Description

Technical Field

[0001] This utility model relates to the field of automotive generator technology, and more specifically, to an automotive generator with shock-resistant stiffness. Background Technology

[0002] A car generator with shock-resistant stiffness refers to a generator whose structure is specially designed and reinforced to withstand the continuous vibration and impact generated during vehicle operation, thereby ensuring long-term stable and reliable operation. For example, the car generator with shock-resistant stiffness proposed in publication number "CN222215387U" includes a base, with grooves on both the left and right sides of the base. A slider is slidably connected to the inner wall of the groove, and a connecting post is fixedly connected to the side surface of the slider. A spring is sleeved on the outer surface of the connecting post. A first limiting frame is fixedly connected to the end of the connecting post in the left groove away from the slider. A second limiting frame is slidably connected inside the base, and the second limiting frame is connected to the connecting post in the right groove. Rubber pads are fixedly connected to the inner walls of both the first and second limiting frames. However, in the above technical solution, the anti-vibration structure of the automobile generator mainly relies on the first and second limit frames and rubber pads set laterally, and achieves the lateral shock absorption function through the slide groove, slider and spring. It does not have an axial anti-vibration and buffer structure. As a result, if the generator is subjected to axial impact or vibration during vehicle operation, it cannot effectively absorb and disperse the vibration energy in that direction, which can easily cause premature wear or damage to key components such as bearings and rotor inside the generator, affecting the service life and operational stability of the generator. Utility Model Content

[0003] The main purpose of this utility model is to provide an automotive generator with anti-vibration stiffness, which can effectively solve the problem that the anti-vibration structure of automotive generators in the background technology mainly relies on the first and second limit frames and rubber pads set laterally, and achieves lateral shock absorption through grooves, sliders and springs. However, it does not have an axial anti-vibration and buffering structure. As a result, if the generator is subjected to axial impact or vibration during vehicle operation, it cannot effectively absorb and disperse the vibration energy in that direction, which can easily cause premature wear or damage to key components such as bearings and rotors inside the generator, affecting the service life and operational stability of the generator.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A car generator with shock-resistant rigidity includes a base, an arc-shaped groove on the upper surface of the base, a first rubber pad at the bottom of the arc-shaped groove, limit frames fixedly installed on both sides of the base by tightening bolts, the two limit frames being fixedly connected by limit bolts and limit nuts, and a second rubber pad being provided on the opposite side of the two limit frames. Both sides of the base are provided with through grooves, one end of each through groove is connected to the inside of the arc groove, and a top plate is movably arranged in each of the two through grooves. A first rubber plate is fixedly installed on the opposite side of each of the two top plates. Both of the limiting frames have through-holes on both sides, and each of the two limiting frames has a movable plate movably disposed in each of the two connecting slots. Each of the two movable plates has a second rubber plate disposed on one side. The generator body is installed inside the arc-shaped groove.

[0005] Preferably, the base has a through-hole groove on one side, and mounting plates are fixedly installed on both sides of the bottom of the mounting groove. A bidirectional screw is rotatably installed between the two mounting plates, and support plates are threaded on both sides of the bidirectional screw. Two rectangular slots are formed on both sides of the bottom of the mounting slot. A support block is slidably arranged in each rectangular slot. The upper surface of each support block is fixedly connected to the corresponding top plate, and the lower surface of each support block is fixedly connected to the corresponding support plate.

[0006] Preferably, a guide rod is fixedly installed between the two mounting plates, and the two support plates are slidably disposed on both sides of the guide rod.

[0007] Preferably, one of the mounting plates has a mounting hole on one side surface, one end of the bidirectional lead screw extends into the mounting hole and is fixedly mounted with a rotating block, one side surface of the rotating block has a hexagonal groove, and a rubber ring is fixedly mounted on the inner wall of the mounting hole.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-8As shown, a car generator with shock-resistant rigidity includes a base 1. An arc-shaped groove 2 is provided on the upper surface of the base 1. A first rubber pad is provided at the bottom of the arc-shaped groove 2. Limiting brackets 4 are fixedly installed on both sides of the base 1 by tightening bolts 3. The two limiting brackets 4 are fixedly connected to the limiting nuts 6 by limiting bolts 5. A second rubber pad is provided on the opposite side of the two limiting brackets 4. Both sides of the base 1 have through grooves 7, one end of each through groove 7 is connected to the inside of the arc groove 2, and a top plate 8 is movably installed in each of the two through grooves 7. A first rubber plate 9 is fixedly installed on the opposite side of each of the two top plates 8. Both sides of the two limiting frames 4 are provided with connecting grooves 10, and each connecting groove 10 is movably provided with a movable plate 11. Each movable plate 11 is provided with a second rubber plate 12 on one side. The generator body 13 is installed inside the arc-shaped groove 2.

[0015] A mounting groove 14 is provided through one side of the base 1. Mounting plates 15 are fixedly installed on both sides of the bottom of the mounting groove 14. A two-way screw 16 is rotatably installed between the two mounting plates 15. Support plates 17 are threaded on both sides of the two-way screw 16. Two rectangular slots 1401 are provided on both sides of the bottom of the mounting slot 14. A support block 1402 is slidably arranged in each rectangular slot 1401. The upper surface of each support block 1402 is fixedly connected to the corresponding top plate 8, and the lower surface of each support block 1402 is fixedly connected to the corresponding support plate 17.

[0016] A guide rod 18 is fixedly installed between two mounting plates 15, and two support plates 17 are slidably arranged on both sides of the guide rod 18.

[0017] First, the generator body 13 is placed in the arc-shaped groove 2 of the base 1, with its bottom supported by the first rubber pad, completing the initial positioning and bottom buffering. Then, two limit brackets 4 are placed on both sides of the base 1 and initially fixed with the tightening bolts 3. The two limit brackets 4 are then fastened together with the limit bolts 5 and the limit nuts 6, so that the second rubber pad on its inner side fits tightly against the outer shell of the generator body 13, thereby achieving effective clamping and vibration reduction of the generator in the lateral direction. Next, by rotating the bidirectional lead screw 16, the two support plates 17 are driven to move towards each other along the guide rod 18. The support plates 17 drive the support block 1402 to slide in the rectangular groove 1401, thereby pushing the top plate 8 and the first rubber plate 9 to move towards the end of the generator body 13 in the through groove 7 until the first rubber plate 9 elastically contacts the end face of the generator body 13 and applies an appropriate preload, providing axial buffering and support for the generator, effectively overcoming the defect of traditional generators lacking axial buffering, and significantly improving the ability to suppress multi-directional vibration.

[0018] In another embodiment of the present invention, a mounting hole 19 is provided on one side surface of one of the mounting plates 15, one end of the bidirectional lead screw 16 extends into the mounting hole 19 and is fixedly mounted with a rotating block 20, a hexagonal groove 21 is provided on one side surface of the rotating block 20, and a rubber ring 22 is fixedly mounted on the inner wall of the mounting hole 19.

[0019] When it is necessary to adjust the double-acting screw 16 to change the axial preload, the operator can use a standard hex wrench inserted into the hexagonal slot 21 of the rotating block 20. The rubber ring 22 maintains elastic contact with the outer surface of the rotating block 20, providing appropriate rotational damping. When the wrench is turned, the rotating block 20 drives the double-acting screw 16 to rotate smoothly in the mounting plate 15, driving the two side support plates 17 to move synchronously in opposite directions along the guide rod 18, thereby precisely adjusting the axial clamping force of the top plate 8 on the generator body 13. After adjustment, the wrench is removed. The damping effect of the rubber ring 22 can, to a certain extent, prevent the rotating block 20 from rotating unexpectedly due to vehicle vibration, helping to maintain the stability of the preload.

[0020] In another embodiment of this utility model, two support grooves 23 are provided through the top surface of the two through grooves 7. A connecting frame 24 is movably arranged in each support groove 23. The two ends of each connecting frame 24 are fixedly connected to the corresponding top plate 8 and movable plate 11 by fastening bolts 25.

[0021] When it is necessary to disassemble or install the limit bracket 4, the operator can first loosen and remove the fastening bolts 25 at both ends of the connecting bracket 24. At this time, the connecting bracket 24 can move or be removed in the support groove 23, thereby releasing the rigid connection between the top plate 8 and the moving plate 11. Subsequently, the limit bracket 4 can be moved out from the side of the generator body 13 or installed without obstruction. After the limit bracket 4 is in place, the connecting bracket 24 is reinstalled and the fastening bolts 25 are tightened to restore the linkage relationship between the top plate 8 and the moving plate 11, ensuring the integrity of the structure.

[0022] In another embodiment of this utility model, several heat dissipation grooves 26 are provided on the outer wall surfaces of both limiting frames 4.

[0023] During operation, the heat generated by the generator body 13 is transferred to the limiting frame 4 in contact with it. Several heat dissipation grooves 26 are provided on the outer surface of the limiting frame 4, effectively increasing the contact area between the limiting frame 4 and the surrounding air. As air flows through the heat dissipation grooves 26, it can more efficiently carry away the heat from the limiting frame 4, thereby accelerating the heat dissipation process of the generator body 13.

[0024] The working principle of this type of car generator with shock-resistant stiffness: During operation, the generator body 13 is placed in the arc-shaped groove 2 of the base 1, with its bottom supported by the first rubber pad, completing the initial positioning and bottom buffering. Then, two limit brackets 4 are placed on both sides of the base 1 and initially fixed with the tightening bolts 3. The two limit brackets 4 are then fastened together with the limit bolts 5 and the limit nuts 6, so that the second rubber pad on its inner side fits tightly against the outer shell of the generator body 13, thereby achieving effective clamping and vibration reduction of the generator in the lateral direction. Next, by rotating the bidirectional lead screw 16, the two support plates 17 are driven to move towards each other along the guide rod 18. The support plates 17 drive the support block 1402 to slide in the rectangular groove 1401, thereby pushing the top plate 8 and the first rubber plate 9 to move towards the end of the generator body 13 in the through groove 7 until the first rubber plate 9 elastically contacts the end face of the generator body 13 and applies an appropriate preload, providing axial buffering and support for the generator, effectively overcoming the defect of traditional generators lacking axial buffering, and significantly improving the ability to suppress multi-directional vibration.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
