Embodiment 1
[0046] figure 1 A schematic structural diagram of the bracket assembly 100 provided in this embodiment, figure 2 For the exploded view of the motor assembly 20 formed by the cooperation of the bracket assembly 100 and the motor 21, please refer to figure 1 and figure 2 shown.
[0047] The bracket assembly 100 is used to cooperate with the motor 21 and is installed in the base of the electric toothbrush 30 as a whole. Since the bracket assembly 100 includes the first spring washer 16, the second spring washer 18, the bracket main body 10 and the cover plate 13, the first spring The pad 16 and the second spring pad 18 have elasticity, the cover plate 13 is fastened with the main body 10 of the bracket, and forms an accommodation chamber 14 for accommodating the motor 21, the motor 21 includes an opposite output end and a tail end 216, and the output end is provided with The power output shaft 215, the first spring washer 16 is arranged at the first end of the housing chamber ...
Embodiment 2
[0080] This embodiment provides a motor assembly 20, including a motor 21 and a bracket assembly 100 as provided in Embodiment 1 above, and the specific description is as follows:
[0081] Figure 13 is a schematic structural view of the motor assembly 20, Figure 14 is a structural schematic diagram of the motor 21, please refer to Figure 13 and Figure 14 shown.
[0082] Since the bracket body 10 and the cover plate 13 enclose the accommodation chamber 14, the motor 21 includes an output end and a tail end 216, the motor 21 is embedded in the accommodation chamber 14, and the output end cooperates with the first end of the accommodation chamber 14 through the first spring washer 16 Fixed, the tail end 216 is fixed with the second end of the housing cavity 14 through the second elastic washer 18, under the condition that the axis of the output shaft 215 of the motor 21 and the extension track of the bracket main body 10 form the above preset included angle, the structure ...
Embodiment 3
[0088] Embodiment 3 provides an electric toothbrush 30, including the motor assembly 20 provided in Embodiment 2, or the bracket assembly 100 provided in Embodiment 1, Figure 15 For the structural schematic diagram of electric toothbrush 30, please refer to Figure 15 As shown, the specific description is as follows:
[0089] The electric toothbrush 30 also includes a motor 21, a toothbrush head 31 and a handle shell 32. The bracket assembly 100 cooperates with the motor 21 to form a motor assembly 20. The motor assembly 20 is installed in the handle shell 32. The extension track of the bracket body 10 is aligned with the handle shell 32. The extension track of the toothbrush head 31 is the same, the output shaft 215 of the motor 21 is fixedly connected with the toothbrush head 31, and the reciprocating motion of the toothbrush head 31 is driven by the motor 21, so that the axis line of the toothbrush head 31 and the extension track of the handle shell 32 form the above-menti...
