[0003] To address the aforementioned issues, existing patents have provided solutions. However, in existing laptop casing components, the expansion interfaces are usually directly exposed on the outside of the casing. Dust and impurities in the air can easily enter and accumulate inside the interfaces, leading to oxidation of the interface metal contacts and poor contact, which affects the normal operating efficiency of the device. Moreover, the structure of existing laptop casing components is mostly a fixed-size slot. When installing a laptop, external force is directly applied to the laptop and the components, which can cause the laptop casing or components to deform or be scratched due to uneven force, affecting the overall service life of the laptop casing components.

[0004] To address this, a laptop casing component with an expansion interface is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a laptop casing assembly with an expansion interface, which can solve the problems of existing laptop casing assemblies where the expansion interface is usually directly exposed on the outside of the casing. Dust and impurities in the air can easily enter and accumulate inside the interface, leading to oxidation of the interface metal contacts, poor contact, and affecting the normal use efficiency of the device. Moreover, the structure of existing laptop casing assemblies is mostly a fixed-size slot. When installing a laptop, external force is directly applied to the laptop and the assembly, which can cause the laptop casing or assembly to deform or be scratched due to uneven force, affecting the overall service life of the laptop casing assembly.

[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 1-5 The present invention provides the following technical solution: A laptop casing assembly with an expansion interface includes a protective shell 1, a laptop body 2 disposed inside the protective shell 1, an expansion interface assembly 3 disposed on the outer side of the protective shell 1, and a connecting assembly 4 disposed inside the protective shell 1. The expansion interface assembly 3 includes a drive motor 301 fixedly connected inside the protective shell 1. A drive gear 302 is mounted on the output end of the drive motor 301 via a transmission shaft. A rack plate 303 is meshed with the outer side of the drive gear 302. A sealing plate 304 is fixedly connected to the side of the rack plate 303 away from the drive gear 302. A sealing cover 305 is fixedly connected to the outer side of the protective shell 1. The inner wall of the sealing cover 305 is slidably connected to the surface of the sealing plate 304. An expansion interface seat 306 is disposed on the outer side of the laptop body 2 and is located inside the sealing plate 304.

[0019] In this embodiment: By activating the drive motor 301 inside the protective housing 1, which is matched with the expansion interface assembly 3, the drive motor 301 drives the drive gear 302 to rotate via the transmission shaft. Since the drive gear 302 meshes with the rack plate 303, the rotation of the drive gear 302 will cause the rack plate 303 to move horizontally. The side of the rack plate 303 away from the drive gear 302 is fixedly connected to the sealing plate 304. Therefore, the rack plate 303 will synchronously drive the sealing plate 304 to slide along the inner wall of the sealing cover 305. As the sealing plate 304 slides, the expansion interface seat 306, which was originally covered by the sealing plate 304, is gradually exposed. At this time, the operator... The external device's connection cable can be inserted into the expansion interface socket 306 to connect the external device to the laptop body 2. When the expansion interface is not needed, the drive motor 301 is controlled to rotate in reverse. The drive motor 301 drives the drive gear 302 to rotate in reverse through the transmission shaft, which in turn drives the rack plate 303 and the sealing plate 304 to slide in reverse until the sealing plate 304 completely covers the expansion interface socket 306 again. Through the cooperation of the sealing plate 304 and the sealing cover 305, external dust and impurities are prevented from entering the expansion interface socket 306, avoiding poor contact or short circuit problems caused by dust accumulation in the expansion interface socket 306, and extending the service life of the expansion interface socket 306.

[0020] Specifically, such as Figure 4 As shown, the connecting component 4 includes a fixing plate 401 fixedly connected inside the protective housing 1, and a limit support rod 402 is slidably connected to the inner side of the fixing plate 401.

[0021] Specifically, such as Figure 4 As shown, a compression spring 403 is sleeved on the outer side of the limiting support rod 402, and a connecting bracket 404 is fixedly connected to the outer side of the limiting support rod 402.

[0022] Specifically, such as Figure 4As shown, a connecting plate 405 is fixedly connected to the bottom of the notebook body 2. A pressing block 406 is fixedly connected to both sides of the connecting plate 405. The side of the pressing block 406 away from the connecting plate 405 is engaged with the connecting card slot 404.

[0023] In this embodiment: during the process of lowering the laptop body 2 along the guide rod 5 to a preset position inside the protective shell 1, the pressing blocks 406 on both sides of the bottom connecting plate 405 of the laptop body 2 will gradually come into contact with the connecting card 404 in the connecting assembly 4. As the laptop body 2 continues to be lowered, the pressing blocks 406 will apply a horizontal pressing force to the connecting card 404. After being subjected to the pressing force, the connecting card 404 will drive the limiting support rod 402 fixed thereto to slide along the inner side of the fixing plate 401. At the same time, the limiting support rod 402 The compression spring 403 on the outside will be squeezed and undergo elastic deformation due to the sliding of the limiting support rod 402. When the laptop body 2 is lowered to the final position, the pressing block 406 will be fully embedded in the slot of the connecting card holder 404. At this time, the tendency of the compression spring 403 to restore elastic deformation will generate a reverse thrust on the limiting support rod 402, pushing the connecting card holder 404 and the pressing block 406 to fit tightly, thereby fixing the laptop body 2 stably inside the protective shell 1 and preventing the laptop body 2 from shaking during use or carrying.

[0024] Specifically, such as Figure 2 , Figure 5 As shown, a guide rod 5 is fixedly connected inside the protective shell 1, and a guide sleeve 6 is fixedly connected to the bottom of the notebook body 2. The guide sleeve 6 is slidably connected to the guide rod 5.

[0025] Specifically, such as Figure 5 As shown, a servo motor 7 is fixedly connected inside the protective housing 1. An adjusting screw 8 is fixedly connected to the output end of the servo motor 7. A movable support plate 9 is threadedly connected to the outer side of the adjusting screw 8. The movable support plate 9 is slidably connected to the protective housing 1. The side of the movable support plate 9 away from the adjusting screw 8 is fixedly connected to the front fixed plate 401.

[0026] In this embodiment: by setting guide rod 5 and guide sleeve 6, when the protective top cover 10 is opened and the laptop body 2 is prepared to be placed into the protective shell 1, the guide sleeve 6 at the bottom of the laptop body 2 will first align with the guide rod 5 preset inside the protective shell 1. As the laptop body 2 is gradually lowered, the guide sleeve 6 will slide smoothly along the outer wall of the guide rod 5. During this process, the guide rod 5 restricts and guides the lowering trajectory of the laptop body 2 through the sliding cooperation with the guide sleeve 6, avoiding positional deviation or tilting of the laptop body 2 during placement, ensuring that the laptop body 2 can accurately land in the preset position inside the protective shell 1. By setting servo motor 7, When the fixing of the notebook body 2 is released, the servo motor 7 inside the protective shell 1 is activated. After the servo motor 7 runs, it will drive the adjusting screw 8 fixed at its output end to rotate synchronously. Since the adjusting screw 8 and the moving support plate 9 are connected by threads, and the moving support plate 9 and the protective shell 1 are in sliding fit, the rotation of the adjusting screw 8 will be converted into the linear sliding of the moving support plate 9 along the inner wall of the protective shell 1. Since the side of the moving support plate 9 away from the adjusting screw 8 is fixedly connected to the front fixed plate 401, when the moving support plate 9 slides, it will drive the fixed plate 401 to move together, thereby releasing the fixing of the connecting plate 405 and the pressing block 406.

[0027] Specifically, such as Figure 2 As shown, a protective top cover 10 is hinged to the top of the protective housing 1, and a grip plate 11 is fixedly connected to the outer side of the protective top cover 10.

[0028] Specifically, such as Figure 2 As shown, a rubber support 12 is fixedly connected inside the protective shell 1, and the rubber support 12 is located at the bottom of the laptop body 2.

[0029] In this embodiment: By setting a protective top cover 10 and a pull plate 11, when it is necessary to put the laptop body 2 into the protective housing 1 or take it out of the protective housing 1, the operator holds the pull plate 11 on the outside of the protective top cover 10 and applies a pulling force away from the protective housing 1. Since the protective top cover 10 is hinged to the top of the protective housing 1, the protective top cover 10 will rotate around the hinge point and gradually open, thereby exposing the internal accommodating space of the protective housing 1, which makes it convenient for the operator to pick up and put down the laptop body 2. By setting a rubber support 12, when the laptop body 2 is lowered into the protective housing 1 along the guide rod 5, when the bottom of the laptop body 2 contacts the rubber support 12 inside the protective housing 1, the rubber support 12 will rely on its own elasticity to buffer the impact force generated when the laptop body 2 is lowered, avoiding a rigid collision between the bottom of the laptop body 2 and the hard structure inside the protective housing 1, reducing the risk of scratches or damage to the bottom of the laptop body 2 due to the collision.

[0030] Working principle: When using this laptop casing assembly with an expansion interface, first open the protective top cover 10 using the pull plate 11 on the protective top cover 10, then place the laptop body 2 inside the protective casing 1. The bottom of the laptop body 2 is supported by the rubber support 12 inside the protective casing 1. At the same time, the guide sleeve 6 at the bottom of the laptop body 2 slides along the guide rod 5 inside the protective casing 1 to achieve guidance and positioning during placement. During the placement of the laptop body 2, the pressing blocks 406 on both sides of the bottom connecting plate 405 will contact and press against the connecting card 404. The connecting card 404 then transmits the force to the limiting support rod 402, causing the limiting support rod 402 to slide along the inner side of the fixing plate 401. At the same time, the compression spring 403 on the outer side of the limiting support rod 402 is compressed and contracts until the pressing block 406 and the connecting card 404 are fully engaged, thereby completing the fixation of the laptop body 2 inside the protective casing 1. If it is necessary to release the connection assembly 4, When the protective housing 1 is in use, the servo motor 7 inside the protective housing 1 drives the adjusting screw 8 to rotate. When the adjusting screw 8 rotates, it drives the outer movable support plate 9 to slide along the protective housing 1. The movable support plate 9 then drives the fixed plate 401 to move synchronously, thereby releasing the laptop. When the expansion interface is needed, the drive motor 301 inside the protective housing 1 drives the drive gear 302 to rotate. The drive gear 302 meshes with the rack plate 303, causing the rack plate 303 to drive the sealing plate 304 to slide along the inner wall of the sealing cover 305, exposing the expansion interface seat 306 inside the sealing cover 305 so that external devices can connect to the expansion interface seat 306. When the expansion interface is not needed, the drive motor 301 will rotate in the opposite direction. Through the meshing of the drive gear 302 and the rack plate 303, the sealing plate 304 will be reset, causing the sealing plate 304 to slide again on the inner wall of the sealing cover 305 and cover the expansion interface seat 306, thereby achieving dust protection for the expansion interface seat 306.

[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.
