Description

Technical Field

[0001] The present invention belongs to the technical field of shock absorbers, and in particular relates to an electromagnetically reinforced air compression shock absorber, an air conditioner and a control method. Background Art

[0002] With the development of society and the advancement of science and technology, many equipment used in earthquake zones, nuclear islands, ships, mines and other places have put forward relatively high requirements for seismic performance. However, electronic equipment generally has poor seismic performance, especially air-conditioning outdoor units, which often vibrate violently during operation. The current common practice in the industry to address this problem is to add shock absorbers to the equipment.

[0003] However, most shock absorbers cannot adjust their damping performance based on vibration frequency and amplitude. A single shock absorber model can only provide damping for a specific weight range, vibration frequency, and vibration acceleration range. Once the range is exceeded, the damping effect is greatly reduced, and the shock absorber may even be damaged. This makes it impossible to simultaneously meet the damping requirements of different ranges. Currently, to address this issue, a graded damping solution is commonly used. This involves installing shock absorbers that meet different vibration ranges on the base of the same air conditioner outdoor unit to expand the equipment's seismic resistance range. However, this solution has high equipment costs and a high failure rate. It also suffers from unsatisfactory damping performance, increased equipment size, and increased weight. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides an air compression shock absorber, an air conditioner and a control method using electromagnetic reinforcement.

The upper electromagnetic plate is disposed on the upper barrel, and the lower electromagnetic plate is disposed on the lower barrel. The upper and lower electromagnetic plates are located on the same vertical axis and are both connected to the controller. The controller is connected to the vibration meter, which is used to measure vibration data of the unit under test and control the current direction and magnitude of the two electromagnetic plates through the controller. Limit structures are provided on both the upper barrel and the lower barrel to limit the movement range of the upper barrel.

[0007] The vibration meter includes: a displacement sensor and an acceleration sensor. Both the displacement sensor and the acceleration sensor are set on the unit to be tested and connected to the controller. The sensitive axis direction of the two sensors is consistent with the vibration direction of the unit. The displacement sensor adjusts the current direction of the upper and lower electromagnetic plates by detecting the vibration direction of the unit, so that the upper and lower electromagnetic plates produce an attractive or repulsive force, allowing the upper barrel and the lower barrel to move closer or farther away to adjust the shock absorption direction. The acceleration sensor adjusts the current size of the upper and lower electromagnetic plates by detecting the vibration acceleration of the unit, and controls the force size to adjust the shock absorption performance.

[0008] Preferably, the displacement sensor presets a zero point displacement value d0 through the controller when the unit to be tested is static. The controller is connected to the upper electromagnetic plate and the lower electromagnetic plate through H bridge 1 and H bridge 2 respectively. When the displacement sensor outputs a displacement value d t When the displacement value is greater than the zero point d0, the unit is determined to be vibrating upward.

[0015] Preferably, the force F(x) generated by the upper electromagnetic plate and the lower electromagnetic plate through I(t) is:

[0016] F(x)=μ0π[I(t) 2 ]R 2 / [2(R 2 +x 2 ) 3 / 2 ];

[0017] Wherein, μ0 is the vacuum magnetic permeability, R is the radius of the upper and lower electromagnetic plates; x is the vertical axis distance between the upper and lower electromagnetic plates;

[0018] When the upper and lower electromagnetic plates are energized, their magnetic poles become identical, generating a repulsive force F(x). The upper electromagnetic plate is driven by this repulsive force, which drives the upper barrel upward until it stops moving. The repulsive force F(x) is dynamically adjusted by the current I(t).

[0019] When the upper and lower electromagnetic plates are energized, their magnetic poles become opposite, generating an attractive force F(x). The upper electromagnetic plate is affected by the attractive force and drives the upper barrel downward until it stops moving downward. The attractive force F(x) is dynamically adjusted by the current I(t).

The current direction of the upper and lower electromagnetic plates is adjusted based on the vibration direction, causing the plates to generate an attractive or repulsive force, allowing the upper and lower barrels to move closer or further apart to adjust the direction of shock absorption. Simultaneously, the current levels of the upper and lower electromagnetic plates are adjusted based on the vibration acceleration, controlling the force to adjust the shock absorption performance. This allows precise adjustment of both the direction and performance of shock absorption, significantly improving the damping effect, increasing flexibility and intelligence, and meeting the shock absorption requirements of different amplitude ranges.

[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.

[0038] like Figure 1-3 As shown, the present invention discloses an air compression shock absorber using electromagnetic reinforcement, comprising: an upper barrel, a lower barrel, an upper electromagnetic plate 3, a lower electromagnetic plate 4, a controller 7, a vibration meter 9 and a limit structure.

[0039] An upper electromagnetic plate 3 is provided on the upper barrel, and a lower electromagnetic plate 4 is provided on the lower barrel. The upper electromagnetic plate 3 and the lower electromagnetic plate 4 are located on the same vertical axis and are both connected to a controller 7. The controller 7 is connected to a vibration meter 9. The vibration meter 9 is used to measure the vibration data of the unit to be tested and control the current direction and magnitude of the two electromagnetic plates through the controller 7. Limiting structures are provided on both the upper barrel and the lower barrel to limit the movement range of the upper barrel.

[0040] The vibration meter 9 includes: a displacement sensor and an acceleration sensor. Both the displacement sensor and the acceleration sensor are arranged on the unit to be tested and connected to the controller 7. The sensitive axis direction of the two sensors is consistent with the vibration direction of the unit. The displacement sensor adjusts the current direction of the upper and lower electromagnetic plates by detecting the vibration direction of the unit, so that the upper and lower electromagnetic plates generate an attractive or repulsive force, allowing the upper barrel and the lower barrel to move closer or farther away to adjust the shock absorption direction. The acceleration sensor adjusts the current size of the upper and lower electromagnetic plates by detecting the vibration acceleration of the unit, and controls the force size to adjust the shock absorption performance.

[0041] Preferably, the electromagnetically reinforced air compression shock absorber is arranged on the base of the air conditioner outdoor unit to reduce the vibration of the air conditioner outdoor unit during operation. The present invention can also be placed on other equipment that requires shock absorption.

[0042] The displacement sensor is preset with a zero point displacement value d0 by the controller 7 when the unit to be tested is static. The controller 7 is connected to the upper electromagnetic plate 3 and the lower electromagnetic plate 4 respectively through the H bridge 1 and the H bridge 2. When the displacement sensor outputs the displacement value d t When the displacement value is greater than the zero point displacement value d0, the unit is determined to be vibrating upward. When the displacement value is less than the zero point displacement value d0, the unit is determined to be vibrating downward. When the unit vibrates upward, the controller 7 controls the current of the upper and lower electromagnetic plates in the same direction through the H bridge, so that the magnetic poles are in opposite directions to generate attraction, and the upper barrel moves downward to reduce the upward vibration force. When the unit vibrates downward, the controller 7 controls the current of the upper and lower electromagnetic plates in the opposite directions through the H bridge, so that the magnetic poles are in the same direction to generate mutual repulsion, driving the upper barrel to move upward to reduce the downward vibration force.

[0043] The acceleration sensor measures the vibration acceleration of the unit under test at time t as at. The controller 7 analyzes and processes the acceleration data and adjusts the current I(t) in the upper and lower electromagnetic plates. I(t) conforms to the formula:

[0044]

[0045] K p The proportional gain is used to respond to acceleration errors, Ki is the integral gain used to accumulate historical acceleration errors, and Kd is the differential gain used to predict vibration change trends. All three are preset using the Ziegler-Nichols step response method and determined through experimental adjustments.

[0046] When the acceleration a at time t t The bigger the K p a t The larger it is, the controller (7) will increase the current I(t) of the upper and lower electromagnetic plates;

[0047] T s is the sampling period, every interval T s Read the acceleration value a of the acceleration sensor once i , is a from the initial time to time t i When there are other continuous vibration disturbances in the unit, only K p a t Control I(t) will have residual vibration, through Continuously accumulate acceleration to make Drive I(t) to increase until it is sufficient to offset the vibration interference;

[0048] a t-1 is the previous sampling period Ts The acceleration value of the acceleration sensor is read, (a t -a t-1 ) / T s is a sampling period T s The acceleration change rate within the t -a t-1 ) / T s Predict vibration trends and adjust current I(t) in advance.

[0049] The upper electromagnetic plate 3 and the lower electromagnetic plate 4 are circular ring structures and are located on the same vertical axis. The magnetic field B(x) generated by the two electromagnetic plates when the vertical axis spacing is x conforms to the formula:

[0050] B(x)=μ0[I(t)]R 2 / [2(R 2 +x 2 ) 3 / 2 ]

[0051] Where μ0 is the vacuum magnetic permeability, usually 4π×10-7T·m / A; R is the ring radius of the upper and lower electromagnetic plates;

[0052] At the same time, the upper electromagnetic plate 3 and the lower electromagnetic plate 4 form a force through the magnetic field generated by I(t), and the force conforms to the formula:

[0053] F(x)=μ0π[I(t) 2 ]R 2 / [2(R 2 +x 2 ) 3 / 2 ];

[0054] In a specific embodiment, when the unit moves upward, current flows in the same direction through the upper electromagnetic plate 3 and the lower electromagnetic plate 4, generating mutually attracting magnetic fields of opposite polarity. The upper electromagnetic plate 3 is affected by the attractive force F(x), which drives the upper barrel downward. As the upper barrel moves downward, x decreases and F(x) increases. When the upper electromagnetic plate 3 is restricted by the limit structure and stops moving downward, x remains fixed. The attractive force F(x) is dynamically adjusted by adjusting the current I(t).

[0055] When the unit moves downward, currents in opposite directions flow through the upper electromagnetic plate 3 and the lower electromagnetic plate 4, generating magnetic fields of the same polarity that repel each other. The upper electromagnetic plate 3 is affected by the repulsive force F(x), which drives the upper barrel to move upward. As the upper barrel moves upward, x increases and F(x) decreases. When the upper electromagnetic plate 3 is restricted by the limit structure and stops moving upward, x remains fixed. The repulsive force F(x) is dynamically adjusted by adjusting the current I(t).

[0056] The present invention adaptively adjusts the force F(x) according to the vibration acceleration, achieves precise adjustment of the shock absorption performance, improves the flexibility and intelligence of use, and can meet the shock absorption requirements of different amplitude ranges.

[0058] The limiting structure includes: a lower barrel stop sealing structure 5 and an upper barrel stop sealing structure 6. The lower barrel stop sealing structure 5 is set on the inner circumference of the upper end of the lower barrel structure 2, and the upper barrel stop sealing structure 6 is set on the outer circumference of the lower end of the upper barrel structure 2 at a position corresponding to the lower end of the lower barrel stop sealing structure 5. The lower barrel stop sealing structure 5 and the upper barrel stop sealing structure 6 jointly limit the movement range of the upper barrel.

[0059] An air pump 8 is provided on the outer peripheral surface of the bottom of the lower barrel structure 2 corresponding to the upper side of the bottom plate 11. The air pump 8 is circuit-connected to the controller 7. The controller 7 controls the air pump 8 to adjust the operating efficiency according to the vibration acceleration to ensure pressure balance during the shock absorption process and avoid a decrease in shock absorption performance due to a decrease in pressure. At the same time, the pressure is adjusted by air, which saves space, volume and weight.
