The screen module 140 is sleeved on the eyepiece module 110, and the screen module 140 can move relative to the eyepiece module 110 to change the distance between the screen module 140 and the eyepiece module 110, so as to adjust the diopter of the display device (not shown). Specifically, the screen module 140 may be close to the eyepiece module 110 or far from the eyepiece module 110, so that the diopter can be changed. In the present embodiment, the diopter corresponding to the screen module 140 located at different positions relative to the eyepiece module 110 is known, for example, the diopter of the screen module 140 moving at different positions (i.e., the distance between the screen module 140 and the eyepiece module 110 is different) has been determined through experiments.
Referring to fig. 1, 2 and 5, the driving gear 120 is mounted on the eyepiece module 110. In this embodiment, the driving gear 120 is installed above the eyepiece module 110, and in other embodiments, the driving gear 120 may also be installed at other positions of the eyepiece module, such as the left side or the right side.
In order to limit the position of the driving gear 120 and facilitate the user to manually adjust the driving gear 120, in this embodiment, the diopter adjustment display device further includes an adjustment knob 111, an upper mounting seat 112 and a lower mounting seat 113. The lower mounting base 113 is fixedly mounted on the eyepiece module 110, and the driving gear 120 is clamped between the upper mounting base 112 and the lower mounting base 113. Specifically, the driving gear 120 includes a gear body 121 and an installation shaft 123, the gear body 121 is provided with a tooth, the upper installation seat 112 is provided with a through hole, the gear body 121 is located between the lower installation seat 113 and the upper installation seat 112, and the installation shaft 123 penetrates through the through hole of the upper installation seat 112 and is assembled with the adjusting knob 111. Specifically, the adjusting knob 111 is provided with a mounting hole (not shown), and the mounting shaft 123 is mounted in the mounting hole to fix the adjusting knob 111 and the driving gear 120 together, that is, when the user rotates the adjusting knob 111 by hand, the driving gear 120 rotates synchronously.
Referring to fig. 1, 2 and 6, the driven gear 130 is rotatably sleeved on the eyepiece module 110, and the driven gear 130 is engaged with the driving gear 120. The driving gear 120 is forced to rotate to drive the driven gear 130 to rotate, and the rotation of the driven gear 130 changes the relative distance between the screen module and the eyepiece module to adjust the diopter of the display device. In this embodiment, the rotation plane of the driven gear 130 is perpendicular to the moving path of the screen module 140. In this embodiment, the driven gear 130 has a large through hole 131 in the center, the driven gear 130 is sleeved on one end of the eyepiece module 110 and one end of the screen module 140, and a notch is formed on one side of the driven gear 130 close to the eyepiece module 110, and a tooth is formed at the notch. The teeth of the driving gear 120 are engaged with the teeth of the driven gear 130, so that the driving gear 120 rotates to rotate the driven gear 130.
In this embodiment, the rotation plane of the driven gear 130 and the rotation plane of the driving gear 120 are perpendicular to each other. In this embodiment, the rotation plane of the driving gear 120 is a horizontal plane, and the rotation plane of the driven gear 130 is a vertical plane, so that the rotation planes of the two gears are perpendicular to each other, thereby saving space. In this embodiment, the driving gear 120 and the driven gear 130 are both bevel gears, so that the rotation plane of the driving gear 120 is perpendicular to the rotation plane of the driven gear 130.
Referring to fig. 2, 3, 5 and 6, the potentiometer 150 includes a resistor body 151 and at least one movable contact 152. In the present embodiment, the resistor 151 is located on the driven gear 130. Specifically, the resistor 151 is arranged on the driven gear 130 in a circumferential direction. In this embodiment, the number of the movable contact 152 is one, and the movable contact 152 is located on the driving gear 120. When the driving gear 120 drives the driven gear 130 to rotate, different positions of the elongated moving contact 152 contact different positions of the resistive element 151, so that the potentiometer 150 outputs different potential signals. In other embodiments, the potentiometer 150 includes a plurality of movable contacts 152. The plurality is greater than or equal to 2. Specifically, the plurality of moving contacts 152 are sequentially arranged on the driving gear 120 along the circumferential direction, for example, the moving contacts 152 include 6 moving contacts 152, the 6 moving contacts 152 are divided into six positions along the circumferential direction, the six positions are respectively a first position, a second position, a third position, a fourth position, a fifth position and a sixth position, and the moving contacts 152 located at the first position to the sixth position are respectively contacted with the resistor 151 during the rotation of the driving gear 120. When the driving gear 120 drives the driven gear 130 to rotate, the movable contacts 152 at different positions contact with the resistor 151, so that the potentiometer 150 outputs different potential signals. In this embodiment, the potential signal is a voltage value. In other embodiments, the potential signal may also be a resistance value, a current value, or the like. In this embodiment, the resistor 151 is electrically connected to a power supply unit, for example, both ends of the resistor 151 are electrically connected to the positive and negative electrodes of a dc power supply, or one end of the resistor 151 is electrically connected to the dc power supply and the other end is electrically grounded, so that the potentiometer 150 outputs different voltage values according to the contact position between the movable contact 152 and the resistor 151. Of course, in other embodiments, the moving contact may be located on the driven gear, and the resistive body may be located on the driving gear.
The storage unit 170 stores the correlation between the electric potential signal and diopter, and in this embodiment, the following several correlations between the electric potential signal and diopter are described below.
1. The storage unit 170 stores a potential signal-diopter table, in which the correlation between different potential signals output by the potentiometer 150 and different diopters is recorded, where the potential signals and the diopters are in a one-to-one correlation, in this embodiment, the potential signals are voltage values, and the potential signal-diopter table is described by taking the voltage value-diopter table as an example, see table 1.
TABLE 1
| Value of voltage | Diopter |
| 1V | -5D |
| 2V | -3D |
| 3V | -1D |
| 4V | 2D |
| 4.5V | 4D |
| 5V | 6D |
Different voltage values and corresponding diopters can be associated according to table 1, so that after the voltage value output by the potentiometer 150 is determined, that is, after the potential signal is determined, the corresponding diopter can be obtained.
2. The storage unit 170 stores a relational expression for calculating a correlation between different electric potential signals and different diopters, and the relational expression may be a linear relational expression or a curved relational expression.
In this embodiment, the potential signal is a voltage value, and the relationship is as follows:
Dn＝(Vn-V0)/K+D0；
wherein K, V0 and D0 are constants, Vn is the voltage value output by the potentiometer 150, and Dn is the diopter corresponding to the voltage value output by the potentiometer 150, i.e. the diopter of the current position of the screen module 140.
3. The storage unit 170 stores a potential signal range-diopter table, which records the association relationship between different potential signal ranges output by the potentiometer 150 and different diopters, that is, one potential signal range corresponds to one diopter. Here, the potential signal is a voltage value, and the voltage value range-diopter table is shown in table 2.
TABLE 2
| Range of voltage values | Diopter |
| 5V-4V (4V is excluded) | -5D |
| 4V-3.2V (3.2V excluded) | -3D |
| 3.2V-2.5V (2.5V excluded) | -1D |
| 2.5V-2.0V (2.0V excluded) | 2D |
| 2.0V-1.2V (excluding 1.2V) | 4D |
| 1.2V-0V (without 0V) | 6D |
Since the moving contact 152 contacts with different positions of the resistor 151, the potentiometer 150 outputs different potential signals, and the corresponding diopter is obtained according to the potential signals falling into the potential signal range in table 2.
Of course, in other embodiments, the storage unit may also store other information of the electric potential signal associated with the diopter, as long as the electric potential signal can be associated with the diopter.
The processing unit 160 is electrically connected to the potentiometer 150, the storage unit 170 and the screen module 140, respectively, and the processing unit 160 can obtain the potential signal output by the potentiometer 150, determine the diopter corresponding to the potential signal according to the potential signal output by the potentiometer 150 and the association relationship stored in the storage unit 170, and display the diopter on the screen module. The following description is made based on different correlations between the potential signal and the diopter stored in the storage unit 170.
1. When the storage unit 170 stores the electric potential signal-diopter table, since the processing unit 160 is electrically connected to the potentiometer 150, when the movable contact 152 contacts with different positions of the resistor 151, the potentiometer 150 outputs different electric potential signals at this time, the processing unit 160 can obtain the electric potential signals, the processing unit 160 searches the electric potential signal-diopter table according to the electric potential signals, so that the processing unit 160 obtains the diopter corresponding to the electric potential signals, and the processing unit 160 controls the screen module 140 to display the diopter. Referring to table 1, when the processing unit obtains a voltage value of 3V, the processing unit 160 searches the table 1 according to the potential signal to obtain diopter-1D corresponding to the voltage value of 3V, and the processing unit 160 controls the screen module 140 to display diopter-1D.
2. When the storage unit 170 stores the relational expression, since the processing unit 160 is electrically connected to the potentiometer 150, when the movable contact 152 is in contact with different positions of the resistor 151, the potentiometer 150 outputs different potential signals at this time, the processing unit 160 can obtain the potential signals, the processing unit 160 calculates diopter corresponding to the potential signals according to the potential signals and the relational expression, and then the processing unit 160 controls the screen module 140 to display the diopter. In the following description, taking the potential signal as a voltage value and the above-mentioned relational expression as an example, assuming that the voltage value output by the potentiometer 150 is V3, the processing unit 160 obtains the diopter corresponding to the potential signal by calculating according to the voltage value V3 and the relational expression, specifically, the voltage value V3 is substituted into the relational expression, and the processing unit 160 can obtain the diopter D3 corresponding to the voltage value by calculating as follows:
D3＝(V3-V0)/K+D0；
since V0 and K, D0 are constants and the current voltage V3 is obtained, the processing unit 160 can obtain diopter D3 corresponding to the voltage value, and thereafter, the processing unit 160 controls the screen module 140 to display diopter D3.
3. When the storage unit 170 stores the electric potential signal range-diopter table, since the processing unit 160 is electrically connected to the potentiometer 150, when the movable contact is in contact with different positions of the resistor, the potentiometer 150 outputs different electric potential signals at this time, the processing unit 160 can obtain the electric potential signals, and the processing unit 160 searches the electric potential signal range-diopter table according to the electric potential signals, so that the processing unit 160 can obtain the diopter corresponding to the electric potential signals, specifically, the processing unit 160 determines which electric potential signal range the electric potential signals fall into first, and then determines the corresponding diopter according to the electric potential signal range. The processing unit 160 controls the screen module 140 to display the diopter. Taking the potential signal as a voltage value and taking table 2 as an example, assuming that the voltage value output by the potentiometer 150 is 2.7V, the processing unit 160 can obtain the voltage value of 2.7V, and then the processing unit 160 searches table 2, it can be known that the voltage value of 2.7V falls within a voltage value range of 3.2V-2.5V (excluding 2.5V), and determines the corresponding diopter to be-1D according to the voltage value range, so as to obtain the corresponding diopter-1D, and thereafter, the processing unit 160 controls the screen module 140 to display the diopter-1D.
In this embodiment, since the driving gear 120 is forced to rotate the driven gear 130, the rotation of the driven gear 130 changes the relative distance between the screen module 140 and the eyepiece module 110 to adjust diopter, one of the resistor 151 and the movable contact 152 is located on the driven gear 130, the other is located on the driving gear 120, when the driving gear 120 drives the driven gear 130 to rotate, the movable contact 152 contacts with different positions of the resistor 151, the potentiometer 150 outputs different potential signals, the storage unit 170 stores the correlation between the potential signals and diopters, the processing unit 160 is electrically connected to the potentiometer 150, the memory unit 170 and the screen module 140 respectively, the processing unit 160 determines the diopter corresponding to the electric potential signal according to the electric potential signal output by the potentiometer 150 and the association relationship stored in the storage unit, and displays the diopter on the screen module 140. Therefore, when the user adjusts diopter, diopter can be displayed on the screen module 140, and the user experience is improved.
Referring to fig. 2 and 4, the screen module 140 includes a display screen 143 and a bracket 144, and the display screen 143 is mounted on the bracket 144 and electrically connected to the processing unit 160. The holder 144 has a cylindrical shape, and the holder 144 is connected to the driven gear 130 and the eyepiece module 110, respectively. Specifically, the bracket 144 is sleeved on the eyepiece module 110, the driven gear 130 is sleeved on the bracket 144, and when the driven gear 130 rotates relative to the eyepiece module 110, the rotation of the driven gear 130 drives the bracket 144 to move relative to the eyepiece module 110, so that the screen module 140 moves relative to the eyepiece module 110, that is, the relative distance between the screen module 140 and the eyepiece module 110 changes.
In this embodiment, in order to realize that the screen module 140 moves relative to the eyepiece module 110, even if the relative distance between the screen module 140 and the eyepiece module 110 changes, in this embodiment, please refer to fig. 1, fig. 2, fig. 4 and fig. 6, a sliding slot 114 is disposed on a side of the eyepiece module 110 close to the driven gear 130, and the sliding slot 114 is parallel to the central axis of the driven gear 130, that is, parallel to the moving path of the screen module 140. In this embodiment, the number of the sliding grooves 114 is two or other numbers, and the sliding grooves 114 are located on the outer surface of the eyepiece module 110. In this embodiment, the screen module 140 is sleeved on the eyepiece module 110, and the screen module 140 is provided with a sliding block 141 corresponding to the sliding groove 114. In this embodiment, the number of the sliding blocks 141 is also two or other numbers, the sliding blocks 141 are located on the inner side wall of the screen module 140, and the two sliding blocks 141 are correspondingly located in the two sliding slots 114; the screen module 140 is further provided with two or other detachable guide posts 142, and the screen module 140 is linked with the driven gear 130 through the guide posts. In this embodiment, the sliding block 141 and the guide post 142 are both on the bracket 144 of the screen module 140. The driven gear 130 is provided with arc-shaped holes 132, the arc-shaped holes 132 extend from a side close to the eyepiece module 110 to a side far from the eyepiece module 110, in this embodiment, the number of the arc-shaped holes 132 is two or other numbers, and the two guide posts 142 of the screen module 140 penetrate into the two arc-shaped holes 132 respectively. Therefore, when the driving gear 120 is forced to rotate, the driving gear 120 drives the driven gear 130 to rotate, and the driven gear 130 applies an acting force to the guide post 142 through the arc-shaped hole 132, so that the screen module 140 moves along the sliding groove 114, the screen module 140 moves relative to the eyepiece module 110, and the relative distance between the screen module 140 and the eyepiece module 110 is further changed. In addition, in other embodiments, a sliding block is arranged on the outer side wall of the side, close to the driven gear, of the eyepiece module, a sliding groove is formed in the position, corresponding to the sliding block, of the inner side wall of the screen module, the sliding block is located in the sliding groove, the screen module is further provided with a guide pillar, an arc-shaped hole is formed in the driven gear, the arc-shaped hole extends from the side, close to the side of the eyepiece module, far away from the eyepiece module, and penetrates into the arc-shaped hole.
In this embodiment, at least two arc-shaped protrusions 145 are circumferentially spaced on an outer side wall of the bracket 144 of the screen module 140, and the bracket 144 contacts the driven gear 130 through the two arc-shaped protrusions 145, so that when the driven gear 130 rotates, an inner side wall of the driven gear 130 contacts the arc-shaped protrusions 145, and thus does not contact the entire outer surface of the bracket 144, a contact area can be reduced, and sliding friction between the driven gear 130 and the screen module 140 during rotation can be reduced. In addition, in the present embodiment, two guide pillars 142 are respectively located on two arc-shaped protrusions 145. In addition, in other embodiments, at least two circumferentially separated arc-shaped protrusions may be further provided on an inner sidewall of the driven gear, and the driven gear is in contact with an outer sidewall of the bracket through the at least two arc-shaped protrusions.
In the present embodiment, for saving labor, to facilitate a user to manually adjust the driving gear 120, the rotation speed of the driving gear 120 is greater than the rotation speed of the driven gear 130, and specifically, in the present embodiment, the radius of the driving gear 120 is smaller than the radius of the driven gear 130. The driving gear 120 has a larger angular range of effective engaging teeth on the circumference than the driven gear 130, and the effective engaging teeth refer to the engaging teeth of the driving gear 120 and the driven gear 130 which can be engaged when they rotate. In this embodiment, the driving gear 120 is provided with a circle of teeth on the circumference, and the driven gear 130 is provided with continuous teeth only in a partial region on the circumference, that is, the angular range of the driving gear 120 with effective teeth is 360 degrees, and the angular range of the driven gear 130 with effective teeth is less than 360 degrees, for example, 90 degrees, 120 degrees, 150 degrees, etc., so that the driven gear 130 cannot rotate a complete circle, and thus the potentiometer 150 does not output the same potential signal during the driving gear 120 drives the driven gear 130 to rotate in one direction.
