Description

Technical Field

[0002] Power components will continuously generate heat when working, and it is necessary to attach the power components to the heat-conducting surface of the heat dissipation structure to conduct heat. The power components are usually fixed by pressing with springs or fixing with glue. The advantage of gluing is that it reduces the number of parts. The disadvantage is that the glue requires certain storage conditions, the gluing environment is not environmentally friendly, and as time changes, the glue will age, and the bonding strength and heat dissipation performance will be compromised. With the development of electronic control power supply systems, the power density of flat fixing continues to increase, and the original method of fixing power components flat is gradually being eliminated. In order to make full use of the space in the casing, power components are installed vertically. Therefore, the latest popular power component fixing solution is to use springs to clamp the power components on the vertical heat dissipation wall or press them on the vertical surface of the three-dimensional waterway. In the related art, the structure of the power component installed vertically needs to remove the springs before the power components can be disassembled, which has the problem of inconvenient disassembly and assembly of the power components.

When an element is considered to be "set" to another element, it may be directly set on the other element or there may be a centrally arranged element at the same time. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.

[0031] The embodiment of the present application provides a power component fastening device 100 for fixing a power component 18. The power component fastening device 100 includes a base 11 and an elastic pressing member 12. The base 11 has a receiving portion 111. The elastic pressing member 12 is fixed to the receiving portion 111. The power component fastening device 100 also includes a guide column 13, a guide block 14 and an adjusting member 15. The guide column 13 is fixed in the receiving portion 111 of the base 11, and a first direction Z is defined that extends substantially along the length direction of the guide column 13. The guide block 14 is slidably mounted on the guide column 13 along the first direction Z. The adjusting member 15 is connected to the guide block 14 to drive the guide block 14 to move. The elastic pressing member 12 includes at least one pressing surface. The power component 18 is installed between any pressing surface and the inner side wall of the base 11. The guide block 14 can push any pressing surface to press the power component 18 against the wall surface of the receiving portion 111. The guide block 14 has a first position and a second position. When the guide block 14 is in the first position, the guide block 14 pushes any pressing surface to press the power component 18 against the wall of the accommodating portion 111; when the guide block 14 is in the second position, the pressing surface is away from the power component 18. In this power component fastening device 100, since the elastic pressing member 12 is stationary, the adjusting member 15 is connected to the guide block 14, and the adjusting member 15 drives the guide block 14 to be slidably mounted on the guide column 13 along the first direction Z, and the guide block 14 drives any pressing surface on the elastic pressing member 12 to move, so as to press the power component 18 against the wall of the accommodating portion 111. When the power component 18 needs to be disassembled, it is not necessary to disassemble the elastic pressing member 12. As long as the adjusting member 15 drives the guide block 14 to move in the opposite direction, the pressing effect of any pressing surface of the elastic pressing member 12 on the power component 18 can be released, thereby reducing the disassembly steps and improving the convenience of disassembly of the power component 18. At the same time, the power component 18 has enough space for disassembly, which can reduce the friction on the surface of the power component 18 when the power component 18 is disassembled, thereby improving the scratches on the surface of the power component 18 due to disassembly.

By continuously screwing the connecting portion 151 into the sliding portion 141, the stopping portion 152 stops the main board 121, and the adjusting member 15 can pull the sliding portion 141 close to the main board 121, so that the first guiding portion 142 abuts and pushes the first abutting portion 1222 to approach the first support plate 113 along the second direction U, so as to reduce the pressing space, thereby pressing the main body 181 of the power component 18 against the first support plate 113. When the power component 18 needs to be removed, the connecting portion 151 is continuously rotated out of the sliding portion 141, and the first guide portion 142 is moved away from the mainboard 121 under the elastic force of the first abutting portion 1222, so that the first abutting portion 1222 moves away from the first support plate 113 along the second direction U, and the clamping space is gradually restored, thereby facilitating the removal of the power component 18 from the power component fastening device 100.

[0049] The elastic pressing member 12 is stationary, and the adjusting member 15 is connected to the guide block 14. The adjusting member 15 drives the guide block 14 to be slidably sleeved on the guide column 13 along the first direction Z, and the guide block 14 drives the first abutting portion 1222 of the elastic pressing member 12 to move, so as to press the power component 18 against the wall surface of the accommodating portion 111. When the power component 18 needs to be removed, it is not necessary to remove the elastic pressing member 12. As long as the adjusting member 15 drives the guide block 14 to move in the opposite direction, the pressing of any pressing surface of the elastic pressing member 12 on the power component 18 can be released, thereby reducing the disassembly steps and improving the convenience of disassembly of the power component 18.

[0052] Embodiment 2

[0053] See also Figure 3 The difference between the second embodiment and the first embodiment lies in the matching relationship between the adjusting member 15 and the guide block 14.

The inclination direction of the first guide portion 142 is: gradually away from the first side plate 122 along the direction from the main board 121 to the sliding portion 141 ("\|" shape).

[0054] By continuously screwing the connecting portion 151 into the main board 121, since the connecting portion 151 is threadedly connected to the main board 121, the pushing head 153 abuts against the sliding portion 141, and the pushing head 153 can push the sliding portion 141 away from the main board 121. Since the first guide portion 142 gradually tilts away from the first side plate 122 along the direction of the main board 121 toward the sliding portion 141, the first guide portion 142 can abut and push the first abutting portion 1222 along the second direction U to approach the first support plate 113, so as to reduce the clamping space, thereby pressing the main body 181 of the power component 18 against the first support plate 113. When the power component 18 needs to be removed, the connecting portion 151 is continuously rotated out of the main board 121, and the first guide portion 142 is approached to the main board 121 under the elastic force of the first abutting portion 1222, so that the first abutting portion 1222 moves away from the first support plate 113 along the second direction U, and the clamping space is gradually restored, thereby facilitating the removal of the power component 18 from the power component fastening device 100.

[0055] Embodiment 3

[0056] See also Figure 4 The third embodiment differs from the first embodiment in the matching relationship between the adjusting member 15 and the guide block 14. Another matching relationship between the adjusting member 15 and the guide block 14 is described in detail below. Figure 4 The dotted line portion 14' indicates that the guide block 14 is in the first position. The solid line portion 14 indicates that the guide block 14 is in the second position. Optionally, the adjusting member 15 includes a connecting portion 151 and a push head 153, along the first direction Z, the connecting portion 151 is threadedly connected to the bottom plate 112, and the push head 153 is located in the accommodating portion 111 and abuts against the side of the guide block 14 facing the bottom plate 112. The guide block 14 is located between the first side plate 122 and the fixed plate 125, and the inclination direction of the first guide portion 142 is: gradually approaching the first side plate 122 along the direction from the main board 121 to the sliding portion 141 (" / |" shape).

[0057] By continuously screwing the connection part 151 into the bottom plate 112, the push head 153 abuts against the sliding part 141, and the push head 153 can push the sliding part 141 close to the main board 121. Since the first guide part 142 gradually approaches the first side plate 122 and tilts along the direction from the main board 121 to the sliding part 141, the first guide part 142 can abut and push the first abutting part 1222 to approach the first support plate 113 along the second direction U, so as to reduce the pressing space, thereby pressing the main body 181 of the power component 18 against the first support plate 113. When the power component 18 needs to be removed, the connection part 151 is continuously screwed out of the bottom plate 112, and the first guide part 142 is moved away from the main board 121 under the elastic force of the first abutting part 1222, so that the first abutting part 1222 is moved away from the first support plate 113 along the second direction U, and the pressing space is gradually restored, thereby facilitating the removal of the power component 18 from the power component fastening device 100.

[0062] Embodiment 5

[0063] See also Figure 7 The power component fastening device 100 in the fifth embodiment of the present application is different from the power component fastening device 100 in the fourth embodiment in that:

[0064] The elastic clamping member 12 also includes a third side plate 124, which is fixedly connected to one side of the main board 121 along the fourth direction W, the fourth direction W is perpendicular to the first direction Z, and the fourth direction W is at an angle β with the second direction U, 0°<β<360°, and α≠β. When α=60°, β=60°, the first side plate 122, the second side plate 123 and the third side plate 124 are enclosed into a triangular prism structure. The first side plate 122, the second side plate 123 and the third side plate 124 can adjust α and β to other angles according to the arrangement of the power components 18 on the circuit board 19. The structure in which the first side plate 122, the second side plate 123 and the third side plate 124 are enclosed into a triangular prism in the fifth embodiment is described in detail below.

[0065] The angle between the first side plate 122 and the second side plate 123 is 60 degrees, and the angle between the second side plate 123 and the third side plate 124 is 60 degrees. The guide block 14 further includes a third guide portion 144, which is disposed on one side of the sliding portion 141 along the fourth direction W and directly faces the third side plate 124. The base 11 further includes a third support plate 115 disposed along the fourth direction W, which directly faces the third side plate 124. The elastic pressing member 12 further includes a third pressing surface 1241, which is disposed on the side of the third side plate 124 facing the third support plate 115. The third guide portion 144 is disposed obliquely to drive the third pressing surface 1241 to move toward the third support plate 115.

[0066] It is worth noting that in order to facilitate the arrangement of the first side plate 122, the second side plate 123 and the third side plate 124, the fixed plate 125 of the elastic pressure piece 12 is fixedly connected to the bottom surface of the main board 121 facing the bottom plate 112, and the side of the fixed plate 125 away from the main board 121 is fixed to the bottom plate 112 through the guide block 14.

[0067] It can be understood that the elastic clamping member 12 can also include a fourth side plate, a fifth side plate, etc. The technical concept of such a clamping structure is similar to the technical concept of the fifth embodiment of the present application, and will not be elaborated here.

[0068] When the clamping structure of the present application is used, the main body 181 of the power component 18 is placed in the clamping space, and the guide block 14 is driven to move by the adjusting member 15, so that the first guide portion 142 abuts and pushes the first abutting portion 1222 along the second direction U to approach the first support plate 113, and / or the second guide portion 143 abuts and pushes the second abutting portion 1232 along the third direction V to approach the second support plate 114, and / or the third guide portion 144 abuts and pushes the third side plate 124 along the fourth direction W to approach the third support plate 115, so as to narrow the clamping space, thereby clamping the main body 181 of the power component 18 in the clamping space. When the power component 18 needs to be removed, there is no need to remove the elastic clamping piece 12. The adjusting piece 15 drives the guide block 14 to move in the opposite direction, so that the first abutting portion 1222 moves away from the first support plate 113 along the second direction U, and / or the second abutting portion 1232 moves away from the second support plate 114 along the third direction V, and / or the third side plate 124 moves away from the third support plate 115 along the fourth direction W. The clamping space is gradually restored, thereby facilitating the removal of the power component 18 from the power component fastening device 100, reducing the disassembly steps, and improving the convenience of disassembly of the power component 18.

[0069] In addition, those skilled in the art may also make other changes within the technical concept of the present application. Of course, these changes made based on the technical concept of the present application should be included in the scope disclosed in the present application.
