Description

Rotating slow lift accessories

The present invention provides a rotation slow lifting accessory, in particular, a damping assembly installed on a chassis and a contact assembly installed on a circuit board tray. When the circuit board tray rotates on the chassis, the docking body of the damping assembly and the first lever or the second lever of the contact assembly produce contact displacement, which can produce a slow-down or slow-up damping and blocking effect when the circuit board tray rotates close to the horizontal or vertical angle, thereby avoiding vibration generated during the rotation process and the phenomenon of over-turning of the horizontal and vertical angles.

With the continuous innovation and progress of computer technology, the application of computers or various electronic and electrical products has become more extensive, and the functions of use have continued to expand and increase. In computers or electronic and electrical products, the circuit layout, central processing unit, chip and various electronic components used to process various operations, calculations, execution, analysis and other functions must also be appropriately expanded and increased. Therefore, the configuration of circuit layout, central processing unit, chip and various electronic components Circuit boards for components will also expand their area and scope as the application functions of computers increase; however, given the limited available space inside computers or electronic and electrical products, the circuit boards that control the startup and operation of computers or electronic and electrical products cannot be expanded. To solve the problem of circuit board application, server rooms will assemble multiple layers of circuit boards inside the server chassis to meet the increasingly powerful server operations.

Furthermore, some circuit boards currently used are fixed in the chassis by screw locking, and the screws are passed through the holes on the frame and then aligned and locked into the screw holes of the circuit board. This screw locking method not only requires the use of a large number of screws, but also requires the removal and installation of multiple screws one by one before disassembly and installation, resulting in a long assembly time and a significant increase in downtime maintenance time. If the chassis is filled with interface cards, memory storage devices, power cables, cables and other components, it will require tools to be inserted for locking. The action is very inconvenient and may even cause the screw to fall off and be lost during the locking period. If the screw is not the right size and is locked with force, it is easy to damage the screw hole on the circuit board, which is not conducive to assembly or disassembly. In addition, some manufacturers have designed a shaft structure inside the small server to store or flip the machine box with multiple circuit boards to the outside of the server for easy maintenance. Since the shaft structure is pressed by the gravity of the machine box, it is easy to generate greater friction when rotating, which causes metal powder to be generated at the shaft. At the same time, it is known that when the shaft is not equipped with any damping mechanism, it is easy to produce excessive vibration and over-turning during the rotation process, and even cause the locking structure between the circuit board and the chassis to be loosened and separated. The various defects caused by the fixing mechanism of the circuit board of the aforementioned server are the direction that the relevant manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed the invention of this rotary slow-lift accessory.

When the rotation position of the circuit board tray 4 and the chassis 3 is close to the horizontal position, the first supporting edge 22 of the first lever 22 is 2 forms contact and resistance with the docking body 123 of the damping plate 12 again (as shown in Figure 11). When the circuit board tray 4 continues to descend and rotate to the horizontal position, the first lever 22 pushes the docking body 123 of the damping plate 12 back from the second position to the first position in a rotational manner and forms a blocking effect. The elastic member 1213 of the damping plate 12 and the elastic resistance of the housing 11 are converted to form a slow-down damping, which can also prevent the circuit board tray 4 from flipping over on the chassis 3 and generating unnecessary vibration.

The main features of the invention are the damping assembly 1 installed on the chassis 3 and the contact assembly 2 installed on the circuit board tray 4. When the circuit board tray 4 rotates on the chassis 3, the docking body 123 of the damping assembly 1 and the first lever 22 or the second lever 23 of the contact assembly 2 produce contact displacement, which can produce a slow-down or slow-up damping and blocking effect when the circuit board tray 4 rotates close to the horizontal or vertical angle, thereby avoiding vibration and horizontal and vertical angle over-shifting during the rotation process. This invention is extremely practical when applied to server room equipment, so a patent application is filed to seek patent protection.
