Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging, and in particular to a charging device for new energy vehicles and its testing method. Background Technology

[0002] With the rapid popularization of new energy vehicles, the demand for charging devices, as core supporting equipment, is increasing day by day. Existing charging devices typically include a charging main body and detachable functional modules. The functional modules are installed on the charging main body by horizontal insertion and then screw locking.

[0003] However, this traditional installation method has significant shortcomings. First, the guide slots on most charging units currently on the market for inserting the module are generally only slightly larger than the module itself. Users must align them precisely before insertion, which undoubtedly increases the actual installation difficulty. Second, after the module is inserted horizontally, screws must be tightened to secure it. During installation, the distance between the module and the charging unit is relatively short, limiting the operator's hand space, especially outdoors or in poor lighting conditions, making screw tightening inconvenient and affecting installation efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a charging device and its testing method for new energy vehicles. When using this charging device, for the installation of the module part, compared with the traditional method of horizontal insertion and screw tightening, this solution can move the installation part a little distance away, increasing the user's operating space. In addition, the placement space of the module body automatically increases after being moved out, further facilitating the user's operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A charging device for new energy vehicles includes a cabinet, a charging component installed on one side of the cabinet, a module mounting slot on one side of the cabinet, and a heat dissipation cover plate detachably installed at the slot opening of the module mounting slot.

[0007] Two mounting bracket assemblies are installed inside mounting slots. Each mounting bracket assembly includes a base plate fixedly connected to the inner wall of the mounting slot. A rotating seat is provided above the base plate. The upper front end of the base plate is rotatably connected to the rotating seat. A pneumatic telescopic structure is rotatably connected to the upper rear end of the base plate. The telescopic end of the pneumatic telescopic structure is rotatably connected to the lower rear end of the rotating seat. A fixed plate is installed inside the slot via a moving mechanism. The fixed plate can slide back and forth inside the slot. Lifting plates are provided above and below the fixed plate. The two lifting plates and the slot form a placement space. A module body is placed in each placement space. An adjustment mechanism that cooperates with the moving mechanism is installed on the rotating seat. When the moving mechanism moves forward, the adjustment mechanism can expand the placement space to facilitate the user to pick up the module body. When the moving mechanism moves backward, the adjustment mechanism can retract the placement space to achieve the positioning of the module body.

[0008] Preferably, the moving mechanism includes symmetrically formed sliding grooves on the inner walls of the left and right sides of the through groove. Each sliding groove has a threaded rod rotatably connected between its front and rear inner walls. Two drive motors are installed on the rear side of the rotating seat. The output shafts of the two drive motors extend into the sliding groove and are fixedly connected to one end of the corresponding threaded rod. Each threaded rod is threadedly connected to a slider. The opposite sides of the two sliders are fixedly connected to the two sides of the fixed plate, respectively.

[0009] Preferably, the adjustment mechanism includes a rectangular cavity disposed inside the fixed plate, a bidirectional threaded rod rotatably connected between the inner walls of the two sides of the rectangular cavity, and a sliding seat threaded to both threaded ends of the bidirectional threaded rod. A strip-shaped opening is provided at the inner top and inner bottom of the rectangular cavity, and an adjustment plate is fixedly connected to the upper and lower sides of the sliding seat. Each adjustment plate passes through the corresponding strip-shaped opening and extends into the corresponding placement space.

[0010] Preferably, multiple guide posts are fixedly connected to the upper and lower sides of the fixed plate, and the multiple guide posts penetrate the corresponding lifting plates and are slidably connected. Two folded guide grooves are opened on the inner walls of the left and right sides of the through groove. Every two folded guide grooves located on the same surface are symmetrically arranged. Connecting strips are fixedly connected to both sides of each lifting plate, and each connecting strip extends into the interior of the corresponding folded guide groove and is slidably connected.

[0011] Preferably, a transmission box is fixedly connected to the side of the slider on the left side away from the fixed plate. The left end of the bidirectional threaded rod extends into the inside of the transmission box and is fixedly connected to a worm gear. A worm is rotatably connected to the inner bottom of the transmission box. The worm meshes with the worm gear. The upper end of the worm passes through the inner top of the transmission box and is fixedly connected to a trigger gear. A rack that meshes with the trigger gear is fixedly connected between the front and rear inner walls of the slide groove on the left side.

[0012] Preferably, a rectangular groove is provided on the front side of the fixed plate, and a reducer is installed inside the rectangular groove. The input end of the reducer extends into the rectangular cavity and is equipped with a first bevel gear. A second bevel gear is fixedly connected to the middle of the bidirectional threaded rod. The first bevel gear meshes with the second bevel gear. A limit pressure bar is fixedly connected to the output end of the reducer. When the moving mechanism moves forward, the limit pressure bar rotates from a vertical position to a horizontal position as the adjusting mechanism operates. When the moving mechanism moves backward, the limit pressure bar rotates from a horizontal position to a vertical position as the adjusting mechanism operates.

[0013] Preferably, a rear limiting strip is fixedly connected to the upper rear end of the fixed plate and the upper rear end of the lifting plate located below.

[0014] Preferably, the pneumatic telescopic structure includes a lifting piston cylinder rotatably connected to the base plate, a second piston block is connected inside the lifting piston cylinder, a connecting rod is fixedly connected to one side of the second piston block, and the other end of the connecting rod is rotatably connected to the lower end of the rotating seat.

[0015] Preferably, a trigger piston cylinder is embedded in the inner wall of the through groove, a first piston block is slidably connected inside the trigger piston cylinder, the lower end of the first piston block is elastically connected to the inner bottom of the trigger piston cylinder by a spring, a stop rod is fixedly connected to the upper end of the first piston block, the inner bottom of the trigger piston cylinder is connected to the outside through a one-way air inlet, and the inner bottom of the trigger piston cylinder is connected to the inner bottom space of the lifting piston cylinder through a release pipe.

[0016] The one-way air inlet is equipped with a one-way valve that allows gas to enter the trigger piston cylinder from the outside in one direction. The release pipe is equipped with a one-way valve that allows gas to enter the bottom of the lifting piston cylinder from the trigger piston cylinder in one direction. The release pipe is equipped with a normally open solenoid valve that can be energized during the two periods of forward start-up of the drive motor.

[0017] This invention also discloses a detection method for a charging device based on new energy vehicles, used in the aforementioned charging device, comprising the following steps:

[0018] Step 1: Start the two sets of drive motors to run in the forward direction. The threaded rod drives the slider and the fixed plate to move forward as a whole, thereby expanding the placement space, tilting forward, and moving out.

[0019] Step 2: After removing the main body of the module, clean the impurities on the contact surfaces of the fixing plate, lifting plate, and rear limit strip. Visually inspect the appearance of the main body shell, wiring terminals, and plug-in pins to check for cracks, oxidation, deformation, and damage, and record the appearance defects.

[0020] Step 3: Power-on test: Remove the main module to check the continuity and operating parameters of the circuit, verify the heat dissipation duct and interface sealing of the main module, and mark the qualified modules for later use; sort and classify the unqualified modules to complete the main module performance test.

[0021] Step 4: Place the repaired module body into the expanded placement space enclosed by the lifting plate and the adjusting plate, and complete the alignment by relying on gravity to reduce the friction of contact.

[0022] Step 5: Start the two sets of drive motors to run in opposite directions. The threaded rod drives the slider and the fixed plate to move backward as a whole, triggering the gear meshing and rack linkage. The bidirectional threaded rod drives the two side adjustment plates to close, and the main body of the module is centered and positioned.

[0023] Step 6: The linkage drives the limit pressure bar to rotate and vertically seal, the lifting plate retracts along the folded guide groove to fit the fixing plate, and vertically clamps the module body to complete the upper, lower and left, right limit fixation of the module body;

[0024] Step 7: The device continues to move backward, the rear limit bar and the limit pressure bar clamp the module body, the tail of the module body connects to the internal plug connector of the cabinet, the plug-in assembly is completed, and the installation position of the module body is locked.

[0025] Step 8: Assemble the heat dissipation cover into the mounting slot of the main body of the cabinet module to complete the complete restoration and installation process of the device.

[0026] Compared with the prior art, the beneficial effects of this invention are as follows:

[0027] 1. This solution uses a drive motor to move the slider forward along the slide groove, which in turn moves the fixed plate and the lifting plate forward as a whole. This causes the rear limit bar to move forward and push the module body and the connector to automatically separate. At the same time, the linkage worm gear and the bidirectional threaded rod drive the two side adjustment plates to slide back to back, automatically expanding the left and right width of the placement space. The lifting plate is guided by the folded guide groove to slide back away from the fixed plate, simultaneously expanding the vertical spacing of the placement space. This achieves three-dimensional automatic expansion of the placement space, greatly improving the operating space and facilitating module disassembly, assembly, and maintenance.

[0028] 2. After the module is moved to the designated workstation, the compressed gas at the bottom of the piston cylinder is triggered to flow into the lifting piston cylinder through the release pipe. This pushes the rotating seat to tilt forward along the hinge point of the base plate, so that the entire placement space is switched to a forward tilting state. The module's own gravity component counteracts the forward pulling friction, and the operator can directly pull the module out from the unobstructed space at the front. When reinstalling, the rotating seat is in a backward tilting state, and the gravity component also counteracts the forward pushing friction, reducing the manual operation effort and improving the convenience of disassembly and assembly.

[0029] 3. This solution uses a bidirectional threaded rod to rotate and link the first bevel gear and reducer to drive the limiting pressure bar to switch from a horizontal to a vertical state, applying a clamping and limiting force to the front end of the module. This, combined with the rear limiting bar, achieves bidirectional limiting of the module, reinforcing the stability of the module and connector insertion. No additional screw reinforcement is required, simplifying actual operation. During the retraction process, the adjusting plates retract towards each other, and the lifting plates adhere to the fixing plate, ensuring ample space for disassembly and eliminating the need for precise manual alignment during installation.

Detailed Implementation

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0046] Reference Figures 1-14 A charging device based on new energy vehicles includes a cabinet 1, a charging component 4 installed on one side of the cabinet 1, a module mounting slot 3 opened on one side of the cabinet 1, a heat dissipation cover 2 detachably installed at the slot opening of the module mounting slot 3, the detachment method can be screw or snap connection method, a ventilation opening is opened on the rear side wall of the module mounting slot 3, and an active ventilation structure composed of multiple fans (not shown) is installed. This is the prior art. In cooperation with the heat dissipation cover 2, an active heat dissipation channel can be formed. In addition, multiple plugs are installed inside the module mounting slot 3, which can be plugged into the module body to realize the power supply of the module body.

[0047] The system also includes two mounting bracket assemblies, both of which are installed inside the mounting slot 3. Each mounting bracket assembly includes a base plate 5 fixedly connected to the inner wall of the mounting slot 3. A rotating seat 6 is provided above the base plate 5. The upper front end of the base plate 5 is rotatably connected to the rotating seat 6. A pneumatic telescopic structure is rotatably connected to the upper rear end of the base plate 5. The telescopic end of the pneumatic telescopic structure is rotatably connected to the lower rear end of the rotating seat 6. The pneumatic telescopic structure includes a lifting piston cylinder 14 rotatably connected to the base plate 5. A second piston block 27 is connected inside the lifting piston cylinder 14. A connecting rod 28 is fixedly connected to one side of the second piston block 27. The other end of the connecting rod 28 is rotatably connected to the lower end of the rotating seat 6.

[0048] The through groove 7 is equipped with a fixed plate 8 installed inside by a moving mechanism. The fixed plate 8 can slide back and forth inside the through groove 7. The moving mechanism includes sliding grooves 18 symmetrically opened on the inner walls of the left and right sides of the through groove 7. Each sliding groove 18 is rotatably connected to the inner walls of the front and rear sides. Two drive motors 13 are installed on the rear side of the rotating seat 6. The output shafts of the two drive motors 13 extend into the sliding grooves 18 and are fixedly connected to one end of the corresponding threaded rods 19. Each of the two threaded rods 19 is threadedly connected to a slider 40. The opposite sides of the two sliders 40 are fixedly connected to the two sides of the fixed plate 8 respectively. Both drive motors 13 are servo motors that can change the direction of rotation and can be controlled to run synchronously by a synchronous controller.

[0049] The fixed plate 8 is provided with lifting plates 9 on both the top and bottom. The two lifting plates 9 and the through groove 7 form a placement space. Each placement space contains a module body. Specifically, the lower control module is placed on the upper end of the lower lifting plate 9, and the upper control module is placed on the upper end of the fixed plate 8. The rotating seat 6 is equipped with an adjustment mechanism that cooperates with the moving mechanism. When the moving mechanism moves forward, the adjustment mechanism can expand the placement space to facilitate the user to pick up the module body. When the moving mechanism moves backward, the adjustment mechanism can shrink the placement space to achieve the positioning of the module body. The adjustment mechanism includes a rectangular cavity 29 set inside the fixed plate 8. A two-way threaded rod 30 is rotatably connected between the inner walls of the two sides of the rectangular cavity 29. The two threaded ends of the two-way threaded rod 30 are threadedly connected to a sliding seat 34. The inner top and inner bottom of the rectangular cavity 29 are provided with strip openings. The upper and lower sides of the sliding seat 34 are fixedly connected with adjustment plates 35. Each adjustment plate 35 passes through the corresponding strip opening and extends into the corresponding placement space.

[0050] Multiple guide posts 12 are fixedly connected to the upper and lower sides of the fixed plate 8. Each guide post 12 penetrates the corresponding lifting plate 9 and is slidably connected. Two folded guide grooves 17 are opened on the inner walls of both sides of the through groove 7. Each pair of folded guide grooves 17 located on the same surface are symmetrically arranged. Connecting strips 41 are fixedly connected to both sides of each lifting plate 9. Each connecting strip 41 extends into the corresponding folded guide groove 17 and is slidably connected. The folded guide groove 17 consists of an inclined groove and two horizontal grooves, such as... Figure 6 As shown, as the two lifting plates 9 move forward, the sliding of the connecting strip 41 within the folded guide groove 17 allows the two lifting plates 9 to move away from the fixed plate 8, thereby adjusting the vertical distance of the placement space.

[0051] Among them, the slider 40 on the left side, away from the fixed plate 8, is fixedly connected to a transmission box 36. The left end of the bidirectional threaded rod 30 extends into the transmission box 36 and is fixedly connected to a worm gear 37. A worm 38 is rotatably connected to the inner bottom of the transmission box 36. The worm 38 meshes with the worm gear 37. The upper end of the worm 38 passes through the inner top of the transmission box 36 and is fixedly connected to a trigger gear 39. A rack 20 that meshes with the trigger gear 39 is fixedly connected between the front and rear inner walls of the slide groove 18 on the left side. It should be noted that the rack 20 is like... Figure 6 As shown, only the first third of the section is toothed. At the toothed part, the rotation of the trigger gear 39 can be achieved. The worm 38 and worm wheel 37 drive the bidirectional threaded rod 30 to rotate, thereby realizing the movement of the two sliding seats 34, which in turn drives the movement of multiple adjusting plates 35. Furthermore, when the fixed plate 8 moves forward (when it has moved to the first third and continues to move forward), the two adjusting plates 35 in each placement space move in opposite directions to realize the adjustment of the distance in the left and right directions of the placement space. When it moves back, the two adjusting plates 35 in each placement space move relative to each other, which can position the corresponding module body in the center, making it convenient to connect with the plug inside the module mounting slot 3.

[0052] It should be noted that only the first third of the rack 20 has teeth. The purpose of this is to ensure that the module's position is adjusted before insertion. When removing the module, it is pulled out first, and then the space is expanded to avoid interference between the two.

[0053] The fixed plate 8 has a rectangular groove 10 on its front side, and a reducer 31 is installed inside the rectangular groove 10. The input end of the reducer 31 extends into the rectangular cavity 29 and is equipped with a first bevel gear 32. A second bevel gear 33 is fixedly connected to the middle of the bidirectional threaded rod 30. The first bevel gear 32 meshes with the second bevel gear 33. A limit pressure bar 11 is fixedly connected to the output end of the reducer 31. When the moving mechanism moves forward, the limit pressure bar 11 rotates from a vertical position to a horizontal position as the adjusting mechanism operates. When the moving mechanism moves backward, the limit pressure bar 11 rotates from a horizontal position to a vertical position as the adjusting mechanism operates. The upper rear end of the fixed plate 8 is... Both the upper rear side of the lower lifting plate 9 and the lower lifting plate 9 are fixedly connected to a rear limiting strip 16. The purpose of this structure is that after the module body is installed, the limiting pressure strip 11 is in a vertical position, which can block and limit one side of the module body and apply pressure to ensure the connection stability between the module body and the corresponding connector. When the module body is disassembled, the movement of the fixing plate 8 and the lifting plate 9 will use the rear limiting strip 16 to separate the module body from the connector. When the overall structure formed by the fixing plate 8 and the lifting plate 9 moves to its final position, the limiting pressure strip 11 is in a horizontal position, which does not block the front opening of the placement space, making it convenient for operators to take the module body.

[0054] The inner wall of the through groove 7 is fitted with a trigger piston cylinder 21. A first piston block 22 is slidably connected inside the trigger piston cylinder 21. The lower end of the first piston block 22 is elastically connected to the inner bottom of the trigger piston cylinder 21 through a spring 24. An abutment rod 23 is fixedly connected to the upper end of the first piston block 22. The inner bottom of the trigger piston cylinder 21 is connected to the outside through a one-way air inlet 25. The inner bottom of the trigger piston cylinder 21 is connected to the inner bottom space of the lifting piston cylinder 14 through a release pipe 26.

[0055] The unidirectional air inlet 25 is equipped with a one-way valve that allows gas to enter the trigger piston cylinder 21 from the outside. The release pipe 26 is equipped with a one-way valve that allows gas to enter the bottom of the lifting piston cylinder 14 from the trigger piston cylinder 21. The release pipe 26 is also equipped with a normally open solenoid valve, which can be energized during the forward start-up period of the two drive motors 13. Specifically, during normal use of the rotating seat 6, it tilts backward as a whole. During the forward movement of the fixed plate 8 and the two lifting plates 9, the two lifting plates 9 move away from the fixed plate 8. The lower lifting plate 9 presses against the abutment rod 23, thereby causing the first piston block 22 to... The piston moves downward and compresses the spring 24. However, because the normally open solenoid valve inside the release pipe 26 is energized and sealed at this time, the gas cannot be released. This causes a large amount of compressed gas to accumulate in the bottom space of the trigger piston cylinder 21. When the drive motor 13 is turned off, that is, when the fixed plate 8 and the two lifting plates 9 move forward to the position of the module body to be picked up or placed, the normally open solenoid valve is de-energized, and the gas is quickly released and enters the lifting piston cylinder 14. At this time, the fine hole 15, due to its small diameter, cannot release the gas quickly, so the gas accumulates in the bottom space of the lifting piston cylinder 14, causing the second piston block 27 to move upward. Through the connecting rod 28, it abuts the rotating seat 6 to rotate, and the whole structure forms a... Figure 14 In this state, the rotating seat 6 is tilted forward. After a period of time, the gas is released through the fine hole 15, and the rotating seat 6 will return to its original position. The advantage of this structure is that when the module is first removed, the rotating seat 6 is tilted forward. When the entire placement space is tilted forward, the friction between the module body and the inner bottom contact surface of the placement space is partially offset by the component of gravity of the module body, making it easier for the staff to remove the module body. Similarly, when the rotating seat 6 returns to its original position, the entire placement space is tilted backward. When the module body is inserted inward, the friction between the module body and the inner bottom contact surface of the placement space is partially offset by the component of gravity of the module body, making it easier to insert the module body.

[0056] In this invention, the cabinet 1 is fully assembled, and the heat dissipation cover 2 is detachably assembled to the slot of the module mounting slot 3 of the cabinet 1 by screws or buckles. The ventilation port on the rear side of the module mounting slot 3 and the built-in fan form an active ventilation structure, which, together with the heat dissipation cover 2, forms an active heat dissipation channel. The two sets of mounting bracket assemblies inside the module mounting slot 3 are in the initial assembly state. The base plate 5 is fixed to the inner wall of the module mounting slot 3. The rotating seat 6 is tilted backward relative to the base plate 5. The second piston block 27 and the connecting rod 28 inside the lifting piston cylinder 14 are kept in the initial retracted position. The fixing plate 8 is housed inside the through slot 7 of the rotating seat 6. The moving mechanism consisting of the drive motor 13, the threaded rod 19, and the slider 40 is at the rear origin position. The lifting plates 9 on the upper and lower sides of the fixing plate 8 are arranged to fit against the fixing plate 8. The connecting strip 41 is snapped into the horizontal slot on the rear side of the folded guide slot 17.

[0057] When the module body needs to be disassembled for inspection or replacement, first remove the heat dissipation cover 2, release the closed state of the module mounting slot 3, and simultaneously start the two sets of servo drive motors 13 to run in the forward direction. The synchronous controller controls the two sets of drive motors 13 to rotate synchronously in the same direction. The output shaft of the drive motor 13 drives the threaded rod 19 inside the slide 18 to rotate in the forward direction. The threaded rod 19 drives the slider 40 to slide forward along the slide 18. The slider 40 synchronously drives the fixing plate 8 and the lifting plates 9 on both sides of the fixing plate 8 to move forward along the through slot 7. The rear limit strip 16 on the fixing plate 8 and the lower lifting plate 9 moves forward, so that the module body is separated from the corresponding plug.

[0058] When the fixed plate 8 and the lifting plate 9 move forward as a whole to the area of ​​the toothed rack 20 corresponding to the slide groove 18, the trigger gear 39 at the bottom of the transmission box 36 on the left side of the slider 40 meshes with the teeth of the rack 20. The trigger gear 39 rotates passively as the device moves forward. The trigger gear 39 drives the worm 38 inside the transmission box 36 to rotate synchronously. The worm 38 meshes and drives the worm wheel 37 to rotate. The worm wheel 37 drives the coaxial fixed bidirectional threaded rod 30 to rotate inside the rectangular cavity 29. The bidirectional threaded rod 30 drives the sliding seats 34 at both ends to slide back and forth along the rod body. The sliding seats 34 drive the upper and lower adjustment plates 35 to move along the strip opening to both sides of the placement space, completing the left and right width expansion of the upper and lower two sets of placement spaces.

[0059] During the rotation of the bidirectional threaded rod 30, the second bevel gear 33 in the middle of the rod meshes and drives the first bevel gear 32 to rotate. The power is transmitted to the output end limit pressure bar 11 after the speed is adjusted by the reducer 31. The limit pressure bar 11 gradually rotates from the initial vertical state to the horizontal state, which facilitates the subsequent release of the front sealing limit of the placement space.

[0060] As the device continues to move forward, the connecting strips 41 on both sides of the lifting plate 9 slide along the horizontal groove on the rear side of the folded guide groove 17 into the inclined groove, and then slide along the inclined groove to the horizontal groove on the front side. Under the guidance of the folded guide groove 17, the upper and lower lifting plates 9 slide away from the fixed plate 8 along the guide column 12, and the vertical distance between the two placement spaces expands synchronously, completing the vertical expansion of the placement space. At the same time, the lower lifting plate 9 moves down to squeeze the upper end of the trigger piston cylinder 21 and the abutment rod 23. The abutment rod 23 pushes the first piston block 22 to slide down along the inner wall of the trigger piston cylinder 21, compressing the spring 24. The gas inside the bottom chamber of the trigger piston cylinder 21 is compressed and accumulated. During the forward start-up period of the drive motor 13, the normally open solenoid valve inside the release pipe 26 is synchronously energized and closed, and the compressed gas cannot be discharged through the release pipe 26. The gas continues to accumulate and maintain pressure.

[0061] After the fixed plate 8 and the lifting plate 9 move forward to the designated position for module pick-up and drop-off, the drive motor 13 is turned off, the moving mechanism stops moving, the normally open solenoid valve inside the synchronous release pipe 26 is de-energized and reset, and the pipeline is connected; the compressed gas accumulated at the bottom of the trigger piston cylinder 21 flows into the bottom chamber of the lifting piston cylinder 14 through the release pipe 26, and the air pressure inside the lifting piston cylinder 14 rises rapidly. The air passage rate of the fine hole 15 is limited and cannot release the pressure quickly. The air pressure pushes the second piston block 27 to move upward. The second piston block 27 drives the connecting rod 28 to move upward synchronously. The top of the connecting rod 28 pushes the rear side of the rotating seat 6 to rise. The rotating seat 6 flips and tilts forward along the front hinge point of the base plate 5, and the rotating seat 6 is switched to the forward tilting state.

[0062] After the rotating seat 6 tilts forward, the entire placement space tilts forward synchronously. The component of gravity of the module body itself counteracts the friction between the module body and the contact surfaces of the lifting plate 9 and the fixed plate 8 when the module body is pulled forward. The operator can directly pull out the module body from the unobstructed placement space at the front end to complete the module disassembly. Subsequently, the gas inside the lifting piston cylinder 14 is slowly depressurized through the fine hole 15, the second piston block 27 is reset, and the connecting rod 28 is pulled to drive the rotating seat 6 to flip backward, and the rotating seat 6 returns to the initial backward tilting state.

[0063] The operator places the repaired or new module body into the upper and lower expanded placement spaces. Since the rotating seat 6 and the placement space are in a backward tilted state, the gravity component of the module body itself counteracts the friction between the module body and the contact surfaces of the lifting plate 9 and the fixed plate 8 when the module body is pushed forward, making it convenient for the staff to put it in.

[0064] Synchronous control drives the motor 13 to rotate in reverse, causing the overall structure to retract backward along the through groove 7, triggering the gear 39 and rack 20 to mesh and repeat the above forward movement process in reverse. The worm 38 and worm wheel 37 are reset in reverse linkage, and the bidirectional threaded rod 30 rotates in reverse, driving the sliding seats 34 on both sides to move closer together. The adjusting plate 35 moves synchronously towards each other, narrowing the left and right spacing of the placement space, centering the module body to the center position of the placement space, and matching the installation position of the plug inside the module mounting slot 3.

[0065] During the reverse rotation of the bidirectional threaded rod 30, the second bevel gear 33, in conjunction with the first bevel gear 32 and the reducer 31, rotates in the opposite direction, causing the limiting pressure bar 11 to switch from a horizontal state to a vertical state. The limiting pressure bar 11 vertically blocks the front side of the placement space, completing the pre-processing of the front limiting of the module body.

[0066] As the device continues to retract, the connecting strips 41 on both sides of the lifting plate 9 slide back to the rear horizontal groove along the front horizontal groove and inclined groove of the folded guide groove 17. The two sets of lifting plates 9 move towards each other along the guide column 12 and attach to the fixing plate 8, and the vertical spacing of the placement space shrinks, completing the vertical clamping and positioning of the module body. During the retraction process, the lifting plate 9 disengages from the abutment rod 23, triggering the internal structure of the piston cylinder 21 to reset.

[0067] As the module continues to move backward, the vertical limiting pressure strip 11 applies a pressing and limiting force to the front end of the module body, which, together with the rear limiting strip 16, achieves bidirectional limiting of the module body, strengthens the stability of the module body and the connector, and completes the overall replacement process.

[0068] This invention also discloses a detection method for a charging device based on new energy vehicles, used in the aforementioned charging device, comprising the following steps:

[0069] Step 1: Start the two sets of drive motors 13 to run in the forward direction. The threaded rod 19 drives the slider 40 and the fixed plate 8 to move forward as a whole, thereby expanding the placement space, tilting forward, and moving out.

[0070] Step 2: After removing the main body of the module, clean the impurities on the contact surfaces of the fixing plate 8, lifting plate 9, and rear limit strip 16. Visually inspect the appearance of the main body shell, wiring terminals, and plug-in pins of the module, check for cracks, oxidation, deformation and damage, and record the appearance defects.

[0071] Step 3: Power-on test: Remove the main module to check the continuity and operating parameters of the circuit, verify the heat dissipation duct and interface sealing of the main module, and mark the qualified modules for later use; sort and classify the unqualified modules to complete the main module performance test.

[0072] Step 4: Place the repaired module body into the expanded placement space formed by the lifting plate 9 and the adjusting plate 35, and complete the alignment by relying on gravity to reduce the friction of contact.

[0073] Step 5: Start the two sets of drive motors 13 to run in opposite directions. The threaded rod 19 drives the slider 40 and the fixed plate 8 to move backward as a whole. The trigger gear 39 meshes with the rack 20 in linkage. The bidirectional threaded rod 30 drives the two side adjustment plates 35 to close together, and the main body of the module is centered and positioned.

[0074] Step 6: The linkage drives the limit pressure strip 11 to rotate and vertically seal, the lifting plate 9 retracts along the folded guide groove 17 to fit the fixing plate 8, vertically clamping the module body, completing the upper, lower and left, and right limit fixing of the module body;

[0075] Step 7: The device continues to move backward, and the rear limit bar 16 and the limit pressure bar 11 clamp the module body. The tail of the module body connects to the internal connector of the cabinet 1 to complete the plug-in assembly and lock the module body installation position.

[0076] Step 8: Assemble the heat dissipation cover 2 into the mounting slot 3 of the main body of the cabinet 1 module, and complete the complete restoration and installation process of the device.

[0077] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
