Detailed Description
Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment according to the present invention, and other ways of implementing the invention will occur to those skilled in the art on the basis of the preferred embodiment, and are intended to fall within the scope of the invention as well.
The foregoing description of various embodiments of the invention has been presented for the purpose of illustration to one of ordinary skill in the relevant art. It is not intended that the invention be limited to the exact embodiment disclosed or as illustrated. As described above, many alternatives and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the above teachings. Thus, while some alternative embodiments have been specifically described, those of ordinary skill in the art will understand or relatively easily develop other embodiments. The present invention is intended to embrace all alternatives, modifications and variations of the present invention described herein and other embodiments that fall within the spirit and scope of the invention described above.
The invention provides a multifunctional multiplexing switch device for a vehicle. Fig. 1 to 10 show a multifunctional multiplex switching device for vehicles installed in a motor vehicle for user operation according to a preferred embodiment of the present invention. The multifunctional multiplexing switch device for a vehicle is a multiplexing switch, that is, the function selection can be performed in a plurality of (i.e., two or more) modes, and in this embodiment, the multifunctional multiplexing switch device for a vehicle can realize the function selection in three modes.
Referring first to fig. 1, the multifunctional multiplexing switch device for a vehicle includes a case 1 having an opening, a switch assembly, a light-transmitting sheet 22, a transmission assembly 23, a PCB board 4 integrated with an indication lamp, and other components. Specifically, the housing 1 is a box-type housing and is formed substantially as a box-type structure of a rectangular parallelepiped, but is open at the top and bottom, and is open at the top to form an opening of the housing 1, or it can be understood that the top wall of the housing 1 has an opening. A base (not shown) may be provided at the bottom of the housing 1, and the PCB 4 or the like may be mounted on the base or the housing.
The switch assembly is disposed in the housing 1 and the top of the switch assembly is exposed from the opening of the housing 1 to facilitate the operation of a user. The switch assembly comprises a mode changeover switch 21 and a plurality of function switches 3. Wherein the mode switch 21 is configured to be triggered to effect mode switching, and the function switch 3 is located at the opening of the housing 1 and is configured to be able to effect a selected function in a selected mode. In the present embodiment, the mode changeover switch 21 and the function switch 3 are both buttons that can be pressed in the first direction D1, and the function switch 3 has a trigger lever that extends toward the PCB board 4 in the first direction D1, and the trigger lever can trigger a micro switch on the PCB board 4 when the function switch 3 is pressed.
Here, the first direction D1 is a unidirectional direction indicated by an arrow in the drawing, and if the multifunctional multiplexing switch device for a vehicle is placed on a horizontal plane, the first direction D1 is substantially equivalent to a downward vertical direction. Thus, the directional terms "downward", "below", "underside", "bottom surface" and the like herein may be understood as being an upstream direction or position relative to the first direction D1, while terms such as "upward", "above", "upper", "top", "topside", "top side", and the like may be understood as being a downstream direction or position relative to the first direction D1. For example, referring to fig. 2, the top surface of the button can be contacted by a user's hand so that the button is pressed while the bottom surface of the button faces the light transmitting sheet 22.
In the present embodiment, the mode switching switch 21, the light transmitting sheet 22, the indicator lamp, and the transmission assembly 23 are formed together as the mode switching assembly 2, and the mode switching assembly 2 of the present embodiment will be described in detail with reference to fig. 1 to 10. The light transmitting sheet 22 is located inside the housing 1 and opposite to the bottom surface of the switch assembly. The light-transmitting sheet 22 is movable, and a plurality of identification parts 221 with different shapes are arranged on the light-transmitting sheet 22 along the moving direction, and the identification parts 221 are in one-to-one correspondence with the selectable modes.
The transmission assembly 23 of the multifunctional multiplexing switch device for vehicles is connected between the mode switch 21 and the light-transmitting sheet 22 to transmit the movement of the mode switch 21 to the light-transmitting sheet 22, so that the light-transmitting sheet 22 moves simultaneously when the modes are switched, the light of the indicator light can pass through the identification part 221 corresponding to the selected mode, the shape of the identification part 221 is displayed to a user, and the user can intuitively see the operation mode at the moment after pressing the mode switch 21. In this embodiment, the indicator light is integrated on the PCB board 4.
The structure of the transmission assembly 23 in this embodiment is shown in fig. 5. Specifically, the transmission assembly 23 is located within the housing 1 and is associated with the mode switch 21 and the light transmissive sheet 22, respectively. When the mode switch 21 is triggered, the transmission assembly 23 can drive the light transmitting sheet 22 to move to a predetermined position, so that the user can observe the corresponding identification portion 221 illuminated by the indicator light.
More specifically, the transmission assembly 23 includes a first carrier bar 24, a second carrier bar 26, and a gear assembly. The first jack 24 is located upstream of the mode switch 21 in the first direction D1 (i.e., below the mode switch 21 as shown), and the first jack 24 is movable along with the first direction D1 when the mode switch 21 is pressed in the first direction D1. The second push rod 26 is arranged in parallel with the first push rod 24, and the second push rod 26 is connected with the light-transmitting sheet 22. The gear assembly engages the first and second rams 24, 26, respectively, to transfer movement of the first ram 24 to the second ram 26. The number of gears in the gear assembly may be odd or even, it being understood that when the number of gears is odd (e.g., only one gear is provided), the direction of movement of the first and second rams 24, 26 is opposite; when the number of gears is even (for example, two gears in the present embodiment), the movement directions of the first jack 24 and the second jack 26 are the same.
More preferably, when the gear assembly includes a plurality of gears, the plurality of gears may be configured to have different diameters such that the second ram 26 has a different rate of movement than the first ram 24. For example, in the present embodiment, the diameter of the first gear engaged with the first jack 24 is smaller than the diameter of the second gear 252 engaged with the second jack 26, so that the movement rate of the second jack 26 is greater than that of the first jack 24, and the displacement of the second jack 26 during the mode switching is greater than that of the first jack 24. The arrangement can enable the user to press the mode switch 21 only lightly, but the movement stroke of the hollowed-out piece can be larger finally through the speed change of the gear assembly, so that the effective switching of the identification part 221 is realized.
The configuration and movement pattern of the light-transmitting sheet 22 may also have a variety of settings. In the present embodiment, the light-transmitting sheet 22 is made of a flexible material and is movable to and fro in three planes, which are a first plane, a second plane, and a third plane in this order. Wherein the second plane is perpendicular to the first direction D1, and the first and third planes are parallel to the first direction D1 with a predetermined distance therebetween, a portion of the light-transmitting sheet 22 located in the second plane faces the button and is visible to the user, and a portion of the light-transmitting sheet 22 located in the first and third planes is invisible to the user due to being blocked by the case 1.
For convenience of description, the portion of the light transmitting sheet 22 lying in the first plane is referred to as a first portion 225, the portion of the light transmitting sheet 22 lying in the second plane is referred to as a second portion 226, and the portion of the light transmitting sheet 22 lying in the third plane is referred to as a third portion 227, as particularly shown in fig. 4. It will be appreciated that since the light transmissive sheet 22 is movable, the first portion 225, the second portion 226, and the third portion 227 are not fixed.
And, a third direction D3 is defined which is perpendicular to both the first direction D1 and the second direction D2, preferably, both the first portion 225 and the third portion 227 are located at the lower side of the second portion 226, that is, the extending direction of the light transmitting sheet 22 in the first plane and the third plane is the same. Thus, the first portion 225 and the third portion 227 face each other in the third direction D3, so that the first portion 225, the second portion 226, and the third portion 227 form a half-surrounding structure, resembling three sequentially connected sides of a rectangle. To achieve this structure, the lower side of the light-transmitting sheet 22 is supported with two support bars 27 spaced apart by a predetermined distance such that the light-transmitting sheet 22 changes its moving direction around so that the light-transmitting sheet 22 can move back and forth on three planes connected in sequence.
In other embodiments not shown, the light-transmitting sheet 22 may be arranged such that the first and third portions may be staggered in the third direction D3, i.e., the directions of extension of the first and third portions are opposite (i.e., the directions of extension of the light-transmitting sheet in the first and third planes are opposite), for example, so that the first, second and third portions together form a Z-shaped structure in side view. In order to achieve this structure, one support bar 27 is supported on the upper side of the light-transmitting sheet 22 and one is supported on the lower side of the light-transmitting sheet 22, and the light-transmitting sheet 22 changes its moving direction at the support bar 27 due to the supporting action of the support bar 27 to form a Z-shaped structure.
In addition, it should be further emphasized that, in this context, the first direction D1 is a unidirectional direction, as indicated by the arrow in the drawing; and the second direction D2 and the third direction D3 are bidirectional directions, unlike the first direction D1.
Three sets of marks 221 are correspondingly arranged on the light-transmitting sheet 22, and marks are respectively formed by the marks 221: MEF, MAB and MCD. In fig. 8, the indicia on the second portion of the light transmissive sheet 22 is the MEF, at which point the user can see the MEF, knowing that the selected mode is the mode corresponding to the MEF; when the user presses the mode changeover switch 21 once, the flag MEF moves to the third portion, and the flag MAB moves to the second portion so as to be observed by the user, the state at this time being shown in fig. 9.
Preferably, the marking part 221 may be in a hollow structure, so that the light of the indicator light can directly penetrate through the marking part 221; alternatively, the marking portion 221 and other portions of the light-transmitting sheet 22 may be respectively painted or toner-treated so that the color of the marking portion 221 is different from the color of the other portions, for example, the color of the marking portion 221 may be set to be light, and the color of the other portions may be set to be dark, so that the light of the indicator lamp can be observed through the marking portion. More preferably, the light-transmitting sheet 22 is hollowed out with a gap portion 224 extending in the moving direction of the light-transmitting sheet 22, and the trigger lever of the function switch 3 can extend downward through the gap portion 224 to be in contact with the PCB board 4.
In order to allow a user to view the indicia presented by the light transmissive sheet 22 through the buttons, the buttons are made of an at least partially transparent material so that the user can see the characters presented on the light transmissive sheet through the buttons (as will be described in detail below). For example, the button may be made of a material such as transparent PC or PMMA, and the bottom of the button may be painted, but the button after painting still needs to be transparent to light. Since the mark portion corresponding to the lower side of the mode switch 21 is always displayed as "M", the laser "M" character on the mode switch 21 (or any character may not be laser as shown in the drawing) may be used, and no character may be laser on both the function switches 3.
In order to enable the second ejector 26 to conveniently drive the light transmitting sheet 22 to move, a force-bearing protrusion 223 is arranged at the end part of the third part of the light transmitting sheet 22, and the second ejector 26 can press the force-bearing protrusion 223 to drive the light transmitting sheet 22 to move. In order to make the movement of the light-transmitting sheet 22 smooth and the stress uniform, the point of application of the second jack 26 to the stress protrusion 223 may be set at the center position of the light-transmitting sheet 22 in the second direction D2.
Preferably, the transmission assembly 23 and/or the light-transmitting sheet 22 are provided with return elastic means. When the external force acting on the transmission assembly 23 is removed (e.g. when the user's hand leaves the mode switch 21), the transmission assembly 23 and the light-transmitting sheet 22 can be returned to their original positions by the return elastic means. In the present embodiment, the return elastic means may include a spring 5 attached to the first portion of the light-transmitting sheet 22 and a second gear 252 provided as an elastic return gear.
Further, in order to fix the light transmitting sheet 22 and the transmission assembly 23 at a predetermined position, an elastic fixing block 29 is further provided on the inner wall of the housing 1, and a protruding portion is provided on the first ejector 24, which is engaged with the elastic fixing block 29. The number of the protruding portions may be set as needed, for example, in the present embodiment, in order to cooperatively display three marks, the number of the protruding portions is set to two. When the first push rod 24 reaches a predetermined position, the elastic fixing block 29 can be engaged with the corresponding convex portion to fix the first push rod 24, thereby fixing the light transmitting sheet 22 at the predetermined position.
For convenience of description, a boss distant from the mode switching switch 21 is referred to as a first boss 241a, and another boss is referred to as a second boss 241b. As can be seen from fig. 8 to 10, when the light-transmitting sheet 22 and the transmission assembly 23 are in the initial position (as shown in fig. 8), the elastic fixing block 29 is not in contact with the protruding portion of the first ejector pin 24; when the user presses the mode switch 21 once, the first push rod 24 moves downward, during which the return elastic means is biased with a biasing force biasing the light-transmitting sheet 22 and the transmission assembly 23 toward the original position shown in fig. 8, and if the elastic fixing block 29 is engaged with the first boss 241a, the first push rod 24 is fixed there, and other parts of the transmission assembly 23 and the light-transmitting sheet 22 are also fixed therewith; after the user presses the mode switch 21 again, the first ejector 24 moves further downward, and the elastic fixing block 29 may be engaged with the second protrusion 241b to fix the first ejector 24, or the elastic fixing block 29 may be restored to the original position relative to the first ejector 24 for the next operation.
The following describes in detail the homing process of the elastic fixing block 29 and the first jack 24 with respect to each other with reference to fig. 6. The first ejector rod 24 is provided with a sliding groove 243 extending along a straight line where the first direction D1 is located, and when the elastic fixing block 29 is located in the sliding groove 243, the elastic fixing block 29 does not interfere with the protruding portion, so that the first ejector rod 24 can freely slide relative to the elastic fixing block 29 to achieve homing. In order to guide the elastic fixing block 29 into the sliding groove 243, a guide slope facing the sliding groove 243 is also provided above the second boss 241b. When the elastic fixing block 29 has been positioned above the second boss 241b, the mode switch 21 is pressed again, and the guide slope can guide the elastic fixing block 29 into the slide groove 243. Thus, when the protruding portion is engaged with the elastic fixing block 29, the mode switch 21 is pressed again, the elastic fixing block 29 can enter the sliding groove 243 and slide to the initial position relative to the first ejector rod 24, and at this time, the transmission assembly 23 and the light-transmitting sheet 22 are restored to the initial positions for the user to operate again.
As described initially in this embodiment, mode switching can be achieved by triggering the mode switching switch 21. In particular, the mode switching is achieved by the contact of the trigger projections 244 provided on the first plunger 24 with the corresponding travel inserts 28. The stroke inserts 28 are fixedly arranged in the shell 1 and are connected to the PCB 4 through wires or in a wireless mode, the trigger protrusions 244 are also made of metal, and when the trigger protrusions contact the corresponding stroke inserts 28, analog signals are output to the MCU on the PCB 4 through resistors on the PCB 4, so that mode switching is realized. At the same time as this process is performed, the second jack 26 simultaneously moves the light transmitting sheet 22 to a predetermined position.
For example, the multifunctional multiplexing switch device for the vehicle may be set to enable the "MAB" mark to correspond to the volume adjustment mode, and pressing the mode switch 21 causes the transparent sheet 22 to be displayed as the "MAB" mark, at this time, the trigger protrusion 244 on the first ejector rod 24 contacts with the corresponding stroke insert 28 to enable the PCB board 4 to select the mode as the volume adjustment mode, at this time, pressing the function switch 3 can realize the increase or decrease of the volume; for another example, the multifunctional multiplexing switch device for a vehicle may be set such that the "MCD" flag corresponds to the fast forward and fast backward mode, such as when playing an audio file in a CD, pressing the mode switch 21 causes the light-transmitting sheet 22 to be displayed as "MCD" outwards, where the trigger protrusion 244 on the first ejector 24 contacts the corresponding travel insert 28 to make the PCB board 4 select the mode as the fast forward and fast backward mode, and at this time, pressing the function switch 3 can implement fast forward or fast backward during audio playing.

For example, as shown in fig. 7, after receiving the input of the mode switch, the switch MCU changes the output signal to realize the multiplexing function.
It is to be understood that the multifunctional multiplexing switch device for a vehicle in the present embodiment can realize function selection in three modes, but in other not-shown embodiments, the multifunctional multiplexing switch device for a vehicle can respectively perform function selection in three or more modes. In order to correspond to the plurality of modes, the first ejector rod may be increased in size in the first direction while increasing the number of stroke inserts, and the number of the identification portions on the light transmitting sheet is correspondingly increased while correspondingly increasing the size of the light transmitting sheet in the moving direction thereof.
Fig. 11 to 13 show a partial structure according to another embodiment of the present invention, in which the multifunctional multiplexing switch device for vehicles can select only between two modes, and accordingly, a second-order switch 6 can be used instead of a stroke insert to achieve mode selection.
Specifically, the second-order switch 6 includes a T-shaped jack 61 and two micro switches. The T-shaped ejector 61 includes a force receiving end 311 and two force application ends, the force application ends are located upstream of the force receiving end 311 in the first direction D1, the mode switch can press the force receiving end 311 of the T-shaped ejector 61 along the first direction D1, and the two microswitches are located on one side of the two force application ends in the first direction D1. Also, the two urging ends are not equidistant from the force receiving end 311 in the direction perpendicular to the first direction D1. For convenience of description, the force application end closer to the force receiving end 311 in the direction perpendicular to the first direction D1 is referred to as a first force application end 612, and the corresponding micro switch is referred to as a first micro switch 62; the other stress end 311 and the corresponding micro switch are referred to as a second stress end 311 and a second micro switch 63, respectively.
Then, the force-receiving end 311 of the T-shaped ejector rod 61 applies a force along the first direction D1, and the force-receiving end correspondingly triggers the micro switch. In order to trigger the two micro switches successively, a structure similar to a fulcrum may be disposed on the upstream side of the T-shaped ejector 61 in the first direction D1, or a mechanism may be disposed to slightly change the direction of the force applied by the force-receiving end 311 to slightly shift the direction of the force applied by the force-receiving end 311 toward the first force-applying end 612 relative to the first direction D1, so that the first force-applying end 612 contacts the first micro switch 62 (as shown in fig. 12) first, and the second force-applying end contacts the second micro switch 63 (as shown in fig. 13) when the mode switch is continuously pressed. Only the first micro-switch 62 is triggered corresponding to one mode, while both the first micro-switch 62 and the second micro-switch 63 are triggered corresponding to the other mode.
