Description

Technical Field

[0001] The utility model relates to a prototype debugging protection device, in particular to a prototype debugging graded protection device for a three-electric system of a walking chassis of an agricultural robot. Background Art

[0002] The chassis of agricultural robots is different from that of ordinary new energy vehicles. Ordinary new energy vehicles mostly travel on paved roads, and the drive motors are mostly single or dual motors, generally not more than 4 motors, and the motor power does not differ much. Although the chassis of agricultural robots also uses batteries to provide energy sources and uses motors to convert electrical energy into mechanical energy, agricultural robots need to operate in dry fields, hills, rice fields, mountains, facility farms and other environments. The chassis needs to adapt to 2.5D undulating terrain, and the chassis needs to adjust the wheelbase according to the planting row spacing of different crops. The above working conditions require that agricultural chassis mostly adopt multi-wheel drive, and multiple motors adjust the chassis wheelbase and wheelbase.

[0003] For example, an agricultural robot chassis has four wheel hub motors, four steering motors, and four variable track motors, for a total of 12 main motors. Based on power design requirements, the wheel hub motors have higher power than the steering and variable track motors. Furthermore, the chassis power battery is equipped with a power supply module for the upper layer, which consumes power. The power battery only provides a single voltage range (i.e., the battery voltage at the current SOC), which translates into different current requirements for different power requirements.

[0004] When designing and developing prototypes, there are many uncertainties (such as the risk of improper component selection, the risk of mechanical mismatch during initial assembly, and the risk of incorrect initial circuit structure). External fuses are often used to protect the prototype. As the development process progresses and the calibration parameters mature, performance parameters are gradually adjusted and relaxed, and the fuses used in the development phase are ultimately removed. When debugging different functions and performance, the upper limit of the chassis current demand varies greatly. Multiple replacements of fuses of different specifications require shutting down the machine, powering off, replacing the fuse, and preparing for powering on, which is time-consuming and labor-intensive. Furthermore, repeated disassembly and assembly can easily lead to installation errors, short circuits, and excessive heat and fire caused by excessive resistance in the virtual connection.

[0022] The technical effects of the utility model are:

[0023] During the debugging stage of the prototype of the walking chassis of the agricultural robot, the general protection device is a single fuse or multiple fuses that need to be manually wired to adjust the specifications (levels), which is inefficient and prone to wiring errors.

[0039] See also Figures 1-4 , Figure 1 This is a structural diagram of an embodiment of the present utility model. Figure 2 This is a front view of an embodiment of the utility model. Figure 3 for Figure 2 A top view of Figure 4 for Figure 2 The prototype debugging graded protection device for the three-electric system of the walking chassis of an agricultural robot of the present invention comprises: a housing 1; an insulating base, mounted in the housing 1 and located on the bottom surface of the housing 1; a busbar 4, mounted on the insulating base, preferably a busbar; a selection switch 6, provided on the housing 1, the selection switch 6 can be a knob switch or a push-button switch, preferably a knob switch; a plurality of fuses 5, respectively mounted on the insulating base; each of the fuses 5 has different specifications; one end of each of the fuses 5 is connected to the busbar 4, and the other end of each of the fuses 5 is connected to the selection switch 6; and terminals 7, respectively connected to the busbar 4 and the selection switch 6.

[0040] In this embodiment, an upper cover 2 is also included, and the upper cover 2 is snapped with the shell 1 through a sub-opening. The upper cover 2 is preferably made of a transparent material, and it is possible to directly observe whether the fuse 5 is in a normal state and whether the wiring circuit is normal through the transparent upper cover 2. An insulating sleeve 8 may also be included, which is installed between the shell 1 and the terminal 7. The terminal 7 includes a first terminal 7 and a second terminal 7. The first terminal 7 and the second terminal 7 are arranged side by side on one side of the shell 1. The first terminal 7 is connected to the selection switch 6, and the second terminal 7 is connected to the bus 4.

The first terminal 7 is connected to the selection switch 6 through a first cable, and the second terminal 7 is connected to the bus 4 through a second cable.

[0041] In this embodiment, the multiple fuses 5 are six fuses 5 with specifications of 20A, 40A, 60A, 100A, 250A, and 500A, respectively, at an 80V voltage level. Each of the fuses 5 is connected to the busbar 4 and the selector switch 6 via cables. The upper cover 2 and the housing 1 are positioned and snapped together via a sub-opening. When replacing internal fuses 5, the upper cover 2 can be opened for replacement. The internal fuses 5 are connected to the busbar 4 via bolts, and the other end of each fuse 5 is connected to the gear selector switch 6 via a cable. Bolts secure the fuses 5 to the insulating base plate 3, which insulates the internal circuit from the housing 1 and the upper cover 2.
