[0033] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0034] Next, reference will be made to Figures 1-6 describe the frame assembly 100 according to the embodiment of the first aspect of the present utility model.

[0035] As Figure 1 and Figure 2 shown, the frame assembly 100 according to the embodiment of the first aspect of the present utility model includes: a frame 10 and a counterweight 20.

[0036] Specifically, the frame 10 includes a frame main body 11 and a support frame 12. The support frame 12 is connected to the rear end of the frame main body 11 and extends rearward. The counterweight 20 is fixed to the support frame 12. The front end of the counterweight 20 is provided with a first balance portion 21 and a second balance portion 22. The first balance portion 21 and the second balance portion 22 extend vertically and are arranged at intervals left and right. The first balance portion 21 and the second balance portion 22 are respectively located on the left and right sides of the support frame 12, and the first balance portion 21 and the second balance portion 22 extend downward at least to the lower part of the frame main body 11.

[0037] Wherein, the first balance portion 21 and the second balance portion 22 may extend to the lower area of the frame main body 11, and the first balance portion 21 and the second balance portion 22 may also extend to be flush with the lower side edge of the frame main body 11.

[0038] It can be understood that the counterweight 20 is relatively heavy and accounts for a relatively large proportion of the weight on the frame assembly 100. The second balance portion 22 and the second balance portion 22 extend downward at least to the lower part of the frame main body 11, which can increase the weight proportion of the lower area of the frame assembly 100. In this way, the center of gravity of the frame assembly 100 can be reduced, thereby improving the stability during the operation of the forklift.

[0039] At the same time, the second balance portion 22 and the second balance portion 22 are respectively located on the left and right sides of the support frame 12, which can make the weight distribution on the frame assembly 100 more uniform, thereby further improving the stability during the operation of the forklift.

[0040] During the assembly process, the first balance portion 21 and the second balance portion 22 can be positioned and limited on both sides of the support frame 12. In this way, when connecting the counterweight 20 and the support frame 12, the operation is relatively easy, which can reduce the assembly difficulty during the production process. And it can be understood by those skilled in the art that during the product design process, compared with adjusting the structural design of the vehicle frame main body 11, the difficulty of adjusting the structural design of the support frame 12 is lower. Therefore, during the product design process, by adjusting the matching relationship between the support frame 12 and the counterweight 20 to make the vehicle frame assembly 100 meet more product design requirements, the design difficulty of the forklift can be reduced.

[0041] The vehicle frame assembly 100 according to the first aspect embodiment of the present invention can reduce the center of gravity of the forklift, improve the stability during the operation of the forklift, and can reduce the assembly difficulty and design difficulty of the forklift.

[0042] In some embodiments of the present invention, such as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, the counterweight 20 further includes: a mounting plate portion 23, the mounting plate portion 23 is a horizontal plate, the first balance portion 21 and the second balance portion 22 are connected to the front end of the mounting plate portion 23, and the mounting plate portion 23 is fixedly connected to the support frame 12. In this way, the matching relationship between the counterweight 20 and the support frame 12 is relatively simple. During the connection process between the mounting plate portion 23 and the support frame 12, it is easier to position the mounting plate portion 23 and the support frame 12, which can further reduce the production difficulty. At the same time, the weight proportion of the mounting plate portion 23 is relatively small, which can further reduce the center of gravity of the forklift.

[0043] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the mounting plate portion 23 is arranged on the upper side of the support frame 12. Thus, during the assembly process, the support frame 12 can support the counterweight 20, and it is easier for the operator to keep the counterweight 20 stationary during the assembly process, thereby further reducing the production difficulty.

[0044] In some embodiments of the present invention, such as Figures 3-6 shown, a first mounting hole 121 is formed on the upper side of the support frame 12, a second mounting hole 231 penetrating through the mounting plate portion 23 up and down is formed on the mounting plate portion 23, and the vehicle frame assembly 100 further includes: a first fastener 30, the first fastener 30 sequentially passes through the second mounting hole 231 and the first mounting hole 121 to fixedly connect the mounting plate portion 23 and the support frame 12.

[0045] During the assembly process, first place the mounting plate portion 23 of the counterweight 20 at the designated position on the support frame 12. In this way, the support frame 12 supports the mounting plate portion 23 from below. The operator sequentially passes the first fastener 30 through the second mounting hole 231 and the first mounting hole 121 in the up-and-down direction. The shear force between the first fastener 30 and the second mounting hole 231 and the first mounting hole 121 is small, and it is relatively easy for the first fastener 30 to pass through the second mounting hole 231 and the first mounting hole 121, which can further reduce the production difficulty.

[0046] Similarly, when it is necessary to disassemble the counterweight 20 from the support frame 12, when removing the first fastener 30 from the first mounting hole 121 and the second mounting hole 231, the shear force between the first fastener 30 and the second mounting hole 231 and the first mounting hole 121 is small, and it is relatively easy for the first fastener 30 to be removed from the second mounting hole 231 and the first mounting hole 121, which can reduce the disassembly difficulty.

[0047] Preferably, the first fastener 30 is a fastening bolt. The fastening bolt is convenient to operate and has a relatively high connection strength, which can improve the connection strength between the counterweight 20 and the support frame 12.

[0048] In some embodiments of the present invention, as Figure 1 、 Figure 2 and Figure 5 shown, the counterweight 20 further includes: a surrounding plate portion 24. The surrounding plate portion 24 is connected to the edge of the mounting plate portion 23 and extends upward. The surrounding plate portion 24 and the mounting plate portion 23 cooperate to define an upwardly open mounting space 241 for installing components. Thus, the space inside the counterweight 20 can be reasonably utilized, thereby further reducing the design difficulty of the forklift.

[0049] In some embodiments of the present invention, as Figure 1 、 Figure 2 and Figure 5 shown, the vehicle frame assembly 100 further includes: a component mounting plate 40. The component mounting plate 40 is used for installing components. The component mounting plate 40 is disposed in the mounting space 241. A third mounting hole is formed on the component mounting plate 40. The first fastener 30 sequentially passes through the third mounting hole, the second mounting hole 231 and the first mounting hole 121 to fix the component mounting plate 40 to the mounting plate portion 23. In this way, during the process of assembling the counterweight 20 to the support frame 12, the component mounting plate 40 can also be assembled to the counterweight 20 synchronously. On the one hand, the assembly efficiency can be improved. On the other hand, the second mounting hole 231 can be integrally formed during the production of the counterweight 20. When installing components, only the structure of the component mounting plate 40 needs to be changed. It can be understood that the processing cost of the component mounting plate 40 is lower than that of the counterweight 20, thereby reducing the production cost.

[0050] In some embodiments of the present utility model, as Figure 3 , Figure 5 and Figure 6 shown, support plates 122 are provided at both the front and rear ends of the support frame 12, first mounting holes 121 are formed on the support plates 122, and second mounting holes 231 are respectively formed at the front and rear ends of the mounting plate portion 23 and correspond to the first mounting holes 121 one by one.

[0051] In this way, after assembly, both the front and rear ends of the support frame 12 can fix the counterweight 20, thereby improving the reliability of the counterweight 20 on the support frame 12 and enhancing the stability of the counterweight 20 on the support frame 12. Among them, by providing the support plates 122, it is convenient to arrange the first mounting holes 121 on the support frame 12. Preferably, the support plate 122 located on the front side is connected to the rear end of the vehicle frame main body 11.

[0052] In some embodiments of the present utility model, the second mounting holes 231 are oblong holes extending in the front-rear direction or left-right direction. In this way, during the assembly process, it is easier to align the second mounting holes 231 with the first mounting holes 121, thereby further reducing the production difficulty.

[0053] In some embodiments of the present utility model, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, the vehicle frame assembly 100 further includes: a third balance portion 25, the third balance portion 25 is connected to the rear end of the mounting plate portion 23 and extends downward, and the first balance portion 21, the second balance portion 22, the third balance portion 25 and the mounting plate portion 23 cooperate to define a receiving space 26 for receiving the rear axle and the wheels, and the rear end of the support frame 12 is connected to the third balance portion 25.

[0054] In this way, the mounting plate portion 23 and the third balance portion 25 can block the muddy water splashed by the rear wheels, and during the production process, the counterweight 20 can be integrally formed, and the sealing performance between the mounting plate portion 23 and the first balance portion 21, the second balance portion 22, the third balance portion 25 is relatively high, which can improve the user experience.

[0055] In some embodiments of the present utility model, as Figure 3 and Figure 6 shown, a fourth mounting hole 123 extending in the front-rear direction is formed at the rear end of the support frame 12, a fifth mounting hole 251 extending in the front-rear direction is formed on the third balance portion 25, and the vehicle frame assembly 100 further includes: a second fastener 31, the second fastener 31 sequentially passes through the fourth mounting hole 123 and the fifth mounting hole 251 to connect the rear end of the support frame 12 to the third balance portion 25.

[0056] Thus, after the assembly is completed, the third balance portion 25 can fix the rear end of the support frame 12, thereby further improving the connection reliability between the counterweight 20 and the support frame 12 and enhancing the stability of the counterweight 20 on the support frame 12.

[0057] During the process of disassembling and assembling the counterweight 20 on the support frame 12, the support frame 12 supports the counterweight 20 on the lower side of the mounting plate portion 23. The second fastener 31 is less subjected to shear force when entering and exiting the fourth mounting hole 123 and the fifth mounting hole 251 in the front-rear direction, which can further reduce the difficulty of disassembling and assembling the counterweight 20 on the support frame 12.

[0058] In some embodiments of the present invention, such as Figure 3 and Figure 6 as shown, the rear end face of the support frame 12 extends vertically. The third balance portion 25 is provided with a rear end mounting plate 252, the rear end mounting plate 252 extends vertically, the fifth mounting hole 251 is formed in the rear end mounting plate 252 and penetrates the rear end mounting plate 252 in the front-rear direction. The rear end face of the support frame 12 is attached to the rear end mounting plate 252. In this way, during the assembly process, the rear end of the support frame 12 and the rear end mounting plate 252 can cooperate for positioning, thereby further reducing the production difficulty.

[0059] Preferably, a through hole 253 penetrating left and right is formed at the rear side of the rear end mounting plate 252, and the rear taillight is installed on the counterweight 20 through the through hole 253.

[0060] In some embodiments of the present invention, the fifth mounting hole 251 is an elongated hole extending in the front-rear direction or the left-right direction. In this way, during the assembly process, it is easier to align the fifth mounting hole 251 with the fourth mounting hole 123, thereby further reducing the production difficulty.

[0061] In some embodiments of the present invention, such as Figure 4 as shown, the vehicle frame assembly 100 further includes: a rear axle, and the rear axle is connected to the lower side of the support frame 12. Thus, the assembly space on the vehicle frame assembly 100 can be reasonably utilized, making the structure of the vehicle frame assembly 100 more compact. Preferably, a downwardly protruding axle mounting portion 124 is formed on the lower side of the support frame 12, and an axle mounting hole 1241 is formed in the axle mounting portion 124. The rear axle is installed on the lower side of the support frame 12 through the axle mounting hole 1241.

[0062] In some embodiments of the present invention, the vehicle frame assembly 100 further includes: a front vehicle frame 13, the front vehicle frame 13 is connected to the front end of the vehicle frame body 11, the front axle is connected to the front end of the front vehicle frame 13, and both the front vehicle frame 13 and the support frame 12 are welded to the vehicle frame body 11.
