[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a collision-resistant LED backlight protection structure, which has the following beneficial effects:
[0018] 1. This anti-collision LED backlight protection structure, when the elastic plate undergoes elastic deformation, the contact surface between the damping coating and the arc-shaped slide rail is tightened. This allows the movement of the conical pulley to have a certain damping effect. This ensures that when the LED backlight is protected by the protective component, only slight shaking occurs, which can offset the impact force generated by the collision. Thus, the LED backlight can be effectively protected, avoiding the problems of traditional LED backlight structures that lack a buffer protection structure. When damaged during transportation and use, the device cannot absorb energy on its own, and the internal electronic components are fragile and easily damaged, affecting the service life.
[0019] 2. The anti-collision LED backlight protection structure can bear part of the impact force when the LED backlight is subjected to an impact or collision. In addition, the silicone anti-collision strip can make contact with the object being collided with first when the LED backlight falls or collides. As a result, the silicone anti-collision strip will undergo elastic deformation, thereby offsetting part of the force. Attached Figure Description

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0028] Please see Figure 1-3 This utility model provides a new technical solution: a collision-proof LED backlight protection structure, including an LED backlight 1 and a protective shell 3. An inner mounting frame 2 is fixedly connected to the outer surface of the LED backlight 1, and multiple protective components are provided on the protective shell 3. The multiple protective components are evenly arranged in a circumferential array.
[0029] The protective assembly is used to protect the LED backlight 1. The protective assembly includes a first fixed post 4, an elastic plate 6, a movable sleeve 7, a movable post 8, a conical pulley 10, a spring 12, and a damping coating 16.
[0030] The first fixing post 4 in the protective assembly is fixedly connected to the outer surface of the inner mounting frame 2, and a fixing sleeve 5 is fixedly sleeved on the outer surface of the first fixing post 4. The elastic plate 6 is fixedly connected to the outer surface of the fixing sleeve 5.
[0031] The movable sleeve 7 is fixedly connected to the end of the elastic plate 6 away from the fixed sleeve 5. The two ends of the elastic plate 6 are staggered in a horizontal and vertical state. The elastic plate 6 has a certain elastic deformation capacity in both horizontal and vertical states. The movable column 8 is slidably connected inside the movable sleeve 7.
[0032] Furthermore, two arc-shaped slide rails 11 are fixedly connected to the outer surface of the inner mounting frame 2, and a tapered pulley 10 is slidably connected between the two arc-shaped slide rails 11.
[0033] Furthermore, a damping coating 16 is applied to the conical surface where the conical pulley 10 contacts the two arc-shaped slide rails 11, and the conical pulley 10 is fixedly connected to the movable column 8.
[0034] Furthermore, a slider 9 is fixedly connected to the end of the movable column 8 away from the conical pulley 10, and a spring 12 is sleeved on the outer surface of the movable column 8, with the spring 12 located between the slider 9 and the movable sleeve 7.
[0035] Furthermore, the inner wall of the protective shell 3 is provided with a groove 13, and the slider 9 is slidably connected in the groove 13. Silicone anti-collision strips 15 are fixedly connected at the four corners of the protective shell 3. The silicone anti-collision strips 15 are used to protect the LED backlight 1.
[0036] Furthermore, two dustproof rubber sheets 14 are fixedly connected between the inner mounting frame 2 and the protective shell 3 for dust protection.
[0037] Furthermore, when the LED backlight 1 is subjected to impact or collision during use, the protective shell 3 can bear part of the impact force, and the silicone anti-collision strip 15 can make contact with the object being collided with first when the LED backlight 1 falls or collides, so that the silicone anti-collision strip 15 will undergo elastic deformation, thereby offsetting part of the force.
[0038] Furthermore, when the protective shell 3 is impacted by external forces, the force is transmitted into the LED backlight 1. Under inertial force, the LED backlight 1 and the inner mounting frame 2 will undergo a certain degree of displacement or rotation. When the inner mounting frame 2 is displaced and rotated, the elastic plate 6 and spring 12 in the multiple protective components will undergo elastic deformation, thereby driving the movable column 8 and the conical pulley 10 to move up and down under the constraint of the two arc-shaped slide rails 11. When the elastic plate 6 undergoes elastic deformation, the contact surface between the damping coating 16 and the arc-shaped slide rail 11 will be tightened. This allows the movement of the conical pulley 10 to have a certain damping effect. This allows the LED backlight 1 to only experience slight shaking when protected by the protective components, which can offset the impact force generated by the collision. Thus, the LED backlight 1 can be effectively protected, avoiding the problems of traditional LED backlight structures lacking buffer protection structures, which cannot absorb energy during transportation and use, and whose internal electronic components are fragile and easily damaged, affecting their service life.
[0039] Working principle: When the LED backlight 1 is subjected to impact or collision, the protective shell 3 can bear part of the impact force. The silicone anti-collision strip 15 can make contact with the object being collided with first when the LED backlight 1 falls or collides. As a result, the silicone anti-collision strip 15 will undergo elastic deformation, thereby offsetting part of the force.
[0040] Furthermore, when the protective shell 3 is impacted by the outside, the force is transmitted into the LED backlight 1. Under the inertial force, the LED backlight 1 and the inner mounting frame 2 will undergo a certain degree of displacement or rotation. When the inner mounting frame 2 is displaced and rotated, the elastic plate 6 and spring 12 in the multiple protective components will undergo elastic deformation, thereby driving the movable column 8 and the conical pulley 10 to move up and down under the restriction of the two arc-shaped slide rails 11. When the elastic plate 6 undergoes elastic deformation, the contact surface between the damping coating 16 and the arc-shaped slide rail 11 will be tightened. This allows the movement of the conical pulley 10 to have a certain damping effect. This allows the LED backlight 1 to only produce slight shaking when protected by the protective components, which can offset the impact force generated by the collision.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
