DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The curved focusing TV back panel assembly with adjustable curvature provides two technical solutions:

[0025] like Figure 1-3 The first embodiment is shown: it includes an outer frame 1 and a backlight assembly 2, and the backlight assembly 2 is installed inside the outer frame 1, and a plurality of light panels 3 are arranged on the backlight assembly 2. An adjustment mechanism 4 for adjusting the overall curvature of the outer frame 1 and the backlight assembly 2 is arranged at the rear of the outer frame 1;

[0026] The adjustment mechanism 4 includes a slide rail 41, and a screw rod 42 is rotatably connected between the top and bottom of the inner wall of the slide rail 41. The surface of the screw rod 42 located inside the slide rail 41 is threadedly connected with two upper and lower sliders 43. The left and right sides of the two sliders 43 are fixedly connected with a first ball head seat 44. The back of the outer frame 1 is fixedly connected with two left and right groups of second ball head seats 45, and the two groups of second ball head seats 45 are composed of two upper and lower second ball head seats 45. The screw rod 42 penetrates the slide rail 41 and extends to the bottom of the slide rail 41. The end of the screw rod 42 located below the slide rail 41 is fixedly connected with a handle.

[0027] The adjustment mechanism 4 also includes four groups of push rod assemblies 46, and the four push rod assemblies 46 are respectively located between the four opposite first ball head seats 44 and the four second ball head seats 45. The push rod assemblies 46 are used to push the outer frame 1 and the backlight assembly 2 to change the curvature. A single push rod assembly 46 includes two left and right ball heads 461. The opposite sides of the two ball heads 461 are fixedly connected with a sleeve rod 462. The two ball heads 461 are respectively installed in the inside of the opposite first ball head seat 44 and the second ball head seat 45. A push rod 463 is arranged between the two sleeve rods 462, and the two ends of the push rod 463 are respectively inserted into the inside of the two sleeve rods 462. The outer surface of the sleeve rod 462 is threadedly connected with a hexagon socket bolt 464, and the hexagon socket bolt 464 penetrates into the inside of the sleeve rod 462 to lock the position of the push rod 463.

[0028] The slide rail 41 is fixed to the back of the outer frame 1 through four mounting components 47, and each second ball head seat 45 is fixed to the back of the outer frame 1 through two upper and lower mounting components 47. The mounting component 47 consists of a mounting plate 471, a bolt head 472 and a nut 473. The mounting plate 471 is fixed on the second ball head seat 45, and during installation, the ball head 461 is sleeved on the sleeve rod 462 and locked by the nut 473.

[0029] The curvature of the backlight assembly 2 is adjusted by a newly designed adjustment mechanism 4. The adjustment mechanism 4 has a simple structure and occupies a small volume, and can be suitable for ultra-thin TVs. Moreover, the adjustment mechanism 4 as a whole can be spliced ​​and the whole can be quickly installed on the outer frame 1, thereby improving the practicability of the device when in use.

[0030] like Figure 1 and 4 A second embodiment is shown, the main difference from the first embodiment is that a reflector 5 is fixedly connected to the front side of the backlight assembly 2, and the reflector 5 is a hollow quadrangular pyramid, a plurality of second through grooves 51 are equidistantly provided on the top and bottom of the reflector 5, and a plurality of first through grooves 11 are equidistantly provided on the front and back sides of the outer frame 1.

[0031] Through grooves are provided on the outer frame 1 and the reflective member 5 so that the outer frame 1 and the reflective member 5 can better adapt to each other when they are bent, which is beneficial to the long-term use of the backlight assembly.

[0032] During installation, first install the two ball heads 461 into the second ball head seat 45, and then put the two mounting plates 471 on the second ball head seat 45 onto the bolt heads 472 at the corresponding positions, and tighten them with nuts 473. At the same time, the slide rail 41 is fixed to the back of the outer frame 1 in the same way. Then, insert one end of the push rod 463 into the sleeve rod 462, and align the other end of the push rod 463 with the relative sleeve rod 462, and move the push rod 463 so that the other end of the push rod 463 also enters the relative sleeve rod 462. Finally, tighten the hexagon socket bolt 464 to lock the position of the push rod 463. During adjustment, rotate the screw rod 42 by turning the handle. The rotation of the screw rod 42 causes the slider 43 to move downward, thereby reducing the distance between the first ball head seat 44 and the second ball head seat 45, thereby increasing the curvature of the outer frame 1, and vice versa.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
