Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of compressors, and in particular to a safety structure matched with a vibration damping component, a compressor, and a monitoring feedback method for detecting using the safety structure. Background Art
[0002] Currently, most compressors installed on sports equipment in the industry use rubber parts such as vibration dampers for installation. This can effectively reduce the vibration transmitted to the compressor by the sports equipment, thereby more effectively ensuring the normal operation of the compressor. However, using rubber parts for installation instead of the original rigid connection will reduce the security of the connection to a certain extent, because the tensile strength of rubber parts is lower than that of metal parts. See the attached figure of the manual Figure 1-Figure 3 , illustrates the situation in the industry where compressors are installed on moving equipment (represented here by fixed plates). Most of them are installed using vibration dampers (vibration dampers are made of metal and rubber bonded together). This can effectively reduce the vibration transmitted to the compressor by the moving equipment, thereby more effectively ensuring the normal operation of the compressor.
[0003] In addition, taking the vehicle-mounted compressor as an example, the national standard has corresponding vibration resistance tests to simulate the accelerated life test when it is on the vehicle. Considering the bumpy roads and harsh road conditions that the compressor will face during the operation of the vehicle, the simulated extreme conditions will to a certain extent amplify the lack of connection safety.
[0004] Based on the above situation, if inappropriate or unqualified vibration dampers are used, the service life of the vibration dampers will be affected during high-intensity vibration resistance tests and vehicle installation, causing the rubber to break, resulting in the compressor being unable to be fixed and causing violent shaking, abnormal cooling of the air-conditioning system, and even driving safety incidents in severe cases.

[0050] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.
[0051] See also Figures 1-12 The present invention provides a safety structure that cooperates with a vibration damper, including a safety structure 1, wherein the bracket 3 on the device to be supported 2 is supported on a base (the fixed plate 6 in the figure represents the base) through a vibration damper 4, and the device to be supported 2 may be a compressor, and the safety structure 1 is connected to the base and the safety structure 1 is used to limit the range of shaking of the device to be supported 2. In the prior art, for the vibration damper 4 between the compressor and the bracket 3, if an inappropriate or unqualified vibration damper 4 is used, and the working conditions are relatively bad, it is very likely that the rubber part of the vibration damper 4 will break, or the metal and rubber bonding part of the vibration damper 4 will break, thereby causing the compressor to be unable to be fixed, resulting in violent shaking, and causing abnormal cooling of the air-conditioning system. In severe cases, even a driving safety incident may occur (the compressor is a vehicle-mounted compressor); in response to the above safety hazards, the present invention provides a safety structure that cooperates with a vibration damper, see Figure 4-11 The safety structure 1 can limit the range of vibration of the compressor, which is beneficial to improving the safety of the compressor and the vibration damping member 4, thereby avoiding violent vibration of the compressor as much as possible.
[0052] As an optional implementation method of the embodiment of the present invention, the specific structure of the safety structural member 1 can be as follows: Figure 4-Figure 8 The safety structure 1 includes an upper limit portion 111 for limiting the upward movement range of the bracket 3. The upper limit portion 111 is located above the bracket 3 and is spaced apart from the bracket 3. The upper limit portion 111 allows the compressor to reasonably shake upward under the action of the vibration damper 4, and protects the vibration damper 4, preventing the vibration damper 4 from failing due to stretching and from breaking due to excessive stretching. If the vibration damper 4 breaks, the limit portion 11 will restrict the compressor from continuing to move away from the fixed plate 6, thereby limiting the range of the compressor's shaking and preventing the compressor from shaking violently.
[0053] As an optional implementation method of the embodiment of the present invention, taking into account the deformation of the vibration damper caused by the working conditions, the following limitations can be made on the spacing between the upper limit portion 111 and the bracket 3: the spacing between the upper limit portion 111 and the bracket 3 is h1 (h1 is the initial value of the spacing during installation), and the maximum axial elastic stretch of the vibration damper 4 is Y max1 The maximum axial plastic stretch of the vibration damper 4 is Y max2The compression amount of the vibration damper 4 under installation is △h (the compression amount △h is the deformation amount of the vibration damper 4 in the installed state compared with the uninstalled state), where h1-△h≤Y max1 , or, Y max1 max2 , or, h1-△h≥Y max2 ; and when h1-△h≤Y max1 When Y is used, it is to protect the vibration damper in normal use, that is, the upper limit portion 111 limits the movement of the vibration damper 4 to the maximum axial elastic stretch, so as to protect the vibration damper 4; when Y max1 max2 , is to protect the vibration damper when it is damaged but not broken; when h1-△h≥Y max2 When the vibration damper is broken, it is used to protect the vibration damper 4. When the use range of the vibration damper 4 is expanded, the vibration damper 4 is allowed to have a short-term or instantaneous axial extension greater than Y max2 , to protect the vibration damping parts and compressor.
[0054] As an optional implementation of the embodiment of the present invention, the distance between the upper limit portion 111 and the bracket 3 is adjustable. By adjusting the distance between the upper limit portion 111 and the bracket 3, the vibration damping member 4 can be protected in different usage states.
[0055] As an optional implementation method of the embodiment of the present invention, taking into account the deformation of the vibration damper due to the working conditions, the diameter of the section of the safety structure 1 inserted into the mounting hole 31 can be defined as follows: the safety structure 1 is inserted into the mounting hole 31 on the bracket 3, and the diameter of the section of the safety structure 1 inserted into the mounting hole 31 is d1, the diameter of the mounting hole 31 is L1, and the maximum radial elastic deformation of the vibration damper 4 is X max1 The maximum radial plastic deformation of the vibration damper 4 is X max2 , where 0.5*(L1-d1)≤X max1 , or, X max1 <0.5*(L1-d1) <X max2 , or, 0.5*(L1-d1)≥X max2 ; and when 0.5*(L1-d1)≤X max1 When X max1 <0.5*(L1-d1) <X max2 , is to protect the vibration damper when it is damaged but not broken; when 0.5*(L1-d1)≥X max2 It is to protect the vibration damper in the event of a breakage.
[0056] As an optional implementation method of the embodiment of the present invention, see Figures 8-11 The safety structure 1 includes a lower limit portion 112 for limiting the downward movement range of the bracket 3. The lower limit portion 112 is located below the bracket 3 and there is a distance between the lower limit portion 112 and the bracket 3. The lower limit portion 112 allows the compressor to reasonably swing downward under the action of the vibration damper 4, and has a protective effect on the vibration damper 4, trying to avoid the vibration damper 4 from failing due to compression, and trying to avoid the vibration damper 4 from breaking due to excessive compression.
[0057] As an optional implementation method of the embodiment of the present invention, the distance between the lower limit portion 112 and the bracket 3 is h2 (h2 is the initial value of the distance during installation), and the maximum axial elastic compression of the vibration damper 4 is Z max1 The maximum axial plastic compression of the vibration damper 4 is Z max2 The compression amount of the vibration damper 4 under installation is △h (the compression amount △h is the deformation amount of the vibration damper 4 in the installed state compared with the uninstalled state), where h2+△h≤Z max1 , or, Z max1 <h2+△h<Z max2 , or, h2+△h≥Z max2 ; and when h2+△h≤Z max1 When Z is used, it is to protect the vibration damper in normal use, that is, the lower limit portion 112 limits the movement of the vibration damper 4 to the maximum axial elastic compression amount to protect the vibration damper 4; when Z max1 <h2+△h<Z max2 , is to protect the vibration damper when it is damaged but not crushed; when h2+△h≥Z max2 When the vibration damper is crushed, it is used to protect the vibration damper 4 in the state of compression. In order to expand the scope of use of the vibration damper 4, the vibration damper 4 is allowed to produce a short-term or instantaneous axial compression greater than Z max2 .
[0058] As an optional implementation of the embodiment of the present invention, the distance between the lower limit portion 112 and the bracket 3 is adjustable. By adjusting the distance between the lower limit portion 112 and the bracket 3, the vibration damping member 4 can be protected in different usage states.
[0059] As an optional embodiment of the present invention, safety structural member 1 is provided with a sensor 5 for real-time detection of the position of safety structural member 1 and bracket 3. Sensor 5 is connected to a detection and feedback system. The detection and feedback system processes the signal value obtained from sensor 5 and compares the processed signal value with the initial value stored in the system to determine the safety status of vibration damping member 4 and the supported equipment 2. By configuring the sensor and the detection and feedback system, the condition of the compressor and vibration damping member 4 can be monitored, thereby improving safety.
[0060] As an optional implementation method of the embodiment of the present invention, see Figure 4-Figure 7 A sensor 5 is provided on the upper limit portion 111 of the safety structure 1, and the sensor 5 is a first sensor. The first sensor can be a displacement sensor. The first sensor is used to monitor the distance between the upper limit portion 111 and the bracket 3. When the signal value H1 obtained by processing the signal of the first sensor and the initial value h1 of the distance between the upper limit portion 111 and the bracket 3 stored in the system satisfy H1 / h1<θ1, it is judged that it is unsafe and the vibration damping component 4 may be damaged. The judgment result is fed back to the user to remind the user; in addition, θ1 is the reliability percentage value stored in the system, and the value range of θ1 is greater than 0 and less than 100%.
[0061] As an optional implementation method of an embodiment of the present invention, a sensor 5 is provided on the lower limit portion 112 of the safety structure 1, and the sensor 5 is a second sensor. The second sensor can be a displacement sensor. The second sensor is used to monitor the distance between the lower limit portion 112 and the bracket 3. When the signal value H2 obtained by processing the second sensor and the initial value h2 of the distance between the lower limit portion 112 and the bracket 3 stored in the system satisfy H2 / h2<θ2, it is judged that it is unsafe and the shock absorber 4 may be damaged. The judgment result is fed back to the user to remind the user; in addition, θ2 is the reliability percentage value stored in the system, and the value range of θ2 is greater than 0 and less than 100%.
[0062] As an optional implementation of the embodiment of the present invention, the following description is given for the processed signal value H: the system storage value also includes a period T, and the processed signal value H is the average value of the Z signal values detected by the sensor 5 within the period T. The Z signal values are the Z minimum values of all signal values detected by the sensor 5 within the period T. The Z signal values are part of all signal values detected by the sensor 5 within the period T, that is, the average value of all signal values detected by the sensor 5 within the period T is not calculated; or the processed signal value h0 is the minimum value h of the N signal values detected by the sensor 5 within the period T. min , N signal values are all signal values detected by sensor 5 within period T.
[0063] As an optional implementation method of the embodiment of the present invention, see Figure 4-Figure 7The safety structure 1 also includes a socket portion 12, a limiting portion 11 (upper limit portion 111) is provided at one end of the socket portion 12 and the two are connected, the circumferential side surfaces of the limiting portion 11 (upper limit portion 111) and the socket portion 12 are both cylindrical surfaces, the cross-sectional diameter of the socket portion 12 is smaller than the diameter of the mounting hole 31, the cross-sectional diameter of the limiting portion 11 (upper limit portion 111) is larger than the diameter of the mounting hole 31, and the end of the socket portion 12 away from the limiting portion 11 (upper limit portion 111) is fixed to the moving equipment, and the socket portion 12 may be provided with a thread for realizing a threaded connection with the base. First, according to the original installation, the two ends of the vibration damper 4 are connected to install the bracket 3 of the compressor on the fixed plate 6. Among them, the function of the bracket 3 is to be used for the installation and connection of the compressor; the function of the vibration damper 4 is to be insulated, flame retardant, and to effectively reduce the vibration transmitted from the moving equipment to the compressor. Then install the safety structure 1. When installing the safety structure 1, insert the safety structure 1 into the installation hole 31, and then rotate the safety structure 1 to achieve the threaded connection between the safety structure 1 and the base. At the same time, the distance h1 between the limit portion 11 (upper limit portion 111) and the bracket 3 can be limited to h1≤Y max1 , or Y max1 ≤h1 <Y max2 , or, h1 ≥ Y max2 The spacing between the limiter 11 (upper limiter 111) and the bracket 3 is adjustable, i.e., the two can be threadedly connected to adjust the desired spacing value h1. Regarding the relationship between the axial spacing R1 between the safety structure 1 and the vibration damper 4 and the cross-sectional diameter r1 of the vibration damper, R1>r1.
[0064] As an optional implementation method of the embodiment of the present invention, see Figures 8-11 The safety structure 1 includes a socket portion 12 and a limiting portion 11 connected to the socket portion 12. The socket portion 12 passes through the bracket 3 and is connected to the base. Preferably, the limiting portion 11 is provided above and below the bracket 3 (the limiting portion can also be provided only below the bracket 3). The cross-sectional diameter of the socket portion 12 is smaller than the diameter of the mounting hole 31, and the cross-sectional diameter of the limiting portion 11 is larger than the diameter of the mounting hole 31. The limiting portion 11 and the socket portion 12 are detachably connected, and the limiting portion 11 and the socket portion 12 can be threaded. The limiting portion 11 provided above the bracket 3 is the upper limit portion 111, and the limiting portion 11 provided below the bracket 3 is the lower limit portion 112. The spacing value h1 between the upper limit portion 111 and the bracket 3 can be limited to h1≤Y max1 , or Y max1 ≤h1 <Y max2 , or, h1 ≥ Y max2 corresponding to the spacing value h2 between the lower limit portion 112 and the bracket 3, can be limited to h2≤Z max1 , or, Z max1 <h2<Z max2, or, h2 ≥ Z max2 .
[0065] As an optional implementation method of the embodiment of the present invention, brackets 3 are provided on both sides of the bottom of the device to be supported 2, and each bracket 3 is provided with at least one safety structure 1. Figure 4-11 , schematically showing that two safety structural members 1 are provided on each bracket 3 , and the two safety structural members 1 are located between the corresponding two vibration damping members 4 .

Figure 7 , schematically shows a safety structure 1 including an upper limit portion 111 installed between the bracket 3 and the base of the compressor. By setting different limits on the distance between the upper limit portion 111 and the bracket 3, the vibration damper 4 can be effectively prevented from failing due to stretching, preventing the vibration damper 4 from breaking due to excessive stretching, limiting the range of upward shaking of the compressor, and at the same time, the safety structure 1 can also limit the radial deformation of the vibration damper 4; see Figures 8-11 , illustrating that a safety structure 1 including an upper limit portion 111 and a lower limit portion 112 is installed between the bracket 3 and the base of the compressor, which not only protects the vibration damper 4 from stretching, but also protects the vibration damper 4 from compression, thereby limiting the range of vibration of the compressor.
[0067] A monitoring and feedback method utilizing a safety structure for detection includes the following steps: monitoring the positional relationship between a safety structure 1 and a bracket 3 to determine the safety status of a vibration damper 4 and a supported device 2, which may be a compressor. Specifically, the spacing between the position limiter 11 of the safety structure 1 and the bracket 3 is monitored in real time. This spacing is then processed and compared with a system-stored initial spacing value between the position limiter 11 and the bracket 3 to determine the safety status of the compressor.
[0068] See also Figure 12 , monitoring and feedback methods can specifically include the following:
[0069] Start the detection system and input the parameter value period T and reliability percentage θ;
[0070] The sensor 5 of the safety structure 1 detects the distance value hi between the limit portion 11 and the bracket 3 in real time;
[0071] Process the spacing value hi within the period T to obtain a processed signal value H, and determine the relationship between H and the initial spacing value h between the limiting portion 11 and the bracket 3;
[0072] If H / h < θ, it is judged to be unsafe, that is, the compressor vibration damping parts may be damaged within the cycle T. The information is fed back to the front-end operation interface, and the user chooses whether to continue monitoring. The system defaults to continue monitoring. If the user does not monitor, the detection system is shut down.
