Description

Technical Field

[0001] The utility model relates to the technical field of gas springs, in particular to a gas spring capable of outputting signals. Background Art

[0002] Gas spring is an industrial accessory that can support, buffer, brake, adjust height and adjust angle. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), cylinder control element and cylinder control element (referring to controllable gas spring) and joints. The principle is to fill the closed pressure cylinder with inert gas or oil-gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston to generate a pressure difference to achieve the movement of the piston rod. Due to the fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, small change in dynamic force (generally within 1:1.2), and easy control, but the general compression gas spring lacks warning after the car luggage compartment door is opened, and it is very dangerous to stop on the roadside to load and unload goods, so a more intelligent gas spring that increases personnel safety is proposed.

[0006] The technical effect achieved by adopting the above scheme is that by using this scheme, the sleeve and the piston rod can be fixedly connected to the automobile door by using a rotating connecting seat, and flexibility can be maintained.

[0007] Preferably, any of the above schemes has a mounting block fixedly connected to the inner wall of the circular mounting frame near the conductive plate, a spring fixedly connected to the bottom surface of the mounting block, the other end of the spring fixedly connected to one side of the conductive plate, and the side of the conductive plate away from the second conductive copper sheet is in contact with the piston rod.

[0008] The technical effect achieved by adopting the above scheme is: by using this scheme, the conductive plate can be pressed by a spring, one end of the conductive plate is fixedly connected to the second conductive copper sheet, and the other end can be pressed by the spring until it contacts the piston rod, which can reduce the wear and aging speed of the conductive plate, and increase the stability and tightness of the conductive plate when in contact with the piston rod, thereby preventing the current from being disconnected.

[0009] Preferably, according to any of the above schemes, the outer side of the conductive brush contacts the inner wall of the sleeve.

[0012] The technical effect achieved by adopting the above scheme is: by using this scheme, when one end of the conductive plate moves to one end of the insulating sleeve, the conductive plate can be guided to move above the piston rod, preventing the conductive plate from being blocked by the insulating sleeve and unable to move, thereby damaging the insulating sleeve and causing the current to be unable to be disconnected.

[0013] Preferably, in any of the above schemes, the second conductive copper sheet is in a circular ring shape, and a distance is left between the inner wall of the second conductive copper sheet and the piston rod.

[0014] The technical effect achieved by adopting the above solution is: by using this solution, the second conductive copper sheet can be prevented from being in contact with the piston rod at all times, resulting in the current being transmitted continuously without interruption.

[0015] The utility model has the following advantages:

At this time, the piston rod contacts the conductive plate and the second conductive copper sheet to form a passage state, so that the car's double flash lights can be turned on. The double flash lights can be turned on at the same time as the car's cargo door is opened, which serves as a warning. No manual operation is required, and the degree of automation is better.

[0017] 2. A gas spring that can output signals. When the piston rod is retracted into the sleeve, the conductive plate moves to one side of the insulating sleeve, and one end of the conductive plate can be extended to the outer wall of the insulating sleeve through the spring. At this time, there is an insulating sleeve between the conductive plate, the second conductive copper sheet and the piston rod, which can disconnect the current transmission between the conductive plate and the piston rod. When the car cargo door is closed, the double flash lights can be automatically turned off, further increasing the degree of automation and humanization. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0024] like Figures 1 to 4As shown, a gas spring capable of outputting a signal comprises a sleeve 1, a piston rod 6 is slidably connected inside the sleeve 1, one end of the piston rod 6 extends out of the sleeve 1, a first conductive copper sheet 2 is fixedly connected to an end of the outer wall of the sleeve 1 away from the piston rod 6, an insulating sleeve 5 is fixedly connected to an end of the outer wall of the sleeve 1 away from the first conductive copper sheet 2, one end of the insulating sleeve 5 is arranged around the outer wall of the piston rod 6 and is slidably connected to the outer wall of the piston rod 6, a piston 13 is fixedly connected to an end of the piston rod 6 located inside the sleeve 1, a conductive brush 12 is fixedly connected to a position of the piston rod 6 near the piston 13, a circular mounting frame 7 is fixedly connected to an end of the piston rod 6 away from the sleeve 1, an opening is left on one side of the circular mounting frame 7, and the opening faces the piston rod 6, a second conductive copper sheet 8 is fixedly connected to the inner wall of the circular mounting frame 7, and a conductive plate 11 is fixedly connected to a position of the second conductive copper sheet 8 near the piston rod 6.

[0025] As an optional technical solution of the present invention, the ends of the sleeve 1 and the piston rod 6 that are away from each other are fixedly connected with a rotating connecting seat 3. By using this solution, the sleeve 1 and the piston rod 1 can be fixedly connected to the automobile door using the rotating connecting seat 3, and flexibility can be maintained.

[0026] As an optional technical solution of the present utility model, a mounting block 10 is fixedly connected to the inner wall of the circular mounting frame 7 near the conductive plate 11, and a spring 9 is fixedly connected to the bottom surface of the mounting block 10. The other end of the spring 9 is fixedly connected to one side of the conductive plate 11, and the side of the conductive plate 11 away from the second conductive copper sheet 8 is in contact with the piston rod 6. By using this solution, the spring 9 can be used to press the conductive plate 11. One end of the conductive plate 11 is fixedly connected to the second conductive copper sheet 8, and the other end can be pressed by the spring 9 until it contacts the piston rod 6. The wear and aging speed of the conductive plate 11 can be reduced, and the stability and tightness of the conductive plate 11 when in contact with the piston rod 6 can be increased to prevent current disconnection.

[0027] As an optional technical solution of the present invention, the outer side of the conductive brush 12 is in contact with the inner wall of the sleeve 1. By using this solution, the conductive brush 12 can always contact the inner wall of the sleeve 1, thereby connecting the sleeve 1 and the piston rod 6. When current passes through the sleeve 1, the conductive brush 12 can be used to guide the current to the piston rod 6.

[0028] As an optional technical solution of the present invention, the end of the insulating sleeve 5 close to the piston rod 6 is provided with a chamfer, and the end of the conductive plate 11 close to the sleeve 1 is provided with a semicircular chamfer. By using this solution, when one end of the conductive plate 11 moves to one end of the insulating sleeve 5, the conductive plate 11 can be guided to move above the piston rod 6, thereby preventing the conductive plate 11 from being blocked by the insulating sleeve 5 and unable to move, thereby damaging the insulating sleeve 5 and causing the current to be unable to be disconnected.

[0029] As an optional technical solution of the present invention, the second conductive copper sheet 8 is in a circular ring shape, and a distance is left between the inner wall of the second conductive copper sheet 8 and the piston rod 6. By using this solution, the second conductive copper sheet 8 can be prevented from always contacting the piston rod 6, resulting in the current being transmitted continuously without interruption.

[0030] The following steps are required when using a gas spring that can output a signal:

[0031] 1) When the piston rod 6 extends out of the sleeve 1, the spring 9 drives one end of the conductive plate 11 to move until it contacts the outer wall of the piston rod 6. At this time, the current enters from the first conductive copper sheet 2;

[0032] 2) The conductive brush 12 plays a connecting role, guiding the current from the outer wall of the sleeve 1 to the piston rod 6. The piston rod 6 is now in contact with the conductive plate 11 and the second conductive copper sheet 8, thus forming a path state, so that the double flash lights of the car are turned on;

[0033] 3) There is an insulating sleeve 5 between the conductive plate 11 and the second conductive copper sheet 8 and the piston rod 6, which can cut off the current transmission between the conductive plate 11 and the piston rod 6.

[0034] To sum up, when the user uses it, the wires of the car double flash lights are connected to the first conductive copper sheet 2 and the second conductive copper sheet 8. When the piston rod 6 extends out of the sleeve 1, the spring 9 drives one end of the conductive plate 11 to move until it contacts the outer wall of the piston rod 6. At this time, the current enters from the first conductive copper sheet 2, and is conducted through the sleeve 1. The conductive brush 12 plays a connecting role, guiding the current from the outer wall of the sleeve 1 to the piston rod 6. At this time, the piston rod 6 contacts the conductive plate 11 and the second conductive copper sheet 8, and a passage state can be formed, so that the car double flash lights can be turned on, and the car cargo compartment can be opened. When the door is opened, the double flash lights are turned on to serve as a warning, and no human operation is required, with a better degree of automation. Finally, when the piston rod 6 is retracted into the sleeve 1, the conductive plate 11 moves to the side of the insulating sleeve 5, and one end of the conductive plate 11 can be extended to the outer wall of the insulating sleeve 5 through the spring 9. At this time, there is an insulating sleeve 5 between the conductive plate 11 and the second conductive copper sheet 8 and the piston rod 6, which can disconnect the current transmission between the conductive plate 11 and the piston rod 6, so that the double flash lights can be automatically turned off when the car cargo door is closed, further increasing the degree of automation and humanization.
