Specific embodiments

[0025] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0026] As Figure 1As shown in the figure, a logistics electric trolley includes a base 1. A traction component 2 is vertically arranged at the front end of the base 1. Two switching components 3 are distributed below the base 1. Four universal wheels 4 are distributed around the switching component 3. The switching component 3 is rotatably connected to an electric vehicle wheel 5. When manually pushed, the electric vehicle wheel 5 is lifted relative to the switching component 3. When electrically pushed, the electric vehicle wheel 5 descends relative to the switching component 3 and is on the same horizontal plane as the universal wheels 4. Thus, the moving mode can be switched arbitrarily according to the usage requirements, with quick switching and convenient use.

[0027] Specifically, as Figure 2 shown in the figure, the switching component 3 includes a moving frame 301 and a first electric push rod 303. A first spring 304 is arranged between the moving frame 301 and the base 1. When moving on an uneven ground, the first spring 304 can play a certain buffering role for the base 1. Support members 302 are hinged on both sides of the middle of the moving frame 301. The first electric push rod 303 and the support members 302 are fixed below the base 1. The telescopic rod of the first electric push rod 303 is fixedly connected to one end of the moving frame 301. The electric vehicle wheel 5 is rotatably connected to the other end of the moving frame 301. When the telescopic rod of the first electric push rod 303 extends, it will push one end of the moving frame 301 downward. At the same time, the other end of the moving frame 301 will tilt upward accordingly, thereby driving the electric vehicle wheel 5 to move upward for convenient manual pushing. When the telescopic rod of the first electric push rod 303 contracts and drives one end of the moving frame 301 to move upward, the other end of the moving frame 301 will drop accordingly, thereby driving the electric vehicle wheel 5 to move downward. And a driving component is arranged in the electric vehicle wheel 5, which can drive the electric vehicle wheel 5 to rotate accordingly, and then drive the universal wheels 4 to rotate through the base 1, so as to make the trolley achieve the effect of electric pushing.

[0028] As Figures 3 to 4As shown in the figure, a jacking assembly 6 is provided below the front end of the base 1. The jacking assembly 6 includes a mounting plate 601. A sliding cylinder 605 is provided on the mounting plate 601. A support foot 606 is slidably connected inside the sliding cylinder 605. A second spring is provided between the support foot 606 and the sliding cylinder 605. The mounting plate 601 is hinged with a first connecting frame 602. The first connecting frame 602 is hinged with a second connecting frame 603. A foot plate 607 is provided at the end of the second connecting frame 603. A self-locking frame 604 is hinged in the middle of the second connecting frame 603. The self-locking frame 604 is hinged with the support foot 606. A pressing roller 6041 is provided at the end of the self-locking frame 604. An elliptical hole 6042 is provided below the pressing roller 6041. A limiting roller 6031 is provided on the second connecting frame 603. The limiting roller 6031 is slidably connected to the elliptical hole 6042. Press down the foot plate 607 to make one end of the second connecting frame 603 move downward. The other end of the second connecting frame 603 drives the first connecting frame 602 to jack up. While driving the mounting plate 601 and the sliding cylinder 605 to move upward, the limiting roller 6031 will move along with the second connecting frame 603 and slide to the upper end of the elliptical hole 6042, thereby limiting the position of the self-locking frame 604 and making the pressing roller 6041 move upward to abut against the lower end face of the sliding cylinder 605, so that the jacking assembly 6 is in a jacked-up self-locking state. Press down the foot plate 607 to make one end of the second connecting frame 603 move upward. The other end of the second connecting frame 603 drives the first connecting frame 602 to move downward. The limiting roller 6031 will move along with the second connecting frame 603 and slide to the lower end of the elliptical hole 6042, making the pressing roller 6041 move downward to release the self-locking state, thereby reducing the height of the mounting plate 601.

[0029] The traction assembly 2 includes a support plate frame 201 and a handrail 205. A mounting member 202 is provided on the support plate frame 201. A brake handle 203 is provided at one end of the mounting member 202. An acceleration handle 204 is provided at the other end of the mounting member 202. Protective plates 206 are provided at both ends of the handrail 205. The protective plates 206 are arranged on the sides of the brake handle 203 and the acceleration handle 204. The protective plates 206 play a protective role for the brake handle 203 and the acceleration handle 204. The acceleration handle 204 can increase the moving speed of the trolley. When an emergency occurs, the trolley can be stopped by the brake handle 203.

[0030] As Figures 5 to 6As shown in the figure, limiting frames 101 are provided on both the front and rear sides of the base 1. A number of baffles 102 are provided on the left side of the base 1, and a blocking assembly 7 is provided on the right side of the base 1. The blocking assembly 7 includes a second motor push rod 701. The end of the telescopic rod of the second motor push rod 701 is hinged with a moving member 702. The moving member 702 is hinged with a fixing member 703. The fixing member 703 is connected with a fixing rod 704. The end of the fixing rod 704 is connected with a first blocking member 705. The first blocking member 705 is hinged with a connecting member 706. The connecting member 706 is hinged with a second blocking member 707. The second blocking member 707 is hinged to the side of the base 1. The limiting frames 101, the baffles 102 and the blocking assembly 7 all play a role in limiting the goods. When unloading is required, the extension of the telescopic rod of the second motor push rod 701 will drive the moving member 702 to rotate outwards. The rotation of the moving member 702 will drive the fixing member 703 and the fixing rod 704 to rotate outwards. The fixing rod 704 will drive the first blocking member 705 to rotate towards the second blocking member 707, thereby driving the connecting member 706 and the second blocking member 707 to rotate accordingly, so that the included angle between the connecting member 706 and the second blocking member 707 becomes smaller, thus achieving the effect of folding and storing. When transporting goods is required, the contraction of the telescopic rod of the second motor push rod 701 will drive the moving member 702 to rotate inwards. The rotation of the moving member 702 will drive the fixing member 703 and the fixing rod 704 to rotate inwards. The fixing rod 704 will drive the first blocking member 705 to rotate in the opposite direction, thereby driving the connecting member 706 and the second blocking member 707 to rotate accordingly, so that the included angle between the connecting member 706 and the second blocking member 707 becomes larger, making the first blocking member 705 and the second blocking member 707 perpendicular to the base 1, thus achieving the blocking effect.

[0031] A number of rolling cylinders 103 are distributed on the side of the limiting frame 101, which is convenient for pushing the goods, thus achieving the unloading operation.

[0032] Working principle: When a handcart is needed, the switching component 3 drives the electric vehicle wheels 5 to lift up. Hold the handrail 205 and push it to make the universal wheels 4 rotate to drive the cart to move. When electric pushing of the cart is needed, the switching component 3 drives the electric vehicle wheels 5 to move down and be on the same horizontal plane as the universal wheels 4. The electric vehicle wheels 5 start and rotate, driving the universal wheels 4 to rotate through the base 1, so that the cart achieves the effect of electric pushing. When the cart moves to the corresponding position, use the jacking component 6 to lift the base 1 to prevent the cart from sliding, and then fold up the blocking assembly 7 to facilitate the unloading of goods.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
