Description

Technical Field

[0001] The present application relates to the technical field of printed circuit boards, and in particular to a dual-drive controller installation structure. Background Art

[0002] In the process of electronic product design, a heat sink is often used to dissipate heat from heat-generating power devices. By closely contacting the heat sink with the heat generating part of the power device, the heat dissipated by the power device can be promptly removed to avoid overheating and damage to the power device. In addition, in order to increase the effective contact area between the heat sink and the power device, a thermal conductive material is usually filled between the thermal conductive gap between the heat sink and the power device.

[0003] However, existing PCB boards are often used in the electronic field and are often set in various electronic devices. When the PCB board is in a long-term working state, it generates heat energy, which is easy to be damaged if the heat energy is not dissipated in time. Utility Model Content

[0004] In order to solve the above-mentioned problems existing in the existing printed circuit boards, the present application aims to provide a dual-drive controller installation structure.

[0005] This application provides the following technical solutions:

[0006] The dual-drive controller installation structure includes an aluminum shell for installing a circuit board. The inner wall of the aluminum shell is provided with at least two groups of heat dissipation protrusions for supporting the circuit board, and a thermal conductive patch is pasted on the heat dissipation protrusions.

[0007] By adopting the above technical solution: multiple heat dissipation protrusions are arranged to form a heat dissipation channel inside the aluminum shell to improve the heat dissipation efficiency, and a thermal conductive patch is also arranged between each heat dissipation protrusion and the circuit board to transfer the heat of the circuit board to the aluminum shell for rapid heat dissipation.

[0008] A slot is provided on the inner wall of one side of the aluminum shell, and a limiting protrusion is provided on the other side of the aluminum shell. A spring plate is connected to the limiting protrusion. The slot is used for inserting one end of the circuit board. The limiting protrusion abuts against the other end of the circuit board and one end of the spring plate presses down on the circuit board.

[0009] By adopting the above technical solution: the circuit board is inserted into the slot horizontally, one end of the circuit board is inserted into the slot, and the other end is supported by the heat dissipation protrusion and the limiting protrusion, and then the end of the circuit board is fixed by the spring plate, so the installation efficiency is high.

[0010] The thermal conductive patch is a thermal conductive silicone grease patch.

[0011] By adopting the above technical solution: the thermal conductive silicone grease has a good heat transfer effect and can quickly transfer the heat on the circuit board to the aluminum shell.

[0012] A slot is provided at one end of the aluminum shell, and a baffle is provided on the inner wall of the slot near the limiting protrusion. The cross-section of the spring plate is a V-shaped structure. A block is provided on the inner wall of one end of the spring plate, and the end is vertically inserted into the slot so that the baffle is interlocked with the block. The aluminum shell is also provided with a counter-resistance portion above the slot, and the counter-resistance portion is against the arch surface of the spring plate.

[0013] By adopting the above technical solution: the card slot is used to install the spring plate, and a counter-resistance portion is provided above the card slot. By inserting one end of the spring plate into the card slot and then pressing its arched part against the counter-resistance portion, the other end of the spring plate tends to fall down. When this end of the spring plate presses down the circuit board, the spring plate is just balanced in force to fix one end of the circuit board in the aluminum shell.

[0014] The counter-resistance portion is a limit bar arranged at the top of the side of the slot away from the baffle bar, and a notch is provided obliquely below the limit bar, and the notch is used to resist the arch surface of the spring plate.

[0015] By adopting the above technical solution: the limit bar is used to resist the arch surface of the spring plate to provide a reaction force for fixing the circuit board, and the limit bar is also provided with a groove to increase the contact area between the limit bar and the arch surface of the spring plate, thereby further improving the stability of the spring plate after installation.

[0016] The above solution has the following advantages:

[0017] 1. In the present application, a plurality of heat dissipation protrusions are provided to form a heat dissipation channel inside the aluminum shell to improve the heat dissipation efficiency, and a thermal conductive patch is also provided between each heat dissipation protrusion and the circuit board to transfer the heat of the circuit board to the aluminum shell for rapid heat dissipation.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention provides Figure 1 and 2 A dual-drive controller installation structure shown includes an aluminum shell 1 for installing a circuit board 4, and at least two groups of heat dissipation protrusions 12 for supporting the circuit board 4 are provided on the inner wall of the aluminum shell 1. A thermal conductive patch 2 is pasted on the heat dissipation protrusion 12, and the thermal conductive patch 2 is a thermal conductive silicone grease patch. Since the thermal conductive silicone grease patch has a good heat transfer effect, it can quickly transfer the heat on the circuit board 4 to the aluminum shell 1.

[0024] The aluminum shell 1 is a concave structure with a plurality of heat dissipation protrusions 12 arranged inside to form a heat dissipation channel inside the aluminum shell 1 to improve the heat dissipation efficiency, and a thermal conductive patch 2 is also arranged between each heat dissipation protrusion 12 and the circuit board 4 to transfer the heat of the circuit board 4 to the aluminum shell 1 for rapid heat dissipation.

[0025] A slot 11 is provided on the inner wall of one side of the aluminum shell 1, and a limiting protrusion 13 is provided on the other side of the aluminum shell 1. A spring plate 3 is connected to the limiting protrusion 13. The slot 11 is used to insert one end of the circuit board 4. The limiting protrusion 13 abuts against the other end of the circuit board 4, and one end of the spring plate 3 presses down on the circuit board 4. During installation, the circuit board 4 needs to be inserted horizontally from one side of the aluminum shell 1, that is, one end of the circuit board 4 is inserted horizontally into the slot 11, and the other end is supported by the heat dissipation protrusion 12 and the limiting protrusion 13. The spring plate 3 needs to be slightly opened and the end of the circuit board 4 is fixed by the spring plate 3, and the installation efficiency is high.

[0026] A slot 14 is provided at one end of the aluminum shell 1, and a baffle 141 is provided on the inner wall of the slot 14 near the limiting protrusion 13. The cross-section of the spring plate 3 is a V-shaped structure. A block 31 is provided on the inner wall of one end of the spring plate 3, and the end is vertically inserted into the slot 14 so that the baffle 141 is interlocked with the block 31. The aluminum shell 1 is also provided with a counter-resistance portion above the slot 14, and the counter-resistance portion is against the arch surface of the spring plate 3. The slot 14 is used to install the spring plate 3, and a counter-resistance portion is provided above the slot 14. By inserting one end of the spring plate 3 into the slot 14 and then pressing its arched part against the counter-resistance portion, the other end of the spring plate 3 tends to fall. When this end of the spring plate 3 presses down the circuit board 4, the spring plate 3 is just balanced in force to fix one end of the circuit board 4 in the aluminum shell 1.

[0027] The counter-resistance portion is a limiting strip 142 disposed at the top of the side of the card slot 14 away from the blocking strip 141. A notch 1421 is provided obliquely below the limiting strip 142. The notch 1421 is used to resist the arch surface of the spring plate 3. The limiting strip 142 is used to resist the arch surface of the spring plate 3 to provide a counter force for fixing the circuit board 4. Furthermore, the limiting strip 142 is further provided with a notch 1421 to increase the contact area between the limiting strip 142 and the arch surface of the spring plate 3, thereby further improving the stability of the spring plate 3 after installation.

[0028] The size of the V-shaped opening of the spring plate 3 can change with the thickness of the circuit board 4. The thicker the circuit board 4 is, the larger the angle of the V-shaped opening of the spring plate 3 is, and vice versa. This allows the device to adapt to the installation of circuit boards 4 of different thicknesses, thereby improving the installation effect.

[0029] Specifically, in another installation process, it is necessary to first insert one end of the circuit board 4 into the slot 11 to fix the circuit board 4 on that side, and then place the other end of the circuit board 4 between the limiting protrusion 13 and the heat dissipation protrusion 12, and vertically insert the spring plate 3 into the card slot 14. Since the spring plate 3 has a V-shaped opening, until a "click" sound is heard, the block 31 on the spring plate 3 is engaged with the limiting strip 142, and at this time, the arched part of the spring plate 3 is just stuck in the missing groove 1421, so that the spring plate 3 is just balanced and fixes one end of the circuit board 4. This installation method is efficient and reliable. The above describes the utility model in conjunction with specific embodiments, but those skilled in the art should be aware that these descriptions are exemplary and are not limitations on the scope of protection of the utility model, and those skilled in the art can make various variations and modifications to the utility model based on the spirit and principle of the utility model, and these variations and modifications are also within the scope of the utility model.
