Description

Technical Field

[0001] This utility model relates to the field of power tools, and in particular to a capacitor and controller mounting structure and an angle grinder. Background Technology

[0002] Electric angle grinders are a commonly used tool. The internal installation structure of current electric angle grinders can be seen in patent publication document CN208276682U. In this structure, two very important control components (i.e., capacitor and controller) are directly clamped inside the casing. However, the casing will generate a lot of vibration when the angle grinder is running. The vibration of the casing will be directly transmitted to the capacitor and controller, causing the electronic components inside the capacitor and controller to loosen or age faster due to vibration, thus reducing the service life of the capacitor and controller. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a capacitor and controller mounting structure and an angle grinder. In this mounting structure, the capacitor and controller do not contact the inner wall of the housing. The shock-absorbing sleeve plays a role in shock absorption and buffering for the capacitor and controller, reducing the vibration experienced by the capacitor and controller, and effectively extending the service life of the capacitor and controller.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A capacitor and controller mounting structure includes a housing, a capacitor, and a controller. The housing has a snap-fit ​​opening, and the capacitor and controller are snapped into the snap-fit ​​opening. The structure is characterized by further including a first shock-absorbing sleeve and a second shock-absorbing sleeve. The first shock-absorbing sleeve is sleeved on the capacitor, and the second shock-absorbing sleeve is sleeved on the controller. Neither the capacitor nor the controller is in contact with the housing, while the first and second shock-absorbing sleeves are in contact with the housing.

[0006] In this capacitor and controller mounting structure, a soft rubber shock-absorbing sleeve is fitted onto the capacitor and controller. The soft rubber shock-absorbing sleeve contacts the inner wall of the housing. Since the capacitor and controller do not contact the inner wall of the housing, the shock-absorbing sleeve plays a role in shock absorption and buffering, reducing the vibration experienced by the capacitor and controller, and effectively extending the service life of the capacitor and controller.

[0007] Optionally, there are multiple capacitors, and each capacitor is fitted with a first shock-absorbing sleeve at both ends. The capacitors do not contact each other, nor do they contact the controller.

[0008] Both ends of the capacitor are fitted with a first shock-absorbing sleeve to ensure good shock absorption. At the same time, the capacitors do not come into contact with each other or with the controller, which can avoid mutual interference between the capacitors and between the capacitors and the controller.

[0009] Optionally, the second shock-absorbing sleeve is fitted onto the housing of the controller, and the second shock-absorbing sleeve is fitted onto both ends of the housing.

[0010] Optionally, the housing includes a first inner cavity and a second inner cavity, the capacitor is disposed in the first inner cavity, and the controller is disposed in the second inner cavity.

[0011] The capacitor and controller are located in separate internal cavities to facilitate rapid heat dissipation.

[0012] Optionally, the first inner cavity is curved, the second inner cavity is straight, and the first inner cavity is connected to the second inner cavity.

[0013] Optionally, the first shock absorber sleeve is a first shock absorber sleeve made of rubber, and the second shock absorber sleeve is a second shock absorber sleeve made of rubber.

[0014] An angle grinder includes a capacitor and controller mounting structure as described above.

[0015] Optionally, the housing is provided with a rotating shaft, and the rotating shaft is provided with a grinding blade.

[0016] The beneficial effects of this utility model are: the capacitor and controller do not contact the inner wall of the housing, the shock-absorbing sleeve plays a role in shock absorption and buffering of the capacitor and controller, reducing the vibration experienced by the capacitor and controller, and effectively extending the service life of the capacitor and controller.

Since capacitor 2 and controller 3 do not contact the inner wall of housing 1, the shock-absorbing sleeve plays a role in shock absorption and buffering of capacitor 2 and controller 3, reducing the vibration experienced by capacitor 2 and controller 3, and effectively extending the service life of capacitor 2 and controller 3.
