Description

Multidirectional mounting structure of electric scooter drive

The present invention relates to the installation of the drive on the frame of the electric scooter, which can be installed in more different angle directions, and also allows the drive to be more securely and firmly locked on the frame, so that the same drive can be It can be used on various frames of different designs to avoid obstacles and smooth installation, and also avoid looseness, vibration and noise of the drive.

As shown in FIG. 1 and FIG. 2, a conventional electric scooter drives a wheel 1 to rotate the wheel, and a differential gear set (not shown) is disposed in the casing 111 including a shifting device 11. A motor 12 for driving the differential speed gear set is disposed above the casing 111, and a power output shaft 112 extending from both ends of the casing 111 for the wheel to be mounted and rotated by the differential gear set is mounted. In turn, the output shaft 112 drives the wheels to rotate to allow the electric scooter to travel.

At the same time, the two ends of the casing 111 of the shifting device 11 of the above-mentioned actuator 1 are a housing portion 113 having a rectangular outer shape, and the two bearing housing portions 113 correspond exactly to the frame 2 of the electric scooter, that is, the two bearing portions 113 sits on the frame 2, and then each end is provided with a "ㄇ"-shaped fixing seat 13, which clamps the bearing seat portion 113 and locks on the frame 2, so that the entire driver 1 is locked in the vehicle. On the shelf 2.

In addition, in order to allow the electric scooter to park the brakes, a brake 14 is usually installed at the rear end of the motor 12 to allow the driver to brake when the vehicle is stopped by the brake 14.

But because of the electric scooter manufacturers who use the same drive, they are designed to produce a car with a distinctive shape, and in order to accommodate the installation of components such as seats, batteries, bumpers, and even car shells, the frame The architectures also have different types of designs; therefore, when the same driver is mounted on the frame at the rear wheel, the casing 111 and the motor of the shifting device 11 on the drive 1 are not changed without changing the position of the rear wheel. 12. As well as the brake 14, the angle of the installation may have to be adjusted due to space constraints, so as to avoid the obstruction and smooth installation, although the rectangular bearing seat portion 113 at both ends of the output shaft 112 of the driver 1 can be rotated by 90 degrees. The entire actuator 1 can be changed from a vertical shape to a horizontal shape or an inverted shape, but such a position is not necessarily the most ideal direction, and it is also possible to avoid obstacles regardless of the lying position or the vertical upside position. The embarrassing situation that caused the drive 1 to fail to install.

In addition, the two ends of the driver 1 are clamped on the frame 2 by being clamped by the fixing seat 13, but the fixing seat 13 is usually manufactured by punching and pressing, and the precision is low and deformed. Thereafter, the fixing seat 13 and the bearing seat portion 113 are not completely in close contact with each other, resulting in a gap which causes insufficient force to hold the driver 1, so that when the driver 1 drives the electric scooter to travel In addition to the vertical force, longitudinal force and lateral force acting between the road surface and the frame or the vehicle body, the driver 1 also bears the braking torque generated by the brake and its reaction force, so that the driver 1 can withstand repeated vibration and shaking for a long time. Under the action of the force, the driver 1 is prone to loose displacement, vibration and noise.

The reason is that in order to improve the installation of the aforementioned known driver, it is not possible to adjust to a relatively ideal angular position, and problems such as loose displacement and vibration noise are prone to occur, and the present invention provides a drive that allows the driver to select more angular directions and also allows the drive to be driven. More stable being fixed On the frame, there will be no loose displacement and vibration noise.

The technical solution adopted by the present invention to solve the technical problem thereof comprises: a driver mounted on a frame, the driver further comprising a motor provided with a drive on the casing, and the casing is further provided with an indirect drive by the motor. The output shaft, wherein the end faces of the casing at the output shaft form a mounting surface, and the spacing ring on the mounting surface is provided with a plurality of locking holes, and is locked on the frame corresponding to the two mounting surfaces. Two corresponding mounting seats, and at least two perforations are formed in the mounting seat so as to be locked together with the locking holes corresponding to the mounting surface.

Therefore, through the mounting surface provided on the above-mentioned new type of drive and the plurality of locking holes provided in the spacer ring provided on the mounting surface, the locking surface can be locked with the mounting surface by being locked on the frame. The mounting seat allows the drive to be more stable and not loosely fixed on the frame, which not only avoids the occurrence of vibration noise, but also penetrates the locking holes arranged on the mounting surface, so that the driver can select the installation angle according to the requirements. The direction is enabled for the frame of the electric scooter of different designs.

Fig. 6 is a schematic view showing the installation of the electric scooter driver of the present invention at different angular positions on the frame.

Referring to FIG. 3 and FIG. 4, the present electric scooter is equipped with a drive 1 for driving the wheel to drive the electric scooter on the frame 2 at the rear wheel, and the drive 1 includes a shifting device. A differential gear shifting gear set (not shown) is disposed in the casing 111 of the casing 11, and a motor 12 for driving the differential shifting gear set is mounted above the casing 111, and two of the casing 111 are mounted below the casing 111. The end protrudes from the output shaft 112 which is provided for the wheel and is rotated by the differential shifting gear set, and a brake 14 for allowing the electric scooter to stop the brake is installed at the rear end of the motor 12.

The housing 111 of the driver 1 is formed with a mounting surface 114 on the end faces of the two ends of the output shaft 112, and the mounting surface 114 is provided with a plurality of locking holes 115 on the spacer ring, and is installed in the first two. The corresponding frame 15 on the frame 2 corresponding to the surface 114 can be screwed, and the mounting seat 15 is provided with at least two perforations 150 for locking the perforation 150 and the mounting surface 114. The solid hole 115 has a positional correspondence, so that the mounting seat 15 can be locked to the mounting surface 114 by a screw.

Therefore, as shown in FIG. 5, the new type of driver 1 is locked with a mounting seat 15 fixed to the frame 2 through a mounting surface 114 provided thereon to form a gap between the driver 1 and the frame 2. A firm and stable combination eliminates the loose displacement of the actuators 1 and thus avoids the generation of vibration noise.

At the same time, as shown in FIG. 4 and FIG. 6 , a plurality of locking holes 115 arranged on the mounting surface 114 of the driver 1 can be arranged according to the requirements of the actual installation, and the position of the rear wheel of the electric scooter is unchanged. The driver 1 is rotated to an angle that can be prevented from being obstructed, and the number of holes of the locking hole 115 on the mounting surface 114 is determined, and the range of the mounting angle adjustment of the driver 1 can be determined, so that the driver 1 can be suitably installed in various types. Different designs of electric scooters on the frame.
