[0025] The specific embodiments of the present application will be further described below with reference to the accompanying drawings:
[0026] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0027] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0028] As Figures 1-3As shown, a children's toy trailer includes a base 1, a control lever 2, a motor drive unit 3, a battery, wheels 5, and a folding body 6. The control lever 2 is installed at the front of the base 1. The motor drive unit 3 and a battery box 4 are installed inside the base 1, containing a battery that provides power to the motor drive unit 3. Wheels 5 are installed at the bottom of the base 1, preferably four in total, with two larger diameter wheels at the rear and two smaller diameter wheels at the front. The children's toy trailer is a four-wheeled toy car. The motor drive unit 3 drives the rear wheel axles to rotate, thereby driving the rear wheels 4 to rotate, thus moving the trailer. The folding body 6 is installed on top of the base 1. When the folding body 6 is in the unfolded state, it stands upright. Figure 1 As shown, the folding body 6 is in the folded / retracted state; the folding body 6 is laid flat as shown. Figure 3 As shown.
[0029] like Figure 4 and 5 As shown, the folding vehicle body 6 includes a front body panel 61, a rear body panel 62, a left body panel 63, and a right body panel 64. The front body panel 61 is hinged to the front of the base 1, the rear body panel 62 is hinged to the rear of the base 1, the left body panel 63 is hinged to the left side of the base 1, and the right body panel 64 is hinged to the right side of the base 1. When the folding vehicle body 6 is in the unfolded state, the front body panel 61, the rear body panel 62, the left body panel 63, and the right body panel 64 stand upright and surround each other to form a cavity. The cavity has enough space to hold various toys and other items. When the folding vehicle body is in the folded-down state, the front body panel 61, the rear body panel 62, the left body panel 63, and the right body panel 64 lie flat. This not only saves space, but also allows for the placement of boxes on top for use as a transport vehicle. The distance between the front body panel 61 and the rear body panel 62 is greater than the height of a single front body panel 61 and rear body panel 62; this ensures that the front body panel 61 and rear body panel 62 will not collide when folded forward and backward. The distance between the left body panel 63 and the right body panel 64 is greater than the height of the left body panel 63 and right body panel 64; this ensures that the left body panel 63 and right body panel 64 will not collide when folded left and right. When folding the body, the front and rear body panels are folded first, and then the left and right body panels are folded.
[0030] like Figures 6-8As shown, the front body plate 61 comprises a main plate 611, a connecting column 612, a rotating block 613, a rear frame 614 and a main plate limiting block 615. The connecting column 612 is fixedly installed on the left and right sides of the main plate 611, the rotating block 613 is inserted below the connecting column 612, the rotating block 613 is provided with a first rotating shaft installed on the vehicle base 1, the rear frame 614 is installed on the back of the main plate 611, the main plate limiting block 615 is installed on the left and right sides of the rear frame 614, the main plate limiting block 615 is connected below the connecting column 612, and a limiting protrusion is arranged on the outer side of the main plate limiting block 615. When the main plate 611 is driven to rotate by hand, the main plate 611 rotates around the first rotating shaft, and the flat or upright state is switched. The main plate limiting block 615 will rotate with the main plate 611. When the main plate 611 is unfolded and rotated to the appropriate position, the limiting protrusions of the left and right main plate limiting blocks 615 will abut against the left and right body plates 63 and 64, thereby limiting the unfolded position of the main plate 611.
[0031] Specifically, the rear frame 614 is provided with a locking mechanism, which comprises a front shell 616, a rear shell 617, a driving plate 618, a left locking pin 619, a right locking pin 6110, a left limiting column 6111 and a right limiting column 6112. The front shell 616 and the rear shell 617 are respectively installed on the front and rear of the rear frame 614. The driving plate 618 is installed at the bottom of the front shell 616. The left locking pin 619 is installed on the left side of the inside of the front shell 618. The right locking pin 6110 is installed on the right side of the inside of the front shell 618. The left locking pin 619 and the right locking pin 6110 are mirror images. The left limiting column 6111 is sleeved on the inner end of the left locking pin 619. The right limiting column 6112 is sleeved on the inner end of the right locking pin 6110. The driving plate 618 is provided with a left inclined groove 618a and a right inclined groove 618b. The front shell 616 is provided with a left transverse groove 616a and a right transverse groove 616b. The left limiting column 6111 is inserted into the left inclined groove 618a and the left transverse groove 616a. The right limiting column 6112 is inserted into the right inclined groove 618b and the right transverse groove 616b. The driving plate 618 controls the left locking pin 619 and the right locking pin 6110 to extend into or out of the main plate limiting block 615. The driving plate 618 is provided with a vertical groove 618c, which is located at the middle position between the left inclined groove 618a and the right inclined groove 618b. The inside of the front shell 616 is provided with a middle limiting column 6113, which passes through the vertical groove 618c. The working principle of the locking mechanism is as follows: pulling the driving plate 618 downward moves the left limiting column 6111 and the right limiting column 6112 through the left inclined groove 618a and the right inclined groove 618b. Due to the limiting action of the left transverse groove 616a and the right transverse groove 616b, the left limiting column 6111 and the right limiting column 6112 will only move horizontally. The left limiting column 6111 is located at the left end of the left transverse groove 616a, and the right limiting column 6112 is located at the right end of the right transverse groove 616b. The left locking pin 619 and the right locking pin 6110 extend out of the main plate limiting block 615 and are inserted into the lock holes of the left and right body plates. Similarly, when the driving plate 3 is pushed upward, the left locking pin 619 and the right locking pin 6110 will extend into the main plate limiting block 615.
[0032] As Figures 9-11 shown, the left body plate 63 includes an outer support frame 631, two inner side plates 632 mounted inside the outer support frame 631, a rotating ring 633 welded to the bottom of the outer support frame 631 on both sides, and a fixed block 634, the rotating ring 633 is sleeved on the second rotating shaft 635 of the fixed block 634, the fixed block 634 is installed on the side of the vehicle base 1, the outer support frame 631 is provided with a main plate limiting groove 6311 matched with the limiting protrusion of the main plate limiting block 615 and a lock hole 6312 matched with the lock pin, the rotating ring 633 is provided with a rotating limiting column 636 in front, the rotating limiting column 636 is provided with a rotating limiting protrusion 637, and the second rotating shaft 635 is provided with a rotating limiting groove 638. When the left body plate 63 needs to be rotated to switch between the folded and unfolded states, the rotating ring 633 will rotate with the inner side plates 632, and the rotating limiting column 636 will rotate with the rotating ring 633, since the rotating limiting protrusion 637 is located in the rotating limiting groove 638, the rotating range of the rotating limiting protrusion 637 is limited by the rotating limiting groove 638, which in turn affects the rotating angle of the rotating ring 633. The front body plate 61 and the rear body plate 62 are the same in structure and mirror-symmetric to each other, and the left body plate 63 and the right body plate 64 are the same in structure and mirror-symmetric to each other.
[0033] Specifically, the middle part of the vehicle base 1 is provided with a recessed storage box 7 to increase the capacity, and the upper part of the control rod 2 is provided with a power button 8 and a starting pull rod 9, after pressing the power button 8, the toy trailer is powered on, and after pulling the starting pull rod 9, the motor driving device 3 starts to work to drive the trailer to move forward.
[0034] The above is a further detailed description of the present application in combination with a specific preferred embodiment, which cannot be considered as limiting the specific implementation of the present application to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, some simple deductions or replacements can be made without departing from the concept of the present application, which should be considered as falling within the protection scope of the present application.
