Description

Technical Field

[0001] The embodiments of this application relate to the field of electronic device technology, and more specifically, the embodiments of this application relate to a scanning translation pen. Background Technology

[0002] This section is intended to provide background or context for the embodiments of this application as set forth in the claims. The description herein is not intended to be a prior art simply because it is included in this section.

[0003] A scanning translation pen is an electronic device that uses scanning to acquire information such as text or images from a scanned medium and then processes this information through translation or other methods.

[0004] In related technologies, one type of scanning translation pen has a pressure detection component installed on the side wall of the housing. The pressure detection component controls the scanning translation pen to turn on the scanning function by detecting the slight deformation generated by the side wall of the housing.

[0005] Pressure detection components are typically fixed to the sidewall of the housing using high-temperature bonding. Because the sidewall is relatively thin, to prevent deformation of the housing sidewall under high temperatures when the pressure detection component is directly bonded to it, a groove is usually machined into the sidewall. An aluminum block is then fixed into this groove, and the aluminum block is bonded to the pressure detection component using high-temperature bonding. Since the bonding between the aluminum block and the housing does not require high temperatures, the sidewall of the housing will not deform due to temperature variations. However, this type of scanning translation pen has a complex manufacturing process and is relatively expensive. Summary of the Invention

[0006] A pressure detection component is installed on the side wall of the scanner's housing. This component controls the scanner to activate its scanning function by detecting minute deformations in the side wall of the housing. This is an existing technology.

[0007] However, in related technologies, the scanning translation pen with this structure has a complex process and relatively high cost, which is a very troublesome process.

[0008] Therefore, there is a great need for an improved scanning translation pen to simplify the process and reduce costs.

[0009] In this context, embodiments of this application anticipate providing a scanning translation pen, comprising:

[0010] case;

[0011] The pen holder is located at the front end of the housing;

[0012] A pressure detection component, wherein at least the detection part of the pressure detection component is disposed on the pen tip holder, for detecting the deformation of the pen tip holder when the pen tip holder is pressed and outputting a detection signal;

[0013] The main circuit board is located inside the housing and is electrically connected to the pressure detection component to receive the detection signal and control the scanning translation pen to turn on the scanning function according to the detection signal.

[0014] In one embodiment, the housing has a light-transmitting window, the pen holder includes a connecting portion and two supporting portions, the two supporting portions are respectively disposed on opposite sides of the light-transmitting window along the width direction of the scanning translation pen, the connecting portion is located between the two supporting portions and avoids the light-transmitting window, and the pressure detection component has at least a detection portion disposed on the connecting portion.

[0015] The detection part is located on the connection between the two support parts. The detection part of the pressure detection component is roughly located in the middle of the scanning translation pen along the width direction. Therefore, only one pressure detection component is needed to ensure detection accuracy, thereby reducing the cost of the scanning translation pen.

[0016] In one embodiment, the distance between the two support portions gradually decreases from the side closer to the front end of the housing to the side farther away from the front end of the housing, and the connecting portion is disposed on the side of the two support portions farther away from the front end of the housing.

[0017] The distance between the two support parts is relatively large on the side closer to the front end of the shell and relatively small on the side farther from the front end of the shell. The connecting part is located at the position where the distance between the two support parts is relatively small. Therefore, during the pressing process of the pen holder, it is beneficial for the connecting part to produce slight deformation.

[0018] In one embodiment, each of the support portions includes a connecting section and a pressing section for pressing, the pressing section being located on the side of the connecting section near the front end of the housing, and the connecting portion being disposed between the connecting sections of the two support portions.

[0019] In other words, both support sections can be used directly for pressing, meaning the pressing section can be pressed and slid on the scanned medium, such as paper.

[0020] In one embodiment, the dimension of the pressing segment along the thickness direction of the scanning translation pen is greater than the dimension of the connecting segment along the thickness direction of the scanning translation pen.

[0021] In other words, the thickness of the pressing section can be increased compared to the connecting section. This increases the strength of the pressing section and improves the reliability of its pressing action. Furthermore, a greater thickness for the pressing section compared to the connecting section results in less deformation, or even no deformation, during the pressing process. This allows the pressing section to more effectively transfer the reaction force exerted by the scanned medium on the pen tip holder to the connecting section and the connecting part, thus facilitating the pressure detection component's detection of minute deformations in the connecting part.

[0022] In one embodiment, the pen holder includes a pen head for pressing, the pen head being disposed between the two supports.

[0023] In other words, you can also press the pen tip, which is equivalent to pressing and sliding the pen tip on the paper or other scanning media.

[0024] In one embodiment, each of the support portions has a connecting section and an extension section. The extension section is located on the side of the connecting section near the front end of the housing. The dimension of the extension section along the thickness direction of the scanning translation pen is greater than the dimension of the connecting section along the thickness direction of the scanning translation pen. The pen head is disposed at the end of the extension section of the two support portions away from the connecting section. The connecting portion is disposed between the connecting sections of the two support portions.

[0025] The extension section is thicker than the connecting section, which increases the strength of the extension section. This reduces the deformation of the extension section during the pressing of the pen tip, or even prevents the extension section from deforming. As a result, the extension section can more effectively transfer the support force exerted by the scanned medium on the pen tip holder to the connecting section and the connecting part, which in turn facilitates the pressure detection component to detect the micro-deformation of the connecting part.

[0026] In one embodiment, a first stress groove is formed on the connecting portion, extending along the length direction of the scanning translation pen, and the pressure detection component is located at least at the detection portion of the first stress groove.

[0027] When the pen tip holder is pressed, a significant stress concentration can occur near the first stress groove. Therefore, by setting the first stress groove and placing the pressure detection component at least at the first stress groove, it is easier to detect the micro-deformation of the pen tip holder, thereby improving the detection effect.

[0028] In one embodiment, the first stress groove extends through the connecting portion along the thickness direction of the scanning translation pen.

[0029] In one embodiment, the connecting part includes a connecting body and two first crossbeams, the two first crossbeams being located on opposite sides of the connecting body along the width direction of the scanning translation pen, and the first stress groove being formed on the connecting body.

[0030] In other words, two first crossbeams can be used to support the connecting body, making it easier for the connecting body to produce micro-deformation.

[0031] In one embodiment, a portion of the connecting body is connected to the housing.

[0032] The connection between the main body and the shell facilitates the fixation of the pen tip holder and provides a fulcrum for the main body to undergo slight deformation during the pressing of the pen tip holder.

[0033] In one embodiment, the connecting body includes a second crossbeam, a connecting block, and two longitudinal beams. The two longitudinal beams are spaced apart along the width direction of the scanning translation pen. The second crossbeam and the connecting block are both disposed between the two longitudinal beams. The first stress groove is formed on the second crossbeam, and the connecting block is connected to the housing.

[0034] The second crossbeam and the connecting block are essentially two separate parts on the connecting body. The second crossbeam is used to generate micro-deformation, and the connecting block is used to connect with the shell. In this way, the part on the connecting body that connects to the shell can be better avoided affecting the part on the connecting body that generates micro-deformation.

[0035] In one embodiment, the second crossbeam is flush with the two first crossbeams; or, the second crossbeam is offset from the two first crossbeams along the length of the scanning translation pen.

[0036] Compared to the second crossbeam being flush with the two first crossbeams, the second crossbeam is offset from the two first crossbeams along the length of the scanning translation pen. This ensures that the second crossbeam is almost unaffected by the two first crossbeams during the pressing process of the pen head holder. Therefore, it is not necessary to increase the size of the second crossbeam along the length of the scanning translation pen, and the pressure detection component does not need to have more detection elements to ensure the detection accuracy of the pressure detection component.

[0037] In one embodiment, the two longitudinal beams extend toward the front end of the housing, and a second stress groove extending along the length of the scanning translation pen is formed between each longitudinal beam and the corresponding support portion. The connecting block or the second crossbeam is located at one end of the two longitudinal beams near the front end of the housing.

[0038] When the pen holder is pressed, significant stress concentration can also occur near the second stress groove. Therefore, when the connecting block or the second crossbeam is set on the front side of the two first crossbeams along the length of the scanning translation pen, the second stress groove can help the connecting body to produce micro-deformation.

[0039] In one embodiment, the second crossbeam is broken into two parts so that the break forms the first stress groove.

[0040] This means that the second crossbeam can be composed of two separate parts, which makes it easier for obvious micro-deformations to occur on the second crossbeam, thereby further improving the detection effect.

[0041] In one embodiment, the scanning translation pen includes an intermediate component disposed on the connecting portion, and the pressure detection component is bonded to the intermediate component.

[0042] Since the pen tip holder needs to be pressed and slid on the scanning medium such as paper, the entire pen tip holder is generally made of the same wear-resistant material for ease of manufacturing. However, the bonding performance of wear-resistant materials is usually poor, and it is difficult to reliably fix the pressure detection component to the connecting part by bonding, especially by high-temperature bonding. Therefore, an intermediate part with better bonding performance can be set on the connecting part, and the pressure detection component and the intermediate part can be bonded together by high-temperature tape or the like.

[0043] In one embodiment, a first stress groove is formed on the connecting portion extending along the length direction of the scanning translation pen, and the pressure detection component is located at least at the detection portion of the first stress groove;

[0044] The number of intermediate components is at least two, and at least one of the intermediate components is respectively provided on both sides of the first stress groove along the width direction of the scanning translation pen; or,

[0045] The intermediate component has a clearance groove that extends through the intermediate component. The intermediate component is disposed in the region of the connecting portion where the first stress groove is located, and the clearance groove avoids the first stress groove.

[0046] In one embodiment, the intermediate component is connected to the connecting portion; or, the intermediate component and the connecting portion are an integral structure.

[0047] In one embodiment, the pressure detection component includes a flexible circuit board electrically connected to the main circuit board, and the flexible circuit board is bonded to the intermediate component.

[0048] In one embodiment, the pressure detection assembly includes a flexible circuit board and at least two piezoresistive elements disposed on the flexible circuit board. The flexible circuit board is electrically connected to the main circuit board, and at least one of the piezoresistive elements is disposed on opposite sides of the first stress groove along the width direction of the scanning translation pen.

[0049] This application provides a scanning translation pen, which includes a housing, a pen tip holder, a pressure detection component, and a main circuit board. The pressure detection component, with at least a detection portion disposed on the pen tip holder, detects the deformation of the pen tip holder when it is pressed and outputs a detection signal. The main circuit board is electrically connected to the pressure detection component to receive the detection signal and control the scanning translation pen to activate its scanning function based on the detection signal. By placing the pressure detection component on the pen tip holder and utilizing the deformation of the pen tip holder to activate the scanning function, the scanning translation pen of this application embodiment has a relatively simple manufacturing process and relatively low cost, as it eliminates the need for grooves on the sidewall of the housing and for fixing aluminum blocks at the grooves.

Detailed Implementation

[0065] The principles and spirit of this application will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided merely to enable those skilled in the art to better understand and implement this application, and are not intended to limit the scope of this application in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art.

[0066] According to an embodiment of this application, a scanning translation pen is proposed.

[0067] In this article, it is important to understand that the terms "length direction," "front," and "back," etc., used to indicate orientation or positional relationships are based on the appendix. Figure 1 The orientation or positional relationship indicated by "thickness direction" etc. is based on the attached... Figure 2 The orientations or positional relationships shown are for illustrative purposes only and to simplify the description of the embodiments of this application. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. Furthermore, any number of elements in the drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0068] The principles and spirit of this application will be explained in detail below with reference to several representative embodiments.

[0069] First refer to Figures 1 to 11 The diagram shows a structural schematic of an exemplary scanning translation pen suitable for implementing the embodiments of this application.

[0070] The scanning translation pen includes a housing 10, a pen tip holder 20, a pressure detection assembly 30, and a main circuit board (not shown).

[0071] The pen tip holder 20 is located at the front end of the housing 10.

[0072] The pen tip holder 20 is used for pressing and sliding on the scanned medium, such as paper. The way the pen tip holder 20 is positioned at the front end of the housing 10 is not limited, as long as it can be pressed and slid on the scanned medium, such as paper.

[0073] For example, the pen tip holder 20 may have one part of its structure disposed inside the housing 10 and another part of its structure extending out of the housing 10 for pressing and sliding. The pen tip holder 20 may also be disposed outside the housing 10. For example, the pen tip holder 20 and the housing 10 may together form a space for accommodating other components of the scanning translation pen.

[0074] The pressure detection component 30 has at least one detection part disposed on the pen holder 20, so as to detect the deformation of the pen holder 20 when the pen holder 20 is pressed and output a detection signal.

[0075] The pressure detection component 30 may have only the detection part set on the pen tip holder 20, or a part of the area including the detection part set on the pen tip holder 20, or the entire pressure detection component 30 set on the pen tip holder 20.

[0076] The main circuit board is located inside the housing 10. The main circuit board is electrically connected to the pressure detection assembly 30 to receive detection signals and control the scanning translation pen to activate the scanning function based on the detection signals.

[0077] Specifically, during use, the pen tip holder 20 is pressed and slid on the paper or other medium being scanned. The medium being scanned exerts a reaction force on the pen tip holder 20 (the reaction force refers to the reaction force exerted by the medium being scanned on the pen tip holder 20). Under the action of the reaction force, the pen tip holder 20 will undergo a certain deformation. This deformation is relatively small and can be called micro-deformation. After the pressure detection component 30 installed on the pen tip holder 20 detects the micro-deformation, it will output a detection signal. The pressure detection component 30 transmits the detection signal to the main circuit board. After receiving the detection signal, the main circuit board can use the detection signal to control the scanning pen to open the scanning function.

[0078] In other words, the scanning translation pen of this application embodiment sets the pressure detection component 30 on the pen tip holder 20 and uses the deformation of the pen tip holder 20 to realize the scanning function. Since it is not necessary to open a groove on the side wall of the housing 10, nor is it necessary to fix an aluminum block in the groove, the process of the scanning translation pen of this application embodiment is relatively simple and the cost is relatively low.

[0079] In one embodiment, please refer to Figures 1 to 4 The housing 10 has a light-transmitting window 10a. The pen holder 20 includes a connecting part 21 and two support parts 22. The two support parts 22 are respectively disposed on opposite sides of the light-transmitting window 10a along the width direction of the scanning translation pen. The connecting part 21 is located between the two support parts 22 and avoids the light-transmitting window 10a. The pressure detection component 30 has at least a detection part disposed on the connecting part 21.

[0080] The light-transmitting window 10a is used for the user to observe the scanned object framed within it. The connection part 21 avoids the light-transmitting window 10a, meaning that the connection part 21 will not block the light-transmitting window 10a.

[0081] The connecting part 21 can be connected to the two supporting parts 22, or it can be integrally formed with the two supporting parts 22.

[0082] The pressure detection component 30 has at least a detection part located on the connecting part 21, which means that the detection part of the pressure detection component 30 is located between the two support parts 22, which is equivalent to the detection part of the pressure detection component 30 being located approximately in the middle of the scanning translation pen along the width direction.

[0083] In related technologies, for scanning translation pens with pressure detection components set on the sidewalls of the housing, in order to ensure detection accuracy, pressure detection components are generally set on the sidewalls of opposite sides of the housing along the width direction of the scanning translation pen. In other words, at least two pressure detection components are generally required on the housing, which will increase the cost of the scanning translation pen.

[0084] In this embodiment, the detection part of the pressure detection component 30 is set on the connecting part 21 between the two support parts 22. The detection part of the pressure detection component 30 is roughly located in the middle of the scanning translation pen along the width direction. Therefore, only one pressure detection component 30 is needed to ensure detection accuracy, thereby reducing the cost of the scanning translation pen.

[0085] It should be noted that in some embodiments, the pressure detection component 30 may also have at least the detection part disposed on the support portion 22.

[0086] In one embodiment, please refer to Figure 11The distance between the two support portions 22 gradually decreases from the side closer to the front end of the housing 10 to the side farther away from the front end of the housing 10. The connecting portion 21 can be located on the side of the two support portions 22 away from the front end of the housing 10. That is to say, the distance between the two support portions 22 is relatively large on the side closer to the front end of the housing 10 and relatively small on the side farther away from the front end of the housing 10. The connecting portion 21 is located at the position where the distance between the two support portions 22 is relatively small. Therefore, during the pressing process of the pen holder 20, it is beneficial for the connecting portion 21 to undergo slight deformation.

[0087] In one embodiment, please refer to Figures 3 to 5 Each support portion 22 may include a connecting section 221 and a pressing section 222 for pressing. The pressing section 222 is located on the side of the connecting section 221 near the front end of the housing 10, and the connecting portion 21 is disposed between the connecting sections 221 of the two support portions 22. That is, both support portions 22 can be directly used for pressing, i.e., the pressing section 222 can be pressed and slid on the scanned medium such as paper.

[0088] Further, please refer to Figures 3 to 5 The dimension of the pressing segment 222 along the thickness direction of the scanning translation pen can be larger than that of the connecting segment 221 along the thickness direction of the scanning translation pen. In other words, the thickness of the pressing segment 222 can be increased compared to the connecting segment 221. This increases the strength of the pressing segment 222 and improves the reliability of pressing. In addition, the greater thickness of the pressing segment 222 compared to the connecting segment 221 results in relatively smaller deformation of the pressing segment 222 during the pressing process, or even no deformation. Therefore, the pressing segment 222 can more effectively transmit the support force exerted by the scanned medium on the pen holder 20 to the connecting segment 221 and the connecting part 21, which in turn facilitates the pressure detection component 30 in detecting the micro-deformation of the connecting part 21.

[0089] In another embodiment, please refer to Figures 6 to 11 The pen holder 20 may also include a pen head 23 for pressing, which is disposed between the two support portions 22. That is, the pen head 23 can also be pressed, which is equivalent to the pen head 23 pressing and sliding on the scanned medium such as paper.

[0090] The pen head 23 can be connected to the two support parts 22, or it can be integrally formed with the two support parts 22.

[0091] Further, please refer to Figures 9 to 11Each support portion 22 may have a connecting section 221 and an extension section 223. The extension section 223 is located on the side of the connecting section 221 near the front end of the housing 10. The dimension of the extension section 223 along the thickness direction of the scanning translation pen may be larger than the dimension of the connecting section 221 along the thickness direction of the scanning translation pen. The pen head 23 is disposed at the end of the extension section 223 of the two support portions 22 away from the connecting section 221. The connecting portion 21 is disposed between the connecting sections 221 of the two support portions 22. That is, the thickness of the extension section 223 may be increased compared to the connecting section 221.

[0092] The thickness of the extension section 223 is greater than that of the connecting section 221, which can increase the strength of the extension section 223. This reduces the deformation of the extension section 223 during the pressing process of the pen tip 23, or even prevents the extension section 223 from deforming. As a result, the extension section 223 can more effectively transmit the support force exerted by the scanned medium on the pen tip holder 20 to the connecting section 221 and the connecting part 21, which in turn facilitates the pressure detection component 30 to detect the micro-deformation of the connecting part 21.

[0093] In some embodiments, please refer to Figure 7 and Figure 8 When the strength of the extension segment 223 meets the requirements, for example, when the material of the extension segment 223 has good strength, the dimension of the extension segment 223 along the thickness direction of the scanning translation pen can also be smaller than the dimension of the connecting segment 221 along the thickness direction of the scanning translation pen.

[0094] In one embodiment, please refer to Figure 4 and Figure 5 A first stress groove 21a extending along the length direction of the scanning translation pen is formed on the connecting part 21, and at least the detection part of the pressure detection component 30 is disposed at the first stress groove 21a.

[0095] Figure 4 and Figure 5 The first stress groove 21a shown in the figure penetrates the connecting portion 21 along the thickness direction of the scanning translation pen. In other embodiments, the first stress groove 21a may also be a groove-shaped structure with a bottom wall formed by a recess in a part of the upper region of the connecting portion 21.

[0096] The pressure detection component 30 is positioned at least at the first stress groove 21a, meaning that the detection part of the pressure detection component 30 can cover the first stress groove 21a or be located near the first stress groove 21a.

[0097] For example, please refer to Figure 3The pressure detection assembly 30 may include a flexible circuit board 31 and at least two piezoresistive elements 32 disposed on the flexible circuit board 31. The flexible circuit board 31 is electrically connected to the main circuit board, for example, the flexible circuit board 31 can be electrically connected to the main circuit board through a BTB (Board-to-board Connector). At least one piezoresistive element 32 may be disposed on each of the opposite sides of the first stress groove 21a along the width direction of the scanning translation pen.

[0098] The piezoresistive element 32 is used to detect the slight deformation of the connecting part 21. The piezoresistive element 32 is equivalent to the detection part of the pressure detection component 30. When the pen holder 20 is pressed, the piezoresistive element 32 converts the detected deformation of the connecting part 21 into a detection signal, which is then transmitted to the main circuit board via the flexible circuit board 31.

[0099] When the pen tip holder 20 is pressed, a significant stress concentration can occur near the first stress groove 21a. Therefore, by setting the first stress groove 21a and placing the pressure detection component 30 at least at the first stress groove 21a, it is easier to detect the micro-deformation of the pen tip holder 20, thereby improving the detection effect.

[0100] In one embodiment, please refer to Figures 2 to 5 The connecting part 21 may include a connecting body 211 and two first crossbeams 212. The two first crossbeams 212 are located on opposite sides of the connecting body 211 along the width direction of the scanning translation pen. A first stress groove 21a may be formed on the connecting body 211. That is, the two first crossbeams 212 can be used to support the connecting body 211, so that the connecting body 211 is more likely to produce micro-deformation.

[0101] Further, please refer to Figures 2 to 5 A portion of the connecting body 211 can also be connected to the housing 10, which facilitates the fixing of the pen holder 20 and provides a fulcrum for the connecting body 211 to generate slight deformation during the pressing process of the pen holder 20.

[0102] The connection body 211 can be connected to the housing 10 in any way. For example, the connection body 211 can be bonded, welded, or fastened to the housing 10 by fasteners such as screws or rivets.

[0103] In one embodiment, please refer to Figures 3 to 5The connecting body 211 may include a second crossbeam 2111, a connecting block 2112, and two longitudinal beams 2113. The two longitudinal beams 2113 are spaced apart along the width direction of the scanning translation pen. The second crossbeam 2111 and the connecting block 2112 are both disposed between the two longitudinal beams 2113. The second crossbeam 2111 is located on the side of the connecting block 2112 away from the front end of the housing 10. A first stress groove 21a is formed on the second crossbeam 2111. The connecting block 2112 is connected to the housing 10, for example, by welding it to a welding post at a corresponding position on the housing 10 through a through hole.

[0104] The second crossbeam 2111 and the connecting block 2112 can both be connected to the two longitudinal beams 2113, and the second crossbeam 2111 and the connecting block 2112 can also be integrally formed with the two longitudinal beams 2113.

[0105] The second crossbeam 2111 and the connecting block 2112 are essentially two separate parts on the connecting body 211. The second crossbeam 2111 is used to generate micro-deformation, and the connecting block 2112 is used to connect with the shell 10. Thus, the part on the connecting body 211 that connects to the shell 10 can be better avoided from affecting the part on the connecting body 211 that generates micro-deformation.

[0106] Please see Figure 4 and Figure 5 The second crossbeam 2111 can be broken into two parts so that the break forms a first stress groove 21a. This means that the second crossbeam 2111 can be composed of two separate parts. This makes it easier for obvious micro-deformation to occur on the second crossbeam 2111, thereby further improving the detection effect.

[0107] Please see Figure 4 and Figure 5 The second crossbeam 2111 can be flush with the two first crossbeams 212, which means that the second crossbeam 2111 and the two first crossbeams 212 are on a straight line.

[0108] Please see Figures 9 to 11 The second crossbeam 2111 can also be offset from the two first crossbeams 212 in the length direction of the scanning translation pen, that is, the second crossbeam 2111 is not flush with the two first crossbeams 212. Figures 9 to 11 The second crossbeam 2111 is located behind the two first crossbeams 212 along the length of the scanning translation pen. In other embodiments, the second crossbeam 2111 may also be located in front of the two first crossbeams 212 along the length of the scanning translation pen.

[0109] For the pen holder 20, which is flush with the two first beams 212, during the pressing process of the pen holder 20, the second beam 2111 will generate compressive and tensile strains in the length direction of the scanning translation pen due to the influence of the two first beams 212. In order to ensure detection accuracy, the size of the second beam 2111 along the length direction of the scanning translation pen cannot be too small. The pressure detection component 30 also needs to be equipped with more detection elements, such as piezoresistive elements 32, to detect the compressive and tensile strains respectively.

[0110] Regarding the pen holder 20, which is staggered from the two first crossbeams 212 along the length of the scanning translation pen, the second crossbeam 2111 is almost unaffected by the two first crossbeams 212 during the pressing process of the pen holder 20. Figures 9 to 11 The second crossbeam 2111, located behind the two first crossbeams 212 along the length of the scanning translation pen, mainly generates compressive strain and hardly generates tensile strain. Similarly, the second crossbeam 2111, located in front of the two first crossbeams 212 along the length of the scanning translation pen, mainly generates tensile strain and hardly generates compressive strain. Therefore, it is not necessary to increase the size of the second crossbeam 2111 along the length of the scanning translation pen, and the pressure detection component 30 does not need to be equipped with more detection elements to ensure the detection accuracy of the pressure detection component 30.

[0111] In one embodiment, please refer to Figures 3 to 5 The two longitudinal beams 2113 can extend towards the front end of the housing 10, and each longitudinal beam 2113 and the corresponding support 22 form a second stress groove 21b extending along the length direction of the scanning translation pen. Figures 3 to 5 The connecting block 2112 is located at one end of the two longitudinal beams 2113 near the front end of the housing 10, which is equivalent to the connecting block 2112 being located on the front side of the two first crossbeams 212 along the length direction of the scanning translation pen. In other embodiments, the second crossbeam 2111 may also be located at one end of the two longitudinal beams 2113 near the front end of the housing 10.

[0112] When the pen holder 20 is pressed, significant stress concentration can also occur near the second stress groove 21b. Therefore, when the connecting block 2112 or the second crossbeam 2111 is set on the front side of the two first crossbeams 212 along the length direction of the scanning translation pen, the second stress groove 21b can help the connecting body 211 to produce micro-deformation.

[0113] In one embodiment, please refer to Figure 2 and Figure 4The scanning translation pen can also have an intermediate part 40 set on the connecting part 21, and the pressure detection component 30 is bonded to the intermediate part 40. That is to say, the pressure detection component 30 can be fixed on the connecting part 21 by bonding it to the intermediate part 40.

[0114] The intermediate component 40 can be connected to the connecting part 21. For example, the intermediate component 40 can be welded to the connecting part 21, or fastened by fasteners such as screws and rivets. The intermediate component 40 and the connecting part 21 can also be an integral structure. For example, the intermediate component 40 and the connecting part 21 can be formed into an integral structure by injection molding.

[0115] Please see Figure 2 and Figure 4 For the connecting part 21 provided with the first stress groove 21a, the number of intermediate parts 40 can be at least two, and at least one intermediate part 40 is provided on each of the opposite sides of the first stress groove 21a along the width direction of the scanning translation pen.

[0116] In other embodiments, the intermediate member 40 may have a relief groove that extends through the intermediate member 40. The intermediate member 40 is disposed in the area of ​​the connecting portion 21 where the first stress groove 21a is located. The relief groove avoids the first stress groove 21a, which means that the relief groove will not block the first stress groove 21a.

[0117] Since the pen tip holder 20 needs to be pressed and slid on the scanning medium such as paper, the entire pen tip holder 20 is generally made of the same wear-resistant material for ease of manufacturing. However, the bonding performance of wear-resistant materials is usually poor, and the pressure detection component 30 is difficult to be firmly fixed to the connecting part 21 by bonding, especially by high temperature bonding. Therefore, an intermediate part 40 with better bonding performance, such as a steel sheet, can be set on the connecting part 21. The pressure detection component 30 and the intermediate part 40 can be bonded together using high temperature tape or the like.

[0118] For example, for a pressure detection assembly 30 provided with a flexible circuit board 31, the flexible circuit board 31 can be bonded to the intermediate part 40.

[0119] In some embodiments, the connecting part 21 may be made of a material with good adhesive properties, and the pressure detection component 30 may be bonded to the connecting part 21.

[0120] The use of the verbs "including" and "contains" and their inflections in the application documents does not preclude the existence of elements or steps other than those described in the application documents. The article "a" or "one" preceding an element does not preclude the existence of multiple such elements.
