[0015] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0016] A power battery box that is easy to hoist includes a lower housing 1 and an upper housing 2 mounted on the lower housing 1. The lower housing 1 and the upper housing 2 are connected by bolts and nuts, and the battery is located between the lower housing 1 and the upper housing 2.

[0017] The lower housing 1 has ear plates 3 installed on its front and rear sides respectively, and a fixing plate 4 connected to its rear end. The fixing plate 4 has hoisting holes 5 on its middle part and on both sides of the ear plates 3 respectively.

[0018] In this utility model, the three lifting holes 5 form three lifting points, and each lifting hole 5 can be threadedly connected to a lifting ring 13.

[0019] The hoisting hole 5 is a stepped hole, which includes an upper hole 6 and a lower hole 7 coaxial with the upper hole 6. The upper hole 6 is connected to the lower hole 7, and the inner diameter of the upper hole 6 is larger than the inner diameter of the lower hole 7.

[0020] The thickness of the ear plate 3 is D1, and 20mm≤D1, while D1 is less than the height of the lower shell 1, and the stepped hole passes through the ear plate 3.

[0021] The depth of the upper hole 6 is D2, and 15mm≤D2, while D2 is less than D1. In application, we can take D1=25mm and D2=18mm.

[0022] The upper hole 6 has an internal thread on its inner wall, and a threaded sleeve 8 is installed on the internal thread of the upper hole 6. The outer and inner walls of the threaded sleeve 8 are respectively threaded. The lower hole 7 is a smooth hole.

[0023] The outer wall of the threaded sleeve 8 is threaded to the inner wall of the upper hole 6. When installing the threaded sleeve 8 on the lower housing 1, it is only necessary to thread the three threaded sleeves 8 into the upper holes 6 of the three lifting holes 5 respectively.

[0024] The inner wall of the screw sleeve 8 is threadedly connected to the screw of the lifting eye 13. When this utility model needs to be lifted, we only need to thread the screws of the three lifting eye 13 to the inner walls of the screw sleeves 8 in the three upper holes 6 respectively.

[0025] The fixing plate 4 has several fixing holes 11 on both sides of the lifting hole 5. The fixing plate 4 of this utility model is connected to the vehicle body through the lifting hole 5 and the several fixing holes 11.

[0026] A plurality of reinforcing ribs 12 are installed at intervals along the length of the fixing plate 4 between the fixing plate 4 and the lower housing 1. By providing reinforcing ribs 12 between the fixing plate 4 and the lower housing 1, this utility model can effectively enhance the supporting strength of the fixing plate 4.

[0027] Reinforcing ribs 12 are installed between the ear plates 3 on both sides and the side walls of the lower housing 1. By installing several reinforcing ribs 12 between the ear plates 3 and the lower housing 1, the utility model can effectively enhance the supporting strength of the ear plates 3.

[0028] At least one side of the ear plate 3 has an ear plate positioning hole 9, and the fixing plate 4 has a fixing plate positioning hole 10. By providing the ear plate positioning hole 9 and the fixing plate positioning hole 10, this invention enables positional positioning during installation, making alignment easier. In application, the vehicle body is equipped with two positioning pins corresponding to the ear plate positioning hole 9 and the fixing plate positioning hole 10, respectively. These two positioning pins can be inserted into the ear plate positioning hole 9 and the fixing plate positioning hole 10 to achieve installation positioning.

[0029] The fixing plate positioning hole 10 is an elongated hole. By designing the fixing plate positioning hole 10 as an elongated hole, this utility model makes it easier for two positioning pins on the vehicle body to be inserted into the ear plate positioning hole 9 and the fixing plate positioning hole 10 at the same time.

[0030] Working principle of the utility model: Before hoisting, first thread the three threaded sleeves 8 into the upper holes 6 of the three hoisting holes 5 respectively, and then thread the three lifting rings 13 into the three threaded sleeves 8 respectively. At this time, the three lifting rings 13 are connected to the lower housing 1 through the three threaded sleeves 8 respectively. Then, the lifting tool is connected to the three lifting rings 13 through the hooks on the three lifting chains respectively, and the positioning pins are inserted into the positioning holes on the ear plate 3 and the fixing plate 4 respectively. Then, the utility model is hoisted to the installation position using a lifting device and slowly lowered so that the ear plate positioning hole 9 and the fixing plate positioning hole 10 are aligned with the two positioning pins on the vehicle body. First, the two positioning pins on the vehicle body are inserted into the ear plate positioning hole 9 and the fixing plate positioning hole 10 respectively, and then the lower housing 1 is placed on the vehicle body. Then remove the lifting device and take the three lifting rings 13 off the corresponding screw sleeves 8. At this time, the three stepped holes and the fixing holes 11 on the fixing plate 4 are aligned with the corresponding mounting holes on the vehicle body. Finally, insert the fixing bolts into the stepped holes and the mounting holes on the vehicle body and the fixing holes 11 and the mounting holes on the vehicle body to realize the fixed installation of this utility model on the vehicle body.

[0031] When the battery enclosure needs to be disassembled later, we only need to first remove the fixing bolts in the step hole and the mounting hole on the vehicle body, and the bolts in the fixing hole 11 and the mounting hole on the vehicle body. Then, install the three lifting rings 13 onto the three threaded sleeves 8, and connect them to the three lifting rings 13 through the hooks on the three lifting chains. Finally, lift it with a lifting tool. It is very convenient, time-saving and labor-saving.
