Description

[0001] The invention relates to a forklift truck, in particular a counterbalance forklift truck, with a vehicle body, wherein the forklift truck is provided with electrical and / or electronic components which are attached to a holder which is attached to the vehicle body.

[0002] In industrial trucks, especially counterbalance forklifts, it is known to arrange electrical and / or electronic components on a multi-part sheet metal holder that is attached to the vehicle body.

[0003] The disadvantage here is that the multi-part sheet metal holder involves a high degree of construction effort with high manufacturing costs and causes a high assembly effort for the mounting of the electrical and / or electronic components during the manufacture of the industrial truck.

[0004] The present invention is based on the objective of providing a forklift truck of the aforementioned type in which the construction effort for the holder is reduced and the assembly of the electrical and / or electronic components is simplified.

[0005] This problem is solved according to the invention by designing the holder as a one-piece plastic component which is provided with a mounting interface by means of which the plastic component can be attached to the vehicle body, and which is provided with mounting interfaces on which the electrical and / or electronic components can be attached, wherein the plastic component is provided with current-carrying contact pins on which electrical connecting cables can be attached.

[0006] A holder designed as a one-piece plastic component requires less manufacturing effort compared to a multi-part sheet metal holder. Furthermore, electrical and / or electronic components can be mounted on a one-piece plastic holder with reduced assembly effort. Another advantage of a one-piece plastic holder lies in the electrical insulating properties of the plastic material, which allows the current-carrying contact pins to be easily positioned on the plastic component without the need for additional insulators.Furthermore, a holder designed as a one-piece plastic component has the additional advantage that, due to its high damping properties, the plastic component enables low-vibration mounting of the electrical and / or electronic components to the vehicle body, thereby easily reducing the risk of failure and / or damage to the electrical and / or electronic components.

[0007] According to an advantageous embodiment of the invention, the plastic component is designed as an injection-molded part, and the current-carrying contact pins are injected into the injection-molded part. This allows the current-carrying contact pins to be formed and attached to the plastic component in a simple manner without additional insulators.

[0008] According to an advantageous embodiment of the invention, one or more of the following electrical and / or electronic components are attached to the plastic component: a contactor, a fuse box with fuses, an electrical resistor, a relay, a wiring harness comprising the electrical connecting cables.

[0009] This allows the essential electrical and / or electronic components of the industrial truck to be easily mounted on the holder, which is designed as a plastic component, and attached to the vehicle body of the industrial truck via the holder.

[0010] According to an advantageous embodiment of the invention, at least one of the fastening interfaces is designed as a screw connection.

[0011] Screw connections allow for easy mounting and fastening of the corresponding electrical and / or electronic components to the plastic component. The fastening interface can be designed as a receiving hole for a fastening screw formed in the plastic component, or as a fastening nut or screw injected into the plastic component.

[0012] According to an advantageous embodiment of the invention, at least one of the mounting interfaces is designed as a clip connection. The clip connection can be formed by spring pins on the plastic component, which hold the corresponding electrical and / or electronic components in a force-fit and / or form-fit manner. A clip connection enables simple, quick, and tool-free mounting of the corresponding electrical and / or electronic components to the plastic component.

[0013] According to an advantageous embodiment of the invention, the plastic component is provided with at least one slotted receiving recess into which the cable harness can be inserted. This allows the cable harness leading to the electrical and / or electronic components to be easily routed and secured to the plastic component.

[0014] According to an advantageous embodiment of the invention, the plastic component has two laterally spaced flange plates, each with at least one mounting interface for an electrical and / or electronic component. At least one stiffening rib is formed between the two flange plates, on which the receiving recesses are formed. This results in a space-saving mounting of the electrical and / or electronic components to the two flange plates, and the cable harness leading to the electrical and / or electronic components can be routed between the two flange plates in a space-saving manner and with short cable lengths.

[0015] According to an advantageous embodiment of the invention, the mounting interface is designed as a screw connection. A screw connection allows for simple and quick assembly and fastening of the plastic component to the vehicle body. The fastening interface can be designed as a receiving bore for a fastening screw formed in the plastic component, or as a fastening nut or screw injected into the plastic component.

[0016] According to an advantageous embodiment of the invention, the plastic component provided with the electrical and / or electronic components is designed as a pre-assembled module that can be attached to the vehicle body during the assembly of the industrial truck. Designing the plastic component with the attached electrical and / or electronic components as a pre-assembled module offers particular advantages, since the assembly of the electrical and / or electronic components onto the plastic component can be carried out outside the industrial truck and independently of the cycle times on the industrial truck's assembly line, thus achieving savings in the production of the industrial truck.

[0017] Further advantages and details of the invention are explained in more detail with reference to the exemplary embodiment shown in the schematic figures.
