[0049] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] Reference Figure 1-Figure 9 , a foldable outdoor electric trailer, comprising:

[0051] A crossbeam assembly 1; two folding portions 202, mounted on the crossbeam assembly 1, and configured to simultaneously move toward or away from the center axis of the crossbeam assembly 1; two driving portions 102, mounted on the crossbeam assembly 1, connected to the folding portions 202, and configured to provide driving force for the folding portions 202 to rotate on the crossbeam assembly 1; two side frame assemblies 203, mounted on the corresponding two folding portions 202, connected to the driving portions 102, and configured to move toward or away from the center line of the crossbeam assembly 1.

[0052] The driving unit 102 adopts a servo motor and may also adopt a stepping motor. Through the electric control of the driving unit 102, the two folding parts 202 can realize precise automatic folding, thereby quickly shrinking the frame of the electric trailer. This design not only improves the convenience of operation, but also significantly improves the folding efficiency and accuracy. The driving unit 102 can also control the two side frame assemblies 203 to move closer to the crossbeam assembly 1, thereby realizing the compactness of the overall structure and space optimization. This intelligent control method not only simplifies the operation process, but also ensures the stability and safety of the frame during the folding and shrinking process.

[0053] Two folding frame assemblies 201 are arranged at both ends of the beam and connected to the two side frame assemblies 203, and the center points of the two folding frame assemblies 201 and the two side frame assemblies 203 are connected to form a virtual rectangle; two connecting parts 2 are respectively installed at both ends of the beam, and the folding part 202 is connected to the connecting part 2.

[0054] The folding frame assembly 201 is in a scissor-like shape. The scissor-like shape design enables the folding frame assembly 201 to maintain a stable and smooth movement trajectory during folding and unfolding. This shape not only ensures the firmness and stability of the structure, but also makes the folding process more efficient and convenient. The scissor-type folding frame assembly 201 is composed of a series of interlaced rods to form an opening and closing structure similar to scissors. When folding, these rods can be retracted according to specific angles and trajectories, making the entire trailer structure compact and easy to carry. When unfolding, the scissor-type folding frame assembly 201 can quickly return to its original state, providing stable support and carrying capacity.

[0055] When the folding portion 202 is bent, the side frame assembly 203 can move toward the cross beam. This continuous action not only optimizes the space occupancy, but also further promotes the bending of the folding portion 202 on the connecting portion 2. During the bending process of the folding portion 202, the height of the cross beam is increased, and the folding frame assembly 201 can also fold and deform accordingly, ensuring the stability and coordination of the overall structure.

[0056] An adjustment groove 204 is provided on one side of the connecting part 2, and one end of the folding part 202 is connected to the adjustment groove 204. The driving part 102 includes: a rotating shaft 101, which is installed on the power shaft of the driving part 102; a first gear 103, which is installed at one end of the rotating shaft 101; a second gear 104, which is connected to the first gear 103; a connecting rod 205 is connected to one side of the connecting part 2, one end of the connecting rod 205 is connected to the second gear 104, and the other end of the connecting rod 205 passes through the connecting part 2 and is connected to the folding part 202; a winding wheel 105, which is installed on the rotating shaft 101; a traction member 106, one end of which is connected to the winding wheel 105, and the other end is connected to the side frame assembly 203, and is configured to pull the side frame assembly 203 to move when the winding wheel 105 rotates.

[0057] The second gear 104 adopts a half gear, and the traction part adopts a nylon belt or a nylon rope. The adjustment groove 204 opened on one side of the connecting part 2 enables the folding part 202 to be flexibly connected thereto, which provides convenience for the folding and unfolding of the structure. The linkage mechanism of the rotating shaft 101 of the driving part 102, the first gear 103 and the second gear 104 ensures the efficient transmission of power. The second gear 104 adopts a half gear and is not subject to the continuous meshing control of the first gear 103. The half gear can make the second gear 104 rotate only half a circle and drive the folding part 202 to rotate. In the remaining process, the traction member 106 can be continuously wound up and the folding effect can be achieved. The connecting rod 205 not only enhances the stability of the structure, but also enables the second gear 104 to directly act on the folding part 202 to achieve precise bending control. When the winding wheel 105 rotates, the traction member 106 can accurately pull the side frame assembly 203 closer to or away from the crossbeam, thereby achieving rapid and accurate positioning of the side frame assembly 203 and ensuring the stability and safety of the entire folding process.

[0058] A bearing seat 107 is connected to one side of the crossbeam, and the rotating shaft 101 passes through the bearing seat 107 to provide rotation support for the rotating shaft 101. The bearing seat 107 not only provides a stable rotation support for the rotating shaft 101, but also ensures the stability and smoothness of the rotating shaft 101 during rotation, effectively reduces the friction and wear of the rotating shaft 101, prolongs its service life, and also improves the reliability and durability of the entire structure.

[0059] Two universal wheels 4 are installed at the bottom of one of the two side frame assemblies 203 to provide a forward direction for the trailer; two driving wheels 5 are installed at the bottom of the other side frame assembly 203 of the two side frame assemblies 203 to provide forward power for the trailer; the pull rod part 3 is installed on the side frame assembly 203; the folding handle 301 is connected to the pull rod part 3 through a rotating shaft, a plurality of protrusions are formed on the rotating shaft, a plurality of grooves are formed on the pull rod part 3, the protrusions are connected in the grooves, the folding handle 301 is locked on the pull rod part 3 through the protrusions, and the folding handle 301 can be rotated by 1. Lower the use height of the folding handle 301; the regulator 302 is installed on the folding handle 301 and is used to adjust the rotation speed of the driving wheel 5; the power supply unit 6 is detachably installed on the side frame assembly 203 away from the pull rod part 3, and is used to provide power for the driving wheel 5 and the driving part 102; the control unit 7 is installed on one side of the power supply unit 6 and is used to receive and send command signals; the indicator light 303 is installed on the folding handle 301 and is used to indicate the power level of the power supply unit 6. The power supply unit 6 adopts a battery and can also adopt a UPS. The control unit 7 adopts a power controller and can also adopt a PLC controller.

[0060] By installing two universal wheels 4 and two driving wheels 5, the trailer has the ability to move and turn. The universal wheels 4 enable the trailer to easily change direction, while the driving wheels 5 provide forward power, ensuring the stable driving of the trailer, so that the trailer can flexibly cope with various complex environments and improve work efficiency; the design of the pull rod 3 and the folding handle 301 enables the trailer to be easily controlled by the operator, the angle adjustment of the folding handle 301 enables operators of different heights to find an operating position suitable for themselves, and the installation of the adjuster 302 enables the operator to easily adjust the driving position. The rotation speed of the wheel 5 can be controlled to achieve precise control of the trailer speed. The combination of the power supply unit 6 and the control unit 7 enables the trailer to achieve intelligent management of the power supply. The control unit 7 can receive and send command signals to ensure the normal operation of the driving wheel 5 and the driving unit 102. The indicator light 303 provides the operator with a real-time reminder of the power level of the power supply unit 6, avoiding unexpected situations caused by insufficient power and improving the safety and reliability of the trailer. Efficient space utilization and structural stability: the power supply unit 6 is installed on the side frame assembly 203 away from the pull rod part 3 to balance the weight distribution of the trailer.

[0061] During use, the folding portion 202 can be driven by the driving portion 102 to simultaneously approach or move away from the central axis of the beam assembly 1, thereby realizing the folding and unfolding function of the trailer. The driving portion 102 transmits power through the rotating shaft 101 installed on the power shaft. When the driving portion 102 is working, the rotating shaft 101 drives the first gear 103 to rotate, and then drives the second gear 104 to rotate. The rotation of the second gear 104 will be converted into the rotation of the folding portion 202 through the connecting rod 205, thereby realizing the rotation of the folding portion 202 on the beam assembly 1. The height of the beam is increased during the bending process of the folding portion 202, and the folding frame assembly 201 can also fold and deform accordingly. At the same time, the driving portion 102 also has the function of towing the side frame assembly 203 to move. When the winding wheel 105 rotates with the rotating shaft 101, the towing member 106 will be wound or released accordingly, thereby towing the side frame assembly 203 to approach or move away from the beam, and the two universal wheels 4 provide the trailer with a forward direction. The foldable outdoor electric trailer can be controlled by the pull rod 3, and the folding handle 301 can be folded according to the needs of the user. The regulator 302 can adjust the speed of the driving wheel 5 to adapt to different road conditions and driving requirements. The power supply unit 6 provides power for the driving wheel 5 and the driving unit 102. The control unit 7 is used to receive and send command signals to realize the user's intelligent control of the trailer. The indicator light 303 is installed on the folding handle 301 to prompt the power level of the power supply unit 6, so that the user can understand the power status in time and ensure the normal use of the trailer. The foldable outdoor electric trailer controls the rotation of the folding part 202 and the movement of the side frame assembly 203 through the driving unit 102 to realize the folding and unfolding functions of the trailer, and realizes the movement of the trailer through the driving wheel 5 and the universal wheel 4. At the same time, the user can realize the intelligent control of the trailer and the power status monitoring through the control unit 7, the regulator 302 and the indicator light 303.

[0062] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0063] Through the electric control of the driving part 102, the two folding parts 202 can automatically move closer to or farther away from the central axis of the beam assembly 1 at the same time, thereby realizing the automatic folding of the trailer, changing the traditional cumbersome operation of manually lifting the folding part of the chassis, greatly reducing the labor intensity of the user, and being able to quickly complete the folding or unfolding in a short time, thereby improving the use efficiency. The linkage design of the folding part 202 and the side frame assembly 203 enables the side frame assembly 203 to move closer to or farther away from the beam, further improving the smoothness and stability of the folding process.

[0064] Through the automated folding mechanism, a single person can easily complete the folding process, reducing labor costs and improving the convenience of operation.

[0065] It is not only suitable for lightweight trailers, but also can cope with heavier trailers loaded with batteries, electric motors and other equipment. Through the powerful power of the driving unit 102, even heavy trailers can be easily folded, showing strong adaptability.
