Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive generator technology, specifically relating to an installation structure and its automotive generator. Background Technology
[0002] An automotive alternator mainly consists of a rotor (which generates a rotating magnetic field), a stator (which generates three-phase alternating current), a rectifier (which converts alternating current to direct current), a voltage regulator (which stabilizes the output voltage, usually around 14V), as well as front and rear end covers, pulleys, and a cooling fan.
[0003] The input end (belt end) of the car alternator is connected to the crankshaft pulley of the engine. The belt drives the alternator pulley to rotate, transmitting mechanical energy. At the output end (terminal end), the alternator generates alternating current, which is converted into direct current by a rectifier and sent out to the battery and all electrical components of the vehicle through a thick cable.
[0004] Typically, a single serpentine belt connects not only the alternator but also drives the water pump, air conditioning compressor, power steering pump, and more. While rubber belts can absorb vibration and shock, protecting the alternator, their drawback lies in the fact that the engine crankshaft speed fluctuates wildly. Over time, this can cause the crankshaft belt at the alternator's output end to loosen. Currently, the industry generally relies on tension pulleys to maintain appropriate tension, but these pulleys are fixed in place and lack adjustment capabilities, failing to provide continuous tension based on the belt's deformation. Summary of the Invention
[0005] To address the technical problem in existing technologies where the crankshaft speed of an automobile engine fluctuates drastically, leading to loosening of the crankshaft belt at the output end of the automobile alternator after prolonged use, but the tensioner itself lacks adjustment and adaptation functions and cannot generate continuous tension based on the deformation of the belt, this invention provides an installation structure and its automobile alternator, including a housing, a hinge component, a first tensioning structure, and a connecting plate. The installation structure connects the motor body to the engine block, enabling continuous tension to be generated based on the deformation of the crankshaft belt at the output end of the motor body after it becomes loose.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] An installation structure includes a housing, a hinge component, a first tensioning structure, and a connecting plate;
[0008] The housing has an installation cavity, the first buffer mechanism is installed on the inner wall of the installation cavity, the first buffer mechanism is connected to the hinge component, and the end of the hinge component opposite to the first buffer mechanism is connected to the connecting plate.
[0009] Furthermore, the first tensioning structure includes a first spring rod, a mounting block, and a first spring. The first spring rod has a mounting block at each end, and the mounting block is fixed to the inner wall of the mounting cavity. There are two first springs, which abut against different sides of the mounting blocks. The ends of the two first springs away from the mounting blocks abut against a movable ring. The movable ring is sleeved on the first spring rod and can move along the first spring rod. Under the action of the first spring, the movable rings tend to move closer to each other.
[0010] Furthermore, the hinge component includes a connector and hinge rods. The connector is fixed to the connecting plate, and two hinge rods are hinged to the end of the connector away from the connecting plate. The two hinge rods are clamped to form an acute angle. The moving ring is fixed with a hinge ear. The ends of the hinge rods away from the connector are respectively hinged to the hinge ear, so that the angle formed between the two hinge rods can be changed after the moving ring moves.
[0011] Furthermore, guide heads are installed on both sides of the connecting plate, and the guide heads slide in conjunction with the grooves opened on the side wall of the mounting cavity.
[0012] Furthermore, a second tensioning structure is provided on both sides of the first tensioning structure. The second tensioning structure includes a telescopic cylinder and a second spring. The axis of the telescopic cylinder is perpendicular to the first spring rod. The telescopic cylinder is mounted on the fixed block. The end of the telescopic cylinder away from the fixed block is connected to one side of the connecting plate. The telescopic cylinder is fitted with the second spring. One end of the second spring abuts against one side of the connecting plate. The second spring applies a force to the connecting plate away from the telescopic cylinder.
[0013] Furthermore, this invention also claims protection for an automotive generator, comprising any of the aforementioned mounting structures, wherein a mounting post is fixedly mounted on a connecting plate of the mounting structure, the mounting post extending into the housing, a connecting seat is fixed to the motor body, the mounting post is fixed to the connecting seat, and under the action of a first tensioning structure and a second tensioning structure of the mounting structure, the pulley at the output end of the motor body can tension the belt.
[0014] Furthermore, a buffer rubber block is fixed on the side of the housing near the connecting seat, and there are four buffer rubber blocks, which are located near the corner of the housing.
[0015] Furthermore, the bottom of the housing is provided with several threaded holes, through which the housing is fixedly connected to the cylinder block of the automobile engine.
[0016] Compared with existing technologies, the beneficial effects of this solution are:
[0017] 1. This invention provides an installation structure and its automotive alternator, comprising a housing, a hinge component, a first tensioning structure, and a connecting plate. The housing has an installation cavity, a first buffer mechanism is installed on the inner wall of the installation cavity, and the first buffer mechanism is connected to the hinge component. The end of the hinge component facing away from the first buffer mechanism is connected to the connecting plate. This installation structure solves the problem of severe fluctuations in engine crankshaft speed, which can easily lead to loosening of the crankshaft belt at the output end of the automotive alternator after prolonged use. Compared to the tensioner pulley method of maintaining tension, this invention, through the setting of the first tensioning structure, can maintain continuous tension even after the belt deforms and loosens, thus possessing an adjustment and adaptation function.
[0018] 2. In some embodiments of the present invention, a second tensioning structure is provided on both sides of the first tensioning structure, thereby strengthening the tension of the connecting plate on the motor body. Specifically, the second tensioning structure includes a telescopic cylinder and a second spring. The axis of the telescopic cylinder is parallel to the groove on the inner wall of the mounting cavity. The telescopic cylinder is mounted on the fixed block, and the telescopic cylinder is fitted with the second spring. After installation, the second spring can push the connecting plate away from the first tensioning structure. Under the combined action of the first and second tensioning structures, the motor body can be kept in the engine. At the same time, the crankshaft speed of the engine fluctuates violently during operation. The mounting structure of the present invention solves the problem of synchronous vibration of the generator caused by the rigid connection between the generator and the engine in the prior art. It also avoids the problem of loosening of the crankshaft belt at the output end of the car generator after long-term use. Attached Figure Description

Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings.
[0025] An installation structure, such as Figure 3 and Figure 4 As shown, it includes a housing 11, a hinge component 12, a first tensioning structure 13, and a connecting plate 14;
[0026] The housing 11 has an installation cavity, the first buffer mechanism is installed on the inner wall of the installation cavity, the first buffer mechanism is connected to the hinge component 12, and the end of the hinge component 12 opposite to the first buffer mechanism is connected to the connecting plate 14.
[0027] According to a specific embodiment of the present invention, the housing 11 has a hexahedral structure and is disposed at the bottom of the motor body 2. It has a cavity structure and a hinge component 12, a first tensioning structure 13 and a connecting plate 14 are disposed inside the housing 11. The hinge component 12 is used to connect the first tensioning structure 13 and the connecting plate 14. The first tensioning structure 13 is used to generate tension on the motor body 2 and maintain tension. The connecting plate 14 is used to connect the motor body 2 and the mounting structure 1.
[0028] The installation structure 1 of the present invention solves the problem that the crankshaft belt at the output end of the car alternator is prone to loosening after long-term use due to the violent fluctuation of the engine crankshaft speed. Compared with the tensioner maintaining tension, the present invention can maintain continuous tension after the belt deforms and loosens through the setting of the first tensioning structure 13, thus having an adjustment and adaptation function.
[0029] Furthermore, the first tensioning structure 13 includes a first spring rod 131, a mounting block 132, and a first spring 133. The first spring rod 131 has a mounting block 132 at each end, and the mounting block 132 is fixed to the inner wall of the mounting cavity. There are two first springs 133, which abut against different sides of the mounting blocks 132. The ends of the two first springs 133 away from the mounting blocks 132 abut against a movable ring 134. The movable ring 134 is sleeved on the first spring rod 131 and can move along the first spring rod 131. Under the action of the first spring 133, the movable ring 134 tends to move closer to each other.
[0030] According to a specific embodiment of the present invention, a first tensioning structure 13 is provided. A first spring rod 131 is arranged parallel to the connecting plate 14. A mounting block 132 is fixed to both ends of the first spring rod 131. The first spring rod 131 passes through two moving rings 134. A first spring 133 is located between the mounting block 132 and the moving rings 134. Under the push of the respective first springs 133, the two moving rings 134 tend to move closer to each other.
[0031] Furthermore, the hinge component 12 includes a connector 121 and hinge rods 122. The connector 121 is fixed on the connecting plate 14. Two hinge rods 122 are hinged to the end of the connector 121 away from the connecting plate 14. The two hinge rods 122 are clamped to form an acute angle. The moving ring 134 is fixed with a hinge ear. The ends of the hinge rods 122 away from the connector 121 are respectively hinged to the hinge ear, so that the angle formed between the two hinge rods 122 can be changed after the moving ring 134 moves.
[0032] According to a specific embodiment of the present invention, this embodiment provides a specific structure of a hinge component 12. The hinge component 12 is used to connect a connecting plate 14 and a first tensioning structure 13. The hinge component 12 includes a connector 121 and a hinge rod 122. The connector 121 has a cylindrical end and a groove at the other end. The cylindrical end is fixed to the bottom of the connecting plate 14, and the grooved end is rotatably connected to one end of the hinge rod 122. The end of the hinge rod 122 away from the connecting plate 14 is rotatably connected to a hinge lug on a moving ring 134, so that when the first spring 133 pushes, the two moving rings 134 move closer to each other, causing the hinge rod 122 to rotate, thereby pushing the connecting plate 14 to move away from the first spring 133.
[0033] Furthermore, guide heads 141 are respectively installed on both sides of the connecting plate 14, and the guide heads 141 slide in conjunction with the sliding grooves opened on the sidewall of the mounting cavity. The connecting plate 14 can move under the restriction of the hinge component 12, making the movement of the connecting plate 14 more stable. In this embodiment, guide heads 141 are respectively installed on both sides of the connecting plate, and the sliding grooves are arranged parallel to the length direction of the connecting head 121.
[0034] Furthermore, a second tensioning structure 15 is provided on both sides of the first tensioning structure 13. The second tensioning structure 15 includes a telescopic cylinder 151 and a second spring 152. The axis of the telescopic cylinder 151 is perpendicular to the first spring rod 131. The telescopic cylinder 151 is mounted on the fixed block. One end of the telescopic cylinder 151 away from the fixed block is connected to the side of the connecting plate 14. The telescopic cylinder 151 is fitted with the second spring 152. One end of the second spring 152 abuts against the side of the connecting plate 14. The second spring 152 applies a force to the connecting plate 14 away from the telescopic cylinder 151.
[0035] According to a specific embodiment of the present invention, a second tensioning structure 15 is provided on both sides of the first tensioning structure 13, thereby strengthening the tension of the connecting plate 14 on the motor body 2. Specifically, the second tensioning structure 15 includes a telescopic cylinder 151 and a second spring 152. The axial direction of the telescopic cylinder 151 is parallel to the sliding groove on the inner wall of the mounting cavity. The telescopic cylinder 151 is mounted on the fixed block, and the telescopic cylinder 151 is fitted with the second spring 152. After installation, the second spring 152 can push the connecting plate 14 away from the first tensioning structure 13. Under the combined action of the first tensioning structure 13 and the second tensioning structure 15, the motor body 2 can be kept in the engine. At the same time, the crankshaft speed of the engine fluctuates violently when it is running. The mounting structure 1 of the present invention solves the problem of synchronous vibration of the generator caused by the rigid connection between the generator and the engine in the prior art, and can also avoid the problem of loosening of the crankshaft belt at the output end of the car generator after long-term use.
[0036] Furthermore, this invention also claims protection for an automotive generator, such as...

[0037] According to a specific embodiment of the present invention, the connecting seat 3 is disposed at the bottom of the motor body 2 and is disposed opposite to the housing 11. The connecting seat 3 is connected to the connecting plate 14 through a fixed mounting post 142, so that the first tensioning structure 13 and the second tensioning structure 15 can transmit force to the motor body 2.
[0038] Furthermore, four buffer rubber blocks 16 are fixed to the side of the housing 11 near the connecting seat 3, and are located near the corner of the housing 11. The connecting seat 3 can contact the buffer rubber blocks 16 on the housing 11 by means of the connection seat 3.
[0039] Furthermore, the bottom of the housing 11 is provided with several threaded holes, and the housing 11 is fixedly connected to the automobile engine cylinder block through the threaded holes. Specifically, four countersunk threaded holes are provided at the bottom of the housing 11, and a screw passes through the automobile engine cylinder block and connects to the threaded holes of the housing 11.
