Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of electronic devices, and in particular to a touch module and an electronic device. Background Art
[0002] Some of the existing laptops use a stylus to touch the screen. The existing stylus mainly uses the direct sliding friction and mutual interference between the conductive sheet and the outer wall of the stylus to maintain the contact stability between the conductive sheet and the stylus during charging. In actual application, since it is difficult to require the user to insert the stylus relative to the laptop, it is very easy to insert the stylus relative to the conductive sheet of the touch module crookedly. For example, the stylus is inserted obliquely into the slot. If the stylus is inserted crookedly, the conductive sheet will be deformed by overpressure or even cannot be reset, which will cause the conductive sheet to be crushed and the stylus cannot be charged.

DETAILED DESCRIPTION
[0022] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0023] With the widespread application of electronic devices, the research and development direction of the performance of various components or structural parts in electronic devices has become more and more extensive. According to different functions, there are various types of electronic devices, one of which uses a stylus for touch screen operation. The structure involved in this part of the function is generally a touch module. The touch module currently used mainly relies on the radial pressure between the special-shaped conductive sheet and the outer wall of the stylus and the sliding friction in the axial direction during the insertion of the stylus to achieve the stable insertion of the stylus in the touch module and the electrical connection and charging of the stylus. However, in actual application, since it is difficult to require users to insert the stylus relative to the laptop computer, it is very easy to insert the stylus relative to the conductive sheet of the touch module crookedly. You can refer to the situation where the stylus is inserted obliquely into the slot. After the stylus is inserted crookedly, it will cause the conductive sheet to be over-pressure deformed or even unreset, which will cause the conductive sheet to be crushed and unable to charge the stylus.
[0024] In order to alleviate the above problems, the embodiments of the present disclosure provide a touch module, which can avoid sliding friction between the conductive sheet and the outer wall of the stylus pen when the stylus pen is inserted into the touch module, thereby increasing the service life of the conductive sheet and completing normal charging of the stylus pen in the touch module.
[0025] refer to Figure 1 and Figure 2 The embodiment of the present disclosure provides a touch module 001, including: a circuit board 10. The touch module 001 is generally used in conjunction with a stylus 50. The outer wall of the stylus 50 has a preset path 51. When the stylus 50 is inserted into the touch module 001, the rolling element 20 can roll along the preset path 51 of the outer wall of the stylus 50. It should be noted that a step height is formed between the initial position of the rolling element 20 and the preset path 51. The preset path 51 is higher than the initial position of the rolling element 20, and the step height does not hinder the rolling of the rolling element 20 along the preset path 51. The embodiment of the present disclosure does not limit the curvature of the preset path 51, which can be a flat path or a continuous curved path with convex and concave settings. Taking the preset path 51 as a continuous curved path with convex and concave settings as an example, when the rolling element 20 rolls along the preset path 51, the rolling element 20 can perform a resettable approaching motion or a moving away motion relative to the circuit board 10.
[0026] Specifically, the touch module 001 of the embodiment of the present disclosure further includes a hollow telescopic rod 60 and a spring, the spring is sleeved inside the telescopic rod 60, and the telescopic rod 60 can be highly telescopic along its own height direction; the rolling element 20 is connected to the movable end of the telescopic rod 60, and one end of the spring is connected to the rolling element 20, and the other end of the spring is insulatedly connected to the circuit board 10. In this way, the rolling element 20 can achieve a resettable approaching or moving away movement relative to the circuit board 10, which can also be understood as achieving an upward or downward movement of the rolling element 20 relative to the circuit board 10.
[0027] The touch module 001 of the disclosed embodiment further includes a conductive sheet 40, which is used to electrically connect the circuit board 10 with the stylus 50 to ensure charging of the stylus 50. Exemplarily, the proximal end of the conductive sheet 40 is directly electrically connected to the circuit board 10.
[0028] Considering that the distal end of the conductive sheet 40 can follow the telescopic movement of the telescopic rod 60 to be compressed and deformed toward the stylus 50, and then during the process of the conductive sheet 40 being compressed and deformed, at least a part of the structure of the conductive sheet 40 is electrically connected to the charging area of the stylus 50, so that the conductive sheet 40 can connect the stylus 50 and the circuit board 10. The touch module 001 of the disclosed embodiment also includes a connecting plate 80 and an adapter 30. The connecting plate 80 is connected to the outer wall of the telescopic rod 60. The connecting plate 80 can move up and down following the telescopic movement of the telescopic rod 60. The connecting plate 80 has a first fulcrum 70. The first fulcrum 70 is configured to maintain a preset height distance with the rolling element 20 during the telescopic movement of the telescopic rod 60. During the movement of the connecting plate 80, the connecting plate 80 maintains a preset height distance with the rolling element 20. The touch module 001 has a second fulcrum 90. The second fulcrum 90 is located between the circuit board 10 and the first fulcrum 70. The adapter 30 rotates Connected to the second fulcrum 90; the adapter 30 is rotatably located between the circuit board 10 and the rolling element 20, and the adapter 30 can move with the upward or downward movement of the rolling element 20; specifically, the adapter 30 includes a rotating portion 33 and a first connecting arm 31 and a second connecting arm 32 formed by extending the outer wall of the rotating portion 33, the first connecting arm 31 and the second connecting arm 32 are staggered, and the angle between the two connecting arms is less than 180°; wherein the first connecting arm 31 overlaps the upper surface of the connecting plate 80 (that is, above the first fulcrum 70), and the second connecting arm 32 overlaps the upper end of the conductive sheet 40. In this way, the adapter 30 can provide a resettable pressing force to the distal end of the conductive sheet 40 during the rotation process, so that the conductive sheet 40 maintains an electrical connection with the charging area of the stylus 50 during the compression deformation process. Specifically, the first connecting arm 31 rotates clockwise under the upward pushing pressure of the connecting plate 80, so that the second connecting arm 32 rotates clockwise synchronously. Since the second connecting arm 32 is overlapped above the distal end of the conductive sheet 40, the second connecting arm 32 applies a pressing force toward the direction of the stylus 50 to the distal end of the conductive sheet 40 during the clockwise rotation. Exemplarily, the conductive sheet 40 can be a metal spring sheet with conductive properties, which adopts a special-shaped structure, and the metal spring sheet has a structure protruding toward the stylus 50. In this way, under the action of the pressing force of the conductive sheet 40 toward the stylus 50, the protruding structure can move toward the stylus 50. When the pressing force along the radial direction of the stylus 50 itself is formed between the protruding structure and the stylus 50, under the joint action of the spring and the telescopic rod 60, the rolling element 20 applies radial pressure to the stylus 50. At the same time, combined with the radial pressing force applied by the conductive sheet 40 to the stylus 50, the stylus 50 maintains a stable charging state in the touch module 001.
[0029] Exemplarily, the conductive sheet 40 further includes a plane portion 41 and a curved portion 42, wherein the plane portion 41 is connected to the proximal end of the conductive sheet 40, the plane portion 41 is connected to the distal end of the conductive sheet 40 through the curved portion 42, and the conductive sheet 40 is electrically connected to the stylus 50 through the curved portion 42; the curved portion 42 includes a first sub-portion 421 and a second sub-portion 422 arranged at an acute angle, the first sub-portion 421 and the second sub-portion 422 are both constructed as a plane structure, the first sub-portion 421 is connected to the distal end, and the second sub-portion 422 is connected to the proximal end through the plane portion 41. The structure in which the conductive sheet 40 protrudes toward the stylus 50 is formed between the first sub-portion 421 and the second sub-portion 422. By constructing the first sub-portion 421 and the second sub-portion 422 as a plane structure, the preset height distance of the conductive sheet 40 relative to the stylus 50 can be increased, so that the stylus 50 can be smoothly inserted relative to the touch module 001.
[0030] Specifically, the touch module 001 of the embodiment of the present disclosure further includes a fixing member 100, which is installed on the side of the circuit board 10 close to the rolling member 20, and the second fulcrum 90 is formed on the fixing member 100. The fixing member 100 has a first accommodating space 101 and a second accommodating space 102 connected to the first accommodating space 101. The first accommodating space 101 is used to install the rolling member 20 and the adapter 30. The conductive sheet 40 is installed in the second accommodating space 102, and the second accommodating space 102 is used to guide along the length direction of the conductive sheet 40. Exemplarily, the second accommodating space 102 is constructed as a long strip through-hole structure, which can guide the conductive sheet 40 to prevent the conductive sheet 40 from offsetting when it is deformed toward the stylus 50.
[0031] In addition, an embodiment of the present disclosure further provides an electronic device, including the aforementioned touch module 001, the touch module 001 rolls along a preset path 51 on the stylus 50 on the rolling element 20, and the conductive sheet 40 is electrically connected to the charging area of the stylus 50 during the compression deformation process.
[0032] In this way, using the touch module 001 and the electronic device of the disclosed embodiment, when the stylus 50 is inserted into the touch module 001, the rolling element 20 can roll along the preset path 51 on the stylus 50. The preset path 51 has a height difference relative to the initial position of the rolling element 20, which is equivalent to the rolling element 20 rolling on the step surface. During the rolling process, the rolling element 20 will move closer to or away from the circuit board 10. At this time, the adapter 30 can rotate following the upward or downward movement of the rolling element 20. During the rotation, the adapter 30 provides a resettable pressing force to the far end of the conductive sheet 40. In this way, the conductive sheet 40 can maintain an electrical connection with the charging area of the stylus 50 during the compression deformation process. By adopting this solution, the relative rolling between the rolling element 20 and the stylus pen 50 can be used to achieve the insertion movement of the stylus pen 50 with less friction and wear, avoiding the insertion method that solely relies on the sliding friction between the conductive sheet 40 and the stylus pen 50. It can reduce the sliding wear between the conductive sheet 40 and the stylus pen 50, and can also prevent the stylus pen 50 from being inserted crookedly when the rolling element 20 and the conductive sheet 40 press the stylus pen 50 at the same time, thereby avoiding irreversible over-pressure deformation of the conductive sheet 40.
[0033] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved, and this document does not limit this.
[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0035] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
