Description

Technical Field

[0001] This utility model relates to the field of development board mounting platform technology, and in particular to an adaptive development board mounting platform. Background Technology

[0002] A development board is a circuit board used for embedded system development, comprising a series of hardware components such as a central processing unit, memory, input devices, output devices, data paths / buses, and external resource interfaces. Development boards are typically customized by embedded system developers according to their development needs. Currently, development boards are placed on a workbench for stability testing. During oscilloscope testing, the oscilloscope probe needs to be connected to the development board. Because the development board is not fixed in place, the probe connection process causes displacement and vibration, which can easily lead to solder joint cracking, PCB deformation, or component detachment. The risks are even higher during long-term stability testing. Therefore, an adaptive fixing stage for the development board was designed to solve these problems. Utility Model Content

[0003] In view of the shortcomings of existing development board mounting stations, the purpose of this utility model is to provide an adaptive development board mounting station, which has the advantages of positioning the development board and preventing damage to the development board.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a development board adaptive fixing platform, comprising a base, a positioning clamp, a movable clamp, a buffer assembly, a lead screw, and a handwheel. The positioning clamp is fixedly connected to one side of the top end face of the base. A linear groove is provided in the middle of the top end face of the base. The lead screw is rotatably connected within the linear groove. One end of the lead screw passes through the base and is fixedly connected to the handwheel. The movable clamp has a protruding sliding block at its bottom. The movable clamp slides along the linear groove via the bottom sliding block. The sliding block has a cylindrical cavity inside. An internal spline is provided on the inner wall of the cylindrical cavity. The buffer assembly moves axially within the cylindrical cavity via the internal spline. The lead screw engages with the movable clamp through the buffer assembly.

[0005] Preferably, the buffer assembly has a cylindrical nut, a first spring and a second spring. The outer wall of the cylindrical nut is provided with an external spline. The cylindrical nut meshes with a lead screw. The cylindrical nut is axially slidably connected in the cylindrical cavity through the external spline and the internal spline. The first spring and the second spring are respectively provided on the two end faces of the cylindrical nut. The first spring and the second spring force the cylindrical nut to be located in the middle position of the cylindrical cavity.

[0006] Preferably, the end face of the movable clamping block facing the positioning clamping block is the clamping surface, and the end face of the positioning clamping block facing the movable clamping block is the clamping surface.

[0007] More preferably, the clamping surface is a concave arc-shaped surface, and the end face of the clamping surface has an inwardly recessed and laterally extended V-shaped limiting groove, the inner wall of which is covered with rubber; the concave arc-shaped clamping surface can prevent the development board from shifting horizontally after being clamped, and the V-shaped limiting groove is used to limit the vertical displacement of the development board. After the edge of the development board is inserted into the V-shaped limiting groove, the covering rubber can prevent damage to the edge of the development board.

[0008] Preferably, the base, positioning clamp, and movable clamp are all made of non-metallic materials;

[0009] The beneficial effects of this utility model are: 1. The development board is clamped and positioned by the movable clamping block driven by the lead screw to approach the positioning clamping block. The horizontal displacement of the development board is limited by the clamping surfaces of the movable clamping block and the positioning clamping block, and the vertical displacement of the development board is limited by the V-shaped limiting groove on the end face of the clamping surface; 2. The first and second springs set on both sides of the cylindrical nut in the buffer assembly can buffer and absorb the stroke of the lead screw driving the nut to move, thereby preventing the lead screw from continuing to drive the movable clamping block to move and squeeze and damage the development board after clamping is completed; 3. By covering the inner wall of the V-shaped limiting groove with rubber, when the edge of the development board is inserted into the V-shaped limiting groove, the covering rubber can prevent the edge of the development board from being damaged.

[0017] Please see Figures 1 to 4 The embodiments of this utility model include:

[0018] An adaptive mounting platform for a development board includes a base 1, a positioning clamp 2, a movable clamp 3, a buffer assembly 4, a lead screw 5, and a handwheel 6. The positioning clamp 2 is fixedly connected to one side of the top end face of the base 1. A linear groove 11 is provided in the middle of the top end face of the base 1. The lead screw 5 is rotatably connected in the linear groove 11. One end of the lead screw 5 passes through the base 1 and is fixedly connected to the handwheel 6. The movable clamp 3 has a protruding sliding block 31 at its bottom. The movable clamp 3 slides along the linear groove 11 through the bottom sliding block 31. The sliding block 31 has a cylindrical cavity 32 inside. The inner wall of the cylindrical cavity 32 is provided with an internal spline. The buffer assembly 4 moves axially within the cylindrical cavity 32 through the internal spline. The lead screw 5 engages with the movable clamp 3 through the buffer assembly 4.

[0019] The buffer assembly 4 has a cylindrical nut 41, a first spring 42 and a second spring 43. The outer wall of the cylindrical nut 41 is provided with an external spline. The cylindrical nut 41 meshes with the lead screw 5. The cylindrical nut 41 is axially slidably connected in the cylindrical cavity 32 through the external spline and the internal spline. The first spring 42 and the second spring 43 are respectively provided on the two end faces of the cylindrical nut 41. The first spring 42 and the second spring 43 force the cylindrical nut 41 to be located in the middle position of the cylindrical cavity 32.

[0020] The end face of the movable clamping block 3 facing the positioning clamping block 2 is the clamping surface 7, and the end face of the positioning clamping block 2 facing the movable clamping block 3 is the clamping surface 7.

[0021] The clamping surface 7 is a concave arc-shaped surface, and the end face of the clamping surface 7 has an inwardly recessed and laterally extended V-shaped limiting groove 71. The inner wall of the V-shaped limiting groove 71 is covered with rubber. The concave arc-shaped surface of the clamping surface 7 can prevent the development board from being horizontally displaced after being clamped. The V-shaped limiting groove 71 is used to limit the vertical displacement of the development board. After the edge of the development board is inserted into the V-shaped limiting groove 71, the covering rubber can prevent damage to the edge of the development board.

[0022] The base 1, positioning clamp 2 and movable clamp 3 are all made of non-metallic materials;

[0023] With the above settings, its specific working principle in actual operation is as follows:

[0024] First, insert the development board horizontally into the V-shaped limiting groove 71 of the clamping surface 7 of the positioning clamp 2. Then, turn the handwheel 6 clockwise. The handwheel 6 drives the lead screw 5 to rotate and push the cylindrical nut 41 that meshes with it. Since the cylindrical nut 41 is provided with a first spring 42 and a second spring 43 on both sides to force it to be located in the middle of the cylindrical cavity 32, the lead screw 5 drives the movable clamp 3 to approach the positioning clamp 2 through the cylindrical nut 41. When the right-angle edge of the development board is inserted into the V-shaped limiting groove 71 of the clamping surface 7 of the movable clamp 3, the development board is restricted between the positioning clamp 2 and the movable clamp 3.

[0025] Since the clamping surface 7 is a concave arc surface, it can prevent the development board from shifting horizontally after being clamped, and the vertical displacement of the development board can be restricted by the V-shaped limiting groove 71. The rubber covering the inner wall of the V-shaped limiting groove 71 can prevent damage to the edge of the development board.

[0026] After clamping is completed, the movable clamping block 3 cannot continue to move towards the positioning clamping block 2. If the handwheel 6 is not stopped in time, the first spring 42 and the second spring 43 set on both sides of the cylindrical nut 41 can buffer and absorb the displacement of the nut driven by the screw 5, thereby preventing the development board from being squeezed and damaged during the fixing process.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
