[0002] Currently, many components in automotive smart cockpits feature touch-sensitive controls, such as displays with touch and vibration feedback. Screen video signals are transmitted by the host computer via LVDS. Screen backlight signals, diagnostic signals, configuration parameters, and other functions also interact with the instrument cluster via LVDS communication.

It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0030] The terms "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side" used herein are merely references to the directions or positions in the accompanying drawings. These terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, an embodiment of the present invention is provided:

[0032] A shrapnel vibration sub-instrument display screen structure comprises a fixed bracket 1, a movable bracket 2 and a display screen assembly 3 mounted on the movable bracket 2, a vibration component 4 is provided in the middle between the fixed bracket 1 and the movable bracket 2, and shrapnel 5 is provided at the four corners of the vibration component 4. In this embodiment, four shrapnel 5 are symmetrically provided with the vibration component 4 as the center, and the shrapnel 5 is made of metal, and stainless steel can be optionally used; the shrapnel 5 comprises a U-shaped portion 51 and a first connecting portion 52 and a second connecting portion 53 provided on both sides of the U-shaped portion 51, wherein the R angle size of the U-shaped portion 51 determines the elastic performance of the shrapnel 5, and in this embodiment, the R angle is set to R1.6mm, which can reduce the pressure injury during bending, increase the strength at the R angle, and ensure that the shrapnel 5 does not break after a certain number of continuous vibrations; the first connecting portion 52 and the second connecting portion 53 are connected. 3 are both provided with first connecting holes 54 for bolting to the fixed bracket 1 and the movable bracket 2 respectively. The spring piece 5 can be bolted to the fixed bracket 1 and the movable bracket 2 respectively through the two first connecting holes 54 thereon, so that the movable bracket 2 is in a suspended state relative to the static bracket 1, and the assembly is convenient and quick; the first connecting part 52 and the second connecting part 53 are both provided with limiting ends 55 for limiting the fixed bracket 1 and the movable bracket 2 respectively, which can improve the stability of the connection between the movable bracket and the fixed bracket; the first connecting part 52 and the second connecting part 53 are both provided with anti-loosening spring pieces 56, and the anti-loosening spring pieces 56 are provided with second connecting holes 57 communicating with the first connecting holes 54. When the spring piece 5 and the movable bracket 2 are bolted to the fixed bracket 1, the probability of the bolt connection loosening due to vibration during long-term use can be reduced, thereby improving the stability of the vibration feedback of the display screen.

[0033] The anti-loosening spring piece 56 disposed on the first connecting portion 52 faces the U-shaped portion 51 and forms a certain angle with the first connecting portion 52. The anti-loosening spring piece 56 disposed on the second connecting portion 53 is away from the U-shaped portion 51 and forms a certain angle with the second connecting portion 53, wherein the angle is an acute angle, which is 30°-35° in this embodiment. One end of each anti-loosening spring piece 56 is connected to the first connecting portion 52 and the second connecting portion 53, and the connection is an S-shaped bend. With this opposing arrangement, when the spring piece 5 is connected to the fixed bracket 1 and the movable bracket 2, no other brackets are required, and the connection can be made directly through the spring piece 5 itself.

[0034] The four corners of the fixed bracket 1 are each provided with an installation cavity 101, and the spring piece 5 is installed in the installation cavity 101. The installation cavity 101 is provided with an opening on the side close to the electromagnet assembly 41. When assembling the second connecting part 53 and the movable bracket 2, a bolt can be installed from the opening. The limiting end 55 of the spring piece 5 includes a clamping groove 501 provided on the first connecting part 52 and the second connecting part 53. The installation cavity 101 is provided with a first clamping part 502 that cooperates with the clamping groove 501 at the first connecting part 52, and the lower end surface of the movable bracket 2 is provided with a second clamping part 503 that cooperates with the clamping groove 501 at the second connecting part 53. In this embodiment, the clamping grooves 501 are formed on both sides of the first connecting hole 54 of each connecting part by bending the metal sheet, and then connected with the bolt in the middle, which greatly improves the stability and firmness of the connection between the movable bracket and the fixed bracket.

[0035] Furthermore, the clamping slot 501 is provided with a guide portion 504 . The guide portion 504 is formed by the ends of both sides of the clamping slot 501 being opened outwards, so as to facilitate the installation of the spring piece 5 and improve the assembly efficiency.

[0036] The vibration component 4 includes an electromagnet component 41 and an armature 42. The lower end surface of the dynamic bracket 2 is provided with an armature fixing platform 19. The armature 42 is an L-shaped metal plate. The armature fixing platform 19 is provided with a limiting portion to prevent the armature 42 from moving in the Y-axis direction. The armature 42 is provided with two long waist holes along the X-axis direction and is connected to the armature fixing platform 19 by bolts. A fixed connecting hole is provided between the two long waist holes, and a fixing protrusion that cooperates with the fixed connecting hole is provided on the armature fixing platform 19. After connection, the armature 42 can move synchronously with the armature fixing platform 19. The fixed bracket 1 is provided with an electromagnet assembly mounting cavity 18. The electromagnet assembly mounting cavity 18 is provided with a limiting groove to fix the electromagnet assembly 41 therein, and the electromagnet assembly 41 is connected to the bottom of the limiting groove by bolts.

[0037] The electromagnet assembly 41 can attract the armature 42 along the X-axis direction, and the spring piece 5 will be deformed along the attraction direction, that is, the X-axis direction. After the attraction stops, under the action of elasticity, the spring piece 5 recovers the deformation and generates vibration along the X-axis direction. Several groups of Y-axis limit assemblies 6 and Z-axis limit assemblies 7 are arranged between the movable bracket 2 and the fixed bracket 1. In this embodiment, two groups of Y-axis limit assemblies 6 and four groups of Z-axis limit assemblies 7 are provided. The Y-axis limit assemblies 6 and the Z-axis limit assemblies 7 are mainly used for motion limiting under unconventional operations, and can also avoid hard contact of components during vibration, thereby improving the service life of the equipment.

[0038] Vibration realization path: Vibration instructions are input through touch, and then current is output to the electromagnet assembly 41. Then the electromagnet assembly 41 attracts the armature 42 and releases it. Finally, the U-shaped part 51 of the spring 5 drives the bracket 2 to rebound and generate vibration.

[0039] Specifically, the Y-axis direction limit assembly 6 includes a limit protrusion 61 provided on the lower end surface of the movable bracket 2, a limit groove 62 provided on the upper end surface of the fixed bracket 1, and a first limit rubber 63. The side wall of the limit groove 62 is provided with a clamping groove 64. The middle part of the first limit rubber 63 is provided with a through hole 65 for the limit protrusion 61 to be inserted. The outer wall of the limit rubber 63 is provided with a clamping block 66 that is engaged with the clamping groove 64. The inner wall of the through hole 65 is provided with a clamping ridge 67. The two side walls of the limit protrusion 61 in the X-axis direction are inclined toward the middle of the two, so that the limit protrusion 61 has movement space in the X-axis direction when located in the through hole 65, and the two side walls of the limit protrusion 61 in the Y-axis direction are abutted against the clamping ridge 67 on the inner wall of the through hole 65. During assembly, the first limit rubber 63 is inserted into the limit groove 62, and the clamping block 66 is clamped and limited with the clamping groove 64, and then the limit protrusion 61 is inserted into the through hole 65.

[0040] Specifically, the Z-axis direction limit assembly 7 includes a first limit boss 71 arranged on the lower end surface of the movable bracket 2, a second limit boss 72 and a second limit rubber 73 arranged on the upper end surface of the fixed bracket 1, and a socket 74 is provided in the middle of the second limit boss 72 to be plugged into the second limit rubber 73. The distance between the first limit boss 71 and the second limit rubber 73 is smaller than the distance between the lower end surface of the movable bracket 2 and the upper end surface bracket of the static bracket 1 to prevent overpressure in the Z-axis direction.

[0041] Specifically, the Z-axis direction limit assembly 7 also includes a fixed column 15 arranged on the lower end surface of the movable bracket 2, a fixed hole 17 and a pressure plate 16 arranged on the upper end surface of the fixed bracket 1. One end of the fixed column 15 passes through the fixed hole 17 and is connected to the pressure plate 16. A limiting end is provided on the fixed column 15 for the pressure plate 16 to be snapped into and fixed by bolts. The pressure plate 16 is abutted against the lower end surface of the fixed bracket 1 to prevent it from warping in the Z-axis direction. Furthermore, an elastic pad is provided at the position where the pressure plate 16 abuts against the lower end surface of the fixed bracket 1.

[0042] The display screen assembly 3 includes a display screen bracket 31, within which a sensing glass 32 and a glass cover 33 are disposed. The glass cover 33 is disposed on the upper end surface of the movable bracket 2 with a VHB tape 34 disposed therebetween. Optical adhesive layers 35 are disposed on both the upper and lower end surfaces of the sensing glass 32. The sensing glass 32 is located between the glass cover 33 and the display screen bracket 31, and foam 36 is disposed between the display screen bracket 31 and the movable bracket 2. When a finger touches the glass cover 33, the human body causes a change in the capacitance value on the sensing glass 32, thereby determining the coordinates of the finger's touch point and achieving the corresponding function.

[0043] A pressure sensing circuit board 8 and a main circuit board 9 are arranged in the fixed bracket 1 , and an electromagnet connector 10 , an LVDS connector 11 and a patch pin assembly 12 are connected to the lower end surface of the main circuit board 9 .

[0044] A base 13 is provided at the bottom of the fixed bracket 1 , and the patch pin assembly 12 extends out of the base 13 with a protective cover 14 provided therebetween.

[0045] The pressure sensing circuit board 8 is provided with a plurality of induction coils, and the lower end surface of the movable bracket 2 is provided with a corresponding metal conductor 81, preferably aluminum alloy, and a certain distance is set between the induction coil and the metal conductor 81. In this embodiment, the distance between the induction coil and the metal conductor 81 is 1 mm.

[0046] This structure uses displacement detection (inductive sensing) and eddy current detection principles: When the sensor system power is turned on, a high-frequency signal is generated in the preamplifier. This signal is sent to the probe head via a cable, generating an alternating magnetic field H1 around the head. If a metal conductor 81 approaches the probe head, the alternating magnetic field H1 will generate an eddy current field on the surface of the metal conductor 81. This eddy current field will also generate an alternating magnetic field H2 in the opposite direction to H1. Due to the reaction of H2, the amplitude and phase of the high-frequency current in the probe head coil will be changed, thereby changing the effective impedance of the coil. Through processing in the preamplifier's electronic circuitry, the change in coil impedance Z—that is, the change in the distance d between the head body coil and the metal conductor 81—is converted into a change in voltage or current. The magnitude of the output signal varies with the distance between the probe and the surface of the object being measured.

[0047] A dustproof component is provided between the fixed bracket 1 and the moving bracket 2, and the dustproof component includes a dust-isolating ring 20 which is sleeved between the fixed bracket 1 and the moving bracket 2. Both the fixed bracket 1 and the moving bracket 2 are provided with an annular groove 21 for inserting the dust-isolating ring 20. At least two sealing rings 22 are provided on the inner wall of the dust-isolating ring 20 and the annular groove 21. Several elastic members 23 are provided between the dust-isolating ring 20 and the bottom of the annular groove 21 on the fixed bracket 1 and the moving bracket 2. A limiting structure 24 is provided at the position where the dust-isolating ring 20 and the bottom of the annular groove 21 and the elastic member 23 abut against each other. The limiting structure 24 can be a protrusion or a groove. By providing the dustproof component, dust and impurities can be effectively prevented from entering the interior of the display screen through the vibration gap between the fixed bracket 1 and the moving bracket 2.

[0048] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
