[0033] In this application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c alone can represent: a, b, c, a and b, a and c, or a, b, and c, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0035] The terms "connected" and "connected" should be understood in a broad sense. For example, the "connected" or "connected" of a circuit structure can refer to not only physical connection, but also electrical connection or signal connection. For example, it can be directly connected, that is, physically connected, or indirectly connected through at least one intermediate element, as long as the circuit is connected, or it can be the internal connection of two elements; signal connection can refer to signal connection through a circuit or through a media medium, such as radio waves. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] The relay connects its internal conductive circuit by making the moving contact and the stationary contact contact. In order to ensure the reliable connection of the internal conductive circuit, the contact pressure of the moving contact and the stationary contact needs to meet certain requirements; therefore, during the production process of the relay, the contact pressure of the relay needs to be debugged so that the contact pressure when the moving contact and the stationary contact are in contact meets the requirements.

[0037] When debugging the contact pressure of the relay, the moving contact support on which the moving contact is located can be debugged so that the moving contact moves in a direction close to the static contact and applies pressure to the static contact; in the process of applying pressure, the debugging is interrupted multiple times and the contact pressure between the moving contact and the static contact is measured until the contact pressure meets the conditions; in the prior art, the size of the pressure applied each time is uncontrollable, and it often takes multiple trials and errors to successfully debug, resulting in low production efficiency.

[0038] The present application provides a contact pressure debugging method for a relay, which is applied to a relay. The contact pressure debugging method of the present application realizes the moving contact and the static contact to move away from or close to each other by rotating the first part. After the first angle is calculated in advance, it is only necessary to control the first part to rotate the first angle in a specific direction to make the moving contact close to the static contact and make the pressure applied by the moving contact to the static contact the target debugging pressure. In this way, the debugging process is saved and the production efficiency is improved.

[0039] Next, through Figure 1 The structure of a relay is exemplified.

[0040] Figure 1 The structural diagram of the relay provided for this application is as follows: Figure 1 As shown, the relay includes a stationary contact 11, a stationary contact support 12, a moving contact 13, a moving contact support 14 and a leaf spring 15. The stationary contact 11 is arranged on the stationary contact support 12, the moving contact 13 is arranged on the leaf spring 15, and one end of the leaf spring 15 is connected to the moving contact support 14.

[0041] Figure 2 A schematic diagram of a stationary contact support 12 and a stationary contact 11 is shown; Figure 3A schematic diagram of a moving contact support 14 and a moving contact 13 is shown.

[0042] according to Figure 2 As shown, the stationary contact 11 and the stationary contact support 12 can be connected in a fixed manner, for example, the stationary contact 11 is welded to the stationary contact support 12, etc.

[0043] like Figure 3 As shown, the moving contact 13 and the leaf spring 15 may also be connected in a fixed connection manner; for example, the moving contact 13 is welded to the leaf spring 15 .

[0044] The moving contact support 14 may specifically include a moving contact support body 141 and a first protrusion, and the moving contact support body 141 and the first protrusion are fixedly connected.

[0045] The first protrusion is composed of a first part 22 and a second part 21; the moving contact support body 141 is connected to the second part 21 of the first protrusion; the second part 21 supports plastic deformation. The first part 22 specifically includes a first part body 221 and a second protrusion 222; one end of the leaf spring 15 is provided with a mounting hole for mounting the second protrusion 222; after the second protrusion 222 is riveted and assembled with the mounting hole of the leaf spring 15, one side of the leaf spring 15 contacts the first part body 221.

[0046] The present application can twist or rotate the first part to cause the second part to undergo plastic deformation, thereby enabling the moving contact to move toward or away from the stationary contact.

[0047] Figure 4 The implementation flow chart of the relay contact pressure debugging method provided in this application; Figure 4 As shown, the debugging method provided by this application includes the following steps:

[0048] S401. Determine a first distance based on a target debugging pressure, wherein the first distance is used to indicate the distance between the moving contact and the stationary contact when a target debugging pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact to elastically deform the leaf spring.

[0049] Exemplarily, the target debugging pressure is a Newton, and the first distance is used to indicate the distance between the moving contact and the static contact after a Newton of force is applied to the moving contact on the leaf spring in a direction away from the static contact.

[0050] The present application does not limit the shapes of the moving contact, the stationary contact, the leaf spring and the first part of the body. The moving contact and the stationary contact may be in the shape of a rectangular parallelepiped, a hemispherical shape or a Figure 2 and Figure 3 The semi-cylindrical type shown, etc.

[0051] The leaf spring can be a cuboid with a very small thickness; the shape of the first part body can also be a cuboid.

[0052] This application uses the static contact as a rectangular parallelepiped, the moving contact as a hemispherical shape, the leaf spring as a rectangular parallelepiped with a very small thickness, and the first part as a rectangular parallelepiped as an example to illustrate how to debug the relay contact pressure. Figure 5 and Figure 6 A schematic diagram showing the positional relationship between the moving contact and the stationary contact before and after a target debugging pressure is applied to the moving contact on the leaf spring in a direction away from the stationary contact.

[0053] Figure 5 This is a schematic diagram of the positional relationship between the moving contact and the stationary contact before the target debugging pressure is applied to the moving contact on the leaf spring, that is, when the leaf spring is in an unstressed state.

[0054] like Figure 5 As shown, the inner side of the stationary contact is fixedly connected to the stationary contact support, and the bottom surface of the moving contact is fixedly connected to the leaf spring. When the leaf spring is in an unstressed state, the inner side of the stationary contact is parallel to the bottom surface of the moving contact.

[0055] exist Figure 5 In the figure, the radius of the moving contact is R, the distance between the plane where the upper surface of the first part is located and the center of the moving contact is L0, the theoretical design distance between the moving contact and the static contact is called the first theoretical design distance, and the first theoretical design distance is S; the distance between the upper surface of the first part and the center of the first part is e, the thickness of the leaf spring is h, the distance between the inner side surface of the first part in contact with the leaf spring and the center of the first part is a; the distance between the center of the first part and the plane where the outer side surface of the static contact is located is d. The center of the first part is recorded as O.

[0056] Before producing relays, the distance between the moving contact and the static contact is designed as a first theoretical design distance S. The manufacturer produces and manufactures relays based on the first theoretical design distance S. The actual distance between the moving contact and the static contact of the manufactured relay to be debugged is recorded as S0.

[0057] When there is no manufacturing error, S0 is the same as S; when there is a manufacturing error, S0 may deviate slightly from S.

[0058] The distance between the upper surface of the first part and the center of the first part, the thickness of the leaf spring, the distance between the inner side surface in contact with the leaf spring in the first part and the center of the first part, and the distance between the center of the first part and the plane where the outer side surface of the static contact is located can use the corresponding theoretical design distances, or can be obtained through actual measurement.

[0059] In some embodiments, the center of the first part is the center of the first part body. The upper surface of the first part is the upper surface of the first part body. The center of the moving contact is the center of the bottom surface of the moving contact.

[0060] The upper surface of the first part is the upper surface of the first part body. The actual distance between the moving contact and the static contact is the actual shortest distance between the outer side of the moving contact and the outer side of the static contact. The distance between the upper surface of the first part and the center of the first part is half the height of the first part; the distance between the inner side of the first part that contacts the leaf spring and the center of the first part is half the width of the first part. The outer side of the moving contact is a hemispherical spherical surface.

[0061] Figure 6 The figure shows the positional relationship between the stationary contact and the moving contact after the target debugging pressure is applied to the moving contact in the direction away from the stationary contact.

[0062] from Figure 6 It can be seen that after the target debugging pressure is applied to the moving contact in a direction away from the static contact, the moving contact moves in a direction away from the static contact, and the leaf spring undergoes elastic deformation.

[0063] Wherein, after the target debugging pressure is applied to the moving contact in the direction away from the static contact, the position of the moving contact is the first position, and the distance between the first position and the first plane (recorded as the second distance) is L; in some embodiments, the first position indicates the center position of the moving contact. Wherein, the first plane is the plane where the upper surface of the first part is located.

[0064] In the present application, the first distance specifically indicates the actual distance S0 between the moving contact and the stationary contact when the leaf spring is in an unstressed state (i.e., the actual distance S0 between the outer side surface of the moving contact and the outer side surface of the stationary contact) + the sum of the horizontal elastic deformation F0 actually occurring at a point on the leaf spring connected to the center of the moving contact when the target debugging pressure is applied to the moving contact on the leaf spring at a position away from the stationary contact. In other words, the first distance is S0+F0.

[0065] In the direction away from the static contact, after the target debugging pressure is applied to the moving contact on the leaf spring to cause the leaf spring to deform elastically, the position of the center of the moving contact is the first position. When no pressure is applied to the moving contact (the leaf spring is not deformed), the position of the center of the moving contact is the second position. When the first part is controlled to rotate in the first direction until the moving contact contacts the static contact (the first part is controlled to rotate in the first direction until the leaf spring is not deformed during the process of the moving contact contacting the static contact), the center position of the moving contact is the third position.

[0066] So, if Figure 6 As shown, the distance between the first position and the second position is equal to F, and the distance between the second position and the third position is equal to S.

[0067] S402: Determine a first angle based on the first distance, the second distance from the first position to the first plane, and the third distance.

[0068] As described above, the first position is the position of the moving contact after the target debugging pressure is applied to the moving contact in the direction away from the static contact; the first plane is the plane where the upper surface of the first part is located; the second distance is Figure 6 The third distance is the distance between the upper surface of the first part and the center of the first part.

[0069] It is understandable that if the first part rotates in the first direction, the moving contact may contact the stationary contact, thereby applying pressure to the stationary contact to deform the leaf spring. When calculating the first angle, this deformation amount also needs to be converted into an angle.

[0070] Therefore, the first angle is the angle that the first part needs to rotate when the first part is controlled to rotate in the first direction to drive the leaf spring to rotate and the moving contact on the leaf spring moves a first distance in the absence of a static contact and a static contact support. When the first part rotates in the first direction, the moving contact moves in a direction close to the static contact.

[0071] In the absence of a stationary contact and a stationary contact support, the leaf spring will not contact any object during rotation, and the leaf spring will not be deformed.

[0072] The first angle is also equal to: the sum of the angle that the first part needs to rotate when the moving contact moves from the second position to the first position and the angle that the first part needs to rotate when the moving contact moves from the second position to the third position.

[0073] The calculation formula of the first angle is shown in Formula 1:

[0074]

[0075] Wherein, θ is the first angle; the first distance is S0+F0, L is the distance between the first position and the upper surface of the first part, which can be calculated by the following embodiment; and e is the third distance.

[0076] Wherein, the third distance is the same as the length of the surface in contact with the leaf spring in the first part; Figure 3 As shown, the shape of the surface of the first portion contacting the leaf spring is a rectangle, and the third distance e is the same as half of the length of the rectangle.

[0077] S403, controlling the first part to rotate in a first direction by a first angle, so that the pressure applied by the moving contact to the static contact is the target debugging pressure.

[0078] Before executing S403 , the leaf spring is in a state without stress, that is, no pressure is applied to the leaf spring, and in this state, the leaf spring does not undergo elastic deformation.

[0079] Figure 6 Shows the stationary contact, moving contact, leaf spring and first partial side view of the relay.

[0080] In the present application, the first part can be controlled to rotate clockwise or counterclockwise, thereby driving the leaf spring to rotate clockwise or counterclockwise, so that the moving contact on the leaf spring moves in a direction away from the static contact or close to the static contact.

[0081] In the present application, the first direction may be the rotation direction of the first part when the moving contact on the leaf spring is close to the stationary contact; for example, Figure 4 As shown in FIG. 1 , when the first part rotates counterclockwise, the moving contact on the leaf spring approaches the stationary contact. When the first part rotates clockwise, the moving contact on the leaf spring moves away from the stationary contact. Figure 4 In the scenario shown, the first direction may be counterclockwise.

[0082] In some embodiments, the executor of the relay contact pressure debugging method of the present application may be an electronic device with control capability, which is connected to the first part. After calculating the first angle, the electronic device controls the first part to rotate along the first direction by a first angle with the center of the first part as the rotation center.

[0083] Next, the process of rotating the first part by the first angle in S403 is described.

[0084] When the first part starts to rotate in the first direction, it drives the leaf spring to rotate in the first direction, so that the moving contact moves in the direction close to the static contact. When the moving contact does not contact the static contact, the leaf spring does not deform. When the first part rotates until the moving contact contacts the static contact, the rotation angle has not reached the first angle. Therefore, the first part continues to rotate. At this time, the moving contact begins to apply pressure to the static contact, and the leaf spring deforms. When the first part rotates to the first angle, the first part stops rotating, and the pressure applied by the moving contact to the static contact is the target debugging pressure.

[0085] The following specifically explains why rotating the center of the first part along the first direction by θ can make the contact pressure of the moving contact and the stationary contact the same as the target debugging pressure. The contact pressure of the moving contact and the stationary contact can also be described as the pressure applied by the moving contact to the stationary contact, or the pressure of the stationary contact on the moving contact.

[0086] It can be understood that the deformation amount of the leaf spring is basically the same when the target adjustment pressure is applied to the moving contact in the direction away from the static contact and when the target adjustment pressure is applied to the position of the center point of the moving contact on the leaf spring in the direction close to the static contact.

[0087] Therefore, if the leaf spring is in an unstressed state and the first part is controlled to rotate along the first direction, when the moving contact just contacts the static contact, the moving contact has not yet applied pressure to the static contact, and the moving contact has not received the reaction force of the static contact. At this time, the distance moved by the moving contact is the same as S0; if the first part is controlled to continue to rotate along the first direction, the moving contact applies pressure to the static contact, and the moving contact receives the reaction force of the static contact, causing the leaf spring to deform; when the angle of rotation of the first part along the first direction reaches θ, the deformation of the leaf spring reaches F0.

[0088] Since the deformation of the leaf spring is F0 when the target debugging pressure is applied to the moving contact in the direction away from the static contact, when the moving contact applies pressure to the static contact, if the deformation of the leaf spring is F0, the pressure applied by the moving contact to the static contact is the target debugging pressure. In this way, the debugging of the relay contact pressure is realized.

[0089] Next, we will explain how Formula 1 is obtained.

[0090] As described above, the first angle is also equal to: the sum of the angle that the first part needs to rotate when the moving contact moves from the second position to the first position and the angle that the first part needs to rotate when the moving contact moves from the second position to the third position.

[0091] Figure 7 A schematic diagram of the positional relationship between the moving contact and the stationary contact after the target debugging pressure is applied in the direction away from the stationary contact provided in an embodiment of the present application.

[0092] like Figure 7 As shown, the third position is connected to the center of the first part, and the first position is connected to the center of the first part, so that the first position, the third position, and the center of the first part form a sector. The distance between the first position and the center of the first part is Ra, the moving contact is hemispherical, and the radius of the moving contact is R.

[0093] Ideally, the leaf spring is controlled to produce a lateral elastic deformation of F. When the leaf spring is in an unstressed state, the angle that the center of the first part needs to twist is the same as the first angle θ, as shown in Formula 2:

[0094]

[0095] Among them, La is the arc length corresponding to θ. Figure 7As shown, L is the distance between the first position and the upper surface of the first part; e is the third distance; S0+F0 is the first distance; R is the radius of the moving contact; d is the distance between the center of the first part and the plane where the outer side surface of the static contact is located.

[0096] In the embodiment of the present application, the first angle is less than 14°. In this case, La=Ra*θ≈S+F.

[0097] The relay designed in the embodiment of the present application ensures that L+e>>S+F+Rd. On this basis, Formula 2 can be transformed into Formula 1.

[0098] Figure 8 The diagram is a position relationship diagram of the stationary contact and the moving contact after the leaf spring is rotated by a first angle along a first direction with the center of the first part as the rotation center and the leaf spring is in an unstressed state.

[0099] After the moving contact applies the target adjustment pressure to the static contact, there is a certain deviation between the direction of the target adjustment pressure P applied by the moving contact to the static contact in an ideal situation and the direction of the target adjustment pressure T applied by the moving contact and the static contact in a real situation, wherein both satisfy Formula 3:

[0100]

[0101] Wherein, Ls is: the vertical distance between the lowest point of the upper surface of the first part after rotation and the third position.

[0102] In the present application, suitable F and L can be selected so that Ls is approximately equal to L, and therefore, T and P are approximately equal.

[0103] In summary, as long as the first part is twisted along the first direction by the first angle, the pressure applied by the moving contact to the static contact is the target debugging pressure.

[0104] The present application provides a method for debugging the contact pressure of a relay, wherein the moving contact of the relay is arranged on a leaf spring, one end of the leaf spring is connected to the first part supported by the moving contact, and the moving contact and the static contact are moved away from or close to each other by rotating the first part. Before debugging the contact pressure, based on the target debugging pressure, the first distance between the moving contact and the static contact is determined when the target debugging pressure is applied to the moving contact on the leaf spring in a direction away from the static contact to deform the leaf spring, and the first angle is determined based on the first distance. The first angle indicates the first angle that the first part needs to rotate when the leaf spring does not undergo elastic deformation and the moving contact of the leaf spring moves horizontally by a first distance. In this way, after the first angle is calculated in advance, it is only necessary to control the first part to rotate the first angle in a specific direction to make the moving contact close to the static contact and make the pressure applied by the moving contact to the static contact the target debugging pressure. In the prior art, when debugging the contact pressure of the relay, the debugging is interrupted several times during the process of applying pressure and the contact pressure between the moving contact and the static contact is measured until the contact pressure meets the conditions; in the prior art, the size of the pressure applied each time is uncontrollable, and it often takes multiple trials and errors to successfully debug, resulting in low production efficiency. It can be seen that compared with the prior art, the present application saves the debugging process and improves production efficiency.

[0105] Next, through Fig. 9 The embodiment specifically describes the process of determining the first distance.

[0106] The present application provides a contact pressure debugging method, in which the first distance can be determined by calculating the deformation amount of the leaf spring. Fig. 9 The implementation flow chart of the method for debugging the relay contact pressure provided in the embodiment of the present application is as follows: Fig. 9 As shown, S401 can be implemented by the following steps:

[0107] S4011. Based on the target debugging pressure, the second distance, the elastic modulus of the leaf spring, the thickness of the leaf spring and the width of the leaf spring, determine the first horizontal elastic deformation of the leaf spring when the target debugging pressure is applied to the moving contact in a direction away from the static contact.

[0108] The second distance is the shortest distance between the first position and the plane where the upper surface of the first part is located.

[0109] The calculation formula for the first horizontal elastic deformation of the leaf spring in S4011 is shown in Formula 4:

[0110]

[0111] Among them, F is the first horizontal elastic deformation, specifically the first horizontal elastic deformation at the center of the moving contact on the leaf spring, which is calculated according to formula 4. Under ideal conditions, the first elastic deformation F is the same as the actual elastic deformation F0 of the leaf spring.

[0112] P is the target debugging pressure; L is the distance between the first position and the upper surface of the first part; b is the width of the leaf spring; E is the elastic modulus of the leaf spring; h is the thickness of the leaf spring. P is preset according to actual needs, E can be determined according to the material of the leaf spring, b and h can be the corresponding theoretical design distances, or can be obtained by measurement; L can be calculated by the following embodiment, which will not be described here.

[0113] Specifically, the first horizontal elastic deformation amount of the leaf spring is the first horizontal elastic deformation amount of the position where the center of the moving contact is located on the leaf spring.

[0114] S4012. Determine the first distance based on the first horizontal elastic deformation of the leaf spring.

[0115] As described above, the first distance is the sum S0+F0 of the actual distance S0 between the static contact and the moving contact and the actual horizontal elastic deformation F0 when the leaf spring is in an unstressed state. In the present application, S0+F0 can be obtained by separately determining S0 and separately determining F0, and then adding the two together; or, S0+F0 can be directly solved according to the corresponding formula. Both methods require first calculating the first horizontal elastic deformation of the leaf spring.

[0116] Next, through Fig.10 The embodiment explains how to calculate the first horizontal elastic deformation amount of the leaf spring by separately determining S0 and separately determining F0.

[0117] Fig.10 The following is a flow chart of the implementation of the relay contact pressure measurement method provided in the embodiment of the present application. Fig.10 As shown, S4012 can be implemented by the following steps:

[0118] Sa1. Determine a first distance based on a first horizontal elastic deformation of the leaf spring and a first theoretical design distance between the moving contact and the static contact when the leaf spring is in an unstressed state.

[0119] As described above, when there is no manufacturing error or the manufacturing error can be ignored, the distance S0 between the moving contact and the stationary contact actually measured when the leaf spring is in an unstressed state is the same as the theoretical design distance S between the moving contact and the stationary contact when the leaf spring is in an unstressed state; therefore, the theoretical design distance S between the moving contact and the stationary contact can be used as the actual distance S0 between the moving contact and the stationary contact.

[0120] In the present application, when the target debugging pressure is applied to the moving contact, the error between the actual horizontal elastic deformation F0 of the center position of the moving contact on the leaf spring and the calculated first elastic deformation F can be ignored, so the first elastic deformation F can be determined as F0.

[0121] In this case, the sum of the first horizontal elastic deformation and the first theoretical distance can be determined as the first distance. In this way, when the manufacturing error is small, the first angle can be quickly calculated, so that the contact pressure of the relay can be quickly debugged.

[0122] Next, through Fig.11 The embodiment illustrates how to directly calculate S0+F0 through the corresponding formula.

[0123] Fig.11 The following is a flowchart of the implementation of the method for debugging the relay contact pressure provided in the embodiment of the present application. Fig.11 As shown, S4012 can be implemented by the following steps:

[0124] Sa2. Based on the first horizontal elastic deformation, determine at least one distance set, the distance set including a fourth distance and a fifth distance.

[0125] Fig.12 A schematic diagram showing the relationship between the fourth distance, the fifth distance and S+F is shown.

[0126] Among them, S0 is the actual distance between the moving contact and the static contact, F1 is the fourth distance, and F2 is the fifth distance.

[0127] Among them, the fourth distance is less than S+F; the fifth distance is greater than S+F.

[0128] The values ​​of the fourth distance and the fifth distance are close to the first horizontal elastic deformation, and the stiffness of the leaf spring is determined more accurately.

[0129] Sa3. For each distance set, determine the first pressure and the second pressure.

[0130] The first pressure is the pressure that needs to be applied to the moving contact in order to make the moving contact move in a direction away from the static contact until the distance between the moving contact and the static contact reaches a fourth distance.

[0131] The second pressure is the pressure that needs to be applied to the moving contact in order to make the moving contact move in a direction away from the static contact until the distance between the moving contact and the static contact reaches a fifth distance.

[0132] For each distance set, Sa3 to Sa6 need to be performed to obtain the sixth distance corresponding to each distance set.

[0133] The first pressure and the second pressure are both measured.

[0134] In the process of making the moving contact move in the direction away from the stationary contact, it is achieved by applying pressure to the moving contact in the direction away from the stationary contact.

[0135] When there are multiple distance sets, each distance set corresponds to a first pressure and a second pressure.

[0136] Sa4. Determine a first stiffness of the leaf spring based on the first pressure, the second pressure, the fourth distance and the fifth distance.

[0137] Among them, the first stiffness of the leaf spring can be determined by formula five.

[0138]

[0139] Among them, P2 is the second pressure, P1 is the first pressure; F2 is the fifth distance, and F1 is the fourth distance.

[0140] When there are multiple distance sets, a first stiffness may be calculated for each distance set.

[0141] Sa5. Determine a sixth distance corresponding to the distance set based on the first stiffness, the first pressure, the target debugging pressure and the fourth distance of the leaf spring.

[0142]

[0143] Among them, F3 is the sixth distance, P is the target debugging pressure; P1 is the first pressure, K is the first stiffness of the leaf spring; F1 is the fourth distance.

[0144] Sa6. Determine the first distance based on the sixth distance corresponding to the entire distance set.

[0145] When the number of distance sets is one, the sixth distance is equal to the first distance, that is, S0+F0=F3.

[0146] When there are multiple distance sets, the sixth distances corresponding to all the distance sets are selected to obtain at least one sixth distance that meets a preset condition.

[0147] Specifically, the average value of the sixth distances corresponding to all the distances is calculated, and the sixth distances whose difference with the average value is greater than a preset threshold are eliminated from all the sixth distances to obtain the at least one sixth distance, and then the first distance is determined based on the average value of the at least one sixth distance.

[0148] In this embodiment, when there is a manufacturing error or an error in the elastic deformation of the leaf spring, there is a certain error between the first theoretical design distance S and S0, and there is an error between F and F0, and S cannot be determined as S0, and F cannot be determined as F0, so the first distance S0+F0 is determined based on S+F. The stiffness of the leaf spring can be measured first, and a more accurate first distance can be determined based on the stiffness of the leaf spring.

[0149] As described above, the second distance L between the first position and the plane where the first part is located is used when calculating the elastic deformation of the leaf spring; next, by Fig.13 The embodiment exemplarily illustrates the implementation method of determining the second distance L.

[0150] Fig.13 A flowchart for implementing the debugging method of the relay contact pressure provided in the embodiment of the present application; Fig.13 As shown, before S402, the method further includes:

[0151] S402a. Construct a deflection curve equation based on the position information of the leaf spring in an unstressed state, the target debugging pressure, the second distance, the elastic modulus of the leaf spring, the thickness of the leaf spring, the width of the leaf spring, and the second elastic deformation of the leaf spring when the target debugging pressure is applied toward the moving contact in a direction away from the static contact.

[0152] The constructed deflection curve equation is shown in Formula 7:

[0153]

[0154] Wherein, x is the position information of the leaf spring in an unstressed state, and x can be the position information of any point on the leaf spring; the position information is used to indicate the distance between the point and the upper surface of the first part; F(x) is the second elastic deformation of the leaf spring; P is the target debugging pressure; L is the second distance; E is the elastic modulus of the leaf spring; b is the width of the leaf spring; and h is the thickness of the leaf spring.

[0155] S402b. Determine a second distance based on the deflection curve equation and the seventh distance.

[0156] The seventh distance is the distance between the moving contact and the upper surface of the first part when the leaf spring is in an unstressed state, that is, the shortest distance between the second position and the upper surface of the first part.

[0157] In some embodiments, the deflection curve equation is first derived to obtain Formula 8 as follows:

[0158]

[0159] Wherein, G(x) is the derivative of the second elastic deformation of the leaf spring. It satisfies the following formula 9 with the seventh distance and the second distance:

[0160]

[0161] Among them, L0 is the seventh distance, specifically the distance between the center of the moving contact and the surface of the first part when the leaf spring is in an unstressed state. The distance can be a corresponding theoretical design distance or can be obtained through measurement.

[0162] Then, by solving Formula 9, the second distance L can be obtained.

[0163] In the present application, the first pressure and the second pressure can be measured by a force displacement sensor. The force displacement sensor has a test rod, which can push the object to move along the test direction. In the process of pushing the object to move along the test direction, the detection element of the force displacement sensor can measure the reaction force of the object on the test rod.

[0164] Next, through Fig.14 The embodiment describes how to measure the first pressure and the second pressure by using a force displacement sensor.

[0165] The present application provides a method for debugging relay contact pressure. Fig.14 Implementation flow chart of the relay contact pressure debugging method provided in the embodiment of the present application; Fig.14 As shown, Sa3 can be implemented in the following ways:

[0166] Sa31. Send a first instruction to the force displacement sensor, where the first instruction is used to instruct the force displacement sensor to control the test rod to push the moving contact to move in a direction away from the static contact until the distance between the moving contact and the static contact is a fourth distance.

[0167] During the test, the test rod of the force displacement sensor approaches the moving contact in a direction away from the static contact, and when in contact with the moving contact, the moving contact is pushed to move in a direction away from the static contact, and the leaf spring is deformed. When the test rod pushes the moving contact until the distance between the moving contact and the static contact is the fourth distance, the force displacement sensor stops pushing the moving contact. At this time, the force displacement sensor measures the first reaction force of the moving contact acting on the test rod of the force displacement sensor, and the first reaction force is the same as the first pressure.

[0168] Sa32, receiving the first response data sent by the force displacement sensor based on the first instruction.

[0169] The first response data is a first reaction force received by the test rod when the test rod pushes the moving contact to move in a direction away from the static contact until the distance between the moving contact and the static contact is a fourth distance.

[0170] Sa33. Send a second instruction to the force displacement sensor, where the second instruction is used to instruct the force displacement sensor to control the test rod to continue pushing the moving contact to move in a direction away from the static contact until the distance between the moving contact and the static contact is the fifth distance.

[0171] Sa33 continues to push the moving contact based on Sa31. The force displacement sensor controls the test rod to continue pushing the moving contact in the direction away from the static contact until the distance between the moving contact and the static contact is the fifth distance, and the force displacement sensor stops pushing the moving contact. At this time, the force displacement sensor measures the second reaction force of the moving contact on the test rod of the force displacement sensor, and the second reaction force is the same as the second pressure.

[0172] Sa34, receiving the second response data sent by the force displacement sensor based on the second instruction.

[0173] The second response data is the second reaction force received by the test rod when the test rod continues to push the moving contact to move in a direction away from the static contact until the distance between the moving contact and the static contact is the fifth distance.

[0174] The second reaction force is the same as the second pressure.

[0175] In this embodiment, during the process of debugging the relay contact pressure, it is only necessary to control the force displacement sensor to push the moving contact to move once in the direction away from the static contact to obtain the first pressure and the second pressure, thereby determining the first stiffness based on the first pressure and the second pressure, determining the first distance based on the first stiffness, and determining the first angle based on the first distance, so as to adjust the contact pressure of the relay according to the first angle. In this way, the efficiency of relay production is saved.

[0176] It should be noted that although the steps of the method in the present application are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.; or, steps in different embodiments may be combined into a new technical solution.
