Description

[0001] This application is a divisional application of the invention application for a novel snap-fit ​​display, with the original application number being 202111162364.6 and the application date being 2021.09.30. Technical Field

[0002] This application relates to the field of display technology, and in particular to an active vibration damping display. Background Technology

[0003] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0004] A liquid crystal display (LCD) is an active-matrix liquid crystal display driven by thin-film transistors (TFTs). It primarily uses electric current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, in conjunction with a backlight, form the image. IPS, TFT, and SLCD are all subcategories of LCDs. Its working principle is that under the influence of an electric field, the alignment of liquid crystal molecules changes, modulating the transmittance of an external light source to complete an electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals, and passing through red, green, and blue primary color filters, color reproduction in the temporal and spatial domains is achieved. Generally, the video and power cables of a monitor are connected separately to the back of the monitor. Rotating the monitor can easily pull on these cables. Furthermore, in non-stationary installation locations, such as on moving vehicles in rough road conditions, the monitor lacks necessary shock absorption. These problems are particularly pronounced as LCDs become larger and thinner. Summary of the Invention

[0031] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 9 As shown, this application provides an active vibration damping display, including a display body 1 and a bracket. The bracket includes a fixed base 2 and a connecting shaft 3 disposed on the fixed base 2. A rotating seat 4 is rotatably sleeved on the top end of the connecting shaft 3. A snap-fit ​​box 5 is fixedly connected to one side of the rotating seat 4. The side of the snap-fit ​​box 5 away from the rotating seat 4 is open to the outside, and a vibration damping mechanism and an escapement mechanism are disposed inside the snap-fit ​​box 5. A snap-fit ​​plate 6 is connected to the snap-fit ​​box 5 through the vibration damping mechanism. The escapement mechanism is movably connected to the vibration damping mechanism for turning the vibration damping function on and off.

[0035] The connecting shaft 3, rotating seat 4, snap-fit ​​box 5, shock-absorbing mechanism, and snap-fit ​​plate 6 are all equipped with wire channels for threading wires. A wire interface 301 is located on one side of the connecting shaft 3. The snap-fit ​​plate 6 and the display body 1 are mechanically and electrically connected via mutually compatible snaps. External video and power signals are connected to internal wires via the wire interface 301. Internal wires are connected to the shock-absorbing mechanism and escapement mechanism via the wire channels inside the connecting shaft 3, rotating seat 4, and snap-fit ​​box 5. They are then connected to the display body 1 via the wire channels inside the shock-absorbing mechanism and snap-fit ​​plate 6, allowing for on / off connection via snaps. This wire channel within the bracket enables power supply and control of the shock-absorbing mechanism and escapement mechanism, as well as power supply and video signal transmission to the display body 1. This prevents the relative movement of components caused by the rotation and shock absorption of the display body 1 from pulling on the wires and causing malfunctions in the display body 1.

[0036] Specifically, the shock absorption mechanism includes a support plate 7 disposed within the snap-fit ​​box 5 and a main shock absorption mechanism 8 and a secondary shock absorption mechanism 9 disposed between the support plate 7 and the snap-fit ​​plate 6.

[0037] Furthermore, the main damping mechanism 8 includes a main sleeve 803, which is laterally arranged in the middle of the support plate 7. A main sliding shaft 801 is slidably and rotatably inserted inside the main sleeve 803. A middle fixing block 606 is provided at both ends of the main sliding shaft 801. The middle fixing block 606 is connected to the snap-fit ​​plate 6. A main spring 802 is connected between the main sleeve 803 and the two middle fixing blocks 606 respectively. The main spring 802 is sleeved on the main sliding shaft 801.

[0038] The main shock absorption mechanism 8 converts the lateral vibration of the display body 1 into relative motion between the main sleeve 803 and the main sliding shaft 801, and then buffers and absorbs the vibration through the main spring 802. At the same time, it converts the vertical and front-back vibration of the display body 1 into relative oscillation between the snap plate 6 and the support plate 7, and then buffers and absorbs the vibration through the secondary shock absorption mechanism 9.

[0039] The secondary damping mechanism 9 includes a secondary sliding shaft 902. Two side fixing blocks 901 are respectively vertically mounted on the top and bottom side walls of the support plate 7. The secondary sliding shaft 902 is located between the two side fixing blocks 901. Two secondary sleeves 903 are slidably and rotatably mounted on the secondary sliding shaft 902. A secondary spring 904 is connected between the two secondary sleeves 903. The secondary spring 904 is mounted on the secondary sliding shaft 902. A telescopic adjusting rod 905 is rotatably connected to the side wall of the secondary sleeve 903. The end of the adjusting rod 905 is movably connected to the snap-fit ​​plate 6.

[0040] The secondary damping mechanism 9 transmits the swing between the snap plate 6 and the support plate 7 to the secondary sleeve 903 via the adjusting rod 905, thereby converting the swing into the sliding of the two secondary sleeves 903 on the secondary sliding shaft 902, and then buffering and damping through the secondary spring 904.

[0041] The escapement mechanism includes a push-pull mechanism 501 and a holding mechanism 502. The push-pull mechanism 501 is located on the end side wall of the snap-fit ​​box 5 and its output shaft is connected to the support plate 7. The holding mechanism 502 is embedded in the inner walls of the snap-fit ​​box 5. The output shaft of the holding mechanism 502 simultaneously abuts against the side walls of the support plate 7 and the snap-fit ​​plate 6.

[0042] When vibration damping is activated, the output of the pressing mechanism 502 moves away from the central axis of the snap-fit ​​box 5, releasing the pressure on the support plate 7 and the snap-fit ​​plate 6. The push-pull mechanism 501 pushes the support plate away from the rotating seat 4 until the support plate 7 is pushed out of the snap-fit ​​box 5, thus initiating vibration damping. When vibration damping is deactivated, the push-pull mechanism 501 pulls the support plate 7 into the snap-fit ​​box 5, and the output of the pressing mechanism 502 moves towards the central axis of the snap-fit ​​box 5 until the support plate 7 and the snap-fit ​​plate 6 are pressed together, thus deactivating the vibration damping capability of the vibration damping mechanism. When the push-pull mechanism 501 pulls the support plate 7 into the snap-fit ​​box 5, the snap-fit ​​plate 6 abuts against the snap-fit ​​box 5, with a portion of the snap-fit ​​plate 6 entering the snap-fit ​​box 5 and the other portion remaining outside.

[0043] Specifically, the push-pull mechanism 501 is an electric cylinder, and the pressing mechanism 502 includes a pressing electric cylinder and a pressing bar connected to the output shaft of the pressing electric cylinder.

[0044] The adjusting rod 905 includes a hinge frame 951 connected to the secondary sleeve 903. The top of the hinge frame 951 is connected to a first telescopic mechanism 952. The output shaft of the first telescopic mechanism 952 is connected to a connecting rod 953. The end of the connecting rod 953 is provided with a universal ball joint 954. The snap-fit ​​plate 6 is provided with a connecting seat 605 adapted to the universal ball joint 954. The universal ball joint 954 and the connecting seat 605 are movably connected.

[0045] Specifically, the first telescopic mechanism 952 is an electric cylinder or an electric push rod.

[0046] The first telescopic mechanism 952 extends and retracts, causing the secondary sleeve 903 to slide on the secondary slide shaft 902. The extension and retraction of the two first telescopic mechanisms 952 on the same adjusting rod 905 can adjust the distance between the two corresponding secondary sleeves 903, that is, adjust the compression length of the secondary spring 904, thereby adjusting the elastic force of the secondary spring 904, and thus adjusting the damping capacity of the secondary damping mechanism 9.

[0047] The main sleeve 803 has adjusting baffles 805 at both ends, which are slidably mounted on the main slide shaft 801. A second telescopic mechanism is embedded within the main sleeve 803, and the two output shafts of the second telescopic mechanism are respectively connected to the two adjusting baffles 805. One end of the main spring 802 is connected to the adjusting baffle 805, and the other end is connected to the central fixing block 606. Preferably, an adjusting slide rail 806 is provided on the support plate, and the bottom of the adjusting baffle 805 slides on the adjusting slide rail 806.

[0048] The output shaft of the second telescopic mechanism drives the adjusting baffle 805 to move along the main sliding shaft 801, thereby adjusting the distance between the adjusting baffle 805 and the middle fixed block 606, thereby adjusting the telescopic length of the main spring 802, thereby adjusting the damping force of the main spring 802, and thereby adjusting the damping capacity of the main damping mechanism 8.

[0049] The second telescopic mechanism includes a drive screw 807 disposed within the main sleeve 803. Two push-pull sliders 808 with opposite threads are slidably mounted on the drive screw 807. Push-pull shafts 804 are connected to the push-pull sliders 808. The two push-pull shafts 804 respectively penetrate the main sleeve 803 and are connected to two adjusting baffles 805. Preferably, guide protrusions 809 are provided at both ends of the inner cavity of the main sleeve 803. The push-pull shafts 804 extend through the guide protrusions 809 and the sidewall of the main sleeve 803 to the outside of the main sleeve 803. The guide protrusions 809 make the sliding of the push-pull shafts 804 more stable.

[0050] The drive screw 807 includes a drive motor and a screw. The rotation of the motor drives the screw to rotate, which in turn drives the two push-pull sliders 808 to move in opposite directions, thereby adjusting the length of the push-pull shaft 804 extending out of the main sleeve 803.

[0051] The main sleeve 803 is also provided with a main electric slip ring 10 and a power transmission ring 11. The power transmission ring 11 is fixedly sleeved on the main sliding shaft 801. The main electric slip ring 10 is arranged around the outer periphery of the main sliding shaft 801 and its stator part is fixed to the inner wall of the main sleeve 803. The power transmission ring 11 is connected to the rotor part of the main electric slip ring 10 through the main telescopic tube 12. The main sliding shaft 801, the power transmission ring 11, and the main telescopic tube 12 are provided with interconnected wire channels. The wires are connected to the stator part of the main electric slip ring 10 through the wire channels inside the support plate 7, and then connected to the wire channels inside the snap-fit ​​plate 6 through the rotor part of the main electric slip ring 10 via the main telescopic tube 12, the power transmission ring 11, and the main sliding shaft 801.

[0052] A secondary slip ring 906 is provided on the side of the secondary sleeve 903 away from the secondary spring 904. The secondary slip ring 906 is arranged around the outer periphery of the secondary sliding shaft 902 and its stator part is fixed to the secondary sliding shaft 902. The secondary sleeve 903 is connected to the rotor part of the secondary slip ring 906 through the secondary telescopic tube 907. The secondary telescopic tube 907, the side wall of the secondary sleeve 903, and the hinge frame 951 are provided with interconnected wire channels. The wires are connected from the support plate 7 and the wire channels in the secondary sliding shaft 902 to the stator part of the secondary sliding shaft 902, and then connected to the first telescopic mechanism 952 through the rotor part of the secondary slip ring 906, the secondary telescopic tube 907, the side wall of the secondary sleeve 903, and the wire channels in the hinge frame 951.

[0053] The main telescopic tube 12 and the secondary telescopic tube 907 are structured with large and small sleeves interlocking. The main electric slip ring 10, in conjunction with the internal wire channels of each component, is used for power and communication connections to the display body 1. The secondary electric slip ring 906 is used for power and communication connections to the first telescopic mechanism 952, thus preventing the relative movement of each component when the shock absorber is activated from pulling on the wires and causing display malfunction.

[0054] The snap-fit ​​plate 6 is provided with two longitudinal protrusions 602, two transverse protrusions 601, and snap-fit ​​holes 603. The display body 1 is provided with snap-fit ​​springs 101, two guide grooves 103, and two guide insertion holes 102. The transverse protrusions 601 are adapted to the guide grooves 103, the snap-fit ​​holes 603 are adapted to the snap-fit ​​springs 101, and the longitudinal protrusions 602 are adapted to the guide insertion holes 102. A retractable plug 607 is embedded at the end of the longitudinal protrusion 602, and a socket is provided on the inner wall of the guide insertion hole 102. The display body 1 has an internal mounting cavity, and two pressing through holes are opened on the top wall of the mounting cavity. The snap-fit ​​springs 101 are connected to the side wall of the mounting cavity and are provided with pressing protrusions and snap-fit ​​protrusions. The pressing protrusions and snap-fit ​​protrusions extend to the outside of the display body 1 through the pressing through holes.

[0055] The top end face of the longitudinal protrusion 602 is provided with a telescopic groove 604 that communicates with the end. The telescopic plug 607 includes a plug slider that slides in the telescopic groove 604 and a push rod provided on the plug slider.

[0056] When connecting the snap-fit ​​plate 6 and the display body 1, the longitudinal protrusion 602 is inserted into the guide socket 102, and the transverse protrusion 601 is inserted into the limiting groove opened on the front end face of the guide slot plate 103. The two guide slot plates 103 abut against the side wall of the snap-fit ​​box 5. The snap-fit ​​protrusion on the front side of the snap-fit ​​spring 101 is inserted into the snap-fit ​​hole 603. The snap-fit ​​plate 6 and the display body 1 are fixed. Then, push the push rod to move the plug slider until the plug on the plug slider and the socket in the guide socket 102 are connected, thereby realizing the mechanical and electrical connection between the display body 1 and the snap-fit ​​plate 6. When it is necessary to separate the snap-fit ​​plate 6 and the display body 1, push the push rod to move the plug slider so that the plug on the plug slider and the socket in the guide socket 102 are disengaged. Then, press the pressing protrusion at the rear of the snap-fit ​​spring 101 to move the snap-fit ​​protrusion away from the snap-fit ​​hole 603, thereby realizing the separation of the display body 1 and the snap-fit ​​plate 6.

[0057] The fixed base 2 is provided with a control button 201 electrically connected to the escapement mechanism and the shock absorption mechanism. This application also includes a controller embedded in the fixed base 2. The mechanical button 201 is electrically connected to the controller. The first telescopic mechanism 952, the second telescopic mechanism, the push-pull mechanism 501, and the pressing mechanism 502 are also electrically connected to the controller. The mechanical button 201 transmits control signals to the controller, which then controls the first telescopic mechanism 952, the second telescopic mechanism, the push-pull mechanism 501, and the pressing mechanism 502 to activate and deactivate the shock absorption function and adjust the shock absorption capacity.

[0058] The controller is a single-chip microcomputer device.

[0059] This application also provides a method of using a novel snap-fit ​​structure display, including:

[0060] How to connect the stand and the monitor:

[0061] S100: The longitudinal protrusion 602 of the snap-fit ​​plate is inserted into the guide socket 102, and the transverse protrusion 601 is inserted into the limiting groove opened on the front end face of the guide slot plate 103. The front protrusion of the snap-fit ​​spring 101 is inserted into the snap-fit ​​hole 603. The snap-fit ​​plate 6 and the display body 1 are fixed. Then, the push rod of the retractable plug 607 is pushed to drive the plug slider to move until the plug on the plug slider and the socket in the guide socket 102 are connected.

[0062] How to turn the shock absorbers on and off:

[0063] S201: The output part of the holding mechanism 502 of the escapement mechanism moves away from the central axis of the snap-fit ​​box 5, releasing the holding on the support plate 7 and the snap-fit ​​plate 6. The push-pull mechanism 501 pushes the support plate away from the rotating seat 4 until the support plate 7 is pushed out of the snap-fit ​​box 5, thereby causing the vibration damping mechanism to start damping.

[0064] S202: The push-pull mechanism 501 pulls the support plate 7 into the snap-fit ​​box 5. The output part of the pressing mechanism 502 moves toward the direction close to the central axis of the snap-fit ​​box 5 until the support plate 7 and the snap-fit ​​plate 6 are pressed together, thereby turning off the vibration damping capability of the vibration damping mechanism.

[0065] Shock absorption capacity adjustment methods:

[0066] S301: The output shaft of the second telescopic mechanism drives the adjusting baffle 805 to move along the main sliding shaft 801, thereby adjusting the distance between the adjusting baffle 805 and the middle fixed block 606, thereby adjusting the telescopic length of the main spring 802, thereby adjusting the damping force of the main spring 802, and thereby adjusting the damping capacity of the main damping mechanism 8.

[0067] S302: The first telescopic mechanism 952 extends and retracts, causing the secondary sleeve 903 to slide on the secondary sliding shaft 902. The extension and retraction of the two first telescopic mechanisms 952 on the same adjusting rod 905 can adjust the distance between the two corresponding secondary sleeves 903, that is, adjust the compression length of the secondary spring 904, thereby adjusting the elastic force of the secondary spring 904, and thus adjusting the damping capacity of the secondary damping mechanism 9.
