DETAILED DESCRIPTION

[0032] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be understood that in the description of the present invention, the specific embodiments are only used to explain the present invention, rather than to limit the present invention. Among them, the exemplary embodiments are described as processes or methods depicted as flowcharts; although the flowchart describes the processing of various operations or steps in a certain order, many of the operations or steps can be implemented in parallel, concurrently or simultaneously, and the order of the operations can be rearranged. When its operation or step is completed, the corresponding processing can be terminated, and there can also be additional steps not included in the drawings. The aforementioned processing can correspond to methods, functions, procedures, subroutines, subprograms, etc., and the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0034] The term "including" and its variations used in the present invention are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The technical solution of the present invention is further described below in conjunction with the accompanying drawings and through specific implementation methods; it can be understood that for the sake of ease of description, the accompanying drawings only show parts related to the present invention rather than all structures.

[0035] Please refer to Figures 1 to 3 The present invention provides a screen module, which is applied to a notebook computer in this embodiment. It can be understood that the screen module can also be applied to other electronic devices with screens.

[0036] In this embodiment, the screen module includes a main screen 11, which is a touch screen. It can be understood that a screen module in which the main screen 11 is a touch screen often needs to be provided with a PCB board 13 to realize the screen display and touch functions of the main screen 11. Therefore, in this application, the screen module also includes a PCB board 13 connected to the main screen 11.

[0037] Furthermore, a function switch 131 is provided on the PCB board 13. It is understandable that the function switch 131 may be a power switch, a touch function switch 131 of a touch screen, or a fingerprint recognition switch, etc., all of which are within the protection scope of this embodiment.

[0038] In this embodiment, the screen module also includes a function module, which includes a key assembly 21, and the key assembly 21 is aligned with the function switch 131 on the PCB board 13, so when the key assembly 21 is pressed, the key assembly 21 can press the function switch 131. In this embodiment, the function switch 131 is a power switch, so when the key assembly 21 is used to press the function switch 131, the laptop can be turned on or off.

[0039] In this embodiment, some function modules corresponding to specific functions in the notebook computer are arranged on the screen module, and a function switch 131 for cooperating with the key assembly 21 of the function module to realize turning on and off the specific function is arranged on the PCB board 13 of the screen module;

[0040] Since the PCB board 13 of the screen module originally needs to be connected to the main board in the host module, the functional module does not need to be connected to the main board in the host module again, which saves the process of connecting the functional module to the main board in the host module, effectively improves the assembly efficiency of the laptop computer, and reduces the production cost of the laptop computer.

[0041] In order to achieve the coordination between the key assembly 21 and the PCB board 13, in the present embodiment, a key protrusion 2111 is provided on the side of the key assembly 21 close to the PCB board 13, and the function switch 131 includes a raised contact. When the key assembly 21 is in a natural state, there is a gap between the key assembly 21 and the function switch 131. When the key assembly 21 is pressed, the key protrusion 2111 contacts the contact.

[0042] Specifically, the screen module also includes a bottom shell 121 and a top shell. The main screen 11 is arranged on the bottom shell 121. The top shell is connected to one side of the main screen 11 and is arranged opposite to the bottom shell 121. A accommodating space is formed between the top shell and the bottom shell 121. The PCB board 13 is arranged on the bottom shell 121 in the accommodating space, and the button assembly 21 is arranged on the top shell.

[0043] Among them, a plastic part 1211 is provided on the bottom shell 121, and the shape structure of the plastic part 1211 matches the shape structure of each component required to be installed in the screen module, so as to achieve stable installation of each component.

[0044] In this embodiment, the top shell is located at the bottom of the main screen 11, and preferably, the upper surface of the top shell is roughly flush with the upper surface of the main screen 11 to ensure the flatness of the surface of the screen module, which is beneficial to reducing the thickness of the laptop computer when the screen module and the host module are covered.

[0045] Among them, a mounting hole is opened on the top shell, and the key assembly 21 includes a key base 211 and a key body 212 fixed on the key base 211. The key base 211 can be driven to make axial movement along the mounting hole, that is, the key base 211 can move in a direction close to the PCB board 13 under external force until it hits the contact in the function switch 131.

[0046] Please Figures 1 to 3 Based on this, we also refer to Figure 4 , Figure 5A mounting plate 22 is fixedly arranged on the inner side of the top shell, a slot 222 is opened on the mounting plate 22, and a hook 2112 is provided on the button base 211; when the button assembly 21 is in a natural state, the hook 2112 is engaged with the slot 222; when the button assembly 21 is pressed, the hook 2112 is disengaged from the slot 222, so that the button protrusion 2111 can cooperate with the function switch 131.

[0047] In this embodiment, the mounting plate 22 covers the mounting hole, and the slot 222 is located at the edge of the mounting plate 22, which is conducive to improving the installation stability of the key assembly 21. Correspondingly, the hook 2112 is located at the edge of the key base 211, and the position of the hook 2112 corresponds to the position of the slot 222.

[0048] In order to prevent the mounting plate 22 from interfering with the coordinated action between the button assembly 21 and the function switch 131, an avoidance hole 221 is opened on the mounting plate 22, and the avoidance hole 221 is aligned with the button protrusion 2111; when the button assembly 21 is pressed, the button protrusion 2111 extends from the avoidance hole 221 to achieve coordinated action with the function switch 131.

[0049] The mounting plate 22 is provided with a plurality of fixing holes, in which heat-melting posts 223 are provided, and the mounting plate 22 is fixedly connected to the top shell via the heat-melting posts 223. It is understandable that the mounting plate 22 and the top plate can also be fixed by screwing.

[0050] Based on the above embodiments, an embodiment of the present invention further provides a laptop computer, including a host module and the screen module provided in the above embodiments.

[0051] Among them, the host module includes a mainboard circuit;

[0052] The main screen 11 is a touch screen, and the PCB board 13 is provided with a display touch circuit for realizing the display and touch functions of the main screen 11, and also includes a switch circuit for realizing the opening and closing of a specific function of the notebook computer, and the switch circuit includes a function switch 131. When the key assembly 21 is pressed, the key assembly 21 can press the function switch 131.

[0053] In this embodiment, the display touch circuit and the switch circuit are connected to the mainboard circuit via the connector 132 and the cable 1321 .

[0054] By setting function modules corresponding to some specific functions in the notebook computer on the screen module, and setting a function switch 131 on the PCB board 13 of the screen module for cooperating with the key assembly 21 of the function module to realize turning on and off the specific function;

[0055] Since the PCB board 13 of the screen module originally needs to be connected to the main board in the host module, the functional module does not need to be connected to the main board in the host module again, which saves the process of connecting the functional module to the main board in the host module, effectively improves the assembly efficiency of the laptop computer, and reduces the production cost of the laptop computer.

[0056] It is understandable that the function switch 131 may be a power switch, or a touch function switch 131 of a touch screen, or a fingerprint recognition switch, etc., all of which are within the protection scope of this embodiment.

[0057] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
