As shown in fig. 1 and fig. 3, compared with the conventional floor spring structure, in this embodiment, the guiding protrusion 14 is attached to the bottom surface of the clip interface 11, the positioning protrusion 22 matched with the guiding protrusion 14 is disposed on the bottom surface of the steering wheel 21, the piston cylinder 1 and the spring are disposed on the mounting housing 4, the wheel shaft 2 is directly inserted into the clip interface 11, and then the clip interface 11 is packaged to position the wheel shaft 2, so that the mounting can be completed, the overall structure is simple, and the convenience of mounting and dismounting is greatly improved; meanwhile, two symmetrical positioning cambered surfaces 221 are arranged on the positioning convex block 22, a guiding tangent plane 141 matched with the positioning cambered surfaces 221 is arranged on the side surface of the guiding convex block 14, and the glass door is more stable and smooth in the opening and closing process through the radian buffering effect of the positioning cambered surfaces 221 and the guiding effect of the guiding tangent plane 141.

As shown in fig. 1 and 2, a slide rail 41, a first oil passage 42 and a second oil passage 43 are formed in the mounting housing 4, the piston cylinder 1 is mounted in the slide rail 41 and divides the slide rail 41 into a first oil chamber 411 and a second oil chamber 412, a third oil passage 44 and a fourth oil passage 45 for communicating the first oil chamber 411 and the second oil chamber 412 are formed between the first oil passage 42 and the second oil passage 43, a first oil hole 401 and a second oil hole 402 communicated with the first oil passage 42 are formed in the first oil chamber 411, a third oil hole 403 and a fourth oil hole 404 communicated with the second oil passage 43 are formed in the second oil chamber 412,

as shown in fig. 2, the right end of the first oil passage 42 is provided with a first oil regulating valve 5, the right end of the second oil passage 43 is provided with a second oil regulating valve 6, a first communicating channel 430 and a second communicating channel 431 are respectively provided between the first oil hole 401 and the second oil hole 402 and the second oil passage 43, the orifice of the first communicating channel 430 is provided with a third oil regulating valve 7, the orifice of the second communicating channel 431 is provided with a fourth oil regulating valve 8, and the fourth oil passage 45 is provided with a fifth oil regulating valve 9.

In the practical application process, when the glass door is opened, the spring 3 is extruded by the piston cylinder 1 in the directions of the first oil chamber 411 and the second oil chamber 412 under the driving of the wheel shaft 2, oil in the second oil chamber 412 enters the piston cylinder 1 through the oil outlet part 13 and enters the first oil chamber 411 through the one-way valve in the oil inlet part 12; however, when the door is opened too fast, the piston cylinder 1 in the floor spring moves toward the second oil chamber 412 and compresses the spring 3, and the spring 3 is compressed to generate a reaction force, so that when the door is opened suddenly by force, the glass door is often broken without the reaction of the oil and the spring 3. The fifth oil control valve 9 functions to allow oil in the second oil chamber 412 to flow from the fourth oil hole 404 to the second oil passage 43 through the fifth oil control valve 9 when the oil is compressed, and to drain oil from the first oil hole 401 and the second oil hole 402 back to the first oil chamber 411, thereby preventing the glass door from being broken by a large thrust force when the glass door is opened.

When the glass door is closed, because the spring in the second oil chamber 412 has already accumulated very large elastic potential energy, the piston cylinder 1 is driven to move integrally from the second oil chamber 412 to the first oil chamber 411 under the pushing of the spring. The oil in the first oil chamber 411 is pressurized and flows into the second oil passage 41 from the first oil hole 401 and the second oil hole 402. The larger the flow rate of the oil, the faster the door closing speed due to the addition of the return force of the spring, and therefore the higher the door closing speed, and when the piston cylinder 1 closes the second oil hole 402, the flow rate of the original first oil hole 401 and second oil hole 402 is changed to the flow rate of the first oil hole 401, and the speed at which the glass door closes is slowed down.

It should be noted that, when the glass door is blown by wind, the first oil regulating valve 5 plays a role of controlling the swing force of the glass door; the third oil control valve 7 is a relief oil control valve. In the actual installation, need through unscrewing second oil regulating valve 6 and the spring of the test of fourth oil regulating valve 8, when closing the glass door, the oil of first grease chamber 411 flows to second oil duct 43 from first oilhole 401 and second oilhole 402 easily in a large number, can lead to the door to strike fast to people's back brain or facial, causes personnel's injury, consequently can control the flow of living oil through third oil regulating valve 7, avoids the glass door to close excessively fast, has improved the security greatly.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
