Description

Technical Field

[0001] The present invention relates to the technical field of display assembly, and particularly to a magnetic adsorption structure for a display. Background Art

[0002] In the traditional display assembly process, mechanical connection methods such as screws and buckles are usually used to fix the front frame, rear cover, and display screen. These traditional connection methods have the following problems:

[0003] Complex assembly: Screw connection requires tools such as screwdrivers to tighten the screws one by one, with cumbersome operations and long time consumption, reducing production efficiency. Although buckle connection does not require tools, the installation and disassembly of buckles require certain skills and force, and it is easy to have situations where the buckles are damaged or not installed in place, increasing the assembly difficulty.

[0004] Difficult disassembly: When disassembling screw connection, the screws need to be loosened one by one. Once the screws rust or become stripped, the disassembly will become very difficult. After multiple disassembly and assembly operations of buckle connection, the elasticity of the buckles may weaken, resulting in inability to be properly clamped, and even may damage the components, affecting the service life of the display.

[0005] High risk of component damage: During the installation and disassembly process, screws or buckles may cause damage such as scratches and deformations to the components of the display. Especially for some precision electronic components and appearance components, such damage may affect the performance and appearance quality of the display.

[0006] High requirements for production process: In order to achieve the connection of screws or buckles, the tightening torque of screws or the installation position of buckles needs to be precisely controlled during the production process, with high requirements for the production process. Otherwise, quality problems are likely to occur.

[0007] Increased materials and costs: Connectors such as screws, nuts, and buckles themselves require additional material costs, and additional processes are needed to install these connectors during the production process, increasing production costs and management difficulties.

[0008] With the continuous development of technology and the increasing requirements of consumers for product convenience and aesthetics, the traditional display assembly method has been difficult to meet the needs of modern display production. Therefore, developing a new display assembly structure to simplify the assembly process, improve the disassembly convenience, reduce the risk of component damage, and reduce the complexity and cost of the production process has become an urgent problem to be solved in the display field.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment 1:

[0047] Referring to the attached Figures 1 - 11 , a magnetic attraction structure of a display, including an adsorption mechanism arranged inside the display. The display includes a front frame 100, a rear cover 200 and a display screen 300. The adsorption mechanism is used to assemble the front frame 100, the rear cover 200 and the display screen 300. The adsorption mechanism includes a magnetic attraction assembly 1 for assembling the front frame 100 and the display screen 300 and several installation assemblies 2 for assembling the rear cover 200 and the display screen 300;

[0048] Through the setting of the magnetic attraction assembly 1, it is used to assemble the front frame 100 and the display screen 300 by magnetic attraction, and through the setting of the installation assembly 2, it is used to assemble the display screen 300 and the rear cover 200 by magnetic attraction and fixation;

[0049] The magnetic attraction assembly 1 includes a connecting plate 11 fixed inside the front frame 100 and four L-shaped corner blocks 12 fixed on the inner side of the display screen 300. A magnetic attraction locking part is arranged on the connecting plate 11 for locking the four L-shaped corner blocks 12;

[0050] The magnetic attraction component 1 includes an L-shaped corner block 12 fixed to the inner side of the display screen 300 and a magnetic attraction locking member disposed inside the front frame 100. By providing the magnetic attraction locking member, the L-shaped corner block 12 can be locked by magnetic attraction, thereby forming the magnetic attraction installation work of the display screen 300 and the front frame 100. The magnetic attraction connection method does not require complex screw or buckle operations. The magnetic attraction connection is easy to disassemble, will not damage the components, the assembly process is simple and fast, does not require structures such as screw posts, reduces the requirements for component molds and production processes, and reduces the material and process costs required by the traditional connection method.

[0051] Refer to the appendix Figures 4 to 6 The magnetic attraction locking member includes two U-shaped rods 13 slidably connected to the connecting plate 11 and a driving member 15 for driving the two U-shaped rods 13 to approach or separate from each other. L-shaped locking blocks 14 are fixedly connected to both ends of the two U-shaped rods 13.

[0052] By providing the driving member 15, it is used to drive the two U-shaped rods 13 in the direction of approaching or separating from each other. Through the movement of the two U-shaped rods 13 in the separating direction, the two groups of L-shaped locking blocks 14 can be driven to move away from each other, and then can be inserted into the L-shaped corner block 12 at the corresponding position to form a locking operation, realizing the installation of the front frame 100 and the rear cover 200.

[0053] Refer to the appendix Figure 6 and Figure 7 The driving member 15 includes two sliding blocks 151 slidably connected to the connecting plate 11. Both of the two sliding blocks 151 are fixedly connected to the two U-shaped rods 13 through guide rods 152 respectively.

[0054] By fixedly connecting the sliding block 151 to the U-shaped rod 13 through the guide rod 152, the movement of the sliding block 151 left and right can drive the U-shaped rod 13 to move left and right through the guide rod 152, and then drive the two L-shaped locking blocks 14 to move left and right, forming the detachable installation work of the display screen 300 and the front frame 100.

[0055] An L-shaped rod 153 is rotatably connected to the connecting plate 11, and a main magnet block 154 is fixedly connected to the outer surface of the L-shaped rod 153.

[0056] By the rotational installation of the L-shaped rod 153 and fixedly connecting the main magnet block 154 to the outer surface of the L-shaped rod 153, it is convenient to drive the main magnet block 154 to rotate through the rotation drive of the L-shaped rod 153, realizing the selective adsorption work of the main magnet block 154 on the two sliding blocks 151.

[0057] Refer to the appendix Figure 7, tension springs 155 are sleeved on both of the two guide rods 152, and the two tension springs 155 are used to drive the two sliding blocks 151 away from each other. Both of the two sliding blocks 151 are made of a metal material that can be adsorbed by the main magnet block 154;

[0058] By installing tension springs 155 on both of the two guide rods 152, when the main magnet block 154 rotates to adsorb the two sliding blocks 151, the tension springs 155 are in a stretched state, and then the two U-shaped rods 13 are in a retracted state, that is, the buckle installation function is lost; on the contrary, when the main magnet block 154 rotates to lose the adsorption of the two sliding blocks 151, through the pulling force of the tension springs 155 themselves, the two sliding blocks 151 can be driven to move away from each other, indirectly forming a buckle installation operation.

[0059] Refer to the appendix Figure 7 and Figure 8 , both ends of the main magnet block 154 are an N pole and an S pole respectively;

[0060] Both of the two sliding blocks 151 are made of a magnet material, and the adsorbed ends of the two sliding blocks 151 are an N pole or an S pole respectively;

[0061] By one of the adsorbed ends of the two sliding blocks 151 being an N pole and the other being an S pole, when the main magnet block 154 is rotationally driven, when the N pole and the S pole of the main magnet block 154 correspond to the N-pole sliding block 151 and the S-pole sliding block 151 respectively, through the principle of like poles repelling each other, the two sliding blocks 151 are driven to move away from each other, forming a separation drive for the two groups of U-shaped rods 13 and forming a buckle installation operation;

[0062] On the contrary, when the N pole and the S pole of the main magnet block 154 correspond to the S-pole sliding block 151 and the N-pole sliding block 151 respectively, through the principle of opposite poles attracting each other, the two sliding blocks 151 move in the opposite direction, forming a relative drive for the two groups of U-shaped rods 13 and forming a disassembly and assembly operation.

[0063] Embodiment 2: The difference from Embodiment 1 is as follows;

[0064] Refer to the appendix Figure 10 , a return spring 156 for resetting the main magnet block 154 is installed on the L-shaped rod 153, and one end of the L-shaped rod 153 is set to be spherical;

[0065] By rotationally driving the L-shaped rod 153, the main magnet block 154 can be rotationally driven. By setting one end of the L-shaped rod 153 to be spherical, it is convenient to better control the rotation of the L-shaped rod 153; through the setting of the return spring 156, it is used to reset the rotated L-shaped rod 153, so as to facilitate the disassembly and assembly of the display screen 300 and the front frame 100;

[0066] On the inner side of the rear cover 200, there is a spiral guide piece 157 fixedly connected. The spiral guide piece 157 is semi-circular, and the spiral guide piece 157 is used to rotate the L-shaped rod 153 by 180 or 90 degrees;

[0067] By fixedly connecting the spiral guide piece 157 to the inner side of the rear cover 200, when the rear cover 200 is inserted into the back of the front frame 100, the insertion of the rear cover 200 can drive the spiral guide piece 157, so that the spherical end of the L-shaped rod 153 contacts the driving surface of the spiral guide piece 157;

[0068] When the rear cover 200 and the spiral guide piece 157 are continuously inserted and completely fit with the front frame 100, the spiral guide piece 157 can drive the L-shaped rod 153, and through the spiral surface of the spiral guide piece 157, the L-shaped rod 153 rotates self, forming the self-driving work of the driving member 15, realizing the self-adsorption installation work of the front frame 100 and the display screen 300, without the need for manual disassembly and assembly work, further improving the convenience of operation.

[0069] Embodiment 3: Different from Embodiment 1;

The card block member includes a connecting block 23 fixed to the inner side of the rear cover 200, and a conical card block 24 elastically connected to the insertion end of the connecting block 23 through a metal elastic sheet;

[0073] By inserting the connecting block 23 into the inside of the card sleeve frame 21 and inserting the two elastically connected conical card blocks 24 into the corresponding conical bayonets 22, the connecting block 23 can be locked with the card sleeve frame 21, forming the snap-in installation of the rear cover 200 and the display screen 300, with the function of self-locking installation, improving the convenience of the assembly of the display.

[0074] A secondary magnet block 25 is fixedly connected inside the card sleeve frame 21, and a metal positioning block 26 that can be adsorbed by the secondary magnet block 25 is fixedly connected to one end of the connecting block 23;

[0075] Through the setting of the auxiliary magnet block 25, it is used to adsorb the metal positioning block 26, which is convenient to cooperate with the conical clamping block 24 and the conical bayonet 22 to further improve the installation stability of the rear cover 200 and the display screen 300.
