Description

Technical Field

[0001] The present invention relates to the technical field of display device protection, and in particular to a protection device for a digital media display device. Background Art

[0002] Display device protection mainly refers to a series of measures taken to protect the screen, internal electronic components and overall structure of digital media display devices (such as LCD monitors, LED displays, OLED displays or projectors, etc.) from damage by external physical, chemical or environmental factors. These measures include the use of various protective devices, materials and technologies to ensure that the display equipment can operate normally, stably and safely, and extend its service life.

[0003] When using existing digital media display devices, it is usually necessary to set up the display devices upright, and most of the existing corresponding protective devices only play an anti-collision role and cannot effectively prevent tipping over. When the display device itself is hit by external force, it is easy to tip over. At this time, even if the protective device plays a certain collision isolation role, the display device itself will be damaged by the internal components after tipping over, thereby affecting the normal use and service life of the display device itself.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the protective devices of digital media display devices currently on the market, and even if they can be solved, they need to be solved through external tools, which cannot achieve the desired effect.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The present invention provides a technical solution: a protective device for a digital media display device, comprising a main body mechanism 1, the main body mechanism 1 comprising a display body 11, the outer surface of the display body 11 is fixedly connected to a shell 12, both sides of the shell 12 are provided with a frame 13, the inner wall of each frame 13 is fixedly connected to a support bearing 14, the inner ring of each support bearing 14 is fixedly connected to a pillar 15, the ends of the two pillars 15 close to each other are fixedly connected to the two side surfaces of the shell 12, and the outer side of the shell 12 is provided with an anti-tilting stabilizing base mechanism 2;

[0040] The anti-tilt stabilizing mechanism 2 includes a buffer unit 21, which is arranged outside the housing 12 and is used to buffer the external force on the upper, lower, left, and right parts of the display body 11 and reduce the inertial relative shaking of the upper, lower, left, and right parts of the display body 11 caused by the external force.

[0041] As a further limitation of the anti-tilt stabilizing base mechanism 2 of the present invention, the buffer unit 21 includes four vertical shells 2101, wherein the left sides of two vertical shells 2101 are fixedly connected to the right side side of one of the frame frames 13, and the right sides of the other two vertical shells 2101 are fixedly connected to the left side of another frame frame 13, wherein the inner bottom walls of the two vertical shells 2101 and the inner top walls of the other two vertical shells 2101 are fixedly connected with the first damper 2102, the telescopic end of each first damper 2102 is fixedly connected with the first moving block 2103, the outer surface of each first moving block 2103 is slidably connected to the inside of the vertical shell 2101, the outer surface of each first damper 2102 is sleeved with a first buffer spring 2104, and each first The two ends of the buffer spring 2104 are in contact with the inner wall of the vertical shell 2101 and the outer surface of the first moving block 2103 respectively. A first buffer frame 2105 is provided on the side of each vertical shell 2101 close to the display body 11. The side of each first buffer frame 2105 away from the display body 11 is fixedly connected to the outer surface of the first moving block 2103. The inner wall of each first buffer frame 2105 is fixedly connected to a first guide rod 2106. The outer surface of each first guide rod 2106 is slidably connected to a first connecting block 2107. The side of each first connecting block 2107 close to the outer surface of the outer shell 12 is fixedly connected to the outer surface of the outer shell 12. The outer surface of each first guide rod 2106 is sleeved with two first return springs 2109. The two ends of the force spring 2109 are in contact with the inner wall of the first buffer frame 2105 and the outer surface of the first connecting block 2107 respectively, the inner wall of each first connecting block 2107 is fixedly connected with a first wear-resistant damping ring 2108, the inner wall of each first wear-resistant damping ring 2108 is in contact with the outer surface of the first guide rod 2106, a bottom plate 2112 is arranged below the outer shell 12, the upper surface of the bottom plate 2112 is fixedly connected with two transverse shells 2113, the inner side wall of each transverse shell 2113 is fixedly connected with a second damper 2114, the telescopic end of each second damper 2114 is fixedly connected with a second moving block 2115, the outer surface of each second moving block 2115 is slidably connected with the inside of the transverse shell 2113, and each second damper The outer surface of the device 2114 is sleeved with a second buffer spring 2121, and the two ends of each second buffer spring 2121 are respectively in contact with the inner wall of the transverse shell 2113 and the outer surface of the second moving block 2115, and a second buffer frame 2116 is arranged above each transverse shell 2113, and the bottom surface of each second buffer frame 2116 is fixedly connected to the upper surface of the second moving block 2115, and the inner wall of each second buffer frame 2116 is fixedly connected to a second guide rod 2117, and the outer surface of each second guide rod 2117 is slidably connected to a second connecting block 2118, and the outer surface of each second connecting block 2118 is rotatably connected to the inner wall of the frame 13, and the inner wall of each second connecting block 2118 is fixedly connected to a second wear-resistant damping ring 2119.The inner wall of each second wear-resistant damping ring 2119 contacts the outer surface of the second guide rod 2117, and the outer surface of each second guide rod 2117 is sleeved with two second return springs 2120. The two ends of each second return spring 2120 contact the inner wall of the second buffer frame 2116 and the outer surface of the second connecting block 2118 respectively. The first damper 2102 adopts a customizable non-standard telescopic column damper, which is mainly composed of inner and outer tubes and a piston, and has a damping medium inside. When the telescopic end is extended and retracted by an external force, the piston moves to make the medium flow between the chambers. The resistance generated by the viscosity of the medium and the obstruction of the piston channel slows down the movement speed of the piston and the telescopic end, and finally converts the external mechanical energy into heat energy to achieve buffering and shock absorption. By setting the first damper 2102 and the second A buffer spring 2104 can effectively buffer the up and down sliding of the first moving block 2103 in the vertical shell 2101. The inner wall of the first wear-resistant damping ring 2108 has good viscoelasticity and wear resistance, and the relative movement with the contact object generates friction energy consumption. The viscoelasticity of the material causes the internal loss of vibration energy, the structural deformation consumes energy and generates a restoring force that hinders the movement, and the high-frequency vibration damping effect is stronger. By setting the first wear-resistant damping ring 2108, the relative movement between it and the outer surface of the first guide rod 2106 has a certain damping property, and then cooperates with the resilience of the first return spring 2109 to effectively buffer the movement of the first connecting block 2107 relative to the first guide rod 2106, indicating that the body 11 and the outer shell 12 can follow the rotation of the pillar 15 on the inner ring of the support bearing 14 and move relative to the side. The frame 13 rotates, and when the upper or lower part of the display body 11 is subjected to an external force, the external force is first transmitted to the first connecting block 2107, and the movement of the first wear-resistant damping ring 2108 relative to the first guide rod 2106 and the rebound of the first return spring 2109 can effectively buffer the external force. During this period, the first moving block 2103 will also slide up and down in the vertical shell 2101, and the first damper 2102 and the first buffer spring 2104 can also effectively buffer the sliding of the first moving block 2103, and when the upper or lower part of the display body 11 is about to rotate relative to the frame 13 due to inertia due to the external force exerted on the upper and lower parts of the display body 11 due to other connected structures, the above-mentioned buffering can still take effect, so as to buffer the external force exerted on the upper and lower parts of the display body 11 and reduce the upper and lower parts of the display body 11 due to The relative shaking caused by external force can increase the anti-dumping effect of the buffer display body 11. The second damper 2114 adopts a customizable non-standard telescopic column damper, which is mainly composed of inner and outer tubes and a piston. There is a damping medium inside. When the telescopic end is extended and retracted by external force, the piston moves to make the medium flow between chambers. The resistance generated by the viscosity of the medium and the obstruction of the piston channel slows down the movement speed of the piston and the telescopic end, and finally the external mechanical energy is converted into heat energy to achieve buffering and shock absorption. By setting the second damper 2114 and the second buffer spring 2121, the left and right sliding of the second moving block 2115 in the transverse shell 2113 can be effectively buffered. The inner wall of the second wear-resistant damping ring 2119 has good viscoelasticity and wear resistance, and the relative movement with the contact object generates friction energy consumption.The viscoelasticity of the material causes internal loss of vibration energy, structural deformation consumes energy and generates a restoring force that hinders movement, and has a stronger damping effect on high-frequency vibrations. By setting a second wear-resistant damping ring 2119, its relative movement with the outer surface of the second guide rod 2117 has a certain damping property, and then cooperates with the resilience of the second return spring 2120 to effectively buffer the movement of the second connecting block 2118 relative to the second guide rod 2117. When the left and right parts of the display body 11 or the two side frames 13 are subjected to external force, the external force is first transmitted to the second connecting block 2118, the movement of the second wear-resistant damping ring 2119 relative to the second guide rod 2117 and the rebound of the second return spring 2120 The external force can be effectively buffered, during which the second moving block 2115 will also slide left and right in the transverse shell 2113, and the second damper 2114 and the second buffer spring 2121 can also effectively buffer the sliding of the second moving block 2115, and when the left and right parts of the display body 11 or the two side frames 13 are about to rotate relative to the bottom plate 2112 due to inertia due to the external force exerted on other connected structures, the above buffering can still take effect, playing a role in buffering the external force exerted on the left and right parts of the display body 11 and slowing down the relative shaking of the left and right parts of the display body 11 or the two side frames 13 due to the external force, thereby increasing the buffering effect of the display body 11 against tipping;

[0042] See also Figure 2 and Figure 3 , wherein the inner top walls of the two vertical shells 2101 and the inner bottom walls of the other two vertical shells 2101 are fixedly connected with first buffer rubber blocks 2110, wherein the bottom surfaces of the two first buffer rubber blocks 2110 are respectively in contact with the upper surfaces of the two first moving blocks 2103, and the upper surfaces of the other two first buffer rubber blocks 2110 are respectively in contact with the bottom surfaces of the other two first moving blocks 2103. By setting the first buffer rubber blocks 2110, they themselves have good elasticity, thereby preventing the first moving blocks 2103 from causing rigid collision with the inner wall of the vertical shell 2101 when sliding up and down relative to the vertical shell 2101;

[0043] See also Figure 3 and Figure 4 The front and back sides of each first moving block 2103 are fixedly connected with a first limiting slide post 2111, and the outer surface of each first limiting slide post 2111 is slidably connected with the inside of the vertical shell 2101. By setting the first limiting slide post 2111, it can slide up and down in a directional manner inside the vertical shell 2101, thereby increasing the directional property of the first moving block 2103 sliding up and down in the vertical shell 2101;

[0044] See also Figure 5 and Figure 6The inner side wall of each transverse shell 2113 is fixedly connected with a second buffer rubber block 2122, and the side surfaces of the two second buffer rubber blocks 2122 that are close to each other are in contact with the side surfaces of the two second moving blocks 2115 that are away from each other. By providing the second buffer rubber blocks 2122, they themselves have good elasticity, thereby preventing the second moving blocks 2115 from rigidly colliding with the inner wall of the transverse shell 2113 when sliding left and right relative to the transverse shell 2113;

[0045] See also Figure 6 and Figure 7 The front and back sides of each second moving block 2115 are fixedly connected with a second limiting slide post 2123, and the outer surface of each second limiting slide post 2123 is slidably connected to the inside of the transverse shell 2113. By setting the second limiting slide post 2123, it can slide up and down in a directional manner inside the transverse shell 2113, thereby increasing the directionality of the second moving block 2115 sliding left and right in the transverse shell 2113.

[0046] The specific implementation of this embodiment is as follows: when the upper or lower part of the display body 11 is subjected to external force, the external force is first transmitted to the first connecting block 2107, and since the display body 11 and the housing 12 rotate relative to the frame 13 following the rotation of the support 15 on the inner ring of the support bearing 14, the first moving block 2103 tends to slide up and down in the vertical shell 2101, and then the damping movement of the first wear-resistant damping ring 2108 relative to the first guide rod 2106 and the rebound of the first return spring 2109 effectively buffer the external force. During this period, when the first moving block 2103 has a tendency to slide up and down in the vertical shell 2101, the first damper 2102 and the first buffer spring 2104 effectively buffer the up and down sliding of the first moving block 2103 in the vertical shell 2101, and when the upper or lower part of the display body 11 is about to rotate relative to the frame 13 due to inertia due to external forces exerted on other connected structures, the above-mentioned buffering can still take effect, buffering the external forces exerted on the upper and lower parts of the display body 11 and slowing down the relative shaking of the upper and lower parts of the display body 11 due to external forces. The second movable block 2115 has a tendency to slide left and right in the transverse shell 2113 and slides in the transverse shell 2113. The second damper 2114 and the second buffer spring 2121 effectively buffer the sliding of the second moving block 2115, and when the left and right parts of the display body 11 or the two side frames 13 are about to rotate relative to the bottom plate 2112 due to inertia due to the external force exerted on other connected structures, the above-mentioned buffering can still take effect, buffering the external force exerted on the left and right parts of the display body 11 and reducing the relative shaking of the left and right parts of the display body 11 or the two side frames 13 due to the external force, thereby increasing the buffering effect of the display body 11 to prevent it from tipping over.

It can be connected to the control end of each electrical component through the digital output pin, and the power of each component can be controlled through the analog output pin. The specific control logic and timing are realized by writing code. The inertial detection unit 2208, referred to as IMU, is composed of sensors such as accelerometers, gyroscopes and magnetometers. It is used to measure information such as acceleration, angular velocity and magnetic field of an object, so as to determine the posture and motion state of the object.

[0051] Example 3: Please refer to Figure 1 , Fig.11 , Fig.12 , Fig.13 and Fig.14 The present invention provides a technical solution: a protective device for a digital media display device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0052] As a further limitation of the adaptive support mechanism 3 of the present invention, an adaptive support mechanism 3 is arranged on the outer side of the center of gravity sinking unit 22, and the adaptive support mechanism 3 is used in conjunction with the anti-tilt stabilizing mechanism 2, and the adaptive support mechanism 3 is used for multi-scenario adaptive stabilizing support of structures such as the display body 11 and the anti-tilt stabilizing mechanism 2;

[0053] The adaptive support mechanism 3 includes a cross base 301, the inner wall of the cross base 301 is fixedly connected to the outer surface of the storage shell 2201, the inner wall of the cross base 301 is fixedly connected to four short-distance electric rods 302, the telescopic end of each short-distance electric rod 302 is fixedly connected to a connecting frame 303, the inner wall of each connecting frame 303 is fixedly connected to a support rod 304, a rotating block 305 is arranged inside each connecting frame 303, the inner wall of each rotating block 305 is rotatably connected to the outer surface of the support rod 304, a support block 306 is arranged below each short-distance electric rod 302, the interior of each support block 306 is slidably connected to the outer surface of the rotating block 305, and the bottom surface of each support block 306 is fixedly connected to an elastic anti- The inner bottom wall of each support block 306 is fixedly connected with a pressure sensor 308, and the upper surface of each pressure sensor 308 is in contact with the bottom surface of the rotating block 305. The four short-distance electric rods 302 and the four pressure sensors 308 are electrically connected to the button controller 2206 through wires. By setting the short-distance electric rod 302, the extension of the short-distance electric rod 302 after power-on can control the distance between the support block 306 and the elastic anti-skid pad 307 and the ground. The rotating block 305 can rotate around the outer surface of the support rod 304, thereby improving the support flexibility of the support block 306, and the rotating block 305 can slide up and down inside the support block 306, so that the support block 306 and the elastic anti-skid pad 307 can be used to adjust the uneven ground. When the support is stable, the four short-distance electric rods 302 can be powered on and extended to different lengths after operating the button controller 2206. Since the rotating block 305 can slide to different depths of the supporting block 306 and generate different pressures on the pressure sensor 308, when the four pressure sensors 308 are subjected to the same pressure from the upper rotating block 305 and the inertia detection unit 2208 detects that the display body 11 is stably upright, the button controller 2206 can control the four short-distance electric rods 302 to stop extending and retracting and maintain their respective extended states. When the display body 11 is obviously tilted due to external force, the inertia detection unit 2208 can detect the change in the tilt angle of the display body 11 and the change in acceleration during the tilt process. The posture changes, and the tilt of the display body 11 will also cause the overall center of gravity of the device to change, and then the pressure from the rotating block 305 felt by the four pressure sensors 308 will change. The button controller 2206 can calculate and control one or more short-distance electric rods 302 to extend and retract to different lengths by analyzing the posture change parameters of the display body 11 detected by the inertia detection unit 2208 and the changes in the pressure from the rotating block 305 felt by the four pressure sensors 308, until the extension and retraction can effectively compensate for the tilt change of the display body 11, and finally make the four pressure sensors 308 feel the same pressure from the rotating block 305 and the inertia detection unit 2208 detects that the posture of the display body 11 is stably upright.The button controller 2206 can control the four short-distance electric rods 302 to stop extending and retracting and maintain the corresponding extension state, which greatly increases the anti-tilting property of the display body 11 on uneven ground, and when the display body 11 is subjected to external force, it can effectively resist the external force and increase the anti-tilting property of the display body 11;

[0054] See also Figure 1 and Fig.11 The bottom surface of the cross base 301 is fixedly connected with four connecting columns 309, and the bottom end of each connecting column 309 is fixedly connected with a universal wheel 310. By providing the connecting columns 309, the universal wheel 310 can be connected to the bottom of the cross base 301, so that when the support block 306 and the elastic anti-skid pad 307 are not in contact with the ground, the stability of the display body 11 during movement can be increased, thereby increasing the anti-dumping property of the display body 11 during movement;

[0055] See also Fig.12 and Fig.13 The outer surface of the telescopic end of each short-span electric rod 302 is fixedly connected with a reinforcement ring 311, and the bottom surface of each reinforcement ring 311 is fixedly connected to the upper surface of the connecting frame 303. By setting the reinforcement ring 311, the connection between the telescopic end of the short-span electric rod 302 and the connecting frame 303 can be reinforced, thereby increasing the connection strength between the two, thereby improving the reliability of stable support of the adaptive support mechanism 3.

[0056] The specific implementation of this embodiment is as follows: when the support block 306 and the elastic anti-skid pad 307 are needed to stably support the uneven ground, the button controller 2206 is operated to make the four short-distance electric rods 302 powered on respectively and extend and retract to different lengths. When the four pressure sensors 308 are subjected to the same pressure from the upper rotating block 305 and the inertia detection unit 2208 detects that the display body 11 is stably upright, the button controller 2206 controls the four short-distance electric rods 302 to stop extending and retracting respectively and maintain their respective extended and retracted states, so as to achieve the effect of adaptively and stably supporting the uneven ground. When the display body 11 is obviously tilted due to external force, the inertia detection unit 2208 detects the change in the tilt angle of the display body 11 and the change in the posture caused by the change in acceleration during the tilt process. In addition, the tilt of the display body 11 will also cause the overall center of gravity of the device to change, and thus the four pressure sensors 3 08 senses that the pressure from the rotating block 305 will change, and the button controller 2206 calculates and controls one or more short-distance electric rods 302 to extend and retract to different lengths by analyzing the posture change parameters of the display body 11 detected by the inertia detection unit 2208 and the changes in the pressure from the rotating block 305 sensed by the four pressure sensors 308, until the extension and retraction effectively compensates for the tilt change of the display body 11, and finally makes the four pressure sensors 308 feel the same pressure from the rotating block 305 and the inertia detection unit 2208 detects that the posture of the display body 11 is stably upright, and the button controller 2206 controls the four short-distance electric rods 302 to stop extending and retracting and maintain the corresponding extension and retraction states, which greatly increases the anti-tipping ability of the display body 11 on uneven ground, and the display body 11 can effectively resist the external force after being subjected to the external force, thereby increasing the anti-tipping ability of the display body 11.
