[0069] The elastic touch panel device and the electronic device having the same according to the embodiment of the utility model are described in detail below with reference to the accompanying drawings.

[0070] Reference Figures 1 to 8 As shown, the elastic touch panel device provided according to the embodiment of the utility model is suitable for being installed in a device housing 50, which is generally a housing of an electronic device, including but not limited to a laptop computer, a keyboard device, a calculator device, etc. The elastic touch panel device includes a floating frame 10, an elastic bracket 20, a supporting member 40 and a touch panel assembly 30.

[0071] Specifically, a plurality of positioning grooves H101 are provided at the bottom of the floating frame 10, and the positioning grooves H101 can be in various shapes such as rectangular, circular, etc. In a specific application, the floating frame 10 is mounted to the device housing 50 and can float up and down relative to the device housing 50. The floating frame 10 can be made of metal material or plastic material with high structural strength, such as stainless steel, fiberglass board, etc.

[0072] The touch panel assembly 30 is located above the floating frame 10 and is fixed to the floating frame 10. When the touch panel assembly 30 is pressed, the touch panel assembly 30 and the floating frame 10 can move downward synchronously. The elastic bracket 20 can be made of an elastic metal material, such as stainless steel, to ensure that the elastic bracket 20 can provide reliable elastic support. The elastic bracket 20 includes a central portion 201 and a plurality of elastic arms 202, and the plurality of elastic arms 202 are arranged at intervals along the circumference of the central portion 201. The central portion 201 can be formed into various shapes, such as a rectangle, a circle, a polygon, etc., and in order to make the thickness of the touch panel device thinner, the central portion 201 can be constructed into a sheet-like structure. And the plurality of elastic arms 202 correspond to the plurality of positioning grooves H101 one by one, and one end of each elastic arm 202 is fixedly connected to the central portion 201. For example, one end of the elastic arm 202 and the central portion 201 can be integrally formed, or welded and fixed by welding, or connected by screw connection, hanging, etc. The other end of each elastic arm 202 has a positioning portion 2021, the shape of the positioning portion 2021 is adapted to the positioning slot H101, and the size of the positioning portion 2021 is smaller than the size of the positioning slot H101, so that the positioning portion 2021 has a movable margin in the positioning slot H101.

[0073] The supporting member 40 is suitable for being fixed to the device housing 50 . The supporting member 40 is located below the elastic bracket 20 and abuts against the central portion 201 , so as to provide elastic support for the floating frame 10 through the supporting member 40 and the elastic bracket 20 .

[0074] The supporting member 40 can be made of metal or plastic with a certain elasticity. In a specific application, the supporting member 40 can be fixed to the device shell 50, because the supporting member 40 is located below the elastic bracket 20 and abuts against the central part 201. When the touch pad assembly 30 is pressed, the floating frame 10 and the touch pad assembly 30 move downward synchronously. Since the central part 201 abuts against the supporting member 40, the elastic bracket 20 elastically deforms as the floating frame 10 moves downward. At this time, the central part 201 exerts a certain pressure on the supporting member 40, and the supporting member 40 exerts an upward support on the central part 201. When the touch pad assembly 30 is released, the elastic bracket 20 recovers the deformation, so that the floating frame 10 and the touch pad assembly 30 quickly float up and reset. During the entire pressing operation, under the support of the supporting member 40, the touch pad assembly 30 can have a heavier pressing feel and a more reliable rebound effect when pressed. Furthermore, the durability of the touchpad device is also ensured.

[0075] It should be noted that in the above structure, on the one hand, the multiple elastic arms 202 are arranged at intervals along the circumference of the center portion 201, which can ensure that the center portion 201 remains stable and balanced, thereby ensuring that the elastic support 20 provides a dispersed and balanced elastic support for the touch panel assembly 30. On the other hand, the elastic arm 202 is positioned and matched with the positioning groove H101 on the floating frame 10 through the positioning portion 2021, so that the elastic support 20 is positioned on the floating frame 10, and the relative position relationship between the two is stable and reliable, thereby ensuring that when the floating frame 10 moves downward, the elastic support 20 can reliably and stably produce elastic deformation, that is, the stability of the entire elastic support 20 structure and the reliability during elastic deformation are improved. On the other hand, since the size of the positioning groove H101 is slightly larger than the size of the positioning portion 2021, the elastic arm 202 has a certain amount of activity margin, so the elastic support 20 can have a certain adaptive deformation ability, and this adaptive deformation makes the torque of each elastic arm 202 relatively uniform.

[0076] The difference between the size of the positioning portion 2021 and the size of the positioning groove H101 can be determined according to the pressing stroke of the touch panel assembly 30 and the deformation of the elastic bracket 20. Generally, the pressing stroke of the touch panel assembly 30 is small, so the size of the positioning portion 2021 can be slightly smaller than the size of the positioning groove H101. Fig. 9 As shown, for example, the difference ΔD between the size of the positioning portion 2021 and the size of the positioning groove H101 is between 0.05 and 0.2 mm. The difference ΔD may be the distance between the edge of the positioning portion 2021 and the side wall of the positioning groove H101.

[0077] A button 304 is provided at the bottom center of the touchpad assembly 30, and the button 304 is close to the central portion 201 or the supporting member 40, so that when the touchpad assembly 30 is pressed, the central portion 201 or the supporting member 40 triggers the button 304. By triggering the button 304 when the touchpad assembly 30 is pressed, a click operation similar to a mouse is achieved.

[0078] It should be understood that the above-mentioned "close to each other" can be a contact state or a close state formed by a certain distance. Preferably, the button 304 is in contact with the central part 201 or the supporting member 40, thereby ensuring that when the touch panel assembly 30 is pressed, the pressing stroke is short and the button 304 is reliably triggered.

[0079] According to the elastic touch panel device provided by the embodiment of the utility model, a hanging column 101 is provided at the bottom of the floating frame 10, and a positioning portion 2021 is provided at the other end of the elastic arm 202 to be positioned and matched with the positioning groove H101, and the size of the positioning portion 2021 is smaller than the size of the positioning groove H101. With this structural design, when the touch panel assembly 30 is pressed, the elastic bracket 20 is compressed, and there is a movable margin between the positioning portion 2021 and the positioning groove H101, and each elastic arm 202 can deform adaptively, so that the torque of each elastic arm 202 is uniform, and then the elastic support effect generated on the touch panel assembly 30 is also relatively uniform. In use, the pressing feel is better, and the pressing force at different positions is relatively uniform, which can significantly improve the user experience. In addition, this positioning method using the positioning groove H101 and the positioning portion 2021 avoids the problem that the adhesive fixing method is prone to failure due to force, and ensures the reliability of the elastic touch panel device for long-term use and a longer service life.

[0080] For example, the touch panel assembly 30 generally includes a touch circuit board 302 and a TP board 301 (i.e., a "touch panel"), wherein the TP board 301 is bonded and fixed to the upper surface of the touch circuit board 302. The button 304 is disposed at the center of the bottom surface of the touch circuit board 302. The floating frame 10 is bonded and fixed to the lower surface of the touch circuit board 302 by means of adhesive 303, and the overall structure is thin, simple, and reliable.

[0081] Reference Figure 6 to Figure 7 As shown, in some embodiments of the present invention, there is a predetermined distance H between the central portion 201 and the bottom surface of the floating frame 10. The predetermined distance H can be designed according to the pressing stroke of the touch panel assembly 30. For example, if the pressing stroke of the touch panel assembly 30 is relatively short, the predetermined distance H between the central portion 201 and the floating frame 10 can be relatively small, so that the pressing stroke requirement can be met and a thinner design can be achieved.

[0082] Since the center portion 201 is in contact with the supporting member 40, the elastic bracket 20 is located between the floating bracket 10 and the supporting member 40, and the elastic bracket 20 has a certain height dimension in the vertical direction. When the floating bracket 10 moves downward as the touch panel assembly 30 is pressed, and the supporting member 40 is fixed on the device housing 50, the elastic bracket 20 can be reliably and stably compressed under the pressure applied by the floating bracket 10, thereby generating elastic deformation.

[0083] In this embodiment, a design with a predetermined distance between the central portion 201 and the bottom surface of the floating frame 10 is adopted, so that the elastic bracket 20 can be more easily deformed by compression. In addition, the combination of this compression deformation method and the structural design of multiple elastic arms 202 arranged at circumferential intervals can improve the reliability and balance of the elastic support during the pressing operation.

[0084] Of course, it is understandable that in other embodiments, the central portion 201 may also be in the same plane as the floating frame 10, or even in a predetermined position above the floating frame 10. In this case, a support portion protruding upward may be provided on the support member 40, and the support portion is used to abut against the central portion 201. Then, when the floating frame 10 floats downward, the elastic bracket 20 can also produce elastic deformation under the support of the support portion to the central portion 201. Therefore, as long as it can be ensured that the elastic bracket 20 can produce elastic deformation when the floating frame 10 floats downward, the invention purpose of the present application can be achieved, and these embodiments also belong to the protection scope of the present application.

[0085] Reference Figure 3 to Figure 4 and Figures 6 to 8 As shown, in one embodiment of the present invention, the central portion 201 is plate-shaped, and the elastic arms 202 are strip-shaped and extend toward the outside of the central portion 201 and gradually deviate upward.

[0086] In this embodiment, the central part 201 is plate-shaped, which can achieve a lighter and thinner design. The elastic arms 202 extend outward and deflect upward, so that the elastic bracket 20 forms a certain height dimension in the vertical direction, and each elastic arm 202 and the central part 201 are enclosed to form an inverted frustum-shaped structure, under which the elastic bracket 20 forms a stable compression structure and has a suitable compression amount. In this way, when the floating frame 10 floats downward, the elastic bracket 20 can be stably compressed to produce deformation, further improving the reliability and balance of pressing and the feel of use.

[0087] Reference Figures 2 to 3 and Figure 5 As shown, in one embodiment of the present invention, a plurality of hanging posts 101 are provided at the bottom of the floating frame 10, and the plurality of hanging posts 101 correspond to the plurality of positioning slots H101 one by one, and each hanging post 101 is provided in the corresponding positioning slot H101; each positioning portion 2021 has a sleeve hole H201 sleeved on the hanging post 101, and the diameter of the sleeve hole H201 is larger than the diameter of the hanging post 101. The hanging post 101 can be a protruding columnar structure such as a cylinder or a prism.

[0088] During assembly, the elastic bracket 20 is aligned with the floating bracket 10 up and down, so that the positioning parts 2021 of the plurality of elastic arms 202 enter the corresponding positioning grooves H101 respectively, and each sleeve hole H201 is respectively inserted into the corresponding hanging column 101.

[0089] In this embodiment, on the one hand, by using the sleeve hole H201 and the hanging column 101, the elastic arm 202 can be further positioned and fixed, ensuring that the combination relationship between the elastic bracket 20 and the floating bracket 10 is more stable and reliable, thereby ensuring the stability of the entire elastic bracket 20 structure and the reliability during compression. On the other hand, after the sleeve hole H201 on the positioning part 2021 is sleeved on the hanging column 101 in the positioning groove H101, the positioning part 2021 is located in the positioning groove H101 and does not protrude from the bottom surface of the floating bracket 10. Therefore, not only can the structure be made compact, but also the elastic bracket 20 can be closer to the touch panel assembly 30 upwards, meeting the requirement of a shorter pressing stroke. On the other hand, since the diameter of the sleeve hole H201 is larger than the diameter of the hanging column 101, the elastic arm 202 can still retain a certain amount of activity after positioning, ensuring the adaptive elastic deformation ability of the elastic bracket 20.

[0090] Reference Figures 3 to 5 As shown, in some embodiments of the present invention, the floating frame 10 is formed as a frame member, a hollow area P10 is formed in the middle of the frame member, a plurality of positioning grooves H101 are arranged at intervals around the hollow area P10, and the central portion 201 is located in the center of the hollow area P10.

[0091] That is, the floating frame 10 is designed as a hollow frame structure, and a plurality of positioning grooves H101 are distributed around the frame member and arranged at intervals around the hollow area P10. This design not only reduces the weight of the floating frame 10 and achieves lightness and thinness, but also provides space for the arrangement of the central part 201, and facilitates the contact between the key 304 on the touch panel assembly 30 and the central part 201 or the supporting member 40.

[0092] It is understandable that the frame member can be an integrated frame member or a split frame member composed of two symmetrical U-shaped frames, and the two U-shaped frames can be connected or not. When the frame member is fixed to the touch panel assembly 30 and is floatingly mounted on the device in a specific application, it can float up and down synchronously with the touch panel assembly 30.

[0093] Preferably, the frame member is a rectangular frame, and the number of the positioning grooves H101 is four, and the four positioning grooves H101 are respectively arranged at the four corners of the rectangular frame. That is, four positioning grooves H101 are distributed at the four corners of the rectangular frame member. The layout of the four positioning grooves H101 is simple and highly symmetrical, which can ensure that the entire elastic bracket 20 is evenly stressed, has better stability, and has a higher load-bearing capacity.

[0094] In other embodiments, the frame member may adopt other shapes, such as circular, polygonal, etc., and may be specifically designed according to the shape of the touchpad assembly 30 and the force balance. For example, the touchpad assembly 30 is rectangular and the frame member may also be rectangular. Of course, the shapes of the two are not required to be the same. For example, the frame member may also be circular.

[0095] Reference Figures 2 to 4 As shown, in one embodiment of the utility model, the supporting member 40 is formed as a strip plate, which extends in the left-right direction, and is centrally arranged in the middle of the hollow area P10 in the front-back direction, and both ends of the strip plate are suitable for being fixed to the device shell 50.

[0096] In this embodiment, the support member 40 is a strip plate, which is arranged in the center of the hollow area P10 in the front-to-back direction. This central arrangement not only makes it highly overlapped with the central part 201 of the elastic bracket 20, but also makes the force response of the central part 201 to the strip plate more direct, concentrated and stable during the pressing process, which also helps to ensure that the pressing process is more uniform and the hand feel is consistent. The design of the strip plate can make the overall structure of the device thinner and lighter, and also makes the support member 40 easier to deform to a certain extent, thereby providing a reliable support effect.

[0097] Preferably, the strip plate has a middle section 401, which protrudes upward and abuts against the central portion 201. During the pressing process, the force applied downward by the central portion 201 can be efficiently and directly transmitted to the protruding middle section 401. At the same time, the protruding middle section 401 also limits the excessive downward movement of the central portion 201, playing a good supporting and travel limiting role.

When the position of the adjusting member 41 is raised, the stroke of the button 304 will be reduced accordingly, and vice versa. This design can effectively adjust the pressing stroke, and then adjust the pressing feel, so as to meet personalized needs.

[0100] Exemplarily, the adjusting member 41 is a threaded member, and a threaded hole H40 is provided on the supporting member 40. The threaded member cooperates with the threaded hole H40. When the threaded member is rotated, the distance between the top of the threaded member and the button 304 can be changed, thereby realizing the adjustment of the pressing stroke. The threaded member has a simple structure, convenient adjustment operation and high adjustment accuracy.
