Description

Technical Field

[0001] This application relates to the field of industrial laser mounting technology, and more particularly to a laser support structure based on microgroove feet. Background Technology

[0002] During the testing of laser output stability, it was found that the laser's pointing stability and power stability fluctuated greatly during the ambient temperature cycle test. The shell would expand or contract due to temperature changes, and the degree of expansion or contraction varied at different locations on the shell. This caused stress concentration in the internal structure and other factors, resulting in torsion in the overall structure.

[0003] The existing installation and fixing structures for femtosecond lasers are relatively simple, with imprecise distribution of installation and fixing positions. They often involve directly creating slots in the housing for rigid fixing or installing an adapter block at the bottom with holes in the adapter block for rigid fixing. These simple installation and fixing structures cannot effectively resist or mitigate deformation caused by the housing itself and the deformation resulting from screw tightening, thus affecting the laser's directivity and power stability, and consequently, its overall performance. Using a complex adjustment system is problematic due to its complex structure, high installation precision requirements, high cost, and increased barrier to entry. Current technologies have the following drawbacks: the simple fixing structure cannot eliminate deformation of the laser housing caused by external factors during use, or deformation caused by screw tightening; the simple connection structure results in poor stability; and complex adjustment systems are cumbersome, have numerous components, high unit processing costs, and are inconvenient for installation and subsequent maintenance.

[0004] Therefore, a support structure is urgently needed to solve at least one of the above problems. Utility Model Content

[0005] This application provides a laser support structure and laser based on microgroove feet, aiming to solve the problem that simple installation and fixing structures cannot effectively resist or release the deformation of the housing itself and the deformation caused by screw fixing, thereby affecting the laser's directivity and power stability, and thus affecting the overall performance of the laser.

[0006] In a first aspect, embodiments of this application provide a laser support structure based on microgroove feet for supporting the housing of a laser; comprising:

[0007] At least one first microgroove foot and at least one second microgroove foot; the first microgroove foot includes a first support block and a first fixing seat, and the second microgroove foot includes a second support block and a second fixing seat; the first fixing seat and the second fixing seat are connected to the side wall of the housing, and the first support block and the second support block are installed at the bottom of the housing;

[0008] Wherein, the unloading direction corresponding to the first microgroove foot is the longitudinal direction perpendicular to the light emission direction corresponding to the shell; the unloading direction corresponding to the second microgroove foot is the transverse direction perpendicular to the light emission direction corresponding to the shell.

[0009] In some embodiments, the limiting surface of the first support block is a semi-cylindrical structure, and the corresponding installation direction is a transverse direction parallel to the light emission direction. The first support block is connected to the bottom mounting surface of the housing by fixing screws, and the mounting surface of the first support block is provided with an inwardly recessed step surface.

[0010] In some embodiments, the limiting surface of the first fixing seat is a V-groove shape structure, which limits and supports the first support block by making line contact with the semi-cylindrical shape structure of the first support block through the V-groove shape structure.

[0011] In some embodiments, the first fixing seat has centrally symmetrical screw mounting slots on both sides of the outer facade and centrally symmetrical screw mounting slots on both sides of the bottom surface. The first fixing seat is connected to the side wall of the housing through the slots on the outer facade and the shoulder screws. The first fixing seat has a first micro-unloading groove distributed vertically between the inner side of the screw mounting slots on the bottom surface and the outer side of the V-shaped groove structure.

[0012] In some embodiments, the direction of the first micro-unloading groove is parallel to the V-shaped groove structure, and an inwardly sinking step surface is provided directly below the V-shaped groove structure.

[0013] In some embodiments, the limiting surface of the second support block is a semi-cylindrical structure, and the corresponding installation direction is a longitudinal direction perpendicular to the light emission direction. The second support block is connected to the bottom mounting surface of the housing by fixing screws, and the mounting surface of the second support block is provided with an inwardly recessed step surface.

[0014] In some embodiments, the limiting surface of the second fixing seat is a V-groove shape structure, which provides limiting support through line contact between the V-groove shape structure and the semi-cylindrical shape structure of the second support block.

[0015] In some embodiments, the second fixing seat has centrally symmetrical screw mounting slots on both sides of the outer facade and centrally symmetrical screw mounting slots on both sides of the bottom surface. The second fixing seat is connected to the side wall of the housing through the slots on the outer facade and the shoulder screws. The second fixing seat has a second micro-unloading groove distributed vertically between the inner side of the screw mounting slots on the bottom surface and the outer side of the V-shaped groove structure.

[0016] In some embodiments, the direction of the second micro-unloading groove is parallel to the V-shaped groove structure, and an inwardly sinking step surface is provided directly below the V-shaped groove structure.

[0017] In some embodiments, the number of the first microgroove feet is greater than the number of the second microgroove feet.

[0018] To address the problems mentioned in the background art, this utility model provides a microgroove foot fixing structure for improving laser performance. The long side of the laser is defined as parallel to the light output direction, referred to as the longitudinal direction, and the wide side of the laser is defined as perpendicular to the light output direction, referred to as the transverse direction. This structure consists of a longitudinal and transverse stress-relief fixing structure, connected to the housing only by a support block. The V-groove fixing seat limits the support block, effectively absorbing housing deformation caused by changes in external factors, further reducing the torsion of the optical mounting plane caused by external factors, releasing linear deformation in the longitudinal and transverse directions, achieving good results in housings of different sizes and models. By using microgroove feet with two different stress-relief directions, the deformation of the housing itself caused by external factors and the tensile stress deformation generated during screw tightening can be effectively released during laser use, thereby improving the laser's light output stability. Compared to complex adjustment structures, the microgroove grounding structure of this invention is easy to install and maintain, requires fewer parts, and has low processing costs. By adjusting the distribution and parameters of the foot structure, it can adapt to lasers of different sizes and weights, making it more economical and efficient.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] During the testing of laser output stability, it was found that the laser's pointing stability and power stability fluctuated greatly during the ambient temperature cycle test. The shell would expand or contract due to temperature changes, and the degree of expansion or contraction varied at different locations on the shell. This caused stress concentration in the internal structure and other factors, resulting in torsion in the overall structure.

[0035] The existing installation and fixing structures for femtosecond lasers are relatively simple, with imprecise distribution of installation and fixing positions. They often involve directly creating slots in the housing for rigid fixing or installing an adapter block at the bottom with holes in the adapter block for rigid fixing. These simple installation and fixing structures cannot effectively resist or mitigate deformation caused by the housing itself and the deformation resulting from screw tightening, thus affecting the laser's directivity and power stability, and consequently, its overall performance. Using a complex adjustment system is problematic due to its complex structure, high installation precision requirements, high cost, and increased barrier to entry. Current technologies have the following drawbacks: the simple fixing structure cannot eliminate deformation of the laser housing caused by external factors during use, or deformation caused by screw tightening; the simple connection structure results in poor stability; and complex adjustment systems are cumbersome, have numerous components, high unit processing costs, and are inconvenient for installation and subsequent maintenance.

[0036] Therefore, a support structure is urgently needed to solve at least one of the above problems.

[0037] To solve the above problem, please refer to Figures 1-6 This application provides a laser support structure based on microgroove feet for supporting a laser housing 10; it includes at least one first microgroove foot 20 and at least one second microgroove foot 30; the first microgroove foot 20 includes a first support block 22 and a first fixing seat 21, and the second microgroove foot 30 includes a second support block 32 and a second fixing seat 31; the first fixing seat and the second fixing seat are connected to the side wall of the housing, and the first support block and the second support block are installed at the bottom of the housing; wherein, the unloading direction corresponding to the first microgroove foot is a longitudinal direction perpendicular to the light emission direction corresponding to the housing; the unloading direction corresponding to the second microgroove foot is a transverse direction perpendicular to the light emission direction corresponding to the housing.

[0038] Specifically, the laser support structure proposed in this application addresses the deformation stress of the housing caused by temperature changes and the pointing / power stability issues resulting from the fixed structure through differentiated microgroove feet. Key technical points include:

[0039] The dual-direction stress relief design utilizes two types of microgroove feet (first microgroove foot and second microgroove foot) to correspond to the longitudinal and transverse stress relief directions perpendicular to the light emission direction, respectively, forming an orthogonal stress relief system. The laser emission direction is taken as the axis (Z-axis), the longitudinal direction is a horizontal direction perpendicular to the Z-axis (e.g., Y-axis), and the transverse direction is another horizontal direction perpendicular to the Z-axis (e.g., X-axis), with the two directions being orthogonal.

[0040] The microgroove foot structure comprises: a first microgroove foot, consisting of a first support block (bottom support) and a first fixed seat (sidewall connection), with stress relief in the longitudinal direction (Y-axis direction). A second microgroove foot, consisting of a second support block (bottom support) and a second fixed seat (sidewall connection), with stress relief in the transverse direction (X-axis direction). The support block and fixed seat achieve stress relief through the "microgroove" structure, allowing for minute expansion / contraction displacement of the shell in the corresponding direction, thus avoiding stress concentration.

[0041] The mounting base is rigidly connected to the side wall of the housing (e.g., fixed with screws), and the support block is in rigid contact with the mounting base surface. However, the microgroove structure retains flexible deformation space in a specific direction to balance the fixing stiffness and stress release requirements.

[0042] The first micro-groove foot (longitudinal stress relief) includes: A first fixed base: mounted on the side wall of the housing, with an elongated micro-groove extending longitudinally (Y-axis), the length of which aligns with the stress relief direction. Screw holes are provided within the micro-groove for connection to the housing side wall via screws. A small gap (0.1-0.3mm) is maintained between the screws and the groove wall to allow for slight longitudinal sliding of the housing. A first support block: mounted on the bottom of the housing, corresponding to the first fixed base, with a flat support surface in contact with the mounting base, providing vertical support. The support block is fixed to the bottom of the housing with screws, or integrated with the first fixed base, ensuring that the support block moves synchronously with the housing during longitudinal displacement.

[0043] The second micro-groove foot (lateral stress relief) includes: a second fixed seat: installed on the other side wall of the housing (orthogonal to the side wall where the first fixed seat is located), with a long strip-shaped micro-groove extending laterally (X-axis), the length of the groove aligned with the stress relief direction. The structural design is similar to the first fixed seat, but the micro-groove direction is changed to lateral, allowing for slight lateral sliding of the housing. A second support block: installed at the bottom of the housing, corresponding to the second fixed seat, with the support surface in contact with the mounting base, providing vertical support and allowing for slight lateral displacement. The micro-groove cross-section is rectangular or arc-shaped, with a depth of 5-10mm and a width designed according to the housing dimensions (e.g., 5-8mm), ensuring sufficient sliding allowance after screw fixing. A single foot can have 1-2 micro-grooves; multiple feet distributed together form multi-point stress relief (e.g., two first micro-groove feet and one second micro-groove foot on each side of the housing).

[0044] The first micro-groove footings are symmetrically arranged along both sides of the shell's longitudinal (Y-axis) sidewalls, with at least one footing, to ensure uniform release of longitudinal stress. The second micro-groove footings are symmetrically arranged along both sides of the shell's transverse (X-axis) sidewalls, with at least one footing, orthogonal to the first footings, forming a two-dimensional stress-relief system. The bottom support blocks are distributed in a one-to-one correspondence with the sidewall fixing seats, forming a three-point or multi-point support structure of "sidewall fixing + bottom support" (e.g., a set of footings is provided at the front and rear ends of the shell).

[0045] The connection steps include: Step 1: Pre-set mounting holes on both side walls of the housing, corresponding to the microgroove positions of the first and second fixing seats. Step 2: Fix the first fixing seat to the longitudinal side wall of the housing with screws, passing the screws through the microgroove, but not tightening them to the limit, leaving a clearance of about 0.1mm. Step 3: Fix the second fixing seat to the transverse side wall of the housing with screws, similarly leaving a transverse clearance. Step 4: Fix the first and second support blocks to the bottom of the housing with screws or adhesive, with the support surface in contact with the mounting base surface (such as an optical platform). Anti-slip pads or fine-tuning mechanisms (not required) can be provided on the bottom of the support blocks.

[0046] The mounting base and support block are made of rigid materials (such as aluminum alloy and stainless steel), while the microgroove area can be locally made of materials with lower elastic modulus (such as titanium alloy) to enhance deformation capacity. High-strength stainless steel screws are selected to prevent corrosion from affecting the sliding performance of the microgroove.

[0047] When the housing expands due to temperature increase or contracts due to temperature decrease, longitudinal deformation is released by the microgroove (Y direction) of the first foot, and lateral deformation is released by the microgroove (X direction) of the second foot, avoiding torsion or bending of the housing due to inconsistent deformation in each direction. The directional sliding characteristics of the microgroove allow the housing to freely expand and contract in the X / Y directions, while restricting rotation around the Z-axis and Z-direction displacement (the light output direction is rigidly fixed), ensuring stable optical path pointing.

[0048] In traditional rigid fixing, the local deformation of the housing caused by the screw tightening force is absorbed by the micro-groove gaps—the screw does not completely restrict the housing's displacement in the X / Y directions, but only provides positioning constraints, preventing the tightening force from being converted into internal stress in the housing. The bottom support block provides rigid support in the vertical direction (Z direction) to ensure that the housing does not sag due to gravity; the side wall fixing seat provides "elastic constraints" in the X / Y directions through micro-grooves, balancing rigid positioning and flexible force relief.

[0049] This invention replaces simple rigid fixing by releasing temperature deformation and locking stress through a microgroove structure, improving directivity and power stability. Compared to complex adjustment systems, it features a simpler structure (only two types of mounting components), lower processing costs, and reduced installation precision requirements (no precision adjustment mechanism needed). The number and layout of the mounting feet can be adjusted according to the housing size, adapting to different laser specifications and offering strong versatility. During later maintenance, individual mounting feet can be independently disassembled and replaced without overall disassembly, improving convenience. Through the above design, this support structure ensures the rigidity of the laser installation while achieving directional release of temperature deformation stress, solving the stability problem caused by environmental changes from a mechanical structural perspective, thus combining practicality and economy.

[0050] In some embodiments, such as Figure 3 As shown, the limiting surface of the first support block 22 is a semi-cylindrical structure, and the corresponding installation direction is a transverse direction parallel to the light emission direction. The first support block 22 is connected to the bottom mounting surface of the housing by fixing screws 40, and the mounting surface of the first support block is provided with an inwardly recessed step surface.

[0051] The limiting surface of the first support block adopts a semi-cylindrical structure, and its geometric axis is parallel to the transverse direction of the light output direction (set as the X-axis). The bottom mounting surface is provided with a settling step surface, which is connected to the bottom of the housing by fixing screws.

[0052] First support block: The main body is a block structure, and the top limiting surface is machined into a semi-cylinder. The axis of the cylinder extends horizontally (one of the horizontal directions perpendicular to the Z-axis of the light output direction). The arc surface of the semi-cylinder faces upward and mates with the limiting structure of the first fixing seat. Settlement step surface: An inwardly recessed step (0.5-2mm deep) is made on the bottom mounting surface of the support block (the surface in contact with the bottom of the housing). The stepped area is used for fixing screws to pass through. The screw holes are located inside the step to avoid the screw heads protruding and affecting the flatness of the support surface.

[0053] Connection method: The support block is connected to the pre-drilled screw holes on the bottom of the housing by 2-4 fixing screws passing through the screw holes on the stepped surface. The screw heads are recessed into the step to ensure that the bottom surface of the support block fits tightly against the bottom of the housing, while the semi-cylindrical limiting surface is exposed on the top to cooperate with the first fixing seat. The semi-cylindrical structure allows the housing to rotate or slide slightly in the longitudinal (Y-axis) direction (because the axis is parallel to the X-axis, and the Y-axis is perpendicular to the X / Z direction), releasing longitudinal thermal deformation stress; the recessed stepped surface avoids local stress concentration when the screws are tightened.

[0054] In some embodiments, the limiting surface of the first fixing seat is a V-groove shape structure, which limits and supports the first support block by making line contact with the semi-cylindrical shape structure of the first support block through the V-groove shape structure.

[0055] The limiting surface of the first fixed seat is a V-shaped groove, which forms a line contact limit with the semi-cylinder of the first support block, thereby achieving directional support and release of degrees of freedom through line contact.

[0056] The first fixed seat has a V-shaped groove on its side wall (longitudinal side wall, corresponding to the Y-axis direction). The groove opening faces upward, and the V-angle is usually 90° or 120°. The axis of the groove is parallel to the axis of the semi-cylinder (lateral X-axis direction). The two inclined surfaces of the V-shaped groove form line contact with the outer circle of the semi-cylinder of the first support block (theoretically, two parallel straight lines in contact), and the contact line extends along the X-axis. The line contact allows the housing to make slight displacement or rotation along the Y-axis direction (perpendicular to the X / Z longitudinal direction), while restricting the lateral displacement in the X-axis direction and the light-emitting axial displacement in the Z-axis direction. The rigid constraint of the V-shaped groove provides lateral (X-axis) constraint, and the line contact between the arc surface of the semi-cylinder and the V-shaped groove reduces friction, allowing longitudinal (Y-axis) deformation to be released freely.

[0057] In some embodiments, such as Figure 3 As shown, the first fixing seat 21 has centrally symmetrical screw mounting slots on both sides of its outer facade and centrally symmetrical screw mounting slots on both sides of its bottom surface. The first fixing seat 21 is connected to the side wall of the housing through the slots on its outer facade and the shoulder screws 50. The first fixing seat has a first micro-unloading groove distributed vertically between the inner side of the screw mounting slots on the bottom surface and the outer side of the V-shaped groove structure.

[0058] The first fixed seat is equipped with symmetrical sinkholes and micro-unloading grooves. The shell sidewall is connected by shoulder screws with clearance, and the unloading grooves release their degrees of freedom.

[0059] Screw mounting recessed slots: Symmetrical elongated slots (extending along the transverse X-axis) are provided on both sides of the outer vertical surface of the mounting base (the surface away from the housing). The length direction of the slots is consistent with the unloading direction, and the diameter of the slots is 0.2-0.5mm larger than the diameter of the shoulder screws. Symmetrical slots (extending along the longitudinal Y-axis) are provided on both sides of the bottom surface for connecting the bottom structure. First micro unloading groove: Between the inner side of the slot on the bottom surface and the outer side of the V-shaped groove, 2-3 narrow grooves (width 0.5-1mm, depth 2-5mm) are opened vertically and horizontally in parallel, with the groove direction parallel to the axis of the V-shaped groove (X-axis direction).

[0060] The shoulder screw passes through the waist hole on the vertical surface and connects to the screw hole on the side wall of the housing. A gap (0.1-0.3mm) is reserved between the screw shoulder and the edge of the waist hole to allow the fixing seat to slide slightly along the X-axis. The stress relief groove weakens the local stiffness of the fixing seat, so that when the lateral (X-axis) deformation occurs, the stress is released through the elastic deformation of the groove, avoiding transmission to the housing.

[0061] In some embodiments, the direction of the first micro-unloading groove is parallel to the V-shaped groove structure, and an inwardly sinking step surface is provided directly below the V-shaped groove structure.

[0062] The first micro-unloading groove is parallel to the V-shaped groove (lateral X-axis), and a settlement step surface is set below the V-shaped groove to enhance the release of lateral stress and positioning accuracy.

[0063] The stress-relieving grooves extend along the X-axis, perfectly parallel to the axis of the V-shaped grooves. There are 2-4 grooves spaced 5-10mm apart, with a depth penetrating 1 / 3-1 / 2 of the mounting base thickness, providing sufficient strength while maintaining flexible deformation capability. The elastic deformation of the grooves absorbs thermal deformation stress. An inwardly recessed step (1-3mm deep) is created on the bottom surface of the mounting base directly below the V-shaped grooves. The step surface contacts the sidewall of the housing, ensuring precise line contact between the V-shaped grooves and the semi-cylinder, preventing the mounting base from tilting due to screw fastening.

[0064] In some embodiments, such as Figure 4 As shown, the limiting surface of the second support block 32 is a semi-cylindrical structure, and the corresponding installation direction is along the longitudinal direction perpendicular to the light emission direction. The second support block 32 is connected to the bottom mounting surface of the housing by fixing screws 40. The mounting surface of the second support block 32 is provided with an inwardly recessed step surface.

[0065] The limiting surface of the second support block is a semi-cylindrical structure with its axis along the longitudinal direction (Y-axis, another horizontal direction perpendicular to the light emission direction). The bottom is provided with a settling step surface, which connects to the bottom of the shell.

[0066] The difference between this second support block and the first support block lies in the direction of the semi-cylindrical axis: the semi-cylindrical axis of the second support block extends along the longitudinal Y-axis (perpendicular to the X / Z axes), with the arc surface of the limiting surface facing upwards, corresponding to the V-groove limiting of the second fixing seat; the bottom settling step surface structure is the same as the first support block, with screw holes located within the step to avoid stress concentration during locking. The semi-cylindrical axis along the Y-axis allows for slight displacement or rotation of the housing in the lateral (X-axis) direction, releasing lateral thermal deformation stress and forming an orthogonal stress-relief system with the X-axis limiting of the first support block.

[0067] In some embodiments, the limiting surface of the second fixing seat is a V-groove shape structure, which provides limiting support through line contact between the V-groove shape structure and the semi-cylindrical shape structure of the second support block.

[0068] The limiting surface of the second fixed seat is a V-shaped groove, which contacts the semi-cylindrical line of the second support block to achieve limiting and release of degrees of freedom.

[0069] The second fixing seat is installed on the transverse side wall of the housing (corresponding to the side wall in the X-axis direction). The axis of the V-shaped groove of the limiting surface extends along the longitudinal Y-axis and is consistent with the semi-cylindrical axis of the second support block. The inclined surfaces on both sides of the V-shaped groove form line contact with the outer circle of the semi-cylindrical circle, and the contact line extends along the Y-axis, allowing the housing to make slight displacement in the X-axis direction (lateral stress relief) and restricting longitudinal displacement in the Y-axis direction and axial displacement in the Z-axis direction. The first fixing seat controls longitudinal (Y-axis) stress relief, and the second fixing seat controls transverse (X-axis) stress relief. The two work together to form a two-dimensional stress release.

[0070] In some embodiments, such as Figure 4 As shown, the second fixing seat 31 has centrally symmetrical screw mounting slots on both sides of the outer facade and centrally symmetrical screw mounting slots on both sides of the bottom surface. The second fixing seat 31 is connected to the side wall of the housing through the slots on the outer facade and the shoulder screws 50. The second fixing seat has a second micro-unloading groove distributed vertically between the inner side of the screw mounting slots on the bottom surface and the outer side of the V-shaped groove structure.

[0071] The second fixed seat is equipped with symmetrical sinkholes and micro-unloading grooves. The shell sidewall is connected by shoulder screws with clearance, and the unloading grooves release their degrees of freedom.

[0072] The outer facade waist hole extends along the longitudinal Y-axis (different from the X-axis direction of the first fixing seat), and the bottom facade waist hole extends along the transverse X-axis; the second micro stress relief groove is located between the inner side of the bottom facade waist hole and the outer side of the V-shaped groove, with the groove direction parallel to the axis of the V-shaped groove (Y-axis direction), and there are 2-3 grooves, with the same size as the stress relief groove in embodiment 3. The shoulder screw passes through the facade waist hole (Y-axis direction), allowing the fixing seat to slide slightly along the Y-axis. The stress relief groove releases the longitudinal (Y-axis) thermal deformation stress through elastic deformation, preventing the shell from twisting due to longitudinal expansion.

[0073] In some embodiments, the direction of the second micro-unloading groove is parallel to the V-shaped groove structure, and an inwardly sinking step surface is provided directly below the V-shaped groove structure.

[0074] The second micro-unloading groove is parallel to the V-shaped groove (longitudinal Y-axis), and a settling step surface is provided below the V-shaped groove to enhance longitudinal stress release and positioning accuracy. Details of the unloading groove and step surface: The unloading groove extends along the Y-axis and is aligned with the axis of the V-shaped groove of the second fixing seat, releasing degrees of freedom and allowing the shell to unload stress through the deformation of the groove during longitudinal expansion and contraction; the settling step surface directly below the V-shaped groove ensures the flatness of the contact surface between the fixing seat and the side wall of the shell, preventing the V-shaped groove from shifting due to screw tightening force and ensuring the line contact accuracy with the semi-cylinder of the second support block.

[0075] In some embodiments, the number of the first microgroove feet is greater than the number of the second microgroove feet.

[0076] By having more first microgroove feet than second microgroove feet, longitudinal stress relief is optimized through an asymmetrical layout (because the laser may be subject to greater temperature deformation in the longitudinal direction).

[0077] Layout design: For example, two first microgroove feet are provided on each side of the longitudinal direction (Y-axis), and one second microgroove foot is provided on each side of the transverse direction (X-axis), forming a "2 to 1" ratio. The first feet are distributed at the front, rear, or middle of the shell, while the second feet are concentrated in the middle or in areas with weaker rigidity. If the laser shell experiences more significant temperature deformation in the longitudinal direction (e.g., the length direction), increasing the number of first feet can provide multi-point longitudinal stress relief, avoiding single-point stress concentration; if the transverse (width direction) deformation is smaller, reducing the number of feet can simplify the structure and reduce costs.

[0078] In some embodiments, the number of first microgroove feet is 2, and the number of second microgroove feet is 1.

[0079] Two first microgroove feet are provided on each of the longitudinal sides of the housing (two in total), located at the bottom of the front and rear ends of the housing respectively, corresponding to the fixing seats on the longitudinal sidewalls; one second microgroove foot is provided on one side of the housing (or 0.5 on each side, actually one symmetrical layout), located at the bottom of the middle part of the housing, corresponding to the fixing seat on the transverse sidewall.

[0080] Two first feet provide longitudinal stress relief at both ends to prevent the housing from bending longitudinally due to temperature changes; one second foot simplifies the lateral structure, reducing the number of parts and installation complexity while meeting the lateral stress relief requirements.

[0081] This invention provides a microgroove foot fixing structure to improve laser performance. The long side of the laser is defined as parallel to the light output direction, referred to as the longitudinal direction, and the wide side of the laser is defined as perpendicular to the light output direction, referred to as the transverse direction. This structure consists of longitudinal and transverse stress-relief fixing structures, connected to the housing only by support blocks. A V-groove fixing seat limits the support blocks, effectively absorbing housing deformation caused by changes in external factors, further reducing torsion of the optical mounting plane due to external factors, releasing linear deformation in the longitudinal and transverse directions, and achieving good results in housings of different sizes and models. By using microgroove feet with two different stress-relief directions, the deformation of the housing itself caused by external factors and the tensile stress deformation generated during screw tightening can be effectively released during laser use, thereby improving the laser's light output stability. Compared to complex adjustment structures, the microgroove grounding structure of this invention is easy to install and maintain, requires fewer parts, and has lower processing costs. By adjusting the distribution and parameters of the foot structure, it can adapt to lasers of different sizes and weights, making it more economical and efficient.

[0082] It should be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. It should be understood that when an element or layer is referred to as “on,” “adjacent to,” “connected to,” or “coupled to” other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as “directly on,” “directly adjacent to,” “directly connected to,” or “directly coupled to” other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are merely used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, without departing from the teachings of this application, the first element, component, area, layer, or portion discussed below may be referred to as a second element, component, area, layer, or portion.

[0083] Spatial relation terms such as “below,” “under,” “below,” “under,” “above,” “above,” etc., are used herein for convenience of description to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms are intended to also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, then the element or feature described as “below,” “under,” or “below” other elements or features will be oriented “above” other elements or features. Therefore, the exemplary terms “below” and “under” can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or otherwise) and the spatial descriptive terms used herein will be interpreted accordingly.

[0084] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. When used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising” and / or “including,” when used in this specification, identify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups. When used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0085] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0086] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
