Technical Field

[0001] This utility model relates to a circuit board, specifically a protective structure for a circuit board, and belongs to the field of circuit board technology. Background Technology

[0002] Circuit boards can be called printed circuit boards or printed circuit boards. FPC circuit boards are also known as flexible circuit boards. Flexible circuit boards are a type of printed circuit board made of polyimide or polyester film as the substrate. They are highly reliable and have excellent flexibility. They are characterized by high wiring density, light weight, thin thickness and good bending ability.

[0003] A protective structure for a circuit board is disclosed in Chinese Patent Application Publication CN219802807U. The protective shell helps protect the circuit board body and circuit components from damage. The shock-absorbing components can reduce the shaking of components caused by external vibration, avoid damage to components due to shaking, and improve the service life of the device. In addition, the protective structure is equipped with a heat dissipation fan, which can better dissipate heat from the circuit board body and improve the performance of the circuit board body.

[0004] In the above patented solutions, the protective shell can help protect the circuit board body and circuit components and prevent them from being damaged. However, the protective shell needs to be replaced and maintained after a long period of protection. The protective shell is installed on the base plate with multiple bolts, which makes disassembly and assembly quite cumbersome.

[0005] Therefore, a protective structure for circuit boards is proposed here. Utility Model Content

[0006] This utility model proposes a protective structure for circuit boards, which enables quick and easy removal and installation of the protective shell from the base plate, facilitating its replacement and maintenance.

[0007] This utility model is achieved through the following technical solution: a protective structure for circuit boards, including a base plate and a circuit board body disposed inside the base plate, the upper surface of the base plate is provided with a protective shell, and the base plate is provided with a disassembly assembly and a protective assembly.

[0008] The assembly includes two through slots and four mounting slots on the base plate. A bidirectional threaded rod is rotatably connected to the inner wall of the left through slot, and one end of the bidirectional threaded rod extends to the outside of the base plate. Two threaded plates are installed on the outer surface of the bidirectional threaded rod, and the two threaded plates are respectively connected to the two through slots. Two limiting rods are fixed on the side of the two threaded plates that are far apart from each other, and one end of the limiting rod extends into the mounting slot. A throttle is fixed to the end of the bidirectional threaded rod located outside the base plate.

[0009] Furthermore, the bottom surface of the protective shell is fixed with multiple mounting rods, and the mounting rods are inserted into the mounting grooves.

[0010] Furthermore, the mounting rod has a limiting hole, and the limiting rod is inserted into the limiting hole.

[0011] Furthermore, a sliding rod is fixed to the inner wall of the through groove, and the outer surface of the sliding rod is slidably connected to the inner wall of the hole on the threaded plate.

[0012] Furthermore, multiple sliding grooves are provided on the inner sides of both the protective shell and the base plate, and multiple sliders are fixed on both the left and right sides of the circuit board body, with the outer surface of the sliders slidably connected to the inner wall of the sliding groove.

[0013] Furthermore, a cooling fan is installed in the middle of the protective shell, and multiple heat dissipation holes are provided on the upper side of the protective shell.

[0014] Furthermore, the protective assembly includes a rubber pad fixed to the upper surface of the base plate and a plurality of damping rods, and the top ends of the damping rods and the rubber pad are both fixed to the bottom surface of the circuit board body.

[0015] This utility model provides a protective structure for circuit boards, which has the following beneficial effects: 1. The circuit board uses a protective structure. The protective shell helps protect the circuit board body and prevents it from being damaged. When the device is subjected to a collision that causes vibration, the circuit board body will squeeze the damping rod and rubber pad. The damping rod and rubber pad will buffer the external force and prevent the components from being damaged due to vibration. At the same time, the sliders on both sides of the circuit board body will slide in the grooves on the base plate and the protective shell, which can prevent the circuit board body from shifting when it moves, and facilitate better protection of the circuit board body.

[0016] 2. The circuit board uses a protective structure. By inserting the mounting rod on the protective shell into the mounting slot on the base plate, and then turning the handle to drive the bidirectional threaded rod to rotate, the rotation of the bidirectional threaded rod can drive the two threaded plates to move away from each other. The threaded plates can drive the limiting rod to insert into the limiting hole on the mounting rod, thereby installing the protective shell on the base plate to protect the circuit board body. Then, by turning the handle in the opposite direction, the limiting rod can be moved out of the limiting hole, releasing the limitation on the protective shell. At this time, the protective shell can be quickly and easily removed from the base plate for easy replacement and maintenance. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0020] Please see Figures 1-4 The present invention proposes the following implementation scheme: a protective structure for a circuit board, including a base plate 1 and a circuit board body 4 disposed inside the base plate 1. A protective shell 5 is provided on the upper surface of the base plate 1. The protective shell 5 can help protect the circuit board body 4 and prevent it from being damaged. The base plate 1 is provided with a disassembly assembly 2 and a protective assembly 3.

[0021] A cooling fan 6 is installed in the middle of the protective shell 5, and multiple heat dissipation holes 501 are opened on the upper side of the protective shell 5, which can dissipate heat for the circuit board body 4 and improve the performance of the circuit board body 4.

[0022] Please refer to this carefully. Figure 3 and Figure 4The disassembly and assembly component 2 includes two through slots 201 and four mounting slots 205 on the base plate 1. A bidirectional threaded rod 202 is rotatably connected to the inner wall of the left through slot 201, and one end of the bidirectional threaded rod 202 extends to the outside of the base plate 1. Two threaded plates 203 are installed on the outer surface of the bidirectional threaded rod 202, and the two threaded plates 203 are respectively connected to the two through slots 201. Two limiting rods 204 are fixed on the side of the two threaded plates 203 that are far apart from each other, and one end of the limiting rod 204 extends into the mounting slot 205. A throttle 207 is fixed to the end of the bidirectional threaded rod 202 located outside the base plate 1.

[0023] Multiple mounting rods 502 are fixed on the bottom surface of the protective shell 5, and the mounting rods 502 are inserted into the mounting groove 205.

[0024] The mounting rod 502 has a limiting hole 5021, and the limiting rod 204 is inserted into the limiting hole 5021.

[0025] A slide rod 206 is fixed to the inner wall of the through groove 201, and the outer surface of the slide rod 206 is slidably connected to the inner wall of the hole on the threaded plate 203.

[0026] By inserting the mounting rod 502 on the protective shell 5 into the mounting groove 205 on the base plate 1, and then rotating the handle 207 to drive the bidirectional threaded rod 202 to rotate, the rotation of the bidirectional threaded rod 202 can drive the two threaded plates 203 to move away from each other. The threaded plates 203 can drive the limiting rod 204 to be inserted into the limiting hole 5021 on the mounting rod 502, thereby installing the protective shell 5 on the base plate 1 to protect the circuit board body 4. Then, by rotating the handle 207 in the opposite direction, the limiting rod 204 can be moved out of the limiting hole 5021, releasing the limitation on the protective shell 5. At this time, the protective shell 5 can be quickly and easily removed from the base plate 1 for replacement and maintenance.

[0027] Please refer to this carefully. Figure 2 and Figure 3 The protective component 3 includes a rubber pad 302 fixed to the upper surface of the base plate 1 and a plurality of damping rods 301, and the top ends of the damping rods 301 and the rubber pad 302 are fixed to the bottom surface of the circuit board body 4.

[0028] Multiple grooves 7 are provided on the inner sides of the protective shell 5 and the base plate 1. Multiple sliders 401 are fixed on the left and right sides of the circuit board body 4, and the outer surface of the sliders 401 is slidably connected to the inner wall of the groove 7.

[0029] When the device encounters a collision that causes vibration, the circuit board body 4 will squeeze the damping rod 301 and the rubber pad 302. The damping rod 301 and the rubber pad 302 will buffer the external force it receives, preventing the components from being damaged due to vibration or other reasons. At the same time, the sliders 401 on both sides of the circuit board body 4 will slide in the grooves 7 on the base plate 1 and the protective shell 5, which can prevent the circuit board body 4 from shifting when it moves, and facilitate better protection of the circuit board body 4.

[0030] In use, this invention works as follows: The mounting rod 502 on the protective shell 5 is inserted into the mounting groove 205 on the base plate 1. Then, the handle 207 is rotated to rotate the bidirectional threaded rod 202. The rotation of the bidirectional threaded rod 202 causes the two threaded plates 203 to move away from each other. The threaded plates 203 then drive the limiting rod 204 to insert into the limiting hole 5021 on the mounting rod 502, thus mounting the protective shell 5 on the base plate 1 to protect the circuit board body 4. Then, by rotating the handle 207 in the opposite direction, the limiting rod 204 is moved out of the limiting hole 5021, releasing the limiting effect on the protective shell 5. At this point, the circuit board body 4 can be quickly and easily installed. The protective shell 5 is detached from the base plate 1 for easy replacement and maintenance. The protective shell 5 helps protect the circuit board body 4 from damage. When the device encounters a collision that causes vibration, the circuit board body 4 will squeeze the damping rod 301 and the rubber pad 302. The damping rod 301 and the rubber pad 302 will buffer the external force and prevent the components from being damaged due to vibration. At the same time, the sliders 401 on both sides of the circuit board body 4 will slide in the grooves 7 on the base plate 1 and the protective shell 5 to prevent the circuit board body 4 from shifting when it moves, thus better protecting the circuit board body 4.
