Description

Push type switch

Technical Field

The invention belongs to the technical field of vehicle control switches, and particularly relates to a push type switch.

Background

Fig. 1 and 2 show a conventional push switch in a vehicle, fig. 1 shows a conventional push switch in a vehicle in an unpressed state, and fig. 2 shows a conventional push switch in a vehicle in a pressed state, and it can be seen that the conventional push switch includes a button 101 having a conductive member 102 at a bottom thereof and a gold dot 103 of a circuit board spaced from the conductive member 102, and when the conventional push switch is in the unpressed state shown in fig. 1, the conductive member 102 is separated from the gold dot 103 of the circuit board, which means that the conventional push switch is not turned on, and when the conventional push switch is in the pressed state shown in fig. 2, the conductive member 102 is in contact with the gold dot 103 of the circuit board, which means that the conventional push switch turns on the circuit board and can perform a corresponding function.

In the prior art, most of used push type switches are hand-feeling realized by silica gel, but due to the limitation of the structure, one silica gel point only has one-gear hand-feeling, and the switch can be switched on only when the silica gel point is pressed to the bottom. However, in practical applications, different processing manners are required for different situations, for example, the switch needs to be turned on earlier in some cases, and the switch needs to be turned on later in some cases. For example, some operations which are not related to driving safety, such as volume adjustment of music, previous or next operation and the like, are more suitable for being switched on in advance, so that the problem that a user leaves a key without waiting for stable switching-on during quick operation can be prevented, the success rate of operation is improved, and some operations related to driving safety are more suitable for enabling the user to switch on after the user really has strong hand feeling, and the switching-on operation can be delayed properly at the moment to ensure that the user has a very clear operation intention, so that the driving safety can be better guaranteed. However, the prior art does not have the push type switch capable of conducting in advance or conducting in a delayed manner, so that the different types of function switches cannot be improved in a targeted manner.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of a push switch provided in the present application is shown in fig. 3, fig. 3 is a schematic structural view of a push switch provided in the present application, the push switch includes an annular key base 302 fixed on a first supporting member 301, the specific type of the first supporting member 301 is not limited, the first supporting member 301 can be a circuit board, or a base that can simply support, and is not limited herein, an inner upper portion of the key base 302 is connected to an annular key cap 304 located at the upper portion through a large skirt 303 that extends obliquely upward and toward the center, it can be seen that the large skirt 303 is relatively thin with respect to the key cap 304 and the key base 302, so that when pressed, the large skirt 303 will bend with other components to drive a key core 306 connected therewith to move downward until the key core 306 contacts with the first supporting member 301, and at this time, a first hand feeling can be generated, if the bottom surface of the key core 306 has the conductive member 308 and the first supporting member is a circuit board, the circuit can be conducted, and the state is as shown in fig. 4, fig. 4 is a schematic diagram of the first-stage pressed state of the press switch provided by the present application, and the lower portion of the inner side of the key cap 304 is connected to the key core 306 through a small skirt 305 extending obliquely downward and toward the center, and the upper portion of the key cap 304 is fixed with the second supporting member 307, and the small skirt 305 is thinner than both the key core 306 and the key cap 304, but as shown in the structure shown in fig. 3, the bending of the small skirt 305 lags behind the bending of the large skirt 303, and only when the large skirt 303 bends to the point that the key core 306 contacts with the first supporting member 301 as shown in fig. 4 and cannot move downward, the small skirt 305 will begin to bend, so that the upper surface of the key core 306 continuously approaches the second supporting member 307 until the two contact, as shown in fig. 5, fig. 5 is a schematic diagram of a second-stage pressed state of the push switch provided in the present application, which can generate a second hand feeling, if the upper surface of the key core 306 also has a conductive component and the second supporting component 307 is a circuit board, the circuit can be conducted, it should be noted that, in this embodiment, at least one of the upper surface and the lower surface of the key core 306 has a conductive component 308, since such a conductive component 308 is generally a layer that is adhered, it cannot be clearly shown in the figure, and the first supporting component 301 and/or the second supporting component 307 adjacent to the conductive component 308 are/is a circuit board for conducting the circuit when contacting with the conductive component 308, that is, the conductive component can be separately disposed on the upper surface of the key core, or the conductive component can be separately disposed on the lower surface of the key core, the upper surface and the lower surface of the key core can be simultaneously provided with the conductive parts, the supporting parts are correspondingly selected as circuit boards, the up-down stroke or force is adjusted due to twice pressing, and the conducting stroke can be controlled before the wave crest or after the wave trough of the force curve, so that the circuit can be conducted in advance or conducted in a delayed way or conducted twice, and the function setting of the key is enriched.

It should be noted that, in this embodiment, if the lower surface (large contact) of the key core 306 is made to have no feel (spring-like feel) and the conductive member 308 is located on the lower surface of the key core 306, advance of the turn-on can be achieved, that is, when the user presses such a switch, when the feel is generated, it is proved that the contact of the upper surface of the key core 306 with the second support member 307 has been achieved, and at this time, the conduction of the lower surface of the key core 306 with the circuit of the first support member 301 has been achieved, which proves that advance of the conduction has been achieved; when the large contact and the small contact have hand feelings and the circuit board is positioned at one end of the large contact, two-gear hand feelings can be realized, and the circuit board can be switched on in advance; when one of the contacts is made to have no hand feeling (similar to spring hand feeling), and the circuit board is positioned at one end of the small contact, the delay of connection can be realized.

As can be seen from the above description, in the embodiment of the push switch provided in the present application, since the push switch includes the annular key base fixed on the first supporting member, the inner upper portion of the key base is connected to the annular key cap located at the upper portion through the large skirt extending obliquely upward and toward the center, the inner lower portion of the key cap is connected to the key core through the small skirt extending obliquely downward and toward the center, the second supporting member is fixed on the upper portion of the key cap, at least one of the upper surface and the lower surface of the key core has the conductive member, and the first supporting member and/or the second supporting member adjacent to the conductive member is/are a circuit board for realizing circuit conduction when contacting the conductive member, it can be seen that when the switch is pressed, first contact between one surface of the key core and the supporting member adjacent thereto can be realized, which generates a first-stop feeling, if the press is continued, another face of button core and rather than adjacent support component contact again, this has just produced the second grade and has felt, it is therefore visible, this just can realize two grades on a switch and feel, in addition, now can have two grades to feel, just can set up and realize switching on or switch on when producing the second grade and feel when producing first grade and feel, thereby realize switching on in advance or lagging and switch on, it is more nimble to set up, can promote the success rate that user's car in-car controlled equipment under some circumstances, can also promote the security that user controlled car in-car equipment under other circumstances.

Fig. 6 is a schematic view of an embodiment of the push switch provided in the present application, in which the upper surface of the key core 306 has a conductive member 308, the first supporting member 301 is a key, and the second supporting member 307 is a circuit board, when the push switch is pressed, the lower surface of the key core 306 is firstly in contact with the first supporting member 301, and the state is as shown in fig. 7, fig. 7 is a schematic view of the first-stage pressing state of an embodiment of the push switch provided in the present application, and the upper surface of the key core 306 is not in contact with the second supporting member 307, so that the circuit is not turned on, and only the first hand feeling can be generated, when the push switch is pressed, the upper surface of the key core 306 and the second supporting member 307 approach each other until they contact, and the state is as shown in fig. 5, at the moment, the second hand feeling can be generated, and the circuit board can be conducted. Therefore, the scheme can ensure that the circuit board is not switched on when the first hand feeling is generated and is switched on only when the second hand feeling is generated, and the embodiment can realize switching-on hysteresis, so that the method is suitable for the switch which needs to ensure safety, and after all, the switch needs to be switched on by pressing, so that the user really wants to press the switch instead of pressing the switch accidentally.

It should be noted that, in the above embodiment, when the stroke of the upper structure (i.e. the small contact) of the key core 306 is greater than 0, and when both the upper and lower contacts have hand feeling, two-gear hand feeling can be realized, and when one of the contacts has no hand feeling (similar to a spring), one-gear hand feeling can be realized.

In another embodiment of the above-described push switch, as shown in fig. 3, the lower surface of the key core 306 has a conductive member 308, the first supporting member 301 is a circuit board, and the second supporting member 307 is a key, and this embodiment provides a push switch suitable for controlling a non-safety switch, such as a music switch, so that the circuit can be turned on only when a first touch is generated, which is more convenient for a user to turn on or off, and does not affect driving safety even if the user operates it carelessly, and thus this type of switch is more suitable for use.

In practice, sometimes it is necessary to use the same key to implement two-gear hand feeling, so as to implement two functions, for example, the switch of a power window, and it is necessary to implement one-key automatic lifting or manual lifting, which all needs the same key to complete, but there are two processing methods in the prior art: firstly, with two contact switches, arrange side by side, one is high, one is low, high manual, low automation, and the shortcoming has arranged two contacts, and the space demand is great, secondly only uses a contact, and the short is pressed automatically, presses manually for a long time, and the shortcoming is that the driver is difficult to master the time of pressing, easy maloperation, and it is all very inconvenient to see. In view of the above practical requirements, the present application provides another embodiment of the push switch, as shown in fig. 8, fig. 8 is a schematic diagram of another embodiment of the push switch provided in the present application, in which both the upper surface and the lower surface of the key core 306 have the conductive component 308, and both the first supporting component 301 and the second supporting component 307 are circuit boards, a first-stage pressing state of the push switch is shown in fig. 9, fig. 9 is a schematic diagram of a first-stage pressing state of another embodiment of the push switch provided in the present application, it can be seen that in the first stage, a first hand feeling is generated and a circuit under the key core 306 is connected, and a second-stage pressing state of the push switch is shown in fig. 10, fig. 10 is a schematic diagram of a second-stage pressing state of another embodiment of the push switch provided in the present application, it can be seen that in the second stage, the circuit above the key core 306 is switched on while the second hand feeling is generated, and the circuit below the key core 306 is still in a switched-on state at the moment, so that in summary, the embodiment realizes the sequential switching-on of the two circuits.

In the above embodiments of the push switch, the conductive component may be gold, silver or nickel, or a sheet of these metals, and taking gold as an example, the conductive component may be gold-plated on a copper sheet to achieve conductivity, so that the conductive component has excellent conductivity, and of course, other types of conductive components, such as carbon powder, may be selected according to actual needs, without limitation, and in addition, the push switch may be a silicon switch or a rubber switch, and both of these two materials have better elasticity, so as to facilitate bending operation, and of course, other materials may be selected according to actual needs to manufacture the push switch, without limitation.

To sum up, the above-mentioned embodiment adopts the mode of two kinds of contact structure superposes, through adjusting the power of two contacts, realizes the regulation of one grade or two grades of handfeels, through adjusting the stroke difference of two contacts, realizes advancing or lagging of conduction stroke, still through two upper and lower circuit boards mutual relative pressure, realizes that two circuit boards all switch on, also can integrate a plurality of little contacts on following one big contact, realizes the different handfeel of many grades, perhaps switches on many times.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
