Description

Technical Field

[0001] The invention belongs to the technical field of anti-slip protection, and in particular relates to an anti-slip protection device for parking equipment. Background Art

[0002] With the development of science and technology, existing parking lots are usually equipped with parking equipment, which is convenient for raising the car to the second floor when the parking spaces are insufficient, thereby saving land while meeting the demand for parking spaces. In the process of the parking equipment raising the vehicle, an anti-fall protection device needs to be set to protect the vehicle and prevent the vehicle from tilting and falling.

[0003] The existing anti-slip protection device often has the following technical problems when protecting the vehicle:

[0004] 1. During use, since the load-bearing plate of the car needs to be reset by a spring, the load-bearing plate will tilt after long-term use due to the reduction of the elastic force of the spring, and the existing protection device cannot reset the car, causing the car to tilt along with the load-bearing plate, and then the car may slide off the load-bearing plate, which has a poor anti-fall protection effect on the car;

[0005] 2. When the load plate and the car are tilted, the wheels cannot be locked automatically, which may cause the wheels to drive the car to move on the load plate, further reducing the protection effect of the car;

[0006] 3. When the load-bearing plate causes the car to tilt, it is impossible to warn the management personnel in time, resulting in the management personnel being unable to take timely remedial measures, which increases the possibility of the car falling off the load-bearing plate. Summary of the invention

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An anti-drop protection device for parking equipment, comprising:

[0010] A load-bearing plate and a support plate, wherein two arc-shaped clamping plates are fixedly connected to the lower part of the load-bearing plate, and two mounting seats are fixedly connected to the upper part of the support plate.

[0012] Two locking assemblies, each of the locking assemblies comprises a battery, two clamping grooves, two clamping plates, two liquid pumping chambers, two pistons, two electromagnets, wires, two magnets, two first springs and two C-shaped connecting rods, the battery is fixedly connected to the inside of the carrying plate, the two clamping grooves are respectively opened at the top of the two lifting frames, the two clamping plates are respectively sealed and slidably connected to the inner walls of the two clamping grooves, the two liquid pumping chambers are respectively opened at the bottom of the two clamping grooves, the two pistons are respectively sealed and slidably connected to the inner walls of the two liquid pumping chambers, the two electromagnets are fixedly connected to the outer wall of the two clamping grooves on one side close to the battery, the two electromagnets are electrically connected to the battery through wires, the two magnets are respectively slidably connected to the bottom of the two liquid pumping chambers, the two magnets are respectively elastically connected to the inner wall of the lifting frame through two first springs, and the two magnets are fixedly connected to the two pistons through C-shaped connecting rods.

[0013] Preferably, it also includes: a warning component, which includes a circular guide cavity, a rotating shaft, three impact plates, three arc-shaped rotating plates, three first conductive sheets, a second conductive sheet and a warning light, the circular guide cavity is opened in the middle position of the connecting cavity, the rotating shaft is rotatably connected to the inside of the circular guide cavity, the three impact plates are fixedly connected to the rotating shaft, the three arc-shaped rotating plates are respectively fixedly connected to the three impact plates, the three first conductive sheets are respectively fixedly connected to the three arc-shaped rotating plates, the second conductive sheet is fixedly connected to the inner wall of the circular guide cavity, and a warning light is fixedly connected to the support plate, and when any of the three first conductive sheets contacts the second conductive sheet, the warning light is energized and works.

[0014] Preferably, a third conductive sheet is fixedly connected to the side walls of the two arc-shaped clamping plates, and a fourth conductive sheet is disposed on the inner walls of the two arc-shaped clamping slots.

[0015] Preferably, when the two third conductive sheets are in contact with the two fourth conductive sheets, the battery energizes the two electromagnets.

[0023] 3. The present invention provides a warning component. When the bearing plate is tilted and the magnetorheological fluid flows, the impact plate can be driven to rotate by the flow of the liquid, so that the three first conductive plates are intermittently in contact with the second conductive plates, and the warning light flashes intermittently, so as to promptly warn the management personnel and enable the management personnel to take remedial measures in time when the bearing plate is tilted, thereby reducing the possibility of the car falling from the bearing plate and being damaged.

DETAILED DESCRIPTION

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0032] like Figure 1-Figure 6 As shown, an anti-slip protection device for parking equipment includes:

[0033] The load-bearing plate 1 and the support plate 2, the lower part of the load-bearing plate 1 is fixedly connected with two arc-shaped clamping plates 11, the upper part of the support plate 2 is fixedly connected with two mounting seats 21, the upper parts of the two mounting seats 21 are provided with two arc-shaped clamping grooves 22, and the two arc-shaped clamping plates 11 are respectively matched with the two arc-shaped clamping grooves 22;

[0034] Among them, the side walls of the two arc-shaped card plates 11 are fixedly connected with a third conductive sheet 111, and the inner walls of the two arc-shaped card slots 22 are provided with a fourth conductive sheet 112. When the two third conductive sheets 111 are in contact with the two fourth conductive sheets 112, the battery 41 energizes the two electromagnets 46. Only when the supporting plate 1 is in a horizontal position, the two third conductive sheets 111 are in contact with the two fourth conductive sheets 112 at the same time, and the battery 41 can energize the electromagnet 46 and the wire 47 at this time. When the supporting plate 1 is tilted in any direction, the two third conductive sheets 111 are no longer in contact with the two fourth conductive sheets 112, and the battery 41 will no longer energize the electromagnet 46 and the wire 47.

[0035] The two arc-shaped clamping plates 11 are elastically connected to the inner walls of the two arc-shaped clamping grooves 22 through two second springs 113 respectively. The elastic force of the two second springs 113 can reset the load-bearing plate 1 to prevent the load-bearing plate 1 from causing the car to tilt.

[0036] Two anti-tilt components 3, each anti-tilt component 3 includes two top grooves 31, two lifting frames 32 and a connecting cavity 33, the two top grooves 31 are both opened at the top of the bearing plate 1, the two lifting frames 32 are respectively slidably connected to the inner walls of the two top grooves 31, the connecting cavity 33 is opened inside the bearing plate 1 and communicated with the bottoms of the two top grooves 31, and a magnetorheological fluid is arranged between the two top grooves 31 and the connecting cavity 33. The magnetorheological fluid is a suspension formed by ferromagnetic particles of micrometer or nanometer size immersed in a non-magnetic carrier liquid, exhibits low-viscosity Newtonian fluid characteristics when there is no external magnetic field, and exhibits high-viscosity, low-fluidity Bingham fluid when an external magnetic field is applied;

[0037] It is worth mentioning that when the supporting plate 1 is tilted, the two third conductive sheets 111 and the two fourth conductive sheets 112 are no longer in contact with each other. At this time, the battery 41 no longer supplies power to the wire 47, and no magnetic field is generated around the wire 47. The fluidity of the magnetorheological fluid is enhanced, so that the magnetorheological fluid in the top groove 31 on the higher side flows to the top groove 31 on the lower side under the action of gravity, so that the two lifting frames 32 are always at the same height, and then the two sides of the car are at the same height, which can reset the car to prevent the car from tilting and sliding off the supporting plate 1, thereby improving the anti-slip protection effect of the car.

[0038] Two locking assemblies 4, each locking assembly 4 includes a battery 41, two clamping grooves 42, two clamping plates 43, two pumping chambers 44, two pistons 45, two electromagnets 46, a wire 47, two magnets 48, two first springs 49 and two C-shaped connecting rods 410, the battery 41 is fixedly connected to the inside of the carrier plate 1, the two clamping grooves 42 are respectively opened at the top of the two lifting frames 32, the two clamping plates 43 are respectively sealed and slidably connected to the inner walls of the two clamping grooves 42, the two pumping chambers 44 are respectively opened at the two clamping grooves 42, and the two pumping chambers 44 are respectively opened at the two clamping grooves 42. At the bottom of the tightening groove 42, two pistons 45 are respectively sealed and slidably connected to the inner walls of the two pumping chambers 44, two electromagnets 46 are fixedly connected to the outer walls of the two clamping grooves 42 on one side close to the battery 41, the two electromagnets 46 are electrically connected to the battery 41 through a wire 47, two magnets 48 are respectively slidably connected to the bottom of the two pumping chambers 44, the two magnets 48 are respectively elastically connected to the inner wall of the lifting frame 32 through two first springs 49, and the two magnets 48 are fixedly connected to the two pistons 45 through a C-shaped connecting rod 410.

[0039] Among them, hydraulic oil is provided inside each clamping groove 42, so that when the hydraulic oil enters the pumping chamber 44, the clamping plate 43 can move downward in the clamping groove 42, and when the hydraulic oil is completely in the clamping groove 42, the clamping plate 43 can move up to the top of the clamping groove 42, so that the wheel will not be stuck in the clamping groove 42.

[0040] The wire 47 is close to the two top grooves 31 and the bottom of the connecting cavity 33 , so that when the wire 47 is energized, the fluidity of the magnetorheological fluid in the top groove 31 and the connecting cavity 33 can be reduced under the action of the magnetic field.

[0041] When the electromagnet 46 is energized to generate magnetism, a magnetic attraction force is generated between the corresponding magnets 48 , and the magnetic attraction force between the electromagnet 46 and the magnet 48 can overcome the elastic force of the first spring 49 .

[0042] It should be noted that when the supporting plate 1 is tilted and the battery 41 no longer supplies power to the wire 47, the electromagnet 46 can be de-energized, so that no magnetic attraction is generated between the electromagnet 46 and the magnet 48, and the magnet 48 slides due to the elastic force of the first spring 49, and the piston 45 is further driven to move in the pumping chamber 44 through the C-shaped connecting rod 410, so that the hydraulic oil in the clamping groove 42 is sucked into the inside of the pumping chamber 44, so that the clamping plate 43 moves downward, so that the wheel can sink into the clamping groove 42, and the wheel is locked, which further improves the protection effect of the car.

[0043] The warning component 5 includes a circular guide cavity 51, a rotating shaft 52, three impact plates 53, three arc-shaped rotating plates 54, three first conductive sheets 55, a second conductive sheet 56 and a warning light 57. The circular guide cavity 51 is opened in the middle position of the connecting cavity 33. The rotating shaft 52 is rotatably connected to the inside of the circular guide cavity 51. The three impact plates 53 are fixedly connected to the rotating shaft 52. The three arc-shaped rotating plates 54 are respectively fixedly connected to the three impact plates 53. The three first conductive sheets 55 are respectively fixedly connected to the three arc-shaped rotating plates 54. The second conductive sheet 56 is fixedly connected to the inner wall of the circular guide cavity 51. A warning light 57 is fixedly connected to the support plate 2. When any of the three first conductive sheets 55 contacts the second conductive sheet 56, the warning light 57 is energized and works.

[0044] It should also be noted that when the supporting plate 1 is tilted and the magnetorheological fluid flows, the flow of the liquid can drive the impact plate 53 to rotate, thereby causing the three arc-shaped rotating plates 54 to rotate, and the three first conductive plates 55 intermittently contact the second conductive plates 56, causing the warning light 57 to flash intermittently, thereby promptly warning the management personnel, so that the management personnel can take remedial measures in time when the supporting plate 1 is tilted, thereby reducing the possibility of the car falling from the supporting plate 1 and being damaged. A buzzer alarm can also be set to further warn the management personnel.

[0045] The present invention can be explained by the following operation mode:

[0046] S1: When the car is parked, the car is driven on the carrier plate 1 so that the four wheels of the car are on the four clamping plates 43. When the carrier plate 1 is not tilted, the third conductive sheet 111 is in contact with the fourth conductive sheet 112. At this time, the battery 41 energizes the electromagnet 46 and the wire 47. The magnetic field around the wire 47 makes the fluidity of the magnetorheological fluid very low. At the same time, the magnetic attraction between the electromagnet 46 and the magnet 48 makes the hydraulic oil all in the clamping groove 42. At this time, the clamping plate 43 is at the top, and the wheel will not fall into the clamping groove 42, which will not hinder the car from driving out;

[0047] S2: After being used on the bearing plate 1 for a period of time, the elastic force of the second spring 113 decreases, and the bearing plate 1 is in a tilted state. The third conductive sheet 111 is no longer in contact with the fourth conductive sheet 112, and the battery 41 is no longer powered, and a magnetic field is no longer generated around the wire 47. The fluidity of the magnetorheological fluid decreases. Under the action of gravity, the magnetorheological fluid in the higher top groove 31 will flow through the connecting cavity 33 to the lower top groove 31, so that the lifting frame 32 in the lower top groove 31 moves upward, and the lifting frame 32 in the higher top groove 31 moves downward, so that the two sides of the car are at the same height, and the car is reset to prevent the car from tilting;

[0048] S3: At the same time, the electromagnet 46 is no longer energized, and the magnet 48 moves under the elastic force of the first spring 49, driving the piston 45 to move in the pumping chamber 44 through the C-shaped connecting rod 410, so that the hydraulic oil in the clamping groove 42 is sucked into the inside of the pumping chamber 44, so that the clamping plate 43 moves downward, so that the wheel can fall into the clamping groove 42, and the wheel is locked;

[0049] S4: In addition, when the supporting plate 1 tilts and causes the magnetorheological fluid to flow, the flow of the liquid can drive the impact plate 53 to rotate, so that the three first conductive plates 55 intermittently contact the second conductive plates 56, and the warning light 57 flashes intermittently, so as to promptly warn the management personnel and enable the management personnel to take remedial measures in time when the supporting plate 1 tilts.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
