Description

Technical Field

[0001] This utility model relates to the field of PCB fixing technology, and in particular to a PCB embedded device support and fixing structure. Background Technology

[0002] Embedded components in PCBs are resistors, capacitors, and chip electronic devices that are directly embedded inside the PCB, replacing the traditional surface mount method. This technology greatly shortens the signal transmission path, reduces electromagnetic interference, improves signal integrity, and effectively reduces the space occupied by the PCB, thereby improving the integration and reliability of electronic devices.

[0003] To ensure the stability of embedded PCB components during production, transportation, and use, a specialized support and fixing structure is required. This structure positions and clamps the PCB board to prevent displacement, deformation, or damage to the components due to external forces, thus ensuring the performance and lifespan of the electronic equipment. It must not only meet the installation requirements of PCB boards of different specifications and embedded components, but also have good heat dissipation performance to dissipate the heat generated by the components in a timely manner and avoid affecting the normal operation of the components due to excessive temperature.

[0004] Traditional support and fixing structures have a single heat dissipation function, relying solely on the PCB board itself for heat dissipation. This cannot quickly dissipate the heat generated by embedded components, causing the components to operate in high-temperature environments for extended periods, accelerating aging and shortening their lifespan. Installing high thermal conductivity metal heat sinks on the surface of the support and fixing structure or at the contact points with the PCB board increases the heat dissipation area, accelerates the diffusion of heat to the surrounding environment, and improves heat dissipation efficiency. However, existing fixing devices mostly use fixed structures, which cannot be adapted to PCB boards of different lengths, resulting in poor applicability. Frequent replacement of devices or adjustment of layout is required for different sizes, which is cumbersome and costly. Utility Model Content

[0007] The fixing mechanism includes two fixing bars, with adjacent sides of the two fixing bars fixedly connected to the front and rear sides of the base, respectively. Each fixing bar has a groove at its top, and sliders are slidably connected to the bottom left and right ends of the inner sides of the grooves.

Multiple clamping plates are fixedly connected to adjacent sides of each of the two positioning plates. A slot is provided at the right end of the left clamping plate and the left end of the right clamping plate. A support assembly is provided at the inner bottom of the base.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes multiple top plates, the outer sides of which are slidably connected to the inner bottom of the mounting block, and a reset spring is fixedly connected to the top of each of the multiple top plates.

[0012] As a further description of the above technical solution:

[0013] The support assembly includes two hollow columns, the bottoms of which are fixedly connected to the top left and right sides of the base, respectively. Support springs are fixedly connected to the bottom of the interior of each of the two hollow columns, and cushioning pads are fixedly connected to the top of each of the two support springs.

[0014] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The outer middle portions of the two lead screws pass through the inner left and right sides of the base and are fixedly connected to the corresponding positioning plates. The outer bottoms of the two buffer pads are slidably connected to the inner tops of the two hollow columns.

[0022] This utility model has the following beneficial effects:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a PCB embedded device support and fixing structure, including a base 1, a fixing mechanism 2 is provided on the front and rear sides of the base 1, the fixing mechanism 2 is used to fix PCB boards of different specifications to enhance the applicability of the structure, and a positioning mechanism 3 is provided on the left and right sides of the base 1 to provide positioning for the PCB board and ensure the accuracy of the installation position.

[0035] The fixing mechanism 2 includes two fixing bars 201. The adjacent sides of the two fixing bars 201 are fixedly connected to the front and rear sides of the base 1, respectively, providing basic installation support for the fixing mechanism 2 and ensuring structural stability. Each fixing bar 201 has a groove 202 at its top, providing guiding space for the sliding of the slider 203, making the slider 203 move more stably. Sliding sliders 203 are slidably connected to the left and right ends of the inner bottom of the two grooves 202, allowing for position adjustment to accommodate the fixing requirements of PCB boards of different sizes. Threaded cylinders 204 are fixedly connected to the adjacent sides of the two front sliders 203 and the two rear sliders 203 for adjustment. The screw 205 is used to adjust the position of the mounting block 206. The inner rear ends of the two front threaded cylinders 204 and the inner front ends of the two rear threaded cylinders 204 are threaded with adjusting screws 205. Rotating the adjusting screws 205 can push the mounting block 206 to move, thereby fixing the PCB board. The adjacent sides of the two front adjusting screws 205 and the two rear adjusting screws 205 are rotatably connected to the mounting block 206, which is used to install the positioning pin 207 and the reset assembly 208. The interior of the multiple mounting blocks 206 is slidably connected with the positioning pin 207, which can be inserted into the positioning hole of the PCB board and fix the PCB board.

[0036] Each of the multiple mounting blocks 206 has a reset component 208 inside, which can automatically reset after the positioning pin 207 is pulled out. The reset component 208 includes multiple top plates 2081. The outer sides of the multiple top plates 2081 are slidably connected to the inner bottom of the mounting block 206, providing a support base for the reset spring 2082 and ensuring the stable installation of the reset component 208. The top of each of the multiple top plates 2081 is fixedly connected to the reset spring 2082. By pulling the positioning pin 207 upward, the locking of the PCB board is released, the positioning pin 207 is released, the reset spring 2082 rebounds, and the positioning pin 207 is reset.

[0037] Specifically, when using the fixing mechanism 2, firstly, according to the size of the PCB board, the slider 203 in the sliding groove 202 is adjusted to match the length of the PCB board. Since a threaded cylinder 204 is fixedly connected to the adjacent side of the slider 203, the threaded cylinder 204 also moves to the corresponding position. Next, the adjusting screw 205 is rotated. Because the adjusting screw 205 is threadedly connected to the threaded cylinder 204, rotating the adjusting screw 205 can push the mounting block 206, which is rotatably connected to its adjacent side, towards the PCB board. The mounting block 206 is moved closer to the PCB board. When the mounting block 206 is close to the PCB board, the positioning pin 207 is inserted into the positioning hole of the PCB board to complete the initial positioning of the PCB board. If it is necessary to release the fixation, the positioning pin 207 is pulled upward. At this time, the positioning pin 207 drives the top plate 2081 fixedly connected to it to move upward, compressing the return spring 2082, thereby releasing the lock on the PCB board. After the positioning pin 207 is released, the return spring 2082 rebounds, pushing the top plate 2081 and the positioning pin 207 to reset, so as to prepare for the next fixing operation.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The positioning mechanism 3 includes two positioning plates 301. The bottoms of the two positioning plates 301 are slidably connected to the left and right ends of the bottom inner side of the base 1, respectively. The position can be adjusted by sliding laterally along the base 1 to achieve positioning adaptation for PCB boards of different sizes. The two positioning plates 301 are rotatably connected to lead screws 302 on opposite sides. The rotation of the lead screws 302 converts the rotational motion into linear motion, driving the positioning plates 301 to move left and right. The two lead screws 302 are fixedly connected to knobs 303 on opposite sides, which facilitates manual rotation of the lead screws 302 by the operator, improving the ease of operation. Multiple clamping plates 304 are fixedly connected to adjacent sides of the two positioning plates 301 for clamping the PCB board from both sides. The right end of the left clamping plate 304 and the left end of the right clamping plate 304 are provided with slots 305, which can engage with the edge of the PCB board to further improve the clamping stability.

[0039] A support component 306 is provided on the inner bottom of the base 1 to provide support for the bottom of the PCB board and prevent it from being suspended and deformed by force. The support component 306 includes two hollow columns 3061. The bottom of the two hollow columns 3061 is fixedly connected to the top left and right sides of the base 1, respectively, to provide a mounting carrier for the support spring 3062 and the buffer pad 3063, ensuring the structural strength of the support component 306. The bottom of the two hollow columns 3061 is fixedly connected to the support spring 3062. The elastic deformation of the spring provides buffer support for the PCB board and reduces the impact of external forces on the PCB board. The top of the two support springs 3062 is fixedly connected to the buffer pad 3063, which can directly contact the PCB board to prevent the support spring 3062 from damaging the surface of the PCB board and enhance the buffer and shock absorption effect.

[0040] Specifically, when using the positioning mechanism 3, the PCB board is first placed on the base 1. The operator manually rotates the knob 303 on the side furthest from the lead screw 302, according to the width of the PCB board. The knob 303 drives the lead screw 302 to rotate. Since the lead screw 302 is rotatably connected to the positioning plate 301 and its outer center penetrates the base 1, the rotational motion of the lead screw 302 is converted into linear motion, driving the two positioning plates 301 to slide laterally on the left and right sides of the bottom inner side of the base 1, adjusting the position of the positioning plates 301. When the positioning plate 301 moves to the appropriate position, multiple clamping plates 304 fixedly connected to its adjacent side clamp the PCB board from both sides. The PCB board is held in place while the slots 305 at the right end of the left clamping plate 304 and the left end of the right clamping plate 304 engage with the edge of the PCB board, further securing the PCB board. During the clamping process, the support component 306 at the bottom inner side of the base 1 plays a role. The bottom of the PCB board contacts the buffer pad 3063, and the buffer pad 3063 compresses the support spring 3062 at the bottom inside the hollow column 3061 under force. The support spring 3062 generates buffer support force through elastic deformation, preventing the PCB board from being suspended and deformed by force. At the same time, the buffer pad 3063 prevents the support spring 3062 from damaging the surface of the PCB board, thus achieving the positioning, clamping and support of the PCB board.

[0041] Reference Figure 2 and Figure 6Mounting plates 4 are fixedly connected to the left front and rear ends and the right front and rear ends of the base 1, providing an installation interface for the entire support and fixing structure, making it easy to install it securely on other equipment or workbenches. Mounting holes 5 are opened on the top of multiple mounting plates 4, and mounting plates 4 can be fixed to external structures by passing bolts through the mounting holes 5. Multiple support columns 6 are fixedly connected to the bottom inner side of the base 1, providing a support base for the heat dissipation pad 7, ensuring that the heat dissipation pad 7 can fit against the bottom of the PCB board. The top of multiple support columns 6 is fixedly connected to the same heat dissipation pad 7, which can make close contact with the bottom of the PCB board and conduct heat generated by the PCB board. Multiple heat dissipation holes 8 are opened on the bottom inner side of the base 1, which can allow air to circulate inside the base 1 and accelerate heat dissipation.

[0042] Multiple top plates 2081 are fixedly connected to the outer middle of the corresponding positioning pins 207 to ensure that the top plates 2081 can move synchronously with the positioning pins 207. Multiple return springs 2082 are slidably connected to the outer middle of the corresponding positioning pins 207. When the positioning pins 207 are pulled upward, the return springs 2082 are compressed. After the external force disappears, the return springs 2082 push the positioning pins 207 to reset. The outer middle of the two lead screws 302 pass through the inner left and right sides of the base 1 and are fixedly connected to the corresponding positioning plates 301, so that when the lead screws 302 rotate, they can drive the positioning plates 301 to move smoothly. The outer bottom of the two buffer pads 3063 are slidably connected to the inner top of the two hollow columns 3061 to ensure that the buffer pads 3063 can slide smoothly inside the hollow columns 3061 when subjected to force.

[0043] Specifically, when installing base 1, the structure is first fixed to the equipment or workbench using mounting plate 4. Bolts are then inserted through the mounting holes 5 on the top of mounting plate 4 to achieve a stable connection with the external structure. After installation, the PCB board is placed on base 1. The support column 6 on the inner bottom of base 1 supports the heat dissipation pad 7, ensuring the pad 7 fits against the bottom of the PCB board. When the PCB board generates heat during operation, the heat is conducted to the inner side of base 1 through the heat dissipation pad 7. Simultaneously, the ventilation holes 8 promote airflow and accelerate heat dissipation. When using fixing mechanism 2 and positioning mechanism 3... After the positioning pin 207 is inserted into the positioning hole of the PCB board, if it needs to be pulled out, pull the positioning pin 207 upward. The positioning pin 207 drives the top plate 2081 to move upward and compress the reset spring 2082. After releasing, the reset spring 2082 pushes the positioning pin 207 to reset. When adjusting the positioning plate 301, turn the knob 303 to drive the lead screw 302 to rotate. The lead screw 302 drives the positioning plate 301 to slide on the bottom of the inner side of the base 1. At this time, the buffer pad 3063 slides up and down in the hollow column 3061 with the pressure of the PCB board. The buffer support is achieved by the elastic deformation of the support spring 3062.

[0044] Working principle: When using the fixing mechanism 2, first place the PCB board on the base 1. According to the size of the PCB board, slide the slider 203 located in the top groove 202 of the two fixing bars 201 to adjust the position of the slider 203 in the groove 202 to match the length of the PCB board. Since the adjacent side of the slider 203 is fixedly connected to the threaded cylinder 204, the threaded cylinder 204 will also move to the corresponding position. Then, rotate the adjusting screw 205. Since the adjusting screw 205 is threadedly connected to the threaded cylinder 204, rotating the adjusting screw 205 can push the rotatably connected adjacent... The mounting block 206 on one side moves towards the PCB board, gradually bringing the mounting block 206 closer to the PCB board. When the mounting block 206 is close to the PCB board, the positioning pin 207 is inserted into the positioning hole of the PCB board to complete the initial positioning of the PCB board. If it is necessary to release the fixation, pull the positioning pin 207 upward. At this time, the positioning pin 207 drives the top plate 2081 fixedly connected to it to move upward, compressing the reset spring 2082, thereby releasing the lock on the PCB board. After the positioning pin 207 is released, the reset spring 2082 rebounds, pushing the top plate 2081 and the positioning pin 207 to reset.

[0045] Furthermore, when using the positioning mechanism 3, firstly, according to the length of the PCB board, manually rotate the knob 303. The knob 303 drives the lead screw 302 to rotate. Since the lead screw 302 is fixedly connected to the positioning plate 301 and its outer center passes through the base 1, the rotational motion of the lead screw 302 is converted into linear motion, driving the two positioning plates 301 to slide left and right on the bottom inner side of the base 1. Adjust the position of the positioning plates 301 to match the size of the PCB board. Then, after the positioning plates 301 move into place, the clamping plate 304 clamps the PCB board from both sides. At the same time, the slot 305 engages with the edge of the PCB board to improve clamping stability. During the clamping process, the bottom of the PCB board is pressed on the buffer pad 3063. The buffer pad 3063 is compressed downward by the force to the support spring 3062. The support spring 3062 provides buffer support force through elastic deformation to prevent the PCB board from being suspended and deformed. At the same time, the buffer pad 3063 prevents the support spring 3062 from damaging the surface of the PCB board, thus realizing the positioning, clamping and buffer support of the PCB board.
