Description

Technical Field

[0002] Before the battery box leaves the factory, it is often necessary to conduct a power connection test on the battery pack. The traditional detection method is only to install the battery box on the base and make the vehicle socket module and the battery box plug and match, but no power-on detection is performed. Therefore, it can only detect whether the plug-in position of the battery box is correct, resulting in a large number of faulty products, and the subsequent factory return repair is too troublesome. In addition, when the battery box is installed on the base, it is necessary to use lifting equipment to transport the battery box. Traditional lifting equipment often uses the factory crane, and the crane is too time-consuming and labor-intensive for precise lifting. It cannot be applied to large-scale battery box detection, and the top of the battery box needs to be connected to the hook on the crane. This process also requires climbing to the top of the battery box, wasting a lot of workers' time. Summary of the invention

[0049] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0050] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0051] Reference Figures 1 to 10 The charging and discharging detection device and detection method of the heavy-duty truck power battery replacement assembly shown include a vehicle-mounted socket module 5, a battery box 6, a base 7, a locking mechanism 8 and a locking guide body 9, and also include a control console 10 and a lifting device. The control console 10 is electrically connected to the vehicle-mounted socket module 5 through a wire, and the lifting device is located next to the base 7 and is fixedly installed on the ground, and is used to install the battery box 6 on the vehicle-mounted socket module 5.

[0052] The locking mechanism 8 includes two transfer pressing oil cylinders 8a and four linear pushing oil cylinders 8b. The four linear pushing oil cylinders 8b are fixedly mounted on the locking guide body 9, and each two linear pushing oil cylinders 8b are located on one side of the base 7. The working end of each linear pushing oil cylinder 8b is provided with a pressure column, and the two transfer pressing oil cylinders 8a are respectively fixedly mounted on the other two sides of the base 7. The battery box 6 is limited by the linear pushing oil cylinders 8b, and the battery box 6 is pressed down by the two transfer pressing oil cylinders 8a, so that the battery box 6 is tightly pressed on the base 7, avoiding detection failures caused by the gap between the battery box 6 and the base 7.

[0053] The lifting device includes a top frame 3, two pushing mechanisms 1, a horizontal moving mechanism 2 and a clamping device 4. The two horizontal moving mechanisms 2 are respectively located on both sides of the battery box 6. The two horizontal moving mechanisms 2 are fixedly installed on the ground. The two pushing mechanisms 1 are respectively fixedly installed on the two horizontal moving mechanisms 2. The top frame 3 is fixedly installed on the top of the two pushing mechanisms 1. The two clamping devices 4 are fixedly installed on the top frame 3, and the two clamping devices 4 are respectively located on both sides of the top of the battery box 6. When the battery box 6 needs to be installed on the vehicle socket module 5, first, the worker drives the horizontal moving mechanism 2 so that the horizontal moving mechanism 2 drives the clamping device 4 to move to both sides of the top of the battery box 6. After the movement is completed, the worker drives the two clamping devices 4 so that the two clamping devices 4 are clamped on the top of the battery box 6. Then, the worker drives the lifting mechanism 1 so that the two lifting mechanisms 1 push the top frame 3 upward at the same time, so that the top frame 3 drives the two clamping devices 4 to move upward, and then the clamping device 4 drives the battery box 6 to move upward, so that the battery box 6 moves to a specified height, and then the worker drives the horizontal moving mechanism 2 so that the horizontal moving mechanism 2 drives the lifting mechanism 1 to move, and the lifting mechanism 1 drives the top frame 3 to move, so that the battery box 6 moves to the top of the vehicle socket module 5, and then the worker drives the lifting mechanism 1 so that the lifting mechanism 1 drives the clamping device 4 to descend, so that the battery box 6 also descends, and the bottom of the battery box 6 will be clamped on the vehicle socket module 5, thereby completing the installation between the battery box 6 and the vehicle socket module 5;

[0054] Then the worker starts the controller, and the controller performs detection. After the detection is completed, the ascending movement process is repeated to transport the battery box 6 to the ground. After the transportation is completed, the worker drives the clamping device 4 to separate the clamping connection between the clamping device 4 and the battery box 6, thereby completing the removal of the battery box 6;

[0055] Therefore, pulling the pull rope 4f has two effects. First, it drives the plug post 4c to be inserted into the battery box 6 and lock it. Second, it pulls it again to release it, so that the plug post 4c is pulled out of the battery box 6.

[0056] Each clamping device 4 includes a fastening mechanism 4a, a connecting plate 4e, a pull rope 4f, a wire plate 4h, two guide seats 4b, a plug post 4c, a first conflict spring 4j and a cone post 4d. The two guide seats 4b are fixedly mounted on the bottom of the top frame 3. The two plug posts 4c are slidably connected to the two guide seats 4b respectively. The connecting plate 4e is fixedly mounted on one end of the two plug posts 4c. The two cone posts 4d are fixedly mounted on the other ends of the two plug posts 4c respectively. The two first conflict springs 4j are respectively sleeved on the two plug posts 4c. On the plug columns 4c, one end of each first contact spring 4j contacts the guide seat 4b, and the other end contacts the connecting plate 4e. The wire plate 4h is fixedly installed between the two guide seats 4b. One end of the pull rope 4f is fixedly connected to the connecting plate 4e, and the other end of the pull rope 4f passes through the wire plate 4h. The wire plate 4h is provided with a sliding piece for the pull rope 4f to pass through. A pull ring is provided on the other end of the pull rope 4f. The fastening mechanism 4a is fixedly installed on the lifting mechanism 1, and is used to position and lock the connecting plate 4e. When it is necessary to clamp the clamping device 4 and the battery box 6, the worker pulls the pull rope 4f, so that the pull rope 4f pulls the connecting plate 4e to move toward the guide seat 4b, so that the connecting plate 4e drives the two plugging posts 4c to be inserted into the battery box 6. The cone column 4d is used to prevent the burrs on the square tube of the battery box 6 from blocking the plugging posts 4c during the movement of the plugging posts 4c. When the plugging posts 4c are inserted, the fastening mechanism 4a locks the connecting plate 4e, so that the plugging posts 4c cannot be reset, thereby completing the clamping of the clamping device 4 and the battery box 6. The first resistance spring 4j is used to make the connecting plate 4e have a reset thrust, so as to prepare for the subsequent reset.

[0057] When the clamping device 4 needs to be separated from the battery box 6, the worker only needs to pull the pull rope 4f again, and the fastening mechanism 4a will automatically release the clamping between the connecting plate 4e.

[0058] Each fastening mechanism 4a includes a one-way clamping mechanism, a fixed cone 4a1, a sliding cone 4a2, a mounting column 4a3, a mounting tube 4a4 and a limiting circular plate 4a5. The one-way clamping mechanism is fixedly mounted on the connecting plate 4e, the mounting tube 4a4 is fixedly mounted on the lifting mechanism 1, one end of the mounting column 4a3 is fixedly mounted on the mounting tube 4a4, the limiting circular plate 4a5 is fixedly mounted on the other end of the mounting column 4a3, the fixed cone 4a1 is fixedly mounted on the mounting column 4a3, a sliding hole is opened in the middle of the sliding cone 4a2, and the sliding cone 4a2 is slidably connected to the mounting column 4a3. When the connecting plate 4e moves forward, the connecting plate 4e will drive the one-way clamping mechanism to move, so that the one-way clamping mechanism moves along the inclined surface of the fixed cone 4a1, so that the one-way clamping mechanism passes through the fixed cone 4a1. After passing through, the one-way clamping mechanism will abut against the plane of the fixed cone 4a1, so that the connecting plate 4e cannot move, thereby completing the fixing of the connecting plate 4e.

[0059] When the clamping device 4 needs to be separated from the battery box 6, the worker only needs to pull the pull rope 4f again, and the pull rope 4f will drive the connecting plate 4e to continue to move forward, so that the connecting plate 4e drives the one-way clamping mechanism to move forward, and the inclined surface of the triangular clamping plate 4a6 will contact the sliding cone 4a2, so that the triangular clamping plate 4a6 is pushed upward, and then the triangular clamping plate 4a6 passes through the sliding cone 4a2. After passing through, the worker releases the pull rope 4f. Due to the elastic force of the first contact spring 4j, the triangular clamping plate 4a6 will push the sliding cone 4a2 to move toward the fixed cone 4a1. When the sliding cone 4a2 is moved, the worker will release the pull rope 4f. After a2 is fitted with the fixed cone 4a1, the first resistance spring 4j will continue to push the triangular clamp plate 4a6, so that the triangular clamp plate 4a6 moves along the inclined surface of the sliding cone 4a2, so that the triangular clamp plate 4a6 moves upward. When the triangular clamp plate 4a6 passes through the sliding cone 4a2, since the sliding cone 4a2 is fitted with the fixed cone 4a1, the triangular clamp plate 4a6 will also pass through the fixed cone 4a1. In order to avoid the sharp corners of the triangular clamp plate 4a6 from being inserted between the sliding cone 4a2 and the fixed cone 4a1, the sharp corners of the triangular clamp plate 4a6 can be ground into a plane or an arc.

[0060] Each one-way clamping mechanism includes a triangular clamping plate 4a6, a guide plate 4a8, two first guide pillars 4a7 and a second conflicting spring 4a9. The guide plate 4a8 is fixedly mounted on the connecting plate 4e. One ends of the two first guide pillars 4a7 pass through the guide plate 4a8. The guide plate 4a8 is provided with guide holes for the first guide pillars 4a7 to pass through. The triangular clamping plate 4a6 is fixedly mounted on the bottom ends of the two first guide pillars 4a7. A limiting plate is provided on the top ends of the two first guide pillars 4a7. The two second conflicting springs 4a9 are respectively sleeved on the two first guide pillars 4a7. One end of each second conflicting spring 4a9 conflicts with the guide plate 4a8, and the other end conflicts with the triangular clamping plate 4a6. When the triangular clamp plate 4a6 contacts the inclined surface of the fixed cone 4a1, or the inclined surface of the triangular clamp plate 4a6 contacts the plane of the sliding cone 4a2, the triangular clamp plate 4a6 will move upward. When the triangular clamp plate 4a6 moves upward, the triangular clamp plate 4a6 will compress the second interference spring 4a9, and the first guide column 4a7 will slide along the sliding hole of the guide plate 4a8. Of course, the second interference spring 4a9 can also be removed, and the triangular clamp plate 4a6 can be lowered by the gravity of the triangular clamp plate 4a6.

[0061] Each push-up mechanism 1 includes an electric push rod 1a, a first support frame 1b, two second guide columns 1c and a linear bearing 1d. The two linear bearings 1d are fixedly mounted on the horizontal moving mechanism 2. The two second guide columns 1c are respectively slidably connected to the two linear bearings 1d. The tops of the two second guide columns 1c are fixedly connected to the first support frame 1b. The electric push rod 1a is fixedly mounted on the first support frame 1b, and the output end of the electric push rod 1a contacts the top of the horizontal moving mechanism 2. The controller controls the electric push rod 1a to work, so that the output end of the electric push rod 1a pushes downward, so that the output end of the electric push rod 1a contacts the top of the horizontal moving mechanism 2, so that the electric push rod 1a drives the first support frame 1b to move upward, and the first support frame 1b drives the second guide column 1c to slide along the linear bearing 1d.

[0062] The horizontal moving mechanism 2 includes a second support frame 2b, an angle iron 2c and three wheels 2a. The angle iron 2c is fixedly mounted on the ground. The three wheels 2a are fixedly mounted on the bottom of the second support frame 2b, and the three wheels 2a are clamped on the angle iron 2c. Two linear bearings 1d are fixedly mounted on the second support frame 2b. When the battery box 6 is lifted, the worker pushes the second support frame 2b, so that the second support frame 2b drives the wheels 2a to slide along the angle iron 2c, thereby completing the horizontal transportation of the battery box 6. The equipment can also be used to replace manual pushing.

[0063] The detection method of the charge and discharge detection device of the heavy-duty truck power replacement battery assembly comprises the following steps:

[0064] Step 1: Install the battery box 6;

[0065] The battery box 6 is lifted onto the base 7 by means of a lifting device, and the four sets of male plugs on the battery box 6 are plugged and matched with the four sets of female sockets on the vehicle socket module 5;

[0066] Step 2: Power on test;

[0067] The device is powered on through the console 10, and the display screen of the console 10 will display the terminal connection status between the four groups of female sockets and the four groups of male plugs;

[0068] Step 3: Test structure analysis;

[0069] If the four groups of female socket simulation images on the display screen are all green, it means that the battery box 6 is qualified;

[0070] If one of the four female socket simulation images on the display screen is bright red, it means that the male plug at the corresponding position is damaged;

[0071] Step 4: Unloading and maintenance;

[0072] The battery box 6 is removed by a lifting device, and then a worker repairs a set of male plugs at a designated position.

[0073] Working principle: when the battery box 6 needs to be installed on the vehicle socket module 5, first, the worker drives the horizontal moving mechanism 2 so that the horizontal moving mechanism 2 drives the clamping device 4 to move to both sides of the top of the battery box 6. After the movement is completed, the worker drives the two clamping devices 4 so that the two clamping devices 4 are clamped on the top of the battery box 6. Then, the worker drives the lifting mechanism 1 so that the two lifting mechanisms 1 push the top frame 3 upward at the same time, so that the top frame 3 drives the two clamping devices 4 to move upward, and then the clamping device 4 drives the battery box 6 to move upward, so that the battery box 6 moves to a specified height, and then the worker drives the horizontal moving mechanism 2 so that the horizontal moving mechanism 2 drives the lifting mechanism 1 to move, and the lifting mechanism 1 drives the top frame 3 to move, so that the battery box 6 moves to the top of the vehicle socket module 5, and then the worker drives the lifting mechanism 1 so that the lifting mechanism 1 drives the clamping device 4 to descend, and then the battery box 6 also descends, and the bottom of the battery box 6 will be clamped on the vehicle socket module 5, thereby completing the installation between the battery box 6 and the vehicle socket module 5;

[0074] Then the worker starts the controller, and the controller performs detection. After the detection is completed, the ascending movement process is repeated to transport the battery box 6 to the ground. After the transportation is completed;

[0075] The worker pulls the pull rope 4f again, and the pull rope 4f will drive the connecting plate 4e to continue to move forward, so that the connecting plate 4e drives the one-way clamping mechanism to move forward, and the inclined surface of the triangular clamping plate 4a6 will contact the sliding cone 4a2, so that the triangular clamping plate 4a6 is pushed upward, and then the triangular clamping plate 4a6 passes through the sliding cone 4a2. After passing through, the worker releases the pull rope 4f. Due to the elastic force of the first contact spring 4j, the triangular clamping plate 4a6 will push the sliding cone 4a2 to move toward the fixed cone 4a1. After the cone 4a2 fits with the fixed cone 4a1, the first resistance spring 4j will continue to push the triangular clamping plate 4a6, so that the triangular clamping plate 4a6 moves along the inclined surface of the sliding cone 4a2, so that the triangular clamping plate 4a6 moves upward. When the triangular clamping plate 4a6 passes through the sliding cone 4a2, since the sliding cone 4a2 fits with the fixed cone 4a1, the triangular clamping plate 4a6 will also pass through the fixed cone 4a1, so that the plug 4c is pulled out from the battery box 6, thereby completing the separation between the battery box 6 and the clamping device 4.
