Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, and specifically to a vehicle inspection system. Background Technology

[0002] Automated parking garages, as a modern facility that efficiently utilizes urban space resources and solves parking difficulties, incorporate many advanced technologies and systems in their design and function to ensure safe parking and efficient management of vehicles. Among these, the detection system is a crucial component. Sensors or cameras are used to detect in real time whether a vehicle is parked in a parking space. While patent publication number CN220319228U—a Chinese utility model patent for an elevator-type intelligent automated parking garage—is relevant, it lacks the ability to secure parked vehicles, making them prone to uneven loading and displacement during garage movement. Utility Model Content

[0003] The main purpose of this invention is to provide a vehicle detection system to solve the problem that vehicles in existing elevator-type intelligent automated parking garages are prone to uneven loading and displacement during the parking garage movement process.

[0004] To achieve the above objectives, this utility model provides a vehicle detection system, including a parking garage with an opening and closing door on one side, and four limiting zones arranged in a matrix on the bottom wall of the parking garage. The limiting zones include multiple perforations arranged in a matrix on the bottom wall of the parking garage, and also include a chassis.

[0005] The top of the chassis is fixedly connected to the bottom wall of the parking garage, and a slide rail is fixedly installed along its length. Two moving blocks are slidably installed on the slide rail, and each moving block is connected to a drive mechanism for driving its sliding.

[0006] Each movable block is fixedly equipped with a guide rod and a rotating first lead screw. The guide rod and the first lead screw are arranged side by side along the width direction of the parking garage. The first lead screw is connected to a drive mechanism to rotate it. The first lead screw has a left helical section and a right helical section. Both the left helical section and the right helical section are screwed onto a support block. The support block is slidably sleeved on the guide rod. A lifting mechanism is fixedly installed on the support block. Multiple blocking rods are arranged on the lifting mechanism along the width direction of the parking garage. The blocking rods can be inserted into the through holes.

[0007] The four support blocks are located directly below the parking garage and correspond one-to-one with the four limit zones.

[0008] A preferred design is an open top structure for the chassis.

[0009] A preferred embodiment is that the opening and closing door is a sliding door, and the opening and closing door is slidably connected to the parking garage.

[0010] A preferred embodiment is that the driving mechanism includes a first motor and a second lead screw. The second lead screw is rotatably mounted on the housing and arranged along the length of the slide rail. The base of the first motor is fixedly mounted on the housing, and the output shaft is coaxially connected to the second lead screw.

[0011] A preferred embodiment is that the lifting mechanism includes a cylinder and a lifting plate fixedly mounted on the piston rod of the cylinder, and multiple blocking rods located in the same limiting area are fixedly mounted on the lifting plate, with the cylinder seat of the cylinder fixedly connected to the support block.

[0012] A preferred solution is to install cameras fixedly on the inner ceiling wall of the parking garage.

[0013] A preferred design is a parking garage with a rectangular box structure.

[0014] A preferred embodiment is that the driving mechanism is a second motor, the base of the second motor is fixedly connected to the moving block, and the output shaft is coaxially connected to the first lead screw.

[0015] The beneficial effects of the above scheme are:

[0016] Initially, the four sets of multiple blocking bars do not protrude from the holes. The door opens, the vehicle drives into the parking garage, and the four wheel hubs of the vehicle stop on the four limit zones, with each zone corresponding to the other. Based on the size of the vehicle, the two drive mechanisms start working. The drive mechanisms drive the moving blocks to slide along the slide rail until the first lead screw and guide rod are directly below the limit zone. The drive mechanism then starts working, driving the first lead screw to rotate. The first lead screw has a left-hand helical section and a right-hand helical section. Two support blocks located on the same lead screw move towards the middle of the first lead screw until the lifting mechanism is directly below the corresponding limit zone. The lifting mechanism then starts working, driving multiple blocking bars on it to protrude from the holes. The four sets of blocking bars limit and block the four wheel hubs of the vehicle, effectively preventing uneven loading and translation during the movement of the vehicle in the parking garage.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example:

[0032] like Figures 1-5 As shown, this embodiment provides a vehicle detection system, including a parking garage 1, with an opening and closing door 11 on one side, as... Figure 5As shown, the opening and closing door is a sliding door, which can be slidably connected to the parking garage, thus facilitating vehicles to enter or leave parking garage 1. The opening and closing door uses existing technology and will not be described in detail. A camera (not shown) is fixedly installed on the inner top wall of parking garage 1. The camera performs real-time monitoring. Parking garage 1 has a rectangular box structure. The bottom wall of parking garage 1 has four limiting zones 12 arranged in a matrix. The limiting zones 12 include multiple perforations 13 arranged in a matrix on the bottom wall of parking garage 1. The vehicle detection system also includes a housing 2; the top of housing 2 is an open structure. The top of housing 2 is fixedly connected to the bottom wall of parking garage 1, and a slide rail 3 is fixedly installed along the length of housing 2. Two moving blocks 4 are slidably installed on the slide rail 3, and each moving block 4 is connected to a driving mechanism 5 for driving its sliding. Each movable block 4 is fixedly equipped with a guide rod 41 and a rotatably mounted first lead screw 42. The guide rod 41 and the first lead screw 42 are arranged side by side, and both the guide rod 41 and the first lead screw 42 are arranged along the width direction of the parking garage 1. The first lead screw 42 is connected to a drive mechanism 7 for rotating it, such as... Figure 4 As shown, the first lead screw 42 has a left helical section 420 and a right helical section 421. Both the left and right helical sections 420 and 421 are screwed onto support blocks 6. The support blocks 6 are slidably mounted on the guide rod 41. A lifting mechanism 61 is fixedly mounted on the support blocks 6. Multiple blocking rods 62 are arranged on the lifting mechanism 61 along the width direction of the parking garage 1. The blocking rods 62 can be inserted into the through holes 13. The lifting mechanism 61 includes a cylinder 610 and a lifting plate 611 fixedly mounted on the piston rod of the cylinder 610. Multiple blocking rods 62 located in the same limiting area 12 are fixedly mounted on the lifting plate 611. The cylinder seat of the cylinder 610 is fixedly connected to the support block 6. Driving the cylinder 610 enables the lifting plate 611 to operate. The four support blocks 6 are all located directly below the parking garage 1, and each of the four support blocks 6 corresponds to one of the four limiting areas 12.

[0033] Initially, the four sets of multiple blocking rods 62 do not protrude from the through holes 13. The opening and closing door 11 is opened, and the vehicle drives into the parking garage 1. The four wheel hubs of the vehicle are positioned on the four limit zones 12, and the two correspond one-to-one. According to the size of the vehicle, the two drive mechanisms 5 start to work. The drive mechanism 5 drives the moving block 4 to slide along the slide rail 3 until the first lead screw 42 and the guide rod 41 are located directly below the limit zone 12. The drive mechanism 7 starts to work and drives the first lead screw 42 to rotate. The first lead screw 42 has a left helical section 420 and a right helical section 421. The two support blocks 6 on the same first lead screw move towards the middle of the first lead screw 42 until the lifting mechanism 61 is located directly below the corresponding limit zone 12. The lifting mechanism 61 is driven to work. The lifting mechanism 61 drives the multiple blocking rods 62 on it to protrude from the through holes 13. The four sets of blocking rods 62 limit and block the four wheel hubs of the vehicle, which effectively prevents the parking garage 1 from being overloaded or shifted during movement.

[0034] The driving mechanism 5 includes a first motor 51 and a second lead screw 52. The second lead screw 52 is rotatably mounted on the housing 2 and is arranged along the length of the slide rail 3. The base of the first motor 51 is fixedly mounted on the housing 2, and its output shaft is coaxially connected to the second lead screw 52. The driving mechanism 7 is a second motor. The base of the second motor is fixedly connected to the moving block 4, and the output shaft of the second motor is coaxially connected to the first lead screw 42.

[0035] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
