Referring to fig. 1 and fig. 3A, the human-machine interface device 20 of the present embodiment includes a human-machine interface module 210, a fixing frame 220 and a sliding unit 230, wherein the sliding unit 230 is coupled to the fixing frame 220 and the human-machine interface module 210.
In the present embodiment, the fixing frame 220 is locked to the frame 32, but in other embodiments, the fixing frame 220 may be fixed to the frame 32 by welding, riveting, or clamping, and the like, which is not limited thereto. In the embodiment, the fixing frame 220 is formed by two matching components of the first fixing frame 2201 and the second fixing frame 2202, but in other embodiments, the number of the components forming the fixing frame 220 may be one or more than three, as long as the fixing frame 220 can be fixed with the rack 32 of fig. 1, which all fall within the protection scope of the present invention.
As shown in FIG. 1, the human-machine interface module 210 has a display unit 212 and an input unit 214 that can be flipped over. In this embodiment, the display unit 212 and the input unit 214 can be moved towards the outside of the cabinet 30 relative to the switch 10 respectively or simultaneously according to the user's requirement. Here, the display unit 212 is a screen, and the input unit 214 is a keyboard, but not limited thereto. It is noted that the human-machine interface module 210 of the present embodiment may be only the display unit 212 or a combination of the display unit 212 and the input unit 214.
As shown in fig. 3A, the sliding unit 230 of the present embodiment includes a sliding rail set 231, and the sliding rail set 231 is slidably connected to the fixing frame 220. Specifically, the slide rail set 231 includes a first slide rail 2311, a second slide rail 2312 and a third slide rail 2313 slidably connected to each other. In this embodiment, the first slide rail 2311 includes a first slide rail 2311X, a second slide rail 2311Y and a third slide rail 2311Z, the first slide rail 2311X is slidably connected to the fixing frame 220, and the second slide rail 2311Y and the third slide rail 2311Z are respectively fixed on the first slide rail 2311X. The second slide rail 2312 and the third slide rail 2313 are slidably connected to the second sub slide rail 2311Y and the third sub slide rail 2311Z of the first slide rail 2311, respectively. The second slide rail 2312 and the third slide rail 2313 are respectively fixedly connected with the display unit 212 and the input unit 214 of fig. 2. That is, the hmi module 210 of fig. 2 is connected to the sliding rail set 231 and can move between a storage position shown in fig. 1 and an operation position shown in fig. 3G relative to the fixing frame 220.
In the present embodiment, the hmi device 20 further includes an elastic member 240 and a linking member 250. The two ends of the elastic element 240 of the present embodiment are respectively fixed to the sliding rail set 231 and the fixing frame 220. Specifically, one end of the elastic element 240 is fixed to the linkage element 250, and the linkage element 250 passes through the fixing frame 220 and is fixed to the first sliding rail 2311. The other end of the elastic element 240 is fixed to the second fixing frame 2202, so that the elastic element 240 is in an initial stretching state. In the present embodiment, the elastic member 240 is a spring, but not limited thereto.
In the present embodiment, the sliding unit 230 further includes a switch 232, the switch 232 is connected to the slide rail set 231, and specifically, the switch 232 is fixed to the second slide rail 2312 for switching between an interference state and an unlocking state.
Specifically, when the switch 232 moves from the position shown in fig. 3B to the position shown in fig. 3C, the switch 232 interferes with the fixing frame 220 to be in an interference state, and the display unit 212 and the input unit 214 stay at a monitoring position shown in fig. 3F.
When the switch 232 reaches the position shown in fig. 3D from the position shown in fig. 3C, the interference between the switch 232 and the holder 220 is released to be in the unlocked state. At this time, the elastic element 240 is used to drive the sliding rail set 231 to move the display unit 212 and the input unit 214 to the operation positions shown in fig. 3G.
In this way, in the switch system 1 of the present embodiment, the slide rail set 231 can be driven by the elastic element 240 to achieve the effects of automatically flipping the display unit 212 and adjusting the tilt angle of the display unit 212, thereby improving the convenience of the user in operating the switch system 1.
In more detail, as shown in fig. 3A and 3B, in the present embodiment, the first slide rail 2311 has a first opening C1 and a second opening C2. The fixing frame 220 has a protrusion 221, an elastic member 222, a positioning rod 223 and a receiving member 224. In the present embodiment, the positioning rod 223 is engaged with the slot of the protrusion 221, and the elastic element 222 is sleeved on the positioning rod 223. In the present embodiment, the protrusion 221, the elastic member 222, and the positioning rod 223 are disposed on the accommodating member 224. The accommodating element 224 has an abutting surface 224A, the abutting surface 224A is perpendicular to the extending direction of the positioning rod 223, and two ends of the elastic element 222 abut against the abutting surface 224A and the protrusion 221 respectively.
In the embodiment, the elastic member 222 is a spring, and when the elastic member 222 is compressed or stretched, the positioning rod 223 can generate a guiding effect to enable the elastic member 222 to move more stably because the elastic member 222 is sleeved on the positioning rod 223. In other embodiments, the elastic member 222 may be made of foam, rubber or other compressible materials, or the fixing frame 220 may not include the positioning rod 223, which is not limited to the above.
Referring to fig. 1 and 3B, when the user does not use the switch system 1, the display unit 212 and the sliding unit 230 are located at the storage positions shown in fig. 1 and 3B, respectively. At this time, the protrusion 221 is driven by the elastic force of the elastic member 222 to extend into the first opening C1. In the embodiment, the protrusion 221 extends into the first opening C1 to limit the movement of the first slide track 2311.
Referring to fig. 3C and fig. 3F, when the user wants to use the switch system 1, the user can move the display unit 212 along with the second slide rail 2312 from the storage position shown in fig. 1 to the monitoring position shown in fig. 3F, and make the sliding unit 230 located at the monitoring position shown in fig. 3C. At this time, the bump 221 is still located in the first opening C1, and the bump 221 interferes with the switch 232 to make the display unit 212 stay at the monitoring position shown in fig. 3F.
Referring to fig. 3D, fig. 3E and fig. 3G, when the user wants to obtain a better operation angle, the user can move the display unit 212 along with the second slide rail 2312 from the monitoring position shown in fig. 3F to the operation position shown in fig. 3G. In the process of moving the display unit 212, the switch 232 moves together with the display unit 212, and the switch 232 applies a force greater than a predetermined value to the protrusion 221, so that the protrusion 221 is pushed by the switch 232 to remove the interference with the first opening C1. That is, the protrusion 221 exits the first opening C1, and the switch 232 of the sliding unit 230 is located at the unlocking position shown in fig. 3D.
When the interference between the switch 232 and the protrusion 221 is released, the elastic member 240 generates a pulling force to drive the sliding rail set 231 to move the display unit 212 to the operating position shown in fig. 3G in order to return to the original length from the original stretching state. When the display unit 212 and the sliding unit 230 are located at the operation positions shown in fig. 3G and fig. 3E, the protrusion 221 is driven by the elastic force of the elastic member 222 to extend into the second opening C2 to limit the first slide rail 2311 to move continuously.
In the present embodiment, when the display unit 212 is located at the monitoring position shown in fig. 3F, as shown in fig. 3C, the bump 221 interferes with the switch 232 through an inclined plane F. In the embodiment, the inclined plane F is inclined to the moving direction of the second slide track 2312, such a design way can make the bump 221 less prone to wear due to long-term use, but is not limited thereto.
In this embodiment, when the display unit 212 is located at the monitoring position shown in fig. 3F, the included angle between the display unit 212 and the moving direction of the slide rail set 231 is 90 degrees to 95 degrees, but when the display unit 212 is located at the operating position shown in fig. 3G, the included angle between the display unit 212 and the moving direction of the slide rail set 231 is greater than or equal to 115 degrees. In other words, the switch system 1 of the present embodiment can effectively increase the flip angle of the display unit 212.
Fig. 3H is a schematic view of the sliding unit and the fixing frame of fig. 2. Referring to fig. 3H, in the present embodiment, the switch system 1 further includes at least one fixing element 40, and the fixing element 40 is used to fix the switch 10 of fig. 2 to the fixing frame 220, so as to prevent the connection between the host computer and the display unit 212 or the input unit 214 from being disconnected due to being pulled. Note that, in order to clearly show the fixing member 40, the first fixing frame 2201 in fig. 3H is shown by a dotted line.
Fig. 3I is a partially enlarged sectional view of the sliding unit and the fixing frame of fig. 2. Referring to fig. 3I, in the present embodiment, the human-machine interface device 20 of fig. 2 further includes at least one gasket 260 disposed between the sliding rail set 231 and the fixing frame 220, so that the sliding rail set 231 and the fixing frame 220 can slide more smoothly and avoid abrasion. The spacer 260 may be a plastic material, such as PET.
Referring to fig. 3A and 3I, specifically, the upper side of the pad 260 abuts against the lower surface of the first slide rail 2311, and the lower side of the pad 260 abuts against the second holder 2202. In the present embodiment, the number of the spacers 260 is two. In another embodiment, the number of spacers 260 may also be one or more than one. In other embodiments, the hmi device 20 may also use a plurality of balls disposed between the sliding rail set 231 and the fixing frame 220, so as to enable the sliding rail set 231 and the fixing frame 220 to slide relatively smoothly, which is not limited herein.

The first slide rail 2311A includes a first slide rail 2311A1, a second slide rail 2311A2, a third slide rail 2311A3 and a fourth slide rail 2311A4, the first slide rail 2311A1 is slidably connected to the fixing frame 220A, the second slide rail 2311A2 is fixed to the first slide rail 2311A1, and the third slide rail 2311A3 and the fourth slide rail 2311A4 are respectively fixed to the second slide rail 2311A 2. The second slide rail 2312A and the third slide rail 2313A are slidably connected to the third sub-slide rail 2311A3 and the fourth sub-slide rail 2311A4, respectively. The second slide rail 2312A and the third slide rail 2313A are respectively fixedly connected with the display unit 212 and the input unit 214 of fig. 5. The first sub-slide track 2311A1 is slidably coupled in the first through hole H1 and the second through hole H2 by two guides G.
In this embodiment, the hmi device 20A further comprises at least one pad 260A, so as to enable the sliding rail set 231A and the fixing frame 220A to slide smoothly and avoid abrasion.
Referring to fig. 4 and 6B, when the user does not use the switch system 1A, the display unit 212 and the sliding unit 230A are located at the storage positions shown in fig. 4 and 6B, and at this time, the protrusion 221A interferes with the engaging portion D of the switch 232A.
When the user wants to use the switch system 1, the user can move the display unit 212 along with the second slide track 2312A from the storage position shown in fig. 4 to the monitoring position shown in fig. 6D. At this time, the first sliding rail 2311A1 does not slide relative to the fixing frame 220A yet, and the protrusion 221A further interferes with the engaging portion D of the switching piece 232A, so that the display unit 212 stays at the monitoring position shown in fig. 6D.
Referring to fig. 6C and 6E, when the user wants to obtain a better operation angle, the user can press a pressing side L of the switch 232A exposed outside with respect to the first slide rail 2311A, so that the switch 232A rotates with respect to the first slide rail 2311A around the pivot T, and the display unit 212 moves with the second slide rail 2312A from the monitoring position shown in fig. 6D to the operation position shown in fig. 6E. Specifically, when the user releases the interference between the engaging portion D and the switch 232A, the switch 232A is in the unlocked state. Moreover, since the elastic element 240A is in the stretched state initially, a pulling force is generated by the elastic element 240A to restore the original length so as to drive the sliding rail set 231A, so that the display unit 212 is pulled to move to the operating position shown in fig. 6E automatically.
In addition, in the embodiment, the hmi device 20A further includes a spring S, one end of the spring S is fixed to a first fixing portion P1 of the first slide rail 2311A, and the other end of the spring S is fixed to a second fixing portion P2 of the pressing side L of the switch 232A for maintaining the posture of the switch 232A relative to the first slide rail 2311A. That is, when the switching member 232A is pushed to rotate, the switching member 232A may return to the initial position by the spring S.
In summary, in the human-machine interface device and the switch system of the invention, two ends of the elastic element are respectively fixed to the slide rail set and the fixing frame. When the switching piece is in an interference state, the switching piece interferes with the fixing frame to enable the display unit to stay at a monitoring position. When the switching piece is in the unlocking state, the switching piece releases the interference with the fixed frame so that the display unit can leave the monitoring position. When the switching piece is in the unlocking state, the elastic piece drives the sliding rail set to enable the display unit to move to the operation position, and therefore the purpose of automatically turning over the display unit is achieved.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
