Description

Technical Field

[0001] This invention belongs to the field of vehicle parts technology, and in particular relates to a radiator device for an all-terrain vehicle and its usage method. Background Technology

[0002] All-terrain vehicles (ATVs) are vehicles that can travel on any terrain. A radiator is an important component of an ATV, used for cooling the engine system. For example, a car radiator disclosed in patent application number CN202410026377.8 includes a radiator pipe inside the housing; an inlet fixed to one end of the radiator pipe; and an outlet fixed to the other end of the radiator pipe. By setting a deflector plate, the vehicle generates wind during travel, which drives the blades to rotate. The blades drive the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the rotating rod to rotate, and the rotating rod drives the fan to rotate. The fan generates wind that blows onto the radiator pipe and fins. Simultaneously, as the rotating rod rotates, it drives a rotating block to rotate. The rotating block slides within a limiting groove and is pressed by the rotating block. During rotation, the rotating block drives the limiting block to swing back and forth, which in turn drives the horizontal plate to swing back and forth. The horizontal plate drives the deflector plate to swing back and forth, and the deflector plate repeatedly contacts two adjacent fins.

[0003] In the use of existing vehicle radiators, the shroud design at the fan increases resistance during high-speed driving, thereby reducing the cooling airflow. At the same time, the gap between the radiator and the fan allows airflow to easily bypass the gaps in the radiator's copper pipes and enter the fan when the vehicle is at low speeds and the fan is forced to draw air, which greatly reduces the cooling efficiency. Furthermore, in order to keep the environment of the radiator and engine system clean, filter plates are usually added to the front or rear of the radiator. However, under the influence of the operating environment of all-terrain vehicles, the design of the filter plate structure requires frequent maintenance of the radiator to maintain airflow, which greatly reduces the operational stability of the radiator. Therefore, it is necessary to make improvements. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a radiator device for all-terrain vehicles and its usage method, thereby improving the heat dissipation efficiency and operational stability of the radiator device for all-terrain vehicles.

[0005] In view of this, the present invention provides a radiator device for an all-terrain vehicle, comprising:

[0006] The radiator body is provided with an inlet pipe, an outlet pipe, a front air inlet surface, and a rear air outlet surface.

[0007] Also includes:

[0008] A radiator fan is arranged side by side with the radiator body. The radiator fan includes a motor, multiple fan blades that are driven to rotate by the motor, and a fan retaining ring located on the outer periphery of the multiple fan blades.

[0009] Mounting bracket, which is set on the rear air outlet surface of the radiator body to support the radiator fan and motor;

[0010] A baffle plate, wherein the baffle plate is integrally formed with the mounting bracket;

[0011] The baffle plate covers the gap between the radiator and the fan baffle ring when viewed from a direction orthogonal to the direction in which the radiator body and the radiator fan are arranged.

[0012] In this technical solution, during the use of the all-terrain vehicle, air enters from the front air intake of the radiator body, absorbs heat as it passes through the radiator body, and is drawn away by the radiator fan after passing through the rear air outlet. The radiator fan and motor are mounted on the rear side of the radiator body by a mounting bracket, which can effectively reduce resistance at high speeds and increase the cooling airflow. At the same time, the baffle avoids the air short-circuit flow problem caused by the lack of a protective cover. At low speeds, the baffle can effectively prevent air from directly entering the fan from around the radiator. The air must pass through the radiator, thus effectively ensuring the cooling efficiency.

[0013] In the above technical solution, a pair of baffles are further provided in a direction orthogonal to the direction in which the radiator body and the radiator fan are arranged.

[0014] In the above technical solution, the baffle plate is further distributed below the gap between the heat sink and the fan baffle ring.

[0015] Furthermore, the above technical solution also includes:

[0016] A mudguard is mounted on a mounting bracket and located behind the radiator body and radiator fan. The mudguard only covers the area from the bottom of the radiator body to the center of the radiator fan.

[0017] Furthermore, the above technical solution also includes:

[0018] A pre-filter structure, the pre-filter structure including a filter plate disposed in front of the air inlet on the front side of the heat dissipation body.

[0019] In the above technical solution, the pre-filter structure further includes:

[0020] A cleaning roller is arranged on the front side of the filter plate. The cleaning roller can be moved back and forth along the left and right direction of the filter plate by the drive unit to clean the filter surface of the filter plate.

[0021] The cleaning roller moves from the left side of the filter plate to the right side, attaches to the filter surface of the filter plate and cleans the filter surface, and moves from the right side of the filter plate to the left side, separates from the filter plate and returns to its initial position.

[0022] In the above technical solution, the driving unit further includes:

[0023] The fixing frame has two symmetrically distributed on the upper and lower sides of the filter plate, and the front side of the fixing frame has a slot for the shaft end of the cleaning roller to pass through.

[0024] Waist-shaped guide groove, the waist-shaped guide groove is disposed on the surface of the fixing frame away from the filter plate;

[0025] A transmission arm, which is provided with a pulley set, a gear set, a drive gear in the drive gear set, and a drive unit for rotating the drive pulley in the pulley set;

[0026] The inner surface of the waist-shaped guide groove has toothed grooves that cooperate with the gear set and the toothed grooves extend along the contour direction of the guide groove. The shaft end of the cleaning roller is connected to the driven pulley in the pulley set. The transmission arm can reciprocate along the left and right direction of the filter plate and drive the cleaning roller to reciprocate left and right under the cooperation of the drive unit, the gear set and the waist-shaped guide groove. At the same time, the transmission arm can reciprocate along the front and back direction of the filter plate and drive the cleaning roller to fit or separate from the filter surface of the filter plate.

[0027] Furthermore, in the above technical solution, the present invention also discloses a method for using a radiator device suitable for all-terrain vehicles, comprising the following steps:

[0028] S1 Low-speed cooling: When the all-terrain vehicle is at low speed or idling speed, the radiator fan runs to force airflow, and at the same time the baffle blocks the gap between the radiator and the radiator fan and forces the fan to flow through the radiator.

[0029] S2 High-speed cooling: When the all-terrain vehicle is at high speed, the radiator fan is fixed to the rear air outlet surface of the radiator body by the mounting bracket, and natural air is efficiently cooled by passing through the radiator.

[0030] The S3 pre-filter filters the airflow into the radiator, radiator fan, and power system using filter plates.

[0031] S4 Filter plate cleaning: After determining the clogging status of the filter plate, when the filter plate is clogged, the cleaning roller moves back and forth to clean the filter surface of the filter plate.

[0032] In this technical solution, the radiator of the all-terrain vehicle can maintain high heat dissipation efficiency at both high and low speeds. At the same time, the pre-filter can effectively keep the radiator body and engine system clean. The filter plate can automatically clean itself according to the blockage during use, thereby maintaining the working stability of the radiator.

[0033] The beneficial effects of this invention are:

[0034] 1. The design of the baffle plate on the mounting bracket can effectively improve heat dissipation performance and ensure heat dissipation efficiency;

[0035] 2. The integrated design reduces the number of parts, thus lowering assembly costs;

[0036] 3. The pre-filter structure keeps the environment around the radiator and engine system clean, further ensuring the heat dissipation effect. The filter plate can also be automatically cleaned, ensuring the stability of the heat dissipation operation. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0047] Example 1:

[0048] This application provides a radiator device for an all-terrain vehicle, including: a radiator body 1, on which an inlet pipe 100, an outlet pipe 101, a front air inlet surface 102, and a rear air outlet surface 103 are provided.

[0049] It also includes: a radiator fan 2, which is arranged side by side with the radiator body 1. The radiator fan 2 includes a motor 20, multiple fan blades 21 driven to rotate by the motor 20, and fan baffles 22 located around the multiple fan blades 21; a mounting bracket 3, which is set on the rear air outlet surface 103 of the radiator body 1 to support the radiator fan 2 and the motor 20; and a baffle plate 4, which is integrally formed with the mounting bracket 3.

[0050] The baffle 4 covers the gap 5 between the radiator and the fan baffle 22 when viewed from a direction orthogonal to the direction in which the radiator body 1 and the radiator fan 2 are arranged.

[0051] A pair of baffles 4 are provided in a direction orthogonal to the direction in which the heat sink body 1 and the heat sink fan 2 are arranged.

[0052] The baffle 4 is located below the gap 5 between the heat sink and the fan baffle 22.

[0053] Also includes:

[0054] The mudguard is mounted on the mounting bracket 3 and is located behind the radiator body 1 and the radiator fan 2. The mudguard only covers the area from the bottom of the radiator body to the center of the radiator fan 2.

[0055] In this embodiment, during the use of the all-terrain vehicle, air enters from the front air intake surface 102 of the radiator body 1, absorbs heat as it passes through the radiator body 1, and is drawn away by the radiator fan 2 through the rear air outlet surface 103. The radiator fan 2 and the motor 20 are installed on the rear side of the radiator body 1 by the mounting bracket 3, which can effectively reduce the resistance at high speeds and increase the cooling air volume. At the same time, the baffle 4 avoids the air short-circuit flow problem caused by the lack of a protective cover design, so that at low speeds, the baffle 4 can effectively prevent air from directly entering the fan from around the radiator. The air must pass through the radiator, thus effectively ensuring the cooling efficiency. The mudguard can further prevent mud from entering the radiator fan 2 and affecting the operation of the radiator fan 2.

[0056] Furthermore, the all-terrain vehicle includes a frame for mounting the engine system, a wheel supported by a steerable frame, a fairing mounted on the frame, and other conventional all-terrain vehicle structures. Taking the water-cooled engine system as an example, the radiator cools the engine system's coolant through cooling air. Most of the radiator is located in the frame and at the front of the engine system. The radiator body 1 and the cooling fan are arranged in the direction of the cooling air intake at the front of the frame. The radiator body 1 has a height in the vertical direction, a width in the left-right direction of the all-terrain vehicle, and a thickness in the front-rear direction of the all-terrain vehicle, thus forming a roughly rectangular plate shape.

[0057] The radiator body 1 also includes a heat dissipation core and a left and right housing distributed on both sides of the heat dissipation core. The heat dissipation core is conventionally configured such that the cooling pipes and cooling fins are stacked in the height direction of the heat dissipation core. The cooling pipes extend in the width direction of the heat dissipation core and coolant flows through the cooling pipes. Cooling air passes from the front air intake surface 102 of the heat dissipation core through the cooling fins between adjacent cooling pipes in the height direction of the heat dissipation core, thereby cooling the coolant flowing through the cooling pipes. The thickness direction of the heat dissipation core is the direction in which the cooling air passes through the heat dissipation core. The height direction of the heat dissipation core is a direction orthogonal to the width direction of the heat dissipation core in a roughly vertical direction. The width direction of the radiator is a direction orthogonal to the height and thickness directions of the heat dissipation core. The right housing is the part where the engine system coolant flows in, and the left housing is the part where the engine cooling system coolant flows out. The left and right housings can be metal housings or synthetic resin housings.

[0058] The mounting bracket 3 can be made of synthetic resin. The fan blade 21 is mounted on the center of the radiator body 1 through the mounting bracket 3, and is close to the gap 5 between the fan blade 21 and the rear air outlet surface 103 of the radiator body 1. The front surface of the fan baffle 22 is located on the center of the radiator body 1, and is close to the gap 5 between the fan blade 21 and the rear air outlet surface 103 of the radiator body 1. The gap 5 is about 1mm to 8mm in size. The gap 5 is set to prevent the radiator fan 2 from contacting the rear air outlet surface 103 of the radiator body 1 due to vibration during driving.

[0059] Specifically, the mounting bracket 3 has a motor 20 side mounting part for mounting the motor 20, a radiator side mounting part for mounting the radiator body 1, and an arm mounting part connecting the two. The motor 20 can be mounted on the motor 20 side mounting part by conventional bolts. The arm mounting part protrudes from the upper and lower parts of the motor 20 side mounting part, and a radiator side mounting part is provided at the end of the arm mounting part. The radiator body 1 has a mounting plate that cooperates with the radiator side mounting part. The radiator side mounting part is installed and fixed by cooperating with the mounting plate by conventional bolts.

[0060] The baffle 4 has a portion installed near the mounting portion on the side of the radiator and a base extending from that portion. The baffle 4 is flat and is arranged parallel to the radiator body 1 and parallel to the axis of the radiator fan 2.

[0061] Example 2:

[0062] This embodiment provides a radiator device for an all-terrain vehicle. In addition to the technical solutions of the above embodiments, it also has the following technical features, including: a front filter structure 6, which includes a filter plate disposed in front of the air intake surface 102 on the front side of the radiator body.

[0063] The pre-filter structure 6 also includes a cleaning roller 7, which is arranged on the front side of the filter plate. The cleaning roller 7 can be driven by the drive unit 8 to move back and forth along the left and right direction of the filter plate and clean the filter surface of the filter plate.

[0064] When the cleaning roller 7 moves from the left side to the right side of the filter plate, it adheres to the filter surface of the filter plate and cleans the filter surface. When it moves from the right side to the left side of the filter plate, it separates from the filter plate and returns to its initial position.

[0065] The drive unit 8 also includes: a fixed frame 80, which has two symmetrically distributed on the upper and lower sides of the filter plate, and the front side of the fixed frame 80 has a slot 81 through which the shaft end of the cleaning roller 7 passes; a waist-shaped guide groove 82, which is provided on the surface of the fixed frame 80 away from the filter plate; and a transmission arm 83, which is provided with a pulley set 84, a gear set 85 and a drive unit 86 for rotating the drive pulley in the pulley set 84.

[0066] The inner surface of the waist-shaped guide groove 82 has a toothed groove 87 that mates with the gear set 85 and the toothed groove 87 extends along the contour direction of the guide groove. The shaft end of the cleaning roller 7 is connected to the driven pulley in the pulley set 84. The transmission arm 83 can reciprocate along the left and right direction of the filter plate under the cooperation of the drive unit 86, the gear set 85 and the waist-shaped guide groove 82, and drive the cleaning roller 7 to reciprocate left and right. At the same time, the transmission arm 83 can reciprocate along the front and back direction of the filter plate and drive the cleaning roller 7 to fit or separate from the filter plate filter surface.

[0067] Furthermore, the surface of the fixed frame 80 away from the filter plate has a pair of guide rails. The preferred pair of guide rails are symmetrically distributed with respect to the slot 81. The guide rails extend along the left and right direction of the filter plate. A slider is installed on the guide rail, and the slider slides with the guide rail. The top of the slider (the end of the slider away from the guide rail) has a movable slot. A part of the transmission arm 83 is movably embedded in the movable slot. The pulley assembly 84 includes a driving pulley and a driven pulley, and a transmission belt connecting the two. The driven pulley is rotatably mounted on the transmission arm 83 and is rotatably connected to the end of the cleaning shaft. A frame is installed at the end of the transmission arm 83 away from the slot 81. The drive unit 86 is mounted on the transmission arm 83 through the frame. The drive unit 86 can be a conventional rotary electric motor. The driving pulley is rotatably connected to the drive end of the drive unit 86. The gear set 85 includes a driving gear and first and second driven gears. The driving gear is rotatably mounted on the transmission arm 83 and is coaxially distributed with the drive unit 86 and the driving pulley. The driving gear is rotatably connected to the driving pulley through a conventional shaft. The driven gear is rotatably mounted on the transmission arm 83 and located on one side of the transmission arm 83 (the side away from the waist-shaped guide groove 82). The first driven gear meshes with the driving gear. The second driven gear is located on the other side of the transmission arm 83 (the side closer to the waist-shaped guide groove 82) and is connected to the first driven gear via a conventional shaft. The second driven gear meshes with the toothed groove 87 on the inner surface of the waist-shaped guide groove 82. The waist-shaped guide groove 82 also has a positioning protrusion, and the vertical cross-section of the positioning protrusion in the front-rear direction is T-shaped. The positioning protrusion consists of a web plate connected to the bottom surface of the waist-shaped guide groove 82 and a wing plate fixed to the top of the web plate. The horizontal cross-sections of the web plate and the wing plate in the left and right directions are roughly waist-shaped and concentrically distributed with the outline of the waist-shaped guide groove 82. The bottom surface of the wing plate, the side surface of the web plate, the bottom surface and the inner surface of the waist-shaped guide groove 82 together form a limiting groove. A limiting block is movably installed in the limiting groove. The limiting block is roughly cylindrical and is rotatably connected to the second driven gear through a conventional shaft.

[0068] In this embodiment, when the cleaning roller 7 cleans the filter surface of the filter plate, the drive unit 86 drives the drive pulley and drive gear to rotate. The drive pulley drives the driven pulley to rotate through the transmission belt, ultimately causing the cleaning roller 7 to rotate. The drive gear drives the first driven gear to rotate, and the second driven gear rotates along with the first driven gear. The second driven gear meshes with the tooth groove 87 on the inner surface of the waist-shaped guide groove 82, so that the second driven gear moves along the contour of the waist-shaped guide groove 82 during rotation, driving the transmission arm 83 to move along the left and right direction of the filter plate. When the cleaning roller 7 moves from left to right to clean the filter surface of the filter plate, the second driven gear moves along the inner surface of the waist-shaped guide groove 82 away from the cleaning roller 7, thereby making the cleaning roller 7 and the filter plate... When the cleaning roller 7 moves from right to left into the reset stroke, the second driven gear moves to the end of the waist-shaped guide groove 82 and then switches to the inner surface of the waist-shaped guide groove 82 near the cleaning roller 7. At this time, the transmission arm 83 is synchronously driven to move from back to front, ultimately causing the cleaning roller 7 to separate from the filter surface of the filter plate. This process is repeated to clean the filter surface of the filter plate. Through the above cleaning and filtration, the cleaning roller 7 can effectively remove impurities attached to the surface of the filter plate, while achieving unidirectional cleaning. This prevents the cleaning roller 7 from causing secondary pollution to the filter surface of the filter plate during the reciprocating cleaning process, thus improving the cleaning effect of the cleaning roller 7. Compared with the prior art, the present invention can effectively prevent the filter plate from clogging and improve the working stability of the radiator device.

[0069] Example 3:

[0070] This embodiment provides a method for using a radiator device for an all-terrain vehicle. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including the following steps:

[0071] S1 Low-speed cooling: When the all-terrain vehicle is at low speed or idling speed, the radiator fan 2 runs to force airflow, and at the same time the baffle 4 blocks the gap 5 between the radiator and the radiator fan 2 and forces the fan to flow through the radiator.

[0072] S2 High-speed cooling: When the all-terrain vehicle is in high-speed mode, the radiator fan 2 is fixed to the rear air outlet surface 103 of the radiator body 1 by the mounting bracket 3, and the natural wind efficiently passes through the radiator for cooling.

[0073] S3 pre-filter: The filter plate in the pre-filter mechanism filters the natural air flowing into the radiator, radiator fan 2 and power supply system.

[0074] S4 Cleaning the clogged filter plate: After determining the clogging status of the filter plate, when the filter plate is clogged, the cleaning roller 7 moves back and forth to clean the filter surface of the filter plate.

[0075] Furthermore, it also includes a humidity sensor arranged on the air inlet side of the filter plate, a current sensor at the motor 20 of the fan, and a wind speed sensor arranged on the air inlet or outlet side of the filter plate. It also includes a low-power MCU (such as STM32) for processing multi-sensor data and running judgment algorithms. Preferably, differential pressure sensors can also be arranged on both sides of the filter plate. Optionally, the current judgment threshold formula is: final threshold = (XY) × K, where X is the first reference setting value (such as 20mA, preset according to the wind speed level), Y is the humidity compensation value (such as Y=3mA when the humidity is high), and K is the wind speed compensation coefficient (when there is natural wind interference, K is equal to the measured wind speed / rated wind speed).

[0076] In this embodiment, by using the radiator device through the above method, a high heat dissipation efficiency can be maintained in both high-speed and low-speed states of the all-terrain vehicle. At the same time, the pre-filter can effectively keep the radiator body 1 and the engine system clean. During use, even in the complex environment where the all-terrain vehicle is located, the pre-filter structure 6 can automatically clean itself according to the blockage, thereby maintaining the working stability of the radiator device.
