Description

Technical Field

[0001] This invention belongs to the field of vehicle lifting and positioning technology, and more specifically, relates to an intelligent displacement height measurement and positioning system for vehicle lifting. Background Technology

[0002] When using a car lift, a height measurement and positioning system is usually required to control the components and move the vehicle to the appropriate height for convenient vehicle maintenance.

[0003] For example, application number CN201510337934.9 discloses a car lift, including a column, a housing, and a hydraulic pump. The hydraulic pump is installed inside the housing, and a column is located on the right side of the housing. Each column has a rotating shaft in its top inner cavity and a load-bearing plate in its inner cavity. A movable sling is connected to the front of each horizontal bar, and an alarm is installed at the top of each horizontal bar. An alarm flashing light is installed at the top of the alarm, and a fixing bolt is installed at the bottom of each movable sling. A ramp is connected to the front of each crossbar, and a main movable frame is installed on the back of each crossbar. A support platform is connected to the top of the main movable frame, and railings are installed on both sides of the top of the support platform. This invention provides a highly mobile, efficient, and safe vehicle suitable for widespread use.

[0004] Based on existing technology, it has been found that when the existing vehicle lifting displacement height measurement and positioning system is in use, the rubber block only makes initial anti-slip contact with the vehicle. It cannot firmly fix the rubber block after it deforms upon contact, and it cannot automatically strengthen the fixing effect. Furthermore, the existing vehicle lifting displacement height measurement and positioning system cannot move the protective mechanism during use, cannot provide auxiliary support and fixation when the vehicle slides and falls, cannot assist in protecting the staff, and lacks a secondary protective structure. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this device, an adjusting component is provided to adjust the angle, thereby contacting the anti-slip component with the bottom of the vehicle to assist in fixing and supporting the vehicle. When the anti-slip component contacts the bottom of the vehicle, it can be moved downward by the spring on the outer side of the bottom, so that the top of the anti-slip component can contact the car. At the same time, it can buffer the impact force generated during contact and avoid abnormal noise. When the adjusting component moves upward with the moving component, it can make the anti-slip component move downward, so that the moving block can move inside the anti-slip component. This allows for a stable contact with the vehicle through the contact block, so that the vehicle can be firmly fixed and the probability of the vehicle skidding and falling off can be reduced. In addition, when in use, the height of the moving block can be adjusted by the outer thread, so that the anti-slip component can be connected to the bottom of the vehicle when it is compressed to different degrees.

[0014] 2. This device includes a protective component installed at the bottom of the main body. When the device needs to provide secondary anti-slip fixation for the vehicle, the installation of the protective component can be controlled, allowing the force-bearing rod to be inserted into the auxiliary groove. Simultaneously, pulling the pull plate adjusts the position of the fixing block, allowing its top to be inserted into the pull groove, connecting the protective component to the moving component. When the moving component moves upward, it pulls the protective component upward. Simultaneously, the protective component is controlled by the top of the auxiliary groove, allowing it to move outward and adjust its height accordingly. Once the moving component is fixed, the protective component is also fixed inside the auxiliary groove. If the vehicle falls, it can contact the protective component and the auxiliary rod. The protective component is connected to the main body via the force-bearing rod, and the fixing block is connected to the moving component, allowing the protective component to simultaneously receive power from both the main body and the moving component to support the vehicle, making the vehicle more stable.

[0029] As attached Figure 1 To be continued Figure 8 As shown:

[0030] This invention provides an intelligent displacement height measurement and positioning system for car lifting, comprising a main body 1; the main body 1 is a car lift frame, and the main body 1 has an inverted U-shaped structure. A motor and a hydraulic cylinder are installed on the side of the main body 1. Two moving parts 2 are installed on both sides inside the main body 1. Protective parts 4 are installed on the inner side of the main body 1 and the inner side of the two moving parts 2. The moving parts 2 have a rectangular structure, and two rectangular plates are provided on the outer side of the moving parts 2. The bottom of the outer end of the moving parts 2 is connected to the piston rod through a connecting block. The moving parts 2 serve to receive the power of the piston rod to move up and down. Two adjusting parts 3 are installed on the moving parts 2 through a connecting part 201. The adjusting parts 3 include an anti-slip mechanism. The outer end of the adjusting parts 3 is equipped with an anti-slip mechanism. The adjusting parts 3 have a telescopic structure and serve to adjust the angle and position of contact with the vehicle, thereby stably supporting and fixing the vehicle. The protective parts 4 are composed of two rectangular structures. The bottom of the outer end and the top of the inner end of the protective parts 4 are inclined structures.

[0031] like Figure 2 As shown, the main body 1 further includes: a slot 101, which is rectangular in structure and symmetrically and evenly arranged on both sides of the main body 1. The slot 101 serves to allow the outer end of the limiting rod 205 to enter and exit, so that after the electric push rod 204 receives the signal from the PLC controller 103, it can fix the moving part 2; and an auxiliary slot 102, which is rectangular in structure and has an inclined outer top. The auxiliary slots 102 are evenly arranged on both ends of the inner side of the main body 1. 2. After the protective component 4 is subjected to force, the force-bearing rod 402 can be fixed, preventing the protective component 4 from moving downwards. When it moves upwards with the moving component 2, the top of the auxiliary groove 102 can control the protective component 4 to move outwards. PLC controller 103 has a data analysis module and a wireless transmission module installed inside. PLC controller 103 is electrically connected to the motor switch. PLC controller 103 is installed on the side of the main body 1. PLC controller 103 plays the role of controlling the operation of this device.

[0032] like Figure 5As shown, the movable component 2 includes: a connector 201, which has a U-shaped structure and two connecting shafts inside, and is fixed to the inner side of the movable component 2; a mounting groove 202, which has a rectangular structure and is located at the top center of the movable component 2; a photoelectric sensor 203, which is installed on both sides of the outer end of the movable component 2 and is electrically connected to the PLC controller 103. The photoelectric sensor 203 measures the height and transmits the signal to the PLC controller 103, enabling the PLC controller 103 to react and control the device; the movable component 2 also includes: an electric push rod 204, which is fixed inside the mounting groove 202. The electric push rod 204 is electrically connected to the PLC controller 103. The electric push rod 204 receives signals from the PLC controller 103, thereby allowing the limit rod 205 to be inserted into the slot 101 for fixation. The limit rod 205 is installed on the outer end of the electric push rod 204, and the outer end of the limit rod 205 is inserted into the slot 101. The moving part 2 also includes: a locking block 206, which is rectangular in structure and has an inclined bottom. The locking block 206 is fixed at the bottom center of the moving part 2 and connects to the fixed block 406 through the pull groove 207, allowing the fixed block 406 to be pulled. The pull groove 207 is rectangular in structure and is located on the inner side of the locking block 206.

[0033] like Figure 7As shown, the adjusting component 3 includes: a mounting component 301, the outer end of which is an annular structure, and the inner end of which is connected to the outer end of the adjusting component 3; an adjusting block 302, the middle of which is an annular structure, and the interior of which is threaded, with L-shaped structures on both sides, and fixed to the bottom of the outer end of the mounting component 301, the adjusting block 302 serves to install the moving block 303 via threads, allowing the moving block 303 to move up and down for adjustment, and then to contact and fix it to the vehicle via the contact block 304; a moving block 303, which is a cylindrical structure with a central protrusion, and is made of metal, with threads on its outer side, and is installed inside the adjusting block 302 via threads; and a contact block 304, which is a conical structure and is evenly arranged. The anti-slip mechanism includes: an anti-slip component 305, which has a cylindrical tubular structure in the middle and annular structures at both ends. The anti-slip component 305 is made of rubber and directly contacts the vehicle. The top of the anti-slip component 305 has annularly arranged conical holes. When the anti-slip component 305 contacts the bottom of the vehicle, it can be compressed, allowing air pressure to exist inside the conical holes, thus improving the cushioning effect. The middle part of the anti-slip component 305 is installed inside the outer end of the mounting component 301, and a spring is fitted on the outer side of the top of the anti-slip component 305. The side grooves 306 have an L-shaped structure, and two side grooves 306 are opened on both sides of the anti-slip component 305. The two sides of the adjusting block 302 are embedded inside the side grooves 306, which allow the adjusting block 302 to pass through on both sides.

[0034] like Figure 8As shown, the protective component 4 includes: auxiliary rods 401, which are rhomboid in shape, and four auxiliary rods 401 are fixed to both ends of the protective component 4. The auxiliary rods 401 serve to provide secondary support for the vehicle; and force-bearing rods 402, which are rectangular in shape and have a circular hole in the middle. Two rectangular slots are provided on both sides of the circular hole. The four force-bearing rods 402 are symmetrically fixed to both ends of the protective component 4. The force-bearing rods 402 are inserted into the auxiliary slots 102 and move within the auxiliary slots 102, allowing the protective component 4 to move upwards. The force-bearing rod 402 can slide inside the auxiliary groove 102. When the protective component 4 is under stress, it can be fixedly connected to the inside of the auxiliary groove 102 and will not move downward, thus providing stable support for the vehicle. The protective component 4 also includes a connecting plate 403, which is a rectangular structure. Two connecting plates 403 are installed at both ends inside the protective component 4. The connecting plates 403 serve to connect the protective component 4 through the guide block 404, so that when the protective component 4 moves upward, it can automatically move outward. After moving, it will then move inward again through the spring force on the outer side of the guide block 404, thereby allowing the force-bearing rod to move downward. 402 can be reinserted into the auxiliary slot 102; guide block 404, guide block 404 has a U-shaped structure and a round rod in the middle position of guide block 404, with a spring fitted on the outside of the round rod, two guide blocks 404 are installed on both sides of the connecting plate 403, the two ends of guide block 404 and the round rod are inserted into the round hole and rectangular slot of the force rod 402; slide 405, slide 405 has a T-shaped structure and a rectangular slot on the inner side of slide 405, slide 405 is opened at the top middle position of the connecting plate 403; the protective component 4 also includes: fixing block 406, fixing block 406 has an I-shaped structure The top two outer ends of the fixing block 406 are inclined. The top of the fixing block 406 is inserted into the groove 207. The bottom of the fixing block 406 is installed in the slide groove 405 by a spring. The fixing block 406 serves to connect with the groove 207, so that the protective part 4 can be connected to the moving part 2 at the same time, and thus receive the power support of the moving part 2 at the same time. The pull plate 407 has an L-shaped structure and is fixed to the inner end of the fixing block 406. The pull plate 407 is inserted into the rectangular groove of the slide groove 405. The pull plate 407 serves to control the guiding movement of the fixing block 406.

[0035] As another embodiment of the present invention, when it is necessary to repair the middle position of the bottom of the vehicle, the protective part 4 can be removed. First, the moving part 2 is raised, then the pull plate 407 is pulled, and then the protective part 4 is pulled to control the protective part 4 to be in an inclined state, thereby controlling the protective part 4 to be easily removed and avoiding affecting the vehicle being repaired.

[0036] In use: When this device is needed, the moving part 2 can be slightly raised manually, and then the protective part 4 can be pulled outward so that it can be installed at the bottom of the main body 1 in an inclined state. Then, the pulling plate 407 can be pulled so that the top of the fixing block 406 can be connected with the pulling groove 207. At the same time, the force rod 402 can be inserted into the auxiliary groove 102. Then, the moving part 2 can be lowered to the lowest position. When it is necessary to control the vehicle lifting, the adjusting part 3 can be rotated first so that the adjusting part 3 can drive the vehicle in. Then, the adjusting part 3 can be rotated so that the anti-slip part 305 can be in a proper position at the bottom of the vehicle. Then, the PLC controller 103 can be used to start the motor, drive the oil pump, draw pressurized oil from the oil tank into the oil cylinder, move the piston rod, and push the moving part 2 upward. When the moving part 2 moves upward, it contacts the bottom of the vehicle through the anti-slip part 305. After the anti-slip part 305 is pressed, the contact block 304 can be firmly fixed to the bottom of the vehicle. Then, the vehicle is lifted, and then the PLC controller 103 can be used to control the vehicle lifting. After the height is set and the movable part 2 moves to the appropriate height, the photoelectric sensor 203 transmits a signal to the PLC controller 103. The PLC controller 103 controls the electric push rod 204 to move, allowing the limit rod 205 to be inserted into the slot 101 for limiting and fixing. Simultaneously, as the movable part 2 moves upward, the fixing block 406 pulls the protective part 4 upward. When the protective part 4 moves upward, the force rod 402 contacts the top of the auxiliary slot 102, allowing the protective part 4 to move outward. When the protective part 4 is adjusted to the appropriate height... After the guide block 404 is tilted and falls, the spring on the outside of the round rod pushes the protective part 4 to reset, so that the force rod 402 can be re-embedded into the auxiliary groove 102. Then, when the vehicle is being repaired, the protective part 4 and the auxiliary rod 401 can help contact the bottom of the vehicle. The protective part 4 can receive force through the contact between the force rod 402 and the auxiliary groove 102, and at the same time, it can receive force through the connection between the fixing block 406 and the pull groove 207, so that the protective part 4 has stronger impact resistance and the vehicle can be more stably supported and fixed by the protective part 4.
