Description

Technical Field

[0001] The utility model belongs to the technical field of touch panels, in particular to a touch panel module capable of full-area pressing. Background Art

[0002] Electronic devices such as laptops are developing towards being lighter, thinner, more user-friendly, and providing a high-quality user experience. As a component that frequently interacts with users, the user experience of the touchpad is of particular concern to users. In order to meet the growing user needs, full-area touch panels that can be used with full pressure are gradually emerging.

[0003] For example, the Chinese utility model patent with authorization announcement number CN215264735U specifically discloses a self-balancing full-area touchpad. When a user presses any position on the touchpad, the pressing force is transmitted to the entire touchpad through the balancing component, causing the entire touchpad to move downward. It has a good feel and high sensitivity, which improves the user experience.

[0004] The applicant found that the above-mentioned and similar full-area touch panels mainly rely on balancing parts and bending plates to achieve full-area operation. The above combination requires more parts, which increases the overall assembly process and manufacturing costs, and makes the touchpad module thicker, with a thickness of about 4 mm. This does not conform to the current development trend of ultra-thin and light laptops, and is unable to meet the users' growing usage needs. Utility Model Content

[0009] In a preferred embodiment, the inner bracket protrudes downward along the X-axis direction to form a second limiting protrusion, and the outer bracket is provided with a second limiting bend corresponding to the second limiting protrusion for limiting the X-axis displacement of the inner bracket relative to the outer bracket.

[0010] In a preferred embodiment, the elastic arm is in an "S" shape, and the boss is integrally arranged at the center of the elastic arm.

Compared with the traditional full-area touch panel module, the overall assembly process and manufacturing cost can be reduced, and the thickness of the touch panel module can be made thinner after reducing the parts, with a thickness of only about 3.65 mm, which is in line with the current development trend of ultra-thin and light laptops.

[0026] Among them, the touch switch 201 is a pot piece.

[0027] Furthermore, it also includes balance bars 5, which are two and are respectively arranged on both sides of the inner bracket 4; balance bars 5, which are two and are respectively arranged on both sides of the inner bracket 4, and multiple slots 45 are provided on both sides of the inner bracket 4 along the X-axis direction (wherein the X-axis direction is the length direction of the touch panel module), and the cross bar portion of the balance bar 5 can be pivotally buckled in the slot 45, and the four corners of the outer bracket 6 are integrally provided with hooks 64, and the hooks 64 have limiting holes, and the hooks of the balance bar 5 can be pivotally connected to the limiting holes. Balance bars 5 are designed on both sides of the touch panel module, and the cooperation of the slots 45 and the hooks 64 can assist in limiting the position of the balance bar 5 while also satisfying the relative rotation of the balance bar 5. Through the balance bar 5, when pressing any position of the touch panel, it can ensure that the touch switch 201 is subjected to uniform force, thereby making the pressing feel more consistent and improving the user's feel when using it.

[0028] Furthermore, the inner bracket 4 protrudes downward on both sides along the Y-axis direction (wherein the Y-axis direction is the width direction of the touchpad module) to form a limiting boss 41, and the outer bracket 6 is provided with a first limiting bend 61 corresponding to the limiting boss 41 for locking, which is used to limit the Y-axis displacement of the inner bracket 4 relative to the outer bracket 6. Through the cooperation of the limiting boss 41 and the first limiting bend 61, the touchpad module can be limited to shake along the Y-axis direction, which is more stable when pressed.

[0029] Furthermore, the inner bracket 4 protrudes downward along the X-axis direction to form a second limiting boss 42, and the outer bracket 6 is provided with a second limiting bend 62 corresponding to the second limiting boss 42 for limiting the X-axis displacement of the inner bracket 4 relative to the outer bracket 6. Through the cooperation of the second limiting boss 42 and the second limiting boss 42, the touchpad module can be limited to shake along the X-axis direction, which is more stable when pressed.

[0030] Furthermore, the elastic arm 44 is in an "S" shape, and the boss 441 is integrally arranged at the center of the elastic arm 44. The elastic arm 44 can form a certain suspended height between the PCBA mainboard and the bracket, thereby creating a pressing movement travel space for the touch panel module.

[0031] Furthermore, it also includes a glass plate 1, which is connected to the front side of the PCBA mainboard 2, and also includes a double-sided tape 3. The glass plate 1 and the PCBA mainboard 2 as well as the PCBA mainboard 2 and the inner bracket 4 are bonded together by the double-sided tape 3. After bonding, pressure is maintained by a pressure maintaining device. The pressure maintaining parameters are: air pressure 0.6MPa, and pressure maintaining time 6 seconds, so as to ensure the strength of the overall bonding.

[0032] The outer bracket 7 and the balancing rod 5 are preferably made of aluminum alloy, and the inner bracket 4 is preferably made of plastic, but this is not limited here.

[0033] Furthermore, the outer bracket 6 is also provided with a plurality of screw holes 65 in the circumferential direction, and the module is locked to the laptop computer (and secured by screws) through the plurality of fixing screw holes 65 on the outer bracket 6 , wherein the number of screw holes 65 is preferably 4, but not limited thereto.

[0034] To sum up, in the process of pressing the touch panel, the four locking structures between the inner bracket and the outer bracket are pressed together, so that the hook 63 of the outer bracket 6, the touch switch 201 and the force point of pressing the touch panel form a straight line, and the touch switch 201 is triggered according to the lever principle. Without adding additional accessories, full-area pressing can be achieved, which can reduce the overall assembly process and manufacturing costs. In addition, the thickness of the touch panel module can be made thinner after reducing the parts. At the same time, balance bars are designed on both sides of the touch panel module. The balance bar can ensure that the touch switch is evenly stressed when pressing any position of the touch panel, so that the pressing feel is more consistent, which can improve the user's feel when using it.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
