Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and more specifically, to a substrate mounting structure. Background Technology

[0002] Printed circuit boards (PCBs) are an indispensable component of electronic devices. The substrate, as the core material in PCB manufacturing, typically refers to a copper-clad laminate. In the production of single-sided or double-sided PCBs, the substrate material undergoes a series of precise processing steps, including hole machining, chemical copper plating, electrolytic copper plating, and etching, to form the required circuit patterns, thereby enabling the connection and functionality of electronic components. In specific production environments, such as salt pans, the stability and protection of the substrate are particularly important. However, existing substrate support frames used in salt pans generally fix the substrate to the support frame using simple clips. While convenient, this method suffers from low stability, and the substrate is prone to loosening. Utility Model Content

[0026] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] See also Figures 1 to 7As shown, this utility model provides a substrate mounting structure, which includes: a first mounting base 105 having a mounting cavity 1051; a first clamping assembly 2 installed in the mounting cavity 1051, the first clamping assembly 2 including a first clamping arm 21 and a second clamping arm 22 spaced apart along a first direction, at least one of the first clamping arm 21 and the second clamping arm 22 being movable along the first direction; and a second clamping assembly 3, the second clamping assembly 3 including a third clamping arm 31 and a fourth clamping arm 32, the third clamping arm 31 and the fourth clamping arm 32 being spaced apart along a second direction on the side wall of the first mounting base 105, the third clamping arm 31 and the fourth clamping arm 32 each including a fixing clamping member 305 and a first driving structure, the fixing clamping member 305 being located in the mounting cavity 1051, at least a portion of the first driving structure being located in the mounting cavity 1051, the first driving structure being drivenly connected to the fixing clamping member 305 to drive the fixing clamping member 305 to move along the second direction, the first direction and the second direction being perpendicular to each other.

[0028] In this embodiment, the first direction refers to Figure 1 The width direction of the first mounting base 105, and the second direction refers to... Figure 1 The first mounting base 105 is positioned along its length. When mounting the substrate 100, the substrate 100 can be first placed into the mounting cavity 1051, and the first clamping arm 21 and / or the second clamping arm 22 can be moved towards each other along a first direction until the substrate 100 can be clamped and fixed in the first direction. Then, the first driving structure drives the two fixing clamping members 305 to move towards each other along a second direction until the substrate 100 can be clamped and fixed in the second direction, thereby fixing the substrate 100 in the mounting cavity 1051 of the first mounting base 105. After the substrate 100 is placed into the receiving cavity 108, the first driving structure can also first drive the two fixing clamping members 305 to move towards each other along a second direction until the substrate 100 can be clamped and fixed in the second direction. Then, the first clamping arm 21 and / or the second clamping arm 22 can be moved towards each other along the first direction until the substrate 100 can be clamped and fixed in the first direction. As can be seen from the above, the substrate mounting structure of this application can clamp and fix the substrate 100 in the first direction and the second direction. Compared with the prior art, which fixes the substrate 100 to the support frame by a buckle, the substrate 100 can be fixed more stably in the mounting cavity 1051, making it less likely for the substrate 100 to shake in the mounting cavity 1051, and effectively improving the fixing effect of the substrate 100.

[0029] See also Figures 1 to 7As shown, in one embodiment of the present invention, the first driving structure includes a pulling part 306 and an elastic member 304. The pulling part 306 is slidably disposed on the side wall of the first mounting base 105 along the second direction. The elastic member 304 is sleeved on the pulling part 306 and is limited between the inner side wall of the first mounting base 105 and the fixing clamp 305.

[0030] In this embodiment, the elastic member 304 is located in the mounting cavity 1051, and the fixing clamp 305 is connected to the pulling part 306. In the initial state, the distance between the two fixing clamps 305 is less than the length of the substrate 100. Therefore, when it is necessary to install the substrate 100 in the mounting cavity 1051, the two pulling parts 306 are pulled manually or with a tool at the same time, so that they slide away from each other in the second direction. At this time, the two pulling parts 306 drive the fixing clamps 305 connected to them to move away from each other in the second direction, and the elastic member 304 is compressed. Then the substrate 100 is placed in the mounting cavity 1051, and then the pulling part 306 is released. Under the elastic recovery force of the elastic member 304, the two fixing clamps 305 move towards each other until they abut against the substrate 100, thereby achieving the clamping and fixing of the substrate 100 in the second direction. When it is necessary to remove the substrate 100 from the mounting cavity 1051, the two pulling parts 306 are pulled simultaneously by hand or with a tool, causing them to slide away from each other along the second direction. At this time, the two pulling parts 306 drive the corresponding fixed clamping members 305 to move away from each other, and the two fixed clamping members 305 disengage from the substrate 100. Then, the first clamping arm 21 and / or the second clamping arm 22 are moved along the first direction away from each other, and the substrate 100 can be removed.

[0031] In one embodiment, the elastic element 304 is a spring.

[0032] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the pulling part 306 includes a first connecting rod 303 and an end plate 301. The end plate 301 is located outside the mounting cavity 1051. One end of the first connecting rod 303 passes through the mounting cavity 1051 and is connected to the fixing clamp 305. The other end of the first connecting rod 303 is connected to the end plate 301. A first handle 302 is provided on the side of the end plate 301 away from the fixing clamp 305. An elastic member 304 is sleeved on the first connecting rod 303.

[0033] Through the above configuration, the connection between the pulling part 306 and the fixing clamp 305 can be realized. The first handle 302 is designed to facilitate the user to pull the end plate 301. When it is necessary to install the substrate 100 in the mounting cavity 1051, the two first handles 302 are pulled at the same time, causing them to slide away from each other in the second direction. At this time, the two end plates 301 drive the first connecting rods 303 connected to them to move away from each other. The two first connecting rods 303 drive the fixing clamp 305 connected to them to move away from each other. The elastic member 304 is compressed. Then the substrate 100 is placed into the mounting cavity 1051. Then the first handles 302 are released. Under the elastic restoring force of the elastic member 304, the two fixing clamps 305 move towards each other until they abut against the substrate 100, thus realizing the clamping and fixing of the substrate 100 in the second direction. When it is necessary to remove the substrate 100 from the mounting cavity 1051, pull the two first handles 302 simultaneously to slide them away from the substrate 100 along the second direction. At this time, the two end plates 301 drive the first connecting rods 303 connected to them to move away from the substrate 100. The two first connecting rods 303 drive the fixed clamping members 305 connected to them to move away from the substrate 100. The two fixed clamping members 305 disengage from the substrate 100. Then, move the first clamping arm 21 and / or the second clamping arm 22 away from each other along the first direction to remove the substrate 100.

[0034] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the substrate mounting structure further includes a lifting mechanism 4, which is drivenly connected to the first mounting base 105 to drive the first mounting base 105 to move in the vertical direction.

[0035] With the above settings, the first mounting base 105 can be raised and lowered, thereby adjusting the height of the substrate 100. This can prevent damage to the circuitry of the substrate 100 caused by rising seawater tides and improve the protective performance of the mounting structure for the substrate 100.

[0036] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the lifting mechanism 4 includes a lifting component and a driving component. The lifting component includes a support part 104 and a lifting part 413. The support part 104 has a receiving cavity 108. The lifting part 413 is slidably disposed in the receiving cavity 108. One end of the lifting part 413 near the first mounting base 105 is connected to the first mounting base 105. The driving component is drivenly connected to the lifting part 413 to drive the lifting part 413 to move vertically relative to the support part 104.

[0037] In this embodiment, one end of the lifting part 413 is slidably engaged with the support part 104, and the other end of the lifting part 413 is connected to the first mounting base 105. The driving component drives the lifting part 413 to move vertically relative to the support part 104, and the lifting part 413 drives the first mounting base 105 connected to it to move vertically, thereby realizing the adjustment of the height of the substrate 100.

[0038] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the lifting mechanism 4 further includes a second mounting base 41, and a drive assembly is mounted on the second mounting base 41. The drive assembly includes a first drive motor 402, a worm gear 404, and a worm wheel 405. The first drive motor 402 is drivenly connected to the worm gear 404. The worm gear 404 extends in a vertical direction. A second connecting rod 407 is fixedly passed through the worm wheel 405. At least one end of the second connecting rod 407 is connected to a third connecting rod 409. The end of the third connecting rod 409 away from the second connecting rod 407 forms a drive engagement with the end of the lifting part 413 away from the first mounting base 105.

[0039] In this embodiment, the first drive motor 402 drives the worm gear 404 to rotate, the rotation of the worm gear 404 drives the worm wheel 405 to rotate, the rotation of the worm wheel 405 drives the first connecting rod 303 to rotate, the rotation of the second connecting rod 407 drives the third connecting rod 409 to rotate, and the end of the third connecting rod 409 away from the second connecting rod 407 forms a driving engagement with the end of the lifting part 413 away from the first mounting base 105, thereby driving the lifting part 413 to move in the vertical direction.

[0040] See also Figures 1 to 7 As shown, in one embodiment of the present invention, a column 412 is provided at the end of the lifting part 413 away from the first mounting base 105, and a U-shaped structure 410 is provided at the end of the third connecting rod 409 away from the second connecting rod 407, and the column 412 is slidably disposed in the U-shaped structure 410.

[0041] In this embodiment, along the second direction, through slots 1041 are provided on both opposite sidewalls of the support portion 104. The through slots 1041 extend vertically, and the U-shaped structure 410 passes through the two through slots 1041 in sequence. The column 412 is slidably disposed within the U-shaped structure 410. When the third connecting rod 409 rotates, the U-shaped structure 410 rotates accordingly. During the rotation of the U-shaped structure 410, the column 412 slides vertically within the receiving cavity 108. Through the above arrangement, the lifting portion 413 can slide vertically relative to the support portion 104 as the U-shaped structure 410 rotates, thereby adjusting the height of the first mounting base 105 and thus adjusting the height of the substrate 100. This prevents the substrate 100 from being submerged in seawater due to rising tides, thereby avoiding corrosion of the substrate 100 and improving the protective performance of the substrate mounting structure for the substrate 100.

[0042] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the first clamping assembly 2 further includes a second driving structure.

[0043] In this embodiment, the second drive motor 202 drives the gear 203 to rotate. The rotation of the gear 203 causes the two toothed plates 204 meshing with it to move along the first direction, so as to drive the first clamping arm 21 and the second clamping arm 22 to move along the first direction, thereby realizing the clamping and loosening of the substrate 100.
