[0003] However, the existing detachable battery packs for electric tricycles are relatively complicated to disassemble, which reduces the speed of disassembly and thus reduces the efficiency of battery pack disassembly, affecting the efficiency of battery pack testing. Utility Model Content
[0004] The purpose of this utility model is to provide a detachable battery pack for electric tricycles. By setting a fixing mechanism, it solves the problem that the existing detachable battery packs for electric tricycles are complicated to disassemble during use, which reduces the speed of battery pack disassembly and thus reduces the efficiency of battery pack disassembly, affecting the efficiency of battery pack testing.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a detachable battery pack for an electric tricycle, including an electric tricycle and a rectangular box fixedly connected to the electric tricycle. The rectangular box has a battery pack fixing area and a storage area. The electric tricycle and the rectangular box are provided with a fixing mechanism and an auxiliary mechanism. The fixing mechanism is located in the battery pack fixing area inside the rectangular box, and the auxiliary mechanism is located in the storage area inside the rectangular box.
[0007] The top of the rectangular box is hinged with a partition. The fixing mechanism includes two trapezoidal slides 1 opened inside the rectangular box and a sliding connecting plate between the two trapezoidal slides 1. A bidirectional hinge block is fixedly connected to the bottom inner wall of the rectangular box. The auxiliary mechanism includes a limiting block fixedly connected to the bottom of the partition and a groove opened on the limiting block. A trapezoidal slide 3 is opened on the left inner wall of the rectangular box.
[0008] Furthermore, the bidirectional hinge block is hinged with two hinge rods, the bottom of the slide plate has two trapezoidal grooves, the inner walls of the two trapezoidal grooves are slidably connected to the hinge block, the two hinge blocks are respectively hinged to the two hinge rods, the two hinge blocks are hinged with two hinge rods, and the slide plate has a limit groove.
[0009] Furthermore, the inner wall of the limiting groove is slidably connected to two sliders, and the two sliders are hinged to several hinge rods. Several spring telescopic rods are fixedly connected between the bottom inner wall of the rectangular box and the bottom of the slide plate.
[0010] Furthermore, two fixing plates are fixedly connected to the top of each of the two sliders, and anti-slip pads are fixedly connected to the side of each of the two fixing plates that are close to each other. Several spring telescopic rods are fixedly connected to the bottom of the partition, and protective pads are fixedly connected to the bottom of each of the several spring telescopic rods.
[0011] Furthermore, a rack is slidably connected to the inner wall of the trapezoidal slide groove three, and an arc-shaped block is fixedly connected to the front side of the rack. The arc-shaped block is adapted to the limiting block. A spring is provided inside the trapezoidal slide groove three. The front side of the spring is fixedly connected to the rack, and the rear side of the spring is fixedly connected to the rear inner wall of the trapezoidal slide groove three.
[0012] Furthermore, a rotating shaft is rotatably connected to the left inner wall of the rectangular box, the left side of the rotating shaft extends to the outside of the rectangular box, a gear is fixedly connected to the outer wall of the rotating shaft, the gear meshes with a rack, and a handle is fixedly connected to the outer wall of the rotating shaft.
[0013] This utility model has the following beneficial effects:
[0014] 1. By setting up a fixing mechanism, the battery pack is placed on the slide, and then the partition is closed. At this time, the partition, through several spring-loaded telescopic rods, drives several protective pads to compress the battery pack. The battery pack then pushes the slide downwards within two trapezoidal slides. The parallel design of the two trapezoidal slides ensures smooth movement of the slide. The slide compresses the spring-loaded telescopic rods, causing them to deform and generate elasticity. As the slide moves downwards, two hinge blocks compress two hinge rods. The two hinge rods rotate around the bidirectional hinge blocks as fulcrums, increasing the angle between them. The two hinge rods then drive the two hinge blocks to slide within the two trapezoidal slides and move away from each other. The two hinge blocks then pull the corresponding two hinge rods to move. At this point, several hinges... The connecting rods rotate around the connected sliders as fulcrums, causing the angle between several connecting rods to decrease. This causes the two sliders to slide and move closer to each other within the limiting groove. At this time, the two sliders move the two anti-slip pads closer to each other through the two fixed plates, thereby clamping and fixing the battery pack. When the battery pack needs to be disassembled, the partition is opened, causing several spring telescopic rods and protective pads to move away from the battery pack. At this time, under the elastic force of several spring telescopic rods, the slide plate is pushed upward. Through the reverse operation process, the two fixed plates move the two anti-slip pads away from the battery pack, thereby releasing the battery pack from the fixation. This makes the operation process highly automated, greatly improving disassembly efficiency, shortening disassembly time, and improving maintenance efficiency. It also avoids hard parts directly rubbing against the battery shell, protecting the battery pack safety.
[0015] 2. By setting an auxiliary mechanism, when the partition is closed, the partition drives the limiting block to move downwards. At this time, the limiting block presses against the arc-shaped block through the arc surface, causing the arc-shaped block to move backwards. The arc-shaped block then pushes the rack to slide within the trapezoidal groove and compresses the spring, causing the spring to deform and generate elastic force. When the groove on the limiting block aligns with the arc-shaped block, the spring force pushes the arc-shaped block into the groove within the limiting block via the rack. The cooperation between the right-angled surface of the limiting block's groove and the right-angled surface of the arc-shaped block fixes the partition. To open the partition... When opening the separator, turning the handle counterclockwise rotates the shaft, which in turn drives the gear to rotate. Under the meshing action of the gear and rack, the counterclockwise rotation of the gear drives the arc-shaped block to move backward through the rack, causing the arc-shaped block to leave the groove of the limiting block, thereby releasing the restriction on the separator and opening it to remove the battery pack. This prevents external forces such as vibration and bumps during vehicle operation from causing the separator to unlock itself due to shaking, ensuring the safety of the battery pack in a fixed state and preventing accidental unlocking and detachment of the battery pack due to accidental operation such as accidentally touching the separator, thus improving the safety of use.

Several spring telescopic rods 2113 are fixedly connected to the bottom of the partition 112. Protective pads 2114 are fixedly connected to the bottom of the several spring telescopic rods 2113. By setting the fixing mechanism 2, the operation process is highly automated, which greatly improves the disassembly efficiency, shortens the disassembly time, improves the maintenance efficiency, and avoids the direct friction of hard parts against the battery shell, thus protecting the safety of the battery pack.
[0028] The auxiliary mechanism 3 includes a limiting block 311 fixedly connected to the bottom of the partition 112. A trapezoidal slide groove 312 is provided on the left inner wall of the rectangular box 111. A rack 313 is slidably connected to the inner wall of the trapezoidal slide groove 312. An arc-shaped block 314 is fixedly connected to the front side of the rack 313, and the arc-shaped block 314 is adapted to the limiting block 311. A spring 315 is provided inside the trapezoidal slide groove 312.

By setting the auxiliary mechanism 3, external forces such as vibration and bumps during vehicle operation are prevented from causing the partition 112 to unlock itself due to shaking. This ensures the safety of the battery pack in a fixed state and prevents accidental unlocking and detachment of the battery pack due to accidental operation such as accidentally touching the partition, thereby improving the safety of use.
[0029] A specific application of this embodiment is as follows: In use, the battery pack is placed on the slide plate 212, and then the partition 112 is closed. At this time, the partition 112, through several spring telescopic rods 2113, drives several protective pads 2114 to compress the battery pack. The battery pack pushes the slide plate 212 to slide downwards within two trapezoidal slide grooves 211. The parallel design of the two trapezoidal slide grooves 211 ensures that the slide plate 212 moves smoothly. At this time, the slide plate 212 compresses several spring telescopic rods 2110, causing deformation and generating elasticity. When the slide plate 212 moves downwards, it compresses two hinge rods 214 through two hinge blocks 216. At this time, the two hinge rods 214 rotate around the bidirectional hinge block 213 as a fulcrum, causing the two... As the angle between the two hinge rods 214 increases, the two hinge rods 214 respectively drive the two hinge blocks 216 to slide and move away from each other within the two trapezoidal slide grooves 215. At this time, the two hinge blocks 216 respectively pull the corresponding two hinge rods 217 to move. The several hinge rods 217 then rotate around the connected sliders 219 as fulcrums, causing the angle between the hinge rods 217 to decrease. This causes the two sliders 219 to slide and move closer to each other within the limiting slide groove 218. The two sliders 219 then drive the two anti-slip pads 2112 to move closer together via the two fixing plates 2111, thereby clamping and fixing the battery pack. When the battery pack needs to be disassembled, opening the partition 112 activates several spring telescopic rods 217. 2113 and protective pad 2114 move away from the battery pack. At this time, under the elastic force of several spring telescopic rods 2110, the slide plate 212 is pushed upward. Through the reverse operation process, the two fixed plates 2111 respectively drive the two anti-slip pads 2112 away from the battery pack, thereby releasing the fixation of the battery pack. When the partition 112 is closed, the partition 112 drives the limiting block 311 to move downward. At this time, the limiting block 311 presses the arc surface of the arc block 314, causing the arc block 314 to move backward. At this time, the arc block 314 pushes the rack 313 to slide in the trapezoidal slide groove 312 and presses the spring 315, causing the spring 315 to deform and generate elastic force. When the groove on the limiting block 311 When corresponding to the arc-shaped block 314, under the action of the spring force of the spring 315, the arc-shaped block 314 is pushed by the rack 313 into the groove of the limiting block 311. With the cooperation of the right angle surface of the groove of the limiting block 311 and the right angle surface of the arc-shaped block 314, the partition 112 is fixed. When the partition 112 needs to be opened, the handle 318 is turned counterclockwise to drive the rotating shaft 316 to rotate. At this time, the rotating shaft 316 drives the gear 317 to rotate. Under the action of the meshing of the gear 317 and the rack 313, the gear 317 rotates counterclockwise and drives the arc-shaped block 314 to move backward through the rack 313, causing the arc-shaped block 314 to leave the groove of the limiting block 311, thereby releasing the restriction on the partition 112, thus opening the partition 112 and taking out the battery pack.
