Description

Technical Field

[0001] This utility model belongs to the field of mobile storage devices, and in particular relates to a shockproof and drop-resistant protective shell for a PSSD solid-state USB flash drive. Background Technology

[0002] With the rapid development of information technology and the continuous improvement of data storage needs, PSSD solid-state USB flash drives have become the mainstream storage devices in mobile office, data backup and high-speed transmission scenarios due to their advantages such as small size, fast read and write speed, large capacity and plug and play.

[0003] However, most PSSD solid-state USB flash drives still have obvious shortcomings in their structural design. The casing is generally made of thin metal or plastic, and the USB interface is only protected by a simple end cap. The overall protection capability is weak. During daily carrying or use, they are very easy to be damaged by drops, squeezing or collisions, which can lead to data loss, unstable transmission, or even permanent damage to the device, seriously affecting its reliability and data security.

[0004] Therefore, there is a particular need for a shockproof and drop-resistant protective case for PSSD solid-state USB flash drives to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of PSSD solid-state USB flash drives, such as thin and light casings with weak protection, which are easily damaged by drops, squeezing, or collisions, resulting in data loss or device failure, this utility model provides a shockproof and drop-resistant protective casing for PSSD solid-state USB flash drives.

[0006] This utility model is achieved through the following technical approach: a shockproof and drop-resistant protective shell for a PSSD solid-state USB flash drive, comprising a rubber sleeve, a mounting shell, a sliding bracket, a solid-state USB flash drive body, a wedge block, a first spring, a limiting block, a sliding plate, a second spring, and a guide rod. The rubber sleeve covers the outside of the mounting shell. The upper part of the mounting shell has two symmetrically distributed sliding grooves, and a sliding bracket is slidably arranged between the two grooves. The lower part of the sliding bracket extends into the interior of the mounting shell. Two sliding plates are symmetrically slidably arranged inside the mounting shell. The solid-state USB flash drive body is slidably arranged between the two sliding plates and is located inside the mounting shell, forming sliding contact with them. The lower part of the sliding bracket is in contact with the solid-state USB flash drive body. The solid-state USB flash drive body is fixedly connected. Inside the mounting shell, multiple guide rods arranged in three rows and two columns are fixedly connected. The guide rods pass through the corresponding sliding plates and slide with them. Each guide rod is fitted with a spring II. The two ends of the spring II are connected to the corresponding sliding plate and the mounting shell, respectively. A wedge block is fixedly connected to both sides of the solid-state USB flash drive body. The wedge block is located above the corresponding sliding plate and forms a sliding contact with it. Two spring I arranged side by side are fixedly connected between one end of the solid-state USB flash drive body and the mounting shell. Inside the mounting shell, a limiting block is fixedly connected to both sides. The wedge block is located in front of the corresponding limiting block, and one end of its vertical plane is in contact with the front end face of the limiting block to form an initial limit.

[0007] More preferably, it also includes a crank and a limiting post, with a limiting groove provided at the front of the sliding frame, the crank rotating on the upper part of the mounting housing, the limiting post fixed to the top of one end of the crank, and the rotation trajectory of one end of the crank intersecting the limiting groove.

[0008] More preferably, it also includes a cover plate and locking pins. The cover plate is rotatably mounted at the bottom of the rubber sleeve, and two symmetrically distributed locking pins are fixedly connected to its lower part. The rear part of the mounting shell has two locking slots that match the locking pins, and the locking pins are inserted into the corresponding locking slots.

[0009] More preferably, it also includes rubber blocks, with one rubber block fixed to each end of each groove.

[0010] More preferably, the sliding stroke length of the sliding frame in the groove is equal to the total length of the wedge block and the limiting block.

[0011] More preferably, the height of the limiting post is equal to the depth of the limiting groove.

[0012] Beneficial effects: 1. By setting up a rubber sleeve and mounting shell, a multi-layer protection system is built for the solid-state USB flash drive. The mounting shell, as a rigid support structure, effectively resists external impacts such as drops and squeezing, achieving drop protection. The outer rubber sleeve uses its elastic properties to absorb vibration and impact energy, playing a shock-absorbing and buffering role, significantly improving the structural stability and data security of the solid-state USB flash drive.

[0013] 2. Through the cooperation of the limiting groove, crank and limiting post, the user can rotate the crank 180 degrees clockwise or counterclockwise to make the limiting post slide into the middle of the limiting groove, thereby locking the sliding frame and effectively preventing it from sliding accidentally during carrying or in a vibrating environment.

[0014] 3. By setting up a cover plate, locking posts, and locking slots, the opening at the back of the mounting shell can be sealed after the solid-state USB flash drive is stored, protecting the solid-state USB flash drive from external dust. Attached Figure Description

[0024] Example: A shockproof and drop-resistant protective case for PSSD solid-state USB flash drives, such as... Figures 1-8As shown, it includes a rubber sleeve 1, a mounting shell 2, a rubber block 202, a sliding frame 3, a solid-state USB flash drive body 4, a wedge block 5, a first spring 6, a limiting block 7, a sliding plate 8, a second spring 9, and a guide rod 10. The mounting shell 2 is made of high-strength, impact-resistant material, such as aluminum alloy. The rubber sleeve 1 covers the outside of the mounting shell 2 and is made of highly elastic, impact-resistant silicone or TPU material, providing external cushioning protection and effectively absorbing the impact energy during drops and collisions. The upper part of the mounting shell 2 has two symmetrically distributed sliding grooves 201, between which... A sliding frame 3 is provided, with its lower part extending into the mounting shell 2. Each sliding groove 201 has a rubber block 202 fixedly connected to both ends to cushion the impact when the sliding frame 3 slides into place, preventing it from hard-colliding with the mounting shell 2. Two sliding plates 8 are symmetrically slidably arranged inside the mounting shell 2. The solid-state USB flash drive body 4 is slidably arranged between the two sliding plates 8 and is located inside the mounting shell 2, forming a sliding contact with them. The lower part of the sliding frame 3 is fixedly connected to the solid-state USB flash drive body 4. The mounting shell 2 is fixedly connected with a series of sliding plates arranged in three rows and two columns. The device has six guide rods 10, which slide through and engage with corresponding sliding plates 8. Each guide rod 10 is fitted with a spring 9, whose upper and lower ends are connected to the corresponding sliding plate 8 and the mounting shell 2, respectively, providing a reset force for the sliding plate 8. A wedge-shaped block 5 is fixedly connected to each of the left and right sides of the solid-state USB flash drive body 4, and the wedge-shaped block 5 is positioned above the corresponding sliding plate 8 to form a sliding contact with it. Two springs 6 are fixedly connected side-by-side between the rear end of the solid-state USB flash drive body 4 and the mounting shell 2, and the springs 6 provide a reset force for the solid-state USB flash drive body 4. With force, a limiting block 7 is fixedly connected to both the left and right sides inside the housing 2. The wedge block 5 is located in front of the corresponding limiting block 7, and its rear vertical plane is in contact with the front face of the limiting block 7 to form an initial limit, preventing the solid-state USB flash drive body 4 from accidentally sliding out. The sliding plate 8 is located below the corresponding limiting block 7 and in contact with it. The sliding stroke length of the sliding frame 3 in the slide groove 201 is equal to the total length of the wedge block 5 and the limiting block 7. When the sliding frame 3 slides backward to the last end of the slide groove 201, the front vertical plane of the wedge block 5 is exactly aligned with the rear face of the limiting block 7.

[0025] like Figure 1 and Figure 4 As shown, it also includes a crank 11 and a limiting post 12. A limiting groove 301 is provided at the front of the sliding frame 3. The crank 11 is rotatably mounted on the upper part of the mounting shell 2. The limiting post 12 is fixedly connected to the top of the front end of the crank 11. The rotation trajectory of the front end of the crank 11 intersects with the limiting groove 301. When the crank 11 rotates, the limiting post 12 can slide into the limiting groove 301 along the rotation trajectory. The height of the limiting post 12 is equal to the depth of the limiting groove 301, ensuring that the limiting post 12 can be completely embedded in the limiting groove 301 after the crank 11 rotates.

[0026] like Figure 1 , Figure 6and Figure 7 As shown, it also includes a cover plate 13 and locking posts 14. The cover plate 13 is rotatably mounted at the bottom of the rubber sleeve 1, and two symmetrically distributed locking posts 14 are fixedly connected to its lower part. The rear part of the mounting shell 2 has two slots 15 that match the locking posts 14. The locking posts 14 are inserted into the corresponding slots 15 to fix the cover plate 13 to the rear part of the mounting shell 2, thereby closing the rear opening of the mounting shell 2. The locking posts 14 are made of a material with elastic deformation capability, such as polycarbonate, which can generate moderate elastic stress when inserted into the slots 15 to achieve a tight fit and ensure that the cover plate 13 and the mounting shell 2 are tightly connected.

[0027] In the initial state, spring 6 is compressed, and the rear vertical plane of wedge block 5 is in contact with the front face of limit block 7, thereby limiting the solid USB flash drive body 4 to a predetermined position inside the mounting shell 2 to prevent it from accidentally sliding out.

[0028] When the solid-state USB flash drive body 4 is needed, the user first rotates the cover plate 13 upwards to allow the locking pin 14 to disengage smoothly from the locking slot 15, thereby opening the rear opening of the mounting shell 2. Then, the user presses down on the sliding bracket 3 with a small amount of force. The sliding bracket 3 slides smoothly downwards along the sliding groove 201, simultaneously moving the solid-state USB flash drive body 4 downwards. Since the solid-state USB flash drive body 4 is fixedly connected to the sliding plate 8, the sliding plate 8 will also move downwards along with it. During the downward movement, the sliding plate 8 slides along the guide rod 10 and compresses the spring 9 sleeved on the outside of the guide rod 10. At the same time, the wedge block 5 moves downwards with the solid-state USB flash drive body 4, and its rear vertical plane gradually shifts away from the front face of the limiting block 7, changing to an angled face aligned with the front face of the limiting block 7. At this time, the wedge block 5 is no longer blocked vertically by the limiting block 7, and the elastic force accumulated by the spring 6 due to previous compression is released. The user's hand can clearly feel the elastic force through the sliding bracket 3. The spring 6 releases the reverse force generated by the elastic force, and then slides the sliding bracket 3 backward a certain distance along the direction of the elastic force of the spring 6 before releasing it. During this process, the inclined surface of the rear end of the wedge block 5 smoothly passes the limiting block 7. When the top surface of the wedge block 5 is aligned with the bottom surface of the limiting block 7, the spring 6 fully releases the compression force, pushing the solid-state USB flash drive body 4 to slide backward quickly, so that its USB interface extends out from inside the mounting shell 2, facilitating data transfer operations for the user. When the sliding bracket 3 slides backward to the last end of the slide groove 201, the solid-state USB flash drive body 4 slides backward into place, and the vertical plane of the front end of the wedge block 5 is vertically aligned with the rear end face of the limiting block 7. At this time, the spring 9 returns to its original state, pushing the sliding plate 8 to drive the solid-state USB flash drive body 4 to slide upward to the initial height. At this time, the vertical plane of the front end of the wedge block 5 is in contact with the rear end face of the limiting block 7, forming a stable limit, ensuring that the solid-state USB flash drive body 4 remains stable during use.

[0029] When the solid-state USB flash drive 4 is not in use, press down on the sliding bracket 3 with considerable force to move the sliding plate 8 down and compress the second spring 9. The wedge block 5 completely offsets the limiting block 7. Then slide the sliding bracket 3 forward, causing the solid-state USB flash drive 4 to slide forward. The USB interface of the solid-state USB flash drive 4 gradually retracts into the mounting shell 2. During this process, the solid-state USB flash drive 4 compresses the first spring 6, fully preparing for the next ejection. When the sliding bracket 3 slides forward to the front end of the slide groove 201, release the sliding bracket 3. The second spring 9 returns to its elasticity, pushing the sliding plate 8 to move the solid-state USB flash drive... The disk body 4 slides upward to the initial height. At this time, the vertical plane of the rear end of the wedge block 5 re-contacts the front end of the limiting block 7, and firmly limits the solid-state USB disk body 4 inside the mounting shell 2 again. Then, the cover plate 13 is rotated downward to insert the locking post 14 back into the locking groove 15, sealing the rear opening of the mounting shell 2 and protecting the solid-state USB disk body 4 from external dust. Finally, the crank 11 is rotated clockwise or counterclockwise to 180 degrees, so that the limiting post 12 slides into the middle of the limiting groove 301, thereby locking the sliding frame 3 and preventing the sliding frame 3 from accidentally sliding during carrying or vibration.
