Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for intelligent connected systems, specifically a communication antenna adjustment bracket for testing intelligent connected systems. Background Technology

[0002] As intelligent connected terminals, the testing of the vehicle communication system of new energy vehicles requires precise simulation of antenna attitude. In the research and development and testing phase of new energy vehicles, in order to verify the signal transmission and reception capabilities, positioning accuracy and data transmission stability of the vehicle communication module in different scenarios, the test antenna must be accurately and securely installed on the roof of the vehicle, and the real communication environment of the vehicle under dynamic and multi-attitude conditions must be simulated.

[0003] Existing new energy vehicles have extremely high requirements for lightweighting, low wind resistance, and overall vehicle aesthetics. Their roof structures are often smoother. Traditional antenna bracket fixing methods may not only damage the paint or disrupt aerodynamic design, but also fail to provide sufficient vibration resistance and stability under high-speed driving or complex road conditions, leading to slight antenna displacement or vibration. This seriously affects the accuracy of high-precision signal testing. Secondly, the intelligent connected vehicle testing scenarios for new energy vehicles are becoming increasingly complex. For example, it is necessary to simulate the antenna attitude of the vehicle under different suspension compression states, such as uphill and downhill, side tilt, or other conditions. This places stringent requirements on the adjustment range, accuracy, and stability of the antenna tilt angle. Existing bracket adjustment mechanisms often suffer from cumbersome operation, discontinuous adjustment, and easy loosening of positioning. They cannot meet the needs of testers for rapid, accurate, and repeatable adjustments to the antenna attitude, resulting in low testing efficiency and difficulty in ensuring the consistency and comparability of test data.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a communication antenna adjustment bracket for testing intelligent connected systems, comprising a base, a vacuum suction cup embedded and fixedly connected to the bottom of the base, a sealing ring fixedly connected to the bottom of the base and surrounding the outer side of the vacuum suction cup, an extension block fixedly connected to the front end of the base, and a rectangular hole laterally opened inside the extension block and extending through the extension block, a positioning mechanism fixedly connected inside the rectangular hole, and a set of left and right symmetrical connecting strips fixedly connected to the top end of the base, and a bracket installation and adjustment mechanism movably connected to the opposite side of the connecting strips.

[0007] Furthermore, the positioning mechanism includes a control motor, a winding roller, a cable, and a control block. The control motor is fixedly connected to the outside of the extension block. The winding roller is movably connected to the inside of the rectangular hole via a rotating shaft.

The slide bar is fixedly connected to the upper and lower sides of the control block, and the positioning bar is movably connected to the end of the control block away from the cable through a rotating shaft. The other end of the positioning bar is in the shape of a hook.

[0009] Furthermore, a set of symmetrical sliding grooves are provided at both ends of the interior of the rectangular hole, and the sliding grooves are adapted to the sliding strips, with the sliding strips slidably connected to the interior of the sliding grooves.

[0010] Furthermore, the bracket mounting and adjustment mechanism includes a drive motor, drive wheels, a drive belt, and drive shafts. There are two drive wheels connected by a drive belt. The output end of the drive motor is fixedly connected to the axis of one of the drive wheels.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-6 As shown, this utility model provides a technical solution: a communication antenna adjustment bracket for testing intelligent connected systems, including a base 1, a vacuum suction cup 2 embedded and fixedly connected to the bottom of the base 1, a sealing ring 3 fixedly connected to the bottom of the base 1, and the sealing ring 3 surrounding the outer side of the vacuum suction cup 2, an extension block 4 fixedly connected to the front end of the base 1, and a rectangular hole 5 laterally opened inside the extension block 4, and the rectangular hole 5 laterally penetrating the extension block 4, a positioning mechanism 6 fixedly connected inside the rectangular hole 5, and a set of left and right symmetrical connecting strips 7 fixedly connected to the top end of the base 1, and a bracket installation adjustment mechanism 8 movably connected to the opposite side of the connecting strips 7.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the positioning mechanism 6 includes a control motor 601, a winding roller 602, a cable 603, and a control block 604. The control motor 601 is fixedly connected to the outside of the extension block 4. The winding roller 602 is movably connected to the inside of the rectangular hole 5 via a rotating shaft. The output end of the control motor 601 passes through the extension block 4 and is fixedly connected to the axis of the winding roller 602. The two ends of the cable 603 are wound in opposite directions around the outside of the winding roller 602, and the control blocks 604 are respectively fixedly connected to the cable. At both ends of 603, the positioning mechanism 6 also includes a slide bar 605 and a positioning bar 606. The slide bar 605 is fixedly connected to the upper and lower sides of the control block 604 respectively. The positioning bar 606 is movably connected to the end of the control block 604 away from the cable 603 through a rotating shaft. The other end of the positioning bar 606 is in the shape of a hook. A set of symmetrical upper and lower sliding grooves 9 are opened at both ends of the rectangular hole 5. The sliding grooves 9 are adapted to the slide bar 605. The slide bar 605 is slidably connected to the inside of the sliding groove 9 respectively.

[0020] By controlling the motor 601 to drive the winding roller 602 to rotate, the two ends of the cable 603 wound on it synchronously retract inward, thereby driving the control block 604 fixed at the end of the cable 603 to slide smoothly along the slide groove 9. The control block 604 then pushes the hinged positioning strip 606 to tighten inward, so that the hook at the front end of the positioning strip 606 firmly hooks the longitudinal rail of the luggage rack, realizing the mechanical locking of the bracket. This effectively improves the stability and reliability of the bracket installed on the vehicle roof. At the same time, it is easy to operate, adapts to the luggage rack structure of different models, and enhances the versatility and practicality of the bracket.

[0021] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the bracket mounting and adjustment mechanism 8 includes a drive motor 801, drive wheels 802, a drive belt 803, and drive shafts 804. Two drive wheels 802 are provided and connected by the drive belt 803. The output end of the drive motor 801 is fixedly connected to the shaft center of one of the drive wheels 802. Two drive shafts 804 are provided, with one end of each fixedly connected to the shaft center of the drive wheel 802. The bracket mounting and adjustment mechanism 8 also includes an adjusting rod 805, a sliding ring 806, a collar 807, a sliding rod 808, a track groove 809, and a bracket base 810. The sliding ring 806 is fixedly connected to both ends of the adjusting rod 805, and the collar 807 is sleeved on the adjusting rod. At the middle position of 805, a set of left-right symmetrical track grooves 809 are fixedly connected to the bottom of the bracket 810. The two ends of the sliding rod 808 are slidably connected to the inside of the track grooves 809, and the middle position of the sliding rod 808 is fixedly connected to the top of the collar 807. Connecting grooves 10 are opened on opposite sides of the connecting bar 7, and the drive shafts 804 are movably connected to the inside of the connecting grooves 10 through bearings. The outer side of the drive shaft 804 is threaded, and the sliding rings 806 are movably connected to the drive shaft 804 through threads. The drive motor 801 is fixedly connected to the top of the extension block 4. The end of the bracket 810 away from the collar 807 is movably connected to the top of the connecting bar 7 through a rotating shaft.

[0022] Power is provided by the drive motor 801, which drives the two drive wheels 802 to rotate synchronously via the drive belt 803, ensuring that the two drive shafts 804 rotate at the same speed. The thread on the surface of the drive shaft 804 and the sliding ring 806 form a screw drive, which converts the rotational motion into the axial linear movement of the sliding ring 806. The sliding ring 806 then pushes the adjusting rod 805. The adjusting rod 805 drives the sliding rod 808 to slide in the preset track groove 809 through the collar 807, thereby lifting or lowering the rear end of the bracket 810, realizing continuous and stable adjustment of the tilt angle of the communication antenna.

[0023] Working principle: In use, first move the base 1 to the predetermined position on the top of the vehicle, then straighten the positioning strip 606 upwards. After the position is initially determined, control the vacuum suction cup 2 to adhere to the surface of the roof and ensure that the sealing ring 3 is tightly attached to the roof. Next, move the positioning strip 606 downwards so that its bottom hook-like structure is pre-attached to the longitudinal rails of the luggage rack on both sides of the vehicle roof. Start the control motor 601 to drive the winding roller 602 to rotate. The winding roller 602 winds and retracts the cable 603, and the two ends of the cable 603 retract into the rectangular hole 5. Under the tension of the cable 603, the control block 604 slides along the slide groove 9 into the rectangular hole 5 through the slide strips 605 on both sides, while simultaneously... The positioning bar 606 moves inward synchronously until the hook at the front end of the positioning bar 606 firmly hooks the longitudinal rail of the luggage rack, completing the overall fixation of the equipment. The communication antenna is then installed on the bracket 810. When the antenna tilt angle needs to be adjusted, the drive motor 801 is started, which drives the two drive wheels 802 to rotate synchronously through the drive belt 803, thereby driving the two drive shafts 804 to rotate. The thread on the surface of the drive shaft 804 drives the sliding ring 806 to move axially, which drives the adjusting rod 805 connected to it to move. The adjusting rod 805 pushes the collar 807 and the slide rod, causing the two ends of the slide rod to slide along the track groove 809, thereby lifting the rear end of the bracket 810, realizing continuous and stable adjustment of the communication antenna tilt angle.
