[0033] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0034] According to an embodiment of the present invention, in a first aspect, a loader frame is provided, comprising a wing box 10, a connection assembly 20, a battery 30, and a counterweight 40. Two wing boxes 10 are provided, spaced apart from each other, each wing box 10 having at least two accommodating cavities 17 formed therein. The connection assembly 20 includes a first connection plate 21, the two sides of which are connected to the two wing boxes 10, respectively, and together with the two wing boxes 10, form an engine compartment. The battery 30 is disposed in one of the two wing boxes 10. A plurality of counterweights 40 are provided, with at least one counterweight 40 disposed in the other of the two wing boxes 10.

[0035] When the loader frame of this embodiment is applied, at least two accommodating cavities 17 are formed in the wing box 10, thereby forming a multi-box structure, effectively improving the structural strength of the wing box 10 and increasing the usable space in the wing box 10; by placing the battery 30 and the counterweight 40 in the two wing boxes 10, the space utilization rate of the wing boxes 10 on both sides is effectively improved, while the stability of the entire machine is greatly improved.

[0036] Specifically, in this embodiment, two accommodating cavities 17 are provided in each wing box 10 .

[0037] It should be noted that, in addition to the counterweight 40 and the battery 30 , mechanical components such as an oil cylinder may also be provided in the accommodating cavity 17 .

[0038] Of course, in other alternative embodiments, the number of the accommodating cavities 17 in the wing box 10 may also be three, four, etc.

[0039] Specifically, three counterweights 40 are provided, two of which are provided in one wing box 10, and the other counterweight 40 and the battery 30 are provided in the other wing box 10, so as to achieve the balance of the counterweights in the two wing boxes 10, improve the space utilization of the wing box 10, and enhance the stability of the whole machine, and make the layout of the whole machine more reasonable.

[0040] Specifically, a power switch 31 is further provided on the wing box 10 . The power switch 31 is provided close to the battery 30 so as to shorten the length of the cable from the battery 30 to the power switch 31 and save costs.

[0041] Furthermore, along the height direction of the loader frame, the battery 30 is arranged at a higher position in the accommodating cavity 17, which can prevent the battery 30 from being immersed in water when the vehicle wades forward, thereby increasing its service life.

[0042] Specifically, the loader frame further includes a rear bottom plate 92 . Along the height direction of the loader frame, the rear bottom plate 92 is disposed at the bottom of the wing boxes 10 and is welded to the bottoms of the two wing boxes 10 .

[0043] In one embodiment, the wing box 10 includes an outer wing panel 11, an inner wing panel 12, a second connecting panel 13, and a third connecting panel 14. The second connecting panel 13 is bent and connected to the outer wing panel 11 at both ends. The inner wing panel 12 is disposed on a side of the second connecting panel 13 and the outer wing panel 11 near the engine compartment, and together with the second connecting panel 13 and the third connecting panel 14, forms a receiving cavity 17. The third connecting panel 14 is spaced apart from the second connecting panel 13 and is connected to the outer wing panel 11. The outer wing panel 11, the inner wing panel 12, the second connecting panel 13, and the third connecting panel 14 enclose a receiving cavity 17. The outer wing panel 11, the inner wing panel 12, the second connecting panel 13, and the third connecting panel 14 respectively enclose two receiving cavities 17, effectively improving the structural strength of the wing box 10 while increasing the available space of the wing box 10.

The limit plate 50 is provided to limit the position of the battery 30. The heat dissipation hole 51 on the limit plate 50 not only meets the limit function but also saves material and provides good conditions for heat dissipation from the battery 30.

[0052] For details, please refer to Figure 3 The upper portion of the limit plate 50 is detachably connected to the inner wing plate 12 by bolts to facilitate replacement or maintenance of the battery 30.

[0053] It should be noted that the battery 30 generates heat during operation. Excessively high temperature will affect the performance of the battery 30 . Therefore, a heat dissipation hole 51 is provided on the limiting plate 50 to facilitate heat dissipation of the battery 30 and ensure normal use of the battery 30 .

[0054] Furthermore, while ensuring the structural strength of the limiting plate 50 , the number of the heat dissipation holes 51 can be increased according to actual conditions.

[0061] In one embodiment, Figure 4 As shown, the first connecting plate 21 includes a main plate 211 and a protective plate 212. The main plate 211 is connected to the protective plate 212. The main plate 211 has a notch, and the protective plate 212 covers the notch and protrudes toward the engine compartment. The protective plate 212 protrudes toward the engine compartment, and its front side provides space for the air conditioner and separates the rear engine compartment from the front cab.

[0062] Specifically, the protective plate 212 is protruded toward the engine compartment to form a mounting cavity, which is convenient for mounting the air conditioning structure.

[0063] It is worth noting that the main plate 211 and the protective plate 212 are separately provided, so as to adapt to different types of air-conditioning structures and improve the applicability of the first connecting plate 21 .

[0064] It should be noted that the main body panel 211 and the protective panel 212 can also be integrally formed, and a portion of the structure of the main body panel 211 is stamped toward the engine compartment to form the protective panel 212.

[0065] In one embodiment, Figure 4As shown, the first connecting plate 21 further includes a sound-absorbing and heat-insulating material 213, which is adhered to the protective plate 212. By providing the sound-absorbing and heat-insulating material 213, the noise and heat from the engine compartment can be effectively reduced from diffusing into the cab, thereby improving driving comfort.

[0066] For details, please refer to Figure 4 A plurality of sound-absorbing and heat-insulating materials 213 are provided to improve the sound-absorbing and heat-insulating effects.

[0067] Specifically, the sound-absorbing and heat-insulating material 213 is sound-absorbing and heat-insulating cotton.

[0068] Of course, in other alternative embodiments, the sound-absorbing and heat-insulating material 213 may also be sound-absorbing and heat-insulating cloth, synthetic fiber, etc.
