Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, and in particular relates to a mechanical automatic vehicle stop device, which is suitable for cargo robot operation scenarios. Background Technology

[0002] Traditional parking barriers in garages or drop-off shops are typically made of metal or plastic and are designed primarily to serve as warnings and provide a slight barrier. However, due to limitations in their structural design and material selection, these barriers often lack sufficient strength and durability. In actual use, they may bend, break, or even fail completely due to accidental vehicle impacts or driver negligence, thus failing to effectively stop vehicles as intended.

[0003] Currently, in unmanned workshops, the main vehicles are cargo robots. The structure of cargo robots is generally a cargo platform with multiple wheels underneath, which results in a very low height for cargo robots. When the cargo robot is empty, traditional barriers cannot stop it. When the cargo robot is loaded, the traditional barriers will collide with the cargo when they try to stop it, which can easily lead to accidents. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mechanical automatic vehicle stop device that addresses the shortcomings of the prior art. The L-shaped vehicle stop is controlled by a drive unit to rotate, thereby blocking the wheels of vehicles and effectively blocking low-profile cargo robots.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a mechanical automatic barrier device, comprising an outer frame body, a drive unit, a control unit, an L-shaped barrier, a first limit switch, a second limit switch, a first limit component, and a second limit component;

[0006] The L-shaped wheel stop is used to block the wheels of a vehicle;

[0007] The L-shaped barrier, control unit, first limit switch, second limit switch, first limit assembly, and second limit assembly are all located inside the outer frame body. The drive unit and second limit assembly are both controlled by the control unit. The first limit switch and second limit switch are both signal connected to the control unit. The L-shaped barrier includes a first segment and a second segment that are perpendicular to each other.

[0008] The L-shaped barrier and the drive unit are connected by a transmission. When the drive unit drives the L-shaped barrier to rotate counterclockwise by 90°, the free end of the first segment of the L-shaped barrier rotates from inside the outer frame to outside the outer frame, and the free end of the second segment rotates from the position of the first limit switch to the position of the second limit switch. The first limit component limits the counterclockwise rotation of the L-shaped barrier, and the second limit component limits the clockwise rotation of the L-shaped barrier.

[0009] In the aforementioned mechanical automatic barrier device, a reinforcing diagonal brace is installed between the first and second sections of the L-shaped barrier.

[0010] The addition of reinforced diagonal braces significantly improves the structural strength and durability of the parking barrier. Compared with parking barriers made of traditional materials, the parking barrier of this invention is more resistant to accidental impacts and driver negligence, reducing the risk of bending and breakage.

[0011] The aforementioned mechanical automatic barrier device includes a second limiting component comprising an electric push rod, a movable connector, a guide rail, and a slider. The movable connector is installed between the slider and the telescopic end of the electric push rod. The guide rail is arranged on the outer frame body along the telescopic direction of the electric push rod. The electric push rod is installed on the outer frame body, and the slider is installed on the guide rail. When the electric push rod telescopically extends or retracts, the slider slides along the guide rail. The electric push rod is controlled by a control unit.

[0012] When the drive unit drives the L-shaped barrier to rotate 90° counterclockwise, the electric push rod extends, causing the slider to move to the rear side of the second section of the L-shaped barrier for limiting.

[0013] The electric actuator design of the second limiting component provides a flexible and precise limiting mechanism.

[0014] In the aforementioned mechanical automatic barrier device, the second limiting component is located on the inner side of the L-shaped barrier. A connecting limiting block is installed on the inner side of the second segment of the L-shaped barrier. When the drive unit drives the L-shaped barrier to rotate counterclockwise by 90°, the electric push rod extends, causing the slider to move to the rear side of the second segment of the L-shaped barrier. The slider and / or the movable connecting piece support the rear side of the connecting limiting block for limiting.

[0015] By placing the second limiting component inside the L-shaped barrier and cooperating with the connecting limiting block, a more concealed and effective limiting method is provided. Compared with the traditional barrier, the device of the present invention can better adapt to the low structure of the cargo robot and prevent accidents caused by improper limiting.

[0016] The aforementioned mechanical automatic vehicle stop device has a shift plate installed at the free end of the second segment of the L-shaped vehicle stop, which is used to trigger the first limit switch and the second limit switch.

[0017] The toggle switch is designed to trigger the limit switch. Compared with the traditional barrier lever, the device of the present invention can provide more accurate barrier lever position feedback, ensuring that the barrier lever blocks in the correct position, thereby improving the accuracy and safety of operation.

[0018] In the aforementioned mechanical automatic barrier device, the L-shaped barrier is connected to the drive unit via a rotating connector.

[0019] The use of a rotating connector allows for a flexible transmission connection between the barrier and the drive unit. Compared with traditional barrier, the device of this invention can reduce friction and wear during transmission, thereby improving transmission efficiency and the service life of the barrier.

[0020] In the aforementioned mechanical automatic barrier device, the drive unit is a geared motor.

[0021] Using a geared motor as the drive unit, the device of the present invention can provide stable and adjustable rotational power compared with traditional parking barriers. At the same time, the precise control capability of the geared motor helps to achieve accurate positioning of the parking barrier, thus improving the reliability of the parking barrier.

[0022] In the aforementioned mechanical automatic vehicle stop device, the second limiting component is a column structure.

[0023] The columnar structure design of the second limiting component may provide better mechanical properties and a simplified manufacturing process, increasing the durability and cost-effectiveness of the limiting component.

[0024] Compared with existing technologies, this invention has the following advantages: The mechanical automatic barrier device of this invention, by integrating a control unit and a drive unit, provides a barrier solution with a simpler and more reliable structure and more comprehensive functions. Compared with traditional barrier devices that provide simple warnings and slight obstruction, the device of this invention can effectively block low-profile cargo robots by precisely controlling the position and angle of the barrier, preventing accidents even when the robot is empty or loaded.

[0038] like Figure 1 As shown in Figure 6, the mechanical automatic vehicle stop device is suitable for highly automated unmanned workshops, especially those environments where low-profile cargo robots are used for transportation operations.

[0039] I. Device Structure:

[0040] Outer frame 1: Made of sturdy metal material, it has sufficient strength and durability to withstand collisions with the cargo robot. In actual implementation, outer frame 1 is installed horizontally on the ground.

[0041] L-shaped parking barrier 2: includes a first section and a second section, made of high-strength plastic or metal alloy. The second section is vertically connected to the first section. The L-shaped parking barrier 2 is horizontally arranged as a whole. A reinforcing diagonal brace is set between the first section and the second section to enhance the stability of the overall structure.

[0042] Drive unit 9: It adopts a geared motor, and achieves accurate rotation of L-shaped stop lever 2 by precisely controlling the speed and direction of the motor.

[0043] Control unit 10: integrates a microcontroller and related circuits, and is responsible for receiving external signals and controlling the operation of drive unit 9 and second limit component.

[0044] First limit switch 6 and second limit switch 7: respectively installed in predetermined positions inside the outer frame body 1, used to detect the rotation state of L-shaped stop bar 2.

[0045] First limiting component 8 and second limiting component: The second limiting component includes an electric push rod 3, a movable connector 11, a guide rail 5, and a slider 4, which accurately limits the clockwise rotation of the L-shaped parking barrier 2. The first limiting component 8 adopts a fixed structure to prevent the L-shaped parking barrier 2 from rotating excessively counterclockwise.

[0046] Workflow:

[0047] Step 1, Initialization: After receiving the start signal, the control unit 10 initializes all components, including the drive unit 9, the first limit switch 6, the second limit switch 7, and the electric push rod 3.

[0048] Step 2, Vehicle Detection: Sensors detect the position of the cargo robot approaching the L-shaped barrier 2.

[0049] Step 3, Deployment of the barrier: The control unit 10 sends a signal to the drive unit 9, the reduction motor starts, and drives the L-shaped barrier 2 to rotate counterclockwise by 90° through the rotating connector 2.3. The L-shaped barrier 2 extends to the outside of the outer frame body 1 to block the wheels of the target cargo robot.

[0050] Step 4, Limiting Operation: The second limit switch 7 detects that the second section of the barrier arm has reached the predetermined position, and the first limit component 8 prevents excessive rotation; according to the signal from the control unit 10, the electric push rod 3 of the second limit component extends and retracts, causing the slider 4 to move along the guide rail 5 to the rear side of the second section of the L-shaped barrier arm 2, and cooperates with the connecting limit block 2.2 on the L-shaped barrier arm 2 to achieve precise limiting.

[0051] Step 5, Vehicle blocking: The free end of the first section of the L-shaped vehicle blocking bar 2 extends out to effectively block the cargo robot and prevent it from accidentally entering the prohibited area.

[0052] Step 6, Barrier Retraction: After receiving the release signal, the control unit 10 retracts the electric push rod 3 of the second limit assembly, canceling the limit on the rear side of the second section of the barrier. The drive unit 9 rotates the L-shaped barrier 2 in the opposite direction. When the first limit switch 6 is triggered, it indicates that the second section of the L-shaped barrier 2 has reached the predetermined position. The control unit 10 controls the drive unit 9 to stop rotating, and the L-shaped barrier 2 returns to its original position, ready for the next operation.

[0053] A shift plate 2.1 is installed at the free end of the second section of the L-shaped barrier 2. When the L-shaped barrier 2 reaches the limit position, the shift plate 2.1 triggers the limit switch to ensure that the barrier will not rotate excessively, and at the same time provides a feedback signal to the control unit 10.

[0054] Compared to traditional wheel stops, the wheel stop device in this embodiment has higher structural strength and durability, which can meet the usage requirements of low-profile cargo robots in unmanned workshops, prevent safety accidents caused by collisions or negligence, and effectively avoid collisions with goods through precise limit control, thereby improving the transportation efficiency and safety of the workshop.

[0055] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
