Description

Technical Field

[0001] This utility model relates to the field of vehicle network communication testing technology, and in particular to an antenna bracket for whole-vehicle-level vehicle network MIMOOTA testing. Background Technology

[0002] With the rapid development of intelligent and connected vehicles, the communication needs between vehicles and the outside world are increasing. Vehicle-to-everything (V2X) networks not only need to achieve communication between vehicles and between vehicles and infrastructure, but also need to support information interaction between vehicles and pedestrians to provide a safer, more convenient, and intelligent driving experience. This makes the requirements for communication technology in V2X increasingly higher. Among them, the antenna is a key component of V2X communication, and its performance directly affects the communication quality and functional realization of V2X. In whole-vehicle-level V2X MIMO OTA testing, the antenna bracket is an indispensable auxiliary device. Its function is to accurately place the test antenna in a specific position to simulate real communication scenarios.

[0003] Existing antenna brackets for vehicle-level MIMO OTA testing suffer from limitations due to variations in vehicle height and structure across different models. Fixed-height brackets cannot flexibly adapt to the testing requirements of these different models, making it difficult to accurately simulate the actual communication environment during testing. This affects the accuracy and reliability of the test results. Therefore, we are introducing a new antenna bracket for vehicle-level MIMO OTA testing. Utility Model Content

[0004] The main objective of this invention is to provide an antenna bracket for vehicle-level MIMO OTA testing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An antenna bracket for vehicle-level MIMO OTA testing includes a fixed column, a connecting column fixedly connected to the upper middle part of the fixed column, a sliding groove formed on the front and rear parts of the outer surface of the connecting column, an inner groove formed inside the connecting column, an adjustment mechanism fixedly installed on the lower wall of the inner groove, a fixed block fixedly connected to the right part of the outer surface of the adjustment mechanism, an installation mechanism fixedly connected to the right end of the fixed block, an antenna body installed inside the installation mechanism, and a base fixedly connected to the lower end of the fixed column.

[0006] Preferably, the adjustment mechanism includes an electric telescopic rod, a top block is fixedly installed at the output end of the electric telescopic rod, an L-shaped fixing rod is fixedly connected to the lower left part of the top block, an adjustment cylinder is fixedly connected to the end of the L-shaped fixing rod away from the top block, and slide bars are fixedly connected to the front wall and the rear wall of the inner wall of the adjustment cylinder.

[0007] Preferably, the electric telescopic rod is fixedly installed on the lower wall of the inner groove, and the top block is located above the connecting column.

[0008] By adopting the above technical solution, the top of the block is designed with an arc surface, which can guide rainwater and prevent it from entering the inner groove and affecting the electric telescopic rod.

[0009] Preferably, the right side of the outer surface of the adjusting cylinder is fixedly connected to the fixing block, and the adjusting cylinder is located outside the connecting column, and the two slide bars are slidably connected to the two slide grooves respectively.

[0010] By adopting the above technical solution, the height of the adjusting cylinder can be adjusted by driving the electric telescopic rod, thereby enabling the antenna body to be adjusted in height.

[0011] Preferably, the mounting mechanism includes a mounting block, an extension rod is fixedly connected to the left side of the outer surface of the mounting block, a through slot is provided in the middle of the upper end of the mounting block, a locking screw is threadedly connected to the right side of the outer surface of the mounting block, and an anti-slip pad is fixedly connected to the end of the locking screw.

[0012] Preferably, the left end of the extension rod is fixedly connected to the fixing block, and the slot is inserted into the antenna body.

[0013] By adopting the above technical solution, the antenna body can be quickly inserted into the slot from the bottom of the mounting block, which facilitates the quick installation and replacement of the antenna body.

[0014] Preferably, the anti-slip pad is located inside the slot, and the end of the anti-slip pad away from the locking screw is in close contact with the antenna body.

[0015] By adopting the above technical solution, the anti-slip pad can increase the friction between the anti-slip pad and the antenna body, thus preventing the antenna body from slipping off.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up an installation mechanism, the antenna body is inserted into the slot from below the mounting block. By rotating the locking screw, the anti-slip pad is pressed and adhered to the antenna body, which can generate sufficient friction and pressure to fix the antenna body on the bracket. This facilitates the installation and replacement of the antenna body without complicated tools and cumbersome operating steps, saving installation time and labor costs and improving work efficiency. 2. By setting up an adjustment mechanism, the electric telescopic rod is activated, pushing the top block upwards. The top block, via the L-shaped fixing rod, moves the adjusting cylinder upwards, allowing the installed antenna body to be height-adjusted. This adjustable antenna bracket simulates different antenna height states in various real-world scenarios, making the test results closer to the vehicle's performance in real-world driving environments, thus improving the accuracy and reliability of the test. Furthermore, in whole-vehicle-level MIMO OTA testing, multiple tests may be required for different vehicle models, antenna configurations, and test items. The adjustable antenna bracket allows for quick antenna height adjustment, eliminating the need for reinstallation or replacement of the bracket each time, unlike fixed-height brackets, saving test preparation time and improving overall test efficiency.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: An antenna bracket for vehicle-level MIMO OTA testing includes a fixed column 1, a connecting column 2 fixedly connected to the upper middle part of the fixed column 1, a sliding groove 3 on the front and rear parts of the outer surface of the connecting column 2, an inner groove 4 inside the connecting column 2, an adjustment mechanism 5 fixedly installed on the lower wall of the inner groove 4, a fixed block 6 fixedly connected to the right side of the outer surface of the adjustment mechanism 5, an installation mechanism 7 fixedly connected to the right end of the fixed block 6, an antenna body 8 installed inside the installation mechanism 7, and a base 9 fixedly connected to the lower end of the fixed column 1.

[0023] In this embodiment, the adjustment mechanism 5 includes an electric telescopic rod 51. A top block 52 is fixedly installed at the output end of the electric telescopic rod 51. An L-shaped fixing rod 53 is fixedly connected to the lower left part of the top block 52. An adjustment cylinder 54 is fixedly connected to the end of the L-shaped fixing rod 53 away from the top block 52. Slide strips 55 are fixedly connected to the inner front wall and inner rear wall of the adjustment cylinder 54. The electric telescopic rod 51 is fixedly installed on the lower wall of the inner groove 4. The top block 52 is located above the connecting column 2. The right part of the outer surface of the adjustment cylinder 54 is fixedly connected to the fixing block 6, and the adjustment cylinder 54 is located outside the connecting column 2. The two slide strips 55 are slidably connected to the two sliding grooves 3 respectively.

[0024] The above scheme involves activating the electric telescopic rod 51, which pushes the top block 52 upward. The top block 52, via the L-shaped fixing rod 53, moves the adjusting cylinder 54 upward, thereby enabling the installed antenna body 8 to be height-adjusted.

[0025] In this embodiment, the mounting mechanism 7 includes a mounting block 71. An extension rod 72 is fixedly connected to the left side of the outer surface of the mounting block 71. A through slot 73 is opened in the middle of the upper end of the mounting block 71. A locking screw 74 is threadedly connected to the right side of the outer surface of the mounting block 71. An anti-slip pad 75 is fixedly connected to the end of the locking screw 74. The left end of the extension rod 72 is fixedly connected to the fixing block 6. The slot 73 is inserted and connected to the antenna body 8. The anti-slip pad 75 is located inside the slot 73, and the end of the anti-slip pad 75 away from the locking screw 74 is tightly fitted to the antenna body 8.

[0026] The above method involves inserting the antenna body 8 into the slot 73 from below the mounting block 71, and rotating the locking screw 74 to press and adhere the anti-slip pad 75 to the antenna body 8, generating sufficient friction and pressure to fix the antenna body 8 on the bracket, thus facilitating the installation and replacement of the antenna body 8.

[0027] It should be noted that this utility model is a MIMO (Multi-Input Multiple-Output) system for whole-vehicle networking. In the OTA testing antenna bracket, the antenna body 8 is inserted from the bottom of the mounting block 71 into the slot 73. Then, by rotating the locking screw 74, the anti-slip pad 75 applies pressure to the antenna body 8, ensuring a tight fit and sufficient friction to securely mount the antenna body 8 onto the bracket. This facilitates the installation and replacement of the antenna body 8, simplifies the operation process, eliminates the need for complex tools and lengthy steps, effectively shortens the installation cycle, reduces labor costs, and improves work efficiency. After the antenna body 8 is securely installed, the electric telescopic rod 51 is activated. The electric telescopic rod 51 then pushes the top block 52 upwards vertically. The top block 52 is simultaneously moved upwards via the L-shaped fixing rod 53 pulling the adjusting cylinder 54, thus achieving height adjustment of the installed antenna body 8. This height-adjustable antenna bracket design can simulate various antenna height states under different actual road conditions, making the test results closer to the vehicle's performance in real driving environments, thereby enhancing the accuracy and reliability of the test, especially in vehicle-level MIMO (Multi-mode Vehicle-to-Everything) testing. During OTA testing, adjustable antenna brackets demonstrate significant advantages in meeting the diverse needs of different vehicle models, antenna configurations, and test items: they can quickly adjust the antenna height, avoiding the inconvenience of fixed-height brackets needing to be reinstalled or replaced before each test, saving test preparation time, accelerating the overall testing process, and improving the overall efficiency of the testing work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
