[0039] Reference Figures 1 to 8 An electric tractor unit, comprising:

[0040] The frame 100 has movable wheels 110 on both the front and rear sides. The front of the frame 100 has a fifth wheel 120 and a first adjustment mechanism 130. The first adjustment mechanism 130 adjusts the fifth wheel 120 to maintain the same height as the movable wheel 110 when deformed.

[0041] A handlebar assembly 200 is disposed at the rear end of the frame 100. The handlebar assembly 200 includes a second adjustment mechanism 210 and a foldable handlebar support mechanism 230. The second adjustment mechanism 210 adjusts the angle of the handlebar support mechanism 230 relative to the frame 100.

[0042] A traction device 300 is disposed at the front end of the frame 100. The traction device 300 is provided with a third adjustment mechanism 310 and a ball joint 320. The third adjustment mechanism 310 adjusts the ball joint 320 to move up and down relative to the frame 100, and adjusts the ball joint 320 to move in the lateral direction of the frame 100. The ball joint 320 is used to detachably connect to the towed object.

[0043] Through the above-described structure, the device effectively improves the efficiency of cargo or truck transfer, especially in narrow areas where the electric tractor can still operate flexibly. The third adjustment mechanism 310 allows for multi-dimensional adjustment of the ball joint 320 in both vertical and lateral directions along the frame 100, making traction connections more convenient and precise, adapting to various traction height and distance requirements, and enhancing the versatility and adaptability of the electric tractor. Simultaneously, the handlebar mechanism 230 of the electric tractor can be adjusted to different angles via the second adjustment mechanism 210; the foldable handlebar mechanism 230 can meet various usage needs. Furthermore, the fifth wheel 120 significantly improves the stability of the electric tractor during traction, effectively preventing the handlebar device 200 from tilting upwards due to uneven force during traction, thus improving the stability and safety of equipment operation. The fifth wheel 120 can also achieve adaptive height adjustment via the first adjustment mechanism 130, maintaining the same height as the other moving wheels 110 during use.

[0044] In this embodiment, the electric tractor is made of carbon steel with a thickness greater than 2mm. Through this structural design, the electric tractor possesses high mechanical strength and load-bearing capacity, adapting to frequent use and complex operating conditions, effectively extending the equipment's service life. Simultaneously, carbon steel has good weldability and processing performance, facilitating mass production and maintenance, and reducing overall manufacturing costs. Furthermore, the thickness of more than 2mm ensures structural strength while also considering the vehicle's lightweight requirements, avoiding excessive weight that could affect operational flexibility. Preferably, the electric tractor is equipped with handles 150 on both sides, allowing users to lift the entire tractor by gripping the handles 150, facilitating traversing steps and storage. This design significantly improves the portability and ease of operation of the electric tractor, making it particularly suitable for work scenarios requiring frequent handling or with limited space.

[0045] In this embodiment, a lateral adjustment rod 140 is provided in the lateral direction of the frame 100, and a plurality of spaced and aligned first adjustment holes 141 are provided on the side of the lateral adjustment rod 140. The third adjustment mechanism 310 includes a lateral adjustment mechanism 311, which includes a lateral adjustment element 3111 and a lateral locking member 3113. The lateral adjustment element 3111 is provided with a first positioning hole 3112 corresponding to the first adjustment hole 141. The first adjustment hole 141 and the first positioning hole 3112 allow the lateral locking member 3113 to be inserted, so that the lateral adjustment element 3111 is movably connected to the lateral adjustment rod 140. With the above structure, the lateral adjustment mechanism 311 can drive the ball joint seat 320 to move along the length direction of the frame 100 to adapt to the traction docking requirements at different distance positions. In use, the user can adjust and fix the ball head seat 320 in multiple positions in the lateral direction by inserting the lateral locking member 3113 into the corresponding first positioning hole 3112 and first adjustment hole 141. The operation is simple and the adjustment is flexible, which improves the adaptability and ease of use of the electric tractor.

[0046] In this embodiment, the third adjustment mechanism 310 further includes a longitudinal adjustment mechanism 312, which includes a longitudinal adjustment element 3121 connected to the transverse adjustment element 3111 and a longitudinal locking member 3123. The longitudinal adjustment element 3121 has multiple spaced and aligned second adjustment holes 3122 along its longitudinal side. The ball joint 320 also includes a connector 321, which has second positioning holes 3211 corresponding to the second adjustment holes 3122. The second positioning holes 3211 and the second adjustment holes 3122 allow the longitudinal locking member 3123 to be inserted, so that the connector 321 is movably connected to the longitudinal adjustment element 3121. With the above structure, the longitudinal adjustment mechanism 312 can drive the ball joint 320 to move up and down vertically to adapt to different height docking requirements. Users can adjust and fix the ball joint 320 in multiple height positions by inserting the longitudinal locking member 3123 into the corresponding second adjustment holes 3122 and second positioning holes 3211. Preferably, the longitudinal adjustment element 3121 and the lateral adjustment element 3111 are arranged approximately perpendicularly. A stable connection between the longitudinal adjustment element 3121 and the lateral adjustment element 3111 can be achieved by fixing a column. The fixing column is connected at approximately 45° to the top of the longitudinal adjustment element 3121 and the end of the lateral adjustment element 3111 near the longitudinal adjustment element 3121. At this time, the structure is approximately a stable triangular structure.

[0047] In this embodiment, the ball joint 320 includes a connecting base 322 and a ball joint 323. The connecting base 322 is connected to the lower end of the connector 321, and the ball joint 323 is detachably disposed at the front end of the connecting base 322. The traction device 300 includes a pressure sensor 330, which is connected to the connecting base 322 and is used to detect the pressure on the ball joint 323. Through this structure, the pressure sensor 330 can monitor the magnitude of the traction force received by the ball joint 323 in real time, and transmit the collected pressure signal to the controller 500. The controller then drives the first adjustment mechanism 130 to adjust the height of the fifth wheel 120 according to the pressure signal, thereby achieving intelligent control and feedback adjustment of the traction process. For example, when the ball joint 323 senses excessive traction pressure, the fifth wheel 120 will deform under the pressure, potentially causing instability in the traction process. In this case, the pressure sensor 330 can drive the controller 500 based on the pressure data, and the controller 500 will automatically adjust the height of the fifth wheel 120, improving user safety and the intelligence level of the electric tractor. Furthermore, the ball joint 323 features a detachable design, allowing users to replace it with different sizes to fit various traction interfaces, facilitating daily maintenance and replacement, and reducing operating costs.

[0048] In this embodiment, a protective box 700 is also included. A power supply device 400 and a controller 500 electrically connected to the power supply device 400 are disposed on the upper end of the frame 100. The power supply device 400 and the controller 500 are located inside the protective box 700. The outer walls of the power supply device 400 and the protective box 700, respectively, are provided with a charging port 410 and a discharging port 420. The power supply device 400 is charged via the charging port 410 or by solar energy, and the power supply device 400 is used to supply power to other devices via the discharging port 420. Through the above structural design, the protective box 700 not only effectively protects the controller 500 and the power supply device 400, but also enhances the energy management and application capabilities of the electric tractor through the design of the charging port 410 and the discharging port 420. For example, in outdoor scenarios without mains power access, the power supply device 400 can be replenished with solar energy; and when power is needed for other devices, it can provide external power through the discharging port 420, significantly improving the adaptability and overall performance of the equipment. Meanwhile, the charging port 410 is designed to adapt to the voltage of various countries. It incorporates an automatic adjustment circuit that automatically detects the input voltage and adjusts the internal circuitry to suit the current voltage level, ensuring a stable and safe power supply. Preferably, the protective box 700 has a high waterproof rating, enabling it to operate normally in harsh weather conditions such as heavy rain. The protective box 700's sealed design effectively prevents rainwater, dust, and other impurities from entering the interior. Furthermore, the protective box 700 is equipped with a cover for convenient maintenance and replacement of the internal power supply unit 400 and controller 500.

[0049] In this embodiment, a drive unit 600 is provided at the lower end of the frame 100, which works in conjunction with the power supply device 400 and the controller 500. The drive unit 600 drives the moving wheel 110 and the fifth wheel 120 to rotate. Through the above structural design, a reasonable layout and intelligent control of the electric tractor's power system are achieved, which not only improves the stability and maneuverability of the entire vehicle but also enhances the electric tractor's adaptability to complex road conditions. Simultaneously, the integrated design between the drive unit 600, the power supply device 400, and the controller 500 makes the overall structure more compact, facilitating maintenance and installation, and improving the reliability and ease of use of the electric tractor.

[0050] In this embodiment, the handlebar device 200 has a handlebar 220 at its upper end. The handlebar 220 is equipped with a brake 221, a switch 222, a power display panel 223, a voice announcer 224, and a speed controller 225. The brake 221 controls the moving wheel 110 at the front end of the frame 100. The switch 222 controls the electric tractor to start or stop. The controller 500 controls the voice announcer 224 to issue a voice announcement when the electric tractor is reversing. The speed controller 225 controls the speed of the electric tractor when it is moving. Through this structural arrangement, the brake 221 is mechanically connected to the moving wheel 110 at the front end of the frame 100, controlling the braking action of the front moving wheel 110 to ensure fast and reliable stopping under different working conditions. The switch 222 controls the power supply of the electric tractor to start and stop. Preferably, the electric tractor is equipped with an external key; inserting the key into the switch 222 starts the electric tractor, and pressing the brake 221 starts the electric tractor moving. The power display panel 223 is electrically connected to the power supply device 400 and can display the remaining power of the power supply device 400 in real time, making it easy for users to monitor the driving status of the electric tractor. When the electric tractor enters the reversing mode, under the control of the controller 500, the voice broadcaster 224 is triggered to issue a prompt tone or voice reminder to improve safety in the working environment. Preferably, the voice broadcaster 224 can be set to different languages ​​for users to choose from. For example, when the electric tractor is reversing, the voice broadcaster will issue a voice warning similar to "Please be careful while reversing" to remind pedestrians and other workers around to pay attention to safety. In addition to the preset safety prompts, the voice warnings may also support user-customized broadcast content to meet special operational needs. The speed controller 225 is used to adjust the travel speed of the electric tractor. After the user selects different gears of the speed controller 225, the speed controller 225 outputs a signal to the controller 500. The controller 500 then controls the speed of the drive unit 600 according to the set gear, thereby realizing the speed adjustment function of the electric tractor. Preferably, the speed controller 225 is a knob with different gears for the user to select.

[0051] In this embodiment, the handlebar mechanism 230 includes a first handlebar 231, a second handlebar 232, and a fixing post 233. The lower end of the first handlebar 231 and the upper end of the second handlebar 232 are respectively provided with through holes. The fixing post 233 passes through the through holes so that the lower end of the first handlebar 231 is movably connected to the upper end of the second handlebar 232. The second adjustment mechanism 210 includes a guide locking member 212 and a guide plate 211 disposed opposite to it. The guide plate 211 is connected to the frame 100. The guide plate 211 is provided with a first guide rail 213. The lower end of the second handlebar 232 is provided with a second guide rail 2321 corresponding to the first guide rail 213. The first guide rail 213 and the second guide rail 2321 allow the guide locking member 212 to be inserted so that the lower end of the second handlebar 232 is movably connected to the guide plate 211. With the above-described structure, the user can adjust the tilt angle of the handle frame structure 230 by sliding the guide locking member 212 in the first guide rail 213 and the second guide rail 2321 according to actual operating needs. Simultaneously, the fixing post 233 is inserted into the corresponding through holes on the first handle frame 231 and the second handle frame 232 to achieve the foldable design of the handle frame mechanism 230. At this time, the first handle frame 231 rotates downwards towards the second handle frame 232 to achieve the folding and storage of the handle frame structure 230. Preferably, the first handle frame 231 and the second handle frame 232 are respectively fixed with studs. The studs on the second handle frame 232 are used to fix the lower end of a snap-fit ​​plate, and then the upper end of the snap-fit ​​plate is movably connected to the studs on the first handle frame 231. At this time, the upper end of the snap-fit ​​plate has a hook structure, allowing the user to store or use the handle frame structure 230 according to actual needs.

[0052] In this embodiment, the fifth wheel 120 is located in the middle of the movable wheel 110 at the rear end of the frame 100, and the first adjustment mechanism 130 is an electronically controlled adjustment structure. After receiving the signal from the pressure sensor 330, the controller 500 controls the first adjustment mechanism 130 to adjust the longitudinal height of the fifth wheel 120. Through this structure, the fifth wheel 120 can maintain the same height as the other movable wheels 110 under different loads or terrain conditions, ensuring uniform force distribution on the entire vehicle during traction and preventing the handlebar device 200 from tilting upwards due to uneven force distribution, thereby significantly improving the stability and operational safety of the electric tractor. Furthermore, the first adjustment mechanism 130, being an electronically controlled adjustment structure, combined with the traction force data collected by the pressure sensor 330, realizes an intelligent adaptive adjustment function for the height of the fifth wheel 120. This allows for height matching without manual intervention, enhancing the adaptability and intelligence level of the electric tractor under complex working conditions.
