DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 8As shown, a novel electric energy storage device comprises a main box body 1, a sub-box body 2, a lifting mechanism 3, a guide mechanism 4, and a ventilation groove 5. The top of the main box body 1 is penetrated, and the inner cavity accommodates the sub-box body 2. The lifting mechanism 3 is installed between the main box body 1 and the sub-box body 2. The left and right parts of the main box body 1 are respectively installed with a guide mechanism 4, and the left and right parts are respectively penetrated with a ventilation groove 5. The lower left and right parts of the sub-box body 2 are respectively hinged with a lower support plate 6, and the upper parts of the two lower support plates 6 are respectively hinged with an upper support plate 7. The top of the sub-box body 2 is penetrated, and the top end is closed by a locking mechanism 8. The middle support plate 9, the two lower support plates 6 can be respectively fitted with the left and right ends of the auxiliary box 2 and are in a vertical state, the two upper support plates 7 can be respectively fitted with the top of the middle support plate 9 and are in a horizontal state, and when the two upper support plates 7 are in a horizontal state, they can cover the top of the main box 1 and completely enclose the auxiliary box 2 in the main box 1, the lower support plate 6, the upper support plate 7 and the middle support plate 9 are jointly installed with a photovoltaic power generation component 10, and a battery 11 and a controller 12 are fixed in the auxiliary box 2, and the photovoltaic power generation component 10 is electrically connected to the battery 11 and the controller 12.

[0022] When in use, the electric energy storage device is installed at the pedal position of the electric bicycle, and the upper support plate 7 is used as a pedal. During normal riding, the upper support plate 7 covers the main box 1, the sub-box 2 is contained in the main box 1, the battery 11 supplies power to the electric bicycle, and the driver's feet are placed on the top of the upper support plate 7. When there is a lot of water on the road, the sub-box 2 can be moved upward by controlling the action of the lifting mechanism 3. When it reaches a certain position, the upper support plate 7 is manually pushed so that the upper support plate 7 is separated from the middle support plate 9, and the bottom end of the upper support plate 7 is in contact with the adjacent ends of the two lower support plates 6. At this time, the opposite ends of the two lower support plates 6 are in contact with the top of the main box 1 and are in a horizontal state, and the upper support plate 7 also remains horizontal. At this time, the driver's feet can be placed on the top of the upper support plate 7 corresponding to the lower support plate 6, which can stably support the driver's feet, and the height increase of the battery 11 in the sub-box 2 reduces the risk of circuit failure caused by water ingress. When the bicycle needs to be parked for a long time and there is sufficient sunlight outside (such as more than one hour), the photovoltaic power generation assembly 10 is used to generate electricity to charge the battery 11. By manually unfolding the lower support plate 6 and the upper support plate 7, the overall width of the electric bicycle can be increased, thereby increasing the parking interval between vehicles and facilitating the entry and exit of vehicles. When it is necessary to restore the normal state, the auxiliary box 2 can be moved down and accommodated in the main box 1 by controlling the lifting mechanism 3, and the upper support plate 7 and the lower support plate 6 can be reset under the guidance of the guide mechanism 4.

[0023] The photovoltaic power generation assembly 10 includes a lower photovoltaic panel 13, an upper photovoltaic panel 14, and a middle photovoltaic panel 15. The lower photovoltaic panels 13 are respectively embedded and fixed at adjacent ends of the two lower support plates 6, the upper photovoltaic panels 14 are respectively embedded and fixed at the bottom ends of the two upper support plates 7, and the middle photovoltaic panels 15 are respectively embedded and fixed at the top ends of the two middle support plates 9. The lower photovoltaic panels 13, the upper photovoltaic panels 14 and the middle photovoltaic panels 15 are respectively electrically connected to the controller 12.

[0024] Furthermore, when the bicycle needs to be parked for a long time and there is sufficient sunlight outside (such as more than one hour), the upper support plate 7 is manually flipped outward based on the previous step. At this time, the bottom end of the upper support plate 7 will flip under the action of gravity and then fit with the bottom end of the lower support plate 6 in a horizontal state. At this time, the lighting surfaces of the lower photovoltaic panel 13, the upper photovoltaic panel 14 and the middle photovoltaic panel 15 are all upward. Then the electric bicycle is moved to a well-lit position, and the lower photovoltaic panel 13, the upper photovoltaic panel 14 and the middle photovoltaic panel 15 can be used to generate electricity, and then the battery 11 is charged after rectification, voltage transformation and other processing by the controller 12.

[0025] The lifting mechanism 3 includes a support seat 16, a support arm 17, a support frame 18, a bidirectional screw rod 19, a support block 20, a polished rod 21, and a servo motor 22. A group of support seats 16 are fixed to the front and rear parts of the bottom end of the inner wall of the main box 1, and the two corresponding support seats 16 on the left and right are a group. The two groups of support seats 16 are respectively hinged with a group of support arms 17 front and back, and the two corresponding support arms 17 on the left and right are a group. A horizontal support frame 18 is fixed to the bottom end of the auxiliary box 2. The support frame 18 is rotatably connected to a horizontal bidirectional screw rod 19 in the front and rear directions. The rotation directions of the external threads of the front and rear parts of the bidirectional screw rod 19 are opposite, and the front and rear parts of the bidirectional screw rod 19 are each threadedly connected There are horizontal support blocks 20, and the top ends of the two support blocks 20 are flush with the bottom ends of the auxiliary box body 2 respectively. Horizontal light rods 21 are fixed to the left and right ends of the two support blocks 20 respectively. The light rods 21 at the left and right ends of the support blocks 20 are respectively slidably connected to the left and right parts of the support frame 18, and each light rod 21 is hinged to the upper part of each support arm 17 respectively. When the auxiliary box body 2 is accommodated in the main box body 1, the bottom end of the support frame 18 can be in contact with the top end of the support seat 16. A vertical servo motor 22 is fixed to the bottom of the auxiliary box body 2. The rotating shaft of the servo motor 22 is meshed with the bidirectional screw rod 19 through a bevel gear for transmission, and the servo motor 22 is electrically connected to the controller 12.

[0026] The controller 12 controls the servo motor 22 to rotate forward and reverse, which can make the bidirectional screw 19 rotate forward and reverse under the drive of the bevel gear, so that the two support blocks 20 can move closer to and away from each other, and then the light rod 21 and the support arm 17 can be used to drive the support frame 18 and the auxiliary box body 2 to move up and down.

[0027] The guide mechanism 4 includes a mounting seat 24, a roller 25, a guide block 26, and a receiving groove 27. Two mounting seats 24 are fixed at the left and right ends of the inner wall of the main box body 1. Each of the mounting seats 24 is connected with a horizontal roller 25 that rotates in the front and rear directions. A group of guide blocks 26 are fixed to the left and right parts of the top of the main box body 1. Two front and rear corresponding guide blocks 26 form a group. The two groups of guide blocks 26 are pointed tops that gather toward the upper middle part of the main box body 1. The front and rear parts of the bottom ends of the two upper support plates 7 are each provided with a receiving groove 27. When the upper support plates 7 are covered on the top of the main box body 1, the guide blocks 26 are large enough to be received by the receiving groove 27.

[0028] When the auxiliary box 2 descends and only the upper support plate 7 is in the unfolded state, the upper support plate 7 is first flipped and unfolded. When the auxiliary box 2 descends and both the upper support plate 7 and the lower support plate 6 are in the unfolded state, as the auxiliary box 2 descends, the lower support plate 6 is squeezed by the rollers 25 and gradually fits toward the left and right ends of the auxiliary box 2, and moves downward with the auxiliary box 2. At this time, the upper support plate 7 also moves downward, and when it contacts the guide block 26, it can be guided to flip in the opposite direction, that is, restore the fit between the upper support plate 7 and the middle support plate 9. After the auxiliary box 2 further descends, the guide block 26 is accommodated in the accommodation groove 27, and the upper support plate 7 also resumes covering the main box 1.

[0029] There are two middle support plates 9, and the two middle support plates 9 are respectively connected to the auxiliary box body 2 for front and rear sliding. The locking mechanism 8 includes a socket 28, a guide groove 29, a slider 30, a plug rod 31, a push rod 32, a compression spring 33, a buckle groove 34, a combined password lock 35, and a combined slot 36. The adjacent parts of the two middle support plates 9 are respectively penetrated by horizontal sockets 28 in the left and right directions. The left and right parts of the top of the main box body 1 are respectively provided with guide grooves 29. The two guide grooves 29 are respectively connected to the sliders 30 for left and right sliding. The front and rear parts of the opposite ends of the two sliders 30 are respectively fixed with horizontal plug rods 31. The adjacent ends of the two sliders 30 are respectively fixed with horizontal push rods 32. The adjacent parts of the two sliders 30 are respectively fixed with horizontal compression springs 33 together with the guide grooves where they are located. Under the action of the elastic repulsive force of the compression spring 33, they have a tendency to slide away from each other. The upper parts of the two sliders 30 are respectively provided with buckle grooves 34, and each of the plug rods 31 can be respectively plugged into and disengaged from the plug hole 28. A combined password lock 35 is installed in the upper middle part of the sub-box 2. The combined password lock 35 is provided with a combined slot 36. The combined password lock 35 controls whether the combined slot 36 is connected. When the combined slots 36 are connected to each other, the two push rods 32 can be inserted into the combined slots 36 so that the two sliders 30 can be close to each other to the maximum extent and the plug-in connection between the plug rod 31 and the plug hole 28 can be released. When the combined slots 36 are not connected to each other, the two push rods 32 cannot be inserted into the combined slots 36, so that the two sliders 30 cannot be close to each other to the maximum extent and the plug-in connection between the plug rod 31 and the plug hole 28 cannot be released.

[0030] Furthermore, in order to improve the anti-theft performance of the battery 11, a combination password lock 35 is set. When the password of the combination password lock 35 is correct, the combination slot 36 is connected and corresponds to the push rod 32, and the push rod 32 can be inserted into the combination slot 36. At this time, the two sliders 30 are manually moved to make the two close to each other, so that the connection between the plug rod 31 and the socket 28 can be released. Then the center support plate 9 can be slid to facilitate the handling of the battery 11. If the password is incorrect, the combination slot 36 is not connected, and the plug rod 31 cannot be inserted into the combination slot 36, that is, the plug rod 31 and the socket 28 cannot be normally released, thus achieving the purpose of anti-theft.

[0031] The combined password lock 35 includes a number one password disk 37, a number two password disk 38, a center disk 39, an indicator groove 40, an etching groove 41, a sponge block 42, an outer pin 43, a number one slot 44, a number two slot 45, a receiving hole 46, a sponge tube 47, an inner pin 48, a pin hole 49, and a knurling 50. The upper middle part of the auxiliary box 2 is rotatably connected with a vertical number one password disk 37, the number one password disk 37 is coaxially rotatably connected with the number two password disk 38, the number two password disk 38 is coaxially rotatably connected outside the center disk 39, the center disk 39 is fixed to the auxiliary box 2, and the center disk The left and right parts of the top of the No. 1 code disk 39 are respectively provided with an indicating groove 40. The top of the No. 1 code disk 37 and the top of the No. 2 code disk 38 are respectively provided with the same number of etching grooves 41 at equal angles in the circumference. Different etching grooves 41 are used to etch different numbers or letters. A sponge block 42 is fixed at the bottom of the No. 1 code disk 37. A plurality of horizontal external pins 43 are inserted into the sponge block 42. A No. 1 slot 44 is penetrated through the bottom of the No. 1 code disk 37 on the left and right sides. Each of the external pins 43 and the No. 1 slot 44 is arranged at equal angles in the centripetal circle compared to the No. 1 code disk 37. Each of the external pins 43 and the No. 1 slot 44 is arranged at equal angles in the centripetal circle compared to the No. 1 code disk 37. The No. 1 slot 44 corresponds to each etched groove 41 at the top of the No. 1 code disk 37. The No. 2 slot 45 runs through the bottom of the No. 2 code disk 38. The No. 2 code disk 38 runs through the bottom of a plurality of horizontal receiving holes 46. A horizontal sponge tube 47 is fixed in each of the receiving holes 46. A horizontal inner pin 48 is inserted in each of the sponge tubes 47. Each of the inner pins 48 and the No. 2 slot 44 is arranged at an equal angle to the centripetal circumference of the No. 2 code disk 38. Each of the inner pins 48 and the No. 2 slot 45 is arranged at the top of the No. 2 code disk 38. Each etching groove 41 corresponds to each other one by one up and down, and a plurality of horizontal pin holes 49 are opened at equal angles on the bottom circumference of the center disk 39. Each of the outer pins 43 and the inner pins 48 can correspond to the pin holes 49 in the radial direction. The outer walls of the outer pins 43 and the outer walls of the inner pins 48 are respectively provided with knurling 50. The outer pins 43 can push the inner pins 48 to be inserted into the pin holes 49 under the action of external force and keep the plug-in state under the friction effect of the knurling 50. The push rod 32 can push the inner pins 48 to be inserted into the socket 28 under the action of external force and keep the plug-in state under the friction effect of the knurling 50.

[0032] Furthermore, in order to improve the anti-theft effect, the combination lock 35 can only be unlocked after the correct password is entered and then normal operation is performed, and it is difficult to unlock by trial and error. When the password is correct, the correct password (composed of numbers or letters etched in the etching groove 41) corresponds to the indicator groove 40, and the No. 1 slot 44 is connected with the No. 2 slot 45 to form a connected combination slot 36, and then the insertion rod 31 can be inserted into the combination slot 36 for normal locking and unlocking. When the password is unknown and the trial and error unlocking is desired, if the password is wrong, the No. 1 slot 44 is not connected with the No. 2 slot 45, and the combination slot 36 is not connected. When the two sliders 30 are pushed against each other, the push rod 32 will push the outer pin 43 to move toward the center disk 39, and the outer pin 43 will indirectly push the inner pin 48 to move toward the center disk 39; or the push rod directly pushes the inner pin 48 to move toward the center disk 39. The former will cause the outer pin 43 to be inserted into the receiving hole 46, and can further cause the inner pin 48 to be inserted into the pin hole 49, thereby causing the number one code disk 37 and the number two code disk 38 to no longer rotate relative to the center disk 39, that is, it is impossible to continue trial and error, while the latter directly causes the inner pin 48 to be inserted into the pin hole 49, thereby causing the number two code disk 38 to no longer rotate relative to the center disk 39, that is, it is impossible to continue trial and error, thereby reducing the chance of trial and error unlocking, and indirectly reducing the desire of thieves to unlock and steal.

[0033] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
