[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Figures 1 to 11The electric luggage case shown has a bendable front handlebar, comprising a case assembly 1, a front handlebar and a front wheel mounted below the front handlebar, the front handlebar having a rotating shaft 6, the front handlebar being rotatably mounted on the case assembly 1 via the rotating shaft 6, the upper handlebar rod of the front handlebar located above the rotating shaft 6 is divided into an upper rod body 2 and a lower rod body 3, a lockable folding structure is provided between the upper rod body 2 and the lower rod body 3, for enabling the upper rod body 2 to be folded forward, and a handle 4 is mounted on the upper part of the upper rod body 2.

[0035] exist Figures 1 to 11 In the embodiment shown, the front and rear positions of the front handlebars are immovable relative to the box body. The box body assembly 1 includes a box body and two rear wheels at the bottom of the box body. A handlebar mounting seat is fixedly mounted on the box body, and the rotating shaft 6 of the front handlebar is rotatably mounted in the mounting seat 8.

[0036] The lockable folding structure includes a folding joint and a locking sleeve 11. The folding joint includes an upper joint structure at the bottom of the upper rod body 2 and a lower joint structure at the top of the lower rod body 3. The upper joint structure and the lower joint structure are hinged by a hinge axis; in the figure, the upper joint structure 5 and the upper rod body 2 are split structures, and the upper part of the upper joint structure 5 has an insert end. The upper joint structure 5 is inserted into the inner hole at the bottom of the upper rod body 2 through the insert end, and is fixed to the inner hole of the upper rod body 2 by interference fit, welding or fastening bolts.

[0037] The locking sleeve 11 is slidably mounted on the upper handlebar, that is, the locking sleeve 11 can be mounted on the upper rod body 2 or the lower rod body 3. When the locking sleeve 11 is mounted on the folding joint, the folding joint is locked, and this position is the locking position of the locking sleeve 11. When the locking sleeve slides away, exposing the folding joint, the folding joint is unlocked, and this position is the unlocking position of the locking sleeve. The position of the locking sleeve 11 is limited by a positioning mechanism, which is used to position the locking sleeve in the locked position and the unlocked position respectively. Of course, the lockable folding structure of the present invention can also adopt other lockable folding structures in the prior art.

[0038] Specifically, the specific structure of the positioning mechanism is as follows: the inner wall of the locking sleeve 11 is provided with grooves 12 distributed up and down and recessed outward, and the side of the upper handlebar rod is provided with a positioning piece mounting hole 13. In the figure, the positioning piece mounting hole 13 is opened on the upper joint structure 5. The positioning piece mounting hole 13 can also be opened on the upper rod body 2 and / or the lower rod body 3. The positioning piece mounting hole 13 can be opened in the direction of the side and / or the front and back; a ball plunger is installed in the positioning piece mounting hole 13, and when the locking sleeve 11 slides upward to the unlocked position, the positioning ball or positioning column of the ball plunger is embedded in the groove 12 on the lower side of the locking sleeve 11, positioning the locking sleeve 11 in the unlocked position; when the locking sleeve 11 slides downward to the locked position, the positioning ball or positioning column of the ball plunger is embedded in the groove 12 on the upper side of the locking sleeve 11, positioning the locking sleeve 11 in the locked position.

[0039] Alternatively, the specific structure of the positioning mechanism is as follows: the inner wall of the locking sleeve 11 is provided with grooves 12 distributed up and down and recessed outward, and the side of the upper handlebar rod is provided with a positioning piece mounting hole 13. In the figure, the positioning piece mounting hole 13 is opened on the upper joint structure 5. The positioning piece mounting hole 13 can also be opened on the upper rod body 2 and / or the lower rod body 3. The positioning piece mounting hole 13 can be opened in directions such as the side and / or the front and back; a spring and a positioning piece pushed out by the spring are provided in the positioning piece mounting hole 13. When the locking sleeve 11 slides upward to the unlocked position, the head of the positioning piece is embedded in the groove 12 on the lower side of the locking sleeve 11, positioning the locking sleeve 11 in the unlocked position. When the locking sleeve 11 slides downward to the locked position, the head of the positioning piece is embedded in the groove 12 on the upper side of the locking sleeve 11, positioning the locking sleeve in the locked position. The positioning piece is usually a positioning ball or a positioning column.

[0040] The bottom of the lower rod body 3 is connected to the front fork 7 through the rotating shaft 6. The front wheel is installed in the front fork 7. In order to prevent accidents due to oversteering during use, a limiter 9 is usually installed under the lower rod body 3 to limit the rotation range of the front handlebar. The limiter 9 cooperates with the mounting seat 8 to achieve limitation. In the figure, both sides of the limiter 9 have limit protrusions 10 extending downward to both sides of the mounting seat 8; in order to ensure smooth rotation of the upper rod body 2, the top of the lower rod body 3 has an arc-shaped give way structure 14 that cooperates with the rotation of the upper rod body 2; in order to improve the strength of the locking sleeve 11, the outside of the locking sleeve 11 has several reinforcing ribs 15.

[0041] When towing is required, the locking sleeve 11 is pushed downward to unlock the folding structure, and the upper rod body of the front handlebar can be bent forward. The electric suitcase can be towed by grabbing the handlebar. Because people can be relatively far away from the body of the electric suitcase, towing is more convenient. In addition, because the towing force is moved downward, the electric suitcase is not easy to turn over, and it is easy to change direction when towing.

[0042] When riding, the locking sleeve 11 is pushed downwards and locked to limit the upper rod 2 and the lower rod 3 to each other, which does not affect the control of the electric suitcase during riding and ensures safety during riding.

[0043] Example 2. This example 2 differs from Example 1 in that the position of the locking sleeve 11 is elastically reset by a spring reset mechanism, which is used to reset the locking sleeve 11 that has slid away from the unlocked position to the locked position. The elastic reset of the locking sleeve 11 by a spring reset mechanism is an existing structure in the prior art. For example, the spring reset mechanism is specifically a reset spring, which is sleeved on the upper handlebar, and the reset spring sleeve is located between the locking sleeve 11 and the upper handlebar. The two ends of the reset spring act on the locking sleeve 11 and the upper handlebar respectively. The thrust of the reset spring pushes the locking sleeve 11 toward the folding joint to form a locked state. When unlocking is required, the locking sleeve 11 is pushed upward, so that the locking sleeve 11 leaves the folding joint to form an unlocked state. The upper rod body 2 can rotate freely. When the upper rod body 2 rotates to be in the same straight line as the lower rod body 3, the reset spring automatically resets the locking sleeve 11 that has slid away from the unlocked position to the locked position, that is, automatically resets it to the folding joint.

[0044] Example 3. The difference between Example 3 and Example 1 is that the electric luggage box is an electric luggage box with an adjustable front handlebar position. The structure of the electric luggage box with an adjustable front handlebar position is as follows: the front handlebar position can be moved forward and backward relative to the box body. The box body assembly 1 includes a box body and an extendable electric telescopic arm inside the box body. The front end of the electric telescopic arm is fixedly installed with a handlebar mounting seat. The rotating shaft 6 of the front handlebar is rotatably installed in the mounting seat 8. The extension and retraction of the electric telescopic arm drives the front handlebar to move forward away from the box body or retract close to the box body.

[0045] In addition, the front handlebar is a three-section retractable handlebar, specifically the upper rod body 2 of the front handlebar is a three-section retractable rod. This design allows the user to push the electric luggage case farther away from the case, making it more convenient to tow. Moreover, because the height of the front handlebar is adjustable, it can better adapt to users of different heights when riding.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
