DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0045] Reference Figure 1-Figure 15 A new energy vehicle battery fault detection device includes a lifting component 2 for fixing and lifting a vehicle battery, and also includes a test box 1 for fixing on a wall; wherein the lifting component 2 is fixed on the upper part of the test box 1, and a clamping component 3 is fixedly installed on the lower part of the lifting component 2 through the test box 1, and the clamping component 3 clamps a battery panel 4; wherein the test box 1 is used for closing the door and sealing the power-on test after the lifting component 2 moves the battery panel 4 into the test box 1.

[0046] In the above-mentioned new energy vehicle battery fault detection device, the lifting component 2 is fixed on the upper part of the test box 1, and can realize the vertical lifting operation of the battery. When the battery needs to be tested, the battery plate 4 is firmly clamped by the clamping component 3. The lifting component 2 will move the battery from the outside to the inside of the test box 1 for testing, avoiding exposure of the battery in an open-air environment. The closed design of the test box 1 solves the safety risks of possible battery deflagration and explosion during traditional open-air testing. The closed test box 1 can effectively block the high temperature, flames and fragments generated by the battery explosion, avoiding direct exposure of test personnel to dangerous environments, thereby greatly improving the safety of personnel and equipment.

[0047] The test box 1 is installed on the wall, and its interior is designed as a closed structure. When the lifting component 2 moves the battery panel 4 to the inside of the box 101, the door of the test box 1 will automatically close and form an airtight environment. In this state, the detection equipment in the test box 1 will perform various fault detections on the battery, including battery bulging, temperature abnormalities, internal short circuits, etc. During the detection process, the battery panel 4 is kept stable by the clamping component 3 to ensure the accuracy and safety of the test. The clamping component 3 is installed at the bottom of the lifting component 2 and can firmly clamp the battery panel 4. During the entire detection process, the clamping component 3 keeps the battery panel 4 fixed and does not deform, avoiding inaccurate detection data due to battery movement or vibration. Through the automatic lifting and automatic clamping structure, automated operation is realized, manual intervention is reduced, and the detection efficiency is improved. After the battery is firmly clamped and sent to the test box 1, the test can be started quickly, avoiding errors and risks caused by manual operation.

[0048] In this embodiment, in order to realize the opening and closing function of the door panel 102 of the box body 101 and the fire extinguishing medium injection function, the test box 1 includes a box body 101, and a door panel 102 is slidably installed at the lower opening of the box body 101. The two door panels 102 are movably blocked from the lower opening of the box body 101. Two-way screw rods 103 are rotatably installed inside the two sides of the box body 101, and the two door panels 102 are screwed on the outside of the two sides of the two-way screw rod 103. An injection port 5 for injecting a fire extinguishing medium is provided on the upper part of the box body 101, and a port cover 6 is plugged and installed on the upper part of the injection port 5.

[0049] Rotatable bidirectional screw rods 103 are installed inside the two sides of the box body 101. The two screw rods are connected to the door panels 102 by threads. When the bidirectional screw rod 103 starts to rotate, due to the characteristics of its threaded structure, the two door panels 102 will slide at the same time and open and close along the opening of the box body 101. Specifically, the rotation direction of the bidirectional screw rod 103 determines the movement direction of the door panel 102: when the screw rod rotates in one direction, the door panel 102 will slide in the opposite direction to complete the closing of the box body 101; reverse rotation pushes the door panel 102 to open.

[0050] When the battery panel 4 is placed in the box 101, the door panel 102 is closed, and a closed environment is formed in the box 101 to ensure that the external environment will not affect the test results in the box 101 during the test. Once a battery failure occurs during the test, such as overheating or explosion, the door panel 102 can effectively block it and prevent the spread of external dangers.

[0051] An injection port 5 is provided at the upper part of the box 101 for injecting a fire extinguishing medium into the box 101. This design is very critical, especially for possible battery explosion or fire. When abnormal temperature or explosion is found during battery detection, the injection port 5 can quickly inject a fire extinguishing medium, such as an inert gas or a liquid fire extinguishing agent, so as to control the fire source in time.

[0052] The injection port 5 is equipped with a port cover 6 to prevent debris or dust in the external environment from entering the box body 101. When the fire extinguishing function is needed, the port cover 6 can be quickly opened to facilitate the rapid introduction of the fire extinguishing medium into the box body 101. The design of the port cover 6 ensures the sealing of the test box 1 in the non-testing state, and also has an emergency processing function.

[0053] In this embodiment, in order to realize the driving of the lifting assembly 2, the detection device further includes a driving assembly 7, which drives the lifting assembly 2 to drive the battery panel 4 clamped by the clamping assembly 3 to perform lifting action, and the driving assembly 7 includes a motor 701, which is fixed to the upper part of the box body 101, and a fixing seat 707 is fixedly connected to the upper part of the box body 101, and a lifting gear 704 is rotatably installed inside the fixing seat 707, and the lifting gear 704 is driven by the motor 701 to perform a rotation action. In order to realize the lifting of the battery panel 4, the lifting assembly 2 includes a first tooth plate 201, which is slidably installed on the upper part of the box body 101, and the first tooth plate 201 is meshed and connected with the lifting gear 704, and the lower part of the first tooth plate 201 is fixedly connected to the connecting plate 204, and the lower part of the box body 101 is fixedly connected to the fixing pipe 202, and the lower part of the fixing pipe 202 is fixedly connected to the sliding rod 203, and the lower part of the sliding rod 203 is fixedly connected to the upper part of the connecting plate 204.

[0054] The motor 701 transmits the rotational force to the lifting gear 704 through the fixed seat 707. The design of the fixed seat 707 ensures that the lifting gear 704 can operate stably. The lifting gear 704 is installed inside the fixed seat 707 and is directly driven by the motor 701. When the motor 701 rotates, the lifting gear 704 engages with the first tooth plate 201, driving the first tooth plate 201 to slide up and down. The first tooth plate 201 is installed on the upper part of the box body 101 by sliding and engages with the teeth of the lifting gear 704. The rotation of the gear causes the tooth plate to move linearly in the vertical direction, thereby realizing the lifting operation of the battery panel 4. The sliding path of the tooth plate is controlled by the guide rail inside the box body 101 to ensure its smooth and correct movement. The lower part of the first tooth plate 201 is fixedly connected to the connecting plate 204, and the connecting plate 204 acts as a transmission component to transmit the vertical movement of the lifting tooth plate to the fixed tube 202 at the lower part. The lower part of the fixed tube 202 is fixedly connected with a slide bar 203, and the lower part of the slide bar 203 is connected to the upper part of the connecting plate 204. When the first tooth plate 201 moves upward or downward, the slide bar 203 drives the clamping assembly 3 to move, thereby realizing the lifting operation of the solar panel 4.

[0055] The lower part of the slide bar 203 is connected to the clamping assembly 3, and the clamping assembly 3 firmly clamps the solar panel 4 through the lifting action of the slide bar 203, ensuring that the position of the solar panel 4 is accurate during the lifting process without shaking or offset. The clamping assembly 3 continues to remain stable after the solar panel 4 enters the detection position, ensuring the stability of the solar panel 4 during the test process.

[0056] In this embodiment, in order to achieve the clamping of the battery panel 4, the clamping assembly 3 includes a support plate 301, a connecting plate 204 is fixedly installed on the upper part of the support plate 301, a first bidirectional push rod 302 is fixedly installed on the upper part of both sides of the support plate 301, a cross plate 303 is fixedly connected to both ends of the first bidirectional push rod 302, a second bidirectional push rod 304 is fixedly installed inside the cross plate 303, and a clamping plate 305 for clamping the battery panel 4 is fixedly connected to both ends of the second bidirectional push rod 304. In order to achieve accurate clamping of the battery panel 4, the clamping plate 305 includes a mounting seat 3051, the mounting seat 3051 is fixed to the output end of the second bidirectional push rod 304, a plug plate 3052 is fixedly installed on the lower part of the mounting seat 3051 through a screw 3054, a plug rod 3053 is fixedly connected to the inner side of the plug plate 3052, slots 401 are opened on both sides of the battery panel 4, and the plug rod 3053 is movably plugged into the slots 401.

[0057] The support plate 301 is the core support structure of the clamping assembly 3 and is fixed on the detection device to ensure that the entire clamping system is stable and does not shake during operation. The upper part of the support plate 301 is fixedly mounted with a connecting plate 204 to achieve synchronous lifting.

[0058] The first bidirectional push rod 302 is installed on both sides of the support plate 301, and the two ends of the push rod are respectively connected to the cross plate 303. When the clamping operation is started, the first bidirectional push rod 302 is extended and retracted to drive the cross plate 303 to move left and right. This process adjusts the overall width of the clamping system to accommodate panels 4 of different sizes. The lateral movement of the cross plate 303 ensures that the clamping assembly 3 can be adjusted according to the size of the panel 4, ensuring that the panel 4 can be centered and aligned, and provides preparation for further precise clamping.

[0059] A second bidirectional push rod 304 is installed inside the horizontal plate 303, and both ends of the push rod are respectively connected to the clamping plates 305 for actual clamping. When the second bidirectional push rod 304 contracts, the clamping plates 305 begin to move inward, gradually approaching the two sides of the solar panel 4, and perform the clamping action; when the push rod extends, the clamping plates 305 move outward to release the solar panel 4. The telescopic accuracy of the second bidirectional push rod 304 determines the opening and closing force and stroke of the clamping plates 305, thereby ensuring that the solar panel 4 can be firmly clamped.

[0060] The clamping plate 305 is connected to the plug plate 3052 at the bottom thereof by means of a screw 3054, and a plug rod 3053 is fixed inside the plug plate 3052. When the clamping plate 305 is closed, the plug rod 3053 is movably inserted into the pre-designed slots 401 on both sides of the battery panel 4. The plugging of the plug rod 3053 and the slot 401 realizes the precise positioning and firm fixation of the battery panel 4.

[0061] In order to realize the driving of the lifting gear 704 and the transmission of the first gear 702 and the second gear 703, further, the second gear 703 and the first gear 702 are rotatably mounted on one side of the fixed seat 707, the second gear 703 passes through the fixed seat 707 and is fixedly connected to the lifting gear 704, the second gear 703 is meshed and connected with the first gear 702, and the output end of the motor 701 is fixedly connected to the first gear 702. After the clamping process is completed, the insertion rod 3053 is fully inserted into the slot 401 of the battery panel 4, and the clamping plate 305 remains in a closed state. At this time, the battery panel 4 is firmly locked in the clamping assembly 3 and is connected to the entire lifting assembly 2, ready to enter the detection box 101 for testing.

[0062] In order to realize the dust removal operation of the docking terminal 10, further, a dust removal component 9 is provided on the upper part of the box body 101, and the docking terminal 10 is fixedly installed on the upper part of the box body 101. The battery panel 4 is provided with an external terminal 402. The battery panel 4 is driven to rise by the lifting component 2. At this time, the external terminal 402 is plugged into the docking terminal 10 for electrical connection. The docking terminal 10 is used to connect an external test instrument to detect the battery panel 4. The dust removal component 9 includes a second tooth plate 901, and the second tooth plate 901 slides It is installed on the upper part of the box body 101, and an air cylinder 902 is fixedly installed on the upper part of the box body 101. The driving end of the air cylinder 902 is fixedly connected to the second gear 703, and the second gear plate 901 is meshingly connected to the first gear 702. The output end of the air cylinder 902 is fixedly connected to an air pipe 903, and the end of the air pipe 903 away from the air cylinder 902 is fixedly connected to a spray plate 904, and the spray plate 904 is fixed on the upper part of the box body 101. The lower part of the spray plate 904 is provided with an air jet 905 facing the docking terminal 10.

[0063] When the start button is pressed, the lifting motor 701 starts, driving the lifting assembly 2 to gradually lift the battery panel 4, and the external terminal 402 moves upward to be inserted into the docking terminal 10 located at the upper part of the box 101. At the same time, through the gear transmission, the second tooth plate 901 is driven to slide by the first gear 702 during the lifting process. The sliding of the tooth plate further drives the connected air cylinder 902, so that the air cylinder 902 starts to work.

[0064] The air cylinder 902 works under the drive of the tooth plate to deliver air flow to the spray plate 904, and the air jet 905 below the spray plate 904 sprays gas toward the docking terminal 10. This process is carried out synchronously when the battery panel 4 rises, ensuring that the dust on the surface of the terminal is effectively removed before the external terminal 402 is inserted into the docking terminal 10. The battery panel 4 continues to rise, completing the plug-in connection between the external terminal 402 and the docking terminal 10, and there is no dust in contact, ensuring the accuracy and stability of the detection.

[0065] During the detection operation, the battery panel 4 is lifted by the lifting assembly 2, and the external terminals 402 on the battery panel 4 are plugged into the docking terminals 10 located on the upper part of the box 101 to complete the electrical connection. The docking terminals 10 are interfaces for connecting the battery panel 4 with external detection instruments, through which the fault detection of the battery panel 4 is performed.

[0066] In order to realize the opening and closing of the box door while the motor 701 controls the action of the lifting component 2, and then completes the automatic closing of the box door for detection when the battery panel 4 enters the box body 101, a first linkage gear 705 is rotatably installed on one side of the fixed seat 707, and the first linkage gear 705 is movably meshed and connected with the second tooth plate 901. A linkage rod 706 is fixedly connected to one side of the first linkage gear 705. The detection device also includes a linkage component 8, and the linkage component 8 includes a large rotating wheel 801. The linkage rod 706 is provided with two large rotating wheels 801. The two large rotating wheels 801 are rotatably installed on the upper part of the box body 101, and one end of each linkage rod 706 is fixedly connected to a large rotating wheel 801. Each large rotating wheel 8 01 is fixedly connected with the second linkage gear 802 on one side away from the linkage rod 706, and the two second linkage gears 802 are meshingly connected. The first double-groove wheel 803, the first wheel 806 and the second wheel 807 are also rotatably installed on the upper part of the box body 101. The large wheel 801 is connected to the first double-groove wheel 803 through the first transmission belt 804, and the first double-groove wheel 803 is connected to the first wheel 806 through the second transmission belt 805. One side of the first wheel 806 is fixedly connected to the second wheel 807, and the second wheel 807 is connected to the third wheel 809 through the third transmission belt 808. The second wheel 807 is fixed to one end of the bidirectional screw rod 103.

[0067] When the motor 701 is started, the lifting assembly 2 starts to operate and gradually lifts the solar panel 4. When the solar panel 4 is about to enter the box 101, the drive of the motor 701 not only controls the lifting, but also triggers the opening and closing mechanism of the box door.

[0068] The first linkage gear 705 is movably meshed with the second tooth plate 901, and the upward movement of the battery panel 4 causes the first linkage gear 705 to rotate. At this time, a linkage rod 706 is fixedly connected to one side of the first linkage gear 705, and the linkage rod 706 is driven to move by rotation. One end of each linkage rod 706 is respectively fixedly connected to a large rotating wheel 801 for rotation, and a second linkage gear 802 is fixedly connected to the side of the large rotating wheel 801 away from the linkage rod 706, and the two second linkage gears 802 are meshed with each other. When the large rotating wheel 801 rotates, the second linkage gear 802 rotates accordingly.

[0069] The upper part of the box body 101 is also rotatably mounted with a first double-grooved rotating wheel 803, a first rotating wheel 806, and a second rotating wheel 807. The rotation of the large rotating wheel 801 is connected to the first double-grooved rotating wheel 803 through a first transmission belt 804. The first double-grooved rotating wheel 803 is connected to the first rotating wheel 806 through a second transmission belt 805, the first rotating wheel 806 is fixedly connected to the second rotating wheel 807, and the second rotating wheel 807 is connected to the third rotating wheel 809 through a third transmission belt 808. This transmission system ensures that the power of the motor 701 is effectively transmitted for the opening and closing of the box door.

[0070] When the solar panel 4 completely enters the box body 101 , the linkage assembly 8 drives the box door to close quickly, ensuring the airtightness of the detection environment and facilitating fault detection of the solar panel 4 .

[0071] After the detection is completed, the linkage assembly 8 quickly opens the box door through the reverse action of the motor 701 or the instruction of the control system, so as to facilitate the removal of the solar panel 4 or subsequent operations.
