[0023] Please refer to Figures 1 to 4 The embodiment of the present application discloses a circuit board device, which includes a circuit board 100, a support frame 200, a positioning member and a mounting seat 300.

[0024] The mounting seat 300 is a basic component of the circuit board device. The mounting seat 300 is used to provide a mounting base for other components of the circuit board device, wherein the circuit board 100, the support frame 200 and the positioning member are all arranged on the mounting seat 300. In addition, the mounting seat 300 is also used to form some functional spaces or structures.

[0025] The circuit board 100 is the core component of the circuit board device. The circuit board 100 is used to carry electronic components and play the function of the circuit system. The circuit board 100 has a positioning hole 110, and the positioning member passes through the positioning hole 110 and is connected to the mounting seat 300. The circuit board 100 is positioned and matched with the positioning member through the positioning hole 110. The support frame 200 has a notch 210, and the edge of the circuit board 100 is arranged in the notch 210. The support frame 200 supports the edge of the circuit board 100 through the notch 210 so that the circuit board 100 is suspended on the mounting seat 300, wherein the circuit board 100 can be fixed on the mounting seat 300 through the joint action of the support frame 200 and the positioning member.

[0026] In addition, the circuit board 100 is suspended on the mounting seat 300 so that there is a gap between the circuit board 100 and the mounting seat 300, thereby forming a convection heat dissipation space 500 between the circuit board 100 and the mounting seat 300. Electronic components can be arranged on the surface of the circuit board 100 facing the mounting seat 300. In this case, the electronic components are located in the convection heat dissipation space 500 to facilitate the heat dissipation of the electronic components. That is to say, in this structure, the convection heat dissipation space 500 can not only facilitate the flow of air to form convection to dissipate heat for the circuit board 100, but also form a accommodating space to accommodate the electronic components arranged on the board surface of the circuit board 100 facing the mounting seat 300, so that the electronic components can be arranged on the board surface of the circuit board 100 facing the mounting seat 300, thereby facilitating the utilization rate of the circuit board 100. Of course, electronic components can also be arranged on the board surface of the circuit board 100 away from the mounting seat 300.

[0027] In the embodiment of the present application, there can be one positioning hole 110, and accordingly, there can be one positioning member. Opening one positioning hole 110 on the circuit board 100 can reduce the occupation of the layout area of ​​the circuit board 100, thereby facilitating the layout of electronic components on the circuit board 100, avoiding wasting the layout area of ​​the circuit board 100, and helping to improve the utilization rate of the circuit board 100. Of course, there can also be multiple positioning holes 110, and accordingly, there can also be multiple positioning members. Multiple positioning members pass through multiple positioning holes 110 one by one and are connected to the mounting seat. The circuit board 100 is positioned and matched with multiple positioning members through multiple positioning holes 110, respectively, so as to help achieve stable positioning of the circuit board 100.

[0028] The circuit board device disclosed in the embodiment of the present application improves the structure of the circuit board device involved in the related art, and is connected to the mounting seat 300 by setting a positioning piece through the positioning hole 110 of the circuit board 100, and the circuit board 100 is positioned and matched with the positioning piece through the positioning hole 110. By setting the edge of the circuit board 100 in the notch 210 of the support frame 200, the support frame 200 can support the edge of the circuit board 100 through the notch 210, so that the circuit board 100 is suspended on the mounting seat, so that the circuit board 100 is fixed on the mounting seat 300 through the joint action of the support frame 200 and the positioning piece, thereby preventing the circuit board 100 from moving.

[0029] Of course, in this structure, when a positioning hole 110 is opened on the circuit board 100, the circuit board 100 can still be fixed on the mounting base 300 through the joint action of the support frame 200 and the positioning member, thereby avoiding the risk of opening other positioning holes 110 on the circuit board 100, which may easily damage the circuit structure in the circuit board 100 and affect the normal operation of the circuit board 100.

[0030] In a further technical solution, the edge of the circuit board 100 can be in contact with the notch 210 in a direction away from the notch 210, and the hole wall of the positioning hole 110 can be in contact with the positioning piece in the direction of the notch 210, so that the circuit board 100 can be clamped and fixed by the support frame 200 and the positioning piece. This structure is easy to implement and can fix the circuit board 100 more stably.

[0031] In an optional technical solution, the notch 210 can be provided at the first end of the support frame 200, and the second end of the support frame 200 can be connected to the mounting seat 300. The first end of the support frame 200 can be the end of the support frame 200 away from the mounting seat 300, so that the notch 210 can be as far away from the mounting seat 300 as possible, so that the circuit board 100 can be suspended higher on the mounting seat 300, so that the convection heat dissipation space 500 is larger, and thus better convection heat dissipation can be achieved. At the same time, the circuit board 100 is suspended higher on the mounting seat 300, so that larger electronic components can be arranged on the board surface of the circuit board 100 facing the mounting seat 300, thereby enriching the application scenarios of the circuit board device.

[0032] Furthermore, if Figure 3 As shown, the surface of the mounting base 300 facing the circuit board 100 may be provided with a plurality of guide grooves 310 extending along a preset direction, so that the flow of air can be guided through the guide grooves 310, which is conducive to further improving the convective heat dissipation effect. Of course, the preset direction may have a plurality of sub-preset directions, and the plurality of sub-preset directions may intersect, so that the plurality of guide grooves 310 can guide the air to flow in a plurality of different preset directions respectively, thereby enabling more efficient convective heat dissipation.

[0033] like Figures 1 to 3 As shown, in order to install the support frame 200 more stably, the second end of the support frame 200 may have a supporting flange 220, and the second end of the support frame 200 may be connected to the mounting seat 300 through the supporting flange 220. The supporting flange 220 can increase the contact area between the support frame 200 and the mounting seat 300, thereby improving the structural strength of the connection between the support frame 200 and the mounting seat 300, so that the support frame 200 can be more stably set on the mounting seat 300. At the same time, the supporting flange 220 can disperse stress and reduce fatigue or crack problems caused by local stress concentration, which is beneficial to improve the reliability of the connection between the support frame 200 and the mounting seat 300, thereby enabling the support frame 200 to more stably support the circuit board 100.

[0034] like Figures 1 to 2 As shown, in one embodiment, the support flange 220 can extend in a first direction, the distribution direction of the circuit board 100 and the mounting seat 300 can be perpendicular to the first direction, and the first direction can be perpendicular to the direction of the notch 210, so that the support flange 220 can be at least partially located between the circuit board 100 and the mounting seat 300, thereby avoiding as much as possible that the support flange 220 is entirely located outside the circuit board 100 and the mounting seat 300, which easily increases the space occupied by the circuit board device.

[0035] In an alternative technical solution, the circuit board device may further include a connecting member 400. The supporting flange 220 may be provided with a connecting hole 221. The connecting member 400 may pass through the connecting hole 221 and be detachably connected to the mounting base 300, and the connecting member 400 may press and fix the supporting flange 220 to the mounting base 300. This structure is relatively simple, easy to implement, and the connection is relatively stable. Specifically, the connecting member 400 may be a screw or a bolt, so that the connecting member 400 can be detachably connected to the mounting base 300 by means of a threaded connection and press and fix the supporting flange 220 to the mounting base 300. Of course, the supporting flange 220 may also be directly snap-connected to the mounting base 300, so as to realize the connection between the support frame 200 and the mounting base 300.

[0036] In the embodiment of the present application, the support frame 200 may further have a support body 230. The notch 210 may be provided at the first end of the support body 230. The second end of the support body 230 may be connected to the supporting flange 220. The first end of the support body 230 may be the end of the support body 230 away from the mounting base 300. Of course, the second end of the support body 230 may be the end of the support body 230 close to the mounting base 300, so that the notch 210 can be as far away from the mounting base 300 as possible, so that the circuit board 100 can be suspended higher on the mounting base 300.

[0037] Further, the support body 230 may be a telescopic structure for adjusting the size of the convective heat dissipation space 500 by telescoping the support body 230. In this structure, since the size of the convective heat dissipation space 500 can be adjusted by telescoping the support body 230, the size of the convective heat dissipation space 500 can be flexibly adjusted according to the height of the installed electronic components, so that the convective heat dissipation space 500 can accommodate electronic components of various sizes. This structure is also beneficial to adjusting the convective heat dissipation effect. It should be noted that the height direction of the electronic components may be parallel to the distribution direction of the circuit board 100 and the mounting base 300.

[0038] Optionally, the support body 230 and the supporting flange 220 may be an integral structure. This structure makes the overall structural strength of the support frame 200 relatively high, so that it can withstand greater loads and stresses, which is beneficial to improving the reliability of the support frame 200. Of course, the support body 230 and the supporting flange 220 may also be a split structure. This structure can produce the support body 230 and the supporting flange 220 separately, so that after the support body 230 and the supporting flange 220 are transported to the destination, the support body 230 and the supporting flange 220 can be connected, thus avoiding the risk that the support frame 200 is easily deformed during transportation and affecting the normal operation of the support frame 200.

[0039] In one embodiment, the support frame 200 can be a grounding member, the mounting base 300 can include a grounding area, and the circuit board 100 can be grounded to the grounding area through the support frame 200, so that the support frame 200 can serve two purposes in one, so as to make full use of the support frame 200 and avoid the need to set up other additional grounding members, which is beneficial to simplifying the structural design of the circuit board device.

[0040] In a more preferred technical solution, there can be multiple support frames 200, and the multiple support frames 200 can be arranged at intervals around the circuit board 100, and can be respectively connected to the mounting seat 300. The edges of the circuit board 100 can be respectively arranged in multiple notches 210, and the multiple support frames 200 can respectively support the edges of the circuit board 100 through the corresponding notches 210, so that the circuit board 100 can be supported more stably, and the circuit board 100 can be more stably fixed on the mounting seat 300 through the joint action of the multiple support frames 200 and the positioning members.

[0041] For example, Figures 1 to 2 As shown, the circuit board 100 can be a rectangular circuit board, the support frames 200 can be three, and the positioning hole 110 and the positioning member can be one. Among them, the three support frames 200 can be arranged around the circuit board 100 at intervals, and can be connected to the mounting seat 300 respectively, the three adjacent edges of the circuit board 100 can be arranged in the three notches 210 respectively, the three support frames 200 can support the corresponding edges of the circuit board 100 respectively through the corresponding notches 210, and the three support frames 200 can be opposite to the positioning members respectively, so that the three support frames 200 can realize stable support for the rectangular circuit board, and then the rectangular circuit board can be fixed on the mounting seat 300 more stably through the joint action of the three support frames 200 and the positioning member.

[0042] In other embodiments, when there are multiple support frames 200, the multiple support frames 200 can all be grounding members, the mounting base 300 can include multiple grounding areas, and the circuit board 100 can be grounded and connected to the multiple grounding areas one by one through the multiple support frames 200, so that the circuit board 100 can achieve multi-point grounding, thereby shortening the signal loop in the circuit board 100 as much as possible, reducing signal reflection and oscillation, and helping to improve signal clarity and integrity. In addition, when the circuit board 100 is connected to a power supply, this structure can provide a more stable reference point for the power supply and reduce voltage fluctuations, which is beneficial to improving the reliability of the circuit board 100.

The disclosed electronic device includes the circuit board device of any one of the above embodiments. In one embodiment, the housing of the electronic device may include a mounting seat 300, so that the circuit board 100 can be fixed to the housing of the electronic device.

[0044] In the examples of the present application, the electronic device may be a fire and gas system, a distribution transformer, a high-voltage motor, or other devices. The embodiments of the present application do not limit the specific types of the electronic device.
