Description

Technical Field

[0001] The invention relates to the field of lightweight steel rims, and in particular to a lightweight steel rim with high flow rate heat dissipation. Background Art

[0002] Steel rims are one of the indispensable accessories in the automotive field. Automobile steel rims are mainly used in the processing and manufacturing of automobile hubs. In the field of automobile hub processing technology, automobile steel rims need to be processed. With the vigorous development of the automobile industry, new energy, energy conservation, environmental protection and other directions are the development trends of automobiles. For this reason, the automobile industry pays more and more attention to the research on lightweight automobiles, among which the lightweight of wheels is the focus of research. With the continuous improvement of customer requirements, the weight of steel rims can no longer meet customer needs.

[0003] The Chinese patent with announcement number CN214240279 U provides a lightweight steel rim, in which the rim is made of steel with a tensile strength greater than 780Mpa, the width W1 is 258-260mm, and the thickness D is 3.6-3.8mm. Preferably, the spoke is made of high-strength alloy steel with a tensile strength greater than 440Mpa, and the width W2 of the spoke is 115-117mm. By improving the rim material, reducing the rim thickness, and changing the shape and size of the ventilation holes, the purpose of further reducing the weight of the steel rim is achieved while ensuring the strength of the steel rim.

[0004] Automobile steel rims are components installed on cars to support tires. Existing tires will generate a lot of heat during long-term work, which will cause the temperature of the tires themselves to be high. The temperature on the tires will also cause the temperature of the steel rims to rise. Under long-term high temperatures, the steel rims are very likely to deform, which will shorten the overall service life of the steel rims and affect the braking effect of the car to a certain extent, which will lead to dangerous accidents. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a lightweight steel rim with high flow rate heat dissipation to solve the technical problem that the temperature on the tire will also cause the temperature of the steel rim to rise, and the steel rim is very likely to deform under high temperature for a long time, thereby shortening the overall service life of the steel rim and affecting the braking effect of the car to a certain extent.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lightweight steel rim with high flow rate heat dissipation, comprising a rim and spokes, wherein a plurality of spokes are arranged on the inner side of the rim, and one end of each spoke is connected to a heat sink, wherein the spokes are hollow, and an inner cavity is formed on the inner wall thereof, and a plurality of reinforcing ribs are installed in the inner cavity thereof, wherein the reinforcing ribs are arranged in an inverted trapezoidal shape as a whole;

[0007] A ventilation hole is provided at the center of the heat sink, a heat dissipation cavity is provided on the inner wall of the reinforcing rib, one end of the heat dissipation cavity is connected to the ventilation hole, and a heat-conducting column is elastically provided on the inner wall of the heat-conducting cavity, and the overall length of the heat-conducting column is smaller than the overall length of the heat dissipation cavity.

[0008] By adopting the above technical scheme, the wheel spoke itself is hollow, which effectively reduces the overall mass of the rim itself and achieves the purpose of lightweighting the vehicle wheel hub. In addition, the multiple groups of reinforcing ribs are arranged in an inverted trapezoidal shape as a whole, which ensures the lightweight of the steel ring while improving the overall strength of the rim. During the rotation of the rim, the heat of the guide column itself will be thrown toward the outer wall under the action of centrifugal force. At this time, the heat on the rim is discharged into the heat dissipation cavity through the heat-conducting column. At the same time, the external cold air will take away the heat in the heat dissipation cavity when passing through the ventilation holes, thereby achieving heat dissipation and cooling of the entire rim, increasing the overall service life of the rim and ensuring that the rim will not deform when working for a long time.

[0009] The present invention is further configured such that a sealing ring is connected to one end of the heat-conducting column located in the heat dissipation cavity, and the sealing ring seals the heat dissipation cavity under normal conditions.

[0010] Preferably, under normal conditions, the sealing ring at the bottom of the guide column heat will seal the heat dissipation cavity to prevent external dust from entering and affecting the thermal conductivity of the guide column heat. During the rotation of the rim, the elastic component is in a compressed state. After the heat conduction is completed, the sealing ring is driven to reset and slide in the heat dissipation cavity under the action of the elastic component. During this process, the sealing rubber ring will clean the inner wall of the heat dissipation cavity to prevent the subsequent blockage of the heat dissipation cavity, thereby improving the subsequent overall heat dissipation effect.

[0011] The present invention is further configured such that an elastic component is slidably arranged in the heat dissipation cavity, and one end of the elastic component is connected to the heat-conducting column.

[0012] Preferably, during the rotation of the rim, the heat-conducting column is thrown outward by centrifugal force, during which the elastic component itself is deformed. Subsequently, after the rim stops rotating, the heat-conducting column is reset and slid by the reset action of the elastic component.

[0013] The present invention is further configured such that a first spoke and a second spoke are provided on one side of the rim, and an air guide groove is provided on the second spoke.

[0014] Preferably, the compressive strength of the rim edge is improved by the action of the first spoke and the second spoke. The indirect setting not only makes the weight of the steel ring itself lighter, but also realizes more separation space. During the rotation of the rim, the nearby air will also be discharged through the air guide groove, thereby greatly reducing the wind resistance during the rotation of the rim and improving the overall practicality of the device.

[0015] The present invention is further configured such that an outer wall of the heat sink is evenly provided with a plurality of arc-shaped flow channels, and an inner wall of the arc-shaped flow channels is configured to be smooth.

[0016] Preferably, the arc-shaped flow channel is provided to facilitate the flow of wind to one side during the flow, which not only reduces the wind resistance at the heat sink, but also effectively reduces the noise of the outer wall of the heat sink, thereby improving the overall working environment.

[0017] The present invention is further configured such that the heat-conducting column itself is formed in one piece with a flexible material, and there is smooth contact between its outer wall and the heat dissipation cavity.

[0018] Preferably, the thermally conductive column itself is made of a flexible silicone sheet, which has good thermal conductivity, further improving the overall thermal conductivity effect. The smooth setting between the two effectively reduces the sliding friction between the thermally conductive column and the heat dissipation cavity, making it easier for the thermally conductive column to slide stably in the heat dissipation cavity.

[0019] The present invention is further configured such that the front ends of the first spoke and the second spoke are both manufactured using a bevel chamfering process.

[0020] Preferably, the chamfered angles are made to effectively reduce the wind resistance of the first spoke and the second spoke, thereby improving the overall working environment of the steel rim.

[0021] The present invention is further configured such that the elastic component includes a sliding block, a sliding groove and a reset spring, one side of the heat-conducting column is connected to the sliding block, the sliding block slides in the sliding groove, and the top end of the sliding block is connected to the reset spring.

[0022] Preferably, the sliding block is located inside the sliding groove. When the rim rotates, the heat-conducting column will drive the sliding block to slide to one side. At the same time, the sliding block will drive the reset spring to be compressed. During this process, the reset spring is in a compressed state. When the rim stops rotating subsequently, the reset spring in the compressed state will reset, thereby driving the heat-conducting column to reset and slide.

[0023] The present invention is further configured such that the spoke is located at a middle position of the inner wall of the rim.

[0024] Preferably, the middle position facilitates the compression resistance of the entire rim, thereby further improving the overall strength of the rim.

[0025] The present invention is further configured such that one end of the wheel strip fits with the arc-shaped flow channel of the outer wall of the heat sink.

[0026] As a preferred embodiment, the wind is effectively prevented from passing through the contact surface between the wheel spokes and the heat sink, thereby reducing the noise generated by the wind during the operation of the rim.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention evenly arranges a plurality of spokes in the rim, and the spokes themselves are hollow, which effectively reduces the overall mass of the rim itself and achieves the purpose of lightweighting the vehicle wheel hub. In addition, a plurality of reinforcing ribs are arranged in the spokes, and the plurality of reinforcing ribs are arranged in an inverted trapezoidal shape as a whole, which ensures the lightweighting of the steel ring and improves the overall strength of the rim.

[0029] 2. The present invention provides a ventilation hole at the center of the heat sink. When the rim itself rotates, the surrounding air pressure increases, causing the gas to pass through the ventilation hole and be discharged to one side. Since a heat dissipation cavity is provided in the reinforcing rib, and a heat-conducting column is slidably provided on the inner wall thereof, the heat of the heat-conducting column itself will be thrown toward the outer wall under the action of centrifugal force during the rotation of the rim. At this time, the heat on the rim is discharged into the heat dissipation cavity through the heat-conducting column. At the same time, the external cold air will take away the heat in the heat dissipation cavity when passing through the ventilation hole, thereby achieving heat dissipation and cooling of the entire rim, thereby increasing the service life of the entire rim and ensuring that the rim will not deform when working for a long time.

[0030] 3. The present invention provides an elastic component on one side of the heat-conducting column. Under normal conditions, the sealing ring at the bottom of the heat-conducting column will seal the heat-dissipating cavity, preventing external dust from entering and affecting the thermal conductivity of the heat-conducting column. During the rotation of the rim, the elastic component is in a compressed state. After the heat conduction is completed, the sealing ring is driven to reset and slide in the heat-dissipating cavity under the action of the elastic component. During this process, the sealing rubber ring will clean the inner wall of the heat-dissipating cavity, preventing the subsequent blocking of the heat-dissipating cavity, thereby improving the subsequent overall heat dissipation effect.

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The following describes an embodiment of the present invention based on its overall structure.

[0044] First embodiment:

[0045] See also Figure 1-Figure 9 A lightweight steel rim with high-speed heat dissipation shown in the figure includes a rim 1, a spoke 3, a spoke assembly, a heat dissipation mechanism, a reset mechanism and a heat conduction assembly. An array of spokes 3 are arranged on the inner side of the rim 1, and one end of the spoke 3 is connected to a heat dissipation member 7, and the spoke 3 is located in the middle position of the inner wall of the rim 1. The middle position is convenient for resisting the pressure of the rim 1 as a whole, and further improves the overall strength of the rim 1. The spoke 3 itself is a hollow setting, and an inner cavity 10 is opened on its inner wall. The inner cavity 10 effectively reduces the rim 1 The overall mass of the wheel hub is improved to achieve the purpose of lightweighting the vehicle wheel hub, and three groups of reinforcing ribs 12 are installed in the inner cavity 10 thereof, wherein the reinforcing ribs 12 are arranged in an inverted trapezoidal shape as a whole, and the lightweight of the steel ring is ensured under the action of the reinforcing ribs 12 while improving the overall strength of the wheel rim, wherein the inner wall of the reinforcing ribs 12 is provided with a heat dissipation cavity 9, and the inner wall of the heat dissipation cavity 9 is elastically provided with a heat conducting column 11, and during the rotation of the wheel rim 1, the heat conducting column 11 in the heat dissipation cavity 9 is thrown toward the outer wall under the action of centrifugal force;

[0046] At this time, one end of the heat-conducting column 11 will contact the inner side of the rim 1, and under the action of the heat-conducting column 11, the heat on the rim 1 will be discharged into the heat dissipation cavity 9. Since the overall length of the heat-conducting column 11 is smaller than the overall length of the heat-dissipating cavity 9, the heat will be gathered in the heat-dissipating cavity 9, and a ventilation hole 8 is provided at the center of the heat dissipating member 7, and one end of the heat-dissipating cavity 9 is connected to the ventilation hole 8. During the rotation of the rim 1, the air flow rate near the rim 1 will be accelerated, which will cause the external cold air to be discharged to one side through the ventilation hole 8. Since one end of the heat-dissipating cavity 9 is connected to the ventilation hole 8, the high-speed flowing cold air will take away the heat in the heat-dissipating cavity 9, thereby realizing rapid heat dissipation of the rim 1, improving the overall service life of the rim 1, and ensuring that the rim 1 will not be deformed when working for a long time, and when the wind passes through the ventilation hole 8, it will not impact the heat-conducting column 11 itself, thereby extending the service life of the heat-conducting column 11 itself;

[0047] An elastic component 14 is slidably arranged in the heat dissipation cavity 9, and one end of the elastic component 14 is connected to the heat-conducting column 11. During the rotation of the rim 1, the heat-conducting column 11 is thrown outward by centrifugal force. During this process, the elastic component 14 itself is deformed. After the rim 1 stops rotating, the heat-conducting column 11 is reset and slid under the reset action of the elastic component 14. An array of arc flow channels 2 are evenly arranged on the outer wall of the heat sink 7, and the inner wall of the arc flow channel 2 is smoothly arranged. The arrangement of the arc flow channel 2 facilitates the wind to flow to one side through it during the flow of wind, which not only reduces the wind resistance at the heat sink 7, but also effectively reduces the noise of the outer wall of the heat sink 7, thereby improving the overall working environment.

[0048] In the above embodiments, please refer to Figure 1 and Figure 3 A first spoke 4 and a second spoke 5 are provided on one side of the rim 1, and an air guide groove 6 is provided on the second spoke 5. The compressive strength of the edge of the rim 1 is improved by the action of the first spoke 4 and the second spoke 5. The indirect setting not only makes the weight of the steel ring itself lighter, but also realizes more separation space. During the rotation of the rim 1, the nearby air will also be discharged through the air guide groove 6, thereby greatly reducing the wind resistance during the rotation of the rim 1 and improving the overall practicality of the device. At the same time, the front ends of the first spoke 4 and the second spoke 5 are made by a bevel chamfering process. The chamfering process effectively reduces the wind resistance of the first spoke 4 and the second spoke 5 and improves the overall working environment of the steel ring.

[0049] In the above embodiments, please refer to Figure 8The elastic component 14 includes a sliding block, a sliding groove and a reset spring. The elastic component 14 is connected to the sliding block on one side of the heat-conducting column 11, and the sliding block is located in the sliding groove for sliding, and is located at the top of the sliding block and is connected to the reset spring. The sliding block is located inside the sliding groove. When the rim 1 rotates, the heat-conducting column 11 will drive the sliding block to slide to one side, and the sliding block will drive the reset spring to be compressed. During this process, the reset spring is in a compressed state. When the rim 1 stops rotating subsequently, the reset spring in the compressed state will reset, thereby driving the heat-conducting column 11 to reset and slide.

[0050] Second embodiment:

[0051] See also Figure 4 A lightweight steel rim with high-flow rate heat dissipation is shown, and its overall structure is similar to that of the first embodiment, wherein a heat-conducting column 11 is located at one end of a heat-dissipating cavity 9 and is connected to a sealing ring 13. Under normal conditions, the sealing ring 13 blocks the heat-dissipating cavity 9 to prevent external dust from entering and affecting the thermal conductivity of the heat-conducting column 11. During the rotation of the rim 1, the elastic component 14 is in a compressed state. At this time, the sealing ring 13 releases the blocking work on the heat-dissipating cavity 9. At this time, the heat in the heat-dissipating cavity 9 can be discharged outwardly under the action of the ventilation holes 8, thereby completing the heat dissipation work of the entire rim. After the subsequent heat conduction is completed, the sealing ring 13 is driven to reset and slide in the heat-dissipating cavity 9 under the action of the elastic component 14. In this process, while completing the blocking of the heat-dissipating cavity 9, the sealing ring 13 will clean the inner wall of the heat-dissipating cavity 9, so that the dust and impurities in the heat-dissipating cavity 9 are discharged under the action of the sealing ring 13, thereby preventing the subsequent blocking of the heat-dissipating cavity 9, and further improving the subsequent overall heat dissipation effect.

[0052] In the above embodiments, please refer to Figure 4 The heat-conducting column 11 itself is an integrally formed flexible material, and there is a smooth contact between its outer wall and the heat dissipation cavity 9. The heat-conducting column 11 itself is made of a flexible silicone sheet, which has good thermal conductivity, further improving the overall thermal conductivity effect. The smooth setting between the two effectively reduces the sliding friction between the heat-conducting column 11 and the heat-dissipating cavity 9, making it easier for the heat-conducting column 11 to slide stably in the heat-dissipating cavity 9.

[0053] The present invention is in specific operation: when in use, the wheel spoke 3 on the inner side of the rim 1 will improve the overall compressive strength of the rim 1, and the interior of the wheel spoke 3 is hollow, and this design effectively reduces the gravity of the rim 1 itself, achieving the purpose of lightweighting the vehicle wheel hub, and three groups of reinforcing ribs 12 are arranged inside the wheel spoke 3, and the three groups of reinforcing ribs 12 are arranged in an inverted trapezoidal shape as a whole, which ensures the lightweight of the steel ring while improving the overall strength of the rim 1. During operation, the rim 1 will rotate rapidly, and since a heat-conducting column 11 is slidingly arranged on the inner wall of the reinforcing rib 12, the heat-conducting column 11 is thrown toward the outer wall through the centrifugal force of the rim 1 itself during rotation, until it contacts the rim 1. In this process, the heat generated during the operation of the rim 1 is discharged into the heat dissipation cavity 9 through the heat-conducting column 11;

[0054] In addition, one end of the wheel spoke 3 is connected to the heat sink 7, and a ventilation hole 8 is provided at the center of the heat sink 7. When the steel ring rotates and translates, the air flow rate on one side of the rim 1 is accelerated, and the external cold air will be discharged to one side through the ventilation hole 8. Since one end of the heat dissipation cavity 9 is connected to the ventilation hole 8, the high-speed flowing cold air will take away the heat in the heat dissipation cavity 9, thereby realizing rapid heat dissipation of the rim 1, improving the overall service life of the rim 1, and ensuring that the rim 1 will not be deformed when working for a long time.

[0055] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
