Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5This utility model provides a technical solution:
[0020] A multi-functional electric tricycle with good cargo carrying capacity and lifting function includes a frame 1 and a cargo box 6. A sunken frame 2 is installed on the frame 1 below the cargo box 6. A partition 3 is installed inside the sunken frame 2. A mobile power structure 4 for movement is installed below the partition 3. The sunken frame 2 above the partition 3 is connected to the bottom of the cargo box 6 through a lifting frame 5, thereby separating the two systems and facilitating later maintenance. An auxiliary bracket 8 is detachably connected to the top of the cargo box 6, which can provide support when raised and ensure stability. A protective structure 7 is provided on the side of the sunken frame 2 to prevent the lifting frame 5 from moving accidentally. This can lock the cargo box 6 when it is not raised, thereby preventing the cargo box 6 from being raised accidentally. After the cargo box 6 is raised, the power to the mobile power structure 4 is cut off by opening the protective structure 7, thereby preventing the mobile power structure 4 from working unexpectedly and improving safety.
[0021] The bottom of the mobile power structure 4 is equipped with a gearbox 41. Both sides of the gearbox 41 are equipped with main shafts 42 that extend out of the sunken frame 2 and are connected to rear wheels 44. The inner wall of the sunken frame 2 is equipped with a power motor 43 that drives the gearbox 41 to rotate. The operation of the power motor 43 is controlled by the electrical control box 12, so that the frame 1 can move.
[0022] The bottom side of the lifting frame 5 is installed inside the sunken frame 2 via a positioning shaft 51. A guide frame 52 is installed on the other side of the sunken frame 2. A slider 53 is slidably installed inside the guide frame 52. A proximity switch 54 is installed on the end face of the guide frame 52 near the positioning shaft 51. The slider 53 is connected to the other side of the bottom of the lifting frame 5 via a rotating shaft. An upper frame 56 is installed at the top of the lifting frame 5. The lifting frame 5 inside the upper frame 56 is fixed in the same way as the lifting frame 5 inside the sunken frame 2. An electric push rod 55 for adjusting the height is installed inside the lifting frame 5. When lifting is required, the operation of the electric push rod 55 is controlled by the control box 12, which causes the slider 53 to move inside the guide frame 52. When the slider 53 moves to the proximity switch 54, it indicates that the lifting frame 5 has reached its limit position. At this time, the control box 12 receives a signal and controls the electric push rod 55 to stop extending, ensuring the safety of operation.
[0023] The protective structure 7 includes mounting block 1 71 and mounting block 2 72 installed at the front and rear ends inside the recessed frame 2. A sleeve 75 is provided between mounting block 2 72 and the recessed frame 2. A sliding rod 73 is slidably installed inside the sleeve 75. One end of the sliding rod 73 passes through and extends to the outside of the recessed frame 2 and is connected to a handle 74. The other end of the sliding rod 73 passes through and extends to the outside of mounting block 2 72. A proximity switch 2 7 is installed inside the recessed frame 2 on the side of mounting block 2 72. 10. An L-shaped groove 76 is provided on the sleeve 75. A protrusion 77 that can slide in the L-shaped groove 76 is provided on the side of the slide rod 73. A protrusion 78 is installed on the slide rod 73 between mounting block 1 71 and mounting block 2 72. A spring 79 is sleeved on the outside of the slide rod 73 between protrusion 78 and mounting block 1 71. A mounting block 711 is installed at the bottom of the truck bed 6 between mounting block 2 72 and proximity switch 2 710. A protrusion 77 is provided on the surface of mounting block 3 711 corresponding to the slide rod 73. The device has a slot 712, which allows the sliding rod 73 to be locked inside the slot 712 when the truck bed 6 is not raised, thus preventing the truck bed 6 from being raised accidentally. At this time, the end of the sliding rod 73 is in contact with the second proximity switch 710. The electrical control box 12 provides power to the moving power structure 4, which facilitates the overall movement operation. Conversely, when the truck bed 6 needs to be raised, pulling the sliding rod 73 outward causes the protrusion 77 to be locked in the short groove of the L-shaped groove 76. At this time, the spring is compressed, and the sliding rod 73 moves away from the second proximity switch 710. At this time, the electrical control box 12 cuts off the power supplied to the moving power structure 4, thus preventing the overall movement from being moved accidentally. After the truck bed 6 is completely lowered, the protrusion 77 is rotated out of the short groove in the L-shaped groove 76. Under the action of the spring 79, the sliding rod 73 is reset, so that the sliding rod 73 is in contact with the second proximity switch 710. At the same time, the sliding rod 73 also passes through the inside of the slot 712, thus achieving the fixed operation.
[0024] The frame 1 is equipped with a seat 11, and an electrical control box 12 is installed inside the seat 11. A front panel 61 is installed in the cargo box 6 near the seat 11. Side panels 62 are rotatably connected to both sides of the cargo box 6. A rear panel 63 is rotatably connected to the cargo box 6 away from the seat 11. A connecting sleeve 64 is installed at the top of the side panel 62. A side auxiliary baffle 65 is installed above the side panel 62. The side auxiliary baffle 65 is connected to the connecting sleeve 64 via a connecting pin 66. A rear auxiliary baffle 69 is connected to the side of the side auxiliary baffle 65 above the rear panel 63 via a hinge 68. The side of the side auxiliary baffle 65 is connected to the side of the front panel 61 via a tricycle cargo box latch 67. Thus, the side auxiliary baffle 65 and the rear auxiliary baffle 69 can be added according to the needs of use, so as to carry more goods and meet people's needs for goods transportation in daily life.
[0025] The auxiliary support 8 includes crossbars 82 distributed around the frame 1. A mounting groove 81 is provided on the sunken frame 2 at the position corresponding to the crossbars 82. A screw hole is provided on the side of the mounting groove 81, and a locking pin is threaded into the screw hole. An outer tube 83 is installed at the bottom of the crossbars 82. An inner tube 84 is slidably installed inside the outer tube 83. An adjusting screw 85 is connected to the inside of the inner tube 84 via a screw seat. The top of the adjusting screw 85 passes through and extends to the outside of the outer tube 83. A pad 86 is installed at the bottom of the inner tube 84. This allows the crossbars 82 to be pulled outwards as needed when the truck bed 6 is raised, then fixed by the locking pin. Adjusting the adjusting screw 85 allows the inner tube 84 to extend, ultimately causing the pad 86 to contact the truck bed, thus providing auxiliary support and improving bottom stability during operation.
[0026] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
