A second fitting portion parallel to the first fitting portion is provided inside the adjusting seat, and the second fitting portion is connected to the end of the ramp.

[0017] A further technical improvement of the present invention lies in that: a piston block is installed on the surface of the lifting plate extending into the sleeve frame, and a compression spring is sleeved outside the lifting plate and above the piston block.

[0021] A further technical improvement of the present invention lies in that: the correction member includes a fixed side plate provided on the front side of the lifting vertical plate. A clamping block that is limited and slidable on the support is provided on one side of the fixed side plate. A telescopic member is provided between the clamping block and the fixed side plate, and an elastic member II is sleeved outside the telescopic member.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. First, the battery unit is calibrated by the leveling unit, and the clamping and placement positions are the same each time to ensure the accuracy of the test. Before clamping the battery unit, the cylinder two pushes the telescopic part to slide longitudinally. Then, the position of the battery unit is limited by the positioning unit. At this time, the conductive copper bar is located between the external circuit and the power transmission copper bar. Through the reset of the telescopic part in the longitudinal direction, the conductive copper bar enters the slot, and its position is limited. In the charging state, the transverse guide rail drives the push block to move towards the power transmission copper bar and contacts it. At this time, the power module supplies current to the battery unit. The current flows from the power transmission copper bar of the power module to the conductive copper bar of the battery unit and then enters the battery for charging. During discharge, the transverse guide rail drives the conductive copper bar clamped in the telescopic part to move in the reverse direction, and the conductive copper bar is directly connected to the external circuit located above the push block and inside the test chamber, realizing the automatic charge and discharge test of the battery unit, improving the test efficiency. According to different test instructions, the opening and closing unit makes different actions, and the copper bar connection method is adopted. Compared with the method of using cables, the line loss is smaller.

[0024] 2. By setting the positioning unit, the battery unit is clamped to the fixed position of the support. The lifting plate rises to drive the clamping seat to leave the opening and rise. During this process, the two lifting plates approach or move away from each other. When approaching each other, the battery unit with a shorter installation length is installed. When moving away from each other, the battery unit with a longer installation length is installed, improving the applicability of the test. When the inner end face of the clamping pad contacts one end of the battery unit, the driving unit one drives the mounting seat and the adjusting seat to slide horizontally. At this time, the inner side face of the clamping pad positions the battery unit to ensure stable testing of the battery unit and avoid contact failure or loosening.

[0025] 3. Before the battery unit is positioned, the lifting vertical plate rises, places the battery unit between the two calibration parts, and makes the battery flush with the inner wall surface of the lifting vertical plate. When entering the calibration part, the battery unit enters through the clamping block, leveling the battery units of different length specifications and improving the test range.

[0026] 4. A power module is equipped at the top of the test rack in each test chamber, dispersing the volume of the previous box-type power supply, reducing the space occupied by the power module in the test chamber, and making the temperature of the cavity more uniform.

Detailed implementation manners

[0036] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0037] Please refer to Figures 1-7As shown in the figure, the present invention provides an energy-saving water-cooled all-in-one machine, which includes a machine body 1. Four test compartments 2 are provided inside the machine body 1. A support 3 for testing battery units is installed on the bottom surface of the inner cavity of each test compartment 2. A leveling unit for calibrating the battery unit is provided at the edge of the upper surface of the support 3. And a positioning unit for positioning the battery unit is provided on one side of the upper surface of the support 3 where the leveling unit is located. A test rack 4 is provided above the support 3. A power module 5 is installed on the top surface of the test rack 4. And a jaw unit for transferring the calibrated and leveled battery unit is installed on the lower surface of the test rack 4. An opening and closing unit for power-on detection of the battery unit is provided on one side of the upper surface of the support 3 close to the positioning unit. The end of the battery unit is soft-connected with a conductive copper bar 30. During the charge and discharge detection of the battery unit, first place the battery at the position of the leveling unit. After being calibrated by fitting with the leveling unit, it is clamped by the jaw unit to the position of the positioning unit, that is, the clamping and placement positions are the same each time, ensuring the accuracy of the test. It is convenient to power on or off the conductive copper bar 30 to enable the charge and discharge detection of the battery unit;

[0038] The opening and closing unit includes a transverse guide rail 6. At the upper end of the transverse guide rail 6, there is a push block 23 moving horizontally. And on the support plate at the end of the upper surface of the transverse guide rail 6, a second cylinder 24 is installed. Initially, the push block 23 is located at the middle position of the transverse guide rail 6. The driving end of the second cylinder 24 is connected with a telescopic part moving vertically. The telescopic part is in contact with the push block 23. And on the side surface of the telescopic part, there is a slot 29 for limiting the conductive copper bar 30. One end of the slot 29 is open and its end is closed. The bottom of the power supply module 5 extends through the upper part of the test rack 4 and is provided with a power transmission copper bar 28 for reinforcement support. The power transmission copper bar 28 is electrically connected with the conductive copper bar 30. On the surface of the push block 23, there is a notch. On the surface of the telescopic part, there is a vacancy part communicating with the slot 29. When controlling the contact between the conductive copper bar 30 and the power transmission copper bar 28, the second cylinder 24 is used to push the telescopic part to slide vertically. The battery unit is positioned by the positioning unit to ensure its stability. At this time, the conductive copper bar 30 is located on one side of the push block 23, that is, the conductive copper bar 30 is located between the external circuit and the power transmission copper bar 28. Through the vertical reset of the telescopic part, at this time, the conductive copper bar 30 enters into the slot 29 to limit the position of the conductive copper bar 30. When the battery unit is in the charging state, the transverse guide rail 6 drives the push block 23 to move towards the power transmission copper bar 28 and contact it. At this time, the power supply module 5 supplies current to the battery unit. The current flows from the power transmission copper bar 28 of the power supply module 5 to the conductive copper bar 30 of the battery unit and then enters the battery for charging; during discharging, the transverse guide rail 6 drives the conductive copper bar 30 clamped in the telescopic part to move in the reverse direction. The conductive copper bar 30 is directly connected with the external circuit located above the push block 23 and inside the test machine chamber 2. At this time, the electric energy released by the battery unit flows to the load through the conductive copper bar 30, thereby realizing the automatic charge and discharge test of the battery unit, improving the test efficiency, making different actions according to different test instructions, and adopting the connection method of copper bars. Compared with the method of using cables, the line loss is smaller.

[0039] Among them, at the top of the test rack 4 in each test machine chamber 2, a power supply module 5 is equipped, dispersing the volume of the previous box-type power supply, making the space occupied by the power supply module 5 in the test machine chamber 2 smaller, making the temperature of the cavity more uniform, and the heat dissipation of the water-cooled all-in-one machine adopts the water-cooling scheme, which is a mature technical means in the field.

[0040] Refer to Figure 4As shown, the telescopic part includes a limit member 25 and a plug-in member 26. A limit cavity is provided on the side of the plug-in member 26 away from the slot 29. The end of the limit member 25 is movably installed in the limit cavity, and an elastic member 27 is sleeved outside the limit member 25 inserted into the outside of the limit cavity. The plug-in member 26 is in sliding fit with the push block 23. When the telescopic part is pushed to move, at this time, the slot 29 in the plug-in member 26 has been inserted into the conductive copper bar 30. When charging the battery unit, the telescopic part is pushed to move to the position of the power transmission copper bar 28. In this state, the end of the limit member 25 slides in the limit cavity at the top of the plug-in member 26 and compresses the elastic member 27; when charging, the limit member 25 moves closer to the inner end of the limit cavity, stretching the elastic member 27 until the conductive copper bar 30 is connected to the external circuit.

[0041] Refer to Figure 2 As shown, the clamping unit includes a vacant slot 7 provided on the bottom surface of the support 3. A driving unit 8 is provided inside the vacant slot 7. An installation seat 9 slides outside the driving unit 8. An adjustment seat 10 is installed on the top surface of the installation seat 9. A lifting plate 11 that slides in two directions is slidably provided inside the adjustment seat 10. A clamping seat 15 is fixed on the upper end surface of the lifting plate 11. A clamping pad 16 that contacts the battery unit is installed on the side surface of the clamping seat 15. The clamping pad 16 is set in an L shape. An opening 14 for the clamping seat 15 to pass through is provided on the upper surface of the support 3. When the battery unit is clamped to the fixed position of the support 3, the clamping seat 15 is driven by the lifting of the lifting plate 11 to leave the opening 14 and rise. During this process, the two lifting plates 11 approach or move away from each other. When approaching each other, the battery unit with a shorter installation length is installed. When moving away from each other, the battery unit with a longer installation length is installed, improving the applicability of the test. When the inner end surface of the clamping pad 16 contacts one end of the battery unit, the driving unit 8 drives the installation seat 9 and the adjustment seat 10 to slide horizontally. At this time, the inner side surface of the clamping pad 16 positions the battery unit to ensure the stable installation of the battery unit.

[0042] Refer to Figure 2 and Figure 3As shown in the figure, a multi-stage telescopic rod 19 is installed on the side of the take-off and landing plate 11. A guiding vertical groove 18 is provided on the inner wall surface of the vacant groove 7. One side at the top of the guiding vertical groove 18 communicates with a guiding horizontal groove 12. A limiting block 13 that slides inside the guiding vertical groove 18 and the guiding horizontal groove 12 is fixed at the end of the multi-stage telescopic rod 19. When an upward thrust is applied to the take-off and landing plate 11, it rises upward. At this time, the limiting block 13 slides in the guiding vertical groove 18, and the multi-stage telescopic rod 19 realizes different states according to the movement path of the take-off and landing plate 11, that is, when the take-off and landing plate 11 slides towards the middle, the multi-stage telescopic rod 19 is in the extended and opened state; when the take-off and landing plate 11 slides near the end, the multi-stage telescopic rod 19 is in the retracted state. When the limiting block 13 reaches the position of the guiding horizontal groove 12, through the drive of the first driving unit 8, the adjusting seat 10 and the take-off and landing plate 11 slide together. At this time, the limiting block 13 slides into the guiding horizontal groove 12, providing a guiding effect for the movement of the take-off and landing plate 11.

[0043] Refer to Figure 3 As shown in the figure, a driving screw rod 17 driven by a built-in double-axis motor is provided inside the adjusting seat 10. And a first fitting part 22 is provided in the inner cavity of the adjusting seat 10. Ramps 21 are provided on both sides of the first fitting part 22. A sleeve frame 20 is threadedly connected to the outside of the driving screw rod 17. The bottom of the take-off and landing plate 11 is movably installed inside the sleeve frame 20. The bottom surface of the sleeve frame 20 contacts the first fitting part 22, and both sides of the bottom surface of the sleeve frame 20 are in contact with the corresponding ramps 21. A second fitting part parallel to the first fitting part 22 is provided inside the adjusting seat 10. The second fitting part is connected to the end of the ramp 21; a piston block is installed on the surface of the take-off and landing plate 11 extending into the sleeve frame 20. And a compression spring is sleeved on the outside of the take-off and landing plate 11 above the piston block, and a tension spring is sleeved on the outside of the take-off and landing plate 11 below the piston block. When the sleeve frame 20 slides close to the middle, at this time, due to the pushing action of one side of the bottom surface of the take-off and landing plate 11 against one ramp 21, the position of the take-off and landing plate 11 rises, that is, the piston block slides inside the sleeve frame 20, the top compression spring is in a compressed state, and the bottom tension spring is in a stretched state. In this state, the multi-stage telescopic rod 19 is in the extended state; when the sleeve frame 20 slides close to the end, due to the pushing action of the other side of the bottom surface of the take-off and landing plate 11 against the corresponding ramp 21, the bottom surface of the take-off and landing plate 11 enters the corresponding second fitting part, completing the pushing action, and finely adjusting the distance between the two take-off and landing plates 11 in the two second fitting parts, thereby changing the distance of the clamping pads 16 to adapt to the positioning of the battery unit.

[0044] Refer to Figure 5 As shown in the figure, the jaw unit includes a second driving unit 31. An electric push rod 32 is installed on the slider outside the second driving unit 31. The driving end of the electric push rod 32 is connected to a rotary driving unit 33. A jaw 34 for clamping the battery unit is fixed at the driving end of the rotary driving unit 33;

[0045] A limit rod is installed on the bottom surface of the slider, which slides with the mounting plate on the rotation drive unit 33. The battery cell corrected by the leveling unit is clamped by the clamp 34, and then the direction of the battery cell is changed by the sliding transfer of the drive unit 2 31, in cooperation with the rotation drive unit 33, so as to change the position of the battery cell.

[0046] See also Figure 6 As shown, the leveling unit includes a lifting plate 35 arranged at the edge of the bracket 3, and the lifting plate 35 is driven by a lifting drive unit built into the bracket 3. Correction pieces are provided at both ends of the front side of the lifting plate 35; the correction piece includes a fixed side plate 36 arranged at the front side of the lifting plate 35, and one side of the fixed side plate 36 is provided with a clamping block 37 that slides on the upper limit of the bracket 3, and a telescopic piece is provided between the clamping block 37 and the fixed side plate 36, and an elastic piece 38 is provided on the outer sleeve of the telescopic piece. Before the battery unit is positioned, the lifting plate 35 is in an open state, and the battery unit is placed between the two correction pieces, and the battery is flush with the inner wall surface of the lifting plate 35. When entering the correction piece, the battery unit enters through the clamping block 37. Due to the elastic limiting connection between the clamping block 37 and the fixed side plate 36, battery units of different lengths can be leveled, thereby increasing the test range, and the position of the clamping unit for clamping and placing is consistent each time, and there is no need to manually adjust the placement position of the battery unit, thereby ensuring the accuracy of the test.

[0047] When the present invention is used, the battery unit is first calibrated by the leveling unit, and the position of each clamping and placement is consistent to ensure the accuracy of the test. Before the battery unit is fixed, the telescopic part is pushed by the cylinder 24 to slide longitudinally, and then the battery unit is limited in position by the clamping unit. At this time, the conductive copper bar 30 is located between the external circuit and the power transmission copper bar 28. The conductive copper bar 30 enters the slot 29 through the resetting of the telescopic part in the longitudinal direction, and the position of the conductive copper bar 30 is limited. In the charging state, the push block 23 is driven by the transverse guide rail 6 to move in the direction of the power transmission copper bar 28 and is aligned with the power transmission copper bar 28. When the battery is in contact, the power module 5 provides current to the battery cell, and the current flows to the conductive copper bus 30 of the battery cell through the power transmission copper bus 28 of the power module 5, and then enters the battery for charging; when discharging, the transverse guide rail 6 drives the conductive copper bus 30 engaged in the telescopic part to move in the opposite direction, and the conductive copper bus 30 is directly connected to the external circuit on the upper part of the push block 23 and located in the test machine compartment 2, so as to realize the automatic charge and discharge test of the battery cell, improve the test efficiency, and make different actions according to different test instructions. The copper bus connection method has smaller line loss than the cable method;

[0048] By setting the clamping position unit, the battery unit is clamped to the fixed position of the support 3. With the elevation of the lifting plate 11, the clamping seat 15 moves away from the opening 14 and rises. During this process, the two lifting plates 11 approach or move away from each other. When they approach each other, the battery unit with a shorter installation length is installed; when they move away from each other, the battery unit with a longer installation length is installed, improving the applicability of the test. When the inner end face of the clamping pad 16 contacts one end of the battery unit, the driving unit one 8 drives the mounting seat 9 and the adjusting seat 10 to slide horizontally. At this time, the inner side face of the clamping pad 16 positions the battery unit to ensure stable installation of the battery unit.

[0049] Before the battery unit is clamped in position, the lifting vertical plate 35 rises. The battery unit is placed between the two correction members and is flush with the inner wall surface of the lifting vertical plate 35. When entering the correction members, the battery unit enters through the clamping block 37 to level the battery units of different length specifications, improving the test range.

[0050] At the top of the test rack 4 in each test chamber 2, a power module 5 is equipped. The volume of the previous box-type power supply is dispersed, making the space occupied by the power module 5 in the test chamber 2 smaller and making the temperature in the cavity more uniform.

[0051] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
