Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit boards, in particular to a seismic-resistant printed circuit board structure for a vegetable cutter. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, are usually equipped with some advanced functions in modern vegetable cutters, such as automatic control, electric drive, intelligent sensing, etc. These functions usually need to be controlled and realized by electronic circuits. As one of the main components of electronic devices, printed circuit boards (PCBs) carry various electronic components and connect them through lines to realize various functions of electronic devices.

[0003] For example, the patent document with application number 202320019313.6 discloses a nested printed circuit board, including a first printed circuit board, a second printed circuit board, a first device and a second device. The first printed circuit board is provided with a first soldering pad and a through hole matching the first device, and the second printed circuit board is provided with a second soldering pad matching the first soldering pad. The first printed circuit board is fixedly connected to the upper side of the second printed circuit board through the matching of the first soldering pad and the second soldering pad. The first device passes through the through hole and is fixed on the upper side of the second printed circuit board, and the second device is fixed on the upper side of the first printed circuit board. The utility model sets a through hole on the first printed circuit board, so that the nested printed circuit board can make full use of the Z-direction space on the printed circuit board, making its structural space more flexible, effectively improving the device integration on the printed circuit board, reducing the occupied space of a single functional module, reducing the area of ​​the printed circuit board, and providing more space for the installation of other components.

[0004] Similarly, for printed circuit boards, a vegetable cutter will perform operations such as blade rotation and food cutting when working, which will generate vibrations. The vibrations are caused by the interaction between factors such as inertia and friction that the vegetable cutter is subjected to when working. However, continuous vibrations will cause pressure and vibrations to the electronic components on the printed circuit board, which may cause components to fall off, be damaged, or cause soldering to loosen.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-seismic printed circuit board structure for a vegetable cutter is proposed. Utility Model Content

[0006] The utility model aims to provide a vegetable cutter with a shock-resistant printed circuit board structure. When the vegetable cutter is working, it will perform operations such as blade rotation and food cutting, which will generate vibrations. The vibrations are caused by the interaction between factors such as inertial force and friction force that the vegetable cutter is subjected to when working. However, continuous vibrations will cause pressure and vibrations to the electronic components on the printed circuit board, which may cause problems such as component detachment, damage or loose welding.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seismic-resistant printed circuit board structure for a vegetable cutter, comprising a circuit board body, a buffer frame, a seismic-resistant assembly and a fixing plate, a protective frame is arranged at the edge of the outer surface of the circuit board body, the buffer frame is arranged below the circuit board body, the fixing plate is arranged on the lower end surface of the buffer frame, the seismic-resistant assembly is arranged on the lower end surface of the fixing plate, two groups of seismic-resistant assemblies are arranged, a heat dissipation port is opened at the center of the fixing plate, and threaded holes are arranged at the edges of the heat dissipation port, eight groups of threaded holes are arranged, and bolts are installed in the inner cavities of the eight groups of threaded holes.

[0008] Furthermore, the anti-seismic component includes a support frame, a mounting hole and a buffer gasket. The support frame is arranged on one side of the lower end surface of the fixed plate, and the upper end surface of the support frame away from one end of the fixed plate is provided with a mounting hole, and the mounting holes are provided in two groups. The lower end surface of the support frame is provided with a buffer gasket.

[0009] Furthermore, the outer surface of the circuit board body and the inner surface of the protective frame are engaged with each other, and the material of the protective frame is a PVC structure.

[0010] Furthermore, the lower end surface of the circuit board body and the upper end surface of the buffer frame are in contact with each other, and the buffer frame is made of a rubber structure.

[0011] Furthermore, the threaded holes and the bolts have the same hole diameter, and the threaded holes and the bolts are meshed with each other, and eight groups of the bolts are distributed in a square shape around the protective frame.

[0012] Furthermore, the support frame is L-shaped, the positions of the two groups of anti-seismic components are mirror-imaged, and the buffer gasket is made of a rubber structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects: fixing the circuit board on the fixing plate by engaging the bolts with the threaded holes can effectively prevent the circuit board from moving and loosening, thereby reducing the risk of damage to the circuit board. By using the anti-vibration component, the anti-vibration performance of the circuit board in a vibration environment can be effectively improved, and the equipment can be protected from the influence of external vibration. The specific contents are as follows:

[0014] A circuit board body, a protective frame, a buffer frame, bolts, threaded holes, a fixing plate and a heat dissipation port are provided. The edges of the circuit board body and the protective frame are surrounded by eight groups of bolts, and then meshed with the threaded holes in the fixing plate, so that the circuit board body can be firmly fixed on the equipment to prevent it from moving or loosening during vibration or movement. The design of the protective frame can separate the bolts and the circuit board body by a certain distance to avoid direct contact with the circuit board body, reduce the friction and scratches on the circuit board body when the bolts are fixed, and can effectively protect the surface of the circuit board body and circuit elements. The shape of the rubber buffer frame is consistent with the circuit board body, which better fits the edge of the circuit board body 1, provides more uniform support and buffering, avoids excessive local pressure, and reduces the problem of concentrated force on the circuit board body during the fixing process. The elasticity of the rubber material can effectively absorb the vibration energy generated by the vegetable cutter when it is working, reduce the impact of the vibration, and protect the stability of the circuit board body. In this way, it can be ensured that the circuit board body is subjected to uniform force when fixed, and deformation or damage of the circuit board body due to uneven force and vibration can be avoided.

[0015] An anti-seismic component is provided, which can effectively reduce the direct contact area between the circuit board body and the vegetable cutter equipment, thereby reducing the transmission of vibration. When the equipment is subjected to external impact or vibration, the support frame of the anti-seismic component can play a role of buffering and isolation through the buffer gasket, thereby preventing the vibration from being transmitted to the circuit board body to the greatest extent and reducing the impact of vibration on the circuit board body. The softness of the buffer gasket in the anti-seismic component can effectively absorb the vibration energy of the contact with the vegetable cutter equipment and can reduce the direct contact between the vegetable cutter equipment and the support frame, thereby reducing the impact and friction of the vegetable cutter equipment and reducing the degree of vibration transmission from the equipment to the circuit board body, thereby playing an anti-seismic role. This can reduce the impact of external vibration on the equipment and improve the stability and reliability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

A protective frame 2 is arranged at the edge of the outer surface of the circuit board body 1. The circuit board body 1 is a core component of the entire circuit system of the vegetable cutter device. Through a reasonable design of the structure and the selection of materials, it can provide circuit connection and signal transmission functions, support and connect various electronic components, and ensure the normal operation of the circuit. The material of the protective frame 2 is a PVC structure. The outer surface of the circuit board body 1 and the inner surface of the protective frame 2 are mutually engaged. The protective frame 2 provides additional protection and support. The PVC structure is used to support and prevent the circuit board body 1 from being damaged by external impact and bolts 8. The elasticity and impact resistance of the PVC structure can absorb and disperse external impact forces to protect the circuit board body 1 from damage. The buffer frame 3 is arranged below the circuit board body 1. The lower end surface of the circuit board body 1 and the upper end surface of the buffer frame 3 abut against each other. The material of the buffer frame 3 is a rubber structure. The buffer frame 3 provides buffering and shock absorption functions to reduce the impact of external vibration on the circuit board body 1. The shape of the rubber buffer frame 3 is consistent with that of the circuit board body 1, which better fits the edge of the circuit board body 1, provides more uniform support and buffering, and avoids local The pressure is too large, which reduces the problem of force concentration on the circuit board body 1 during the fixing process. The softness and elasticity of the rubber material absorb and reduce external vibration energy to protect the circuit board body 1 from vibration damage. The fixing plate 5 is arranged on the lower end surface of the buffer frame 3. A heat dissipation port 6 is opened at the center of the fixing plate 5. The circuit board body 1 increases the space in contact with the air through the heat dissipation port 6, and the edge of the heat dissipation port 6 is provided with a threaded hole 7. There are eight groups of threaded holes 7, and the inner cavities of the eight groups of threaded holes 7 are all installed with bolts 8. The threaded holes 7 and the bolts 8 have the same aperture size, and the threaded holes 7 and the bolts 8 are mutually The eight groups of bolts 8 are arranged in a square shape around the protective frame 2. Through the tightening action of the threaded holes 7 and the bolts 8, the eight groups of bolts 8 surround the edges of the circuit board body 1 and the protective frame 2, and then mesh with the threaded holes 7 in the fixing plate 5, so that the circuit board body 1 can be firmly fixed on the device to prevent it from moving or loosening during vibration or movement. The circuit board body 1 is engaged with the protective frame 2 and stacked on the upper end of the buffer frame 3, so that the elasticity of the rubber material of the buffer frame 3 can effectively absorb the vibration energy generated by the vegetable cutter when it is working, reducing the impact of the vibration.

[0023] The anti-seismic component 4 is arranged on the lower end surface of the fixing plate 5. Two groups of anti-seismic components 4 are arranged. The positions of the two groups of anti-seismic components 4 are mirror images, providing support and stable fixing functions, and can effectively resist external vibration and impact. The anti-seismic component 4 includes a support frame 401, a mounting hole 402 and a buffer gasket 403. The support frame 401 is arranged on one side of the lower end surface of the fixing plate 5. The shape of the support frame 401 is L-shaped. The support frame 401 can be firmly connected to the fixing plate through the L-shaped shape of the structural design and the solid material. 5, to withstand external forces, the upper end surface of the support frame 401 away from the fixed plate 5 is provided with a mounting hole 402, and two groups of mounting holes 402 are provided, which are fixed to the vegetable cutter equipment by installing screws and other connecting parts, and the lower end surface of the support frame 401 is provided with a buffer gasket 403, and the material of the buffer gasket 403 is a rubber structure. The buffer gasket 403 adopts a rubber structure material and is used to absorb and reduce the impact force caused by external vibration, provide buffering and shock absorption functions, and protect the stability of the fixed plate 5 and the circuit system.

[0024] In summary, if Figures 1 to 4 As shown, the vegetable cutter uses a shock-resistant printed circuit board structure. The circuit board body 1 carries and connects various electronic components on the vegetable cutter equipment to coordinate overall signal transmission and data processing. The edge of the protective frame 2 is surrounded by eight groups of bolts 8 to fix the circuit board body 1, and then engages with the threaded holes 7 in the fixing plate 5, so that the circuit board body 1 can be firmly fixed on the equipment to prevent it from moving or loosening during vibration or movement. The protective frame 2 separates the bolts 8 and the circuit board body 1 by a certain distance to avoid direct contact with the circuit board body 1 and reduce friction and scratches on the circuit board body 1 when the bolts 8 are fixed, and then abuts against the buffer frame 3 made of rubber material, the outer ring shape of which is consistent with the circuit board body 1, so as to better fit the circuit board body 1. The edge can effectively absorb the vibration energy generated by the vegetable cutter when it is working and reduce the impact of the vibration. The circuit board body 1 increases the space in contact with the air at the heat dissipation port 6 for heat dissipation. The anti-vibration component 4 reduces the contact area between the circuit board structure and the equipment, thereby reducing the transmission of vibration. When the equipment is subjected to external impact or vibration, the support frame 401 of the anti-vibration component 4 can play a buffering and isolating role through the buffer gasket 403, thereby preventing the vibration from being transmitted to the circuit board body 1 to the greatest extent and reducing the impact of the vibration on the circuit board body 1. The softness of the buffer gasket 403 can effectively absorb the vibration energy of the contact with the vegetable cutter equipment, and screws and other connectors are installed through four groups of mounting holes 402 to fix it to the vegetable cutter equipment.
