Description

Technical Field

[0001] This application belongs to the field of scanning technology, and in particular relates to a laser scanner. Background Technology

[0002] In related technologies, existing laser scanners typically have complex internal structures, numerous parts, and cumbersome assembly and disassembly procedures. For certain special applications, such as public security departments using laser scanners in criminal injury examinations to provide evidence for subsequent injury assessment and case reasoning, public security departments usually purchase multiple devices. If one device malfunctions during use, due to the confidentiality requirements of the data contained within, the faulty device cannot be returned for repair. Users typically use parts from other working devices for maintenance and replacement, or they troubleshoot the faulty device themselves.

[0003] However, existing laser scanners, due to their fragmented structure, make disassembly and reassembly extremely cumbersome and complex. Furthermore, because each functional component must be individually installed and tested inside the casing, if a faulty or incompatible component is discovered during testing, the casing must be disassembled for readjustment or replacement, making independent maintenance and replacement extremely difficult. In addition, existing scanners, due to their unreasonable structural design, are large and heavy, resulting in poor portability. Utility Model Content

[0037] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0038] This application discloses a laser scanner 100.

[0039] The following is for reference. Figures 1-8 A laser scanner 100 according to an embodiment of this application is described.

[0040] In some embodiments, such as Figures 1-3 As shown, the laser scanner 100 includes: a housing 110, a pre-installed module 120, and an interaction component 130.

[0041] The housing 110 includes a first cover 111, a side frame 112, and a second cover 113 connected in sequence. A pre-installed module 120 is disposed inside the housing 110 and includes an adapter bracket 121, an image acquisition component 122, a laser emitting device 123, and a main control component 124. The adapter bracket 121 is installed on the first cover 111, the image acquisition component 122 and the laser emitting device 123 are installed on the adapter bracket 121, and the image acquisition component 122 and the laser emitting device 123 are electrically connected to the main control component 124. The main control component 124 is positioned and engaged with the adapter bracket 121, and the main control component 124 is connected to the side frame 112. An interaction component 130 is installed on the second cover 113 and is electrically connected to the main control component 124.

[0042] The housing 110 serves as the external protection and mounting carrier for the scanner and can be assembled from the first cover 111, the side frame 112, and the second cover 113 through threaded connections, snap-fit ​​connections, or a combination of these methods.

[0043] In this embodiment, such as Figures 1-3 As shown, the first cover 111 and the second cover 113 can be a cover-like structure with one side open, and the side frame 112 can be a frame-like structure with both sides open. The openings of the first cover 111 and the second cover 113 are respectively connected to the two opposite openings of the side frame 112, so that the first cover 111, the side frame 112 and the second cover 113 together define a relatively closed internal space after assembly.

[0044] The image acquisition component 122 can be used to acquire image information of the object to be measured. The image acquisition component 122 may include, but is not limited to, camera devices such as black and white cameras or color cameras 1223. This application embodiment does not limit this.

[0045] The laser emitting device 123 can be used to emit a laser beam of a specific wavelength and mode toward the object under test, providing a basic signal for subsequent scanning, measurement or imaging processes. The laser emitting device 123 may include, but is not limited to, a line laser emitter or a point laser emitter, etc., and the embodiments of this application do not limit this.

[0046] The interactive component 130 can be used to provide users with command input and status display. The interactive component 130 may include, but is not limited to, touch screen, display screen and operation buttons, etc., and the embodiments of this application do not limit it.

[0047] As an example, such as Figure 2 As shown, the interactive component 130 may include a touchscreen. Users can directly view scanning data, device status, and other information through the touchscreen, and can also perform operations such as powering on / off, starting scanning, and setting parameters by touching the touchscreen.

[0048] The main control component 124 may include, but is not limited to, the PCB board 1241 (Printed Circuit Board) and electronic components such as processors, memory and power management on it, and the embodiments of this application do not limit this.

[0049] The image acquisition component 122 and the laser emitting device 123 can be installed on the adapter bracket 121 by means of threaded connection, snap-fit ​​or hybrid connection, and this application embodiment does not limit this.

[0050] As an example, the adapter bracket 121 may be provided with a stud structure with external threads, and the image acquisition component 122 may be provided with a threaded hole structure for engaging with the external threads of the stud structure.

[0051] As an example, a receiving groove for accommodating a laser emitting device 123 can be formed on the adapter bracket 121. A through threaded hole can be provided on the side wall of the receiving groove. After the threaded connector 150 is screwed into the threaded hole, the threaded connector 150 abuts against the side wall of the laser emitting device 123, thereby pressing the laser emitting device into the receiving groove.

[0052] The adapter bracket 121 can be installed on the first cover 111 by means of threaded connection, snap-fit ​​or hybrid connection, and this application embodiment does not limit this.

[0053] As an example, both the adapter bracket 121 and the first cover 111 can be provided with threaded holes. A threaded connector 150 is used to symmetrically connect and secure the threaded holes of the adapter bracket 121 and the first cover 111. To further improve positioning accuracy, auxiliary positioning can also be achieved between the adapter bracket 121 and the first cover 111 using methods such as positioning pin 1211-positioning hole fit, positioning protrusion-positioning groove 1101 fit, magnetic fit, guide rail-slide groove fit, or a combination of these methods.

[0054] The image acquisition component 122, the laser emitting device 123, and the main control component 124 can be electrically connected to the main control component 124 via cables or flexible circuit boards, etc., and this application embodiment does not limit this.

[0055] The positioning and engagement between the main control component 124 and the adapter bracket 121 can be achieved through positioning post 1211-positioning hole engagement, positioning protrusion-positioning groove 1101 engagement, magnetic engagement, guide rail-slide groove engagement, or a combination of these methods. This application embodiment does not limit this.

[0056] The main control component 124 can be installed on the adapter bracket 121 by means of threaded connection, snap-fit ​​or hybrid connection, and this application embodiment does not limit this.

[0057] In actual implementation, such as Figures 1-3As shown, the assembly of the laser scanner 100 can be achieved through the following steps: the image acquisition component 122 and the laser emitting device 123 are pre-installed on the adapter bracket 121, and the electrical control component is simply positioned and matched with the adapter bracket 121. After completing the electrical connection between the image acquisition component 122, the laser emitting device 123 and the main control component 124, the image acquisition component 122, the laser emitting device 123, the electrical control component and the adapter bracket 121 together form a pre-assembled module 120 that can be independently debugged. The adapter bracket 121 is installed and fixed to the first cover 111 to achieve initial fixation of the pre-installed module 120; the assembly consisting of the pre-installed module 120 and the first cover 111 is assembled with the side frame 112 so that the main control component 124 is fixedly connected to the side frame 112, thereby achieving further positioning and reinforcement of the pre-installed module 120; finally, the second cover 113, on which the interaction component 130 has been installed, is connected to the side frame 112 to complete the assembly of the housing 110, forming an internal space that can stably accommodate and protect the pre-installed module 120.

[0058] It should be noted that before the image acquisition component 122, the laser emitting device 123 and the main control component 124 are pushed into the side frame 112, all related cables and ribbon cables can be pre-connected to avoid the need to plug in cables after installation, thus effectively avoiding the inconvenience of plugging in due to insufficient internal space.

[0059] During the assembly process described above, the pre-installed module 120 can be pre-processed and debugged before being assembled with the housing 110. If the image acquisition component 122, laser emitting device 123 or main control component 124 is found to be faulty or its accuracy is not up to standard, the pre-installed module 120 can be maintained directly without having to install each component into the housing 110 one by one and then disassemble and debug it, effectively avoiding repeated disassembly and assembly.

[0060] It should be noted that in scenarios where the laser scanner 100 is used for criminal injury examination, if a laser scanner 100 malfunctions during use, the user must replace or debug it themselves due to the confidentiality requirements of the internal data. During replacement, the user disassembles the corresponding component from another purchased laser scanner 100 and connects it to the faulty device to replace the faulty component. During disassembly, it is not necessary to disassemble each component individually; only the area where the faulty component is located needs to be exposed for replacement. During reassembly, the newly connected component will not affect the modular assembly process of the original device. Thus, simply fixing the newly connected component ensures that the replacement component is stably and reliably mounted within the laser scanner 100. During debugging, the processing and debugging of each functional component can still be completed before installation, avoiding the situation where a single component malfunctions again after initial debugging and installation, requiring disassembly and re-debugging. This further reduces repetitive disassembly and assembly operations during troubleshooting and debugging. Therefore, the modular design of the laser scanner 100 has significant positive benefits for the maintenance, replacement, and debugging of the laser scanner 100 in special scenarios.

[0061] The laser scanner 100 provided in this application embodiment achieves modular assembly of the laser scanner 100 by initially integrating the adapter bracket 121, image acquisition component 122, laser emitting device 123 and main control component 124 into a pre-installed module 120, as described above. This simplifies the disassembly and reassembly steps, reduces repetitive disassembly and reassembly operations during function debugging, thereby reducing the difficulty of maintenance and replacement operations, and significantly improving the maintainability and ease of repair of the laser scanner 100. In addition, the modular design also optimizes the internal space layout and reduces redundant structural components, thereby helping to achieve miniaturization and weight reduction of the laser scanner 100, and thus greatly improving the portability of the laser scanner 100.

[0062] In some embodiments, such as Figure 3 As shown, the adapter bracket 121 has a first side and a second side opposite to each other. The image acquisition component 122 and the laser emitting device 123 are installed on the first side. The first side is positioned and connected to the first cover 111. The main control component 124 is positioned and cooperates with the second side.

[0063] The image acquisition component 122 and the laser emitting device 123 can be installed to the target position on the first side of the adapter bracket 121 by means of threaded connection, snap-fit ​​or hybrid connection, so that after the adapter bracket 121 is assembled with the first cover 111, the image acquisition component 122 and the laser emitting device 123 can be aligned with the target area of ​​the first cover 111, thereby ensuring the positioning accuracy of the image acquisition component 122 and the laser emitting device 123 with the first cover 111.

[0064] The main control component 124 can be arranged at the target position on the second side of the adapter bracket 121 through the matching of positioning post 1211 and positioning hole, positioning protrusion and positioning groove 1101, magnetic matching, guide rail and slide groove matching, or a combination of matching, so that after the first cover 111 and the side frame 112 are assembled, the main control component 124 can be precisely fixedly connected to the target area of ​​the side frame 112, thereby ensuring the positioning accuracy of the main control component 124 and the side frame 112.

[0065] In this embodiment, such as Figure 3 As shown, the adapter bracket 121 has a first side and a second side facing away from each other. The image acquisition component 122 and the laser emitting device 123 are each positioned and installed at the target position on the first side. The initial positioning and fixation of the pre-installed module 120 is achieved through the positioning connection between the first side and the first cover 111. The main control component 124 is positioned on the second side. The further positioning and fixation of the pre-installed module 120 is achieved through the positioning connection between the main control component 124 and the side frame 112.

[0066] The laser scanner 100 provided in this application embodiment achieves dual precise positioning of the pre-installed module 120 through the opposite side layout between the main control component 124, the image acquisition component 122, and the laser emitting device 123. This effectively reduces the offset of each component during assembly, thereby greatly improving the overall assembly accuracy and ensuring the stability of scanning performance. At the same time, it makes full use of the space in the thickness direction of the main control component 124, thereby reducing the excessive occupation of the space in the length and width directions of the main control component 124. This leaves enough space for other components while reducing the overall size, which is beneficial for user portability and operation.

[0067] In some embodiments, such as Figure 4 As shown, the adapter bracket 121 is provided with a positioning post 1211, and the main control component 124 is provided with a positioning hole. The positioning post 1211 is positioned and inserted into the positioning hole.

[0068] The positioning post 1211 can be, but is not limited to, a cylinder, a semi-cylinder, a prism, or an irregular columnar structure. Correspondingly, the positioning hole can also be, but is not limited to, a circular hole, a semi-circular hole, a polygonal hole, or an irregularly shaped hole. This application embodiment does not limit this.

[0069] The positioning post 1211 and the positioning hole can be set one or multiple in a one-to-one correspondence. Multiple means two or more. The specific number depends on the actual needs. This application embodiment does not limit this.

[0070] like Figure 4As shown, during the assembly process of the pre-installed module 120, simply align the positioning hole of the main control component 124 with the positioning post 1211 on the adapter bracket 121 and gently push it along the insertion direction to accurately position the main control component 124.

[0071] The laser scanner 100 provided in this application embodiment achieves the positioning and engagement between the adapter bracket 121 and the main control component 124 through the positioning and insertion design between the positioning post 1211 and the positioning hole. This allows the main control component 124 to be quickly and accurately guided and placed in the predetermined position on the adapter bracket 121 during assembly, providing a preliminary positioning reference for the subsequent connection between the main control component 124 and the side frame 112. This speeds up the assembly process and helps improve the assembly accuracy.

[0072] In some embodiments, such as Figure 4 As shown, the adapter bracket 121 is provided with a plurality of support platforms 1212 spaced apart, each support platform 1212 forming a support surface 1212a facing toward the second cover 113, and the main control component 124 is attached to the support surface 1212a; wherein, at least two support surfaces 1212a are equipped with positioning posts 1211.

[0073] In this context, "multiple" refers to two or more items, and the specific number depends on the actual needs. This application does not impose any restrictions on this.

[0074] As an example, such as Figure 4 As shown, the adapter bracket 121 is provided with four support platforms 1212 spaced apart, and the four support platforms 1212 are respectively supported at the four corners of the main control component 124; among them, the two diagonally arranged support surfaces 1212a are equipped with positioning columns 1211.

[0075] As an example, the adapter bracket 121 is provided with four support platforms 1212 that are spaced apart, and the four support platforms 1212 are respectively supported at the four corners of the main control component 124; wherein, positioning posts 1211 are installed on two adjacent support surfaces 1212a.

[0076] As an example, the adapter bracket 121 is provided with four support platforms 1212 spaced apart, and the four support platforms 1212 are respectively supported at the four corners of the main control component 124; wherein, all support surfaces 1212a are equipped with positioning posts 1211.

[0077] As an example, the adapter bracket 121 is provided with six support platforms 1212 spaced apart, and the six support platforms 1212 are respectively supported at the four corners and the middle of both sides of the main control component 124; wherein, the four support surfaces 1212a located at the four corners are each equipped with positioning posts 1211.

[0078] In this embodiment, such as Figure 4 As shown, the second side of the adapter bracket 121 can be integrally formed with multiple spaced-apart support platforms 1212. Multiple support surfaces 1212a of the multiple support platforms 1212 are flush. The side of the main control component 124 facing away from the second cover 113 can be flat against the multiple support surfaces 1212a, achieving uniform and stable bottom support through surface contact. On at least two of the support platforms 1212, positioning posts 1211 protrude in the direction facing away from the first side. When the main control component 124 is assembled with the adapter bracket 121, the positioning holes of the main control component 124 are first guided and aligned by the positioning posts 1211. Subsequently, the side of the main control component 124 facing away from the second cover 113 can smoothly sit on the support surfaces 1212a of all the support platforms 1212.

[0079] The laser scanner 100 provided in this application embodiment provides stable and uniform support for the main control component 124 through the arrangement of the above-mentioned multiple support platforms 1212, reducing the risk of local deformation of the main control component 124 under stress. At the same time, it also provides a positioning reference surface for the main control component 124, further improving the assembly accuracy between the main control component 124 and the housing 110. Combined with the structural design of at least two support surfaces 1212a on which positioning columns 1211 are installed, the structural integration of positioning columns 1211 and support platforms 1212 is realized, so that positioning and support functions are combined, the structure is more compact, and the miniaturization and weight reduction of the laser scanner 100 are further realized.

[0080] In some embodiments, such as Figure 5 As shown, the main control component 124 has a first assembly structure 12411 protruding from the side opposite to the first cover 111. The first assembly structure 12411 has a first threaded portion. The inner wall of the side frame 112 has a second assembly structure 1121 protruding from it. The second assembly structure 1121 has a second threaded portion. The first threaded portion and the second threaded portion are arranged opposite to each other and connected by a threaded connector 150.

[0081] In this embodiment, such as Figure 5As shown, the main control component 124 has at least two edges on the side opposite to the first cover 111 that can be fixed with a first assembly structure 12411 by welding or screwing. The first assembly structure 12411 can be designed as a boss structure protruding from the edge of the main control component 124. The first assembly structure 12411 is machined with a first threaded portion, which can be a threaded blind hole of the first assembly structure 12411. On the inner wall of the side frame 112, corresponding to the position of the first assembly structure 12411, a second assembly structure 1121 can be integrally formed or separately installed. The second assembly structure 1121 protrudes inward and is provided with a second threaded portion, which can be a threaded through hole of the second assembly structure 1121, so that the second assembly structure 1121 generally forms a threaded sleeve structure.

[0082] During assembly, as the assembly consisting of the first cover 111 and the pre-assembled module 120 is closed toward the side frame 112, the alignment of the first assembly structure 12411 and the second assembly structure 1121 can be observed. When the first assembly structure 12411 and the second assembly structure 1121 are basically aligned, the first threaded part and the second threaded part are also basically aligned. A threaded connector 150 (such as a screw) is screwed in from the second threaded part of the second assembly structure 1121 and finally tightened in the first threaded part of the first assembly structure 12411.

[0083] The laser scanner 100 provided in this application embodiment achieves a positioning connection between the main control component 124 and the side frame 112 through the aforementioned first assembly structure 12411, first threaded portion, second assembly structure 1121, and second threaded portion. This directly anchors the fixing point of the main control component 124 onto the side frame 112 of the housing 110, significantly improving the structural rigidity and seismic resistance of the laser scanner 100. Furthermore, based on the positioning connection between the adapter bracket 121 and the first cover 111, this positioning connection point further provides the final precise positioning and locking of the pre-installed module 120 relative to the side frame 112, thereby reducing the probability of the pre-installed module 120 causing slight movement or abnormal noise within the housing 110. In addition, the detachable nature of the threaded connection improves the convenience of subsequent inspection and maintenance.

[0084] In some embodiments, such as Figure 4 and Figures 6-8 As shown, the main control component 124 includes a PCB board 1241 and a connector 1242 mounted on the PCB board 1241. The side frame 112 is provided with a positioning socket 1122, which is disposed opposite to the connector 1242. The connector 1242 is used to couple and connect with the plug terminal 210 of the external power cord 200 to transmit power and signals. The positioning socket 1122 is used to fit with the plug sleeve 220 of the external power cord 200 with clearance.

[0085] In this embodiment, such as Figure 4 and Figures 6-8 As shown, a standard onboard connector 1242 (such as a direct USB Type-C composite interface) can be installed on the edge of the PCB board 1241. The pins of the connector 1242 can be directly soldered onto the circuit of the PCB board 1241. A positioning hole 1122 can be provided on the side wall of the side frame 112, precisely corresponding to the position of the connector 1242. The shape and size of the positioning hole 1122 are designed according to the shape of the plug sleeve 220 of the external power cable 200. The positioning hole 1122 is usually slightly larger than the plug sleeve 220 so that a gap fit is formed between the positioning hole 1122 and the plug sleeve 220, which facilitates insertion and removal while reducing excessive shaking.

[0086] like Figure 4 and Figures 6-8 As shown, after the pre-installed module 120 is installed into the housing 110, the connector 1242 on the main control component 124 is located exactly behind the positioning socket 1122 on the side frame 112. When the user inserts the external power cord 200 from the outside of the side frame 112, the plug sleeve 220 first enters the positioning socket 1122, which serves as an initial guide and prevents mistaken insertion; as insertion continues, the connector terminal 210 can accurately and smoothly couple with the connector 1242.

[0087] The laser scanner 100 provided in this application embodiment, through the cooperative design between the aforementioned connector 1242 and positioning socket 1122 and the external power cable 200, eliminates the need for intermediate connecting cables or flexible circuit boards from the internal motherboard to the side interface board, thereby reducing potential connection failure points and improving the reliability and signal integrity of the electrical connection. On the other hand, the positioning socket 1122 on the side frame 112 provides precise guidance for the insertion of the external power cable 200, ensuring easy and accurate alignment for each insertion and removal, improving the user experience, and protecting the connector 1242 from damage caused by misalignment or misplacing. Furthermore, the connector 1242 is directly fixed to the PCB board 1241, and the PCB board 1241 is firmly fixed to the side frame 112 through the assembly structure and threaded portion, strengthening the mechanical strength of the entire interface area. The positioning socket 1122 structure of the side frame 112 also forms a protective enclosure for the interface area, thereby effectively improving dustproof and local impact resistance.

[0088] It should be noted that during use, the external power cord 200 of the laser scanner 100 will shake during the scanning action. The frequent shaking and stress on the external power cord 200 can easily damage the connector 1242.

[0089] To address the problem of easy damage to the connector 1242 caused by the swaying of the external power cord 200, embodiments of this application may employ at least one of the following solutions:

[0090] Firstly, in some embodiments, such as Figure 7 As shown, the positioning hole 1122 has a protruding limiting rib 1123 on its hole wall, and the limiting rib 1123 is adapted to abut against the outer wall of the plug sheath 220.

[0091] As an example, the height of the limiting rib 1123 can be approximately the same as the clearance between the positioning socket 1122 and the plug sleeve 220. For example, the clearance between the positioning socket 1122 and the plug sleeve 220 can be 0.1mm. Correspondingly, the height of the limiting rib 1123 can also be set to 0.1mm.

[0092] In this embodiment, such as Figure 7 As shown, the wall of the positioning socket 1122 can be integrally formed with a raised limiting rib 1123. The limiting rib 1123 can extend along the insertion / removal direction, and the inner surface of the limiting rib 1123 can form a contact surface that matches the shape of the outer wall of the plug sleeve 220. When the plug terminal 210 of the external power cord 200 is fully inserted, the outer wall of the plug sleeve 220 abuts against the inner surface of the limiting rib 1123, which can be a slight interference fit. At this time, any radial displacement caused by the cable swing attempting to drive the plug sleeve 220 and the plug terminal 210 will first be blocked and constrained by the limiting rib 1123. The limiting rib 1123 can transfer most of the shaking load to the side frame 112 for bearing and dissipation, and only a small portion of residual micro-movement may be transmitted to the plug terminal 210 through the plug sleeve 220.

[0093] The limiting rib 1123 can be provided in one or more ways. Multiple limiting ribs 1123 can be distributed circumferentially on the wall of the positioning hole 1122. Multiple means two or more. The specific number depends on the actual needs. This application embodiment does not limit this.

[0094] The laser scanner 100 provided in this application embodiment effectively limits the radial displacement and swaying space of the plug sheath 220 within the positioning socket 1122 by contacting and engaging the aforementioned limiting rib 1123 with the outer wall of the plug sheath 220. This indirectly limits and buffers the displacement and stress transmitted to the coupling point between the plug terminal 210 and the plug connector 1242 when the cable is subjected to external force swaying. This significantly reduces the risk of loosening of the plug terminal 210, poor contact, or fatigue damage to the solder joints of the plug connector 1242 caused by cable swaying, thereby greatly improving the durability and electrical connection stability of the external interface in dynamic usage environments.

[0095] Secondly, in some embodiments, such as Figure 8As shown, the positioning socket 1122 has a limiting spring 1124 connected to its wall, and the outer wall of the plug sleeve 220 has a notch, which the limiting spring 1124 is adapted to engage with the notch for limiting.

[0096] In this embodiment, such as Figure 8 As shown, one end of the limiting spring 1124 is connected to the wall of the positioning socket 1122, and the other end can protrude towards the center of the hole to form an elastic latch structure. Correspondingly, an annular notch or multiple partial notches can be opened on the plug sleeve 220 of the external power cord 200 at the position corresponding to the limiting spring 1124. When the user inserts the plug terminal 210 and the plug sleeve 220 into the positioning socket 1122, the plug sleeve 220 first presses the limiting spring 1124 outward, forcing the limiting spring 1124 to elastically deform and retract towards the wall of the positioning socket 1122. When the plug terminal 210 and the plug sleeve 220 are fully inserted, that is, when the plug terminal 210 is fully coupled with the plug 1242, the notch on the plug sleeve 220 moves to the position aligned with the limiting spring 1124. At this point, the limiting spring 1124 quickly resets under its own elastic force, springing into the notch. It usually makes a sound and provides a clear tactile feedback, indicating to the user that it has been correctly locked. To unplug the plug, the user needs to apply additional force to deform the limiting spring 1124 against the wall of the positioning socket 1122 and dislodge it from the notch.

[0097] One or more limiting springs 1124 can be provided. Multiple limiting springs 1124 can be distributed circumferentially on the wall of the positioning socket 1122. In the natural state, the gap between multiple limiting springs 1124 can be smaller than the size of the plug sleeve 220 so that when the plug sleeve 220 is inserted, multiple limiting springs 1124 apply a certain clamping force to the plug sleeve 220. Here, multiple means two or more. The specific number depends on the actual needs. This application embodiment does not limit this.

[0098] It should be noted that the limiting spring 1124 can work together with the limiting rib 1123 to suppress radial sway and axial displacement to the greatest extent and enhance the mechanical locking function.

[0099] The laser scanner 100 provided in this application embodiment, through the aforementioned limiting spring 1124, allows the limiting spring 1124 to elastically engage with the notch when the plug terminal 210 and plug sleeve 220 are fully inserted, forming a limiting fit. This effectively prevents the plug sleeve 220 from loosening from the positioning hole 1122 or undergoing axial displacement during vibration or accidental cable pulling. This effectively maintains the coupling depth and stability between the plug terminal 210 and the connector 1242, significantly limiting and buffering the displacement and stress transmitted to the coupling point between the plug terminal 210 and the connector 1242. This significantly reduces the risk of loosening of the plug terminal 210, poor contact, or fatigue damage to the solder joints of the connector 1242 caused by cable vibration, thereby greatly improving the durability and electrical connection stability of the external interface under dynamic usage environments. Furthermore, the engagement of the limiting spring 1124 with the notch provides clear feedback to the user regarding insertion completion, effectively alleviating poor contact problems caused by incomplete insertion, thus improving the user experience.

[0100] Thirdly, in some embodiments, the maximum gap between the positioning socket 1122 and the plug sleeve 220 is between 0mm and 0.2mm, and the insertion depth of the plug sleeve 220 is not less than 6mm.

[0101] The maximum gap between the positioning socket 1122 and the plug sheath 220 can be 0.05mm, 0.072mm, 0.1mm, 0.16mm, 0.2mm or other values ​​between 0mm and 0.2mm. This application embodiment does not limit this.

[0102] The insertion depth of the plug sheath 220 can be 6mm, 6.5mm, 6.88mm, 7.798mm, 8mm or other values ​​greater than 6mm, and this application embodiment does not limit this.

[0103] Understandably, controlling the mating clearance between the positioning socket 1122 and the plug sleeve 220 to 0mm~0.2mm maintains smooth insertion and removal while reducing wobble space, minimizing unintended radial wobble. Limiting the length of the plug sleeve 220 extending into the positioning socket 1122 to no less than 6mm provides sufficient guidance and contact length, significantly increasing the torque required to tilt or oscillate the plug sleeve 220. The combination of these two factors effectively limits the sway amplitude of the plug sleeve 220 and the mating terminal 210 during scanning.

[0104] The laser scanner 100 provided in this application embodiment controls the maximum mating gap between the positioning socket 1122 and the plug sleeve 220 to between 0mm and 0.2mm, limiting the mating gap to a very small tolerance range. This minimizes the radial wobble space of the plug sleeve 220 within the positioning socket 1122, thereby effectively limiting the swing amplitude of the plug terminal 210. Combined with controlling the insertion depth of the plug sleeve 220 to not less than 6mm, the sufficiently large insertion depth provides a longer guide contact surface and a larger lateral constraint arm, making the plug sleeve 220 more resistant to tipping and swaying when subjected to lateral forces. This minimizes the kinetic energy transmitted from cable swing to the plug 1242, thereby maximizing the dynamic reliability of the interface area.

[0105] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the laser scanner 100 also includes a fan 140.

[0106] The fan 140 is used to drive the gas flow inside the housing 110. The two ends of the side frame 112 are respectively provided with an air inlet 1125 and an air outlet 1126, and the fan 140 is located at at least one of the air inlet 1125 and the air outlet 1126.

[0107] The air inlet 1125 and the air outlet 1126 can be designed as a mesh structure or a grille structure, and this application embodiment does not limit this.

[0108] As an example, such as Figure 6 As shown, the air inlet 1125 and the positioning hole 1122 can be located at the same end of the side frame 112, and the air outlet 1126 can be located at the opposite end of the positioning hole 1122.

[0109] As an example, the air outlet 1126 and the positioning hole 1122 can be located at the same end of the side frame 112, and the air inlet 1125 can be located at the opposite end of the positioning hole 1122.

[0110] As an example, such as Figure 2 and Figure 5 As shown, the fan 140 can be installed at the air outlet 1126.

[0111] As an example, the fan 140 can be located at the air inlet 1125.

[0112] As an example, a fan 140 can be installed at both the air inlet 1125 and the air outlet 1126.

[0113] It should be noted that the installation of the fan 140 shall not interfere with the installation and removal of the pre-installed module 120, nor interfere with the normal function tables of the electronic control components, image acquisition components 122 and laser emitting device 123.

[0114] As an example, such as Figure 2 , Figure 5 and Figure 6 As shown, the fan 140 can be installed inside the air outlet position of the side frame 112, that is, the fan 140 is entirely housed inside the casing 110.

[0115] As an example, the fan 140 can be mounted in the air outlet position of the side frame 112.

[0116] In this embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the fan 140 is installed inside the air outlet 1126. The air inlet 1125 and the air outlet 1126 can be located at both ends of the main heat-generating components such as the main control component 124 and the laser emitting device 123 in the pre-installed module 120. When the fan 140 is working, external cold air is drawn into the housing 110 through the air inlet 1125. The cold air forms a ventilation duct on both sides of the adapter bracket 121, flows over the surface of the heat-generating components such as the main control component 124 and the laser emitting device 123, and carries away the heat. Finally, it becomes hot air and is forcibly discharged from the air outlet 1126.

[0117] The laser scanner 100 provided in this application embodiment effectively solves the problem of heat accumulation generated by electronic components such as the main control component 124 and the laser emitting device 123 during long-term high-load operation by setting up the fan 140, air inlet 1125 and air outlet 1126. This allows the laser scanner 100 to operate within a safe temperature range, thereby improving the working stability and reliability of the laser scanner 100 and extending its service life. Combined with the layout design of the air inlet 1125 and air outlet 1126 located at both ends of the side frame 112, a two-end airflow design is realized. Compared with the side-in-end-out and end-in-side-out airflow designs, this reduces wind resistance, extends the air cooling path, and optimizes the heat dissipation effect.

[0118] In some embodiments, the fan 140 includes a fan body and an elastic sleeve. The housing 110 forms a positioning groove 1101. The fan body is interference-fitted into the elastic sleeve, and the elastic sleeve is elastically compressed between the groove wall of the positioning groove 1101 and the fan body.

[0119] The elastic sheath can be made of damping materials such as silicone, rubber or polyurethane, and this application does not limit this.

[0120] In this embodiment, the inner cavity size of the elastic sleeve can be slightly smaller than the outer contour size of the fan body, and it is tightly wrapped around the fan body by interference fit to form the first layer of vibration damping. A positioning groove 1101 can be constructed in the housing 110, and the size of the positioning groove 1101 can be slightly smaller than the outer contour size of the fan body with the elastic sleeve in its natural state.

[0121] During assembly, the fan body with the elastic sleeve can be pressed axially into the positioning groove 1101. During this process, the elastic sleeve is squeezed by the groove wall of the positioning groove 1101, undergoes uniform elastic deformation and fills the groove space, thereby forming a second layer of vibration damping between the fan body and the rigid groove wall of the positioning groove 1101, and achieving a screwless and stable fixation by relying on friction and elasticity.

[0122] The laser scanner 100 provided in this application embodiment, through the above-mentioned structure design of the fan body being interference-fitted into the elastic sleeve, can significantly attenuate the vibration energy generated when the fan body rotates at high speed, and block the transmission path of vibration to the housing 110 structure, thereby greatly reducing the overall operating noise and improving the user experience. Combined with the assembly design of the elastic sleeve being elastically compressed between the groove wall of the positioning groove 1101 and the fan body, the compression deformation of the elastic sleeve provides a uniform and durable holding force, significantly reducing the risk of the fan 140 loosening under long-term vibration, realizing screwless installation of the fan 140, thereby simplifying the assembly process.

[0123] In some embodiments, such as Figure 5 As shown, the inner wall of the first cover 111 protrudes towards the direction of the second cover 113 and is provided with a first boss 11111. The inner wall of the second cover 113 protrudes towards the direction of the first cover 111 and is provided with a second boss 1131. The first boss 11111 and the second boss 1131 form at least part of the groove wall of the positioning groove 1101. The elastic sleeve is elastically compressed between the first boss 11111 and the second boss 1131.

[0124] In this embodiment, such as Figure 5As shown, when the first cover 111 and the second cover 113 are closed by the side frame 112, the first boss 11111 and the second boss 1131 are spatially opposite to each other to form the opposite side walls of the positioning groove 1101, and the inner wall of the side frame 112 can form the bottom wall of the positioning groove 1101. When installing the fan 140, the fan body fitted with an elastic sleeve is pre-placed on the first boss 11111. During the closing of the housing 110, the second boss 1131 presses against the elastic sleeve. When the housing 110 is completely closed and locked by the connector, the first boss 11111 and the second boss 1131 tightly compress the elastic sleeve, and at the same time, the inner wall of the side frame 112 forms the bottom of the positioning groove 1101. Finally, the fan 140 is firmly and elastically pressed into the positioning groove 1101 formed by the first boss 11111, the second boss 1131 and the side frame 112.

[0125] As an example, the inner wall of the side frame 112 may also be provided with ribs for positioning and mating with the fan 140, so as to further improve the assembly accuracy of the fan 140.

[0126] The laser scanner 100 provided in this application embodiment, through the structural design of the elastic sleeve elastically compressed between the first boss 11111 and the second boss 1131, allows the fixed assembly of the fan 140 to be synchronized with the closing action of the housing 110, eliminating the need for a separate installation step. This further simplifies the final assembly process, thereby further improving assembly efficiency.

[0127] In some embodiments, such as Figure 1 and Figure 3 As shown, the image acquisition component 122 includes a first black and white camera 1221, a second black and white camera 1222, and a color camera 1223, which are mounted separately on the adapter bracket 121. The color camera 1223 and the laser emitting device 123 are located between the first black and white camera 1221 and the second black and white camera 1222. The first black and white camera 1221, the second black and white camera 1222, the color camera 1223, and the laser emitting device 123 are arranged in a straight line with intervals, so that the dimension of the housing 110 along the arrangement direction is the length of the housing 110.

[0128] It should be noted that the first cover 111 is provided with a first through hole, a second through hole and a third through hole. The first through hole is arranged opposite to the first black and white camera 1221, the second through hole is arranged opposite to the second black and white camera 1222, and the third through hole is arranged opposite to the color camera 1223. The common shooting range of the first black and white camera 1221 and the second black and white camera 1222 can cover the scanning range of the laser emitting device 123, and the shooting range of the color camera 1223 can cover the scanning range of the laser emitting device 123.

[0129] As an example, such as Figure 1 and Figure 3 As shown, the first cover 111 may include a main cover body 1111 and a transparent protective window 1112. At least a portion of the first through hole, the second through hole and the third through hole may be covered by the transparent protective window 1112. The transparent protective window 1112 can protect the corresponding camera and also beautify the overall appearance of the device.

[0130] For example, in some embodiments, such as Figure 1 and Figure 3 As shown, the first and second through holes are provided with the transparent protective window 1112 to protect the lenses of the first black and white camera 1221 and the second black and white camera 1222.

[0131] In actual implementation, the optical axes or center lines of the first monochrome camera 1221, the second monochrome camera 1222, the color camera 1223, and the laser emitting device 123 are strictly arranged along the same straight line at intervals; alternatively, there may be slight misalignment between the optical axes or center lines of the first monochrome camera 1221, the second monochrome camera 1222, the color camera 1223, and the laser emitting device 123, as long as they are generally arranged in a straight line. This embodiment of the application does not impose any restrictions on this. The specific arrangement order may be: first monochrome camera 1221 - laser emitting device 123 - color camera 1223 - second monochrome camera 1222. Of course, the relative positions of the laser emitting device 123 and the color camera 1223 can be adjusted according to the optical design, but they are always kept between the first monochrome camera 1221 and the second monochrome camera 1222. The spacing between the components is minimized to only meet the requirements of non-obstruction of the optical field of view and necessary structural strength.

[0132] Understandably, the overall shape of the housing 110 is determined by the aforementioned linear layout. Since the optical components are the core of the device and their dimensions are relatively fixed, the linear arrangement of the optical components requires the housing 110 to have sufficient extension space in the corresponding direction (i.e., the length direction), while it can be made very compact in the vertical direction (i.e., the width direction). Therefore, the housing 110 is naturally designed as a long strip shape with the arrangement direction as its length direction.

[0133] The laser scanner 100 provided in this application embodiment, through the layout design of the first black and white camera 1221, the second black and white camera 1222, the color camera 1223 and the laser emitting device 123 arranged at intervals along a straight line, makes the size of the housing 110 that houses these optical devices along the arrangement direction the main length dimension of the housing 110, thereby shaping a long and narrow device shape. The length direction of the housing 110 naturally becomes the main direction for the user to hold, so that the device can comfortably fit the palm, thereby facilitating one-handed operation and enabling the user to hold it stably for a long time and perform scanning operations, thus optimizing the handheld experience.

[0134] It should be noted that, in the application of the laser scanner in criminal injury examination scenarios, the first black-and-white camera 1221 and the second black-and-white camera 1222 can capture high-resolution black-and-white images to capture quantitative data such as the length, width, depth, indentation volume, and wound area of ​​the injury. Meanwhile, the color camera 1223 can capture high-resolution black-and-white images to capture true color and texture information. Thus, bruises, swelling, and changes in wound color can be accurately recorded, avoiding the loss of these details that would occur if only a black-and-white camera were used. The combination of both significantly enhances the authenticity of visual evidence and helps to provide a more comprehensive injury analysis.

[0135] In some embodiments, such as Figures 1-3 As shown, the outer wall of the housing 110 is provided with anti-slip texture 1102.

[0136] The anti-slip texture 1102 can take various forms, including but not limited to: regularly arranged dot-like protrusions, interlaced grid-like grooves, or wavy or sawtooth stripes extending along the grip direction, etc. This application embodiment does not limit this.

[0137] The anti-slip texture 1102 can be integrally molded with the casing 110, providing functional anti-slip while also becoming part of the appearance.

[0138] The anti-slip texture 1102 is typically applied to areas that the user's palm and fingers primarily contact when holding the device. For example, the anti-slip texture 1102 can be formed by molding or subsequent processing on the outer wall of the housing 110, particularly on the outer wall of the side frame 112 that forms the main grip area, and on the edge areas that may include the first cover 111 and / or the second cover 113.

[0139] As an example, such as Figure 1 and Figure 2 As shown, the junction area between the side frame 112 and the first cover 111 may be provided with an anti-slip texture 1102.

[0140] For example, in some embodiments, such as Figure 3 As shown, the anti-slip texture 1102 can be integrally formed with the first cover 111.

[0141] For example, in some other embodiments, the anti-slip texture 1102 may also be integrally formed with the side frame 112.

[0142] The laser scanner 100 provided in this application embodiment, by setting the anti-slip texture 1102, increases the coefficient of friction between the hand and the surface of the casing 110, effectively reducing the risk of the device slipping from the hand due to hand sweat, oil stains or accidental contact, thereby protecting the internal precision optical and electronic modules, avoiding high maintenance costs caused by accidental drops, and maintaining the continuity and stability of scanning work.
