[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See also Figures 1 to 6 As shown, the present invention provides a motor test quick connector, including a mounting frame, a clamping assembly and a test connector 12, the test connector 12 is arranged on the mounting frame, the clamping assembly includes a clamping part and a driving part 4, the clamping part is arranged on the mounting frame, the driving part 4 is arranged in the mounting frame, and the clamping part is drivingly connected to the driving part 4.

[0029] In the above technical scheme, the mounting frame provides a stable mounting platform for the test connector 12 and the clamping assembly, which plays a role of support and positioning. The test connector 12 is the core component of the quick connector, which is used to directly connect to the test port of the motor to transmit the current, signal or data required for the test. The clamping part is used to clamp and fix the motor to prevent the motor from loosening or falling off during the test, thereby ensuring the safety of the test. The driving part 4 is located inside the mounting frame and is driven and connected to the clamping part through a transmission mechanism. The driving part 4 can adopt an electric, pneumatic or hydraulic drive device to provide power for the clamping and loosening action of the clamping part. The motor test quick connector provided by the present invention realizes the quick connection of the motor by setting the clamping assembly and the test connector 12, so that the operator does not need to frequently disassemble and install screws or other fixings, which greatly shortens the preparation and disassembly time of the motor test, improves the efficiency of production or R&D testing, and reduces the labor intensity of the operator.

[0030] In one embodiment of the present invention, the mounting frame includes a first mounting frame 1, which is provided with a first mounting hole, the first mounting hole is connected to the interior of the first mounting frame 1, and the test connector 12 is provided in the first mounting frame 1 and extends out of the first mounting hole.

[0031] In the above technical solution, the first mounting frame 1 is used to install the test connector 12. The first mounting hole serves as a passage for the test connector 12 to extend, so that the test connector 12 installed in the first mounting frame 1 can be connected to the test port of the external motor. The test connector 12 is a key component for electrically or mechanically connecting with the motor test port, and is responsible for transmitting the current, signal or data required for the test.

[0032] In one embodiment of the present invention, a limiting mechanism is also provided on the first mounting frame 1, and the limiting mechanism includes a locking portion 13. A second mounting hole is opened on the side wall of the first mounting frame 1, and the locking portion 13 is inserted into the second mounting hole. A positioning hole 121 is provided on the test connector 12, and the locking portion 13 extends into one end of the first mounting frame 1 and is inserted into the positioning hole 121.

[0033] In the above technical solution, the positioning hole 121 is provided on the test connector 12, one end of the locking portion 13 is passed through the second mounting hole of the first mounting frame 1, and the other end is inserted into the positioning hole 121. The positioning hole 121 cooperates with the locking portion 13 to form a mechanical lock on the test connector 12, ensuring that the test connector 12 will not loosen or fall off due to external force in the connected state, thereby enhancing the reliability of the connection. The second mounting hole is provided on the side wall of the first mounting frame 1, and is used to pass the locking portion 13 and axially guide and circumferentially limit the locking portion 13. The test connector 12 can be unlocked by pulling the locking portion 13 outward to make the locking portion 13 disengage from the positioning hole 121. By providing the locking portion 13, the convenience of disassembly of the test connector 12 can be significantly improved, and the difficulty of maintenance or replacement of the test connector 12 can be reduced.

[0034] In one embodiment of the present invention, the limiting mechanism also includes a reset component 14, a accommodating cavity 11 is provided in the side wall of the first mounting frame 1, the second mounting hole is connected to the accommodating cavity 11, the reset component 14 is provided in the accommodating cavity 11, the reset component 14 includes a limiting flange 141 and an elastic member 142, the limiting flange 141 is fixed on the locking portion 13, the elastic member 142 is sleeved on the locking portion 13, and the elastic member 142 can apply an elastic force to the limiting flange 141 toward the test connector 12.

[0035] In the above technical solution, the limiting flange 141 can prevent the locking part 13 from excessively moving out of the second mounting hole and causing the connection to fail. An elastic member 142 such as a spring is sleeved on the locking part 13, and its function is to apply an elastic force toward the test connector 12 to the limiting flange 141, so that after the locking part 13 is disconnected from the test connector 12 under the action of tension, the locking part 13 can be pushed back to the initial position under the elastic force of the elastic member 142, ready for the next connection action, reducing the steps of manual reset, thereby improving the operation efficiency. The accommodating chamber 11 is arranged in the side wall of the first mounting frame 1, and its main function is to provide an installation space for the reset assembly 14.

[0036] In one embodiment of the present invention, the mounting frame also includes a second mounting frame 2, which is connected to the first mounting frame 1, and a clamping portion is arranged at the end of the second mounting frame 2. An installation channel 21 is arranged inside the second mounting frame 2. The clamping assembly also includes a transmission portion, which is arranged in the installation channel 21. The clamping portion includes a first clamping section 31. The first end of the first clamping section 31 extends into the installation channel 21. The first clamping section 31 can slide along the installation channel 21. One end of the transmission portion is connected to the first clamping section 31, and the other end of the transmission portion is drivingly connected to the driving portion 4.

[0037] In the above technical solution, the second mounting frame 2 is used to provide installation space for the clamping assembly and the transmission part. The mounting channel 21 is used to accommodate the clamping part and the transmission part, wherein the mounting channel 21 supports and fixes the clamping part, and at the same time, the first clamping section 31 of the clamping part is axially limited so that the first clamping section 31 can only slide along the mounting channel 21, thereby ensuring the accuracy and stability of the clamping action. The transmission part is used to transmit the output power of the driving part 4 to the first clamping section 31, driving the first clamping section 31 to slide along the mounting channel 21, thereby clamping or releasing the motor.

[0038] In one embodiment of the present invention, the clamping portion also includes a second clamping section 32 and a third clamping section 33, the first end of the second clamping section 32 is connected to one end of the first clamping section 31 extending out of the mounting channel 21, the second clamping section 32 is perpendicular to the first clamping section 31, one end of the third clamping section 33 is connected to the second end of the second clamping section 32, the third clamping section 33 is perpendicular to the second clamping section 32 and is arranged opposite to the first clamping section 31, the first clamping section 31, the second clamping section 32 and the third clamping section 33 are located in the same plane, and the enclosed area formed by the first clamping section 31, the second clamping section 32 and the third clamping section 33 is the clamping area.

[0039] In the above technical solution, the first clamping section 31, the second clamping section 32 and the third clamping section 33 together form a clamping frame to firmly clamp the electrode, thereby ensuring the stability and safety of the motor during the test process.

[0040] In one embodiment of the present invention, a stopper 19 is provided on the transmission part, a stopper groove is provided on the second mounting frame 2, the stopper groove is connected to the mounting channel 21, and one end of the stopper 19 away from the transmission part is provided in the stopper groove.

[0041] In the above technical solution, the stop member 19 cooperates with the stop groove to limit the transmission part, so as to prevent the transmission part from being subjected to the axial force of the bidirectional screw during the transmission process, causing the transmission part to move in a direction away from the driving part, thereby causing the transmission part to separate from the driving part, resulting in the problem that the transmission part cannot transmit the driving force of the driving part to the bidirectional screw.

[0042] In one embodiment of the present invention, the stopper 19 is sleeved on the transmission part; or, the stopper 19 and the transmission part are integrally formed. The stopper 19 and the transmission part are processed separately and then sleeved on the transmission part for connection, which can reduce the processing difficulty, reduce the processing fee, and reduce the cost. The stopper 19 and the transmission part are integrally formed, which can ensure that the stopper 19 and the transmission part have a higher connection strength, thereby improving the reliability and life of the stopper 19 and the transmission part.

[0043] In one embodiment of the present invention, the stop groove includes a first stop groove 201 and a second stop groove, the first stop groove 201 is arranged in the second mounting frame 2 and extends in the radial direction of the second mounting frame 2, the first end of the first stop groove 201 is connected to the mounting channel 21, the first end of the second stop groove is connected to the second end of the first stop groove 201, the second stop groove extends in the axial direction of the second mounting frame 2 in a direction away from the driving part 4, the stop member 19 includes a first stop segment 191 and a second stop segment 192, the first stop segment 191 is connected to the second end of the first stop groove 201, and the second stop groove extends in the axial direction of the second mounting frame 2 in a direction away from the driving part 4. The stop segment 191 is in the mounting channel 21 and extends radially along the mounting channel 21. The end of the first stop segment 191 away from the transmission part extends into the first stop groove 201. The first end of the second stop segment 192 is connected to the end of the first stop segment 191 away from the transmission part. The second end of the second stop segment 192 extends into the second stop groove. A hydraulic oil chamber 203 is provided between the second stop segment 192 and the second stop groove. An oil filling hole 22 is provided on the second mounting frame 2, and the oil filling hole 22 is connected to the hydraulic oil chamber 203.

[0044] In the above technical solution, the width of the first stop groove 201 is greater than or equal to the length of the second stop segment 192 in the axial direction, thereby ensuring that the second stop segment 192 can smoothly extend into or exit the second stop groove through the first stop groove 201, and the second stop groove is used to accommodate the second stop segment 192 and limit the second stop segment 192 from moving in a direction away from the drive unit 4, thereby realizing the axial limit of the stopper. The first stop segment 191 is used to connect the second stop segment 192 and the transmission unit, and the second stop segment 192 is used to extend into the second stop groove. The axial limit of the transmission unit is realized through the cooperation between the second stop segment 192 and the second stop groove, so as to avoid the transmission unit losing connection with the drive unit 4 under the action of the bidirectional screw during the transmission process, thereby causing the transmission unit to be unable to transmit the driving force of the drive unit 4 to the bidirectional screw.

[0045] A hydraulic oil chamber 203 is provided between the second stopper section 192 and the second stopper groove, and an oil filling hole 22 is provided on the second mounting frame 2, and an oil plug is provided on the oil filling hole 22. Hydraulic oil is injected into the hydraulic oil chamber 203 through the oil filling hole 22, and the hydraulic oil chamber 203 is sealed with the oil plug after the oil filling is completed. The hydraulic oil in the hydraulic oil chamber 203 supports the second end of the second stopper section 192, and avoids the end face of the second end of the second stopper section 192 from contacting with the inner wall of the second stopper groove to generate a large friction force, resulting in the problem that the transmission member connected to the stopper cannot rotate normally. The radial width of the second stopper section 192 is consistent with the groove width of the second stopper groove along the radial direction, so as to avoid the leakage of hydraulic oil from between the second stopper section 192 and the second stopper groove. At the same time, the hydraulic oil penetrates between the second stopper section 192 and the second stopper groove, and plays a certain lubricating role, reducing the friction force of the stopper rotating in the stopper groove, thereby improving the life and stability of the stopper.

[0046] In one embodiment of the present invention, the stopper 19 is made of a self-lubricating material, such as polytetrafluoroethylene or polyimide, etc. By using a self-lubricating material to make the stopper 19, the friction between the stopper 19 and the stopper groove can be further reduced, and the amount of lubricant such as lubricating oil can be reduced, thereby improving the reliability and life of the stopper 19.

[0047] In one embodiment of the present invention, there is a certain matching gap between the first stop section 191 and the second mounting frame 2, and the width of the matching gap is 1mm to 5mm. When the stopper is installed into the stop position, the hydraulic oil in the hydraulic oil chamber 203 supports the second end of the second stopper section 192, preventing the end face of the second end of the second stopper section 192 from contacting the inner wall of the second stopper groove, and at the same time maintaining a certain gap between the first stopper section 191 and the second mounting frame 2, ensuring that the first stopper section 191 and the second mounting frame 2 will not rub against each other when the stopper rotates with the transmission member, thereby improving the life and stability of the stopper.

[0048] In one embodiment of the present invention, the length of the second stop segment 192 extending into the second stop groove is less than the distance between the oil filling hole 22 and the first end of the second stop groove, thereby avoiding the problem that the second stop segment 192 extends too deeply and blocks the oil filling hole 22, resulting in the inability to normally inject oil into the hydraulic oil chamber 203.

[0049] In one embodiment of the present invention, the clamping part also includes a moving part 5, and the transmission part includes a bidirectional screw. The moving part 5 is connected to the first end of the first clamping section 31. A screw hole is provided on the moving part 5, and the bidirectional screw is passed through the screw hole. The first end of the bidirectional screw away from the first clamping section 31 is drivingly connected to the driving part 4.

[0050] In the above technical solution, the moving part 5 cooperates with the bidirectional screw thread to convert the rotational motion of the screw into the linear motion of the moving part 5, thereby pushing or pulling the first clamping section 31. The driving part 4 usually adopts a motor or a cylinder to drive the bidirectional screw to rotate, thereby driving the clamping assembly to achieve the clamping and releasing actions.

[0051] In one embodiment of the present invention, the clamping part also includes a first connecting member 7 and a second connecting member 8, the first connecting member 7 is fixed to the first end of the first clamping section 31, one end of the second connecting member 8 is connected to the first connecting member 7, and the other end is connected to the moving part 5, and the second end of the bidirectional screw is threadedly connected to the moving part 5.

[0052] In the above technical solution, the design of the threaded connection between the bidirectional screw and the moving part 5 utilizes the characteristic that the screw can convert rotational motion into linear motion. The bidirectional screw is driven to rotate by the driving part 4, thereby pushing or pulling the moving part 5, and then driving the first clamping section 31 to move. The first connecting member 7 is used to connect the first clamping section 31 and the second connecting member 8, and the second connecting member 8 is used to connect the clamping part and the moving part 5. By providing the first connecting member 7 and the second connecting member 8, the axial linear motion of the moving part 5 along the bidirectional screw is transmitted to the first clamping section 31, thereby ensuring that the first clamping section 31 can slide along the installation channel 21, and the clamping or releasing action of the clamping part is realized.

[0053] In one embodiment of the present invention, a first transmission member 9 is provided at the first end of the bidirectional screw, the driving unit 4 includes a driving motor, the driving motor is arranged in the installation channel 21, and a second transmission member 10 is provided on the output shaft of the driving motor. The first transmission member 9 is drivingly connected to the second transmission member 10.

[0054] In the above technical solution, the driving motor is used to provide rotational power. The first transmission member 9 and the second transmission member 10 are usually transmission elements such as gears or pulleys, wherein the second transmission member 10 is directly connected to the output shaft of the driving motor and is responsible for transmitting the rotational power of the driving motor to the first transmission member 9, and the first transmission member 9 transmits the rotational power to the bidirectional screw, so that the bidirectional screw generates rotational motion.

[0055] In one embodiment of the present invention, the first transmission member 9, the second transmission member 10 and the third transmission member are all bevel gears, the rotation axes of the first transmission member 9 and the second transmission member 10 are perpendicular to each other, the rotation axes of the second transmission member 10 and the third transmission member are perpendicular, the rotation axes of the first transmission member 9 and the third transmission member are colinear, the first transmission member 9 and the second transmission member 10 are meshed with each other to achieve a driving connection, and the second transmission member 10 and the third transmission member are meshed with each other to achieve a driving connection. By using bevel gears as the first transmission member 9, the second transmission member 10 and the third transmission member, the first bidirectional screw 61 and the second bidirectional screw 62 can be rotated synchronously, the stability and accuracy of the movement of the first clamping part 34 and the second clamping part 35 are improved, and then the motor can be clamped and released synchronously and smoothly.

[0056] In one embodiment of the present invention, the clamping portion includes a first clamping portion 34 and a second clamping portion 35, and the first clamping portion 34 and the second clamping portion 35 are respectively arranged at two ends of the second mounting frame 2, and the bidirectional screw includes a first bidirectional screw 61 and a second bidirectional screw 62. The first bidirectional screw 61 can drive the first clamping portion 34 to slide along the mounting channel 21, and the second bidirectional screw 62 can drive the second clamping portion 35 to slide along the mounting channel 21. A first transmission member 9 is provided at one end of the first bidirectional screw 61 facing the driving portion 4, and the first transmission member 9 is drivingly connected to the second transmission member 10. A connecting rod 18 is provided between the first bidirectional screw 61 and the second bidirectional screw 62, and one end of the connecting rod 18 is fixedly connected to the first bidirectional screw 61, and the other end of the connecting rod 18 is fixedly connected to the second bidirectional screw 62. The thread direction of the first bidirectional screw 61 is opposite to the thread direction of the second bidirectional screw 62.

[0057] In the above technical solution, the first clamping part 34 and the second clamping part 35 cooperate with each other to clamp the motor, ensuring that the motor remains stable during the test, thereby improving the safety of the test. The first bidirectional screw 61 and the second bidirectional screw 62 are fixedly connected to form a whole through the connecting rod 18. They are driven and connected to the driving part 4 through the first transmission member 9. Only one first transmission member 9 can drive the first bidirectional screw 61 and the second bidirectional screw 62 to rotate synchronously, thereby converting the rotational power of the drive motor into linear movement, and then driving the first clamping part 34 and the second clamping part 35 to slide synchronously along the installation channel 21, thereby achieving consistency in the clamping and releasing actions. The thread direction of the first bidirectional screw 61 is opposite to the thread direction of the second bidirectional screw 62, ensuring that when the first bidirectional screw 61 and the second bidirectional screw 62 rotate in the same direction, the first clamping part 34 and the second clamping part 35 move in opposite directions, thereby achieving the clamping and releasing actions.

[0058] In an embodiment of the present invention not shown in the figures, the clamping portion includes a first clamping portion 34 and a second clamping portion 35, and the first clamping portion 34 and the second clamping portion 35 are respectively arranged at two ends of the second mounting frame 2, and the bidirectional screw includes a first bidirectional screw 61 and a second bidirectional screw 62. The first bidirectional screw 61 can drive the first clamping portion 34 to slide along the mounting channel 21, and the second bidirectional screw 62 can drive the second clamping portion 35 to slide along the mounting channel 21. A first transmission member 9 is provided at one end of the first bidirectional screw 61 close to the driving portion 4, and the first transmission member 9 is connected to the second transmission member 10. A third transmission member is provided at one end of the second bidirectional screw 62 close to the driving portion 4, and the third transmission member is drivingly connected to the second transmission member 10. The thread direction of the first bidirectional screw 61 is the same as the thread direction of the second bidirectional screw 62.

[0059] In the above technical solution, the first bidirectional screw 61 and the second bidirectional screw 62 are independent of each other, the first transmission member 9 is used to transmit the rotational force of the driving part 4 to the first bidirectional screw 61, and the third transmission member is used to transmit the rotational force of the driving part 4 to the second bidirectional screw 62. The first bidirectional screw 61 and the second bidirectional screw 62 convert the rotational power of the driving motor into the linear movement of the clamping part, thereby driving the first clamping part 34 and the second clamping part 35 to slide synchronously along the installation channel 21, so as to achieve the consistency of the clamping and releasing actions. The first transmission member 9 and the third transmission member are driven to rotate simultaneously by a driving part 4. At this time, the rotation directions of the first transmission member 9 and the third transmission member are opposite, thereby driving the first bidirectional screw 61 and the second bidirectional screw 62 to rotate in opposite directions. Therefore, the thread direction of the first bidirectional screw 61 is the same as the thread direction of the second bidirectional screw 62, ensuring that the first clamping part 34 and the second clamping part 35 move in opposite directions at the same time, thereby achieving the clamping and releasing actions.

[0060] In one embodiment of the present invention, a controller 16 is disposed on the second mounting frame 2 , and the controller 16 is communicatively connected to the driving unit 4 , and the controller 16 is communicatively connected to the test connector 12 .

[0061] In the above technical solution, the controller 16 is used to receive instructions from the operator, process and convert them into control signals that can be executed by the drive unit 4 and the test connector 12. In addition, it is also responsible for monitoring the status of the drive unit 4 and the test connector 12 to ensure the normal operation of the system. The controller 16 can send control signals to the drive unit 4 through a communication connection, such as start, stop, forward and reverse instructions, to drive the rotation of the first bidirectional screw 61 and the second bidirectional screw 62, thereby controlling the movement of the first clamping part 34 and the second clamping part 35. The controller 16 can monitor and control the test status of the connector through a communication connection with the test connector 12, such as real-time monitoring of parameters such as current, voltage, and temperature, as well as automatic control of the test process. By setting up the controller 16, the operation process is simplified, the test speed is improved, the labor intensity of the operator is reduced, and the equipment failure or test error caused by unskilled human operation or mistakes is reduced.

[0062] In one embodiment of the present invention, a first handle 15 is connected to one end of the locking portion 13 away from the test connector 12 , and a second handle 17 is provided on a side of the second mounting frame 2 away from the clamping area.

[0063] In the above technical solution, the first handle 15 enables the operator to pull the locking portion 13 to the unlocking position more conveniently and labor-savingly, so that the locking portion 13 is disengaged from the positioning hole 121 on the test connector 12, thereby unlocking the test connector 12. The second handle 17 is mainly for the operator to manually move the entire quick connector device when necessary, especially when positioning or adjusting the position, the quick connector device can be carried by grasping the second handle 17, thereby increasing the convenience of moving the equipment.

[0064] It can be seen from the above description that the above-mentioned embodiment of the present invention achieves the following technical effects: the mounting frame provides a stable mounting platform for the test connector 12 and the clamping assembly, which plays a role of support and positioning. The test connector 12 is the core component of the quick connector, which is used to directly connect to the test port of the motor to transmit the current, signal or data required for the test. The clamping part is used to clamp and fix the motor to prevent the motor from loosening or falling off during the test, thereby ensuring the safety of the test. The driving part 4 is located inside the mounting frame and is driven and connected to the clamping part through a transmission mechanism. The driving part 4 can adopt an electric, pneumatic or hydraulic drive device to provide power for the clamping and loosening action of the clamping part. The motor test quick connector provided by the present invention realizes the quick connection of the motor by setting the clamping assembly and the test connector 12, so that the operator does not need to frequently disassemble and install screws or other fixings, which greatly shortens the preparation and disassembly time of the motor test, improves the efficiency of production or R&D testing, and reduces the labor intensity of the operator.
