DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figures 1 to 3 , the utility model provides a technical solution:

[0023] A battery exchange device based on an integrated photovoltaic, storage, charging and swapping station for electric vehicles includes a T-shaped guide rail 1, a lifting device 2, an adjustment device 3, a gripping device 4 and a battery transfer mechanism 5. The T-shaped guide rail 1 is composed of two mutually perpendicular guide rails. The lifting device 2 and the battery transfer mechanism 5 are movably arranged on the two mutually perpendicular guide rails of the T-shaped guide rail 1. The device is characterized in that:

[0024] The adjusting device 3 is arranged at the lifting end of the lifting device 2. The adjusting device 3 includes a mounting plate 31, a worm wheel 32, a worm 33, a mounting block 34, a linear guide 35, a movable guide 36, a toothed frame 37 and a gear 38. The worm wheel 32 is rotatably mounted on the mounting plate 31, wherein the worm wheel 32 is rotatably mounted on the slider, and the slider is mounted on the mounting plate 31. The two worms 33 are rotatably mounted on the mounting plate 31 through the mounting block 34 and are respectively engaged with the two sides of the worm wheel 32, wherein the worm 33 is driven by a motor, and the two linear guides 35 are arranged opposite to each other and are placed horizontally on the mounting plate 31. The movable guide 36 is movably mounted on the linear guide 35, wherein the movable guide The guide direction of the guide rail 36 is perpendicular to that of the linear guide rail 35. A rack is provided on the inner side of the long side of the toothed frame 37. The toothed frame 37 is movably mounted on the movable guide rail 36 and meshes with a gear 38. The gear 38 is located directly above the worm gear 32. When the two worms 33 rotate in different directions, the two worms 33 rotate, which in turn drives the worm gear 32 to rotate. The rotation of the worm gear 32 drives the gear 38 to rotate. The rotation of the gear 38 drives the toothed frame 37 to move perpendicular to the rotation center of the worms 33 through the rack on the toothed frame 37. At the same time, changing the rotation direction of the two worms 33 can also change the rotation direction of the worm gear 32, thereby changing the movement direction of the toothed frame 37. When the two worms 33 rotate in the same direction, the circumferential forces exerted by the two worms 33 on the worm gear 32 will cancel each other out, while the radial forces are in the same direction and the sum of the two radial forces is greater than the friction force of the slider on the worm gear 32 on the mounting plate 31. Therefore, the worm gear 32 no longer rotates but moves along the vortex groove on the worm gear 32.

[0025] The grabbing device 4 is fixedly arranged on the toothed frame 37. The movement of the toothed frame 37 drives the grabbing device 4 to move synchronously.

[0026] As a preferred embodiment, the lifting device 2 and the battery transfer mechanism 5 are driven by a linear drive assembly to move linearly on the T-shaped guide rail 1. The linear movement of the lifting device 2 and the battery transfer mechanism 5 on the T-shaped guide rail 1 is a conventional technical means for those skilled in the art, and its driving scheme and principle will not be elaborated here.

[0027] As a preferred embodiment, the guide of the linear guide 35 is in the same vertical plane as the rotation center of the worm 33. When the two worms 33 rotate in the same direction, the circumferential forces exerted by the two worms 33 on the worm wheel 32 cancel each other out, while the radial forces are in the same direction and the sum of the two radial forces is greater than the friction force of the worm wheel 32 on the mounting plate 31. Therefore, the worm wheel 32 no longer rotates but moves along the vortex groove on the worm wheel 32. The worm wheel 32 also drives the movable guide 36 to move linearly along the linear guide 35, which in turn drives the toothed frame 37 to move synchronously. At the same time, changing the rotation direction of the two worms 33 can also change the movement direction of the worm wheel 32, and thus change the movement direction of the toothed frame 37.

[0028] As a preferred embodiment, the grabbing device 4 includes a support plate 41 and a grabbing rod 42. The support plate 41 is fixedly set on the toothed frame 37, and at least one grabbing rod 42 is set on the support plate 41. When the lifting device 2 is used to insert the grabbing rod 42 into the battery slot, the T-shaped guide rail 1 drives the grabbing device 4 to move toward the battery transfer mechanism. At this time, the battery is pulled out from the electric car with the movement of the grabbing device 4. After obtaining the new battery, the new battery is inserted into the electric car, and then the lifting device 2 is used to pull the grabbing rod 42 out of the battery slot. At this time, the new battery is installed. As a preferred embodiment, the battery transfer mechanism 5 has an open cabin inside that can accommodate the lifting device 2, and a support platform 51 is provided at the top of the battery transfer mechanism 5. The support platform 51 has a slot. The slot provided on the support platform 51 allows the grabbing rod 42 on the grabbing device 4 to extend. The purpose of the open cabin and the slot is to enable the grabbing device 4 to place the battery on the support platform 51 at the top of the battery transfer mechanism 5 and to enable the grabbing device 4 to take out the new battery on the support platform 51.

[0029] As a preferred embodiment, the length of the slider end of the lifting device 2 is longer than the width of the guide rail of the T-shaped guide rail 1 on which the battery transfer mechanism 5 is provided. The purpose of such a setting is to ensure that the grasping device 4 will not separate from the guide rail on which the grasping device 4 is located when cooperating with the battery transfer mechanism 5.

[0030] The working principle of the present utility model is as follows: when an electric vehicle stops at a designated location of a battery swap station and needs to swap batteries, the device first moves the lifting device 2 to the battery swap position through the T-shaped guide rail 1, and then uses the lifting device 2 to lift the grabbing device 4 to the bottom of the electric vehicle. When the driver stops at the battery swap station and the position is inaccurate, the motor is started to drive the two worms 33 to rotate. When the rotation directions of the two worms 33 are inconsistent, the rotation of the two worms 33 drives the worm wheel 32 to rotate, and the rotation of the worm wheel 32 drives the gear 38 to rotate. The rotation of the gear 38 drives the toothed frame 37 to move in the vertical direction of the rotation center of the worm 33 through the rack on the toothed frame 37, and the toothed frame 37 drives the grabbing device 4 to move synchronously. At the same time, changing the rotation direction of the two worms 33 can also change the rotation direction of the worm wheel 32, thereby changing the movement direction of the grabbing device 4. When the two worms 33 rotate in the same direction, the circumferential forces of the two worms 33 on the worm wheel 32 will cancel each other out, while the radial forces are in the same direction and the sum of the radial forces is greater than the friction force of the slider on the worm wheel 32 on the mounting plate 31. Therefore, the worm wheel 32 no longer rotates but moves along the vortex groove on the worm wheel 32. The worm wheel 32 also drives the movable guide rail 36 to make a linear motion along the linear guide rail 35, driving the movable guide rail 36 to simultaneously drive the toothed frame 37 to move synchronously, and then drive the grabbing device 4 on the toothed frame 37 to move synchronously. At the same time, changing the rotation direction of the two worms 33 can also change the moving direction of the worm wheel 32, and then change the movement direction of the grabbing device 4. According to the positional relationship between the electric vehicle and the grabbing device 4, the grabbing device 4 is adjusted in the above manner so that the grabbing device 4 is facing the position where the battery of the electric vehicle can be grabbed, and then the lifting device 2 is used to lift the grabbing device 4 to the inside of the battery of the electric vehicle so that the grabbing rod 42 is just inserted into the slot of the battery, and then the T-shaped guide rail 1 drives the grabbing device 4 to move toward the battery transfer mechanism. At this time, the battery is pulled out from the electric vehicle as the grabbing device 4 moves. After the battery is pulled out, it is transported to the battery transfer mechanism 5 along the grabbing device 4 and transported to the support platform 51 on the battery transfer mechanism 5. Then the lifting device 2 is started to make it descend, and then the battery remains above the support platform 51. The removed old battery is then transported away by the battery transfer mechanism 5, and the battery transfer mechanism 5 then transports the fully charged new battery to the intersection of the T-shaped guide rail 1, and then the grabbing device 4 takes the new battery away and installs it on the electric vehicle. The installation method of the new battery is similar to the disassembly method of the old battery and will not be elaborated here.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
