Description

Technical Field

[0001] This utility model relates to the field of electronic pen testing technology, and specifically to an electronic pen testing device. Background Technology

[0002] Electronic pens are commonly used tools in the field of intelligent office. Electronic pens establish a communication connection with the screen by pressing the screen. During the application process, the electronic pen and the screen can still maintain a communication connection even if there is a certain distance between them. The electronic pen and the screen can perform some interactions. For example, when the screen detects the electronic pen, the icon of the app that the pen tip is close to will automatically enlarge.

[0003] However, in related technologies, a ruler is usually used to measure the distance from the pen tip to the screen in order to test the communication status between the electronic pen and the screen at a preset height. This method cannot quickly achieve testing within the specified height tolerance, and the hovering height test has low accuracy and efficiency, as well as poor test consistency. Utility Model Content

[0004] In view of this, the present invention provides an electronic pen testing device to solve the problems of low testing accuracy and efficiency, and poor testing consistency of electronic pens under specified height tolerance.

[0005] This utility model provides an electronic pen testing device, comprising: a first base; a sensing module disposed on the first base; a support module disposed on the first base and having a through hole; a limiting block disposed on the support module; and an installation module rotatably passing through the through hole between a first state and a second state, and having a pen mounting hole. The installation module is connected to a rotating handle. When the installation module is in the first state, the rotating handle abuts against the upper surface of the limiting block, and the installation module and the sensing module have a first distance. When the installation module is in the second state, the rotating handle is spaced apart from the limiting block, and the installation module and the sensing module have a second distance. The first distance is greater than the second distance.

[0006] Beneficial Effects: In the second state, the mounting module and the sensing module are at a second distance, with the electronic pen abutting against the sensing module. The electronic pen applies pressure to the sensing module, establishing communication between them. Then, the mounting module is switched to the first state, with the rotating handle abutting against the upper surface of the limiting block. The mounting module and the sensing module are at a first distance, maintaining a preset distance between them. Communication between the electronic pen and the sensing module is still maintained at this state, allowing for testing of the electronic pen by acquiring the sensing signal from the sensing module. By setting the limiting block, the mounting module can be quickly switched to a preset height, thus maintaining a preset distance between the electronic pen and the sensing module. This enables rapid testing of the electronic pen within a specified height tolerance, resulting in high testing accuracy and efficiency, and good test consistency. While increasing production capacity, it also ensures product process quality.

[0007] In one optional embodiment, the limiting block includes: a limiting segment, wherein when the installation module is in the first state, the rotating handle abuts against the upper surface of the limiting segment; a guide segment, wherein the guide segment is connected to the limiting segment, and the height of the upper surface of the guide segment gradually decreases in the direction away from the limiting segment, wherein when the installation module is in the second state, a portion of the upper surface of the guide segment is lower than the rotating handle; and a positioning segment, wherein the positioning segment is connected to the limiting segment and is located on opposite sides of the limiting segment, and the upper surface of the positioning segment is higher than the upper surface of the limiting segment to prevent the rotating handle from detaching from the upper surface of the limiting segment.

[0008] Beneficial effects: When the rotating handle is located on the upper surface of the limiting section, the mounting module and the sensing module are at a first distance, thus ensuring a preset distance between the electronic pen and the sensing module. This allows for rapid testing of the electronic pen's hover pressure sensitivity within a specified height tolerance. In the second state, because the rotating handle is lower than the upper surface of the limiting section, rotating the handle towards the limiting block would cause it to be blocked. Therefore, by setting a guide section, when the rotating handle rotates towards the limiting block, it can rotate onto the upper surface of the guide section. The guide section guides the rotating handle to its position on the upper surface of the limiting section, allowing the mounting module to switch from the second state to the first state. Furthermore, by setting a positioning section, the position of the rotating handle is restricted, preventing it from detaching from the upper surface of the limiting section and ensuring it reliably remains on the upper surface, thus improving the ease of use and reliability of the electronic pen testing device.

[0009] In one optional embodiment, the support module includes: a first support block connected to the first base; a second support block movably connected to the first support block, the second support block being located on the side of the first support block facing away from the first base; and a third support block movably connected to the second support block, the third support block being located on the side of the second support block facing away from the first base; wherein the movement direction of the second support block in the horizontal plane is perpendicular to the movement direction of the third support block in the horizontal plane.

[0010] Beneficial effects: It allows adjustment of the relative positions of the mounting module and the sensing module in two perpendicular directions, thereby adjusting the positions of the electronic pen and the sensing module and optimizing the effect of hover pressure sensitivity testing of the electronic pen.

[0011] In one optional embodiment, the outer peripheral surface of the mounting module is provided with a limiting ring, and when the mounting module is in the second state, the limiting ring abuts against the upper surface of the support module.

[0012] Beneficial effects: When the mounting module is in the second state, the limiting ring can limit the relative position of the mounting module and the support module in the axial direction of the through hole, thereby limiting the mounting module and the sensing module to a second distance. On the one hand, this avoids the electronic pen from excessively pressing the sensing module due to the distance between the mounting module and the sensing module being too small, reducing the probability of damage to the electronic pen and the sensing module. On the other hand, it prevents the distance between the mounting module and the sensing module from being too large, ensuring the pressure between the electronic pen and the sensing module so that an effective communication connection can be formed between the electronic pen and the sensing module.

[0013] In one optional embodiment, the electronic pen testing device further includes a counterweight with a pen tip positioning groove.

[0014] Beneficial effect: It can test the hover pressure sensitivity of electronic pens under preset pressure and preset height tolerance.

[0015] In one optional embodiment, the electronic pen testing device further includes: a base plate; a first pad disposed on the base plate; and a pressure detection element, one end of which is connected to the first pad and the other end of which is supported on the lower surface of the first base.

[0016] Beneficial effects: By setting one end of the pressure detection element to be connected to the base plate through the first pad, and the other end of the pressure detection element to be spaced from the base plate, the pressure detection element will deform under the weight of the first base and the various structures on the first base (including the sensing module, support module, limit block, mounting module, electronic pen and counterweight). The weight of the above components can be obtained by the deformation range of the pressure detection element, and the weight of the counterweight can be determined by the change of the pressure value of the pressure detection element, so as to ensure the accuracy of the test.

[0017] In one optional embodiment, the electronic pen testing device further includes a second pad disposed between the lower surface of the first base and the pressure detection element, the second pad extending beyond the opposite sides in the width direction of the pressure detection element, and the projection of the second pad onto the base plate being located within the projection of the first base onto the base plate.

[0018] Beneficial effects: The smaller contact area between the second pad and the pressure detection element facilitates the application of the weight of the various structures on the first base to the end of the pressure detection element, resulting in better deformation of the pressure detection element and improved accuracy of pressure detection. Furthermore, because the second pad extends beyond the opposite sides of the pressure detection element in the width direction, it increases the contact area between the second pad and the first base, thereby improving the relative stability between the second pad and the first base.

[0019] In one alternative embodiment, the base plate has a groove, the first pad is disposed on the bottom wall of the groove, and at least a portion of the pressure detection element is located within the groove.

[0020] Beneficial effects: On the one hand, it facilitates the fixing of the relative positions of the base plate, the first pad block and the pressure detection component, thereby improving the positioning accuracy. On the other hand, it reduces the height of the electronic pen testing device, which is conducive to the miniaturization of the electronic pen testing device. Furthermore, the maximum deformation range of the pressure detection component is limited, which can reduce the probability of damage to the pressure detection component.

[0021] In one alternative embodiment, the pressure sensing element is provided with a through hole, the axis of which is parallel to the base plate.

[0022] Beneficial effects: It can reduce the structural strength of the pressure detection element, making it easier for the pressure detection element to deform. Under the same pressure, the deformation range of the pressure detection element is greater, which is conducive to improving the reliability of the pressure detection element.

[0023] In one optional embodiment, the electronic pen testing device further includes: a second base disposed on the base plate; a flexible circuit board connected to the sensing module; and a control board connected to the flexible circuit board, wherein the control board is provided with a communication interface.

[0024] Beneficial effects: The control board can acquire signals from the sensing module through the flexible circuit board, determine the communication data between the electronic pen and the sensing module, process the communication data, and then transmit the processed data to the aforementioned electronic device. The test results can be displayed on the screen of the electronic device, so that the user can understand the test situation in a timely manner. Attached Figure Description

[0046] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, an electronic pen testing device 1 is provided. The electronic pen testing device 1 includes a first base 100, a sensing module 200, a mounting module 400, a rotating handle 410, and a limiting block 600.

[0048] The sensing module 200 and the support module 300 are disposed on the first base 100, and the support module 300 is provided with a through hole 301. The mounting module 400 is rotatably disposed through the through hole 301 between the first state and the second state. The mounting module 400 is movable along the axial direction of the through hole 301, and the mounting module 400 is provided with a pen mounting hole 401. The electronic pen 2 is inserted into the pen mounting hole 401. The electronic pen 2 and the mounting module 400 rotate synchronously and move synchronously along the axial direction of the through hole 301.

[0049] The rotating handle 410 is connected to the mounting module 400. When the mounting module 400 is in the first state, the rotating handle 410 abuts against the upper surface of the limiting block 600, and the mounting module 400 and the sensing module 200 have a first distance. At this time, the electronic pen 2 and the sensing module 200 maintain a preset distance. When the mounting module 400 is in the second state, the rotating handle 410 is spaced from the limiting block 600, and the mounting module 400 and the sensing module 200 have a second distance. At this time, the electronic pen 2 and the sensing module 200 abut against each other, and the first distance is greater than the second distance.

[0050] For example, the sensing module 200 can be a screen. The mounting module 400 can be a one-piece structure, and the mounting module 400 has high production efficiency. The mounting module 400 can also be assembled from at least two structures to reduce the processing difficulty of the mounting module 400.

[0051] When the mounting module 400 is in the second state, the mounting module 400 and the sensing module 200 are at a second distance, the electronic pen 2 is in contact with the sensing module 200, the electronic pen 2 applies pressure to the sensing module 200, and communication is established between the electronic pen 2 and the sensing module 200. Then, the mounting module 400 is switched to the first state, the rotating handle 410 is in contact with the upper surface of the limiting block 600, the mounting module 400 and the sensing module 200 are at a first distance, and the electronic pen 2 and the sensing module 200 are maintained at a preset distance. At this time, the electronic pen 2 and the sensing module 200 still maintain communication, and the electronic pen 2 is tested by acquiring the sensing signal of the sensing module 200.

[0052] By setting the limit block 600, the installation module 400 can be quickly switched to a preset height, thereby maintaining a preset distance between the electronic pen 2 and the sensing module 200. This allows for rapid testing of the electronic pen 2 within a specified height tolerance, resulting in high testing accuracy and efficiency, as well as good testing consistency. This improves production capacity while ensuring product manufacturing quality.

[0053] In addition, both the sensing module 200 and the support module 300 are mounted on the first base 100. Compared with mounting the sensing module 200 and the support module 300 on different bases, the probability of misalignment of the sensing module 200 and the support module 300 due to assembly tolerances can be reduced.

[0054] like Figure 2 As shown, in some embodiments, the limiting block 600 includes a limiting segment 610, a guide segment 620, and a positioning segment 630.

[0055] When the mounting module 400 is in the first state, the rotating handle 410 abuts against the upper surface of the limiting section 610. The guide section 620 and the positioning section 630 are both connected to the limiting section 610 and are located on opposite sides of the limiting section 610. The height of the upper surface of the guide section 620 gradually decreases in the direction away from the limiting section 610. When the mounting module 400 is in the second state, part of the upper surface of the guide section 620 is lower than the rotating handle 410. The upper surface of the positioning section 630 is higher than the upper surface of the limiting section 610. When the mounting module 400 is in the first state, the rotating handle 410 is lower than the upper surface of the positioning section 630 to prevent the rotating handle 410 from disengaging from the upper surface of the limiting section 610.

[0056] When the rotating handle 410 is located on the upper surface of the limiting section 610, the mounting module 400 and the sensing module 200 are at a first distance, thereby making the electronic pen 2 and the sensing module 200 at a preset distance, which can quickly realize the hover pressure sensitivity test of the electronic pen 2 within a specified height tolerance.

[0057] When the installation module 400 is in the second state, since the height of the rotating handle 410 is lower than the upper surface of the limiting section 610, rotating the rotating handle 410 towards the limiting block 600 will cause the rotating handle 410 to be stuck by the limiting section 610. Therefore, by setting the guide section 620, when the rotating handle 410 rotates towards the limiting block 600, the rotating handle 410 can rotate onto the upper surface of the guide section 620. The guide section 620 can guide the rotating handle 410 so that the rotating handle 410 can be located on the upper surface of the limiting section 610, thereby enabling the installation module 400 to switch from the second state to the first state.

[0058] In addition, by setting the positioning section 630, the position of the rotating handle 410 can be restricted, preventing the rotating handle 410 from dislodging from the upper surface of the limiting section 610, ensuring that the rotating handle 410 is reliably located on the upper surface of the limiting section 610, and improving the ease of use and reliability of the electronic pen testing device 1.

[0059] like Figures 1-3 As shown, in some embodiments, the support module 300 includes a first support block 310, a second support block 320, and a third support block 330.

[0060] The first support block 310 is connected to the first base 100. The second support block 320 is movably connected to the first support block 310, and the second support block 320 is located on the side of the first support block 310 facing away from the first base 100. The third support block 330 is movably connected to the second support block 320, and the third support block 330 is located on the side of the second support block 320 facing away from the first base 100. The direction of movement of the second support block 320 in the horizontal plane is perpendicular to the direction of movement of the third support block 330 in the horizontal plane.

[0061] Specifically, there can be two first support blocks 310, arranged parallel to each other and spaced apart along the width direction of the first support blocks 310. There can also be two second support blocks 320, each mounted on one of the first support blocks 310. The second support blocks 320 are parallel to the first support blocks 310 and may have an oblong hole, the extension direction of which is either the same as or perpendicular to the extension direction of the second support block 320. A third support block 330 can be connected to both second support blocks 320 simultaneously. The third support block 330 may have an oblong hole, the extension direction of which is perpendicular to the extension direction of the oblong hole in the second support block 320.

[0062] In this way, the relative positions of the mounting module 400 and the sensing module 200 can be adjusted in two perpendicular directions, thereby adjusting the positions of the electronic pen 2 and the sensing module 200 and optimizing the effect of the hover pressure sensitivity test of the electronic pen 2.

[0063] like Figures 4-5 As shown, in some embodiments, the outer peripheral surface of the mounting module 400 is provided with a limiting ring 402, and when the mounting module 400 is in the second state, the limiting ring 402 abuts against the upper surface of the support module 300.

[0064] By setting a limiting ring 402, when the mounting module 400 is in the second state, the relative position of the mounting module 400 and the support module 300 in the axial direction of the through hole 301 can be limited, thereby limiting the mounting module 400 and the sensing module 200 to a second distance. On the one hand, this avoids the electronic pen 2 from excessively pressing the sensing module 200 due to the distance between the mounting module 400 and the sensing module 200 being too small, reducing the probability of damage to the electronic pen 2 and the sensing module 200. On the other hand, it prevents the distance between the mounting module 400 and the sensing module 200 from being too large, ensuring the pressure between the electronic pen 2 and the sensing module 200 so that an effective communication connection can be formed between the electronic pen 2 and the sensing module 200.

[0065] like Figures 1-5 As shown, in some embodiments, the electronic pen testing device 1 further includes a counterweight 500, which has a pen tip positioning groove 510.

[0066] In other words, the tip of the electronic pen 2 is inserted into the pen tip positioning groove 510 to fix the relative position between the electronic pen 2 and the counterweight 500. When the mounting module 400 is in the second state, the electronic pen 2 presses against the sensing module 200. The pressure on the electronic pen 2 is the sum of the weight of the electronic pen 2 itself and the weight of the counterweight 500. When the mounting module 400 is switched to the first state, the sensing signal between the electronic pen 2 and the sensing module 200 is detected. In this way, the hovering pressure sensitivity of the electronic pen 2 can be tested under preset pressure and preset height tolerance.

[0067] In addition, there can be multiple counterweights 500, and the weights of the multiple counterweights 500 are different, which can simulate different pressures applied by the user. By switching the counterweights 500 on the top of the electronic pen 2, the pressure of the electronic pen 2 on the sensing module 200 is different, and thus the pressure on the electronic pen 2 is different. It is possible to test the hovering pressure sensitivity of the electronic pen 2 under different pressures and preset height tolerances, and the pressure compatibility is strong.

[0068] Furthermore, the electronic pen testing device 1 also includes a base plate 700, a first pad 810, and a pressure detection element 800. The first pad 810 is disposed on the base plate 700, one end of the pressure detection element 800 is connected to the first pad 810, and the other end is supported on the lower surface of the first base 100.

[0069] Among them, the pressure detection element 800 can be a pressure sensor.

[0070] By setting one end of the pressure detection element 800 to be connected to the base plate 700 through the first pad 810, and the other end of the pressure detection element 800 to be spaced from the base plate 700, the pressure detection element 800 will deform under the weight of the first base 100 and the various structures on the first base 100 (including the sensing module 200, support module 300, limit block 600, mounting module 400, electronic pen 2 and counterweight 500). The weight of the above-mentioned components can be obtained by the deformation range of the pressure detection element 800, and the weight of the counterweight 500 can be determined by the change in the pressure value of the pressure detection element 800, so as to ensure the accuracy of the test.

[0071] Furthermore, the pressure sensing element 800 is provided with a through hole 801, the axis of which is parallel to the base plate 700, and the through hole 801 is located at the center of the length direction of the pressure sensing element 800. This reduces the structural strength of the pressure sensing element 800, facilitates deformation, and allows for a larger deformation range under the same pressure, thus improving the reliability of the pressure sensing element 800.

[0072] like Figures 4-5As shown, in some embodiments, the electronic pen testing device 1 further includes a second pad 820, which is disposed between the lower surface of the first base 100 and the other end of the pressure detection element 800. The second pad 820 extends beyond the opposite sides of the pressure detection element 800 in the width direction, and the projection of the second pad 820 on the base plate 700 is located within the projection of the first base 100 on the base plate 700.

[0073] Since the projection of the second pad 820 on the base plate 700 is within the projection of the first base 100 on the base plate 700, the contact area between the second pad 820 and the pressure detection element 800 is smaller than that between the first base 100 and the pressure detection element 800. This is beneficial for applying the weight of each structure on the first base 100 to the end of the pressure detection element 800, resulting in better deformation of the pressure detection element 800 and improved accuracy of pressure detection.

[0074] In addition, since the second pad 820 extends beyond the opposite sides of the pressure detection element 800 in the width direction, the contact area between the second pad 820 and the first base 100 can be increased, thereby improving the relative stability between the second pad 820 and the first base 100.

[0075] like Figures 4-5 As shown, in some embodiments, the base plate 700 is provided with a groove 710, the first pad 810 is provided on the bottom wall of the groove 710, and at least a portion of the pressure detection element 800 is located in the groove 710.

[0076] In this way, on the one hand, it is convenient to fix the relative position of the base plate 700, the first pad 810 and the pressure detection element 800, thereby improving the positioning accuracy; on the other hand, it can reduce the height of the electronic pen testing device 1, which is conducive to the miniaturization of the electronic pen testing device 1, and the maximum deformation range of the pressure detection element 800 is limited, which can reduce the probability of damage to the pressure detection element 800.

[0077] like Figures 1-5 As shown, in some embodiments, the electronic pen testing device 1 further includes a second base 900, a flexible printed circuit board (FPC) 910, and a control board 920. The second base 900 is disposed on the base plate 700. The flexible printed circuit board 910 is connected to the sensing module 200. The control board 920 is connected to the flexible printed circuit board 910. The control board 920 is provided with a communication interface 930. The control board 920 can communicate with electronic devices such as host computers, industrial control computers, or laptops through the communication interface 930. The aforementioned electronic devices can input different control programs to the control board 920.

[0078] The control board 920 can acquire the signal from the sensing module 200 through the flexible circuit board 910, and can determine the communication data between the electronic pen 2 and the sensing module 200. The control board 920 processes the communication data and then transmits the processed data to the aforementioned electronic device. The test results can be displayed on the screen of the electronic device so that the user can understand the test situation in a timely manner.

[0079] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
