Description

Technical Field

[0001] This utility model relates to the field of laser measurement and calibration, and specifically to a laser module. Background Technology

[0002] Laser modules are commonly used instruments for measurement and calibration. Current laser modules can only emit laser light within a single wavelength range, meaning they can only emit a laser beam of one color, such as red or green. If the color of the external environment is similar to the laser color emitted by the module, the laser light will be difficult to identify, adversely affecting measurement or calibration. For example, if the laser module can only emit a green laser beam, but surrounding objects are also green, the green laser beam will be very difficult to identify, negatively impacting measurement or calibration.

[0003] Therefore, since existing laser modules can only emit laser beams of one color, their applicable range is relatively small. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing laser modules can only emit laser beams of one color, resulting in a limited range of applications.

[0005] To achieve the above objectives, this utility model provides a laser module, which includes a housing, a first laser generating mechanism, a second laser generating mechanism, a beam combining mechanism, and a light emitting mechanism.

The first laser generating mechanism is configured to emit a first laser beam that can pass through the beam combining mechanism to the light emitting mechanism. The second laser generating mechanism is configured to emit a second laser beam that can be reflected by the beam combining mechanism to the light emitting mechanism. The first laser beam and the second laser beam have different wavelength ranges, and the beam combining mechanism is configured to make the first laser beam and the second laser beam completely overlap between the beam combining mechanism and the light emitting mechanism.

[0008] In some embodiments, the shell wall of the first housing is provided with multiple rows of first screw holes for mounting bolts, the first screw holes communicating with a first mounting channel, and the first laser generating mechanism being bonded to the first mounting channel; and / or, the shell wall of the second housing is provided with multiple rows of second screw holes for mounting bolts, the second screw holes communicating with a second mounting channel, and the second laser generating mechanism being bonded to the second mounting channel.

[0009] In some embodiments, the first laser generating mechanism includes a first laser generator, a first mounting tube, and a first focusing lens assembly. The first mounting tube is mounted in a first mounting channel, the first laser generator is fixedly mounted inside the first mounting tube, the first laser generator is capable of emitting a first laser beam toward the first focusing lens assembly, the first focusing lens assembly is fixedly mounted inside the first mounting tube, the first focusing lens assembly is located between the first laser generator and the light beam combining mechanism, and the first focusing lens assembly is capable of focusing the first laser beam and propagating it in a direction parallel to the axis of the first mounting channel; and / or, the second laser generating mechanism includes a second laser generator, a second mounting tube, and a second focusing lens assembly. The second mounting tube is detachably mounted in a second mounting channel, the second laser generator is fixedly mounted inside the second mounting tube, the second laser generator is capable of emitting a second laser beam toward the second focusing lens assembly, the second focusing lens assembly is fixedly mounted inside the second mounting tube, the second focusing lens assembly is located between the second laser generator and the light beam combining mechanism, and the second focusing lens assembly is capable of focusing the second laser beam and propagating it in a direction parallel to the axis of the second mounting channel.

[0010] In some embodiments, the first focusing lens assembly includes an annular first gasket and two first focusing lenses, the first gasket and the first focusing lenses being fixedly installed inside the first mounting tube, and the first gasket being clamped between the two first focusing lenses; and / or, the second focusing lens assembly includes an annular second gasket and two second focusing lenses, the second gasket and the second focusing lenses being fixedly installed inside the second mounting tube, and the second gasket being clamped between the two second focusing lenses.

[0016] The first laser generating mechanism can emit a first laser beam, and the second laser generating mechanism can emit a second laser beam. Because the first and second laser beams have different wavelength ranges, they are two different colors. When the first laser beam has a better color effect, the first laser generating mechanism emits the first laser beam, which passes through a beam combining mechanism and is then emitted from the light-emitting mechanism. When the second laser beam has a better color effect, the second laser generating mechanism emits the second laser beam, which is reflected by the beam combining mechanism and then emitted from the light-emitting mechanism. When neither the first nor the second laser beam has a good color effect, the first laser generating mechanism emits the first laser beam, which passes through the beam combining mechanism, while the second laser generating mechanism emits the second laser beam. The beam combining mechanism reflects the second laser beam, and the beam combining mechanism causes the first and second laser beams to overlap and be emitted from the light-emitting mechanism. This overlap produces a new color. Therefore, the laser module of this invention can emit laser beams of three colors, expanding its application range. Attached Figure Description

[0032] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. It should be understood that the specific embodiments described herein are intended only to explain this utility model and not to limit it. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this utility model by illustrating examples of it.

[0033] like Figure 1 , Figure 5 and Figure 6As shown, this utility model provides a laser module, which includes a housing 1, a first laser generating mechanism 2, a second laser generating mechanism 3, a beam combining mechanism 4, and a light emitting mechanism 5. The first laser generating mechanism 2, the second laser generating mechanism 3, the beam combining mechanism 4, and the light emitting mechanism 5 are mounted on the housing 1, and the second laser generating mechanism 3 and the beam combining mechanism 4 are disposed between the first laser generating mechanism 2 and the light emitting mechanism 5. The first laser generating mechanism 2 is configured to emit a first laser beam that can pass through the beam combining mechanism 4 to the light emitting mechanism 5. The second laser generating mechanism 3 is configured to emit a second laser beam that can be reflected by the beam combining mechanism 4 to the light emitting mechanism 5. The first laser beam and the second laser beam have different wavelength ranges, and the beam combining mechanism 4 is configured to ensure complete overlap between the beam combining mechanism 4 and the light emitting mechanism 5. The light emitting mechanism 5 is configured to allow the first laser beam and the second laser beam to exit to the outside of the housing 1.

[0034] Specifically, the first laser generating mechanism 2 emits a first laser beam, and the second laser generating mechanism 3 emits a second laser beam. Because the first and second laser beams have different wavelength ranges, they are two different colors. When the first laser beam has a better color effect, the first laser generating mechanism 2 emits the first laser beam, which passes through the light combining mechanism 4 and then exits from the light emitting mechanism 5. When the second laser beam has a better color effect, the second laser generating mechanism 3 emits the second laser beam, which is reflected by the light combining mechanism 4 and then exits from the light emitting mechanism 5. When neither the first nor the second laser beam has a good color effect, the first laser generating mechanism 2 emits the first laser beam, which passes through the light combining mechanism 4. Simultaneously, the second laser generating mechanism 3 emits the second laser beam, which is reflected by the light combining mechanism 4. The light combining mechanism 4 then causes the first and second laser beams to overlap and exit from the light emitting mechanism 5, producing a new color after they overlap. Therefore, the laser module of this invention can emit laser beams of three colors, thus expanding its application range.

[0035] For example, the first laser generating mechanism 2 can emit a green first laser beam, and the second laser generating mechanism 3 can emit a red second laser beam. When the green first laser beam is not obvious in the environment, the second laser generating mechanism 3 can emit a red second laser beam. When the red second laser beam is not obvious in the environment, the first laser generating mechanism 2 can emit a green first laser beam. When both the green first laser beam and the red second laser beam are not obvious in the environment, the first laser generating mechanism 2 can emit a green first laser beam, while the second laser generating mechanism 3 can simultaneously emit a red second laser beam. The beam combining mechanism 4 makes the green first laser beam and the red second laser beam overlap, that is, the two laser beams are combined. After the two laser beams overlap, they will appear yellow and become more obvious.

[0036] In some embodiments, the wavelength range of the first laser beam is 515nm-535nm. In some embodiments, the wavelength range of the second laser beam is 625nm-645nm.

[0037] like Figures 4 to 6 As shown, in some embodiments of this utility model, the interior of the outer casing 1 is provided with a first mounting channel 111, a second mounting channel 121, a third mounting channel 131, and a mounting chamber 141. A first laser generating mechanism 2 is fixedly mounted at the first mounting channel 111, a second laser generating mechanism 3 is fixedly mounted at the second mounting channel 121, and a light emitting mechanism 5 is mounted at the end of the third mounting channel 131 away from the light beam combining mechanism 4. At least a portion of the light beam combining mechanism 4 is located in the mounting chamber 141. The mounting chamber 141 is located between the first mounting channel 111 and the third mounting channel 131. The axes of the first mounting channel 111 and the third mounting channel 131 are parallel and extend in a straight line. The axis of the third mounting channel 131 extends in a straight line and is perpendicular to the axis of the second mounting channel 121. The first mounting channel 111, the second mounting channel 121, and the third mounting channel 131 are respectively connected to the mounting chamber 141.

[0038] Specifically, the first mounting channel 111 facilitates the installation of the first laser generating mechanism 2 and allows it to operate in a relatively enclosed environment. The second mounting channel 121 facilitates the installation of the second laser generating mechanism 3 and allows it to operate in a relatively enclosed environment. When the first and second laser beams are directed towards the mounting chamber 141, the first laser beam is transmitted through the optical beam combining mechanism 4, the second laser beam is reflected by the optical beam combining mechanism 4, and the first and second laser beams overlap and converge in the mounting chamber 141 before being directed towards the third mounting channel 131. Preferably, the first, second, and third mounting channels 111, 121, and 131 are all straight channels. Preferably, the first, second, and third mounting channels 131 are all cylindrical channels.

[0039] like Figures 1 to 6 As shown, in some embodiments of this utility model, the outer shell 1 includes a first shell 11, a second shell 12, a third shell 13, and a fourth shell 14. The first shell 11 has a first mounting channel 111 inside, the second shell 12 has a second mounting channel 121 inside, the third shell 13 has a third mounting channel 131 inside, and the fourth shell 14 has a mounting chamber 141 inside. The first shell 11, the second shell 12, and the third shell 13 are respectively connected to the fourth shell 14.

[0040] Specifically, along the axial direction of the first mounting channel 111 or the third mounting channel 131, the first housing 11 and the third housing 13 are respectively mounted on both sides of the fourth housing 14. Preferably, the first housing 11, the second housing 12, and the third housing 13 are cuboid or cylindrical, etc. Preferably, the first housing 11, the second housing 12, the third housing 13, and the fourth housing 14 are integrally formed. Preferably, the outer shell 1 is T-shaped overall, reducing material usage and lowering costs.

[0041] In other embodiments, the outer shell 1 can also be any other structural form that meets the usage requirements of this utility model. For example, the outer shell 1 can be cuboid in shape, with the first mounting channel 111, the second mounting channel 121, and the third mounting channel 131 respectively disposed on the left side, the top side, and the right side, and the mounting chamber 141 disposed in the middle.

[0042] like Figures 2 to 3 As shown, in some embodiments of this utility model, the shell wall of the first housing 11 is provided with multiple rows of first screw holes 112 for mounting bolts. The first screw holes 112 are connected to the first mounting channel 111, and the first laser generating mechanism 2 is bonded to the first mounting channel 111.

[0043] Specifically, due to manufacturing tolerances and other reasons, the first laser generating mechanism 2 may deviate from its preset position, causing the first laser beam to potentially fail to propagate along the preset path. Therefore, it is necessary to calibrate the position of the first laser generating mechanism 2 during installation. Typically, a cross-section is taken perpendicular to the axis of the first mounting channel 111. The minimum cross-sectional dimension of the first mounting channel 111 is larger than the maximum cross-sectional dimension of the first laser generating mechanism 2 to facilitate installation and calibration. After installing the first laser generating mechanism 2 into the first mounting channel 111, bolts are installed in the first screw holes 112, pressing the bolts against the first laser generating mechanism 2. The bolts are then adjusted to change their length extending into the first mounting channel 111 until the first laser beam can propagate along the preset path. Adhesive is then injected into the first mounting channel 111 to bond the first laser generating mechanism 2 to the channel. After the adhesive solidifies, the bolts can be removed.

[0044] like Figures 2 to 3 As shown, in some embodiments of this utility model, the shell wall of the second housing 12 is provided with multiple rows of second screw holes 122 for mounting bolts. The second screw holes 122 are connected to the second mounting channel 121, and the second laser generating mechanism 3 is bonded to the second mounting channel 121.

[0045] Specifically, due to manufacturing tolerances and other reasons, the second laser generating mechanism 3 may deviate from its preset position, causing the second laser beam to potentially fail to propagate along the preset path. Therefore, it is necessary to calibrate the position of the second laser generating mechanism 3 during installation. Typically, a cross-section is taken perpendicular to the axis of the second mounting channel 121. The minimum cross-sectional dimension of the second mounting channel 121 is larger than the maximum cross-sectional dimension of the second laser generating mechanism 3 to facilitate installation and calibration. After installing the second laser generating mechanism 3 into the second mounting channel 121, bolts are installed in the second screw holes 122, pressing the bolts against the second laser generating mechanism 3. The bolts are then adjusted to change their length extending into the second mounting channel 121 until the second laser beam can propagate along the preset path. Adhesive is then injected into the second mounting channel 121 to bond the second laser generating mechanism 3 to the channel. After the adhesive solidifies, the bolts can be removed.

[0046] like Figures 5 to 7As shown, in some embodiments of this utility model, the first laser generating mechanism 2 includes a first laser generator 21, a first mounting tube 22, and a first focusing lens assembly 23. The first mounting tube 22 is mounted in the first mounting channel 111. The first laser generator 21 is fixedly mounted inside the first mounting tube 22. The first laser generator 21 can emit a first laser beam to the first focusing lens assembly 23. The first focusing lens assembly 23 is fixedly mounted inside the first mounting tube 22. The first focusing lens assembly 23 is located between the first laser generator 21 and the light beam combining mechanism 4. The first focusing lens assembly 23 can focus the first laser beam and propagate it along a direction parallel to the axis of the first mounting channel 111.

[0047] Specifically, the first laser generator 21 can emit a first laser beam, and the first focusing lens assembly 23 can focus the first laser beam and make it propagate along a preset path.

[0048] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments of this utility model, the second laser generating mechanism 3 includes a second laser generator 31, a second mounting tube 32, and a second focusing lens assembly 33. The second mounting tube 32 is detachably mounted in the second mounting channel 121. The second laser generator 31 is fixedly mounted inside the second mounting tube 32. The second laser generator 31 can emit a second laser beam to the second focusing lens assembly 33. The second focusing lens assembly 33 is fixedly mounted inside the second mounting tube 32. The second focusing lens assembly 33 is located between the second laser generator 31 and the light beam combining mechanism 4, and the second focusing lens assembly 33 can focus the second laser beam and propagate it along a direction parallel to the axis of the second mounting channel 121.

[0049] Specifically, the second laser generator 31 can emit a second laser beam, and the second focusing lens assembly 33 can focus the second laser beam and make it propagate along two preset paths.

[0050] Of course, the first laser generating mechanism 2 and the second laser generating mechanism 3 can also adopt any other structural form that meets the requirements of this utility model, and this utility model is not limited to this. For example, they can adopt the structural form of the laser generating mechanism in publication number CN119620421A or the structural form of the laser generating mechanism in announcement number CN112186476B. In addition, the first laser generator 21 and the second laser generator 31 are common components in the art. For example, the first laser generator 21 and the second laser generator 31 usually include a PCB control board, a control switch, and a light-emitting component. This utility model will not elaborate on their structure and principle. Of course, the first laser generator 21 and the second laser generator 31 can be powered by their own batteries or by an external power source.

[0051] like Figure 7 As shown, in some embodiments of the present invention, the first focusing lens assembly 23 includes an annular first gasket 231 and two first focusing lenses 232. The first gasket 231 and the first focusing lenses 232 are fixedly installed inside the first mounting tube 22, and the first gasket 231 is clamped between the two first focusing lenses 232.

[0052] Specifically, the first gasket 231 separates the two first focusing lenses 232 to allow the first focusing lenses 232 to function better. Preferably, the axis of the first gasket 231 coincides with the axis of the first mounting tube 22.

[0053] like Figure 8 As shown, in some embodiments of the present invention, the second focusing lens assembly 33 includes an annular second gasket 331 and two second focusing lenses 332. The second gasket 331 and the second focusing lenses 332 are fixedly installed inside the second mounting tube 32, and the second gasket 331 is clamped between the two second focusing lenses 332.

[0054] Specifically, the second gasket 331 separates the two second focusing lenses 332 to allow the second focusing lenses 332 to function better. Preferably, the axis of the second gasket 331 coincides with the axis of the second mounting tube 32.

[0055] Furthermore, the first focusing lens assembly 23 and the second focusing lens assembly 33 can also have other structural forms, and this utility model does not impose any limitations. For example, the first focusing lens assembly 23 and the second focusing lens assembly 33 can each include three or more lenses capable of focusing light.

[0056] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the light beam combining mechanism 4 includes a dichroic mirror 41. The dichroic mirror 41 has a first lens surface 411 and a second lens surface 412 that are relatively distributed in its thickness direction. The dichroic mirror 41 is inclined, and the first laser generating mechanism 2 faces the first lens surface 411, while the second laser generating mechanism 3 and the light emitting mechanism 5 face the second lens surface 412 respectively.

[0057] Specifically, at least a portion of the dichroic mirror 41 is located in the mounting chamber 141. The dichroic mirror 41 allows the first laser beam to pass through and reflects the second laser beam, and also enables the first laser beam to coincide with the second laser beam. For example, the first laser beam can be transmitted from the first lens surface 411 to the second lens surface 412, the second laser beam can be reflected by the second lens surface 412, and the first and second laser beams coincide at the second lens surface 412. Of course, the dichroic mirror 41 is a common optical lens in the art, and its operating principle will not be described in detail in this invention.

[0058] In addition, the optical beam combining mechanism 4 can also be other structural forms, which are not limited by this utility model. For example, the optical beam combining mechanism 4 can be a lens array, a polarizing beam splitter, a beam combiner, or a beam combining prism group, etc.

[0059] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the dichroic mirror 41 is detachably installed in the housing 1 to facilitate the installation and removal of the dichroic mirror 41.

[0060] In some embodiments, the dichroic mirror 41 is provided with an inclined edge. For example, the inclined angle can be any angle that can meet the usage requirements of this utility model, such as 45 degrees, 50 degrees or 60 degrees.

[0061] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the outer shell 1 is provided with a mounting port 15, which communicates with the interior of the outer shell 1. The dichroic mirror 41 is detachably snapped into the mounting port 15, and a portion of the dichroic mirror 41 is located inside the outer shell 1.

[0062] Specifically, when the dichroic mirror 41 needs to be installed, it is inserted into the mounting port 15 and pushed into the mounting chamber 141 until it presses against the chamber wall. At this point, the dichroic mirror 41 is engaged in the mounting port 15. When the dichroic mirror 41 needs to be removed, it is simply pulled out of the mounting port 15. Preferably, the mounting port 15 extends obliquely from the side of the outer casing 1 (e.g., the fourth housing 14) away from the second mounting channel 121 towards the side facing the second mounting channel 121. Preferably, in a direction perpendicular to the plane of the paper, the mounting port 15 penetrates the outer casing 1 (e.g., the fourth housing 14).

[0063] like Figure 5 , Figure 6 and Figure 9As shown, in some embodiments of this utility model, the light-emitting mechanism 5 includes a conical conical reflector 51 and a cylindrical light-transmitting tube 52. One end of the light-transmitting tube 52 is installed on the outer shell 1, and the conical reflector 51 is installed on the other end of the light-transmitting tube 52. The conical reflective surface 511 of the conical reflector 51 faces the light-combining mechanism 4, and the light-transmitting tube 52 surrounds the conical reflective surface 511 of the conical reflector 51.

[0064] Specifically, the conical reflector 51 has a conical reflecting surface 511, which can reflect the first laser beam and the second laser beam, so that the first laser beam and the second laser beam are emitted from the light-transmitting tube 52 and can illuminate surrounding solid objects, such as the surrounding walls. Preferably, the first laser beam and the second laser beam can propagate along the axis of the conical reflector 51.

[0065] In addition, the light-emitting mechanism 5 can be any other structural form that meets the requirements of this utility model, and this utility model does not impose any limitations. For example, the light-emitting mechanism 5 can be a light-transmitting plane mirror, a lens group composed of multiple lenses, or a plate with a light-transmitting hole, etc.

[0066] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of this utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
