[0070] The elastic touchpad device and the electronic equipment with it of the utility model embodiment are described in detail below with reference to the drawings.

[0071] Referring to FIGS. 1-8, the elastic touchpad device according to the embodiments of the present application is suitable to be installed on a device shell 50, which is generally a shell of an electronic device, including but not limited to a notebook computer, a keyboard device, a calculator device, etc. The elastic touchpad device comprises a floating frame 10, an elastic support 20, a supporting member 40 and a touchpad assembly 30.

[0072] Specifically, the bottom of the floating frame 10 is provided with a plurality of positioning grooves H101, which can adopt various shapes such as rectangle, circle, etc. In specific application, the floating frame 10 is installed on the device shell 50 and can float up and down relative to the device shell 50. The floating frame 10 can adopt a metal material or a plastic material with high structural strength, such as stainless steel, glass fiber plate, etc.

[0073] The touchpad assembly 30 is located above the floating frame 10 and fixed with the floating frame 10. When the touchpad assembly 30 is pressed, the touchpad assembly 30 and the floating frame 10 can move downward synchronously. The elastic support 20 can adopt a metal material with elasticity, such as stainless steel, etc., to ensure that the elastic support 20 can provide reliable elastic support. The elastic support 20 comprises a center part 201 and a plurality of elastic arms 202, the plurality of elastic arms 202 are arranged along the circumference of the center part 201, the center part 201 can be formed in various shapes, such as rectangle, circle, polygon, etc., and in order to make the thickness of the touchpad device thinner, the center part 201 can be configured as a sheet structure, etc. The plurality of elastic arms 202 correspond to the plurality of positioning grooves H101 one by one, one end of each elastic arm 202 is fixedly connected with the center part 201, for example, one end of the elastic arm 202 can be integrally formed with the center part 201, or can be fixed by welding, or can be connected by screw connection, hanging, etc. The other end of each elastic arm 202 has a positioning part 2021, the shape of the positioning part 2021 is matched with the positioning groove H101, and the size of the positioning part 2021 is smaller than the size of the positioning groove H101, so that the positioning part 2021 has a movement allowance in the positioning groove H101.

[0074] The supporting member 40 is suitable to be fixed on the device shell 50, and the supporting member 40 is located below the elastic support 20 and abuts against the center part 201, so as to provide elastic support for the floating frame 10 by the supporting member 40 and the elastic support 20.

[0075] The support 40 can be made of metal or plastic material with certain elasticity. In specific applications, the support 40 can be fixed to the device shell 50, and since the support 40 is located below the elastic support 20 and abuts against the center portion 201. When the touchpad assembly 30 is pressed, the floating frame 10 and the touchpad assembly 30 move downward synchronously, and since the center portion 201 abuts against the support 40, the elastic support 20 deforms elastically with the downward movement of the floating frame 10, at this time, the center portion 201 exerts a certain pressure on the support 40, and the support 40 exerts an upward supporting action on the center portion 201. When the touchpad assembly 30 is released, the elastic support 20 restores the deformation, and the floating frame 10 and the touchpad assembly 30 quickly float up to reset. During the entire pressing operation, the support of the support 40 can make the touchpad assembly 30 have a thicker pressing feeling and a more reliable rebound effect when pressed. In addition, the durability of the touchpad device is also ensured.

[0076] It should be noted that in the above structure, on the one hand, the plurality of elastic arms 202 are arranged 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 dispersed and balanced elastic support to the touchpad 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 positional relationship between the two is stable and reliable, thereby ensuring that the elastic support 20 can reliably and stably deform elastically when the floating frame 10 moves downward, 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 movement, so that the elastic support 20 has a certain self-adaptive deformation capability. This self-adaptive deformation makes the torque of each elastic arm 202 relatively uniform.

[0077] 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 touchpad assembly 30 and the deformation amount of the elastic support 20. Generally, the pressing stroke of the touchpad assembly 30 is small, so the size of the positioning portion 2021 is slightly smaller than the size of the positioning groove H101. As shown in FIG. 9, 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 can be the distance between the edge of the positioning portion 2021 and the side wall of the positioning groove H101.

[0078] The bottom center of the touchpad assembly 30 is provided with a button 304, which is close to the center part 201 or the support 40, so that when the touchpad assembly 30 is pressed, the center part 201 or the support 40 triggers the button 304. By triggering the button 304 when the touchpad assembly 30 is pressed, a mouse-like click operation is realized.

[0079] It should be understood that the above-mentioned "close" can be a contact state, or a close state formed with a certain distance. Preferably, the button 304 is in contact with the center part 201 or the support 40, thereby ensuring that when the touchpad assembly 30 is pressed, the pressing stroke is short, and the button 304 is triggered reliably.

[0080] According to the elastic touchpad device provided in the embodiments of the present application, the hanging column 101 is arranged at the bottom of the floating frame 10, and the positioning part 2021 is arranged at the other end of the elastic arm 202 and positioned and matched with the positioning groove H101, and the size of the positioning part 2021 is smaller than the size of the positioning groove H101. With this structure design, when the touchpad assembly 30 is pressed, the elastic support 20 is compressed, and there is a movement allowance between the positioning part 2021 and the positioning groove H101, each elastic arm 202 can be deformed adaptively, so that the torque of each elastic arm 202 is uniform, and the elastic support effect on the touchpad assembly 30 is also relatively uniform. In use, the pressing feeling is better, the pressing force at different positions is relatively uniform, and the use experience can be significantly improved. In addition, this positioning method using the positioning groove H101 and the positioning part 2021 avoids the problem that the adhesive fixing method is easy to fail under stress, thereby ensuring the reliability of the elastic touchpad device during long-term use and a longer service life.

[0081] Exemplarily, the touchpad assembly 30 generally includes a touch circuit board 302 and a TP plate 301 (i.e., a "touchpad"), and the TP plate 301 is adhesively fixed on the upper surface of the touch circuit board 302. The button 304 is arranged at the center position of the bottom surface of the touch circuit board 302. The floating frame 10 is adhesively fixed on the lower surface of the touch circuit board 302 by the adhesive 303, and the overall structure is thin and light, and simple and reliable.

[0082] Referring to FIGS. 6-7, in some embodiments of the present application, the center part 201 and the bottom surface of the floating frame 10 have a predetermined spacing H. The predetermined spacing H can be designed according to the pressing stroke of the touchpad assembly 30. For example, if the pressing stroke of the touchpad assembly 30 is relatively short, the predetermined spacing H between the center part 201 and the floating frame 10 can be relatively small. In this way, the requirement of the pressing stroke can be met, and it is also beneficial to realize a more lightweight design.

[0083] Since the center portion 201 is in abutment with the support member 40, the elastic support 20 is between the floating frame 10 and the support member 40, and the elastic support 20 has a certain height dimension in the up-down direction. When the floating frame 10 is moved downward with the touchpad assembly 30 being pressed, and the support member 40 is fixed on the device shell 50, therefore, the elastic support 20 can be reliably and stably compressed under the pressure of the floating frame 10, and further, elastic deformation is generated.

[0084] In the embodiment, the center portion 201 has a predetermined spacing between the bottom surface of the floating frame 10, so that the elastic support 20 is more easily deformed by compression, and the compression deformation mode in combination with the structure design of the plurality of elastic arms 202 arranged in a circumferential direction can improve the reliability and uniformity of the elastic support during pressing operation.

[0085] Of course, it can be understood that in other embodiments, the center portion 201 can also be in the same plane as the floating frame 10, or even the center portion 201 is in a predetermined position above the floating frame 10, in which case, a support portion protruding upward can be provided on the support member 40, and the support portion is in abutment with the center portion 201, so that when the floating frame 10 is floated downward, the elastic support 20 can also be elastically deformed under the support of the support portion on the center portion 201. Therefore, as long as the elastic support 20 can be elastically deformed when the floating frame 10 is floated downward, the purpose of the application can be achieved, and these embodiments also belong to the protection scope of the application.

[0086] Referring to FIGS. 3-4 and 6-8, in an embodiment of the present application, the center portion 201 is plate-shaped, and the elastic arms 202 are strip-shaped and extend outwardly of the center portion 201 and gradually offset upwardly.

[0087] In the embodiment, the center portion 201 is plate-shaped, which can achieve a lighter and thinner design. The elastic arms 202 extend outwardly and offset upwardly, so that the elastic support 20 has a certain height dimension in the up-down direction, and the elastic arms 202 and the center portion 201 form an inverted frustoconical structure, which ensures that the elastic support 20 forms a stable compression structure and has a suitable compression amount. In this way, when the floating frame 10 is floated downward, the elastic support 20 can be stably compressed to generate deformation, further improving the reliability and uniformity of pressing and the use feel.

[0088] Referring to FIGS. 2-3 and 5, in one embodiment of the present application, the bottom of the floating frame 10 is provided with a plurality of hanging columns 101, the plurality of hanging columns 101 correspond to the plurality of positioning grooves H101 one by one, each of the hanging columns 101 is arranged in the corresponding positioning groove H101; each of the positioning portions 2021 has a sleeve joint hole H201 which is sleeved on the hanging column 101, and the diameter of the sleeve joint hole H201 is greater than the diameter of the hanging column 101. The hanging column 101 can adopt a protruding columnar structure such as a cylinder or a prism.

[0089] In assembly, the elastic support 20 is aligned with the floating frame 10 up and down, the positioning portions 2021 of the plurality of elastic arms 202 are respectively arranged in the corresponding positioning grooves H101, and each of the sleeve joint holes H201 is sleeved on the corresponding hanging column 101.

[0090] In the embodiment, on the one hand, the sleeve joint cooperation of the sleeve joint hole H201 and the hanging column 101 can further position and fix the elastic arm 202, ensure the combination relationship between the elastic support 20 and the floating frame 10 to be more stable and reliable, and further ensure the stability of the entire elastic support 20 structure and the reliability in compression. On the other hand, after the sleeve joint hole H201 on the positioning portion 2021 is sleeved on the hanging column 101 in the positioning groove H101, the positioning portion 2021 is located in the positioning groove H101 and does not protrude from the bottom surface of the floating frame 10, so that the structure is compact, the elastic support 20 can be more close to the touch panel assembly 30 upward, and the requirement of shorter pressing stroke is met. On the other hand, since the diameter of the sleeve joint hole H201 is greater than the diameter of the hanging column 101, the elastic arm 202 still has a certain activity allowance after positioning, and the self-adaptive elastic deformation ability of the elastic support 20 is ensured.

[0091] Referring to FIGS. 3-5, in some embodiments of the present application, the floating frame 10 is formed as a frame piece, the middle of the frame piece is formed with a hollow area P10, a plurality of positioning grooves H101 are arranged around the hollow area P10, and the center portion 201 is located in the center of the hollow area P10.

[0092] That is, the floating frame 10 is designed as a hollow frame structure in the middle, and a plurality of positioning grooves H101 are distributed around the frame piece and arranged around the hollow area P10. The design not only reduces the weight of the floating frame 10 and realizes thinning, but also provides space for the arrangement of the center portion 201, and facilitates the contact of the keys 304 on the touch panel assembly 30 with the center portion 201 or the support 40.

[0093] It can be understood that the frame member can be an integral frame member, and can also be a split frame member composed of two symmetrical U-shaped frames, which can be connected or not connected. When the frame member is fixed to the touchpad assembly 30 and is floatingly installed on the device in specific applications, it can be achieved that the frame member is synchronously floated up and down with the touchpad assembly 30.

[0094] Preferably, the frame member is a rectangular frame, and the four positioning grooves H101 are respectively arranged at four corners of the rectangular frame. That is, four positioning grooves H101 are arranged at 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 elastic support 20 is uniformly stressed and has better stability and higher bearing capacity.

[0095] In other embodiments, the frame member can adopt other shapes, such as a circular shape, a polygonal shape, etc., and can be designed according to the shape and stress balance of the touchpad assembly 30. For example, when the touchpad assembly 30 is rectangular, the frame member can also be rectangular. Of course, the shapes of the two are not necessarily the same, for example, the frame member can also adopt a circular design.

[0096] Referring to FIGS. 2 to 4, in an embodiment of the present application, the supporting member 40 is formed as a strip-shaped plate member, which extends along the left-right direction and is arranged centrally in the front-rear direction in the middle of the hollowed-out area P10, and both ends of the strip-shaped plate member are adapted to be fixed to the device shell 50.

[0097] In the present embodiment, the supporting member 40 adopts a strip-shaped plate member, which is arranged centrally in the front-rear direction in the hollowed-out area P10. This central arrangement not only makes the structure of the central part 201 of the elastic support 20 coincide with the structure of the strip-shaped plate member, but also makes the stress reaction of the strip-shaped plate member caused by the force applied by the central part 201 more direct, concentrated and stable during the pressing process, which helps to ensure that the pressing process is more uniform and the hand feeling is consistent. The design of the strip-shaped plate member makes the overall structure of the device thinner, and also makes the supporting member 40 more easily deformed, thereby providing reliable support.

[0098] Preferably, the strip-shaped plate member has a middle section 401 which protrudes upward and abuts against the central part 201. During the pressing process, the force applied downward by the central part 201 can be efficiently and directly transmitted to the protruding middle section 401, and at the same time, the protruding middle section 401 also limits the travel of the central part 201 from moving downward too much, thereby playing a good supporting and travel limiting role.

[0099] Referring to FIG. 3 and FIG. 4, in some embodiments of the present application, the center part 201 is provided with a through hole H202, the supporting part 40 is provided with an adjusting part 41, the adjusting part 41 is formed to be movable and adjustable in the position along the up-down direction, and the adjusting part 41 passes through the through hole H202 and abuts against the key 304.
