[0054] Example 1

[0055] Figure 1 1 shows a schematic diagram of the internal structure of the gas spring 100 in the first state provided in Example 1 of the present application. Figure 2 Schematic diagram of the internal structure of the gas spring 100 in the second state provided by Example 1 of the present application is shown. Figure 1 and Figure 2 Embodiment 1 of the present application provides a gas spring 100 .

[0056] The gas spring 100 includes a cylinder 110 , a piston rod 120 , a piston 130 , a stopper 140 and a regulating valve 150 .

[0057] The cylinder body 110 is provided with an oil chamber 111 and an air chamber 112 , and the oil chamber 111 and the air chamber 112 are separated by a floating piston 113 .

[0058] The piston 130 is slidably installed in the oil chamber 111 . The piston 130 and the piston rod 120 are connected via a regulating valve 150 . The regulating valve 150 can slide relative to the cylinder body 110 together with the piston 130 and the piston rod 120 .

[0059] In this embodiment, the piston 130 is connected to the regulating valve 150 through a gasket 131 and a nut 132. In other embodiments of the present application, the piston 130 may also be connected to the regulating valve 150 through other structures.

[0060] Figure 3 Shows Figure 1 Enlarged view of the middle part III; please refer to Figure 3 and Figure 1 In this embodiment, a sealing ring 152 is provided between the regulating valve 150 and the cylinder body 110 . The main function of the sealing ring 152 is to prevent the oil in the oil chamber from entering the gap between the regulating valve 150 and the wall of the cylinder body 110 .

[0061] The regulating valve 150 is connected to the piston rod 120 by riveting, and further, a sealing ring is provided at the connection position between the regulating valve 150 and the piston rod 120. A second cavity 101 is provided between the regulating valve 150 and the piston rod 120, and the second cavity 101 is used to contain hydraulic oil.

[0062] In this embodiment, the regulating valve 150 is provided with an oil conducting hole 151, which is mainly used to connect the second cavity 101 with the oil cavity 111. The oil conducting hole 151 passes through the regulating valve 150, and there is also a gap or hole between the piston 130 and the regulating valve 150, so that the oil conducting hole 151 connects the second cavity 101 with the oil cavity 111.

[0063] The limiter 140 is connected to the cylinder body 110 . The main function of the limiter 140 is that when the gas spring 100 is extended, the limiter 140 is used to abut against the regulating valve 150 to limit the further extension of the gas spring 100 .

[0064] In this embodiment, after the stopper 140 is assembled to the preset position, the relative position of the stopper 140 and the cylinder body 110 is limited by rolling the cylinder body 110 .

[0065] Please refer again Figure 1 In this embodiment, the piston rod 120 is provided with an ejector pin 121 and an adjusting member 122. The ejector pin 121 extends into the piston rod 120 and is slidably connected to the piston rod. The ejector pin 121 cooperates with the oil guide hole 151 to adjust the size of the oil guide hole 151.

[0066] The adjusting member 122 is slidably connected to the piston rod 120 and abuts against the ejector pin 121. The adjusting member 122 slides relative to the piston rod 120 to abut against the movement of the ejector pin 121. In detail, the positional relationship between the ejector pin 121 and the piston rod 120 is adjusted by the adjusting member 122. Under the action of the adjusting member 122, the ejector pin 121 slides relative to the piston rod 120 to block the opening of the oil guide hole 151, thereby adjusting the size of the oil guide hole 151.

[0067] Furthermore, the adjusting member 122 adjusts the size of the oil guide hole 151 through the ejector pin 121, thereby adjusting the cross-sectional flow rate of the oil flowing in the oil chamber 111, thereby adjusting the flow rate of the oil, and when the work done on the gas spring 100 is the same, the speed of contraction or extension of the gas spring 100 is adjusted. Thus, the speed of contraction of the gas spring 100 can be adjusted as needed.

[0068] In the embodiment of the present application, in order to reduce the processing and production costs of the ejector pin 121, the ejector pin 121 includes an ejector rod 123 and a valve needle 124. Both the ejector rod 123 and the valve needle 124 extend into the piston rod 120, the ejector rod 123 abuts against the valve needle 124, and the adjusting member 122 is used to abut against the ejector rod 123. The valve needle 124 cooperates with the oil guide hole 151, and a guide member 125 is provided on the outer sleeve of the valve needle 124, and the main function of the guide member 125 is to reduce the friction force during the relative sliding process between the valve needle 124 and the piston rod 120.

[0069] In this embodiment, the end of the valve needle 124 close to the oil conducting through hole 151 is conical, and is used to cooperate with the oil conducting through hole 151 to adjust the size of the oil conducting through hole 151 .

[0070] The second cavity 101 is formed by the valve needle 124 and the regulating valve 150 .

[0071] Furthermore, a first cavity 153 is provided between the regulating valve 150 and the cylinder body 110, and when the piston rod 120 slides relative to the cylinder body 110, the stopper 140 and the regulating valve 150 move relative to each other until the stopper 140 abuts against the regulating valve 150. In other words, the regulating valve 150, the stopper 140 and the cylinder body 110 are jointly enclosed to form the first cavity 153, and the stopper 140 and the regulating valve 150 move relative to each other, so that the size of the first cavity 153 is changed.

[0072] Hydraulic oil can be accommodated between the regulating valve 150 and the cylinder body 110. The limiter 140 is provided with an oil guide hole 141. The two ends of the oil guide hole 141 are respectively located on both sides of the limiter 140 along the length direction of the cylinder body 110. The main function of the oil guide hole 141 is to guide the hydraulic oil in the first cavity 153 to the outside of the first cavity 153 during the sliding of the piston rod 120 relative to the cylinder body 110, or to guide the hydraulic oil outside the first cavity 153 to the first cavity 153.

[0073] In the embodiment of the present application, the regulating valve 150 is provided with a flow hole 154, and the flow hole 154 communicates the second cavity 101 with the first cavity 153. The flow hole 154 penetrates the regulating valve 150, so that the flow hole 154 communicates with the first cavity 153 through the flow hole 154. In other words, the second cavity 101 communicates with the first cavity 153 through the flow hole 154, and the second cavity 101 is further communicated through the oil guide hole 151, so that the first cavity 153 communicates with the oil cavity 111.

[0074] In the present application, the regulating valve 150 is provided with one flow hole 154 . In other embodiments of the present application, the regulating valve 150 may be provided with a plurality of flow holes 154 . The present application does not limit the size, shape and dimensions of the flow hole 154 .

[0075] During the extension of the piston rod 120 relative to the cylinder body 110, the oil in the first cavity 153 is not only discharged through the oil guide hole 141, but also discharged through the flow hole 154. Accordingly, during the compression of the piston rod 120 relative to the cylinder body 110, the oil enters the first cavity 153 through the flow hole 154 and the oil guide hole 141 at the same time, so as to increase the compression or extension speed of the piston rod 120 relative to the cylinder body 110.

[0076] It should be noted that in other embodiments of the present application, the piston rod 120 may not be provided with the ejector pin 121 and the regulating member 122, and accordingly, the regulating valve 150 may not be provided with the oil guide hole 151. For example, the piston rod 120 is connected to the regulating valve 150, the piston 130 is connected to the regulating valve 150, and the piston 130 and the regulating valve 150 are provided with holes to connect the cavities on both sides of the piston 130. Accordingly, the regulating valve 150 is provided with a flow hole 154, and the flow hole 154 connects the oil chamber 111 with the first cavity 153. In other words, for an embodiment in which there is no second cavity 101 between the piston rod 120 and the regulating valve 150, the flow hole 154 is directly connected to the oil chamber 111; or, for an embodiment in which the piston rod 120 and the regulating valve 150 are not connected to the second cavity 101, the flow hole 154 is directly connected to the oil chamber 111. The oil in the oil chamber 111 can be introduced into or out of the first chamber 153 through the flow hole 154 , thereby accelerating the compression or extension of the piston rod 120 relative to the cylinder body 110 .

[0077] The gas spring 100 provided in Embodiment 1 of the present application has at least the following advantages:

[0078] By setting the flow hole 154, the oil in the first cavity 153 can be discharged or introduced faster, thereby increasing the speed of stretching and compressing the gas spring 100. The setting of the adjustment member 122 and the ejector pin 121 can further adjust the size of the oil guide hole 151, thereby adjusting the cross-sectional flow rate of the oil flowing in the cavities on both sides of the piston 130, thereby adjusting the flow rate of the oil. Under the condition of the same work done on the gas spring 100, the speed of contraction or extension of the gas spring 100 can be adjusted by the adjustment member 122. Thus, the speed of contraction of the gas spring 100 can be adjusted as needed.

[0079] As an example, when the gas spring 100 is installed in a unit door scenario, the speed of opening and closing the door can be adjusted as needed.

[0080] Example 2

[0081] Figure 4 The structure diagram of the gas spring assembly 200 provided in the second embodiment of the present application from a first viewing angle is shown. Figure 5 FIG. 2 is a schematic diagram showing a gas spring assembly 200 from a second perspective provided in Example 2 of the present application. Figure 4 and Figure 5 Embodiment 2 of the present application provides a gas spring assembly 200 , and the gas spring assembly 200 includes a rotating arm 210 and a gas spring 220 .

[0082] The rotating arm 210 has a first end 211 and a second end 212 opposite to each other. The second end 212 is provided with a strip hole 213. The strip hole 213 extends from the first end 211 to the second end 212. In other words, the length direction of the strip hole 213 is from the first end 211 to the second end 212.

[0083] One end of the gas spring 220 is rotatably connected to the first end 211. One end of the gas spring 220 may be one end of the cylinder 221, or may be one end of a piston rod.

[0084] In the embodiment of the present application, the free end of the cylinder 221 of the gas spring 220 is rotatably connected to the first end 211 .

[0085] The free end of the cylinder body 221 refers to the end of the cylinder body 221 away from the piston rod. The free end is relative to the piston rod and refers to the free end before being connected to the first end 211, not after being connected to the first end 211.

[0086] The first end 211 of the rotating arm 210 is rotatably connected to the cylinder body 221 so that the two can rotate relative to each other. The second end 212 is provided with a strip hole 213. After the strip hole 213 is connected to a component (such as a door), the force of the component is transmitted to the rotating arm 210 through the second end 212, so that the rotating arm 210 rotates like the gas spring 220 while stretching or compressing the gas spring 220. The component and the rotating arm 210 are reset under the action of the gas spring 220. By providing the rotating arm 210 and the strip hole 213, the installation cost of the gas spring 220 is reduced, the gas spring 220 is easy to install, and the strip hole 213 can simplify the debugging process of the gas spring 220.

[0087] In the embodiment of the present application, the structure of the gas spring 220 is the same as that of the gas spring 100 in Embodiment 1, so it will not be described in detail in the present application. The first end 211 is rotatably connected to the end of the cylinder body 110 of the gas spring 100 away from the piston rod 120 .

[0088] It should be noted that in other embodiments of the present application, the gas spring 220 may also adopt other structures, such as a commercially available gas spring 220 in the prior art.

[0089] The following description is made by taking the gas spring 100 as an example.

[0090] As mentioned above, the first end 211 of the rotating arm 210 is rotatably connected to the gas spring 100. The second end 212 is provided with a strip hole 213; in this embodiment, the rotating arm 210 has a receiving cavity 203, and the receiving cavity 203 is used to accommodate the gas spring 100. After the rotating arm 210 rotates relative to the gas spring 100, the gas spring 100 can be accommodated in the receiving cavity 203 of the rotating arm 210, so that the gas spring 100 cannot be seen from the appearance, thereby increasing the aesthetics of the gas spring assembly 200.

[0091] It should be noted that in other embodiments of the present application, the rotating arm 210 may also be in other shapes, for example, it may be a long thin plate, which can rotate relative to the gas spring 100 so that the long thin plate can overlap with the gas spring 100.

[0092] Figure 6 Shows Figure 4 For the enlarged view of the middle VI, please refer to Figure 6 In an embodiment of the present application, the gas spring assembly 200 also includes a base 230, the base 230 is equipped with a rotating shaft 231, the first end 211 of the rotating arm 210 is rotatably connected to the rotating shaft 231, the first end 211 of the rotating arm 210 is equipped with a mounting shaft 232, and the mounting shaft 232 is rotatably connected to the free end of the cylinder body 110.

[0093] In other words, the rotating arm 210 is rotatably connected to the base 230 via the rotating shaft 231 ; so that the rotating arm 210 can rotate relative to the base 230 , the rotating arm 210 is rotatably connected to the free end of the cylinder body 110 via the mounting shaft 232 .

[0094] The base 230 can constrain the relative position of the connection position of the rotating arm 210 and the cylinder body 110 to prevent the two from moving during the rotation process. In the present application, the piston rod 120 of the gas spring 100 is fixedly connected to the base 230. During the rotation of the rotating arm 210 relative to the gas spring 100, one end of the piston rod 120 is fixed relative to the base 230, and the cylinder body 110 is compressed or extended relative to the piston rod 120.

[0095] Furthermore, in this embodiment, the mounting shaft 232 is rotatably connected to the fixing plate 233 , and the free end of the cylinder body 110 is connected to the fixing plate 233 .

[0096] The rotating arm 210 rotates relative to the rotating shaft 231 , thereby driving the mounting shaft 232 to rotate, and the fixing plate 233 drives the cylinder body 110 to be compressed or extended relative to the piston rod 120 .

[0097] It should be noted that, in other embodiments of the present application, the first end 211 of the rotating arm 210 may be rotatably connected to the cylinder body 110 in other ways.

[0098] For example, in some other embodiments of the present application, the gas spring assembly 200 may not include the base 230. For example, the cylinder body 110 is directly connected to a door frame or other components, and the free end of the cylinder body 110 is rotatably connected to the first end 211 of the rotating arm 210. Further, the free end of the cylinder body 110 is hinged to the first end 211, and the first end 211 of the rotating arm 210 is rotatably connected to a door frame or other components, so that the rotating arm 210 rotates relative to the cylinder body 110 and the gas spring 100 can be stretched or compressed.

[0099] In this embodiment, in order to limit the maximum rotation angle of the rotating arm 210 and the cylinder body 110, the gas spring assembly 200 also includes a limiter 240, which is installed on the side of the second end 212 away from the cylinder body 110. The limiter 240 is used to limit the rotation angle of the rotating arm 210 relative to the gas spring 100.

[0100] In other words, the stopper 240 and the cylinder body 110 are respectively located on both sides of the rotating arm 210 . After the rotating arm 210 rotates relative to the gas spring 100 , the rotating arm 210 can abut against the stopper 240 to prevent the rotating arm 210 from further rotating.

[0101] In this embodiment, the limiting member 240 is installed on the base 230. The limiting member 240 is cylindrical, and the limiting member 240 is arranged parallel to the installation axis 232.

[0102] It should be noted that, in other embodiments of the present application, the stopper 240 may be provided separately, for example, installed on a component connected to the gas spring assembly 200; accordingly, the stopper 240 may be in the shape of a protrusion, a separately provided frustum, etc. In addition, in other embodiments of the present application, the stopper 240 may not be provided according to the usage scenario of the gas spring assembly 200.

[0103] In the embodiment where the gas spring assembly 200 is installed on a revolving door, the setting of the limit member 240 can limit the maximum opening of the revolving door. In this embodiment, after the limit member 240 is set, the maximum angle between the gas spring 100 and the rotating arm 210 is controlled to be 110°. In other embodiments of the present application, the maximum angle between the gas spring 100 and the rotating arm 210 can be 100°, 120°, 115°, etc.

[0104] As mentioned above, the piston rod 120 of the gas spring 100 is fixedly connected to the base 230. Please refer to Figure 1 and Figure 6 In this embodiment, the end of the piston rod 120 is connected to the base 230 through a fixed bracket 201.

[0105] Please refer to the first embodiment again, the adjusting member is slidably connected to the piston rod 120 and abuts against the ejector pin 121. The adjusting member 122 slides relative to the piston rod 120 to abut against the ejector pin 121 to move.

[0106] The piston rod 120 is provided with a mounting hole 202, and the fixing bracket 201 is connected to the mounting hole 202 through a fixing shaft, so that the piston rod 120 is fixed to the base 230. The fixing shaft extends into the mounting hole 202, but the fixing shaft does not limit the movement of the adjusting member 122 relative to the piston rod 120.

[0107] It should be noted that, in the embodiment of the gas spring 100 without the adjusting member 122 , the base 230 may be directly fixedly connected to the piston rod 120 by means of bolts or the like.

[0108] The main advantages of the gas spring assembly 200 provided in the embodiment of the present application are:

[0109] By setting the rotating arm 210 and the strip hole 213, during the installation process, the movable parts and other components can be inserted into the strip hole 213, thereby reducing the installation cost of the gas spring 220, making the gas spring 220 easy to install, and the strip hole 213 can simplify the debugging process of the gas spring 220.

[0110] In addition, the gas spring assembly 200 also has the advantages of the gas spring 100. The same force acts on the rotating arm 210, and the gas spring 100 can be retracted and retracted faster, so that the rotating arm 210 can rotate faster relative to the gas spring 100, and can be opened and reset quickly.

[0111] It should be noted that in the embodiments of the present application, the usage scenario of the gas spring assembly 200 is not limited.
