Description

Technical Field

[0001] This invention relates to laser emitting components. It also relates to laser emitting devices. Background Technology

[0002] A laser emitter is a device that emits laser light. Utilizing the properties of laser light, it can perform functions such as ranging, detection, warning, and positioning. The laser emitting device is the main component of a laser emitter. Current laser emitting devices generally consist of a module housing and a laser module within the housing. To ensure the accuracy of laser positioning and measurement functions, the coaxiality of the laser module and the housing needs to be adjusted. Higher coaxiality results in higher accuracy of laser measurement.

[0003] Currently, laser emitters on the market typically adjust the coaxiality of the laser module and its sleeve by adjusting screws to push the sidewall of the laser module and utilizing the deformation of the positioning rubber ring at the front end of the laser module, thus ensuring the accuracy of the laser emission angle. This invention provides a laser emitting assembly and device that differs from existing technologies, enabling convenient adjustment of the laser module's position and ensuring precise laser emission angle or position. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a laser emitting assembly with a simple structure. After being installed inside the module sleeve of a laser emitting device, this laser emitting assembly allows for convenient and rapid adjustment of the coaxiality between the laser module and the module sleeve via adjusting elements, ensuring precise laser emission angle or position, thereby improving the accuracy of laser measurement, positioning, and other functions.

[0005] The present invention also provides a laser emitting device with a simple structure, which is very convenient and quick to adjust the coaxiality of the laser emitting module and the module sleeve, so as to make the laser emission angle or position accurate.

[0006] This invention is achieved through the following technical solution:

[0007] A laser emitting assembly includes a laser module. The front end of the laser module has a connector, which includes a front connector and a rear connector. The front connector has an outlet for laser emission. The outer surfaces of both the front and rear connectors are arc-shaped. The front and rear sides of the connector have a front cover and a rear cover. The front cover has an outlet for laser emission and a first connecting surface that is arc-shaped and mates with the front connector. The rear cover has a second connecting surface that is arc-shaped and mates with the rear connector. The front and rear covers are fixedly connected so that the connector is clamped between the first and second connecting surfaces. The connector is clearance-fitted with the first and second connecting surfaces so that the connector can swing between the first and second connecting surfaces when the laser module is radially pushed within the module sleeve of the laser emitter. The outer surfaces of the front and rear connecting parts are densely covered with alternating raised patterns. The first and second connecting surfaces are also densely covered with alternating raised patterns. The raised patterns are dot-shaped or circular lines. Damping oil is filled between the connector and the first and second connecting surfaces.

[0010] A laser emitting device includes a module sleeve and a laser module. The laser module has a connector at its front end, which includes a front connecting part and a rear connecting part. The front connecting part has an outlet for laser emission. The outer surfaces of both the front and rear connecting parts are arc-shaped.

One end of the second elastic element abuts against the rear end cover, and the other end abuts against the laser module.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The outer surfaces of both the front and rear connecting parts of the laser emitting assembly connector of the present invention are arc-shaped, cooperating with the first connecting surface on the front cover and the second connecting surface on the rear cover. Both the first and second connecting surfaces are arc-shaped, clamping the connector head from front to back, forming a stable and micro-movement-allowing "double arc-shaped clamping" structure. When the laser emitting assembly is installed on the module sleeve to form a laser emitting device and the laser emission angle is adjusted, the laser module is pushed by the adjusting element of the laser emitting device, allowing the connector head to move stably between the first and second connecting surfaces, thereby achieving high-precision, stepless micro-adjustment of the laser emission angle. Furthermore, the clamping of the connector head by the first and second connecting surfaces ensures stable and controllable movement of the connector head at the front of the laser module when the laser module is pushed, improving adjustment efficiency.

[0013] 2. The laser emitting device of the present invention has a third connecting surface with an arc shape on the module sleeve. The outer surfaces of the front and rear connecting parts of the connector are both arc-shaped. A front cover is provided on the front side of the connector, and a first connecting surface with an arc shape is provided on the front cover. The first and third connecting surfaces clamp the connector from front to back, forming a stable and micro-movement-allowing "double arc-shaped clamping" structure. When the adjusting element pushes the laser module, the connector can move stably between the first and third connecting surfaces, thereby achieving high-precision, stepless micro-adjustment of the laser emission angle. Furthermore, the clamping of the connector by the first and third connecting surfaces ensures that the connector at the front of the laser module moves stably and within a controllable range when the laser module is pushed, thus improving adjustment efficiency. In another embodiment of the laser emitting device of the present invention, the module sleeve is provided with a fourth connecting surface that is arc-shaped and cooperates with the front connecting part of the connector. The rear connecting part of the connector cooperates with the second connecting surface that is arc-shaped on the rear cover. The module sleeve and the rear cover also clamp the connector in front and behind to form a stable "double arc-shaped clamping" structure that allows for micro-movement, thereby achieving the purpose of conveniently adjusting the position of the laser module.

[0014] 3. The densely distributed raised textures on the front connecting part, rear connecting part, first connecting surface, and second connecting surface of the laser emitting assembly of this invention form a microscopic tooth-like structure. Combined with the damping oil filling the space between the connector and the first and second connecting surfaces, a continuous and uniform damping sensation is generated during adjustment. This allows the operator to clearly perceive the displacement by hand during fine-tuning, effectively preventing large-distance "slippage" or "jumping" of the connector during adjustment, achieving truly stepless precision adjustment and significantly improving adjustment accuracy and user experience. Furthermore, the damping oil has viscosity, which, when filled between the raised textures, forms a microscopic mechanical locking mechanism. When adjustment is complete, the meshing between the raised textures and the viscosity of the damping oil create strong static frictional resistance, effectively resisting accidental displacement of the connector caused by external vibrations and impacts, ensuring the laser module's anti-displacement capability and long-term stability after adjustment. Moreover, the damping oil reduces direct metal wear during relative movement of the raised textures, providing excellent lubrication and extending the service life of key moving parts. Similarly, for laser emitting devices in other embodiments, raised textures are also provided on the connector and the first and third connecting surfaces, as well as on the connector and the second and fourth connecting surfaces, and damping oil is filled in the corresponding contact gaps to achieve the same effect of improving adjustment accuracy, resisting vibration, and reducing wear.

[0015] 4. When the laser emitting device of the present invention adjusts the angle of the laser module by pushing the adjusting element, the connector will swing. The displacement of this swing will inevitably be accompanied by a small axial component. The second elastic element set in the module sleeve can provide axial elastic force during this process. This elastic force, together with the pushing force of the adjusting element, the radial force of the first elastic element and the viscous force of the damping oil, constitutes a dynamic balance system, which ensures that the adjustment action is smooth and unobstructed, making the adjustment process more stable and controllable. It can also effectively buffer the impact and vibration from the outside, ensuring the stable operation of the laser emitting device and strong vibration resistance. Attached Figure Description

[0037] The present invention will now be further described with reference to the accompanying drawings:

[0038] Laser emitting component:

[0039] like Figures 1 to 5 As shown, the laser emitting assembly 10 mainly includes a laser module 2, which generates laser light when powered on. The laser module 2 has a connector 3 at its front end. The laser module 2 includes a sleeve 21 and a laser component 22 disposed within the sleeve 21. The connector 3 is located at the front end of the sleeve 21 and forms an integral structure with the sleeve 21. The connector 3 includes a front connecting portion 31 and a rear connecting portion 32. The center of the front connecting portion 31 has an outlet 301 through which the laser beam passes. Notably, the outer surfaces of both the front connecting portion 31 and the rear connecting portion 32 are constructed as arc surfaces.

[0040] like Figures 1 to 5As shown, the connector 3 has a front cover 41 on its front side. The center of the front cover 41 has an emission hole 401 corresponding to the emission port 301 of the connector 3, through which the laser beam can be emitted sequentially. A first connecting surface 51 with an arc shape is provided on the inner side of the front cover 41. Correspondingly, a rear cover 42 is provided on the rear side of the connector 3, and a second connecting surface 52 with an arc shape is provided on the inner side of the rear cover 42, opposite to the first connecting surface 51. The first connecting surface 51 and the second connecting surface 52 together form a constrained space, within which the connector 3 is clamped. Its front connecting part 31 engages with the first connecting surface 51 of the front cover 41, and its rear connecting part 32 engages with the second connecting surface 52 on the rear cover 42. This double-arc clamping structure allows the connector 3 (along with the entire laser module 2) to make slight relative movements with respect to the first connecting surface 51 and the second connecting surface 52 when subjected to external force, laying the foundation for subsequent laser adjustment. Specifically, when the laser emitting assembly 10 is installed into the laser emitting device (such as... Figure 8 and Figure 9 After the laser module 2 is placed inside module 11, the sidewall of the laser module 2 can be radially pushed by the adjusting element 61, causing the laser module 2 to move. The connector 3 then undergoes a slight deflection (i.e., oscillation) within the constraint space formed by the first connecting surface 51 and the second connecting surface 52, thereby changing the laser emission angle and achieving high-precision, stepless adjustment. Because the connector 3 is clamped by the arc-shaped first connecting surface 51 and the second connecting surface 52, when adjusting the laser by pushing the laser module 2 with the adjusting element 61, the connector 3 (along with the entire laser module 2) can move as a whole smoothly and controllably. Once adjusted, the abutment of the adjusting element 61 and the clamping function of the first connecting surface 51 and the second connecting surface 52 ensure that the position of the laser module 2 remains stable after adjustment, avoiding laser spot drift caused by vibration.

[0041] To achieve smooth swing adjustment while further enhancing the adjustment feel and self-locking stability after adjustment, fine, intermittently spaced ridges (not shown in the figure) are densely arranged on the entire outer surface of the front connecting part 31 and the rear connecting part 32, as well as on the first connecting surface 51 and the second connecting surface 52. These ridges can be uniformly distributed dot-like protrusions or concentric ring-shaped ridges. When the laser module 2 is pushed by the adjusting element 61, the interaction of these ridges prevents the connector 3 from "slipping" or "jumping" over a large distance, ensuring smooth movement of the connector 3 during laser adjustment and guaranteeing adjustment accuracy and efficiency. When adjustment stops, the meshing or interference effect between the ridges generates a certain static friction force, locking the position of the laser module 2. In addition, damping oil can be filled into the mating gap between the connector 3 and the first connecting surface 51 and the second connecting surface 52. The damping oil has high viscosity and can form an oil film between the corresponding ridges, making the laser adjustment feel more uniform, smooth, and textured. At the same time, the meshing of the corresponding convex grooves and the viscosity of the damping oil will generate strong friction, ensuring that the laser module 2, which is adjusted to the correct position, remains stable, thereby giving the laser emitting device high vibration resistance.

[0042] Example 1 of a laser emitting device:

[0043] like Figures 6 to 9As shown, the laser emitting device 100 mainly includes a module sleeve 11 and a laser module 2 disposed within the module sleeve 11. The laser module 2 can generate laser light when powered on. The front end of the laser module 2 has a connector 3. The laser module 2 includes a sleeve 21 and laser components 22 disposed within the sleeve 21. The connector 3 is located at the front end of the sleeve 21 and forms an integral structure with the sleeve 21. The connector 3 includes a front connecting part 31 and a rear connecting part 32, which are integrally formed. The center of the front connecting part 31 has an outlet 301 through which the laser beam passes. Specifically, the outer surfaces of both the front connecting part 31 and the rear connecting part 32 are constructed as arc surfaces. A front cover 41 is provided on the front side of the connector 3. The center of the front cover 41 has an outlet hole 401 corresponding to the outlet hole 301 of the connector 3, through which the laser beam can be emitted sequentially. A first connecting surface 51 with an arc shape is provided on the inner side of the front cover 41. Correspondingly, a rear cover 42 is provided on the rear side of the connector 3. A second connecting surface 52 with an arc shape is provided on the inner side of the rear cover 42, which is opposite to the first connecting surface 51. The front cover 41 and the rear cover 42 are fixedly connected to the module sleeve 11, so that the first connecting surface 51 and the second connecting surface 52 together form a constrained space. The connector 3 is clamped in this space, with its front connecting part 31 cooperating with the first connecting surface 51 of the front cover 41, and its rear connecting part 32 cooperating with the second connecting surface 52 on the rear cover 42. This double arc-shaped clamping structure allows the connector 3 (along with the entire laser module 2) to make slight relative movements relative to the first connecting surface 51 and the second connecting surface 52 when subjected to external force, laying the foundation for subsequent laser adjustment. There are various ways to fix the front cover 41 and the rear cover 42 to the module sleeve 11, such as... Figure 9As shown, the front cover 41 is threaded into the rear cover 42, and then the front cover 41 and the rear cover 42 are connected as a whole to the module sleeve 11 through the external thread on the rear cover 42. Alternatively, the front cover 41 and the rear cover 42 can also be threaded into the module sleeve 11 respectively, forming the aforementioned constraint space after they are connected to the module sleeve 11. A recessed groove 402 can be provided on the end face of the front cover 41 to facilitate connecting it to the rear cover 42 with a tool. Similarly, a similar groove can be provided on the rear cover 42 to facilitate connecting it to the module sleeve 11 with a tool. In this embodiment, the module sleeve 11 is provided with an adjustment element 61 that can radially push the laser module 2 to adjust the position of the laser module 2. By adjusting the element 61, the side wall of the laser module 2 can be pushed, causing the laser module 2 to move. The connector 3 undergoes a slight deflection (i.e., oscillation) within the constraint space formed by the first connecting surface 51 and the second connecting surface 52, thereby changing the laser emission angle and achieving high-precision, stepless adjustment. Because the connector 3 is clamped by the first connecting surface 51 and the second connecting surface 52, which are arc-shaped, the connector 3 (along with the entire laser module 2) can move as a whole smoothly and controllably when the laser is adjusted by pushing the laser module 2 with the adjusting element 61. After adjustment, the position of the laser module 2 is stably maintained by the abutment of the adjusting element 61 and the clamping function of the first connecting surface 51 and the second connecting surface 52, thus avoiding laser spot drift caused by vibration.

[0044] like Figure 8 and Figure 9As shown, in this embodiment, the adjusting element 61 includes an adjusting screw 611 connected to the module sleeve 11 and capable of pushing against the side wall of the laser module 2 when rotated. The adjusting element 61 also includes a first elastic element 612 disposed between the laser module 2 and the module sleeve 11 and capable of deforming in the radial direction when the laser module 2 is pushed. Rotating the adjusting screw 611 allows its front end to push against the side of the laser module 2. When the laser module 2 moves, it will press against the first elastic element 612 and deform. In this embodiment, the first elastic element 612 is an arc-shaped elastic sheet, with its arc apex abutting against the laser module 2 and its two ends abutting against the inner wall of the module sleeve 11. When the adjusting screw 611 is rotated to push against the laser module 2, the laser module 2 will overcome the elastic force of the first elastic element 612, causing the connector 3 to undergo a slight deflection within the constraint space formed by the first connecting surface 51 and the second connecting surface 52, thereby changing the laser emission angle and achieving high-precision, stepless adjustment. After the adjusting screw 611 is loosened, the laser module 2 maintains close contact with the end of the adjusting screw 611 under the rebound force of the first elastic element 612. Combined with the clamping function of the first connecting surface 51 and the second connecting surface 52 on the connector 3, this ensures that the position of the laser module 2 is stably maintained after adjustment, preventing laser spot drift caused by vibration. Of course, the adjusting element 61 can also adopt other adjusting structures. For example, three to four adjusting screws can be arrayed on the outer periphery of the module sleeve 11. This adjusting structure eliminates the need for the first elastic element 612, and the laser module can be pressed together by loosening or tightening each adjusting screw.

[0045] In this embodiment, fine, intermittently spaced ridges (not shown in the figure) are densely arranged on the entire outer surface of the front connecting portion 31 and the rear connecting portion 32, as well as on the first connecting surface 51 and the second connecting surface 52. These ridges can be uniformly distributed dot-like protrusions or concentric ring-shaped ridges. When the laser module 2 is pushed by the adjusting element 61, the interaction of these ridges prevents the connector 3 from "slipping" or "jumping" over a large distance, ensuring smooth movement of the connector 3 during laser adjustment and ensuring adjustment accuracy and efficiency. When adjustment stops, the meshing or interference effect between the ridges generates a certain static friction force, locking the position of the laser module 2. In addition, damping oil can be filled into the mating gap between the connector 3 and the first connecting surface 51 and the second connecting surface 52. The damping oil has high viscosity and can form an oil film between the corresponding ridges, making the laser adjustment feel more uniform, smooth, and textured. Simultaneously, the meshing of the corresponding convex grooves and the viscosity of the damping oil generate strong friction, ensuring that the laser module 2, when properly adjusted, remains stable, thereby giving the laser emitting device high vibration resistance.

[0046] like Figure 8 and Figure 9As shown, a second elastic element 62, such as a compression spring, is added between the tail end of the laser module 2 and the rear end of the module sleeve 11. This second elastic element 62 is axially oriented. The rear end of the module sleeve 11 can be threaded onto a rear end cover 12. One end of the second elastic element 62 abuts against the rear end cover 12, and the other end abuts against the tail end of the laser module 2. Therefore, the second elastic element 62 applies a forward-pushing preload to the laser module 2 axially, ensuring that the connector 3 at the front end of the laser module 2 remains tightly against the first connecting surface 51 of the front cover 41, thus enhancing the stability of the front end fit of the laser module 2. When radial adjustment is performed (i.e., by pushing with adjusting element 61), the laser module 2 deflects, and the second elastic element 62 can also produce slight deformation in the axial direction to adapt to the change in the angle of the laser module 2. Furthermore, the second elastic element 62, the first elastic element 612, and the damping oil work together to balance the connector 3 from all directions, ensuring that the laser adjustment process is more stable and controllable, and also enhancing the vibration resistance of the laser emitting device.

[0047] like Figure 8 and Figure 9 As shown, a separate lens section 8 is also connected to the front end of the module sleeve 11. The lens section 8 mainly includes a lens holder 81 that is detachably (e.g., by thread) connected to the front end of the module sleeve 11. The center of the lens holder 81 is provided with a final laser emission outlet 82, which is aligned with the emission port 301 of the connector 3 and the emission hole 401 of the front cover 41. Inside the lens holder 81, in the optical path between the laser emission outlet 82 and the emission hole 401, a lens 83 is fixedly installed.

[0048] Example 2 of laser emitting device:

[0049] like Figures 10 to 14 As shown, the difference between embodiment 2 and embodiment 1 of the laser emitting device is that the rear cover 42 is omitted in this embodiment. Instead, a third connecting surface 53 is directly provided on the module sleeve 11. The third connecting surface 53 is an arc surface and mates with the rear connecting part 32 of the connector 3. The third connecting surface 53 is also provided with dot-shaped or line-shaped raised textures. When the front cover 41 is connected to the module sleeve 11, the first connecting surface 51 on the front cover 41 and the third connecting surface 53 on the module sleeve 11 together clamp the connector 3, which also constitutes a "double arc surface clamping" structure. The connector 3 is in clearance fit with the first connecting surface 51 and the third connecting surface 53, and the clearance is filled with damping oil. When the laser module 2 is pushed by an external force, the connector 3 swings between the first connecting surface 51 and the third connecting surface 53. When the adjusting element 61 pushes the laser module 2, the laser module 2 deflects, and the connector 3 deflects slightly (i.e. oscillates) within the constraint space formed by the first connecting surface 51 and the third connecting surface 53, thereby changing the laser emission angle and achieving high-precision, stepless adjustment.

[0050] Example 3 of laser emitting device:

[0051] like Figures 15 to 19 As shown, the difference between embodiment 3 and embodiment 1 of the laser emitting device is that the front cover 41 is omitted in this embodiment. Instead, a fourth connecting surface 54 is directly provided at the front end of the module sleeve 11. The fourth connecting surface 54 is an arc surface and cooperates with the front connecting part 31 of the connector 3. The fourth connecting surface 54 is provided with dot-shaped or line-shaped raised textures. When the rear cover 42 is fixedly connected to the module sleeve 11, the fourth connecting surface 54 on the module sleeve 11 and the second connecting surface 52 on the rear cover 42 together clamp the connector 3, which also constitutes a "double arc surface clamping" structure. The connector 3 is in clearance fit with the second connecting surface 52 and the fourth connecting surface 54, and the clearance is filled with damping oil. When the laser module 2 is pushed by an external force, the connector 3 swings between the second connecting surface 52 and the fourth connecting surface 54. When the adjusting element 61 pushes the laser module 2, the laser module 2 deflects, and the connector 3 undergoes a slight deflection (i.e., oscillation) within the constraint space formed by the second connecting surface 52 and the fourth connecting surface 54, thereby changing the laser emission angle and achieving high-precision, stepless adjustment. The second elastic element 62 applies a forward-pushing preload to the laser module 2 in the axial direction, ensuring that the connector 3 at the front end of the laser module 2 is always tightly attached to the fourth connecting surface 54 on the module sleeve 11, enhancing the stability of the front end fit of the laser module 2.

[0052] Figure 20 and Figure 21 A schematic diagram of the laser emitting device 100 and battery assembly 200 assembled together to form a laser emitter is shown. A switch (not shown) is provided on the battery assembly 200. The battery assembly 200 provides operating power to the laser module 2, and the user can control the laser to turn on and off by operating the switch.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
