[0033] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0034] like Figures 1 to 9 As shown, the present invention discloses a battery pack chassis, which includes a chassis body 1; the chassis body 1 includes a chassis body 11 and a chassis cover 12 covering the opening of the chassis body 11; at least two opposite sides of the chassis body 11 are provided with recessed handle grooves 111, and the inside of the handle grooves 111 is equipped with a first screw 13 that is locked with the chassis cover 12.

[0035] In the embodiment of the present invention, the present invention is provided with recessed handle grooves 111 on at least two opposite sides of the case body 11 of the chassis body 1. The handle grooves 111 can facilitate people to apply force and carry the chassis body 1, and the handle grooves 111 are recessed and not easy to hook people's clothes; in addition, the handle grooves 111 are equipped with first screws 13 locked with the case cover 12 to achieve the connection between the case body 11 and the case cover 12. Such an arrangement makes the first screws 13 hidden in the handle grooves 111, so that people cannot see the first screws 13 from the front of the chassis body 1 (that is, the side of the case cover 12 facing away from the case body 11), which helps to improve the integrity of the battery pack chassis of the present invention.

[0036] In an embodiment of the present invention, the side of the box body 11 may also be provided with at least two recessed electrical slots 112, and the interior of the electrical slots 112 is equipped with second screws 14 that are locked with the box cover 12; this can further improve the stability of the connection between the box body 11 and the box cover 12; in addition, the second screws 14 will be hidden in the electrical slots 112, so that people cannot see the second screws 14 from the front of the chassis body 1, thereby ensuring the integrity of the battery pack chassis of the present invention.

[0037] In an embodiment of the present invention, two recessed mounting grooves 113 may be provided on the bottom side of the case 11, and a third screw 15 may be provided inside the mounting groove 113 to be locked with the case cover 12; this can further improve the stability of the connection between the case 11 and the case cover 12; in addition, the third screw 15 will be hidden in the mounting groove 113, so that people cannot see the third screw 15 from the front of the chassis body 1 (that is, the side of the case cover 12 facing away from the case 11), thereby ensuring the integrity of the battery pack chassis of the present invention.

[0038] In an embodiment of the present invention, the side of the box cover 12 facing the box body 11 is provided with a plurality of waterproof nuts 121 for screwing the first screw 13, the second screw 14 and the third screw 15; and the side of the handle groove 111 facing the box cover 12 is provided with a first through-hole 1111 for the first screw 13 to pass through, and the first through-hole 1111 is a countersunk hole; the side of the electrical slot 112 facing the box cover 12 is provided with a second through-hole 1121 for the second screw 14 to pass through, and the second through-hole 1121 is a countersunk hole; the side of the installation slot 113 facing the box cover 12 is provided with a third through-hole 1131 for the third screw 15 to pass through, and the third through-hole 1131 is a countersunk hole. The present invention is configured in this way so that the first screw 13, the second screw 14 and the third screw 15 can be respectively sunk into the first through-hole 1111, the second through-hole 1121 and the third through-hole 1131, thereby preventing the first screw 13, the second screw 14 and the third screw 15 from being exposed and easily causing harm to people; in addition, the first screw 13, the second screw 14 and the third screw 15 are not easily visible when people look directly at the side of the chassis body 1.

[0039] In the embodiment of the present invention, a sealing ring 16 is directly sandwiched between the case cover 12 and the case body 11, and each of the first screw 13, the second screw 14, and the third screw 15 surrounds the sealing ring 16. This arrangement ensures the waterproof performance of the case body 1. The opening of the case body 11 may have a convex edge 115 that is inserted into the case cover 12. One side of the sealing ring 16 forms a contact flat surface 161 that contacts the convex edge 115, while the other side of the sealing ring 16 forms a contact curved surface 162 that contacts the case cover 12. This arrangement ensures sealing performance while preventing the sealing ring 16 from being crushed.

[0040] In the embodiment of the present invention, a flange 122 is formed around the periphery of the box cover 12; a spring buckle 116 is provided on the outer side of the convex edge 115 of the box body 11 to engage the flange 122, and the spring buckle 116 cooperates with the flange 122 to play a temporary fixing role.

[0041] In an embodiment of the present invention, the battery pack chassis of the present invention further includes two mounting brackets 2 connected to the chassis body 1 , and the mounting brackets 2 are used to suspend and fix the chassis body 1 , so that the present invention also has a suspension function.

[0042] In the embodiment of the present invention, the mounting bracket 2 includes intersecting hanging edges 21 and supporting edges 22. The supporting edges 22 of the two mounting brackets 2 are inserted into the mounting slots 113 and are secured to the case 11 by mounting screws 3 that pass through the supporting edges from bottom to top, allowing the mounting brackets 2 to support the chassis body 1. The back of the case 11 is provided with hanging holes 114 corresponding to the hanging edges 21 of the two mounting brackets 2. The hanging edges 21 are provided with hanging portions 211 that engage with the hanging holes 114. This arrangement further enhances the supporting effect of the mounting brackets 2 on the chassis body 1. In addition, the supporting edges 22 and mounting screws 3 do not protrude from the bottom side of the case 11. Thus, the mounting brackets 2 and mounting screws 3 are not visible from the front of the case body 1, thereby improving the integrity of the battery pack case of the present invention.

[0043] In an embodiment of the present invention, the support edge 22 is provided with a through hole 221 for the mounting screw 3 to pass through. The through hole 221 is a countersunk hole so that the mounting screw 3 can be sunk into the through hole 221, thereby preventing the mounting screw 3 from being exposed and easily causing harm to people.

[0044] In the embodiment of the present invention, the hanging portion 211 is provided with a rib 2111 , and the hanging hole 114 is provided with a clamping edge 1141 for engaging with the rib 2111 ; such an arrangement can effectively prevent the hanging portion 211 from falling out of the hanging hole 114 .

[0045] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
