LCM modules are widely used in many fields such as smart phones, tablet computers, industrial control equipment and medical instruments due to their advantages such as high resolution, low power consumption and long life. However, traditional LCM modules have some shortcomings in design and installation, especially in application scenarios that require frequent disassembly and assembly. The installation and disassembly process is often complicated and easy to damage the module itself or its surrounding components.

[0003] Traditional LCM modules are usually installed by fixing screws or welding. Although this method ensures the stability of the module to a certain extent, it is particularly inconvenient when frequent replacement or maintenance is required. Each disassembly and assembly requires the use of special tools, which is cumbersome and easy to scratch the surface of the module or damage the circuit board. In addition, the tightness of the fixing screws is difficult to control. Too tight may cause the module to deform, and too loose may cause the module to loosen, affecting the display effect.

[0004] In view of this, a LCM module is provided to overcome the above-mentioned defects. Utility Model Content

[0025] 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.

[0026] Embodiment 1

[0027] See also Figure 1-4 A LCM module includes a core block 1, a protective frame 3 is fixedly installed on the outer wall of the core block 1, a bottom shell 2 is arranged below the protective frame 3, a mounting block 35 is arranged at the bottom end of the protective frame 3, a telescopic rod 36 is fixedly connected to one side of the mounting block 35, an upper clamping block 38 is fixedly connected to the other end of the telescopic rod 36, a reset spring 37 is fixedly connected between the upper clamping block 38 and the mounting block 35, an accommodating cavity 21 is opened inside the bottom shell 2, a lower clamping block 22 is fixedly installed on the inner wall of the accommodating cavity 21, the lower clamping block 22 is adapted to the upper clamping block 38, a support frame 33 is integrally formed at the bottom of the protective frame 3, and the mounting block 35 is fixedly connected to the bottom of the support frame 33.

[0028] For further information, see Figure 3 A plug-in rod 4 is arranged below the support frame 33, a docking column 24 is fixedly installed at the bottom of the inner wall of the accommodating chamber 21, and an expansion groove 23 is arranged above the docking column 24. The docking column 24 is adapted to the plug-in rod 4. The number of the plug-in rod 4, the docking column 24 and the expansion groove 23 is four, and the four plug-in rods 4 and the docking column 24 are adapted at the same time. By arranging the plug-in rod 4 and the docking column 24 to be adapted, and installing the expansion groove 23 above the docking column 24, the plug-in rod 4 can be quickly plugged in through the expansion groove 23, thereby completing the positioning docking.

[0029] For further information, see Figure 1A through slot 31 is provided on the top surface of the protective frame 3, and a slidable push block 32 is provided inside the through slot 31. The push block 32 is fixedly connected to a connecting block 39, and the connecting block 39 is fixedly connected to the rear side of the upper clamping block 38. By providing the through slot 31 and the push block 32, and arranging the push block 32 to be fixedly connected to the connecting block 39, and the connecting block 39 is fixedly connected to the rear side of the upper clamping block 38, the user can move the upper clamping block 38 by sliding the push block 32, so that the clamping of the bottom shell 2 and the protective frame 3 in the device can be quickly controlled by the user.

[0030] During the specific implementation, the user needs to first install the bottom shell 2 among other components, and then directly snap the protective frame 3 and the core assembly block 1 into the bottom shell 2. During the snapping process, it is necessary to align two or four plug-in rods 4 with the four expansion grooves 23, and then plug the plug-in rods 4 into the docking column 24 and plug them into place. During the plugging process, the two upper plug-in blocks 38 below the protective frame 3 will directly contact the lower plug-in block 22, and since the relative surfaces of the upper plug-in block 38 and the lower plug-in block 22 are both inclined, the upper plug-in block 38 will retract toward the mounting block 35 due to the resistance of the lower plug-in block 22, so that the plug-in rod 4 can be plugged into the docking column 24, and after the upper plug-in block 38 passes through the lower plug-in block 22, the elastic force of the reset spring 37 will resist the upper plug-in block 38 to reset, so that the top surface of the upper plug-in block 38 directly resists the bottom surface of the lower plug-in block 22, so that the bottom shell 2 and the protective frame 3 in the device are stuck, thereby completing the splicing of the entire device.

[0031] When disassembly is required, the four push blocks 32 are pushed toward the center of the device at the same time to retract the upper clamping block 38, so that the clamping connection between the protective frame 3 and the bottom shell 2 disappears. At this time, the protective frame 3 is directly lifted upward together with the core block 1 to complete the disassembly of the protective frame 3 and the core block 1, which is convenient for the user to inspect and maintain the core block 1 or the circuit of the core block 1, so that the core block 1 can be used normally.

[0032] By setting an upper clamping block 38 and a lower clamping block 22, and connecting a telescopic rod 36 and a return spring 37 on one side of the upper clamping block 38, the user can quickly complete the installation and disassembly of the core assembly block 1 and the protective frame 3 with just two hands. At the same time, except for the bolts required for installing the bottom shell 2, the other parts are all clamping structures, so that the device will not be easily damaged by the bolts, thereby increasing the practicality of the device.

[0033] Embodiment 2

[0034] In the inheritance of Example 1, please refer to Figure 1-4 , an LCM module, a resistance spring 25 is fixedly installed on the bottom of the inner wall of the accommodating cavity 21, a spring washer 26 is fixedly connected to the top of the resistance spring 25, and the resistance spring 25 is sleeved on the outer wall of the docking column 24.

[0035] For further information, see Figure 3 A rubber pad 34 is fixedly connected to the bottom of the support frame 33, and the plug-in rod 4 is connected to the bottom end of the rubber pad 34. The existence of the rubber pad 34 ensures that the spring washer 26 will not directly damage the protective frame 3 or the core assembly 1 after the bottom shell 2 and the protective frame 3 are connected. At the same time, it can also make the connection between the protective frame 3 and the bottom shell 2 more stable.

[0036] In specific implementation, during the process of the protective frame 3 and the bottom shell 2 being clamped together, the rubber pad 34 will directly contact the spring 25 and the spring washer 26, pressing the spring washer 26 downward. After the protective frame 3 and the bottom shell 2 are completely clamped together, the resistance spring 25 installed under the spring washer 26 will continue to apply elastic force to the protective frame 3, thereby making the clamping of the upper clamping block 38 and the lower clamping block 22 more stable and will not fall off easily without human power.

[0037] By providing the resisting spring 25, the spring washer 26 and the rubber pad 34, the protective frame 3 and the bottom shell 2 in the device are always subjected to the elastic force of the resisting spring 25 after the clamping is completed, so that the clamping of the bottom shell 2 and the protective frame 3 is more secure and will not fall off easily without human power.

[0038] In addition, the core block 1 includes a liquid crystal display screen, a backlight assembly, and a driver circuit board. These components are all existing technologies and therefore will not be described in detail here.

[0039] Working principle: the user needs to install the bottom shell 2 among other components first, and then directly snap the protective frame 3 and the core assembly block 1 into the bottom shell 2. During the snap-in process, it is necessary to align two or four plug-in rods 4 with the four expansion grooves 23, and then plug the plug-in rods 4 into the docking column 24 and plug them into place. During the plug-in process, the two upper plug-in blocks 38 below the protective frame 3 will directly contact the lower plug-in block 22, and because the relative surfaces of the upper plug-in block 38 and the lower plug-in block 22 are both inclined, the upper plug-in block 38 will retract toward the mounting block 35 due to the resistance of the lower plug-in block 22, so that the plug-in rod 4 can be plugged into the docking column 24, and after the upper plug-in block 38 passes through the lower plug-in block 22, the elastic force of the reset spring 37 will resist the upper plug-in block 38 to reset, so that the top surface of the upper plug-in block 38 directly resists the bottom surface of the lower plug-in block 22, so that the bottom shell 2 and the protective frame 3 in the device are stuck, thereby completing the splicing of the entire device.

[0040] When disassembly is required, the four push blocks 32 are pushed toward the center of the device at the same time to retract the upper clamping block 38, so that the clamping connection between the protective frame 3 and the bottom shell 2 disappears. At this time, the protective frame 3 is directly lifted upward together with the core block 1 to complete the disassembly of the protective frame 3 and the core block 1, which is convenient for the user to inspect and maintain the core block 1 or the circuit of the core block 1, so that the core block 1 can be used normally.

[0041] During the process of snapping the protective frame 3 and the bottom shell 2 together, the rubber pad 34 will directly contact the spring 25 and the spring washer 26, pressing the spring washer 26 downward. After the protective frame 3 and the bottom shell 2 are snapped together, the contact spring 25 installed under the spring washer 26 will continue to apply elastic force to the protective frame 3, thereby making the snapping of the upper snapping block 38 and the lower snapping block 22 more stable and will not fall off easily without human power.

[0042] By setting an upper clamping block 38 and a lower clamping block 22, and connecting a telescopic rod 36 and a return spring 37 on one side of the upper clamping block 38, the user can quickly complete the installation and disassembly of the core assembly block 1 and the protective frame 3 with just two hands. At the same time, except for the bolts required for installing the bottom shell 2, the other parts are all clamping structures, so that the device will not be easily damaged by the bolts, thereby increasing the practicality of the device.

[0043] By providing the resisting spring 25, the spring washer 26 and the rubber pad 34, the protective frame 3 and the bottom shell 2 in the device are always subjected to the elastic force of the resisting spring 25 after the clamping is completed, so that the clamping of the bottom shell 2 and the protective frame 3 is more secure and will not fall off easily without human power.
