Description

Technical Field

[0001] The present invention relates to the field of charging pile detection, and particularly to a detection device for a new energy vehicle charging pile. Background Art

[0002] The detection of new energy vehicle charging piles requires the use of a variety of different devices because charging piles involve multiple key performance indicators and safety requirements, and different devices are for different detection needs. For example, a power quality analyzer is used to test power parameters such as voltage, current, and harmonics to ensure that the charging process complies with national standards.

[0003] Currently, the detection of new energy vehicle charging piles requires carrying a variety of devices and then connecting various different devices to the charging pile one by one for separate testing. There are problems such as low detection efficiency and cumbersome operation. Since different devices need to be connected separately, each switch requires reconnection and adjustment, resulting in a slower overall detection speed. At the same time, manual connection is prone to errors, affecting the accuracy of the test and making it difficult to meet the detection needs of large-scale and high-efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings that the current detection of charging piles requires carrying a variety of devices, connecting them to the charging pile one by one for testing, with frequent device switching, cumbersome connection and adjustment, slow detection speed, prone to errors in manual connection, and difficult to meet the high-efficiency large-scale detection needs, therefore, a detection device for a new energy vehicle charging pile is needed. By pre-batching the wiring harnesses of a variety of devices on this device, it is only necessary to connect to the charging pile once during detection, and then different devices can be intermittently switched for testing, avoiding the cumbersome operation and errors caused by frequent plugging and unplugging; improving the overall detection efficiency, optimizing the detection process, making the test more efficient and standardized, and suitable for the detection needs of large-scale and high-frequency charging piles.

[0006] Further, the fixing mechanism includes sliding plates, several sliding plates are slidably arranged on the hexagonal cylinder, and two return springs are connected between each sliding plate and the hexagonal cylinder.

[0007] Furthermore, the connecting mechanism includes a fixed bar. Two fixed bars are installed on the housing and the circular cover. One end of each of the two fixed bars is provided with a slot. The ends of the two fixed bars with slots are located inside the circular cover. Elastic conductive sheets are provided in the slots of the two fixed bars. Two wires are installed at the other ends of the two fixed bars. The two wires are electrically connected to the two elastic conductive sheets. Clips are installed at the other ends of the two wires.

[0008] Furthermore, the driving mechanism includes a slide rail. A slide rail is installed on one side inside the housing. An electric slider is slidably provided on the slide rail. A main rack is installed on the electric slider. An overrunning clutch is installed at the lower part of the rotating cylinder. A main gear is provided on the overrunning clutch.

[0009] Furthermore, the conducting mechanism includes sliding bars. A number of sliding bars are slidably provided on the rotating cylinder. A conductive bar is embedded in each sliding bar. Every two adjacent sliding bars form a group. A T-shaped frame is fixedly installed at the lower part of each group of sliding bars. A lifting ring is slidably provided inside the housing. Two vertical springs are connected between the lifting ring and the housing. Two contact bars are installed at the bottom of the lifting ring. A sliding frame is slidably provided inside the housing. A top piece is installed on the other side of the sliding frame. The top piece is composed of an inclined plane and a horizontal plane. Two bottom springs are connected between the sliding frame and the housing.

[0010] Furthermore, a correcting mechanism is also provided on the rotating cylinder and the sliding frame. The correcting mechanism is used to correct the position of the conductive bar. The correcting mechanism includes a hexagonal block. A hexagonal block is fixedly installed on the rotating cylinder. A correcting frame is installed on the sliding frame. Guide rollers are rotatably provided at both ends of the correcting frame.

[0011] Furthermore, a clamping mechanism is also provided on the rotating cylinder, the fixed bar and the sliding frame. The clamping mechanism is used to push the two elastic conductive sheets to deform and swing. The clamping mechanism includes a trapezoidal block. A trapezoidal block is installed on the horizontal plane of the top piece. A guide ring is fixedly installed inside the rotating cylinder. A hexagonal ejector rod is slidably provided on the guide ring. The lower end of the hexagonal ejector rod slidably passes through the lifting ring. A secondary rack is slidably provided between the two fixed bars. A number of tooth blocks are provided on the secondary rack. Two tooth springs are connected between the upper part of the secondary rack and the two fixed bars. Threaded rods are connected to the mutually adjacent sides of the two fixed bars. A secondary gear is installed at one end of each of the two threaded rods close to each other. The two secondary gears are both meshed with the number of tooth blocks on the secondary rack. The other ends of the two threaded rods are respectively located on the mutually adjacent sides of the two elastic conductive sheets.

[0012] Furthermore, gaskets are also included. Gaskets are rotatably installed at the other ends of the two threaded rods.

[0013] Furthermore, the gasket is made of insulating material, and the two gaskets are respectively in contact with the sides of the two elastic conductive sheets that are close to each other.

[0014] Advantages of the present invention: 1. The inclined surface on the top sheet drives the two contact rods to drive the lifting ring, six T-shaped frames, twelve sliding strips, and twelve conductive strips to move upward; after two of the conductive strips are inserted into the two slots on the two fixed strips and contact the two elastic conductive sheets, the electrical signal of the charging pile output port is sequentially transmitted to one of the detection devices through the clip, wire, elastic conductive sheet, and conductive strip. The device reads and records the measurement data, so as to achieve rapid switching of six different devices, thereby improving the detection efficiency of the charging pile, ensuring that different devices can quickly and accurately detect the charging pile, reducing manual operation, improving the degree of automation, reducing human error, making the detection process more stable and reliable, and being applicable to the detection requirements of large-scale and high-frequency charging piles.

[0015] 2. The sliding frame drives the correction frame and the two guide rollers to move towards the hexagonal block. Since the opening width of the correction frame is exactly the distance between two opposite faces of the hexagonal block, the hexagonal block can be slightly corrected under the action of the correction frame; the two guide rollers will rotate after contacting the hexagonal block, reducing the wear of the correction frame on the hexagonal block, prolonging the service life of the correction frame and the hexagonal block, and improving the durability and stability of the device; the correction frame can precisely correct the hexagonal block, rotating cylinder, sliding strip, and conductive strip, so that two of the conductive strips are more accurately located directly below the two elastic conductive sheets, ensuring stable contact between the conductive strip and the elastic conductive sheet, improving the reliability of electrical signal transmission, and improving the overall detection efficiency to make the detection process smoother and more efficient.

[0016] 3. Under the action of the trapezoidal block, the hexagonal ejector rod moves upward. The guiding ring guides the hexagonal ejector rod. The upper end of the hexagonal ejector rod drives the secondary rack to move upward, and the two tooth springs are stretched accordingly. Under the action of the tooth blocks on the secondary rack, the two secondary gears rotate. The rotation of the two secondary gears drives the two threaded rods to rotate. While rotating, the two threaded rods move away from each other. The two threaded rods drive the two secondary gears to rotate and move away from each other at the same time. The two secondary gears rotate and move away from each other on the tooth blocks of the secondary rack. The two threaded rods drive the two gaskets to move away from each other. The two gaskets drive the two elastic conductive sheets to deform and swing, pressing against the conductive bars inserted into the two slots of the two fixing bars, making the contact between the elastic conductive sheets and the conductive bars closer, improving the stability and reliability of electrical signal transmission, reducing signal fluctuations caused by poor contact, and improving the accuracy of charging pile detection. The two gaskets are in contact with the two elastic conductive sheets, preventing the two threaded rods from driving the two gaskets to rotate, reducing the wear of the two elastic conductive sheets, extending the service life of the elastic conductive sheets, and improving the durability and stability of the overall device. The two gaskets are made of insulating materials, which can effectively prevent signal interference, improve the safety and reliability of charging pile detection, make the charging pile detection process more accurate, efficient and stable, and meet the requirements of high-efficiency large-scale detection.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: A detection device for a new energy vehicle charging pile, as Figures 1-10 shown, includes a housing 1, a round cover 4 is installed on the upper part of the housing 1, a rotating cylinder 2 is rotatably provided between the housing 1 and the round cover 4 through a bearing, a hexagonal cylinder 3 is installed in the middle of the rotating cylinder 2, six placement grooves 31 for placing detection devices are opened on the hexagonal cylinder 3, a fixing mechanism for fixing the detection devices is provided on the hexagonal cylinder 3, a connection mechanism for connecting the charging pile and the detection devices is provided on the housing 1 and the round cover 4, a driving mechanism for intermittently driving each detection device to switch is provided on the housing 1 and the rotating cylinder 2, and a conduction mechanism for conducting the detection devices and the charging pile is provided on the housing 1 and the rotating cylinder 2.

[0033] The fixing mechanism includes a sliding plate 51. Six sliding plates 51 are slidably arranged on the hexagonal cylinder 3. Two return springs 52 are connected between each of the six sliding plates 51 and the hexagonal cylinder 3. The sliding plate 51 covers a part of the placement groove 31.

[0034] The connecting mechanism includes a fixing bar 61. Two fixing bars 61 are installed on the housing 1 and the round cover 4. One end of each of the two fixing bars 61 is provided with a slot. The ends of the two fixing bars 61 with slots are located inside the round cover 4. Elastic conductive sheets 62 are arranged in the slots of the two fixing bars 61. Two wires 63 are installed at the other ends of the two fixing bars 61. The two wires 63 are electrically connected to the two elastic conductive sheets 62. Clips 64 for connecting to the output port of the charging pile are installed at the other ends of the two wires 63.

[0035] The driving mechanism includes a slide rail 71. A slide rail 71 is installed on one side inside the housing 1. An electric slider 72 is slidably arranged on the slide rail 71. A main rack 73 is installed on the electric slider 72. An overrunning clutch 74 is installed at the lower part of the rotating cylinder 2. A main gear 75 is arranged on the overrunning clutch 74. After the main rack 73 moves, it will mesh with the main gear 75.

[0036] The conduction mechanism includes sliding bars 81. A number of sliding bars 81 are slidably arranged on the rotating cylinder 2. A conductive bar 82 is embedded in each of the sliding bars 81. Two of the conductive bars 82 are located directly below the two elastic conductive sheets 62. Every two adjacent sliding bars 81 form a group. A T-shaped frame 83 is fixedly installed at the lower part of each group of sliding bars 81. A lifting ring 84 is slidably arranged inside the housing 1. Two vertical springs 841 are connected between the lifting ring 84 and the housing 1. The lifting ring 84 can slide up and down along the housing 1. Two contact rods 85 are installed at the bottom of the lifting ring 84. A sliding frame 86 is slidably arranged inside the housing 1. The sliding frame 86 can slide horizontally along the housing 1. One side of the sliding frame 86 is at the same horizontal plane as the main rack 73. After the main rack 73 moves, it will contact one side of the sliding frame 86. A top piece 87 is installed on the other side of the sliding frame 86. The top piece 87 is composed of an inclined surface and a horizontal surface. Two bottom springs 88 are connected between the sliding frame 86 and one side inside the housing 1.

[0037] The operator first connects the interface end of one of the detection devices to the lower parts of two of the conductive bars 82, then pushes one of the sliding plates 51 upward. Two of the return springs 52 are stretched accordingly, causing one of the placement slots 31 to be completely exposed. Then, the detection device is placed into the placement slot 31. Next, the sliding plate 51 is released. Under the action of the two return springs 52, the sliding plate 51 will move downward to reset. By repeating this process, six different detection devices can be placed into the six placement slots 31. The six placement slots 31 and the six sliding plates 51 can limit and fix different detection devices. Then, the operator connects the clip 64 to the output port on the charging pile. Then, the operator controls the electric slider 72 to drive the main rack 73 to move along the slide rail 71. After the main rack 73 meshes with the main gear 75, they will separate. During the meshing process of the main rack 73, the main gear 75 is driven to rotate 60 degrees and then stops. The main gear 75 drives the rotating cylinder 2, the hexagonal cylinder 3, twelve sliding bars 81, twelve conductive bars 82, six T-shaped frames 83, and the six detection devices placed in the six placement slots 31 to rotate 60 degrees and then stop. The six T-shaped frames 83 will rotate along the lifting ring 84. When the main rack 73 separates from the main gear 75, the main rack 73 just contacts one side of the sliding frame 86. The main rack 73 continues to drive the sliding frame 86 and the top piece 87 to move, and the two bottom springs 88 are stretched accordingly. When the inclined surface on the top piece 87 contacts the two contact rods 85, under the action of the inclined surface on the top piece 87, the two contact rods 85 drive the lifting ring 84, six T-shaped frames 83, twelve sliding bars 81, and twelve conductive bars 82 to move upward. Two of the conductive bars 82 are inserted into two slots on the two fixing bars 61 and contact two elastic conductive sheets 62. After the horizontal surface on the top piece 87 moves below the two contact rods 85, the two contact rods 85, the lifting ring 84, six T-shaped frames 83, twelve sliding bars 81, and twelve conductive bars 82 no longer move upward. The electrical signal from the output port of the charging pile can then be transmitted to one of the detection devices in sequence through the clip 64, the wire 63, the elastic conductive sheet 62, and the conductive bar 82. The device reads the data measured on the detection device and records it;After detecting and recording a set of data, the operator controls the electric slider 72 to drive the main rack 73 to move backward along the slide rail 71 for reset. As the main rack 73 moves backward, under the action of the two bottom springs 88, the sliding frame 86 and the top piece 87 will move backward for reset. The horizontal plane and the inclined plane on the top piece 87 will sequentially separate from the two contact rods 85. Under the action of the two vertical springs 841, the lifting ring 84, the six T-shaped frames 83, the twelve sliding bars 81, and the twelve conductive bars 82 will move downward for reset. Two of the conductive bars 82 will be pulled out from the two slots on the two fixed bars 61 and separated from the two elastic conductive sheets 62. Then, after the main rack 73 meshes with the main gear 75, they will separate. During the meshing process of the main rack 73, it drives the main gear 75 to rotate backward by sixty degrees and then stops. Under the action of the overrunning clutch 74, the main gear 75 will not drive the rotating cylinder 2, the hexagonal cylinder 3, the twelve sliding bars 81, the twelve conductive bars 82, the six T-shaped frames 83, and the six detection devices placed in the six placement slots 31 to rotate. Repeating this process can quickly switch six different devices to detect the charging pile, improving the detection efficiency. After the charging pile is detected, the operator removes the clip 64 from the output port of the charging pile and then clips the clip 64 on the output port of another charging pile to be detected, enabling rapid and accurate detection of different charging piles continuously.

[0038] Embodiment 2: On the basis of Embodiment 1, as Figures 6-9 shown, it further includes a correction mechanism provided on the rotating cylinder 2 and the sliding frame 86. The correction mechanism is used to correct the position of the conductive bar 82, enabling two of the conductive bars 82 to be more precisely located directly below the two elastic conductive sheets 62. The correction mechanism includes a hexagonal block 91. A hexagonal block 91 is fixedly installed on the rotating cylinder 2, and a correction frame 92 is installed on the sliding frame 86. Both ends of the correction frame 92 are rotatably provided with a guide roller 93 through bearings. The opening width of the correction frame 92 is exactly the distance between two opposite faces of the hexagonal block 91.

[0039] When the rotating cylinder 2 drives the hexagonal block 91 to rotate, the hexagonal block 91 will not contact the correction frame 92. When the rotating cylinder 2 rotates sixty degrees and stops, the sliding frame 86 drives the correction frame 92 and the two guide rollers 93 to move towards the hexagonal block 91. Since the opening width of the correction frame 92 is exactly the distance between two opposite faces of the hexagonal block 91, under the action of the correction frame 92, the hexagonal block 91 can be slightly corrected. After the two guide rollers 93 contact the hexagonal block 91, the two guide rollers 93 will rotate, thereby reducing the wear of the correction frame 92 on the hexagonal block 91. The correction frame 92 can correct the hexagonal block 91, the rotating cylinder 2, the sliding bar 81, and the conductive bar 82, enabling two of the conductive bars 82 to be more precisely located directly below the two elastic conductive sheets 62 and improving the detection efficiency of the charging pile.

[0040] Embodiment 3: On the basis of Embodiment 2, as Figures 9-13 shown, it further includes a clamping mechanism arranged on the rotary drum 2, the fixed strip 61 and the sliding frame 86. The clamping mechanism is used to push the two elastic conductive sheets 62 to deform and swing, so that the elastic conductive sheets 62 can be in closer contact with the conductive strip 82. The clamping mechanism includes a trapezoidal block 101. A trapezoidal block 101 is installed on the horizontal plane of the top sheet 87. A guide ring 102 is fixedly installed in the rotary drum 2. A hexagonal ejector rod 103 is slidably arranged on the guide ring 102. The lower end of the hexagonal ejector rod 103 slidably passes through the lifting ring 84. A secondary rack 104 is slidably arranged between the two fixed strips 61. A number of tooth blocks are arranged on the secondary rack 104. Two tooth springs 105 are connected between the upper part of the secondary rack 104 and the two fixed strips 61. One threaded rod 106 is threadedly connected to each side of the two fixed strips 61 close to each other. A secondary gear 107 is installed at one end of each of the two threaded rods 106 close to each other. Both of the two secondary gears 107 are engaged with a number of tooth blocks on the secondary rack 104. The other ends of the two threaded rods 106 away from each other are respectively located on the sides of the two elastic conductive sheets 62 close to each other.

[0041] It further includes gaskets 11. Gaskets 11 are rotatably installed at the other ends of the two threaded rods 106 through bearings.

[0042] The gaskets 11 are made of insulating material. The two gaskets 11 are respectively in contact with the sides of the two elastic conductive sheets 62 close to each other.

[0043] After the sliding frame 86 drives the horizontal plane on the top piece 87 to move below the two contact rods 85, the two contact rods 85, the lifting ring 84, the six T-shaped frames 83, the twelve sliding strips 81, and the twelve conductive strips 82 no longer move upward. At this time, the sliding frame 86 drives the top piece 87 and the trapezoidal block 101 to continue moving. Since the trapezoidal block 101 is installed on the horizontal plane of the top piece 87, after the lower end of the hexagonal ejector rod 103 contacts the trapezoidal block 101, it drives the hexagonal ejector rod 103 to move upward under the action of the trapezoidal block 101. The guiding ring 102 guides the hexagonal ejector rod 103, and the upper end of the hexagonal ejector rod 103 drives the secondary rack 104 to move upward, and the two tooth springs 105 are stretched accordingly. Under the action of the tooth blocks on the secondary rack 104, the two secondary gears 107 will rotate. The rotation of the two secondary gears 107 drives the two threaded rods 106 to rotate. The two threaded rods 106 rotate and move in a direction away from each other. The two threaded rods 106 drive the two secondary gears 107 to rotate and move in a direction away from each other. The two secondary gears 107 will rotate and move in a direction away from each other on the tooth blocks of the secondary rack 104. The two threaded rods 106 drive the two gaskets 11 to move in a direction away from each other. The two gaskets 11 drive the two elastic conductive sheets 62 to deform and swing and press against two of the conductive strips 82 inserted into the two slots on the two fixing strips 61, so that the contact between the elastic conductive sheet 62 and the conductive strip 82 is closer. The two gaskets 11 are in contact with the two elastic conductive sheets 62, so the two threaded rods 106 will not drive the two gaskets 11 to rotate, thereby reducing the wear of the two elastic conductive sheets 62. And the two gaskets 11 are made of insulating materials, which can effectively avoid signal interference.

[0044] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
