Description

Technical Field

[0001] This utility model relates to the field of vehicle barrier technology, and in particular to an angle-adjustable anti-collision garage barrier. Background Technology

[0002] With the increasing number of private cars in modern cities, the convenience and safety of parking garages have become a major concern. Novice drivers often struggle to accurately judge the vehicle's tilt angle when reversing into a parking space, frequently misjudging the situation and causing scrapes or failure to park, affecting efficiency and causing damage. Traditional garage door stoppers have several drawbacks. First, their function is extremely limited. Most are fixed structures that only rigidly restrict the vehicle's final parking position, failing to dynamically guide the vehicle's posture during reversing. Second, they lack impact-absorbing design. They are generally made of metal or hard plastic without any cushioning structure. When a collision occurs due to driver error, the impact force from the hard contact can damage the vehicle's bumper and chassis, and the door stop itself is prone to deformation and breakage due to the severe impact, resulting in high repair and replacement costs. Third, they lack feedback mechanisms. Even those equipped with reflective strips or warning lights only provide distance warnings and cannot offer intuitive references regarding the vehicle's tilt angle, completely failing to meet the core needs of novice drivers for reversing guidance and collision protection. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an angle-adjustable anti-collision garage barrier, which solves the technical problems of existing technologies being unable to dynamically guide the vehicle's posture during reversing and lacking a buffer anti-collision design.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an angle-adjustable anti-collision garage barrier, including a mounting plate, on both sides of the front of the mounting plate are symmetrically arranged anti-collision buffer mechanisms to mitigate the impact of reversing, a base is installed at the front end of the anti-collision buffer mechanism, a stop bar is provided on the base, a central gear is fixedly connected to the center of the top of the base, a meshing gear is meshed with the side of the central gear, a connecting shaft is installed on the top of the meshing gear, a motor for driving the connecting shaft to rotate is installed in the inner cavity of the stop bar, and a millimeter-wave radar and a camera are respectively installed on the top two sides of the stop bar.

[0005] A further improvement is that tempered glass covers are installed on the outside of both the millimeter-wave radar and the camera, reflective strips are installed on the front of the baffle, and light strips are symmetrically installed on both sides of the front of the baffle.

[0006] A further improvement is that a pressure sensor is mounted on the front array of the baffle, and a photoelectric alarm electrically connected to the pressure sensor is mounted on the side of the baffle.

[0007] A further improvement is that the anti-collision buffer mechanism includes a sleeve installed on the mounting plate, the sleeve is filled with hydraulic oil, and a sliding rod is slidably installed inside the sleeve. The front end of the sliding rod is connected to the base, and a piston adapted to the inner diameter of the sleeve is installed at the end of the sliding rod. A spring is installed between the piston and the inner wall of the sleeve, and damping holes are arrayed on the piston.

[0008] A further improvement is that the damping hole is a tapered hole that is narrow at the front and wide at the back, and a sealing ring is provided at the connection between the sleeve and the slide rod.

[0009] A further improvement is that an electrical contact is installed in the piston mounting groove, and an induction ring is installed in the middle of the sleeve, with the induction ring electrically connected to the photoelectric alarm.

[0010] A further improvement is that a central control element is installed inside the base, and all the aforementioned electrical components are electrically connected to the central control element.

[0011] By employing the above technical solution, this utility model provides an angle-adjustable anti-collision garage barrier, which has at least the following beneficial effects: 1. This utility model uses a camera to observe the car reversing into a parking space, and a millimeter-wave radar to scan the outline of the car body. At this time, the motor starts and drives the connecting shaft to rotate, which in turn drives the meshing gear to rotate around the central gear. The resulting reaction force drives the stop bar to rotate around the central axis of the central gear, so that the stop bar is always facing the car body. The driver can judge the tilt of the car body by observing the angle difference between the stop bar and the base through the rearview mirror, thereby assisting the driver to straighten the car body and complete the reversing into the parking space.

[0012] 2. According to the rotation angle of the baffle, the light strip lights up accordingly. The greater the deflection angle, the brighter the light and the red light is displayed, which makes it easier for the driver to understand the tilt angle of the vehicle body relative to the garage and helps the driver to straighten the vehicle body.

[0013] 3. When the tire collides with the stop bar, if it continues to move backward, the resulting impact force pushes the slide rod into the sleeve and drives the piston to squeeze the hydraulic oil. At this time, the hydraulic oil flows through the damping hole of the tapered structure that is narrow at the front and wide at the back. By utilizing Bernoulli's principle and the incompressibility of hydraulic oil, the impact force is buffered, thereby avoiding damage to the car body and stop bar caused by hard collision.

[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] Example 1 Addressing the limitations of current technologies in dynamically guiding vehicle posture during reversing and lacking buffering and collision-avoidance design, this embodiment provides an angle-adjustable anti-collision garage barrier. This barrier captures the vehicle's posture during reversing and drives the barrier bar to rotate synchronously. This allows the driver to judge the vehicle's tilt angle based on the barrier bar's rotation angle, assisting in reversing into the garage and buffering the impact force of the tires on the barrier bar, thus better protecting the vehicle. Please refer to... Figures 1-5This adjustable anti-collision garage barrier includes a mounting plate 1. Symmetrical anti-collision buffer mechanisms 2 are arranged on both sides of the front of the mounting plate 1 to mitigate the impact of reversing. A base 3 is mounted at the front end of the anti-collision buffer mechanism 2. A stop bar 4 is mounted on the base 3. A central gear 5 is fixedly connected to the center of the top of the base 3. A meshing gear 6 is meshed with the side of the central gear 5. A connecting shaft 7 is mounted on the top of the meshing gear 6. A motor 8, which drives the connecting shaft 7, is installed in the inner cavity of the stop bar 4. Millimeter-wave radar 9 and a camera 10 are respectively mounted on the top two sides of the stop bar 4. When the camera 10 detects a car reversing into the garage, the millimeter-wave radar 9 scans the car's outline. At this time, the motor 8 starts, driving the connecting shaft 7 to rotate, which in turn drives the meshing gear 6 to rotate around the central gear 5. The resulting reaction force causes the stop bar 4 to rotate around the central axis of the central gear 5, ensuring that the stop bar 4 is always directly facing the car body. The driver can judge the car's tilt by observing the angle difference between the stop bar 4 and the base 3 through the rearview mirror, thus assisting the driver in straightening the car and completing the reversing into the garage.

[0019] Furthermore, tempered glass covers 11 are installed on the outer sides of both the millimeter-wave radar 9 and the camera 10. The tempered glass covers 11 are installed to prevent damage to the millimeter-wave radar 9 and the camera 10 when the tires run over the guardrail 4. A reflective strip 12 is installed on the front of the guardrail 4. The reflective strip 12 can reflect the headlights and make it easier for the driver to observe the rotation angle of the guardrail 4 relative to the base 3, so as to judge the vehicle posture. Light strips 13 are symmetrically installed on both sides of the front of the guardrail 4. The rotation angle of the guardrail 4 is calculated by the encoder (not shown in the figure) installed on the motor 8. According to the rotation angle of the guardrail 4, the light strip 13 lights up accordingly (the larger the deflection angle, the brighter the light and the red light is displayed), so as to make it easier for the driver to understand the tilt angle of the vehicle body relative to the garage and assist the driver in straightening the vehicle body.

[0020] Traditional parking barriers rely solely on the vibrations generated by the vehicle body when the tire hits the barrier to determine whether the vehicle is parked correctly. For novice drivers, the feedback mechanism is not clear enough. Therefore, this device has pressure sensors 14 arrayed on the front of the barrier bar 4, and photoelectric alarms 15 electrically connected to the pressure sensors 14 are installed on the side of the barrier bar 4. When the tire hits the barrier bar 4, the tire squeezes the pressure sensors 14, at which point the photoelectric alarm 15 lights up and sounds an alarm, reminding the driver to complete the reverse parking and making it easier for the driver to judge the parking status.

[0021] The base 3 is equipped with a main control element 16. All the above-mentioned electrical components are electrically connected to the main control element 16, and the operation of each mechanism in the equipment is controlled by the main control element 16.

[0022] Example 2 Since most existing vehicle barriers use a fixed structure, when a vehicle collides due to operational error, the impact force generated by the hard contact can cause the barrier to deform or break. Therefore, based on Embodiment 1, as follows... Figures 1-5 As shown, the device is also equipped with an anti-collision buffer mechanism 2. The anti-collision buffer mechanism 2 includes a sleeve 21 installed on the mounting plate 1. The sleeve 21 is filled with hydraulic oil, and a slide rod 22 is slidably installed inside the sleeve 21. The front end of the slide rod 22 is connected to the base 3, and a piston 23 adapted to the inner diameter of the sleeve 21 is installed at the end of the slide rod 22. A spring 24 is installed between the piston 23 and the inner wall of the sleeve 21, and damping holes 25 are arrayed on the piston 23.

[0023] The damping hole 25 is a tapered hole that is narrow at the front and wide at the back. A sealing ring is provided at the connection between the sleeve 21 and the slide rod 22. When the tire collides with the retaining strip 4, if it continues to move backward, the impact force will push the slide rod 22 to slide into the sleeve 21 and drive the piston 23 to squeeze the hydraulic oil. At this time, the hydraulic oil flows in the tapered damping hole 25 that is narrow at the front and wide at the back. By utilizing Bernoulli's principle and the incompressibility of hydraulic oil, the impact force is buffered, thereby avoiding damage to the car body and retaining strip 4 caused by hard collision.

[0024] To further remind the driver of the progress of reversing into the parking space and prevent the vehicle from hitting the wall due to continuous backward movement, the device includes an electrical contact 26 installed in the mounting groove of piston 23 and an induction ring 27 installed in the middle of sleeve 21. The induction ring 27 is electrically connected to the photoelectric alarm 15. When piston 23 continues to move backward until the electrical contact 26 on piston 23 passes the induction ring 27, an electrical signal is sent to the photoelectric alarm 15, causing the photoelectric alarm 15 to emit an urgent alarm and a warning red light, reminding the driver to brake in time to avoid the vehicle hitting the wall and causing damage to both.
