Description

Technical Field

[0001] This utility model relates to the field of switching power supply technology, specifically a suspended switching power supply. Background Technology

[0002] A switching power supply is a highly efficient power conversion device that uses modern power electronics technology to control and stabilize the output voltage by rapidly switching electronic components (such as transistors). Switching power supplies are widely used in various electronic devices and are an indispensable part of modern electronic technology.

[0003] Due to structural and installation limitations, switching power supplies are often fixed to the side walls of equipment such as chassis and cabinets with screws. This installation method will directly transmit the mechanical vibration and vibration from accidental impacts on the equipment to the power supply body, which can easily cause damage. In addition, it is inevitable that one side will be in contact with the side wall of the equipment, which will affect the heat dissipation effect.

[0004] Therefore, in order to solve the above problems, we propose a suspended switching power supply. Utility Model Content

[0005] The purpose of this invention is to provide a suspended switching power supply that solves the problems mentioned in the background art through flexible suspension and vibration reduction measures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a suspended switching power supply, comprising a power supply body and a pair of cantilever arms, wherein buffers are fixedly installed at the center of both sides of the power supply body, and a docking groove is provided at one end of each cantilever arm, wherein the buffers on the same side are inserted into the docking grooves, a crossbeam is fixedly installed at the end of one cantilever arm away from the docking groove, and the end of the other cantilever arm away from the docking groove is connected to the crossbeam through a snap-fit ​​structure.

[0007] The buffer includes rubber teeth and rubber pillars. One end of the rubber pillar is fixedly assembled with the power supply body, and the circumferential side of the rubber pillar is integrally formed with rubber teeth.

[0008] Furthermore, each of the rubber pillars has 3 to 9 rubber teeth distributed circumferentially.

[0009] Furthermore, a rubber ring is integrally formed on the circumferential side of the rubber column and at the end near the power supply body, and the rubber ring is located between the cantilever and the power supply body.

[0010] Furthermore, the length of the rubber column extending beyond the rubber ring is at least 1.5 times the thickness of the cantilever.

[0011] Furthermore, each of the rubber posts is mounted on the power supply body via a pair of screws at its end.

[0012] Specifically, the snap-fit ​​structure includes a U-shaped spring block and a wedge block. The closed end of the U-shaped spring block is fixedly assembled with the cantilever. The open end of the U-shaped spring block and the side away from each other are fixedly installed with wedge blocks. One end of the crossbeam is provided with a receiving groove for inserting the U-shaped spring block. The receiving groove is provided with a pair of through slots for inserting the wedge blocks respectively.

[0013] Specifically, the crossbeam has three countersunk holes, which are located at the vertices of a virtual isosceles triangle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By changing the insertion angle between the docking slot and the buffer on the cantilever, the tilt angle of the cantilever can be flexibly adjusted according to the installation position requirements, making it flexible to use; while the quick installation of the cantilever on both sides through the snap-fit ​​structure can improve the convenience of assembly and make the operation simple.

[0016] The buffer has an energy-absorbing function, which can prevent vibration on the cantilever from being transmitted to the power supply body, further improving the protection capability. In addition, the installation method of suspending the power supply body can prevent the side wall of the power supply body from touching the equipment mounting surface, which can improve the heat dissipation effect of the power supply body.

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a suspended switching power supply, including a power supply body 1 and a pair of cantilever arms 3. Buffer members 2 are fixedly installed at the center of both sides of the power supply body 1. One end of each cantilever arm 3 is provided with a docking groove. The buffer member 2 on the same side is inserted into the docking groove. A crossbeam 5 is fixedly installed at the end of one cantilever arm 3 away from the docking groove. The end of the other cantilever arm 3 away from the docking groove is connected to the crossbeam 5 through a snap-fit ​​structure 4. The snap-fit ​​structure 4 allows for easy disassembly and assembly of the cantilever arm 3 and the crossbeam 5, facilitating the insertion and disassembly of the docking groove and the buffer member 2, and making assembly and use convenient.

[0024] Specifically, the buffer 2 includes rubber teeth 21 and rubber pillars 22. One end of the rubber pillar 22 is fixedly assembled with the power supply body 1. The rubber teeth 21 are integrally formed on the circumferential side of the rubber pillar 22. The buffer 2 is made of rubber material and has the function of absorbing energy. The shape of the docking groove matches the buffer 2.

[0025] Furthermore, each rubber post 22 has 3 to 9 rubber teeth 21 distributed circumferentially to ensure connection strength.

[0026] A rubber ring 23 is integrally formed on the circumferential side of the rubber column 22 and at the end near the power supply body 1. The rubber ring 23 is located between the cantilever 3 and the power supply body 1. The setting of the rubber ring 23 can prevent the cantilever 3 and the power supply body 1 from making hard contact, and it also has the function of vibration reduction and noise reduction.

[0027] The length of the rubber column 22 extending beyond the rubber ring 23 is at least 1.5 times the thickness of the cantilever 3; to ensure that the cantilever 3 will not come off along the axial direction of the rubber column 22 when vibration occurs.

[0028] In addition, each rubber post 22 is connected to the power supply body 1 by a pair of screws at its end; this ensures the fixed installation strength of the rubber post 22 and prevents it from shifting.

[0029] Specifically, the snap-fit ​​structure 4 includes a U-shaped spring block 41 and a wedge block 42. The closed end of the U-shaped spring block 41 is fixedly assembled with the cantilever 3. The open end of the U-shaped spring block 41 and the side away from each other are fixedly installed with wedge blocks 42. One end of the crossbeam 5 is provided with a receiving groove for inserting the U-shaped spring block 41. The receiving groove is provided with a pair of through slots for inserting the wedge blocks 42 respectively. The U-shaped spring block 41 makes the two wedge blocks 42 have a force that keeps them away from each other. The two wedge blocks 42 can only be inserted into the receiving groove by pressing them at the same time. The wedge blocks 42 are reset after being inserted into the through slots respectively. Similarly, when disassembling and separating, the two wedge blocks 42 must also be pressed at the same time to separate them from the through slots and re-enter the receiving groove before the U-shaped spring block 41 can be pulled out.

[0030] Specifically, the crossbeam 5 has three countersunk holes 6, which are located at the vertices of a virtual isosceles triangle. The three countersunk holes 6 located at the vertices of the virtual isosceles triangle can define an installation plane. Bolts passing through the countersunk holes 6 can stably fix the crossbeam 5 in the chassis, cabinet or other equipment.

[0031] The working principle of this embodiment:

[0032] When using, such as Figure 4 As shown, first adjust the insertion angle between the docking groove and the buffer 2 to determine the tilt direction of the cantilever 3. Press the two wedge blocks 42 to insert the U-shaped spring block 41 into the receiving groove until the wedge blocks 42 are inserted into the through grooves to complete the positioning of the two cantilever 3. Install the crossbeam 5 onto the side wall of the equipment through the bolts in the countersunk hole 6 to complete the installation of the power supply body 1.

[0033] When the equipment is running, whether it is mechanical vibration or accidental vibration, when the vibration is transmitted to the buffer 2 through the cantilever 3, it can be absorbed by the buffer 2, so as to prevent the vibration from being transmitted to the power supply body 1. In addition, the power supply body 1 has no side attached to the equipment, which can improve ventilation performance and thus improve heat dissipation.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
