[0034] Please also refer to Figures 1 to 6 The present embodiment provides a manually foldable electric luggage case, comprising a case body 100, a steering mechanism 200, a folding device 300, and a positioning structure. The case body 100 comprises a top wall 130 for sitting, a front wall 140, and a rear wheel 120 arranged at the bottom of the case body 100, and the case body 100 has a space for accommodating clothes; the lower part of the steering mechanism 200 is provided with a front wheel 260 through a front fork 250, and the steering mechanism 200 is used to control the steering of the front wheel 260; the first end of the folding device 300 is connected to the case body 1 00 is hinged, the second end of the folding device 300 is movably connected to the steering mechanism 200, and the second end of the folding device 300 is movably arranged in the vertical direction, so that the second end of the folding device 300 can be folded or unfolded by moving vertically on the steering mechanism 200, thereby driving the steering mechanism 200 to move toward or away from the box body 100; a positioning structure is arranged on the steering mechanism 200, and the positioning structure is used to position and fix the second end of the folding device 300 along the vertical movement.
[0035] As can be seen, in the manually foldable electric suitcase of this embodiment, a user can sit on the top wall 130 of the suitcase body 100, and the suitcase body 100 has space for storing clothes. When the user needs to ride, the second end of the folding device 300 moves vertically on the steering mechanism 200 to expand, thereby driving the steering mechanism 200 to move away from the suitcase body 100 to switch to the expanded state, thereby moving the steering mechanism 200 and the front wheel 260 away from the suitcase body 100 to increase the sitting space, allowing the user to stretch their limbs when riding, so that the user can obtain a more comfortable riding posture, which is beneficial for the user to control the steering when riding, thereby enhancing the user's riding experience and riding pleasure. When riding is not required, the second end of the folding device 300 moves vertically on the steering mechanism 200 to close, thereby driving the steering mechanism 200 to move toward the suitcase body 100 to switch to the closed state, thereby allowing the steering mechanism 200 and the front wheel 260 to be folded close to the suitcase body 100, thereby reducing the space occupied by the entire suitcase, making it easier to store, carry and transport, and convenient to use.
[0036] In this embodiment, the folding device 300 includes a first folding rod 310 and a second folding rod 320, the middle part of the first folding rod 310 is hinged to the middle part of the second folding rod 320, the first end of the first folding rod 310 is hinged to the front wall 140 of the box body 100, and the second end of the first folding rod 310 is vertically movably arranged on the steering mechanism 200, the first end of the second folding rod 320 is hinged to the steering mechanism 200, and the second end of the second folding rod 320 is vertically movably arranged on the front wall 140 of the box body 100, wherein the positioning structure is used to position and fix the second end of the first folding rod 310 along the vertical movement, so as to position the folding device 300 in a closed state or an unfolded state through the positioning structure.
[0037] The first folding rod 310 and the second folding rod 320 of the folding device 300 are arranged crosswise to improve the stability and reliability of the structural design, so that the user is safer when riding. Figure 1 As shown, the folding device 300 is folded to move the steering mechanism 200 toward the direction of the box body 100, thereby switching to the folded state. After the folding, the luggage box body 100 has a small volume and basically does not occupy too much space, thereby facilitating storage and transportation. Figure 2 As shown, the folding device 300 is unfolded to move the steering mechanism 200 away from the box body 100 and thus switched to the unfolded state, thereby facilitating riding.
[0038] It should be noted that the front wheel 260 adopts a hub motor wheel, and the controller controls the rotation of the hub motor front wheel 260, and the rear wheel 120 follows the rotation of the front wheel 260. The user sits on the top wall 130 of the box body 100 and holds the handle 242 above the steering mechanism 200 with both hands or one hand to control the steering of the front wheel 260 by rotating the steering mechanism 200, thereby realizing riding the suitcase on the road.
[0039] Specifically, the folding device 300 also includes a first guide member and a second guide member. The first guide member is arranged at the second end of the first folding rod 310.

In this way, when the folding device 300 is unfolded or closed, the first guide member moves along the guiding direction of the first track, and the second guide member moves along the guiding direction of the second track, thereby improving the stability and compactness of the structural design, making folding and storage simple and convenient, and riding safe and reliable.
[0040] When the folding mechanism 310 is in a state of being easily moved, the folding mechanism 310 can be turned away from the support frame 312 by turning the folding mechanism 312 to a higher position, thereby making the folding mechanism 310 easier to move and the folding mechanism 310 to a higher position.
[0041] Furthermore, the first rollers 311 are arranged in pairs, and the two first rollers 311 are respectively located on both sides of the second end of the first folding rod 310, and the number of the first guide grooves 222 is two. The two first rollers 311 are respectively arranged on the two first guide grooves 222 in a one-to-one correspondence; the second rollers 321 are arranged in pairs, and the two second rollers 321 are respectively located on both sides of the second end of the second folding rod 320, and the number of the second guide grooves 111 is two. The two second rollers 321 are respectively arranged on the two second guide grooves 111 in a one-to-one correspondence. Such an arrangement can ensure that the first rollers 311 roll smoothly along the first guide grooves 222, and can also ensure the stability and reliability of the structural assembly.
[0042] Among them, the opposite side walls of the first guide groove 222 are each provided with a first cylindrical rubber strip, and the two first cylindrical rubber strips are respectively tightly attached to the outer circumferential surface of the first roller 311; the opposite side walls of the second guide groove 111 are each provided with a second cylindrical rubber strip 112, and the two second cylindrical rubber strips 112 are respectively tightly attached to the outer circumferential surface of the second roller 321.
[0043] In this embodiment, the steering mechanism 200 includes a steering mounting portion and a steering rod. The steering rod is rotatably mounted on the steering mounting portion. The steering rod is used to control the steering of the front wheel 260. The second end of the first folding rod 310 of the folding device 300 is vertically movably mounted on the steering mounting portion.
[0044] Specifically, the positioning structure includes a positioning pin 241, and the steering mechanism 200 is provided with one or more positioning holes 232 adapted to the positioning pin 241, so that the positioning pin 241 can be inserted into the positioning hole 232 to achieve the positioning and fixation of the second end of the folding device 300. The number of positioning holes 232 can be two, and the two positioning holes 232 are arranged at intervals along the vertical direction, so that the positioning pin 241 can be inserted into the two positioning holes 232 respectively to position and fix the folding device 300 in the unfolded state and the closed state.
[0045] Furthermore, the steering rod includes a cylinder 230 and a telescopic rod 240. The lower end of the telescopic rod 240 is slidably inserted into the cylinder 230. The upper end of the telescopic rod 240 is provided with a handle 242. The cylinder 230 is rotatably mounted on the steering mounting portion. The positioning hole 232 is provided on the cylinder 230. The positioning pin 241 is correspondingly provided in the telescopic rod 240. An elastic member is provided between the positioning pin 241 and the inner wall of the telescopic rod 240. The elastic member can be a spring. The elastic member applies a force to the positioning pin 241 in the direction of passing through the telescopic rod 240 through the elastic member, so that the positioning pin 241 is pulled out of the telescopic rod 240. The folding device 300 is locked and unlocked when the folding device 300 is unlocked. The folding device 300 is locked and unlocked when the folding device 300 is unlocked. The folding device 300 is locked and unlocked when the folding device 300 is unlocked.
[0046] In addition, a strip-shaped slot 231 is vertically opened on the side wall of the cylinder 230, and the second end of the folding device 300 passes through the strip-shaped slot 231 and is rotatably connected to the lower end of the telescopic rod 240, so that the second end of the first folding rod 310 of the folding device 300 is driven to move vertically by the telescopic rod 240 in the cylinder 230, thereby making the folding device 300 fold or unfold. In this way, the second end of the first folding rod 310 is rotatably connected to the lower end of the telescopic rod 240, so that the user can push and pull the telescopic rod 240 by hand. 40 can drive the folding device 300 to fold or unfold, so as to jointly adjust the state of the folding device 300 and the height of the telescopic rod 240, and the telescopic rod 240 of the steering rod and the cylinder 230 rotate together to drive the front wheel 260 to steer. When the telescopic rod 240 telescopes and slides up and down in the cylinder 230, the corresponding movement of the second end of the first folding rod 310 is avoided by providing a strip groove 231 on the cylinder 230 to avoid structural interference. The mechanism operates stably and reliably, and riding is safer.
[0047] In some embodiments, the positioning structure includes a tightening ring 400, which is sleeved on the steering mechanism 200, so that the second end of the folding device 300 is positioned and fixed along the vertical movement by tightening the tightening ring on the steering mechanism 200, wherein the tightening ring 400 is fixed to the upper end of the cylinder 230 or the upper end of the mounting sleeve 220, so that the outer peripheral surface of the telescopic rod 240 is tightened by the tightening ring 400, thereby limiting the telescopic sliding of the telescopic rod 240 relative to the cylinder 230, thereby realizing the positioning and fixing of the vertical movement of the second end of the first folding rod 310, so that the folding device 300 is locked in the expanded state or the closed state.
[0048] Specifically, the tightening ring 400 includes a C-ring 410, a pin rod 420 and a cam handle 430. The C-ring 410 is installed at the upper end of the cylinder 230 or the upper end of the mounting sleeve 220, and through holes are respectively opened at both ends of the C-ring 410. The pin rod 420 is passed through the through holes at both ends of the C-ring 410. The cam handle 430 is rotatably set at one end of the pin rod 420, so that the two ends of the C-ring 410 are approached to each other by rotating the cam handle 430, thereby reducing the inner diameter space of the C-ring 410, and then tightening the outer circumference of the telescopic rod 240 for positioning and fixing.
[0049] In this embodiment, the steering mounting portion includes a mounting seat 210 and a mounting sleeve 220. The mounting sleeve 220 is arranged on the mounting seat 210.

The first guide member is arranged in the first cavity 221. The two first guide grooves 222 are respectively provided on the opposite side walls of the first cavity 221. In this way, the mounting structure is hidden in the first cavity 221, making the structure of the suitcase compact and the appearance more beautiful.
[0050] Specifically, a second cavity 110 is opened on the front wall 140 of the box body 100, a second guide member is arranged in the second cavity 110, and two second guide grooves 111 are respectively arranged on the opposite side walls of the second cavity 110. The first end of the first folding rod 310 is hinged in the second cavity 110 through a hinge shaft, and the first end of the second folding rod 320 is hinged in the first cavity 221 through a hinge shaft. Such an arrangement enables the folding device 300 to be stored between the first cavity 221 and the second cavity 110 when the folding device 300 is in a closed state, which basically does not affect the external appearance of the suitcase, and the structure is compact, which further reduces the volume of the suitcase and occupies less space.
