Detailed Description
In the following description, "front", "rear", "left" and "right" are all views, and do not necessarily represent actual orientations of the virtual reality headset of embodiments of the invention relative to the user.
Referring to fig. 1, the virtual reality head knob rotation locking mechanism of the present embodiment includes: wear backshell 1, knob 2, spring 3, swing tooth 4, drive gear 5, spacing tooth 6, torsional spring 7, latch 8, fixed station 9, right rack 10, left rack 11. Wherein, knob 2, spring 3 and swing tooth 4 constitute the knob subassembly, and spacing tooth 6, torsional spring 7, latch 8 and fixed station 9 constitute spacing subassembly, and right rack 10 and left rack 11 are used for connecting VR optical component thereby wears it to user's head. The transmission gear 5 has a ratchet portion 12 and a transmission portion 13. Wherein, swing tooth 4 is rotatably installed on knob 2, and spacing tooth 6 and latch 8 are rotatably installed on the fixed station.
Referring to fig. 2, the right rack 10 and the left rack 11 are engaged with the transmission part 13 of the transmission gear 5, and when the transmission part 13 rotates, the right rack 10 and the left rack 11 can be driven to contract toward the middle or the right rack 10 can be driven to release toward the right and the left rack 11 can be driven to release toward the left.
Referring to fig. 3, in the release position, the swing teeth 4 and the limit teeth 8 are both disengaged from the ratchet wheel portion 12 of the transmission gear 5, so that the transmission gear 5 can freely rotate without being limited, and accordingly, the transmission gear 5 does not apply torque to the right rack 10 and the left rack 11, so that the left rack 11 and the right rack 10 can freely slide in the left-right direction, so that the user can adjust the size of the virtual reality headset to be larger, and the head can extend into the virtual reality headset. The rear head-mounted shell 1 is provided with a clamping bone 14, and the clamping bone 14 limits the rotation range of the knob 2, so that the knob 2 can only rotate 180 degrees between a loosening position and a locking position. The fixed table 9 is provided with a limiting column 16, and the knob 2 is provided with a spring 3. The spring 3 provides a pulling force to the oscillating tooth 4, but in the released position, the limit post 16 blocks the oscillating tooth 4, keeping the oscillating tooth 4 disengaged from the ratchet part 12. Still install latch 8 and torsional spring 7 on the fixed station 9, latch 8 can be around the pivot rotation on the fixed station 9. The torsion spring 7 provides a driving force for the stopping tooth 6 to make the stopping tooth 6 tend to engage with the ratchet part 12, but in the release position, the latch 8 is pressed against one end of the stopping tooth 6 to make the stopping tooth 6 keep disengaging from the ratchet part 12. The fixed table 9 is provided with a stop pillar 15, and in a release position, the stop pillar 15 abuts against one end of the latch 8, so that the other end of the latch 8 abuts against one end of the limit tooth 6, and the limit tooth 6 is disengaged from the ratchet part 12.
Referring to fig. 4, during the rotation of the knob 2 from the release position to the lock position, the limit teeth 6 and the swing teeth 4 are engaged with the ratchet portion 12 of the transmission gear 5. With the rotation of the knob 2, the swing tooth 4 drives the transmission gear 5 to rotate, so that the left rack 11 and the right rack 10 are tightened, and the limit tooth 6 limits the reverse rotation of the transmission gear 5 towards the loosening position. Like this, just realize two functions of the wearing elasticity of virtual reality and locking through knob 2, only have a drive gear 5, simple structure, with low costs, small, convenient operation.
As can be seen from fig. 4, during the rotation of the knob 2 from the release position to the lock position, the swing tooth 4 changes relative to the position of the position-limiting post 16 as the knob 2 moves, the position-limiting post 16 releases the blocking of the swing tooth 4, the spring 3 pulls the swing tooth 4, the swing tooth 4 swings into a state of being engaged with the ratchet portion 12, and thus when the knob 2 is further rotated, the swing tooth 4 transmits the torque of the knob 2 to the transmission gear 5. In the process of rotating from the loosening position to the locking position, the latch 8 is separated from the limiting tooth 6, and the torsion spring 7 drives the limiting tooth 6 to rotate, so that the limiting tooth 6 enters a state of being meshed with the ratchet wheel part 12.
Referring to fig. 5, when the knob assembly is rotated by the knob 2, the spring 3 and the swing teeth 4 of the knob 2 do not interfere with the fixed stage 9, and the knob 2 is rotatable.
Referring to fig. 6, 7 and 8, the knob 2 is provided with three end surfaces, a first end surface 17, a second end surface 18 and a third end surface 19. As can be seen from fig. 6 and 7, in the release position, the first end face 17 does not push the latch 8; the second end surface 18 assists in limiting the rotation of the limiting teeth 6, so that the limiting teeth 6 are kept in a disengaged state with the ratchet wheel part 12; the third end surface 19 assists in keeping the latch 8 against the stop tooth 6. As can be seen from fig. 8, in the process that the knob 2 rotates from the release position to the locking position, the first end surface 17 drives the latch 8 to rotate to disengage from the catch 15, and the latch 8 disengages from the limit tooth 6; the second end surface 18 generates displacement along with the rotation of the knob 2, and the limitation on the limiting teeth 6 is removed; the third end surface 19 is disengaged from the latch 8.
When the locking position shown in fig. 8 is rotated to the releasing position shown in fig. 7, the second end surface 18 drives the limiting tooth 6 to overcome the elastic force of the torsion spring 7 and disengage from the ratchet part 12, and then the third end surface 19 drives the latch 8 to rotate until the latch 8 abuts against the stop post 15, so that the latch 8 abuts against one end of the limiting tooth 6. This means that the virtual reality headset can be brought back into the state of adjustable tightness by only rotating one knob 2.
As shown in fig. 7 and 8, the knob 2 further includes a stopper 20, and after the stopper post 16 on the fixing base 9 releases the blocking of the rocking teeth 4, the stopper 20 restricts further rocking of the rocking teeth 4 so that the rocking teeth 4 are not disengaged from the ratchet portion 12.
The above description is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention, and all equivalent substitutions and modifications made to the above embodiment should fall within the protection scope of the present invention.
