[0047] Based on the related art, the spatial attitude of the optical instrument is manually adjusted to accurately receive the light spot to be detected, and the adjustment accuracy is low, and it is difficult to be applied to optical instruments with large volume and mass. The deflection adjustment device provided in the present application can adjust the spatial attitude of the optical instrument with large volume and mass, and has relatively accurate adjustment accuracy.

[0048] Referring to Figure 1 and Figure 2 As shown, the deflection adjustment device 10 includes a fixing member 100, a bearing member 200, and a connecting assembly 300, in combination with Figure 3 As shown, the bearing member 200 is used to bear the optical instrument 20, and the bearing member 200 and the fixing member 100 are sequentially arranged along a first direction F1. The connecting assembly 300 is connected between the fixing member 100 and the bearing member 200, so that the bearing member 200 can rotate relative to the fixing member 100 about a first axis parallel to a second direction F2, and the bearing member 200 can rotate relative to the fixing member 100 about a second axis parallel to a third direction F3. Wherein, the first direction F1, the second direction F2 and the third direction F3 intersect with each other. Thus, the bearing member 200 rotates relative to the fixing member 100 about the axis, at the same time, drives the adjustment of the spatial attitude of the optical instrument 20, so that the optical instrument 20 accurately receives the external light beam.

[0049] The deflection adjusting device 10 of the present application enables the carrier 200 to rotate relative to the fixed part 100 around the first axis and to rotate relative to the fixed part 100 around the second axis through the connecting assembly 300, and the carrier 200 is used to carry the optical instrument 20, so as to drive the optical instrument 20 to realize two-dimensional adjustment, and then adjust the spatial posture of the optical instrument 20, so that the optical instrument 20 accurately receives the external light beam. Compared with manual adjustment, the present application improves the convenience of adjusting the posture of the optical instrument 20. Moreover, the present application can adjust the spatial posture of the optical instrument 20 with large volume and mass, and has relatively accurate adjustment precision.

[0050] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , the connecting assembly 300 includes a plurality of pre-tightening members 310 connected between the fixed part 100 and the carrier 200, so that the carrier 200 is connected to the fixed part 100 while the carrier 200 can move within a preset range of displacement away from the fixed part 100, that is, the carrier 200 and the fixed part 100 are not strictly locked and have a certain activity space therebetween. It can be understood that the pre-tightening member 310 serves to connect the fixed part 100 and the carrier 200, and at the same time, the pre-tightening member 310 does not affect the relative movement between the carrier 200 and the fixed part 100 within the preset range, that is, it does not affect the rotation of the carrier 200 relative to the fixed part 100 around the first axis, nor does it affect the rotation of the carrier 200 relative to the fixed part 100 around the second axis. Thus, the movement of the carrier 200 relative to the fixed part 100 can be realized, and then the optical instrument 20 is driven to move, the spatial posture of the optical instrument 20 is adjusted, and it accurately receives the external light beam.

[0051] In some embodiments, the pre-tightening member 310 can be a spring bolt, which includes a pre-tightening screw and an elastic member. The pre-tightening screw is arranged along the first direction F1 through the fixed part 100 and the carrier 200 to connect the fixed part 100 and the carrier 200. The elastic member can be a spring, which is sleeved on the pre-tightening screw, located on the side of the fixed part 100 away from the carrier 200, and abuts between the fixed part 100 and the pre-tightening screw, or in other words, the elastic member is arranged between the end of the pre-tightening screw away from the carrier 200 and the side of the fixed part 100 away from the carrier 200. To provide a pre-tightening force of the fixed part 100 towards the carrier 200. The pre-tightening member 310 can also be other structures that can be connected and have a certain activity space between the fixed part 100 and the carrier 200, which is not limited here.

[0052] In some embodiments, as Figure 1 、 Figure 2 and Figure 3As shown, the connecting assembly 300 further comprises a first adjusting rod 320, which is arranged through the fixing member 100 along the first direction F1 and abuts against a side of the bearing member 200 away from the first axis, or in other words, the first adjusting rod 320 is arranged at a side of the pre-tightening member 310 along the second direction F2, and the first adjusting rod 320 is arranged to be movable relative to the fixing member 100 along the first direction F1 to drive the bearing member 200 to rotate around the first axis. That is, by adjusting the first adjusting rod 320 to move along the first direction F1, a pushing force is provided to a position of the bearing member 200 in contact with the first adjusting rod 320, so that the bearing member 200 can rotate relative to the fixing member 100 around the first axis parallel to the second direction F2, thereby achieving adjustment of the spatial posture of the bearing member 200 in the first dimension, and further adjusting the spatial posture of the optical instrument 20 by the first adjusting rod 320 without manual moving, which is conducive to improving the adjustment convenience and the adjustment accuracy, and is applicable to adjustment of the optical instrument 20 with large volume and mass.

[0053] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the connecting assembly 300 further comprises a second adjusting rod 330, which is arranged through the fixing member 100 along the first direction F1 and abuts against a side of the bearing member 200 away from the second axis. The second adjusting rod 330 is arranged to be movable relative to the fixing member 100 along the first direction F1 to drive the bearing member 200 to rotate around the second axis. That is, by adjusting the second adjusting rod 330 to move along the first direction F1, a pushing force can be provided to a position of the bearing member 200 in contact with the second adjusting rod 330, so that the bearing member 200 can rotate relative to the fixing member 100 around the second axis parallel to the third direction F3, thereby achieving adjustment of the spatial posture of the bearing member 200 in the second dimension, and further adjusting the spatial posture of the optical instrument 20 by the second adjusting rod 330 without manual moving, which is conducive to improving the adjustment accuracy, and is applicable to adjustment of the optical instrument 20 with large volume and mass.

[0054] The first adjusting rod 320 and the second adjusting rod 330 cooperate to achieve adjustment of the spatial posture of the bearing member 200 and the optical instrument 20 carried thereby in two spatial dimensions, which is conducive to improving the adjustment convenience. Further, the deflection adjusting device 10 is applicable to adjustment of the optical instrument 20 with large volume and mass, and is conducive to further improving the accuracy of receiving the external light beam by the optical instrument 20, and is applicable to adjustment of the optical instrument 20 with large volume and mass relative to the low upper limit of the manual bearing force.

[0055] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3As shown, the connecting assembly 300 further comprises a ball 360 arranged between the fixed member 100 and the bearing member 200, and the ball 360 is arranged on the fixed member 100 close to one side of the intersection of the first axis and the second axis. The side of the fixed member 100 facing the bearing member 200 is provided with a first limiting groove, and the side of the bearing member 200 facing the fixed member 100 is provided with a second limiting groove opposite to the first limiting groove, and the first limiting groove and the second limiting groove are used to accommodate the ball 360, or in other words, the ball 360 is limited between the first limiting groove and the second limiting groove, so that the ball 360 can roll relative to the fixed member 100 and can roll relative to the bearing member 200.

[0056] It can be understood that the ball 360 acts as a fulcrum, and the ball 360 cooperates with the first adjusting rod 320, so that when the bearing member 200 rotates relative to the fixed member 100 about an axis parallel to the second direction F2, the axis is defined on the second axis and does not change. Correspondingly, the ball 360 cooperates with the second adjusting rod 330, so that when the bearing member 200 rotates relative to the fixed member 100 about an axis parallel to the third direction F3, the axis is defined on the second axis and does not change. Further, the ball 360 can cooperate with the first adjusting rod 320 and the second adjusting rod 330, which is conducive to further improving the accuracy of the rotation adjustment of the bearing member 200 relative to the fixed member 100, improving the accuracy of the spatial attitude adjustment of the optical instrument 20, and accurately receiving the external light beam by the optical instrument 20.

[0058] It can be understood that the line between the ball 360 and the first rolling member coincides with the second axis, and when the bearing member 200 rotates relative to the fixed member 100 about the second axis, the first rolling member acts as another fulcrum on the second axis and does not wear the bearing member 200. At the same time, the ball 360 and the first rolling member simultaneously act as fulcrums on the second axis, which can make the fixed member 100 and the bearing member 200 flexibly rotate relative to each other, and is conducive to improving the convenience of the rotation of the bearing member 200 relative to the fixed member 100 about the second axis.

[0059] In some embodiments, the first end of the first adjusting rod 320 towards the bearing member 200 is provided with a first rolling member, the first rolling member abuts on the bearing member 200, and the first rolling member is arranged to be able to roll relative to the first adjusting rod 320, and the first rolling member is arranged to be able to roll relative to the bearing member 200. In some embodiments, the first rolling member is a ball structure.

[0060] It can be understood that the connecting line between the ball 360 and the second rolling member coincides with the first axis, and when the bearing member 200 rotates relative to the fixed member 100 around the first axis, the second rolling member serves as another fulcrum on the first axis and does not wear the bearing member 200. Meanwhile, the ball 360 and the second rolling member simultaneously serve as the fulcrum on the first axis, so that the fixed member 100 and the bearing member 200 can flexibly rotate relative to each other, which is beneficial to improve the convenience of the rotation of the bearing member 200 relative to the fixed member 100 around the first axis.

[0061] In some embodiments, the bearing member 200 is provided with a first groove on the side facing the first rolling member, the first rolling member is limited in the first groove, and the first rolling member is arranged to be able to roll relative to the bearing member 200. Through the arrangement of the first groove, the first rolling member can be limited, the stability of the first rolling member during movement is improved, and thus the stability of the rotation movement of the bearing member 200 relative to the fixed member 100 around the second axis is improved, which is beneficial to further improve the stability of the space attitude adjustment of the optical instrument by the present application.

[0062] In some embodiments, the bearing member 200 is provided with a second groove on the side facing the second rolling member, the second rolling member is limited in the second groove, and the second rolling member is arranged to be able to roll relative to the bearing member 200. It can be understood that the second rolling member can be limited through the second groove, the stability of the second rolling member during movement is improved, and thus the stability of the rotation movement of the bearing member 200 relative to the fixed member 100 around the first axis is improved, which is beneficial to further improve the stability of the space attitude adjustment of the optical instrument by the present application.

[0064] When the first adjusting rod 320 pushes the carrier 200 to rotate around the second axis to a preset position or a suitable position, the optical instrument 20 has been adjusted to a suitable position in this dimension. Then, the first locking screw 343 can be locked to clamp the first clamping piece 341 and the second clamping piece 342 to the first adjusting rod 320, and a part of the first adjusting rod 320 is stably supported between the carrier 200 and the fixed part 100, so that the carrier 200 is maintained at the preset position relative to the fixed part 100, thereby keeping the optical instrument 20 in a stable position in this dimension, which is conducive to further improving the adjustment accuracy.

[0071] In some embodiments, referring to Figure 1 and Figure 5 , the alignment assembly 500 comprises an alignment sleeve 510, a sealing ring 520 and a pressing nut 530, the alignment sleeve 510 defines a light transmission path in the alignment sleeve 510, and the alignment sleeve 510 is used to extend into the receiving port, so that the external light beam can enter the receiving port through the light transmission path, thereby accurately entering the optical instrument 20.

[0072] The sealing ring 520 and the extrusion nut 530 are sleeved on the alignment sleeve 510, and the extrusion nut 530 is threadedly connected with the alignment sleeve 510, so that the extrusion nut 530 moves relative to the alignment sleeve 510 towards the sealing ring 520 and extrudes the sealing ring 520, so that the radial dimension of the sealing ring 520 is increased, and the sealing ring 520 can abut against the side wall of the receiving port. It can be understood that the alignment sleeve 510 plays a guiding role, which is beneficial to the relative position of the alignment assembly 500 and the receiving port. The sealing ring 520 is extruded by the extrusion nut 530, so that the radial dimension of the sealing ring 520 can be changed, and the radial dimension of the sealing ring 520 is increased. For the optical instrument 20 with a larger receiving port, the extrusion nut 530 extrudes the sealing ring 520 to increase the radial dimension of the sealing ring 520, so that the sealing ring 520 abuts against the inner wall of the receiving port, thereby facilitating the alignment of the alignment sleeve 510 with the receiving port, the centering of the cylinder axis of the alignment sleeve 510 relative to the receiving port, and the accurate entry of the external light beam into the receiving port.

[0073] After the alignment assembly 500 is adjusted to make the external light beam accurately enter the receiving port, the alignment assembly 500 is separated from the receiving port, and the alignment assembly 500 is removed from the window of the alignment plate 400. Then, the next more accurate adjustment of the carrier 200 relative to the fixing part 100 is performed by the connecting assembly 300. The alignment plate 400 and the alignment assembly 500 are used to preliminarily adjust the entry of the external light beam into the optical instrument 20, so that the external light beam preliminarily enters the optical instrument 20 and smoothly irradiates on the internal element of the optical instrument 20, thereby improving the use convenience of the deflection adjustment device 10.

[0074] In some embodiments, continuing to refer to Figure 1 As shown, the carrier 200 includes a connecting part 210 and a carrying part 220, the connecting assembly 300 is connected between the fixing part 100 and the connecting part 210, and the carrying part 220 is arranged on the side of the connecting part 210 away from the fixing part 100 and is used for carrying the optical instrument 20. That is, the carrier 200 is a plate material in the shape of “L”, when the connecting part 210 is adjusted to rotate relative to the fixing part 100, the carrying part 220 and the optical instrument 20 on the carrying part 220 are synchronously rotated. The arrangement of the carrying part 220 is beneficial to the carrier 200 to carry the optical instrument 20 with large mass, and is beneficial to the deflection adjustment device 10 of the present application to be applicable to the adjustment of the spatial posture of the optical instrument 20 with large volume and mass.

[0075] In some embodiments, the alignment plate 400 and the fixing part 100 are fixed to each other, and a connecting structure for fixing with an external device is arranged on the alignment plate 400, so that the alignment plate 400 and the fixing part 100 can be detachably connected with the external device through the connecting structure. The connecting structure can be composed of a bolt or a screw and the like.

[0076] The deflection adjusting device 10 of the present application enables the carrier 200 to rotate around the first axis relative to the fixed part 100 and to rotate around the second axis relative to the fixed part 100 through the connecting assembly 300, and the carrier 200 is used to carry the optical instrument 20, so as to drive the optical instrument 20 to realize two-dimensional adjustment, and then adjust the spatial posture of the optical instrument 20, so that the optical instrument 20 can accurately receive the external light beam. Compared with manual adjustment, the present application can adjust the spatial posture of the optical instrument 20 with large volume and mass, and has relatively accurate adjustment accuracy.

[0077] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0078] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
