Description

Technical Field

[0001] The invention relates to the technical field of engine brackets, and in particular to an engine bracket device with an energy recovery function. Background Art

[0002] Currently, the vibrations of the automotive powertrain are absorbed by the engine mounts to limit their impact on driver and passenger comfort, thus wasting the energy generated by the powertrain movement. When the engine is running, internal forces and torques generated by the crankshaft are generated. These forces cause vibrations to be transmitted to the engine mounts. In order to limit the negative impact of NHV on passenger comfort, typical engine mounts include rubber elements or hydraulic damping systems. The damping elements inside the engine mounts limit the vibrations of the engine. This means that the energy of the vibrations is converted into heat and then dissipated into the atmosphere and lost. There is an urgent need in the prior art for an engine mount device with energy recovery function.

[0003] Patent document CN105790542A discloses an electromagnetic retarder with energy recovery function, including a stator, a rotor, a power electronic module and a transmission shaft, the power electronic module is connected to the rotor through a reversing valve, and is characterized in that: the rotor is placed in the stator, and a gap is left between the rotor and the stator; the stator includes a stator bracket, a generating armature, a liquid cooling isolation module and a cylinder carrying eddy currents, and the stator bracket is connected to the transmission shaft through a bearing; the liquid cooling isolation module is placed between the generating armature and the cylinder; the generating armature includes a generating armature winding and a generating armature core, and the generating armature is connected to the stator bracket; the rotor includes a rotor bracket, an excitation winding and an excitation core, and the rotor bracket is connected to the transmission shaft, and the rotor bracket is connected to the excitation winding. This patent still has room for improvement in structure and performance, and the patent cannot be well applied to the engine bracket. Summary of the invention

[0004] In view of the defects in the prior art, an object of the present invention is to provide an engine bracket device with energy recovery function.

[0050] Example 1

[0051] An engine support device with energy recovery function comprises: a lever mechanism 1, similar to a pushrod / pullrod suspension, one side of which is connected to a cylinder head 2 of an engine 3 and the other side is connected to a linear generator;

[0057] The amount of travel depends on the rocker ratio, b / c, and the location of the mechanism's pivot point, which will be fine-tuned for optimum generator performance.

[0058] Example 2

[0059] An engine support device with energy recovery function also includes a linear generator 13, but with a shorter stroke and is directly bolted to the cylinder head 2. Due to the small number of parts, this solution will have a simpler structure, which will reduce friction losses, complexity, and facilitate the selection of layout solutions.

[0067] The engine rests on two engine mounts 11, which support the weight of the engine but allow some rocking, acting like fulcrums for the entire engine.

[0068] Vehicle application range

[0070] The power generating bracket may also be used in different applications where similar parasitic losses occur, such as other parts of the powertrain, such as the transmission housing 18 and the differential housing 19. This depends on the layout of the vehicle powertrain.

An engine support device with energy recovery function can be realized by using an additional component that acts as a spring. For example, a leaf spring mounted on the cylinder head 2, made of a lightweight composite material; 20 or a coil spring 21 inside the power generation device.
