Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Example 1

[0033] In a typical implementation of the present invention, Figure 1 As shown, a loader counterweight is provided, including a counterweight body 1, with raised structures 3 on both sides of the top of the counterweight body 1, a connecting plate 10 is provided on one side of the counterweight body 1 connected to the loader, a tool box and a battery box are connected to both sides of the connecting plate 10, and the bottoms of the tool box and the battery box are respectively raised on opposite sides, and the height, length and width of the two raised parts are set according to the actual installation situation of the loader, such as Figure 3 As shown, the battery box is configured as an upper and lower layered detachable connection structure, and the lower layer of the battery box and the counterweight body 1 are an integral structure.

[0034] It is understandable that the loader counterweight is generally achieved by pouring concrete to balance the weight of the loader, and the counterweight weight is adjustable by adjusting the density of the poured concrete. In this embodiment, by setting the protruding structures 3 on both sides of the top of the counterweight body 1, the bottom opposite sides of the toolbox and the battery box are respectively protruded toward each other, which can increase the filling space of the concrete inside the counterweight, thereby achieving a larger adjustable range of the counterweight weight and improving the applicability and practicality of the counterweight. In addition, the toolbox and the battery box are respectively connected on both sides of the loader counterweight, and the counterweight space is reasonably used, so that the function of the loader counterweight is more abundant.

[0035] In this embodiment, a pin connection hole 2 is provided on the top of the counterweight body 1. The pin connection hole 2 is located in the middle of the protruding structures 3 on both sides of the counterweight body 1. A traction pin can be installed in the pin connection hole 2 for towing the loader.

[0036] In addition, the connecting plate 10 is provided with a plurality of evenly distributed connecting holes 12 in the middle of the tool box and the battery box. The size and number of the connecting holes 12 can be selected according to the actual situation. The position setting of the plurality of connecting holes 12 can realize the stable connection of the counterweight to the loader to balance its weight. At the same time, a through hole 11 is provided in the middle of the plurality of evenly distributed connecting holes 12. In this embodiment, the through hole 11 is set in a rectangular shape. When the counterweight is connected to the loader, the fuel tank mounting bolt on the loader can pass through the through hole 11 to avoid interference between the installation of the counterweight and the loader.

[0037] In this embodiment, the upper layer of the battery box is the second battery box 14, and the lower layer of the battery box is the first battery box 13. The second battery box 14 is detachably connected to the first battery box 13 by a plurality of bolts 18, and both the first battery box 13 and the second battery box 14 are provided with a limit plate. By setting the lower layer of the battery box and the counterweight body 1 as an integral structure, the upper layer of the battery box is connected to the lower battery box body by bolts 18, and the overall structure is stable and has good consistency.

[0038] Further, such as Figure 4 As shown, the second battery box 14 is provided with a second battery box cover 25 on the top of the box body. Figure 2 As shown, a buffer strip 19 is provided at the contact portion between the second battery box 14 and the second battery box cover 25. In this embodiment, the buffer strip 19 can be made of rubber, which can achieve a certain sealing effect while preventing the vibration and bump generated during the operation of the loader, which may cause structural damage caused by friction and collision between the second battery box 14 and the second battery box cover 25. Figure 5 As shown, the inner side wall of the second battery box 14 is fixedly connected to the power switch fixing plate 24, which is used to limit and fix the power switch on the battery in the box.

[0039] Further, such as Figure 4 As shown, the second battery box cover 25 is provided with a power switch cover 15 and a second battery box handle 16, and the power switch cover 15 is provided with a knob lock 17, and the knob lock 17 is detachably connected to the power switch cover 15. Such an arrangement makes it convenient for the staff to operate the power switch of the battery, and the power switch fixing plate 24 can be used to install the power switch of the battery in the box to limit and fix the power switch on the battery.

[0040] like Figure 5As shown, the bottom of the second battery box 14 is connected with a first limiting plate 21 of the second battery box and a second limiting plate 22 of the second battery box, wherein the first limiting plate 21 of the second battery box and the second limiting plate 22 of the second battery box are both L-shaped plates and perpendicular to each other, and the first limiting plate 21 of the second battery box and the second limiting plate 22 of the second battery box are in contact with the battery on one side perpendicular to the bottom of the box, and a battery box wire hole 23 is also provided at the bottom of the second battery box 14.

[0041] In this way, a battery box wire hole 23 is provided on the bottom plate of the upper battery box for connecting the two layers of battery lines, and the line connection of the two batteries is placed inside the box to avoid damage to the line. At the same time, the upper and lower battery boxes are respectively provided with limit plates to limit and fix the batteries to avoid bumps during the operation of the loader causing the batteries to collide and be damaged inside the battery box. In other embodiments, the position of the first battery box limit plate 20 can be set corresponding to the upper and lower positions of the limit plate set in the second battery box, so that the upper and lower batteries can be conveniently connected. At the same time, the first battery box limit plate 20 can also be set according to actual conditions to ensure convenient connection and stable placement of the upper and lower batteries.

[0042] In this embodiment, the toolbox includes a toolbox body and a toolbox cover 5. A protruding structure of the body is provided on one side of the toolbox body connected to the toolbox cover 5. The toolbox cover 5 is rotatably connected to the protruding structure of the body through a hinge 6. The toolbox cover 5 is parallel to the top plane of the protruding structure of the body. The toolbox cover 5 is larger than the top plane of the protruding structure of the body and has a side folded down to wrap the outer side of the protruding structure of the body. In this way, the toolbox cover 5 is a clamshell type. The toolbox cover 5 is slightly wider than the protruding structure on the top of the body, so that the toolbox has a certain degree of sealing when it is closed, and can prevent rainwater from entering the body when the toolbox is opened.

[0043] Furthermore, a lock body 7 is provided on one side of the toolbox, and the lock body 7 is respectively connected to the toolbox body and the toolbox cover 5. The toolbox cover is provided with a toolbox handle 4, which is convenient for opening the toolbox and also allows the staff to grasp it and board the loader conveniently.
