[0025] What needs to be specifically explained in this embodiment is that the wheel hub heat dissipation device 1 is beneficial to improving the heat dissipation effect of the automobile wheel hub, reducing the probability of accidents caused by excessive hub temperature leading to increased automobile tire pressure, the shield fixing device 2 is beneficial to improving the stability of the automobile shield on the wheel hub, and preventing the automobile shield from falling off during vehicle driving, and the wear reduction device 3 is beneficial to reducing the wear of the shield caused by the rotation of the wheel hub during vehicle driving. The specific structure and working principle of the above components will be described in detail later.

[0026] In a preferred embodiment, the hub cooling device 1 includes an intermediate block 101, a fan blade 102 is welded in the middle of the side of the intermediate block 101, a connecting rod 103 is welded at the front end of the side of the intermediate block 101, a fan shell 104 is welded at one end of the connecting rod 103, a first connecting strip 105 is welded at the side of the fan shell 104, a hub protective cover 106 is welded at one end of the first connecting strip 105, and a sliding groove 107 is provided on the back of the hub protective cover 106.

[0027] What needs to be specifically explained in this embodiment is that a fan blade 102 is fixed in the middle of the wheel hub heat dissipation device 1. When the wheel hub heat dissipation device 1 rotates along with the rotation of the automobile hub, the fan blade 102 also rotates and produces an air-cooling heat dissipation effect, which is beneficial to improving the heat dissipation effect of the automobile hub and reducing the probability of accidents caused by excessive hub temperature leading to increased tire pressure.

[0028] In a preferred embodiment, the shield fixing device 2 includes a mounting device 201, and both ends of the bottom of the mounting device 201 are movably connected with second plungers 202, one end of each of the two second plungers 202 is welded with a second connecting strip 203, and one side of one end of each of the two second connecting strips 203 is welded with a movable rod 204, the back of the mounting device 201 is bolted to the first connecting strip 105, both sides of the first connecting strip 105 are welded with first fixing blocks 205, the backs of the two first fixing blocks 205 are welded with second fixing blocks 206, one side of the two second fixing blocks 206 is welded with a second spring 207, one end of each of the two second springs 207 is welded with a clip 208, the front end of one side of each of the two clips 208 is fixedly connected with a clamping block 209, and one end of the two movable rods 204 is welded with a clip 208.

[0029] In a preferred embodiment, the mounting device 201 includes a mounting plate 2011, the middle bolt on the front of the mounting plate 2011 is connected to the cylinder shell 2012, the first spring 2013 is welded on both sides of the cylinder shell 2012, the inner side of the cylinder shell 2012 is fixedly sleeved with a plunger cylinder 2014, one end of the two plunger cylinders 2014 is welded with a pressing block 2015, one end of the two first springs 2013 is welded with a pressing block 2015, the middle pipe at the bottom of the plunger cylinder 2014 is connected to the first air pipe 2016, and the bottom pipe of the first air pipe 2016 is connected to the second air pipe 2017.

[0030] What needs to be specifically explained in this embodiment is that an airflow is generated by the plunger cylinder 2014, and the airflow enters the second air pipe 2017, thereby increasing the pressure of the air pipe. The pressure pushes the second plungers 202 at both ends of the second air pipe 2017 outward, and one end of the second plunger 202 is fixedly connected to the clip 208. When the second plunger 202 moves, the clip 208 also moves. When the second plunger 202 drives the clip 208 to move to both sides, the space between the two clips 208 becomes larger. At this time, the wheel hub heat dissipation device 1 is placed on the wheel hub, and the pressing block 2015 is released. Under the action of the second spring 207, the clip 208 is reset and fixed to the wheel hub, which is beneficial to improve the stability of the car protective cover on the wheel hub and prevent the car protective cover from falling off during vehicle driving.

[0031] In a preferred embodiment, the wear reducing device 3 includes a rotating ring 301 , and a grinding plate 302 is fixedly connected to the back side of the rotating ring 301 .

[0032] What needs to be specifically explained in this embodiment is that a rotating ring 301 is added to the side of the hub heat dissipation device 1 facing the hub, so that the friction force when the hub rotates acts on the grinding plate 302. The friction force will cause the rotating ring to rotate, buffering the friction, which is beneficial to reducing the wear of the protective cover caused by the rotation of the hub when the car is driving.

[0033] The working principle of this utility model:

[0034] A fan blade 102 is fixed in the middle of the wheel hub heat dissipation device 1. When the wheel hub heat dissipation device 1 rotates along with the rotation of the automobile hub, the fan blade 102 also rotates and produces an air-cooling heat dissipation effect, which is beneficial to improving the heat dissipation effect of the automobile hub and reducing the probability of accidents caused by excessive hub temperature leading to increased tire pressure.

[0035] An air flow is generated by the plunger cylinder 2014, and the air flow enters the second air pipe 2017, increasing the pressure of the air pipe. The pressure pushes the second plungers 202 at both ends of the second air pipe 2017 outward. One end of the second plunger 202 is fixedly connected to the clip 208. When the second plunger 202 moves, the clip 208 also moves. When the second plunger 202 drives the clip 208 to move to both sides, the space between the two clips 208 becomes larger. At this time, the wheel hub heat dissipation device 1 is placed on the wheel hub, and the pressing block 2015 is released. Under the action of the second spring 207, the clip 208 is reset and fixed to the wheel hub, which is beneficial to improve the stability of the car shield on the wheel hub and prevent the car shield from falling off during vehicle driving.

[0036] A rotating ring 301 is added to the side of the hub heat sink 1 facing the hub, so that the friction force when the hub rotates acts on the grinding plate 302. The friction force will cause the rotating ring to rotate, buffering the friction, which is beneficial to reducing the wear of the protective cover caused by the rotation of the hub during driving of the car.
