[0030] like Figures 1 to 4 As shown, this utility model addresses the problem of unstable connection between the cover plate and the side door frame by providing a vehicle cover plate fixing structure, comprising:

[0031] Cover plate 1, one end of which is fixed to oil tank 2, and the other end of which is connected to the first end 31 of connecting bracket 3;

[0032] Side door frame 4, the connecting end 41 of the side door frame 4 is connected to the second end 32 of the connecting bracket 3 by bolts 5;

[0033] The second end 32 of the connecting bracket 3 includes a top plate 33 and a bottom plate 34 arranged opposite to each other, and a support plate 35 connecting the top plate 33 and the bottom plate 34. A plurality of studs 6 are spaced apart on the upper surface of the bottom plate 34. The plane at the top of the studs 6 forms an accommodating space with the top plate 33. The connecting end 41 of the side door frame 4 is engaged in the accommodating space.

[0034] In this embodiment of the present invention, a vehicle cover fixing structure is provided, including a cover plate 1, a fuel tank 2, a side door frame 4 and a connecting bracket 3. One end of the cover plate 1 is fixed to the fuel tank 2, and the other end of the cover plate 1 is connected to the side door frame 4 through the connecting bracket 3. The connecting bracket 3 and the side door frame 4 are fixed together by bolts 5. To enhance the stability of the connection between the cover plate 1 and the side door frame 4, i.e., the stability of the connecting bracket 3, multiple studs 6 are provided at the second end 32 of the connecting bracket 3 for connecting with the side door frame 4. Specifically, the second end 32 of the connecting bracket 3 includes a top plate 33 and a bottom plate 34 arranged opposite to each other, and a support plate 35 connecting the top plate 33 and the bottom plate 34. Multiple studs 6 are spaced apart on the upper surface of the bottom plate 34. The plane at the top of the stud 6 forms an accommodating space with the top plate 33, and the connecting end 41 of the side door frame 4 is engaged in this accommodating space. The side door frame 4 and the studs 6 fit tightly together, so that there are no gaps at the connection between the side door frame 4 and the connecting bracket 3, making the connection more stable. When the excavator is working, the studs 6 provide force support for the connecting bracket 3, and the vibration of the cover plate 1 will not cause the connecting bracket 3 to deform or crack, thus making the connection between the side door frame 4 and the cover plate 1 more stable.

[0035] Optionally, the top plate 33 of the connecting bracket 3 is provided with a plurality of first positioning holes 30;

[0036] The connecting end 41 of the side door frame 4 is provided with a plurality of second positioning holes;

[0037] The first positioning hole 30 and the second positioning hole correspond one-to-one, and the vertical center lines of the first positioning hole 30 and the second positioning hole coincide.

[0038] In this embodiment of the utility model, after the connecting end 41 of the side door frame 4 is engaged in the accommodating space of the connecting bracket, the multiple first positioning holes 30 provided on the top plate 33 correspond one-to-one with the multiple second positioning holes provided on the connecting end 41 of the side door frame 4, and the vertical center lines of the first positioning holes 30 and the second positioning holes coincide, which facilitates assembly.

[0039] Optionally, the bolt 5 passes through the corresponding first positioning hole 30 and second positioning hole in sequence, and the bolt 5 presses against the stud 6.

[0040] In this embodiment of the invention, after the connecting end 41 of the side door frame 4 is engaged in the accommodating space of the connecting bracket, the first section of the side door frame 4 and the top plate 33 of the connecting bracket 3 are fixedly connected. Specifically, the connection is achieved by sequentially inserting bolts 5 through the corresponding first positioning holes 30 and second positioning holes until the bolts 5 press against the upper surface of the studs 6. The bolts 5 fix the side door frame 4 and the connecting bracket 3 together, and the bolts 5 and the studs 6 press against each other, so that there are no gaps between the side door frame 4 and the connecting bracket 3, making the connection more stable. When the excavator is working, the vibration of the cover plate 1 will not cause the connecting bracket 3 to deform or crack, thus making the connection between the side door frame 4 and the cover plate 1 more stable.

[0041] Optionally, the stud 6 and the first positioning hole 30 are provided in a one-to-one correspondence, and the vertical center lines of the stud 6 and the first positioning hole 30 coincide.

[0042] In this embodiment of the invention, the studs 6 on the base plate 34 of the connecting bracket 3 and the first positioning holes 30 on the top plate 33 of the connecting bracket 3 are arranged in a one-to-one correspondence, that is, the studs 6 are directly below the first positioning holes 30. When the bolt passes through the first positioning hole 30, it can press against the studs 6, resulting in better stability.

[0043] Optionally, the stud 6 is welded onto the base plate 34;

[0044] In this embodiment of the invention, the stud 6 is welded to the base plate 34, making it less prone to loosening and more stable.

[0045] Optionally, a plurality of triangular plates 7 are spaced apart on the upper surface of the base plate 34, and the height of the triangular plates 7 is the same as the height of the stud 6.

[0046] In this embodiment of the utility model, in order to enhance the stability of the connecting bracket 3, a plurality of triangular plates 7 are also provided at intervals on the upper surface of the base plate 34 of the connecting bracket 3, and the height of the triangular plates 7 is the same as the height of the stud 6, that is, the plane at the top of the triangular plate 7 coincides with the plane at the top of the stud 6.

[0047] Furthermore, generally, the number of triangular plates 7 corresponds to the number of studs 6, with one triangular plate 7 provided on one side of each stud 6. It should be noted that the above structure is only used as an example and this utility model does not limit it.

[0048] Optionally, one end of the cover plate 1 is fixed to the oil tank 2 by welding.

[0049] In this embodiment of the utility model, the cover plate 1 and the oil tank 2 are connected by welding, which provides strong stability.

[0050] Optionally, the other end of the cover plate 1 is connected to the first end 31 of the connecting bracket 3 by welding.

[0051] In this embodiment of the invention, the cover plate 1 and the connecting bracket 3 are connected by welding, resulting in strong stability. Therefore, to achieve strong stability between the cover plate 1 and the side door frame 4, it is necessary to ensure strong stability between the connecting bracket 3 and the side door frame 4, as well as high strength of the connecting bracket 3. The connection method between the connecting bracket 3 and the side door frame 4 in the above embodiment of the invention effectively achieves both of these points.
