Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

In order to implement single-screen IPD adjustment in electronic equipment, this embodiment designs an adjustment structure for IPD adjustment, and in particular relates to an electronic equipment 100.

Referring to fig. 1 to 4, the electronic device 100 mainly includes a housing 10, a display 20, a display bracket 30, a left barrel 40, and a right barrel 40'.

Referring to fig. 1 and 7, the case 10 forms an external appearance surface of the electronic apparatus 100, and a receiving space C in which all electric devices in the electronic apparatus 100 are received is formed in the case 10.

The display screen bracket 30 is disposed in the housing 10, and is used for carrying the display screen 20, the left lens barrel 40 and the right lens barrel 40'.

The front side of the display screen bracket 30 is provided with a whole piece of display screen 20 corresponding to the left lens barrel 40 and the right lens barrel 40', which can be adhered to the display screen bracket 30 by an adhesive such as PSA (pressure sensitive adhesive), so that the pictures displayed in the left lens barrel 40 and the right lens barrel 40' are displayed in the display screen 20. The use of one display 20 reduces product cost and improves picture consistency over dual displays.

The left and right sides of the rear side of the display screen support 30 are respectively provided with a left lens barrel 40 and a right lens barrel 40', and the left lens barrel 40 and the right lens barrel 40' can be linked and can move relatively (i.e. reduce the IPD) or move backwards (i.e. increase the IPD) along the display screen support 30 at the same time when moving.

The user can rotate any one of the left lens barrel 40 and the right lens barrel 40 'with one hand, and can simultaneously drive the left lens barrel 40 and the right lens barrel 40' to simultaneously move relatively or move backwards.

Generally, when a user wears the head-mounted device and needs to adjust the IPD, the user operates the left lens barrel 40 with the left hand and simultaneously operates the right lens barrel 40 'with the right hand to rotate the left lens barrel 40 and the right lens barrel 40' in opposite directions, thereby achieving a relative movement therebetween (i.e., reducing the IPD) or a simultaneous backward movement (i.e., increasing the IPD). The opposite rotation refers to that the right barrel 40 'rotates counterclockwise when the left barrel 40 rotates clockwise, and the right barrel 40' rotates clockwise when the left barrel 40 rotates counterclockwise.

The left barrel 40 and the right barrel 40' can also independently perform the adjustment movement.

After the IPD is adjusted, only after the positions of the left lens barrel 40 and the right lens barrel 40' are known, the picture displayed in the display screen 20 can be controlled and adjusted to achieve the best display effect.

To this end, the electronic apparatus 100 is further provided with a controller (not shown) and a displacement detecting assembly connected to the controller for detecting the positions of the left and right barrels 40 and 40' after the relative or reverse movement and feeding back to the controller, which in turn adjusts the position of the picture displayed in the display screen 20.

If the left barrel 40 and the right barrel 40 'are linked, in order to detect the relative movement displacement between the two, in the present application, referring to fig. 2, 3 and 6, a hall sensor 50 is fixedly disposed on the inner side wall of the display screen bracket 30, and correspondingly, a magnet 60 corresponding to the hall sensor 50 is disposed on the left barrel 40 or the right barrel 40'.

When the IPD is not adjusted, the magnet 60 on the left barrel 40 or the right barrel 40' has a certain original distance from the hall sensor 50, and the hall sensor 50 senses the magnetic field of the magnet at the original distance. When the IPD is adjusted, the linkage of the left barrel 40 and the right barrel 40' drives the magnet 60 to move left or right, and at this time, the distance between the hall sensor 50 and the magnet 60 is changed, so that the hall sensor 50 senses the change of the magnetic field strength when the distance between the hall sensor 50 and the magnet 60 is changed, the hall sensor 50 feeds back a detection signal indicating the change of the magnet strength (i.e., the barrel movement distance) to a controller (not shown), and the controller adjusts the picture displayed on the display screen 20 to realize the IPD adjustment.

In an alternative embodiment, the magnet 60 may be fixed on the inner sidewall of the display screen bracket 30, and the hall sensor 50 is disposed on the left barrel 40 or the right barrel 40 'corresponding to the magnet 60, so that it is required to ensure that the wire connecting the hall sensor 50 and the controller is not wound or pulled when the hall sensor 50 moves along with the movement of the left barrel 40 or the right barrel 40'.

In an alternative embodiment, a transmission sensor of the transmission wave type, such as a millimeter wave or ultrasonic radar, may be used to detect the relative displacement change of the left barrel 40 and the right barrel 40'.

When the IPD is not adjusted by the left barrel 40 or the right barrel 40', the transmission sensor transmits an optical wave to the left barrel 40 or the right barrel 40', which is recorded with a certain original distance from the left barrel 40 or the right barrel 40 '. When the IPD is adjusted, the linkage of the left barrel 40 and the right barrel 40' changes the difference between the return time and the transmission time of the transmission from the transmission sensor to the left barrel 40 or the right barrel 40', so the transmission sensor can know the displacement change of the transmission from the left barrel 40 or the right barrel 40', and feed back the detection signal indicating the displacement change (i.e., the barrel movement distance) to the controller (not shown), and the controller adjusts the picture displayed on the display screen 20 to realize the IPD adjustment.

In an alternative embodiment, the left barrel 40 or the right barrel 40' may be adjusted in multiple stages, and after each stage is adjusted in place (e.g., moved in place relatively or away from each other), the sensor at the corresponding position detects the displacement of each stage after adjustment, and the controller adjusts the image displayed on the display screen 20 accordingly.

When the left barrel 40 and the right barrel 40 'are independently adjusted, the displacement detecting assembly may include a displacement detecting portion for the left barrel 40 and a displacement detecting portion for the right barrel 40'.

The controller can control and adjust the picture displayed on the display screen 20 as long as the two displacement detection parts can respectively detect the displacement of the left lens barrel 40 and the right lens barrel 40 after the relative or back movement of the left lens barrel 40 and the right lens barrel 40' can be known.

The above-described manners are displacement detection performed by the user with manual adjustment of one or both of the left and right barrels 40, 40'.

Of course, a means for automatically detecting the movement displacement of the left barrel 40 or the right barrel 40' and automatically adjusting the picture in the display screen 20 may be adopted.

For example, an interpupillary distance detecting sensor (not shown) is disposed in the electronic device 100, and when the user wears the electronic device 100, the interpupillary distance detecting sensor can automatically detect the interpupillary distance of the user, feed the interpupillary distance back to the controller, and control the driving assembly to drive one or both of the left lens barrel 40 and the right lens barrel 40' to automatically move relatively or reversely.

The driving assembly as described above may include a motor and a transmission assembly (e.g., a chain wheel and chain assembly, etc.) in driving connection with the motor, and the transmission assembly transmits the driving force of the motor controlled by the controller to one or both of the left barrel 40 and the right barrel 40' to realize the automatic relative or backward movement of the two.

In order to realize that the left lens barrel 40 and the right lens barrel 40 'can move relatively or move back and forth along the display screen bracket 30, the electronic device is further provided with a guiding device which is fixedly arranged on the display screen bracket 30, and the left lens barrel 40 and the right lens barrel 40' are arranged on the guiding device in a sliding way.

Specifically, as shown in fig. 1 to 4, the guide device includes a long guide shaft c1, a first short guide shaft d1, and a second short guide shaft d2 fixed to the display screen bracket 30, respectively.

Correspondingly, the upper end of the left barrel 40 is provided with the guide lugs 41 arranged side by side, the upper end of the right barrel 40 'is provided with the guide lugs 41' arranged side by side, the guide lugs 41 and 41 'are respectively provided with a through groove, the long guide shaft c1 respectively passes through the through grooves of the guide lugs 41 and the through grooves of the guide lugs 41', the notch areas of the through grooves of the guide lugs 41 and the through grooves of the guide lugs 41 'are larger than the cross-sectional area of the long guide shaft c1, and therefore the left barrel 40 and the right barrel 40' can be ensured to slide along the long guide shaft c1 in a guiding way. In order to fix the long guide shaft c1 on the display screen bracket 30 and limit the sliding range of the left barrel 40/right barrel 40' along the long guide shaft c1 (to prevent the sliding range of the left barrel 40/right barrel 40' from exceeding the range of the display screen 20), referring to fig. 5, a rack block 72' fixedly connected with the display screen bracket 30 is provided, and the rack block 72' includes a connecting block 721' and a hanging lug 722' connected with the connecting block 721 '. The hanging lug 722' is provided with a through hole through which the long guide shaft c1 passes.

And the size of the hanging lug 722 'is larger than that of the guide lugs 41 and 41' and is respectively provided with a through groove.

In the present application, the fixing of the long guide shaft c1 to the display screen bracket 30 may be achieved by dispensing at a gap between the through hole of the hanging lug 722' and the long guide shaft c 1.

Also in the present application, the rack block may be provided on each of the left and right barrels 40 and 40 '(adapted to the left and right barrels 40 and 40' to move in conjunction or independently), or may be provided on one of the left and right barrels 40 and 40 '(adapted to the left and right barrels 40 and 40' to move in conjunction).

Two guiding lugs 41 arranged at the upper end of the left barrel 40 are respectively arranged at two sides of a rack block 72' on the left barrel 40 for forming a first limiting piece and a second limiting piece, and the first limiting piece and the second limiting piece both limit the range of the left barrel 40 sliding along the left-right direction.

Two guiding lugs 41 'provided at the upper end of the right barrel 40' are respectively provided at both sides of the rack block on the right barrel 40 'for forming a third limiting member and a fourth limiting member, both of which limit the range of the right barrel 40' sliding in the left-right direction.

The first short guide shaft d1 is fixedly provided on a portion of the display screen bracket 30 located at the lower end of the left barrel 40, and the second short guide shaft d2 is fixedly provided on a portion of the display screen bracket 30 located at the lower end of the right barrel 40.

A clip k1 is fixedly arranged on the first short guide shaft d1, a clip k2 is fixedly arranged on the second short guide shaft d2, the clip k1 is in sliding contact with the left lens barrel 40, and the clip k2 is in sliding contact with the right lens barrel 40', so that the left lens barrel 40 and the right lens barrel 40' are ensured to respectively slide along the first short guide shaft d1 and the second short guide shaft d2 in a guiding manner.

Alternatively, a side-by-side guide lug may be provided at the lower end of the left barrel 40, and a side-by-side guide lug may also be provided at the lower end of the right barrel 40', the guide lugs being respectively opened with a through groove, the first short guide shaft d1 passing through the through groove of the guide lug of the left barrel 40, and the second short guide shaft d2 passing through the through groove of the guide lug of the right barrel 40', wherein the notch area of the through groove of the guide lug of the left barrel 40 is larger than the cross-sectional area of the first short guide shaft d1, and the notch area of the through groove of the guide lug of the right barrel 40 'is larger than the cross-sectional area of the second short guide shaft d2, so that the left barrel 40 and the right barrel 40' are respectively guided to slide along the first short guide shaft d1 and the second short guide shaft d 2.

Of course, the long guide shaft c1 may be fixedly provided with a first clip and a second clip, the first clip being in sliding contact with the left barrel 40, and the second clip being in sliding contact with the right barrel 40', so as to ensure that the left barrel 40 and the right barrel 40' are guided and slid along the long guide shaft c 1.

In order to achieve the linkage between the left and right barrels 40 and 40', in the present application, a rack and pinion assembly is provided.

Specifically, referring to fig. 1, 2 and 6, a protrusion is formed on a portion of the left barrel 40 adjacent to the right barrel 40', a first rack 42 is formed on an upper side surface of the protrusion, and an extension length of the first rack 42 is along a left-right direction. A projection is also formed at a portion of the right barrel 40' adjacent to the left barrel 40, a second rack 42' is formed on a lower side of the projection, an extending length of the second rack 42' is in the left-right direction, and the second rack 42 and the first rack 42 are parallel and opposite.

For example, when the user rotates the left barrel 40 counterclockwise and rotates the right barrel 40 'clockwise, the gear I rotates clockwise, the left barrel 40 and the right barrel 40' move relatively close to each other, and the IPD decreases. When the user rotates the left barrel 40 clockwise and rotates the right barrel 40 'counterclockwise, the gear I rotates counterclockwise, the left barrel 40 and the right barrel 40' move away from each other, and the IPD increases.

Referring to fig. 6, in order to properly arrange the magnet 60, a protrusion provided on the right barrel 40' is concavely provided with a receiving groove (not labeled) on a side facing the hall sensor 50, and the magnet 60 is interference-inserted into the receiving groove.

Referring to fig. 3, in the present embodiment, a first bubble cotton ring p1 is provided between the left barrel 40 and a portion of the left barrel 40 in contact with the display screen bracket 30, and a second bubble cotton ring p2 is provided between the right barrel 40 'and a portion of the right barrel 40' in contact with the display screen bracket 30.

The first foam ring p1 and the second foam ring p2 mainly have two functions: 1. dust prevention function: in the process of adjusting the IPD by a user, dust is prevented from entering the inner cavity through a gap between the lens barrel and the display screen support 30; 2. stopping action: in the process of adjusting the IPD by a user, the friction force generated by compressing the foam meets the locking function of the lens barrel in real time, and the lens barrel is prevented from shaking.

If the electronic equipment can adjust the exit pupil distance on the basis of IPD adjusting power, the performance and the competitiveness of the product are greatly improved. Therefore, in the present application, the electronic device further comprises an exit pupil distance adjusting means for adjusting the exit pupil distance.

The exit pupil distance is the distance from the last vertex of the optical system to the intersection point of the exit pupil plane and the optical axis, and in electronic equipment such as a telescope, a microscope, head-mounted equipment and the like, the pupil of a human eye must coincide with the exit pupil to see the whole field of view. For VR devices, different face structures also have different exit pupil distance requirements for wearing VR devices.

Referring to fig. 2, 3 and 5, the exit pupil distance adjustment device includes a rotation shaft 80 and a transmission assembly.

The rotation shaft 80 receives an external rotation force, and the user manually rotates the rotation shaft 80 and transmits the rotation shaft 80, the rotation shaft 80 having a length direction extending in the left and right direction of the electronic apparatus.

The transmission assembly receives the rotational power transmitted from the rotational shaft 80 and converts the rotational power into power for moving the display screen bracket 30 (together with the left and right barrels 40 and 40') back and forth.

The rotating shaft 80 is rotatably disposed on the housing 10, and referring to fig. 1 and 7, the rotating shaft 80 is disposed on the housing 10 by two L-shaped fixing members 11 and 11' fixed on the housing 10.

Specifically, the rotating shaft 80 is disposed on the housing 10 through a through hole formed in a side surface of the housing 10, a through hole formed in a first side surface of the L-shaped fixing member 11, and a through hole formed in a first side surface of the L-shaped fixing member 11', and the through holes formed in the side surface of the housing 10, the first side surface of the L-shaped fixing member 11, and the first side surface of the L-shaped fixing member 11' have areas larger than a cross-sectional area of the rotating shaft 80, respectively, so that the housing 10 and the L-shaped fixing members 11 and 11' do not affect rotation of the rotating shaft 80.

The rotation plane P1 of the rotation shaft 80 is perpendicular to the plane P2 in which the screen support 30 moves back and forth.

Referring to fig. 2, a transmission assembly is designed for each of the left barrel 40 and the right barrel 40', and the structures thereof are completely the same.

The structure of a transmission assembly is taken as an example for explanation.

In this application, the transmission assembly includes a first transmission assembly 70 and a second transmission assembly 70', wherein the first transmission assembly 70 is used for transmitting the rotation power of the rotation shaft 80, and the second transmission assembly 70' is used for receiving the transmitted rotation power and driving the display screen bracket 30 (together with the left and right lens barrels 40 and 40 ') to move back and forth.

Referring to fig. 5, the first transmission assembly 70 includes a first bevel gear 71 and a second bevel gear 72 engaged with the first bevel gear 71, the first bevel gear 71 is interference-fitted on the rotation shaft 80 to rotate the first bevel gear 71 together when the rotation shaft 80 is rotated by a user, and the first bevel gear 71 further transmits the rotational power to the second bevel gear 71 such that a rotational plane P3 of the second bevel gear 72 is perpendicular to a rotational plane P1 of the rotation shaft 80 and a plane P2 in which the display screen bracket 30 moves back and forth, respectively.

Of course, such power transmission is achieved not only by the first bevel gear 71 and the second bevel gear 72, but also by a power system provided in a bevel gear, a worm gear, or the like, which is not enumerated here.

The second transmission assembly 70' includes a screw 71' and a rack block 72 '.

An external thread is formed on part of the outer side wall of the screw rod 71', and a smooth outer end of the outer side wall of the screw rod 71', which is not provided with the external thread, is inserted into the central through hole of the second bevel gear 72 in an interference manner, so that the screw rod 71' can be driven to rotate when the second bevel gear 72 rotates.

The rack block 72 'is fixed to the display bracket 30, and the rack block 72' has a rack 7211 'engaged with the external thread of the screw 71', the length extension direction of the rack 7211 'coincides with the forward and backward movement direction of the display bracket 30, i.e., the screw 71' and the rack 7211 'form a worm gear structure, converting the force of the screw 71' on the rotation plane thereof into the force of the rack 7211 'on the plane in which the display bracket 30 moves forward and backward, so that the rack block 72' moves forward and backward together with the display bracket 30.

In order to fix the screw rod 71 'and the second bevel gear 72, the screw rod 71' passes through a through hole formed in the other side surface of the L-shaped fixing member 11', so that the screw rod 71' is arranged on the housing 10, wherein the hole area of the through hole is larger than the cross-sectional area of the screw rod 71', so as to ensure that the screw rod 71' can be driven to rotate when the rotating shaft 80 rotates.

Referring to fig. 5, in the present application, the rack block 72 'includes a connection block 721' and a hanging lug 722 'connected to the connection block 721'. The hanging lug 722' is provided with a through hole through which the long guide shaft c1 passes.

The upper side of the connection block 721 'is formed with the rack 7221' as described above.

Thus, when the user needs to adjust the exit pupil distance, the user holds the rotating shaft 80 to manually rotate, the first bevel gear 71 and the second bevel gear 72 convert the rotating power of the rotating shaft 80 on the rotating plane P1 into the rotating power on the rotating plane P3, and further convert the rotating power from the plane P3 into the front-back linear power on the plane P2 through the screw 71 'and the rack 7221', so that the front-back movement of the display screen bracket 30 on the plane P2 is realized, and the exit pupil distance is adjusted.

To facilitate user adjustment, referring to fig. 1-4, the electronic device 100 further includes a knob 90, wherein the knob 90 includes a cap (not labeled) having a T-shape and a lever (not labeled) connected to a bottom surface of the cap, and the lever is hollow.

One end of the rotation shaft 80 is interference-inserted into the rotation shaft of the knob 90.

In the present application, the rotating shaft 80 is located in the accommodating space C of the housing 10, and a portion of the rotating rod of the knob 90 extends into the accommodating space C of the housing 10 through a hole formed on the outer side wall of the housing 10, i.e., the cap of the knob 90 is retained outside the housing 10 for being held by the hand of the user.
