Description

Technical Field

[0001] This application relates to the field of torque testing equipment technology, and more particularly to a torque testing device for an adapter. Background Technology

[0002] As adapters become increasingly thinner and lighter, they are often equipped with flip covers. These covers conceal the components to be protected when closed, while also providing a gap when open to prevent the edge of the component from getting too close to the edge of the adapter, thus ensuring protection for the component as well. Taking a pin as an example, the open cover provides a gap to prevent the edge of the pin from getting too close to the edge of the adapter, keeping the creepage distance at the pin base within a safe operating range.

[0003] When the flip cover provides protection for the component to be protected, it necessitates a robust design for the connection between the flip cover and the adapter body. At a basic level, the connection should not be damaged when subjected to full force by hand. Therefore, the connection strength between the flip cover and the adapter body needs to be tested. Summary of the Invention

[0004] This application provides a torque testing device for an adapter, which can solve the problem of difficulty in testing the connection strength between the adapter's flip cover and the main body.

[0005] This application provides a torque testing device for an adapter, the adapter including a main body and a flip cover, the flip cover being rotatably connected to the main body about a first direction, the torque testing device being used to test the torsional strength at the connection between the flip cover and the main body of the adapter, the torque testing device including:

[0006] The first fastener is used to install one of the main body and the flip cover;

[0007] The second fastener is used to install the main body and another of the flip covers;

[0008] A drive mechanism is connected to the first fixing member and is used to enable the first fixing member to rotate about a second direction relative to the second fixing member, wherein the second direction is set at an angle to the first direction.

[0009] Based on the torque testing device for the adapter in the embodiments of this application, the torque testing device is set to drive the flip cover and the main body of the adapter to twist in a second direction that forms an angle with the first direction of the flip cover rotating relative to the main body. This simulates the most convenient way for the user to apply force to the flip cover and the main body of the adapter, so as to test the torsional strength at the connection between the flip cover and the main body, so that the measured torsional strength at the connection between the flip cover and the main body is more accurate and reliable.

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0028] The inventor found that by pushing, pulling, pressing, twisting, dropping and other forms of damage to the flip cover of the adapter, from the results, twisting is the most powerful way of destruction, which can fully examine the bonding strength of each part, and at the same time, twisting is also the most convenient way for users to exert force with bare hands, and after the torque reaches a certain value, it is basically guaranteed that other force exertion methods are more difficult to achieve destruction. Based on this, the present application provides a torque testing device for an adapter, which tests the torsional strength of the connection between the flip cover and the main body of the adapter.

[0029] As shown in Figure 1 , it is a structure schematic diagram of an adapter 200 of an embodiment of the present application installed on a torque testing device 100. Among them, the flip cover 210 of the adapter 200 is rotatably connected with the main body 220 around the first direction A, so as to cover or expose the protected parts of the adapter 200 when the flip cover 210 and the main body 220 rotate around the first direction A, for example, the protected parts of the adapter 200 can include the pin 230, the data interface, etc. The number of flip covers 210 of the adapter 200 can be one or more, for example, the number of flip covers 210 of the adapter can be two, the two flip covers 210 are oppositely arranged along the direction perpendicular to the first direction A, and both of the two flip covers 210 rotate relative to the main body 220 around the first direction A as the central axis to expose or cover the protected parts.

[0030] As shown in Figure 1 and Figure 2As shown, the torque testing device 100 comprises a first fixing member 110, a second fixing member 120 and a driving mechanism 130. The first fixing member 110 is used to mount one of the main body 220 and the flip cover 210 of the adapter 200, and the second fixing member 120 is used to mount the other of the main body 220 and the flip cover 210 of the adapter 200. The driving mechanism 130 is connected to the first fixing member 110 and is used to rotate the first fixing member 110 relative to the second fixing member 120 about the second direction B, which is arranged at an angle to the first direction A. By controlling the driving mechanism 130 to operate, the first fixing member 110 is driven to rotate the flip cover 210 relative to the main body 220, so as to test the torsional strength of the connection between the flip cover 210 and the main body 220.

[0031] When the first fixing member 110 rotates relative to the second fixing member 120 about the second direction B, the first fixing member 110 can act on one end of the main body 220 or the flip cover 210 connected thereto, so as to drive the main body 220 or the flip cover 210 to rotate about the other end thereof as the center. Alternatively, the first fixing member 110 can act on the main body 220 or the flip cover 210 connected thereto, so as to drive the main body 220 or the flip cover 210 to rotate about the center axis thereof as the center axis, for example, as shown in Figure 1 As shown, the first fixing member 110 drives the flip cover 210 to rotate about the center axis of the flip cover 210 as the center axis.

[0032] The flip cover 210 of the adapter 200 has a closed state and an open state. In the open state, the flip cover 210 exposes the protected member provided on the main body 220. In the closed state, the flip cover 210 covers the protected member provided on the main body 220. By controlling the main body 220 and the flip cover 210 to rotate about the first direction A, the flip cover 210 can be switched between the closed state and the open state.

[0033] When the protected member of the adapter 200 is recessed in the main body 220, for example, the protected member is a data interface, the flip cover 210 can be in the closed state or the open state, and one of the flip cover 210 and the main body 220 is mounted on the first fixing member 110, and the other is mounted on the second fixing member 120, so as to test the torsional strength of the connection between the flip cover 210 and the main body 220.

[0034] When the protected member of the adapter 200 is protruded from the main body 220, for example, the protected member is the pin 230, the flip cover 210 is in the open state, and one of the flip cover 210 and the main body 220 is mounted on the first fixing member 110, and the other is mounted on the second fixing member 120, so as to test the torsional strength of the flip cover 210 and the main body 220 in the open state, so as to prevent the protruded protected member from affecting the test in the activity path of the flip cover 210.

[0035] When the first fixing member 110 and the second fixing member 120 drive the flip cover 210 and the main body 220 to rotate respectively, the flip cover 210 and the main body 220 have independent rotating areas respectively, and the flip cover 210 and the main body 220 do not interfere with each other when moving in the rotating areas respectively. When the flip cover 210 is in the open state and the torsional strength test is performed, the flip angle of the flip cover 210 should be controlled to adjust the rotating area of the flip cover 210, so that the rotating area of the flip cover 210 is spaced apart from the to-be-protected member provided on the main body 220, to prevent the to-be-protected member from affecting the movement of the flip cover 210.

[0036] In some exemplary embodiments, one of the flip cover 210 and the main body 220 is fixedly installed on the first fixing member 110, and the other is fixedly installed on the second fixing member 120, so that the second fixing member 120 is used to limit the position of one of the flip cover 210 and the main body 220, and the first fixing member 110 is used to drive the other of the flip cover 210 and the main body 220 to move, so as to test the torsional strength of the flip cover 210 and the main body 220. For example, the first fixing member 110 and the second fixing member 120 can be clamping claws, and are used to clamp the corresponding flip cover 210 and main body 220; or the first fixing member 110 and the second fixing member 120 can have clamping parts, and are used to clamp the corresponding flip cover 210 and main body 220.

[0037] In some exemplary embodiments, the first fixing member 110 has a first material placing area, and the second fixing member 120 has a second material placing area, the first material placing area is used to accommodate one of the flip cover 210 and the main body 220, and the second material placing area is used to accommodate the other of the flip cover 210 and the main body 220. The flip cover 210 and the main body 220 can move in the corresponding first material placing area and the second material placing area, so that the first fixing member 110 and the second fixing member 120 can be used to install main bodies 220 and flip covers 210 of different specifications.

[0038] Optionally, as Figure 2 and Figure 3As shown, the first fixing member 110 is provided with a first accommodating groove 110a extending along the second direction B, and the first fixing member 110 is used to form the wall surface of the first accommodating groove 110a and also define the range of the first discharging area; and the second discharging area of the second fixing member 120 is provided with a second accommodating groove 120a extending along the third direction C, and the third direction C is arranged at an angle with respect to the first direction A and the second direction B, and the second fixing member 120 is used to form the wall surface of the second accommodating groove 120a and also define the range of the second discharging area. The first accommodating groove 110a is used to mount one of the main body 220 and the flip cover 210, and the second accommodating groove 120a is used to mount the other one of the main body 220 and the flip cover 210. Taking the first accommodating groove 110a of the first fixing member 110 as an example, when the shape of the first accommodating groove 110a matches the shape of the flip cover 210 and the shape of the second accommodating groove 120a matches the shape of the main body 220, the driving element drives the first fixing member 110 to rotate around the second direction B, and the first fixing member 110 abuts against the flip cover 210 to test the torsional strength of the connection between the flip cover 210 and the main body 220; or when the wall surface of the first accommodating groove 110a of the first fixing member 110 is arranged at an interval with respect to the flip cover 210 and the shape of the second accommodating groove 120a matches the shape of the main body 220, the driving element drives the first fixing member 110 to rotate around the second direction B until the first fixing member 110 contacts the surface of the flip cover 210, and then the first fixing member 110 abuts against the flip cover 210 to test the torsional strength of the connection between the flip cover 210 and the main body 220.

[0039] In some exemplary embodiments, the second fixing member 120 can be provided with a bearing part 121 and a cover part 122, the bearing part 121 is detachably connected with the cover part 122, and the second accommodating groove 120a is defined between the bearing part 121 and the cover part 122. When the torsional strength test of the flip cover 210 and the main body 220 is performed, one of the flip cover 210 and the main body 220 is placed in the bearing part 121, the cover part 122 partially covers the flip cover 210 or the main body 220 placed in the bearing part 121, and the cover part 122 is fixed to the bearing part 121, and then the first fixing member 110 is controlled to rotate around the second direction B after the other one of the flip cover 210 and the main body 220 is mounted in the first fixing member 110, so as to test the torsional strength of the connection between the flip cover 210 and the main body 220.

[0040] Optionally, the first accommodating groove 110a extends through the first fixing member 110 along the first direction A, so that one of the flip cover 210 and the main body 220 can be directly moved along the first direction A to be placed in the bearing part 121, and the other one of the flip cover 210 and the main body 220 can be simultaneously moved into the first accommodating groove 110a, thereby facilitating the quick and efficient mounting of the adapter 200 to the torque test device 100.

[0041] Optionally, one of the bearing part 121 and the cover part 122 is provided with a guide groove 121a extending along the third direction C, and the other is provided with a guide protrusion 1223 arranged in the guide groove 121a. The guide protrusion 1223 is slidably arranged in the guide groove 121a. The guide groove 121a and the guide protrusion 1223 are matched with each other, and the cover part 122 can be guided to move along the third direction C to be aligned with the bearing part 121, so as to define the second accommodating groove 120a, and improve the mounting efficiency of the cover part 122 on the bearing part 121.

[0042] Optionally, the bearing part 121 and the cover part 122 are respectively provided with threaded holes, the threaded holes are arranged along a direction at an angle to the third direction C, and the threaded hole of the bearing part 121 corresponds to the threaded hole of the cover part 122. When the cover part 122 is assembled, the cover part 122 is moved along the third direction C, and when the threaded holes of the cover part 122 and the bearing part 121 are accurately aligned, a fixing screw is arranged and locked in the threaded hole, so as to fix the cover part 122 on the bearing part 121, and define the second accommodating groove 120a between the cover part 122 and the bearing part 121.

[0043] When the cover part 122 is provided with the guide protrusion 1223, the threaded hole of the cover part 122 can be arranged at the guide protrusion 1223.

[0044] Optionally, as shown in Figure 2 and Figure 4 , the cover part 122 comprises a main plate 1221 and at least one standing plate 1222 arranged on the main plate 1221. The standing plate 1222 is arranged at an angle to the main plate 1221. The surfaces of the main plate 1221, the standing plate 1222 and the bearing part 121 define the second accommodating groove 120a. The guide protrusion 1223 or the guide groove 121a is arranged on the standing plate 1222. The number of the standing plate 1222 can be one. In this case, the bearing part 121 is provided with a pre-installation surface 121a and a side standing surface 121b connected to the pre-installation surface 121a. When the cover part 122 is mounted on the bearing part 121, the main plate 1221 of the cover part 122 is arranged opposite to the pre-installation surface 121a of the bearing part 121 along the second direction B, and the standing plate 1222 of the cover part 122 is arranged opposite to the side standing surface 121b of the bearing part 121 along the first direction A, so as to define the second accommodating groove 120a. The number of the standing plate 1222 can also be two. The two standing plates 1222 are arranged on the same side of the main plate 1221. When the cover part 122 is mounted on the bearing part 121, the surface of the bearing part 121 facing the main plate 1221, the standing plate 1222 and the two main plates 1221 together define the second accommodating groove 120a.

[0045] When the adapter 200 is installed in the torque testing device 100, the adapter 200 is accommodated in the second accommodating groove 120a, and the part of the structure at least partially protrudes from the second accommodating groove 120a, so that the connecting part of the flip cover 210 and the main body 220 is adjacent to the first fixing member 110, so as to reserve space for the torsional strength test, and the second fixing member 120 avoids the first fixing member 110 and avoids the flip cover 210 or the main body 220 connected with the first fixing member 110.

[0046] Optionally, the second accommodating groove 120a penetrates the second fixing member 120 in the third direction C, so as to adjust the position of the adapter 200 installed in the torque testing device 100. For example, when the flip cover 210 is in the open state, the main body 220 of the adapter 200 is arranged in the second accommodating groove 120a, and the second accommodating groove 120a penetrates the second fixing member 120, so as to conveniently adjust the position of the main body 220 in the third direction C.

[0047] The torque testing device 100 further comprises a base 140, and the base 140 comprises a first mounting part 141 and a second mounting part 142, and the second mounting part 142 and the second fixing member 120 are arranged on the same side of the first mounting part 141. The second mounting part 142 can be integrally arranged with the first mounting part 141.

[0048] When the adapter 200 comprises two flip covers 210, the second mounting part 142 has a third accommodating groove 140a which is arranged towards the first fixing member 110, extends to the surface of the second mounting part 142 in the first direction A and away from the first mounting part 141, and is used for mounting one of the flip covers 210, and the first accommodating groove 110a is used for mounting the other flip cover 210. When the torsional strength test of the flip cover 210 and the main body 220 is performed, the adapter 200 can be translated in the first direction A, so that the two flip covers 210 of the adapter 200 can be directly inserted into the corresponding first accommodating groove 110a and third accommodating groove 140a. Optionally, the bearing part 121 is arranged to bear the surface of the adapter 200, which is a plane, and the main body 220 of the adapter 200 can be attached to the plane and translated in the first direction A, so that after the two flip covers 210 of the adapter 200 are respectively inserted into the first accommodating groove 110a and the third accommodating groove 140a, the main body 220 of the adapter 200 is supported on the bearing part 121 and is no longer displaced in the second direction B, thereby improving the installation stability and efficiency of the adapter 200.

[0049] When the adapter 200 comprises two flip covers 210, the two flip covers 210 of the adapter 200 can be adjusted to be in the open state, so as to prevent the two flip covers 210 from interfering with each other during the torque test. For example, Figure 1As shown, the opening state of the two flip covers 210 can be adjusted to a state in which the flip covers 210 are rotated 90 degrees around the first direction A as the central axis from the closed state of the flip covers 210, so that after the torsion test of the connection between one of the flip covers 210 and the main body 220 is completed, the adapter 200 can be directly rotated 180 degrees around the third direction C to test the torsion of the connection between the other flip cover 210 and the main body 220.

[0050] The torque testing device 100 further comprises a control mechanism 170, which is electrically connected with the driving mechanism 130 to control the operation state of the driving mechanism 130, and further control the activity state of the first fixing member 110.

[0051] In the embodiment of the present application, when the torsion strength of the flip cover 210 and the main body 220 is tested, the control mechanism 170 drives the first fixing member 110 to rotate the flip cover 210 or the main body 220 connected therewith around the second direction B as the central axis, and the rotation is in the clockwise direction and the counterclockwise direction to test the torsion strength of the flip cover 210 and the main body 220 in the two directions.

[0052] The torque testing device 100 further comprises a limit switch 152 and a limiting member 151, the limiting member 151 is connected with the driving mechanism 130, and when the driving mechanism 130 operates, the driving mechanism 130 drives the first fixing member 110 and the limiting member 151 to rotate around the second direction B, wherein the limiting member 151 rotates within a preset working area around the second direction B. The limit switch 152 is electrically connected with the control mechanism 170, and the limit switch 152 is arranged corresponding to the limiting member 151, when the limiting member 151 is driven by the driving mechanism 130 to exceed the preset working area, the limiting member 151 can contact the limit switch 152 to trigger the limit switch 152 to generate a switch signal sent to the control mechanism 170, and the control mechanism 170 controls the driving mechanism 130 to drive the first fixing member 110 to stop rotating or change the rotating direction of the first fixing member 110. For example, when the connection structure between the flip cover 210 and the main body 220 is broken, the limiting member 151 is driven by the driving mechanism 130 to contact the limit switch 152 to trigger the limit switch 152 to generate a switch signal sent to the control mechanism 170, and the control mechanism 170 controls the driving mechanism 130 to drive the first fixing member 110 to stop rotating, thereby preventing the driving mechanism 130 from driving the limiting member 151 to rotate excessively; or when the torsion value of the flip cover 210 or the main body 220 connected with the first fixing member 110 exceeds the preset torsion angle, the limiting member 151 contacts the limit switch 152 to trigger the limit switch 152 to generate a switch signal sent to the control mechanism 170, and the control mechanism 170 controls the driving mechanism 130 to drive the first fixing member 110 to stop rotating or change the rotating direction of the first fixing member 110.

[0053] Optionally, the control mechanism 170 comprises a control board 171, the limit switch 152 is electrically connected with the control board 171, and the control board 171 is electrically connected with the driving mechanism 130. When the control board 171 receives the switch signal transmitted by the limit switch 152, the control board 171 controls the operation state of the driving mechanism 130.

[0054] Optionally, the length direction of the limiting piece 151 is perpendicular to the second direction B, so that when the driving mechanism 130 drives the limiting piece 151 to rotate around the second direction B beyond the preset working area, the limiting piece 151 can accurately contact the limit switch 152. For example, the limiting piece 151 can be a bar-shaped rod, and the length direction of the bar-shaped rod is perpendicular to the second direction B. The shape of the limiting piece 151 is not limited in the present application, and can be selected according to actual needs.

[0055] Optionally, the number of limit switches 152 is two, and the two limit switches 152 are respectively arranged at the two ends of the preset working area of the limiting piece 151, so that when the control mechanism 170 drives the first fixed piece 110 to drive the limiting piece 151 to rotate clockwise or counterclockwise around the second direction B, the two limit switches 152 respectively limit the activity range of the limiting piece 151 in the two activity directions of the limiting piece 151.

[0056] The torque testing device 100 further comprises a torque sensor 161 connected between the driving mechanism 130 and the first fixed piece 110, so as to obtain the torque value when the driving mechanism 130 drives the first fixed piece 110 to rotate around the second direction B. The control mechanism 170 is electrically connected with the torque sensor 161, and the torque sensor 161 also has the function of a transmitter. The torque sensor 161 can transmit the torque value to the control mechanism 170. The control mechanism 170 compares the obtained torque value with the preset torque value, and controls the driving mechanism 130 to stop rotating or change the rotating direction of the first fixed piece 110 when the torque value exceeds the preset torque value. For example, when the torque value obtained by the torque sensor 161 exceeds the preset torque value, the connecting structure between the flip cover 210 and the main body 220 has not been twisted off or twisted to be deformed, and then the control mechanism 170 controls the driving mechanism 130 to stop operating or controls the driving mechanism 130 to drive the first fixed piece 110 to rotate in the opposite direction.

[0057] The preset torque value is obtained by collecting torque values output by the flip cover 210 and the main body 220 of the adapter 200 when a plurality of adult men with similar height and weight act on the flip cover 210 and the main body 220 of the adapter 200 with bare hands, and analyzing the torque values. Optionally, the range of the torque sensor 161 is set to be greater than or equal to 0 N·m and less than or equal to 10 N·m, and the preset torque value is 7 N·m. Specifically, the preset torque value can be obtained by the following method:

[0058] The average torque value output by the flip cover 210 and the main body 220 of the adapter 200 when the adult men with similar height and weight act on the flip cover 210 and the main body 220 of the adapter 200 with bare hands is 3.3 N·m, and the standard deviation is 0.76 N·m, which conforms to the normal distribution rule;

[0059] The average value + 3 times the standard deviation = 3.3 + 3*0.76 = 5.6 N·m;

[0063] Optionally, the rotation speed range of the driving mechanism 130 driving the first fixing member 110 to rotate around the second direction B is greater than or equal to 4.0 revolutions per minute and less than or equal to 5.0 revolutions per minute, and preferably the rotation speed is 4.5 revolutions per minute (27° / second), so that the speed of the driving mechanism 130 driving the first fixing member 110 to rotate conforms to the speed of the human hand acting on the flip cover 210 and the main body 220.

The monitoring module 172 is also used to compare the acquired torque value with the preset torque value, and send the comparison result to the control mainboard 171, so that the control mainboard 171 controls the operation state of the driving mechanism 130. The monitoring module 172 can include a display panel 172 for displaying the acquired torque value to the user.

[0065] Optionally, the control mainboard 171 is electrically connected with the monitoring module 172, and the control mainboard 171 is also electrically connected with the limit switch 152. When one of the torque sensor 160 and the monitoring module 172 fails, the limit switch 152 sends a switch signal to the control mainboard 171 to control the running state of the driving mechanism 130.

[0066] Optionally, the torque testing device further comprises a power supply 180, which is electrically connected with the control mainboard 171 to supply power to the limit switch 152, the torque sensor 161 and the monitoring mechanism 172 through the control mainboard 171.

The transmission shaft 162 is arranged towards the driving shaft 132, and the length direction of the transmission shaft 162 is arranged along the second direction B. The transmission shaft 162 is rigidly connected with the driving shaft 132 through a coupling shaft key 190. The sensor main body 161 is connected to the first fixing part 110 to obtain the torque value of the first fixing part 110 acting on the adapter 200. When the torque testing device further comprises the limiting part 151, the limiting part 151 can be fixed to the sensor main body 161 or fixed to the first fixing part 110.
