[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-5 .

[0030] The utility model discloses a split type electric vehicle converter who includes mounting seat 1 and the shell 101 of sliding setting on mounting seat 1, one end of shell 101 is fixedly connected with fixed plate 102, the other end of shell 101 is slidably provided with movable plate 103, and the fixed plate 102 and movable plate 103 are provided with the clamping part 2 for clamping circuit board and the adjusting part 3 for distance adjustment according to circuit board model, and the mounting seat 1 is provided with the locking part 4 for locking shell 101.

[0031] Further, the adjusting part 3 can be guided by the slide rod 34 and driven by the screw rod 32, so that the distance between the movable plate 103 and the fixed plate 102 can be accurately adjusted, and circuit boards of different lengths can be adapted. In addition, the composite design of the slide rod 34 and the screw rod 32 can reduce the weight of the adjusting part 3 and the overall energy consumption under the premise of ensuring strength.

[0032] Further, the locking part 4 can be elastically reset by the second spring 42, and the locking rod 45 and the locking groove 44 can be matched, so that the shell 101 and the mounting seat 1 can be quickly disassembled and assembled, and the tensile strength can be improved. That is, after the locking plate 43 is overlapped with the end face of the mounting groove 105, the locking rod 45 is embedded in the locking groove 44 to realize the limitation in the height direction, and the disassembly and assembly efficiency is greatly improved. It should be noted that the spring damping structure can buffer the impact force generated by driving bumping to avoid the risk of poor contact or short circuit caused by locking failure.

[0033] Further, the locking part 4 can be elastically reset by the second spring 42, and the locking rod 45 and the locking groove 44 can be matched, so that the shell 101 and the mounting seat 1 can be quickly disassembled and assembled, and the tensile strength can be improved. That is, after the locking plate 43 is overlapped with the end face of the mounting groove 105, the locking rod 45 is embedded in the locking groove 44 to realize the limitation in the height direction, and the disassembly and assembly efficiency is greatly improved. It should be noted that the spring damping structure can buffer the impact force generated by driving bumping to avoid the risk of poor contact or short circuit caused by locking failure.

[0034] In addition, the bottom of the shell 101 is fixedly connected with two slide bars 104 in inverted T-shaped cross section, and the mounting seat 1 is provided with mounting grooves 105 matching the size of the slide bars 104. In this way, the inverted T-shaped cross section of the slide bars 104 and the mounting grooves 105 can ensure accurate guidance and anti-twisting ability when the shell 101 slides. The inverted T-shaped structure can limit the lateral displacement of the shell 101, avoid installation misalignment caused by vibration, and ensure stable docking of the circuit board and the external interface.

[0035] Specifically, the length of the mounting groove 105 is the same as that of the slide bar 104, and when the slide bar 104 is completely in the slide groove, the end face of the slide bar 104 and the end face of the shell 101 are flush with the end face of the mounting seat 1. Through such a design, the movement trajectory of the shell 101 along the mounting seat 1 can be strictly limited after the slide bar 104 is completely embedded in the slide groove, avoiding lateral deviation or inclination.

[0036] Secondly, the locking plate 43 overlaps the end face of the mounting groove 105, and the locking plate 43 is fixedly connected with a locking rod 45, and the mounting seat 1 is provided with a locking groove 44 matching the size of the locking rod 45. It should be noted that in specific implementation, the contact surface between the locking rod and the locking groove 44 can be coated with rubber or knurled to increase the friction and prevent the locking rod 45 from coming off the locking groove 44 in states other than disassembly.

[0037] Thirdly, the fixed plate 102 is fixedly connected with a motor 31 for driving the screw rod 32 to rotate, and the motor 31 is used to drive the screw rod 32 to rotate and drive the movable plate 103 to move to adapt to circuit boards of different lengths.

[0038] In addition, the two clamping plates 22 on the fixed plate 102 and the movable plate 103 are in close contact with each other in the initial state, which can ensure that the first spring 23 is in a compressed state when the two clamping plates 22 clamp the circuit board, ensuring that it can clamp the circuit board and play a certain buffering role in the vertical direction.

[0039] Further, the movable plate 103 is fixedly connected with a plurality of first sliding blocks 24 in T-shaped cross section, and the inner wall surface of the shell 101 is provided with a plurality of second sliding grooves 36 matching the size of the second sliding blocks 35. In this way, the stability of the movable plate 103 can be ensured.

[0040] The working principle of the split electric vehicle converter is based on the synergistic effect of elastic clamping, mechanical adjustment and composite locking. When the circuit board is placed between the fixed plate 102 and the movable plate 103, the symmetrical clamping plates 22 on the upper and lower surfaces are self-adapted to the surface of the circuit board under the elastic support of the first spring 23, forming a flexible clamping force, which can adapt to circuit boards of different thicknesses and avoid damage to components caused by rigid clamping. At the same time, the motor 31 drives the screw rod 32 to rotate, and the movable plate 103 is driven to slide along the slide rod 34 through the screw sleeve 33, so as to accurately adjust the distance between the fixed plate 102 and the movable plate 103, and adapt to circuit boards of different lengths. The shell 101 is slidably connected with the mounting groove 105 of the mounting seat 1 through the inverted T-shaped slide strip 104 at the bottom, and is rigidly constrained in the lateral displacement and torsion angle, so as to ensure the accurate butt joint of the shell 101 and the mounting seat 1. When the shell 101 slides to the preset position, the locking plates 43 on both sides of the mounting seat 1 are automatically reset under the elastic force of the second spring 42, the locking rods 45 are embedded in the locking grooves 44 to form mechanical limiting, and the spring damping is used to absorb vibration impact, so that the locking rods 45 are always in close contact with the bottom of the locking grooves 44, avoiding the risk of falling out caused by vehicle bumping or external force. Through the linkage design of elastic buffering, guiding limiting and composite locking, the efficient installation of the circuit board, the multi-size adaptation and the stable operation under complex working conditions are realized.

[0041] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
