Description
Technical Field
[0001] This invention relates to the field of circuit board technology, specifically to a combined circuit board for energy storage in new energy vehicles. Background Technology
[0002] A circuit board (PCB) is a type of printed circuit board that arranges electronic components according to a design and connects them through circuits to realize various circuit functions. PCBs are commonly used to manufacture various electronic devices, such as computers, mobile phones, televisions, and automobiles. Especially in new energy vehicles, since they mainly rely on power control during use, the current flowing through the circuit board is often relatively large. In addition, the design of the control module in the circuit board is more advanced. In addition to dedicated electronic control circuits, there is usually a dedicated battery management system. Since the circuits of traditional new energy vehicles are all designed on a single circuit board, if a problem occurs in one part of the circuit board, it will cause the entire electronic control system and battery management system to collapse.
[0003] In the prior art, application number CN202321973612.X discloses a combined circuit board for energy storage in new energy vehicles, which includes an upper motherboard and a lower motherboard placed parallel to each other. The upper motherboard and the lower motherboard are connected by a U-shaped plate on the side. This circuit board has a smaller flat area, making it easier to install inside the car and facilitating partial disassembly and replacement, which greatly reduces maintenance costs. The circuit board has a good cooling effect at high temperatures and lower cooling energy consumption.
[0004] Although the above technical solution uses a U-shaped plate to connect the two main circuit boards, the connection between the connecting piece and the connecting piece is only through sliding contact to conduct current. The vibration generated during vehicle operation can easily lead to poor contact between the connecting piece and the connecting piece, resulting in the failure of the electric control of the new energy vehicle. In addition, the fixed installation space between the circuit boards reduces the versatility. Therefore, we need to propose a combined circuit board for energy storage in new energy vehicles. Summary of the Invention
[0005] The purpose of this invention is to provide a modular circuit board for energy storage in new energy vehicles. By setting a locking structure, the positioning effect of the circuit board is improved, so as to avoid the circuit board from loosening due to vibration generated during vehicle operation, thereby improving the stability of circuit board installation. At the same time, the installation spacing of the connection structure is adjustable, which is suitable for different automotive installation spaces, thus improving practicality and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined circuit board for energy storage in new energy vehicles, comprising:

Both ends of the bidirectional lead screw are threadedly connected to movable seats. A support rod is rotatably mounted between each of the two sets of fixed seats and the two sets of movable seats.
[0011] Preferably, the connecting housing includes an outer housing and an inner housing, the inner housing is slidably inserted into the open end of the outer housing, and a rectangular groove is provided on one side of the outer housing for the end of the worm gear to pass through.
[0012] Preferably, one side of the mounting plate has a circuit board mounting groove for inserting the circuit board body, and both sides of the circuit board mounting groove have side grooves for sliding and storing the block, and the wing screw is rotatably disposed in the side groove.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-5 This invention provides a technical solution: a combined circuit board for energy storage in new energy vehicles, comprising:
[0026] The connecting housing 3 and the mounting plates 2 set at both ends of the connecting housing 3 are provided. The connecting housing 3 is provided with an adjustable connecting component 4 for adjusting the distance between the two sets of mounting plates 2, so as to realize the stable assembly of the circuit board body 1 and the flexible distance adjustment to adapt to different usage requirements.
[0027] The circuit board body 1 is inserted into one side of each of the two sets of mounting plates 2, and the locking components 5 are set on both sides of the mounting plate 2 to lock the circuit board body 1 to prevent it from falling off, thereby realizing the positioning and assembly of the circuit board body 1.
[0028] The locking assembly 5 includes a wing screw 51 and a block 52. One side of the block 52 has a screw hole 53 for mounting the wing screw 51, and the other side of the block 52 has multiple sets of teeth 54. The multiple sets of teeth 54 are all triangular prisms and are equidistantly arranged. By rotating the wing screw 51 on the mounting plate 2, the position of the block 52 can be easily adjusted so that the teeth 54 on the block 52 can be embedded in the 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 travel.
[0029] The adjustable connection assembly 4 includes multiple sets of bearing seats 41, a worm gear 44, and two sets of fixed seats 47. A bidirectional lead screw 42 is rotatably mounted on the multiple sets of bearing seats 41. A worm wheel 43 that meshes with the worm gear 44 is provided at the middle of the outer side of the bidirectional lead screw 42. Both ends of the bidirectional lead screw 42 are threadedly connected to movable seats 45. A support rod 46 is rotatably mounted between the two sets of fixed seats 47 and the two sets of movable seats 45. The threads at both ends of the bidirectional lead screw 42 are in opposite directions. The movable seats 45 at both ends will move towards or away from each other as the lead screw rotates. The movement of the movable seats 45 drives the two sets of fixed seats 47 to move through the support rod 46, thereby adjusting the distance between the two sets of mounting plates 2. The distance 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 combined circuit board.
[0030] The worm gear 43 and worm 44 transmission have self-locking properties, which can accurately adjust the mounting plate 2 to the required spacing position and remain stable after adjustment. The spacing will not be easily changed by external force, which improves the accuracy and reliability of adjustment. Multiple sets of bearing seats 41 ensure the stable rotation of the bidirectional lead screw 42. The support rod 46 plays a supporting and connecting role between the fixed seat 47 and the moving seat 45, so that the entire structure remains stable during the adjustment process and can withstand a certain amount of external force.
[0031] The connecting housing 3 includes an outer housing 31 and an inner housing 32. The inner housing 32 is slidably inserted into the open end of the outer housing 31. A rectangular groove 33 is provided on one side of the outer housing 31 for the end of the worm gear 44 to pass through. The outer housing 31 and the inner housing 32 can protect the adjustable connecting component 4, thereby improving the service life of the adjustable connecting component 4 and preventing damage to the adjustable connecting component 4. At the same time, when adjusting the spacing of the mounting plate 2, the inner housing 32 will slide inside the outer housing 31 as the mounting plate 2 moves.
[0032] The mounting plate 2 has a circuit board mounting slot 21 on one side for the circuit board body 1 to be inserted. Both sides of the circuit board mounting slot 21 have side slots 23 for the block 52 to be slidably stored. The wing screw 51 is rotatably set in the side slot 23. The side slot 23 facilitates the storage of the block 52 and restricts 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.
[0033] One end of the upper surface of the mounting plate 2 is provided with a connection terminal 25. The circuit board mounting groove 21 is provided with multiple sets of contact plates 24 that are electrically connected to the circuit board body 1 on one side adjacent to the two sets of side grooves 23. Multiple sets of storage grooves 22 are provided on the top of the circuit board mounting groove 21. The circuit board body 1 is electrically connected to the external circuit through the connection terminal 25 and contact plates 24 on the mounting plate 2. At the same time, the connection terminal 25 and contact plates 24 ensure the reliable connection between the circuit board and the external circuit, and guarantee the transmission of electrical energy and the transmission of signals.
[0034] It also includes a pre-positioning component 6 disposed within multiple sets of storage slots 22. The pre-positioning component 6 includes a telescopic rod 61, a spring 62, and a retaining ball 63. The telescopic rod 61 is fixedly connected to the top of the storage slot 22, the spring 62 is sleeved on the outside of the telescopic rod 61, and the retaining ball 63 is fixedly connected to the lower end of the telescopic rod 61 and protrudes from the storage slot 22. When the circuit board body 1 is inserted into the circuit board mounting slot 21, the circuit board body 1 presses against the retaining ball 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 retaining ball 63 embeds into the groove on the upper surface of the circuit board body 1, thereby achieving the pre-positioning of the circuit board body 1. This facilitates the subsequent operation of the locking component 5 and improves installation efficiency.
[0035] The upper surface of the circuit board body 1 is provided with grooves for multiple sets of retaining beads 63 to be inserted. Both sides of the circuit board body 1 are provided with tooth grooves for teeth 54 to be inserted. The retaining beads 63 can also prevent the circuit board body 1 from shaking or shifting during installation to a certain extent, thus ensuring the accuracy of installation.
[0036] In use, first, by rotating the worm 44 of the adjustable connecting component 4, the worm gear 43 and the worm 44 drive the bidirectional lead screw 42 to rotate, causing the moving seat 45 to move along the bidirectional lead screw 42. The distance between the two sets of mounting plates 2 is adjusted by the support rod 46 to match the size of the circuit board body 1. Then, the circuit board body 1 is inserted into the circuit board mounting slot 21 of the mounting plate 2. The locking ball 63 of the prepositioning component 6 is embedded into the groove of the circuit board body 1 under the action of the spring 62 to achieve initial positioning. Then, the wing screw 51 of the locking component 5 is rotated to drive the block 52 to move, so that the teeth 54 are embedded into the tooth groove on the circuit board body 1, completing the firm fixation of the circuit board body 1. The circuit board body 1 is electrically connected to the external circuit through the connecting terminal 25 and the electrical contact piece 24 on the mounting plate 2 to ensure the stable operation of the circuit board in the automotive energy storage system.
[0037] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
