[0002] The pen tip structures of the current scanning pens on the market are basically the same, and the scanning camera of the scanning pen is located at the back of the pen tip. Due to the large size of the scanning pen body, the scanning pen is easy to block the person's line of sight during the scanning process, causing the scanning area to become a blind spot, and the user cannot see the scanned content, which will affect the consumer experience to a certain extent. In addition, since the scanned content cannot be seen, the scanning area may deviate, resulting in scanning errors. Summary of the invention

[0013] Optionally, taking the surface shell as a vertical reference plane, a central axis of a lens of the camera assembly is arranged obliquely downward relative to the surface shell.

[0014] Optionally, the auxiliary mirror group includes a second light-transmitting mirror and a reflective mirror, the second light-transmitting mirror is installed parallel to the surface shell, the reflective mirror is installed at the top end of the second light-transmitting mirror and extends in the direction away from the surface shell, the lens of the camera assembly is arranged opposite to the reflective mirror, and the scanning angle of the camera assembly is transmitted through the second light-transmitting mirror and emitted by the reflective mirror to form a third scanning area located in front of the bottom end of the surface shell.

DETAILED DESCRIPTION

[0027] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] When using existing scanning pen products on the market, the scanning area is located at the back of the bottom of the pen tip. The pen body will block the line of sight, and the scanning area is a blind spot. Some products will add a transparent lens at the pen tip, through which the user can see part of the scanning area. However, due to size limitations, only a relatively small part of the scanning area can be seen through the lens. In addition, if Figure 1 As shown, during use, as the inclination angle α increases, the scanning area seen through the lens becomes smaller, or even completely invisible. The scanning area is in the blind area of ​​the visual field, which affects the consumer's experience. In addition, since the content to be scanned cannot be seen, blind scanning may result in skew scanning, resulting in scanning errors. Therefore, a scanning pen described in the following embodiment is proposed.

[0031] Embodiment 1: A scanning pen based on prism refraction.

[0032] like Figure 2 , Figure 3 As shown, this embodiment provides a scanning pen, including: a shell 1 and a camera assembly 2, the shell 1 has a bottom shell 101 close to the operator and a surface shell 102 away from the operator; the camera assembly 2 is installed in the shell 1; the surface shell 102 is provided with a scanning window, and the lens of the camera assembly 2 is configured to scan and photograph the front area of ​​the surface shell 102 through the scanning window.

[0033] Based on this solution, when the scanning pen is used for scanning, the bottom shell 101 is against the scanning plane, and the shell 1 as a whole is inclined toward the bottom shell 101. A scanning window is provided on the surface shell 102, and a camera assembly 2 is installed inside the shell 1. The lens of the camera assembly 2 is opposite to the scanning window, so that the camera assembly 2 can scan the area in front of the surface shell 102 through the scanning window. Compared with the traditional scanning pen scanning method, this solution moves the scanning area forward, from the rear of the bottom shell 101 to the front of the surface shell 102, so that the operator will not encounter the situation where the scanning area is blocked and cannot be seen clearly when using it. It can be understood that the bottom end of the surface shell 102 is the starting point for scanning. The operator can clearly see the scanning starting point and the scanning content, so as to accurately scan the content to be scanned, and during the scanning process, the scanning position and posture can be adjusted at any time according to the scanning situation, so as to improve the scanning accuracy and reduce the occurrence of scanning errors. Moreover, this scanning method is more novel, and the operator will have a better experience when using it.

[0034] Preferably, an auxiliary lens group 3 is further included, which is mounted on the face shell 102, the lens of the camera assembly 2 corresponds to the auxiliary lens group 3, and the framing optical path of the camera assembly 2 passes through the auxiliary lens group 3. The framing optical path of the camera assembly 2 is adjusted by the auxiliary lens group 3, so that the framing optical path of the camera assembly 2 can accurately fall in front of the face shell 102.

[0035] Specifically, the auxiliary lens group 3 is a prism 301, and the prism 301 is installed at the scanning window of the face shell 102, and the lens of the camera assembly 2 faces the prism 301, so that the scanning angle of the camera assembly 2 is refracted by the prism 301 to form a first scanning area 4 located in front of the bottom end of the face shell 102. The first scanning area 4 is formed by refracting the framing light path of the camera assembly 2 through the prism 301. The first scanning area 4 is close to the bottom end of the face shell 102. Since the first scanning area 4 is invisible, the bottom end of the face shell 102 can be used as a reference point for the scanning starting point. The operator can determine the scanning starting point through the position of the bottom end of the face shell 102, and then determine whether the scanning position is accurate.

[0036] In some embodiments, since the prism 301 has a refractive effect, in order to ensure that the framing light path of the camera assembly 2 can accurately form the first scanning area 4 located in front of the bottom end of the face shell 102 after being refracted by the prism 301, the prism 301 and the face shell 102 cannot be arranged in parallel, and there needs to be an angle. The size of this angle can be adjusted according to the refractive index of the prism 301, and it is only necessary to ensure that the first scanning area 4 formed after refraction is located in front of the bottom end of the face shell 102.

[0037] It is worth mentioning that the prism 301 is movably installed on the scanning window. The movability mentioned here means that the angle is adjustable. In this way, when different prisms 301 are selected and installed on the scanning window, the angle between them and the surface shell 102 can be adjusted to realize the position of the first scanning area 4 formed by refraction, so that the first scanning area 4 can be accurately moved to the front of the bottom end of the surface shell 102.

[0038] Optionally, the first scanning area 4 formed by the camera assembly 2 after refraction by the prism 301 is a square frame, and there is a gap m between the edge of the first scanning area 4 close to the shell 1 and the front line formed by the projection of the face shell 102 along its surface, and the value range of the gap m is between 0.5mm and 1mm. It can be understood that the framing light path of the camera assembly 2 is parallel to the scanning plane after refraction by the prism 301, so setting the gap m can prevent the face shell 102 from blocking the refraction of the framing light path of the camera assembly 2, that is, the camera assembly 2 will not scan the face shell 102. In addition, the specific value range of the gap can be adaptively adjusted according to actual conditions. When the gap m=0.5mm, the first scanning area 4 and the face shell 102 are closest, and the reference accuracy of the scanning starting point is the highest.

[0039] It should be noted that, with the face shell 102 as a vertical reference plane, the central axis of the lens of the camera assembly 2 is arranged obliquely downward relative to the face shell 102 and forms an angle a with the face shell 102 .

[0040] Embodiment 2: A scanning pen based on transmission by a first light-transmitting mirror.

[0041] like Figure 4 , Figure 5 As shown, this embodiment discloses a scanning pen that forms a second scanning area 5 based on the first light-transmitting mirror 302. In this scheme, the auxiliary mirror group 3 is the first light-transmitting mirror 302, and the first light-transmitting mirror 302 is embedded in the scanning window. The lens of the camera component 2 is opposite to the first light-transmitting mirror 302. The scanning angle of the camera component 2 is transmitted through the first light-transmitting mirror 302 to form a second scanning area 5 located in front of the bottom end of the face shell 102.

[0042] Based on the above scheme, the difference from the first embodiment is that the prism 301 is replaced by the first light-transmitting mirror 302, and the framing light path of the camera component 2 will not be refracted after passing through the first light-transmitting mirror 302, but will directly pass through the first light-transmitting mirror 302 to form a second scanning area 5 on the scanning plane. In order to ensure that the second scanning area 5 can be accurately formed, the first light-transmitting mirror 302 needs to be arranged in parallel with the surface shell 102, specifically, the first light-transmitting mirror 302 and the surface shell 102 are in the same plane, and the lens of the camera component 2 needs to be completely opposite to the first light-transmitting mirror 302. The completely opposite mentioned here means facing, but not vertically facing, but facing diagonally downward. It can be understood that the lens of the camera component 2 is not blocked by the surface shell 102, and is facing the first light-transmitting mirror 302 for scanning and shooting.

[0043] It should be noted that, in this embodiment, the surface shell 102 is used as a vertical reference plane, the central axis of the lens of the camera assembly 2 is arranged obliquely downward relative to the surface shell 102, and an angle b is formed between the central axis of the lens of the camera assembly 2 and the surface shell 102. Since the scanning angle of the camera assembly 2 in Embodiment 1 is the first scanning area 4 formed after refraction, and the scanning angle of the camera assembly 2 in this embodiment is the second scanning area 5 formed directly through the first light-transmitting mirror 302, the angle b is smaller than the angle a.

[0044] Embodiment 3: A scanning pen based on reflector reflection.

[0045] like Figure 6 , Figure 7As shown, this embodiment discloses a scanning pen that forms a third scanning area 6 based on reflection by a reflector 304, the auxiliary mirror group 3 includes a second light-transmitting mirror 303 and a reflector 304, the second light-transmitting mirror 303 is installed in parallel with the surface shell 102, the reflector 304 is installed on the top of the second light-transmitting mirror 303 and extends in a direction away from the surface shell 102, the lens of the camera component 2 is arranged opposite to the reflector 304, and the scanning angle of the camera component 2 is transmitted by the second light-transmitting mirror 303 and emitted by the reflector 304 to form a third scanning area 6 located in front of the bottom end of the surface shell 102.

[0046] The difference between this embodiment and the first and second embodiments is that the auxiliary lens group 3 includes a second light-transmitting mirror 303 and a reflective mirror 304, and the orientation of the lens of the camera assembly 2 is also different. In this solution, the surface shell 102 is used as a vertical reference plane, and the central axis of the lens of the camera assembly 2 is arranged obliquely upward relative to the surface shell 102, that is, the lens of the camera assembly 2 is arranged upward, and the framing light path of the camera assembly 2 is sequentially transmitted through the second light-transmitting mirror 303 to the reflective mirror 304, and then reflected by the reflective mirror 304 to the scanning plane to form the third scanning area 6.

[0047] It should be noted that the auxiliary mirror group 3 in the three embodiments is configured to make the scanning area of ​​the scanning pen visible during the scanning process, to provide a good scanning experience, to improve the accuracy of the pen placement position, to reduce the skewness of the scanning track, and to achieve higher scanning accuracy.

[0048] Optionally, the surface shell 102 is provided with a mounting portion 1021, and the reflector 304 is fitted and installed at the bottom of the mounting portion 1021. The mounting portion 1021 extends away from the bottom shell 101, and the extension distance is consistent with the size of the framing light path of the camera assembly 2. In this way, the reflector 304 arranged on the mounting portion 1021 can effectively reflect its framing light path in its entirety and form an effective third scanning area 6.

[0049] Preferably, a camera slot for installing the camera assembly 2 is provided inside the housing 1 , and the position and orientation of the camera slot need to be adjusted according to the orientation of the lens of the camera assembly 2 to adapt to the scanning areas of the three embodiments.

[0050] In some embodiments, the surface shell 102 and the bottom shell 101 are detachably connected, so as to facilitate the assembly and disassembly of the surface shell 102 and the adjustment of the internal camera assembly 2.

[0051] Optionally, a display screen is further provided on the surface shell 102 , and a speaker is provided on the bottom shell 101 .

[0052] It is worth mentioning that, in order to improve versatility and facilitate adjustment of the lens orientation of the camera assembly 2, an adjustment assembly is provided on the camera slot, and the adjustment assembly is connected to the camera assembly 2. The lens of the camera assembly 2 can be rotated in the camera slot through the adjustment assembly to adjust its angle to meet the scanning orientation under different scanning conditions. This design does not require the design of camera slots of different shapes for different auxiliary lens groups 3. It only needs to adjust the position of the camera assembly 2 through the adjustment assembly and then replace the corresponding face shell 102.

[0053] To summarize, the scanning pen described in the present application changes the framing light path of the camera component 2 through the prism 301 or the reflector 304, and then adjusts the position of the scanning area so that the scanning area always falls within the operator's line of sight. The scanning area is clearly visible before and during scanning, which can enhance the operator's control over the scanning pen and reduce the possibility of scanning errors.
