[0031] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0032] Embodiment 1:
[0033] As Figure 1-2 shown, in this embodiment, a three-in-one motor controller includes a base 1. The upper end of the base 1 is open and is provided with a housing 8. Inside the base 1, a control board 7 and a power board 2 are arranged in sequence from top to bottom. On the power board 2, a two-hole terminal 3 for connecting the power supply and two three-hole terminals 4 for connecting the traveling motor are welded. On the control board 7, two pins 6 for connecting the steering motor and a 35P IN pin 5 for connecting the function control module are welded. Corresponding slots for the two-hole terminal 3, the two three-hole terminals 4, the 35P IN pin 5, and the two pins 6 are respectively provided on the housing 8.
[0034] The beneficial effect of this embodiment is that it can meet the requirements of various industrial vehicles, integrate functions such as traveling, steering, and function control onto one controller, occupy less space, and is convenient for control.
[0035] Embodiment 2
[0036] Preferably, on the basis of Embodiment 1, a support step 1.1 for supporting the control board 7 is arranged inside the base 1. The power board 2 is fixedly installed at the bottom inside the base 1. There is a first gap between the power board 2 and the control board 7. On the power board 2, a ground support post 2.1 for supporting and connecting the ground wire of the control board 7 is provided. At the bottom of the housing 8, a pressing portion for pressing the control board 7 and extending downward is provided.
[0037] The beneficial effect of this embodiment is that there is a first gap between the power board 2 and the control board 7, and they are supported and connected to each other through the ground support post 2.1 in cooperation with a M3 ground screw.
[0038] Further, an outer shell support step for supporting the outer shell 8 is provided inside the base 1. The outer shell support step is higher than the support step 1.1 of the control board 7. Screw mounting holes are provided at the four corners of the outer shell support step. After the outer shell 8 is installed, a pressing portion is provided on one side of the bottom edge of the outer shell 8 and presses tightly on the control board 7. Together with the grounding screw inside the grounding support column 2.1, the control board 7 can be stably fixed.
[0039] It should be noted that currently, controllers are divided into several core components such as a controller base, a power board, a terminal block, a control board, and an outer shell. The terminal block and the power board are all installed with multiple screws. The flatness requirements and assembly tolerance control for the terminal block and the power board are extremely strict. Moreover, the production and assembly processes are very cumbersome and the production cost is high.
[0040] Embodiment 3
[0041] Preferably, on the basis of Embodiments 1-2, support blocks are provided at the upper ends of the two-hole terminal block 3 and the two three-hole terminal blocks 4, and the support blocks are in contact with the lower end of the control board 7.
[0042] The beneficial effect of this embodiment is that the support block can maintain the stability of the control board and fully withstand the vibration conditions of the vehicle.
[0043] Embodiment 4
[0044] Preferably, on the basis of Embodiments 2-3, the support step 1.1 is rectangular.
[0045] The beneficial effect of this embodiment is that the structure is simple and can well support the control board 7.
[0046] Embodiment 5
[0047] Preferably, on the basis of Embodiments 2-4, a first screw hole for fixing the power board 2 is provided at the inner edge of the bottom of the base 1.
[0048] The beneficial effect of this embodiment is that the fixing effect is good and it is convenient for assembly and disassembly.
[0049] Embodiment 6
[0050] Preferably, on the basis of Embodiments 1-5, a silicone sealing pad 9 is provided between the slots of the 35PIN pin 5 and the 35PIN pin 5.
[0051] The beneficial effect of this embodiment is that the two adopt an interference fit. Since the silicone strip has elasticity, it deforms after being squeezed, so as to achieve the purpose of waterproofing. After the outer shell 8 and the die-cast aluminum base 1 are assembled, they are locked with 5 M3 screws.
[0052] Embodiment 7
[0053] Preferably, based on embodiments 1-6, mounting holes are provided on the four edges of the base 1 .
[0054] The beneficial effect of this embodiment is that it is easy to install on other components.
[0055] Furthermore, the base 1 is rectangular, and mounting holes are provided at its four corners.
[0056] Example 8
[0057] Preferably, based on Embodiments 1-7, the base 1 is made of aluminum.
[0058] The beneficial effects of this embodiment are: lightness and corrosion resistance.
[0059] Of course, the base 1 of the present application may also be made of other materials, and is not limited thereto.
[0060] Example 9
[0061] Preferably, based on Examples 1-7, there is a second gap for filling waterproof silicone between the two-hole terminal 3 and the corresponding groove of the housing 8 and between the two three-hole terminal 4 and the corresponding groove of the housing 8.
[0062] The beneficial effect of this embodiment is that waterproof silica gel is injected into the gap between the edge of the shell 8 and the edge of the die-cast aluminum base 1, and into the second gap reserved between the shell 8 and the two-hole terminal 3 and the three-hole terminal 4, so as to meet the waterproof requirements.
[0063] Example 10
[0064] Preferably, based on embodiments 1-9, the bottom of the base 1 is provided with anti-slip grooves.
[0065] The beneficial effect of this embodiment is: increasing the friction with the human hand to prevent falling.
[0066] The beneficial effects of the utility model are:
[0067] 1. This all-in-one controller can meet the requirements of various industrial vehicles, integrating travel, steering and function control into one controller. The two-hole terminal 3 is the positive and negative poles of the controller's power supply, and the controller has two three-hole terminals 4 for brushless motor control interfaces, which can control two brushless motors at the same time. The two integrated 2*3 pins 6 can be used for steering motor control signal output and input, and the interface 35PIN pin 5 can be used as a functional interface.
[0068] Second, the controller not only has a high degree of functional integration, but also abandons the traditional controller assembly method. The two-hole terminal 3 and the three-hole terminal 4 are made into an integrated terminal respectively, and the terminal is directly attached to the power board by reflow soldering. Compared with the traditional method of using screws to lock the terminals separately, this solution simplifies the assembly process, avoids poor contact of the terminals caused by screw loosening, and greatly improves the production efficiency and reliability of the controller.
[0069] Third, compared with the traditional controller, there is only one M3 grounding screw for the control board 7 assembly, but it can also ensure the reliability of the controller. As Figure 2 shown, lean the edge of the control board 7 against the supporting step 1.1 of the aluminum base, and then tightly press the control board 7 on the die-cast aluminum base 1 through the housing 8. The upper end of the control board 7 presses the control board 7 on the two three-hole terminals 4 in the same way. In this way, the control board 7 has a total of three support points, a support surface, a locking point and a pressing surface. At this time, the control board 7 can fully withstand the vibration conditions of the vehicle.
[0070] Fourth, for the waterproof solution of the controller, at the 35PIN pin 5, the housing 8 presses the silicone sealing gasket 9, and the two are in interference fit. Since the silicone strip has elasticity, it deforms after being extruded, so as to achieve the purpose of waterproofing. After the housing 8 and the die-cast aluminum base 1 are assembled, they are locked with 5 M3 screws. In the gap between the edge of the housing 8 and the edge of the die-cast aluminum base 1, waterproof silicone is injected into the grooves left between the housing 8 and the two-hole terminal 3 and the three-hole terminal 4, so as to meet the waterproof requirements.
