Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an adjusting mechanism for a mirror according to an embodiment of the present utility model, wherein an adjusting mechanism 000 is used for being installed in a laser projection device, and the adjusting mechanism 000 is used for adjusting a position of the mirror installed in the laser projection device. The adjustment mechanism 000 may include: the cartridge 100, the bracket 200, the adjustment lever 300, and at least one fastener 400.
The cartridge 100 in the adjustment mechanism 000 has a receiving chamber 100a, and at least one adjustment chute D communicating with the receiving chamber 100a within the cartridge 100.
The bracket 200 in the adjustment mechanism 000 may be located within the receiving cavity 100a of the cartridge 100. For a clearer view of the structure of the bracket 200, please refer to fig. 2, fig. 2 is a schematic diagram of the structure of the bracket according to an embodiment of the present utility model. The support 200 in the adjustment mechanism 000 is used to carry the mirror 001. For example, spring tabs 002 may be used to secure the mirror 001 to the mount 200.
The adjusting lever 300 of the adjusting mechanism 000 may be disposed in the accommodating chamber 100a of the case 100. In order to more clearly see the structure of the adjustment mechanism 000, please refer to fig. 2 and 3, fig. 3 is an exploded view of the adjustment mechanism shown in fig. 1, and the adjustment lever 300 in the adjustment mechanism 000 may be fixedly connected to one end of the bracket 200. In one possible implementation, the adjustment lever 300 and the bracket 200 may be of an integral structure, i.e., both are integrally formed structures; in another possible implementation, a locking structure such as a screw or bolt or glue may be used to secure the adjustment lever 300 to one end of the bracket 200.
At least one fastener 400 of the adjusting mechanism 000 is in one-to-one correspondence with at least one adjusting chute D of the case 100 and with at least one end of the adjusting lever 300. Each fastener 400 is adapted to be coupled to a corresponding end of the adjustment lever 300 after passing through a corresponding adjustment chute D.
Wherein each fastener 400 may be configured to: the adjusting rod 300 is fixed in the accommodating cavity 100a after the bracket 200 is rotated in the accommodating cavity 100a and the corresponding adjusting chute D is moved to rotate the bracket 200 around the first axis L1 parallel to the reflecting surface of the reflecting mirror 001 by the adjusting rod 300.
After the adjustment mechanism 000 is fixed in the laser projection device, the mirror 001 carried by the bracket 200 in the adjustment mechanism 000 is located between the optical machine assembly and the light source assembly in the laser projection device. Because the optical machine component and the light source component in the laser projection device are extremely prone to assembly errors, and the reflector 001 located between the optical machine component and the light source component is also prone to assembly errors. Therefore, the laser beam provided by the light source assembly in the laser projection device may not be totally directed to the mirror 001, and the laser beam reflected by the mirror 001 may not be totally directed to the optical machine assembly. Therefore, in order to improve the light-emitting efficiency of the laser projection device, the position of the reflecting mirror 001 between the optical-mechanical assembly and the light source assembly needs to be adjusted by the adjusting mechanism 000, so as to ensure that the laser beam provided by the light source assembly can better enter the optical-mechanical assembly after being reflected by the reflecting mirror 001, and further ensure that the subsequent projection image projected by the projection lens in the laser projection device has better display effect.
For example, as shown in fig. 1, 2 and 3, when it is desired to adjust the position of the mirror 001, an operator can control each fastener 400 to move within the corresponding adjustment chute D. Thus, the fastener 400 can drive the adjusting lever 300 to rotate, so that the adjusting lever 300 can drive the bracket 200 to rotate around the first axis L1 parallel to the reflecting surface of the reflector 001, and further the reflector 001 carried by the bracket 200 can rotate around the first axis L1 in synchronization with the bracket 200. And after the bracket 200 is completely rotated in the receiving chamber 100a of the case 100, an operator may fix the adjustment lever 300 in the receiving chamber 100a of the case 100 by the fastener 400. Therefore, the position of the reflecting mirror 001 can be adjusted, so that the reflecting mirror 001 can be stably kept at the position capable of better reflecting the laser beam provided by the light source assembly to the optical machine assembly. The reflector 001 is not required to be disassembled from the laser projection equipment and reassembled, and the position of the reflector 001 can be adjusted by adjusting the position of the fastener 400 in the adjusting chute D, so that the adjusting process of the position of the reflector 001 is effectively simplified, and the adjusting efficiency of the position of the reflector 001 is improved.
In summary, the present utility model provides an adjusting mechanism of a reflecting mirror, where the adjusting mechanism is used to be installed in a laser projection device, and the adjusting mechanism may include: the device comprises a box body, a bracket, an adjusting rod and at least one fastener. When it is desired to adjust the position of the mirror, an operator can control each fastener to move within the corresponding adjustment chute. Therefore, the fastener can drive the adjusting rod to rotate, so that the adjusting rod can drive the support to rotate around a first axis parallel to the reflecting surface of the reflecting mirror, and further the reflecting mirror borne by the support can synchronously rotate around the first axis with the support. Therefore, the position of the reflecting mirror can be adjusted, so that the reflecting mirror can be stably kept at the position where the laser beam provided by the light source assembly can be better reflected to the optical machine assembly. The reflector is not required to be disassembled from the laser projection equipment and reassembled, the position of the reflector can be adjusted by adjusting the position of the fastener in the adjusting chute, the adjusting process of the position of the reflector is effectively simplified, and the adjusting efficiency of the position of the reflector is improved.
In the embodiment of the present utility model, please refer to fig. 4, fig. 4 is a schematic structural diagram of an adjusting rod according to an embodiment of the present utility model. The adjustment lever 300 in the adjustment mechanism 000 may include: an adjusting lever body 301 fixedly connected to one end of the bracket 200 in the adjusting mechanism 000, and an adjusting post 302 fixedly connected to at least one end of the adjusting lever body 301. Here, at least one adjustment post 302 in adjustment lever 300 is in one-to-one correspondence with at least one fastener 400 in adjustment mechanism 000. Wherein each fastener 400 may be threaded with a corresponding adjustment post 302 after passing through a corresponding adjustment chute D.
For example, please refer to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of another adjusting mechanism provided in an embodiment of the present utility model, and fig. 6 is an exploded view of the adjusting mechanism shown in fig. 5. The end of the adjusting rod 300, to which the adjusting post 302 is connected, is provided with a threaded hole, and the fastener 400 may be provided with a screw rod matched with the threaded hole of the adjusting post 302, and the length of the screw rod is greater than or equal to the sum of the depth of the threaded hole and the depth of the adjusting chute D, so that the screw rod of the fastener 400 may be in threaded connection with the corresponding adjusting post 302 after passing through the corresponding adjusting chute D.
In this manner, the fastener 400 is threadably engaged with the adjustment post 302 to ensure that the fastener 400 does not exert a compressive force on the housing 100 when it is desired to adjust the position of the mirror 001 within the receiving chamber 100a of the cartridge 100. In this case, the fastener 400 moving in the adjusting chute D can drive the adjusting post 302 in the adjusting rod 300 to move synchronously, so that the adjusting rod body 301 in the adjusting rod 300 can rotate around the first axis L1, and further, the adjusting rod body 301 can drive the bracket 200 to rotate synchronously around the first axis L1, so that the bracket 200 can drive the reflector 001 carried by the bracket to rotate synchronously around the first axis L1. In this way, the position of the mirror 001 positioned in the accommodation chamber 100a can be adjusted.
After the position of the reflecting mirror 001 in the accommodating cavity 100a is adjusted, the fastening member 400 can be moved toward the box body 100 by screwing until the fastening member 400 is screwed, so that one surface of the fastening member 400 and one surface of the box body 100 can be tightly attached together, and the fastening member 400 can apply a sufficient pressing force to the box body 100, so that the adjusting column 302 in the adjusting rod 300 is tightly attached to the inner wall of the accommodating cavity 100a of the box body 100. Thus, the adjusting lever 300 can be fixed in the accommodating cavity 100a of the box body 100 by the fastener 400, so that the bracket 200 and the reflecting mirror 001 carried by the bracket 200 can also be fixed in the accommodating cavity 100a, and the reflecting mirror 001 can be stably mounted at a designated position.
In the present utility model, as shown in fig. 5 and 6, the cartridge 100 in the adjustment mechanism 000 may further have a through hole O communicating with the accommodating chamber 100a of the cartridge 100, and the adjustment mechanism 000 may further include: and a rotating member 303 fixedly connected to a side of the adjustment lever body 301 of the adjustment lever 300 facing away from the bracket 200. Wherein the rotating member 303 may be configured to: is engaged with the end of the auxiliary tool 500 inserted from the through hole O.
Thus, when the position of the reflecting mirror 001 needs to be adjusted, the operator can insert the end of the auxiliary tool 500 into the through hole O of the rotating member 303, so that the end of the auxiliary tool 500 can be clamped with the rotating member 303, and then the operator can rotate the auxiliary tool 500, so that the rotating tool drives the rotating member 303 to rotate around the central axis of the through hole O. Here, the central axis of the through hole O may be collinear with the first axis L1. Thus, when the rotating tool drives the rotating member 303 to rotate, the rotating member 303 is fixedly connected with the adjusting lever body 301, so that the rotating member 303 can drive the adjusting lever body 301 to rotate around the first axis L1, and the adjusting lever body 301 can drive the bracket 200 to rotate around the first axis L1.
In this case, in order to improve the position adjustment effect on the mirror 001, it is necessary to ensure that the first axis L1 coincides with the symmetry axis in the longitudinal direction of the mirror 001. For this reason, it is necessary to ensure that the symmetry axis of the mirror 001 in the longitudinal direction is required to be collinear with the central axis of the through hole O.
It should be noted that, when the auxiliary tool 500 drives the rotating member 303 to rotate, the fastening member 400 and the adjusting post 302 in the adjusting rod 300 are also in a threaded connection state, and the fastening member 400 and the adjusting rod 300 can move synchronously. During the process that the auxiliary tool 500 drives the rotating member 303 to rotate, the fastening member 400 moves in the adjusting chute D, and when the fastening member 400 is in a limit position in the adjusting chute D, that is, when the fastening member 400 contacts with the edge of the adjusting chute D, the auxiliary tool 500 cannot rotate due to the resistance from the fastening member 400. In this way, the auxiliary tool 500 can be controlled to adjust the rotation range of the adjusting rod 300 through the cooperation of the fastener 400 and the adjusting chute D, so that the position of the reflecting mirror 001 can be ensured to be adjusted within a certain range, the condition that the position deviation of the reflecting mirror 001 is larger due to overlarge adjusting range is avoided, and the adjusting efficiency of the position of the reflecting mirror 001 is improved.
It should be noted that, referring to fig. 7, fig. 7 is a side view of a box provided by the embodiment of the present utility model, the adjusting chute D on the box 100 may be an arc chute, and the center of the arc chute is located on the central axis of the through hole O of the box 100. Thus, when the operator controls the adjusting lever 300 to rotate around the first axis L1 through the auxiliary tool 500, since the center of the adjusting chute D is located on the central axis of the through hole O and the central axis of the through hole O coincides with the first axis L1, the fastener 400 located in the adjusting chute D can rotate around the central axis of the through hole O, so that the fastener 400 and the adjusting lever 300 can rotate around the first axis L1 in synchronization.
In the embodiment of the present utility model, there are various possible implementations of the clamping connection between the end of the auxiliary tool 500 and the rotating member 303, and the following two alternative implementations of the embodiment of the present utility model are schematically illustrated as examples:
referring to fig. 8, fig. 8 is a schematic diagram of a cooperation between a rotating member and an auxiliary tool according to an embodiment of the present utility model, a side of the rotating member 303 facing away from the adjusting rod body 301 has a rotation adjusting hole a communicating with the through hole O, and a cross section of the rotation adjusting hole a is in a non-circular arbitrary shape. For example, the cross-section of the rotation adjusting hole a is hexagonal in shape. The shape of the rotation adjusting hole a matches the shape of the end of the auxiliary tool 500, and the end of the auxiliary tool 500 can be inserted into the rotation adjusting hole a.
By way of example, the auxiliary tool 500 may include: the handle piece 501, and the connecting rod 502 fixedly connected with the handle piece 501, the length of the connecting rod 502 of the auxiliary tool 500 is larger than the sum of the depth of the through hole O and the depth of the rotation adjusting hole a, and the shape of the end of the connecting rod 502 facing away from the handle piece 501 matches with the shape of the rotation adjusting hole a. Like this, the connecting rod 502 of appurtenance 500 deviates from the tip of handle piece 501 and can inserts in the rotation regulation hole A, with the rotation piece 303 joint in the regulation pole 300, and the operating personnel can drive connecting rod 502 through the handle piece 501 of appurtenance 500 and rotate, and then make connecting rod 502 can drive the rotation piece 303 rotation rather than the joint.
Referring to fig. 9, fig. 9 is a schematic diagram of another embodiment of the present utility model, in which the rotating member 303 is provided with a clamping protrusion B on a side facing away from the adjusting rod body 301, and the cross section of the clamping protrusion B is in a non-circular arbitrary shape. For example, the cross-section of the engaging protrusion B is hexagonal in shape. Here, the end of the auxiliary tool 500 has a clamping groove C that mates with a clamping protrusion B, the shape of which matches the shape of the clamping groove C of the auxiliary tool 500, and the clamping protrusion B may be located in the clamping groove C.
By way of example, the auxiliary tool 500 may include: the handle piece 501, and the connecting rod 502 fixedly connected with the handle piece 501, the length of the connecting rod 502 of the auxiliary tool 500 is larger than the sum of the depth of the through hole O and the thickness of the clamping protrusion B, and the clamping groove C is positioned at the end of the connecting rod 502 facing away from the handle piece 501. Like this, the connecting rod 502 of appurtenance 500 deviates from the tip of handle piece 501 and can inserts through-hole O, with the protruding B joint of rotating member 303 in adjusting the pole 300, and the operating personnel can drive connecting rod 502 through the handle piece 501 of appurtenance 500 and rotate, and then make connecting rod 502 can drive the rotating member 303 of its joint rotate.
In the embodiment of the present utility model, referring to fig. 5 and 6, the length direction of the adjusting rod body 301 in the adjusting rod 300 may intersect the reflecting surface of the reflecting mirror 001. Illustratively, the length direction of the adjustment lever body 301 in the adjustment lever 300 is perpendicular to the reflecting surface of the reflecting mirror 001.
The cartridge 100 may have two adjustment runners D and the adjustment mechanism 000 may include two fasteners 400. Wherein, the two fasteners 400 respectively pass through the two adjusting sliding grooves D in the box body 100 and then are connected with two opposite ends of the adjusting rod 300. In this case, the adjustment lever 300 may include two adjustment posts 302, the two adjustment posts 302 being respectively fixed to two oppositely disposed ends of the adjustment lever body 301 in the adjustment lever 300, and the two adjustment posts 302 may be respectively screwed with the two fasteners 400 in the adjustment mechanism 000.
It should be noted that, when the box body 100 has two adjusting sliding grooves D, the through hole O of the box body 100 may be located between the two adjusting sliding grooves D. In this way, when the auxiliary tool 500 inserted from the through hole O rotates the rotating member 303 in the adjustment lever 300, the two fastening members 400 in the adjustment mechanism 000 can be moved in the two adjustment slide grooves D, respectively, so that the two support columns 303 in the adjustment lever 300 can be moved in synchronization. Because the adjusting chute D is an arc chute, and the center of the arc chute is positioned on the central axis of the through hole O. Therefore, when the two fasteners 400 move in the two adjusting sliding grooves D, the two fasteners 400 can rotate around the central axis of the through hole O, so that the two fasteners 400 can drive the two support columns 303 to synchronously rotate around the central axis of the through hole O, and further the adjusting rod 300 can synchronously rotate around the central axis of the through hole O more stably.
Here, two fasteners 400 in adjustment mechanism 000 may be configured to: after the adjusting rod 300 is fixed in the accommodating cavity 100a of the box body 100, the two ends of the adjusting rod 300 are relatively displaced in the direction parallel to the first axis L1, so as to drive the bracket 200 to rotate around the second axis L2 parallel to the reflecting surface of the reflecting mirror 001 and perpendicular to the first axis L1.
Illustratively, after the fastener 400 secures the adjustment lever 300 within the receiving cavity 100a of the case 100, the fastener 400 is in a tightened state. Since the adjusting post 302 at the end of the adjusting lever 300 is closely attached to the case 100 by the pressing force provided by the fastener 400, the adjusting post 302 is elastically deformed and stores the elastic force. When it is necessary to adjust the position of the mirror 001 with respect to the second axis L2 direction, one fastener 400 of the two fasteners 400 may be unscrewed as necessary, and it is also necessary to ensure that the fasteners 400 do not move in the axial direction. During this process, the adjustment column 302 corresponding to this fastener 400 may release a portion of the spring force and the previously compressed portion of this adjustment column 302 may gradually recover, but not return to an uncompressed state. In this way, the two adjusting posts 302 in the adjusting lever 300 can generate relative displacement in the direction parallel to the first axis L1, so as to drive the two ends of the adjusting lever body 301 in the adjusting lever 300 to generate relative displacement in the direction parallel to the first axis L1. Further, the length direction of the adjusting lever body 301 is perpendicular to the reflecting surface of the reflecting mirror 001. Therefore, when the both end portions of the adjustment lever body 301 are relatively displaced in a direction parallel to the first axis L1, the bracket 200 coupled to the adjustment lever body 301 can be rotated about the second axis L2 parallel to the reflection surface of the mirror 001 and perpendicular to the first axis L1. Here, the second axis L2 is located at a side of the bracket 200 near the adjustment lever body 301.
In this case, not only the mirror 001 can be rotated about the first axis L1 but also the mirror 001 can be rotated about the second axis L2 by the adjusting mechanism 000, so that the angle between the mirror 001 and the inner wall of the case 100 can be changed. Therefore, the reflecting mirror 001 can be better adjusted to a position capable of better reflecting the laser beam provided by the light source assembly to the optical machine assembly.
In the present utility model, the above embodiments are described with reference to the two fastening members 400, and other possible implementations are provided in the embodiments of the present utility model, please refer to fig. 10 and fig. 11, fig. 10 is a schematic structural diagram of another adjusting mechanism provided in the embodiment of the present utility model, and fig. 11 is an exploded view of the adjusting mechanism shown in fig. 10. The number of the fasteners 400 in the adjusting mechanism 000 may be three, in which case the number of the adjusting chute D and the adjusting column 302 in the adjusting lever 300 may be three, and thus, the fasteners 400 in the adjusting mechanism 000 may each be in one-to-one correspondence with one adjusting chute D and may be in one-to-one correspondence with the adjusting column 302.
Optionally, the distances between the three fasteners 400 and the through hole O are consistent, that is, the three fasteners 400 are all located on a circle with the through hole O as a center, so that each fastener 400 can synchronously move in the adjusting chute D in the process that the auxiliary tool 500 drives the rotating member 303 to rotate, and the situation that part of fasteners in each fastener 400 cannot rotate again after reaching the limit position in advance is avoided.
Alternatively, three fasteners 400 may be configured to: after the adjusting rod 300 is fixed in the accommodating cavity 100a of the case 100, the two ends of the adjusting rod 300 are relatively displaced in the direction parallel to the first axis L1, so as to change the included angle between the reflecting mirror 001 and the inner wall of the case 100. Here, the adjustment manner of the angle between the reflecting mirror 001 and the inner wall of the box body 100 by the three fasteners may refer to the adjustment manner of the two fasteners 400, which is not described herein. Compared with the adjusting mechanism 000 using two fasteners 400, the adjusting mechanism 000 using three fasteners 400 has better stability in the process of adjusting the position of the reflecting mirror 001 and the included angle between the reflecting mirror 001 and the inner wall of the box body 100, and can ensure that the bracket 200 cannot be misplaced due to interference of external environment in the adjusting process.
In an embodiment of the present utility model, please refer to fig. 12, fig. 12 is a schematic structural diagram of another adjusting mechanism provided in an embodiment of the present utility model, and the adjusting mechanism 000 may further include: the fastening gel 600, the fastening gel 600 may be configured to: after the bracket 200 is rotated about the second axis L2, the fastener 400 and the case 100 are bonded.
