Description

Technical Field

[0001] This utility model relates to the field of unmanned forklift technology, and in particular to a waterproof electrical control box for unmanned forklifts. Background Technology

[0002] With the rapid development of the logistics industry, unmanned forklifts have been widely used in warehousing and material handling. However, in special environments such as cold storage, the normal operation of unmanned forklifts faces severe challenges. Most existing unmanned forklifts are modified from forklifts used in ordinary scenarios, requiring the addition of numerous sensors to detect the external environment and their own operational status. The data collected by these sensors is connected to industrial control computers, power supplies, switches, and other electrical components via wiring harnesses. However, in special usage scenarios such as cold storage, where temperatures are low and humidity is high, the low temperature of the external environment causes moisture in the air to easily condense on the wire ends and surfaces of various electrical components. After prolonged operation in such low-temperature, high-humidity environments, condensation can cause short circuits, poor contact, and other problems, severely affecting the stability of the unmanned forklift control system and even leading to system failure. Currently, ordinary electrical control boxes lack effective waterproof structural designs and cannot withstand the intrusion of condensation in cold storage environments, making it difficult to meet the usage requirements of unmanned forklifts in this scenario. Therefore, designing an unmanned forklift electrical control box with good waterproof performance is particularly necessary. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof electrical control box for unmanned forklifts, addressing the problem in existing technologies where insufficient waterproofing of the electrical control box in low-temperature, high-humidity environments such as cold storage leads to condensation affecting wiring harnesses and electrical components, causing control system malfunctions. Through a rational structural design and the selection of waterproof components, effective protection of the electrical control system is achieved, improving the stability and reliability of the unmanned forklift in special environments.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A waterproof electrical control box for an unmanned forklift includes an unmanned forklift body, a mounting bracket, an electrical control box body, and electrical components. The mounting bracket is fixedly installed on the unmanned forklift body. The electrical control box body is mounted on the mounting bracket, and the electrical components are located inside the electrical control box body and connected to external wiring harnesses through waterproof interfaces on the electrical control box body. The electrical control box body includes an electrical control box body, an electrical control box door, a sponge strip, a latch, a waterproof power cable connector, a waterproof network cable connector, a waterproof HDMI adapter, and a waterproof USB adapter. The electrical control box body and the electrical control box door are connected by a latch, and a sponge strip is provided at the connection point. Both the edges of the electrical control box body and the electrical control box door adopt a right-angle flange design. The waterproof power cable connector, waterproof network cable connector, waterproof HDMI adapter, and waterproof USB adapter are all installed on the electrical control box body.

[0006] Furthermore, the electrical components are connected to the inner ends of the waterproof wire-to-plug, waterproof network cable-to-plug, waterproof HDMI adapter, and waterproof USB adapter via internal wiring harnesses, and the external sensors are connected to the outer ends of each waterproof interface via external wiring harnesses.

[0007] Furthermore, the main body of the electrical control box is detachably connected to the body of the unmanned forklift via a mounting bracket.

[0008] Furthermore, the sponge strip has a ring structure and is attached around the outer periphery of the right-angle flange of the electrical control box. When the electrical control box and the electrical control box door are locked together by the latch, the sponge strip is compressed between the right-angle flange of the electrical control box and the electrical control box door.

[0009] Furthermore, the mounting bracket is fixed to a preset position on the unmanned forklift vehicle body by welding or bolting.

[0010] Furthermore, the main body of the electrical control box is mounted on the mounting bracket by bolts.

[0011] Furthermore, the right-angle flange lengths of the electrical control box body and the electrical control box door are 20mm and 18mm, respectively.

[0012] Furthermore, the number of latches is two, symmetrically distributed on the left and right sides of the connection edge between the electrical control box and the electrical control box door.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Excellent waterproof performance. Through the right-angle flange design of the electrical control box body and door, the sealing of the ring-shaped sponge strip, and the locking effect of the symmetrically distributed buckles, a reliable airtight connection is formed, which can effectively prevent condensation water in the cold storage environment from entering the electrical control box, protecting electrical components and wiring harness ends from the influence of condensation water, and reducing the probability of faults such as short circuits and poor contact.

[0015] 2. Stable and reliable connection. Electrical components are connected to the inner ends of each waterproof interface via internal wiring harnesses, while external sensors are connected to the outer ends of each waterproof interface via external wiring harnesses. This connection method not only ensures the stability of signal transmission, but also ensures that each waterproof interface itself has good waterproof performance, further enhancing the overall waterproof effect of the electrical control box.

[0016] 3. Convenient installation and maintenance. The main body of the electrical control box is detachably connected to the unmanned forklift body via a mounting bracket. The main body of the electrical control box and the mounting bracket are connected by bolts. The mounting bracket and the unmanned forklift body can be fixed by welding or bolts. These designs make the installation, disassembly and maintenance of the electrical control box more convenient and faster, reducing the later maintenance costs.

[0017] 4. Reasonable structural design. The right-angle flange lengths of the electrical control box body and the electrical control box door are set to 20mm and 18mm respectively, and the number of latches is 2 and symmetrically distributed on the left and right. These detailed designs make the electrical control box structure compact and the stress evenly distributed, ensuring the overall stability and sealing. Attached Figure Description
