A fan unit panel assembly and a communication device having the same

Abstract

This application relates to a fan unit panel assembly and a fan unit for a communication device. The fan unit panel assembly is divided into a support, a U-shaped panel, a fan unit connector, an elastic element, and a limiting element. The fan unit connector is connected to the support via the elastic element and is installed inside the panel. When the airflow changes, the panel height changes accordingly. At this time, a limiting element of appropriate length is placed in the gap between the inner wall of the panel and the fan unit connector to achieve the limiting and fixing of the fan unit connector. This makes the fan unit connector and the elastic element interchangeable, eliminating the need for remanufacturing. Only the support and the limiting element need to be replaced accordingly. Ultimately, this results in a fan unit panel assembly with fewer parts, simpler assembly, lower mold costs, and lower material costs.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] It should be understood in connection with this application that:

[0039] In the telecommunications industry, system equipment typically utilizes adjustable fan unit height to improve heat dissipation efficiency due to cooling requirements. This adjustment necessitates a corresponding adjustment of the fan unit's panel assembly height. (Refer to...) Figure 1 and Figure 2 As shown, Figure 1 The diagram shows the overall connection between the fan unit panel assembly C and the fan unit D. Figure 2 The fan unit panel assembly shown includes structural components such as button bracket a, button with locking pin b, panel support c, end cap d, decorative strip e, and panel f. The height of the above structural components is strongly related to the height of the fan unit panel assembly. When the airflow changes, the height of the fan unit panel assembly needs to be adjusted, and each of its structural components needs to be remanufactured using new molds, which is inconvenient for height adjustment. Therefore, the existing fan unit panel assembly has poor material versatility, high mold costs, and high material costs.

[0040] Therefore, this application provides a fan unit panel assembly and a fan unit for a communication device to solve the problem in the related art that each structural component of the fan unit panel assembly needs to be re-molded and manufactured when the airflow changes, resulting in poor versatility and high cost.

[0041] Please see Figures 3-7 As shown, a fan unit panel assembly includes:

[0042] Support 1 is fixed inside panel 2; panel 2 has a U-shaped cross-section.

[0043] The fan unit connector 3 is connected to the bracket 1 via the elastic member 4 and is used to be installed inside the panel 2;

[0044] Multiple limiting members 5 of unequal lengths are provided. In the height direction of the panel 2, the multiple limiting members 5 are selectively provided in the gap according to the distance between the inner wall of the panel 2 and the fan unit connector 3, so as to limit the fan unit connector 3 in the height direction.

[0045] The fan unit panel assembly is divided into a bracket 1, a U-shaped panel 2, a fan unit connector 3, an elastic element 4, and a limiting element 5. The fan unit connector 3 is connected to the bracket 1 through the elastic element 4 and is used to be installed inside the panel 2. When the airflow changes, the height of the panel 2 changes accordingly. At this time, a limiting element 5 of appropriate length is placed in the gap between the inner wall of the panel 2 and the fan unit connector 3 to achieve the limiting and fixing of the fan unit connector 3. This allows the fan unit connector 3 and the elastic element 4 to be interchangeable without remanufacturing. Only the bracket 1 and the limiting element 5 need to be replaced accordingly. Ultimately, this results in a fan unit panel assembly with fewer parts, simpler assembly, lower mold costs, and lower material costs.

[0046] In some preferred embodiments, the specific limiting form of the limiting member 5 is configured as follows:

[0047] In the first case, the top of the fan unit connector 3 contacts the inner top wall of the panel 2, and a limiting member 5 is provided between the bottom of the fan unit connector 3 and the inner bottom wall of the panel 2.

[0048] The second type is provided with a limiting member 5 between the top of the fan unit connector 3 and the inner top wall of the panel 2, and a limiting member 5 is also provided between the bottom of the fan unit connector 3 and the inner bottom wall of the panel 2.

[0049] Both of the above methods involve changing the length of the limiting member 5 to achieve the universality of the fan unit connector 3. The only difference is the number of limiting members 5 required, which can be selected according to the needs.

[0050] The above-mentioned limiting component 5 does not specify whether it is fixedly connected to panel 2 or to fan unit connector 3. Therefore, the following settings are made to distinguish between them:

[0051] Form 1 is formed based on the second type of limiting form of limiting component 5, see attached document. Figure 4 -Appendix Figure 7 :

[0052] The limiting component 5 includes a pin; the pin is used to fix it to the inner wall of the panel 2. At this time, the corresponding fan unit connector 3 includes a latch 301 and a pressing block 300 connected to each other; in the height direction of the panel 2, the pressing block 300 is provided with horizontal guide rails 302 on the upper and lower sides, and the horizontal guide rails 302 are provided with guide grooves that are slidably connected to the pin; the end of the pin that contacts the guide groove is spherical.

[0053] The pins on the upper and lower sides of panel 2, together with the guide grooves on both sides of fan unit connector 3 and elastic element 4, guide the action of pressing fan unit connector 3. After the fan unit connector 3 is released, it resets, which facilitates the installation of fan unit panel assembly. The pin head is designed with a spherical structure to reduce sliding friction and improve the pressing feel.

[0054] Among them, reference appendix Figure 4 As shown, bracket 1 is an L-shaped bracket; the L-shaped bracket is connected to panel 2 by screws, and a plug rod 6 is provided on it; an elastic element 4 is sleeved on the plug rod 6;

[0055] The elastic element 4 is a spring; the spring is sleeved on the insert rod 6; the pressing block 300 has a receiving groove; the receiving groove accommodates the insert rod 6 and the elastic element 4. This embodiment describes the specific cooperation between the elastic element 4 and the fan unit connector 3, realizing the pressing action. However, there is a problem of the fan unit connector 3 falling off because it is not fixedly connected to the elastic element 4. Therefore, the following settings are also made for the panel 2:

[0056] Two guide rail baffles 200 are provided at both ends along the length of panel 2, and the guide rail baffles 200 at each end are distributed on the inner top wall and inner bottom wall of panel 2.

[0057] The space formed between the two guide rail baffles 200 at each end allows the pressing block 300 to pass through. By blocking the horizontal guide rail 302 with the guide rail baffles 200, the problem of the fan unit connector 3 falling off is prevented.

[0058] Form two is formed based on the first type of limiting form of the limiting component 5:

[0059] The fan unit connector 3 includes a latch 301 and a pressing block 300 connected together; the limiting member 5 includes a pin; the pin is fixedly connected to the pressing block 300; the end of the pin that contacts the panel 2 is spherical.

[0060] Bracket 1 is an L-shaped bracket, which is connected to panel 2 by screws;

[0061] Elastic element 4 connects the pressing block 300 and the vertical surface of the L-shaped bracket;

[0062] The elastic element 4 is a spring, and the two ends of the spring are fixedly connected to the pressing block 300 and the L-shaped bracket, respectively.

[0063] The above elastic element 4 is directly fixedly connected to the pressing block 300 and the L-shaped bracket, so there is no problem of the fan unit connector 3 falling off. Therefore, the number of structural components in this solution is less.

[0064] For installation steps of each component of the fan unit panel assembly, please refer to the attached document. Figure 5 -Appendix Figure 7:

[0065] Step 1: Align the pressing block 300 with the panel pins and install it from the middle of panel 2 outwards to both sides;

[0066] Step 2: Insert the spring into the receiving groove in the pressing block 300, and then insert the rod 6 into the spring;

[0067] Step 3: Install bracket 1 and tighten it with two screws to limit the movement of the spring and pressing block 300.

[0068] Based on the above, refer to Table 1 below, and the appendix. Figure 8 .

[0069] To accommodate fan units of different heights, the versatility of the fan unit panel using this solution is as follows:

[0070]

[0071] Table 1

[0072] Reference Appendix Figure 8 Considering the requirements of ergonomic operation and ease of use, the height of fan unit connector 3 is set to A'; the corresponding minimum height of the fan unit panel is A=A'+3.2mm; reference mark E'.

[0073] With the button height A' set unchanged, fan units with different panel heights can be obtained by adjusting the length of the rivet pins on the top and bottom sides of panel 2; the standard length specification of the rivet pin is usually 2mm with a standard step distance, so the achievable fan unit panel height B = A + 4x; refer to mark E''.

[0074] This technical solution can be used not only for fan units but also for other modules requiring tool-free plugging and unplugging. When applied to other modules, the length of the rivet pins can be customized if necessary to achieve more flexible height adjustment, i.e., B=A+2x or B=A+x.

[0075] The effects of the improvements can be seen in Table 2 below:

[0076]

[0077] Table 2

[0078] This application also proposes, with reference to Figure 9 As shown, a fan unit of a communication device includes: the above-mentioned fan unit panel assembly.

[0079] Due to the versatility of the fan unit panel assembly, it allows for flexible adjustment of the fan unit height to regulate airflow and improve heat dissipation efficiency, meeting the needs of heat dissipation functions. Furthermore, this fan unit panel assembly has fewer parts, is simpler to assemble, requires less mold investment, and has lower material costs. Figure 9 The fan unit panel assembly is marked E, and the fan unit is marked D;

[0080] Fan unit connector 3 is located at both ends of the panel, providing tool-free unlocking and disassembly / removal functions for the fan unit;

[0081] The bracket 1 is a button stop structure designed to meet the pressing stroke limit of the fan unit connector 3; the panel 2 serves as the main structure of the fan unit panel assembly, providing both the appearance and function of the fan unit, and also acting as the carrier for the fan unit connector 3 and the fan indicator light.
