Description

Technical Field

[0001] This utility model belongs to the field of computer chassis technology, and in particular relates to a floating mounting structure for desktop computer motherboards. Background Technology

[0002] Desktop computers typically consist of a relatively independent host, monitor, and other components, requiring placement on a computer desk or dedicated workbench, hence the name "desktop computer." The computer case, as part of the computer's components, primarily serves to house and secure these components, providing support and protection. Furthermore, the computer case plays a crucial role in shielding against electromagnetic radiation. The motherboard is one of the most basic and crucial components of a computer. It is generally a rectangular circuit board containing the main circuitry of the computer, typically including a BIOS chip, I / O control chip, keyboard and front panel control switch interfaces, indicator light connectors, expansion slots, and DC power supply connectors for the motherboard and expansion cards. Traditionally, computer cases use screws to connect the motherboard to the motherboard bracket, with a fixed distance between the motherboard and the bracket. When adjusting wiring or motherboard position, the motherboard must be removed, adjusted, and then reinstalled, slowing down the adjustment process and reducing the efficiency of computer component installation.

[0003] Chinese utility model patent application number 201920534550.X discloses a computer chassis that is easy to install and disassemble. The chassis includes a front panel, a chassis body fixedly connected to the right side of the front panel, a first baffle fixedly connected to the top of the chassis body's inner cavity, a second baffle fixedly connected to the left side of the bottom of the first baffle, a left side of the second baffle fixedly connected to the front panel, and a third baffle fixedly connected to the right side of the chassis body's inner cavity. This design, through the coordinated use of a fixing rod, a rotating sleeve, a damping spring, a slot, a locking block slot, a pull rod, a locking block, a spring, a plug, and a locking slot, solves the problem of slow computer chassis disassembly speed, but it is not suitable for floating motherboard installations. Utility Model Content

[0004] The purpose of this utility model is to provide a floating mounting structure for desktop computer motherboards, overcoming the shortcomings of the prior art. It is suitable for motherboard installation in desktop computers. After the motherboard and motherboard bracket are installed, there is a small gap between them with elastic movement space. When the position of the motherboard needs to be changed, pushing the motherboard can increase or decrease the gap between the motherboard and the motherboard bracket without removing the motherboard, thereby improving the efficiency of computer installation or maintenance.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A floating mounting structure for a desktop computer motherboard includes a cylindrical base, a cap, a floating rod, an upper ring magnet, a lower ring magnet, and a middle magnet. The cylindrical base is a cylindrical body with an open top. The lower ring magnet is fixedly connected to the bottom of the cylindrical base. The cap is connected to the top of the cylindrical base, and the upper ring magnet is fixedly connected inside the cap. The floating rod is coaxially arranged with the cylindrical base. The top of the floating rod is connected to the middle magnet through a set screw. The middle magnet is located between the upper ring magnet and the lower ring magnet. The magnetic pole directions of adjacent magnets are the same. The bottom of the floating rod is provided with an internal threaded hole for connection with the motherboard.

[0007] Furthermore, the periphery of the cylinder seat is provided with mounting threaded holes.

[0008] Furthermore, the bottom of the mounting threaded hole is provided with a positioning recess, which is deformed to match the bottom of the countersunk hole on the motherboard bracket.

[0009] Furthermore, a guide ring is provided at the interface between the floating rod and the cylinder seat.

[0010] Furthermore, the outer edge of the intermediate magnet is provided with a slip ring, and the outer surface of the slip ring is fitted with the inner wall of the cylinder seat.

[0011] Furthermore, the guide ring and / or slip ring are polytetrafluoroethylene rings.

[0012] Furthermore, there are two mounting threaded holes, arranged symmetrically on the left and right sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) Suitable for motherboard installation in desktop computers. After the motherboard and motherboard bracket are installed, there is a small gap between them with flexible movement space. When the position of the motherboard needs to be changed, the gap between the motherboard and the motherboard bracket can be increased or decreased by pushing the motherboard without removing the motherboard, thereby improving the efficiency of computer installation or repair.

[0015] 2) This structure is also suitable for other installation scenarios where a small vertical displacement is required after installation. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] To more clearly illustrate the specific embodiments of this utility model or the technical solutions in the prior art, the specific embodiments used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the specific embodiments described below are some embodiments of this utility model. For those skilled in the art, other specific embodiments can be obtained based on these specific embodiments without creative effort.

[0023] The components of the present invention described and shown in the specific embodiments herein can be arranged and designed in numerous different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the specific embodiments is not intended to limit the scope of the claimed invention, but only to illustrate selected embodiments of the invention.

[0024] See Figure 1-4 This is a schematic diagram of an embodiment of a floating mounting structure for a desktop computer motherboard according to this utility model. It includes a cylindrical base 1, a cap 2, a floating rod 3, an upper ring magnet 4, a lower ring magnet 5, and a middle magnet 6. The cylindrical base 1 is a cylindrical body with an open top. The lower ring magnet 5 is fixedly connected to the bottom of the cylindrical base 1. The cap 2 is connected to the top of the cylindrical base 1, and the upper ring magnet 4 is fixedly connected inside the cap 2. The floating rod 3 is coaxially arranged with the cylindrical base 1. The top of the floating rod 3 is connected to the middle magnet 6 via a set screw 7. The middle magnet 6 is located between the upper ring magnet 4 and the lower ring magnet 5. The magnetic poles of adjacent magnets have the same direction, and like poles repel each other, thus keeping the middle magnet 6 between the upper ring magnet 4 and the lower ring magnet 5. The components can be used as a standard part after assembly. The bottom of the floating rod 3 has an internal threaded hole 12 for connection with the motherboard 8.

[0025] In use, the base 1 is connected to the main board frame 9 via countersunk screws, and the main board 8 is connected to the end of the floating rod 3 via screw 10. When it is necessary to change the distance between the main board 8 and the main board frame 9, an external force pulls or presses the main board 8 up or down, causing the floating rod 3 to be pulled out or retracted. The middle magnet 6 moves closer to or away from the downward ring magnet 5 under the action of the floating rod 3, thereby achieving a small-distance movement effect. When the external force is removed, the floating rod 3 resets under the action of magnetic force until it returns to its initial centered position.

[0026] The periphery of the cylinder base 1 is provided with mounting threaded holes 11. The bottom of the mounting threaded holes 11 is provided with a positioning recess, which matches the bottom deformation of the countersunk hole on the main board bracket 9, so as to achieve quick positioning and installation. There are two mounting threaded holes 11, which are symmetrically arranged on the left and right sides. The periphery of the cylinder base 1 is minimized to reduce the volume and weight.

[0027] A guide ring 13 is provided at the mating point between the floating rod 3 and the cylinder seat 1. A slip ring 14 is provided on the outer edge of the intermediate magnet 6, and the outer surface of the slip ring 14 mates with the inner wall of the cylinder seat 1. Both the guide ring 13 and the slip ring 14 are made of polytetrafluoroethylene (PTFE) to reduce frictional resistance and improve the floating effect of the main plate.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
