Description

Technical Field

[0001] This utility model relates to the field of automotive engine housing technology, specifically to an automotive engine housing with shock absorption function. Background Technology

[0002] The car engine is the core device that provides power to a car. It is responsible for converting the chemical energy of fuel into mechanical energy and directly affects the vehicle's power, economy, and environmental performance. The car engine casing is the shell structure that supports the car engine.

[0003] For example, announcement number CN206694497U (titled "An Automobile Engine Housing with Shock Absorption Function") includes an engine housing and a shock-absorbing block. The engine housing has an oil passage hole inside. A buffer block is fixedly connected to the lower surface of the engine housing. The buffer block has a first buffer cavity and a first sliding hole inside. The inner top wall of the first buffer cavity communicates with one end of the oil passage hole, and the inner bottom wall of the first buffer cavity communicates with the top of the first sliding hole. A first positioning block is slidably connected to the inner wall of the first buffer cavity. A first buffer post is fixedly connected to the surface of the first positioning block, and the surface of the first buffer post is... The inner wall of the first sliding hole is slidably connected, and the bottom end of the first buffer column extends to the bottom of the first sliding hole. A buffer plate is fixedly connected to the bottom end of the first buffer column. By setting the surface of the first buffer column to slide and connect with the inner wall of the first sliding hole, the bottom end of the engine housing is damped. The first buffer column pushes the hydraulic oil in the first buffer chamber to compress and flow, thereby achieving the effect of shock absorption and vibration resistance. The inner wall of the second sliding hole is slidably connected with the left buffer column and the right buffer column respectively, achieving the effect of shock absorption and vibration resistance on the surface of the engine housing. The buffer spring can keep the left buffer column and the right buffer column in a damping state at all times.

[0004] The aforementioned car engine housing uses an external shock-absorbing mechanism to buffer and dampen the car engine inside the housing. However, installing a shock-absorbing mechanism on the housing increases the space occupied by the housing and makes it prone to damage, causing inconvenience in the installation of the car engine housing and affecting its service life. Therefore, we provide a car engine housing with shock-absorbing function. Utility Model Content

[0005] The purpose of this utility model is to provide a car engine housing with shock absorption function, so as to solve the problem mentioned in the background art that the existing car engine housing uses an external shock absorption mechanism to buffer and absorb the car engine inside the housing. However, setting a shock absorption mechanism on the housing will increase the space occupied by the housing and is prone to damage, causing inconvenience in the installation of the car engine housing and affecting its service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a car engine housing with shock absorption function, including a main housing frame, an extension frame integrally formed at the upper end of the main housing frame, two limiting top plates installed on the inner wall of the extension frame, and threaded through holes provided at the inner center of the two limiting top plates.

[0007] Also includes:

[0008] The limiting screw is movably disposed inside the two threaded holes, and a damping damper and a throttle are respectively welded to both ends of the limiting screw. The size of the damping damper and the throttle is larger than the diameter of the threaded holes.

[0009] Spring shock absorbers are welded inside the main frame of the outer shell. There are four spring shock absorbers, and movable seats are welded to the upper ends of the four spring shock absorbers. A lifting seat plate is installed above the movable seat plate, and ventilation mounting holes are provided inside the lifting seat plate.

[0010] The bottom groove is located at the center of the bottom of the main frame of the outer shell, and the inside of the bottom groove is provided with ventilation holes.

[0011] Preferably, the movable carrier is provided with bearing grooves on both outer walls, and auxiliary rollers are rotatably arranged inside the bearing grooves through a connecting shaft. The movable carrier is rolledly connected to the inner wall of the outer shell main frame through the auxiliary rollers.

[0012] Preferably, four connecting rods are provided between the movable carrier and the lifting seat plate, and the two ends of the connecting rods are welded to the movable carrier and the lifting seat plate respectively.

[0013] Preferably, shock-absorbing strips are provided at all four ends of the inner wall of the main frame of the outer shell, and the shock-absorbing strips are fixedly connected to the inner wall of the main frame of the outer shell by nail-free adhesive.

[0014] Preferably, ventilation holes are provided on both outer walls of the main frame of the outer shell, and ventilation slots are provided on both sides of the bottom groove. The bottom groove and ventilation slots are integral with the main frame of the outer shell.

[0015] Preferably, mounting grooves are provided on the bottom outer walls of both sides of the main frame of the outer shell, and two bolt holes are provided inside each mounting groove.

[0016] Preferably, two fastening bolts are provided at the connection positions between the two ends of the limiting top plate and the extension frame, and the limiting top plate is fixedly connected to the extension frame by the fastening bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention installs two limiting top plates onto the inner wall of an extended frame, and rotates the throttle to drive the limiting screw downwards, causing the damping shock absorber to abut against the car engine hood. This achieves top-level limiting and shock absorption of the car engine. Four spring shock absorbers at the bottom support the movable carrier, providing bottom-level support and shock absorption for the car engine. The shock absorption mechanisms are all located inside the car engine housing, overcoming the problems of existing car engine housings using external shock absorption mechanisms to buffer and absorb shocks from the car engine inside the housing. However, setting shock absorption mechanisms on the housing increases the space occupied by the housing and makes it prone to damage, causing inconvenience in the installation of the car engine housing and affecting its service life.
