Description

Technical Field

[0002] A circuit board is a printed circuit board (PCB), which is an electronic component that arranges electronic components according to the design and realizes various circuit functions through circuit connection. Circuit boards are commonly used to manufacture various electronic devices, such as computers, mobile phones, televisions, and cars. Especially in new energy vehicles, since they mainly rely on power control during use, the current passing through the circuit board is often large. In addition, the design of the control module in the circuit board is more advanced. In addition to the dedicated electronic control circuit, a dedicated battery management system is usually designed. Since the circuits of traditional new energy vehicles are all designed on a single circuit board, once a problem occurs on the circuit board, it will cause the entire electronic control system and battery management system to crash. In the prior art, application number CN202321973612.X discloses a modular circuit board for energy storage in new energy vehicles. The circuit board comprises an upper main board and a lower main board placed parallel to each other, connected by a U-shaped plate on the side. The circuit board has a smaller flat surface area, is easier to install inside the vehicle, and is convenient for partial disassembly and replacement, greatly reducing maintenance costs. The circuit board has a good cooling effect when it is hot, and has lower cooling energy consumption. Although the above technical solution uses a U-shaped plate to connect the two sets of main circuit boards, the connection between the connecting plate and the power connecting plate only conducts current through sliding contact. The vibration generated by the vehicle during driving can easily lead to poor contact between the connecting plate and the power connecting plate, thereby causing electronic control failure of the new energy vehicle. In addition, the installation space between the circuit boards is fixed, which reduces versatility. Therefore, we need to propose a combined circuit board for energy storage in new energy vehicles.

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-5 The present invention provides a technical solution: a modular circuit board for energy storage in new energy vehicles, comprising: A connecting housing 3 and mounting plates 2 are provided at both ends of the connecting housing 3. An adjustable connecting assembly 4 for adjusting the spacing between the two sets of mounting plates 2 is provided in the connecting housing 3, thereby achieving stable assembly of the circuit board body 1 and flexible spacing adjustment to meet different usage requirements; The circuit board body 1 is respectively plugged into one side of the two sets of mounting plates 2, and the locking components 5 provided on both sides of the mounting plates 2 are used to lock the circuit board body 1 to prevent it from falling off, so as to realize the positioning and assembly of the circuit board body 1; The locking assembly 5 includes a butterfly screw 51 and a block 52. A screw hole 53 for installing the butterfly screw 51 is provided on one side of the block 52. A plurality of sets of teeth 54 are provided on the other side of the block 52. The plurality of sets of teeth 54 are all arranged equidistantly in the shape of a triangular prism. The butterfly screw 51 rotates on the mounting plate 2, thereby facilitating the adjustment of the position of the block 52 so that the teeth 54 on the block 52 can be embedded in the tooth grooves on the circuit board body 1, thereby achieving efficient fixation of the circuit board body 1 and preventing the circuit board body 1 from falling off during vehicle driving.

[0016] The adjustable connection assembly 4 includes multiple groups of bearing seats 41, worms 44 and two groups of fixed seats 47. A bidirectional screw 42 is rotatably provided on the multiple groups of bearing seats 41. A worm wheel 43 meshing with the worm 44 is provided on the middle part of the outer side of the bidirectional screw 42. Both ends of the bidirectional screw 42 are threadedly connected to a movable seat 45. Support rods 46 are rotatably provided between the two groups of fixed seats 47 and the two groups of movable seats 45. The thread directions at both ends of the bidirectional screw 42 are opposite. The movable seats 45 at both ends will move toward or away from each other as the screw rotates. The movement of the movable seat 45 drives the two groups of fixed seats 47 to move through the support rod 46, thereby adjusting the spacing between the two groups of mounting plates 2. The spacing between the mounting plates 2 can be flexibly adjusted according to actual needs to adapt to the installation of circuit board bodies 1 or other related components of different sizes, thereby improving the versatility and adaptability of the modular circuit board. The worm gear 43 and worm 44 transmission are self-locking, which can accurately adjust the mounting plate 2 to the required spacing position and remain stable after the adjustment is completed. The spacing will not be easily changed by external forces, thereby improving the accuracy and reliability of the adjustment. Multiple sets of bearing seats 41 ensure the stable rotation of the bidirectional screw 42, and the support rod 46 plays a supporting and connecting role between the fixed seat 47 and the movable seat 45, so that the entire structure remains stable during the adjustment process and can withstand a certain amount of external force.

[0017] The connecting shell 3 includes an outer shell 31 and an inner shell 32. The inner shell 32 is slidably inserted into the open end of the outer shell 31. A rectangular groove 33 is provided on one side of the outer shell 31 for the end of the worm 44 to pass through. The outer shell 31 and the inner shell 32 can protect the adjustable connecting component 4, thereby improving the service life of the adjustable connecting component 4 and avoiding damage to the adjustable connecting component 4. At the same time, when adjusting the spacing of the mounting plates 2, the inner shell 32 will slide in the outer shell 31 as the mounting plates 2 move.

[0018] A circuit board mounting groove 21 for plugging in the circuit board body 1 is provided on one side of the mounting plate 2. Side grooves 23 for slidingly accommodating the block 52 are provided on both sides of the circuit board mounting groove 21. The butterfly screw 51 is rotatably arranged in the side groove 23. The side groove 23 facilitates the accommodation of the block 52 and at the same time limits the angle of the block 52 to prevent the block 52 from rotating, thereby improving the stability of the block 52 embedded in the tooth groove.

[0019] A connection terminal 25 is provided at one end of the upper surface of the mounting plate 2. A plurality of groups of power connection plates 24 electrically connected to the circuit board body 1 are provided on one side of the circuit board mounting groove 21 adjacent to the two groups of side grooves 23. A plurality of storage grooves 22 are provided at the top of the circuit board mounting groove 21. The circuit board body 1 is electrically connected to the external circuit through the connection terminals 25 and power connection plates 24 on the mounting plate 2. At the same time, the connection terminals 25 and power connection plates 24 ensure a reliable connection between the circuit board and the external circuit, ensuring the transmission of power and signals.

[0020] The assembly also includes a pre-positioning assembly 6 disposed within the plurality of receiving slots 22. The pre-positioning assembly 6 comprises a telescopic rod 61, a spring 62, and a locking bead 63. The telescopic rod 61 is fixedly connected to the top of the receiving slot 22, the spring 62 is sleeved on the outside of the telescopic rod 61, and the locking bead 63 is fixedly connected to the lower end of the telescopic rod 61 and protrudes from the receiving slot 22. When the circuit board body 1 is inserted into the circuit board mounting slot 21, the circuit board body 1 squeezes the locking bead 63, causing the telescopic rod 61 to compress the spring 62. When the circuit board body 1 reaches the correct position, the spring 62 rebounds, and the locking bead 63 engages a groove on the upper surface of the circuit board body 1, achieving pre-positioning of the circuit board body 1. This facilitates the subsequent operation of the locking assembly 5 and improves installation efficiency.

[0021] The upper surface of the circuit board body 1 is provided with grooves for embedding multiple groups of card beads 63, and both sides of the circuit board body 1 are provided with tooth grooves for embedding teeth 54. The card beads 63 embedded in the grooves can also prevent the circuit board body 1 from shaking or shifting during installation to a certain extent, thereby ensuring the accuracy of installation.

[0022] During use, first rotate the worm 44 of the adjustable connecting component 4, and drive the bidirectional screw 42 to rotate through the worm gear 43 and worm 44, so that the movable seat 45 moves along the bidirectional screw 42, and adjust the distance between the two sets of mounting plates 2 to match the size of the circuit board body 1 through the support rod 46, then insert the circuit board body 1 into the circuit board mounting groove 21 of the mounting plate 2, and the card bead 63 of the pre-positioning component 6 is embedded in the groove of the circuit board body 1 under the action of the spring 62 to achieve preliminary positioning, and then rotate the butterfly screw 51 of the locking component 5 to drive the block 52 to move, so that the teeth 54 are embedded in the tooth groove on the circuit board body 1, completing the firm fixation of the circuit board body 1, and the circuit board body 1 is electrically connected to the external circuit through the connecting terminal 25 and the power connection piece 24 on the mounting plate 2, ensuring the stable operation of the circuit board in the automobile energy storage system.

[0023] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
