Description

Technical Field

[0001] This application belongs to the technical field of vibration testing. More specifically, it relates to a vibration testing jig and a vibration testing device. Background Art

[0002] Vibration testing is to simulate the vibration conditions that a product or device may encounter in the actual use environment to evaluate its vibration response and performance. Its main purpose is to ensure that the product or device can work normally in a vibration environment and predict its long-term performance and reliability.

[0003] Taking the vibration testing of a rearview mirror as an example, the tooling for fixing the rearview mirror uses a hinge to fix the rearview mirror. When placed on a vibration table for vibration, the hinge between the tooling and the rearview mirror will bring certain resonance to the product, resulting in the failure of the vibration test and inaccurate test results. Summary of the Utility Model

[0004] The purpose of this application is to provide a vibration testing jig and a vibration testing device to solve the technical problem of resonance occurring between the vibration tooling and the sample to be tested.

[0005] To achieve the above purpose, the first aspect of this application provides a vibration testing jig, including:

[0006] A support member;

[0007] A fixing member for fixedly connecting the product to be tested, and the fixing member is detachably connected to the support member; and

[0008] A connection structure, which includes a protrusion provided on the support member and a groove provided on the fixing member, or includes a groove provided on the support member and a protrusion provided on the fixing member, and the protrusion is snap-fitted with the groove.

[0009] Taking the rearview mirror as the product to be tested as an example, in the prior art, a hinge structure is used to fix the rearview mirror and the bracket, resulting in a large amplitude of the bracket during the vibration test, thus causing resonance with the rearview mirror, and even possibly damaging the rearview mirror, making it impossible to know whether it is a product quality problem of the rearview mirror itself or resonance when analyzing the cause finally.

[0010] The vibration test fixture provided in the embodiment of the present application, by setting a groove on the fixing part and a protrusion on the supporting part (or setting a protrusion on the fixing part and a groove on the supporting part), and by the snap-fitting of the groove and the protrusion, the connection strength between the supporting part and the fixing part (i.e., the product to be tested) is strengthened. Since the protrusion is inserted into the groove, the limiting fit of the two is relatively tight. Compared with the hinge structure fixation in the prior art, the resonance between the supporting part and the fixing part (the product to be tested) can be effectively avoided, thereby ensuring the smooth progress of the vibration test experiment and improving the accuracy of the vibration test.

[0011] Preferably, the surface of the support member is provided with a first texture, the first texture and the protrusion are located on the same surface of the support member, the surface of the fixing member is provided with a second texture, the second texture and the groove are located on the same surface of the fixing member, and the directions of the first texture and the second texture are arranged crosswise. Optionally, the surface of the support member is provided with a first texture, the first texture and the groove are located on the same surface of the support member, the surface of the fixing member is provided with a second texture, the second texture and the protrusion are located on the same surface of the fixing member, and the directions of the first texture and the second texture are arranged crosswise. Thus, through the cross arrangement of the first texture and the second texture, when the protrusion and the groove are buckled and matched, the first texture and the second texture contact each other, thereby increasing the friction between the two. When performing a vibration test, the friction between the first texture and the second texture effectively prevents the relative movement between the support member and the fixing member, thereby avoiding the occurrence of resonance.

[0012] Preferably, the protrusion and the groove are provided with connecting holes, and the connecting holes are used to set a connecting piece to fix the buckle fit of the protrusion and the groove. Thus, the connection fit between the support and the fixing piece can be further improved, and the setting of the protrusion and the groove basically avoids the vibration of the fixing piece and the support in the width and length directions of the groove. By setting the connecting piece in the connecting hole, the protrusion and the groove are fixed and limited in the depth direction of the groove, so as to avoid movement or vibration in the depth direction of the groove during the vibration test.

[0013] Preferably, the support member includes a first supporting portion and a second supporting portion, the second supporting portion has a first side wall that is inclined, the protrusion is arranged on the first side wall, and a clearance space is formed between the first supporting portion and the second supporting portion, and the clearance space is used to accommodate at least part of the product to be tested to save space occupied by the product to be tested.

[0014] Preferably, the first side wall is obliquely arranged on the first supporting portion, and the inclination angle of the first side wall is 10° to 40°. The second supporting portion also has a second side wall arranged back to back with the first side wall, wherein the inclination angle of the first side wall is the angle between the plane where the first side wall is located and the plane where the second side wall is located. In this way, the shapes of different products to be tested can be adapted, and the inclination angle of the concave-convex step structure can be changed. The inclination angle can be set to 10° to 40°, and can be adjusted according to the specific shape of the product to be tested. When multiple vibration test fixtures need to be placed at the same time, the products to be tested can be placed at an angle. Since the distance between the products to be tested is closer, the space for vibration testing can be saved.

[0015] Optionally, the clearance space is a triangular or trapezoidal column space. Thus, the shape of the clearance space is adapted to the shape of the product to be tested, which can save space to the greatest extent.

[0016] Preferably, when there is one protrusion, the protrusion is in a rectangular, elliptical, triangular or irregular shape, and the number and shape of the grooves are set corresponding to the protrusion; thus, the protrusion of the above shape cannot rotate, so as to avoid resonance between the fixing member and the supporting member;

[0017] When there are two or more protrusions, the shape of the protrusions is one of a rectangle, a circle, an ellipse, a triangle or an irregular shape, and the number and shape of the grooves are set corresponding to the protrusions. Therefore, the two or more protrusions can further enhance the connection strength between the fixing member and the supporting member on the one hand, and on the other hand, there is no special requirement for the shape, which can be a circle. In actual production, the circular protrusion is also easier to process and shape.

[0018] Preferably, the fixing member comprises:

[0019] A first fixing part, used to be connected to the product to be tested;

[0020] A second fixing portion connected to the first fixing portion, the protrusion or the groove being arranged on the second fixing portion;

[0021] Wherein, the protrusion or the groove is provided with a connecting hole, and the connecting hole is used to set a connecting piece to fix the snap-fitting fit between the protrusion and the groove.

[0022] Preferably, at least two groups of connection holes are provided, and the two groups of connection holes are symmetrically arranged in the groove or symmetrically arranged on the protrusion. Thus, the screws on the multiple connection holes can fix the second fixing part and the support member respectively, thereby ensuring that the connection and fixation between the second fixing part and the support member is uniform, thereby strengthening the connection and fixation between the second fixing part and the support member to avoid resonance between the support member and the fixing member.

[0023] Preferably, a protrusion is provided on the edge of the first fixing portion, and the protrusion is used for being snap-connected with the product to be tested.

[0024] Optionally, the fixing member further includes a connecting portion, which is arranged around an edge of the second fixing portion and connected to the first fixing portion, and the connecting portion and the first fixing portion enclose a recess to allow the first fixing portion to be snap-fitted with the product to be tested.

[0025] Preferably, the fixing member is integrally formed, that is, the first fixing portion, the second fixing portion and the connecting portion are integrally formed, thereby effectively improving the overall strength of the fixing member, thereby improving the connection strength between the fixing member and the product to be tested, and thus avoiding industrial vibration between the fixing member and the product to be tested.

[0026] Preferably, the vibration test fixture further comprises a base, a plurality of mounting holes are formed on the base, and the plurality of mounting holes are arranged through the base, and the mounting holes are used to set connecting members to fix the connection between the support member, the base and the test bench.

[0027] Preferably, the mounting hole in the middle of the base is used to set a connector to connect the support, and the mounting holes on both sides of the base are used to set a connector to connect the test bench. In this way, the connection strength among the support, the base and the test bench can be strengthened.

[0028] The second aspect of the embodiment of the present application provides a vibration test device, including a test bench and at least one vibration test fixture as described above, wherein the vibration test fixture is arranged on the test bench. Thus, at least one product to be tested can be subjected to a vibration test as required, and when multiple products need to be tested, the vibration test device provided by the embodiment of the present application can effectively save space.

[0043] In the following description, specific details such as specific system architectures and technologies are presented for purposes of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details.

[0044] It should also be understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0045] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0046] It should be understood that the orientation or positional relationships indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application.

[0047] In addition, in the description of the specification and appended claims of the present application, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

Thus, statements such as "in an embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "comprising", "including", "having", and their variants all mean "including but not limited to", unless otherwise specifically emphasized in another way. "Plurality" means two or more.

[0049] Embodiments of the present application provide a vibration test fixture, as Figure 1 and Figure 2 shown, including a support member 10, a fixing member 20, and a connection structure 30;

[0050] The fixing member 20 is used to fixedly connect the product to be tested, and the fixing member 20 is detachably connected to the support member 10;

[0051] The connecting structure 30 includes a protrusion 31 and a groove 32. The protrusion 31 is disposed on the support member 10, and the groove 32 is disposed on the fixing member 20. The groove 32 is snap-fitted with the protrusion 31. Optionally, the protrusion 31 can also be disposed on the fixing member 20, and then the groove 32 is disposed on the support member 10.

[0052] By providing the groove 32 on the fixing member 20 and the protrusion 31 on the support member 10 (or providing the protrusion 31 on the fixing member 20 and the groove 32 on the support member 10), through the snap-fitting of the groove 32 and the protrusion 31, the connection strength between the support member 10 and the fixing member 20 (i.e., the product to be tested) is enhanced. Since the protrusion 31 is inserted into the groove 32, the limit fit between the two is relatively tight. Compared with the hinge structure fixation in the prior art, resonance between the support member 10 and the fixing member 20 (the product to be tested) can be effectively avoided, thereby ensuring the smooth progress of the vibration test experiment and improving the accuracy of the vibration test.

[0053] In the embodiment of the present application, the product to be tested is taken as a rearview mirror. In other embodiments, the product to be tested can be a product that needs to be subjected to a vibration test, such as other automotive parts, electronic products, etc.

[0054] In the embodiment of the present application, as Figure 3 and Figure 4 shown, a first texture 100 is provided on the surface of the support member 10. The first texture 100 and the protrusion 31 are on the same surface of the support member 10. A second texture 200 is provided on the surface of the fixing member 20. The second texture 200 and the groove 32 are on the same surface of the fixing member 20. The directions of the first texture 100 and the second texture 200 are cross-set. Optionally, a first texture 100 is provided on the surface of the support member 10. The first texture 100 and the groove 32 are on the same surface of the support member 10. A second texture 200 is provided on the surface of the fixing member 20. The second texture 200 and the protrusion 31 are on the same surface of the fixing member 20. The directions of the first texture 100 and the second texture 200 are cross-set. Thus, through the cross-setting of the first texture 100 and the second texture 200, when the protrusion 31 and the groove 32 are snap-fitted, the first texture 100 and the second texture 200 come into contact with each other, thereby increasing the friction between the two. When performing a vibration test, the friction between the first texture 100 and the second texture 200 effectively prevents relative movement between the support member 10 and the fixing member 20, and further avoids the occurrence of resonance.

[0055] It should be noted that the first lines 100 and the second lines 200 are arranged in a cross direction, that is, the first lines 100 and the second lines 200 are not parallel, but at a certain angle, to ensure that friction resistance is generated between the first lines 100 and the second lines 200 to avoid resonance between the support 10 and the fixing part 20. The lines are convex strips arranged on the surface of the support 10 or the fixing part 20. Specifically, the shapes of the first lines 100 and the second lines 200 can be one of the shapes of annular, elliptical, rectangular, circular, straight, wavy, etc., and there is an intersection between the first lines 100 and the second lines 200. In some embodiments, such as Figure 3 and Figure 4 As shown, the first lines 100 on the support member 10 are arranged in an annular shape, and the second lines 200 on the fixing member 20 are arranged in a transverse or longitudinal direction. The arranged lines and the annular lines have different directions, so friction is formed to better avoid shaking and reduce resonance.

[0056] In the embodiments of the present application, Figures 1 to 4 As shown, both the protrusion 31 and the groove 32 are provided with connection holes 300, and the connection holes 300 are used to set a connection piece to fix the buckle fit of the protrusion 31 and the groove 32. In this way, the connection fit between the support member 10 and the fixing member 20 can be further improved. The setting of the protrusion 31 and the groove 32 can effectively prevent the fixing member 20 and the support member 10 from vibrating in the width and length directions of the groove 32. By setting a screw at the connection hole 300, the protrusion 31 and the groove 32 are fixed, and the protrusion 31 is limited in the depth direction of the groove 32 to prevent it from moving or vibrating in the depth direction of the groove 32 during the vibration test. In application, the connection piece can be a screw.

[0057] It should be noted that if Figure 6 As shown, the length direction of the groove 32 is the Z direction in the figure, the width direction of the groove 32 is the Y direction in the figure, and the depth direction of the groove 32 is the X direction in the figure. The above is only for the convenience of explanation and understanding of the technical solution of the present application, and should not be understood as limiting the protection scope of the embodiments of the present application.

[0058] In the embodiments of the present application, Figure 5 As shown, the support member 10 includes a first support portion 11 and a second support portion 12, the second support portion 12 has a first side wall 121 arranged obliquely, the protrusion 31 is arranged on the first side wall 121, and a clearance space 110 is formed between the first support portion 11 and the second support portion 12, and the clearance space 110 is used to accommodate at least part of the product to be tested to save the space occupied by the product to be tested. Optionally, the clearance space 110 is a triangular or trapezoidal column space. Therefore, the shape of the clearance space 110 is adapted to the shape of the product to be tested, which can save space to the greatest extent.

[0059] In the embodiments of the present application, Figure 5 As shown, the first side wall 121 is tilted on the first support portion 11, and the tilt angle of the first side wall 121 is 10° to 40°. The second support portion 12 also has a second side wall 122 that is arranged back to back with the first side wall 121, wherein the tilt angle of the first side wall 121 is the angle between the plane where the first side wall 121 is located and the plane where the second side wall 122 is located. In some embodiments, the tilt angle of the first side wall 121 can be any degree within the range of 10° to 40°, such as 10°, 15°, 20°, 25°, 30°, 35°, etc. Therefore, in order to adapt to the shapes of different products to be tested, the tilt angle of the concave-convex step structure can be changed, and the tilt angle can be set to 10° to 40°. Exemplarily, when multiple vibration test fixtures need to be placed at the same time, the products to be tested can be placed at an angle, and since the distance between the products to be tested is closer, the space for vibration testing can be saved. Traditional fixture arrangements often adopt a parallel or vertical layout, which has obvious deficiencies in space utilization. By setting an inclined first side wall, a space with an inclined angle is provided so that multiple test samples can be staggered. By adjusting the inclination angle and relative position of the first side wall, maximum space utilization is achieved.

[0060] Optionally, the first side wall 121 is vertically arranged on the first support portion 11 and is flush with the first support portion 11. Further, the overall dimensions of the second support portion 12 are 100 mm in length, 70 mm in width, and 180 mm in height. The second support portion 12 and the first support portion 11 are integrally formed, and the material of the second support portion 12 and the first support portion 11 can be any one of stainless steel, titanium alloy, nickel-cobalt alloy, specially treated aluminum alloy, and tungsten steel.

[0061] Optionally, the tensile strength of the second support portion and the first support portion is between 800 MPa and 1100 MPa, for example, can be any one of 800 MPa to 900 MPa, 900 MPa to 1000 MPa, 1000 MPa to 1100 MPa, 1100 MPa to 1200 MPa and 1200 MPa to 1300 MPa.

[0062] Preferably, the second support portion and the first support portion are formed of a whole piece of stainless steel. Since the second support portion and the first support portion are integrally formed, the strength is greatly increased, and resonance can be avoided during vibration testing. In other embodiments, the sizes of the second support portion 12 and the first support portion 11 can also be designed to other sizes to adapt to different products to be tested.

[0063] In an embodiment of the present application, when there is one protrusion 31, the shape of the protrusion 31 is one of a rectangle, an ellipse, a triangle, or an irregular shape, and the number and shape of the grooves 32 are correspondingly set with the protrusion 31. It should be noted that when there is only one protrusion 31, the protrusion 31 cannot be set as a circle, otherwise the limiting function will be lost. The protrusion 31 of the above shape cannot rotate and can play a role in limiting and fixing to avoid resonance between the fixing member 20 and the support member 10.

[0064] In an embodiment of the present application, as Figure 1 , Figure 3 and Figure 5 shown, when there are two or more protrusions 31, the shape of the protrusion 31 is one of a rectangle, a circle, an ellipse, a triangle, or an irregular shape, and the number and shape of the grooves 32 are correspondingly set with the protrusion 31. Thus, two or more protrusions 31 can, on the one hand, further enhance the connection strength between the fixing member 20 and the support member 10. In addition, when setting two or more protrusions 31, there is no special requirement for the specific shape of the protrusion 31, and its shape can be set as a circle. In the actual production process, the protrusion 31 designed as a circle is not only convenient for processing and manufacturing, but also easy to achieve precise forming control. Therefore, the circular protrusion 31 has high feasibility in practical applications.

[0065] In an embodiment of the present application, as Figure 6 and Figure 7 shown, the fixing member 20 includes a first fixing portion 21 and a second fixing portion 22,

[0066] The first fixing portion 21 is used to be connected to the product to be tested;

[0067] The second fixing portion 22 is connected to the first fixing portion 21, and the protrusion 31 or the groove 32 is provided on the second fixing portion 22;

[0068] Among them, the protrusion 31 or the groove 32 is provided with a connection hole 300, and the connection hole 300 is used to set a screw to fix the snap-fit of the protrusion 31 and the groove 32. Thus, the connection between the first fixing portion 21 and the product to be tested can be strengthened, and the connection between the second fixing portion 22 and the support member 10 can be strengthened, so as to reduce the shaking and achieve the purpose of avoiding resonance.

[0069] The snap-fit of the protrusion 31 and the groove 32 enhances the connection strength between the support member 10 and the fixing member 20, and improves the stability of the overall structure. Compared with only setting a connecting member for fastening, the direct contact and embedding of the protrusion 31 and the groove 32 form a firm and reliable snap-fit system.

[0070] Specifically, the protrusion 31 and the groove 32 have a consistent shape to ensure that the protrusion 31 can be accurately embedded in the groove 32 to form a tight snap-fit structure. This snap-fit structure can reduce the number of connecting parts such as screws and also prevent the screws from falling off after loosening. In addition, by setting the protrusion 31 and the groove 32, the contact area between the two is greatly increased, thereby effectively increasing the friction force between them. The enhanced friction force makes the connection more stable and can maintain the integrity and stability of the structure under vibration test conditions. In the embodiments of the present application, as Figure 6 and Figure 7 shown, at least two sets of connection holes 300 are provided, and the two sets of connection holes are symmetrically arranged in the groove or the two sets of connection holes are symmetrically arranged on the protrusion.

[0071] Optionally, two protrusions 31 and two grooves 32 are respectively provided. The two grooves 32 are centrosymmetrically arranged on the second fixing part 22, and a set of connection holes 300 are respectively arranged in the two grooves 32, and each set of connection holes 300 is symmetrically arranged in the groove.

[0072] Optionally, two protrusions 31 and two grooves 32 are respectively provided. The two protrusions 31 are centrosymmetrically arranged on the second fixing part 22, and a set of connection holes 300 are respectively arranged on the two protrusions, and each set of connection holes 300 is symmetrically arranged on the protrusion 31.

[0073] Optionally, three connection holes 300 may be provided (not shown in the figure), and the three connection holes 300 are evenly distributed around the center of the second fixing part 22.

[0074] Thus, the screws on the multiple connection holes 300 can respectively fix the second fixing part 22 and the support member 10, thereby ensuring that the connection and fixation between the second fixing part 22 and the support member 10 are uniform, and further strengthening the connection and fixation between the second fixing part 22 and the support member 10 to avoid resonance between the support member 10 and the fixing member 20.

[0075] In the embodiments of the present application, as Figure 6 and Figure 7 shown, a convex block 210 is provided at the edge of the first fixing part 21, and the convex block 210 is used for snap-connecting with the product to be tested.

[0076] In the embodiments of the present application, as Figure 6 and Figure 7As shown, the fixing member 20 further includes a connecting portion 23. The connecting portion 23 is disposed around the edge of the second fixing portion 22 and connects to the first fixing portion 21. The connecting portion 23 and the first fixing portion 21 enclose a relief groove 220 to facilitate the snap connection between the first fixing portion 21 and the product to be tested. The relief groove 220 provides clearance for the product to be tested. A part of the product to be tested is snap-connected to the relief groove 220, and then positioned and fixed through the bump 210 on the first fixing portion 21 and the positioning groove of the product to be tested, strengthening the connection between the fixing member 20 and the product to be tested and reducing the wobbling between the two.

[0077] Optionally, the first fixing portion 21, the second fixing portion 22, and the connecting portion 23 are integrally formed. This can effectively enhance the overall strength of the fixing member 20, thereby avoiding wobbling between the fixing member 20 and the product to be tested and between the fixing member 20 and the support member 10, and further avoiding resonance among the three.

[0078] In an embodiment of the present application, as Figure 8 shown, the vibration test fixture further includes a base 40. A plurality of mounting holes 400 are formed in the base 40, and the plurality of mounting holes 400 penetrate through the base 40. The mounting holes 400 are used for setting screws to fix the connection among the support member 10, the base 40, and the test bench.

[0079] Preferably, the mounting holes 400 located in the middle of the base 40 are used for setting screws to connect the support member 10, and the mounting holes 400 located on both sides of the base 40 are used for setting screws to connect the test bench. Thereby, the connection strength among the support member 10, the base 40, and the test bench can be strengthened, thus avoiding wobbling and resonance.

[0080] A second aspect of the embodiments of the present application provides a vibration test device, including a test bench and at least one vibration test fixture as described above. The vibration test fixture is disposed on the test bench. Thus, vibration tests can be performed on at least one product to be tested as needed.
