Description

Technical Field

[0001] The utility model relates to the field of automotive parts, in particular to a rim structure and a vehicle having the same. Background Art

[0002] The vehicle brakes by clamping the brake disc with a brake caliper. The brake fluid is output from an oil pot to the brake caliper. The brake fluid provides pressure to push out the piston, driving the friction pads on the brake caliper to rub against the brake disc, so that the vehicle gradually decelerates or stops. When the brake caliper clamps and the friction pads rub against the brake disc, intense heat will be generated. The brake disc and the caliper absorb the heat, which will cause the brake disc and the caliper to deform, and the material properties of the friction pads to decay, thus affecting the braking performance of the brake and the driving experience of the driver.

[0003] The brake disc and the brake caliper are installed on the rim structure. The conventional rim structure is specially designed to reduce wind resistance, minimizing the amount of air entering the rim, thereby reducing the air resistance during driving and meeting the requirement of reducing energy consumption. However, this design reduces air flow, so that the heat of the brake disc, the caliper and the friction pads during braking stays on the parts themselves for a long time, resulting in relatively high temperatures of the brake disc, the caliper and the friction pads.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated in this description is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred components or elements must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] Please refer to Figure 1, A rim structure provided by the present utility model includes a rim 10, a wheel spoke 20, a hub 30, a decorative cover 40, a power device 50, and a transmission device 60. The rim 10 and the hub 30 are coaxially arranged, and the rim 10 is disposed outside the hub 30. A plurality of wheel spokes 20 are provided between the rim 10 and the hub 30. The plurality of wheel spokes 20 are radially arranged and spaced along the circumferential direction of the rim 10. The decorative cover 40 is rotatably disposed between two adjacent wheel spokes 20. The decorative cover 40 is disposed between two adjacent wheel spokes 20 and can be switched between a first state and a second state. When the decorative cover 40 is in the first state, the decorative cover 40 is arranged side by side with the wheel spoke 20. During the process of the decorative cover 40 switching from the first state to the second state, the decorative cover 40 rotates relative to the wheel spoke 20, and a gap is formed between the decorative cover 40 and the wheel spoke 20. The power device 50 is connected to the transmission device 60, and the transmission device 60 is connected to the decorative cover 40. During the process of the decorative cover 40 switching from the first state to the second state, the power device 50 drives the decorative cover 40 to rotate relative to the wheel spoke 20 through the transmission device 60. It should be noted that the first state refers to the normal driving state of the vehicle, and the second state refers to the braking state of the vehicle. The rim structure provided by the present utility model enables the decorative cover 40 to move freely when the vehicle is moving. When the vehicle brakes, the power device 50 pushes the transmission device 60 to rotate. During the rotation of the transmission device 60, the decorative cover 40 is driven to rotate relative to the wheel spoke 20, so that a gap is formed between the decorative cover 40 and the wheel spoke 20, introducing air flow, thereby accelerating the air convection inside the rim 10, taking away the high temperature generated by the friction between the brake disc and the caliper, and ensuring the braking performance and driving experience of the vehicle; when the vehicle is driving normally, the power device 50 can push the transmission device 60 to rotate in the reverse direction. During the rotation of the transmission device 60, the decorative cover 40 is reset, and the gap between the wheel spoke 20 and the decorative cover 40 is closed, reducing the amount of air entering the rim 10, reducing the wind resistance during driving, and achieving the purpose of reducing energy consumption.

[0025] Please refer to Figure 2 and Figure 3 , The shape and area of the decorative cover 40 are substantially equivalent to the shape and area of the space between two adjacent wheel spokes 20. In this way, when the decorative cover 40 does not rotate, it can be arranged side by side with the wheel spokes 20 on both sides, reducing the amount of air entering the rim 10. When the decorative cover 40 rotates relative to the wheel spoke 20, a gap can be formed between the decorative cover 40 and the wheel spokes 20 on both sides, introducing air flow.

[0026] Furthermore, a rotating shaft 41 is provided on the decorative cover 40. The rotating shaft 41 passes through the decorative cover 40 and is fixedly connected to the decorative cover 40. Both ends of the rotating shaft 41 are rotatably connected to the rim 10 and the hub 30 respectively. The bottom of the rotating shaft 41 is connected to the transmission device 60. During the rotation of the transmission device 60, the decorative cover 40 can be driven to rotate and reset through the rotating shaft 41.

[0027] In an embodiment of the present utility model, a flow channel is provided inside the wheel hub 30, and both ends of the flow channel are respectively communicated with an oil pot and a power device 50. Please refer to Figure 4 together. The power device 50 includes a housing 51 and a cavity 52 located inside the housing 51. The cavity 52 extends along the length direction of the housing 51. The cavity 52 is communicated with the flow channel. A spring 53 and a piston 54 are provided inside the cavity 52. The piston 54 is hermetically connected to the inner wall of the housing 51. The spring 53 is in an un-stretched state. One end of the spring 53 is connected to the inner wall of the cavity 52, and the other end is connected to the piston 54. The piston 54 is connected to a transmission device 60. A pipe 55 is provided at one end of the housing 51 away from the transmission device 60. The cavity 52 is communicated with the flow channel inside the wheel hub 30 through the pipe 55.

[0028] Further, in an embodiment of the present invention, the transmission device 60 may include a rack 61, a first gear 62, a second gear 63 and a third gear 64. The rack 61 is connected to the piston 54. The first gear 62 is coaxially arranged with the rotating shaft 41. The second gear 63 is coaxially arranged with the third gear 64, and the radius of the second gear 63 is smaller than that of the third gear 64. The second gear 63 meshes with the rack 61, and the third gear 64 meshes with the first gear 62. That is, when the rack 61 moves, it will drive the second gear 63 to rotate. The second gear 63 drives the third gear 64 to rotate. The third gear 64 drives the first gear 62 to rotate. The first gear 62 drives the rotating shaft 41 and the decorative cover 40 to rotate. In this embodiment, when the vehicle brakes, the brake fluid in the oil pot will enter the pipeline 55 through the flow channel, and then enter the cavity 52 of the housing 51. As the amount of oil fluid continuously increases, the oil fluid pushes the piston 54 to move, and the spring 53 is stretched. During the movement of the piston 54, it drives the rack 61 to move, drives the second gear 63 to rotate, and further drives the third gear 64 to rotate, and then drives the rotating shaft 41 to rotate. The rotating shaft 41 drives the decorative cover 40 to rotate relative to the wheel spoke 20, so as to form a gap between the decorative cover 40 and the wheel spoke 20 to introduce air flow, thereby accelerating the air convection in the rim 10 and taking away the high temperature generated by the friction of the brake disc and the caliper; during the driving process of the vehicle, the brake fluid in the flow channel will be withdrawn. When the thrust of the oil fluid disappears, the piston 54 will be pulled back to its original position by the elastic force of the spring 53. The rack 61 follows the reset, drives the second gear 63, the third gear 64 and the first gear 62 to rotate in the reverse direction. The rotating shaft 41 follows the first gear 62 to rotate in the reverse direction, drives the decorative cover 40 to reset, and is basically in contact with the two side wheel spokes 20, reducing the amount of air entering the rim 10 and reducing the wind resistance during the driving process, so as to achieve the purpose of reducing energy consumption. In this embodiment, the setting of the second gear 63 and the third gear 64 forms a speed reduction mechanism between the rack 61 and the first gear 62. When the thrust generated by the brake fluid is too large, it can reduce the rotation speed of the decorative cover 40 and reduce the opening degree of the decorative cover 40. It should be noted that the number of gears in the transmission device 60 is not limited and can be set according to actual needs.

[0029] For example, in an embodiment of the present invention, the transmission device 60 may include a rack 61 and a first gear 62, that is Figure 2 and Figure 3The second gear 63 and the third gear 64 are removed, and this embodiment can be applied when the thrust generated by the brake fluid is not large. Among them, the rack 61 passes through the housing 51 and is connected to the piston 54, and the first gear 62 is coaxially arranged with the rotating shaft 41, and the first gear 62 is meshed with the rack 61. In this embodiment, when the vehicle brakes, brake fluid in the oil reservoir flows through the flow channel into the pipe 55 and then into the cavity 52 of the housing 51. As the amount of fluid increases, the fluid pushes the piston 54 to move, stretching the spring 53. During the movement of the piston 54, the rack 61 moves, driving the first gear 62 to rotate, thereby driving the rotating shaft 41 to rotate. The rotating shaft 41 drives the decorative cover 40 to rotate relative to the spokes 20, creating a gap between the decorative cover 40 and the spokes 20 to introduce airflow, thereby accelerating air convection within the rim 10 and removing the high temperature generated by the friction between the brake disc and the caliper. During driving, the brake fluid in the flow channel withdraws. When the fluid thrust disappears, the piston 54 is pulled back to its original position by the elastic force of the spring 53. The rack 61 then returns to its original position, driving the first gear 62 to rotate in the opposite direction. The rotating shaft 41 then rotates in the opposite direction with the first gear 62, driving the decorative cover 40 to return to its original position, substantially fitting the spokes 20 on both sides. This reduces the amount of air entering the rim 10, reduces wind resistance during driving, and achieves the purpose of reducing energy consumption.

[0030] In one embodiment of the present invention ( Figures 1-4 (not shown), the power device 50 may include a motor, a controller, and a sensing device. The transmission device 60 may include a turbine, a worm, and a first gear 62. The motor is arranged on the wheel hub 30, and the output shaft of the motor is connected to the worm, the worm is engaged with the turbine, and the turbine is engaged with the first gear 62. The first gear 62 is coaxially arranged with the rotating shaft 41. The sensing device is arranged on the pedal, and the controller is respectively connected to the sensing device and the motor signal. In this embodiment, when the vehicle brakes, the sensing device transmits a braking signal to the controller, and the controller controls the motor to rotate, driving the worm gear to rotate, and then driving the first gear 62, the rotating shaft 41 and the decorative cover 40 to rotate, so that a gap is formed between the decorative cover 40 and the spoke 20 to introduce airflow, thereby accelerating air convection in the rim 10 and taking away the high temperature generated by the friction between the brake disc and the caliper; similarly, when the vehicle is driving, the sensing device transmits a driving signal to the controller, and the controller controls the motor to rotate in the opposite direction, adjusting the worm gear to rotate in the opposite direction, and then driving the first gear 62, the rotating shaft 41 and the decorative cover 40 to rotate in the opposite direction, and the decorative cover 40 is reset and basically fits with the spoke 20, thereby reducing the amount of air entering the rim 10, reducing the wind resistance during driving, and achieving the purpose of reducing energy consumption.

[0031] As can be known from the above description, a rim structure provided by the present utility model can enable the decorative cover 40 to move freely when the vehicle is in motion by arranging a power device 50 and a transmission device 60. When the vehicle brakes, the power device 50 pushes the transmission device 60 to rotate. During the rotation of the transmission device 60, it drives the decorative cover 40 to rotate relative to the wheel spoke 20, so that a gap is formed between the decorative cover 40 and the wheel spoke 20 to introduce air flow, thereby accelerating the air convection inside the rim 10, taking away the high temperature generated by the friction between the brake disc and the caliper, and ensuring the braking performance and driving experience of the vehicle. When the vehicle is driving normally, the power device 50 can push the transmission device 60 to rotate in the reverse direction. During the rotation of the transmission device 60, the decorative cover 40 is reset, and the wheel spoke 20 and the decorative cover 40 are basically in contact with each other, reducing the amount of air entering the rim 10 and reducing the wind resistance during driving, so as to achieve the purpose of reducing energy consumption.
