DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Please refer to Figures 1-6 In the present application, the modular battery pack slide rail type blind plug installation system comprises an energy storage cabinet body 1, the inside of the energy storage cabinet body 1 comprises a control module 2 and vertically equidistantly arranged partition plates 3, the partition plates 3 divide the inside of the energy storage cabinet body 1 into a plurality of battery installation grooves 4, the battery installation grooves 4 are used for installing battery packs, the control module 2 is vertically arranged in the inside of the energy storage cabinet body 1, equidistantly arranged bidirectional buffering mechanisms 6 are arranged on the control module 2, blind plug connectors 5 are arranged on the bidirectional buffering mechanisms 6, the blind plug connectors 5 are used for connecting the insertion holes on the battery packs, two parallel first limiting sliding grooves 7 are arranged on the partition plates 3, sliding bars 8 are slidingly arranged in the first limiting sliding grooves 7, second limiting sliding grooves 9 are arranged on the sliding bars 8, limiting elastic members 10 are arranged in the second limiting sliding grooves 9, the limiting elastic members 10 are matched with the bottom corners of the inward one ends of the battery packs; the limiting elastic members 10 comprise first springs 101 and corner blocks 102, one end of the first spring 101 is fixedly connected with the inner wall of the second limiting sliding groove 9, the other end of the first spring 101 is fixedly connected with the corner block 102, and the bottom of the corner block 102 is slidingly connected to the inside of the second limiting sliding groove 9.

[0020] In the present application, the control module 2 in the inside of the energy storage cabinet body 1 is used for controlling and managing the operation of the energy storage cabinet body 1, and the battery installation grooves 4 divided by the partition plates 3 are used for installing the battery packs. When the battery pack is installed, first, the energy storage cabinet body 1 is opened, the two sliding bars 8 are pulled along the first limiting sliding grooves 7 to the position where they cannot be pulled any more, at this time, one half of the length of the two sliding bars 8 is extended out of the inside of the battery installation groove 4, then the two corners at the bottom of the inward one end of the battery pack are respectively aligned and placed on the two corner blocks 102, then the angle of the battery pack is made horizontal and the battery pack is pushed inward, the two corner blocks 102 limit the two sides of the battery, so that when the battery pack is pushed forward, the front end of the battery pack always keeps stable forward movement and cannot deviate, the connection precision is ensured, with the battery pack being pushed inward, the first spring 101 is stretched, the outer side surface of the corner block 102 is attached to the sliding bar 8, at this time, the pushing force continues to push and drive the sliding bar 8 to reset inward along the inside of the second limiting sliding groove 9, with the sliding bar 8 moving inward, the battery pack gradually contacts and connects with the blind plug connector 5, until the sliding bar 8 cannot move, at this time, the battery pack gradually contacts and completely connects with the blind plug connector 5.

[0021] And because the blind plug 5 is installed on the bidirectional buffering mechanism 6, when the blind plug 5 contacts the battery pack butt joint gap, the contact friction resistance between the two generates an instantaneous impact on the blind plug 5, so that the bidirectional buffering mechanism 6 deforms to absorb the impact, until the blind plug 5 is completely inserted into the butt joint hole of the battery pack, at this time the bidirectional buffering mechanism 6 still maintains a certain deformation amount, that is, the blind plug 5 is kept a certain pushing force, so that it is more stable to butt joint with the battery pack hole, and when the energy storage cabinet 1 is subjected to external vibration, the elastic support of the bidirectional buffering mechanism 6 enables the blind plug 5 to vibrate synchronously with the battery pack, reduces deformation damage, ensures connection quality, so that the device has the advantages of soft connection of the blind plug position, butt joint buffering, protection of the joint part, reduction of direct hard contact between the battery pack and the inner wall of the installation groove, protection of the battery pack and prolongation of the service life of the battery pack, solving the problem in the prior art that the blind plug is generally rigidly fixed in the energy storage cabinet, and when butt joint, if there is a knock deviation, forcibly inserting the battery pack can easily damage the blind plug and the butt joint hole structure on the battery pack, and when the battery pack is pulled out, the battery pack directly hard contacts and slides with the inner wall of the energy storage cabinet groove, which not only is laborious to move, but also easily causes damage to the surface of the battery pack and reduces the service life.
