[0002] Circuit boards for new energy vehicles are crucial components in the electrical systems of new energy vehicles. They undertake key functions such as power transmission, signal processing, and control command execution, acting like the "nerves" and "blood vessels" of a car to ensure the normal operation of all vehicle systems.

[0003] However, traditional circuit boards often adopt a distributed layout to meet different functional requirements, occupying a large amount of electrical control box space, resulting in low internal space utilization. Furthermore, there is a lack of convenient splicing and expansion structures between circuit boards. When the vehicle's functions are upgraded or new functional modules are added, it is difficult to achieve this by quickly splicing existing circuit boards. Often, it is necessary to redesign and install new circuit boards, which not only wastes resources but also increases R&D costs and time costs, limiting the flexible upgrade and optimization of the new energy vehicle's electronic control system. Therefore, a quick-release circuit board for new energy vehicles is proposed to solve the above problems. Summary of the Invention

An insert is fixedly connected to the outer surface of the connecting plate.

[0006] As a further description of the above technical solution: The clamping assembly includes a threaded rod with a fixed frame threaded through its surface and rotatably connected to its end. A slider is rotatably connected to the end of the threaded rod, and two sets of hinged rods are hinged to the inner sidewall of the slider.

[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] Reference Figures 1-3 The present invention provides an embodiment of a quick-release circuit board for new energy vehicles, comprising a circuit board 1, which is a new energy vehicle circuit board in the prior art, with resistors and modules on its surface. Both sides of the circuit board 1 are detachably mounted with connecting support legs 2 via clamping components 3. Both sides of the connecting support legs 2 are provided with mounting feet, which can fix it in the car's electronic control box. The inner sidewall of the connecting support legs 2 is provided with splicing components 4.

[0019] Reference Figures 2-4The splicing component 4 includes a fixed column 41. Cavities are provided on both sides of the connecting support leg 2. The outer wall of the fixed column 41 contacts the inner wall of the cavity, allowing for positioning and installation of the fixed column 41. A push block 42 is slidably connected to the inner wall of the top of the fixed column 41. The push block 42 can only slide up and down on the inner wall of the top of the fixed column 41 and cannot detach from its inner wall. A cavity is provided on the inner wall of the bottom end of the push block 42. Two sets of triangular blocks 43 contact the inner side wall of the cavity of the push block 42. When the push block 42 is pressed, it contacts the inclined surfaces of the two sets of triangular blocks 43, thereby squeezing the two sets of triangular blocks 43 closer together. A connecting plate 44 is fixedly connected to the bottom end of the outer wall of each set of triangular blocks 43. When the triangular blocks 43 are pressed by the push block 42, they synchronously drive the two sets of connecting plates 44 to move synchronously. 4. A sliding connection is made to the inner side wall of the fixed column 41. The outer arc surface of the fixed column 41 is provided with a sliding groove. The insert 46 passes through and is slidably connected to the inner wall of the sliding groove of the fixed column 41. The two sets of connecting plates 44 are elastically connected by a return spring 45. By providing a return spring 45, the position of the two sets of connecting plates 44 can be automatically reset after movement. At the same time, the triangular block 43 and the push block 42 are reset synchronously. The outer surface of the connecting plate 44 is fixedly connected to the insert 46. The side wall of the cavity of the connecting support leg 2 is provided with a slot. The outer wall of the insert 46 is inserted into the inner wall of the slot. The insertion between the two can fix the fixed column 41 as a whole inside the connecting support leg 2. At the same time, there are two sets of insert 46, one upper and one lower. The two sets of circuit boards 1 can be spliced ​​together vertically by the splicing component 4.

[0020] Reference Figure 2 and Figure 5The clamping assembly 3 includes a threaded rod 31, through which a fixing frame 32 is threadedly connected. The fixing frame 32 is fixedly connected to the outer sidewall of the connecting support leg 2. The function of the fixing frame 32 is to guide the position of the threaded rod 31 threadedly, so that the threaded rod 31 can only move back and forth threadedly on the inner wall of the fixing frame 32. A slider 33 is slidably connected to the inner sidewall of the connecting support leg 2. The end of the threaded rod 31 is rotatably connected to the slider 33. When the fixing frame 32 moves threadedly, it will drive the slider 33 to move synchronously. At the same time, since the slider 33 can only slide back and forth on the inner side of the connecting support leg 2, the rotation of the threaded rod 31 will not drive the slider 33 to rotate synchronously. Two sets of hinge rods 34 are hinged to the side wall. The two sets of hinge rods 34 are connected through and slidably connected to the inner walls of the upper and lower ends of the connecting support leg 2. The ends of the two sets of hinge rods 34 away from the slider 33 are hinged to clamping plates 35. When the slider 33 moves back and forth, it will drive the two sets of hinge rods 34 to move synchronously, thereby synchronously pulling the two sets of clamping plates 35 to move closer or further apart, thus fixing the connecting support leg 2 to the upper and lower sides of the circuit board 1. The bottom end of the clamping plate 35 is connected through and slidably connected to the inner wall of the connecting support leg 2. The contact surface between the clamping plate 35 and the circuit board 1 is made of rubber, which can effectively reduce the circuit influence of the circuit board 1. The inner side wall of the clamping plate 35 is in contact with the surface of the circuit board 1.

[0021] Working principle: During installation, rotating the threaded rod 31 causes it to move back and forth within the fixed frame 32 under the action of the threaded transmission, which in turn drives the slider 33 to move synchronously. When the slider 33 moves, it pulls the two sets of clamping plates 35 together through the hinge rod 34, thus firmly fixing the connecting support leg 2 to the upper and lower sides of the circuit board 1. During disassembly, rotating the threaded rod 31 in the opposite direction causes the slider 33 to move the hinge rod 34 and the clamping plates 35 in the opposite direction, moving the clamping plates 35 away from the circuit board 1, thereby quickly releasing the connection support leg 2 from the circuit board 1.

[0022] The splicing component 4 enables the vertical splicing of two sets of circuit boards 1. The outer wall of the fixing post 41 contacts the inner wall of the cavity on both sides of the connecting support leg 2 to complete the positioning and installation. Pressing the button 42 causes the button 42 to slide downward on the inner wall of the top of the fixing post 41. The inner wall of the cavity at its bottom contacts the inclined surface of two sets of triangular blocks 43, squeezing the triangular blocks 43 together. The triangular blocks 43 drive the connecting plate 44 fixed at its bottom to move synchronously. The connecting plate 44 slides on the inner side wall of the fixing post 41, and at the same time drives the insert 46 fixed on its outer surface to move. Since the outer arc surface of the fixing post 41 has a groove, the insert 46 slides in the groove. When the insert 46 moves to align with the slot on the side wall of the cavity of the connecting support leg 2, under the action of the return spring 45 between the two sets of connecting plates 44, the insert 46 is inserted into the slot, and the fixing post 41 is firmly fixed inside the connecting support leg 2, realizing the splicing of two sets of circuit boards 1 through the connecting support leg 2.

[0023] When disassembling the assembled circuit board 1, press the button 42 again. The button 42 squeezes the triangular block 43, causing the triangular block 43 to drive the connecting plate 44 and the insert 46 to move inward against the elastic force of the return spring 45. The insert 46 disengages from the slot of the connecting support leg 2, releasing the fixing post 41 from the fixing of the connecting support leg 2. At this time, the two sets of assembled circuit boards 1 can be separated.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
