Description

Technical Field

[0001] This utility model relates to an electric motor, specifically to a nut with an adjustable mounting width applied to the electric motor. Background Technology

[0002] Existing methods for fixing mid-drive motors all use fixed mounting thread holes or fixed mounting holes, which cannot adjust the width of the mounting holes according to the actual situation.

[0003] like Figure 1 and Figure 2 As shown, the motor has fixed mounting holes and is locked to the frame using screws and nuts. Judging from the given dimensions, the tolerance requirements for the frame machining are very high. If the frame machining dimensions are too small, it cannot be installed. If the machining dimensions are too large, the screws will deform the frame when locking. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nut with adjustable installation width for use on motors, so as to solve the problems existing in the background art.

[0005] This utility model applies to an adjustable mounting width nut on a motor and the motor itself, and is achieved through the following technical solution, including a nut assembly mounted on the motor body;

[0006] One side of the motor body is a mounting and positioning surface, and the mounting and positioning surface is provided with threaded holes for fixing; the other side of the motor body is an adjustment and positioning surface, and the adjustment and positioning surface is provided with an adjustment groove; the nut assembly is slidably installed in the mounting groove.

[0007] As a preferred technical solution, the nut assembly includes a slide nut and a cotter pin:

[0008] The slide nut has a notch on one side and slides within the mounting groove; the cotter pin is located at the notch of the slide nut, and by pressing in the cotter pin, the slide nut can be fixed at any position within the mounting groove.

[0009] As a preferred technical solution, the mounting and positioning surface of the motor body corresponds to the fixing surface on one side of the frame and is fixed by screws.

[0010] As a preferred technical solution, the adjustment and positioning surface of the motor body corresponds to the fixed surface on the other side of the frame. By adjusting the position of the slide nut in the mounting groove, it is adapted to the fixed surface on the other side of the frame to fill the excess width, and is threadedly connected to the slide nut by tightening screws.

[0011] The beneficial effects of this utility model are:

[0012] The width of the motor mounting hole of this utility model can be adjusted according to the actual situation of the vehicle frame. When the motor mounting position is wide, the slide nut can slide out part of it to fill the excess width, making it more widely applicable. Attached Figure Description

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] like Figures 3-5 As shown, this utility model provides an adjustable mounting width nut for use on a motor, comprising a nut assembly mounted on the motor body 1.

[0021] One side of the motor body 1 is a mounting and positioning surface 6, and the mounting and positioning surface 6 is provided with threaded holes 5 for fixing; the other side of the motor body 1 is an adjustment and positioning surface 7, and the adjustment and positioning surface 7 is provided with an adjustment groove 3; the nut assembly is slidably installed in the mounting groove 3.

[0022] To facilitate the adjustment of the slide nut, in this embodiment, the nut assembly includes a slide nut 2 and a cotter pin 4:

[0023] The slide nut 2 has a notch on one side and slides within the mounting groove 3; the cotter pin 4 is located at the notch of the slide nut 2, and the slide nut 2 can be fixed at any position in the mounting groove 3 by pressing in the cotter pin 4.

[0024] To facilitate the fixing of the motor body on one side, in this embodiment, the mounting and positioning surface 6 of the motor body 1 corresponds to the fixing surface on one side of the frame and is fixed by screws.

[0025] To facilitate the adjustment and installation of the motor body, in this embodiment, the adjustment positioning surface 7 of the motor body 1 corresponds to the fixed surface on the other side of the frame. By adjusting the position of the slide nut 2 in the mounting groove 3, it is adapted to fit the fixed surface on the other side of the frame to fill the excess width, and is threadedly connected to the slide nut 2 by tightening screws.

[0026] The sliding nut of this invention can slide within a limited range in the mounting groove of the motor body. The sliding nut and the motor housing slide together and are fixed by pressing in a cotter pin. When the installation position of the mid-mounted motor is relatively wide, the sliding nut can slide out a portion to fill the excess width.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
