Detailed Description
Referring to fig. 1, an electric motor 40, a driven gear 50 and a control element (not shown) are installed inside a body 10 to form a three-in-one type according to the embodiment of the present invention.
Referring to fig. 2 and 3, the body 10 of the present embodiment includes a base 20. The base 20 has a separating layer 22 inside, and the separating layer 22 has a first assembling space 24 on one side and a second assembling space 26 on the other side. The first mating space 24 has a first gear chamber 28 in communication with a second gear chamber 30. Next, the first gear chamber 28 has a first shaft hole 32 therethrough, and the second gear chamber 30 has a second shaft hole 34 therethrough.
Referring to fig. 2 and 4, the electric motor 40 of the present embodiment has an output shaft 42, and a transmission gear 44 is coupled to an end of the output shaft 42. The electric motor 40 is installed in the machine body 10, and particularly, the transmission gear 44 is located in the first gear chamber 28 of the first assembling space 24 of the base 20. One end of the output shaft 42 passes through the first shaft hole 32.
The driven gear 50 of the embodiment disclosed has a gear shaft 52 mounted axially thereon. The driven gear 50 is located in the second gear chamber 30 of the first assembling space 24 and engages with the transmission gear 44, and one end of the gear shaft 52 passes through the second shaft hole 34, so that the gear shaft 52 passes through the bottom of the base 20, i.e. one end of the gear shaft 52 passes through the machine body 10.
Referring to fig. 2, 4 and 5, the body 10 disclosed in the present embodiment further includes a connecting base 60 in addition to the base 20. The connecting seat 60 is assembled on one side of the base 20 and corresponds to the first assembling space 24. The connecting base 60 has a through hole 62. One end of the electric motor 40 passes through the through hole 62 of the connecting base 60. A cover 70 is further installed on the connecting base 60 and is used for sealing the through hole 62, such that one end of the electric motor 50 is accommodated inside the cover 70. In addition, one end of the driven gear 50 can be pivotally installed on the connecting seat 60.
Referring to fig. 2 and 6, the present embodiment further includes a control device 80. The control device 80 is a combination of circuit board and electronic device or other similar device. The control element 80 is installed in the second assembling space 26 and electrically connected to the electric motor 40. In addition, a cover plate 90 is disposed on one side of the base 20 for enclosing the second assembly space 26.
Referring to fig. 7, since one end of the output shaft 42 of the electric motor 40 passes through the first shaft hole 32 and is located in the second assembling space 26, a shaft cover 92 can be disposed in the second assembling space 26, and one end of the output shaft 42 of the electric motor 40 is pivoted to the shaft cover 92. The control element 80 may be located on one side of the shaft cap 92. The two ends of the output shaft 42 can be matched with the bearings 100 installed in the housing cover 70 and the bearings 102 installed in the first shaft hole 32, so that the transmission gear 44 can stably rotate. Furthermore, the two ends of the gear shaft 52 of the driven gear 50 can be combined with the bearing 104 installed in the second hole 34 and the bearing 106 installed in the connecting seat 60, so that the driven gear 50 can be driven by the transmission gear 44 to generate stable rotation. One end of the gear shaft 52 penetrates the machine body 10, so that a belt pulley 110 can be installed at the position where the gear shaft 52 penetrates the machine body 10, thereby transmitting the torque generated by the electric motor 40.
Since the electric motor 40, the transmission gear 50 and the control element 80 are mounted in the machine body 10 to form a three-in-one form, the overall volume can be significantly reduced. In addition, the control element 80 is electrically connected to the electric motor 40, so that the control element 80 and the electric motor 40 are installed in the same machine body 10, and wires (not shown) for connecting the control element 80 and the electric motor 40 can be integrated inside the machine body 10. Because the wire is not exposed, the interference generated by the wire can be reduced when the electric component is installed, so that the power component is installed more quickly and conveniently.
The foregoing is a preferred embodiment and design drawing of the present invention, which is provided for illustration only and not for the purpose of limiting the scope of the invention as claimed.
