DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0031] A battery replacement auxiliary device for new energy vehicles, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a first screw rod 2, a first synchronous belt assembly 3, a servo motor 4, a placement mechanism 5 and a disassembly mechanism 6. The servo motor 4 is connected to the upper right side of the mounting base 1 by bolts. The output shaft of the servo motor 4 is set to the left. The first synchronous belt assembly 3 is connected to the output shaft of the servo motor 4. The first synchronous belt assembly 3 includes two first synchronous wheels and a first synchronous belt. The right ends of the first screw rods 2 are connected to the first synchronous wheels, and the first synchronous belt is wound around the first synchronous wheels. Two first screw rods 2 are rotatably connected to the bottom of the mounting base 1. The first screw rods 2 are connected to the first synchronous belt assembly 3. A placement mechanism 5 is provided between the two first screw rods 2 for placing the new energy vehicle battery. A disassembly mechanism 6 is provided on the placement mechanism 5 for assisting in the disassembly and replacement of the new energy vehicle battery.

[0032] When disassembling and replacing the battery of a new energy vehicle, this device can be used for auxiliary assistance. First, start the servo motor 4. The output shaft of the servo motor 4 drives the first synchronous belt assembly 3 to operate, so that the first screw rod 2 rotates. During the rotation of the first screw rod 2, the placement mechanism 5 moves to the left. The operator disassembles the original battery of the new energy vehicle by controlling the disassembly mechanism 6. Then, the output shaft of the servo motor 4 is controlled to rotate in the opposite direction, so that the placement mechanism 5 slides to the right and resets. Then, a new electromagnet is placed on the placement mechanism 5. Repeat the above operation to feed the new battery in. The battery can be installed through the disassembly mechanism 6, thereby achieving the effect of quickly disassembling and replacing the battery of the new energy vehicle.

[0033] like Figure 1 and Figure 3 As shown, the placement mechanism 5 includes a movable base 51, a hydraulic cylinder 52 and a placement platform 53. The movable base 51 is threadedly connected between the two first screw rods 2. Four hydraulic cylinders 52 are connected to the top of the movable base 51. The placement platform 53 is connected between the tops of the telescopic ends of the four hydraulic cylinders 52. The placement platform 53 is used to place and support the new energy vehicle battery.

[0034] When replacing the battery of the new energy vehicle, the output shaft of the servo motor 4 is controlled to drive the first synchronous belt assembly 3 to operate, so that the first screw rod 2 rotates, and then the movable base 51 slides to the left, and then the telescopic ends of the hydraulic cylinder 52 are controlled to extend upward, so that the placement table 53 moves upward, and then the disassembled old battery is placed on the placement table 53, and then the telescopic ends of the hydraulic cylinder 52 are controlled to retract and reset downward, and then the output shaft of the servo motor 4 is controlled to drive the first synchronous belt assembly 3 to rotate in the opposite direction, so that the first screw rod 2 rotates in the opposite direction, and then the movable base 51 slides to the right, and the operator removes the old battery and places the new battery on the placement table 53, and then repeats the above operation to send the core battery to the bottom of the new energy vehicle for replacement. In summary, the first screw rod 2 is driven to rotate by the output shaft of the servo motor 4, so that the movable base 51 drives the placement table 53 to move, thereby quickly replacing the battery of the new energy vehicle and improving the replacement efficiency.

[0035] like Figure 1 、 Figure 4 and Figure 5As shown, the disassembly mechanism 6 includes a detection camera 61, a dual-axis motor 62, a first rotating shaft 63, a second synchronous belt assembly 64, a second screw rod 65, a movable plate 66, a lifting plate 67, a disassembly device 68 and a spring 69. The placement table 53 is evenly connected with the detection camera 61 by bolts. The detection camera 61 is used to take pictures and detect the bottom of the new energy vehicle. Each side of the placement table 53 is connected with a dual-axis motor 62 by bolts. The output shaft of the dual-axis motor 62 is connected to the first rotating shaft 63. The placement table 53 is evenly rotatably connected with the second screw rod 65. The second synchronous belt assembly 64 is connected between the second screw rod 65 and the first rotating shaft 63. The second synchronous belt assembly 64 includes a second synchronous wheel and a second synchronous wheel. The step belt and the first rotating shaft 63 are connected to the second synchronous wheel, and the second synchronous belt is wound around the two second synchronous wheels close to each other. Two movable plates 66 are threadedly connected to the second screw rods 65 on each of the front and rear sides, and three movable plates 66 are threadedly connected to the second screw rods 65 on the left and right sides. The movable plates 66 are all slidably connected to the placement table 53, and the top of the movable plate 66 is slidably connected to the lifting plate 67. Two springs 69 are connected between the lifting plate 67 and the movable plate 66. The top of the spring 69 is connected to the lifting plate 67, and the bottom of the spring 69 is connected to the movable plate 66. The top of the lifting plate 67 is connected to the lifting plate 67, and the bottom of the spring 69 is connected to the movable plate 66. The top of the lifting plate 67 is connected to the disassembly device 68, which is used to disassemble the mounting screws on the new energy vehicle battery.

[0036] When replacing the battery of the new energy vehicle, as the mobile base 51 drives the placement table 53 to slide to the left, the detection camera 61 will also move to the left. The operator observes the bottom of the new energy vehicle through the detection camera 61, and then starts the dual-axis motor 62 to make the first rotating shaft 63 rotate. The rotation of the first rotating shaft 63 will cause the second synchronous belt assembly 64 to operate, thereby causing the second screw rod 65 to rotate, and then causing the movable plate 66 to slide, so that the disassembly device 68 can be aligned with the installation screws, and then turn off the dual-axis motor 62. As the telescopic ends of the hydraulic cylinder 52 extend upward, the disassembly device 68 will dock with the installation screws, so that the lifting plate 67 will slide downward, and the spring 69 will be compressed. Then the disassembly device 68 is controlled to remove the installation screws, so that the old battery falls on the placement table 53, and then as the placement The platform 53 moves downward to reset, and under the action of the spring 69, the lifting plate 67 will slide upward to reset, and then as the mobile base 51 moves to the right, the operator needs to remove the old battery and place the new battery on the placement platform 53, and then repeat the above operation to send the new battery to the bottom of the new energy vehicle, and then install it by controlling the disassembly mechanism 6 mounting screws, thereby realizing the installation of the new energy vehicle battery. In summary, the bottom of the new energy vehicle is observed by the detection camera 61, and then the dual-axis motor 62 is controlled to enable the disassembly device 68 to be aligned with the battery mounting screws, and then the mounting screws are removed by the disassembly mechanism 6 to achieve the effect of quickly removing the mounting screws, avoiding the operator from entering the bottom of the vehicle to remove the mounting screws, and then the mounting screws are installed by the disassembly device 68, thereby achieving the effect of installing the new energy vehicle battery.

[0037] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, it also includes a trigger mechanism 7, which includes a support seat 71, a second rotating shaft 72, a third rotating shaft 73, a first sliding frame 74, a second sliding frame 75 and a connecting piece 76. The top of the movable base 51 is connected to the support seat 71 by bolts, and the second rotating shaft 72 is rotatably connected to the support seat 71. The second rotating shaft 72 has a knob, and the knob facilitates people to rotate the second rotating shaft 72. The top of the second rotating shaft 72 is connected to the third rotating shaft 73, and four first sliding frames 74 are slidably connected to the inside of the placement table 53. The first sliding frames 74 are all slidably connected to the third rotating shaft 73, and the first sliding frames 74 are all connected to the second sliding frames 75. The bottom of the lifting plate 67 is connected to two connecting pieces 76, and the connecting pieces 76 can be squeezed and limited by the second sliding frames 75.

[0038] After the disassembly devices 68 are aligned with the battery mounting screws, as the placement table 53 moves upward, people can rotate the second rotating shaft 72, thereby rotating the third rotating shaft 73, so that the first sliding frame 74 slides to the side close to the third rotating shaft 73, and then pulls the second sliding frame 75 to move to the side close to the third rotating shaft 73, so that the connecting members 76 are no longer squeezed by the second sliding frame 75. At this time, in the initial state, the springs 69 are in a state of force compression. When the connecting members 76 are no longer squeezed, under the action of the springs 69, the lifting plates 67 will drive the connecting members 76 to move upward, thereby driving the disassembly device 68 to move upward and dock with the battery mounting screws. After the disassembly is completed, it rotates in the opposite direction. The second rotating shaft 72 causes the third rotating shaft 73 to rotate in the opposite direction, thereby causing the first sliding frame 74 to slide to the side away from the third rotating shaft 73. The first sliding frame 74 will push the second sliding frame 75 to slide to the side away from the third rotating shaft 73, thereby squeezing and pushing the connecting member 76, so that the connecting member 76 drives the lifting plate 67 to slide downward and reset, and the spring 69 is compressed. In summary, by rotating the second rotating shaft 72, the third rotating shaft 73 is rotated, and the first sliding frame 74 pulls the second sliding frame 75 to move, so that the connecting member 76 is no longer restricted. Under the action of the spring 69, the disassembly device 68 can move upward and dock with the battery mounting screws, making it easy to remove the mounting screws.

[0039] like Figure 1 and Figure 9 As shown, it also includes a rotating mechanism 8, which includes a fixed seat 81, a fixed frame 82, a fourth rotating shaft 83, a fifth rotating shaft 84 and a bevel gear 85. The upper right side of the movable base 51 is connected to the fixed seat 81 by bolts, and the right side of the movable base 51 is connected to the fixed frame 82 by bolts. The fourth rotating shaft 83 is rotatably connected to the fixed seat 81, and the fifth rotating shaft 84 is slidably connected to the fourth rotating shaft 83. The fifth rotating shaft 84 is rotatably and slidably connected to the fixed frame 82. Rotating the fifth rotating shaft 84 can drive the fourth rotating shaft 83 to rotate. The left part of the fourth rotating shaft 83 is connected to the bevel gear 85, and the bottom of the second rotating shaft 72 is also connected to the bevel gear 85. The two bevel gears 85 are meshed with each other.

[0040] When the second rotating shaft 72 needs to be rotated, the fifth rotating shaft 84 can be pulled to the right according to the length of the operator's arm, and then the fifth rotating shaft 84 can be rotated to rotate the fourth rotating shaft 83. The rotation of the fourth rotating shaft 83 will drive the lower bevel gear 85 to rotate, thereby rotating the upper bevel gear 85, and then rotating the second rotating shaft 72. The second rotating shaft 72 is rotated by rotating the fifth rotating shaft 84, which is convenient for the operator to operate, and the operator no longer needs to enter the bottom of the vehicle to operate. In summary, the fourth rotating shaft 83 is rotated by rotating the fifth rotating shaft 84, and the second rotating shaft 72 is rotated under the action of the bevel gear 85. The operator no longer needs to enter the bottom of the vehicle to perform the rotation operation, which improves operational safety.

[0041] like Figure 1 and Figure 10 As shown, it also includes a step mechanism 9, which includes a first step 91 and a second step 92. The second steps 92 are connected to the front and rear sides of the left side of the mounting base 1. The left side of the mounting base 1 is slidably connected to two first steps 91, and the first steps 91 can be spliced with the corresponding second steps 92, so as to facilitate the driving of new energy vehicles.

[0042] In order to facilitate battery replacement for new energy vehicles, the first steps 91 can be pulled to the side away from each other, so that the first steps 91 are spliced with the second steps 92. At this time, the operator can drive the car by the guidance of the first steps 91 and the second steps 92, so that the device can be directly located at the bottom of the car, and no additional moving device is needed to cause inconvenience.

[0043] like Figure 1 and Figure 11 As shown, it also includes a positioning mechanism 10, which includes a positioning frame 101 and a blocking seat 102. The positioning frame 101 is connected to the left side of the mobile base 51, and the blocking seat 102 is slidably connected to the rear side of the positioning frame 101. The blocking seat 102 is used to limit the wheel.

[0044] Pull the blocking seat 102 backward, and then after the new energy vehicle passes through the guidance of the first step 91 and the second step 92, as the wheels contact the blocking seat 102, it indicates that the vehicle has been parked in the designated position. At this time, there is no need to operate the vehicle anymore. When the battery replacement is completed, as the vehicle leaves the device, push the blocking seat 102 forward to reset it.

[0045] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention.
