[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] like Figures 2 to 12As shown, the present application provides a mounting bracket 10 of a personal care device 100, including an inner shell 11 and two vibration-damping pads 12; the inner shell 11 is in the shape of an elongated strip and has a first cavity 113 and a second cavity 114 distributed along the length direction, the first cavity 113 is used to accommodate the motor 20, and the second cavity 114 is used to accommodate the battery 30, the inner shell 11 includes a first shell 111 and a second shell 112 distributed along the width direction, the first shell 111 and the second shell 112 are spliced ​​together to form the first cavity 113 and the second cavity 114; the two vibration-damping pads 12 are respectively attached to the first shell 111 and the second shell 112, and extend along the length direction of the inner shell 11.

[0039] The first shell 111 and the second shell 112 are spliced ​​together to quickly form a first cavity 113 for accommodating the motor 20 and a second cavity 114 for the power supply. When the first shell 111 and the second shell 112 are spliced ​​together, the motor 20 and the battery 30 can be pre-installed between the first shell 111 and the second shell 112, and then the first shell 111 and the second shell 112 are fixed, so that the assembly of the mounting bracket 10, the motor 20 and the battery 30 can be further simplified.

[0040] If the inner shell 11 is divided in length, that is, the structure for installing the motor 20 and the structure for installing the battery 30 are divided in length, then during installation, the motor 20 needs to be assembled into the upper shell first, and this installation process will cause the first installation error in the length direction; then the battery 30 is installed into the lower shell, and this installation process will cause the second installation error in the length direction; finally, the upper and lower shells are fixed together, and in this process, the third installation error will occur in the length direction. After the three installation errors are superimposed, the inner shell 11 and the structure inside the inner shell 11 have a larger installation error in the length direction relative to the outer shell 40.

[0041] However, by adopting the design of splitting the inner shell 11 into left and right parts, the occurrence of the third installation error can be avoided, and the installation bases of the motor 20 and the battery 30 are consistent, and are the first shell 111 or the second shell 112 of the inner shell 11, which is conducive to further ensuring the relative position of the motor 20 and the battery 30.

[0042] In addition, by arranging the vibration-damping pad 12 in the first housing 111 and the second housing 112 , the vibration-damping pad 12 can adapt to part of the installation error by deformation, thereby reducing the error accumulation. At the same time, the vibration-damping pad 12 can also reduce the vibration of the motor 20 and the battery 30 .

[0043] In this embodiment, if Figures 2 to 12As shown, the cross-sectional shape of the inner shell 11 is various; for example, the cross-sectional shape of the inner shell 11 can be circular, square, oval and other shapes. Among them, the first shell 111 and the second shell 112 are detachably connected to enable the motor 20 and the power supply in the mounting bracket 10 to be replaced. The first shell 111 and the second shell 112 are connected by a buckle 115; the setting of the buckle 115 can facilitate the disassembly and assembly of the first shell 111 and the second shell 112. Of course, in other embodiments, the first shell 111 and the second shell 112 can also be fixed by screws, welding or bonding. Specifically, the buckle 115 includes a slot 1151 and a tongue 1152; the slot 1151 is set in the first shell 111, and the tongue 1152 is set in the second shell 112; when the first shell 111 and the second shell 112 are assembled, the tongue 1152 is connected in the slot 1151 to enable the first shell 111 and the second shell 112 to be fixed.

[0044] In this embodiment, if Figures 5 to 9 As shown, the outer surface of the first shell 111 is provided with a limiting rib 1111, which extends along the length direction of the inner shell 11 and spans the first cavity 113 and the second cavity 114; the setting of the limiting rib 1111 can locate the installation position of the first shell 111 and the second shell 112, so as to further reduce the assembly error of the mounting bracket 10; in addition, it can also make the first shell 111 have a strong anti-torque effect. When the first shell 111 and the second shell 112 are connected, the outer edge of the second shell 112 can abut against the limiting rib 1111. The outer side of the first shell 111 and / or the second shell 112 is provided with a reinforcing rib 1112, which can strengthen the structural strength of the first shell 111 and the second shell 112.

[0045] In this embodiment, if Figures 4 to 12 As shown, the vibration damping pad 12 has a certain elasticity; when the motor 20 and the battery 30 are assembled in the inner shell 11, the vibration damping pad 12 can be deformed under the pressure of the battery 30 and the motor 20, so as to stably fix the motor 20 and the battery 30 in the inner shell 11. At least one vibration damping pad 12 includes a first vibration damping portion 123 and a second vibration damping portion 124 that are integrally arranged, the first vibration damping portion 123 is located in the first cavity 113, and the second vibration damping portion 124 is located in the second cavity 114; the first vibration damping portion 123 and the second vibration damping portion 124 can be assembled to the inner shell 11 simultaneously, and the first vibration damping portion 123 and the second vibration damping portion 124 do not need to be fixed to each other, so as to simplify the assembly of the vibration damping pad 12.

When the vibration-damping pad 12 is embedded in the mounting groove 1113, the vibration-damping pad 12 can be fixed to the first shell 111 or the second shell 112 by bonding or other means. Among them, the local depressions of the first shell 111 and the second shell 112 form the mounting groove 1113.
