Description

Technical Field

[0001] This utility model relates to electric suitcases, and more particularly to an electric suitcase with an electric retractable foot pedal. Background Technology

[0002] Most existing electric luggage compartments have fixed or manual foot pedals;

[0003] Fixed foot pedals usually extend a certain distance out of the housing, which may cause them to bump into pedestrians or other objects during use;

[0004] Manual operation is generally divided into two types: manual disassembly and manual folding. Both of these require users to disassemble and assemble themselves, which is inconvenient, time-consuming, and laborious, resulting in a poor user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the problems that the foot pedals on existing electric suitcases are mostly fixed or manual, which are inconvenient to use, time-consuming and laborious, and have a poor user experience, an electric suitcase with an electric retractable foot pedal is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an electric suitcase with an electric telescopic foot pedal, including a suitcase body, two foot pedals (left and right), two foot pedal mounting seats (left and right), and a bidirectional electric screw drive mechanism. The two foot pedal mounting seats and the bidirectional electric screw drive mechanism are located in the inner cavity of the suitcase body. The two foot pedal mounting seats are arranged on the left and right sides of the inner cavity of the suitcase body, and the bidirectional electric screw drive mechanism is located between the two foot pedal mounting seats. The two foot pedals are arranged opposite to the left and right sides of the suitcase body. The side of the suitcase body has an opening, and the foot pedals are telescopically mounted in the foot pedal mounting seats on the same side through the opening on the suitcase body. The bidirectional electric screw drive mechanism has two drive screws (left and right), which extend into the foot pedal mounting seats and foot pedals on the same side. Nuts are sleeved on the drive screws and connected to the foot pedals. The bidirectional electric screw drive mechanism drives the nuts to extend and retract through the drive screws, and then drives the foot pedals to extend out of the suitcase body through the nuts.

[0007] Furthermore, the bidirectional electric lead screw drive mechanism includes a motor, a drive box, two drive screws (left and right) and lead screw nuts. The output end of the motor is connected to the drive box, which is located between two foot pedal mounting seats. The output end of the drive box is connected to the ends of the two drive screws (left and right). Lead screw nuts are provided on the rods of the two drive screws (left and right).

[0008] Furthermore, the foot pedal mounting base includes a lower mounting base and an upper cover plate. The top and both sides of the lower mounting base are open. A drive screw extends into the lower mounting base from one side opening. A foot pedal is provided at the opening on the other side of the lower mounting base. An upper cover plate is provided on the opening at the top of the lower mounting base. After the upper cover plate and the lower mounting base are installed, they form a guide channel. The foot pedal extends along the guide channel and protrudes from the housing.

[0009] Furthermore, the foot pedal mounting bracket and the bidirectional electric screw drive mechanism are both mounted on the mounting bracket of the front handlebar assembly.

[0010] Furthermore, the fixing seat is installed on the annular middle frame of the box body.

[0011] Furthermore, the fixed base has two drive mechanism fixing frames on the left and right, and the drive box is located between the two drive mechanism fixing frames and has a connection structure with the drive mechanism fixing frames to realize the installation and fixing of the bidirectional electric screw drive mechanism.

[0012] Furthermore, the outer side of the opening of the box is covered with a decorative sleeve, and the inner side of the opening of the box has a retaining ring. The decorative sleeve is fastened to the retaining ring by a buckle.

[0013] The beneficial effects of this utility model are: the electric suitcase with electric retractable foot pedal of this utility model has the characteristics of simple structure, convenient use and good user experience;

[0014] Specifically, the original fixed or manual pedals are improved to be driven by a two-way electric screw drive mechanism, that is, from manual to electric. Users no longer need to manually disassemble or fold the pedals, making them very convenient to use. Users can also enjoy the convenience brought by automation, and the user experience will be better. Attached Figure Description

[0027] Figures 1 to 9An electric suitcase with retractable foot pedals is shown, comprising a suitcase body 1, two foot pedals 2, two foot pedal mounting seats 3, and a bidirectional electric screw drive mechanism. The two foot pedal mounting seats 3 and the bidirectional electric screw drive mechanism are installed in the inner cavity of the suitcase body 1. The two foot pedal mounting seats 3 are arranged on the left and right sides of the inner cavity of the suitcase body 1, and the bidirectional electric screw drive mechanism is located between the two foot pedal mounting seats 3. The two foot pedals 2 are arranged opposite to the suitcase body 1. The side of the suitcase body 1 has an opening, through which the foot pedals 2 are retractably installed in the foot pedal mounting seats 3 on the same side. The bidirectional electric screw drive mechanism has two drive screws 6, which extend into the foot pedal mounting seats 3 and foot pedals 2 on the same side. Nuts 7 are sleeved on the drive screws 6 and connected to the foot pedals 2. The bidirectional electric screw drive mechanism drives the nut 7 to extend and retract through the drive screws 6, and then drives the foot pedals 2 to extend out of the suitcase body 1 through the nut 7. The nut 7 is fixedly connected to the inner end of the foot pedal 2 by a screw.

[0028] The specific structure of the bidirectional electric lead screw drive mechanism is as follows: it includes a motor 8, a drive box 9, two left and right drive screws 6 and a lead screw nut 7.
