[0044] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0045] The button structure of this utility model is described below with reference to the accompanying drawings.

[0046] like Figures 1 to 5As shown, this utility model provides a button structure 100, which includes a mounting bracket 10, a button module 20, and a pressing component 30. The mounting bracket 10 has a through hole 11. The button module 20 is located on one side of the mounting bracket 10 and has a button component 21 corresponding to the through hole 11. The pressing component 30 includes a pressing block 31 and an elastic sheet 32. The pressing block 31 is located on the side of the mounting bracket 10 away from the button component 21. The pressing block 31 has an extension post 311, which passes through the through hole 11 and is used to push the button component 21. The elastic sheet 32 ​​is sleeved on the extension post 311 and is located between the pressing block 31 and the mounting bracket 10.

[0047] It should be noted that the button structure 100 of this utility model can be installed on the scanner 200 to turn the scanner 200 on or off. The scanner 200 can be a structured light 3D scanner, a laser 3D scanner, or a lidar scanner, etc. This utility model does not limit the type of scanner 200 on which the button structure 100 is applied. This utility model embodiment is only described by taking the installation of the button structure 100 on the scanner 200 as an example.

[0048] Specifically, a button module 20 is provided on one side of the mounting bracket 10, and the button component 21 of the button module 20 is set corresponding to the through hole 11 on the mounting bracket 10. A pressing block 31 is provided on the other side of the mounting bracket 10. An extension post 311 is provided on the side of the pressing block 31 facing the mounting bracket 10. The extension post 311 passes through the through hole 11, and an elastic sheet 32 ​​is sleeved on the extension post 311. When the pressing block 31 is pressed towards the mounting bracket 10, the pressing block 31 drives the extension post 311 to move towards the button component 21, so that the extension post 311 abuts against the button component 21 and pushes to trigger the button component 21. The button component 21 responds to the pushing action of the extension post 311 to open or close. The scanner 200 is closed. The button structure 100 has an extension post 311 on the pressing block 31, which pushes and triggers the button component 21. This shortens the pressing stroke of the pressing block 31, speeds up the response speed of the button component 21, and improves the pressing sensitivity, making it easier for users to judge the on / off state of the scanner 200. In addition, an elastic sheet 32 ​​is provided between the pressing block 31 and the mounting bracket 10. When the pressing block 31 moves toward the mounting bracket 10, it cooperates with the mounting bracket 10 to squeeze the elastic sheet 32. The elastic sheet 32 ​​plays a role in buffering and feedback, which not only reduces pressing noise, but also enhances the user's pressing feel and improves the user experience by acting on the pressing block 31 with the elastic restoring force of the elastic sheet 32.

[0049] In addition, it is understandable that the elastic restoring force of the elastic sheet 32 ​​can push the pressing block 31 to move away from the mounting bracket 10, thereby realizing the automatic reset of the pressing block 31; and the button component 21 can be a button component used in the prior art to control the on and off of the circuit, which closes the circuit when pressure is applied to the button component 21 and disconnects the circuit when the pressure is removed, thereby triggering the scanner 200 to turn on or off.

[0050] In this embodiment of the invention, the elastic sheet 32 ​​includes a pressing deformation portion 321, which protrudes toward the pressing block 31. Figures 3 to 6 As shown, the elastic sheet 32 ​​is disposed between the pressing block 31 and the mounting bracket 10 and has a pressing deformation part 321 protruding towards the pressing block 31. The pressing deformation part 321 increases the contact area between itself and the pressing block 31, enhances the pressing feedback, and further improves the pressing feel. The pressing deformation part 321 can elastically deform under compression and apply elastic restoring force to the pressing block 31. The pressing deformation part 321 rebounds away from the mounting bracket 10 so that the pressing block 31 can quickly reset, effectively preventing the pressing block 31 from getting stuck during reset. In addition, the elastic sheet 32 ​​can absorb the pressing impact of the pressing block 31, playing a buffering role and preventing the pressing block 31 from colliding with the mounting bracket 10 and generating pressing noise, thus improving the user experience.

[0051] In this embodiment of the utility model, a mounting groove 12 is provided on the side of the mounting bracket 10 facing away from the button component 21, a through hole 11 is provided on the bottom wall of the mounting groove 12, the pressing block 31 is movably disposed in the mounting groove 12, and the elastic sheet 32 ​​also includes a positioning mounting part 322, which extends along the edge of the pressing deformation part 321 and is adapted to the mounting groove 12.

[0052] like Figure 6 and Figure 7 As shown, the pressing block 31 is installed in the mounting groove 12 and can move towards or away from the bottom wall of the mounting groove 12 to drive the extension column 311 to push and trigger the button component 21, or drive the extension column 311 to move away from the button component 21. The elastic sheet 32 ​​is disposed between the pressing block 31 and the bottom wall of the mounting groove 12. The mounting groove 12 serves to accommodate the elastic sheet 32 ​​and the pressing block 31, preventing the elastic sheet 32 ​​from being exposed or falling off, improving the appearance and structural stability. Furthermore, the positioning mounting part 322 of the elastic sheet 32 ​​surrounds the outer periphery of the pressing deformation part 321. The edge of the positioning mounting part 322 is adapted to the side wall of the mounting groove 12, so that the positioning mounting part 322 can be stably installed in the mounting groove 12, further preventing the elastic sheet 32 ​​from falling off from the mounting groove 12, making the structure stable and reliable.

[0053] In this embodiment of the utility model, the pressing block 31 is provided with a buckle 312, and the bottom wall of the mounting groove 12 is provided with a slot 121. The buckle 312 passes through the slot 121 and is engaged with the side of the mounting bracket 10 facing away from the pressing block 31. The number of buckles 312 is set to be multiple, and the multiple buckles 312 are arranged circumferentially at intervals. The number of slots 121 is the same as the number of buckles 312 and is arranged one-to-one.

[0054] like Figures 4 to 7 As shown, the bottom wall of the mounting groove 12 is provided with multiple slots 121, which surround the outer periphery of the through hole 11. The pressing block 31 is provided with a buckle 312 corresponding to each slot 121. The buckle 312 passes through the slot 121 and is engaged with the mounting bracket 10, which makes assembly convenient and quick and effectively prevents the pressing block 31 from falling out of the mounting groove 12, further improving the structural stability. In addition, the pressing block 31 can drive the buckle 312 to move relative to the mounting bracket 10. When the pressing deformation part 321 pushes the pressing block 31 to reset, the buckle 312 can engage with the mounting bracket 10 to limit the rebound stroke of the pressing block 31, prevent the pressing block 31 from loosening, and ensure a stable and reliable connection.

[0055] In a preferred embodiment of this utility model, the number of buckles 312 is set to four. The four buckles 312 are arranged circumferentially at intervals on the pressing block 31 and surround the outer periphery of the extension column 311. The number of slots 121 is consistent with the number of buckles 312 and is arranged one-to-one. The four buckles 312 are synchronously engaged on the mounting bracket 10, which effectively prevents the pressing block 31 from tilting or loosening, avoids the extension column 311 from accidentally touching the button component 21 due to the tilt of the pressing block 31, and further improves the assembly stability.

[0056] Furthermore, such as Figures 4 to 6 As shown, the extension post 311 and the buckle 312 are integrally formed on the pressing block 31, which has the advantages of easy manufacturing, saving assembly steps and eliminating assembly errors. When the pressing block 31 is pressed towards the mounting bracket 10, the extension post 311 moves synchronously with the pressing block 31 and directly abuts against the button component 21, avoiding response delay caused by intermediate deviation and improving the switching sensitivity of the scanner 200.

[0057] In this embodiment of the utility model, the positioning mounting part 322 is provided with positioning grooves 3221, and the number of positioning grooves 3221 is the same as the number of buckles 312 and they are set one-to-one. For example Figure 6As shown, the positioning mounting part 322 has a positioning groove 3221 for each buckle 312 to pass through. The buckle 312 cooperates with the positioning groove 3221 to limit the installation position of the positioning mounting part 322, so that the positioning mounting part 322 can be positioned between the pressing block 31 and the bottom wall of the mounting groove 12, preventing the pressing deformation part 321 from rotating, shifting or shaking, and further improving the structural stability.

[0058] Furthermore, a clearance groove 313 is provided on the side of the pressing block 31 facing the pressing deformation part 321, the pressing deformation part 321 extends into the clearance groove 313, and the extension post 311 is provided on the bottom wall of the clearance groove 313. Figures 4 to 6 As shown, the relief groove 313 is recessed in the direction away from the pressing deformation part 321, so that the pressing deformation part 321 can extend into the relief groove 313, which improves the ease of assembly and further prevents the pressing deformation part 321 from being tilted relative to the pressing block 31, thus ensuring stable assembly of the structure.

[0059] In this embodiment of the utility model, the button structure 100 further includes a protective shell 40, which is connected to the mounting bracket 10 and forms an accommodating space 41. The button module 20 further includes a button motherboard 22, which is disposed on the mounting bracket 10 and located in the accommodating space 41. The button components 21 are disposed on the button motherboard 22 and electrically connected to the button motherboard 22.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, a protective shell 40 is provided on one side of the mounting bracket 10, and an accommodating space 41 is formed between the protective shell 40 and the mounting bracket 10. The button main board 22 is located in the accommodating space 41 and connected to the mounting bracket 10. The protective shell 40 serves to protect the button main board 22 and improves the appearance. In addition, the button component 21 is electrically connected to the button main board 22. When the button component 21 is pushed by the extension post 311, it closes and connects the circuit on the button main board 22, and when the extension post 311 releases the pushing force, it disconnects the circuit on the button main board 22, thereby triggering the scanner 200 to turn on or off, realizing the rapid switching of the scanner 200 with sensitive and reliable response.

[0061] Furthermore, the mounting bracket 10 is provided with a connecting post 13, which passes through the button motherboard 22 and the protective shell 40 and is used to connect with the fastener 14. Figures 1 to 3As shown, when assembling the button structure 100, the elastic sheet 32 ​​is first fitted onto the extension post 311, so that the pressing deformation part 321 extends into the relief groove 313, preventing the pressing deformation part 321 from detaching from the pressing block 31 during the pressing process. Then, multiple buckles 312 are passed through the corresponding slots 121 to assemble the pressing block 31 and the elastic sheet 32 ​​into the mounting groove 12, preventing the pressing block 31 from tilting or loosening during the pressing process. The button main board 22 is fitted onto the connecting post 13, so that the button component 21 is set corresponding to the extension post 311, making it easy for the extension post 311 to push and trigger the button component 21, realizing the rapid opening or closing of the scanner 200. Finally, the protective shell 40 is fitted onto the connecting post 13, and the fastener 14 is inserted into the connecting post 13 and connected to the connecting post 13 to fix the protective shell 40. The button structure 100 is easy and quick to assemble, has a stable and reliable structure, and has the advantages of fast response, low noise, and good pressing feel. In addition, the connecting post 13 can be a BOSS post in the prior art, and the fastener 14 can be a countersunk screw in the prior art. The fastener 14 extends into the connecting post 13 and is threaded to the connecting post 13, which further improves the ease of assembly. Moreover, the fastener 14 uses a countersunk screw so that the screw head can be flush with the surface of the protective shell 40, which further improves the appearance.

[0062] In the embodiments of this utility model, such as Figures 4 to 6 As shown, the elastic sheet 32 ​​has a through hole 323 for the extension post 311 to pass through. The through hole 323 and the extension post 311 are designed to be interference fit, which improves the connection stability between the extension post 311 and the elastic sheet 32, effectively prevents the elastic sheet 32 ​​from loosening or sliding relative to the extension post 311, and ensures stable and reliable rebound.

[0063] In this embodiment of the invention, the elastic sheet 32 ​​is integrally injection molded, and the elastic sheet 32 ​​is made of thermoplastic polyurethane elastomer (TPU) or silicone material. Specifically, the pressing deformation part 321 and the positioning and mounting part 322 are integrally molded, which has the advantages of easy manufacturing, saving assembly steps and eliminating assembly errors. Moreover, the elastic sheet 32 ​​can be manufactured using the injection molding process in the prior art, which improves the dimensional accuracy and surface quality of the elastic sheet 32. In addition, the TPU material of the elastic sheet 32 ​​has the advantages of high strength and high elasticity, which improves the tensile strength, wear resistance and elastic recovery of the elastic sheet 32, enabling the elastic sheet 32 ​​to withstand large loads and impacts and to quickly rebound and push the pressing block 31 to reset after being pressed. The silicone material of the elastic sheet 32 ​​has high elastic recovery ability, excellent fatigue resistance and deformation range, which enables the elastic sheet 32 ​​not only to rebound quickly, but also to deform repeatedly, extending its service life.
