[0027] See Figures 1 to 6 This application provides an intelligent electric suitcase, including a rideable suitcase body 10, a handle 20 installed on the suitcase body 10, a rear wheel 101 installed on the bottom rear side of the suitcase body 10, and a front wheel 201 installed on the bottom of the handle 20. The front wheel 201 is a hub motor wheel used to drive the suitcase body 10 to move. The handle lever 20 includes a fixed rod 202 and a lifting rod 203. The lifting rod 203 is slidably mounted on the upper part of the fixed rod 202 and can slide along the length of the fixed rod 202. A handle 204 is installed on the upper part of the lifting rod 203. A drive motor 205 is provided inside the fixed rod 202. A lead screw 206 is provided at the output end of the drive motor 205. The lead screw 206 is threadedly connected to the lifting rod 203. When the drive motor 205 is started, its output end drives the lead screw 206 to rotate. Since the drive motor 205 is fixed, when the lead screw 206 rotates, the lifting rod 203, which is threadedly connected to the lead screw 206, moves up and down around the thread direction, thereby realizing the electric lifting of the handle lever 20.

[0028] See Figures 6 to 8The lead screw 206 has an external thread on its outer periphery, and the bottom of the lifting rod 203 has a rotating connecting block 207. The rotating connecting block 207 is fixedly connected to the lifting rod 203. The rotating connecting block 207 has an internal thread that matches the external thread. The lead screw 206 is inserted into the rotating connecting block 207 to achieve a threaded connection with the lifting rod 203.

[0029] See Figure 5 , Figure 6 and Figure 9 The fixed rod 202 has a motor mounting seat 208 inside, and the drive motor 205 is fixedly installed in the motor mounting seat 208. The inner side wall of the fixed rod 202 has a limiting rib 209, and the outer side wall of the lifting rod 203 has a limiting groove 210 that matches the limiting rib 209. The lifting rod 203 slides relative to the fixed rod 202 by inserting the limiting rib 209 into the limiting groove 210. The cooperation between the limiting rib 209 and the limiting groove 210 provides sliding guidance for the sliding of the lifting rod 203 and provides steering limit for the lifting rod 203 and the fixed rod 202, so that when the lifting rod 203 turns left or right, it can synchronously drive the fixed rod 202 to turn left or right, thereby driving the front wheel 201 to turn.

[0030] See Figure 7 and Figure 9 The lifting rod 203 has a partition 211 inside, which divides the inside of the lifting rod 203 into a first cavity 212 and a second cavity 213. The lead screw 206 is inserted into the first cavity 212 and threadedly connected to the lifting rod 203. The second cavity 213 is equipped with a signal connection line 214. By setting the partition 211, the lead screw 206 and the signal connection line 214 can be separated, so as to avoid interference or entanglement between the lead screw 206 and the signal connection line 214 during the rotation of the lead screw 206.

[0031] See Figure 2 , Figures 10 to 12 The intelligent electric suitcase provided in this application also includes a battery 102, a controller 103, a slide rail 104 fixed inside the suitcase body, a telescopic rod 105 mounted on the slide rail 104 and protruding outside the suitcase body 10 that can slide along the slide rail 104, and an electric push rod 106 for driving the telescopic rod 105 to slide.

A battery slot 107 is provided at the rear of the suitcase body 10, and the battery 102 is detachably installed in the battery slot 107.

[0032] The lifting rod 203 has a handle 204 on its upper part. The handle 204 has a control component 215 for controlling the forward or backward movement of the hub motor wheels. The control component 215 includes a speed control knob 216 and a brake knob 217, both of which can rotate circumferentially. Both the speed control knob 216 and the brake knob 217 have a force-applying element that allows for thumb pressing or flicking. Both the speed control knob 216 and the brake knob 217 are connected to the controller 103 via a signal connection line 214. When the user operates the control component 215, pressing the corresponding force-applying element with their thumb rotates the speed control knob 216 or the brake knob 217 circumferentially, thus adjusting the speed and applying the electronic brake to the electric suitcase. The speed controller of the speed control knob 216 is a potentiometer or a Hall sensor.

[0033] The front of the housing 10 has an opening 108, on which a front baffle 109 is installed. The upper part of the front baffle 109 has an insertion hole 110 for the telescopic rod 105 to pass through, and the lower part of the front baffle 109 has a groove 111 that matches the front wheel 201. When the telescopic rod 105 is in the retracted state, the front wheel 201 is located in the groove 111. A slide rail 104 is located at the insertion hole 110 and is integrally formed with the front baffle 109. When the telescopic rod 105 passes through the insertion hole 110, it is simultaneously inserted into the slide rail 104. One end of the electric push rod 106 is connected and fixed to the interior of the housing 10, and the other end is connected and fixed to the telescopic rod 105, providing power for the sliding of the telescopic rod 105.

[0034] Both sides of the front wheel 201 are equipped with pedals 218, which can provide foot support for the user while riding to improve the user's riding comfort; the rear of the box 10 is equipped with a rear pull rod 219, which allows the user to choose between riding the suitcase and pushing and pulling the suitcase. When the user does not want to ride, the rear pull rod 219 can be pulled out to push and pull the suitcase.
