[0047] The present invention will be further described in detail below with reference to specific embodiments, so that those skilled in the art can more clearly understand the present invention.

[0048] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to electrical connections, fixed connections, detachable connections, or even integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0049] This embodiment provides a dual-path sweeper driver, including a housing 1.

[0050] The housing 1 contains two drive modules 3, each with positive and negative terminals, a signal input interface 10, and a signal output interface 7.

[0051] For example, see Figure 2The inner wall of the housing 1 is equipped with two drive modules 3. Each drive module 3 has positive and negative terminals (i.e., positive input 8 and negative input 9), a signal input interface 10, and a signal output interface 7. The positive input 8 and negative input 9 are used to connect to the positive and negative terminals of an external power supply, allowing the drive modules 3 to be powered by an external power source. The signal input interface 10 is used to connect to an external host computer, allowing the host computer to transmit control signals to the drive modules 3. The two drive modules 3 are assigned different CAN communication ID addresses, and the external host computer establishes a CAN communication protocol with each drive module 3, controlling each drive module 3 separately. The signal output interface 7 is used to connect to a motor, allowing the drive modules 3 to transmit signals to the motor, thereby driving the motor to run. The two signal output interfaces 7 are connected to two motors respectively, each driving one motor, thus enabling the two motors to perform different tasks.

[0052] The side wall of housing 1 is provided with a power cable connector 4, a control cable connector 5, and two motor cable connectors 6.

[0053] For example, see Figure 1-2 The left side wall of the housing 1 is equipped with a power cable connector 4, a control cable connector 5, and two motor cable connectors 6. The inner end of the power cable connector 4 can simultaneously connect to the positive and negative terminals of two drive modules 3, while the outer end of the power cable connector 4 connects to the positive and negative terminals of an external power source. The inner end of the control cable connector 5 can simultaneously connect to the signal input interfaces 10 of two drive modules 3, while the outer end of the control cable connector 5 connects to the signal output terminal of the host computer. The inner ends of the two motor cable connectors 6 are respectively connected to the signal output interfaces 7 of the two drive modules 3, and the outer ends of the two motor cable connectors 6 are respectively connected to the two motors, enabling independent control of the two motors.

[0054] In summary, the dual-path sweeper driver provided in this embodiment integrates two drive modules 3 into one housing 1, which simplifies the external structure, reduces external connectors and wiring, and is suitable for 24V low-voltage small sweepers.

[0055] Based on the above technical solution, in the technical solution provided in this embodiment, the shell 1 has an opening on one side, and a cover plate 2 is provided on the opening side of the shell 1. A groove 12 is provided on the side wall of the shell 1 along the outer edge of the opening. A boss 11 that matches the groove 12 is provided on the cover plate 2. The boss 11 is embedded in the groove 12, and a sealing ring is held between the boss 11 and the groove 12.

[0056] For example, see Figure 1 , Figure 3 The bottom end of the housing 1 is open, and a groove 12 is formed at the bottom end of the housing 1. The groove 12 is arranged along the outer edge of the bottom end opening of the housing 1. See also Figure 4The cover plate 2 is provided with an annular protrusion 11. When the cover plate 2 is closed on the bottom opening side of the housing 1, the protrusion 11 is embedded in the groove 12 and squeezes the sealing ring, effectively improving the sealing performance.

[0057] The cover plate 2 and the housing 1 can be connected by bolts.

[0058] For example, see Figure 1-2 The cover plate 2 is connected to the housing 1 by fourteen bolts. The bolt connection is firm and stable and easy to install.

[0059] The cover plate 2 has a transparent window 13.

[0060] For example, see Figure 4 During maintenance, the interior of the casing 1 can be directly observed through the transparent window 13 without the need to remove the fourteen bolts.

[0061] The drive module 3 is typically integrated onto the circuit board 22, which is located on the inner wall of the housing 1. For quick installation or removal of the circuit board 22 during maintenance, a guide post 18 is provided on the inner wall of the housing 1. A groove 19 is formed on the side wall of the guide post 18, and a slider 20 slides within the groove 19. A spring 21 is also provided within the groove 19, with its two ends connected to the inner wall of the groove 19 and the slider 20, respectively. The circuit board 22 has mounting holes that mate with the guide post 18.

[0062] For example, see Figure 5 In its natural state, the slider 20 is partially exposed outside the groove 19. When installing the circuit board 22, the slider 20 is pressed into the groove 19, the spring 21 is compressed, and then the mounting hole of the circuit board 22 is fitted onto the guide post 18 until the circuit board 22 contacts the inner wall of the housing 1. The circuit board 22 is just detached from the slider 20, the spring 21 returns to its original state, and the slider 20 slides out to its initial position. At this time, the slider 20 can limit the circuit board 22, pressing the circuit board 22 firmly against the inner wall of the housing 1.

[0063] The top of the guide post 18 may be provided with a chamfered structure, which facilitates the quick insertion of the guide post 18 into the mounting hole and effectively improves the installation efficiency.

[0064] The top of the slider 20 can also be chamfered, so that when fitting it into the mounting hole, there is no need to manually press the slider 20. The mounting hole can automatically press the slider 20 into the groove 19, making the operation simple and convenient.

[0065] In the technical solution provided in this embodiment, the side wall of the housing 1 is provided with a plurality of pins 16, the cover plate 2 is provided with a relief groove 17 adapted to the pins 16, the pins 16 are embedded in the relief groove 17, and the pins 16 are provided with through holes in the upper and lower parts.

[0066] For example, see Figure 3The housing 1 has four pins 16 fixed at its bottom end, and the cover plate 2 has four clearance slots 17. The clearance slots 17 are adapted to the pins 16. When the cover plate 2 is closed with the opening side of the housing 1, the four pins 16 are respectively embedded in the four clearance slots 17. This design allows the housing 1 to be installed on other devices through the through holes of the pins 16, avoiding damage to the structure of the housing 1 or the cover plate 2 during installation and ensuring the integrity of the housing 1 and the cover plate 2.

[0067] The thickness of pin 16 is greater than that of cover plate 2. Pin 16 serves a supporting function. For example, when housing 1 is placed on the ground, pin 16 can directly contact the ground, while cover plate 2 is suspended in the air. This protects cover plate 2 and also prevents housing 1 from directly contacting water stains on the ground.

[0068] In the technical solution provided in this embodiment, a heat sink can be provided on the inner wall of the housing 1, and the drive module 3 is mounted on the heat sink. The heat sink can improve the heat dissipation effect of the drive module 3.

[0069] Furthermore, heat dissipation fins 14 are provided on the side wall of the housing 1. The provision of heat dissipation fins 14 can improve the heat dissipation effect of the housing 1. For example, the heat from the drive module 3 can be transferred to the heat dissipation fins 14 through the heat sink, and then transferred to the outside of the housing 1.

[0070] In the technical solution provided in this embodiment, a vent valve 15 is provided on the side wall of the housing 1.

[0071] For example, see Figure 3 The vent valve 15 is used for ventilation, effectively solving the temperature difference problem between the inside and outside of the housing 1, thereby preventing the formation of internal condensation that could damage the internal modules. A sealing ring is clamped between the vent valve 15 and the side wall of the housing 1, which can improve the sealing performance and enable the driver to achieve an IP66 protection rating.

[0072] The mechanisms, components, and parts in this invention that are not specifically described are all existing structures in the prior art and can be purchased directly from the market.
