[0026] According to the first aspect of the present invention, an oral scanner mounting structure includes a housing 10, an electro-optical component 20, and an elastic component 30.

[0027] The specific structure of the above-described components of the oral scanner mounting structure according to this embodiment will be described below.

[0028] In this embodiment, as Figures 1 to 3 As shown, a mounting position 100 is formed inside the housing 10. The mounting position 100 can be a groove-like structure or a hole-like structure. A protrusion is provided on the mounting position 100, and the protrusion can be a block-like structure. An electro-optical component 20 is disposed on the mounting position 100. The electro-optical component 20 can be a digital microreflector. A groove is formed on the circumferential edge of the electro-optical component 20 for the protrusion to extend into. The protrusion and the groove cooperate to position the electro-optical component 20 in the mounting position 100.

[0029] In this embodiment, as Figures 2 to 4 As shown, the circumferential edge of the electro-optic component 20 includes a first wall portion 21 and a second wall portion 22 arranged at an angle to each other. The circumferential edge of the electro-optic component 20 can be a polygonal structure, such as a rectangular structure. When the circumferential edge of the electro-optic component 20 is rectangular, the first wall portion 21 and the second wall portion 22 are arranged perpendicular to each other.

[0030] like Figures 2 to 4 As shown, the elastic component 30 includes an independently configured first elastic element 31 and a second elastic element 32, forming a separate structure that is not connected to each other. The first elastic element 31 is sandwiched between the mounting position 100 and the first wall portion 21, and the second elastic element 32 is sandwiched between the mounting position 100 and the second wall portion 22. Thus, the first elastic element 31 and the second elastic element 32 are used to elastically fix the sidewalls of the electro-optical component 20 in different orientations, satisfying the installation requirements of the electro-optical component 20 while also allowing the electro-optical component 20 to move due to thermal expansion and contraction in the mounting position 100. The independent configuration of the first elastic element 31 and the second elastic element 32 ensures that they do not interact with each other, allowing the electro-optical component 20 to move freely after thermal expansion and contraction, which is beneficial for imaging stability and improves imaging efficiency.

[0031] like Figure 2 As shown, in the circumferential direction of the electro-optic component 20, a groove is disposed between the portion of the first wall 21 that abuts against the first elastic member 31 and the portion of the second wall 22 that abuts against the second elastic member 32, so that the first elastic member 31 and the second elastic member 32 are respectively located on both sides of the groove, so that the electro-optic component 20 is subjected to uniform force, improving the installation stability of the electro-optic component 20 and ensuring the installation accuracy requirements of the electro-optic component 20.

[0032] In a preferred embodiment, such as Figures 2 to 4As shown, the length of the first wall portion 21 is smaller than the length of the second wall portion 22. A groove is formed by the inward recess of the first wall portion 21, such that the groove is located at the end of the electro-optical component 20 along its length, and the protrusion positions it along the length of the electro-optical component 20. The second elastic member 32 abuts against the second wall portion 22 at the middle position along its length, such that the contact point between the second elastic member 32 and the second wall portion 22 is located at the middle of the electro-optical component 20 along its length, resulting in balanced forces and preventing the electro-optical component 20 from becoming misaligned, which would affect imaging.

[0033] Furthermore, in this embodiment, as Figures 2 to 4 As shown, the first wall portion 21 includes a first side 201 and a third side 203 disposed opposite to each other; the second wall portion 22 includes a second side 202 and a fourth side 204 disposed opposite to each other, the second side 202 and the fourth side 204 being perpendicular to the first side 201 and the third side 203, respectively; the first side 201, the second side 202, the third side 203 and the fourth side 204 are connected sequentially to form the circumferential edge of the electro-optical component 20. The first elastic member 31 and the second elastic member 32, as described above, can be mounted on the first side 201 and the second side 202, or on the second side 202 and the third side 203, or on the third side 203 and the fourth side 204, or on the fourth side 204 and the first side 201, respectively.

[0034] In this embodiment, as Figures 2 to 4 As shown, the protrusion includes a first protrusion 11 and a second protrusion 12; the first protrusion 11 and the second protrusion 12 are spaced apart in the length direction of the electro-optical component 20, and the groove includes a first groove 211 into which the first protrusion 11 extends and a second groove 212 into which the second protrusion 12 extends. The first groove 211 and the second groove 212 are disposed opposite to each other on both sides of the electro-optical component 20 to improve positioning reliability. Furthermore, in this embodiment, as Figure 4 As shown, the first groove 211 and the second groove 212 have different shapes. For example, the corner of the groove wall of one groove is set as an arc, and the corner of the groove wall of the other groove is bent to form an edge. The shape of the first protrusion 11 is adapted to the shape of the first groove 211, that is, the shape of the outer edge of the first protrusion 11 facing the first groove 211 is the same as the shape of the groove wall of the first groove 211. The shape of the second protrusion 12 is adapted to the shape of the second groove 212, that is, the shape of the outer edge of the second protrusion 12 facing the second groove 212 is the same as the shape of the groove wall of the second groove 212. This plays a role in preventing mistakes, preventing the electronic optical component 20 from being installed backwards, and improving assembly efficiency.

[0035] In a first alternative implementation, such as Figures 2 to 4As shown, the first elastic member 31 and / or the second elastic member 32 are formed into a U-shaped structure with two legs 301 and an opening 302 between the two legs 301. One leg 301 abuts against the side wall of the mounting position 100, and the other leg 301 has an abutment portion 303 protruding toward the electro-optical component 20. Specifically, the two legs 301 are formed into strip structures spaced apart from each other. One end of the two legs 301 is connected in the length direction, and the other end forms an opening 302. When the electro-optical component 20 undergoes thermal expansion and contraction, the distance between the two legs 301 increases or decreases, thereby elastically fixing the electro-optical component 20 to the mounting position 100.

[0036] In this embodiment, as Figure 2 As shown, when the second elastic member 32 is formed into a U-shaped structure, the abutment portion 303 is located at the middle position in the length direction of the second wall portion 22, thus ensuring force balance, reliable abutment, and preventing the electro-optical component 20 from becoming skewed.

[0037] When both the first elastic element 31 and the second elastic element 32 are formed into a U-shaped structure, such as Figure 2 As shown, the opening 302 of the first elastic member 31 is oriented toward the first protrusion 11, and the opening 302 of the second elastic member 32 is oriented away from the first protrusion 11 and toward the second protrusion 12, so that the openings 302 of the first elastic member 31 and the second elastic member 32 are not opposite to each other, which is beneficial to improving the reliability and stability of the elastic fixation.

[0038] In a second alternative implementation, such as Figure 5 As shown, Figure 5 The image shows either the first elastic element 31 or the second elastic element 32 in the elastic component 30. The first elastic element 31 and / or the second elastic element 32 are formed into a ring structure. The outer ring walls of the ring structure that are opposite to each other abut against the side wall of the mounting position 100 and the circumferential edge of the electro-optic component 20, respectively. When the electro-optic component 20 undergoes thermal expansion and contraction, it will press the outer ring wall of the ring structure, causing the first elastic element 31 and / or the second elastic element 32 to deform and store energy. In this way, the electro-optic component 20 is elastically fixed on the mounting position 100.

[0039] Preferably, the first elastic element 31 and / or the second elastic element 32 of the annular structure are formed into an elliptical annular structure, with the two ends of the ellipse in the direction of the minor axis abutting against the side wall of the mounting position 100 and the circumferential edge of the electro-optic component 20, respectively. This increases the contact area between the first elastic element 31 and / or the second elastic element 32 and the housing 10 or the optical component, thereby improving the reliability of the elastic fixation.

[0040] In a third alternative implementation, such as Figure 6 As shown, Figure 6The diagram shows either the first elastic element 31 or the second elastic element 32 in the elastic component 30. The first elastic element 31 and / or the second elastic element 32 include a base 311 and a telescopic portion 312. The base 311 is formed as a hollow block structure, and the telescopic portion 312 is formed as a short pin structure. The base 311 abuts against the side wall of the mounting position 100, and an elastic module, which can be a spring, is disposed inside the base 311. One end of the telescopic portion 312 abuts against the elastic module, and the other end abuts against the circumferential edge of the electro-optical component 20. When the electro-optical component 20 undergoes thermal expansion and contraction, it drives the telescopic portion 312 to move towards or away from the base 311, thereby compressing or releasing the elastic module. This achieves the elastic fixation of the electro-optical component 20 on the mounting position 100. A portion of the telescopic portion 312 can extend into the base 311, thus preventing the base 311 and the telescopic portion 312 from detaching.

[0041] Preferably, multiple telescopic portions 312 are provided on the base 311, and the multiple telescopic portions 312 are arranged in a linear interval, and the arrangement direction of the multiple telescopic portions 312 is the same as the extension direction of the first wall portion 21 or the second wall portion 22, thereby improving the reliability of elastic fixation.

[0042] In a preferred embodiment, the first elastic member 31 and the second elastic member 32 have the same structure; for example, the first elastic member 31 and the second elastic member 32 are both as shown in the figure. Figure 2 The U-shaped structure shown, or all of them are as follows Figure 5 The ring structure shown, or all of them are as follows Figure 6 The combined structure shown includes a base 311 and a telescopic part 312, so that there is no need to deliberately distinguish between the first elastic element 31 and the second elastic element 32 during assembly, thus improving assembly efficiency.

[0043] Furthermore, in this embodiment, such as Figures 1 to 3 As shown, the scanning head assembly structure also includes a cable 40 and a clamping member 50. The cable 40 is disposed on the side of the electro-optical component 20 facing the outside of the mounting position 100 and connected to the electro-optical component 20. The housing 10 has a clearance portion 101 communicating with the mounting position 100. The clearance portion 101 can be formed as a recessed groove structure or a hole structure, so that part of the cable 40 can extend out of the mounting position 100 from the clearance portion 101, thereby avoiding compression of the cable 40 after the clamping member 50 is installed. The clamping member 50 is installed on the housing 10 and closes at least part of the mounting position 100, thus limiting the cable 40 and the electro-optical component 20 and preventing the cable 40 and the electro-optical component 20 from falling off the mounting position 100.

[0044] Furthermore, such as Figure 1As shown, the clamping plate is fixed to the outer surface of the housing 10 by fasteners such as screws. Preferably, the clamping member 50 is formed as a strip-shaped plate structure, and fasteners are used to install it on the housing 10 at both ends of the clamping member 50 in the length direction, so that the clamping member 50 does not obstruct or avoid space, and meets the bending requirements of the cable 40.

[0045] According to the present invention, the scanning electron microscope (SEM) mounting structure has a mounting position formed inside the housing, and a protrusion is provided on the mounting position. An electro-optical component is mounted on the mounting position, and a groove is formed on the circumferential edge of the electro-optical component for the protrusion to extend into, thus achieving positioning of the electro-optical component. The circumferential edge of the electro-optical component includes a first wall portion and a second wall portion arranged at an angle to each other. The elastic component includes a first elastic member and a second elastic member independently arranged. The first elastic member is clamped between the mounting position and the first wall portion, and the second elastic member is clamped between the mounting position and the second wall portion. This allows the first and second elastic members to elastically fix the sidewalls of the electro-optical component in different orientations, satisfying installation requirements while also allowing the electro-optical component to shift due to thermal expansion and contraction within the mounting position, which is beneficial for imaging stability and improves imaging efficiency. In the circumferential direction of the electro-optical component, a groove is provided between the portion of the first wall portion that abuts against the first elastic member and the portion of the second wall portion that abuts against the second elastic member, improving the installation stability of the electro-optical component and ensuring the installation accuracy requirements of the electro-optical component.

[0046] The intraoral scanning device provided by this utility model includes the above-mentioned intraoral scanning mounting structure, and thus has all the beneficial effects of the intraoral scanning mounting structure, which will not be repeated here.
