DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present invention should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The above-mentioned features or features mentioned in the specific examples mentioned in the present invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] Example

[0030] like Figure 1 As shown, the present invention provides a shock absorber for realizing automatic variable damping based on a temperature sensing adjustment mechanism, comprising a shock absorber 1, a high temperature adjustment mechanism 3, a low temperature adjustment mechanism 4 and a nitrogen cylinder 2. The compression chamber 11 of the shock absorber 1 is connected to the compression channel 21 of the nitrogen cylinder 2 through a compression oil pipe, and the stretching chamber 12 of the shock absorber 1 is connected to the stretching channel 22 of the nitrogen cylinder 2 through a stretching oil pipe. The compression channel 21 is connected to the high temperature adjustment mechanism 3 through a first adjustment hole 33, the high temperature adjustment mechanism 3 is connected to the low temperature adjustment mechanism 4 through an oil hole 34, and the low temperature adjustment mechanism 4 is connected to the stretching channel 22 through a second adjustment hole 41 and a third adjustment hole 42.

[0031] The two sides of the piston rod 13 of the shock absorber 1 are respectively the stretching chamber 12 and the compression chamber 11. The shock absorber 1 is connected with the nitrogen cylinder 2. During the operation of the shock absorber 1, the hydraulic oil flows between the stretching chamber 12, the compression chamber 11 and the nitrogen cylinder 2. According to the temperature change, the first adjustment hole 33, the second adjustment hole 41 and the third adjustment hole 42 are opened or closed independently, and the change of the damping force caused by the different states of the hydraulic oil at different temperatures is compensated or improved.

[0032] Depend on Figure 4 (c) and Figure 4 It can be seen from (d) that when the hydraulic oil temperature is between 50-65°C, the low temperature adjustment mechanism 4 is still in an expansion state to close the second adjustment hole 41, and the third adjustment hole 42 is in an open state. The high temperature adjustment mechanism 3 begins to expand and gradually closes the first adjustment hole 33 and the oil hole 34. This process increases the damping force of the shock absorber 1, compensating for the damping force attenuation caused by the decrease in the viscosity of the hydraulic oil due to the increase in temperature, thereby realizing the automatic adjustment of the damping force in a high temperature environment.

[0033] Depend on Figure 4 As can be seen from (d) in the figure, when the hydraulic oil temperature is greater than 65°C, the low temperature regulating mechanism 4 is still in the expansion state to close the second regulating hole 41, and the third regulating hole 42 is in the open state. After the expansion movement, the high temperature regulating mechanism 3 completely closes the first regulating hole 33 and the oil hole 34. At this time, the stretching channel 22 and the compression channel 21 are not connected, increasing the damping force of the shock absorber 1 at high temperatures.

[0034] Depend on Figure 4 (b) and Figure 4 It can be seen from (c) that when the hydraulic oil temperature is between 15-50°C, the high temperature adjustment mechanism 3 is in an unexpanded state, and the low temperature adjustment mechanism 4 is still in an expanded state to close the second adjustment hole 41, and the first adjustment hole 33 and the third adjustment hole 42 are in an open state, increasing the damping force of the shock absorber 1 when used at room temperature. At this time, the tension channel 22 and the compression channel 21 are connected through the low temperature adjustment oil chamber 47 and the high temperature adjustment oil chamber 31.

[0035] Depend on Figure 4 (a) and Figure 4 It can be seen from (b) that when the hydraulic oil temperature is between 0-15°C, the high temperature adjustment mechanism 3 is in an unexpanded state, and opens the first adjustment hole 33 and the oil hole 34, and the low temperature adjustment mechanism 4 begins to expand and gradually closes the second adjustment hole 41. At this time, the damping force of the shock absorber 1 is reduced, and the increase in damping force caused by the increase in hydraulic oil viscosity is improved, thereby realizing automatic adjustment of the damping force in a low temperature environment.

[0036] Depend on Figure 4 As can be seen from (a) in the figure, when the hydraulic oil temperature is less than or equal to 0°C, the high temperature adjustment mechanism 3 is in an unexpanded state, and the first adjustment hole 33 and the oil hole 34 are opened. The low temperature adjustment mechanism 4 is in an unexpanded state, and the second adjustment hole 41 is fully opened. At this time, the first adjustment hole 33, the second adjustment hole 41 and the third adjustment hole 42 are all in an open state, and the tension channel 22 and the compression channel 21 are fully connected, which improves the situation where the hydraulic oil viscosity increases and the damping force increases at low temperatures.

[0037] like Figure 3 As shown, the high temperature regulating oil passage chamber 31 of the high temperature regulating mechanism 3 is connected with the high temperature regulating chamber 32, and the two sides of the high temperature regulating oil passage chamber 31 are respectively connected with the first regulating hole 33 and the oil passage hole 34. A mounting plate 24 is provided between the high temperature regulating chamber 32 and the oil chamber 23 of the nitrogen cylinder 2, and the mounting plate 24 is connected with the high temperature push rod 351 of the high temperature regulating valve 35. A high temperature regulating housing 354 is provided on the outer sleeve of the high temperature push rod 351, and the end of the high temperature regulating housing 354 away from the high temperature push rod 351 is connected with the high temperature valve core 37, and the end of the high temperature valve core 37 away from the high temperature regulating housing 354 is connected with the high temperature return spring 36.

[0038] When the temperature of the hydraulic oil is within the temperature variation range of the high temperature regulating valve 35, the high temperature regulating mechanism 3 starts to work, and due to the volume expansion of the high temperature phase change wax 352, the high temperature push rod 351 is gradually pushed out of the high temperature regulating housing 354. Since the high temperature push rod 351 is fixedly connected to the mounting plate 24, the high temperature regulating housing 354 drives the high temperature valve core 37 to slide in the high temperature regulating oil chamber 31 in a direction away from the mounting plate 24 during the process of the high temperature push rod 351 moving out of the high temperature regulating housing 354. When the high temperature valve core 37 moves between the first regulating hole 33 and the oil hole 34, the first regulating hole 33 and the oil hole 34 are gradually closed or opened.

[0039] When the temperature range of the hydraulic oil is lower than the temperature range of the high temperature regulating valve 35, the volume of the high temperature phase change wax 352 is reduced, and the high temperature return spring 36 drives the high temperature valve core 37 to move toward the mounting plate 24, and the first regulating hole 33 and the oil hole 34 are opened. At this time, the compression channel 21 and the tension channel 22 are connected through the high temperature regulating oil chamber 31 and the low temperature regulating oil chamber 47.

[0040] The low temperature regulating oil passage chamber 47 of the low temperature regulating mechanism 4 is in communication with the low temperature regulating chamber 46, and the two sides of the low temperature regulating oil passage chamber 47 are respectively in communication with the oil passage hole 34, the second regulating hole 41 and the third regulating hole 42, and the low temperature push rod 432 of the low temperature regulating valve 43 is connected with the mounting plate 24. A low temperature regulating housing 431 is provided on the outer sleeve of the low temperature push rod 432, and the end of the low temperature regulating housing 431 away from the low temperature push rod 432 is connected to the low temperature valve core 45, and the end of the low temperature valve core 45 away from the low temperature regulating housing 431 is connected to the low temperature return spring 44.

[0041] When the temperature of the hydraulic oil is within the temperature variation range of the low-temperature regulating valve 43, the low-temperature regulating mechanism 4 starts to work, the volume of the low-temperature phase-change wax expands, and the low-temperature push rod 432 is gradually pushed out of the low-temperature regulating housing 431. Since the low-temperature push rod 432 is fixedly connected to the mounting plate 24, during the process of the low-temperature push rod 432 moving out of the low-temperature regulating housing 431, the low-temperature regulating housing 431 drives the low-temperature valve core 45 to slide in the low-temperature regulating oil chamber 47 in the direction away from the mounting plate 24. When the low-temperature valve core 45 moves, the second regulating hole 41 is gradually closed, the second regulating hole 41 is away from the third regulating hole 42, and the third regulating hole 42 is not closed. When the temperature of the hydraulic oil is lower than the temperature variation range of the low-temperature regulating valve 43, the volume of the low-temperature phase-change wax shrinks, and the low-temperature return spring 44 drives the low-temperature valve core 45 to move in the direction close to the mounting plate 24, and the second regulating hole 41 is opened.

[0042] The high temperature regulating valve 35 is partially located in the high temperature regulating chamber 32, and the high temperature return spring 36 is located in the high temperature regulating oil chamber 31. The outer wall of the high temperature valve core 37 is slidably connected to the inner wall of the high temperature regulating oil chamber 31, and the high temperature valve core 37 matches the size of the high temperature regulating oil chamber 31.

[0043] The low temperature regulating valve 43 is partially located in the low temperature regulating chamber 46, and the low temperature return spring 44 is located in the low temperature regulating oil chamber 47. The outer wall of the low temperature valve core 45 is slidably connected to the inner wall of the low temperature regulating oil chamber 47, and the low temperature valve core 45 and the low temperature regulating oil chamber 47 match in size.

[0044] like Figure 5 As shown, a first end surface groove 38 is provided between the high temperature valve core 37 and the high temperature regulating valve 35, and the diameter of the high temperature regulating housing 354 is smaller than the diameter of the high temperature regulating oil chamber 31. A second end surface groove 48 is provided between the low temperature valve core 45 and the low temperature regulating valve 43, and the diameter of the low temperature regulating housing 431 is smaller than the diameter of the low temperature regulating oil chamber 47. The first pressure balance hole 371 connects the first end surface groove 38 with the high temperature regulating oil chamber 31, and during the movement of the high temperature valve core 37, the hydraulic oil flows between the high temperature regulating oil chamber 31 and the high temperature regulating chamber 32 accordingly. The second pressure balance hole 451 connects the second end surface groove 48 with the low temperature regulating oil chamber 47, and during the movement of the low temperature valve core 45, the hydraulic oil flows between the low temperature regulating oil chamber 47 and the low temperature regulating chamber 46 accordingly.

[0045] like Figure 2 As shown, a high-temperature phase-change wax 352 and a high-temperature rubber hose 353 are sequentially arranged between the high-temperature regulating shell 354 and the high-temperature push rod 351 of the high-temperature regulating valve 35 from the outside to the inside. The top end of the high-temperature rubber hose 353 is arranged between the high-temperature end cover 355 and the high-temperature phase-change wax 352. The high-temperature push rod 351 is slidably connected to the center of the high-temperature end cover 355. The high-temperature end cover 355 is fixedly connected to the high-temperature regulating shell 354.

[0046] The high temperature phase change wax 352 undergoes a sudden change between 50-65°C, changing from solid to liquid. At this time, the volume of the high temperature phase change wax 352 expands, driving the high temperature rubber hose 353 to push the high temperature push rod 351 to move. The high temperature push rod 351 moves out of the high temperature regulating housing 354 under the action of the high temperature phase change wax 352. Since the high temperature push rod 351 is fixedly connected to the mounting plate 24, the high temperature regulating housing 354 moves relative to the high temperature regulating oil chamber 31. The high temperature rubber hose 353 is provided to prevent the high temperature phase change wax 352 from overflowing from the high temperature regulating valve 35, which affects the subsequent use of the high temperature regulating valve 35.

[0047] A low-temperature phase-change wax and a low-temperature rubber hose are arranged in sequence from the outside to the inside between the low-temperature regulating shell 431 and the low-temperature push rod 432 of the low-temperature regulating valve 43. The top end of the low-temperature rubber hose is arranged between the low-temperature end cover and the low-temperature phase-change wax. The low-temperature push rod 432 is slidably connected to the center of the low-temperature end cover. The low-temperature end cover is fixedly connected to the low-temperature regulating shell 431.

[0048] The low-temperature phase-change wax undergoes a sudden change between 0-15°C, from solid to liquid. At this time, the low-temperature phase-change wax expands in volume, driving the low-temperature rubber hose to push the low-temperature push rod 432 to move. The low-temperature push rod 432 moves out of the low-temperature regulating shell 431 under the action of the low-temperature phase-change wax. Since the low-temperature push rod 432 is fixedly connected to the mounting plate 24, the low-temperature regulating shell 431 moves relative to the low-temperature regulating oil chamber 47. The setting of the low-temperature rubber hose prevents the low-temperature phase-change wax from overflowing from the low-temperature regulating valve 43, which affects the subsequent use of the low-temperature regulating valve 43.

[0049] The diameter of the high temperature regulating oil chamber 31 is smaller than the diameter of the high temperature regulating chamber 32, and the high temperature end cover 355 is located in the annular fixing groove 1 at the top of the high temperature regulating shell 354, and the diameter of the annular fixing groove 1 is larger than the diameter of the high temperature regulating shell 354. The high temperature regulating shell 354 at the first annular fixing groove is located in the high temperature regulating chamber 32, and the lower part of the high temperature regulating shell 354 is located in the high temperature regulating oil chamber 31.

[0050] The diameter of the low temperature regulating oil passage chamber 47 is smaller than the diameter of the low temperature regulating chamber 46, and the low temperature end cover is located in the annular fixing groove 2 at the top of the low temperature regulating shell 431, and the diameter of the annular fixing groove 2 is larger than the diameter of the low temperature regulating shell 431. The low temperature regulating shell 431 at the annular fixing groove 2 is located in the low temperature regulating chamber 46, and the lower part of the low temperature regulating shell 431 is located in the low temperature regulating oil passage chamber 47.

[0051] The length of the high-temperature valve core 37 is greater than that of the low-temperature valve core 45. A first pressure balancing hole 371 is provided in the center of the high-temperature valve core 37. When the high-temperature reset spring 36 drives the high-temperature valve core 37 to move, there is a pressure difference at both ends of the high-temperature valve core 37. The first pressure balancing hole 371 is used to balance the pressure difference at both ends of the high-temperature valve core 37 to avoid a vacuum environment.

[0052] A second pressure balancing hole 451 is provided in the center of the cryogenic valve core 45. When the cryogenic return spring 44 drives the cryogenic valve core 45 to move, there is a pressure difference at both ends of the cryogenic valve core 45. The second pressure balancing hole 451 is used to balance the pressure difference at both ends of the cryogenic valve core 45 to avoid a vacuum environment.

[0053] Therefore, the present invention adopts a shock absorber with the above structure and automatic variable damping based on a temperature sensing adjustment mechanism, which can automatically compensate for attenuation and reduce the damping force under high and low temperature conditions.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
