Description

Technical Field

[0001] This invention relates to a prototype debugging and protection device, and in particular to a graded protection device for the prototype debugging of the three-electric system of an agricultural robot chassis. Background Technology

[0002] Agricultural robot chassis differ from ordinary new energy vehicle chassis. Ordinary new energy vehicles mostly travel on paved roads, and their drive motors are mostly single or dual motors, generally not exceeding four motors, with little difference in motor power. Although agricultural robot chassis also use batteries to provide energy and utilize motors to convert electrical energy into mechanical energy, agricultural robots need to operate in environments such as dry fields, hills, paddy fields, mountains, and facility farms. The chassis needs to adapt to 2.5D undulating terrain, and the wheel track needs to be adjusted according to the planting row spacing of different crops. These working conditions require agricultural robot chassis to adopt multi-wheel drive and multiple motors to adjust the chassis wheel track and wheelbase.

[0003] For example, an agricultural robot chassis has four wheel hub motors, four steering motors, and four variable track motors, totaling 12 main motors. Based on power design requirements, the hub motors have higher power outputs than the steering and variable track motors. Simultaneously, the chassis's power battery includes modules that supply power to the upper layers. Since the power requirements vary, and the power battery only provides one voltage range (i.e., the power battery voltage at the current state of charge), different power demands are translated into different current requirements.

[0004] When designing and developing prototypes, there are many uncertainties (such as risks of improper component selection, mismatches in the initial assembly of mechanical mechanisms, and incorrect initial circuit structures). External fuses are often used to protect the prototypes. As the development process progresses and calibration parameters mature, performance parameters are gradually adjusted and relaxed, eventually removing the fuses from the development phase. When debugging different functions and performance levels, the upper limit of the chassis current requirement varies greatly. Changing fuses of different specifications multiple times requires stopping the machine, powering off, replacing the fuses, and preparing for power-on, which is time-consuming and labor-intensive. Furthermore, repeated disassembly and reassembly can easily lead to installation errors, operational short circuits, excessive resistance due to loose connections, and even overheating and fire risks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a graded protection device for debugging the prototype of the three-electric system of the walking chassis of an agricultural robot, which addresses the above-mentioned defects of the prior art.

[0006] To achieve the above objectives, the present invention provides a graded protection device for debugging the prototype of the three-electric system of an agricultural robot's walking chassis, comprising:

[0007] case;

[0008] An insulating base is installed inside the housing and located on the bottom surface of the housing;

[0009] Busbar, mounted on the insulating base;

[0010] A selection switch is located on the housing;

[0011] Multiple fuses are mounted on the insulating base; each fuse has a different specification; one end of each fuse is connected to the busbar, and the other end of each fuse is connected to the selector switch; and

[0012] The terminals are connected to the busbar and the selector switch, respectively.

[0015] The aforementioned agricultural robot chassis electric system prototype debugging and graded protection device also includes an insulating sleeve installed between the housing and the terminal block.

[0016] The above-mentioned prototype debugging and graded protection device for the three-electric system of the agricultural robot walking chassis includes a first terminal and a second terminal. The first terminal and the second terminal are arranged side by side on one side of the housing. The first terminal is connected to the selector switch, and the second terminal is connected to the busbar.

[0018] The above-mentioned agricultural robot walking chassis three-electric system prototype debugging graded protection device, wherein the first terminal is connected to the selector switch through the first cable, and the second terminal is connected to the busbar through the second cable.

[0019] The prototype of the above-mentioned agricultural robot chassis electric system has a graded protection device for debugging, wherein the multiple fuses are six fuses with specifications of 20A, 40A, 60A, 100A, 250A and 500A, respectively, with a voltage level of 80V.

[0021] The above-mentioned agricultural robot chassis electric system prototype debugging graded protection device includes multiple fuses connected to the busbar and the selector switch via cables.

[0022] The technical advantages of this invention are as follows:

[0023] During the debugging phase of the prototype of the agricultural robot chassis, the protection device is usually a single fuse or multiple fuses, which require manual wiring to adjust the specifications (levels). This is inefficient and prone to wiring errors. The present invention realizes the function of connecting and disconnecting fuses of different specifications and levels. It can quickly switch between multiple levels of fuses with one wiring, reducing the operation time of replacing different levels of fuses and avoiding the potential risks caused by multiple replacement operations.

[0038] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0039] See Figures 1-4 , Figure 1 This is a schematic diagram of a structure according to an embodiment of the present invention. Figure 2 This is a front view of an embodiment of the present invention. Figure 3 for Figure 2 Top view, Figure 4 for Figure 2 A side view. The prototype debugging and graded protection device for the three-electric system of the agricultural robot walking chassis of the present invention includes: a housing 1; an insulating base, installed inside the housing 1 and located on the bottom surface of the housing 1; a busbar 4, installed on the insulating base, preferably a copper busbar; a selector switch 6, disposed on the housing 1, the selector switch 6 can be a rotary switch or a push-button switch, preferably a rotary switch; a plurality of fuses 5, respectively installed on the insulating base; each fuse 5 has a different specification; one end of each fuse 5 is connected to the busbar 4, and the other end of each fuse 5 is connected to the selector switch 6; and terminals 7, respectively connected to the busbar 4 and the selector switch 6.

[0040] In this embodiment, an upper cover 2 is also included. The upper cover 2 is positioned and fastened to the housing 1 via a slot. The upper cover 2 is preferably made of a transparent material, allowing direct observation of whether the fuse 5 is in a normal state and whether the wiring circuit is normal. An insulating sleeve 8 may also be included, installed between the housing 1 and the terminal 7. The terminal 7 includes a first terminal 7 and a second terminal 7, which are arranged side-by-side on one side of the housing 1. The first terminal 7 is connected to the selector switch 6, and the second terminal 7 is connected to the busbar 4. The first and second terminals 7 are connected to the prototype of the robot chassis and are located in the main positive circuit of the robot chassis's power battery. The first terminal 7 is connected to the selector switch 6 via a first cable, and the second terminal 7 is connected to the busbar 4 via a second cable.

[0041] In this embodiment, the multiple fuses 5 are six fuses of 20A, 40A, 60A, 100A, 250A, and 500A specifications with an 80V voltage rating. The multiple fuses 5 are connected to the busbar 4 and the selector switch 6 via cables. The upper cover 2 and the housing 1 are fastened together using a locking mechanism; the upper cover 2 can be opened for replacement of the internal fuses 5. The internal fuses 5 are connected to the busbar 4 by bolts, and the other end of each fuse 5 is connected to the selector switch 6 via a cable. Bolts fix the fuses 5 to the insulating base plate 3, which insulates the internal circuit from the housing 1 and the upper cover 2. An insulating sleeve 8 is installed between the housing 1 and the terminal block 7 for insulation. By housing the fuses 5 of different specifications and levels within an insulating housing 1, and providing a six-position rotary selector switch 6 on the side wall of the housing 1, the connection and disconnection functions for different specifications and levels of fuses 5 can be implemented.

[0042] During the prototype debugging phase of the agricultural robot chassis, multiple fuses 5 of different specifications (voltage levels) are installed in the insulating housing 1, and external cables are connected to the terminal blocks 7. By rotating the rotary selector switch 6, rapid switching is achieved between the multiple fuses 5 of different specifications (voltage levels) to conduct corresponding tests. A debugging graded protection device for the prototype of the agricultural robot chassis's three-electric system is connected to the prototype, placing this device in the main positive line of the power battery in the electrical circuit of the robot chassis. The specifications of the multiple fuses 5 can be adjusted as needed. According to the power-on sequence and debugging current range, static / dynamic, etc., the rotary selector switch 6 is rotated sequentially to the required position and voltage level. For example, using an 80V voltage level and specifications of 20A, 40A, 60A, 100A, 250A, and 500A, the following agricultural robot chassis prototype debugging can be achieved:

[0043] Among them, the 20A fuse 5 is used for the initial power-on test of the static circuit; the 40A fuse 5 is used for the initial power-on test of the steering / variable wheel track motor; the 60A fuse 5 is used for the initial power-on test of the hub motor under no-load conditions under the lifting equipment condition; the 100A fuse 5 is used for the functional development test of the hub motor on paved roads; the 250A fuse 5 is used for the full-function development test of paved roads; and the 500A fuse 5 is used for the full-function performance test of all terrains.

[0044] This invention uses a rotary selector switch 6 to select different specifications (grades) of fuses 5, which can handle the debugging of agricultural robot chassis at different stages. It realizes the function of quick switching of multiple fuses 5 with one wiring. It connects to the electrical system of the prototype agricultural robot chassis in one go and applies the protection function of multiple specifications and grades of fuses 5, which reduces the operation time of replacing different specifications (grades) of fuses 5, and avoids the potential risks caused by the operation of disassembling and assembling fuses 5 multiple times, thus improving debugging efficiency.

[0045] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
