Description

Technical Field

[0001] This invention relates to the field of parking lot vehicle lifting technology, specifically to a vehicle lifting device that can prevent collisions. Background Technology

[0002] With social development and the improvement of people's living standards, motor vehicles have become the main means of transportation. The increasing number of vehicles has led to a shortage of parking spaces, so vehicle lifting equipment is usually installed in parking lots to accommodate more vehicles and meet social demand.

[0003] The existing authorized public account CN214835183U discloses a lifting system device for a three-dimensional parking garage, which includes a base plate. The side of the base plate is provided with a slide rail. The top surface of the base plate is provided with upwardly extending and parallel support columns. The top of the support column is movably sleeved with a sliding ring. The inner side of the sliding ring is fixedly connected to an upper frame. The frame is divided into upper and lower groups, and the lower frame is fixedly connected to the upper part of the base plate. The inner cavity of the frame is equipped with a fork. The top surface of the frame is fixedly connected with two sets of limiting seats. The front of the upper frame is fixedly connected with an inclined plate.

[0004] While the aforementioned lifting devices can meet the vehicle lifting requirements for use in parking lots, drivers may encounter several issues when reversing onto the lifting frame. Lack of skill or other factors could cause the vehicle to detach from the frame and collide with the lifting device. Furthermore, the absence of any protective structures around the vehicle when it is parked on the lifting device increases the risk of collisions due to driver error. Additionally, the lifting device cannot guarantee vehicle stability during lifting, leading to potential displacement and collisions. Therefore, under various circumstances and factors, vehicles are prone to colliding with the lifting device, resulting in damage to both the vehicle and the entire device, and compromising driver safety. In light of these issues, we propose a vehicle lifting device that prevents collisions. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a vehicle lifting device that can prevent collisions.

[0006] The technical solution of this invention is:

[0007] A vehicle lifting device to prevent collisions includes four symmetrically positioned support columns, with limit blocks fixedly installed at the front ends of the two front support columns. Lifting plates are slidably connected to the four support columns, and guardrails are fixedly installed on both sides of each lifting plate, with blocking blocks between the guardrails. The device also includes:

[0008] Collision protection component one, which is wrapped around the surface of the four support columns and is used for collision protection between the four support columns and the vehicle;

[0009] Second anti-collision component, which wraps around the surfaces of the two guardrails, is used for contact protection between the two guardrails and the vehicle;

[0010] A pushing component is disposed below the blocking block and connected to the lifting plate, which pushes the blocking block toward the rear of the vehicle along a direction parallel to the lifting plate;

[0011] A limiting component is provided in the middle of the lifting plate. It moves vertically and approaches the bottom of the vehicle to limit the lifting of the vehicle.

[0012] Preferably, a plurality of sliding grooves are provided at the connection between the four support columns and the anti-collision component, and a lifting component for driving the lifting plate to rise and fall is provided in the four support columns.

[0013] Preferably, a ramp is fixedly installed between the two limiting blocks.

[0014] Preferably, the anti-collision component one includes:

[0015] An airbag is provided on the outside of a support column, and a buffer pad is provided between the airbag and the support column. Several buffer components are provided between the buffer pad and the airbag at equal intervals.

[0016] Preferably, each of the buffer components includes:

[0017] Connecting post one, one side of which is fixedly connected to the outside of the buffer pad, and shock-absorbing spring one is fixedly connected to the other side of the connecting post one. Connecting post two is fixedly connected to the side of the shock-absorbing spring one away from connecting post one, and the side of the connecting post two away from the shock-absorbing spring one is fixedly connected to the inside of the airbag.

[0018] Preferably, a plurality of equally spaced buffer components are provided between the buffer pad and the support column.

[0019] Preferably, the second buffer component includes:

[0020] A sliding column is slidably connected to a groove on a support column. The outer side of the sliding column extends out of the groove and is fixedly connected to the inner side of a buffer pad. A second shock-absorbing spring is fixedly sleeved on the inner side of the sliding column, and the other end of the second shock-absorbing spring is fixedly connected to the inner wall of the groove.

[0021] Preferably, the structure of the second anti-collision component is the same as that of the first anti-collision component.

[0022] Preferably, the lifting plate is provided with a sliding groove, which is located on the rear side of the limiting component.

[0023] Preferably, the pushing component includes:

[0024] The slider has its upper end fixedly connected to the bottom of the blocking block, and its lower end slidably connected to the slide groove. A lead screw is threaded onto the slider, and the front and rear ends of the lead screw are rotatably connected to the front and rear sides of the slide groove, respectively. A first power source for driving the rotation of the lead screw is provided on one side of the lead screw.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In this invention, when a vehicle accidentally hits the two front support pillars, the speed of the vehicle can be slowed down by the two limiting blocks, and then the anti-collision component can be used to completely convert the kinetic energy generated by the vehicle into elastic potential energy, thereby improving the protection of the support pillars, the vehicle and the driver.

[0027] 2. In this invention, when a car accidentally deviates from the raised platform, it can be initially protected and blocked by the guardrails on both sides and the anti-collision component 2. At the same time, by pushing the component, the blocking block is moved to the rear of the vehicle's wheels, thereby further blocking the vehicle and achieving comprehensive protection of the vehicle, reducing losses.

[0028] 3. In this invention, when the car is being lifted, the limiting component firmly holds the vehicle to the lifting plate to ensure the stability of the vehicle during the lifting process, thereby preventing the vehicle from deviating and colliding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0042] Please see Figure 1-8 The present invention will describe the above technical solution in detail through the following embodiments:

[0043] A vehicle lifting device that prevents collisions includes four symmetrically positioned support columns 1. Limiting blocks 12 are fixedly installed at the front ends of the two front support columns 1. A ramp 11 is fixedly installed between the two limiting blocks 12. Several sliding grooves are provided at the connection between the four support columns 1 and the anti-collision component 13. Lifting components that drive the lifting plate 2 to rise and fall are provided inside the four support columns 1. The lifting plate 2 is slidably connected to the four support columns 1. Guardrails 21 are fixedly installed on both sides of the lifting plate 2. A blocking block 22 is provided between the two guardrails 21. A sliding groove 23 is provided on the lifting plate 2. The sliding groove 23 is located behind the limiting component 24.

[0044] In this embodiment, when a vehicle accidentally hits the two front support pillars 1, the two limiting blocks 12 set on the front can block the rear wheels of the car, reduce the speed of the car, thereby reducing the impact force between the car and the support pillars 1, and thus protect both the car and the support pillars 1. When the car accidentally deviates on the lifting plate 2, the guardrails 21 on both sides can effectively block the car and prevent the car from leaving the lifting plate 2 and hitting other vehicles.

[0045] The anti-collision component 13 is wrapped around the surface of the four support pillars 1 for collision protection between the four support pillars 1 and the vehicle. The anti-collision component 13 includes: an airbag 131, which is disposed on the outside of the support pillars 1, and a buffer pad 133 is disposed between the airbag 131 and the support pillars 1. Several buffer components 132 are disposed at equal intervals between the buffer pad 133 and the airbag 131. Each buffer component 132 includes: a connecting pillar 1321, one side of which is fixedly connected to the outside of the buffer pad 133, and the other side of which is fixedly connected to a shock absorber spring 1322. A connecting column 1323 is fixedly connected to the side of the connecting column 1322 away from the connecting column 1321. The side of the connecting column 1323 away from the shock-absorbing spring 1322 is fixedly connected to the inside of the airbag 131. Several buffer components 134 are provided between the buffer pad 133 and the support column 1. The buffer component 134 includes a sliding column 1341, which is slidably connected to the groove on the support column 1. The outer side of the sliding column 1341 extends out of the groove and is fixedly connected to the inside of the buffer pad 133. A shock-absorbing spring 1342 is fixedly sleeved on the inner side of the sliding column 1341. The other end of the shock-absorbing spring 1342 is fixedly connected to the inner wall of the groove.

[0046] In this embodiment, when the car collides with the support column 1, the car will exert a compressive force on the support column 1. At this time, the outer airbag 131 will first provide initial cushioning, and then, in conjunction with the rebound action of the shock absorber spring 1322, the impact force will be further reduced and dispersed to the buffer pad 133. The buffer pad 133 will further reduce and disperse the impact force. Finally, under the sliding buffering action of the sliding column 1341 and the second shock absorber spring 1342, the kinetic energy generated by the car will be completely converted into elastic potential energy, thereby effectively protecting the support column 1, the vehicle, and the driver, enhancing safety, and reducing vehicle damage.

[0047] The second anti-collision component is wrapped around the surface of the two guardrails 21 and is used for contact protection between the two guardrails 21 and the vehicle. The structure of the second anti-collision component is the same as that of the first anti-collision component 13.

[0048] In this embodiment, the protection principle of the second anti-collision component is the same as that of the first anti-collision component 13, which can effectively protect the guardrail 21, the vehicle, and the driver, enhance safety, and reduce vehicle damage.

[0049] A pushing component is located below the blocking block 22 and connected to the lifting plate 2. It pushes the blocking block 22 toward the rear of the vehicle along a direction parallel to the lifting plate 2. The pushing component includes a slider 222, the upper end of which is fixedly connected to the bottom of the blocking block 22, and the lower end of which is slidably connected to the slide groove 23. A lead screw 223 is threaded onto the slider 222. The front and rear ends of the lead screw 223 are rotatably connected to the front and rear sides of the slide groove 23, respectively. A first power source for driving the rotation of the lead screw 223 is provided on one side of the lead screw 223.

[0050] It should be noted that the first power source is a drive motor 221, which is fixedly installed on the rear side of the lifting plate 2. The output shaft of the drive motor 221 passes through the lifting plate 2 and extends into the slide groove 23. The extended end of the output shaft is fixedly connected to the lead screw 223.

[0051] In this embodiment, the drive motor 221 is started to drive the lead screw 223 to rotate, and the lead screw 223 will cause the slider 222 threadedly connected to it to move back and forth in the slide groove 23. At this time, the slider 222 will synchronously drive the blocking block 22 connected to it to move back and forth. Therefore, the blocking block 22 can be moved to the rear of the vehicle according to the size of the vehicle and the distance of the vehicle parking. Thus, the blocking block 22 can block the wheels of the parked vehicle, thereby preventing the rear of the vehicle from colliding and enhancing protection.

[0052] The limiting component 24 is located in the middle of the lifting plate 2. It moves vertically and approaches the bottom of the vehicle to limit the lifting of the vehicle.

[0053] It should also be noted that the limiting component 24 includes a mounting base 241, which is fixedly installed in the middle of the upper part of the lifting plate 2. An electric cylinder 242 is fixedly installed inside the mounting base 241. The piston rod of the electric cylinder 242 passes through the mounting base 241 and extends to the upper outer side of the mounting base 241. An electromagnetic chuck 243 is fixedly connected to the extended end of the piston rod.

[0054] In this embodiment, when the vehicle is parked on the lifting plate 2, the electric cylinder 242 can be activated to drive the electromagnetic chuck 243 connected to it to move up and down, so that the electromagnetic chuck 243 is attracted to the bottom of the vehicle and limited, thereby ensuring the stability of the vehicle during the lifting process, preventing the vehicle from deviating and colliding, and further improving the protection of the vehicle.

[0055] In practical use, when a vehicle accidentally hits the two front support pillars 1, the two limiting blocks 12 set on the front of the two support pillars 1 can block the rear wheels of the car, reduce the speed of the car, and thus reduce the impact force between the car and the support pillars 1. At the same time, the airbag 131 on the outside of the support pillar 1 will first provide initial buffering, and then, with the rebound action of the shock absorber spring 1322, the impact force will be reduced again and distributed to the buffer pad 133. The buffer pad 133 will further reduce and disperse the impact force. Finally, under the sliding buffering action of the sliding pillar 1341 and the second shock absorber spring 1342, the kinetic energy generated by the car is completely converted into elastic potential energy, thus effectively protecting the support pillars 1, the vehicle and the driver, enhancing safety and reducing vehicle damage.

[0056] Secondly, when the car drives onto the lifting plate 2, the anti-collision components on the guardrails 21 on both sides can also effectively protect the car. At the same time, by starting the drive motor 221, the lead screw 223 is driven to rotate. The lead screw 223 will cause the slider 222 connected to it to move back and forth in the slide groove 23. The slider 222 will synchronously drive the blocking block 22 connected to it to move back and forth. Therefore, according to the size of the vehicle and the distance of the vehicle parking, the blocking block 22 can be moved to the rear of the vehicle, thereby further blocking the wheels of the parked vehicle and preventing the rear of the vehicle from colliding.

[0057] Finally, when the vehicle is lifted using the lifting components, the electric cylinder 242 can be activated to drive the electromagnetic chuck 243 connected to it to perform lifting and lowering movements, so that the electromagnetic chuck 243 is attracted to the bottom of the vehicle and limited, thereby ensuring that the vehicle is stable on the lifting plate 2, preventing the vehicle from deviating and colliding, and further improving the protection of the vehicle.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
