Description

Technical Field

[0001] This utility model relates to the technical field of parking limit devices, specifically an adjustable-width roadside parking chassis limit device. Background Technology

[0002] With the continuous increase in the number of motor vehicles in cities, the demand for roadside parking is growing. Efficient and safe parking facilities have become the key to urban management. As a core device for regulating vehicle parking and ensuring parking order, roadside parking chassis limit devices can accurately limit the parking position of vehicles, prevent vehicle displacement or collision accidents, and improve the utilization rate of parking space. They are of great significance for alleviating urban parking pressure and optimizing the traffic environment.

[0003] Traditional roadside parking chassis limiting devices generally suffer from fixed structures and limited adjustment functions. Most devices have non-adjustable limiting dimensions, making it difficult to adapt to the chassis widths of different vehicle models. This results in large vehicles being unable to park or small vehicles lacking stability after parking. Although some devices have simple adjustment functions, the adjustment operation is cumbersome, relying on manual operation, which is inefficient and poses safety hazards. In addition, traditional devices often have defects in the side limiting design, failing to effectively prevent vehicles from drifting laterally, which can easily lead to scrape accidents. This not only increases the maintenance costs for car owners but may also cause traffic congestion, seriously affecting the efficiency and safety of urban parking management. To address these issues, we propose an adjustable-width roadside parking chassis limiting device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable-width roadside parking chassis limiting device, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an adjustable-width roadside parking chassis limiting device, including a base; The bottom of the inner wall of the base is provided with a transmission groove, and a fixing frame is fixedly connected to the bottom of the inner wall of the transmission groove; A stepper motor is fixedly connected to one end of the outer wall of the fixed frame, and the rotating shaft of the stepper motor extends to one end of the inner wall of the fixed frame. A lead screw is fixedly connected to the rotating shaft of the stepper motor. The end of the lead screw away from the stepper motor is movably connected to the bottom of the inner wall of the fixed frame via a connecting shaft. A slide rail is fixedly connected to the top of the inner wall of the fixed frame, and a limiting groove is opened on the top of the fixed frame, which is located above the slide rail; The bottom of the slide rail is slidably connected to a movable block, and the top of the movable block is movably sleeved on one end of the inner wall of the limiting groove. The bottom of the moving block is threadedly connected to the lead screw.

[0006] Preferably, movable arms are movably connected to both sides of the outer wall of the movable block, and an auxiliary arm is movably connected to the top of the fixed frame away from the limiting groove. The auxiliary arm is movably connected to the middle of both sides of the inner wall of the movable arm at the end away from the fixed frame.

[0007] Preferably, the end of the movable arm furthest from the moving block is movably connected to a top plate; The top of the top plate is equipped with a rubber pad.

[0008] Preferably, parallel limiting slide rods are fixedly connected to both ends of the inner wall of the base; The limiting slide bar is parallel to the horizontal plane; Sliding arms are respectively sleeved at both ends of the outer wall of the limiting slide rod.

[0009] Preferably, the inner wall of the base is provided with second transmission grooves that are equidistantly distributed on both sides, and a telescopic rod is fixedly connected to one side of the inner wall of the second transmission groove; The output end of the telescopic rod is fixedly connected to one side of the outer wall of the sliding arm, and the two sliding arms move in opposite directions.

[0010] Preferably, a limiting plate is fixedly connected to the top of the sliding arm.

[0011] Preferably, the outer walls at both ends of the base are provided with inclined plates.

[0012] Compared with the prior art, this utility model provides an adjustable width roadside parking chassis limiting device, which has the following beneficial effects: 1. This adjustable-width roadside parking chassis limiting device, compared to traditional limiting devices which are usually fixed in size or only allow for simple manual adjustment and are difficult to adapt to the chassis width of different vehicle models, resulting in large vehicles being unable to park or small vehicles being parked unstable, uses a stepper motor to drive a lead screw to rotate, causing the moving block to move precisely along the slide rail. This, in conjunction with the movable arm and the top plate, achieves automated and precise width adjustment. Whether it is a small car or a large SUV, the device's adjustment function can achieve precise positioning and stable support of the chassis, greatly improving the device's versatility and efficiency, and effectively solving the problems of narrow applicability and inconvenient adjustment of traditional devices.

[0013] 2. This adjustable-width roadside parking chassis limiting device, compared to traditional limiting devices that mostly only provide unidirectional limitation and cannot effectively prevent lateral displacement of vehicles during parking, easily leading to scratches and accidents, innovatively adopts a three-dimensional limiting structure combining a top plate and side limiting plates. The top plate is stably raised and lowered under the drive of the movable arm to achieve stable support for the vehicle chassis. At the same time, the telescopic rod drives the sliding arm to move the limiting plates in opposite directions, limiting the vehicle from the side. This three-dimensional limiting method restricts the parking position of the vehicle in all directions. Combined with the rubber pad on the top of the top plate to increase friction and the ramp design to reduce the resistance of vehicle entry, it significantly improves the safety of vehicle parking and reduces the risk of accidents caused by vehicle displacement. Compared with traditional devices, its safety performance is greatly improved.

[0014] 3. Compared to traditional devices, which often rely on manual adjustment, resulting in low efficiency and safety risks due to operational errors, and whose mechanical structures lack stability, making them prone to component loosening and transmission failure, this adjustable roadside parking chassis limiting device uses a stepper motor as its power source. This allows for precise control of the rotation angle and speed, enabling automated adjustment without manual intervention. This improves adjustment efficiency and avoids human error risks. Furthermore, the stable transmission system composed of components such as the fixed frame, slide rail, and limiting groove, combined with the triangular stability structure formed by the auxiliary arm and movable arm, ensures the stability and reliability of all components during operation, effectively preventing problems such as lead screw slippage and movable arm swaying. Compared to traditional devices, this device offers higher stability and reliability, reducing maintenance costs and failure rates. Attached Figure Description

[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] Please see Figure 1-4 An adjustable width roadside parking chassis limiting device includes a base 1. The base 1 serves as the basic load-bearing structure of the entire device, providing an installation platform and stable support for other components, ensuring that the device remains stable during use, and its function is to lay the foundation for the stable operation of the device. A transmission groove 2 is provided at the bottom of the inner wall of the base 1. A fixed frame 3 is fixedly connected to the bottom of the inner wall of the transmission groove 2. The fixed frame 3 is used to support and fix the core transmission components such as the stepper motor and the lead screw to ensure their stability and coaxiality during operation and prevent transmission failure due to component shaking. A stepper motor 4 is fixedly connected to one end of the outer wall of the fixed frame 3. The rotating shaft of the stepper motor 4 extends to one end of the inner wall of the fixed frame 3. A lead screw 5 is fixedly connected to the rotating shaft of the stepper motor 4. The lead screw 5 converts the rotational motion into linear motion under the drive of the stepper motor. Through the threaded engagement with the moving block, it realizes the precise control of the position of the moving block. Its function is to convert the rotational power into linear displacement. The lead screw 5 is connected to the bottom of the inner wall of the fixed frame 3 at the end away from the stepper motor 4. This ensures that the lead screw remains stable during rotation, avoids axial movement, ensures the accuracy and reliability of transmission, stabilizes the rotation of the lead screw, and prevents axial displacement. A slide rail 6 is fixedly connected to the top of the inner wall of the fixed frame 3. A limit groove 7 is opened on the top of the fixed frame 3. The limit groove 7 is located above the slide rail 6. The limit groove 7 restricts the movement range of the moving block to prevent it from falling off the slide rail during movement, while ensuring the accuracy of the movement trajectory of the moving block. Its function is to limit the movement range of the moving block and ensure the accuracy of the movement trajectory. The bottom of the slide rail 6 is slidably connected to a movable block 8. The top of the movable block 8 is movably sleeved on one end of the inner wall of the limiting groove 7. The movable block 8 moves linearly along the slide rail and the limiting groove under the drive of the lead screw. As a key component connecting the lead screw drive and the movable arm, it transmits the linear motion of the lead screw to the movable arm and drives the movable arm to move. The bottom of the moving block 8 is threadedly connected to the lead screw 5. Through threaded transmission, the precise displacement control of the moving block is achieved. The position of the moving block is precisely adjusted according to the number of rotations and direction of the stepper motor, thereby adjusting the width of the device. The effect is to achieve precise displacement adjustment of the moving block.

[0019] Movable arms 9 are movably connected to both sides of the outer wall of the movable block 8, and an auxiliary arm 10 is movably connected to the top of the fixed frame 3 away from the limit groove 7. The auxiliary arm 10 is movably connected at one end away from the fixed frame 3 to the middle of both sides of the inner wall of the movable arm 9, so that the auxiliary arm and the movable arm form a stable triangular structure, which enhances the rigidity and stability of the movable arm during the movement.

[0020] The movable arm 9 is movably connected to the top plate 11 at the end away from the movable block 8. The top plate 11 is lifted and moved laterally under the drive of the movable arm. It is used to lift the vehicle chassis and limit and support the vehicle. The rubber pad on the top increases the friction with the chassis to prevent the vehicle from sliding. Its function is to lift the vehicle chassis and achieve reliable limiting and support. The top of the top plate 11 is provided with a rubber pad 12. The rubber pad 12 increases the contact friction with the vehicle chassis and also plays a buffering role, protecting the vehicle chassis from scratches and improving the safety and reliability of the device. Its effect is to increase friction and protect the vehicle chassis.

[0021] The inner walls of the base 1 are fixedly connected with parallel limiting slide rods 13 at both ends. The limiting slide rods 13 provide guidance for the sliding arm, ensuring the linear movement of the sliding arm in the horizontal direction and preventing it from deviating or swaying. The limiting slide bar 13 is parallel to the horizontal plane; Sliding arms 14 are respectively sleeved at both ends of the outer wall of the limiting slide rod 13.

[0022] The base 1 has two equally spaced second transmission grooves 15 on both sides of its inner wall, and a telescopic rod 16 is fixedly connected to one side of the inner wall of the second transmission groove 15. The output end of the telescopic rod 16 is fixedly connected to one side of the outer wall of the sliding arm 14. The two sliding arms 14 move in opposite directions. The telescopic rod controls the opposite movement of the two sliding arms, thereby achieving synchronous limiting of the vehicle on both sides by the limiting plate, effectively preventing the vehicle from shifting laterally during parking.

[0023] The top of the sliding arm 14 is fixedly connected to a limiting plate 17. The limiting plate 17 cooperates with the top plate to limit the vehicle in three dimensions from both the side and the bottom, ensuring the stability and safety of the vehicle parking.

[0024] The outer walls at both ends of the base 1 are provided with ramps 18. The ramps 18 provide a transition slope for the vehicle entry device, reducing the difficulty and resistance when the vehicle enters, avoiding collision between the vehicle tires and the base, and improving the ease of use of the device and the safety of the vehicle.

[0025] Working Principle: First, the stepper motor 4, in conjunction with the lead screw 5 and the moving block 8, achieves the lateral displacement and width adjustment of the movable arm 9. The base 1 of the device has a transmission groove 2 at its bottom inner wall. The stepper motor 4, mounted on the fixed frame 3, has its rotation shaft connected to the lead screw 5. When the stepper motor 4 starts, the lead screw 5 rotates accordingly. Since the lead screw 5 is threadedly connected to the moving block 8, and the bottom of the moving block 8 slides in conjunction with the slide rail 6 (its top is movably fitted into the limiting groove 7), the rotation of the lead screw 5 is converted into linear motion of the moving block 8 on the slide rail 6. When the moving block 8 moves towards the stepper motor 4, it causes the movable arm 9 to unfold; conversely, when the moving block 8 moves away from the stepper motor 4, the movable arm 9 retracts inward, thereby changing the distance between the two movable arms 9 and realizing the height adjustment of the parking chassis limiting device to adapt to different vehicles. The movable arm 9, in conjunction with the top plate 11, achieves the effect of the top plate 11 moving up and down to lift the vehicle. One end of the movable arm 9 is hinged to the moving block 8, and the other end is hinged to the top plate 11. When the moving block 8 moves laterally under the drive of the lead screw 5, the movable arm 9 will swing around the hinge point with the moving block 8 as the fulcrum. As the movable arm 9 swings, the position of its hinge point with the top plate 11 changes, thereby driving the top plate 11 to move up and down in the vertical direction. When the vehicle drives into the appropriate position above the device, the stepper motor 4 drives the lead screw 5 to rotate, causing the moving block 8 to move. The movable arm 9 swings, thereby lifting the top plate 11 upward. The rubber pad 12 on the top of the top plate 11 contacts the vehicle chassis, steadily lifting the vehicle and achieving support and limiting of the vehicle chassis. Through the linkage of the base 1 and the ramp 18, the vehicle can easily drive in. The ramp 18 set on the outer walls of both ends of the base 1 has a reasonable inclination angle, which facilitates the smooth transition of the vehicle tires from the road surface to the top of the base 1. When a vehicle enters, the tires slide upwards along the ramp 18 until they reach a predetermined position above the top plate 11 at the corresponding position on the vehicle chassis. The presence of the ramp 18 reduces the resistance when the vehicle enters, preventing hard collisions between the tires and the edge of the base 1, thus improving the convenience and safety of the vehicle entry device. A stable guiding effect is achieved through the linkage of the limiting slide rod 13 and the sliding arm 14. The limiting slide rod 13 is fixed parallel to both ends of the inner wall of the base 1, and the sliding arm 14 is sleeved on its outer wall. When the telescopic rod 16 pushes the sliding arm 14 to move, the limiting slide rod 13 provides horizontal guidance for the sliding arm 14, ensuring that the sliding arm 14 can only move along the axis of the limiting slide rod 13, preventing swaying or deviation. This structure enhances the stability of the limiting plate 17 during movement, making the side limiting function more reliable and ensuring that the limiting plate 17 can accurately position the side of the vehicle.
