Description

Technical Field

[0001] This utility model relates to the field of circuit board chassis technology, specifically to a modular structure circuit board chassis. Background Technology

[0002] With the rapid development of information technology, the performance of electronic devices such as computers, servers, and communication equipment is constantly improving, and their functions are becoming increasingly complex. As the core components of these devices, the number and density of circuit boards are also constantly increasing.

[0003] Currently, in existing modular chassis, the arrangement of structural boards is often quite compact, with small gaps between adjacent boards and between the structural boards on both sides and the side walls of the chassis. Therefore, it is inconvenient to disassemble and maintain the structural boards, either as a whole or in parts.

[0004] Therefore, existing technologies often utilize specialized tools (such as long-handled screwdrivers, thin pliers, etc.).

[0005] While this method allows for card removal in confined spaces, it not only increases the difficulty for users but also requires specialized tools at a higher cost and carries the risk of damaging the card. Utility Model Content

[0006] The purpose of this utility model is to provide a modular structure board chassis to solve the technical problem of operational risks caused by using tools to remove the boards in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0008] A modular board chassis includes a front card slot frame and a rear card slot frame, with a backplate frame between the front and rear card slot frames. A chassis fan and a power module are disposed within the front and rear card slot frames. Square through holes are provided on both side walls of the front and rear card slot frames. An opening is provided on the side of the square through hole away from the backplate frame to communicate with the outside, forming a notch. A baffle is rotatably disposed within the notch, and the baffle is rotatably mounted on the front and rear card slot frames via a one-way rotating component.

[0009] As a preferred embodiment of this utility model, a fixed mounting frame is movably provided on both sides of the front card insertion frame and the rear card insertion frame, the two ends of the fixed mounting frame are movably connected to the front card insertion frame or the rear card insertion frame, and the middle part of the fixed mounting frame contacts the baffle.

[0010] As a preferred embodiment of this utility model, portable installation handles are movably provided on both sides of the front card insert frame and the rear card insert frame, respectively. The two ends of the portable installation handles are movably connected to the front card insert frame or the rear card insert frame, and the middle part of the portable installation handles contacts the baffle.

[0011] As a preferred embodiment of this utility model, the chassis fan includes a front chassis fan and a rear chassis fan. The front chassis fan is located at the bottom layer inside the front expansion card frame, and the rear chassis fan is located at the bottom layer inside the rear expansion card frame. The power module is located on one side inside the front expansion card frame.

[0012] As a preferred embodiment of this utility model, the chassis fan includes a front chassis upper fan, a front chassis lower fan, and a rear chassis fan. The front chassis upper fan and the front chassis lower fan are respectively located at the top and bottom layers inside the front expansion card frame, and the rear chassis fan and the power module are respectively located at the top and bottom layers inside the rear expansion card frame.

[0013] As a preferred embodiment of this utility model, the bottom of the front card insertion frame and the rear card insertion frame are respectively provided with support feet.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention provides notches on both sides of the front and rear card frames, which widens the gap between the structural cards and the chassis when the baffle rotates outward. This allows the side panel cards to be manually removed from the outside, and the internal cards to be taken out one by one, without the need for special tools to operate in the narrow gap. This improves the convenience of operation and reduces the operating cost and the risk of damage to the cards. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a modular structure board chassis, including a front card frame 1 and a rear card frame 2. A back plate frame 3 is provided between the front card frame 1 and the rear card frame 2. A chassis fan and a power module 11 are provided inside the front card frame 1 and the rear card frame 2. Square perforations are provided on both sides of the frame walls of the front card frame 1 and the rear card frame 2. An opening is provided on the side of the square perforation away from the back plate frame 3 to communicate with the outside, forming a notch 4. A baffle 5 is rotatably installed in the notch 4. The baffle 5 is rotatably mounted on the front card frame 1 and the rear card frame 2 through a one-way rotating part 6.

[0026] This modular chassis is designed with a front card frame 1 and a rear card frame 2 to accommodate structural boards with front and rear cards. In actual use, the backplate is set in the backplate frame 3, and the front and rear cards are connected to the backplate in the front card frame 1 and the rear card frame 2 respectively to form an integrated structure for use, thereby providing reliable hardware assistance for devices that need to perform complex calculations.

[0027] In practical use, as an example, the baffle 5 can be fixedly installed on the front card holder frame 1 and the rear card holder frame 2 with bolts. When it is not necessary to remove the card, the baffle 5 is fixed in place with bolts, and the baffle 5 closes the notch 4. When it is necessary to remove the card, the bolts are removed, the baffle 5 is rotated to open the notch 4, and then the panel of the card can be manually grasped from the outside to remove it (not shown in the figure).

[0028] Furthermore, as shown in the figure, in this device, as an embodiment two, fixed mounting frames 7 are movably arranged on both sides of the front card insertion frame 1 and the rear card insertion frame 2. The two ends of the fixed mounting frames 7 are movably connected to the front card insertion frame 1 or the rear card insertion frame 2 by bolts. The middle part of the fixed mounting frames 7 contacts the baffle 5 to limit the baffle 5 and prevent it from rotating outwards. On one hand, the fixed mounting frames 7 can limit the baffle 5; in use, by removing the fixed mounting frames 7, the baffle 5 can be rotated to open the notch 4. On the other hand, the fixed mounting frames 7 can also serve as mounting components to fix the entire device onto a bracket or platform to adapt to different usage scenarios.

[0029] like Figure 3 As shown in Embodiment 3, portable mounting handles 8 are movably provided on both sides of the front card insert frame 1 and the rear card insert frame 2. The two ends of the portable mounting handles 8 are movably connected to the front card insert frame 1 or the rear card insert frame 2, and the middle part of the portable mounting handles 8 contacts the baffle 5. The portable mounting handles 8 are similar in configuration to the fixed mounting frame 7, and can be movably mounted on the front card insert frame 1 or the rear card insert frame 2 by bolts. The contact between the middle part of the portable mounting handles 8 and the baffle 5 serves to limit its movement. Compared to the fixed mounting frame 7, the portable mounting handles 8 not only limit the movement of the baffle 5 but also allow the entire device to be portable and movable, thus increasing its overall flexibility of use.

[0030] Furthermore, depending on the different chassis size and type, the positions of the fans and power supply module 11 inside the chassis can also be configured in different ways. For example, such as Figure 4 As shown, for a chassis that is compatible with 3U cards, the chassis fans in the front card frame 1 and the rear card frame 2 may include a front chassis fan 9 and a rear chassis fan 14. The front chassis fan 9 is located at the bottom of the front card frame 1, and the rear chassis fan 14 is located at the bottom of the rear card frame 2. The power module 11 is located on one side inside the front card frame 1.

[0031] like Figure 5As shown, for a vertically inserted chassis that adapts to 6U cards, the chassis fans in the front card frame 1 and the rear card frame 2 include a front chassis upper fan 12, a front chassis lower fan 13 and a rear chassis fan 14. The front chassis upper fan 12 and the front chassis lower fan 13 are respectively located at the top and bottom layers inside the front card frame 1, and the rear chassis fan 14 and the power module 11 are respectively located at the top and bottom layers inside the rear card frame 2.

[0032] In addition, the bottom of the front card holder 1 and the rear card holder 2 are respectively provided with support feet 10, which makes the device more stable to use.

[0033] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
