[0002] In order to facilitate the maintenance of automobiles, the workstation configuration of repair shops has been gradually upgraded. In the earliest stage, repairmen inspected and repaired vehicle chassis and other components in the trench. Due to the depth and openness of the trench, vehicles and personnel often fell, causing economic losses and personal injuries. Then there was a ground-mounted gantry lift, which was used to lift the vehicle to facilitate the operation of the repairman. However, the columns of this lift were installed on the ground, which caused limitations. The car must be driven and parked away from the columns. The driver may accidentally hit the lift, and he must always pay attention to the door opening, which may hit the column, affecting the use of space. Later, there was an underground lift, which solved the workshop space problem. After the lift fell to the lowest position, only the swing arm part could be seen on the ground. The vehicle's driving space was improved and the door opening problem was solved, but the ground flatness was still a problem, and the wheel crushing problem was not completely solved.
[0003] Although the swing arm of the underground lift can be hidden by installing a cover, opening the cover is not an easy task and needs to be opened and closed manually. Due to the weight and height of the cover, the operator needs to bend over to operate it, which puts a heavy burden on the human body. Utility Model Content

[0034] The fully automatic cover plate of the underground swing arm lift provided by the utility model is specifically used in various links such as automobile maintenance, research and development, and production, so as to flexibly hide the lift under the ground and realize diversified use of the site.
[0035] Figure 1 to Figure 7 The fully automatic cover plate of the underground swing arm lift provided by one embodiment of the utility model includes a structural frame 1, a cover plate 2, a first flap 3, a second flap 4, a power assembly 5 and a control assembly 6; wherein:
[0036] The structural frame 1 is provided with a receiving groove for installing the lift 7; the volume of the receiving groove is sufficient to accommodate the lift 7, and the lift 7 is installed in the covered receiving groove; specifically, the structural frame is fixed in the foundation after being poured with cement; the overall structural frame adopts a metal structure, for example, the frame body is formed by bending and welding steel plates, and the receiving groove for accommodating the lift 7 is formed by the overall structural layout of the structural frame 1. The cover plate 2 can be opened and closed at the first covering area of the opening of the receiving groove, that is, the cover plate 2 can movably close or open the first covering area of the opening of the receiving groove, and the first covering area of the embodiment specifically covers most of the opening area of the receiving groove; in specific implementation, one edge of the cover plate 2 is connected to one edge of the opening of the receiving groove in a hinged manner, that is, the cover plate 2 is movably flipped with the hinged edge as the rotation axis to cover the first covering area of the opening of the receiving groove; and the cover plate 2 is transmission-connected with the power assembly 5 to switch the opening and closing state under the drive of the power assembly 5. The first flap 3 can be opened and closed and is arranged in the second covering area of the opening of the receiving slot, and the second covering area does not overlap with the first covering area; one edge of the first flap 3 is connected to the edge of the second covering area of the opening of the receiving slot in a hinged manner, so that the first flap 3 can be flipped around the hinged edge as a rotation axis, and the first flap 3 is transmission-connected to the power assembly 5 so as to switch the opening and closing state under the drive of the power assembly 5; the second flap 4 is rotatably assembled with the first flap 3, and is transmission-connected to the power assembly 5 so as to flip under the drive of the power assembly 5 The first flap 3 is in the covered state, and the second flap 4 can rotate relative to the first flap 3 to open and close the third covering area of the opening of the receiving slot. The third covering area is the lifting area of the lifting column 701 of the lift 7. The first covering area, the second covering area and the third covering area completely cover the opening area of the receiving slot. The control component 6 is electrically connected to the power component 5 to send a control instruction to the power component 5. The power component 5 is used to respond to the control instruction to output a driving force to drive the cover plate 2, the first flap 3 and the second flap 4 to move. Specifically, the third covering area is between the first covering area and the second covering area.
[0037] The first flap 3 and the second flap 4 of the present embodiment form a two-level flap structure. The second flap 4 is assembled on the first flap 3 and moves with the movement of the first flap 3. Therefore, when the first flap 3 is opened, the second flap 4 also flips accordingly. The second flap 4 can also flip relative to the first flap 3. Therefore, after the first flap 3 is opened, the second flap 4 can further flip relative to the first flap 3 to flip the second flap 4 from being parallel to the first flap 3 to being non-parallel. When the lift 7 hidden in the accommodating groove needs to be lifted, the cover plate 2 can be controlled to open first to expose the first covering area of most of the area of the accommodating groove, and then the first flap 3 can be controlled to open. In the process of the first flap 3 flipping, the second flap 4 is driven to leave the second covering area and the third covering area together, that is, all the covering areas of the accommodating groove opening are exposed at this time, and the lift 7 is lifted at this time. After the lift 7 is fully lifted, only a part of the area covered by the opening of the accommodating groove is occupied by the lifting column 701 of the lift 7 (that is, the third covering area). Figures 4-5 As shown; then, the second flap 4 is controlled to rotate to a predetermined position relative to the first flap 3, for example, to rotate to a relative angle of 0 degree, 90 degree or 360 degree with the first flap 3; preferably, in this embodiment, the size of the second flap 4 is not larger than the first flap 3, and the second flap 4 can be flipped and hidden under the first flap 3; that is, the second flap 4 is rotated to a relative angle of 360 degrees with the first flap 3, at which time the second flap 3 is fitted directly under the first flap 3; then the cover plate 2 is controlled to flip to the first covering area of the closing groove opening, and the first flap 3 is controlled to flip to the second covering area of the closing groove opening, and the second flap 4 is driven by the first flap 3 to be hidden under the second covering area, and the lift on the third covering area Column 701 is not affected, and the entire ground is completely flat; it does not affect the operation of the lift 7; when the lift 7 needs to be lowered back to the accommodating slot, the reverse operation is performed based on the above control logic, including first controlling the first flap 3 to open, controlling the cover 2 to open, and then controlling the second flap 4 to flip to be parallel to the first flap 3. After the lift 7 is lowered, the first flap 3 drives the second flap 4 to flip to cover the second covering area and the third covering area, and the cover 2 closes to cover the first covering area; when the hidden lift does not need to work, the lift 7 is completely sunk under the ground (cover), making the workshop floor barrier-free for driving and parking, making the floor tidy, and convenient for other activities, greatly saving space, and reducing the safety hazards of driving and pedestrians in the workshop. The above control logic is a preferred implementation method, and other control logics in the lifting process of the lift 7 based on the structural design of the cover 2, the first flap 3 and the second flap 4 can also be applied to this embodiment.
[0038] The installation height of the lift 7 is lowered to below the structural frame 1 (the swing arm can be hidden in the cover plate), the upper surface of the cover plate is flush with the ground, and the corresponding energy is supplied to the designated position according to the push rod power form. After the lift 7 is installed, the cover plate is installed and debugged.
[0039] In this embodiment, the upper surfaces of the cover plate 2 and the first flap 3 in the covered state are level with the ground, and the upper surface of the second flap 4 when covering the third covering area is level with the ground. That is, the entire structure is level with the ground in the covered state, keeping the working area flat.
[0040] Preferably, the structural frame 1, the cover plate 2, the first flap 3 and the second flap 4 are all metal structures.
[0041] The cover plate 2, the first flap 3 and the second flap 4 of this embodiment are all presented as a pair of left and right distributed structures, that is, they include a pair of left cover plates and right cover plates, a pair of left first flap plates and right first flap plates, a pair of left second flap plates and right second flap plates; and the left and right structures are symmetrical.
[0042] The power assembly of this embodiment includes a first transmission module 501, a second transmission module 502 and a third transmission module 503. The first transmission module 501 is connected to the cover plate 2 to drive the cover plate 2 to open and close, the second transmission module 502 is connected to the first flap 3 to drive the first flap 3 to open and close, and the third transmission module 503 is connected to the second flap 4 to drive the second flap 4 to flip relative to the first flap 3. Further, the first transmission module 501 is a pneumatic push rod, a hydraulic push rod or an electric push rod; and / or the second transmission module 502 is a pneumatic push rod, a hydraulic push rod or an electric push rod; and / or the third transmission module 503 is a pneumatic push rod, a hydraulic push rod or an electric push rod; high adaptability. That is, the cover plate 2, the first flap 3 and the second flap 4 can be powered by one of the optional pneumatic push rods / hydraulic push rods / electric push rods to replace manual operation. The operator only needs to generate control instructions through the control components to achieve automatic operation of the cover plate 2, the first flap 3 and the second flap 4, and people do not need to operate in the lift / vehicle area.
[0043] See also Figure 6 In this embodiment, the first transmission module 501 is a power push rod, one end of which is installed on the structural frame 1 through the first special-shaped structural member 511, and the other end is connected to the cover plate 2 through the second special-shaped structural member 512; the power push rod drives the cover plate 2 to perform the covering movement through the telescopic movement under the limiting action of the first special-shaped structural member 511 and the second special-shaped structural member 512.
[0044] See also Figure 7, a gear 611 is provided on the first flap 3, a connecting piece is provided on the second flap 4 and is assembled with the gear 611, the gear 611 is meshed and connected with a slide rack, the slide rack is composed of a slide 612 and a rack 613, the third transmission module 503 is connected with the slide rack to drive the slide rack transmission gear 611, and the gear 611 rotates to drive the second flap 4 to flip relative to the first flap 3. This structural design can effectively reduce the weight of the flap.
[0045] Furthermore, it also includes a sensor for detecting the lifting state of the lift 7, the sensor is connected to the control component 6 to send the sensing data to the control component 6, and the control component 6 outputs a control instruction according to the sensing data to achieve the activity interlock between the lift 7 and the power component 5. In specific implementation, if the lift 7 is detected to be active by the sensor, for example, the control component 6 outputs a corresponding stop operation instruction to control the power component 5 to work; conversely, only when the lift 7 is detected to be in a predetermined position by the sensor, the control component 6 outputs a corresponding control instruction to control the power component 5 to work, that is, the sensor data of the sensor is used in conjunction with the control instruction output of the control component 6 to achieve the activity interlock between the lift 7 and the power component 5, which has high safety; wherein, the sensor is preferably a position sensor.
[0046] The control component 6 can generate control instructions through user instructions received on the operation panel and send them to the power component 5 to drive related components to move; whether the cover and the lift are operable can be determined by the indicator lights on the operation panel.
[0047] In summary, the fully automatic cover of the underground swing arm lift provided by the utility model utilizes a two-level flap structure composed of a first flap and a second flap, which realizes the switching of the cover between a fully covered state and a lift use state, while avoiding interference with lift components; the modular structural design can be easily upgraded based on the manual operation of the cover; at the same time, the automatic control of the cover is interlocked with the lift, that is, the cover can be controlled to close only in a specific state of the lift, and the lift can be operated only in a specific state of the cover, thereby avoiding mutual collision and interference, and improving the safety of the equipment.
