Description

Technical Field

[0001] The utility model relates to the technical field of inflation equipment, in particular to a shock absorber inflation device. Background Art

[0002] Automobiles are typically equipped with shock-absorbing springs. These absorb road vibrations when driving over uneven surfaces, but the springs themselves also experience reciprocating motion. To prevent spring bounce, cars are also equipped with shock absorbers. These dampen the vibrations caused by the springs rebounding after absorbing the shock, as well as the impact from the road surface. This accelerates the attenuation of frame and body vibrations, thereby improving the vehicle's ride comfort. Shock absorbers primarily utilize the flow of oil between the piston and cylinder to generate damping, converting vibration energy into heat and thus providing shock absorption. However, during shock absorber operation, the oil can foam, leading to lost motion and discontinuities in resistance, which in turn affects the damping effect. To address this issue, existing technologies employ low-pressure nitrogen gas injection into the shock absorber to eliminate oil foaming, thereby eliminating lost motion and discontinuities in resistance and improving the damping effect.

[0003] However, in the prior art, the shock absorber is generally inflated manually, but manual inflation is inefficient, and the inflation effect cannot be known after inflation, and the shock absorber is easily damaged. Utility Model Content

[0004] The purpose of the utility model is to provide a shock absorber inflation device to solve the problems of low manual inflation efficiency, inability to know the inflation effect after inflation, and easy damage to the shock absorber.

The shock absorber inflation device also includes a second driving member, which is configured to drive the air-breaking head to move along the first direction and insert the plug between the oil seal and the piston rod.

[0012] Preferably, the air-breaking head is located between the first sealing ring and the second sealing ring, and the thickness of the plug gradually decreases from the side away from the second sealing ring to the side close to the second sealing ring.

[0021] Beneficial effects of the utility model:

[0022] The utility model forms a sealed inflation chamber on the outer periphery of the shock absorber through the inflation platform, and forms a gap for subsequently establishing a gas channel between the oil seal and the piston rod of the shock absorber through the breaker head.

[0041] In order to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road, the car is generally equipped with a shock absorber, such as Figure 5 and Figure 6 As shown, the shock absorber 100 includes a piston rod 110 and a sleeve 120, with the piston rod 110 and the sleeve 120 sealed by an oil seal 130. It is understood that since the specific structure and operating principle of the shock absorber 100 are prior art, they will not be described in detail in this embodiment. Based on the above, to eliminate the foaming phenomenon of the oil, the prior art manually fills the sleeve 120 with low-pressure nitrogen. However, manual filling is inefficient, the inflation effect cannot be determined after filling, and it is also prone to damage to the shock absorber 100.

[0042] To resolve the above issues, please refer to Figures 1 to 11, this embodiment provides a shock absorber inflation device, which includes a loading seat 1 and an inflation platform 2, wherein the loading seat 1 is configured to carry the shock absorber 100. It can be understood that the shock absorber 100 placed on the loading seat 1 is fixed to the loading seat 1 by bolts or other fastening methods, and the inflation platform 2 can be sleeved on the outer periphery of the shock absorber 100, and the inflation platform 2 and the shock absorber 100 form an inflation cavity 21. The inflation platform 2 includes a sealing mechanism, a breaking mechanism 23 and an inflation mechanism 24. The sealing mechanism includes a first sealing ring 221 and a second sealing ring 222. The first sealing ring 221 can be sleeved on the outer periphery of the piston rod 110 of the shock absorber 100, and the second sealing ring 222 can be sleeved on the outer periphery of the sleeve 120 of the shock absorber 100. The inflation cavity 21 is formed by the first sealing ring 2 21 and the second sealing ring 222, the breaking mechanism 23 includes a breaking head 231, which is located between the first sealing ring 221 and the second sealing ring 222. After the inflation platform 2 is sleeved on the outer periphery of the shock absorber 100, the breaking head 231 is in the inflation chamber 21, and the breaking head 231 can be inserted between the piston rod 110 and the oil seal 130 of the shock absorber 100, and a gap is formed between the piston rod 110 and the oil seal 130, and the gap is connected to the inflation chamber 21. The inflation mechanism 24 is configured to inflate air into the inflation chamber 21. As the air pressure in the inflation chamber 21 increases, the gap between the piston rod 110 and the oil seal 130 is gradually expanded until a gas channel connecting the inflation chamber 21 and the inside of the sleeve 120 is formed, and the gas filled in the inflation chamber 21 can be filled into the shock absorber 100 through the gas channel.

[0043] Moreover, based on the existing technology, after the sleeve 120 is filled with gas, the piston rod 110 will move outward. Therefore, in order to detect the inflation effect, in this embodiment, in addition to the loading seat 1 and the inflation platform 2, the shock absorber inflation device also includes a pressure detection mechanism 3. The pressure detection mechanism 3 includes a pressure sensor 31. The pressure sensor 31 can be moved to a preset position. When the pressure sensor 31 is at the preset position, the pressure sensor 31 is opposite to the end of the piston rod 110 away from the sleeve 120. After the sleeve 120 is filled with gas, the piston rod 110 can move toward the pressure sensor 31 and press the pressure sensor 31. As the gas filled in the sleeve 120 gradually increases, the pressure value detected by the pressure sensor 31 gradually increases. When the pressure value is equal to the preset value, the inflation is completed.

[0044] As described above, this embodiment forms a sealed inflation chamber 21 on the outer periphery of the shock absorber 100 through the inflation platform 2, and forms a gap for subsequently establishing a gas channel between the oil seal 130 and the piston rod 110 of the shock absorber 100 through the piercing head 231. As the amount of gas filled into the inflation chamber 21 increases, the gap between the oil seal 130 and the piston rod 110 is gradually expanded until a gas channel connecting the inflation chamber 21 and the interior of the sleeve 120 is formed, thereby inflating the sleeve 120. This embodiment can automatically inflate the shock absorber 100 with a high inflation efficiency. Moreover, this embodiment can accurately detect the air pressure inside the sleeve 120 through the pressure sensor 31 to accurately understand the inflation effect, thereby ensuring that a sufficient amount of nitrogen is filled into the shock absorber 100 while avoiding damage to the shock absorber 100 due to excessive filling of gas.

[0045] Furthermore, the shock absorber inflation device also includes a first driving member 41, which is configured to drive the inflation platform 2 to move along the first direction to the outer periphery of the shock absorber 100. When the shock absorber 100 is placed on the loading seat 1, the axial direction of the piston rod 110 is parallel to the first direction. For example, in this embodiment, the shock absorber 100 is placed on the loading seat 1 in a vertical posture, that is, in this embodiment, the first direction is the vertical direction. The first driving member 41 can drive the inflation platform 2 to rise and fall in the vertical direction, so that the inflation platform 2 can descend in the vertical direction to the outer periphery of the shock absorber 100, and cooperate with the shock absorber 100 to form a sealed inflation chamber 21. Moreover, after the inflation is completed, the first driving member 41 can drive the inflation platform 2 to rise in the vertical direction away from the shock absorber 100, so that the shock absorber 100 can be removed from the loading seat 1.

[0046] It is understandable that, in this embodiment, the first driving member 41 may be a linear driving structure such as a cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0047] In addition, the shock absorber inflation device also includes a mounting frame 5, a first driving member 41 is installed on the mounting frame 5, and a slide rail 51 extending along the first direction is also provided on the mounting frame 5. The inflation platform 2 is slidably connected to the slide rail 51, thereby ensuring that the first driving member 41 can drive the inflation platform 2 to move accurately along the first direction, thereby ensuring that the inflation platform 2 can be accurately mounted on the outer periphery of the shock absorber 100, and cooperate with the shock absorber 100 to form a sealed inflation chamber 21.

[0048] As shown above, the inflation mechanism 24 includes an inflation head 241 and an air source (not shown in the figure). The inflation head 241 connects the inflation chamber 21 and the air source. The air source can inflate the inflation chamber 21 through the inflation head 241, thereby expanding the gap between the oil seal 130 and the piston rod 110 to form a gas channel, and can inflate the sleeve 120 through the gas channel.

[0049] It is understandable that since the structure and working principle of the gas source are both existing technologies, they will not be described in detail in this embodiment.

[0050] Based on the content mentioned above, in order to form a gap between the piston rod 110 and the oil seal 130, the air-breaking head 231 includes at least two plugs 2311, and the at least two plugs 2311 are arranged around an axis extending along the first direction. At least two plugs 2311 can be gathered and jointly sleeved on the outer periphery of the piston rod 110. For example, this embodiment is explained by taking the air-breaking head 231 as an example including two plugs 2311. In this embodiment, the two plugs 2311 are relatively arranged along a second direction perpendicular to the first direction. The air-breaking mechanism 23 also includes a driving part 232, and the two plugs 2311 are correspondingly provided with a driving part 232. The driving part 232 is used to drive the plug 2311 to move along the second direction, so that the two plugs 2311 can be gathered and jointly sleeved on the outer periphery of the piston rod 110.

[0051] It is understandable that, in this embodiment, the driving portion 232 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0052] In addition, the shock absorber inflation device also includes a second driving member 42, which is configured to drive the piercing head 231 to move along the first direction and insert the plug 2311 between the oil seal 130 and the piston rod 110, thereby stretching the oil seal 130 to form a gap between the oil seal 130 and the piston rod 110.

[0053] It is worth noting that the two plugs 2311 gathered and jointly sleeved on the outer circumference of the piston rod 110 can provide a guide for the overall movement of the piercing head 231 so that the two plugs 2311 can be accurately inserted between the oil seal 130 and the piston rod 110.

[0054] After the inflation is completed, the two plugs 2311 move away from each other, thereby facilitating the subsequent vertical ascent of the inflation platform 2 to move away from the shock absorber 100 .

[0055] It is understandable that, in this embodiment, the second driving member 42 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0056] Based on the above, specifically, in this embodiment, the shock absorber inflation device also includes a mounting seat 6, the second driving member 42 is fixedly mounted on the mounting seat 6, the mounting seat 6 is slidably connected to the slide rail 51 through the slider 61, and the inflation platform 2 is installed on the movable end of the second driving member 42. The first driving member 41 can drive the mounting seat 6 to move along the first direction, thereby driving the inflation platform 2 to move along the first direction. In addition, the second driving member 42 can drive the inflation platform 2 to move alone along the first direction, so that the breaking head 231 can move along the first direction.

[0057] Based on the above, the piercing head 231 is located between the first sealing ring 221 and the second sealing ring 222. In addition, in this embodiment, the thickness of the plug 2311 gradually decreases from the side away from the second sealing ring 222 to the side close to the second sealing ring 222, that is, the side of the plug 2311 close to the second sealing ring 222 is thinner, thereby facilitating the insertion of the plug 2311 between the piston rod 110 and the oil seal 130.

[0058] Furthermore, a tip 23111 is formed on the side of the plug 2311 close to the second sealing ring 222, that is, for the side of the plug 2311 close to the second sealing ring 222 along the first direction, the circumferential length of the circle extending along the first direction is smaller, thereby making it easier for the plug 2311 to be inserted between the piston rod 110 and the oil seal 130, and at the same time making it easier to stretch the oil seal 130 to form a gap between the oil seal 130 and the piston rod 110.

[0059] In addition, it should be noted that in this embodiment, the pressure sensor 31 is opposite to the end of the piston rod 110 away from the sleeve 120 along the first direction, and the pressure detection mechanism 3 also includes a third driving member 32, which is configured to drive the pressure sensor 31 to move along the first direction, so that the pressure sensor 31 can move to a preset position.

[0060] It is understandable that, in this embodiment, the third driving member 32 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0061] As described above, the pressure detection mechanism 3 also includes a guide module 33, which is configured to guide the pressure sensor 31 to move along the first direction, so that the pressure sensor 31 can accurately move to the preset position, thereby ensuring that the pressure sensor 31 can accurately detect the air pressure inside the sleeve 120.

[0062] In this embodiment, the guide module 33 includes four guide rods 331, and the four guide rods 331 are all installed on the mounting seat 6. The guide rods 331 extend along the first direction. In addition to the four guide rods 331, the guide module 33 also includes a mounting plate 332. The pressure sensor 31 is arranged on the mounting plate 332, and the mounting plate 332 is sleeved on the outer periphery of all guide rods 331. The third driving member 32 is fixedly installed on the mounting seat 6 and can drive the mounting plate 332 to move along the first direction. In this embodiment, the guide rod 331 is used to provide a guiding effect on the movement of the pressure sensor 31, thereby ensuring that the pressure sensor 31 can accurately detect the air pressure inside the sleeve 120.

[0063] It is understandable that in other optional embodiments, the guide module 33 may also include two, three, five or other numbers of guide rods 331, and this embodiment does not impose any specific limitation on this.

[0064] As described above, in this embodiment, when the first driving member 41 drives the mounting seat 6 and drives the inflation platform 2 to move along the first direction, the third driving member 32 and the mounting plate 332 move together with the mounting seat 6. After the inflation platform 2 moves along the first direction to the outer periphery of the shock absorber 100, the third driving member 32 drives the mounting plate 332 to move alone along the first direction, thereby adjusting the pressure sensor 31 to move to a preset position.

[0065] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
