Detailed Description

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model.

As shown in fig. 1, a conventional touch module 100 is provided^，(before modification) arrangement. The touch module 100^，The middle vibration feedback element 3 is disposed below the touch pad 1, so the vibration feedback element 3 will occupy the space of the touch pad 1 in the vertical direction (Z direction, i.e. up-down direction) of the touch surface, and such an arrangement is not beneficial to the whole touch module 100^，The design requirement of lightness and thinness (before improvement).

Therefore, the present invention provides a novel touch module 100 (after improvement), as shown in fig. 2 to 5, by disposing the vibration feedback element 3 outside the touch pad 1, an external arrangement is realized, so that the vibration feedback element 3 does not occupy the space of the touch pad 1 in the thickness direction (up-down direction), the ultra-thin design of the touch pad 1 is realized, and the market competitiveness of the whole product is improved.

The touch module 100 is configured to further include a bracket 2. The bracket 2 is fixed to one side of the touch panel 1, and may be fixed to one side of a non-touch surface (i.e., a non-exterior surface) of the touch panel 1. The bracket 2 may be formed in a thin plate shape to reduce the overall thickness of the entire touch module 100 to the maximum. The bracket 2 may be configured to include a fixed plate 21 and an extension plate 22. Wherein, a partial area or the whole area of the extension plate 22 extends out of the touch pad 1, that is, the extension plate 22 extends out of a partial area of the touch pad 1 to form an extension portion 23.

The vibration feedback element 3 is fixed to the extension 23, i.e. an external arrangement of the vibration feedback element 3 is achieved. The vibration feedback element 3 and the touch pad 1 may be disposed on different sides of the support 2, as shown in fig. 2, the touch pad 1, the support 2, and the vibration feedback element 3 are arranged in sequence from top to bottom. The vibration feedback element 3 and the touch pad 1 may also be disposed on the same side of the support 2 to meet the layout requirements of different touch modules 100. The vibration feedback element 3 can provide vibration to the support 2 in a certain direction, for example, in a direction perpendicular to the touch pad 1, or in a direction parallel to the surface of the touch pad 1, as shown by the dashed arrow in fig. 2 (the vibration direction can be collinear with or parallel to the central axis of the extension board 22). The vibration is transmitted to the touch pad 1 through the support 2 to realize the vibration feedback of the entire touch module 100, and the vibration feedback element 3 can be a piezoelectric actuator, so that the entire touch module 100 has a wider operating frequency band and a shorter response time.

The touch module 100 further includes a pressure sensor (not shown) disposed below the touch pad 1, i.e., on a side close to the support 2. The pressure sensor may be disposed in an area between the touch pad 1 and the support 2. The pressure sensor is arranged to detect the touch pressure received by the touch pad 1, and the detected pressure value can be transmitted to the control module in the touch module 100 in real time.

In some exemplary embodiments, as shown in fig. 2 to 4, the fixing plate 21 of the bracket 2 is used to be attached to the touch pad 1, so as to fix the bracket 2 and the vibration feedback element 3. The fixing plate 21 may be rectangular, and the length direction of the fixing plate 21 and the length direction of the touch pad 1 may be designed to be the same, that is, the length directions of the fixing plate and the touch pad are parallel to each other, so as to increase the contact area between the fixing plate 21 and the touch pad 1 and improve the uniformity of vibration feedback. The extension plate 22 may be configured to be rectangular, and its length direction extends toward the outer side of the touch pad 1, so that a part or the whole of the area extends out of the touch pad 1. The extension plate 22 may be vertically fixed at the middle of the fixing plate 21, i.e., the connection position is not the edge of the fixing plate 21, but may not be the center of the fixing plate 21, but only near the center area of the fixing plate 21. Wherein, the extension portion 23 can be configured such that the extension plate 22 extends out of a portion of the area of the touch pad 1. As shown in fig. 2, an extension 23 may be provided at the position of the outer edge of the extension plate 22.

The support 2 is designed in a differentiation mode according to different implementation functions, and the feedback area of vibration response is effectively guaranteed. In addition, the support 2 and the touch pad 1 form surface contact, so that the problem of uniformity of vibration feedback is solved. Moreover, the overall structure of the bracket 2 is reasonably designed, and the weight and the occupied area of the bracket 2 are effectively reduced.

In some exemplary embodiments, the vibration feedback element 3 may be fixed on the extension 23 in a transverse or longitudinal manner, as shown in fig. 2 to 5, and the technical solution is illustrated by a longitudinal arrangement. The longitudinal direction here means that the central axis of the vibration feedback element 3 is substantially in the same direction as the central axis of the extension 23, and the transverse direction means that the central axis of the vibration feedback element 3 is substantially perpendicular to the central axis of the extension 23. Transverse or longitudinal fixing means to accommodate different extension 23 dimensions and the external dimensions of the vibration feedback element 3, increasing the flexibility of mounting the vibration feedback element 3.

In some exemplary embodiments, as shown in fig. 2 to 4, the fixing plate 21 and the extension plate 22 are provided as an integrally formed structure. For example, the frame 2 may be made from a sheet of material by a simple cutting operation. The parts of the bracket 2 are designed to be integrally formed, so that the total number of parts can be reduced, and the management of products and the assembly cost can be reduced. Furthermore, the bracket 2 can have high dimensional accuracy and rigidity and strength to realize the optimization of design.

In some exemplary embodiments, as shown in fig. 2 to 4, the fixing plate 21 and the extension plate 22 may be designed to have a T-shape. One end of the extension plate 22 is connected to the center of the fixing plate 21, and the other end extends away from the touch pad 1, so that all or a part of the extension plate 22 extends out of the touch pad 1. Since the vibration feedback element 3 is disposed at the end of the extension board 22, when the vibration feedback element 3 vibrates, the vibration is gradually transmitted to the touch pad 1 through the T-shaped support 2, so that the point vibration is converted into the surface vibration, and the uniformity of the whole surface vibration of the touch pad 1 is effectively improved.

In some exemplary embodiments, as shown in fig. 2 and 5, the touch pad 1 is close to the end surface of the vibration feedback element 3, and does not abut against the vibration feedback element 3 along the direction in which the bracket 2 extends out of the touch pad 1, that is, the end surface of the touch pad 1 and the vibration feedback element 3 have a spacing L as shown in the figure, so as to form an avoidance space. When the touch module 100 is used in an electronic device, the setting of the interval L can be used to avoid the middle frame 300 between the keyboard 200 and the touch pad 1. The interval L is set to prevent the middle frame 300 from being cut off by the touch module 100, thereby preventing the rigidity of the middle frame 300 from being adversely affected.

In some exemplary embodiments, a partial area of the bracket 2 may be adhered to the touch pad 1 by glue, and the fixing manner is simple to operate and the installation is firm and reliable.

Alternatively, the bracket 2 is fixed on the touch pad 1 by using an smt (surface Mount technology) method. SMT is a surface mounting technology, and products produced by the method have the characteristics of high mounting density, small product volume, light weight, high reliability and the like.

In some exemplary embodiments, the vibration feedback element 3 is glued to the extension plate 22 of the support 2 in a simple manner and securely mounted. The fixing mode same as that of the bracket 2 is selected, so that the switching time among different installation modes is avoided, the assembly period of the product is shortened, and the production efficiency of the product is improved.

In some exemplary embodiments, the bracket 2 may be made of a metal material, such as aluminum, copper, or the like. The bracket 2 is made of metal, so that on one hand, the cost is low due to sufficient raw material resources, and on the other hand, the metal has high rigidity, so that the service lives of the touch module 100 and the whole product can be prolonged.

In some exemplary embodiments, as shown in fig. 2 to 4, the touch pad 1 may be configured as a rectangle, wherein the extension portion 23 is located on at least one side of the touch pad 1, and may be only one side, or two sides, etc. The extension portion 23 may be disposed to extend from a short side or a long side of the rectangular touch pad 1. When the size of the touch pad 1 is large, the two brackets 2 may be disposed opposite to each other, and the extension plates 22 of the two brackets 2 may extend in opposite directions. Through different arrangement forms, the types of the touch module 100 are enriched, the touch module is suitable for the layout of different complete machine products, the flexible application capability of the touch module 100 is improved, and the market competitiveness of the complete machine products is improved.

Another embodiment of the present application, as shown in fig. 5, further provides an electronic device. The electronic equipment can be a mobile phone, a notebook computer or vehicle-mounted multimedia and the like. The electronic device includes the touch module 100, the keyboard 200 and the middle frame 300 according to any of the embodiments. The middle frame 300 is located between the keyboard 200 and the touch pad 1, and the avoiding space is used for avoiding the middle frame 300.
