Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to scanning components and scanning pens. Background Technology

[0002] The scanning pen uses scanning technology to scan and recognize text content, and then uses its built-in dictionary and translation software to perform functions such as text parsing, translation, and reading.

[0003] Currently, barcode scanners typically house the detection element on the casing, and the user activates the scanning function by pressing the casing while holding the scanner. Specifically, related technologies mainly employ a pressure sensor located on the side wall of the casing. Pressing the casing causes deformation, and the pressure sensor detects this deformation to determine whether to activate the scanning function. However, during use, when the scanner is held but the scanning function is not required, the casing is highly susceptible to accidental triggering of the scanning function due to pressure. Summary of the Invention

The pressure detection element is located in the scanning housing and mounted on the scanning bracket. A gap exists between the portion of the scanning bracket that supports the pressure detection element and the inner wall surface of the scanning housing, thus creating a gap between the pressure detection element and the inner wall surface of the scanning housing. In this application, by mounting the pressure detection element on the scanning bracket and utilizing the contact between the scanning part and the object being scanned to deform the scanning bracket and activate the scanning function, and by creating a gap between the scanning bracket and the inner wall surface of the scanning housing, the impact of force on the pressure detection element from the scanning housing can be minimized. Compared to related technologies where the pressure detection element is placed on the side wall of the scanning housing and force needs to be applied to the scanning housing to trigger it, the scanning component and scanning pen of this application will not trigger the scanning function by force transmitted to the pressure detection element even when the scanning pen is held normally and the scanning function is not performed. This can effectively avoid the situation of accidentally activating the scanning function, reduce the risk of accidental triggering, and thus improve the user experience. Attached Figure Description

Detailed Implementation

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] In this invention, the terms "upper," "lower," "front," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0061] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0062] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0063] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0064] As described in the background section, related technologies typically place pressure sensors on the side walls of the housing. Pressing the housing causes deformation, and the pressure sensor detects this deformation to determine whether to activate the scanning function. However, in this method, the user must manually press both sides of the housing to activate the scanning function after the pen is in contact with the object being scanned. This is inconvenient for the user. Furthermore, in scenarios where the user is holding the pen to view the scanned content or where scanning is not required, the housing is prone to accidentally triggering the scanning function due to pressure. This not only increases the pen's power consumption but also significantly impacts the user experience.

[0065] To address the issue of accidental triggering of the scanning function, related technologies typically incorporate an anti-accidental touch module. This module, using a processor, touch sensors, and other components, effectively determines whether a press on the scanning pen is accidental, thus initiating the scanning function. However, this approach is costly, complex to assemble, and difficult to implement in scanning pens.

[0066] Based on this, this application provides a scanning component and a scanning pen, in which a pressure detection element is mounted on the scanning bracket. The scanning function is activated by the deformation of the scanning bracket in contact with the object being scanned. A gap is maintained between the scanning bracket and the inner wall of the scanning housing, minimizing the impact of force on the pressure detection element caused by the scanning housing. Compared to related technologies where the pressure detection element is mounted on the side wall of the scanning housing and requires force to trigger, the scanning component and pen of this application prevent the scanning function from being triggered by force transmitted to the pressure detection element, even when the scanning pen is held normally without performing the scanning function. This effectively avoids accidental activation of the scanning function, reduces the risk of accidental triggering, and thus improves the user experience.

[0067] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0068] Please see Figures 1 to 4 This application provides a scanning assembly 100, which includes a scanning housing 10, a scanning bracket 20, and a pressure detection element 30. The scanning bracket 20 is installed inside the scanning housing 10 and has a scanning section 22a that extends out of the scanning housing 10 to contact the object being scanned. The pressure detection element 30 is located in the scanning housing 10 and mounted on the scanning bracket 20. A gap 10a exists between the portion of the scanning bracket 20 that carries the pressure detection element 30 and the inner wall surface of the scanning housing 10, ensuring a gap 10a between the pressure detection element 30 and the inner wall surface of the scanning housing 10. The pressure detection element 30 is configured to detect the deformation of the scanning section 22a and output a detection signal to the main board. The main board controls the scanning assembly 100 to start the scanning function based on the detection signal.

[0069] The scanning pen 1 of this application has a scanning component 100 that activates the scanning function by placing a pressure detection element 30 on the scanning bracket 20 and using the scanning part 22a to contact the object being scanned to deform the scanning bracket 20. A gap 10a is maintained between the scanning bracket 20 and the inner wall of the scanning housing 10, minimizing the impact of force on the pressure detection element 30 from the scanning housing 10. Compared to related technologies where the pressure detection element 30 is placed on the side wall of the scanning housing 10 and requires force to trigger, the scanning component 100 of this application prevents the scanning function from being triggered by force transmitted to the pressure detection element 30 even when the device is held normally and the scanning function is not being used. This effectively avoids accidental activation of the scanning function, reduces the risk of accidental triggering, and improves the user experience.

[0070] Optionally, the pressure sensing element 30 may include a flexible circuit board 31 and a piezoresistive element 32 disposed on the flexible circuit board. In the embodiments of this application, the edges of the flexible circuit board 31 are designed with rounded corners, which can disperse stress and prevent the piezoresistive element 32 from tearing due to force transmission at the edges, thereby causing the pressure sensing element 30 to fail.

[0071] In one possible embodiment, the flexible circuit board 31 has at least four piezoresistive elements 32, such as R1, R2, R3, R4, etc. R1 and R2 form a voltage divider circuit, and R3 and R4 form a voltage divider circuit. When the resistance of R1 and R4 decreases, the voltage of the voltage divider circuit formed by R1 and R2 increases, and the voltage of the voltage divider circuit formed by R3 and R4 decreases. The change in output force can be calculated based on the changes in these two sets of voltages.

[0072] In some embodiments, the scanning housing 10 includes a main housing 11 and a front housing 12. The front housing 12 is connected to one end of the main housing 11 along its length. The scanning bracket 20 is mounted on the main housing 11, and the scanning part 22a extends out of the front housing 12. The portion of the scanning bracket 20 that carries the pressure detection element 30 has a gap 10a between it and the inner wall surfaces of the main housing 11 and the front housing 12. In this way, the main housing 11 can be used to fix part of the scanning bracket 20, and the scanning bracket 20 can extend into the front housing 12 with a gap 10a, which is more conducive to the installation of the scanning bracket 20 and makes the overall assembly process of the scanning assembly 100 more reasonable.

[0073] Furthermore, the main housing 11 includes a first housing 111 and a second housing 112. The first housing 111 covers the second housing 112 to form a receiving space 13. Both the first housing 111 and the second housing 112 are connected to the front housing 12. The scanning bracket 20 is located in the receiving space 13 and is installed on the second housing 112. Specifically, the scanning bracket 20 is fixed on the second housing 112, and then the first housing 111 is used to cover the second housing 112.

[0074] When the scanning unit 22a contacts the object being scanned and is pressed to perform scanning, the scanning bracket 20 deforms, which is sensed by the pressure detection element 30, thereby triggering the scanning function. That is, the scanning function requires the pressure detection element 30 to detect the deformation of the scanning bracket 20. Therefore, to avoid the situation where the scanning function is mistakenly triggered due to deformation of the scanning bracket 20 caused by force on the scanning housing 10 without any scanning action, and to ensure the scanning bracket 20 is fixed, it is sufficient to maintain a gap 10a between a portion of the scanning bracket 20 and the inner wall surface of the scanning housing 10. Based on this, in some embodiments, see... Figure 4 The scanning bracket 20 also has a mounting portion 21 and a deformable portion 22. The mounting portion 21 is mounted on the scanning housing 10, and the deformable portion 22 is connected to the mounting portion 21 and extends along the length of the scanning housing 10. A gap 10a is formed between the deformable portion 22 and the inner wall surface of the scanning housing 10, and the deformable portion 22 extends at least partially out of the scanning housing 10 to form a scanning portion 22a. The pressure sensing element 30 is disposed on the deformable portion 22 and extends from the deformable portion 22, at least partially located on the mounting portion 21. In this way, the scanning bracket 20 can be fixed to the scanning housing 10 by the mounting portion 21, and the gap 10a is formed between the deformable portion 22 and the inner wall surface of the scanning housing 10. That is, even when part of the structure of the scanning bracket 20 (the deformable portion 22) is suspended inside the scanning housing 10, the scanning bracket 20 can still be effectively fixed. When the scanning assembly 100 falls or is impacted, the displacement of the scanning bracket 20 due to the overall suspension of the scanning bracket 20 can be effectively avoided, thereby affecting the realization of the scanning function.

[0075] It should be noted that the mounting part 21 of the scanning bracket 20 is located approximately in the main housing 11, the deformable part 22 extends approximately into the front housing 12, and there is a gap 10a between it and the inner wall surface of the front housing 12.

[0076] Optionally, see Figure 5 and Figure 6 The deformable portion 22 includes a first surface 221 and a second surface 222 facing away from each other. The first surface 221 is inclined from the connection point with the mounting portion 21 in a direction away from the mounting portion 21, so that the first surface 221 is perpendicular to the length direction of the scanning housing 10 (e.g., ...). Figure 6 The first angle α is formed by the X direction (in the middle), and the pressure detection element 30 is disposed on the second surface 222. It can be understood that the deformation part 22 is inclined relative to the bottom surface of the scanning housing 10, that is, the distance between the deformation part 22 and the bottom surface of the scanning housing 10 gradually increases from the connection point with the mounting part 21 in the direction away from the mounting part 21. In this way, when the scanning part 22a contacts the object being scanned for scanning, the deformation part 22 is inclined relative to the scanning housing 10, so that the scanning bracket 20 is easier to deform regardless of the tilt angle held by the user, the force applied by the user will be reduced, and it will be more convenient for the user to use.

[0077] Furthermore, the deformation part 22 will deform toward the second surface 222 when subjected to force during scanning. Therefore, by placing the pressure detection element 30 on the second surface 222, it is easier to detect the deformation of the scanning bracket 20, and the pressure recognition will be more sensitive, thereby making the activation of the scanning function more sensitive.

[0078] It should be noted that at least a portion of the sensing part of the pressure sensing element 30 is disposed on the deformation part 22, so as to detect the deformation of the scanning bracket 20 and output a detection signal when the scanning part 22a is pressed. Exemplarily, the pressure sensing element 30 may have its sensing part disposed on the deformation part 22, or a portion of the pressure sensing element 30 including the sensing part may be disposed on the deformation part 22, or the entire pressure sensing element 30 may be disposed on the deformation part 22.

[0079] In some embodiments, a mounting groove 223 is provided on the second surface 222. Along the length of the scanning housing 10, the mounting groove 223 extends from the deformable portion 22 to the mounting portion 21, and the pressure detection element 30 is disposed in the mounting groove 223. Compared to directly placing the pressure detection element 30 on the second surface 222, by providing a mounting groove 223 on the second surface 222 and placing the pressure detection element 30 in the mounting groove 223, on the one hand, the mounting groove 223 can protect the pressure detection element 30, preventing the outer periphery of the pressure detection element 30 from being easily displaced, damaged, or even falling off due to force. On the other hand, by providing a mounting groove 223 on the second surface 222, the thickness of the deformable portion 22 can be reduced, which is more conducive to the deformation of the scanning bracket 20, thereby making the pressure detection element 30 more sensitive to force detection. Furthermore, by extending the mounting groove 223 from the deformable portion 22 to the mounting portion 21, the pressure detection element 30 can be mounted on the scanning bracket 20 over a larger area, which is beneficial to the stability of the pressure detection element 30 installation.

[0080] Furthermore, the mounting groove 223 is provided with a stress groove 224 extending along the width direction of the scanning housing 10. The stress groove 224 is located in the deformation part 22, and the sensing part of the pressure detection element 30 is set corresponding to the stress groove 224. By setting the stress groove 224, when the scanning part 22a is subjected to force, the stress can be concentrated near the stress groove 224, where the stress change is the greatest. By setting the sensing part of the pressure detection element 30 corresponding to the stress groove 224, the pressure detection element 30 can more sensitively detect the deformation of the scanning bracket 20, thereby improving the detection effect of the pressure detection element 30.

[0081] Optionally, the bottom surface of the mounting groove 223 is formed as an inclined surface 223a, which is inclined from the deformable portion 22 towards the mounting portion 21, so that the thickness of the scanning bracket 20 gradually decreases from the deformable portion 22 towards the mounting portion 21. That is, the mounting groove 223 is also inclined relative to the scanning housing 10, and the inclination direction is consistent with the inclination direction of the first surface 221 of the deformable portion 22. In this way, the structural layout of the scanning bracket 20 can be made more reasonable, and the deformation of the deformable portion 22 is more favorable while ensuring the reliable strength of the scanning bracket 20.

[0082] Furthermore, the inclined surface 223a forms a second angle β with the length direction of the scanning housing 10, and the second angle β is the same as the first angle α. In this way, the inclined surface 223a of the mounting groove 223 has the same inclination angle as the first surface 221 of the deformable part 22, so that the thickness of the deformable part 22 is approximately the same from the connection with the mounting part 21 towards the scanning part 22a, which is more conducive to the deformation of the deformable part 22.

[0083] Optionally, the first angle α and the second angle β can be acute angles, which can ensure the strength of the deformable part 22 while allowing a gap 10a between the deformable part 22 and the bottom surface of the scanning housing 10.

[0084] It is worth noting that the scanning housing 10 is provided with a scanning port 10b. As mentioned above, the scanning housing 10 may include a main housing 11 and a front housing 12. Specifically, the scanning port 10b is located on the side of the front housing 12 facing the object being scanned. The scanning port 10b has the aforementioned scanning portion 22a on both opposite sides along the width direction of the scanning assembly 100. That is, the size of the scanning portion 22a in the width direction of the scanning assembly 100 affects the size of the scanning port 10b. Based on this, in some embodiments, the deformable portion 22 may include a scanning portion 22a and a connecting portion 22b. The connecting portion 22b connects the mounting portion 21 and the scanning portion 22a, and the pressure detection element 30 is provided on the connecting portion 22b and extends to the mounting portion 21. Along the width direction of the scanning housing 10, the width of the scanning portion 22a is less than or equal to the width of the connecting portion 22b. Preferably, the width of the scanning part 22a is smaller than the width of the connecting part 22b, so that the scanning part 22a occupies less space along the width direction of the scanning housing 10, thereby making the range of the scanning port 10b larger. This allows the scanning assembly 100 to scan more content, which is beneficial to expanding the scanning range of the scanning assembly 100.

[0085] During normal use, the angle between the scanning component 100 and the object being scanned is typically 45°-90°, for example, it can be 50°, 55°, 70°, 65°, 80°, 80°, 85°, etc. Preferably, see [reference needed]. Figure 7 The scanning effect of the scanning component 100 is best at an angle of 75°.

[0086] It should be noted that the limiting angles used by the scanning component 100 are 45° and 90°. If the angle between the scanning component 100 and the scanned object is less than 45°, please refer to [the relevant documentation]. Figure 8 If the distance between the scanning port 10b of the scanning component 100 and the object being scanned is too small, the information on the object will not be able to be identified in a timely manner. If the angle between the scanning component 100 and the object being scanned is greater than 90°, see [reference needed]. Figure 9 If the distance between the scanning port 10b of the scanning component 100 and the object being scanned is too large, the information on the object being scanned will not be able to be identified in a timely manner.

[0087] In some implementations, the scanning component 100 is configured such that as the angle between it and the object being scanned gradually increases, the trigger threshold of the pressure detection element 30 also gradually increases. That is, when the scanning component 100 is held and used by the user, the closer the angle between the scanning component 100 and the object being scanned becomes to a perpendicular position, the greater the pressure exerted by the scanning component 100 on the scanning support 20. Therefore, this pressure also affects the triggering of the pressure detection element 30. This allows for more reasonable control of the scanning function of the scanning component 100.

[0088] It should also be noted that the angle between the scanning component 100 and the object being scanned should be interpreted in a broad sense. That is, the object being scanned is not limited to a plane. In practice, it also includes situations where the object being scanned can be a discontinuous plane or a surface with unevenness.

[0089] Optionally, the trigger threshold of the pressure detection element 30 ranges from 30g to 250g. By limiting this trigger threshold range, it is easier for the user to initiate the scanning function when holding the scanning component 100 in contact with the object being scanned, resulting in more accurate and sensitive scanning and recognition. If the trigger threshold of the pressure detection element 30 is too small or too large, it will be difficult for the user to easily initiate the scanning function.

[0090] For example, see Figures 7 to 9 When the angle between the scanning component 100 and the object being scanned is approximately 45° (e.g., Figure 8 As shown), the trigger threshold of the pressure detection element 30 can range from 30g to 120g, for example, the trigger threshold can be 60g, 75g, 90g, etc. When the angle formed between the scanning component 100 and the scanned object is approximately 75° (e.g., ... Figure 7 As shown), the trigger threshold of the pressure detection element 30 can range from 120g to 180g, for example, the trigger threshold can be 135g, 155g, 165g, etc. When the angle formed between the scanning component 100 and the scanned object is approximately 90° (e.g., ... Figure 9 As shown, the trigger threshold of the pressure detection element 30 can be in the range of 180g to 250g, for example, the trigger threshold can be 195g, 215g, 235g, etc.

[0091] During the use of the scanning assembly 100, if the contact force between the scanning unit 22a and the scanned object is too large, or if the scanning unit 22a is subjected to a large external force due to accidents such as collisions or drops, the deformation of the scanning bracket 20 will be too large, which can easily cause the pressure detection element 30 to fail. To limit the deformation of the scanning bracket 20, in some embodiments, see... Figure 10 and Figure 11The scanning assembly 100 may further include a limiting member 40 disposed within the scanning housing 10. The scanning bracket 20 is connected to the limiting member 40, and the pressure sensing element 30 is located between the scanning bracket 20 and the limiting member 40. Along the length direction and / or thickness direction of the scanning housing 10, a deformation gap 50 is provided between the limiting member 40 and the scanning bracket 20. The deformation gap 50 is configured to limit the deformation range of the scanning bracket 20. Thus, when the scanning unit 22a contacts the object being scanned and causes a large deformation of the scanning bracket 20, the limiting member 40 prevents the scanning bracket 20 from continuing to deform, thereby avoiding the failure of the pressure sensing element 30 due to excessive deformation of the scanning bracket 20. Furthermore, even if the scanning assembly 100 falls and the scanning unit 22a impacts the ground, the deformation of the scanning bracket 20 remains within a controllable range, providing a certain degree of protection for the pressure sensing element 30, thereby extending the service life of the scanning assembly 100.

[0092] In some embodiments, see Figure 10 and Figure 11 The limiting member 40 includes a main body 41 and a first limiting part 42. The main body 41 is connected to the scanning bracket 20, and a deformation gap 50 is formed between the first limiting part 42 and the scanning part 22a. In this way, based on the fixing of the limiting member 40 by connecting the main body 41 to the scanning bracket 20, the deformation gap 50 can be formed by the interval between the first limiting part 42 and the scanning part 22a, making the structural design of the limiting member 40 more reasonable.

[0093] It is understandable that the deformation gap 50 is formed between the scanning bracket 20 and the limiting member 40 near the scanning part 22a. In this way, the distance between the end of the scanning part 22a extending out of the scanning part 22a and the deformation gap 50 is shortened. After the scanning part 22a undergoes a large deformation due to a large force, it can quickly come into contact with the first limiting member 42, thereby reducing the further transmission of the force on the scanning part 22a. This can effectively control the deformation of the scanning bracket 20, thereby improving the limiting effect of the limiting member 40 on the scanning bracket 20.

[0094] Optionally, the deformation gap 50 can be 0.1mm-0.2mm, for example, 0.13mm, 0.15mm, 0.17mm, etc.

[0095] In one possible embodiment, in order to reduce the risk of pressure detection element 30 failing due to excessive deformation of scanning bracket 20, the material of scanning bracket 20 can be a flexible metal material such as stainless steel or copper alloy. The specific material is not limited in the embodiments of this application.

[0096] As described above, the second surface 222 of the deformable portion 22 is provided with a mounting groove 223. That is, the side of the deformable portion 22 facing the bottom surface of the scanning housing 10 is provided with a mounting groove 223, and the pressure detection element 30 is disposed in the mounting groove 223. In one example, the limiting member 40 may not be based on the mounting groove 223, but may be directly disposed above the scanning bracket 20, with the pressure detection element 30 disposed on the scanning bracket 20 and located between the limiting member 40 and the scanning bracket 20. In another example, the limiting member 40 may be based on the mounting groove 223, with the limiting member 40 covering the mounting groove 223, and the pressure detection element 30 disposed in the mounting groove 223.

[0097] The following explanation uses the setting of the limiting member 40 based on the mounting slot 223 as an example.

[0098] Specifically, the main body 41 covers the mounting groove 223 to define the pressure sensing element 30 within the mounting groove 223. The mounting groove 223 has a side wall surface 223b along its length, and the side of the scanning part 22a connected to the side wall surface 223b is a third surface 221a, see [reference]. Figure 11 The deformation gap 50 includes a first deformation gap 51 and a second deformation gap 52. The first deformation gap 51 is formed between the first limiting part 42 and the side wall surface 223b, and is configured to limit the deformation range of the deformation part 22 along the length direction of the scanning housing 10. The second deformation gap 52 is also formed between the first limiting part 42 and the third surface 221a, and is configured to limit the deformation range of the deformation part 22 along the thickness direction of the scanning housing 10. Thus, by utilizing the side wall surface 223b of the mounting groove 223 and the third surface 221a of the scanning part 22a with the first limiting part 42 of the limiting member 40 to form the above-mentioned deformation gap 50, the structure of the scanning part 22a and the mounting groove 223 can be fully utilized without the need for additional limiting structures. This simplifies the overall structure of the scanning assembly 100 and makes the internal spatial layout of the scanning assembly 100 more reasonable.

[0099] Furthermore, the first deformation gap 51 and the second deformation gap 52 can limit the scanning component 100 in two directions respectively, which can further control the deformation of the scanning bracket 20, thereby improving the safety of the pressure detection element 30.

[0100] Specifically, during the scanning process of the scanning component 100 moving on the object being scanned, if a large force is applied to the scanning component 100, or if the scanning component 100 falls and contacts the ground with the scanning part 22a, the deformation of the scanning bracket 20 increases. When the deformation of the scanning bracket 20 along the length direction of the scanning housing 10 exceeds the first deformation gap 51, the side wall surface 223b of the mounting groove 223 will abut against the first limiting part 42; when the deformation of the scanning bracket 20 along the thickness direction of the scanning housing 10 exceeds the second deformation gap 52, the third surface 221a of the scanning part 22a will abut against the first limiting part 42. In this way, the situation where the pressure detection element 30 fails due to excessive deformation of the scanning bracket 20 in both directions can be prevented.

[0101] It is also understandable that part of the structure of the main body 41 is located in the mounting groove 223. This allows the limiting member 40 and the scanning bracket 20 to occupy less space in the thickness direction of the scanning housing 10, which is beneficial for controlling the thickness of the scanning assembly 100.

[0102] It should be noted that, in addition to the side wall surface 223b, the mounting groove 223 also has a first inner wall surface 223c opposite to the side wall surface 223b and a second inner wall surface 223d located between the two. Thus, the mounting groove 223 not only has an opening facing the second surface 222, but also an opening opposite to the second inner wall surface 223d. Furthermore, at least one of the side wall surface 223b and the first inner wall surface 223c is inclined, so that the opening of the mounting groove 223 gradually increases in the direction from the bottom of the mounting groove 223 towards the second surface 222, which is more conducive to the installation of the pressure sensing element 30.

[0103] In some embodiments, see Figure 10 The main body 41 has a first connecting hole 411, the mounting part 21 has a second connecting hole 211, and the scanning housing 10 has an open connecting post 10c. The first connecting hole 411, the second connecting hole 211, and the connecting post 10c are used for the same fastener 60 to pass through, so that the limiting member 40 and the scanning bracket 20 are connected to the scanning housing 10 by the fastener 60. Specifically, the fastener 60 passes through the first connecting hole 411 and the second connecting hole 211 in sequence and is then inserted into the connecting post 10c to achieve a fixed connection between the limiting member 40, the scanning bracket 20, and the scanning housing 10.

[0104] Optionally, the aforementioned first connecting hole 411 includes two holes. One first connecting hole 411 is located near the first limiting part 42 and adjacent to the inner wall surface of the scanning housing 10, while the other first connecting hole 411 is located away from the first limiting part 42 and spaced apart from the inner wall surface of the scanning housing 10. Correspondingly, the second connecting hole 211 and the connecting post 10c also each include two holes, each corresponding to one of the two first connecting holes 411. This makes the connection between the limiting member 40, the scanning bracket 20, and the scanning housing 10 more stable, and the layout is also more reasonable.

[0105] Furthermore, the main body 41 is provided with a second limiting part 43 at the first connecting hole 411, and the mounting part 21 is provided with a third limiting part 212 at the second connecting hole 211. The second limiting part 43 is connected to the third limiting part 212 to limit the position of the limiting member 40 relative to the scanning bracket 20 in the length direction of the scanning housing 10. Specifically, the second limiting part 43 is provided at the first connecting hole 411 near the first limiting part 42. By providing the second limiting part 43 connected to the third limiting part 212, the position of the limiting member 40 relative to the scanning bracket 20 in the length direction of the scanning housing 10 is limited, thereby improving the reliability of the connection between the two.

[0106] In addition, by placing the second limiting part 43 at the first connecting hole 411, the space around the first connecting hole 411 can be fully utilized without the need for additional limiting parts. This achieves both the connecting and limiting functions, and makes the spatial layout of the scanning component 100 more reasonable.

[0107] Optionally, the fastener 60 can be a screw, pin, bolt, or other similar structure.

[0108] In one example, the second limiting part 43 is a limiting groove recessed on the main body part 41, and the second limiting part 43 is located on the outer periphery of the first connecting hole 411. The third limiting part 212 is a limiting protrusion protruding on the mounting part 21, and the third limiting part 212 is circumferentially disposed on the outer periphery of the second connecting hole 211. By using the cooperation of the limiting groove and the limiting protrusion, it can be achieved simply by using the recess or protrusion of the first connecting hole 411 and the second connecting hole 211, which is simple in structure and easy to install and cooperate.

[0109] In another example, the second limiting part 43 is a limiting protrusion protruding from the main body part 41, and the third limiting part 212 is a limiting groove recessed from the mounting part 21, which can also achieve the limiting effect.

[0110] Typically, positioning posts are placed around the connecting hole for positioning. However, in this application, for the first connecting hole 411 near the first limiting part 42, the corresponding second connecting hole 211 is located near the scanning part 22a. Due to its proximity to the inner wall of the scanning housing 10, the space is limited. If the positioning posts are placed independently around the first connecting hole 411 as is conventional, it would inevitably occupy the space of the mounting part 21 of the scanning bracket 20, increasing the volume of the scanning bracket 20. This would both occupy the internal space of the scanning housing 10 and reduce the scanning range. Therefore, a positioning protrusion is provided at the bottom of the second connecting hole 211, and a positioning groove is provided at the top of the connecting post 10c. The positioning protrusion and the positioning groove cooperate to limit the position of the second connecting hole 211 relative to the connecting post 10c. By using the end positions of the first connecting hole 411 and the connecting post 10c to set the positioning structure, no additional space is occupied in the mounting part 21 of the scanning bracket 20, making the overall layout more reasonable.

[0111] In some possible embodiments, the scanning assembly 100 further includes a reinforcing member 70, which can be separately disposed from the scanning bracket 20. The reinforcing member 70 has a groove on the side facing the scanning bracket 20, and the scanning bracket 20 has a protrusion on the side facing the reinforcing member 70. The groove and protrusion cooperate to limit the position of the reinforcing member 70 relative to the scanning bracket 20. A pressure sensing element 30 is disposed on the side of the reinforcing member 70 facing away from the scanning bracket 20. Specifically, an adhesive layer is applied to the scanning bracket 20, and the groove and protrusion are used to position the reinforcing member 70, which can improve the assembly efficiency of the reinforcing member 70. Furthermore, both the reinforcing member 70 and the scanning bracket 20 are provided with stress grooves 224.

[0112] It is understandable that the surface flatness of the scanning bracket 20 may be insufficient due to process limitations after molding, resulting in unstable connection between the pressure sensing element 30 and the scanning bracket 20. Therefore, a reinforcing member 70 is provided on the scanning bracket 20 to improve the flatness of the surface used to mount the pressure sensing element 30. Optionally, the reinforcing member 70 can be an aluminum alloy plate / sheet or a stainless steel plate / sheet, etc.

[0113] It is understood that the reinforcing member 70 is directly mounted on the scanning bracket 20. In one example, the reinforcing member 70 can be based on the mounting groove 223 and mounted in the mounting groove 223. Specifically, the side of the reinforcing member 70 facing the inclined surface 223a of the mounting groove 223 has a groove 71, and the inclined surface 223a of the mounting groove 223 has a protrusion (not marked). The groove 71 and the protrusion cooperate to limit the position of the reinforcing member 70 relative to the mounting groove 223.

[0114] In some other possible embodiments, the reinforcing member 70 may also be integrally formed with the scanning housing 10, thereby simplifying the assembly process of the scanning bracket 20.

[0115] In some embodiments, the scanning assembly 100 further includes a rolling element 80, which is rotatably connected to the scanning section 22a, and at least a portion of the rolling element 80 extends outside the scanning housing 10. The rolling element 80 is configured to roll and contact the object being scanned during scanning. Rolling elements 80 are provided on both sides of the scanning housing 10. Specifically, the rolling elements 80 are located on both sides of the front housing 12. Compared to related technologies where both sides of the rolling element 80 are housings and the rolling element 80 is sandwiched within them, the present application's method does not occupy excessive space at the front end of the front housing 12, allowing for a larger scanning port 10b and thus expanding the scanning range of the scanning assembly 100. When the scanning assembly 100 scans, the rolling element 80 converts the sliding friction between the scanning section 22a and the object being scanned into rolling friction, thereby reducing the friction between the scanning assembly 100 and the object being scanned. This reduces wear on the scanning assembly 100 and improves user convenience.

[0116] Optionally, the rolling element 80 can be a rolling structure such as a roller or ball.

[0117] This application embodiment also provides a scanning pen 1, which includes a host 200 and the scanning component 100 of the scanning pen 1 described above, with the scanning component 100 connected to one end of the host 200.

[0118] The scanning pen 1 in this embodiment may have the same or similar beneficial effects as the scanning component 100 in the above embodiments. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0119] In some embodiments, the scanning component 100 is movably connected to the host 200, and the scanning component 100 has at least a retracted state and an unfolded state, see [reference]. Figure 12 In the storage state, the scanning component 100 is stored within the host unit 200. See also Figure 13 In the unfolded state, the scanning component 100 is unfolded relative to the host 200. It is understood that the scanning component 100 and the host 200 can be slidably connected or rotated. When the scanning function is needed, the host 200 is switched to the unfolded state; when not needed, the scanning component 100 remains in the retracted state, making the scanning pen 1 more versatile and easier for users to carry. Of course, in other embodiments, see... Figure 14 The scanning component 100 of the scanning pen 1 can be fixedly connected to the host 200, and can also achieve the beneficial effects of the scanning component 100 mentioned above.

[0120] The scanning components and scanning pen of the scanning pen disclosed in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the scanning components and scanning pen of this application and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
