Technical Field

[0001] This utility model relates to the field of automotive engine installation technology, specifically to an engine installation structure for new energy vehicles. Background Technology

[0002] With the development of the times, new energy electric vehicles have gradually appeared in people's field of vision. New energy vehicles are divided into many types, the most common being pure electric drive and plug-in hybrid. Plug-in hybrid vehicles are composed of an engine and an electric motor.

[0003] An engine mounting bracket is an important component of a car engine. Its main function is to support and secure the engine and reduce vibrations generated during engine operation, thereby improving vehicle comfort and engine lifespan. Conventional engine mounting brackets directly connect the engine to the engine compartment frame. However, the engine will shake when starting, and excessive shaking will cause the car to vibrate, affecting the user's comfort. Summary of the Invention

The bottom of each connector A has an integrally fixed fixing shaft.

[0008] Preferably, there are multiple telescopic rods A. Each telescopic rod A is fitted onto the bottom of the fixed shaft and rotatably connected to the connector A, so as to realize the lateral rotation of the telescopic rod A and the connector A.

Each telescopic rod B has a connector B at its bottom. One end of the connector B is rotatably connected to the telescopic rod B, so as to realize the longitudinal rotation of the connector B and the telescopic rod B.

[0009] Preferably, the bracket is located inside the engine mounting bracket point, the other end of the connector B is attached to the bottom of the bracket and fixed by screws, the cover is located at the bottom of the bracket, there is a support rod between the bracket and the cover, the upper and lower ends of the support rod are fixedly connected to the bracket and the cover respectively, and the high-strength spring is located inside the engine mounting bracket, the upper and lower ends of the high-strength spring abut against the cover and the engine mounting bracket respectively.

[0010] Preferably, the bottom of the support rod is fastened to the top of the high-strength spring. This method can restrict the high-strength spring and prevent it from shifting.

[0011] Preferably, the bracket has a connecting frame at the top, and each of the upper and lower ends of the connecting frame has an integrally fixed hexagonal fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model involves mounting the bottom of the mounting plate onto the engine compartment frame of the car and securing it with bolts. Then, the top of the connecting bracket is mounted on the bottom of the engine and connected to the engine via the connecting bracket. When the engine starts and generates vibrations, the vibrations from the bottom of the engine are transmitted to the bracket via the connecting bracket. When the bracket is impacted, a high-strength spring provides shock absorption, thereby reducing vehicle vibration caused by engine vibration. Furthermore, during the high-strength spring's damping action, the outer telescopic rods B and A extend and retract rapidly. The six telescopic rods A and B can be linked together during the multi-directional swing of the high-strength spring. This limits the distance of telescopic rod A when it extends and retracts within telescopic rod B, restricting the swing amplitude of the high-strength spring and preventing excessive engine shaking.

[0026] Furthermore, the top of the engine mounting bracket 100 has multiple integrally fixed support brackets 101, and each support bracket 101 has two integrally fixed fixing blocks 102 on both sides of its top. There are multiple connectors A200, and one connector A200 is embedded between every two engine mounting brackets 100. The two ends of the connector A200 pass through the fixing blocks 102 and are rotatably connected to them, so as to realize the longitudinal rotation of the connector A200 and the fixing blocks 102. The bottom of each connector A200 has an integrally fixed fixing shaft 201.

[0027] Furthermore, there are multiple telescopic rods A202. Each telescopic rod A202 is fitted onto the bottom of the fixed shaft 201 and is rotatably connected to the connector A200, enabling the telescopic rod A202 and the connector A200 to rotate laterally. The telescopic rod B203 is fitted onto the outside of the telescopic rod A202, enabling the telescopic rod B203 to slide and connect with the telescopic rod A202, thereby adjusting the total length of the connection between the two. Each telescopic rod B203 has a connector B204 at its bottom. One end of the connector B204 is rotatably connected to the telescopic rod B203, enabling the connector B204 and the telescopic rod B203 to rotate longitudinally.

[0028] Furthermore, the bracket 300 is located inside the engine mounting bracket 100. The other end of the connector B204 is attached to the bottom of the bracket 300 and is fixed by screws. The retainer 302 is located at the bottom of the bracket 300. There is a support rod 301 between the bracket 300 and the retainer 302. The upper and lower ends of the support rod 301 are fixedly connected to the bracket 300 and the retainer 302, respectively. The high-strength spring 400 is located inside the engine mounting bracket 100. The upper and lower ends of the high-strength spring 400 abut against the retainer 302 and the engine mounting bracket 100, respectively.

[0029] Furthermore, the bottom of the support rod 301 is fastened to the top of the high-strength spring 400. In this way, the high-strength spring 400 can be restricted and prevented from shifting.

[0030] Furthermore, the top of the bracket 300 has a connecting frame 600, and each of the upper and lower ends of the connecting frame 600 has an integrally fixed hexagonal fixing plate. The fixing plate at the bottom of the connecting frame 600 is fixedly connected to the top of the bracket 300, and the fixing plate at the top of the connecting frame 600 has a mounting hole.

[0031] Furthermore, the engine mounting bracket 100 has a hexagonal structure, with each corner of the hexagon serving as a support point, resulting in higher structural strength. Additionally, there is a spacing between each support point to facilitate the installation of various components.

[0032] Furthermore, the bottom of the engine mounting bracket 100 has a mounting plate 500, the bottom of the engine mounting bracket 100 is welded and fixed to the mounting plate 500, and the mounting plate 500 has multiple mounting holes, and the mounting plate 500 is mounted on the car engine compartment frame.

[0033] Working principle: In use, the bottom of the mounting plate 500 is installed on the car engine compartment frame and secured with bolts. Then, the top of the connecting bracket 600 is installed on the bottom of the engine and connected to the engine through the connecting bracket 600. When the engine starts and generates vibration, the bottom of the engine transmits the vibration to the bracket 300 through the connecting bracket 600. When the bracket 300 is impacted, the high-strength spring 400 provides shock absorption, thereby reducing the body vibration caused by engine vibration. When the high-strength spring 400 is providing shock absorption, the outer telescopic rods B203 and A202 extend and retract quickly. The six telescopic rods A202 and B203 can be linked when the high-strength spring 400 swings in multiple directions. Thus, the telescopic rod A202 has a distance limit when it extends and retracts inside the telescopic rod B203, which can limit the swing amplitude of the high-strength spring 400 and prevent excessive shaking of the engine itself.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
