Description

Technical Field

[0001] The utility model belongs to the technical field of traffic equipment, and particularly relates to a mechanical automatic gearshift lever device, which is applicable to the operation scenario of a cargo robot. Background Art

[0002] The traditional gearshift lever devices in garages or intersections are usually made of metal or plastic materials, and are mainly designed to play a warning and slight blocking role. However, due to the limitations of their structural design and material selection, these gearshift levers often do not have sufficient strength and durability. During actual use, the gearshift lever may bend, break, or even completely fail due to accidental impact of a vehicle or driver's negligence, thus unable to effectively play the expected vehicle blocking role.

[0003] Currently, in an unmanned workshop, the traffic vehicles are mainly cargo robots. The structure of a cargo robot is generally a structure with a cargo platform and multiple walking wheels below, resulting in a very low height of the cargo robot. When the cargo robot is unloaded, the traditional gearshift lever cannot block it. When the cargo robot is loaded, the traditional gearshift lever will collide with the goods when blocking, and accidents are likely to occur. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a mechanical automatic gearshift lever device aiming at the deficiencies in the above-mentioned prior art. By controlling the rotation of an L-shaped gearshift lever through a driving unit, the wheels of a vehicle can be blocked, and a low-lying cargo robot can be effectively blocked.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a mechanical automatic gearshift lever device, comprising an outer frame main body, a driving unit, a control unit, an L-shaped gearshift lever, a first limit switch, a second limit switch, a first limit component, and a second limit component;

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

[0007] The L-shaped gearshift lever, the control unit, the first limit switch, the second limit switch, the first limit component, and the second limit component are all located inside the outer frame main body. The driving unit and the second limit component are both controlled by the control unit. The first limit switch and the second limit switch are both signal-connected to the control unit. The L-shaped gearshift lever comprises a first section and a second section that are perpendicular to each other;

[0008] The L-shaped car stopper is connected to the driving unit in a transmission manner. When the driving unit drives the L-shaped car stopper to rotate counterclockwise by 90°, the free end of the first segment of the L-shaped car stopper rotates from the inside of the outer frame body to the outside of the outer frame body, and the free end of the second segment of the L-shaped car stopper rotates from the first limit switch position to the second limit switch position. The first limit component limits the counterclockwise rotation direction of the L-shaped car stopper, and the second limit component limits the clockwise rotation direction of the L-shaped car stopper.

[0009] In the above-mentioned mechanical automatic car stopper device, a reinforcing diagonal brace is installed between the first section and the second section of the L-shaped car stopper.

[0010] The addition of the reinforced diagonal brace significantly improves the structural strength and durability of the car blocker. Compared with the car blocker made of traditional materials, the car blocker of the utility model is more resistant to accidental collisions and driver negligence, and reduces the risk of bending and breaking.

[0011] The above-mentioned mechanical automatic car stop rod device, the second limit assembly includes an electric push rod, a movable connecting piece, a guide rail and a slider; the movable connecting piece 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, the slider is installed on the guide rail, when the electric push rod is extended and retracted, the slider slides along the guide rail; the electric push rod is controlled by the control unit;

[0012] When the driving unit drives the L-shaped car stopper to rotate 90° counterclockwise, the electric push rod is extended to move the slider to the rear side of the second section of the L-shaped car stopper for limiting.

[0013] The electric push rod design of the second limiting assembly provides a flexible and precise limiting mechanism.

[0014] In the above-mentioned mechanical automatic car stop rod device, the second limiting assembly is arranged on the inner side of the L-shaped car stop rod, and a connecting limiting block is installed on the inner side of the second section of the L-shaped car stop rod. When the driving unit drives the L-shaped car stop rod to rotate counterclockwise by 90°, the electric push rod extends to move the slider to the rear side of the second section of the L-shaped car stop rod, and the slider and / or the movable connecting member are supported on the rear side of the connecting limiting block for limiting.

[0015] The second limiting component is arranged on the inner side of the L-shaped vehicle stopper and cooperates with the connecting limiting block to provide a more concealed and effective limiting method. Compared with the traditional vehicle stopper, the device of the utility model can better adapt to the low structure of the cargo robot and prevent accidents caused by improper limiting.

[0016] In the above-mentioned mechanical automatic vehicle stop lever device, a shift plate is installed at the free end of the second section of the L-shaped vehicle stop lever, and the shift plate is used to trigger the first limit switch and the second limit switch.

[0017] The shift lever is designed to trigger the limit switch. Compared with the traditional car blocking rod, the device of the utility model can provide more accurate feedback on the position of the car blocking rod, ensuring that the car blocking rod is blocked at the correct position, thereby improving the accuracy and safety of the operation.

[0018] In the above-mentioned mechanical automatic car stop lever device, the L-shaped car stop lever is transmission-connected to the driving unit via a rotating connecting piece.

[0019] The use of the rotating connecting piece allows a flexible transmission connection to be achieved between the car stopper rod and the drive unit. Compared with the traditional car stopper rod, the device of the utility model can reduce friction and wear during the transmission process, thereby improving the transmission efficiency and the service life of the car stopper rod.

[0020] The above-mentioned mechanical automatic vehicle stop lever device, the driving unit is a reduction motor.

[0021] By using a reduction motor as a driving unit, compared with the traditional car stopper, the device of the utility model can provide stable and adjustable rotational power. At the same time, the precise control ability of the reduction motor helps to achieve precise positioning of the car stopper, thereby improving the reliability of the car stopper.

[0022] In the above-mentioned mechanical automatic vehicle stop rod device, the second limiting component is a column structure.

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

[0024] Compared with the prior art, the utility model has the following advantages: the mechanical automatic car blocking rod device of the utility model provides a car blocking rod solution with simpler structure, more reliable structure and more comprehensive functions by integrating the control unit and the drive unit. Compared with the traditional car blocking rod with simple warning and slight blocking function, the device of the utility model can effectively block the low cargo robot by accurately controlling the position and angle of the car blocking rod, and can prevent accidents even in the empty or loaded state.

[0038] As Figure 1 —shown in FIG. 6, the mechanical automatic car stop bar device is applicable to unmanned workshops with a high degree of automation, especially those environments where low-load carrying robots are used for transportation operations.

[0039] I. Device structure:

[0040] Outer frame main body 1: It is made of strong metal materials, has sufficient strength and durability, and can withstand the collision of the carrying robot. In actual implementation, the outer frame main body 1 is horizontally installed on the ground.

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

[0042] Driving unit 9: It uses a reduction motor, and by precisely controlling the rotation speed and direction of the motor, the accurate rotation of the L-shaped car stop bar 2 is realized.

[0043] Control unit 10: It integrates a microcontroller and related circuits, is responsible for receiving external signals, and controls the actions of the driving unit 9 and the second limit component.

[0044] The first limit switch 6 and the second limit switch 7: They are respectively installed at predetermined positions inside the outer frame body 1 and are used to detect the rotation state of the L-shaped vehicle stop bar 2.

[0045] The first limit component 8 and the second limit component: The second limit component includes an electric push rod 3, a moving connecting piece 11, a guide rail 5 and a slider 4, which realizes precise limiting of the L-shaped vehicle stop bar 2 in the clockwise rotation direction. The first limit component 8 adopts a fixed structure to prevent the L-shaped vehicle stop bar 2 from rotating counterclockwise excessively.

[0046] Workflow:

[0047] Step 1, Initialization: After the control unit 10 receives the start signal, it 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, Detect the vehicle: It is detected by the sensor that the cargo robot approaches the position of the L-shaped vehicle stop bar 2.

[0049] Step 3, Deploy the vehicle stop bar: The control unit 10 sends a signal to the drive unit 9, the reduction motor starts, and drives the L-shaped vehicle stop bar 2 to rotate counterclockwise by 90° through the rotating connecting piece 2.3. The L-shaped vehicle stop bar 2 extends to the outside of the outer frame body 1 to prepare 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 vehicle stop bar reaches the predetermined position, and the first limit component 8 prevents excessive rotation; according to the signal of the control unit 10, the electric push rod 3 of the second limit component expands and contracts to make the slider 4 move along the guide rail 5 to the rear side of the second section of the L-shaped vehicle stop bar 2, and cooperate with the connecting limit block 2.2 on the L-shaped vehicle stop bar 2 to achieve precise limiting.

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

[0052] Step 6, Recover the vehicle stop bar: After the control unit 10 receives the release signal, the electric push rod 3 of the second limit component contracts to cancel the limit on the rear side of the second section of the vehicle stop bar. The drive unit 9 rotates the L-shaped vehicle stop bar 2 in the reverse direction. When the first limit switch 6 is triggered, it means that the second section of the L-shaped vehicle stop bar 2 reaches the predetermined position. The control unit 10 controls the drive unit 9 to stop rotating, and the L-shaped vehicle stop bar 2 returns to the original position to prepare for the next operation.

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

[0054] Compared with traditional barrier rods, the barrier rod device of this embodiment has higher structural strength and durability, can meet the usage requirements of low-loading robots in unmanned workshops, prevent safety accidents caused by impacts or negligence, and at the same time, through precise limit control, effectively avoid collisions with goods, improving the transportation efficiency and safety of the workshop.

Any simple modifications, changes, and equivalent structural changes made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
