The number of batteries installed in each cabinet varies depending on power requirements. Batteries are sequentially placed on a support rack fixed to the inner wall of the cabinet and then secured to the rack individually using bolts and other fasteners. Due to the limited space within the cabinet, this installation method presents significant challenges for battery installation, reducing installation efficiency. Utility Model Content

[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] The embodiments of the present application disclose an AC / DC integrated power supply system.

[0027] Reference Figure 1 、 Figure 2 as well as Figure 3The AC / DC integrated power supply system includes a cabinet 1 and a battery 2 mounted within the cabinet 1. Multiple sets of support racks 3 are fixedly mounted on the inner sidewalls of the cabinet 1. In this embodiment, two sets of support racks 3 are used as an example. The two sets of support racks 3 are spaced apart along the height of the cabinet 1. The support racks 3 are arranged with three stepped platforms 30 arranged from top to bottom, with the heights of the three stepped platforms 30 increasing in sequence. Each battery 2 is placed on a stepped platform 30 of a corresponding height.

[0028] like Figure 3 、 Figure 4 As shown, a front door is pivotally mounted on the front of the cabinet body 1. A sliding plate 4 is mounted horizontally on a support frame 3. This sliding plate 4 is located on the side of the bottom battery 2 facing the door, and faces the outer sidewalls of the batteries 2 located at the same height on the bottom layer. Fastening bolts 31 are threadedly connected to the sidewall of the step 30 facing the door. Fastening bolts 31 penetrate the sliding plate 4 and are used to press the sliding plate 4 against the outer sidewalls of the batteries 2 located at the same height on the bottom layer.

[0029] like Figure 3 、 Figure 4 as well as Figure 5 As shown, two retaining rings 32 are fixedly mounted on the bottom of the support frame 3, symmetrically arranged on the left and right sides of the support frame 3. Two parallel guide rods 41 are fixedly mounted on the bottom of the sliding plate 4. The guide rods 41 are movably inserted into the respective retaining rings 32 along the sliding direction of the sliding plate 4. A baffle 42 is coaxially fixedly mounted on the end of the guide rod 41 away from the sliding plate 4. The outer diameter of the baffle 42 is larger than the inner diameter of the retaining ring 32. The sliding plate 4 is slidably mounted on the support frame 3 via the guide rods 41. When the sliding plate 4 is pulled away from the battery 2, the baffle 42 gradually approaches the retaining ring 32. When the baffle 42 moves and contacts the retaining ring 32, the baffle 42 blocks further movement of the sliding plate 4. This prevents the sliding plate 4 from completely detaching from the support frame 3 and limits the sliding distance of the sliding plate 4.

[0030] like Figure 3 、 Figure 4 as well as Figure 5 As shown, a plurality of baffles 40 are fixedly mounted on the sliding plate 4, each baffle 40 being arranged in a sequentially spaced arrangement along the length of the sliding plate 4. Each baffle 40 is inserted between two adjacent batteries 2 located on the bottom layer. The baffles 40 positioned between adjacent batteries 2 facilitate positioning during installation, making it easier for installers to accurately place the batteries 2 at the designated location on the step platform 30. Furthermore, they further enhance the securing and stability of the batteries 2.

[0031] like Figure 4As shown, two hand-held seats 43 are fixedly installed on the outer side wall of the sliding plate 4 away from the battery 2, and the hand-held seats 43 are symmetrically arranged on the left and right sides of the sliding plate 4. The hand-held seats 43 facilitate the sliding plate 4 to be pushed.

[0032] like Figure 3 、 Figure 4 as well as Figure 5 As shown, the system also includes a pressure plate 5 that vertically covers the top of the upper battery 2. The pressure plate 5 is located diagonally above the baffle 40 and has multiple sets of through-holes 50 extending through the pressure plate 5, corresponding one-to-one with the top terminals of the upper battery 2. The terminals located at the top of the battery 2 extend through their respective corresponding through-holes 50. The pressure plate 5 simultaneously covers the upper battery 2 at the same height. A plurality of gussets 44 are fixedly mounted on the baffle 40 and arranged in a sequentially spaced arrangement along the length of the pressure plate 5. The gussets 44 extend to one side of the pressure plate 5, toward the upper pressure plate 5.

[0033] like Figure 3 、 Figure 5 As shown, the gusset plate 44 is integrally formed with a plurality of partitions 440 respectively inserted between the upper batteries 2. The gusset plate 44 is provided with insertion slots 45 facing the outer edge of the pressure plate 5, and the outer edge of the pressure plate 5 is inserted and limited in each insertion slot 45.

[0034] like Figure 3 、 Figure 4 as well as Figure 5 As shown, a cover plate 6 is provided on the side of the pressure plate 5 away from the buckle plate 44. The cover plate 6 is located obliquely above the pressure plate 5, and the cover plate 6 and the pressure plate 5 are parallel to each other. The cover plate 6 is used to cover the top of each battery 2 located on the top layer and at the same height in the vertical direction. A plurality of connecting strips 7 are fixedly connected between the pressure plate 5 and the cover plate 6, and the connecting strips 7 are arranged in sequence and at intervals along the length direction of the cover plate 6. The pressure plate 5 and the cover plate 6 are connected and fixed to each other by the connecting strips 7. The cover plate 6 also has a plurality of through-holes 50 that correspond one-to-one to the terminal of the battery 2 on the top layer, and the terminal of the battery 2 on the top layer passes through their respective relative through-holes 50.

[0035] like Figure 6 As shown, a rear cabinet door 8 is rotatably provided on the back of the cabinet body 1, and a large number of heat dissipation holes 80 are passed through the rear cabinet door 8. The rear cabinet door 8 facilitates the installation personnel to install and remove the battery 2 located on the top layer. In addition, the heat dissipation performance of the cabinet body 1 is further improved by the heat dissipation holes 80 provided on the rear cabinet door 8.

[0036] The implementation principle is as follows: when installing the battery 2, the batteries 2 are first placed on the step platforms 30 of corresponding heights in sequence, and then the pressure plate 5 and the cover plate 6 are respectively covered on the top of the upper and top battery 2 from top to bottom, and then the sliding plate 4 is pushed horizontally until it fits into the outer wall of the bottom battery 2. At this time, the outer edge of the pressure plate 5 will be inserted and limited in the insertion groove 45 of the buckle plate 44. Under the blocking of the buckle plate 44, it can be ensured that the pressure plate 5 and the cover plate 6 are respectively limited on the top of their respective batteries 2, realizing the limitation of the upper and top battery 2, and finally the sliding plate 4 is locked on the supporting frame 3 by tightening the bolts 31. At this time, the batteries 2 on the upper and top layers will be stably and firmly pressed on the step platforms 30. In addition, the battery 2 on the bottom layer can also be stably and firmly pressed on the step platform 30 under the limitation of the sliding plate 4. The entire fixing process is convenient and quick, which greatly simplifies the installation steps and improves the efficiency of installation and maintenance.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
