Description

Technical fields:

[0001] This utility model relates to the technical field of computer case power supply products, and specifically to a computer case power supply that facilitates the installation and removal of cooling fans. Background technology:

[0002] The power supply used in current computer cases is a separate product. It is fixed inside the computer case by screws or other means and is exposed on the rear side of the computer case. The external power cord is plugged into the power supply's socket to supply power to the power supply. At the same time, the power supply converts the AC power into several DC power supplies to power the various components in the computer.

[0003] To dissipate heat from the power supply (PS), most modern power supplies come with a built-in fan to cool the heat generated during operation. However, these fans are often integrated into the power supply unit, making removal somewhat cumbersome. Over time, dust accumulation can cause the power supply's fan speed to decrease or even damage it. In such cases, the user usually has to replace the entire power supply. Attempting to repair the fan yourself requires removing the power supply from the computer case, disassembling it, and then attempting to repair the fan – a process that is not only tedious but also carries the risk of damaging the power supply itself.

[0004] To address the aforementioned issues, the following technical solution has been proposed: See Chinese Utility Model Patent No. ZL03277733.7, which discloses a computer power supply with a separate cooling fan. The technical solution includes a power supply body and a cooling fan installed inside the power supply body. A cavity for accommodating the cooling fan is formed along one outer surface of the power supply body. An electrical connection device between the power supply body and the cooling fan is provided on the inner wall of the cavity. The cooling fan is detachably installed in the cavity via a guide device. This technical solution separates the cooling fan from the power supply body, allowing the cooling fan to be freely plugged in and out of the power supply, facilitating manual installation and removal. However, its drawback is that since the cooling fan needs power from the power supply body, a corresponding electrical connection must be established between the two. This technical solution uses a wire plug connection, which is inconvenient for installation or removal, and ultimately still requires screws for fastening.

[0005] In response to this, the inventors have made improvements and proposed the following technical solution. Utility model content:

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a computer case power supply that is easy to install and disassemble.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a computer chassis power supply, comprising: a power supply housing, a chassis power supply body and a cooling fan installed inside the power supply housing, wherein the power supply housing has an outer side surface, and a slot for inserting and accommodating the cooling fan is provided on the outer side surface, and a housing positioning structure and a power supply electrode electrically connected to the chassis power supply body are provided in the slot; the cooling fan is provided with a fan positioning structure that cooperates with the housing positioning structure and a contact electrode corresponding to the power supply electrode; the cooling fan is inserted into the slot from the outside to the inside, and the cooling fan is positioned and installed in the slot by the cooperation of the fan positioning structure and the housing positioning structure, and in this state, the power supply electrode and the contact electrode achieve electrical contact connection.

[0008] Furthermore, in the above technical solution, the cooling fan includes: a fan frame, fan blades pivotally connected to the fan frame, and a drive unit. The fan frame is provided with a fan positioning structure that cooperates with the housing positioning structure and a contact electrode corresponding to the power supply electrode.

[0009] Furthermore, in the above technical solution, the power supply electrode and the contact electrode are electrically connected by an elastic contact method, that is, the power supply electrode or the contact electrode uses an elastic metal probe.

[0010] Furthermore, in the above technical solution, the power supply electrode and the contact electrode are electrically connected by magnetic contact, that is, the power supply electrode and the contact electrode use magnets that can attract each other.

[0011] Furthermore, in the above technical solution, the housing positioning structure and the fan positioning structure adopt a snap-fit ​​structure.

[0012] Furthermore, in the above technical solution, the housing positioning structure and the fan positioning structure adopt a magnetic attraction structure.

[0013] Furthermore, in the above technical solution, the power supply housing is a cuboid, and the plates on its left and right sides are formed with cutting portions. The cutting portions are bent inward by cutting to form the slots. The cutting portions include: a baffle for limiting the side of the cooling fan, a support strip for supporting the cooling fan, and a limiting plate for limiting the height of the cooling fan.

[0014] Furthermore, in the above technical solution, the outer side of the power supply housing is provided with a chassis power socket, a chassis power switch and evenly distributed heat dissipation holes; the top surface of the power supply housing is provided with air holes; and the rear side of the power supply housing is provided with cable management holes.

[0015] Furthermore, in the above technical solution, the outer side of the fan frame of the cooling fan is provided with a handle that is easy to pull out.

[0016] Furthermore, in the above technical solution, a limiting structure is provided at the end of the slot to block the cooling fan.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] 1. This utility model independently sets up the cooling fan in the power supply of a computer case. A slot is directly opened on the outer side of the power supply casing, and the cooling fan is directly installed in the slot through a plug-in connection. Since the slot is located directly on the outer side of the computer casing, after the power supply is installed on the computer case, the outer side of the computer casing is directly exposed on the surface of the computer case. Users can install or remove the cooling fan in the power supply without disassembling the computer case.

[0019] 2. In order to facilitate disassembly and assembly, this utility model does not use the conventional plug connection method. Instead, contact electrodes are directly set on the cooling fan and power supply electrodes are set on the power supply housing. When the cooling fan is installed in the designated position, the contact electrodes and power supply electrodes are directly connected through electrical contact to realize the power supply line connection without the need for an additional conductive plug connection method.

[0020] 3. In order to position the cooling fan, the present invention uses a positioning structure between the cooling fan and the slot to achieve the positioning of the cooling fan and the slot. These positioning structures can adopt magnetic attraction, elastic buckle or other methods, which facilitates insertion and removal, while providing sufficient stability and restraint to ensure stable assembly of the cooling fan.

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] This utility model relates to a power supply for a computer case. (See attached image) Figure 1 As shown, the main body of the computer case 6 is rectangular. The power supply 100 is installed inside the case 6, and the outer side 11 of the power supply 100 is directly exposed on the rear surface 61 of the case 6, which facilitates direct operation of the power supply 100. The outer side 11 of the power supply 100 is usually provided with a power plug 111, a power switch 112, and evenly distributed ventilation holes 113.

[0030] See Figure 2 As shown, the computer case power supply 100 includes: a power supply housing 1, a power supply body 2 and a cooling fan 3 installed inside the power supply housing 1. In order to enable the installation and removal of the cooling fan 3 without opening the computer case 6, a slot 10 is provided on the outer side 11 of the power supply housing 1 for inserting and accommodating the cooling fan 3, and a housing positioning structure 4 and a power supply electrode 5 electrically connected to the power supply body 2 are provided in the slot 10.

[0031] The cooling fan 3 includes: a fan frame 31, fan blades 32 pivotally connected to the fan frame 31, and a drive unit 33. The fan frame 31 is provided with a fan positioning structure 34 that cooperates with the housing positioning structure 4 and a contact electrode 35 corresponding to the power supply electrode 5.

[0032] The cross-sectional shape of the slot 10 matches the cross-sectional shape of the cooling fan 3, allowing the cooling fan 3 to be inserted into the slot 10. To achieve positioning between the cooling fan 3 and the slot 10, a positioning structure is provided between them, namely, a housing positioning structure 4 is provided inside the slot 10, and a fan positioning structure 34 that cooperates with the housing positioning structure 4 is provided on the fan frame 31.

[0033] The housing positioning structure 4 and the fan positioning structure 34 can adopt the following positioning methods:

[0034] Method 1: A raised elastic latch is provided on the side wall of slot 10 as a housing positioning structure 4. The fan frame 31 has a corresponding slot on its side wall that engages with the elastic latch as a fan positioning structure 34. The positioning of the cooling fan 3 and slot 10 is achieved through the engagement of the elastic latch and the slot. For example, since the power supply housing 1 is usually made of sheet metal, cut portions can be formed on the opposite left and right sides of the power supply housing 1. These cut portions are then bent inward to form the slot 10, which is used to limit the side baffle of the cooling fan 3. A latch is formed by stamping, and the latch utilizes the elasticity of its own material to form a certain elastic deformation. The fan frame 31 is usually made of plastic material by injection molding, and the slot is integrally formed during injection molding. When the cooling fan 3 is inserted into the designated position along the slot 10, the latch falls into the slot, forming a positioning engagement, thereby fixing the cooling fan 3 in the slot 10.

[0035] Method 2: The housing positioning structure 4 and the fan positioning structure 34 adopt a magnetic positioning structure. Combined with... Figure 3 As shown, a first magnet is provided on each side of the slot 10 as a housing positioning structure 4, and a second magnet is provided on the fan frame 31 at the position corresponding to the first magnet as a fan positioning structure 34. The first magnet and the corresponding second magnet are attracted to each other. When the cooling fan 3 is inserted into the designated position along the slot 10, the magnetic attraction between the first magnet and the second magnet positions and fixes the cooling fan 3 in the slot 10.

[0036] In addition, combined Figure 2 As shown, to prevent the cooling fan 3 from being over-inserted, a limiting structure 101 is provided at the end of the slot 10. This limiting structure 101 can be a stop block protruding from the end of the slot 10, which blocks the cooling fan 3, prevents the cooling fan 3 from being over-inserted, and forms a limit.

[0037] To achieve electrical connection between the cooling fan 3 and the power supply unit 2 inside the power supply unit 100, thereby supplying power to the cooling fan 3, this utility model adopts the following method: combining Figure 2 , Figure 3 As shown, a power supply electrode 5 is provided on the power supply housing 1, and the power supply electrode 5 is connected to the chassis power supply body 2 in the chassis power supply 100 via a wire. A contact electrode 35 is provided on the cooling fan 3, and the contact electrode 35 is connected to the drive unit 33 via a wire. When the cooling fan 3 is positioned and fixed in the slot 10, the power supply electrode 5 and the contact electrode 35 are electrically connected, thereby supplying power to the cooling fan 3 through the chassis power supply body 2 in the chassis power supply 100.

[0038] The power supply electrode 5 and the contact electrode 35 can be positioned in the following ways:

[0039] Method 1: The power supply electrode 5 and the contact electrode 35 are electrically connected using an elastic contact method. For example, the power supply electrode 5 is a commonly used elastic metal probe, and the contact electrode 35 is a metal conductive sheet. When the cooling fan 3 is positioned and fixed in the slot 10, the elastic metal probe, which serves as the power supply electrode 5, elastically presses against the metal conductive sheet, which serves as the contact electrode 35, thereby achieving an electrical connection.

[0040] Typically, the power supply electrode 5 is located on the inner side 14 of the power supply housing 1 opposite to the outer side 11. The contact electrode 35 is located on the side of the fan frame 31 insertion end in the cooling fan 3. Of course, the power supply electrode 5 can also be located on the left (or right) side wall of the slot 10, and the contact electrode 35 on the left (or right) side of the fan frame 31.

[0041] Method 2: The power supply electrode 5 and the contact electrode 35 are electrically connected by magnetic attraction, that is, magnets that can attract each other are used in the power supply electrode 5 and the contact electrode 35. A stable connection between the power supply electrode 5 and the contact electrode 35 is achieved through magnetic attraction.

[0042] See Figure 4 As shown, this is a second embodiment of the present invention. To facilitate the insertion and removal of the cooling fan 3, a handle 310 for easy pulling is provided on the outside of the fan frame 31 of the cooling fan 3. The user can easily pull the cooling fan 3 out of the slot 10 using the handle 310.

[0043] See Figures 5 to 7 As shown, this is Embodiment 3 of the present invention. Embodiment 3 is a practical application structure of the present invention. The power supply housing 1 is cuboid in shape, comprising: an outer side 11, left and right side panels 12, a top surface 13, an inner side panel 14, and a bottom surface 15. These sides, made of metal sheet, surround and form the power supply housing 1. The outer side 11 has a through hole serving as the port of the slot 10, and the outer side 11 is provided with a chassis power socket 111, a chassis power switch 112, and evenly distributed heat dissipation holes 113.

[0044] The left and right sides of the plate are formed with cutting portions 120, which are bent inward by cutting to form the slots 10. Specifically, the cutting portion 120 includes: a baffle 121 for defining the side of the cooling fan 3, a support strip 122 for supporting the cooling fan 3, and a limiting plate 123 for limiting the height of the cooling fan 3.

[0045] The top surface 13 of the power supply housing has vents 130, which correspond to the positions of the fan blades 32 in the cooling fan 3 to facilitate airflow.

[0046] The power supply housing 1 has a cable harness hole 140 on its rear side 14. The cable harness connected to the power supply body 2 can extend out from the cable harness hole 140 and be plugged into various components in the computer.

[0047] Combination Figure 1 As shown, the installation method of this embodiment three is as follows:

[0048] First, install the entire power supply 100 onto the computer case 6, and expose the outer side 11 of the power supply 100 on the surface of the case 6.

[0049] Secondly, the cooling fan 3 is inserted into the power supply housing 1 through the slot 10. When the cooling fan 3 is inserted into the slot 10 from the outside to the inside, the positioning structure between the cooling fan 3 and the slot 10 is used to position the cooling fan 3 and the slot 10. At the same time, in this state, the contact electrode 35 on the cooling fan 3 and the power supply electrode 5 on the power supply housing 1 are electrically connected, so that the cooling fan 3 is powered by the main body 2 of the power supply housing 100.

[0050] When it is necessary to replace or clean the cooling fan 3, simply pull the cooling fan 3 out of the slot 10 exposed on the surface of the computer case 6 under the action of external force to overcome the positioning connection between the cooling fan 3 and the slot 10.

[0051] This utility model has a simple structure and can quickly replace and repair the cooling fan in the power supply of the chassis.

[0052] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
