abutting force to be uniformly distributed on the side wall of the first elastic block 11, thereby further improving the self-locking effect.

As a preferred embodiment of the present invention, referring to fig. 2, 7 and 9, the locking portion further includes a first link 4a and a second link 5a, the first elastic band 1a is sleeved on the first link 4a, the third elastic band 3a is sleeved on the second link 5a, one of the first elastic blocks 11 is disposed at the same end of the first link 4a and the second link 5a, the other first elastic block 11 is disposed at the other end of the first link 4a and the second link 5a, and the two first elastic blocks 11 can slide along the axial direction of the first link 4a and the second link 5a under the action of the first elastic element 12. During the process of releasing the brake, the two first elastic blocks 11 can move towards each other on the first link 4a and the second link 5a, and during the process of restoring the brake, the two first elastic blocks 11 can move in opposite directions on the first link 4a and the second link 5 a. The arrangement of the first connecting rod 4a and the second connecting rod 5a can play a good role in positioning and guiding the two first elastic blocks 11 and the corresponding first elastic belts 1a and third elastic belts 3a, so that the flexibility and reliability of switching the first elastic blocks 11 between braking and brake release are improved, and the situation that the first elastic belts 1a and the third elastic belts 3a cannot provide transverse preset elastic force which can be abutted against the main shell 100 to the first elastic blocks 11 due to longitudinal deformation caused by long-term use and then self-locking failure occurs can be avoided; in addition, the arrangement of the first link 4a and the second link 5a is also beneficial to improving the structural reliability and stability of the whole locking member 300.
