[0023] Reference Figures 1-8 The present invention provides a heating plate for an automotive lithium battery pack, comprising a battery pack housing 1, a side panel 2, a battery pack 3, and a heating plate body 4. The battery pack 3 is mounted within the battery pack housing 1, which has an opening on which the side panel 2 is removably mounted. A second bolt 16 is threadedly connected to the side panel 2, and a threaded hole adapted for the second bolt 16 is formed in the battery pack housing 1, and the second bolt 16 is threadedly connected to the threaded hole. An assembly plate 5 is mounted on the side of the side panel 2 near the battery pack 3. A docking block 8 is mounted on the side of the side panel 2 near the assembly plate 5. A first clamping block 9 is mounted on the side of the assembly plate 5 near the side panel 2, and a slot adapted for the docking block 8 is defined within the first clamping block 9. The docking block 8 is engaged within the slot, and an inserting block 10 is mounted within the slot. The docking block 8 has a socket adapted for the inserting block 10, and the inserting block 10 is inserted into the socket.

[0024] In this embodiment, two limiting plates 6 are installed on the side of the assembly plate 5 close to the battery pack 3. The heating plate body 4 is disposed between the two limiting plates 6 and is in contact with the battery pack 3. The limiting plates 6 are provided with a locking member for locking the heating plate body 4. A slide groove is provided on the limiting plate 6, and the locking member includes a slider 11, a first spring 12, a connecting block 13, and a positioning plate 14. The slider 11 is slidably disposed within the slide groove, the first spring 12 is mounted on the side of the slider 11 close to the heating plate body 4, the connecting block 13 is mounted on the end of the first spring 12 away from the slider 11, the positioning plate 14 is mounted on the connecting block 13 and abuts against the heating plate body 4, and a first bolt 15 is threadedly connected to the slider 11 and pressed against the limiting plate 6.

[0025] Through the design of the assembly plate 5 and the locking piece, in order to facilitate the assembly of the heating plate body 4, the first clamping block 9 on the assembly plate 5 can be sleeved on the docking block 8, so that the docking block 8 is engaged in the card slot, and at the same time the plugging block 10 on the first clamping block 9 can be plugged into the jacking hole opened on the docking block 8, thereby completing the installation of the assembly plate 5, and then the heating plate body 4 is clamped between the two limit plates 6, so that the slider 11 slides in the slide groove opened on the limit plate 6, so that the positioning plate 14 on the connecting block 13 is tightly against the heating plate body 4. When the plate body 4 is in abutment, the first spring 12 between the connecting block 13 and the slider 11 is squeezed, and the generated reaction is applied to the heating plate body 4 through the positioning plate 14, and then the position of the slider 11 in the slide groove is fixed by the first bolt 15, so that the heating plate body 4 is fixed between the two positioning plates 14, and then the side plate 2 is covered on the opening of the battery pack cover 1, and the side plate 2 is installed on the battery pack cover 1 by the second bolt 16. During the installation, the heating plate body 4 can be made to abut against the battery pack 3. This structure facilitates the assembly of the heating plate body 4.

[0026] In this embodiment, the assembly plate 5 is provided with a positioning member 7 for shaping the heating plate body 4. The assembly plate 5 has a through-notch with a fixing rod 17 mounted therein. The positioning member 7 includes a reinforcing plate 71 that is slidably mounted on the fixing rod 17. A plurality of reinforcing blocks 72 are mounted on the side of the reinforcing plate 71 that is adjacent to the heating plate body 4. Each of the plurality of reinforcing blocks 72 is provided with reinforcing ribs that abut against the heating plate body 4.
