Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a dictionary pen. Background Art

[0002] Currently, dictionary pens, as a relatively new consumer electronic product, are increasingly used in auxiliary learning applications, but their overall structure is relatively limited and lacks a sense of intelligence.

[0003] Traditional dictionary pens usually use compressible movable feet to trigger the scanning function, that is, compressible and resilient springs and spring pins are used as the extension and extension assist of the movable feet and the mechanism for triggering the scan. However, since the springs and spring pins are movable parts, they are prone to wear or loosening during use, resulting in gaps in the movable foot area, which in turn causes shaking and false touches. In addition, this design fails to fundamentally solve the problem of the limited overall shape of the dictionary pen. Another solution is to fix the movable foot and use pressure sensing or button methods to trigger the scanning function. In this design, the movable foot only serves as a supporting structure during scanning and no longer participates in the scanning triggering process. Although this method reduces the possibility of false touches to a certain extent, since the movable foot still needs to occupy a certain space, the overall aesthetics and intelligence of the dictionary pen are still limited.

[0004] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content

[0005] The utility model provides a method for solving the problem that the movable foot arrangement mode of the existing dictionary pen not only affects the aesthetics and intelligence of the product, but also easily leads to the problem of accidental touch during use.

[0006] The utility model provides a dictionary pen, comprising:

[0007] case;

[0008] A movable foot is retractably arranged on the shell;

[0009] A linear drive mechanism is installed in the housing and is in transmission connection with the movable foot;

[0010] When the dictionary pen is in a scanning state, the movable foot extends out of the shell to frame the content to be scanned; when the dictionary pen is in a non-scanning state, the movable foot is accommodated in the shell.

[0011] According to the dictionary pen provided by the present invention, the linear drive mechanism includes a rotary drive member, a screw and a threaded sleeve, the movable foot is provided with a connecting lug, one end of the screw is fixedly connected to the connecting lug, the screw is passed through the threaded sleeve and is threadedly connected to the threaded sleeve, and the rotary drive member is used to drive the threaded sleeve to rotate.

[0012] According to the dictionary pen provided by the present invention, a limiting plate is provided on the inner wall of the shell, and when the movable foot extends out of the shell, the connecting lug abuts against the limiting plate.

[0013] According to the dictionary pen provided by the present invention, the shell has a guide plate, the guide plate connects the limit plate and the scanning end of the shell, and the inner wall of the movable foot is in contact with the guide plate.

[0014] According to the dictionary pen provided by the present invention, the shell has a retaining wall, and when the movable foot is retracted into the shell, the inner end of the movable foot abuts against the retaining wall.

[0015] The dictionary pen provided by the utility model further includes a camera module, which is fixed in the shell. The movable foot is a U-shaped plate, and the U-shaped plate is provided with an avoidance through hole for avoiding the camera module.

[0016] According to the dictionary pen provided by the present invention, the movable foot includes two plate-shaped supporting feet, the two supporting feet are symmetrically arranged along the vertical central axis of the shell, and each of the supporting feet is transmission-connected to one of the linear drive mechanisms.

[0017] According to the dictionary pen provided by the present invention, when the movable foot is retracted into the shell, the end of the movable foot is flush with the scanning end of the shell.

[0018] According to the dictionary pen provided by the present invention, it also includes a main board and a button connected to the main board. The button can be pressed and installed on the shell. The linear drive mechanism is electrically connected to the main board. The main board is used to control the linear drive mechanism based on the pressing signal of the button to drive the movable foot to extend and retract relative to the shell.

[0019] According to the dictionary pen provided by the present invention, the button is a mechanical button, which is arranged beside the shell.

[0020] The above technical solution of the utility model has the following beneficial effects:

[0021] The dictionary pen of the present invention has a movable foot that is retractably arranged in a shell and is connected to a linear drive mechanism in the shell. The linear drive mechanism can drive the movable foot to extend out of the shell or retract into the shell. When the dictionary pen is in a scanning state, the movable foot extends out of the shell to frame the content to be scanned; when the dictionary pen is in a non-scanning state, the movable foot is accommodated in the shell. Since the extension and retraction of the movable foot is driven by the linear drive mechanism, the movement is smoother and faster, avoiding the shaking and accidental touch problems caused by the design of traditional movable feet, and improving the stability of the product.

[0028] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 3 The utility model provides a dictionary pen, including a shell 1, a movable foot 2 and at least one linear drive mechanism. The shell 1 includes a rear shell and a front shell that are relatively arranged. The rear shell and the front shell together form a cavity for accommodating internal components. It should be noted that, in order to facilitate the illustration of the internal components of the dictionary pen, only the rear shell is illustrated in the figure. The scanning end of the shell 1 is provided with a window connected to the cavity, and the movable foot 2 is retractably arranged in the shell 1 corresponding to the position of the window. The movable foot 2 is used to provide scanning support when it is extended from the shell 1. The linear drive mechanism is installed in the shell 1 and is connected to the movable foot 2. The linear drive mechanism is used to drive the telescopic movement of the movable foot 2. When the dictionary pen is in a scanning state, the movable foot 2 is extended out of the shell 1 to frame the content to be scanned. When the dictionary pen is in a non-scanning state, the movable foot 2 is accommodated in the shell 1.

[0030] In one embodiment, the movable leg 2 comprises two separate legs, each of which is connected to a linear drive mechanism, or the same linear drive mechanism drives the two legs to move synchronously. In another embodiment, the movable leg 2 is an integrated structure having two legs, and the linear drive mechanism drives the movable leg 2 to extend and retract.

[0031] Because the extension and retraction of the movable foot 2 in this utility model is driven by a linear drive mechanism, the movement is smoother and faster, avoiding the shaking and accidental touch problems caused by traditional movable foot designs, and improving the stability of the product. Furthermore, because the movable foot 2 is housed within the housing 1 when not scanning, there is no need to reserve space for the movable foot in the external structure of the dictionary pen, which enhances the overall aesthetics and intelligence of the product, facilitates storage, and prevents accidental touches when not in use.

[0032] Specifically, see Figure 1 The inner wall of the movable foot 2 is provided with a connecting lug 201, and the linear drive mechanism is connected to the movable foot 2 via the connecting lug 201. The linear drive mechanism includes a rotary drive member 4, a screw 7, and a threaded sleeve 3. One end of the screw 7 is fixedly connected to the connecting lug 201. The screw 7 passes through the threaded sleeve 3 and is threadedly connected to the threaded sleeve 3. One end of the threaded sleeve 3 is fixedly connected to the output shaft of the rotary drive member 4. The rotary drive member 4 is used to drive the threaded sleeve 3 to rotate. The rotation of the threaded sleeve 3 drives the screw 7 to move linearly up and down along the vertical center axis of the housing 1, thereby achieving linear telescopic motion of the movable foot 2.

[0033] The rotary drive component 4 may be a servo motor, a stepping motor, or the like.

[0034] In other embodiments, the linear drive mechanism may also be other types of drive mechanisms. For example, the linear drive mechanism includes an electric push rod that can directly drive the movable leg 2 to perform telescopic movement. In another example, the linear drive mechanism includes a screw module, and the slider of the screw module is connected to the movable leg 2 to drive the movable leg 2 to perform telescopic movement.

[0035] Among them, the length of the threaded sleeve 3 is greater than the moving distance of the movable foot 2 along the telescopic direction, ensuring that the screw 7 is always in a threaded connection state with the threaded sleeve 3, so that the movable foot 2 can move to a preset position, avoiding the moving range of the movable foot 2 being too limited due to the length of the threaded sleeve 3.

[0036] See Figure 1 and Figure 3 The inner wall of the housing 1 is provided with a limit plate 8, which is located on the side of the connecting lug 201 close to the scanning end. The limit plate 8 is used to limit the position of the movable foot 2 extending out of the housing 1. When the movable foot 2 is accommodated in the housing 1, there is a certain gap between the connecting lug 201 on the movable foot 2 and the limit plate 8. When the movable foot 2 extends out of the housing 1 to a predetermined distance, the connecting lug 201 on the movable foot 2 abuts against the limit plate 8, thereby playing a positioning role and achieving the purpose of limiting the extension distance of the movable foot 2.

[0037] In one embodiment, in order to prevent the limiting plate 8 from affecting the telescopic movement of the movable foot 2, a certain distance is provided between the limiting plate 8 and the inner wall of the movable foot 2, thereby preventing the movable foot 2 from rubbing against the limiting plate 8 during the telescopic movement.

[0038] like Figure 1 As shown, the movable foot 2 has two connecting lugs 201. Correspondingly, two limiting plates 8 are provided, one on each side of the scanning window. When the movable foot 2 extends out of the housing 1 to a predetermined distance, the connecting lugs 201 on the movable foot 2 abut against the corresponding limiting plates 8. Alternatively, only one connecting lug 201 and one limiting plate 8 may be provided.

[0039] In other embodiments of the present invention, the limit plate 8 may not be provided on the inner wall of the housing 1, but the extension and retraction distance of the movable leg 2 may be directly controlled by the rotary drive member 4. Specifically, the extension and retraction distance of the movable leg 2 may be controlled by controlling the rotation time of the rotary drive member 4.

[0040] In one embodiment, a guide plate 9 is further provided on the inner wall of the housing 1. The guide plate 9 connects the limit plate 8 to the scanning end of the housing 1. The inner wall of the movable foot 2 is in contact with the guide plate 9, and the guide plate 9 is used to guide the movement of the movable foot 2. The guide plate 9 extends along the length of the scanning window, sealing the scanning end of the housing 1 on the one hand and guiding the extension and retraction of the movable foot 2 on the other hand.

[0041] One end of the guide plate 9 is flush with the limit plate 8, and the other end of the guide plate 9 is flush with the scanning end of the housing 1. This ensures that the guide plate 9 can function as a guide while preventing the limit plate 8 from being exposed. Alternatively, one end of the guide plate 9 can be flush with the scanning end of the housing 1, while the other end extends into the interior of the housing 1 through the limit plate 8, as long as it can provide guidance for the extension and retraction of the movable foot 2.

[0042] For example, a sliding groove is provided on the side of the guide plate 9 facing the movable foot 2, and the movable foot 2 can be slidably embedded in the sliding groove. The sliding groove can provide constraints on the movement of the movable foot 2 in the thickness direction of the dictionary pen, ensuring that the movable foot 2 does not deviate in the thickness direction of the dictionary pen.

[0043] In one embodiment, a retaining wall 10 is further provided on the inner wall of the housing 1. The retaining wall 10 is located on the side of the movable foot 2 away from the scanning end. The retaining wall 10 is used to limit the retraction of the movable foot 2 into the housing 1. When the movable foot 2 is retracted into the housing 1, the inner end of the movable foot 2 abuts against the retaining wall 10, thereby achieving the purpose of limiting the retraction position of the movable foot 2.

[0044] It should be noted that the inner end of the movable leg 2 refers to the end of the movable leg 2 located inside the housing 1. In the case where the movable leg 2 includes two separately provided legs, the inner end of the movable leg 2 refers to the end of each leg located inside the housing 1. In the case where the movable leg 2 is a one-piece structure with two legs, the inner end of the movable leg 2 refers to at least a portion of the movable leg 2 connecting the two legs.

[0045] When the inner end of the movable foot 2 abuts the retaining wall 10, the outer end of the movable foot 2 is flush with the scanning end of the housing 1. It should be noted that the outer end of the movable foot 2 being flush with the scanning end of the housing 1 means that the outer end of the movable foot 2 smoothly transitions to the scanning end of the housing 1, and the outer end of the movable foot 2 does not protrude beyond the housing 1. Of course, when the inner end of the movable foot 2 abuts the retaining wall 10, the outer end of the movable foot 2 may also be slightly lower than the scanning end of the housing 1.

[0046] In one embodiment, the movable foot 2 is a U-shaped plate. The dictionary pen further includes a camera module, which is fixed in the housing 1 and arranged opposite the scanning end. The camera module is used to scan the content selected by the movable foot 2. Figure 2 As shown, the U-shaped plate is provided with an avoidance through hole 203 for avoiding the camera module, thereby ensuring that the camera module can scan the content framed by the movable foot 2.

[0047] The size of the avoidance through hole 203 is not limited here, and is subject to not interfering with the shooting of the camera module.

[0048] See Figure 3In this embodiment, the movable foot 2 includes two plate-shaped legs 202, symmetrically arranged along the vertical center axis of the housing 1. Each leg 202 is in transmission connection with a linear drive mechanism. The vertical center axis of the housing 1 refers to the center axis of the housing 1 extending along the length of the dictionary pen. By having two linear drive mechanisms drive the two legs 202, respectively, the linear drive mechanisms can avoid the electronic components located in the middle of the housing 1, ensuring the stability and reliability of the telescopic movement of the movable foot 2.

[0049] The movable foot 2 provided in this embodiment is a U-shaped plate, which is composed of two integrally connected legs 202. Two linear drive mechanisms synchronously drive the two legs 202 to move. Of course, in other embodiments, two separate legs 202 can also be provided, and the two legs 202 are independently driven by two linear drive mechanisms. When the movable foot 2 is driven to extend and retract, the two linear drive mechanisms drive the two legs 202 to move synchronously.

[0050] Among them, the dictionary pen also includes a main board 5 and a button connected to the main board 5. The button can be pressed and installed on the shell 1. The linear drive mechanism is electrically connected to the main board 5. The main board 5 is used to control the linear drive mechanism based on the pressing signal of the button to drive the movable foot 2 to extend and retract relative to the shell 1.

[0051] The buttons are mechanical buttons, touch buttons, etc. The buttons can be set on the side or front of the housing 1. Preferably, the buttons are mechanical buttons, which are set on the side of the housing 1 to facilitate one-handed operation by the user. Usually, operation keys such as a power button are set on the side of the housing 1. The buttons and operation keys are set on the side of the housing to avoid affecting the overall appearance of the dictionary pen.

[0052] Taking the button as a mechanical button as an example, after a single press, the main board 5 controls the linear drive mechanism to run for a preset time or run until the connecting ear and the limit plate are against each other, so that the movable foot 2 is extended; when use is finished, press the mechanical button again, the main board 5 controls the linear drive mechanism to move in the opposite direction, run for a preset time or run until the inner end of the movable foot and the retaining wall are against each other, so that the movable foot 2 is retracted.

[0053] Each linear drive mechanism is connected to the main board 5 via a connector or a wiring harness 6 .

[0054] In the non-scanning state, the movable foot 2 is housed within the housing 1. To activate scanning, a button is pressed to initiate scanning. The motherboard 5, based on the button's pressure signal, controls the linear drive mechanism to extend the movable foot 2 out of the housing 1 to provide scanning support. To deactivate scanning, the button is pressed again to deactivate scanning. The motherboard 5, based on the button's pressure signal, controls the linear drive mechanism to retract the movable foot 2 back into the housing 1.

[0055] During scanning, the user simply presses a button to control the extension and retraction of the movable foot 2, simplifying the operation process and improving ease of use. When not scanning, the movable foot 2 is housed within the housing, enhancing the overall aesthetics and intelligence of the product. Furthermore, because the extension and retraction of the movable foot 2 are driven by a linear drive mechanism, the movement is smoother and faster, avoiding the shaking and accidental touch problems associated with traditional movable foot designs and improving product stability.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
