[0026] In this embodiment, the pressing component drives the extrusion component, so that the extrusion component drives the locking component to lock the power module 2 inside the installation frame 1.

[0027] Furthermore, a locking block 16 is provided at the rear end of the power module 2 at a position corresponding to the locking assembly. The locking assembly includes a snap block 14. The locking block 16 is provided with a snap groove at a position corresponding to the snap block 14.

[0028] Furthermore, the pushing assembly includes a fixing frame 4, a connecting plate 9, a pressing column 11, a limiting rod 12 and a limiting spring 13. The fixing frame 4 is fixedly installed on the open side of the rear end of the mounting frame 1. The fixing frame 4 is in a "cross" shape. The end of the fixing frame 4 is fixedly connected to the mounting frame 1. The connecting plate 9 is disc-shaped. The connecting plate 9 is arranged in the middle of the side of the fixing frame 4 close to the mounting frame 1. The pressing column 11 is fixedly installed on the end of the connecting plate 9 close to the fixing frame 4. The pressing column 11 slides through the fixing frame 4 and extends out of the mounting frame 1. The pressing column 11 can move back and forth on the fixing frame 4. A plurality of limiting rods 12 are arranged in a ring shape on the side of the connecting plate 9 close to the fixing frame 4. The limiting rod 12 slides through the fixing frame 4. A plurality of limiting springs 13 are arranged in a ring shape between the connecting plate 9 and the fixing frame 4. The limiting spring 13 and the limiting rod 12 are arranged at intervals from each other.

[0029] In this embodiment, by providing a plurality of groups of limiting rods 12 , the connection disk 9 can be effectively limited to avoid rotation or deviation of the connection disk 9 .

[0030] In this embodiment, a plurality of sets of limiting springs 13 are provided so that after the pressing column 11 is pressed, the limiting springs 13 can reset the connecting disk 9 .

[0031] Furthermore, the extrusion assembly includes an auxiliary rod 7, a connecting plate 10 and an extrusion block 17. Auxiliary rods 7 are fixed on the upper and lower sides of the connecting disk 9. The connecting disk 9 and the auxiliary rod 7 are fixedly connected to each other through the connecting plate 10. The extrusion block 17 is fixedly installed on the auxiliary rod 7 at a position corresponding to the snap block 14.

[0032] Furthermore, the lock assembly also includes a buckle adjustment groove 15, which is a trapezoidal slot. The buckle adjustment groove 15 is opened on the buckle block 14 and is directly opposite to the corresponding extrusion block 17. The top of the buckle adjustment groove 15 is inclined so that the buckle adjustment groove 15 gradually widens in the direction approaching the extrusion block 17. The inclined surface on the buckle adjustment groove 15 corresponds to the position of the extrusion block 17, and the inclination angle of the inclined surface of the buckle adjustment groove 15 is adapted to the inclination angle of the inclined surface of the extrusion block 17.

[0033] In this embodiment, by pressing the pressing column 11, the connecting plate 9 drives the extrusion block 17 on the auxiliary rod 7 to move toward the direction close to the buckle block 14, and the inclined surface on the extrusion block 17 and the inclined surface on the inner side of the buckle adjustment groove 15 on the buckle block 14 are contacted and squeezed, so that the buckle block 14 moves away from the locking block 16 and separates from the buckle groove on the locking block 16, thereby completing the disassembly of the power module 2. Conversely, by releasing the pressing column 11, the buckle block 14 moves toward the side close to the locking block 16, thereby completing the installation and locking of the power module 2.

[0034] Furthermore, the lock assembly further includes an auxiliary block 3, a snap spring 8, a limiting hole 18 and a limiting block 19. The auxiliary block 3 is fixedly mounted on the outside of the mounting frame 1. The position of the auxiliary block 3 corresponds to the position of the snap block 14. The mounting frame 1 is provided with a limiting hole 18 directly opposite to the auxiliary block 3. The limiting block 19 is provided in the limiting hole 18. The limiting block 19 is fixedly connected to the snap block 14. The snap spring 8 is fixedly mounted on one end of the limiting block 19 away from the snap block 14. The snap spring 8 is fixedly mounted on the auxiliary block 3 at one end away from the limiting block 19. In this embodiment, a blind hole for accommodating the snap spring 8 is provided on the auxiliary block 3, and the corresponding end of the snap spring 8 extends into the blind hole.

[0035] In this embodiment, after the extrusion block 17 is disengaged from the buckle adjustment groove 15 , the buckle spring 8 can effectively drive the buckle block 14 to reset.

[0036] Furthermore, the limiting hole 18 is a cross-shaped slot hole, the limiting block 19 is a cross-shaped block, and the limiting block 19 and the limiting hole 18 are adapted to each other.

[0037] In this embodiment, the limiting hole 18 and the limiting block 19 arranged in a "cross" shape can effectively limit the angle of the snap block 14, avoid the occurrence of deviation of the snap block 14, and effectively improve the locking installation effect of the power module 2.

[0038] Furthermore, movable grooves 6 are provided on both sides of the inner wall of the installation frame 1. The movable grooves 6 are strip-shaped slots. Adjusting rods 5 are fixedly installed at the positions corresponding to the movable grooves 6 on both sides of the connecting plate 9. The adjusting rod 5 is movably extended to the inside of the movable groove 6 on the corresponding side at one end away from the connecting plate 9. Extrusion arc plates 22 are arranged at intervals on the inner side of the movable groove 6. The extrusion arc plates 22 are arc-shaped plates that can undergo elastic deformation. The middle part of the extrusion arc plates 22 protrudes toward the side close to the power module 2. A pushing rod 20 is arranged on the inner side of the movable groove 6. A plurality of pushing blocks 21 are fixedly installed on the pushing rod 20 at intervals. The pushing blocks 21 are located on the side of the corresponding extrusion arc plate 22 away from the adjusting rod 5. The number of the pushing blocks 21 matches the number of the extrusion arc plates 22. One end of the extrusion arc plate 22 away from the adjusting rod 5 is fixedly connected to the corresponding pushing block 21, and the other end is fixedly connected to the inner wall of the movable groove 6, and the pushing rod 20 is fixedly installed on the adjusting rod 5.

[0039] In this embodiment, when the pressing column 11 is pushed, the connecting disk 9 will drive the adjusting rod 5 to move in the movable groove 6, and then the pushing rod 20 will drive the pushing block 21 to move in the movable groove 6, so that the pushing block 21 drives the extrusion arc plate 22 to adapt to the deformation. One end of the extrusion arc plate 22 is fixed by the movable groove 6, and the other end moves synchronously with the pushing rod 20 through the pushing block 21. Under the force of the extrusion arc plate 22 that can deform, the arc surface of the extrusion arc plate 22 gradually changes to a plane, so that the power module 2 can be smoothly inserted into the installation frame 1. At the same time, when the power module 2 is locked and installed, the connecting disk 9 is reset to drive the pushing block 21 to return to the specified position on the inner side of the movable groove 6, so that the extrusion arc plate 22 protrudes toward the side close to the power module 2 to squeeze the side wall of the corresponding position of the power module 2, which can effectively complete the limitation of the power module 2 and greatly improve the stability of the power module 2 after installation.

[0040] The working principle and use process of the utility model are as follows: when in use, during installation, the pressing column 11 is pushed so that the pressing column 11 drives the connecting plate 9 and the auxiliary rod 7 on the connecting plate 9 to approach the side of the snap block 14, so that the extrusion block 17 and the snap adjustment groove 15 on the snap block 14 are correspondingly squeezed, thereby causing the snap block 14 to shrink toward the side close to the auxiliary block 3. At this time, the power module 2 is inserted into the interior of the installation frame 1 through the front end of the installation frame 1 until the rear end side wall of the power module 2 and the snap block 14 at the rear end of the inner side of the installation frame 1 are in contact, and then the pressing column 11 is released, so that the extrusion block 17 and the snap adjustment groove 15 on the snap block 14 are disengaged, thereby causing the snap block 14 to reset and snap onto the lock block 16 at the corresponding position on the power module 2, thereby completing the installation of the power module 2.

[0041] By simply pressing and releasing the pressing column 11, the extrusion block 17 can be squeezed and disengaged from the buckle adjustment groove 15 on the buckle block 14, thereby driving the buckle block 14 to disengage from the locking block 16 or buckle into the locking block 16, thereby greatly improving the installation efficiency of the power module 2.

[0042] The adjusting rod 5 and the pushing rod 20 are driven to move in the movable groove 6 through the connecting disk 9, so that the pushing block 21 drives the extrusion arc plate 22 to deform. When the power module 2 is installed, the connecting disk 9 is reset so that the pushing rod 20 inside the movable groove 6 drives the pushing block 21 to reset, so that the extrusion arc plate 22 protrudes toward the side close to the power module 2, thereby effectively locking and limiting the power module 2, thereby greatly improving the installation stability of the power module 2.

[0043] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
