Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive starter housing technology, and in particular to an automotive starter housing with a shock-resistant structure. Background Technology
[0002] A car starter motor converts electrical energy from a battery into mechanical energy, which drives the engine flywheel to rotate and start the engine. Car starter motors are mainly mounted on the car frame.
[0003] The vibration is mainly caused by the following two reasons: First, since the housing of traditional starters is mostly a rigid metal structure, high-frequency vibrations in the engine compartment are easily transmitted to the internal motor components, leading to problems such as brush wear and rotor eccentricity, thus shortening the service life; Second, when a car travels on a rough and uneven road surface, the bumps will cause impact vibrations, which will damage the connection between the starter and the frame.
[0004] Therefore, it is necessary to design a car starter housing with a shock-resistant structure. Utility Model Content
[0005] To overcome the shortcomings of high-frequency vibrations in the engine compartment being easily transmitted to internal motor components, and the impact vibrations caused by the car bumping when driving on uneven roads, which can damage the connection between the starter motor and the frame, the technical problem to be solved is to provide a car starter housing with a shock-resistant structure.
[0006] The technical solution of this utility model is as follows: a car starter housing with an anti-vibration structure, including a base and a fixed housing, the fixed housing being fixedly connected to the base, and also including a damping rubber layer, an annular honeycomb fixing frame, a starter, a motor end cover and fixing bolts. The fixed housing is filled with a damping rubber layer, and an annular honeycomb fixing frame is provided on the inner side of the damping rubber layer. The starter is installed on the inner side of the annular honeycomb fixing frame, and the motor end cover is fixedly connected to the front side of the starter by fixing bolts.
[0007] As a preferred technical solution of this utility model, it also includes a slide rod, an arc-shaped clamping plate and an elastic element. A set of slide rods is slidably arranged on each side of the fixed housing. An arc-shaped clamping plate is fixedly connected to one end of each set of slide rods inside the fixed housing. The arc-shaped clamping plate clamps the starter motor. An elastic element connects the slide rods and the fixed housing.
[0008] As a preferred technical solution of this utility model, it also includes a support plate, a base plate, a guide seat, a guide rod, and a damping shock absorber. The base plate is provided at the bottom, the base plate is equipped with multiple guide seats, the guide rod is slidably arranged on the guide seats, and multiple damping shock absorbers are connected between the support plate and the base plate.
[0009] As a preferred technical solution of this utility model, two waist-shaped mounting holes are provided on both sides of the base plate.
[0010] As a preferred technical solution of this utility model, it also includes a rubber pad, and a placement groove is provided on the top of the tray. The rubber pad is placed in the placement groove on the top of the tray and is located between the base and the tray.
[0011] As a preferred technical solution of this utility model, each set of sliding rods consists of two rods, which slide horizontally along the fixed outer shell.
[0012] Beneficial effects: When the vibration generated by the engine is transmitted to the starter, the annular honeycomb retainer compresses the damping rubber layer, which converts the mechanical energy of the vibration into heat energy for dissipation. This avoids problems such as brush wear and rotor eccentricity caused by high-frequency vibration in the engine compartment. When the vehicle passes over rough roads, the floor plate compresses the damping shock absorber, causing it to compress and deform, thus isolating and protecting the starter and preventing damage to the connection between the starter and the frame when the vehicle passes over rough roads.

Detailed Implementation
[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Detailed Implementation
[0020] A car starter housing with a shock-resistant structure, see [reference] Figures 1-3As shown, it includes a base 1 and a fixed housing 2. The fixed housing 2 is fixedly connected to the base 1 by welding. It also includes a damping rubber layer 3, an annular honeycomb fixing bracket 4, a starter 5, a motor end cover 6, and fixing bolts 7. The fixed housing 2 is filled with a damping rubber layer 3, which is a silicone-based damping gel layer with a thickness of 2-3mm. The annular honeycomb fixing bracket 4 is set on the inner side of the damping rubber layer 3. The starter 5 is installed on the inner side of the annular honeycomb fixing bracket 4. The motor end cover 6 is fixedly connected to the front of the starter 5 by fixing bolts 7.
[0021] See Figure 1 and Figure 2 As shown, it also includes a slide rod 8, an arc-shaped clamping plate 9, and an elastic element 10. A set of slide rods 8 is slidably arranged on each of the left and right sides of the fixed housing 2. There are two slide rods 8 in each set. The slide rods 8 slide horizontally along the fixed housing 2. The arc-shaped clamping plate 9 is fixedly connected to one end of each set of slide rods 8 inside the fixed housing 2. The arc-shaped clamping plate 9 clamps the starter 5. An elastic element 10 connects the slide rods 8 and the fixed housing 2.
[0022] See Figure 1 and Figure 4 As shown, it also includes a support plate 11, a base plate 12, guide seats 13, guide rods 14, and damping shock absorbers 15. The base 1 has a support plate 11 at the bottom and a placement groove at the top of the support plate 11. A rubber pad 17 is placed in the placement groove at the top of the support plate 11. The rubber pad 17 is located between the base 1 and the support plate 11 and plays a role in vibration isolation for the base 1. The base plate 12 is equipped with eight guide seats 13. Guide rods 14 are slidably arranged on the guide seats 13. Four damping shock absorbers 15 are connected between the support plate 11 and the base plate 12. The four damping shock absorbers 15 are arranged in a rectangular pattern on the base plate 12. Two waist-shaped mounting holes 16 are opened on both sides of the base plate 12. By passing the fixing bolts through the waist-shaped mounting holes 16, it is easy to adjust the installation position of the base plate 12.
[0023] When the vibration generated by the engine is transmitted to the starter 5, the starter 5 presses against the annular honeycomb retainer 4, which in turn presses against the damping rubber layer 3. The damping rubber layer 3 undergoes shear hysteresis deformation, converting the mechanical energy of the vibration into heat energy for dissipation. This absorbs the vibration experienced by the starter 5 during engine operation, preventing problems such as brush wear and rotor eccentricity caused by high-frequency vibrations in the engine compartment. Through the slide bar 8, the arc-shaped clamp 9, and the elastic element 10, the starter 5 is fixed to the housing 2. The internal structure remains relatively centered, and the rotor of the starter 5 is eccentric. When the vehicle passes over a rough road, the low-frequency, high-amplitude impact generated by the vehicle is transmitted to the base plate 12 through the frame. The base plate 12 drives the guide rod 14 to slide axially along the guide seat 13. At the same time, the base plate 12 squeezes the damping shock absorber 15, causing the damping shock absorber 15 to compress and deform, thereby absorbing and consuming more than 60% of the impact kinetic energy, thus playing a role in vibration isolation and protection for the starter 5, and preventing damage to the connection between the starter 5 and the frame when the vehicle passes over a rough road.
