[0029] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.
[0030] like Figures 1 to 5 As shown: This embodiment discloses a suitcase with a handle positioning function, comprising a front wheel bracket 4 that can be telescopic relative to a case body 1, the front wheel bracket 4 is connected to a steerable front wheel stem 71, the lower part of the front wheel stem 71 is connected to a front wheel 3 through a front wheel fork 7, and the front wheel stem 71 or / and the front wheel fork 7 are provided with a positioning device. The positioning device can be a positioning decorative cover 5 provided on the front wheel stem 71. Among them, a recessed structure for placing the front wheel stem 71 is provided on the side of the case body 1.
[0031] A pair of rear wheels 2 are usually arranged at the rear end of the box body 1, and the rear wheels 2 are usually electric drive wheels. The front wheel bracket 4 is arranged at the front end of the extension arm 41, and the extension arm 41 can be extended forward or retracted relative to the box body 1, and its extension or retraction method can be realized by using an electric telescopic rod in the prior art.
[0032] The positioning decorative cover 5 includes side faces 51 respectively arranged on both sides, and the distance between the two side faces 51 decreases from the end far from the box body 1 to the end close to the box body 1. The side of the box body 1 is provided with positioning grooves 8 matching the two side faces 51. When the front wheel bracket 4 is in the retracted state, the two side faces 51 fit with the positioning grooves 8, and the front wheel 3 is in the centered state. The two side faces 51 are located at the middle section ( Figure 4 The positioning decorative sleeve 5 is symmetrically arranged with respect to the center (A line in the figure). The side of the positioning decorative sleeve 5 close to the box body 1 is also provided with a side face 52, and the two sides of the side face 52 are respectively connected to the two side faces 51. It can be seen from the above description that the cross section of the positioning decorative sleeve 5 in this embodiment is an isosceles trapezoid as a whole, the two side faces 51 are equivalent to a set of waists of the isosceles trapezoid, and the side face 52 is equivalent to the top edge of the isosceles trapezoid. In some application scenarios, the cross section of the positioning decorative sleeve 5 can also be set to a triangular shape.
[0033] The cross section of the side surface 1 51 is an arc surface protruding outward in the middle. The advantage of such a design is that it is more beautiful visually than a flat design. In addition, when the extension arm 41 is retracted inward, the arc-shaped side surface 1 51 can improve the success rate of the front wheel 3 being centered to a certain extent. It is best to have a chamfered transition between the side surface 1 51 and the side surface 2 52. In practical applications, within a certain range, even if the front wheel 3 is not in the centered state, it can still be turned to the centered state through the extrusion force through the arc-shaped side surface 1 51 and the transition chamfer.
[0034] In this embodiment, the positioning decorative cover 5 is sleeved on the front wheel stem 71 through the central through hole 53, and the central through hole 53 and the front wheel stem 71 are in a locked state so that relative rotation does not occur. If the height of the handlebar 6 needs to be adjusted, the front wheel stem 71 can also be designed to be able to extend and retract relative to the positioning decorative cover 5.
[0035] The cross section of the front wheel bracket 4 is the same as that of the positioning decorative cover 5. The so-called same cross section means that the cross-sectional profile and size of the two are the same. When the front wheel bracket 4 is in the retracted state, the side of the positioning decorative cover 5 is in the same plane as the side of the front wheel bracket 4. For a more beautiful appearance, the gap between the positioning decorative cover 5 and the front wheel bracket 4 should be relatively small. When the front wheel 3 is in the retracted state, the two are visually close to an integrated design.
[0036] The positioning groove 8 is usually a part of the outer shell of the box body 1. The front wheel handle 71 is provided with an operation button 61 on the side close to the box body 1. The operation button 61 is used to operate the electric suitcase. The upper end of the positioning groove 8 is provided with a button receiving groove 81, which is convenient for storing the handle 6.
[0037] The front wheel fork 7 is inclined relative to the front wheel stem 71, which facilitates riding control. When the front wheel bracket 4 is in a retracted state, the front wheel 3 is in a centered state, and the front wheel 3 is in a state of extending toward one side of the box body 1 relative to the front wheel bracket 4, that is, when the front wheel 3 is in a retracted state, the bottom of the front wheel fork 7 is inclined toward one side of the box body 1, which can reduce the protrusion of the front wheel 3 relative to the box body 1.
[0038] The positioning device includes a fork accommodating groove 82 arranged on the box body 1 , and when the front wheel bracket 4 is in a retracted state, the front wheel fork 7 is engaged or in contact with the fork accommodating groove 82 .
[0039] When the front wheel bracket 4 is in the retracted state, the front wheel 3 is in the centered state, and the front wheel 3 is in the state of extending toward one side of the box body 1 relative to the front wheel bracket 4 .
[0040] When in use, when the front wheel 3 is in the extended state, that is, Figure 2As shown, the user can control the direction of the front wheel 3 by operating the handle 6, and then realize steering. In this process, the positioning decorative cover 5 can rotate relative to the front wheel bracket. When the front wheel 3 needs to be stored, the front wheel bracket 4 is retracted to the inside of the box body 1 by controlling the contraction of the extension arm 41, and the positioning decorative cover 5 is brought into contact with the positioning groove 8. As the extension arm 41 is contracted, the side of the positioning decorative cover 5 and the side of the positioning groove 8 can be properly fitted by themselves, and the front wheel 3 is in a centered state.
[0041] like Figure 6 As shown: the positioning device includes a fork accommodating groove 82 arranged in the box body 1. When the front wheel bracket 4 is in a retracted state, the front wheel fork 7 is engaged or contacted with the fork accommodating groove 82, so that the front wheel fork 7 can also be positioned in a centered state.
[0042] like Figure 7 As shown: the positioning device is a positioning block 9 arranged on both sides of the front wheel stem 71. When the front wheel bracket 4 is in a retracted state, the positioning blocks 9 on both sides are in contact with the side of the box body 1 at the same time, so that the front wheel fork 7 can also be positioned in a centered state.
[0043] Compared with the prior art, this embodiment can realize the centering and locking of the front wheel 3 by cooperating the positioning decorative cover 5 with the positioning groove 8 on the side of the case 1, which is convenient for the user to push the suitcase or store the suitcase. When the positioning decorative cover 5 is inside the positioning groove 8, the appearance of the entire suitcase is more regular. The operating handle 6 at the upper end is also closer to the case 1 due to the existence of the button receiving groove 81, which improves the compactness of the product in the storage state and is conducive to the transportation and storage of the product.
[0044] The outer contour of the positioning decorative cover 5 is the same as the outer contour of the front wheel bracket 4. When the front wheel 3 is in the storage state, the outer contours of the two are flush, which is more visually beautiful.
[0045] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
