Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 The present invention provides the following technical solution: A modular and expandable laptop casing assembly includes a laptop body 1, a screen casing 2, and a function expansion mechanism 3. The screen casing 2 is fixedly installed on the rear side of the screen of the laptop body 1, and the function expansion mechanism 3 is snapped onto the surface of the screen casing 2. The functional expansion mechanism 3 includes a connecting block 31, a connecting piece 32 is embedded in the rear side of the screen housing 2, the connecting piece 32 is inserted into the connecting block 31, and a snap-fit ​​component 33 is slidably arranged on both sides inside the connecting block 31, and the other end of the snap-fit ​​component 33 is in close contact with the side of the screen housing 2. An interface expansion module 34 is arranged on the rear side of the connecting block 31.

[0019] In this embodiment, the interface expansion module 34 can be integrated and installed on the screen housing 2 through the cooperation of the snap-fit ​​component 33 and the connecting piece 32. It has the advantages of quick disassembly and stable fixation, taking into account both ease of use and connection reliability. At the same time, it is easy to replace or upgrade the interface expansion module 34 separately, extending the service life of the overall components. Moreover, there is no need to modify the main body of the laptop 1. Functional upgrades can be achieved only through the expansion design of the screen housing 2, avoiding the risk of damage to the main structure or warranty failure caused by modification, and ensuring the original performance and security of the laptop. The interface expansion module 34 can solve the problems of traditional laptop function expansion relying on external devices, inconvenience of carrying, and poor compatibility. Without the need for an additional expansion dock, the interface expansion module 34 can be directly integrated through the function expansion mechanism 3 to achieve native connection of external devices.

[0020] Specifically, such as Figure 4 As shown, the snap-fit ​​assembly 33 includes a snap-fit ​​plate 331, which is slidably disposed inside the connecting block 31, and the inner side of the other end of the snap-fit ​​plate 331 is in close contact with the screen housing 2.

[0021] Specifically, such as Figure 4 As shown, two sliding rods 332 are bolted to the side of the snap-fit ​​plate 331 near the connecting block 31, and a connecting plate 333 is bolted between the two sliding rods 332 away from the snap-fit ​​plate 331. Limiting plates 334 are bolted to both sides inside the connecting block 31, and the sliding rods 332 are slidably disposed inside the limiting plates 334.

[0022] Specifically, such as Figure 4 As shown, a fastening spring 335 is sleeved on the surface of the sliding rod 332, and the fastening spring 335 is bolted to the connecting plate 333 and the limiting plate 334 on the side close to them respectively.

[0023] In this embodiment: by setting the snap-fit ​​assembly 33, when installing the connecting block 31, the two snap-fit ​​plates 331 are pulled to move away from the connecting block 31, and the sliding rod 332 and the connecting plate 333 are moved simultaneously. The limiting plate 334 can restrict the movement trajectory of the sliding rod 332 to make it move stably. At the same time, the movement of the connecting plate 333 will compress the fastening spring 335. When the two snap-fit ​​plates 331 move to the side of the screen housing 2 and contact the screen housing 2, the snap-fit ​​plates 331 are released. The elasticity of the fastening spring 335 makes the snap-fit ​​plates 331 make tight contact with the side of the screen housing 2. The sliding design of the snap-fit ​​plates 331 makes installation and disassembly only require manual operation, without the need for screwdrivers or other tools, reducing the user's operating threshold. Even non-professional users can quickly complete the disassembly and assembly, improving the user experience.

[0024] Specifically, such as Figure 6 , Figure 7As shown, interface slots are provided on the left side of the screen housing 2 and the rear side of the connecting block 31, and conductive contacts are provided inside the interface slots. Corresponding conductive contacts are provided on the front side of the interface expansion module 34 and the inner side of the left side card plate 331.

[0025] Specifically, such as Figure 6 As shown, the conductive contacts inside the connecting block 31 are electrically connected to the conductive contacts inside the snap-fit ​​plate 331 via cables.

[0026] In this embodiment: when an external device is connected to the interface expansion module 34, the device signal is transmitted through the interface expansion module 34 to its front conductive contact, and then through the conductive contact inside the connecting block 31 and the conductive contact of the interface slot of the screen shell 2, and finally transmitted to the laptop body 1. At the same time, the power of the laptop body 1 is transmitted in reverse through the same path to the interface expansion module 34 to provide power to the external device, realizing the integrated transmission of signal and power.

[0027] Specifically, such as Figure 6 As shown, the interface expansion module 34 has connecting protrusions 4 on both sides of its front side. The front side of the connecting protrusions 4 extends into the interior of the connecting block 31. Positioning beads 5 are provided on both sides of the interior of the connecting block 31. The surface of the positioning beads 5 is in close contact with the inner wall of the connecting protrusions 4. A positioning spring 6 is provided between the positioning beads 5 and the inner wall of the connecting block 31.

[0028] Specifically, such as Figure 2 , Figure 6 As shown, the interface expansion module 34 has multiple interfaces on its rear side.

[0029] In this embodiment: When installing the interface expansion module 34, align the connecting protrusion 4 on its front side with the mounting groove inside the connecting block 31, push the interface expansion module 34, the connecting protrusion 4 squeezes the positioning bead 5, the positioning bead 5 compresses the positioning spring 6 and retracts towards the inner wall of the connecting block 31. When the connecting protrusion 4 is fully inserted into the mounting groove, the positioning bead 5 is reset under the action of the positioning spring 6 and embedded in the preset groove on the inner wall of the connecting protrusion 4. The interface expansion module 34 and the connecting block 31 are fixed through mechanical engagement. The interface expansion module 34 can be disassembled and assembled without tools through the cooperation of the positioning bead 5 and the positioning spring 6. Users can replace the interface expansion module 34 with different interface types as needed without replacing the entire functional expansion mechanism 3, reducing upgrade costs and adapting to the needs of technological iteration. Furthermore, the interface expansion module 34 is provided with multiple interfaces. The integrated design of multiple interfaces covers the mainstream external device types in office and entertainment scenarios, solving the problem of insufficient number of interfaces in traditional laptops. Users do not need to frequently plug and unplug devices, improving work and entertainment efficiency.

[0030] Working principle: When multiple devices need to be connected to the laptop body 1, the connecting block 31 can be installed on the screen housing 2. Pulling the two latching plates 331 away from the connecting block 31 will simultaneously move the sliding rod 332 and the connecting plate 333. The limiting plate 334 can restrict the movement trajectory of the sliding rod 332, making it move stably. At the same time, the movement of the connecting plate 333 will compress the fastening spring 335. When the two latching plates 331 move to the side of the screen housing 2 and contact the screen housing 2, the latching will be released. Plate 331, using the elasticity of the fastening spring 335, ensures tight contact between the latching plate 331 and the side of the screen housing 2, while simultaneously connecting the conductive contacts inside the left latching plate 331 with the conductive contacts in the interface groove on the screen housing 2. Then, the connecting protrusion 4 is aligned with the mounting groove on the rear side of the connecting block 31, ensuring that the conductive contacts on the front side of the interface expansion module 34 correspond to the conductive contacts in the interface groove of the connecting block 31. The interface expansion module 34 is slowly pushed, causing the connecting protrusion 4 to enter the mounting groove and press against the positioning bead 5. The compression positioning spring 6 retracts towards the inner wall of the connecting block 31, providing space for the connecting protrusion 4 to penetrate deeper. When the connecting protrusion 4 is fully inserted into the mounting slot, the positioning bead 5 is reset under the elastic force of the positioning spring 6 and embedded in the preset slot on the inner wall of the connecting protrusion 4. The interface expansion module 34 and the connecting block 31 are firmly fixed through mechanical engagement. At this time, the conductive contacts on the front side of the interface expansion module 34 are in complete contact with the conductive contacts in the interface slot of the connecting block 31. At the same time, the conductive contacts inside the connecting block 31 form a path with the conductive contacts inside the left snap-fit ​​plate 331 through the cable, completing the electrical connection. Finally, according to the requirements, the connection cable of the external device (such as a projector or a portable hard drive) is inserted into the corresponding interface on the back side of the interface expansion module 34. The device signal is transmitted through the interface expansion module 34 to its front conductive contacts, through the conductive contacts inside the connecting block 31 and the conductive contacts in the interface slot of the screen shell 2, and finally transmitted to the main body of the laptop 1, realizing the signal communication between the device and the laptop (such as the projector displaying the laptop screen and the portable hard drive interacting with the laptop data).

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
