The housing 110 serves as a packaging housing that can integrally enclose the adjustment mechanism 120 such that only the mounting strap 130 and the adjustment strap 140 can be extended to fixedly connect with the VR host 210.

Referring to fig. 2 and 4 together, the outer case 110 may include a case body 111, a rear cover 113, and a mounting plate 115.

The housing body 111 has a cavity, and the rear cover 113 can be fastened to the opening end of the housing body 111 for fixing the adjusting mechanism 120 inside the outer housing 110. The mounting plate 115 may be fixedly attached to the inside of the rear cover 113 for attaching the locker 123 and can provide a guide for the movement of the locker 123.

Specifically, the housing body 111 may include a top surface 1112, side surfaces 1114, and a front surface 1116 corresponding to the rear cover 113.

A through hole may be opened in the front 1116 of the case body 111. When the locking member 123 is installed in the cavity of the housing 110 and connected to the mounting plate 115, the pressing portion 1230 of the locking member 123 can pass through the through hole and be exposed out of the housing 110. When the user needs to release the VR head strap adjustment structure 100, the locking member 123 and the one-way wheel 1212 can be unlocked by only pressing the locking member 123. Meanwhile, the top surface 1112 and the side surface of the housing body 111 may also be provided with corresponding through holes, so that the fixing strap 130 and the adjusting strap 140 may extend through the through holes.

In fig. 4, a through hole formed in a side surface of the housing body 111 is formed along the first direction 005, a through hole formed in a top surface 1112 of the housing body 111 is formed along the second direction 007, and a through hole formed in a front surface 1116 of the housing body 111 is formed along the third direction 009. The first direction 005 and the third direction 009 may be perpendicular, and the first direction 005 and the second direction 007 may also be perpendicular. In other words, fixing strap 130 is mounted in the cavity of housing 110 for telescopic movement in first direction 005, adjustment strap 140 is mounted in the cavity of housing 110 for telescopic movement in second direction 007, and locking member 123 is mounted for telescopic movement in third direction 009 with respect to housing 110.

It is understood that in alternative embodiments, the first direction 005 and the second direction 007 may not be perpendicular, and the first direction 005 and the third direction 009 may not be perpendicular. The present application is not limited, and is specifically determined according to actual needs.

To allow adjustment mechanism 120 to be in the unlocked state, securing strap 130 may be automatically reset to release.

Referring to fig. 2 and 5, the adjusting mechanism 120 may further include a first restoring member 127.

Optionally, a stopping portion 1110 is protruded from an inner side wall of the housing 110, and a mounting portion 137 is disposed on a side of the fixing band 130 close to the adjusting mechanism 120. The mounting portion 137 is opposite to the blocking portion 1110 and may form a mounting groove, and the first restoring member 127 may be embedded in the mounting groove.

After being installed, one end of the first restoring element 127 abuts against the installation portion 137 of the fixing band 130, and the other end abuts against the stopping portion 1110 of the housing 110. When the adjusting mechanism 120 is in the locking state, the first restoring element 127 is pressed to generate a restoring force under the pressing of the stopping portion 1110 and the mounting portion 137. When the adjusting mechanism 120 is in the unlocked state, the restoring force of the first restoring member 127 pushes the fixing strap 130 to move away from the adjusting mechanism 120, thereby loosening the fixing strap 130.

Alternatively, the first restoring member 127 may be a spring, and may specifically be a compression spring. When the spring is compressed, a restoring force is generated, and after the adjustment mechanism 120 is unlocked, the restoring force of the spring drives the fixing strap 130 to move relative to the housing 110 in a direction away from the adjustment mechanism 120.

Optionally, referring to fig. 2 and 6, the locking member 123 is adapted to cooperate with the one-way wheel 1212 of the driving shaft 121, and the locking member 123 can move telescopically in the third direction 009 within the cavity of the housing 110 to engage with or disengage from the one-way wheel 1212.

Specifically, the locker 123 may include a pressing portion 1230, and a connecting rod 1233 and a hook 1235 protrudingly provided at one side of the pressing portion 1230. The number of the connecting rods 1233 may be two, and the two connecting rods 1233 are arranged in parallel. The coupling bar 1233 is adapted to cooperate with the housing 110 to provide a guide for the movement of the locker 123 in the third direction 009. The hook 1235 is used for being clamped with the one-way wheel 1212, and the locking piece 123 can move relative to the housing 110 in the third direction 009, so that the hook 1235 can have a first state of being clamped with the one-way wheel 1212 and a second state of being released from being clamped.

In order to make the adjusting mechanism 120 in the locked state, the hook 1235 of the locking member 123 and the one-way wheel 1212 can be firmly clamped and not easily released. Optionally, the adjustment mechanism 120 may further include a second reset 129.

Specifically, the second reset member 129 can be sleeved on the connecting rod 1233, and after the locking member 123 and the housing 110 are installed, one end of the second reset member 129 abuts against the housing 110, and the other end of the second reset member 129 abuts against the pressing portion 1230, so that the clamping force is always kept between the hook 1235 and the one-way wheel 1212, and the locking member is not easily released.

The pressing portion 1230 of the locking member 123 may be protruded from the through hole of the front 1116 of the housing body 111 during installation. When the unlocking is needed, the user presses the pressing portion 1230 of the locking member 123, so that the locking member 123 can move telescopically along the third direction 009 under the action of an external force, and further the second resetting member 129 is compressed, and the hook 1235 and the one-way wheel 1212 are separated to unlock.

In order to facilitate the locking member 123 to move telescopically along the third direction 009 by an external force, the hook 1235 does not interfere with the housing.

Alternatively, with continued reference to FIG. 6, retaining member 123 may be coupled to mounting plate 115.

Specifically, the mounting plate 115 may be formed with an escape groove 1150 and a connection hole 1153. The mounting plate 115 is fixedly connected to the inner side of the rear cover 113, the connecting rod 1233 of the locking member 123 is inserted into the connecting hole 1153 of the mounting plate 115, and the second restoring member 129 is sleeved on the connecting rod 1233, such that one end of the second restoring member 129 abuts against the mounting plate 115, and the other end abuts against the pressing portion 1230. The groove 1150 of dodging that the trip 1235 just in time can wear to locate the mounting panel 115 is in contact with the one-way wheel 1212 joint, and retaining member 123 is when following third direction 009 concertina movement, dodges the groove 1150 and just in time dodges the space for trip 1235 provides, prevents to interfere among the concertina movement process.

The second belt 135 is provided with a second transmission part provided with a second rack 1350. When the first belt 132 and the second belt 135 are installed alternately, the first rack 1320 of the first belt 132 and the second rack 1350 of the second belt 135 are oppositely disposed in parallel. The external gear 1250 is drivingly connected between the first rack 1320 and the second rack 1350, and the external gear 1250 can respectively drive the first rack 1320 and the second rack 1350 to move in two opposite directions by rotating.

The first transmission portion of the first belt 132 may have a first elongated hole, and the first rack 1320 is disposed on an inner sidewall of one side of the first elongated hole. Correspondingly, a second elongated hole may be formed on the second transmission portion of the second belt 135, and the second rack 1350 is disposed on an inner sidewall of one side of the second elongated hole. After installation, the first elongated hole and the second elongated hole are basically overlapped to form an elongated hole, the first rack 1320 and the second rack 1350 are respectively positioned at two sides of the elongated hole, and the external gear 1250 is respectively in meshing transmission with the first rack 1320 and the second rack 1350.

As shown in fig. 1, the ends of the first and second bands 132 and 135 away from the adjusting mechanism 120 are further opened with a connecting hole 1153, so that the fixing strap 130 and VR can be fixedly connected by opening the connecting hole 1153.

Alternatively, the adjustment strap 140 may be wound around the drive shaft 121 and include opposite fixed and movable ends. Wherein, the stiff end of regulation band 140 is used for carrying out fixed connection with the VR host computer, and the expansion end of regulation band 140 can be around locating drive shaft 121, and can drive shaft 121 and rotate. When the user pulls the movable end of the adjustment belt 140, the adjustment belt 140 can drive the driving shaft 121 to rotate in the first rotation direction 002 by the external force.
