Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technology, specifically relating to an electronic pen and electronic device components. Background Technology
[0002] With the rapid growth of smartphones, tablets, and smart notebooks, more and more applications require higher precision touch, such as drawing software. As a result, the use of electronic pens has become increasingly widespread, and the requirements for the performance and user experience of electronic pens are also getting higher and higher.
[0003] In the prior art, an electronic pen includes a pen barrel, a pen tip, a collapsible mechanism, and a sensor. The pen tip is disposed inside the pen barrel and can extend out of the end of the pen barrel. The collapsible mechanism is disposed inside the pen barrel and connected to the side of the pen tip away from the pen barrel. The sensor is connected to the side of the collapsible mechanism away from the pen tip. When the pen tip is subjected to a large external force impact, the collapsible mechanism absorbs the impact force, thereby reducing the impact on the sensor.
[0004] However, the existing collapse mechanism is a rigid structure, which is not good at buffering the impact on the sensor. Furthermore, in scenarios such as when the electronic pen is dropped or accidentally flies out, the collapse mechanism is easily damaged and cannot be restored when the external force on the pen tip is too great, thus failing. Utility Model Content
[0005] In view of the above problems, this utility model is proposed to provide an electronic pen and electronic device component that overcomes or at least partially solves the above problems.
[0006] To solve the above-mentioned technical problems, this application is implemented as follows:
[0007] In a first aspect, embodiments of this application provide an electronic pen, the electronic pen comprising: a pen barrel and a pen tip, a sensor, and a flexible buffer disposed within the pen barrel;
[0008] The pen tip is disposed at the end of the pen holder, and one end of the pen tip can extend out of the end of the pen holder;
[0009] The sensor is connected to the other end of the pen tip;
[0010] The flexible buffer is connected to the side of the sensor away from the pen tip, and the flexible buffer has a buffer groove on the side closer to the sensor.
[0011] The buffer groove includes a first buffer groove and a second buffer groove;
[0012] The first buffer groove is disposed in the middle region of the flexible buffer member, and the second buffer groove is disposed on the outer periphery of the first buffer groove.
[0013] Optionally, the number of the second buffer slots may include multiple slots, which are spaced apart around the first buffer slot.
[0014] Optionally, the plurality of second buffer grooves are respectively a first groove, a second groove, a third groove and a fourth groove, wherein the first groove, the second groove, the third groove and the fourth groove are spaced apart in the circumferential direction of the first buffer groove.
[0015] Optionally, the first buffer groove is a rectangular buffer groove, and the top corner of the rectangular buffer groove is provided with a first arc-shaped transition surface.
[0016] Optionally, the second buffer groove is disposed on the outer periphery of the rectangular buffer groove, and the side of the second buffer groove close to the rectangular buffer groove is provided with a second arc-shaped transition surface, and the side of the second buffer groove away from the rectangular buffer groove is provided with a third arc-shaped transition surface.
[0017] Optionally, the second buffer groove is L-shaped.
[0018] Optionally, the first buffer groove and the second buffer groove are recessed away from the sensor.
[0019] Optionally, the depth of the first buffer groove is any value between 0.1 and 0.35 mm;
[0020] The depth of the second buffer groove is any value between 0.1 and 0.35 mm.
[0021] Optionally, the electronic pen further includes a bracket connected to the other end of the pen tip, and the sensor is connected to the bracket.
[0022] Secondly, embodiments of this application provide an electronic device component, which includes an electronic device and the electronic pen.
[0023] In this embodiment, the electronic pen includes: a pen barrel and a pen tip, a sensor, and a flexible buffer disposed within the pen barrel; the pen tip is disposed at the end of the pen barrel, and one end of the pen tip can extend out of the end of the pen barrel; the sensor is connected to the other end of the pen tip; the flexible buffer is connected to the side of the sensor away from the pen tip, and the flexible buffer has a buffer groove on the side of the flexible buffer close to the sensor; the first buffer groove is disposed in the middle region of the flexible buffer, and the second buffer groove is disposed on the outer periphery of the first buffer groove. Thus, when the pen tip is impacted by an external force, the impact force is transmitted along the sensor to the flexible buffer. The deformation of the flexible buffer with the buffer groove absorbs the impact force on the sensor. Specifically, the structural strength at the first and second buffer grooves is lower, making them more susceptible to compression and deformation. Furthermore, the first buffer groove in the middle region and the second buffer groove around the periphery provide good deformation energy absorption at both the middle and periphery of the flexible buffer, enhancing the buffering effect and improving the overall buffering performance, thereby achieving a better buffering effect on the sensor. This design avoids the poor impact cushioning effect of rigid collapsible mechanisms on the sensor, and also prevents the collapsible mechanism from being easily damaged and failing when the pen tip is subjected to excessive external force in scenarios such as the pen being dropped or accidentally thrown. Furthermore, since the sensor typically has sensing protrusions on the side near the pen tip, connecting the flexible buffer to the side of the sensor away from the pen tip prevents the sensing protrusions on the sensor from exerting excessive pressure on a localized area of the flexible buffer, which would be detrimental to the overall cushioning effect, thus improving the sensor's cushioning performance.

[0033] Reference Figures 1 to 2This diagram illustrates the structure of an electronic pen and a flexible buffer according to an embodiment of this application. The electronic pen specifically includes: a pen barrel 10 and a pen tip 20, a sensor 30, and a flexible buffer 40 disposed within the pen barrel 10; the pen tip 20 is disposed at the end of the pen barrel 10, and one end of the pen tip 20 can extend out of the end of the pen barrel 10; the sensor 30 is connected to the other end of the pen tip 20; the flexible buffer 40 is connected to the side of the sensor 30 away from the pen tip 20, and a buffer groove is provided on the side of the flexible buffer 40 close to the sensor 30; the buffer groove includes a first buffer groove 41 and a second buffer groove 42; the first buffer groove 41 is disposed in the middle region of the flexible buffer 40, and the second buffer groove 42 is disposed on the outer periphery of the first buffer groove 41.
[0034] In this embodiment, when the pen tip 20 is impacted by an external force, the impact force is transmitted along the sensor 30 to the flexible buffer 40. The flexible buffer 40, which has buffer grooves, deforms to absorb the impact force on the sensor 30. Specifically, the structural strength of the first buffer groove 41 and the second buffer groove 42 is lower, making them more susceptible to compression and deformation. Furthermore, the first buffer groove 41 located in the middle region and the second buffer groove 42 located around the perimeter ensure that both the middle and perimeter positions of the flexible buffer 40 have good deformation energy absorption effects, enhancing the buffering force of the flexible buffer 40 and improving the buffering effect, thereby achieving a better buffering effect on the sensor 30. This avoids the poor impact buffering effect of using a rigid collapse mechanism on the sensor 30, and also avoids the problem that the collapse mechanism is easily damaged and cannot be repaired when the external force impact on the pen tip 20 is too large in scenarios such as the electronic pen being dropped or accidentally flying out. Furthermore, since the sensor 30 usually has a sensing protrusion on the side near the pen tip 20, the flexible buffer 40 is connected to the side of the sensor 30 away from the pen tip 20. This avoids the sensing protrusion on the sensor 30 exerting excessive pressure on a local area of the flexible buffer 40, which would be detrimental to the overall buffering effect and improves the buffering performance of the sensor 30.
[0035] For example, in this embodiment of the application, the pen holder 10 may also be provided with an abutment portion, and the side of the flexible buffer 40 away from the sensor 30 abuts against the abutment portion. The abutment portion provides support for the flexible buffer 40 and prevents the flexible buffer 40 from displacing in a direction away from the sensor 30.
[0036] In this embodiment, for example, the flexible buffer 40 covers the side of the sensor 30 away from the pen tip 20. That is, the size of the flexible buffer 40 can be equal to or larger than the size of the sensor 30. This allows the flexible buffer 40 to have a larger contact area with the sensor 30, thereby providing a larger buffering area and improving the buffering effect. This avoids the situation where a small size of the flexible buffer 40 would reduce the buffering effect on the sensor 30.
[0037] In this embodiment, the flexible buffer 40 is flexible and capable of elastic deformation. When the flexible buffer 40 undergoes elastic deformation, it can absorb impact force and provide cushioning. For example, the flexible elastic member can be silicone, rubber, or other soft plastic structures; the material of the flexible elastic member is not limited in this embodiment. For example, the shape of the flexible elastic member can be rectangular, square, circular, or elliptical, etc., and can be set according to the specific structure and shape requirements of the electronic pen; the specific shape of the flexible elastic member is not limited in this embodiment.
[0038] For example, in this embodiment, the thickness of the flexible buffer 40 can be any value between 1.01 and 1.15 mm, or 1 mm or 1.2 mm, etc. This embodiment does not limit the specific value of the thickness of the flexible buffer 40. The length of the flexible buffer 40 can be any value between 3.4 and 3.5 mm, or 3 mm or 3.6 mm, etc. This embodiment does not limit the specific value of the length of the flexible buffer 40. The width of the flexible buffer 40 can also be any value between 3.4 and 3.5 mm, or 3 mm or 3.6 mm, etc. This embodiment does not limit the specific value of the width of the flexible buffer 40.
[0039] Specifically, in this embodiment, the pen holder 10 can be a hollow cylinder for the user to hold, and the hollow cavity provides space for structures such as the pen tip 20, sensor 30, and flexible buffer 40. One end of the pen tip 20 can extend out of the end of the pen holder 10, enabling interaction with the screen of an electronic device for writing or drawing. The sensor 30 can sense and detect the pressure on the pen tip 20. For example, the sensor 30 can be a pressure sensor, a pressure transducer, etc. The specific type of sensor 30 is not limited in this embodiment.
[0040] For example, in this embodiment, the first buffer groove 41 and the second buffer groove 42 are groove structures. The shape of the first buffer groove 41 can be square, rectangular, circular, or elliptical, etc., and can be set according to actual needs and test results. This embodiment does not limit the specific shape of the first buffer groove 41. Similarly, the shape of the second buffer groove 42 can be arc-shaped, L-shaped, or V-shaped, etc., and can be set according to actual needs and test results. This embodiment also does not limit the specific shape of the second buffer groove 42.
[0041] In this embodiment, optionally, the number of second buffer grooves 42 includes multiple second buffer grooves 42, which are spaced apart around the first buffer groove 41. This allows for further differentiation of the circumferential buffering force of the flexible buffer member 40 through multiple second buffer grooves 42. Furthermore, the size of each second buffer groove 42 can be set according to the actual force effect, thereby achieving more precise control over the buffering and energy absorption effect of the flexible buffer member 40 and improving the buffering effect.
[0042] Specifically, in this embodiment, multiple second buffer slots 42 are spaced apart, and a partition wall is formed between adjacent second buffer slots 42. Furthermore, for example, multiple second buffer slots 42 can be interconnected to form a single, integrated second buffer slot 42. The specific arrangement of the second buffer slots 42 is not limited in this embodiment.
[0043] Optionally, in this embodiment, the plurality of second buffer grooves 42 are respectively a first groove 43, a second groove 44, a third groove 45, and a fourth groove 46, and the first groove 43, the second groove 44, the third groove 45, and the fourth groove 46 are spaced apart in the circumferential direction of the first buffer groove 41. Figure 2 As shown, the outer periphery of the first buffer groove 41 may be provided with four second buffer grooves 42, namely the first groove 43, the second groove 44, the third groove 45 and the fourth groove 46, which buffer and absorb energy in the surrounding area of the flexible buffer member 40 through the first groove 43, the second groove 44, the third groove 45 and the fourth groove 46.
[0044] Optionally, in this embodiment, the first buffer groove 41 is a rectangular buffer groove, and the apex corner of the rectangular buffer groove is provided with a first arc-shaped transition surface 47. For example... Figure 2 As shown, the first buffer groove 41 is set as a rectangular buffer groove, that is, it is a square or rectangle with four apex corners. Four first arc-shaped transition surfaces 47 are set at the four apex corners respectively to avoid the four apex corners being sharp corner structures, which are prone to cracking or damage during multiple stress deformation processes, thus extending the service life of the flexible buffer 40.
[0045] Optionally, in this embodiment, the second buffer groove 42 is disposed on the outer periphery of the rectangular buffer groove, the side of the second buffer groove 42 closest to the rectangular buffer groove is provided with a second arc-shaped transition surface 48, and the side of the second buffer groove 42 furthest from the rectangular buffer groove is provided with a third arc-shaped transition surface 49. Figure 2As shown, to adapt to the shape and structure of the rectangular buffer groove, the second buffer groove 42 can be L-shaped. A second arc-shaped transition surface 48 and a third arc-shaped transition surface 49 are respectively provided on the side of the second buffer groove 42 close to the rectangular buffer groove and the side away from the rectangular buffer groove, so as to avoid the second buffer groove 42 having a sharp corner structure, and prevent cracking or damage due to the sharp corner of the second buffer groove 42 during multiple stress deformation processes, thereby further extending the service life of the flexible buffer 40.
[0046] Optionally, in this embodiment, the first buffer groove 41 and the second buffer groove 42 are recessed away from the sensor 30. When the pen tip 20 is impacted by an external force, the impact force is transmitted along the pen tip 20 from the sensor 30 to the flexible buffer member 40. Therefore, by setting the first buffer groove 41 and the second buffer groove 42 to be recessed away from the sensor 30, the side of the flexible buffer member 40 closest to the sensor 30 is more likely to deform and absorb energy, thus achieving a more timely and effective buffering effect on the impact force transmitted from the sensor 30 to the flexible buffer member 40.
[0047] Optionally, in this embodiment, the depth of the first buffer groove 41 is any value between 0.1 and 0.35 mm; the depth of the second buffer groove 42 is any value between 0.1 and 0.35 mm. This avoids the situation where a shallow depth of the first buffer groove 41 results in a high hardness of the flexible buffer member 40, leading to poor energy absorption and buffering effects, and also avoids the situation where a deep depth of the first buffer groove 41 results in a low hardness of the flexible buffer member 40, also leading to poor energy absorption and buffering effects. Experimental tests show that when the depth of the first buffer groove 41 is set to 0.1 mm, 0.15 mm, 0.24 mm, and 0.35 mm, the middle position of the flexible buffer member 40 provides a good buffering and energy absorption effect for the sensor 30. Furthermore, the depth of the first buffer groove 41 can also be set to 0.18 mm, 0.2 mm, and 0.4 mm, etc., as needed. The specific depth of the first buffer groove 41 is not limited in this embodiment.
[0048] Similarly, the depth of the second buffer groove 42 can be set to any value between 0.1 and 0.35 mm. This avoids the situation where a shallow depth of the second buffer groove 42 results in a high rigidity of the flexible buffer member 40, leading to poor energy absorption and buffering effects, and conversely, a deep depth of the second buffer groove 42 results in a low rigidity of the flexible buffer member 40, also leading to poor energy absorption and buffering effects. Tests have shown that when the depth of the second buffer groove 42 is set to 0.1 mm, 0.15 mm, 0.24 mm, and 0.35 mm, the perimeter of the flexible buffer member 40 provides good energy absorption and buffering effects for the sensor 30. Furthermore, the depth of the second buffer groove 42 can also be set to 0.18 mm, 0.2 mm, and 0.4 mm, etc., depending on actual needs. The specific depth of the second buffer groove 42 in this embodiment is not limited.
[0049] Optionally, in this embodiment, the electronic pen further includes a support 21 connected to the other end of the pen tip 20, and the sensor 30 connected to the support 21. This provides a more stable and reliable support for the pen tip 20 through the support 21, and also connects the pen tip 20 to the sensor 30, preventing the other end of the pen tip 20 from being directly connected to the sensor 30, which would affect the sensor 30's sensing reliability due to its small end size. For example, the electronic pen may also include a spring connected to both the support 21 and the inner wall of the pen barrel 10, providing elastic cushioning for the pen tip 20. The specific structure and arrangement of the spring are not limited in this embodiment.
[0050] In summary, the electronic pen described in this application embodiment has at least the following advantages:
[0051] In this embodiment, the electronic pen includes: a pen barrel and a pen tip, a sensor, and a flexible buffer disposed within the pen barrel; the pen tip is disposed at the end of the pen barrel, and one end of the pen tip can extend out of the end of the pen barrel; the sensor is connected to the other end of the pen tip; the flexible buffer is connected to the side of the sensor away from the pen tip, and the flexible buffer has a buffer groove on the side of the flexible buffer close to the sensor; the first buffer groove is disposed in the middle region of the flexible buffer, and the second buffer groove is disposed on the outer periphery of the first buffer groove. Thus, when the pen tip is impacted by an external force, the impact force is transmitted along the sensor to the flexible buffer. The deformation of the flexible buffer with the buffer groove absorbs the impact force on the sensor. Specifically, the structural strength at the first and second buffer grooves is lower, making them more susceptible to compression and deformation. Furthermore, the first buffer groove in the middle region and the second buffer groove around the periphery provide good deformation energy absorption at both the middle and periphery of the flexible buffer, enhancing the buffering effect and improving the overall buffering performance, thereby achieving a better buffering effect on the sensor. This design avoids the poor impact cushioning effect of rigid collapsible mechanisms on the sensor, and also prevents the collapsible mechanism from being easily damaged and failing when the pen tip is subjected to excessive external force in scenarios such as the pen being dropped or accidentally thrown. Furthermore, since the sensor typically has sensing protrusions on the side near the pen tip, connecting the flexible buffer to the side of the sensor away from the pen tip prevents the sensing protrusions on the sensor from exerting excessive pressure on a localized area of the flexible buffer, which would be detrimental to the overall cushioning effect, thus improving the sensor's cushioning performance.
[0052] This application also proposes an electronic device component, which includes an electronic device and the electronic pen.
[0053] For example, in this application embodiment, the electronic device may be any one of mobile phones, tablets, and wearable devices, and the specific type of the electronic device may not be limited in this application embodiment.
[0054] In this embodiment, the pen tip 20 of the electronic pen can sense and detect the screen of the electronic device and interact with it, thereby activating a writing or drawing mode. For example, the pen tip 20 can interact with the screen of the electronic device via the USI (Universal Serial Interface) protocol or the MPP (Message Posting Protocol). Furthermore, the pen tip 20 can also interact with the screen of the electronic device via other protocols; this embodiment does not limit the specific protocols used.
[0055] The electronic device components described in the embodiments of this application may include at least the following advantages:
[0056] In this embodiment, the electronic device component includes an electronic device and the electronic pen. The electronic pen includes a pen barrel and a pen tip, a sensor, and a flexible buffer disposed within the pen barrel. The pen tip is disposed at the end of the pen barrel, and one end of the pen tip can extend beyond the end of the pen barrel. The sensor is connected to the other end of the pen tip. The flexible buffer is connected to the side of the sensor away from the pen tip, and a buffer groove is provided on the side of the flexible buffer near the sensor. The first buffer groove is disposed in the middle region of the flexible buffer, and the second buffer groove is disposed on the outer periphery of the first buffer groove. Thus, when the pen tip is impacted by an external force, the impact force is transmitted along the sensor to the flexible buffer. The flexible buffer with the buffer groove deforms and absorbs the impact force on the sensor. Specifically, the structural strength at the first and second buffer grooves is lower and more susceptible to compression and deformation. Furthermore, the first buffer groove in the middle region and the second buffer groove around the periphery provide good deformation energy absorption at both the middle and periphery of the flexible buffer, enhancing the buffering effect of the flexible buffer and improving the buffering effect, thereby achieving a better buffering effect on the sensor. This design avoids the poor impact cushioning effect of rigid collapsible mechanisms on the sensor, and also prevents the collapsible mechanism from being easily damaged and failing when the pen tip is subjected to excessive external force in scenarios such as the pen being dropped or accidentally thrown. Furthermore, since the sensor typically has sensing protrusions on the side near the pen tip, connecting the flexible buffer to the side of the sensor away from the pen tip prevents the sensing protrusions on the sensor from exerting excessive pressure on a localized area of the flexible buffer, which would be detrimental to the overall cushioning effect, thus improving the sensor's cushioning performance.
