Figure 6 It is a schematic view of the rear shell of the utility model clamped on the first frame of the front shell. Figure 7 It is a schematic view of the rear shell of the utility model after clamping on the first frame of the front shell.

[0098] Referring to Figures 2 to 7 , the rear shell 300 is arranged on the rear side of the back plate 100, and the rear shell 300 can include a rear plate 310 which is a plate structure; the plane where the rear plate 310 is located is parallel to the back surface of the back plate 100. The rear plate 310 is a flat plate structure, the structure of the rear plate 310 is simple, and the rear plate 310 is convenient to process and manufacture.

[0099] In some embodiments, the rear shell 300 is a glass fiber plate. In other embodiments, the rear shell 300 is a plastic plate.

[0100] In some embodiments, the rear shell 300 further comprises a skeleton 320 which is attached to and fixed on the side of the rear plate 310 facing the back plate 100; the skeleton 320 extends from one edge of the rear plate 310 to form a limiting portion 321. The limiting portion 321 can be inserted into and engaged in the clamping groove 215 of the first frame 210 to limit the movement of the skeleton 320 in the front-rear direction.

[0101] In one embodiment, the first frame 210 is arranged on the top side of the back plate 100, and the limiting portion 321 is correspondingly arranged on the top side of the rear shell 300. In another embodiment, the first frame 210 is arranged on the left and right sides or the bottom side of the back plate 100, and the limiting portion 321 is correspondingly protruded from the left and right sides or the bottom side of the rear shell 300.

[0102] In some embodiments, the skeleton 320 is formed with protruding support ribs 322 facing the back plate 100. When the limiting portion 321 is inserted into the clamping groove 215, one end of the support rib 322 facing the back plate 100 abuts against the back plate 100 or the rear shell 300. The front end of the support rib 322 abuts against the second clamping plate 213, and the rear end of the limiting portion 321 abuts against the side wall of the clamping groove 215, thereby limiting the movement of the rear plate 310 in the front-rear direction on the side where the limiting portion 321 is arranged.

[0103] The support ribs 322 are arranged at intervals. In one embodiment, the limiting portion 321 is arranged on the top edge of the rear shell 300, and the support ribs are arranged at intervals in the vertical direction.

[0104] In some embodiments, the skeleton 320 is formed with abutting ribs 323 facing the back plate 100, which abut against the back of the back plate 100. This can effectively avoid the rear plate 310 forming a convex structure facing the back plate 100, thereby maintaining the shape of the rear shell 300. It can also effectively prevent the rear shell 300 from pressing the electronic components on the back of the back plate 100.

[0105] The skeleton 320 comprises a plurality of reinforcing beams extending in the horizontal and vertical directions respectively; the reinforcing beams are glued to the side of the rear plate 310 facing the back plate 100; at least one reinforcing beam extends from the top edge of the rear plate 310 to form the limiting portion 321. Specifically, the reinforcing beams on the top side of the rear shell 300 protrude upward from the top side of the rear shell 300 to form the limiting portion 321.

[0106] The planar structure on the rear side of the reinforcing beam is connected to the side of the rear plate 310 facing the back of the back plate 100 by gluing. The back plate 310 does not need to be designed or processed with a separate connecting structure to connect the reinforcing beam, so as to ensure that the structure of the back plate 310 is simple and the manufacturing of the rear shell 300 is convenient.

[0107] In some embodiments, the reinforcing beams are connected to one side of the back plate 310 facing the back plate 100 by fasteners such as bolts, screws or rivets. No complex matching structure for connecting the reinforcing beams needs to be processed on the back plate 310.

[0108] Part or all of the reinforcing beams are provided with reinforcing channels, and reinforcing rods 324 are arranged in the reinforcing channels. The reinforcing rods 324 are in transition fit or interference fit with the reinforcing channels, and the arrangement of the reinforcing rods 324 in the reinforcing beams enhances the structural strength of the back shell 300.

[0109] Figure 8 is a schematic view of the installation of the clamping piece on the back shell on the second frame in the utility model. Figure 9 is a schematic view of the installation of the clamping piece on the back shell 300 on the second frame after the installation of the clamping piece on the back shell in the utility model.

[0110] Referring to Figure 8 and Figure 9 , the back shell 300 can include a clamping piece 330 which is attached to and fixed on one side of the back plate 310 facing the back plate 100. The clamping piece 330 includes a base and an elastic clamping hook 331 formed on the base and protruding towards the back plate 100. The elastic clamping hook 331 is detachably clamped on the clamping structure 223.

[0111] The front shell 200 includes a first frame 210 and a second frame 220, and the first frame 210 and the second frame 220 respectively extend beyond the back surface of the back plate 100. The first frame 210 is formed with a clamping groove 215 opening towards the center of the back plate 100 on the back surface of the back plate 100. The second frame 220 is formed with a clamping structure 223 towards the center of the back plate 100 on the back surface of the back plate 100. The back shell 300 is a split structure composed of a back plate 310, a skeleton 320 and a clamping piece 330. The limiting part 321 on the skeleton 320 is limited in the clamping groove 215, and the elastic clamping hook 331 on the clamping piece 330 is clamped on the clamping structure 223, so as to fix the back shell 300 on the back surface of the back plate 100. At the same time, the back shell 300 is a split structure composed of the back plate 310, the skeleton 320 and the clamping piece 330, and the single components can be designed and manufactured respectively, so that the structure of the single components is simpler and more convenient for design and processing, thereby reducing the production cost. At the same time, the fixation of the back shell 300 on the back surface of the back plate 100 reduces the use of screws.

[0112] When the back shell 300 is installed, the limiting part 321 on the back shell 300 is inserted into the clamping groove 215, and then the back shell 300 is pressed forward relative to the back plate 100, so that the elastic clamping hook 331 is clamped on the corresponding clamping structure 223, thereby facilitating the quick installation of the back shell 300 on the back plate 100.

[0113] The engaging member 330 of the rear shell 300 is formed with a front protruding elastic hook 331; the elastic hook 331 can be elastically deformed to be detachably engaged on the engaging structure 223 on the second frame 220 of the front shell 200. By the engagement of the elastic hook 331 and the engaging structure 223 on the front shell 200, the movement of the second frame 220 of the rear shell 300 relative to the back plate 100 in the front-rear direction is limited, avoiding the deformation and cracking of the second frame 220 of the rear shell 300 on the prior device.

[0114] The engaging structure 223 is formed at the inner end of the extension arm 222 at the second frame 220 of the front shell 200, and the elastic hook 331 is engaged on the inner end of the extension arm 222. The outer side of the front end of the elastic hook 331 is an inclined guide slope 332 in the front-rear direction, and the inner side of the guide portion 224 on the extension arm 222 is an outwardly inclined guide slope 225 in the front-rear direction, and the guide slope 332 and the guide slope 225 are matched. When the elastic hook 331 is engaged on the inner end of the extension arm 222 from rear to front, the guide slope 332 and the guide slope 225 are in contact and guided, so that the extension arm 222 is elastically deformed forward, and the elastic hook 331 is elastically deformed inward. After reaching the preset position, the extension arm 222 and the elastic hook 331 recover the deformation, so that the elastic hook 331 is lapped on the front side of the extension arm 222, and the movement of the engaging member 330 rearward is limited.

[0115] The elastic hook 331 includes an extension section 333 and a hook section 334 bent from the extension section 333 and extending outward; the hook section 334 is used to lap on the front side of the extension arm 222. The guide slope 332 is provided on the outer end of the hook section 334. The rear side of the hook section 334 is lapped on the front side of the extension arm 222, and the outer side of the extension section 333 abuts against the inner end of the extension arm 222.

[0116] It should be noted that when the guide slope 332 on the elastic hook 331 and the guide slope 225 on the front shell 200 are in contact and guided, the elastic hook 331 is elastically deformed inward, and the rear shell 300 also bends to some extent to conform to the deformation of the elastic hook 331 to some extent, avoiding the deformation of the elastic hook 331 relative to the rear shell 300 being too large, effectively avoiding the elastic hook 331 from being broken relative to the engaging member 330.

[0117] The inner side of the extension section 333 and the front side of the rear shell 300 are formed with a reinforcing rib 335 connecting the extension section 333 and the engaging member 330, and the reinforcing rib 335 is provided to enhance the structural strength of the elastic hook 331, effectively avoiding the deformation of the elastic hook 331 being too large, and avoiding the elastic hook 331 from being broken.

[0118] It should be noted that the rear end of the second extension plate 221 is formed with a lap joint portion 226; the rear end of the lap joint portion 226 is formed with a step 227; the upper side edge of the rear shell 300 is lapped on the step surface, limiting the movement of the corresponding edge of the rear shell 300 forward. Specifically, the engaging member 330 is arranged close to the left and right sides of the rear shell 300. The rear plate 310 on the left and right sides of the rear shell 300 exceeds the engaging member 330 in the left and right directions, and the left and right edges of the rear plate 310 are lapped on the step surface in front, so that the rear shell 300 has a smaller thickness on the basis of ensuring the lapping of the rear shell 300, so that the display device has a smaller thickness in the front and rear directions. The cooperation of the elastic clamping hook 331 and the extension arm 222 limits the rearward movement of the rear shell 300, and the cooperation of the rear plate 310 and the step surface limits the forward movement of the rear shell 300.

[0119] In some embodiments, the engaging member 330 is a sheet structure, and the side of the engaging member 330 away from the back is glued to the side of the rear plate 310 facing the back. The sheet structure of the engaging member 330 makes the side of the engaging member 330 lapped on the side of the rear shell 300 a planar structure. The planar structure on the rear side of the engaging member 330 is connected to the side of the rear plate 310 facing the back by gluing. The rear plate 310 does not need to design or process a separate connecting structure corresponding to the engaging member 330, so as to ensure that the structure of the rear plate 310 is simple and the manufacturing of the rear shell 300 is convenient.

[0120] In some embodiments, the rear shell 300 is connected to the side of the rear plate 310 facing the back plate 100 by fasteners such as bolts, screws or rivets. The rear plate 310 also does not need to process a complex matching structure for connecting the engaging member 330.

[0121] In some embodiments, the engaging member 330 is arranged close to the left and right sides of the rear plate 310, and the engaging member 330 is arranged with the engaging member 330 on the left and right sides of the rear plate 310, respectively.

[0122] In some embodiments, the first frame 210 is arranged on the top side of the back plate 100; and the two second frames 220 are arranged on the left and right sides of the back plate 100, respectively.

[0123] After the limiting portion 321 extends into the clamping groove 215 of the first frame 210 on the top side of the back plate 100, the rear shell 300 is pressed forward relative to the back plate 100, so that the elastic clamping hook 331 on the engaging member 330 is lapped on the corresponding clamping structure 223. The back plate 100 is provided with the second frame 220 on the left and right sides, so that the rearward movement of the rear shell 300 relative to the back plate 100 is limited by the lapping of the elastic clamping hook 331 on the engaging member 330 on the left and right sides of the back plate 310 on the clamping structure 223. The cooperation of the clamping structure 223 on the left and right sides of the back plate 100 and the elastic clamping hook 331 on the left and right sides of the rear shell 300 limits the left and right sides of the rear shell 300.

[0124] Meanwhile, when the rear shell 300 is installed, the upper end of the rear shell 300 is inserted into the rear plate 100, and then the rear shell 300 is pressed against the rear plate 100, so that the elastic clamping hook 331 is clamped on the clamping structure 223, thereby facilitating the quick installation of the rear shell 300.

[0125] Figure 10 is a sectional view of part of the utility model. Figure 11 is a sectional view of the limiting piece of the utility model.

[0126] Referring to Figure 5 , Figure 10 and Figure 11 , the rear plate 100 is provided with a magnetic part; the rear plate 310 is provided with a fixing structure 400 on the side facing the rear plate 100; the fixing structure 400 is fixed with a magnetic attraction piece 500; the magnetic attraction piece 500 can be magnetically attracted to the magnetic part. Through the magnetic attraction between the magnetic attraction piece 500 and the magnetic part, the attraction force of the rear plate 310 towards the rear plate 100 is provided, effectively avoiding the formation of a convex structure of the rear plate 310 away from the rear plate 100.

[0127] In one embodiment, the rear plate 100 is made of iron material. The magnetic attraction piece 500 is a magnet, and the magnet and the iron rear plate 100 can generate an attractive force.

[0128] In another embodiment, the rear plate 100 is made of any material. The magnetic part is an iron sheet or a magnet separately provided on the rear plate 100, and the magnetic attraction piece 500 is a magnet.

[0129] In some embodiments, the fixing structure 400 includes a fixing piece 410 and a limiting piece 420; the fixing piece 410 is fixed on the side of the rear plate 310 facing the rear plate 100; the fixing piece 410 is provided with a containing groove 411, and the side walls of the containing groove 411 are close to each other in the direction facing the rear plate 100; the limiting piece 420 is arranged in the containing groove 411; the magnetic attraction piece 500 is fixed on the end of the limiting piece 420 facing the rear plate 100; the end of the limiting piece 420 away from the rear plate 100 abuts against the bottom wall of the containing groove 411 or the rear plate 310; the outer periphery of the limiting piece 420 abuts against the side walls of the containing groove 411, and the limiting piece 420 is a structure capable of elastic deformation. When the rear plate 310 is deformed due to heat, the deformation of the rear plate 310 is transmitted to the end of the limiting piece 420 away from the rear plate 100 through the fixing piece 410, which presses the end of the limiting piece 420 away from the rear plate 100 and drives the limiting piece 420 to elastically deform, so that the limiting piece 420 moves along the side walls of the containing groove 411 towards the rear plate 100, thereby maintaining the attractive force between the magnetic attraction piece 500 and the magnetic part.

[0130] The fixing structure 400 is adhered to the rear plate 310 toward the back plate 100. Specifically, the fixing member 410 is adhered to the rear plate 310.

[0131] In one embodiment, the accommodating groove 411 is through the fixing member 410 along the front and back, and the limiting member 420 is arranged in the accommodating groove 411, and one end of the limiting member 420 toward the rear plate 310 abuts against the rear plate 310.

[0132] The limiting member 420 is provided with a limiting groove 421 on the side toward the back plate 100, and the magnetic attraction member 500 is arranged in the limiting groove 421. The magnetic attraction member 500 is adhered or clamped in the limiting groove 421.

[0133] In some embodiments, the limiting member 420 comprises a circumferential wall 422 and a flange 423; the circumferential wall 422 is annular structure; the circumferential wall 422 extends along a plane perpendicular to the rear plate 310; the magnetic attraction member 500 is fixed to one end of the circumferential wall 422 toward the back plate 100; the flange 423 is formed by protruding outward from the outer periphery of the circumferential wall 422; the flange 423 is arranged at one end of the circumferential wall 422 toward the rear plate 310; the accommodating groove 411 is circular in radial cross-section, and the flange 423 abuts against the circumferential wall of the accommodating groove 411.

[0134] The flange 423 is on the outer periphery of the circumferential wall 422, and the circumferential wall 422 is annular structure, so that the circumferential wall 422 can be more easily elastically deformed along its radial direction. When the rear plate 310 is deformed by heat, the rear plate 310 presses the limiting member 420, and the circumferential wall 422 can be elastically deformed to press the limiting member 420 to move along the side wall of the accommodating groove 411 toward the back plate 100, thereby maintaining the attractive force between the magnetic attraction member 500 and the magnetic part.

[0135] The circumferential wall 422 is annular structure, and the circumferential wall 422 forms a cavity 424 at one end toward the rear plate 310. When the projection of the deformed part of the rear plate 310 and the fixing plate is located in the cavity 424, the impact on the limiting member 420 is less, and the impact on the position of the magnetic attraction member 500 is more effectively avoided.

[0136] The flange 423 or the circumferential wall 422 is formed with a protruding abutting protrusion 425 at one end toward the rear plate 310; the abutting protrusion 425 abuts against the bottom wall of the accommodating groove 411 or the rear plate 310; the abutting protrusion 425 is provided with a plurality of abutting protrusions 425 which are spaced apart around the axis of the circumferential wall 422.

[0137] The abutting protrusions 425 are spaced apart. When the deformed position of the rear plate 310 or the fixing member 410 is between the spaces of the abutting protrusions 425, the impact of the deformation of the rear plate 310 on the limiting member 420 is effectively reduced, thereby reducing the impact on the position of the magnetic attraction member 500.

[0138] The accommodating groove 411 is inwardly protruded at one end of the back plate 100 to form a ring protrusion 412; the flange 423 is projected to fall on the ring protrusion 412. When the limiting piece 420 moves to the preset position towards the back plate 100, the ring protrusion 412 can stop the flange 423, so as to more effectively avoid the limiting piece 420 from being taken out of the accommodating groove 411.

[0139] In one embodiment, the framework 320, the clamping piece 330 and the fixing piece 410 are all fixed on the front side of the back plate 310 towards the back plate 100 by pasting. Compared with the prior art in which the back shell 300 is a whole structure, the front side of the back plate 310 is provided with the framework 320, so that the thickness of the back plate 310 is set to be thinner.

[0140] The framework 320, the clamping piece 330 and the fixing piece 410 are all fixed on the back plate 310 by pasting, so as to facilitate the separate design and manufacture of the framework 320, the clamping piece 330 and the fixing piece 410 on the basis of ensuring the thickness of the back shell 300.
