DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 3As shown, a 360V high-voltage range-extending battery device includes one or more main frames 1 stacked in sequence, the stacked main frames 1 are mutually engaged, one of the main frames 1 contains a battery pack Ⅰ2 and a PDU module pack 4, and the remaining main frames 1 are provided with a battery pack Ⅱ3, the number of battery packs in the battery pack Ⅱ3 is greater than the number of battery packs in the battery pack Ⅰ2, and the number of main frames 1 and battery pack Ⅱ3 is adjusted according to the needs of road vehicles. The bottom main frame 1 contains a battery pack Ⅰ2 and a PDU module pack 4, and the PDU module pack 4 includes a PDU box body, and a battery communication interface, a heating interface, an instrument communication interface, a battery positive interface, a battery negative interface, and an emergency switch are provided on one side of the PDU box body.

[0021] Both battery pack Ⅰ2 and battery pack Ⅱ3 include a battery box, in which several battery packs are arranged, and a communication interface, a heating interface, a battery positive interface, a battery negative interface and an MSD interface are arranged on one side of the battery box; a retaining edge 5 is arranged on the walls around the bottom of the battery box, and a plurality of bottom ribs 6 are arranged on the bottom of the battery box, and the two ends of the bottom ribs 6 cooperate with the fixing frame 9 to fix the side frame and the main frame 1. In this embodiment, the bottom ribs 6 include long bottom ribs and short bottom ribs arranged vertically and crosswise; the fixing frame 9 is a right-angle frame, one side wall is fixed to the bottom ribs 6 by bolts, and the other side wall is fixed to the main frame 1 by bolts. The vehicle communication on the PDU module pack 4 corresponds to the vehicle-mounted end with the instrument communication; the battery + and battery - on the battery pack Ⅰ2 and the battery pack Ⅱ3 are connected in series in sequence and then connected to the battery + and battery - of the PDU module pack 4.

[0022] It is understandable that the number of battery packs can be increased according to the scenario requirements. If a small battery is required, only the bottom layer can be selected (i.e., including battery pack I2 and PDU module pack 4); if a large battery is required, two or three layers can be added, i.e., including the bottom battery pack I2 and PDU module pack 4 and the upper battery pack II3.

[0023] In the present application, the main frame 1 includes a rectangular bottom plate 11, and a side frame 12 is arranged on the long side of the rectangular bottom plate 11. The side frame 12 includes a column 121 arranged at the end of the long side of the rectangular bottom plate 11, and the two columns 121 are connected by a crossbeam 122; a bracket 13 is arranged between the side frames 12 on both sides, and the two ends of the bracket 13 are detachably connected to the columns 121 corresponding to the side frames 12 on both sides. A guide sheet metal 7 is arranged at the bottom of the inner side of at least one side of the side frame 12, and the guide sheet metal 7 is arranged in contact with the inner wall of the column 121, and the retaining edge 5 enters the interior of the main frame 1 along the upper end surface of the guide sheet metal 7. Therefore, the battery pack can enter the main frame 1 by two assembly methods: hoisting from top to bottom or pushing from front to back. The guide sheet metal 7 serves as a push-installation guide rail to prevent the battery pack from colliding with the side frame 12 when entering the main frame 1.

[0024] In a specific embodiment, the bracket 13 is a C-shaped bracket, and the ears on both sides of the C-shaped bracket are respectively matched with the two corresponding columns 121. The upper end surface of the middle cross frame of the C-shaped bracket is flush with the upper end surface of the column 121, and the cross frame and the rectangular bottom plate 11 superimposed on the upper part are detachably fixed by fasteners. The bracket 13 of the uppermost main frame 1 is provided with a lifting ear 8 to facilitate the lifting of the battery device.

[0025] The top of the column 121 is provided with a limiting column 123, and the bottom is provided with a limiting hole corresponding to the limiting column 123. The column 121 is engaged with the limiting hole overlapped with the limiting column 123 to realize the stacking of the main frame 1. This structure ensures the stability between the stacked main frames 1 and the uniformity of the engaging position.

[0026] In order to ensure the aesthetics of the entire battery device and prevent the bolts on the column 121 from being exposed, an inner groove 1211 is provided on the upper part of the column 121, and a mounting hole is provided on the bottom wall of the inner groove 1211 to be fixed with bolts and ears on both sides of the C-shaped frame.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
