A mounting device for easy fixing of DC-DC modules

Abstract

This utility model discloses a convenient fixing device for DC-DC modules, relating to the field of DC-DC module technology. It includes a mounting box containing a module body. Connecting ends are mounted on both sides of the module body. Two sets of positioning components are fixedly installed in the mounting box at positions corresponding to the connecting ends. In this utility model, by controlling the pneumatic push rod within the fixing block, a protrusion moves horizontally within a square groove, causing a sponge to approach the connecting end. Multiple sponges position the connecting end, effectively protecting its safety. Furthermore, the pressure plate, when pressed, can be moved outwards, simultaneously pushing multiple supports to move. Through the pin connection of the connecting block, spring telescopic rods apply a spring force to the pressure plate in the opposite direction. The synchronous movement of multiple spring telescopic rods facilitates the confinement of the module body between the two pressure plates, thus achieving automatic and rapid fixing of the module body.

Description

Technical Field

[0001] This utility model relates to the field of DC-DC module technology, and more specifically, to a fixing device for DC-DC modules that is easy to fix. Background Technology

[0002] A DC-DC module is an electronic device used to convert the voltage of a DC power supply into different voltages to meet specific application requirements. Its main function is to convert one DC voltage value into another, achieving voltage conversion and stable output through internal switching transistors, capacitors, inductors, and other components.

[0003] Existing DC-DC modules are usually fixed by welding or mechanical means. However, in environments with high vibration, DC-DC modules are difficult to maintain a good fixation effect. Furthermore, the traditional support method is to fix the single plate with bolts. Although it is quick to install, it is difficult to achieve long-term stable fixation, thus affecting the fixation effect. Utility Model Content

[0004] The purpose of this invention is to provide a fixing device for DC-DC modules that is convenient for fixing, and can achieve the purpose of quickly and stably fixing DC-DC modules.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixing device for a conveniently fixed DC-DC module, including a mounting box, a module body installed in the mounting box, connecting ends installed on both sides of the module body, and two sets of positioning components fixedly installed in the mounting box at the positions corresponding to the connecting ends. Each positioning component consists of two parts. Each positioning component includes a fixing block with a square groove inside. A protrusion is slidably connected inside the square groove. A sponge is fixedly connected to one side of the protrusion. Two sets of limiting components are fixedly installed on both sides of the mounting box. Each set of limiting components consists of two parts. A tray is installed on both sides of the bottom of the module body. A heat dissipation component is installed on the bottom of the tray.

[0006] Furthermore, two positioning blocks are fixedly installed on the bottom of both sides of the mounting box, and positioning holes are provided on the top of the positioning blocks.

[0007] Furthermore, the outer side of the module body is provided with heat sinks, and the number of heat sinks is several.

[0008] Furthermore, a pneumatic push rod is fixedly installed on one side of the square groove, and one side of the pneumatic push rod is fixedly connected to the protrusion.

[0009] Furthermore, the limiting component includes two supports, and each of the two supports is hinged to a connecting block via a pin on the side of the support closest to the module body.

[0010] Furthermore, a spring telescopic rod is fixedly installed on one side of the connecting block one, and the two spring telescopic rods are designed to cross each other.

[0011] Furthermore, a connecting block two is fixedly installed on one side of the spring telescopic rod, and a support two is hinged to the other side of the connecting block two via a pin. A pressure plate is fixedly installed on the side of the support two near the module body.

[0012] Furthermore, the heat dissipation assembly includes a connecting rod, a support cylinder is slidably connected to the outer side of the connecting rod, and the bottom of the support cylinder is fixedly connected to the inner bottom of the mounting box.

[0013] Furthermore, a piston is fixedly installed at the bottom of the connecting rod, and a compressed air passage is provided at the bottom of the mounting box corresponding to the position of the piston.

[0014] Furthermore, a blower plate is provided at one end of the compressed air passage, and a shock-absorbing spring is installed inside the support cylinder. The two ends of the shock-absorbing spring are fixedly connected to the outer side of the connecting rod and the inner bottom surface of the mounting box, respectively.

[0015] Compared to existing technologies, the advantages of this solution are as follows: 1. This solution, by setting up sponge bodies, pressure plates, and spring telescopic rods, allows the module body to be placed on the support plate after the module body is placed on the support plate. By controlling the operation of the pneumatic push rod in the fixing block, it can drive the protrusion to move horizontally in the square groove and move the sponge body closer to the connection end. This allows multiple sponge bodies to position the connection end, effectively protecting the safety of the connection end. In addition, the pressure plate can be driven to move outward under pressure, while pushing multiple supports to move. Through the pin connection of the connecting block, the spring telescopic rod can apply elastic force to the pressure plate in the opposite direction. Through the synchronous movement of multiple spring telescopic rods, the module body is easily restricted between the two pressure plates, thereby achieving automatic and rapid fixing of the module body.

[0016] 2. This solution incorporates a heat sink, piston, compressed air passage, and blower plate. The module body can reduce its own heat through the heat sink. When the module body is placed on the tray, vibration causes the tray to be pressed and move the connecting rod away from the module body. The support cylinder restricts the connecting rod to move vertically and drives the piston, allowing the piston to slide within the compressed air passage. The damping spring cushions the movement of the connecting rod, preventing wear on the support cylinder. This allows the connecting rod to drive the piston to move stably, compressing the internal gas through the compressed air passage and cooling it down. Finally, the gas is blown onto the module body through the blower plate, thus accelerating the heat dissipation of the heat sink. Attached Figure Description

[0018] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model.

[0019] Example 1: A convenient fixing device for DC-DC modules, such as... Figure 1-4 As shown, it includes an installation box 1, a module body 4 is installed inside the installation box 1, and connection ends 5 are installed on both sides of the module body 4. Two sets of positioning components 7 are fixedly installed inside the installation box 1 at the positions corresponding to the connection ends 5. The positioning components 7 are divided into two groups. Each positioning component 7 includes a fixing block 701, a square groove 702 is provided in the fixing block 701, a protrusion 704 is slidably connected in the square groove 702, and a sponge 705 is fixedly connected to one side of the protrusion 704. Two sets of limiting components 8 are fixedly installed on both sides of the mounting box 1. Each set of limiting components 8 consists of two units. A tray 9 is installed on both sides of the bottom of the module body 4. A heat dissipation component 10 is installed at the bottom of the tray 9. In practical applications, by setting up a positioning component 7, when tidying up the wiring at the connection end 5 of the module body 4, the pneumatic push rod 703 in the fixing block 701 is controlled to move the protrusion 704. The protrusion 704 is supported and limited by the square groove 702, so that the protrusion 704 can horizontally move the sponge 705 close to the connection end 5. Then, the connection end 5 is positioned by multiple sponges 705, avoiding shaking and tangling during external operation. The sponges 705 can also effectively protect the safety of the connection end 5 during use.

[0020] Example 2: A convenient fixing device for DC-DC modules, which differs from Examples 1 and 3 in that, as shown in Example 2... Figure 2-3 As shown, two positioning blocks 2 are fixedly installed on the bottom of both sides of the mounting box 1. Positioning holes 3 are opened on the top of the positioning blocks 2. Heat sinks 6 are provided on the outer side of the module body 4. There are several heat sinks 6. A pneumatic push rod 703 is fixedly installed on one side of the square groove 702. One side of the pneumatic push rod 703 is fixedly connected to the protrusion 704. The limiting component 8 includes two supports 801. The two supports 801 are respectively hinged to the connecting blocks 802 by pins on the side of the module body 4. A spring telescopic rod 803 is fixedly installed on one side of the connecting blocks 802. The two spring telescopic rods 803 are designed to cross each other. A connecting block 804 is fixedly installed on one side of the spring telescopic rod 803. A support 805 is hinged to the other side of the connecting block 804 by pins. A pressure plate 806 is fixedly installed on the side of the support 805 near the module body 4.

[0021] In practical applications, by setting a limit component 8, when the module body 4 is placed into the mounting box 1, the pressure plate 806 can be driven to move outward under pressure, and at the same time push the multiple supports 805 to move. The horizontal movement of the supports 805 can make the connecting block 804 rotate and drive the spring telescopic rod 803 to work, so that the spring telescopic rod 803 can apply elastic force to the pressure plate 806 through the connecting block 804. Through the synchronous drive of multiple spring telescopic rods 803, the module body 4 is easily restricted between the two pressure plates 806, while avoiding damage to the module body 4 due to shaking and bumping.

[0022] Example 3: A convenient fixing device for DC-DC modules, which differs from Examples 1 and 2 in that, as shown in Example 3... Figure 4 As shown, the heat dissipation assembly 10 includes a connecting rod 1001, a support cylinder 1002 slidably connected to the outer side of the connecting rod 1001, the bottom of the support cylinder 1002 being fixedly connected to the inner bottom of the mounting box 1, a piston 1003 being fixedly installed at the bottom of the connecting rod 1001, a compression air passage 1004 being provided at the position corresponding to the piston 1003 at the inner bottom of the mounting box 1, a blower plate 1005 being provided at one end of the compression air passage 1004, and a shock-absorbing spring 1006 being installed inside the support cylinder 1002, with both ends of the shock-absorbing spring 1006 being fixedly connected to the outer side of the connecting rod 1001 and the inner bottom surface of the mounting box 1, respectively.

[0023] In practical applications, by providing a heat dissipation component 10, after the module body 4 is placed on the tray 9, when vibration occurs, the tray 9 is pressed and drives the connecting rod 1001 to move away from the module body 4. The connecting rod 1001 is connected to the piston 1003 and can slide in the compression passage 1004 through the piston 1003. Through the buffer of the shock-absorbing spring 1006, the connecting rod 1001 can drive the piston 1003 to move stably and compress the internal gas through the compression passage 1004 to become cool. Finally, the gas is blown towards the module body 4 through the blower plate 1005 to accelerate the heat dissipation of the heat sink 6.

[0024] Working principle The module body 4 is placed on the tray 9. The module body 4 can reduce its own heat through the heat sink 6. By controlling the operation of the pneumatic push rod 703 in the fixing block 701, it can drive the protrusion 704 to move horizontally in the square groove 702, and drive the sponge 705 to move closer to the connecting end 5. Thus, the multiple sponges 705 position the connecting end 5, avoiding shaking and entanglement during external operation. At the same time, the release of the module body 4 causes the pressure plates 806 on both sides to move outward, which can push the multiple supports 805 to move, and connect to the connecting block 802 via the connecting block 804. The support allows the spring telescopic rod 803 to apply elastic force to the pressure plate 806 in the opposite direction. The synchronous movement of the pressure plate 806 is restricted by the multiple spring telescopic rods 803, thus confining the module body 4 between the two pressure plates 806. In addition, when vibration occurs, the support plate 9 is pressed and drives the connecting rod 1001 to move away from the module body 4. The support cylinder 1002 can restrict the connecting rod 1001 to move vertically and drive the piston 1003 to move. This allows the piston 1003 to drive the compressed gas inside the air passage 1004 and cool it down through compression, thereby accelerating the heat dissipation of the heat sink 6.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
