Description

Technical Field

[0001] The utility model relates to the technical field related to air conditioners, and in particular to an air-touch key assembly for an air conditioner, a wire controller and the air conditioner. Background Art

[0002] The control panel products currently used in the commercial air-conditioning industry are usually called wire controllers, which are generally divided into three levels: full touch screen, touch button screen, and mechanical button screen. Mechanical buttons have a good feel, but are limited by mechanical life and cannot keep up with the development of the times, and have gradually been eliminated. Full touch screens are highly operable, but the cost is very high and the user group is small. In order to improve customer experience, touch button screens are often used. The operation mode of this type of wire controller is capacitive touch button operation. The principle of capacitive touch buttons is to detect the changes in the inductive capacitance generated by the user touching the product operation interface to determine whether the wire controller is being operated.

[0003] There are many ways to touch buttons, such as keypads, flexible circuit boards, touch springs, conductive foam, and air touch buttons. Each method has its own advantages and disadvantages and is widely used. The keypad method has high costs, and the connection between the keypad and the main control board mostly requires plug-in terminals, and the structural installation will be limited. If the space does not allow, the keypad method cannot be used. Flexible circuit board method: Generally, the touch buttons are integrated on the touch panel and connected to the main control board by wiring. The cost is relatively high, and welding or easy damage will cause the touch buttons to fail, and the touch anti-interference ability is weak. Spring and conductive foam method: There are many manual mounting processes, and it is difficult to ensure the consistency of the mounting process. The failure of the spring and the extrusion of the conductive foam will make the touch easily interfered. Air touch button: The cost is relatively low. If the touch threshold is not adjusted well, the anti-interference ability will also be relatively weak.

[0004] At present, the methods to improve the anti-interference ability of touch keys are as follows: by detecting the untouched electrical signal data of the touch keys within a certain period of time when the touch keys are not touched, calculating the interference frequency based on the electrical signal data, adjusting the sampling frequency of the touch keys to ≥ 2 times the interference frequency, sampling the electrical signal data of the touch keys within the sampling frequency, and comparing it with the preset threshold range to determine whether the keys are triggered, thereby reducing the probability of false touches and improving the anti-interference ability. That is, the anti-interference ability of many touch screens is also improved by adjusting the touch firmware and frequency modulation. Similarly, the above-mentioned problems also exist in the air-to-air touch key assembly directly installed on the air conditioner body. Utility Model Content

[0047] Figure 1 is a schematic structural diagram of a spaced touch button assembly for an air conditioner according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figure 2 and Figure 3 The embodiment of the utility model provides a spaced touch button assembly 100 for an air conditioner, which may include a touch control board 20, a touch portion 30 and a shielding layer 40. A conductive pad 21 for generating a touch signal is provided on the touch control board 20. The touch portion 30 is provided on one side of the conductive pad 21, and has a touch button for cooperating with the conductive pad 21, so that when a hand touches the touch button of the touch portion 30, the hand cooperates with the conductive pad 21 to generate a touch signal. The shielding layer 40 is provided on the side of the touch control board 20 away from the touch portion 30; and the projection of the conductive pad 21 on the plane where the shielding layer 40 is located is on the shielding layer 40.

[0048] In this embodiment, since a shielding layer 40 is provided on the back of the conductive pad 21, interference from the rear side of the conductive pad 21 will basically not interfere with the conductive pad 21 under the action of the shielding layer 40. That is to say, in this embodiment, by providing the shielding layer 40, the interference on the back side of the touch button can be shielded to improve the anti-interference ability of the air touch button assembly 100. Moreover, because the touch control board 20 is directly used to integrate the touch button pad, that is, the conductive pad 21 is directly used to detect and generate a touch signal, and the touch button is realized by the air touch of the touch part 30, the cost can be reduced. At the same time, there is no need for a key board and a flexible flat cable, nor a spring and a conductive foam, which has a cost advantage.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a tin-plated layer 22 is provided on the side of the conductive pad 21 facing the touch portion 30, and the tin-plated layer 22 completely covers the conductive pad 21. Because the conductive pad 21 is covered by the tin-plated layer 22, the air near the conductive pad 21 will not oxidize the conductive pad 21, etc., which can include the detection effect of the conductive pad 21 to ensure the accuracy of touch control. That is, in this embodiment, because the tin-plated layer 22 is provided on the conductive pad 21, the conductive pad 21 is a tin-plated pad, which can avoid the conductive pad 21 from being exposed, avoid the touch button failure caused by oxidation, and improve the anti-interference ability to a certain extent. Further, the conductive pad 21 is made of copper.

[0050] In some embodiments of the present invention, there are multiple conductive pads 21. There are multiple shielding layers 40, and each shielding layer 40 is arranged corresponding to a conductive pad 21. The conductive pads 21 and the shielding layers 40 are arranged one by one, which not only can play a shielding role, but also facilitates the flexible setting of the position and spacing of the conductive pads 21, so that the product can be diversified.

[0051] In some alternative embodiments of the present invention, there are multiple conductive pads 21, and the projections of the multiple conductive pads 21 on the plane where the shielding layer 40 is located are all on the shielding layer 40. By providing a shielding layer 40 to shield all interference to the conductive pads 21, the shielding area is larger and the shielding effect is better.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, there are multiple conductive pads 21 arranged into multiple groups, each group of conductive pads 21 includes at least two conductive pads 21, and there are multiple shielding layers 40, each group of conductive pads 21 is arranged corresponding to a shielding layer 40. This arrangement can make the arrangement of the conductive pads 21 and the shielding layer 40 more reasonable, which is convenient for the design of the air touch button assembly, the wire controller, the air conditioner, etc.

[0053] In some embodiments of the utility model, the projection of the conductive pad 21 on the plane where the shielding layer 40 is located is spaced apart from the edge of the shielding layer 40. The shielding effect is improved by setting a larger shielding layer 40 and keeping the conductive pad 21 as far away from the edge of the shielding layer 40 as possible.

[0054] In some embodiments of the present invention, Figure 3 As shown, the shielding layer 40 is in a grid-like structure. The shielding layer 40 is made of a conductive material, and the conductive material is copper foil. The shielding layer 40 is electrically connected to the ground of the touch control board 20. By setting a grid-like structure, the shielding effect can be achieved, and it is also convenient to shield interference signals. In some alternative embodiments of the utility model, the shielding layer 40 can be in a solid plate-like structure, that is, the shielding layer 40 is a shielding plate or a shielding sheet.

[0055] In some embodiments of the present invention, the shielding layer 40 is disposed on the touch control board 20, which has high production efficiency in terms of design and manufacturing. In other embodiments of the present invention, the shielding layer 40 is spaced apart from the touch control board 20.

[0056] In some embodiments of the present invention, Figures 4 to 10 As shown, the touch portion 30 includes a pressing block 31 for supporting the touch button, and the pressing block 31 is aligned with the conductive pad 21. Further, in order to ensure the pressing effect and reduce the pressing interference, that is, to improve the touch stability performance of the touch button, the pressing block 31 includes a first rib 311 and a second rib, and the first rib 311 and the second rib 312 are cross-arranged so that the projection of the pressing block 31 on the conductive pad 21 includes at least one grid.

[0057] Specifically, in some embodiments of the present invention, each first rib 311 is connected end to end, there are multiple first ribs 311, and one of any two first ribs 311 is located in a ring formed by another first rib 311. By providing a multi-ring structure and using the second ribs 312 to radially connect the multi-ring structure, the stability of the user's touch and press can be ensured, and the structure is firm, which significantly reduces materials and costs compared to a solid block structure.

[0058] In other embodiments of the utility model, the multi-circle structure can be cut off to a certain extent, and the remaining part is the pressing block 31, so as to reasonably utilize the space while ensuring the pressing stability. Furthermore, the cut-off part can be connected by ribs to ensure the pressing stability and structural strength.

[0059] For example, in some embodiments of the present invention, Figure 8As shown, there are a plurality of first ribs 311, and the plurality of first ribs 311 include a third rib 313 and a fourth rib 314. The fourth rib 314 is connected end to end, and the third rib 313 is arranged on the outside of the fourth rib 314. The two ends of the third rib 313 are arranged on the outside of the fourth rib 314 at intervals, or the two ends of the third rib 313 are connected to the same position on the fourth rib 314, or the two ends of the third rib 313 are connected to two different positions on the fourth rib 314, or the two ends of the third rib 313 are connected and simultaneously connected to the same position on the fourth rib 314, as shown in FIG. Fig. 9 Further, the first rib 311 further includes at least one seventh rib 315, which is connected end to end and arranged inside the fourth rib 314. In some embodiments, there are multiple seventh ribs 315, and the multiple seventh ribs 315 are arranged on the inner side of the fourth rib 314 in sequence.

[0060] In other embodiments of the present invention, Fig.10 As shown, there are multiple first ribs 311, and the multiple first ribs 311 include a fifth rib 316 and a sixth rib 317, the fifth rib 316 is connected end to end, and the sixth rib 317 is arranged on the inner side of the fifth rib 316; wherein, both ends of the sixth rib 317 are connected to the same position on the fifth rib 316, or both ends of the sixth rib 317 are connected to two different positions on the fifth rib 316, or both ends of the sixth rib 317 are connected and simultaneously connected to the same position on the fifth rib 316. Further, the first rib 311 also includes at least one eighth rib 318, the eighth rib 318 is connected end to end, and is arranged on the inner side of the sixth rib 317. In some embodiments, there are multiple eighth ribs 318, and the multiple eighth ribs 318 are sequentially arranged on the inner side of the sixth rib 317.

[0061] In some alternative embodiments of the present invention, the first ribs 311 are straight and multiple and are arranged in parallel. The second ribs 312 are straight and multiple and are arranged in parallel.

[0062] In some embodiments of the present invention, the touch unit 30 further includes a mounting plate 32 , and the pressing block 31 is disposed between the mounting plate 32 and the conductive pad 21 ; the pressing block 31 is mounted on the mounting plate 32 .

[0063] In some preferred embodiments of the present invention, the pressing block 31 is integrally formed with the mounting plate 32. The pressing block 31 can be made of plastic material, which is low in cost and light in weight.

[0064] In some embodiments of the present invention, the mounting plate 32 is directly a touch panel for touch. In other embodiments of the present invention, a touch panel for touch can be installed on the outer side of the mounting plate 32. The touch panel is made of acrylic or glass. The touch button can touch a certain area on the panel.

[0065] The embodiment of the utility model further provides a wire controller for an air conditioner, which includes the air touch button assembly 100 in any of the above embodiments.

[0066] In some embodiments of the present invention, Figures 4 to 11 As shown, the wire controller also includes a front shell 60 and a rear cover 70, and the front shell 60 and the rear cover 70 are assembled to form a box-like structure. For example, the front shell 60 is formed with a storage space with an opening facing backward; the rear cover 70 is arranged at the opening of the front shell 60. The touch control board 20 is arranged inside the box-like structure, that is, the touch control board is arranged in the storage space. The mounting plate 32 may be a part of the front shell 60. An LCD screen is arranged on the front shell 60, and a liquid crystal screen 80 and a backlight source 90 that cooperate with the LCD screen are arranged between the LCD screen and the touch control board 20. In some alternative embodiments of the utility model, the wire controller may not have an LCD screen. In some alternative embodiments of the utility model, the wire controller may not have an LCD screen and the LCD screen is integrated together.

[0067] In some embodiments of the present invention, Figure 6 , Figure 7 As shown, since the backlight source 90 partially covers the conductive pad 21, the touch portion 30 is only arranged on the side of the backlight source 90 away from the touch control board 20. The pressing block 31 of this part of the touch portion 30 is the first pressing block 3101. There is no backlight source 90 between the pressing block 31 and the conductive pad 21 in the remaining part, and the pressing block 31 in the remaining part can be the second pressing block 3102. The height of the first pressing block 3101 is less than the height of the second pressing block 3102, which is convenient for the reasonable arrangement of the wire controller structure.

[0069] In some embodiments of the utility model, after improving the anti-interference ability on the basis of hardware design, the anti-interference ability can also be further improved in the control method, such as controlling the current noise of the wire controller to dynamically adjust the touch key effect. For example, the size of the backlight current noise of the wire controller has a great influence on the effect of the touch key. By adjusting the backlight current noise, the backlight brightness and the sensitivity and anti-interference ability of the touch key reach a dynamic balance point. For example, while meeting the backlight requirements, the noise is reduced so that the noise is outside the touch key threshold range to avoid interfering with the touch key. Further, touch value threshold training can also be performed, and a large number of training simulations are performed for each touch key to simulate a suitable threshold range, and different touch threshold ranges are provided for different touch keys. Further, a reverse touch threshold test is performed, and the threshold range obtained by training will avoid the threshold value that responds when the reverse side of the touch key is touched. In the case of anti-interference of the shielding member, the anti-interference effect is further improved by threshold setting.
