Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a wiring harness arrangement structure for a forklift battery and a forklift. Background Technology

[0002] A high-voltage lithium battery forklift is an electric forklift that uses high-efficiency lithium batteries as its power source. It typically consists of multiple lithium battery packs packaged together and fixed to the forklift body. In addition, high-voltage lithium battery forklifts are often equipped with cooling systems, fire protection systems, and power distribution systems (i.e., power management systems) to assist the normal operation of the battery packs.

[0003] The various systems of the high-voltage lithium battery forklift are scattered in different installation locations of the vehicle, and each system needs to be connected to the battery pack and the vehicle. That is, each system, battery pack and vehicle are connected to each other through their own wiring harnesses and connectors, which makes the connection points relatively scattered and the wiring complex.

[0004] To remove or replace the battery pack, each connector must be disconnected before the battery pack can be removed or replaced. This process of removing and replacing the battery pack is tedious and complicated. In the process of removing and replacing the battery pack, some connectors may be missed, and the wiring harness may be pulled or damaged. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a wiring harness arrangement structure for a forklift battery and a forklift, which connects the wiring harnesses of the battery pack assembly to the same wiring harness connector to avoid missing connectors and damage to wiring harnesses during battery pack assembly and disassembly.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] This utility model provides a wiring harness arrangement structure for a forklift battery, including a wiring harness connector, a bracket, and a battery pack assembly mounted on the bracket; the output ends of each wiring harness of the battery pack assembly are electrically connected to the input ends of the wiring harness connector.

[0008] Furthermore, the battery pack assembly includes at least a battery pack, a power management system, a cooling system, and a fire suppression system, with the output terminals of the wiring harnesses of the battery pack, the power management system, the cooling system, and the fire suppression system respectively electrically connected to the input terminals of the wiring harness connectors.

[0009] Furthermore, the bracket includes a base and a mounting bracket mounted on the base. The mounting bracket has multiple mounting slots arranged vertically. The battery pack has multiple battery groups, each of which is mounted in a corresponding mounting slot.

[0010] Furthermore, the projected area of ​​the mounting bracket is smaller than the projected area of ​​the base; the mounting bracket is located on one side of the base, and the power management system, the cooling system, and the fire protection system are respectively located on the other side of the base away from the mounting bracket.

[0011] Furthermore, the cooling system is assembled to the base via a connector, and the power management system is located at the end of the cooling system opposite to the base; the fire protection system is assembled to the base via a connecting bracket.

[0012] Furthermore, a main wire harness tube is provided between the battery pack assembly and the wire harness connector. The output ends of the wire harnesses of the battery pack assembly are respectively passed through the main wire harness tube and electrically connected to the input ends of the wire harness connector.

[0013] Furthermore, the main wire harness tube is disposed on the bracket.

[0014] This utility model provides a forklift, including a forklift body and the aforementioned wiring harness arrangement structure for the forklift battery; the wiring harness arrangement structure for the forklift battery is assembled to the forklift body.

[0015] Furthermore, the wiring harness arrangement of the forklift battery is detachably assembled to the forklift body.

[0016] Furthermore, the wiring harness of the forklift battery is screwed to the forklift body.

[0017] The technical solution provided by this utility model has the following beneficial effects:

[0018] By mounting the battery pack assembly on the bracket and electrically connecting the output ends of each wiring harness of the battery pack assembly to the input ends of the wiring harness connector, an independent bracket assembly is formed. This also allows the wiring harnesses of the battery pack assembly to be electrically connected to the same wiring harness connector, and then connected to the vehicle's signal connector through the wiring harness connector. This enables centralized connection between multiple systems of the battery pack assembly and the vehicle, thereby simplifying wiring and preventing connectors from being missed or wiring harnesses from being pulled or damaged during the removal and installation of forklift batteries.

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 3 As shown, Embodiment 1 provides a wiring harness arrangement structure for a forklift battery (hereinafter referred to as the wiring harness arrangement structure) to simplify the disassembly and assembly of the forklift battery during maintenance, upkeep and repair.

[0026] like Figure 1 As shown, the wiring harness arrangement structure of this embodiment includes a wiring harness connector 1, a bracket 2, and a battery pack assembly 3 disposed on the bracket 2, and the output terminals of each wiring harness of the battery pack assembly 3 are electrically connected to the input terminals of the wiring harness connector 1.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the battery pack assembly 3 includes a battery pack 31, a power management system 32, a cooling system 33, and a fire protection system 34. Specifically, the battery pack 31 has three battery groups 311, and the output terminals of the wiring harnesses of the battery pack 31, the power management system 32, the cooling system 33, and the fire protection system 34 are electrically connected to the input terminals of the wiring harness connector 1, so as to realize the electrical connection of each wiring harness of the battery pack assembly 3 to the same wiring harness connector 1.

[0028] Of course, in other embodiments, the battery pack assembly 3 may also include other systems such as a sensor system. Furthermore, the battery pack 31 may also have one or more battery cells 311.

[0029] When maintenance or removal of the forklift battery is required, simply disconnect the wiring harness connector 1 and remove the bracket 2 from the vehicle. Therefore, by loosening only one wiring harness connector 1, the connection between the vehicle, battery pack 31, power management system 32, cooling system 33, and fire suppression system 34 can be directly disconnected. This eliminates the need to remove multiple connection points on the forklift, ensuring that all electrical connections are correctly disconnected when the forklift battery is removed, reducing the risk of wiring harness damage, simplifying the disassembly and assembly process, preventing missed connectors, and avoiding pulling on the wiring harness. This also significantly reduces the time required for forklift battery removal and maintenance.

[0030] More specifically, such as Figure 3 As shown, the bracket 2 includes a base 21 and a mounting bracket 22 mounted on the base 21. The mounting bracket 22 has two mounting slots 221 arranged vertically, such as... Figure 1 As shown, two battery packs 311 are respectively mounted in their corresponding mounting slots 221, and a third battery pack 311 is mounted on the top wall of the upper mounting slot 221. Of course, in other embodiments, the mounting bracket 22 can also use a sliding rail and a snap-fit ​​structure to fix each battery pack 311 in place. Furthermore, the number of mounting slots 221 depends on the number of battery packs 311.

[0031] In addition, the projected area of ​​the mounting bracket 22 is smaller than that of the base 21 to ensure sufficient installation space. When the mounting bracket 22 is located on one side of the base 21, the power management system 32, cooling system 33 and fire protection system 34 are respectively located on the other side of the base 21 away from the mounting bracket 22. That is, the power management system 32, cooling system 33 and fire protection system 34 can be installed in the installation space. This also ensures that the battery pack 31, power management system 32, cooling system 33 and fire protection system 34 are installed in a relatively compact, reasonable and orderly manner on the bracket 2.

[0032] In specific implementation, such as Figure 1 As shown, the cooling system 33 is mounted on the base 21 via the connector 5, and the power management system 32 is located at the top of the cooling system 33 away from the base 21. The fire protection system 34 is mounted on the base 21 via the connector 6.

[0033] like Figure 1 and Figure 2 As shown, a main wire harness tube 4 is provided between the battery pack assembly 3 and the wire harness connector 1. The main wire harness tube 4 is located on the inner side of the mounting bracket 22 near the power management system 32. The output ends of the wire harnesses of the battery pack 31, power management system 32, cooling system 33 and fire protection system 34 are respectively passed through the main wire harness tube 4 and electrically connected to the input end of the wire harness connector 1, so as to concentrate the various dispersed wire harnesses in the main wire harness tube 4.

[0034] By mounting the battery pack assembly 3 on the bracket 2 and electrically connecting the output ends of each wiring harness of the battery pack assembly 3 to the input ends of the wiring harness connector 1, an independent bracket 2 assembly is formed. This also enables the electrical connection of each wiring harness of the battery pack assembly 3 to the same wiring harness connector 1. The wiring harness connector 1 is then connected to the vehicle's signal connector, achieving centralized connection between multiple systems of the battery pack assembly 3 and the vehicle. This simplifies wiring and prevents connectors from being missed during the removal and installation of forklift batteries, as well as prevents wiring harnesses from being pulled or damaged.

[0036] Embodiment 2 provides a forklift, including a forklift body and a wiring harness arrangement structure for the forklift battery as described in Embodiment 1, wherein the wiring harness arrangement structure for the forklift battery is assembled to the forklift body.

[0037] In this embodiment, the wiring harness arrangement structure of the forklift battery is detachably assembled to the forklift body, and the wiring harness arrangement structure of the forklift battery is screwed to the forklift body by nuts and bolts.

[0038] Of course, in other embodiments, the wiring harness arrangement structure of the forklift battery can also be snapped onto the forklift body through slide rails, slide grooves, and snap-fit ​​structures.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
