[0039] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0040] The present invention provides a wheel hub logo orientation device, which includes:

[0041] The center position of one side of the shell can be rotatably connected to the center position of the wheel hub, and the other side of the shell is used to fix the car logo;

[0042] An eccentric counterweight block is connected to the shell;

[0043] The angular momentum generating assembly is arranged inside the shell and can generate angular momentum, and the angular momentum can overcome the rotation tendency of the shell relative to the wheel hub.

[0044] The angular momentum generating assembly includes at least one rotating body;

[0045] A cavity is provided in the shell, and at least one rotating body is provided in the cavity;

[0046] The same number of air flow channels as the number of the rotating body is provided between the two sides of the shell. The air flow can flow through the cavity through the air flow channels and drive the rotating body to rotate, so that the rotating body generates angular momentum that overcomes the rotation trend of the shell.

[0047] Specifically, the housing is circular. When the vehicle speed is zero or low, the eccentric counterweight can cause the housing to rotate through the action of gravity, so that the position of the eccentric counterweight remains at the lowest position. Furthermore, the vehicle logo on the housing does not rotate with the rotation of the wheel hub during display. The vehicle brand can be easily identified by the logo on the wheel hub, thereby enhancing the vehicle's sense of luxury.

[0048] When the speed of the car gradually increases, the gravity of the eccentric counterweight alone cannot keep the car logo from rotating as the wheel hub rotates. Therefore, the device sets at least one rotating body in the cavity of the shell, and sets air flow channels of the same number as the rotating bodies on its edge wall. The air flow flowing in from the air flow channel will blow the rotating body to rotate. When the speed of the car increases, the flow rate and flow of the air flow through the air flow channel increase, and the rotation speed of the rotating body increases. Therefore, the angular momentum of the rotating body increases, and the direction of the angular momentum is vertically upward and vertically downward. The vertical upward or vertical downward angular momentum of the rotating body is consistent with the direction of the gravity of the eccentric counterweight. When the speed is high, both can overcome the friction at the rotation position between the shell and the wheel hub, that is, overcome the rotation tendency of the shell relative to the wheel hub, to avoid a large difference in rotation speed between the wheel hub and the shell when the speed is high, which increases the friction at the rotation position of the shell and causes the shell to rotate.

[0049] When the car is not moving or is traveling at a low speed, the gravity of the eccentric counterweight is the main reason for keeping the shell from rotating with the rotation of the wheel hub. When the car is traveling at a high speed, the angular momentum of the rotating body is the main reason for keeping the shell from rotating with the rotation of the wheel hub. When the speed changes from low speed to high speed, the proportion of the two factors in keeping the shell from rotating with the rotation of the wheel hub gradually switches, and during the switching process, the shell does not rotate significantly.

[0050] When the car is undergoing rapid acceleration and deceleration, the angular momentum of the rotating body can also reduce the swing of the shell caused by the eccentric counterweight.

[0051] Preferably, the rotating body is an impeller.

[0052] Specifically, the existing impeller structure is easier to rotate during the airflow blowing process.

[0053] Preferably, the air flow channel comprises:

[0054] An air intake passage is provided on the edge wall of the shell body near the front of the vehicle body;

[0055] An air outlet channel is provided on the edge wall of the shell near the rear of the vehicle body;

[0056] The rotating body is arranged at a position between one end of the air inlet passage located in the shell and one end of the air outlet passage located in the shell.

[0057] Specifically, when the speed of the car gradually increases, the airflow flows into the shell from the air inlet channel and then flows out from the air outlet channel, blowing the rotating body inside the shell to rotate. The greater the speed of the car, the greater the flow rate and flow of the airflow flowing through the shell, the greater the speed of the rotating body, and therefore the greater the angular momentum of the rotating body.

[0058] Preferably, the angular momentum generating assembly further comprises:

[0059] A first support rod, one end of which is fixed to the center of a side surface inside the housing;

[0060] A second support rod, wherein the center position of the side wall of the second support rod is fixed to the other end of the first support rod, and one end of the second support rod faces the counterweight block;

[0061] There are two rotating bodies, and the two rotating bodies are respectively rotatably connected to the two ends of the second support rod.

[0062] Specifically, the first support rod and the second support rod cooperate to arrange the two rotating bodies symmetrically relative to the rotation center of the cavity.

[0063] Preferably, the number of the air flow channels is two, and each rotating body is arranged between an air inlet channel and an air outlet channel.

[0064] Specifically, the airflow flowing through the two airflow channels drives the two rotating bodies to rotate in the same direction.

[0065] Preferably, it further comprises an inner ring body and an outer ring body, wherein the inner ring body is rotatably connected to the outer ring body, one end of the inner ring body is fixed to the center position of one side surface of the shell, and the outer ring body is embedded in the center position of the hub;

[0066] A plurality of rolling elements are arranged between the inner ring body and the outer ring body.

[0067] Specifically, in order to adapt to the high speed working condition of the hub, the rolling body is preferably a spherical rolling body. The inner ring body and the outer ring body can rotate relative to each other through multiple rolling bodies. When one end of the inner ring body is fixed to the center position of one side of the shell, the outer ring body is embedded in the installation position of the hub.

[0068] Preferably, the air inlet passage is trumpet-shaped.

[0069] Specifically, the trumpet-shaped air intake passage can gather more air into a high-speed airflow through the cavity.

[0070] Preferably, the cross section of the eccentric counterweight is in the shape of an isosceles triangle, the two bottom corners of the counterweight are fixed to the inner edge wall of the shell, and the top corner of the counterweight points to the rotation center of the shell.

[0071] Specifically, it is easier to align the fixed vehicle logo and prevent the fixed vehicle logo from deflecting.

[0072] A car includes a wheel hub logo orientation device.

[0073] Example

[0074] The present invention provides a wheel hub logo orientation device, which includes:

[0075] The center of one side of the housing 6 can be rotatably connected to the center of the wheel hub, and the other side of the housing 6 is used to fix the vehicle logo;

[0076] The eccentric counterweight 4 is connected to the housing 6;

[0077] The angular momentum generating assembly is arranged inside the shell and can generate angular momentum, and the angular momentum can overcome the rotation tendency of the shell relative to the wheel hub.

[0078] In this embodiment, a cavity is provided in the shell, and at least one rotating body is provided in the cavity. Air flow channels with the same number as the rotating bodies are provided between the two sides of the shell. The air flow can flow through the cavity through the air flow channels and drive the rotating body to rotate, so that the rotating body generates angular momentum to overcome the rotation trend of the shell.

[0079] In this embodiment, the rotating body 5 is an impeller.

[0080] In this embodiment, the air flow channel includes:

[0081] The air intake channel 8 is provided on the edge wall of the shell 6 near the front of the vehicle body;

[0082] The air outlet channel 9 is provided at the edge wall of the housing 6 near the rear of the vehicle body;

[0083] The rotating body 5 is disposed between one end of the air inlet passage 8 located in the housing 6 and one end of the air outlet passage 9 located in the housing 6 .

[0084] In this embodiment, it also includes:

[0085] A first support rod, one end of which is fixed to the center of a side surface inside the housing 6;

[0086] A second support rod, the center of the side wall of the second support rod is fixed to the other end of the first support rod, and one end of the second support rod faces the counterweight 4;

[0087] There are two rotating bodies 5 , and the two rotating bodies 5 are respectively rotatably connected to the two ends of the second support rod.

[0088] In this embodiment, the number of air flow channels is two, and each rotating body is disposed between an air inlet channel and an air outlet channel.

[0089] In this embodiment, it also includes an inner ring body and an outer ring body. The inner ring body is rotatably connected to the outer ring body. One end of the inner ring body is fixed to the center position of one side surface of the shell, and the outer ring body is embedded in the center position of the hub.

[0090] In this embodiment, a plurality of rolling elements are provided between the inner ring body and the outer ring body.

[0091] In this embodiment, the air intake passage 8 is trumpet-shaped.

[0092] In this embodiment, the cross section of the eccentric counterweight is an isosceles triangle, the two bottom corners of the counterweight are fixed to the inner edge wall of the shell, and the top corner of the counterweight points to the rotation center of the shell.

[0093] A car includes a wheel hub logo orientation device.

[0094] In summary, when the wheel hub logo orientation device provided by the present invention is used, when the vehicle speed is zero or low, the eccentric counterweight 4 can cause the housing 6 to rotate due to the action of gravity, so that the position of the eccentric counterweight 4 is maintained at the lowest position. Furthermore, the logo on the housing 6 will not rotate with the rotation of the wheel hub during display, making it easy to identify the brand of the vehicle through the logo on the wheel hub, thereby enhancing the sense of luxury of the vehicle.

[0095] When the speed of the car gradually increases, the gravity of the eccentric counterweight 4 alone cannot keep the car logo from rotating with the rotation of the wheel hub. Therefore, the device sets at least one impeller in the cavity 7 of the shell 6, and sets an air inlet channel 8 and an air outlet channel 9 on its edge wall with the same number as the impeller. The air flow flows from the air inlet channel 8 into the shell 6 and flows out from the air outlet channel 9, blowing the impeller in the cavity 7 to rotate. When the speed of the car is higher, the air flow rate and flow rate flowing through the cavity 7 are higher, and the speed of the impeller is higher, so the impeller The greater the angular momentum of the wheel, the more the direction of the angular momentum is vertically upward and vertically downward. The vertically upward or vertically downward angular momentum of the impeller is consistent with the direction of gravity of the eccentric counterweight. When the vehicle speed is high, both can overcome the rotation of the inner ring body 3 caused by the friction force on the inner ring body 3, that is, overcome the rotation trend of the inner ring body 3 relative to the outer ring body 1, and avoid the situation when the vehicle speed is high. The rotation speed difference between the inner ring body 3 and the outer ring body 1 is large, which increases the friction force on the rotating position of the inner ring body 3 and causes the shell 6 to rotate.

[0096] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
