Description

Technical Field

[0001] This application relates generally to the technical field of parking detection, and more specifically to a handbrake detection component, method, pre-parking platform, and parking positioning detection device. Background Technology

[0002] With the increasing prevalence of vehicles, the pre-parking platform industry is booming, and new intelligent and digital pre-parking platforms are emerging. In an intelligent pre-parking platform, once a vehicle enters a designated location, the equipment system at that location performs necessary status checks on the vehicle. When parking requirements are met, a vehicle transfer trolley automatically completes the parking process, including vehicle transfer. Among the vehicle status checks, detecting the handbrake engagement is extremely important, as only with the handbrake engaged can the vehicle accurately maintain its position and be securely transferred to the parking space by the transfer trolley. Conversely, if the handbrake is not engaged, inaccurate positioning could lead to collisions, falls, or other accidents.

[0003] Therefore, there is a need to provide a handbrake detection component, method, pre-parking platform, and parking positioning detection device to at least partially solve the above problems. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, a first aspect of this application provides a handbrake detection component, the handbrake detection component comprising:

[0006] support;

[0007] A pusher member, which is movably disposed along a first direction and has a retracted position and an extended position, the pusher member having an abutment portion for contacting the wheel of a vehicle;

[0008] A first driving member, configured to drive the push member to move, is connected to the bracket; and

[0009] An extended position sensor is provided for detecting the pusher located at the extended position.

[0010] When the pusher is in the retracted position, the first drive member can apply a force to the pusher along the first direction from the retracted position to the extended position, so that the pusher pushes the wheel. When the wheel can be pushed and the pusher moves to the extended position, the extended position sensor detects the pusher.

[0011] According to the handbrake detection component of the first aspect of this application, a force is applied to the pusher in a first direction to move it from the retracted position to the extended position. If the pusher can move to the extended position, the extended position sensor can detect the pusher, indicating that the vehicle's wheels can be pushed, and thus indicating that the vehicle's handbrake is not engaged. If the pusher cannot move to the extended position, the extended position sensor cannot detect the pusher, indicating that the vehicle's wheels are not pushed, and thus indicating that the vehicle's handbrake is engaged.

[0012] Optionally, the pusher includes:

[0013] ontology; and

[0014] A roller, rotatably connected to the body, and at least partially projecting out of the surface of the body opposite to the first drive member along the first direction, the roller having an axial direction perpendicular to the first direction, the roller being used to rollably contact the tires of a vehicle.

[0015] Optionally, the handbrake detection assembly further includes a retracted position sensor, which is disposed on the bracket and spaced apart from the extended position sensor, for detecting the pusher in the retracted position.

[0016] Optionally, the handbrake detection assembly further includes a guide wheel connected to the bracket. The guide wheel is located at least on the lower side of the pusher and on opposite sides along the second direction, and the guide wheel can roll into contact with the pusher. The axis of the guide wheel is perpendicular to the first direction, and the second direction is a horizontal direction perpendicular to the first direction.

[0017] Optionally, the pusher further includes:

[0018] A wheel axle, the wheel axle being connected to an end of the body along the first direction; and

[0019] A limiting part is located on the upper and lower sides of the axle between two adjacent rollers. The limiting part is fixedly disposed to the body and connected to the axle.

[0020] A second aspect of this application provides a handbrake detection method, which detects the handbrake status of a vehicle using the aforementioned handbrake detection component. The handbrake detection method includes the following steps:

[0021] The pusher is returned to the retracted position;

[0022] Position the vehicle in a position that abuts against or is close to the abutting part of the pusher;

[0023] The first driving member applies a force along the first direction to the pushing member, moving it from the retracted position toward the extended position, so that the pushing member pushes the wheel. If the wheel can be pushed and the pushing member moves to the extended position, the extended position sensor detects the pushing member and determines that the vehicle handbrake is not engaged; if the wheel is not pushed and the extended position sensor does not detect the pushing member, it is determined that the vehicle handbrake is engaged.

[0024] According to the handbrake detection method of the second aspect of this application, when the pusher is reset to the retracted position, the vehicle is positioned to abut or be close to the pusher, awaiting detection. Then, a force in a first direction is applied to the pusher by the first drive member, causing the pusher to push towards the wheel. If the wheel can be pushed and the extended position sensor can detect the pusher, it is determined that the vehicle's handbrake is not engaged. If the wheel is not pushed and the extended position sensor does not detect the pusher, it is determined that the vehicle's handbrake is engaged. Using the handbrake detection method of this application, the handbrake status can be conveniently and reliably detected, thus preparing for subsequent parking and contributing to the safety and stability of subsequent parking operations.

[0025] A third aspect of this application provides a pre-parking platform for pre-positioning vehicles, the pre-parking platform comprising:

[0026] A vehicle support assembly includes two support surfaces extending along a third direction and spaced apart along a second direction. The support surfaces are used to contact the wheels of the vehicle to support the vehicle. The support surfaces have a first end and a second end opposite to each other along the third direction.

[0027] According to the aforementioned handbrake detection assembly, the bracket of the handbrake detection assembly is movably disposed at the first end of the bearing surface along the height direction between a detection position and a clearance position. The push member located at the detection position at least partially protrudes from the bearing surface to allow the push member to contact the wheel, while the push member located at the clearance position does not extend beyond the bearing surface to allow the wheel to pass. The height direction is perpendicular to the bearing surface.

[0028] A second driving member, located below the bearing surface and connected to the bracket, drives the bracket to move between the detection position and the avoidance position.

[0029] According to the pre-parking platform of the third aspect of this application, when the left and right wheels of the vehicle are respectively located on two bearing surfaces, a force is applied to the pushing member along the first direction from the retracted position to the extended position. This allows the pushing member to apply a force from the first end to the second end to the contacting wheel. If the pushing member can move to the extended position, the extended position sensor can detect the extended position signal, indicating that the vehicle's wheels can be pushed, and thus the vehicle's handbrake is not engaged. If the pushing member cannot move to the extended position, the extended position sensor cannot detect the extended position signal, indicating that the vehicle's wheels are not pushed, and thus the vehicle's handbrake is engaged. Furthermore, the second driving member can drive the bracket to move. When the bracket is in the detection position, the handbrake detection component can detect whether the handbrake is engaged. When the bracket is in the avoidance position, it allows the vehicle's wheels to pass over the bearing surface where the handbrake detection component is located. This ensures vehicle passability while fully utilizing the space below the bearing surface and reducing the space occupied by the bearing surface along the second direction.

[0030] Optionally, the bracket is rotatably connected to the vehicle carrier assembly about a first pivot axis, and the second drive member is rotatably connected to the bracket about a second pivot axis, the first pivot axis and the second pivot axis being parallel to the second direction.

[0031] Optionally, the vehicle support assembly includes a fixed support portion and a movable support portion. The upper part of the fixed support portion forms a fixed support surface, and the upper part of the movable support portion forms a movable support surface. The movable support portion is connected to a bracket. When the handbrake detection assembly is in the avoidance position, the movable support surface is flush with the fixed support surface to form the support surface.

[0032] The pre-parking platform also includes a controller and a signal output component. The controller is connected to the retracted position sensor, the extended position sensor, the signal output component, the first drive member, and the second drive member. The controller controls the first drive member to move the push member between the extended position and the retracted position, and controls the second drive member to move the bracket between the detection position and the avoidance position.

[0033] During the process of the pusher moving to the extended position, if the controller receives the extended position signal detected by the extended position sensor within a preset time, it determines that the handbrake is not engaged and outputs the result of the determination to the signal output component; if the controller does not receive the extended position signal detected by the extended position sensor within the preset time, it determines that the handbrake is engaged and outputs the result of the determination to the signal output component.

[0034] Optionally, the pre-parking platform further includes a wheel alignment assembly, which is disposed on a support member to abut against the vehicle's wheels. The wheel alignment assembly is connected to the handbrake detection assembly, and the wheel alignment assembly includes:

[0035] The main body is movably disposed and formed with a detection position and a avoidance position, wherein, in the detection position, the main body at least partially protrudes from the bearing surface; in the avoidance position, the main body is not higher than the bearing surface to allow vehicles to pass.

[0036] A triggering member is movably disposed at one end of the main body and has a starting position and a compression position. The triggering member is used to contact the wheel and can be pressed by the wheel from the starting position to the compression position.

[0037] An elastic member, connected to the triggering member, for applying a force toward the starting position to the triggering member; and

[0038] A wheel detection component for detecting the trigger component located at the compression position.

[0039] A fourth aspect of this application provides a parking positioning detection device, wherein the handbrake detection component is movably disposed along the height direction and forms a detection position and an avoidance position, and the parking positioning detection device includes:

[0040] Based on the aforementioned handbrake detection component; and

[0041] A wheel alignment assembly is provided for positioning a vehicle in a position that abuts against or is close to the abutting portion of the pusher, and the wheel alignment assembly is connected to the handbrake detection assembly.

[0042] According to the parking positioning detection device of the fourth aspect of this application, the vehicle is positioned in a position that abuts or is close to the abutting part of the pusher by the wheel positioning component, and the handbrake detection component detects whether the handbrake of the vehicle is tightened, thereby ensuring that the vehicle can be parked reliably and stably, thereby helping to improve the safety of vehicle parking.

[0084] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art.

Moreover, for example, the term “first component” does not imply the existence of a “second component”, and the term “second component” does not imply the existence of a “first component”.

[0087] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0088] This application provides a handbrake detection component. For example... Figures 1 to 6As shown, the handbrake detection assembly according to this application may include a bracket 120, a pusher 121, a first drive member 124, a retracted position sensor 125, and an extended position sensor 126. The pusher 121 is movably connected to the bracket 120 along a first direction D1 between a retracted position and an extended position. That is, the pusher 121 is movable relative to the bracket 120 along the first direction D1, and can move from the retracted position to the extended position, and vice versa. The movable connection of the pusher 121 to the bracket 120 can be direct or indirect. The pusher 121 has an abutment portion for contacting the vehicle's wheels. The first drive member 124 may include a fixed portion and a movable portion. The movable portion is movably connected to the fixed portion along the first direction D1. The fixed portion can be directly or indirectly connected to the bracket 120. For example, the fixed portion may be an extension connected to the bracket 120 or other structures connected to the bracket 120. The fixed portion is fixedly disposed relative to the bracket 120. The movable part is connected to the pusher 121 to apply a force along the first direction D1 to the pusher 121 to move it from the retracted position to the extended position. The fixed part is closer to the pusher 121 in the retracted position than to the pusher 121 in the extended position. That is, when the pusher 121 is in the retracted position, the pusher 121 is closer to the fixed part; when the pusher 121 is in the extended position, the pusher 121 is farther from the fixed part. The extended position sensor 126 is provided to the bracket 120. The extended position sensor 126 is used to detect the pusher 121 in the extended position.

[0089] When the pusher 121 is in the retracted position, the first drive member 124 can apply a force to the pusher 121 in a first direction to move it from the retracted position to the extended position, so that the pusher 121 pushes the wheel. When the wheel can be pushed and the pusher 121 moves to the extended position, the extended position sensor detects the pusher 121.

[0090] According to the handbrake detection component of this application, a force is applied to the pusher 121 by the first drive member 124 to move it from the retracted position to the extended position along the first direction D1. If the pusher 121 can move to the extended position, the extended position sensor 126 can detect the pusher 121, indicating that the vehicle's wheels can be pushed, and thus indicating that the vehicle's handbrake is not engaged. If the pusher 121 cannot move to the extended position, the extended position sensor 126 cannot detect the pusher 121, indicating that the vehicle's wheels are not pushed, and thus indicating that the vehicle's handbrake is engaged.

[0091] See Figure 1 , Figure 2 and Figure 6A retractable position sensor 125 is mounted on the bracket 120 and spaced apart from the extended position sensor 126 to detect the pusher 121 in the retracted position. For example, the extended position sensor 126 and the retractable position sensor 125 can be spaced apart along one or both of the height direction D4 and the first direction D1. Here, the height direction D4 can be understood as the vertical direction or the plumb line direction. The retractable position sensor 125 can be used for timing, allowing the determination of whether the vehicle's wheels are being pushed based on whether the pusher 121 is detected within a preset time, thereby indirectly determining whether the vehicle's handbrake is engaged. For example, timing can begin when the retractable position sensor 125 no longer detects the pusher 121 as it moves from the retracted position to the extended position. When the preset time is reached, if the extended position sensor 126 does not detect the pusher, it can be determined that the vehicle's handbrake is engaged; if the extended position sensor 126 detects the pusher, it can be determined that the vehicle's handbrake is not engaged.

[0092] Of course, in some other application scenarios of this application, if the vehicle is parked in a preset position and the vehicle's wheels abut against the abutment portion of the pusher 121 in the retracted position, the retracted position sensor 125 may continuously detect the pusher 121 as the pusher moves from the retracted position to the extended position to apply thrust to the wheels. In this case, using the time when the retracted position sensor 125 no longer detects the pusher 121 as the timing starting point may not be appropriate. In this case, the time when the controller sends a control command to the first drive member 124 can be used as the timing starting point.

[0093] Continue reading Figure 1 , Figure 2 and Figure 6 For example, the pusher 121 may include a body 122 and a roller 123. The roller 123 is rotatably connected to the body 122. The roller 123 protrudes at least partially from the surface of the body 122 opposite to the first drive member 124 along a first direction D1. The axial direction of the roller 123 is perpendicular to the first direction D1. The roller 123 is used to make rolling contact with the tire of the vehicle. Here, the roller 123 is configured as the aforementioned abutment portion. Because the roller 123 makes rolling contact with the tire of the vehicle, it helps to reduce friction between the pusher 121 and the wheel, thereby helping to protect the wheel.

[0094] exist Figure 1 and Figure 2 In the example shown, the body 122 includes an outwardly protruding detection section 122a. The retracted position sensor 125 and the extended position sensor 126 are respectively disposed at both ends of the stroke of the detection section 122a.

[0095] Furthermore, the detection unit 122a can be configured as a protrusion. The retracted position sensor 125 and the extended position sensor 126 can be configured as limit switches. The roller at the end of the limit switch is used to abut against the protrusion. That is, when the pusher 121 is in the retracted position, the protrusion abuts against the end roller of the limit switch, which serves as the retracted position sensor 125; when the pusher 121 is in the extended position, the protrusion abuts against the end roller of the limit switch, which serves as the extended position sensor 126.

[0096] Continue reading Figure 1 , Figure 2 and Figure 6 Furthermore, the rollers 123 are spaced apart along the second direction D2. By spaced the rollers 123 along the second direction D2, compared to continuous arrangement, the cost of the rollers 123 can be reduced. At the same time, it also ensures that the force on each roller 123 is balanced.

[0097] See Figures 1 to 6 The pushing member 121 may further include an axle 128 and a limiting portion 129. The axle 128 is connected to the end of the body 122 along the first direction D1. The limiting portion 129 is located on the upper and lower sides of the axle 128 between two adjacent rollers 123. The limiting portion 129 is fixedly disposed to the body 122 and connected to the axle 128. By providing the limiting portion 129, the strength of the connection structure between the axle 128 and the body 122 can be increased.

[0098] exist Figure 6 In the example shown, the axle 128 is fastened to the end of the body 122 by fasteners. A limiting portion 129 can be configured as a limiting block. Two limiting blocks are provided between two adjacent rollers 123. The two limiting blocks are located on the upper and lower sides of the axle 128, respectively, along its diameter. One end of the limiting block can be welded to the body, and the other end is connected to the axle 128. This restricts the displacement of the axle 128 along the aforementioned diameter direction, thereby helping to improve the strength of the connection structure between the axle 128 and the body 122, making the connection between the axle 128 and the body 122 more stable.

[0099] See also Figure 1 , Figure 2 and Figure 6Furthermore, the handbrake detection assembly may also include a guide wheel 127. The guide wheel 127 is connected to the bracket 120. The guide wheel 127 is located at least on the underside of the push member 121 and on opposite sides along the second direction D2. The guide wheel 127 is rollably in contact with the push member 121. The axial direction of the guide wheel 127 is perpendicular to the first direction D1. The second direction D2 is a horizontal direction perpendicular to the first direction D1. The guide wheel 127 located on the underside of the push member 121 can provide support force to the push member 121 while maintaining roll contact with it, thereby reducing friction between the push member 121 and the guide wheel 127. The guide wheels 127 located on opposite sides of the push member 121 along the second direction D2 can limit the push member 121 along the second direction D2 while maintaining roll contact with it. During the movement of the pusher 121 along the first direction D1, the movement direction of the pusher 121 is guided by the rolling cooperation between each guide wheel 127 and the pusher 121, making the movement of the pusher 121 smoother.

[0100] See also Figure 1 and Figure 2 Optionally, the first drive member 124 can be configured as a first hydraulic cylinder. The piston rod of the first hydraulic cylinder is connected to the push member 121. The cylinder body of the first hydraulic cylinder constitutes the fixed part described above. The piston rod of the first hydraulic cylinder constitutes the movable part described above.

[0101] See Figures 1 to 6 This application also provides a handbrake detection method, which detects the handbrake status of a vehicle using the aforementioned handbrake detection component. The handbrake detection method may include the following steps:

[0102] Return the pusher 121 to the retracted position;

[0103] Position the vehicle in a position that abuts against or is close to the abutting part of the pusher 121;

[0104] The first driving member applies a force to the pusher 121 along the first direction D1, moving it from the retracted position to the extended position, so that the pusher 121 pushes the wheel. If the wheel can be pushed and the pusher 121 moves to the extended position, the extended position sensor 126 detects the pusher 121 and determines that the vehicle handbrake is not engaged. If the wheel is not pushed and the extended position sensor 126 does not detect the pusher 121, it determines that the vehicle handbrake is engaged.

[0105] According to the handbrake detection method of this application, when the pusher 121 is reset to the retracted position, the vehicle is positioned to abut or be close to the pusher 121 to await detection. Then, a force along the first direction D1 is applied to the pusher 121 by the first drive member, causing the pusher 121 to push towards the wheel. If the wheel can be pushed and the extended position sensor 126 can detect the pusher 121, it is determined that the vehicle handbrake is not engaged. If the wheel is not pushed and the extended position sensor 126 does not detect the pusher 121, it is determined that the vehicle handbrake is engaged. Using the handbrake detection method of this application, the handbrake status can be detected conveniently and reliably, thus preparing for subsequent parking and contributing to the safety and stability of subsequent parking operations.

[0106] In one example of this application, the vehicle can be positioned to abut or be close to the abutment portion of the pusher 121 during the process of resetting the pusher 121 to the retracted position. This is as long as the pusher 121 is reset to the retracted position before the vehicle is positioned to abut or be close to the abutment portion of the pusher 121.

[0107] In another example of this application, the pusher 121 can be returned to the retracted position first, and then the vehicle can be positioned to abut or be close to the abutment portion of the pusher 121.

[0108] See Figures 1 to 6This application also provides a pre-parking platform 100 for pre-positioning a vehicle. The pre-parking platform 100 may include a vehicle support assembly 110, a handbrake detection assembly as described above, and a second drive member 113. The vehicle support assembly 110 may include two support surfaces. The support surfaces extend along a third direction D3 and are spaced apart along a second direction D2. The support surfaces are used to contact the wheels of the vehicle to support the vehicle, i.e., the support surfaces are used to support the vehicle. The support surfaces have a first end and a second end opposite along the third direction D3. The bracket 120 of the handbrake detection assembly is movably disposed along the height direction D4 to the first end of the support surface between a detection position and a avoidance position. The push member 121 located at the detection position protrudes at least partially from the support surface to allow the push member 121 to contact the wheel. For example, at least the abutment portion of the push member 121 located at the detection position is located above the support surface. The pusher 121, located in the avoidance position, does not extend beyond the bearing surface, allowing the wheels to pass over the pusher 121, thus allowing the vehicle to leave the pre-parking platform 100 in the direction from the second end to the first end. This eliminates the need for the vehicle to leave the pre-parking platform 100 in the direction from the first end to the second end, thereby improving the efficiency of vehicle entry and exit from the pre-parking platform 100. The height direction D4 is perpendicular to the bearing surface. The second drive member 113 is located below the bearing surface and connected to the bracket 120 to drive the bracket 120 between the detection position and the avoidance position. When the vehicle needs to detect the handbrake engagement status, the second drive member 113 can drive the bracket 120 to the detection position; after detection, when the vehicle needs to continue moving in the first direction D1 from the second end to the first end, the second drive member 113 can drive the bracket 120 to the avoidance position.

[0109] According to the pre-parking platform 100 of this application, when the left and right wheels of the vehicle are respectively located on two bearing surfaces, the first driving member 124 applies a force along the first direction D1 to the pushing member 121 to move from the retracted position to the extended position. This allows the pushing member 121 to apply a force from the first end to the second end to the contacting wheel. If the pushing member 121 can move to the extended position, the extended position sensor 126 can detect the extended position signal, indicating that the vehicle's wheel can be pushed, and thus the vehicle's handbrake is not engaged. If the pushing member 121 cannot move to the extended position, the extended position sensor 126 cannot detect the extended position signal, indicating that the vehicle's wheel is not pushed, and thus the vehicle's handbrake is engaged. Furthermore, the second driving member 113 can drive the bracket 120 to move. When the bracket 120 is in the detection position, the handbrake detection component can detect whether the handbrake is engaged. When the bracket 120 is in the avoidance position, it allows the vehicle's wheel to pass over the bearing surface where the handbrake detection component is located. This ensures vehicle passability while making full use of the space below the load-bearing surface, reducing the space occupied by the load-bearing surface along the second direction D2.

[0110] See Figure 4 and Figure 5 For example, bracket 120 is rotatably connected to vehicle carrier assembly 110 about a first pivot axis 114. Second drive member 113 is rotatably connected to bracket 120 about a second pivot axis 115. The first pivot axis 114 and the second pivot axis 115 are parallel to a second direction D2. In this example, when the second drive member 113 drives bracket 120 to move, bracket 120 rotates about the first pivot axis 114, thereby causing push member 121 to move between a detection position and an avoidance position.

[0111] See Figure 5 When the bracket 120 is in the avoidance position, the first direction D1 can be parallel to the third direction D3. When the bracket 120 is in the detection position, the first direction D1 can form an acute angle with the third direction D3. The clamping direction of this acute angle faces the second end of the bearing surface.

[0112] Continue reading Figure 4 and Figure 5 Optionally, the second drive member 113 may be configured as a second hydraulic cylinder. The cylinder body of the second hydraulic cylinder is connected to the vehicle carrier assembly 110. The piston rod of the second hydraulic cylinder is connected to the bracket 120 via a second pivot axis 115. As the second hydraulic cylinder drives the bracket 120 to rotate about a first pivot axis 114, the bracket 120 rotates about the second pivot axis 115 relative to the piston rod of the second hydraulic cylinder.

[0113] See also Figure 4 and Figure 5For example, the vehicle support assembly 110 may include a fixed support portion 111 and a movable support portion 112. A fixed support surface is formed on the upper part of the fixed support portion 111. A movable support surface is formed on the upper part of the movable support portion 112. The movable support portion 112 is connected to a bracket 120. When the handbrake detection assembly is in the avoidance position, the movable support surface is flush with the fixed support surface to form a support surface, and the bracket 120 is located below the movable support portion 112.

[0114] The pre-parking platform 100 may further include a controller (not shown) and a signal output component (not shown). The controller is connected to the retraction position sensor 125, the extension position sensor 126, the signal output component, the first drive member 124, and the second drive member 113. The controller determines that the push member 121 is reset to the retraction position based on the retraction position signal detected by the retraction position sensor 125. The controller controls the first drive member 124 to move the push member 121 to the extension position. During the movement of the push member 121 to the extension position, if the controller receives the extension position signal detected by the extension position sensor 126 within a preset time, it determines that the handbrake is not engaged and outputs the result to the signal output component; if the controller does not receive the extension position signal detected by the extension position sensor 126 within the preset time, it determines that the handbrake is engaged and outputs the result to the signal output component. The preset time can start from the disappearance of the retraction position signal detected by the retraction position sensor 125, or it can start from when the controller issues a control command to the first drive member 124 to move the push member 121 to the extension position. The preset time can be set according to actual needs.

[0115] For example, the signal output component may include at least one of an audible and visual alarm (not shown), a voice announcer (not shown), and a display with voice functionality (not shown).

[0116] The pre-parking platform 100 of this application can be used as follows: First, the controller can control the second drive member 113 to move the bracket 120 to the detection position, so that the abutment part of the push member 121 is above the bearing surface. Then, the vehicle is driven from the first end to the second end of the bearing surface into the pre-parking platform 100 until it stops at the designated position on the bearing surface, at which point the abutment part of the push member 121 abuts against the wheel. Next, the controller controls the audible and visual alarm or other voice broadcaster to output prompt information to prompt the driver to engage the handbrake and get out of the vehicle. Then, the status of the handbrake is detected.

[0117] The process of checking the handbrake status may include the following steps:

[0118] The controller controls the first drive member 124 to move the push member 121 to the extended position. During the movement of the push member 121 to the extended position, if the controller does not receive an extended position signal detected by the extended position sensor 126 within a preset time, it determines that the handbrake is engaged and outputs the result to the signal output component. The controller can then control the remaining components of the pre-parking platform 100 to complete other operations. Conversely, if the controller receives an extended position signal detected by the extended position sensor 126 within a preset time, it determines that the handbrake is not engaged and outputs the detection result through the audible and visual alarm and other signal output components to prompt the driver to re-engage the handbrake. Simultaneously, it controls the first drive member 124 to reset, causing the push member 121 to retract to the retracted position. Then, the handbrake status detection process is repeated until the controller receives an extended position signal detected by the extended position sensor 126 and determines that the handbrake is engaged.

[0119] Once the handbrake is detected as engaged, the parking system, including the aforementioned pre-parking platform, will continue to execute subsequent parking actions.

[0120] See Figures 6 to 14 In addition, the pre-parking platform may also include a wheel alignment assembly 200. The wheel alignment assembly 200 is used to position the wheel 300. The wheel alignment assembly 200 is disposed to the support member 210 to abut against the vehicle's wheel. The wheel alignment assembly 200 can be connected to the aforementioned handbrake detection assembly, thereby integrating the two together. The wheel alignment assembly 200 may include a body 220, a trigger member 230, an elastic member 231, and a wheel detection member 250. The body 220 is movably disposed and formed with a detection position and a clearance position. In the detection position, the body 220 at least partially protrudes from the bearing surface. In the clearance position, the body 220 is not higher than the plane on which the wheel 300 travels, allowing the vehicle to pass. The trigger member 230 is movably disposed at one end of the body 220 and formed with a starting position and a compression position. The trigger member 230 is used to contact the wheel 300 and can be pressed from the starting position to the compression position by the wheel 300. The elastic member 231 is connected to the trigger member 230 to apply a force toward the starting position to the trigger member 230. The wheel detection member 250 is used to detect the trigger member 230 in the compressed position.

[0121] The support member 210 may be constructed as a steel frame for ease of fabrication and installation. A vehicle can travel on the support member 210. The support member 210 may include a recess 211. A wheel positioning assembly 200 is disposed within the recess 211. The wheel positioning assembly 200 may be connected to the bottom of the recess 211. The wheel positioning assembly 200 is movable relative to the support member 210 to avoid interfering with the movement of the wheel 300.

[0122] The support member 210 may include a first support portion 213 and a second support portion 214. The first support portion 213 and the second support portion 214 are located on opposite sides of the groove 211 along the vehicle's travel direction. The first support portion 213 may be located in front of the second support portion 214 along the vehicle's travel direction. The first support portion 213 may have an inlet to the support member 210. The vehicle travels through the inlet of the support member 210 onto the first support portion 213 and moves toward the second support portion 214. The first support portion 213 and the second support portion 214 are respectively located on opposite sides of the wheel alignment assembly 200 along the vehicle's travel direction. Here, the first support portion 213 and the second support portion 214 can be understood as the aforementioned bearing surface or as part of the bearing surface.

[0123] The wheel alignment assembly 200 can abut against the vehicle wheel 300 to position the wheel 300. The wheel alignment assembly 200 may include a main body 220. The main body 220 may be connected to the aforementioned bracket 120 or movable part. The main body 220 is pivotally connected to the support member 210 via a pivot shaft 221. The pivot shaft 221 may be the same as the aforementioned first pivot shaft 114. The main body 220 can be pivotally connected to the bottom of the groove 211 via the pivot shaft 221. The wheel alignment assembly 200 may also include a pivot seat 227, which can be fixedly connected to the bottom of the groove 211 by welding. The pivot shaft 221 passes through the pivot seat 227 and is fixedly connected to the pivot shaft 221. The main body 220 may also include a hinge plate 226, with a hinge hole at one end of the hinge plate 226 near the second support part 214. The pivot shaft 221 extends through the hinge hole. The hinge plate 226 is rotatable relative to the pivot axis 221.

[0124] The main body 220 is used to move between a detection position and a avoidance position. The end of the main body 220 in the detection position away from the pivot axis 221 is above the end of the main body 220 in the avoidance position away from the pivot axis 221. The end of the main body 220 in the detection position away from the pivot axis 221 protrudes from the bearing surface.

[0125] The wheel alignment assembly 200 may further include a trigger member 230 for contacting the wheel 300. The trigger member 230 is pivotally connected to the end of the body 220 away from the pivot axis 221. The trigger member 230 is disposed near the first support portion 213. The trigger member 230 is movable with the body 220 between a detection position and an avoidance position. The trigger member 230 in the detection position protrudes from the bearing surface. The trigger member 230 in the detection position is above the trigger member 230 in the avoidance position.

[0126] The trigger member 230 is movable relative to the main body 220. The trigger member 230 is movable between a starting position and a compressed position. The wheel 300 contacts the trigger member 230 and applies a force to it, causing the trigger member 230 in the starting position to move towards the compressed position. The wheel 300 is spaced apart from the trigger member 230 in the starting position, and the trigger member 230 is no longer subjected to the force applied by the wheel 300, thus resetting.

[0127] The wheel alignment assembly 200 may further include an elastic member 231. The elastic member 231 is connected to the trigger member 230. The elastic member 231 is disposed near the first support portion 213. The trigger member 230, located in the initial position, can apply a force to the elastic member 231, causing the elastic member 231 to deform. The elastic member 231 may be located inside the trigger member 230. The elastic member 231 can apply a force to the trigger member 230 toward the initial position. The wheel 300 is spaced apart from the trigger member 230 located in the initial position. The trigger member 230 is not subject to the force applied by the wheel 300. The elastic member 231 applies an elastic force to the trigger member 230, causing the trigger member 230, located in the compressed position, to move toward the initial position.

[0128] The wheel alignment assembly 200 may further include a wheel detection component 250. The wheel detection component 250 is disposed on the main body 220. The wheel detection component 250 may be fixedly connected to the main body 220. The wheel detection component 250 is located below the trigger component 230 to detect the trigger component 230 in the compressed position. The wheel detection component 250 may be a microswitch. The trigger component 230 overcomes the elastic force of the elastic component 231 and contacts the wheel detection component 250. The trigger component 230, in the initial position, moves downward to the compressed position. The trigger component 230 in the compressed position contacts or abuts against the wheel detection component 250, causing the wheel detection component 250 to detect that the wheel 300 is in position.

[0129] The wheel positioning assembly 200 according to this application is disposed on a support member 210 to abut against a vehicle wheel 300. The wheel positioning assembly 200 includes a main body 220, a trigger member 230, an elastic member 231, and a wheel detection member 250. The main body 220 is pivotally connected to the support member 210 about a pivot axis 221 between a detection position and an avoidance position. The trigger member 230 is pivotally connected to the end of the main body 220 away from the pivot axis 221 between a starting position and a compressed position for contacting the wheel 300. The elastic member 231 is in contact with the trigger member 230 to apply a force toward the starting position to the trigger member 230. The wheel detection member 250 is disposed on the main body 220 and located below the trigger member 230 to detect the trigger member 230 in the compressed position. Thus, the trigger member 230 abuts against the wheel 300, and the wheel detection member 250 can detect the trigger member 230 in the compressed position, thereby detecting whether the wheel 300 is in position, providing accurate positioning and ease of operation. Since the main body 220 is not higher than the plane on which the wheels 300 travel when it is in the avoidance position, it allows the vehicle to pass, which in turn helps the vehicle to be moved in the direction of entry.

[0130] To ensure that the triggering member 230 in the initial position can contact the wheel 300, the triggering member 230 in the detection position protrudes from the support member 210. For example... Figure 9 and Figure 12 As shown, the support member 210 has a supporting upper surface 212, which is used to contact the wheel 300 to support the wheel 300. The trigger member 230, located at the detection position, is positioned above the supporting upper surface 212. This ensures that the trigger member 230, located at the detection position, can contact the wheel 300. Figure 10 and Figure 13 As shown, the trigger member 230 located at the detection position can prevent the wheel 300 from continuing to move. The trigger member 230 located at the detection position applies a force to the wheel 300 opposite to the direction of travel of the vehicle to prevent the wheel 300 from continuing to move toward the second support 214.

[0131] like Figure 11 As shown, the main body 220 located at the detection position can move downwards along the height direction of the wheel alignment assembly 200 towards the avoidance position. The wheel 300 can travel on the main body 220 located at the avoidance position. The main body 220 located at the avoidance position can support the wheel 300 to move on the wheel alignment assembly 200. Combined with... Figure 8As shown, the main body 220 has an upper surface 222 for supporting the wheel 300. To ensure stable support of the wheel 300 by the main body 220, the wheel positioning assembly 200 also includes a cover plate 223 located above the main body 220. The cover plate 223 is connected to the upper surface 222. The cover plate 223 can be connected to the main body 220 by welding or bolting. The cover plate 223, positioned in a clearance position, supports the wheel 300, allowing the wheel 300 to travel smoothly on the cover plate 223 in the clearance position.

[0132] Furthermore, such as Figure 14 As shown, cover plate 223 has an upper cover surface 224, which is flush with the upper support surface 212 when in the avoidance position. This allows a vehicle on the support member 210 to smoothly drive onto cover plate 223, reducing vehicle bumps. Trigger member 230 has a trigger surface 232, which is flush with the upper support surface 212 when in the avoidance position. This ensures that trigger member 230 in the avoidance position does not interfere with the movement of wheel 300.

[0133] In order for the main body 220 to move between the detection position and the avoidance position, such as Figure 7 As shown, the wheel alignment assembly 200 also includes a drive member 260 and a fixed seat 262. The fixed seat 262 is fixedly connected to the support member 210. The fixed seat 262 can be fixedly connected to the bottom wall of the groove 211. The drive member 260 is connected to the fixed seat 262. Preferably, the drive member 260 is hinged to the fixed seat 262. The drive member 260 is connected to the main body 220 through the fixed seat 262. The drive member 260 has a movable push rod 261, which can move along the height direction of the wheel alignment assembly 200. The drive member 260 can be a hydraulic cylinder, and the push rod 261 can be the push rod of the hydraulic cylinder. Here, the drive member 260 and the second drive member 113 mentioned above can be the same component.

[0134] Furthermore, push rod 261 is connected to the end of main body 220 away from pivot axis 221 to drive main body 220 to move along the height direction of wheel positioning assembly 200. Push rod 261 can be hinged to main body 220 to adjust the position of main body 220 and trigger member 230, such that trigger member 230 in the detection position protrudes from support member 210, and the triggering upper surface 232 of trigger member 230 in the avoidance position is flush with support upper surface 212.

[0135] In a preferred embodiment, the elastic member 231 can be constructed as a torsion spring. The torsion spring is capable of applying a force to the trigger member 230. Specifically, as... Figure 8As shown, the torsion spring has a torsion spring coil, a first torsion spring arm 233, and a second torsion spring arm 234. The first torsion spring arm 233 and the second torsion spring arm 234 are respectively connected to both ends of the torsion spring coil. The axial direction of the torsion spring coil is perpendicular to the vehicle's travel direction, so that the torsion spring can be subjected to the downward force of the wheel 300.

[0136] Furthermore, the first torsion spring arm 233 abuts against the trigger member 230 to apply an elastic force to the trigger member 230. The second torsion spring arm 234 abuts against the main body 220 to transmit the force applied to the torsion spring by the trigger member 230 to the main body 220.

[0137] The trigger member 230 may further include a sleeve. The lower inner surface of the trigger member 230 may be welded to the sleeve. The axial direction of the sleeve is parallel to the axial direction of the torsion spring. The wheel positioning assembly 200 may further include an axle seat and a pivot. The axle seat is fixedly connected to the body 220. The axle seat is fixedly connected to the end of the body 220 away from the pivot axis 221. The axle seat may be fixedly connected to the side surface 225 of the end of the body 220 away from the pivot axis 221. The axle seat and the body 220 may be connected together by welding.

[0138] A rotating shaft is provided in the axle seat. The axle seat has a shaft hole in which the rotating shaft is disposed. A torsion spring is sleeved on the rotating shaft and is rotatable relative to the rotating shaft. A sleeve is sleeved on the rotating shaft and is rotatable relative to the rotating shaft. A trigger member 230 can drive the sleeve and the torsion spring to rotate relative to the rotating shaft. The trigger member 230 in the initial position is subjected to downward pressure by the wheel 300, which applies a force to the torsion spring coil through the first torsion spring arm 233, causing the torsion spring coil to rotate relative to the rotating shaft. The trigger member 230 in the initial position moves downward toward the compression position under the downward pressure, thereby driving the sleeve to rotate relative to the rotating shaft. The wheel 300 separates from the trigger member 230 in the compression position, and the trigger member 230 moves back to the initial position under the elastic force of the torsion spring, thus keeping the trigger member 230 in the initial position. This prevents the torsion spring from falling off and also prevents the trigger member 230 from separating from the main body 220.

[0139] like Figure 7As shown, the wheel alignment assembly 200 may further include a position detection member 251. The position detection member 251 may be disposed at the end of the main body 220 away from the pivot axis 221. The position detection member 251 may be located below the wheel detection member 250. The position detection member 251 may be an independent limit switch. The position detection member 251 can move with the main body 220 between a detection position and an avoidance position to detect the position of the end of the main body 220 away from the pivot axis 221, thereby providing feedback on whether the trigger member 230 has moved into place. The wheel alignment assembly 200 may further include an entry detection member. The entry detection member may be disposed at the entry point of the support member 210. The entry detection member is used to detect the movement of the wheel 300 to determine whether the vehicle has traveled onto the support member 210.

[0140] In addition, the controller can communicate with the wheel detection component 250. The wheel detection component 250 detects whether the wheel 300 touches the trigger component 230 located at the detection position and feeds a signal back to the controller. The controller is also electrically connected to the position detection component 251. The position detection component 251 detects whether the movement of the end of the main body 220 away from the pivot axis 221 has reached the correct position and feeds a signal back to the controller. The controller is also electrically connected to the entry detection component. The entry detection component detects whether the wheel 300 has traveled to the support component 210 and feeds a signal back to the controller. The controller is also electrically connected to the drive component 260. The controller can send signals to control the upward and downward movement of the push rod 261.

[0141] For example, the entry detection component can detect the wheel 300 traveling to the support component 210. Preferably, the entry detection component can detect the wheel 300 traveling to the first support portion 213. After detecting the wheel 300 traveling to the first support portion 213, the entry detection component sends a signal to the controller.

[0142] The controller receives a signal from the inlet detection component. Based on the signal from the inlet detection component, the controller controls the drive component 260 to move. The controller controls the push rod 261 to move upward, thereby driving the end of the main body 220 away from the pivot axis 221 to move upward, thus causing the trigger component 230, which is in the avoidance position, to move to the detection position.

[0143] The position detection component 251 detects the position of the end of the main body 220 away from the pivot axis 221 and sends a signal to the controller. When the end of the main body 220 away from the pivot axis 221 is in the detection position, the position detection component 251 sends a signal to the controller.

[0144] The controller receives a signal from the position detection component 251. Based on the signal from the position detection component 251, the controller controls the drive component 260, causing the push rod 261 of the drive component 260 to stop moving.

[0145] The vehicle moves toward the wheel alignment assembly 200. The trigger member 230, located in the initial position, contacts the wheel 300. The wheel 300 applies a force to the trigger member 230 in the initial position, causing the trigger member 230 to move downward toward the compression position. The trigger member 230 in the initial position overcomes the elastic force of the elastic member 231 to contact the wheel detection member 250. The wheel detection member 250 detects that the trigger member 230 is in the compression position and sends a signal to the controller.

[0146] The controller receives the signal from the wheel detection component 250 and sends a control signal to the audible and visual alarm device based on the signal. The audible and visual alarm device alerts the driver. The driver then engages the handbrake to stop the vehicle.

[0147] When the detection is complete, the controller sends a control signal to the drive member 260 to control the movement of the drive member 260. The controller controls the push rod 261 to move downward, thereby driving the end of the main body 220 away from the pivot axis 221 to move downward, thereby causing the trigger member 230 located at the detection position to move to the avoidance position.

[0148] When the end of the main body 220 away from the pivot axis 221 is in the avoidance position, the position detection member 251 sends a signal to the controller. The controller receives the signal fed back by the position detection member 251. The controller controls the drive member 260 according to the signal fed back by the position detection member 251, so that the push rod 261 of the drive member 260 stops moving. The triggering upper surface 232 of the triggering member 230 in the avoidance position is flush with the support upper surface 212, and the cover plate upper surface 224 in the avoidance position is flush with the support upper surface 212. The wheel 300 can continue to move toward the second support 214.

[0149] There can be two wheel alignment components 200. The two wheel alignment components 200 correspond to the left and right wheels 300 of the vehicle, respectively, and abut against the left and right wheels 300. According to this application, the wheel alignment components 200 can automatically rise and fall according to signal commands, and are suitable for intelligent garages, inspection equipment, or car wash equipment. They offer precise positioning, are easy to operate, and do not affect the one-way travel of the vehicle.

[0150] This application also provides a parking positioning detection device. A handbrake detection component is movably disposed along the height direction D4 and has a detection position and an avoidance position. The parking positioning detection device may include the aforementioned handbrake detection component and wheel positioning component 200. The wheel positioning component 200 is used to position the vehicle in a position abutting or close to the abutment portion of the pusher. The wheel positioning component 200 may be connected to the handbrake detection component. For example, the wheel positioning component 200 and the handbrake detection component may be integrated into a bracket or mounting base.

[0151] According to the parking positioning detection device of this application, the vehicle is positioned in a position that abuts or is close to the contact part of the pusher by the wheel positioning component, and the handbrake detection component detects whether the vehicle's handbrake is engaged, thereby ensuring that the vehicle can be parked reliably and stably, thus helping to improve the safety of vehicle parking.
