Description

Technical Field

[0001] This utility model relates to the field of automotive generator technology, and in particular to a wind guide structure for an automotive generator. Background Technology

[0002] The automotive alternator is the core power source of the automotive power supply system. Its core function is to convert the mechanical energy output by the engine into electrical energy when the engine is running, so as to supply power to the vehicle's electrical equipment and charge the battery. It is a key component to ensure the normal operation of various automotive electrical systems.

[0003] In existing technologies, when a car generator is running, the rotation of the guide fan blades will create airflow. Debris such as lint and metal shavings in the engine compartment can easily enter the airflow system with the airflow. If the debris enters, it will entangle the guide fan blades, causing the blades to become unbalanced, make abnormal noises, or even break. It can also block the gaps between the heat-conducting fins and the air outlet, shortening the life of the equipment. Therefore, there is a need for an airflow structure for a car generator to meet people's needs. Utility Model Content

[0004] In view of the above problems, the technical problem to be solved by this utility model is to provide a wind guide structure for an automobile generator.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a wind guide structure for an automobile generator, including an automobile generator, wherein the automobile generator is provided with a plurality of temperature-conducting fins, and the output shaft of the automobile generator is provided with a flow guide fan blade; characterized in that: a flow guide cover is installed on one side of the automobile generator, the flow guide cover is provided with a flow guide structure, a fixing frame is detachably installed on one side of the flow guide cover, the fixing frame is provided with an interception structure, and two limiting sleeves are symmetrically installed on the flow guide cover, and a snap-fit ​​structure is provided in both limiting sleeves.

[0006] A further preferred embodiment of this utility model is: the airflow guiding structure includes several air inlets, which are opened on the airflow guiding shroud, and several air outlets are opened inside the airflow guiding shroud, with the air outlets corresponding to the positions of the temperature-conducting fins.

[0007] A further preferred embodiment of this utility model is: the interception structure includes an interception mesh plate, which is installed on a fixed frame and the position of the interception mesh plate corresponds to that of the air inlet.

[0008] A further preferred embodiment of this utility model is: a sealing ring is installed on one side of the flow guide, and a limiting groove is opened inside the fixing frame, with the sealing ring in contact with the inner wall of the limiting groove.

[0009] A further preferred embodiment of this utility model is as follows: the snap-fit ​​structure includes an L-shaped insert plate, which is installed on a fixed frame. One end of the L-shaped insert plate is inserted into the inside of the limiting sleeve. A slot is provided on the L-shaped insert plate. A fixed shaft is installed on the inner wall of the limiting sleeve. A hook is rotatably sleeved on the fixed shaft. The hook is snapped into the slot. One end of a torsion spring is installed on the fixed shaft. The other end of the torsion spring is installed on the inner wall of the hook.

[0010] A further preferred embodiment of this utility model is: a push rod is slidably installed inside the limiting sleeve, a spring is installed on one side of the push rod, and one end of the spring is installed on the inner wall of the limiting sleeve.

[0011] A further preferred embodiment of this utility model is: a guide rod is slidably installed inside the limiting sleeve, and one end of the guide rod is installed on the push rod.

[0012] Compared with the prior art, the present invention has the following advantages: 1. When the generator output shaft drives the guide fan blades to rotate, a stable negative pressure is formed inside the guide shroud. This guides external cold air to be drawn in through the air inlet and blown directly through the air outlet to the gap between the heat dissipation fins and the generator casing. This allows the cold air to fully contact the heat dissipation components and quickly remove the heat generated by the generator, effectively reducing the generator's operating temperature. At the same time, the interceptor plate filters out debris at the air inlet to prevent it from clogging the air outlet or wrapping around the guide fan blades, ensuring that the airflow channel remains unobstructed for a long time and further improving the cooling stability.

[0013] 2. The interceptor mesh is integrated into the fixed frame. The fixed frame is positioned by the L-shaped insert plate and the limiting sleeve of the flow guide. The hook is locked into the slot under the action of the torsion spring. When disassembling, simply press the hook to disengage from the slot. The compressed spring will push the push rod to push the L-shaped insert plate out of the limiting sleeve. The fixed frame and interceptor mesh can be quickly removed for cleaning or replacement, which improves the reusability of the structure. Attached Figure Description

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] This embodiment mainly describes the air guide structure of an automotive generator, as detailed below: like Figures 1-5 As shown, a wind-guiding structure for an automotive generator includes an automotive generator 100, which has several heat-conducting fins 101. The output shaft of the automotive generator 100 is provided with a guide fan blade 102. A guide shroud 200 is installed on one side of the automotive generator 100, and a guide structure is provided on the guide shroud 200. A fixing frame 300 is detachably installed on one side of the guide shroud 200, and an interception structure is provided on the fixing frame 300. Two limiting sleeves 400 are symmetrically installed on the guide shroud 200, and a snap-fit ​​structure is provided inside each of the two limiting sleeves 400.

[0020] When the car generator air guide structure is working, the heat generated during the operation of the car generator 100 is conducted to the heat-conducting fins 101. The output shaft synchronously drives the guide fan blades 102 to rotate. The guide structure guides the airflow to act precisely on the heat-conducting fins 101 to achieve efficient cooling. At the same time, the interception structure filters out impurities from the incoming airflow to prevent impurities from interfering with the operation of the equipment. When the interception structure needs to be cleaned or replaced, the fixing frame 300 can be quickly disassembled and installed through the snap-fit ​​structure.

[0021] Furthermore, the flow guiding structure includes several air inlets 201, which are opened on the flow guiding shroud 200. Several air outlets 202 are opened inside the flow guiding shroud 200, and the positions of the air outlets 202 correspond to those of the heat-conducting fins 101.

[0022] The airflow guiding structure, through the precise alignment design of the air inlet 201 and the air outlet 202, constructs a directional airflow channel. When the airflow guiding fan blades 102 rotate with the output shaft of the car generator 100, a negative pressure is formed inside the airflow guide shroud 200. External cold air is drawn into the airflow guide shroud 200 through the air inlet 201 and then dispersed and blown out through several air outlets 202. Since the air outlets 202 correspond to the heat-conducting fins 101, the blown-out cold air can flow directly through the gaps between the heat-conducting fins 101, fully contact the surface of the heat-conducting fins 101, and quickly remove the heat conducted by them. At the same time, part of the airflow covers the outer shell of the car generator 100, achieving cooling.

[0023] The interception structure includes an interception mesh plate 301, which is mounted on a fixed frame 300. The position of the interception mesh plate 301 corresponds to that of the air inlet 201. A sealing ring 302 is installed on one side of the flow guide shroud 200. A limiting groove 303 is opened inside the fixed frame 300, and the sealing ring 302 contacts the inner wall of the limiting groove 303.

[0024] The interception structure, through the alignment of the interception mesh plate 301 with the air inlet 201, intercepts debris at the source of airflow. Before entering the air inlet 201, external air must pass through the interception mesh plate 301 for filtration. Flocculent matter and other debris are intercepted on the outside of the mesh plate, effectively preventing debris from entering the inside of the air guide shroud 200 and entangled in the air guide fan blades 102 or blocking the air outlet 202, thus ensuring unobstructed airflow. At the same time, when the fixed frame 300 is installed, the sealing ring 302 on the air guide shroud 200 is embedded in the limiting groove 303 of the fixed frame 300, enhancing the connection and sealing between the fixed frame 300 and the air guide shroud 200.

[0025] like Figures 1-5 As shown, in order to facilitate the disassembly and assembly of the interception mesh panel 301 for cleaning or replacement, a snap-fit ​​structure is arranged. The snap-fit ​​structure includes an L-shaped insert plate 401, which is installed on the fixed frame 300. One end of the L-shaped insert plate 401 is inserted into the inside of the limiting sleeve 400. A slot 402 is provided on the L-shaped insert plate 401. A fixed shaft 403 is installed on the inner wall of the limiting sleeve 400. A hook 404 is rotatably sleeved on the fixed shaft 403. The hook 404 is snapped into the slot 402. One end of a torsion spring 405 is installed on the fixed shaft 403. The other end of the torsion spring 405 is installed on the inner wall of the hook 404.

[0026] The snap-fit ​​structure works in conjunction with the interception structure and the flow guiding structure to achieve quick assembly and disassembly of the interception mesh plate 301. During installation, press the snap hooks 404 on both sides to make them rotate around the fixed shaft 403 and compress the torsion spring 405. Insert the L-shaped insert plate 401 on the fixed frame 300 into the limiting sleeve 400. During the insertion process, the L-shaped insert plate 401 squeezes the push rod 406, causing the spring 407 to compress and store energy. At the same time, the limiting groove 303 of the fixed frame 300 fits into the sealing ring 302 to achieve a seal. When the L-shaped insert plate 401 is inserted into the correct position, release the snap hooks 404. The torsion spring 405 resets and drives the snap hooks 404 to flip and reset and snap into the slot 402, thus locking the fixed frame 300.

[0027] Furthermore, a push rod 406 is slidably installed inside the limiting sleeve 400, a spring 407 is installed on one side of the push rod 406, one end of the spring 407 is installed on the inner wall of the limiting sleeve 400, and a guide rod 408 is slidably installed inside the limiting sleeve 400, one end of the guide rod 408 is installed on the push rod 406.

[0028] When it is necessary to clean or replace the interceptor mesh plate 301, press the hook 404 to disengage it from the slot 402. The compressed spring 407 pushes the push rod 406 to move. Guided by the guide rod 408, the push rod 406 pushes the L-shaped insert plate 401 out of the limiting sleeve 400, so that the fixing frame 300 and the interceptor mesh plate 301 can be quickly removed, which greatly improves maintenance efficiency. The guide rod 408 not only provides precise guidance for the push rod 406, but also prevents the spring 407 from bending and deforming when compressed, ensuring the stable reuse of the snap-fit ​​structure.
