Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.

The foregoing description of various embodiments of the invention is provided for the purpose of illustration to one of ordinary skill in the relevant art. It is not intended that the invention be limited to a single disclosed embodiment. As mentioned above, many alternatives and modifications of the present invention will be apparent to those skilled in the art of the above teachings. Thus, while some alternative embodiments are specifically described, other embodiments will be apparent to, or relatively easily developed by, those of ordinary skill in the art. The present invention is intended to embrace all such alternatives, modifications and variances of the present invention described herein, as well as other embodiments that fall within the spirit and scope of the present invention as described above.

The invention provides a multifunctional multiplexing switch device for a vehicle. Fig. 1 to 10 show a multi-function multiplex switch apparatus for vehicles, which is installed in a motor vehicle for user operation, according to a preferred embodiment of the present invention. The multi-function multiplexing switch device for a vehicle is a multiplexing switch, that is, a function can be selected in a plurality of (i.e., two or more) modes.

Referring first to fig. 1, the multi-functional multiplexing switching device for vehicles includes a housing 1 having an opening, a switching assembly, a light-transmitting sheet 22, a driving assembly 23, a PCB 4 integrated with an indicator lamp, and the like. Specifically, the housing 1 is a box-type housing and is formed roughly in a box-type structure of a rectangular parallelepiped, but is open at the top and bottom, and is open at the top to be formed as an opening of the housing 1, or it can be understood that the top wall of the housing 1 has an opening. The bottom of the housing 1 may be provided with a base (not shown) on which the PCB board 4 and the like may be mounted.

The switch assembly is disposed within the housing 1 and the top of the switch assembly is exposed from an opening of the housing 1 for convenient operation by a user. The switch assembly includes a mode changeover switch 21 and a plurality of function switches 3. Wherein the mode switching switch 21 is configured to be activated to implement mode switching, and the function switch 3 is located at the opening of the housing 1 and configured to implement a selected function in a selected mode. In the present embodiment, the mode switching switch 21 and the function switch 3 are each a push button 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.

Herein, the first direction D1 is a one-way direction indicated by an arrow in the figure, and if the vehicular multi-function multi-use switch device is placed on a horizontal plane, the first direction D1 is substantially equivalent to a downward vertical direction. Thus, directional terms herein such as "downward," "below," "lower side," "bottom side," "bottom surface," and the like may be understood as directions or positions upstream with respect to the first direction D1, while directional terms such as "upward," "above," "upper side," "top side," "top surface," and the like may be understood as directions or positions downstream with respect to the first direction D1. For example, referring to fig. 2, the top surface of the button can be contacted with the 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 transmissive sheet 22, the indicator lamp, and the actuator assembly 23 are collectively formed 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 transmissive sheet 22 is located inside the housing 1 and opposite the bottom surface of the switch assembly. The light-transmitting sheet 22 can move, and a plurality of identification parts 221 with different shapes are arranged on the light-transmitting sheet 22 along the moving direction of the light-transmitting sheet, and the identification parts 221 correspond to selectable modes one by one.

The driving unit 23 of the multi-functional multiplexing switch device for vehicles is connected between the mode switching switch 21 and the light transmitting sheet 22 to transmit the movement of the mode switching switch 21 to the light transmitting sheet 22, so that the light transmitting sheet 22 moves simultaneously when the modes are switched, and the light of the indicator lamp can pass through the identification part 221 corresponding to the selected mode to show the shape of the identification part 221 to the user, so that the user can visually see the operation mode at this time after pressing the mode switching switch 21. In the present embodiment, the indicator lamp is integrated on the PCB board 4.

The structure of the transmission assembly 23 in the present 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 mark part 221 illuminated by the indicator light.

More specifically, the transmission assembly 23 includes a first ram 24, a second ram 26, and a gear assembly. The first plunger 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 plunger 24 is capable of moving in the first direction D1 when the mode switch 21 is pressed in the first direction D1. The second top bar 26 is arranged in parallel with the first top bar 24 and the second top bar 26 is connected with the light-transmitting sheet 22. The gear assembly engages the first and

second rams

24 and 26, respectively, to transfer the motion of the first ram 24 to the second ram 26. The number of gears in the gear assembly can be odd or even, and it will be understood that when the number of gears is odd (e.g., only one gear is provided), the directions of movement of the first ram 24 and the second ram 26 are opposite; when the number of gears is even (for example, two gears in the present embodiment), the moving directions of the first push rod 24 and the second push rod 26 are the same.

More preferably, when the gear assembly includes a plurality of gears, the plurality of gears can be configured to have different diameters so 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 plunger 24 is smaller than the diameter of the second gear 252 engaged with the second plunger 26, so that the moving rate of the second plunger 26 is greater than the moving rate of the first plunger 24, and the displacement of the second plunger 26 is greater than the displacement of the first plunger 24 during the mode switching. Such an arrangement allows the user to press the mode switch 21 only lightly, but the movement stroke of the hollow plate can be relatively large through the speed change of the gear assembly, so as to achieve effective switching of the mark 221.

The configuration and movement pattern of the light transmissive sheet 22 may also have a variety of settings. In the present embodiment, the light-transmissive sheet 22 is made of a flexible material and is capable of moving back and forth on 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, 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 can be viewed by a user, and a portion of the light-transmitting sheet 22 located in the first and third planes is invisible to the user by being shielded by the case 1.

For convenience of description, a portion of the light-transmissive sheet 22 lying in a first plane is referred to as a first portion 225, a portion of the light-transmissive sheet 22 lying in a second plane is referred to as a second portion 226, and a portion of the light-transmissive sheet 22 lying in a third plane is referred to as a third portion 227, as particularly shown in fig. 4. It will be appreciated that the first section 225, the second section 226 and the third section 227 are not fixed because the light transmissive sheet 22 is movable.

Also, defining a third direction D3 perpendicular to both the first direction D1 and the second direction D2, preferably, the first portion 225 and the third portion 227 are both located at the lower side of the second portion 226, that is, the extending directions of the light-transmitting sheets 22 on the first plane and the third plane are 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-enclosed structure, similar to three sequentially connected sides of a rectangle. To achieve this, the lower side of the light-transmissive sheet 22 supports two support bars 27, and the two support bars 27 are spaced apart from each other by a predetermined distance such that the light-transmissive sheet 22 changes its moving direction around it so that the light-transmissive sheet 22 can move back and forth on three planes connected in series.

In other embodiments, not shown, the light transmissive sheet 22 may be disposed such that the first and third portions may be staggered in the third direction D3, i.e., the first and third portions extend in opposite directions (i.e., the light transmissive sheet extends in opposite directions in the first and third planes), such that the first, second and third portions collectively form a Z-shaped structure in side view, for example. To realize such a structure, one support bar 27 is supported on the upper side of the light-transmitting sheet 22 and one on the lower side of the light-transmitting sheet 22, and the light-transmitting sheet 22 changes the moving direction at the support bar 27 by the supporting action of the support bar 27 to form a Z-shaped structure.

In addition, it should be further emphasized that, herein, as shown by the arrow in the drawings, the first direction D1 is a unidirectional direction; and the second direction D2 and the third direction D3 are bidirectional directions, unlike the first direction D1.

Three groups of identification parts 221 are correspondingly arranged on the light-transmitting sheet 22, and the identification parts 221 respectively form marks: MEF, MAB and MCD. In fig. 8, the indicia on the second portion of the light transmissive sheet 22 are MEFs, where the MEFs are visible to the user, 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 to be observed by the user, and the state at this time is shown in fig. 9.

Preferably, the identification part 221 may be a hollow structure, so that light of the indicator light can directly penetrate through the identification part 221; alternatively, the mark 221 and other portions of the light-transmitting sheet 22 may be painted or colored with different colors, such that the mark 221 is different from the other portions, for example, the mark 221 may be light color and the other portions may be dark color, so that the light of the indicator can be observed through the mark. 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 contact the PCB board 4.

To allow a user to view the indicia displayed 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 displayed on the light transmissive sheet through the buttons (as will be described in more 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. Since the identifier corresponding to the lower part of the mode switch 21 is always displayed as "M", the mode switch 21 may be irradiated with "M" characters (or with no characters as shown in the drawings), and the two function switches 3 may not be irradiated with any characters.

In order to make the second push rod 26 conveniently drive the light-transmitting piece 22 to move, a stress bulge 223 is arranged at the end part of the third part of the light-transmitting piece 22, and the second push rod 26 can press the stress bulge 223 to drive the light-transmitting piece 22 to move. In order to make the light-transmitting sheet 22 move smoothly and be uniformly stressed, the point of application of the force to the force-receiving protrusion 223 by the second plunger 26 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 disappears (for example, when the user's hand leaves the mode switch 21), the transmission assembly 23 and the light-transmitting piece 22 can be restored to the original position by the restoring elastic means. In the present embodiment, the return elastic means may include a spring 5 connected to the first portion of the light-transmitting plate 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 with a substantially fixed position is further disposed on the inner wall of the housing 1, and a protrusion portion engaged with the elastic fixing block 29 is disposed on the first push rod 24. The number of the projections may be set as desired, for example, in the present embodiment, in order to display three signs in cooperation, the number of the projections is set to two. When the first push rod 24 reaches a preset position, the elastic fixing block 29 can be clamped with the corresponding bulge part to fix the first push rod 24, so that the light-transmitting piece 22 is fixed at the preset position.

For convenience of description, the projection away from the mode switching switch 21 is referred to as a first projection 241a, and the other projection is referred to as a second projection 241 b. 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 jack 24; when the user presses the mode switching switch 21 once, the first plunger 24 moves downward, in which the return elastic means is biased, which has a biasing force to bias the light-transmitting plate 22 and the driving assembly 23 toward the original position shown in fig. 8, and if the elastic fixing block 29 is engaged with the first protrusion 241a, the first plunger 24 is fixed thereto, and other components of the driving assembly 23 and the light-transmitting plate 22 are fixed accordingly; after the user presses the mode switch 21 again, the first push rod 24 moves further downward, the elastic fixing block 29 may be engaged with the second protrusion 241b to fix the first push rod 24, or the elastic fixing block 29 may return to the original position relative to the first push rod 24 for the next operation.

Referring to fig. 6, the process of returning the elastic fixing block 29 and the first jack 24 with respect to each other will be described in detail. The first push rod 24 is provided with a sliding groove 243 extending along a straight line in the first direction D1, 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 push rod 24 can slide freely relative to the elastic fixing block 29 to realize the homing. In order to guide the elastic fixing block 29 into the sliding groove 243, a guide slope facing the sliding groove 243 is further provided above the second protrusion 241 b. When the elastic fixing block 29 has been positioned above the second protrusion 241b, the mode switching switch 21 is pressed again, and the guide slope can guide the elastic fixing block 29 into the sliding 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 push rod 24, and at this time, the transmission assembly 23 and the light-transmitting piece 22 both return to the initial position for the user to operate again.

As described at the beginning of the present embodiment, mode switching can be realized by activating the mode switching switch 21. Specifically, mode switching is achieved by contact of a trigger protrusion 244 provided on the first ram 24 with the corresponding travel insert 28. The stroke inserts 28 are fixedly disposed in the housing 1 and connected to the PCB 4 through wires or wirelessly, and the trigger protrusions 244 are also made of metal, and when they contact the corresponding stroke inserts 28, output analog signals through resistors on the PCB 4 to the MCU on the PCB 4, thereby realizing mode switching. While this is being done, the second plunger 26 simultaneously moves the light transmissive sheet 22 to a predetermined position.

For example, the multifunctional multiplexing switch device for a vehicle may be set such that the "MAB" flag corresponds to the volume adjustment mode, the mode switch 21 is pressed to make the transparent sheet 22 externally display the "MAB" flag, at this time, the trigger protrusion 244 on the first plunger 24 contacts with the corresponding stroke insert 28 to make the PCB 4 select the mode as the volume adjustment mode, and at this time, the volume can be increased or decreased by pressing the function switch 3; for another example, the multi-function multiplexing switch device for vehicle can be set such that the "MCD" flag corresponds to the fast forward/fast backward mode, such as when playing an audio file in a CD, pressing the mode switch 21 to make the transparent sheet 22 show "MCD" outward, and then the trigger protrusion 244 on the first plunger 24 contacts with the corresponding stroke insert 28 to make the PCB 4 select the mode as the fast forward/fast backward mode, and then pressing the function switch 3 can realize fast forward or fast backward during audio playing.

The multifunctional multiplexing switch device for the vehicle CAN select a CAN communication mode or a LIN communication mode. Each function switch CAN correspond to two different CAN or LIN values, the function switch is triggered in a certain mode, the selected mode is judged, and then the corresponding CAN or LIN signal is output. For example, as shown in fig. 7, after receiving the input of the mode switch, the switch MCU will change the output signal to realize the multiplexing function.

It is to be understood that the multi-function multiplexing switch device for vehicle in the present embodiment can realize function selection in three modes, but in other embodiments not shown, the multi-function multiplexing switch device for vehicle can select functions in three or more modes, respectively. In order to correspond to a plurality of modes, the size of the first ejector rod in the first direction can be increased, the number of the stroke inserts is increased, the number of the mark parts on the light-transmitting sheet is correspondingly increased, and the size of the light-transmitting sheet in the moving direction is also correspondingly increased.

Fig. 11 to 13 show a partial structure of another embodiment according to the present invention, in which the vehicular multi-function multiplexing switching device can select only two modes, and accordingly, a second-order switch 6 may be used instead of a stroke insert to realize mode selection.

In particular, the second-order switch 6 comprises a T-shaped jack 61 and two microswitches. The T-shaped push rod 61 comprises a force bearing end 311 and two force applying ends, the force applying end is located at the upstream of the force bearing end 311 in the first direction D1, the mode switching switch can press the force bearing end 311 of the T-shaped push rod 61 in the first direction D1, and the two micro switches are respectively located at one side of the two force applying ends in the first direction D1. And, the distances of the two force applying ends from the force receiving end 311 in the direction perpendicular to the first direction D1 are not equal. For convenience of description, a force application end closer to the force receiving end 311 in a direction perpendicular to the first direction D1 is referred to as a first force application end 612, and a corresponding micro switch is referred to as a first micro switch 62; the other force-bearing end 311 and the corresponding microswitch are referred to as second force-bearing end 311 and second microswitch 63, respectively.

Then, a force is applied to the force-bearing end 311 of the T-shaped push rod 61 along the first direction D1, and the force-applying end will correspondingly trigger the micro switch. In order to trigger the two microswitches successively, a structure similar to a fulcrum may be disposed on the upstream side of the T-shaped push rod 61 in the first direction D1, or a mechanism may be disposed to slightly change the force application direction so that the direction of the force applied to the force-receiving end 311 is slightly shifted toward the first force-applying end 612 relative to the first direction D1, so that the first force-applying end 612 contacts the first microswitch 62 first (as shown in fig. 12), and the second force-applying end contacts the second microswitch 63 when the mode switch is continuously pressed (as shown in fig. 13). Only the first microswitch 62 being activated corresponds to one mode, while both the first microswitch 62 and the second microswitch 63 being activated correspond to the other mode.

Fig. 14 shows a schematic structural view of a part of a component of yet another preferred embodiment of the present invention. In this embodiment, the mode switch may include a knob that may correspondingly operate electronic devices such as an air conditioner, entertainment control, and the like. The transmission assembly may include a worm gear assembly 7. The worm gear assembly 7 comprises a worm 71 engaged with the knob and a worm wheel 72 connected to the light transmissive sheet, the worm gear assembly 7 being capable of transferring rotational movement of the knob to the light transmissive sheet to move the light transmissive sheet and display a selected mode while switching modes.
