Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to a mounting bracket for a forklift power management component. Background Art
[0002] With growing environmental awareness and the shift in energy consumption, traditional internal combustion forklifts, due to their high emissions and energy consumption, are increasingly unable to adapt to current green and low-carbon development requirements. Therefore, heavy-duty electric forklifts, as a prominent representative of new energy technologies, have rapidly gained a foothold in industries such as warehousing and logistics, and port transportation, thanks to their zero emissions, low noise, and high efficiency. Electric forklifts are powered by batteries. Their power management components primarily consist of a high-voltage power distribution unit (PDU) and a DC-DC converter. The PDU connects to the power battery and distributes the DC power output to the forklift's various high-voltage electrical components, such as the charger, DC-DC converter, air conditioner, and PTC heater. The DC-DC converter converts the high-voltage power from the power battery into a low-voltage voltage suitable for the vehicle's low-voltage electronic devices (such as controllers, relays, and alarms), ensuring the proper functioning of the forklift's various low-voltage components.
[0003] However, while pursuing high efficiency and environmental performance for heavy-duty electric forklifts, achieving a compact internal structure presents a pressing technical challenge. Currently, due to this compactness requirement, the high-voltage distribution box and DC-DC converter are separately mounted on the right-hand bracket of the vehicle body. This layout not only places the high-voltage distribution box and DC-DC converter far from the operator center or power battery, but also results in longer high-voltage wiring, increasing energy consumption and safety risks. It also limits the effective use of the vehicle's interior space, impacting the overall aesthetics and practicality of the layout. Utility Model Content
[0004] The purpose of the utility model is to provide a mounting bracket for a forklift power management component, which can stack and install a high-voltage distribution box and a DC-DC converter together, effectively improving the utilization rate of the vehicle's interior space, and is easy to disassemble and assemble, and convenient for daily maintenance.
[0005] The specific technical solutions of the utility model are as follows:
[0006] A mounting frame for a forklift power management component includes a base frame and an upper bracket. The upper bracket is mounted on the top of the base frame and forms a receiving cavity for mounting a DC-DC converter. The top surface of the upper bracket is used to mount a high-voltage distribution box. Both ends of the base frame are respectively connected to connecting plates for connecting to the forklift frame.
[0007] In a further solution, the base frame includes symmetrically arranged support plates, two mounting plates are connected between the two support plates, and the top surfaces and outer side walls of the mounting plates are provided with mounting holes.
[0008] In a further solution, a middle support column is connected between the two mounting plates, and the support plate is an L-shaped structure, and a wire fixing plate is installed on the outer side wall of the vertical section.
[0009] In a further solution, the upper bracket includes a support frame, side frames are symmetrically and vertically fixed on both sides of the support frame, and the bottom ends of the side frames are fixedly connected to the top ends of the base frame.
[0010] In a further solution, waist-shaped threaded holes and weight-reducing holes are provided on the side frame.
[0011] The mounting frame of the utility model is composed of a stacked bottom frame and an upper bracket, and the DC-DC converter and the high-voltage distribution box are stacked on the mounting frame, which greatly saves installation space.
[0012] In addition, the cavity between the chassis and the upper bracket has ample space reserved for heat dissipation, such as the weight-reducing holes on the side frame and the gap between the two angle steels. This fully utilizes the upper space of the vehicle body while ensuring the heat dissipation requirements of the DC-DC converter.
[0013] Finally, the mounting bracket is easy to install and remove, making it convenient for daily maintenance. To install or remove it, simply remove the connectors between the left and right support plates on the bottom frame and the left and right connecting plates; or remove the connectors between the side frames of the upper bracket and the two angle steels of the bottom frame.

[0023] See Figure 1-4 This embodiment provides a mounting frame for a forklift power management component, including a base frame 3 and an upper bracket 4. The upper bracket 4 is mounted on the top of the base frame 3 and forms a receiving cavity for mounting a DC-DC converter 2; the top surface of the upper bracket 4 is used to mount a high-voltage distribution box 1; and both ends of the base frame 3 are respectively connected to connecting plates for connecting to a forklift frame.
[0024] In this embodiment, the base frame 3 is connected to a left connecting plate 5 and a right connecting plate 6 at each end. The base frame 3 is completely symmetrical, and the left and right connecting plates 5 and 6 are also symmetrical, thus preventing misalignment. The left and right connecting plates 5 and 6 are then fixedly connected to the frame of the electric forklift using bolts and other fasteners to complete the installation of the mounting bracket.
[0025] like Figure 2 The base frame 3 includes symmetrically arranged support plates 31 , two mounting plates are connected between the two support plates 31 , and mounting holes are formed on the top surfaces and outer side walls of the mounting plates.
[0026] like Figure 3 As shown, the upper bracket 4 includes a support frame 42 , and side frames 41 are symmetrically and vertically fixed on both sides of the support frame 42 , and the bottom ends of the side frames 41 are fixedly connected to the top ends of the bottom frame 3 .
[0027] In this embodiment, the mounting plate can be an angle steel 32 with mounting holes on both sides. Specifically, the mounting holes on the outer side of the angle steel 32 are fixedly connected to the side frame 41 of the upper bracket 4 via bolts. A receiving cavity is formed between the upper bracket 4 and the top surface of the bottom frame 3 for accommodating the DC-DC converter 2. The mounting holes on the top side of the angle steel 32 are connected to the DC-DC converter 2 via bolts, thereby achieving fixed installation of the DC-DC converter 2. The support frame 42 also has mounting holes, and the high-voltage distribution box 1 is placed on the support frame 42 and installed via bolts.
[0028] In another embodiment, a central support column 33 is connected between the two mounting plates to enhance the overall strength of the chassis 3. The support plate 31 is an L-shaped structure, and a cable fixing plate 34 is mounted on the outer side wall of the vertical section. The cable fixing plate 34 is used to fix the power cables of the DC-DC converter 2 and the high-voltage distribution box 1.
[0029] The side frame 41 is provided with waist-shaped threaded holes and weight-reducing holes. When the waist-shaped threaded holes are connected to the base frame 3, the size of the accommodating cavity can be adjusted to accommodate DC-DC converters 2 of different sizes. The weight-reducing holes are used for heat dissipation while reducing weight.
[0030] After the mounting frame of the utility model is assembled with the DC-DC converter 2 and the high-voltage distribution box 1, Figure 4 As shown, the overall size is compact, occupying a small space. The mounting frame of the present invention utilizes a stacked base frame 3 and upper frame 4 to stack the DC-DC converter 2 and high-voltage distribution box 1 on the mounting frame, significantly saving installation space. Furthermore, the cavity between the base frame and upper frame provides ample space for heat dissipation, such as the weight-reducing holes in the side frame 41 and the gap between the two angle steels 32. This fully utilizes the upper space of the vehicle body while ensuring the heat dissipation requirements of the DC-DC converter 2.
[0031] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application are within the scope of protection of the pending claims of the present application.
