[0002] With the development of vehicle technology, smart antennas have gradually become an important component of vehicles. Since the signal strength, interference resistance, and other performance indicators of smart antennas are greatly affected by their placement location, the location of the antenna has a significant impact on its performance.

[0003] Currently, smart antennas are generally installed below the vehicle's dashboard or mounted on the roof in a shark fin configuration. However, when the smart antenna is installed below the dashboard, it is susceptible to interference from metal objects inside the vehicle, resulting in poor signal reception. When dealing with all-glass roofs, the antenna and roof rack are positioned on their respective mounting brackets, which are welded to the vehicle body. The gap between the roof rack and the antenna cover is long, and the positioning is affected by the vehicle body and the welding process. This makes existing smart antennas unable to meet the usage requirements of current vehicles. Utility Model Content

[0040] Please see Figure 2 and Figure 7 The antenna 3 has at least one positioning slot 302, and the housing 4 has at least one positioning element 402 inside. The number of positioning elements 402 is the same as the number of positioning slots 302, and the positioning elements 402 are fixedly installed in the corresponding positioning slots 302.

[0041] In one embodiment of this application, specifically, three positioning slots 302 are formed on the top surface of the antenna 3, and three positioning members 402 facing the antenna 3 are provided on the inner top surface of the housing 4. The three positioning slots 302 are respectively located on different axes in the length direction of the luggage rack 1 (the three positioning members 402 are spaced apart in the length direction of the luggage rack 1). The three positioning slots 302 are respectively located on both sides in the width direction of the luggage rack 1. The three positioning members 402 are correspondingly arranged with the three positioning slots 302. The three positioning members 402 are respectively set in the corresponding positioning slots 302 to limit and fix the housing 4.

When the extension part 4021 and the limiting part 4022 penetrate into the positioning groove 302, the upper part of the limiting part 4022 abuts against the second limiting step to limit the movement.

[0043] Please see Figure 3 and Figure 5 In one embodiment of this application, specifically, the protrusion of the housing 4 near the luggage rack 1 forms the docking portion 401. The length of the docking portion 401 is less than the length of the end face of the housing 4 near the luggage rack 1, and the width of the docking portion 401 is less than the width of the end face of the housing 4 near the luggage rack 1. A first limiting step is formed between the docking portion 401 and the housing 4. One end of the luggage rack 1 is recessed along the axial direction to form the mounting portion 101. The docking portion 401 is disposed in the mounting portion 101. The docking portion 401 is a rectangular column structure and extends into the mounting portion 101. The housing 4 limits the mounting portion 101. The docking portion 401 and the mounting portion 101 play a primary positioning role in the installation of the housing 4.

[0044] The bottom of the mounting part 101 is provided with a mounting groove 103, and the end face of the docking part 401 near the luggage rack 1 is provided with a protruding fourth positioning part 403.

[0045] In one embodiment of this application, specifically, the cross-sections of the mounting groove 103 and the fourth positioning part 403 along the length of the luggage rack 1 are both grid-shaped structures, and the fourth positioning part 403 is made of an elastic material.

[0046] Please see Figure 1 , Figure 3 and Figure 6 The end of the housing 4 away from the luggage rack 1 is gradually tilted toward the mounting base 2 to form a limiting surface.

[0047] In one embodiment of this application, specifically, the end of the housing 4 away from the luggage rack 1 is inclined in an arc shape toward the mounting base 2 to form a limiting surface. The interior of the housing 4 away from the luggage rack 1 has a reduced space for accommodating components in the direction away from the luggage rack 1. The arc-shaped inner wall of the housing 4 limits the antenna 3, and the antenna 3 also limits the housing 4.

[0048] The housing 4 is provided with a first limiting member 404 for limiting the antenna 3. The antenna 3 is provided with a limiting groove 303. The first limiting member 404 abuts against the inner wall of the limiting groove 303 in the direction away from the luggage rack 1.

The hypotenuse of the second limiting member 405 is in contact with the inner top surface of the housing 4, and the vertical side of the second limiting member 405 abuts against the third limiting step of the antenna 3, which is used to restrict the housing 4 from sliding away from the luggage rack 1.

[0052] In one embodiment of this application, specifically, both sides of the shell 4 in the length direction are inclined surfaces, and the inclined surfaces have the effect of guiding rainwater.

[0053] Please see Figure 7 In one embodiment of this application, the housing 4 specifically includes a first housing section 406 and a second housing section 407 fixedly connected along the direction from the luggage rack 1 to the housing 4. Each surface of the first housing section 406 is gradually inclined towards the axis of the first housing section along the direction from the housing 4 to the mounting bracket. The height and width of the second housing section 407 remain unchanged. The height and width of the first housing section 406 gradually increase along the direction away from the luggage rack 1 to ensure sufficient installation space for the antenna 3. At the same time, the first housing section 406 is small in size, saving materials and reducing its weight.

[0054] In one embodiment of this application, specifically, the mounting base 2 is provided with welding positions for installation and positioning, and multiple welding positions are provided for connection with the vehicle body.

[0055] This application also provides a vehicle including the antenna assembly described above.
