[0032] Figure 1 This is a structural schematic diagram of the three-dimensional parking garage of this utility model. Figure 2 This is a schematic diagram of the transverse movement mechanism of this utility model.
[0033] See Figure 1 This application provides a multi-level parking garage, which may include a parking space rack 100 and a lateral movement mechanism 200. The parking space rack 100 is provided with parking spaces for parking. The lateral movement mechanism 200 is used to carry vehicles to move vehicles into and out of the parking space rack 100.
[0034] In some embodiments, multiple parking spaces are provided, including a first parking space and multiple second parking spaces. Multiple second parking spaces are spaced horizontally and vertically to accommodate multiple vehicles. A lateral sliding structure carries the vehicle and moves it from outside the parking space frame 100 to the first parking space inside the parking space frame 100. Then, driven by a horizontal or vertical sliding structure in the automated parking system, the lateral sliding structure moves from the first parking space to the second parking space.
[0035] In some embodiments, multiple parking spaces are provided, including multiple first parking spaces and multiple second parking spaces. A lateral movement mechanism 200 is provided, capable of moving to different first parking spaces and then to different second parking spaces.
[0036] In some embodiments, multiple parking spaces are provided, including multiple first parking spaces and multiple second parking spaces. Multiple lateral movement mechanisms 200 are provided, each corresponding to one of the multiple first parking spaces, with each first parking space corresponding to one lateral movement mechanism 200.
[0037] See again Figure 1 and Figure 2 The automated parking system also includes a lateral sliding track 300, which extends along a first direction. One end of the lateral sliding track 300 extends into the parking space, and the other end extends out of the parking space. A lateral sliding mechanism 200 is movably mounted on the lateral sliding track 300 along the first direction, allowing the lateral sliding mechanism 200 to move between the parking space and the loading / unloading space. The loading / unloading space is located outside the parking space frame 100, and the vehicle moves from the loading / unloading space outside the frame onto the lateral sliding track 300. The lateral sliding mechanism 200 moves from the loading / unloading space along the first direction to the parking space, thereby transporting the vehicle into the parking space within the parking space frame 100.
[0038] In some implementations, the lateral transfer mechanism 200 moves from the upper parking space to the first parking space, transporting the vehicle on the lateral transfer mechanism 200 from the upper parking space to the first parking space.
[0039] In other embodiments, the traverse mechanism 200 moves from the upper parking space to the first parking space, transporting the vehicle on the traverse mechanism 200 from the upper parking space to the first parking space. Then, the traverse mechanism 200 is transported from the first parking space to the second parking space.
[0040] When retrieving a vehicle from a multi-level parking garage, the lateral movement mechanism 200 moves from the parking space to the upper parking space, transports the vehicle to the upper parking space, and then moves the vehicle out from the upper parking space.
[0041] In some embodiments, the distance between the parking space and the entry space is D, and the distance between the parking space and the entry space is recorded in the controller 500 of the automated parking garage.
[0042] In one embodiment, a parking space is provided with a first positioning point, and a loading space is provided with a second positioning point; the distance between the first positioning point and the second positioning point is D, which is set as the distance between the parking space and the loading space.
[0043] Figure 3 This is a side view of the transverse movement mechanism of this utility model.
[0044] See Figures 1 to 3The traverse mechanism 200 includes a vehicle carrier 210 and drive wheels 220. The drive wheels 220 are rotatably connected to the vehicle carrier 210 about their own axis. The drive wheels 220 are supported on a traverse track 300 and can roll along the traverse track 300 in a first direction, allowing the vehicle carrier 210 to move between parking spaces and loading / unloading spaces. The vehicle carrier 210 is used to carry and transport vehicles. The vehicle carrier 210 moves from the loading / unloading space to the parking space within the parking rack 100 to transport the vehicle for storage.
[0045] The drive wheel 220 is rotatably connected to the vehicle platform 210 around its own axis. The outer circumference of the drive wheel 220 abuts against the transverse track 300, and the drive wheel 220 rolls on the transverse track 300. The diameter of the drive wheel 220 is R, and the distance that the vehicle platform 210 moves along the first direction after the drive wheel 220 rotates one revolution is π×R.
[0046] In some embodiments, the automated parking system further includes a power unit, which is drive-connected to the drive wheel 220 to rotate the drive wheel 220. The power unit can be an electric motor or an engine. The power unit is fixed to the vehicle carrier platform 210.
[0047] Figure 4 A schematic diagram of the feedback module of this utility model.
[0048] See Figures 2 to 4 The automated parking system also includes a feedback module 400, which comprises a counting gear 410 and a proximity sensor 420. The counting gear 410 is driven by a drive wheel 220, and the angular velocity of the drive wheel 220 during rotation is the same as the angular velocity of the counting gear 410 during rotation.
[0049] The number of teeth on the outer circumference of the counting gear 410 is N. The angular velocities of the counting gear 410 and the drive wheel 220 are the same, so the positioning accuracy of the counting gear 410 is d=π×R / N. That is, for every tooth the counting gear 410 rotates, the drive wheel 220 rotates a distance of π×R / N, and the vehicle platform 210 moves a distance of π×R / N.
[0050] The proximity sensor 420 is fixed on the vehicle platform 210. The proximity sensor 420 is positioned close to and directly facing the counting gear 410, so that the proximity sensor 420 can generate a pulse signal when each tooth passes through a preset position. The proximity sensor 420 is directly facing the tooth on the counting gear 410.
[0051] In this application, a proximity sensor 420 is used to detect the rotation of the counting gear 410 and emit a pulse signal to calculate the moving distance and speed of the vehicle platform 210, so as to be able to adapt to long-term use in wind and sun environment and effectively avoid the impact of rain and snow weather.
[0052] In some embodiments, the counting gear 410 is a structure made of corrosion-resistant metal material or the outer periphery of the counting gear 410 is provided with a corrosion-resistant coating, so that the counting gear 410 can be used in long-term outdoor environments.
[0053] The proximity sensor 420 can be a high-protection-level proximity sensor 420, so that the proximity sensor 420 is not affected by rain, light, humidity and air acidity and alkalinity, ensuring that the proximity sensor 420 can be used in outdoor environments for a long time.
[0054] In some embodiments, the protection level of the proximity sensor 420 is greater than or equal to C2.
[0055] In some embodiments, the upward projection of the counting gear and the proximity sensor is located on the vehicle platform, so that the vehicle platform covers the counting gear and the proximity sensor, thereby effectively preventing rain, snow and other substances from interfering with the counting gear and the proximity sensor, and further protecting the counting gear and the proximity sensor.
[0056] In one embodiment, the drive wheel 220 and the counting gear 410 are connected by a fixed shaft; the two ends of the fixed shaft are respectively connected to the drive wheel 220 and the counting gear 410; the axes of the fixed shaft, the drive wheel 220 and the fixed shaft are coincident, so that the angular velocity of the drive wheel 220 when rotating is the same as the angular velocity of the counting gear 410 when rotating.
[0057] In another embodiment, the drive wheel 220 and the counting gear 410 are connected by a gear transmission, sprocket drive, or other means, as long as the angular velocities between the drive wheel 220 and the counting gear 410 are the same.
[0058] Figure 5 This is a schematic diagram of the modular framework of the three-dimensional parking garage.
[0059] See Figures 2 to 5 In this embodiment, the automated parking system also includes a controller 500. The controller 500 receives pulse signals from the proximity sensor 420 and can count the number of pulse signals X. During the process of the vehicle platform 210 moving from the upper parking space to the parking space, the movement distance L of the vehicle platform 210 can be calculated by counting the number of pulse signals, and L = X × π × R / N.
[0060] The controller 500 receives pulse signals from the proximity sensor 420 in real time and can count the number of pulse signals X. During the process of moving the vehicle carrier 210 from the loading position to the parking position, the travel distance of the vehicle carrier 210 is: L = X × π × R / N.
[0061] The controller 500 calculates the real-time distance S=DL between the vehicle platform 210 and the parking space, and thus calculates the real-time distance between the vehicle platform 210 and the parking space as S=DX×π×R / N.
[0062] In some embodiments, the automated parking system may also include an alarm device for issuing an alarm message when the real-time distance S between the vehicle platform 210 and the parking space is less than a preset distance Y.
[0063] In other embodiments, when the real-time distance between the vehicle carrier 210 and the parking space is zero, the vehicle carrier 210 moves to the parking space within the parking space frame 100 and stops moving.
[0064] In some embodiments, the controller 500 collects the number of pulse signals and can calculate the frequency H of the pulse signals (the unit can be Hz). The moving speed V of the vehicle platform 210 can be calculated from the frequency of the pulse signals: V = H × d = H × π × R / N. By calculating and obtaining the moving speed of the vehicle platform 210, and by outputting power through the power unit, the moving speed of the vehicle platform 210 can be controlled.
[0065] In some implementations, the drive wheel 220 and the feedback module are configured in multiple groups. For example, the feedback module is configured in two, three, or four groups, etc.
[0066] Each counting gear 410 is connected to a drive wheel 220. Multiple counting gears 410 can each emit pulse signals, and the controller 500 can receive multiple pulse signals. The redundant configuration of multiple counting gears 410 ensures the reliability of the detection structure.
[0067] Multiple proximity sensors 420 are electrically connected to the controller 500 so that they can send pulse signals to the controller 500 respectively.
[0068] In some embodiments, the controller 500 can compare the number of multiple pulse signals. When the error value of the number of multiple pulse signals is greater than a preset value, the controller 500 sends a stop command to the power unit, and the power unit stops outputting power, thereby stopping the operation of the vehicle platform 210 and ensuring the stability and safety of the operation of the three-dimensional parking garage.
[0069] Figure 6 This is a control diagram of the control method for the three-dimensional parking garage of this utility model.
[0070] See Figure 6 and combined Figures 1 to 5 Based on the above structure, this application also provides a control method for a multi-level parking garage:
[0071] The diameter R of the drive wheel 220 and the number of teeth N of the counting gear 410 are collected.
[0072] The controller 500 stores the diameter R of the drive wheel 220 and the number of teeth N of the counting gear 410. The controller 500 collects the diameter R and the number of teeth N for calculation.
[0073] Obtain the distance D between the parking space and the entry point. The distance D between the parking space and the entry point is stored in the controller 500. Obtain the distance D between the parking space and the entry point stored in the controller 500 for calculation.
[0074] The number X of pulse signals emitted by the proximity sensor 420 is counted. When the vehicle platform 210 moves, the pulse sensor sends pulse signals to the controller 500, and the controller 500 receives and counts the number N of pulse signals.
[0075] The real-time travel distance L=X×π×R / N of the vehicle platform 210 is calculated, and the real-time distance S=DL between the vehicle platform 210 and the parking space is calculated, thus obtaining the real-time distance S=DX×π×R / N between the vehicle platform 210 and the parking space.
[0076] The controller 500 stores a preset distance Y. When the vehicle platform 210 moves, the controller calculates the real-time distance S between the vehicle platform 210 and the parking space and compares the real-time distance S with the preset distance Y. When the real-time distance S is less than the preset distance Y, the controller 500 sends a signal to the alarm device and controls the alarm device to sound an alarm.
[0077] When the difference between the real-time distance S and the preset distance is zero, the drive wheel 220 is controlled to stop rotating.
[0078] In this application, "counting the number X of pulse signals emitted by the proximity sensor 420" specifically means that multiple proximity sensors 420 and counting gears 410 are correspondingly provided, and multiple proximity sensors 420 can emit pulse signals respectively. The controller 500 can receive multiple sets of pulse signals, compare the number of pulse signals in multiple sets of pulse signals, and determine whether the error value of the number of pulse signals in multiple sets of pulse signals is greater than a preset value.
[0079] When the error value of the number of pulse signals in multiple pulse signal groups exceeds the preset value, the controller 500 sends a stop command to the power unit.
[0080] When the error value of the number of pulse signals in multiple pulse signal groups is less than the preset value, the average value of the number of pulse signals in multiple pulse signal groups is calculated, and this average value is taken as the number of pulse signals X.
