Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a large-size power module pull-out aid. Background Technology

[0002] Currently, the power section of modular vehicle-mounted integrated power products adopts a fixed-power modular design, which tightly installs multiple power modules inside the chassis. This saves internal space while allowing multiple power modules to be used in parallel, maximizing efficiency.

[0003] Power modules generally require the use of a puller for quick insertion and removal. The existing Chinese patent "A Chassis Functional Module Puller", patent number: CN201920758664.2 discloses a puller for facilitating the insertion and removal of chassis functional modules. However, this puller is only suitable for lightweight and small power modules. When dealing with heavy and large power modules, using this puller not only makes it difficult to remove the power module, but excessive force in pulling the puller may also injure the operator or the equipment itself.

[0004] Therefore, it is necessary to provide a large-size power module puller to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a large-size power module plug-in / plug-out aid that enables easy plugging and unplugging of large-size power modules.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A large-size power module puller includes a first puller and a second puller, which are symmetrically arranged on the outer side of the bottom back of the power module. The puller includes a puller body, one end of which is a handle end and the other end is a rotating end. The rotating end has two symmetrically installed lugs on the side facing the power module. Each lug has a through pin hole, and a torsion spring is provided between the two lugs. A fixing bolt passes through the torsion spring and the pin holes of the two lugs from the outside and is connected to the power module. The end of the rotating end has a mounting groove, in which a roller is rotatably connected. Each of the first and second pullers has a pull rod on the opposite side of the handle end. Each pull rod has an elastic protrusion on the side away from the handle end. A sleeve is provided between the two pull rods, which is fitted around the outer circumference of the pull rods. The sleeve has multiple through holes along its length that mate with the elastic protrusions.

[0008] Preferably, each end of the torsion spring extends a support leg, one support leg is fixed to the puller body, and the other support leg is fixed to the power module.

[0009] Preferably, each pull rod is provided with two elastic protrusions, and the sleeve is provided with two rows of through holes.

[0010] Preferably, the power module has receiving cavities on both sides for respectively installing the first extraction aid and the second extraction aid.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. By symmetrically installing the first and second pullers on both sides of the power module, the lever arm is increased, making it easier to pull out large power modules without damaging the equipment; by using the matching combination of pull rod and sleeve to connect the handle ends of the first and second pullers, the operating area is increased, avoiding hand discomfort during operation and reducing the difficulty of operation.

[0013] 2. Install elastic protrusions on the pull rod, and open multiple through holes on the sleeve to mate with the elastic protrusions. This allows for easy adjustment of the total length of the pull rod and sleeve for power modules of different widths, making this puller suitable for various specifications of power modules.

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixed connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, terms such as "upper", "lower", "bottom", and "top" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model. They should not be construed as limiting this utility model.

[0023] like Figures 1 to 5 As shown, a large-size power module pull-out aid includes a first pull-out aid and a second pull-out aid. The first and second pull-out aids are symmetrically installed in a receiving cavity on the bottom outer side of the back of the power module 1. The pull-out aid includes a pull-out aid body 2, one end of which is a handle end and the other end is a rotating end. The rotating end has two symmetrically installed lugs 3 on the side facing the power module. The lugs have through pin holes, and a torsion spring 4 is provided between the two lugs. Each end of the torsion spring extends into a support leg, and one support leg is fixed to the... On the main body of the pull-out aid, another support leg is fixed to the power module. The fixing bolt 5 passes through the pin holes of the torsion spring and the two support ears from the outside and is connected to the power module. The end of the rotating end is provided with a mounting groove, and a roller 6 is rotatably connected in the mounting groove. Pull rods 7 are installed on the opposite side of the handle ends of the first pull-out aid and the second pull-out aid. Two elastic protrusions 8 are provided on the side of the pull rod away from the handle end. A sleeve 9 is provided between the two pull rods. The sleeve is fitted around the outer circumference of the pull rod, and the sleeve has two rows of through holes 10 along the length direction that cooperate with the elastic protrusions.

[0024] The principle and usage of a large-size power module puller: The first and second pullers are respectively installed in the receiving cavity on the bottom outer side of the back of the power module. The two ends of a sleeve are respectively fitted onto the pull rods of the first and second pullers. Based on the width of the power module, a suitable through hole is selected on the sleeve, and the elastic protrusion is engaged in the through hole. When the power module needs to be pulled out of the chassis, press down on the pull rod and sleeve. Using the lever principle, the first and second pullers rotate around the fixing bolt, simultaneously causing the rollers to roll into contact with the chassis. Pulling the pull rod and sleeve allows the power module to be easily pulled out of the chassis. After use, the torsion spring's reset function repositions the first and second pullers back into the receiving cavities on both sides of the power module, preventing interference between the first and second pullers and other electrical components.

[0025] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
