Description

Technical Field

[0001] The present invention relates to the technical field of touch panel vibration feedback systems, and more specifically, to a piezoelectric ceramic touch panel vibration feedback system and an assembly method thereof. Background Art

[0002] With the development of touch technology, touch panels integrating capacitive touch films, pressure sensors and piezoelectric ceramic vibrators are widely used in various electronic devices. Among them, piezoelectric ceramic vibrators are key components for providing vibration feedback, and their installation accuracy directly affects the feedback performance and user experience of the entire touch panel.

[0003] However, in the actual production process, due to the tolerances of different piezoelectric ceramic components, ensuring that multiple piezoelectric ceramic components can be accurately assembled has always been a challenge in the industry. Figure 1 As shown, for the piezoelectric ceramic touch panel vibration feedback system, multiple piezoelectric ceramic elements 3' are assembled between the supporting shell 2' and the vibration surface 1', and each piezoelectric ceramic element 3' needs to be tightly fitted with the vibration surface 1' and the supporting shell 2' on the upper and lower surfaces respectively. In order to meet this technical requirement, the traditional assembly method usually relies on precision machining of piezoelectric ceramic elements to minimize the tolerance of each piezoelectric ceramic element to ensure that the piezoelectric ceramic element can be tightly fitted to the installation surface (including the lower surface of the vibration surface and the upper surface of the supporting shell).

[0004] However, this existing method has the following technical defects:

[0005] 1. High cost: The use of high-precision machinery required to process piezoelectric ceramic components will significantly increase production costs;

[0006] 2. Low efficiency: Precisely controlling the tolerance of each piezoelectric ceramic component has a significant impact on production efficiency, making it difficult to meet the needs of large-scale production;

[0007] 3. Difficulty in assembly: Even if high-precision mechanical processing of piezoelectric ceramic components is used, it is difficult to ensure that each piezoelectric ceramic component meets the expected accuracy standards during the mass manufacturing process; therefore, during the assembly process, due to tolerance accumulation, it is often difficult to ensure that all piezoelectric ceramic components can be completely close to the installation surface, thus affecting the consistency of product performance.

[0008] Based on this, there is an urgent need for an efficient assembly method for a piezoelectric ceramic touch panel vibration feedback system that can ensure that all piezoelectric ceramic elements can completely fit tightly against the mounting surface. Summary of the invention

[0012] In addition, a preferred solution is that a sliding hole corresponding to the upper and lower parts of the second piezoelectric ceramic element is opened on the support shell, and the height adjustment locking member includes a slider slidably connected to the sliding hole; wherein, after the slider slides in the sliding hole to adjust the height and is locked, the upper and lower surfaces of the second piezoelectric ceramic element are respectively tightly attached to the vibration surface and the slider.

[0013] In addition, a preferred solution is that the height adjustment locking member further includes adhesive, and after the slider slides in the slide hole to adjust the height, the slider is bonded and locked by the adhesive.

[0018] In addition, a preferred solution is that the second piezoelectric ceramic element includes a second piezoelectric ceramic body and second elastic sheets arranged on the upper and lower sides of the second piezoelectric ceramic body, wherein:

[0019] The second elastic sheets on the upper and lower sides of the second piezoelectric ceramic body are respectively in close contact with the vibration surface and the height-adjusting locking member.

[0020] In addition, a preferred solution is that both the first elastic sheet and the second elastic sheet are elastic steel sheets.

[0021] On the other hand, the present invention also provides a method for assembling the piezoelectric ceramic touch panel vibration feedback system as described above, the method comprising:

[0038] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Figure 2 The flowchart of the steps of the assembly method of the piezoelectric ceramic touch panel vibration feedback system provided by the embodiment of the present invention is shown. Figure 2 As can be seen from the last step diagram (showing the structure of the piezoelectric ceramic touch panel vibration feedback system provided by the embodiment of the invention), the piezoelectric ceramic touch panel vibration feedback system provided by the present invention mainly includes a supporting shell 2 at the bottom and a vibration surface 1 at the top of the supporting shell 2. The supporting shell 2 and the vibration surface 1 usually need to be arranged in parallel. The supporting shell 2 is usually a hard plastic part, which serves as the basic carrier of the entire piezoelectric ceramic touch panel vibration feedback system. The vibration surface 1 is usually used to form the overall process of the touch panel (such as a touch screen). A vibration gap is formed between the supporting shell 2 and the vibration surface 1. First piezoelectric ceramic elements 3 are arranged at both ends of the vibration gap between the supporting shell 2 and the vibration surface 1. The upper and lower surfaces of the first piezoelectric ceramic elements 3 at the two ends are respectively in close contact with the vibration surface 1 and the supporting shell 2, thereby achieving the touch feedback performance of the end position of the vibration surface 1 and the preliminary fixation of the vibration surface 1.

[0041] In order to achieve the touch feedback performance at the middle position of the vibration surface 1, a second piezoelectric ceramic element 7 is arranged between the first piezoelectric ceramic elements 3 at both ends. It should be noted that after the upper and lower surfaces of the two ends are respectively in close contact with the vibration surface 1 and the support shell 2, the vibration surface 1 will be initially fixed, and the height of each position in the vibration gap will be determined. However, since the sizes of each second piezoelectric ceramic are slightly different during the manufacturing process, there is a tolerance. Therefore, if the second piezoelectric ceramic element 7 is directly placed at the corresponding position in the vibration gap, it is difficult to ensure that each second piezoelectric ceramic element 7 is in close contact with the installation surface; for this reason, the piezoelectric ceramic touch panel vibration feedback system provided by the present invention is provided with a height adjustment locking piece corresponding to the upper and lower sides of the second piezoelectric ceramic element 7 on the support shell 2; wherein, the height of the height adjustment locking piece is adjustable, and the position can be locked after the height is adjusted. After the height adjustment locking piece is adjusted and locked, it can be ensured that the upper and lower surfaces of each second piezoelectric ceramic element 7 are in close contact with the vibration surface 1 and the height adjustment locking piece respectively.

[0042] In a specific embodiment of the present invention, in order to realize the production of a height-adjusting locking piece, a sliding hole 5 corresponding to the upper and lower parts of the second piezoelectric ceramic element 7 can be opened on the supporting shell 2, and the sliding hole 5 runs through the entire supporting shell 2. The height-adjusting locking piece includes a slider 4 slidably connected to the sliding hole 5. By pushing each slider 4 on the back side of the supporting shell 2, the slider 4 can be slid in the sliding hole 5 to adjust the height. After the slider 4 slides in the sliding hole 5 to adjust the height and is locked, it can be ensured that the upper and lower surfaces of the second piezoelectric ceramic element 7 are tightly attached to the vibration surface 1 and the slider 4, respectively.

[0043] Furthermore, in order to achieve the locking effect of the height-adjusting locking member, the height-adjusting locking member may also include adhesive, and after the slider 4 slides in the slide hole 5 to adjust the height, the slider 4 is bonded and locked by the adhesive. It should be noted that the adhesive may be glue, and a precise amount of glue is used to fill the gap between the slider 4 and the support shell 2 to achieve permanent fixation of the slider 4; the adhesive may also be a rubber strip, and the slider 4 and the support shell 2 are bonded and fixed by the rubber strip.

[0044] In addition, in order to achieve touch feedback performance at each middle position of the vibration surface 1, multiple (at least one) second piezoelectric ceramic elements 7 need to be arranged between the two first piezoelectric ceramic elements 3; and, the first piezoelectric ceramic elements 3 at both ends and each second piezoelectric ceramic element 7 are distributed at equal intervals between the support shell 2 and the vibration surface 1.

[0045] It should be emphasized that the above embodiments of the present invention are Figure 2The description is based on the vertical cross-section of a product shown in the figure. However, in the actual assembly process, the vibration surface 1 and the supporting shell 2 are both planar structures. Therefore, a group of first piezoelectric ceramic elements 3 (multiple first piezoelectric ceramic elements 3) need to be set at both ends of the vibration gap between the supporting shell 2 and the vibration surface 1. At this time, multiple groups of corresponding second piezoelectric ceramic elements 7 also need to be set, and the first piezoelectric ceramic elements 3 at both ends and the second piezoelectric ceramic elements 7 will be distributed in a matrix between the supporting shell 2 and the vibration surface 1.

[0046] For the piezoelectric ceramic element (including the first piezoelectric ceramic element 3 and the second piezoelectric ceramic element 7), in order to achieve its piezoelectric sensing performance, it usually includes a piezoelectric ceramic body in the middle and elastic sheets on the upper and lower sides of the piezoelectric ceramic body; for example, the first piezoelectric ceramic element 3 may include a first piezoelectric ceramic body 31 and a first elastic sheet (i.e., an upper first elastic sheet 32 ​​and a lower first elastic sheet 33) arranged on the upper and lower sides of the first piezoelectric ceramic body, and the first elastic sheets on the upper and lower sides of the first piezoelectric ceramic body are respectively in close contact with the vibration surface 1 and the support shell 2. For another example, the second piezoelectric ceramic element 7 includes a second piezoelectric ceramic body (not marked in the figure) and a second elastic sheet (not marked in the figure) arranged on the upper and lower sides of the second piezoelectric ceramic body, wherein the second elastic sheets on the upper and lower sides of the second piezoelectric ceramic body are respectively in close contact with the vibration surface 1 and the height adjustment locking member.

[0047] In the actual manufacturing process, in order to ensure that the first elastic sheet and the second elastic sheet can have the required elastic effect and guiding performance, the first elastic sheet and the second elastic sheet can both be made of elastic steel sheets.

[0048] To explain in detail the assembly process of the electric ceramic touch panel vibration feedback system provided by the present invention, Figure 2 As shown, the present invention also provides an assembly method of a piezoelectric ceramic touch panel vibration feedback system. In a specific embodiment of the present invention, the method comprises the following steps:

[0049] Prepare a support shell 2, a vibration surface 1, a first piezoelectric ceramic element 3 and a second piezoelectric ceramic element 7, and set a height-adjusting locking piece on the support shell 2;

[0050] The first piezoelectric ceramic elements 3 at both ends and the second piezoelectric ceramic elements 7 are respectively arranged at corresponding preset positions between the support shell 2 and the vibration surface 1; wherein, it is necessary to ensure that the first piezoelectric ceramic elements 3 at both ends are accurately installed at the predetermined positions through mechanical processing or adjustment mechanism, and the upper and lower surfaces thereof need to be tightly fitted with the vibration surface 1 and the support shell 2 respectively;

[0051] By adjusting the height of each height-adjusting locking member, the upper and lower surfaces of each second piezoelectric ceramic element 7 are respectively in close contact with the vibration surface 1 and the height-adjusting locking member, and the pressure is maintained for a certain preset time manually or with an auxiliary device;

[0052] Lock the height locking piece in position.

[0053] Furthermore, in order to achieve height adjustment of the height-adjusting locking piece, a sliding hole 5 corresponding to the upper and lower parts of the second piezoelectric ceramic element 7 can be opened on the supporting shell 2, and the height-adjusting locking piece includes a slider 4 slidably connected in the sliding hole 5; and, by adjusting the height of each height-adjusting locking piece, the upper and lower surfaces of each second piezoelectric ceramic element 7 are respectively in close contact with the vibration surface 1 and the height-adjusting locking piece, including: sliding the corresponding slider 4 up and down in each sliding hole 5 to achieve fine-tuning and preliminary positioning of each slider 4, and compensating for the tolerance of each second piezoelectric ceramic element 7 through the fine-tuning function of the slider 4, so that the upper and lower surfaces of each second piezoelectric ceramic element 7 are respectively in close contact with the vibration surface 1 and the corresponding slider 4.

[0054] Furthermore, in order to achieve position fixation of the height adjustment locking piece, the height adjustment locking piece also includes adhesive glue; and the position locking of the height adjustment locking piece includes: using adhesive glue 6 to bond and fix each slider 4 to ensure that each second piezoelectric ceramic element 7 in the entire piezoelectric ceramic touch panel vibration feedback system can continue to maintain a close fit after assembly.

[0055] It can be seen from the above specific embodiments that the piezoelectric ceramic touch panel vibration feedback system and assembly method thereof provided by the present invention have at least the following advantages:

[0056] 1. The piezoelectric ceramic touch panel vibration feedback system provided by the present invention is provided with a height adjustment locking piece corresponding to each intermediate piezoelectric ceramic on the support shell, and the height adjustment locking piece can be adjusted to ensure that the upper and lower surfaces of each intermediate piezoelectric ceramic can be fitted with the mounting surface, which significantly reduces the dependence on the tolerance of a single piezoelectric ceramic element and improves the assembly flexibility and fault tolerance of the piezoelectric ceramic touch panel vibration feedback system;
