Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically a card-type circuit board for AC / DC converter charging sockets for new energy vehicles. Background Technology

[0002] Charging systems for new energy vehicles involve AC / DC conversion, which typically refers to converting alternating current (AC) supplied by the power grid into direct current (DC) that can be accepted by the electric vehicle's battery. This conversion is necessary for charging electric vehicles using home or public AC charging stations, as most electric vehicle batteries can only directly accept DC power. However, for DC fast charging stations, this conversion process is completed internally, allowing DC power to be supplied directly to the vehicle's battery.

[0003] In the application scenarios of new energy vehicle charging docks, circuit boards need to be fixedly installed. However, existing circuit boards are mostly fixed by directly installing multiple sets of threaded nails. This method of directly using threaded nails to install circuit boards is not only prone to damage to the circuit boards, but also has relatively poor protection. Therefore, we propose a snap-fit ​​circuit board for AC / DC conversion charging docks for new energy vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a card-type circuit board for AC / DC conversion charging sockets for new energy vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​circuit board for AC / DC converter charging sockets for new energy vehicles, comprising a circuit board mechanism, a heat sink fixedly mounted on the bottom of the circuit board mechanism, end fixing mechanisms for snap-fitting the two ends of the circuit board mechanism on both sides of the circuit board mechanism, a top locking mechanism for supporting the circuit board mechanism above the two sets of end fixing mechanisms, a bottom mounting frame below the two sets of end fixing mechanisms, and a positioning mechanism for positioning the top locking mechanism and the bottom mounting frame between the two sets of end fixing mechanisms.

[0006] Furthermore, the circuit board mechanism includes a circuit board substrate, a first positioning piece, and a first threaded locking groove. The first positioning piece is fixedly installed at both ends of the circuit board substrate, and the first positioning piece is provided with two sets of first threaded locking grooves.

[0007] Furthermore, the top locking mechanism includes a top mounting frame, a second threaded locking groove, a support plate, and a snap-fit ​​groove. Two sets of support plates are fixedly installed on both sides of the inner wall of the top mounting frame, and a snap-fit ​​groove for snapping the circuit board substrate is formed between the two sets of support plates. Two sets of second threaded locking grooves are provided on both the top mounting frame and the bottom mounting frame.

[0008] Furthermore, the end fixing mechanism includes an end support plate, a positioning frame, a third threaded locking groove and a fourth threaded locking groove. A positioning frame that engages with the first positioning plate is fixedly connected to one side of the end support plate. A third threaded locking groove is provided on the end support plate at the position corresponding to the first threaded locking groove, and a fourth threaded locking groove is provided on the end support plate at the position corresponding to the second threaded locking groove.

[0009] Furthermore, the positioning mechanism includes a positioning groove and a positioning piece. The bottom mounting frame and the top mounting frame are both provided with a positioning groove. One side of the end support piece is fixedly connected to a positioning piece inserted into the positioning groove.

[0010] Furthermore, one side of the support plate is provided with an arc-shaped chamfer for avoidance.

[0011] Compared with the prior art, the present invention has the following advantages: The heat sink of the present invention is installed below the circuit board mechanism. This arrangement can prevent the circuit board mechanism from accumulating too much heat and affecting the normal use of the components on it. The end fixing mechanism can limit the installation on both sides of the circuit board mechanism. The top locking mechanism can be installed on the top of the circuit board mechanism and can support and limit the circuit board mechanism, thereby preventing the circuit board mechanism from shaking during use. This support arrangement can leave space for the circuit board mechanism and the bottom mounting frame to facilitate heat dissipation. The positioning mechanism can pre-position the end fixing mechanism, the top locking mechanism and the bottom mounting frame during installation to prevent misalignment of the components during installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a snap-fit ​​circuit board for AC / DC converter charging sockets of new energy vehicles, including a circuit board mechanism 1. A heat sink 2 is fixedly installed at the bottom of the circuit board mechanism 1. End fixing mechanisms 3 are provided on both sides of the circuit board mechanism 1 to support and snap onto both ends of the circuit board mechanism 1. A top locking mechanism 4 is provided above the two sets of end fixing mechanisms 3 to support and bear the circuit board mechanism 1. A bottom mounting frame 5 is provided below the two sets of end fixing mechanisms 3. The heat sink 2 and the bottom mounting frame 5 are both made of aluminum material with good heat dissipation effect. A positioning mechanism 6 is provided between the two sets of end fixing mechanisms 3 to position the top locking mechanism 4 and the bottom mounting frame 5.

[0019] The heat sink 2 is installed below the circuit board mechanism 1. This arrangement prevents excessive heat accumulation on the circuit board mechanism 1 from affecting the normal operation of its components. The end fixing mechanism 3 can limit the installation on both sides of the circuit board mechanism 1. The top locking mechanism 4 can be installed above the circuit board mechanism 1 and can support and limit the circuit board mechanism 1, thereby preventing the circuit board mechanism 1 from shaking during use. This support arrangement can leave space for the circuit board mechanism 1 and the bottom mounting frame 5 to facilitate heat dissipation. The positioning mechanism 6 can pre-position the end fixing mechanism 3, the top locking mechanism 4 and the bottom mounting frame 5 during installation to prevent misalignment of the components during installation.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The circuit board mechanism 1 includes a circuit board substrate 7, a first positioning piece 8, and a first threaded locking groove 9. The first positioning piece 8 is fixedly installed at both ends of the circuit board substrate 7. The first positioning piece 8 has two sets of first threaded locking grooves 9. The end fixing mechanism 3 includes an end support piece 14, a positioning frame 15, a third threaded locking groove 16, and a fourth threaded locking groove 17. The positioning frame 15, which engages with the first positioning piece 8, is fixedly connected to one side of the end support piece 14. The third threaded locking groove 16 is provided on the end support piece 14 at the position corresponding to the first threaded locking groove 9. The fourth threaded locking groove 17 is provided on the end support piece 14 at the position corresponding to the second threaded locking groove 11.

[0021] The circuit board substrate 7 can be used to install and fix components, and the first positioning pieces 8 on both sides of the circuit board substrate 7 can be inserted into the positioning frame 15. After the first positioning piece 8 is inserted, the first threaded locking groove 9 and the third threaded locking groove 16 correspond to each other. In this way, it is convenient to use external locking screws to screw into the first threaded locking groove 9 to complete the installation and fixation of the first positioning piece 8 and the end support piece 14.

[0022] Please see Figures 1-4 The top locking mechanism 4 includes a top mounting frame 10, a second threaded locking groove 11, a support plate 12, and a snap-fit ​​groove 13. Two sets of support plates 12 are fixedly installed on both sides of the inner wall of the top mounting frame 10. A snap-fit ​​groove 13 for snapping the circuit board substrate 7 is formed between the two sets of support plates 12. Two sets of second threaded locking grooves 11 are provided on both the top mounting frame 10 and the bottom mounting frame 5.

[0023] During the installation of the top mounting frame 10, the snap-fit ​​groove 13 formed between the two sets of support plates 12 is aligned with the circuit board substrate 7. This allows the circuit board substrate 7 to be supported, snapped, and limited using the snap-fit ​​groove 13. Subsequently, the second threaded locking groove 11 and the fourth threaded locking groove 17 are aligned, allowing the top mounting frame 10 and the end support plate 14 to be fixedly connected using external locking screws.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The positioning mechanism 6 includes a positioning groove 18 and a positioning piece 19. The bottom mounting frame 5 and the top mounting frame 10 are both provided with a positioning groove 18. The end support piece 14 is fixedly connected to one side of a positioning piece 19 that is inserted into the positioning groove 18.

[0025] When the top mounting frame 10 moves toward the end support piece 14, the positioning piece 19 can be inserted into the positioning groove 18, thus completing the initial positioning of the top mounting frame 10 and the end support piece 14 and preventing misalignment between the second threaded locking groove 11 and the fourth threaded locking groove 17.

[0026] Please see Figure 3 The support plate 12 has an arc-shaped chamfer 20 on one side, which facilitates the insertion of the circuit board substrate 7 into the slot 13.

[0027] In use, firstly, the heat sink 2 is installed below the circuit board mechanism 1. This arrangement prevents excessive heat accumulation on the circuit board mechanism 1 from affecting the normal operation of its components. Then, the end fixing mechanism 3 limits the installation on both sides of the circuit board mechanism 1. Next, the top locking mechanism 4 is installed above the circuit board mechanism 1 and supports and limits its movement, preventing wobbling during use. This support arrangement allows space for heat dissipation between the circuit board mechanism 1 and the bottom mounting frame 5. The positioning mechanism 6 pre-positions the end fixing mechanism 3, top locking mechanism 4, and bottom mounting frame 5 during installation, preventing misalignment. The circuit board substrate 7 secures and mounts the components. The first positioning pieces 8 on both sides of the circuit board substrate 7 can be inserted into the positioning frame 15. After the first threaded locking groove 9 and the third threaded locking groove 16 are inserted, the first positioning piece 8 and the end support piece 14 can be installed and fixed by screwing an external locking screw into the first threaded locking groove 9. When the top mounting frame 10 is installed, the snap-fit ​​groove 13 formed between the two sets of support plates 12 is aligned with the circuit board substrate 7. The snap-fit ​​groove 13 can be used to support and snap-fit ​​the circuit board substrate 7. Subsequently, the second threaded locking groove 11 and the fourth threaded locking groove 17 are aligned. The top mounting frame 10 and the end support piece 14 can be fixedly connected by an external locking screw. When the top mounting frame 10 moves to the side of the end support piece 14, the positioning piece 19 can be inserted into the positioning groove 18. This completes the initial positioning of the top mounting frame 10 and the end support piece 14 and prevents the second threaded locking groove 11 and the fourth threaded locking groove 17 from being misaligned.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
