Description

Suspension type anti-drop motor middle cover mechanism and trolley driving device Technical Field The utility model belongs to the technical field of installation of driving parts of new energy automobiles, and particularly relates to a suspension type anti-drop motor middle cover mechanism and an electric car driving device. Background In recent years, new energy vehicles are rapidly developed, and the demand for electrically driven engineering machinery vehicles is increasing, and the conventional engine and gearbox power transmission route is gradually replaced by a route represented by a motor and a gearbox. The existing motor is usually arranged independently and is fixed by using bolts only, but the bolts are easy to loosen or even fall off under the frequent vibration working condition or after long-term use, so that the motor falls. The independent arrangement of the motor and the gearbox in the prior art causes the dispersion of the structure, low compactness, large occupied space and inconvenience for the arrangement and maintenance of the whole machine, and if the number of bolts is simply increased or the anti-loose gaskets are increased, the installation complexity is increased. Therefore, it is necessary for the person skilled in the art to solve the above-mentioned problems. Disclosure of utility model The utility model provides a suspension type anti-drop motor middle cover mechanism, which mainly solves the problems that in the prior art, a motor is singly fixed relative to a gearbox and is easy to drop and damage in a vibration environment, and meanwhile, the installation occupation space of the motor in the prior art is greatly unfavorable for the arrangement and maintenance of a complete machine. Another aspect of the present utility model also provides an electric car driving device. In order to achieve the above purpose, the utility model adopts the following technical scheme: a suspended anti-drop motor middle cover mechanism, comprising: the first bracket is provided with a first mounting ring seat; The second bracket is detachably connected with the first bracket, and a second installation position is arranged on the second bracket; The first support with dismantle the connection between the second support, wherein, first support with set up the protruding structure of card between the second support, the protruding structure of card including set up in first draw-in groove on the first support with set up in first fixture block on the second support, or set up in first fixture block of first support or set up in first draw-in groove on the second support, first fixture block with first draw-in groove adaptation, first fixture block joint in the first draw-in groove.
