As shown in fig. 1-3, the present invention provides a circuit board locking mechanism for an electronic box of a heavy vehicle, which mainly comprises: the first reinforcing frame 110, the second reinforcing frame 120, the heat sink 130, the locking bar 140, the locking bar 150, and the extractor 160.
The first reinforcing frame 110 is a rectangular sheet-shaped frame and is fixedly disposed on one side (front side) of the circuit board 100; the second reinforcing frame 120 is fixedly disposed at the other side (rear side) of the circuit board corresponding to the first reinforcing frame 110; wherein the first and second reinforcement frames 110 and 120 are fixedly coupled to the edge portions of the circuit board 100 by screws, respectively. The heat sink 130 is disposed in parallel with the second fixing frame 120 and fixedly mounted on the second reinforcing frame 110; the heat sink 130 is provided with a plurality of fins arranged in parallel to ensure uniform heat dissipation. Wherein the heat sink 130 is fixedly connected with the edge portion of the second fixing frame 120 by screws.
The lower side of the circuit board 100 is provided with a data transmission port 100a, and the second reinforcing frames 120 located at the left and right sides of the data transmission port 100a are respectively and fixedly mounted with a locking bar 140 and a locking bar 150, that is, the locking bar 140 and the locking bar 150 are respectively located at the left and right sides of the heat sink 130. The locking strips 140 and 150 may be fixedly connected to the second reinforcement frame 120 by welding, bonding, or screwing. The locking bars 140 and 150 are symmetrically disposed and parallel to the frame of the circuit board 100.
The locking bar 140 and the locking bar 150 have the same structure, and therefore, the structure of the locking bar is described by taking the locking bar 140 as an example. As shown in fig. 4-7, the locking bar 140 includes: a guide rail 141, which is a rectangular main body, and a central through hole 141a is formed in the guide rail 141 along the length direction thereof; a plurality of wedge-shaped guide grooves 142 are formed in the guide rail 141, the wedge-shaped guide grooves 142 are formed in one side of the guide rail 141 (on the same side as the heat sink 130) in the thickness direction of the circuit board 100, and the wedge-shaped guide grooves 142 are arranged in the length direction of the guide rail 141; a threaded rod 143 inserted into the central through hole 141a and penetrating the guide rail 141; a plurality of wedge-shaped sliding blocks 144, which are matched with the wedge-shaped guide grooves 142 one by one; a threaded hole 144a is formed in the wedge-shaped sliding block 144 along the length direction, and the wedge-shaped sliding block is mounted on the threaded rod 143 through the threaded hole 142a in a matching manner; the limiting groove 145 is formed at one side of the guide rail 141, and one end of the limiting groove close to the guide rail 141 is formed; and a nut 146 which is fittingly mounted on one end of the threaded rod 143 and fittingly engaged in the stopper groove 145. When the threaded rod 141 rotates, because the position of the wedge-shaped sliding block 144 is limited by the wedge-shaped guide groove 142, the inclined surface 144b of the wedge-shaped sliding block 144 is matched with the inclined surface 142a on the wedge-shaped guide groove 142, so that the inclined surface 142a along which the wedge-shaped sliding block 144 slides to the top of the guide rail 141, the wedge-shaped sliding block 144 protrudes out of the guide rail 141, which is equivalent to increasing the thickness of the locking strip 140, and the locking strip 140 is clamped in a circuit board clamping groove of the electronic box.
In this embodiment, a cylindrical head 143a is fixedly connected to the upper end of the threaded rod 143, and the end of the cylindrical head 143a has a groove matched with a screwdriver, so that the threaded rod can be turned by using the screwdriver. A nut 146 is mounted on the threaded rod at an end remote from the cylindrical head 143 a. In addition, the circuit board locking mechanism for the electronic box of the heavy vehicle further includes two extractors 160, and the extractors 160 are installed on one side of the second reinforcing frame 120 away from the data transmission port 100a of the circuit board; and the two extractors 160 are disposed adjacent to the cylindrical heads of the two threaded rods, respectively. One end of the extractor 160 is rotatably connected to the second reinforcing frame 120 through a rotating shaft 160a, and when the circuit board 100 needs to be taken out of the electronic box, the extractor 160 is turned to a position parallel to the threaded rod, so that the circuit board 100 can be pulled out through the extractor 160. When the circuit board 100a is installed in the electronic box, the extractor 160 can be flipped to a position parallel to the upper edge of the circuit board 100 (perpendicular to the threaded rod) to avoid taking up too much space.
In another embodiment, the first reinforcing frame 110 and the second reinforcing frame 120 are made of insulating materials.
In another embodiment, each locking strip is provided with two wedge-shaped sliding blocks which are respectively arranged close to two ends of the threaded rod.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
