[0019] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] See also Figures 1 to 4 As shown, a parking detection device includes a car 1, a laser radar 2, a detection component 3, a vehicle correction component 4, and a wheel alignment component 5, wherein the car 1 is a prior art, and a car door 11 is provided on one side of the car 1 for opening or closing the car 1 so as to move the vehicle to a designated floor through a lifting system in the prior art. The laser radar 2 is a prior art, and is fixed on a side of the car 1 close to the car door 11 for detecting whether the height of the vehicle meets the requirements. During implementation, the vehicle drives to the side of the car door 11, and the laser radar 2 determines whether the height of the vehicle meets the requirements. When it is detected that the vehicle meets the requirements, the car door 11 opens, and when it is detected that the vehicle is too high and does not meet the required height, the car door 11 cannot be opened.

[0021] The detection assembly 3 includes three vehicle position detection devices 31. The three vehicle position detection devices 31 are respectively located in the car 1 and arranged at intervals along the length direction of the car 1. Specifically, Figure 2 As shown, three vehicle position detection devices 31 are respectively located on the inner wall of one side of the car 1, of which two vehicle position detection devices 31 are respectively located on both sides of the length direction of the car 1, and another vehicle position detection device 31 is located in the middle of the length direction of the car 1 to monitor the dynamic changes of the vehicle during driving. During implementation, the front or rear of the vehicle will pass through the three vehicle position detection devices 31 in sequence, thereby facilitating the detection device to determine the current position of the vehicle.

[0022] Preferably, the car 1 is provided with an acoustic and light alarm device in the prior art (not shown in the figure) to remind the owner through the acoustic and light alarm device. That is, when the owner drives the front or rear of the vehicle into the car 1, the vehicle position detection device 31 near the door 11 senses the vehicle entering, and the acoustic and light alarm device can emit a slow prompt sound and emit a green light; when the owner drives the vehicle past the vehicle position detection device 31 located in the middle of the car 1, the acoustic and light alarm device can emit a fast prompt sound and emit a yellow light; when the owner drives the vehicle to the vehicle position detection device 31 located on the side away from the door 11, the acoustic and light alarm device can emit a very fast prompt sound and emit a red light, and then the acoustic and light alarm device is used to indicate to the owner that the vehicle is about to arrive at the designated position. It should be noted that the vehicle position detection device 31 of the present invention is a prior art, and specifically can be an optical sensor, an ultrasonic sensor, a visual sensor or an infrared sensor in the prior art, which will not be repeated here.

[0023] See also Figure 3 As shown, the vehicle correction component 4 is used to correct the vehicle, that is, to make the central axis of the vehicle collinear with the central axis of the car 1, thereby improving the parking accuracy of the vehicle in the car 1, and avoiding the vehicle from being parked crookedly, which causes the center of gravity of the car 1 to be unstable when it rises, thereby causing safety hazards. Specifically, the vehicle correction component 4 includes two horizontally arranged push rods 41 and a power unit 43, the central axes of the two push rods 41 are parallel to the central axis of the car 1, that is, parallel to the length direction of the car 1, and the two push rods 41 are respectively located on both sides of the width direction of the car 1, and the power unit 43 is used to drive the two push rods 41 to move in a direction close to or away from each other.

[0024] During implementation, after the vehicle is parked at the designated position, the power unit 43 is started, and the power unit 43 drives the two push rods 41 to move toward the vehicle until the two push rods 41 respectively contact the tires on the left and right sides of the vehicle, thereby correcting the parking position of the vehicle to prevent the vehicle from being parked crookedly, causing an unstable center of gravity when the car 1 rises.

[0025] Preferably, two pressure sensors 42 are fixedly arranged on the side of each push rod 41 close to the vehicle, and the two pressure sensors 42 on each push rod 41 correspond to the two wheels on the corresponding side. During implementation, the power unit 43 drives the two push rods 41 to move in the direction close to the vehicle. When the vehicle is parked crookedly, one of the pressure sensors 42 on the push rod 41 will abut against the corresponding tire, while the other cannot contact the corresponding tire. At this time, it is judged that the vehicle is crooked, and the power unit 43 continues to drive the two push rods 41 to move in the direction close to each other until each pressure sensor 42 on the push rod 41 abuts against the corresponding wheel. At this time, it is judged that the vehicle has been straightened.

[0026] In this embodiment, a first accommodating space 12 is provided on the bottom surface of the car 1, and the power unit 43 is arranged in the first accommodating space 12. Specifically, the power unit 43 includes a first double-axis motor 431, a first left-handed threaded rod 432, a first right-handed threaded rod 433, two moving blocks 434, and two connecting blocks 435, wherein the first double-axis motor 431 is fixed in the first accommodating space 12, the first left-handed threaded rod 432 and the first right-handed threaded rod 433 are respectively fixed at two output ends of the first double-axis motor 431, the two moving blocks 434 are respectively slidably arranged in the first accommodating space 12, and are respectively screwed with the first left-handed threaded rod 432 and the first right-handed threaded rod 433, the two connecting blocks 435 are respectively fixed at the top ends of the two moving blocks 434, and the two moving blocks 434 are fixedly connected with the corresponding push rods 41 through the two connecting blocks 435.

[0027] During implementation, the first dual-axis motor 431 is started, and the first dual-axis motor 431 drives the first left-handed threaded rod 432 and the first right-handed threaded rod 433 to rotate forward or reverse, thereby driving the two moving blocks 434 respectively screwed with the first left-handed threaded rod 432 and the first right-handed threaded rod 433 to move toward or away from each other, thereby driving the two push rods 41 to move toward or away from each other through the two connecting blocks 435 to clamp and straighten the vehicle. It should be noted that the top surface of the first accommodating space 12 is provided with a clearance groove 121 to make way for the connecting block 435 during the movement.

[0028] Preferably, the bottom surface of the car 1 is provided with second accommodating spaces 13 on both sides of the length direction of the car 1, and two moving blocks 434 are slidably connected in the two second accommodating spaces 13, and a connecting block 435 is fixed on the top of each moving block 434, and is fixedly connected to the corresponding push rod 41 through the connecting block 435. A yielding groove 121 is opened on the top surface of each second accommodating space 13 to yield the connecting block 435 during the movement. By setting up two second accommodating spaces 13, the moving blocks 434 and the connecting blocks 435 slidably arranged in the second accommodating spaces 13 are matched to make the push rod 41 move more smoothly. Preferably, power parts 43 can also be respectively arranged in the second accommodating spaces 13 to further improve the clamping force of the two push rods 41 on the vehicle.

[0029] Figure 2 Combined with Figures 5 to 7 As shown, in this embodiment, the wheel positioning assembly 5 is used to position the wheels of the vehicle, and there are four wheel positioning assemblies 5, which are arranged in a rectangular array on the bottom surface of the car 1. Specifically, the bottom surface of the car 1 is provided with four grooves 14, and the four wheel positioning assemblies 5 are respectively arranged in the four grooves 14. When the vehicle stops at a preset position, the four wheels of the vehicle are respectively located above the four wheel positioning assemblies 5.

[0030] Each wheel alignment assembly 5 includes a first stop roller 51, a second stop roller 52 and a plurality of support rollers 53. The first stop roller 51 and the second stop roller 52 are respectively arranged on both sides of the groove 14 close to the length direction of the car 1. The plurality of support rollers 53 are located between the first stop roller 51 and the second stop roller 52. A first lifting assembly 54 and a second lifting assembly 55 are respectively provided below the first stop roller 51 and the second stop roller 52 for respectively driving the first stop roller 51 and the second stop roller 52 to move away from or close to the groove 14.

[0031] During implementation, when the vehicle is parked in the car 1, the four wheels of the vehicle are respectively located above the plurality of support rollers 53. At this time, the first lifting assembly 54 and the second lifting assembly 55 are started to move the first stop roller 51 and the second stop roller 52 away from the groove 14, thereby positioning the wheels to prevent the vehicle from leaving the parking area due to the owner forgetting to pull the handbrake or operating errors.

[0032] In one embodiment of the present invention, the first lifting assembly 54 and the second lifting assembly 55 of the wheel alignment assembly 5 can work in conjunction with three vehicle position detections at the same time. Specifically, when the front or rear of the vehicle passes the vehicle position detection located in the middle of the car 1, the two wheels located at the front or rear of the vehicle have passed the two wheel alignment assemblies 5 located near the door 11. At this time, the first lifting assembly 54 of each wheel alignment assembly 5 is started, whereby, when the vehicle travels to the preset position, the four wheels will be stopped by the four first stop rollers 51 respectively, thereby limiting the position of the vehicle to prevent the vehicle from passing the wheel alignment assembly 5 and avoiding the driver's operating error, causing the vehicle to collide with the side of the car 1 away from the door 11. When the four wheels of the vehicle are respectively located above the four wheel alignment assemblies 5, the second lifting assembly 55 is started, thereby limiting the four wheels of the vehicle respectively above the four wheel alignment assemblies 5.

[0033] See also Figure 6As shown, in this embodiment, the first lifting assembly 54 and the second lifting assembly 55 both include a U-shaped plate 551, a second double-axis motor 552, a second left-handed threaded rod 553, a second right-handed threaded rod 554, two sliders 555 and two connecting rods 556, the first stop roller 51 and the second stop roller 52 are respectively rotatably arranged in the corresponding U-shaped plate 551, the second double-axis motor 552 is fixed in the groove 14, the second left-handed threaded rod 553 and the second right-handed threaded rod 554 are respectively fixedly connected to the two output ends of the second double-axis motor 552, the two sliders 555 are respectively screwed to the second left-handed threaded rod 553 and the second right-handed threaded rod 554, the two connecting rods 556 are respectively located between the two sliders 555 and the bottom surface of the U-shaped plate 551, the bottom ends of the two connecting rods 556 are respectively rotatably connected to the corresponding sliders 555, and the top ends of the two connecting rods 556 respectively extend upwardly and obliquely away from the second double-axis motor 552, and are rotatably connected to the bottom surface of the U-shaped plate 551.

[0034] During implementation, the second double-axis motor 552 is started, and the second double-axis motor 552 drives the second left-handed threaded rod 553 and the second right-handed threaded rod 554 to rotate forward or reversely, thereby driving the two sliders 555 to move toward or away from each other. At this time, the bottom ends of the two connecting rods 556 move synchronously toward or away from each other, thereby pushing the corresponding U-shaped plate 551 to rise or fall, that is, pushing the corresponding U-shaped plate 551 to move toward or away from the groove 14, thereby driving the first stop roller 51 and the second stop roller 52 to stop and limit the wheel.

[0035] In this embodiment, the central axes of the plurality of support rollers 53 are parallel to the central axes of the first stop roller 51 and the second stop roller 52, and are respectively connected to the groove 14 for rotation. The groove 14 is provided with a stop assembly 56 for preventing the plurality of support rollers 53 from rotating. In implementation, when the vehicle enters, the stop assembly 56 can prevent the plurality of support rollers 53 from rotating. When the wheels of the vehicle are located above the plurality of support rollers 53 and the first stop roller 51 and the second stop roller 52 are both raised, the stop assembly 56 no longer prevents the plurality of support rollers 53 from rotating. Thus, the first stop roller 51, the second stop roller 52 and the plurality of support rollers 53 can prevent the vehicle from moving. Even if the vehicle is in a power state (wheel rotation state), the power of the wheel can be offset by the plurality of support rollers 53 for rotation, so as to prevent the vehicle from being separated from the wheel alignment assembly 5 due to the vehicle owner's operating error (accidental vehicle start) during the vehicle transfer process.

[0036] In this embodiment, a fixing block 561 is fixed in the groove 14, and two through grooves 5611 are formed inside the fixing block 561. The two through grooves 5611 are arranged at intervals along the axial direction of the support roller 53, and the length direction of the two through grooves 5611 is perpendicular to the axial direction of the support roller 53. Figure 7 As shown, the stop assembly 56 includes a plurality of abutment blocks 562 and two push plates 563. The two push plates 563 are respectively slidably arranged in two through grooves 5611. The sliding direction of the push plates 563 is parallel to the length direction of the through grooves 5611. The plurality of abutment blocks 562 correspond one-to-one to the plurality of support rollers 53 and are respectively arranged under the plurality of support rollers 53. Both ends in the length direction of each abutment block 562 respectively pass through the top surface of the fixed block 561 and extend into the corresponding through groove 5611, and are slidably connected to the fixed block 561.

[0037] Specifically, each abutment block 562 includes an abutment plate 5621 and two sliding bars 5622, the abutment plate 5621 is arc-shaped, and the top surface of the abutment plate 5621 is adapted to the outer wall of the support roller 53, and a through hole 5612 is respectively opened on the top surface of the fixed block 561 corresponding to each sliding bar 5622, and each sliding bar 5622 respectively passes through the corresponding through hole 5612 and extends to the inside of the through groove 5611, and is respectively slidably connected with the corresponding through hole 5612, and an arc-shaped protrusion 5631 is respectively convexly provided on the top surface of the push plate 563 corresponding to each abutment block 562, and a recess 5632 is formed between the two protrusions 5631, when the top end of the protrusion 5631 contacts the bottom end of the abutment block 562, the top end of the abutment block 562 is frictionally connected with the corresponding support roller 53 to prevent the support roller 53 from rotating, and when the bottom end of the abutment block 562 is located in the recess 5632, the support roller 53 can rotate. That is, by sliding the push plate 563, the bottom end of the abutment block 562 is located above the protrusion 5631 or in the concave portion 5632, so that the plurality of support rollers 53 rotate past the stop.

[0038] See also Figure 7 As shown, in this embodiment, the second lifting assembly 55 is fixed with two Z-shaped plates 57 for driving the two push plates 563 to slide back and forth along the through groove 5611. Specifically, the two Z-shaped plates 57 are fixed at intervals on the bottom surface of the U-shaped plate 551 of the second lifting assembly 55. One ends of the two push plates 563 extend toward the directions of the two Z-shaped plates 57 respectively, and are respectively provided with slots 5633 that pass through from top to bottom, and the two Z-shaped plates 57 are respectively inserted into the two slots 5633.

[0039] Each Z-shaped plate 57 includes a first vertical plate 571, an arc-shaped plate 572, and a second vertical plate 573. The top of the first vertical plate 571 is fixedly connected to the U-shaped plate 551, the top of the arc-shaped plate 572 is fixedly connected to the bottom of the first vertical plate 571, and the bottom of the arc-shaped plate 572 extends away from the through slot 5611 and is fixedly connected to the top of the second vertical plate 573. In implementation, when the first vertical plate 571 is located in the slot 5633, the protrusion 5631 contacts the bottom end of the abutment block 562, and when the second vertical plate 573 is located in the slot 5633, the bottom end of the abutment block 562 is located in the lower recess 5632.

[0040] During implementation, when the second stop roller 52 is located inside the groove 14, the first vertical plate 571 of the Z-shaped plate 57 is located in the slot 5633, and at this time, the plurality of protrusions 5631 are located directly below the plurality of abutment blocks 562, and the top surface of each abutment block 562 abuts against the corresponding support roller 53 to prevent the plurality of support rollers 53 from rotating. When the second lifting assembly 55 drives the second stop roller 52 to rise, the Z-shaped plate 57 moves upward synchronously until the second vertical plate 573 of the Z-shaped plate 57 is located in the slot 5633, thereby causing the push plate 563 to move toward the second lifting assembly 55, and at this time, the plurality of abutment blocks 562 move toward the groove 14, and the bottom ends of the abutment blocks 562 are located in the lower recess 5632, so that the plurality of abutment blocks 562 no longer abut against the plurality of support rollers 53.

[0041] During the specific implementation of the present invention, the owner drives the vehicle to the side of the door 11 of the car 1, and the laser radar 2 determines whether the height of the vehicle meets the requirements. When it is detected that the vehicle meets the requirements, the door 11 opens. Then the owner drives the vehicle into the car 1. When the front or rear of the vehicle passes the vehicle position detection located in the middle of the car 1 (here the owner drives the vehicle forward into the car 1 or enters the car 1 by reversing), the first lifting assembly 54 of each wheel alignment assembly 5 is started, whereby the four wheels are stopped by the four first stop rollers 51 respectively, to prevent the vehicle from passing the wheel alignment assembly 5, and to prevent the driver's operating error from causing the vehicle to collide with the side of the car 1 away from the door 11. When the four wheels of the vehicle are respectively located above the four wheel alignment assemblies 5, the second lifting assembly 55 is started, whereby the four wheels of the vehicle are respectively restricted above the four wheel alignment assemblies 5.

[0042] At the same time, as the second lifting assembly 55 rises, the Z-shaped plate 57 moves upward synchronously. During this process, the protrusion 5631 of the push plate 563 moves horizontally away from the abutment block 562 until the second vertical plate 573 of the Z-shaped plate 57 is located in the slot 5633. At this time, the bottom end of the abutment block 562 is located in the lower recess 5632, so that the multiple abutment blocks 562 no longer abut against the multiple support rollers 53, thereby restricting the vehicle to the four wheel alignment assemblies 5.

[0043] Next, the power unit 43 of the vehicle correction component 4 is started, and the power unit 43 drives the two push rods 41 to move in the direction close to the vehicle until the two push rods 41 respectively contact the tires on the left and right sides of the vehicle, and until each pressure sensor 42 on the push rod 41 respectively contacts the corresponding wheel. At this time, it is judged that the vehicle is straightened, thereby improving the parking accuracy of the vehicle in the car 1, avoiding the vehicle from being parked crookedly, resulting in an unstable center of gravity when the car 1 rises, and causing safety hazards. It should be noted that in this embodiment, a controller 6 in the prior art is provided in the car 1, and the controller 6 is electrically connected to the door 11, the laser radar 2, the detection component 3, the vehicle correction component 4 and the wheel alignment component 5 respectively.
