Description

Technical Field

[0001] This utility model relates to the field of automotive structural components technology, specifically to a rear cover heat dissipation assembly for an automotive generator. Background Technology

[0002] The automotive alternator is the main power source for a vehicle's electrical system, responsible for converting mechanical energy into electrical energy to power the vehicle's electrical equipment and battery. It mainly consists of a rotor, stator, rectifier, and end caps. When the car engine starts, the alternator drives the rotor to rotate via belt drive. The magnetic field on the rotor interacts with the coils on the stator to generate alternating current (AC). The rectifier then converts the AC current into direct current (DC), providing a stable power supply to the vehicle's electrical system.

[0003] The rear cover cooling system of a car alternator mainly includes vents and a fan. The alternator generates a significant amount of heat during operation. The vents are located on the top or side of the rear cover, and cooling is achieved through natural convection or a fan to ensure the internal temperature of the alternator does not become excessively high.

[0004] Conventional automotive alternators typically have a relatively complex rear cover with multiple heat dissipation structures, and they generally employ a relatively fixed structural design, which limits the ease of ventilation, heat dissipation, and disassembly / maintenance.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a rear cover heat dissipation component for automobile generators. Utility Model Content

[0006] The purpose of this invention is to provide a rear cover heat dissipation assembly for an automotive generator to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rear cover heat dissipation assembly for an automotive generator, comprising a connecting frame and an assembly frame, wherein an assembly frame is installed on one side of the connecting frame, and a silent fan is installed in the middle of the interior of the assembly frame, and a protective frame is connected to the side of the assembly frame away from the assembly frame; the connecting frame comprises a main frame body, a docking groove and a docking insertion hole, wherein a docking groove is provided on one side of the main frame body, and a docking insertion hole is provided on the side of the main frame body away from the docking groove.

[0008] Furthermore, the assembly frame includes an assembly tube frame, a support frame, a stabilizing frame, and a docking pile. The support frame is connected to one side of the assembly tube frame, and a stabilizing frame is installed at one end inside the assembly tube frame. A docking pile is provided at the end of the assembly tube frame away from the support frame.

[0009] Furthermore, the support frame and the assembly pipe frame are fixedly connected and are erected between the support frame and the stabilizing frame, and the docking piles are arranged in a ring array structure with the assembly pipe frame as the center.

[0010] Furthermore, the docking pile and the assembly pipe frame are integrated into one structure, and the surface structure of the docking groove matches the surface structure of the docking pile.

[0011] Furthermore, the connecting frame and the assembly frame are connected and fixed by bolts, and the connecting frame is made of damping alloy material.

[0012] Furthermore, the protective frame includes a support frame, support posts, buffer rods, and a buffer frame. The support posts are connected to the edge of the support frame, and the buffer rods are connected to the side of the support frame near the connecting frame. The buffer frames are also connected to the surface of the buffer rods.

[0013] Furthermore, the inner surface structure of the docking hole matches the outer surface structure of one end of the buffer rod, and the buffer frames are equidistantly arranged on the surface of the buffer rod and fixedly connected to each other. In addition, the buffer rod is provided with four sets of bolts that are connected and fixed to the docking piles.

[0014] Furthermore, the protective frame is made of the same material as the connecting frame, and the protective frame and the connecting frame are connected to each other by an insertion structure.

[0015] This utility model provides a rear cover heat dissipation assembly for an automotive alternator, which has the following beneficial effects:

[0016] 1. This utility model incorporates a connecting frame, the entire connecting frame being made of damping alloy material. Utilizing the material's properties, it rapidly converts vibration energy into heat energy, resulting in rapid attenuation. The protective frame is also made of the same material. This allows for the conduction, absorption, and further attenuation of structural vibrations generated during the operation of the car generator and the silent fan inside the assembly frame, thus achieving excellent vibration reduction and noise reduction. Furthermore, the main frame has docking slots and docking holes on both sides, which, in conjunction with bolt connections and the insertion and assembly of the structures, allow the assembly frame and protective frame to be installed on both sides of the connecting frame. The use of this structure provides good structural combination and connection strength and stability between the device structures, while also allowing for good structural disassembly, facilitating maintenance of the device structure.

[0017] 2. This utility model, by connecting a protective frame to one side of the connecting frame, and by using multiple sets of support piles to connect multiple sets of buffer rods on one side of the support frame, forms a relatively dense frame structure. By using the combination of the above structures, it can provide effective structural anti-collision protection without affecting the ventilation and heat dissipation of the car generator inside the protective frame. At the same time, the use of the frame structure can make the entire device structure lighter to a certain extent. In addition, by setting multiple sets of support piles on the edge of the support frame, and using bolts, the entire device structure can be fixed to the outside of the car generator and maintain sufficient connection firmness.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 4As shown, a rear cover heat dissipation assembly for an automotive alternator includes a connecting frame 1 and an assembly frame 2. The assembly frame 2 is mounted on one side of the connecting frame 1, and a silent fan 3 is installed in the middle of the interior of the assembly frame 2. A protective frame 4 is connected to the side of the assembly frame 2 away from the assembly frame 2. The connecting frame 1 includes a main frame body 101, a docking groove 102, and a docking insertion hole 103. The docking groove 102 is provided on one side of the main frame body 101, and the docking insertion hole 103 is provided on the side of the main frame body 101 away from the docking groove 102. The assembly frame 2 includes an assembly tube frame 201, a support frame 202, a stabilizing frame 203, and a docking post 204. The support frame 202 is connected to one side of the assembly tube frame 201, and a silent fan 3 is installed at one end of the interior of the assembly tube frame 201. The stabilizing frame 203, and the assembly tube frame 201 is provided with a docking pile 204 at the end away from the support frame 202. The support frame 202 and the assembly tube frame 201 are fixedly connected and are erected between the support frame 202 and the stabilizing frame 203. The docking piles 204 are arranged in a ring array structure with the assembly tube frame 201 as the center. The docking piles 204 and the assembly tube frame 201 are integrated. The surface structure of the docking groove 102 matches the surface structure of the docking pile 204. The two sides of the main frame 101 are respectively provided with docking grooves 102 and docking holes 103. With the connection of bolts and the joint assembly of the structures, the assembly frame 2 and the protective frame 4 are respectively installed on both sides of the connecting frame 1.

[0025] like Figures 1 to 4 As shown, the connecting frame 1 and the assembly frame 2 are connected and fixed by bolts. The connecting frame 1 is made of damping alloy material. The protective frame 4 includes a support frame 401, a support post 402, a buffer rod 403, and a buffer frame 404. The support post 402 is connected to the edge of the support frame 401, and the buffer rod 403 is connected to the side of the support frame 401 near the connecting frame 1. The buffer frame 404 is connected to the surface of the buffer rod 403. The inner surface structure of the mating hole 103 matches the outer surface structure of one end of the buffer rod 403, and the buffer frames 404 are equidistantly arranged on the buffer rod 403. The surfaces are fixedly connected to each other, and the buffer rod 403 is provided with four sets of bolts and connected to the connecting pile 204. The protective frame 4 is made of the same material as the connecting frame 1, and the protective frame 4 and the connecting frame 1 are connected to each other by an insertion structure. On one side of the support frame 401, multiple sets of support piles 402 are used to connect multiple sets of buffer rods 403, thereby forming a relatively dense frame structure. In addition, by providing multiple sets of support piles 402 on the edge of the support frame 401, and with the use of bolts, the entire device structure can be fixed to the outside of the car generator.

[0026] In summary, as Figures 1 to 4As shown, the rear cover heat dissipation assembly of the car generator is used by first fitting the entire protective frame 4 onto the outside of the car generator and fixing the structure by using the support piles 402 around the support frame 401 and the bolts.

[0027] Then, the side of the main frame 101 with the docking hole 103 is inserted and docked with the buffer rod 403 connected to the buffer frame 404. At the same time, the assembly frame 2 with the silent fan 3 installed inside is inserted and docked with the docking groove 102 on the other side of the main frame 101 using the docking post 204 around one edge of the assembly tube frame 201. The connecting frame 1, the assembly frame 2 and the protective frame 4 are connected and fixed together with bolts.

[0028] During the operation of the car generator, the silent fan 3 inside the mounting frame 2 will dissipate the heat generated by its operation as quickly as possible. At the same time, with the combined use of the connecting frame 1 and the protective frame 4, the structural vibrations generated by the operation of the car generator and the silent fan 3 during operation are conducted, absorbed, and further attenuated, thereby reducing vibration and noise.
