Description

Technical Field

[0001] The invention relates to a push button structure and an electric seat, belonging to the technical field of push button structures. Background Art

[0002] In automobile central control, electric seat adjustment control, audio, home appliances and other electronic products, push button structures are needed to achieve up and down or left and right action responses.

[0003] Most of the current push button structures are mechanical structures, which cannot be completely dustproof and waterproof. Although capacitive touch has the effect of dustproof and waterproof, it only has a pressing function and cannot achieve action response in multiple directions such as up and down or left and right.

[0004] It can be seen that in order to solve the above technical problems, a push button structure and an electric seat are urgently needed. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a push button structure and an electric seat. The MCU controls the execution end to perform different actions based on the difference in the received signal strength, so as to achieve different action responses by touching different non-conductive layers. At the same time, the integrated setting of the conductive layer and the non-conductive layer has the advantages of dustproof and waterproof compared to the existing mechanical push buttons.

[0006] In order to achieve the above purpose / solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0007] In a first aspect, the present invention provides a push button structure, comprising a conductive layer and non-conductive layers disposed on upper and lower sides of the conductive layer, wherein:

[0008] The conductive layer and the non-conductive layer are integrally arranged;

[0009] The ratio of the thickness d1 of the non-conductive layer on one side of the conductive layer to the thickness d2 of the non-conductive layer on the other side is d1 / d2>4;

[0010] The conductive layer is used to cooperate with the touch IC. When one side of the non-conductive layer away from the conductive layer is touched, the touch IC transmits a signal to the MCU. The MCU controls the execution end to execute action one or action two based on the strength of the received signal.

[0011] Furthermore, the non-conductive layer is made of plastic.

[0012] Furthermore, the conductive layer is made of metal.

[0013] Furthermore, the non-conductive layer is injection-molded on the outer side of the conductive layer.

[0014] Furthermore, d1=2.25mm, d2=0.25mm.

[0015] Furthermore, the conductive layer is wrapped between the non-conductive layers, and the conductive layer is not exposed.

[0016] In a second aspect, the present invention provides an electric seat, comprising the push button structure described in the first aspect, wherein there are multiple push button structures, and the multiple push button structures are used to realize multi-directional movement of the electric seat.

[0017] Furthermore, there are two push button structures. When one side of the non-conductive layer of one of the push button structures is touched, the electric seat moves up / down, and when one side of the non-conductive layer of the other push button structure is touched, the electric seat moves left / right.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the push button structure provided by the present invention, the MCU controls the execution end to perform different actions based on the difference in the received signal strength, so as to achieve different action responses by touching different non-conductive layers. At the same time, the integrated arrangement of the conductive layer and the non-conductive layer has the advantages of dustproof and waterproof compared with the existing mechanical push button.

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] Embodiment 1:

[0035] like Figure 1-9 As shown, this embodiment provides a push button structure, including a conductive layer 1 and a non-conductive layer 2 arranged on the upper and lower sides of the conductive layer 1, wherein:

[0036] The conductive layer 1 and the non-conductive layer 2 are integrally arranged;

[0037] The ratio d1 / d2 of the thickness d1 of the non-conductive layer 2 on one side of the conductive layer 1 to the thickness d2 of the non-conductive layer 2 on the other side is greater than 4;

[0038] The conductive layer 1 is used to cooperate with the touch IC. When one side of the non-conductive layers 2 away from the conductive layer 1 is touched, the touch IC transmits a signal to the MCU. The MCU controls the execution end to execute action one or action two based on the strength of the received signal.

[0039] When d1 / d2>4, the intensity of the detected signal is much less affected by the touch area than by the thickness. The experimental results are as follows: Figure 3-7 As shown, Figure 3 and Figure 4 The signal strength detected under different touch areas of the thicker non-conductive layer 2 is shown. Figure 5 and Figure 6 The figure shows the signal strength detected under different touch areas of the thinner non-conductive layer 2. Figure 7 This is the detection result comparison chart. Figure 7 1, 2, 3, and 4 represent the two detection results of the thicker non-conductive layer 2 and the two detection results of the thinner non-conductive layer 2 respectively. It can be seen that the two detection results of the thicker non-conductive layer 2 always fall within the range of lower signal strength, and the two detection results of the thinner non-conductive layer 2 always fall within the range of higher signal strength.

[0040] In the above technical solution, since the thickness of the two non-conductive layers 2 is different, through C=ε r A / d, achieving the signal difference on the two sides, that is, the signal strength received by the MCU is different. Based on this, the MCU controls the execution end to perform different actions to achieve different action responses by touching different non-conductive layers 2. At the same time, the integrated setting of the conductive layer 1 and the non-conductive layer 2 has the advantages of dustproof and waterproof.

[0041] Compared with the existing mechanical push button, the push button structure is not restricted in shape and can achieve more varied appearances, such as Figure 8 and Fig. 9 shown.

[0042] In some embodiments, in order to meet the non-conductive property of the non-conductive layer 2, the non-conductive layer 2 is made of plastic, but is not limited thereto. The non-conductive layer 2 can also be made of other materials as long as it can meet the non-conductive property of the non-conductive layer 2, such as glass, ceramic, etc.

[0043] In some embodiments, to meet the conductivity of the conductive layer 1, the conductive layer 1 is made of metal, but not limited thereto. The conductive layer 1 can also be made of other materials as long as the conductivity of the conductive layer 1 can be met, such as ITO, transparent conductive film, etc.

[0044] In some embodiments, in order to realize the integrated arrangement of the non-conductive layer 2 and the conductive layer 1 , the non-conductive layer 2 is injection molded on the outer side of the conductive layer 1 .

[0045] In some embodiments, d1=2.25mm, d2=0.25mm, satisfying d1 / d2>4.

[0046] In some embodiments, in order to further enhance the dustproof and waterproof effect of the push button, the conductive layer 1 is wrapped between the non-conductive layers 2, and the conductive layer 1 is not exposed.

[0047] To sum up, in the push button structure provided in this embodiment, the MCU controls the execution end to perform different actions based on the difference in the received signal strength, so as to achieve different action responses by touching different non-conductive layers 2. At the same time, the integrated setting of the conductive layer 1 and the non-conductive layer 2 has the advantages of dustproof and waterproof compared to the existing mechanical push buttons.

[0048] Embodiment 2:

[0049] This embodiment provides an electric seat, including the push button structure described in the first embodiment, wherein there are multiple push button structures, and the multiple push button structures are used to realize multi-directional movement of the electric seat.

[0050] It is worth mentioning that the push button structure can also be applied to automobile central control, audio, home appliances and other electronic products, and can be adjusted according to specific needs during application.

[0051] In some embodiments, Fig. 9 As shown, there are two push button structures. When one side of the non-conductive layer 2 of one of the push button structures is touched, the electric seat moves up / down, and when one side of the non-conductive layer 2 of the other push button structure is touched, the electric seat moves left / right; but not limited to this, the number of push button structures can also be adjusted according to specific needs to achieve adjustment of the electric seat in more directions.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
