[0002] Currently, line laser modules are typically configured to be directly and vertically mounted on circuit boards, which suffers from the technical drawback of limited mounting angles. To address this issue, Chinese patent application "A Detection Module, a Multifunctional Module, and a Mobile Robot" (application number 202111148818.4) discloses a line laser detection module where a line laser sensor is mounted on a housing limiting mechanism, and the housing is fixed to the circuit board with screws. While this solution resolves the limited mounting angle issue on the circuit board, its screw-based assembly method suffers from unstable screw tightness and inflexible mounting angles, leading to inaccurate installation angles and poor installation stability. Utility Model Content

[0003] This application provides a line laser module mounting structure, the specific technical solution of which is as follows:

[0004] The line laser module mounting structure includes a circuit board, a mounting base, and a line laser module. The circuit board has a slot for assembling the mounting base. The mounting base has a limiting hollow structure for assembling the line laser module. The line laser module is snapped onto the limiting hollow structure of the mounting base. The limiting hollow structure engages with the slot on the circuit board, allowing the mounting base and circuit board to assemble. The line laser module forms an angle with the circuit board based on the limiting effect of the limiting hollow structure of the mounting base.

[0005] Furthermore, screw holes are provided on the mounting base and the circuit board respectively. The mounting base is fixed to the circuit board based on screw assembly, and the limiting hollow structure of the mounting base fits into the slot of the circuit board.

[0006] Furthermore, based on the number of line laser lamp units included in the line laser module, the mounting base is set as several separate mounting components equal to the number of line laser lamp units, and the circuit board is correspondingly set with several slots equal to the number of mounting components; each mounting component is provided with a limiting hollow structure for assembling a line laser lamp unit, and each mounting component is correspondingly assembled on the slot of the circuit board, so that each line laser lamp unit forms an angle with the circuit board.

[0007] Furthermore, each mounting component has at least two screw holes, and each slot on the circuit board has a corresponding number of screw holes at the assembly position, so that each mounting component can be assembled onto the circuit board by screws.

[0008] Furthermore, each mounting component is snapped into a corresponding slot on the circuit board, and the mounting component is glued and fixed to the circuit board.

[0009] Furthermore, the limiting hollow structure for the assembly line laser module is provided with a baffle. The baffle is tilted based on the tilt angle formed between the line laser module and the circuit board target, so that the line laser module installed in the limiting hollow structure is constrained by the baffle and forms an tilt angle with the circuit board.

[0010] Furthermore, the circuit board has limiting protrusions on both sides of the slot to limit the position of the mounting components assembled on the slot.

[0011] This application also discloses a line laser module welding and mounting structure, including: a circuit board and a line laser module; wherein, the circuit board is provided with a slot for assembling the line laser module, and the line laser module is fixedly and tiltedly assembled on the slot of the circuit board by half-point welding, forming an angle with the circuit board.

[0012] Furthermore, in the line laser module welding and mounting structure, the slot on the circuit board is provided with limiting protrusions on both sides to limit the position of the line laser module assembled on the slot.

[0014] The line laser module mounting structure described in this application utilizes slots on a circuit board to securely mount the mounting base onto the circuit board.

[0020] The embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described below are for illustrative purposes only and are not intended to limit the scope of this application.

[0021] Currently, line laser modules are typically configured to be directly and vertically mounted on circuit boards, which suffers from the technical drawback of limited mounting angles. To address the issues raised in the Chinese patent application "A Detection Module, Multifunctional Module, and Mobile Robot" (application number "202111148818.4"), which uses a screw-fixed assembly method, problems arise such as unstable screw tightness and inflexible mounting angles, leading to inaccurate installation angles and poor installation stability of the line laser module.

[0022] This application provides a line laser module mounting structure, aiming to optimize the accuracy and stability of the tilt angle formed between the line laser module and the circuit board after installation, while limiting the assembly angle of the line laser module. Specifically, as shown... Figure 1 As shown, the line laser module mounting structure includes: a circuit board 1, a mounting base 2, and a line laser module 3; wherein, the circuit board 1 is provided with a slot 11 for assembling the mounting base; the mounting base 2 is provided with a limiting hollow structure 21 for assembling the line laser module; the line laser module 3 is assembled onto the limiting hollow structure 21 of the mounting base by snap-fit; the limiting hollow structure 21 of the mounting base 2 and the slot 11 of the circuit board 1 are engaged, so that the mounting base 2 and the circuit board 1 are assembled, and the line laser module 3 forms an angle with the circuit board 1 based on the limiting effect of the limiting hollow structure 21 of the mounting base 2.

[0023] Specifically, the mounting base 2 serves as an intermediate medium for assembling the line laser module 3 and the circuit board 1, enabling the line laser module 3 to be stably mounted on the circuit board 1. Furthermore, the limiting hollow structure 21 ensures that the line laser module 3 can be installed at an angle to the circuit board 1. In existing technologies, screws are directly used to assemble the mounting base onto the circuit board. The tightness of the screws affects the assembly of the mounting base on the circuit board, thus affecting the angle between the line laser module and the circuit board. Compared to existing technologies, this application provides a slot 11 on the circuit board 1 for assembling the mounting base 2. The slot 11 securely engages the mounting base 2 onto the circuit board 1, limiting the mounting of the mounting base 2. The limiting hollow structure 21 of the mounting base 2 fits into the slot 11 of the circuit board 1, eliminating the influence of screw assembly on the angle between the line laser module and the circuit board, ensuring a stable angle between them, effectively improving the assembly accuracy of the line laser module, and reducing the installation difficulty of the line laser module based on the slot.

[0024] As a preferred embodiment of this application, such as Figure 1 As shown, the mounting base 2 and the circuit board 1 are respectively provided with screw holes 22 and 12. The mounting base 2 is fixed to the circuit board 1 by screw assembly, and the limiting hollow structure 21 of the mounting base 2 is engaged with the slot 11 of the circuit board 1. Specifically, by providing screw holes on the mounting base and the circuit board respectively, when the mounting base is clamped onto the slot of the circuit board, the two can be connected by screws through the screw holes of both, further optimizing the assembly stability of the mounting base and the circuit board. Moreover, based on the engagement of the circuit board slot and the limiting hollow structure of the mounting base, the effect of the screw tightening degree in the screw hole on the accuracy of the tilt angle formed by the line laser module and the circuit board is eliminated. The tilt angle formed by the line laser module and the circuit board is precisely limited by the limiting hollow structure of the mounting base, ensuring the accuracy and stability of the assembly angle of the line laser module.

[0025] Line laser modules typically include various types such as single-line lasers, dual-line lasers, and multi-line lasers in practical applications. Based on different application requirements, the tilt angle between different line laser lamp units and the circuit board within the same line laser module may have different requirements. As a preferred embodiment of this application, to address the different tilt angle requirements between different line laser lamp units and the circuit board within the same line laser module, such as... Figure 2As shown, based on the number of line laser lamp units included in the line laser module 3, the mounting base 2 is configured as two separate mounting components equal to the number of line laser lamp units. The circuit board has a number of slots equal to the number of mounting components. Each mounting component has a limiting hollow structure for assembling one line laser lamp unit. Each mounting component is fitted onto a slot on the circuit board, causing each line laser lamp unit to form an angle with the circuit board. Although this embodiment uses an appendix... Figure 2 This is an illustration of a dual-line laser module, but the actual protection should include various types of line laser modules such as single-line, dual-line, and multi-line lasers. The number of mounting components is adjusted based on the number of line laser lamp units. This embodiment assembles each line laser lamp unit independently onto a corresponding mounting component. This allows the line laser module to be configured with mounting components that provide different tilt angle limiting functions according to the tilt angle requirements between different line laser lamp units and the circuit board. The mounting component adjusts its tilt angle limiting function based on its hollow limiting structure.

[0026] As a preferred embodiment of this application, such as Figure 1 and Figure 2 As shown, to ensure the stable installation of the mounting components on the circuit board, each mounting component is provided with at least two screw holes. Simultaneously, a corresponding number of screw holes are provided at each corresponding assembly position in each slot on the circuit board, allowing each mounting component to be assembled onto the circuit board using screws, thus improving the mounting performance. The "corresponding assembly position in the slot" refers to the assembly position where the screw holes of the mounting component and the corresponding screw holes on the circuit board are aligned after the limiting hollow component of the mounting component is engaged with the slot on the circuit board. Screw holes are provided at this corresponding assembly position so that the screw holes of the mounting component and the screw holes on the circuit board can align and match, allowing screws to connect the screw holes of the mounting component and the screw holes on the circuit board.

[0027] In a preferred embodiment of this application, each mounting component is snapped into a corresponding slot on the circuit board, and the mounting component is bonded and fixed to the circuit board using adhesive. This embodiment solves the technical defect that the tightening degree during screw assembly affects the tilt angle between the line laser module and the circuit board by using adhesive to firmly bond the mounting components to the circuit board. Adhesive assembly can stabilize the assembly while saving the number of components required for assembly, thus reducing the installation cost of the line laser module.

[0028] In a preferred embodiment of this application, the limiting hollow structure for the assembly line laser module is provided with a baffle. The baffle is tilted based on the angle formed between the line laser module and the circuit board target, so that the line laser module, when installed in the limiting hollow structure, is constrained by the baffle and forms an angle with the circuit board. Figure 1 and Figure 2 The limiting hollow structure 21 shown has a baffle that adjusts the height of each surface of the baffle based on the tilt angle formed between the line laser module and the target circuit board. Based on the height difference, it achieves tilt limitation of the line laser module. Thus, when the mounting base is assembled on the slot of the circuit board, the line laser module is limited by the limiting effect of the external baffle of the limiting hollow structure, so that the line laser module and the circuit board form a tilt angle. Furthermore, the tilt angle between the line laser module and the circuit board can be flexibly adjusted based on the height of each surface of the baffle, optimizing the assembly flexibility of the line laser module and enriching the tilt angle between the line laser module and the circuit board.

[0029] As a preferred embodiment of this application, such as Figure 3 As shown in -a, the slot 11 on the circuit board 1 has limiting protrusions 13 on both sides to limit the positioning of the mounting component 2 assembled on the slot. Figure 3 As shown in -b, the limiting protrusion structure allows the mounting component to be limited when assembled onto the circuit board, enabling the mounting component to be assembled at the specified position more accurately. This reduces the impact of the slot fitting assembly on the tilt angle formed between the line laser module assembly and the circuit board, ensuring the assembly effect of the line laser module.

[0030] As a preferred embodiment of this application, a line laser module welding and mounting structure is provided, which, compared to the line laser module mounting structures of the aforementioned embodiments, is as follows: Figure 4 As shown, the line laser module welding and mounting structure includes: a circuit board 1 and a line laser module 3; wherein, the circuit board 1 is provided with a slot 11 for assembling the line laser module, and the line laser module 3 is fixedly and tiltedly assembled onto the slot 11 of the circuit board 1 by a half-point welding method, forming an angle with the circuit board 1. Figure 4 There are solder joints 14 between the circuit board and the line laser module. Specifically, the line laser module welding and mounting structure provided in this application does not require an additional mounting base for the line laser module assembly. Instead, the line laser module 3 is directly fixed in the slot of the circuit board 1 by half-point welding. Based on the slot limiting the installation position of the line laser module, the welding method ensures the stability of the tilt angle formed between the line laser module and the circuit board, thereby reducing the component cost required for the line laser module mounting structure.

[0031] In a preferred embodiment of this application, the line laser module welding and mounting structure includes limiting protrusions on both sides of the slot on the circuit board to limit the position of the line laser module assembled on the slot. This embodiment, by providing limiting protrusions on the slot of the circuit board, assists in directly snapping the line laser module onto the slot based on the limiting protrusions during assembly line installation. The snapping position between the limiting protrusions and the line laser module serves as a welding reference point, assisting the assembly line in more accurately fixing the line laser module.

[0032] As a preferred embodiment of this application, a line laser system is provided, including a line laser module mounting structure as described in any of the preceding embodiments, or a line laser module welding mounting structure as described in any of the preceding embodiments. By employing the line laser module mounting structure of this application, the line laser system expands the tilt angles that can be formed between the line laser module and the circuit board, ensuring the stability and precision of the line laser module mounting.
