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] A scanning pen is a learning tool that can realize functions such as point reading, rereading, and following reading. Currently, scanning pens are mostly designed in a simple straight strip shape, that is, they include a long strip pen shell, a pen head is set at the front end of the pen shell (i.e., one end in the length direction), a scanning module is set in the pen head, and it is used as a scanning part, and a display screen is set on the front of the pen shell. When using it, the user mainly holds the scanning pen so that the pen head abuts against the scanned object (such as a book, a picture on the desktop, etc.) to scan, and finally displays it on the display screen, so that the user can view the scanned content through the display screen.

[0003] However, in the related art, the display area of ​​the display screen of the scanning pen is very limited, which is not conducive to user viewing. If the width of the scanning pen body is directly widened to increase the display area, the user will need to use more force to clamp the scanning pen when holding it, which is not only inconvenient but also very tiring to use, and is not convenient for long-term use. Summary of the invention

[0004] In response to the above technical problems, the purpose of this application is to provide a scanning pen that can, on the basis of taking into account the expansion of the width of the host and the display screen, further solve the problem of reduced user adaptability caused by the expansion of the width of the host and the display screen when holding the pen with one hand.

[0005] Based on this, in a first aspect, the present application discloses a scanning pen, the scanning pen comprising:

[0006] A host, wherein the host is provided with a display screen, and a width b1 of the host satisfies: 20 mm ≤ b1 ≤ 100 mm; and

[0007] A scanning component, the scanning component comprising a scanning housing and a scanning module disposed in the scanning housing, the scanning housing being connected to one end of the host along the length direction;

[0008] In the width direction of the host, the width b2 of the scanning housing satisfies: 0.15b1≤b2≤0.95b1, and the scanning housing has a certain length in the length direction of the host so that the scanning housing can be held;

[0009] Among them, along the length direction of the host, the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell is less than or equal to 2 / 3 of the length of the host, or the ratio of the overall weight of the scanning component to the overall weight of the host is greater than or equal to a preset threshold.

[0010] In a second aspect, the present application further discloses a scanning pen, the scanning pen comprising:

[0011] A host, wherein the host is provided with a display screen, and a width b1 of the host satisfies: 20 mm ≤ b1 ≤ 100 mm; and

[0012] A scanning component, the scanning component comprising a scanning housing and a scanning module disposed in the scanning housing, the scanning housing being connected to one end of the host along the length direction;

[0013] In the width direction of the host, the width b2 of the scanning housing is smaller than the width b1 of the host, and the width b2 of the scanning housing satisfies: 19mm≤b2≤80mm, and the scanning housing has a certain length in the length direction of the host so that the scanning housing can be held;

[0014] Among them, along the length direction of the host, the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell is less than or equal to 2 / 3 of the length of the host, or the ratio of the overall weight of the scanning component to the overall weight of the host is greater than or equal to a preset threshold.

[0015] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0016] The scanning pen disclosed in the present application satisfies the following conditions by setting the host to have a width b1: 20mm≤b1≤100mm, which is much larger than the pen body width of conventional scanning pens on the market. Therefore, the display screen set on the host can be selected to be larger in size, thereby increasing the display area of ​​the host and facilitating user viewing. On this basis, the present application further considers that the ratio of the width of the scanning shell of the scanning component to the width of the host is 0.15b1≤b2≤0.95b1, that is, under the premise that the width of the host is increased, the width of the scanning shell is smaller than the width of the host. At the same time, it is further limited that the scanning shell of the scanning component has a certain length in the length direction of the host, so that the scanning shell can be held by the user. Therefore, child users can choose to hold on the scanning shell whose width is smaller than that of the host, while adult users can choose to hold on the host or on the scanning shell according to actual conditions. Therefore, the present application can, on the basis of taking into account the expansion of the width size of the host and the display screen, further solve the problem of reduced user adaptability of holding with one hand (for example, child users cannot hold or cannot hold for a long time) caused by the expansion of the width size of the host and the display screen.

[0017] On the basis that the width of the above-mentioned host is increased and the scanning shell has a certain length for holding, considering that if it is held on the scanning shell, that is, compared with holding it on the host, holding it on the scanning shell is equivalent to holding it at the front end of the scanning pen, if the scanning component is too light, when the user holds it, due to the weight of the scanning pen itself, the scanning pen as a whole will tip over to the end of the host away from the scanning component. Based on this, the present application also takes the weight of the scanning component and the host into consideration, by limiting the ratio of the overall weight of the scanning component to the weight of the host to be greater than or equal to a preset threshold, or making the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell less than or equal to 2 / 3 of the length of the host, that is, avoiding the center of gravity of the scanning pen being located at the end of the host (that is, away from the end of the scanning component), so that the center of gravity of the scanning pen is shifted as much as possible to the end where the host is connected to the scanning component, thereby avoiding the problem of top-heavy tipping when the user holds it on the scanning shell.

[0062] 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.

[0063] In this application, the terms "first", "second, third, fourth", 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.

[0064] As the applicant explained in the background technology, in related designs, the scanning pen is usually a straight-plate design, and the user usually holds the scanning pen on the body. Therefore, the body of the scanning pen will not be made too wide, otherwise the user, especially the child user will not be able to hold it or will not be able to hold it for a long time, resulting in the display screen width of the scanning pen cannot be made too large, the display content is limited, and the user's viewing experience is affected.

[0065] Specifically, if Figure 1As shown, the user usually holds the scanning pen in the following manner: the pen housing 3000 of the scanning pen is pressed against the base 1001 between the thumb 1000 and the index finger 2000, and then the pen housing 3000 of the scanning pen is clamped by the thumb 1000 and the index finger 2000. Therefore, the width of the scanning pen on the market cannot be too large, otherwise the user, especially the child user (the main user of the scanning pen), will not be able to hold it. If the width of the scanning pen is too large, the thumb 1000 and the index finger 2000 will be stretched apart, which will cause the thumb 1000 and the index finger 2000 to use more force to clamp the scanning pen, which is not only inconvenient but also tiring to use. At the same time, since children have smaller hands, the distance between the base of the thumb and the desktop is smaller when using the pen, and the child may hold the pen at the front end (i.e., close to the pen tip) when using it. If the center of gravity of the pen is relatively far back (i.e., the center of gravity is focused on the end of the pen shell), with the base of the thumb of the child's hand as the fulcrum, the torque in the direction of the center of gravity of the pen will be greater, requiring the child's hand to apply greater force to clamp the scanning part, which is not only inconvenient but also tiring to use for a long time. Due to this limitation, the width of the pen cannot be increased, so that the width of the screen 3001 of the pen is relatively narrow, resulting in limited display content. For example, the content of a scan needs to be displayed in pages to be displayed, or it can be displayed on one page, but the displayed font is very small, which is not conducive to user viewing.

[0066] Based on this, the present application discloses a scanning pen, which includes a main body and a scanning component. Among them, a display screen is provided on the main body, and the main body is roughly in the shape of a long flat plate, that is, the main body has a length direction, a width direction and a thickness direction. Along the width direction of the main body, the width b1 of the main body satisfies: 20mm≤b1≤100mm. The scanning component includes a scanning shell and a scanning module provided in the scanning shell, and the scanning module is used to scan the scanned object and display it on the display screen. The scanning shell is connected to one end of the main body along the length direction, and the width b2 of the scanning shell satisfies: 0.15b1≤b2≤0.95b1, and the scanning shell has a certain length in the length direction of the main body so that the scanning shell can be held.

[0067] The scanning pen disclosed in the present application satisfies the following conditions: 20 mm ≤ b1 ≤ 100 mm, so that the host has enough space to set a display screen with a larger display area. On this basis, considering the gripping problem of the user (especially the child user) holding the scanning pen (see the gripping method above), Figure 1), the present application first considers the width ratio between the scanning shell of the scanning component and the host, that is, the width of the scanning shell is b2 satisfying: 0.15b1≤b2≤0.95b1, so that the width of the scanning shell is smaller than the width of the host. Then, it is considered that the scanning shell of the scanning component has a certain length in the length direction of the host, so that the scanning shell can be held by the user. In this way, for children, who have a smaller width of the tiger's mouth, they can choose to hold it on the scanning shell, while for adult users, because their tiger's mouth is wider, they can choose to hold it on the scanning shell, or because the host also has a certain length, they can also choose to hold it on the host, that is, the scanning pen of the present application can adapt to different users. In other words, the scanning pen of the present application can solve the problem that the display screen of the scanning pen in the related art is too small, but directly widening the display screen of the scanning pen will bring inconvenience in holding and reduce user adaptability (for example, the tiger's mouth of children is too small to hold or cannot be held for a long time).

[0068] On the basis that the screen of the above-mentioned host is enlarged and the scanning shell has a certain length for holding, it is considered that if holding on the scanning shell, that is, compared with holding on the host, holding on the scanning shell is equivalent to holding on the front end of the scanning pen, if the scanning component is too light and the center of gravity of the scanning pen is close to the side of the host away from the scanning shell, when the user holds it, especially when a child user holds it, with the child user's hand base as the fulcrum, the torque in the direction of the center of gravity of the scanning pen will be greater, and the child user's hand needs to apply greater force to clamp the scanning pen, which is not only inconvenient but also very tiring to use, and is not convenient for long-term use; if a greater force is not used to clamp the scanning pen, the scanning pen as a whole will move away from the scanning component to the host. Based on this, the present application also takes the weight of the scanning component and the host into consideration, by limiting the overall weight of the scanning component to the weight of the host to be greater than or equal to a preset threshold, or by making the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell less than or equal to 2 / 3 of the length of the host, that is, avoiding the center of gravity of the scanning pen being located at the end of the host (that is, away from the end of the scanning component), so that the center of gravity of the scanning pen is shifted as much as possible to the end where the host is connected to the scanning component, reducing the torque of the scanning pen in the direction of the center of gravity, thereby avoiding the problem of top-heavy tilting caused by the user holding the scanning shell or requiring greater force to clamp the scanning shell, resulting in a poor holding experience.

[0069] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0070] Embodiment 1

[0071] This application embodiment provides a scanning pen 01. Please refer to Figure 2 and Figure 3 , Figure 2is a schematic diagram of the structure of the scanning pen disclosed in this application, Figure 3 1 is a schematic diagram of the scanning pen of the present application for a user to hold on the scanning housing. Specifically, the scanning pen 01 includes a host 10 and a scanning component 20. The host 10 may have a length direction X, a width direction Y, and a thickness direction. For the convenience of explanation in the following embodiments, the X direction is taken as the length direction X of the host 10, the Y direction is taken as the width direction Y of the host 10, and the Z direction is taken as the thickness direction of the host 10 ( Figure 4 ). For example, the outline of the host 10 may be a rectangle, the direction of the long side may be the length direction X of the host 10, and the direction of the short side may be the width direction Y of the host 10. Of course, the host 10 may also be set to an elliptical or oval shape, as long as it has a sufficient width to set a display screen 30 with a larger display area. The embodiment of the present application does not impose any special restrictions on the specific shape of the host 10.

[0072] Specifically, the host 10 is provided with a display screen 30. Along the width direction Y of the host 10, the host 10 has a width b1, and the width b1 satisfies 20 mm ≤ b1 ≤ 100 mm. The scanning component 20 includes a scanning housing 21 and a scanning module 23 ( Figure 2 The scanning module 23 is only shown in a dotted frame, and the dotted frame does not limit the specific shape and structure of the scanning module 23. The scanning module 23 is used to scan the scanned object and display the scanning result on the display screen 30. The scanning housing 21 is connected to one end of the host 10 along the length direction X. The scanning housing 21 has a width b2 in the width direction Y of the host 10, and b2 satisfies 0.15b1≤b2≤0.95b1. The scanning housing 21 has a certain length in the length direction X of the host 10 so that the scanning housing 21 can be held (such as Figure 3 As shown, Figure 3 The user's thumb and index finger can both hold the scanning housing 21).

[0073] The scanning pen 01 of the present application sets the host 10 to have a width b1 that satisfies: 20mm≤b1≤100mm, so that the display screen 30 set on the host 10 can be selected to be larger in size, thereby increasing the display area of ​​the host 10, which is convenient for users to watch. On this basis, the present application further considers that the width b2 of the scanning housing 21 of the scanning component 20 satisfies: 0.15b1≤b2≤0.95b1, that is, under the premise that the width of the host 10 is increased, the width of the scanning housing 21 is still smaller than the width of the host 10, and at the same time, it is further limited that the scanning housing 21 of the scanning component 20 has a certain length in the length direction X of the host 10, so that the scanning housing 21 can be held by the user. Therefore, child users can choose to hold the device on the scanning shell 21 whose width is smaller than that of the host 10, while adult users can choose to hold the device on the host 10 or on the scanning shell 21 according to actual conditions. In this way, while taking into account the expansion of the width of the host 10 and the display screen 30, the problem of reduced user adaptability of holding the device with one hand due to the expansion of the width of the host 10 and the display screen 30 (for example, child users cannot hold the device or cannot hold it for a long time) is further solved.

[0074] In other words, the scanning pen 01 of the present application is intended to solve the problem of user adaptability to holding the scanning pen with one hand caused by expanding the display screen width of the host 10 as much as possible. Specifically, the scanning shell 21 is set to have a certain length, and there is space for the user to hold it in the length direction X. At the same time, the width of the scanning shell 21 is smaller than the width of the host 10, so that the width of the scanning shell 21 can be adapted to or close to the width of the pen body of the scanning pen 01 in the related technology. Therefore, while expanding the width of the host 10 and the display screen 30 to achieve a large-area display, the problem of the adaptability of the scanning pen 01 to be held is solved.

[0075] It is understandable that, generally speaking, the width b1 of the host 10 is usually uniformly set, but the width of the host 10 is allowed to vary slightly. For example, there may be a few concave-convex structures on the host 10, and the concave-convex structures have little effect on the overall width of the host 10. For example, if it is a protruding design, the protruding position is approximately protruding within 0-5mm compared to other positions of the host 10, and it can be considered that the width of the host 10 is roughly uniform at this time.

[0076] In addition, the width of the host 10 may also be unevenly set. When the width of the host 10 is unevenly set, the width b1 mentioned above refers to the maximum width of the host 10 .

[0077] In some embodiments, the width b1 of the host 10 can be further set to satisfy: 30mm≤b1≤80mm, or further, can satisfy 40mm≤b1≤70mm, so that the width b1 of the host 10 is appropriate, and the width b1 of the host 10 is not too large while having a sufficient display area, so that for users who are accustomed to holding the host 10 (such as adult users with a small size of the tiger's mouth), the tiger's mouth will not be stretched too wide, avoiding the problem of being unable to hold for a long time due to the tiger's mouth being stretched too wide. Exemplarily, the width b1 of the host 10 can be set to 35mm, 40mm, 42mm, 45mm, 48mm, 50mm, 52mm, 55mm, 60mm, 62mm, 65mm, 70mm, 75mm, etc. The width b1 of the host 10 breaks through the pen body width of the scanning pen 01 in the related art (generally 28mm-33mm), so that while effectively taking into account the sufficient display area, it can also better adapt to the user's grip, and the user experience is better.

[0078] Furthermore, the width b1 of the host can also satisfy: 50mm<b1≤70mm, that is, the width b1 of the host 10 of the present application can be further limited to between 50mm and 70mm, so that the width of the host 10 is much larger than the width of the pen body of the scanning pen 01 on the market, so that it can have sufficient area to set up the display screen, thereby increasing the display area.

[0079] In some embodiments, the width b2 of the scanning shell 21 can be set to satisfy: 19mm≤b2≤80mm. Combined with the design that the width b2 of the scanning shell 21 is 0.15-0.95 of the width b1 of the host 10, on the one hand, the width of the scanning shell 21 is appropriate. On the basis of meeting the focusing scanning requirements of the scanning module 23 arranged in the scanning shell 21, the scanning range of the scanning module 23 can also be increased. Increasing the scanning range can enable the scanning module 23 to scan more content, for example, multi-line scanning can be achieved; on the other hand, the width of the scanning shell 21 is smaller than the width of the host 10. When the user (especially a child user) holds the scanning shell 21, it can avoid the problem of the tiger's mouth being stretched too wide, which leads to the problem of soreness of the tiger's mouth due to long-term use.

[0080] Furthermore, the width b2 of the scanning shell 21 also satisfies: 0.15b1≤b2≤0.78b1, that is, the width b2 of the scanning shell 21 is further smaller than the width b1 of the host 10, so that the width b2 of the scanning shell 21 can be closer to or more adapted to the pen body width of the scanning pen 01 in the related technology, which is further convenient for users with small hands (such as children or adult users with smaller thumb and index finger sizes) to hold, and has better user adaptability.

[0081] Exemplarily, the width b2 of the scanning housing 21 may be 0.18b1, 0.2b1, 0.25b1, 0.3b1, 0.35b1, 0.4b1, 0.45b1, 0.5b1, 0.55b1, 0.6b1, 0.65b1, 0.7b1, 0.75b1 or 0.78b1, etc. Further, the ratio of the width b2 of the scanning housing 21 to the width b1 of the host 10 may be further limited to 0.4-0.72, so that the width b2 of the scanning housing 21 is closer to or more suitable for the pen body width of the scanning pen 01 in the related art, so as to provide a better holding experience.

[0082] In some embodiments, the width b2 of the scanning shell 21 satisfies: 19mm≤b2≤80mm. Based on this, the width b2 of the scanning shell 21 can be further set to satisfy 19mm≤b2≤55mm, so that the width of the scanning shell 21 is more appropriate. While taking into account the scanning focus and expansion of the scanning range of the scanning module 23, the problem of affecting the user's grip due to the excessive width of the scanning shell 21 will not be affected.

[0083] Exemplarily, the width b2 of the scanning housing 21 can be set to 19mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm, 42mm, 45mm, 50mm, 52mm, 55mm, 60mm, 70mm or more. However, it should be noted that when the width b2 of the scanning housing 21 is selected, the ratio of the width b2 of the scanning housing 21 to the width b1 of the host 10 should be considered at the same time. For example, when the width b1 of the host 10 is 55mm, the width b2 of the scanning housing 21 should satisfy the above ratio relationship and be smaller than the width b1 of the host 10.

[0084] Furthermore, the width b2 of the scanning housing further satisfies: 25mm≤b2≤35mm. Combined with the above, the width b1 of the host satisfies: 50mm<b1≤70mm. It can be seen that the width of the scanning housing is approximately half of the width of the host. In this way, the width difference between the scanning housing and the host can be further increased, and the width b2 of the scanning housing is roughly adapted to the width of the pen body of a conventional scanning pen on the market, so that it can be adapted to be held by users with small hands. In other words, the present application adopts the method of increasing the width b1 of the host, which is far greater than the pen body width of the scanning pen on the market. At the same time, combined with the width of the scanning housing roughly maintaining the width of the pen body of the scanning pen on the market, and the scanning housing has a certain length for holding, to achieve a method in which users with small hands can hold the scanning housing, while users with large hands can choose to hold the host or the scanning housing, thereby solving the problem of reduced user adaptability of holding the device with one hand due to the increase in the width of the host 10 and the display screen 30 (for example, children cannot hold it or cannot hold it for a long time).

[0085] In some embodiments, the width b2 of the scanning housing 21 gradually decreases in the direction away from the host 10, and a connection transition surface (not shown) can be formed between the side surface of the scanning housing 21 along the width direction Y of the host 10 and one end surface of the host 10. The connection transition surface can be an inclined surface or an arc surface. In this way, the width transition between the scanning housing 21 and the host 10 is more natural, and it is not only more convenient for users to hold, but also can meet the scanning focus problem of the end of the scanning housing 21 away from the host 10. In addition, the design of the connection transition surface can also limit the user's grip on the scanning housing 21. For example, when holding, the user can place the part of the thumb or index finger near the base of the thumb against the connection transition surface, so that the connection transition surface can be used to limit the position of the user's thumb or index finger near the base of the thumb, so that the user can hold with less effort.

[0086] It should be noted that if the width b2 of the scanning housing 21 gradually decreases along the direction of the host 10 , the ratio of the width b2 of the scanning housing 21 to the width b1 of the host 10 refers to: the ratio of the maximum value of the width b2 of the scanning housing 21 to the width b1 of the host 10 .

[0087] In addition, the scanning housing 21 gradually decreases along the width b2 in the direction away from the host 10, so that the side of the scanning housing 21 along the length direction of the host 10 can gradually shrink from the end close to the host 10 to the end away from the host 10 to form a convergence curved surface 20a. That is to say, in the Y direction, both sides of the scanning housing 21 can have convergence curved surfaces 20a, and the user can hold it on the convergence curved surface 20a. When the scanning pen 01 is unfolded, the convergence curved surface 20a can converge in the direction away from the host 10. In other words, the width of the scanning component 20 can gradually decrease in the direction away from the host 10 to facilitate the user's holding, and also make the width transition of the scanning housing 21 more natural.

[0088] In some other embodiments, the width b2 of the scanning housing 21 is roughly uniformly set in the length direction X of the host 10, that is, the width of the end of the scanning housing 21 connected to the host 10 is roughly equal to the width of the end of the scanning housing 21 away from the host 10. In this way, the overall width of the scanning housing 21 is uniform, and the user can hold the scanning housing 21 at any position, and the grip adaptability is good. It can be understood that the width b2 of the scanning housing 21 is roughly uniform, which means that its width is roughly equal, but the scanning housing 21 is allowed to have some changes. For example, there may be a few concave-convex structures in the scanning housing 21, and the concave-convex structure has little effect on the overall width of the scanning housing 21. For example, if it is a protruding design, the protruding position is approximately protruding within 0-5mm compared to other positions of the scanning housing 21. At this time, it can be considered that the width of the scanning housing 21 is roughly uniform.

[0089] As can be seen from the above, the scanning housing 21 has a certain length in the length direction X of the host 10, and the certain length meets the requirement that the scanning housing 21 can be held. That is, when the scanning housing 21 has a certain length, as long as it can accommodate the thumb and index finger of the human body, in this case, it can be considered that the scanning housing 21 has the holding condition, and the user can hold the scanning housing 21 according to the selection. In some embodiments, the length L0 of the scanning housing 21 in the length direction X of the host 10 can be greater than or equal to 15mm, so that the scanning housing 21 can be held. The inventor found through research that when the length L0 of the scanning housing 21 is 15mm, the length just matches the length of the thumb and index finger of most users, that is, as long as the length of the scanning housing 21 is greater than or equal to 15mm, the scanning housing 21 can be held.

[0090] The length L0 of the scanning housing 21 may further satisfy: 15mm≤L0≤100mm, for example, 15mm, 19mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. This is because, according to research, when the length L0 of the scanning housing 21 is 100mm, it is just enough for most users to hold the scanning housing 21, and the scanning housing 21 still has enough length space to rest on the user's thumb. In other words, this length is a length that is convenient for the thumb to hold and rest. It can be seen that the scanning housing 21 of the present application adopts the above-mentioned length range, not only simply considering its gripping ability, but also further considering the different gripping methods adapted to different users, that is, it not only considers the gripping method that the user can only hold the scanning housing 21 with the thumb and index finger, and the host 10 is against the base of the thumb, but also considers the gripping method that the user holds the scanning housing 21 with the thumb and index finger, and the scanning housing 21 has enough length margin to be against the base of the thumb, which effectively adapts to the different gripping methods of different users and has better adaptability. For example, an adult user has a larger base of the thumb, and at this time, only the scanning housing 21 can be held, but the host 10 is against the base of the thumb; while the base of a child user is smaller, so the scanning housing 21 with a smaller width is against the base of the thumb, which is more comfortable to hold and is conducive to long-term gripping and use by the child user.

[0091] On the basis of the above-mentioned length range of the scanning housing 21, the width range of the scanning housing and the width range of the host, the present application further considers the length L of the host 10 in order to take into account the problem that the overall length of the scanning pen 01 cannot be too long, because it is inconvenient for children to carry and use it. Specifically, the length L of the host 10 can roughly meet the following conditions: 40mm≤L≤150mm. Exemplarily, it can be 40mm, 45mm, 50mm, 55mm, 60mm, 70mm, 70mm, 80mm, 90mm, 100mm, 110mm, 115mm, 120mm, 130mm, 140mm, 150mm, etc., that is, the length of the host 10 can be further limited to 70mm-120mm. As can be seen from the above, the width b1 of the host 10 also satisfies 50mm≤b1≤70mm, that is, on the basis of widening the width of the host 10, so that the host 10 has a sufficient display area and the scanning housing 21 also has a certain length and width, the length of the host 10 can be appropriately made smaller, so that the length-to-width ratio of the host 10 can be roughly within the range of 1.5:1-3:1, so that the length-to-width ratio of the host 10 is appropriate, so that the appearance of the host 10 is roughly similar to the appearance of a small mobile phone on the market, which is different from the slender scanning pen design. With such a design, on the basis of widening the host 10, the length of the entire scanning pen can be taken into account not being too long, so as to prevent the situation where the scanning pen is too long and inconvenient for users to carry.

[0092] In addition, based on the above considerations of the width and length of the host 10 and the width and length of the scanning housing 21, the present application further considers the length ratio of the scanning housing 21 to the length of the host 10. Specifically, if the length of the scanning housing 21 is L0 and the length of the host 10 is L, then 0.5L≤L0≤L. This is equivalent to the length of the scanning housing 21 being greater than or equal to more than half of the length of the host 10. In this way, the overall length of the scanning housing 21 can be controlled within a reasonable range while taking into account the realization of gripping, so as to avoid the situation where the scanning pen 01 is too long and inconvenient to carry and use.

[0093] Furthermore, the length L0 of the scanning housing 21 can be, for example, 0.5L, 0.6L, 0.7L, 0.8L, 0.9L or L, etc., and the final length L0 of the scanning housing 21 needs to be determined according to the width of the scanning housing 21, the width of the host 10 and the overall length of the scanning pen 01. It can be seen that when determining the length L0 of the scanning housing 21, it is not only necessary to consider whether it can be held, but also the overall length of the scanning pen 01, the ratio of the width of the scanning housing 21 to the width of the host 10 and the accommodation space of the scanning housing 21 itself.

[0094] Considering that the purpose of increasing the width of the host 10 is to provide a display screen 30 with a larger display area, based on this, in this application, corresponding considerations are also made for the size of the display screen 30, which will be explained separately below.

[0095] First, based on the width of the above-mentioned host 10 and the width of the scanning shell 21, the present application also considers the width of the display screen 30. Specifically, the width b3 of the display screen 30 may be greater than the width of the scanning shell 21, and the width b3 of the display screen satisfies: b1-10≤b3≤b1-1, in mm. In other words, the width of the display screen 30 is slightly smaller than the width of the host. For example, when the width of the host is 20mm-100mm, the width b3 of the display screen 30 may satisfy, for example: 10mm≤b3≤99mm. And when the width of the host is 30mm-80mm, the width of the display screen 30 may satisfy: 20mm≤b3≤79mm. In short, the width of the display screen of the present application is slightly smaller than the width of the host, which is equivalent to that when the display screen is set on the host, the display screen can be roughly a full screen, so that the display area is larger.

[0096] Exemplarily, the width of the display screen may be, for example, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 95 mm, etc.

[0097] Secondly, based on the width of the host 10, the width of the scanning shell 21, and the length of the host 10, the present application also considers the length of the display screen 30. Specifically, the length of the display screen 30 can also be roughly adapted to the length of the host 10, so that the display screen can be roughly a full screen, that is, the length of the display screen 30 can be slightly smaller than the length of the host 10, for example, the length L1 of the display screen satisfies: L-10≤L1≤L-1, in mm. For example, when the length of the host is 40mm-150mm, the length of the display screen can satisfy 30mm≤L1≤149mm, or, when the length of the host satisfies 50mm-120mm, the length of the display screen can satisfy 40mm≤L1≤119mm. In this way, the display screen 30 roughly covers the surface of the host 10, so that a display effect close to a full screen can be achieved.

[0098] Again, based on the width of the host 10, the width of the scanning shell 21, and the length of the host 10, the present application further considers the size of the display screen 30, for example, the size S of the display screen 30 satisfies: 3 inches ≤ S ≤ 7 inches. In other words, the display screen 30 of the present application has a display size of approximately 3 inches, 4 inches, 5 inches, 6 inches, 7 inches, or other larger screen or large screen display sizes, so that the scanning pen 01 has a larger display area, and thus the scanning pen can realize multi-line display or can display larger fonts on a page, and can even use a larger screen video display effect, and the user's reading experience and operation experience are better.

[0099] Considering that the host 10 has a relatively large width, while the width of the scanning housing 21 is smaller than that of the host 10, and at the same time, the scanning housing 21 has a certain length, in this way, users with small hands can choose to hold the scanning housing 21. Since the scanning housing 21 is at one end of the length direction X of the host 10, because the overall size of the host 10 is relatively large, and the host 10 carries devices such as the display screen 30, the host 10 is relatively heavy, and the center of gravity of the scanning pen 01 may be offset to the end of the host 10 away from the scanning component 20. This results in a greater torque in the direction of the center of gravity of the scanning pen when the user holds the scanning housing 21, especially when a child user holds it, the hand needs to apply a greater force to clamp the scanning pen, otherwise the top may be heavy, that is, the host 10 may overturn. Based on this, the present application also considers the distribution of the center of gravity of the scanning pen 01. Specifically, the present application limits the overall weight of the scanning component 20 to be less than or equal to the overall weight of the host, so that the center of gravity of the scanning pen 01 can be adjusted toward one end of the host 10 close to the scanning component 20, thereby alleviating the problem that when the user holds the scanning shell 21, the overall weight of the scanning shell 21 is too light, while the overall weight of the host 10 is too heavy, resulting in top-heavy condition, that is, alleviating the possibility that the host 10 may overturn when held.

[0100] In some embodiments, the present embodiment also considers that the ratio of the overall weight of the scanning component 20 to the overall weight of the host 10 is greater than or equal to a preset threshold. Specifically, the preset threshold may be M, and M satisfies: 0.1≤M≤1. Exemplarily, M may be 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.8 and 0.9, etc. Thus, the overall weight of the scanning component 20 can be slightly closer to the overall weight of the host 10, so as to avoid the problem that the scanning pen 01 is tilted toward the end of the host 10 away from the scanning component 20 when the scanning pen 01 is held on the scanning housing 21 due to the large weight difference between the two, thereby requiring the user to exert greater force to hold the scanning housing 21 tightly, affecting the user's holding experience.

[0101] Furthermore, the preset threshold value M may further satisfy: 0.25≤M≤1. That is to say, the overall weight of the scanning component 20 is closer to the overall weight of the host 10, so that the center of gravity of the scanning pen 01 can be more offset toward the end of the host 10 close to the scanning component 20, and even the center of gravity of the scanning pen 01 may fall on the scanning component 20. In this way, when the user holds the scanning housing 21, the gravity of the host 10 has a reduced effect on the center of gravity of the scanning pen 01. When the user holds the scanning pen 01, the center of gravity will be offset toward the scanning component 20 due to the gravity of the scanning component 20. When the user holds the scanning housing 21, the scanning pen 01 will actively lean forward toward the end of the scanning housing 21 away from the host 10 due to the gravity, so that the user does not need to use too much force to clamp the scanning pen 01, and the scanning pen 01 will not fall toward the host 10, thereby reducing the clamping force applied by the user when holding the scanning pen 01 and improving the user's holding experience.

[0102] In other embodiments, considering the overturning problem when holding the scanning housing 21, the scanning housing 21 can be counterbalanced based on the position of the center of gravity. Specifically, in the length direction X of the host 10, the distance L2 from the center of gravity O of the scanning pen 01 to the end face of the host 10 connected to the scanning housing 21 is less than or equal to 2 / 3 of the length L of the host 10. For example, the distance L2 from the center of gravity O of the scanning pen 01 to the end face of the host 10 connected to the scanning housing 21 can be 1 / 3L, 1 / 2L or 2 / 3L, etc. In other words, the center of gravity O of the scanning pen 01 is close to the end of the host 10 connected to the scanning housing 21. In this way, when counterbalance is performed on the scanning housing 21, as long as the center of gravity O of the scanning pen 01 can be in the above position, the overturning problem when holding the scanning housing 21 can be alleviated.

[0103] It is understandable that the above Figure 2 In the figure, the center of gravity of the scanning pen 01 is simply shown for the sake of convenience, and the center of gravity is not limited to Figure 2 In addition, the position of the center of gravity of the scanning pen 01 can be determined according to the suspension method or support method in the relevant technology, which will not be described in detail in this embodiment.

[0104] It is understandable that there are different ways to make the center of gravity of the scanning pen shift as far as possible to the end of the host closer to the scanning component, which will be explained in detail below.

[0105] In some embodiments, the position of the internal components in the host 10 and / or the scanning component 20 can be adjusted by arranging the internal components. For example, a battery with a certain weight can be arranged in the scanning component 20, or the battery can be arranged at one end of the host 10 close to the scanning component 20. Alternatively, a part of the battery can be arranged in the scanning component 20, and another part of the battery can be arranged in one end of the host 10 close to the scanning component. Alternatively, the battery can be arranged in the scanning component 20, and other internal components, such as a microphone, a circuit board, etc., can be arranged at one end of the host 10 close to the scanning component 20.

[0106] The above method can optimize the arrangement design of internal components in the host 10 and the scanning component 20 through the arrangement of internal components. On the other hand, the internal components can also be used to concentrate the weight on one end of the host 10 close to the scanning component 20 or the scanning component 20, so that the center of gravity of the scanning pen 01 can be shifted to the end of the host 10 close to the scanning component 20.

[0107] In some other embodiments, a counterweight can also be used. Specifically, in one example, the scanning housing 21 can be provided with a counterweight (not shown). By using the counterweight, the overall weight of the scanning assembly 20 can be increased, so that the center of gravity of the scanning pen 01 can be adjusted toward the host 10 toward the scanning housing 21, thereby alleviating the situation where the user may be top-heavy when holding the scanning housing 21, that is, alleviating the situation where the host 10 may tip over when holding it.

[0108] Optionally, the counterweight may include at least one of a battery and a counterweight. For example, the counterweight may be an additional counterweight (such as a magnet, a metal block, etc.), or the counterweight may be a battery provided by the scanning pen 01, that is, the battery of the scanning pen 01 is installed in the scanning housing 21. This method can utilize the certain length space of the scanning housing 21 to make the spatial layout of the host 10 more flexible, and can also utilize the weight of the battery itself to counterweight the scanning housing 21. Of course, it is also possible to add a battery and a counterweight as a counterweight in the scanning housing 21 at the same time. In other optional methods, the scanning pen 01 may also include dual batteries. For example, a first battery may be provided in the scanning housing 21, and a second battery may be provided in the host 10. The first battery may counterweight the scanning housing 21, and the first battery may also power the scanning module 23 provided with the scanning housing 21. The second battery in the host 10 can power other devices in the host 10, such as the display screen 30, so that different devices are powered by different batteries, and the power connection method is simpler. In addition, the dual-battery design can also improve the battery life of the scanning pen 01.

[0109] Of course, in other embodiments, the structure of the scanning component 20 itself can also be counterweighted. For example, the scanning housing 21 is usually made of plastic. If counterweight is desired, the scanning housing 21 can be made of, for example, a beer-in-place process, and a metal part can be embedded inside the scanning housing 21. The embedded metal part can, on the one hand, be used as a counterweight to counterweight the scanning component 20; on the other hand, the metal part can also enhance the structural strength of the scanning housing 21. In this case, even if the scanning housing 21 is made of plastic, a plastic part with lower structural strength, such as soft rubber, can be selected according to demand, so that when the user holds the scanning housing 21, the gripping feel is better.

[0110] Alternatively, in other embodiments, the scanning shell itself can be used as a counterweight. Specifically, the scanning shell 21 can be made of, for example, metal, and the host shell can be made of, for example, plastic. In this way, the scanning shell 21 itself can be used as a counterweight, that is, the scanning shell 21 can play a counterweight role for the scanning component 20 due to its own weight of the metal material. At the same time, the scanning shell 21 made of metal can have good structural strength, so that the scanning shell 21 is less likely to be damaged when it falls or hits.

[0111] In another example, a counterweight can also be provided at one end of the host 10 close to the scanning component 20. In this way, the center of gravity of the scanning pen 01 can be shifted as much as possible to the end of the host 10 close to the scanning component 20. Generally speaking, even if the user holds the host 10, he will hold it at a relatively forward position of the host 10, that is, the host 10 is closer to the scanning housing 21. Therefore, a counterweight is provided at one end of the host 10 close to the scanning component 20, and the center of gravity is closer to the holding part. When the user holds the scanning pen 01, it is easier to press the scanning pen 01 down to abut against the scanned object, making it easier for the user to hold.

[0112] In this embodiment, the counterweight may also include at least one of a battery and a counterweight block. For example, the counterweight may be an additional counterweight block (such as a magnet block, a metal block, etc.), or the counterweight may be a battery provided by the scanning pen 01, that is, the battery of the scanning pen 01 is installed at the end of the host 10 close to the scanning component 20, so that the weight of the battery itself can be used to counterweight the end of the host 10 close to the scanning component 20. Of course, a battery and a counterweight block may also be added to the scanning housing 21 as counterweights at the same time.

[0113] In other ways, the structure of the host 10 itself can also be counterweighted. For example, the host shell is usually made of plastic parts. The host shell can adopt the beer-jacketing process, and a metal part is embedded at the end of the host shell close to the scanning component 20. The metal part is used as a counterweight. At the same time, the metal part can also be used to strengthen the structural strength of the host shell. In this way, when grooves or holes are opened on the host shell for connection or other structural parts are set, the host shell can also have sufficient structural strength. Alternatively, the host shell can be split in the length direction. For example, the shell part at the end connected to the scanning component 20 can be made of metal, and the shell part at the end away from the scanning component 20 can be made of, for example, plastic material. In this way, the end of the host 10 close to the scanning component 20 can also be counterweighted.

[0114] In some other embodiments, a counterweight may be provided at the scanning housing 21 and at the end of the host 10 close to the scanning housing 21. For example, a counterweight may be provided in the scanning housing 21, and at the end of the host 10 close to the scanning housing 21, or a counterweight may be provided in the scanning housing 21, and at the same time, the counterweight may extend to the end of the host 10 close to the scanning housing 21, so that the same counterweight is provided in the scanning housing 21 and the host 10. In this embodiment, the specific structure and counterweight method of the counterweight may refer to the above description, and will not be repeated here.

[0115] Please also read Figures 4 to 6 ,in, Figure 4 is a schematic diagram showing the scanning component 20 of the present application in a storage state relative to the host 10. Figure 5 The scanning assembly 20 is also in the storage state, but the user can face the schematic diagram of the display screen. Figure 6 1 is a schematic diagram of the scanning component 20 of the present application unfolded relative to the host 10. Considering that the host 10 is relatively wide, when the scanning component 20 is not needed to perform the scanning function, the display screen 30 on the host 10 can be used for other functions, such as video viewing, page reading, etc. At this time, it can be considered to fold the scanning component 20 relative to the host 10, which is convenient for operating the display screen 30 on the host 10 and can also protect the scanning component 20. Based on this, in some embodiments, the scanning component 20 can be rotatably connected to one end of the host 10 through the shaft component 100, so that it can be folded or unfolded relative to the host 10.

[0116] Specifically, the host 10 may include a first surface 10a and a second surface 10b facing each other. The first surface 10a may be provided with the display screen 30. The display screen 30 may cover the entire first surface 10a of the host 10, that is, in the XY plane, the area of ​​the display screen 30 may be roughly the same as the area of ​​the host 10, thereby increasing the display area.

[0117] When the scanning housing 21 is rotatably connected to one end of the host 10 through the rotating shaft assembly 100, it can be rotated relative to one end of the host 10 to be folded on the second surface 10b of the host 10, or it can be rotated relative to one end of the host 10 to be away from the second surface 10b of the host 10 and unfolded relative to the second surface 10b of the host 10. In other words, the scanning housing 21 has at least a storage state relative to the host 10 (i.e., folded relative to the host 10), or it can have an unfolded state (i.e., unfolded relative to the host 10). In the storage state, the scanning assembly 20 is folded relative to the host 10 as a whole. At this time, the scanning assembly 20 cannot realize the scanning function, and the user can use the display screen 30 with a larger display area on the host 10 to realize video watching, web page reading, etc. In the unfolded state, the scanning assembly 20 is unfolded relative to the host 10 as a whole. At this time, the scanning module 23 can realize scanning normally, so that the display screen 30 can display the content scanned by the scanning module 23.

[0118] It can be seen that the scanning pen 01 of the embodiment of the present application can have a scanning mode of the scanning component 20 to meet the needs of users when scanning and learning. It can also have a video display mode of the display screen 30 to meet the user's use needs for large-screen display in learning scenarios, so that the user can switch different scenarios of the scanning pen 01 according to their own needs.

[0119] In addition, the scanning pen of the present application increases the display area of ​​the display screen 30 by widening the host 10. In this case, if the conventional design is used, the length of the host 10 needs to be lengthened at the same time as the host 10 is widened. However, the present application does not deal with this. The present application adopts the method of widening the host 10 while further considering that the scanning housing 21 has a certain length for holding. In this case, in order to take into account the overall length of the scanning pen 01 itself and make it not too long (the overall length of the scanning pen on the market is generally between 140mm-180mm), based on this, the present application makes the scanning component 20 where the scanning housing 21 is located rotatable and foldable relative to the host 10, so that the length of the folded scanning pen 01 is actually roughly the length of the host 10 (the above-mentioned 40mm-150mm), that is, the overall length of the folded scanning pen of the present application is shorter than the overall length of the conventional scanning pen on the market. When the scanning function is not needed, the width and length of the host 10 can be adapted to the user's usage habits (especially the use of users with small hands), and it is also convenient for users to carry because of the shorter length, for example, it can be convenient for users to put it in their pockets. When the scanning function is needed, the scanning component 20 is unfolded relative to the host 10. The overall length of the unfolded scanning pen 01 is roughly compatible with the length of scanning pens on the market, which is in line with the user's usage habits.

[0120] In addition, since the scanning component of the present application is foldable relative to the host 10, that is, the present application makes the scanning component 20 and the host 10 into two modules, and the two modules are connected to each other through the shaft component 100. In this way, when the scanning component 20 is folded relative to the host 10, the host 10 is still a complete module, which can realize functions such as page display and video playback. When the scanning component 20 is unfolded relative to the host 10, the scanning component 20 and the host 10 form a complete scanning pen 01, thereby realizing the scanning function.

[0121] As can be seen from the above, the center of gravity O of the scanning pen 01 (see above Figure 2 ) is close to the end where the host 10 is connected to the scanning housing 21. Based on this, when the scanning housing 21 is rotatably connected to the host 10 through the rotating shaft assembly 100, in the length direction X of the host 10, the distance from the center of gravity of the scanning pen 01 to the rotation axis of the rotating shaft assembly 100 is less than or equal to 2 / 3 of the length of the host 10, that is, in the length direction X of the host 10, the center of gravity of the scanning pen is located within 2 / 3 of the rotation axis of the host 10 close to the rotating shaft assembly 100. In this way, the center of gravity of the scanning pen 01 can be shifted toward the direction where the host 10 is close to the scanning assembly 20, thereby avoiding the problem of top-heavy when the user holds it. On this basis, when balancing the weight of the scanning housing 21, the weight can be roughly balanced with reference to the above-mentioned center of gravity position.

[0122] In this case, when the scanning component 20 is rotatable relative to the host 10, so that the scanning component 20 and the host 10 actually form two modules, in the above-mentioned counterweight method adopted in the scanning component 20, if the scanning shell 21 of the scanning component 20 is counterweighted by using the lamination process and embedding metal parts in the scanning shell 21, then the embedding position of the metal parts can at least cover the connection between the scanning shell 21 and the shaft assembly 100. In this way, the metal parts can be used to strengthen the structural strength of the connection between the scanning shell 21 and the shaft assembly 100, thereby preventing the stress concentration at the connection with the shaft assembly 100, which may cause breakage or breakage after multiple rotations.

[0123] Similarly, if the host shell is subjected to the beer-jacketing process and the counterweight is achieved by embedding metal parts in the host shell, then, accordingly, the embedding position of the metal parts can also at least cover the connection between the host shell and the shaft assembly 100. In this way, the structural strength of the host shell at the rotating connection can be strengthened to avoid the situation where the stress concentration during rotation may cause breakage or breakage after multiple rotations.

[0124] Considering that the scanning housing 21 can be rotated relative to the host 10 to be folded on the second surface 10b of the host 10, in this case, the overall thickness of the scanning pen 01 increases in the thickness direction of the host 10. At this time, the overall thickness of the scanning pen 01 is the thickness of the host 10 plus the thickness of the scanning housing 21, so that it is inconvenient for users, especially users with small hands, to hold the scanning pen in the video display mode. Therefore, in some embodiments, a storage groove 11c may be provided on the second surface 10b, and the scanning component 20 may be rotated to be stored in the storage groove 11c to be folded on the host 10, or may be rotated to be separated from the storage groove 11c to be unfolded relative to the host 10. In other words, in the storage state, the scanning component 20 may be stored in the storage groove 11c. On the one hand, the setting of the storage groove 11c can reduce the impact on the overall thickness of the scanning pen 01, and on the other hand, the storage groove 11c can also be used to protect the scanning component 20.

[0125] Optionally, along the length direction X of the main machine 10, the storage groove 11c passes through one end of the main machine 10 connected to the scanning housing 21, so that the shaft assembly 100 connecting the main machine 10 and the scanning housing 21 can be roughly located at the penetration of the storage groove 11c, so that the scanning assembly 20 can be rotated and folded into the storage groove 11c or rotated out of the storage groove 11c. That is, the storage groove 11c has a groove bottom surface 11a and two groove side walls 11b along the width direction, and a groove top wall 11d along the length direction of the main machine 10.

[0126] Optionally, considering that the scanning component 20 is stored in the storage slot 11c, based on this, in order to provide a buffer when the scanning component 20 is rotated and stored in the storage slot 11c, to prevent the scanning component 20 from rotating too much or being directly impacted on the bottom surface 11a of the storage slot 11c, thereby causing damage to the scanning housing 21 of the scanning component 20 or impacting other structures inside the scanning housing 21, a buffer pad 11e can be provided on the bottom surface 11a of the storage slot 11c, and the buffer pad is arranged close to the top wall 11d of the slot, and the buffer pad 11e can be provided on the bottom surface 11a of the storage slot 11c. There can be two pads 11e, which are arranged near the two groove side walls 11b along the width direction Y. Therefore, when the scanning component 20 is stored in the storage groove 11c, the buffer pad 11e can play a certain buffering role on the scanning component 20. At the same time, because the buffer pad 11e is in the shape of a long strip, the contact area between the buffer pad 11e and the scanning component 20 is much smaller than the contact area between the scanning component 20 and the groove bottom surface 11a, thereby avoiding direct contact between the scanning component 20 and the groove bottom surface 11a of the storage groove 11c, thereby avoiding scratches on the surface of the scanning shell 21.

[0127] In order to better demonstrate the contents of the embodiments of the present application, the following embodiments will provide a detailed introduction to the specific application scenarios of the scanning pen 01 in combination with the design of the storage slot 11 c.

[0128] Please also read Figure 7 and Figure 8 , Figure 7 1 is a schematic diagram of the structure of the host housing 11 of the present application (the scanning component 20 is omitted in the figure). The host 10 may include a host housing 11, the host housing 11 and the scanning housing 21 are connected, the host housing 11 may include a first housing 101 and a second housing 102 connected to each other, the first housing 101 may have the above-mentioned first surface 10a, and the second housing 102 may have the above-mentioned second surface 10b.

[0129] Furthermore, considering that the second surface 10b has the above-mentioned storage groove 11c, the scanning component 20 can be stored in the storage groove 11c. Based on this, the first housing 101 can also include a third surface 10d facing the same direction as the second surface 10b, and the second surface 10b is protruded relative to the third surface 10d in the direction from the first surface 10a to the second surface 10b. In this way, when the second surface 10b has the storage groove 11c, the storage groove 11c can be recessed more space from the direction from the second surface 10b to the first surface 10a, so that when the scanning component 20 is stored in the storage groove 11c, it can be stored in the storage groove 11c as much as possible, so that the storage scanning pen 01 is more compact and has a flatter appearance. Of course, in other embodiments, the second surface 10b can also be roughly flush with the third surface 10d or slightly lower than the third surface 10d.

[0130] Optionally, a through slot penetrating to the first surface 10a may be provided on the third surface 10d of the first shell 101, so that the display screen 30 is arranged on the first surface 10a to cover the opening of the through slot on the first surface 10a, and the second shell 102 is arranged on the third surface 10d to cover the opening of the through slot on the third surface 10d. That is to say, along the width direction Y of the host 10, the width of the second shell 102 is smaller than or slightly smaller than the width of the first shell 101, so that when the second surface 10b protrudes relative to the third surface 10d, when viewed from the second surface 10b to the first surface 10a, the third surface 10d is surrounded by the periphery of the second surface 10b, that is, the second surface 10b protrudes relative to the part of the third surface 10d, and the overall appearance of the scanning pen 01 is more three-dimensional.

[0131] In some embodiments, the outer periphery (e.g., corners) of the first housing 101 may be provided with an anti-collision portion 101a, and the anti-collision portion 101a may be provided protruding from the first housing 101. As can be seen from the foregoing, the host 10 is roughly rectangular, so the first housing 101 may have four corners, and the anti-collision portion 101a may be provided at the four corners of the first housing 101. Thus, by using the anti-collision portion 101a, when the host 10 falls or is hit, the anti-collision portion 101a can protect the first housing 101 and the devices provided on the first housing 101, such as the display screen 30, the speaker, etc., to prevent these devices from being hit or falling and causing damage or failure. Of course, in other embodiments, the above-mentioned anti-collision portion 101a may be provided not only at the corners of the first housing 101, but also at the approximately middle position of the first housing 101 along the length direction, so that the protection of the first housing 101 can be further increased.

[0132] It is understandable that, since the anti-collision portion 101 a is disposed on the periphery of the host housing 11 , the width b1 of the host 10 can be the distance between the two anti-collision portions 101 a on both sides along the width direction Y of the host 10 .

[0133] Furthermore, a transition surface 1011 is formed between the outer surface of the anti-collision portion 101a and the outer surface of the first shell 101. The transition surface 1011 may include a slope and / or a curved surface. In this way, no sharp angle is formed between the outer surface of the anti-collision portion 101a and the outer surface of the first shell 101, thereby avoiding discomfort to the user's hands when taking the host 10.

[0134] Optionally, the transition surface 1011 of the anti-collision part 101a located at one end where the first shell 101 is connected to the scanning assembly 20 forms a gripping position for holding. Specifically, along the length direction X of the first shell 101, at least the transition surfaces 1011 of the two anti-collision parts 101a located at one end where the first shell 101 is connected to the scanning shell 21 can form a gripping position for the user to hold, so that when the user holds the host 10, the transition surface 1011 can be used as a gripping position, that is, the user can place the thumb and index finger against the two transition surfaces 1011 in the width direction Y of the first shell 101, respectively, so that on the one hand, it can play a role in positioning and limiting the user's holding of the host 10, and on the other hand, the design of the transition surface 1011 can also be more adapted to the surface of the user's thumb and index finger, so as to provide a better gripping experience. Of course, it is understandable that not only the transition surface 1011 of the anti-collision part 101a located at one end where the first shell 101 is connected to the scanning component 20 forms the above-mentioned holding position, but the transition surfaces 1011 of the anti-collision part 101a at other positions of the first shell 101 can also form the above-mentioned holding position, so that the anti-collision part 101a can be formed all at once when it is formed, without the need for a separate design, and the process is simpler. In addition, the overall appearance of the main unit 10 is consistent, and the appearance decorative effect is better.

[0135] Furthermore, the transition surface 1011 may be an inclined surface, which extends from the anti-collision portion 101a to the side surface of the first shell 101 in the width direction Y, so that an angle β greater than or equal to 90° and less than or equal to 180° may be formed between the inclined surface and the side surface of the first shell 101. In this way, when the user holds it, it can better adapt to the abutment of the user's thumb and index finger, and the gripping and positioning effect is better.

[0136] Furthermore, the angle β can also be exemplarily 105°-175°, such as 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 170° or 175°, etc. If the angle is an obtuse angle, the side inclined toward the first shell 101 is smoother, thereby forming a larger inclined surface area, which is more conducive to user holding.

[0137] Please continue reading Figure 7 and Figure 8 , Figure 8The structure of the protective shell of the present application is shown. In some embodiments, the host shell 11 also includes a protective shell 10e, which is coated on the outer periphery of the first shell 101, and the protective shell 10e is integrally arranged with the first shell 101, and the two are inseparable. Specifically, considering that the host 10 is a long strip-shaped host 10, the protective shell 10e is a long strip-shaped shell, and the protective shell 10e is provided with the above-mentioned anti-collision part 101a at the four corners corresponding to the first shell 101. The anti-collision part 101a protrudes from the surface of the protective shell 10e, so that when the host 10 falls or is hit, the anti-collision part 101a can protect the first shell 101 and the devices provided on the first shell 101, such as the display screen 30, the speaker, etc., to prevent these devices from being damaged or failing due to impact or falling. Of course, it is understandable that in other embodiments, the protective shell 10e can also be connected to the first shell 101 in a detachable manner. For example, the protective shell 10e can be sleeved on the outer periphery of the first shell 101, so that the protective shell 10e can be replaced according to user selection.

[0138] Exemplarily, the protective shell 10e can be made of the same or different material as the first shell 101. For example, when the first shell 101 is made of hard plastic, the protective shell 10e can be made of hard plastic or soft rubber, preferably soft rubber, so that when the user holds the host 10, the grip is better, and the soft rubber has better elasticity and better anti-collision and anti-fall performance. The anti-collision portion 101a can be a protruding anti-collision block or anti-collision strip, and its material can be selected from silicone or rubber with a certain elasticity, which can be selected according to actual conditions, and this embodiment does not specifically limit this.

[0139] Please combine the above Figure 7 , read together Fig. 9 and Fig.10 , Fig. 9 is a schematic diagram of the internal structure of the host housing 11 of the present application, Fig.101 is a partial structural exploded diagram of the host housing 11 of the present application. In some embodiments, a host cavity 12 may be formed in the host 10, and the host cavity 12 may be formed by connecting the first housing 101 and the second housing 102. When a receiving groove 11c is formed on the second surface 10b, the receiving groove 11c may be recessed from the second surface 10b in a direction relative to the first surface 10a, and a protrusion 1012 may be formed in the host cavity 12, so that the host cavity 12 is divided into a first cavity 120a and a second cavity 121a, and the first cavity 120a may be arranged corresponding to the protrusion 1012. In other words, the second shell 102 has a protruding portion 1012 corresponding to the storage groove 11c on the side facing away from the second surface 10b. The protruding portion 1012 can, on the one hand, block the connection between the storage groove 11c and the inside of the main cavity 12, and on the other hand, can strengthen the structural strength of the second shell 102 at the storage groove 11c, thereby preventing the second shell 102 from being easily deformed at the storage groove 11c.

[0140] Further, the host cavity 12 is divided into a first cavity 120a and a second cavity 121a by using the protrusion 1012. The first cavity 120a is arranged corresponding to the storage groove 11c. Then, in the thickness direction of the host 10, the depth of the first cavity 120a is less than the depth of the second cavity 121a. Based on this, the arrangement of the components in the host 10 can be designed according to the different depths of the first cavity 120a and the second cavity 121a. For example, the circuit board (not shown) and the speaker (not shown) in the host 10 can be arranged in the first cavity 120a and / or the second cavity 121a. In one example, the circuit board and the speaker can be arranged in the first cavity 120a, and the second cavity 121a can be arranged with other components, such as batteries. In another example, the circuit board and the speaker can be arranged in the second cavity 121a. In this case, the first cavity 120a can be arranged with components or not. Since the depth of the second cavity 121a is greater than that of the first cavity 120a, the circuit board and the speaker are arranged in the second cavity 121a, and the space of the second cavity 121a can be reasonably utilized. At the same time, no device is arranged in the first cavity 120a, so that the scanning pen 01 can be made thinner at the first cavity 120a, that is, the storage groove 11c can be made deeper, which is more conducive to the overall storage of the scanning component 20. In another example, one of the circuit board and the speaker can be arranged in the first cavity 120a, and the other of the circuit board and the speaker can be arranged in the second cavity 121a. For example, since there are many circuits and components on the circuit board, it can be arranged in the second cavity 121a, and the speaker can be arranged in the first cavity 120a. Alternatively, the circuit board can be arranged in the first cavity 120a, and then the speaker can be arranged in the second cavity 121a. In this way, according to the volume of different devices, the space of the first cavity 120a and the second cavity 121a can be reasonably utilized to achieve a reasonable arrangement.

[0141] Of course, as another example, a portion of the circuit board may be disposed in the first cavity 120a, and another portion of the circuit board may extend into the second cavity 121a, and the speaker may be disposed in the second cavity 121a. Alternatively, the circuit board may be divided into a plurality of boards, one of which is disposed in the first cavity 120a, and the other boards are disposed in the second cavity 121a.

[0142] Considering that the first cavity 120a is relatively small in depth, there is less space for arranging components. If components such as batteries are to be arranged, the host 10 may be thickened at the position corresponding to the first cavity 120a. This embodiment will be described below by taking the circuit board and the speaker both arranged in the second cavity 121a as an example.

[0143] In some embodiments, when the circuit board and the speaker are both arranged in the second cavity 121a, the circuit board and the speaker are stacked in sequence along the direction from the first surface 10a to the second surface 10b, that is, in the thickness direction of the host 10, the speaker is stacked on the circuit board. In this way, on the one hand, it is convenient to connect the speaker to the circuit board, and on the other hand, the speaker is closer to the second surface 10b, which is more conducive to sound production.

[0144] Furthermore, a plurality of sound holes 1013 may be provided at positions of the second surface 10b corresponding to the second cavity 121a, and the plurality of sound holes 1013 may be used for the speaker to emit sound. At the same time, at least one convex point 1014 may be provided at positions of the second surface 10b corresponding to the second cavity 121a, and the convex point 1014 may protrude from the second surface 10b. In this way, when the user turns the scanning pen 01 upside down on the desktop, for example, places the second surface 10b on the desktop, and the display screen 30 faces the user, the sound hole 1013 will be blocked by the desktop, thus affecting the sound effect of the speaker. Based on this, the setting of the convex point 1014 can maintain a certain gap between the second surface 10b and the desktop, avoiding the situation where the sound hole 1013 is completely attached to the desktop and blocked, affecting the sound.

[0145] Exemplarily, the number of protrusions 1014 can be two, symmetrically arranged along the width direction Y of the host 10, and the protrusions 1014 can be close to the edge of the second surface 10b along the width direction Y, so that the protrusions 1014 provide more uniform support for the second surface 10b.

[0146] It should be noted that the above-mentioned protrusions 1014 do not only indicate that the structure is a point. Small columnar structures, block structures, strip structures, etc., as long as they are designed to protrude from the second surface 10b, are within the scope of the above-mentioned protrusions 1014 of the present application.

[0147] In actual settings, a position on the second surface 10b corresponding to the second cavity 121a may be provided with a sinking groove 1015 that sinks toward the first surface 10a, and the host housing 11 may also include a decorative sheet 122, which may be installed in the sinking groove 1015. The decorative sheet 122 may be provided with the above-mentioned multiple sound outlet holes 1013, and the protrusions 1014 on the second surface 10b may be close to the periphery of the decorative sheet 122 along the length direction X. By adding the sinking groove 1015 on the second surface 10b to set the decorative sheet 122, the decorative sheet 122 can play a decorative role on the second housing 102, so that the overall appearance of the host 10 is better. At the same time, the decorative sheet 122 can be made of a material different from that of the second housing 102, for example, a material with a harderness greater than that of the second housing 102, such as a metal sheet, so as to effectively improve the structural strength of the second housing 102 at the sound outlet hole 1013.

[0148] In some embodiments, as can be seen from the foregoing, the circuit board and the speaker can be disposed in the second cavity 121a of the host 10. Considering that the scanning housing 21 can be held, a battery 500 (see Fig.11 In this case, the battery can be connected to the rotating shaft assembly 100 (see Fig.12 ) is routed to the second cavity 121a and electrically connected to the circuit board. Specifically, the shaft assembly 100 may be at least partially hollow, so that the battery 500 can be routed through the hollow portion of the shaft assembly 100 to the host cavity 12 and connected to the circuit board. In this way, by arranging the battery 500 in the scanning housing 21, not only can the battery 500 be used to counterweight the scanning housing 21 without adding an additional counterweight, but also the internal space of the scanning housing 21 can be used to reasonably arrange the battery 500, so that more space in the host cavity 12 can be used to arrange other devices.

[0149] In some other embodiments, batteries may be provided in both the host 10 and the scanning housing 21. Specifically, the first cavity 120a and / or the second cavity 121a may be provided with a first battery, which is connected to the circuit board, and the scanning housing 21 may be provided with a second battery. The shaft assembly 100 is partially hollow, and the second battery may be routed through the hollow portion of the shaft assembly 100 to the host cavity 12 and connected to the circuit board. In other words, in this way, batteries may be provided in both the host 10 and the scanning housing 21, respectively, and a dual-battery design is adopted. The second battery in the scanning housing 21 can not only play a counterweight role, but also power the scanning module 23, while the first battery in the first cavity 120a and / or the second cavity 121a can power the speaker and the circuit board. In this way, different batteries power different components, thereby improving the endurance of the scanning pen 01.

[0150] Of course, it is understandable that in the above-mentioned dual-battery solution, the second battery may not be routed to the host cavity 12 to be electrically connected to the circuit board, but an additional circuit board may be directly added in the scanning shell 21, that is, the host 10 is arranged with a first battery, a first circuit board and a speaker, and the scanning shell 21 is arranged with a second battery, a second circuit board and a scanning module 23. This is more conducive to the wiring design of the second battery and the scanning module 23 in the scanning shell 21, and the wiring design is simpler. Since the line does not need to be routed through the shaft assembly 100, the scanning shell 21 and the host 10 can be sealed separately, which is beneficial to the waterproof design of the scanning pen 01.

[0151] In addition, it should be noted that in the above-mentioned dual-battery design, the first battery can be arranged in the first cavity 120a, or in the second cavity 121a, or a part of it can be arranged in the first cavity 120a, and the other part can be arranged in the second cavity 121a. Specifically, the setting can be adjusted while taking into account the thickness of the host 10 and the internal space of the first cavity 120a and the second cavity 121a. This embodiment does not make any specific limitation on this.

[0152] This embodiment will take the scanning pen 01 having a single battery, and the battery is arranged in the scanning shell 21, and is routed to the host cavity 12 through the shaft assembly 100 to be electrically connected to the circuit board as an example, and then introduce how the shaft assembly 100 realizes the routing of the two.

[0153] Please read together Fig.11 and Fig.12 The scanning housing 21 may have a scanning cavity 22, and the scanning module 23 and the battery 500 may be disposed in the scanning cavity 22. The rotating shaft assembly 100 may include a first rotating shaft 110 and a second rotating shaft 120 located on the aa axis. The first rotating shaft 110 and the second rotating shaft 120 may be installed in the scanning cavity 22 and located at both ends of the scanning cavity 22 along the aa axis, so that the host housing 11 and one end of the scanning housing 21 may be hinged through the first rotating shaft 110 and the second rotating shaft 120. Thus, the host 10 and the scanning assembly 20 may rotate relative to each other around the rotating shaft assembly 100.

[0154] Furthermore, the scanning pen 01 may further include a first wire 200, and the battery in the scanning housing 21 and the circuit board in the host 10 may be electrically connected via the first wire 200. Fig.12 and Fig.13As shown, the first rotating shaft 110 and the second rotating shaft 120 may be spaced apart to form a wire cavity 130 located between the first rotating shaft 110 and the second rotating shaft 120. The sleeve 122 may have a wire hole 121, and the wire hole 121 may pass through both ends of the second rotating shaft 120 along the axial direction of the second rotating shaft 120. In addition, one end of the wire hole 121 may be connected to the scanning cavity 22 through the wire cavity 130, and the other end of the wire hole 121 may be connected to the host cavity 12. In this way, the first wire 200 can be passed through the wire hole 121 and passed through the host cavity 12 and the scanning cavity 22, thereby realizing the electrical connection between the battery in the scanning housing and the circuit board in the host.

[0155] Specifically, a partition 220 is provided in the scanning cavity 22 to separate the scanning cavity 22 into a first cavity 221 and a second cavity 222 along the length direction X of the host 10. The first rotating shaft 110 and the second rotating shaft 120 are provided in the first cavity 221, and the battery and the scanning module 23 are provided in the second cavity 222. That is, the length of the second cavity 222 is greater than the length of the first cavity 221, so that the second cavity 222 has enough space to set the battery and the scanning module 23, while the length of the first cavity 221 is smaller, and the first rotating shaft 110 and the second rotating shaft 120 can be set. In this way, by partitioning the scanning cavity 22, the various components in the scanning cavity 22 can be reasonably configured, and the components inside the scanning housing are arranged more reasonably without affecting the rotation of the first rotating shaft 110 and the second rotating shaft 120, and the space utilization rate is higher.

[0156] Furthermore, a carrier plate 220a is provided on the partition portion 220, and a connector 220b having a second wire 200a is provided on the carrier plate 220a. The flexible circuit board of the scanning module 23 extends to the carrier plate 220a to be connected to the connector 220b, and then the second wire 200a is led out from the connector 220b and passed through the wire hole 121 to be routed to the host cavity 12 and connected to the circuit board. The flexible circuit board of the scanning module 23 is led out from the second rotating shaft 120 through the second wire 200a, so as to avoid the situation where the flexible circuit board is easily broken when the second rotating shaft 120 rotates, resulting in circuit failure.

[0157] The first wire 200 of the battery is led out through the gap between the carrier plate 220a and the partition portion 220 and passed through the wire hole to be routed into the host cavity 12 and connected to the circuit board.

[0158] It can be seen that the present application can further utilize the space of the partition portion 220 through the setting of the supporting plate 220a to separate the first wire 200 of the battery and the flexible circuit board of the scanning module 23 in the thickness direction of the scanning shell 21, that is, the first wire 200 of the battery is located at the bottom, and the flexible circuit board of the scanning module 23 is located at the top. In this way, the routing of the two does not interfere with each other, making the wiring in the scanning shell 21 more concise.

[0159] In some embodiments, in combination Fig.13 and Fig.14 As shown, the second rotating shaft 120 may include a sleeve 122 and a first connecting member 123 connected to each other. The first connecting member 123 may be provided at one end of the sleeve 122 for connecting to the scanning housing 21, and the other end of the sleeve 122 may be rotatably connected to the host housing 11. Of course, the second rotating shaft 120 may also be directly bonded or integrally formed with the scanning housing 21 as a separate part. The embodiment of the present application does not impose any special restrictions on the specific structure of the second rotating shaft 120 and the connection method between the second rotating shaft 120 and the scanning housing 21.

[0160] In addition, according to the different structural shapes of the host housing 11 and the scanning housing 21, the first rotating shaft 110 and the second rotating shaft 120 can also be installed in the host cavity 12. The embodiment of the present application does not impose any special restrictions on the specific location where the rotating shaft assembly 100 is installed. The second rotating shaft 120 can also use a hollow shaft tube structure, the shaft tube has a lumen, and a window for the wire 200 to pass through is opened on the shaft tube, the lumen is connected to the window, and the function of electrically connecting the host 10 and the scanning assembly 20 can also be realized. The embodiment of the present application does not impose any special restrictions on the structural form of the second rotating shaft 120.

[0161] When the scanning pen 01 is in a folded or unfolded state, in order to keep the scanning component 20 in the folded or unfolded position, a certain holding force needs to be provided to the scanning component 20. The holding force means that the scanning component 20 can maintain the folded or unfolded state relative to the host 10 without the action of external force; when a certain force is applied to the scanning component 20, the folded or unfolded state relative to the host 10 can be changed.

[0162] In order to provide the above-mentioned holding force, such as Fig.14 As shown, the shaft assembly 100 may further include a damping structure 140. The damping structure 140 may be mounted on the first shaft 110, and the damping structure 140 provides a holding force between the host 10 and the scanning assembly 20. Exemplarily, the damping structure 140 may include, but is not limited to, a damping washer or a cam structure. Taking a damping washer as an example, the damping washer may be mounted on the first shaft, so that during the rotation process, the inner surface of the damping washer and the outer surface of the first shaft 110 rub against each other, thereby providing a damping effect.

[0163] Combination Fig.15 As shown, Fig.15 1 is a schematic diagram of the scanning component 20 of the present application rotating relative to the host 10 to form a support state. In some embodiments, the scanning component 20 may also have a support state, and the support state may be located between the storage state and the unfolded state, so that the damping structure 140 may also be configured to provide a force to the scanning component 20 to maintain the support state. Among them, the support state refers to the state in which the scanning component 20 forms an angle α relative to the host 10, and the angle α is 0°-90°. At this time, the scanning component 20 can form the above-mentioned angle α relative to the host 10, so that the user can use the scanning component 20 as a support frame when the scanning function is not needed, so that the scanning component 20 can support the host 10 and place it on a placement surface (such as a desktop, countertop, etc.), without the user holding the host 10, which is convenient for the user to watch videos or operate the display screen 30.

[0164] In addition, using the scanning component 20 as a support frame is equivalent to structural reuse of the scanning component 20. There is no need to add additional bracket parts to the scanning pen 01. The structure is simpler, and the structural reuse can be called at any time according to user needs, which is more convenient to use.

[0165] It is understandable that the above angle can be further 0°-45°, for example, 5°, 10°, 15°, 18°, 20°, 25°, 30°, 35°, 40°, 45°, etc. This is because, as can be seen from the above, the host 10 is roughly rectangular, and in order to facilitate users to watch videos, the display screen 30 of the host 10 can usually be placed on the desktop in a horizontal screen display mode. Therefore, in the case of horizontal screen display, the angle cannot be too large. If the angle is too large, the display screen 30 will be roughly vertical or tilted forward relative to the desktop, which is not conducive to users viewing and operating the display screen 30. Based on this, within the above angle range, the angle between the display screen 30 and the desktop can be made appropriate, which is convenient for users to view and operate the display screen 30.

[0166] Furthermore, the scanning component 20 has the above-mentioned storage state, support state and unfolded state. Considering that the maintenance between the various states is mainly achieved by the damping structure 140, when the scanning component 20 is in the storage state, in order to make the scanning component 20 relatively stable in the storage state relative to the host 10 to avoid shaking, the scanning pen 01 can also add a locking structure design, that is, the locking structure is used to further maintain the scanning component 20 in the storage state. Specifically, when the locking structure is in the locking state, the locking structure can lock the scanning component 20 with the host 10 to keep the scanning component 20 in the storage state, and the damping structure 140 has a retaining force applied to the scanning component 20 to rotate away from the host 10. In this way, when the locking structure is in the locking state, the scanning component 20 can be bounced relative to the host 10 under the action of the damping structure 140 to switch to the support state. In other words, once the locking structure is unlocked, the scanning component 20 can automatically spring open relative to the host 10 under the action of the damping structure 140 and directly switch to the bracket state. In this way, the user does not need to manually pry open the scanning component 20, which is more convenient to use and more automated.

[0167] It should be noted that when the scanning component 20 pops open relative to the host 10 and directly switches to the bracket state, at this time, if the user wants to use the scanning function, the scanning component 20 can be manually rotated to unfold it relative to the host 10 to achieve normal scanning function.

[0168] Optionally, the locking structure mentioned above may include but is not limited to a button structure, a magnetic structure, etc., and when the locking structure is a button structure, the pressing portion of the locking structure may be located on the side wall of the host 10 or the surface of the host 10 facing away from the display screen 30 (i.e., the second surface 10b). The specific setting can be based on actual conditions. The specific setting structure and setting position of the locking structure will be explained in detail below and will not be discussed here.

[0169] In some embodiments, considering that the scanning component 20 has the above-mentioned multiple different states, in order to enable the scanning pen 01 to quickly enter different working states according to the different states of the scanning component 20, the scanning pen 01 may also include an angle detection component 40, which may be provided on the host 10 and the scanning component 20, and is used to detect the rotation angle of the scanning component 20 relative to the host 10 and output the detection result, so that the circuit board of the scanning pen 01 can control the scanning pen 01 to enter the corresponding working mode according to the detection result output by the angle detection component 40. In this way, the corresponding working mode can be automatically entered according to the rotation angle without manual operation by the user, which has a higher degree of automation and is more convenient for users to use.

[0170] For example, the working mode may include at least a first working mode, a second working mode and a third working mode, wherein the first working mode may be, for example, a standby mode, the second working mode may be, for example, a video display mode, and the third working mode may be, for example, a scanning mode. When the scanning component 20 is in the storage state, the circuit board may control the scanning pen 01 to enter the first working mode; when the scanning component 20 is in the unfolded state, the circuit board may control the scanning pen 01 to enter the second working mode; when the scanning component 20 is in the bracket state, the circuit board may control the scanning pen 01 to enter the third working mode. In the first working mode, the scanning module 23 is not started, and in the second working mode, the scanning module 23 is started. And, in the third working mode, the display screen 30 starts the video display function, at which time, the scanning module 23 is not started.

[0171] That is to say, when the scanning pen 01 enters the first working mode, the scanning module 23 is automatically turned off, and the display screen 30 can be turned on or off. For example, the display screen 30 can be turned off. At this time, the scanning pen 01 is in an overall standby mode, which can be determined according to user needs. For example, the user can choose to use the display screen 30 or not according to actual conditions.

[0172] When the scanning pen 01 enters the second working mode, the scanning module 23 and the display screen 30 can be automatically turned on. That is to say, once the scanning module 23 is unfolded relative to the display screen 30, the scanning module 23 and the display screen 30 can be automatically started. At this time, the user only needs to aim the scanning component 20 at the scanned object to realize the scanning function and view the scanning results on the display screen 30. That is, in the second working mode, the scanning pen 01 enters the scanning mode.

[0173] When the scanning pen 01 enters the third working mode, the scanning module 23 can be automatically closed, and the display screen 30 automatically starts the video display function. That is, when the locking structure is in the unlocked state, the scanning component 20 automatically opens to form the above-mentioned angle α with the host 10 under the action of the damping structure 140. At this time, the display screen 30 can automatically start the video display function. The user only needs to support the host 10 on the desktop through the scanning component 20 to watch the video without manual operation. That is, in the third working mode, the scanning pen 01 enters the video display mode.

[0174] It can be seen that, through the setting of the angle detection component 40, the scanning pen 01 can be automatically controlled to automatically enter different working modes, with a higher degree of automation and more convenient operation.

[0175] Of course, it is understandable that in other embodiments, when the scanning pen 01 enters the third working mode, the display screen 30 may not be directly activated. The user may rotate and unfold the scanning component 20 relative to the host 10 to use the scanning function according to actual needs.

[0176] Optionally, the angle detection component 40 may be disposed adjacent to the first rotating shaft 110, so as to more easily detect the rotation angle of the scanning component 20 relative to the host 10. Specifically, the angle detection component 40 may include a Hall sensor 41 and a magnetic member 42 (eg, Fig.15 As shown, Fig.15 In the figure, only the dotted frame is used to simply illustrate the corresponding relationship between the Hall sensor and the magnetic member, and the specific structure and position thereof are not limited. One of the Hall sensor 41 and the magnetic member 42 can be arranged in the host 10, and the other can be arranged in the scanning housing 21. For example, considering that a circuit board is arranged in the host 10, in order to facilitate wiring, the Hall sensor 41 can be arranged in the host 10, and the magnetic member 42 can be arranged in the scanning housing 21. In this way, the magnetic member 42 can not only cooperate with the Hall sensor 41 to sense the rotation angle, but also the magnetic member 42 can counterweight the scanning housing 21.

[0177] It is understandable that in other embodiments, the angle detection component 40 may also be an ultrasonic sensor or a photoelectric sensor, etc., which can be selected according to actual conditions, as long as it can detect the rotation angle of the scanning component 20 relative to the host 10.

[0178] As can be seen from the foregoing, the rotation angle of the scanning assembly 20 relative to the host 10 is maintained mainly through the damping structure 140. The specific structure of the damping structure 140 will be described in detail below in conjunction with the accompanying drawings.

[0179] Specifically, take the damping structure 140 as a cam structure as an example. Fig.14 As shown, the damping structure 140 may include an end cam 141, a first reset member 142 and an end concave wheel 143. One of the end cam 141 and the end concave wheel 143 is connected to the host 10. The host 10 can drive the end cam 141 to rotate, and the scanning assembly 20 can drive the end concave wheel 143 to rotate. Among them, the end cam 141 and the end concave wheel 143 can be sleeved on the first rotating shaft 110, and the end cam 141 and the end concave wheel 143 are arranged facing each other. The first reset member 142 is arranged on the first rotating shaft 110 and presses the end cam 141 and the end concave wheel 143 in the axial direction of the first rotating shaft 110, that is, the end cam 141 and the end concave wheel 143 can be pressed by the first reset member 142 to provide the holding force of the damping structure 140. Specifically, in an actual setting, along the axial direction of the first rotating shaft 110 , the end surface concave wheel 143 , the end surface concave wheel 143 and the first restoring member 142 are arranged in sequence.

[0180] In some embodiments, Fig.14As shown, the shaft assembly 100 may further include a retaining ring 111, a second connecting member 144, and a stopper 145. The retaining ring 111 may be connected to an end position away from the first shaft 110 to expose a portion of the first shaft 110. In this way, when the first shaft 110 is installed, the retaining ring 111 may abut against the inner side of the scanning housing 21, and the exposed portion of the first shaft 110 may extend out of the scanning housing 21 for contact with the host housing 11 ( Fig.13 Of course, the first rotating shaft 110 can also be directly fixedly connected to the host 10. The embodiment of the present application does not impose any special restrictions on the connection method between the first rotating shaft 110 and the host 10.

[0181] The cross section of the first rotating shaft 110 (perpendicular to the axial direction of the first rotating shaft 110) may be a non-circular shape such as a waist shape, a rectangle, a triangle or other polygonal shape. When the first rotating shaft 110 is connected to the host 10, the host 10 can drive the first rotating shaft 110 to rotate. The end face cam 141 may have a hole of the same shape as the cross section of the first rotating shaft 110, and the end face cam 141 may be slidably connected to the first rotating shaft 110 along the axial direction of the first rotating shaft 110. In this way, along the circumference of the first rotating shaft 110, the end face cam 141 can be relatively fixed with the first rotating shaft 110, so that the host 10 can drive the end face cam 141 to rotate.

[0182] Please continue to see Fig.14 , the second connecting member 144 can be connected to the end face cam wheel 143, and the second connecting member 144 can be connected to the scanning housing 21 through a connecting structure such as screws or rivets, so that the scanning assembly 20 can drive the end face cam wheel 143 to rotate. The stopper 145 can be fixedly connected to one end of the first rotating shaft 110, and the first reset member 142 can be sleeved on the first rotating shaft 110 and located between the end face cam 141 and the stopper 145. In this way, the end face cam 141 can slide on the first rotating shaft 110 under the elastic action of the first reset member 142. Among them, the first reset member 142 can be selected from springs, springs, disc springs and other components, and the embodiment of the present application does not impose any special restrictions on the specific structure of the first reset member 142.

[0183] Among them, Fig.14 As shown, the end face cam 143 can be provided with a circular hole so that the first rotating shaft 110 can rotate in the hole of the end face cam 143, and the end face cam 143 can be arranged between the end face cam 141 and the retaining ring 111, so that the end face cam 141 is in contact with the end face cam 143 through the first reset member 142.

[0184] To provide a holding force for the scanning assembly 20, please combine Fig.14 , Fig.16 and Fig.17As shown, the end face cam 141 may include a first protrusion 1411. The end face concave wheel 143 may include a plurality of second protrusions 1431, and a plurality of grooves 1432 may be formed between adjacent second protrusions 1431. The plurality of grooves 1432 may include a first groove 1432a and a second groove 1432b. The groove 1432 may have a groove wall 1433 and a groove bottom 1434. The first protrusion 1411 and the groove wall 1433 respectively have a slope for a smooth transition. In this way, at the first reset member 142 ( Fig.14 As shown in the figure, under the pushing action of the first protrusion 1411 and the groove wall 1433, and the first protrusion 1411 is not in contact with the groove bottom 1434, the first protrusion 1411 has a tendency to move toward the groove bottom 1434, and this movement tendency can provide a holding force for the scanning component 20.

[0185] Furthermore, it can be known from the foregoing that the scanning component 20 also has a support state relative to the host 10. Based on this, the first protrusion 1411 and the second protrusion 1431 can cooperate with each other so that the scanning component can be rotated to any angle relative to the host and maintained at this angle. Of course, the end face cam 141 can also be provided with multiple first protrusions 1411, and the end face concave wheel 143 can also be provided with a greater number of grooves 1432 to form adjustable gears under different support states. In this way, the user can adjust the support states of multiple angles α, so that the scanning pen 01 can have a support display effect with different angles. The embodiment of the present application does not impose any special restrictions on the number of gears of the scanning component 20 rotation.

[0186] Specifically, if Fig.18 As shown, the end face cam 141 may have a first shaft hole 1410, and the first protrusion 1411 may be multiple. For the convenience of distinction, the multiple first protrusions 1411 may include a first outer protrusion 14111 and a second inner protrusion 14112. In other words, the end face cam 141 may include two first protrusions 1411, which are the first outer protrusion 14111 and the second inner protrusion 14112 mentioned above. The first outer protrusion 14111 and the second inner protrusion 14112 are respectively arranged on both sides of the first shaft hole 1410, and the first outer protrusion 14111 is far away from the first shaft hole 1410, and the second inner protrusion 14112 is close to the first shaft hole 1410.

[0187] Correspondingly, such as Fig.19As shown, the end face cam 143 may have a second shaft hole 1430. For the sake of distinction, the plurality of second protrusions 1431 may include a third outer protrusion 14311, a fourth outer protrusion 14312, a third inner protrusion 14313, and a fourth inner protrusion 14314. That is, at this time, the second protrusion 1431 may be four, and the four second protrusions 1431 are respectively the third outer protrusion 14311, the fourth outer protrusion 14312, the third inner protrusion 14313, and the fourth inner protrusion 14314. The third outer protrusion 14311 and the fourth inner protrusion 14314 are respectively arranged on both sides of the second axial hole 1430, the fourth outer protrusion 14312 and the third inner protrusion 14313 are respectively arranged on both sides of the second axial hole 1430, the third outer protrusion 14311 and the fourth outer protrusion 14312 are far away from the second axial hole 1430, and the third inner protrusion 14313 and the fourth inner protrusion 14314 are close to the second axial hole 1430.

[0188] In addition, both ends of the third outer protrusion 14311 and the third inner protrusion 14313 have a slope, a first central angle A is formed between the bottom of the slope of the third outer protrusion 14311 and the corresponding bottom of the slope of the third inner protrusion 14313, a second central angle B is formed between the top of the slope of the third outer protrusion 14311 and the corresponding top of the slope of the third inner protrusion 14313, and the first central angle A is equal to the second central angle B. At the same time, both ends of the fourth outer protrusion 14312 and the fourth inner protrusion 14314 have a slope, a third central angle C is formed between the bottom of the slope of the fourth outer protrusion 14312 and the corresponding bottom of the slope of the fourth inner protrusion 14314, a fourth central angle D is formed between the top of the slope of the fourth outer protrusion 14312 and the corresponding top of the slope of the fourth inner protrusion 14314, and the third central angle C is equal to the fourth central angle D. Here, corresponding refers to the slope surface at the same end of the third outer protrusion 14311 and the third inner protrusion 14313 , and the slope surface at the same end of the fourth outer protrusion 14312 and the fourth inner protrusion 14314 .

[0189] The following embodiments will be combined with Figure 20 to Figure 23 As shown in FIG. 1 , the damping structure 140 of the scanning assembly 20 in each state is described in detail. Fig. 20As shown, when the scanning component 20 is in the storage state, the slope of one end of the first outer protrusion 14111 can abut against the slope of the fourth outer protrusion 14312. At the same time, the slope of one end of the second inner protrusion 14112 also abuts against the slope of the third inner protrusion 14313. As can be seen from the above, the scanning pen 01 also includes a locking structure (the locking structure will be described in detail in the subsequent embodiments), so that the scanning component 20 can be locked on the host 10 to maintain the storage state of the scanning component 20. However, since in the storage state, the first protrusion 1411 has a tendency to move toward the groove bottom 1434 of the first groove 1432a, so as to apply a holding force to the scanning component 20 to rotate away from the host 10, the scanning component 20 has a tendency to pop out away from the host 10.

[0190] When the locking structure is unlocked, Fig.21 As shown, the first outer protrusion 14111 and the second inner protrusion 14112 move and abut against the groove bottom 1434 of the first groove 1432a under the elastic pushing force of the first restoring member 142. At this time, the scanning component 20 and the host 10 maintain an angle α (for example, 18°), so that the scanning component 20 is suspended at the angle α, so that the scanning component 20 can be used as a bracket of the host 10, so that the user can watch videos.

[0191] When the user needs to use the scanning function, such as Fig. 22 As shown, the scanning component 20 can continue to rotate. At this time, the first outer protrusion 14111 is in contact with the slope of the third outer protrusion 14311. The slope of the other end of the first outer protrusion 14111 needs to overcome the slope resistance of one end of the third outer protrusion 14311 to climb the slope. At this time, the scanning component 20 and the host 10 are at an angle of 18°-55°. As the rotation proceeds, the top of the slope of the first outer protrusion 14111 reaches the top of the slope of the third outer protrusion 14311, and the first outer protrusion 14111 and the third outer protrusion 14311 rub against each other. At this time, the scanning component 20 and the host 10 are at an angle of 55°-150°.

[0192] As the rotation continues, Fig.23As shown, the first outer protrusion 14111 enters the second groove 1432b, and the scanning assembly 20 and the host 10 are already unfolded to a state of 180°, and the scanning assembly 20 cannot be rotated further. However, at this time, the slope of the first outer protrusion 14111 abuts against the slope of the third outer protrusion 14311, and the first outer protrusion 14111 does not contact the groove bottom 1434 of the second groove 1432b, so that the first outer protrusion 14111 has a tendency to move toward the groove bottom 1434 of the second groove 1432b, thereby providing a holding force when the scanning assembly 20 is suspended in the unfolded state. At the same time, the slope of the other end of the second inner protrusion 14112 also needs to overcome the slope resistance of one end of the fourth inner protrusion 14314 to climb the slope. Until the slope of the second inner protrusion 14112 reaches the slope of the other end of the fourth inner protrusion 14314, and the second inner protrusion 14112 does not contact the bottom 1434 of the second groove 1432b, the second inner protrusion 14112 also has a tendency to move toward the bottom 1434 of the second groove 1432b, thereby providing a retaining force when the scanning component 20 is hovering in the unfolded state.

[0193] It can be seen that the first outer protrusion 14111 and the second inner protrusion 14112 of the embodiment of the present application form a group of inner and outer double-layer cam components (based on the relative position relationship of the first shaft hole 1410 mentioned above, the side close to the first shaft hole 1410 is the inner side, and the side away from the first shaft hole 1410 is the outer side), the third outer protrusion 14311 and the fourth inner protrusion 14314 form a group of inner and outer double-layer cam components, and the fourth outer protrusion 14312 and the third inner protrusion 14313 form a group of inner and outer double-layer cam components (similarly, the inner and outer are also based on the relative position of the second shaft hole 1430, the side close to the second shaft hole 1430 is the inner side, and the side away from the second shaft hole 1430 is the outer side). Through the inner and outer double-layer cam structure, the inner protrusion can be asymmetrical with the outer protrusion about the center of the cam. In this way, the inner and outer protrusions can be flexibly arranged along the circumference of the cam according to the different hovering angle designs and holding force sizes of the scanning component 20 (i.e., the different angle designs of the first central angle A, the second central angle B, the third central angle C, and the fourth central angle D in the above embodiment), so that the holding force of the scanning component 20 at different hovering angles can be different.

[0194] For example, the angle α of the scanning component 20 when in the bracket state can be designed to be 18°, that is, when the first outer protrusion 14111 contacts the groove bottom 1434 of the first groove 1432a, the scanning component 20 and the host 10 are in an 18° state. At this time, the first center angle A, the second center angle B, the third center angle C, and the fourth center angle D can be set to 15°. When the scanning component 20 is in the unfolded state, the scanning component 20 can have a 3° holding force relative to the host 10. Of course, the first center angle A, the second center angle B, the third center angle C, and the fourth center angle D can also be set to 10°, 20°, or other degrees, so that when the scanning component 20 is in the unfolded state, the scanning component 20 can have different degrees of holding force relative to the host 10. The embodiment of the present application does not impose any special restrictions on the specific holding force design between the scanning component 20 and the host 10.

[0195] In addition, the first protrusion 1411 and the second protrusion 1431 are respectively arranged in the form of inner and outer double-layer cam structures, which can increase the friction area between the end face cam 141 and the end face concave wheel 143. Since the friction force of the end face cam 141 and the end face concave wheel 143 rotating under the push of the first reset member 142 is fixed, increasing the friction area is conducive to reducing the wear between the end face cam 141 and the end face concave wheel 143, thereby increasing the service life of the shaft assembly 100.

[0196] In the above embodiment, the first protrusion 1411 and the second protrusion 1431 may have different slopes, and different slopes may adjust the torque between the end cam 141 and the end concave wheel 143 during rotation. When the slope is larger, the torque required between the end cam 141 and the end concave wheel 143 is also larger. Conversely, when the slope is smaller, the torque required between the end cam 141 and the end concave wheel 143 is also smaller.

[0197] In more embodiments, such as Fig.18 As shown, the first protrusion 1411 may be more, that is, in addition to the first outer protrusion and the second inner protrusion mentioned above, for the convenience of distinction, it may also include a second outer protrusion 14113 and a first inner protrusion 14114. The second outer protrusion 14113 and the first inner protrusion 14114 are respectively arranged on both sides of the first shaft hole 1410, and the second outer protrusion 14113 is far away from the first shaft hole 1410, and the first inner protrusion 14114 is close to the first shaft hole 1410. That is, at this time, the first protrusion 1411 includes four, and the four first protrusions 1411 are respectively the first outer protrusion 14111, the second inner protrusion 14112, the second outer protrusion 14113 and the first inner protrusion 14114 mentioned above.

[0198] In addition, the top of the first outer protrusion 14111 is flush with the top of the first inner protrusion 14114, and during the relative rotation of the end face cam 141 and the end face concave wheel 143, the end face concave wheel 143 only contacts the top of the first inner protrusion 14114. Similarly, the top of the second outer protrusion 14113 is flush with the top of the second inner protrusion 14112, and during the relative rotation of the end face cam 141 and the end face concave wheel 143, the end face concave wheel 143 only contacts the top of the second outer protrusion 14113.

[0199] During the relative rotation of the end face cam 141 and the end face concave wheel 143, the two ends of the second outer protrusion 14113 and the first inner protrusion 14114 do not contact the two ends of the second protrusion 1431. The arrangement of the second outer protrusion 14113 and the first inner protrusion 14114 can increase the friction area between the end face cam 141 and the end face concave wheel 143, thereby reducing the wear between the end face cam 141 and the end face concave wheel 143. In addition, the second outer protrusion 14113 can support the second inner protrusion 14112, and the first inner protrusion 14114 can also support the first outer protrusion 14111, thereby increasing the service life of the end face cam 141.

[0200] The above embodiment is an introduction to the structure of the rotating shaft assembly 100 that has a tendency to rotate away from the host 10 when the scanning assembly 20 is in the stored state. In other embodiments, the scanning assembly 20 may also have a tendency to rotate toward the host 10 when in the stored state to prevent the scanning assembly 20 from easily separating from the host 10 when in the folded state. Fig.24 and Fig.25 As shown, the end face cam 141 may include a third protrusion 1412. The end face concave wheel 143 may include a plurality of fourth protrusions 1435, and a third groove 1432c and a fourth groove 1432d may be formed between adjacent fourth protrusions 1431. The third protrusion 1412 may also have the first outer protrusion 14111 in the above embodiment, and the fourth protrusion 1435 may also have the third outer protrusion 14311 and the fourth outer protrusion 14312 in the above embodiment. The remaining structures of the third protrusion 1412 and the fourth protrusion 1435 may also be the same as the structure of the shaft assembly 100 in the above embodiment, and will not be repeated here.

[0201] When the scanning assembly 20 is in the storage state, the slope of the first outer protrusion 14111 may not abut against the slope of the fourth outer protrusion 14312, but the slope of the first outer protrusion 14111 may abut against the slope of the third outer protrusion 14311, and the third protrusion 1412 does not contact the groove bottom 1434 of the third groove 1432c. At this time, the scanning assembly 20 has a tendency to rotate toward the host 10, that is, the scanning assembly 20 has a holding force with the host 10 to prevent the scanning assembly 20 from being easily separated from the host 10 when in the folded state.

[0202] When the user needs to scan, the scanning component 20 can be rotated in the direction away from the host 10. In this process, the user applies a rotational force to the scanning component 20, so that the third protrusion 1412 enters the fourth groove 1432d. Similarly, the third protrusion 1412 first fits into the groove wall 1433 of the fourth groove 1432d, and the third protrusion 1412 does not contact the groove bottom 1434 of the fourth groove 1432d, so that the scanning component 20 still has a tendency to rotate in the direction away from the host 10. However, at this time, the scanning component 20 is already in a 180° unfolded state with the host 10, so the third protrusion 1412 cooperates with the groove wall 1433 of the fourth groove 1432d, which can also provide a holding force for the scanning component 20 in the unfolded state to prevent the host 10 from shaking during the scanning process.

[0203] Of course, the first protrusion 1411 or the third protrusion 1412 can also be arranged on the end face concave wheel 143, and the groove 1432 can also be arranged on the end face cam 141. In addition, according to the different positions where the scanning component 20 needs to hover, a plurality of grooves 1432 can be arranged on the end face concave wheel 143. When the first protrusion 1411 or the third protrusion 1412 on the end face cam 141 is embedded in the grooves 1432 at different positions, the scanning component 20 can also hover at different positions of the host 10 for the convenience of the user. The embodiment of the present application does not impose any special restrictions on the specific positions and specific numbers of the first protrusion 1411, the third protrusion 1412 and the groove 1432.

[0204] The above embodiment is a detailed introduction to the specific structure of the shaft assembly 100. The host 10 and the scanning assembly 20 can not only rotate with each other through the shaft assembly 100, but also keep the host 10 and the scanning assembly 20 in a fixed position of folding or unfolding through the shaft assembly 100. Of course, other locking structures can also be used to achieve the function of keeping the host 10 and the scanning assembly 20 in a fixed position. The following embodiment will introduce the locking structure in detail.

[0205] See also Figure 26 to Figure 29Before introducing the locking structure, in some embodiments, it is considered that the scanning assembly 20 of the present application can rotate relative to the host 10, and a receiving groove 11c is provided on the second surface 10b of the host 10 to receive the scanning assembly 20. Based on this, in order to provide positioning for the scanning assembly 20 when it is received in the receiving groove 11c, a convex portion 103 may be convexly provided on the groove bottom surface 11a of the receiving groove 11c. The scanning end of the scanning assembly 20 has a notch 202, and the scanning window 201 of the scanning assembly 20 is located in the notch 202. Since the convex portion 103 is provided on the groove bottom surface 11a of the receiving groove 11c, and the scanning assembly 20 is received in the receiving groove 11c in the receiving state, when the scanning assembly 20 is in the receiving state, the convex portion 103 may be provided corresponding to the notch 202 and at least partially located in the notch 202, that is, the convex portion 103 may be at least partially embedded in the notch 202. In this way, when the user stores the scanning component 20, the user can rotate the scanning component 20 according to the position of the protrusion 103 so that the notch 202 of the scanning component 20 gradually approaches the storage slot 11c of the main unit 10, and finally aligns it to the position of the protrusion 103, so that the protrusion 103 is at least partially embedded in the notch 202. At this time, it can be considered that the scanning component 20 has been stored in place relative to the storage slot 11c.

[0206] It is understandable that when the convex portion 103 is embedded in the notch 202, the convex portion 103 may not contact the scanning window 201 to avoid the contact between the two and damage to the scanning window 201. Of course, as another example, the convex portion 103 may also contact the scanning window 201. In this case, in order to avoid damage to the scanning window 201, the convex portion 103 may be made of a material such as soft plastic or rubber.

[0207] See also Figure 26 to Figure 29 In other embodiments, in order to maintain the storage state between the host 10 and the scanning component 20, it can be known from the above that the locking structure 60 can be used to achieve this. Specifically, considering that the locking structure 60 is mainly used to lock the scanning component 20 and the host 10 when in the locked state, and the scanning component 20 is mainly stored in the storage groove 11c when in the storage state. Based on this, the storage groove 11c can have a groove bottom surface 11a, and the groove bottom surface 11a of the storage groove 11c is convexly provided with a convex portion 103, then the locking structure 60 can be at least partially located in the convex portion 103, and then the convex portion 103 can be used to cover at least part of the locking structure 60, so that the scanning component 20 and the host 10 are in the locked state. The locking structure 60 is not visible from the appearance of the scanning pen 01, or only a part of the locking structure 60 can be seen, thereby making the overall appearance of the scanning pen 01 more concise.

[0208] Furthermore, the scanning end of the scanning component 20 has a notch 202, and the scanning window 201 of the scanning component 20 is located in the notch 202. Since the convex portion 103 is provided on the groove bottom surface 11a of the receiving groove 11c, and the scanning component 20 is received in the receiving groove 11c when in the received state, when the scanning component 20 is in the received state, the convex portion 103 can be provided corresponding to the notch 202 and at least partially located in the notch 202, that is, the convex portion 103 can be at least partially embedded in the notch 202. In this way, the convex portion 103 can just utilize the position of the notch 202 to achieve shielding of the locking structure 60.

[0209] Furthermore, the convex portion 103 is formed with a recessed portion 1032 on one side of the groove bottom surface 11a facing away from the receiving groove 11c, so that the locking structure 60 can be at least partially located in the recessed portion 1032. In other words, the locking structure 60 can be mostly located in the recessed portion 1032, or only a small part can be located in the recessed portion 1032. In other words, the space of the recessed portion 1032 is used to set the locking structure 60, which saves the internal space of the host 10 on the one hand, and can effectively cover the locking structure 60 on the other hand.

[0210] As can be seen from the foregoing, the locking structure 60 may include at least one of a button structure and a magnetic structure. This embodiment will be described by taking the locking structure 60 as a button structure as an example.

[0211] In some embodiments, the convex portion 103 is provided with a first latch hole (not shown), the first latch hole can be connected to the concave portion 1032, the locking structure 60 can include a locking portion 63, and the scanning housing 21 is correspondingly provided with a second latch hole 20b. When the locking structure 60 is in a locked state, the locking portion 63 extends through the first latch hole and connects with the second latch hole 20b, so that the scanning component 20 is kept in the storage state. When the locking structure 60 is in an unlocked state, the locking portion 63 retracts into the first latch hole to separate from the second latch hole 20b, so that the scanning component 20 is released from the storage state. In this way, by using the first latch hole on the convex portion 103, the locking portion 63 can be extended to connect with the scanning component 20, or be disconnected from the scanning component 20. The structure is simple, and the convex portion 103 can be used to cover the locking portion 63, so that the overall appearance of the scanning pen 01 is more concise and the structure is more compact.

[0212] Specifically, Fig. 27 and Fig.28As shown, along the width direction of the host 10, the protrusion 103 has a side 1031 facing the groove side wall of the storage groove 11c, and there is a space between the side of the protrusion 103 and the groove side wall 11b of the storage groove 11c. When the scanning component 20 is in the storage state, the scanning end of the scanning component 20 is just located in the space, and the locking portion 63 is located between the scanning component 20 and the side 1031 of the protrusion 103. That is to say, the locking structure 60 of the present application adopts a method of locking the scanning component 20 in the storage groove 11c when locking the scanning component 20 and the host 10.

[0213] On this basis, if Fig.28 and Fig.30 As shown, the locking structure 60 may further include a locking frame 61, a third reset member 62 and a pressing member 64. The locking portion 63 is arranged on the locking frame 61, one end of the pressing member 64 is arranged on the locking frame 61, the other end of the pressing member 64 extends out of the main unit 10 from the avoidance hole 10f, and the third reset member 62 is connected to the locking frame 61. When the pressing member 64 is pressed, the locking frame 61 can move along the telescopic direction of the third reset member 62 to drive the locking portion 63 to retract into the first clamping hole to separate from the second clamping hole 20b, so that the locking structure 60 is in an unlocked state; the third reset member 62 is used to make the locking frame 61 drive the locking portion 63 to extend out of the first clamping hole and connect with the second clamping hole 20b when the pressing effect of the pressing member 64 disappears, so that the locking structure 60 is in a locked state. In this way, by pressing the pressing member 64, the locked state can be effectively released, and the user operation is more convenient.

[0214] Optionally, the locking frame 61 can be set to be a C-shaped frame, so that the locking frame 61 can bypass the groove side wall 11b of the receiving groove 11c and extend to the side 1031 of the protrusion 103. The third reset member 62 can be abutted between the groove side wall 11b of the receiving groove 11c and the locking frame 61. When the scanning component 20 is in the storage state, the locking frame 61 is pressed against the housing of the host 10 under the elastic action of the third reset member 62. At this time, the locking portion 63 extends from the first clamping hole and is connected to the second clamping hole 20b on the scanning housing 21. When the scanning component 20 needs to be unfolded, the pressing member 64 can be pressed to make the locking portion 63 move away from the second clamping hole 20b along the extension direction of the third reset member 62, thereby realizing the function of unlocking the scanning component 20.

[0215] Of course, the locking structure 60 can also be arranged on the scanning component 20. Accordingly, the second latch hole 20b can be provided on the host 10, and the function of locking and unlocking the scanning component 20 can also be realized. The embodiment of the present application does not impose any special restrictions on the specific position where the locking structure 60 is installed. According to the different positions where the locking structure 60 is connected to the housing of the host 10, the locking frame 61 can also be set to a straight line, an arc or an L shape. The embodiment of the present application does not impose any special restrictions on the specific shape of the locking frame 61. In addition, the third reset member 62 can also be set to a structure such as a spring or a spring sheet.

[0216] It is understandable that the pressing member 64 can be disposed at different positions of the host 10 so as to be pressed by the user. For example, the pressing member 64 can be disposed on a side wall of the host 10, such as a side wall of the host 10 along the length direction, or the pressing member 64 can also be disposed on a side of the host 10 that is away from the display screen (i.e., the aforementioned second surface 10b). Each of these will be described below.

[0217] like Figure 26 to Figure 29 As shown, in one example, the pressing member 64 is disposed on a side wall of the main unit 10 along the length direction. Then, a avoidance hole 10f is disposed on the side wall of the main unit 10, a first clamping hole is disposed on a side of the convex portion 103 facing the side wall of the main unit 10, and an installation gap 11g is provided between the groove side wall 11b of the receiving groove 11c and the side wall of the main unit 10 (the installation gap 11g is a gap located inside the housing of the main unit 10). The locking frame 61 includes a first mounting portion 61a and a connecting portion 61b, the first mounting portion 61a is located in the mounting gap 11g, one end of the pressing member 64 is arranged on the first mounting portion 61a, the third reset member 62 abuts between the first mounting portion 61a and the side wall of the storage groove 11c, the connecting portion 61b is connected to the first mounting portion 61a, and extends in a direction away from the first mounting portion 61a to a part located in the recessed portion 1032, and the locking portion 63 is arranged at the position where the connecting portion 61b is located in the recessed portion 1032. That is to say, the locking structure 60 as a whole is roughly located at the installation gap 11g between the groove side wall 11b of the storage groove 11c and the side wall of the host 10, so that the space between the groove side wall 11b of the storage groove 11c and the side wall of the host 10 can be used, without occupying the main space of the shell of the host 10 (such as the second cavity for installing the speaker and the circuit board mentioned above), making the overall structure of the host 10 more compact, and also making the pressing stroke of the locking structure 60 shorter, making the pressing more labor-saving. The locking part 63 is arranged at the position where the connecting part 61b is located in the recessed part 1032, and the space of the recessed part 1032 can be used to set a part of the connecting part 61b and the locking part 63, so that the locking structure 60 occupies less space inside the shell of the host 10, and the overall structure of the host 10 is more compact.

[0218] Further, it can be known from the above that the locking frame 61 is generally a C-shaped frame body, based on which the first mounting portion 61a and the connecting portion 61b can enclose a mounting space 610 with an opening, the third reset member 62 can be located in the mounting space 610, and the locking portion 63 is arranged on the side of the connecting portion 61b facing the mounting space 610. In this way, the structure of the locking frame 61 can extend from the mounting gap 11g between the slot side wall of the storage slot 11c and the side wall of the host 10 to the recessed portion 1032, so that the locking portion 63 can extend from or retract from the first clamping hole. Moreover, by adopting a C-shaped frame body, the third reset member 62 and the locking portion 63 are both located in the mounting space 610 enclosed by the first mounting portion 61a and the connecting portion 61b, which can make the overall structure of the locking structure 60 more compact and occupy less space inside the host 10.

[0219] Further, considering that the first mounting portion 61a is connected to the pressing member 64, it can move along the extension direction of the third reset member 62 under the pressing action of the pressing member 64. Based on this, the first mounting portion 61a can be provided with a first guide portion 611, and the locking structure 60 can also include a first limiting bracket 65, which is connected to the installation gap 11g to limit the position of the first mounting portion 61a in the installation gap 11g, so as to prevent the locking structure 60 from being separated or displaced from the housing of the host 10 when falling or impacting, thereby affecting the locking connection with the scanning assembly 20. Specifically, the first limiting bracket 65 is provided with a second guide portion 651 corresponding to the first guide portion 611, and the second guide portion 651 is slidably connected to the first guide portion 611 along the extension direction of the third reset member 62 to guide the movement of the first mounting portion 61a along the extension direction of the third reset member 62. The first guide portion 611 may be a guide post, and the second guide portion 651 may be a guide hole, and the length direction of the guide hole is arranged along the extension direction of the third reset member 62. The guide post can slide in the guide hole, so that the locking frame 61 can move along the extension direction of the third reset member 62 through the sliding cooperation between the first guide portion 611 and the second guide portion 651. The travel of the guide hole can be greater than or equal to the pressing member 64 ( Fig.32 Of course, the first guide portion 611 may also be a guide hole, and the second guide portion 651 may also be a guide column. The embodiment of the present application does not impose any special restrictions on the specific structure and setting position of the first guide portion 611 and the second guide portion 651.

[0220] In addition, if Fig.32 and Fig.33As shown, the first guide part 611 can be multiple, and the second guide part 651 can also be multiple. For example, taking two as an example, the two first guide parts 611 can be respectively arranged on both sides of the two third reset members 62, and the two second guide parts 651 can respectively correspond to the positions of the two first guide parts 611. In this way, the two first guide parts 611 can respectively slide with the two second guide parts 651, so that the locking frame 61 can move along a straight line to avoid damage to the locking frame 61 caused by deflection. Among them, the third reset member 62 can be selected from springs, and a spring guide column can also be provided on the first mounting portion 61a. The spring can be installed on the spring guide column to guide the expansion and contraction direction of the spring.

[0221] In some embodiments, Fig.31 and Fig.32 As shown, a third guide portion 612 may be provided on the connecting portion 61b near the locking portion 63, and a fourth guide portion 1010 may be provided in the recessed portion 1032. The third guide portion 612 may be a guide groove, and the fourth guide portion 1010 may be a guide bar, and the guide groove may slide on the guide bar, so that the locking frame 61 may move along the telescopic direction of the third reset member 62 through the sliding cooperation between the third guide portion 612 and the fourth guide portion 1010. Since the third guide portion 612 and the fourth guide portion 1010 are provided at a position close to the locking portion 63, the locking portion 63 may move in a straight line, that is, the telescopic movement of the locking portion 63 may be guided. Of course, the third guide portion 612 may also be a guide bar, and the fourth guide portion 1010 may also be a guide groove. The embodiment of the present application does not impose any special restrictions on the specific structure and setting position of the third guide portion 612 and the fourth guide portion 1010.

[0222] When the third return member 62 is a spring, in some embodiments, as Fig.32 As shown, the first limiting bracket 65 may also be provided with a first limiting portion 652, which may be arranged on one radial side of the spring to limit the radial movement of the spring. The first limiting portion 652 may be bent to form a limiting groove, so that the spring may be installed in the limiting groove. The embodiment of the present application does not impose any special restrictions on the specific structure of the first limiting portion 652.

[0223] In other embodiments, Fig.33As shown, the first guide portion 611 can be a cylindrical structure arranged along the telescopic direction of the third reset member 62. In this case, there is no need to add the above-mentioned first limiting portion 652, but the first guide portion 611 can simultaneously limit the third reset member 62 and cooperate with the second guide portion 651. Specifically, one end of the third reset member 62 can be connected to the inside of the first guide portion 611 to limit the radial movement of the third reset member 62. At this time, the second guide portion 651 can be slidably matched on the outside of the first guide portion 611.

[0224] In addition, if Fig.32 As shown, since the installation gap 11g provided by the locking structure 60 is arranged close to the second cavity portion, and a speaker is arranged in the second cavity portion, based on this, a buffer is provided on the side where the first mounting portion 61a is connected to the pressing member 64, and the buffer is configured to mitigate the influence of the pressing vibration of the pressing member 64 on the speaker. Specifically, a reserved groove is provided on the side where the first mounting portion 61a is connected to the pressing member 64, and the buffer can be arranged in the reserved groove. The provision of the buffer can buffer and dampen the movement of the pressing member 64, thereby reducing the noise caused by the vibration of the pressing member 64 and the locking frame 61 when the speaker is playing. Optionally, the buffer can be made of foam or silicone pad. The embodiment of the present application does not impose any special restrictions on the specific material of the buffer.

[0225] In another example, the pressing member 64 of the locking structure 60 may be disposed on the second surface 10b of the housing of the host 10. Fig.34 and Fig.35 As shown, the second surface 10b is provided with an avoidance hole 10f, and the avoidance hole 10f is located at the periphery of the storage groove 11c. In actual settings, the avoidance hole 10f can be set at the position of the second surface 10b corresponding to the second cavity. The locking frame 61 may include a first mounting portion 61a and two spaced connecting portions 61b, the first mounting portion 61a can be straddled on the two connecting portions 61b, one end of the pressing member 64 is provided on the first mounting portion 61a, and the third reset member 62 is connected between the two connecting portions 61b, and the locking portion 63 is provided on at least one of the connecting portions 61b. In this way, the locking structure 60 can be set as a whole in the recessed portion 1032, so as to improve the space utilization of the recessed portion 1032 and reduce the occupation of the internal space of the host 10 shell. In addition, in this manner, since the first mounting portion 61a is arranged across the two connecting portions 61b, at least one of the two connecting portions 61b may be provided with a locking portion 63. For example, when both connecting portions 61b are provided with a locking portion 63, the locking effect of the scanning component 20 and the host 10 can be improved. In particular, when one of the locking portions 63 fails, the other locking portion 63 can still be locked, and the locking reliability of the scanning component 20 and the host 10 is higher.

[0226] Exemplarily, the first mounting portion 61a can be a strip-shaped structure, and the two connecting portions 61b can be connecting blocks. The third reset member 62 can also be a spring connected between the two connecting portions 61b. The first mounting portion 61a and the two connecting portions 61b are both provided with a wedge-shaped mating surface 6110, and the pressing member 64 can move along the Z direction.

[0227] When the host 10 and the scanning assembly 20 are folded, the two connecting parts 61b are in contact with the scanning assembly 20 under the elastic action of the third restoring member 62, and the locking part 63 extends into the second locking hole 20b on the scanning assembly 20 to lock the scanning assembly 20. When the scanning assembly 20 needs to be unfolded, the pressing member 64 can be pressed, and the pressing member 64 can drive the first mounting part 61a through the wedge-shaped matching surface 6110 to drive the two connecting parts 61b to approach each other, so that the locking part 63 can move in a direction away from the second locking hole 20b, thereby realizing the function of unlocking the scanning assembly 20.

[0228] Of course, based on the above-mentioned locking structure 60, the locking structure 60 may be set on the scanning component 20 instead of the recessed portion 1032, and then a corresponding card hole may be opened on the host 10 for cooperation, so that the function of locking and unlocking the scanning component 20 can also be realized.

[0229] The above embodiment has made a detailed introduction to the locking structure 60 between the host 10 and the scanning component 20. In actual products, in addition to using the above physical button operation mode to unlock the scanning pen 01, an electric lock structure can also be set to use an electromagnet or a motor to drive locking and unlocking. For example, the above locking structure 60 may not be provided with the button, but the movement of the locking frame 61 may be driven by a motor.

[0230] Please also read Figure 36 to Figure 38 , Figure 36 to Figure 38 2 and 3 show the structure of the scanning assembly 20 of this embodiment (the scanning unit and the battery are omitted in the figure). Specifically, the scanning assembly 20 includes the scanning housing 21 and the scanning module 23 (in the above Fig.11In addition to the scanning unit 24 shown above, the scanning unit 24 may also include a scanning unit 24. The scanning unit 24 includes a scanning bracket 24a and a pressure sensing element 24b. The scanning bracket 24a may be installed in the scanning housing 21, and the scanning bracket 24a has a scanning portion 240a. The scanning portion 240a extends out of the scanning housing 21 to contact the scanned object. The pressure sensing element 24b may be arranged on the scanning bracket 24a and located in the scanning housing 21. In other words, the present application adopts a pressure sensing detection method to determine whether the scanning pen 01 needs to scan. Specifically, it may be: the deformation of the scanning portion 240a of the scanning bracket 24a is sensed by the pressure sensing element 24b, so as to output the detection value to the circuit board of the scanning pen 01, and then the circuit board may control the scanning pen 01 to start the scanning function according to the detection value. Since the pressure sensing element 24b is arranged on the scanning bracket 24a, compared with the method of directly arranging the pressure sensing element 24b on the scanning housing 21, it can reduce the situation that the scanning pen 01 may be accidentally touched when the user holds the scanning housing 21.

[0231] Furthermore, the scanning housing 21 includes an inner wall 210 in the width direction Y, and the scanning bracket 24a is disposed close to the inner wall 210 of the scanning housing 21, and along the width direction Y, there is a gap between the portion of the scanning bracket 24a carrying the pressure sensing element 24b and the inner wall 210 of the scanning housing 21. Thus, the pressure sensing element 24b does not contact the inner wall 210 of the scanning housing 21, which can further reduce the situation where the user holds the scanning housing 21 and transmits pressure to the pressure sensing element 24b, causing the scanning pen 01 to erroneously activate the scanning function, and further improve the accuracy of preventing accidental touches of the scanning pen 01.

[0232] Combination Fig.39 As shown, optionally, the scanning unit 24 includes two, the inner side wall 210 of the scanning housing 21 includes a first inner wall surface 210a and a second inner wall surface 210b along the width direction Y, the two scanning units 24 are arranged at intervals in the width direction Y and are respectively arranged close to the first inner wall surface 210a and the second inner wall surface 210b, and the interval between the two scanning units 24 forms a scanning window 201 of the scanning component 20, and the scanning module 23 (see the aforementioned Fig.11 ) corresponds to the scanning window 201. In this way, during scanning, the two scanning parts 240a of the two scanning units 24 can contact the scanned object, and the contact with the scanned object is more balanced. At the same time, the scanning module 23 scans the scanned object through the scanning window 201 to achieve the scanning function. The two scanning units 24 are respectively close to the first inner wall surface 210a and the second inner wall surface 210b, so that a larger scanning window 201 can be set in the width direction Y, thereby increasing the scanning range of the scanning pen 01.

[0233] On the basis of the above, the scanning housing 21 of the present application may include a main housing 21a and a branch housing 21b, the main housing 21a is connected to one end of the host 10, and the above-mentioned scanning cavity 22 is formed in the main housing 21a. The scanning module 23 is arranged in the scanning cavity 22. The branch housing 21b is connected to one end of the main housing 21a away from the host 10 along the length direction X, and the branch housing 21b has the scanning window 201 corresponding to the scanning module 23, so that the scanning module 23 can scan the scanned object through the scanning window 201 on the branch housing 21b. The scanning bracket 24a can be installed at the connection between the main housing 21a and the branch housing 21b, and the scanning part 240a extends out of the branch housing 21b. The scanning shell 21 includes a main shell 21a and a branch shell 21b, and the scanning window 201 is formed by the branch shell 21b. At the same time, the scanning bracket 24a is installed at the connection between the main shell 21a and the branch shell 21b. In this way, when the scanning bracket 24a is damaged and needs to be replaced, it can be replaced by disassembling the branch shell 21b, without disassembling the entire main shell 21a, which is convenient for disassembly and replacement.

[0234] It can be understood that when the scanning bracket 24a is installed at the connection between the main shell 21a and the branch shell 21b, there is a gap between the outer surface of the scanning bracket 24a that carries the pressure sensing element 24b and the connection between the main shell 21a and the branch shell 21b, thereby keeping the pressure sensing element 24b from contacting the main shell 21a and the branch shell 21b, reducing the situation where the user holds the scanning shell 21 and transmits pressure to the pressure sensing element 24b, causing the scanning pen 01 to mistakenly activate the scanning function, and further improving the anti-mistouch accuracy of the scanning pen 01.

[0235] Furthermore, in order to facilitate the disassembly and assembly of the scanning module 23, battery, etc., which are arranged in the main housing 21a, the main housing 21a actually includes two sub-housing parts connected to each other along the thickness direction Z, that is, the branch housing 21b is actually connected to the front end of the main housing 21a (i.e., the end scanned by the user), and the branch housing 21b is mainly used to form the scanning window 201. At the same time, the two scanning units 24 can be installed by using the branch housing 21b, so that the two scanning units 24 do not interfere with each other. In this way, once one of the scanning units 24 is damaged or fails, the other scanning unit 24 can still work normally, effectively improving the reliability of the scanning pen 01.

[0236] Furthermore, a first mounting groove 211 is provided on the branch shell 21b, and the first mounting groove 211 is arranged toward the inner wall 210 of the main shell 21a. The scanning bracket 24a is installed in the first mounting groove 211, and along the width direction Y of the main shell 21a, there is a distance between the scanning bracket 24a and the inner wall 210 of the main shell 21a and the side wall surface of the first mounting groove 211. Therefore, the distance between the pressure sensing element 24b arranged on the scanning bracket 24a and the scanning shell 21 can be effectively maintained, preventing the user from transferring the force to the pressure sensing element 24b when holding the scanning shell 21, thereby causing the pressure sensing element 24b to output a signal to enable the scanning pen 01 to start the scanning function, that is, it can effectively prevent false triggering.

[0237] In some embodiments, the branch shell 21b is further provided with a through hole 212 that is open along the width direction Y of the main shell 21a. The through hole 212 is connected to the first mounting groove 211, and the scanning unit 240a extends out of the branch shell 21b through the through hole 212. In this way, the scanning unit 240a extends from the width direction Y of the branch shell 21b instead of from the length direction X of the branch shell 21b. This can further increase the distance from the scanning unit 240a to the scanning window 201, so that the branch shell 21b has more space in the length direction X and the width direction Y to set the scanning window 201, which is beneficial to increase the scanning range.

[0238] Optionally, the scanning portion 240a is generally a rod-shaped structure, or the scanning unit 24 may further include a roller portion 24c, which is movably disposed on the scanning portion 240a and is disposed corresponding to the perforation 212, and the roller portion 24c extends out of the perforation 212 to contact the scanned object. In other words, the roller portion 24c is used to contact the scanned object, so that rolling contact can be achieved, thereby reducing the friction when contacting the scanned object, and providing a better user experience.

[0239] Please also read Figures 37 to 41 In some embodiments, the scanning unit 24 further includes a second limiting bracket 24d, which is connected to the scanning bracket 24a and is located in the scanning housing 21. The second limiting bracket 24d is used to limit the scanning bracket 24a along the length direction X and / or the thickness direction Z of the scanning housing 21 (see the aforementioned Figure 4 , Figure 5). Along the direction from the bottom to the top of the scanning housing 21 (that is, in the thickness direction Z of the scanning housing 21), the second position-limiting bracket 24d is located between the scanning bracket 24a and the bottom of the scanning housing 21, and the second position-limiting bracket 24d and the scanning bracket 24a are connected to the scanning housing 21 by the same fastener (such as a screw). Specifically, a through hole is provided on the second position-limiting bracket 24d, and a corresponding through hole is also provided on the second mounting portion 241 of the scanning bracket 24a. The scanning housing 21 is provided with a connecting column with an opening, and the fasteners are sequentially passed through the above-mentioned through hole and the opening, so as to realize the connection of the second position-limiting bracket 24d and the scanning bracket 24a to the scanning housing 21. It can be understood that in other embodiments, the second limiting bracket 24d and the scanning bracket 24a may not be connected to the scanning shell 21 through the same fastener, but may be connected to the scanning shell 21 separately, or the second limiting bracket 24d and the scanning bracket 24a may also be connected to the scanning shell 21 by means of, for example, snap connection or riveting, which can be adjusted according to actual conditions and is not specifically limited in this embodiment.

[0240] Further, the scanning bracket 24a includes a second mounting portion 241 and a deformable portion 240 connected in sequence along the length direction X of the scanning housing 21, the second mounting portion 241 is mounted on the scanning housing 21, one end of the deformable portion 240 away from the second mounting portion 241 extends out of the scanning housing 21 to form a scanning portion 240a, and the pressure sensing element 24b is disposed on the deformable portion 240, and extends from the deformable portion 240 to at least partially located on the second mounting portion 241. The second limiting bracket 24d includes a connecting end 242 and a limiting end 243 opposite to each other, the connecting end 242 is connected to the second mounting portion 241, the limiting end 243 extends in a direction toward the scanning portion 240a, and a deformation gap 244 is formed between the limiting end 243 and the scanning portion 240a along the length direction X and / or the thickness direction Z of the scanning housing 21. That is to say, the part of the scanning bracket 24a that actually deforms is mainly at the deformation part 240, and when the second limiting bracket 24d is connected to the scanning bracket 24a, it is mainly connected to the second mounting part 241. In this way, the scanning bracket 24a can be fixed in the scanning housing 21 without affecting the deformation of the deformation part 240, so as to avoid the scanning bracket 24a from being separated from the scanning housing 21 when falling or impacting, which may affect the scanning function. At the same time, the limiting end 243 of the second limiting bracket 24d is along the length direction X and / or thickness direction Z of the scanning housing 21 (see the aforementioned Figure 4 , Figure 5) has a deformation gap 244 between the scanning portion 240a and the scanning portion 240a, so that when the scanning portion 240a contacts the scanned object and is deformed, the deformation gap 244 can provide a certain deformation space for the scanning portion 240a, so that the pressure sensing element 24b can sense the deformation. At the same time, the deformation gap 244 can limit the excessive deformation of the scanning portion 240a, thereby avoiding damage due to excessive deformation.

[0241] like Fig.40 and Fig.41 As shown, further, the deformation portion 240 includes a main body portion 240b and a scanning portion 240a, and a second mounting groove 2401 is provided on a side surface of the main body portion 240b facing the bottom of the scanning shell 21, and the second mounting groove 2401 extends to the second mounting portion 241, and the pressure sensing element 24b is arranged in the second mounting groove 2401. Along the length direction X of the scanning shell 21, a step portion 2402 is formed between the second mounting groove 2401 and the scanning portion 240a, and the limiting end 243 is provided with a second limiting portion 243a, and the second limiting portion 243a is arranged corresponding to the step portion 2402, and a deformation gap 244 is formed between the two. Specifically, the step portion 2402 is mainly formed by the inner wall surface 2401a of the second mounting groove 2401 along the length direction X of the scanning shell 21 and a side surface 2401b (hereinafter referred to as the side surface) connected to the scanning portion 240a and the inner wall surface of the second mounting groove 2401, so that, along the length direction X, a first deformation gap 244a is formed between the second limiting portion 243a and the inner wall surface 2401a of the second mounting groove 2401, and along the thickness direction Z, a second deformation gap 244b is formed between the second limiting portion 243a and the side surface 2401b of the scanning portion 240a, that is, the above-mentioned deformation gap 244 actually includes the first deformation gap 244a and the second deformation gap 244b, so that the limiting end 243 can provide deformation space for the deformation of the scanning portion 240a in both the length direction X and the thickness direction Z, and can also limit the damage caused by excessive deformation. Of course, it is understandable that in other embodiments, the scanning portion 240a can be restricted in only one direction, for example, the deformation gap 244 is provided between the second limiting portion 243a and the inner wall surface of the second mounting groove 2401 only in the length direction X, or the deformation gap 244 is provided between the second limiting portion 243a and one side surface of the scanning portion 240a only in the thickness direction Z.

[0242] In some embodiments, along the thickness direction Z of the scanning housing 21, the opening of the second mounting groove 2401 faces the bottom surface of the scanning housing 21, and the bottom of the second mounting groove 2401 is an inclined surface, which extends obliquely from the connection with the scanning portion 240a toward the direction of the second mounting portion 241, so that the thickness of the main body 240b is gradually reduced. The pressure sensing element 24b is arranged on the inclined surface, and a stress groove 2403 is arranged on the inclined surface. The stress groove 2403 is arranged close to the scanning portion 240a, and the sensing part of the pressure sensing element 24b is arranged corresponding to the stress groove 2403. By setting the bottom of the second mounting groove 2401 as an inclined surface, the thickness of the main body 240b is gradually reduced, so that the deformation of the main body 240b can be made easier, and the pressure sensing element 24b can more easily sense the deformation. In addition, a stress groove 2403 is provided on the inclined surface, and the stress groove 2403 is provided close to the scanning portion 240a, and the sensing portion of the pressure sensing element 24b is provided corresponding to the stress groove 2403, so that the stress groove 2403 can be the concentrated point of deformation, and the pressure sensing element 24b can more easily sense the deformation, making its identification more accurate.

[0243] The scanning pen disclosed in the present application sets the host to have a width b1 that satisfies 40mm≤b1≤70mm, which is much larger than the pen body width of conventional scanning pens on the market. Therefore, the display screen set on the host can be selected to be larger in size, thereby increasing the display area of ​​the host and facilitating user viewing. On this basis, the present application further considers the ratio of the width of the scanning shell of the scanning component to the width of the host, that is, under the premise that the width of the host is increased, the width of the scanning shell is smaller than the width of the host. At the same time, it is further limited that the scanning shell of the scanning component has a certain length in the length direction of the host, so that the scanning shell can be held by the user. Therefore, child users can choose to hold on the scanning shell whose width is smaller than that of the host, while adult users can choose to hold on the host or on the scanning shell according to actual conditions. Therefore, the present application can, on the basis of taking into account the expansion of the width size of the host and the display screen, further solve the problem of reduced user adaptability of holding with one hand (for example, child users cannot hold or cannot hold for a long time) caused by the expansion of the width size of the host and the display screen.

[0244] On the basis that the width of the above-mentioned host is increased and the scanning shell has a certain length for holding, considering that if it is held on the scanning shell, that is, compared with holding it on the host, holding it on the scanning shell is equivalent to holding it at the front end of the scanning pen, if the scanning component is too light, when the user holds it, due to the weight of the scanning pen itself, the scanning pen as a whole will tip over to the end of the host away from the scanning component. Based on this, the present application also takes the weight of the scanning component and the host into consideration, by limiting the ratio of the overall weight of the scanning component to the weight of the host to be greater than or equal to a preset threshold, or making the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell less than or equal to 2 / 3 of the length of the host, that is, avoiding the center of gravity of the scanning pen being located at the end of the host (that is, away from the end of the scanning component), so that the center of gravity of the scanning pen is shifted as much as possible to the end where the host is connected to the scanning component, thereby avoiding the problem of top-heavy tipping when the user holds it on the scanning shell.

[0245] Embodiment 2

[0246] Please refer again Figure 2 The present application also discloses a scanning pen 01, including a host 10 and a scanning component 20, the host 10 is provided with a display screen 30, and the width b1 of the host 10 satisfies 20mm≤b1≤100mm; the scanning component includes a scanning shell 21 and a scanning module 23 arranged in the scanning shell 21, the scanning module 23 is used to scan the scanned object and display the scanning result on the display screen, and the scanning shell 21 is connected to one end of the host 10 along the length direction; the width b2 of the scanning shell 21 is less than the width b1 of the host 10, and the width b2 of the scanning shell 21 satisfies 19mm≤b2≤80mm, and the scanning shell 21 has a certain length in the length direction of the host 10 so that the scanning shell 21 can be grasped.

[0247] Considering that the host 10 has a relatively large width, while the width of the scanning housing 21 is smaller than that of the host 10, and at the same time, the scanning housing 21 has a certain length, in this way, users with small hands can choose to hold the scanning housing 21. Since the scanning housing 21 is at one end of the length direction X of the host 10, because the overall size of the host 10 is relatively large, and the host 10 carries devices such as the display screen 30, the host 10 is relatively heavy, and the center of gravity of the scanning pen 01 may be offset to the end of the host 10 away from the scanning component 20. This results in a greater torque in the direction of the center of gravity of the scanning pen when the user holds the scanning housing 21, especially when a child user holds it, the hand needs to apply a greater force to clamp the scanning pen, otherwise the top may be heavy, that is, the host 10 may overturn. Based on this, the present application also considers the distribution of the center of gravity of the scanning pen 01. Specifically, the present application limits the overall weight of the scanning component 20 to be less than or equal to the overall weight of the host, so that the center of gravity of the scanning pen 01 can be adjusted toward one end of the host 10 close to the scanning component 20, thereby alleviating the problem that when the user holds the scanning shell 21, the overall weight of the scanning shell 21 is too light, while the overall weight of the host 10 is too heavy, resulting in top-heavy condition, that is, alleviating the possibility that the host 10 may overturn when held.

[0248] In some embodiments, the present embodiment also considers that the ratio of the overall weight of the scanning component 20 to the overall weight of the host 10 is greater than or equal to a preset threshold. Specifically, the preset threshold may be M, and M satisfies: 0.1≤M≤1. Exemplarily, M may be 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.8 and 0.9, etc. Thus, the overall weight of the scanning component 20 can be slightly closer to the overall weight of the host 10, so as to avoid the problem that the scanning pen 01 is tilted toward the end of the host 10 away from the scanning component 20 when the scanning pen 01 is held on the scanning housing 21 due to the large weight difference between the two, thereby requiring the user to exert greater force to hold the scanning housing 21 tightly, affecting the user's holding experience.

[0249] Furthermore, the preset threshold value M may further satisfy: 0.25≤M≤1. That is to say, the overall weight of the scanning component 20 is closer to the overall weight of the host 10, so that the center of gravity of the scanning pen 01 can be more offset toward the end of the host 10 close to the scanning component 20, and even the center of gravity of the scanning pen 01 may fall on the scanning component 20. In this way, when the user holds the scanning housing 21, the gravity of the host 10 has a reduced effect on the center of gravity of the scanning pen 01. When the user holds the scanning pen 01, the center of gravity will be offset toward the scanning component 20 due to the gravity of the scanning component 20. When the user holds the scanning housing 21, the scanning pen 01 will actively lean forward toward the end of the scanning housing 21 away from the host 10 due to the gravity, so that the user does not need to use too much force to clamp the scanning pen 01, and the scanning pen 01 will not fall toward the host 10, thereby reducing the clamping force applied by the user when holding the scanning pen 01 and improving the user's holding experience.

[0250] In other embodiments, considering the overturning problem when holding the scanning housing 21, the scanning housing 21 can be counterbalanced based on the position of the center of gravity. Specifically, in the length direction X of the host 10, the distance L2 from the center of gravity O of the scanning pen 01 to the end face of the host 10 connected to the scanning housing 21 is less than or equal to 2 / 3 of the length L of the host 10. For example, the distance L2 from the center of gravity O of the scanning pen 01 to the end face of the host 10 connected to the scanning housing 21 can be 1 / 3L, 1 / 2L or 2 / 3L, etc. In other words, the center of gravity O of the scanning pen 01 is close to the end of the host 10 connected to the scanning housing 21. In this way, when counterbalance is performed on the scanning housing 21, as long as the center of gravity O of the scanning pen 01 can be in the above position, the overturning problem when holding the scanning housing 21 can be alleviated.

[0251] It is understandable that the above Figure 2 In the figure, the center of gravity of the scanning pen 01 is simply shown for the sake of convenience, and the center of gravity is not limited to Figure 2 In addition, the position of the center of gravity of the scanning pen 01 can be determined according to the suspension method or support method in the relevant technology, which will not be described in detail in this embodiment.

[0252] The scanning pen disclosed in the present application sets the host to have a width b1 that satisfies 20mm≤b1≤100mm. In fact, b1 can further satisfy 40mm≤b1≤70mm, which is much larger than the pen body width of conventional scanning pens on the market. Therefore, the display screen set on the host can be selected to be larger in size, thereby increasing the display area of ​​the host, which is beneficial for users to watch. On this basis, the present application further considers that the width b2 of the scanning shell of the scanning component satisfies 19mm≤b2≤80mm. In fact, b2 can further satisfy 25mm≤b2≤35mm. At the same time, the width of the scanning shell 21 is smaller than the width of the host 10, that is, under the premise that the width of the host 10 is increased, the width of the scanning shell 21 is smaller than the width of the host 10. At the same time, it is further limited that the scanning shell 21 of the scanning component 20 has a certain length in the length direction of the host 10, so that the scanning shell 21 can be held by the user. Therefore, a child user can choose to hold the scanning shell whose width is smaller than that of the host, while an adult user can choose to hold the host or the scanning shell according to actual conditions. Therefore, the present application can, on the basis of taking into account the expansion of the width size of the host 10 and the display screen, further solve the problem of reduced user adaptability of holding with one hand due to the expansion of the width size of the host and the display screen (for example, children users cannot hold it or cannot hold it for a long time).

[0253] On the basis that the width of the above-mentioned host is increased and the scanning shell has a certain length for holding, considering that if it is held on the scanning shell, that is, compared with holding it on the host, holding it on the scanning shell is equivalent to holding it at the front end of the scanning pen, if the scanning component is too light, when the user holds it, due to the weight of the scanning pen itself, the scanning pen as a whole will tip over to the end of the host away from the scanning component. Based on this, the present application also takes the weight of the scanning component and the host into consideration, by limiting the ratio of the overall weight of the scanning component to the weight of the host to be greater than or equal to a preset threshold, or making the distance from the center of gravity of the scanning pen to the end face of the host connected to the scanning shell less than or equal to 2 / 3 of the length of the host, that is, avoiding the center of gravity of the scanning pen being located at the end of the host (that is, away from the end of the scanning component), so that the center of gravity of the scanning pen is shifted as much as possible to the end where the host is connected to the scanning component, thereby avoiding the problem of top-heavy tipping when the user holds it on the scanning shell.

[0254] It is worth noting that the scanning pen disclosed in the second embodiment of the present application also includes other parts, such as the size of the main unit 10, the size of the scanning component, and the specific structure of the main unit and the scanning component, the locking structure, etc., which are the same as the specific structure of the scanning pen disclosed in the first embodiment and will not be repeated here.

[0255] The scanning pen disclosed in the embodiment of the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the core idea of ​​the scanning pen of the present application; at the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
