Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application.
Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present application. However, those of ordinary skill in the art will appreciate that the embodiments of the invention that may be practiced are not limited to only one and that other methods, apparatus, steps, etc. may be used. In other instances, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
First embodiment
Referring to fig. 1, 2 and 3, fig. 1 is a schematic diagram of a vehicle display 100 according to an embodiment of the invention, fig. 2 is an exploded schematic diagram of the vehicle display 100 according to an embodiment of the invention, and fig. 3 is a schematic cross-sectional diagram of the vehicle display 100 according to an embodiment of the invention. The vehicle display 100 includes a display module 110, a base 120, a spindle portion 130, a variable damping fluid 140, and a crush can 150.
The display module 110 and the base 120 are disposed on a dashboard or a center console of a vehicle, for example, and can be configured in a floating manner, so that the limitation of the conventional embedded mechanism can be overcome, and the display area of the screen can be enlarged, for example, 9 to 12 inches or more, and a large amount of video information, maps, driving information and the like can be displayed. The display module 110 is, for example, a liquid crystal display, an organic light emitting diode display, or other suitable vehicle mounted anti-glare display.
The rotation shaft 130 is pivotally connected between the display module 110 and the base 120, so that the display module 110 can rotate relative to the base 120. As shown in fig. 2, the shaft portion 130 is located in the rear sleeve 112 of the display module 110, and two ends of the shaft portion 130 may be fixed on the bracket 122 of the base 120 by two pins 136, so that the shaft portion 130 may rotate. In addition, the shaft 130 may further include a positive electrode plate 132 and a negative electrode plate 134, where the positive electrode plate 132 and the negative electrode plate 134 are formed by two concentric cylinders, and the positive electrode plate 132 and the negative electrode plate 134 are separated by a gap, such as 1mm or other values, for filling the variable damping fluid 140. In the present embodiment, the negative electrode plate 134 is positioned in the positive electrode plate 132, and both ends of the positive electrode plate 132 and the negative electrode plate 134 are sealed with oil seals 142 to prevent the variable damping fluid 140 from leaking out. In another embodiment, the positive electrode plate 132 is, for example, located in the negative electrode plate 134, which is not limited to the present invention.
Referring to fig. 3, a variable damping fluid 140 is electrically controllable received between the positive electrode plate 132 and the negative electrode plate 134. In this embodiment, the variable damping fluid 140 is, for example, electrorheological fluid (electro-rheological fluid) or magnetorheological fluid (magnetorheological fluid), which is a fluid that can change its flow properties (mainly viscosity coefficient or damping force) with an electric field or a magnetic field. Electrorheological fluids are generally suspensions of semiconductor particles in a dielectric oil; magnetorheological fluids are suspensions of magnetic particles in a non-magnetic oil. The flow principle of the two fluids is the same, wherein the electric field polarizes the semiconductor particles of the electrorheological fluid; the magnetic field magnetizes the magnetic particles of the magnetorheological fluid and the magnetic particles are distributed linearly, so that the flow property of the magnetorheological fluid or the magnetorheological fluid is changed. When the electric field or the magnetic field is removed, the flow performance of the electrorheological fluid or the magnetorheological fluid can be restored.
That is, the variable damping fluid 140 has a first damping force when being applied by an applied electric field or magnetic field, and the variable damping fluid 140 has a second damping force when not being applied by the applied electric field or magnetic field, wherein the first damping force is greater than the second damping force. The first damping force is formed by solidification of polarized electrorheological fluid and can be used as vibration damping force for blocking external vibration, and the second damping force is formed by unpolarized electrorheological fluid and can be used for absorbing head impact force by utilizing a crumple mechanism when a subsequent vehicle is impacted.
Therefore, the vehicle display 100 of the present embodiment can utilize the polarized flow property (viscosity coefficient or damping force increase) of the variable damping fluid 140 to perform vibration isolation so as to absorb the vibration transmitted from the power system or chassis of the vehicle via the road surface, and utilize the unpolarized flow property (viscosity coefficient or damping force decrease) of the variable damping fluid 140 to enable the vehicle display 100 to start the collapse mechanism at the moment of the collision of the vehicle so as to absorb the head impact force, thereby avoiding the excessive acceleration when the head impacts the vehicle display 100 and meeting the legal requirements of the vehicle display 100.
In one embodiment, the crush-supporting frame 150 is made of metal, plastic or other equivalent material, and is connected between the display module 110 and the base 120 by two locking members 152. The collapsing support 150 has a collapsing area 154, which is collapsed by being impacted at the moment of a collision of the vehicle or when the control system fails and is not powered, so that the display module 110 rotates relative to the rotating shaft 130 to absorb the impact force of the head. That is, when the damping force of the variable damping fluid 140 is reduced and proper support is not provided at the moment of the collision of the vehicle or when the control system fails, the collapsing support frame 150 can be used as an auxiliary fixing device, and unnecessary rotation of the display module 110 relative to the base 120 can be avoided.
Second embodiment
Fig. 4 and 5 are an exploded view and a cross-sectional view, respectively, of a spindle 130' according to another embodiment of the invention. The rotation shaft 130' of the present embodiment is substantially the same as the rotation shaft 130 of the first embodiment described above in function, except that: the positive electrode plate 132 and the negative electrode plate 134 of the first embodiment are composed of two concentric cylinders with smooth surfaces, and the positive electrode plate 132 'and the negative electrode plate 134' of the present embodiment are composed of two concentric cylinders with relatively concave-convex structures on the surfaces, so as to increase the channel length and the channel area between the electrode plates. Thus, more of the variable damping fluid 140 may fill the wavy or concave-convex gaps and increase the polarization of the variable damping fluid 140.
In the present embodiment, the negative electrode plate 134' is composed of, for example, two convex columns 133,135 having a stepped surface and being inserted as one body, so as to form a cylinder with a concave middle and convex sides. The two protrusions 133,135 of the negative electrode plate 134' can be respectively inserted from both ends of the positive electrode plate 132' to be received in the positive electrode plate 132', and then both ends of the positive electrode plate 132' and the negative electrode plate 134' are sealed with oil seals 142 to prevent the variable damping fluid 140 from leaking out, as shown in fig. 5.
Referring to fig. 6 and 7, fig. 6 is a schematic diagram of a control system 10 of a vehicle display 100 according to an embodiment of the invention, and fig. 7 is a schematic diagram of a control flow of the vehicle display 100 according to an embodiment of the invention, wherein the control flow includes the following steps S10 to S60.
The control system 10 may include a controller 20, an ignition signal source 30, a crash acceleration sensor 40, a Pre-Driver 50, a drive switch 52, a burst Driver 54, a power source 60, and a high voltage power converter 70, wherein the ignition signal source 30 is configured to detect a vehicle power-on signal, and the crash acceleration sensor 40 is configured to detect a vehicle post-crash acceleration signal. The pre-driver 50 can turn on the driving switch 52 to supply the power 60 to the blasting driver 54 when the vehicle is crashed, and activate the airbag 80 and the belt pretensioner 90 by the blasting driver 54 to protect the safety of the passengers. The controller 20 is, for example, a driving computer, and detects whether the vehicle power is turned on or whether the vehicle engine is started (refer to step S10), and if it is determined that the vehicle power/engine is turned on, it is further determined whether the vehicle is crashed (refer to step S20).
In addition, the high voltage power converter 70 is configured to provide an external electric field to the variable damping fluid 140 of the vehicle display 100, and when the controller 20 detects an external impact, it can provide a power-off signal to the high voltage power converter 70 to cut off the external electric field or magnetic field (refer to step S30), so that the damping force of the variable damping fluid 140 is reduced (refer to step S40), and the vehicle display 100 can start the collapsing mechanism at the moment of the vehicle collision to reduce the head impact force. In addition, when the controller 20 does not detect the external impact, the controller 20 may provide a power-on signal to the high-voltage power converter 70 to provide an external electric field or a magnetic field (see step S50), so as to increase the damping force of the variable damping fluid 140 (see step S60) as a damping force for blocking the external vibration.
In summary, although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Those skilled in the art to which the present invention pertains will appreciate that numerous modifications and variations can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be determined from the following claims.
