Description

Technical Field

[0001] The present invention relates to the technical field of inflatable equipment, and in particular to a shock absorber inflatable device. Background Art

[0002] Automobiles are generally equipped with shock-absorbing springs. When passing through uneven roads, shock-absorbing springs can filter the vibration of the road surface, but the spring itself will also have reciprocating motion. In order to suppress the spring jumping, shock absorbers are also provided on the car. Shock absorbers are used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface, thereby accelerating the attenuation of the vibration of the frame and body, and thus improving the driving smoothness of the car. The working principle of the shock absorber is mainly to use the flow of oil between the piston and the cylinder to generate damping, thereby converting the energy of vibration into heat energy, and then playing a role in shock absorption. However, during the working process of the shock absorber, the oil will produce foaming, which will lead to the empty travel and discontinuity of resistance, thereby affecting the shock absorption effect. To solve this problem, the prior art adopts a solution of filling low-pressure nitrogen into the shock absorber to eliminate the foaming phenomenon of the oil, thereby eliminating the empty travel and discontinuity of resistance, and then improving the shock absorption effect.

[0003] However, in the prior art, the shock absorber is generally inflated manually, but the manual inflation efficiency is low, and the inflation effect cannot be known after inflation, and the shock absorber is easily damaged. Summary of the invention

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

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0040] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

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

[0042] To solve the above problems, please refer to Figures 1 to 11 The present 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 load 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 bolt fastening 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, the second sealing ring 222 can be sleeved on the outer periphery of the sleeve 120 of the shock absorber 100, and 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, and the breaking head 231 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 prior art, after the sleeve 120 is filled with gas, the piston rod 110 will move outward. Therefore, in order to detect the inflation effect, in the present 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 located at the preset position, the pressure sensor 31 is directly 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 against the pressure sensor 31. As the gas filled into 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, in this embodiment, a sealed inflation chamber 21 is formed on the outer periphery of the shock absorber 100 through the inflation platform 2, and a gap for establishing a gas channel later is formed 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 inside of the sleeve 120 is formed, thereby inflating the sleeve 120. In this embodiment, the shock absorber 100 can be automatically inflated, and the inflation efficiency is relatively high. Moreover, in this embodiment, the air pressure inside the sleeve 120 can be accurately detected by 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 a 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. By way of 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 a 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 to away from the shock absorber 100, so that the shock absorber 100 can be removed from the loading seat 1.

[0046] It can be understood that, in this embodiment, the first driving member 41 can be selected as 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, this embodiment will not elaborate on them.

[0050] Based on the contents 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, and the at least two plugs 2311 can be gathered and jointly sleeved on the outer periphery of the piston rod 110. By way of example, this embodiment is described by taking the air-breaking head 231 including two plugs 2311 as an example. In this embodiment, the two plugs 2311 are relatively arranged along a second direction perpendicular to the first direction, and the air-breaking mechanism 23 also includes a driving part 232, and the two plugs 2311 are correspondingly provided with a driving part 232, and the driving part 232 is used to drive the plugs 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 can be understood that, in this embodiment, the driving part 232 can be selected as a linear driving structure such as a 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 can be understood that, in this embodiment, the second driving member 42 can be selected as a linear driving structure such as a 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 a 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, thereby enabling the air-breaking head 231 to 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 side of the circle extending along the first direction is smaller, thereby making it easier to insert the plug 2311 between the piston rod 110 and the oil seal 130, and at the same time facilitating the expansion of 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 the present embodiment, the pressure sensor 31 is directly 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 can be understood that, in this embodiment, the third driving member 32 can be selected as a linear driving structure such as a 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 a first direction, so that the pressure sensor 31 can accurately move to a 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 the 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 rods 331 are used to provide guidance for 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 embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
