[0036] The utility model discloses a movable electric automobile battery replacement platform, its structure is as shown in

[0037] The utility model discloses a movable electric automobile battery replacement platform, its structure is as shown in Figure 1 In a preferred embodiment, the first drive mechanism 3 includes a lead screw 31 and a first motor 32, the first motor 32 is installed on the base 1, the lead screw 31 is connected to the output shaft of the first motor 32, the lead screw 31 extends along the length direction of the base 1, and the lead screw 31 passes through the sliding table 2 and is threadedly connected with the sliding table 2.

[0038] In use, when the first motor 32 is powered on, the motor output shaft starts to rotate, the lead screw 31 is connected to the output shaft of the first motor 32 and rotates synchronously with the output shaft.

[0039] ​In order to provide a guide for the movement of the sliding table 2, please refer to Figure 1 In a preferred embodiment, the first driving mechanism 3 further comprises a guide rail 33 and a guide block 34, the guide rail 33 is connected to the base 1, the guide rail 33 extends along the length direction of the base 1, the guide block 34 is connected to the sliding table 2, and the guide block 34 is slidingly connected to the guide rail 33.

[0040] In use, the guide rail 33 is fixedly installed on the base 1 and extends along the length direction of the base 1 to provide a direction guide for the movement of the sliding table 2. The guide block 34 is connected to the sliding table 2 and is sleeved on the guide rail 33. When the sliding table 2 has a tendency to move under the action of the first driving mechanism 3, the guide block 34 will slide along the guide rail 33. The guide block 34 can only move in the direction defined by the guide rail 33, thereby ensuring that the sliding table 2 always moves linearly along the length direction of the base 1, avoiding the sliding table 2 from deviating during movement, and ensuring the linearity and stability of the movement.

[0041] In order to limit the sliding table 2, please refer to Figure 1 In a preferred embodiment, the first driving mechanism 3 further comprises a baffle 35, two baffles 35 are respectively connected to the two ends of the base 1, the baffle 35 is used to abut against the guide block 34, the first motor 32 is installed on the baffle 35, and the screw rod 31 is rotatably connected to the baffle 35.

[0042] In use, the two baffles 35 are respectively installed at the two ends of the base 1. When the sliding table 2 moves along the guide rail 33 under the action of the screw rod 31, the guide block 34 connected to the sliding table 2 also moves. When the guide block 34 moves close to the two ends of the base 1, it will abut against the baffle 35. This abutment plays a limiting role, preventing the sliding table 2 from falling off the base 1 due to the continuous rotation of the screw rod 31, and improving the safety.

[0043] In order to drive the lifting platform 4 to lift, please refer to Figure 2 In a preferred embodiment, the second driving mechanism 5 comprises a hydraulic cylinder 51 and a hydraulic station 52, the hydraulic station 52 is connected to the hydraulic cylinder 51, the fixed end of the hydraulic cylinder 51 is connected to the sliding table 2, and the movable end of the hydraulic cylinder 51 is connected to the lifting platform 4.

[0044] In use, the hydraulic station 52 is the power source, which sucks the hydraulic oil from the oil tank and pressurizes the hydraulic oil to have a certain pressure. The pressurized hydraulic oil is delivered to the hydraulic cylinder 51 through the oil pipe to provide power for the work of the hydraulic cylinder 51. When the hydraulic oil enters the oil cavity of the hydraulic cylinder 51, the piston is subjected to an outward thrust under the action of the hydraulic oil pressure, which pushes the piston rod to extend, thereby driving the lifting platform 4 to move upward. When the lifting platform 4 needs to be lowered, the hydraulic oil flows out of the oil cavity of the hydraulic cylinder 51, so that the piston is subjected to a reverse force, the piston rod is retracted, and the lifting platform 4 is lowered accordingly.

[0045] In order to improve the stability of the lifting platform 4, please refer to Figure 2 In a preferred embodiment, the second driving mechanism 5 further comprises a scissor arm, the scissor arm comprising a first arm 53 and a second arm 54, one end of the first arm 53 and the second arm 54 being hinged to the sliding table 2, the other end of the first arm 53 and the second arm 54 being hinged to the lifting platform 4, the middle part of the first arm 53 and the second arm 54 being hinged, the cylinder body of the hydraulic cylinder 51 being hinged to the sliding table 2, and the piston rod of the hydraulic cylinder 51 being hinged to the first arm 53 or the second arm 54.

[0046] In use, taking the case that the piston rod is hinged to the first arm 53 as an example, since the cylinder body of the hydraulic cylinder 51 is hinged to the sliding table 2, when the piston rod extends or retracts, it will push the first arm 53 to rotate around the hinge point, and the rotation of the first arm 53 will drive the second arm 54 to move synchronously. The included angle between the two arms will change with the movement of the piston rod, thereby causing the overall expansion or contraction of the scissor arm. The expansion and contraction of the scissor arm directly drives the lifting platform 4 to move along the height direction of the sliding table 2. When the scissor arm expands, the included angle between the two arms increases, which pushes the lifting platform 4 to rise; when the scissor arm contracts, the included angle decreases, and the lifting platform 4 descends.

[0047] In order to further improve the stability of the lifting platform 4, please refer to Figure 2 In a preferred embodiment, the second driving mechanism 5 further comprises a cantilever beam 55, the cantilever beam 55 being hinged between two oppositely arranged first arms 53, and the piston rod of the hydraulic cylinder 51 being hinged to the cantilever beam 55.

[0048] In use, the two oppositely arranged first arms 53 are connected by the cantilever beam 55 to form a stable triangular structure. When the piston rod of the hydraulic cylinder 51 acts on the cantilever beam 55, the force generated can be uniformly and stably transmitted to the two first arms 53. This ensures that the scissor arm structure is uniformly stressed during lifting, effectively reducing the risk of structural deformation or tilting caused by unilateral stress.

[0049] In order to monitor the rising height of the lifting platform 4, please refer to Figure 2In a preferred embodiment, the second driving mechanism 5 further comprises a pressure sensing pad 56, which is connected to the lifting platform 4 and used to contact the battery.

[0050] In use, when the lifting platform 4 is ascending, the pressure sensing pad 56 is pressed by the battery as it is located at the top of the lifting platform 4. The pressure sensing pad 56 converts the pressure into an electric signal, and the lifting platform 4 stops ascending upon receiving the electric signal. The dismounting mechanism 6 starts working.

[0051] For the convenience of dismounting the bolt, please refer to Figure 3 With Figure 4 In a preferred embodiment, the dismounting mechanism 6 comprises a sleeve 61, a second motor 62, a jacking plate 63 and a spring 64. The second motor 62 is installed on the lifting platform 4. The sleeve 61 is connected to the output shaft of the second motor 62 and used to be sleeved on the nut of the bolt. The jacking plate 63 is slidingly connected to the sleeve 61 along the height direction of the sleeve 61. One end of the spring 64 is connected to the jacking plate 63, and the other end of the spring 64 is connected to the bottom of the sleeve 61. The spring 64 is in a compressed state and makes the jacking plate 63 tend to slide towards the top of the sleeve 61.

[0052] In use, when dismounting, the lifting platform 4 continues to ascend, and the sleeve 61 is accurately sleeved on the nut of the bolt. The second motor 62 is started, and the output shaft drives the sleeve 61 to rotate. Since the sleeve 61 is tightly sleeved on the nut, the rotating force of the sleeve 61 is transmitted to the nut, so that the bolt starts to rotate. With the rotation of the bolt, it gradually exits from the mounting hole of the battery. When mounting, the bolt to be mounted is placed in the sleeve 61, and the jacking plate 63 is lifted by the spring 64 to make the head of the bolt flush with the top of the sleeve 61, so as to facilitate the alignment of the mounting hole of the battery. The second motor 62 is reversely rotated to drive the sleeve 61 and the bolt to rotate together, and the bolt is gradually screwed into the mounting hole. In the process of screwing the bolt, the pressure of the spring 64 always applies a certain axial force to the bolt to assist the tightening of the bolt and ensure the firm installation of the bolt. When the bolt is tightened to a certain extent, the motor stops working, and the installation of the bolt is completed.

[0053] For the convenience of sliding the bolt into the sleeve 61, please refer to Figure 4 In a preferred embodiment, the opening of the sleeve 61 is provided with a circular arc chamfer.

[0054] In use, the sleeve 61 is accurately sleeved on the nut of the bolt during bolt dismounting operation. Due to the possible position deviation in actual operation, the bolt and the sleeve 61 are difficult to be completely accurately aligned. However, the existence of the circular arc chamfer enables the bolt to be smoothly slid into the sleeve 61 even if there is a certain angle or position deviation, thereby reducing the difficulty of sleeving.

[0055] In order to better understand the present application, the following will be combined with Figure 1 Figure 4 The working principle of the technical scheme of the movable electric vehicle battery replacement platform of the present application is described in detail as follows: the first driving mechanism 3 is started, and the movable end drives the sliding table 2 to slide along the length direction of the base 1. The position of the sliding table 2 on the base 1 can be adjusted, and the lateral position required for the vehicle to stop can be accurately positioned. When the position of the sliding table 2 is determined, the second driving mechanism 5 works, and the movable end drives the lifting platform 4 to slide along the height direction of the sliding table 2. When the lifting platform 4 reaches the appropriate height, the dismounting mechanism 6 is started to dismount or install the fixing bolt of the battery, thereby completing the replacement of the battery.

[0056] The specific implementation mode of the present application described above does not constitute a limitation on the protection scope of the present application. Any various other corresponding changes and modifications made according to the technical concept of the present application shall be included in the protection scope of the claims of the present application.​
