Description

Technical Field

[0001] This application relates to the field of external hard drive enclosure technology, specifically a waterproof external hard drive enclosure for computers. Background Technology

[0002] With the popularization of computer technology and the increasing demand for data storage, external hard drive enclosures, as a convenient and efficient data storage and transmission device, have been widely used in various fields, including personal office, creative design, scientific research and education, enterprise data storage and backup, as well as outdoor exploration and travel. This device not only provides users with flexible data storage solutions, but also greatly improves the convenience and security of data transmission.

[0003] However, in practical use, the waterproof performance of external hard drive enclosures has always been a key concern. Poor waterproofing can easily damage the internal components of the hard drive, leading to data loss or corruption. Traditional hard drive enclosures rely solely on simple sealing covers to prevent the ingress of external moisture and dust. However, this design often suffers from inadequate sealing or loosening of the cover, resulting in less than ideal waterproofing. Furthermore, while some enclosures employ more complex waterproofing structures, this often leads to increased size and weight, and more complicated operation, causing inconvenience for users.

[0004] Therefore, this application provides a waterproof external hard drive enclosure for computers to solve the above problems. Utility Model Content

[0005] This application provides a waterproof external hard drive enclosure for computers, aiming to solve the problems mentioned in the background art, such as poor sealing, easy loosening, or increased size and inconvenience of operation caused by complex waterproof structures in existing external hard drive enclosures.

[0006] To achieve the above objectives, this application provides the following technical solution: a waterproof external hard drive enclosure for computers, including a enclosure body and a USB port opened at one end of the enclosure body, wherein a sealing cover is slidably connected to the enclosure body at the position corresponding to the USB port.

[0007] The external hard drive enclosure also includes an elastic element fixedly disposed within the USB port for sealing, and a transmission structure disposed on the enclosure body and connected to the sealing cover for transmitting power from the sealing cover to the elastic element, causing the elastic element to contract and expand. The sealing cover is designed to completely cover the USB port when it is not in use, effectively preventing the entry of external moisture and dust. The elastic element acts as a second line of defense. When the sealing cover is closed, the elastic element expands and fits tightly around the USB port through the action of the transmission structure, forming a more reliable sealing effect and further improving the waterproof effect. At the same time, when the sealing cover is opened, the elastic element contracts through the action of the transmission structure to allow the USB port to be used.

[0008] Preferably, in order to facilitate sealing of the USB port through expansion and contraction, the elastic element is an airbag; the airbag has good elasticity and plasticity, and can expand and contract according to the shape and size of the USB port, so as to more flexibly adapt to the slight changes of the USB port and ensure the sealing performance for long-term use.

[0009] Preferably, to facilitate the transmission of the sliding power of the sealing cap to the elastic element, the transmission structure includes a rack fixedly disposed above the sealing cap near the USB port and slidably connected to the housing; a connecting shaft rotatably connected to the housing and located on the USB port side; a gear fixedly sleeved on the connecting shaft and meshing with the rack; and an air cylinder assembly disposed within the housing and meshing with the gear for inflating and contracting the airbag. The meshing of the rack and gear ensures that the sliding power of the sealing cap is efficiently transmitted to the gear, thereby driving the air cylinder assembly. This design not only improves transmission efficiency but also ensures the stability and reliability of the transmission structure.

[0010] Preferably, to facilitate the inflating and deflating of the airbag, the air cylinder assembly includes a cylinder fixedly disposed within the housing at a position corresponding to the lower position of the gear, a piston that moves longitudinally within the cylinder, a push rod that extends longitudinally through the top of the cylinder and is fixedly connected to the piston, a connecting plate fixedly connected to the top of the push rod and located at the bottom of the connecting shaft, a screw rod whose two ends are rotatably connected to the bottom of the connecting shaft and the top of the cylinder, respectively, and an air tube fixedly disposed at the bottom of the cylinder and communicating with the airbag inside the cylinder. The connecting plate is screwed to the screw rod, the push rod is slidably connected to the cylinder, and the connecting plate is slidably connected to the housing. This design allows the gear to smoothly drive the screw rod and push rod to move when rotating, thereby realizing the inflation and deflation of the airbag.

[0011] Preferably, in order to ensure the use of the transmission structure, the transmission structure further includes a guide block fixedly disposed below the side of the sealing cover near the USB port; the design of the guide block restricts the sliding trajectory of the sealing cover and prevents it from deviating or shaking during the sliding process, which not only improves the sliding stability of the sealing cover, but also ensures the correct meshing between the rack and the gear.

[0012] Preferably, in order to facilitate the installation and use of the guide block and the rack, the box body is provided with a sliding groove at the position corresponding to the guide block and the rack for sliding; the opening of the sliding groove provides sufficient sliding space for the guide block and the rack, ensuring the smoothness and stability of the sealing cover during the sliding process.

[0013] Preferably, to facilitate the movement of the sealing cover, an anti-slip texture is fixedly provided on the side of the sealing cover away from the USB port; the anti-slip texture increases the friction of the sealing cover surface, making it more convenient and effortless for the user to move the sealing cover.

[0014] This waterproof external hard drive enclosure for computers can be completely covered when the USB port is not in use by setting a sealing cover, effectively preventing the entry of external moisture and dust;

[0015] This waterproof external hard drive enclosure for computers uses an elastic element as a second line of defense against water damage. When the cover is closed, the elastic element expands and fits tightly around the USB port through a transmission mechanism, creating a more reliable seal and further improving the waterproof effect. When the cover is opened, the elastic element contracts through the transmission mechanism to allow the USB port to be used.

[0016] This waterproof external hard drive enclosure integrates the sealing cover, elastic element, and transmission structure onto or inside the enclosure, without increasing the overall size of the enclosure, and is easy to operate. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This embodiment provides a waterproof external hard drive enclosure for computers, such as... Figure 1-Figure 5 As shown, the computer external hard drive enclosure includes a housing 1 and a USB port 2 opened at one end of the housing 1. A sealing cover 3 is slidably connected to the housing 1 at the position corresponding to the USB port 2. The computer external hard drive enclosure also includes an elastic element 4 fixedly disposed in the USB port 2 for sealing and a transmission structure 5 disposed on the housing 1 and connected to the sealing cover 3 for transmitting power from the sealing cover 3 to the elastic element 4, causing the elastic element 4 to contract and expand.

[0030] In order to facilitate the sealing of the USB port 2 through expansion and contraction, the elastic element 4 is an airbag; the airbag has good elasticity and plasticity, and can expand and contract according to the shape and size of the USB port 2, so as to more flexibly adapt to the slight changes of the USB port 2 and ensure the sealing performance for long-term use.

[0031] When not in use, the user manually slides the sealing cover 3 to move it to the USB port 2, sealing the port. Simultaneously, as the sealing cover 3 slides closed via the transmission structure 5, the elastic element 4 expands and presses tightly against the USB port 2, further sealing the port and improving its waterproof effect. When the USB port 2 needs to be used, the user slides the sealing cover 3 in the opposite direction, moving it away from the USB port 2 and releasing the seal. At the same time, the elastic element 4 contracts again via the transmission structure 5, releasing the seal on the USB port 2, allowing the user to use it.

[0032] Specifically, the transmission structure 5 includes a rack 51 fixedly disposed above the sealing cover 3 near the USB port 2 and slidably connected to the box body 1, a connecting shaft 53 rotatably connected inside the box body 1 and located on the side of the USB port 2, a gear 54 fixedly sleeved on the connecting shaft 53 and meshing with the rack 51, and an air cylinder assembly 55 disposed inside the box body 1 and connected to the gear 54 for inflating and contracting the airbag.

[0033] When the user slides the sealing cover 3 to close, the rack 51 moves accordingly. Since the rack 51 meshes with the gear 54, and the gear 54 is connected to the connecting shaft 53, the gear 54 rotates synchronously when the rack 51 moves. After the gear 54 rotates, it transmits power to the air pump assembly 55 through the connecting shaft 53, thereby inflating the airbag and further sealing the USB port 2, improving the waterproof effect. Conversely, when the user slides the sealing cover 3 to open, the rack 51 moves accordingly as the sealing cover 3 slides in the opposite direction. At this time, the rack 51 also drives the gear 54 to rotate in the opposite direction. Similarly, the gear 54 transmits reverse power to the air pump assembly 55 through the connecting shaft 53, causing the air pump assembly 55 to draw gas from the airbag and inflate the airbag so that the user can plug in and use the USB port 2.

[0034] In addition, to ensure the use of the transmission structure 5, the transmission structure 5 also includes a guide block 52 fixedly installed on the lower side of the sealing cover 3 near the USB port 2. The housing 1 is provided with a groove 11 for the guide block 52 and the rack 51 to slide at the positions corresponding to the guide block 52 and the rack 51. The cooperative design of the guide block 52 and the groove 11 restricts the sliding trajectory of the sealing cover 3 and prevents it from deviating or shaking during the sliding process. This not only improves the sliding stability of the sealing cover 3, but also ensures the correct meshing between the rack 51 and the gear 54.

[0035] Furthermore, the air pump assembly 55 includes a cylinder 551 fixedly disposed inside the housing 1 at a position below the corresponding gear 54, a piston 552 that moves longitudinally within the cylinder 551, a push rod 553 that extends longitudinally through the top of the cylinder 551 and is fixedly connected to the piston 552, a connecting plate 555 fixedly connected to the top of the push rod 553 and located at the bottom of the connecting shaft 53, a screw 554 whose two ends are respectively rotatably connected to the bottom of the connecting shaft 53 and the top of the cylinder 551, and an air pipe 556 fixedly disposed at the bottom of the cylinder 551 and communicating with the air bladder inside the cylinder 551. The connecting plate 555 is screwed to the screw 554, the push rod 553 is slidably connected to the cylinder 551, and the connecting plate 555 is slidably connected inside the housing 1.

[0036] It should be added that a wall is provided in the box body 1 at the position corresponding to the air cylinder assembly 55 for the installation of the air cylinder assembly 55, the cylinder body 551 is fixed in the cavity, and the connecting plate 555 slides in the cavity.

[0037] When the user slides to close the sealing cover 3, and the rack 51 drives the gear 54 to rotate, the connecting shaft 53 transmits the rotational power of the gear 54 to the screw 554. Since the screw 554 is screwed to the connecting plate 555, and the connecting plate 555 slides in the cavity, when the screw 554 rotates, the connecting plate 555 drives the push rod 553 to move downward. Then, the push rod 553 drives the piston 552 to move towards the end of the air pipe 556 inside the cylinder 551, thereby compressing the gas inside the cylinder 551. Afterward, the compressed gas flows directly through the air pipe 556. The air is filled into the airbag, causing it to inflate. This inflates the airbag and further seals and waterproofs the USB port 2. When the user slides the sealing cover 3 to open it, the rack 51 drives the gear 54 to rotate in the opposite direction. Then, the connecting shaft 53 drives the screw 554 to rotate in the opposite direction. At this time, the reverse rotation of the screw 554 causes the connecting plate 555 to drive the push rod 553 to move upward in the opposite direction. As the push rod 553 moves, the piston 552 moves upward in the cylinder 551, drawing the gas in the airbag into the cylinder 551 through the air tube 556, causing the airbag to contract.

[0038] Understandably, in order to facilitate the movement of the sealing cover 3, the side of the sealing cover 3 away from the USB port 2 is fixedly provided with anti-slip texture 31; the anti-slip texture 31 increases the friction of the surface of the sealing cover 3, making it more convenient and effortless for the user to move the sealing cover 3.

[0039] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
