Description

Technical Field

[0001] This utility model relates to the field of wheel rim heat dissipation technology, and in particular to an intelligent heat dissipation wheel rim mechanism. Background Technology

[0002] Wheel rims are an essential component of a vehicle's structure. Their primary function is to support and secure the tires, ensuring a tight fit between the tire and the wheel, thereby guaranteeing vehicle safety and performance. Wheel rims not only bear the weight of the vehicle and the various forces and torques generated during driving, but also play a role in mitigating impacts, reducing vibrations, and ensuring ride smoothness. Furthermore, the design and selection of wheel rims significantly influence vehicle handling, stability, and fuel economy.

[0003] Frequent and prolonged braking can cause the brakes and tires to overheat due to the small space and poor ventilation between the wheels and rims, making it difficult for the heat generated during braking to dissipate. Furthermore, this high temperature can significantly reduce the brake's coefficient of friction, leading to brake fade. If braking is prolonged, the intense heat generated by the brakes can also cause them to crack; additionally, this heat can be directly transferred to the tires, potentially triggering a tire blowout.

[0004] To address the issue of poor braking performance and even tire blowouts caused by prolonged or frequent braking, existing technologies have incorporated automatic water-cooling devices into vehicle brake systems. However, water cooling can lead to tire aging and a risk of blowouts, and may also reduce the friction coefficient of brake pads, affecting braking performance. In cold regions, water cooling can easily cause road surfaces to freeze, compromising driving safety.

[0005] Therefore, in order to solve the problem of poor braking performance or even tire blowout caused by prolonged or frequent braking, it is necessary to provide a highly safe and intelligent heat dissipation rim mechanism to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide an intelligent heat dissipation rim mechanism, the specific technical solution of which is as follows: An intelligent heat dissipation rim mechanism includes a rim assembly and an intelligent heat dissipation component; The rim assembly includes an inner rim ring, an outer rim ring, and rim spokes; the inner rim ring and the outer rim ring are coaxially arranged and connected to each other by the rim spokes; The intelligent heat dissipation component includes an openable heat dissipation mechanism and a telescopic drive component. The openable heat dissipation mechanism is disposed in the circumferential gap between the inner and outer rings of the wheel rim, and includes multiple heat dissipation blades rotatably disposed in the circumferential gap. There is an overlap area between each pair of adjacent heat dissipation blades, and in the direction of rotational opening of the heat dissipation blades, the preceding heat dissipation blade overlaps the underside of the following heat dissipation blade. A rotation space is reserved between the heat dissipation blades and the wheel rim spokes. The telescopic drive component is at least two in number and is symmetrically arranged along the outer ring of the wheel rim for driving the heat dissipation blades to rotate. Each telescopic drive component is connected to a vehicle controller disposed on the vehicle.

[0007] Optionally, the openable heat dissipation mechanism further includes an inner connecting ring and an outer connecting ring; the inner connecting ring is coaxially disposed on the outer wall of the inner ring of the rim; the outer connecting ring is coaxially disposed on the inner wall of the outer ring of the rim; each of the heat dissipation blades can be rotatably disposed in the radial direction from the inner connecting ring to the outer connecting ring.

[0008] Optionally, the end of each heat dissipation blade connected to the inner connecting ring is a ball joint; the end of each heat dissipation blade connected to the outer connecting ring is also a ball joint.

[0009] Optionally, the fixed end of each of the telescopic drive components is disposed on the outer connecting ring, while the telescopic end is connected to the heat dissipation blade, and its telescopic direction is arranged parallel to the axial direction of the outer connecting ring; each of the telescopic drive components is symmetrically arranged along the outer connecting ring.

[0012] Optionally, the intelligent heat dissipation component further includes a temperature sensor; the temperature sensor is disposed on the wheel rim of the vehicle with brake discs and is connected to the vehicle controller.

[0013] Optionally, the vehicle controller is a vehicle ECU.

[0014] The application of the technical solution of this utility model has at least the following beneficial effects: This invention provides an intelligent heat-dissipating wheel rim mechanism. A vehicle controller manages the extension of the telescopic ends of each telescopic drive component, which in turn triggers the gradual rotation and opening of each heat dissipation blade, increasing airflow and achieving rapid heat dissipation. This also enables intelligent control of the heat dissipation blade opening, thus solving the problem of poor braking performance or even tire blowouts caused by prolonged or frequent braking. Specifically, in the direction of the heat dissipation blade rotation, the preceding heat dissipation blade overlaps the following heat dissipation blade, facilitating the gradual linkage of adjacent heat dissipation blades to open with a small number of telescopic drive components, achieving energy savings. The number of telescopic drive components is at least two, symmetrically arranged along the outer rim, ensuring uniform transmission of driving force and guaranteeing the safe and stable opening of the heat dissipation blades for rapid heat dissipation. Therefore, compared to existing automatic water-spraying cooling devices added to vehicle brakes, the intelligent heat-dissipating wheel rim mechanism provided by this invention offers higher safety.

[0020] Example: See Figures 1-5 An intelligent heat dissipation rim mechanism includes a rim assembly 1 and an intelligent heat dissipation assembly 2; The rim assembly 1 includes an inner rim ring 1.1, an outer rim ring 1.2, and rim spokes 1.3; the inner rim ring 1.1 and the outer rim ring 1.2 are coaxially arranged and connected to each other by the rim spokes 1.3. The intelligent heat dissipation component 2 includes an openable heat dissipation mechanism and a telescopic drive component 2.1. The openable heat dissipation mechanism is disposed in the circumferential gap between the inner ring 1.1 and the outer ring 1.2 of the rim, and includes a plurality of (specifically twelve) heat dissipation blades 2.3 rotatably disposed in the circumferential gap. There is an overlap area between each pair of adjacent heat dissipation blades 2.3, and in the direction of rotational opening of the heat dissipation blades 2.3, the preceding heat dissipation blade 2.3 overlaps (but does not connect) below the following heat dissipation blade 2.3, which facilitates the gradual linkage of adjacent heat dissipation blades 2.1 with the use of a small number of telescopic drive components 2.1. .3 The radiator blades 2.3 rotate to open, achieving energy-saving effects; a rotation space is reserved between the radiator blades 2.3 and the rim spokes 1.3 to ensure that each radiator blade rotates and opens smoothly; the number of telescopic drive components 2.1 is at least two (specifically four can be selected), and they are symmetrically arranged along the outer ring 1.2 of the rim, used to drive the radiator blades 2.3 to rotate, and to ensure uniform transmission of driving force, ensuring that the radiator blades 2.3 open safely and stably, achieving a rapid heat dissipation effect; each of the telescopic drive components 2.1 is connected to the vehicle controller B (specifically the vehicle ECU) installed on the vehicle, which facilitates intelligent control of the opening and heat dissipation of the radiator blades 2.3.

[0021] The openable heat dissipation mechanism further includes an inner connecting ring 2.4 and an outer connecting ring 2.5; the inner connecting ring 2.4 is coaxially disposed on the outer wall of the inner ring 1.1 of the rim; the outer connecting ring 2.5 is coaxially disposed on the inner wall of the outer ring 1.2 of the rim; each of the heat dissipation blades 2.3 is rotatably disposed in the radial direction from the inner connecting ring 2.4 to the outer connecting ring 2.5. The combination of the inner connecting ring 2.4 and the outer connecting ring 2.5 in this embodiment facilitates the improvement of the overall rigidity of the openable heat dissipation mechanism.

[0022] The end of each heat dissipation blade 2.3 connected to the inner connecting ring 2.4 is a ball joint; the end of each heat dissipation blade 2.3 connected to the outer connecting ring 2.5 is also a ball joint.

[0023] The fixed end of each telescopic drive component 2.1 is disposed on the outer connecting ring 2.5, while the telescopic end is connected to the heat dissipation blade 2.3. Its telescopic direction is parallel to the axial direction of the outer connecting ring 2.5, which facilitates the opening and closing of the heat dissipation blade 2.3. Each telescopic drive component 2.1 is symmetrically arranged along the outer connecting ring 2.5 to ensure uniform transmission of driving force, ensure that the heat dissipation blade 2.3 opens safely and stably, and achieves a rapid heat dissipation effect.

[0024] The telescopic drive component 2.1 includes a hydraulic telescopic rod or an electric telescopic rod, such as an electric telescopic rod.

[0025] The number of rim spokes 1.3 is multiple (specifically twelve), and they are all arranged in the radial direction from the inner rim 1.1 to the outer rim 1.2, which facilitates the enhancement of the connection rigidity between the inner rim 1.1 and the outer rim 1.2, and ensures the uniform transmission of driving force, braking force and lateral torque to the wheel.

[0026] The intelligent heat dissipation component 2 also includes a temperature sensor 2.2; the temperature sensor 2.2 is installed on the wheel rim of the vehicle with brake disc and connected to the vehicle controller B, so as to collect the temperature data of the wheel rim with brake disc in real time and transmit it to the vehicle controller B in real time, and then the vehicle controller B determines whether to generate a heat dissipation command.

[0027] The working principle of the intelligent heat dissipation rim mechanism is as follows: The temperature sensor 2.2 is used to collect the temperature data of the wheel edge with the brake disc in real time and transmit it to the vehicle controller B in real time. During the braking process of the vehicle braking system A controlling the brake disc, the real-time temperature data collected by the vehicle controller B determines whether to generate a heat dissipation command (if the temperature is higher than the temperature control threshold, a heat dissipation command is generated; this determination process is the conventional control logic of the vehicle controller B). If a heat dissipation command is generated, the vehicle controller B controls the telescopic ends of each telescopic drive component 2.1 to extend parallel to the axial direction of the outer connecting ring 2.5, thereby stably linking each heat dissipation blade 2.3 to gradually rotate and open, increasing airflow, and thus achieving a rapid heat dissipation effect.
