Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The present application relates to touch pads (or also referred to as touchpads). Specifically, the touch pad may provide an interactive touch and press interface with a user's finger. In the pressing interface, the touch pad may sense a pressing operation of a user to perform corresponding pressing feedback or instruct an electronic device where the touch pad is located to perform a corresponding function, and the pressing interface may serve as a "key" function. In a touch interface, a touch pad may be used to sense the position and movement of a user's finger to perform corresponding touch feedback or instruct the electronic device in which it is located to perform corresponding functions, and the touch interface may function as a "mouse".

The touch pad may be applied to any man-machine interaction device, such as a notebook computer, a tablet computer, a mobile phone, an intelligent wearable device, an intelligent door lock, an automatic teller machine (Automated Teller Machine, ATM), and the like, to which embodiments of the present disclosure are not limited.

For the pressing interface of the touch pad, in the prior art, a special mechanical structural component, such as a swinging rod and other structural components, are required to be used for realizing pressing detection, the touch pad cannot realize global pressing, and the consistency of the pressing force of clicking on the touch pad by a user is poor, so that the user experience is poor. In view of this, the present application provides a new touch pad, which can realize the global pressing of the touch pad, and can realize the balanced force feedback at any position of the touch pad.

Fig. 2 and 3 show a schematic cross-sectional view and a schematic exploded view of a touch pad 10 according to an embodiment of the present application.

As shown in fig. 2 and 3, the touch pad 10 includes: the touch assembly 100 and the support assembly 200.

Specifically, the touch assembly 100 is configured to receive a user's press, and a travel switch 101 is disposed on a lower surface of the touch assembly 100.

The support assembly 200 includes: the main support 210, the first elastic member 220, the second elastic member 230, and the fixed platform 240.

The main support 210 is disposed at an edge of the lower surface of the touch assembly 100, and the main support 210 is frame-shaped and has a first edge 211 and a second edge 212 opposite to each other. The first elastic member 220 and the second elastic member 230 are disposed below the main support 210 and symmetrically connected to the main support 210 along a plane of the main support 210. The fixed platform 240 is disposed below the first elastic member 220 and the second elastic member 230, the first elastic member 220 is connected between the first edge 211 of the main support member 210 and the fixed platform 240, the second elastic member 230 is connected between the second edge 212 of the main support member 210 and the fixed platform 240, and the surface of the fixed platform 240 facing the touch assembly 100 is provided with a contact 241.

When any position of the touch assembly 100 is pressed, the touch assembly 100 is forced to move downward, the first elastic member 220 and the second elastic member 230 are elastically deformed, and the contact 241 on the fixed platform 240 contacts and triggers the travel switch 101 on the touch assembly 100.

Specifically, the touch assembly 100 may be a plate-like structure, so as to provide a pressing interface for a user. The touch assembly 100 may include: a circuit board 120. After the touch pad 10 of the touch assembly 100 is assembled in the electronic device, the circuit board 120 may be disposed on the lower surface of the cover 110, and the user presses the circuit board 120 by pressing the circuit board 110. Alternatively, in some embodiments, the touch assembly 100 may directly include: the cover plate 110 and the circuit board 120, the touch pad 10 where the touch assembly 100 is located can be directly assembled to the electronic device, and no additional cover plate is required. Alternatively, as shown in fig. 2 and 3, the cover plate 110 and the circuit board 120 may be connected to each other by a connection member, such as a glue layer 111.

The cover 110 is located on the outer surface of the entire touch pad 10 and is a generally planar sheet of rigid material with an upper surface configured to contact one or more user objects, e.g., fingers, styluses, when the touch pad 10 is operated. Thus, a user may provide input by clicking, sliding, or pressing or otherwise applying a force to the surface of the cover plate 110 using one or more of the user objects described above.

It should be noted that, for convenience of description, in this application, "upper" and "lower" refer to a direction toward a user and a direction away from the user, respectively, rather than an absolute "gravitational opposite direction" and "gravitational direction". Therefore, the upper surface of the cover plate 110 is the surface facing the user, whereas the lower surface of the cover plate 110 is the surface facing away from the user. Similar to the cover plate 110, hereinafter, the "up", "down" directions of the other components of the touch pad 10 may also be understood as directions toward the user and directions away from the user.

The cover plate 110 is made of a rigid material, and may specifically be a rigid object such as glass, a Polycarbonate (PC) sheet, a ceramic sheet, and a Mylar (Mylar) sheet. The top surface of the cover plate 110 may be smooth or roughened to provide a touch pad with an aesthetic design. The cover plate 110 may be generally rectangular in shape, and in some embodiments, the rectangular outer surface edges of the cover plate 110 may also be rounded.

The circuit board 120 may specifically be a printed circuit board (Printed Circuit Board, PCB) or a flexible circuit board with reinforcement (Flexible Printed Circuit, FPC). Printed circuit board assemblies (Printed Circuit Board Assembly, PCBA) may be formed by configuring touch sensors, travel switches 101, connectors, and other electronic components on circuit board 120 via surface mount technology (Surface Mounted Technology, SMT) patch mounting, or via Dual In-line Package (DIP). The PCBA can be used for realizing touch sensing and pressing detection functions of the touch pad. Alternatively, the PCBA may implement a communication function through a connector and a pen-powered keyboard or a holster keyboard. Optionally, the touch sensor in the PCBA is specifically a touch sensitive layer built into the circuit board 120.

The travel switch 101 may include an elastic structure protruding from the lower surface of the circuit board 120 and a conducting point disposed on the lower surface of the circuit board 120. In cooperation with the travel switch 101, a contact 241 is disposed on a surface of the fixed platform 240 facing the circuit board 120, and the contact 241 may be a protruding structure protruding toward the circuit board 120 in the fixed platform 240. In the case that the user does not press the cover plate 110, the elastic structure may be in contact with or separated from the contact 241, and at this time, the state of the elastic structure is its initial state or default state. In the case where the elastic structure and the contact 241 are separated from each other, the initial state of the elastic structure is an undeformed state. In the case where the elastic structure and the contact 241 are in contact with each other, the initial state of the elastic structure may be a micro-deformed state or an undeformed state.

Under the condition that the user presses the cover plate 110 with his/her finger, the elastic structure in the travel switch 101 can move along the pressing direction and contact with the contact 241 to deform the elastic structure, and the deformed elastic structure contacts with the conducting point of the circuit board 120 to conduct the travel switch 101. After the pressing force of the cover plate 110 is withdrawn by the user's finger, the deformed elastic structure can be restored to the original state, and the elastic structure is not in contact with the conductive point of the circuit board 120, so that the travel switch 101 is turned off. In the travel switch 101, the movement travel of the elastic structure in the pressing direction can be understood as the pressing travel of the travel switch 101. As a possible embodiment, the elastic structure in the travel switch 101 may be a dome sheet, and the travel switch may be understood as a dome key. Alternatively, in some alternative embodiments, the travel switch 101 may be a switch in addition to a dome key, and the specific implementation of the travel switch 101 is not limited in this embodiment.

Alternatively, as shown in fig. 2 and 3, the travel switch 101 may be fixed to a central region of the lower surface of the circuit board 120 by means of bonding or SMT. Alternatively, in other embodiments, the position of the travel switch 101 may be disposed at other positions on the lower surface of the circuit board 120 as desired.

In addition to the touch assembly 100, the touch pad 10 further includes a supporting assembly 200 for supporting the touch assembly 100.

Specifically, in the support assembly 200, the main support 210 may be a frame-type support that is disposed at an edge of the lower surface of the circuit board 120. Alternatively, the main support 210 may be connected to an edge of the lower surface of the circuit board 120 by a connection member (e.g., an adhesive layer 201).

The shape of the main support 210 may be adapted to the shape of the circuit board 120, for example, in the case where the circuit board 120 is a rectangular circuit board, the main support 210 may be a rectangular frame type. In addition, the main support member 210 needs to have a certain rigidity and strength, so as to ensure reliable support of the touch assembly 100 and improve the overall strength of the touch pad 10.

In addition, in the support assembly 200, the fixing platform 240 is a fixedly disposed component. The touch pad 10 can be mounted on an electronic device through the fixing platform 240, and the fixing platform 240 can be stably fixed in the electronic device. The fixed platform 240 also needs to have a certain rigidity and strength to ensure reliable support of the touch assembly 100 and improve the overall strength of the touch pad 10.

In the embodiment of the present application, the fixing platform 240 and the main support 210 may be connected to each other by the first elastic member 220 and the second elastic member 230. Specifically, the first elastic member 220 is connected between the first edge 211 of the main support 210 and the fixed platform 240, and the second elastic member 230 is connected between the second edge 212 of the main support 210 and the fixed platform 240. Under the condition that the user presses the touch assembly 100, the touch assembly 100 drives the main support 210 connected with the touch assembly to move in the pressing direction, the first elastic member 220 and the second elastic member 230 elastically deform under the action of the pressing force, and the travel switch 101 in the touch assembly 100 can contact the contact 241 on the fixed platform 240 to detect the pressing of the user. After the pressing force of the user is withdrawn, the first elastic member 220 and the second elastic member 230 can be restored, and the two elastic members, the main supporting member 210 and the fixing platform 240 can perform a good supporting function on the touch assembly 100.

In addition, the first elastic member 220 and the second elastic member 230 are symmetrically connected to the main support member 210 along the plane of the main support member 210, so that the first elastic member 220 and the second elastic member 230 have good symmetry in the touch pad 10, and can be respectively adapted to the pressing of the user in two symmetrical areas of the touch pad 10, so as to provide balanced force feedback to the user.

In summary, through the technical scheme of the embodiment of the application, the touch control assembly 100 and the touch control plate 10 formed by the support assemblies 200 with two elastic pieces not only can realize the whole-domain pressing, but also can provide balanced force feedback for users, and the touch control plate 10 has better overall performance, can be better suitable for various types of electronic equipment and can promote the use experience of the users.

In the embodiment shown in fig. 3, although the user presses the touch assembly 100 at any position, the pressing detection of the touch pad 10 can be realized, but when the user presses one end of the touch assembly 100, the other end of the touch assembly is tilted without constraint. At this time, the lifted-up touch assembly 100 affects the pressing stroke of the travel switch 101, thereby affecting the contact between the travel switch 101 and the contact 241, so as to affect the pressing detection performance of the touch pad 10.

In view of this, fig. 4 shows a schematic exploded view of another touch pad 10 according to the embodiment of the present application, based on the embodiment shown in fig. 3.

As shown in fig. 4, the support assembly 200 further includes: a first attachment member 250 attached to an upper surface of the first elastic member 220, and a second attachment member 260 attached to an upper surface of the second elastic member 230.

Fig. 5 shows a schematic enlarged view of the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260 of fig. 4. Fig. 6 shows a schematic top view of the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260 assembled. Fig. 6 (b) is an enlarged schematic view of a portion a in fig. 6 (a).

In contrast, the second sides of the first attachment member 250 and the first elastic member 220 are the sides remote from the first side 211 of the main support member 210.

Similarly, the first side of the second attachment member 260 and the second elastic member 230 is the side proximate to the second side 212 of the main support 210, wherein the first side of the second elastic member 220 is connected to the second side 212 of the main support 210. The second side of the second attachment member 260 and the second elastic member 230 are opposite sides away from the second edge 212 of the main support member 210. The first elastic member 220 is provided with an elastic connection member connected to the fixing platform 240 between the first side and the second side. The second elastic member 230 is provided with an elastic connection member connected to the fixing platform 240 between the first side and the second side. When a user presses the touch assembly 100, the elastic connection piece of the first elastic piece 220 connected to the fixed platform 240 between the first side and the second side can be used as a stress pivot of the first elastic piece 220, and the elastic connection piece of the second elastic piece 230 connected to the fixed platform 240 between the first side and the second side can be used as a stress pivot of the second elastic piece 230.

The second side of the first attachment 250 is provided with a first protrusion 2501 and the second side of the second attachment 260 is provided with a second protrusion 2601. In this case, the first protruding portion 2501 is provided to extend above the second side of the second elastic member 230, and the second protruding portion 2601 is also provided to extend above the second side of the first elastic member 220.

When the user presses the area of the touch assembly 100 near the first edge 211 of the main support 210, the first side of the first elastic member 220 moves downward, and correspondingly, the second side of the first elastic member 220 moves upward. At this time, the second side of the first elastic member 220 may act on the second protrusion 2601 of the second attachment member 260 above it, such that the second attachment member 260 moves the second side of the second elastic member 230 upward, and the second attachment member 260 and the first side of the second elastic member 230 move downward. In the case that the first side of the second elastic member 230 moves downward, the second edge 212 of the main support member 210 connected to the first side of the second elastic member 230 also moves the touch assembly 100 downward near the area of the second edge 212 of the main support member 210. Therefore, when the user presses the area of the touch assembly 100 near the first edge 211 of the main support 210, the area of the touch assembly 100 near the second edge 212 of the main support 210 will not tilt, thereby further improving the press detection performance of the touch pad 10.

Similarly, when the user presses the area of the touch assembly 100 near the second edge 212 of the main support 210, the first side of the second elastic member 230 moves downward, and correspondingly, the second side of the second elastic member 230 moves upward. At this time, the second side of the second elastic member 230 may act on the first protrusion 2501 of the first attachment member 250 located above it, such that the first attachment member 250 moves the second side of the first elastic member 220 upward, and the first attachment member 250 and the first side of the first elastic member 220 move downward. In the case that the first side of the first elastic member 220 moves downward, the first edge 211 of the main support member 210 connected to the first side of the first elastic member 220 also drives the touch assembly 100 to move downward near the area of the first edge 211 of the main support member 210. Therefore, when the user presses the area of the touch assembly 100 near the second edge 212 of the main support 210, the area of the touch assembly 100 near the first edge 211 of the main support 210 will not tilt, thereby further improving the pressing detection performance of the touch pad 10.

In summary, through the technical solution of the embodiment of the present application, when a user presses one end of the touch assembly 100, for example, when the user presses an end region of the touch assembly 100 near the first edge 211 of the main support 210 or presses an end region of the touch assembly 100 near the second edge 212 of the main support 210, the other end of the touch assembly 100 is not tilted under the combined action of the elastic member and the connecting member, so as to further improve the pressing detection performance of the touch pad 10.

In addition to the first and second attachment members 250 and 260 improving the pressing detection performance of the touch pad 10, the first attachment member 250 attached to the first elastic member 220 may reinforce the first elastic member 220, and the second attachment member 260 attached to the second elastic member 230 may reinforce the second elastic member 230.

Alternatively, as shown in fig. 3 to 6, the first elastic member 220 and the second elastic member 230 are both sheet-like members. Although the sheet-shaped first elastic member 220 and the second elastic member 230 are excellent in elasticity, they are weak in strength. In view of this, in the present embodiment, the first and second attachment members 250 and 260 are added to the support assembly 200, and the first and second attachment members 250 and 260 may also be sheet-shaped members, thus being easily attached to the first and second elastic members 220 and 230. In addition, the shape of the first attachment member 250 may be adapted to the first elastic member 220, and the shape of the second attachment member 260 may be adapted to the second elastic member 230. The first and second attachment members 250 and 260 may provide better support and reinforcement to the body regions of the first and second elastic members 220 and 230.

In combination with the first and second attachment members 250 and 260, the use reliability and the service life of the first and second elastic members 220 and 230 can be ensured while the elastic deformation of the first and second elastic members 220 and 230 is ensured.

Alternatively, as shown in fig. 3 to 6, the first elastic member 220 and the second elastic member 230 have the same shape. Correspondingly, the first attachment 250 and the second attachment 260 may be similar or identical in shape. The first and second attachment members 250 and 260 may be disposed on upper surfaces of the first and second elastic members 220 and 230. In this case, the first and second attachments 250 and 260 may be accommodated in the hollow region of the frame-type main support 210.

Alternatively, in order to secure the elastic properties of the first elastic member 220 and the second elastic member 230, the first elastic member 220 and the second elastic member 230 are thinner. To secure the reinforcement performance of the first and second attachment members 250 and 260, the thickness of the first and second attachment members 250 and 260 may be thicker. As an example, the thickness of the first and second attachment members 250 and 260 may be greater than the thickness of the first and second elastic members 220 and 230.

In some embodiments, the touch assembly 100 is a rectangular touch assembly, referring back to fig. 5, the first elastic member 220 has two first elastic arms 221 parallel to the long side direction of the rectangular touch assembly and a first middle portion 222 connecting the two first elastic arms 221, and the second elastic member 230 has two second elastic arms 231 parallel to the long side direction of the rectangular touch assembly and a second middle portion 232 connecting the two second elastic arms 231. In the direction parallel to the long side of the rectangular touch assembly, the two first elastic arms 221 and the two second elastic arms 231 correspond to each other with a gap.

Through the technical solution of this embodiment, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 231 of the second elastic member 230 are parallel to the long-side direction of the rectangular touch assembly, so that the first elastic member 220 and the second elastic member 230 can better ensure the pressing hand feeling of the user in the long-side direction of the touch assembly 100 and ensure the detection of the touch pad 10 on the pressing of the user. In addition, the two first elastic arms 221 and the two second elastic arms 231 may be distributed along the short side direction of the rectangular touch assembly, and correspondingly, the two first elastic arms 221 distributed along the short side direction may be connected by the first middle portion 222 distributed along the long side direction, and the two second elastic arms 231 distributed along the short side direction may be connected by the second middle portion 232 distributed along the long side direction, which may also ensure the pressing of the user in the short side direction of the touch assembly 100.

Alternatively, as shown in fig. 5, through holes may be formed in the first middle portion 222 and the second middle portion 232 to reduce the overall weight of the first elastic member 220 and the second elastic member 230, and may provide accommodation space for other devices in the touch pad 10, for example, for components on the lower surface of the circuit board 120.

Alternatively, in other alternative embodiments, the first middle portion 222 and the second middle portion 232 may be solid portions, i.e. no through holes are formed therein, so as to ensure the reliability of the first elastic member 220 and the second elastic member 230, and the setting positions of the solid portions need to avoid other devices in the touch pad 10, such as the devices on the lower surface of the circuit board 120.

Optionally, in the first elastic member 220, at least one first elastic connection member 2221 is disposed at a side of the first middle portion 222 facing the first side 211 of the main support 210, and the first elastic member 220 is connected to the first side 211 of the main support 210 through the at least one first elastic connection member 2221. Correspondingly, at least one second elastic connection element 2222 is disposed on the other side of the first middle portion 222 away from the first edge 211 of the main support 210, and the first elastic element 220 is connected to the fixed platform 240 through the at least one second elastic connection element 2222. As an example, in the embodiment shown in fig. 5, two first elastic connection members 2221 and two second elastic connection members 2222 are provided at both sides of the first middle portion 222, respectively.

The at least one fourth elastic connection 2322 connected to the fixing platform 240 is disposed between the two first elastic arms 221 and located between a first side of the first elastic member 220 near the first side 211 of the main support 210 and a second side far from the first side 211 of the main support 210. When the user presses the touch assembly 100, the at least one fourth elastic connection 2322 may serve as a stress fulcrum of the first elastic member 220.

In some embodiments, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may be integrally formed with the first middle portion 222, and at this time, the at least one first elastic connector 2221 and the at least one second elastic connector 2222 may be understood as a cantilever structure disposed on the first middle portion 222. Alternatively, in other embodiments, the at least one first elastic connection element 2221 and the at least one second elastic connection element 2222 and the first middle portion 222 may be separate structures, and the at least one first elastic connection element 2221 and the at least one second elastic connection element 2222 are connected to the first middle portion 222 by glue layers, welding or other connection methods.

It can be appreciated that after the first elastic member 220 is connected to the first edge 211 of the main support member 210 by at least one first elastic connection member 2221, the first elastic connection member 2221 is suspended except for two end regions, so as to ensure the elastic connection between the first elastic member 220 and the first edge 211 of the main support member 210. After the first elastic member 220 is connected to the fixed platform 240 through the at least one second elastic connecting member 2222, the second elastic connecting member 2222 is in a suspended state except for two end regions, so that the first elastic member 220 can be elastically connected to the first edge 211 of the fixed platform 240.

Similar to the first elastic member 220 described above, in the second elastic member 230, at least one third elastic connection member 2321 is provided at a side of the second middle portion 232 facing the second side 212 of the main support 210, and the second elastic member 230 is connected to the second side 212 of the main support 210 through the at least one third elastic connection member 2321. The other side of the second middle portion 232, which is far from the second edge 212 of the main support 210, is provided with at least one fourth elastic connection 2322, and the second elastic member 230 is connected to the fixing platform 240 through the at least one fourth elastic connection 2322. As an example, in the embodiment shown in fig. 5, two third elastic connection members 2321 and two fourth elastic connection members 2322 are respectively disposed at both sides of the second middle portion 232. Specifically, the relevant designs of the third elastic connection 2321 and the fourth elastic connection 2322 in the second elastic member 230 can be referred to above for the relevant descriptions of the first elastic connection 2221 and the second elastic connection 2222, which are not repeated herein.

Through the technical scheme of the embodiment of the application, the elastic connecting pieces are respectively arranged at the two sides of the first middle part 222 of the first elastic piece 220, and the elastic connecting pieces are respectively arranged at the two sides of the second middle part 232 of the second elastic piece 230, so that the elastic connection between the main support piece 210 and the fixed platform 240 of the first elastic piece 220 and the second elastic piece 230 is realized, and a user drives the first elastic piece 220 and the second elastic piece 230 to deform when pressing the touch assembly 100. The whole mode is easy to realize, the connection area between the first elastic piece 220 and the second elastic piece 230 and the main support piece 210 and the fixed platform 240 is smaller, and the elastic deformation of the first elastic piece 220 and the second elastic piece 230 can be effectively ensured, so that the pressing performance of the touch pad 10 is ensured.

With continued reference to fig. 5, corresponding to the first elastic member 220 and the second elastic member 230 described above, the first attachment member 250 has two first connection arms 251 attached to the upper surfaces of the two first elastic arms 221, and the second attachment member 260 has two second connection arms 261 attached to the upper surfaces of the two second elastic arms 231. The two first connecting arms 251 and the two second connecting arms 261 are corresponding to each other and have a gap, one end of the two first connecting arms 251 facing the two second connecting arms 261 is provided with a first protruding portion 2501 located above the two second elastic arms 231, and one end of the two second connecting arms 261 facing the two first connecting arms 251 is provided with a second protruding portion 2601 located above the two first elastic arms 221.

Specifically, in this embodiment, the two first connection arms 251 of the first attachment 250 are attached to the two first elastic arms 221 of the upper surface of the first elastic member 220 to support and reinforce the two first elastic arms 221. Similarly, the two first connection arms 261 of the second attachment member 260 are attached to the two second elastic arms 231 of the upper surface of the second elastic member 230 to support and reinforce the two second elastic arms 231. Alternatively, the first and second attachment members 250 and 260 may be attached to the upper surfaces of the first and second elastic members 220 and 230, respectively, by means of adhesion, welding, stamping, or the like.

The two first connecting arms 251 are provided with two first protrusions 2501 at one ends thereof facing the two second connecting arms 261, and the two first protrusions 2501 are located above the two second elastic arms 231. In the case that the user presses the touch assembly 100, the two first protrusions 2501 act on the ends of the two second elastic arms 231. The two second connection arms 261 are provided with two second protrusions 2601 toward one ends of the two first connection arms 251, and the two second protrusions 2601 are located above the two first elastic arms 221. In the case where the user presses the touch assembly 100, the two second protrusions 2601 act on the ends of the two first elastic arms 221.

It will be appreciated that the first attachment 250 also has an intermediate portion therein connecting the two first connecting arms 251, and the second attachment 260 also has an intermediate portion therein connecting the two second connecting arms 261. The middle portion of the first attachment member 250 may be attached to the first middle portion 222 of the first elastic member 220 and the middle portion of the second attachment member 260 is attached to the second middle portion 232 of the second elastic member 230.

In the case that the first middle portion 222 and the second middle portion 232 have the through holes, the middle portion of the first attachment member 250 and the middle portion of the second attachment member 260 may be formed with the through holes as well, so as to reduce the overall weight of the first attachment member 250 and the second attachment member 260, and provide accommodating spaces for other devices in the touch pad 10, for example, for the devices on the lower surface of the circuit board 120.

As shown in fig. 5 and 6, the concave portions corresponding to the first convex portions 2501 of the two first connecting arms 251 are used to accommodate the second convex portions 2601 of the two second connecting arms 261. The concave portions corresponding to the second convex portions 2601 of the two second connecting arms 261 are used for accommodating the first convex portions 2501 of the two first connecting arms 251.

Through the technical scheme of this embodiment, the first protruding portion 2501 and the second protruding portion 2601 between the two first connecting arms 251 and the two second connecting arms 261 can be mutually matched, so that no extra space is wasted, and the pressing detection performance of the touch pad 10 is reliably ensured. In some embodiments, at least one component of the support assembly 200 is provided with a pinch point groove that may be used to control the planarity of the at least one component.

As an example, the main support 210, the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260 in the support assembly 200 are all provided with the nip grooves. The pressure point grooves can be arranged on the upper surface and the lower surface of each component so as to adjust the planeness of each component.

Specifically, the excessive flatness of any component of the supporting assembly 200 may result in poor uniformity of the pressing force of the touch pad 10, that is, the pressing force at different positions of the touch pad 10 needs different magnitudes, and the fluctuation of the pressing force may be larger. Therefore, the performance parameters of the touch pad 10 can be further optimized by performing the flatness control design through the pressure point groove, and the user experience is improved.

In some embodiments, the pressure point grooves may be square grooves with sides of 0.15mm, alternatively, the pressure point grooves may be circular grooves or other polygonal grooves with varying depths on the main support 210, the fixed platform 240, the elastic members 220, 230, and the connection members 250, 260. As an example, the depth of the nip slot on the main support 210 may be 0.06mm to 1mm for controlling the flatness of the main support 210 to be less than 0.15mm. The depth of the pressure point groove on the fixed stage 240 may be 0.04mm to 0.08mm, and the user controls the flatness of the fixed stage 240 to be less than 0.05mm. The depth of the nip grooves on the first elastic member 220 and the second elastic member 230 may be 0.02mm to 0.05mm. The depth of the nip grooves on the first attachment member 250 and the second attachment member 260 may be 0.04mm to 0.08mm.

In another alternative embodiment, the pressure point grooves may be formed on both upper and lower surfaces of the whole of two parts of the support assembly 200 for controlling the flatness of the whole of the two parts. As an example, the upper and lower sides of the main support 210 and the fixing platform 240 are provided with the nip grooves, and only one side of the first elastic member 220, the second elastic member 230, the first attachment member 250, and the second attachment member 260 is provided with the nip grooves, i.e., the side of the first elastic member 220 contacting the first attachment member 250 does not have the nip grooves, and the side of the second elastic member 230 contacting the second attachment member 260 does not have the nip grooves.

In some possible embodiments, as shown in fig. 2 to 4 above, the projection of the fixed platform 240 on the plane of the touch device 100 exceeds the touch device 100.

Specifically, each component in the touch assembly 100 is a plate-shaped member, and the plane of the touch assembly 100 may be the plane of the cover plate 110 in the touch assembly 100, or may be the plane of the circuit board 120.

The projection of the fixed platform 240 on the plane of the cover plate 110 may exceed the cover plate 110, and the projection of the fixed platform 240 on the plane of the circuit board 120 may also exceed the circuit board 120. That is, in the embodiment, in the direction parallel to the plane of the touch assembly 100, the fixing platform 240 has a portion beyond the touch assembly 100, so that the fixing platform 240 can have a larger area, thereby having good supporting and protecting effects on the touch assembly 100 and improving the overall stability of the touch pad 10.

In some embodiments, the touch assembly 100 is a rectangular assembly, i.e. the cover plate 110 and the circuit board 120 of the touch assembly 100 are both rectangular. In this case, the projection of the fixed platform 240 on the plane of the touch device 100 exceeds the touch device 100 in the length direction and/or the width direction of the touch device 100.

As an example, as shown in fig. 2 to 4, the fixing platform 240 may extend beyond the touch device 100 in both the length direction and the width direction of the touch device 100. The area of the fixing platform 240 may be larger than the area of any component in the touch assembly 100, and the fixing platform 240 may completely cover the touch assembly 100 from bottom to top. In this example, the fixed platform 240 may provide a more complete protection and support for the touch assembly 100.

Alternatively, in another example, fig. 7 shows a schematic exploded view of another touch pad 10 provided in an embodiment of the present application.

As shown in fig. 7, in the embodiment of the application, the fixing platform 240 may extend beyond the touch device 100 in the width direction of the touch device 100. The fixed platform 240 does not extend beyond the touch device 100 in the length direction of the touch device 100. In this example, the fixing platform 240 does not cover the touch assembly 100 completely from bottom to top, but the overall area of the fixing platform 240 can be reduced appropriately, which is beneficial to reducing the overall weight of the touch pad 10 and reducing the space required by the touch pad 10 in the electronic device.

Optionally, in some embodiments, a portion of the fixed platform 240 beyond the touch assembly 100 is provided with a mounting member for mounting the fixed platform 240 to an electronic device in which the touch pad 10 is located.

By way of example, the mounting elements include, but are not limited to, screw holes and screws, snaps, glue lines, etc. for achieving a connection mounting. Specifically, in the case where the mounting member includes screw holes through which the screws can fixedly mount the fixing platform 240 to the electronic device, the edge region of the fixing platform 240 may be disposed at the screw holes.

When the electronic device where the touch pad 10 is located is a notebook computer, the mounting member may mount the touch pad 10 on a C-shell of the notebook computer, i.e. a shell of a surface where a keyboard is located in the notebook computer. For example, the C-case has a through hole therein for receiving the touch pad 10, and the mounting member may mount the fixing platform 240 to an edge of the through hole such that the touch pad 10 is mounted and received at the through hole of the C-case.

Through the technical scheme of this embodiment, can directly utilize fixed platform 240 to install touch panel 10 in electronic equipment, the whole mounting means easily realizes and the reliability is higher, is favorable to promoting the assembly efficiency of touch panel 10 in electronic equipment, also is convenient for its dismantlement and maintenance.

Fig. 8 shows a schematic structural view of the stationary platform 240 in the embodiment shown in fig. 4 and 7 above.

Wherein fig. 8 (a) corresponds to the fixed platform 240 in the embodiment shown in fig. 4, and fig. 8 (b) corresponds to the fixed platform 240 in the embodiment shown in fig. 7.

As shown in fig. 8, in the embodiment of the present application, a central area of the fixed platform 240 is provided with a protrusion 242 facing the touch assembly 100. The contact 241 may be located in a central region of the boss 242.

Alternatively, the protrusion 242 may be a rectangular protrusion that is adapted to a rectangular space defined by the first elastic member 220 and the second elastic member 230. Alternatively, the contact 241 may be a bump in a central region of the boss 242, and the area and height of the contact 241 may be correspondingly designed according to the travel switch 101 on the circuit board 120 so that the contact 241 can effectively contact and trigger the travel switch 101. As shown in connection with fig. 2 to 8, the first elastic member 220 and the second elastic member 230 may be coupled to the boss 242 to achieve the interconnection of the first elastic member 220 and the second elastic member 230 with the fixed platform 240. And the first elastic member 220 and the second elastic member 230 have a gap with other regions of the fixing platform 240 except the protrusion 242.

Specifically, at least one second elastic connection element 2222 of the first middle portion 222 of the first elastic element 220 may be connected to an edge of the upper surface of the protrusion 242 near the first middle portion 222, so as to achieve interconnection between the first elastic element 220 and the fixing platform 240. At least one fourth elastic connection 2322 on the second middle 232 of the second elastic member 230 may be connected to an upper surface of the boss 242 near an edge of the second middle 232 to achieve interconnection of the second elastic member 230 with the fixing platform 240. It should be understood that the first elastic connection 2221 of the first elastic element 220 and the third elastic connection 2321 of the second elastic element 230 are only connected to the main support 210, respectively, and a gap is formed between each of the first elastic connection 2221 and the second elastic connection 2321 and the fixing platform 240.

In this embodiment, gaps are formed between the first elastic member 220 and the second elastic member 230 and other areas of the fixing platform 240 except for the protruding portion 242, and the gaps can provide deformation spaces of the first elastic member 220 and the second elastic member 230, so that the touch assembly 100 can be displaced downward under the pressing action of a user, and thus the pressing detection function of the touch pad 10 is guaranteed.

Through the technical solution of this embodiment, the protruding portion 242 is disposed in the central area of the fixing platform 240, so that the protruding portion 242 can be matched with the first elastic member 220 and the second elastic member 230 to realize the pressing detection function of the touch pad 10, and the fixing platform 240 is also convenient to have a larger area design, for example, the fixing platform 240 has a portion beyond the touch assembly 100, thereby playing a reliable supporting and protecting role on the touch assembly 100.

Fig. 9 is a schematic diagram showing an assembled structure of the first elastic member 220 and the second elastic member 230 and the fixing platform 240 in the embodiment shown in fig. 4.

As shown in fig. 9, in the embodiment of the present application, the first elastic member 220 and the second elastic member 230 are symmetrically disposed along a direction parallel to the short side of the touch pad 10, and enclose to form an opening area corresponding to the protrusion 242.

Specifically, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230 are disposed at the periphery of the protrusion 242, and when the user presses the touch assembly 100, the protrusion 242 does not interfere with or affect the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230. In addition, the two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 232 of the second elastic member 230 can be uniformly and symmetrically distributed in the touch pad 10 to further improve the pressing uniformity of the touch pad 10, thereby providing balanced force feedback to the user.

The two first elastic arms 221 of the first elastic member 220 and the two second elastic arms 231 of the second elastic member 230 are disposed at the periphery of the two sides of the protrusion 242 parallel to the short side direction of the touch pad 10, and the first middle portion 222 of the first elastic member 220 and the second middle portion 232 of the second elastic member 230 are disposed at the periphery of the two sides of the protrusion 242 parallel to the long side direction of the touch pad 10. The two sides of the protrusion 242 parallel to the longitudinal direction of the touch pad 10 are respectively connected to the first middle portion 222 and the second middle portion 232 through at least one second elastic connection member 2222 and at least one fourth elastic connection member 2322.

By the technical scheme of the embodiment, the protrusion 242 does not interfere with and affect the elastic deformation of the first elastic member 220 and the second elastic member 230, so as to reliably ensure the pressing detection performance of the touch pad 10.

Alternatively, as shown in fig. 8 and 9, the boss 242 in the above-described application embodiment may be a hollow boss. For example, the hollow boss 242 may be a hollow boss formed by press molding the fixing platform 240.

By the technical solution of this embodiment, the protruding portion 242 is easily formed in the fixed platform 240, and the weight of the fixed platform 240 as a whole is small and the cost is low.

Alternatively, in other possible embodiments, the boss 242 may be a solid boss. For example, a solid reinforcing part may be provided on the upper surface of the fixing platform 240, which may not only form a protrusion of the surface of the fixing platform 240, but also improve the connection strength between the fixing platform 240 and the first and second elastic members 220 and 230.

In this embodiment, fig. 10 shows a schematic exploded view of another stationary platform 240 provided by an embodiment of the present application.

As shown in fig. 10, the fixing platform 240 has a plate-shaped structure, and the upper surface thereof may be provided with a reinforcing portion, specifically, the central area of the upper surface thereof may be provided with an "i" shaped reinforcing plate, and the reinforcing plate and the fixing platform 240 may be connected to each other to form a protrusion 242 on the surface of the fixing platform 240.

Alternatively, the stiffening plate may be attached to the fixed platform by various means, such as screws, glue lines, welding, etc. As an example, the stiffening plate shown in fig. 10 is "i" shaped, and in other alternative embodiments, the stiffening plate may be adjusted to other shapes according to actual needs, which is not specifically limited in this embodiment of the present application.

Referring to fig. 8 and fig. 10, in several fixing platforms 240 provided in the embodiments of the present application, one or more through holes are provided, and the through holes may be used to reduce the weight of the fixing platform 240 and may also be used to avoid other components in the electronic device where the touch pad 10 is located, so as to optimize the overall performance of the touch pad 10 and the electronic device where it is located.

Alternatively, in the embodiment shown in fig. 8, the through holes may be provided in the boss 242 of the fixed stage 240, or the through holes may be provided in a non-boss area of the fixed stage 240. In the embodiment shown in fig. 10, the boss 242 may be provided with no through hole as the reinforcing portion, but only the body plate-like portion of the fixing platform 240.

Based on the fixed platform 240 shown in fig. 10, fig. 11 shows a schematic exploded view of another touch pad 10 including the fixed platform 240.

As shown in fig. 11, in the touch pad 10, the functions of the respective components may be the same as those of the embodiments shown in fig. 4 and 7 above. The difference is that the shape design of the parts of the embodiments of the present application differs from the shape design of the parts of the embodiments shown in fig. 4 and 7 above.

Specifically, in the touch pad 10, the relevant design of the fixed platform 240 is different from the relevant design of the fixed platform 240 in the embodiment shown in fig. 4 and 7, and the relevant technical solution of the fixed platform 240 can be seen from the relevant description of the embodiment shown in fig. 10.

In addition, the shape design of the first elastic member 220 and the second elastic member 230 is slightly different from the shape design of the two elastic members in the embodiment shown in fig. 4 and 7. In the embodiment of the present application, the first middle portion 222 of the first elastic member 220 and the second middle portion 232 of the second elastic member 230 are not provided with through holes, but are solid arm structures. The intermediate portions of the first and second attachment members 250 and 260, which are fitted to the solid intermediate portions of the first and second elastic members 220 and 230, are also solid intermediate portions, and are not provided with through holes.

In the embodiment of the application, the touch pad 10 may be mounted to an electronic device, for example, a C-case of a notebook computer, through the fixing platform 240. Although the fixing platform 240 can indirectly support the main support 210 and the touch assembly 100 through the elastic connection members, the stability of the main support 210 and the touch assembly 100 is poor. Moreover, due to manufacturing tolerances and assembly tolerances of the components of the touch pad 10, the overall thickness of the touch pad 10 will also change, and thus the touch assembly 100 will be protruded or recessed after the touch pad 10 is mounted on an electronic device.

In view of this, in some embodiments of the present application, the main support 210 may be further provided with a limiting portion 213 on the basis of a rectangular frame shape, and the limiting portion 213 is used to achieve limiting of the main support 210.

For example, as shown in fig. 11, a limiting portion 213 is provided on the first side 211 and/or the second side 212 of the main support 210. As an example, two limiting portions 213 are provided on each of the first and second sides 211 and 212 of the main support 210. The electronic device in which the touch pad 10 is disposed may be provided with a limiting hole, for example, a limiting hole is provided in a C-case of a notebook computer, and when the touch pad 10 is mounted on the C-case, the limiting portion 213 on the main support member 210 may be accommodated in the limiting hole, so as to ensure that the relative position of the main support member 210 in the C-case is fixed, and prevent the touch assembly 100 connected to the main support member 210 from protruding or sinking in the C-case, which results in poor assembly effect of the touch pad 10 in the C-case. Under the condition of poor assembly effect, the appearance aesthetic degree of the touch pad 10 is affected, and the pressing use experience of a user on the touch pad 10 is also affected. Similar to the main support 210 shown in fig. 11, the main support 210 in the embodiments shown in fig. 4 and 7 above may also be provided with a limiting portion 213 to limit the installation of the main support 210 and the touch assembly 100 connected thereto in an electronic device.

In a specific implementation, the limiting portion 213 may be a protruding portion disposed at the periphery of the frame-shaped body of the main support 210. The shape, size and number of the limiting portions 213 may be designed according to actual requirements. As an example, as shown in fig. 11, four limiting parts 213 may be provided at four corners of the frame-shaped body of the main support 210, thereby performing a more reliable limiting function on the main support 210. The stopper 213 includes, but is not limited to, a block or plate structure. Through the technical scheme of the embodiment, the main support piece 210 is used as a central component in the touch pad 10, so that the overall strength and structural stability of the touch pad 10 are ensured, and the limiting part 213 is arranged on the main support piece 210 to realize the limiting of the main support piece 210 and the touch assembly 100 connected with the main support piece in the electronic equipment, thereby more reliably ensuring the installation and use of the touch pad 10 in the electronic equipment.

In addition to providing a limiting aperture in the C-case of the electronic device that mates with the limiting portion 213 of the main support 210, in other embodiments, a limiting aperture may be provided in the stationary platform 240 to limit the main support 210.

Fig. 12 shows a schematic exploded view and an assembled view of a main support 210 and a stationary platform 240 provided in an embodiment of the present application.

As shown in fig. 12, the fixing platform 240 may be similar to the shape of the fixing platform 240 in fig. 4, except that the edge of the fixing platform 240 in the embodiment of the present application is bent upward to form a step structure 243, and a sidewall of the step structure 243 is formed with a limiting hole 244. The limiting hole 244 can cooperate with the limiting portion 213 of the main support 210 to enable the fixing platform 240 to limit the main support 210.

Through the technical solution of this embodiment, the main support 210 may be limited by using the fixing platform 240 in the touch pad 10, without additionally providing a limiting hole in the electronic device. While ensuring that the main support 210 and the touch assembly 100 connected thereto may have a relatively stable structure, the installation of the touch pad 10 in the electronic device may be simplified, and the disassembly and maintenance thereof may be facilitated.

In some embodiments, the size of the limiting hole 244 is larger than the size of the limiting portion 213 in a direction perpendicular to the touch assembly 100.

After the limiting portion 213 is mounted in the limiting hole 244, the upper surface of the limiting portion 213 may abut against the wall of the limiting hole 244. When a user presses the touch assembly 100, the limiting portion 213 can move downward in the limiting hole 244 along with the main support 210, and the larger limiting hole 244 can provide a certain downward movement space for the limiting portion 213 and limit the downward movement limit of the limiting portion 213, so that the user can press the touch assembly 100 conveniently and prevent the touch assembly 100 from excessively moving downward and collapsing, and the user experience of the user on the touch panel 10 is improved.

Alternatively, in the embodiment shown in fig. 12, the fixed platform 240 may be a rectangular platform, and edges where two short sides of the fixed platform 240 are located are bent upwards to form two strip-shaped step structures 243. The two step structures 243 may correspond to two sides of the main support 210 where the stopper 213 is provided, respectively.

Alternatively, the step surface of the step structure 243 may be provided with mounting members, such as screw holes, screws, etc., for enabling the mounting of the fixing platform 240 in an electronic device.

It will be appreciated that fig. 12 is provided as an illustration only, and that another type of stationary platform 240 having a stepped structure 243 is shown on the basis of the stationary platform 240 of the embodiment shown in fig. 4. In addition to the embodiment shown in fig. 12, the edge of the fixing platform 240 in the embodiment shown in fig. 11 may be bent upward to form a stepped structure 243, and the sidewall of the stepped structure 243 is formed with a limiting hole 244. Alternatively, in the embodiment shown in fig. 7, the side wall of the stepped structure of the fixing platform 240 may be formed with a limiting hole 244 as well.

Alternatively, in the above embodiments, the contact 241 on the fixed platform 240 may be a boss of the boss 242 protruding toward the touch assembly 100. In some related aspects, the boss may also be referred to as a "conductive base". The boss and the boss 242 may be integrally formed, or may be separately formed. In a specific implementation, the boss may be implemented with metal or silicone.

In this embodiment, the fixing platform 240 is used to match with the contact 241 of the travel switch 101, which is simple in implementation and low in manufacturing cost, and is beneficial to improving the production and manufacturing efficiency of the touch pad 10 and reducing the overall manufacturing cost of the touch pad 10.

In addition to the boss of the embodiments of the application described above, fig. 13 shows a schematic diagram of an implementation of another contact 241 provided by an embodiment of the application.

As shown in fig. 13, in an embodiment of the present application, the contact 241 may be an adjustment screw 2411 mounted to the boss 242, the height of the adjustment screw 2411 relative to the boss 242 being adjustable.

Optionally, in cooperation with the adjustment screw 2411, a nut 2412 may be provided on the boss 242 to facilitate installation of the adjustment screw 2411 on the boss 242. The height of the adjusting screw 2411 protruding from the boss 242 through the nut 2412 and protruding from the boss 242 may be adjusted, i.e., the distance and interaction force between the adjusting screw 2411 and the travel switch 101 may be adjusted.

Through the technical scheme of this embodiment, this adjustable height's adjusting screw 2411 can be better be adapted to travel switch 101 for this travel switch 101 is more sensitive and accurate to the response of pressing pressure. In addition, the height-adjustable adjusting screw 2411 can also tolerate the deformation of the fixed platform 240 and the thickness tolerance of the travel switch 101, in other words, even if the fixed platform 240 has deformation and/or the travel switch 101 has thickness tolerance, the distance and the interaction force between the adjusting screw 2411 and the travel switch 101 can be adjusted by the adjusting screw 2411, so as to ensure good cooperation between the travel switch 101 and the adjusting screw 2411, thereby ensuring the pressing detection performance of the touch pad 10.

Fig. 14 shows a schematic diagram of an implementation of another contact 241 provided in an embodiment of the present application.

As shown in fig. 14, in the present embodiment, the contact 241 is a T-shaped screw 2413 disposed on the boss 242, the head of the T-shaped screw 2413 faces the travel switch 101, and the T-shaped screw 2413 is fixed to the opening 2421 in the boss 242 by an adhesive layer 2414.

Specifically, the boss 242 may have an aperture 2421 formed therein, and the aperture 2421 may have a bore diameter that is greater than the diameter of the shaft of the T-screw 2413 and less than the diameter of the head of the T-screw 2413. In this case, the shaft of the T-screw 2413 may pass through the aperture 2421, but the head of the T-screw 2413 is restrained above the aperture 2421.

In the assembly process of the touch pad 10, the head of the T-shaped screw 2413 may abut against the travel switch 101, and the pre-pressing device may apply a preset force to the bottom of the T-shaped screw 2413, where the preset force may be adjusted and designed according to the actual pressing force of the user pressing the touch pad 10. Under the pre-pressing force, the T-shaped screw 2413 and the travel switch 101 may be in a pre-pressed state, which can sensitively detect the pressing of the user on the touch pad 10.

While the pre-compression device applies a pre-set force to the bottom of the T-screw 2413, in order to enable the T-screw 2413 to maintain a pre-compression state, a glue layer 2414 may be formed by dispensing glue in the opening 2421, thereby securing the T-screw 2413 to the opening 2421. The head of the T-shaped screw 2413 can prevent the glue layer 2414 from overflowing to the travel switch 101, and ensure reliable use of the travel switch 101.

Through the technical scheme of the embodiment, the distance and the interaction force between the T-shaped screw 2413 and the travel switch 101 do not need to be adjusted through the adjusting screw 2411, and the T-shaped screw 2413 and the travel switch 101 can be kept in a prepressing state which is adaptive to the pressing action of a user through the mutual matching of the T-shaped screw 2413 and the adhesive layer 2414, so that the pressing of the user on the touch pad 10 can be detected more sensitively and conveniently, and the pressing hand feeling of the user on the touch pad 10 can be ensured.

It will be appreciated that the related technical solutions of the adjusting screw 2411 and the T-shaped screw 2413 shown in fig. 13 and 14 may also be applied to any of the embodiments shown in fig. 2 to 12, that is, the boss where the contact 241 is located in any of the embodiments shown in fig. 3 to 12 is replaced by the adjusting screw 2411 or the T-shaped screw 2413.

As an example, fig. 15 shows a schematic exploded view of another touch pad 10 provided in an embodiment of the present application, based on the embodiment shown in fig. 4.

As shown in fig. 15, in the fixed stage 240, the boss of the contact 241 in the embodiment shown in fig. 4 is replaced with an adjustment screw 2411, and the center region of the boss 242 is provided with a nut 2412 to fit the installation of the adjustment screw 2411 in the boss 242.

In addition, in the embodiment shown in fig. 15, the touch pad 10 may include a conductive cloth 300 in addition to the components of the touch assembly 100 and the support assembly 200 in the above embodiment.

The conductive cloth 300 may be connected to the circuit board 120 in the touch assembly 100 and the main support 210 in the support assembly 200. The conductive cloth 300 can be used for guiding the static electricity generated on the circuit board 120 out of the touch pad 10 through the main supporting member 210, so as to prevent the static electricity from damaging each component in the touch pad 10.

It will be appreciated that the conductive cloth 300 may be applied to any of the embodiments shown in fig. 2-14 above in addition to the embodiment shown in fig. 15 to provide electrostatic protection to the touch pad 10 of each embodiment.
