Description

Technical Field

[0001] The present application relates to the technical field of smart devices, and in particular to a scanning pen. Background Art

[0002] The scanning pen is also called a dictionary pen, a translation pen, a portable scanner, etc. It is very popular among users because it is easy to carry, convenient for mobile office and study, and has functions such as translation, point reading, repeating, scanning, query, and storage.

[0003] However, in order to be easy to hold, the size of the existing scanning pen is usually small, so the display screen area on the scanning pen is also small, resulting in poor display effect of the display screen. Utility Model Content

DETAILED DESCRIPTION

[0079] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0080] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0081] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0082] The scanning pen is roughly rectangular in structure, and it can be considered that the scanning pen has a length direction, a width direction, and a thickness direction. For example, the direction where the long side is located can be the length direction of the scanning pen, and the direction where the short side is located can be the width direction of the scanning pen. For the convenience of explanation in the following embodiments, the X direction is used as the length direction of the scanning pen, the Y direction is used as the width direction of the scanning pen, and the Z direction is used as the thickness direction of the scanning pen. Of course, the scanning pen can also be set to a square or oval shape. The embodiments of the present application do not impose any special restrictions on the specific shape of the scanning pen.

[0083] When the user holds the scanning pen to scan, if the size of the scanning pen is too large, it will be difficult to hold the scanning pen, and the scanning pen may fall or slip out of the hand during the scanning process. If the size of the scanning pen is too small, the space for setting the display screen on the host is relatively small, resulting in poor display effects on the display screen, such as too small fonts and too low resolution.

[0084] In view of this, an embodiment of the present application provides a scanning pen that can take into account both display effect and ease of holding.

[0085] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0086] like Figure 1 , Figure 2As shown, the scanning pen mainly includes two parts: a main body 10 and a scanning component 20. The scanning component 20 is arranged at one end of the main body 10 along the length direction. Usually, a display screen 30 is arranged on the main body 10, and a scanning window 40 is arranged on the scanning component 20. The scanning window 40 is used to collect information to be scanned, and the collected information can be displayed on the display screen 30 in a preset form after being processed by the main board in the main body 10.

[0087] The scanning component 20 and the host 10 may be an integrated structure or a separate structure that is movably connected to each other. Figure 1 to Figure 4 The figure shows a schematic diagram of a structure in which the scanning component 20 and the host 10 are rotatably connected. In this structure, the scanning component 20 is rotatably connected to the host 10, and the scanning component 20 can rotate between a folded state and an unfolded state relative to the host 10. Figure 3 , Figure 4 As shown, the folded state is the state when the angle between the scanning component 20 and the host 10 is approximately 0°, that is, the state when the user is watching the display screen 30 and carrying it. The large display screen 30 can meet the user's use in various learning scenarios. At the same time, the simple appearance and compact size can meet the user's demand for portability. Figure 1 , Figure 2 As shown, the unfolded state is the state when the angle between the scanning component 20 and the host 10 is approximately 180°, that is, the product state when the scanning function is used. Of course, the unfolded scanning pen can also be used for video, text learning, audio and video entertainment and other experiences.

[0088] In addition to the above two usage states, the scanning component 20 can also include a support state between the folded state and the unfolded state, that is, the scanning component 20 can also be rotated to any angle between the folded state and the unfolded state, such as 30°, 45°, 60°, 90°, etc. At this time, when the scanning pen is placed on the desktop, the scanning component 20 can support the host 10, making it convenient for users to watch videos. The embodiment of the present application does not impose any special restrictions on the specific angle of the unfolded scanning pen.

[0089] Specifically, Figure 2 , Figure 3 and Figure 4As shown, the host 10 includes a first surface 101 and a second surface 102 that are arranged opposite to each other. The first surface 101 may be provided with a display screen 30, and the second surface 102 may be provided with a receiving groove 103. When the scanning component 20 is in the folded state, the scanning component 20 can be stored in the receiving groove 103. The provision of the receiving groove 103 allows the scanning component 20 to occupy no or less extra space outside the host 10 when it is in the folded state. The folded scanning component 20 may be flush with the second surface 102 to keep the shape of the scanning pen neat. Of course, the folded scanning component 20 may also be raised relative to the second surface 102, so that the user can open the scanning component 20 with his fingers. In addition, the receiving groove 103 may not be provided on the host 10, and when the scanning component 20 is in the folded state, the scanning component 20 may also be stacked outside the host 10.

[0090] The larger the width of the host 10, the larger the area of ​​the display screen 30 provided on the host 10. Figure 1 As shown, when the width of the host is greater than the width of the scanning component, the width of the display screen can be set to be greater than the width of the scanning component, thereby improving the user's visual experience.

[0091] When the scanning component 20 is in a folded state, the user can experience video or text learning, audio and video entertainment, etc. through the display screen 30. At the same time, the folded scanning pen is also convenient for the user to carry with him.

[0092] When the scanning component 20 is in the unfolded state, the user can hold the scanning pen to scan. In a possible holding method, as shown in FIG. Figure 5 As shown, the user can hold the host 10 part with his hand, then move the window close to and align it with the information to be scanned (such as information on paper), and then drag the host 10 with the scanning pen to drive the scanning component 20 to slide on the paper, so that the scanning window 40 completes the collection of the information on the paper. The collected information can be processed by the main board in the host 10 and displayed on the display screen 30 in a preset form. At this time, since the user's holding part is on the host 10, it can be avoided that the hand blocks the information on the paper during the scanning process, thereby causing an operation blind spot.

[0093] In addition, you can Figure 6 As shown, the user can hold the scanning component 20 of the scanning pen and slide it on the paper to scan and collect the information on the paper. At this time, since the hand is at the scanning component 20, the hand can avoid blocking the display screen 30, so that the user can observe the information on the display screen 30 while scanning.

[0094] In response to the above different holding methods, this application provides implementation solutions of various sizes, weights and related structures of the scanning pen, so that users can choose to adopt different implementation solutions under different scenario requirements.

[0095] It should be noted that the solutions in the following embodiments are applicable to both integrated scanning pens and foldable scanning pens. For the sake of ease of description, the following embodiments will be described using a foldable scanning pen as an example, and other forms of scanning pens can be considered similarly.

[0096] In order to facilitate the user to hold the host 10 for scanning, in one implementation, as Figure 7 As shown, the width D1 of the host 10 can be selected within the range of 20 mm to 100 mm, that is, 20 mm ≤ D1 ≤ 100 mm. Therefore, on the one hand, by setting the upper limit of the width of the host 10 to be less than or equal to 100 mm, the host 10 will not be inconvenient to hold by hand due to the large width; on the other hand, by setting the lower limit of the width of the host 10 to be greater than or equal to 20 mm, the host 10 will not have too small a space for setting the display screen 30 due to the small width. Therefore, while taking into account the convenience of holding, it is ensured that the display screen 30 has a large enough setting space.

[0097] Furthermore, the width D1 of the host 10 can be set within a range of 30 mm to 80 mm. That is, 30 mm ≤ D1 ≤ 80 mm. This range matches the holding range of the tiger's mouth of an average adult, making it more comfortable for adults to hold. Furthermore, considering that the hand holding range of minors is smaller, the design range of the width can be further narrowed, so that the width D1 of the host 10 can be set within a range of 30 mm to 55 mm, that is, 30 mm ≤ D1 ≤ 55 mm. Or the width D1 can be set within a range of 40 mm to 70 mm, that is, 40 mm ≤ D1 ≤ 70 mm. In this way, the comfort and convenience of minors holding the device is guaranteed, while taking into account the comfort and convenience of adults holding the device, and also ensuring that the display screen 30 has sufficient setting space.

[0098] When the user holds the host 10 to scan, if the holding position is too high from the paper, the stability during movement may be affected. The length of the scanning component 20 will affect the distance between the host 10 and the paper, so the length of the scanning component 20 can be set within a suitable range. In a possible implementation, Figure 7 As shown, the length L2 of the scanning component 20 can be set to be less than or equal to 40 mm. For example, it can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, etc. In this way, it can be ensured that the holding position is not too high from the paper surface, thereby improving the stability of holding the host 10 for scanning.

[0099] In addition, in order to make the size ratio of the scanning pen more coordinated, the length of the scanning component 20 can also be adjusted by selecting a suitable ratio based on the length of the host 10. Figure 7 As shown, the length L1 of the host 10 and the length L2 of the scanning component 20 may satisfy the following relationship: L2≤0.4×L1.

[0100] It should be noted that, while reducing the length of the scanning component 20, in order to ensure that the housing of the scanning component 20 has sufficient volume to accommodate its internal components, the thickness and width of the scanning component 20 can be appropriately increased. For example, the width of the scanning component 20 can be adjusted within a range less than or equal to the width of the host 10.

[0101] When the user holds the host 10 for scanning, the length L1 of the host 10 can be selected between 40 mm and 150 mm. When L1 is selected as 40 mm, the coverage length of the thumb and index finger when holding the host 10 can be guaranteed. When L1 is selected as 150 mm, it is convenient to hold and abut the host 10 with the base of the thumb.

[0102] like Figure 8 As shown, the host 10 includes a host 10 shell and a protective frame 104 arranged around the edge of the host 10 shell, the protective frame 104 includes a first side 1041 and a second side 1042 extending along the length direction, and the first side 1041 and the second side 1042 are provided with a protrusion 1043 at least at one end close to the scanning component 20. Among them, the protective frame 104 can provide certain protection for the host 10 to prevent the host 10 from being damaged due to falling or collision. On this basis, the protrusion 1043 is provided at the end of the first side 1041 and the second side 1042 of the protective frame 104 close to the scanning component 20, which can not only strengthen the protection of the corners of the host 10, but also use the protrusion 1043 to limit the user's holding position. Thereby, the user can hold the host 10 more stably for scanning, and prevent the hand from sliding down during the sliding scanning process.

[0103] Furthermore, in order to better limit the hand, the size of the protrusion 1043 can be designed more reasonably, for example, the protrusion 1043 has a preset length, width and thickness, so that the protrusion 1043 can form a more effective limit on the holding position.

[0104] It should be noted that the reference direction of the length, width and thickness of the protrusion 1043 is consistent with the reference direction of the length, width and thickness of the scanning pen.

[0105] Specifically, Fig. 9As shown, the length L3 of the protrusion 1043 can be set to be less than or equal to 0.5 times the length of the host 10. For example, L3 can be set to 0.1 times, 0.2 times, 0.3 times, 0.4 times, 0.5 times, etc., of the length of the host 10. When the length of the host 10 is 100 mm, the length L3 of the protrusion 1043 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, etc. The length L3 of the protrusion 1043 can be further set to 5 mm ≤ L3 ≤ 30 mm, thereby keeping the gripping part below the middle of the host 10, so that the gripping height is not too high, thereby improving the stability when holding the host 10 for scanning.

[0106] In addition, if Fig. 9 As shown, the width E of the protrusion 1043 can also be set to be less than or equal to 10mm, that is, the width E of the protrusion 1043 protrudes from the first side 1041 or the second side 1042 along the width direction Y of the host 10. For example, it can be selected as 0.25mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. If the width E of the protrusion 1043 is too large, it will occupy too much space and be inconvenient to carry, while if the width E of the protrusion 1043 is too small, it will not be able to form an effective limit to the hand. Therefore, the width E of the above-mentioned protrusion 1043 can be further selected to be in the range of 0.25mm to 3mm, thereby ensuring that the protrusion 1043 does not occupy too much space along the width direction, and the protrusion 1043 can also form an effective limit to the hand.

[0107] Furthermore, along the thickness direction of the host 10, the thickness of the protrusion 1043 can be set to be less than or equal to 20 mm. This can ensure the contact area between the protrusion 1043 and the user's hand, making the protrusion 1043 more effective in limiting the hand. Further, the thickness range of the protrusion 1043 can be selected to be 5 mm to 10 mm, thereby ensuring that the protrusion 1043 does not occupy too much space along the thickness direction, and can also make the protrusion 1043 effectively limit the hand.

[0108] like Fig. 9As shown, the raised portion 1043 has a first limiting surface 1043a, and the angle between the first limiting surface 1043a and the first side 1041 is θ, and θ satisfies: 90°≤θ<180°. The above-mentioned first limiting surface 1043a can be the end surface of the raised portion 1043 that contacts the user's hand when realizing the limiting function. If the angle θ is too small, a sharp angle will be formed, which may cause pain in the hand when contacting the hand. If the angle θ is too large, the hand is easy to slide down along the first limiting surface 1043a, so that the limiting effect is not obvious. Therefore, further, the range of θ can be selected as: 90°<θ<175°, and further, the range of θ can be selected as: 90°<θ<150°. Selecting the above range can not only ensure effective limiting of the hand, but also ensure the comfort of the hand when contacting the raised portion 1043.

[0109] It should be noted that one or more protrusions 1043 may be provided, and the size and location of the protrusions 1043 may be selected according to actual needs. For example, when the scanning pen is used and carried in daily life, the corners of the host 10 are more likely to collide, and the collision force at the corners is greater. Therefore, in order to strengthen the protection of the corners of the host 10, protrusions 1043 may be provided at the corners of the protective frame 104.

[0110] like Fig.10 , Fig.11 As shown, when the four corners of the protective frame 104 are provided with the raised portions 1043, when the folded host 10 is held with one hand or both hands, the raised portions 1043 at the four corners can be used to limit the hands, thereby improving the stability of the user when viewing the screen.

[0111] In order to make the protective frame 104 have good buffering and protective effects, the toughness of the protective frame 104 can be greater than the toughness of the shell of the host 10. Therefore, when the host 10 falls or bumps, the protective frame 104 can form a buffer force on the collision part, thereby ensuring that the shell of the host 10 and the internal components are not damaged.

[0112] Since the protective frame 104 and the housing of the host 10 are made of different materials, the protective frame 104 and the housing of the host 10 can be made separately and then assembled. The protective frame 104 and the housing of the host 10 can also be injection molded into an integral structure using an injection molding process. For example, a two-color injection molding process or a beer-injection process can be used.

[0113] In order to hold the host 10 more comfortably, in a possible implementation, as Fig.12 , Fig.13 As shown in FIG. 1 , the width of the main unit 10 is partially narrowed to form a converging portion 105. Fig.14As shown, when the user holds the host 10, the user can hold it at the convergence part 105 of the host 10. Since the convergence part 105 is narrower than other parts of the host 10, the opening of the thumb can be reduced when holding it, making it easier and more comfortable to hold the host 10 for scanning operations, and the scanning pen has a good grip feel.

[0114] Specifically, Fig.13 As shown, the width D3 of the converging portion 105 can be set to a range of 20 mm to 79 mm. Alternatively, the difference between the width D1 of the host 10 and the width D3 of the converging portion 105 can be set to a range of 1 mm to 10 mm. When the width D3 of the converging portion 105 is too large, the improvement in comfort is small. When the width D3 of the converging portion 105 is too small, the size of the display screen 30 may be limited. Therefore, when the width D3 of the converging portion 105 is set to the above range, a good grip can be ensured, and a sufficiently large setting space can be reserved for the display screen 30.

[0115] In order to ensure that when the user holds the closing portion 105 of the host 10, the closing portion 105 has enough space for the fingers to hold, such as Fig.13 As shown, the length L4 of the constricted portion 105 can be set to a range of 10 mm to 60 mm along the length direction of the host 10. Thus, it can be ensured that the constricted portion 105 has enough length space to accommodate a finger.

[0116] like Fig.12 , Fig.13 As shown, the main unit 10 includes a first side wall 106 and a second side wall 107 extending along the length direction. The above-mentioned concave portion 105 may include a first concave surface 1051 located on the first side wall 106, and a second concave surface 1052 located on the second side wall 107. The first concave surface 1051 and the second concave surface 1052 correspond to each other in the width direction of the main unit 10, so that the first concave surface 1051 and the second concave surface 1052 together constitute the concave portion 105.

[0117] like Fig.12 , Fig.13 , Fig.14 As shown, at least part of the scanning component 20 in this solution is embedded in one end of the host 10. Fig.12 It can be seen from the figure that the appearance of the scanning pen can be made similar to that of a mobile phone. Since the scanning component 20 is embedded in the host 10, the overall appearance of the host 10 is less affected.

[0118] Specifically, Fig.12 , Fig.13As shown, the host 10 includes a first surface 101 and a second surface 102 that are arranged opposite to each other, and the first surface 101 is provided with a display screen 30. The scanning component 20 includes a transparent observation window 201 arranged on the first surface 101 and a scanning window 40 arranged on the second surface 102. The transparent observation window 201 is located outside the display screen 30, and at least a portion of the scanning window 40 overlaps with the display screen 30 in the thickness direction of the host 10. In this embodiment, the scanning window 40 and the display screen 30 are separately arranged on the first surface 101 and the second surface 102 of the host 10, which makes full use of the space and does not interfere with each other. On the one hand, a larger display screen 30 can be arranged on the first surface 101, so that more content can be displayed, and the user's experience is improved. In addition, the transparent observation window 201 can be made of transparent material, so that it can be used to observe the scanned object, so that the user can operate the scanning pen more accurately for scanning. On the other hand, the scanning window 40 on the second surface 102 has a sufficiently large setting space, so that a scanning image with a larger field of view can be captured through a larger window, thereby improving the scanning efficiency.

[0119] In addition, if Fig.12 , Fig.13 , Fig.14 As shown, the scanning assembly 20 may further include an abutment portion 202, which protrudes from the host 10. Specifically, the abutment portion 202 may include two supporting protrusions, which may be arranged on both sides of the scanning window 40 along the width direction. Thus, when the user operates the scanning pen to slide and scan on the scanning object, the protruding abutment portion 202 may be supported between the host 10 and the scanning object, thereby reducing the friction during the sliding scanning, making the user's operation more labor-saving and preventing the end surface of the host 10 from being worn during the scanning process.

[0120] In order to further improve the grip feel of the user when holding the host 10, a curved surface structure can be formed on the shell of the host 10, so that the surface of the mobile phone shell is more rounded as a whole, fits better with the palm, and has a better grip feel.

[0121] Specifically, Fig.15 As shown, the outer surface of at least one of the first side wall 106 and the second side wall 107 of the host 10 can be set to a first convex surface structure. The first convex surface is a curved surface that bulges outward and has a smooth surface. Compared with a flat structure, the convex surface structure has a higher fit with the palm and a better grip feel.

[0122] In a possible implementation, the first convex surface may be a first cylinder, and the generatrix of the first cylinder extends along the length direction of the host 10. Thus, the bending direction of the first convex surface is more matched with the bending direction of the base of the hand when holding, thereby further improving the grip feel.

[0123] Optionally, the thickness of the first convex surface may be in the range of 5 mm to 15 mm along the thickness direction of the host 10. When the thickness of the first convex surface is too small, the fit between the first convex surface and the palm is low, and when the thickness of the first convex surface is too large, the space occupied by the first convex surface is large, so selecting the thickness range of the first convex surface to be 5 mm to 15 mm can ensure the fit between the first convex surface and the palm, and avoid the first convex surface from occupying too much space.

[0124] like Fig.16 As shown, the host 10 further includes a third side wall 108 and a fourth side wall 109 extending along the width direction of the host 10, and the outer surface of at least one of the third side wall 108 and the fourth side wall 109 can be set as a second convex surface. Fig.14 As shown, when the user's fingers hold the contraction portion 105, the palm or the base of the thumb may contact the third side wall 108. At this time, the second convex surface fits the palm more closely and has no sharp edges and corners, so the grip is better. And when the first side wall 106, the second side wall 107, the third side wall 108 and the fourth side wall 109 are all set as convex surface structures, the overall structure of the host 10 can be made more consistent. Specifically, the second convex surface can also be a second cylinder, and the generatrix of the second cylinder extends along the width direction of the host 10, so as to further improve the grip.

[0125] When using Figure 6 When the scanning assembly 20 is held for scanning in the manner shown, the length of the scanning assembly 20 can be set to be greater than 40 mm, so that there is enough holding space when holding the scanning assembly 20.

[0126] In addition, the length of the scanning component 20 can also be designed with reference to the length of the host 10, for example, Fig.17 As shown, the length of the scanning component 20 can be set to be greater than or equal to half the length of the host 10, and less than the length of the host 10. That is, 0.5×L1≤L2<L1. In this way, the storage convenience and the holding convenience can be balanced.

[0127] When holding the scanning component 20, the width of the scanning component 20 is also a factor that affects the holding stability. In one implementation, the width of the scanning component 20 and the width of the host 10 can be designed to satisfy the following relationship: 15% ≤ (D2 / D1) ≤ 95%, so that the width of the scanning component 20 is smaller than the width of the host 10, so that the scanning component 20 is easier to hold relative to the host 10. In another implementation, the above range can be further selected as: 15% ≤ (D2 / D1) ≤ 78%, thereby further reducing the width range of the scanning component 20, and further reflecting the structure of a large screen and a small width of the scanning component 20, so as to balance the display effect and the convenience of holding. In addition, the above range can be further selected as: 40%≤(D2 / D1)≤72%, and further selected as 57%≤(D2 / D1)≤62%; thus, on the premise of ensuring that the screen is large and the width of the scanning component 20 is small to balance the display effect and the convenience of holding, the ratio difference between the scanning component 20 and the host 10 is not too large, thereby avoiding the difficulty in holding due to the large difference in volume and size between the host 10 and the scanning component 20, further improving the convenience of holding, and allowing minors with less grip strength to easily hold and scan.

[0128] In the above embodiment, the width range of the scanning component 20 is limited by the ratio of the width of the scanning component 20 to the width of the host 10. When it comes to the numerical range, the following ranges can be selected in sequence: For example, the width D2 of the scanning component 20 satisfies: 15mm≤D2≤95mm; further, the width D2 of the scanning component 20 satisfies: 19mm≤D2≤80mm; this range can adapt to the size of the tiger's mouth of ordinary people and has good grip convenience and comfort, and can ensure that the scanning component 20 has a sufficiently large scanning window 40 to achieve multi-line scanning. Further, the width D2 of the scanning component 20 satisfies: 19mm≤D2≤55mm; this range can adapt to the size of the tiger's mouth of both adults and minors, for example, the width D2 can be selected as 19mm, 20mm, 25mm, 29mm, 30mm, 31mm, 35mm, 40mm, 45mm, 50mm, 55mm, etc.

[0129] The ratio of the weight W1 of the host 10 to the weight W2 of the scanning component 20 can be roughly in the range of 1≤W1:W2≤10. In order to prevent the host 10 from tipping over during scanning due to excessive weight, the weight difference between the host 10 and the scanning component 20 can be reduced. For example, W1 and W2 can satisfy 1≤W1:W2≤4. This can prevent tipping over during scanning due to top-heaviness and also facilitate holding by users with weak grip strength.

[0130] The center of gravity of the scanning pen can be set on the host 10 or the scanning component 20. When the center of gravity of the scanning pen is located on the host 10, as shown in FIG. Fig.17 As shown, the host 10 has a first end face B and a first center line C, wherein the first end face B is the end face of the host 10 close to the scanning component 20, and the first center line C is the center line of the host 10 in the length direction, and the center of gravity W of the scanning pen can be set between the first end face B and the first center line C. Therefore, when in use, the center of gravity W can be located below the first center line C of the host 10, thereby improving the top-heavy problem.

[0131] Furthermore, if Fig.17 As shown, along the length direction, let the distance from the first end surface B to the first center line C be H1, and let the distance from the first end surface B to the center of gravity W of the scanning pen be H2, then H1 and H2 satisfy: H2: H1≤2 / 3. In this way, the position of the center of gravity W of the scanning pen can be further limited to a lower position. Furthermore, H1 and H2 satisfy: H2: H1≤1 / 2. In this way, it is equivalent to setting the position of the center of gravity W of the scanning pen within a quarter of the lower end of the host 10. This can further improve the problem of heavy feet and light weight, and more effectively prevent the scanning pen from tipping over during the scanning process.

[0132] It should be noted that, in order to adjust the center of gravity of the scanning pen, on the one hand, it can be achieved by adjusting the outer shell material of the host 10 or the outer shell material of the scanning component 20. On the other hand, it can also be achieved by adjusting the distribution of the internal components of the host 10 and the internal components of the scanning component 20. For example, in order to make the center of gravity of the scanning pen located on the scanning component 20, a heavier component can be arranged in the scanning component 20, such as a battery can be arranged in the scanning component 20.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
