Description

[0002] In optical instruments, various optical elements such as light sources, optical lenses, and diaphragms are usually placed in the same housing to achieve both dust-proof and aesthetic effects. However, during the manufacturing, assembly, and debugging processes of optical instruments, due to welding errors of light source emitters, machining errors of mounting parts, and vibrations during use, etc., the position of the light source after installation is not the theoretical calculated position in optical design. For precision optical instruments, there are strict requirements for the irradiation angle and irradiation distance of the light source, so it is necessary to finely adjust the installation position of the light source.

[0003] In related technologies, the position of the light is usually adjusted by first disassembling the housing of the optical instrument and then sequentially adjusting the positions of each adjusting part.

[0090] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only one embodiment of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0093] In addition, unless otherwise clearly defined and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0094] In an optical instrument, generally, various optical elements such as a light source, an optical lens, a diaphragm, etc. are placed in the same housing to achieve both dust-proof and aesthetic effects. However, during the manufacturing, assembly, and debugging processes of the optical instrument, due to the welding error of the light-emitting body of the light source, the machining error of the mounting parts, and the vibration during use, etc., the position of the light source after installation is not the theoretical calculation position in the optical design. For precision optical instruments, there are strict requirements for the irradiation angle and irradiation distance of the light source, so it is necessary to finely adjust the installation position of the light source. In the related art, usually, the housing of the optical instrument is first opened, and then the positions of each adjusting part are sequentially adjusted to adjust the light position. However, the operation process of this position adjustment method is relatively complicated, and the independent setting of the adjusting parts occupies a relatively large internal space of the device.

[0095] In view of this, the present invention provides a position adjustment device and an optical device to solve at least one of the technical problems existing in the light adjustment method in the related art, such as the complex operation process and the large internal space occupied by the independently arranged adjustment parts.

[0096] As Figures 1 to 11 shown, the present invention provides a position adjustment device, including a housing 10 and an adjustment mechanism located inside the housing 10. The adjustment mechanism is used to adjust the position of a light source built in the housing 10. A position adjustment hole is provided on the housing 10, and through the position adjustment hole, the internal adjustment mechanism can be directly operated outside the housing 10 to realize the adjustment of the position of the light source in the housing 10.

[0097] The adjustment mechanism includes an angle adjustment component 20, a first adjustment component 30, and a second adjustment component 40 which are nested. Optionally, the nested setting here refers to the combination method in which the components are wrapped layer by layer. Correspondingly, the position adjustment hole can include at least three adjustment holes, and these adjustment holes correspond to the angle adjustment component 20, the first adjustment component 30, and the second adjustment component 40 respectively.

[0098] In this embodiment, continuing as Figure 1 shown, the housing 10 includes an upper cover 11 and a bottom shell 12. The position adjustment hole can include a first adjustment hole 13, a second adjustment hole 14, and a third adjustment hole 15. Specifically, two side edges of the bottom shell 12 are respectively provided with the first adjustment hole 13 corresponding to the angle adjustment component 20 and the second adjustment hole 14 corresponding to the first adjustment component 30, and the upper cover 11 is provided with the third adjustment hole 15 corresponding to the second adjustment component 40.

[0099] It should be understood that the opening positions, shapes, and sizes of the first adjustment hole 13, the second adjustment hole 14, and the third adjustment hole 15 match the corresponding angle adjustment component 20, first adjustment component 30, and second adjustment component 40 respectively.

[0100] Among them, the angle adjustment component 20 is configured to be fixedly connected to the light source component 50, and the angle adjustment is realized through the position adjustment hole, so as to drive the emitted light of the light source component 50 arranged on the angle adjustment component 20 to rotate within the plane where the first direction is located. Specifically, the first adjustment hole 13 is used to assist the angle adjustment component 20 to realize the angle adjustment outside the housing 10, so as to drive the emitted light of the light source component 50 arranged on the angle adjustment component 20 to rotate within the plane where the first direction is located. That is, the angle adjustment of the emitted light of the light source component 50 is realized outside the housing 10 through the combination of the angle adjustment and the first adjustment hole 13. Optionally, the light source component 50 may at least include a light source element 51. Exemplarily, the light source element 51 may include, but is not limited to, an LED light source of at least one wavelength. The first direction may be a suitable direction relative to the housing 10, such as the vertical direction, and the plane where the first direction is located may be a vertical plane.

[0101] The first adjustment component 30 is configured to realize the movement adjustment in the second direction through the position adjustment hole, so as to drive the emitted light of the light source component 50 to move in the second direction; there is an included angle between the second direction and the first direction. Specifically, the second adjustment hole 14 is used to assist the first adjustment component 30 to realize the movement adjustment outside the housing 10, so as to drive the emitted light of the light source component 50 to move in the second direction. That is, the movement adjustment of the emitted light of the light source component 50 in the second direction is realized outside the housing 10 through the combination of the first adjustment component 30 and the second adjustment hole 14. Optionally, the second direction may be a suitable direction having an included angle with the first direction. Exemplarily, taking the first direction as the vertical direction and the included angle as a right angle as an example, the second direction may be the horizontal direction.

[0102] The second adjustment component 40 is configured to realize the movement adjustment in the first direction through the position adjustment hole, so as to drive the emitted light of the light source component 50 to move in the first direction. Specifically, the third adjustment hole 15 is used to assist the second adjustment component 40 to realize the movement adjustment outside the housing 10, so as to drive the emitted light of the light source component 50 to move in the first direction. That is, the movement adjustment of the emitted light of the light source component 50 in the first direction is realized outside the housing 10 through the combination of the second adjustment component 40 and the third adjustment hole 15.

[0103] In the above embodiments, through multiple nested adjustment components and in cooperation with the position adjustment holes on the housing 10, the rapid adjustment of the position of the light source in the three dimensions of angle, horizontal and vertical can be realized outside the housing 10 of the light source assembly 50, without disassembling the outer shell of the optical instrument to adjust each adjustment part in turn, which simplifies the operation process of position adjustment, improves the operation efficiency and reduces the adjustment time. In addition, compared with the stacked structure, the adjustment mechanism of the present invention adopts a structure of mutual nesting and wrapping, which not only has a more compact structure and high space utilization rate, but also has higher reliability and better stability.

[0104] In this embodiment, as Figures 2 - 4 and Figure 5A shown, the first adjustment component 30 is sleeved outside the angle adjustment component 20, and the second adjustment component 40 is sleeved outside the first adjustment component 30. Specifically, in the adjustment mechanism, at least part of the components are wrapped layer by layer in the order of the angle adjustment component 20, the first adjustment component 30 and the second adjustment component 40 from the inside to the outside to form an adjustment mechanism with a specific shape. Exemplarily, the specific shape can be, but is not limited to, a cube, a cuboid, etc.

[0105] Of course, in some other embodiments, the angle adjustment component 20, the first adjustment component 30 and the second adjustment component 40 can be combined in other nested forms. Exemplarily, the angle adjustment component 20 is sleeved outside the first adjustment component 30, and the second adjustment component 40 is sleeved outside the angle adjustment component 20. Another exemplarily, the second adjustment component 40 is sleeved outside the angle adjustment component 20, and the first adjustment component 30 is sleeved outside the second adjustment component 40.

[0106] It should be noted that in the process of adjusting the outgoing light of the light source assembly 50 through the adjustment mechanism, the adjustment can be carried out in the first adjustment order of the angle adjustment component 20, the first adjustment component 30 and the second adjustment component 40, that is, the angle adjustment is first performed, and then the movement adjustments in the second direction and the first direction are performed in turn. Of course, the whole adjustment process can also be carried out in other suitable adjustment orders, such as first performing the angle adjustment, and then performing the movement adjustments in the first direction and the second direction, etc. For the convenience of description, the embodiments of the present application mainly take this first adjustment order as an example for illustration.

[0107] In an alternative embodiment, as Figure 6As shown, the angle adjustment assembly 20 includes a first end portion 21 and a second end portion 22 which are oppositely arranged. Among them, an angle adjustment member 211 adapted to the first adjustment hole 13 is provided on the first end portion 21; the second end portion 22 is configured to carry the light source assembly 50, and the angle adjustment member 211 is configured to convert the force acting on the angle adjustment member 211 into a force for rotating the light source assembly 50; the adjustment mechanism is provided with a light outlet corresponding to the outgoing light path of the light source assembly 50 for light to exit, so as to ensure that the outgoing light of the light source assembly 50 is not blocked by the adjustment mechanism.

[0108] Specifically, the second end portion 22 is provided with a carrier platform for carrying the light source assembly 50, and the light source assembly 50 is fixed on the carrier platform through connecting members such as bolts. The angle adjustment member 211 can be a connecting convex portion of the first end portion 21, and the position of the angle adjustment member 211 matches the position of the first adjustment hole 13 on the housing 10, so that the angle adjustment tool can pass through the first adjustment hole 13 and act on the angle adjustment member 211 to convert the force acting on the angle adjustment member 211 into a force for rotating the light source assembly 50, thereby realizing the angle adjustment of the outgoing light of the light source assembly 50.

[0109] In an alternative embodiment, as Figure 5A 、 Figure 5B and Figure 6 shown, the angle adjustment assembly 20 further includes a transition portion 23 located between the first end portion 21 and the second end portion 22. Along the first direction, the cross-sectional dimensions of both the first end portion 21 and the second end portion 22 are larger than the cross-sectional dimension of the transition portion 23.

[0110] Specifically, when the angle adjustment assembly 20 further includes a transition portion 23 located at the middle position, the transition portion 23 can connect the first end portion 21 and the second end portion 22 into a fixed block. Along the Figure 5B first direction M therein, the cross-sectional dimensions of both the first end portion 21 and the second end portion 22 are larger than the cross-sectional dimension of the transition portion 23, that is, there is a gap between the transition portion 23 and the first adjustment assembly 30, so that the overall angle adjustment assembly 20 is in an "I" shape. In this way, during the angle adjustment process of the angle adjustment assembly 20, the contact surface between the angle adjustment assembly 20 and the first adjustment assembly 30 wrapped outside it can be reduced, and the friction and wear can be reduced.

[0111] In an alternative embodiment, continue as Figure 5BAs shown, an angle adjustment groove (not shown) corresponding to the first adjustment hole 13 is provided on the angle adjustment member 211. Specifically, during the angle adjustment process, the angle adjustment tool passes through the first adjustment hole 13 on the housing 10 and contacts the angle adjustment groove corresponding to the position of the first adjustment hole 13. The angle adjustment tool performs operations such as clockwise rotation and counterclockwise rotation in the angle adjustment groove, and the force acting on the angle adjustment member 211 can be converted into the acting force for rotating the light source assembly 50, so as to realize the angle adjustment of the outgoing light of the light source assembly 50. In this embodiment, in order to expand the operation space of the angle adjustment tool for the angle adjustment groove, the first adjustment hole 13 is preferably an oblong hole. Optionally, the angle adjustment member 211 can be an angle adjustment knob.

[0112] In an alternative embodiment, as Figure 1 、 4 shown in FIG. 6, the position adjustment device further includes at least one angle fastener (not shown). The housing 10 is further provided with at least one mating through hole 16 adapted to be penetrated by at least one angle fastener, and at least one angle fastening hole 311 matching the at least one angle fastener is provided on the first adjustment assembly 30.

The mating through hole 16 provided on the housing 10 can be a smooth hole, and the diameter of the mating through hole 16 is larger than the size of the angle fastener, so that the angle fastener can completely pass through the mating through hole 16 and enter the interior of the housing 10.

The number of the mating through holes 16 is one or more, and the number of the angle fastening holes 311 matches the number of the mating through holes 16.

[0114] After the angle adjustment component 20 achieves angle adjustment, an angle fastener can pass through the mating through hole 16 and be placed into the angle fastening hole 311. Through the threaded fit between the angle fastener and the angle fastening hole 311, the angle fastener can at least partially press above the angle adjustment member 211 or be clamped on the side of the angle adjustment member 211, so as to fix the angle adjustment member 211 on the first adjustment component 30, realizing the limit fixation of the light source component 50 after angle adjustment. In addition, by fixing the angle adjustment mechanism carrying the light source component 50 on the first adjustment component 30, it is convenient to convert the movement adjustment of the first adjustment component 30 into the second-direction movement adjustment of the light source component 50 subsequently.

[0115] In an alternative embodiment, as Figure 1 , 3 , 8, and 9B show, the position adjustment hole includes a second adjustment hole 14, and the first adjustment component 30 includes a first mounting bracket 31, a first guide member 32, a first elastic member 33, and a first adjustment member (not shown).

[0116] Among them, the first mounting bracket 31 is sleeved outside the angle adjustment component 20, and the first mounting bracket 31 is provided with a hole 312. The first guide member 32 penetrates through the hole 312 and extends into the second adjustment component 40, and the first guide member 32 is slidably connected to the first mounting bracket 31. The first elastic member 33 is disposed between the first end of the first mounting bracket 31 and the second adjustment component 40. The first adjustment member can pass through the second adjustment hole 14 and abut against the second end of the first mounting bracket 31. The first adjustment member is configured to cooperate with the elastic force of the first elastic member 33 to drive the light source component 50 on the angle adjustment component 20 to move along the direction of the first guide member 32 through the first mounting bracket 31.

[0117] Specifically, the first mounting bracket 31 wraps outside the angle adjustment component 20.

The first mounting bracket 31 has a first end and a second end near the first opening, and the first end and the second end are respectively disposed on both sides of the first opening. The first mounting bracket 31 is provided with a hole 312 extending from the first end to the second end. The first guide member 32 can penetrate through the hole 312 and extend into the interior of the second adjustment component 40. At least one end of the first guide member 32 is fixedly connected to the second adjustment component 40, that is, the first guide member 32 has the dual functions of guiding and connecting the first adjustment component 30 and the second adjustment component 40. Exemplarily, one end of the first guide member 32 can be fixed to the second adjustment component 40, and the other end is not fixed to the second adjustment component 40.

[0118] After the angle adjustment component 20 realizes angle adjustment, one end of the angle fastener can be placed in the angle fastening hole 311 through the mating through hole 16 by using a tool, and the other end of the angle fastener abuts against and connects the first mounting bracket 31 and the angle adjustment component 20.

The first elastic member 33 is located in this gap, and at least one end of the first elastic member 33 is fixedly connected to the first mounting bracket 31 or the second adjustment component 40 respectively. During the implementation of the adjustment of the second-direction movement, the first adjustment member can pass through the second adjustment hole 14 on the housing 10 and abut against the second end of the first mounting bracket 31. Under the action of the elastic force of the first elastic member 33, the first adjustment member drives the light source assembly 50 on the angle adjustment component 20 to move along the direction of the first guiding member 32 through the first mounting bracket 31.

[0120] Exemplarily, the first guiding member 32 may include, but is not limited to, a guiding rod, a guiding shaft, etc. The first adjustment member may include, but is not limited to, a pin, a screw rod, etc. The first elastic member 33 may include, but is not limited to, a spring piece, a spring, etc.

In this embodiment, the number of the first guiding members 32 and the channels 312 is both two, and they are separately arranged on both sides of the first mounting bracket 31.

[0122] The first elastic member 33 is fixedly connected to at least one of the first mounting bracket 31 and the second adjustment component 40 to ensure the fixing stability of the first elastic member 33.

One end of the first elastic member 33 is fixedly connected to the first elastic mounting position 417, and the other end abuts against the first spring abutting recess. By setting the first elastic mounting position 417 and the first spring abutting recess, the position of the first elastic member 33 is defined, and the sliding of the first elastic member 33 during the movement adjustment is avoided, further improving the accuracy and reliability of the position adjustment.

[0124] In an alternative embodiment, as Figures 3 - 4As shown, one end of the first elastic member 33 is fixedly connected to the first elastic mounting position 417 of the second adjustment assembly 40, and the other end of the first elastic member 33 abuts against the first spring abutment recess of the first mounting frame 31. Alternatively, one end of the first elastic member 33 is fixedly connected to the first elastic mounting position of the first mounting frame 31, and the other end of the first elastic member 33 abuts against the first spring recess of the second adjustment assembly 40. In other embodiments, both ends of the first elastic member 33 are fixedly connected to the first mounting frame 31 and the second adjustment assembly 40, respectively.

[0128] Specifically, during the movement adjustment along the second direction, the first adjustment member is operated to pass through the second adjustment hole 14 and the first auxiliary through hole 412 and then abut against the clearance portion 313, so that the force acting on the first adjustment member is transmitted to the first mounting frame 31, thereby achieving the movement adjustment of the light source assembly 50 in the second direction.

In this embodiment, the number of both the installation position 522 and the fixing hole 28 is two. The connecting wire on the circuit board 52 passes through the wire connection position 521, can pass through the wire outlet groove 27 on the same side of the angle adjusting assembly 20, and is connected to an external device through the outlet hole 110 on the housing 10, thus ensuring that the connecting wire does not affect the angle adjustment of the emitted light of the light source element 51 and reducing the operation difficulty of light source adjustment.

[0152] In an alternative embodiment, the optical device further includes at least one optical path adjustment element configured to modulate the emitted light of the light source assembly 50.

For example, it may include, but is not limited to, optical lenses, diaphragms, and the like.

[0153] It should be noted that the specific structure of the optical device is not specifically limited here. For the specific details of the position adjustment device, reference can be made to the foregoing embodiments and will not be elaborated herein.

[0154] In the above embodiments, through multiple adjustment components arranged in a nested manner and cooperating with the position adjustment holes on the housing, the rapid adjustment of the light source position of the light source assembly in three dimensions of angle, horizontal, and vertical can be achieved outside the housing, without the need to disassemble the outer shell of the optical instrument to adjust each adjustment member in sequence, simplifying the operation process of position adjustment, improving the operation efficiency, and reducing the adjustment time. In addition, compared with the stacked structure, the adjustment mechanism of the present invention adopts a structure of mutual nesting and wrapping, which is not only more compact in structure, has a high space utilization rate, but also has higher reliability and better stability of the device.

[0155] The above are the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
