Problems solved by technology

[0002] Carts are a common tool in life. Existing carts are generally divided into electric carts or manual carts. As the name implies, electric carts are carts driven by electricity. The body of the existing electric carts Basically, four-wheel drive is adopted, and the existing four-wheel electric carts are not suitable for special occasions with complex terrains such as field work, emergency rescue, battlefield materials and transport of the wounded
At the same time, most of the existing trolley frame structures with a load of more than 200kg are not suitable for carrying with the car, so a frame structure of a foldable portable electric trolley is proposed to solve the above-mentioned problems

Embodiment 1

[0032] see figure 1 , figure 2 and Figure 4 , including the frame middle section 2, the frame front section 3 and the frame rear section 1, the frame middle section 2 includes two frame main beams 202 and a support base 201, the frame front section 3 is installed at the front end of the frame main beam 202, The rear section 1 of the frame is installed at the rear of the main beam 202 of the frame. The rear section 1 of the frame includes a handle 101. Both front ends of the handle 101 are hinged with the rear end of the main beam 202 through the folding hinge 102. The front end of the beam 202 is provided with an opening slot 2021 and a positioning pin hole 2022, and the front end of the frame main beam 202 is installed with a locking buckle 4 for adjusting the opening slot 2021, which can limit the front end of the frame main beam 202. , the front section 3 of the frame includes two circular tubes 301 which are adapted to the inner diameter of the main beam 202 of the fra...

Embodiment 2

[0034] see figure 1 and figure 2 , both ends of the inner side of the two frame main beams 202 are fixedly connected with reinforcing square tubes 203, and the inner sides of the two reinforcing square tubes 203 are provided with traction points 6, and the traction points 6 set by the reinforcing square tubes 203 can be driven. In the middle, the human-assisted traction is realized through the traction belt, and the mutual assistance of the human and the vehicle can be realized in special occasions, and the vehicle has a stronger passability. The mooring points 5 can be used to drag and haul other vehicles or objects through the traction belt, saving the physical strength of the pusher. There are several mooring points 5 on both sides of the main beam 202 of the frame. The strap is tied to the anchor point 5 on the main beam 202 of the frame, and the strap is used to constrain the goods, that is, it can prevent the goods from slipping off the support frame, that is, it is fu...

Embodiment 3

[0036] see figure 1 , figure 2 and image 3 , the support base 201 includes three support transverse tubes 2011 laterally installed in the inner middle of the two frame main beams 202 and support rods 2012 fixedly installed on both sides of the bottom of the support transverse tubes 2011. The side support rods 2012 are respectively fixed and connected to form a triangular stable structure. The connection between the supporting horizontal square tube 2011 and the reinforcing square tube 203 and the frame main beam 202 is provided with a semicircular stop, and the support base 201 of the middle section 2 of the frame is supported by The horizontal square tube 2011 and the support rod 2012 form a stable triangular structure, and cooperate with the frame main beam 202 to form a frame structure as a whole.

[0037] When using the present invention, if the device needs to be unfolded for use, the handle 101 needs to be rotated and unfolded and locked with the folding hinge 102 as...

Abstract

The invention relates to the technical field of electric trolleys, and particularly discloses a folding type portable electric trolley frame structure which comprises a frame middle section, a frame front section and a frame rear section, the frame middle section comprises two frame main beams and a supporting base, the frame front section is installed at the front ends of the frame main beams, and the frame rear section is installed at the rear end of the frame main beams. The frame rear section is mounted at the tail part of the frame main beam; the occupied area is reduced after the frame rear section is folded and the frame front section is contracted, so that the folding frame is easier to be plugged into a carriage of a transport vehicle and a family car, is convenient to carry, and can be used in special occasions such as the field and the like, and the supporting base of the frame middle section forms a stable triangular structure through the supporting transverse square pipes and the supporting rods; and a frame structure is integrally formed in cooperation with the frame main beam, and the structure can well resist torque, ensure the bearing capacity and enhance the trafficability of the vehicle.
