Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0041] As described in the background, in the existing two-wheeled vehicle, due to the small volume of the tire, the relative air leakage rate is also fast, the tire is easy to be out of air and the user cannot timely detect, causing problems such as low endurance, short tire life, poor user experience, etc. In addition, the tire pressure monitor is usually built-in in the tire, and the volume of the tire pressure monitor is large, and the small-diameter tire cannot provide enough installation space for the tire pressure monitor. And the fixing method of the tire pressure monitor is usually fixedly connected with the air valve, and the fixing stability still needs to be improved.

[0042] To solve the above technical problems, the wheel hub assembly provided in the first aspect of the present application comprises a wheel hub body and a tire pressure monitoring device. The wheel hub body has a boss. The tire pressure monitoring device is provided with a first through hole in a first direction, and the boss is arranged in the first through hole, so that the tire pressure monitoring device and the wheel hub body are fixedly connected.

By arranging the boss on the wheel hub body and the first through hole on the tire pressure monitoring device, the boss is arranged in the first through hole of the tire pressure monitoring device, so that the tire pressure monitoring device is fixed on the wheel hub body, thereby saving installation space and having high reliability and stability. The specific structure of the wheel hub assembly and the vehicle provided in the embodiments of the present application will be introduced below with reference to the drawings.

[0046] Reference Figure 1 In the first aspect, the present application provides a wheel hub assembly 100. The wheel hub assembly 100 can comprise a wheel hub body 200 and a tire pressure monitoring device 300.

The boss 210 can have any shape, which is not limited in the embodiments of the present application. In this way, the boss 210 can be inserted into the first through hole 310, so that the tire pressure monitoring device 300 is inserted into the boss 210, and the tire pressure monitoring device 300 and the hub body 200 are fixedly connected.

[0047] It should be noted that, for convenience of description, the first direction can be a thickness direction of the tire pressure monitoring device 300, such as an x direction in Figure 1

[0048] Referring to Figure 3 and Figure 4 , on the basis of the above embodiments, the hub body 200 can have a first recess 220 and a second recess 230 formed on an outer periphery of the hub body 200, and the tire pressure monitoring device 300 can be located in the second recess 230. In a possible implementation, the tire pressure monitoring device 300 can have a first surface 320 and a second surface 330, and the first surface 320 and the second surface 330 can be oppositely arranged. In the embodiments of the present application, the second surface 330 of the tire pressure monitoring device 300 can be attached to the second recess 230 of the hub body 200. In this way, the tire pressure monitoring device 300 can be attached to the second recess 230, and the stress of the tire during installation of the tire can be reduced.

[0049] It can be appreciated that, in the embodiments of the present application, the boss 210 on the hub body 200 can protrude from a plane in which the second recess 230 is formed. In other embodiments, the boss 210 on the hub body 200 can be located at any position on the plane in which the second recess 230 is formed, which is not limited in the embodiments of the present application.

[0050] Additionally, in the embodiments of the present application, the boss 210 on the hub body 200 can be formed by molding during the die casting of the hub body 200. Alternatively, the boss 210 on the hub body 200 can be formed by post-processing welding / bonding, which is not limited in the embodiments of the present application.

[0051] Continuing to refer to Figure 3 ​On the basis of the above-mentioned embodiments, in a possible implementation, the hub body 200 can further include a first hub side wall 240, a second hub side wall 250, and a connecting surface 260. In a possible implementation, the number of the first hub side wall 240, the second hub side wall 250, and the connecting surface 260 can be at least two, which is not limited in the embodiments of the present application. In the embodiments of the present application, the number of the first hub side wall 240, the second hub side wall 250, and the connecting surface 260 is taken as two for example.

The radial dimension of the second hole portion 350 can also be greater than or equal to the radial dimension of the third hole portion 360, so that the second step portion 380 is formed between the second hole portion 350 and the third hole portion 360. In this way, the fastener 400 can be sequentially inserted into the first hole portion 340, the third hole portion 360 and the second hole portion 350, and then engaged with the tire pressure monitoring device 300.
