[0027] Combine Figures 1 to 6 As shown, the specific features of this modular mobile power supply are described in detail below:

[0028] A modular mobile power supply includes a mobile power supply body 1, a battery module 4 is arranged inside the mobile power supply body 1, a handle 2 is fixedly installed on the top of the mobile power supply body 1, a cover plate 3 is clamped on the outer wall of the mobile power supply body 1, an observation window 5 is provided on the cover plate 3, a guide groove 6 is provided on the mobile power supply body 1, a telescopic groove 7 is provided on the inner wall of the mobile power supply body 1, a through groove 8 is provided on the mobile power supply body 1, and a disassembly and assembly mechanism 9 is provided on the cover plate 3. By providing the disassembly and assembly mechanism 9, the cover plate 3 can be disassembled without the aid of tools, thereby facilitating the replacement of the battery module 4. A protective mechanism 10 is provided inside the telescopic groove 7. By providing the protective mechanism 10, a limit rod 96 can be prevented from sliding out of the mobile power supply body 1 through the guide groove 6, so that the limit rod 96 can stably limit the cover plate 3, thereby improving the stability of the cover plate 3.

[0029] The above-mentioned disassembly and assembly mechanism 9 includes a rotating shaft 91, a slide 92, a spring 93, an eccentric wheel 94, a knob 95, and a limiting rod 96; the rotating shaft 91 is rotatably connected to the inner wall of the cover plate 3, and the rotating shaft 91 passes through the cover plate 3, one end of the rotating shaft 91 is fixedly installed with the eccentric wheel 94, and the other end of the rotating shaft 91 is fixedly installed with the knob 95, the inner wall of the cover plate 3 is slidably connected with the slide 92, the inner wall of the slide 92 is fitted to the outer wall of the eccentric wheel 94, and the side wall of the slide 92 is fixedly installed with a limiting rod 96, and the rotating shaft 91 is rotated by turning the knob 95 to make the rotating shaft 91 drive the eccentric wheel 94 to rotate, and at this time the eccentric wheel 94 will squeeze the slide 92 upward to make the slide The frame 92 drives the limit rod 96 to move upward synchronously. When the limit rod 96 is flush with the guide groove 6, the cover 3 can be removed. The outer wall of the limit rod 96 is in contact with the inner wall of the mobile power supply body 1. The limit rod 96 is used in conjunction with the slide 92 to limit the cover 3, thereby completing the installation of the cover 3. A spring 93 is fixedly installed at the bottom of the slide 92. The end of the spring 93 away from the slide 92 is fixedly installed on the inner wall of the cover 3. The slide 92 can be pulled down and reset by the elasticity of the spring 93. At the same time, the slide 92 will drive the limit rod 96 to move downward synchronously, so that the limit rod 96 is staggered with the guide groove 6.

[0030] The above-mentioned protective mechanism 10 includes a triangular block 101, a ball rod 102, a magnet 103, and an iron rod 104; the triangular block 101 is slidably connected to the inner wall of the telescopic slot 7, and when the slide 92 drives the limit rod 96 to move downward, the limit rod 96 will squeeze the triangular block 101, so that the triangular block 101 slides toward the inside of the telescopic slot 7 and gradually moves away from the limit rod 96. A magnet 103 is fixedly installed on the top of the inner wall of the telescopic slot 7, and a ball rod 102 is slidably connected to the inner wall of the mobile power supply body 1. One end of the ball rod 102 extends to the inside of the guide slot 6. The ball rod 102 can be used to form a blocking effect in the inside of the guide slot 6 to prevent the limit rod 96 from moving out of the mobile power supply body 1 through the guide slot 6, so that the limit rod 9 6 stably limits the cover plate 3, the other end of the ball head rod 102 extends to the inside of the telescopic slot 7 and fits on the outer wall of the triangular block 101, and when the triangular block 101 gradually moves away from the limiting rod 96, it squeezes the ball head rod 102, causing the ball head rod 102 to slide upward and enter the inside of the guide slot 6, and an iron rod 104 is fixedly installed on the outer wall of the ball head rod 102, and the outer wall of the iron rod 104 fits on the inner wall of the through slot 8. When the ball head rod 102 slides upward, it will drive the iron rod 104 to move upward synchronously, so that the iron rod 104 can be adsorbed together with the magnet 103. At this time, the magnet 103 and the iron rod 104 can be used to limit the ball head rod 102, so that the ball head rod 102 can stay stably inside the guide slot 6.

[0031] Working principle: When the battery module 4 needs to be replaced, first rotate the shaft 91 through the knob 95, so that the shaft 91 drives the eccentric wheel 94 to rotate. At this time, the eccentric wheel 94 will squeeze the slide 92 upward, so that the slide 92 slides upward on the inner wall of the cover 3 and stretches the spring 93. At the same time, the slide 92 will drive the limit rod 96 to move upward synchronously. At this time, the observation window 5 can be used to observe whether the limit rod 96 is flush with the guide groove 6. When the limit rod 96 is flush with the guide groove 6, press the iron rod 104 downward to separate it from the magnet 103 and drive the ball head rod 102 to slide downward, so that the ball head rod 102 enters the interior of the telescopic slot 7 downward and disengages from the guide slot 6. At the same time, the ball head rod 102 will squeeze the triangle block 101, so that the triangle block 101 moves toward the extension The outside of the shrinkage groove 7 slides out. When the ball head rod 102 is completely out of the guide groove 6, the knob 95 can be used to pull the shaft 91, so that the shaft 91 pulls the cover plate 3, so that the cover plate 3 gradually moves away from the end of the mobile power supply body 1. At the same time, the limit rod 96 will fit the inner wall of the guide groove 6 and move synchronously. When the limit rod 96 is completely moved out of the guide groove 6, the cover plate 3 can be disassembled, so that the battery module 4 can be replaced. The cover plate 3 can be disassembled without the help of tools, which is convenient for the staff to replace the battery module 4. When the battery module 4 is replaced, the cover plate 3 needs to be installed with the mobile power supply body 1. First, the shaft 91 is rotated by the knob 95 to make the shaft 91 drive the eccentric wheel 94 to rotate. At this time, the eccentric wheel 94 The slide 92 will be squeezed upward, so that the slide 92 slides upward on the inner wall of the cover 3 and stretches the spring 93. At the same time, the slide 92 will drive the limit rod 96 to move upward synchronously. When the limit rod 96 moves to be flush with the guide groove 6, the limit rod 96 is aligned with the guide groove 6 and pushed into the inside of the mobile power supply body 1 until the outer wall of the cover 3 is in contact with the outer wall of the mobile power supply body 1. At this time, the knob 95 is released to stop the eccentric wheel 94 from squeezing the slide 92. At this time, the elasticity of the spring 93 can pull the slide 92 downward to reset. At the same time, the slide 92 will drive the limit rod 96 to move downward synchronously, so that the limit rod 96 is staggered with the guide groove 6. At this time, the limit rod 96 is used in conjunction with the slide 92 to limit the cover 3, thereby completing the cover The installation of the plate 3 makes the disassembly and installation of the cover plate 3 very convenient. When the slide 92 drives the limit rod 96 to move downward, the limit rod 96 will squeeze the triangular block 101, causing the triangular block 101 to slide toward the inside of the telescopic slot 7 and gradually away from the limit rod 96. At this time, the triangular block 101 will squeeze the ball head rod 102, causing the ball head rod 102 to slide upward and enter the inside of the guide slot 6. At the same time, the ball head rod 102 will drive the iron rod 104 to move upward synchronously, so that the iron rod 104 and the magnet 103 can be adsorbed together. At this time, the magnet 103 and the iron rod 104 can be used to limit the ball head rod 102, so that the ball head rod 102 can stay stably in the inside of the guide slot 6. When the knob 95 is accidentally touched, the shaft 91 and the eccentric wheel 94 are driven to rotate.When the slide 92 drives the limiting rod 96 to move to the guide groove 6, the ball rod 102 can form a blocking effect inside the guide groove 6, preventing the limiting rod 96 from moving out of the mobile power supply body 1 through the guide groove 6. The limiting rod 96 stably limits the cover plate 3, preventing the cover plate 3 from falling off due to accidental contact of the knob 95, thereby improving the stability of the cover plate 3.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
