For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Please refer to Figures 1 to 7 The utility model discloses a knock vibration test mechanism of an embodiment, including knock subassembly 10, knock subassembly 10 includes knock support 11, rotates and installs knock roller 12 on knock support 11, installs knock drive part 13 for driving knock roller 12 rotation on knock support 11, rotates and installs knock piece 14 on knock support 11, and the rotation piece 15 for driving knock piece 14 to knock the product 70 on the fixture 60 is sleeved on knock roller 12, and one end of knock piece 14 cooperates with rotation piece 15, and the other end is used to knock the test of product 70. In the embodiment, the product 70 is an adapter.

[0028] The working principle of the knock vibration test mechanism of the utility model is as follows: when the test starts, the knock drive part 13 starts to work; it provides power for the knock roller 12, so that the knock roller 12 starts to rotate on the knock support 11; the rotation piece 15 sleeved on the knock roller 12 will rotate together with the knock roller 12; since the rotation piece 15 cooperates with one end of the knock piece 14, when the rotation piece 15 rotates, it will push the knock piece 14; for example, the rotation piece 15 can be an eccentric wheel structure; when the eccentric wheel rotates with the knock roller 12, the eccentric part of the eccentric wheel will periodically push the knock piece 14; the design of such an eccentric wheel can convert the rotary motion into the reciprocating motion of the knock piece 14; the other end of the knock piece 14 is used to knock the product 70 on the fixture 60; under the drive of the rotation piece 15, the knock piece 14 will knock the product 70 according to a certain frequency and force; through such knock vibration test, the structural strength of the shell, the installation firmness of the parts and the like can be detected.

[0029] Compared with the prior art, the knocking vibration test mechanism can find whether the installation of the parts is firm, such as whether the screws are loose, whether the buckles are tight and the like, can detect the firmness of the installation of the parts, avoids the security risks such as the falling of the parts in actual use, has high knocking efficiency and can work stably and continuously, as long as the knocking driving member 13 and other parts are in normal operation, the product 70 can be subjected to uninterrupted knocking test according to the set parameters, manual repeated operation is not needed, and manpower and time are effectively saved; especially for the product 70 which needs to be subjected to a large number of repeated tests, such as small electronic products 70 or automobile parts in batch production, the knocking vibration test mechanism can complete a large number of test tasks in a short time; since the knocking driving member 13 can control the rotation of the knocking roller 12 and indirectly control the movement of the knocking member 14, the frequency and intensity of the knocking can be accurately adjusted.

[0030] Please refer to Figures 2 to 4, the knocking piece 14 comprises a positioning portion 140 rotatably mounted on the knocking support 11, a driving portion 141 arranged at one end of the positioning portion 140 and matched with the rotating piece 15, a knocking portion 142 arranged at the other end of the positioning portion 140 and used for knocking the product 70, and an elastic portion 143 mounted at one end on the knocking support 11 and connected at the other end with the driving portion 141; when the knocking roller 12 drives the rotating piece 15 to move and thus drives the driving portion 141 to move, the driving portion 141 moves away from the elastic portion 143, and the knocking portion 142 moves away from the product 70; when the knocking roller 12 continues to drive the rotating piece 15 to move and thus makes the rotating piece 15 disengage from the driving portion 141, the driving portion 141 moves towards the elastic portion 143, and the knocking portion 142 moves towards the product 70. Specifically, the knocking support 11 is further provided with an infrared sensing piece used for detecting the knocking portion 142, which comprises an emitting portion 80 arranged on the knocking support 11 at one side of the knocking portion 142 and a receiving portion 90 arranged on the knocking support 11 at the other side of the knocking portion 142. When the knocking roller 12 starts to rotate, the rotating piece 15 sleeved on the knocking roller 12 rotates accordingly; since the rotating piece 15 is matched with the driving portion 141 of the knocking piece 14, the movement of the rotating piece 15 drives the driving portion 141 to move; in this process, the driving portion 141 moves away from the elastic portion 143 with the rotating mounting point of the driving portion 141 on the knocking support 11 as the axis; since the knocking portion 142 and the driving portion 141 are on the same positioning portion 140, the knocking portion 142 moves away from the product 70 along with the movement of the driving portion 141; with the continuous rotation of the knocking roller 12, the rotating piece 15 disengages from the driving portion 141; at this time, the elastic potential energy of the elastic portion 143 starts to play a role; since the elastic portion 143 is stretched by the driving portion 141 before, the elastic portion 143 generates a restoring force to make the driving portion 141 rebound towards the elastic portion 143; accordingly, the knocking portion 142 moves towards the product 70 to knock the product 70; this combination of the pushing of the rotating piece 15 and the rebound of the elastic portion 143 enables the knocking portion 142 to generate a reciprocating knocking action; the emitting portion and the receiving portion of the infrared sensing piece are arranged at two sides of the knocking portion 142; in the normal state, the infrared rays emitted by the emitting portion can be received by the receiving portion; when the knocking portion 142 performs the knocking action, the position of the knocking portion 142 changes; when the knocking portion 142 moves away from the product 70, the knocking portion 142 blocks or changes the propagation path of the infrared rays emitted by the emitting portion, so that the infrared signal received by the receiving portion changes, such as the signal strength weakening or being interrupted; when the knocking portion 142 moves towards the product 70 to perform the knocking, the knocking portion 142 also changes the propagation path of the infrared rays, and the receiving portion receives the changed signal again; through the analysis of the change of the infrared signal received by the receiving portion, the movement position and the movement state of the knocking portion 142 can be accurately detected, and thus the information about the knocking frequency and the knocking strength can be obtained, which is used for the accurate monitoring and data recording of the knocking test on the product 70.

[0031] The knocking part 14 further comprises a rotating wheel 144 which is rotatably installed on the driving part 141, and the rotating wheel 144 is matched with the rotating part 15. When the knocking test starts, the knocking roller 12 starts to rotate under the action of the knocking driving part 13; the rotating part 15 sleeved on the knocking roller 12 rotates accordingly; since the rotating wheel 144 is installed on the driving part 141 of the knocking part 14 and matched with the rotating part 15, the circumferential movement of the rotating part 15 first acts on the rotating wheel 144; the driving part 141 moves away from the elastic part 143 under the action of the rotating wheel 144; since the knocking part 142 and the driving part 141 are located on the same positioning part 140, the knocking part 142 also moves away from the product 70 accordingly; with the continuous rotation of the knocking roller 12, the eccentric part of the rotating part 15 gradually moves away from the rotating wheel 144; at this time, the pushing force of the rotating wheel 144 from the rotating part 15 disappears; the elastic force of the elastic part 143 starts to act, and the driving part 141 moves towards the elastic part 143; the movement of the driving part 141 makes the knocking part 142 move towards the product 70, so as to knock the product 70; when the knocking roller 12 rotates again to make the eccentric part of the rotating part 15 contact the rotating wheel 144 again, the above process is repeated, so as to realize the periodic knocking of the knocking part 142 to the product 70; through the cooperation of the rotating wheel 144 and the rotating part 15, the knocking action is more stable and reliable, and the frequency and strength of the knocking can be accurately controlled by adjusting the size, shape and other parameters of the rotating wheel 144 and the rotating part 15.

[0032] The rotating member 15 comprises a fixed ring 150 sleeved on the knocking roller 12, and a protruding part 151 extending outward from one side of the fixed ring 150 and used for cooperating with the rotating wheel 144. When the test starts, the knocking driving member 13 drives the knocking roller 12 to rotate; since the fixed ring 150 is sleeved on the knocking roller 12, the rotation of the knocking roller 12 will drive the fixed ring 150 to rotate synchronously; this connection mode ensures that the power is stably transmitted from the knocking roller 12 to the fixed ring 150; when the fixed ring 150 rotates with the knocking roller 12, the protruding part 151 will make a circular motion around the axis of the knocking roller 12; when the protruding part 151 contacts the rotating wheel 144, a force will be applied to the rotating wheel 144; since the rotating wheel 144 is installed on the driving part 141 of the knocking member 14, the force will drive the rotating wheel 144 to rotate around its own axis, and through the connection relationship between the rotating wheel 144 and the driving part 141, the driving part 141 is driven to rotate around the mounting point thereof on the knocking support 11; under the pushing of the protruding part 151, the driving part 141 drives the knocking part 142 to move away from the product 70; with the continuous rotation of the fixed ring 150, the protruding part 151 will leave the rotating wheel 144, at this time, the elastic force of the elastic part 143 makes the driving part 141 rebound, and drives the knocking part 142 to move towards the product 70, and knocks the product 70; when the fixed ring 150 rotates again, the protruding part 151 will contact the rotating wheel 144 again, and the pushing process described above is repeated, so that the knocking part 142 knocks the product 70 at a certain period according to the rotation frequency of the fixed ring 150; by adjusting the shape and size of the protruding part 151 on the fixed ring 150 and the rotation speed of the knocking roller 12 and other parameters, the contact frequency and contact force of the protruding part 151 and the rotating wheel 144 can be changed, and then the knocking frequency and force of the knocking part 142 on the product 70 can be accurately controlled.

[0033] Please refer to Figure 5 and Figure 6 , the knocking vibration test mechanism further comprises a detection assembly 20, the detection assembly 20 comprises a detection support 21, a pushing member installed on the detection support 21, and an electrical detection member installed on the detection support 21 opposite to the pushing member and used for electrical detection of the jig 60; the knocking support 11 is installed on the detection support 21. The knocking support 11 is installed on the detection support 21, so that the knocking vibration test mechanism and the detection assembly 20 form an integral whole; this ensures that other detection operations can be conveniently performed while the knocking vibration test is being performed; the pushing member is installed on the detection support 21, and when the jig 60 needs to be detected, the electrical detection member is installed on the detection support 21 opposite to the pushing member, which can send a detection signal to the circuit inside the product 70 through the circuit interface on the jig 60, and then receive a feedback signal to determine whether the circuit is normal; the circuit detection can be performed through the electrical detection member before and after the knocking vibration test, so as to determine whether the knocking vibration has an influence on the circuit performance of the product 70.

[0034] The pushing member includes a driving part 22 mounted on the detection support 21, the driving part 22 further includes a driving rod, the pushing member further includes a pushing plate 23 mounted on the driving rod and a rubber pad 24 on the pushing plate 23, the rubber pad 24 is arranged towards the side of the electrical contact detection member. When the detection system starts the detection process of the fixture 60, the driving part 22 mounted on the detection support 21 drives the driving rod to perform the extension and retraction movement; the pushing plate 23 mounted on the driving rod moves with the movement of the driving rod; when the driving rod extends, the pushing plate 23 moves towards the direction of the electrical contact detection member; the rubber pad 24 on the pushing plate 23 plays a role of buffering and protection; the rubber pad 24 is arranged towards the side of the electrical contact detection member, when the pushing plate 23 contacts the fixture 60, the rubber pad 24 first contacts the fixture 60; because the rubber has good elasticity, it can buffer the pressure applied by the pushing plate 23 to the fixture 60, preventing damage to the fixture 60 due to excessive pressure; at the same time, the rubber pad 24 can also increase the friction force; when the pushing plate 23 pushes the fixture 60 to contact the electrical contact detection member, the friction force between the rubber pad 24 and the fixture 60 can help the fixture 60 to maintain a stable position, ensuring good contact between the fixture 60 and the electrical contact detection member, thereby improving the accuracy of the electrical contact detection; for example, in a test environment with vibration or slight shaking, the friction force of the rubber pad 24 can prevent the fixture 60 from moving, so that the electrical contact detection can be smoothly performed.

[0035] The electrical contact detection member includes a detection plate 25 mounted on the detection support 21, a detection socket 26 mounted on the detection plate 25 for plugging the fixture 60, and a positioning column 27 mounted on the detection plate 25 for positioning the fixture 60. When the fixture 60 is pushed by the pushing member to approach the electrical contact detection member, the positioning column 27 plays a role of guiding and positioning; the detection socket 26 is mounted on the detection plate 25, when the fixture 60 is properly positioned, the plug on the fixture 60 is inserted into the detection socket 26; the detection socket 26 has conductive contacts corresponding to the plug inside; these conductive contacts are connected with the detection circuit, when the plug is inserted, a complete circuit path is formed; the detection circuit can send specific electrical signals to the circuit inside the fixture 60 through the detection socket 26; the detection plate 25 serves as a mounting base, bearing the detection socket 26 and the positioning column 27; it not only provides physical support, but also plays a role of circuit connection and signal transmission; the detection plate 25 usually has wiring inside, connecting the conductive contacts of the detection socket 26 with the external detection equipment; these wirings can ensure stable transmission of electrical signals, preventing signal interference and attenuation; at the same time, the material and design of the detection plate 25 also consider electromagnetic compatibility, avoiding the influence of external electromagnetic interference on the detection signal, ensuring the accuracy and reliability of the electrical contact detection.

[0036] Please refer to Figure 2, the knock vibration testing mechanism further comprises an up-down driving assembly 30 installed on the detection support 21 for driving the knock assembly 10 to move up and down, and the up-down driving assembly 30 further comprises an up-down pushing rod 31, and the knock support 11 is installed on the up-down pushing rod 31. Since the knock support 11 is installed on the up-down pushing rod 31, when the up-down pushing rod 31 moves up and down, the knock support 11 also moves up and down accordingly; such up-down movement can achieve multiple functions; for example, when the knock vibration test is performed on products 70 or jigs 60 of different heights, the height of the knock assembly 10 can be adjusted so that the knocking part 14 can accurately act on the target test position of the product 70; if the product 70 is relatively high, the knock support 11 is raised by the up-down driving assembly 30 to ensure that the knocking part 142 can contact the appropriate part of the product 70 for effective test; on the contrary, if the product 70 is relatively low, the knock support 11 is lowered to avoid that the knocking part 142 is too high to normally test; in addition, during the test, the height of the knock assembly 10 can also be dynamically adjusted by the up-down driving assembly 30 to simulate the situation that the product 70 is subjected to knock vibration at different height positions, thereby increasing the comprehensiveness and flexibility of the test.

[0037] Please refer to Figure 7 , the knock vibration testing mechanism further comprises a conveying assembly 40 installed on the detection support 21 for conveying the jig 60, and the conveying assembly 40 comprises a conveying part 41 installed on the detection support 21 and a conveying driving part 42 installed on the detection support 21 for driving the conveying part 41 to move. The conveying part 41 is installed on the detection support 21, and its main function is to carry and convey the jig 60; the conveying part 41 can be in various forms such as a conveying belt, a conveying roller or a conveying chain; taking the conveying belt as an example, when the conveying driving part 42 drives the conveying belt to move, the jig 60 is placed on the conveying belt; due to the friction between the conveying belt and the jig 60, the jig 60 will move together with the conveying belt; the surface material and texture design of the conveying belt can enhance the friction between the conveying belt and the jig 60 to ensure that the jig 60 will not easily slide during the conveying process; if it is a conveying roller, the jig 60 is placed on the roller, and the rotation of the roller drives the jig 60 to move; the distance and height between adjacent rollers need to be designed according to the size and shape of the jig 60 to ensure the stability of the jig 60 during the rolling process; the conveying chain drives the jig 60 through the connecting parts on the chain, and its working principle is similar to that of the conveying belt, both of which realize the position movement of the jig 60 through power transmission, so as to convey the jig 60 to the designated test position, such as the position below the knock assembly 10 or the position near the power-on detection part for corresponding test.

[0038] Please refer to Figure 5 and Figure 6The knock vibration test mechanism further comprises a jacking assembly 50 installed on the detection support 21, the jacking assembly 50 comprising a fixing frame 51 installed on the detection support 21, a jacking driving part 52 installed on the fixing frame 51; the jacking driving part 52 further comprises a jacking rod 53, and the jacking assembly 50 further comprises a bearing frame 54 installed on the jacking rod 53 for bearing the jig 60. The bearing frame 54 is installed on the jacking rod 53, and its main function is to bear the jig 60; when the jacking rod 53 moves upward under the action of the jacking driving part 52, the bearing frame 54 also rises; there can be some positioning devices on the surface of the flat plate, such as positioning pins or positioning grooves, for ensuring the accurate position of the jig 60 on the bearing frame 54; when the bearing frame 54 rises to a specified height, it can jacking the jig 60 to a suitable position, facilitating subsequent test operations; for example, jacking the jig 60 to a height corresponding to the knocking part 142 of the knocking assembly 10, so that the knock vibration test can accurately act on the product 70 on the jig 60; or jacking the jig 60 to a height suitable for the power-on detection part, facilitating power-on detection and other operations; at the same time, after the test is completed, the jacking rod 53 descends, and the bearing frame 54 can put the jig 60 back to the original position or transfer it to the next working area.

[0039] The above only expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, and the present application also intends to include these changes and modifications.
