[0038] Figure 1A schematic diagram of the structure of a power tool 100 according to an embodiment of the present invention is shown. Figure 2 for Figure 1 A schematic diagram of the exploded structure of a power tool 100. Figure 1 and 2 As shown, this utility model proposes a housing assembly and a power tool 100. The housing assembly of this utility model includes a housing 10, a handle housing 30, and a vibration damper 20. The handle housing 30 is disposed at one end of the housing 10 along its own axis. The vibration damper 20 has a ring structure and is disposed between the housing 10 and the handle housing 30, and is sleeved on the outside of one of the housing 10 and the handle housing 30. The vibration damper 20 is configured to connect the housing 10 and the handle housing 30.
[0039] By using the housing assembly in this technical solution, the vibration damper 20 is sleeved on the outside of the housing 10 or the handle housing 30, which can provide certain support to the inside of the vibration damper 20, thereby improving the stability of the vibration damper 20. The handle housing 30 is connected to the housing 10 through the vibration damper 20, which can reduce the vibration transmitted from the housing 10 to the handle housing 30, improve the user's work comfort and user experience, and thus improve work efficiency.
[0040] Specifically, in this embodiment, the vibration damping member 20 is sleeved on the outside of the housing 10 and is connected to the housing 10 and the handle housing 30 respectively. The vibration damping member 20 is fixedly connected to the housing 10, and the housing 10 is connected to the handle housing 30 through the vibration damping member 20. The vibration transmitted from the housing 10 to the handle housing 30 can be reduced through the vibration damping member 20.
[0041] Specifically, in this embodiment, the damping member 20 can also be sleeved on the outside of the handle shell 30 and connected to the housing 10 and the handle shell 30 respectively. The damping member 20 is fixedly connected to the handle shell 30, and the handle shell 30 is connected to the housing 10 through the damping member 20. The vibration transmitted from the housing 10 to the handle shell 30 can be reduced by the damping member 20.
[0042] In some embodiments of this utility model, such as Figure 3 As shown, the housing 10 includes a first housing 11 and a second housing 12 connected along its own axis. The second housing 12 is located between the first housing 11 and the handle housing 30. The damping member 20 is sleeved on the outer periphery of the end of the second housing 12 facing the handle housing 30. In this embodiment, the outer diameter of the second housing 12 is smaller than the outer diameter of the first housing 11. When the damping member 20 is sleeved on the second housing 12, it can abut against the first housing 11, which not only positions the damping member 20 but also limits its movement, ensuring the stability of the damping member 20 during the damping process.
[0043] Specifically, in this embodiment, the second housing 12 and the damping member 20 can be connected by adhesive bonding, and can also be connected by other fasteners, thereby realizing the connection between the housing 10 and the damping member 20.
[0044] In some embodiments of this utility model, such as Figure 4 As shown, the vibration damper 20 includes a first damping body 21 and a second damping body 22 connected to the first damping body 21. Both the first damping body 21 and the second damping body 22 are annular. The first damping body 21 is sleeved on the outer periphery of the end of the second housing 35 facing the handle housing 30. The two ends of the first damping body 21 in the axial direction abut against the housing 10 and the handle housing 30, respectively. The handle housing 30 has a receiving cavity 33 on the side facing the housing 10, and the second damping body 22 is connected to the inner wall of the receiving cavity 33. In this embodiment, the first damping body 21 is sleeved outside the second housing 12 to realize the connection between the vibration damper 20 and the housing 10. The second damping body 22 is located inside the handle housing 30 and is snap-fitted into the handle housing 30 to realize the connection between the vibration damper 20 and the handle housing 30.
[0045] Specifically, in this embodiment, along the axial direction of the housing 10, both ends of the first damping body 21 abut against the housing 10 and the handle housing 30 respectively, enabling the housing 10 and the handle housing 30 to position and limit the first damping body 21, ensuring the stability of the first damping body 21 during the damping process. Furthermore, the first damping body 21 is sandwiched between the housing 10 and the handle housing 30, achieving a tight fit between the housing 10 and the first damping body 21, as well as between the first damping body 21 and the handle housing 30, further enhancing the damping effect of the damping component 20.
[0046] In some embodiments of this utility model, such as Figure 4 and 5 As shown, the outer surface of the second damper 22 is provided with a first connecting portion 221, and the inner wall surface of the handle housing 30 facing the housing 10 is provided with a first mating portion 31. The first connecting portion 221 and the first mating portion 31 are connected in a mating manner. In this embodiment, the concave-convex fit increases the connection strength and stability in structure. Through the combination of the concave and convex parts, the stability between the damper 20 and the handle housing 30 can be increased, ensuring that the second damper 22 will not detach from the handle housing 30 due to simple vibration during vibration.
[0047] In some embodiments of this utility model, such as Figure 4 and 5As shown, the first connecting part 221 is an annular boss, and the first mating part 31 is an annular groove, with the annular boss inserted into the annular groove. In this embodiment, the mating of the annular boss and the annular groove enables the annular boss to be engaged in the annular groove, thereby limiting and positioning the second damping body 22 and the handle housing 30 in the axial direction of the housing 10, thus improving the stability between the handle housing 30 and the damping member 20.
[0048] Specifically, in other embodiments of this utility model, the first mating part 31 can be an annular boss and the first connecting part 221 can be an annular groove. The annular boss is inserted into the annular groove, which can also achieve the same result of the annular boss being engaged in the annular groove, so that the second damping body 22 and the handle shell 30 are limited and positioned in the axial direction of the housing 10, thereby improving the stability between the handle shell 30 and the damping member 20.
[0049] In some embodiments of this utility model, such as Figure 3 and 4 As shown, the inner wall of the first damper 21 is provided with a second connecting portion 211, and the outer surface of the second housing 12 is provided with a second mating portion 121. The second connecting portion 211 and the second mating portion 121 are in a concave-convex fit. In this embodiment, the second connecting portion 211 is a boss, and the second mating portion 121 is a groove. The fit between the boss and the groove enables the first damper 21 to be limited and positioned along its own circumferential direction, ensuring that the first damper 21 will not rotate in its own circumferential direction during the damping process, thereby improving reliability and stability.
[0050] Specifically, in other embodiments of this utility model, the inner wall surface of the first damping body 21 may be provided with a groove, and the outer surface of the second housing 12 may be provided with a boss. This can also achieve the limiting and positioning of the first damping body 21 along its own circumferential direction, ensuring that the first damping body 21 will not rotate in its own circumferential direction during the damping process, thereby improving reliability and stability.
[0051] In some embodiments of this utility model, such as Figure 4 and 5 As shown, the second damper 22 has a positioning groove 222 on the side opposite to the first damper 21, and a positioning member 32 is provided on the inner wall of the handle housing 30, which is inserted into the positioning groove 222. In this embodiment, when the handle housing 30 is connected to the damper 20, the positioning member 32 in the handle housing 30 can be inserted into the positioning groove 222 along the axial direction of the housing 10, thereby limiting and positioning the rotation of the second damper 22 in its circumferential direction. Combined with the combination structure of the second connecting part 211 and the second mating part 121, the stability between the damper 20 and the handle housing 30 is further improved.
[0052] In some embodiments of this utility model, such as Figure 5 As shown, the handle shell 30 has a receiving cavity 33. The handle shell 30 includes a first shell 34 and a second shell 35, which together form the receiving cavity 33. In this embodiment, the handle shell 30 is designed as a separate structure of the first shell 34 and the second shell 35, which facilitates the connection between the handle shell 30 and the vibration damper 20. First, the annular groove of the first shell 34 is engaged with the annular boss of the vibration damper 20, and then the second shell 35 is engaged with the annular boss of the vibration damper 20, thus achieving the splicing of the first shell 34 and the second shell 35, and also achieving the connection between the handle shell 30 and the vibration damper 20.
[0053] Specifically, in this embodiment, the positioning member 32 can be disposed on the first housing 34 or on the second housing 35.
[0054] In some embodiments of this utility model, the vibration damping component 20 is a rubber component. In this embodiment, the rubber material has high elasticity and viscoelasticity, which enables the rubber component to exhibit good vibration damping effect in various vibration environments. The elasticity of the rubber can absorb and disperse vibration energy, thereby reducing the vibration transmitted from the housing 10 to the handle housing 30.
[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
