In one example, two signal output terminals V + and V-of the control module 3 are used to output the motor control signal. When the signal output by the V + end is a first signal, the signal is used for controlling the motor to rotate forwards so as to enable the two telescopic arms 11 to move relatively and tighten the head-mounted equipment support; when the signal output by the V-end is a second signal, the two telescopic arms 11 move back to back, and the head-mounted equipment support is loosened.

In this application, control module 3 can be solitary MCU, singlechip, also can be the main control chip of wear-type equipment. The control module 3 may send control signals to control the forward and reverse rotation of the motor. In this application, control module 3 with the tight regulation mechanism electricity is connected, according to adjusting signal, controls tight regulation mechanism 2 drives flexible arm motion, so that flexible length by initial length extension or retraction to target length.

The length of the telescopic arm 11 is understood to be the length of the telescopic arm 11 which contributes to the telescopic arm 11 in the ring shape enclosed by the telescopic arm and the front shell. The initial length of the telescopic arm 11 may be arbitrary. The target length of the telescopic arm 11 is understood here to be the length of the telescopic arm adapted to the head size of the user, which may be equal to the initial length of the telescopic arm 11.

The control module 3 is used for receiving the adjusting signal. The source of the conditioning signal can take at least three forms. The source of the modulating signal can take at least three forms:

in one embodiment, a button is disposed on the bracket body 1, and a user can press the button to send an adjusting signal for adjusting the size of the telescopic arm 111 to the slack adjuster 2.

In another embodiment, the control module 3 has a memory unit and a detection unit, the detection unit is used for confirming the identity of the user, and the memory unit can store the head circumference size of the user, so that after the detection unit confirms the identity of the user, the memory unit can call the related information of the user to generate an adjustment signal, so that the length of the telescopic arm adjusted by the tightness adjusting mechanism can exactly match the head size of the user. The detection unit may be a face recognition unit or a fingerprint recognition unit.

In another embodiment, the head-mounted device support further includes a pressure sensor, which may be disposed on the housing assembly 4 or the telescopic arm 11, and when the user wears the head-mounted device, the pressure sensor may directly or indirectly sense the pressure, and when the pressure reaches a certain level, the pressure sensor is triggered to send a signal to the control module 3, so that the control circuit 3 controls the slack adjuster to stop working.

In another embodiment, the head-mounted device stand further comprises a first switch 43 and a force-receiving member 5, wherein the first switch 43 is used for connecting or disconnecting the electrical connection path between the control module 3 and the slack adjuster mechanism 2; the force-receiving member 5 has a moving state and an initial state, when the force-receiving member 5 is in the moving state under the action of an external force, the force-receiving member 5 can contact with the first switch 43 to disconnect the electric connection path, and the length of the telescopic arm 11 is at the target length; when the stressed member is in the initial state, a gap exists between the stressed member 5 and the first switch 43, and the electric connection path is conducted.

Referring to fig. 3 and 4, fig. 3 is a structural schematic diagram of an assembly structure of the pressure receiving member and the front shell in fig. 1 at a viewing angle; fig. 4 is a cross-sectional view of the structure of fig. 3. The first switch 43 may have various forms, and in an embodiment, the first switch 43 includes a first metal sheet 431 and a first elastic member 432 disposed on the housing, the first metal sheet 431 and the first elastic member 432 are connected in series between the control module 3 and the slack adjuster 2, and the first metal sheet 431 and the first elastic member 432 are overlapped and electrically connected.

In one example, the first metal sheet 431 is provided at the front side of the power supply case. The first metal sheet 431 is substantially arc-shaped, one end of which is connected to the power supply housing, and the other end of which is used for being overlapped with the first elastic member 432. The first elastic member 432 includes a first elastic sheet, one end of the first elastic sheet is connected to the power supply housing, and the other end of the first elastic sheet is overlapped with the inner side of the first metal sheet 431.

For example, the control module 3V + end may be connected to the first elastic member 432 by a flat cable or a metal wire, and the first metal sheet 431 is electrically connected to the input end of the driving circuit 221, so that when the first elastic member 432 is electrically connected to the first metal sheet 431, the first control signal output by the control module 3V + end can be output to the driving circuit 221, thereby enabling the motor to normally operate. Therefore, when the first elastic piece is separated from the first metal piece 431, the first control signal output from the 3V + end of the control module cannot be output to the driving circuit 221, so that the motor stops working, and the two telescopic arms 11 stop moving relatively.

The force receiving member 5 shown in fig. 1 to 3 includes an elastic pad 51 and an ejector 52 provided on the elastic pad 51; the force-bearing part 5 is connected with the shell assembly 4, the elastic pad 51 is contacted with the head of a user, and the pushing part 52 extends along the thickness direction of the elastic pad 51 and is arranged corresponding to the first elastic part 432; when the elastic pad 51 is deformed to a certain degree, the pushing member 52 can push the first elastic member 432 to separate from the first metal sheet 431, so as to cut off the transmission path of the first control signal.

In one example, the elastic pad 51 is a soft pad. The cushion can correspond to the position of the back of the head of the user, and the force-bearing member 5 can further include a fixing plate on which the cushion is wrapped, and the shape of the fixing plate is matched with the shape and size of the first power supply shell 411 of the front shell 41 of the housing component 4. The force-bearing part 5 can be fixed on the housing component 4 by means of a snap fit or can be glued to the housing component 4 by means of glue.

The ejector 52 is disposed in the elastic pad 51. Specifically, in one embodiment, the cushion has a leather sheath and a soft material, such as sponge, filled in the leather sheath. The elastic pad 51 is provided with an installation groove 511, the bottom of the installation groove 511 can be a leather sheath, and the opening of the installation groove 511 faces the first elastic element 432. In order to match the shape of the cushion, the bottom of the mounting groove 511 may be provided in an arc shape.

The ejector 52 comprises a supporting piece 521 and an ejector pin 522 arranged on the supporting piece 521, and the supporting piece 521 is attached to the bottom of the mounting groove 511 to increase the contact area with the elastic pad 51. The thimble 522 extends toward the opening of the mounting slot 511.

Correspondingly, the front shell 41 is provided with a yielding hole 4111; the first elastic member 432 overlaps the first metal sheet 431 at a position opposite to the side of the offset hole 4111. When the first elastic member 432 is pushed by the pushing member 52, the first elastic member 432 can move toward the relief hole 4111 to disengage the first metal sheet 431, thereby electrically disconnecting the first metal sheet 431 from the first elastic member 432.

When the user wears the head-mounted device, the head of the user gradually presses the elastic pad 51 while the holder body 1 is continuously tightened with the control of the adjusting gear 21 by the slack adjusting mechanism 2, so that the elastic pad 51 is compressed in the thickness direction. It is understood that the greater the degree of tightening of the holder body 1, the greater the degree of compression of the elastic pad 51 in the thickness direction. Meanwhile, when the elastic pad 51 is compressed in the thickness direction, the supporting piece 521 is displaced in the thickness direction of the elastic pad 51, so that the thimble 522 gradually moves toward the first elastic piece 432. When the pressure that user's head received reached a certain degree, the comfort level that the user wore was just, can contact and promote first elastic component 432 corresponding to thimble 522 this moment for first elastic component 432 breaks away from with first sheetmetal 431, thereby cut off the transmission path of first control signal, make the motor of elasticity adjustment mechanism 2 stop working, and the size of support main part 1 keeps at current position, therefore this embodiment has realized according to the comfort level of wearing, with the mesh of automatically regulated support main part 1's size.

It can be understood that the length of the thimble 522 can be designed according to the degree of compression of the cushion in the thickness direction when the user feels comfortable; so that when the size of the bracket main body 1 is adjusted, once the degree of compression of the cushion reaches a certain degree, the thimble 522 just can move to a position capable of pushing the first elastic member 432 to be separated from the first metal sheet 431.

In the above embodiment, the elastic pad 51 is disposed on the front shell 41, and in other embodiments, the elastic pad 51 may be directly connected to the stand main body 1 and located inside the stand main body 1 for the head of the user to contact.

The first switch 43 in the above embodiment may also be two movably connected metal sheets, the pushing member 52 is an insulating sheet, and the pushing member 52 may extend into between the two metal sheets to break the electrical connection between the two metal sheets. The first switch 43 may also be a switch circuit with a button that is activated by the ejector 52 to open the switch circuit.

In summary, the pushing member 52 is disposed on the elastic pad 51, and the first metal sheet 431 and the first elastic member 432 are disposed on the housing assembly 4. In the wearing process, the overlapping size of the two telescopic arms 11 is automatically adjusted through the tightness adjusting mechanism 2. And when the elastic cushion 51 is pressed to a certain degree, the ejector 52 can push the first elastic part 432 to be separated from the first metal sheet 431 so as to cut off a transmission path of the first control signal, so that the tightness adjusting mechanism 2 stops working, and the size of the bracket main body 1 is kept at the current position, therefore, the embodiment realizes the purpose of automatically adjusting the size of the bracket main body 1 according to the wearing comfort level, and improves the wearing convenience.

In the process of automatically adjusting the size of the bracket main body 1 by tightening the adjusting mechanism, when the bracket main body 1 is tightened or loosened to the limit position, that is, when the two telescopic arms 11 move to the overlappable maximum size or minimum size and cannot be further adjusted, if the motor of the tightening adjusting mechanism continuously rotates, the motor is in a locked-rotor state and generates larger noise, even the motor is damaged.

The problem that the motor is locked when the bracket main body 1 is tightened or loosened to the limit position is solved in the following embodiments.

In this application, the head-mounted device support further includes a second switch, and the second switch is used for turning on or off an electrical connection path between the control module and the tightness adjusting mechanism 2; the telescopic arm 11 has a retracted limit position, and when the length of the telescopic arm 11 is in the retracted limit position, the second switch disconnects the electrical connection path between the control module 3 and the slack adjuster mechanism 2.

The second switch may have various configurations, and may be, for example, a single-pole double-throw switch. The second switch may also be a piezoelectric switch which can be pressed when the telescopic arm 11 has the contraction limit position, thereby triggering the piezoelectric switch, and the tightness adjusting mechanism 2 stops working in response to an output signal of the piezoelectric switch, so that the telescopic arm 11 is maintained at the current length.

Referring to fig. 5 and 6, fig. 5 is a diagram illustrating a usage state of the head-mounted device after the rear shell is hidden in fig. 1; fig. 6 is a cross-sectional view of the disclosed headset along the thickness direction. Specifically, in an embodiment, the housing assembly 4 is further provided with a second metal sheet 61, and the second metal sheet 61 correspondingly extends along the length direction of the telescopic arm 11; a second elastic piece 62 is arranged on one side of the telescopic arm 11 facing the second metal sheet 61; the second elastic piece 62 and the second metal sheet 61 are both connected in series between the control module 3 and the tightness adjusting mechanism 2, and the second elastic piece 62 is in contact with and electrically connected with the second metal sheet 61; the second elastic member 62 can move to the outside of the end of the second metal sheet 61 with the telescopic arm 11 to cut off the transmission path of the first control signal.

In one example, the second metal sheet 61 is disposed on the rear case 42 of the housing assembly 4. The second elastic member 62 is in the shape of a bar and is disposed on one of the two telescopic arms 11 near the rear housing 42. The second metal piece 61 may be disposed near the upper edge of the rear case 42 with reference to the orientation of the head-mounted device when it is normally worn.

One telescopic arm 11 of the two telescopic arms 11 close to the front shell 41 is referred to as a first telescopic arm 111, and one telescopic arm 11 close to the rear shell 42 is referred to as a second telescopic arm 112; the second elastic member 62 is located between the rear case 42 and the second telescopic arm 112, and the second elastic member 62 is in contact with the second metal sheet 61 under the action of its own elastic force to realize electrical connection.

When the two telescopic arms 11 are contracted, the second elastic element 62 on one telescopic arm 11 close to the rear shell 42 slides on the second metal sheet 61, so that the first control signal sent by the control module 3 can be normally transmitted to the driving plate of the slack control mechanism. When the second elastic member 62 slides to the outer side of the end of the second metal sheet 61, the second elastic member 62 is electrically disconnected from the second metal sheet 61, so that the first control signal sent by the control module 3 cannot be transmitted to the driving plate of the slack control mechanism, and the motor stops working.

Here, the position at which the second elastic member 62 is moved to the end of the second metal sheet 61 corresponds to the maximum length position at which the two telescopic arms 11 can be overlapped, that is, the contraction limit position of the stent main body 1. It may also correspond to the vicinity of the maximum length position at which the two telescopic arms 11 can overlap, i.e. the position immediately close to the limit of tightening.

It can be seen that, in this embodiment, through the setting of second sheetmetal 61 and second sheetmetal 61 for during the maximum length position that two telescopic booms 11 can overlap, second sheetmetal 61 and second sheetmetal 61 break off the electricity and connect, so that the motor can't accept first control signal, thereby make the motor automatic shutdown work, thereby eliminated the emergence of locked rotor phenomenon, in order to guarantee wear-type electronic equipment's work security and improved user experience.

Embodiments of the second elastic member 62 will be described in the following examples.

Referring to fig. 8, fig. 8 is a schematic structural view of an embodiment of a second elastic member and a second metal sheet; in an embodiment, the second elastic element 62 includes a second elastic piece 621, and the second elastic piece 621 includes a first bending portion 6211 and a second bending portion 6212 connected to each other; one side of the first bending portion 6211 departing from the second bending portion 6212 is a connection plane, and the connection plane is connected with the surface of the telescopic arm 11; the second bending portion 6212 of the second resilient tab 621 is provided for the second metal sheet 61 to contact.

In one example, the first bent portion 6211 is generally U-shaped, and the second bent portion 6212 is coupled to an arm of the first bent portion 6211 and is generally hook-shaped. The connection plane on the first bending portion 6211 can be in surface-to-surface contact with the telescopic arm 11, thereby improving the connection stability. In particular, the connection may be made by means of adhesive bonding. The second elastic member 62 in this embodiment has two bent portions, so that the second elastic member has a better elastic force to ensure a reliable contact with the second metal sheet 61.

Referring to fig. 7, fig. 7 is a circuit control block diagram of another embodiment of the head mounted device of the present disclosure. The first control signal output by the 3V + terminal of the control module may be electrically connected to the second elastic element 62, and the second metal sheet 61 may be connected to the input terminal of the driving circuit 221, or of course, the first control signal output by the 3V + terminal of the control module may be electrically connected to the second metal sheet 61, and the second elastic element 62 may be connected to the input terminal of the driving circuit 221. Therefore, when the second elastic member 62 is electrically connected to the second metal sheet 61, the driving circuit 221 can receive the first control signal, so that the motor operates normally.

It should be noted that, since the first elastic member 432, the first metal sheet 431, the second elastic member 62 and the second elastic member 62 are all used for conducting the first control signal, they can be connected in series in the same loop.

Referring to fig. 9, fig. 9 is a schematic structural view of another embodiment of the second elastic member and the second metal sheet. In another embodiment, the second elastic element 62 includes two second elastic pieces 621 arranged side by side, one second elastic piece 621 is electrically connected to the control module 3, and the other second elastic piece 621 is electrically connected to the driving circuit 221 of the slack adjuster 2; the second bending portions 6212 of the two second resilient sheets 621 are connected to the second metal sheet 61.

In this embodiment, the second metal sheet 61 functions to electrically connect the two second elastic pieces 621. Similarly, when the second elastic element 62 slides out of the end position of the second metal sheet 61, the second metal sheet 61 cannot electrically connect the two second elastic sheets 621, so that the control module 3 is electrically disconnected from the driving circuit 221 of the slack adjuster mechanism 2, and the motor stops working.

Further, the head-mounted device support further comprises a third switch, and the third switch is used for switching on or off an electric connection path between the control module and the tightness adjusting mechanism; the telescopic arm is provided with a loosening limit position, and when the length of the telescopic arm is in the loosening limit position, the third switch disconnects an electric connection path between the control module and the tightness adjusting mechanism.

The third switch may have various structures, such as a single-pole double-throw switch. The third switch may also be a piezoelectric switch which can be pressed when the telescopic arm 11 has a retracted extreme position, thereby triggering the piezoelectric switch, and the tightness adjusting mechanism 2 stops working in response to an output signal from the piezoelectric switch, so that the telescopic arm 11 is maintained at the current length.

In one example, the control module 3 sends a second control signal to the slack adjuster mechanism 2 to reduce the overlapping length of the two telescopic arms 11; a third metal sheet 63 is arranged on the shell component 4, and the third metal sheet 63 extends along the length direction of the telescopic arm 11; a third elastic piece 64 is arranged on one side of the telescopic arm 11 facing the third metal sheet 63; the third elastic member 64 and the third metal sheet 63 are connected in series between the control module 3 and the slack adjuster 2, and the third elastic member 64 is in contact with and electrically connected to the third metal sheet 63; the third elastic member 64 can move to the outside of the end of the third metal piece 63 with the telescopic arm 11 to cut off the transmission path of the second control signal.

In one example, the third metal sheet 63 is disposed on the rear case 42 of the housing assembly 4. The third elastic member 64 is in the shape of a bar and is disposed on one telescopic arm 11 of the two telescopic arms 11 near the rear housing 42. The third metal piece 63 may be provided at a position near the upper edge of the rear case 42 with reference to an orientation when the head-mounted device is normally worn.

Here, the position at which the third elastic member 64 is moved to the end of the third metal piece 63 corresponds to the minimum length position at which the two telescopic arms 11 can overlap, that is, the release limit position of the stent body 1. It may also correspond to the vicinity of the minimum length position at which the two telescopic arms 11 can overlap, i.e. the position immediately close to the limit of relaxation.

In one example, the second metal sheet 61 and the third metal sheet 63 are sequentially disposed corresponding to the extending direction of the telescopic arm 11, and an insulation gap is formed between the second metal sheet 61 and the third metal sheet 63. In another example, the first metal sheet 431 and the second metal sheet 61 are integrally provided, and the first metal sheet 431 and the second metal sheet 61 may be isolated from each other by an insulator.

When the two telescopic arms 11 move away from each other to loosen the bracket body 1, the third elastic member 64 on one telescopic arm 11 close to the rear shell 42 slides on the third metal sheet 63, so that the second control signal sent by the control module 3 can be normally transmitted to the drive plate of the tightness control mechanism. When the third elastic member 64 slides to the outer side of the end of the third metal sheet 63, the third elastic member 64 is electrically disconnected from the third metal sheet 63, so that the second control signal sent by the control module 3 cannot be transmitted to the driving plate of the slack control mechanism, and the motor stops working.

It can be seen that, in this embodiment, through the setting of third sheetmetal 63 and third sheetmetal 63 for when two telescopic boom 11 relative motion to the minimum length position that can overlap, the motor can't receive first control signal, thereby makes the motor automatic shutdown work, thereby has eliminated the emergence of locked rotor phenomenon, in order to guarantee wear-type electronic equipment's work security and to improve user experience.

An embodiment of the third elastic member 64 will be described in the following examples.

In an embodiment, the third elastic element 64 includes a third elastic piece 641, and the third elastic piece 641 include a first bending portion 6211 and a third bending portion connected to each other; one side of the first bending part 6211 away from the third bending part is a connection plane, and the connection plane is connected with the surface of the telescopic arm 11; the third bending portion of the third elastic piece 641 is used for the third metal piece 63 to contact.

In one example, the first bent portion 6211 is generally U-shaped, and the third bent portion is connected to one arm of the first bent portion 6211 and is generally hook-shaped. The connection plane on the first bending portion 6211 can be in surface-to-surface contact with the telescopic arm 11, thereby improving the connection stability. In particular, the connection may be made by means of adhesive bonding. The third elastic member 64 of the present embodiment has two bent portions, so that the third elastic member has a better elastic force to ensure a reliable contact with the third metal sheet 63.

In the figure, the second control signal output by the V-terminal of the control module 3 may be electrically connected to the third elastic element 64, the third metal plate 63 may be connected to the input terminal of the driving circuit 221, of course, the first control signal output by the V + terminal of the control circuit may be electrically connected to the third metal plate 63, and the third elastic element 64 may be connected to the input terminal of the driving circuit 221. Therefore, when the third elastic member 64 is electrically connected to the third metal sheet 63, the driving circuit 221 can receive the first control signal, so that the motor operates normally.

In another embodiment, the third elastic element 64 includes two third elastic pieces 641 arranged side by side, one third elastic piece 641 is electrically connected to the control module 3, and the other third elastic piece 641 is electrically connected to the driving circuit 221 of the slack adjuster 2; the third bending portions of the two third elastic pieces 641 are connected to the third metal piece 63.

In this embodiment, the third metal sheet 63 serves to electrically connect the two third elastic sheets 641. Similarly, when the third elastic element 64 slides out of the end position of the third metal sheet 63, the third metal sheet 63 cannot electrically connect the two third elastic sheets 641, so that the control module 3 is electrically disconnected from the driving circuit 221 of the slack adjuster mechanism 2.

To sum up, through setting up second elastic component 62 and second sheetmetal 61, third elastic component 64 and third sheetmetal 63 to according to two telescopic boom 11 tighten up size control slack adjuster 2 stop work, thereby realized wearing of automatically regulated wear-type equipment, improved the convenience of wearing.
