Description

Technical Field

[0001] This utility model relates to the field of electrical tools, and in particular to a water drill. Background Technology

[0002] Water drills, as a type of power tool widely used in construction and decoration, typically employ AC or DC motors as their core drive components. To improve drilling efficiency, modern water drills often feature multi-speed designs to accommodate the processing needs of materials with varying hardness.

[0003] However, traditional gear shifting methods have obvious drawbacks: if high-speed shifting is used, a large impact force will be generated at the moment of gear meshing, which can easily lead to damage to the tooth surface with long-term use; if manual deceleration or shifting while stopping is used, it will affect work efficiency and user experience, especially in delicate operations that require precise control of speed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water drill that can not only reduce shifting impact, improve work efficiency and improve operating accuracy, but also enhance user experience and achieve compatibility optimization.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A water drill includes a housing, on which a motor controller, a motor, and a shaft system are sequentially arranged. The motor controller is electrically connected to the motor. The shaft system includes an input shaft system, an output shaft system, and a shifting component for changing the transmission ratio between the input and output shaft systems. The input shaft system is connected to the motor. The motor controller integrates a shifting module for realizing a low-speed rotation mode of the motor. The water drill also includes a shifting switch disposed on the housing and electrically connected to the shifting module. When shifting gears, pressing the shifting switch triggers the shifting module, thereby activating the motor to enter the low-speed rotation mode and providing assistance for shifting gears.

[0007] Furthermore, the input shaft system includes a first input shaft system and a second input shaft system.

[0008] Furthermore, the motor operates at a speed of 2000-5000 rpm in low-speed rotation mode.

[0009] Furthermore, the motor shaft is provided with a drive gear, and the first input shaft system includes a first input shaft. The first input shaft is provided with a driven gear, a first gear, a second gear and a third gear in sequence along its axial direction. The drive gear on the motor shaft meshes with the driven gear.

[0010] Furthermore, the second input shaft system includes a second input shaft arranged parallel to the axis of the first input shaft. The second input shaft is provided with a first clutch gear, a second clutch gear, a third clutch gear, and a fourth gear in sequence along its axial direction. The first clutch gear and the third clutch gear correspond to the first gear and the third gear, respectively. The first clutch gear and the third clutch gear are rotatably sleeved on the second input shaft, and the second clutch gear slides axially with the second input shaft through a spline.

[0011] Furthermore, the output shaft system includes an output shaft arranged parallel to the axis of the second input shaft, and the output shaft is provided with a fifth gear that meshes with the fourth gear.

[0012] Furthermore, the shift assembly includes a clutch, a shift fork, and a shift knob mounted on the housing. The clutch includes a first clutch and a second clutch, both of which are mounted on the second input shaft. The first clutch is fixedly connected to the end face of the second clutch gear facing the first clutch gear; the second clutch is fixedly connected to the end face of the second clutch gear facing the third clutch gear. The shift knob is rotatably mounted on the housing and drives the first clutch to make axial displacement along the second input shaft via the shift fork. Specifically: when the shift knob rotates in a first direction, it drives the first clutch to engage with the first clutch gear, causing the first gear and the first clutch gear to form a transmission engagement; when the shift knob rotates in a second direction, it drives the first clutch to engage the second clutch with the third clutch gear, thereby causing the third gear and the third clutch gear to form a transmission engagement; when the shift knob is in the intermediate position, the second gear and the second clutch gear maintain transmission engagement.

[0013] Furthermore, the first clutch has an annular groove on its outer periphery, one end of the shift fork is fixedly connected to the lower end face of the shift knob, and the other end of the shift fork is a shift fork shaft inserted into the annular groove. The axis of the shift knob is parallel to the axis of the shift fork shaft.

[0014] Furthermore, the first clutch gear and the first clutch facing each other are respectively provided with first engagement teeth that can mesh with each other, and the second clutch and the third clutch gear facing each other are respectively provided with second engagement teeth that can mesh with each other.

[0015] Furthermore, the water drill also includes a power switch mounted on the housing, which is electrically connected to the motor controller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, reduce shift shock: By actively reducing speed before shifting through the shift module, the relative speed difference during gear meshing is significantly reduced, effectively alleviating the impact force on the tooth surface caused by traditional high-speed shifting and greatly extending the service life of the gear set.

[0018] Secondly, it improves work efficiency: there is no need to completely stop the machine or rely on manual intervention to slow down. The gear shifting process is simple and convenient, which can shorten the gear shifting time. It is especially suitable for complex working conditions that require frequent speed changes.

[0019] Third, improves operating precision: Smooth low-speed shifting avoids unexpected damage to the processed material caused by sudden changes in speed. Especially when drilling brittle materials such as ceramic tiles and glass, it can maintain the integrity of the processed surface and improve the yield.

[0020] Fourth, enhance user experience: eliminate the jerky feeling of manual deceleration or gear shifting, reduce the physical burden on the operator, and reduce the risk of human error through intelligent control.

[0021] Fifth, compatibility optimization: The low-speed rotation module can be integrated into the existing motor controller without additional mechanical structure modification, making the cost controllable and easy to promote to different power models. Attached Figure Description
