Description

Technical Field

[0001] The invention belongs to the technical field of vehicle accessories, and in particular relates to a radiator device of an all-terrain vehicle and a use method thereof. Background Art

[0002] An all-terrain vehicle refers to a vehicle that can travel on any terrain, and a radiator device is an important component of an all-terrain vehicle, which is used for cooling and dissipating heat of an engine system. For example, a car radiator disclosed in the patent with application number CN202410026377.8 includes a heat dissipation pipe arranged inside a box body; a liquid inlet connected and fixedly connected to one end of the heat dissipation pipe; and a liquid outlet connected and fixedly connected to the other end of the heat dissipation pipe. By setting a toggle plate, the car generates wind force during the movement, and the wind force 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, the rotating rod drives the fan to rotate, and the fan generates wind force to blow onto the heat dissipation pipe and the fins. At the same time, during the rotation of the rotating rod, the rotating rod drives the rotating block to rotate, the rotating block slides in the limiting groove, and is pressed by the rotating block. During the rotation, the rotating block drives the limiting block to swing back and forth, the limiting block drives the cross plate to swing back and forth, the cross plate drives the toggle plate to swing back and forth, and the toggle plate touches two adjacent fins back and forth.

[0003] During use of this existing vehicle radiator, the guard design at the fan will increase resistance during high-speed driving, thereby reducing the heat dissipation air volume. At the same time, during the operation of the fan, when the fan is forced to draw air at a low speed of the vehicle, the airflow can easily bypass the gap between the radiator copper tubes and enter the fan directly, thereby greatly reducing the heat dissipation efficiency. In the prior art, in order to keep the environment in which the radiator and the engine system are located clean, a filter plate structure is usually added to the front or rear side of the radiator. However, under the influence of the use environment of the all-terrain vehicle, the design of the filter plate structure requires frequent maintenance of the radiator device to keep the airflow unobstructed, which greatly reduces the use stability of the radiator device, and therefore it is necessary to make improvements. Summary of the invention

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0054] Embodiment 1:

[0055] An embodiment of the present application provides a radiator device for an all-terrain vehicle, including: a radiator main 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;

[0056] It further includes: a radiator fan 2, which is arranged side by side with the radiator main body 1. The radiator fan 2 includes a motor 20, a plurality of fan blades 21 driven by the motor 20 to rotate, and a fan retaining ring 22 located on the outer periphery of the plurality of fan blades 21; a mounting bracket 3, which is arranged on the rear air outlet surface 103 of the radiator main body 1 for supporting the radiator fan 2 and the motor 20; a baffle 4, which is integrally formed with the mounting bracket 3;

[0057] Wherein, when observed from a direction orthogonal to the direction in which the radiator main body 1 and the radiator fan 2 are arranged, the baffle 4 covers the gap 5 between the radiator and the fan retaining ring 22.

[0058] A pair of baffle plates 4 are arranged in a direction orthogonal to the direction in which the radiator main body 1 and the radiator fan 2 are arranged.

[0059] The baffle 4 is distributed below the gap 5 between the radiator and the fan retaining ring 22.

[0060] It further includes:

[0061] A mudguard, which is arranged on the mounting bracket 3 and is located behind the radiator main body 1 and the radiator fan 2. The mudguard only covers the range from below the radiator main body to the center of the radiator fan 2.

[0062] In this embodiment, during the use of the all-terrain vehicle, air enters from the front air inlet surface 102 of the radiator main body 1, absorbs heat during the process of passing through the radiator main body 1, and is drawn away by the radiator fan 2 through the rear air outlet surface 103. By installing the radiator fan 2 and the motor 20 on the rear side of the radiator main body 1 through the mounting bracket 3, the resistance during high-speed driving can be effectively reduced, the heat dissipation air volume can be increased, and at the same time, the baffle 4 is used to avoid the air short-circuit flow problem caused by the non-shield design, so that the baffle 4 can effectively prevent air from directly entering the fan from around the radiator in the low-speed state, and the air must pass through the radiator, thereby effectively ensuring the heat dissipation efficiency. The mudguard can further prevent sludge from entering the radiator fan 2 and affecting the operation of the radiator fan 2.

[0063] Moreover, an all-terrain vehicle includes a frame for mounting an engine system, a wheel steerably supported by the frame, a fairing mounted on the frame, and other conventional all-terrain vehicle structures. Taking a water-cooled engine system as an example, a radiator device cools the cooling water of the engine system through cooling air. Most of the radiator device is disposed in the frame and located on the front side of the engine system. The radiator main body 1 and the radiator fan are arranged and distributed in the direction of the cooling air entering the front side of the frame. The radiator main body 1 has a height in the up-and-down 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 generally forming a rectangular plate shape.

[0064] The radiator main body 1 further includes a radiator core, a left box body and a right box body distributed on both sides of the radiator core. The radiator core is conventionally arranged such that cooling tubes and cooling fins are stacked in the height direction of the radiator core. The cooling tubes extend in the width direction of the radiator core and cooling water flows through the cooling tubes. And the cooling air passes through the cooling fins between the cooling tubes adjacent in the height direction of the radiator core from the front air inlet surface 102 of the radiator core, thereby cooling the cooling water flowing through the cooling tubes. The thickness direction of the radiator core is the direction through which the cooling air of the radiator core passes. The height direction of the radiator core is a direction orthogonal to the width direction of the radiator core in the generally up-and-down direction. The width direction of the radiator is a direction orthogonal to the height direction and the thickness direction of the radiator core. The right box body is the part where the cooling water of the engine system flows in. The left box body is the part where the cooling water of the engine cooling system flows out. The left box body and the right box body can be metal box bodies or synthetic resin box bodies.

[0065] The mounting bracket 3 can be made of synthetic resin. The fan blade 21 is disposed at the center of the radiator main body 1 through the mounting bracket 3 and is close to the rear air outlet surface 103 of the radiator main body 1 with a gap 5. And the front surface of the fan retaining ring 22 is disposed at the center of the radiator main body 1 and is close to the rear air outlet surface 103 of the radiator main body 1 with a gap 5. Additionally, the size of the gap 5 is about 1 mm to 8 mm. The gap 5 is provided to prevent the contact between the radiator fan 2 and the rear air outlet surface 103 of the radiator main body 1 due to vibration during driving.

[0066] Specifically, the mounting bracket 3 has a motor 20 side mounting portion mounted on the motor 20, a radiator side mounting portion mounted on the radiator main body 1, and an arm mounting portion connecting the two. The motor 20 can be mounted on the motor 20 side mounting portion through conventional bolts. The arm mounting portion protrudes up and down from the motor 20 side mounting portion, and the radiator side mounting portion is provided at the end of the arm mounting portion. The radiator main body 1 has a mounting plate cooperating with the radiator side mounting portion. The radiator side mounting portion is cooperatively mounted and fixed to the mounting plate through conventional bolts.

[0067] The baffle plate 4 has a portion installed near the radiator side mounting portion and a base extending from the portion. The baffle plate 4 is in a flat plate shape and is arranged parallel to the radiator body 1 and the axis of the radiator fan 2 .

[0068] Embodiment 2:

[0069] The present embodiment provides a radiator device for an all-terrain vehicle. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features, including: a pre-filter structure 6, the pre-filter structure 6 includes a filter plate arranged in front of the air inlet surface 102 on the front side of the heat dissipation body.

[0070] The pre-filter structure 6 further includes: a cleaning roller 7, which is arranged on the front side of the filter surface of the filter plate. The cleaning roller 7 can be driven by the driving unit 8 to reciprocate along the left and right directions of the filter plate and clean the filter surface of the filter plate;

[0071] When the cleaning roller 7 moves from the left side to the right side of the filter plate, it contacts the filter surface of the filter plate and cleans the filter surface of the filter plate. When it moves from the right side to the left side of the filter plate, it separates from the filter plate and returns to the initial position.

[0072] The driving part 8 also includes: a fixed frame 80, the fixed frame 80 has two and 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 for the shaft end of the cleaning roller 7 to pass through; a waist-shaped guide groove 82, the waist-shaped guide groove 82 is arranged on the surface of the fixed frame 80 away from the filter plate; a transmission arm 83, the transmission arm 83 is provided with a pulley group 84, a gear group 85 and a driving gear in the driving gear group 85 and a driving unit 86 for rotating the driving pulley in the pulley group 84;

[0073] Among them, the inner surface of the waist-shaped guide groove 82 has a tooth groove 87 that cooperates with the gear set 85, and the tooth groove 87 extends and is distributed along the contour direction of the guide groove. The axial 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 directions of the filter plate under the cooperation of the driving 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 directions of the filter plate and drive the cleaning roller 7 to fit or separate from the filtering surface of the filter plate.

[0074] Moreover, the surface of the fixing frame 80 away from the filter plate has a pair of guide rails. Preferably, the pair of guide rails are symmetrically distributed with respect to the slot 81. The guide rails extend along the left-right direction of the filter plate. Sliders are installed on the guide rails, and the sliders are slidably engaged with the guide rails. An activity slot is provided at the top end of the slider (the end of the slider away from the guide rail). A part of the transmission arm 83 is movably embedded in the activity slot. The pulley set 84 includes a driving pulley, a driven pulley, and a transmission belt that drives the two. The driven pulley is rotatably installed on the transmission arm 83 and is in transmission connection with the shaft end of the cleaning member. A frame body is installed at the end of the transmission arm 83 away from the slot 81. The driving unit 86 is installed on the transmission arm 83 through the frame body. The driving unit 86 can be a conventional rotating motor. The driving pulley is in transmission connection with the driving end of the driving unit 86. The gear set 85 includes a driving gear, a first driven gear, and a second driven gear. The driving gear is rotatably installed on the transmission arm 83 and is coaxially distributed with the driving unit 86 and the driving pulley. The driving gear is rotatably connected to the driving pulley through a conventional shaft. The first driven gear is rotatably installed on the transmission arm 83 and is located on one side of the transmission arm 83 (the side away from the waist-shaped guiding slot 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 close to the waist-shaped guiding slot 82) and is in transmission connection with the first driven gear through a conventional shaft. The second driven gear meshes with the tooth slot 87 on the inner surface of the waist-shaped guiding slot 82. The waist-shaped guiding slot 82 also has a positioning projection. The vertical cross-section of the positioning projection in the front-back direction is T-shaped, that is, the positioning projection is composed of a web connected to the bottom surface of the waist-shaped guiding slot 82 and a wing plate fixed on the top of the web. The horizontal cross-sections of the web and the wing plate in the left-right direction are both approximately waist-shaped and are concentric with the contour of the waist-shaped guiding slot 82. The bottom surface of the wing plate of the positioning projection, the side surface of the web, the bottom surface and the inner surface of the waist-shaped guiding slot 82 together form a limiting slot. A limiting block is movably installed in the limiting slot. The limiting block is approximately cylindrical. The limiting block is rotatably connected to the second driven gear through a conventional shaft.

[0075] In this embodiment, when the cleaning roller 7 cleans the filtering surface of the filter plate, the driving unit 86 drives the driving pulley and the driving gear to rotate. The driving pulley drives the driven pulley to rotate through the transmission belt, and finally the cleaning roller 7 rotates. The driving gear drives the first driven gear to rotate, and the second driven gear rotates as the first driven gear rotates. The second driven gear meshes with the tooth groove 87 on the inner surface of the kidney-shaped guide groove 82, so that the second driven gear moves along the contour of the kidney-shaped guide groove 82 during rotation, driving the transmission arm 83 to move in the left-right direction of the filter plate. When the cleaning roller 7 moves from left to right to clean the filtering surface of the filter plate, the second driven gear moves along the inner surface of the kidney-shaped guide groove 82 on the side away from the cleaning roller 7, so that the cleaning roller 7 fits the filtering surface of the filter plate. When the cleaning roller 7 moves from right to left and enters the reset stroke, the second driven gear moves to the end of the kidney-shaped guide groove 82 and is transferred to the inner surface of the kidney-shaped guide groove 82 on the side close to the cleaning roller 7 through the end. At this time, the transmission arm 83 is driven synchronously and moves from back to front, and finally the cleaning roller 7 is separated from the filtering surface of the filter plate. In this way, the filtering surface of the filter plate is cleaned reciprocally. Through the above cleaning and filtering, the cleaning roller 7 can effectively handle the impurities attached to the surface of the filter plate, and at the same time realize one-way cleaning, preventing the cleaning roller 7 from causing secondary pollution to the filtering surface of the filter plate during the reciprocating cleaning process, improving the cleaning effect of the cleaning roller 7. Compared with the prior art, the present invention can effectively prevent the filter plate from being blocked and improve the working stability of the radiator device.

[0076] Embodiment 3:

[0077] This embodiment provides a method for using a radiator device of an all-terrain vehicle. In addition to including the technical solutions of the above embodiments, it also has the following technical features, including the following steps:

[0078] S1 Cooling at low speed. When the all-terrain vehicle is in a low-speed state or an idle state, the radiator fan 2 operates to force air extraction, and at the same time, the baffle 4 blocks the gap 5 between the radiator and the radiator fan 2 and forces the air flow to pass through the radiator.

[0079] S2 Cooling at high speed. When the all-terrain vehicle is in a high-speed state, the radiator fan 2 is fixed on the rear air outlet surface 103 of the radiator body 1 through the mounting frame 3, and the natural wind efficiently dissipates heat through the radiator.

[0080] S3 Pre-filtration. The filter plate in the pre-filtration mechanism filters the natural wind flowing into the radiator, the radiator fan 2, and the engine system.

[0081] S4 Cleaning the blocked filter plate. After judging the blockage condition of the filter plate, when the filter plate is in a blocked state, the cleaning roller 7 moves reciprocally to clean the filtering surface of the filter plate.

[0082] S4 further includes:

[0083] S40 Preset a reference current value according to the filter plate type;

[0084] S41 Obtain the humidity value of the environment where the radiator device is located;

[0085] S42 Obtain the wind speed value between the pre-filter structure 6 and the radiator;

[0086] S43 Obtain the current determination threshold corresponding to the humidity value and the wind speed value;

[0087] S44 Obtain the real-time current value;

[0088] S44 Judge the blockage situation according to the measured current value and the current determination threshold. When the current > 0.9 times the threshold, the cleaning roller 7 performs a cleaning on the filtering surface of the filter plate. When the current ≤ 0.7 times the threshold, a forced alarm is given and the speed is reduced to protect the fan. At the same time, the cleaning roller 7 performs multiple cleanings on the filtering surface of the filter plate.

[0089] Moreover, it further 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 side or the air outlet side of the filter plate. It also includes a low-power MCU (such as STM32) for processing multi-sensor data and running a determination algorithm. Preferably, differential pressure sensors can also be arranged on both sides of the filter plate. Optionally, the formula for the current determination threshold is: Final threshold = (X - Y) × K, where X is the first reference setting value (such as 20 mA, preset according to the wind speed gear), Y is the humidity compensation value (such as Y = 3 mA at high humidity), 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).

[0090] In this embodiment, by using the radiator device through the above method, it is possible to maintain a high heat dissipation efficiency both in the high-speed state and the low-speed state of the all-terrain vehicle. At the same time, through the pre-filter, it can effectively keep the radiator main body 1 and the engine system clean. During the use of the filter plate, even in the complex environment where the all-terrain vehicle is located, the pre-filter structure 6 can automatically clean according to the blockage situation, thus maintaining the working stability of the radiator device.
