Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of computer hardware, in particular to an external computer memory. Background Art
[0002] As the main storage device of the computer, the hard disk is usually composed of components such as a magnetic head, a disk, an engine, and a main control chip. According to the different ways of reading, writing, and storing data, hard disks are divided into two categories: solid-state hard disks and mechanical hard disks. Among them, mechanical hard disks are used as extended hard disks due to their low reading and writing speeds, but large storage capacity and stable operation. The disk of the existing mechanical hard disk is a circular metal sheet structure, similar to a disc, and its data storage capacity is relatively small. In order to increase the data storage capacity of the disk, the current means are often to increase the number of disks and form a multi-layer disk structure to expand the data capacity. However, the existing disk capacity expansion structure increases the connection area and number of connections between the disk and the spindle, resulting in a weakened stability of the spindle drive. After long-term use, when one of the disks is offset, it will affect the data reading function of at least two disks at the same time. For this reason, we propose an external computer memory. Utility Model Content

[0005] As a further solution of the utility model: the lower shell and the upper shell are matched together to form a light-proof cavity inside, and a mounting plate is integrally formed at the top of the motor. The mounting plate is fixed to the inner wall of the upper shell so that the motor is installed in the light-proof cavity. The inner top wall of the upper shell is provided with a positioning groove that is adapted to the mounting plate. By providing the positioning groove, it can be quickly connected to the mounting plate, thereby fixing the motor.
[0006] As a further solution of the utility model: the spherical disk includes one or a combination of the first disk, the second disk, and the third disk. The first disk cooperates with the second disk or the third disk to expand the data storage capacity of the computer memory, which is conducive to storing more data information.
[0007] As a further solution of the utility model: the curvatures of the first disk, the second disk and the third disk are equal. By setting the first disk, the second disk and the third disk with equal curvatures, the risk of collision between different disks can be reduced, which is beneficial to improving the stability of computer memory use.
[0008] As a further solution of the utility model: the radii of the first disk, the second disk and the third disk are distributed in a series of steps, which can maintain stable rotation between different disks and is conducive to reading data on disks at different heights.
[0009] As a further solution of the utility model: the first disk, the second disk and the third disk are integrally formed, and the first disk, the second disk and the third disk respectively have at least two surfaces that can read data. By coating magnetic materials on multiple surfaces of the disks to store data, the data storage capacity can be expanded.
[0010] As a further solution of the utility model: a limit ring is welded on the inner wall of the upper shell, and the limit ring runs through the gap formed by the first disk and the second disk or the second disk and the third disk. The limit ring is a hard circular ring plate, which can prevent the deformed disk from making direct contact with its adjacent disk, thereby reducing the impact of the deformed disk on the adjacent disk and maintaining the stable operation of the computer memory.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model can improve the data storage capacity of a computer memory by providing a spherical disk and a curved pressing plate adapted to the spherical disk. The spherical disk has a larger area than a flat disk of the same radius, and can improve the data storage capacity compared with a traditional disk, thereby enhancing the expansion of the computer's data storage capacity.
[0013] 2. The utility model can further increase the data storage capacity compared with a single-layer spherical disk by providing stepped disks arranged in an arithmetic or geometric progression. By welding a limit ring on the inner wall of the upper shell body that can separate adjacent disks, it can prevent the disk from deforming due to failure and affecting the normal shape and data storage capacity of the adjacent disks, thereby improving the security of the memory data storage.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: an external computer memory, including a lower shell 1 and an upper shell 2 that are adapted to each other, the lower shell 1 and the upper shell 2 serve as a memory protection structure, a motor 5 is fixed to the inner top wall of the upper shell 2, the output end of the motor 5 is fixedly connected to a spherical disk 6 through a main shaft 51, the surface of the spherical disk 6 is coated with a magnetic material, the spherical disk 6 includes a first disk 61, a second disk 62, and a third disk 63, or a combination of several of them, the first disk 61 cooperates with the second disk 62 or the third disk 63 to expand the data storage capacity of the computer memory, which is conducive to storing more data information.
[0021] The first disk 61, the second disk 62 and the third disk 63 have the same curvature. By setting the first disk 61, the second disk 62 and the third disk 63 with the same curvature, the risk of collision between different disks can be reduced, which is beneficial to improving the stability of computer memory use.
[0022] After starting the motor 5, the output end of the motor 5 will drive the spherical disk 6 to rotate in the horizontal direction through the main shaft 51. During the rotation of the spherical disk 6, the data information on its surface is read by the magnetic head 7. The top of the lower shell 1 is connected to a curved pressing plate 8 adapted to the spherical disk 6 through the magnetic head 7. The curved pressing plate 8 is adapted one by one to the several disks included in the spherical disk 6. A cache 9 is installed on the inner wall of the lower shell 1 or the upper shell 2. The cache 9 is used to store data information.
[0023] Preferably, Figure 1 As shown, the lower shell 1 and the upper shell 2 cooperate together to form a light-proof cavity inside, and a mounting plate 4 is integrally formed at the top of the motor 5. The mounting plate 4 is fixed to the inner wall of the upper shell 2 so that the motor 5 is installed in the light-proof cavity. The inner top wall of the upper shell 2 is provided with a positioning groove 3 adapted to the mounting plate 4. By providing the positioning groove 3, it can be quickly connected with the mounting plate 4, so that the motor 5 is fixedly installed.
[0024] Preferably, Figure 4 As shown, the radii of the first disk 61, the second disk 62 and the third disk 63 are distributed in an arithmetic progression in a stepped manner, which can maintain stable rotation between different disks and is conducive to reading data from disks at different heights.
[0025] Preferably, Figure 4 As shown, the first disk 61, the second disk 62 and the third disk 63 are integrally formed, and the first disk 61, the second disk 62 and the third disk 63 respectively have at least two surfaces that can read data. By coating magnetic materials on multiple surfaces of the disks to store data, the data storage capacity can be expanded.
[0026] Preferably, Figure 3 As shown, a limit ring 10 is welded to the inner wall of the upper shell 2. The limit ring 10 passes through the gap formed by the first disk 61 and the second disk 62 or the second disk 62 and the third disk 63. The limit ring 10 is a hard circular ring plate, which can prevent the deformed disk from making direct contact with its adjacent disk, thereby reducing the impact of the deformed disk on the adjacent disk and maintaining the stable operation of the computer memory.
[0027] Working principle: When in use, one side or both sides of the spherical disk 6 are coated with magnetic materials respectively. The spherical disk 6 stores data information through the magnetic material on its surface. By setting the spherical disk 6, the data storage capacity can be increased compared with the traditional round disk. The motor 5 is started, and the output end of the motor 5 pulls the spherical disk 6 to rotate through the main shaft 51. During the rotation, the magnetic head 7 reads the information stored on the surface of the first disk 61, the second disk 62 and the third disk 63. By setting stepped disks arranged in an arithmetic or geometric progression, the data storage capacity can be further increased compared with the single-layer spherical disk 6. By welding a limit ring 10 that can separate adjacent disks on the inner wall of the upper shell 2, it can be avoided that the disk failure deformation affects the normal shape and data storage capacity of the adjacent disks.
