Description

Technical Field

[0001] This utility model relates to the technical field of circuit board protection devices, specifically to a waterproof and pressure-resistant circuit board. Background Technology

[0002] Circuit boards are circuit carriers composed of an insulating substrate, conductive lines, and electronic components soldered onto it. They are widely used in computers, communication equipment, home appliances, and other fields. Because circuit boards are exposed to environmental factors such as humidity, dust, corrosive gases, static electricity, and mechanical vibration for a long time, they need to be adequately protected to ensure that they can operate stably in complex environments.

[0003] Existing technologies often have the following problems when used:

[0004] In the operating environment of circuit boards, circuit boards and their protective devices are easily subjected to instantaneous impacts and compressions due to vibrations from other components in other electrical parts or other sudden situations. This can cause the circuit boards and their protective devices to shift or even deform due to impacts and compressions, which in turn affects the stability of the circuit board operation. Furthermore, circuit board protective devices are usually difficult to install and remove quickly, making the maintenance or replacement of circuit boards less convenient. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a waterproof and pressure-resistant circuit board, which can effectively solve the problems that the circuit board and its protective device are prone to positional displacement or even deformation due to impact and compression, affecting the stability of the circuit board operation, and that the circuit board protective device is difficult to quickly install and disassemble the circuit board, resulting in poor convenience of maintenance or replacement of the circuit board.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a waterproof and pressure-resistant circuit board, comprising:

[0008] The circuit board body and the protective housing are movably connected inside the protective housing;

[0009] A buffer pressure relief assembly includes several sliding rods fixedly connected to the bottom surface of the inner wall of the protective housing. A lifting plate is slidably connected to the outer peripheral wall of the several sliding rods. A buffer spring is fitted on the outer peripheral wall of each of the several sliding rods. The two ends of the buffer spring are fixedly connected to the lower end face of the lifting plate and the bottom surface of the inner wall of the protective housing, respectively. A stop plate is fixedly connected to the upper end face of the lifting plate.

[0010] The protective housing has a quick-release assembly that slides along its sidewall.

[0011] Furthermore, the buffer and pressure reduction assembly also includes several miniature shock absorbers fixedly installed on the bottom surface of the protective housing. The telescopic ends of the miniature shock absorbers are fixedly connected to the lower end face of the lifting plate. Several sealing rings are fixedly connected to both the upper and lower end faces of the lifting plate, and the sealing rings are respectively connected to several sliding rods in a sealed sliding connection.

[0012] Furthermore, the quick-release assembly includes an outer plug-in frame slidably connected to the side wall of the protective housing, an inner plug-in frame fixedly connected to the inner wall of the protective housing, and strip-shaped slots provided on both the outer and inner plug-in frames. The circuit board body matches the strip-shaped slots. Two concave slide rails are fixedly connected to the outer wall of the outer plug-in frame, and mounting plates are slidably connected to the inner sides of the two concave slide rails. Two mounting frames are fixedly connected to the outer wall of the protective housing, and insertion holes are provided on both mounting frames. The end of the mounting plate near the mounting frame slides into the mounting frame through the insertion holes. A disassembly and assembly drive component is rotatably connected to the outer wall of the outer plug-in frame, and the disassembly and assembly drive component is used to drive the two mounting plates to move.

[0013] Furthermore, the disassembly and assembly drive component includes a bidirectional screw rotatably connected to the outer wall of the outer insertion frame, a knob fixedly connected to the outer peripheral wall of the bidirectional screw, and two sliders threadedly connected to the bidirectional screw. The ends of the two mounting plates away from the mounting frame are respectively fixedly connected to the two sliders.

[0014] Furthermore, the protective housing has through holes on its sidewalls, and the outer plug-in frame matches the through holes.

[0015] Furthermore, several guide grooves are provided on the upper part of the side wall of the protective shell.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention incorporates a buffer and pressure-reducing component. When the protective housing is subjected to external pressure or vibration, the abutment plate first receives the force and transmits it to the lifting plate, causing the lifting plate to slide downwards along the slide bar. This causes several buffer springs to gradually compress, converting the externally applied pressure and vibration energy into elastic potential energy, thereby achieving the effects of buffering and pressure reduction. As the lifting plate moves up and down, the micro shock absorber also extends and retracts according to the force applied, further absorbing and dissipating vibration energy, enhancing the shock absorption effect, and ensuring the operational stability of the circuit board body.

[0018] In this invention, a sealing ring is provided. During the up-and-down movement of the lifting plate, the sealing ring will slide and seal with the sliding rod, which not only ensures the stability of the lifting plate during the sliding process, but also effectively prevents liquid from entering the interior of the protective shell and improves the waterproof performance of the protective shell.

[0019] This invention incorporates a quick-assembly and disassembly assembly. After the circuit board body is fully installed inside the protective housing using outer and inner insertion slots, two mounting plates are driven to move in opposite directions and insert into the insertion holes of the mounting frame, quickly securing the outer insertion frame to the protective housing. When the circuit board body needs to be disassembled, the bidirectional screw is driven in the opposite direction to rotate, causing the two mounting plates to separate from the mounting frame, thus quickly completing the disassembly and disassembly of the circuit board body. By enabling rapid installation and disassembly of the circuit board body, the ease of maintenance or replacement of the circuit board body is effectively improved. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Figures 1 to 4 A waterproof and pressure-resistant circuit board, comprising:

[0029] The circuit board body 1, the protective housing 2, and the buffer pressure reduction assembly 3 are movably connected inside the protective housing 2. The buffer pressure reduction assembly 3 includes several sliding rods 31 fixedly connected to the bottom surface of the inner wall of the protective housing 2. A lifting plate 32 is slidably connected to the outer peripheral wall of the sliding rods 31. Several guide grooves 6 are opened at the upper position of the side wall of the protective housing 2. A buffer spring 33 is fitted on the outer peripheral wall of each sliding rod 31. The two ends of the buffer spring 33 are fixedly connected to the lower end face of the lifting plate 32 and the bottom surface of the inner wall of the protective housing 2, respectively. A stop plate 34 is fixedly connected to the upper end face of the lifting plate 32. The buffer pressure reduction assembly 3 also includes several miniature shock absorbers 35 fixedly installed on the bottom surface of the inner wall of the protective housing 2. The telescopic ends of the miniature shock absorbers 35 are fixedly connected to the lower end face of the lifting plate 32. Several sealing rings 36 are fixedly connected to the upper and lower end faces of the lifting plate 32. The sealing rings 36 are respectively slidably connected to the sliding rods 31.

[0030] When the protective shell 2 is subjected to external pressure or vibration, the pressure is first transmitted to the abutment plate 34. The abutment plate 34 transmits the force to the lifting plate 32, causing the lifting plate 32 to slide down along the slide bar, which causes several buffer springs 33 to be gradually compressed. The several buffer springs 33 convert the pressure and vibration energy into elastic potential energy to achieve the effect of buffering and reducing pressure. When the lifting plate 32 moves up and down, the micro shock absorber 35 will also extend and retract according to the force to further absorb and consume vibration energy, enhance the shock absorption effect, and ensure the operational stability of the circuit board body 1.

[0031] Specifically, during the up-and-down movement of the lifting plate 32, the sealing ring 36 and the sliding rod 31 are in a sealing sliding cooperation, which not only ensures the stability of the lifting plate 32 during the sliding process, but also effectively prevents liquid from entering the interior of the protective shell 2 and improves the waterproof performance of the protective shell 2.

[0032] Specifically, several buffer springs 33 and several miniature shock absorbers 35 will hinder the movement of the lifting plate 32 and the abutment plate 34, so that the abutment plate 34 will not collide with several sliding rods 31, thus ensuring the buffering and pressure reduction effect of the abutment plate 34 on the protective shell 2.

[0033] Specifically, if there is liquid above the lifting plate 32, when the upper ends of several buffer springs 33 elastically push the lifting plate 32 to rise and reset, the liquid above the lifting plate 32 will be discharged to the outside through several guide channels 6, further improving the waterproof performance of the protective shell 2.

[0034] A quick-release assembly 4 is slidably connected to the side wall of the protective housing 2. The quick-release assembly 4 includes an outer insertion frame 41 slidably connected to the side wall of the protective housing 2. The side wall of the protective housing 2 has a through hole, and the outer insertion frame 41 matches the through hole. An inner insertion frame 42 is fixedly connected to the inner wall of the protective housing 2. Both the outer insertion frame 41 and the inner insertion frame 42 have strip-shaped slots. The circuit board body 1 matches the strip-shaped slots. Two concave slide rails 43 are fixedly connected to the outer wall of the outer insertion frame 41. Mounting plates 44 are slidably connected to the inner side of each of the two concave slide rails 43. Two mounting plates 44 are fixedly connected to the outer wall of the protective housing 2. Two mounting frames 45 are provided with insertion holes. The end of the mounting plate 44 near the mounting frame 45 slides with the mounting frame 45 through the insertion hole. The outer wall of the outer insertion frame 41 is rotatably connected to a disassembly and assembly drive component 5. The disassembly and assembly drive component 5 is used to drive the two mounting plates 44 to move. The disassembly and assembly drive component 5 includes a bidirectional screw 51 rotatably connected to the outer wall of the outer insertion frame 41. A knob 52 is fixedly connected to the outer peripheral wall of the bidirectional screw 51. Two sliders 53 are threadedly connected to the bidirectional screw 51. The ends of the two mounting plates 44 away from the mounting frame 45 are fixedly connected to the two sliders 53 respectively.

[0035] The circuit board body 1 is sequentially inserted into the strip slots in the outer insertion frame 41 and the inner insertion frame 42 to completely install the circuit board body 1 into the protective housing 2. After the circuit board body 1 is inserted and installed, the two mounting plates 44 are driven to move in opposite directions and insert into the insertion holes of the mounting frame 45 to quickly fix the outer insertion frame 41 onto the protective housing 2, thus achieving a quick and stable installation of the circuit board body 1. When it is necessary to disassemble the circuit board body 1, the two mounting plates 44 are driven to move towards each other and separate the mounting frame 45 to quickly complete the disassembly and removal of the circuit board body 1. By realizing the quick installation and removal of the circuit board body 1, the ease of use for maintenance or replacement of the circuit board body 1 can be effectively improved.

[0036] The working principle of this utility model is as follows:

[0037] In use, the circuit board body 1 is installed and fixed inside the protective housing 2, and the protective housing 2 is fixed to the electrical components such as the chassis, so that the abutment plate 34 faces the external environment and the circuit board body 1 faces the internal environment. When the protective housing 2 is subjected to external pressure or vibration, the pressure is first transmitted to the abutment plate 34. The abutment plate 34 transmits the force to the lifting plate 32, causing the lifting plate 32 to slide down along the slide bar, so that several buffer springs 33 are gradually compressed. During the compression process, the several buffer springs 33 can convert the external pressure and vibration energy into elastic potential energy to achieve the effect of buffering and decompression. When the lifting plate 32 moves up and down, the micro shock absorber 35 will also extend and retract according to the force to further absorb and consume vibration energy and enhance the shock absorption effect.

[0038] When installing and using the circuit board body 1, first insert the circuit board body 1 into the strip slot inside the outer insertion frame 41. Then, insert the outer insertion frame 41 and the circuit board body 1 into the protective housing 2, so that the circuit board body 1 is gradually inserted into the strip slot of the inner insertion frame 42 until the circuit board body 1 is fully installed. After the circuit board body 1 is inserted and installed, rotate the knob 52 to drive the bidirectional screw 51 to rotate, so that the two sliders 53 on the bidirectional screw 51 move in opposite directions, thereby driving the mounting plate 44 to insert into the insertion hole of the mounting frame 45, so as to quickly fix the outer insertion frame 41 on the protective housing 2, and realize the quick and stable installation of the circuit board body 1. When it is necessary to disassemble the circuit board body 1, drive the bidirectional screw 51 to rotate in the opposite direction, so that the two sliders 53 move towards each other and drive the mounting plate 44 to separate from the mounting frame 45, so as to quickly complete the separation and disassembly operation of the circuit board body 1. By realizing the quick installation and disassembly of the circuit board body 1, the ease of maintenance or replacement of the circuit board body 1 can be effectively improved.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
